What Does “Root” Mean?

the “root” translates as “root.” As its name suggests, the “root” allows you to elevate the user rights of an Android terminal as “Super User,” also known as “superuser.” Thanks to this, the user can access the files located at the smartphone’s root, that is to say, its system. After validating the authorization request (temporary or permanent), the user can modify system files that normally cannot be altered and authorize third-party applications to do so.

Why Does A “New” Android Mobile Not Have Root Access?

Google does not want to offer a so-called “strainer” system. Logic. Imagine if a malicious application had root automatically, it would be able to cause significant damage to the system, only under normal conditions, by accessing sensitive parts of the system. Google has therefore preferred to opt for a system of conditions that is valid for all manufacturers who want to have the Google Play Store preinstalled in their product when it is on sale. If you didn’t know, mobile devices from the Google Nexus range (and Pixel, later now) are among those that are the easiest to root under Android.

What Are The Risks Of Rooting On Android?

Here we are talking about the risks associated with the procedure following the root. Indeed, we will “flash” a file dedicated to the source of the Android smartphone, as well as a custom recovery which will allow for enlarging the field of possibilities, if necessary. To access the heart, the developers exploit a flaw in the system. That is to say. A breach left open by the manufacturer or by Android that allows permanent access to system files at the root of the device.

Depending on Android versions, device model numbers, and other specific conditions, you should know that flashing a bad image may brick your Android device. More concretely, the term “brick an Android” is used when the mobile has become unusable following crap handling. Thus, it is then inert like a brick. If it is a “soft brick,” the blockage can be corrected by reinstalling the original system, while the “hard brick” means permanently blocking the device.

Does Root Invalidate The Warranty On Android?

This question is both simple and very complicated. Rooting does not void the warranty. Period. If you are not in metropolitan France, then it depends on the legislation of your country of residence. To take an example from Canada, rooting a smartphone on its soil voids the manufacturer’s warranty without notice. To return to the Old Continent, which declares that “the modification of the software part, including the root, does not in any way cancel the minimum guarantee of two years of the material part, which the manufacturer must provide to the buyer.” However, “if the manufacturer can prove that the root has damaged the hardware part, then the warranty is invalidated.” As it stands, we could think of overclocking, which can heat the processor to the point of “grilling” it. Still, evidence due to abnormal hardware wear and tear due to rooting, in this case, can sometimes take time to find.

How To Root Your Android Device?

We will answer this fateful question: it all depends on the smartphone model you want to root for. In a few words, let’s take stock of some general truths, well not so prevalent after all:

• Samsung mobiles are rooted using suitable software. Called Odin, it is available in different versions depending on the device: root Android: download Odin 1.85, 3.04, 3.07, 3.09 (all versions).
• HTC, Sony, and LG smartphones require unlocking the bootloader, according to official procedures, but which void the warranty. That being said, some methods allow rooting without unlocking the bootloader for certain devices.
• Nexus/Pixel smartphones are particularly easy to unlock, and the community surrounding them provides relatively simple and regular rooting methods with each new version of the OS.
• Chinese models are generally easy to root, but the relative rules related to confidentiality are sometimes a hindrance. As a result, community developers pay less attention to it.

Fortunately for other users, fewer geeks and some developers regularly offer small programs that grant root rights in one click or almost from Windows.

How To Root My Samsung, HTC, LG, Sony, And so forth.?

There is a wealth of information on the web, including tutorials and other practical aids. On our side, we also regularly publish a new tutorial targeting a fairly popular product. Whether on the blog or the forum, we offer many tutorials. If you have any doubts, do not hesitate to do a search or ask your questions. Before thinking about rooting, there are fundamental rules to follow: each time, it is important to check the Android version, the model number, and possibly other information such as the build number, etc.

This can, for example, prevent the mixed operation of modules with different working clocks: The entire main memory then works with the slowest module’s speeds (clock frequencies and timings). Otherwise, memory sticks with varying clock rates and from different manufacturers can be operated side by side without any problems, as long as they are of the same DDR standard and form factor. If you have used memory sticks that all work with the exact timings, you can check in the BIOS setup whether the computer is using the best possible settings for the RAM.

There are also special memories, especially for overclockers and gamers, which do not correspond to the RAM standards, which the standardization body JEDEC specifies because they use lower timings or faster clock rates. Here you usually have to set the best settings manually in the bios setup. There is another unique feature in the operating mode: the so-called dual-channel method is possible with at least two RAM bars, which doubles the theoretical data transfer rate of the main memory because the memory controller can address the modules of each channel at the same time.

The processor and motherboard must also support this technology, which is what all halfway up-to-date systems do. You must carefully insert the latches into the correct memory banks to use this mode. Mainboard manufacturers often help users label the appropriate RAM sockets in the same color. There is also the quad-channel mode, which can quadruple the transfer rates. However, this is currently only reserved for high-end CPUs and motherboards,

When selecting the RAM, you should always follow the technical specifications and know your system’s compatibility. Expensive RAMs usually have an aluminum heat sink to dissipate the generated waste heat. However, this is unnecessary since the main memory cannot heat up to the point of failure in regular, gaming, or productive operation as long as it sits in the normal airflow in the PC case. Additional air or even water cooling is therefore unnecessary. An exception here is systems that are to be overclocked.

Smartphone And Tablet: Upgrade Memory

Smartphones and tablets are small PCs in which so-called SOCs (Systems-on-a-Chip) provide computing power. Mobile devices also need RAM like a giant computer. And similar to a PC, RAM capacity limits the number of apps you can use simultaneously without slowing down the system. You usually notice this, for example, if you have not restarted the phone or tablet for a long time. However, the main memory in mobile devices cannot be expanded like in a PC since it is firmly soldered to the circuit board.

You must use tricks to ensure that the mobile device uses the available RAM effectively without overstimulating it. Mobile operating systems such as Android and iOS load the working memory in smartphones or tablets quite fully to save the user long waiting times when switching between apps. When the memory is complete, the system automatically takes action and closes applications that have not been used for a long time. That’s why third-party apps that promise better RAM management aren’t helping. Because after the cleaning, the system has to pack the required data back into the RAM, which entails a specific computing power and thus also affects the battery performance. Closing apps manually only makes sense if there are display errors or the application is frozen.

Android offers an overview in the settings to find out how much memory is still free and which app consumes the most RAM. From there, call up the “Apps” or “Applications” entry – the designation may differ depending on the user interface. Tap on the “Active” threshold to get the overview mentioned. Applications can also be terminated there. To clear RAM in iOS, press and hold the device’s sleep button until the power off slider appears. Then release the keys and hold the home button until the system redirects you back to the home screen.

Humming, crackling at the start and stop of an audio signal and miserable levels: the analog audio output of many onboard sound chips is barely good enough for video telephony and noisy video clips that you have filmed yourself.

The higher the quality of the headphones or the connected stereo system, the more noticeable the deficits of cheap sound chips. After installing a newer Windows version such as Windows 10 on older hardware, there is only crackling silence when the drivers for a sound chip do not work.

Headphones or the connected stereo system, the more noticeable the deficits of cheap sound chips. After installing a newer Windows version such as Windows 10 on older hardware, there is only crackling silence when the drivers for a sound chip do not work.

1. No sound: test the sound card and driver

If the audio output or the microphone input does not want to make a sound under a newly installed Windows system, this is often due to incorrect settings or driver problems that silence a PC. Even if the “Windows Audio” and “Windows Audio Endpoint Creation” services are not running, the sound output fails. With so many parameters, only a step-by-step sound check will limit the problem.

For Windows versions Vista and 7, Microsoft provides a fix-it tool for checking the sound card, driver, and possibly overlooked settings. To use the tool, go to the Microsoft website and then click on “Run now”. After the download, the diagnosis can begin.

The option “Identify problems and let me select the corrections to be applied” is recommended because this is the only way to determine the causes of the missing sound.

The tool first requires the specification of the output device, speakers or headphones. It then goes through all the typical sources of error: Manually switched off Windows services, deactivated audio device in the device manager to trivial or often overlooked settings such as output via the standard audio device, volume, and mute. You will then also receive a report on the problems found.

Starting with Windows 10, a proper diagnostic function is already available in the system, and a Microsoft tool no longer needs to be downloaded. In Windows 10, right-click the speaker icon in the system tray and select “Fix sound problems”.

Here it is also necessary to first specify headphones or loudspeakers as output devices. The further check is easy and shows the possible incorrect settings. Specify headphones or speakers as the output device. The additional review is easy and shows the possible incorrect settings.

2. Disturbing loops: Humming analog outputs

A widespread phenomenon when connecting the PC to the TV set or stereo system is a distinct hum in the background, which massively disrupts listening pleasure. This is independent of the quality of the audio equipment used, and changing the cables does not help.

The cause of the unpleasant background noise is a ground loop created by a potential difference between the protective conductor of the power supply or, in the case of TV and Hi-Fi devices, the antenna connection. The currents that flow across this potential difference are harmless.

However, they induce a typical, deep humming tone of the AC network in the audio cables carrying the signal via the standard ground line of the PC and audio device. This can be remedied by interrupting this loop via galvanic isolation. Cable does not help.

The cause of the unpleasant background noise is a ground loop created by a potential difference between the protective conductor of the power supply or, in the case of TV and Hi-Fi devices, the antenna connection.

The currents that flow over this potential difference are harmless. However, they induce a typical, deep humming tone of the AC network in the audio cables carrying the signal via the standard ground line of the PC and audio device. This can be remedied by interrupting this loop via galvanic isolation.

In most cases, a hum at home is due to an antenna or satellite cable on the TV or stereo. Therefore, do the test first, pull the antenna cable from the TV set, the receiver box, or the satellite receiver. If the audio signal sounds without a hum, you have found the culprit.

An electrical decoupling of the shielding of the antenna cable makes the dull background noise disappear. The easiest way to achieve this decoupling is to use a sheath flow filter.

As an intermediate piece, the interrupts the shielding (jacket) and the coaxial cable of the antenna or satellite cable with capacitors of a few nanofarads. You don’t need to use a soldering iron for this,

If the humming persists after disconnecting the antenna cable or if no devices with antenna connection are involved, the cause is found in the electrical installation: In old buildings without equipotential bonding between floors, for example, there is no uniform protective conductor for the electrical lines. In this case, currents between the ground lines of the hi-fi system and the computer connected to it could be responsible for the hum.

It can help connect all the relevant devices to a connector strip or separate the audio cables galvanically. Filters with cinch sockets, which filter out low frequencies, Galvanic separation of the audio cable. Filters with cinch sockets, which filter out low frequencies, are available for around 7 euros.

3. Digital: take sound via HDMI

If the device is connected to an output device such as a television via an HDMI cable, there are seldom deficiencies in audio quality. In addition to the video signal, HDMI also transmits sound directly digitally. The end device then takes over the conversion with its DAC. TV sets often deliver Hi-Fi quality and are superior to PCs.

If you connect headphones or a hi-fi system to the analog output of these end devices, the sound quality is correspondingly better. In addition to the video signal, HDMI also transmits the sound directly digitally. The end device then takes over the conversion with its DAC. TV sets often deliver Hi-Fi quality and are superior to PCs.

If you connect headphones or a hi-fi system to the analog output of these end devices, the sound quality is correspondingly better.

Instead of a TV set, you can also connect a splitter via HDMI, which only forwards the audio signal from the HDMI interface and makes it available digitally via SPDIF / Toslink and analog cinch outputs.

These HDMI splitters, such as the Ligawo HDMI decoder, are available from Amazon for 40 euros. HDMI, you can also connect a splitter instead of a TV set, which only forwards the audio signal of the HDMI interface and makes it available digitally via SPDIF / Toslink as well as via analog cinch outputs. These HDMI splitters, such as the Ligawo HDMI decoder, are

4. Upgrading: External sound cards and converters

Suppose the computer or notebook serves as a media center and delivers good audio quality for headphones, active speakers, or a high-quality hi-fi system without detours via HDMI.

In that case, it is worth investing in additional hardware: External sound cards with their own DAC ( Digital-to-analog converters) can also be connected via USB so that audio output and input are no longer left to an overwhelmed sound chip on the motherboard.

The effort for this solution is low because USB sound cards can be connected quickly, and capable converters are available for as little as 12 euros. Those who can spend more will, of course, get a better DAC.

As always, with hi-fi equipment, there are no upper limits in terms of acquisition costs. Suppose the computer or notebook also serves as a media center and delivers good audio quality for headphones, active speakers, or a high-quality hi-fi system without detours via HDMI.

The Speedlink Vigo USB adapter offers a cost-effective solution with the impressive sound quality for around 11 euros. The small device, which is hardly more significant than a WLAN adapter, contains a DAC and an ADC (analog-to-digital converter) for headphone output and microphone input – both in the standard 3.5 mm version.

Users who value excellent sound quality and a high-performance headphone amplifier get the Hires USB-DAC Saber 24/96 for around 50 euros, and at first glance inconspicuous but high-quality USB sound card with a 3.5 mm output. Headphone amplifiers value get with the Hires.
