Why flashing "Android"?Because of the desire to expand the functionality, see how your gadget can look like in a new “wrapper”, restore the phone when there is no opportunity to roll back, etc. But regardless of the reason, it is done so.
How to install the firmware on the "Android" from a computer?
Сначала нужно её скачать.It is best to download the official from the site of the manufacturer of the mobile device. It is worth noting that the software is selected directly for a particular phone model, otherwise it may not “become”, which may cause additional problems.
If there is no manufacturer’s official websitethe necessary software or it does not suit something, you can go to the World Wide Web and search for custom. Custom (custom) firmware - an operating system from an unofficial developer, which has some improvements, bug fixes and bugs, and can even increase the battery capacity. That's just to look for it you need only on safe sites, and before downloading, be sure to familiarize yourself with the features and features, view screenshots, read reviews from other users.
Need to know
Before flashing a mobile device, you need to remember and follow a few rules:
- It is necessary that the battery charge of the phone is at least 80%, and better all 100%.
- Install drivers on your computer for your device.
- It is very undesirable if the firmware "Android" throughThe PC will terminate due to power outages. Therefore, it is best to use a laptop or a stationary computer with an uninterrupted power source in this matter.
- To protect your device from low-quality OS, you need to make a backup copy of the current software and data.
- It is highly undesirable to use USB 3.0 port when flashing (USB 3.0 port is blue, 2.0 is white).
- Once again, before downloading the firmware, you must carefully read it. Also avoid suspicious sites.
- It is best to use the original USB cable that came with the device.
- Usually, after flashing, the device power button must be held for 15-20 seconds, so do not panic if it turns on for a long time. Then it will turn on, as before.
Fastboot
Firmware is available using Fastboot"Android" through the computer. Download the Fastboot utility, unpack it to the root of the system disk (most often it is drive C). It turned out the folder with the path to it C: Android. There are 2 more folders: Tools and Drivers. The first one contains the necessary programs, the second one contains the drivers. Open the Drivers folder and install the necessary drivers. Next, in the Tools folder we transfer the downloaded firmware in a zip archive. Now we connect the gadget to the computer via USB.
Open the command line (or cmd) and enter the command without quotes "cd C: AndroidTools". Moving to the directory of this folder, enter fastboot devices.
In this case, the device code should appear. If the code does not appear, then you need to unlock the bootloader.
Bootloader gives the OS information about the status of the cardmemory, RAM, kernel and is responsible for loading the OS. And if it is not unblocked, the flashing will fail. It is worth noting that when unlocking the bootloader, the device loses the warranty. However, it is quite easy to block it back if the need arises. You need to pay attention to the fact that unlocking will erase all the contents of the device and the memory card, so the best thing to do is to back up the data of the internal memory and the SD card.
Unlock the bootloader
To unlock the bootloader (and the firmware of the Android tablet via a computer is made possible), you need to perform the following steps:
- Turning off the mobile device.
- We connect it to the PC and simultaneously hold down the power button and both volumes.
- On the computer, open the command line (or cmd), where we enter “cd C: AndroidTools” without quotes.
- Enter the command fastboot oem unlock.
- Check again with the fastboot devices command.
- If instead of the gadget code appeared waiting for device, you should check for the presence of drivers and change the USB cable.
If the device was identified, enter the command: fastboot update filename_zip.zip. After flashing we reboot.
Flashtool
Перед тем как установить прошивку на «Андроид» с a computer using the Flashtool utility, you need to download an operating system in ftf format. After downloading and installing the program. The downloaded file for flashing is placed in the folder Firmwares, which is located in the program directory. Run the utility.
Click on the button with a lightning bolt in the upper left corner, leave a point on the Flashmode.
Now you need an operating system file from the listfor a gadget, on the right there should be ticks on Wipe User Data and Wipe Cache. We are waiting for a bit, after which a window will appear with instructions for connecting the phone. We connect it to the computer and simultaneously hold the power button and the volume down (camera, menu - the key combination can be different for different phones, so you need to clarify for a particular model). As soon as the program gains access, the phone will automatically flash through the computer. "Android" will be installed quite quickly, within a few minutes.
After the process is completed, turn on the gadget and go through the initial configuration.
This method of software installation is one of the best, since you can install the firmware on the “Android” from a computer using Flashtool when the phone is turned off, which does not have a Recovery mode.
With the help of specialized programs
Many mobile device developersdeveloped special service utilities. One of these utilities is the Fly software update. With its help, it became possible to update the current OS and firmware "Android" through the computer Fly-smartphone.
Download it, install it.Once installed, the utility will offer to connect the device to the PC. It should be noted that USB debugging on it must be enabled. If it is disabled, the utility itself will help to do this. After that click "Install Driver".
Connect the smartphone, run the utility.Click "Check for Update" and select a model from the list (if it was not determined itself). Next, a window will appear with information about the software, where we click "Start Download" and follow the simple instructions.
Such a program is far from being the only one, as it is possible to install the firmware on the “Android” from a computer using such a utility from a developer on almost every smartphone.
Recovery mode
In "Recover" mode, that is, inrecovery, you can also flash your device. As in any other case, you need to download the OS and move it to the SD card. It is worth noting that this firmware is produced "Android" without a computer.
In order to install a new OS onPhone, you need to go to the engineering menu or Recovery mode. To do this, turn it off, and then simultaneously hold down the power button and the volume down, up, or the menu button (for each phone manufacturer, the combination may be different, so you need to find out further).
Depending on the version of "recovery", our actions are as follows:
- in the standard version, click apply update from external storage;
- in version TWRP - install ZIP;
- CWM version - apply update from sdcard.
After the firmware "Android" HTC or any other manufacturer is successful, you need to restart the smartphone and go through the initial configuration.
It should be noted that if there wereall possible combinations have been tried, and the gadget has not entered the “recovery” mode, which means that this function is disabled or absent in this device.
A couple of words
Once again we recall a couple of important points that can save several thousand nerve cells from certain death:
- Before installing the firmware on "Android" withcomputer, be sure to make a backup copy of the data. This can be done with the help of special utilities from both the official developer and the unofficial one. This will help to make a system recovery if the flashing failed.
- After flashing to hold the power button you need 15-20 seconds. If the inclusion did not happen, you can try to remove and insert the battery and try to make the inclusion again.
- Rather, the flash card will have to be formatted.Even if there is a lot of information there, the new Android can create new sections on it over the old ones, completely ignoring the latter. Therefore, before connecting the USB flash drive, it is best to reset all its contents to the computer.
