adb reboot bootloader- Check if connected to fastboot
fastboot devices- Unlock bootloader
fastboot oem unlockAfter entering, use the phone's volume up and down keys to select in the subsequent interface, and use the power button to confirm the unlock was successful. (This will erase phone data and restart.)
Step 4: Flash Recovery, ROM#
Preparation#
- Download the ROM package, extract
payload.bin, and use the Fastboot Enhance tool downloaded above to extractdtbo.img,vbmeta.img,vbmeta_system.img,recovery.img, andboot.imgfiles frompayload.bin. - Extract and open the ADB toolbox folder downloaded above, and enter the platform-tools directory.
- Place the extracted img files and the downloaded ROM zip package into platform-tools.
- In the address bar of the file explorer, type cmd and press Enter to open the command line (this operation opens the command line in the current directory to resolve issues where certain driver versions do not have related commands).
Flash Recovery#
With the phone powered on, enter adb reboot bootloader to enter fastboot mode;
In the just opened cmd window, run the following commands in order to disable AVB verification1 and flash recovery and dtbo.
- Flash boot
fastboot flash boot boot.img
- Disable VAB (if the ROM official tutorial provides a vbmeta image, you can directly fastboot flash
vbmeta vbmeta.img to flash the provided image)
- If flashing the official image provided by the ROM cannot disable vba verification, it is recommended to extract the vbmeta image from the OTA package of your phone's system.
fastboot flash --disable-verity --disable-verification vbmeta vbmeta.img
fastboot flash --disable-verity --disable-verification vbmeta_system vbmeta_system.img
- Flash dtbo
fastboot flash dtbo dtbo.img
- Flash recovery (the image can be from ROM unpacking or provided by the official tutorial)
fastboot flash recovery recovery.img
After successful flashing, use the phone's volume up and down keys to select recovery mode and then press the power button to confirm the reboot into recovery.
Flash ROM#
In Recovery, select (you can use volume + - to select and power to confirm or touch screen) Apply Update → Apply from ADB to enter ADB sideload;
In the computer cmd, enter the following command and press Enter to flash (if the ROM you flashed already contains the related images, this operation is not necessary)
adb sideload [drag the AB partition unified package or firmware package directly into the cmd window]
If the path contains Chinese or special characters, you need to wrap the path with Western quotes, as shown below:
adb sideload "D:\Downloads\ExampleROMFile.zip"
If you encounter issues where using Windows PowerShell or CMD to drag files does not generate a path, you can directly enter the file path (if the path contains Chinese, please wrap it with English double quotes or single quotes, generally the format is adb sideload "E:\adb fastboot tools\recovery.img").
Usually, ADB will report the following, and these can all normally start and reboot.
(Be sure to double wipe)
Stops at 47% and reports
Total xfer: 1.00x
adb: failed to read command: Success
In some cases, it may also report
adb: failed to read command: No error
adb: failed to read command: Undefined error: 0
In some cases, you may not be able to boot normally. In this case, you can try using the Fastboot Enhance Tool downloaded above to flash the payload.bin file from the ROM package, with similar effects.
If the problem persists, please confirm whether the base package you flashed is correct and whether AVB verification is disabled;⌛ Praying for the girl...
