- Back to your computer. Copy all the files that are in AdbFastbootTool to the Folder ROM that you downloaded and extract
- To flashing we run CMD.exe, here I have attached cmd-32bitPC.exe (for Windows OS 32bit / x86) and cmd-64bitPC.exe (For Windows OS 64bit / x64 computers), please select it according to your computer.
Note: If the cmd.exe that I attach does not work, Other ways are:
1) Go to the Rom folder > press SHIFT + RIGHT CLICK button on the computer, then select open command windows here.
2) Open (Start window), search cmd.exe and than copy to the Rom folder
- After CMD.exe is run, then now we will transfer one by one partition files from the computer to your phone by typing each command and continuing with ENTER BUTTON.
- For example i will install just recovery.img or boot.img, Then the command I will type is: fastboot flash recovery recovery.img or fastboot flash boot boot.imgNote: We can know where each file is going to be transferred to your devices via flashfile.xml (Motorola devices) or rawprogram0.xml (Qualcomm chips), MTxxx_android_scatter.txt (Mediatek chips), But basically every android devices will be the same.
- By reading flashfile.xml or rawprogram.xml then we should not experience errors in flashing, either one by one or full firmware. For example I did it on Motorola and Xiaomi. Note: each command ends with ENTER.
- Example: Flashing Motorola Firmware by Flashfile.xml
- Example: Flashing Xiaomi base on qualcomm chips Firmware by rawprogram0.xml
