[TUTORIAL] How to unpack Android ROMs on Windows

[maff1989]

i wana extract boot.img , but i have some error

CAN'T UNZIP A BOOT.IMG!! Either unyaffs or "mount -o loop boot.img /mnt/*folder*"

To unmount, "umount /mnt/*folder*"

Obviously not windows commands

Would anyone know how to transfer the /data back to the phone?

Someone once told me you can just run the .exe file, let it open, use windows to search for the rom.zip that would have been extracted into a temp folder, drag&drop to another location, then cancel the .exe again.

This works. I did it with the pico sense 3.5 rom

yes you run the ruu.exe ( example: RUU_Bravo_Froyo_Vodafone_UK_2.33.161.2_Radio_32.49.00.32U_5.11.05.27_release_157522_signed.exe)

then in windows explore type %TEMP% press enter

look in {D0CA1E30-2DED-4C58-BB4A-E4F87AA2DB27} yours might be diffrent

then in {50F2F878-636A-496F-A7CB-544C067E0C4B} your may be diffrent

then right click rom.zip and copy to another folder somewhere ( may be large as 1 GIG size

right click rom.zip and use 7-zip and select Extract to rom

then I use either ext2explore or unyaff ( which ever one works)to unpack system.img

How to extract ROM_0 ? without the phone

Can you please help me , i readed back my ROM using "SP Flash Tool" , but i forget to extract it with "MTKDroid"
and i know that the program wouldn't extract the file except he reads my tablet "MT6577" (Unknown model and type).
And my mistake was i flashed a wrong ROM to my tablet and it's now half bricked , but "MTKDroid" won't read it and won't decompress the backup (ROM_0) , is there is any program could extract the file ?
