Sir, I'm flashing system.img file to my micromax a27 via this command "fastboot flash system system.img" but it's showing error. Why? Pls help me immediately..

dont worry
No need to worry. Tell me are you flashing a kernel or an .ftf file or what?
By using fastboot, you will only be able to flash an .elf .sin or .img file!

1. extract boot.img and system.img for update.app using huawei update extractor
2. copy them into fastboot folder on your computer
3. go into fastboot mode and type this on you computer:
fastboot flash boot boot.img
&
fastboot flash system system.img
3. when completed just type "fastboot reboot"
4. wipe data and cache in recovery to start your phone like new
that`s what i do when i flash stock rom

Help! Mate 10 pro boot problem

Hi!
I have unlocked bootloader, then rooted and added twrp recovery, successfully without issues.

ive tried the viper4android uninnstaler provided in the same thred and still dosent boot.
i tried installing another dolby atmos with viper and a uninstaller, dont work either.
should factory reset fix it? it dosent in that case..
any ideas?

and it seems i cant take backup of the system to internal storage due to twrp bug,
ive tried backinguppon a 16gb usb3.0 device thru otg adapter with fat32 it stops at 3999 and backupp fails.
i tried otg to usb with 16gb microsdcard, also stopped at 3999 and failed.
i tried usb with ntfs but the it wont backupp at all.
what can i wipe?
installing stock a solution? how? flash update.app?(in zip).
custom rom?
is there any reason to lock the bootloader again?
Maximum file size of FAT32 is only 4GB per file. Use Huawei update extractor to get img files from update.app file. Flash those to your phone using fastboot. You can relock bootloader once you are in stock EMUI. Just run fastboot oem relock *your unlock code*.

ok thx^^ what files from the update.app? dont find any boot.img.
and recovery or recovery ramdisk.. dont really know what to write in that case
Extract system.img and ramdisk.img.
In fastboot, write:
fastboot flash system system.img
fastboot flash ramdisk ramdisk.img
Just rename you img files or use whatever name you like.
