I recently (dumbly) removed my internal through TWRP on my Asus Zenfone 2 whilst trying to flash SuperZen from xda. So now I'm attempting to go back to stock, and I've tried doing a factory reset with the stock recovery, but with no luck. I'm currently trying to flash boot.img
, recovery.img
, droidboot.img
and system.img
via fastboot
on Linux and Windows, but I get:
$ fastboot flash system system.img
target reported max download size of 536870912 bytes
erasing 'system'...
FAILED (remote: Permission denied)
finished. total time: 0.136s
for each one. This is when trying to flash using version WW_2.19.40.22. The interesting thing is, is that when I flash twrp.img
or recovery.img
(stock) it still gives me that same error, but when I boot into recovery, I have either TWRP or stock recovery, which shows that it did work. Sadly, this is not the case with system, so if I reboot into the system, it does not work properly and hangs on the "Powered by Android" splash screen.
EDIT:
just tried using fastboot update -w Zip_Name.zip
and it gives me:
archive does not contain 'android-info.txt'
archive does not contain 'android-product.txt'
error: update package has no android-info.txt or android-product.txt
EDIT 2: booted into TWRP and used "Install" to try and flash the .zip I put on the SD card, I got the logs copied to the SD, and here is the relevant section:
minzip: Missed a central dir sig (at 0)
E:Zip file is corrupt!
MtpServer::run fd: 13
E:request read returned -1, errno: 5, exiting MtpServer::run loop
Error flashing zip '/external_sd/UL-Z00A-JP-2.19.40.21-user.zip'
Updating partition details...
I:Data backup size is 0MB, free: 55424MB.
...done
Basically, it gave me E:Zip file is corrupt!
and ended up with "Failed".
