My phone is Sony Z5 Compact Nougat.
What I had done is as below:
- Unlock Bootloader
Use the following command to flash twrp recovery
fastboot boot recovery.img fastboot flash recovery recovery.img fastboot flash boot boot.imgThe file are from this link : https://forum.xda-developers.com/z5-compact/orig-development/twrp-z5-compact-t3235161
Version of twrp : 184.108.40.206
Wipe > swipe and factory reset.
So now when I try to reboot, it says
No OS Installed! Are you sure you wish to reboot?
I tried to flash both Paranoid Android (Official) and Carbon Rom (Unofficial) both in the format of .zip and it show me below error message:
mount: failed to mount /dev/block/bootdevice/by-name/system at /system: No such file or directory unmount of system /system failed: no such volumeTried few times but same problem
I then also tried Advance > ADB Sideload, my command are as below
adb sideload carbon.zip adb sideload paranoid.zipThe error message is also the same as above
As far as I concern I cannot find twrp version that are above 3.0 for this device, and now I cannot boot into any os as there are no os that I can boot into, hence cannot perform the step for recovering stock rom .ftf using flashtool, what should I do in order to get back to at least stock Rom or any way to fix the failed to mount problem, which I suspect it is because of the old version of TWRP.
Additional : I am very sure that my firmware version is the latest version.
