hi, i have the same prob. i tried your way, push rom to sdcard folder and flash itCould I ask for a little bit of help, please
I have installed TWRP. I then copied the 12.5.7 Rom to the phone and installed it. I went to reboot and it said 'are you sure - no os installed'. Lo and behold, I rebooted and it came back to TWRP.
I can't reinstall the ROM as I can't transfer the zip back to the phone (as the phone doesn't appear in windows as a storage device, even if I mount it in TWRP).
Am I missing something?!
Thanks in advance
PS TWRP still works fine
Edit: solved somehow! I used adb push to re-transfer the rom to the sdcard folder. Then wiped the caches. It gave me a number of errors when reinstalling the rom but seems to have worked
Then choose wipe cache, but phone still reboot to recovery. wth is wrong with this twrp
