Unlock the bootloader forcibly
-
Hi Stefano,
I know about the tutorial. I almost memorized it. The thing is with the Flyme 5 version of the os. I'm running Flyme 7 and the menu isn't giving me option to downgrade. When I factory-reset the phone I get Flyme 7 right away. Looking for Flyme 5 ROM on the Internet is like for looking for a living unicorn. And when you actually find it you need unlocked bootloader to load it into the phone.
I'm gonna give it another go. It's not like I have better things to do in this quarantine. -
@marek_python That's not true. You can download 5.1.3.0A and from your factory recovery on phone to wipe and ''update'' ( in our case it's a downgrade ) the Flyme to Flyme 5. No TWRP is required at this stage.
The recovery gives you only option to update, they never ment users to downgrade it. But it works both way, update and downgrade as well. I know, confusing. Give it a try. -
@marek_python Btw, there is no need for unlocked bootloader to downgrade to 5.1.3.0A, only later on, when you progress...
-
Yeah ... I managed to downgrade the phone to Flyme 5. But the phone doesn't like it. The phone is on but the screen is off. The screen is going on and off and nothing is on it. I recorded it. https://www.dropbox.com/s/81lbqpredxw4v2k/IMG_9191.MOV?dl=0

@marek_python Have you wipe the phone from the recovery, while applying ''update? Try again.
-
Yep, that was it. I wiped the phone and then downgraded. Now I'm gonna follow the tut and will report back. Thank you, Stefano, for your support.
-
@marek_python Good luck. Follow the giude.
-
Stefano, do you have by any chance the modified proinfo file ? The link in the tut (https://mega.nz/#!8ZJ01aZK!2WfKciJk1...EGua32_76hTBac) is broken.
-
@marek_python I'm out at the moment, will send you link later.
-
OK. Cheers.

Stefano, where should I dump the TWRP recovery image ? I left it on sdcard then I moved it into root directory but keep getting "error: cannot load TWRP_3.0_m86.img"
Where it should be located so it picks up on that ? -
@marek_python Need reboot to bootloader and from PC flash the recovery:
fastboot flash recovery TWRP_3.0_m86.img -
Yes, I know. I'm in fastboot mode and typed: fastboot flash recovery TWRP_3.0_m86.img but getting "error: cannot load TWRP_3.0_m86.img"
Hence I'm asking where it is looking for the file ?
-
@marek_python If I remember correctly you can go to the folder you have downloaded twrp to, open the terminal there then run the command.
-
@marek_python Need to go on your PC to right directory, e.g. if you have downloaded TWRP to Downloads, then go to Downloads. (cd /Downloads ) if you're using Linux, not sure about Windows or Mac
-
As turned out all I needed to do is to move the recovery file into
in Windows and rename it to recovery.img . That should be noted in the guide. The fastboot won't pick up on the image unless it's called recovery.img -

@Stefano Thanks a lot for the file !

@marek_python said in Unlock the bootloader forcibly:
(...) I followed the tuts on XDA site all UT community is aware of. However, I can't pass the point where I'm supposed to type "su" into terminal emulator. It just spits out "Connection to ui timed out" meaning it won't let me execute the commands where I need elevated privileges. And for overwriting the proinfo file I do need to be root in the session. So far I haven't found a way to go around it.
I had the same problem, Terminal just hangs. So I simply use
adb shell
suand a then following with the procedure (using simply cp instead of dd)
