[Guide] Convert to Global [WIP]

[VRtualVortex]

I'm having problems. I follow the exact instructions.

MSM, unlock bootloader, and then flash-all.

It works fine for about 50 seconds, until the phone reboots into fastbootd.

My CMD prompt stays on "<waiting for device...>", even though i am in fastbootd. All that's on the screen is 3 languages, and "fastbootd" at the top. What should I be doing?

Anyone get this error?

Qualcomm CrashDump Mode Attempted to kill init! exit code=0x0000000b do_exit

 

[GrandMstrBud]

So I used the MSM tool to restore and while it's unlocked now the OEM unlock is greyed out.

Did a factory reset and it came back and now in luck and flashed it again and this time it worked.

Man.... I give up... tried a couple times and it either gives me crash dump error or not allowed because of critical partition. I have an IN2017 Tmobile phone btw.

Critical partions must be flashed in fastbootd or edl. Fastboot reboot fastboot gets you there. Or from adb ,adb reboot edl

I'm having trouble with my OnePlus 8 T-Mobile phone I'm trying to change it to the global firmware but it isn't working like after i run the flash all bat file and let it do it's thing it goes to recovery mode waiting for and any devices as soon as i press reboot to fastboot the commands fail as in it tries then quits and i doing something wrong

Can someone help me? I am on a Tmobile device. I want to flash to global firmware, and lose things like the tmobile boot screen. I did it before, (then subsequently switched to latest paranoid android rom) I just dont remember how., or what I did. it seems I did what im doing now and just didnt get the crashdump mode. Everytime i flash global firmware with the flash-all.bat file, i get qualcoomm crashdump mode and it gets tiring having to unbrick. After flashing, it seems i lose access to everything and the only thing i can do is use the unbrick tool... id like to be back on global...

thanks

EDIT: NEVERMIND , I GOT IT. used msm to get on 10.5.7 then flashed to 10.5.9 ... now back to 11.

THANK YOU

In my TMobile OnePlus 8-5G Developer Options, I have 'OEM Unlocking' enabled. How to get the unlock token?

When you ran the flash all bat file for 10.5.7 then the phone goes into recovery mode what do you do because nothing happens when I do it it stays in recovery mode it would be really nice if you could answer that

That's not recovery that's one plus edl mode. What it has to be in to flash system dtbo, critical partions.

Then how long does it take to be on the screen with English because it kept saying waiting for devices even after 2-3 minutes

After the flash all.bat kicks it to edl it flashes the remaining partions then is done. You wipe date/ factory reset then reboot.

I thought I had to reboot to fastboot after pressing English in that menu I think I'll try it again

that didn't work it went to the T-Mobile boot logo is it possible you can upload a video on what you did? the only video on youtube doesn't really show a good example i don't know

 

[arielaffy]

No one has made a video explaining well with the required files? with everything I read here I even got lost. I have the unlock token and the phone unlocked. And that every time you update you have to install the modem again?

 

[samdaman91]

Does anybody have step by step instructions for a novice person?

No, you don't need to install the modem, the international modem works just fine. Once your device is sim unlocked AND bootloader unlocked: use MSM to flash back to 10.5.7, unlock bootloader again, flash Twrp, back up Persist.img and modem.img. Transfer those files to your computer. Then update to 10.5.9 via OTA, then you're good to convert through fastboot. I backed up persist.img and modem.img, but never ended up needing either. That being said, take the extra 20 minutes and back them up before you convert. Might end up saving your phone a trip to China!

Did you register your fingerprint before MSM?

 

[arielaffy]

Now I have the same problem as some, that when the global installation starts and the phone restarts for the recovery mode, it does not happen from there the program keeps saying waiting for device. It does nothing more from there

 

[arielaffy]

In the end I was able to get it and I am already in the global version. Everything working perfectly
