What about this video, just flashing the rom with fastboot without backup persist and modem, with out MSM or custom recovery and root?

Im very confused with all of this, i dont know if i need to use MSM or just flash with fastboot, or backup persist and modem :(
[OnePlus 8 Guides, News, & Discussion] brain_72:
hi, i have the T-Mobile 10.5.10,im waitting the unlock code for the bootloader, do i need to downgrade to 10.5.7??? i dont understand what is the point. thanks
[OnePlus 8 Guides, News, & Discussion] Hammerhand.17:
And how can you chek if it worked? I have gone through the guide with an 8 pro and it still is marked as "in2020" (chinese version), although in firmware information I can see the "11BA" mark; is it right, or should I see "in2023"?

Thanks!
[OnePlus 8 Guides, News, & Discussion] TheKnux:
So I converted my OP8 to global a few months ago, and after having to MSM a few times, I finally got it. However, my girlfriend also has a OP8 and for some reason I can't get hers to convert. When I use a fastboot ROM, when it reboots to fastboot after using the flashall, it enters Crash Dump mode. Then I have to MSM back to stock. I tried entering fastbootd, but for some reason when I enter the command "adb reboot fastboot" it enters normal fastboot. When I do it on my already converted OP8, it enters fastbootd. I tried all of the possible commands and it still ends up in Crash Dump mode. Any pointers? I can provide more info if needed, this was just the gist.
[OnePlus 8 Guides, News, & Discussion] brain_72:
even with the modem back up. and restore, i dont have signal :/
[OnePlus 8 Guides, News, & Discussion] BIGWORM:
So I used to the flash_all on my TMO 8T, but from what I can tell, I think I'm still on the TMO variant. Should I try again?
[OnePlus 8 Guides, News, & Discussion] dj41490:
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.
[OnePlus 8 Guides, News, & Discussion] castle200:
I did everything correct as far I know. Backed up persist, backed up the modem, flash_all to android 10 and OTA to android 11... Only issues I have so far is that Google Pay and Netflix don't work on the phone anymore. Is there a work around for that? I'm not rooted but the bootloader is still unlocked. I would hate to lock it again as I know that's not a good thing to do in most cases. I was hoping the OTA would do that but it didn't
[OnePlus 8 Guides, News, & Discussion] xxBrun0xx:
The issue is that your bootloader is still unlocked so you're failing safetynet (which apps like netflix and banking apps check). Flash a rooted boot.img (to install magisk), open magisk manager app, and enable Magisk Hide and you'll be all set.
[OnePlus 8 Guides, News, & Discussion] papoose515:
does this unlock my oneplus 8?
[OnePlus 8 Guides, News, & Discussion] castle200:
Yep, that's what I have
[OnePlus 8 Guides, News, & Discussion] papoose515:
even if its on a bad esn?
[OnePlus 8 Guides, News, & Discussion] 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?
[OnePlus 8 Guides, News, & Discussion] GrandMstrBud:
Anyone get this error?

Qualcomm CrashDump Mode Attempted to kill init! exit code=0x0000000b do_exit
[OnePlus 8 Guides, News, & Discussion] GrandMstrBud:
So I used the MSM tool to restore and while it's unlocked now the OEM unlock is greyed out.
[OnePlus 8 Guides, News, & Discussion] GrandMstrBud:
Did a factory reset and it came back and now in luck and flashed it again and this time it worked.
[OnePlus 8 Guides, News, & Discussion] mattie_49:
Critical partions must be flashed in fastbootd or edl. Fastboot reboot fastboot gets you there. Or from adb ,adb reboot edl
[OnePlus 8 Guides, News, & Discussion] ThatmanwithaDream:
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
[OnePlus 8 Guides, News, & Discussion] satva49721:
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
[OnePlus 8 Guides, News, & Discussion] sjgoel:
In my TMobile OnePlus 8-5G Developer Options, I have 'OEM Unlocking' enabled. How to get the unlock token?
[OnePlus 8 Guides, News, & Discussion] ThatmanwithaDream:
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
[OnePlus 8 Guides, News, & Discussion] mattie_49:
That's not recovery that's one plus edl mode. What it has to be in to flash system dtbo, critical partions.
[OnePlus 8 Guides, News, & Discussion] ThatmanwithaDream:
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
[OnePlus 8 Guides, News, & Discussion] mattie_49:
After the flash all.bat kicks it to edl it flashes the remaining partions then is done. You wipe date/ factory reset then reboot.
[OnePlus 8 Guides, News, & Discussion] ThatmanwithaDream:
I thought I had to reboot to fastboot after pressing English in that menu I think I'll try it again
[OnePlus 8 Guides, News, & Discussion] ThatmanwithaDream:
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
[OnePlus 8 Guides, News, & Discussion] 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?
[OnePlus 8 Guides, News, & Discussion] samdaman91:
Does anybody have step by step instructions for a novice person?
[OnePlus 8 Guides, News, & Discussion] xxBrun0xx:
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!
[OnePlus 8 Guides, News, & Discussion] garypix:
Did you register your fingerprint before MSM?
[OnePlus 8 Guides, News, & Discussion] 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
[OnePlus 8 Guides, News, & Discussion] arielaffy:
In the end I was able to get it and I am already in the global version. Everything working perfectly
[OnePlus 8 Guides, News, & Discussion] demonlordoftheround:
What did you do that was different to make it work? Asking for others who have this problem.
[OnePlus 8 Guides, News, & Discussion] garypix:
What was it that made it work? Do you mind sharing? I'm about to do the same.
[OnePlus 8 Guides, News, & Discussion] arielaffy:
Use the MSM for 10.5.7 then reinstall the drivers that oneplus offers you when you connect the phone to the pc. I did the whole process again of unlocking the bootloader. After that I did the installation of the global software and it was installed without giving me any problem. Lock the bootloader again and update via ota to Oxygen 11

The fingerprint and the signal works. perfectly and I did not backup any of that.
[OnePlus 8 Guides, News, & Discussion] garypix:
Thanks! Do you mind sharing the link to the drivers? Also, did you take any OTA updates after you MSM to 10.5.7 (i.e.:10.5.10)?
[OnePlus 8 Guides, News, & Discussion] tuntun2526:

How did you update to 10.5.9 via OTA? Already on 10.5.7 Tmob firmware, backed up img files... When I go to the system updates goes directly to 10.5.23...
[OnePlus 8 Guides, News, & Discussion] JoeOtterson:
What did you do to make it work? I'm still sitting on the waiting for device screen in the flasher and fastbootd on phone
[OnePlus 8 Guides, News, & Discussion] danielofata:

3. Flash unlock code.bin

4. Fastboot oem unlock

5. Repeat step 2

6. flash-all.bat international firmware (like 5 different versions)

[OnePlus 8 Guides, News, & Discussion] sjgoel:
I will be taking the plunge over the weekend. What is the best way to backup & bypass the trip to China?
[OnePlus 8 Guides, News, & Discussion] Ostrich Egg:
Worked perfectly for me, thanks!

1. Used MSM to downgrade to 10.5.7

2. Unlocked bootloader

3. Flashed 10.5.21 international with fastboot/flash-all

4. Upgraded to 11.0.0 via OTA

5. Found out there's no TWRP for 11 yet so sitting here unrooted 🥴
[OnePlus 8 Guides, News, & Discussion] garypix:
Thanks for sharing. Did you need to install any drivers before MSM? Also, which drivers did you use for fastboot? TIA!
[OnePlus 8 Guides, News, & Discussion] Ostrich Egg:
No drivers before fastboot. Windows detected fine. Later, I did install the OnePlus drivers included with the phone and it still worked fine.

For MSM, I had to manually force the device to use the Qualcomm driver rather than the detected Quectel driver. I don't think this came from any drivers I installed, but I could be wrong:
[OnePlus 8 Guides, News, & Discussion] xxBrun0xx:
Just a heads up, you can definitely root android 11 without Twrp by flashing a rooted boot.img in fastboot. I'm sure there's a thread on it in the forums, but if not I can send you that pre-rooted boot.img.
[OnePlus 8 Guides, News, & Discussion] Ostrich Egg:
Thanks! Didn't realize Magisk could do that now. Got the boot.img patched and installed.
[OnePlus 8 Guides, News, & Discussion] lordcheeto03:
I figure this may be as good a thread to ask this question in as any... I've apparently messed up my slot b... As in even after using the msm tool and taking the OTA, if I attempt to boot system or recovery from slot b I go straight to crash dump mode... I can still boot into fastboot and edl while on slot b. From fastboot I can use "fastboot boot <twrp.img>" and get to TWRP that way while still on slot b, but that's it.

My question is this: is it safe to modify each entry in the flashall.bat in the global fastboot firmware from the standard "fastboot flash <partition> <file.img>" to "fastboot flash <partition_b> <file.img>"?

Will this likely have the desired effect? Are there any partitions in the flashall.bat that maybe don't get flashed to slot b?
[OnePlus 8 Guides, News, & Discussion] garypix:
Thanks for all the help on this thread. I got my unlock bin file from OnePlus yesterday and was able to unlock the bootloader on my TMO OP8. Here's what I did to convert my TMO OP8 to global version:

1. signed out of all services and deleted all fingerprints on the phone before unlocking bootloader, unlock bootloader using Fastboot

2. MSM to TMO 10.5.20 (had some issues with the driver but ultimately got it working)

3. Unlocked bootloader again using the unlock bin file

4. Flashed 10.5.12 international using a PC and the flash-all command (be patient, it takes a while)

5. Upgraded to 11.0.2.2 International via OTA

6. Relocked bootloader to get Netflix working again

No root, no TWRP - as I use this phone for work and there's no need to tinker.

No issues with fingerprint, I didn't backup persist, YMMV.
[OnePlus 8 Guides, News, & Discussion] danielofata:
Dude, at step 4 during the process phone reboots to "recovery" and CMD is stuck on < waiting for any deice > before I hit the flash all i checked bootloader status and idk why tF critical unlocked is set to false, can you please help me?

< waiting for any device >

[OnePlus 8 Guides, News, & Discussion] Danny1976:
Just bought a OP 8 and speakers sound like crackling distorted. I Just converted from TMO to Global as soon as I received the unlock token. Anyone know if its a software issue or that maybe the speakers are blown. Its both speakers, but mostly the bottom one. I tried cleaning both speakers with 91% alcohol solution and a brush, but I still get bad sound.

Phone was bootloader locked and sim locked when I received it. I got the sim unlocked and unlocked the bootloader. If the speaker are blown.... How can that be done without any audio mods, since the software has a protection to prevent that?

I was thinking maybe it was a software issue after the converstion to global. I really didnt test the phone on stock rom, because I wanted to get it unlocked and I knew it was going to delete all my data.

Update:

Seems to be that the speakers are blown. Requested a repair service from OnePlus under warranty.
[OnePlus 8 Guides, News, & Discussion] lukeasch21:
Now that t-mobile is providing an official Android 11 update, is it possible to copy the modem over and have SA work on international?
[OnePlus 8 Guides, News, & Discussion] uNdea:
It's not necessary to backup Modem. I did backup persist.img just in case, but never needed. YMMV so do on your own risk. It only takes extra 5 minutes, so better backup for safety.

Had 2 devices and converted both to Global without any complications. After I flashed Global ROM, had no cell reception but once phone installed latest OTA, all works normally. Fingerprint worked right away after conversion.

This is what I did:

1. Unlock bootloader (2 phones - on oxygen 10.5.20 and 10.5.23)

2. fastboot boot TWRP, install magisk and backup persist.img (Not necessary)

3. MSM to 10.5.7

4. Unlock bootloader again

5. Fastboot flash Global 10.5.12 (At first try one phone was stuck at some point, on "Sending 'boot'" message. Just restarted phone and tried again, worked second time)

6. Get OTA to android 11

7. Re-Lock bootloader
[OnePlus 8 Guides, News, & Discussion] uNdea:
Is there any way to enable Dual-sim support? 4G both sim cards.

I had 6T converted to dual sim like this, then 7T, is it possible for oneplus 8 ?
[OnePlus 8 Guides, News, & Discussion] lukeasch21:
Thanks for the guide! Have you tested to see if you have 5G SA support on global?
[OnePlus 8 Guides, News, & Discussion] mattie_49:
Please don't tell people not necessary to back up persist. It is very necessary and you can't use just any old persist if you loose. I've been flashing for many years on many different devices and since unlock in November on my op8 ;of last year ,I've lost persist from making one simple mistake.Glad I had the sense to back up first. So a simple restore could fix.
[OnePlus 8 Guides, News, & Discussion] lukeasch21:
You're 100% right @mattie_49 , I've nearly had to throw away a phone I've had when I forgot to back up persist. By any chance do you know if the A11 modem from T-Mobile will work on global? I just scraped the ota (hopefully not incremental?) And was about to extract the modem from it. If you don't know, what would be the worst outcome in case I flash the modem and it doesn't work?
[OnePlus 8 Guides, News, & Discussion] mattie_49:
I believe the t- mobile variant does indeed work on global. However Verizon does not. Worse case scenario break data and have to msm back to stock. And relock bl
[OnePlus 8 Guides, News, & Discussion] uNdea:
@mattie_49

Okay, I did edit my post. It's just extra 5 minutes work, so better backup
[OnePlus 8 Guides, News, & Discussion] sjgoel:
I have a T-Mobile OP8 now on global A11, and I want to flash A11 TMO modem. But I have no idea how to extract it. Any pointers. Thanks.
[OnePlus 8 Guides, News, & Discussion] mattie_49:
Use this app. If your on global you will have to msm back to stock ,unlock,root and use this app to backup modem. Saves partion to your sd card. Works nicely. Go into settings of app and tic raw image file not compressed before backing up. Send to cloud,download and flash through fastbootd.

Back up your persist img as well for sure before messing with anything. This app backs it all up.

[OnePlus 8 Guides, News, & Discussion] sjgoel:
Thanks. Since TMO has released the A11 update, I think I use that to return to stock, and then carry out the process above.
[OnePlus 8 Guides, News, & Discussion] lukeasch21:
Alternatively, there are command line tools to extract the payload from the full ota. I have done all the dirty work and have a copy of the t-mobile android 11 modem img. I have yet to test so if someone wants to report back that would be great. (link here)
[OnePlus 8 Guides, News, & Discussion] mattie_49:
What command lines are there to extract payload ? I tried running logcat to snag a download link but didn't work. I'm on Verizon with an op8. Any help would be great as using msm readback is quite confusing on what to pull. Verizon updated the 27th to a11 finally. I know it has to be done during ota
[OnePlus 8 Guides, News, & Discussion] anonymoustl:
Does this work for the Verizon model? Or will one of the custom rims work on the Verizon model?
[OnePlus 8 Guides, News, & Discussion] mattie_49:
It will work but can't local upgrade or it breaks data. just don't flash modem, flash system, vendor, dtbo, boot, odm, vbmeta, vbmeta_system and recovery. Boot to recovery after,wipe data/factory reset . It should boot right up. And of course if your on A10 flash a10 global on Verizon's newest A11 flash global a11. Hope this helps. And this is a global thread and converting so; mentioning other roms is probably frowned on. At least in this thread
[OnePlus 8 Guides, News, & Discussion] anonymoustl:
Awesome. Thanks.
[OnePlus 8 Guides, News, & Discussion] mattie_49:
Currently no. Global gets rid of bloatware. All the other A11 roms other than PA don't have working data for us yet. And much has changed, I'm an ol timer and all this was new to me in Nov when I finally got unlocked.
[OnePlus 8 Guides, News, & Discussion] sjgoel:
--deleted--
[OnePlus 8 Guides, News, & Discussion] mattie_49:
Doesn't work to well to restore partions but backs them up great; fastboot and fastbootd do however restore perfectly.
[OnePlus 8 Guides, News, & Discussion] mattie_49:
Since me posting this I tried flashing global and didn't get signal. This is since A11 Verizon update. So might just be my carrier. Did however work on A 10 perfectly
[OnePlus 8 Guides, News, & Discussion] sjgoel:
I also tried to convert again to global, I flashed the stock fastboot ROM (11.0.0-GLOBAL-OnePlus8Oxygen_15.O.30_OTA). Flashing went well but phone ended up on the bootloader screen. Tried the earlier A10 global ROM versions but with same results. So am forced back on T-Mobile.

Do not know why when the same procedure & same global ROM had worked perfectly few weeks ago?
[OnePlus 8 Guides, News, & Discussion] mattie_49:
Are you making sure to go into recovery after flashing global and doing a full wipe? Factory reset . Will not boot to anything but bootloader if not.
[OnePlus 8 Guides, News, & Discussion] sjgoel:
No, I did not do that.

Just to confirm, after flashing recovery, I need to go to the device recovery (which shows up in English & 2 other languages) & do a full wipe, then reset?
[OnePlus 8 Guides, News, & Discussion] mattie_49:
That's definitely your problem. Flash global rom,get to recovery one way or the other after it's finished and yes it's the screen your speaking of. English,advanced. Wipe data,factory reset. Have to wipe data when switching from one build to the next. Stinks to set-up again but that's unfortunately what has to happen..
[OnePlus 8 Guides, News, & Discussion] sjgoel:
Great, and thanks.

I am on T-Mobile Android 11. Which global version should I flash? 11.0.2.2. seems to be the latest, or does not matter as it will upgrade OTA automatically.
[OnePlus 8 Guides, News, & Discussion] mattie_49:
Get the latest a11 version you can. And local upgrading will probably break data. So after you flash . Just stay where your at. You can try taking ota after flashing,if it breaks data. You just have to start over.
[OnePlus 8 Guides, News, & Discussion] sjgoel:
Thanks a ton. Will try & report.
[OnePlus 8 Guides, News, & Discussion] mattie_49:
It will indeed work
[OnePlus 8 Guides, News, & Discussion] sjgoel:
Worked finally. thanks.
[OnePlus 8 Guides, News, & Discussion] 2matos:
when im at the recovery screen i dont have advanced. Wipe data,factory reset. my advanced only shows reboot to fastboot and recovery again
[OnePlus 8 Guides, News, & Discussion] mattie_49:
Thought that was your issue. Good deal
[OnePlus 8 Guides, News, & Discussion] sjgoel:
I tried flashing latest 11, but that did not work. So I had to MSM to 10, and then upgrade to 11. Thanks for help.
