Is it stable enough to use as a daily driver
[OnePlus 8 Guides, News, & Discussion] joe1gun:
Been running for three days with no problem.
[OnePlus 8 Guides, News, & Discussion] knightsh:
For me, no problems either. But each user is different. On the OnePlus community thread some people have issues. Depends on your apps and so forth I guess. I'd say just as stable as my Pixel 2xl on the Developer preview which is currently my daily.
[OnePlus 8 Guides, News, & Discussion] joe1gun:
Only problem I have noticed is you cannot access visual voicemail for tmobile. Keeps saying the sim card is not placed correctly. Can anyone confirm?
[OnePlus 8 Guides, News, & Discussion] Temujin503:
Thanks. I'm thinking about updating to the developer preview 3 build.

Is a data wipe required before installation?

Might be a silly question but I just need to know so I can back up all my info and documents in advance plus my 2fa apps and authenticators

---------- Post added at 01:24 AM ---------- Previous post was at 01:15 AM ----------

Anyone have the installation method for installing the developer preview?
[OnePlus 8 Guides, News, & Discussion] knightsh:
The directions are right there on the download page. Download and transfer to the root of your device. I downloaded to my PC and then transferred. Go to your settings, and upgrade. Click the three dots in the corner and go to local upgrade. Find your download and click install. You do not have to wipe data

can i unlock oem with android 11 beta rom? this without the sim unlocked
[OnePlus 8 Guides, News, & Discussion] Scott:
If you skip step 2 you can skip step 5.

No, for the first time ever I am actually getting a message stating that I have to disconnect from wifi to authenticate. Its never done that before. But no, Visual Voicemail is fine for me.

I randomly dont get inbound calls though. A reboot fixes each time. Usually after a 48 hour period.

Text Messages are good to go. Did have an issue with MMS sending pics. Reboot fixes that as well.

Now the bugs I just random glitches. Nothing persistent. Great battery life. But the phone has great battery life anyways.
[OnePlus 8 Guides, News, & Discussion] iKevin:
Actually, I tried without steps #2 and 5 but there were no signal and no FP so I had to redo everything again with steps #2 and 5.
[OnePlus 8 Guides, News, & Discussion] dulcediablo:
Anyone with 11 beta tried to see if dual SIM is working? Supposedly it allows DSDS on 5G now
[OnePlus 8 Guides, News, & Discussion] iKevin:
Does it combine 5G data SIMs for faster throughput?
[OnePlus 8 Guides, News, & Discussion] Scott:
Thats strange. All the other people said they had no issues so I MSM'ed back to stock, no update, flashed and all was well. :confused:

Although, I can say calls and text are being missed. I am going to go back to stock T-Mobile... And still miss calls and text. But not as frequently.
[OnePlus 8 Guides, News, & Discussion] vandizzam:
You are right. I am not rooted and I have had my wife call my phone and have it go straight to voicemail. T-Mobile latest update

---------- Post added at 03:42 AM ---------- Previous post was at 03:41 AM ----------

Also, if you root on T-Mobile latest update, can you please post your patched kernel? It's ok if you can't
[OnePlus 8 Guides, News, & Discussion] Scott:
Yah, I am playing around now. I created a fastboot flashable T-Mobile ROM from the MSM tool. ... Well that didnt work.

I am testing it now. If its legit I will upload it for everyone. It wont be patched though. You could easily patch it using Magisk Manager.

EDIT: I dont know what to do at this point. I am thinking Note 20 but I hate not having root. Int version has issues with calls and text as well as T-Mobile version. WTF?!?!
[OnePlus 8 Guides, News, & Discussion] teegraves58:
Fellas I have already circumvented this issue. Disable wifi calling and all is well. Not a permanent fix, but good enough until we find a better solution.
[OnePlus 8 Guides, News, & Discussion] Scott:
Yeah thats great if you get a signal at your home. I dont. Its not uncommon to loose signal with all three major carriers on any device.

This is the first device that I could not use WiFi calling. The device is solid, the software is crap.
[OnePlus 8 Guides, News, & Discussion] teegraves58:
Oddly enough I didn't start having issues until I switched to global. On rooted tmobile I was about to use wifi calling.
[OnePlus 8 Guides, News, & Discussion] Scott:
Same here. However I had a wierd problem when paired to my Galaxy Watch Active2 that caused the phone dialer to disappear and could not answer except on watch or other Digit Lines. I cant win except to go back to Samsung. This is horrible.

About to try the new 10.x.12 update and see if that is any better however I doubt it.
[OnePlus 8 Guides, News, & Discussion] iKevin:
I don't have any issues with missed calls and text.
[OnePlus 8 Guides, News, & Discussion] xander24777:
Does anyone see a difference in data speeds/service after switching from T-Mobile to global?
[OnePlus 8 Guides, News, & Discussion] Scott:
I wish I could say the same. My iPad and watch just rung 5 minutes ago when my brother called. Phone, not so much. Oh and all the three devices were within 1 foot of each other.

No difference to me. Sucked before and after.
[OnePlus 8 Guides, News, & Discussion] PlzRoot:
got two questions:

1: What is the point of doing this besides the local update option?

2: How how do you update without losing root?
[OnePlus 8 Guides, News, & Discussion] -PaRRoT-:
Hi all, this guide is about converting "T-Mobile" to "Global" or it works also to convert "China" to "Global"?

THank you.
[OnePlus 8 Guides, News, & Discussion] vandizzam:
So you're having trouble on stock T-Mobile and converting to international?
[OnePlus 8 Guides, News, & Discussion] Scott:
I think it should. Make sure you have a stock ROM you can go back to using MSM tool if all else fails.

Yes, Big time. Converted to int, it updated to the latest x.x.12. Same problems.

Wifes S20 has no issues, never had any issues with my S20. Just this device.
[OnePlus 8 Guides, News, & Discussion] -PaRRoT-:
I had the doubt because the difference is only in the available bands for 4G and 5G.
[OnePlus 8 Guides, News, & Discussion] FizzyAps:
i flashed and had full data riight away?

Why that doesn't require backing up persist or modem

Currently ob1

Do issue with signel drops

Or any other issues
[OnePlus 8 Guides, News, & Discussion] ImDonly1:
Is it possible to convert T-mobile model to Global and then re-lock the bootloader (no root, stock) to accept global OTAs and pass safety net without Magisk?
[OnePlus 8 Guides, News, & Discussion] LLStarks:
Is the conversion process missing a reserve.img restoration? Don't we need that for incremental OTAs to work properly?
[OnePlus 8 Guides, News, & Discussion] ThatVolantFox:
Okay, so I just finished reading through this entire thread and like numerous others, I'm left confused because of everyone trying to explain how they did it and giving answers that conflict with each other. I'm currently on T-Mobile 10.5.20 and I would like to move over to global and lock my bootloader so that I can still use things like Google Pay and whatnot, and update to the Android 11 open beta. From what I gather, the path with the most success is using the MSM tool to downgrade to 10.5.7, update back to the latest version (I'm assuming via the settings app on the phone, please correct me if I'm wrong here.), unlock the bootloader using the token obtained from OnePlus, and then flash to the latest global version and install any updates, if any (Via the settings app like before, unless I was wrong about where to update from.), and then re-lock the bootloader? Can I just flash straight to the Android 11 beta after unlocking the bootloader? Or do I need to update to the latest stable global version and then run the local update from the settings app? I'm seeing horror stories of people not having service and losing their fingerprint sensor, which can be remedied by backing up your persist and your modem, but at what points during the process listed above do you make and restore said backups? The issue with permanently losing service if you remove the SIM card also has me worried. I also noted some people having an issue where incremental OTA updates would fail and the full update would be downloaded instead. Has anyone figured that issue out as well? Thanks in advance!
[OnePlus 8 Guides, News, & Discussion] Scott:
Very simple my friend...

1. MSM Back to T-Mobile 10.5.7

2. Unlock Boootloader

3. Flash Fastboot 10.5.11 International ROM

Anything out of sequence or any added steps may cause you issues. Example, some say to take the first T-MO OTA. Not needed. Some say back up persist.img, not needed. I have done this at least... and not an exaggeration, at least 10 to 12 times since I first tried it. Many people will tell you otherwise in the various posts and threads here as you already know. They will tell you to "do this" falsh that, spin around in a circle, hold your breath, and/or "back that up." Out of the 10+ or so times, I only had an issue when I screwed it up (long story) by not reading instructions and manually rebooting my phone to fastboot once it rebooted halfway through. You will see what I mean when you flash INT. The phone reboots after vbmeta image as it should but I got antsy. Anways...

I cant say it is advisable to go from T-Mo to OOS 11 B1. The only reason I say that is because I have not tried it. However, in theory it "should" work, however I am on OOS 11 B1 and am pretty damned happy with it. Otherwise I would wipe and test it for you. Maybe someone else can chime in. I would agree, even though I found it not necessary to restore persist.img its always a smart idea to back it up in case something goes catastrophic.

Here is where I originally confirmed that this worked without a hitch from other users: https://xdaforums.com/showpost.php?p=83216083&postcount=252, Almost 30 days ago and I still have not had an issue. I will say, I don't take out my SIM card or ever feel the need to so I cant speak to that but others that have gone the route I pointed out and have not complained of it either.
[OnePlus 8 Guides, News, & Discussion] ThatVolantFox:
Thank you for taking the time to write that out. I genuinely appreciate it. I'm still waiting on my unlock token, so I'm taking the time to educate myself thoroughly on the process so that I don't mess anything up. Have you ran into the issues others have mentioned that arise from removing the SIM? Or the issues with incremental OTA updates not working properly?
[OnePlus 8 Guides, News, & Discussion] Scott:
Yeah, I have been editing this post since I first posted it... Sorry about that...

The issue with incremental update is a non starter. Any OP device with unlocked bootloader that I have owned would only pull the full OTA. Trust me, this is a good thing! I used to manipulate OTA files for Samsung S devices when I was a ROM chef, meaning I would take the OTA and adapt it so everyone could use it even if rooted. or had mods, etc I tried to do that with this phone but couldn't get it to work and lack of motivation and a fast WiFi connection contributed to that lack of motivation.

SIM card. Hold on let me pop mine out and reboot it.... BRB.

---------- Post added at 09:38 PM ---------- Previous post was at 09:33 PM ----------

Ok popped SIM card out. Watched cell signal indicator go to the empty one with the x. Put SIM card back in. 5 G came righ tup with no issue.

The only issue I had with it was not a OP issue. Its a Samsung issued. And its not an issue, its by design. When you insert or remove a SIM card the Samsung Gear application told me I had to select the proper plan for my watch. Again, this is not an issue, its by design. If I did change carriers I would be miffed to find out I forgot to port my watch over to the new plan.

I am on OOS11B1, anything else you want me to try? Im bored, cant sleep, :eek:
[OnePlus 8 Guides, News, & Discussion] ThatVolantFox:
I think that satisfies all of my curiousities for now, unless other bugs are discovered. I just wanted to make sure I understood how to do this the right way and lose no functionalities during the process.
[OnePlus 8 Guides, News, & Discussion] Scott:
Good luck!

Can you relock the bootloader after converting?
[OnePlus 8 Guides, News, & Discussion] Mew789:
Hello,

I have a in2010 version imported from China. How can I transform it to an EU version ?

Thanks,

Richard
[OnePlus 8 Guides, News, & Discussion] Oneplus8:
Hey, I'm not who you were talking to but recently did the conversion. Follow what he said and you will be on international. If you want to lock the bootloader TAKE THE OTA UPDATE FIRST.

1. MSM Back to T-Mobile 10.5.7

2. Unlock Boootloader

3. Flash Fastboot 10.5.11 International ROM

4. Once conversion is done do the OTA update that will be avail.

5. ONLY AFTER taking the OTA re-lock the bootloader (fastboot oem lock)

It worked for me and I have had no issue in my first week. No service loss, no update issues, nothing, I am even on the Android 11 open beta now and everything works as it should.
[OnePlus 8 Guides, News, & Discussion] PhoenixPath:
No issues with signal or fingerprint? I've read relocking kills fingerprint unlock, and that's really the only thing holding me back at this point...
[OnePlus 8 Guides, News, & Discussion] Oneplus8:
Not for me. I use it daily. Can't vouch for others though.
[OnePlus 8 Guides, News, & Discussion] Temujin503:
Does anyone know of a workaround or a fix for losing signal completely after removing the Sim card after doing the conversion.

I've had to take my son out twice and both time I was unable to get signal on my device at all.

Both times I had to start the process all over again.

Does anyone know why it does that after removing tour sim after converting to global.

I guess the real question is there anyway to fix this as I often have to switch sims between my OP8 and my Pixel
[OnePlus 8 Guides, News, & Discussion] PhoenixPath:
I was going to try this and then...

I enter EDL mode (either through adb reboot edl, or power off > volup+voldown > plug in cable) ... and then reboots the device. I cannot keep the device in EDL mode; it always reboots the device.

Has anyone else experienced this? Am I doing something incredibly wrong/obvious to everyone but me?
[OnePlus 8 Guides, News, & Discussion] ThatVolantFox:
I can't seem to get the MSM tool to work to begin this process.

When I click the start button it tells me that the SMT config cannot be found and force closes itself.
[OnePlus 8 Guides, News, & Discussion] mslezak:
Go to the search bar and type time. Click "Change the date and time" that pops up. Turn off "set time automatically" and turn off "Set time zone automatically". Click "Set the date and time manually"; Set the date back to 2019. Disconnect from WiFi. Then run the unbrick tool. I was having the same issue and SomeRandomUserName pointed me to the fix.
[OnePlus 8 Guides, News, & Discussion] ThatVolantFox:
Sweet. I'll give it a go. Should I root and back up my persist if I intend to re-lock the bootloader, or will I be fine if I follow the steps that Oneplus8 mentioned in post #331?
[OnePlus 8 Guides, News, & Discussion] PhoenixPath:
Between 1 and 2, did you set up the device? (Google account, fingerprints, face-unlock, etc); or was it just enough to get in and enable OEM unlocking?
[OnePlus 8 Guides, News, & Discussion] Oneplus8:
I went through the screens quickly to get to usb debugging. Didn't input anything I didn't have to.
[OnePlus 8 Guides, News, & Discussion] Scott:
No, that would be a waste of time. Skip through every step of the setup.
[OnePlus 8 Guides, News, & Discussion] mslezak:
You may as well backup persist since it's easy to do. dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
[OnePlus 8 Guides, News, & Discussion] 2matos:
what do you do to restore the persist after backing it up?
[OnePlus 8 Guides, News, & Discussion] mslezak:
Restore persist.img

fastboot flash persist persist.img

Only if you lose FP...

Went from sprint oneplus 8 which is just tmobile to running Android 11 beautifully but I lost 5g I just show 4g and 1x is there a way to get 5g back and wifi calling txting
[OnePlus 8 Guides, News, & Discussion] squirrell84:
Ok I miss 5g
[OnePlus 8 Guides, News, & Discussion] Scott:
Just flashed the latest T-Mo 10.5.20 MSM ROM. I then fastboot flashed to International 10.5.12. Then local upgrade to OOS 11 Beta 2.

No issues :p

Yea it's also weird on beta 2 the update today I restarted my phone and now half don't work

What do you mean half dont work?

Im on Beta 2 and doing really well.

Can I do this with locked tmobile version of phone?
[OnePlus 8 Guides, News, & Discussion] RandomPooka:
I'm thinking the same thing, and wondering if there's any way to bypass the sim unlock requirement for unlocking the bootloader, like there was for the oneplus 7 pro using a specific open beta release as a stepping stone
[OnePlus 8 Guides, News, & Discussion] jtimm2121:
The only thing I have seen about this is people saying they think it can be done. I would love to hear if someone has actually tried it and what happened.
[OnePlus 8 Guides, News, & Discussion] hyelton:
No as you'd need to unlock the bootloader, and to do so you have to be unlocked.
[OnePlus 8 Guides, News, & Discussion] Scott:
No, the phone must be SIM unlocked to bootloader unlock. As of now there is no know exploit for either SIM or Bootloader... That I am aware of anyways.

Best bet, assuming paying off in full is not an option, is to talk to the guy in the SIM Unlock thread. He can help you unlock SIM then you can unlock bootloader. He unlocked my phone and many more. At first I wasnt sure if it was trust worthy but he is.
[OnePlus 8 Guides, News, & Discussion] RandomPooka:
I'd love to, but he's closed shop for now and isn't accepting PM either. I'm not gonna be THAT person
[OnePlus 8 Guides, News, & Discussion] peakyblinders:
I am facing the same issue. Did you find any workaround? I too often swap the sim cards on my phone. After i change/reinsert the sim on my OP8 it is losing signal which is pretty annoying.
[OnePlus 8 Guides, News, & Discussion] RandomPooka:
Got a sim unlock last night through TMobileHelp on Twitter. Was straightforward and told them I wanted it to unlock the bootloader so I could flash development OS and kernel software. It tooh about 5 minutes for them to look at my account status, and it was granted. Haven't even had the phone long enough to make my first payment on the purchase plan.
[OnePlus 8 Guides, News, & Discussion] ecompton59:
I lost network on last oneplus 8 so went and did warranty exchange 2 months ago and tried unlock in network settings few weeks ago it didn't work but today I just tried again didn't call or ask anyone and you see it just worked anything I need to pull or make backup of before I make this phone go stupid I was messing with db files 2 months ago is why I lost my net
[OnePlus 8 Guides, News, & Discussion] Powerrangersbeastmorphers:
No need to Sim Unlock to Unlock Bootloader

No. Sim unlock is not required to unlock the bootloader since unlocking the bootloader requires an unlock token from OnePlus after entering the code in fastboot using the website in OnePlus. The unlock code that you enter on your computer is what you send to OnePlus so they know the correct model to process the token. UNLOCK CODE and then UNLOCK TOKEN. Sim unlock is only required so you get service and can use your phone on different networks. Even your damn phone will say "This sim is now unlocked, can now use your phone on any network". Getting the unlock token for the bootloader is the only thing you have to wait 7 days for. I unlocked my bootloader without a unlocked sim card. Sim card unlocking is also good for when installing betas. I had OnePlus 7 Pro T-Mobile model and my sim was locked when I was already bootloader unlocked and installed Android 10 at the time it came out for 7 Pro.
[OnePlus 8 Guides, News, & Discussion] hungmung:
You do need to sim unlock to unlock bootloader. The OEM unlock toggle in developer settings isn't able to be used until the sim is unlocked.
[OnePlus 8 Guides, News, & Discussion] crazynapkinman:
I am not fully released and have been unlocked by TMobile. I talked to a handful of reps and was disappointed numerous times.

Then, today, less than an hour ago, I simply tried the permanent SIM unlock using the settings menu and it worked!

I'm now waiting for the unlock token from OnePlus.

Perseverance pays off. Keep trying to contact and keep working that Network Unlock option and trying.
[OnePlus 8 Guides, News, & Discussion] sx10:
Do you know if standalone 5G is working on T-Mobile with the International rom? This was added to 10.5.17.IN55CB but I'm really curious if it made it into the OB2. You can tell with Cellmapper or Signalcheck if you can connect to just NR and not LTE-NR NSA.
[OnePlus 8 Guides, News, & Discussion] Dameon87:
No, just NR. Have not seen SA work at all on global.
[OnePlus 8 Guides, News, & Discussion] RandomPooka:
Is this something that would be fixed by flashing the T-Mobile modem? Or is it just not happening until such time as global includes it?
[OnePlus 8 Guides, News, & Discussion] sx10:
Does it at least report the Cell ID for NR? In Android 10 it always reports the cell id as 0.
[OnePlus 8 Guides, News, & Discussion] Dameon87:
Yes it shows the cell identity
[OnePlus 8 Guides, News, & Discussion] RandomPooka:
Now that OOS11 Stable is out, I'm looking to convert my T-Mobile device to global. I do have a free questions I'm not quite clear on, though.

1. Does it matter which minor version number I flash from the fastboot thread, or can I use any of the 10.5.xx files?

2. Is there any reason that I can't just edit the flash-all script to not flash the global modem partition and retain my T-mobile modem from the start? And, does the 11 update even require the old modem? I'm concerned that new global OOS11 versions may not play nice with an "outdated" modem.img

3. Can I also remove the wipe command (-w) and retain user data? Will keeping user data be a problem because of what sub-device variant or region it thinks it is vs what ROM I'm replacing it with?

4. Can I not just flash my backed up persist.img in whole? Or, does that contain stuff tagged specifically as the T-Mobile branded device that won't work with global?
[OnePlus 8 Guides, News, & Discussion] RandomPooka:
Asking about minor versioning because T-Mobile is currently at 10.5.20 and global fastboot only has up to 10.5.12
[OnePlus 8 Guides, News, & Discussion] crazynapkinman:
Is there any way you could PM me this process in better detail?

I've been reading threads a lot and am just getting confused.

I have successfully unlocked my bootloader. That's it.

I'm not sure what steps to take next.

Backup persist.img, backup data, then what? What do I flash next? Will I flash via fastboot? I'm a little lost
[OnePlus 8 Guides, News, & Discussion] forgotenxlegacyx:
Okay so pardon my ignorance, or lack of knowledge as its been years since i last rooted or did any modding on android. what is the easiest or recommended way to go about backing up the persist.img and Modem? and help would be greatly appreciated! thank you!
[OnePlus 8 Guides, News, & Discussion] mattplo:
I'm in the same boat as you. So I'm very interested in hearing some of these answers. Hopefully you get a response back.
