1. No unlocking the bootloader will always perform a factory reset.

2. This guide isn't for that. It serves as a repository for T-Mobile variant patched boot, or explains how to get your own images to flash via fastboot to be able to root past Android 10. Since Twrp doesn't support Android 11 yet.

As for the perks of switching to global a few I can think of would be.

No T-mo bloat.

Updates from Oneplus containing all features.

I believe it enables the local upgrade option for downloading, and installing updates downloaded via The OP website. (Only global/non tmo updates are available on the site).

I'm sure there are probably a few other minor differences.

As far as I'm aware the process isn't as straight forward as it used to be with the 6t, 7 etc. So there is more of a potential for something to go wrong. Could be off putting for some I suppose. For more details I suggest looking at one of the conversion guides. :)
[OnePlus 8 Guides, News, & Discussion] rophiroth:
Why a factory reset should be needed in that part... :/

thank you
[OnePlus 8 Guides, News, & Discussion] TheLogicalGamer:
I'm not entirely sure as to why. It just part of the process (on every device with an unlockable bootloader).

Aside from potentially saving on troubleshooting down the line. Perhaps it's a liability issue. Since technically unlocking the bootloader does make your device less secure. The manufacturer can't be to blame for stolen/lost data since anything you would've put on the device would have been put there yourself. The warning message doesn't appear until after the bootloader is unlocked. So by wiping the device before hand/during the process it insures that you have seen the warning, and are choosing to put said data on the device of your own free will after having been warned.

So my best guess would be to protect themselves from potential lawsuits. Assuming that there is no technical reason for needing it. (Which I'm not entirely sure that there isn't).

When I try to flash anything else, it says:

I had to run an adittional command:
[OnePlus 8 Guides, News, & Discussion] TheLogicalGamer:
Try running

fastboot getvar unlocked

And let me know what it says.

Also did you let the phone boot up all the way before attempting to flash the boot image?

Edit: Did you run the fastboot oem unlock command after flashing the unlock code?
[OnePlus 8 Guides, News, & Discussion] TheLogicalGamer:
Yeah just looked at the guide, and it seems I forgot to include that step. Everything is fine. Your device is unlocked just not the bootloader. Before you can flash the boot image you'll need to run this:

fastboot oem unlock

Then confirm using the volume keys on your phone. Then you'll be able to flash the boot image. I've added that step to the guide. Sorry for the mistake.
[OnePlus 8 Guides, News, & Discussion] rophiroth:
Yes, I unlock my phone, run magisk... and safety check mark everything wrong z,z Happen to anyonemore?

I'm sorry, I didn't see there wasn't enabled by default. That's works well.

Pd: some one experience heat after root? Maybe it's just te restoration of files and all..

Thank you
[OnePlus 8 Guides, News, & Discussion] TheLogicalGamer:
Sorry was doing some repairs on a phone. I haven't noticed any different. It could a get a bit hot during first boot from what I remember. Just keep an eye on it, see if it cools down. But rooting itself shouldn't cause that no.
[OnePlus 8 Guides, News, & Discussion] ink718:
If anyone needs to SIM UNLOCK & OEM UNLOCK the bootoader: goto Settings> WiFi&Network> SIM&Network> Network Unlock. If anyone can help on how to get the token unlock code, it would help some. For PUK and other unlocks https://www.t-mobile.com/support/devices/android/oneplus-8 and then scroll down to Security. There you have option to unlock several things.
[OnePlus 8 Guides, News, & Discussion] ink718:
How can you find out if your SIM Unlocked?
[OnePlus 8 Guides, News, & Discussion] TheLogicalGamer:
You can only unlock the bootloader if you have the sim unlocked. Which usually happens when you paid off your device, but if you've been on the network for 40 days, and made a couple of payments you can usually get them to do it for you. Might have to annoy them a bit. As for the unlock token you have to submit an unlock request to oneplus, and they'll email it to you. However this must be done AFTER getting the sim unlocked. The sim & Bl unlocks are tied together. Can't do one without the other unless a work around is found.

Follow the directions there. Off the top of my head, what worked for me was MSM to 10.5.7, unlock bootloader/root, flash fastboot rom for global OOS 10.5.7, update to OOS 11 through system update two times (gets you to OOS 11.0.4.4), then re-root.
[OnePlus 8 Guides, News, & Discussion] rophiroth:
How about stability? Im getting a lot of random force close on some apps x'D I think I mess something with luckypatcher or whatever,,, clear dalvick cache not helping so im thinking on going Global.. But I've read many people talking about inestability and slower data conection in the past.

Thank you
[OnePlus 8 Guides, News, & Discussion] trinidude4:
It's very stable for me. I didn't have any connection issues with the global modem. I don't think I was connecting to standalone 5g though so I flashed the tmobile modem from 11.0.1.2 and connection is still good.
[OnePlus 8 Guides, News, & Discussion] rophiroth:
What is MSM to 10.5.7, why do you root and then flash the global rom? I cannot update through system update after root :eek: why could you and on global? :O!

Nice work. Testing this out with the latest update today.

EDIT: Works perfectly with patched 11.0.1.3 boot.img. 2 minutes from download to reboot with root.
[OnePlus 8 Guides, News, & Discussion] TheLogicalGamer:
Sorry I've been away for so long. Working with other devices, and dealing with some personal stuff as of late.

Moving back over to this device today, and noticed that installing via recovery has been essientially depricated at this point. I just installed on android 10 to update my device and can confirm it still works. For how long I'm not entirely sure. As far as I'm aware Tmobile and oneplus don't provide downloads for Tmo branded phones. So I'm a lil worried about what this means for the future of rooting Tmo branded OP devices. I'm pretty sure you even need root access to pull the update zip from a device that's downloaded it before installing. (I believe it's in /cache if memory serves). The OP8 should be fine, but this could spell it getting harder to root for future devices without going to global. (Unless of course the bootloaders between global and tmo branded devices are interchangeable.) If anyone has knowledge of that and can confirm I'd greatly appreciate it. I'll be uploading the latest patached boot images at some point later today. Again sorry for leaving you guys in the dark. Honestly didn't think this would get that much traction. lol

Edit: I'm currently in the process of trying to convert to global. Not sure how I'm gonna get a anroid 11 tmo modem if I need it. I'll figure that out later. However I don't the believe the method I post will still work. Even with auto update turned off in developer options. After msming back to stock and downloading the update it rebooted automatically without prompting me to reboot. Tried it two or three times in case I was doing something wrong. If anyone happens to have any sucess I'd appreciate them letting me know the details.

Hey could you make a patched image for 11.0.1.3.IN55CB. I'll appreciate it.

If I use patched images from Global/Europe and also use a different OsygenOS version than my installed version which is 11.0.1.3, Does flashing different version will result in a boot loop or things like WiFi/mobile network not working ?

If I only flash the version that matched with the installed version (Meaning I have T-Mobile), will T-Mobile tab still be visible when swiping left to open google feeds. Or will it it go away. Will I'll be able to install international updates via OxygenUpdater App from PlayStore.
[OnePlus 8 Guides, News, & Discussion] DZxda19:
After you rooted your T-Mobile Oneplus 8, are you able to get rid of T-Mobile tab in google feeds when swiping left ?

And are you able to get local updates working ?
[OnePlus 8 Guides, News, & Discussion] trinidude4:
You can get the t-mobile full OTAs from here:

This is the only place I've been able to find them so I can extract the payload.bin.

The latest version is for 11.0.3.5: T-Mobile 11.0.3.5.IN55CB
[OnePlus 8 Guides, News, & Discussion] DZxda19:
Hey were you able to get rid of T-Mobile logo at the boot up screen ?

I have just this question If I flash T-Mobile OxygenOS version like 11.0.1.3.IN55CB will I get global updates directly from Oneplus and TM logo disappears ?

Second, If I flash some global update from Oneplus official firmware site, will it create issues like WIFI, bootloop on my T-Mobile variant ?
[OnePlus 8 Guides, News, & Discussion] trinidude4:
If you stay with the T-Mobile firmware, I'm not sure if you can get rid of the TM boot up. If you have root, there probably is a way, but I haven't looked into it. You won't get global updates directly from OnePlus.

I switched over to global and I don't have any issues with wifi or bootloops. The TM boot screen is gone. The only reason I still look at the T-Mobile firmware is to check if the T-Mobile modem works with the global firmware. For me, the 11.0.3.5 T-Mobile modem doesn't work with global OOS 11.0.7.7. It's not necessary to use the T-Mobile modem with global, but l like to test it out anyway.
[OnePlus 8 Guides, News, & Discussion] DZxda19:
So, you are saying even If I flash a OOS who's version doesn't match with the installed one on my TM Variant, I won't get any problem ?

Because All I am reading is that for to root you should download the patched image or create your own that matches with the installed OOS version on your mobile.

I have 11.0.1.3.IN55CB and i want to flash Global OS from this link. Can i do that even if versions differ from the installed one

[OnePlus 8 Guides, News, & Discussion] trinidude4:
At least for me, using those fastboot ROMs wasn't that straightforward. My issue occurred when I tried flashing directly to a global Android 11 ROM. The modem didn't work at all. I had to downgrade to Android 10 with MSM, then flash an Android 10 fastboot ROM, then install the OTAs up to the current Android 11 version. Everything worked after doing all that.

What you stated about root is correct. The patched boot image needs to match the version you have installed.
[OnePlus 8 Guides, News, & Discussion] DZxda19:
Actually I am confused. I want to root the right way in one go. What you suggest I should do to remove TM logo and get "LOCAL UPDATE" option.

As you know I have 11.0.1.3.IN55CB OOS installed.

FYI, I also have a copy of the PATCHED boot image software build 11.0.1.3.IN55CB which I got from this thread.

FYI, I also have OxygenOS 11.0.5.5.IN21AA (AA = Global) which i found from this site https://www.thecustomdroid.com/oneplus-8-pro-stock-boot-image-collection/

What should I flash ?
[OnePlus 8 Guides, News, & Discussion] trinidude4:
I don't think you get local update by staying with T-Mobile firmware. To remove the boot screen and get local update, you would have to flash global. The problem I had was I couldn't go from T-Mobile with Android 11 directly to global with Android 11. I had to downgrade to Android 10 first.
[OnePlus 8 Guides, News, & Discussion] DZxda19:
So, for me to do this in 1 go.

Flash Global android 10 in my TM android 11.

After flashing, get android 11 update from Oneplus Oxygen Updator and flash this again.

Right ? Will flashing global Android 10 from TM Android 11 cause problems or not ?
[OnePlus 8 Guides, News, & Discussion] trinidude4:
I don't have the experience directly flashing Android 10 over Android 11, but I'm almost sure it will brick you. I didn't want to try that so I used the tmobile MSM tool to go back to 10 first. Then you can start flashing fastboot roms after that.

If I do MSM my Oneplus 8 TM, will it change my imei number too ?

I have a phone whose IMEI number is changed. I actually heard a guy and he said that MSM'ing your phone means "Oneplus MSM tool really allow you unbrick your phone at Qualcomm or CPU Chip level".

I have my imei number changed on my Oneplus 8 T-Mobile variant when I bought. Now if I use MSM tool will it also change or reset the imei number ?

I bricked my OnePlus 8 5G T-Mo and I can't get the MSM Download Tool to see my phone even though I already installed the Qualcomm HS-USB QDLoader 9008 drivers and I'm in EDL mode.
