As of my knowledge "fastboot oem lock" will destroy the system image if it was modified.

I think your info is incomplete !

"Starting with 2018 models (and more recent), there was a regional separation of models at the bootloader level. "Chinese" versions of phones can only have a locked bootloader with Chinese firmware on board. "Flip Flops" do not take into account. It is impossible to block the bootloader on the "Chinese" body when the global (Russian) firmware is installed, get a "brick"."

I am sorry but I didn't get what exactly you are saying. Let me give more details. I have Indian variant of the device. Suppose I unlocked the bootloader, installed TWRP and flashed some custom rom. Later if I wanna relock the bootloader, what exactly I am supposed to do.

To do this, flash the miui fastboot rom via XiaoMiFlash and make sure the "clean all and lock" option is selected.
Of course, this means that everything on your phone will be erased - the phone will be restored to its factory settings as on the day of purchase.

1) If your device came with a Chinese firmware out of the box and you cross-flashed an Indian or a global you should not re-lock it.
2) If your device came with an Indian or a global firmware and you cross-flashed a Chinese firmware then you should not re-lock it.
3) If your device came with an Indian firmware and you cross-flashed a global firmware then no problem with.
4) If your device came with a global firmware and you cross-flashed an Indian firmware then no problem with.

I'm assuming before re-locking bootloader, you have to flash stock rom and stock recovery appropriate to your phone model?

Yes, it's mandatory to re-flash the stock ROM which previously was into device, assuming that it's used MiFlash tool both things are done in same operation.

By the way, did you clean the data( by factory reset or in Recovery Mode ) before or after flashing the 10.0.12?

Question T-Mobile 9 pro flashing

Hello all,
So my op6t died a very violent death the other day. I needed a replacement phone immediately so I went to T-Mobile and bought the 9pro outright. Per T-Mobiles guidelines, I have to wait 40 days before they'll SIM unlock the device. Once they do that for me "oem unlock" option should no longer be grayed out and I can unlock bootloader.
My question is, once my BL is unlocked, am I able to flash the global/international version of OOS? Or am I stuck with T-Mobile roms forever?
Thanks,
Pain

You can unlock the Bootloader when you request a token to unlock.
If you paid full price, why not get it directly from OnePlus with no restrictions?

Hey bud, you don't have to wait 40 days, try this, it's reliable, this person already unlocked like 4 different T-Mobile devices for me and there is also a tread on how to convert T-Mobile to EU. Good luck.

That's usually what I do, but I literally destroyed my phone on short notice (caught in the door jam as I closed my car door). I needed a replacement ASAP for work so I just went to T-Mobile.
And I'll definitely check out that thread and send him a PM. Once it's unlocked am I good to flash global OOS releases?

Global is a problem since updates are coming from Google and we can't get a full image.
Better to flash EU in this regard.

Where do we download them from? OP website or oxygen updater app?

I just did this yesterday!
This thread has the instruction you need: https://forum.xda-developers.com/t/...7-to-eu-via-msm-no-unlock-bin-needed.4272837/
So yes, it's possible, but you'd have to keep the bootloader unlocked and flash the T-Mobile modem after every update. Not a big deal.
I actually tried flashing both the EU (firmware ending in BA) and Global full ROM (firmware ending in AA).from OnePlus and didn't notice any difference. But my understanding is that this month is special in that we can download the full update image from OnePlus for the Global/NA variant.
With Magisk Hide, I was able to get Google Pay working and Widevine L1 for Netflix HD.

Can someone help a cautious betty? How do I backup my oneplus 9 pro partitions without root etc? Thanks

Use MSM tool and back them up. Press f8, ctrl-a to select all partitions, use password oneplus.

Great thanks very much.

Can you restore those backups with MSM as well?

You can with unlocked BL, just boot to fastboot and flash the partitions. You could use SMT download mode, but I wouldn't advise since it could wipe your IMEI and EFS partition.

Question Possible to go from 8 Pro + CN to EU version?

A bit sick of the UI but worried that since the 8 Pro + version is not available in Europe there may be issues. Is there anyone who tried this? Is it possible to install stock firmware from another region?

I know this doesn't answer the first part of your question directly but it works the other way. I have installed CN on my EU model. Interesting that there's a few extra settings in the CN such as updating the GPU directly.
I'm on the latest CN firmware V2.26 and the battery is much better but probably due to all the battery saving default settings.

Yes, you can change the payload_properties.txt in the rom of the region you want to flash. Change the text "nx729j_un" or "nx729j_**" for " NUBIA_SUBVERSION to "nx729j". Put the modified rom in the root directory and use local update. You do not have to unlock the bootloader to do this. If this does not work then you have to unlock the bootloader and flash the recovery of the rom in the region you want to change to and use sideload to flash the rom. However the second method might mess up your phone and you might not be able to boot your phone.

In the payload_properties.txt, change the text "nx729j_un" for " NUBIA_SUBVERSION to "nx729j". Put the modified rom in the root directory and use local update. You do not have to unlock the bootloader to do this. If this does not work then you have to unlock the bootloader by go to bootloader and in the command window type
fastboot flashing unlock
Follow the direction to unlock the phone
You need to extract the payload.bin from the CN rom, then use payload dumper or fastboot enhance to extract recovery.img from the payload.bin. Go to bootloader and flash the recovery of the CN rom (fastboot flash recovery recovery.img)
Then reboot to recovery, choose English when you see "Wipe data" type
adb reboot sideload
Once your phone boots into sideload mode (When you see the two error line at the bottom of the screen) type
adb sideload NX729J-update.zip (this is the CN rom you want to flash)
Whether the transfer is successful or not you can wipe the data and reboot the phone. If the transfer is successful you will be in the CN rom, if not you should be back to your own Global rom. The sideload will load the new rom to the other slot so it should not change the current slot.

I'm terms of unlocking the bootloader all I have to do is go into fastboot mode (with OEM unlock, USB debugger selected on the phone of course) and type in the "fastboot flashing unlock" command and whatever next steps I'm supposed to do? Also I have not set fingerprint and or security pin on this phone yet and I've read that people are having issues with them after unlocking bootloader. Is your bootloader unlocked? If so are you having pin/fingerprint issues and if not was there anything you need to do to avoid the issue when unlocking the bootloader? TY!

Question Help with TMO OP9 Pro (LE2127) A12. What are my options?

I thought I was buying an unlocked global version but goy the t-mobile version. Are there any options for unlocking the boot loader without an unlock.bin?
Additionally, once the bootloader is unlocked (if I wait for the .bin from OnePlus) what additional considerations are there for flashing firmware and rooting the device? I have been trying to sort through the forum with minimal luck.
It lools like MSM will not work without unlock.bin on A12 and later, is that correct?
If i unlock with unlock.bin can I use the OTA firmware from OnePlus site to flash and root, or do I need TMO specific firmware and where would that be located.
Any links to applicable guides would be greatly appreciated.

You are going to be ok. I have the OP9P with stock A13 with unlocked BL, rooted with magisk . Unfortunately I am leaving on vacation and will be limited when I can guide you along but be patient.

I just delt with this last week, and was able to convert to global and OEM unlock without having to use an unlock code from OnePlus or from tmo.
What you need to do is convert your model from LE2127 TO LE2125.
1. Download MSM for tmo OP9Pro, this will be handy if you mess anything up
2. I don't have a link but if you search TMO to EU MSM OnePlus 9 pro you should be able to find the right tool. You just run the MSM like you always would.
3. Now you can OEM unlock your phone by running the command `adb shell pm uninstall -k --user 0 com.qualcomm.qti.uim`
4. Your phone is now no longer TMO but will not work with a US sim card, so you need to convert it to global. You can just download the OTA from OnePlus official website and go to software update in settings and press 3 dots and press local update or something like that.
4. After installing global software, upgrade to newest software version via OTA updates
5. Once complete, reset phone through settings.
6. ???
7. Profit
If you need any help with any particular step let me know

I have the TMO to GLO MSM Tool and will give link tomorrow! I will be on the road for about 10 hours tomorrow, that is why it will take a bit to get the link posted to download the MSM Tool.

Give me a little bit and you will have the link. Don't want to keep you waiting.... Fastboot OEM unlock once converted. Enable developer options, USB debugging and OEM unlock....

Also if you want to get back to stock after unlocking bootloader, let me know....I have the answer for that too!

If you stay with Global, you might need to flash TMO modem if your carrier is TMO.

Here you go... TMO 2 GLO MSM Tool....
3.52 GB file on MEGA
mega.nz

So while I was waiting I got impatient and started playing around with different MSM packages. The problem I now have is that after flashing to either TMO or Global I can no longer toggle OEM unlocking.
The phone was network/sim unlocked before I started and now, even if I get onto an A11 non-TMO ROM I cannot enable the setting.
Edit: After reapplying TMO ROM and going online it has re-enabled. Will try the suggested path now.

Use the link I uploaded to go from TMO 2 GLO, if first try does not work, uncheck the "SHA" and check the "USE LITEFIREHOSE" boxes.

Be sure to read all that I have posted. Patience is the virtue to success...

I will get you where you want to be, but you must be patient!
