Hi, How do I downgrade from stock unrooted 10.3.4 to 10.3.3? Can I simply install the full OTA file via local upgrade? The reason is that I'd like to install Resurrection Rom which is needs 10.3.3 as base. Of course, I'll root the phone once it's on 10.3.3.
Also, the ROM page says I need to install OOS on both slots on TWRP. How do I do this? I'd assume that if the device on stock OOS from the start, that would mean that OOS is on both the slots. Isn't this so? Pls help
Back up your data, download the full version on oxygen updater, delete all in twrp so that 0000, connect to pc to add the 2.3gb OOS, go back to flash. It will flash OOS official both slots and you will go back to stock, you can root and twrp with tool all in one after back on stock. If that for someone reason doesn't work try the fast boot rom in tool all in one, recovery firmware, delete all option. I have done this option before to lock bootloader back

Hi,
So I wanted to unlock my phone's bootloader, but I can't for some reason, I use an unofficial tool called XiaoMiTool V2 and it keeps giving "Failed ADB execution" error, so is it because of the MIUI version? Can my phone roll back its MIUI version back to the OOB version (MIUI 9) if I factory reset it?

Hello,
Just got a Oneplus 9 today. Installed Jaguar to try it out. Wanted to go back to stock to compare a few things.
I grabbed the "stock" files and tried to flash using this guide: https://forum.xda-developers.com/t/fastboot-rom-pc-required-op9-stock-oos-11-2-2-2aa.4275727/
This bricked the phone.
I was able to restore the phone via MSM using the Indian one (lemonadep_22_I.07_210412), but in OxygenOS it states the Phone is a 9 Pro.
I tried flashing the STOCK file again just to see (since I now know I can recover in EDL), but it bricked the phone again.
This allowed me to confirm that for Global LE2115, the European MSM (lemonadep_22_E.05_210324) also works to restore the device!
Unfortunately again, it says the Phone is a 9 Pro.
How would I proceed if I wanted to return a LE2115 to stock and relock the bootloader?
Thanks

Copy pasta:
To get back to global firmware, flash this in the local upgrade tool.
https://oxygenos.oneplus.net/OnePlu...all_2107082125_downgrade_059624cc7298428b.zip
It is the global downgrade package. It will wipe your phone and when it comes back, you will be back on global software.
After you flash that, go to OTA upgrade and it will say it's going to download C.48 but it will actually install 11.2.10.10 and then you will have the latest OOS11.

Can confirm this works!
I used the unnbrick tool from one community server and restored my one plus 9 5g 2115.to stock and locked the bootoader. But I could not get to install any rom because it always took me to crash dump. Hope it helps to get back to proper version for you
