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

Found my answer in this post: https://forum.xda-developers.com/t/fixed-hard-bricked-le2115.4452435/#post-86967531

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
