It's already dirty, so it can't be locked back in.
Lock it up and downgrade it with a QFIL.
That's the screen
Unlock and QFIL downgrade
If you re-lock, you'll get a screen
If the same zui13 version is lower than the original version, it won't lock
Only the original version will be locked again.
I just wanted to see how zui13 looked and come down again, but it's a catastrophe.
Personally, I liked zui12 better,
I was forced to stay in zui13.
I hope it's a good post for those of you who are still in zui12.

Oof, thanks for letting us know.

Found this out..a round trip to China was needed

I've re-upgraded to 13.0.430. However, relocking still result in the same device is corrupt message.
How do you go back to the original version (13.0.430, I assume) from zui 12?

Rollback from Nougat (EMUI 5.0) to Marshmallow (EMUI 4.0)

Hey guys,
I have a big problem with my Mate 8. My build number was NXT-L29 C636 B170 and I never got any updates, because I was using this asian build with a european SIM-card. Because of these annoying notification bugs B170 has and because I was about to factory reset my phone I thought about updating it manually.
Tried to understand how all this works and started to do a small OTA update first to test if it's that easy. With the B180 from the screenshot of FF below I easily managed to update my phone.
What I tried next is to go to Android 7.0, so I used the selected blue FullOTA-MF-PV. My phone updated successfully and works really smooth, but now I see "NRD90M test-keys" as build number. I read a lot of bad things about this version because it seems to be a really early and bugged beta version and thats not what I need. I already wanted to try a factory reset but also read that you should completely avoid doing that.
I want to go back before anything unsuspected happens to my phone. My updater has gone, so I cannot install anything else. Can anyone explain for a newbie how to get back to my previous build?
Was it wrong to use the PV version?
What I want to reach then is an updated version of my phone software as a stable version.
Hope anyone can save my phone
Thanks in advance

I have an SM-F700U1/DS (US unlocked) and also don't have it. I found this article, which isn't specific to the Z Flip, but I'm going to try waiting the 7 days and see if the option magically appears. I'm aware this thread has been dead for a few months so I'm curious if anyone got it to show up.
Those instructions do not work. Nothing I do will get OEM unlocking to show up.

Hello did it work after 7 days?
I have Korean Z Flip 5G and the option is there once the developer options is enabled. Maybe it's due to the differences between regions?

There is any way back to the older(older than 16.1220.1909.194) or the first fimware? I think maybe it's the fimware 16.1220.1909.194 newer than the unlock apps...I tried the ADB but cant wrrote the older fimware...
Sry for the image...looks like it can't show out by google cloud drive.

Did you finally solved this problem?
I saw somewhere people saying to remove device pin before you try unlocking bootloader. I guess you can try that.
Anyone found a solution for the bootloader unlock?

I don't know for sure but think there is no actual difference. I've unlocked my bootloader and rooted being on latest 1CUA3 (11 Android) TGY without any issues. Then flashed 10 Android just to check some things and then flashed 11 Android back. Why do you want to use 10 android firmware? Want to stay on that version after root?

Yes currently on Android 10 and want to stay on it.
Will uogrwde once all bugs have been smoothed out.
Kinda like Android 10 stability and battery life
I got it. Then I would take the latest upload just in case. By the way, what's the name of app you use for this? I'm usually downloading to my PC using Frija app for Windows.

Oneplus 7 Pro Widevine in L3 even though my bootloader is LOCKED

Hi Does anyone have a fix for OP7 Pro where the bootloader is in L3 and wants to go back to L1?
I have read on many sources across Reddit and XDA forums about locker the bootloader however my fastboot says my device is locked (i also do not remember doing anything to unlock the bootloader)
Any help would be appreciated. Apologies if this has been posted elsewhere, i have looked but could not locate and i have been trying for months. (https://community.oneplus.com/thread?id=1574423) is my post to oneplus but no one got back to me.

Hi,
didn't know about that, is this a Oneplus limitation ? Or will they unlock it later ?

Apologies, I have flashed before but not as knowledgeable. would flashing to unlock allow access to L1 again or am I flashing to relock the fastboot?
