How can i downgrade from 12 to 11/10? - OPPO Reno4 Z 5G Questions & Answers

hi there, can someone help me to downgrade from Android 12 to 11/10.
I already downloaded all the things such as stock rom ecc. but when I try to follow the procedure to start the flash "press vol + and vol - and then connect the cable", it seems working but then it shows the Oppo logo.
am I doing something wrong?
I followed some different guide and all of them says to do that procedure..
Thanks.

Yes, i tried. It doesn't work for me because i have a different recovery.

Do you have the TWRP or what kind of recovery.

Download Your official firmware from Huawei's website. Now put UPDATE.APP in sdcard through sdcard reader such as: sdcard/dload/UPDATE.APP
Now press and hold vol+ vol- and power button. Ur phone will install new firmware.

For me, the only that worked:
- once rooted, make sure you get both current status and version (to be checked in download mode) as OFFICIAL (you can use Xposed or similar to do this, different threads can be found on this)
- flash with stock recovery
Hope this can help you as well...

In Xposed I found system status under "Security Hacks" but couldn't find where to change version? Would you please let me know?

You should try to go over specific Mode / Module (not sure about the English translation). To do this:
- Install Xposed Installer (or similar mode xposed mode installer)
- In Xposed Installer, download the mode "Cosmetics Device Status Normal Modification"
- Then, in the mode menu, select ComesticSysScopeNormalizer (or something that looks like this...) to activate
Restart, flash stock recovery, boot in recovery mode... and cross fingers!
Hope this will work
Best,
Sorry if this is too simple, just afraid of the bricking with Knox, etc. Which Stock Recovery do I use with KitKat after rooting?
Thanks!

not a rooted device
My tablet isn't rooted & I don't want to root it because it will violate my warranty so is there any other way to get the screen mirroring to work without rooting my device?

Normally it should work until you flash a custom recovery. But in this case you already set the knox flag. So, it doesn't matter if you are also rooted or not.
For whom it not worked:
After flashing the stock recovery boot once into recovery mode. For some this helps.
Mine's stock unrooted and i get that error too.

Crashing boot looping lines colours bad bad bad tablet

I have a tab s 8.4 sm t705 I was running kk rom I flashed LP rom and now it boot loops. The images I have attached is when it crashes and reboots. For some reason it is showing all lines and either blue or red screen sometimes.
I tried to flash twrp and it will not do it. I am at my wits end what to do any help would be a saviour
Cheers
update i was able to get twrp flashed but now when i try to flash a rom i get cannot mount system?????????????????????????
It looks like you flashed a ROM for the t805 not the t705.
First let's get you back to stock.
Download the firmware for your device from the link below.
Follow the instructions to install it. This will get you up and running again.

No need to flash the bootloader after flashing the stock firmware.
I would do a factory reset in recovery.

Hi ya, I have already done that but issue still there. Now I can boot up and start the setup process and the tablet freezes and reboots about 1 minute into setup process near where you have to sign in to google
Any more suggestions:crying::crying::crying: please
Tbh I think you have a hardware issue.
Now new problem when I try to install twrp it will not do it, If I go into the system recovery and try to do factory reset an error shows as follows
E: unknown volume for path {/sbfs}
E: unknown volume "/sbfs"[/U][/U]
Data wipe complete.
I thought it may be battery related but I have changed to a genuine new battery. still same issue
Please please Tech God help me

After I used it with Lollipop droidboot ww t00j stock .78 I had problems with camera. It works only with kitkat?
@ XHook
have you worked on method to re-lock bootloader..
bricked my bootloader
After flashing this I couldn't access my fastboot. Now I can't even boot to system. I'm stuck at the USB logo, where usually I could reboot to fastboot (via pressing Power & Vol +) to fix this. But now I can't even access fastboot. When I press Power & Volume Up, it shows a battery icon. Please do help @XHook.
Editted:
Sorry for panicking back there. I forgot the reboot to recovery way using Power & Volume down. At least I can still boot to my system. I'll try to find a DIY solution for this. Sorry for panicking, @XHook.
Your tool uses Fastboot of 4.3 version right? Is that the difference?
no more update? camera not found, can this method by xhook solve the problem?
i've tried this version, but make my bootloader missing/bricked, same with ezrawk post
Note : When I installed this version >> 3.24.40.87 latest stock lollipop firmware
@XHook, tell me what your firmware version when you install this UBL method.
Thanks

I was using a custom recovery (TWRP) at that time so I flashed a fastboot via install. If you aren't using a custom recovery, you'd probably want to check this out: Zenfone 5 A500CG, Zenfone 6 A600CG Last chance to debrick (This fix youre IMEI) by swiczak
About the flashable fastboot, try searching for it in the Help & Troubleshooting part, I think the user who upload the flashable fastboot zip was tank0412. Try PM-ing him. Sorry can't help you about this 'cause I forgot where I saved mine.
Goodluck!

[SOLVED] Cannot boot into Cyanogenmod, only TWRP. No ROM's working

Edit: Problem has been solved based on instructions provided here.
Long story short I had problems with the newest Cyanogenmod 14 nightly today and had to Factory Reset my phone. Since then I have spent hours installing different ROM's and have been unable to get any to work. They all install just fine, no errors. However I cannot boot into the OS at all. Every time I try to I am automatically booted into TWRP. I don't understand why this is happening after I have repeatedly wiped my entire phone. There is literally nothing on it, I install from scratch, restart... and am booted right back into recovery mode :crying:
Any help is greatly appreciated. I have a reddit thread going on right now as well regarding my problems earlier today but haven't gotten any help.
TWRP Version 3.0.2
Various ROM's I have tried:
cm-13.0-20160820-SNAPSHOT-ZNH5YAO0J9-Z00T.zip
cm-14.1-20161202-NIGHTLY-Z00T.zip
cm-14.1-20161201-NIGHTLY-Z00T.zip
hmm.. try to reboot into bootloader either from recovery or with help of volume plus power button. then flash ifwi, boot, droidboot, recovery and dnx, then install firmware again. if no luck with that. then you have to flash raw firmware using commands

Thank you for the reply!
Rebooting into either bootloader or with the button commands always brings me into TWRP. Nothing else appears to be possible.
Is there another way I can flash what I need? I am not familiar with flashing firmware and am not sure what ifwi droidboot etc. mean, is there a guide you could point me to for this?
Thanks!

If you were on cm14 then you are on an mm based bootloader. You can only install roms based on that. All of the lp bootloader based roms will do exactly what you described. The other alternative is to downgrade the bootloader to lp.

There is or at least was a bug in CM 14.1 within settings , if did a factory reset within settings ...whether it still there today with latest build ? I've not tested
What it does or did, is render your twrp ineffective , you cannot flash or restore.
Above solution fixed or fixes it fast and you can then restore or install cm14.1
