With certain firmware you can't downgrade. Can run custom P with Q bootloader.

If the version of Q you are on has the same bootloader as the last Pie you can Odin back to Pie

Any P custom rom. I'm on Ambasadii. There is also Ultimate.

Which variant are you using? N960F or N9600?
I know on the N9600, you can Odin atleast 3 versions back before the bootloader blocks it from going lower.

Sounds like you rooted and have a custom Kerbal installed. Did you install twrp as well?

You need P kernel for P rom.
Q kernel for Q rom.
Q bootloader for Q rom.
Q bootloader is bootable for P rom, so it doesn't matter if you can't downgrade. You mentioned that the phone has twrp, so just flash a P rom if you don't want Q(but of course custom rom only, not official).
I upgraded my phone's booloader to android 10(baseband XXU4DSLA) before I flash SuperStable rom(android 10) but a bit buggy so restore back nandroid backup of Ambasadii(android 9). So my phone is now with andorid 10 bootloader but Pie rom

Thread Cleaned.
To one and all. Please be respectful to each other when asking, and replying to questions. As a wise man once said:

Thank you for your cooperation in this matter.

I'm not able to downgrade I went ahead and did the dev bass 7.2 took it all the bootloader and all and I'm not able to revert back to the pi bootloader so what am I to do?. I absolutely despise and hate Android 10 with every fiber of my being

Are you able to provide me with a copy of your nandroid backup? I'm willing to try anything to get back on the pie bootloader and a pie ROM. I'm almost to the point now where I am wanting to sell this phone even though I do not want to sell it.

?You can flash a custom Pie rom eventhough your phone has android 10 bootloader. Just download a rom and flash it through twrp.
Just ignore the booloader.

You need to wait for the December update or downgrade to Oreo to unlock the phone.
Then you will need to use the installation instructions in the first page of this thread.

Guide wanted for Rooting stock Oreo and flashing custom ROMS

Hey, fellow members. I'm a complete noob. Well, not exactly. I have rooted a few of my older phones and flashed custom ROMs but I have no idea how to root my current phone. I've been trying to find a perfect solution ranging from Youtube videos to our own forum threads but I guess I am not really good at searching. I'd be really grateful if someone could give me a step by step guide to rooting my phone and IDK, maybe unlocking the bootloader (if that's required) and then flashing a new Pie ROM. I'm using XT1084 Stock Oreo 8.1 with the latest security patch. Your help will be much appreciated. Thank you!
Unlock bootloader first
For rooting, installing custom roms. You need to unlock bootloader first via fastboot using ur PC. Search the thread for bootloader unlocking process. And then download and install TWRP. Join telegram group http://t.me/g5splus for custom roms and all stuffs
This might help you.
Bootloader unlocking and Root

Thank you so much for providing help. I'll try these out and revert back on my success.

Thank you for providing the links. They were really helpful!
I do have another question. I'm currently using Pixel Experience 9.0 which is supposedly a TREBLE ROM. I want to switch to Bootleggers 9.0 which isn't TREBLE. Will there be a problem if I flash a Non-TREBLE ROM on a TREBLE Recovery? I'm using TWRP TREBLE. I know I sound a little foolish especially with the rubbish nomenclature but I hope that everyone is able to comprehend my words and possibly even figure out a solution for me.

Nevermind.
Got it.
It doesn't make any difference whether I use TREBLE or Non-TREBLE TRWP for flashing a Non-TREBLE ROM.

Downgrading android 10 to pie

Hello forum.
I am on the latest BTU UK version
Of android 10, but I wish to
return to pie. Do I basically just flash
A pie stock ROM? I Want to
Use the light ROM or galaxy project ROM .... So is it straightforward?
Thank you
GARY
Check current bootloader version if it is higher than on old pie firmware than it is a no go otherwise just use Odin
You can flash Pie, version N960FXXS4CSK2

So...SK1 wouldn't work???
Bootloader version is 5th character when you count back from end of build number. It will be S4 or U4..the number is the bootloader you are on.

Did you manage to return back to Pie?
And do you mind me asking why you didnt get on with Android 10 UI2?
I'm on Pie UI1, and I'm concerned about updating and 'breaking' some of the current features that work on my Note9
Thanks

Android 10 takes a bit of getting used to (so does Android 11 DP1 on my Pixel 3XL) -
I downloaded Odin versions of pie SK1 and latest android 10 build, as well as the twrp for the different OS, have gone back and forwards between 10 and different roms on pie, and no problems, as long as you got backup, odin and a stock rom
I tried downgrading to pie Odin reads everything but doesn't flash. It says write failed after a long time. I am using Alienware laptop I'm not sure if there is something I'm supposed to do. Any ideas. Thanks

This is best your note 9 is on a newer bootloader. it is not possible to flash the old bootloader required for android pie
I was able to downgrade my Note 9 from android 10 to Pie pretty easily, but that was with the 1st release of android 10 for the Note 9. I think the newest version of android 10 has a different bootloader. So you would need to unlock the bootloader before you can downgrade to Pie.

that would be because youre on bootloader 4 and thus can downgrade to the latest pie version on bootloader 4

Guide me please

Hey, so first of all sorry for making a long post and I might repeat things for which there may be threads so sorry in advance regarding that, so moving on ,I just bought k20 Pro, while miui is awesome , I'm thinking of switching rom, but can't do it rn as I'll be traveling soon and don't want to risk bricking my phone, I'll do it asap after I return (in 1 week) so my questions are:
1) How to unlock bootloader?
2) How to flash recovery ? And which one , I've always used TWRP on earlier device, but some ppl I see here say Orangefox.
3)I know how to flash a ROM, but what is the vendor everyone keeps telling to flash and should that be flashed everytime installing new rom?
4) Do you lose support for hd in prime and Netflix after flashing rom? If yes how to bring it back (if possible ).
5) ROM recommendation! I've used Lineage os on my previous device, so close it would be good, recommend something which is stable and fast , I don't use much customisation, and should be close to stock Android, as less bugs as possible.
6) Anything I need to know about the device? Something which will help me in future.
Note:i I've upgraded to Miui 12 so please try base answers on that version. I have Indian version of phone.
Thank you to the folks reading this and answering!!

Here's a guide to unlocking the bootloader. This is from the official MIUI global forums.
https://c.mi.com/thread-2262302-1-0.html
Stick with TWRP. Get it from here
https://forum.xda-developers.com/k2...icial-twrp-xiaomi-redmi-t3944363/post79823568 get the latest version. Orange Fox is a good choice of you stick with MIUI or a MIUI based custom ROM. Otherwise TWRP is the better option. Flashing instructions are there. You shouldn't need to flash the vbmeta patcher.
Check out my guide here, read the thread as some of your questions are answered there including a basic overview of vendor and firmware.
https://forum.xda-developers.com/k20-pro/how-to/simple-guide-flipkart-owners-t4151007/post83329343
If you are used to LOS, then you may as well stick with that. It's as stable as any ROM for this phone.
https://forum.xda-developers.com/k20-pro/development/rom-lineageos-17-0-t3976469/post80406191
If you stick with Indian firmware and vendor, you should keep widevine L1.
If you get in a mess, follow this guide from the official MIUI forums to restore the phone with a fastboot ROM.
https://c.mi.com/oc/miuidownload/detail?guide=2
You will need to view this page in desktop mode, if viewing on a mobile.
You can get the latest MIUI fastboot ROM from here.

Question Custom roms for SM-A336B

Hello
Is there any custom rom for the a336b with no bugs? i'd really like to mod my phone bc oneui sucks ass.
Thanks
If you have ONE UI 5.0 , not 5.1 or 4.1, you can install TWRP* and a lineage GSI. Guide, shoutout to Privacydroid.
P.S. The working TWRP is beneath his first post.*
P.S.S. Remember to only use it if you have One UI 5.0, I tried installing it on 5.1 and I got softbricked.
P.S.S.S. No offence, but I dont think youre allowed to swear on the xda forums.
Thank you, is there any way I can downgrade OneUI 5.1 to 5.0?
Yes, so you have to unlock the bootloader, and then you got to this link. Choose the firmware with PDA .
A336BXXS4BWA1
I assume your CSC is EUX, if its not just change it. If you dont have the March patch you dont have to unlock the bootloader but i would do it anyways because you have to do it to install TWRP and Lineage GSI.
Hello.
I have been googling for 2 days now for a custom rom for a33 5g android 13, 5.1.
