Good to see this.
Not sure why this phone doesn't have anyone developing Kernel/ROMs.

Tried... and got stuck here...

But I can get ahead by Installing the .zip file using Recovery Mode.
How to access Recovery mode?​Power off your phone, then press and hold Power button and Volume up button simultaneously to enter Fastboot mode. Then select Recovery mode by pressing Volume down button and enter it by pressing Power button.

I upgraded without clearing the Cache...
After the upgrade .. the first screen after boot to Android 12 will crash.
I booted back into Recovery Mode and cleared Cache and all Data as well (The ROM images .zip will be lost as well). Perhaps I didnt have to clear Data ... someone else can confirm.
Then after boot, I had Android 12 Beta and regular FunTouch setup....

Ended up in a boot loop, which I had to get service center to fix.
OS can be imaged using fastboot... but I guess no one knows the procedure.

First the 10 beta version recovery flashed
https://download.c.realme.com/osupdate/P2Q.ozip
After that, flashed last V9 old version A12 there is no night mode + SOT
https://download.c.realme.com/osupdate/Q2P.zip
If you want a newer normal setup from the file manager version last V9 A21 night mode + SOT working
https://download.c.realme.com/osupdate/RMX1851EX_11_A.21_OTA_0210_all_201912092010.ozip
After flashing the p2q zip can I flash directly the latest coloros ozip available from realme website or is it just the q2p zip which can be flashed
data backup needed?
Thanks a lot for posting this.
So do we need to take backup of the device, while doing the " 10 beta version recovery flashed- using P2Q.ozip"? Like the photos and videos and data will be in the same way or it gets cleared?
And also, if possible, can you post the details steps of it?

Yes , you need to backup your storage
Android 10 will be forced downloaded and installed on ur phone after downgrading to 9
Can't copy the Q2P file to the phone. Instead, I get the message "Cannot copy item. The device has either stopped responding or has been disconnected". Tried several times. I can copy over all but that file, for some reason.
EDIT (17/3/20): Downloading it via the phone, instead of the computer, proved effective.
Stuck on beta version
After installing ptoQ when it's on Android 10 24/03/2020 update it stuck on beta version
Which is not allowing to flash other ozip files
Such as p2Q and the official stock rom RMX1851EX_11_A.21_OTA_0210_all_201912092010.ozip
Unable to disable quotas on dev/block/platform because system/bin/tune2fs is missing
Installation aborted
Little help will be appreciated...
cant Flash
I can't flash the Q2P, the writing failed installation

Tutorial: Registered for One UI 3.0 Beta on SM-N981U1, but didn't receive beta update

I believe this only works if you have already registered for the beta program.
Ok, so, yesterday, my device finally allowed me to register for the One UI 3.0 beta, however, after 24 hours of checking for an update and never recieved it, I tried out of theory and curiosity, <---lol, and successfully forced the beta to show up. First, I can only verify that this process worked on SM-N981U1 Samsung Galaxy Note 20 5G US unlocked version. I don't take responsibility if it does not work on other models, as I am not the wealthiest, so, I'm unable to afford other models to test. Here's my process:
1. download Samsung USB drivers for your device.
2. download adb & fastboot tools.
3. download latest version of odin.
4. BACK UP BEFORE ANYTHING ELSE, IT MADE ME FACTORY RESET, SO, MAKE A BACKUP! *Make sure you know your username and password, because I got the "Unauthorized reset attempt" warning and kinda thought I accidentally FRP locked myself out, because, I'm new to this and I'm not always prepared. lol.*
5. head to the sammobile website.
and download the first firmware version from August, 2020. For mine, my CSC is XAA, Model: SM-N981U1.
6. Extract firmware into a folder you can keep track of.
7. In Odin, flash AP, BL, CP, CSC, and HOME.
8. When Odin finishes, it boots a couple times, then, it will make you factory reset, in order to start.
9. When it boots, it will go through the setup process. I personally skipped everything except samsung account, because, I was testing my theory and knew I might need to reset again in the near future. lol.
10. Once it's set up, download Samsung Members App and verify that device is still enrolled in One UI 3.0 Beta Program.
11. Check for software update.
12. download and install update.
13. Phone reboots, and can be set up.
Tip: Make sure you check software updates to see that you're on the latest.
Update: I've updated my note 20 two more times, since I posted. It's now on the December security patch.
Thank you for the tutorial.
Anyone tried?
I didn't try the above, but I just got the One UI 3 beta today. So far, so good. Bonus: WiFi calling seems to be enabled on my unlocked N20 Ultra:victory:

Weird behaviour in In depth test application

I am in Android 11 C.06 ver. I installed deeptest app for this version. And when I open the app button says Request to exit deep testing like I already applied. When I click the button it shows No network connection. I tried both WiFi and data, no luck so far. And when I click on the Query approval status it says Application not submitted. (See the screenshot for clarification).
So I downgraded to Android 10 A53 version. Then the deeptest app worked fine and my request accepted. But when I click on the Start in depth test the phone reboots to system instead of fastboot. Tried hardware key combination and adb commands. It's just shows the fastboot logo and reboots to system. (The same thing happened with android 11 too)
So again I upgraded to 11 and still the same issue exists in deeptest app like shown in the screenshot. I searched a lot in Google. Never found anything.
Someone please help me. I just want to unlock ky bootloader.
And when I decoded the deeptest apk, I saw a lot of deprecated functions in the app like network connectivity check, etc. But If that was the issue, then why it's working on other RMX3 SZ phones?
Also tried different deeptest apps. No luck.

You should wait for 10 minutes after approval deep test it's works only on a06 version .. don't try on a53 there is risk to brick device for more help watch this channel https://youtube.com/channel/UC3ZscJ8C4y1LN1bmNIMz_pw I am on pixel plus 3.7 July 10 nice full os without bugs

He was able to unlock his bootloader, I'm in the same situation as you, only attacking version A.53 I can't find OTA updates to upload to Android 11, maybe if you could guide me to upload to C.06 I would appreciate it

Question Tonight I start the process of Rooting my Nord 20 5G CPH2459 8 Digit Serial Number

My phone is the CPH2459. I purchased it with the July 5, 2022/2022-07-05 Android Version.
1. I enabled developer mode.
2. I had enabled oem bootloader unlock
3. I had enabled "Disable Updates at startup
4. I has disabled automatic play store updates.
Two days go by and the phone goes behind my back and installs an Android 11 update so now I'm on Android 11 September 9, 2022/2022-09-05 update.
The phone tried to mention that it wanted to start the next update to Android S or some nonsense but I decided to stop right there and factory reset it.
After the reset, I'm still stuck on Android 11 September 9, 2022/2022-09-05 update.
Now tonight I want to try and continue rooting this phone unless there is a way to rollback to original Android 11 July 5, 2022/2022-07-05 Android Version.
What would be my next steps. I have downloaded everything I've been suggested to a usb so I can keep working on this step by step. You guys are awesome for sharing this information. Thank you for what you do.
Absolutely! And thank you. Heading home now so Ill shoot you my info.
Once I get familiar with getting this to run on one os I should be able to save copies and then jump back and forth right? I always wonder if it will be like how samsung and other manufacturers sabotage attempts to downgrade and other such annoyances.
So I would go here?

Then I would download which one of these stock boot images?
Followed by which Firmware version?
Just want to make sure I'm on track. None of them say US version, so I'm assuming Global version?
I'd like to know if he ever backed up his rom...I could use a copy.
I see. May I send you a pm?

There is no known release date for Android 14 yet, but we suspect that it will follow the same release cadence as in previous years. Android 13 dropped in its developer preview form in February 2022, followed by another developer preview, then four more beta releases until the final release of Android 13. With the first Android 14 developer preview arriving on time and followed up quickly by the second, it seems likely that we'll follow a similar release cadence to last year.
