please help flashing oxygen os on my Rooted phone without encryption

after trying and testing almost all roms on my device, i can conclude, there is no better rom than oxygen os (for my usage)
every time i install oxygen os, it encrypts my device, there's got to be a way to install it without losing my internal storage device data
pls help me do it :fingers-crossed::fingers-crossed::fingers-crossed::fingers-crossed::fingers-crossed::fingers-crossed:

You can do it by 3 different way:
1. Flash OOS and flash an OOS compatible 3rd party kernel available in XDA (blu_spark for example).
2. Flash OOS and flash patched OOS kernel for that same version available in XDA.
3. Flash through Redwolf TWRP which has inbuilt non-encryption patch.
Thanks

[GUIDE] [F.A.Q.] [chef] [TREBLE] Common Hurdles and Solutions for First Timers!

This thread is meant to address all the common hurdles that are commonly faced by people who are new to treble devices (chef to be specific) and help them to troubleshoot/avoid some small yet critical steps during flashing new ROMs and working with fastboot and recovery in general. It will be continually updated with new stuff as it goes along.
I will be referring to the Motorola One Power and Moto P30 Note as chef only from now on.
The unlocking guide is available in This XDA Thread!
IMPORTANT:
1. Flashing refers to the process of doing a clean flash, with the inclusion of fastboot -w command
2. Latest ADB and Fastboot drivers are required to be installed, else the installation may halt mid-way.
3. Stock ROM refers to the Android One ROM for the Motorola One Power [XT 1942-2]
IMPORTANT: AS OF RIGHT NOW, PEOPLE WHO HAVE INSTALLED STOCK PIE (EITHER VIA UPDATE OR FIRMWARE) WILL NOT BE ABLE TO USE ANY OTHER ROM OTHER THAN THE STOCK PIE ROM. RADIO INTERFACE LAYER IS BROKEN IN OREO SOURCE BUILT ROMS AND THAT CURRENTLY INCLUDES LINEAGE 16 SO PLEASE WAIT FOR PIE SOURCE CODE FROM MOTOROLA FOR THAT TO BE FIXED.
1. I unlocked my chef . How do I flash TWRP in place of the stock recovery?
Solution:Currently you cannot as there is no recovery partition in the device. You have to manually boot TWRP onto the device using fastboot to use it. Follow as directed:
Boot the device into fastboot mode
Use command fastboot boot <path/to/TWRP.img> to boot TWRP temporarily.
2. I am done with TWRP and I want to flash Lineage OS 16 on my chef. I simply flash the .zip archive right?
Solution:No. Before you flash anything,
Take a backup of atleast your EFS and PERSIST partitions using TWRP and off-load it for safekeeping to restore in future if needed. You can also trigger a full backup if you require.
SUPER IMPORTANT: Flash this .zip file to copy the System A/B partitions. If this step is skipped, you will be responsible to brick your own device. THIS STEP IS ONLY REQUIRED ONCE AND ONLY ONCE IN THE LIFETIME OF YOUR DEVICE! YOU WON'T BE NEEDING THIS THE NEXT TIME YOU FLASH ANY ROM. .
After that, flash your dearest custom ROM and get going.
For Lineage OS 16, follow This XDA Thread.​
3. I am done testing LOS 16, I want to flash a GSI. Shall I use a stock Vendor Image for the GSI on my chef?
Solution:No. The stock Vendor image is causing bootloop issue in most GSIs. It is recommended to use Lineage OS Vendor to flash a GSI on chef. So flash LOS and then flash your favourite GSI.
Also, Super Important: for those who haven't used lineage before flahing a GSI, it is required to boot Lineage OS first before flashing a GSI. ​
4. I am done experimenting, I want to go back to the stock image. How do I proceed?
Solution:Follow this XDA thread for it. And don't install OTA updates directly from the device. It will come in the next step.​
5. I want to install OTA updates on the stock ROM. How do I proceed?
Solution:Follow this XDA post for it. The installation process is described here. You have to be clever enough to get the appropriate OTA update. ​

Anyone have flashed GSI ROM? FOr me after flash GSI HavocOS have bootloop :/

DIdn't flash copy system A/B partitions, stuck on bootloop with custom roms.
Watched some youtube videos and didn't read this post before flashing custom ROM. Flashed Custom ROM without flashing A/B partitions. Now I have a phone stuck on bootloop when done anything in TWRP. or I can use my phone with stock ROM installed by fastboot method.
Installing or restoring anything from TWRP results in boot loop.
Restoring the backup I made before flashing, completes the restoration process normally. But when rebooting to system, TWRP prompts me that no OS is installed. If I reboot anyway, its either stuck on bootloop or reboots to recovery and asks me to try again or factory reset, or boots into bootloader mode.
Installing custom ROM begins with Step 1, takes a bit time and starts step 2 and shows completed. Doesn't echos any comments. But when i reboot, same prompt shows saying no OS installed. Reboot anyway and stuck on bootloop or reboots to recovery and aks me to try again or factory reset, or boots into bootloader mode.
Now I installed stock ROM with fastboot method and phone is boots up into system just fine.
Sometimes TWRP can't mount anything.
So am I stuck with stock rom or is there any solutions?
Also, installing stock ROM with fastboot mode showed this error in between scripts
(bootloader) is-logical:xxx_a: not found
and
(bootloader) is-logical:xxx_b: not found
but is able to use the phone just fine with stock ROM.

help me go to custom rom

Quite a few days ago I flashed the developer rom 9.4.25 to test the developer rom and it successfully flashed and I also installed the new twrp for pie devices and installed magisk also. But after that there were some problems like gps not showing exact location, contacts not showing etc. So I decided to flash a custom rom i.e Pixel Experience rom, but when I followed the necessary steps for flashing pixel rom, after installation, when I rebooted system, it automatically booted to fastboot. I tried several times to boot into system or recovery but the result was only fastboot, nothing but fastboot. Then I tried flashing the older versions of stable miui and then tried flashing the pixel rom but the result was same. Lastly, I flashed that same developer rom and now its still running on it but I want to run pixel rom on my device. The main problem is that I dont find any difficulty in flashing miui roms, but when I try to flash the custom roms like pixel experience, lineage or other aosp, treble roms, after installing that system.img file and then after reboot, automatically fastboot shows up and nothing else, cant go to any other screens except fastboot. What can I do?

Lineage OS stuck at TWRP screen

Hello,
I am new to the world of custom ROMs, I have a huawei mediapad T5. I followed the guide and successfully rooted my device. then I installed TWRP from this link:
https://forum.xda-developers.com/showpost.php?do=showpost&p=76362629
I struggled to flash lineageos 16 on my device, after couple of hours, I found the installation guide from openkirin, that mentioned they don't support TWRP. but as I had already flashed my device with TWRP, I had no backup for stock recovery image. I tried to flash it anyway as mentioned in the openkirin site.
but now it stuck at TWRP screen. I am not sure how can I remove twrp completely from my mediapad t5.
After messing around I managed to boot into eRecovery from huawei, where I got option to download the stock firmware. that saved my day.
But I really want to flash it with LineageOS 16. I am not sure what can be done about twrp. Is there any way to remove it from my Mediapad, or is there any guide to install Open Kirin's LineageOS image onto my device along with TWRP?
Please let me know.
#Update
I managed to install Lineage OS onto my Mediapad T5. But I am afraid, I didn't like it much. It is not optimized for the tablet. There're unnecessary apps like Phone App, Messaging App etc. I only got Wifi version. Plus it has issues with Audio Output.
I am reverting back to stock ROM for now, Until better ROM is available from OpenKirin.

twrp

TWRP
I can't seem to get TWRP to install on my pixel 5 I boot it then use the installer and it just loops to fastboot mode and I'm in an awwl of why,I've done this many times on my pixel 1 and 2.,also I have bugs with it in the Lineage 19.1 official builds and I can never get TWRP to get pass the splash screen with lineage as lineage has it's own recovery.

idk ive been having real issues with twrp since i put droid 13 on my pixel 5 keep in mind ive thrown almost every custom rom on here once with twrp as my recovery bro idk think it may have to do it droid 13

TWRP isn't offically out for Android 12 or Android 13 for Pixel 5.
However Android 12.1 support is coming soon with A13 WIP,
see here

Aside from custom ROMs, TWRP isn't really necessary on Pixel devices due to the ability to flash partitions directly.
It's also worth noting that the recovery kernel lives in the boot image, which also contains the system kernel, so any time /boot is flashed, TWRP would be wiped out.
