how to reflash your original ROM back?

Answering my own question and for others who may need to.
Make a nand back up if the following in twrp.
Data
System
Boot ramsisk
I tried to install a treble ROM but I think the twrp version i'm using didn't allow it.
Going to hope that a compatible treble twrp is released or we are screwed for treble ROMs and let's be honest that's our last hope.
OR
Boot to eRecovery and recover from there, you'll lose all data and recovery but you will retain bootloader unlock.

You dont have to flash the rom to both the slots. Just make a clean flash without format data.
First of all, Stay Encrypted :laugh:
Now from custom rom to Oxygen OS make a clean flash so follow the below:
Must Use Bluspark TWRP
1. Wipe Dalvik, System, Data & Cache
2. Flash the Full OxygenOS Rom Full Zip (Links available on my threads Beta or Stable Pie)
3. Flash the TWRP installer Zip
4. Reboot to RECOVERY to make sure TWRP stays and continue to root.
5. Flash Magisk Stable to maintain root (Avoid Beta)
6. Reboot System and Enjoy the latest firmware without any data loss
Make sure you follow above and also make sure:
1. Use Bluspark TWRP
2. Move from Pie To Pie / Pie to Oreo or Oreo to Pie might require a format.
Similarly follow the same if you want to move from Oxygen OS to Custom Rom, check the rom thread if the developer needs you to flash anything extra or firmware files.
Hope the above helps :good:

Update from OOS 5.1.4 to 9.0.7 with unlocked bootloader + magisk... is it safe?

Hello! I have my OP6 with OOS but I unlocked the bootloader, installed Magisk and now I would like to update via OTA to the OOS 9.0.7 but I need to know if there can be some problemsor consequences like brick or I will lose something. The phone already said that after updating I will lose root :crying:
Can somebody tell me how can I update to Pie safely?
If I need to do a nandroid backupora backupof media I can do it without prob with TWRP and storing all my data in the cloud.
Thanks a lot!
Make a full backup
1-Download the full rom 9.0.7
2-boot to twrp
3-flash the rom (dont wipe anything )and dont reboot because you need to flash twrp just after the rom
4-reflash twrp while you are still in recovery (or you can flash twrp just after the rom by adding it in the queue)
5-reboot to recovery (dont boot to system yet)
6-flash magisk
7reboot to system

How to get back to A10 after custom rom

Hi all so I am planning to install a Havoc OS on my phone with TWRP and Magisk
So my question is in the event that the install doesnt work out for me or that I dont like the rom (no rearson why I shouldnt) how do I get back to the original A10 rom?
I have downloaded the OxygenOS 10.0.6 [EU] OnePlus 7 Pro 5G.zip file from here already. Would I be able to go ahead boot into TWRP and flash this ifneeded?
TIA Bart

Hi Bart,
Make sure you keep TWRP recovery after flashing custom Rom.
Then if you want to go back, flash official Rom zip on both slots after formatting data otherwise it won't boot.
Thanks for that.
Only thing I'm not sure is what you mean by flashing to both slots?
If for example you get a boot loop can you still get into TWRP?
I assume this is a yes as this is before it boots into the phones OS?

When returning to stock,
format data
Flash stock zip
Flash TWRP
Reboot into recovery which is TWRP
Follow the same steps again and reboot...
If you end up in boot loop, don't stress. You can always flash TWRP recovery again via fastboot.

Question Going from lineage 20 to pixel extended. What do I do about recovery?

Sorry, I couldn't find the answer. I installed lineage 20 on my one plus 9. I also installed the custom recovery required by lineage. I want to try out the pixel rom but what do I do about the custom lineage recovery? Do i use msm tools to restore it first? or can i install the unofficial twrp i saw on this forum instead or is there a stock recovery I can easily find to change it back? Thanks for any help.

OnePlus 9 does not have a dedicated recovery partition anymore (most modern phones don't have anymore). Instead, recovery now resides inside boot, meaning they share the same kernel. That's the reason every ROM instruction says to flash the provided boot, vendor_boot and dtbo images. Note that these 3 images are the same found in that particular ROM zip. Anyway, the point is that when you flash boot, the recovery is flashed too.
So, in your case, even if you are on LineageOS 20, and you can access LineageOS recovery, you can just go ahead and do a factory reset and flash the Pixel ROM through adb sideload. After that, boot, vendor_boot and dtbo will be automatically flashed/updated to Pixel's. But the recommended way is still to make sure you first flash those given 3 images before going to recovery and proceeding with factory reset and flashing.
