How to install all custom ROMs - OnePlus 7 Pro Guides, News, & Discussion

Each ROM thread has a different installation guide.
So I was confused and tried various installation methods.
"Step 1/2" and "Step 2/2" shown during installation rom, probably means installation on each partition (A, B).
If so, this is the most COMPLETE way I have tried
[Clean Install]
0. reboot to TWRP
1. Format Data, Wipe Cache
2. reboot to recovery
3. Flash latest OOS (necessary)
4. Wipe Data, Cache
5. Flash ROM, TWRP
6. reboot to recovery
7. Flash gapps, magisk (If you do not want to be encrypted, flash disable force encryption)
8. reboot to system
[Update]
0. reboot to TWRP
1. Flash ROM(+TWRP)
2. reboot to recovery
3. Flash gapps, magisk (If you do not want to be encrypted, flash disable force encryption)
4. reboot to system

[GUIDE] Flashing Guide - Custom Rom to OOS

First off you will completely lose all of your data. I highly recommend backing up all of your internal storage because it will all be gone.
Also I recommend investing in a good quality USB-C OTG drive. It comes in very handy with any TWRP encryption issues. You can always use ADB if needed, but the drive makes it 10x easier.
Things to download
1. OOS Full zip. Do not use an incremental update. - https://forum.xda-developers.com/showpost.php?p=78026655&postcount=2
2. Latest TWRP Installer - https://forum.xda-developers.com/on...overy-unofficial-twrp-touch-recovery-t3861482
3. Magisk - https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
Steps.
1. Reboot to Recovery
2. Perform an Advance Wipe (Dalvik/Art Cache, System, Vendor, & Data)
3. Factory Reset
4. Flash OOS Full Zip on slot A
5. Flash TWRP
6. Reboot to Recovery - You should now be on Slot B
7. Flash OOS Full Zip again on slot B
8. Flash TWRP
9. Reboot to Recovery
10. Flash Magisk
11. Format Data
12. Boot to OOS
Thank you for the details.
What do you mean by step 3 "Factory Reset" ?
Isn't step 2 is a factory reset through TWRP ?
Or......

Wdym? All variants doesn't matter lmao
I'm on A705MN running latest TWRP and your instructions are not very clear. Here is what I am doing and get a bootloop
I advanced wipe cache, dalvik, data, system, internal storage
I format data and type "yes".
install add files for zip of rom, then add second zip of DM-verity
Both flash fine; do not reboot, but go to TWRP home and format data again per your instructions, type "yes"
then reboot system...and I get boot loop.
If my order is wrong please clarify.
Any prints?

7. Wipe: Davik/ART Cache, Cache, Data, Internal Storage, and system.
8. Install PixelExperience_ali-10.0-20201122-2316-UNOFFICIAL.zip
Install failed error 255
I did Try other rom like RevengeOS-3.2-Q-OFFICIAL-ali-20200713-0913.zip but also failed
Please advise!
Turn out these 2 : twrp-v3.2.3-ali.img and twrp-v3.2.3-unofficial-ali_20181110.img won't flash custom rom even after I wipe and format data. The only on that work is mali.img from here:
TWRP 64
So, official ali twrp is 32 bit and most custom roms are 64 bit !?
