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.

I just flashed the official Android Pie OOS from 5.1.11 through original local upgrade method and when I tried to boot twrp on this new rom, it takes me to CrashDump mode instead. Where did I do wrong?

wrong twrp used. https://forum.xda-developers.com/devdb/project/?id=27466#downloads twrp-3.2.3-x_blu_spark_v9.85v2_op6.img twrp-3.2.3-x_blu_spark_v9.85v2_op6.zip those are the twrp to use.
Use blu spark twrp version.
Also note to you: when you flash through OTA you will loose twrp.
It's better for you to boot to twtp
Flash rom
Flash twrp
Reboot to twrp and flash latest magisk if you want root.
So always after rom flash you flash twrp.

Yep, just flash it like any other ROM. If it doesn't boot, try to Format Data !

1.flash stock rom through twrp then flash twrp zip(optional)
2.select reboot to recovery and factory reset device
I'm TWRP'd and Magisk'd running a custom ROM (Havoc}, but it's a little buggy. I'm looking to flash a stock ROM with the latest OxygenOS, and then maybe use a Magisk module over that.
Can I? And if so, can you point me to the correct custom ROM thread? I see a couple, but not sure which one is flashable, and which one is for restoring the phone to completely stock (removing TWRP, etc.).
I suggest using this: https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424

I don't think you can flash a stock ROM, and keep TWRP without flashing TWRP again. TWRP will always be removed when flashing a stock ROM, since recovery doesn't reside on it's own partition for this device, but rather is on boot.img, which by definition needs to be flashed with the ROM (contains the kernel).
AFAIK, you will need to flash the stock ROM then flash TWRP and Magisk again. To do that, fastboot flash the above linked stock ROM, then fastboot boot TWRP.img, then in TWRP flash TWRP installer zip and flash Magisk. Wouldn't take long to do, just have the TWRP zip and Magisk zip on the phone ready to go, before you flash the stock ROM.

This works for me
Fastboot boot into TWRP,, ( TWRP nebrassy edition)
install trwp via advance settings
reboot into recovery
send a copy of your ota oos over to your phone ,
flash oss ,
reboot into oss recovery
Format data in oss stock recovery
Reboot
just find a way to relock your bootloader, it will revert you to stock completely.
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.
