hello mate
and when i install Rom, do i need to install on both slots or i can have one has backup (its what i have been doing till now)?
and when i factory reset, what will i lose?

Well, it is difficult to say. Usually, every ROM has its thread, its instructions and its community that helps with problems related to installing that ROM.
It could be a few things:
1) I do not see any mention about wiping data. Usually you need to wipe data and wipe system partition in twrp before you install a new ROM. Maybe that is the issue. However, what you need to wipe is ROM specific.
2) Check prerequisites, what ROM version you need to be running before you flash. Sometimes that matters.
3) OnePlus 6 has these A/B slots that I do not fully understand. From what I have read, if you are running on slot A, update installs on slot B, and then you reboot to slot B and cycle continues. BUT DO NOT TRUST ME ON THIS. You should read yourself. Anyway, sometimes people recommend flashing both slots A and B. For some ROMs. For LineageOS, for example, that is not necessary.

oh, factory reset damn i would want to configure everything again

I think first.
You have to WIPE data, all. Factory wipe option.
Then boot into twrp
First, flash OOS, followed by TWRP
Reboot to Recovery using twrp itself.
And then again flash OOS and TWRP.
Reboot to recovery again (using the option in twrp itself)
Finally, then install your rom followed by gapps etc etc
Then it should work....

is there anyway to do this without factory reset?

no

NO OS Found IN ONEPLUS 6

Hi Team,
Today i was flashing custom os in oneplus 6 via one youtuber videos
He has selected TWRP wipe menu
Advance -> system , data , Davic/ cache
i did same then he installed the os i also did the same and flash twrp
After doing roboot the system TWRP given me error no os was installed i ignored that message and proceed to next
After system was rebooted im only getting fastboot mode and no other options also im unable to install now any TWRP in my system
can some one help me please

Maybe try format data.
Go to wipe then advance wipe and format data.
If it doesnt work then use msmtool to go back to stock rom and start again.

Don't trust every YT videos you see, NEVER wipe system on op6 or you get this result.
Now you can reinstall TWRP from fastboot and reflash stock OOS twice, if it did not work try to flash stock fastboot firmware

here is a simple solution..
Reboot Recovery
Wipe Data, System, Cache
Flash OOS & TWRP
Reboot into recovery (Ignore No OS Installed Warning)
Flash OOS & TWRP Again
Reboot
Done
if you want to Flash Custom ROM, Here is guide
Reboot Recovery
Wipe Data, System, Cache
Flash OOS & TWRP
Reboot into recovery (Ignore No OS Installed Warning)
Flash OOS & TWRP Again
Reboot into Recovery
Flash Custom ROM & TWRP
Reboot into Recovery
Flash Gapps, Magisk Latest & No-Varity zip is had data decrypted
Reboot
Done

Any reason why we shouldn't delete system partition in op6?
Sent from my ONEPLUS A6000 using XDA Labs

The system also holds the recovery....i made that mistake once and i had to use MSM tool to restore my phone. Big waste of my time to a dumb mistake.

custom rom update

boot twrp
wipe system and dalvik
change slot
wipe system and dalvik
reboot recovery
flash rom
flash twrp installer
change slot
reboot recovery
flash gapps magisk etc.
reboot system
this method blongs to TogoFire

Correct Procedure

Hey guys
Just need to know correct Procedure. Im currently on Syberia Rom (Android 12)
I want to go down to a Rom (Android 11)
Do i have the procedure right
Boot into Twrp
Wipe Cache, Data, Davlik
Flash OOS (latest build)
Boot to TWRP
Flash New Rom
Boot to TWRP
Flash Gapps
Flash Magisk
Wipe Data
Reboot system
Would that be the correct process?
Thanks

I wouldn't bother with TWRP. I'd use the MSM tool. Sorry, I'm a bit busy, maybe others can chime in here.
