firiends can i directly flash lineage os 15 to lineage os14.1 or lower via twrp .. i mean is downgrade is possible by simply twrp installation
Clean flash is always recommended... While switching one ROM to Another ROM and nought to Oreo ROM and vice versa

Lineage based is fine, I was on 15.1 official , then switched to Aex with same twrp with no problem whatsoever.
thnks fr ur reply.i installed lineage without changing it to ext4.so my doubt is if i have to change it frm f2f to ext4,can i use lineage based twrp to format data or i have to switch back to original twrp to do the process.

Lineage based causes issue with formatting data many a times. But in my case if u first change data to ext4 ,then wipe data then all is fine.
But users have also reported bootloops and decryption issues with formatting data with LOS twrp. So for safety, formatting data with official twrp is best but in my case former worked for me.
Hi
I'm currently on crdroid . can i flash los or aex with dirty flash?

Man, dont dirty flash one rom over other. The pain of clean flash is way less than dirty flash with problems.

I couldn't get the Lineage OS TWRP to work as it couldn't mount the data partition even though it re-formated it to ext4.
Official TWRP worked first time.
Hope this helps.
Good luck!
guys, i have a little confusion:
What's the correct procedure for reinstall the stock OOS from a custom rom and the procedure for change custom rom to another one?
i ask this because every time i try i brick the phone. (so msmntool and lose internal storage)
my latest experiment:
i was on Havoc, rooted and blue_twrp
full wiped (cache's, data and system)
installed Full 9.0 OTA+ twrp on slot A
rebooted to twrp
installed again Full 9.0 OTA+ twrp on slot B
installed magisk
rebooted to system...
keep boot on recovery and also i canno't decrypt sdcard because twrp doesn't ask me the pin....
someone suggested to me to format data, but i don't want to lose my internal storage anytime...
help?
The best thing to do to avoid all of thi bs is to follow this guide:

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:

Thanks so much!
Hi there, can someone enlighten me how yo flash custom roms?my device already unlocked bootloader and i know how to flash cuz i play with xiaomi mi5, sams galaxy3 , sony x8.
For now i dont have a twrp. Im going twrp by fastboot before this.
Im really sure that i already go through all of the post. But seems from OB10 is really complicated.
1.ready fastboot twrp, bluspark twrp,roms, gapps and magisk( if necessary) and custom kernel
2.fastboot twrp by cmd or else
3.wipe what here? Or just factory reset and leave internal storage?
*Here i confused, do i need to wipe for both slot. Im still new to a/b partition. And do i need to do that for both slot to flash as steps 4-10 as below?
4.flash roms then bluspark twrp
5.reboot to recovery
6.flash gapps,magisk? Then twrp back?
7.reboot to twrp
8.flash custom kernel then twrp again?
9.reboot system
10. End right?
Please help me here. I cant find the real and proper steps. The only way i found is from OB7 to custom roms as they share same security patch.
Thanks for any help.
1. Flash any strock rom.zip partition A.
2. After that recovery.zip
3. Reboot back to recovery
4. Confirm you are in another slot B
5. Flash stock rom.zip. Which slot first is not important.
6. After that flash recovery.zip and then reboot.
After that you can install whatever you want.
That what I do if im switching roms and trying new stuff.
Working everytime.
Until OB7 and stable 9.0.2 I used fasboot roms, flashed via AIO tool, but new fastboot roms working different and I got laggy video and audio.
Okeh thats clear for both slot. But for OB10 to any customs rom is it needed to flash OB7?
What do you mean by stock rom?bete rom or stable rom?

Stock any offical rom for OP6
9.0.2 or 9.0.3 or any OB3,4,5,6,7,8,9,10
If you want custom rom, look instructions, there is mentioned what is base rom. That you need flash.
If there is custom rom based OB7 then you need flash OB7(probably working lower builds also)
Thank brotha. I think they need to state which firmware do we need to start from. Otherwise it will be like me that confusing as they will patch up more and more security.

Pie ROM, pie firmware. (Except pre release betas)
Oreo ROM, Oreo firmware.
ROM - always flash latest firmware of the OS you want pie or Oreo (I always go for latest and don't have any issues . Tho I'm back to oos ,debloated now.)
Twrp - Always after ROMs, before roboot.
Gapps - after twrp and reboot, to make sure it installs to the right slot, that's why you install twrp and then reboot.. this will change your slot from A to B or from B to A. Manual switch is never necessary
Flashing gapps flashes to the slot you are in right now, so flashing before the first reboot (after twrp flash) Will get it to the wrong slot.
Magisk - if you want root. After all.
After all this you can, if you want, flash decrypt ..if you don't need your device to be encrypted,this Will give you more to think of tho.. let's just not go into this now.
i understand the process, but get confused at which file to specifically flash twice when they say
"latest firmware of the OS". So lets say the custom ROM i want to flash needs a PIE firmware 9.0.2 or higher,
what file am i supposed to flash?
9.0.2-PIE-OnePlus6Oxygen_22_OTA_027_all_1810260000_d46787d2c9-FASTBOOT.zip
or
OnePlus6Oxygen_22_OTA_027_all_1810260000_d46787d2c9.zip
Hi!, i installled Oreo on my S7 g930f but i now have one problem. The ROM binary from oreo is 3, and Nougat use 2, for this reason i cannot to downgrade to nougat. Recently i installed TWRP and a custom Oreo rom.
Its possible to install a custom Nougat rom through TWRP?
Many Thanks!
You should be able to flash a Nougat ROM via TWRP, but you'll have to make sure to flash the bootloader and modem back to Nougat if the ROM doesn't include it as part of its install.
I've gone between Oreo and Nougat a few times, granted my roll backs were using a TWRP backup and not a nougat flash.

Have you some tutorial teaching how to make this downgrade.
After the update my mobile is Just Call of Emergency, and the patch to solve this just works at Nougat.
Hello,
Right now I am on havoc OS on my tulip. I want to clean flash miui 10 . How can I do that safely using miflash tool? I had heard somewhere that I can only flash back to that exact version from where I flashed custom ROM?
Please help me as I am new to arb and it really confuses me
Download the latest stable build.
http://bigota.d.miui.com/V10.2.2.0....roGlobal_V10.2.2.0.OEKMIXM_5af4a46864_8.1.zip
Then just flash it with TWRP (Pitchblack is recommended) like you would any ROM.
