Need help flashing OOS 5.1.8 zip (via twrp!?) bear with me.

New OP6 owner, quite bugged with how this thing works when flashing stuff..
it was a breeze on my 6p, anyways.
i decided to do a "Clean" flash and wiped data/system/dalvik etc.
then tried to flash the Full zip of 5.1.8 (it is a 1.2gb file) and i flashed via TWRP then flashed twrp zip and rebooted recovery/flashed magisk.
but there is no OS installed it says, boots me back into twrp.
my question now is how do i get it back to load up OOS, do i have to use fastboot now .. ?
i dont want it to wipe my whole SD
what do i do, and how do i stop this from happening for next time?
i thought flashing was normal that way, are we not supposed to wipe system with the op phones..?
i had a MOD installed (xXx) and wanted it removed so that i could install another mod ,thus i wiped system/data etc.
please let me know how to fix this, thx !

You need to make sure you are booting the slot you flashed the rom on, A or B.

how do i do this? i only flashed zip from the root of my SD , there was no option to select either A or B :C
i went into advanced or seomthing and saw SLot a and B i tapped a and reboot sytem now it is stuck on twrp logo.
f** this ab ****.

When u flashed the rom and rebooted it should let u know which one u r flashing on when u flash magisk, the xXx should have been a magisk module so should have been deleted when u wiped data, I would re-download 5.1.8
Wipe all again.
Flash OS
Flash twrp installer
Reboot to twrp
Flash magisk and reboot

Did u have the magisk module version of xXx, if so all u had to do was uncheck it and reboot

OnePlus 6 has two partitions like the Pixel 2. For seamless OTA updates. In TWRP go to the Reboot menu and you'll see your currently active slot. It's either A or B. Switch to the other one and reboot. That should do it if you did flash the ROM.

man screw this ab partition shet, i will be forced to do a userdata reset..
can you please advise me what not to do to get into this mess again..?
its not fun recopying my data back and forth.
all i tried to do was clean flash and flash the latest rom via twrp..
why does this thing has to be so complex, please tell me if a clean wipe does this mess ?
cant we safely clean wipe this thing or what?
i love the phone, but the flashing stuff is a huge mess imo.

You can always just keep a backup of userdata in TWRP but you don't have to wipe data. If you wipe system and flash the full zip, you will get the no os error but you can boot to system anyway. It just thinks there is no os. The bootloop to TWRP is probably related to magisk.

It's relatively easy. Just always remember to flash TWRP and magisk after flashing full ROM zip. It's always a safe bet to erase your lock screen before messing with TWRP as well so it can just decrypt with no password. If you use a magisk ROM, it's all systemless so the only changes that would stay are the ones that would debloat apps or remove system files. Everything would revert back to normal after you uncheck the ROM module in magisk manager.

hmm okay thx, someone suggested me omni rom, but i will need to erase data right?
but my issue is, if in case i wanted to go back to OOS, would i need to erase data again? :l
and also about flashing roms, must they be flashed on both slots..? a and b ?
i have no clue how i got OOS back booting to be honest.. :l

Switching ROMs, it is best to erase data or keep separate data backups for each ROM and restore the associated ones. As far as flashing on both slots, it wouldn't hurt, but it's not necessary unless instructions dictate. The whole reason for the slots is to allow seamless updates while the os is still active. If you experience any issues with bugs that aren't stated to be in the ROM thread, a clean install is always recommended.

thx mate, so for next time if i were to flash some oos through twrp, i only need to wipe data/cache etc.
then flash the oos zip ? i dont think i had the option to select which Slot to flash it to, so i guess i just have to reboot to the slot that it has it flashed on..?
and also flashing procedure must be like Rom then twrp then reboot twrp then flash magisk yes?

This is what happened to me LOL and I soft bricked phone. Never ever bricked a phone before.
I tried to flash havoc os, OOS was originally on both A and B.
This process wiped slot B clean (even tho was booting on slot A), and OOS stayed on slot A.
I went to the reboot screen to reboot recovery on slot B and BAM I was bricked locked into fastboot mode.
And people say its easy.
Now I am in msmdownloadtool, I have managed to get it connected, and I can start the recovery but it fails, so I think the phone may be proper bricked.
Anyone getting a oneplus6 I would say these phones seem to have a genuine risk of brick, all I did was try to boot of a slot which TWRP says had no OS and now I have this problem.

Havoc OS requires Oxygen OOS in both slots.
So I need to somehow get this to work.
I can unbrick the phone now with msmdownloadtool.
After ubricked the bootloader is locked again so I have to start from scratch.
Unlock oem loader in OS
Unlock bootloader in fastboot
Copy zips to phone.
Boot into TWRP and install TWRP, it says it installs to both slots but B bricks phone.
At this point I have oxygen OOS installed via recovery tool on slot A, twrp installed.
If I try to boot in slot B, phone bricks, fastboot loop which doesnt allow you to boot back into twrp so cannot switch back to slot A without msmdownload tool.
So the question is after I have recovered the phone how do I get oxygen OOS onto slot B as well, given I Cannot boot from slot B?
The solution is probably easy to those who know how but seems it isnt documented.

Fastboot boot recovery. Img
Flash oos full ROM zip

Flash magisk if you want root.
Make sure your using the correct twrp aswell. I recommend bluespark v86

it is not easy, i make backups of my whole phone every 2weeks because i am a flashaholic i see myself switching from aosp back to oos and vice versa (i love oos) i actually gave up on flashing roms some weeks ago tried to stick to oos only so that i wont be bothered with bricks for whatver reason (and not being forced to use msmtool) , it is frustrating.
you always have to make sure you are not flashing a rom that has an older security patch , e.g november build of oos if you flash aosp rom with october build you might brick, so the rom has to be either on november security patch or newer e.g december.
it is so confusing as you even have to use the latest twrp always or else you can mess it up again..
always make backups is my advice.

If you're installing havoc os, make sure you're using latest bluespark TWRP first. Reboot recovery, flash oos, flash TWRP, reboot recovery, flash havoc gapps and magisk then reboot. The only difference in a/b partition is that there's a few extra steps in the flashing process. You don't have to flash to both slots to have havoc, but you also shouldn't be manually changing the slot in TWRP to try to boot a specific slot unless you know what you're doing.

Can't install custom ROMs. Help!!!

Few days earlier I had to use MSM tool as my OP6 only went to Crash Dump mode everytime.
So after flashing the tool, everything went back to normal, but since then I can't get any custom ROM to install on my phone. whenever I do flash the rom and then twrp, I reboot to recovery for flashing gapps, it takes me to fastboot mode instead and never boots.
Evidently, I have installed Omni, Havoc and all the other roms before. What can the problem be? Any help please?

I supposed you read the instructions and flashed to both slots? Or did you do like most and skip a few steps?

Hi!
I am in the same situation : MSM tool and then I can no longer install custom rom. Have you resolved the problem ?
Thanks !

Did you flash oos to both slots? Like the comment above yours tells him to.

People need to read. This already been discussed over and over.

I didn't understand in the previous post that it is OOS that need to be flash twice, not the custom rom. Thanks whizeguy !

The OP6 is my first device with this A / B. I read a lot about this A / B and I think I understand it. But I'm going to install this ROM https://forum.xda-developers.com/o...eally so stupid? Can some one help me please?

Have you tried the new Blue Spark TWRP?

If i boot in to twrp, flash the rom and twrp, go to reboot -> recovery: the screen stays black and does not reboot in to recovery.
I tried twrp-3.2.3-1-enchilada and twrp-3.2.3-x_blu_spark_v9.86_op6
After hours of trying, the phone booted one time the new rom. Now i'm back on the stock rom, because OP of the ROM listed features which are not included.

Has anyone been able to boot a TWRP restore on this phone?

I break my system a lot (currently testing which of my favorite Xposed modules work with Pie) . I've had to set up from scratch like 6 times in the past week. Every TWRP restore results in a boot loop, both custom and stock. Has anyone made it work and, if so, how? It surprises me that our TWRP is official if it can't restore a backup.

Encrypted?

I'm having the same problem. This is my first a/b device and everything I thought I knew after flashing ROMs for years just doesn't seem to work on this architecture. Like you said twrp backup restore always results in a bootloop. Also any full custom ROMs I've tried appear to overwrite twrp and install its own recovery. Even gsi's don't boot and then twrp freezes and back to stock I go. This thing has me stumped.

I noticed when installing RR that it actually needs that Lineage recovery to factory reset after the install. A TWRP factory reset wouldn't help it, and it wouldn"t boot after the install. Funny how they try so hard to stop us tinkerers, then steal all our cool ideas for their stock ROMs. I see Linux phones in my future.

I wonder if a factory reset with that Lineage recovery would help after a TWRP restore? Next time I may try that.

Damn! I just got it. I'm typing this on a restored crDroid Official. The boot.img is in ramdisk, so only backup system and data. Yay!

So your saying because recovery is in the boot image that we need only to backup system and data and then a restore of same will not go into a bootloop? That would mean the problem has been backing up and then restoring the boot image. System as root and no recovery partition is just hard to grasp at this point. For me restoring data in a backup of stock results in twrp error 255.

I spoke too soon. This was the 1st time I'd flashed dm-verity on the install. That's why it worked. It won't work if /data is encrypted. I just made a backup with boot as well and it restored fine.

I'm not sure where I got it Or else I would link you. But this is the one I'm using this one. I flashed it after formatting /data and also after installing the ROM. One of those is proper, but I couldn't remember. I think it's supposed to be after you install, but before 1st boot.

That's the same one I've been using. So crdroid actually booted for you after doing a normal wipe in TWRP?. Assuming you had stock pie installed.

Yup. I've restored it twice and made another with boot included and it booted as well. I hope it works with RR too, but I've got a helluva headache. I may stop messing with it for now.

Oh, I had wiped dalvic (actually ART), system, and data. I don't think boot was an option during wipe.

You know, I've only had one device before thar force encrypted, and back then, TWRP couldn't decrypt /data except by formatting. Now it can. That's why I didn't suspect it was an encryption issue.

I was still using a Galaxy S5 with crDroid 7.1.2 built by me until last week. It died, may it rest in peace.

If, when you boot TWRP, it asks you to decrypt, dm-verity didn't work, and it might not work with stock. I'm only figuring it out at the moment.

My goal was to have twrp backup of stock pie which is really great in my opinion and also be able to flash Q gsi's like I do on my Moto g6. So far any backup restore of stock just bootloops and any gsi just hangs at boot logo or boots back to recovery.

It does appear to be an encryption issue with a stock rom TWRP backup restore not booting. Formatting data in TWRP and rebooting always results in a bootloop. Until I can format data to remove encryption and get it to boot and the security setting says it's not encrypted, I don't think a backup will ever boot. Out of ideas at this point.

For stock, I wonder if you could boot TWRP after all those fastboot commands and flash dm-verity before booting stock. You may be able to keep stock from encrypting. I don't know for sure though.

Oneplus 7 Pro Bootloop after overlay install, still booting into recovery

Hi guys. Really need your help. Oneplus 7pro ,european version running 10.0.4 software, latest magisk 20.4 i think? and twrp. Everything was running fine until earlier when I installed a system ui overlay (one i've used before) and now my phone is in a boot loop. I can access TWRP, I've run the substratum overlay uninstaller zip and removed all magisk modules but still i'm in a bootloop. I've never had a proper bootloop before and i'm very frustrated. I've googled for the past few hours and removed everything I can think of that could be causing issues. Does anyone have some advice that doesn't end with me losing all my data? I have a backup but its from a month ago. I've never had this issue before so i'm a little stuck. Thanks
Edit. Phone is fully accessible through my laptop I can see all my files and connect to it. I just cannot get it to boot,surely its a simple fix?

Hi,yes I can. Its loading the logo now so i'll wait and see what happens. If that works then what should be the next thing I do?
Edit: Slot B seems to be bootlooping on the logo unless its meant to take a few minutes
Is there a way to recover without wiping my data?
So slot A sits on the caution device rooted screen then defaults to the fastboot rescue mode which allows me to select reboot to recovery which is twrp. From there I have full access to the phone but still not booting to system. Slot B passes the fastboot screen and hangs on the one plus logo just circling around. This is my first rooted phone and I haven't had any problems until now so I'm hoping its something simple because I didnt do anything big to cause it. Hopefully someone has some insight.

Can I just sideload the current version of OOS i'm running using TWRP and not lose my data?

Will I lost root or relock the bootloader? I'm trying to find the least destructive way to get back to what I had which was oos 10 with twrp and magisk.

Uninstalled magisk and was able to reboot. However reflashing it as i want to retain root makes it bootloop again. Any possible fix for this that isn't a factory reset and reroot?

I can't get substratum or substratum themes to work on any rom or stock, nothing happens after reboots.....or everything turns this weird orange theme. Then one time it corrupted the whole OS and I had to wipe.

Thanks, i'll try this. Will I need to install TWRP again once I do this or is it unaffected?

Tried to dirty flash the same stock rom from TWRP but I don't think it did it properly. Can I dirty flash stock rom, flash magisk then try reboot to system?
Any help greatly appreciated.

Has anyone successfully restored with TWRP?

I've been using Beta 19 OOS with all of my apps configured for quite a while now. But, I'd like to try some custom roms. If I don't end up caring for the custom roms, I'd like to easily restore back to OOS Beta with all of my apps. I've never tried a full restore with TWRP. Does it work successfully? Are there any "gotchas" that I should know about?

Yeah, I did it over the weekend.
Tried crdroid and lineage Android 11. Ran into some issues and was fed up.
I don't think you can fully restore photos and music and so on on your internal storage, so I backed up mine.
My steps were:
In twrp, format device,
Reboot to bootloader and reflash twrp using adb.
Reboot to twrp and copy over twrp installer, oos beta19 and Magisk.
Flash Oos beta 19,
Flash twrp installer,
Flash Magisk,
Reboot to twrp
Flash Magisk,
Reboot to system.
Your device will then be on stock oos 19 and start the setup process. You don't have to complete it, so just skip all the steps. When you can, restart to twrp and use the restore functionality.
Everything should then be as it was when you made the backup, except for the music and videos I think.

Yeah, I did it over the weekend.
Tried crdroid and lineage Android 11. Ran into some issues and was fed up.
I don't think you can fully restore photos and music and so on on your internal storage, so I backed up mine.
My steps were:
In twrp, format device,
Reboot to bootloader and reflash twrp using adb.
Reboot to twrp and copy over twrp installer, oos beta19 and Magisk.
Flash Oos beta 19,
Flash twrp installer,
Flash Magisk,
Reboot to twrp

I couldn't get lineage 18.1 working with Magisk and Twrp.
Crdroid I could use for a while, but when I tried to update it, my phone would only boot to Twrp.

Which method did you use for updating crdroid? OTA or flashing from TWRP?

Ota.
When I rebooted I was dropped into lineages' recovery mode! Wtf

When you first went from OOS to custom rom, where you able to restore your apps and settings from TWRP, or did you have to start fresh?

I started fresh.
I think you can backup app settings with titanium backup, and just restore it on the new rom.

Yeah, that's my biggest concern. I don't want to have to reinstall and reconfigure all of my apps.

Try it and see how it goes. Make a Twrp backup and a titanium backup. Copy those files to a pc or something.
If you install a rom and you see the titanium backup isn't restoring all your apps, go back to OOS and restore using Twrp. You'll have your phone in the same state as when you started, only now with the benefit of experience.
