So I'm bootloader unlocked for 10.0.0.1 I'm about to update to 10.0.3.
Everytime I try to flash recovery or boot recovery with twrp it doesn't work.
If I load it via magisk it works sometime but other times causes bootloops.
My biggest issue is booting/flashing twrp and When I flash a custom rom.
It says to flash on A and B. Sometime I can flash to one but when u change to other slot it wolnt flash or it'll show like it's encrypted any help? I've been on basic OS with NoLimits but now I wanna do kernel, rom flashing etc. Help?
If you want to update from .1 to .3 just do this(keeping in mind that you already had twrp and magisk)
Put update.zip in your internal storage
Go to settings>system>updates>local upgrade
Select update and install
Wait to finish but DONT REBOOT
go to magisk and install twrp installer(I use V3.3.1-74)
Then install magisk to inactive slot(after ota)
Reboot and that's it!
You can install custom kernel from twrp or fk kernel or any other app
If you want to install a rom you had to install to both slots(keep in mind that ROMs always be installed on inactive slot)
So make a factory reset(default by twrp wipes data and dalvik)
Install your rom and don't reboot(example if you are on A slot it will be installed to B)
Install twrp installer
Reboot to recovery( this will change slots A to B for example)
Install your rom (slot B to A and you will have your rom in both slots right?)
Again install twrp installer
Reboot to recovery
Flash gapps( if rom don't have it) magisk and kernel I personally recommend to flash after first boot
EDIT:
And another thing, if you get your internal storage encrypted and you can't access your rom,gapps,magisk you can always use adb sideload:
In your platform tools folder put your rom,magisk, etc and in twrp go to advanced>adb sideload and swipe to initiate.
In your command window use this:
adb sideload <nameofyourfile.zip>
Example: adb sideload magisk.zip
This will transfer and install magisk, ROMs and gapps

Here's the hinge on the rom right? Install on slot in recovery OK good got it. Reboot recovery try to install on other slot there is nothing on phone or its encrypted.

Hi
In every rom thread I see about a million different answers on how to properly install the rom. Usually the official instructions are very vague. I've been flashing roms for years but this ab partition is very confusing to me. I just got my oneplus 6 a few days ago. It would be great if someone very knowledgeable in how to do this could make a how to guide for both stock and custom roms. I think it would really help everyone and threads for each rom wouldn't be full of people asking it over and over (and getting different answers). Thank you devs for all that you do.
Custom if you don't know if you have the recommend base installed to both slots:
Flash OOS
Flash twrp
Reboot to twrp
Flash OOS
Flash twrp
Reboot to twrp
Wipe data, dalvik cache
Flash custom
Flash twrp
Reboot to twrp
Flash gapps
Flash magisk
Boot system
Custom update:
Flash updated custom rom
Flash twrp
Reboot to twrp
Flash gapps (not needed, but updated gapps is most likely better to use anyhow..)
Flash magisk.
From custom back to OOS:
Info: Format data needed because you will trigger encryptionsince you're on different securety patch. This is also the same way to go from beta branch of oos to stable since the securety patches is lower (in general) on stable.
How to:
Boot twrp
Plug phone in to pc and take backup of everything
When done format data
Transfer oos, twrp, magisk to phone
Flash oos
Flash twrp
Reboot to twrp
Flash magisk
Update oos from... Let's say 9.0.4 to 9.0.5
From Twrp:
Flash oos
Flash twrp
Reboot to twrp
Flash magisk
Boot
From oos:
Use ota update, let it install until it asks you to reboot.. DON'T DO IT.
instead go to magisk and search for "a/b" one module will be found, install it. DON'T REBOOT
Go to main screen of magisk and press install, install, install to inactive slot (after ota) when it's done you can reboot.
General ****ups:
Don't boot after update?
Flash magisk uninstaller
Try to boot (yes.. Without magisk)
If it boots you know it was magisk issue, most likely you had substratum overlays installed or modules that messed it up.
Reboot to twrp and flash magisk again and set up your modules one by one or apply themes or whatever you do with your root.
Hello xda-comunity
I'm unable to install the oxygenos update 9.5.8 GM21BA
So I was following this guide to unlock my bootloader and root my phone with magisk.
( https://www.google.com/amp/s/www.xda-developers.com/unlock-bootloader-root-oneplus-7-pro/amp/ )
All went well. I got the notification that there is a new update (see above)
In the guide there was a step - by - step instruction on how to update the phone and keep root. I did that.
And now when try to install the update I get a bootloop into recovery. I figured out that the op7pro is a 2 slot phone ( slot a, slot b) and when I install a update it sets the for example slot b (where the update is installed) as default.
So when something goes wrong it just loads up the "previous" slot (in this example slot a) as default again and says that the update failed to install. Correct me if I'm wrong .
And now to the my problem, the phone doesn't load on slot b nor does it default back to slot a, instead I get a recovery bootloop when I'm in slot b.
The fix here is to flash twrp via fastboot and load slot a again, my phone then boots up like normal.
And here is the problem I can't install the update because I probably messed up slot b.
I know it's a long post and I appreciate every possible answer. Thanks in advance.

Thanks for the quick response I will try that as soon as I'm home from work. How do I find the ota? Can I download it? Or is it saves in a folder on the phone? Because I downloaded it like 3 times now.

You can drag the files back into the root of your phone and flash them on the other slot. You could ADB fastboot but just dragging the zips to your phone is easier in my opinion.

Sorry if Iam stupid but is that how it works?
I flash the zips on slot a then reboot to boot into slot b to flash it there again?
Because I dont get it, am I missing something here?
Edit: Seems like I Bootloop into recovery on slot b.

Yes you flash on both slots. If youve already flashed both then flash magisk and reboot to system. It should take about 10min to boot so dont worry.
Edit: If youre getting a bootloop or having bugs then follow this https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-f to get back to stock international
Then follow https://forum.xda-developers.com/on...nt/recovery-unofficial-twrp-recovery-t3931322 then flash Magisk and reboot
This is ONLY if you cannot get it to boot after updating

I dont know how to put files on slot b.
When I switch slots I have to reboot.

Alright i flashed the ROM new
Was able to install the newest ota just perfect.
Kept it unrooted, I think I'm gonna let it unrooted because of all the work I have to do Everytime a new ota comes (maybe later when the phone is older)
Thank you so much for your help.
I am on 9.5.11 at the moment. I am rooted with magisk but don't have twrp at the moment. What are the correct steps to go to full stock android 10 and then root the phone again (either with twrp or not. Doesn't matter)?
I am downloading android 10 full rom as I am writing this post.

You can't flash twrp on Android 10. You have to have twrp while in P and then carry it over to Q.
Or flash a patched magisk boot.img then flash twrp installer in magisk manager.
Easiest is to do a local upgrade and flash twrp rentension zip and then install magisk to other slot and reboot system
After that, you can reboot into twrp and do a factory reset to have a fresh install of Q.

So...
1. Install twrp
2. Flash android 10 full rom .zip
3. While still in twrp install twrp retention zip
4. Flash magisk as it is
5. Boot to system
6. Go back to twrp and then go: wipe-format data-yes
7. Restart and phone should boot up normally
8. Go back to twrp and install magisk to gain root again
Correct?

First, do u currently have twrp?
If you do then:
1. Flash the Android 10 through local upgrade
2. Then in magisk flash twrp rentension module
3. Then in magisk, click install and install it to other slot
4. Reboot system
5. After booting into system, reboot to recovery
6. Do a factory reset in twrp and reboot into system
7. Go through setup.
Hello Android developers and enthusiasts,
I've been installing ROM since 2011 so I would not call myself a n00b however I seemingly cannot install an Android 10 ROM without issues. So this is a plea for help and advice!
I know you need to have OOS installed before you install a custom ROM so I use Auto Flash ROM to install OOS with Android 9 via System Update. I then boot and set up phone, install update, reboot and then install the OOS android 10 via the System Update. I then have a OOS installed with Android 10.
Why would I use such an elaborate method you may ask? Well, I tried to download latest OOS from OnePlus site and wipe phone and then install OOS but that fails (didn't record the error I'm afraid).
I then download all the ROM + dependencies on an USB stick and use fastboot to flash Mauronofrio TWRP. I then follow the steps in the ROM instructions. For EvolutionX these were:
First Time Install / Clean Flash
- Have OOS 10.3 flashed to both slots!!
- Boot to recovery
- Flash BUILD.zip (TWRP built-in)
- Wipe Cache
- Format data
- Reboot to recovery (optional)
- Flash Magisk.zip (optional)
- Reboot to system & #KeepEvolving
Click to expand...
Click to collapse
I followed these to the letter but when i rebooted system I got a snapdragon error and it wouldn't even boot into TWRP until I used fastboot to flash boot into TWRP. I also tried HavocROM and same happened.
I did manage to install Syberia using above method but I didn't like the ROM that much unfortunately.
Finally, I've also read up a lot on Slot A and B but it still is not very clear to me. I think I understand it but what happens does not confirm my theories
I therefore have some questions:
- Should I be able to wipe my phone and install OOS on a wiped phone and then install a custom ROM?
- When I install ROM and it says "Reboot Recovery" and then install ROM again. But if I check what slot is being used the reboot doesn't seem to change the slot. My assumption was that booting recovery was to install ROM in the other slot. Is that correct?
Any other tips you can give me?
Again, I like to stress I am not new to installing custom ROMs so I am a bit disappointed that this is causing me such grief.
Following some answers I will retry tomorrow so I can give some more details if needed. For now, appreciate any help.

Hi!
I had this exact same problem a couple months ago. Rebooting to recovery used to change slots for me, but then it stopped.
What you can do is change active slot manually on Reboot section. By doing this, you don't even have to reboot to recovery in other to flash the other slot (altough I do it just to be safe).
And remember: the rom is flashed on the inactive slot, so after the final flash you gotta change slots one more time.
When you flash one ROM on top of another different ROM, particularly OOS to custom, always wipe data and not format data, because some custom ROMs do not support being unencrypted in the first time and then encrypt on the first boot. So do it like this:
Flash OOS
Flash TWRP
Reboot recovery
Flash OOS
Flash TWRP
Reboot system
Complete initial setup
Reboot to recovery
Wipe (not format) data
Flash custom ROM (start here for dirty flashing ROM update)
Flash TWRP
Reboot recovery
Flash custom ROM
Flash TWRP
Reboot recovery
Flash Magisk
Reboot system
I don't like built-in TWRP in custom ROMs. I always use @mauronofrio's TWRP. So regardless if the custom ROM I'm using has TWRP built-in or not, I always use the method above. I didn't have a problem with installing ROMs using his TWRP. Slots always switch when flashing ROM.
Thanks for the info, it really helps.
One question: in your experience can you wipe your phone and then installl OOS on the wiped phone?
So I just booted into TWRP, did standard wipe action: Data, Cache, and Dalvik. I then try to flash the latest OOS zip and I then get this error:
Error applying update: 7 (ErrorCode::kInstallDeviceOpenError)
Updater process ended withL ERROR: 1.
Error installing zip file: '/usbstorage/00, INSTALL/OnePlus6Oxygen_22_OTA_044_all_2002220042_a46425f1bfe43d2.zip
FIXED: I was using TWRP 3.3.1.11 and I then found out there was a newer version: 3.3.1.18 which you can get here: https://sourceforge.net/projects/mauronofrio-twrp/files/Enchilada/
I am now able to install OOS from scratch (ie wiped phone).

I tried this method and everytime I can't seem to flash oos onto the other slot because when it reboots to recovery the folder is encrypted so I can't see which file is the zip. How do I flash the seccond OOS if it shows up encrypted in TWRP.
I have a OnePLus 6 with the latest OOS now because I got into boot loop and i used a flash-all.bat to get back to stock. I also use maronofrio's twrp because that works.

If you can boot OOS fine, try to do a local update so that both slots have OOS. Then try to flash a custom ROM again using the method I've mentioned.

When you say local update you mean while I am running the rom, go to settings then do update from local source?

How do you choose slot b while flashing on TWRP?
This seems really convoluted to me, but it totally worked:
Boot TWRP (from fastboot)
Install TWRP from phone storage
Reboot into recovery
Install ROM, gApps, TWRP, and Magisk
reboot into recovery
Install ROM, gApps, TWRP, and Magisk
reboot into system and wait for something like 5 minutes while it sat on the "Your bootloader is unlocked!" screen.
I believe that installed into both slots for me.
I also had to ADB push the install files after the first ROM install because my encrypted data all got lost. This was all SUPER inconvenient, but it ended up working for me.
