The included LineageOS recovery text is very small.
EDIT: Installed open_gapps-arm64-10.0-nano-20200603.zip using adb sideload without errors, but after system boot nothing changed, as if nothing has been installed

Flash magisk after gapps to retain gapps.

Manual of how to install the gapps from the lineage recovery

Flash lineage -> reboot recovery (or fastboot boot twrp again) -> flash gapps
It's an A/B phone people. It's been years.
ROM gets installed to the inactive slot. Addons install to current slot. Slot cannot be changed without rebooting, at least in current twrp.

Why there's a need of magisk? I don't want to be rooted

You use twrp, not the included recovery?
Are you implying gapps survive an OTA upgrade? If yes, please make a for dummies install guide (including the slot change steps)

@mikeioannina , Why is the fingerprint from build.prop so old?
Code:
ro.system.build.fingerprint=xiaomi/jasmine/jasmine_sprout:8.1.0/OPM1.171019.011/V9.6.17.0.ODIMIFE:user/release-keys
ro.build.fingerprint=xiaomi/jasmine/jasmine_sprout:8.1.0/OPM1.171019.011/V9.6.17.0.ODIMIFE:user/release-keys
How can this affect if you came from Android 10 V11.0.10.0QDIMIXM?

Gapps no installing?
Gapps not supported?

Lineage is always without Gapps

Step 6 of the guide specifies how to install Gapps or Magisk.

I write this post only becoz i was not able to install gapps correctly with the rom ,but after lot of try at last i got it.... I provide method from start after u unlock bootloader...
1. Use command "fastboot boot twrp.img" , in fastboot mode
2.boot into twrp ,go to wipe format data than advanced wipe select all option and wipe
3. Transfer your rom ,gapps and mazisk to the sdcard via pc
4. Flash the rom first , than go to reboot option change slot to other one and reboot bootloader
5. Use command "fastboot boot twrp.img"
6. Flash gapps which u want (i use open gapps stock)
7. Flash mazisk (this is necessary) if u want to retain gapps after reboot
8. Now again go to main menu of twrp and wipe>format data
9. Now reboot your system .....
I use this method and got success to boot rom with gapps .....there is various methods but i told only which i applied....may be it will help to the needy one ......sorry for bad English

you don't use the lineage recovery?

I have followed the lineage guide but it installs lineage but without gapps, even though I also install them as the wiki says

If I follow the official wiki method, I have no gapps after boot to system. If I follow vikaseth's method, I can't even boot to system, after a minute or two lineage logo animation my phone ends up in recovery saying data maybe corrupt and I have to format it, but it doesn't help also.
I tried lineage and twrp recovery also. If I combine the two, flash rom from lineage recovery, then flash gapps from twrp, I stuck with endless lineage logo animation.

Another one who has tried the same method for tohers roms to install gapps and no works and also tried lienage wiki and also no works.

Am I the only with a non working recent app button ?

I followed the wiki instructions without problems also updated by OTA and everything is fine. Installed Gapps and Magisk.
I'm very happy with the ROM. Highly recommend.

Works for redmi 6 pro?
i dont get it, i've tried several times to install this twrp.img.
but as soon as i reboot {fastboot boot twrp.img} it just goes into the system, instead of recovery, and then when trying to reboot to recovery its still the xiaomi recovery.
how do i prevent it from constantly replacing the twrp with the standard recovery??
i dont know how to install magisk or the other zip if i even cant get into twrp...

it actually works. Make sure you keep the vol+ button pressed for a while when you do the fastboot boot command.
It will eventually go to a black screen after the mi logo. now wait about one minute and press the volume buttons and twrp suddenly appears!!.
After installing ROM, it got soft-bricked, Had to wipe cache and dalvik again after rebooting, then it worked.

Hello, new Pixel XL owner, previous Nexus 6 owner! Got Qs

I've tried flashing the phone to TWRP, and it sticks...
but when I flash LineageOS 16, it says no space... so I erase the system partition...
flash again and add Opengapps for pie 64bit version...
and it just boots to a lineage recovery page...
I haven't tried other roms, because I just basically want lineageOS, minimal gapps, and google camera basically
I have tried 3 times already, but this A and B partitions got me all worked up... do I have to flash A then do it all again for B partition?
I've had the phone for a week now, I'm staying on Stock Pie at the moment, because I turned off a bunch of stuff and battery drain in quite minimal at least... and I'm quite happy actually...
but I wanna test around roms to see what the community has created for this device.

If still in a quandary here goes ...
Flash per instructions for ROM you're going to use (see ROM OP instructions).
Here is a very basic rundown as compiled from various instructions from ROM's within XDA
1. Make sure you are on the correct vendor for the ROM you want
2. Download the ROM and Gapps
3. Pay attention to what slot stock bootloader is in (A or B) within bootloader window
4. Boot into TWRP Recovery
Remember that TWRP flashes to both slots, the Rom flashes to opposite slot you're in. Try to flash ROM and Gapps
onto same slot original bootloader appears as (in Reboot Menu)
5. Wipe as instructed within ROM instructions -- (clean/dirty?)
6. Flash the ROM (noting slot)
7. Flash TWRP Install Script (Don't forget, this is important to do!)
8. Reboot Recovery (note slot)
Gapps will flash to current boot slot so check and confirm that you are in the slot you want. If not, switch to it and
reboot the recovery again (you can check in Reboot Menu)
9. Flash Gapps
10. Reboot and Setup Device
If rooting, Magisk can be installed after first boot
If needed, with adb you can run this command to swap to A or B "fastboot --set-active=a (or b)"
Hope this helps, remember ... Flash per instructions for ROM you're going to use (see ROM OP instructions).

Hey ! Good job ! I tried building my own TWRP today but then noticed someone already did it ! Does encryption work ? I cant seem to decrypt the partition after flashing your TWRP.
EDIT : Couldn't wait, ended up formatting with encryption disabled via a zip + magisk
I've then proceeded to flash some GSI for Android 9 (even tried Q Beta 3) and if we want 9.0 one day, some heavy work will be needed : Cellular doesn't work; other than that, it all seems fine to me, camera is only 12mpx, front is 13mpx. Haven't tested more, i'm back to stock
EDIT 2: After comparing camera from stock and gsi, GSI wins easily. The camera is not as slow as stock.
Are there any decent ROMs yet for this phone? LineageOS would be fantastic.
@kgoerbig not to my knowledge. Maybe I'll try porting a 9.0 GSI soon.
I'm not sure if this is helpful or not, but Umidigi posts stock ROM on there forum. Can ROMs be ported based on there code? Or is it more complicated then that?

I have tested LineageOS 16.0 GSI Android 9.0 (and many others ...) and it works well, even GSM and Camera.
The only thing I cannot have is a complete root : I install Magisk 19.3 correctly, but applications cannot get root permission (Titanium Backup cannot have su permission)

If you use the stock boot.img with an GSI system image, it will not boot, you must first flash Magisk.zip before reboot!
It will disable dm-verity, and you can boot after.
If it continue reboot in bootloader mode, use spflashtool to flash a stock rom and all will be right
Or if you have a TWRP backup, restore all partitions except boot/recovery/cache/system/data and you can boot
@ dreambo Can you make a writeup of properly unlocking the bootloader/rooting? Or did you use these methods?

You do not need to unlock you phone, mine is rooted with Magisk and have TWRP installed without unlock bootloader.
Just use spflashtool to flash a stock rom, but replace the recovery by TWRP and the boot.img by magisk_patched.img one.
Here how I do exactly:
1- in my running stock rom, I install MagiskManager and install Magisk by choosing the last option (patch existing boot.img)
2- give it your stock boot.img (extracted from stock rom) and it create for you /sdcard/Download/magisk_patched.img
3- use this to replace your stock boot.img and use also TWRP.img to replace stock recovery.img and flash the whole rom with SPFlashTool
Can you backup with TWRP with a locked bootloader? Isn't write access blocked with a locked bootloader?

I have used the European one, UMIDIGI One Max E V1.0
So I just received my One Max today. I was able to patch the boot image, and root the phone. I also, installed TWRP, but I'm running into an issue. From TWRP, I formatted with a normal wipe, It asked "Do you want to do this, it wipes data encryption Etc". I typed yes, and it did it's thing. Rebooted. Setup my basic settings on the phone. I rebooted back into TWRP, and it immediatly asked for a "decryption" password. It also won't allow me to mount internal partitions or sdcard. This even after I rooted via a patched boot file, and verified root access while booted in android (with root verify app). What am I doing wrong for TWRP to gain access to storage?
"Couldn't wait, ended up formatting with encryption disabled via a zip + magisk"
How did you format without encryption? I try to format from TWRP, type 'yes' , to verify, and encryption is still active. I'd like to disable encryption, so that I can properly backup everything from TWRP.

Search in xda forum a zip that you can flash with TWRP before installing the Magisk zip from TWRP.
its name is disable_dm_verity????.zip, it disable in the boot.img the encryption.
After that format the data partition (format and not wipe, it's important!) and reboot normally, and your data partition will not be encrypted

I eventually found all the correct files to remove encryption. I also installed AOSP. I'm kind of torn between the stock and AOSP. AOSP has better performance, but one annoying aspect is that I cannot find anywhere in the settings to switch the navigation buttons in AOSP (Back button is on the far left, I like it on the right side). Seems trivial, but it's annoying. I can now fully backup & restore in TWRP, which makes life a lot easier.

Do a complete backup of stock from TWRP onto microsd or USB first! System, data, modem, nvram partitions etc. That way you can restore from TWRP, and not lose os, data, or nvram (IMEI).
Specifically, system-arm64-aonly-gapps-su.img.xz
1. Download and extract file you downloaded, onto your phone.
2. Do a format (type yes)
3. Install from TWRP as "image".

Can't install LineageOS

Hi
I have problems to install LineageOS on my new OnePlus6. I tried to install LineageOS with the guide on https://wiki.lineageos.org/devices/enchilada/install. If I follow the guide exactly step by step no OS is starting and I can't boot into recovery because (I think) twrp isn't installed (just black screen with blue led). But also if I first boot twrp with fastboot boot 'twrp.img' and after install the twrp.zip, no OS is starting after sideload or flash the 'lineageos.zip'. I think, the install doesn't finish correct. In the terminal on my debian I can see, that the installprocess ends at 47%. But I'm not really shure if this is the problem and if it is, how I can solve it. Probably in this thread the same problem is described: https://forum.xda-developers.com/oneplus-6/help/lineage-doesnt-boot-black-screen-light-t3958351 Unfortunately no solution is available in the thread.
Now I flashed the stockrom (https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665) and have done all updates but don't know how I can install twrp and after LineageOS. I hope somebody can help me. Thanks
Do you have the latest ADB version? Instead of sideloading you can try just transferring the zip files (with e.g. "adb push lineageos.zip /sdcard/") and then installing directly from TWRP.
Make sure you do all the wipes / formats mentioned in the guide. Transfer and flash the lineageos.zip. Then directly after you should flash the twrp.zip Then reboot back into recovery and flash Magisk / Gapps etc if needed. Then finally reboot to system.
Also read this guide if you haven't already as it explains a lot about how flashing ROMs on OnePlus 6 is different to many other older phones.
Hi and thank you makeyourself
I tried the following steps:
1. starting fastboot
2. fastboot boot twrp-3.3.1-2-enchilada.img -> twrp starting up
3. adb push twrp-installer-3.3.1-2-enchilada.zip /sdcard/ -> transfer ok
4. adb push lineage-16.0-20190922-nightly-enchilada-signed.zip /sdcard/ -> transfer ok
5. in twrp Wipe -> Format Data
6. in twrp Advanced Wipe -> System
7. in twrp install lineage-16.0-20190922-nightly-enchilada-signed.zip
8. in twrp install twrp-installer-3.3.1-2-enchilada.zip
9. reboot to recovery
After this steps I got the same problem as before. Before the reboot to recovery, twrp showed the message "no OS installed". So I think, the zip weren't installed correctly. Now, I have the black screen with the blue led. Can you find out what I did wrong?
Edit: Now, I can't also boot twrp. Also if I do a fastboot boot twrp-3.3.1-2-enchilada.img nothing happens.
Fastboot to twrp (newest blu spark should be fine, or black twrp)
Flash twrp zip
Reboot to twrp
Wipe data, cache.
Flash recommended oos
Flash twrp
Reboot to twrp
Flash recommended twrp (yes...... Again)
Flash twrp (yes... Again, recovery is lost after rom Flash ALWAYS)
Reboot to twrp
Flash LOS or any other custom rom
Flash twrp (rom Flash, so twrp is lost like I said)
Reboot to twrp
Flash magisk (IF ypu want magisk)
Flash gapps (IF ypu want gapps)
Flash kernel (IF I like to run another custom kernel)
Boot
Enjoy
Thank you whizeguy, I'll try this. But just one question about "Flash recommended oos". Which OxygenOS can I flash (this full OTA? https://www.xda-developers.com/oneplus-6-oneplus-6t-oxygenos-9014-906/) and why I have to do this? Sorry if it is a bad question.
You Flash The oxygen OS version that is recommended in Los thread, simple as that.
You have an a/b device, vendor partition (could be other files needed aswell, not 100 % sure) is needed to Flash custom, IF you did Amy research you'd finns some good info. Also for faster answers in The future: post your issue in the thread for LOS, that way you would get help from People Who uses it, knows The exact version you should use and what not
Hey whizeguy, thank you very much. Everything works perfect now. But why for heaven's sake do I have to flash oos and why the guide on the LineageOS site don't tell me this way?
Wow idk what happened here. Mistakenly replied to this thread. Apologies.

Android 10 & Custom ROM & Slot A + B

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?

@Cypher_01, Try this guide. This worked for me. I did not reinstall Nikgapps. Maybe that's where the problem lies? Don't forget to change the update slot at the end before you restart.​
