installing Android 10 over Pie - Google Pixel 2 Questions & Answers

I'm wondering if I can install Android 10/Q over Pie without having to clean flash. On the Pixel 3 there were issues during rooting when there wasn't a clean update.

I'd say try it out. I just installed Android 10 yesterday via ADB sideload over Android Pie with TWRP. As always, perform a backup in TWRP before going forward with anything.
Edit: to clarify as well, I was rooted with Magisk and TWRP on Android Pie. Using TWRP/adb sideload, the OS updated without any issues. After that, I installed TWRP and Magisk v. 20.1 again and have been fine for 16 hours.

Downgrading from Official 9.0 to 8.1

Unlocked bootloader, VZW pixel 2 here.
I upgraded to official Android 9.0 Pie, but realized it's hard to live without Xposed, so I'm looking to downgrade back to Oreo.
The guides I found described flashing the Oreo image, but it won't boot. Is it possible to downgrade from Official Pie to Oreo on the Pixel 2?
As I understand it, you can downgrade an official build. You could potentially flash a custom 8.1 room tho.
A clean install worked to downgrade to 8.1.
Unfortunately, adb backup wasn't successful for me and Play Store didn't download any of my personal apps upon logging into the fresh install...

Same here. Tried pie but not as good as having gravity box. Maybe a custom rom with all the tweaks will come out before xposed is supported.

Oneplus 7 Pro OxygenOS 10.0.1GM21AA TWRP 0MB can't mount data

Hello,
today I got the official Android Q Update for my Oneplus 7 Pro.
Since my phone was rooted, I downloaded the whole update, let it install and didn't reboot.
Then I installed Magisk over the Magisk app to the other partition.
After that I flashed TWRP as module via Magisk and flashed Magisk.zip again via Magisk.
Then I rebooted my phone and it was rooted as expected. The problem is, my TWRP has no access to my sdcard.
A week ago I installed already the OxygenOS 10.0.0 for testing purposes and had the same problem. I didn't focused on the TWRP problem because I went back the same day to OxygenOS 9. Since I have now the official OxygenOS 10 I would prefer a working TWRP.
Any possibilities to get TWRP working or do we have to wait until TWRP rolls out an update?
I read severel posts of people who got TWRP running but these are from the Beta and I am not shure if running only means that TWRP is on the phone even if it can't acces the sdcard.
Thank you very much.
The unofficial twrp 70 works well for me. Just search in the forum.

Thank you for your reply. I tried the TWRP 70 but I still can't mount the storage...

TWRP on Android 10

After recently bricking my Oneplus 6 by trying to flash the latest TWRP on the latest Android 10 OTA from Oxygen Updater, I found a post from official TWRP explaining how root with a10 will take a while to implement due to changes that Google has made to their partitions.
So I guess for anyone trying this out on their own, be warned. You will probably end up bricking your device like I did and will probably end up having a bad time.
Please correct me if i'm wrong though, peace!
Edit: can confirm fastboot flash boot twrp-3.3.1-11-enchilada-Q-mauronofrio.img from the other popular post is working!
If you already have a working TWRP on OOS 9 you should be fine as long as you flash a working TWRP afterwards. Blu_spark TWRP 9.101 is compatible (please not 9.101 no earlier version will work).
Also don't use Magisk 20 only 20.1.
There is already a pre-patched version out there. You can fastboot flash it (as fastboot boot doesn't work). An easier way (without a pre-patched version) is currently being worked one as you pointed out already
just updated to a10
boot into twrp, flash new bluspark twrp
flash FULL ota a10 image
reflash twrp

Which build did u use mate? R108 is not working with android 9, I tried flashing it using my older installed twrp.
It says unsupported android version. And in github r108 says only for android 10.
r108 is the kernel not twrp

I can confirm that this is working for me. I successfully upgraded from Android 9, Oxygen OS 9.0.9 to Android 10, Oxygen OS 10. Steps that I followed :
1) Flashed new twrp from link in the above post by akri1337 using my previously installed twrp : bluspark 9.85.
2) Flashed Oxygen OS 10 full update and added to queue latest bluspark twrp which I flashed in step one as it would be overwritten by flashing the full OTA update.
3) Rebooted into recovery again to switch to active slot.
4) Flashed Magisk 20.2 to regain root.
This process successfully upgraded my Oneplus 6 without any data loss.
Please note that I disabled all magisk modules just to be safe before starting the upgrade process but didn't uninstall magisk. I was on Magisk 20.2 earlier.
Hope this helps everyone.

Which magisk? Ver 20.1 ?
Why is it that I get an error when trying to flash the full OTA update using TWRP? Something about error 7 and not have a digest file. Is there a full OTA update file that everyone is using? I tried the signed full zip from here on XDA and the one from Oxygen Updater. I get the same error with both.

Still confused as to how everyone else can flash these zip files through TWRP and I cannot.
I'm currently Magisk rooted and have TWRP installed. Will I lose root and TWRP when updating through the local upgrade method?

Yes, you will need to flash twrp with adb and going through the hole process of installing twrp and magisk, but for me its not worked well, after first boot to Android Q with magisk 20.1 and granting some apps root access when I rebooted the phone its not booting to system and going to bootloader, I think its related to some problem with magisk 20.1.

From OOS 10.0.1 trying to install LOS 16.0 as a beginner and failing completely

I'm trying to install LOS 16.0 but it just won't work. I've tried using the TWRP 3.3.1-16 Q Unofficial by mauronofrio and it works that I can get into TWRP and can flash the rom and GApps, but then after that process once I try to boot into the OS it is just forever stuck in either fastboot or stuck on the bootloader unlocked warning screen. I did realize that I had to use fastboot flash boot twrp*.img because they disabled fastboot boot twrp*.img in the Android 10 update, but then am I supposed to reflash something on that boot partition now? The whole process is very confusing and the instructions from the LineageOS seem to not work at all. Is there anything I can do right now or is it just not possible to install this until TWRP, or OOS, or something I'm not knowledgeable enough to know about updates?
It's because you are using OOS 10.1 as a base (android 10) and you are trying to install Lineage OS 16 (android 9), so it's quite obvious why it isn't working. Try lineage OS 17 instead.

Lineage OS 17 won't work either. The developer intentionally used OOS 9 as base since fastboot boot command doesn't work yet on OOS 10. OP needs to downgrade to OOS 9 first, whichever of the two Lineage OS versions they wish to use.

I tried this. I downgraded to 9.0.9 and still the fastboot boot command is not working. Apparently this has something to do with the bootloader image itself not being downgraded?
I give up now, my temp phone I was using for holding backups for chat data just randomly wiped itself on havocOS and I've just lost years of chats and stuff and it's got me really down right now. They did fix the fastboot boot issue with today's 10.3.0 update but still nothing is working from any tutorial to get this thing to work on lineage, it just won't boot to it and twrp keeps having errors during flashing. This used to be so much easier on my older phones and I've installed this OS on about 5 phones now but OnePlus 6 just doesn't seem to work no matter what. I'm just going to go back to OOS and hope LineageOS 17.0 will get these issues ironed out by the time it releases. Severely disappointing and a waste of 3 days now but oh well
In my opinion, this is the easiest way to downgrade everything to OOS 9, including bootloader https://forum.xda-developers.com/oneplus-6/how-to/op6-collection-unbrick-tools-t3914109
After that, just unlock the bootloader again like usual and follow the LOS16/17 page's install instructions and you should be good to go.
I tried to install Havoc 3.5 while i was on 10 Ob2, unlocked bootloader and installed patched twrp, then rom. Got stuck in fastboot mode. **** hell i messed everything, later i found fastboot recovery rom from xda, flashed it, thank god it saved me. For me, msm tool was not getting connected, got an error like sahara xyz something... Then after refering to multiple xda threads came to know that most of the present 10 custom roms are based on oos android 9. Then again i used downgrade package from community, reverted back to ob 25 oos (pie), then as usual installation process. So if you are interested in custom roms, downgrade to pie. And again i wanted to go back to complete stock from havoc but unfortunately msm was not responding and fastboot roms wont support upgradation (im not sure), i went to twrp and installed stable 9.0.9 to both partitions + twrp installer. Then 10 oos stable to both partitions + twrp. Then booted up and installed Ob2 again from system updater, lost twrp on that process, then locked bootloader, so mow completely stock ? lot of work for nothing ? oos is better for me.. infact i got used to that. maybe i should purchase another phone to continue the momentum of getting latest updates. crazy oos influence ?

Been gone for a while, help confirming a few things to upgrade to Android 10

Hi, hoping a kind soul out there will help to confirm a few things about moving to Android 10 from Android 9
I haven't bothered keeping my phone up to date for around a year, and I'm just looking into updating to stock OOS 10 for now.
I'm currently rooted with TWRP & Magisk running an old Android 9 custom ROM, and there seems to be a bit of confusion around TWRP and updating to android 10. I'm looking to completely format the phone, not worried about loss of data as I'll just restore titanium backups, so my plan is this to get a clean install with TWRP + Magisk+Gapps:
1) Reboot to current bluspark TWRP, Flash OOS 10.3.0, Flash twrp-3.3.1-16 mauronofrio installer.zip, Reboot to recovery
2) Flash OOS 10.3.0, Flash twrp-3.3.1-16 mauronofrio installer, flash Magisk 20.3, flash GApps arm64 10.0 nano, reboot to system & enjoy.
This was always my normal update process so i'm pretty comfortable with this way if it will work.
Can anyone confirm if this will cause issues due to TWRP not working properly with android 10 when i preform my first reboot to recovery? My thinking is that if I flash it after installing android 10 then any issues caused by android 10 should be fixed, is this correct?
Thanks!
There is no confusion at all.
Everything is clear since months ago that 10.3 was released.
Upgrade firstly to the latest 9.x Rom, then flash the latest TWRP and then u are ready for flashing 10.3 and latest magisk.

ok, so I have to go to OOS 9.09 with twrp-3.3.1-16-enchilada-Pie-mauronofrio, before upgrading to 10..3.0 & twrp-3.3.1-16-enchilada-Q-mauronofrio, even if I want to just do a full wipe and start fresh on 10.3.0?

The rest has already been discussed.
