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.

Hey everyone,
I have a Nexus 5 that I haven't updated in a long time that I'd like to get the latest possible OS for. The only modifications I've made which I think might be important are:
Unlocked bootloader
Rooted using SuperSU (v2.8.2 currently)
Installed XPosed (installer v2.6.1, not sure what version of the framework but it should be the latest supported by 4.4.4) with a few modules
Installed App Ops and removed permissions from some apps
Installed StickMount
I don't believe I have any custom recovery installed (I'd used a script to root and install XPosed originally and I don't know if it made any other changes). I'm comfortable using adb if needed but I'm cool with tools like FlashFire too.
My end goal is to have an updated OS with root and XPosed. I assume I'll need Magisk for XPosed, but not sure about root.
How should I go about doing this? I'm cool with losing all of my data (I'll be making backups with Titanium Backup) though knowing ahead of time if that'll be the case would be nice. If it's possible to update without losing data and without affecting anything that'd be nice, but maybe a clean start would be good? The OTA guide on this forum is only for 5, not 6, and most online guides start with 5. I don't want to mess up obviously. xD
Any advice/steps would be appreciated! Thanks!

You need TWRP. Then to install it. https://forum.xda-developers.com/go...om-android-m-preview-2-flashable-zip-t3157299

The link you gave doesn't have the latest 6.0.1 build and it also says that it requires a minimum bootloader (HHZ12h) that I don't have (I have HHZ11k). Would it be possible to use the latest build from Google? What do I do about the bootloader? And would using TWRP as the recovery prevent me from passing SafetyNet?
Thanks for replying!
Could I follow this guide with the latest factory image and then install Magisk, root, and XPosed? https://android.gadgethacks.com/how...actory-images-android-using-fastboot-0175277/
If you're on stock, update using the built in updates. That'll get you all the latest firmware. I'm pretty sure the N5 goes up to 5.0 normally.

Would I have to do anything to XPosed or supersu first? I'd like to update to 6.0.1, too. I've seen online that there are OTA updates for it too.
Nope. But you may have to reinstall root, which is very easy once you're updated. Just let the updates do their thing, and you'll be on your merry way! Hope I helped
I think what I'll do is flash stock 4.4.4 keeping user data and then use the OTAs to update to 6. That way I have a clean system install to use Magisk with without losing any user data. (If that doesn't work I'll just flash 6.0.1 for a clean install.)
I have a rooted phone with a rom that isn't being supported anymore but it actually works great. I just want to update to oreo so is there a rom I can flash from twrp that is already rooted and ready to go? I saw a video of a how to install oreo 8.1 but it's just music playing with someone showing the menu option and no installation instructions.
The OpenKirin ROMs don't work with TWRP. Moreover, TWRP is risky -- it is much easier to recover a phone using the stock EMUI recovery than with TWRP. It is probably better to eliminate TWRP (which will not eliminate your rooting) by flashing the stock ramdisk), then use Magisk if you want to take advantage of root for installation of unapproved apps. I'm not an expert -- this is what I get from reading threads. Now that I'm running OpenKirin (Carbon), I haven't bothered to install Magisk again as I don't need it, but I appreciate that there are things you can do with it.

Last night I installed Oreo from a custom nougat rom. My wifi tether was working before now it isn't so I'll have to figure that out and maybe re root etc.. Is OpenKirin Oreo?
Yes, OpenKirin is Oreo 8.1.0, with security patches in Carbon 3.1 of July 2018. (The OpenKirin site currently has Carbon 2, which has the June patch, but you can get 3.1 from the telegram support group, which is what I'm running. It will show up on the OpenKirin site sooner or later.)
Can I go from stock 8.0 to OpenKirin? Since it doesn't use twrp I'll have to read how to do it.
Edit: Where do I find OpenKirin Carbon? I didn't see it in the rom section here.

There are instructions at the site as well as downloads. The current version of Carbon, 3.1, can currently only be reached by going to the telegram group, but I found no bugs in v2.
Yesterday XIAOMI Mi5 has get a new update.
About TWRP aborts the update, because firmware MIUI 8.8.30 is required as a minimum requirement.
However, I find these not to download - does anyone have a link?
Regards & Thanks
Same here, does anyone can provide the download link ? Thank you
same here and the last update that worked has some bugs.
Apps crashing, battery drains etc.
Was hoping the new update would have fixed these issues but alas
I cannot get TWRP to flash giving the same error about MIUI 8.8.30

This is to all of you, you can't apply stock OTA updates on rooted devices or devices that have TWRP installed. Stock OTA updates require an unmodified system partition(meaning no root, no Xposed, no root mods of any kind).
OTA updates also require stock recovery, not TWRP.
You can all try flashing any stock firmware for your device then wait for the update notification then try the update process.
To those of you that have TWRP installed, this is a good example of why it is so important to create a nandroid backup of your stock ROM before you modify anything on the device. If you had that nandroid backup, you could restore the backup, then flash a copy of your stock recovery, then unroot the device, then wait for the update notification, then you'd be able to apply the current update. Then after applying the update, root the device again and flash TWRP again, then create a new nandroid backup of the updated stock ROM and delete the older backup from before the update.

I am running Lineage OS 15.1 when it applies the nightly update I get this error.
So what you are saying is they updated to MIUI 10 which as what I can see updates to MIUI 8.8.30 which includes new code
that TWRP and Lineage cannot install over. Also there is this Xiaomi's anti rollback that is installed as well so I am guessing
either live with the last Lineage OS update or install stock MIUI and call it day.

Oh, you mean a nightly update of LOS?
Maybe the MIUI update contained a bootloader update and the new builds of LOS were built to work with the new bootloader?

Interesting I encountered the same problem. Lineage Cannont update because 8.8.30 stock ROM Miui is required.
Simply download latest available miui firmware. Via TWRP install it and then immediately install latest LineageOS.
Here is the link to the new MIUI

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.
Hello all,
My phone came with ColorOS OOS 12 and I hate it. As soon as I rooted it it started crashing daily, I even reflashed a fresh oos12 image using the local update tool and only granted superuser to one app (solid explorer so I could access user files) and it still crashes. Not to mention all the apps i want to use don't work on android 12 (call recorder, busy box) and no custom recovery.
I've been reading through the forum and I found a downgrade package that looks like its hosted by oneplus: https://oxygenos.oneplus.net/OnePlu...all_2107082125_downgrade_059624cc7298428b.zip
I just wanted to make sure I am doing this correctly...
Do I use the OP Local Update app to flash?
Will I be able to flash TWRP for android 11 afterwards?
Will i need to relock the bootloader?
Should i re-root using the magisk slot b method or wait until its flashed and use TWRP?
Will it try to OTA back to android 12? If so, what's the best method to get on the latest version of android 11?
Thanks for the help.
I am running COS C.62 on my OP9 with root and having no issues. Did you make sure to do all the things in this guide?
Root OnePlus ColorOS 12 OxygenOS Android 12 via Magisk
In this tutorial, we will show you detailed steps to root your OnePlus device running ColorOS 12 Android 12 via Magisk Patched Boot.img file.
www.droidwin.com
Anyway, yes, use the local upgrade APK, put the downgrade file in the root of storage, run it. Reboot. Factory reset and wipe data to clear out any leftover crap (don't restore a backup - if you want to use Clone Phone you can do that but only restore app APKs and messages). When it reboots it should offer the latest OOS11 OTA first. If not, just download it and place it in the root and use the local upgrade function in the settings menu of the OOS11 system updater.
There is no need re-lock the bootloader and if you do, you risk a brick that has to be recovered with MSM Tool.
Root by following the guide I linked. I just went through this yesterday after flashing COS broke mobile data. I have Magisk 24.3 working with denylist, Widevine L1, and SafetyNet passes so I have Google Pay.

Thank you, ill give it a try.
First i used the payload.bin method and it was crashing, then i reflashed the latest OTA using the local update tool and used the magisk slot b method. still crashing.
It might have less to do with the root and more with me using root to disable certain apps (youtube, chrome, OP community, google news/podcast/tv) i dont want them on my phone but they might be too tightly integrated. If its still crashing on android 11 ill re-enable them and see if that helps.

Okay you're on OOS, not COS. COS doesn't have Google apps by default (but has plenty more bloatware, I just don't use it).
It's certainly possible that disabling Google apps is your problem. If you don't want Google apps, you're better off with a custom ROM that doesn't have them. CalyxOS has a beta for OnePlus 9 and it's totally de-Googled. There's also Lineage.

ahhhh. i didnt realize there was a difference. I thought OP was just calling their android 12 build ColorOS.
Either way, for custom roms i would have to go back to 11 to flash TWRP right? or can you flash custom roms using fastboot?

You would need to back to 11 because OnePlus hasn't released working sources for 12. Just use the downgrade package, factory reset, then upgrade to 11.2.10.10 and you'll be good to go for custom ROMs. TWRP isn't used for flashing them, they all generally post their own recovery. StagOS was the best one I used (plus the dev is really responsive when there are issues) and people seem to really be enjoying Nameless but that came out after I went back to stock so I haven't tried it yet.
Before you mess with custom ROMs, make sure that you download the global MSM Tool and make sure you can connect it. Honestly since you have to go back anyway, might as well download and use the MSM Tool to get the device back to 11 anyway.

Frist off Im not responsible for anything that happens to your phone!!! VERY SIMPLE IF YOU ARE BICKED,BOOTLOOPED OR JUST WANT TO GO BACK TO 100% STOCK THIS WILL WIPE ALL DATA!!! AN RELOCK BOOTLOADER OOS 11.2.4.4.LE25AA MUST HAVE QAULCOMM...
forum.xda-developers.com
Easiest way to get it into EDL is adb reboot edl but if you want to practice the key combination in case you can't get into the OS, I found if you open the MSM, check use lite firehose, and click Start before you connect the phone, it has less connection errors because it's waiting for the phone so as soon as you connect the cable, it pops up.

Yeah TWRP has issues. I soft bricked last time I tried to do anything with it and had to use MSM Tool to get back to working order.
