Does anyone have the official oreo update files? I heard they were available before they got reports of bootloops. And that the bootloops could be fixed by doing a simple factory reset under recovery mode.

Hi,
my P8max is rooted with SuperSU and I had TWRP installed. Now the recent b211 OTA released, and I would like to install it. Since my phone was modified, I won't get an update over EMUI, but I downloaded is elsewhere.
I would love to keep everything setup as it is and avoid the wipe. I flashed back the P8max stock recovery to install the update as local update. Now my question is, will I experience any trouble because I have a rooted phone with SuperSU?
If so, would it be enough to just unroot the phone with the SuperSU settings button "unroot", or is a wipe unavoidable?
Best regards

You have to be on Stock recovery and no root.
if you got an error while installing OTA,
follow this guide to return to full stock unmodified rom http://forum.xda-developers.com/p8max/help/official-rom-download-links-t3206144 then install OTA update.
For those who say that must unroot to see the ota update i say that their rong...i have root and yesterday the ota notification show me that an update is waiting.I will not update because i see that its not stable yet.
Yep, got the notification too, even though I'm rooted and on a custom recovery.

You will get notified, but installing it will fail because recovery checks your system partition if its modified or not.
Did anybody who was rooted successfully updated their firmware with FF?
I tried to update to B156 but it failed. I flashed original boot.img and recovery, tried the 3 available files but no luck. Only the OTA file with 408MB size passes authentication and when in recovery it starts installing but it fails when reaching about 20%.
Bootloader is still unlocked but don't think that's the issue?
Anyone has any idea?

What build number you have exactly?
About root - no way to update while you have root, cause rooting process modifies boot partition. Probably, in some cases you can update, but there is no success stories.
I'm on L29C432B138 at the moment.
I know I could try the offline firmware or a custom ROM (or funky) to get on the latest firmware, but just would like to figure out how we can do this.
I believe that the only options left would be a factory reset and/or eRecovery (or flash my current firmware again but I have no idea how to do it). I'm new to Huawei do not really sure what the use of eRecocery is. Can this be used the flash your current firmware?
FYI: I'm aware of the download current firmware option on the system update page, but for some reason it's not downloading anything.

There were some problems in Huawei with B138 update and 'authetication error' is new for Huawei's users.
Let try this.
1. Backup all your data
2. Return stock boot and recovery (if you did not have it already)
3. Via FF try to install c432b126 Full.
4. Once it started, do factory reset
5. Check updates
6. If no dice, install FF and try to install c432b156 OTA with bigger size.
Note: There are two OTA c432b156
First 471 MB, second 408 Mb
There is probability, that first is OTA from b126 to b156, and second - from b138 to b156
I was rooted with unlocked bootloader on L09C432B138 but couldn't update to B156. I restored stock boot and recovery in fastboot and then downgraded to B126 with FF. Then I updated to B138 and then B156 via system update. Hope this helps

Nice find. Thanks!
Did you lose data in the process? Meaning when downgrading to b126?
Edit: Never mind, found out myself that data couldn't be kept.

How can I revert to the official update? All I tried to get back was a failed message when it reached 5%

You need to extract recovery from the update.app, then flash the firmware using dload method
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.

install a nougat sprint ruu that will restore your phone back to stock including the recovery(you'll loose your data so backup first). then you'll be able to install all ota updates for Nougat.
