I have a tab 4 8504f currently on 7.1.1
I cannot get it to update via OTA to Oreo because it was rooted at one point. Currently it is not but the system partition is modified so I cannot flash the OTA.
How do I get back to 100% stock so I can take OTAs - or manually flash Oreo?
Figured it out - was able to use this: https://support.lenovo.com/us/en/downloads/ds101291 (Lenovo moto smart assist) to "rescue" my device. By following the instructions it downloaded the 8.1 update and flashed it for me. I am all good now. Easiest way to unroot/restore the system

So my son's 2012 Nexus 7 (32 GB Wi-Fi) is struggling to update. I was checking to see if he got the 5.0 update and noticed he's still on 4.4.2. When I tried to update to 4.4.3 it won't reboot and install the update.
I then tried to sideload the update and it failed due to some certificate issue. Maybe because it's unlocked? I then rooted it again (lost it after the last update apparently) and also installed TWRP. I was going to attempt to sideload from within TWRP but adb doesn't see the device in sideload mode for me for some reason.
Bottom line... Can I just flash the OTA zip file like any other file within TWRP? If not, does anyone have any over ideas of what I can do to update this this without wiping it clean?
I think you will have to flash the 5.0 and images using fastboot. Can you get into ap fastboot mode?
before that though, and to answer your questions:
- unlocked bootloader does not cause issues
- I've used twrp to flash all of the KitKat ota updates directly. simply put the update zip in the internal storage of the device (I always put it in sdcard0/) and flash. the only reason that would fail with KitKat is if you have xposed installed, which was fixed by flashing xposed Disabler zip first. I don't think having root mattered.
- for the lollipop update flashing from twrp didn't work for me. I had to first return 4.4.4 to stock system and recovery (by flashing the system.img and recovery.img files from stock 4.4.4) then adb sideload 5.0 ota update. In your case tho you'd have just updated to 4.4.4 so you can just go straight to sideloading.
All the ota update links are in the second sticky in the general section. make sure you follow the correct to:from build numbers.
I'd prefer this longer route of ota updates, but if nothing works then you can probably just flash system, recovery, and boot directly from the lollipop firmware, and leave userdata untouched. I'd also Not flash the bootloader, as it's reported to have issues.
Hi, I have spent about 3-4 hours looking for a way to get my B29 firmware to Nougat.
The only problem is is that the update won't take because im rooted and have TWRP.
My question is what is the easiest and safest way to get my Axon back to full stock rom and recovery so I can then go ahead and download the OTA Nougat Rom? I love this phone and nougat would be killer
do these files help? which ones in which order do I use? i was thinking the B29 to B15 TWRP but I read that there wasn't one made yet.

I was on B29 (actually I had ZAD v3), Rooted and had TWRP installed.....These are the steps I followed. It takes you back to stock B29 with the stock recovery. Then you can take the OTA.
MAKE SURE you follow the first step in RED... Once you booted to TWRP , Tap Mount and Check "Mount, System as Read-only", this is very important ...I skipped that step and my updates kept failing, once I did that it worked.
I'd also recommend a factory reset once the Nougat update completes, or before setting up completely (using the stock recovery)
Hi, I have a european S8+ fully rooted and with TWRP.
Everything's working great so far but I read somewhere that I won't receive further OTA updates.
Can I install them manually with TWRP?
If yes, 3 questions:
1. Where can I get them?
2. Do I need every single update or are the newest update always containing the older updates as well?
3. Do I lose root or TWRP after installing an update?
I've rooted with Magisk by the way.
Typically if you're rooted and modified the system partition (BusyBox or twrp or whatever) the update will not install in stock recovery. Usually you have to unroot reinstall stock recovery and flash ota. There's toolkits out that can do that. Or you can just find an awesome rom like a rooted debloated rom thats just recently updated and just flash that. Or you can what till somebody snags the ota update location then posts that.
Hi i've actually a S8 on Oreo base band G950FXXU4CRI1 it's rooted with TWRP installed and Magisk. I would like to upgrade to Pie especially for the Dark mode option. I would like to know what is the good process, actually my S8 do not propose any Update from the settings. Do i've to install it from TWRP ?
When rooting the device, you'll lose the OTA auto-update function. You'll need to flash a new ROM on TWRP.
It's pretty straightforward, the procedure us the same as with updating an installed ROM (however in this case it's a good idea to do a full wipe before flashing).
If you want full stock ROM, you can flash it with Odin.
OK thx so i can download my firmware from updato.com flash it after a wipe with TWRP and TWRP will stay on the device i'll just have to redo a root process after Pie upgrade, that's right ? And if i install with odin i'll lose TWRP am i right ?
Hello, I rooted my Galaxi S8 exilon with V-8.0.0./ Android Oreo whit odin v- 3.13 . want to upgrade to 9.0 Pie... someone knows how and where to do it?
So, due to my Pixel's battery life being atrocious I wanted to try LineageOS 14.1 and use my P9 Lite as a daily driver.
I started by downgrading to Marshmallow from Nougat as DC-Unlocker wouldn't work on 7.0 and I needed the bootloader unlock code.
( I used the firmware and tutorial from 4mobiles dot net, looks to be a polish one. )
Once on 6.0 MM I was able to get the code and unlock the bootloader, however, LineageOS and it's TWRP does not seem to work on 6.0 so I needed to upgrade to Nougat again.
Unfortunately, when I try the official update it says there are no updates available and any time I try to use the firmware finder app either the download fails or upon attempting install the phone reports a 'compatibility issue' and won't accept any firmware.
I tried loads of different update.zip files via the recovery update as well as through ADB. Nothing seems to work.
Finally I was able to get TWRP 3.0.2.0 on it, but again, only the version from 4mobiles dot net works. Other versions of TWRP just remove recovery altogether. (I guess they don't work with 6.0)
At this point it's a bit easier to try roms, but still none of 'em seem to work.
-I tried sideloading and manually installing lineageos 14.1 from the sdcard, it fails with ERROR CODE 7
(currently I'm stuck on the 'YOUR PHONE CAN NOT BE TRUSTED/BOOTLOADER UNLOCKED' screen, no splash but I can get into recovery and fastboot)
-Tried flashing boot.img and system.img of various OEM firmwares as well as LineageOS's manually through ADB, same result, bootloops
It seems to me that some other file makes the phone believe that it's incompatible with any of my roms. Maybe the firmware i got for 6.0 is region locked, or perhaps it's the vendor.img that I don't know how to flash?
I know it's a grave mistake but I didn't take a note on what my original version number was. It was the latest 7.0 Nougat EMUI 5.0 update on a UK based unlocked VNS-L21. The 6.0 MM I flashed on it with a rollback update was C900B300.
I tried the proxy method, custom DNS, and manual download on various roms in the Firmware finder app. Even when the download doesn't fail, the system always says the firmware is incompatible when I try to install.
Right now I could put 6.0 MM back on it and make it usable, but I doubt it would be much better than the 7.0 that was on it originally.
Can anyone tell me how I could put the original Nougat firmware back on it? eRecovery doesn't detect any possible updates.
Any help would be appreciated and thanks in advance!

use full update.zip from firmware finder. to upgrade, you can't use latest package. you must use first nougat update.zip.

I've only used Full-OTAs, no bugfixes. None of them seem to work.
Yesterday I tried manually selecting a different model in Firmware Finder;
VNS-L21C185 instead of the default VNS-L21C432-
and downloaded VNS-L21C185B397 update. It verified fine but I couldn't install it due to my recovery being TWRP and not the stock one. What I think I'll try is flashing the recovery of the original Marshmallow firmware that's currently on the system and seeing if it will install this update. I kinda doubt it will tho.
Any other suggestions?
Is there any way I can install a nougat TWRP without my current working firmware being on nougat?
If not, is there any way I can install a nougat firmware with TWRP 3.0.2.0? In order to flash update.zip / update.app files I need to get the stock recovery back, but I can't seem to be able to do that.
Is there any way I can flash a standard OEM Rom onto it with TWRP?

you can't install nougat TWRP in EMUI 4. you can install update.app with original recovery.
extract UPDATE.APP from update.zip
place UPDATE.APP to dload folder in sdcard.
press power button, vol+ and vol-
