Lost root and cant boot into twrp after 4.4.4 OTA update

Hi, My htc m8 is bootloader unlocked from htcdev and was rooted at 4.4.3 with stock rom and S-on.Yesterday i got 4.4.4 ota update and after the update,I lost my root which was rooted by supersu.Then i tried to boot into twrp via fastboot by issuing this command:
fastboot boot openrecovery-twrp-2.8.1.0-m8.img
and pc screen says download ok and reboot but phone still stays at fastboot screen and just hangs there.Then i will have to keep pressing the power button to boot it normally. and this method of booting into twrp without actually flashing was working before.Any ideas please.Thanks.

Yeah it stopped working. Flash the custom recovery. When you get the new ota you download it but install it later and extract the recovery.img from the new ota and flash that before installing the new ota.

Thanks for the reply. Actually i have allready saved my ota file before upgrading.Can i do anything without flashing custom recovery?

Well depends on what you want to do. Give root access is only possible with a custom recovery......

Ok. So if i understand correctly, i will flash twrp and will reroot by flashing supersu again. right.
and what would be the benefit of extracting the recovery from ota and flashing as i have already updated to 4.4.4.I would like to get root again and want to remove the traces of twrp so that in future i can get OTA updates like now as i backedup everything by booting into twrp but without flashing it.sorry for the questions as i am kind a newbie. Thanks

You can always return to stock recovery. You're making it harder than it needs to be.

How to go from prerooted to stock rom ?

Hi I m really new to this so excuse me ...
i got many updates by flashing with fastboot prerooted system.img i was on 2.19.40.18 prerooted but i would like to go to a stock no rooted to be able to apply OTA now
I tried an erase of my phone, but i came back to prerooted ...
I tried to install tethered TWRP and to install the.zip from asus download page but it was stuck on updating IFWI .... ( 2.19.40.20 zip file from asus )
What can i do ?
Plz help me

You need to go into the SuperSU settings, scroll to near the bottom and choose "Full unroot."

I did all on this post : http://forum.xda-developers.com/zenfone2/general/guide-to-apply-ota-bootloop-rooted-zf2-t3127835
I did unroot, flashed all 4 line before but i think my recovery is corrupted, it end in error with the green guy instantly and flashin via fastboot recovery.img isnt doing anybetter ...
I m really stuck ..

i was trying an adb sideload with a stock rom is this a good idea ? i got error protocol fault ...

Protocol fault is because you don't use latest ADB. Google it.

i successfully did this but now adb is stuck on serving 13 % and on the phone : verifying update package , it stopped like 15 min ago ...

Here's what I did to go from pre-rooted system back to stock.
1. Download the official latest image from Asus http://www.asus.com/support/Download/39/1/0/13/Lk0Sg1Ulh0Ph49Hl/32/
2. Rename the zip to MOFD_SDUPDATE.zip
3. Unroot via SU
4. Uninstall Xposed and modules if you have them busybox etc. (uninstall.bat for xposed it's easy)
5. Copy MOFD_SDUPDATE.zip to an SD card and insert into phone or copy to internal memory
6. Boot into recovery by holding power and volume up
7. If you get dead android press power button and volume up button and release.
8. Auto installs new image
I went this route after unrooting via SU and uninstalling xposed framework still wouldn't let me run OTA updates for some reason. I imagine I did something along the road or removed a system app or something. It wouldn't let me manually sideload or update and would error out halfway through the process. I cleared fastboot cache and even reset the device to no avail. I was on 2.19.40.18. I installed the 2.19.40.20 image then the OTA update to .22 yesterday.
If I root the device again which is likely I'll use method 3 and the rootkit tool.

i will try your way, installing the 22 now.
But i dont remember in recovery the auto installs new image ?

error in recovery trying to update the .22 like you said, i need to put the .20 before the .22 ?

I installed the 2.19.40.20 full system image (1.1GB) from Asus yesterday. They didn't have the full image for .22 up but they do now. I was on the .18 pre-rooted image. When you hold power and volume up choose recovery and it should install the MOFD_SDUPDATE.zip automatically (mine did). I had issues trying to manually update the phone from .18 to .20 and .22 via ADB (the patches are like 30MB). It would start the update with the android robot then fail about halfway.
Download the correct system image for your device. The new update is available as a full image now so download the .22 image from Asus and then rename it to MOFD_SDUPDATE.zip. Copy it to an SD card and insert it back into your phone. Phone is powered off so hold power and volume up to get the recovery screen. It will say Normal in a big green arrow. Change it to recovery via the volume buttons then hit power button and it should find and automatically install the MOFD_SDUPDATE.zip image.
FYI this is on a ZE551ML 4GB/64GB US WW firmware based phone. I imagine the other models are the same or very similar.
I wish I could articulate this better. Hopefully someone more knowledgeable comes along and lends a hand.

Hi, want to ask.
Previously i root by using Method 1 (PRE-ROOTED SYSTEM.IMG).
can i use your method to revert to stock rom and root again using Method 3 (1 CLICK ROOT TOOL)?

Flashing the entire system image you want to wipe everything anyways in this case. If you mean using the one click rootkit (method 3) to root then no it will not.

Yea. I'm hoping someone finds a way to return this to a "never been rooted" device where the OTA actually works.

Flash the .18 pre-rooted, then don't update SuperSU binary. Take OTAs as needed.
If OTA doesn't show up, download the OTA and adb sideload into stock recovery.

I've done that before, with any OTA, it'll give me the error droid when installing. That's when I said screw it, and try to unroot. And now I'm stuck with that error no matter what.

Is it possible to root the OP3 without a custom recovery?

I don't really need a custom recovery (I don't know of any features custom recovery will give me I really need?) and for now I'm fine running stock roms (I always give stock a few weeks just as a baseline before I start custom roms) but I was wondering, how would one go about rooting the OP3 without installing a custom recovery?
Is it possible / easily doable? Or am I better off just to flash some custom recovery and ditch the stock one?
The reason I don't want to go away from stock just yet is I know oneplus is still updating the rom and custom recoveries, historically, have made OTA updates problematic.

Rooting will also mess up Ota too, but if u install a custom recovery, now that we have stock recovery it will be very easy to revert back for OTAs, there should be a way to root without a custom recovery but I am not sure how though, but with how oneplus makes it so easy to unlock bootloader and flash customers stuff there is really no need to stay stock

You can simply connect your OP3 to a PC and boot to TWRP without flashing it:
fastboot boot twrp.img
Then do a backup with twrp before rooting. I use the above method with systemless root
and also don't really need a custom recovery at this point. This might change once CM13 matures on the OP3...
OTAs might work this way in the future. If they don't, restore your system + boot (kernel) partition
and try the OTA again.
edit: implying your bootloader is already unlocked

As far as I know, you'd have to have TWRP to get root.
I don't think getting it rooted will mess up the OTA updates, other users sprovide flashable zips for the OTA anyway.. so you can still flash the zips manually with TWRP to keep you updated.
Sent from my ONEPLUS A3000 using XDA-Developers mobile app

To get root yes, you would need TWRP to flash to certain partitions but to keep root no. Your phone will operate just fine with root and stock recovery. Check what the user a few posts above mine said about temporary flashing TWRP to achieve your short term goals

So have you actually done this by temporary booting twrp and then using the systemless root and still have stock recovery? Also how do I root systemless? Really wanna know because wanna keep stock recovery and have root

Yes, I have the stock recovery and it is rooted.
The recovery partition has nothing to do with all the other partitions except that it can read and write them.
This is the zip I flashed to get systemless root:
https://www.androidfilehost.com/?fid=24591000424939898
Some users reported that some Root-apps are not supported this way.
I am using Titanium Backup, Adaway, Trimmer and Root Explorer without issues.
Keep in mind that I did not get any OTA so far since running this setup, so I am not sure if official OTAs will or will not work.
All I did was manually flash OxygenOS 3.1.3 in TWRP (not flashed but booted) and reflash the root package afterwards.

C:\adb>fastboot boot twrp.img
downloading 'boot.img'...
OKAY [ 0.709s]
booting...

Nothing happens, bootloader start screen stays frozen. Until I hold down the power button. Might you know why?

i tried to boot into twrp recovery with above command, but the phone seems to be stuck in the bootloader and not responding. Any ideas?
edit: comment above describes exact same behaviour, sorry for double post

Sorry, don't know. Booting takes a couple seconds on my device though.
I am using this recovery img: http://www6.zippyshare.com/v/iK6tCE6D/file.html
Got it from XDA, but unfortunately don't know anymore who build it.

The updater will recognize root on your device and download the full 1.3 gb Rom file.
But after updating root will be gone, so you will have to reflash root after each ota.

Thanks for the quick answer
Just to make sure, if I root using this method nothing will change, except I have root access, my bootloader is unlocked and the updates will be big, but I can update the normal way, I will just lose the root access? Is that correct or am I missing something?

One more thing:
If you have TWRP, automatically installing the big OTA will remove it and go back to the stock recovery.
I always manually move the downloaded ota from android/data/com.oneplus.ota/files/.OnePlusOta
to my download folder, boot into TWRP and flash it + SuperSU on my own.

So you have TWRP installed? I thought you won't get OTAs if you have a custom recovery? So i could just flash TWRP and root and still get OTAs?

Yes, OTAs will come and because of Root you will get the full OTA regardless, which does not cause any issues with TWRP.
I tried my previous method and the regular OTA would fail because of root which changes the kernel or the system partition.
OnePlus reacted to this and introduced the full rom OTAs at some point.
So with root on my device this is how I do OTAs now:
- get the OTA notification for the full rom
- download but don't install
- move the downloaded zip from android/data/com.oneplus.ota/files/.OnePlusOta to my download folder
- manually boot into twrp and flash full rom zip + SuperSU

Yes, you can. You can use tethered TWRP method to root the phone without unlocking the bootloader.
Since you are using TWRP in tethered mode, you do not need to install the TWRP as such you DO NOT need to unlock the bootloader and you still have your stock recovery.
This guide tells you how to root, install xposed and downgrade. Just read the root part and unroot part.
I do not use the twrp mention in that post. Download the latest twrp here.
I did use the BETA-SuperSU-v2.74-2-20160519174328-patch-by-shakalaca-for-zenfone2-6.0.zip mentioned in that post.
The guide mentioned that your bootloader need to be unlocked, however you are using twrp in tethered mode so unlocking the bootloader is unnecessary.
I hope you know how to use the adb.

You can not sideload TWRP. TWRP has to be flashed into recovery partition. Since bootloader is locked, your sideloading TWPR could not be successful as such you still have your stock recovery.
Try to get into recovery.
You might be stuck in the dead robot with red triangle. In that case press and hold the power button, and press and release the volume up button quickly. Try several time until you got into recovery.
If your phone is not booting at all and could not detect from the adb, you might need to flash the .raw file via asus flash tool.
Once your phone is back to normal, follow the guide I mentioned in the previous post to root the phone. You can flash supersu zip in the TWRP install tab.
You can press thank button if my post is helping you.

You can not install the supersu from the stock recovery. Rooting the phone requires to modify the boot.img. From Stock recovery it is not allowed.. As such you need custom recovery like TWRP.
copy the supersu that I mentioned in the previous post to the sd card.
Follow the instructions from the root section of the the guide that I mentioned in the previous post.
That guide tells you to run TWRP in tethered mode.
The command fastboot boot <twrp.img> will move the twrp.img to your phone and let your phone boot into twrp .
Once you are in the twrp, tab the install from zip tab and select the supersu zip file you move to the sd card. If you do not know how to use twrp there are a lot of videos on youtube about twrp.

I am glad that work out for you.
At the end of supersu installation you might see the message saying that you would get that verification error message and tell you to ignore that. I did see that message twice and after that I do not see that message anymore every time I reboot the phone.
I can not help you on the xposed though because I did not install the xposed. I just rooted my phone. If you want you could follow that guide. Load the twrp in the tethered mode and install the xposed from the twrp.

Sorry for rising this 1yo thread.
It seems the tethered TWRP couldn't be successfully flashed on both LP (latest releases) either MM (any release) unless the bootloader is locked. The boot command doesn't give errors, but the phone won't reboot and stay in fastboot/bootloader mode.
Could you confirm that's working on MM, nowadays ?
Thanks

TMO OXC27.1 Oreo firmware

Anyone has the latest(released Feb 16th) oreo OTA full stock firmware from T-Mobile?

I tried pulling it from a logcat. Was going to fastboot flash it since I can't install it while rooted. Every url I found in the logcat gave me a 405 error though.

I got another Moto Z2 Force today. Fresh out of the box TMO. Came with the OCX27. I have not yet taken the update. If someone can guide me on how to extract the OTA That'd be helpful. Only thing I am willing to do so far with this new device is unlock the bootloader that's it. I will not root or install TWRP until I can extract the OTA and attempt to fix my other device stuck in an unknown baseband no IMEI state. I got there by attempting to install TWRP and root with Magisk.

Pulling the log through ADB will yield the OTA download link. That's how @joemossjr and I grabbed the Oreo update from nougat for TMO and Sprint.

It's hard to explain. You have to capture the moment the phone grabs the OTA file from Motorola's update website.
Enable developer options
Enable ADB
Plug phone up to a PC that has updated ADB binaries
Open terminal/command prompt
Adb shell
Logcat
After you do that your terminal of choice will start spitting out the log.
Run the system updater.
Download the OTA. At that moment, one of the logs should give you a VERY long URL. That's the download link you're looking for.
Copy and paste into your browser. You should be auto downloading it.
Done

Very stupid question, but I have to ask, because Moto is a bit wonky on bootloaders and updates, etc.
I'm currently on OCX27 and I've got the notification to download OCX27.1. I do have an unlocked bootloader and I am rooted with Magisk. Since I have not overwritten the recovery partition, can I take this update? On most other phones I have, I've been able to restore the stock recovery partition, flash the update, and flash TWRP back on, but on this Moto, I chose to boot twrp for loading magisk via adb. Make sense? If I'm not able to take this update, can I shut these update notifications off? They are already off in dev options.
Thanks in advance!

I used titanium backup to freeze the update service as it's named in the notification.

Thank you. I looked under U for update. I should have searched... It's actually called Motorola Update Services.

You won't be able to update through OTA if you're rooted

Here's the link to the TMO OCX27.1 OTA firmware if anyone needs it.

Hi, I am wondering, if I am on ocx 27 do you guys think the 27.1 ota will install in adb sideload as it won't install in ota and I am not rooted. Also, is there a way to extract the bin in the ota?

I got another Moto Z2 Force today. Fresh out of the box TMO. Came with the OCX27. I have not yet taken the update. If someone can guide me on how to extract the OTA That'd be helpful. Only thing I am willing to do so far with this new device is unlock the bootloader that's it. I will not root or install TWRP until I can extract the OTA and attempt to fix my other device stuck in an unknown baseband no IMEI state. I got there by attempting to install TWRP and root with Magisk.

Did you get your second Z2 rooted and if so did you use magisk v16? I just got a Z2 today that is on the December 1, 2017 security patch, OCX27.1, Android 8.00 and I'd like to root but hesitant. I have already unlocked the bootloader, placed magisk and twrp-3.2.1-1-nash zip(s) in internal storage, and know how to fastboot boot into recovery, I just don't want to brick my new phone. Any help with step by step instructions once I'm in TWRP to flash magisk is greatly appreciated! Do I need to do any of the following: Keep system read only or allow modifications before flashing magisk? wipe data/factory reset, mount storage, wipe cache and dalvik after flashing? Thanks in advance!

All you need to do is grab the latest twrp img and zip file from twrp. Should be version 3.2.1-1
Then fastboot boot the img file, then once in twrp you want to flash the zip file, then when that is done reboot back into recovery
Then simply flash Magisk and reboot. Done.

How should I properly Flash Stock Firmware?
New to Moto phones and wondering what the correct method is for reverting to stock? I downloaded the 27.1 Oreo zip from this thread, do I flash it in twrp or should I flash it in adb from the bootloader? I get the following error message in twrp whenever I wipe dalvik/cache, try to install a zip, or do a backup which always says fail. I need a fresh install and re root, etc. Thank you!!

you can not flash with twrp. open the zip and see if there is a "flash-all.bat" file as well as adb and fastboot files. if not then pull them from one of the other flashall zips and add them to 27.1 zip. boot your phone to the bootloader, connect usb cable to your device and pc, then run the .bat file.

Factory reset gets the same error message shown in the attached photo. Thanks for the info, unfortunately I'm still a bit confused. Is this the only method to return to stock? I've searched but I'm not finding much and this method is completely new to me. In the past I've used Odin and LG up with my other devices, this is my first motorola. If I wipe internal storage in twrp will that erase the OS and need a new install? I am thinking that may clear up my issues but nervous that the phone won't boot up after that. Thanks and my apologies for my noob questions.

unfortunately other than manually fastbooting each img file to your phone this is the only way. check out this https://forum.xda-developers.com/z2-force/how-to/to-stock-roms-t3672859

Here's the official 27.1 firmware. The flashfile.xml has the correct order and commands to flash in fastboot, or search xda for the converter to a flashall.bat.
