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.

Alright..i am going to flash twrp then.Thanks for the help guys.

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.

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.

I have an unlocked bootloader and tried this on my PC:
C:\adb>fastboot boot twrp.img
downloading 'boot.img'...
OKAY [ 0.709s]
booting...
OKAY [ 0.373s]
finished. total time: 1.092s
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.

Any chance you know if you get OTA by now?
I really like the Op3 and dont wont to change anything except i would like to habe root access. Your method seems to be the best way to achieve that.

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

Do the same thing as before? TWRP should work now, so Magisk or supersu should be good to go.

Yes, but you'll have to flash the stock recovery and boot images from your current update (2.38.617.6) prior to taking next OTA or it simply won't update. If anything you or apps do using root to mount system as RW (or modify it), you'll have to flash stock system image prior to taking OTA as well. Best way is to restore stock system image and boot from TWRP backup then find stock recovery on forums or extract from current RUU and flash stock recovery then take OTA.

Easiest way to apply OTAs on Oreo with TWRP?

I am stock rooted. I got an OTA that I'd like to update but it looks like it doesn't want to flash through twrp. I want to stay stock rooted. Do I need to reflash entire image?

Try Flashfire.

If flashfire doesn't work (like in my case), just flash stock recovery and apply OTA. You'll have stock unrooted ROM and you can follow these steps:
1. have stock rom + stock recovery
2. use "fastboot boot twrp.img" (boots TWRP without flashing it)
3. install magisk from TWRP
When OTA cames in, I just apply it and then repeat steps 2 and 3.

Do you know if OTA will work if I have any other system modifications? I pushed some apps to /system for example. :silly:

As far as I know, even mounting system as R/W can prevent OTA update. I wouldn't even try to apply OTA with modified system partition. In your case I would download full factory image, flash everything without data wipe, root as suggested above and apply next OTA without struggles

Have you tried flashfire? I'd recommend it. You can flash the ota, download the full ota from Google, and retain root and a custom recovery. Support chainfire and get the pro version. Although, functionally there is no difference.

Flashfire worked. I had to uninstall SuperSU and reinstall magisk and TWRP but much easier than wiping everything and flashing.

Root without custom recovery?

Is it possible to unlock the bootloader and flash via adb magisk in order to root the phone but still able to mentain the oem recovery so i can flash the updates that are coming more easily?

if u r rooted u cannot flash OTA's, so no u can't

Yes it's possible, however when you install the update you will lose root and have to root it all over again.

I'm new to Oneplus, but Flashfire has worked for me when twrp cannot be installed.

The process will only be to flash magisk via fastboot, right ?

You don't use adb... Patch the boot image with the Magisk Manager and then flash it with fastboot. There are instructions for it in the Magisk release thread.
When updating the OS you'll have to do it again.
In my opinion, the only reason to do it this way is if you've got limited bandwidth and can't download the full OTA zips. Using the full zip is way, way easier... Just download the full OTA file, flash in TWRP and then flash the Magisk zip right after. Done. You don't need a computer at all...
