[Q] Will OTA from Sense 4.3 to 4.4 unroot and wipe my custom recovery?

Hello,
I have a Developer Edition (unlocked) with Stock 4.3 at the moment, is rooted and with TWRP 2.6.3.0 custom recovery, my phone is asking me to upgrade to 4.4. My questions are:
- What would be the results of the upgrade?
- It will flash over my custom recovery without problems?
I guess I will loose root and custom recovery but I can flash them again, my main concern is that the OTA will not flash correctly for being rooted and with custom recovery. Thanks a lot for those that know the answer and want to help me.

Actually, you won't be able to do an OTA update when you've a custom recovery (you shouldn't even get it in the first place, sometimes it comes through), if you try to apply the OTA, you'll boot back to the TWRP recovery.
So, you should either go full stock (recovery & ROM), then do an OTA. Or flash some 4.4 Custom ROM.

By itself the phone alerted me that the OTA download is available and wants to download and flash itself as it did when it upgraded from 4.2.2 to 4.3 so I am not planning to flash through TWRP...

it will download OK, but when it reboots to start installing, you'll just see the TWRP screen and nothing is gonna happen; because the OTA expects stock recovery.

Thanks!!!!
I guess I better flash another 4.3 or 4.4 by myself, I just thought the OTA would be better first to upgrade to the latest firmware...

you can do two things:
1- get s-off and flash any firmware you want
2- "download & install later" the OTA, once downloaded pull it to your PC, the OTA file will contain a "firmware.zip" which is signed and can be flashed in fastboot ruu mode (you have to issue the flash command twice!!!), which would upgrade your firmware (including hboot, kernal and recovery), but will leave your rom intact
----- because it flashes recovery, you need to reflash custom recovery
----- and, kernel (boot.img) you'll need to reflash the custom one (or dirty install the ROM), otherwise the ROM won't boot up

I've looked around for a CWM compatible version of the Dev Edition + Root, but I'm not finding one. Is anyone aware of a CWM-packaged version that I can flash using CWM on a rooted device? Reverting to stock to pick up the OTA seems like a long way to go

[SOLVED] SuperSU and Re-root on 4.4.2

Hey everyone
I've recently solved my OTA problem (seen here) but I soon discovered yet another problem.
When I tried to enter SuperSU, I received the following error shown below.
As mentioned before, I'm on 4.4.2 and I have NO desire whatsoever to unlock my bootloader all over again. Is there anyway to re-root my phone without unlocking my bootloader or will I need to do just that in order to re-root?
Thanks in advance

Anyone?

Please help :crying:

From what I know, and by the error displayed on the attached screenshot, you need to do the whole rutine all over again. I am pretty sure rooting can not be done if bootloader is locked, which might mean you have a stock recovery image as well - and since that is not keen to be rooted (as far as I know) you need to flash a custom recovery like twrp. I might be wrong in all this, I'm newish to all this.

Since you are S-ON you can not flash a custom recovery or root without unlocking your bootloader.

Well, for starters, my bootloader is unlocked (as mentioned before), thus we eliminate the bootloader unlocking dilemma. But it still doesn't tell me how can I re-root my device: you want to tell me that I have to do is to flash a custom recovery and install SuperSU again, and my phone will be rooted again?

yes you can flash your stock recovery again, might be a good idea to do a nandroid backup of your current config before flashing back the stock recovery.
Code:
fastboot flash recovery name_of_recovery.img
fastboot erase cache
fastboot reboot

An OTA update will not work on a rooted phone! For the OTA to work it needs stock recovery, stock rom and all of the files that it is attempting to update. If anything is missing then it will error out and return to your present setup.

and to complete what majmoz already said, if your rom is 100% stock, and you have flashed back your stock recovery, the phone will update fine but you will loose root. You'll need to flash a custom recovery after the OTA to re-root the rom.

Guys you're very helpful and i must thank you for that. i am on the official 4.4.3 rom so i just need to restore the stock recovery? how to do that? and will the current rooting method work on lollipop (and should i follow the same steps to install clockwork recovery)? Will the ota update relock the bootloader?
i'm sorry if i'm asking too many questions but i don't trust any other forum.

If you have not modified anything to your rom (Kernel is stock and always was, you have not deleted any /system files and you still have or restored all the content in /data/preload (wiped during bootloader unlock), so yes all you need to do is to flash back the stock recovery that match your version.
how to do that?

The same way you did to flash a custom recovery:

You always flash the recovery using the same commands, stock or custom, on all versions its always:
Code:
fastboot flash recovery name_of_file.img
fastboot erase cache
fastboot reboot
Will the ota update relock the bootloader?

OTA updates will never affect the bootloader status (S-ON/S-OFF, LOCKED/UNLOCKED/RELOCKED)

If you have not modified anything to your rom (Kernel is stock and always was, you have not deleted any /system files and you still have or restored all the content in /data/preload (wiped during bootloader unlock), so yes all you need to do is to flash back the stock recovery that match your version.

So, if I did flash a custom kernel, and did uninstall system programs (but didn't flash a custom Rom), what are my options if I'd like to upgrade to lollipop?

did you check out Sdbags thread? All the instructions you need are there:
http://forum.xda-developers.com/transformer-tf701/development/rom-t2839030

did anyone get a security update on their m7 this morning?

I got an OTA update named OTA_M7_UL_L50_SENSE60_MR_TMOUS_7.18.531.35-7.18.531.2_release_450302.zip with size about 180MB.
Did anybody else get it?
I can't apply the update though because I have twrp and the phone is rooted. I was wondering if someone else got the update and applied it successfully on a rooted phone.

Should post this question here: http://forum.xda-developers.com/showthread.php?t=2305490
and the answer is probably yes since I don't see why T-mobile USA would push an ota update only to you
7.18.531.35 is the t-mobile US equivalent of 7.17.1540.35 which is the latest version with the stagefright 1.0 vulnerability fixed.

You need to be on 100% stock rom including stock recovery to install ota updates. Better to return to stock using a ruu before applying the update imo since many users soft bricked their phones when attempting to install lollipop ota updates on stock rooted phones. If you need the RUU, look in the RUU collection thread, there is a 7.18.531.2 RUU posted there (link in my signature). Don't forget that questions should be posted in the q&a section, not in general. :good:

Thanks for your help. I found the RUU for my version. So, since I need to go back to RUU flash, I will need to re-setup my phone from scratch again just for getting this OTA....sucks!!
I wish they would make it easier to update modified phones. Just overwrite my root changes to /system and destroy my recovery but keep my /data and /sdcard. I can recover from that much faster than doing RUU and set up from scratch!!
So, on m7, isn't there way to flash stock on /system and stock recovery through fastboot and then take the OTA? I have done that on at least Samsung and Moto phones in the past and it worked fine.

So, if I restore system and boot partitions from my backup to stock, can I sideload the OTA ZIP using TWRP?
I should have made a recovery.img from the original stock recovery partition. Do you know if I can find the stock recovery here somewhere?

It is, you'll loose root every time you do an ota update.

The ota is flashed using the stock recovery, and the stock recovery is also updated in that process.

Yes, either using a RUU, or a combination of a stock rom/backup (/system partition) flashed using twrp and then flashing the stock recovery back.

No, the updater-script will only work with stock recovery

You can't backup the stock recovery directly from the phone (actually yes you can but it requires s-off and its somewhat complicated.

already uploaded here:
https://www.androidfilehost.com/?fid=23991606952604831
or you can extract it from the ota update.
It was possible to update a stock rom + rooted phone simply by flashing the stock recovery back in the past (on kitkat roms and eariler) but it looks like its not possible anymore on lollipop updates. So much ppl posted here with the same problem: "Phone is stuck at HTC splash screen after installing update on stock rooted phone". Example here and here
The biggest problem if the ota install fine but the phone is stuck at the booting screen (like in the link above) is that your firmware will be updated to 7.18.531.35 so you won't be able to use the 7.18.531.2 RUU anymore unless you achieve S-OFF or edit your MISC partition.

Thanks for the great help! I can't thank you enough.
One question: if I do fail to apply the OTA zip after restoring boot, system and recovery to stock, I will still be able to get TWRP back on the recovery through fastboot and restore my full TWRP backup to get a working system back, right? Is there a gotcha in that route?
