when i unlocked my xt1550, i made a twrp backup of unmodified stock rom. and today i restored it. i got 59mb update but it always fails (yes, i restored stock recovery.) any idea what should i do other than reflashing stock firmware?
You need to flash the latest stock firmware available for your device. That's the only solution in your case.

I am selling my 300T and I have downloaded the latest JB .20 ROM from Asus. I am currently on JB .18. I want to return everything to stock before I sell it. I am currently rooted with an unlocked bootloader and have deleted some stock apps. I have TWRP recovery currently installed. Will flashing via Fastboot be the best method? Will this flash the recovery as well? I saw another thread saying that flashing the blob file via fastboot restored the tablet to stock completely, but there was a discrepancy on the command to use. Thanks for the help.
Refer to the link below, it's a thread I just posted in concering the same issue

As we All know we are going to get Android 5.0 Lollipop OTA in coming days and for OTA stock recovery is necessary.
Downloading whole firmware just for stock recovery is not worthy that's why I'm sharing stock recovery of Asian variant(XT1033 including India).

Stock recovery(Here)

Waiting so anxiously for Lollipop
BUT, flashing the ENTIRE firmware to OTA your device is a MUST.
OTA will fail if your device was rooted then unrooted because system partition was modified by root.. So, for the update to succesfully work, you have to flash entire firmware (including stock recovery), like it or not, to have an untouched system partition.
Flashing only stock recovery again is not enough, it will make no difference, OTA will fail.
So, this thread is kinda useless if you think about it...

Flashing Stock recovery alone wont work... I tried flashing the stock recovery alone for upgrading to 4.4.4.. but it didn't work..... We need to flash the whole firmware again for successful upgrade..
But it's good if somebody else want to find official recovery

Hello,
I have the Xt1562 Indian version running 5.1.1 - which I have rooted and also have TWRP as recovery.
The OTA upgrade gets downloaded but fails. I then reverted to stock recovery but still the OTA upgrade fails.
How can I upgrade to Marshmallow on this without losing my data or apps or contacts?
Thanks,
Padam
Ota fails since you're rooted. You can try TWRP flashable MM rom and dirty flash it without wiping /data
Ota is possible only if you are in stock firmware and stock recovery. Fast boot flash stock firmware and get ota or directly flash updated firmware. Githup has all stock firmware files.
Never use stock update via TWRP , you may brick your device.
During giving fast boot commands , skip fast boot erase user data will not wipe data , but while doing this I have some FC s. Otherwise backup all your files , apps data and flash firmware.
Hi,
I used this tutorial to restore stock version from Cyanogenmod mod.
In this tutorial it's said "You will be unrooted after this procedure" - it is still unrooted, but room is new!?

Is there anything else I should downgrade / upgrade so I get original version. Right now I still see that my device is rooted. Also I still have some problems when I boot my device like before.?
Try manually flashing each partition, including userdata.img file, and factory wrote before booting the ROM for the first time.
After a proper flash, root should be gone.
Just do flash-all using a factory image from Google.
Hi there !
I have U11 2.31.400 version
-Bootloader Unlocked
-TWRP installed
- Root with Masgik
Now i want get OTA update
-First, NO RUU, i tried Restore NANDoid backup and Flash stock recovery (same version)
(https://docs.google.com/spreadsheets/d/15JL3tRWDSVOUKo_revEYtQ_tRcOSJ0vWcvk8a7TK8Hk/edit#gid=1564536856)
-> Not work
-I tried flash stock Firmware ( got 35_RU_Partition_not_support firmware error)
Anyone can tell me how to got OTA with out RUU??
Hi there
I think we're in the same situation.
I also unlocked my phone, installed TWRP and Magisk on stock system and did a NANDroid Backup before doing so.
In order to get the OTA I restored stock recovery (which i had to extract from OTA, since i forgot to back it up) and started OTA.
--> Red Triangle!
Even after restoring stock NANDroid the OTA wouldn't install.
My mistake i think was that i didn't kept the stock system read only when i did the backup in twrp and swiped to allow modifications.
According to some threads here, even mounting the system r/w would break OTA functionality.
So since i also have no RUU for my device, i don't have the chance either to go back to stock. Maybe you did that mistake too.
The only way i can think of now, is to go temporary S-OFF, change CID and MID (to 401 international for example), flash Firmware and run the RUU for it.
But i'm not sure it'll still work after flashing the firmware.
Can anyone maybe confirm this way would work?
Thanks
Edit: Hi, in case you're still having this problem, here's a solution:
Reverting to stock
