I want to backup the stock recovery image, how can I do?
I do not have a custom recovery yet
Just download this -- http://www.mediafire.com/?q4jrntqdywu -- it has the stock recovery image in the ZIP.

I remember reading somewhere (dont remember exactly where) that you can make a nandroid backup before rooting or flashing a custom recovery.
This was done by booting into fastboot mode and running the custom recovery, not flashing, just running it. This would preserve the stock recovery as a custom recovery is not flashed, but would still allow you to make a backup of the stock rom without root and without a custom recovery.
Is this a possible method for making a nandroid backup of the stock rom? Which would allow you to return to stock after rooting and installing custom roms?
fastboot boot recovery CWM.img (or whatever you have called the recovery image) will boot into CWM but not flash it and you can then make a nandroid

One more question, even if you have a nandroid of the stock rom, wouldnt your device still show up as tampered and unlocked? Is there a way to remove that AFTER returning to the stock rom..?

Hi, you again
That didn't work for me with CWM, but it didn't work after I flashed it either. It just failed to back anything up.
I didn't try it with TRWP though, in theory you're correct.
After flash this recovery does not run the phone. Always boot into recovery. Can someone to fix it?

What is needed to pull the stock recovery image I already dumped the partition correctly I have root running on stock recovery.
I just need to figure out why i cant boot the stock recovery from fastboot
the screen just gets scrambled. But i mean i do have the recovery.img and boot.img pulled from their respective blocks. and dd'd into imgs
Maybe someone could point me in the right direction and we can have a copy of the stock recovery as well. I don't want to
fastboot flash it in case of bricking the recovery partition(Even though it should be a 1-1 copy)
I wanted to boot TWRP rather then flash it to install super su then boot into system to backup recovery partition using flashify. I can boot into TWRP but then I can't do anything after that.

Hi all.
I have a couple of SM-T813 tablets with Nougat stock firmware.
I want to install Lineage OS on these devices. According to official installation instructions (https://wiki.lineageos.org/devices/gts210vewifi/install) I have to write a custom recovery using heimdal.
I know that with a custom recovery i can backup the rest of partitions before installing Lineage OS, but I want to know if is it posible (and how) to backup stock recovery before overwriting it with custom recovery using heimdail.
How can I backup stock recovery before install custom recovery?
Thank you and regards.

You can pull with adb the recovery partition as .img to your SD card.
Have to know mount point of course.
Good description here:

Perhaps you gotta install adb root as well.
But there is no real need to backup stock recovery as it will be revived automatically, when flashing stock ROM.
Just make sure you have the stock ROM downloaded before you start flashing your recovery (multiple part stock is preferred).
