[TF300] After installation JB 4.1 the recovery is broken and cannot root

[aleXka]

Hi all,
Previously I used 4.0 HYDRO.
Last time I upgraded my TF300 to official JB 4.1. But the official one is really brake!
I want to install HYDRO 4.1 but here is the problem.
After installation of official JB 4.1 my twrp recovery is overwritten by another recovery and this new recovery doesn't work.
When I try to boot into recovery I get an image of dead Android robot.
So I cannot boot into recovery and I cannot rrot my tablet to install another recovery tool.
How can I solve my situation?

Welcome to the forum, aleXka.

I'm moving this to development, you'll likely get more looks there.

I don't really know how to fully answer this question, but I believe I may be able to point you in the right direction.

For root on JB I assume what you have to do is downgrade to ICS, root, use rootkeeper backup, flash jb, then run rootkeeper so you will have the root in JB I'm not sure on this though... I think a new way of doing it has been discovered, though I won't link to outside sources on this one, as I don't have permission to distrobute nor provide the instructions.

Hi,
Thank you for the answer but how can i downgrade it if my recovery is dead?

I installed twrp recovery by the command
fastboot -i 0x0b05 flash recovery twrp.blob
Now I can boot into recovery!
