I just got a brand new K1. Fresh out of the box with 3-3 pre-installed, I downloaded and used TimmyDean's permanent root tool, flashing a rooted 2-2 firmware. I then enabled the backdoor and ran all the OTA updates up to 14-14. This took several hours in all. I then ran the BusyBox and SU Tools install script. Everything was looking okay. I selected the choice to exit the script with reboot. The K1 turned off and came back on with the Lenovo logo, but, at the top of the screen was red writing:

Unsupported menu option selected: 1
Unrecoverable bootloader error (0x00000002).

It stops there and goes no further. No bootup.

Attempting to research the error, it seems this is not an error too many people encounter or know about, so my guess is that my only way of fixing this problem is to flash the whole thing over again from the beginning. (Unless someone here knows something about this problem. That would be tremendously helpful.)

Having already experienced what it took to go from 2-2 to 14-14 the first time with the permanent root package, I'd certainly like to shortcut it however possible. In this thread, , TimmyDean posted a rooted 13-13 that we can start from. However, the link to the download file for it is, and does not seem to be up for me. Does anyone know where else I can go to try and download a copy?

I'd have posted directly in that Development thread, but, since I am an XDA noob, the forum system only allows me to post in this General section.

After experimenting with the "permanent root" package several times now, each time ending up with the "Unsupported menu option selected: 1" error after any OTA update, I have to believe there is an incompatibility between the K1 I have and the bootloader files in the "permanent root" package. I do not know if my K1 is recently manufactured and they are now doing something different with them that causes this incompatibility or what, but I felt I should warn you all that flashing the "permanent root" package could cause your K1 to not take official updates or to otherwise brick it with the "unsupported menu option" error. Perhaps the 13-13 package, which I don't have and can't test, didn't have this problem.

My serial number is CB1245XXXX. Manufacture date is "11/11/27."

I have now given up on getting root on my K1 and would just be happy to get it back to a working condition that can take Lenovo's OTA updates without bricking. I am currently trying these instructions and will update as to whether or not that resolves the problem: (The forum software will not allow me to post hot links, so copy and paste that to browser.)

The rootzwiki procedure did not work to correct the problem. After any update, the tablet is bricked with the error. There are a few threads on the Lenovo support forum on this issue now, and there is no solution.

I believe these old bootloader files will not work and will brick newer K1's, so my warning is:


This might only apply to more recently manufactured K1's, but, since we do not know when this problem begins, it is not possible to know beforehand whether or not you will brick yours.


Unfortunately, there was no backup option in the rooting packages, so I could not get a copy of the stock bootloader or any other files, if they are indeed of a different and newer variety. If someone has a recently manufactured K1, perhaps you can get those files and share them, because a lot of people are starting to see this problem now.

I have one with sn#1250xxxx, mfg dt 11/11/29. I wasn't even trying to root the thing. I happened during an OTA update. I tried probably all the recovery/rooting option out there. None of them worked. I have the tablet booting at lenovo screen. But I think you are right about the bootloader. If we can get the correct bootloader, we might be able to the the tablet back to life.

Has anyone come out with the fix for your issue.. I have the same issue . Used TImmy Dean's method.. and anything updating past the 02_02 (loaded from the tool I get the error... Anyone here have access to contact JimmyDean to ask him for help?

I see that he updated the tool to K1_A301_13_13_111209_US and maybe K1_A301_14_14_111209_US but all the links are dead.. anyone have a good place to download the files?

those are just OTs.. not image files.. If you don't have a compatable boot loader, you can't load those files.. We don't have a compatable bootloader.. so this is why we need ver 13 of timmy dean..

Can someone who's getting this bootloader error send me a pm. I put together a stock 120109 update that may work around the issue and I need someone to test.
