Padfone 2 Invalid Kernel !!!

4 posts in this topic


Hi everyone I have a asus padfone 2 stuck on logo with Invalid kernel message on top of the screen!!!

My phone was rooted with FRAMAROOT.APK with nothing to do with the bootloader unlock app cause is was not working, maybe because of the new august update of jelly bean...

So my biggest mistake was trying to install TWRP 2.6 while not unlocked after the first reboot the phone was stucked.

What can I do?

My device respond to fastboot devices and fastboot boot recovery.stock.img boots the phone into stock recovery then  I have access to adb but not rooted I did adb push to /system/media to the stock WWE zip updatre file but still... the device reboot with the same Invalid Kernel message!

Is there any option to unlock the bootloader with a file like in HTC case fastboot flash unlocktoken Unlock_code.bin???

Please help me!!

OK Thanks for you're reading I got a solution!!!

Download Superboot R1


Unzip superboot to a folder

Then just download a stock kernel for your own version into that same folder (the file will be named after downloading "stockkernel.img")


Go to install-superboot-windows.bat on windows machine of course!

Right click on it edit then change from:

fastboot-windows.exe -i 0x0b05 boot boot.superboot.img
fastboot-windows.exe -i 0x0b05 boot stockkernel.img
Then save the changes and close the window.
Double click install-superboot-windows.bat to launch it when your padfone 2 is connected to the PC and turned on to "The Invalid Kernel screen of Death"
The device will reboot itself and start up like nothing happens but in my case I already did factory reset and flashed it back from stock recovery once before...
Have a nice day
I hope you could pin that post or rewrite it better to explain to so many people how to revert back after making an horrible mistake like replacing stock recovery while you didn't actually unlocked the bootloader properly!

didn't work for me...


Edit: after more reading and another person explaining the procedure above it did work!

What I did wrong the first time? very likely I didn't use the correct stock kernel...

And I put the folder on :/C

Well, after all it did work! Can't express how happy I was when i got a useable phone again.

On Android-Hilfe.de you can find a OP in German. It made me understand the different step a little better.

Hi, please excuse my english, is not my first language, not even the fourth i think...

I have the same problem with my padfone and with the trick that you post now i'm able to boot the phone, but after restart/shutdown, the problem appear again. How can i block this loop? I can't reflash the stock firmware even if i put the rar file in the folder.
