can't boot into recovery anymore I am using CM10 nightly version and TWRP for tf201. Wanted to try the unofficial CM11 version android 4.4 on my tablet and it says that is not compatible with this recovery, so I downloaded the latest version of CWM 5.8 from its website and using adb fastboot (and second time with the tablet terminal) flashed the new recovery over the older one.
Now the problem is I can't enter the recovery mode, it gets stuck while entering the mode. I tried that procedure with two more recent version of CWM (both touch and classic) and also its ROM manager but the problem persists. Some info:

1- I have my device unlocked, rooted
2- adb fastboot said completely Done while flashing
3- i could see the blue bar completed on the tf201 device and then i used fastboot reboot.

Any suggestions?
I've found that if I run into problems with the custom recovery, I can get rid of it altogether by re-flashing the stock firmware, and then I can install the custom recovery again. You have a different device, but that's what works on a Samsung Galaxy S4, so it might work for you. Of course, there's always the possibility that if you try installing CWM again you'll run into the same problems, but at least that should let you start again from square one, as if you had never flashed a custom recovery in the first place.
