hi,
I tried upgrading my tf300t from cm10.1 to cm10.2 . after a few failed attempts during which I am not exectly sure what I did wrong i got the device into a condition in which it only boots directly into CWM v6.0.2.3 without any option to do anything else. pressing power+volume down does not stop it from directly booting into recovery.

inside the recovery it says:

"E:Can't mount / cache/recovery/command/
E:Can't mount / cache/recovery/log/
E:Can't open / cache/recovery/log/
E:Can't mount / cache/recovery/last_log/
E:Can't open / cache/recovery/last_log/",

and i cannot mount any partition on the device. trying to access it from fastboot\adb has not been successful.
Any help would be appreciated.
thanks a lot,
guy

I now recall that at some point after trying to flash cm10.2 didn't work I tried flashing the offical asus firmware blob. after that the device successfully booted but when I tried to return to the recovery mode I still could not mount the /data partition. after that I tried some more flashing which brought me to the current situation.

new development -
after installing the universal naked driver i was able to boot into the boot loader using adb and I even can boot the device to the os, though no change when inside the recovery mode. if the device reboots it automatically goes into recovery and to reboot it I have to use adb again.

Flash the updated stock ROM again via fastboot to reset it back to stock. then flash the correct TWRP and then flash the CM 10.2 ROM you wanted.

like this:



Code:
fastboot -i 0x0B05 flash system blob
I've tried that and the device does not seem to be responding to the idea. in fact I dont think it gets anything I've tried to flash at all. the files do transfer but do not seem to install. after starting a flash with fastboot the device stops responding.

plus, the bootloader screen does not show the usb icon at all. I am flashing when the device is in the bootloader.
at the bootloader screen there is a message: "key driver not found"

OK you said it can boot into Android though. Use terminal emulator to install the TWRP and then flash the stock ROM from inside TWRP. Just make sure the TWRP matches your bootloader.

That means you are on the 4.2.1 or 4.2.2 bootloader. That bootloader doesnt have a USB icon, it goes directly to fastboot if it is detected and that is completely normal.

so, after doing as the guy in this thread - http://forum.xda-developers.com/showthread.php?t=2425581 says, I managed to make the device successfully reboot to the os by default and even make it reinstall the stock rom and than twrp recovery. the problem no is when entering recovery, it asks for a password which i do not know. when choosing cancel it gets me in but now it displays:

"E: unable to find partition size for /misc
E: unable to find partition size for /staging
E: unable to find partition size for /data
E: unable to find partition size for /recovery
E: unable to find partition size for /boot
updating partition details...
E: unable to mount /system
E: unable to mount /cache
E: unable to mount /cache
E:TWFunc::copy_log -- cant open destination log file: /cache/recovery/log
E:unable to set emmc bootloader message
E: unable to mount /cache"

when trying to install a different rom the recovery mode fails to access the internal/external sdcard.

thanks in advance,
guy

that means you probably flashed the wrong version of TWRP. Are you on the stock 10.6.1.8 or on a later version of bootloader? Those are different.

stock rom version 10.6.1.27.5 (build number JOP40D.US_epad-10.6.1.27.5-20130902)
TWRP 2.6.3.0

are those not compatible?

*
trying TWRP 2.5.0.0 or 2.4.2.0 made no difference.

Using twrp 2.6.3.0 -4.2 ? Or -jb?
I do not remeber which I've tried. which one should it be?

*

I tried them both again. both require a password at start and both fail mounting the partitions, showing

"E: unable to find partition size for /misc
E: unable to find partition size for /staging
E: unable to find partition size for /data
E: unable to find partition size for /recovery
E: unable to find partition size for /boot
updating partition details...
E: unable to mount /system
E: unable to mount /cache
E: unable to mount /cache
E:TWFunc::copy_log -- cant open destination log file: /cache/recovery/log
E:unable to set emmc bootloader message
E: unable to mount /cache"

Use the 4.2 one. The jb will result in a very bad brick.
