[Q] Internal and SD Can't mount in CWM

Hi all.
Im having some problems with this, and was hoping that some one here could help me.
I have unlocked my device, no problems.
Then i have installed CWM, no problems.
Now here my problems begin... I have copied a custom ROM zip file, onto my tablet. When i boot my tablet into CWM i get some errors in the bottom of the screen looking like this:
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
Now when i choose to "- Install zip from sdcard" and after that i choose "- Choose zip file from sdcard" i get this error: E:Can't mount /sdcard/
Then i try to select the "- Choose zip from internal storage" but then i get this error: E:Can't mount /emmc/
Basicly i cant do anything at all in CWM without getting errors, cant even whipe the cache or anything.
Can someone help me to find out what to do now. And hopefully how to solve this?
I can boot into my androind system without any problems.
Hope some one know's what to do. Thank you in advance.
Info:
TF300T
Android 4.2.1
Kernel 3.1.10-g6f31760
CWM-based Revovery v6.0.2.3
If there is anything else you need to know to be able to help me, please ask.
Have a good day.

CWM doesnt work with the 4.2 bootloader from ASUS. Only TWRP for bootloader 4.2 seems to work. You will have to flash TWRP 2.5.0.0-tf300t-4.2. Take note you need the TWRP version with the "-4.2" at the end. Flashing the incorrect TWRP version can brick your tablet.
Download http://techerrata.com/file/twrp2/tf300t/openrecovery-twrp-2.5.0.0-tf300t-4.2.blob.
Reboot tablet and hold volume down button while it's powering up to enter fastboot mode. Do not select any of the 3 icons (RCK, Android logo, Wipe Data) on tablet. Connect tablet to PC via USB cable.
On Windows PC, cmd window type:
fastboot -i 0x0B05 flash recovery openrecovery-twrp-2.5.0.0-tf300t-4.2.blob.
On tablet, wait until blue progress bar completely fills up.
On Windows PC, cmd window type:
fastboot reboot
That should replace your CWM with TWRP.

Hello ImmovableObject.
Thank you very much for you reply, that was excatly what was wrong.. Stupid me, not checking up on that. I actually flashed another version of TWRP, so i guess i was extreemly lucky that it did not brick my tablet.
But after i flashed the right TWRP its all good, everything is working as intented, and i can make backups and flash custom roms now. Thank you very much for your help
Have a good day all.

You are very much welcomed! I'm glad it worked for you.

I found this useful when I was struggling with CWM as well, very glad I was careful to pick the 4.2 blob
Thanks for the help!

Holy Crap!
I can't believe how stupid I was! I ahve always despised CWM yet I was using it on my TF300T. After searching and searching for a fix I came onto this. Great job man!

THANK YOU FOR THIS!! I too stumbled around with CM Recovery for about 30 minutes, dumbfounded by the fact that it couldn't mount either the internal or external storage. I did some research and that's when I came across this post. I can't believe they don't make any mention in any of the tutorials that CM Recovery won't work with the newest 4.2 bootloader from Asus.

Your method did not work with my TF300T, Please assist
@ImmovableObject , I've tried your method but for some reason my Tablet did not reboot with the command "Fastboot reboot" and i still get CWM-based Recovery v6.0.2.3 for recovery instead of TWRP. it did say the flash was OKAY.
Please Please help

That's strange.
Was your tablet running Android 4.2?
Try waiting a little longer (5 or more seconds) before issuing the "fastboot reboot" after the message that the flash was OKAY.
Things you could also try:
* Update your fastboot.exe to the latest version. You can do this via the Android SDK Manager on your computer. Fastboot is included under "Tools" > "Android SDK Platform-tools."
* Use a different USB cable.
* Connect cable to a different USB port on your computer.

Hello.
I have TG300TG that only goes to CWM-based recovery v.6.0.1.3 and can not mount sd card. I've tried the mothod described here, but I can't get to fastboot mode. When I hold vol down it only goes to CWM again and again.

I have the same problem, to actually get back to the bootloader and select RCK or Android do this:
Once CMW is loaded open command and do
adb reboot-bootloader
that also enabled fastboot again but I'm still not able to load TWRP
---------- Post added at 01:50 AM ---------- Previous post was at 01:13 AM ----------
So just like the previous few posts I too installed CWM and I can't reflash TWRP.
Here's the output from the console:
D:\Android SDK\sdk\platform-tools>fastboot -i 0x0B05 flash recovery openrecovery
-twrp-2.5.0.0-tf300t-4.2.blob
sending 'recovery' (6448 KB)...
OKAY [ 2.699s]

OKAY [ 2.254s]
finished. total time: 4.955s
D:\Android SDK\sdk\platform-tools>fastboot devices
???????????? fastboot
D:\Android SDK\sdk\platform-tools>
Device is unresponsive to any commands and must be rebooted manually. Once I reboot the device loads to the CWM Recovery unless I run "adb reboot-bootloader" and then I can choose to boot the ROM. So at least it's not bricked.

Fix
Found this posted by buster.
So if you're TF300T is booting directly to recovery and you can't get to fastboot do what I post above:
1. Let recovery load
2. With recovery loaded you can now use adb. enter: adb reboot-bootloader
3. You should now be at the bootloader screen (RCK, Android, Wipe screen). Do this:

Here how i restored my TF300T JB
download your appropriate lates firmware from Asus (WW, US etc.) and extract the zip twice so you have your blob file
install your device drivers if needed (i used Google SDK ones) (and as a Tip Win8 sucks for Fastboot stuff so try to get Win7 Vista XP for this)
Reset your device with a paperclip/needle (about 2 cm down of your sdcard slot) and hold vol-down to enter fastboot
(the folowing i did at least 10 times already but didn't erase misc)
fastboot -i 0x0B05 erase system
fastboot -i 0x0B05 erase recovery
fastboot -i 0x0B05 erase userdata
fastboot -i 0x0B05 erase boot
fastboot -i 0x0B05 erase misc
fastboot -i 0x0B05 erase cache
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob (this is my path - your's may vary depending where you stored your blob) ((also this was the first time i saw the loading bar while flashing)*
fastboot -i 0x0B05 reboot
* it also took a lot longer as it should:
C:\>fastboot -i 0x0B05 flash system c:\adb\TF300t\blob

im now setting my tab up to get back to CM (which initially caused this sh1theap due to autoupdate error, same as my A700 got bricked )

twpr is working
flashed twpr v2.5.0.0
works great so far, but it takes a little more time to load than cwm.

help!
right guys, I'm completely green when it comes to stuff like this so apologies if my questions are too daft.
I tried to root my tablet and forgot to back it up, tired few things I found online and got myself in a position where I can't use fastboot as my tablet is taking me to CWM recovery straight away and holding volume key and power makes no difference... any ideas? apart from throwing my table in a bin?

Stuck in boot loop [adb & fastboot access OK]

Hi all,
I've flashed CWM 6.0.2.3 instead of TWRP 2.5 to recovery partition after having unlocked the ASUS JB 4.2 bootloader using ASUS unlock tool V8. After that ASUS JB 4.2 was running well but not with root access AND i did the big mistake to use the wipe function in the bootloader ... since then i'm stuck in a boot loop with access only to CWM but i can't mount anything (internal or external sdcard) ! The good news is that i have still adb access under recovery => i run 'sudo adb reboot-bootloader' to access the bootloader menu which also provides me fastboot access ... the problem is than when i run 'sudo fastboot -w' in order to perform a wipe, the linux command hangs the tf300t after having erased and formatted the userdata partition (first one in the wipe process) !!!
Also, flashing system or recovery using fastboot works but i don't have the blue progress bar during the operation and the 'sudo fastboot reboot' command hangs the device ... for example if i run 'sudo fastboot flash recovery twrp.blob (i use the 42 version not JB or ICS one) i have a successfull output BUT fastboot is unable to reboot my device and when rebooted after pressing the power button for 8 secs i am back in CWM 6.0.2.3
I've noticed this output when booting the tablet to the bootloader menu : 'key driver not found booting os' and i've no clue about the meaning of this message => it seems that if i successfully flash TWRP this message will disappear ...
Any help would be greatly appreciated,
Have a nice day

I've exactly the same problem!
I tried to:
fastboot -i 0x0b05 flash system blob

On reboot the pad show the CWM interface.
I tried this:
Reboot the pad. When the pad activates the usb port, I tried: adb reboot-bootloader

[Q] After erasing the recovery with fastboot my LG p350 don't start

Hello,
I have followed a tutorial for solving the problem of "Fastboot mode started
udc_start()" from this thread http://forum.xda-developers.com/showthread.php?t=2131247 and something was go wrong.
I have done this steps in the sdk platform tools folder:
1- fastboot erase recovery
2- fastboot flash recovery recovery.img ( here i've got an error)
3- fastboot reboot
Everyting was ok until I have tried to write the .img file on the phone. I've got an error that I don't have enough space. I think I have deleted the recovery file and now it's stuck, because it's not booting. The 4 leds from the bottom it's flashing continuously and the screen remains to the LG logo. I have tried to connect the phone to the PC but the device it's not recognized anymore. I get this message in the adb tool "Waiting for device"
I really appreciate if it's someone that can help me

I have a p500 and I had the exact same problem as you. But I was able to fix it after a lot of Googling.
Can you get to fastboot right now? If so, make sure that the recovery you downloaded is correctly named "recovery.img" and is placed in the same folder as adb.exe is located. After that, type:
Code:
fastboot devices
into ADB. If your device is listed then proceed and type:
Code:
fastboot flash recovery recovery.img
If nothing comes up when you ask it to list fastboot devices you need to delete all of the drivers associated with your p350, and then reinstall them using a toolkit or PDAnet. Then go back and try fastboot devices again.

Can you pull the battery and then use the combination to get into Fastboot? If you can't get to fastboot, then the problem is beyond what I'm capable of doing.
Though, the problem may be that you completely deleted your recovery.

That is incorrect. The recovery does NOT have to be named recovery to use fastboot to flash it, although it does make life simpler

[Q] Softbricked Tf300t

Hi I have been reading a ton in the forums trying to figure out how to fix my tf300t. A few days ago I updated to the newest CM 10.1 nightly and when it restarted it was stuck at the Asus screen. So I have been able to hold vol down button and get to a screen that says
RCK Android [usb symbol] and Wipe Data
I have fastboot access and thought I would try to fix the problem myself by following instructions on another thread
"pyovue - If you have ADB access then unbricking it should be easy as you can push and edit any file on the system with it as well as fastboot? Or can ADB & Fastboot not mount (not just the sdcard) anything? If you don't care what happens to your tablet MB, then try this....
fastboot -i 0x0b05 erase system
fastboot -i 0x0b05 erase recovery
Then reboot (this should rid you of your bootloop to recovery and nothing should start)
Then download the stock ASUS Rom (from ASUS, look under Firmware)
Then try sending it with fastboot -i 0x0b05 flash system blob (you will have to extract two zips from the firmware files until you get to a file called "blob" then put it in your fastboot)
I almost guarantee if you have fastboot/adb working there is ALWAYS a way to fix it... only a hardbrick is impossible to fix.
"
I get cannot load 'blob' so I tried
fastboot -i 0x0B05 flash recovery recovery.img
seeing as I already had the recovery.img from when I first unlocked, rooted, and put cm 10.1 on it
please help I have no idea what to do and thank you in advance <3

What's the question again? If you have fastboot, you can always flash the system blob from your PC. Or you can push the rom (zip) to your internal storage, turn it off and on again. If you select rck on official recovery, it should look for the zip file on its own and proceed to flash it. If you have custom recovery, get to it and flash the same zip file. Make sure you have the right recovery for the rom though. Good luck.

[Q] Encrypted Nexus 4 rooting gone bad

I tried to root my Nexus 4 (Android 4.3) with this howto. I tried to use the "ClockworkMod Recovery Method" (which worked fine for another phone) but then, after the last step ("Reboot the device"), the phone did not come back correctly: the "Google" logo stays on for a few minutes (?) with an "unlocked" chainlock below, then the flashy and colourful "X" stays there, forever.
While in ClockworkMod recovery, I noticed that /mnt/sdcard could not be loaded, for whatever reasons. It just said "cannot mount /mnt/sdcard". Thus I had to install SuperSU-Busybox-Installer.zip via "adb sideload".
Now, after thinking about all this: right after unpacking the phone I set up "encrypted storage" in the Android security settings, so I need a PIN to start the phone (and then a PIN to unlock the screen). Could this have something to do with all this?
And: what do I do now?
Please help / point me to a relevant thread...
Thanks,
C.

[RESOLVED]
Update: found another thread, pointing to this AndroidCentral article that solved this for me! In short:
* Get factory image from Google
* fastboot reboot bootloader
Prepare with:
* fastboot erase boot
* fastboot erase cache
* fastboot erase recovery
* fastboot erase system
* fastboot erase userdata
Flash the stock image:
* fastboot flash bootloader bootloader-mako-makoz20i.img
* fastboot reboot-bootloader
* fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.84.img
* fastboot reboot-bootloader
* fastboot –w update image-occam-jwr66v.zip
The last command should reboot the phone, this did the trick for me. Sorry for the noise...
