Hi I am running a TD300TG with ICS and setup nvflash as well.
Now I wanted to upgrade to JB but already flashing JB with TWRP gives me a failure after a while.
In ICS the update file is as well recognized as an update, but this will lead me to TWRP as well...
I tried following this guide: http://forum.xda-developers.com/showthread.php?t=1845377
Maybe you already did it successfully?
I am roote, unlocked, nvflashed...

Is there a way to flash to stock using a computer? (similar to Odin for Samsung and RSD for Motorola)
My screen is having issues and cutting out and it is no longer working so I'd like to flash it to stock before I RMA it.
just flash the blob file thats in the stock zip via fastboot
think the right command was
fastboot -i 0x0B05 flash staging blob
this take a long time, so don´t panic cause you see nothing in the fastboot window. Wait till your pad is rebooting.

First you need to provide more info (i.e. did you tried to flash something before this issue occured?, your device is unlocked?) and maybe we can help you.
Yes tablet is unlocked.

Can't mount anything....
Then i used commands:

I can't read the error from that video but i think you should flash a boot.img via fastboot and then flash CWM or TWRP recovery the same vai (via fastboot). BTW you have to use a boot.img from a JB rom.

Error is 0x000000000
Where i can get boot.img?
Then i extract blob file, i get 5 blob filesblob.
HEADER – Header stuff (ignore it)
blob.APP – system.img
blob.LNX – boot.img
blob.SOS – recovery.img (e.g. regular boot.img)
blob.EBT – bootloader.bin (ignore)
Do i have to rename blob.LNX to boot.img or i should't ?
Do i need to erase all system boot recovery data?
Thanks.

You made the same mistake I made:

APX means you get to use nvflash, right?
I wish I was on the same boat.
Yes i can use nvflash.
but i can't restore my bootloder
maybe you know what to flash?

What do you mean with "Yes i can use nvflash"? You already used the NvFlash tool and have the backup files or is just the fact that you are able to boot in APX mode?
As for the other question, yes rename the blob files ( blob.LNX - > boot.img) and flash from fastboot (fastboot -i 0x0B05 flash boot boot.img). Make sure your battery is full, just in case.
Try to flash the recovery.img, boot.img and system.img using the abive method.

Being able to boot in APX doesn't mean you can use NvFlash to flash your device.If you never used the NvFlash tool to backup your files (and gain NvFlash access) you won't be able to do it anymore because a 9.4.5.26 or lower bootloader it's needed.
I'm not sure if the follow procedure will work but you could try to flash the complete blob via fastboot (rename the original asus blob to something like " tf700t.blob " , something like this : fastboot -i 0x0B05 flash staging tf700t.blob
Someone please correct me if the " flashing to staging" procedure is different.

ATM there's no way to do that ,Asus locked the bootloader pretty tight this time.
If you still can't manage to fix your issue i would recommend you an RMA ticket from Asus.
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.

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]
writing 'recovery'...
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
erasing 'system'...

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 )
hope i could help you out!

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?
Well, what happened is :
that i was trying to root my Transformer tf300t
and i got as far as unlocking the bootloader
so i was having trouble flashing the twrp recovery image
and i think i accidentally erased the stock recovery image
so now my tablet it's not (full bricked) still boots up but doesn't have a recovery image
and now when i boot it into bootloader mode and try to go into RCK it just gives me this
error bootloader unrecoverable 0x0000000 (in red)
how can i flash the stock ROM again if this error ?
anybody ?HELLP

Please try this:
Go to Asus and dl the latest Stock. Unzipp it 2 times. You should have a blob file now in the extracted folder. Put this blob in your fastboot folder.
Open cmd and type:
fastboot -i 0x0B05 flash staging blob
Let it run. It seems that nothing is happening for about 5 Minutes. The whole thing can take up to 20 Minutes, so just stay calm and wait till it’s finished.
Now you should be back to full Stock with Stock recovery. Good luck!
THanks !

Thank you ... it worked i think
but i used a little different command line i used :
fastboot -i 0x0B05 flash system c:\adb\recovery.blob
now i'm still having problems trying to flash custom recovery i want to root the Tablet
what the problem seems to be for me is that i boot the the tablet (tf330t transformer 4.2.1 JB )
to fastboot mode then i get the 3 choices (RCK, Android,Wipe Data)
but when i try to flash the TWRP recovery img with Fastboot it always gives me an error saying (error cannot load img file)
is there anyway to fix this ? and does this root the tablet?
Dear daveSAPIEN can you give us more information about the file used during the flash , actually am facing the same problem as you but nothing seems to work
thank you
