Hi all! Please help me
I booted at TWRP and tried to restore the stock ICS..
now i'm stuck at bootlogo..
when I turn it on with vol down pressed I can select fastboot mode.. it says "Starting fastboot usb download protocol" but I cant get the device listed at ADB devices
i doubled installed all drivers following the noob thread.. but no device listed with adb devices...

When you go into fastboot, try fastboot devices instead. If you have that you should be able to flash in recovery if you need it and possibly use that to flash in a stock ROM.

00000 fastboot
this is good?

can I flash TWRP thru the methoed described at their website?
Install Fastboot Method:
You will need fastboot for this method. Download the above file, check the md5, rename to twrp.blob and put the file in the same directory as your fastboot.exe (unless you have /platform-tools in PATH then you can flash from anywhere). Turn off your device and boot to fastboot (power on while holding volume down, then select the usb icon and hit volume up to confirm). The device will now be in fastboot mode. Plug the device into your computer. Run the following command via the command line:
fastboot -i 0x0B05 flash recovery twrp.blob

flashed the twrp.blob but didn`t make effect
i'm still stucked at bootlogo and accessing my tf300 only thru fastboot
which recovery should I try to flash?

My mistake was that a long time ago I made a full backup.. including boot, cache, etc.
When I restored this backup I think the TWRP has been overriden..

Compiled from CM9 sources.
Recovery Image : ftp://94.23.233.147/Smartphones/Liquid Glow/Recovery/CWM-6.0.1.1-E330.img
Your bootloader have to be unlocked to flash the recovery image.
To reboot in fastboot mode :
Code:
adb reboot bootloader
or
Code:
Turn off your device, then plug USB cable while pushing Vol-.
To flash the recovery image once booted in fastboot mode :
Code:
[I][B]Optional[/B] if your bootloader is not unlocked[/I] : fastboot -i 0x0502 oem unlock
fastboot -i 0x0502 flash recovery CWM-6.0.1.1-E330.img
Is there any way to root Glow?
Any tutorial available?
EDIT
Found it in vache's server ftp://94.23.233.147/Smartphones/Liquid%20Glow/Root%20&%20Reco%20Glow.zip
Settings> Developer Options, check the USB debugging.
First run unlock.cmd
reboot
then root.cmd
reboot
You are rooted!
it's possible to unroot this device?
after i follow instruction to unlock the device and i press Vol-, it blocked on fastboot mode now?
how do I get rid of the remote error:

FYI, that's still the old recovery and it has some screen glitches.. couldn't find the 6.0.1.1 version anywhere - do you still have it?
it's going to be quite a pita getting the updated recovery, the recovery builder on koush's site produces glitchy recoveries and the old one lacks some functionality

This is great, have been searching this for a long time, unfortunately the link seems to be down.
Possibly any mirrors to this file?

Unrecoverable bootloader error but not Bricked!

So I unlocked my tf300t and flashed cwm to recovery.
Everything seemed to go fine.
When I would go into cwm it was not able to mount or access any other part of my tab. I figured ok erase/format the recovery partition and try TWRP. So I booted to the bootloader, using fastboot I erased recovery but now whenever I go to flash a new recovery my bootloader either freezes or I get an Unrecoverable bootloader error 0x00000000 (not sure if thats the right amount of zeros but there are no other digits in the error code.) I can access fastboot and adb but it doesn't seem like I can flash using fastboot and I just don't feel comfortable trying with adb. Also I can access fastboot only from the bootloader screen and adb only after I boot into my current rom (stock 4.2.1)
I guess my questions are this:
How can I format my recovery or flash a new recovery?
Were the mount issues I originally encountered going to be solved with a new recovery?
Please help!
Have you tried installing stock rom (from Asus support page) using Fastboot? It should also put stock recovery in your tablet.
Not sure if it is going to work, but it's worth trying though.
1st this is not for the dev section. You should ask questions in the Q&A section.
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 its finished.
Now you should be back to full Stock with Stock recovery.

I had this problem too. But on 4.2.1 you can push file blob, and then it's can't run because stock recovery dead.
Were you able to fix the stock recovery issue?

No, I was not. I also have the unrecoverable bootloader error but I have a working device. I downloaded the latest firmware, followed the steps through fastboot and the same thing keeps happening where as soon as you try to enter a command through fastboot the green box stops flashing over rck and even though the cmd prompt window tells you something is going on nothing happens on the tablet end. It freezes. hard reboot and you end up back with a normal working device, no changes and a corrupt bootloader.

I was having this problem earlier - a new bootloader came out when they went to 4.2, but most of the instructions online don't reflect this. You need an updated recovery image, which usually has the name recovery-jb.img instead of recovery.img. When you're searching make sure the instructions mention 4.2 and jelly bean.
However, I've only managed to get one step further - have now get into clockworkmod recovery, but as with the OP I then couldn't mount anything inside CWM. I tried another instruction set which involved unzipping the ROM and using adb to push over the .blob. This hasn't worked and I have now got a pretty much bricked device - it either bootloops on the asus splash screen, or loads into CWM.
I've found that even when youre in CWM you can type "adb reboot-bootloader" into the terminal, which forces the RCK/android/wipe data page and fastbook to appear. I've also tried to download the latest stock firmware from ASUS, unzipped it to get the stock .blob out and into my fastboot directory, then run "fastboot -i 0x0B05 flash staging blob" in the terminal, as per mikaole's suggestion. This takes a while to push over the 80mb .blob, but after it says it's staged it says "done" then nothing happens and it's still bricked. hmm.
No one's figured this out? I tried flashing the blob file and my system won't boot at all
My solution
I have the same on my TF300t and A700 - but it seems i just managed to get my TF300t back
i tried all fastboot (reflashing recovery, boot, system etc) no dice - especially since writing system was done after 3 secs all the time.
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 erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot 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

Did your tablet seem to freeze after flashing via fastboot? When I push blob, the console shows that it wrote, but then fastboot on the tablet freezes & I have to manually reboot, putting me right back to the drawing board.

nope. do you use the original cable on usb 2.0 and connected to your pc not a usb hub? should work. if not try a diffrent pc - sometimes usb chipsets make problems.

I get invalid argument to all of the erase attempts and the minute I try to push the blob the flashing green icon in fastboot mode on the tablet stops. The command windows says the flash went fine but the tablet is unresponsive and must be reset. Infact any fastboot command that pushed something to the tablet causes it to look up ( indicated by the green flashing RCK icon freezing on whatever phase of green it had at the time)

[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

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.

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.

Thank you! Looking for days now. I installed TWRP 2.6 and CWM 5, 6 and touch. All the same problem. Flashed the TWRP from your link and everything works fine. Thank you

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]
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'...
OKAY [ 1.695s]
sending 'system' (800935 KB)...
OKAY [133.121s]
writing 'system'...
OKAY [153.973s]
finished. total time: 288.789s
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?

[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.

Unable to boot into recovery but able to boot system

Hi I wonder if anyone can help me. My tf700 is running Zombi-Pop 5.1.1-OMNI-DEODEX RC2 . I may have wrecked my recovery and boot-loader. My Infinity is unlocked and rooted and had TWRP 2..7.00 or roughly that. In preparation for installing KatKiss 6.0.1 . I updated TWRP to [RECOVERY] KANG TWRP TF700T [email protected] JAN 4 from within TWRP and it completed ok. When I went to reboot into recovery I got a unable to boot error boot-image is unreadable X000000 or something like that, But I am able to boot the system which seems to be working OK. Does anyone know if the is anyway for me to re-flash a working recovery or am I stuck without a recovery? If anyone can help me with this I would much appreciate it.
Cheers Al-Man
ps. I have read loads of posts but I am still unsure as to what is the best course of action. I don't want to make it totally useless.
Your bootloader is fine or you would not be able to boot Android.
Kang TWRP 2.8.x is fine for any current rom so that is not the problem either.
Did you let the tablet reboot after the recovery flash? Sounds to me as if that was when things went south.
So fastboot flash the recovery, then reboot to system once before you try to boot into recovery.
If you don't know how to fastboot flash it's high time you learned it.

You could also use flashify or dd commands if you have root.

Thanks for your quick reply bernbib. I have tried to fastboot and load a new recovery image. I am able to see the device using the fastboot devices command. When I flash a new TWRP image it shows the following
twrp.img
sending 'recovery' (7038 KB)...
OKAY [ 2.801s]
writing 'recovery'...
OKAY [ 2.541s]
finished. total time: 5.343s
I then try fastboot reboot and all I get is
rebooting......
on the boot loader screen it reads just under the boot version
Starting Fastboot USB download protocol this is constantly showing every time I boot to the boot loader.
and then I reboot from the tablet and its back to square one .
Any Help with this problem would be most appreciated I can still boot to system but I am not able to access recovery.
Many Thanks. Alex

I have seen many cases of "unrecoverable bootloader error" but never that you could still boot into system with that error. So I have no idea what is going on for you, but the only method I know of to successfully recover from a unrecoverable bootloader error is to flash the Asus system blob in fastboot after fastboot erasing each major partition. We call it a buster99 and you'll find it here:
http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
Before you do that why don't you try to 'fastboot boot recovery twrp.img' instead of flashing it. You should still be able to use TWRP as usual, flash a rom with it etc. It just does not get installed on the tablet....
See if you can use the recovery that way...

Buster99 has been a tablet saver for many users.
But if you don't want to do the whole thing try to fastboot erase recovery, cache and misc, then flash TWRP again and see if you can boot it.
