[Transformer TF300T Q&A, Help & Troubleshooting] kulm:
I just got my new tablet today... it automatically did all it's updates while it was charging - I unlocked it following the tutorials and some strange issues started happening where the recovery ROMs I flashed couldn't see the system partitions. I tried a few different recovery ROMs (TWRP, CWM) but both did the same.

The problem, now when I try and flash anything using the bootloader, my command prompt claims it finished successfully, but my tablet's green flashing box stops flashing and does nothing until I hold on the power button to hard boot it.

Any ideas? Here's the information I've been able to gather:

My device is doin the same thing i would go into fastboot mode and the green box would just freeze up but when i push the recovery it says that is was successful b ut the device doesnt take the recovery then when i tried to push it again it fails can anyone help
[Transformer TF300T Q&A, Help & Troubleshooting] mistyv:
That is what mine did and I thought it wasn't installing, but it actually did. Once I rebooted back into fastboot and selected RCK mine would boot into the recovery, but the internal and external sd card wouldn't mount. I tried TWRP and CWM, but no luck with either.

According to this thread http://xdaforums.com/showthread.php?t=2180376 it is likely an encryption issue with 4.2.1 and we will have to wait till someone finds a fix. I was apparently wrong about the encryption on my earlier post.
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
I'm not finding answers to this problem; just questions.

I can't get 4.2 until Asus drops the file on their site.

At this point maybe everyone put this area on hold for a few days till we can get the full download and try to figure out what is happening and how to resolve these issues. Try to use your unit as it is for a few days and avoid possible bricks.
[Transformer TF300T Q&A, Help & Troubleshooting] sbdags:
I have a full system dump of 4.2.1. Just extracting the bootloader and flashing it causes recovery to think it is encrypted. Custom recovery that is. Also I noticed that the 10.6.1.8 kernel doesn't like some updater-script commands. Finally there is a new file in /system/etc called recovery-resource.dat. I wonder if Asus has put some measures I in place to stop customising?
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Thanks for the good info. That explains a lot.

Were you using the update-binary from 10.6.1.8 or an earlier version?

Great catch. I just checked and we now have a different version of update-binary. Now I need to revisit my edify scripts.

Thanks!
[Transformer TF300T Q&A, Help & Troubleshooting] ryuken11221:
Well I'm still running 4.1.1 I haven't be able to upgrade to 4.2 just as yet so I'm not sure what the issue with my device is I just restored it back to back to factory for work purposes and now I wanted to root it back and install recovery now this
[Transformer TF300T Q&A, Help & Troubleshooting] sbdags:
I haven't actually flashed all of it but tried to make it compatible with my TF700. I also tried 2 or 3 different updater binaries and they made no difference.

Specifically format now wanted 5 args where only needed 4 before. No idea what the 5th is. Package extract file didn't like me writing to /tmp but was OK with /data/media ..... Weird

Looks like a permissions thing?

Fastboots freezing do to misc folder not being formatted.. every guide for a fix was the same. (As im sure you know) except the format misc. Was the only difference between the other methods.. I was skeptical. But as I stated . I had to literaly wipe the dust off my tab. Just that one little command via fastboot. And I flashed the latest asus stock blob. Flashed and booted iike a boss..
[Transformer TF300T Q&A, Help & Troubleshooting] Deangus:
Just to throw in my confirmation. I was in the same boat as Godly...had to wipe the dust off my tablet and give it a full charge, but formatting the misc folder made all the difference. Can't pass on enough thanks to everyone who figured this and saved me the cost of a new tablet.
[Transformer TF300T Q&A, Help & Troubleshooting] 8BitVoxel:
The above methods are 100%

Doing the long list of erase commands inc

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

100% fixes the bricked device, as long as you have fastboot, even when flashing didn't work before. I had the Same issue as all these guys, was just about to go to ebay and buy a Mobo, don't do it. just run these commands and your done, thank that dude or even donate, he saved me $100 and some!!

[Transformer TF300T Q&A, Help & Troubleshooting] schkeet:
Fastboot is still freezing for me after all the erase commands run successfully (system recovery userdata boot misc cache) but when I go to flash the blob i get

erasing 'system'...

Here it will freeze for 10-15 minutes then say

OKAY [2.000s]

Sending 'system' <800927 kb>...

So I left it like this all day yesterday and most of today. No change so I finnaly hit Ctrl+C..fastboot cancelled the flash but i no longer got any response from the tablet until I reset it and started fastboot again...I tried to use the older firmware release that you guys would have used in august but I'm getting the same issue...

One thing I'm noticing is my bootloader reads

My tab still boots but....

Here is my situation. Just bought a gently used ASUS ME301T due to the great reviews. Rooted using motochopper, unlocked. I boot the tablet into fastoot mode. Can get a serial number return when I enter "fastboot devices" command. Can get the tab to reboot when issuing the "fastboot reboot" command. However, when I try to push a recovery file, the green highlight behind the "rck" icon freezes. The computer says it is sending and completed. But alas, recovery doesn't update and I have to hold down the power button to reboot.

So my question is, should I simply format the misc folder BEFORE I issue the command to write the recovery? Due to so many people nearly bricking their devices for good, I would like confirmation before I try it that people that are unlocked, rooted, and can still boot their tab had fixed the flashboot freezing issue this way. The only thing I was able to decipher from those that have used the "fastboot erase misc" are those that were in a bricked or bootlooped state, which I am not.

Additionally, I am on the 10.6.1.25 firmware.

Thanks!

and the tablet just froze on Bootloader when connected to the pc ready to use adb.

I've connected my tablet to the keyboard and it didn't froze and flash again TWRP or CWM.

Only works if you have the keyboard otherwise it wont work

Not an issue. We were talking about the new update-binary that Asus used to process their commands to install this update.

Something not seen before but needed to flash recovery, roms and such to get out of this mess.

I'm in the same boat. I have TWRP recovery, fastboot won't flash anything. It says successful, but the tab freezes and it doesn't take. If we can't update to the working TWRP, we are screwed. I have no main OS. Any updates to get it to take a flash?

[Transformer TF300T Q&A, Help & Troubleshooting] markymark567:
you MUST flash the compatible recovery for the 4.2 bootloader!!!! if you are not flashing the specific twrp patched for 4.2 bootloader then that is your problem. the new bootloader remaps the partition layout so only the patched version will mount partitions. and as far as i know there is not a patched cwm yet(i could be wrong)
[Transformer TF300T Q&A, Help & Troubleshooting] Goddly:
any change on the hanging bootloader issue???
[Transformer TF300T Q&A, Help & Troubleshooting] sevenalive:
No. I think we are screwed. I can push files with adb, on reboot they all disappear. I was thinking if it was possible to push the changed TWRP files within TWRP with ADB. Then get it to mount the drives without rebooting.

I tried various flashing, various img and blob files, nothing is working. erase cache throws a write error. No idea what could be causing the freezing.

I contacted Asus, they quoted me $90 to flash it + the shipping of the device to them. I don't know if I want to spend $115 to fix a tablet that is worth $300 on sale. I think $40 is fair to charge for flashing.

Instead, I think I'll just buy the next iPad. Android tablets are still neglected and unimportant for app devs.

Though I appreciate thr help. But the name of the thread tends to suggest that a hanging bootloader wont allow me to flash . I have tried those steps. Though . I erased my recovery to flash new. Which as the thread title states again.. is not achievable at this time...
[Transformer TF300T Q&A, Help & Troubleshooting] sevenalive:
Well I'm sending mine off to asus today. Longer I wait, longer I don't have a working tablet. I'm hoping the rest of you do the same, I'm going to include a letter stating the problem. The bootloader is freezing on fastboot flash, seems more like a bug in ASUS code or oversight. I don't expect them to fix it for free, but I have a tiny bit of hope that if enough people have this problem, they will do something about it. At least help the people who won't send it off.

Another thing I noticed in their warranty, If the serial number sticker is gone, the warranty is void. Mine got to a point where I just peeled it off and saved it. Such a horrible placement and an easy excuse to escape warranties when they know the serial accessible in other ways, including software.

I'll update people when I get the call for the repair cost. If it's over $90, I won't pay it, that's just extortion.

New member, same issue here

Hi guys,

I have run into the same issue as Goddly. I was at first able to flash a custom recovery and tried both CWM and TWRP. After the last CWM I tried, I am now completely stuck and cannot flash anything without the device seemingly freezing. I have to reboot it via the power button after I get the "sending" and "writing" confirmations from fastboot. The only thing that changes on the screen of the device is that the box stops flashing on whatever it is highlighting. If I try to boot to recovery or directly into Android I get an unrecoverable bootloader error.

I downloaded a stock ROM from Asus's website but could not get it to flash to system. Since no "flash" commands work anymore, I decided to try "update".....

I ran a "fastboot update whatever.zip" but was informed that it doesn't contain "android-info and android-product". I created some blank txt file and threw them into the Zip, and then tells me that boot.img needs to be in the zip file. UGH! By falsifying some files, I discovered I need at least these:

boot.sig

boot.img

recovery.img

system.img

Is there any way I can acquire these files? Are they inside the blob file and can they somehow to be extracted?

I found I tool that runs on Linux called unpackblob, but I haven't tried it yet. Do you think that might work, or am I going in the wrong direction here?
[Transformer TF300T Q&A, Help & Troubleshooting] kulm96:
Agreed... It doesn't make sense to me why I'd be able to flash to TWRP and CWM 10 times, then all of a sudden lock up when flashing... For a while I could sitll boot into TWRP and use ADB but to attempt to troubleshoot the flashing problem I did a fastboot erase on my TWRP, which worked... but still couldn't flash a new recovery... very strange - gotta be a bug because nothing changed that I can think of between it flashing and hanging.
[Transformer TF300T Q&A, Help & Troubleshooting] sevenalive:
Yes use that tool, the filenames will be different.

SOS is recovery, LNX is boot APP is system.

I have my doubts it will work, will try myself.

Unfortunately it didn't change my results- it still freezes on the flash. If I get past that, I assume everything would be fine, but that is one heck of an obstacle. Any thoughts? Any other tools or modes to do this? What is the purpose of APX mode?
[Transformer TF300T Q&A, Help & Troubleshooting] pr_s14:
Please keep us updated. I tried adding txt files to the zip a couple days ago, but it didn't change the error message. I'd love to know what you did differently.

I also tried the "oem unlock" command and although it accepts (and the device stays connected - ie no hanging) it does nothing to help with the flash hang issue.

PS- Has anyone who has updated to 4.2.1 successfully, tried the new unlock tool on ASUS' website?

I actually did not unpack the stock blob I downloaded, rather I tried to just flash an SOS file and some others from another rar file I downloaded from these forums.

I have a blob file from ASUS, and I have BlobTools downloaded, but can someone help me compile the BlobTools to make it work in Linux? I have a Linux PC, but I'm far from a Linux guru. If someone can help me with that, I will try to unpack it, create a ZIP file with the extracted data, and then try a "fastboot update" command with it. Clearly at this point, "fastboot flash" just isnt' happening. My only hope is "fastboot update", but I just have to get BlobTools working first. Can anyone guide me in this?

Nevermind! I found a working GUI for Windows that I will try tonight around 7:30-8PM. I will let you guys know how it goes!

If you want the tool to extract your Blob, use this:

http://xdaforums.com/showthread.php?t=2012033

The GUI part doesn't work right, but just open CMD and run blobunpack [blob name]. You will get a bunch of files. Here is how to identify them:

blob.APP - system.img

blob.LNX - boot.img

blob.SOS - recovery.img

blob.EBT - bootloader.bin

blob.PT - Partition info

This is my last resort, so wish me luck!

I tried flashing those files myself, didn't work either. My bootloader says it's unlocked though. Although right now that could be a lie. Flashing the stock stuff might have caused a problem. I did so many things trying to fix it.

[Transformer TF300T Q&A, Help & Troubleshooting] Deangus:
You can chalk one more up to a semi-bricked condition.

I, too, unfortunately tried switching to a custom recovery manager (TWRP) after the latest OTA update. All seemed well until I attempted to flash a custom firmware; now:

1. Able to access Fastboot.

2. Able to access ADB.

3. TF300T always boots straight into TWRP unless you use the "ADB reboot bootloader" command.

4. TWRP is unable to mount /cache, /system, etc.

5. All further updates don't stick.

From all I've read here am I correct in my understanding that it's due to the multi-user, encrypted nature of the latest version of the bootloader? In everyone's experienced opinion, is this likely to be a future fixable problem, or should I be saving my pennies for Asus' support folks?
