The cable I have says ASUS on the connector so I'm pretty sure it's OEM.

I'm based in Ireland so the Caseen cable is expensive (with delivery added) and I'm not sure if it's an OEM cable.

I think I can assume that I do have the correct usb cable.

Do I have any other options for trying to fix this?
[Transformer TF300T Q&A, Help & Troubleshooting] das chaos:
The code you posted seems quite right, so I don't think it is the cable. If you can successfully erase partitions, you should be able to flash recovery. I would advise to use another recovery.img. I think I remember having had the same issue with one of the TWRP out there. Not every TWRP fits to a given configuration.

The TWRP which served me allways good (on tf201 and tf300t) is GEASS's here:

http://www.androidfilehost.com/?fid=23329332407580523 but it partitions /data to f2fs

...you might want to give it a try.

Reliable is also Scanno's TWRP here:

http://www.androidfilehost.com/?fid=23329332407579270

If that don't work I would recommend to nflash stock and start all over again (fuddling a lot with my tabs I have to do that from time to time)
[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
The extremely short times for the wipes (> 1 sec) looks very suspicious to me. I don't know why fastboot is not reporting errors, but I suspect it's not actually doing a d** thing.

How old is your fastboot version?

I seem to remember someone having a similar issue and solving it by getting a later fastboot and adb.exe (you can extract them from the latest SDK download).

[MENTION=4968172]berndblb[/MENTION],

I got the fastboot from a link on a forum and I'm not sure of the version. I think that might be a good first step. I'll download the latest Android SDK and pull out the fastboot and adb executables.

[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
you said u used linux as well - there you should always have the latest versions and for compatibility reasons i would continue using that for the time beeing.

the only thing off to meare your times . the erase commands are quick but not that quick. if you can flash a recovery as mentioned before use an older one and / or try the different versions. im on a twrp 2.5.?.? version on my tab.

Hi sbdags,

It's good to hear that I've not bricked it yet !

Yes I have created a script with all the commands in it. The last post was just a copy/paste to show output from the flash commands.

So the hanging of the bootloader when trying to flash happens a lot?

Is it normally a different version of the recovery image that fixes this issue?

I was wondering if there was any way to pull logs from the tab but I don't think I have usb debugging enabled so there may not

be much to pull.

Is there a way to pull logs or is there a way to remotely enable usb debugging?

Hi Buster,

Sorry for taking a while to get back to you. Not had much time to get back to this with the kids and holidays!!

So back on track to try and get this sorted.

I am still booting into stock, in my bootloader screen I see the following

Key driver not found.. Booting OS
Android cardhu-user bootloader <1.00e> released by "WW_epad-10.6.1.14.10020130801" A03

I've tried the various twrp recovery images from 2.5.0.0 - 2.7.0.0 and always the same issue.

When I try to flash the tab hangs and I need to do the hard reset (pwr + vol down) to reboot into bootloader. It seems to hang during the actual flash command

sudo fastboot -i 0x0B05 flash recovery openrecovery-twrp-2.7.0.0-tf700t.blob

Are there any logs I can pull from the tab or do I have any other access to it?

thanks

[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
No - that's what he meant. You can still boot into Android, right?

Flashify is an app that can flash the recovery from within Android.

To check your fastboot connection, do any of the following commands work?

fastboot reboot

fastboot reboot-bootloader

Also, you're not trying this connected to USB 3.0 port, right? If you did switch to a USB 2.0.
[Transformer TF300T Q&A, Help & Troubleshooting] knoxor:
thanks for the reply.

I'm not able to boot into android so flashify is not an option for me. I'm getting stuck in a boot loop when trying normal startup. I have tried to flash stock rom from sd card but it also loops. It starts the flash process then after a minute or so it restarts and continues. I don't get any errors displayed trying to flash this it just seems to loop.

The fastboot commands do work (fastboot reboot-bootloader)

I've tried installing twerp custom recovery but the process always seems to fail at the write command e.g.

When trying to flash stock rom using this command

fastboot -i 0x0B05 flash system 14.10.blob

The tablet hangs when this command is executed and I need to restart to get back into bootloader again.

I've tried this in Windows and Ubuntu with the same results. It looks like I'm connecting to the tab and the fastboot commands work but as soon as I try to 'write' to the tab it hangs.

I'm guessing it's either a permissions issue (not sure how or why) or maybe the ROM is knackered and can't be written to at all.

I've been at this since May this year and am giving up hope. From what I can see it's not worth sending it back to Asus to repair it.

Any ideas where I go to from here ?
[Transformer TF300T Q&A, Help & Troubleshooting] Berend de Boer:
Try fastboot format. Perhaps by clearing a bad filesystem the system flash will proceed.
[Transformer TF300T Q&A, Help & Troubleshooting] Exposure:
With help from this thread I succeeded in pushing a stock rom, so my TF300T is usable again (Thanks!), but I would like to put a custom rom on it.

I've tried many different TWRP images but I consistently get the the unable to mount /cache (and system, data etc) errors. Which is weird since I don't think there're any issues after booting the stock Asus rom. I think I initially messed it up by flashing a CWM that wasn't suitable for 4.2 bootloader. After pushing the asus blob with fastboot, recovery was wiped. So I reinstalled many TWRP and CWM images. Most succeed to boot, but can't mount any partitions. I can mount an external sdcard, but flashing fails. I've read some threads about using nvflash to re-partition the device, but it doesn't appear to be supported on 4.2 non-rooted device.

Any tips?
[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
The recovery has to be compatible with your current bootloader and the rom you intend to flash.

Since you did not post either, it's kinda hard to give any advice.

Also post the recoveries you've ried already.
[Transformer TF300T Q&A, Help & Troubleshooting] Exposure:
I'm not sure of the bootloader version. From what I read it's supposed to be on the fastboot screen, the version there corresponds to the stock firmware version: V10.6.1.27.5. I haven't decided on a custom rom yet, was going to try a couple of different ones. I've been testing with a daily CM11 zip. Can you explain a bit about bootloader compatibility with rom? I guess there could be issues with the filesystem, but I don't think it matters in my case. The recovery fails to mount any filesystem except the external sdcard, and flashing a rom fails immediately because no internal filesystem can be mounted, i.e. it doesn't get stuck of refuse to boot after flashing. Formatting /cache fails as well, block device (mmcblk0p8, iirc) doesn't exist. I've tried about 10 different TWRP recovery images, 2.8.0.1, 2.8.0.0 and a couple of older ones (2.6?) that were specifically linked from threads like these to solve the mounting issue. Unfortunately I don't have access to the pc that I used this afternoon so I can't give a list of exact versions I've tried.

I'd say the partition table is screwed, but if that's the case why does stock rom boot and run without any noticable issues?
[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
I don't have the TF300, but I think you either need scanno's modded TWRP 2.7.0.1 or the TWRP 2.8 timudru links to in the installation instructions of his KatKiss rom.

https://www.androidfilehost.com/?fid=23329332407579270

http://xdaforums.com/transformer-tf300t/development/rom-t2817919

Install either of them. If you still get the unalble to mount problem, you may have format /data. You'll find the option under Wipe > Advanced.

Your bootloader is ok, but you have to read the OP of each rom you want to flash very carefully for instructions on bootloader and recovery requirements.

Good luck

Hi,

Just some more details:

I'm currently on stock rom "WW_epad-10.6.1.14.10-20130801 A03 (from top of bootloader screen) and I have my tab unlocked but not rooted.

I have previously tried to erase all the partitions before attempting to issue any flash commands.

I was able to format the system partition, this seemed to work but again the tab hung and I had to restart to get back into bootloader menu. I tried both the below commands in Windows and Linux.

Should the tab be hanging after these commands ??

C:\adb>fastboot format system

This is the output from trying to flash a recovery blob. Other people have commented that the time is very quick.

Again, this command causes the tab to hang.

Make sure you have version 2.8. And make double sure your download is correct, so verify hash signature or file size, whatever twrp says you should check.

After flashing the recovery, you should be able to boot into the recovery. If twrp does not come up, flash latest stock, verify that boots and works, then flash twrp again.
