Allright I will try that and see if it works.

I should add that I have the stock 4.0.3 ICS rooted and unlocked (top left on boot)

and trying to update to the latest firmware US_epad-user-10.6.1.27.5
[Transformer TF300T General] zorglub!:
Same situation..

device TF300TG under Android 4.2.1 unlocked ( using Asus Unlock-v8 )

Universal Naked Drivers 9.73 installed

device recognized ( adb device --> C5OKCT090153 )

pressing Pwr + Vol- gives a message in top left of screen

android carhu-user bootloader <1.00> release by "WW_epad-10.6.2.10-201330918" A03

key driver not foun..Booting OS

Any idea ?
[Transformer TF300T General] zorglub!:
Finally everything worked...

my fault...I was not unlocked...

I had thought that, downloading and executing Unlock_v8 was enough.

I realized that it only drops an app (Unlock device ) which is the one who does the unlocking job.

Once that done, installing TWRP was just a joke ( even if you have a strange message about missing driver key...but, immediately after, you got a new line saying your machine is ready for fasboot...)

pushing the blob file is done in around 10 seconds..

Once TWRP is on board you just use it to install the Update -SuperSU which roots the tablet

Thks for all guys...you've all been of great help for an Asus noob like me

[UNLOCKED BL] Method 3: Update using TWRP recovery

After flashed the firmware, do not need to reflash TWRP recovery again.

My process is right?
[Transformer TF300T General] Wiskid15:
Very confused...

I'm currently running stock US 10.6.1.14.8. I successfully rooted. I have unlocked the BL. I cannot seem to load TWRP by following any of the guides on here. I've tried GooManager, it says that it loads, but when it reboots, it reboots right back into Android OS. I've tried using fastboot. I get an error "FAILED (remote: (InvalidState))". I have proper drivers installed, but when I do "adb devices", I don't get any results (when booted after holding power and vol down). On the bootloader screen, in the white text, it reads "Key driver not found... Booting OS" and then "Starting Fastboot USB download protocol".

I'm completely baffled. I've never had this much trouble loading a custom recovery before. It went fine on my HTC Hero, Galaxy S2 and Galaxy S4.

Thoughts?!

Thanks for the help!
[Transformer TF300T General] CatalystNZ:
I'm having a similar issue. I believe that my bootloader is NOT unlocked, even though the ASUS Unlock app says my device is unlocked.

If you run "fastboot -i 0x0b05 getvar all" you may see the following like me...

Like I said, every time I attempt to unlock the device from the Asus program, it tells me that the device is already unlocked. Which it is not.

I wanted to say thanks a bunch. This worked great. I've had android phones but just picked up a factory refurb TF300T. It already had Android 4.2.1 preloaded with the 10.6.1.27.5 bootloader.

I almost forgot to enable developer stuff (debugging, usb, 3rd party, etc.) but once I did, the guide worked perfect. Unlocked the bootloader, installed TWRP & then SuperSU.

Boom - rooted!

Thanks again. :D

[Transformer TF300T General] jgardner27:
use version 2.5.0.0

I can confirm this. I tried using the latest 2.6.3.0, and it failed to mount /boot and /recovery. Flashed 2.5 instead, no problems. Should've read ahead.
[Transformer TF300T General] JLine05:
Having issues, I fastbooted the Asus update and fastbooted the TWRP 2.5. I went into TWRP and installed the latest CROMI and it will not boot. I get the custom boot animation but it just sits on that screen.

I tried restoring my backup and it restores fine but will not boot up. I remember reading that installing the new Asus firmware will remove the USB option for fastboot, and that fastboot is just enabled by default when you go into the recovery. I have the opposite, fastboot was automatic before but now I have the USB option on the bootloader. Any help or ideas I could try would be appreciated.

HELP PLEASE

Here it goes, I have asus tf300t it was on 4.4.2 CMB Rom

with Philz CWM v6.0.4.5 recovery. This device is unlocked, says on boot.

Here is what I done:

I tried to go back to old rom CROMi-X 5.2.4, put the files on SD card:

recovery, rom…. I flashed recovery TWRP 2.6, restarted and boot went ok. After

that I went to recovery again,on start recovery, asked for password, I hit

cancel, wipe everything , that is probably mistake , when I tried to flash rom,

I couldn’t see SD card. I saw if forums that you don’t wipe everything trough bootloader, I did it from TWRP!!! Now

I’m stack on recovery, I can go to bootloader mode, or do anything with sd

card. Later I find that I could mount sdcard from recovery, from File manager

files on sdcard are shown in system dir, but only when I mount the system from

recovery, can’t mount anything else. I managed to copy files from there to SD

card dir, that is shown on File manager, I dont now where is that since I can’t

see them after reboot. Allways write a massage can mount a cache. Last night I

manage to go and flash rom from recovery, all went ok, when i did reboot , I’m

on recovery again !!! like I did do a thing !!! In file manager , on root of

device I can see files, also there is a supersu dir with : 99SuperSUDemon,

install-recovery.sh, su, Superuser.apk files in it.

Can anybody help me???

update: somehow I boot in bootloader menu.... in android 4.4.2 but, I couldn.t install any new recovery, on reboot it just went in twrp 2.6 again and again....
[Transformer TF300T General] sbdags:
Sounds like you flashed the wrong recovery. What boot loader are you on?

I wouldn't go above twrp 2.5.0.0 - get the one with 4.2 in the name and flash that first. Your recovery should be 10.6.1.27.1 or .5

Failing that use busters method to recovery your device.
[Transformer TF300T General] funnel71:

No recovery for TF300TG on 4.2.1. (yet?)

I have been searching this and other fora and it seems to be that there is no TWRP recovery yet available for a TF300TG on 4.2.1

Am I correct in that conclusion?

If so, does anybody know if a version is 'in the works' somewhere?

Or is there an alternative recovery available one can use?

I'm getting a bit blinded by info being spread out over multiple threads and fora.

My reason for asking is that my TG has a cracked screen and is on stock Rom. Repair seems possible but one needs to change some firmware. And to do that, I believe, one needs root and/or unlock. Doing that without recovery seems risky (understatement?)
[Transformer TF300T General] f69m:
The TF300T recoveries should work fine for TF300TG too. Just make sure to pick the right version for your bootloader and for the ROM you want to flash.

[Transformer TF300T General] Rytharr:
I just got a used tf300t and I have a couple questions before I do anything with it. ITs running 4.2.1 & 10.6.1.27.5. If I boot it with Volume Down held I get the screen with rck,android, and full wipe so does that mean that it is already unlocked? Can I just start from the installing TWRP step then install a custom rom?
[Transformer TF300T General] f69m:
If it is unlocked, the boot screen with the Asus logo will show "The Device is UnLocked" in the top-left corner. On the bootloader screen with the 3 icons in the middle you should see something like "Starting Fastboot Protocol" in the top-left corner under the long version number. If you see both, you are fine to go, otherwise you have to unlock first.

Go to the andro-wook page and download flumpster's twrp + bootloader package for 10.6.1.27.1

Flash it from recovery

Then you need to upgrade to the latest TWRP manually - which you will need to ask someone else for help as I'm not sure where you get one from but there is one available somewhere.

How to downgrade from 4.4.4 to 4.2

I'm using the rom CROMBi-KK-RC3: http://xdaforums.com/showthread.php?t=2686235

But I think it isn't as smooth as CROMi-X-5.4 (android 4.2, http://xdaforums.com/showthread.php?t=2686235 ) which I used to use before. In addition, I really love the old tablet UI with status-navigation combined bar instead of separate ones in KK.

So I want to downgrade back to 4.2 (with ASUS stock firmware 10.6.1.27.5 and TWRP 2.5.0.0) in order to fit CROMi-X's prerequisite.

Automatic update 4.1.1 to 4.2.1 doesn't work with TWRP installed. How to update?

I'm on 4.1.1 (unlocked, rooted) and the old Bootloader with 4 icons and TWRP 2.4.3.0.

I want to install the 4.2.1 (WW) from Asus and put it on the external microSD.

The ROM recognised it and I started automatic update, BUT

the procedure got stuck at my TWRP recovery. The automatic update only works with stock recovery.

Now I tried to install the Update ZIP in TWRP 2.4.3.0. It stopped with an error code.

Then I rebooted to system. An installation script 'optimized' 78 applications and I ended up in an unchanged 4.1.1 Stock ROM with nothing really changed.

I understand the difficulties of 4.1 Bootloader and Custom Recovery versus 4.2 Bootloader.

I installed TWRP 2.5.0.0 for JB and it works. fastboot und adb work too.

Question: How do I get from here (4.1.1 and TWRP 2.5.0.0-JB) to an 4.2.1 Stock ROM in a save way?

Problem: The automatic upgrade procedure works only with the stock 4.1 recovery not with TWRP recovery and I don't have an image of the 4.1 stock recovery which I could flash.

SOLVED:

I flashed the blob from the 4.2.1 Update to staging and rebooted. It did the update including installing the new 4.2 bootloader and 4.2 stock recovery. Therefore the TWRP 2.5.0.0-JB was gone. After that I installed TWRP 2.8.0.1-4.2 and entered recovery. It did suggest to install SuperSU and root the tablet again, which I did. Now I have 4.2.1.11 and TWRP 2.8.0.1-4.2, perfect.

I have just been given a TF300 to play with and manually installed the update zip, Version WW_V10.6.2.11 from Asus website.

New ROM, rooted, newest TWRP..

What i think it happened with mine, was regarding old twrp and i think the partition map.

when i started the flash, it gave some error about listing/mapping partition (don't recall), and then started to flash.. After sometime just outputted an error and that was it.

Couldn't pass Asus logo and got a boot loop. From what i understood form my search, my luck was having a new firmware (newest base), if I tried to recover with the same firmware base that I had, it would still be a paper weight.
