Hello there,
I have a tf300t that was on stock with unlocked bootloader and with twrp 2.5.0.0.
After being fed up by the continuous lags of my tablet, I decided to perform a factory reset and so I did.
Big mistake... The tablet got stuck in boot loop and I had no choice but to flash with the latest 4.3.1 stable cyanogenmod rom (10.2.1-tf300t).
This step went well and, very proud of myself for saving my tablet, I have made another mistake... I wiped everything.
Now:
I have no recovery on my tablet.
I have a tablet that crashes far too often.
I'm pissed with myself.
I would like to restore my tf300t to the latest stock ROM.
As you have understood I am a newbie.
I don't know which stock ROM I have to download.
My build number is: cm_tf300t-userdebug 4.3.1 JLS36l 80ef19409a test-keys (WTF!!!)
My kernel version is: 3.1.10-g081 d5ba [email protected] # 1
Please help me find out which stock ROM I have to download.!:crying:

When you start up the tablet and press vol down, it shows which bootloader you have currently.
In most cases, you should flash the latest bootloader available on the Index in the Dev Section.
Tanks for your help. When it boots while pressing the vol down, it says exactly this message:
key driver not found .. Booting OS
Android cardhu-user bootloader <1.00 e> released by "ww_epad-10.6.1.27.5-20130902" A03
Starting fastboot USB download protocol.
I have downloaded from the Asus website the ww version of the firmware.
Do I just need to flash the tablet with the .zip or should I do something before?
Up.
Thanks.

I finally found the solution for my TF300t.
I wiped everything using TWRP and then installed the stock rom. using the zip file found on the Asus support website.

I have a asus tf300t running 4.2.1 with unlocked bootloader and root. I am running twrp v2.5.0.0 and I have already made backups of my apps. I am trying to install a custom rom. Preferably PACman rom but at this point any will do. When I try to flash the rom it go through the whole process then reboots but does not get past the asus splash screen.
What is the problem? Is it that the new bootloader does not accept any custom roms, if so how do I downgrade to 4.1? Otherwise I am open to any advice.

You must be on Jelly Bean 4.2.1
with the Asus Stock bootloader 10.6.1.8 and TWRP Recovery patched 2.4.4.0
or
Bootloader 10.1.15.3 and TWRP patched 2.5.0.0
You will find all versions of Stock firmwares and Stock kernels here
And the TWRP recoveries here

I am currently running the 10.1.15.3 bootloader and TWRP 2.5.0.0, yet it still does not finish flashing the ROM. I even tried to flash a more simple stock based ROM, ie. black beans 8. This did not work either. It went through the twrp flash and restarted but when it got to the ASUS boot up screen it simply stopped. I waited about 10 minutes for it to possibly load however it never did. So I am restored back to my stock and am awaiting any further help.

In the OP for PACman rom it says you must be on android 4.1.1 to flash his rom. You need to pick a rom for your 4.2.1. I am also on 4.2.1 and run CROMI 4.6.6 with no issues. Have also succesfully tried the Energy rom. Read carefully the OP for the rom's you are considering and make sure they are for 4.2.1

I am having the same problem! I am running 4.2.1 and im trying to install blackbean 8 using twrp 2.5.0.0. I factory reset in twrp and wipe cache and dalvic. I then install the the rom and reboot but it will not go past the first boot screen with the tegra logo in the bottom right. It always flashes for a second but then does nothing. I have even tried cm 10.1 and it does the exact same thing. I am still able to restore back to stock. This is my first time flashing a rom so any help would be appreciated!
For the latest [ROM][4.2.2][ OFFICIAL] PAC-man v23.0.0 [OC up to 1.7GHz][New Update 22/06/2013], if you read the installation process, you need to be 4.1.1 and not 4.2.1 and also you need installed custom recovery for JB 4.1 BL !
For the latest [ROM]ASU-JellyBean-Hydro 8 (6/29/13)Liquid Butter..- Tf300 -Official 10.6.1.15.3 Base, you need to be on 4.2.1 and 10.6.15.3 bootloader
and you will see to the changelog:
...not sure if any bootloader will work...

Hello,
After a couple of months on cm10.1 on my TF300T 32GB, I wanted to try another rom. I was (and still am) on TWRP v2.2.1.5, and after flashing a new rom (I think it was grimlock) it booted, but would crash after a minute or so of not doing anything. Deciding to flash another rom, I flashed paranoid android and it would never boot anymore. So that is my problem, I am completely stuck, and because I can't boot into android anymore, I can't place any files on my internal SD card to flash.
Is my TF300T beyond repair? Will I have to send it back? I also need some explanation on how Bootloaders/Recoveries/ROMS work on the TF300T, because it's really easy on my Galaxy Nexus but here it's all complicated.
EDIT:
It's also worth mentioning that when starting the tablet while powered off with the onbutton+volumedown it will say that the following bootloader is installed:
"WW_epad-10.4.2.13-20120907" a03
Your tab is not bricked but you are going to need micro sd or mount internal memory via twrp to put roms on your tablet
Sent from my HTC Desire C using xda app-developers app
While as above your tablet isn't bricked, flash the latest version of twrp with fastboot, "fastboot flash recovery *name-of-file*" then move a 4.1 compatible rom over to your tf300 and flash it (id suggest the latest stock firmware from Asus but its up to you)
Its pretty easy on the tf300t, but Asus in their infinite misguided wisdom decided to release a new bootloader with their 4.2 firmware that wasn't compatible with kernels built on prior sources, So now we just have to check if the rom/kernel you are flashing is compatible with the bootloader you're on, 10.4.x.xx is the old bootloader and 10.6.x.xx is the new bootloader, (devs call these bootloaders 4.1 and 4.2 bootloaders because of the versions of android they were released with, the bootloaders themselves are capable of running either 4.1 or 4.2 versions of android.)
Twrp is a recovery and a recovery is a kernel, so if you flash a version of twrp that isn't compatible with your bootloader version, it will not function correctly. Plenty of thread that should point you to the right version.

Thank you both. I will try to fix it with the instructions. I am really happy that I don't have to send my tablet for repairs. :fingers-crossed:
I have been on CM 10.1 for sometime but now cannot get anything past the July 6th nightly to boot. Are new CM revisiions only for the 4.2 bootloader?
Hey guys, so I unlocked and rooted my brothers TF300t last year, and now I'm having problems updating to the latest version of CM10.1. His tablet is currently on bootloader version 10.4.2.9 and CM10.1 20130612, and when I try to install the latest version of CM10.1 nightlies, the tablet just hangs on the Asus logo. (It's xplodwild's ROM) I'm running CWM 6.0.1.3 on his tablet. I thought I'd ask the great minds of XDA so that I'm completely sure I'm not going to brick my brothers tablet, because I can't afford to buy him a new one if I ruin this one. Plus I'd look like a complete retard :highfive:
So what am I doing wrong? I used to flash ROM's all the time on my old HTC phone, and I don't remember having to worry about my bootloader version much. Do I need to upgrade to a newer bootloader version? Is my recovery out of date? I've tried doing a full wipe and installing the latest ROM as well as installing over top his current version, and nothing works, it just hangs at the Asus logo.
If any further clarifications are needed, please let me know. I appreciate any and all help! Thanks.

for the latest cm10.1 you need the latest 4.2 bootloader that u can get it by flashing the latest asus stock rom...
This http://forum.xda-developers.com/showthread.php?t=2187982 is a guide how to install the latest 4.2.1 version of Asus that also contains the latest 4.2 bootloader
You have many methods how to do it, so chose what seems easier to you
After u do this u can flash whatever 4.2 bootloader rom
My TF300T still has the old stock firmware from October 2012 (4.1).
It is unlocked and has TWRP from february 2013.
Now I will be jumping to a current custom firmware (Crombi-kk 4.4).
If I understand correctly, I have to flash the latest STOCK firmware (V10.6.1.27.5 android 4.2) and install the new CWM/TWRP before I can flash a custom firmware.
My main worry is flashing the newest stock rom on my already TWRP/rooted/unlocked TF300T. Will that cause a problem or will the stock firmware wipe everything clean (except for the unlock)?
Also, the unlock utility on Asus's website is made for 4.2 only. When I unlocked my TF300T, it was 4.1. What will happen when I flash the stock 4.2? Will my 4.1 unlock cause problems or will it be wiped, or will it still be effective?

Thanks for your offer. I actually got the green light on the CM 4.4.x Q&A thread.
I read that flashing the CWM for 4.1 would brick your tablet if you had 4.2 installed, so I was worried that flashing 4.2 on top of an existing 4.1 CWM would brick it as well. It turns out it simply removes the CWM entirely. Good times.
Basically what I ended up doing was:
1 - Transfer the latest official TF300T firmware (zip file) onto an SD card.
2 - Start my TF300T with my old (4.1) CWM recovery and select to flash my android with the zip file on the SD card.
3 - The TF300T bootloader stayed unlocked, but the old CWM was gone.
4 - Using ADB: Upload & flash the new CWM Philz Touch
5 - Install/flash the desired custom rom (from within CWM using SD card)
6 - Restore to factory default (from within CWM)
Now I even installed Grimlock's kernel to allow overclocking.
My TF300T has a new life. It is now very much acceptable in terms of speed.
I recently bought a TF300t second hand and I really need some help! Some years back I was playing around with custom roms on Android devices but im very out of touch.
I would like to install one of the more recent roms on this device. Any suggestion here appreciated.
The device has already been rooted and has TWRP v2.6.3.1 installed. I understand that I need to upgrade this to 2.8. to install the latest roms but im having issues doing that. For a start im unsure how to find out if I have the latest Bootloader 4.2
I really dont want to brick this device!
I tried using ADB to update TWRP but the usb connection never seemed to find my device in the right mode.
The device is currently running Android 4.2.1
Custom ROM CROMi-Xenogenesis 5.4 - 10.6.127.5 WW ODEX.
Any help and advice really appreciated )

Android 4.2.1 is newest official.
10.6..... is bootloader version - newest there is.
flashing recovery and/or ROM will not overwrite bootloader - it stays the same.
You can go to twrp official website and get 2.8.0.1-4.2 blob to flash (unless your target rom states different version needed - see 1st post of yout target thread) - I got it from there - flashed KatKiss using it.
ADB - when android is running.
fastboot - on bootloader screen (booted with voldown+power - RCK / android / wipe data icons) - used to flash twrp blob

Ok got it all fixed now. Thanks!
So, not to hijack, but I'm actually in a similar boat. I'm currently rooted and unlocked on 4.1.1 TWRP 2.3.3.0 and am looking to flash the new 5.0 Rom.
Does anyone have a handy guide on what I should do? Do I just need to flash a 4.4 compatible TWRP version, then flash the ROM? Would like to avoid bricking my tablet.

Yes here you are ....
Get the SKU from your bootloader screen .....
Then go to the Asus website and get the firmware for your SKU ending in 27.5 ...
Then unpack the zip and there will be another zip unzip it you will find a file called blob ....
Flash this blob from fastboot ...
Thx Josh
