Yes I am and have the double screen

So should I go ahead with it?

I got that error while trying to flash Version WW_V10.6.1.15.3
[Transformer TF300T General] f69m:
Well, yes for the v10.6.1.8 bootloader this is the correct version.

Why must those version numbers be so long? :what:
[Transformer TF300T General] Noyankees44:
I am on cleanrom i

Can I use method 2 without first flashing stock rom? I am not sure what all this is rewriting.

I will be immediately updating to the twrp, and the new cleanrom, but I need to know if I am going to brick initially.

Sent from my SCH-I535
[Transformer TF300T General] f69m:
With cleanrom you still have the old 4.1 boot loader, right?

That is Asus version 10.4.* showing on the bootloader screen.

In that case you must flash stock first, to upgrade your bootloader and partition table.
[Transformer TF300T General] Noyankees44:
Yes and Ok.

I am assuming that the stock firmware is on asus's site? And I can flash it in fastboot?

Sent from my SCH-I535
[Transformer TF300T General] f69m:
Yes, on the Asus site or in the sticky thread that has all the ROM links.

How to flash it is surely well described in the first post?
[Transformer TF300T General] lazer9:
I am having no luck whatever I try. Getting a double screen. Can't flash anything with fastboot, I have to use adb shell with tablet booted and twrp.blob on sdcard internal. It says it completes but still stuck with 2.5.0.0 showing a double screen and no ability to do anything in recovery. Any more guesses on how to fix? Thanks
[Transformer TF300T General] mloc33:
I`m sorry but after reading this from the OP ...Since this new update brings a new bootloader, older recovery versions from 4.1 won't work at all. Don't try to flash one! I have`nt got a bloody clue what to do....

I know this is a big question but could you step by step tell me what to do, if not I`ll understand.
[Transformer TF300T General] f69m:
Well, as fastboot is not working, I guess using adb shell and dd is your only option.

Never used that myself, so all I can say is: you probably need to adb shell into recovery, as most ROMs will not let you dd to the flash partitions. Just some hints to go searching with, sorry.

---------- Post added at 10:38 PM ---------- Previous post was at 10:20 PM ----------

Sure!

First of all go to the bootloader screen by holding power and vol-down.

Double-check the Asus version of your bootloader at the top of the bootloader screen and pick the right TWRP version for it:

For Asus v10.4.*: any TWRP *-jb.blob

For Asus v10.6.1.8.*: only TWRP 2.4.4.0-4.2.blob

For Asus v10.6.1.15.*: any TWRP *-4.2.blob

Hope this is clear enough! ;)

Note that it does not matter, what you are going to flash. You need to pick the recovery based on the version of the bootloader currently installed, as it shows at the top of the screen.

Then enter fastboot mode in your bootloader:

For v10.4.* press vol-down repeatedly to select the USB icon, then vol-up once.

For v10.6.* fastboot is automatically started, once you see the bootloader screen.

Then make sure your tablet is connected to your PC with the USB cable.

On your PC run fastboot to flash and reboot:

fastboot -i 0x0B05 flash recovery twrp.blob
fastboot -i 0x0B05 reboot

On Linux try "sudo fastboot" instead of "fastboot" for both commands.

"twrp.blob" is of course the right file selected and downloaded according to the list above.

Hope this is not too verbose, but I guess it might help others too. :)
[Transformer TF300T General] mloc33:
I`m looking at the TWRP site but I don`t see the matching TWRP.

I`m on 10.6.1.8, going to try flashing 10.6.1.15

Edit: Scratch that I`m going to bed, I feel like if I do anymore I`ll really mess up my tab, start again tomorrow....fresh head, thanks man for your help, talk tomorrow.

Edit: Morning people, I`m looking for the TWRP 2.4.4.0-4.2.blob, not having much look.

I just want to confirm or make sure, that this is what I need to get my recovery back, this is what I have..

Edit: I came across this post and this one, looks promising, what do you think?

Just thinking of trying to flash TWRP 2.5.0.0 via the OP again and see if that works..?

Edit: Again I came across this looks like a fairly good option to try, at this stage I`ve seen so much options, I think I`m more confused, the more I search the more possibilities I find....sigh...
[Transformer TF300T General] mloc33:
Finally got TWRP working (2.4.4.0) was able to flash SU now onto CROMi, thanks again to people who helped me out, life savers. :)

I used this guide
[Transformer TF300T General] Hammerhand.17:
So, just to clarify. If I am in cromi 4.3:

1. Download and upgrade to official WW10.6.1.15.3 .

2. Install 2.5.0.0 TWRP

3. Install Cromi 4.4, based on 10.6.1.14.4 (or restore a TWRP backup)

Will TWRP work, or since I downgraded it will stop working?
[Transformer TF300T General] joelalmeidaptg:
It will work as you are saying. The porpoise on updating to the last Asus version doesn't have anything to do with the ROM itself and yes the bootloader. Since the new TWRP is only available for the last bootloader (and probably the next versions) you need to update your tablet, but you will still be able to use other 4.2 ROMs . You can restore your backup, it will work (note that the kernel will change for the stock one if you don't install the Rom selecting a custom kernel).
[Transformer TF300T General] Hammerhand.17:
Thanks a lot, this is what I wanted to now.

I have updated and, like the other time, now windows doesn't recognize the tablet as bootloader anymore (grrrr).

Gonna try to use vmware player again.
[Transformer TF300T General] joelalmeidaptg:
Your computer really does like to mock you xD I used my tablet on windows 7/8 64 and various linux distros and my tablet was always recognized
[Transformer TF300T General] Hammerhand.17:
Yeah I'm gonna throw it out the window :eek:

Don't know why, but no matter what computer I attach the tablet, it doesn't recognize it.
[Transformer TF300T General] slickdaddy96:
I had to go through three computers using the right drivers each time before one of my computers recognized and allowed flashing blob files. I used a USB 3.0 port which I don't know if it makes a difference or not.
[Transformer TF300T General] Rhian:
Ehm, maybe you just forgot to enable USB debugging after flashing the official 10.6.1.15.3? I know that tripped me up.
[Transformer TF300T General] Hammerhand.17:
No, it is enabled.

In linux, if I use "sudo fastboot devices" I

????????????
[Transformer TF300T General] Vinsane:
Now unlocked

Question after I press the power and vol down..I get the 3 options - RCK -Android - Wipe

Which do I select to run the fastboot/TWRP cmd? It's NOT showing a USB icon that I have seen others show?
[Transformer TF300T General] Rhian:
If there is no USB icon it means you're on JB 4.2.1 (or greater). There should be a small line saying "Starting Fastboot USB download protocol". When that has appeared, fastboot is available.

Once you flashed TWRP, you can use the volume up button on RCK (Recovery). (Volume down to scroll through the options).
[Transformer TF300T General] Vinsane:
Think I got it this time..had to redo it....lets give it a go!
[Transformer TF300T General] Rhian:
On your PC type fastboot devices to get a list of connected devices with fastboot enabled. (Normally one.) If it sees your pad, it displays your serial number in hexadecimal code. Once you can communicate with your device you'll be able to flash. A normal flashing looks a little like this:

E:\>fastboot devices
015xxxxxxx fastboot

E:\>fastboot flash recovery openrecovery-twrp-2.5.0.0-tf300t-4.2.blob
sending 'recovery' (6448 KB)...
OKAY [ 1.238s]
writing 'recovery'...
OKAY [ 1.264s]
finished. total time: 2.506s

E:\>fastboot reboot-bootloader
rebooting into bootloader...
OKAY [ 0.021s]
finished. total time: 0.022s

After that you can go into the RCK (Recovery)
[Transformer TF300T General] Vinsane:

Imwanting to DOWNGRADE to BL 4.2.1 from 4.2.2 so i can install custom overclocked ROMs, these on 4.2.2 BL are not cutting it without the overclock. I dont feel like waiting for the source to release for the newest BL so i want to downgrade. I had seen somewhere someone was saying switching back and forth between BL's is really easy and just have to do it through fastboot. Can anyone confirm?
[Transformer TF300T General] Rhian:
Flashing one or the other TWRP for the wrong FW is not advisable at all. I strongly recommend downgrading your FW to the corresponding one for TWRP before flashing.

I assume that's what you mean by BL? If you mean the OS JB, sort of the same applies. You can try using one of the official FWs from Asus directly (as a regular up/downgrade) or use this method: [HOW-TO] Upgrade or Downgrade to any stock JB Firmware

FW 10.6.15.3 works fine with Surdu's OC kernels: [3 IN 1][ROM-THEME-KERNEL up to 1.8GHz][Stock Asus Firmware 10.6.1.15.3]

I hope this helps.

I'm a bit desperate here. I'm running 4.2.1 latest build and I tried multiple flavors of TWRP (running 2.5.0.0 right now) and CWM. All of them fail to mount EVERYTHING including SD Card. What can I do? Fastboot and Android work fine but recovery is useless.... nothing you listed worked. Please! I NEEDS ROOTS OMNOMSNOMS :D
[Transformer TF300T General] f69m:
Did you try any of the -4.2.blob flavours?

That's the only ones the 4.2 boot loader will eat.
[Transformer TF300T General] GrippenTech:
Not for TWRP, I guess I'll try that. Also, I have to run the normal/non touch since they just seem to work better/faster for me. I'll keep you posted as to if it works or not...
[Transformer TF300T General] maximus20895:
When I upgrade the TWRP to 2.5.0.0 it is split into two mirrors and the recovery doesn't look like it should. I have tried it a few times. Any ideas on what I should do?

EDIT: the link in the first post for 2.5.0.0 was around 6.x mb which didn't work for me while the teamwin site for the same recovery was 7.x mb and worked.
[Transformer TF300T General] Rhian:
Did you check you have the right TWRP for your FW version? Picking the wrong one does have the double screen effect or inability to mount filesystems.
[Transformer TF300T General] maximus20895:
Hmm, I don't know. I tried one and it did the double screen and now the one I thought worked wouldn't delete anything and said it couldn't mount something so I don't know what one I need.

I'm on jb v10.6.1.8 right now with cromi 4.3 installed. I want to go to cromi 4.5 so now I'm really confused what to do because I thought you had to be on 2.5.0.0 in order to install the latest asus firmware and then install cromi 4.5.

Any help :(
[Transformer TF300T General] Rhian:
You don't have to be on TWRP 2.5.

You either:

-> move to FW 10.6.1.15.3 AND TWRP 2.5.0.0-4.2

OR

-> stay on the FW 10.6.1.8 and flash the TWRP 2.4.4.0-4.2.blob.

You can't combine 10.6.1.8 with 2.5, it just doesn't work.

From CROMi-X thread:

Again you see the choices... :)
[Transformer TF300T General] maximus20895:
But don't you have to be on 2.5 if you want to be on the FW 10.6.1.15.3?

If that is the case how do you flash 10.6.1.15.3? Can you flash it with twrp 2.4.4? If not then that means you have to flash 10.6.1.15.3 with 2.5, but you can't have the 2.5 twrp with 10.6.1.8.

Does that make any sense what so ever?
[Transformer TF300T General] funnel71:
The key is to choose the tarp that matches your android version. If you're on 4.1, choose the twrp file with jb in the name. If on 4.2, like build 10.6.1.15.3 is, you need the twrp file with 4.2 in the name. Both 2.4.4.0 and 2.5.0.0 have both variants.

FYI, both 10.6.1.8 and 10.6.1.15.3 are android 4.2 builds so either version of twrp with 4.2 in the file name should work. I use 2.5.0.0 because in that version, they fixed the ability to read from the external SD card, at least my card anyway.
[Transformer TF300T General] maximus20895:
I don't get it. I have 10.6.1.8 which is android 4.2.1 and I tried to use twrp 2.5.0.0-4.2 and it still does the mirroring. wtf..

Edit: Okay so I downloaded 2.4.4.0 twrp 4.2 and it seems to work. Can I flash the newest firmware which is 10.6.1.15.3 with 2.4.4.0 or do I have to be on 2.5.0.0?

If I have to be on 2.5.0.0 I don't know how it's going to work since none of them seem to work for me while I am on 10.6.1.8.

Thanks.
[Transformer TF300T General] funnel71:
You'll have to reflash recovery after you flash the ROM anyway, so give 2.5 another shot. I'm using it now with the latest ROM, and its working fine.
[Transformer TF300T General] maximus20895:
I've tried 2.5 numberous times. Right now I am installing 10.6.1.15.3 with fastboot and the 2.4.4.4 twrp. I hope that's okay.

Then I will install 2.5 and then I will install cromi 4.5.

Does that seem right?
[Transformer TF300T General] funnel71:
I'm not familiar with cromi sorry.
[Transformer TF300T General] stewa2jm:
I've read a lot of this thread and still haven't found my answer. Please forgive me if I missed it. Here is my issue.

First off, I'm using a 13.04 Ubunut machine. ADB and FASTBOOT are installed and working normally on other devices.

The TF300T is on the latest update 4.2 - 10.6.1.15.3 US version

I can use ADB to reboot into bootloader from the main screen on the TF300T.

When in the "bootloader" it reads:

Key Driver not found.. Booting os
Android cardhu-user bootloader <1.00 e> released by "US_epad-10.6.1.15.3-20130416" A03

Starting Fastboot USB download protocol

and then shows the three icons (RCK) (ANDROID) (WIPE DATA)

From what I understand this is normal.

When I try to flash the recovery I get < wating for devices > and no other response.

I've found several threads where people found workaround or realized their own mistake and nothing has worked for me. I'd like to get this damn thing rooted and CM10 running. Any advice/help is greatly appreciated.

Refer to post #390 - use "sudo fastboot"

Thanks f69m
[Transformer TF300T General] maximus20895:
Maybe you don't have the right driver or something. Doesn't look like your pc can see the tablet.
[Transformer TF300T General] stewa2jm:
Found the answer, FINALLY!! Use "sudo fastboot" command for Linux.
[Transformer TF300T General] stewa2jm:
Soft-Bricked

In my excitement and fatigue I didn't back-up my system before flashing CM10... now I'm soft-bricked. I can get into TWRP (Poor choice as I much prefer CWM), but when I attempt to boot CM i'm stuck at the ASUS boot screen with "The Device is Unlocked" in the corner. TWRP won't mount for me to drop a different version of CM to try and flash, so I'm at a loss.

Can anyone send me in the right direction? And I don't need a lecture on not backing up my system, I realize the boneheadedness in this... I got distracted by the 5 hours I spent trying to get this damn thing rooted.

I got it back to stock JB 4.2. Thank you insomnia for the help. I'll proceed with root on the morrow.

[Transformer TF300T General] f69m:
TWRP 2.5.0.0-4.2 does not work with the older 4.2 bootloader v10.6.1.8.*

This combination has the split or double screen issue.

If you want to use TWRP 2.5.0.0-4.2, make sure you have upgraded to the latest bootloader v10.6.1.15.3.

The safe way to check your current bootloader version is to look at the long version number at the top of the bootloader screen. I don't recommend guessing the bootloader version from your current ROM; check the real thing!

Unable to mount anything but system using CWM or TWRP

Does anyone know if the update changed the file system??? I updated using fastboot and then accidentally hit RCK after a reboot. They device showed the android recovery and after a while rebooted. It had erased all the memory and now I have a clean device running the latest rom from Asus.

However, now having installed both TWRP 2.5.0.0 and CWM 6.0.2.3, neither can mount any partition except system.

Has Anyone seen this, and is there a fix?

THANKS

Amazingly, if I mount system under TWRP - I see the root of the internal sdcard. And can flash whatever i want.

BUT why can't I mount anything else????
[Transformer TF300T General] JoelParke:
Update... to unable to mount

I mistakenly thought I could flash whatever. Not the case...

When I mount system, I do see an older zip file that I can flash, but I can't ever see the internal sd, or the microSD.

If I can't resolve this, I will need to fastboot a new rom.

Does anyone have a recommendation for one that has a blob file that I can fastboot? Thanks.
[Transformer TF300T General] ricco333:
Did you install twrp 2.5.0.0-4.2? That's the only recovery that works with the 4.2 bootloader.

The update guide works if you follow instructions and use the provided files, I updated using fastboot and everything went smooth.
