[Transformer TF300T General] funnel71:
I found 2.6 was not handling things correctly like backups, so I went back to 2.5.0.0. I never had the password issue. That has happened to those that installed the 4-2 build on 4.1 firmware. Not sure if that's what you did but I'm finding 2.5.0.0-4.2 works best for me, running the latest Asus build.

Updated the guide with the following changes:

Removed the fastboot reboot command that doesn't work

Changed the info about TWRP 2.5.0.0 to the new version 2.6.0.0 .

The issues of the last TWRP 2.6.0.0 not backing up to an external SD card seem to be fixed on the latest bootloader V10.6.1.27.1 from Asus. Tested it myself.

[Transformer TF300T General] robgee789:
Are there any bugs in 2.6.0.0 ?
[Transformer TF300T General] joelalmeidaptg:
I don't think so,at least I haven't had any problem until now. The major issue with the older bootloader was backing up for a external SD card, and I can confirm that it is working properly

I had this problem early-on (4+ months ago) and it turned out to be the USB port I was attempting to use. I switched from a front port to a rear one and it has worked flawlessly through numerous updates.

The USB cable can also give this error.

I updated the guide to revert to TWRP 2.5.0.0 . On the new bootloader 2.6.0.0 backups worked for the external SD card, but boot and recovery partitions weren't mounted and sometimes even without the check-boxes TWRP tried to backup them (you have to do a trick do make it only backup system and data - uncheck all boxes and check them again), and for that reason I downgraded here in the guide. Until next time :cyclops:

I dont know if someone cares but I just flashed stock asus fw 4.2.1 (that brings new bootloader) using CWM 6.0.2.3 (I was on cm10.1 with older bootloader)

So it is not necessary to start from twrp 2.5
[Transformer TF300T General] Spinergy02:
I had a completely stock locked system with that update and installed cwm 6.0.2.3 to begin with and had all sorts of problems. For beginners none of the partitions were showing up and when I tried to flash twrp 2.6.0.0 through fastboot the bootloader would freeze. I had to flash tarp 2.5.0.0 then 2.6.0.0. Just wanted to put that out there since there may be problems with trying to go directly to cwm from a completely stock system.

I can't install TWRP recovery

I am running the latest Android 4.2.1 (10.6.1.27.1) on my TF300T and I can not install TWRP. I read all the steps carefully and copied every single letter that was required for the command. I kept on getting the FAILED Command Write Failed (Unknown error) message every single time I inputted the "fastboot -i 0x0b05 flash recovery twrp.blob" command to Fastboot. I changed my USB ports around and I made sure they are USB 2.0 ports. I restarted my computer numerous times but that doesn't seem to solve the problem. I am trying to install Cromi-X but I did not install a recovery yet. I was able to downgrade this tablet to 4.1, root it, and install TWRP. Turns out Cromi-X froze on the boot-up animation so I reinstalled 4.2. Please help me with this. Thanks.
[Transformer TF300T General] funnel71:
For those getting an invalid state error, that normally means your bootloader is locked. I can't speak for any memo device, but that is true for the tf300.
[Transformer TF300T General] ruff97:
ok do i have to use Asus software "Unlock Device App: Unlock boot loader". to lockup my bootloader to install TWRP

Hi all I got Asus memo pad smart 10 ME301T unrooted and stock Asus latest firmware JOPD0D.WW-epad.10.6.1.29.20130710

Which exact guide I can use to use to root and install custom recovery ?

Which devices ROM are compatible with my device?

Thanks
[Transformer TF300T General] sbdags:
I've compiled my rom - CROMi-X to be compatible. Roms need specific kernel files as wellas libs and modules inserted so that your device will work 100%. The closest device is the TF300T.

confused

Hey hey, So I knew how to update and all, Im using Cromi-x 4.7 for few months now. But im on the 10.6.1.15.3.

And I was wondering, if I download the official rom and install it via TWRP (so putting it on the sd card and installing it with TWRP as a custom rom...as usually you need to update the Cromi-x) will it update my bootloader to 10.6.1.27.1? and do I have to flash TWRP after that with fastboot??

I did this once reading tons of guides and all when updating to10.6.1.15.3, but that was almost half an year ago and now I cant remember the procedure.

Sry for the incovinience and all, a simple no-yes answer will suffice

edit:I mean, does the 10.6.1.27.1 update change the bootloader again compared to 10.6.1.15.3 ?(as we know it was a pain doing the 10.6.1.15.3 update as it drasticaly changed the bootloader compared to the older version 10.6.1.8 (I think)....at least thats how I remember things)

TWRP can't find or mount partitions

I've unlocked my TF300t and

installed TWRP 2.5.0.0. When I

hold down the volume down and power keys to enter TWRP, it shows a screen and asks to Please Enter Your Password. I have no password and guessing common default passwords did nothing to help, so I

cancelled through the password screen. When

attempting to backup, and then clicking on the "Storage: Internal Storage," it shows I have 0MB internal storage (appears to be

not mounting internal partition) and no micro SD card (I actually have a 64gb card in the micro sd slot). I've

attempted installing TWRP 2.6, 2.6.1, 2.5, and 2.4,

returning back to TWRP 2.5. When I

attempt to shutdown/reboot, the top of the screen says,

"No OS"

I don't want to proceed to root my TF300T without completing a backup (and actually, even if I wanted to, I can't proceed because I can't flash the superuser app without a mounted partition).

Can someone please assist?

easy, just get to fastboot. and use the first command that i have put..

" fastboot -i 0x0B05 flash system blob"

the blob file is inside the zip.... the blob file needs to be where your fastboot/adb can detect it..

[Transformer TF300T General] avatar_pt:
my "friend", it was bricked! as per other threads, beeing on a boot loop is a soft brick... my luck was that there was a newer firmware than the one there was on the tablet.

there is no point on arguing about this... comparing to a Router, you can brick it till it stinks like a cadaver and yet revive it again, but I guess that is too much to process and highly off topic.

First no one was "screaming".. my only concern was that if it happened with me, it might happen with others, just that.

This is a community, the mojo is to help others.. If there was something wrong, following a really SIMPLE set of instructions, it might happen again.. I'm usually a lurker, I've replied to the thread to prevent others from having the same fate.

If this is wrong.. well, i'll continue to lurk, at least I'll read about others misfortune , and simply wont care.
[Transformer TF300T General] nick1313:
Calm down my "friend". Not sure why you put that in quotes and I'm not arguing with you about anything because that's silly. If you truly bricked it, you wouldn't be using it but that's all semantics and how each of us see it as a brick. I see a device a brick that doesn't come back from the dead, meaning you must send it in to manufacturer or what have you, obviously you don't.

I'm trying to help, since that's the "mojo" of the community which I agree with, but obviously you aren't interested in that so I'll just move on.
[Transformer TF300T General] avatar_pt:
I was and am very calm... I just reported my "glitch" (so that there aren't any semantic issues), and people just contributed to the thread by telling to shut up, or the "you're doing it wrong".

I'm glad that you play the role of telling others to calm down or debating that people are not interested to help, it just shows that you need to win every keyboard battle.

I'll end this by just apologizing the OP, for having all this off topic. I'm glad that the OP opened the thread and provided instructions for others to follow. I'm also glad that it works for many, I just don't like not to know why it hasn't worked for me and at least another user.

In the end, mine is working and that is what it matters.

Kudos for everone :highfive:

Confirm that your version of twrp matches which android version you have installed.

4.1.x = twrp with jb in the file name.

4.2.x = twrp with 4-2 in the name.

Mixing these up can cause a brick. Be careful.

That's one of the threads I followed--which is why I started with, then ended up back on TWRP v. 2.5.0.0 (it appeared to be the most stable version based on the threads).

The problem I'm running into is that I can't proceed to Root my tf300t because the TWRP doesn't appear to have been installed completely/accurately. The instructions after installing TWRP on that thread say:

[BOTH BL] -- Rooting --

- Unlocked devices

Download SuperSu zip file from here and place it on a SD card or inside the root of your tablet's internal memory

Reboot the tablet holding vol down, and when the three icons appear, hit volume up to enter recovery

When the recovery prompts you a password, hit cancel (this is a bug from the current version of TWRP, and it should be fixed soon. It is ok to ignore it!)

Flash the zip you just downloaded

Wipe Dalvik/Cache (just in case)

Reboot

You are now rooted!

Step 4 is where I'm running into problems. I cannot flash anything because it doesn't recognize my internal OR external drives. I'm not going to wipe anything unless I can make a backup because the last thing I want to do is brick the tablet. I'm really at a loss here as to how to mount the partitions and thus, be able to gain Root access.

Thanks for the help/suggestions thus far though.

[Transformer TF300T General] funnel71:
Are you sure you installed 4.2.1 with fastboot? Normally, an invalidState means that your bootloader is locked, and that's why you can't flash recovery. Restart your tablet, and when you see the ASUS logo, look to the upper-left for the message "device is unlocked" - if you don't see that, then you're locked, and that's why you're getting that error.

To unlock, download the unlock APK from asus web site.

Hi mate, just a recommendation, for flashing the whole blob you should use this:

fastboot -i 0x0B05 flash staging blob

instead off

fastboot -i 0x0B05 flash system blob

it's should be safer because it's using the staging partition to send the blob. ;)
