Bricked my tf300t? - Transformer TF300T Q&A, Help & Troubleshooting

To sum everything up:
1. My rom didn't work so I decided to find a new one :good:
2. I read and understand that it's much easier using fastboot
3. I was flashing the official rom when the antivirus requested a reboot
4. I forgot the flashing, and just clicked on reboot :silly: :crying:
The screen remains black when I try to boot it up :crying:
The only sign of life is when I'm charging the light is lighting and "APX" is showing in the device manager on pc with a yellow triangle, I haven't understand what "APX" stand for yet so please explain
(My bootloader was unlocked and I flashed twrp 2.5.5 just before I did this)
Do you have any tips for me? Or is the device bricked and have to be sent for service?
Please help me :fingers-crossed:
Edit: This is wrong section I know, can anyone move it to the Q&A please?

Moved.

Apx is a method provided by the cpu manufacture for recovery. Due to the way asus has handled locking the unit apx is only available if nvflash is installed while on ICS (4.0).
Reset may be a good option for you. Power on unit. Hold volume down and insert a small paperclip to into into the reset hole. This may get you into the bootloader.
Reset: A small hole about 25mm or 1inch below the sdcard slot.
Note: If this fails you could do the same but hold volume up and hope.
Beyond this running the battery down has worked for some or remove the back cover and disconnect the battery. Leave it disconnected for thirty minutes, then reconnect.
Also see my signature for other methods to get into the bootloader. Don't bother with apx as it is useless for us.
We are looking for any change in the unit. With a change may come use of adb, fastboot, or recovery.
Try do each thing in turn and repeat this sequence twice more.

Thanks for the explanation and fir the tips! I'm going to try this

It doesn't seem that any of the following work, but I haven't tried the battery pull thing, because I see that it's a sticker over the cover that says that the warrenty is void if removed. If I send it for service will the guys know that I have unlocked it, and then void the warranty?

I understand. If still in warranty I wouldn't remove it either.
I'm sorry that is all I have for your situation.

Lads, let me join your conversation. I've almost same problem, probably different root cause, but same summary:
1. Originally I downloaded JB 4.2 from support.asus.com source
2. Tablet got reflashed & worked as normal, but I lost roots which I had earlier, therefore I decided to get root privs again.
3. So, I went into TWRP web-site & downloaded openrecovery-twrp-2.5.0.0-tf300tg-JB.blob blob file & via ADB was able to flash TWRP 2.5 onto my TF300T, but...
4. ...somehow TWRP doesn't let me to mount neither system, not SD-card, nothing. And currently
5. I think I'm bricked (& my TF300T too). When I press power button - tablet switches on & gets straight into TWRP, where I've only option to power it down or reboot TWRP tells me "are you sure? No OS installed".
6. When I try to switch tablet into bootload (with volume -) writing "The Device is Unlocked" shortly blinks slightly brighter, kind of trying to get into bootloader, but gets into TWRP anyway.
Any help, please! I know how Donate button works!
P.S. Because I very new writer (but really old reader) of XDA - I can't incert outside links...

Which tablet do you have? You show TF300T but using TF300TG twrp.
The bootloader changed again with 4.2 firmware and requires twrp especially for that version. I have been told the openrecovery-twrp-2.5.0.0-tf300t-4.2.blob does not work properly so you should have used openrecovery-twrp-2.4.4.0-tf300t-4.2.blob if you have a tf300t.
We need to break the cycle of going into twrp and only twrp.
Let's try to use twrp for that purpose. While in twrp select reboot while holding volume down.
If that fails to make a change while in twrp type adb reboot bootloader.
If that makes no change type fastboot -i 0x0B05 reboot-bootloader.
If there is still no change try the reset while holding volume down.
Reset: A small hole about 25mm or 1inch below the sdcard slot. Use a small paperclip to insert into the hole and press gently while holding volume down.

Dear Friend! :good: That what makes difference between you - old member & me - amatuer. Yes, I loaded ...TG version of TWRP onto my ..T tablet. Bad words aren't allowed in XDA forum, otherwise I'd call myself with proper name. Anyway,
I tried to reboot from TWRP, held volume - & had no success. It loaded into TWRP again.
Then tried to reboot with command adb reboot bootloader, as you mentioned - my Windows7 PC doesn't see tablet, showing Transformer with yellow ! sign. And I tried fastboot -i 0x0B05 reboot-bootloader command, ADB is saying <waiting for device> forever & nothing happens. so I stopped here so far, waiting for your advise...

No bad words needed. We all make mistakes. I them pointed out for future reference in case you were not aware.
First you need to get your drivers loaded for windows.

Ok...
So, I bricked my tf300t. I ordered a new motherboard off ebay and replaced the bricked one. It works, but it was not factory reset and still has the owners info, etc. It is password protected. I don't know the pw. When I try to boot into the recovery console, I get a dead android. Going into the menu, I have an option to wipe or boot android. How do I get around this?

My suggestion is use stock recovery to replace the encrypted os (probably JB 4.2) with JB 4.1 (10.4.2.20). You can download here [INDEX]25 Apr 2013 - TF300T/TG WITH ALL ASUS ORIGINAL TOOLS-Firmwares-Kernels-Guides-. Look in firmware TF300T. Use the proper sku (ww, us, etc) for your country. Please give philos64 a thanks while there he spent much time creating that post, supporting the downloads, and updating.
Unzip the downloaded file once - rename to EP201_768_SDUPDATE.zip. Place the file on your internal sdcard if possible if not place on your micro sdcard. Boot into the recovery console and make the hungry android happy. This will probably take ten plus minutes.

Dear tobdaryl! Thanks very much for your advice, I had to dissapear for couple of days, so couldn't answer. I followed your link & had no success. When I power on TF300T & connect it to PC, it's being read as Transformer (see my 1st picture), unlike in the guide they are working with Asus Eee pad device (my 2nd picture), so when I'm trying to install drivers from un-zipped folder it says "...couldn't install drivers for your Transformer".
Looking for more help... (

Right click on the Transformer with the yellow symbol and point to your Universal Naked Drivers inf file. If one inf files fails to install then try the other.

Tobdaryl, I couldn't find "Donate Me" button in your profile, so give me your paypal account for a little present please! :good: It worked!!! I installed correct driver from given guide, rebooted into bootloader, using ADB comand & got 3 icons: RCK, Android & Wipe Data. I tried Wipe Data, it said "can't mount something", don't remember now what. I rebooted again & clicked on Android & loaded into normal screen. Because of Asus became completely flat I put it on charge now. And after that I will have to come back to original task - to root my TF300T. While it's charging I downloaded Goo manager & tried to install TWRP, it said "No recoveries were found for your device", but in same time file for my device (that's where I made mistake, downloading TF300TG version) does exist, so what's story here? I guess this is may be because my TF300T isn't rooted yet?
Adding later. after digging this & other forums I found that in order to get root & have to have CWM/TWRP on my device & I can't get them until my TF300T is rooted. Am I confused & talking rubbish?
Adding 2 hours later. I rooted the device using XDA guide. Still trouble to reboot device. It always reboots into TWRP, then I have to connect it to PC & reboot with ADB commands. This isn't right...

Go manager does not have the proper twrp for our tablet.
Rooting is no longer required to flash twrp. Motochopper will root with just adb.
I suggest we try to get everything working properly with stock before changing or adding anything.
Go to to this link and download the stock Asus firmware 10.4.2.20. Choose the proper sku for your location (ww, us or whatever). Don't forget to thank philos64 while there. Unzip once and place on your tablet, flash with twrp, if that fails unzip again and place the blob file in the directory with adb and fastboot and flash with fastboot. Verify everything works properly before making any other changes.
Thank you for the donation offer.
I don't have a method to receive donations. A simple click on thanks will be good.

My problem is that because I installed wrong TWRP by mistake - it can't mount anything & I can't install anything from SD or internal memory. So, should I delete existing TWRP somehow &/or replace it by CWM recovery?

No don't delete twrp or install cwm. We should have access to adb and or fastboot. We should be able to use either to get sorted.
Go to to this link and download the stock Asus firmware 10.4.2.20. Choose the proper sku for your location (ww, us or whatever). Don't forget to thank philos64 while there.

exit

May I ask you then? My ROM number is: JOP40D.WW_epad-10.6.1.15.3-20130416 & as I can see from numbers you are offerring me to downgrade (from 4.2 to 4.1). Will this not kill the device? And why can't we re-install existing ROM through ADB? I'm not arguing, just trying to understand.

[Q] Nexus S not working...

I'm going to probably get a lot of hate for this because there are a ton of forums that might get me here. I did search for about 3 hours tonight and discovered some things but am still confused. I hope someone can help this be more simple. So a friend has a Nexus S that isn't working (I have a Nexus S by the by too). It's unlocked but no ClockWork on it. I can press volume up and power to get to fastboot mode. When I click on "reboot," the phone will just loop on the Google logo. If I click recovery, it starts to boot then shows the triangle with the exclamation mark. From there, I can press power and up or down on volume to get the blue screen which says reboot system now, apply update, wipe, wipe. You get it. I'm stuck...I can also turn off the phone, hold volume up/down and plug in the usb to get to "downloading..."
I want to get this phone working and back to stock. I have the SDK Manager (my phone isn't rooted so I use it to take screenshots) and pda net (which I still don't understand why or how to use with this) and two versions of Odin. It seems like Odin can get this working but I can't get it to work or find a clear guide on how to use it and which ones to use. This is a Tmob Nexus S, I think the i9020. Any help would be so greatly appreciated and I will give you all the credit. Oh, and i can pull up the device on ddms with the sdk manager and can explore the files but there is nothing. I can't find a way to drag a file on the phone to "apply update from /sdcard." Sorry again and thanks again!

It seems your boot.img file either corrupted or missing.
Find a working copy of file, flash it via ADB interface or fastboot. Flash recovery file CWM. If that doesnt work, Try flashing CM7 Rom or someother ROM.
Did you check http://forum.xda-developers.com/showthread.php?t=895545 ?
Odin should be your last resort, if nothing really works for you.
If you want to return to stock, simply flash the NAND backup found here: http://forum.xda-developers.com/showthread.php?t=884093 .

Thanks so much for the quick reply. I think I've made some headway...I can "see" the device with cmd by typing adb devices. After that though, I don't understand how to get the stock nexus s rom on the phone. How do I move that file to my phone (what's the line of code I type)? I've tried "adb install <c:\grh78> but it says the syntax isn't correct. Any more help is so greatly appreciated and I appreciate the already prompt response. Thanks!!!

Download your rom of choice (stock, custom)
Flash Cwm via fastboot if you haven't already
Boot into recovery.
Use adb push to push your zipped rom to the sdcard (adb push file.zip /sdcard/file.zip)
Use cwm to flash this zip.

Wow fast responses. I bet it's annoying to help yet another person having issues (again, phone was given to me like this but yeah...) while you guys or gals already know how to do these things very well. Here's where I'm stuck. I enter this code in cmd:
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
and it just says < waiting for device >.
Here's a pic of the screen that I'm on with my phone when i enter the command.
http://imgur.com/Pey3W
If I'm just in the first screen by holding volume up and power, the computer won't read the phone. So I click recovery, the screen shows it's trying to install something then the triangle exclamation mark, i press volume up/down with power and get this screen and the computer can "see" my phone on cmd.
How do I get this flipping clockwork on this phone or get the stock image on my sd card? Thanks again for helping me out guys. I have taken a look at the links you have sent me and that's where i found the download as well as the code to enter. I will keep looking at them but if you find a faster solution, please let me know.

So you already tried "fastboot devices" while in fastboot mode?
Edit: Actually it sounds you really want stock so download the complete stock OTA ROM (including boot.img etc.), rename it to update.zip and put it on the root of your sdcard. Boot into the stock recovery like you did already and hit apply update.
EDIT: Go here to download the correct OTA http://forum.xda-developers.com/showthread.php?t=1056062
Find the correct 2.3.6 "Full ROM" for your phone model. Sounds like in those instructions you don't need to rename to update.zip. Haven't seen stock recovery for a while so I don't remember.
If there is a wipe option in the stock recovery then do that first.
Yes I have tried fastboot devices in fastboot mode but nothing because my computer doesn't read the phone in that mode. And yes, I want to put the stock rom on there but that's the key, I can't get access to the root of my sdcard. I can't push anything into the sdcard to flash it. Any ideas what to type or how to access the sdcard? Thanks a million, billion.
Also, I can't get the phone to boot at all, like I can't get passed the Google Logo if I reboot so I can't access the sdcard in the traditional way.

If fastboot devices returns NOTHING then this is most likely a driver issue. Remove the device through device manager, make sure you have a recent SDK (for the USB driver) and let it re-detect.

If you can get into the boot loader and get a proper USB driver you should be able to flash a recovery.
Once you've flashed Clockwork Mod (recovery) you'll be able to push to the sdcard using ADB or possibly mount the sd card through the CWM menu (although I've yet to have that work).
In order to get a recovery flashed though you need to get fastboot to see your device (unless you can already boot into recovery, then just use ADB).

If he's stuck at the Google logo and has a trash boot.img it's not likely he'll be able to get a shell via ADB. Now, if the system is hanging starting a device or looping during boot then that's possible.

He said he can access stock recovery and has connected with adb, unless I read wrong.

Indeed - I saw no clockwork and figured he'd toasted his recovery image as well, but it does look like stock recovery is there. ADB should push fine to the sdcard from recovery then.

That noise is that it detects a device has been connected (assuming a recent version of windows). If you want to flash CWM you need to get the driver sorted for the device. No amount of plugging/unplugging is going to fix it.
If you have the stock recovery you can boot into the stock recovery, use adb to push the full OTA package to the sd card and then just flash that from the stock recovery.

Go to the stock recovery like you have done before and type the adb command I wrote above.
Thanks is all I can say. Okay so when I type in the command, this is what I get:
- exec '/system/bin/sh' failed: No such file or directory (2) -
the "stock recovery" I can get into is the picture I posted a link for. That's what I can access as well as the fastboot mode when I first turn on the phone with volume up/power. But when my computer makes the noise that it's connected (using Windows 7 64bit) it makes a different sound then the normal "device connected." Like it's corrupted.
by the way...if we can get this working, I'll post a picture of me holding the fixed phone!

[Q] How to unbrick my tf300

Hi there, Can anyone help me to unrick my tf300, its stuck on the logo screen.

You flashed a PRIME rom to your tf300?
First of all, we should know which firmware do you have before your tablet doesn't boot (Stock ICS, JB, Custom Rom).
Then, you can use fastboot to recover your tablet (i did it a lot of times). Try steps below:
1. Download latest oficial Asus firmware (V10.4.2.13). BE SURE to download your region (WW, US, etc...)
2. Extract downloaded zip and take blob file.
3. Download Android SDK and install them on C:\ (http://developer.android.com/sdk/index.html)
4. Execute SDK downloader and mark tools and platform-tool options for download.
5. OPTIONAL add tools and platform-tool folder to PATH, after that test if fastboot command runs on CMD.
6 Copy blob file on same SDK folder.
7. Connect TF300T with usb cable and put it in Download Mode (USB icon on recovery menu)
8. Wait until drivers are installed.
7. Open CMD, go to Android SDK folder and then type command below:
fastboot -i 0x0B05 flash system blob
wait 2 or 3 minutes and then you'll see a message that send and write was OK. Now type this command:
fastboot -i 0x0B05 reboot
And It should boot again.

Yes, that's right, but I suppost if he tries to flash a custom rom he has already unlocked his device. You can't flash any rom without unlock bootloader.
I cant do anything apart from get on to apx mode, from apx mode how do I use command to flash back.
My tf300 is ics, unlock.
when i connect usb to pc. i press power and volume up. thats only things i can do.
so what do i do next?
thanks.
The same problem.
I only see: "device is unlocked" or something like that. And nothing go on.
Is it totaly bicked or is there any chance to restore it?
Please advice.
Did anybody ever figure this out. I'm in the same boat. Can't do vol down+power to get to recovery. But if i do volume up+power it shows in device manager as transformer prime apx interface (even though it's just a tf300)

no way to unbrick tf300t
Funny, I bricked my tf300t without doing anything. One day it just got stuck in asus screen.
tried to recover, nothing happended.
tried hard reset. Nothing.
Wipe data: result: bricked tablet.
I'm looking for information it is defintely impossible to unbrick it.
Anybody else with the same situation can tell you that.
Nobody has even been able to do it.
If you send it to Asus they provide a new tablet.
Conclusion:
TF300T is a terrible product, as any other asus product i assume. Amazing that you can brick a tablet without even trying to flash it or without even being connected to a computer.
It bricks by itself. Hundreds of other users can confirm it.
My advice: dont by asus products
If you already have one, dont use wipe data as anybody who has done it has ended up with an expensive useless brick.
Odp: [Q] How to unbrick my tf300
I don't agree witch this, only think what you not should use is t the wipe data from bootloader menu - I already flashed many times not working kernel, get really often bootloop - the problem is - much users going to made stupid things when the get a soft bootloop - If you get this first try wipe data from recovery, if this won't help, try to format data from recovery - often happends that the ext4 filessystem get broken. Recovery should allowa us to run fsck on data - I fixed my bootloops many times with it without loosing my data.

OP,
I think your anger is misdirected. The device, as it comes out of the box, works 100% without issues. YOU as a user decided to make changes that could potentially brick it. YOU chose to follow the steps with the full disclaimer that it can/may brick your device. So at the end of the day, its' not the fault of ASUS or the device for "bricking itself"; the responsibility of your actions lies on your own shoulders.
That being said, Asus will not provide warranty support for a tablet that has been unlocked. This is clearly stated in their unlocker app. So no, they won't "send you a new tablet" if you send it to them (unless you pay out of pocket for the repairs).
I've done just about as bad of a brick as I possibly can on my tablet and recovered just fine. It was just a matter of being CAREFUL, reading instructions three times before l followed them, and asking lots of questions. But what ultimately saved me was the NVFlash tool, and for that I am eternally grateful.
Just my two cents.

I have problem that my partitions won't mount at all. I have access to fastboot, CWM, and adb but no matter what i cannot access my partitions and so i cannot install zip from CWM. When i try blob within fastboot my tablet just freezes.....
Hi, what happens if I have no access to fastboot? It loops in the ASUS logo and what ever I do, can't gain access to recovery because it doesn't get into fastboot. So how to solve it via APX? Thank you.
You wont solve the problem unless youve done a nvflash backup. If you tablet is recognised as APX while plugged in PC, then you have an unrecoverable brick. If nothing appears when you plug it, then try on another PC.

Hi,
I am having a similar problem to the one described. I have unvblocked my TF300T and installed CWM recovery (v. 6.0.2.3), but it can't mount any filesystem, so I can not flash anything. The boot menu is gone (RCK, wipe tablet, android) and when I switch the tablet on It just goes to CWM. If I connect the tablet to a PC, I can send commands with adb from my win 7 PC (for instance "adb reboot" will reboot the tablet), but fastboot doesn't work (it keeps "waiting for device"). Prior to this my android version was JB 4.2. I didn't make any backup, so I am fearing the worst outcome. Did I brick my tablet for good?
Thanks a lot for any reply.
TF300T blocked on boot screen

My Asus TF300t is blocked on boot screen after try to install a new rom on JB 4.2.2.

I tried to install several roms, offical or not but the problem is the same, "The device is unlocked" on the boot screen Asus...
I read the previously posts and :
- i installed on my pc the sdk
- i dowload the "blob" file and i placed it on tools directory
- but, the actually problem is whis the lign "fastboot -i OxOBO5.... (i have copied and paste it on schell command) and enter
load_file: could not allocate 820157833 bytes
error: cannot load "blob": not enough space
can you help me please ?
i want to resolve this problem with you to install the best rom for this model.
Thank you very much and sorry for my english, i am french but i understand your paragraph.
See you soon

If you have mounting / PIT errors you could try my solution as described here:
http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
no guarantee though but it basically wipes your device so that you should be able to flash the blob file back.
also if your tab still is ICS- check if you are using the correct recovery - also bear in mind that cm10.1 afaik uses the new 4.2 bootloader and probably wont work with ics based PIT devices.

Hello man,
I try your method but the problem is the same when i want to copy the blob file, "not enough space ..."
fastboot erase system OK
fastboot erase recovery OK
fastboot erase userdata OK
fastboot erase boot OK
fastboot erase misc OK
fastboot erase cache OK
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob PROBLEM
The message is the same like previously, always the problem of space.
I tries the method by copy the blob file on different directory on my computer and on a usb key too.
Always the same problem of space
I think the problem is the space on the tablet but i dont' understand. I erase system, recovery, userdata, boot, misc, cache, i think the tablet is empty.
Can you help me please ?
Thank you very much

which blob file did you use? Was the zip appropriate for your region? also what was the last stock rom version you ran - you said you wanted to update to 4.2.2 - what was the old version?

[Q] ROM manager clockworkmod update bricked tf700

Hello there!
I have a TF700T pad, I installed free rom manager application, from within that application I chose to install clockworkmod recovery, the application loaded the clockworkmod recovery from the internet (there was an indicator on top of the application screen).
After finished, I rebooted into recovery, but it doesn't reboot to recovery, it loads android normally, then I tried to boot to recovery manually by pressing and holding the the power button along with the volume down button it loads nothing and stays there for ever!! I did this several times then it it changed and now it doesn't even load the android normally.
And when I boot into APX mode, the adb can't find it!
In short, I can't access recovery nor system!
When I try to boot to recovery
(power + volume down) It freezs and the following shows on the screen:
"The device is unlocked.
Android cardhu-user bootloader <2.10 e> release by "CN_epad-9.4.5.30-20120907" A03
Checking for android ota recovery
Booting recovery kernel image"
- I downloaded the firmware from ASUS and renamed it to "EP201_768_SDUPDATE" and copied to the root of a formated FAT32 micro SD card and tried to boot, but still freezing on above mentioned screen.
- The PC recognizes it (drivers are correct, i downloaded them and installed them) but the adb can not find the pad and tells me to install tap's specific drivers!
- I tried to flash the recovery image image.img through adb, but same problem, it stays there for ever showing the message "waiting for device".
Please, help me with a solution for that situation!
Thank you.

That would be the only remaining option, but ROM Manager is known to do this. If a user cannot even read on a forum before doing stuff, I'm not sure this is going to work out very well.
OK. I'll go back to my hermit cave now.
No, I can only boot in APX mode!
Isn't there any way we can make the adb reconize and access the PAD?
I can bring the recovery image and put in the root of the SD card, but what should I name it so the boot can reconize it and update? (the device says "checking for android ota recovery" !!

APX is NOT adb -- you need to issue commands using fastboot. Did you use the manufacturer's switch? "adb devices" won't return anything, even on a perfectly healthy 700. Take a look here:
http://forum.xda-developers.com/showthread.php?t=1926286
and don't forget to use that switch: -i 0x0B05, as in
fastboot -i 0x0B05 <command>
For example, fastboot -i 0x0B05 devices or fastboot -i 0x0B05 reboot
EDIT: APX = FASTBOOT, for clarity.

APX is also NOT fastboot - in APX mode you can *only* use nvflash, but for that you'd need to have created the blob before bricking.
I am sorry, I didn't really understand what you are trying to say!!
What does "manfacturer's switch" mean?
Also, what does APX = FASTBOOT ?

You're right. I wasn't mad/annoyed at your post. I just wanted to point out it has been known for a while now that ROM Manager does funky things on the 700. I'd just stay away from it -- iIn the sense that if one aspect of a program is broken by a device's particulars, changes are relatively high that some other aspect(s) is/are broken as well and you might get to know which one(s) that is/are by first-hand experience.

[Q] Custom ROM on TF300T

HI all,
I am VERY new to this custom ROM stuff, and I am a bit confused. I have an ASUS TF300T Transformer Tablet. It has 4.2.1 loaded, build is JOP40D.US_epad-10.6.1.12.3-20130416. If more particulars are needed, I can provide.
I have rooted the tablet (I used motochopper to gain superuser access), thinking that would allow me to load a custom ROM. I was WRONG (as most of you probably know). I want to load a custom ROM (CyanogenMod), and also not use the ASUS preloaded software. I want something with less bloat, is faster, and something I can customize at will.
So....I have read a ton of posts on this, but I can't seem to find a step by step single, simple process to accomplish this daunting task. Simply put, I need step by step instructions that can get me where I want to be. At this point, I'm not so sure I could be more confused! LOL!
Anyone who has done this, or is experienced with this, I could use some major league assistance!
I want a faster, more "open" tablet. I also know I don't want to brick it. I definitely don't need a 300.00 paperweight!
Any help would be greatly appreciated.
Thanks!!
Scar!

You need a custom recovery! download twrp here: http://techerrata.com/browse/twrp2/tf300t
DOWNLOAD THE ONE THAT SAYS "openrecovery-twrp-2.5.0.0-4.2" and flash it with fastboot in cmd " fastboot -i 0x0B05 flash recovery twrp.blob" make sure you rename the blob to "twrp.blob"
*update your info your bootloader is "10.6.1.15.3" instead of "10.6.1.12.3"

You can also follow this guide. It explains what you need to do pretty well. But you do need a custom recovery, which i prefer TWRP http://forum.xda-developers.com/showthread.php?t=2187982
I was confused at first too. I think they need to change the wording in the tutorials. They say "If you're on JB bootloader, this twrp, if you're on 4.2 BL, that TWRP" and i was just thinking... WTF, both of them, 4.1 and 4.2 are jellybean.... it should be changed to 4.1 BL and 4.2 BL, none referred to as JB.

if you installed root on your device you should have adb and fastboot, right?
if you are on windows(pc) press the windows key + the R key and type cmd in the search box, then press enter now navigate to the adb/fastboot directory on your pc by typing "cd <the location of the file>" then plug in your tablet in fastboot and type " fastboot -i 0x0B05 flash recovery twrp.blob" what does this do? this command flashes twrp over the stock recovery, with twrp you can install custom roms! after you have done this download a rom you like (watch out for bootloader versions! if you are on stock 4.2.1 i would reccomend the latest unofficial AOKP or the latest official cm10.1) if you download a rom you can see it is a zip file, place this zip file on your sdcard and power up your tablet in bootloader by holding volume down + power button till icons pop up! now press the volume up key when the RCK icon is blinking! now twrp should start, now click on wipe and then advanced wipe and wipe system data cache(you don't need to wipe your data if you prefer to keep it!) now go back to the main menu of twrp by pressing the home button in the top right corner, now click install and navigate to the directory you have placed the rom in, after install reboot!
I've a TF300TG but I think my question is associated to the title of this thread. Do I have to note the sku of my Pad or isn't that important when I flash a custom Rom?
In the threads of many custom Roms I've read nothing about the sku. So I'm not sure if I have to take care for this.

if you are on windows(pc) press the windows key + the R key and type cmd in the search box, then press enter now navigate to the adb/fastboot directory on your pc by typing "cd <the location of the file>" then plug in your tablet in fastboot and type " fastboot -i 0x0B05 flash recovery twrp.blob" what does this do? this command flashes twrp over the stock recovery, with twrp you can install custom roms! after you have done this download a rom you like (watch out for bootloader versions! if you are on stock 4.2.1 i would reccomend the latest unofficial AOKP or the latest official cm10.1) if you download a rom you can see it is a zip file, place this zip file on your sdcard and power up your tablet in bootloader by holding volume down + power button till icons pop up! now press the volume up key when the RCK icon is blinking! now twrp should start, now click on wipe and then advanced wipe and wipe system data cache(you don't need to wipe your data if you prefer to keep it!) now go back to the main menu of twrp by pressing the home button in the top right corner, now click install and navigate to the directory you have placed the rom in, after install reboot!

OK, first, I am on a MAC. I have "terminal" for CMD lines, so, it should find whatever files I need it to find just as the windows CMD block will.
I have "fastboot and ADB" in a folder on my desktop, I have named the folder "android". I also downloaded the TWRP for 4.2.1 (renamed to TWRP.BLOB). I think I have all the files I require, it's just a matter of what steps to take. I also have the CM 10.1. This is the ROM I would like to use.
I was also reading that using TWRP, I am not supposed to wipe. I guess, theoretically, I want to be able to boot to the original ASUS ROM in case anything goes wrong. Otherwise, I wouldn't have a ROM to boot from.
I'm not sure if everything I am saying is correct, again, I am very new to this and trying to undertand exactly what I am doing.

The fast boot and adb you have are most likely windows files. Not sure if there is fast boot and adb for Mac.

Any possibility of kicking this to the top and maybe getting this tablet accomplished tonight? I believe I have all the files I need (for MAC), and I am ready to go. I just need to know exactly what to do.

I can TRY to help. I have no mac, never used one, dont know the procedures for getting the drivers and stuff installed on mac. So, im going to assume you have the fastboot drivers installed properly.
NOTE: IF YOU'RE TABLET BREAKS, NEVER TURNS ON AGAIN, OR GOES UP IN SMOKE BECAUSE OF MY DIRECTIONS, IT'S ALL YOUR FAULT AND RESPONSIBILITY NOT MINE. GET OVER IT AND BUY A NEW ONE.....LMAO.... really though, i am helping as best as i can and you always run a risk flashing devices and thats your risk, not mine.... but if you follow my directions exactly, you will be jsut fine and not have a broken device...
First, make sure you're on the latest update from asus. Should be a bootloader ending in 15.3 and android 4.2.1 .
Second, unlock your bootloader. Unlocking the bootloader is quite simple. Download this: http://d-h.st/86c Install it on the tablet and open the app (its a RAR file so it needs extracted first) Follow the directions it gives you, if i remember correctly, you just click yes or something, tablet reboots, and the bootloaders unlocked. If it sucessfully unlocks, when you first turn the tablet on, in the top left corner of the screen, it will say unlocked.
After bootloaders unlocked, turn the tablet off. Power on the tablet by holding the power button and the volume down button at the same time. This will take you into bootloader mode. One quick thing to make sure you are on the latest bootloader. The bootloader screen should have 3 icons to choose from, if it has 4, you are on the old/wrong bootloader and need to go back and update your system before proceeding. If 3 icons, you're good to go, plug the usb cable in the tablet and in your computer.
Download TWRP recovery now. This is the part where you dont wanna screw up, downloading and flashing wrong recovery can equal a broken tablet. Download this exact TWRP recovery: http://diesburg.co/tf300t/twrp/openrecovery-twrp-2.5.0.0-tf300t-4.2.blob
Put that file in the folder where fastboot is.
Now in your terminal/command line, go to the directory where fastboot is. With tablet plugged in and in bootloader mode like mentioned above and terminal in the fastboot folder, type: fastboot -i 0x0B05 flash recovery openrecovery-twrp-2.5.0.0-tf300t-4.2.blob and press enter .... this will flash TWRP recovery to your tablet using fastboot.... if you get something like "waiting for device" in your terminal window after typing this and it never gets past that, thats where i cant help, drivers for fastboot or something isnt right.... if it works, hell yea, onto the next step....
Reboot the tablet, type: fastboot -i 0x0B05 reboot and press enter.... let android fully boot up, copy your ROM to your tablet and dont forget the gapps package for the rom..... now turn the tablet back off......
power the tablet back on like before holding power button and volume down.... once in here, RCK will already be highlighted, if its not, use your volume down key to get it highlighted... once highlighted, hit volume up and this will boot the twrp recovery you flashed......
Once in TWRP, (FIRST DONT FORGET CLICK BACKUP AND MAKE A BACKUP OF YOUR CURRENT ROM!!!) now, make sure you can see your cyanogenmod rom file and gapps by clicking install and going to the ocation where its at, if you see the 2 files, click the back button to the main screen.... on the main screen, click : Wipe, then click factory reset.....after that, go back to the wipe screen, and click system to wipe the system partition..... now go back to the main screen again....
Click install, then click to install the cyanogenmod rom.... after it installs, install the gapps package.... after that, you SHOULD be good to go, reboot the tablet by clicking reboot to system.....
I think that covers everything..... now in the future for flashing other roms, always wipe before flashing and flash the roms the same way you did this one.... just so you know, not ALL roms require gapps package.... most specify whether they do or not....
Any problems, let me know unless its the "waiting for device" thing, i cant help with mac drivers, someone else will have to

So, no matter what I do, the bootloader has to be unlocked, correct?

for a custom rom, as far as i know, yes
but for just root on stock rom i believe theres ways to root stock without unlocking the bootloader

I simply cannot seem to get the MAC to do this. I just don't know what command lines to use in the "terminal". I am amazed that no one has flashed their tablet with a MAC.
Anyone who has done this with a MAC, please drop a line if you can. I would really like to get this done if at all possible.
I am unlocked, I get all the way to the "flash" commands, and then it seems to not want to cooperate.
HELP!

I wanted to close out this thread and thank everyone who jumped in to try to assist me. I was not able to flash my tablet, nor get the Cyanogen mod loaded. Not sure why, but, as I try to load TWRP, I get a "permission denied" error.
Eventually, I will get my hands on a windows computer and give this another shot. But, it should have worked on my MAC as easily as anything else. Not sure exactly what I am doing wrong, but, my tablet is working just fine so, I know I did not "mess" anything up (YAY).
If someone has been able to "flash" and put a custom rom on their ASUS Transformer using a MAC computer, please get with me and let's chat!
Again, thanks everyone for taking some time to walk me thru this! I learned a lot, so your efforts did not go to waste! I great appreciate it!

not sure exactly how a mac works but i believe its some sort of linux. can you by chance start the terminal with "administrator" priveleges or type "su" in the terminal to get root priveleges? Just my thoughts with a "permission denied" error, you dont have administrator/root access.
In that link i shared above about mac and fastboot, it says to use " ./ " in front of every command. So try the fastboot commands i said above to flash the recovery but do it with ./ infront like this: ./fastboot flash commands

Well, I used Motochopper to root my tablet, so, I'm not quite sure exactly what you mean. So, I am rooted, my BL is unlocked.
My tablets boots in "fastboot", I just can't seem to get the flash done. At this point, I am not so sure I could be more lost. LOL!

In the steps I told you above. The part where you do the fastboot commands in the terminal. "fastboot flash 0x(somenumber) recovery twrp.blob"
put a ./ in front of the fastboot command... so its "./fastboot flash 0x(thatnumber) recovery twrp.blob"

[Q]Stuck in bootloop with deleted OS, abd not working.

Hey all,
I have a big problem with my TF700.
I wanted to root my device after unlocking the bootloader through the app, but by being dumb I managed to delete the OS in TWRP (thought it was factory reset) and now I'm in big trouble.
The only thing the tablet loads now is the TWRP 2.2.1 recovery. (TWRP came with a root-package, I didn't install it myself.)
Since I can't load an OS that is apparently deleted, I'm stuck with using the (latest) SDK to get the stock rom back on the tablet.
The problem is, it doesn't work, at all. The device is recognised by my (Win7) PC and the 'adb devices' command gives me the ID and 'recovery'.
If I try to push the ROM to the Sdcard folder (or any folder, for that matter) It gives me a "protocol error" with no other explanation.
If I try to sideload it it is stuck on "Waiting for device".
I tried the 'shell' command, just to see what that does, but it also gives me an error.
Other commands can also give the the "error: closed" message.
Since both of those commands don't work, I can't get anything on this tablet, since I can't get this version of TWRP to mount an external (micro) SDcard, the option simply isn't there.
Can anyone help me with this, of has my tablet been reduced to an expensive paperweight?
That's the problem with packages - you don't really know what's in it...
What root package did you use?
You have a very outdated recovery installed. I'm guessing here, since you didn't post your bootloader version and that's the first thing we need to know!
Can you still get into the bootloader?
Boot with Power and Volume Down buttons until you see the tiny script and post your bootloader version. Should be something like 10.6.1.....
Do NOT do anything else in recovery at this point!!!! If it is incompatible with your bootloader you could hard brick!
Once we know if you have fastboot access and what your bootloader version is, we can help you to flash the correct recovery in fastboot. With that installed it's a piece of cake to get you up and running.
But be patient! Don't do anything else you're not quite sure of!
*Update Below*
I believe the culprit was the 'Install recovery' method "Scott's Recovery install tool"
I tried a few but most didn't do anything. Every tool I tried comes from the xda forums and checked youtube videos explaining the steps.
If I boot using Volume down + power, nothing extra happens. I just see in the left hand corner "this device is unlocked", since I unlocked the bootloader using the ASUS app.
If I use the command adb reboot bootloader, it goes to TWRP 2.2.1.
Does this imply that I also deleted the bootloader?
Update: I deleted all drivers and software regarding the tablet from my PC and I installed the adb setup package from these forums and reinstalled the (universal?) driver package. This turned out to be a newer version of adb, and I actually managed to push a file to the tablet with no problems. I am reluctant to try anything else at the moment, since this whole ordeal had given me quite the scare (and the desire to learn more about this all)
Can anyone help me revive my tablet?

Ok, good - you got adb working. The adb command to boot into the bootloader is
Code:
adb reboot-bootloader
Note the hyphen
Also I wonder if you pushed Power and Volume Down long enough. You should feel the tablet vibrate twice, then see some tiny script and 3 icons appear. That would be the bootloader menu and in it, you are in fastboot mode by default.
The next step would be to check if you have a fastboot connection.
The command for that is
Code:
fastboot devices
Read my guide on flashing a custom recovery and rom very carefully and follow the steps outlined to get TWRP 2.8.0.1 on your tablet.
Ask any questions you may have in that thread.
http://forum.xda-developers.com/showthread.php?t=2688891
Edit: Sorry, forgot that we have to determine your bootloader version first. So use the button combination or the adb command to boot into it and post it. Don't worry. I don't think you did anything to the bootloader - it's not that easy to mess it up...
Unfortunately, the adb code doesn't work, with or without the hyphen. The device will reboot, but will return to TWRP.
I've held down the Volume down+power button for more than a minute witout result. The device will just reboot after a while for as long as I'm holding it. I do see the screen flicker for a second.
I've also noticed, that after I push a file to the tablet, that after a reboot it loses the data I just moved.
After booting TWRP, when I look in the command line of TWRP, it tells me that it can't mount the 'system' , 'data' and 'cache' forders. (tw_mount)
And it specifically mentions (multiple times) that the /data folder failed to mount, giving the message "No such file or directory"
It seems I really managed to F'ed it up good...
My "force-boot-to-bootloader" kernel module might help you unbrick. Read this guide very carefully before you do anything:
http://forum.xda-developers.com/transformer-tf700/help/guide-t2853546
You people are my new heroes!
The last guide did the trick. The stock firmware is installed and I'm currently updating and installing all the apps.
Thank you all só much, you really saved me a ton of frustration.
