[Q] I need help! My TF got stuck and can't boot into recovery!!!

My Tf got stuck at the logo Eee Pad boot after I tried to restore the old rom, and now it can't do anything except boot and stuck at the logo.
I tried the nvflash unbricking technique from rayman84 : http://forum.xda-developers.com/showthread.php?t=1123429
, but my TF only listed as unknown device when I tried to get to APX mode and it also said,
"This device is disabled because the firmware of the device did not give it the required resources. (Code 29)"
Now I don't know what else to do. Please help! I hope I am not completely bricked the device yet.

Have you tried the button combo to get into recovery?
Press and hold the Vol down + power button.
When prompt, you'll see lines of words at the top left of the screen, push the Vol up button immediately within 5 sec to get into recovery.

Apparently, I didn't know the button combo. Anyways you save my niece's TF. Thanks a bunch
Edit: although the tablet is working now, it still got the message usb unknown device. Do you know how to fix it?

Hi, i don't know if i should post a new thread but my problem is almost the same as bengob3t's one.
I have a brand new TF101 with a B70 Serial number, but i successfully rooted it using the RazorClaw Tool. Then i tried to install clockwork mod followin this topic : http://forum.xda-developers.com/showthread.php?t=1106587
I directly applied the instructions from step 8 (download hashmyfiles etc...) and i rebooted my Eee pad manually step 13
I didn't see any progress bar, but my device is stuck on the Asus screen, and the speakers make stange noises at regular intervals.
I am able to go into recovery though (power + vol down then vol up) but the factory reset doesn't work, and i cant really do anything (at least not anything that i know what it is).
Is my tablet definitely bricked ? If not, how can i bring it back to life ?
I wasn't able to use NVFlash, as i can't seem to go in APX mode. I press power+vol up, i hear the sound usb device connected and immediately after i hear the sound "usb device disconncted"
Nvflash says
"Nvflash started
rcm version 0X4
Command send failed (usb write failed)"
Thanks in advance for your help.
EDIT : When i put the micro sdcard from my phone into the tablet, i am able to mount it. So i will probably be able to flash something from it, but what ? Do i have to flash a recovery ? Directly a custom rom ?
I'm a little lost, but i'll try to give you guys as mush info as i can find.
EDIT2 : I flashed the PRIME rom, everything seems to be back to normal... if you got info on my situation, don't hesitate to fill me in ^^ i'd like to understand what i did wrong, even though i dodged the bullet.

Do you have the correct driver installed? Do you have Asus sync install on your PC?

hmm.. I'm not sure. I downloaded the unbricked tool nvflash file, and the tool already had usb driver inside it. Is that the driver you were talking about? I never were able to get to the point where I need to point the APX to where the driver located because it always said unknown driver the whole time.

Boot looping on the Eee Pad Screen

Hey guys,
So I looked tried to charge my tablet one day, and it decided to boot loop to the Eee pad screen and continue to do that. I tried to enter recovery and it then tried to restore a backup that I had, it said there was some kind of error and CWM wouldn't work after that. I tried doing a cold reboot but nothing worked. Also I tried EasyFlash and I don't think I did that right either. I was on CM 10 before this happened with Rogue Recovery. What are the steps that I need to take in order to get my tablet up and running again.
PS: I know that there are threads about bootlooping but none of them helped much.

I would love some help...:crying:

It seems like I can't get it into apx mode properly. I installed the drivers and when I plug it in it shows nvidia... under USB universal in device manager. Not sure what I am doing wrong.

Hi.
I have had this problem for four times after trying to flash to a custom ROM, and now my tablet is perfectly functionable.
If you used EasyFlasher to get a custom ROM and now it's bootlooping OR if you tried to root your device and its bootlooping OR if you do not know what you have to do, then check the ways below:
====================
W1:
Power up the device. When it starts bootlooping, hold both Power + Volume DOWN buttons until it will say that you should press volume up or it will enter RCK mod. When that will appear, do nothing. Just let it enter RCK mod and it should wprk. If not, then do W2.
W2:
Look under your TF101 and see if the S/N starts with B60 or under or B90. Start EasyFlasher and select the FIRST button at launch if it is B60 or under or the second if you have B90. In the EasyFlasher's folder you will see a folder with a name like "update" or "puthere". Now go to Asus' TF101 page, to downloads (Link coming soon, until then try to find it) and select the latest (first you find) firmware.Do NOT use a custom rom or you will hard brick it! Download it to the folder I said above. DO NOT EXTRACT IT. Now, make sure your tablet is at least 50% charged so it can successfully flash the stock rom. Then, connect it to your PC and press the Power + Volume UP buttons on your tablet for like 10 seconds. There must be now a NVIDIA driver in your Device Manager. Go back to EasyFlasher and press "Flash/Unbrick/Root". If anything pops up, check carefully what it says. It will probably say to be sure it is in APX mode and if you want to cpntinue. Press yes or OK. A CMD box will appear, exxtracting the firmware you put in that folder. Let the PC and the tablet do it's work. Do not use the tablet while this happens or it may really becolme unusable forever. After it extracts, another CMD box will pop up, flashing the stock fw. If EasyFlasher will say something like "system.bin - 0kb" then the update will fail and your tablet will get HARD BRICKED. In this case, PM me and I will help you. Okay. Now, your TF101's screen should turn on and say "!!!UPDATE SUCCESSFULL!!!" for like three times, and all the CMD windows from your PC should dissapear. The EasyFlasher should now stop installing the fw. Hold your tablet's power button for 5-10 seconds and release. You should now be able to start your device without bootloops. If there still are bootloops, then, do the W1.
====================
I have had alot of experience in bricked tablets, and those ways should wor. For more infos or TeamViewer help, PM me.
I hope I helped,
Kevin.

When it says to make sure that you are in APX mode, just hold Power + Vol UP buttons for 10 seconds then press ok. The drivers you have must show up as a NVIDIA driver in Device Manager when you hold that buttons. Do what I said in the previous post, it helped me four times lol.

[Q] Need Help Unbricking

I just got a transformer pad tf300t, and i am new to android, and just the other day i managed to brick it. i have searched for hours on end for a way to unbrick it, but all the methods i can find don't match my circumstances. So far all i have managed to do it get it into APX mode (i don't know how), and installed a driver so that in Device Manager it says "Asus Transformer Prime APX Interface". Whenever i do volume up+power button, or volume down+power button on boot, it reboots and returns to the boot screen where it stays forever until the battery goes dead. This all happened after i unlocked the boot loader, attempted to install clockworks, and then the battery went dead while using the wipe system data option in the boot menu (or whatever it's called when you do volume down+power button). Any help would be awesome and i would greatly appreciate it.
EDIT: Just sent an email to ASUS about the problem, and of course they weren't any help and just said i might need new hardware (hopefully not true)

Hi, i've met the same problem.
In fact when i tried to update my TF300T to JellyBean, my device didn't want to boot anymore only in Recovery or on Bootloader. So i tried to update the Recovery with the fastboot and install a TWRP recovery with Fastboot in USB and tried to re-install the ROM (CM 10).
But after that, Recovery and Fastboot did'nt work anymore. I've made a video to illustrate the problem (youtu.be/9aSWZrkP_Ec)
This is like that in Loop untill the device has no battery left.
Sorry for my mistakes, i've got an aproximative english
Thanks for any help.

To the OP, if you can some how push a new boot.blob from a ROM and then push a new system blob from the stock firmware, that fixed it for me. I could get into recovery still though so I used fastboot to do this.

Super bricked

I hope I can save it but after 4 hours of trying and reading I can't seem to do it.
I was running an unlocked tf300 with cleanrom. I wanted to update to the newest version of cleanrom and have my tablet on that and ready for school for next term. I downloaded cleanrom on laptop and put it on my micro sd. Went and grabbed the tablet and tried using rom manager to install from sd and backup the os that was on it. Didn't work. So booted into the fastboot spot (vol down and power) and decided i should wipe data since i was there. Went over to that and pushed vol up (once). Let it sit for like 45 minutes and was still on the same screen. Thought to myself well it must be done. Shut off the tablet to restart it.
This is where the problem came up. Now i'm stuck on asus logo. The VD+P doesn't do anything but reboot into the asus logo. The VU+P will put it into a black screen and windows sees it as Asus transformer Prime APX interface. But adb can't see the device. Just device manager. typing fastboot -i 0x0b05 thing just says <waiting for device>
Every post i've read seems to tell people to just push VD+P but if i could do that and get to recovery i wouldn't be doing this. I can't put a blob file into the root sd of the tablet because I can't see the tablet.
Any help would be greatly appreciated.

Maybe this link can help.

Device manager already sees it as transformer prime apx thing though. So i assume by getting it into APX mode doing the VU+P method it is in apx? or is that not mean it's actually in apx?

Apx mode is not going to do you any good. The previous link also provides info on blootloader " recovery " mode.
Try the universal naked drivers from this link and try fastboot again.
http://forum.xda-developers.com/showthread.php?t=1766220
If that does not work leave off ' -i 0x0b05 ' in fastboot -i 0x0b05 command and try again.

Already installed the naked drivers and that's when the computer recognized it in the device manager portion as the asus prime apx interface thing. It still just says <waiting for device> in everything i try on fastboot.

I know you previously said you couldn't get into recovery-bootloader menu but that is what we have to accomplish. Apx mode on this unit is only good if you previously installed nvflash and had all of the proper backup files.
The first link I provided provides 9 ways to get into bootloader menu and from there either fastboot mode (usb symbol) or recovery (RCK). I know some may not work but we only need one.

apx or bootloader menu-recovery.
To use this guide to enter the bootloader menu just use volume down everywhere it says volume up. Everything else is the same.
4. with unit powered on hold volume down and press reset with paperclip - (don't press hard) reset is located about 25mm or 1in below the sdcard
try this one.

Force power off by holding power a few seconds.
Plug power cord into tab with the other end of the power cord not plugged into anything. Hold volume down and plug other end of power cord into pc. This done without pressing power again after it is powered off. Easier to do than describe.

The Problem lies in holding the volume down button. No matter how i turn it on. either plugging it in while holding power down, reset button, letting it die and then plugging it in and turning it on....it just goes into the asus logo screen .

I'm sorry, I did understand that from the beginning but the only things that can save you is get into that menu or recovery or your tab accepts a fastboot or adb command. That is the reason you keep getting pushed into that direction.
My best guesses are out. Sometimes redoing something you have already done twice works.
My experience and all I have read rom manager has issues on this tab. Also many who wiped data from the bootloader- recovery menu reach this same point when they reboot.
Some have recovered by just doing each thing again and again and suddenly something works.

Yeah i fear i'm just going to have to call ASUS . sad panda. i keep trying different methods of doing the VD+P method but it just won't get into recovery.

I'm sorry but I am afraid you are correct. If unable to use adb, fastboot, or get into recovery there aren't any other options. Sorry if I pushed more than I should but I wanted to see a more positive result than calling Asus.
Good Luck!

If you explain you were having issues with your tab and used wipe data hoping to correct the problem. Now when you turn on it just stays on the asus logo maybe they will repair it without cost.
If you go into detail you probably won't get lucky.

[Q] no fastboot no adb wrong drivers?

WHats up guys? My tf300 is still bricked after like 6 months. It started with me flashing the wrong recovery image then a wipe data finished it off. I can get into apx mode and device manager sees it as an apx device with a yellow triangle, or as several different names according to which driver i use. I have tried all the asus ones, the adb, the composite adb, all the ones from the naked driver set. No matter which ones i use fastboot devices returns nothing and adb devices says "list of devices attatched but nothing. Is there something wrong with the way im using fastboot? I just go to the fastboot folder and open a cmd window and it starts like C:\user\fastboot or whatever and im stuck there please help

Questions: what rom did you have before? Did you wipe data from the Asus menu, and not from inside a custom recovery? When you now try to get into fastboot by holding volume down + power, what happens? No matter what, try Buster99's solution. If the only mode you can get into is APX, and you didn't generate NVflash files, then I'm afraid your motherboard is stuck, the only solution to which is replacing it.

i came from stock jb rom and i flashed an ics cwm recovery img i got into the bootloader screen but it wouldnt go into recovery so for some stupid reason i did a wipe from there, from the asus menu. volume down and power just shuts the screen off for a few seconds then straight back to the asus screen volume up and power will apx mode. the driver i had got from asus pulled up transformer prime apx interface in device manager

Must've been the wrong recovery that screwed up your tab. In my experience, wiping data from the Asus menu while you're on stock rom is not supposed to brick it as described by you. Try this method. It has saved quite a few semi-dead tabs. Good luck, and give thanks to the author if it helps.

im sure it was the wrong recovery i dont know why i did it. i had another ics tablet and for some reasone i put both recovery images in the same folder the link u provided is one that i had previously read. I cant even get fastboot to "see" the tablet.
