Hi Guys,
I have the TF101 tablet and anytime I try to reboot it just stays at the first boot screen with the "Eee...." screen. Forever. If I hold down power and vol-down then hit vol up, it just stays there saying its booting recovery image but never changes. If I hold down volume long enough it comes to the factory reset/cold boot screen, if I choose cold boot it will boot.
I have rooted the tablet and had no problems previously, was able to flash roms and whatever else I wanted to do. Also, when I plug the tablet into my Windows XP machine, it does not detect the tablet in any way.
Tablet info:
Android Version: 4.0.3
with 2.6.39.4 kernel
I don't remember what rom its running exactly but I know its a version of ICS
Did you use ROM manager to update your CWM version? This sounds exactly like that, you can try running the bootloop-fix in my PERI tool (link in my signature) to fix, or manually run roach2010's fix found in his latest recovery thread. You definitely need ADB working, otherwise you'll need to Nvflash. (Nvflash Wheelie link is in my signature as well)
You are probably right i very well could have done so in rom manager. Im on vacation and dont have access to a pc right now but am going to try ur tool when i get back. Thx for the info

Wait. I just realized. My pc doesnt even respond when i plug my tab in. How do i run PERI?

Cold boot and install the drivers.
Ok Thing o Doom, you've been great pointing me in the correct direction, however I need some more guidance.
I have installed ADB, and when I cold boot the device and run adb devices I get nothing.
HOWEVER, if I just reboot the tablet, when it's stuck on the EEE screen, I do adb devices and it shows 123456789ABCDEFG.....
My computer doesn't see the tablet when it's plugged in otherwise, nor does any other windows PC in the house. Do you have any guidance as to what I can do? Please help, I need to get this thing running right.
You just need to get to a state where adb is recognized, and 'adb shell' command works.
From that point PERI should work.
Reboot when it prompts you to if it doesn't automatically (Probably won't being stuck on logo)
I can't seem to get anywhere else. My pc recognizes the tablet at the first boot screen but adb shows it as inactive. When I cold-boot the tablet it boots and loads fine but ADB nor any PC recognizes that it's plugged in. I'm lost.
Is "Enable USB Debugging" Checked in Developer Options?

I had rooted/cwm'd my tf101 when I first got it. It was running the 3.1 update at the time. I followed the pure root posts here on XDA.
Sadly I had never tested CWM, and perhaps since it went so easily I didn't really understand/read enough on CWM to understand what is happening. When I ran the 3.2 OTA (OK so I shouldn't have done that, I know now) the TF froze on the initial splash screen.
I've tried many things and read tons of posts here on XDA and other sites, and I'm not getting anywhere, but part of it is I don't know for sure what I'm trouble shooting.
I was using a dual boot laptop in Windows mode when I did the initial update. I had the drivers working and succesfully rooted my system.
What I am trying to do is restore a stock rom for now and I've tried several methods.
1) Asus download SOP - It detects the image on the SD card, checks validity of the firmware, shuts down and reboots and hangs at the first splash screen.
2) CWM recovery, if I understand this right, I Power+ vol_down. I hit the vol_up to enter The screen says
Checking for RCK. press key <Vol_Up> in 5 sec to enter RCK.
I do that and it hangs at:
Booting recovery kernel image
3) I've tried several nvflash posts out there. NVFlash does not seem to be working, I've now done this on two windows boxes. Both the one that used to work, and a clean windows XP machine I had lying around. In both cases, I can get the nvidia APX drivers loaded and the device is seen. However, adb doesn't show any devices, and from pulling apart the batch files and doing some reading, I tried nvflash -r --getpartitiontable myfile.txt and some other commands which always hang. Eventually if I disconnect the tablet - then I get a read error of some sort.
4) quick reboot - every option leads to reboot and freeze at first splash screen.
So questions that I can't seem to find an answer too.
1) If I'm connected in APX mode, should adb show a device? Like I said the PC recognizes it as the APX device and loads the nvidia drivers instead of the normal transformer MTP drivers when I do the power + vol_up.
2) Is there a simple test to use for nvflash? The device shows up, is there anyway I can confirm whether APX mode is working or not?
I'm only starting to piece together the boot process in my own head, and my guess is that niether the stock recovery image or the cwm recovery boot image is working. Would that be a reasonable assumption based on behavior? I will admit I really don't understand the boot loading process in android.
FYI, if I go through Power+Vol_down, wait for rck to skip and then boot without wiping, the TF is fine after that. Meaning as long as I don't try to update, it will work and reboot normally. Root also still seems to be working.
I tend not to suspect a driver issue, since one machine was confirmed working, it's how I got root - and 90% of the time that machine is run as linux. I almost never boot into windows. I'm pretty sure the last time I did was to root the TF.
What happened is you overwrote the cwm when you installed the new update. You can't just randomly install things once you're rooted.
If you have a B7O machine, you need to check that you have the old or new sbk. Go to the general transformer forum, and there's a thread about the new sbk locked bootloader. Follow the test to see if you have one that you can use nvflash with. If that is the case, then go to the dev forum, and look through the nvflash unbricking thread.
Thanks for the reply
First off, you're right and I should have known better. Almost nothing I own runs it's stock firmware, and I just got dumb and didn't do the full research excited for HC 3.2 goodness.
I have a B50 machine, or at least the my serial number indicates that.
I've already tried several nvflash debricking instructions, but it seems that nvflash is not working either. I have several copies of prime and the .11 release from asus. But since nvflash is not behaving as expected, all of those threads are not helping.
I do have the nvidia USB recovery device show up in device manager, but every nvflash command fails hangs at
nvflash started
[resume mode]
ADB devices shows a serial when I'm normally connected, but it doesn't show up when I'm in APX mode. I'm just not sure if the device is in a functional APX mode, since nothing actually runs, despite it showing up in device manager. I've tried googling that situation, but I can only find posts that tell me how to get it to show up in dev manager... It seems like when that happens everyone else has been fine.
WHILE GOOGLING FOR MORE INFO ON b70 - I managed to get NVFLASH working, and now I get what the first command and -r do.
3.2 Update Problem SOLVED
So look at the original post for the strange condition I had gotten into.
Somewhere along the line, the transformer had stopped responding to adb even not in APX mode.
I uninstalled PC Suite and Asus Sync. Then reinstalled only ASUS sync. ADB started working when TF was connected normally
I did not reboot my PC, win7 64 bit. Shutdown transformer, it hung at the splash screen. WHILE HUNG, I held power and vol_up until device manager showed nvidia USB recovery device
I used the stock rom replacement from tabletroms. Sorry I can't include the link as I am too new to XDA.
Got the transformer back up, set up my account, restored data. However OTA from there was not working.
So I went to ASUS, grabbed the .11 image and updates via SDCARD following the SOP instructions.
After reboot, checked for updates, and there was one. Let it do the OTA for 3.2 and now I'm back at having stock 3.2 updated TF.
I will probably root, but may not CMW this time.
I have a sl101. I only get eeepad screen. My son did something to the machine. I can get it to say booting recovery but nothing happens. I also can get a text that says cold booting Linux. Again nothing happens. Nvflash says USB write fail. But when I check adb the device is recognized. Is there a way for me to adb push a recovery in there for me to boot too, so I can reflash a rom. I have a little dilema here. I also was wondering if I can flash rom thru adb. I read once that's how they used to do it on g1. I don't know if I am speaking accurately though. Any kind of light shed on me will be greatly appriciated

not sure about the slider but i had a customer return yesterday with this exact issue on the tf101 and i couldnt get out of it. the tf just kept switching itself back on and getting stuck on the splash screen.
found this set of instructions but im not sure if its what you need or if it will work:
http://androidroot.mobi/technical/asus-eee-pad-transformer-tf101-root-cwm-recovery/
good luck
That is exactly what is going on with mine. The slider is basicly the same thing. I plug it in and I tries to boot. I thought you had to be booted into recovery or the rom for adb to work? That's why I believe this method you just revealed to me. Or some variation of it will work. I will be trying shortly.

nvflash if your TF101 is compatible model.. (must B60 and below).
Or read Wolf's thread HERE. It might helped everyone here..
Thanks but everything needs adb connexion and as apx is not working, i can't connect ADB..
I have a B50 model
Nobody have a clue ?
well, I have to send it back to my reseller that will change it but before that I need to delete clockwork mode or brick it, how can i do ?
I tried every thread here, update rom does nothing, looks like it does not write anything on the tablet
Thanks in advance
try to follow this procedure...
http://forum.xda-developers.com/showpost.php?p=25636698&postcount=5
let me know
Hello, thanks, but as I can't get to apx mode, I can't use nvflash, so still stuck with my recovery, I tried to modify super Wipe package to do things but can't get through...
If someone can make a package to delete recovery, then I can try it on my tablet, I really yneed it to be bricked cause now it load with Rogue's recovery on and on, so the reseller will new it has been modified and I will have to pay to get it back ...
Thanks in advance
with the procedure posted in the previous link you don't need APX mode and don't need NVflash...
Just boot your TF in recovery mode and plug it to your pc...
remove all previous drivers and install the new one that you can find in the post
ciao
ps... at the end of the procedure you will have your TF101 with stock rom and stock recovery
I will try but even when I am on recovery, nothing appears in Hardware management, no recognition from My computer, still strange... And when I power + vol down key, It never says to presse vol up in the text in the upper left corner, just says booting linux kernel...
When I try to boot pressing vol up + power, nothing happens, not even the clics that can be heard when it powers up...
I had a similar issue when I used SuperWipe and discovered my ROM on the external SD Card could not be accessed by CWM
I tried pushing the file with adb but kept receiving errors - protocol, etc. I suspected it was a driver issue along with the fact that 64 bit systems don't always play nicely with drivers. I actually dug up an old hard drive and did a very basic install of 32bit Win7. I booted the Transformer into CWM and when I connected it to my PC - I pointed it to the universal naked driver. I was then able to successfully push the rom to internal storage and used CWM to flash it
Hello,
I tried to connect my tablet to an old Windows 2000, but still nothing happens
Hello every one, I finally sendt back my transformer to my reseller, now I can buy a new one...
Thanks again
My Transformer started rebooting any time I copied anything to the internal SDCard and now will not boot the android os at all. I need to know how to put a new rom on the /sdcard/ and flash it. I can not get the android developers kit to load on my windows computer but i have a second computer that has Ubuntu on it that i think i can use. Can i get step by step instructions on how to do this ubuntu. I have tried everything i can think of and nothing worked. if this does not work then i guess i will need to RMA the unit but it is rooted and i dont know if asus will throw a fit over it. If anyone has any ideas i would be very grateful of the help. Also the rom i want to flash to is megatrons.
Thanks
have u tried cold booting from linux to see if you can get back in to Android?
volume down + power then release both when rck option shows at the top of the screen. you should get 2 options but if you leave it for a few seconds it will auto cold boot.
If that works you can try the fix recovery bootloop feature in my PERI tool, cold-booting whenever you need to reboot the tf. (In my signature)
Well I got it figured out. Unbricked my Transformer on Sunday

Ok like an idiot I went to install the stock Asus rom over my AKOP rom using twrp. Now it just sits at the Asus logo screen and will not boot. How the hell do I fix that?
If you still have fastboot flash cwmand do it again
And if I don't have fastboot? I mean right now if I hold vol down and pwr all it does is turn the screen off. It will not boot into twrp

Turn the screen off? Screen shouldn't be on when you do it, shut it down, then hold Power+VolDown until it turns on and the white text comes up in the corner.
then you will see 3 icons choose the usb icon with Vol- and Proceed with Vol+. Then you are in fastboot.
I got it thanks! She's back up and running.
Hello,
I also have the problem to get stuck in the boot screen. I have a brand new TF300TG, only installed some apps (not unlocked, not rooted). I only made the automatic update to 9.4.4.40, after that it always stops at the boot screen.
What I already tried:
- cold boot
- wipe
- RCK (Android with rotating things shows up short, after that the Android with the warnings sign shows up)
I also downloaded the whole WW 9.4.4.40 package from ASUS and put it on a MicroSD. If I make RCK with this (if I rename the file to EP201_768_SDUPDATE.ZIP) the Android with the rotating thing shows up longer, but I still get stuck in the boot screen.
I already contacted ASUS support and will also return it to a service center, but I'm in China and expect a long process with some troubles, so I wanted to ask if anyone has another idea what I can try?
Ernst
Update:
I think it was now possible to update WW 9.4.4.40 again (renamed to EP201_768_SDUPDATE.ZIP). I now used a different MicroSD with only 2GB. The first time RCK it stopped in the middle of the update (after that the Android with the warning sign came), the second time I tried it, I think it finished, but the TF300TG still stops booting at the ASUS boot screen.
If I try now to update over MicroSD again, it doesn't work.
I have the same problem, only difference is that pressing vol down and power on makes no difference. When its on I also can't turn it off. I just have to wait until the battery is drained.
you have flashed ICS ROM in JB bootloader as far I see - hardbrick if you don't have nvflash files - only service.

Its not me Its the Drivers!!!
So I have a TFT300T, unlocked and rooted, all was fine till i decided to try another ROM. So I installed CWM no problem. Once I installed the ROM problem. I seem to be stuck at the ASUS screen. I have tried loading boot loader to do a wipe and factory reset and that simply boots me to CWM, tried the same thing there but to no avail. So researched bricked Transformer and came across the Nvflash method as well as the Asus Transformer Kit (US ONLY). However I cant proceed cause of the APX driver issue. I tried the included drivers but Win7 wasn't interested. I tried 1 desktop and two laptops, same thing. I even tried my bench tester. Now Universal_Naked_Driver_0.72 seems to install but no communication between the PC and the tab with this driver.
I tried bootloader to try a fastboot command but then the Device manager demands a driver for "Transformer". Same issue. Tried downloading from Asus plus a couple on the web. It seems its the Tablet. I thought to try CWM and an sdcard but it doesn't give me the option to mount it. So if any one knows a fix I would be forever grateful.

I also found the asus transformer kit(us only). But the same problem. I am able to connect my tablet with apx mode, in my device manager I see apx device. but in the tutorials it says that I have to force install de driver, but I don't know which driver to install. I tried the asus driver and every file in the asus transformer kit but nothing. I triend the universal_naked_driver but I can't get it to install can anyone tell me how to proper install that?
Sorry all for those who read my last post in my other thread - "can't root- twrp not working" which makes this post redundant but I'm feeling a little desperate and I'm also new to this stuff. Since I was unable to install TWRP for some reason it was advised I use the old fashioned NV flash method with prime rom, however 'how to' video from the following thread- http://www.tabletroms.com/forums/tr...ment/976-nvflash-unbricking-forever-root.html
has been removed and now I'm stuck with this message on my tablet :
entering nv flash recovery mode/nv3p server
chip vid ----
I hope this doesn't mean I bricked "permanently mt tf101. I've completed the following 3 steps to get this far:
downloaded nvflash zip and prime 1.4.
1 Connect cable to computer and turn device on while holding down Volume Up. Screen will stay off, but USB will come on.
2 (Windows only) Find “APX” device in Device manager and update driver, then point it at usbpcdriver directory from the zip
3 Run download.sh (linux) or download.bat (windows)
In step 2 - driver wouldn't take I presume since I already updated driver when using frederuco's guide. Shouild I have uninstalled APX and reinstalled this version?
Anyhow, after step 3 allot of messages about partioning came up on tablet and now there is the entering nvf flash recovery mode message stuck on tablet screen. Is this right? Am I supposed to flash prime 104 now? If so how? I was advised to install this way as a back door if you will so as I can later install a better rom once I've successfully rooted.
The tablet will reboot when NVFlash is finished, you should be able to follow its progress on the PC screen / CMD window
NVFlash can take a while
There is no cmd window open. I cant remember if there even was one or if i closed it. What do i do now? Do i re-run bat program as shown in step 3?

Basically the entire procedure for NVFlash is this
1: Connect TF101 to PC USB
2. Power Off TF101
3. Put TF101 into APX mode (Power & Volume Up)
4. Run download.bat as Administrator (Right click > Run as Admin)
5. Keep an eye on the CMD window as it will say things like "Deleting partitions > Creating partitions > Sending System / Boot / etc"
6. TF101 should reboot when done
----
If you didn't see the above, just start again from No.1
Yeah, i remember seeing a bunch of messages on tf101 about partioning ect.. . I dont think tf 101 rebooted though. Or maybe it did. This was some hrs ago now since tablet has been stuck with entering recovery mode on screen so i cant remember. I also dont remember if i ran bat with admin privilages. Shall i restart the entire nv flash procedure then? Should i first uninstall and reinstall the apx driver as i sugguested since the one i installed came with a different download pack?

It doesn't take hours to complete, not even an hour, you're looking at somewhere around the 15-30 minute mark, been a long time since I used it
Yea just cancel it, you can't break NVFlash, it is hard coded into the TF itself, its the lowest level communication between TF and PC that will still work even if you messed up your firmware, so long as hardware is fine
Drivers come with the NVFlash ROMs, uninstall the one you have running at the minute and install the one from the NVFlash zip
You'd be better off getting the new drivers ready and uninstalling the old ones while the TF is still connected in APX mode or they will disappear from device manager
These are the ones I use

EDIT - Is your TF101 SBK1 ? (Serial number below B7O)
I went into device manager and uninstalled apx driver like you said but after that I didn't see a way to update apx driver. Holding down vol up/ power didn't seem to be doing anything so I rebooted my PC with asus still attached. That caused the asus screen to go dark which had previously been stuck with the entering nv flash recovery mode/nv3p message for the last 3 hrs. tf101 wouldnt seem to turn on so I plugged it into wall thinking battery may have died but now it still wont turn on. Have I killed my tf101? If not what do I do now? I can feel the charger heating up so pherhaps I better leave it plugged into wall until charger cools down again letting me know it's charged?
Its likely still in APX mode, you'll need to hold power for about 20-30 seconds, then power it on again normally
To install the new APX drivers, you'll need to power it into APX mode while it is attached to the PC USB, then once the PC sees it, point the driver install to the new driver location and install them that way
I plugged back into pc and in device manager it wont let me change apx. It says it already has the best version. This even though i had uninstalled it just before. At this point since i cant see my battery leval im going ro leave plugged into wall for a while and then try running bat file again with current apx drivers and come back here to post my results. Thx for assistance. By the way before plugging back into pc i tried holding power button down for 30 seconds and nothing happened.
You'll need to check the "Delete driver software" box when you uninstall the APX driver or it will just install it again automatically
Likely that driver is fine anyway if it can see the TF
Holding the power button down for 30 seconds just powers the TF off, you won't see anything until you power it back on again
APX mode is 99% black screen on the TF until you power it off and back on normally again
Before i run the bat file- did you say to do it in a cmd prompt? Cause i dont remember reading directions to do it that way. I think before i just double clicked the bat file that was extracted on my PC. By the way i held rhe power button for at least 30 seconds more than once im pretty sure, and there was no activity on my screen
The .bat file will open CMD itself
you were right, when i checked the box "delete driver software" I was able to uninstall. Then after rebooting W8 in advanced settings I was able to disable driver certification which let me update my APX to that of the same folder in which I downloaded the nvflash im currently using. Unfortunately all this had the same result. That is the cmd ran successfully formatting/ partioning ect.. and then like before the cmd said something quickly about being successful and then self closed. Now like before my tf101 is stuck showing entering nvflash recovery message on screen. It never rebooted. Could this be that my tf101 is too new for this method to work? My serial bar sticker came off so I can't check it but my sales invoice is dated june 8 2011 if that helps. Please advise what I should do now

Normally it tells you that it can't find the tablet or fails sending the data if your TF is SBK2, it sounds like something else is wrong somewhere
You could try using Easyflasher, that works on SBK1 and SBK2 TF101s
http://forum.xda-developers.com/showthread.php?t=1688012
That should install TWRP Recovery, and from there you can flash any ROM you like from MicroSD Card
Make sure you choose TWRP recovery though
