[Q] TF101 Stuck in CWM, adb access, no ICS - Eee Pad Transformer General

I seriously searched EVERYWHERE.
My TF101 is now stuck in CWM. The only way to turn it off is a weird way I found out by holding POWER + VOL UP...
If I try to turn it off, it just turns back on. I have full adb access, and I wiped data/factory reset because I was trying to revert back to the original Asus ICS rom, but now I can only get into CWM and if I try booting into Android it just sits there forever. I tried downloading the "US_epaduser9_2_1_17.zip" and tried "adb install" onto the tablet, but it says there is no Manifest.xml
How do I reinstall ICS (stock) back on the tablet AND remove CWM? (Basically completely unroot it)

If you're holding Power + Vol up it's not turning OFF but is simply in APX mode.
What version of CWM?
With ADB you have to ADB push NOT ADB install

I have version v5.5.0.4
I tried adb push but doesn't that just send the file to the tablet?
I can't access anything on the tablet, just cwm. If i try to "install from sdcard" it will say cannot mount "sdcard"
Also more info: I rooted with viper and then unrooted with it.

Try to reboot into system ,then when the screen goes off to do it hold power and volume-. Hopefully a screen will come up with some small print in the upper left hand corner . Let go of the power and volume and let it chill, should cold reboot after 10 sec

Now it doesnt' even cold reboot..
I think I wiped the entire Android system away.
Because when I cold boot it from that menu with the 2 icons, it just stays there when I push ok.
Also, I have a microSD and it won't detect it. I tried formatting with the sd card formatter from the sd assosiation website with no luck. The only thing i can use right now is adb and cwm.

With 5.5.0.4 it only read from the internal sd card.
Did you flash CWM via ROM Manager? If you did go here
http://forum.xda-developers.com/showthread.php?t=1530337
That thread will also show you how to use ADB to push files to the internal storage for flashing

Then you'll have to ad push. The problem is that recovery is ****ed. I don't have a whole lot of experience with adb, for some reason adb won't recognize my tf. I wish that I could help you more

Thank you for that! But, I don't really get the instructions. (I'M SUPER SORRY I'M TOTALLY NEW TO THIS D
while booted into CWM 5.5.0.4 ...
step 1: use adb to push a good recovery [I used Rogue XM v1.3.0 (CWM-based v5.0.2.7)]***
step 2: flash the zip
step 3: use the adb shell to execute the following command
What does it mean by good recovery and flash what zip?
Edit: When I try to push files to the tablet, how do I view them on there? I can't install from sdcard as it says it cannot mount it.

Please help? :/

I SOLVED IT!
I just used nvflash and reflashed the entire Asus ICS rom back on!
Thank you to everyone who tried to help!

ok, i was running 2.3.3 on my ns and finally got it unlocked then i decided to go for it and root it. my biggest mistake was not backing up anything after the unlock and then when i was rooting the phone it got stuck in the google screen
now i can get to the bootload screen but when i go to update from sd; it takes me there but i have nothing to back it up from
ive been trying to figure out a way to load a recovery backup to sd but the pc will not read the sd card anymore...

please help
Question: Do you have clockworkmod on it?
(I figure you unocked and roote via adb/Fastboot - but if you can do it some other way and you did here they are]
Get ADB and Fastboot - figure out how the commands work (from Terminal/console/Command Prompt).
U need to put the files u want to flash (*.imgs in the same place as fastboot/ADB unless you're good a remembering your paths, if you have OS X simply drag and drop commands and files into terminal)
See if you can find a clockwork recovery image,
Download a stock rom - report back
Basically:
fastboot flash boot example.img
Fastboot flash recover example-recovery.img
that should work. I'll keep an eye on this thread.
After flashing CWR, go to mounts and storage and select mount USB storage, from there you can access your sdcard and copy files over.
The USB storage might take a minute or so to show up on your computer, if you're on windows go to my computer and click refresh until it shows up.

Here are the steps to get your phone back up and working:
1.Download this platform-tools.zip and extract it to your desktop
2.Connect your phone to the PC and enter bootloader mode
3.Press and hold Shift while right-clicking the folder you extracted 'platform-tools'
4.Click 'Open command window here' from the pop-up menu. cmd.exe window will open.
5.If the Bootloader is Unlocked continue to the next step. Type in the cmd.exe window 'Fastboot oem unlock' and follow the steps on the phone screen.
6.Type in the cmd.exe window 'fastboot boot cwr.img'.Your phone will restart and enter ClockWork recovery(CWR).
6.In CWR navigate with the volume keys and highlight 'mounts and storage' and select it by pressing the power button.
7.Then navigate down and select 'mount USB Storage'
8.On your PC, go to 'My computer' and press the refresh button until a 'removable disk' drive appears.
9.Double click on 'removable disk', You now have access to your SDcard on your phone!
10.Copy over a flashable .Zip Rom to the SDcard that you want to install on your phone, ie. Stock 2.3.4: Link(only for i9020T and i9023, dont install if you have i9020A), CM7: Link, etc.
11.Select 'unmount' in CWR when done copying files over. Then 'Go Back' to go to the CWR main menu.
12.Select 'wipe data/factory reset' in CWR and confirm with 'yes'
13.Select 'install zip from sdcard', then select 'choose zip from sdcard', then select the zip file you want to install and confirm.
14.Wait until the Rom installation is complete, then 'select reboot system now'.
15.Your phone will reboot and be up and running! Custom Roms tend to take longer to boot so be patient.
Let me know what happens.

Are you using CM7 nightly? I think it has a USB mount bug and the google apps including market are not in the CM7 rom and have to be flashed separately from the rom.

USB Storage won't mount
The usb storage isn't showing up after I run cwm
Another restoration method you could try is using Odin to flash back to stock and retry the whole root process step by step ....I am on my phone right now so its hard for me to dig for threads but I know there are instructions and a stock Odin image floating about

yes, i can access clockwork mod also, but it the usb storage wont show up.....
Follow these instructions:
1. Slap self in head.
2. Power on phone while holding volume up&power button.
3. Now on the pc, Get the fastboot folder to the root of hard drive, I.E. C:\fastboot\. Also add to this folder your *.img files (radio, recovery, boot, system, data, etc.)
4. Open start menu.
5. In search box type cmd and press enter.
6. Now command window is open, type in that
cd C:\fastboot
fastboot flash * *.img
Replace the * with appropriate .imgs.
recovery, system, data, boot, radio.
Example
fastboot flash recovery recovery.img
7. Now that that is finished type
fastboot -w
fastboot reboot
8. Now the phone will reboot. BE PATIENT AS THIS MAY TAKE UP TO TEN MINUTES TO FULLY REBOOT INTO ANDROID!!! Disturbing it in anyway can cause corruption. I had this happen to my phone before. Literally walk away and come back in ten. Don't touch it, don't breath on it nothing. If you have any further problems either post here or PM me. Getting the .img files and fastboot is up to you. By the previous replies you should have them already.

I think I had the same problem. first you need to check if your pc has the correct driver to accept the nexus s in bootloader mode. when that is done and you have colckword mod , you can but a custom rom on the sd card and flash that, then you'll be able to use your phone again.

Can't boot in recovery, can't ADB too..

I have a little problem,
i flashed the 5.5.0.4 CWM.
My issue however, is that i can't boot in recovery. Whenever i use an app to boot in recovery and just straight boots Android. Im not experiencing the recovery boot-loop.
The other problem is that i can't use ADB either, i have the stock ICS that can't recognize a PC connection via USB.
SBK2 so NVflash is out of the question.
Help
i want to get another recovery on there and flash another rom to avoid all these issues
Which app are you using exactly? Not all of them work correctly on the tf.
Have you try using the button combo method?
Hold down Vol down plus power button till you see words at top left
Immediately push Vol up within 5 sec should take you to recovery
As for ADB, do you have correct driver install?
Did you install ASUS PC sync?

Had the same issues and installed an app called "Transformer reboot to Recovery" that worked!
Humm disregard this issue..
I wasn't pressing the VOL+ key to get in recovery.. strange because it never happened before but anyways..
should i still walk away from 5.5.0.4? Because i did some test and i have no issues with it..

I just used the SDK version ADB and Drivers to get ADB working fine. Just used it to put Revolver on.

Did I brick it?

So I successfully downgraded back to Froyo. I followed the Rooting process exactly, mdr #'s 2 and 3 matched. I entered the reboot command, and now my phone only vibrates 3-4 times when you turn it on. the led keeps flashing. and nothing is happening with the screen. I cant get it to the bootloader screen either
is it being recognized through adb?

It shows S-Off though lol. Is there any info that I can give you guys from the menus I have available in order to help decode what I did wrong/what went wrong?
Try this...Take the original 2.3.4 update and put it in your sd card.(assuming your pc detects the sd card). Take the battery out if the phone for about 10 min. try to boot into hboot and reflash the phone back to stock. Then redowngrade and root again.
Sorry if I'm not too much help. I'm learning from what I read here and there.

Hey Mike, I am having the same issue with my phone I tried the adb reboot recovery command in adb but the phone just reboots. I wanna know how did you boot into clockworkmod recovery or the bootloader. Please help me out I am trying to fix my phone. thanks
clockwork is "adb reboot recovery"
bootloader is "adb reboot bootloader"
you can only do this stuff if the device is recognized. If it just reboots when you do reboot recovery, you probably don't have it flashed correctly or don't have the right bootloader

Download PD15IMG.ZIP here, copy and paste on the root of your SD card. Don't forget to rename the files to PD15IMG.zip before you copy them to the SD Card, otherwise it won't work
Turn off your phone.(you should have enough battery charge)
Press POWER and VOL DOWN simultaneously (this will bring your boot loader)
It will automatically install the PD15IMG.ZIP, need to confirm some actions.
Wait till the process is done....
If you did not encountered any error such as FAIL- PU, you can open your phone normally and start setting it up...

Bricked....Need help

Well, I have finally done it......bricked my Transformer
Any assistance to fix my problem would be greatly appreciated.
Here is my situation:
I have a tf101 - model b90
I was running ICS rom with rogues recovery
I have been trying to fix the GPS problem for a while now and went back to stock rom unrooted to see if that would work.....it did not
In my effort to re-root my device i STUPIDLY flashed recovery with ROM Manager (and then read AFTERWARDS that was BAD, BAD, BAD)
I am now stuck in a recovery bootloop......HERE IS THE GOOD PART
I tried to flash an older ROM - Revolution 3.2
So now i have a combination of the recovery loop and when i try a cold boot it gets stuck on the Linux cold boot / android screen
i have tried to get ADB running with no success.....my computer (WIndows XP) makes the chime when i connect my transformer......i even get the message in the taskbar showing the device is trying to install drivers but it never shows up in my computer
My device does not show up when i run adb
Can get into ADX mode but my model is too new at B90 to run NFLASH
I have downloaded drivers but cant get the transformer to install them
I have tried PERI to unloop to no success - i get an adb error
What can i do to unbrick my transformer?!?!?!
Thanks in advance

Silly but start with Skip all, then no, then auto rename all, then yes, see what those do. Ensure that you have the correct zip rom from ASUS from their site, instead of trying to install a DEV ROM.
LET IT SETTLE. Often times these errors are caused by impatience. set the tab down for a while, an hour, maybe 2 when you start this whole reflash.
CWM has an issue with the TF101, if at all possible install TWRP, and work from within there.
I agree with MasterDecker, use TWRP. I had some issues with CWM. TWRP is a nicer interface anyway.
I find wheelie (from linux PC) to get me back from any situation. The steps are not easy at first. I had to download the stock blob, unpack the blob and then use reflash_sbkv1.sh to flash it through USB cable in APX mode.
Even if you don't linux, you could download a free Ubuntu livecd from ubuntu.com, boot off the cd and use wheelie without installing ubuntu linux. Or just about any other linux distro fro that matter.

[Q]Can't mount tablet as USB Storage Device, ums lunfiles issue

Hello folks,
To start, the tablet is an a500. It's running the ICS bootloader V8 with Thor's 1.7.3 recovery.
On my Nexus S, I was able to mount the device as USB mass storage from the recovery, drop a new rom on it from the computer and flash as usual. I can't do that with the a500 because it gives me the "Unable to write to ums lunfile" error. Thinking back, the recovery has always given me this error, but I've gotten around it by successfully mounting it from the booted tablet instead of from the recovery - I can't do that this time because booting hangs on the Tegra Owners screen and doesn't continue any further.
Things I'm wondering about
-Am I on the right recovery for the V8 bootloader? this indicates that I should switch to this
-Can someone point me to how to properly flash recoveries/roms via adb/fastboot?
-What can I do to be able to mount the a500 through the recovery?
I've tried to do some more research and I think my data might be pooched again. A few posts mentioned that formatting the data enabled them to mount their tablet as a USB device to load roms onto it. When I was still running the HC bootloader, I was able to successfully format the data using the hardware reset (power, volume+, screen lock). I'm trying to do that again, but it just boots straight into the V8 bootloader.
1) rotate lock set to the locked position
2) hold volume+

Hello folks,
To start, the tablet is an a500. It's running the ICS bootloader V8 with Thor's 1.7.3 recovery.
On my Nexus S, I was able to mount the device as USB mass storage from the recovery, drop a new rom on it from the computer and flash as usual. I can't do that with the a500 because it gives me the "Unable to write to ums lunfile" error. Thinking back, the recovery has always given me this error, but I've gotten around it by successfully mounting it from the booted tablet instead of from the recovery - I can't do that this time because booting hangs on the Tegra Owners screen and doesn't continue any further.
Things I'm wondering about
-Am I on the right recovery for the V8 bootloader? this indicates that I should switch to this
-Can someone point me to how to properly flash recoveries/roms via adb/fastboot?
-What can I do to be able to mount the a500 through the recovery?
I've tried to do some more research and I think my data might be pooched again. A few posts mentioned that formatting the data enabled them to mount their tablet as a USB device to load roms onto it. When I was still running the HC bootloader, I was able to successfully format the data using the hardware reset (power, volume+, screen lock). I'm trying to do that again, but it just boots straight into the V8 bootloader.
1) rotate lock set to the locked position
2) hold volume+
3) hold power until tablet vibrates, then release power and switch the rotate lock to the unlocked position

Hard reset will not work this way on v8, u need to use fastboot...
Boot to fastboot pwr/vol UP
Connect to pc via micro USB cable
Open cmd prompt type:
fastboot devices
U should see a ?
Type:
fastboot erase userdata
fastboot erase cache
fastboot reboot
It might pay to reflash your recovery while you're there
Grab your chosen recovery
(I used cwm1.7.3 that came in civatos nvflash v8 pckge and renamed it recovery.img)
and copy it to the fastboot folder
Fastboot erase recovery
Fastboot flash recovery recovery.img
Fastboot reboot
Yes, v8/cwm 1.7.3 should work fine, not sure why u have errors mounting....someone else maybe able to help with that...
good luck

This is a super helpful post. Many thanks!
I'll try this in the next couple of days and report back.
Hello Dibb, thanks again for trying to help.
Using fastboot, I successfully:
-erased user data
-erased cache
-erased recovery
-reflashed the 1.7.3 recovery.
I didn't have any luck mounting the tablet in windows, so I tried the above steps again, but this time flashing the TWRP 2.1.3.
The recovery booted OK, so I know I did that correctly, but still no luck mounting.
Next, I tried redoing the bootloader/recovery using Blackthund3r's A500 APX Flashing utility back to the Bundle 17 (A500 and A501 BL v8 / Thor Recovery 1.7.3, ICS Unlocked / Skrilax Bootloader v8 and Thor Recovery 1.7.3 for the A500 and A501) to maybe get a fresh start. I rebooted into the recovery, but still no luck mounting the tablet.
I think I need to try pushing a rom straight onto the tablet using either fastboot or adb, but I'm not sure how to do it. I did some research and came up with the following cmd code:
fastboot flash boot boot.img
All of the roms that I've ever downloaded come in zips that you flash straight from the recovery, they're not .img files. Is there a way to push zips onto the SD card using adb/fastboot? I see a boot.img inside these zips, but I feel that if I flash that after extracting it from the rom zip, I'm not going to be getting any gapps or any of the other potentially important stuff in that zip. Do you mind explaining that, and maybe including some more awesome instructions on how to push a rom onto the tablet from windows, without having to mount the SD?
Thanks in advance!
K, lets back up a bit.....a quick question first
Are u just wanting to flash a custom rom via recovery?
As long as you have the unlocked bootloader (which you do) just flash via "install from zip" option from either
internal or external storage.....or am I missing something?

Yep, that`s exactly what I want to do.
My problem is that there's nothing on the internal disk (I have no SD card for the a500) and I can't put anything on the SD card because it won't mount to show up in windows for me to drag a zip onto it.
Roger that then
And no card reader either I take it?
Edit: what rom are u running right now
That's right, no card reader either. I do have a USB key, maybe I can put a new rom on that and mount the usb key in recovery?
I'm not sure what rom I'm on right now, it's been so long since the tablet successfully booted into a rom. The last one I think was Thor's JB v17 from tegraowners.
Yeh try the USB key first....
I didn't realise you couldn't boot your OS, thought you meant the recovery screen, no matter...
do you have your cpuid backed up somewhere....anywhere....pleeeaasssee say you do!!!
I'm just writing up a post now in case the USB key won't work...
Yep, I've got the CPUID, drivers, sdk, adb and fastboot work too.
I'm going to try the USB key method.

Awsum that's great:highfive::good:
adb push name-of-your-rom.zip /sdcard
I'm sure you will still need to mount it tho but this is not my speciality.....
If the key won't mount I'd strongly suggest you download timmydeans v4 - it does not require an sdcard. http://www.mediafire.com/download.php?fo4wqjeald4s3rj
This will downgrade you back to stock HC3.2.1 which is pre-rooted and comes with cwm....this will wipe everything and reset yr tab, that will deal with yr boot issue - and hopefully the mount issues too....
Holy**** the USB key worked, just installed CM10-FLEX_V6Supercharged_Rev2.3c.
Lets hope I don't have any SOD issues, which is what led me to upgrading my bootloader, which is what started all of this!
I searched the rom that you have in your sig, (I suppose you think it's pretty stable?), but I didn't manage to find it. Throw a link? Does it come with a kernel?
Thanks so much!!
Phew!!
Ive been using the v6 supercharge cm10 JB rom for a week or so and its fantastic http://forum.xda-developers.com/showthread.php?t=1935582
The one in my sig is ics but u know us tinkerers we have to have the latest and greatest.lol...
I never go too far from civato's roms - I'm a big fan! So can't offer feedback for anything else....
You should have no probs with SOD...mainly an issue with hc bootloader/ics rom and not wiping....thing of the past these days!
Well I'm pleased you got sorted without too many probs - happy tabbing
