Having problems with installing recovery - Transformer TF300T Q&A, Help & Troubleshooting

I have finally been able to unlock my TF300T!!!!! But now I'm trying install TWRP or CWM so I can root and I'm having a few problems...
I've been trying this guide ( http://forum.xda-developers.com/showthread.php?t=1845377 ) and I'm stuck on Part 3 step 3.
The command prompt is reading :
C:\tf300tsoftware>adb reboot bootloader
error: device not found
Then when I just plug in the tablet I can transfer any files from my pc to the table, but it will not read anything on the command prompt. Any help would be great. I've re-installed the drivers, and re-installed all of the software many times but I'm just at a loss.
Thanks again.

This sounds like you are trying to run adb, before plugging in your tablet?
Using adb generally requires your tablet to be plugged into the USB port of your PC.
Anyhow, another way to get into the boot loader is to hold the volume-down key, while switching on the tablet.
Hope that helps.

Need to know if you have the proper device drivers. You can transfer files from PC to tablet because that uses different drivers.
What happens when you type 'fastboot devices'?

You can accomplish part 3 step 3 without adb. Power tablet off. Power on by holding power and down volume till you see the bootloader menu, release both power button and down volume. Now continue with part 3 step 4.
Good Luck!

I am having the same problem. I connect the tablet and it seems to connect fine (MTP) but adb doesn't see it. When I enter the command above it just returns the next line with no results.
I loaded the Asus sync from their website which doesn't seem to have made much difference either.

[Q] Am i bricked ?

Hi All,
i rooted my phone using what i thought was the right img file, but i can only assume it was the wrong file as i can now do nothing, i can boot into the Moto symbol, i can get to the droid with the warning triangle and into the fastboot section but i can no longer detect it when connected to the usb...
can anyone suggest a fix or am i screwed ??
thanks for any help
Try reflashing it with my tool, using unbrick feature, maybe you need fastboot drivers, just download it from sdk

cheers xxlordxx
ill give that a go, which drivers do i need to install for the fastboot ?
i downloaded the google usb driver package via the SDK last time, but it seems they are not firing up when i connect the tab.

If you can boot, you are not bricked - just start over with the root process using the correct image.
hey guys,
i have downloaded LAIOT but im not sure its detecting the pad, currently im getting
Searching For Device
List Of Devices
(Nothing listed)
on the pad
Starting Fastboot Protocol Support
tried doing the same using the different modes.
on Pad
Starting RSD Protocol Support
Same result on LAIOT
Recovery -
Same result.
this has all been done on a windows 7 laptop,
i have a linux laptop, will i get any more success using that with the google driver ?
just had a brain wave, checked device manager - i have an unknown device detected.. thats where the sodding thing has been hiding...
any ideas what drivers i need to get the dam thing detected correectly ?
just going to try using the default google ones from the SDK.

Try a diff USB cable - download drivers from MOTOROLA website get this file - MotoHelper_2.1.32_Driver_5.4.0.exe
Okay here we go....
first thing let your xoom stuck on M logo.
Then hold power+volume up.
while power up press volume down to get firstboot.(make sure your PC and xoom know each other.)
You will see some text firstboot bla bla bla on left, top of screen.
Second thing open window cmd.exe
then type ...
cd /AndroidSDK/tools (where ever your adb.exe is located)
fastboot flash boot boot.img (the right boot image)
fastboot flash system system.img
fastboot erase cache
fastboot reboot
wait for reboot. You should see splash screen and you smile on your face.

hopefully ill have more joy, ill let ya know how i get on 8)
What about using RDS?

Glad you got it going!
Had a similar problem where I had a boot loop and adb didn't recognise my device, but I could still put it into fastboot or recovery with power + vol down.
What I did was boot the Xoom so that it was stuck at the Moto logo, connected to the PC and queued up the fastboot command (fastboot flash boot boot.img) so the command window said "Waiting for device...", then reset the Xoom and manually put it into fastboot again at which point it picked up the queued command and started flashing.

[Q] Issues With Rooting

I used to have a rooted EVO 4G through work, but recently they switched me over to an iSheep, and as you can imagine I absolutely hate it. And since it’s for work they’ve installed AirWatch so I can’t jailbreak it. But I also have a TF101 that's currently not rooted.
I got my TF101 about a year ago and rooted it like every good android user should. But after about 6 months, I found a small hair line crack in the touch screen. I unrooted it and sent it in to ASUS for them to repair. I always keep my tablet closed in the docking station when it wasn’t in use. I then found this thread, http://forum.xda-developers.com/showthread.php?t=1498237 that stated this is why the screen cracked. So ASUS and I went back and forth for about a month before they finally covered it under warranty and repaired my tablet.
When I got my tablet back I found they upgraded it to 9.2.1.27. I connected it to a computer so I could reroot it, but my tablet is no longer detected by a computer. I tried two computers and two data cables. I’ve also tried all the methods for installing the drivers. I didn’t want to send it back to ASUS due to the issues I previously had with them. I’ve been following Thing O Doom’s thread, http://forum.xda-developers.com/showthread.php?t=1681155 because he stated he's working on a rooting apk, but he no longer has his TF101 so progress has been slow.
But in my searching I found this thread,http://www.transformerforums.com/fo...rmed-fix-gain-root-after-8-6-5-21-update.html that stated I can get the zip out of an old ASUS update and put that on my sdcard and let the tablet update itself to an older version. ASUS made an instruction sheet for manually updating with a zip, http://dlcdnet.asus.com/pub/ASUS/EeePAD/TF101G/e6754_TF101_Update_SOP.pdf. Once downgraded I could use RazerClaw http://forum.xda-developers.com/showthread.php?t=1345049 to root, and then flash a recovery, rom, etc.
Will this method work? I have to believe no, it just seems too easy. I haven’t tried it yet because I worried about bricking my tablet and not being able to fix it since it won’t connect to a computer.
Any response, opinion, recommendation, experience would be greatly appreciated.
I am not sure that will work. It worked when you had 8.6.5.X because it was upgrading to a "newer" version that is 8.6.6.X (for the TF101G).
Now you are on a 9.X, so it most likely will not work.
Have you tried APX mode? I used that to root from the .27 firmware without having to downgrade. Turn off your tablet, hold VOL UP and then press the POWER button for about 3 seconds. The screen will be black, but when you plug it into a computer it should be detected.
If it does work, use EasyFlasher and install a custom recovery (HIGHLY recommend TWRP over CWM).

Thanks for the reply. I did try APX mode but I would get a message on both computers I tried stating the device was unrecognizable. I then tried to load the drivers but it still didn't work on either computer.
I guess you could try the other method. Since it is using stock recovery there is very little chance of bricking IMO. It will either install the older firmware, or it will not.

air adb, there's at least 1 good free one in the play store.

Just curious, did you reboot your PC after you installed/uninstalled the drivers?
I had this same problem once. What I did was pulled up Device Mgr and checked for APX drivers. If there was some, I uninstalled and Rebooted the PC. I downloaded these Universal Naked Drivers and saved them where I knew where they would be. I left the Device Mgr open and booted into APX mode. It asked to install drivers. I said yes and it failed. I then pointed it to the Naked Drivers and and it found them pretty easily. Once I saw APX pop up in Device Mgr, I was good to go. I then used EasyFlasher to flash back to .27 with Root. The link in the EasyFlasher OP for stock firmware is off for some reason. I posted the direct link near the last pages. Here it is.

You don't /need/ adb to root it this way, all you need is a terminal interface on your tablet. If you can download and unpack the zip file containing the blob for whatever recovery you wanna use, then link the mmcblk0p4 to tmp, you should be able to be good to go after a dd and reboot.
--edit--
start here: Instructions - Method 2 - UnRooted
then replace step two with "download terminal emulator from the play store"
then replace step three with 'open terminal emulator'
continue with the rest of the tut, using whatever recovery you want (i use Rogue XM)

I tried this and you're right it didn't install the older firmware. It looked like it was going to because the status bar was moving at the bottom, but after a few minutes it went to an android laying down with his guts open and a exclamation mark above him.

I think I've tried this. I have a terminal emulator installed and I followed some instructions about entering things like this in but I think I got a message stating access denied. But I'll try it again tonight and reply back with the results.
Re: [Q] Possible Downgrade to Root
Using wolf's instructions I tried this with a terminal app on my tablet and got the following.
[email protected]:/ $ mv /data/local/tmp /data/local/tmp.bak
failed on '/data/local/tmp' - Permission denied
I then tried this and got the following.

This weekend I tried to install the drivers again. I first went through the control panel and device manager and deleted anything that said android and asus, then rebooted my computer. I then tried to install PDANet because I read that it'll install the drivers needed and if you're having a problem it's an easy way to install them. During the PDANet install it told me to plug my transformer in to load the drivers. When I did it said it was installing new drivers but then it said they didn't install. My transformer came up as an unknown device in device manager.
I then went through and deleted the unknown device and checked in the control panel again, then rebooted my computer. I then put my tablet in APX mode to try and get it to load the drivers. Again it didn't install them and my transformer came up as an unknown device. I deleted the unknown device agian, rebooted, and went to ASUS website and installed ASUS Sync. When it finished I rebooted and then started ASUS Sync. Again when I connected my transformer to my computer it said it was loading the drivers, then it failed, and the computer showed my transformer as an unknown device. ASUS Sync also stated there was no device connected to it.
All the reading I've been doing, it seems like there are some other people experiencing the same issues I am, and I haven't seen where anybody has posted a solution. If anybody has any input please let me know.
I think I'm getting closer. I downloaded WLanAdb from the play store and followed the directions and downloaded the needed files to my computer. In the command prompt I type "WLanAdbTerminal devices" and my tablet will show in the list of devices. But WLanAdb is only setup to except a few commands, the main purpose of the app is for pushing files. It was the only wireless ADB app that I could find that didn't require root.
I then found SSHDroid in the play market and I downloaded putty to my computer. I connect to my computer using that. When I type "adb devices" I get a mesage that states
daemon not running. starting it now on port 5038
daemon started successfully
List of devices attached
I then left putty and went back to the command prompt and typed "adb connect (with my ip address and port from SSHDroid)" and it said it connected to that ip address and port. I then type "adb devices" and there are no devices listed.
Again I think I'm very close to getting my tablet connected wirelessly to adb. I think there is just one simply thing I'm missing. Any help would be greatly appreciated.
I'll continue to update this thread until my tablet is rooted or I reach a dead end, so this will be a reference for anybody experiencing the same issues as me.
Thanks in advance.

I haven't. I'm now trying to make a Linux boot flash drive to see if I can get my tablet to connect that way, since I've read that Linux doesn't require drivers. I downloaded LinuxLive USB Creator but haven't had the time to try it yet.

Another Bricked TF300

Hi, good people. I have bought a TF300T bricked last week, the old user has stock OS, tried to root and failed.
Now im fighting with that. When i turn on the tablet, it stuck at 'The Device is Unlocked' with Asus n' Nvidia Logo, after a minutes it reset and keeps in a constant loop.
I tried to recovery [vol down etc etc] and no effect, i tried with a few of tutorial and nothing.
I connected the tablet via APX [VOL UP + power]. PC recognized it but i stucked in this. Tried to fastboot and stays in 'waiting device'
Someone with ideas? Thanks frr all and sorry for the inconvenience.

PC operating system?
Drivers for fastboot and adb loaded?
Look at my signature about universal naked drivers.
Also about getting into your bootloader menu.
APX will be useless to restore.

I'll assume that means all ten methods to get into the bootloader failed.
If the adb drivers installed we may have a chance.
You didn't say about the sdcard.
At the moment are you still stuck in apx or bootlooping.
Sorry but I need a place to begin.

No problem we just need to get a starting place and have as much in our favor as possible.
I don't believe adb works in apx mode but we'll give it a shot.
No sdcards come with the tablet.
Go into apx mode (volume + power).
Go to your adb folder with cmd and type
adb devices - press return or enter
If it is working we should get your serial number in return.
Now get out of apx mode.
type
adb devices - do not press return yet
watch your unit and when the screen goes black and before it lights(rebooting) now press return
Tell me what is returned each way.

Without adb or fastboot access I don't know of anything else to be done.
If you could have gotten into the bootloader menu we would have had a chance.
Maybe someone else will read this thread and have more ideas.

same problem here. i have a tf300t and can only access apx interface.
I got into this mess, after by "accident" choosed the "wipe data" option present on the bootleader.
!! adb, fast boot do not work!! "power key + down button" dont do anything!
i'm getting a bit resteless because no matter were i search on the web i can not find anything suitable on how to resolve this issue...
there are some youtube videos that show a solution for tf100. it seems the same problem.

there is also a tool for tf100, called easy flasher. to bad it does not work for tf300t

Do you see anything after resetting by holding volume down and the power button? If you can get the tablet into fastboot mode you may able to revive it. If you can, ask the previous owner which version stock Android he was running before he tried to root it (it matters!).
This method worked for me!

USB not recognized + no Recovery

Hi All,
It has been a time that I unlocked my TF700t then followed the CM10 documentation to install 10.0 using CWM.
Recently I wanted to upgrade to 10.1 but it didn't work and ended with my tablet rebooting undefinitely.
I reverted then to install back the ASUS stock Rom from their website :
- I downloaded the file
- unzipped it (since it contains another zip)
- put it on a micro SD
- Booted into CWM
- installed the zip
I ended with a working tablet on the stock rom JB 4.1 but know I wanted to try again CM but I cannot access recovery anymore. I can access the bootloader but when I select RCK I get the droid laying on his back with the warning sign.
I thought I would need to flash another recovery (TWRP or other) using fastboot but now when I plug the tablet to my PC it keeps telling me that the device is not recognized. I tried to install the USB driver but it doesn't get detected.
Can anyone please help ? The tablet is working but I am afraid that it has lost some of its capabilities.
Thanks

- Booted into CWM

I ended with a working tablet on the stock rom JB 4.1 but know I wanted to try again CM but I cannot access recovery anymore. I can access the bootloader but when I select RCK I get the droid laying on his back with the warning sign.
I thought I would need to flash another recovery (TWRP or other) using fastboot but now when I plug the tablet to my PC it keeps telling me that the device is not recognized. I tried to install the USB driver but it doesn't get detected.
Can anyone please help ? The tablet is working but I am afraid that it has lost some of its capabilities.
Thanks

Go to your system setting and select storage. Click the 3 dots in the upper right corner and tick the box which is Media device (MTP).. Good luck..

What Windows version are you running?
You may have to uninstall the drivers for your MTP device before installing new ones as well as disabling Windows to automatically install drivers for a new device, then manually point it to the Universal Naked Drivers folder.
Or downlaod Android SDK tool ad through it the Platform Tools and USB drivers.
BTW: When you flashed the stock firmware you lost your custom recovery. That's why you see the dead Droid - it's the stock recovery.
If you can't get fastboot to work you can use Motochopper to root your JB 4.1 stock firmware and then GooManager to install the latest TWRP recovery.

I have tested it on WinXP, Win7, Ubuntu and another box with Win XP. Always same thing the device is not recognized.
When I try to update the driver and point it manually to the naked drivers it cannot detect them.
I guess that even for running Motochopper I will need to get USB working to be able to root my device.
Any help please ? I am stuck with a sluggish stock mod that buries the perfs of my device.

You do have USB debugging enabled in the Developer settings, do you?

Then it's a driver problem and it's solvable. What do you see in Device Manager under Portable Devices with your tablet connected? Did you uninstall the driver and re-install it?
Did you try to install Asus Sync (which should give you compatible drivers for the TF700)?
So many driver problems lately... there's got to be a pattern to it, but what it may be beats me :what:

In the Device Manager I have nothing under Portable Devices, but under USB devices it appears an Unrecognized USB Device and a bubble notifying about an unrecognized USB device keeps popping in the task bar. Even after installing ASUS Sync it is not detected.

You don't connect your tablet to the PC through the dock USB port, do you?? Just had that in another thread....
If you connect the tablet directly, I'm stumped. No idea why it's not recognized...

I don't have a dock and I am connecting directly with the cable. I have just reflashed it to stock rom again hoping it resolves itself but nothing.
It's driving me crazy. The stock rom is really sluggish and I want to flash it to CM
Sounds like a windows driver issue to me. You need to force windows to use the right usb drivers. You normally do this by upgrading thenm in device manager. You may have a borked windows installation to fix as well..
Try the ones I have attached.

I have tried different windows installations with the different drivers that you provided me, still nothing. It seems to me that the device is not even sending proper ids to the system. Can it be caused by a damaged cable ?

Had the same problem.I fixed it by uninstalling the faulty usb device. Then disconnected the usb cable. Reconnected. And the drivers installed.

Im having the same problem and after one day of research I could not find a solution. I bought a use TF700 with a standard andriod on it, no mod, not unlocked, no root. When I connect it to the pc I get the same error, meaning just a USB Device showing up. Tried different PC's with different types of OS, no success.
Did you manage to fix the problem ? I would really appreciate some help because now I can't use that tablet in debug mode to test my android applications and that's all I bought it for. By the way, is there a adb tool that works wireless and doesn't neet root access or can I get root access without connecting my pad to my pc ?
Thanks for the help !
Well did you install adb fastboot drivers on the PCs you tried? Did you try it under Linux? Do you have the original Asus cable you connect it with?
adb over network is an option under Developer Options in Omni and Omni based roms - at least the LP roms. I don't think you can get that with an app you install. Probably needs to be baked into the kernel.

First of all thanks a lot for your response, didn't think anyone would still react on that post because it's quite old. Yes I did install adb fastboot drivers, the device only shows up in the usb section saying usb device not recognized. I tried nearly every driver I found, installed the Andriod SDK, the Asus Sync Tool, the naked drivers... then removed them all (including the hidden ones) and installed just the adb fastboot -> no success. I have not tried it on linux, but on windows 7, 8 and 10. Android version is 4.2.1 and Build is 10.6.1.14.10. I now unlocked it using the apk provided by asus (version 7 , 8 did not work). Still for rooting I need pc connection, so I ordered a new cable today (cable is original Asus though).
I installed the Rom Manager and that tells me the ClockworkMod Recovery and TWRP are already installed. I also tried that recovery (power + vol) and got the same result as nacef meaning " I can access the bootloader but when I select RCK I get the droid laying on his back with the warning sign." Thing is, I don't know what the previews owner did, so it might be the reason he sold the Tablet. Can I get anywhere form that Bootloader ? Maybe boot as a Superuser and then use wireless adb to root the device ?
Thanks a lot for your help, Im feeling that I have wasted the money and the only way to get rid of that feeling is to fix the problem
Grab the Puppy Linux live CD from here: http://www.transformerforums.com/fo...t/46090-guide-adb-fastboot-linux-live-cd.html
It has adb fastboot already installed. If you don't get a connection with that one the problem would be tablet side, not Windows related.
I booted using that Puppy Linux and followed the Guide but no success. After entering "adb devices" I get the output "list of adb devices attached" and than a blank space. So I tried booting in fastboot like you described in your guide and entered "fastboot devices" but that also gives me nothing. Fastboot works though (as it's already included in that image) so I tried a bunch of other fastboot commands but that just results in "waiting for the device".
I don't know what to do now, it has something to do with the tablet itself. Im waiting for the new cable but don't think thats gonna change anything.
You are not trying to do this through the dock port, right? You are connecting the tablet directly to the PC?
The only answer I have left is either a broken cable or one of the pins in the port is bent or broken. Get a magnifying glass and check them out.

[Q] Computer will not see tf300t in fastboot

hey i've tried searching the forum and couldn't find anything the helped.
i'm trying to load a custom ROM on my transformer but i can not get my computer to recognize my tablet in fastboot
i have already unlocked the device. i can get the bootloader menu on the tablet but when it's connected to my computer and i go into cmd i will type fastboot devices and it doesn't see anything it just goes straight to the next prompt.
i'd tried reloading the drivers and this has not worked either.
any ideas?

Try using a different USB port or cable. What does the device show up as in device manager on your computer?

Are you using the full Android SDK for fastboot or one of the minimal versions? You may want to try a minimal version to get a fresh install of fastboot. http://forum.xda-developers.com/showthread.php?t=2317790

Yeah you may want to give that minimal a reinstall or install a newer version of it.
