Thanks for the great info! However, I can't get into it to verify what software it has at all. In that case what would I do?

Also, where do I download the firmware? Sorry for all the questions, trying to wrap my head around all this and a the stuff I've been reading in search is all about modified software/roms. Not a lot of information on stock stuff that I could find.
[Transformer TF300T General] tobdaryl:
Here is a link for downloading the firmware and most other things you may need to download or references to things you might need to know. Look through at least the first three posts.

[INDEX]13 Mar 2013 - TF300T/TG WITH ALL ASUS ORIGINAL TOOLS-Firmwares-Kernels-Guides

Not knowing what firmware is in each unit I believe I'd try 10.4.2.20 as my base line. That is the newest JB (4.1) firmware.

Note: The firmware numbers I have used relate to TF300T units and US skus.

The methods I gave for updating firmware all assume stock recovery is installed which is the best place to start.

Note 2: If you are unable to get into the os the only method above that is useful is the last.

If the above fails download the firmware and unzip once as above. Name the resulting zip EP201_768_SDUPDATE.zip and place on internal sdcard and follow the above directions. If that fails power tablet off, power on while holding power and volume down -when the icons appear press volume up while on the RCK icon - stock recovery should take over and accept the update.

Holding power and volume down is a attempt to get into the bootloader (apx is useless). See my signature for a link about getting into the bootloader.

If you don't have drivers properly loaded for this tablet and you are on windows see my signature for a link to get them properly loaded.
[Transformer TF300T General] kmad86:
Wow, I really appreciate this! I'm going to check it over.
[Transformer TF300T General] tobdaryl:
Reread my last post as I added some useful info.

We were overlapping posts and I see I had not finished typing when you responded.

I'll be offline for an hour or two but I'll check later.
[Transformer TF300T General] kmad86:
none of the links work for me. they bring me back to the main forum.
[Transformer TF300T General] kmad86:
Ok, so I tried the Power+down with the SD card and the zip file on one that had no touch at all. IT WORKED!

At first I thought it was messed up and it froze on the android on it's back with the red triangle. I reset it after 5 minutes and it went to ASUS with a blue progress bar and then worked.

One problem fixed!
[Transformer TF300T General] tobdaryl:
Note 2: You need to think about getting adb and fastboot working properly.

adb can be accessed when powered on and just sitting there

and when booted into cwm or twrp

fastboot get into the bootloader (power and volume down) press volume down to choose the usb icon then volume up to select - this would be on the 4.0 and 4.1 bootloader - if you have the 4.2 bootloader there is no usb icon and the tablet if left will auto turn on fastboot (look in upper left for the message) (DO NOT USE WIPE DATA IN THE BOOTLOADER)

test if adb is working by typing

adb devices

test if fastboot is working by typing

fastboot devices

each will return the unit serial number or all zeros when working

I'm sorry to do a piece at a time but there are so many options etc

Searching

go to general (example) without choosing a thread look in the upper right for search to the right of this there is a gear select that (advanced search) - in search by keyword type mismatch (example) - scroll to the bottom and click search.

This example searches all general threads and all posts within these threads.
[Transformer TF300T General] kmad86:
a piece at a time is fine for me. I'm learning! I really do appreciate the help.

I don't have any software downloaded but the ASUS sync program. I need to download cwp and twrp as now I am realizing those are programs.

I tried the same MicroSD trick on another tablet with touch problems, and it went through the process but booted back to a really weird screen and I still have no touch.

Picture of Screen
[Transformer TF300T General] tobdaryl:
That's an interesting screen I have never seen. I don't know what it is but may be useful.

I forgot to cover something in my last post.

The android lying on his back is stock recovery with no file to process. We need to get adb and fastboot working properly. We can use adb to push our file to the internal sdcard and let stock recovery process it for us.

Tell me about your pc! Windows 7, 8, linux, mac?
[Transformer TF300T General] kmad86:
I have a windows 7 laptop that I can use. I am primarily mac but I know Windows is best for these.

I just tried another, and got the same screen as above with no touch.
[Transformer TF300T General] tobdaryl:
Good choice!

Read your pm and let me know what I have forgotten or anything you don't understand.

For the moment let's use the tablet you began with and finish the thread for any who are watching or come later. We'll need to consider another communication vehicle for the remainder.
[Transformer TF300T General] kmad86:
In my years of computer experiences, usually my friends come to me to help them out. With this, I am so lost and feel so hopeless as I am starting to understand how they feel most of the time.

Anyhow. I am really lost with the CWM and TWRP thing. CWM seems to need to be installed through the tablet in the android store and runs on it? TWRP also seems to need installed on the tablet and used on it. I was assuming I would install something on the windows computer that communicates with the tablet to get it going. I think that's why I am so off track here.

When you say type "adb devices" to verify it's working. Where am I typing that? In the SDK kit somewhere?
[Transformer TF300T General] tobdaryl:
Sorry that is one I missed. Forget CWM. Both CWM and Twrp are custom recoveries used to replace stock recovery. They can be used to flash stock rom or custom rom, root, and etc.

Let's stick with the this thread for now as we are overlapping. Go to android-sdk/tools and run android.bat. Install Android SDK Platform-tools. This will add the android-sdk/platform-tools directory and inside you will find adb and fastboot. They should be run as administrator with cmd (terminal - cmd - command prompt).
[Transformer TF300T General] kmad86:
One more thing, is all of this for signature mismatch, or the no touch ones?

:) I'm slowly grasping this!
[Transformer TF300T General] tobdaryl:
No but they are sometimes harder(much harder). We should divide them into groups and work with a group at a time. Trying to overlap them may result in hard bricking a unit when the situation is different and may require a different technique.

All of them will probably require adb and or fastboot.

With adb working we might be able to push the file you used earlier to your internal sdcard and get asus recovery to fix the unit by reinstalling the full stock firmware. Of course that would be the easiest outcome.
[Transformer TF300T General] kmad86:
Wow, this is fun and nerveracking at the same time! Ha.

Ok so I assume in Command I need to type something to actually get it linked to the tablet.

My android SDK Path is : C:\users\admin\desktop\tf300t stuff\adt bundle\sdk (if that helps)

Right now on Command Terminal I am looking at:

C:\users\admin>

15 years ago, I could navigate through command, anymore I am lost. I need a brush up. I think what I am needing to do is get it to point to that SDK path.Right?
[Transformer TF300T General] tobdaryl:
Command prompt admin will normally drop you in c:\Windows\system32.

cd \users\admin\desktop\tf300t stuff\adt bundle\sdk\platform-tools - this should work as long as you are on the proper drive and I'm reading your path correctly.

adb and fastboot are located in platform-tools - if platform-tools does not exist you missed the step where you run android.bat.

Don't worry I'm still trying to remember the / has to be \ in windows path.

I don't think it will but if this fails you may need to remove the spaces in your path (from the 8086 days).
[Transformer TF300T General] kmad86:
I got that part finally, I don't know how and I wish I did but I just copied and pasted the path you gave me and it auto corrected it I guess.

Anyhow, I ran adb devices and it says

* daemon not running. starting it now on port 5037 *

*daemon started successfully *

list of devices attached

C40KCT038725 device

Then, I typed in fastboot device.. and it's booting into it fine. It gives me some options and commands to choose.

(I'm testing this all on the device that I put the SD card in, and it ended up fixing the touch the first time it installed it. I just figured it wouldn't hurt to test it all on a working unit while my signature mismatch problem is charging.)
[Transformer TF300T General] tobdaryl:
Good! Remove the serial number(safety).

For fastboot to work you need to get into the bootloader. I described the process earlier but if necessary I'll try again.

Check fastboot first and then we'll push your zip to your internal sdcard and give recovery(stock) a chance.

adb push EP201_768_SDUPDATE.zip /sdcard/EP201_768_SDUPDATE.zip

this assumes your zip is in the platform-tools directory with adb and fastboot.

from power off - boot into recovery - power and volume down when you get the menu volume up to select RCK.
[Transformer TF300T General] kmad86:
Ok, so I got the signature mismatch tablet charged and turned it on while holding power and down. It booted and said it's "Push volume up" which I did. From there, the screen is now just blank but the backlight is glowing.

I got into command and ran fastboot device and it's hung on waiting for device.

If I boot it back on, it tells me "Signature Mismatch, Unrecoverable Bootloader error 00x00000" and then in a few seconds goes to a dark screen with the black backlight.

edit:

I took the SD card out and put it back in. It boots Signature Match. Then shuts off and back on and says the signatue mismatch, unrecoverable bootloader error
[Transformer TF300T General] tobdaryl:
That unit appears to have no recovery and a bootloader mismatch. It could have a JB(4.1) bootloader and JB(4.2)os or....

Fastboot is on the same menu but you press volume down to move through the choices until you are over the usb symbol and then volume up. Or if the bootloader is 4.2 there will not be a usb icon and you just wait ten seconds and see fastboot started in the upper left.
[Transformer TF300T General] kmad86:
There isn't a USB icon thus making me think maybe it's 4.2. I assume I should go back now and download the .zip tailored to 4.2 and put it on a MicroSD and then hold power+down and run RDK.
[Transformer TF300T General] tobdaryl:
Of course you can try. If we have a recovery it appears to not be functional(it should have reared it's ugly head when we chose RCK earlier). Go back to the bootloader menu and let it sit without touching any buttons, in ten seconds you should see entering fastboot in the upper left(if this is the 4.2 bootloader). We haven't discussed ICS and may not but that is another bootloader menu.

What happened to the other unit we were working with in the beginning? The one with stock recovery.

You should start to see why no one thing will fix them all.
[Transformer TF300T General] kmad86:
Two things.

One, when I hold power and volume down it prompts me with the two icons. I let it run 10 seconds after the icons pop up and it just resets. It doesn't go into a fastboot mode.

Second thing, I just noticed that my MicroSD card is labeled (for 4.2) TF300T_US_epaduser_10_6_1_8_Sdupdate.zip should this file be renamed to something else to recognize?

Although little, I feel like I am gaining some ground finally!
[Transformer TF300T General] tobdaryl:
One sounds like locked ICS. The ICS bootloader does not display the usb icon until unlocked.

Two you need to unzip that file once and your new zip will be named EP201_768_SDUPDATE.zip. If stock recovery is in place it should deny flashing if my info is correct. Why? The EP201_768_SDUPDATE.zip includes an assert in updater-script to deny installation except from JB 10.4.2.20. Another thing to consider here is the first JB (10.4.2.9) repartitioned the drive (mmcblk0) for the JB system and the following updates.

At the very least you are gaining knowledge which is a positive direction. Considering what you have on your plate everything you can learn is positive.
[Transformer TF300T General] kmad86:
If it is 4.1, it wouldn't have just two icons, right?

I'm asking because If it is 4.2 I figure the 4.2 sdcard won't hurt to try.

So is my move now to get it to JB 10.4.2.20?
[Transformer TF300T General] tobdaryl:
JB(4.1) has four icons. Since this unit has the bootloader signature error it probably is a mix of ICS and JB or a mix of JB(4.1) and JB(4.2). Two icons makes me think of ICS.

You can try, as I said there is an assert that should stop the update if my guess is correct. I'm not guessing about the assert as I just verified as being correct. I'm guessing about ICS and JB being the mix.
[Transformer TF300T General] kmad86:
Yeah, nothing. Didnt work.
[Transformer TF300T General] tobdaryl:
I need to verify no fastboot on this one and blank screen when we tried to get into recovery (volume up on RCK).

If adb works try this command and see if we can enter recovery by another path.

adb reboot recovery
[Transformer TF300T General] kmad86:
When I do that, I keep the sd card out, right?

Says : "error device not found"
[Transformer TF300T General] tobdaryl:
I don't think it will matter but try with it in for fun. If you can get into recovery we'll use this path and push our file to the internal sdcard.
[Transformer TF300T General] kmad86:
Says "Error: device not found"

However it now just sticks on the ASUS logo and loops to another ASUS logo and I don't see the Mismatched at the top in red anymore
[Transformer TF300T General] tobdaryl:
This is not unusual for these tablets to change as we flog them.

We once again want to know about recovery, adb, and fastboot access. One or more of these probably changed as well and we need to know which.
[Transformer TF300T General] kmad86:
When I type in fastboot device, it just says "Waiting for device"

ADB shows a bunch of stuff. I'm trying to read through it all right now. It says 1.0.31 for ADB version. I don't know if that's the tablet or the computer?

I'm not sure what to type for recovery? Unless that's the same thing I typed above "adb reboot recovery"
[Transformer TF300T General] tobdaryl:
Fastboot only seems to work from the bootloader, either the usb icon or if that is missing when left on the RCK and shows fastboot starting in the upper left.

Recovery is get into bootloader menu and while on RCK press volume up.

Sorry but these things will test your patience and many give before reaching the end. The end can be positive or negative but I can't see it yet.
[Transformer TF300T General] kmad86:
I edited that after you replied. I got the ADT menu to pop up and I tried just something to see if the tablet was responding so I typed adt remount. It said no device found.

When I hold power and down, It prompts me to push up to go into RCK. That's what I go into when android is on his back with the triangle. If I don't push up, it just reboots the tablet.

I don't see it say anything about fastboot. Maybe I am doing something wrong.

I did just see that the small print when it's prompting for RCK says bootloader <2.10 e> released by "us_epad-9.4.3.17-20120308" a03
[Transformer TF300T General] tobdaryl:
Let me verify on this unit you get android on its back when entering recovery. That numeric is ICS.

Still no usb icon on bootloader menu?
[Transformer TF300T General] kmad86:
Just wipe and android logo.

Android on its back when I go to recovery.
[Transformer TF300T General] tobdaryl:
Android on the back is stock recovery with no file to process.

Now here are the things to consider.

1. If I were buying a new unit and I had a choice I would take the one with ICS. The reason is Nvflash can only be installed while on ICS. Nvflash would have cut through a lot of this mess to get this far (it is a modification that can help to recover your tablet from the worst conditions. If used incorrectly it can also brick a unit or seemingly so.

2. Going from ICS to JB should be through 10.4.2.9 as this version of JB repartitioned the hard drive for JB. If you wanted to use JB 4.2 then from 10.4.2.9 we would need to go to 10.4.2.20 because of the assert in 10.6.1.8(4.2).

Tell me your choices and we'll begin.

Before I forget go to settings/developer options/ turn on developer and check USB debugging.

This option should turn on adb access. I hope we won't need it now but as a safety. No usb icon on the bootloader on ICS means this unit is locked.
[Transformer TF300T General] kmad86:
Settings/developer options? Is this in the SDk toolkit?
[Transformer TF300T General] tobdaryl:
No. When booted into the os go to the app drawer and click settings.

Have I gotten confused and this unit does not boot into the os?
[Transformer TF300T General] kmad86:
This unit loops and loops ASUS logo. Won't boot.

(I Pmd you the update on the one working fine but had 000-0000 touch firmware. I bet that's what you were thinking)
[Transformer TF300T General] tobdaryl:
Now I think I'm on track again.

We have stock recovery so let's use it. We also have ICS. Download 9.4.3.30(ICS), unzip once and rename as we did above, place on your sdcard, reboot into the bootloader and volume up on RCK.

I need to be out for several hours. When I return I'll try to respond to any message you have posted.
[Transformer TF300T General] kmad86:
Ok, so I downloaded 9.4.3.30 and extracted it to the SD card which showed 9.4.3.30-kernel-afee6c5.tar I then put it in the tablet and held power+down and pushed up to get into RCK. From there, it showed android with the status bar below for a few seconds and went to android on his back for a few more seconds with the status bar. The status bar then disappeared and the android was on his back for a few minutes and then it ended up hanging on the ASUS screen (the one with Powered By NVidia on it). It never seemed to take the ICS upload.
[Transformer TF300T General] tobdaryl:
I downloaded also and found the same issue. It should be a zip file. This is source for compiling your own kernel..

I have the proper file but I am restricted to 200meg per file. If you wish I can split the proper one with 7zip and provide two download links.

Or better yet download the 9.4.3.29 file. It is a proper zip and should not be an issue. Unzip once and place the resulting zip on your sdcard and try again.

Sorry for the delay but I had to download both files and verify the situation.
[Transformer TF300T General] kmad86:
where did you download .29? the one in the guide opens as broken to me?
[Transformer TF300T General] tobdaryl:
Try this link it worked for me. In fact using this link I can download .29 or .30 and they work properly.
[Transformer TF300T General] kmad86:
Great, thanks!

Am I downloading the Firmware, or the Kernel? I notice the same version is on both. Or is a Kernel something i'd download if I were modifying the firmware?

EDIT:

Downloaded the firmware and extracted to SDcard as US_epad-user-9.4.3.30.zip haven't ran yet.
[Transformer TF300T General] tobdaryl:
Download the firmware. Yes the kernel is source used to modify the firmware.
[Transformer TF300T General] kmad86:
Downloaded the firmware and extracted to SDcard as US_epad-user-9.4.3.30.zip

Still looping. It didn't want to accept it.

MicroSD Card is also formatted Fat32 as I read somewhere it should be.
[Transformer TF300T General] tobdaryl:
Yes that is the proper format and the card should be <64gig. There are some issues with the larger cards.

We are at the point we need adb to work on this tablet. Then we could push the file to internal sdcard and improve our odds of success. Also if fastboot worked could use that to flash twrp. With twrp in place we could flash the firmware directly.

With the unit locked we have no fastboot. Adb does not work and stock recovery won't process from the external sdcard.

Our only vehicles for rescuing these tablets are recovery, adb and fastboot.

The only trick left that may give us a chance is the reset. It is located about 25mm or 1 inch below the sdcard slot. With the unit looping insert a small paper clip into the hole until you feel resistance. Gently press in and you will feel spring tension, press slightly harder and release.

Tell me the result please.

Actually there is one procedure beyond this but that requires removing the back cover and disconnecting the battery.
[Transformer TF300T General] kmad86:
Reset didn't work, SDcard didn't work with the ICS firmware. What other options do I have that I can try?
[Transformer TF300T General] tobdaryl:
Beyond adb, fastboot, recovery, and reset not much.

Remove back cover and disconnect the battery. I have worked with five who tried and had success. Several others it was no help. Probably about one third success if that high.

If you wish to try I'll provide a little info.

The back cover is attached to the bezel. This means the small division you see at the front is gently pressed outward and toward the rear. A guitar pick, old credit card, or a spudger made for the purpose. I use my nails and a fake credit card from the junk mail with the edges sanded thin. I cut the card into quarters, use my nails to develop a small crack and insert a piece of credit card to hold the crack. Remove the sdcard. I start at the top and work down the left side (the earphone jack on the right side is last since it projects further than anything else). Go slowly and be careful of the earphone jack the power button. A little at a time and work toward the top left corner and the left side up toward the top corner. The back will not completely clear until the bottom left corner and the bottom toward the left corner have a crack. Gently working those three sides back will release the screen.

Inside you will see a large copper plate. Under this plate is a blob of adhesive which will reattach several times. Work slowly and don't bend the plate. Under this plate is a connector with larger black leads. Remove this and let sit a few minutes.

I suggest doing this on an antistatic mat and use a wrist strap.

How do I know how to do this? My dock tried to fry my unit. After the smoke cleared my tablet works but I have no usb connection. I verified through the connector up to the motherboard. My life will slow a little next month and I'll look into a motherboard replacement.

If you don't wish to do this I completely understand. I only mention this because we are trapped on this unit.

The tools used to rescue these units are adb, fastboot, and recovery (stock or twrp). We are out of options.
[Transformer TF300T General] kmad86:
I actually opened all of the tablets with software issues and tried to unplug and replug the battery.

I also suggest to anybody opening it to switch off the service switch which is located by the power button before removal of the battery.

I guess I am dead in the water on this tablet?
[Transformer TF300T General] tobdaryl:
Put it aside for the moment and we'll consider any other options. As I said in the past these tablets have a way of evolving. We might retry adb in a day or two and find it working or even now.
[Transformer TF300T General] kmad86:
I'm going to slowly go back through the thread and make sure there's nothing I missed.
[Transformer TF300T General] tobdaryl:
Good! This unit could prove helpful as a temporary or permanent part interchange.

I have helped three with recovering after a motherboard replacement and have always wondered if swapping back could have provided two working units.
