hI..The first time when i changed the digitizer with g01 i flash the firmware 4820ekt.All good but the digitizer had dead area.Then I thought the firmware it is fault for dead area and then flash the 7038ekt but nothing happens.Digitizer not working-no touches.I read all post and no solution to go back 4820ekt.Finally i changed pcb i flash the 4820ekt and digitizer working with no dead area.

I believe was my mistake.What i mean?...Before change and flash new digitizer,i had to pull out cracked digitizer.When i pull out ribbon cables i cracked the pins from pcb..Look the photos with red circle from old pcb.I guess is the reason the new digitizer working with dead area..Can i fix that?

Misunderstood on my side, I thought you had found another controller PCB. Yes the white tab just flips up and hinges on the side towards the ribbon cable.

You will have to replace the complete connector on the board or get another board unfortunately. Maybe someone on this forum has a spare from a dead TF300.

Need to keep flashing the touch firmware

Hi to all,

I too have an Asus TF300T and I have "successfully" updated the touch firmware following the replacement of the digitizer. The problem I have is that while the tablet may work fine for some time (even days), at some point I get random touches and then the only way to recover is to reflash the same firmware (02-3011-4820.ekt). Then it is OK for some time again. Does anybody have a clue why this is happening?
[Transformer TF300T Q&A, Help & Troubleshooting] Matchless 2015:
Try re-seating your digitizer ribbon cables. My wife had random touches and hers would not scroll randomly. I activated 'show touch' in development option and carefully touched touched over the complete screen and noticed that a horizontal band and a vertical band was actually not responding. Carefully reseated the ribbons and its perfect again.

Cheapest and easiest check!

Need to keep flashing the touch firmware

That could be a possibility, I guess. However, in my case, when the touch works it works without any issues. The problem with opening the tablet again is that I would need to get hold of suitable double tape. I don't think the existing tape will survive another opening!!! Out of my head, I don't know what double tape I need exactly. So, it is not the easiest solution :silly:. That would be a modification/deletion of a system file or a different firmware :p

Actually, what I cannot explain is why the problem goes away by reflashing the same firmware...

In any case, thanks for the suggestion. I will give it a try as soon as I can and report back to all of you. In the meantime, if somebody else has experienced relapses of the touch functionality, I would like to hear how/if you solved the problem.

Till next post, cheers and BTW thank you all for your posts as I would not have a working tablet without everybody's help :good:

hey everyone, sorry I don't have time to read all 102 pages. My girlfriend's touchscreen is cracked and I want to make sure I get the right one. How do I tell which version she has?
[Transformer TF300T Q&A, Help & Troubleshooting] Matchless 2015:
The number is on the ribbon cable, but you could use any of the replacement touchscreens as long as you have the proper firmware loaded/flashed to the touchscreen driver board. You may have to sit down and read, otherwise the chances are good you are going to be very unhappy!
[Transformer TF300T Q&A, Help & Troubleshooting] john.greece:
Yes you need to see the version of your digitizer.There are 4 version.G01,G03,No label,5158N.

You may read some of all pages for knowing about falshing new digitizer and differences of digitizer versions.If you install new digiter and need flash wrong firmware you damage your touch board.I say that because i damaged my own board.

Now you can tell us which you firmware you have on your tableg.I think you can see on settings-about phone-touch version,otherwise you should open the back of your tablet to see your version

Hey I found 69.10I21.G01 on a ribbon cable i the corner, does that sound right? So I need to buy digitizer version G01 and swap them out? do I need to change the touchfirm ware?
[Transformer TF300T Q&A, Help & Troubleshooting] Matchless 2015:
You should buy a G01 replacement touchscreen and your touchscreen firmware should not need any updating.

Usually depending in the version touchscreen firmware installed you may or may not have to flash the firmware for other version touchscreens. Some later versions of firmware caters for most or all of the touchscreens versions.

Fixed Non-Responsive TF300T Touchscreen - try this>>>

Had a suddenly non-responsive touchscreen (not broken, white label version) and tried re-seating the cable ends (twice) with no success. THEN, I tried this, and it WORKED :

- disconnect both the small-end connectors.

- Power up the tablet

with the digitizer cable disconnected

and give it a minute.

- Power down.

- Re-attach the cable ends

- Cross your fingers and power up.

- VOILA! It works!!!!!!!

I'm guessing what happened is that when the system did not find the screen, it either re-loaded a default file, or perhaps it just reset something in the hardware. (Or, perhaps, I just got lucky.)

At any rate, try this first, before you go buying a new screen if your old one appears OK but just stops responding. Don't forget to cross your fingers...

How do you identify which digitizer to use? I thought my power button had crapped out and bought a replacement, but in my stuffing around it looks like I've stuffed the digitizer as touch screen isn't working.
[Transformer TF300T Q&A, Help & Troubleshooting] Goddly:
Hey guys, I broke my screen (obviously) bought a replacement, installed it. Didn't work. So I put it in a box and forgot about it. I pulled it back out, checked xda just to see. Found I had three older model digitizer. And replaced it with the g01 version.

Now. I have a (very used) dock I was using to control the tablet with. I grabbed the proper touch screen firmware for the G01, and figured I could push and perm into the firmware folder. So I erased the existing , pushed the new, set permissions. Then rebooted.

It said. "updating touchscreen firmware" but was stuck at 0% I thought I had it! So close! It won't update. And I don't know what to try now. So I cold booted to get back. But now that I've done something. With the firmware, I get insane ghost touches making trying to run the tablet impossible. But this is an improvement as I had absolutely nothing before. So I'm sure it will work. But not sure what to do to fix it. I have twrp 2.6 installed. (I haven't updated anything since I put it in the box years ago.

Any suggestions? I've read most of the thread. Went from looking at the tiny coil, to thinking I had this solved.

I am on cromi x 4.2.1 ROM
[Transformer TF300T Q&A, Help & Troubleshooting] Goddly:
Well. Update. I pulled the cables for the digitizer. Using the dock, I used terminal emulator to flash the firmware. First had a write error. Mounted the system partition again. Re ran. Everything went successfully. Rebooted. Crazy touchscreen good touches. Dragging the screen. It would even unlock the lock screen by itself. So. There's was particles in between the LCD and the digitizer (might be the problem? Cleaned them off both the digitizer and LCD. Well, apparently I pressed to hard on the LCD. As it broke... I turned it back on. And had the lines and the dead side of the screen past the area.

Still had the ghost touches happening after that anyway. Want any where near as bad. But they were still there. Smh. Sigh. Well that was fun! This thread was extremely informative!

Hello

In the past (two or three years ago) I have broken my touch screen tablet, so I had change it with new one but I got sometimes some ghost touch screen.

And at not very long time (I don't know why I’ve done that) I’ve decide to clean the little board whose control touch screen with screen cleaner and it stopped to work, then I changed this last one with a new one (60-OK0GTC1001-C01) but unfortunately it has wrong reference, according to this;

and there was grilled fuse on the main board who's I fixed.

I have searched and found that I need to flash touch screen board, but the tablet must have rom stock.

I also tried this without luke

The problem is; the tablet has custom ROM (with TWRP recovery) and it's no more detected when I plug it on the PC. to get it back to ROM Stock.

I have tested the conductivity from USB to the main board and there is no problem. And also, just in case I have soldered a micro-usb to the main board and the result was the same.

Last thing, the charger of the tablet is broken, and I'm using a charger with 17 V end 1.6A (I have tested one with 12V 2A but it's not works every time) perhaps the problem is coming from there, if the tablet is not detected.

1) Is there any way to flash TS-PCB under custom ROM ?

2) If no, how can I get back detected the tablet by PC ?

3) If no, is it possible to flash ROM Stock under TWRP recovery ?

I hope that someone can help me.

Thanks

Under custom ROM there is no touch_fw_update command and therefore you cannot update touchscreen firmware.

Take any other ASUS TF300T, connect touchscreen PCB and flash it there.

Downgrade from 7038?

Well, I'm one those unlucky folks who managed to get the 04-3021-7038.ekt firmware loaded on a TS-PCB for a 5158N causing the Tablet to report Touch Panel Version ELAN-3021-7038. Apparently this is a TF700T version and once loaded keeps any other Touch FW from being loaded. Has anyone found any method around that to get an older version of the Touch FW loaded?

I had no touch function after replacing a 5158n digitizer. At the time the Touch version reported as ELAN-3011-4822. I successfully loaded 02-3011-4820.ekt and it started reporting as ELAN-3011-4820 and touch immediately started working but I had significant "ghost touches" or random instances of touch triggered without touching it. That's when I tried to load the 7038 version since I had found it originally on the tablet but once it loaded I lost all touch functions and get the errors mentioned and re-added below. For whatever it's worth I'm running Android 4.1.1. and Build JRO03C.US.epad-10.4.2.18-20121122.

I wonder if I could get a hold of a TF700T if I could install this TS-PCB and downgrade the firmware.

Maybe someone has an extra TS-PCB they don't need? If the answer is in this massive thread I couldn't find it but I see some awesome resourcefulness here.

Anyone, please?
[Transformer TF300T Q&A, Help & Troubleshooting] rhysd:
Hi Skiffie, it sound like you didn't replace anything but just opened the unit to attempt to fix the power switch and now Touch doesn't work? If that's the case you've probably blown a small coil that can easily be jumpered. Search this thread for "coil" and you'll find some info.

If you did replace the digitizer, and the coil is fine, then use the instructions to flash the Touch FW with the version 02-3011-4820.ekt. This seems to work with all TF300T digitizers.

---------- Post added at 09:30 PM ---------- Previous post was at 09:15 PM ----------

Betanman, the Touch_Fw_update tool is available directly in this thread for download. I don't know if you can run it from a custom ROM but I would think so. Be careful what FW you use. Some reports identify 02-3011-4820.ekt as universal.
[Transformer TF300T Q&A, Help & Troubleshooting] betanman:
unfortunately I don't have other ASUS TF300T

Like I've wrote before, the command doesn't work under custom rom.

any way I've ordered another screen digitizer with revision 5158N FPC-1 and I hope it will work with my new TS-PCB
[Transformer TF300T Q&A, Help & Troubleshooting] betanman:
Last news, it doesn't work :crying:

I think the problem is coming from the mainboard , because when I test voltage on fuse I had changed I get 1.8V and with ribbon removed who's supply TS-PCB I get 0V

So anyone can tell me the voltage on that born and if possible it coming from where ? I'll appreciate it.

I have attached a file of repairing guide that I've found on Russian site but I can't completely figure out how to use it.

Hey all- I've been lurking in this thread a bit, and much as I'd like, I don't have time to read all thousand+ posts. Sorry to just jump in like this, but i'm sure ya'll understand in this case. :)

I have a touchscreen scenario of my own, and after trying some of the methods within the thread, my tablet is acting real strange... Which at least is progress, of a sort.

Tablet cobbled together from spare parts... I had no clue about the whole 5158N flex cable dealio- when touchscreen didn't respond at first assembly, I just swapped the pcb. Or actually, I think it was the sd slot that wasn't functioning the first go round, IIRC... Anyhow, I knew the tablet had a dead zone on the left hand side. Sometimes you can get a back arrow tap, for instance, but usually not. I've been using the accessibility zoom feature and flipping the tab if needed. Removed/cleaned/reseated stuff, and no real change. Tried dev opt>show taps, and like magic, the touchscreen worked perfectly! After shutting down and restarting, it didn't hold. Tried same process, and got a little more function than usual. Weird.

Booted w/o touch flex cable attached, shutdown and reattached, booted up... First few times, you'd get to the unlock screen and it'd immediately warm boot to the splash screen. Did this 4 or 5 times. Now it'll load without rebooting, but i have a lot of 'long press' ghost taps.

At this point I decided to fool with this flex cable while the tab was on. Uh... Am I supposed to be able to manipulate the touchscreen via the flex cable? This is really weird.

If you've seen any of my threads on batteries lately, yes this is the same tablet that "charges" batteries but won't increase the mV (according to some free battery calibration app), and can't maintain power unless plugged in or holding power button. .

Four years ago, I got a TF300T. The former owner wanted to throw it away, because after the repair of the digitizer, the digitizer partially doesn't respond, as it should. (ghost touches)

Now, the digitizer is cracked. I have opened the TF300T. The installed digitizer type is G03.

The firmware is ELAN-3011-4822, the chips are eKTH1036AWS and eKTF3624BWS. After reading of this thread, I think this numbers don't match.

It seems, that the repairshop has built-in the wrong digitizer? 4822 means, I need the expensive type 5158N?

I did not find the recommended firmware for G03, is it 4817?

Does it make sense to order a G01 and install firmware 4820? (11,98 € taxfree)

(G03 = 22,98 €, 5158N = 36,98 € + import tax)
[Transformer TF300T Q&A, Help & Troubleshooting] monogwai:
I don't know what kind of access you have to used parts, but...i'd try to find a 300 with a g03 digitizer, and take the touchscreen/microsd pcb board from that tablet to use with the tab in question. However, now that the touch is broken i guess its a moot point. Buy *any* replacement digitizer and simply pair with the appropriate control board, and you should be g2g. I've cobbled together many a 'Frankenstein's TF300 monster' from spare parts, and it's worked for me so far. Digitizer swapping...catch the fever. :eek:

Found a solution!!!

Tested on 5158N mainboard + 5158N TS PCB + G01 touch but probably work on any combination.

Do it on your own risk, you can kill your TS PCB !!!

1. Get familiar with the donation mechanism :)

2. Root your device

2. Get the firmware https://github.com/dasunsrule32/proprietary_vendor_asus/blob/3c5a548b8eb556e5f42cc91d4d630ca3ecfc6200/tf700t/proprietary/etc/firmware/touch/02-3011-4820.ekt?raw=true

3. Get it into the device:

adb push 02-3011-4820.ekt /data/local/tmp

4. Get yourself into the device:

adb shell

su

5. Delete touch firmware. After firmware update and reboot the device may update the firmware back to whatever is in the firmware folder which is the wrong firmware. It will kill the ic ability to update the firmware again. <---HELP NEEDED

In the shell:

rm /system/etc/firmware/touch *.etk

6. Update firmware:

touch_fw_update -u /data/local/tmp/02-3011-4820.ekt

7. Get more familiar with the donation mechanism :)
