You could have skipped some in your reading. AFAIK, there is no difference among the touch PCBs in that they can all be flashed with the correct firmware (4820) for the G01, G03 and no label. So if you're gonna replace the 5158 with any of those above, do not spend money on a new touch PCB yet. There's a slim chance the PCB may go bad, but test it out first.

In most cases, the way you go about it is most likely the cause of the trouble, not the faulty hardware. Make sure you follow the directions, especially regarding the battery and/or service switch. I cannot stress this enough: There should be no current going into the 2 Boards at any time prior to, during and after the replacement process. The current should be fed ONLY after the whole thing has been properly re-assembled and ready to be powered on.
[Transformer TF300T Q&A, Help & Troubleshooting] Hottentott:
Ok, I've read almost the whole thread, but was a bit confused since most of the discussions deals with the G01 version. I'll pay close attention to the battery switch, replace the digitizer and flash the 4820 firmware.

I guess I could send my dig back, since the seller on ebay sent me the wrong one, but I don't want to wait another four weeks for the shipment... I miss my old (working) pad! :'(
[Transformer TF300T Q&A, Help & Troubleshooting] Bucwylde:
Thanks for all the help, this thread is fantastic. UPDATE: I installed a different digitizer and I'll be damned it works. Millions of ghost touch = you need a new digitizer(at least in my case.

No label

Hello, noob here. I searched and read 99% of this post but cannot find a definitive answer to my problem. I replaced my broken digitizer (no label) with a new one off eBay. The digitizer is showing "elan 0000-0000" in the about tablet section. I tried flashing the 4820 firmware but every time I do it the device loops in the updating screen. I then have to boot into recovery and wipe everything to get it back to normal. Afterwards I recheck the firmware and it states "4820" is in there but still no touch. I've checked for a burnt coil but my touch pcb seems to be different than the one pic on this thread. The micro SD card slot is working fine as well as the reset button located on the card. Am I out of luck or is there anything else I can do? Thanks in advance for the help!
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
Did the touchscreen work at all when you first installed it? Replacing a no-label with a no-label shouldn't require new firmware.

"every time I do it the device loops in the updating screen..." What does that mean? Can you post a pic of it? Flashing the firmware sometimes takes a few minutes, with the PC screen scrolling quickly as if it's looping to no ends. Was that what appeared in your case?
[Transformer TF300T Q&A, Help & Troubleshooting] Bucwylde:
the burnt coil is on the main board (right near the ribbon cable that comes from the Touch-PCB) not the Touch PCB
[Transformer TF300T Q&A, Help & Troubleshooting] Toledo1979:
I bought it with a broken digi which didn't work. The looping screen I'm referring to states "touch screen is updating". Then it goes to 100% and starts over. After that it tells me I need to restart to update. Then it does it all over again after shutting g down and restarting.

I will check the main board tomorrow for the burnt coil.

All this from the PC screen or the tab? It's the PC screen that displays the process. Can you post a screenshot from the PC while that is going on? The about tablet tab showing firmware 4820 doesn't mean crap. I've switched a digitizer from a working machine to another working machine, and it stammers almost immediately. Vice versa yields same results. I had to reflash every time for it to run again. Does the tab ask you to update as you turn it on?

Thanks for the commands. I can vouch for Vadim's method.
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
Latest on this: I did some more experimentation and have come to these tentative conclusions:

1. Earlier in the thread, I mentioned some technician claiming that about 33% of the new digitizers either played dead or only responded on certain areas of the dig's surface. Turns out he's not wrong, but not completely right either. I concur with this rather bold claim based on parts available on Ebay - which I assume is where most people go to look for digs. I never bought parts from Asus.

2. Assuming nothing wrong with the hardware, new dig stands a great probability of not functioning as they should right off the bat. They would have to mesh with the rest of the system. Some would cause the system to update the firmware automatically. Others would seem to work, but then stop after a while. Still others would work only in certain areas (which corroborates the claim above). And lastly, some would not work at all.

I suspect Asus's stock would fail just as miserably, except there were reports from people who RMA their tabs for major overhaul that when they receive their stuff back, some found an app called "touch tool" left behind, most likely inadvertently by Asus repair personnel, Seems that's what they used to recalibrate the new screens so they'd "sync" with the rest of the system.

In our case, The ultimate cure is firmware re-flashing while the tab runs official roms. 104220 never fails. Custom roms do not always flash right, it's a hit or miss thing. Some would not allow you to flash at all. Once that done, you can then flash any custom rom you want without affecting the dig's functionality ever.

guys, I've just replaced the motherboard on my TF300t because it was bricked. Touch worked great before switching the motherboard, now the tablet boots up to the welcome screen, all great but the touch doesnt seem to work, at all. I had a look and its apparently a G03. Its still the stock digitizer as i have never replaced it.

I suppose flashing the firmware would be the next step here, however, how would I root a device that doesnt respond to touch?

EDIT: I do have a keyboard dock, but the touch pad or keyboard dont seem to work at the welcome screen.

EDIT: see my post below, its all working now.
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
That's impossible. The only time where the touchpad doesn't work is inside TWRP recovery. You check again make sure the tab mounts correctly on the dock - so the release tab clicks all the way to the right. All the way, not half-way.
[Transformer TF300T Q&A, Help & Troubleshooting] XtriFe:
I've just tried again but no luck. The keyboard and touchpad dont do anything but the power button of the tablet on top has the orange light and everything, which means the dock is charging it ?

Here's a screenshot. Also, is this the ICS or JB welcome screen ?

EDIT: guys, guys, guys... it was just a loose pcb ribbon cable. Many thanks to graphdarnell, without his input, i dont think i wouldve taken the time to triple check all connections. It's all working now. Didn't have to flash anything.

Just asking for some prelim info before setting off on another head-spinning ride: has anyone ever done a NAND reflow on these things? If yes, could you please recount the experience. I just want to find out how. Doesn't matter if I destroy or break something in the process. Thanx. If this is not the right place, please move it.
[Transformer TF300T Q&A, Help & Troubleshooting] vadimbrk:
I haven't re flowed this device but did hundreds of others. Keep it simple, if you have a pre-heater, heat the board to about 80C, then heat the chip for a few minutes starting from 100C up to 200C in the end of the process. Why do you need it?
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
I'm playing around with a MB that bricked while updating OTA. The NVFlash-BS-that-never-was predicament, you know. I happen to have a spare Hynix NAND lying around, so... I was thinking of wrapping the board in foil, cut out a hole where the NAND is; then heat it with a heat gun till it gets loose or falls off, whichever way works; then somehow remove the messy melted solder, if any; then hold the new NAND in place and reheat the spot to "solder" it. I have a copper plate but no preheater. Do you think I could or should use it instead? Any other word from the wise before I get my feet wet? Thanks. :)typo
[Transformer TF300T Q&A, Help & Troubleshooting] vadimbrk:
Pulling the chip up should be easy enough. It's very thin so the heat passes to the bga ball fast enough before it damages the chip itself.

You can head the ENTIRE board with the heat gun and when it hot enough heat the chip itself. Foil in not really needed here, in fact, you probably do more damage to surrounding components by moving the foil by mistake. Inspect the chip perimeter for epoxy glue. If you see some, try to scrape it after heating. I'm not sure this kind of thing of recovery will work. As far as I know (I don't really) the same dead bootloader that you're trying to recover is not in the new chip...swapping them won't do anything helpful. One option is find a USB flash drive with the same chip, put the entire system on it and re flow it to the main board. Another method is using UART or JTAG protocol(after finding the pins) to try to load a new firmware to the correct addresses(lots of research).

You need to reflow the chip back which is not the easiest task for the non experienced one without having the right size BGA balls and stencils. Experience is the key here. If I were you, I'll try the jtag route first.

Good luck :)

Installed New Digitizer Works But...

I bought an OEM replacement digitizer. Replaced it no problems turned tablet on and ghost touches right away. I managed to enable sho touch and it shows a line of 3 touches to the bottom right corner at all times. I took the case of and checked the ribbons from the digi to the ts pcb and they are seated properly. Here's the thing if I put my finger on the top ribbon connector the touch screen goes wild, bunches of ghost touches. If I move the ribbon to just the right spot then all ghost touches go away and touch works perfectly. Does this mean that my ts pcb is probably bad?
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
(lots of research): No kidding. I already have the whole firmware installed on the spare NAND. It's just the resolder part that intrigues. But it doesn't look like something that can be done on the cheap without the proper equipment and experience. Might be easier to get someone to Jtag the thing instead. But thanks for the info anyway.

"...Here's the thing if I put my finger on the top ribbon connector the touch screen goes wild, bunches of ghost touches. If I move the ribbon to just the right spot then all ghost touches go away and touch works perfectly..."

You're confusing me. What ribbon are you talking about now? Both ribbons (the touchscreen's to the ts pcb; and that from the ts to the main board). AFAIK, both are locked inside the connectors once you push the lock tabs down, e.g, not movable. How do you "move" either to "just the right spot"? I'm trying to understand the problem to see if I could help, because if the screen would work perfectly when the ribbons are positioned right, the board evidently isn't bad. Can you run that by us one more time?

If you referring to the top ts amber ribbon, that suggests to me that either it's not seated right, or loose; or the connector is damaged somehow. In the latter case, use a loupe to examine the pins inside the connector.
[Transformer TF300T Q&A, Help & Troubleshooting] jakeray:
The ribbon from the digitizer. If I put my finger on one of the connectors the touch goes crazy but only one. If I move the ribbon around I can find a sweet spot that makes the touch work perfect. I am assuming that the ts pcb is bad but I want to make sure there is nothing I can try before I purchase one.

EDIT: Okay I fought with it and fought with to get the 4820 firmware on the tablet and it finally recognized it and updated and worked. It was really strange because I thought that if it needed the other firmware it wouldn't work at all. Guess I was mistaken.

Also I read that there has been a case of 7028 firmware that is for tf700 showing up in these devices. I can confirm that mine was that too. I deleted it with root explorer after copying it to the touch firmware folder and it worked like a charm.

I found that flashing the TS firmware, even if you already have the correct firmware, will reset unmoving ghost touches.

A month after replacing my digitizer, a ghost touch suddenly appeared in one location. I re-flashed the TS firmware and it cleared it instantly (no need to reboot, or hard reset the tablet).

2 months later (Today) the ghost touch reappeared (Ya maybe my new digitizer isn't perfect), I re-flashed again and its gone.

So even if your digitizer works, but you have ghost touches, try reflashing the TS firmware.

TF300T digitizer

Hello Guys!

My name is Gerardo and i´m from Portugal.....Long way to USA :)

I bought last year, in August a TF300T.

5 months ago, i put the tablet under a jacket, putted mine feet by mistake over it and broke the LCD!(Digitzer was working because i had it connected to hdmi input of mine tv and everything was ok).

Asus claimed 250USD for reparing it, and i told them...you can keep it :)!

Searched through ebay for an lcd, bought it, replaced, and i got a working TF300T again.

3 months later the digitizer started behaving erratic, it was difficult to unlock, when in the lock screen...but it still worked...after a few days it started working worst...and worst until it becamed unusable..I tried to set the ribbon the best i could, over and over and by mistake forgot to turn off the tablet!

After seeing that the software version of the TS board wasn´t available...0000-0000 i saw that i must have burned the "famous coil"..after checking with mine multimeter saw that it was burned, and switched for other one!

Beware everyone, to connect and disconnect the ribbom cable of the digitizer with the tablet turned off on the small button on the board!!!!!

(at this point i have 10 ghost touches in the screen, even with the digitizer ribbon disconnected from the TS board!

In mine first try, since i was using an modified rom, was to update to an stock asus firmware..the latest 4.2.1!

In the older firmware there was available at the etc/firmare/ the TOUCH folder, but after updating too the 4.2.1 there isn´t any TOUCH folder....But in the tablet information it says TS version ELAN-3011-4822.

Is it normal that with the "Show Touch" option activated in programmers menu, even with digitizer disconnected, i get "ghost touches" all over the place?

I like a lot mine tablet, and wouldn´t like to buy a new one!

From what i said, do you think should buy a digitizer, or digitize plus TS Board?

Mine digitizer is the 5158N, should i buy the G03!? and what TS board?

Thank you very much for you help, wich is unvaluable :D

After that i will give mine feedback in order to help others in the same situation! :)
