If we could find out how to compile the kernal to make it work right it wouldn't be an issue. Too bad no one that's a programmer is coming by :(
[Asus  Eee Pad Transformer Prime] t_r_j:
Problem is first new update and it is broke again.

I can't believe that there are this many FuBared digitizers out there.

I wonder if there is some sort of utility Asus has that is used to tweek the tablet with the new digitizer or maybe there is a new digitizer control board that is supposed to be used with these.
[Asus  Eee Pad Transformer Prime] Nightpath:
I think we should go over to the devs here that work on the TF201 and see if one of them can do something for us.
[Asus  Eee Pad Transformer Prime] JaNkIz:
I just had an idea, which could possibly be true....

Can it be that these ebay digitizers are from the TF700??? The connections and the ribbon cable look the same, so maby Asus has pre-ordered the manufacture of these digitizers, and the manufacturers of those digitizers sent them out to ebay resellers as TF201's instead of TF700's, since they look as if they are identical (connector and outer appearance) without knowing exactly which tablet those were ment for

.

I might be wrong though. Didn't manage to find a detailed pic of TF201 digitizer connectors (can someone provide one?), so can't say for sure, but I've found a pic of TF700's connector on iFixit, but can't post a link. Just google "Asus Transformer Infinity TF 700 Teardown"
[Asus  Eee Pad Transformer Prime] Nightpath:
This is mine from my TF201, taken 5 minutes ago.

---------- Post added at 12:48 AM ---------- Previous post was at 12:32 AM ----------

Quite similar to the 700 :
[Asus  Eee Pad Transformer Prime] JaNkIz:
ok, so my theory seems to be wrong. That's a good thing. It's 15 pin connectors for the TF201 vs 20 pin connectors for the TF700. This means that these are the correct digitizers. So all we should need need is either recalibrtion or someone to modify the driver.

Any idea where i could find dissasembled [from an install package] files for the prime? I'm quite keen for looking at the driver myself
[Asus  Eee Pad Transformer Prime] shatz:
For a couple days, programmer from Russia will make driver or something else, which will have invert X+/X- for this digitiser, but he say me, that this driver need to be included in ROM. And i will need to install this rom to my Asus tf201.

Who will can help include this driver to ROM???
[Asus  Eee Pad Transformer Prime] shatz:
Here, it edited. The axis X is inverted.

"You will give this file to somebody from the ROM creator, you will ask a kernel to collect with it.

But I do not think that everything will be smooth:

1) There 2 drivers тача are switched on. While I only corrected one.

2) The axis X can appear is sent to other party and you will receive both inverted axe

Yeah I got teh same reply.

But on another note Asus tech support emailed me back with where I should be alble to get the digitizer. GOing to call around later about it.

Nope, I'm in the military and have been balls out working lately, first to get my car to pass inspection (1985 AMC Eagle), then back to work.

Here's the email they sent me...not really too helpful though, still gotta call and harass them :

Hello, have any news from ROM makers
[Asus  Eee Pad Transformer Prime] Kasper31:
I need help. My screen is cracked. I can not feel the crack but can see it. My screen still allows me to touch the screen and it works so I need to know if it is the Transformer Prime digitizer or LCD that I cracked. I believe it is the digitizer that is cracked but not sure. Who or where is the best site to buy a replacement Transformer Prime digitizer from? Thank you for your help.
[Asus  Eee Pad Transformer Prime] Nightpath:
1 - If the LCD was cracked you'd usually notice it because the screen would be ****ed up.

2 - If you read through the thread you'd see we're still trying to find a working digitizer.
[Asus  Eee Pad Transformer Prime] stage2:
If its the LCD the image / display would be distorted where the crack is.
[Asus  Eee Pad Transformer Prime] dimbazzo:
Maybe we need to start a donation fund for someone who can really fix it?

Me personally and, I believe, other Prime owners (with f***ed up digitizer) wouldn't mind to donate $5-10 for the working solution.
[Asus  Eee Pad Transformer Prime] mechadream:
I'd also do this but a patch is not the perfect solution I think.

If there's a new android version the dev would have to write a new patch and we would have to wait till he finds time to create it.

I would like to see a walkaround with the following steps:

- Get latest android (source) available for prime

- Open the touchscreen driver and fix the part with the x-axis issue

- Compile the sourcecode (necessary?)

- Install on stock prime (including the rooting process maybe)

That would be awesome :victory:
[Asus  Eee Pad Transformer Prime] Nightpath:
We need to find a supplier that can get the proper digitizer. I'll be calling around tomorrow to see if I can get the right one from Asus support.

Going to take a look into how to edit the driver for the newest OS.

On a side note, has anyone installed the newest Android that just came out on their TF201 to see if it fixes their X axis issue?

Edit : if anyone finds me a tutorial about driver editing (I'll be busy for a bit) post it here, I'll see if I can learn enough to edit
[Asus  Eee Pad Transformer Prime] t_r_j:
Anyone found a solution yet?

Or a supplier of the correct digitizer.
[Asus  Eee Pad Transformer Prime] Nightpath:
I'm talking with one of their support, he was interested to know in how my TF201 fell apart.

Next email I'll ask him where I can buy just the digitizer. I don't care if they decide to replace it for me (would be nice) but I just want my TF201 working again so I can enjoy it.
[Asus  Eee Pad Transformer Prime] mechadream:
Updated to the latest (Jelly Bean) and the issue stays the same :/

A while ago a supplier told me there are two versions of the digitizer. Maybe I can get him to send me pictures of the two versions with detail pictures of the flex cable (think the problem is the cable).
[Asus  Eee Pad Transformer Prime] Nightpath:
From what I've read around from a few people the inverted x-axis have a noticeably different path in the cable.

I wonder if the cables can be swapped.
[Asus  Eee Pad Transformer Prime] Nightpath:
If anyone still reading this has bought the replacement digitizer, can you take a picture of the back of it for me, specifically where the ribbon cable hooks up to it? I have a feeling that the cables can be swapped out.
[Asus  Eee Pad Transformer Prime] mechadream:
I don't think it's possible to swap the cables.

I attached 3 pictures of the original digitzer cable and 2 pictures of the replacement (x-inverted) digitzer.
[Asus  Eee Pad Transformer Prime] Nightpath:
Hmmmm...it looks like the ribbon cable is stuck on with some form of glue. You can tell where they attach to on each digitizer, that's fair enough to see, but I wonder if it can be removed with a bit of heat and carefully lifted off.

Where the ribbon cable attaches, are they the same width and appear to be the same count for "pins" ?

If you could snag some really good close ups I'd appreciate it.
[Asus  Eee Pad Transformer Prime] rmspower:
Hi I have droped my asus transformer tf201

Hi

I have dropped my Asus transformer TF201 and came across this site lucky I did, here is a photo of my cable if it helps :)

anyone had any luck yet? I did come across this http://www.ebay.com.au/itm/26103620...X:IT&_trksid=p3984.m1423.l2649#ht_3625wt_1163 on ebay He is claiming he knows about the 2 different replacement digitizes but when I emailed him I don't think he understands much English so its hard communicating with him, anyone here know any Chinese?
[Asus  Eee Pad Transformer Prime] Nightpath:
Cable pics are common, close ups of where it attaches to the digitizer are whats needed.
[Asus  Eee Pad Transformer Prime] rmspower:
Ah ok I will rip it apart again ant see if I can get a few shoots :)
[Asus  Eee Pad Transformer Prime] Nightpath:
Every time I look at my damned tablet I'm pissed. I feel like going to Futureshop, buying one with protection, walking out, swapping the screen and returning it. Whoops! Might be out a few bucks but I'd get my money back and a working tablet.

Sigh...
[Asus  Eee Pad Transformer Prime] Jgrimoldy:
I recently purchased this replacement glass: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130767719924

Sadly, when I connected it, the x-axis was reversed. :(

Fortunately, I had asked the seller in advance about what to do if this happened. I was assured that they'd take it back. Nice. Still though, I have a cracked digitizer glass. I found the sell that you mentioned and sent him (her?) a message last night, asking how to be certain that the right glass is ordered. Waiting for a reply. Based on your posting, it sounds like communication may be difficult.
[Asus  Eee Pad Transformer Prime] Nightpath:
I've contacted literally every eBay seller today, waiting for responses to see what they say.

If we only had someone smart enough and willing to mess with the damned driver I know we could get it fixed.

Or if someone had a bit of electronics background (like me) and has both digitizers and willing to experiment a bit, I wonder if the ribbon cable can be swapped out. On my original it just looks to be glued down. Wondering if a bit of heat (hairdryer) and a credit card to peel it off would work.
[Asus  Eee Pad Transformer Prime] stage2:
Hrmm... could be interesting, although i have already thrown my old digitizer out :(. Why dont you have a go at removing the cable from your old digitizer since it is already damaged?
[Asus  Eee Pad Transformer Prime] Nightpath:
The screen still works, and it's all in 1 piece still...I'd like to keep it that way for now, but if someone here has removed theirs already it would be a great opportunity to test my theory.
[Asus  Eee Pad Transformer Prime] Jgrimoldy:
Nightpath,

Hmmm... I hadn't quite considered the approach of swapping out the ribbon cable from the digitizers. I have an electronics background, but any work that involves disassembling the TP seems that it'd be better aided by having a watch-making background. :P

I felt it to be a victory in and of itself that I successfully re-assembled my TP after testing the screen that didn't end up working. Those clips that hold in the ribbon cables can be VERY easy to break if you don't know how they work.

Anyway, before disassembling my TP again (and tempting fate), I'll scrutinize the replacement that I currently have and see how the ribbon cable mounts to that. This'll give me a better idea of feasibility. When I disassembled mine, I save that the cable was taped down with yellowish scotch-type tape. I didn't spend too much time looking at that since my objective was to test the replacement screen *first*

I'll post a follow up after I get home tonight with my findings... I don't hold out too much hope though. Why it's reversed in the first place is a puzzle. I know (all too well) that hardware gets reved all the time. I'm surprised that a revised digitizer still uses an identical connector. I'm certain that Asus had their reasons for doing this revision. I can't for the life of me figure out why on earth the revision would simply be s pinout change on the ribbon cable. That just doesn't make any sense. Still, I'll see what can be done without jeopardizing my current cracked (yet working) setup.

Has it been confirmed with Asus support that there's no way to change the x-axis thru firmware?

EDIT: I just called Asus Tech Support to get more information on this issue. For such a great product, their support is patently useless. The tech was unable to confirm/deny if there were different revs of the digitizer and wanted me to just open an RMA for digitizer replacement. He could not quote me a price. I will need to wait 24-48 hours to hear back from Asus to even get information on price/turnaround. UGH. As a side note: When I asked about getting replacement rubber feet that came off oy my keyboard dock (which I would have been happy to pay for), I was instructed to create an RMA. I knew, heading into this, that I was going to get crappy support. I was not disappointed.

EDIT: Voicemail left by ASUS RMA support. The minimum cost of having ASUS fix this for me will be $225. In the message, I was told that it could be significantly more. I will need to call back to get additional details. I will need to box/ship to god knows where at this point. This is MOST DEFINITELY one area where the iPad is HEAD AND SHOULDERS above Asus: SUPPORT. At least if you're willing to fork-over the cash, you can go to an Apple Store and get the work done. Hey Asus: Whiskey-Tango-Foxtrot?!?!? Great product.... as long as you don't break it... :(

-JG
[Asus  Eee Pad Transformer Prime] mechadream:
Three pics of the original/replacement digitizer. The digitizer-cable is attached to the digitizer on the FRONTside!

It's kind of glued, if you rip the cable off once it won't stuck on there again, hard to explain. I don't think swaping the cables is a possibility.
[Asus  Eee Pad Transformer Prime] Jgrimoldy:
Mechadream,

Thanks for this. It looks like I won't need to look at this when I get home. I really don't suspect that it's only the cable that changed anyway. I'm sure there's much more to it. If it was going to be easy to switch out the cable, I'm all for trying that. Otherwise... well...

I seem to recall reading somewhere (probably earlier in the thread): If you have a small crack, live with it. It's looking more and more likely that I'll be adopting this mindset... :(

-JG
[Asus  Eee Pad Transformer Prime] stage2:
Damn this really sucks! I don't think I will ever buy another Asus product after this experience, funny enough this was my first Asus product, seems like it's going to be the last one too!

So really our best option so far is to buy the inverted digitizer and hope someone can edit the kernel? *sigh*
[Asus  Eee Pad Transformer Prime] Jgrimoldy:
I'm assuming that for some folks, the digitizer won't be inverted. There's gotta be some that the after-market replacements work for. It's so frustrating because I'm otherwise quite happy with my tab.

I was told by an eBay seller that I should be able to invert the x-axis if I root my Prime. Though I'd rather not root my tab, I will if it will let me use an inverted screen. The seller didn't give me any instructions beyond that. Seeing as how nobody else has discussed that approach online to resolve this problem, I'm not going to do it at this point.
[Asus  Eee Pad Transformer Prime] Jgrimoldy:
Mechadream: I can absolutely confirm that the ribbon cable appears to be permanently connected to the replacement HannsTouch digitizer that I recently purchased. Though you *could* separate the cable from the digitizer with sufficient effort, I won't re-attach. No way, no how.

It appears that it was very precisely sweat-soldered to the digitizer, and those contacts are darned small.
[Asus  Eee Pad Transformer Prime] Shaky156:
People still have this problem? I see op has replaced it, just got a pm that this issue is still on going?

[Asus  Eee Pad Transformer Prime] mechadream:
Problem is still there, no solution to fix it yet.

Think there are a lot of ppl with this problem but why should everybody open a thread if theres this thread and still no solution :(

There are a few threads about this problem on xda and over @ transformerforums.com

I think everybody who will ever get a broken digitizer has to face this problem because theres no source for a working digitizer.

Hope we'll find a dev that takes a look at this :rolleyes:
[Asus  Eee Pad Transformer Prime] Nightpath:
Hmmm...what are the numbers that are on your ribbons that came with the TP, and the ones that came with the replacement digitizers?

I've gotten a few photos from the various ebay retailers, I'd like to compare. My thoughts is that there are 2 stock digitizers and several replacements.
[Asus  Eee Pad Transformer Prime] Shaky156:
Locate to me all the xda threads??

Someone did pm me about this problem

I'll have a look into it
[Asus  Eee Pad Transformer Prime] Jgrimoldy:
Here's what I've got:

The HannsTouch cable is on the replacement digitizer with the inverted X-Axis. The other is the original cracked digitizer. It looks like I need v0.3 not v1.0 (along with lots of other folks).
[Asus  Eee Pad Transformer Prime] Shaky156:
can 2 people, 1 person with a normal working TFP & 1 person with a inverted TFP pm me?

also you'll need root access and custom ROM/Kernel on there I might create a custom kernel for test

[Asus  Eee Pad Transformer Prime] stage2:
:( I only just bought the replacement screen which hasn't been delivered yet thinking we would be able to solve the issue. I can help once I receive the screen.
[Asus  Eee Pad Transformer Prime] Jgrimoldy:
Where did you get your replacement screen from? Have you already disassembled your cracked Prime? Have you taken a look at the digitizer ribbon cable that you currently have? From what I can tell, there's two versions. A v0.3 and a v1.0.

Myself, my cracked Prime has a v0.3 labeled ribbon cable on the digitizer. The first replacement I got was a v1.0. When I installed it, the x-axis was reversed. I can just about guarantee that you'll have the same problem if your versions of factory and replacement are the same mismatch as mine.

I have found a source for the v0.3 digitizers for about $90. * BONUS* They are here in the US on the east coast. I haven't received mine yet. I should on Tuesday (10/16) or Wednesday. I will post about my (hopeful) success. Even if I get the right digitizer, it looks like there's still a bit of work to actually get it permanently mounted (without breaking it or anything else).

Be very careful when you receive your replacement screen. Open it just enough to look at the silkscreen on the ribbon cable. You'll want this to be pristine to pursue a return/refund if need be.

Open your Prime and take a look at that cable. There's many photos on this thread.

FWIW, the two connectors that hold the ribbon cable in can be hard to figure out if you're not familiar. The back of the connector (the whit-ish part) flips up to release the pressure holding the ribbon cables in. It hinges where it connects to the black portion of the connector. You should easily be able to flip this up with your fingernail.

You can remove the cables whether or not you flip up the tabs. You'll have ONE HECK of a time getting the new ones in without flipping up the tabs.

I just make such a point of this because these types of connectors (particularly this small and delicate) can be catastrophically damaged if you don't know how they work.

Cheers!
[Asus  Eee Pad Transformer Prime] stage2:
Yeah I have already removed my digitizer and it was a V0.3 as I stated earlier and yes I bought the V1.0 so I know it is going to be inverted. The reason for the post I was relying on Shaky156 or someone else to modify the kernel for us but hopefully you have find the right one.
