SM-P900 Wifi Touch Screen has Malfunctioned - Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting

Hello All,
In my attempt to root the device which I was successful in doing somehow things went south when i tried to flash TWRP on my device. I performed the .img to tar.md5 conversion with the CWM Tool on another thread then i flashed the file to my device, afterwards the devices were rebooted and now I am unable to touch the screen with my fingers and only my S-Pen works, which tells me hardware wise the screen is ok but something software wise is causing this issue. Can someone please help me in troubleshooting this issue. I seen another user have this same exact issue but it ended with him sending it to the service center. I have performed a full dat/factory reset.... I have performed a full reflashing of the stock rom i have re-rooted. I am all out of options.
See video i made regarding this issue.

Thanks in advance!

Can anyone help with this

Capacitive touch and spen use 2 totally different chips inside the tablet. The spen uses a Wacom digitizer, while touch interaction is processed using standard methods.
In fact, each one has their own ribbon cable from the screen to different points on the motherboard.
I have no idea how rooting broke your touch ability, but the spen working is not an indication that the touch interaction is not damaged in some way.
I can tell you that on mine (especially when using papyrus) it has a tendency to lose touch until I shut the screen off and turn it back on. Maybe something screwy is going on with the touch driver. Flash back to stock and see if it's still broken

Did the reset work?
I ask because we just got a used tablet off ebay and it is doing the same thing to me. My wife emailed Samsung who said blah-blah-blah so we are stuck with it. I know enough to brick a phone really fast, but I have been running custom Roms a long time and have replaced screens so I may check the cables on my day off.
But it was doing it before I rooted it, recovery, and Hyper-drive Rom.
though the knox had been tripped before I got it, so I don't know what has been done to it before this. So please let me know what you think even if you try it and it does or doesn't work and I will gladly do the same for you.
Thanks--Rick

[Q] HTC Touch Pro screen does not respond to touch

First of all Hello and thank you for having a great forum. I have learned a lot from the posts that I have read. Ok, like I said my touch screen lost its touch. It started acting up last week and got to the point where it would not accept touch input. I tried a hard reset, but I still have the same problem.
I am beginning wonder if any of you sages and guru's may have come across something like this in the past. I tried flashing the device but it is difficult since I can not touch the screen to ok the program load.
So, do I have a hardware or software problem? Also, are there ways to select a soft key other than touch? Thanks for reading and if you got any ideas let me know.

I would say its a hardware failure, especially since you flashed your phone and your screen still wont register any touch. But I would wait for a second opinion before I take it in to be serviced.
Thanks, but I was not able to flash only reset it using the alternative method described on Verizon's website. I am trying to flash the phone with a new ROM, but the phone prompts me to click 'yes' or 'no' on the screen to install new software. Of course, that is a no go. I tried to flash from the security unlocked screen but the flash program will not run. I am almost out of options.
You woudn't be using a case on the phone by any chance, would you? I have noticed some cases extend onto the screen too far, causing it to be touched, and then it wont recognize any other screen touches.
I went through the same thing a year ago, and I found some posts from people with the same problem.
It is caused by gunk getting in groove around screen.
take a business card or similar thickness paper and drag through groove around screen.
If that does`nt work get a piece of duct tape and apply to screen and gently pull off at steep angle.
It will lift screen back up and unstick it.
Oh my God... only now I understand what could happened to my Raphael:-O

i9023 - Replacement screen touch input not working

Hi,
I recently dropped my i9023 and smashed the glass.
Bought a new screen with digitizer from global direct parts (www globaldirectparts com/Samsung-GT-I9023-LCD-and-Digitizer-Assembly-p/smsng6102150.htm)
Having put the new screen in it boots up fine and displays perfectly but the touch screen is not working at all and I can't do anything. If I put my smashed screen back in touch input works fine.
I've flashed back to stock I9023XXKB3 and I9023XXKB1 firmware, but nothing seems to help.
The ribbon to the screen doesn't appear to be damaged and because global direct parts had a minimum purchase of 2 I have 2 new ones and they are both unresponsive.
Anyone have any ideas?
My first idea would be to have the manufacturer fix it.
Sorry you are having trouble getting the touch screen to respond. I too have cracked my screen and would be very interested in your strip down and replacement steps as I am going to be doing the same. If you get time, could you write down your steps. There is a pretty good teardown at
http://www.ifixit.com/Teardown/Nexus-S-Teardown/4365/1
but I am not confident of the last bit of using a heat gun to separate the screen from the frame. Did yours come off easy ?
Yes I could have sent it to an authorized repairer but I would of been without the phone for a a while and it would cost twice as much. Plus I like pulling things apart.
markread544 - I pretty much followed the ifixit guide. however when pulling out the motherboard make sure the front and rear cameras and speaker are loose as well otherwise it wont come out.
I didn't use a heat gun, I just applied pressure until it started to lift, it would of definitely been easier if it had been warmed up but I didn't want to use a heat gun either. You would want to use an adjustable heat one on low if you did, I think a hair dryer would work as well.
I pulled mine a bit further apart then they did, the grey part in the attached pic comes off as well which makes it easier to get the screen out of the front bezel which it is also glued to.
Phone is back together at the moment with the cracked screen but I'll take some photos if I pull it apart again.
same problem here.
i bought an lcd on ebay for i9023 (slcd)
display OK , but no tactil response.
i had MP the OP but still no answer.
if you have any suggestion
thanks
how much for the screen? seems that 9023 is cheaper than 9020
80 euros for the less expensive , about 120-150 for the others
I ended up returning the screens from global direct parts and after about a month they gave me a refund.
After being quoted AU $250to get the screen replaced by an authorized repairer I decided to try again and bought a replacement screen on eBay from a seller called stream_beautiful for $86.
Got it today, installed and it works perfectly. No idea why the original screens from global direct didn't work.
I'm sorry to bump such an old thread, but I was wondering if there was any more information on this issue... I ordered an i9023 screen to repair a friend's phone about 2 months ago and had the same issue as the OP with it; touch input didn't work. I then contacted the seller (forceviewer on aliexpress) and he told me he'd replace it. After sending it back I then had to contact him again and send him pictures of the back of the old screen (with which touch input still works) because according to him there are 2 versions. Now I received the second screen a week ago and lo and behold, it exhibited the same problems. I noticed a number on the back of the screen is different, and the atmel IC (which I assume handles the digitizer input) has a different number on it too, however the seller has now adopted the position that it is definitely the correct display (quote: "If the pictures is right
The item will be right
I just send you the one same with your picturs
There are only two version.
Thanks")
Can anyone shed some light on what causes this? I know the guy's company tests their displays before sending them out, so that's probably not the problem, and receiving 2 faulty units in a row would be a bit weird, so I guess there's actually multiple versions (with a different digitizer controller IC?) which aren't compatible with each other... How do I make sure I'm getting the right one for my friend's phone? And, optionally, how would I go about convincing the seller to take this one back too and send me one that really works?
I'm having exactly the same issue...two replacement screens and touch input non responsive, re-install original and hey presto no problem...what I have noticed is that the part number on what I assume is the digitizer is different...
original -> KJ00423-101228-P00-7F-1
replacement -> KJ00423-101228-P00-5F-1
Yeah, my replacement says 6F-1 at the end, I can't check the original right now because my friend has his phone, but I'm willing to bet it doesn't say the same. Maybe I can make my case with this with the vendor, I'd really hate to have to buy another one of these displays for nothing
Guys,
It's the third SLCD screen that one of my fried is replacing to my I9023 Nexus S, and none of them is working. Yesterday he told me that when he bough the third one, the seller told him to "reprogram" the phone, because the drivers for new SLCD will be installed only then.
To be honest I didn't quite understood him, so, I though that the seller means to flash with a ROM. I did that, I installed CyanogenMod 9, everything went fine, but the touch still not working .
Does anyone knows how the phone could be completely wiped. Meaning everything what is in it to be reinstalled from the beginning....
I don't know what else to do, besides to buy a new phone
Hi All,
Just want to ask if anyone came to the solution yet ...?
Cheers,
no touch
Hello
i have the same problem:
1. The display works
2. But no touch reaction
i had bought a new screen for my I 9023 .
thanks for solutions
Yep, I have the same problem.
Original: KJ00423-101216-P00-1F-1
Replacement: (Not responding to touch): KJ00423-110207-P00-1F1
eBay Seller: mike410512
Bump - anyone sort this issue out?
I know this is an old thread, but since I have a shattered SLCD screen and i'm willing to replace it, i'd like to know what to do in case there's no touch response...
To get touch input again
Hi all,
I have smashed my phone screen twice on my S3 i9300. The first time I had the issue with the touch screen not detecting input but displaying correctly, I had taken it to an authorised repair centre and initially they did not know what was wrong.
There is only one way to "fix" this situation. You must remove the custom recovery and then reflash your phone with the stock samsung rom. Flashing the stock rom with stock recovery should pose no problem as it will be "official" and thus not blocked by stock recovery.
After reflashing, you must do a factory wipe + data reset. This is where you change your screen, making sure not to boot the phone for "the first time". If it does not work, repeat the reflash + factory wipe and try again.
The samsung rom will register the new hardware profile, and touch input will work. Why it works this way is beyond me, but taking these steps when changing the screen on a custom rom will ensure that the touch input works. Perhaps custom roms "borrow" drivers left over from stock rom? I don't know.
You can back up your current rom and restore after messing around with the samsung stock rom and you have gotten your touch screen working properly.
I have tried a whole heap of different "solutions" with this problem and this is the only one that works, and if you are taking it to a repair centre, make them aware that you have a custom rom installed.

[Q] MORE HTC HD2 problems... this one is bad.

I've been having a reoccurring freeze issue with my HD2 no matter what build I am using. On the initial first time startup everything works fine until the display goes to sleep. Once it does, the touch pad freezes. Hard buttons still work although don't do anything since it's stuck on the lock screen, and even if I soft reset or reflash anything, the problem persists.
Not even disabling the lock screen helps. Even if I install lock screen disabling apps (I've tried them all), the touch screen is still non-responsive when I wake the display.
Whether I use stock winmo, custom winmo or android (NexusHD2 gingerbread 2.3.4 as of late, but I've also used the old Desire Android 2.1) makes no difference; neither does reflashing HSPL, radio, ROM, Recovery CWM, reformatting SD card, fixing file permissions or even performing Task29. I've even restored everything all the way back to stock winmo which didn't work, so I performed every step along the road to getting back to Android. No success. I'm at a loss because I've tried every solution I have found online in just about every order imaginable.
There has to be some solution to this issue and I'm hoping that SOMEONE out there will rescue me. It's been a problem since I first got the phone and although even once in a while it will work for no apparent reason, it has been in this status for some time.
PLEASE help. I'm tired of paying a bill for a phone I can't use.
It's most likely a hardware problem. Your digitizer has most likely went out, I'm not a pro but it happened to me before.

Is the digitizer easily fixable or would I need to replace it? Or would it just be overall cheaper to replace?

[Q] Nexus S bricked. Now what?

Hi,
I wanted to update my Nexus S from SlimBean 4.2.1 1.0 to 1.1 this morning.
I didn't do a full wipe which basically ruined my OS so I wanted to back it all up, full wipe and start all over again.
I had big problems with backing up as Titanium Backup either crashed or was stuck at it's initializing SQLite stage.
The phone process and System UI were crashing all the time if that matters.
So I tried to back it up through CWM which first failed while backing up the data partition, but it worked the second time.
I turned the phone off and since then it's not doing anything anymore.
Won't turn on, doesn't show the charging animation when plugging it in.
I tried to recover it several times.
It doesn't show up in Windows' Device Manager and UnBrickableRessurrectorR40 doesn't see it.
Is there anything I can do?
Thanks a lot.
land.apfel
why don't you try to get it to download mode and flash via odin ?
I would do it that way if it was possible. The Nexus won't do anything. Neither fastboot, nor Download nor recovery nor anything else.
The only thing it does is getting hot when being connected to AC.
But I'll try to do the UnbrickableMod and see if it helps.

Did you make the hardware modification? I have to do it with mine to be recognized.

hardware modification is so difficult so as to be impossible for most people. it seems to be the only solution though. i only just bought my nexus s (for $150) second hand .. flashed cwm 10 on it and it bricked a few days later when i swapped a battery. i have disassembled the phone but the modification required needs minute tools and expertise beyond my ability. any suggestions? sending it in to experts in the USA will cost me nearly $100 and I'm afraid the diagnosis might mean I will lose that as well.
Without the hardware modification you can trash your Nexus S right now, as the chance that you recover it for some reason is probably 0.01%.
For doing the hardware modification you really need to know what you're doing. If you don't, look out for someone you know and who would do it for you.
After you did the UnbrickableMod, the chance that you can recover your phone is about 60% (maybe).
If you can't recover the phone, you need to exchange the eMMC chip as well.
I found eMMC chips in China for $19, but you still need to assemble it.
This is where I'm stuck at the moment.
my phone is in same condition please someone solve this and share with us
If you haven't already applied the UnBrickableMod you should try that first.
If you have, I have no idea what to do.

[Q] Two issues: No touch input/Bricked (APX only)

Hi people,
I'm just looking for a bit of friendly advice really. I know there are similar threads about both of my separate issues but I just want a bit of help weighing up my options.
I've been enjoying my used TF300T ('unwanted gift') for about 6 months and had CM10 running on it. I have had (very) intermittent problems with the touch screen of the type I've seen described on the forum, where it will lose touch input completely but will come back on if you reboot it or turn the screen off/on etc. This has probably happened about 10 times in 6 months, and never persisted beyond a reboot.
Last week, whilst I was away from home and perhaps less inclined to do the proper forum-trawling, I had the problem reoccur but it was persistent. No touch input at all. Perfectly functional within the dock though. I figured the first thing I would try was a factory reset. I booted recovery only to realise that I had the lovely TWRP touch recovery installed and couldn't use it. At this point, I decided that this was very probably a hardware issue if touch didn't work in the recovery or the main OS (though there may be things I don't know that still muddy the water here??).
I opened it up to have a look if there were any cables needed securing etc. At this point, I realised I was definitely on my own because the 'Warranty void...' sticker had already been broken ('Unwanted gift', eh?). I played with the cable a bit and could get it to behave differently but only succeeded in getting 'ghost' input allover the place. I figured that at least it was receiving some input now and crossed my fingers that a factory reset would 'recalibrate' it in some way.
In desperation and not wanting to pay too much in roaming data on my phone, I didn't come here and do the reading I should have done. I just installed CWM recovery and used that to do a factory reset (It's not compatible, it hung, I powered it off and now I've killed my bootloader. No recovery, no fastboot, only APX. I've now read this scenario a number of times on the forum :crying. So, with my excuses made and story told, my questions are as follows:
1) Am I correct in saying this brick is unrecoverable at the minute? (I didn't create the blob.bin I need to use wheelie and get nvflash access. This blob.bin is device specific and I can't unpack it from a cm10 or ASUS download? I think I probably only need to reflash the bootloader, so might not need bricksafe.img??)
2) If I were to have ASUS reflash this, I believe it comes in somewhere below $100 and could be worthwhile if the touch problem is a software one.. Do you think the touch problem is hardware or software?
3) If the screen is a hardware problem, can anyone tell me which part I might need to replace?
4) If it needs reflashing and a part replaced (either by me or an ASUS engineer), should I really be looking at selling this for parts and getting a new one economically speaking? Are any of the parts I have actually useful to anyone?!
Many thanks for reading a long and complicated post. If it cheers you up, the garage also told me my car isn't worth repairing this week!
I believe that you have a hard brick.
Asus can fix it but they normally just replace the motherboard and charge in the region of $250 for this service.
Your device will come back locked and you a lot of people have found the unlock tool no longer works. Probably due to serial not matching MB.
Best option is sell individual working parts on eBay whilst they have some value and you might get $200+ back. Or sell the unit as faulty for $100+
Sorry for the bad news.
Thanks for the input, sbdags. In terms of selling the parts individually, is it just really the screen and digitizer that have any value? ..and the dock, I guess.
asus service have tools to unlock force recovery mode and reflash it but it is easy to said us motherboard replacement to get to much money lol
