Hello community, I have a problem with a redmi s2 team, the problem is that I do not work the touch part of the screen, as the LCD responds smoothly, as I reviewed information, the problem supposedly only solved with the magic box UMT thing I tried and did not work, so I proceeded to buy the new screen touch, but when I try it, although it recognizes some touches, it does not really solve the problem, it is worth considering as information that once tried to do a formatting with the EDL system of the phone and did not allow me to do such formatting as it asked for authorized authentication EDL xiaomi, which obviously do not have, what other options I have left, besides throwing replace the phone, since the warranty is void, at least in Chile.

Hi,
I just bought used HTC touch pro and have problem with it. It doesn't want to load windows, I switch it on it shows gray screen hangs for 20 seconds and restarts again, please help me I don't know how can I solve the problem, battery is charged!!!!
Please respond me ASAP!
Thanks you
I bought it from Ebay now I need to understand send it back to seller or problem can be solved via flashing. I'm new in this area, it my first PDA phone please help!
You should contact the seller. If they sold the phone as working, then send it back. If they sold the phone as not working properly or for spares/repair then you will be wanting to read the wiki & flashing guides (in the Raphael ROM developement section).
Thanks Beeble for response, the problem is they sold it as "great working condition" , another problem is they ship only in US, I told them to send it to my friend who lives in US, now he contacted me and told that it shows gray screen on startup and restarts after 20 seconds, so I'm trying to understand tell him to end back or you may help me or advice how to solve possible software problem
Thanks again
my friend just told me that now it detects wifi network and asks to which one connect but neither touch screen and buttons is not working. He tried to boot with reset and center button pressed he said now it doesn't switched off even with power button.
Please advice something, it is very important for me.
Tell your friend to send it back if the phone was suppose to be sold in working condition as in all functions of the phone are in working order
I guess I will do so. What do you think, it is a hardware or software problem ?
Its not possible to troubleshoot it from the information given. It *sounds* like a hardware problem, but without seeing the phone, and without (please dont take offence) someone with some technical view who knows what the phone is supposed to do it really isnt possible to be sure. Maybe the seller will get it back, do a hard reset & it'll be fine. BUT unless they want you to do it - DONT do anything. If you (or your friend) starts to play with the software the seller may claim any problems were the result of your "tinkering".
Simply contact the seller telling them the problem, ask if there is anything they would like you to try yourself, if not - or if those actions fail - simply send it back.
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.

i'm going to buy a screen + digitizer and i would have some advice about this, what code should i look ??? there are only two kind of screen or more ? what should i ask to the seller ???
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
My 820 was dropped and cracked, and I had it successfully repaired. It had been having memory issues from day 1, because of all the pictures imported from my Samsung, so I had them do a hard reset after the glass was replaced.
So now I had a physically repaired phone with a clear OS, and I was reloading stuff when a message popped up to update the OS(). I said 'sure' and set the unit down so it could do its thing. I picked it up later, and it was totally bricked. Side-button-based soft and hard resets don't work (buttons respond, but the procedure doesn't work right) and the screen doesn't respond to touch at all.
I simply want to flash it. I tried this procedure from another website, to no avail. I downloaded a lot of files and the Nokia Care App, but I got some permissions denied error, etc.
Does anyone know of a tried-and-true procedure for this?
Much thanks!

The 820 and 920 are essentially the same phone. Just a few higher spec hardware bits on the 920. Use the unbrick guide from WPcentral. Google it. (sorry can't post external links yet as am still in noob status). It does work. I have used it.
Hope it helps.
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
