[Q] Touch inop after repair - Sprint HTC EVO 4G LTE

Ok, so here's the deal:
My nephew has an HTC Evo 4g LTE and just out of the blue gave him a 'system error', powered down, and would not restart. After talking directly with HTC and a local repair shop, we determined that it had a bad motherboard.
I then purchased a used phone off of Ebay as a donor for the motherboard (the original phone is in pristine condition, and I wanted to keep it that way). The donor phone has a shattered glass, but is fully functional. Please keep in mind that both of these are stock, never rooted or unlocked, and were never opened up before (black sticker was still in place over motherboard cover screw on both units).
Today I did the transplant. I have what I believe to be above average technical and mechanical skills. The process of disassembling and reassembling the phones was done very cautiously and meticulously.
Here's where the problem comes in. Upon rebooting the original phone with the transplant motherboard, the touch no longer works. I removed and replaced the motherboard 3 more times, each time making sure everything was properly plugged in and locked down, but I still have the same results. I did do a factory reset and a recovery through the bootloader menu.
I figured that someone here must know what is going on. The original phone worked perfectly before the 'system error', and again, the donor phone worked perfectly minus the shattered screen. Does anyone have some insight on what might be the problem? I would hate to have to purchase a new phone unless absolutely necessary. Like I said earlier, this is my nephew's phone, and he does not currently have a job, so any fix would require me to pay for it...

I'm not going to try to go into much detail on a subject that I don't know about, but you might want to look into troubleshooting and researching to see if your digitizer has been ruined in your transplant. From what I understand, it is a pretty common occurrence in some users' DIY endeavors.

Super Urgent..

First of all I admit that i have done stupid thing.
Before telling this I did HSPL to flash radio rom.
Yesterday I dropped my phone.
And from that time on vibration hadn't worked and booting phone by its own hardware buttons also,not working.
But I found booting only works by following method:
plug in charger while battery is out and then press as soon as battery is inserted again.
Now, what I committed to fix my vibrator was that i tried to disassemble and I got stuck at separating the housing with the screen one.
But I just adadoned to fix it and assembled it again.
After I booted my phone by that strange method above, the touch screen did not work.
So I pressed reset button at the back.
Now it is stuck at the first HTC logo screen. (think it is bricked?)
However It doens't show any information about R,G,D just the logo.
Many time till now the result is the same.
Now my question is...
My warranty is not over yet so I think I can get the new one.
However what interrupts my mind is that "what if they find out it is HSPL?"
But my opposing the question above is that can they see if I did HSPL or not since bootloader doesn't work, and proper powering on of the device doens't work either.
So what is you guys opinion will I be ok to get new one without being accused..?
My other concerns are that what if the boot loader suddenly works... and they find out!!?
And also what if they find out that i disassembled once.. cause the screws look touched..
lol while editting.. the phone got RGDs back although it seems it is rare,now it means there is chance for them to notice it..
You will find that your warranty does not cover accidental damage, so the shop you purchased it from probably will not replace it.
Unless you took out insurance at time of purchase that covers accidental damage.
Your best option, is to claim under your household contents insurance, but once again, check that mobile phones are covered, some policies do not, as it is an item you take out of house.
Thanks for your reply, I am really blured ,because i'm now on relatives house abroad..
Initially when i get back i will check..
unless you have insurance I cant see you being covered I hope you are though, any form of insurance with the HD2 is a must imo
HSPL + visible damage from the fall + disassembly evidence (there's a sticker on a screw that will be broken if you unscrew it, to show it's been opened) = definitely no warranty.
Even if there was any chance you could claim warranty, HSPL modification alone would void it. And unfortunately there is no way to revert unless you install a stock ROM from SD Card. I know it very well cause I just did it yesterday. Had to send mine to claim warranty as the touch screen failed...

FFC modded Vibrant warranty exchange?

I currently have a FFC modded vibrant and its acting up. I know this is an issue with some phones where it thinks the usb cable is plugged in when its not.
This just started happening yesterday after getting the phone on the day it was released. I have Odined back to stock, changed usb settings and multiple reboots the problem still exists in addition it needs to be plugged in to boot up. I got on the phone with TM and they thought it would be a good idea to replace it. So the rep proceeded to give me all the terms and asked me to give her the IME number and so forth. I then turned the phone back on and now its working fine. The replacement phone is on its way already. When she was reading me the terms she specified if the phone is damaged in anyway I will be charged $400+ for it and by doing this I have waived them replacing it for the insurance deductible.
Has anybody successfully covered that hole up so its not noticeable? And what steps were taken?
Should i just take a chance with my current phone and keep it although the problem might come back?
EDIT: It just started happening again after plugging it in with the official cable which feels kinda loose, I used a BlackBerry one which feels nice and tight right before and it was fine.
If it acts fine send them the new one back call them and tell them you figured it out you might not be able to replace it if it acts up again though cause you will be passing this replacement up
Still flashing , thanks to odin & tw
You opened the phone, which voided the warranty. I can't see any way of you easily covering the hole in a way that they won't notice it. You're likely going to be coughing up the $400.

I dropped my phone :(

Now my lower touch screen acts on It's on. I have calibrated the screen but it still acts on it's own. Will removing the screen and putting it back help? I'm thinking maybe it will release pressure from the lower screen that it's causing it to act weird. I shake the phone during a txt and it randomly starts selecting letters. Any ideas?
Sent from my PG86100 using XDA App
I had a similar issue, but for me the problems randomly started on its own, not after dropping it. I brought it into sprint, they changed the screen and said that didn't fix it. They replaced my phone. Make sure you unroot before you go in, if you decide to.
According to some sprint techs, and several other people that have anecdotal stories about repairs by sprint, fixing a physical problem with the phone doesn't require un root. Rooting voids the HTC warranty, but won't prevent them from fixing something like that.
Anyways, your problem most likely lies in the touch screen digitizer, or the ribbon cable connection from the digitizer to motherboard. If you are not capable of fixing it yourself from a tear down guide you can look at from here on xda or across the internet, then you will either have to have sprint do the repair or get a replacement. Remember though, replacements are almost always refurbished, and will likely come with hboot x.5 or higher, and you won't be able to have true root.
Now, if you can do the repair yourself it just requires the purchase of a digitizer. Which will come already attached to a brand new outer glass screen, and has the ribbon cable already attached. That will cost you around 50 dollars. I actually have the part you need, brand new, never used, but tested to be working that I was going to Ebay for as much as I could. I would sell it to you for 49 plus whatever shipping method you wanted. Let me know if you are interested

Another xda member I've talked to who was having a similar problem went into Sprint, and they said he had to unroot and go back to stock before fixing his phone. So you may or may not have to unroot if you decide to bring your phone in.
Also dont tell sprint you dropped your phone either.. otherwise they will tell you to go through Asurion and you gonna have to pay...

Live With Walkman Digitizer Problem

Hello everybody, this is my first post here, and I hope that I'm not posting in wrong place, if I did that, I am sorry. Now, as the title says, i have problem with the digitizer on my WT19i, the thing is that I cracked my original digitizer, but it was still working great, even broken as hell , than I went to a local mobile shop, where I've been told that the replacement brand new digitizer will cost arround 40 bucks, and arround 50 with their installation and it will be truly genuine part, but after I saw how they were repairing mobile phones with parts flying all over the shop, I decided to replace the digitizer by myself, i mean how hard could it be right? Turned to be a little complicated, but nothing special at all, so I replaced it with new double sided glue tape (don't know for the real name for it), and I assembled the phone like it should be, and I was maximum careful during the process (took me about 5 hours ), but when I turned it on, I noticed that the digitizer was not very precise, and sometimes was stuck in non-workable state, the hard keys work all the time, but the digitizer doesn't, it seems like it has mind of it's own, he decides when to work and how, so I opened the device again, reinstalled everything, cleaned ports with alcohol, and reassembled it very careful again, but still the same issue. Then i tried everything to eliminate software mistakes, but when I opened flashtool, and connected the device, it said "your device is not recognized", so I dissasembled the device, and put the old digitizer in, turned the device on, and imagine, the digitizer was working even it is with missing pieces from it, and Flashtool then recognized the device, installed busybox to the device ( I am sure that I had busybox before, and the device was working great ), but nevermind, I put back the new digitizer, and has been recognized in Flashtool, so I relocked bootloader and installed GB factory rom, v58, so the device is in the factory state right now, but guess what, the same problem is still here, tried hard reset, and many other stuff, but no luck. I tried to go to the shop and they told me that I didn't mounted it properly , I guess it's because I didn't pay to them to mount it, however, they won't replace the part and no money back .. I don't know exactly how to see is the digitizer genuine/faulty, or is some other hardware or software fault, but I've noticed that on the original digitizer it has some barely visible horizontal and vertical lines, and on the new digitizer the same lines are diagonally placed, and I can tell that the new part looks kinda cheap and low quality. So if someone has some kind of a solution, I will be greatly thankful to him. Please help me, because I become desperate about this, spended my money and now I am still in the same mess. sry for the bad english, it's not my native language, and sry for the long and exhausting post.
I guess you won't have luck
Just a short summary:
-Your digitizer was bricked
-You bought a new one for 40 bucks (instead of 50 including replacing in the shop)
-You opened the device and replaced it
-It was not working properly
-You put on the old one and it worked
-You went to the shop and told them it's not working, but they are angry because you tried to do it by yourself and so they didn't want to replace the new digitizer
-The new digitizer looks cheap and you can't get back the money...
Did I get that right?
Hmmm.....when buying original digitizer, make sure there come with tools included in the packages....if your digitizer only then make sure its not from china.....
it's not hard to spot original digitizer and cheap digitizer...original digitizer comes with warranty and the cheap one can be spot by looking at the ribbons....also original digitizer fits perfectly on any LWW while the cheap one will have a small gaps from the cover....
as for you problem, you should ask the shop if the digitizer comes with tools and if there a warranty for it...if it doesn't then you should just lets the shop replace the digitizer cause if somehow any problem came out then you can blame them

Yep, you got it.. is there any solution available for it or should I bent my tail and go buy new one from another mobile shop?
I finally solved the problem. I went to the authorized service, and they said that my digitizer is just fine, charged me 10 bucks, BUT, i was kinda suspicios about the repair, because they told me that the software was reinstalled and the problem was solved, which was ridicilous, because I personally changed and tried every possible software and kernels that I could find, so I tested the device right in front of them, holding other customers behind me waiting until I check it , turned out that the same problem is still present, I was pissed off, they were stunned that I found them lying to me, they took the phone back, changed the digitizer, charged me plus 30 bucks, and here I am, with finally fully working device. I just can't believe that Sony is allowing this to happen, I am totally disapointed in their customer care, and I just wanted everyone who has the same problem, broken digitizer etc. the original digitizer comes with the whole front cover, not only the glass, but the whole thing. I hope this post can help someone to not go through my pain and costs.

Please help with a possible S6 repair con.

Please can anybody with experience of galaxy s6 repair help.
A couple of weeks ago I turned of my s6 one night, next morning I tried to turn it on but it wouldn't, it was completely unresponsive, black screen no lights, the phone has never been dropped or damaged in anyway or been anywhere near water.
When it was switched off the battery was almost fully charged, so I knew it wasn't a dead battery but I tried the charger anyway. There was no charging light and the back of the phone near the rear camera got quite hot within a couple of minutes. I tried a soft reset but it didn't work.
So then I took it to a local phone shop for repair. The guy in the shop said that he'll send the phone of the workshop for a diagnostic. Anyway he called up and said the motherboard is faulty and needed to replaced. Now he phoned up again and the guy who is fixing the phone is now saying the screen also needs to be replaced, apparently the backlight is not working. Now I know amoled screens do not have any backlight, so I asked him what exactly is wrong with the screen as it's a amoled screen it doesn't have a back light, he said he doesn't know just the engineer said the backlight doesn't work. He said the repair would cost £149.
My question can a faulty motherboard damage the screen? is he what he is saying plausible or is he trying a con?
Thanks in advance for any reply's.

A faulty motherboard can damage the screen (in various ways). All screens have backlight (except for screens like the old Nokia 3310 had) so the layers of your screen might be damaged or have leaked since there is a fluid "sticking" the layers together. This is (obviously) not a software problem, but I would like to know if you were rooted, had any custom ROMs/kernels and did you have XPosed installed. How did you root and did you have a custom recovery?
All my statements are afaik (as far as I know) and based upon real life experiences, if anything I wrote is wrong, feel free to correct me as we are all learning .
Thanks for the reply, I hadn't rooted the phone, all I had done was replace the vodafone firmware to stock firmware as I was no longer on vodafone and wanted to remove all the bloatware, but that was many months ago and everything was working fine.
I just find it odd that a perfectly working phone can be damaged so badly for no obvious reason, it wasn't plugged into the charger, I just turned it off one night put it on my desk, tried to turn it on next morning and it was dead.
So does the repair seem legit to you? I am just a bit weary as I know how easy it would be to charge for parts that aren't necessary. Also is there anyway I could check if the screen has really been changed as the display on my phone was in perfect condition, not a single mark or scratch or any thing to identify it against a brand new screen.

Hmmm, okay.
If you have the right tools you can probably make a mark with a marker or something that won't damage the screen and then when they "replace" it you can check if it is still there. By the way, I don't mean on the screen but on that metal part on the underside of the screen. If you don't want to make such a thing because you maybe don't have the necessary tools, make a tiny scratch that you can locate but won't affect using the phone or not visible unless you really take a close look. If you don't want to do that you can take it to an official Samsung retailer or send it to them (this is probably the most recommended option).
Unfortunately the phone already at the repair shop, I got a call a few days ago telling me that the logic board was damaged and needed to be replaced, I agreed to that repair, now he called again today and said the display also needs to be changed. That's why I'm a bit suspicious, I can understand how the motherboard maybe faulty and may have died, but the display also? maybe he damaged the display when trying to change the motherboard or he's charging for unnecessary work or maybe he's telling the truth and the faulty motherboard killed the display, I don't know.
I was wondering if there's something in the firmware which keeps count of the number of times a part has been replaced or how long the display has been used for or a way I can check the date of the display manufacture without opening the phone.

Unfortunatly, no,but if the phone is working after the repair that means it is fixed! If not, they will give you a replacement since they test everything to make sure it works.
