I have heard that the battery is kept in between the motherboard and LCD for this model. It seems in general that HTC wants to make devices hard to unlock, root, and repair.
Has anyone needed to replace the battery? If so, how was the experience?
As you can see on this video - goo[dot]gl/tJs8d - the battery is easy replacable, although i could't find any service manual for this phone. But it's possible in easy way to replace battery.

I am one of the "lucky" few who have a phone that reboots when using GPS Navigation and now pretty much while doing anything intensive on the phone. When it reboots I get the 5 vibrations and flashing green LED. A battery pull and sometimes a long wait period are required to get it back up and running until it chooses to reboot again (same cycle). Flashing back to stock and un-rooting does not help, nor does flashing a different radio (I've tried them all). Anyway, this problem is all over the net and it seems the only cure is replacing the phone. I don't have that option because I have no warranty.
Enough of the background....
I am planning to purchase a 'for parts' Inc off Ebay. There are several where the screen is just broken but everything else supposedly works (clean ESNs). I intend to buy one of those and basically transplant the motherboard into mine. I've had mine apart already, so I know I can perform the task.
My questions...
1) What if the 'parts' phone I purchase has a SLCD screen? I plan to use my AMOLED screen. Would it work to use my AMOLED screen with a motherboard from a a phone that currently has an SLCD?
2) Any other reasons my proposed methodology won't work? I don't plan to replace anything that required soldering, so this should be pretty straight forward.

The AMOLED device won't work in the SLCD device because the drive electronics integrated into the board for the AMOLED are different.

Thank you. That's just the information I was looking for. <mashing the ty button>
My Dinc had the same problem as yours. Basically the ball array that connects the processor to the board is failing.
Take a look at this thread..
Solving the thermal problems of HD2 or other snapdragon
I heated my processor and managed to save my phone. It is definitely a last ditch effort, but if you are going to buy another motherboard it might be worth a shot.

Wow... That's pretty hard-core phone repair! Just...... Wow.
I had done just the basic pc builds & repairs until I attempted this. It was a little intimidating, but I love my phone again!
A friend recently sent me her "retired" Galaxy Note II. She replaced it because at some point the screen stopped turning on altogether, but she still wanted me to see if I can salvage it somehow. I've tried, with no luck, and searches on the topic don't seem to suggest any solutions other than the fact that it may be a hardware issue. While I can accept this possibility, I'm really hoping that it is not the case because at this point I don't think it would be worth investing the time and money to buy the parts, learn how to replace them, and attempt it. If anyone has any ideas I'd be very grateful. Here are the symptoms:
The display NEVER turns on. It is in a constant state of pitch black.
The sounds are working fine. When I get an email, for example, it notifies me.
The hardware button works
The software buttons do not work
Upon connecting the device to a monitor, keyboard and mouse, the monitor works, however the keyboard and mouse do not. (I use the same monitor, keyboard and mouse with my Galaxy S4 and they all work fine.)
Touch interaction with the screen is working properly. Using the monitor, I am able to use the device, but it is very tricky, as it is simply a matter of trial and error. I tap on a black screen and have to look on the monitor to see if I hit my target.
The device is on the stock TouchWiz that came with it, and is not rooted. Since I am pretty sure that doing any mods without a working display would be more difficult than I could tolerate, I opted to take an OTA instead, despite the fact that it may make rooting and flashing ROM's impossible in the future. I hope I didn't screw myself by doing that but I had to make an executive decision. Here is what I've tried so far:
Factory reset
Update to the latest software (Android 4.3)
Pulled battery, held power button for 10 seconds while battery was out, replaced battery and powered device on.
I'd greatly appreciate any suggestions. Ideally, here is what I'd like to happen: get the display to turn on and restore functionality to the software buttons. This may not be possible without replacing some hardware components, which as I mentioned is not an option, but if it is I'd really like to give it a shot. Thanks in advance for any suggestions.
My initial guess would be a digitizer failure...
A phone drop or water damage can easily render a phone dead...
You have the option of replacing the screen and digitizer at a cost of about $225.00 for the needed parts...but it's still no guarantee that the fix would be 100% successful...
My honest opinion is this...
Given the unknown history of the device...you are taking an expensive chance in attempting a repair...
And given the age of the device....the repair if performed by a qualified repair service would push the cost very near to the overall value of the device...
For the same dollars spent...you can obtain any number of working devices and save yourself the hassle...and the unknowns associated with a repair that will likely work...but again may not...
You are of course free to attempt the repair...but....
The skill level needed to perform a "proper" repair of the device is high...and you would need to study up on the process extensively before cracking open that case...
If I were in your situation...the choice would be to sell the device for parts....and put that cash back into a working device...
Others will chime in I'm sure with their recommendations....but I would choose to move on...g

Thanks for the reply, and sorry I didn't see it sooner (I always forget to subscribe to threads). I figured this was probably not a fixable problem (at least not easily/economically fixable). But I wanted to see if there were any quick fixes I could try, and it sounds like there aren't. With that said, if anyone does want it for parts I'd let it go for a reasonable price (considering the damage and lack of functionality) through Swappa. (Sorry if I'm not supposed to make these kinds of offers here, if that is the case I'll gladly remove it.)
Hey guys,
Just signed up to ask a few questions, a very good friend of mine had her phone (T-mobile Samsung Galaxy SII SGH-T989) run over the other day. Needless to say she is not very tech savvy. She has a new S4 now. Now the problem is, that being she is not so tech savvy she didn't back up (ever?) So i am looking to somehow recover lost pictures and contacts if possible.
Now I have a small background in building computers and taking stuff apart so I agreed to take a look at the phone. The screen is shot. but besides that the other internals look fine. Nothing is broken as far as i can tell. When I plug the phone in with the battery nothing comes up at all, except when i leave it plugged in for a little bit the LED under the camera will flash about once every minute or so.
So i guess the question i have is did the motherboard somehow short circuit when it was run over? Has anyone had experience with a situation similar to this before?
And is there a way to get the phone on long enough to recover the lost info?
Help would be much appreciated if possible.
Justin
As phones don't have an actual hard drive, I doubt you can recover anything from a phone that isn't running.
Sent from my N5, N7, Moto X, G Tab 3 or S2.....
This is not easy, but can be done. I have done similar recoveries several times…
You’ll need:
1) The equipment & ability to remove a surface mount soldered chip, and re-solder it onto another board *without* damaging it.
2) Another identical phone to host the transplanted chip.
3) A service manual, or someone with intimate knowledge of the device, to identify the correct chip…
Note that if the pix were encrypted this will not work…
So, my G3 is completely dead, failing to boot. I know the screen and battery are absolutely fine as I get battery warnings displayed when no battery is inserted or when it's actually dead. I've decided the cheapest option would be for me to replace the main board and have found an exact replacement for my model (16GB, 2GB RAM, D855).
Seen a teardown on YouTube and having taken other devices apart before (once worked for LG themselves) it looks easy enough for me to do. My only question is, will I experience any problems replacing the MoBo or should it be a simple process in regards to getting it to boot?
Sorry if I haven't bee specific enough, I'll try to explain as best as I can if anyone wants to know more.
I've seen some tutorials saying the G4 is easily repairable, but I have some specific questions about repairs. The WiFi module on my phone is completely dead, and I want to try to replace it somehow. This guide shows where the module is, and what kind it is. Has anyone attempted a similar repair? Is it even possible? Where did you get the spare parts? Should I just try to get a whole new logic panel from a different G4? Does anyone have tips?
I tried adding links to the guide and the specific chip, but the spam filter blocked me out.

It's going to be very difficult to get a single broadcom chip. Most of the time they're only sold in big quantities exclusively to corporate bodies or educational institutes. But let's say you got one. I'd urge you to use a BGA station or have it replaced by someone who has experience in using such a device, OR, do it like this guy here. It may show an eMMC replacement but the procedure is exactly the same.
Getting a new mainboard is also not very easy. Not only is it very difficult to find one, most of the time, smartphone logic boards have to be rewritten with the correct IMEI/SN/ESN or whatever. If you're lucky, you'll find a seller that offers such a service for a small fee.
I don't recommend getting a used mainboard in any case unless the seller is a trusted dealer. In such a case, you have to take care of the IMEI and SN stickers on the back of the phone. Make sure you attach them on the corresponding devices.
