Disconnect the Wifi Cable (Black One), Rear Camera, Front Camera.
Now with just the logic board, place it on a surface that won't melt.
It should look like the picture below. Warning don't take off anything else

Turn on your heatgun and apply left right motion only concentrating on the cpu metal plate for around 15 seconds.
Do the same thing on the opposite side of the cpu plate.
Let it cool down for around 10 minutes.
Put it back together and it should work.
I did it atleast four times, first time it worked but failed after few minutes.
Second and third time was not working at all.
The fourth time I did it, it was working.
It's been a while and it still going.

I don't have a heatgun, could a hairdryer work?
Thanks for your post. Hairdryers go up to 140 degrees. Could this be enough? If not, can you share what setting the heat gun should be put to for this repair? Thanks again.

8525 White Screen of Death - Is there Hope?

Ok so I have the fabled white screen issue on an 8525. When it first occurred I searched and read all the write ups, decided I had the ribbon cable issue. Took it apart and simply unplugged and replugged the ribbon cable with great results, no more white screen.
I repeated once when it came back after being bumped around, again with positive results...but this last(3rd)time instead of it working I now get white screen 95% of the time. I re-notched the sliders the first time, and last time.
During the 5% it works I noticed the charge light would correspond to it going white.This never happened before...
Example:
When OFF - Connect charger, Red light for 1 second, then nothing=White screen from power on
When OFF - Connect charger, Red light for 1 second, then orange charge indicator = normal startup
When ON and Working - Connect charger, no light, no charge - reboots to white screen
When ON and Working - Connect charger, orange charge indicator, reboots normally.
There is no heat or noticeable pressure on any parts, everything seems to fit normally.
It does boot normally with screen white.
Any ideas? I really don't want to give up on this thing, is there any hope? or just ebay it for parts?
Thanks

same problems here, if someone could just tell me what parts to order, cause I have no warranty (ordered over ebay). I tried both the instruction that has chinese fonts on the page , and other from R&R, no luck, white screen all the way..
I had the WSOD and took it apart and reassembled a few time. The 3rd or 4th time the screem came back, but now it is shifter to the right around 1/4" or so. I mean there is just white along the left edge, then the normal screen/color starts and is cut off on the right.
Does anyone know how to correct that, is it related to the same flex cable or is there something else I disturbed?
mine will fade to white.. then i just push the power to put it in standby, then push power again to wake it back up and back to normal.. it rarely does it but still annoying...
If You Ordered From At&t
I had this problem about 2 weeks ago!!!!
I thought it was a fluke!
Anyway, walked over to 43rd and Lexington (NYC FOR THOSE WHO DON'T KNOW THAT MANHATTAN IS THE CENTER OF THE WORLD)
and they gave me the EXCHANGE HOTLINE for at&t.
I called them up, told them my screen is fading to WHITE and the lady sent me a new or referbished phone.. i dont even know.
Just so you know, i ordered my phone on AMAZON with a new activation. its covered under the MANUFACTURERS warentee for a full year from the date of purchase... so is the REPLACEMENT PHONE... but not from the date of replacement, just the date of purchase.
did anyone get deeper into this yet? I got a 8500 (need those without camera) from ebay USA, already with white screen. After reading here, that this is mostly an issue with connectors, I bought it, disassembled it and reassembled it, though still white. Should I give the contacts a treatment with contact-spray? (there's a tuner spray that doesn't leave residues) Or is there something broken within the ribbon cables? Seller said it has been dropped (but he also said, he didn't want to open it, while it clearly has been opened, one screw missing and warranty seal gone). It ssems to boot up normal otherwise, I hear a sound after the boot process, so probably this isn't a software issue?
Edit: another thing I noticed: When I run it without any keyboard connected at all, it's also white. I then connected the dpad again, and I could see a hint of the at&t logo in the lower part of the screen. When I pressed around on the back of the dpad a bit, all LEDs would go on/off... Sound to me like the dpad has gone bad, possible?
Edit II: Got it. Using a 20x eyeloupe I found that the PCB of the DPad is broken under the little chip on it. Now I just gotta find a dpad here in germany, but I assume those Hermes' are all equal...
hello
where can I get manual (if there is one) for disassembling hermes. link in wiki does not work.
thanks
this worked good for me

Anyone know if this applies to the 8125 as well? I've got a flickering white screen. I had dropped my phone a few weeks back and cracked the LCD. Replaced it with an OEM LCD - it worked fine for about 2 weeks and then just suddenly went all white. Phone still works, I can still get calls - just can't see who is calling.
I don't recall that the wizard had the same problem... Though from a logical point, it seems that there is an issue behind white screens and the thumbpad being responsible for it, so it may well be the same thing. Perhaps just disassemble the wizard (there should be a howto too) and check if theres a similar connection from mainboard to thumbpad circuit.
Is there a disassembling manual for a imate k-jam that anyone knows about?
Here's a website with a video manual i found useful...
http://viralelectronics.com/category/howto/page/2/
Figured out the problem...
The only reason I figured out the screen goes blank is because the motherboard loses connection with the screen when you slide the keyboard out...try this out and see if the screen comes back...
put the screen on sleep mode (no white screen)...then slide out the keyboard and tilt it a little hard after pressing on the screen and put the power on. if it doesnt work try again it might take some pressure and power to make it work...be careful not to put too much power but as far as I went, it's a very sturdy cell.
alternately, slide out the keyboard in sleep mode, and press all the buttons really hard and then try to press the power button (press more towards the space bar because that helps)...if any of this works and the screen comes back on even just for a second...follow the following
Go back to the person who gave the link to the site with opening the HTC instructions and follow through and clean the whole phone up from dirt around the screen and such...you dont need to put those rubber things or whatever it says to put on the screen...then when you are putting it back together, press hard on the wire connecting the touch screen to the motherboard. I suggest sealing it with a good tape...and then you are good to go! I did it but it had a few glitches...the screens contrast sometimes goes awry but it is still visible and responds to touch. Also, the physical buttons work as well!!
Good Luck and do it at your on risk.
Have any of you tried this? http://forum.xda-developers.com/showthread.php?t=321163
hope the best
i tried this and it worked for me. i also pressed alil hard around the d-pad and heard a pop. i think it poped back into place.
thanks

i still have this problem.
fixed my wsod
I noticed a few days ago my 8525 screen went white, rebooted and it went away. Today it came back, but would only go away for a few seconds and then back to white. After reading some forums I decided to check the connector. I took the phone apart following this site as a guide. I removed the connector on the board side and cleaned the contacts with a qtip and denatured alcohol. Phone has been perfect for the last few hours, no more white screen of death. I didn't mess with the connector on the LCD side, just the board side. I'm a computer tech and I found it quite annoying to disassemble, but I managed without causing any damage, however, I'd rate the job at about a 8/10 as far as technical ability.

i agree that this is one of the first things to try in curing the white screen issue. Others may find their problem runs a little deeper and the contacts on the d/pad chip are broken. An improvised cure which may not be very permanent is to place a little padding on the surface of the chip as described here:
http://forum.xda-developers.com/showthread.php?t=321163
If you have appropriate heat gun equipment you can re-flow the solder on the d/pad daughter board - but remember to remove the sticky key pad layer or you'll cook it!!
I regret that I'm closing this thread because we have several "White Screen" threads and the questions and answers are being spread all over the place.

Habitual screen crackers, read this!

I've replaced my wing's screen three or four times now, and I've found an easier way to do it.
Ironically, the last time I cracked the digitizer, I had the phone in my pocket and was reaching across a pool table to get the aluminum hard case for it.
Anyhow... if you've done this then you know what I'm talking about, and if you haven't, then follow these instructions when you finally do replace it.
Leave two screws out of the back of the phone. You know the ones, those that you can seebut just can't get a screwdriver onto. Yes, those two on the back of the screen part of the slider. Put the two back on that you are able to get to when sliding the screen out, but not the others... the snaps around the bezel will hold it on tight enough anyway. If you haven't been there yet, I'm sorry, you need to go through the 30+ minute headache process first, and you need to figure out that the loose rubber piece that landed on the desk goes to the microphone port.
So the last time I replaced it, I left those two screws out, and this time I just had to remove two screws... then two more. Why two more? Here's an important part of the tip... when you take the front off, and you need to disconnect the ribbon cable, they don't flex enough. Remove the screws holding the front panel buttons (d pad) that's just two more screws folks, a total of four. Versus I don't know... twenty? Now if you have an assistant it will be easier, but possible alone... slide the screen halfwayopen. that gives you the maximum amount of ribbon cable exposed and you can easily get to the back to reconnect the new screen's ribbon cable. (disconnecting is way easy)
Five minutes work time, and you're back up and running.
The best part of this process? You can put the battery back in as soon as the ribbon cable is connected and make sure everything works fine before re-assembling!
Damn I'm good!

[How To] Fix Blank/Garbled Screen Issues

Last night my Transformer started acting up. I was browsing Facebook, and then I hit the back case just right while setting it down and the screen went all green and purple (garbled/glitchy). I kept pressing it and eventually the screen completely shut off, though the backlight was still on.
In this small "how to", I will show you what you need to reconnect to get the screen back to operational status.
There are two sets of tear down pics for the TF that I found. One comes from XDA member hybridau, found here and the other is Tech Republic. I'll be linking to pics from Tech Republic along with my own as they were a little more informative.
Take the device apart. Torx T5 is needed for the bottom. Work your way from the end they show in the picture here. Then, press down hard (but be gentle ) on the side until the bezel disconnects from the base (pic). Next, gradually work your way around until you get to the dock connector. I used a thin piece of plastic to go around the edges, but I've heard a guitar pic works well (I don't own one). Note: for me, the dock connector was the most difficult part of the bezel to remove.
Remove the four screws around the screen area and then the three around both long sides (six total).
Turn the device over (screen facing down) and remove the back cover (pic).
Now, look for the piece in the pics below. The ribbon needs to be pushed all the way in where you can't see any of the connectors. Mine was visibly out of place. It won't be fully out of place. I used my fingernails to gently move it back into place one side at a time. You may want to try something else... it's not the easiest thing to move back since there is tape that was/is supposed to hold the thing in place.
Full device view:
That's it! I turned it on while it was apart to make sure screen worked, but that's up to you. Put it back together the reverse way... much easier putting it back together. I put the bezel back on the opposite direction I took it off.
Little background on the device:
The device has been dropped a few times while in a protective case or when tossing onto the bed (no visible signs anywhere on the device -- seriously, the device was thrown and dropped more during shipping than it was in my possession), so I called ASUS and they issued an RMA on it. Of course, if the issues are caused by you (dropping), you have to pay. Regardless, shippings going to cost some money.
Thus, I took it upon myself to fix it. I knew it had to be a ribbon that was disconnected because I doubted it was any kind of screen problem. I had also read in another thread here that that when they sent their TF off the return said all the techs did was reattach the ribbon. What a waste of time, money, and effort?!
Anyway... hope this helps someone with the same issues I had!
Thank you very much for the details. It doesn't effect me but I have read several threads where people are having this issue. I am asking a mod to sticky this for awhile so it doesn't get lost
Thanks! I just hope it helps someone else contemplating doing what I did. I almost wasted time and money sending it to Texas for repairs!

I am so dumb. Dead WIFI/BT. List of what I have tried, what can I do?

Passed out with a protein shake in one hand, brand new Oneplus 2 in the other. Woke up with the OP2 and my pants filled with a thick vanilla protein pool.
I'm special.
I wipe the phone down- not really knowing how bad I had damaged it, just looked like the screen had some of the shake on it at first glance.
[FYI: the phone was powered on it while it soaked in the protein pool for 5 hours- and stayed on. ]
I flick the notification switch and yep, still running. Immediately powered it off (was also VERY hot). I almost considered it a wash and decided to wait for another invite and keep it for parts, but I want to try to repair it.
Knowing my warranty doesn't mean jack at this point- I immediately removed the bamboo back cover, it looked as though looks like someone spilled ice cream all over the backplate and body okate, this thing definitely got a bath.
Voided the white sticker screw along with the 18 others. Removed the ‘un-removable battery’. Then let it dry (big ol’ bowl of rice). I'm not sure made it worse or better as the protein shake was very dense- the internals had hardened delicious vanilla plaque caked all over upon inspection of removing the back plate.
Visually inspecting the shame, the headphone jack had allowed the shake to trip directly into the mainboard, now half way crusted over. Areas of the part of the PCB I could see looked a little bit wet- I dabbed them with an iso pad, then dabbed with lens cloth and decided to let it sit in a rice-bowl again for another day or two..
Day 5 of drying... at this point, I decided ‘screw it- let's see what works. Put the battery back in and powered it on. LTE-working, LCD/touch/buttons, working.. No Camera/WIFI/Bluetooth/Speakers/GPS do not work at all. No MAC addresses for WIFI NIC or BT NIC.
Oddly, text/system notifications created output but it didn't seem to come from the speakers on the bottom. No music players could output anything through the main stereo speakers. Calls (earpiece and mic) worked fine.
I sigh, and stare ate the mess of a brand new OP2. It half-ass works. I almost considered it a wash and decided to wait for another invite and keep it for parts, but I want to try to repair it.
I took all of the internals apart minus the LCD/Digi.
Meticulously cleaned for around 2 hours using iso alcohol for the frame edges, headphone jack, and various other parts- also used a PCB cleaner that is safe for use on various plastic polymers/butyl rubber/whatever.
Got the main PCB and bottom PCB nice and shiney, however the items covered by the poriforated EMI shield I cant get into to clean without either a dremel (yikes) or somehow bending/cutting the top off. Any tips here? I believe the WIFI, BT, and audio amp are stored under here.
At this point, If you looked at the internals you wouldn't notice anything had been spilled into it (other than the water-tamper stickers being red)
I take a blowdryer to the PCBs on low and the interior to quickly evaporate the iso and PCB cleaner for about 15 minutes.
I waited about 3 hours before putting the battery back in.
Now I have working headphone jack, speakers, both cameras, and GPS (and LTE/GSM has always worked so that's fine too). Now the only problems are Bluetooth and WIFI.. again no mac addresses and they do not allow me to toggle them on.
Full system wipe to stock, and I mean ALL the way stock. Wiped the heck out of everything except the boot loader and even flashed the stock boot loader back on. Still cannot enable WIFI/BT.
Does anyone have any suggestions? Word around here is that you cannot buy the logic board, and the only other options is to buy another or find someone who cracked their screen and use their PCB.
Wow. Just wow.
I'd say, just try another round of cleaning and drying.
You might be lucky 3rd time.

Backlight no longer works after getting wet.

Hi guys on Monday my Moto X Style fell into a bucket of water ( I was ill) I promptly snatched it back out removed the case (Supcase Unicorn beatle). At first it was on and working fine and I wiped and shock the very small amount of water on it off. Then about 5 to ten minutes later the screen started to flicker, I turned it off and put it in a sealed bag of rice for 5 days. Upon taking it out on the 5th day the backlight isnt working at all. I've used light at an angle to test the screen and everything works fine, touch responds, no outlines etc, only the backlight. My question is, is there anyway of fixing this short of replacing the entire screen? I've heard people suggest cleaning the cables with 90% alcohol, is this a viable solution? I'm willing to try any feasable method before I get a new screen. Thanks in advance.
Well, you have to take it apart to clean cables and to replace the screen. So if you don't need the phone (you have a backup) I would take it apart and clean cables and see if that works. If it doesn't, leave it in pieces and order the screen and replace it when it gets to you.
