Hey guyz. My core 2's digitizer was damaged from a dog bite. So i tried to change the digitizer by myself. There is a connector which the flex cable of the digitizer connects with the lcd. I broke that small square shaped connecter. Now the phone turns on to lock screen. Bt after about 10 seconds it hangs. I cannot connect it to kies. I need my contacts in the internal memory. What do u think i should do ? Does the phone needs the digitizer to work properly. I meant is that the reason it hangs ?
Hi
Thanks for writing to us at XDA Assist. I think the only thing you can do is repair/replace the part that was damaged. Yes, the phone requires all parts to be working properly in order to function. If you're not confident enough to undertake the repair yourself it might be a good idea to take it to a professional.

I purchased a Tornado a little while ago and didn't vet it properly first. It was descibed as having a cracked screen which was actually a cracked LCD. I have replaced but I get only a white screen on boot. The unit works fine other than this as I can connect via BT and USB. I have been able to verify that the file system is fine. I am assuming water damage and am going to try the DISTILLED WATER / COOK solution, but before I do...
Now, being aware of my status here, I can only make an offer to anyone with expertise on this. If anyone thinks this a problem they can resolve I am either happy to sell them the phone, take their advise and split the profit when I resell it or send it for paid repair.
Any takers?
Thanks for taking a peek at this thread.
P.S. Please, no remiders of my remiss behaviour when purchasing it. I have already kicked myself half to death, thanks.
A white screen normally means the ribbon cable to the lcd is not inserted properly, make sure the white lines on the cable and the main board are lined up. I've had the same problem.
have had the same problem with htc tytn, p4350.
after reboot its okey again
hi i replaced the digitizer following a guide i found online
step by step and being really careful.
when i finish the phone wouldn't turn on you can feel it vibrates once but that's all.
y tried going to the bootloader but it wont work.
i search online and found a couple of posting on forum anout people having the same exact issue, but without answer.
y re-opened to verify if i missed something, 3 times, but everything was fine except to the very last time i broke the ribbon for the track pad.
when i plug it to my laptop my charging light comes on for 3 sec then goes off and back on for 3 sec. and remains on a loop .
could it be that it needs to be reset some how?
i was thinking maybe i fried the board with my static, but i doubt it.
please help.
thanks in advance
I can suggest that you need to make 100% sure the ribbon cable for the slider is not dinged or has the black coating worn off. Other than that I suggest that you make sure the connection from the LCD (not the digitizer) didn't come loose. Those Jawbone connectors can be a pain to get in correctly. Also even though you got the connectors in right you need to make sure you didnt accidentally nick or fold the ribbon.
Also make sure the socket connector on the main board is on correctly. It may seem on but there should be a tactile snap when it goes on properly. The connector I am talking about here is the one that you pull off before lifting off the slide flex cable to take off the mother board.
One last thing on that connector...make certain none of pins got bent either.
I have done many different repairs of phones so those are the things I would look for. I havent repaired 4g slide yet bit have done other HTC phones and the similarities of the 4g slide motherboard and the Sensation's are crazy. It really is mostly a sensation with a keyboard and smaller screen.

yeah i know which one you re talking about, i'm going to take it apart again now. the only think i see wrong is,when i tried to separate the lcd from the the casing i might over heated it with the dryer, or i slide a credit card in to separate it and the flex got a little torn but i don't see any cracks or damage on the ribbon, but if that was the case the phone would turn on and just don't display anything, but is not booting up at all.
thanks for your reply tho. i appreciate it
nope, i just re-checked everything, and is the same thing. is someone want to buy itas is pm me.
Hi all,
A follow up to my enquiry here about a badly damaged phone: forum.xda-developers.com/google-nexus-5/help/transplanting-main-board-data-recovery-t3253789.
I ordered a second Nexus 5 with the intention of transplanting the first mainboard into the second body, only to discover the first motherboard has a damaged daughterboard connector from the initial accident. The daughterboard connector/pins (?) aren't attached to the mainboard anymore. Photos here (that's the disconnected socket/connector next to the board):
cl.ly/142v473d2s17
cl.ly/33461J0K1Q2d
cl.ly/2S190F1v2M2c
In spite of the missing socket, I actually tried connecting it to the rest of the phone and powering it on anyway - no luck however. Didn't budge after holding down the power button. I can confirm that the rest of the second phone works when I plugged it all back together with it's mainboard.
Questions then - is it possible for a professional (presumably) to reconnect this and get the board back up and running? Or is my motherboard and data completely gone at this point?
I realise the solution probably won't be cheap at this stage, however I really want to recover some of the data off that phone and I'm just hoping that's in some way shape or form possible.
Thanks for any advice. Having a bad run of luck and really hoping for a bit of a holiday miracle with this now...

Hi
Sorry for your problems. To help yourself understand how your Nexus 5 hardware is put together you should take a look at the youTube video posted by LE55ONS "Nexus 5 Teardown" -. Just do a search for LE55ONS in YouTube. He has posted many very well made videos on how to repair smartphones.
It will show you every aspect of the hardware.
I hope that helps you

Thanks but this doesn't really address what I've asked regarding the damaged connector.
I would say, in theory it should be possible to reattach that connector with the proper reflow equipment, but it rather depends on how much damage was done when it was pulled off the board. If it is just the solder that let go then not so bad, but if any of the copper pads/traces on the main board stayed attached to the connected when it got torn off then it becomes a much more difficult repair. The puzzling part is even with that connector removed you would think the main board would still be able to power up, with obviously the ports attached to the flex board not being available so that makes me wonder if perhaps other damage has been done to the main board? You could confirm this by seeing if can power up the other working Nexus with that same connector unplugged. If the other one powers up then that's a pretty strong indication you've got additional damage beyond just the torn off connector.
Hi there, i'm French and i bought a motorola photon Q on January 2015. Today, the phone goes into the screen blacklight issue...i ask your help because i don't know what i have to do...a priori it's a well known issue on photon but i didn't success to find a solution...
The phone's screen is black but the phone is in fonction, i can take pictures or receive SMS...just the screen doesn't display anything... i tried to maintain power+vol down buttons but when i reboot i don't have the motorola logo, as instead the screen display a cloud of dots white, black, red during few seconds and turn on black screen again...i can't have the motorola red logo, i don't know what to do...if i have to replace the LCD or not ? re install a ROM by PC or not...the phone is out of order ? that's the flex cable issue ? i don't want to buy a flex cable or a LCD if the problem doesn't come from that...i'm block and i hope you can help me...
Thanks in advance
Did you lose LCD or backlight? I don't know if only backlight could be broken.
If your LCD is completely black and nothing at all, I suspect your flex cable is gone, which is a fairly common problem of this device.
btw, Did you buy a new one? it mostly takes +2 years before you see any problem there, though.
Thanks for the answer,
i lost the LCD, it's completely black...nothing...
i unmounted the phone, check for the plug and i noted that the flex black cable is damaged, the surface becoming bright grey with friction of the keyboard open/close mouvements... Maybe a short-circuit have also damaged the LCD...i'm wondering... i don't know what i have to order... simply the flex cable ? or flex cable + LCD ? i don't want to buy some pieces if they are useless or the phone still goes out of order with...
I used to use all the time, it's my computer, my phone, my organizer... it's maybe the reason that the phone went out of order quickly.
Where can i buy this flex cable for reasonable price in Europe ? with sending and custom fees that cost more than 50€, it's very expensive for an eleven mounths cable lifetime :/
I have to remind you that replacing a flex cable is not easy, unless you are comfortable at these things.
Why don't you get a decent used one from ebay or something? replacing the mainboard will be a lot easier than taking your screen apart.

I think i can, i've already repaired hundred times my old droid 2...
i can't buy an other cause it's too expensive...this one already cost me a kidney with sending and custom fees... furthermore in Europe nobody sell this phone... i must replace the flex cable, it's less expansive :s and even like that i think it's too expensive...50€ for a cable it's a power abuse...
Do you know a website that sell spare pieces in Europe ? maybe it will be less expensive to buy it directly here
thanks a lot
Hello everyone..
I've just replaced the battery for my galaxy S6.. and for some odd reason the touchscreen is not responding anymore. I just disassembled my phone again to see if i disconnected the connector for the LCD/Touchscreen but that is fine. i even disconnected it for 5 minutes to see if that would resolve this issue but no result..
Can anyone please tell me what the problem is? does my phone need a full reset or is there maybe something i've messed up with the motherboard? When i done unscrewing the 13 screws and then continued trying to disassemble the body from its enclosure i did get my "knife" between the LCD and the motherboard at the top of the phone.. could i have messed up something there? Is there any cables or connector between the LCD and the motherboard... if so i have to probably heat the LCD and take it off the body/motherboard.. so please tell me there is nothing between the LCD and body/motherboard..
i hope anyone can help me out here... i really need my phone. the battery is fine and the phone boots up. When i place my thumb on the home button even works! but the screen doesn't...
Thanks in advance.
