I broke my phone screen digitizer/LCD/frame and replaced it with ebay one.
My phone booted up and working good but i cannot to disable the button backlights next to home button. it worked like a stock phone, my phone rom and 3rd party software has no control over backlight. any idea what i've missed ?
did the light turn on even on boot screen? if so, check the connector of your button. maybe there is some dirt or something on it so the electricity don't work properly.
Probably a bad connection of the sub key connector or a bad sub key flex.
Somtimes the soldering quality is very low

So this was my first breakdown of a phone...my brother gave me an HD2 with a non-responsive digitizer, everything else seemed to work just fine.
I disassembled it, accidently tearing the flex cable after it gets thin and goes to the volume buttons. Anyway...I replaced the digitizer...thinking I could just modify the volume via software controls, and stupid me had previously set the hd2 to boot into magicdlr always when the phone turned on. So when I turned on the phone I couldn't do anything because it would boot into magicdlr and I had no volume buttons to scroll up and down, and the option selected was boot into windows which was not on the phone (only cm7 was at this time).
Anyway...after getting a replacement flex cable, and reassembling everything, I couldn't get the lcd to work. Backlight would light up, but no picture, no sound, just a vibrate and the backlight turning on. I tore it down, triple checked all the connections, and still the same thing
So I tried a seperate lcd assembly, tripled checked all connections, and still same issue as the above paragraph, backlight but nothing else when I try to power on. I also retried the old flex cable (the one without the volume connector) and that didn't make a difference either.
My only guess is that I messed up the lcd connector on the mainboard, even though it doesn't look visibly damaged in anyway. Does anybody have any other ideas/suggestions?? I would love to get this up and running as its been my first smartphone project...I've done lots of works on desktops and laptops but never smartphones.

This is my suspicion too!Even not visible at first sight, try again with a magnifier!
Good luck!
Hey guys, I was just using my phone today like a normal day, and my phone's power button just stopped working. I doubt its software, so is there anything I can do to fix this? Any guides in particular?
edit: the button has randomly started working again after I pushed it in a bit without opening anything, but I suspect theres dirt accumulating in there or something and just making it hard to work. I'd still like to know if theres a way i can get the power button out, clean it with a q-tip or what not and get it back in all safely.
Sorry to hear that, bro. Judging from this Vibrant tear-down thread http://forum.xda-developers.com/showthread.php?p=24155781, it looks like the power button is accessible after taking off the main back cover ... but I can't really tell from the 2nd photo (looking at it from my phone / Tapatalk right now, and the zoomed resolution is not very good).
Hope you get it figured out, or maybe (in the meantime) use a power button widget / shortcut?
( not to make light of the circumstance ... but maybe make sure you're using the right "towels" when you wipe down your phone. Its always easy to blame dougie's special red apk. )
Hey xriderx, it is pretty easy to replace the power button ribbon. Just dont tear the pad off the board like I did. I found the ribbon online for about $10. What you are describing is exactly what my power button did before going out completely.

How can you detach the power button ribbon and replace the by the new one? do you have to solder or anything ?
Yes it will require some soldering. Maybe some desoldering tape to remove the old ribbon/solder as well.
Hi guys, first post. So heres the problem. My HD2 screen is not glued properly to the base of the phone and it has a little space between them at the bottom right corner ( next to the Power button), whenever i press the screen to close the gap the phone freezes, and i have to remove the batery. It is getting really annoying couse i cant even put the damn thing in my pocket without it freezing. The hardware keys dont even work i just have to restart it. So my question is does any1 know of this problem and can he/she offer a way out?
Sorry for my english. thanks in advance
Sounds like it been opened before & had not the best assembly.
Would imagine hardware button ribbon is torn or pulled out of socket hence no buttons.
freezing issue could be down to issue with digitizer ribbon or button ribbon or worse ?
Do you have any issues with screen touch & do you know full history of the handset.
If black Void sticker is missing from case screw near battery pins then you know it been opened & most repairs including so called specialists are poor from ones I've seen.
I know this is the last thing you want to hear but if it were my device I'd take it apart and redo the assembly myself. Theres plenty of how-to videos with detailed steps. Hope this helps.

Ok, so I recently just had my phone repaired, cracked screen, etc. I just NOW realised my proximity sensor is defective.
I go to make a call, screen goes black, pressing the power button allows it to come back on for like, 1 second.
I just now set it to hang up the phone using the power button.
I am NOT using a case or screen protector, and I used an app to test the sensor, and it's not moving whatsoever.
Is there a way to disable it so it does not shut my screen off?
Edit: I finally figured out how to configure the "Proximity OffScreen Lite" app to get it to work.
I have replaced the screen, LCD and frame on my VS980 due to dead sections of the screen. There were no problems swapping everything over to the new frame. The phone seemed to be working perfectly until I went into a dark room. When I am in a room with little to no light knock on does not work and if I press the power button the screen times out while I am swiping the home screen. Which component will cause this problem? I double checked each piece before reassembly and everything appeared to be properly installed.
Have you tried the motion sensor calibration? For me i press the power and volume down button quickly and it unlocks. Have you update the touch firmware?
I did the motion sensor calibration and it didn't help. the dialer codes I have found for the vs980 don't get me into the service menu.
I dont know for sure but i think its the hardware problem as in replacing the new LCD and all, but ya that be expensive to buy new ones just after buying a new one. If it still have warranty maybe replacing it perhaps. If the service menu dont work, i dunno.
Your proximity sensor may not be plugged in all the way.
How does the phone work while making a call?
Test it first. If the screen stays on during a call while the phone is held to your face, open it back up and double check all connections.
Unplug and replug the screen, digitizer connections, selfie cam and proxy sensor connections then test again.
The proximity sensor which is top left when looking at the front display. Smush and/or rub with your finger, then try to unlock again. I have to do this frequently.
