No power after repair - G2 Q&A, Help & Troubleshooting

Hi, I bought a G2 (Verizon model) off eBay with a cracked screen. When it arrived I plugged it in to see if it would boot, it had a red LED come on and windows made a USB noise but nothing was displayed on the screen. I waited a few minutes and tried to turn it on. It said it was on 4% battery and not enough power to boot. Fair enough, seems to be working. I unplugged it and took it apart then transplanted the parts into a new LCD I got from aliexpress. Was a pain in the ass, that glue and tape is tough to fight with but I finally managed to wrangle free all the parts and get them over.
Put the phone back together and now when I plug in the USB cable there is no LED and no USB noise. I'm sure I plugged all of the parts back in. I don't know what a part at the bottom near the charger is though, could it be as simple as this part being responsible?
Here is an album of my phone if anyone can spot anything I missed

HTC HD2 Is not turning on, only turns on sometimes whats wrong? need help extremely!

Ok i got an extremely bad problem
i brought a hd2 from ebay with a fault, which was the person said he dropped the phone and the screen cracked then he replaced it with new screen and digitizer, but he said after he did that the phone only starts up sometimes, anyway i won the bid and when i recieved it i put the charger in and it turned on by itself and was stuck ar htc screen i took the charger out and the phone went off, so i put the charger back in again and it didnt turn on this time, tookout battery and did reset and hard reset and still nothing? the phone doesnt have hardspl.
so i opened the phone up and look to see if anything was lose which it wasnt and i also manged to damage the volume flex cable and the bottom buttons flex!
so i left my phone overnight and in the morning i put the battery in and put it on charge and A RED LED LIGHT CAME ON!!!! which means it was charging so i thought if i press the reset button it come on, so i pressed the soft reset and nothing came on and the red light dissapeared and it doesnt come back again?
Can anybody help me whats wrong?
Since the previous owner has dropped the phone, anything could have went wrong.
First, check the battery pins on your phone, and make sure they are straight (not bent, not eve a little)
Hi I tryed that but it still don't work, also to follow up I put my htc in fridge for 5 mins and put in usb and orange light comes on so I left it for couple of hours and after it finished charging it virbrates and screen comes on but it just stays black so I took out battery and it didn't startup, so battery is fully charged and I. Put phone back in fridge and put usb back in and orange light came on again, so this time I pull out usb cable and the light is still on??? And I pull out battery and it goes off I don't know what's wrong???? Its driving me nuts!!!
Edit - ignore what I wrote above, okay I left phone in fridge and I put battery in and then I put in usb and orange led light comes on then the phone vibrates and the htc logo screen comes up but it is frozen there and I can't reset because I have no buttons because I broke the flex ribbon. I pull out battery and it turns off and it doesn't come back on so I put usb in and then battery and nothing but I can feel a tiny bit of vibration but not as strong as before. Its soo wierd the phone only powers when I leave it in fridge.
really need a solution fast
Please guys I really need a solution, don't leave me hanging. I was going to buy a new motherboard but I don't know whether its worth it because I font want to waste money.
I can't answer your question. But I know for fact that if the hd2 overheats monsterously the processor melts off it's spot or something and the phone starts to reboot at 25-30 Celsius degrees and that could explain cooling it down lets it boot. My suggestion is to sell the phone on Ebay as SLIGHTLY damaged Hahahah!
infact thats what i done i put it on ebay if anyone wants it let me, mint condition except boot failure I don't think it the processor because I can connect to usb and it comes as qualcomm data
The phone tries to turn on because I see the vibration motor turn once but nothing else happens?
facepalm.
....
Was there any need of facepalm makes you look like a retard. Don't do it please

Yet another thread about blinking red LED

Hi there,
a few days ago I bought a second hand nexus 4 from ebay. (had very good experience with my second hand N9 that I am using right now) The description said it wouldn't start after a android update. So I thought, no big deal, just flash a new OS and everything will be fine. But as it turns out it seems to be a hardware problem. Plugging in the charger results in a red blinking light. When I hold down -vol + power and then plug in the cable I get to the bootloader (or fastboot, not sure how its called) but neither "start" or recovery mode works. When I do the same with the usb cable attached to my pc (desktop, so should provide enough power) most of the time phone turns off half a second after reaching the bootloader. Only randomly it seems to work. I managed to unlock the bootloader and flash the default rom again (took me like a 100 tries) but it does not change anything. I charged the phone on the wall the whole night, still no change. I have seen some posts suggesting to open the phone and unplug the battery, but unfortunately I don't own such a tiny screw driver. Is there anything I can do? Or did I just spend 70€ on a completely broken phone? =/
nobody? really?
is there nothing left I can try?

Buy the tiny screwdriver. Better yet, buy one of those disassembly kits off eBay that has the T5 TORX, a small Phillips, and the plastic tools for prying things apart. They're only a few bucks (or quid, or whatever).
After opening the case and disconnecting and then connection the battery again the phone at least charges (white battery symbol while charging) and boots into android. But the upper part of the phone - I guess thats where the SoC is - get super hot really fast. At some point the phone resets, probably because of the heat. Is there something that can be done?

[q] totally bricked lg g2

IT ALL STARTED when my wife dropped phone and cracked the screen slightly and touch in some areas stopped worked.
Me being a technical person, went ahead and bought an lg g2 lcd+digitizer replacement off ebay and made sure it was OEM and had the LG logo on it. The phone is an ATT phone by the way and made sure it was for D800.
The part arrived and I went on my merrily way to replace it VERY CAREFULLY. The screen fit in perfectly and I reassembled everything carefully, connector by connector screw by screw.
When the time came to turn it on, it actually turned on and booted normally and the screen worked, the touch worked (altough some letters on the keyboard were douple/triple tapping,etc.) I ignored that and ran into a problem where when being on a call, the screen turns black as normal, but won't turn back on at all until a hard reboot is done. I went out and researched that this was the proximity sensor malfunctioning and that the replacement screens do not come with some sort of grommet that holds it close to the screen and blocks peripheral light. Well, I was annoyed, and went ahead and opened it again to see If I can remedy the proximity problem.
After some adjustments by the proximity and reassembling the phone, it booted up. I saw the LG logo, followed by the ATT startup chime and then, poof. All dark!! So what follows is a succession of fail after fail to try to get it back up and running:
-reopened phone, reseated connectors, nothing, same problem
-reopened phone, found that i hadn't routed the antenna wire correctly and that it had some metal part in between the wire that may need to be making contact with the metal on the frame. Still nothing, same problem.
-a bunch of hard resets, same problem.
-Try to go into restore mode, clicked yes on restore. Even worse after restore all I get to is the lg logo.
-As a last resort, went into download mode by plugging in USB to computer and phone, holding UP vol button. It went into 'download mode' and I went ahead and followed instructions on restoring the factory firmware flash. The process was 15 percent complete when it died, shut off.
-tried the flash process one more time and it went to 22 percent and died.
-knowing it's a hardware thing, I reopened phone and triple checked everything again. After reassembly, phone is TOTAL BRICK. No power, no LG logo, with usb charger and power outlet charger. No restore mode, no download mode, NOTHING NOTHING. Last known battery level was 13 percent when I was doing firmware flash attempt.
WHAT IN THE WORLD IS WRONG. Any experts know what I can check at all?
I managed to revive the power some how by disconnecting battery ribbon cable and holding power button to drain residual charge followed by reconnecting battery cable and plugging in charger.
I started the firmware flash and it failed at 8 percent because phone shut off. I swear to god..
nevermind. After the last post it wouldn't start again, disassembled, and basically found that the lcd ribbon cable connector pins were jammed beyond use. I'm pretty sure this wasn't the problem though in the first few times I opened it because screen worked fine. I disassembled more and found that the super glue I used totally burned into a small portion of the frame where the back of the lcd sits on as if it were some kind of acid or something. These may have been the culprits but I still think there was something else going on. If it hadn't been for that piece of **** proximity sensor this wouldn't have happen. The phone is a total loss and threw it in the trash. Done, RIP.

Thought you were going to say wife haha. Sorry to hear about your phone, just don't go giving your phone to your wife anymore . Thanks for sharing your sad story .

6p strange issue ,not sure if it is looped or not or if battery cable came off intern

Ok so i bought a second nexus 6p from ebay , it was advertised as a new sealed in box device
when i got it it was immediately obvious something was wrong ,the packaging was hard plastic not the embossed cardboard packaging with the "P" stamped in it.
There was some glue on the battery cover and when i weighed the phone it weighed less than my original 6p.
I immediately proceeded to start a return with ebay
but i used the phone for a bit and it seemed to be working ok so i was thinking of just keeping it and asking for a discount but then a few weeks later i was driving and the phone slipped out of my coat pocket and slid in between the drivers seat and the center console.
The phone only fell like all of 6 inches had a TPU case on it ,i was listening to music and it was connected to the radio via bluetooth at the time.
As soon as the phone fell the music stopped ,i picked it up from between the seat and saw that it was off , i tried several times to power it on but it was completely unresponsive no matter how long i held down the power button for , the phone was just charged to 75% before i got in the car and this happened bout 5 minutes into my drive.
When i got home i plugged the phone into the charger and i noticed that upon connecting it to power it immediately showed the google logo and started to boot , but then it goes into bootloop.
If i leave it plugged in it just keeps on looping , as soon as i unplug it it goes off, black screen and i can not get it to do anything.
I never press the power button when i plug it in to the charger and it starts to boot automatically.
I never see the battery charging icon screen at all when i plug it in.
I got refunded for the phone and didn't have to send the device back.
So i am wondering if i should take it to ifixit and have them replace the battery but i am not sure what is causing this issue.
Could it be that the internal battery cable came disconnected when the phone fell(all of 6 inches)
would an internally disconnected battery cable cause this behavior ,( that is my theory anyways since the phone does not loop or do anything at all when not plugged in and when it is plugged in i see no battery charging screen) .
I am guessing that they did a ****ty job refurbishing this phone and cheaped out and used a smaller battery(hence the lighter weight discrepancy) , not only in capacity but also in dimensions and that they did not glue it in good so that when the phone fell the battery slid and shifted inside the phone and came disconnected from the cable internally.
This is only my guess and i do not want to spend $100 to find out if it is correct or not and pay ifixit to change the battery only to find out the phone is bootlooped.
So i am hoping someone here has some insight and can confirm what is going on .
Maybe someone who has changed these batteries before and who has tried connecting the phone to USB while the battery was removed?

1+5 HardWARE Bricked? Soft bricked? Or neither?

Hello Devs, OP fans, lurkers alike
So I've had quite the quirky experience recently. Thought I had a brick in my hand for a while. Then strangeness.
Last week, I left my phone on top the car after gassing up. Half mile down the road, it slides off. My music from BT goes out. I return to find the screen smashed, display black and unresponsive.
Back inside the car, BT connects immediately and my song picks up right where it stopped. The capacitive hardware still works, vibrates when I tap or hold the BackHomeRecent, turns the "screen" off when I hold home.(or at least Android thinks its turning off).
So I decided to replace the screen and digitizer assembly with a new one. After transferring all the components as per a 50 step procedure found on ifixit, I go to power on. Nothing. No lights, motorcars, not a single luxury.
Maybe charging will help? AC USB yeilds nothing. But then my pc recognized it as USB Bulk 9008. At this point, I'm just about to give up and go buy another phone, figured its Bricked enough for me.
An hour later, my Android alarm clock for work goes off. Screen still black, but the led lit up. I had to pry it open and remove a screw to detach the battery connector to shut it up.
Obviously Android still works. Defective replacement screen, perhaps? Maybe I Fudded the reinstallation Elmer style? Is there hope to save my device?
PS. Dev Options were off during the accident, PC didn't even recognize anything while it had its cracked screen.
