[Q] Hd2 having seizures!!!

Hello,
I've had my hd2 for about 6 months now and about a month ago it started randomly crashing. I'd have to take the battery out and reset, but when i'd start about 1 out of ever 4 times it would show the inital launch screen, but the numbers in the bottom left would never come. So i'd have to remove the battery again and reboot.
Then it started happening more frequently. Random restarts, crashes, and the phone didnt like to boot at all most of the time.
Last night, it gets really bad and i am able to get into the phone once. After that it freezes always when you initially power on, you see the boot splash, but no numbers in the bottom left, no moving forward.
AND NOW when i power on, the screen stays black, and it just vibrates and will not stop at all unless i remove battery. In fact, as soon as i pop the battery in, it starts doing this.
WTF!!!!!!!!!!!!!!!!!!!!!!!!!!!!

anybody

Try doing a HARD RESET.
If that does not help it means you have a damaged HD2 motherboard, try contacting T-Mobile or HTC for a replacement.
I'm 100% sure it is a heat problem. I do have the same problem. With my HD2 disassembled I checked that "freezing" the motherboard make my phone boot without a problem... and it worked properly as long as it stayed cool.
I'm trying to replace the motherboard by myself as I do not live within the USA...
Hope it helps.

Same exact problem here, although it happens less often for me. How do we keep the motherboard "cool" so it won't happen? or is this a sign of motherboard going bad soon and it'll be replaced sooner or later??

I think it is a sign of a dying phone... or at least a dying motherboard.
Maybe (just a theory) these are signs of a "cold joint" similar to what happens to the Xbox 360... and the way to fix it is to "reflow" the motherboard... but we need a more technical point of view on this one...

Thanks for the replies. I have tried the hard reset, but it just vibrates with the screen off still, no success in any attempts to do anything. I guess i will have to contact htc since i did not purchase the phone from tmobile.
I did notice before this happened that the phone was getting hot after even a few minutes of use. So i have to assume it is a damaged motherboard or whatever it is inside of my precious hd2 that makes it bring me joy.
Now i am joyless and sad.
Back to the old 2g iphone
*cries*

If i press inside the red area (including home button) it wont work and its just like i pressed the near side, like icons in the left or right of that red area.
I tried full data wipe, cache and dalvik, tried flashing newer sbf and no good.
Do you guys have any idea on it?
Thanks

Bad news bro.
I'm pretty sure its a hardware problem, the screen must be damaged...

So i need to replace it?

Better to get a new phone =D

a new phone is your option coz replacing the screen would cost you alot while you can get a better phone in a few bucks more!

New screens are available on amazon for 12 pounds (at least I spend this much)
However It may be a signal cable. They starts from 30$ on ebay

There are disassembly videos on Youtube.
I had a similar problem and I did the replacement two months ago and it works.
I bought the screen digitizer with tools on eBay.
Be sure That you have a torx3 beca use it didn't came on the tools! ;P

I had the same problem... I sent to the Moto Assistance and the had to change the touchscreen for a now one.
Good luck!

Not the cable. If the cable was damaged, it would shut down the entire screen. It's a problem with the digitizer. Hopefully for you it's relatively easy to exchange it, but you'll damage the camera sticker, the top panel of back side, above the battery and the speaker grid sticker (all of those are glued to the phone) in order to open it. Doesn't matter the way you take them over, you'll always damage it. Might wanna buy some of these on ebay too, although I'm not sure they sell it.
I had the exact same problem with my first M2, it was still under warranty but Moto took sweet 15 days to exchange it, and they returned my phone with a stuck volume rocker. Had to send it again, they took more than 15 days this time, so I asked for a replacement.

PiPo M9 drop dead =<

Hey!
I had a PiPo M9 (WiFi) now for about 2-3 weeks and everything worked perfectly.
No problems with rooting and installing ROMS ( i fixed that 2-3 days after i bought it)
I was playing some angry birds yesterday, and all of sudden i had VERY low battery, i put it on charge even if i recently took it from it.
Then i noticed that the DC-connection in my tablet is "loose" , i needed to have the cable in a specific position for make it charge.
Battery was fully charged but it said i had about 16 minutes left, and in 1 minute it dropped to 43% and only had 2 minutes of the battery left...
I tried to calibrate the battery after it was fully charged (i let it charge for almost 10 hours) but there was no difference...
Anyways... i played some games later on and forgot about the position of the cable so the tablet died...It had a bootloop about 6 times and i was trying to put the cable correct for make it charge but i failed and the tablet died.
Now it doesnt react at all, and unfortunally i don't know what the EXACTLY position is for the cable so i have been trying around but without success...
When i am connecting the USB to the computer it doens't react either, and i tried to push in RESET while holding the other buttoms as well, without success...
I Don't know what to do , and i don't know what is wrong?
I opened up my tablet carefully to see if i could see the problem but it is hard to do anything without knowledge about it....
I know that it has something to do with the DC-connection but i can also imagine that it has something to do with the batteries..
If i need to change the batteries , what should i buy? And how should i do? I need a guide, walkthrough ,... i have been googling around , also on youtube, without any luck...
Anyone out there who can help me?
I am kinda desperate.. :/

I solded and fixed the DC-contact, it was loose, but there is a component missing and i am unsure what component it is, so i have a picture and hope someone can help me out....
I'm a little unsure of what component that is missing, but it is backside off the mainboard, just below the dc connection.

Should I try to save my black screen nexus 4?

Hello people.
I need help to decide if I should try to save my nexus 4 or not. It has been dismantled for the past half a year and i recently got it to show signs of life after battling the steady red ring of death. (Was simple by the way, just used a wireless charger for a couple of minutes) But if I turn it on, it vibrates, the screen lights up and that is just about it. So i have no idea if the phone itself is functional. Some of you might tell me not to bother with such an old phone, hell, they aren't even sold anymore. But this phone has stuck by me through thick and thin, and has a sentimental value. I nearly jumped of joy when it showed signs of life after such a long time. I am not a rich man, so i need to manage my finances. Screen replacement would cost me 25 pounds, back housing would be another 10, but what if the phone is still not functional? Is there any way I can find out if I should take the gamble?
Some info -
I am not entirely sure if there is an OS currently installed on the device, as I was experimenting quite a bit before the battery run its coure.
I am also missing one of the connector things that are circled (there is one and a broken spot where another one should be) but i have no idea what it connects to. The little peg itself is safe and sound in my possession, if it can be welded back. It connects to whatever is under the power button on the back housing.

The screen is cracked in three places, but was working the last time I remember. But there have been many (and I mean many) dis and re assemblies since then.
I probably love this phone more than my friends and family. Just want my favourite piece of tech to be my companion again.

Could the red light be due to a dead battery?

Thankls for the reply. The battery is new and the red light issue is sorted. The phone just doesnt do much more other than vibrate and light up the screen. How do i know if it is still worth investing money in is the real question.

Axon 7 Repair

I dropped my Axon 7. Though there's no visible damage, the phone will frequently freeze (not turn off) and just continue to display whatever was on the screen at the time. Or the the charging LED will remain on if it was just charging and not actually booted, even if I unplug the phone.
I opened it up and reconnected all the cables, but no luck.
Once it starts, if left gently on a table it will continue to run, but if I jostle it it will likely freeze.
I've been experimenting and know I get the same behavior if the phone is running on AC with the battery disconnected (I think that worked...) , or if I run unplugged with the battery.
Any ideas? Since I already have the phone open and don't much have to loose, I'm willing to attempt more surgery, but I'm not sure how to diagnose the fault. (Yes, past the 2 year damage warranty).
Happy for your thoughts and suggestions!

There was a post on here with the exact same scenario, if I remember correctly it was a cable to the screen/display.
I've dropped phones and sometimes the pins bend slightly so check the connection pins.
I even repaired one that fell into a bowl of milk

found something?

Ok - What do you think about this? I can't tell if this is superficial. ($20 USB microscope I bought for my kids rocks)

Assuming this is the issue, does replacing this cable mean removing the screen? I've heard that's hard...

I can't see from the pic properly but it is possible, the only way to know for sure is to compare with an original condition unit. (Looks better than some I've seen)
I was fortunate enough to have the same phone as a backup so I could check in my case.
Just make sure all connectors are snapped into place and no broken fragments in the connection.
I hope you get it sorted

That's in the outermost part, it will surely not cause anything at all...

I was afraid of that. Back to the drawing board... or just wait for good Black Friday deals.
