MY HTC diamond does not switch on neither does it charge.....please help :(

Hi, I have been using my HTC diamond toch for nearly 2 1/2 months. a few days ago, i did a rom update using Dutty's rom update. All went fine duing the update. used the phone for about 5 days nonstop, no issues at all.
But yesterday all of a sudden the phone has swtiched off by itself, now it doesn't switch on. Thought the battery might be dead so i tried charging but the enter buttton area doesnt glow and there is no sign of charging.
I switched batteries with a friend to see whether it was faulty but it is in good condition.
What do u think the issue will be ?
Thanks
Buddhi.

I have the same problem. I've just got my phone back from being repaired as the touch screen got all messed up and now it won't charge. I plug it in and the touch pad does the charge animation twice then stops. It'll randomly try to turn on but it doesn't even get to the point where the red writing apears before it turns off again.
Help?!

same problem here

Dudes.... Chill!!!!
Here's what you can all try ....
First you guys need to know that de HTC does not charge if the rom is inconplete/damaged .
And.....
If your batery is realy dead there is no initial power on the internal battery to manage the chargement.
So ... resolution.
Fist way .
If you know any one that may have an other HTC Diamond you need to swamp batteries so the good Diamond that has the internal bat ok and charge it there.
Second way . this one i did it my self .
Go to a Local ChinaMan store and buy a multimeter and a regular Universal Adapter.
Heres how it hoes ...
Use the Multimeter do figure out the polarity pin's on the battery ex: + and - .
remove / cut one of the plug's from the Universal transformer and also tag the polarity.
set the voltage to be close to 5 V - 1 Amp .
Can be 4,5v or 5.5v no sweat
Conect the cuted wire from the Univ. Adapter to the Diamond Battery respecting the polarity.
Leave it for a wile..... ( Probably up to 1 hour but chec from time to time tme battery temperature and if possible a reading on the bat voltage levels.)
Done!
Put the battery bat and boot your diamond or turn on to boot loader.
**** Attention if you don't have more than 50% of the bat charge compleated you wont be able to flash your phone****
Any questions Just reply back.

same problem...
its just...my battery was full before the upgrading...i was Unlocking my Diamond..and the upgrade didnt move more than 0% just when i looked on my mobile...there was black screnn...pluged it out..tried to power on..nothing..tried to charge...nothing again..i tried hard reset(vol down+power+back+reset)..it just wont turn on..please help me..im in panic

Help, I have the same problem and my battery was fully charged before this happened. Voltage reading is 4.2V on the battery.
I also tested the power button and there is nothing wrong with it, it conducts when pushed.
Usually pluging in the charger should start it up, but it will not start.
Anyone have any solutions?

I couldn't fix mine so phones 4 u replaced it with a touch hd

I had the same exact problem two days ago.The phone was not charging while it was on,and when it was off it did that charging light animation twice and then third time the litght managed to get in the middle of the button and sudennly stopped. So here is my solution . I'v managed to charge the battery on another phone and turned my Diamond back on. While still attached to charger and power source i'v performed a soft reset (by pressing the reset button beneath the stilus) ...the phone reseted and now it's all ok.

I had same problem , no solution yet.
When I had a Mpx220 I had fixed changing a fuse, but I can´t see nothing in internet guides or foruns.
If someone knows how to repair tell us, becouse htc service in our country isn´t good and my device is outdate warranty.
Regards,
Gus

Someone has fixed?

I have the same problem but on my samsung corby GT-i5500. I installed the clockworkmod on my mobile by rom manager and rebooted in recovery, I think i've installed a wrong version and now it does not turn on at all! what should I do? my parents will kill me if they discover that ive broke my phone

I cant turn on my phone. Help please.

I have this installed [ROM] CyanogenMod-6.1.0-RC1 for Hero CDMA
I was running wifi tethering and installing a game called chess.
I heard my phone vibrate quickly and the screen was black. I tried to turn it back on. But nothing. So I removed the battery and waited a couple minutes. I cant get it to come on.
So I plugged it into a charger and the red/orange LED is on as if it is charging.
The phone will not even attempt to start up
Any ideas?

Phone just seems dead to me... probably just needs to charge for an hour or so

If it's not charge up and running by now, you'll need a new battery.

Thanksgiving day I had my phone on but was doing things around the house and when I went to check my phone it wouldn't wake. Holding down the power button, nothing, it was dead. I know the battery wasn't drained. So I plugged it into my USB and the light didn't turn on either. I sat staring at the phone for a few seconds to troubleshoot and it suddenly began to boot up and after everything loaded I could confirm it was half charged.
I'm running the same version of Cyanogen as you. Are you using the original battery or 3rd party? Mine is 3rd party.
Have you had other strange occurrences leading up to this? Twice in a week I woke up to find my phone on even though I know I shut it down the night before and not accidentally rebooted.
Since I was able to get my phone to boot back from temporary dead the phone has frozen twice while texting. I didn't battery pull or anything, it just rebooted by itself after a few minutes. I plan on switching back to my old battery to see what happens.

CM9 My Optimus wont turn on

Hello Pleashe help!
I have installed cm9, and for the night plug it in the charger, and now it wont turn on! It's plugged to the charger but nothing is working! Please Help! I cant turn it on! SO many thanks to helpers! Please guys!
I'll be so glad if you help me!

Have you tried a battery pull and then turned it on again? It could be a BSOD.

had the same problem (sort of) yesterday without the powercable connected, it seemed like the battery was empty while it shouldn't be, i fixed it using power+ vol up but i guess a battery pull should work aswell
sent from my LG 2X using cm9

Well i have tried for 5-10 mins to fix it, plugging it on the charger, and pulling the battery, this morning, but i can't get anything. What can be that for?
Can i revert back to stock (nVflash), or even turn it on? MUCH much thanks to everyone!
I really want to get my phone working, If someone can help me, i can give him some money in PayPal!
P.S I'm in school now, and with another phone! When I go back home i'll try what you say again! I left it in charge (from pc) and hopefully, it's because battery has drained or something! Thank you for the replies! I look forward to reply's, about how to solve this. Thanks!

had same problem this morning (left phone in charger for night).... i just disconnected phone from charger, removed battery for 10 sec, put it back - and phone is on...
only problem is that battery level was showing 999% (unknown), and after ~10-20 minutes it was 1% all the time (worked with 1% 2+ hours).. now it is charging again.. everything seems ok.
**
If it wont turn on, just remove battery, and connect it to PC while holding volume up key (or down.)... it should boot "upgrading firmware" mode... after just use smartflash and restore to stock.

hm... happend second time, when phone was on "wall" charger..
when charging from PC - no problems... when from "wall" charger - always BSOD after few hours...
anyone else have similiar problems?

I had the same as in OP during first night while it was hanging off the wall charger. It hasn't happened since, but I enabled "keep screen awake during chargin". I beleive I read somewhere here it should help with that.

Same problem here overnight charge and the phone wash dead.
After a battery pull it was ok.
It 's a bugg.

Mine survived overnight charging just fine...
And it rocks (ICS i mean).

Solution for Me
Hey i got my optimus 2x just yesterday on Starhub Singapore, and similarly, i HAD the same problem until i followed some post above about removing the battery, plug in the computer/laptop with proprietary usb cables, WHILST HOLDING THE VOLUME UP AND POWER BUTTON TOGETHER. Hold for 10 seconds at least
Nothing happened. So i didnt get the flashing menu or mode on screen
Then i put unplugged the phone, put the battery back in, and tried again, suprisingly the LG Logo came up, but now it hung there.
Removing the battery...
EDIT: I removed the battery, now working good. Hopefully this dumb sH*t wont happen again. Beautiful phone. Hope this solved everything
If not, try doing a hardreset maybe? Hold power + Volume Down Key BUT ONLY IF YOUVE TRIED THE ABOVE METHOD A FEW TIMES. cause all your data will be gone POOF

Xperia T bricked? Does not respond to anything. HELP!!!

Hello!
I have a little problem! unlocked bootloader Xperia T
I installed the latest kernel pac pac rom and it was also set it all went well you just have wifi, sync, ring tones, etc. analyzer cleared the apps they are using and leaving more than half an hour, picking any trouble but I did not see no warming is not broken! I got my pockets all finished the battery was around a 77%!
After about 45 minutes I pulled up I want to fix anything I want to turn into nothing, then restart the combinations were tried but did not respond but no charger, no machine can recognize there is no mode!
Now I do not know that the battery is sucked bone or something came out of the motherboard?
Through charger but no change was up all night!
But the biggest problem that does not respond to anything either! The LED does not light up anything to do with it!
So there is no warranty on it so I do not know what to do?
Sorry for bad my English!
I hope you can say something that will help you just as it will be 3 months old.

Do not worry.it happend to my brothers Ion too.it didnt recognise USB or charger.but after seven hours left on charger the led turned on and phone charged.then it powered on.

[Q] My XperiaZ took a shower :D

So ...Friday night i got drunk and stayed in the shower for about 3 hours WITH my phone and car keys in my pocket.
when i started to sober up i tried to turn on the phone but nothing happened. First i thought the battery discharged and tried to charge it ...ok ...the led was working ..after a while i tried to turn on the phone again ... it worked ...but the screen flashed few times, the led was doing the same (like there was an imperfect contact) and the touch wasn't working either. Couple minutes later my phone powered off alone and the charging animation appeared ... no flashes , it seemed to be fine in charging mode aand the battery was 61% (so it wasn't discharged) ... tried few more times to power it on and gave up . I left it in my car in the sun until i got home.
I managed to disassembly my phone .. wiped any visible drops and put it in rice until 1PM today (more than 12 hours)
Today i put it back together. First try to power on -- didn't work ... i plugged in the charger and after few minutes the charging animation appeared, same battery status. I tried to power it on with the charger plugged in and it worked , when it was supposed to ask me for my PIN something flashed... i guess the notification led .. and the screen turned off.
After all this i tried a few more times to power it on ... but nothing. The only thing that appeared was the charging animation.
BUT the last time i plugged in the charger the notification LED turned RED (IT WAS NOT FLASHING). I pressed the power button and the LED turned off and that's it .... nothing since then.
I noticed that if i remove the battery and plug in the charger the LED turns ORANGE (i guess ).
I guess it's pretty bad...
Is there anything i can do ? Can it be fixed? What is the problem now ..?(fried battery maybe ?)

Sony Care in my country (Romania) seems to be a pain in the ass ..
My phone is bought from USA and i have wordlwide warranty ... I called sony some time ago and they told they can't give me warranty here in ROmania, they did not say why even more that lady even refused to tell me if there is any authorized/partner service in my city.
Anyway ...regarding the issue in this post .. I took my phone to a service ..they treated(cleaned or whatever) for water and oxide and it works fine now. No parts were damaged. It cost me like 20€.
