blank/black screen after boot - frozen? gulp. . help

Howdy,
So I flashed my phone to cm4.2 last weekend and everything has been quite dandy. But I now I have a problem, and I kind of doubt its from the cmod because that was a week ago and this problem happened yesterday...
Yesterday I was talking on the phone until the battery died. Then I rushed to my charger and plugged it in. I tried to turn it back on but it would not. It goes to the G1 screen then to the CM boot animation screen then the screen turns BLACK! IT will not stop doing this. I have to keep pulling out the battery. Last night I even pulled out the SIM and battery for a few minutes. Then put them back and tried again. Same result. I charged it fully last night (while off) thinking that might help. This morning after the LED light was green I tried again to reboot the phone.. Also sometimes the phone will do this reboot sequence after I plug the charger in, but it still goes to the blank/black screen... awww..
I am really hoping I do not have to wipe the phone and start over again with my apps and stuff because I have not really found a great free backuper and have not backed up within the last few days. I can use home+end call button to get to the bootloader (right name?) screen. However I am REALLY hoping I do not have to wipe.
Any solutions? I tried searching but could not find an answer..
THANKS!! This is basically terrible timing too because I leave on vacation tomorrow morning and will be needing 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.

[Q] Incredible S Won't turn on at all anymore.

Got the phone just over a year ago so it's just out of warranty.
The phone recently started turning off, forcing me to remove the battery in order to restart it. This occurred when I turned the screen off (power button) and left it off for more than about 20 seconds. This was obviously a massive pain in the ass, so I decided to s-off, root, then put custom firmware on it.
So I plugged it into the computer and was just downloading all the required bits, and I got a phone call. I picked up, talked for a bit, then when I hung up I instinctively turned the phone screen off. I then left it for about half an hour until the downloads were done (HTC Sync downloading at 40 kbps >.<) and then went to turn it back on. Of course it had offed itself.
So I went to pull the battery out and do the usual -- to no avail. I tried outing the battery, plugging it in, then putting the battery back in (as read from a random Google result) and nothing.
TL;DR:
Here's the status:
Phone began doing the seemingly standard random turn-offs that require a battery loop.
After a week or so of this, the phone stopped coming back on.
And it will not give any sign of life (No vibrates, no lights when plugged in, no PC response)
Phone has never been dropped / watered
Tried different leads / USB - power adapters
Battery was at about 80-90% at the time of offing forever.
Tried with SIM Card in and out
Tried with MicroSD card in and out
Is this **** bricked? I wanted to wait for the Edge to come out before I upgraded; I don't want to end up with a Sensation or something.
Any fixes?

Sounds like your phone just died.
Another explanation is you have something loose, you should open it and check .

I'll take it in the an Optus shop today and start yelling abuse, maybe that will get it fixed. Worked on my old Legend. If that doesn't work, I'll open it up and have a look.

Yelling didn't work, they just tried out the phone on all their chargers and it failed.
So I'll open it now.

OK here's a picture of the USB charger bit. I can't post external links, so I'll attach it.
It looks okay... is this what I should try replacing? The USB thingy?
BTW, I unplugged everything then plugged it all back in, so nothing's loose.

Hey Andrew, I sent you a PM.

Struggling with the same problem...
Just made a call from my phone. After the call the phone seemed to be stuck on the call screen. I didn't think anything of it and left the phone alone. When i tried to use the phone again, there was no screen and the phone was not responding. I tried to re-start the phone by pulling out the battery but it won't switch on. You people seem to have the same problem. Any help would be really appreciated. Thanks.

Just a suggestion, but have you tried removing the battery and powering on with the charger connected?
I guess this would help resolve whether it's a battery/charger issue.

I/O 2012 N7 now hard shutting down (crashing)

I got my Nexus 7 at I/O this year and I've been happily using it for nearly a month now. I don't know if my device differs in any way from one you can get form google play other than the white back.
Last night I was plugged into my wall charger at around 14% battery and playing SongPop with my girlfriend when my screen just shut off. It was like when you hold the power button on a laptop and BOOM, everything is black. It wouldn't turn back on so I unplugged it and plugged it back in. Got a charging screen so I let it set for a bit.
I came back maybe 15 minutes later and I was at 9% battery, which was odd given I plugged into the wall at 14%. I played with the phone for maybe 30s after boot and it happened again, I saw some weird artifacts on the black screen as it quickly shut off and the speakers played an awful crackly screeching noise. Plugged it in again, came back a bit later, still at 9% and played with the device again, same issue only after a little more time.
I'm currently at work with my N7 plugged into my Galaxy Tab 10.1 charger and charging it from 0 to 16% currently. The device is on but I haven't been touching it (and I don't plan to until it's at 100%).
Has anyone else had this issue?
I cant tell if it's some way I'm touching the device that's causing it to shut down hard, some issue with the battery or charging that is causing a rapid battery drop or even a short in the way I'm holding it when it's plugged into the charger?
I don't really want to deal with ASUS warranty returns already, though I have been unable to find anyone else with the same issue through google, so I turn to you for advice and similar stories.

Mine did the same thing the second day I had it. Now it won't boot. I'm waiting for Google to send me a new one.

Mine did something similar last night. It was at about 6% battery charge and all of a sudden the screen just went black. I went and plugged it in, but it wouldn't power on completely (the screen was on but there was nothing there). I started seeing really thin, small green lines running down the screen. I turned it off and on a couple of times, and finally it booted up. I left it plugged in for awhile, and I just took it out at work to use a bit and everything seems perfectly fine. I wonder if there are some firmware issues with the power management or something. I was all set to put in a return with Google, but it appears to be okay. I'll keep a close eye on it for the next couple of days (I've only had it for a week).

After leaving mine off and charging at work to 100% it seems to be working fine. I used it all last night with no issues. I haven't tried wiggling around the usb cable yet in the port to see if that caused any issues.
Firmware issues sounds about right, some sort of low battery safety feature or something? Who knows. I'll update this thread if I continue to experience problems. I'm already past my ability to return to Google so I'm in no rush to warranty to Asus and lose a development tablet.

[Q] Xperia T 2nd phone, Dead

Hey all had my first phone about 9 months. It would not charge once, and eventually went to 0% and was fully dead. At first it got replaced with a new battery. I then went to hand the phone in once again! a month after... the battery was lasting half the day where as before it would just last me the whole day.
They sent me out a new handset (after i threatened them with the law (i have no insurance- however the phone is not lost, damaged or stolen)).
Now iv not noticed any problems with the handset.. I recently upgraded to the new firmware uk generic.. The phone went to 0% for the first time ever. I try to charge it and it does not charge. I have left the phone plugged in with the power button stuck down for an hour. And now what happens is, the phone boots to the load screen and just as the interface loads up it says Power off shutting down. And then keeps turning off and on off and on.. The phone will still not charge when turned off, but i cant get the phone to load up and start charging ?
Any help appreciated iv started to have enough of Sony these past two years
Thank you
Warwick

After continuously trying to boot the phone. It eventually goes dead again. I can charge the battery a little bit by holding the power button down. But then the light turns green thinking it must have enough charge to boot (but hasnt)
Is there a way to keep the force charging on for longer rather then it rebooting itself forever?

Keep the power button pressed with a rubber band while it's connected to the charger. Leave it for a couple of hours.

Why will the rubber help catalyse the battery?

For some reason keeping the button pressed will allow the phone to charge. If you don't believe me Google it. I did, tried it, worked for me and was able to flash another FTF... not a big deal.

I think you misread my first post mate lol I was joking about the rubber
I'd already stuck the power button down. It's sorted now though but thanks for the post
