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] Is my Nexus 7 dead? Please give me options to charge/turn on

Good evening everyone, I have a Nexus 7 8gb, but the thing is, I cannot turn it on now.
It happened as follows:
I was using it every now and then, mostly to read and play.
I was using the charger to charge my cellphone too (XTC Explorer) as it was a lot faster, being 2amp/h.
I updated the cell to 4.1 and at the same week noted the battery wasn't running that long, but blamed it to the rom.
The cellphone also took a lot longer to charge with the nexus charger, yet again I blamed the rom.
I noticed the Nex was at 8% while reading so decided to charge it, but I guess I forgotten.
The next time I wanted to use it it wouldn't turn on. I figure it had no battery.
I plugged the nexus charger to the nexus a whole night and in the morning it still wouldn't turn on.
I figured something must be wrong with the charger, so I tried with the cellphone and nook color charger, but both are .5 amps/hour.
It wouldn't charge, neither connected to the pc (also .5a/h via usb) so I tried a psp go charger, as it is rated at 1.5 amp/hour, much closer.
I connected it at night and saw the charging icon (white on black battery with the ray) and left it overnight.
The next morning it wouldn't turn on either.
I've bought it almost two months ago and I really enjoy it =) but now I'm desperate.
I cannot call google play for the warrant because I'm in Argentina, and I don't believe they will ship me a replacement, nor anything. This one my brother bought from them, but he went back to US a few days ago, and I didn't think of giving it to him to RMA.
I tried keeping the on button, for 5 secs, 30 sec, 90 secs, 120 secs, and no dice. Also tried holding the Up Volume key to restart it, but no chance.
Please help!

Had a similar issue to this over the weekend after not charging for 2 days and the battery going dead. I let it sit on the original charger overnight and for some reason it did not charge. It kept booting and shutting down once it booted due to a low battery warning. It eventually got to the point where the screen would go to fuzzy lines and light but no boot.
To finally get it working I did a combination of a few things but don't actually know what got it going.
Put it on a different (kindle) charger and let it sit for an hour or 2, did several hard resets holding both just the power and also the up/down volume and power all at the same time for up to 60 plus seconds. I switched back to the stock charger and did an additional hard boot by holding just the power for 30+ seconds and it started booting and charging.
I did however put it on the charge again last night and noticed this morning it was still at half battery and didn't get a charge. I ended up putting it on a mifi charger this morning and it's charging again so don't know what is up with the stock charger. Also, have all the latest updates to 4.2 as far as I know as there have been charging issues reported with earlier versions...

Try this, it just saved my device:

try holding down the volume DOWN and the power key for 10 seconds, then release the power key and keep the volume down key pressed, and it will force the unit to restart into the bootloader from any stage, its effectively like pushing the restart button on the front of a computer and constantly pressing the delete key to get into the bios.

Rebooting and powering off

The first problem I have read about. My Fire shuts down when plugged in, and it will not start without unplugging it. It is charging though.
The second I haven't. It will reboot unless there is some sort of wakelock. So, to keep it idle without it rebooting, I have to set a partial wakelock. This is causing the battery to drain very fast.
This all began after plugging it into a new charger (Duracell brand). It exhibits this problem with every charger. Does this mean the charger shorted something?

Well, good news is I found this thread with the same problem mine just started having. Bad news is I see the date is almost exactly three years ago and no further posts. Does that mean I should assume it is a hardware problem, and time to move on? So disappointed, my 2015 KF died 2 weeks ago due to internal storage chip malfunction. Now this one dies within weeks of each other?
I've just been powering my 7" HD completely off when not using it. It stays on fine when watching or reading with it, but after pressing the power button to put it to sleep, it seems to reboot. Then, after rebooting and hitting the homescreen, it will again timeout and go to sleep, and reboot again. Repeat until battery eventually dies, or I intercept it and shut it down completely. Also noticed it won't power on while charging now. Dagnabbit.

Weird Battery issues

So my turbo just turned 2. For the past 6 months or so been having some weird issue. I was on RR Remix for a while, then went to CM14 by BBH27 for a while, and then back to RR, and now on ComputerFreak Stock. I don't have any issue with charging the phone. Quick charge works just fine.
I have had issues where the battery will just be dead even if it was at like 50% and confirmed charging.
I thought maybe it was my stupid charger (I have another that I have yet to test) but then last night, after charging my phone before I went to bed i unplugged it. I woke up around 6:45 to find my phone once again dead. It looks like around 2 am the battery just fell. Dead. Just gone. I go and hit the power button and i got 1%. The battery graph looks as if i turned the phone off. For the most part my battery last all day 12+ hours with some good usage too.
I'm getting ready to flash back to stock now that full stock MM is out now to flash and see if that makes any difference.

For what it's worth, my Turbo would just straight up shutdown when I was on RR. And not go through the shutdown process, just crash to a powered off state. It would happen if the battery was full, low, or anywhere in between. I don't know if that's the issue you were experiencing, but I suppose it's possible.

My daughters is having the same issue.
Anyone have a solution?
I've tried clearing caches, battery recalibration, etc.
Going to see about doing a fully clean install tomorrow if she is okay with it.

When this happens and the phone just shuts down, does the battery percentage immediately jump back up when you plug in a charging cable? I was having that problem when using wireless charging a lot. It turned out be a battery calibration issue. You can re-calibrate by holding the power button and KEEP holding it when the "Power Off" dialog pops up. The phone will eventually reboot itself then leave it overnight on the factory turbo-charger.
One warning - Since the marshmallow update, performing this procedure seems to wipeout your BT connections.

Run a Nook HD+ without a battery.

I bought my Nook HD+ in 2013 and it has been a great companion all along. About two years ago, I noticed that the battery was not what it used to be, requiring charging too often. Last year, I installed LineageOS on the Nook.
About three months ago, something happened to the battery so that the Nook would turn on and be usable only if the main power was connected. If I switched off the charger, the Nook would immediately shut down - and by shut down I mean it would just blink off, not shut down over a few seconds. Also, in the shut off mode, it would lose battery a lot, like 20 to 30 percent in a day, without any usage.
Then, about a month back, I forgot to charge it for three straight days and now it won't turn on at all. When I connect the charger, the charging light turns from green to red, and stays there, indicating the battery is charging, and the back of the Nook also becomes hot, but whatever I do, it doesn't turn on. When I press the power button, the screen comes on and shows the charging icon for a second or two and then goes off. I've left it charging for a couple of hours, maybe six or eight or so, but it still won't turn on.
If I remove the battery and turn on the main power, the charging light keeps blinking green and red over and over. So, is there any way to use the Nook without the battery, running it off the mains power only? And if there isn't, is there any way to turn it back on? I've already gone through the threads here and tried some of the things but nothing has worked. I don't have a higher power wall charger, and it is not possible to go out in the present condition, what with the lockdown and all.
Please help.

Hi
I also have a Nook HD+ that I'm still playing with

I also installed lineage on mine a year or two back, but I've had random issues with mine. I'm going to try to reset and reinstall it in the near future (like, maybe this weekend or next).

I know that, if the tablet runs dead, you _have_ to put it on the original Nook wall charger and let it sit overnight... mine just went dead a couple of days ago and I tried just plugging the cable into a generic USB charger, but it didn't charge. I then remembered this and plugged it into the Nook charger and it charged overnight.
If I remove the battery and turn on the main power, the charging light keeps blinking green and red over and over. So, is there any way to use the Nook without the battery, running it off the mains power only? And if there isn't, is there any way to turn it back on?

I have no idea about this part... I've never taken mine apart (I wanted to buy a replacement battery a few years ago but they ran out and I never found more). Update: I just searched and there are a few battery replacements listed with Google search, I just don't want to pay 40.00 to 50.00 when I can buy a new tablet for a little more than that.
I usually just leave mine plugged into my bedside clock and it keeps charged, or if I unplug it plug it back in within a couple of hours.
Hope you find an answer.

better off buying a new tab
