I just did a factory data reset yesterday and I was calibrating the battery for the new ROM. When I let the phone die all the way, I left it unplugged for a little while because I was in the middle of a movie. When I got around to plugging it back in, I am getting a flashing LED, no charge indicator, and it won't boot up. Every once in a while, the HTC boot logo will pop up and my phone will vibrate like it's turning on, then it will just go back to the flashing LED. I can get it to jig into fastboot ever so often, but when I try to boot into recovery from there, it just turns off and goes back to the flashing LED. Everything I have read says to hook it up to my computer and use ADB to reboot it, but when I bring up the command prompt, it says that ADB isn't a recognizable action or something like that. My laptop also doesn't recognize my device as being plugged in. I've perused the forums on here and to no avail so here I am asking for help... HELP!?

Okay, here is the problem. I have looked around, and this thread seems to be close to what I initially ran into.
http://forum.xda-developers.com/showthread.php?t=2199042
What seemed to cause this was some sort of update verizon was telling me to download, and I kept deferring it until I accidently hit yes. After hitting yes and the update going through, the phone booted to "System software not authorized by Verizon Wireless has been found on your phone.”, which would force me to restart.
If I used odin's button patterns, I would come across the mentioned route in the thread.
But the route I went (because I assumed it would work) is download what was prompted as a "custom os" as opposed to denying it and (I'm assumed based off the thread just posted) starting the phone up. After an hour long car ride, leaving the phone alone and apparently "downloading" the custom os, my phone turned off.
Now what I am facing is only a red led when charging (which is normal when charging while off), but when using any odin button pattern, my phone simply vibrates and nothing more. Nothing on the screen, even when pressing the power button itself. It just stays pitch black. I have no clue what has happened. Any possible suggestions? I tried with battery out, charger in as well as battery in, charger out, and charger in, battery in.
If you plug the phone into your computer and power it on/attempt to enter Odin, does your PC recognize it?

Actually, plugging it into my computer just keeps making it vibrate as if it is starting to power on. I can't even get into odin or even a screen coming up for that matter.
Hey thanks for the help! I figured it out. I guess the battery was incredibly depleted from leaving it in download mode in odin. I charged it up and after a few hours, the power came on. I followed the guide in the thread I posted and it worked like a charm. Sorry about the confusion and I greatly appreciate the help. Thank you!
what am I supposed to do in this instance?

Ok when I leave it there to charge after about 5 minutes it tries to boot up again on its own... its like a boot loop but it stays turned off for about 5 mins in between.
Now I believe its officially stuck at the CM logo screen after the data only back up and restore. It stopped turning off which I think was due to battery and when I plugged it into the PC it turned on and has been at the CM logo screen for about an hour now.
It also refuses to boot into recovery now. Stock or Open Recovery. It only shows the green charging LED and when I do a force shut down it blinks on and back on in about 1 second. I have no clue what the deal is. I'm going to try and flash a stock image with RSD Lite and try it all again.

Your battery is empty. You can't flash anything via fastboot in such state.
When the battery is empty while starting the phone, the bootloader charges it a bit first (that green LED). Only when the battery is charged a little, it switches to boot.
What you want to do is to catch the moment when it starts to boot and hold the volume-up to get to OpenRecovery. OR supports charging so you can let the battery charge more there.

Thank you again for your responses.
I was thinking along those lines... But it seems like as soon as it gets a charge that it goes right into the boot logo. There doesn't seem to be any middle ground to go to any recovery mode. I was stuck in a similar situation before but it wasn't constantly trying to boot.
Here is what happened:
When I flashed data only, I selected "reboot after" option so it is constantly trying to do that re-boot but since it cant boot it stays at the CM logo I guess until the phone dies. Then it charges for a while with the green LED and then it tries to boot again. I have tried to access all kinds of recovery and fastboot and everything at the usual intervals and I cant get it to start any recovery mode because it is still following the re-boot command from Open Recovery.
I will keep trying but this time seems different than when I had low battery/no recovery in the past instances. Something is overriding my recovery and I think it has to do with the Open Recovery reboot after flashing command.... I even opened up the back of the phone and disconnected the battery and its still not working.

I got fastboot working by plugging the phone into a dedicated AC power charger, not one with a USB adapter. Then I let it sit on the boot screen for a couple hours. This way it fully charged the battery and I could bring up fastboot.
What was happening with the USB adapter was that it would try to boot, die, and refuse to go to fastboot, over and over again. I would not have got it working without a dedicated AC power charger.
That literally happened to me a few days ago. Fastboot will say a warning on the screen, somewhere around the middle, "Battery Low" or something along those lines, I paid it no attention, as I knew it was plugged in and should've been charging through my processes. Well, the battery has to be at least 50%+ charged before fastboot will allow any connectivity or communication with ADB or Fastboot on pc. Facepalm.
Always double check battery charge at least 60% or more to be in the safe side, or you risk to soft-brick to even hard-brick your phone.
Sorry if I explain this horribly, will try and be as descriptive as i can.
Was using CM 10.2. Had a problem, which I was on the way to fixing. I was having an internal storage fault which was fixed by using stock recovery, could then flash TWRP back and everything worked fine. Then one day it all decided to die. Phone would just get past the HTC logo screen and would then die before booting Android. I could however get into bootloader/fastboot/recovery ok. However could not mount internal storage-windows wasn't picking it up when plugged in, so flashed stock recovery again and this seemed to make it mountable again. So was able to put CM 10.2 back, so re-flashed CM with no joy, wiped caches and data etc, still nothing. Didn't want to boot Android. Boot.img was flashed and everything. Went back into bootloader, however upon unplugging the USB cable, the phone turned off.
Tried turning the phone back on and it just showed the HTC logo screen for a slit second and died.. then showed it again for a split second. Does the same for the recovery screen if you hold down Vol Down and power - shows it for a split second and then dies.
But if you plug the charger in (orange light comes on) and turn it on, the orange light goes off.. stays off for a moment..and then comes back on, phone does not turn on. BUT if you press the power button and the orange light turns off and then you quickly hold the Vol Down and power button at the same time (before the orange light comes back on) it will bring up the bootloader.. and it stays on. I can try booting and it shows the HTC logo screen as normal but then turns off again before booting android (same problem i was having before the charger issue). I can go into TWRP recovery no problem, i did factory reset for good measure while there but the moment you remove the charger, it turns off. Its like the battery is totally dead but TWRP shows it as 90+ %
If you leave it to charge completely and the orange light turns green. It WILL bring up the HTC logo screen as normal (not for a split second) but eventually turns off again and doesn't boot android. Green light then turns orange again and it only shows the screens for a split second.
I've flashed this phone with a couple of ROMS before and have had my share of issues but nothing like this, i'm stumped. I think Android not booting up and the charger issue could be unrelated but I could be wrong, never faced this kind of problem. Been looking around, cant find an issue like this, i fear it could be a hardware issue as supposed to a battery calibration issue.
I would like to drain the battery completely and give it a full charge just to see what happens but i cannot keep the phone on without it charging, so cannot drain the battery...
Any help/advice/suggestions would be much appreciated.

I tried to understand as much as i can and it seems like a corrupted BL/recovery .Have u tried flashing your stock rom?If there is still a problem , then it may be a hardware issue . Try contacting HTC service centre if it's a hardware issue.
If it's not a hardware issue then try flashing some other room and recovery.
My tablet was in my bed and I went out. When I came back, it's in infinite loop. Other times this has already occurred and I fixed it.
So, yesterday, I tried to do this. But when I selected "Wipe Cache Partition" in boot menu, the process was taking too long and seemed to be freezed. So I pressed the Power Button and turned off the tablet. After I tried to turn on the device again, but anything happens. No boot, no Download Mode, on the Android Menu. Nothing.
I already put it to charge, tried to connect to PC, but nothing happens (the PC not recognize anything). No screen signal or noise. When I put it to charge or connect to PC, the device warm up to bit.
I already opened the device, checked the battery status, with a multimeter, and did a manual charger. But still, nothing happened. (The battery is OK)
Is there anything that I can do?
I need my device and some files. In my city haven't a place to Advanced HDD Recovery, and the Samsung's Technical Assistance is in the capital.

Do you see any light coming from the screen when booting? The screen could have failed or the light. You can try to take a flashlight and put it on the screen to see if you see any boot animation when you turn it on. It sounds more like a hardware issue.
Have you tried to plug the tablet into a computer? You maybe able to recover the data that way. Samsung might be able to repair or recover the device, but if it is out of warranty you may have to pay for the service.

I don't see anything! I'd plugged into a PC, nothing happens! I think only at Samsung Technical Assistant... But I dont have warranty anymore, so have to pay for this!
