EMERGENCY - Total Brick Instant Bootloop

Screen went black.
Pulled battery.
Battery In.
Plugged into PC.
I get OMAP4440 in Device Manager for 0.8 seconds then instant dead phone.
OMAP4440 comes back half a second later then back to dead phone.
No Fastboot, No LCD, No Nothing.
DEAD Battery, I will keep it plugged in overnight, the USB may not be giving it enough voltage for the boot.
Any help greatly appreciated. There is not enough time to flash anything while the phone is actually "on" for the 0.8 seconds.

What caused the screen to go black? Did you flash something right before?
I mean this is no regular boot up, you obviously attempted something right before boot up!

why not charge in the wall in the mean time? (just curious)

See if you can get a hold of one of these: http://www.amazon.com/SainSmart-Don...73JQ/ref=sr_1_1?ie=UTF8&qid=1326592299&sr=8-1
When you plug it in, it boots the phone into ODIN mode.
But yeah, firstly, try charging the phone up first.

any way to charge a phone once completely dead

any way to charge a phone once completely dead
as the title states, once in the bootloop issue if your battery ends up at 0% and can't be charged is there a way out of this. Here is my issue. I can't get into recovery. Hboot or fastboot are the only options available. Sometimes it boots into the ROM but instantly dies once restarting. No clue as to the trigger as I've tried pretty much all the combinations of factory reset, reboot-bootloader, erase cache etc etc etc trying to get this into a non on mode so it can charge.
In addition to this of course anytime I plug the phone in it automatically turns on in either bootloader or fastboot which gives it no opportunity to charge at all otherwise I would simply run the RUU which won't let me until it hits 30%. I've more or less come to the conclusion I have to send it in because its not quite the same situation that others have experienced. But was hoping to get an answer/fix so I don't have to send it in to HTC to get repaired since the RMA guys just told me it'll be 10 business days before they even get in parts to the texas facility to get it sent there for repairs.
also of note, I had managed to relock the bootloader but can't get enough juice to run the RUU

What about borrowing a battery or getting one and charging it. That would be better than sending it in.

With the current recovery. The phone can't charge while off. You can't let it die

yeah so far I've tried literally everything out there. I almost need a way to figure out how to wipe the rom so it can't restart and sit on the loading screen so it can charge, but so far no luck with anything in the forum. I've literally tried it all.
Could be worse, my replacement comes today (but cost the same sadly, looks like the gf will get a new one when I can send it out to htc for repairs and get it back)

So, when you plug the charger in, the phone starts up into hboot or something? And can you not press and hold power for 10 secs to force it to power off while still plugged in? My phone was charging while it was completely off. That's after I discharged it completely, it shut itself off.

any time I plug it in it automatically turns back on. If I hold down the power button for 10 seconds it simply reboots.

By either plugging in every time it stops charging or rebooting it like that you should be able to gradually charge it over 30%, that's what I heard. So it's not as easy as plug in and wait, but rather plug in, unplug, plug back in.

I have this same issue. Arent their any recoveries that charge while in recovery mode??

Yes.. The stock recovery. You need to flash that.

again, can't flash diddly because of low battery. So flashing stock recovery does nothing as it would end in an error.

Very possible solution! Worked for me!
It seems my reply via the XDA-App did not come through.. As I wanted to reply.
My H0X was also dead. Wouldn't charge nor boot, with wall charger or by pc.. but I thought.. well let's give it a chance by using my iPhone 4 charger (with HTC cable of course)
Guess what: It worked!
SO TO ALL WHO IS HAVING THIS 'WILL NOT CHARGE' PROBLEM:
Try an other charger, even try your wireless mouse, or other phone chargers.. Anything!

you don't think something silly like this idea has been done? When the phone is plugged into any outside source of charge, it turns on in bootloader. This does not charge it...

Get into fastboot and try charge ..same happened to me when I tried to install Mike's Rom. So what I ended up doing was after trying a millions things to get a little charge so I could flash stock recovery and relock bootloader. I turn phone off. Plug charge for 2 seconds unplug. Plug again unplug. Big pain in the ass. Don't let charger to long cause it boots phone againg. So usually u see led turn on then few seconds later it goes off that's when u have to unplug charger. Do that again a few times. Enough to get a little charge again to flash stock recover. Once u flash stock recover phone charges normally. You also need the correct RUU for ur phone. That's after flashing stock recovery then relock bootloader then flash ruu. Then u can try again a custom Rom or whatever u were doing

I faced your situation once
get into the bootloader and flash back the official recovery

[Q] Am I bricked? attempt root won't turn back on

So, I finally got my Ubuntu udev rules set up and got my Kindle communicating with adb and fastboot. I went through the rooting kindle 6.3 process and I only made it to
fastboot -i 0x1949 flash bootloader
fastboot -i 0x1949 flash recovery
this is from:
http://forum.xda-developers.com/showthread.php?t=1568340
adb sent them to the kf, but the next step it says is your kindle will now boot into twrp and flash firefirefire. Well mine didn't it just stayed on the Kindle Fire screen, no reboot. I left it alone for about 20 min, then I think I probably screwed up by holding the power button down. It took about 10 sec then it powered off. Now it won't power back up. I'm worried that now I have no fastboot and no recovery?? Anyway any advice? Or at this point do I try to get amazon to warranty?

What is the filename you flashed the bootloader with?

I downloaded all the links, and I renamed it to fire.zip, and i renamed the twrp to twrp.img, just so i didn't have to type out the entire filename.. Is that a mistake?

sometimes I get lucky and plug it into the normal wall charger and it will wake it up

You don't flash a .zip file directly to your bootloader. That's a hard lesson to learn your first time around. It's a fairly pretty simple fix but you're going to have to make a Linux LiveUSB and pull the back cover off.

So I finally decided not to send it back and to just fix it.. I actually already have a successful linux setup.. So I did the pull the cover, short the pin, and nothing still... I'm about ready to give up on this thing.. Any suggestions? Anybody know if I can exchange from Amazon still? I'm assuming not

Do You think maybe my battery drained? It has sat for a while.. I just plugged it in to the "kindle" charger.. I'll see what happens in a couple hours.. The terminal is looking like it is good to go.

tried again after being plugged in for a while, still nothing. *sigh

There are a few things that could be going on. Your battery could be dead. Even in that state the power could still be on draining your battery but in most cases it doesn't take much to flash a new bootloader.
Before you try the shorting trick, hold the power button for 20 seconds or more to make sure the power is completely off. In Linux, make sure you are running firekit as the root user. Shorting the pin can be kinda tricky. I've seen that it works best with a pair of sharp pointed tweezers or a safety pin to keep everything static while plugging the device in. Sometimes it just takes a little perseverance to get the timing right so keep working at it.
In the case that your battery is just too dead to do anything at all, you'll want to get a factory cable. The factory cable bypasses the battery and powers the device directly which would eliminate the need for a decent charge.
In either case, it's all just a matter of not giving up on it. I would say that 99% of the time, if everything is done correctly, the firekit will work.

Awesome, I am doing the usb setup with the firekit just to be safe.. Thanks for your help.

Same Here
I followed the same guide to the same step and had the same problem. I also let it sit for a while, nearly an hour and then I shut it down by holding the power button. I will let it sit on the charger this evening and see if it will boot later. Otherwise I may try to send it back to amazon. Their customer service has been pretty great in the past.

Anybody fix this problem yet? My KF is doing the same after following the same root process. Won't power up, won't respond in any way. :crying:
I haven't tried opening it up as I don't want to void the warranty. Would a factory cable work instead or should I not bother? TIA

Plug your charger into it and see if a bootlogo appears on the display. If it does not, then the odds are your bootloader is broken and the only way to fix that is to open up your case and use Firekit. A factory cable relies on the bootloader to put the device into fastboot mode, so it won't help you if your bootloader is broken.

Thanks kinfauns (and previous posters)!
I did finally decide to open it up and try the Firekit solution. I'm kind of shocked I got it to work, ha ha. Everything is right as rain now so thanks a million to all who suggested it here and on other threads!
FYI I used some guitar picks, a license, and a metal collar stay to open the case. A couple light marks on the very edge and a very slight gap now, but otherwise the case is fine. (Pretty sure no one but me will ever notice.) I used a piece of solder wire to short the pin, a stiff paper clip would probably have worked better though. KF kept sliding at plug-in so I set it against a medicine ball to hold it, lol. I got the trick to work on the second try. (Actually maybe the solder wire is better since flexibility made the connection easier to press firmly.)
Went here for instructions and pics on how to do the short trick: evilsoapbox[dot]com/?p=1444
Thanks again!

HTC One X Won't Power On Or Charge

Hey, I got a HTC One X today and used it for about 2 hours, and after going into location settings the phone froze for a while, then eventually it switched itself off. I couldn't get it to switch on, and when I connected it to the charger, I noticed the LED was no longer lighting up when connected to the charger.
So I done some reading, and heard that if you hold the power button for 10 seconds, its basically the same effect as pulling the battery on other phones. So I held it for 10 seconds and the phone booted up, it got the the lockscreen straight after booting up, when I tried to unlock it, I realized that it was frozen again. Then after a while it powered itself off again, so I tried to power it on, once again it was not working. So I tried holding the power button for 10 seconds, this time its not working, no matter how many times I've tried it doesn't work.
The phone wasn't rooted, I never done anything to damage it, I read that if you hold the power and volume down it will go to the bootloader, where I would be able to factory reset the phone, but even after hold those 2 buttons, still the phone is showing me no sign of life.
What should I do?

try to put in under charging, is the led red?
if it is, wait 10-15 minutes and try to go into fastboot with power button and volume down, and do a factory reset, or fist you wipe all your things try again to boot it up, maybe it was just without battery charge. is your phone new? or it's secondhand?

The phone is second hand, but condition wise its practically new, there's doesn't seem to be any damage, and its still under warranty, the seller said that he never had any problems like this.
When you says "put in under charging" do you just mean charge it? If so I have done that with both the computer and the AC adapter, and the LED is not lighting up.

Try plugging the phone into your PC via the official usb cable,
I know you've done that, but Whilst it's plugged in, press volume down & power at the exact same time and keep them held until your bootloader screen shows.
The good news is, I've had this happen to me - i just kept trying.

Yeah, I you should be leaving it plugged in.
Next step is to get Android SDK installed on your pc, even though it appears to not come on, you might still be able to run a fastboot charging script that will force your phone into its bootloader.

Update your packages on Android SDK
place the fastboot charging script in the same folder that fastboot is located on your pc
Usually: C:/Android-SDK/platform-tools
Double click the script
I have the script, it but won't let me share it to you.
It's on XDA though somewhere.

Leave the phone connected to the charger for a few hours. If it doesn't want to work, try pressing various combinations of volume and power buttons. Otherwise I suspect you have a brick.

The thing I notice aswell after leaving it charge all night, is that it doesn't even get slightly warm. I can't believe HTC get away with releasing faulty crap like this. I had a 2 hour teaser before this started... Good job HTC.
Edit : Oh well, I gave up, I tried everything and anything and it wouldn't work, so I've sent it to HTC for repair since its still under warranty.
Edit2 : It took them a while, but there finished repairs now, and its on its way back to me. They replaced the Mainboard and the battery.

hello..just for sharing,.just now i woke up from bed and see that my phone cannot turned on.. you know what, during charging last nite, i forgot to off the screen(press the on button) so that my phone screen was kept turning on all the night,,.. i'd try to connect it with the charger but it still didnt work.no LED at all. after i read the comment from some of u, i decided to connect it to the PC .. fortunately, the red LED came out..
after wait for sometimes it was turning on..but sometimes can turn off back... its because of the bttery.. anyway, im so happy now.. hahha :laugh:

[Q] Completely Bricked Kindle, could use some help.

Long time reader, first time poster. I've been coming here for years for all my Kindle needs, but unfortunately I'm a bit stuck, and I'm asking for some help.
So I have an original Kindle Fire. Back probably in 2011 or 2012, I rooted the device and installed a custom ROM. I didn't exactly know what I was doing, but I read some tutorials and followed them carefully, and everything seemed to work fine. I avidly used it until I bought newer devices. I ultimately lost interest in it. It traveled with me from house to dorm to apartment.
Now just recently I get it out, and the thing won't start. Completely dead. The screen won't light up; the button doesn't glow; it is completely unresponsive. From what I've read, this seems to indicate that my "bootloader and recovery ... are broken".
Following some other help threads on xda, I was ultimately directed to pokey9000's Firekit LiveUSB repair kit, where I installed Ubuntu, opened the Kindle, performed the "USB Boot Shorting Trick", and through FireKit, managed to successfully send USB-Boot commands to the Kindle:
the Kindle powers on and displays a yellow triangle with fire logo inside of it. The kindle says something along the lines of "press power button for recovery", but that doesn't do anything.
On my computer, FireKit hangs at <Waiting For Device>, and nothing happens.
I feel like I'm so close to fixing it, I can't just give up. But I honestly don't know how to proceed; I'm stuck and asking for help.
I take it, the yellow triangle is an old version of FireFireFire. Does this mean I'm in FastBoot? Ostensibly, shouldn't I be able to reboot into Windows and use a tool such as Kindle Fire Utility or Kindle Fire Unbrick Utility to send fastboot commands, and fix any problems from there? Because that doesn't seem to work.
Willing to throw some Walmart or Dunkin' Donut e-gift cards your way if you can point me in the right direction.
Thanks in advanced. :good:

I'm guessing that the battery is dead, and that is all.
Can take hours even days to on Wall charger to see progress.

Nah, I left it in the corner of my bedroom plugged in all by itself, just pressed the power button a few times a week to see if it would power on. Only tried the one charger, which charges other devices just fine. Seems to be a 'high-power" charger because on a working Kindle, I do not get the message "Connected to Low-Power Charger".
I'm pretty sure the battery is charging. A few weeks ago I usb-booted and left it sit at the (fff?) yellow-fire-triangle, device unplugged and screen constantly on. It stayed that way for at least an hour, before I manually turned it off. So that would lead me to believe the battery is in good shape, and the USB port is fine.
Could give it another week or so with a different charger. Got nothing to lose, I suppose.
Thanks for your reply.

Sent from my XT907 using Tapatalk

Have you tried using a Linux OS? I've seen lots of threads/posts all over XDA about how people can't get their device to work with Windows. Maybe you could grab a live version of some OS and put it and the binaries for adb and fastboot on a flash drive and boot from it. The only time I've ever had issues with my devices and Linux is just recently when I discovered a faulty USB cable (is your cable good?).
Perhaps it may be easier to just replace the motherboard. I did that when my USB port got wrecked. The best deal I've found is here: http://www.powerbookmedic.com/Kindl...-REGISTER----Good-Micro-USB-Port-p-27164.html If you don't intend to run Amazon's OS, then it doesn't matter that it can't be registered. If you do replace the board, be very careful of the data cable for the LCD; it is fragile.
