Hi,
My Universal fail to power on.
It do not enter boot loader with light + power + reset and show no signs of life. Batteries are both new and tested in other working units.
When connected to USB, PC reports "USB device not recognised"
I had ROMS flashed but failed at 99%. When reset the units did not power on or showed any signs of life.
It had been working fine up until the unsucssesful flash update.
I would like to be able to use it for work .

Please try to enter the bootloader mode in a bright room as it is very difficult to see in poorly lit environment. Till you enter the bootloader mode your device will not be recognised. Perhaps one of the three keys is getting released..the light button is the usual culprit. Once you are in the bootloader you can reflash.

Thank d_ranade for your answer.
I am sure the screen is 'all black' and I've tried to press the buttons several times.
I think the main problem now is how to enter the Bootloader.

I sometimes find it takes several goes to get into Bootloader mode. If not, have you tried a hard reset?

I've tried whatever i can do. Hard reset is useless too.

Unable to start/see bootloader
I seem to have the same problem with my upgraded universal which was working fine for about ten days. Then I installed TomTom on it and again it was all working that evening.
Then, when I turned it on the screen went blank (white), so I re-flashed it, but, part way through the screen went black, so I left it connected for further hour and nothing. I have since been unable to get it to do anything, it is not recognised by activesynch, it will not charge (either from the mains or the USB on either of the batteries) nor will it turn on or respond in any way.
I have unset ‘allow usb connections’. I have tried solidly for +/-10 minutes doing the backlight + on/off button and reset bit - repeatedly, with my wife helping to ensure all buttons were being pressed. All I got was a message from MicroSoft telling me that ‘One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it’. The only positive thing is that every time I do it and depress the reset, the red LED flashes (provided I leave the USB cable in) but at no point have either of us been able to see any writing on the screen.
Any guidance (apart from where to take it for recycling) would be welcome…

It happened to me several times too. Even in the old ROMS. But had learned many things out of it. I removed the battery. Wait for several seconds or maybe minute before placing it back. And after placing it back wait again for some time before doing the "power + light + reset" (bootloader). At some point when I am in the bootloader mode already and reflashing, connected to the PC already, the screen went blank again. So I'm sure that something went wrong again. I repeated the procedure again (removing battery, placing it back etc...) and the reflashing continued. It takes patience (maybe).
After having experienced this so many times, I'm beginning to assume that it is not because the battery is "bad" or there is a problem on the ROM being reflashed. It is on how it (the battery) is connected to the unit. The reason why it does not turn on, charge even if connected to the charger, does not hard reset, does not react to anything... I just don't know.
One thing more, the procedure I said above sometimes does not work at once. But at least I managed to "resurrect" my device several times.
This I am sure, it is not in the ROM that is being flashed or the update...
Hope this helps,
Lelen

lelen, Thanks for your assistance. I tried last night, but it still could not enter the bootloader mode...

I have the same problem =( and i don't know what to do, someone told me that i have to change motherbord to resolve this problem, i hope there are some other solutions.

Dead Uni
I too had this problem. With the device not responding at all and not able to enter bootloader stops mtty from working.
Only way i could get it to work was to take it to an O2 shop to send it away for repair (luckily the O2 XDA range has a 2 year warranty and because its completely dead they cant tell the OS has been modified).
Unfortunatly like the previous post i think it can only be fixed by replacing the mainboard.

Hi all, i found this thread http://forum.xda-developers.com/showthread.php?t=291097&page=6
so many people have the same problem , and nobody found a solution? i can't believe that on all this universals died motherboard, and there is no way to fix it with some special cable or some programm.

yes,i post the last reply of the thread you mentioned above, but nobody can resolve it.

I recommend you remove the battery and leave it over night. Put the battery back on, ensure it is properly mouted and try booting it.
It worked for some, no idea why though. I'm actually suspecting a bad battery mounting, which results in the motherboard unable to detect a battery is iserted, thus refusing to boot.

finally managed to get mine fixed, mine was out of warranty too and sent it off to carphone warehouse express service, took 3 weeks but was fixed with a standard chargeable repair charge of £40

I have a somewhat similar problem but not from upgrading. I accidentally dropped the device after a successful upgrade and the screen got damaged. Someone picked it up, opened it and noticed it was on even though the screen was damaged, and then closed it back. By the time I got it back it was dead and could not come on again. I have since replaced the damaged screen, but the device will not come on and cannot enter bootloader either. The device get warm if the battery is left on.

i780 cannot be charged!

Hi,
I have read a lot of topics about my problem but I haven't found a solution.
I'll explain my problem:
I have successfully flashed a samsung i780 with the Heroes WM6.1 Final ROM using mirage 1.8.
The phone works well for a couple of days, but one day it crashes and I perform a soft reset. It reboots normally but the dispaly shows the touch screen calibration and the contacts are disappeared. So I think "This seems to be an hard reset!!" and it happens a couple of times.
The last time it crashes the battery was very low. So I shut down the pda and I connect the charger, but the red led doesn't turn on.
With the portable charger the battery charges without any problems, but when I insert the battery, the i780 doesn't power up.
I try every combination: fn + alt + power / power + red and green buttons / power + '9' button. The pda still dead and mirage cannot detect it.
Somebody can help me?
Thanks a lot and sorry for my english.

no idea?
somewhere i have found something about jtag connection..

did u try this http://forum.xda-developers.com/showthread.php?t=380723

@ironeagle
The device goes completely dead and you cant put it to bootloader mode, or anything at all for that matter. The device goes COMPLETELY DEAD - literally! The service guys told me it was a mobo failure.
@sfrangebob
I think inertiax did mention somewhere that someone was able to revive it using jtag interface. But for that you need to hack in at hardware level and flash the chip directly. This is risky and has no assured outcome!
let us know what happens....best of luck

it's not a problem for me hacking in the hardware level. I have a lot of experience in consoles (and electronics devices) hardware hacking, but I have to discover more about this jtag method.
Wich jtag adaptor should i use and wich software?
Where can I find this information?
Thanks a lot.

The biggest problem is to find JTAG testpoints for the i780. I have no idea how to find this, and it was only inertiax who had mentioned someone who had successfully used JTAG to revive a dead i780...so i'm guessing he should know where the jtag test points are located. Once you have that, i guess you can borrow the process from that of any other device as it should be more or less the same.
You can see this post -
http://forum.xda-developers.com/showthread.php?t=369681

You can download i780 sevice manual on the internet and find out the jtag test points.But there are two types of jtag test points on the mainboard.

perhaps this may fix up ...
took out / in the battery for several times ... do it quickly
then try to turn it ON ...
I got the same problem as you ...
but mine when I took out the battery or turn OFF,
it cannot be ON later...
so I repeat the battery in/out several times and its work ...

Repair bricked phone

Hi everybody!
I have an almost 2 years old DHD which I think is completely bricked. It was working for approximately one years perfectly and then suddenly it stopped working. Whenever I tried to turn it on, it only vibrated once and did nothing more. Sometimes it turned on and these working periods were enough to restore to stock condition (It was rooted and had Eng S-OFF before.). I had brought it to service and they said they was not going to repair it as the device got water damaged. I'm pretty sure it was not! After a few weeks, it started working again. I was using it for 3 months then it bricked again and it's the situation today as well.
Previous week I looked into the development thread and saw all of these new amazing roms. So I took my DHD to see if it's working or not. The situation is the same. Everytime I power it on, the phone only vibrates once and nothing happens. I'm not able to get into hboot mode. At some very rare occassions the phone turns on and works flawlessly till reboot. When I connect it with USB, the computer doesn't recognize it. Battery is charged, I even tried another battery.
Does anybody know what happens with the phone? I'm open to any possible solutions to try. Please don't suggest to bring it to service or repair it, because I have another phone, just want to try to recover it and ask your ideas about the problem.
Thanks in advance!
Greetings,
Adam

So you say you cant enter in fastboot or recovery?

Since it's intermittent, my guess is it is a hardware problem. Some kind of bad contact/loose connection. Make sure everything looks good on your battery door and the battery contacts inside the phone.

I cannot enter into hboot mode. Didn't try recovery, but assume it's the same.

I also think it's a hardware problem. Will take a more careful look at the battery.

Wrong sub forum buddy, post in the One V Forum.

Its possible that there isn't "water damage", but there could be moisture getting into the phone causing it to act erratic. To cancel out that possibility, submerge it in a closed container full of rice for a few days

HTC One X APX Fix?

My phone randomly shut down in the past days but I always managed to turn it on again (by pressing random buttons and connecting it to the wall/PC), yesterday I decided to flash a custom ROM (CM11) in hopes that it won't turn off again, but today I restarted the phone and now it's in APX mode and won't turn on or charge.
I've tried to find an answer here, on XDA but found nothing (There's this apx driver but download page is broken)
What do I do?
I've brought the phone from one of my country's E-Bay(ish) websites, so I have no warranty, and I don't know if there's any HTC official center in my country.

APX = a dead hox. Nothing you can do really. Changing the motherboard is the option. All solutions that may seem to work is just a temp fix if you get lucky.

[Q] [HELP] HTC ONE M8 | Dead / Bricked?

Hey,
Last Week my HTC died. It turns off and won't start anymore.
No light, nothing.
Battery is at 30% as it shut down.
Power + vol up / down doesn't work. No recovery mode..
In the Device Manager i found the HTC, named "QHSUSB_DLOAD"
Is it Bricked?
I found this Thread but it's for the M7, not M8 :

Many Thanks,

Edit: My Englisch is not very well, I'm from Germany

I am not HTC Expert, but from what i know, it maybe got motherboard failure, maybe u should go and get replacement. If u got no root, and it randomly went off and not get on back again, it's for sure then a hardware failure, it mostly is caused from the motherboard. Also, your screen might be damaged too, the cable that is connected to a port to light up screen, maybe something there popped off, so ur screen went full black? also, try to take battery off, and back on again and start the device like u normally do, and find a way to get your phone make sound or vibrate, im sure there is a way, if it doesnt work, it's for sure from what i know, hardware failure.
Anyone would say same i guess, good luck.
