Lumia 720 froze during unlock bootloader - Windows Phone 8 Q&A, Help & Troubleshooting

Hello
i used Windows Phone Internals 2.9 to unlock bootloader and the phone froze with grey screen after finishing 1st part, it asked to manually reset and it froze. and 5 h later is still frozen.
with the same program, WPI i can see the phone is in the mass storage mode and is waitng for that manual restart i cannot do, no matter how much 20 sec at least i keep the power pressed, or power with volume down or other random combinations.
in the image is what i see with it connected on the pc
is it dead?
it had this problem with the reset before - (it froze from time to time), sometimes took a night to restart or drain the battery to reset
thank you

Diamond reboot loop w. original ROM

hi there,
this morning, without any interactiom, i heard the vibration of my touch diamond restarting.(with original newest ROM from htc website that ran without any problem for several months). battery was about 80% yesterday evening.
but it wasn´t starting at all. after the HTC animation and the green windows mobile screen, it started again. after restarting for 20 minutes i took out the battery, put it in again and performed a hard reset as stated in the manual.
now, on the "rainbow" screen i get a message like
psoc diam stage_pvt 0x32
then i did the Volume-Up reset, and now i don´t even get the red version information in the lower right screen. as it doesn´t even start i cannot get an active sync connection.
any ideas? is my phone broken? i didn´t do anything special, and i wonder why it rebooted without interaction this morning.
any ideas what i can do?
thanks in advance,
jkersch
Mine started doing this about 2 weeks ago it woke me up in the middle of night while sleeping with its vibrator and start sound.
The only thing I have found is that my little reset button at the pen holder dosent work anymore. To do a hard reset i have to takeout the battery and then put it in, hold the volume key and enter key then power it to get it. Flashed by holding volume down and the power on, it hold for about 10min just enough to get the flash.
I managed to flash it once but it dosent help, it constantly reset at the thouch diamond screen. Some times i get to the green windows mobile screen.
As warrenty is out on my phone and ive given up and using another phone.
Same problem in a different thread

Bricked Xperia T

Hello, I'm having trouble with my Xperia T.
It's an unlocked bootloader with the latest DoomKernel on, CWM is installed and the FW is .145
It worked fine 'till today morning. Last night i put it to charge with a nokia charger that i've been using before and this morning it was non responsive and the green light is permanently on. I tried hard reseting it for a number of times, still non responsive.
I'm running out of options. Any ideas?
Can you get into fastboot mode?:
Unplug und plug in the USB-cable. Hold Vol+ and the ON-button at the same time for a couple seconds until you feel a single vibration. Let go of the ON-button but keep the Vol+ pressed. You should be in fastboot mode again indicated by the blue LED.
If that works, you can reflash the original kernel.elf or boot.img with fastboot in order to get the phone working again.
I am familiar with the fastboot mode and also to the flash mode.
The phone is unresponsive to any key stroke combinations. I've done the Off+ Volume Up or Volume Down or even with all three at the same time for more than 20 seconds and it does nothing.
The phone should be on since last night i charged it whilst beeing on.
I'm starting to think to phisically remove battery...
Did you try everything from the recovery thread: http://forum.xda-developers.com/showthread.php?t=1849170
You said you did a hard reset. Are you sure (three vibrations)? If that is the case, maybe this is your problem (from the thread above):
ATTENTION:
If your phone is not working but you see a led or have bootloops DO NOT USE HARD-RESET. This can make your phone lock/freeze up until the battery dies. It took 51 hours for mine to die.
However if you get stuck on a boot screen or get bootloops a SOFT-RESET may work to reboot.

I had to do a hard reset too once or twice. But mine never locked up. I don't know which conditions lead to this behavior.
So try to wait till the battery is completely dead. Then charge it for a while. Turn it on, and it will get stuck at the faulty kernel again. But this time only do a soft reset (single vibration), combined with the fastboot key scenario (like I described above).
If nothing works, maybe the rubberband trick might be a solution (also in the thread). But I have never tried that (never needed to).
I tried to do the hard reset but it does nothing. So after 24hrs the green led is still on and nothing happens no mather what key stroke i try
Update: I disassembled the phone and did the hard reset manually and all is well for now.
Thanks for the replies

Alright. Glad you got it working by removing the battery. I guess it's true then that it takes forever (50+ hours) for the battery to go empty on a stuck hard reset.
No, actually mine was 80% after 30 hours so i guess it will take more!

Xperia Z... freeze and brick?

Hey there,
So today I was using my Xperia Z aaaand bam, phone "died".
Battery was at that time 70%, phone was a little bit hot, but in scale of 1 to 10 it was like 6. I had not problems previously with it (besides broken screen that got replaced 3 weeks ago). I was playing a game then suddenly it got closed and my screen got shifted. Like Animation of horizontal menu stucked while going to vertical. I pressed power button many times, I've keept holding it for a short time, long time... nothing. Phone did not respond at all. After 10 minutes it went black. No idea if it went "sleep" or so since power button do not work again.
I tried to reset it with Power + Volume down, Power + Volume up and again, nothing.
I've tried factory reset with Sony Companion but no luck either. Phone is NOT detected by that program.
However, when I plug the phone to PC I hear sound that some device has been found. Phone is presented now as QHSUSB_DLOAD in device manager. I've heard that not a good sign...
When I plug it to PC or Charger nothing happens so I have no idea if phone is getting charged or not.
What even more confusing, when I press power button - nothing, phone is COLD. But when I press Power + Volume down after a while it starts to get warm, after a long time of repeating this really warm.
Any ideas what could I do?
Thanks!

You phone has locked or unlocked bootloader? If unlocked, give a try to enter Fastboot mode and flash any custom ROM

can't switch off and eternal boot loop

Hi guys,
Funny thing happened today, taking the phone out of my pocket and in the process i manage to restart the phone and it has been restarting ever since......
Its a 1068, rooted with radium redefined MM rom. The phone has been great for 2 years and i had no issues until today.
So basically the phone continues to restart back to the unlocked bootloader screen and then restarts again.
Nothing i have down can actually switch it off, all manner of pressing sequences etc and for various lengths of time have no effect. You think okay i have it now....it's off.....but then 3 secs later it turns back on again, vibrates and does it all over again......
I ended up taking the phone apart and disconnecting the batter cable and left it for a while, plugged in the power only and then reconnected the battery hoping this would somehow help........but no.....the eternal boot loop continues.
No way to switch off the phone.
Can't access recovery via the power and volume keys
Can't access recovery via pc with adb
I read somewhere that with a low battery this boot loop thing has happened to others but i couldn't find the thread again and have no idea if there is a fix.
Anyone have some bright ideas ??????
Thanks in advance

Dead Lumia 925 after unlock bootloader fail

Here's the story:
I was tried to unlock bootloader my lumia 925 by WPinternals. When it was about 31% app crashed and exit, I tried restarted app several time. but it still crashed. I held the power button to turned it off and when I reconnected the phone nothing happened pc not shown any new connected device and the windows button on the phone keep flickering. When I hold power button or any combine button the phone just vibrate and the screen just black. I've tried every flashing method but my pc not recognized so nothing worked. So what can I do to my phone. Is there any how to make my pc recognize the phone.
Thank for reading and help .

First of all you should try to charge the 925 for several hours. Normally, a lightened Windows button indicates a completely drained battery. It will take quite a while until at least the charging symbol appears on the display. Later on you will see if you arrive at QSB in Device Manager or if you can return to flash mode.
Best wishes,
Joachim

I tried and charged it for almost a day but nothing happened, my computer still couldn't see it.

it same happened with me and I used WDRT and it detected my device..
Dude... You have a dead-boot lumia.
Solution: JTAG (cuz my method of unbricking dead-boot lumia is not working, boots to QUALCOMM Modem Mode)
