Note: This is a re-post from the Verizon HTC forums (http://forum.xda-developers.com/showthread.php?t=2533042)
I just rooted and S-off my HTC via rumrunner.
No flash roms install or custom recovery installed.
I wanted to see if I still had CWM from my last root (I returned to stock via http://forum.xda-developers.com/show...highlight=s-on.
So I went into the bootloader or fastboot (I don't remember) and hit recovery. This did not send me to a CWM, but it appeared to be the stock version of recovery. The process took too long (I know impatient) so I turned it off via power button + volume down.
Now I come to you in need, my phone is constantly turning off/on only displaying the green htc text, no red text, then pausing for 8 seconds, then off again to black screen. The whole process lasts 12 seconds, and this had been going on for about 10-15 min atm.
Plugging it in, my computer does not have the time to recognize it with adb, or fastboot.
I cannot use the power button + volume down to go into bootloader, and pressing the power button does nothing.
Please help me.
So here's the update.
Screen is now black, meaning the boot up/down process has stopped.
I have tried these:
A. Hold down the volume down + power button for 20+ seconds.
B. Hold down the volume up + volume down + power button for 20+ seconds and let up on the volume up button when screen goes black.
These two methods results in a single boot up to green HTC text then black screen.
I suspect the device has lost most of its power. Tried it for a third time, the device is now unresponsive and remains at black screen.
Now I plugged the usb cable connected to the power adapter.
The device enters the aforementioned continuous boot loop.
I tried method A and B, and there are no results, the boot loop continues. Now the device returns to the low or no powered state.
Now the device is connected to the computer. The same happens as if it were connected to the power adapter.
Method A and B still do not work.
Results: holding down buttons longer do nothing for me. The device seems to have lost power, but when charged, immediately the device enters the boot loop state.
Note: when doing method A and B the trials were done when screen is on and when screen is off, still no results.
Now the screen is off and not connected to anything. The problem still persists.

If I had to guess I would say your volume down is broken, else it would enter hboot
plug in the power and let it charge all day. then plug it to your pc and try to adb reboot bootloader or adb reboot recovery the instant you here the pc usb ingage.
once you get to the bootloader try and fastboot erase cache followed by fastboot reboot
after your phone boots you should be able to go back to bootloader and reinstall custom recovery

I have a few questions/concerns to this.
1. When I charge it, I can't stop the phone from the continuous boot. I'm afraid that doing this all day might hurt the phone more.
2. Currently I have been charging it via computer (still boot loop), and the computer does not recognize it at all. I think there is really not enough time because the loop duration is only a few seconds.
3. Since the phone is connected to the computer, the commands adb reboot bootloader and adb reboot recovery does not work. Error: device not found.

well have you held the phone under a bright light and held just the power down for 15 seconds and let go when the phone go's off ?

So what is this method supposed to accomplish?
I did this and the phone stopped the continous boot. However when I tried to go to hboot it went back into the loop. I did this twice, and I'm able to stop the loop with the bright light method, but I don't know what to do from here.
Note: when plugging phone into computer, the loop starts again.

Plugging the phone into the adapter, the phone charges, but the boot loop occurs again.

the phone should not bootup with the power cord plugged in from an off state (are you turning the phone back on ?)
turn off phone by holding power 15 seconds under a bright light
plug phone into outlet (not PC) let charge till green light comes on (not Red)
hold volume down and power for 10 seconds ( you should be in hboot)
plug phone to PC choose fastboot hit power
your now in fastboot usb
from here you reflash recovery
fastboot erase cache and reboot recovery
if your still in bootloop I'm at a loss, and seems your hboot is corrupted I think you have to return your phone to Verizon or HTC.

Well I don't know if it is truly off, I'm just assuming it is.
But yes as soon as I plug the phone into the power adapter the red led flashes on, and the htc logo appears, then the loop continues.
I'll probably take it into Verizon tomorrow and update on what happens.
Update: Welp, I gave up. I'm going to get my replacement soon and I'll be turning it into Verizon. Really it's not that bad of a loss since I just wiped the phone, only thing is I lost my screen protector and carbon skin

my pblm is i cant connect to flashtool ,i tried lot by pressing vol down and connecting usb cable , its not booting into flashmod is ther anyway to fix it ???????????:laugh::fingers-crossed:
SOLVED
My phone was restarting when i press vol down and connect usb ,was not going to flashmod
i open back cover and removed battery and connect usb cableby pressing vol down and put battery back,
and thats it it worked ,:fingers-crossed::laugh:
hello,
have a c5303 xperia sp and im trying to re-flash the stock rom using flashtool64. the phone doesnt power on but if i hold vol up/down then plug the phone into my pc via usb the respective fastboot/flash mode led colour lights up and it pops up on my computer to confirm it. when i try flash the stock rom, is gives me a error about system.sin, since then i am not able to get into flash/fastboot modes on my phone. as this has happened before (the phone not going into fastboot) im pretty sure i can get it to flash without system.sin then use fastboot to do it after.
the screen is completely blank, not even a backlight. when the usb is plugged in without a mode, it is red on the phones led, when i unplug it and try to turn it on, the red led flashes and nothing happens.
thanks in advance!
fixed it nvm
So my xperia sp (c5302) has booted into a bootloop after rooting with kingroot. I upgraded it to 4.3 and im not sure what to do because the sony companion wont recognize the phone when it is rebooting over and over again. I need help
To stop the boot looping, you can simply unplug the battery, it requires opening the phone though.
You can then boot in fastboot mode by plugging usb cable while holding volume-up key, and flash the partitions.

But the phone has that small "RESET" button which allows you to deal with such situations, doesn't it ?

Indeed it does, but I wasn't sure that triggering fastboot would work when warmbooting.
I gave i a try and it works. So the way to fastboot from bootloop is now:
1 - plug usb cable
2 - Hold volume up + reset button until leds turn blue
(if phone is in a boot loop, it might actually work by just pushing volume up during the boot)
After flashing AEX ROM phone hangs on boot screen. I can't force it to shut down, I have to wait until battery drains. Then I connect the charger, phone immediately boots up, here we go again...
I can't use newflasher.
Brick?
Use Sony Emma.
My phone is also bootlooped after i failed to flash the software.
I don't remember but maybe hold volume up and power button and the phone vibrates 3 or 4 times and after turning off.
Brick is not likely. Plug the phone into a PC, hold power button and up volume until it vibrates then hold the volume up until the blue led shows, meaning you entered fastboot mode. Then open a terminal for adb, wipe with fastboot commands and flash another rom of your choice.
I can flash zip using fastboot??
Code:
fastboot flash system rom.zip
Somehow key combo worked and I got into twrp and flashed rom
