[Q] Bootloop help (cannot access fastboot/adb)

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

[Q] HTC One stuck on bootloop/no hardware keys

Hi, wondering if you guys could help me.
My HTC One is stuck on bootloop. I tried to install a GPE rom with S-ON and now it get's to the first screen of the setup and restarts itself. The problem is the volume keys are defunt therefore I can't get into recovery to flash another rom.
Is there anyway I can force the phone to boot to recovery or to hboot ? I tried to «adb reboot recovery» on boot but with no luck.
Really appriciate any help.

Put it under a light and try to longpress Power and vol-.

HI Guich, thanks for the reply.
I did try what you suggested: shined the flash from another cellphone on the One, at the top where the sensors are, and long pressed power+volume-. If I hold the buttons the phone will just restart endlessly and if I let go of the power button and hold the (defunt) volume- the phone will try to boot as standard.
What would the light do to the phone ? Is it supposed to trigger some of the sensors ?
Thanks!

His intention was to re-verify whether you were pressing the volume down key and not the volume up key. There are no hidden sensors im aware of. if nobody else can give u a solution, the only choice wud b a motherboard replacement frm HTC itself

Umh, if you longpress power and vol- it will boot?
Strange.
If you longpress under the light, theoritecally, it have to boot into the bootloader...

raghav kapur that's what I trying to avoid
Guich it boots because the volume button is broken.
I think my only chance is to, some how, force the phone to get into recovery or hboot whilst booting I just don't know how I could do that without the volume buttons.

Just another bit of information.
When I've got the phone connected to the pc, Windows tries to install an MTP device but never gets to finalize the installion because the phone reboots. If I leave the battery flat and then plug it in, with the charging animation on the phone, Windows tries to install an 'unkown device'.

Ah, sorry, my mistake.
If you've a broken vol- you don't have a lot of chance...
It's an unknown device because it don't boot.

[Q] Did I just brick my Xperia TL?

So I did a stupid thing and didn't do my homework. I flashed CM 10.2 for Xperia T (Mint) on my rooted Xperia TL but didn't unlock the bootloader first. The phone won't boot. Just a black screen. If I hold the power button, it vibrates once, but nothing comes up on the screen. No LED light indicating charging while plugged in.
Have I just destroyed the phone?

No. A custom kernel won't work on a locked bootloader, so that is essentially your problem. Just put your phone in flash mode and use flashtool to flash a stock FTF and it should boot up just fine.

Flashtool says my phone is locked and can't be updated.

Then maybe put your phone in fastboot mode and flash the kernel first... IDK, I did that once and I'm pretty sure that's how I fixed it. With 7zip you can extract the "kernel.sin" file from the FTF, and use Flashtool in Fastboot mode to flash that kernel.

Thanks. I've been trying to put it into fastboot and can't get it to work. From what I have read, I need to hold power+volDown, right? I've held power + volUp to get it to vibrate three times, then connected it with the power & volDown buttons held and nothing - no blue light for fastboot mode. I've currently got it plugged in (using the oem Sony cable) with a rubber band around the power & volDown buttons. Maybe that'll work... I dunno. The led is just staying red, and I can't see it listed as a fastboot devices by typing "fastboot devcies" when cmd is open in the correct folder in the sdk... Any ideas on how to get this done?
Thanks for your help, everyone.

It's a bit hard to understand what you're trying to do
Fastboot mode = just press vol.up, keep on pressing, connect USB, when you get a blue light release the vol. button
Flash mode = just press vol.down, keep on pressing, connect USB when Flashtool is ready to flash the FTF, when you get a green light release the vol. button
As you can see, you don't have to press the PWR button (only pwr + vol.up to reset, but you already know it).
Usually it's enough to flash a new FTF... I don't know why you get that error: maybe a wrong button combination or maybe you didn't install the drivers needed for flashtool.
If your battery is almost discharged, the fastboot method is good to flash only the kernel in order to recharge the battery and then flash an entire FTF.
I guess your device is ok.
Anyway, have you already seen this guide?

I'll give it a shot. I can't seem to get it into flash mode or fastboot mode, though. When I hold down the Volume up or volume down button and try to plug it in, the light stays red and the computer makes a "connect" sound (Windows 7 - rising tones), then multiple "disconnect" sounds (falling tones). The light stays red and the phone is not connected.
I'm downloading a stock firmware and flashtool and will report back when I've tried it some more.

I suggest removing the battery, if you have the chance.
Keep the battery removed and press and hold power and volume up buttons simultaneously. Then plug the phone to your computer and you'll enter fastboot mode.
I revived my XV with the same red led that way.
Had to remove the battery before it would work, tho.
Good luck bro!

Sorry it took so long to get to this. I've just been using my backup in the meantime.
I took the battery out and plugged it in like you suggested. Worked like a charm! I've got it flashed and running now. Thanks!

Dead phone after flashing TrinityVengance 1.3/1.4

Hi
I've flashed (including kernel) my phone (C6903) TrinityVengeanceRaptorXHD_1.3-XperiaZ1 and TrinityVengeanceRaptorXHD-LB_UB-Patch-V1.4 taken from here. Unfortunately after it was done my phone was also done.
There is no reaction on 3 buttons pressed at the same time and i cant get into flashmode or fastboot mode. Holding power button makes a single vibration that is being repeated as long as the PB is being hold.
Can anyone help me bringing it back to life? Can it be done not leaving the room or do i need some special tools or send it to guys that has these?
Regards
Wizzy

Hi
I've managed to rescue it. I'm not sure how i did that os i will put here steps that i've taken. Firstly i could not enter fastboot or flashmode by PButton + Vol UP or Vol Down button. I've opened flash tool and connected phone while holding power down button but after unpacking flash image it prompted to unplug the device and plug it again with volume down button being hold but nothing was happening.
So here are steps:
1. I've connected it to the AC and tired holding different combination of buttons ( to see if the led is working ). VIsualy no response has been noticed.
2. While flash tool was still hanged on prompted dialog i've connected the phone to the PC while holding volume down button.
3. It started flashing process.
Thansk & Regards

Anyone knows how to repair hard bricked phone?

I was flashing my phone and half way through my computer lost power. Now the phone does not start. I can't get it into fastboot, or flash mode.
Pressing 'vol up' + 'power' doesn't work either. Anyone knows how to repair a hard brick?

Does vol down + power work?
Does the charging animation show up?
Does the led emits a light?
At least you could say the support that your device turned of while applying a firmware update and that they need to give you a new device :silly:
