[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.

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] 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.

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!

It's hard bricked. NEVER try to flash a recovery from your phone.
I had to learn that to, I hardbricked my beloved Xperia T that way...

Thank You, i did what you said, but there was no vibrations
Last night when i plug my phone to the charger, there is no red LED light (the phone's battery level is about 80%)
today after i hold the power buttons+ volume up + volume down, the red LED light flashed for a few times
i think it's telling me the battery is fully consumed(?)
so i plugged my phone to the charger again
and there's red light!!!
what can i tell from this?

I'm pretty sure this won't work as the boot partition got damaged during his try of flashing a recovery directly from the phone.

[Q] Xperia TX hard bricked fix

I was using an app called bootbox I changed the boot screen animation. I backed up the original boot screen animation. I also did an online nandroid backup to the sd card 01, removable. I saw another boot animation I wanted to try but bootbox doesn't give the option to delete a previously downloaded boot animation. After the second boot animation the phone would go into a bootloop. So I powered it up and held down the power button. I restored it with the backup without wiping the phone. It gave me a missing boot error. Now the device is hard bricked with only the led occasionally on green when holding down the power button with it plugged into my laptop with the battery out. Then the led just sits flashing red in second intervals. It won't come on period. Is there a way to get my phone out of this hard brick status? Thanks. I have the X Rockers rom installed on it, it's rooted, with an unlocked bootloader and Android 4.3. When holding down power and volume buttons it no longer vibrates, just the LED either comes on green for 10 seconds if just the power button and blue for 10 seconds with power and volume buttons. The LED stays solid then after 10 seconds shut off and nothing. Thanks.

In your case, if flashtool or other tool doesn't work at all, you better to bring your device to SC. or upgrade your device..

It's not hardbricked. Green led = Flashmode / Blue led = Fastboot mode.
If it's flashing Red than most likely your battery is depleted. Since it doesn't seem to be a kernel problem, try charging your phone normally, or get a replacement battery, or use a universal battery charger, then you can try booting into Recovery and use ADB to delete the bootanimation.zip file that most likely is preventing the phone from booting up (or any other file, don't know what Bootbox does).
If that is too complicated for you, you can always connect it in flashmode and flash a stock rom again, since your bootloader is unlocked. Just remember the key here is to charge your battery.

How do I get into recovery or flashmode and what is adb? Bootbox simply changes the boot animation. The phone ? also doesn't vibrate. When you connect it to the laptop it makes the usb connect sound then 10 seconds later the usb disconnect sound happens. Thx A.

Z1 bricked after trying to reboot into recovery

Hello,
I wanted to flash TWRP into my Z1 C6903 so I downloaded latest TWRP img with official TWRP app and tried flashing it with RASH - Flash tool for Android. The tool stated that the flash was successful so I proceeded to reboot into recovery with the same app. The phone immediately shut down and wouldn't boot back up to neither Android or recovery. It would vibrate once when holding the power button, holding power + volume up would do nothing and phone would not be recognized by PC and even plunging it into wall would do nothing. I tried disconnecting the batter, plunging it to wall and connecting the battery back on which only made LED blink red and device still be not recognized by PC. Can someone help me how to unbrick my phone?
Thank you.

Magic keys for booting to recovery are either:
Hold Vol down and power
release Power when device vibrates, keep holding Vol down
hold Vol down until in recovery
Or:
Power on
if LED blinks press Vol up
If that shouldn't work there's fastboot (only with bootloader unlocked before) or sony flashtool. Just flash latest sony firmware and you should be fine.
There are enough threads concerning this

Then Flashtool is your friend. You have to reflash the Sony Software.
