Tighten two volume buttons and the power button when you see a black screen and holding down the volume- and power button that would go to bootloader,in the bootloader,to select reboot.

[Q]superwipe then restart, now bricked?

I am going to install a new rom, so i superwipe all the things, then when I should choose a new rom to install, I accidentially press the "reboot system". Sign,.....now the phone is bricked? I can't go into the bootloader by pressing the vol down and power.
Even I hold the power button for ten seconds, it just power off and the power on automatically and stay at the htc white screen.
what can i do?

when i hold power for a few seconds, the virtual buttons blinks for a while, then i immediately press the vol down button, but no use, just the same whilte screen.
No, hold power for 10 seconds to force a reboot. As soon as your phone powers down, press and hold vol down, keep holding and you should enter hboot. It might take a couple of attempts to get it right.

Spot on keep trying we have all been there don't give up you will eventually get into fastboot
How do people not know the basics?? This is simple stuff
Cos they don't read. Although I remember when I first got my desire a couple of years ago, and rooted it, I was crapping myself that I might be killing it, esp as revolutionary and cwm didn't work with the erase size of 40000 I had on mine, (too late, flashed it) oops.. But that didn't stop me reading and searching, all the info is out there people, what ever you do has most likely been done a million times before. (and fixed).

Only assume your phone is bricked if you can't turn it on, or the bootloader gives you a critical error

Well mine won't turn on, battery is dead, and when I'm able to enter bootloader to check battery voltage I'm not able to charge it beyond 3543 volts or something.
Sometimes the bootloader gives weird errore like memory addresses or denied or something.
What can I do then?
The notification led blinks red sometimes, it never stays permanent red. And the sd sometimes fails as well, when I manage to enter recovery (which is not really often)

I have the same issue and cannnot get into fastboot either. I think it has to do with the fastboot option which was enabled... Is there any way to get into fastboot? Or should i give up trying...?
Press and hold the power button. Once the screen goes off press AND HOLD the volume down button and it'll boot into HBOOT. Then press power once to get into FASTBOOT (or select recovery to go into CWM)

Hi, thanks for your reply. The problem actually is I cannot get into HBOOT. I've tried about 50 times, the only thing which displays is the brilliant HTC logo screen. I notice when I hold the powerbutton the softkeys are flashing 6 times before it goes black... When it goes black i'll press and HOLD the VOL DOWN key, but still no hboot

Keep pressing power button+volume down untill it gets into bootloader.
Don't let go at any point.
Just hold them pushed TOGETHER for as long as it takes. You WILL get into bootloader or else I'm afraid something is broken...

Hold power button pressed until it will turn off.
Hold volume down while you turn on your hOV to start the bootloader and choose the recovery.
Edit: and please make sure you have flashed the right kernel before trying to boot the system

I pressed the power button for some seconds and it powered off. Power button has been unresponsive lately so I had to press it a million times before it closed. Flashed right kernel and it worked

Indeed, hOV power button is really very sensitive, sometimes you have to press two million times to make it work... That's because s2w is absolutely required for this device...

I don't think so. My HTC One V hasn't got ANY issues. Like PWR problem. I turned off s2w because it uses battery and I'm not using it
(And before I rooted it it has 1,5Ghz)

[Q] No Power Button recovery mode for factry reset

OK no power button on the motherboard
So I cannot push vol up power and home

How do you turn it on with no power button?
When it first starts to boot, immediately hold home and volume up and it should boot recovery.

OK it just vibrates and stays black and vibrates every few seconds till I'll I let go that it stays black
Try the same but volume down instead. If this works you can odin flash the stock firmware. Sounds like something may have been corrupted.

No bootloader no recovery. Stuck on htc quietly brilliant screen

I was flashing a new rom yesterday. But during flashing, the recovery 'hang'ed. I pressed the power button for a few seconds, it restarts to the htc quietly brilliant screen. Now I can't access bootloader or recovery using Power + Vol buttons. Please help

Turn off the phone completely press power button for about 10-15 sec then try with 1. volume down and then press power button no way to not go in bootloader. The hangs on the recovery can't broke your phone.

I was excited to wait a new ROM since in a couple of days ago, when I turn on my phone the HTC white screen is stuck when I attempted to install the new ROM (4.2.2). Even pressing the power button, volume buttons and bottom slides won't work.
Is there a chance to repair my phone?

LG X K500N will not boot

Hello
I've tried everything to get my LG X K500N working again.
I've replaced the battery, replaced the screen (it has badly cracked), but still the same problem.
You plug the phone in, it charges up to 5% or so and then it tries to switch on. But it never gets past the LG logo.
I've tried the reset procedures (holding down the volume and power keys) but nothing has worked.
Any suggestions?
Thanks
Greg

I'm sorry, I don't know what rooted means. The phone has been broken for nearly a year, but I have only recently replaced the battery and attempted to fix it.

Well, you'd know if it had been rooted, then.
Did you actually make it to the recovery screen or just try?

I've seen a few methods for the lg.
First
Turn off the device completely
Press and hold vol down and power (6-7 seconds)
Release the power button only when the lg logo appears.
Press the power key once
Release vol down once recovery screen is reached.
Second
With phone powered on
Press vol down and power until logo comes up
Once logo appears, release the buttons briefly, then press and hold them down again.
