Phone won't stay off and charge, stuck in bootloop

Hi, I have no power left. how do I keep my phone off so that it can charge high enough so that I can begin to use fastboot again?
I've powered down from the fastboot menu but as soon as there is enough power, it boots into the boot loop again. I need this phone to stay OFF so that it will charge.
Btw, the modaco cyanogenmod9 caused this.
Thank you
answer: fastboot erase cache
this worked for me
unplug the charger, powerdown from fastboot, then plug the charger again, it works for me... just dont touch the power button..

[Q] HTC One X can't acces recovery (NO BATTERY)

Dear XDAs,
I've got a problem with my HOX. After I installed the ViperX rom, I can't acces the recovery and my battery is completely empty. So I downloaded a small script
Code:
@echo off
:start
fastboot getvar battery-voltage
fastboot reboot-bootloader
ping /n 6 localhost >nul
goto start
but i won't work. The message I get when I start it is "waiting for device" (since hours). Please help me.

P.S.: A small excuse for any typos or errors in this text but my main language is german.
Are you trying to charge from wall charger or usb ?. Better to use wall charger. try powering down completely and plug into wall charger and leave for at least 3 hours

Thanks I'll try to charge with the official wall charger :victory:

[Q] Arc s with no os and battery dead not booting

Hi guys, I'm here because I'm deseperate. My arc s won't boot if i press the power button or if I connect it to pc . It has no os because i format the system folder while I was trying to flash a rom, and the battery is surely dead. I cannot enter neither in fastboot nor in flashmode. Is there any way to charge the phone so that I can flash any firmware? Or should I buy another battery?

It will go in Fast boot mode Just press Menu key(on my neo v its on right side of home button) and see if blue led turn on in your arc.
if your device still not entering on fastboot mode and you want to charge your mobile battery then find any compatible universal charger for your device
I guess by saying "universal charger" what fenix meant was a spare battery charger which, charges batteries while unattached from the phone itself... or he/she probably was referring to something else.
anyway, the spare battery charger that I know looks like this:
http://www.ebay.com.au/itm/BA750-Ba...Arc-XPERIA-Arc-LT15i-Xperia-X12-/170822357636
or you can just search through google for it using the keywords "spare battery charger LT15i anzu".
good luck!

dead battery , can't boot rom or recovery

Hello,
I am running OMNIRom 4.4.x on my device ( x9006 ).
I was low on battery (14%) so i connected it to the charger and it seemed to charge, but after a minute
the phone crashed and i couldn't boot into recovery or the normal rom.
I know that charging while device is off doesn't work,
my workaround was to boot into recovery, charge the phone there for a while and then boot the rom and charge normally. This obviously doesn't work, when you can't boot into recovery.
I can only boot into fastboot, but fastboot is really weird. Normally you can read fastboot in the middle of the display, but this time there was a white rectangle and not "fastboot".
The phone is recognized on my computer and i can run fastboot commands.
I tried to flash twrp 2.8.3.0, but still can't boot into recovery.
Is there a possibility to charge the phone in fastboot? I don't have an external charger.

remove the battery, plug the phone to the wall charger and after that put the battery in. IT worked for me
Thanks, i will try this next time.
Luckily my friend had an external charger,
so i charged it there and then normally.

Charging only after reboot

I have strange problem with charging. When device is running and I plug a cable then it's not charging. But if I power in or reboot with plugged charger then everything is ok until I remove and plug in cable again. Then I must reboot device...
Also when phone is off and I plug a cable then it's charging ok.
I tried wipe all, restore system, even install new ROM from scratch. Always the same... Any idea?
