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..

I have come into my possession a Kindle Fire 1st generation. When I got it, the youngster said it was “hacked for the Amazon App Store”… and the battery was dead. I traded an older laptop for it. I put it on a charger for a day or so and left it. It would boot to the “Stock” logo for several seconds, then the backlight would go slightly brighter and it would shut off.
I started reading up about some of the power-on issues around the web. I found most of my answers on “xda-developers.com” for my TF101 so I gravitated here.
Here is what I’ve done so far:
1. Acquired a factory cable... SO useful.
2. Flashed FFF v1.4a and TWRP v2.4.4.0
3. Played around with fastboot.exe commands -update, flash, erase, getvar, reboot, help
4. Flashed a stock bootloader and recovery… trying to get it to charge.
5. Disassembled and tested battery voltage… 4.10VDC on a 3.7V battery. That sounds good to me.
6. Tried the firekit boot from Live-USB. Won’t stay powered on.
Right now, I’ve flashed the FFF 1.4a and TWRP v2.5. What happens is, in normal boot, the fire boots to the FFF logo (White &Blue) goes to “Booting” and the power switch LED gets slightly brighter, then the backlight goes slightly brighter and the whole thing shuts off. If I push power to go to recovery, the fire shows “Booting.” Then, the power switch goes orange, then it goes off, then the whole thing shuts down. I cannot do any ADB commands because the Fire will not stay powered on in that mode. The factory cable keeps it powered on, but I’m stuck with fastboot.exe commands in that mode.
I do not have a stock charger. I’ve been using my charger from my TF101 and a cable from my phone or the factory cable. I’ve been futzing around with this thing for a few weeks and would like some input. I haven’t found an identical issue so I’ve decided to create a thread.
I’m wondering if I have a bad gate on the memory chip… I’ve seen desktops and laptops shut down with bad memory in the past. I’m reasonably savvy with a command prompt and not afraid to crack a box.
Hold the power button until the device shuts off completely. Plug it in to your USB cable power source (not the factory cable), and let it power on automatically. Immediately after it starts to power on, hold the power button to shut it off again. Let it charge in this state for a few hours and try to boot into recovery again.

Thank you Soupmagnet. I've done this and let it sit for a weekend... sorry I didn't mention it before. With a voltage reading of 4.1, I think I have a full charge (by the way, it doesn't drop over a day or so). You can be assured that I've tried most everything before posting. Please be gentle if I didn't state it previously
One of my issues is I can't get to anything on the fire itself. Even with the factory cable, is shuts off if I choose to continue... hold the power button and choose recovery, normal, reset boot mode. Is it supposed to be able to go to recovery when the factory cable is connected? It only stays powered if I leave it at the FFF logo.

What command did you use to install TWRP?

Fastboot -i 0x1949 flash recovery c:\KFU\recovery\twrp.img.
This is after I renamed the v2.4.4.0 file to old_twrp.img and downloaded the v2.5 that I found last Friday. Previously, i'd used the KFU. Last week I played around with flashing different bootloader and recovery to see if I could get it past the FFF or stock. At this point it's a challenge to get it to go further than FFF.

Use fastboot to flash this to your system partition and see if you can boot normally.... http://d-h.st/NzN
Perhaps it is hardware, not software
Just had a very similar issue. Turned out to be stupid simple.
Use spudgers to gently take the back off the case (a small flathead screwdriver should do the trick). then check the connection between the battery and the motherboard. In my case, my daughter had dropped it enough times that the connection was not all the way out but not enough in. This caused the exact behavior you are describing. Took me 2 minutes to fuss with once I got motivated.

So I'm trying to install the new Lollipop preview, but everytime I boot to fastboot and plug the device into my Mac it freezes. It's rooted and unlocked, does that make a difference? If I go to fastboot without being plugged in it functions as expected, letting me move up/down, but as soon as I plug it in it doesn't respond to anything and I have to hold power to force restart.
EDIT: Fixed. I think it was the cable. I used a different cable when I got home and it works fine now.
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.
I get new HTC m8ql_ul, first i unlock bootloader succes. Then flash twrp-recovery-2.8.6.0-m8s-qlul also with no problem. In TWRP i flash new rom, but gets problems. eg after start didnt see sim card. And after plug to comp, and set data transer not charge pc didn see my phone, also in twrp cant see or fastboot also. I tryed fiew times flash difrent roms. but also same thing : when install via aroma, never get 100% but eg stuck at 30% after fiew sec show 100% and info about succesed flash but stack on HTC logo.
But now when i off phone pressing ~10s power, afrer this push power + V+ and nothing, no bootloader no flashboot no reaction, when press only power phone start display big battery icon and thats its, must ~10 power to off icon, even not plugged to pc.
What can i do? Flashboot didnt see phone. Pliss
for me plugging my HTC one m8s into an wall outlet, and pressing the volume down and power button gets it to boot into recovery, im no expert at this by any means, but hopefully this helps!
My volume and power key is destroyed, when the battery dropped to 0%, I cannot boot it up because no key to press, please help me to find a rom to auto boot on charge

If that happens, connect your cable into pc, PRESS and HOLD vol up button and then connect your phone, the phone will boot up into recovery mode, you can restart there.
Same as vol down button, but instead recovery mode it will boot into fastboot mode, you need fastboot installed in your pc, and use this command; fastboot reboot
Idk you have to use usb pc connection though, you can give it try with wall charging.

Ah, my bad, I didn't see, I though it only power button.
So what you want is disable offline charger, so you can't charge when the device turn off it'll boot instead and the thing is its kernel related.
But you can try disable offline charging using fastboot mode, fastboot oem off-mode-charge 0
Idk if still work or not
EDIT: I tried by myself, it didn't work
