Hello
I have 2 exactly same model of Huawei Ascend P1 LTE U9202L-1 Build120. One of them is working fine all this while. However, lately, the other device stucked at the booting logo screen and unable to boot to the main screen.
I have tried ADB and Fastboot command, and it somehow managed to get the problem set to main screen, but the "Power" and "Vol Down" buttons not working when in the recovery mode and as well the main screen. However, when I tried to boot to the fastboot mode by pressing the "Power" and "Vol Down" buttons, my pc recognized it and I could enter fastboot commands, but not in the recovery mode and main screen mode....not so sure what are the exact problems and errors....to put in simple, the "Power" and "Vol Down" buttons are not spoilt, but I do not know why they are not working when in the recovery mode and main screen mode?? Whether the problem set is semi-bricked or just software corruption??
I have read the forums about using command "fastboot flash boot boot.img", "fastboot flash recovery recovery.img" and "fastboot flash system system.img", but confusing me....and I do not want to take the risk....
I would like to know is there any faster ways to clone the rom images of the good working set, and flash it on the problem set? Any experts out there kindly assist.
Many Thanks.
Hi,
It sounds like the buttons are failing to me. Maybe it's a software issue, but unlikely. I can't find anything relevant on XDA about your issue, so you will need to ask for help here,

Good luck!
Thank you. Thread closed.

Okay so I have a bit of a situation and looking for some helpful advice, I'm not a complete novice but I seem to have gotten myself VERY stuck.
The Specifications:
Samsung Note 3 (rooted)
TWRP
Safe Strap
Rebooted recently and was in TWRP and accidentally chose "Recovery", phone now continuously Reboots into Recovery Mode in the upper left of the screen. I've tried to do the Volume Up + Power + Home button to no avail and every other combination I can think of, resulting in The same .. Reboot Recovery Option in the top left after about 10 seconds it Vibrates twice and reboots again.
I can't access TWRP, can't access Stock Recovery, Can't plug it into a PC as it just reboots over and over again after it gets power. Read a few things about Fastboot (Don't know if Note 3 Supports that, and Maybe Odin but I can't see how I'm to flash anything if it just immediatly reboots as soon as I plug it in)
HELP!

ZTE Blade C2 V809
Well I simply changed recovery-from-boot.p name to recovery-from-boot.p-bak and install-recovery.sh to install-recovery.sh-bak
Now the phone doesn't boot properly, in fact it's stuck in a boot loop:
-Starts
-Shows white ZTE logo on screen
-Restarts
Tried connecting the phone via USB cable and used fastboot devices & adb devices commands, no devices found.
Also tried pressing "power + vol down" and "power + vol up", nothing. I can't enter recovery mode or bootloader.
I need another way to get in and change the name of those specific files, or re-install the OS.
I need help finding the desired solution for this specific phone or similar brand one, or some kind of expertise who knows more about this.
There's always a way.

Hello,
Could anyone help me.
I have a Huawei Ascend P2; which from a couple of days, when I restarted it, got stuck on logo screen "Huawei Ascend", and remains since there.
I entered the recovery by pressing "Vol +, Vol-, On/Off" buttons together, and I wiped cash and performed factory rest, but it did not solve the problem.
When I tried to apply update from SD card, I got an error "failed to mount mount E: /SDcard".
I also note that I cannot turn off the phone. It will just restart and stuck again on logo screen.
I tried to get into fastboot mode by keep pressing Vol- and On/Off buttons, but it seems it did not work. Except for "Fastboot reboot", all other fastboot instructions did not work.
I do not know what do do !! Any Ideas how to solve the problem?!! Please help ?!!
Thanks in advanced.

Hello All,
This is my first post at this forum.
I've come to a point where I'm on the verge of giving up.
A few days ago my Nexus 5 entered a boot loop without me doing anything special with it - it was just in my pocket.
All see is the google logo for a few seconds , then the screen goes down for a few more, and back to the google logo.
I'm able to go into fastboot by hold down the volume down (only) button when this happens, but the boot loop happens when I choose to boot into recovery mode.
My device has an unlocked bootloader.
I have fast boot access and no ADB (ADB wait-for-device doesn't work).
Went over a tutorial from androidforums.com and flashed a completely new image using fastboot.
The entire process worked, but the phone is still at the same state.
I've read that there is and issue with the power button on these devices - so I tried all methods of knocking it against stuff without success.
I've taken it to a lab nearby and the guy there was sure it was the power button. He said he fixed about 50 of these already - after a few hours he called me up and said he had replaced the power button 3 times and he's giving up.
in short , this is the current situation :
1. Device stuck in bootloop - only google logo is seen
2. can boot into fastboot (and have fastboot access from PC) but can't boot into recovery
3. flushing a stock succeeds but won't help
4. power button seems o.k.
I am about to call this a bricked phone and look for a new one but something inside me tells me that this might still be a software issue and can be fixed.
I would be happy to know if there is a way to know what is failing in the boot sequence. or maybe load a debug application on to the device to check the HW. I've yet to find any help in that direction.
I'm a software eng. working in the cellular comm. field, so I'm up for anything that anyone has in mind.
Thanks,
Ran.

Hello, and welcome to XDA!
It does sound like a hardware issue and it could be the power button, except for one thing: wouldn't a held down power button in fastboot cause a shutdown as well? Maybe not, but I thought I'd ask that.
At any rate, better to get an opinion from someone who actually has the deivce. Please create an account (so you post in other forums) and then post in this thread (can copy and paste from here):

Hope this helps, and good luck!
Hi guys!
Is there any way to put Bay Trail based device into recovery/fastboot using USB keyboard?
My device (Chuwi V99i) has just 2 physical buttons: power and vol- (pinhole under the camera).
Current observations:
If I'll start device while vol- is pressed, then it was entering non-functioning fastboot mode i.e. device was seen by fastboot utility but any command failing instantly.
If I'll start device while vol+ on usb keyboard is pressed, then it was booting safe mode.
If I'll issue "adb reboot bootloader" then device was entering fully functioning droidboot.
If I'll issue "adb reboot recovery" then device was entering non-functioning recovery ("No Command" screen without any reaction to vol- or power button).
I was also able to reboot from droidboot/recovery using ctrl+alt+del on usb-keyboard.
If you can help me, I would really appreciate that!
