I have MTCD PX5 Android 6.0 device. I was updated recovery to Android 10 and installed Witson's Android 10 rom and was using it without any problem for 2-3 week. Today, suddenly my device stopped booting.
When I start my car head unit shows Android 10 logo for some time and than it goes to black screen. (Without backlight). It looks like it turns off.
I want to enter recovery mod and reinstall the rom. How can I enter recovery mod in this situation? My doesn't have a physical power button and I was able to enter recovery mod from rom by using an app called "Quick Reboot". When you select the recovery mod it simply reboot to recovery mod. Than I was able to select recovery options with external keyboard. The bad thing is as i said device can't boot in to rom.
I turned off the device by removing the battery and than connected keyboard and turned device on. While it was trying to boot I keep pressed ALT(Right side) + PrintScreen and keep pressing & releasing 'E' button but nothing happened.
How can I enter recovery mod without dissamble the unit?

Hello,
I tried to back up my ROM with Rom Manager, I selected 'Flash ClockworkMod Recovery', when program asked me to select my phone I selected Nexus One, but I have Chang Jiang Android 001, with MT6516, which is the copy of Nexus One, I continued and selected to make back up of my current ROM, after which the phone restart and I got just „ANDROID“ on my screen, I push the trackball and got the recovery menu in which I select „reboot system now“.After that I again have „ANDROID“ on screen, and can`t go anywhere from that screen, I have to remove the battery and start phone on power button.
Now I can`t go in the recovery menu any more to make back up of my ROM (neather from Rom Menager „Reboot into Recovery“, neather with trackball and power button, in both cases I just get „ANDROID“ on my screen and I have to remove the battery to start the phone on power button, and I can`t make factory reset neather, before this was possible).
When the phone is booting if I push trackball, the phone is turn on in the safe mode, but I can`t get in the recovery mode neather from there.
What can I do to get to the recovery menu again?
thanks
Hi
I have been helping a friend repair their phone after it got water damaged
THe battery has been replaced and the phone boots and can go into Android
I have since Unlocked the bootloader
Installed TWRP
Rooted it
Installed a Cusom Rom
And installed a Custom Kernel with no issue.
So In my eyes this Phone is 100% working
The Problem i am stuck with is that whenever the phone is turned on it goes straight into the Bootloader screen and the Option bit on the top (Start, Recovery, Reboot BootLoader and Power off)
Constantly scrolls through each option as though the volume key is being pressed
if i press the power button as each option appears the phone will boot into the option i have chosen
While in Android all the buttons work correctly.
Vol up and Down and the power either going to sleep or bringing up the power menu.
Any ideas would be a great help
Probably HW related, but not sure

after 3 years did u find any solution. exactly same issue happen today :crying:
Try updating to the latest bootloader. But I assume the buttons get stuck sometimes. Try smacking the buttons s a couple of times. Hope that works.
Hello, I just unlocked bootloader, flashed custom recovery (clockwork 6.0.4.8), and gained root on my HTC One S. I then attempted to install a custom ROM, (cyanogen 12.1).
After installing and telling Clockwordmod to reboot, I believe I am in a boot loop. The white HTC screen pops up and then goes to black and stays there. When I plug my phone into my computer, I get the connection and chime, and a new device appears in Device Manager called "HTC MTP Device." When I am in fastboot mode, my phone is shown as "Android ADB Interface" in device manager, so this is different. This leads me to believe that my phone is not dead or off, it is on with a blank screen. I do not believe my computer will recognize a device that is not powered on.
I have HTC Sync Manager and I have the option for it to automatically pop up when a device is connected. It pops up, but with an error saying HTC Sync Manager could not connect to your phone.
I am able to hard-reset the phone, by holding down the Power button for several seconds. However, this just repeats the process (White HTC logo screen, then black screen). I am not able to enter bootloader or recovery by holding down Volume and Power. I have tried Volume Up + Power, Volume Down + Power, and Volume Up + Volume Down + Power.
Also adb no longer recognizes my device, so I can not interact with the phone that way either.
Currently, my only idea is to allow my phone to die so I can try booting it into recovery from power off. But if there are any other ideas that would be great.
Right before I rebooted, after installing the ROMs, I got a message saying something like "Root possibly lost, do you want to fix root." I said yes, could this be part of the issue?
I am on Windows 10.

Just in case anyone stumbles on this. You can boot into the bootloader by Holding down the Power Button for several seconds, the soft buttons will blink, indicated ensuing reboot, when they stop blinking, hold Volume Down until you get to the bootloader menu. The phone does not need to be powered off for this. From there, adb/fastboot will recognize your phone, and you can factory reset if needed.
However, I figured out my problem. On older HTC models, including the HTC One S, you have to manually flash the boot.img file that is included in the zip for your ROM.
But now I've made it to the cyanogenmod boot screen and am stuck there. sigh. i've been at this literally all day.
In the end, I just flash a different rom, specially Candy5 as found here: http://forum.xda-developers.com/htc-one-s/development/rom-t2964931 and it worked.
It's possible I accidentally flashed a rom that was incompatible with my device, not sure.
EDIT: I also switched from CWM to TWRP. Not sure if that helped.

I have broken volume down button, what can i do? face the same problem
What does it mean by manually flash boot.img? After flashing a custom rom, do not reboot first but flash the boot.img via twrp which can be found in zip for the rom?
Hi,
Since my buggy Htc One M8 finally died, I bought a second-hand Nexus 5, but . . . it is buggy too :crying:
In fact, everything works well in the system, but the recovery is very capricious:
First thing I did with my brand new phone was to unlock bootloader and flash a TWRP recovery in order to install Cyanogenmod 14.1
But when I tried to boot into recovery, I had the "No command" bug, so I re-flashed the recovery, just to see. It works, TWRP shows up and I installed Cyanogenmod.
Then after verifying everything were ok with the rom, I decided to root the device, so I tried to reboot to recovery . . . buuut it just reboot to cyanogenmod, even by shuting down phone and pressing power + volume
Are all Nexus 5 so buggy or is it just mine, anyone with recovery problems here ? :crying:
PS: Sorry for grammar errors, I'm French
Did you try to enable root access under cm14.1's Developer settings?
To get into recovery with the phone powered off, hold down volume up, volume down, and power. Once the phone starts to boot release power, use volume button to highlight recovery, press power to select recovery.
Hi,
I just tried with root option checked, it seems to work better, I'll come back here if problem comes back
Thank you :good:
Hello, I have a big problem with rebooting to recovery mode. I can reboot to recovery only with application. If I turn my phone off and then hold volume up + power, then I get black screen with only one yellow Chinese text on the very top left side and then after 1 minute it's get into Chinese recovery.. My question is: how to get into custom recovery without using applications like for example "Quick boot".
I need it, because I have to install ROM again, because I did a big mistake, when I deleted one file from the "system" folder. Now my phone boot without problem, but after that everything is lagging and all applications stop working, then it automatically reboot phone..
I can't flash firmware with SP Flash Tool, because of Windows drivers. My laptop does not recognize the phone. It says: "Unknown USB device".. That's why I need to get into custom recovery for installing ROM.
Thank you in advance for help.
This helped:
With the phone powered off
Hold Volume Up + Volume Down + Power button
When phone vibrates release power button only.
As the No Comman Screen release all buttons.
Press and hold the power button and tap the Volume Up button.
Release the buttons. You must get into recovery mode.
