Phone was working good, few days before,I put it on charging and after fully charged it. I pulled the cable out and the power key was not working. I restarted the phone , but no luck . Soft factory reset , no luck,even after using lenovo RSA software to upgrade the firmware, no luck. Lenovo forum suggested for a hard reset, i am unable to do it without power button in recovery mode. how can it be a hardware issue?
I am unable to hard reset because power key is not working in recovery mode also.

Hello guys,
That´s not the first time i´m helped in this forum, and i need your help again. First, i´m going to put here the basic technical details of this chinese phone bought on Focal Price:
4.7 "Android 4.0.4 MTK6577 1.2GHz 3G Smartphone Android Phone com Wi-Fi, GPS, Bluetooth, Capacitive Touch Model: 9930
So, here´s the situation: Yesterday, i decided to factory reset my phone to wipe all data and i done that this way: Settings - Backup and Reset - Factory Reset. After this, my phone reboot and now the operative system does not launch. The screen lights on but doesn´t do nothing, neather the logo appears. I´ve tried to pull out the battery, full charged it and some other things and remains the same.
I´ve tried to go to Recovery mode but i don´t know how to access it in this chinese phone. I´ve tried Vol Down + Power Button, Vol Up + Power Button, Home + Power Button...doesn´t do nothing, only black light screen.
There´s any way to resolve this or enter in recovery mode with this chinese phones?
Black Screen Chinese Android Phone 9930
Hello again,
I have found that i can entered recovery mode in this phone by entering Vol UP+ Power, because i´ve tried in other chinese mobile. But in this one, by pressing this some seconds, the phone reboots again and the black screen presists. Do you know any other way to fix this?
Just curious. is it possible? Recently my volume down key suddenly stops working for no known reason. And because my phone's recovery mode is triggered by volume down+power, i cant possibly enter recovery mode because of that problem.
Volume up+power is ok, but that's factory mode. This is a pain for me because if i cant go to recovery, if i got my phone bootloop in the future, i cant fix my phone. And i found one more problem, my pc wont detect my phone too. So basically if i got my phone bootlooped there's no solution to fix it. It only charges but adb and usb connected wont show in my status bar even the drivers is installed in my pc. Seems that two problem is linked.
So is it really possible? I want to make the key combination for my phone's recovery be power button+vol up not power but.+vol down.
And i dont find factory mode useful so i will dispose it.

somebody?
Hi I need some advice please.
I have a Samsung 64GB S6 Edge, currently received an official update on Three UK Network.
I ran the update and during my phone restarted and now constantly restarts to the "Three.co.uk" screen, freezes then restarts again over and over.
I looked up how to factory reset but none of the combinations work, when I hold the volume menu and power button it brought up a "custom OS firmware" screen. I had the option to volume up for download OS or down to restart. Volume up goes to a download screen and freezes on that. Volume down sends it back to square one.
Can you advise me on my next step please? Is there a way to connect it to a PC for a forced update or reset.
Much appreciated.
Update, I allowed the phone to die. plugged it into the charger and volume, power, menu worked this time. i performed a factory reset. issue still occurs. restarts to three screen and freezes for a while until it restarts again

Use Samsung smartsync to do an emergency firmware recovery on a mac or PC.

HELP! Blue Wave 8 33GT tablet stuck in recovery mode with "No command" message
I got my Blue Wave 8 33GT (not HD+) tablet completely bricked. First of all, I know this is not really a popular device and some of you might not have a single knowledge about this one, but I hope in any way you might help me get this device working again. Thank you in advance!
Some info about this device:
Bluewave's website: Wave 8
Android OS version: 4.4 KitKat
Device processor: Rockchip-based (RK31)
What just happened? It suddenly reboots while I'm playing and gone into recovery mode with an Android and a "No command." message. Now it won't boot the system anymore whenever I reboot, it always going into this recovery mode.
It has no volume buttons, just a reset, a hard back button and power button. Holding down the power and back button goes into the recovery mode directly. Through normal boot, it flashes the Bluewave logo twice then goes into the recovery. While the reset button immediately turn the device off. There's nothing else I can think of that I can do in this case.
My laptop can recognize it as an ADB Device in recovery mode and I think I may be able to flash it via Rockchip BatchTool, but the instructions I've read states that the device should be up and with a USB debugging enabled which I am not currently able to do in recovery mode. Device is rooted and working totally fine until this happened.
Anyone got into this kind of problem and able to go through it? Please, any help is greatly appreciated.
P.S
Just let me know if there are any additional info I could give you.

Hey! Thanks for your reply and time.
I tried every combination of either of the two keys but there is no such recovery menu showing up, and I am pretty sure that this device doesn't have a built-in recovery for factory reset.
If only I could go to its download mode stuff to be able to flash the firmware...

"Long press the power button to restart the device. If restarting fails, hard reset the tablet by poking the Reset hole using a pin. " it is from FAQ
maybe this could help.
1. Press the power button to get the option menu for
Power off
Reboot
Silence phone option.
2. on that menu you have to hold down that power off option on your touch screen while also holding down the home push button on the side of your tablet.
3. This brings up a screen to reboot into safe mode..(these are the 3 steps the company does not tell you that is why no one gets it to work.
4. HIt yes for safe mode and then hold down your power and home buttons on side of tablet till the dopo Logo appears.
5. Release both buttons and hit the power button one time and then hold only the home button down till a menu option appears.
6. Use the home button to move down to factory reset and press the power button to select. Once it says complete then use the power button to select reboot.
Problem solved. Hope this will help everyone out.
The only way is to remove the battery, attached again the battery then power it on their is no hard reset on blue wave the go to settings factory reset
Hello. I have a SM-G925F which i rooted and then installed TWRP recovery by following youtube and tutorials here. Everything works fine for an hour and then the phone suddenly stop responding with a frozen screen. I tried to reset it by holding Power and Vol -. It turned off just fine however, it did not respond after attempting to turn it on. I have a feeling that i somehow messed up my firmware or whatever during twrp installation.
Notes:
1. No response when charging
2. Not powering on
3. Nothing happens when i pressed V up + power, Vol down + power... etc.
4. Does not respond to USB Jig.
Hope someone could help me out.
