[Q] Touchscreen stop working!how to unroot???

Hello,i need some help.
My touchscreen(and the four touch buttons: home meny back and search) stop working will i was using the phone!
Only the volume buttons work ( up and down) and the power button.
so i rebooted the phone but i cant even put the pin or unlock it...
the phone is rooted and ai using revolution hd rom.
so i started with volume down and power button(to bootloader),where i can go up and and dow to the first menu
FASTBOOT
RECOVERY
FACTORY RESET
SIMLOCK
IMAGE CRC
but when i go to RECOVERY ,the menu is touchscreen ,so unusuable for me....
i want to make the phone unroot and put the original rom to sent it back to service.
HOW can i restore it??is there a way to do it?maybe using the pc?

Yes , you can flash via fastboot , it is possible, but I don't know exactly how .

Probably you have 4ext touch. I remember reading how you can flash ROMs through adb but it might not be the most straight forward thing, so my guess is that initially you can move back to Clockwork mod and flash your ROM from there..

Well that's one of the perks of flashing a 3.xx.xxx.x ROM on 1.xx.xxx.x(4.4.2) firmware. You get to have extremely long boot up times and you won't have a proper working radio which leaves you with no wifi, data, gps, bluetooth...
Your OTA probably didn't work because of a custom recovery, not because it was rooted. Root does NOT prevent OTA updates from installing, though you might lose root access after the OTA.
If you're stuck at Boot screen hold Volume UP + Power button for 10seconds, as soon as the screen goes black press volume Down + Power button to enter into Bootloader.
Flash a custom recovery like TWRP. Go into recovery and restore a nandroid backup for your device.

first thx alot for replaying
i already got TWRP installed but the screen is stock on boot screen but still manage on the back ground to load my current rom as i'm hearing the log in sound of the rom :S
so i tried to power it off without seeing by holding the power key the power option pop up and touching random parts of the screen but i failed
i even waited for the battery to empty and factory reset the phone with no use
is these is any way even by adb to power off my phone
plzzz help

By the look of things you are booted in OS but have no screen, hence why try and hold power button in and randomly tap to shut off?
I told you already to Hold Volume UP + Power button for about 10seconds and then hold volume down + power to enter bootloader.
You can of course also just plug it in and try to reboot to bootloader using adb, if you have USB debugging enabled. adb reboot bootloader

As already said just hold power and volume up for around 12 seconds then immediately press and hold power and volume down. This will always get you into the boot loader.
However if adb is working just use the command above. Reflash the original boot.img and you should be good.

Use that to get back to the stock rom for your phone. Then after installing the right one, get the OTA

Never leave your device with an empty battery. In any circumstances.
Because you might not be able to charge it. Recover the device while you have some power on your battery.
Remember, this is a unibody device. It's not so easy to pull out the battery.

[Q] How to boot recovery with no Power button

Hi I had my power button removed because it was getting stuck. I still managed to use it and turn it on through youtube methods. But last night something happened and my phone is getting stuck at the bootup screen. Basically I can get to the download mode to use odin, but I don't know how to get into recovery mode without the power button... Is there anyway for me to boot into recovery mode without the power button? I want to reflash my custom rom.

Bricked A500M

Hello everyone.
So my phone got stuck in safe mode a while ago and the volume down button kept going off on its own when the device was on.
It never occurred to me that the reason I couldnt get out of safe mode was because my vol - button was pressed all the time when it was rebooting, making the phone boot into safe mode.
So I decided to upload a new rom, got into download mode via adb (adb reboot download) and uploaded a new firmware.
Now the phone is stuck in boot loop and I cant go into recovery or download mode, since the volume keys are not working properly and I cant boot into my phone to turn developers options on and do it via adb.
Do you guys have any idea what I should do to save this phone? Is it officially beyond repair?
Any suggestion will be very appreciated
Thanks

I would say fix the volume buttons you not going anywhere if those arent fixed.

Restore Stock Recovery?

Hi Guys, I recently had a soft brick and after recovering the software I found out that the recovery mode is gone or can't be opened "no command" it seems to me as if the stock rom is faulty, some features do not work , for example copy and paste I'm multitasking screen. Can someone help me here please?

I believe if you are trying to get into stock recovery you have to hold power and then press volume up when you see the no command screen

Sorry but it don't work for me, even if I go from fastboot into recovery don't work.

Fastboot>recovery just gets you to the "no command screen." From there is where you do the power +volume up command to get the list of recovery options.

Now it works, you have to press first power and then the volume up button. Thx, and I thought it will be gone.
Thx guy's.

Im basically in the same spot, but I while Im in this corrupted recovery - I can't go into full one. Pressing UP+POWER just restarts device to the same place.

Try flashing stock boot.img from full factory image that matches the version you are on.
