[Q] Booting problem

hi. I encountered a problem on my phone that doesn't boot properly.
When i tried to switch on my phone it showed at first the welcome msg "Samsung S4 mini gt-i9192" then after that, a pitch black screen, could not properly boot. But i learn that it does not turns off after the screen turns all black, i have to press the power button first to turn off the phone.
This problem started when i installed an app with some compatibility problems.
I wanted to root my phone hoping that can solve the problem, but then again a problem occurred when i tried to connect my phone to my laptop. It fails to install MTP usb device to my computer. I tried connecting it again provided that samsung kies was installed but again failed to connect my phone. Therefore i cant root my phone because i cant copy the files needed to root to my phone sd card.
I tried reinstalling kies, installing mtp drivers but nothing happened. I tried also restoring the previous boot image, restoring factory settings using recovery mode. But then problem still exist.
And fyi my phone can't mount any external sd card using recovery mode. And i think it was not in a debugging mode.
Phone: samsung s4 mini gt-i9192
firmware: i dont know
So basically, the problem is:
my phone wont boot,
i cant connect it to my pc
and i cant root it.
How should i root or even flash my phone when i cant connect to my computer? Do you have any idea on how to solve this problem? Any solutions or suggestions would be much appreciated. tnx.

Have you tried putting the phone in download mode (Volume Down + Home + Power) and then connecting it your p,c , if not give this a shot it should pick up the drivers , once done , take out the usb cable hold the power the button to shut down and boot up .
since you have not mentioned your OS am assuming it is windows , try taking out Kies via some software like revo uninstaller which will remove all directories plus all registry entires then reinstall it if you really need it.

dial *#0808# from your cell this would take you in usb settings, tick both mtp+adb , reboot , if they art already ticked uncheck them and check them again.

yah, thats what im thinking. i just brought this here hoping to solve this problem without going to a shop. thanks anyway.
aac. To me put your phone in download mode then use moborobo(a windows software) . Just open it and it will install the driver. If it dies not work then use adb installer . Remember you should have only any one of the software at one tim means either moborobo or kies or adb installer

btw have you tried to boot the phone in safe mode ?? if it boots in safe mode it is still fixable without going to service center. power down , power up+ tap the menu button 3 or 4 times at THE same time to boot into safe mode if it boots into safe mode that means the hardware and OS is fine if it does not well then your out of luck.

[Q] Galaxy Tab 3 7.0 Won't go into recovery mode

I have in my possession a Galaxy Tab 3 7.0 inch, that will not go into recovery or download mode. When you hold the power and volume up button it starts regularly, despite the fact I have several other Galaxy Tab 3 7.0 inch tablets that do go into recovery. I cannot get it to go into download mode either, so I'm stuck as what to do. I have confirmed that the volume keys do indeed work, I can change the volume of music with them after the system has started.
My goal is to do a factory reset on the device, is there some trick I can do via USB to put it into recovery? Or maybe do a reset over USB?
Any help is greatly appreciated.
Yeah it can via adb shell and you know you should hkld home button top?

concerning button combination to recovery/download modes
apparently the home key is not needed on p5210 at least, only power &vol+ =recovery
power & vol- = download mode
edit; tab 3 7.0 does need 3 button combo
check root by opening terminal and typing su
if return with [userid]# then you have root
type whoami , should return uid0 or command: not found , means no busybox
at root prompt # , type reboot, or reboot recovery
okay so [edit] my thought is your home button may be boned or sticky/dirty
a side question, i need to know commands for following if they exist
i need to know what the BOOTLOADER outputs by way of log if there is one
i need another way to get mmcblk names as the cat /proc/dev device by name
isn't present on my tab.
i do apologize for unrelated questions, but couldn't see starting new thread for that
i don't mind pm's so please feel free. thanks for reading
:good:
For download mode
Keep pressing
Power + volume down + home key until it vibrates
And for recovery
Power + volume up + home key until it vibrates

solution::; bro just open your device cover remove bettry. then try home buttone power button and volume up butto.. press these three button at same time for 10 second u will get recovery mode .
The best way to get this done is to use Android Debug Bridge (adb).
Get Android SDK on your PC, plug in your Android Device, and run adb reboot recovery in ADB shell.
That command restarts an Android device in recovery mode.
