How to perform hardware and software reset - Nokia Lumia 800

Hardware reset
The hardware reset does not reset the Windows Live ID or remove any consumer data.
Because the consumer cannot remove the battery to reset the phone the phone has a special electronic circuit which cuts the phone power when the power key is pressed for 10 seconds.To perform the hardware reset press the Power key and hold it for 10 seconds. The phone screen will turn black (phone is off). Then press the Power key to turn on the phone.

[Q] P780 Lockscreen Error after KitKat Update

Hello guys,
So after downloading the official OTA Kitkat update (phone was not rooted and never was), I tried installing the Chinese Theme Center so I can install other themes. When I was playing with the lock screen and stuff, this error suddenly appeared:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
When I press OK, this screen will come up:
It says that it will enter security mode but it will just revert back to the error screen above... it's kind of stuck in a loop and I couldn't go any further since I cannot use the menu/touch buttons. The only buttons working are the power switch and volume rocker. Sadly, I can't remember if I have the 4GB or 8 GB version (I do not have the manual and the box anymore). When I try plugging in my phone to the PC, this is what it's showing:
Hope someone can help me. :crying: Thank you guys in advance!
Install a TWRP version and wipe data, cache and davilk, or full wipe option is the default first option for TWRP.
Shutdown phone (red button near sd card), than use combo (power + vol up + vol down) and go in to stock recovery. When you see green robot, tap power button once, than use vol down for navigation throw recovery, and vol up for choosing option from recovery. Choose "wipe/factory reset".

http://forum.xda-developers.com/lenovo-p780/help/help-p780-stuck-boot-screen-reason-t2864456
Read through there, there's guides that stympy gave me to root my phone, although you will have to make sure you didnt do what i did and lose my IMEI and all, Actually not even sure myself how it happened but im happy with Jelly Bean again, not keen on running Kit Kat with all its buggy ****, lag, ram hog & battery drain.

[HELP] touch stopped work [xt910]

Hello.
I have a big problem, an average day the battery of my device was discharged, and then put my phone on the charger, after charging the battery, the touch stopped working for no reason.
as shown in the video:
So I researched some things on the internet and tried to hard reset by following these steps:
----------------------------------------------------------------------------------------------------------------------------------------------------------------------
1.Power up the phone by pressing the VOL UP + VOL DOWN KEY together + PWR KEY .
2.The device will enumerate with different BOOT OPTIONS
3.Use the VOL DOWN Key to SCROLL and VOL UP Key to SELECT
4.Select Recovery
5.The device will start up with Motorola logo and power up to a little Android man logo with Exclamation mark
6.Press the VOL UP and VOL DOWN Key together at this screen
7.The device will display BLUE Text on a Black background .
8.Use the VOL DOWN Key to scroll DOWN and the PWR Key to SELECT the option desired .
9.In this case , press the VOL DOWN key till the Wipe data / factory reset is selected and press the PWR key to confirm the selection .
10.Use the VOL DOWN key again to select YES - delete all user data and press the PWR key to CONFIRM .
11.The device will then start performing the Factory Data Reset
12.Once the Formatting is complete , press the PWR key to confirm a REBOOT
13.The message rebooting is displayed on the phone.
14.The device will reboot and start the normal power up sequence
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------
And ok, hard reset successfully performed, but the touch is still not working.
Now I'm stuck in the initial boot screen of system and if I touch one of the four functions below the phone vibrates, however the system does not recognize touches on the display

[SORRY BAD ENGLISH]
Never
The phone's warranty already ended.
The unit has also been dismounted.
The Motorola in Brazil no longer accept the device.
Hi,
It sounds like hardware failure to me. But for other opinions, I will have your thread moved to your device section.
Good luck!

Recent Apps Close Button Disappeared !!

My Oneplus x was working fine . Recently i have noticed that my Recent Apps Close Button Just Disappeared and now i have to close individual app one by one by swiping. i think there is some bug with the software.
Is anyone noticed this bug also??
and also Please tell me that How to get back the recent app close button again .
Here is the Screenshot.

Mine disappeared as well
Mine too..go in safe mode..by switching off ur phone then power it on and keep volume up and down button pressed till it boots up in safe mode..there u vl find close recent apps working properly..then restart it vl come back fr few days..den repeat again..simple...
happens when Google search Updates to 6.0
Why do you want to close all Apps?
I dont know about the update. But as soon as you remove or deactivate Google search the button is gone.
Booting into Safe mode then boot normally the issue was sorted for me...
To get into safe mode follow the instructions
1.Power Down the OnePlus X
2. Hold the Power Button Until Android Starts to Boot Up
3. As Soon as Android Starts Booting Up, Let Go of the Power Button
4. Then Immediately Start Holding Both the Volume Up and Volume Down Buttons
5. Continue Holding Both Volume Buttons Until Android is Fully Booted
follow the instructions from this forum
For me a simple restart did the job and it never disappeared again atleast till now
For me both restart or save mode didn't solve the problem. But I think in my case there is no fix because I uninstalled Google search. With that the button is gone. Its a little bit strange because in my other phone I did the same but the button is still there (other phone is in CM12.1).

S7 phone problem MT6580

Rohm was installed wrong phone
Now, the phone is a new operating system, but I did touch and the camera and the flash does not work
MT680 S7 G930FD
model rord : Z6U030HA
model:gxq6580_weg_l
More than 20 system experience
All the same problems
Touch inverse
Have you tried the firmware linked in this thread?
http://forum.gsmdevelopers.com/f51/samsung-s7-sm-g930fd-clone-mt-6580-firmware-here-12699/
Once it is flashed you may need to bring back the Samsung logo by rooting the phone and editing /proc/env_logo_id with a hex editor by adding 01 to the file. Save it, then restart the phone immediately for the changes to take effect.
His experience has been an ongoing problem
I don't understand you mate. If the above mentioned ROM doesn't work, you might want to try this ROM I dumped off my phone:
http://www.4shared.com/rar/6mMhYIk5ce/Galaxy_S7_mt6580_Z6U030HA_V105.html
Is there a password
I think the problem in Lisse rom
Deleted because the calibration file
When you attempt to calibrate the Miracle error appears:
* Waiting for USB Port ...
** Set? PreLoader USB VCOM Port (COM5)?
** Please Hold "ON" to connect with the phone ...
** Waiting for USB Port ...
** Set
** Connecting AT Mode
** Test Mode, Reading Information From the Phone ...
>> Completed, but data not Found
No, the ROM isn't password-protected.
Try pressing the reset pin on top of the phone and see what happens when you connect it.
I did not understand the meaning
Try pressing the reset pin on top of the phone and see what happens when you connect it.
There is a small hole at the top of the phone which you can press with a needle. Press it, and see if it works.

Changing language to a pseudolocale and restarting bricked my XZ1

Hi,
I have already posted the full description here in the noob-friendly help thread but I thought I might get a few tips directly here.
TLDR: Developer options enabled -> Language settings -> Add language cibarA [XB] (Arabic in reverse) -> Set it as the top / main language -> Restart the phone -> Booting gets stuck in a semi-turned-on state, where system UI is not loaded (so I cant even fully unlock the phone), but the system is kind of running.
To illustrate cibarA [XB] language:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Any ideas on what I can do now to be able to get it working again? Eg. changing the locale to English somehow through an alternative way which doesnt involve ui confirmations?
Ill post this as a subquestion - I would love to try recovery mode, but no matter how I try I cannot get there.
Tried:
- holding volume up when powering on
- holding volume down when powering on
- holding both volume buttons when powering on
- rapidly pressing volume up after Sony shows up
- rapidly pressing volume down after Sony shows up
But only managed to get into Safe mode instead (dont remember which case it was).
What is the correct way to do that on XZ1?

Did you try with device off pressing volume up while you connect to PC? If I don´t remember bad from my last Sony device the connection to flash mode and fastboot mode are done either pressing volume down or volume up while you connect to the PC, a short vibration might happens and the led light turns either green or blue. Or try using the option reboot and keep pressing volume down (not power key).
