If you have access to a computer or laptop you can download the Sony PC Companion Software from the Sony website & use it to restore the firmware of on your Sony Xperia J.... Another way to reset the firmware is doing a factory reset via the recovery menu. Execute the appropriate button combination to boot the phone into recovery mode & then choose "wipe/factory reset" option. ***This method will completely erase all your files on the phone so make sure you've backed up anything important prior to resetting it***

Back up anything on the tablet that's important or you dont want to lose & save it to a SD Card or computer for safe keeping & give the tablet a good old fashioned Factory Reset!

The LG's system firmware is corrupted and you'll need to completely re-install the original LG system firmware to restore the phone to working order again...

It sounds to me like the screen you're referring too is the "Download Mode" screen.... To get the phone out of that mode & start up normally again you need to do the following to restart the phone: Press and hold the "Vol Down"+"Power" Buttons at the same time for about 10-15 seconds until you see the phone shut down then release the buttons. Your phone will reboot & start up like normal

Unfortunately they don't share those parts... iPhone 4 & 4S have interchangeable LCD's, but not the iPhone 5 & 5C, they have different sized board connectors. Not sure about the camera though, but the display's definitely aren't interchangeable

The Micromax AQ5001 does not have the options or settings in the phone to allow you to move your apps from the internal storage to a external SD card unfortunately. It is still possible for you to move your apps to SD by installing an app from Google Play which does this for you... however, it would require your phone to be Rooted. Once rooted, then you would need to install an app like "Link2SD" or similar and you're done!

Hi there, It's a somewhat tricky procedure to get it into its recovery menu to reset it, may take a few tries to get it right but here's how... WARNING THIS WILL ERASE ALL DATA, PICTURES, AND SETTINGS! 1.)Power tablet off 2.)Press and hold power + volume up 3.)When the "Insignia" appears, release power button but continue holding "vol up" 4.)A small list of words appear in top left corner 5.)Release volume up button 6.) Use (volume down) to select "recovery Kernel", then press (volume up). 7.) Wait a second, and a robot will appear. 8. )When the robot appears, press both the "Vol Up + Vol Down" buttons together... this may take several attempts to get it but eventually you will get a list of commands, one of which is "Wipe data/Factory Reset". Highlight it using the "Vol Down" and then "Power" to select it. 9.) Then you'll see a confirmation screen, so again "Vol Down" to move, and "Power" to select. 10.) now the system will reboot, this will take a couple minutes

Did you try to root the device and something happened during the rooting process? Or was it a failed software update? In any case, I would say the software has become corrupted causing the boot up failure you're experiencing. You could try performing a factory reset from the recovery menu to see if it fixes your boot issue. Doing a factory reset will completely delete everything stored on the phone , so hopefully you've backed that stuff up on a memory card where it's safe and sound! If that doesn't fix the problem then you'll probably need to reinstall the Samsung firmware. Here's how you get into the recovery menu... Keys Combination to Enter Recovery Mode: Step 1 – Turn OFF your Galaxy S Duos. Step 2 – Switch ON the phone while pressing and holding Volume Down + Volume Up + Home + Power buttons together. Once in the recovery menu, use the "Volume Down" button and select "wipe data/factory reset" then press "Power" button to select. Next, scroll to the "Yes wipe all data/factory reset" or something similar

Chromebook wasn't designed to run on any windows OS, its a Chromebook! Chromebook's run chrome OS which is Linux, not windows. That being said, Linux is capable of running some windows software via their WINE emulator but its very limited and not really compatible . Only certain Chromebooks can possibly run windows OS but there's a good chance of bricking your Chromebook permanently since your going to be messing with the firmware, hacking it I guess you could say... much in the same way a android phone needs to be rooted via a exploit & have its bootloader unlocked in order to enable the flashing of custom ROMS... Now if you want to still give it a shot at your own risk then have a look at this page to get a better understanding of whats involved and the dangers associated with attempting the whole procedure. http://www.digitaltrends.com/computing/h...-to-install-windows-chromebook/

12345 ---> This is the default security code on all Nokia phones before a user changes it. Try this first when asked for the code. If that doesn't work try the codes below, they may help you solve your problem but not guaranteed! Insert the following codes from the phones dial pad: *#7780# ---> (reset to factory settings) *#2640# ---> (Displays phone security code in use) ?? *#7370# ---> (Deep Reset: Removes everything and puts the phone right back to factory settings) *#7328748263373738# ---> (Resets security code) I've not tested this one myself so i'm unsure if it will do anything!
