Samsung S4 I9500


I installed new font into my Samsung S4 phone.after that it is starting and displaying only the Samsung flash and not opening.I done factory reset but same problem is there.

Try installing new Samsung ODIN OS to the device. Hopefully, this fixes the issue because otherwise, the Samsung logo loop means that you have bricked your device.

What do you do when a hard reset doesn't wipe all data from your tablet?

The recovery menu on my Lenovo Tab2 A8 is in Chinese. I can navigate to the eMMC option and select it to factory reset the device. After reset is complete, I takes me to the screen to select my language.Next screen says, This device has been reset, log in With a Google account that has been synced to this device. I don't have the Google password because it's my daughter's tablet and I set it up on the fly on Christmas morning. Google will not let us reset the password, and when I use my personal Google credentials to log in, it redirects me to the screen that says, this device has been reset... Regardless, if I have done a factory reset of the device (eMMC option), why has the device retained any information about a Google account at all? How do I truly do a factory reset to get the tablet back to its out of the box state so we can start over again, just as we did on Christmas morning?

This tablet has Lollipop or Marshmallow OS installed on it. These OS are the latest Android software with a built in theft protection like you are seeing. They want the last Google Account associated with the device so this would be whatever Google Account was setup on the device even after a hard reset. Try to bypass the Google Account if you do not know it by following the process in this YouTube Tutorial on bypassing Lenovo FRP.

How can I fix my camera in Firefly S80?

I have tried: I try rooted apps because the phone still got rooted.. I think it was caused by: I think the go launcher Z but it always heated my phone and I always need to boost it.

  • Go to Settings then Systems. Click on About Phone 5 to 10 times to unlock Developer Options. If you are on Kitkat OS then you will disable Use NuPlayer. Restart your phone and it should be back to normal.

  • Hard Reset the device which will resolve any corrupt OS or an app that is causing interference.


  • Put your phone into Recovery Mode and choose Wipe Cache Partition and then Wipe Dalvik Cache. You rooted your phone and this can leave cache that is causing interference.


  • Go to your Applications Manager and select clear cache then clear data and force stop the Camera application. This might not be enough of a solution though since your screen turns green upon rotation of an image.

Lollipop 5 signal is not available?

Lollipop 5 signal is not available

From within your Settings>Mobile Networks, check to see if the APN values match what your mobile carrier uses for APN. This happened after the update to Lollipop and many had to reconfigure their settings for Mobile Networks correctly. Selecting Choose Automatically may also solve your issue. I noticed with my phone I had to constantly choose automatically until I put my phone into Recovery Mode and Wiped Cache Partition and then Dalvik Cache.

Was the phone compatible for Metro PCS/T-Mobile? The phone would need to be unlocked and able to work on those radio frequencies for you to have service with the SIM card. If you purchased a compatible phone and the APN settings are correct then you may have a defective SIM card.

I have reset my yoga for few times, the past 2 years (data wiping) because it just won't turn on once in a while?

You are stuck in a boot loop. Hopefully, your device is not bricked. Remove the battery and try to boot up the device. If it starts the boot loop again then you will need to install new firmware.

Your electrical circuit under the screen is still wet. You need to put your phone into a bowl of rice or silica and let it sit for a minimum of 24 hours before turning on your phone again. You may have short circuited your screen components but the only way to find out is a waiting game of making sure the phone is completely dry before turning it back on.
