LG G2 Mini D620r: Stuck on Logo, Unresponsive USB, Factory Reset Failure, and Software Update

Suddenly the phone (in the evening my daughter wrote a text message and left it as always so that it would load, and in the morning it was dead and did not want to turn on) it stopped working. At first, he didn't want to join in at all. And now it hangs on the LG logo. Factory reset does not want to do because it also hangs on it. I tried to upload the software, but when uploading 28%, a communication error with the USB crashes. What else can you try to do?

Try to upload the new firmware again. If that's nothing, go to the site. I would check the battery voltage.

Firmware won't load. Always after a while a USB communication error crashes. Battery voltage 3.92V. Maybe some memory has been damaged (peeled off). Does it make sense to undress it (maybe some contact appeared somewhere)? Is this a typical fault with this model? What is displayed on the phone and in the program.

Try to upload the firmware with the service box, if this does not change anything, then the eMMC memory has probably been damaged.

OKAY. Thanks for the info. I don't know where you are from, but maybe you know who in Lodz you can commission it to do it well and not to waste it too much?

I don't know anyone from Lodz. You can write in the bazaar section and someone from your area will report.
