Hey guys!, how are you?
I do not know how to solve this problem.. i have been trying to solve this for WEEKS :crying: , but have had no success.
I do not know what to do now.. my phone is stuck in boot loop and can't enter recovery mode because of "dead android logo" (theres nothing i can do)
There is ANOTHER problem here: when i try to flash a ROM with the LG Flash Tool it fails, getting stuck at 4% and giving an error while trying to flash the .KDZ file.. i do not know what is going on.. i mean, LG Mobile Support Tool recognizes my phone,it shows the model and the current SW version.
Can you please help me?
Thanks!!
