But unfortunately and out of stupidity or lack of experience or something like that, i tought i have to wipe all the data on my phone. So i checked all the checkboxes in wipe data section (System, dalvik, etc) and then wiped everything and now my phone won't turn on and stucks on the LG logo.
i can go to TWRP but the Custom rom zip file is gone, and G2 does not have any external SD card slot. if it had one i could copy the zip file on the sd and flash it in TWRP. My pc does not recognize my phone and i can not copy anything on that.
I think it's worth mentioning that i backed up my phone before that (when it was on stock rom and working) and i have the back up on my pc, but how can i copy that in my phone's internal sd card?!
Can anyone plz help me? I really dont know what to do now!
