I have an iPhone 6 with 64 GB of storage, just yesterday I recorded a lot of videos and it stopped automatically due to full storage. When trying to send photos using LINE, the app keeps on crashing so I tried to delete videos from Photos app. The videos disappear but suddenly return back to Photos, then I opened recently deleted folder to clear it first before attempting to delete other videos, but when I opened recently deleted folder, all of its contents are white and they won't disappear even after I select delete all. I thought maybe a quick restart will fix it but I was wrong, my iPhone was stuck in bootloop for hours. I tried updating through iTunes but keep getting Error 1100 three times. Finally I tried 3uTools, tried iTunes Flash 3 times but still getting Error 1100, then tried Easy Flash but the connection was interrupted so I need to force restart my iPhone twice and restart the 3uTools program, didn't continue using Easy Flash so I don't know what will happen, I instead try iTunes Flash once more and it succeed, my iPhone turned on with all data still intact.
