[Android Q&A, Help & Troubleshooting] matth2106:
Hi everyone, forgive me for my bad english...in this day i'm freaking out because it happend an unexpected thing. 4 days ago in the evening i looked that was an error message about whatsapp in the home screen, then i open the app and appeared that chat list got problem and to solve that i need to restore backup or i get lost chat. The device was connected to wifi house, but i had whatsapp backup on my phone. I searched on internet and on official whatsapp page i red it was possible as an error. To solve that need to restore last backup. I done it but while the loading has started, after a few minutes the devices shut down and reboot. It's arrived to the logo of the ROM and then shut down again and reboot. i undestand it was a bootloop. Two years ago i install android kitkat because the device can't received android 4.4 and i don't want stay with 4.3. Everything fine. After an year the device goes in the bootloop, but i don't know why, so i decided to format data ad restore kitkat again. Before that i can transfered some data because i saw that if device was connected on the pc it not gone in bootloop. This year another problem but more little. The device sometimes reboots so i do a backup with titanium backup and then wipe everything including internal storage because on the boot after flashing the ROM the device can't memorized anything. In that occasion i don't reboot the device because i wiped internal storage so everything. Connected usb-device to the phone, copy gapps, rom, twrp and super su. Reboot and the smartphone was reborn. Whit titanium backup i restored all data. This time the thing is very very different and more difficult. In my opinion probably i could download a virus with whatsapp, usually it is connected to a link into a message sended by a contact in whatsapp, or happened something during the restore of backup of whatsapp. The device goes constantly in bootloop but i can entry in recovery mode. i noted that can't see the gapps, rom e supersu file in the sdcard like the other times. They are only in the data\media\0 folder. Everythime i try to copy something not in the sdcard, it goes on an error about a netstat file i found in the data\system\netstats folder. It's a file short, different by the others. I red that netstat files can be deleted but this file can't be deleted by using twrp>advanced mode>file manager>name of the file>delete. Before try to do another format data or again a total format of internal storage like the other time, i need to know if this procedure can resolve the problem. This time i was not prepared so the last backup is about six months ago. In this months i inserted new contacts and this time i don't sincronized my contact list with my google account like the other times because i couldn't image to be in this situation. I try to delete the file using adb but my phone is not recognized so the serial number doesn't appear. List of deviced attached is empty. In this case i can't activate the developer funcstions by tipping in the device information into the phone because it goes in bootloop. On the pc i have usb-drivers, but now into the phone there's android 4.4 not 4.3 like the first time i do the procedure to unlock the device. So with adb don't see serial number but the pc just see the device like google nexus adb interface. Copying file as contact or dialer or data about apps because are all in the data folder, appears an always an error about netstat and the red failed written. just copy from sdcard folder to usb external device this not happen, what can i do?

I done a nandroid backup because i know that with titanium backup i can restore data i want to restore, but also in this case could appear the same message error about netstat file? All data are been copied on the external usb deviced and then on the pc, but i don't know if the problem will be present again. so if i try to restore data with titanium backup and the problem reappers i don't know what to do.

Here we are some information about my phone. I hope someone in this fantasctic and big community about android developers can help me to solve this very big problem. if i thinking about i've done i feel so stupid because probably i could avoid this problem.

i forget to say also i tried to fix permission, wipe davilk cache and cache, copy log to sd (to see if there's another error but i don't know how to do). After all of this passages, everytime appears the same error.
