Factory Reset Not Working:

[JUBERGCOL]

Good day! Here to ask help to be able to save technician expensive repairs. Yesterday I finally decided to reset to factory settings an Android Z520 4.4.2 but to my surprised the easy mode is not working. Before, too many problems encountered like pop ups, over heating, slow system, a malware... As far as I remember I force stop, disable and uninstall some apps that I don't understand. I tried a manual reset but it's in Chinese recovery. Today I still can access the internet and I noticed there's no pop ups. I request to help me out to reset and teach me only apps I need and what is important. Hoping to hear from you soon.

Those pop ups you see are from the malwares that pretend to be built-in apps.
In my opinion, I suggest flashing your phone
(I tried once and it worked.)
Don't forget to save important data first....
