Welcome. I have a problem with system on my phone Doogee s41 pro, if i try turn on the phone, i get the message "can't load android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device." I have two options, "try again" and "factory data reset", I think that resetting the phone is enough, but i don't want to lost my files from phone, i was looking for fix this problem, and i found guide, i found out that to fix this problem i must turn on "recovery mode", use option "apply update from ADB" and apply update OTA file to my phone, only there is one problem, in internet i didn't find ota file to Doogee s41 pro, so I have a question, someone knows where i can find this file, or someone has this file?
