How to flash Lenovo s820?

Question

Android

Hello. Please tell me how to fix the problem with the phone. The phone is remote, I have no access to it at the moment. From what was described, the problem is as follows. The last few days the phone just turned off and did not turn on for a long time - for several hours. Today, after we got the SIM card, the following message flies out: "encryption failed ... the data on your phone is no longer available due to the fact that the encryption was interrupted ...".
1. Will it be enough to just reflash?
2. How to reflash without access to the phone system? After all, in order to download a new firmware, you need to give permission to download files via USB directly in the phone itself, and as mentioned above, it does not start.
3. What firmware is better to download? There is a forum with firmwarelenovo-forums.ru/files/category/24-%D0%BF%D1%80%D0...
Thanks in advance
