Chosen Solution

My phone is the BLU LIfe One X2. It prompted me to update my wireless software (sort of like the software update of the phone) and I did. It than prompted me to install the update after which it rebooted and requested for my unlock PIN. After keying in my unlock PIN, it said that’s the wrong PIN. I have tried again and again, rebooting, powering off and on again, it keeps asking for the PIN. I have 101% sure of the PIN the I am keying in but it won’t work. Now, it has given me a warning that if I input a wrong PIN 9 more times, my phone will be wiped. Does anyone have an idea of what PIN it’s talking about? I have even tried the conventional 1234 and also 0000 but none of that works. Any help would be highly appreciated.

I think I just found an answer to my own question. https://9to5google.com/2017/11/28/recent
