I have problem ... more than 5 days... i try to make some EDL Auth Xiaomi flash in many models (Mi9se / Mi9 / Redmi Note 7 / K20 / Mi9T) and UFI return same error when try to connect server to get authorization. I'm from Brazil, already try all the times and in the best time (9:30pm India Time) and never work... always return same error. Spend money in dongle and spend more money to buy credits to make this EDL Mi Auth Services here... Need Support and help to fix this. Please !!!!!
Always receive same error:
ERROR: Only nop and sig tag can be recevied before authentication.
[SERVER] Service unavailable, server query response failed !
