Kdesi som sa docital, ze mam tzv. čistý bootcore a nezapísané info v OTP.
Fullflash zalohu mi xflasher bez problemov urobil, patchovat som zatial neskusal.
Zatial neviem odpoved na otazky:
1. Je bezpecne skusat patchovat?
2. Mam pouzit funkciu "freeze" na zapisanie IMEI do OTP, alebo mam nechat nezapisane? Ak ano, ak je presny postup, aby som si nezablokoval telefon?

Vopred dik za odpovede :-)
