I bought a kindle fire first gen but after the unboxing.. i saw my kf have last one version of "amazon-android" 10.2.4 and with this version i can't root ora change bootloader/recovery/rom.. and also kindle fire UTILITY (xda) doesn't work... is there a possibility to put an older version than 10.2.4 into the kf so i can root it? SORRY for my bad english.. im italian. Thanks for reading.
