So, the other day i have started on rooting the AFTV of a friend of mine. i rooted mine a while ago and was comfortable enough to do it for someone else.
was following the AFTVnews.com guide (very well organized site and i would say a wiki for all aftv users). the initial version on the box was 184.108.40.206. have succesfuly rooted it, installed customer recovery, busybox, bootmenu, etc, all as per the guide. have upgraded it to 220.127.116.11_514006420 updated succesfuly as well again using aftvnews.com after which have installed the busybox again. now here the strange things happen. have decided to keep upgrading it to the latest version 18.104.22.168_515030720, according to the description i could upgrade straight to this version from 22.214.171.124_514006420. followed the same upgrade procedure and after the reboot in CWM i get the Amazon Fire TV logo and doesnt do anything, left it for about 10 min - nothing. power cycled it still the coloured logo. which means somehow it got software bricked.
started to google the ways of unbrick it and followed the procedure with the USB keyboard, it worked well for me. i got in to CWM recovery and did factory reset after which reboot. no luck, still showing the coloured logo.
got back in to recovery using the same USB keyboard method and did again factory reset after which decided to install the 126.96.36.199_514006420 updated custom ROM again which was already on my sdcard.
installed successfully, rebooted and started to configure the brand new aftv box - language, network, register, etc. after all this got on home screen, system to find out that it has the stock 188.8.131.52 version (184.108.40.206_user_514006420).
tried towelroot but obviously no luck, it sais your phone is not supported. so i guess that's it, no more root for me.
where the hell i missed it? i followed every step carefully.
and why in the first place after upgrade from 220.127.116.11_514006420 to 18.104.22.168_515030720 i got bricked?
please tell me there's still a hope to root it.
