I have a rooted 51.1.40 FireOS3.
I have unlocked the bootloader. (When I enter shell, the prompt is already [email protected], and cat /proc/cmdline returns
androidboot.hardware=qcom user_debug=31 msm_rtb.filter=0x3F ehci-hcd.park=3 maxcpus=2 androidboot.emmc=true androidboot.serialno=7090030342330NUK androidboot.unlocked_kernel=true androidboot.baseband=apqI have the newest CWM (18.104.22.168.4a) and I can boot into recovery with it no problem.
I have followed steps from the OP:
pushed bueller-twrp_3.0.0-7.img to sdcard
ran dd if=/data/media/0/bueller-twrp_3.0.0-7.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
(why /data/media/0/ rather then /sdcard/? also do you still need to su to become root if you are already at [email protected]? I tried both ways to no difference.)
reboot to recovery.
and... nothing. No TWRP logo, menu, looping, just a screen full of static.
Leave it sitting for an hour, nothing changed. Pull the power, turn on again, I can return back to FireOS3 (and quickly reapplied the CWM just incase).
I've gone back and forth between CWM and TWRP a few time retrying the TWRP installation, to no change.
I'm thinking it'd be easier to just enable OTA updates, update to 5.0.5, Kingroot, and use the second instructions which worked for an earlier FireTV I needed to upgrade, but this one is the one I use and has all my SPMC config data, which I would prefer not to have to redo again, so I would like to avoid Factory Reset.
Anyone have any clue what the hell is going on? I have read through the thread and didn't spot anything that sounded anything like my problem.
