Hi everyone! Again with the same problem. I did a full wipe using Fiio Tool back to 1.2.3 and everything worked fine (no loading problems) then I installed 3.3 kernel and again: stuck in Welcome screen. What happen? Every time I install the kernel I will get the player corrupted? What are the steps to delete the corrupted file that every time gets me stuck in welcome screen? I’ve tried many things and nothing...maybe my device can’t use the custom kernel anymore.
I have not happened upon (myself) the 1.2.3 img to use with the firmware upgrade tool. I have always used the 1.2.1 img if I needed a fresh start.
But do you perform a subsequent factory data reset with erase of internal storage afterwards?
There should be little reason why your player can't use custom kernel even in 1416 MHz variant.
My steps are always:
FW upgrade tool -> 1.2.1 OFW
Factory data reset w/ internal storage wipe
Technical support application upgrade w/ local 1.2.X .zip
sometimes another courtesy factory data reset
Android Tool to add TWRP
TWRP flash superSU, wipe dalvik/cache, advanced- fix permissions, reboot
TWRP flash kernel 2.8 (fixes any bugs with init.d scripts)
Get optimizations prompt
TWRP flash kernel 3.32
Wait for reboot prompt,
Reboot,
Get optimizations prompt.
Go back to TWRP and delete whatever system applications/musicFX backups AROMA installer created, as well as pre-install apk for es file explorer found in system partition.
