How many successes should I be waiting for? I had about 20 then I stopped the process because I thought it was just repeating the same installation 20 times.
DX150 really bricking now tried your get off loader mode trick and its not working.
If one particular method does not work for you I would suggest using a different one.
I would make sure you are using the latest tool from iBasso
TBH - it never seems to work first time for me. I always persevere and I always manage to upgrade in the end!
bear in mind, after a successful upgrade the player sometimes takes a long time to boot up
Anyway - keep trying. Dont worry, you will get there
