Hello.

What exact state of phone now?

Octopus box · 07-01-2022, 11:19

Please, download and install this test software, select K500UM, check "Operations via TestPoint" and press the "Restore preloader" button
there you have to choose from folder ... \ Data \ LMK500UM9AT-00-V30c-310-240-JAN-05-2022-ARB00 + 0_preloader.orf
