kt3 basic, poor brick without diags, u-boot only, how to send backup files?

[NiLuJe]

@3ldn1k: You missed a few things. We've since confirmed that most (all?) KT3 actually do ship with a new diags which does feature ADB.

[3ldn1k]

wow! really? i miss this thing about adb on a kindle, maybe, because a few months i dont read this forum (from april till now) so, it is a good news, congratulations.

Hello, I have a bricked KT3 with broken diags partition too, but I did't have a full backup before. I wonder if I can get a diags(mmcblk0p2) backup from you. I will be really appreciated if so.

Could you please sent a backup-file to me? I have a broken KT3 But I have no nither giags_kernal nor backup files .
