How return DLOAD mode?
 

Hello! I have lumia 710 which only vibrate. Flashing fine, but again only vibrate and dont turn on. Phone was repaired by writing "OSBL Qualcomm" and partition from "RM-803_RM-809_BOOTS_RAW". After restore "OSBL DLOAD" (TAB "TP services") phone dont turn on and dont flash. I try again "OSBL Qualcomm" and partition from "RM-803_RM-809_BOOTS_RAW". After this press "Restore Dload":

Dear sir:D:D:D

Did you try to write WP_OS partition with *boot.esco file from firmware for your phone?

make tp to be sure DLOAD WELL RESTORE...

Hi, Windows sometimes prevents writing on USB. But TP will write it 100% for sure.

01 seconds, means nothing was written... use TP method, it will Restore DLOAD.
