T720 strange problem. - GSM-Forum

rooty · 03-09-2006, 13:06

Got T720 with dead software.
Working under XP_sp1+USB updates. Was doing like that:

Connected USB cable with 13&14 shorted.
PST found device "P2K patriot".
Made FDI reclaim. OK.
With MSS v3.5.2 uploaded:
1. flash T720_G_05.05.21R_full_flash.vfl
removed 13&14 short & powered phone on.
2. flex T720_Manufacturing_Flex_Model_GM5T0AA052.vhs
3. flex T720_EMEA_Core_SE3843AXXXX052.vhs

OK, phone is working properly. Wanted to make update... (stupid

)

With MultiFlashFlex flashed T720_G_05.08.81R_flash.shx
Phone is dead... Lights are blinking for 1sec when pressing power on button and 1sec when releasing it.
Shorted pins 13&14. Connect phone to USB, windows found "Unknown device".
PST says "The device connected to the PC is not communicating properly..."
MSS says "No devices were found on USB"
Was trying on XP_sp1 & w98SE + latest usb updates. Same result.

Connected COM cable with 13&14 shorted.
MSS found "Motorola P2k device" !!!!!!! (before was "P2k Patriot")
Made FDI reclaim. OK.
With MSS 3.5.2 uploaded flash T720_G_05.05.21R_full_flash.vfl
removed 13&14 short & powered phone on.

Phone turns on, blue display, after few secs keyboard lights comes on, after another few secs all lights off.
Pressing right arrow - display lights ON for a few secs!!!
Any other key - nothing happens!
Windows do NOT find any USB devices!!!
COM cable - "No device were found..."!!!

All i got:
Short 13&14, USB - "Unknown device", COM - "Motorola P2k device"
Testpoint, USB - "Unknown device", COM - "No device were found..."!!!

Can flash any flash with PST or MSS only via COM cable and only with pins 13&14 shorted. Can NOT flex, can NOT flash image file with PST.
