After uploading the phone restarted...
then I flash flie to unlock: GT540_GT540f_GT540GO_V20_FOR_UNLOCK.crc
and still the same:/

And another thing ... how to put the phone in emergency mode??
Because the display is a download mode, vigis sees as the emergency mode...This is normal?

benguetcowboy1 · 03-24-2011, 02:35

- for GT540 - press and keep pressed "Volume down" and connect USB cable to phone,
on LCD must appear "Emergency mode"

try flashing first with original flasher to normalize phone then unlock in normal mode ..vygis will auto swith mode to download during unlock process

i just got one yesterday gonna try it later on today if i get a chance...

DOUHAL · 03-25-2011, 12:49

For Emergency Mode sequance see this post :

Quick HELP Entering to Emergency Mode Combinations {UPDATABLE}..

- For flashing use LGQ_1_67SC or higher software version.

- Phones with V20 firmware can't be downgraded to V10a version.If you will write to phone V20 firmware,later
you won't can write to phone flash with V10 firmware.
