You can repeat firmware writing/unlocking for same device with 0 credits. It will not require credits for same device.

Hi can you help me out, I have the same Telenor Serbia (220-01) router, but I can not find drivers to see the COM port.
I need driver for USB\VID_12D1&PID_1442&REV_0102&MI_00

Found on some obscure web site: http://devid.glenn.ru/209426 , checked with virus total and it was OK and now I see COM port for this modem

I did step one, flashed with 21.180.99.03.00, but i stuck with step 2... How do I unlock device?

The device isE5577Cs-321, also locked to Telenor Serbia...
After firmware 21.180.99.03.00 write, display shows FTM with Huawei logo

Just to add, my DC unlocker no longer recognize my e5577C modem, i get message "modem not found !"

Where in device manager you see modem now? Flashing done without errors?

[dtodorovic13]

flashing done without any problem, but after flashing, device manager didn't recognize device. Dc unlocker also didn't recognize modem.
Today I installed mobile partner from huawei and that did the trick, modem driver instaled and dc unlocker found my modem.
After modem was found, I did unlocking with dc unlocker and flashed modem with new firmware, basically the steps 2 and 3 ronnin wrote.

Thanks for all the help

Forgot to mention... modem unlocked, ...

Yes, credits for flashing same device are taken only once.

[URODY]
