[zcache]

Hi,

I have 2 module that restricted band MO0401 and MO0402. so I tries it with unlocker client to enable band. it say enable band ok... and I shut off laptop unplug wall power source. wait a second moment and open it up on again and I check it still restrict band..

again.. I did with downgrade FW to V1.4.6.0Hd but result still same before. module can't to enable all band

step I did
1. by this post http://www.dc-unlocker.com/forum/sho...8&postcount=12

2. FW upgrade V2.9.5.0 http://support.ts.fujitsu.com/Downlo...610D6&Info=FTS

Yes, it may be that these bands that you try are not supported by manufacture.
Dc-unlocker can only enable bands that are supported by manufacturer.

I tried to enable all band on GTM382w that was restricted only UMTS2100 to UMTS2100/1900/850 this is frequency that supported by original manufacturer (http://www.embeddedworks.net/_ewdown...213/GTM382.pdf)

I didn't did it over than paper sheet. by your advertize dc-unlocker client can enable all band by original manufacturer support. so it should can I believe that..

compare with other module that not restrict, module also same code.

Then maybe need to change firmware version. Sorry, do not know what may be wrong more.

I have Option GMT382:

Product Name: GlobeTrotter Connect
Product Version: 3.1.0.1107
Drivers version: 5.0.26.0
Serial number: PR299CE3PW
FW version: 2.20.0.0Hd (Date: Jul 8 2010, Time: 09:00:21)
Device version: 2.1

It work fine in the 3G network - Utel in the Ukraine, but not found and do not lock to the 2G GPRS/EDGE networks. It said me:

Unable to complete the operation: x84000003

I ran the DC-Unlocker V1.00.0975, added the one credit and try to Unlock all band. Not resolved it..

Then i did shutdown the notebook, removed the battery, waited 10 sec, inserted the battery, ran Win7, ran the DC-Unlocker again, unlocked and do not reboot the notebook.

I see - i can select from UMTS/HSDPA to the EDGE/GPRS and backward!!
Super. I did not change the firmware version. And i have the newest version: 2.20.0.0Hd (Date: Jul 8 2010, Time: 09:00:21)

But after reboot i see again the error: Unable to complete the operation: x84000003 after i try to change the band...

Why?
Maybe i need to downgrade the firmware version to the GTM382_fw_v1.4.6.0Hd.zip or to the FTS_OptionFirmwareVersionFW2950forOptionGTM3_2950_ 1038094.ZIP or 3G_Acer_Option_GTM382E_FirmwareTool_v2.8.1.0.zip?

I have added the screenshots, thank you.

3G:



2G after unlock, but not after reboot:

If i run the DC-Unlocker after reboot, i can again change the 3G-to-2G band. But to the next reboot.

This is error afer change the band from 3G to 2G:



And the unloock screen of the DC-Unlocker:

Again tested. After shutdown, reboot or the sleep mode - the 2G band are not working.
If i run the DC-Unlocker and do not reboot or shutdown or sleep the notebook, then 2G bang is working. And i can change between 2G or 3G.

I think what the modem have the newest FW version, and your DC-Unlocker can not write the changes to the EPROM. Maybe i need the downgrade of the FW version to the:
OptionFirmwareVersionFW2950forOptionGTM3_2950_ 1038094
or
Option_GTM382E_FirmwareTool_v2.8.1.0
or
GTM382_fw_v1.4.6.0Hd
?

After the discussion on the live chat: i shall try the software 83_GTConnect_AllCards_EN_2.3.0.630 instead of the original Option software 137_Hokku_Option_Standard_Modules_3.1d0-1107.32167_41601P and the Acer software 3G_Option_5.0.20.0_Vistax64Vistax86XPx86_A

I have try this software 83_GTConnect_AllCards_EN_2.3.0.630, but the including drivers did not installed for my Option GMT382 modem... With the other drivers version this software can not find the device...

Maybe i shall try to downgrade the firmware...
