debranding
persistent (= irreversible) method
Just download and run the following dashboard update (allthough designed for the E1550 it's fully compatible with the E1750):
http://www.huaweidevice.com/worldwide/downLoadDetail.do?method=downloadFile&flag=1&fileName=32158&attachmentName=E1550-Client+Software+WINMACB300D00SP01C03+(UTPS11.300.13.00.03_MAC11.301.06.00.03)+(For+WINXP%262K%26Vista+%26MAC)+(05019427).zip


volatile (= reversible) method

If you don't want to change the flashmemory of your E1750 permanently, you may also use the following method, by which the flashmemory will just be disabled and instead a microSD-card will be used to store an unbranded generic version of Mobile Partner. In the end you'll have the same result like with the persistent method, but it will be reversible (see below "rebranding"):

  1. Insert a microSD-card into your E1750 and format it.

  2. Download this modified version of Mobile Partner (originally UTPS11.300.05.00.03) - [mirror 1] [mirror 2] [mirror 3] [mirror 4] [mirror 5]

  3. Extract the downloaded rar file into the root of the microSD card.

  4. Run the AT-command: AT^U2DIAG=256 (how to run AT-commands) - this will disable the flashmemory, which will be replaced by the microSD-card, so after plugging in the modem from now on only the microSD-card will show up and the setup of the modified "Mobile Partner" will be run automatically.
    Sometimes AT-commands will result in an "ERROR" - in this case keep reentering the AT-command until "OK" is being returned.
  5. Now you need to safely remove the flashmemory component of your 3G modem:
    • Click the "safely remove hardware" icon in the taskbar:
      Windows XP: safely remove hardwareHuawei E1762 - 3G modem wiki

    • Eject the flashmemory, which should appear as "CD-Drive (X:) Mobile Partner" (or similar designation)
  6. Finally unplug and replug the 3G modem. Now only the microSD-card should appear as new drive and the modded version of Mobile Partner should be run automatically. Of course the microSD-card must remain in your E1750 in order to have installation files for Mobile Partner at hand.


rebranding (not testet)

In order to get back the flashmemory follow these steps:

  1. Remove the microSD-card or format it.

  2. Run the AT-command: AT^U2DIAG=268 (how to run AT-commands) - this will reenable the flashmemory, which was replaced by the microSD-card.
    Sometimes AT-commands will result in an "ERROR" - in this case keep reentering the AT-command until "OK" is being returned.
  3. Now you need to safely remove the flashmemory component of your 3G modem:
    • Click the "safely remove hardware" icon in the taskbar:
      Windows XP: safely remove hardwareHuawei E1762 - 3G modem wiki

    • Eject the flashmemory, which should appear as "Huawei 3G" (or similar designation)
  4. Finally unplug and replug the 3G modem. Now the original flashmemory and, if a microSD-card is present, also the microSD-drive will appear as drives.

Googling 1752, shows its a dual band UMTS, not tri. 1756 is shown as Triband.

Does this support ?, on the net i saw ext antenna for this, but i dont see any ext port crc9 on the device.
As per the 3rd image as above, next MA550 chip, there looks some kinda copper port, is that antenna port ?

or is there any url, who has tried connecting an ext antenna on 1750/1752.

At least one person has reported this modem (huawei e1752) to be able to receive and make calls (http://dc-unlocker.com/forum/showthread.php?p=12252&posted=1#post12252).
I have enabled voice feature (dissabled by default) and I can make calls but can't receive them (caller gets "subscriber not available" message).
I wonder if this depends on whether the operator, firmware or dashboard. My firmware version is the same as the one used by that person who has it working fine. My dashboard is updated and with voice (11.302.09.01.539, plugins version 1.01)
So...anyone had this problem and knows how to solve it?
