Comment 288 for bug 446146

For those looking for E156G firmware, I have found an unofficial site. Use at your own risk:

The (currently) last post in the thread at http://www.dc-unlocker.com/forum/showthread.php?t=308 made by artakamiryan on 2009-07-21 contains some links to this firmware. Before using, check what firmware version you currently have. One way to do this is to:

- Boot with a kernel where the modem works (ie, you -do- get a /dev/ttyUSB0
created)
 - open it with minicom
 - type the AT command "ati" <return>
 - tell us the modem response

You will get something like:

ati
Manufacturer: huawei
Model: E169
Revision: 11.314.17.00.261
IMEI: 358109021939159
+GCAP: +CGSM,+DS,+ES

or

Manufacturer: huawei
Model: E220
Revision: 11.110.05.00.00
IMEI: 358191017694576
+GCAP: +CGSM,+DS,+ES

a later E220 version is

Manufacturer: huawei
Model: E220
Revision: 11.117.09.01.56
IMEI: 358954001901277
+GCAP: +CGSM,+DS,+ES

Plese note that this is unofficial firmware provided by a third party. I have not tested it. It may in fact be for a completely different huawei model. It could even be a trojan, or contain a virus. USE AT YOUR OWN RISK.
