E155X Firmware:

DiGi Firmware:
11.608.13.01.000.B409 (14.5MB)
11.608.14.15.311.B418 (28.6MB)

HuaWei Firmware:
11.300.05.06.311 (17.3MB)
11.300.13.00.003 (23.5MB) (This is what I am currently using without problems)

more options i guess, and less the digi branding

you can reflash the firmware and play around and use the one that works best for you

There is no recommended version or firmware, each have their own pro and cons.

Different ppl may want/need different features and everybody uses the Internet differently. So best way is to play around with them and use which ever suits you best.

I've posted and uploaded all the firmwares I have for the E155X.

Before my last post, I've checked huawei site to see if there was any new version, only 1 version is currently on their site (the one I am currently using, refer to prev post), they have removed the old one.

The E155X was released Mar 2009 and was meant to be a cheaper/lesser replacement for the E159/E160.
The E159/E160 is actually better then the E155X (like how the PSP Slim was a cheaper/lesser replacement for the PSP Fat, but that's another story for another day)
The E155X can be considered an old and obsolete model, I doubt huawei will continue with future firmware updates.

E155X:
HSDPA 3.6m only, no HSUPA, means upload max 384k
(in comparison, some sierra modems are HSPA, 7.2m d 2m u)
UMTS 384k (that is as high as UMTS can go)
EDGE 240k (I once have an EDGE modem that could go up to 280k, DIGI claims their EDGE network can support up to 384k, 384k is the theoretical limit of EDGE)
GPRS up to 86k (this is the first modem I've seen that cannot support GPRS 115k)

Most of my machines are windows 2003 or windows 2005, I don't have any machines with windows 7.
My modem is now plugged in to a dedicated download machine with a non-digi sim-card.

So I guess I can't really help you on that end. Maybe asking someone else whom has a similar setup as yours?

(E155X + HuaWei Firmware + DiGiBB + Windows 7 + Facebook Photo Upload)

Ok, some clean up and updates.

for E155X, there is firmware and software

Firmware: (I don't think there is DiGi custom firmware, DiGi just uses HuaWei's firmware)
11.608.13.01.00.B409 (5.6MB)
11.608.14.15.311.B418 (6.3MB)
11.609.18.00.00.B418 (6.6MB) (This is what I am currently using without problems)

Software: (This updates the software installer in the modem's ROM, I don't remember which one is DiGi's)
UTPS11.300.05.06.311_MAC11.303.08.02.311 (14.8MB)
UTPS11.300.05.08.311_MAC11.303.08.03.311 (14.7MB)
UTPS11.300.13.00.03_MAC11.301.06.00.03 (20.4MB)
UTPS11.302.09.00.03_MAC11.301.10.00.03 (19.6MB) (This is what I am currently using without problems)

Unlocker: (Some of the updates require a Flashing Password, key in your modem's IMEI to generate the password)
v4mpire_unlocker (261KB) (This software has other functions too, claims to be able to unlock vodaphone phones, ZTE and HuaWei modems)

Files are archived in 7z, LZMA2 compression.
For WinRAR or 7-Zip, you will need at least WinRAR 3.91, 7-Zip 9.04 to extract.
(since flashing could only be done in Windows, so I guess it would be moot to put up any Mac or *nix compatible extractors)

There is no recommended version of firmware or software, each have their own pro and cons.

Different ppl may want/need different features and everybody uses the Internet differently.
So best way is to play around with them and use which ever suits you best.

Difference between DiGi and HuaWei firmware?
More options I guess, and less the DiGi branding.

You can reflash the firmware and play around and use the one that works best for you.

I'm currently using this modem with DiGi Prepaid Broadband, on Macbook 4,2 running Mac OS 10.6, mainly for file downloads. I do the flashing in Windows 2005.
So I would not be able to relate to any Vista/7/x64/Facebook problems.


Regarding Google's warning about my site:
There are many sites getting false positives from Google, unfortunately mine was (and still is) one of them.
Not to worry cause you won't be browsing the site (unless you want to), you will just be grabbing binary files from direct download links.
