AT&T Novatel 2372 - Accidental flash with Bell Firmware

[cmstlist]

Yeah the advantage of the Bell firmware is it won't falsely think I'm roaming, but the disadvantage is the default APN.

I was not able to find a file with this name. If anyone is able to obtain it please PM me.

With this opportunity that I am testing between 5.26 and 5.28, both Bell (not what cmslist called hybrid, b/c I used the full flash including the ML so it is back to Bell), I have only done tests to 2 sites on speedtest.net. The result is that 5.28 is faster than 5.26 on both sites on both upload and download and ping time.

Top record is Skyway site, 6+ Mbps down, 3+ Mbps up. And traditionally (but many months I haven't tested), my home wasn't a very fast site, at least not on the MiFi 2372.

So did the change to Generic and back made any difference? I forgot to test, but it's not that big deal to me since I wanted to go back anyway.

BTW, my original flashing to Generic wasn't an accident. On one site, it was suggested that it could unlock the AT&T version so I wanted to give it a try even though mine is Bell. Turned out that it didn't work at all. I didn't get a network lock pop up, but I also couldn't get any connection. Internet diagnostic also showed very few results, meaning no comm to the modem, so it is somewhat locked out.

So that was it. Originally I wanted to pay dc-unlocker to unlock it, but after reading about people's AT&T version having difficulty on other networks despite being unlocked, I don't want to waste the money, especially it was mainly for the reason to have a better resell value but I don't want to take the blame if the buyer couldn't use it on his network.

So basically I am back to square one: locked and Bell's firmware, except it is updated to 5.28.

I restored mine back to Bell from Generic

I used a file that has both firmware and ML, I forgot where I downloaded it but it was found on one of the forums. Search for:

20418759_MUU_MiFi2372_Bell_FW5.26.2_ML3.00.57_Lock ed_Pkg.zip

It will update everything back to Bell default, and then you can optionally update it back to 5.28 if you want.

It did restore almost everything for me, except that even w/ a factory reset, it stored my own WiFi setting instead of true Bell's default WiFi. I think it got restored when I did the Generic update from Bell's firmware while having that WiFi and didn't did a factory default first, so it copied it as if it was the factory default (strange it is how they did it?).

So I am not sure how to fix this one, especially if I want to sell it later.

I haven't tested speed yet.

Only one thing good about Generic firmware is that it won't default to Bell's inet APN, just in case that's not the one you want (wink wink).

What I meant by "mutant firmware" was that I have a combination of two firmware releases now on my device. The Bell MUU appears to contain only a partial upgrade and not a full firmware - it has no files for the web UI and doesn't fix the failure to recognize Bell as a non roaming network - but it does upgrade the radio to a vastly improved version compared to the generic firmware.

Still wondering if anyone out there has a firmware file that restores the device to a complete Bell firmware including UI and everything.

I didn't understand at first, now even I have upgraded the Bell firmware after installing the Generic firmware and my speeds are much better as well as the random freeze issue has been solved.

Side note: The silver lining is, this "mutant" Bell/Generic firmware is giving me blistering speeds, with the best upstream speeds of anything I've tried:

On Bell firmware: 5673/2781, 6253/2881, 5137/1948, 6321/2989
On generic F/W: 4297/2507, 4396/2204, 4829/2645
On AT&T F/W: 4919/2463, 3249/2491, 2368/2709, 4804/2707
Mutant Gen/Bell: 6317/3262, 6304/3508, 6316/3759

Granted those tests happened over the course of a few hours and there could have been variation. But still impressive for plain old HSPA.

Would you please post the link to the Mutant / Bell firmware? Or explain what exactly you mean by that. It would be really helpful!

Okay, well here's my addendum as someone with a Bell MiFi.

I tried the generic firmware and found the speeds were worse than Bell. So then I tried the laborious procedure to flash it up to the AT&T firmware. I found the speeds were better than generic but worse than Bell. Moreover I found that both AT&T and generic firmwares detected my SIM as "roaming".

So I tried to flash back to Bell and, of course, got this "Hello World" issue. Then I reflashed generic again, which worked, and flashed Bell back on top. Now I get the generic portal, but some components are upgraded to 5.28. The problem is, it still thinks I'm "roaming". I can enable data roaming but that's risky in terms of costs if I ever get close enough to the Canada/US border.

Does anyone know if there is a *full* Bell MUU out there, whether an older version or whatever else it may be? Or alternately, does anyone know if there's a way to tweak the firmware so that my home network won't be seen as "roaming"? Because now I don't seem to have a way to get completely back to Bell stock firmware.

Thanks!

I loaded the generic firmware linked here, and I can't get past "limited or no connectivity" on modem. Any other thoughts?

[MiFiMe]

No good here. I'm still looking for the generic 5.26.2 MiFi 2372 firmware that I can try to flash the unit with. It has the Bell firmware now and I'm getting only "Hello World" for my management screens.

Anyone have a source for the generic firmware that will load on a 2372?

I have managed to accidently install the bell pkg "20419312_MUU_MSM7225_Build_5.28_pkg.zip" I notice that it changed the SSID from MiFi2372 to MiFi45E0 I tried att firmware "20419181_MUU_MSM7225_Arches.ATT_AMSS_7.11.02_Linu x_2.7.0207_2010-02-10_pkg.exe" It showed a check for both model and firmware then when I select next to flash it shows the (Unknown string) error. When I tried the Generic firmware "20418796 MUU MIFI2352 NVTL GENERIC_Pkg.exe" It says the device is not compatible for upgrade. I then click ok and it has an x next to the model and check next to the firmware.
Any help would be greatly appreciated.

May I know if the 5.28 bell firmware supports sms via web? I can only use the sms thru mobilink. I do need this feature as I use it to check my credit/balance via sms. Thanks

[wirecutter]

Not sure if this is a dumb question, but is Hello World what is on the Bell MiFi or is it just messed up because its Bell firmware on an Att device?

The one I have in my MiFi is version 7.11.02.01-11 (AT&T). I downloaded it from the Novatel Wireless website in April. I searched for it on the website last night, but I did not find it (removed?). If you need it, I have it somewhere...

Thanks for the reply !
Which AT&T firmware image would you recommend to flash ?

Thanks for your help.
