T500 WWAN and 1804 despite BIOS patch

[ThinkRob]

Hi,

I've been trying, unsuccessfully, to get a Dell-badged F3507g working in my new T500. I've applied the 3.09 BIOS update courtesy of Zender, but the 1804 error persists.

Does anyone with a T500 have any tips for getting 3rd-party WWAN working? I haven't tried taping pin 20 since I was under the impression that the BIOS patch obviated the need for that. Can anyone confirm whether that's the case? (Normally I'd try it, but I'm loathe to open my machine more than necessary due to the risks, albeit small ones, involved in the process.)

Thanks!
-Rob

please download the white namelist from here

http://2.12.tel.115cdn.com:8080/pickdow ... WW_BMD.rar

and update your rom to lenovo authority 3.12

and using the winplash.exe flash the T500.rom (just downloaded),

notice, if any problem occured, please give up.

this is only including whitelist no slic 2.1 included.

Thanks for the response, darkrain, but I'm not really sure what you're proposing as a solution.

I did notice that you mentioned a Windows program though, which makes it a bit of a non-starter as I neither use nor have Windows on my ThinkPad.

Any other suggestions?

Bump.

Anyone else gotten a Dell Mini 5530 card working in a T500?

The Lenovo branded Ericsson F3507g is much more expensive than Dell branded F3507g.
Is it possible to use Dell branded F3507g in X200, T400 or must one do Bios hack etc?

Please accept my apologies for not posting a follow-up.

Yes, the current Zender BIOS mod works fine. And yes, you can use a Dell-branded WWAN card just fine.

May I ask what's the "current" mod version that worked? I found only http://forum.thinkpads.com/viewtopic.ph ... er#p609922, which holds a 3.09 BIOS version, which didn't seem to work for you earlier.

Thanks.

3.09 does work. Turns out my flash was bad -- it completed successfully, but didn't seem to actually flash the BIOS. Repeating it did the trick.
