Hi all, 2 days ago i bought an AT&T 9900.

The first thing that i did was an os update to: "9900jAllLang_PBr7.1.0_rel2534_PL5.1.0.652_A7.1.0. 923_DoCoMo_Japan"

The thing is that in the phone is missing the option "Network setting", that allowed me to switch to "2g" only option.

yestarday i installed all the previows versions of the os's looking for one 7.1 that give me that option:

9900jAllLang_PBr7.1.0_rel2283_PL5.1.0.593_A7.1.0.8 25
9900wapijAllLang_PBr7.1.0_rel2218_PL5.1.0.571_A7.1 .0.794

9900jAllLang_PBr7.1.0_rel998_PL5.1.0.230_A7.1.0.28 4
9900M_PBr7.1.0_rel921_PL5.1.0.230_A7.1.0.267
9900jAsia_PBr7.1.0_rel196_PL5.1.0.75_A7.1.0.74

the only one that gave me that option was the : "9900jAsia_PBr7.1.0_rel196_PL5.1.0.75_A7.1.0.7 4".

so i put the radio file of "9900jAsia_PBr7.1.0_rel196_PL5.1.0.75_A7.1.0.7 4" to the folder of "9900jAllLang_PBr7.1.0_rel2534_PL5.1.0.652_A7.1.0. 923_DoCoMo_Japan" and installed...... that gives me a 606 error, so i have to install only the "9900jAsia_PBr7.1.0_rel196_PL5.1.0.75_A7.1.0.7 4" version.

what i want to do:

i want the last os with the "network setting" option, how can i achieve that?

help! somebody?

This is not an OS issue - a long time ago, ATT removed the ability to manually switch the network. If you are in a very weak signal area, it will automatically switch to Edge (and then switch back once the signal gets better) - but you can not do it manually.

So - you might as well use one of the latest OS releases - or better yet, one of the BerryLicious hybrids.

thanks for the answer, but we are talking about:

24 hours(2g) VS 6 hours(4g) - of common use

yes, i want to use any of the last OS, but i want to use it in 2g.

There is any way to do that?

thanks.

[Don_Henry]

The only way you could do that would be to go back to a very old 7.0 release - one of the earliest ones from about 2 years ago - and I am not sure that would even work now - ATT's network may not allow it at all.

ATT is slowly decommissioning their Edge network - so they dont want traffic on it.

i don't know if you read my first post, but right now i'm using "7.1 rel 196" and i have 2g. The problem is that these release is from november-25-2011.

So, this 7.1 release:

9900jAsia_PBr7.1.0_rel196_PL5.1.0.75_A7.1.0.74

Have 2g option

How to use all the today updates with these release to use 2g, or another way to use 2g with the new releases?

PD: i'm in latin america

[Don_Henry]

So someone would have to build a hybrid based on the old 7.1 that you have - but mixed with cod files from the newer releases - and that probably wont work, since the sfi file in your 7.1 is so many series older than the current release cods.

thanks Don_Henry.

�is there another opinion?

[Don_Henry]

Unfortunately the only hybrid option you might have would be if you find an old hybrid from back when your OS was just released - I don't know if anyone made a hybrid based on your OS or not.

Unless you have experience building hybrids, I would NOT suggest you trying to build your own . . this is not an easy task,; it requires a very deep knowledge of how the various cod files (java) interact with each other (especially cods from different builds) and how the cods interact with the sfi (radio) file. If you screw something up (very likely for an inexperienced hybrid experimenter) - you could end up bricking your device totally.
