Re: ?change phones carrier id in the low level system?

Hey thanks for the reply,,,

I work for a wireless center,,, and My job is to flash phones and repair damaged ones,, I probably flash about 50 phones to cricket a month,, and have never had a roaming light either,,,
So for the longest I was under the same assumption as you,,,
But here is the pudding...
Cricket uses an older archaic prl system known as "IS-683A" its basically a simple and primitive tower listing system compared to the newer prl system that alltel uses known as "IS-683C"
what this means is that the prl system that cricket is using at this moment, will not show a roaming indicator no matter what phone it is,, unless it is actually roaming,,, at least if all my reading and assumptions are correct...
but with the roaming agreements, and data roaming agreements that sprint,alltel,verizon have together they have to use a more complex roaming list setup for interorginization billing and whatnot...

Also, This new mogul im using that is branded for qwest,, I had originally programmed for cricket, and it worked fine,, no ril on at all... and I have taken an entire qcn qpst backup of my original alltel mogul and transferred it to the one im having the problem with.. so as far as an issue with some setting that is in epst that is not correct, I just dont believe so..

also another piece of info... I super cid the phone,, and flashed the stock alltel rom/radio to this phone.. then went into qpst and loaded my qpst backup,, changed my banner to alltel, and got it all set up,, then proceeded to flash the newer radio and dcd rom onto the phone... when I got through flashing the new rom/radio, I went back into my epst and the damn nam1 was renamed back to qwest,,, and the banner was renamed back to qwest again.. so Im assuming that this follows along with what Im saying, and basically kind of proves my point...

the only way this will ever get fully answered is when we can find a way to unlock the nvm on this dang phone to allow read write access,, then I could freely search the file system for what im looking for...

if anyone else has any thoughts please chime in....
