Snag its baseband... see if it will work on s3... have odin ready just in case.
Ya wanna hear what's really weird? If I use CTMOD or the working version of AOKP or CM9 for my Marquee, the signal goes to almost nothing. It's only with the stock based ROMs that I get good reception with that phone. Thankfully the Marquee ROM that Chevanlol360 and I worked on for the Boost version (Megatron) is based off the stock ROM and it's get's almost a full signal when running it.
Bloodawn even has made the basebands flashable through CWM or TWRP. I may decide to pull one of those from his zips. That will be the last thing I try though if I'm not happy with the results from the other testing I have planned.
Here's what I'm thinking bro. I think that this S3 is doing the same thing my Marquee does. It gets decent signal with the stock Boost ROM that came with the phone.
I was doing some reading over on XDA last night and quite a few people have reported their service getting worse after flashing the Sprint ROMs. Sooooo, just out of curiosity, I'm gonna test a few of the modems available to us from Sprint. I flashed LJ7 late last night and I'm gonna try it for a day or 2 then do the same for a few of the others.
I had originally tried a few of those modems but it was just a quick flash, check and see if I saw a difference, and then moved on to another. That's not the correct way to try them from what I now understand. I've read that people have noticed better results from testing those modems by giving them a few days. Some of them said they thought the phone may have needed the time to adjust itself to the new modem. Whether that's true or not, I don't know. I'm at least gonna try it that way though.
I did a good bit of reading last night and some say one thing while others swear by another. In reality, the only sure fire way for me to find out what works for me is to test these methods myself.
Wasn't it you who said he was using the LJ7 modem? I remember someone posting that they were getting decent reception with it. That's why I chose to test it 1st. Right now I'm sitting on 3 bars.
I also plan on reverting completely back to my stock Boost backup and see what affect, if any, it has on my phone. For some reason I have a feeling I'm going to end up getting a stronger signal just running the stock set up. When I 1st got this phone, before flashing any ROMs or anything, I had one heck of a signal out here.
Anyways, you know me..... I'll definitely keep you guys posted on my findings.
Probably won't be testing any new ROMs and adding them to the thread for a bit. I want to make all of these reception/modem tests while on the same ROM. Definitely better to test that way. Especially if it's true that the phone and modem may need time to adjust/calibrate to the my phone, area, and towers.
