Zenzr posted a topic in Galaxy S4 Guides/TutorialsThis guide is for those who do not want to do full odin updates, but still want the newer radios to play with without all of the worry about new software to deal with. If you have issues, please post here and I will happily help you. I am assuming you have Odin working on a PC, if you don't let me know and I'll try to help you as well. First off, you'll need the Modem.bin file. This is your radio that you will be flashing. MDL Radio: http://upload.teamuscellular.com/5HT MF5 Radio: http://upload.teamuscellular.com/5HU MJA Radio: http://upload.teamuscellular.com/36z MK2 Radio: http://upload.teamuscellular.com/5HS NAE Radio: http://upload.teamuscellular.com/5EX ND1 Radio: http://upload.teamuscellular.com/36y NF6 Radio: http://upload.teamuscellular.com/384 NK1 Radio: http://upload.teamuscellular.com/9hy Here is a link to Download Odin. http://forum.xda-developers.com/showthread.php?t=2189539 1.) Turn off your phone. It has to be powered down completely, do not boot into download mode directly from your ROM. 2.) Boot into download mode (Vol Down + Power). 3.) Plug into your phone to your PC. 4.) Load your Modem file into the PHONE slot in Odin. Not PDA. It will be named differently if you are using Odin 3.9+ I believe. 5.) Assuming Odin sees your phone, click start. It should only take a few seconds for it to run. 6.) Let it reboot. Click settings, About Phone, and your Baseband will now be whatever modem you flashed! Enjoy! Let me know if you have questions I'd be happy to help troubleshoot. Stock files can be found here: http://teamuscellular.com/Forum/topic/4447-stock-files/
Is there any way to edit the parameters on a SIM card? Mine got corrupted and is missing the following info; Phone number, Subscriber ID, Sm country ISO, SIM Operator, Network Country ISO, Network Operator, Network Operator Name, Network Type. I have all this information saved elseware so is it possible to just program it back in? The wierd thing is that I still get 3G, not sure about 4G (not in my area). In anything but the stock ROM the connection square in the quick settings menu just has 3G with 3 bars, I get data but no phone or MMS, and the Carrier spot says empty. I flashed my phone's modem to the one for 4.3+ to get the new networking stuff but this didn't solve the problem, I tried the card in another phone and it told me the same thing. SIM card doesn't connect regardless of kernel or ROM. I'm currently using the SCH-R970.
I am first of all upset at the terrible performance of my Galaxy S III's reception. Specifically it's radio. This is well documented in another post here and by the fact there is a rumor of Samsung replacing the phones. In the mean time I have been using my S III on CDMA only while at work and other areas where the data signal wasn't constant between CDMA and LTE. Band aid to a problem that should have been solved before releasing the phone. Today I started reading up on Samsung radio's because I have thought all along this is a hardware issue. The following articles are what I found and in my humble opinion, further my hypothesis. Back in December 2011, Samsung released the Galaxy Nexus under the guise of a Google phone. It was released on both GSM (AT&T, T-Mobile) and CDMA (Verizon/Sprint). The CDMA version was plagued with reception issues similar to the S III is having right now. I first found this article that explains in great detail why the radio in the Galaxy Nexus is inferior on CMDA. Read this, its a great explanation: http://mobilecentral...on_GSM_and_CDMA Then I found a forum post about how this specific radio plus Verizon's CDMA infrastructure equals problems. http://androidforums...zon-radios.html Not a objective post, but insightful none the less. Fast forward to now, We have S III users with no issues and others with major issues. My completely unscientific research and purely speculative opinion is: Samsung used the VIA Telecom CBP7.1 CDMA2000 baseband modem is some of the S III's and these are phones having problems. (Plausible but not probable). The baseband modem in the S III is another VIA Telecom and this one is having similar problems to the Galaxy Nexus on Verizon. (More likely). I could be completely off base here because Samsung could have used a Qualcomm modem in the SCH-R530 US Cellular S III. But I still think there are issues on the backend that CDMA providers like US Cellular and Verizon need to work out on switching signals between 3G and 4G between tower and phone. I apologize for the rambling, but I am disgruntled at the performance of my S III, US Ceullar's LTE spectrum, and CDMA in general.
