check your original post, i gave you the keys to the city
As I'm sure everyone is aware, I am a noob on this forum and still in between a novice and intermediate at flashing custom ROMs onto my phone. That being said, I currently have a Sprint SIII that has been flashed to Boost Mobile. Why I switched is irrelevant, so, my main question and concern is if I flash a new ROM on my phone, will I loose my service with Boost? I have searched around and found some similar problems or issues of some ideas of what one can do if there were issues after flashing, but nothing that clearly answers my specific question. I used the search function in a few places around the site, and not just in the SIII forum, but if I overlooked something that does answer my question I apologize. At any rate, I hate being on the stock ROM because I feel so limited, even when rooted. The ROM I want to use is an AOSP ROM that I used before I flashed my phone. It worked very well and I really liked it. This was even after I bricked my phone by flashing an international version of a ROM onto it (total noob mistake) and had to get someone to use a JTAG on it. By the way, if anyone needs to unbrick their phone and the usual methods don't work, let me know and I'll post the info of where to find the guy that fixed mine for $35. If that's not allowed in the forum, I can definitely send a PM. So, to finish this book and sum it up again, if I flash the custom ROM on my phone again, will I loose my Boost Mobile service? If so, can someone tell me or at least point me in the direction of where to look to fix whatever problems I might have? I haven't done the flashing yet because I am not looking forward to without phone service again. I just went about a week without service after I bricked my phone. Lastly, if it matters I did not do the switch to Boost myself, so if I need to record my MSL code or something like that, that I heard mentioned on the other places I looked, I currently don't know how to find that. But I am capable of rooting my phone and installing apps that can supply that info. Thanks in advance!
Thank you very much. So I will be using TWRP recovery, what do I have to backup first before I flash my ROM? Do I have to do a Nandroid backup or something, or is there some specific data that I should find and backup. Furthermore, if it helps, I have Titanium Backup as well as ROM Toolbox, PRO version of each. Would either 1 of them be helpful?
Your best off just doing Nandroid backup and not using Titanium or other such programs for backup. You can sometimes flash to a new rom and then restore data or programs using Titanium and then cause bugs or problems with your new rom. You only use Nandroid backup if your flash to a new rom really goes wrong and then you can use it to restore to a stable working version of whatever you had on your phone previously. As long as you keep the original Nandroid of your stable working system then you can try flashing to a new rom and then advanced restore Data to try to get all your programs and settings back that way but again just like Titanium backup you could cause instabilities or problems with your new rom but same chance that everything could be fine and you get a new rom with all your old apps and settings If something doesn't work you can always go back and restore everything back and try a new rom flash and then know not to restore data.
