I've flashed dozens of different ROMs, and several different recovery apps. The worst thing to come from my tinkering was the "Custom" logo on boot. Never tripped Knox, never soft-bricked, etc... Until recently.
I was browsing around the
[INDEX]All things AT&T MK2, NB1, and NC1 (including ROMs) thread and found a few ROMs I hadn't tried before. I don't remember specifically which ROM it was, but it definitely had an Aroma installer. During the installation there was a warning that my warranty would be void. Having been warned about voiding my warranty in virtually every ROM thread, I didn't really think much of it. I did my usual flashing of the ROM, flashed the NC1 modules, then SuperSU 2.0 just in case. I've performed the same steps numerous times. Unfortunately this time when I rebooted, everything went haywire.
I got the unauthorized software message, Knox had been tripped, and I'm pretty sure I had the yellow triangle, along with everything else that comes with a semi-brick.
I don't remember all of the details because it's been a couple of weeks now, but I used Odin to get back to NB1 stock, and since then I've had trouble with sending/receiving texts, and sometimes calls. It's really strange because there is no indication that it's stopped sending or receiving. I have to reboot the phone several times per day in order to get the signal back. I know that when I originally restored to stock, I used the NB1 stock file for Odin, then flashed the NC1 update, rooted and installed ShoStock. I kept having data/mms connectivity problems, but wifi was never an issue, so I thought it may have been the NC1 modules or something. I've tried several different variations of ROMs, modules, APN settings, etc. but even with a full return to stock, I'm still losing the ability to send/receive texts at seemingly random times.
I guess my question is, could I have flashed a modem or something in Aroma that is still sticking around somehow, even after using Odin to get back to stock? One of the ROMs I flashed was for the i9505, and it seemed to run fine, the phone was identified as an i9505, but adjusting the APN settings allowed it to work properly on AT&T. IIRC, that was the ROM I was using prior to the issues (Echoe).
I'm currently on the stock NB1 ROM and haven't taken the OTA update yet because it didn't seem to help the last time. I have no idea if anyone here has any insight into why this is so sporadic, but it's driving me nuts so I'm asking for help before I toss it out the window My apologies if I've left out some info. I'll be happy to provide any details I can. I'm just at work and having to type this up in a bit of a hurry. Thanks for reading, and any suggestions you all may have.
