    If I flash an international rom, while my phone is sim-locked, would I get a SIM error with my H2O(AT&T) SIM?

    What about music from Nokia radio, seems I heard it will give issue if it seems it is not a USA rom.

    I believe I read somewhere that if the a rom is flashed that is a newer version, it is nearly impossible to flash an older one. Reason I asked in case I want to go back to an AT&T ROM

    IMO, You cant go back to ATT ROM.

    I've flashed my AT&T GoPhone 520 with the Australian rom, the European rom, back to the Australian rom, and then back to the AT&T rom with no issues. :)

    Is there an issue with a phone that is sim locked using a different country rom like a country variant

    Not that I'm aware of. The phone should still operate, but there could be signal issues. I've heard of LTE problems and tethering issues, but never a phone simply not operating. My AT&T locked 920 operated flawlessly on both the European and French roms....which I flashed using a thread found at WPCentral.

    The 520 is only a 4g, not lte. My main concern is the phone isn't unlocked. I would think that I would give a SIM error due to that.

    Well, my 920 worked fine flashed with the French rom. I understand your concern though. Good luck.

    I've done the same thing, including AT&T's ROM. I've flashed ROMs so many times I've lost count, probably a dozen or more.

    I don't think so, but I'm not an expert. I'd stay with 915 roms though.

    If I recall, no 520's have black yet...except I think I remember reading that it was rolling out in India. Not 100% sure though.

    I seen some do, like France, Russian Federation, Bangladesh, India. Italy is coming soon.

    Also read that if you change the folder name to the one you are using, for example: if using a 914 phone and want to use a 915, you would name the 915 folder to 914

    I am currently using 059T103 RM-915 VAR EU IL CV. The only issue is that it defaults to Hebrew. It took me a bit of trial & error to get the language switched to English at startup. The other one I've used is 059S340 RM-915 VAR APAC AU CV. IIRC it defaults to Australian English, which means I can read it at first boot.

    Also read that if you change the folder name to the one you are using, for example: if using a 914 phone and want to use a 915, you would name the 915 folder to 914
    I believe this was done on the 920 or some other Lumia, but it doesn't work on the 520. At least I couldn't get it to work.

    I was searching about debranding, and seemed one person that has a sim-locked phone flashed an international rom and after putting his at&t sim, it wanted the unlock code.

    I flashed my 920 with two different foreign roms and got no sim error. I'm with AT&T, and used my 920 for almost a year with the flashes French rom with no problems at all.

    Would it matter if that country doesn't use the same frequencies as us? Also hear the rom can effect 4g(aka 3g 1/2)

    That's great! Yeah, the only reason now to flash would be to get the Data Sense app, but that's not really worth it. Glad you got the Black update.
