I flashed the Amber Australia CV rom, then updated to Cyan OTA. Lost my LTE/4G that way. It seems Cyan nukes LTE regardless of how you get it.

Slightly off-topic but probably most relevant here, does anyone still have Visual Voicemail intact?

I've stopped trying and am just going to wait and see what IFA holds next week, but I though I'd share what I've found/tried. (Note I have not gotten it to work).
Firstly, if you go into the phone and key in ##3282# (or ##DATA#) you'll get the field test mode. If you click on the ... -> Settings, Toggle ENS (reboot required) must be turned on for LTE to work. Mine was off when I first checked. I toggled this on and nothing changed, but I read that this must be on.
Second, I flashed back to the Rogers ROM found on this thread (reminder, I have US ATT 920):
http://forums.windowscentral.com/no...h-any-lumia-920-full-amber-gdr2-features.html
The flash worked, but LTE did not return in any step of this process. I then tried going back to the ATT ROM, but failed with the incorrect FUU.
What's odd to me is that the LTE radio is in the processor, so flashing to original ROM should work... Unless a register was written to that it can't undo...
Anyway, at this point, I'm just hoping a carrier unbranded 830 is available in the US that works on ATT.
Edit: Also, I put my SIM into an 820 and it only had 4G (or HSPA+ here in the US) until I updated the APN to get LTE.

Yes, I did and it does change. No major changes, I should have written it down, but it was like 1.0.202165.X or something like that vs the cyan 1.0.202184.3.

I know there are some Rogers users on here. Did you guys OTA Cyan and keep LTE?
Visual Voicemail works fine for me too.

I was able to get my LTE back working. Flashed back Rogers from my EuroDEV rom and after use Nokia Recovery Tool to flash again.

I still wonder about a ATF box or a similar product and jtag'ing it with at&t firmware if that'd restore LTE. Since it doesn't look like even with that DLL mod to nokia care suite you can flash back at&t firmware.
I know this is 920 question, but on my 1020 with Rogers ROM and Cyan, LTE works good.
Edit: This is US unlocked 1020 RM-877 which was changed to Rogers ROM.

Holy Batman,
I got LTE back too. Flashed Rogers Cyan, then did a reflash with Nokia Software Recovery Tool. Prior to the NSRT I was only getting HSPA+. NSRT doesn't like to pick up non carrier ROMs though.
So after I verified LTE on Rogers through NSRT I flashed an Australian CV ROM (I like it better than EuroDev cause it has more options) and I have LTE now.

I loaded Euro Dev and I lost LTE.
I flashed Rogers back in the device. Still no LTE.
I used nokia recover tool and the LTE is back

It's good to know that it's possible to fix. The problem for us with ATT that went to rm-821 is the Nokia Recovery Tool doesn't work and I don't know of a way to flash back to the ATT ROM. I guess I'll mess with it more this weekend.
I'm glad you all got it working though!

Is there a trick to getting the Nokia Recovery Tool to work? I'm trying to get my LTE back so I flashed back to Rogers from the French ROM and I continue to get the 0x80131500 error code. Software Recovery gets to the installation phase and fails immediately every time. Firewall and Windows Defender were turned off and it didn't make a difference.
EDIT: Oh, I guess I'm in the same boat as TheSuperShoe up there. Darn you AT&T!

Thanks for all the work everyone, I'm trying that myself now after losing LTE.

Using Nokia Software Recovery to flash again..
Phone is a Rogers 920 in Black, 059Q6W4...
Crossing fingers!
EDIT: LTE now shows up when I do a manual network scan, and it connects to LTE successfully.. Looks good!
