Default [Q] N7105T 4.1 - problems flashing custom ROMs

Have a N7105T on stock 4.1 + root + Philz Touch CWM, and am having trouble flash ROM's other than HashCheck (4.1).

Have tried PACMAN all-in-one (4.3) and Omni (4.4) as both 'N7100' and 't0lte' variants, with similar results for both.

The N7100 variants install but mobile not recognised.

The t0lte variants refuse to install. From what I can tell, it is failing to assert it is on a N7105T. EDIT: The Omni 4.4 ROM reports that I am 't03g'.

My process in each of these cases has been to perfom the installs from recovery: wipe/factory reset (clean for ROM), install zip, install google apps, wipe cache, wipe dalvik, boot to rom. I have an IMEI backup using the QPST tool.

I'm not touching modems at this stage. Also haven't run a stock 4.3 rom yet.

Others are obviously on 4.3/4.4 custom ROM's. I've been scouring xda for help but can't find the relevant advice. What am I doing wrong?

EDIT: after seeing the Omni assert failure reporting 't03g' it now appears 't03g' matches the N7100, but I definitely have a N7105T. Refer: link autoroot.chainfire.eu and teamw.in/project/twrp2/115 where t03g is N7100 variant. As the t0lte ROM variants are aborting due to failing their asserts to identify my phone, is this a ROM build problem? Can't ask this in the dev section because despite being a 3 year member, haven't needed to post before. Can anyone suggest what info I could get from my phone that may be used by the ROM's to identify my phone?
