So here we go again.... a couple newish roms. First, the Batman rom works quite nicely. By [MENTION=5755504]star53[/MENTION] the guy who does ApocalypseX rom.

Second, the Norma Rom, which (I suspect) is the base rom for a lot of the others we're seeing... in the past, it was only partially in English and had all sorts of annoyingly Chinese (sorry, wonderful Chinese developers! We love ya!) habits, such as the clock and location being only in China and/or in Chinese.

With this version (v26) that all seems to be gone. When the "Welcome" screen first appears, uh-oh, it is in Chinsese. But after a few moments, without me interfering at all with it, the menu self-corrected to English and "United States." It also restored from my Samsung account my previous rom settings along with all my apps and desktop wallpaper and so on. Interestingly, this rom asked for my Samsung account info without asking for the Google info. Then, after I'd restored, I opened playstore and at that point it wanted my google info. It all went flawlessly as far as the install. Zero errors.

You will, however, have to flash a kernel and a datafix file along with this rom. I flashed the kernel, then datafix. I did not flash gapps, as my Samsung backup (as I said above) worked a charm to restore most of them. This rom seems very close to Batman to me - I'm wondering if Batman was based upon it. If you want things a touch more streamlined, go with Norma, but know you'll have a couple extra flashes to do. You will also have to *reflash* a copy of Magisk 5.2 (or whatever version of Magisk is current); magisk is the default rooting file used in Norma, but the necessary flashing of an N910T specific kernel means you will also have to flash root again. Thus the Magisk file. I neglected to flash that until after I'd done my install and restore; it caused no problems.

****REVISED version of above: use the brand new Flashpoint 3.1 Kernel instead. It runs a charm on this rom AND is already rooted, so no need to re-root the rom... the kernel flash does it for you as long as you download the rooted *and* ported version. If you want the unrooted ported version that's fine, too.

****HERE IS the post where you can get Norma v26 Rom (fully translated to English):

My summary / suggestion: Batman is the easy way to go. Norma requires making sure you have a kernel (Flashpoint 3.1 recommended), a datafix file, and a copy of Magisk. Yet right now, I prefer Norma very slightly over Batman.

Have fun!

An afterward of sorts... at this stage, what does one get from one of these Marshmallow roms that isn't in another? For me, I like the Norma at present because it loads quickly and seems a bit streamlined.

I sense diminishing returns on continuing to try different versions of these roms.... they are getting better but also a bit more and more like one another. Which is fine. Probably one of the more significant differences will remain the issue of wifi calling in the N4-based roms vs no wife calling in the N7, N8, and S8 ported roms. Personally, I don't see a tremendous difference in performance either way. Neither of the above roms have wifi calling.

Blessings.
