CM12 on a (UB) SGP621 (LTE, 16GB) version? topic

Hi there folks, and sorry if this has already been discussed elsewhere. I hope somebody will be kind enough to point me in the right direction.

I currently have an LTE version of Z3TC and have already followed lowtraxx's tutorial for preserving TA, then made a pre-rooted ROM using Cubic07's method.
So, now I have a fully functional, rooted, stock firmware and I'm very happy with it, but I really wanted to try out CM12 on my tablet and that's where troubles started.

First, when I tried to flash the Advanced Stock Kernel from this thread: http://forum.xda-developers.com/z3-t...-root-t2959720
I couldn't flash CM12 because TWRP complained about my device being scorpion_windy (SGP611 I guess, the Wi-Fi/Non-LTE version). Then I somehow managed to flash Dual-locked-recovery from this thread: http://forum.xda-developers.com/z3-t...ry-qa-t3014211 and finally I've got CM12 chugging along on my tablet, but couldn't get it to mount the /system partition as read-write.

So maybe there would be somebody who could write a more comprehensive manual for getting CM12 on our devices, or simply start a discussion about it to counter the common pitfalls?

PS. Will AptX still work after upgrading to CM12? I really hope so, as it's practically the only 'closed' feature that I need on this tablet - the sound delivered by my new SBH80 headset in AptX mode is terrific!

[Q] 16gb or 32gb + LTE? topic

Hi

I hope the QA is the correct forum for this.

I had a 32 gb nexus 7 2013 that got stolen from my home. The boss of the perpetrator is paying me, so i am going to buy one of the 2 available nvidia shield tablets.

I have never owned a tablet with LTE, but i remember that the nexus tablets with that feature had their factory images released later, for example.

Is there any reason in favor of the 16gb one with no celular radio in regards of updates, factory images, rooting?

I don't care about custom roms when the stock one has important features, but if the nvidia features are just apps, i might care about them too.

ps: i did read about this tablet, but i am buying it mostly because of it's size and prize in my country, and i like stock android. My nexus 7 2013 was stock, albeit a custom kernel cause i wanted to delve into F2FS

ps2: 16gb should be enough for my needs, considering it supports sd cards, where i can store my media, but playing it safe is always a good idea, and had my old tablet had a celular radio, i could have tracked it beyond the moment it left my home's wifi, and since it was password protected, it can never be connected to another wifi without factory reseting it.
