From the information in the link, it looks like its only the radio frequencies that are different. So, if you flash a mode for your model SM-T705x it is probably going to be more reliable with its connections and speed. For example, the SM-T705Y is the one that is sold in Australia and has more compatible bands for the Australian networks.

Unfortunately, mine does not have LTE at the moment and there is no option in the settings to choose LTE as the preferred connection.

i looked at the firmware for both the 705y version, the 705m version and just the 705 version..all modems same file size...not that it means the files are identical but good chance they are

however the 705y rom has param.bin which is absent in 705 and 705m not sure why...i cannot flash 705 or 705m on 705y...not even just modem.bin...do not think partitions would be any different

unable to unpack the system.img either (from any 705y, 705m or the 705...never had issue with unpacking system.img from the stock 5.0.2 of the tab s2 or 5.1.1 of the t235/t235y)

anyway sorry this is digressing from the cm12.1 discussion here
thanks (no more)

I have downloaded the stock firmware from samfirmware and have been able to extract all of them, so maybe check that the files are not corrupt. I also haven't seen the param.bin file in any of the stock firmwares.

The smasung sites have different bands listed for the UK and AU models, which probably means the radio chip is different.

AU LTE: B1(2100), B3(1800), B5(850), B7(2600), B8(900), B28(700)
http://www.samsung.com/au/consumer/mobile-phone/tablets/galaxy-tab-s/SM-T705YZWAXSA

UK LTE: B1(2100), B3(1800), B5(850), B7(2600), B8(900), B20(800)

thanks...but am running custom roms with basebands and firmware from 705 on 705Y..so am thinking they are interchangeable (some if not all)

please see my pm as do not want to clutter this board (my fault I started this side discussion no offence)

thanks

    This is a build of Cyanogenmod 12.1 for the Tab S 8.4 LTE (SM-T705). This build is based on the last copy I had of Eousphoros' device tree source prior to them being deleted. All credit therefore goes to Eousphoros for the original port. I have only fixed a couple of build errors against the latest 12.1 source.

    Please note that although I've checked that the basics are working there will probably be a few bugs. I don't think the device tree I had saved was the latest from the last of Eousphoros' builds so there may even be regressions from his last build. On the plus side the build should incorporate the security fixes in CM 12.1 since then.

    I have limited spare time and I'm fairly new to building Android, so in all likelihood I won't be able to fix any issues you have quickly. I'll post a new build from time to time if people are interested, but don't expect daily / weekly builds.

    **** Update 06/09/15 - I've made a new build which hopefully fixes the microphone during calls. Link is updated below.

    **** Update 31/08/15 - It is my experience that the mobile data is a lot more stable if you have a KitKat radio installed and don't install the Lollipop libs. This is also backed up from comments in the thread I therefore recommend that if you plan on running this Rom you flash a KitKat radio. I use version T705XXU1ANF. I've put a link to this below (use the 'CP' slot in Odin).

    Installation

    1. Flash the zip file in recovery (I used TWRP)
    2. Flash Google apps
    3. If your coming from a stock Lollipop rom, rather than Kitkat, then you need to flash the lollipop-radio.zip. (this will give you the correct libs for the Lollipop baseband to get data working.) **** See note above. It is more stable to flash the KitKat modem.

    Status Update:
    So i just wanted to let you know what i am currently working on related to klimtlte, the main goal is to get it up to date with the other Tab S's

    Lollipop Modem File:
    http://sean.sspencer10.com/modem.bin

    Currently this is what i am working on:
    1. Using the new klimt-common and exynos5420-common repos (DONE)
    2. Updated the ril, ril interface, blobs to lollipop (DONE, but will need testing)
      ^That is using chagalllte's ril because it the same as klimtlte's
    3. Switched the gpu driver from the t6xx that kitkat uses to the new lollipop midgard (Brings it inline with the other tab s's and there is a lot of improvement from it) (DONE)
    4. Fix offline charging (Tablet is turned off and plugged in) (DONE)
    5. Moved to lollipop mali drivers (WIP)
    6. Switch to Selinux Enforcing (Not started but should be easy)
    7. Official CM Support (It will happen once all of the above are done and tested)
