MTK6582 ROM port: I've tried everything! Need help checking specs. - Android Q&A, Help & Troubleshooting

Hi, I've been working on replacing the OS on my MTK6582 for many days over the last 3 weeks. I've followed several very helpful guides but I simply cannot get an alternative ROM to successfully boot. The original stock ROM is buggy and won't even connect my SIM to the network!
I've found this guide [Guide]How To Port & Modify Roms For Mediatek[Everything] by @digyvijaykumar123 to be the most helpful but I don't think the OP is active any more and the Q&A page is stale. I've tried posting in the Noob Friendly thread with no response.
Honestly, at this stage I'll try anything! So please give me the benefit of your experience and knowledge!
The phone is an unbranded clone. It's called "Lenovo A808T" but it's obviously not a Lenovo and A808T seems to be completely misleading - not even equivalent to the popular clone "A808T Golden Warrior" clone.
Here's the MTK Droid Tool info:
Hardware : MT6582 (MT6595 is Fake!)
Model : LENOVO
Build number : ALPS.KK1.MP1.V2.11
Build date UTC : 20140914-111625
Android v : 4.4.2
Baseband v: MOLY.WR8.W1315.MD.WG.MP.V35, 2014/07/17 10:42
Kernel v : 3.4.67 ([email protected]) (gcc version 4.7 (GCC) ) #1 SMP Mon Oct 20 17:21:08 CST 2014
Uboot build v : -----
LCD Driver IC : 0-sh1282_dsi
I've tried porting 7 ROMs but the most successful (i.e. have installed in CWM but have not booted) have been the following:
Inew V3 Huawei Emui 3 port KK,
Lenovo S860 VibeUI 2.0,
Honor 3C Hol-T00/U10 MIUI,
Lenovo S850 VibeUI 2.0.
All ROMS have been based on the 4.4.2 Android version, the MTK6582 chip and most on the same resolution. However they either boot loop or hang on the "welcome" logo.
Some questions I have are:
MTK Droid Tools detects the phone as a MTK 6582, is this detection 100% unmistakably correct?
Will using a ROM with the same build number "ALPS.KK1.MP1.V2.11" make a boot more likely? All other ROMs using this same build number seem to be for the MTK6592 which makes me suspicious!
MTK Droid Tools says the OS is 4.4.2, is this also 100% correct (or is this easily changeable in the build.prop or some other file)? If it could be misleading, how can I check and confirm the real Android version?
I'll find another ROM and keep trying but at this stage it's like banging my head against the wall. I've invested literally days of time on this so I'd hate to give up now. Any advice will be gratefully followed!
