All MT65xx android phones are plagued by the same problem, No Custom ROMs & there are just too many models out there... 
DEVs that are developing custom rom for it are only a handful. If you have the same model as these DEV then you are very lucky indeed to get cwmr & custom roms from them. But what about those hundreds if not thousands of MT65xx out there ?
No worries, you can port any Custom ROMs to your device quite easily using Master Shifu dsixda's Android Kitchen....
Links for that is below my signature...
Even though they are for MT6573, some of them are still relevant...
Many have successfully ported numerous of MT6573/ 75/ 77 custom/ stock ROMs out of it....
Full Credits & Special Thanks to Master Shifu dsixda for making such a Super Easy to use & Fabulous Android Kitchen...
Below is what i found out when porting ROM, you may need to patch the following below from your stock ROM for it to work...
modem.img - SIM1/ 2 not working
libcameracustom.so - Camera no auto-focus
mtk_stp_wmt - Wi-Fi/ Bluetooth can't switch on
Generic.kl - Home key doesn't work
So here is my quick & easy patching tut for porting Lewa OS to MT6577 based Ulefone Star N9776. Everything works except for FM radio...
Added on May 06 2013 - Hmm, it seems many never follow the whole thread & begin porting using this tut...
Read this post here & here first, rest of the procedure is same... Thanks to fellow xda members that has contributed to this thread... 
Another one here for Porting Master Shifu bgcngm's V970 Custom ROM to Lenovo A789...
Everything is working on this one...
Recently, i get just too many PMs regarding ROM porting & i don't know everything... :laugh:
So i'm starting this thread & hopefully to get more involvement from fellow xda members to share their experiences as what are the other files needs to be patched to get it fully working...
Pls include...
1. Name of your device
2. ROM that you ported from
3. What are the things that is not working initially
4. What are the file names & location to patch it
Cheers...

Added on Mar 31, 2013 - Patching MT6628 ROM to work on MT6620 & vice-versa
Thanks to kumar abhishek for letting me know that it is possible to patch MT6628 to MT6620, i found out Star N9770 which is from the same company as my Star N9776, some Chinese manage to patch it, everything works & this info found out by s_bd on china-iphone so i use that as base to find out which file is the culprit...
Below is what i found out, need only these few files (patch from stock to ported ROM) & everything works...
This is of course minimum patching because its from the same manufacturer...
FMradio
system/etc/firmware/mt6620_patch_e3_hdr.bin
system/etc/firmware/mt6620_patch_e6_hdr.bin-> If yours is MT6628, you'll need to patch all mt6628_fm_*_*.bin too
system/etc/firmware/WMT.CFG-> This is the antenna cfg, without this, FMradio cannot receive clearly
system/lib/modules/mtk_fm_drv.ko
system/lib/libfmcust.so
Wi-Fi & BT
system/lib/modules/mtk_stp_wmt.ko
system/lib/modules/mtk_wmt_wifi.ko -> After patching, both works & can be individually switch on/ off
system/lib/libbluetooth_mtk.so
system/lib/libbluetoothem_mtk.so -> MTK Engineering will show MT6628 if not patch...
system/etc/firmware -> if yours is MT6628, you'll need to patch all WIFI_RAM_CODE_* too
GPS
system/xbin/libmnlp -> This culprit file is the GPS. Took me the longest time to find out
Found out recent for porting Lenovo s890 (MT6628 to my MT6620), some apps at system/vendor/operator/ is blocking GPS so just delete all apps & use MTK Engineering mode to confirmed it... :fingers-crossed:
build.prop
fmradio.driver.chip=1 -> if yours is MT6628 then change it to 3
mediatek.wlan.chip=MT6620 -> if yours is MT6628 then change last digit to 8
mediatek.wlan.module.postfix=_mt6620 -> if yours is MT6628 then change last digit to 8
updater-script
symlink("wlan_mt6620.ko", "/system/lib/modules/wlan.ko"); -> if yours is MT6628 then change last digit to 8
Happy Porting...

If your Lewa cam is not working in spite of all the known patching methods then refer to here...

Happy Porting LeWa ROM...
-------------------------------
Hmm, it seems many are having trouble with this LeWa Porting tool...
Upon checking Master Shifu Michfood's Russian thread, found out that the below must be met or this tool will fail to operate...
Requirement on your MTK devices -> Root access to ADB
The default.prop at boot.img should be as below...
Use Master Shifu's Repack Utils, make the changes, re-download boot.img via SPFT then only use this tool again... 
This tool operates with your device fully booted up, not at CWM or fastboot...
Extract this tool to your Desktop otherwise disable UAC if you use this program at other folder or it will not work properly...

You can even use its Wireless ADB app to avoid constant USB charging that might spoil your battery in the long run...
Master Shifu told me its hard for him to maintain several threads so you gotta ask all your questions there...
To change the language to English refer to below...
v2.3 is a Donationware now, if you wanna try out then download this full older version here...
if you find it useful then upgrade to V.2.3 & support Master Shifu Michfood work...
