Get a linux os, setup git, sync CM7 sources (around 6-12 gb), setup environment, do other necessary changes n cook a rom...n ya 1st need to make a CM-boot.img, requires kernel source which is not available, so u can use stock precompiled kernel to make cm-boot.img...all the best.

I can not say anything about CM7.

But ICS from micromax a100 should be possible for our developers.Bcoz both the phones are dual sim and as far as I know both have same architecture also.
Now it is the time to get complete ICS instead of ICS LOOk only.

I request to all the developers in this sub-forum to try to port the ICS rom from
micromax a100 to micromax a 75.

If ICS can be brought here with single sim only then it is better to get CM7

Well ,has any one tried to port ICS with single sim to MMX A 75?

I want to ask you that many roms are proted to our phone eg. lewa ,legoics etc.

From where these come?
Does there phones have some architecture as our MMX A75?

Also ,is it not possible to port roms from one to another having different processors?

If u install some app like SystemTunerPro(paid app) or Quick System Info Pro(free app) the u will notice that total ram is 201mb only, on any rom.
The ram showed in Running processes in settings does not include ram used by kernel...which costs 40-60mb ram depending upon rom...rest u see in settings..so only 106 used n 33 free for u but still total is same 201mb, install those app n see yourself.Hope this helped clear your mind.

LegoICS and the other Roms by Sagarwep have been ported from Lenovo A60 phones who have the same architecture except a 8mp camera and 3.5screen size...i think. Others hardwares are the same.

ICS has been made for galaxy y and the rest....but it hangs up a lot too. Plus, they are not totally bug-free.

Porting ICS from mtk6575 devices like A100 is very difficult. Cuz we have had a lot of other mt6575 devices with ICS......even before A100.

Ram deficiency is the main problem. But we can atleast try with the sources of cyanogenmod.

Senior Devs....lets say No to any more Hololaunchers.
Let the next BIG release be True Cyanogenmod!

Btw, cant a cyanogenmod ROM be actually ported from those available like lenovo a60?? I will post any links if i find them

Ahem Ahem! Am I still allowed to say something???

Well, who cares! I'm still gonna say it...

A100 is not based on MT6575!!! It's a Qualcomm MSM Series Processor ARMv7 revision 2.

DO NOT GROW BRAINS AND TRY PORTING THAT TO A75. Your device's processors would fry up an egg.

Regarding CM7 for Micromax A75, I've tried it and also told my review. Booted, Launcher FC and kabooom!! Brick!!

Even after brick the processor kept getting hotter and hotter until I removed battery....

So I guess, you should not try taking a chance. Choice is all yours....

Regards Everyone

WTH....A75 bricks when cyanogenmod is ported?? Well aayush....so did JETROM! A lot of us had our phones bricked by that Rom,including mine...but still we went forward and now its a classic Rom.

So.....i dont think Cyanogenmod is to be feared just cuz it bricked 1 phone. Plus it was the very 1st try yaar....not every phone is faulty.

I am sure we can make it work.

P.S: if you have already tried it out....can you please upload the sync data and the other files that you got from porting the cyanogenmod? It will give us a better footing for this porting to start

i think phones never hard brick unless playing with kernels ...... otherwise its safe to install any rom on it which might soft-brick ur device ....

Have you read the directions carefully because there will be one bit different than the other versions.



This based on mtk6575 scattered file for upgradation..
Buddy can you provide the link for the same so that we can go through the original link and follow the steps from there.

Now we joke about "format+download"

Btw gionee scatter didnt kill the phone directly. Mixing it up with different roms did ....i think

here the forum link---

HK PHONE

My Advice -
--Use default MMx Boot.img
--Do not use Mtk 6575 scattered file i think may cause brick
--Must be save Iemi File for restoring
--If not boot up or white screen pull out battery do not use again
--and restore previous rom via cwm recovery
