Alright this is the experimental ROM
results will be sketchy .
Since the community is tight knitted ,I took The last ROM (hybrid v3 )as normal base .
Apps replaced : Nemus Launcher intead of ADW
and ROM toolbox added
Scripts : same that of Leandros

Changes over other ROMs:
Uses ext2 as Filesystem
I am to believe mtdblock2,3,4 are system ,cache and data partitions
The mounts points were changed likewise
Additional library modules for ext4 ,swap ,compcache ,cis/tun added
Installation :
DONT WIPE DATA AND CACHE
when you install the ROM Data and cache will be formatted to ext2 automatically (provided your CWM has a shell)
Chance of the zip working : 1/10
the usual install from zip option .

If ever the ROM boots then i need the output of the following commands
Code: 
mount
Code: 
free outputs
Code: 
cat /proc/filesystems


If the ROM doesnt boot :
A.)there is mkfs.ext2 binary
manually format /dev/block/mtdblock2 to ext2 as follows
Code: 
cp /sdcard/mkfs.ext2 /mkfs.ext2
chmod 777 /mkfs.ext2
/mkfs.ext2 /dev/block/mtdblock2
mount /dev/block/mtdblock2 /system
Then give output and check the mount point of mtdblock2
Code: 
mount

I will try to take things slowly then :( step by step
Adios

cool gautam whose zip I kanged
 
It said like [!!!!] Formatting /system /data and /cache to ext2 instead of yaffs2 ...
Maybe it worked .....
assert failed: write_raw_image("/tmp/boot.oimg", "boot")
E:Error in <location of zip>
(Status 7)
Installation aborted

-i am on stock
-just backed up then flashed ur zip
-using cwm rec 4
 
Can you try flashing the kernel with fastboot and tell me if the kernel works ?
What was the output of
Code: 
mount
command when the installation failed ?

when i tried to flash boot.img from ur pakage it returned me that
sending 'boot' (6910 KB)... OKAY
writing 'boot'... FAILED (remote: flash write failure)

also what do u mean by mount command ?
also can we chat over irc channel of micromax a70 that will make things more live ;)
 
@karandpr i do not want to be a jerk here but just like
by ur scripts and binaries even though we convery yaffs2 to ext2 is there any way to revert back?
caz only ur boot.img supports it !
hence if i convert to ext2 i may not able to revery back to yaffs2 !

what is the advantage of ext2 as file system? can you explain

ext2 is faster and native linux FS as aginst yaffs2 which is a nand specific system . It's lighter on processor than yaffs2
yaffs2 is tailored for nand devices to enhance durability but after two years it doesnt matter anyway
I would prefer Non Journalled ext4 since it doesnt melt as ext2 does .
Personally I use JFS for lowest CPU usage and btrfs on second partition (for the max performance ) but they have to be compiled with the kernel which is not possible due to lack of source .
Reiserfs has much faster and XFS is somewhat in middle
Nothing wrong with yaffs2 but hey ext4 is Android official after Gingerbread .
So I wanted to try ext2 .
Like I said ,it's experimental stuff and I dont think many users will use it due to severe lack of convenience .
 
The zip doesnt work .
Probably I will make a dual boot yaffs2/ext2 but that defeats the purpose .

I need someone with adb logcat to actually trouble shoot and a time machine .
Both are unavailable :p .

Well i tried level best to get a time machine but unfortunately i did not get it as of now ! currently :D
and regarding Logcat working you will surely need another beta tester as the debugging in my phone was not working from the day one ! i used to get everything via the wifi adb or android terminal
well but the big boot.img problem solved !
 
Oh yah one more thing @karandpr is it possible to solve the wifi bug in v2? if a beta tester was not found for v3 ...
it is a good rom... just the wifi hurts !

well i just see micromax logo and for one hr it stayed there and then we had to remove the battery to restart in revocry mode to get the old rom.

we did all way to install

first we try to install with clearing data or wipe then we tryied by wipeing data .

still no luck.
 
that how i was back to hyd 3.

i mean i didnt made a recovery. i has hyb3 save on my folder. once ur rom didnt boot i want back to cw recovery and flashed old hyd back.

i guess that one an the same thing of flashing stock rom.
