[Q] Kernel source question - Android Q&A, Help & Troubleshooting

I own a Xolo q1000/cherry mobile OHD
Specs :-
1.2 ghz quadcore mt6589
powervr gpu
4gb internal( rest not worth metioning here )
There is another device called BQ AQUARIS 5 HD
It has the same specs as the above device
even the same gpu and all the placement of the hard keys is the same as my device ( BUILD AND SPECS ARE TOTALLY SAME, EVEN THE SCREEN )
But it has 16gb internal ( only one difference )
Xolo :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Aquaris 5 HD :
Hope you can see the similarity
Now my problem here is that the source of aquaris 5 HD is available and my friend has used it to make a custom kernel for my xolo, but it doesnt boot up..
Can someone pls help me with this ??
I want to change the files corresponding to the internal memory..
Help will be appreciated

Make sure you're getting the mount points right,if the only difference between the phones were storage then, ADB would start when kernel initialises if you added it in the ramdisk. Get a dmesg or a logcat to understand the problem.
An easier do to check if the kernel works is, build a recovery with the kernel and check if it works.

Well I have been been trying to make the kernel... I got an idea.. Will changing the recovery.fstab in the source be helpful ?? And also can I copy some files in the source parts of which are having similar specs?? Like touch etc...??

However similar your device maybe, the calibrations may vary
"some calibrations settings are on the device itself.
Search with an root explorer under /sys/devices/platform and check under the MT-IC's (eg MT-i2C.0)
Under those IC's you'll find most of the devices (sensors,, etc), that are being used.
Example
/sys/devices/platform
MT-I2C.0
0-0039 - s3202 ---> s3202 is the TouchPanel
MT-I2C.1
1-0018 - FM50AF ---> Camera Lens
MT-I2C.2
2-0018- BMA222 ---> Accelerometer
etc, etc.
Some sensors special configs, can be found on those IC's, others are under /proc."

whenever i use the MAKE command this happens.. how to fix it ?
Code:
Command 'make' is available in '/usr/bin/make'
The command could not be located because '/usr/bin' is not included in the PATH environment variable.
make: command not found

If you exported your path dynamically via terminal for that instance, you need to do
export PATH = path_to_dir:$PATH
this will include the existing environment paths also.

Instead of doing that try "make mediatek-configs"

gcc compiler
Do you have the GCC toolchain?
If you do, try typing:
export CROSS_COMPILE=~/dir/where/gcc/is/installed/bin/arm-eabi-
if you downloaded the entire google source it will look sth like:
export CROSS_COMPILE=~/google/source/dir//prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-
