***How To solve Bugs On Porting Roms***

BUG SOLVING USES HIT AND TRIAL METHOD.I mentioned one or more ways to solve ,you try one by one and see which works for you.

COPY THESE FILES FROM STOCK TO PORT

FM not Working

\system\lib\libaudio.a2dp.default.so

\system\lib\libaudio.primary.default.so

\system\lib\libaudiocompensationfilter.so

\system\lib\libaudiocustparam.so

\system\lib\libaudioeffect_jni.so

\system\lib\libaudioflinger.so

\system\lib\libaudiosetting.so

\system\lib\libfmar1000.so

\system\lib\libfmcust.so

\system\lib\libfmmt6616.so

\system\lib\libfmmt6620.so

\system\lib\libfmmt6626.so

OR try this

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

Camera not Working

->Unpack boot.img again and go to BOOT-EXTRACTED/boot.img-ramdisk/init.project.rc and edit with notepad++,

also open stock bootextracted/ramdisk/init.project.rc.

Now find camera permissions and replace whole camera line with stock camera lines.

->then open init.rc of both port and stock and find camera lines and copy/replace camera lines from stock to port.

->Now repack boot.img

OR

copy these from stock to port

system\lib\hw\camera.default.so< --- (if you have two files like camera.goldfish.so delete this the one with the goldfish)

\system\lib\libcamera_client.so

\system\lib\libcameracustom.so

\system\lib\libcameraprofile.so

- libmhal.so<

- libmhalcontent.so

- libmhaldrv.so

- libmhalmdp.so

- libmhalpipe.so

libcam.camshot.so

libcam.client.so

libcam.paramsmgr.so

libfrsdk.so

libft.so

libgcomm_jni.so

libgoggles_clientvision.so

libgui.so

libimageio.so

libja3m.so

(Skip if any missing)

or

Replace camera.apk in sysyem/app

And do a ctrl+f search in system/lib for anything called 'camera', 'camrecorder', or just 'cam' and replace those.

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 Problem Fix

system/xbin/libmnlp

or, If you porting From MT6628 to MT6620, some apps at system/vendor/operator/ is blocking GPS so just delete

all apps & use MTK Engineering mode to confirmed it...

Edit in 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

Storage Mount Problem Fix

copy paste sytem/etc/vold.fstab from stock to port
