BUG FIXING[MTK]

Let's Begin.
If any lib missing in Base leave that - DONT WORRY

NOTE:- CHANGE LIB FILES FROM BOTH lib & lib64 folders

If you face "This rom is for GIonee P5l and your device is "Sympony H675 or any other device"
To remove this delete the assertlines in Updater-script

ALWAYS CHANGE DPI IN BUILD.PROP ACCORDING TO YOUR STOCK ROM

Bootloop when porting

Code:

*libandroid_runtime.so
*libandroid_servers.so
*libmedia_jni.so

*Repack boot.image (properly)

RadioFM

Code:

\system\bin\fmradio
\system\etc\firmware\mt6620_patch_e3_hdr.bin
\system\etc\firmware\mt6620_patch_e6_hdr.bin 
\system\etc\firmware\WMT.CFG 
\system\lib(/64)\libfmcust.so
/system/lib(/64)/libfmjni.so

Sensors

Code:

/system/lib/libms3c_yamaha.so ( acc. To device)
/system/etc/firmware (folder)
/system/bin/servicemanager
/system/bin/sensorservice
System/bin/msensord

system/etc/permissions/:-
android.hardware.sensor.xxxxx.xml

FIX Offline charging:-

Code:

In Boot.img -> sbin/healthd

System/Lib(/64):-
Showlogo

System/bin:-
Kpoc_charger

Bluetooth\Wifi not turning On\Off(old)

/system/bin/wpa*


/system/lib(/64)/libhardwarelegacy.so

Hotspot:-

Code:

/system/bin/netd

*follow Wifi fix also*

Camera

Code:

 firstly try one by one:
\system\lib(/64)\libcameracustom.so
\system\lib(/64)\libcameraservice.so
System/lib(/64)/camalgo
/system/etc/media_profiles.xml
/system/lib(/64)/libcamera.so

\system\lib(/64)\libmhalscenario.so
\system\lib(/64)\libmhalutility.so
\system\etc\permission\android.hardware.camera.front.xml

Other cam files if any
*try one by one*

CamCoder/HwDecoder

Code:

\system\lib\libOmx*.so 
system/etc/media_codecs
 
Green/pink Camera / video lagging
system/lib(/64)/libdpframework.so

SD card/Memory

Code:

mt67**.fstab in boot.img

/system/bin/vold
/System/bin/pq

System/bin/sdcard

WhatsApp Media Fix:-

Code:

from System/bin/  replace these files:-
Media

NFC ( experimental)

Code:

System/etc/: Nfc files 
System/etc/permissions/ nfc files
System/lib/libnfc****** ( all starting from nfc )

Sim1/2 (RIL)

((Trustbin.bin flash it accordingly to LP or MM etc of stock rom))

Code:

\system\etc\firmware\modem.img
\system\etc\permission (RIL)

Try these aswell if ( you may suffer Bootloop )

/System/bin/mtkrild
/System/bin/mtkrildm1

/system/bin/stmd

EXPERIMENTAL FIX for ril:-

Code:

System/ Lib(/64)/ :-
Nvram
Nvram_sec
Nvram_platform
Nvrammagentclient

System/bin:-
Gsm*** 

System/etc/trustzone

Lib(/64):-
Libril
Libc2k***
Librilmtk

Audio/Sound:-

Code:

\system\lib\libaudio* .so
system/lib(/64)/libaudiocustomparam
system/lib(/64)/libaudiopolicymanager
system/lib(/64)/libaudiopolicyservice
system/etc/audio_effects
system/etc/audio_policy
System/lib(/64)/soundfx

Sometimes if Sound isn't working fully :::::

Code:

System/lib(/64)/hw/audioxxxxxxxxx (audio files)

Bluetooth:-

Code:

system/etc/bluetooth
System/etc/permissions/android.hardware.bluetooth.xml

/system/bin/uim*
/system/bin/bluetooth*
/system/lib(/64)/libbluetooth_mtk.so
/system/lib(/64)/libbluetoothem_mtk.so

Ads

Code:

/system/etc/hosts ->replace with new files or use tweak.

=====>>ADVANCE BUG FIXING:-

Volte Fixing

( Will only work if your Base Rom , Port Rom and Kernel supports VOLTE )

Code:

Boot.img:-
Zimage ( kernel - volte supported )
init.volte.rc

==THIS SHOULD NORMALLY FIX but if it doesn't try :- ==

Code:

System Folder:-
bin/volte_stack
bin/volte_imcb
bin/volte_ua

lib(/64)/volte_imsm

build.prop(Not always required):-

ro.mtk_volte_support=1
persist.mtk.volte.enable=1

FingerPrint:-

[Try one by one][If any file missing leave it]
Usual way to fix :-

Code:

System/etc/permissions/android.hardware.fingerprint.xml
System/lib(/64)/libgatekeeper.so
System/lib(/64)/hw/gatekeeper.mt6735.so
System/(/64)/libmcgatekeeper.so

System/lib(/64)/hw/fingerprint.default.so ( can break FP in some devices)

Advanced ( if usual doesn't work ):-

Code:

System/bin/:-
fingerprintd
Gx_fpd
tee_deamon

Lib64/lib:- ( if any missing leave that)
Fpclient
Fpalgorithm
Fphal
FPservice

IF ROM DOESNT BOOT TAKE LOG ( From ADB)
adb shell logcat > log.txt
and check what is causing issue
