Sony Bravia - XLoud Engine/Image/Video HQ for GB/ICS (enhancing the sound/volume)

Hi folks
I found an interesting sony audio/image processing mods which might help in enhancing the sound/volume on out U8800. It's also reported that it increases the volume of the device and remove little distortion or noise
For image and video
1)Download attachment.(Bravia_ Engine_file)
2)Extract files on phone and put they in the directory:
Code:
/system/etc
3)Open /system/build.prop with a text editor (like RootExplorer)
and add these lines at the end:
Code:
#Bravia Engine Service
ro.service.swiqi.supported=true
persist.service.swiqi.enable=1
4)Save the file and Exit
5)Set the right permissions or open a terminal emulator and execute:
Code:
su
busybox chmod 0755 /system/etc/be_photo
busybox chmod 0755 /system/etc/be_movie
busybox chown 0.0 /system/etc/be_photo
busybox chown 0.0 /system/etc/be_movie
6)Fully Reboot the device and enjoy BRAVIA
Give it a try.
Flash it in Clockworkmod recovery
Please hit the "Thanks" button.

Do this really works or is just a placebo?

Bro try it then tell me I use this and I think it is nice sound on handfree and bt handfree is good

Placebo. This was already discussed over at sgs2 section. We dont have the needed framework for those mods to work, they exist only in Sony firmwares.

did you read any of the posts? It is quite obvious...
Sent from my U8800 using XDA App

This only works with Sony Firmware. The framework need to be changed/worked.
The ICS aurora Sound now is great and dont need this.

Porting Morrison for cousin Ruth

Hi all. If anyone is willing to help please assist me, im currently trying to upload cm 7 Morrison files for our beloved Ruth devices. I still haven't figured out how the 2nd init injector works yet.
For all charm users we can always branch the files and delete the MOTO.ROTATOR line for your devices.
If you have time, patients and sh¡t loads of guts please help or add links for me to checkout.
EVEYTHING IS APPRECIATED! :fistbump:

ruth(MB511) sensors in init.mapphone30_umts.rc

so ruth(MB511) sensors should be /dev/kxtf9, /dev/sfh7743,/dev/akm8973_dev, /dev/akm8973_aot
but Morrison sensors in libsensors/nusensors.h
#define AKM_DEVICE_NAME "/dev/akm8973_aot"
#define ACCEL_MODE_NAME "/sys/class/i2c-adapter/i2c-0/0-0018/mode"
#define CM_DEVICE_NAME "/dev/proximity"
#define LS_DEVICE_NAME "/dev"
#define LIS_DEVICE_NAME "/dev/lis331dlh"
I think porting Morrison maybe less suitable for ruth

Thanks phc, and yes I know its a long shot, I still haven't gotten to the lib files, let alone hardware. But morrison IS the closest port for us. All the other devices are to advanced for the device. Do a compare between the two, ram is almost identical, chips are close, gpu aswell. Only thing that isnt is screen size. Thanks for the lost, it will come in handy later.

OK. I re-installed system. And write script name mkbootmenu.sh
unzip bootmenuDIR.zip
adb push bootmenuDIR/bootmenu /sdcard/bootmenu
adb push bootmenuDIR/mkbootmenu.sh /sdcard
in phone side:
$su
#sh /sdcard/mkbootmenu.sh
#reboot
when MOTO LOGO click click click (loop) "VOL - " (VOL DOWN) until show bootmenu screen
NOTICE: only new system or never changed mot_boot_mode can run this script .

thank you very much, it worked!
However I still do not know why it did not run when I executed it although I did a fresh install with RSD lite.
Maybe because I used windows to create mot_boot_mode file, maybe some character issues occured.
but once again thank you!

Will check it in the morning, so far i've modded most of the make files for CM9 and my only worry is the framework.apk but so far so good :thumbup:
Almost forgot! The 2nd init and a modified boot kernel will be the biggest problems.

ruth device cpu and gpu
As far as I know, flipout and charm have OMAP 3410 CPU inside, this CPU DOESN'T include GPU. Others like OMAP 3430 in Milestone 1 does include Imagination PowerVR SGX535 GPU.

Please check this location on your device with a root explorer app:
/system/lib/egl/
and in there you will find your gpu drivers, also most phones do have gpu's although it only helps the device a little bit.
I know my device has atleast 3 .so files in there and I think thats android drivers. I must just figure out if it should be recompiled for newer versions of android.

He basically rewrote the boot script, so while booting up, it opens the bootmenu script and only then does it do a regular boot..
The normal 2nd init installer don't invoke the boot script in the same way I guess and hence it doesn't work.
Well now since bootmenu works, its like a torchlight in an otherwise dark tunnel.
Another point I want to make is that the flipout cm7 update given is in a bootloop. probably I need to change the files for basil (charm).

I think bootloop is audio device (libaudio.so) error. Maybe like when I use MB508's libcamera.so the message log show "mapped at .... " can't load library.
So should be use charm's libaudio.so to recompile CM7 sources. But maybe make some error, like media codec can't use.

The 5 step should be
"/system/bootmenu/binary/busybox vi /system/bin/mot_boot_mode", I forgot no install busybox no vi.
Defy use logwrapper to hijack, but flipout can't.
I think flipout processed init have not execute logwrapper, let we can't hijack logwrapper.
But mot_boot_mode executed.
So I rename mot_boot_mode to mot_boot_mode.bin and write new script name mot_boot_mode. Make bootmenu can execute.
And modify init.mapphone30_umts.rc
"exec /system/bin/mot_boot_mode" to "exec /system/bin/mot_boot_mode.bin", make 2nd-init can success execute init files.
In My uploaded bootmenuDIR.zip, the 2nd-init directory is modify for eclair to use.
You can modify eclair init files to test 2ndinit.

What I've learned so far is that most motorola's have the hijacked kernel from the original device, I'm not sure up to what level of Android os this works but if you dig deep enough. Its all almost the same to stock.
I hope you don't mind me using your scripts for my rom, this changed things big time.
Now to get my build machine up and running and to finish my LIB list for CM
edit: has anyone figured out the fingerprint system yet? I haven't found anything about it yet, whether it's generated or copied over.

Low Volume in Call Speakers Please Help !

Hi All I am using Lenovo K6 Power .
Last wee I unlocked boot loader and installed Lineage OS 15.1 after that I am facing low in call volume problem (volume is very low from speakers while in call even if its set to higher)
so to solve this problem again I flashed device with Stock ROM provided here but still I am facing same issue.
I tried method given in this video ( https://www.youtube.com/watch?v=_h14mrM7kxY )also but didn't worked.
Please help me urgent. :crying: :crying:

Any one having low in call volume issue?, What you did to solve it?

You will have to root your K6 Power,download ES File Explorer from Google play
navigate to folder /vendor/etc/ ,it is in the main directory of the phone
Find mixer_paths.xml file ,and hold your finger on it,then choose open with ES Text Editor
When the file opens Look for the line:
<path name="handset">
it will be around line 894 or so
and in the following section
<ctl name="RX1 Digital Volume" value="84" />
And change numeric value to something higher.
Do not use value above 99!
I was using value=95,it was perfect for me,when you change the value,save and exit,restart the phone and do a call.
I was using Lineage around 3 months ,it was perfect.But everybody complained about an incall echo. I hope you don't have echo issues.
I am using Lenovo k53a48(K6 Note) ,this fix is for all Lenovo K6 users,tested and it worked 100% on any model.
If it doesnt work,go to the official thread of lineage 15.1 in xda and read the comments,i have answered the same queation about 20 times.So good luck!
P.S. Do not go in System or sys folder like in the video! just go to Vendor folder,then /etc and find mixer_paths.xml

stock rom is not lineage rom,in stock rom,the mixer_paths file is in root/system/etc . There will be no difference if you copy the original mixer paths,i have already tried to fix that too.This fix works only on lineage 15.1 rom,because the incall low volume is lineage related problem.

[ROOT]Improved audio recording in Videos and applications

this is a modification to the files of the system therefore possibility of brick, do it under your own responsibility.
Hi, I found a way to improve the audio recording in the videos
for this it is necessary to have installed magisk, since I base on a module for the Redmi note 4x.
to install it you should go to magisk, then to modules, add (+) and look for the path where they have in file.zip (https://drive.google.com/open?id=1PxHNDThuHeiMGd8_Zbqso8JpPc2S3ih7) dont restart.
then without restart add the following lines to the build.prop:
https://drive.google.com/open?id=1CMnC-t7oHKOynkFQ89N4f_tFvRpoqlAp
then restart and you will not hear this annoying noise
the files that are modified are: system \ vendor \ etc:
-audio_platform_info.xml
-mixer_paths.xml
*make a backup of this files, recommended
Postscript: sorry for my English XD
And I hope it was clear
good luck
