Well, after a long time of learning in the world to change ROMS, I managed to make my own.
The rom is based in the 20140112-000001 of Jiayu.es which was very stuffy and gave some FC. What I have done is clean of unnecessary applications (I still have to reduce the size of some apps). I have to say that if that goes smoothly.
Because it is the first that I do, I would like to comment that all faults found (few or none) and suggestions, so we can fix them in future updates. It remains to optimize it more, removing languages, optimizing images, but that will be for the v2.
Jiayu ADRIANMM2 G2S 4.2.2 ROM V.1.9
Changes in system:
Changed the colors of the LED notifications (full, medium, low) for the mobile into deep sleep. To whatsapp change it from the settings.
Default language to Spanish on first boot.
Default network to WCDMA / GSM (Auto) to save battery
Removed the R roaming in blue color.
Reduced all transitions in 200 ms each (just below the low but, as you may see)
I autobrillo improved, save battery.
Bootanimation changed to Google Edition, takes less mobile initiate.
Improved scroll
Changed color to blue locking Holo
Added busybox
Performance Tuning
Battery saving settings
Added gps.conf improved. Already comentareis such, I usually do not use much the gps.
Changes in Application
Besides cleaning, have not made many changes. All apps are visual changes. Coming also performance.
Added the app Camera + JB
Added the Clock app from JB +
Changed the name of some apps
Added File Manager.
Added in settings section Rom Extras Adrianmm2 with Full Titanium Backup application. Coming soon will try to add more apps as the gravity box. “All” these apps will relate to mobile settings, I mean, I will not add the app WhatsApp.
Launcher: Apex Launcher, very fluid and smooth. It has also changed the wallpaper. There is a FC in Settings> Display> scene because it has removed the default launcher
Keyboard: Google. It works pretty well, simple and with enough options.
Added Xposed Framework and Gravitybox. Now with Gravitybox and 4.2.2, many more features and graphics settings are added.
Other changes build.prop
Added on improvements in GPS tracking applications
Improving Quality Photo
Improved speed HSPA and WIFI
Minor changes
Optimization and Performance
In this section are other changes that affect performance differently:
APPD Zipalagin all the folder / system / app /
Odex has made some apps to load faster.
Eliminated some background processes.
Although this is not a modified mia, you can get settled the PurePerformances X, which improve the rom. Os you can download it from here. X PurePerformances official post here
Installation
Put the rom on the SD and start the mobile in recovery mode (CWM)
IMPORTANT! Make a backup of the rom from the settings section. I am not responsible for any damages that may cause your mobile
Make the following wipes:
-Wipe data / factory reset-Wipe cache partition-Advanced-> Wipe dalvik-cache-Mounts and storage> Format / system /
Install: install zip from sd card and search
When you have finished installing reboot system now
Note: Always install a new rom is recommended to calibrate the battery
What remains to be done?
Let me make clear that this does not affect performance or anything like that rom, but would not have posted. They are small improvements that I have to do
- Fix the FC gives Scenes
- Fix visual brightness setting FC in quick settings notifications curtain. It does not affect the behavior of this, you can usually use but leaves a white band on the switch.
-Integrate Gravitybox Settings. Do this now because I gave compilation errors.
-Optimize weight and reduce some unnecessary applications and clean language
-Fix a bug that you meet (I have not seen any) and comenteis me.
