JIAYU S3 - STRENGTHS
Finally I have found a ROM (custom) with a good compromise between performance and overheating. It is called "JIAYU S3". It is based on version 4.4.4, but it has not given me any problem about "misunderstanding storage" (I have already talked about this issue in my tutorial/review ... see "KITKAT 4.4.4 - STRENGTHS AND FLAWS" for more details). While with Lollipop & SpaceRom (during a telephone conversation of just 10 minutes) my Ecoo had a serious problem of overheating (my ear was burning and the back/top of my Ecoo was red-hot), instead with the custom rom Jiayu heats up very little. In the following screenshoots you will evaluate the real technical details & performances about JIAYU S3 custom rom (click images to enlarge):
For the comparison with the performances of the other roms (stock & customs), please visit the following link :
root - HOW TO:
Same procedure as in Lollipop (in my review/tutorial).
Xposed Framework - HOW TO
Install the apk from the official site. I suggest you the version 2.6.1 Stable.
"Wondershare MobileGo for Android" recognized the device, and I have been able to import all my contacts (in vcf format) and to install/uninstall apps without any difficulty.
INSTALL JIAYU S3 - HOW TO
Although it may seem like a cumbersome process, at first I suggest to flash the next Kitkat 4.4.4 rom :
FUNDAMENTAL :
Before flashing the KK rom, please overwrite the original recovery.img with the recovery.img that you will find at the next link :
After flashing, please copy the "ECOO_E04_2GB_3GB-jiayu_S3__os.zip" on your microSD. You will find the Jiayu zip at the next link :
And then, turn off the smartphone; turn it back on while simultaneously pressing the power button + volume up. You will see the display completely black and white lines of commands having microscopic dimensions; you will have to move to the first line using the volume + button, and confirm the command by pressing the volume -. You will enter into TWRP custom recovery. Please follow the next steps :
1) Choose “Advanced Wipe”.
2) Select Dalvik Cache, System, Data and Cache then swipe to wipe.
3) Choose “Install” from main menu.
4) Choose “Storage”.
5) Choose the storage where you have put your ROM zip file (external microSD).
6) Browse your file system and find the ROM zip file and tap on it.
7) Swipe to install ROM.
8) Reboot.
I suggest you also to install the gapps nano or gapps pico; you will find them at the next links :
JIAYU S3 - DEFECTS
If Lollipop & SpaceRom had overheating issue during a phone conversation, they had, however, no overheating issue with the apps. Instead, Jiayu has a slight problem of overheating when you run the apps. But since the Ecoo e04 Aurora is a phone first, I preferred to give priority to the overheating issue during a telephone conversation. However, I'm working to solve the overheating issue of the apps. I have found "Performance Profile" (an Xposed module) that allows to change performance per application; I'm trying to reduce the CPU usage to those applications that don't require much power.
