Disclaimer : I am not responsible for bricked devices, dead phones, or you getting fired because the alarm app failed. Please do some research if you have any concerns about doing this to your device .

YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, your data , i will laugh at you.

I am happy to present you , the best EUI 5.9.21S experience for the Le Max 3 ( X850 ) .

Things changed and improved :

-> Launcher now support drawer mode ( ported from 28S)

-> Latest Super Manager , with data usage notification ( also from 28S)

-> Removed many useless applications

-> Improved system audio

-> The quiet sound in headphones is now fixed

Tip: Turn off Dolby Atmos , the speaker, earpiece, and headphones will be way louder .

-> Kernel Tweaks and battery optimization scrips

-> [ Update 13/10 ] Changed the behaviour of the deep sleep.

If you encount a bug , please tell me the details in this thread .

** The " R(Number) " means the release number of the ROM , like R1 - first release :o

The Deep sleep tuner :

http://bit.ly/2EwB9kU

*Install via TWRP above the current ROM , you don't need to change or wipe nothing .

It really helps with the battery life

How to install :

1. You need to have the bootloader unlocked , and the TWRP installed . ( How to do that ( my post link) : https://xdaforums.com/showpost.php?p=76620374&postcount=7 )

**After unlocking the bootloader , you get a green notification led and the phone not turning on , when you try to boot your phone .

[ THE SOLUTION IS : To boot into TWRP ( volume up and power button ) and from TWRP , tap on Reboot --> System , this will boot the phone normally , currently we can do nothing to solve this :crying: ]

Note : If you come from another ROM , you will need to do an wipe on system , data , cache .

Also please take a backup ,if you have already TWRP , and in case you want to restore back.

2. Download the "Deep sleep tuner" and the " 21S Firmware & Modem by [MENTION=6416309]moto999999[/MENTION] ": https://androidfilehost.com/?fid=674106145207488760

3. Download and copy the ROM , Universal_GMS_Doze.zip , and 21S_Firmware_&_Modem_x10.zip inside your internal memory

4. Flash the 21S_Firmware_&_Modem_x10.zip

5. Flash the ROM

6. Flash the Magisk

7. Flash the Universal_GMS_Doze

Apps that I recommend : ( they are not in the ROM)

( Updated 12/10 )

( Currently using all from this list )

1. Power Shade ( adds a new notification bar with android P style , with changed notifications and toggles for all the things. )

**Tip : Select USA region for showing apps in status bar , not an 3 dot circle :o

2. Add Away ( Removes adds system-wide)

3. Install button Unlocker ( Allows you to bypass the restriction "screen overlay detected" and allow the permison to apps )

4. AndroiTS GPS Test Pro ( for GPS to indentify you faster , first time after instaling the ROM )

5. Greenify - helps with the battery life

6. Volume Booster by GOODEV - boost even more the headphone sound :laugh:
