[LeEco Le Max 2 Guides, News, & Discussion] diamantik:
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 5.9.021S experience for the Le Max 3 ( X850 ) :victory: .

Things what I changed and improved :

-> Dialer app - now supports call recording

-> Launcher ported from EUI 5.9.028S ( supports drawer mode )

-> Latest Super Manager APP , with data usage notification ( also from EUI 5.9.028S)

-> Improved system audio [ Fix v4 - [09/04/2019] - Even more boost the volume ]

-> Now the sound in headphones is as loud it can be !

( Tip: If you turn off Dolby Atmos , the speaker, earpiece, and headphones will be louder )

-> For change the behaviour of the deep sleep and battery optimization scrips ;

--> Please use LKT , and SysConfig Patcher

Install them via Magisk ( or via TWRP after Magisk is installed ) , they help to improve battery life and performance !

1. LKT - link to download : https://github.com/Magisk-Modules-Repo/legendary_kernel_tweaks

Profiles description:

Battery: Can acheive ~2 hours or more longer on-screen battery life, may lag in some scenarios where the load fluctuates dramatically.

Balanced: Can acheive ~1.5 hours or more longer on-screen battery life with little performance compromise (recommended).

Performance: Can acheive ~1 hour longer on-screen battery life , same as balanced profile with more responsiveness. Choose this profile for gaming.

Turbo: Ideal for intense high demanding tasks, where the load drastically fluctuate (not necessarily in games) . Will ensure reducing lags by ~90% for no more than ~20% increase power in consumption.

2. Sysconfig Patcher - link to download : https://xdaforums.com/apps/magisk/module-sysconfig-patcher-t3668435

-> Removed many useless applications

-> Performance, RAM Management , Wi-Fi and Signal , UI responsiveness and platform Tweaks :cowboy:

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

Download Latest Update ( Скачать : ) : http://bit.ly/2uWdQcP

(The " R(Number) " means the release number of the ROM , like R4 - fourth release)

*** If you will get some errors with the LeEco Account when you are in Setup Wizard , you will just need to reboot device OR you can setup the device without the Data and Wi-Fi enabled .

How to install :

1. You need to have the bootloader unlocked , and the TWRP installed . ( How to do that : 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 : 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 a wipe on system , data , cache .

Also please take a backup of all your files :good:

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

Note : The LTE B20 band is not working , you can NOT use the EUI6 modem or the " Super modem from EUI 5.9.020S " to get it working. The B20 will appear , but in calls you will not hear nothing , and you will not be heard by anyone

3. Download the ROM ( form the link above )

4. Boot your phone in TWRP ( from power off state , hold volume up and power button , until TWRP appears )

Now from there :

( If the TWRP is promping " Data Encrypted " then : )

--> Tick "do not show again" and the swipe to allow modification. ( if promting )

--> Skip device encryption by clicking "Install" (if the storage size is 0mb or no folder is showing while trying to install, then the device is encrypted. )

--> For solve that, click "Wipe" --> choose to " Format Data " and type " yes " and swipe to format . It's going to wipe EVERYTHING in the internal storage (that's the purpose of device encryption, to prevent unauthorized access to the storage).

--> When completed, go back, click "Reboot" --> "Recovery" , this will restart your recovery (very important, do not reboot the phone into system otherwise you'll start all over. Reboot into recovery, not system).

5. Copy the ROM and the Firmware & Modem from your PC to your phone internal storage

6. Now in TWRP , tap on " Install " , and locate the Firmware_&_Modem_x10.zip and flash it.

7. After flash the ROM.

8. Now you can root with Magisk ! :o

9. Flash LKT and Sysconfig Patcher via TWRP ( if don't work , try via Magisk Manager ) ;)

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

( 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 )
