This is for Official and Test builds of TWRP for the LeEco Le Max Pro (max_plus / LeTv x910)
Official Downloads:
https://twrp.me/leeco/leecolemaxpro.html
Test Downloads:
https://sourceforge.net/projects/lineageos-for-max-plus/files/TWRP/
Sources:
Official: https://github.com/TeamWin/android_device_leeco_max_plus/
Tests: https://github.com/LineageOsMaxPlus/
Platform Tools (adb/fastboot):
https://developer.android.com/studio/releases/platform-tools.html#download
Installation:
Make sure your bootloader is unlocked
Download the recovery image from above
Reboot into fastboot
Run this command (Change the .img to whatever the name of file is you downloaded):
Code:
fastboot flash recovery twrp-3.5.0_9-0-max_plus.img
Once it is flashed, please force a reboot to recovery by holding down the Power and Volume Up buttons at the same time until the phone reboots and you see the LeEco logo and the word "recovery" underneath it. (This is because if you allow normal boot after flashing TWRP and you are using EUI ROM and your phone reboots to EUI ROM? It will overwrite recovery with stock EUI ROM recovery. Forcing a reboot from bootloader to recovery prevents this issue)
Known issues:
Sometimes the boot animation gets stuck and doesn't go to menu. As a workaround, please tap power button twice.
Can't flash some Marshmallow based EUI ROM versions (gives errors such as error 7). Please downgrade TWRP to 3.2.1-1 or earlier (such as 3.1.0-0 which is marshmallow based TWRP for x2) as those don't include quota storage support which is used on most Oreo and up custom ROMs. It might also require formatting data partition (Wipe > "format data" button > type yes > checkbox on keyboard)
For the TEST builds of TWRP? Please let me know if this works. If so? I will submit it to Gerrit for official updates.

@ThE_MarD is just a curiosity why you post stuff for x 910 in lemax 2 thread??

Heyyo, w00t! This post is linked on the XDA article for official TWRP builds! :good:
So there is unofficial LineageOS 16.0 unified x2 & max_plus builds here:
https://forum.xda-developers.com/le...2x-lineageos-16-0-pie-leeco-le-max-2-t3850871
There is some bugs that are in the second post of that thread that I'd recommend reading for any max_plus user who wants to try it out... But it's quite awesome that max_plus gets to jump from official Marshmallow EUI ROM to Treble enabled Pie Custom ROMs
My current sources are here and I could use some help with the ES9018 Hi-Fi Audio DAC which is the current issue holding me up from LineageOS official unified builds... If anyone could help me with the DAC stuff? That would be GREATLY appreciated

Original Post:
@antony82 , the reason is simply because max_plus users post in Le Max 2 XDA forum section and there is no Le Max Pro XDA forum section.
Also, I'm working on LineageOS 16.0 for max_plus and I believe once I get it working? I can convert the work to the current x2 device tree and we can have unified x2 and max_plus builds, which means any custom ROM that would include the same commits will then be able to support both x2 and max_plus as well. :good:
Similar to zl1 has unified builds with zl0, or oneplus3 has unified builds with oneplus3t.

:good: thanks

Are you by chance an owner of a max_plus? If so can you please test this build of TWRP?
One max_plus user confirmed it worked... But I'd rather wait for extra confirmation before I apply for official TWRP.

Heyyo @gozef14 @Cateye @sean_han and @LxMxFxD
Please try test 2 TWRP from here, I think the pingpong-split adjustment I made will help once it gets past the initial boot which might have split rendering, but one max_plus user confirmed

---

Heyyo, test build 4.2 is up! Hopefully it helps with that video lag!
update: nope, please check test build 18 it should be good

---

Heyyo, NEED TESTS DONE ASAP! I think this truly IS the fixed video lag and screen wake fix! Please report back and let me know!

This is all based on TWRP 3.3.0 Android 9.0 Pie

Heyyo, official TWRP builds for max_plus are up.

---

Heyyo, new test build going up! Test-22-twrp-3.3.1-0-max_plus_UNOFFICIAL has kernel fixes so that it displays properly (TWRP doesn't need the converting of dsi panel from cmd to video like custom ROMs do) and also updating the decryption blobs from CAF.

---

Heyyo, my super duper awesome max_plus tester confirmed the kernel fixes work perfectly on TWRP, so the official TWRP build for max_plus was updated to use it.

---

Hi,
As an owner of a Leeco Le Max Pro X910, thank you for your time and effort. This great phone deserves a stable and updated ROM. If functional and stable Lineage OS 16 could be successfully ported to it that would make us tremendously happy. Thanks again, You gave us hope.

---

Heyyo @txekalzen , LineageOS 16.0 is ported to max_plus. The only thing that doesn't work is the Type-C to 3.5mm headset adaptor as I haven't figured out how to backwards engineer the ES9018 Hi-Fi Audio DAC so I can build an amplifier in the device tree. All my unofficial LineageOS 16.0 builds are unified x2 and max_plus.

Thank you for you comments. Today, following your instructions step by step I flashed your unofficial LineageOS 16.0 build and now I am a happy owner of a "new phone" with Android 9.0. What a jump, from a buggy Marshmallow to a delicious Pie.
Thanks again.

Hello. I have problems with TWRP. I reboot phone in bootloader mode (I can see penguin on screen), then I flash TWRP through adb (fastboot flash recovery twrp.img), and when I restart phone in Recovery it's just stay on LeEco Logo and below logo is written Recovery. I tried tu press twice power button and to reboot phone again in Recovery but nothing helps. I have installed Ressurection Remix ROM. Have you any advice? Also, I can flash X800 TWRP 3.3.1.0 and I can boot to recovery, but can't flash any x900 based ROM.
And also I have jus one question. On back of my phone is written something in chinese and LETV X900+ Maybe it's regular X900, not X910 and because of that TWRP doesn't work?

---

Heyyo @txekalzen , nice! Hope you enjoy LineageOS 16.0!
@MasterChief2 , I'm sorry but x900 is the LeEco Le Max with only the Snapdragon 810 and it is not supported on the LeEco Le Max Pro x910 builds which have the Snapdragon 820. You will have to use TWRP built specifically for your device.
I do not own a Le Max x900 and I am unfamiliar with the kernel source code or device tree for it, so I cannot maintain it, sorry bud.
