Great, fast ROM. Thank you. I have 3 problems.

1. The error occurs randomly every few days. When you turn the phone off and on again, the phone goes into a loop. It starts, I can see the desktop and restart. Only re-clean installation helps. I noticed a similar problem on the official Lineage OS 17.1. I have le max 2 x829 (firmware 30, Open GApps pico).

2. During the phone conversation on the original LeEco headphones, the volume cannot be changed. The problem does not occur in other situations. Appears only during phone calls.

3. Unfortunately, this great software is characterized by very high power consumption. For example: at night, 2.5% rest per hour. On android 9 it is on average 1.2% / hour. The situation is even worse during normal use.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
1. Sorry to hear that..I don't face this issue so i can't know what causing this..logs??

2. Maybe this be there because of leeco headseats..I don't have and i can't test..

3. Here idle drain is 0,98 per hour..check and restrict your apps..

Thanks for your reply..

Hi Arkadia,

AS you can read above i had "the same" Problem. A reformat oft infernal storage helped.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] arkadia_1969:
Loop on startup

Cris thanks for the reply. I have always admired your work. I've been using your ROMs for years.

I will return to point 1.

Today I tried to install your ROM several times. I formatted DATA partitions before, then wipe all available partitions. I have also changed the format of the CACHE and DATA partitions to f2fs. Installation is correct. I did not install any additional programs. I only did the default programs update. Unfortunately, the phone after 2 or 3 successful reboots goes into loops. I am asking for help because at the moment I cannot use my LE MAX 2. I do not know if it is a hardware or software problem. I use your TWRP. I'm not a programmer but I noticed that the logcat files differ in the CRASH section. I do not know why. I generated these logs one by one. Both in attachment.

EDIT 27.04.2020

I found the cause of system instability. I made a mistake during the initial system configuration. After providing the email address and password for the Google account, I chose the "Restore previous system settings option (wifi password, call history and sms etc." and used an earlier copy of the system settings from lineage 16 (android 9). At the moment everything works quickly and stable. Battery consumption is already normal.

Thank you all for your help.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] Law_Ger:
Tried the vanilla Version of Rom? On the phone of a friend the included gapps caused the Problem. Try vanilla with pico opengapps, for him it helped.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ShadowFlarer:
The rom is very good, being using for a while now, i have only one problem, some apps, when come down to take pictures, doesn't work, the camera opens and then the app freezes, this is happening a lot with bank apps.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] arkadia_1969:
Thank you for your help. I installed vanilla Version but the effect is the same. Several times the correct restart and then the loop.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] AZEDJ:
Bank app

Revolut app is not compatible on play store or or was with revente os
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] valy_cta:
This is because you have to hide Magisk. Go to Settings of Magisk, hide it and then restart.

If you don't hide it, the phone is seen as incompatible.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] bakardi74:
Hi Cris! Hope you're fine. Still having issues with muted audio messages on whatsapp. I've already disabled "OK Google" and Google Assistance but after a while the phone is on the problem appears again. In case, do you know if Google has fixed the bug?

Hope you will soon upload the new official build. Thanks in advance for your kind feedback. Bye!
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] valy_cta:
On Vanilla there is no such issue with the voice messages from whatsapp.

Installed the latest version yesterday, initially without full wipe and the phone did not pass the booting owl. I also loaded the kernel which for sure didn't do good for my accelerometer as there is no rotation and fingerprint doesn't work anymore. I'll try to come to another kernel to see if it works.

One more thing, the brightness slider in the notification are is a bit messed up and comes on top of name of operator.

Edit: It seems that all sensors are not working. Just installed fresh with all wipes and it still doesn't work the proximity sensor, accelerometer, fingerprint sensor, etc.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
hey.. i don't know if they fixed or not..on my phone working without ok google active so it's ok for now..

i hope they fixed soon..
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
That is another (propably) device mesedup issue..Try to format data or flash another rom and make tests..

I have onboard Vanilla since day one..I haven't all these..
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] bakardi74:
Thanks Cris. Just to be sure, is Google Assistant active and OK Google disabled or both of them are disabled?

Will you soon update the standard Pixel buuild of the rom (with Gapps included I mean)?

Thanks in advance for your feedback.

Ciao!
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
Yes..i will with May security patches and Android 11 R Heads Up, Notifications, and UI interface..

About Google assistant yes.. I have them both closed..
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] valy_cta:
Hey Cris, thanks for your work on this ROM.

Strange is that the kernel is ok, but after installing 26.04 ROM, the sensors stopped working. I've tried flashing Lineage and Aosip with same results. All was done with full wipe except internal.

But... after flashing Vanilla 11.04, my phone was good again. After installing the previous version, I've installed the latest kernel and it's fine. For now I have to stay away from 26.04 for some unknown reasons... I will mention again that all flashes were completely clean, my unit being an X820.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] bakardi74:
Thanks a lot for your great support Cris. Seems to work again now. Looking forward to flash new build once it will be available!

Hi

When select long press to divide screen it doesn't work always go to recent apps. I select sequar to do this function.

Thanks great rom
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] valy_cta:
For me it works. Select another app from "recent apps" and it will divide the screen if the app supports split screen.

What o said is the square botton doesn't work. I select main botton and it works.

Can I use the ota or do i really have to do a clean flash?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
Of course you can. That's why is there..No need any wipe.

[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
You might have remaining encryption from previouw rom or wrong TWRP.

Make all wipes except internal and try again..Otherwise you might need to format data.

Hi [MENTION=6843607]crisbal[/MENTION]

I am very eager to migrate over to this rom, I'm currently on Revenge OS. However I want to be able to retain my data and I'm wondering what is the best to do so, so looking for your advice on that.

I've backed up my data with Google but was wondering if on the restore that will cause issues with this rom's Google apps. And if Google backup is the best way to bring data into this rom once installed?

Also, does the LED work on this rom? Let me know.

Thanks
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
I don't hink Google restore is the best way..i think titanium solution is better..or to backup data through twrp..Led working of course..Screen cast Miracast all IRs and many other stuff..

Hi Manetto,

i think the best way to backup and restore is migrate app. But Luke titanium backup you'll need root access.

Hi Cris! Everything works smoothly and perfectly on new official build (Pixel version). I have only one question: could it be possible to wipe in one time the cache of all installed apps? Maybe could you implement this feauture in future builds? It could avoid a waste of time by wiping app's single caches in the app setting menu. Thanks in advance.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
I know. It's complicated between Derp platform and our trees..we will see at the feature..
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
It might be single app issue because it doesn't included on white list apps for audio..

It might be on LOS because we all sharing almost the same trees and updates..

Hi Cris! I've noticed something in the new official Pixel build. There are now two Phone apps - the Pixel one and the AOSP one. Is this normal? Why did you put AOSP Phone app in addition to the Pixel one? I've deactivated the AOSP Phone app. I think i twill not cause issues. Thanks for your feedback. Ciao.

Hi Cris!

I've installed the latest 09/05 vanilla and it seems that the sensors are again not working. The last build that everything was ok for me was 11/04. Has anything changed since then? I don't know what to try. I'm on the latest LOS 17.1 derpfested kernel also.

Edit: Seems that Pixel users are having same issues with not working sensors. It's not all of the users though... Luckily I can revert to a working build, unlike those guys who are stuck with a phone with no sensors.

Ok. No Problem, just found it. Would be nice if it works in future

---------- Post added at 04:43 PM ---------- Previous post was at 04:40 PM ----------

How you wanna that I Send you the app?

You can find the app on the playstore.

In Evolution OS microfon works in this app. Maybe this Information can help you. But I have no idea what are different there. Kernel looks like the same for me, but maybe I'm wrong.

CrisBal, thanks for the advise, I have gone ahead with the rom switch I'm officially on DerpFest, great experience so far. I do have to report to you that my led isn't working for notifications, only for battery charging status. Any suggestions on how to go about troubleshooting?

Thanks again.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
Led should be working for everything..

On my both devices..x820 x822 Vanilla and Full ROM working.

Check Derp settings notifications tab and one by one Apps you wanted if they have permissions or not to show notifications and led pulse.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
This hasn't to do anything within kernel..

It's audio and permissions stuff.

Maybe evox has different audio configurations.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
After many users requested ROM including AOSP dialer because it has in board Call recording by default and Video calls are easier.

You can put Gdialer any moment you like. Permissions for Gdialer are inside as well..
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
Many things changed..

If you want just make a try with Full with Gapps ROM and post if there sensors working for you..

I have made huge changes on device trees and these will be the final for this month of course.

I will make a new Vanilla build today including new fixes.

Consumer IR fixes and patches to have working all available Remotes like Zaza Miremote and others

Power Hal changes

VNDK enabled

Small kernel adjustments

Hi Cris! Many thanks for your reply. I've noticed that my device doesn't see the persist file in any later build of vanilla after 11.04.

In the screenshot attached, this is from 11.04, the shortcut for persist folder is seen in this filemanager as a normal folder. In 09.05 this shortcut is seen as the icons at the bottom of the screenshot, making me think that there is something wrong with how my device see's the sns.reg file.

Any idea how to fix this?

You guys are absolutely fantastic!

I am a computer scientist with three children and I am a big fan of custom ROMs to keep unique and lovely hardware from going in the bin.

I just installed this ROM on a phone I gave to my eight year old daughte. I have tried many ROMs for this phone over the last coulple of years with my older daughters and while they worked, there were always some issues. But this ROM, oh my ... This ROM is stunning.

I am amazed to see this four year old device run better than the new snapdragon 855 phone that I purchased for my older daughter.

Deep respect from one computer scientist to the team of others that poured their heart into this project.

Your labor is appreciated. I noticed how hard you worked and my daughter has a device that works as well or better than anything that can be purchased in 2020.

Sincerely, thanks guys...

Hi Cris! Thanks for your help.

I've managed to pull persist.img via adb, but whenever I flash it onto any newer build, it reboots into fastboot. Also one more thing is that whenever I flash dirty after 11.04, my phone is in a loop on the owl logo, it's never loading to the desktop even after half an hour.

Seems that I'll have to revert to 11.04 as that's the last working build for me.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] Ascoman:
Hey Cris. Love the ROM. But I'm having a little problem. after every update (or dirty flash) a message error about not mounting system partition appears when the flashing starts doing the magisk stuff and then ends and reboots. After the update I have to reinstall magisk and modules manually again. I'm using your twrp. Is there a setting I'm missing or something?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
Forget dirty flashes.. you're facing device issues.. maybe enforcing build isn't suitable with your device or doesn't like it..:p

Make a deep clean installation.. Check TWRP or and put latest official.. Change repair partitions data and cache (recommended f2fs) to be sure that everything is ok..Then make a format data ...Reboot to recovery and in Settings enable "Use rm -rf instead of formatting"...Then reboot to recovery and try to Flash clean again. Be careful.. this process will delete everything inside internal storage.. Take backup your stuff before proceeding..Gluck

PS if again latest build doesn't work for you make this. Pull out from 11.04 build the boot.img file and install it through TWRP. If with this booting is something related your BL.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] CrisBalGreece:
I know that the 20.4 Magisk add-on has some mounting issues..Try beta version 20.5 if persist give a try with latest 3.3.1-1 TWRP to see what happens.
