Good firmware!:good:

there are minor problems

1) see the SIM but no network ( operator Kazakhstan Beeline + Activ )

I do so and the network is working

on a purely Flash ResurrectionRemix-M-Multi-Language-v5.7.4 with this post

after flash RESURRECTION REMIX [5.8.0] + ( cache/dalvik )

after these manipulations my whole network is working and all operators Kazakhstan 2g 3g 4g

2) bad wakes up

3) some settings ( Personalization Configurations ) something that does not work.

not critical but I hope to fix!

Flashing on RR 5.7.4 of ajsmsg78?

Can I dirty flash on-top-of RR 5.7.4?

Or do I need to clean flash?
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] Manoharyadav:
Hello all,

I've been using this Rom since 3 days. Below are my observations:

1. Its quite stable and serves as a daily driver.

2. I didn't face the bugs like auto rotate issue, LTE not appearing issue, laggy behavior..

3. The only issue im facing is the screen wake up issue ( yes, ive disabled ambient display in the first boot itself)

4. Battery backup is pretty awesome:good: It discharged only 3% in 4 hours while in idle mode.. ( Lte ON, Wifi ON)

Few more bugs that ive noticed are, the camera app force closes most of the times when u launch any app that needs camera action. Exiting the FC prompt and launching the app resolves the issue and camera starts working. Google camera seems to be working smooth like butter:)

I still miss the VoLTE because without it, i need to make voice calls through the JIO Voice calling app which i hate a lot.

As the RR 5.7.4 has working VoLTE, i believe it will be made available soon.

Great work on the Rom [MENTION=4910973]Vatsal[/MENTION], Thanks

[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] nijel8:
All custom kernels built from source currently supports fk2fs...
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
Exactly. It is a bug restricted to Snap Camera. You can remove Snap and go for Open Camera instead - I am not sure if Google Camera can be integrated or not (legal perspective) but the APK could be downloaded from APK Mirror (couldn't find it in Play Store) for proper sideloading.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
I would like to put forward a humble question to n#ajsmsg78: Is it possible to consider a Helium build of the latest RR with the Harfix 2.1 integrated.

In must say that both Google Camera and Camera/Cinema FV-5 are nice cameras than the Snap anyway.

[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
Thank you very much for the latest build, ajsmsg78. I am leaning toward a full wipe since I saw some reports about bootloops in the Lineage OS thread - nothing with the ROM itself but due to the extensive rebase (seems like 7.1.1_r25 has been merged lately) and this caused some FCs if coming from older early Feb builds.

So I will do it clean this time, just to be sure.

Thank you both for this excellent Rom. It really make the Max a pure pleasure to use.

Thanks for your work, really appreciate it!
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] paarkhi:
Confirmed, Dirty Flashing causes Bootloop, so cleanflash is the only way, this build also has Magisk.

Thanks [MENTION=1397125]ajsmsg78[/MENTION] for the Helium Build and the boot.img
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
I did a bit more investigation: It is the move to 'rootless' Substratum that is a major reason for bootlooping. The discussion is similar in other threads about RR and the latest updates.

Full wipe is required when moving from any February build to the latest ones. I am going to wipe my device right now.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] paarkhi:
Are you going to flash SuperSU after the ROM Flash, if yes, please post how does Magisk handles SuperSu. Never dealt with Magisk before, I always use SuperSU. Thanks
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] dktblade:
hi, can we change position of nav bar button?. i want to swap postion of recent button with back, same position of hard key. it's conveninent for two hands using.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
I used the Magisk uninstaller zip followed by SuperSU 2.79SR3. It seems like it is a bad idea to attempt to flash SuperSU on top of Magisk.

I found the recommendation in the RR 5.8.2 thread over at the OP3 section.

My device is now booted with Harfix 2.1 on the latest build. So far so good.

Google has changed something with app verification lately so if Titanium has issues with restore, disable verify apps over USB and the general verify apps.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] paarkhi:
Thanks for the information.

Any specific reason for prefering Harfix kernel instead of stock kernel?
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] paarkhi:
Settings - configuration - buttons - navigation bar - toggle button editor and medium press

Check the screenshot
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
I think it is a good idea to update the first post with new flashing instructions due to the major change with Magisk and 'systemless' Substratum for the latest builds.

The procedure I followed is:

1. Full wipe (was on the 20170227 Helium build).

2. Flash RR + G-Apps.

3. Let it boot and settle (boot to setup).

4. Reboot back to TWRP.

5. Flash Magisk Uninstaller: http://tiny.cc/latestuninstaller

6. Flash SuperSU 2.79SR3.

I prefer to use SuperSU but it is a good idea to link the Magisk module thread for those who want to try it out:

The Magisk Modules Collection

I use Harfix due to excellent performance and battery life; it works great with RR. Flash it after step 6 above.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
Important message to those who (like me) follow the guide for creating a folder named 'su' under /system/bin: DON'T DO IT!

It worked on earlier builds but will cause complete breakdown in root privileges on the latest one. SuperSU will loose all root capabilities and the only way out is to reflash everything.

So simply put: Don't follow those guides talking about creating an 'su' folder under /system/bin!
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] dktblade:
Thank you so much. I found it. One more question, can we adjust distance between each button? :D.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] ajsmsg78:
You don't have to flash SuperSU. Root is working in the new build just fine. Plus now you have Magisk in case you want to hide root from certain apps.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] sp0979:
Can I get the link for google camera apk pls?
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] ajsmsg78:
Just do a Google search for Google Camera and go to apkmirror.com and download the latest version from there.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] paarkhi:
I don't think so....
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
I was too conservative earlier so I reflashed the ROM and kept Magisk. It also works great with Harfix 2.1, i.e. kernel replacement is no problem.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] :
People having issues dirty flashing did you disable all overlays in substrate first? I've dirty flashed every build so far. With the camera, i updated it from the play store which could be why i have no issues, the camera update wasn't available in India i know that much
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
I have been flashing the device a couple of times today due to experimentation and I would summarize those here (the latest RR is a major update with a lot of low level changes so the transition feels a bit like the step from Marshmallow/5.7.4 to Nougat/5.8.x.

1. Secure Settings is fully depreciated - it is unable to detect root and the old trick of making an 'su' folder under /system/bin is a complete NO GO. It simply break everything root related (SuperSU reflash doesn't work either so a full reflash of the ROM is necessary in such a case).

Replace Secure Settings with AutoTools; the app hasn't been updated since 2014 and all workarounds for getting it to detect root is now obsolete on 'March 2017' based ROMs.

2. Magisk is interesting but apps like StickMount is unable to detect root properly and don't do their thing; SuperSU is the solution.

Titanium Backup works and detect root properly. BusyBox also work. SuperSU is recommended for 'maximum compatibility' with root apps, though but your mileage will vary (i.e. try Magisk first, if an app doesn't work - flash SuperSU 2.79SR3).

3. Flash the Magisk Uninstaller before flashing SuperSU (as stated before).

4. Harfix 2.1 works perfectly well with Magisk, i.e. no problems with a different kernel.

Is it to be done before in ZIP file?

Open substratum, click on currently active theme, click the 3 dots (overflow menu) on the right top and select "disable installed overlays" "clean installed overlays" "clean theme cache". After doing this, it should show stock theme, once it does, reboot to twrp, take a backup and dirty flash

Is the video dark on other cameras as reported before? It feels like removing Snap and check the light balance of videos are more successful than trying to get that specific app to play well with whatever video driver change that happened in February.

I did a test using Cinema FV-5 with and without exposure value adjust and the brightness seems OK even when the setting is at the default mode. I.e. no darkness issues noticed.

So I would say that the video recording on your Helium 20170312 build is indeed working. I got the feeling that the issue is related to the Snap camera app itself, to put it simple rather than a problem with the video drivers itself (the latter should break every camcorder app).

To #sawdoctor: Please ignore those users who spend their time complaining about the ROM - your ROM is excellent, works well and is rock stable (no random reboots or anything).

My comments on some of those complaints are:

1. No issues with notifications on my device with RR/ajmsg78 20170312.

2. The USB connection is at MTP default for a reason: users complained when Marshmallow defaulted to 'charge only' and a change was being made. Now some users complain because it is MTP default. Hard to keep everyone happy.;)

3. Video recording works perfectly on the ROM using an app such as Cinema FV-5.

I am very grateful to both #sawdoctor and #ajmsg78 for an excellent ROM, which make my Helium a pure joy to use. Keep up the excellent work!
