[One (M9) Q&A, Help & Troubleshooting] shivadow:
Exactly that, it's not worth the risk seeing as many people have reported that their phone won't boot after mismatching roms to base firmware. Updating to a nougat custom rom to a marshmallow firmware would be bad as the api's are completely different and would explain the non booting situation.

So, until someone can confirm that flashing a nougat custom rom over a marshmallow base is 100% safe I'm going to swing with "yes I'm sure".

Beamed in by telepathy.
[One (M9) Q&A, Help & Troubleshooting] Flippy498:
Re-read what I posted. I never said that it would be "100% safe" *. :p Of course there'll be problems due to the mismatch. I was only asking whether there have been reports about bootloops. (Btw, Android n and Android m don't differ as much as Android m and Android l did.) And according to this post the brick didn't happen directly after flashing the nougat rom.

However, I searched through the dev section yesterday and according to the Viper thread and the 4.x TWRP Backup thread people have been able to boot nougat roms on Android m. A lot of them faced problems. E.g. I have read about many user who used the old firmware and faced overheating and/or battery drain problems in the backup thread. They all needed to root their rom for getting rid of the problems. (Altough I personally can't explain why SuperSU should be able to fix those problems...) It seems like users with the newer firmware on the other hand don't necessarily have to face these issues. Take my phone as an example. It's running just fine without any heat and/or battery problems.

* Although I think that the usage of "safe" might imply that flashing a rom might damage your phone and that's not the case. The worst things that can happen are a bootloop or if the rom is booting fine some lags/bugs. Only flashing an incompatible firmware (via a RUU or a firmware pack) leads to damages.

Edit: Don't know how I could forget that but the answer to the OP's original problem with the reception on ICE is probably explained with Q1 of the FAQ section.
[One (M9) Q&A, Help & Troubleshooting] abdinsyakirin:
Since u didn't reply, i assume my device now damaged unrecoverably right?

EDIT: SORRY, I DID NOT GET ANY NOTIFICATION AND DONT READ THIS FORUM. VERY SORRY MY BAD. I AM VERY NEWBIE IN THIS KIND OF THINK.
[One (M9) Q&A, Help & Troubleshooting] abdinsyakirin:
Thanks for the reply. Again sorry for my previous quote just now. Yes i read that q&a section and i did not have any of the problem except no mobile internet data. I can receive and make a phone call. Only mobile internet data. I am from 3.35 firmware if i am not mistaken since there was no official update after I purchased the phone. But NOW, I faced the problem after flashed GSM RUU. I do it twice, through exe and sdcard method. I also changed my CID and MID as u told me to.
[One (M9) Q&A, Help & Troubleshooting] Flippy498:
The thing is that we don't know your original CID and your original firmware version. Not every SKU had a 3.35.x firmware version. That's why I'm guessing what the first problem might have been. If you say that there hasn't been any update at that time you probably used one of the SKUs that didn't have a 3.35.x firmware since those are the majority of SKUs that received the Android n update at a later time. But again, I can only assume what happened.

The problems you're facing now are probably a consequence of the cross-flashing. If flashing a GSM RUU could fix them then they're unrecoverable.
[One (M9) Q&A, Help & Troubleshooting] abdinsyakirin:
So if i can find my original firmware version, i can solve this problem (if the verizon does not damage it) by flashing that version on my phone right? The only thing that I remember on my phone after i bought it is, it does not have any bloatware such as kid mode app, and when i clicked on software update, it said "please connect to XXXX to check an update" or something like that. XXXX referred to service provider in usa but i dont remember what company it was. I think there are still hope to recover this device.
[One (M9) Q&A, Help & Troubleshooting] Flippy498:
I don't think that we can recover the phone even if we knew it's original firmware. That's why they're called "unrecoverable" damages.

For a GSM M9 it doesn't matter which RUU you flash (as long as it isn't a CDMA RUU). So if one GSM RUU didn't fix the situation then a different one won't be able to do so, either. And that's the reason why the ReadMe thread warns everybody not to cross-flash firmware files.

That part of my last post you're referring to was an explanation why I think that you faced problems with ICE. It has nothing to do with your current situation.
[One (M9) Q&A, Help & Troubleshooting] abdinsyakirin:
The last question I am gonna ask, will it works with CDMA network if I flash it back with verizon firmware since it no longer works with GSM? If yes then I am gonna sell it. Next time I should do more research before tweaking the device.
[One (M9) Q&A, Help & Troubleshooting] computerslayer:
Didn't you post that the CID physically engraved on the phone indicated it was a GSM model? Flashing CDMA firmware - in addition to unrecoverably damaging your phone - doesn't change the fact that your phone is the wrong model for CDMA networks.

You've a bricked phone, most valuable as a cautionary tale.
[One (M9) Q&A, Help & Troubleshooting] abdinsyakirin:
Then I should sell it for spare part only. Thanks for the reply. Since this device is uncoverably damaged, i close this thread. So guys who read this, make sure to do some research first before trying to tweak your device.

[Galaxy Note II Android Development] reis1996:
Safety net will only be passed if the ROM is purely "stock". Yea that's all I can tell you after my hours of researching
[Galaxy Note II Android Development] logosA:
What i was doing so far was to uninstall magisk and install SuperSU instead, or in Lineage roms, let CMSU as a root method.

The last day I am testing, under the guide of my ''teacher'' and for me a friend too, [MENTION=7179030]Silent Visitor[/MENTION] , to see what is this which is causing the battery drain.

What I have seen is that its maybe not the magisk but rather a LOS bug in power management (DOZE maybe) , which is keeping rom from sleep and drain out battery.

I have a Note 2 and also a NOTE 4 phone, which are at the moment running the same Android version from the same Team, AICP

In my Note 4 is also running magisk as a root method as in my Note 2 .

Note 4 is using 1.1% battery/hr and my Note 2 was consuming 2,2 - 3% per hour. My note 2 was never sleeping.

Keeping in mind that in my Note 4 is constantly running CPU AWAKE, which don't let phone go to deep sleep, due a hardware problem, is clear that a phone like that with these problems to consume less battery than Note 2 is not acceptable.

Do you know what was their difference? GREENIFY. After I installed it in my Note 2 as well , battery fell 50% per hour.

Wake-locks in ''PowerManagerService'' fell from 85% to 8% and the rom started to consume 1% battery per hour. Using the donation pack of that, was able to hibernate system apps as well.

Its still early to be 100% sure but, I think we have to look there for the battery drain problem rather than the root method selected.

So, I am asking here , if you want and like, to take that test for your self and tell me if there is any difference for you , too, or its just me.
[Galaxy Note II Android Development] reis1996:
I didn't get you. Did greenify help or make things worse?
[Galaxy Note II Android Development] logosA:
helped very much. Note 4 was having installed greenify but Note 2 not.

After i did that in note 2 , battery consumption fell 50%

---------- Post added at 09:11 PM ---------- Previous post was at 08:27 PM ----------

My next step is:

clean flash rom , uninstall magisk, flash SuperSU and all Gapps and setting I had before.

Will not install greenify, full charge battery and monitor after that how will rom behave during night.

Lets see how this will go. :)
[Galaxy Note II Android Development] logosA:
SuperSU vs Magisk - Battery consumpion

Ok , this is the end of my test about the relation of battery use and root method of the rom. In the screenshots below, you will see thaty

there is NO difference between magisk and SuperSU when it comes to battery

. Black screens are with SuperSU and white with magisk.

Tested For about 12 hours each with the same Rom, Gapps, apps.

All that battery drain that we see in all roms available now for our phone, is a problem in Lineage code, that is not letting phone to sleep and is drain battery.

The only thing that helped me is greenify.

Obviously, it helped roms to stop working in the backgrounds, when idle.

Sound

Hello guys,

I really like this rom and use it as a daily driver. It's very stable, fast and smooth, the battery is pretty good and the customization is awesome.

The only thing I request is if there is any chance to get Boeffla sound. This rom would be awesome with it. Tried to use V4A but it drinks the battery 1%/Minute. Flashed void kernel and it's awesome with the sound... but i'd like to have it with the kernel it comes with AICP. If it can't be possible, is there any way to port Boeffla sound myself?

Thank you :D
[Galaxy Note II Android Development] logosA:
do you need that to make your phone's sound louder?

You can try this:

https://xdaforums.com/showpost.php?p=72086607&postcount=4511

If something more that you need then you have to flash some mod, but I would not recommend it, since ota will wipe it out every time and also as you already said it will drain your battery like hell

[Galaxy Note II Android Development] ReDLyNx22:
Thank you for answering, but that's not what i request.

What i want is to get Boeffla sound engine. I mean to have all the options that Boeffla sound config has (DAC direct, DAC oversampling, FLL tuning, Speaker tuning, stereo spacing and the EQ it has).

Anyone know where to get the sources and how to compile?

Thank you

i did so, and result was better. my question is did you recognize the responsible process that do the draining???

actually i greenify almost every thing :D but some apps malfunctioned because of that and FC is shown more than before.
[Galaxy Note II Android Development] logosA:
Maybe you overdid it. I had never had problem in that. Here are my settings and the apps i hibernated.

[Galaxy Note II Android Development] eng_alshami:
did the maintainer plans to release a milestone or some official not nightly ??
[Galaxy Note II Android Development] ReDLyNx22:
Thank you very much. Found the source and apparently found the files i need to implement Boeffla sound engine in the kernel.

But the question now is: how can I compile in the kernel?

Thank you :victory:
[Galaxy Note II Android Development] logosA:
This is something I will never be able to help you with, since I have no clue about coding :)

All I do is testing the very good things devs (and you maybe) are creating and give us.

[Galaxy Note II Android Development] ReDLyNx22:
Thanks for the advice. I was already using void kernel ^^' and that's the reason I want to get Boeffla sound implementend in the AICP kernel, but the thing is that I'm seeing a lot of improvement on the stock AICP kernel in terms of cpu governors and sensor libs.
