How did you come to this conclusion? I'm seeing in top that both use 0.0% CPU.

On a separate note you should directly credit who created the ROMs you reuse in your EDL package. Saw someone post on another thread they were on your B32+10 RR-O when it's actually Kranoners. Without indication the ROM was created by anyone it's basically assumed by omission that you created it when you're only indirectly offering it and have your name on the zip. Then you take donations for their hard work which they both regularly hinted for donations. Probably a part of the reason both @Kranoner and @NFound who's ROMs you repackage are no longer developing. I hope no one has mistakenly donated to you for thinking you put the work into making, fixing and supporting the ROMs.

Sent from my ZTE Axon 7 using XDA Labs
THe conclusion is obvious. All the pre-processing of V4A and ATMOS is done by the CPU since those softwares are hardware agnostic. Any processing takes CPU and I have noticed about 10% more battery drain when using V4A. I don't mind since the results are awesome. Regarding the HiFi DAC, it doesn't affect CPU but the AKM DAC requires extra power. Even the stock ROM warns about a higher battery drain when HiFi audio is used.

The other issue has an easy explanation and solution. I have always gave credit in the OP to NFound and Kranoner for their ROMs and Kernels in the post introduction, ALWAYS. And I clearly state that the ROMs and Kernels in the EDL packages where created by them. I understand that some people doesn't read all the info in the posts and go directly to the download section, so I have just added clear credits next to the reference to the ROM or Kernel in the bundle description to ensure no one misses the credits.

Regarding donations, I never asked for them and I never received any, I do not invest all these hours for a few hundred dollars, I do it for pure fun like many others around here. I share my packages, tools and tricks just for helping others, not for getting money, or enlarging my ego. All I have asked for is to press the thanks button just to know if my time is helping people when I answer their concerns. Why I placed my nick in the filename? it is easy, it is a quality stamp telling everyone that I guarantee that the EDL bundle is certified by me. Everyone can rename it after downloading so it is not a big deal. I have tested many roms and kernels and these bundles are carefully curated to be stable and easy to install. That is the added value here that is very important for newbies that arrive here looking for an easy way to get Oreo. By the way, Pie is not yet stable enough, that's why the EDL packages haven't changed in a while.

Suggesting that @Kranoner and @NFound left the Axon 7 Scene because I was getting donations is far from reality. Kranoner left this forums because he no longer uses this device, his son was using it and he was really disappointed by how other developers were not sharing their work, and he decided to not stopping by here any more. NFound left the Axon 7 scene since he replaced his device by a new Nubia and asked to close his own threads in the Axon 7 forums. On the other hand, I created these EDL packages well after those roms were created and after all the donation hype about them. And again, I never received or asked for any donation.

The EDL packages are used by newbies. It is the fist stop for many that later learn how to use TWRP, flash modules, solve their own problems, etc. I use them as a fast way to recover my phone when my experiments go wrong.

Hi everyone! Thanks a ton for this rom. It's amazing. I ran into a problem today. I tried updating Magisk to 17.0 and now the phone is boot looping. Can I fix it without re-flashing everything?

Update: I was able to solve it by flashing the latest Magisk Uninstaller and then re-flashing Magisk 17.0
When updating Magisk, there is a chance of having bootloops. The reason is not related to the rom or the new Magisk version. The problem use to be related with the incompatibility of one of the modules you have installed.

The uninstaller is the safest way. I use Magisk Manager for Recovery, this way I can disable modules and enable them one by one, to detect any incompatibility. It is very handy when upgrading Magisk or installing modules that later you discover are causing bootloops.

By the way, Updating to Magisk 17.1 was fine for me, all the modules I have installed seem to be compatible with this new version.

Hi Oki, thanks for all the great work. Your install instructions and tools really simplify trying out various other Oreo roms or treble roms. One quick ask, do you have a flashable zip for B12 Bootstack. I dont know how to extract from the B12 MiFlash folder.
I really liked your custom B12 bootstack with the Boot on screen of ZTE axon 7

Thank you very much for the excellent tutorial, I followed #2.

Where do you guys see if the phone is quick charging or not? I can't find it anywhere. The only way I can tell if the phone is quick charging is by looking at the estimated charge time.

Depending of the ROM, it's true that sometimes we couldn't see a clear message like 'quick charging...' on the lock screen.
But at least you should see the power in Amper, below the message:
<= 500mA is very old charger, or PC USB = slow charge
< 1000mA is old charger = normal charge
<2000mA is quick charge (QC 2)
<3000mA is quick charge (QC3)

PS: please take into consideration that is is operating and consuming power, means it s good to wait few seconds to read accurate value

Yes, you can take this file:

AXON7-Oki_REMIX_B12_BOOTSTACK-Flashable_EDL.zip

It is ONLY my remix of the B12 bootstack WITHOUT any modem file. So if you have the Nougat Bootstack (B32+B10) and Nougat modem, then you should flash the B12 modem for your region. If you already have the B12 bootstack, then you only have to flash this file to gain EDL mode and say bye-bye to DFU when pressing the key combo.

By the way, this pack can be either flashed in TWRP or using MiFlash.

Thanks Oki for providing the B12 Zip file.

Hi Oki, just confirming. If I have B12 Bootstack, I can flash in TWRP or EDL Correct. Not sure what you meant by bye-bye to DFU. Thanks for the Zip file. Much appreciated. It will turn out very useful for me.

Yes, you can either install the zip using TWRP or uncompressing it and use MiFlash in EDL mode.

I say bye DFu since the universal B12 bootstack has problems entering into EDL mode. The bootstack remix I am sharing is free from that "bug".

What did you do to fix it the bug. I currently have a DFU'd A2017G after installing Universal B12 so I am curious as to the remix prevents it.

I did some experiments and I froze it when I found the right combination. The main features of this B12 bootstack are:
  • EDL mode when pressing VolUp and VolDn while rebooting or turning the phone on. In other words, no DFU mode.
  • No Unlocked bootloader message.
  • It is fully compatible with NFound Treble roms and LOS16
By the way, It is the same bootloader from EDL Option 2 in the OP, so you do not need to flash this if you already have flashed EDL option 2.
