Root for Note Air 2?
I'm curious if anyone has attempted to root their Note Air 2. I'm guessing that the process would be similar to what others have described for other Onyx devices on this forum. I wondered if rooting the Note Air 2 would even be worth the effort, but I can see a couple of possibilities.
If anyone has experience or suggestions, please pass them on. |

If you have ADB working, please try this: (Sorry if I've asked this already.)
Code:
C:\>adb shell grep Hardware /proc/cpuinfo If it's the same (or close), you can use EDL mode to download and subsequently modify the boot image. |

What I get is Qualcomm Technologies, Inc BENGAL
Not sure how close that is! |

Huh? It seems that's a code name for the new Snapdragon 662
There's a 660 driver here https://github.com/bkerler/Loaders/t...alcomm/factory Not sure how compatible that is. |

I’ve never worked with EDL mode before. Do you know of some kind of step-by-step guide as to how I’d root my device this way? I assume it involves Magisk and getting a boot image!

Rule #1: There is no need to write anything to flash. You can run a boot image that is not in flash, so hold off writing anything.
Rule #2: If you've got the space, make a full backup on your desktop, then you're bomb-proof. Do you have ADB working? Have you used UsbView.exe (presuming that you are running Windows? Linux is actually easier with lsusb.) Step #1: Determine if you can get to EDL. This does no harm but you will have to do a LONG power press to restore usage. Code:
C:\>adb reboot edl Does UsbView.exe show VID/PID 05c6/9008? That's EDL mode. If you want you can use my UsbLog.exe which is found on my website up a level, down to the Windows section. It's quite handy to figure out where all the Windows "bongs" are coming from. |

I have ADB working on Mac and have ample room on my Mac to back up my Note Air 2. I set up ADB on my Windows VM, but I haven't been able to get Windows to see my Note Air 2 yet. That keeps me from using USBView. There is probably a Mac alternative out there. I tried adb reboot edl. It goes the voodoo-land route. I was able to reboot it into normal mode before too long. That's where things are as of now. |

The Mac is fine. Stick with that and skip the VM stuff.
You can run "lsusb -v" on the command line and look for the 9008=good, 900e=not good. If you have that you can follow the instructions here for install: https://github.com/bkerler/edl Code:
python edl.py --loader=try-that-660-file.bin --memory=emmc python edl.py print-gpt --memory=emmc python edl.py r boot boot.img --memory=emmc |

Yeah, but you have to do that when you're in EDL mode!

Oops! Here's the EDL mode result. Looks like I have the 9008 option...

Looks good. Now try to install and run that software above. If you run it with no arguments it should? tell you what driver it wants, I believe and tries to load it if you have downloaded all the drivers. You can try with the explicit driver path as in the first line. Once you have a driver, subsequent commands do not need anything to do with that unless you do a reset and then go back to EDL (when you do have to load the driver).
Your ultimate goal is to retrieve boot.img, install Magisk, let it modify boot.img, then fastboot that image so you have a low-risk trial. Last edited by Renate; 11-22-2021 at 09:15 PM. |

Time for me to call it a day, so I’ll install and run that software tomorrow! Thanks again!

Sure, give it a go. EDL mode, "python edl.py" or "edl.py" or "edl" or whatever works.
I don't know if your install installed the drivers too. The message that edl will tell you. If you have no drivers, at least download that 660 driver and explicitly reference it. If "print-gpt" works, try "r" As long as you stay away from other commands you should be safe. |
