Root Boox Note Air 3C
I wonder whether it is possible to root Onyx Boox Note Air 3C? I do not see any post on it.
The output of `cat /proc/cpuinfo` is Code:

You just started one.
Code:
Model: NoteAir3C Finger: Onyx/NoteAir3C/NoteAir3C:11/2023-10-17_09-55_3.5_a37b266eb/2482:user/test-keys Link: http://firmware-us-volc.boox.com/34a441f633e667cf64adaa74dbe0e477/update.upx Size: 1575084503 MD5: 34a441f633e667cf64adaa74dbe0e477 We don't have the strings yet. The easiest would be if you could pull and post this as there have been some changes recently. Code:
adb pull /system/lib64/libota_jni.so I don't see any loaders offhand for that either, but loaders usually cover lots of models. There can be problems with the memory and peripherals like PMIC. You can go to EDL mode and then perform a basic query to get the info we need for loader. Code:
adb reboot edl edl.exe /l |

The decryption is slightly different. See https://github.com/Hagb/decryptBooxU...ent-1805154847
After that, there is no difficulty patching boot partition and flashing via fastboot. Does the root survive after upgrades? Or it might be usually possible to boot the previously patched boot partition then perform a "Direct Install" to the updated boot partition after every upgrade? Thanks. |

No. After an update grab the new boot image. Most problems with Magisk are because somebody flashed a boot image which was not related to the existing boot image.

Anyway, the approach I proposed does not involve "flashing a boot image not related to the existing boot image". I wanted to say that, use `fastboot boot` to boot the system with an old (Magisk-patched) boot image, and use Magisk to install itself on the boot partition. |

Boot images have a kernel, maybe a DTB, usually not a ramdisk.
Recovery images will have a ramdisk. Version conflicts between kernel modules and kernels will prevent them from loading. |

Now let me try to seek a loader for EDL.
I run the python version of EDL without parameter (I am under Debian Linux), which returns Code:
main - Trying with no loader given ... main - Waiting for the device main - Device detected :) sahara - Protocol version: 2, Version supported: 1 main - Mode detected: sahara sahara - Version 0x2 ------------------------ HWID: 0x001b80e100000000 (MSM_ID:0x001b80e1,OEM_ID:0x0000,MODEL_ID:0x0000) CPU detected: "divar" PK_HASH: 0xd40eee56f3194665574109a39267724ae7944134cd53cb767e293d3c40497955bc8a4519ff992b031fadc6355015ac87 Serial: 0x146292ab |

Thanks. It starts to work miraculously (with any of these three loaders). It looks like that this is an A/B device from the result of printgpt. Unfortunately, the OTA update reboots the system automatically (otherwise one can patch boot right after the update), but it seems possible to set the active slot to the "older" one after update, patch the other boot partition of the updated slot, then reboot to the updated and patched slot.

I'm looking at getting one of these, so as of now, can these be rooted? If so, has anyone typed up any instructions yet?

1. Download the ROM that you want to root (usually the one that you are using). 2. Decrypt the ROM (decryptBooxUpdateUpx is already updated for Note Air 3C, thus now the usage is no different from that for other devices). 3. Patch the boot partition. 4. Flash the patched boot partition via fastboot. I am using Linux (and I did not record the procedure), but as far as I see, the usual manual for Windows works as is. |
