Do this: Code:
adb shell lsmod Magisk'ing a boot image pulled from your device will not break anything. Just keep a copy of your original boot image on your desktop. Thanks for the question. I hadn't realized how overboard everybody has gotten with kernel modules! |

Thank you. It comes right in time. I intend to root my tab ultra (b&w) in a try to lower or disable processes and services to increase battery life. But i got some questions.
Its this tuc image functional for tab ultra? If not where i can find a stable version? How i make a system backup and restore it if thing go wrong? How can i update after rooting it? |

If you have EDL working, the most bomb-proof backup is to use EDL to take a raw copy of your entire flash memory. Yes, this is big and slow if you have 64 or 128 GB. It also is very ungainly if you want some portion of the backup after you have saved it as one lump. It may not even restore to a replacement device (because of key generation for userdata encryption). But restored on the exact same device it will take you back to exactly where you were.
I've done this on my Poke3 a few times. I save a new backup, restore an old backup, hit "Last read" and it pops to the page in the book where I was a few months back. I restore the new backup, hit "Last read" and it's right back on my current book. Ah, that's a different question. Onyx has mostly been using full updates so it does not presume what you have on your device, besides checking that you are not rolling back to an earlier version. If your update is over 1 GB it probably is a full update. If it is smaller it could be an incremental update that will keep some parts of the old version. If you have modified things behind Onyx's back there may be collisions. For the simple Magisk case, usually the entire boot image is replaced anyway so you only have to deal with your device being unrooted. For rolling back versions you will need to modify updater-script in the update. |

Thanks for this guide. This works for the new Tab Ultra C Pro, just had to use a different loader (Qualcomm sdm855).

@petedux Great to know it works on the pro! where did you find the loader for the sdm855? I’m looking to root my pro as well.

Mmm, just a heads up.
Somebody with a Tab10CPro is having a problem with decrypting updates as there have been some changes in strings for DeBooxUpd. (I'm confused too as to what the heck a Tab10CPro is anyway.) |

It is “Onyx Boox Tab Ultra C Pro”, it is getting really messy with all these “new” devices

Edit: I get it. This is one of those "Russian" ones. Still, has anybody decoded an update for the "normal" TabUltraCPro? If you go to EDL mode and then use an EDL client (either the Python one or mine in the sig) the first thing it will tell you is that info. The following is for mine. Code:
adb reboot edl edl.exe /l Serial: <not really that secret, but don't quote> HWID: <maybe 000a50e1-00000000> Hash: <maybe ec70ff124179a138...> Last edited by Renate; 11-09-2023 at 10:57 AM. |

Any recommendations on image backups and restoring from them? I've been searching and it seems like there is no custom recovery for Boox ![]() |
