[Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels, ] q2n:
Great to see this, many thanks!

Might the guide be made a little more clear by incorporating the Note section into item 5., something like:

5. Terminal Ops​

Go to Advanced > Terminal, and do the following:​

a. Disable encryption​

Type: multidisabler​

If lines appear complaining about 'vendor free space left on device, will attempt to resize vendor' and it asks to, deny it permission and run multidisabler again! (Type: multidisabler) Will see "Finished." when done.​

​

b. Check that disabling encryption was successful​

Type: cat vendor/etc/fstab.qcom | grep ice​

Lines returned should read "encryptable=ice" not "forceencrypt=ice"​

However, if just the userdata line contains "encryptable=ice", that may be sufficient. If any problems with forced encryption, it may be necessary to manually edit the above fstab.qcom file to replace other instances of "forceencrypt=ice" with "encryptable=ice".​

​

c. Check that auto-restoration of stock recovery was successfully disabled​

Type: ls system/recovery-from-boot.p​

If that filename is listed, manually rename it as follows:​

Type: mv system/recovery-from-boot.p system/recovery-from-boot.p.bak​

Paths are not fully qualified so if used, please correct as needed. (Sorry, don't have access to that phone ATM to check.)

With feedback from the community, some uncertainties can be eliminated and the narrative shortened.

I have a phone that reads:

The RMM is always prenormal and has been for months. The SIM is in, all accounts logged in, phone actively being used. RMM state does not change, so only official firmware can be flashed. Is it even possible to change RMM status at this point?

Your bootloader is locked and you cant unlock or use the twrp since o=you are on v9 bootloader and only v1-7 are unlockable

so just flash N960U1 firmware without twrp

[Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels, ] NextDroid:
@afaneh92 Thanks for the guide and TWRP build!

After following steps 1-3, I flashed @klabit87's kernel and Magisk v25.2.

Upon doing so, both archives produced errors, so I extracted boot.img from the stock AP tarball (PDA ver. SCV40KDS1CVK1) and flashed it, as the terminal output requested:

(Klabit)
Failed to unpack ramdisk

(Magisk)
Please install Magisk on an unmodified boot image

I found that flashing boot.img from TWRP didn't work, but if I created a boot.img.tar from it and flashed it with @jrkruse's modded Odin v3.14, klabit's kernel and Magisk flash successfully.

Any idea why this happened?

All problems are solved now, but I'm just curious :-)

hi @afaneh92 where to edit this

To disable encryption manually:

You need to replace forceencrypt=ice with encryptable=ice only in userdata line (maybe rest lines) in vendor/etc/fstab.qcom

To avoid stock recovery restoration manually:

Rename system/recovery-from-boot.p to recovery-from-boot.p.bak

[Walmart Onn Tablets General] 2384298423:
Attempting to root a ONN device that hasn't gotten a guide posted for it might be a bit of a pain if your a beginner.

Rooting might require you to make your own scatter file using wwrMTK and dump the files from your device yourself using SP Flash Tool which might be a bit hard for beginners to understand how to do so.​

Flashing images (.img) from untrusted sources.

Other people's images or images from untrusted sites could contain malicious modifications to the image that could harm or brick your device so be careful and make you trust the site or person that uploaded the image file.​

The risk of installing malicious software.

Most of the software like SP Flash Tool or wwrMTK mostly don't have a official source to get them so you risk installing tempered or malicious versions of the software which may harm your device or the device running the software.​

TWRP or a custom rom might not be available.

Unofficial builds can take some time to make and build so they might not be available for your device model as of yet so if you just want to install TWRP or a custom rom onto your device it might not be available so check your device model and check if there's a build for it on this forum.​

Rooting isn't as simple as getting the official firmware files.

If you want to use the Magisk method you have keep note that there is no site to download the firmware files officially also it's not on ONN's official website so the firmware can be modified so it's best to get your own firmware files straight from your device to patch with Magisk.​

Hi all! Android noob looking for suggestions.

Manufacturer: Mediawave PC (now Techland PC)

Hardware Model: MW22-A32

Current OS: 4.4.4

Chipset: Rockchip RK3288 (supposedly capable of Android 8.1)

Rooted with SuperSU

Purchased this 22" touch display off eBay and wanted to load an app that requires Android 6 or higher. The manufacturer does not offer an update package for this device and indicated what I have was a special build for a single project that is now likely being refreshed and hardware liquidated. Tech Support indicated I needed to simply buy a NEW device that already has the OS updated.

I would like to think we can update to a newer version of OS, but I have no idea where to start. I checked a few online videos, but they seemed to point to pre-packaged OS bundles from tech enthusiasts for specific mass market tablet models.

Is an upgrade like this possible without having device specific files/firmware? If so, can you point me to a guide or walkthrough for how to do this as an Android novice? Thank you!
