I retract this, it seems like there is a weird issue with this that occurs that creates a bootloop.

Remember to use these procedures at your own risk! getting a bootloop on this device is hard to recover from. Since we can only boot two modes using hardware keys: normal boot mode and EDL mode. If you get a bootloop, you have to recover through EDL mode
Yes, thats old, not relevant for Max3. You're best off just taking a dump of the current system.img and tweaking that. Or root with magisk and tweak individual files in root.
if someone can provide me with dumps of a few files that would be very helpful.

https://anonfiles.com/P7T6K764n9/emmcdl_exe
https://anonfiles.com/KeT8K06ene/prog_emmc_firehose_8953_ddr_mbn

download those two files... turn off your device by holding the power button for about 10 seconds, with the device off, hold the home button while plugging in to your computer's usb port. Keep holding home until the blue light turns off, and then it will stay off or sometimes a red light will blink. let go of home

inside windows device manager, you should see the usb device under "ports" as qualcomm 9008

wherever those files are downloaded to, open that folder in a command prompt.
i would like the following dumps:

emmcdl.exe -p COM7 ***(or your COM port here) -f prog_emmc_firehose_8953_ddr.mbn -d system -o system.img

emmcdl.exe -p COM7 -f prog_emmc_firehose_8953_ddr.mbn -d boot -o boot.img

emmcdl.exe -p COM7 -f prog_emmc_firehose_8953_ddr.mbn -d userdata -o userdata.img

the last one will take the longest but possibly most important, you can run these after a factory reset from the settings menu, or not. just disclaimer that if not then technically i have access to potentially sensitive data. I would prefer the userdata after a factory reset anyway
How do you get into EDL mode?

I installed work email and it asked me to encrypt it. After that happened, it went into a boot loop and now i get Decryption failed, reset tablet, but i get error: /data not found or not mounted. So i cannot factory reset it.


Do the steps above allow me to restore it?

Thanks.

These two links are dead. I have found these, but i am not sure if they are correct:

Thanks.
yes those files are correct. you can try wiping /userdata in edl mode.. only problem is that I am unsure if onyx puts proprietary files in /data that are required for boot. its worth a shot though.
also that sounds like a major bug, I would inform onyx. its a pain, but you can also do a return
Hello.
Finally, it's possible to root Max3? Somebody has rooted the device?

What is the method to use? If bootloop there's a way to reset to fabric status?

Thanks
Sorry about a lot of questions but is a very expensive device and I wouldn't like to brick this
Finally?... This root came out 2 days after the first Max 3 were received by the public. "Already" might describe it better.

I am not sure how to answer your questions in any other way than how they are already answered in the original post
Sorry but I'm so noob rooting this kind of devices

In first post
"This means that we take our modified recovery.img and flash it to the recovery partition, then when we boot into recovery mode, Magisk automatically boots into a rooted system."

Where is de recovery.img?

I can run The others steps ... adb reboot, fastboot ... etc... but I can't locate the recovery img

Thanks
