Is there any working method to temporary root this phone? - Redmi Note 9 Pro Max Questions & Answers

So, i don't want any custom ROM or anything, i just need to access some app's hidden files (Steam), more specifically, i need to edit some XML files that are stuck somewhere in /data.
KingoRoot doesn't work, the APK just says Root Failed, and tells me to try the desktop variant, the desktop variant doesn't work either.
I would've rooted it, but i don't want to unlock the bootloader and lose my files. So i am at a bit of a loss here.

Htc ruu option

Has anyone thought, that when you run the RUU, it does make a temp folder for the contents..that maybe you can root the device from the RUU files and give the binaries of superuser to the OS?
Such as go to the folder, read the files needed, add the superuser binaries and apk, then continue with the ruu process which will auto apply the root?
I don't think that would work, I think if you mess with any of the files it breaks the signature and won't load on an s-on device. I think others have tried some variations of that and no dice.

[Q] Problem with superuser/superSU/rooting

This being my first post a HI EVERYBODY is in order.
On with the show.
So, I managed to unlock my bootloader via htcdev website, i slapped on the cwm recovery and managed to put a custom rom on my cell.
The rom in question is the jellyking, works fine, everything is great.
PROBLEM:
although ive tried several cm10 roms i liked jellyking the most but on all of them i had troubles getting root.
what happens is that i download es file manager, set it to give me root and mount system as RW, popup says that the preinstalled (with rom) superuser app granted those rights and that everything should be superb, but I couldnt copy files from my sd to lets say /system/media (wanted to change my bootanim) it says file copy failed, only once i did manage to copy a file but i dont know how.
The question:
when i put a custom rom, do i need to reapply the famous root.zip or maybe install busybox as my first app or maybe flash over the existing superuser app the superSU app which seems to update the root binaries sucessfully.
BOTTOM LINE:
What is the exact (if any) procedure that I need to follow to get perm root access (copy rights) to my own phone, each and every reboot.
Thanks in advance for all Your insights,
Humbly,

[Q] Delete Superuser

Hi Experts,
i am posting after a very long time.
So i have an Orange version of HTC one X which i had rooted .
i however didnt install a custom ROM.
Now since i use my phone to access office emails, the team wanted me to unroot my device.
i checked on google and the easiest way was to delete some SU files from bin folder, and delete Superuser.apk.
i did delete the files, however was unable to delete the .apk file.
i relocked my bootloader.
i still get error messages from my office security system that my system is rooted.
i really want your step by step help to remove the SU without losing any data, or factory reste.. HELP!!
ok tried everythng .. cant get this to work.. guys i need this real bad.. my email access has been barred.
Though mu bootloader says Relocked, and root checker says tht i do no have root, i am unable to get rid of Super SU, and an app installed by my office (Mass360) says that i cannot receice email as my device is rooted

experienced embedded developer with general platform questions

In other systems I have worked with there are sometimes ways to boot from a file other than the NVRAM that you ordinarily operate from. For some reason people
like to call this the ROM, even though it is writable.
I have an old tablet that has a recovery mode that is only a Chinese menu. I have seen a translation so I know what the items are but none of them
are helpful for re-flashing or booting from a file.
I have been able to connect the tablet using adb and run the shell, and I can get it into fastboot mode but the instructions for "unlocking" the boot loader do
not work so I am stuck with a fastboot prompt on the tablet with no way to proceed. I was able to upload a short file but not the TWRP (I did find one for this
phone). The failure was permission.
My questions:
I have rooted this phone using kingroot and promptly decided that was unsafe and did a full reset to manufacturer. But I am still trying to root. I suppose that the
rooting programs must have to run an exploit, perhaps a buffer overflow thing, but at any rate some series of commands to Android that cause elevation to
be accomplished. Where do I find the exploit documented in order to just do it manually?
Can I extract the su binary from the TWRP and jam it in there? Probably not but I thought I'd ask. Is the su binary in there just an ordinary program unless it
has a file bit set that elevates it?
What exactly is meant by the phrase "unlock the bootloader"? Can I unlock the bootloader manually in the adb shell?
Can I kingroot again and find an su binary, rename it, uninstall kingroot, rename it again? I don't suppose that re-named binary would survive a reflash?
How can I flash this tablet? The tools don't quite work. Even if I can back it up I can't reflash. Best would be the ability to boot a file separate from the ROM. I
read somewhere that sometimes after the flash the phone boots the old ROM once. How can that be true, and if it is true what does that say about the way
those images are actually stored and used?

Temporary Root to Access data/ Directory - is it possible?

Hi there,
I'm needing root access but I don't want to permanently have my device rooted - is there a way to achieve this or am I on the road to nowhere? Ideally I'd get access, download the files and then reboot back to normal.
Running standard 9 Pie in my Pixel 2 XL.
Many thanks!
I may be wrong so anyone with more knowledge please chime in. In order to root on this phone you need to modify the boot.img and to do that you need an unlocked bootloader. Is yours unlocked? If not I think you may be dead in the water.
If you're meaning the OEM Unlocking in the developer settings then yes I can unlock that. I know some networks block it from being toggled but I bought my phone unlocked so isn't tied to any provider so I'm think it may be possible?
That button gives you the ability to unlock the bootloader via fastboot, not an instant unlock.

You shouldn't need root to copy files from the /data partition. You can simply use a file manager for that. You need root however to copy files to the /data partition.
A little more detail on what you're trying to accomplish here may be useful.
I have tried a few file explorers and none of them have access to data/. It's true I only want to read from and not write to any of the files and/or directories but I don't even seem to be able to get that.
I'm wanting to copy the key file from the WhatsApp folder.
I think it's in data/data/com.whatsapp/key
If the file managers can't see it, use ADB and pull it from /data.
