YT9216BJ (MT8227L) Head Unit Root Question - Android Head-Units

So I bought this head unit and i am looking to root it. I'm accustomed to XDA and rooting and I also found the russian forum that disscusses these head units but I'm lost. It seems mine is newer(?) or more up to date than im seeing. It says android 10.1(it seems to be really 9) and is API 27.
Things i see seem to be giving root for my device but downgrading it. Is there any assistance I can receive on this? Attached some screenshots.

Okay so having the newer Android shouldn't be a problem as your unit type and MCU are right for modding.
I've successfully modded a similar unit only a couple of weeks back. Backup your current ROM by exporting the full memory dump, just in case of brick.
You start with installing TWRP recovery. Normally only version 3.0.2 will work. If not, try newer then older versions. One of them will stick.
After TWRP it's an easy ride. Install SuperSU v2.79 and if it doesn't work, try newer then older versions.
Now you can install Viper4Android. I suggest you stick to version 2.5.0.
Now just configure everything you need.

Ok thanks for the reply. I did some searching today on the forum after reading your post but all I see is flashing a whole new rom.
Is there a guide to just install TWRP to my current stock rom(I actually like it) and then the usual SuperSU to obtain root priveleges?

I just posted this this guide that provides custom firmware and lots of improvements to YT9216BJ, that includes TWRP, SuperSU and much much more. You can of course stick with the stock firmware but there is an option of making your unit much more appealing

need help for rooting

I'm new to here. I have an Asus tf101-x1 (the BlackFriday version from Bestbuy), it says B90KASxx on the box, and the firmware is US_epad-8.5.5.9-20110816. I tried to use Razorclaw to root my device, but failed, it tells me that it lacks some file needed, I need some help for rooting it. After reading some threads, some members say that it works for their B90, is it an issue of my firmware version? if it is, what version do I need to root it? or is there another way around to root it?
Your question was answer in the other thread.

I don't think you can for now. Razorclaw needs the firmware to be at 8.6.5.19 (or .18), and you can't get there through OTA updates. B90 can't get a custom recovery unless its rooted, so you can't flash the rom.

Quick question about the HU in a truck I bought.

I have this head unit that came installed in a truck I purchased;
http://www.amazon.com/gp/product/B00WG1PKJC?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
It runs 4.2.2 and looks to be new. My question would be, Is there anything I can do with it? It runs pretty decent and supports most, if not all of the apps I use. I would like to update it to a custom ROM but it's unclear if I can or not.
Thanks ahead of time!

Yes, this is correct. Completely read the first post, paying attention to upgrading to a pre-rooted 4.4 ROM and which MCU to install.
4.3.14-7-10-650201-150527
This is what my system is reporting what version MCU it has. How do I identify what I need to upgrade?
Anybody? All I'm looking for is if I can install 4.4.4.
Thank you.
I'm still confused on which unit this is. Any other way to find out other than mcu?
I really would like to upgrade this thing. I HATE the hard coded buttons at the bottom of the screen. They take up nearly half of it.
The upgrade method should be the same as with the rest most likely (copy the ROM to the root of an SD card, put it in the GPS slot, get into recovery and it should prompt you to upgrade). You should be able to flash any ROM that's made for your CPU, regardless of which MCU you have/need. I haven't flashed the MCU on mine since I see no reason to do it (if it ain't broke...) but the ROM and MCU can be flashed independently so no need to worry about the other if only one is a problem.
About the launcher, that's just an APK so you should be able to install a new launcher even without flashing a new ROM.

New to rooting

Hey, all im new into the world of rooting and i have a couple of question regarding rooting
I have a device Huawei p smart FIG-LX1 with android 9 and i would like to root it but the guides on the internet always says something different, so im kinda tangled with this whole thing, i found this post https://forum.xda-developers.com/huawei-p-smart/how-to/how-to-root-huawei-p-smart-fig-lx1-t3752705
but i dont understand it
Hello Panieldakula
You want to root your Huawei P Smart (FIG-LX1 with Android 9) but it seems difficult to do, right?
Have you tried a one button rooting software? It did not work or why do you want to do it manually?
These "one button rooting" solutions are usually fake/malware or only work up to Android M.
If there is any tool to flash stock firmware like there are for Samsung and Qualcomm devices maybe it's possible to flash a signed TWRP to recovery and then use Magisk to root.
I have done this to other devices in the past although only for devices that came with Lollipop or Marshmallow. ButI have searched for such tool and didn't find anything for P Smart, maybe someone that has more experience with Huawei device can point to some solution.

Thank you lfom,
I hope you are right and someone can point the new guys to the right direction.
Similar to Panieldakula I am new to rooting and the instructions given by Veromax seem not to be too user-friendly.
Well, if no other manual exist I might go through the instructions line for line.
However, there are probably easier general manual I could start with, or?
Do you or does someone have a recommendation?
Thanks.
AFAIK the only way to root and install TWRP so far is by using the unlock code that only works with an earlier version of MIUI 8.1.

Downgrade from

Hallo everybody.
I have a tab s3 with Android 9, firmware T825XXU3CTA1, and I hate it, too slow.
I would like to downgrade it to Android 8 or, if possible, even better to 7.
I boughy it via Amazon Italy
Which firmware should I download and, if I may, where can I?
I wouldn't like to root, but if needed I can do it.
See enclosed for more details.
Thank you and have a nice day.

Nokia 5 TA-1053, original 7.1.1, got TWRP Recovery adapted by Can Xin from Chinese 7to forum, but stuck now

hey there,
just a quick recap:
The phone is still on Android 7.1.1, I"ve got a script with ADB from 7to Forum through 4pda.to, got the custom TWRP working, but after getting root through flashing magisk, it got stuck on boot. After I got the official 7.1.1 zip, it is back on official recovery and I gave up... (Link to 4pda, which I got my inital files from - it is a link to google translate, so you could read, what it is all about
The forum here on xda-developers for Nokia 5 is really messed up and there is no real guide or any help which could help me out, I don"t know any valid source of official ROMs, there are no tools - nothing.
I planned to get on Android 9 with ROOT through MAGISK, so I"ve got a unlocked bootloader and wanted just update to Android 9, so I could install MAGISK through TWRP.
but none of that worked, I got only the unlocked Bootloader....
maybe someone could please help, I just don"t know where to start now - I have some knowledge about Android, because every single smartphone of mine got rooted (HTC EVO 3D, SAMSUNG S5, HTC MI8), as I love AdAway and Viper4Android, but this phone for a family member got me started..... This phone is brand new, never used, got it from the grandmother of my girlfriend, wanted to get it to work and give it to someone else in need of a smartphone, but I got stuck...
Thanks it advance
I've managed to update it to pie, with some obscure errors, but it works flawlessly, but I'm on 6.12 now, want to update it to 6.19, but it doesn't work through the recovery, but I'm on it.
Maybe I will write a little tutorial after all, for someone, who has also those problems like me - it is getting harder and harder to get things done on older devices...
