How to backup MCU and Stock Android on MTCE unit?

I've searched and searched and searched, but I can't seem to find a clear answer...
I recently purchased an Eonon-branded PX5 Android 8.0 MTCE_WWW unit (which I believe is VERY similar to MTCE_KLD). I really want to start "tinkering" with the unit (Viper4Android, custom ROMs, etc), but I want to make sure I have backups of the stock MCU and stock Android install before I start messing with anything - so that I can always get back to where I started if need be. Unfortunately, I'm having a hard time getting the MCU and Android firmware files from Eonon (still trying though!) - so I want to see if there is any way that I can create backups of the unit myself.
If I root the unit, can I then make full backups of the MCU and Android? Meaning backups that I can use to recover the unit if something goes wrong? If so, what applications should I use to create such backups? I've very familair with Android devices and rooting in general, but I'm used to having and using a custom recovery for stuff like this - but my understanding is that there is no custom recovery for these units (TWRP, CWM, etc).
Can someone please help me out here? I feel comfortable rooting the device via the adb method. But once I have it rooted, how do I create full MCU and Android backups?
Thank you very much!

Hi,
1. Android ROM - use OTG method to get ROM extract.
2. MCU - you can't. Get original MCU or later from forums or vendor.

Thanks for the response... That's what I was afraid of - no way to back up the MCU. Unfrotunately, my unit is an MTCE_WWW (Eonon) and I haven't had much luck finding recent stock MCU's online - and so far, Eonon hasn't cooperated either (what's the big deal??). <sigh>
I'm not familair with the "OTG method" (did a few searches, but what I saw was just custom revoery to OTG device?). I did finally just root it and at least got a full Titantium Pro backup - better than nothing I guess.

Getting started with PX5

Hi all you clever people
I just bought this unit, https://www.aliexpress.com/item/7-I...igation-Sat-Nav-Radio-Player/32772807019.html, and installed in my car.
I have set up a bluetooth connection with my phone and using a hotspot from the phone to give Internet access.
I have a lot of questions, and I have searched this site, but haven't really found clear answers.
First the facts. here are the data from my settings:
Model: px5(1024x600)
Android version: 8.0
Android security patch level: October 5. 2017
Kernel: 4.4.93+
[email protected] #336
px5-userdebug 8.0.0 OPR5.170623.007 eng.htc.20180804
MCU version: MTCE_MX_V2.92.1
Aug 21 2018 20:10:21
CPU: 8 core 64-bit CPU Coretex-A53 @ 1.5G
Memory: 3891 MB
I know I'm asking a lot of questions, it's just a bit confusing to get started in this new world. I have numbered my questions, so it's easier to reference
1) I would like to get hands free phone calls and texting and navigation. I tried Android Auto, and that was very stable, but I couldn't get the phone to work. I assume thats because it's meant to be run on a phone and then mirrored to the head unit. Now I'm trying with Google Assistent, but it's not really stable. At first it worked pretty well, but now it just works as Google Now, so it won't make phone calls for instance. Any advice on what to choose, and how to get it to work?
2) I found this thread about a custom ROM, https://forum.xda-developers.com/an...t/rom-hal9k-rom-3-mtcd-e-head-units-t3847477/, my unit should be compatible for that, right?
3) As far as I understand, I can not go back to the stock ROM, if I install the new ROM. Then I should flash it with my old ROM. But how do I find out the name of my existing ROM? Is it risky to flash a new ROM, or will I always be able to flash back, if something goes wrong?
4) It's a requirement for the Hal9k ROM, that my MCU is upgraded to at least 2.93. I found this thread, https://forum.xda-developers.com/an...asaita-mcu-updates-rockchip-px5-octa-t3575155, but how do I find out if this MCU upgrade is compatible with my MCU?
5) Finally, I installed Tidal app, so I could download playlist for my head unit, but when I start the app and enter my credentials (and they are correct, because I get an error if I enter a wrong password) it just starts up with a black screen with a play icon in the middle, and previous and next symbols, but no menu, except for a hifi menu in the top left corner, where I can choose streaming quality. I will post a picture tomorrow. Does anyone know how to fix that?
Can someone please help me or at least point me in the right direction? I have spent multiple hours searching this site, but right now I'm a bit confused
Kind regards
Allan

Hi! Ok I should be able to answer most of these:
1) If you use the Hal9K 3.1.1 ROM then calling is linked to the phone through Android Assistant, but I haven't got a good solution for SMS at this stage.
2) Yes is is definitely compatible with your unit.
3) Not true, you can definitely go back, just flash a stock ROM. In my case I was sent the ROM by my seller Eonon
4) Your MCU is MX so just find the correct version of that. Check for the MX version here: https://forum.xda-developers.com/an...ent/mod-cs-x-mod-mtcd-e-mcu-firmware-t3816042
5) Not sure, but hopefully the Hal9K rom will help fix that!
Good luck Allan

Thank you very much, it sound like it should be pretty safe to try the Hal9K ROM. I just have a couple of extra questions:
3a) My seller on AliExpress seems to have no clue, when I'm asking for stock ROM. But I should be able to find something close to my Stock ROM, if I don't succeed with Hal9K, right? Something like the Original Android 8.0 MX ROM mentioned in this thread: http://www.androidiani.com/forum/au...ndroid-rockchip-px5-2-4-gb-ram-32-gb-rom.html
4) I found this thread, https://forum.xda-developers.com/an...evelopment/update-media-auto-mtcd-mx-t3828177, with a link to yadi.sk, where I can find a MTCE_MX_V3.00.rar. That should be compatible with my device, right?
I hope you will bare with my ignorance, I'm really trying to get into this

Did you manage to get Tidal working ?

for Android Auto. I'm running the app called `Head Unit Reload` that would turn the Android system as host. essentially it's helper app for `DHU` (Desktop HeadUnit by Google for android auto debugging).
with HUR you can do either wireless Android Auto or USB tethered. This would handle SMS and phone call hands free.
I'm running Hal9K 3.1.1 ROM on my MCUE HK + Car launcher pro as launcher.

MediaTek T906 Tablet(Made in China!!)

Good Evening All(or whatever time it may be there),
I'm new to XDA and Rooting, etc. etc. I purchased a MediaTek T906 Tablet(Made in China!!). After I received it and charged it, the first thing noticed it wasn't allowing some apps to download and install. Keep in mind this is suppose to be Android 9 and 512Gig 8Gig ram device.
Below is what MTK Droid Tool v2.5.3 says about it(and yes I Root it, am fully aware that it voids warranty):
Hardware : MT6582 (MT6797 is Fake!)
Model : T906
Build number : T906_vEN52S2_TB_20191205
Build date UTC : 20191205-085910
Android v : 9.0
Baseband v: MOLY.WR8.W1315.MD.WG.MP.V54, 2018/01/02 15:01
Kernel v : 3.4.67 ([email protected]) (gcc version 4.7 (GCC) ) #1 SMP Thu Dec 5 16:56:01 CST 2019
Too root(successfully)it I used KingoRoot and Got SuperUser Status/Privileges. I did a lot of reading on root and other root apps(to be used in conjunction with). Long story short, I'm trying to get a specific app to download to this tablet and am not sure how to go about it. I did the dump data/cache thing in Play Store and Google Play Services and reboot. Didn't work. Did all the steps before I root the device. I even used Root Essentials Editor to mod the device name and manufacturer, that didn't work. And the time zone is set to right time zone. So, I'm making this post asking for some guidance and/or help on what I can do? Any and all help is greatly appreciated!!

I am in the same situation as the previous poster with the same Version, Kernel, Baseband, Build and my experience with this should be considered at a beginner's level. In researching this and came across a post that indicated that the tablet is not actually Android 9.0 but suspected to be KitKat. Please, if anyone knows how I could get this setup with Android Oreo, I would be grateful.

Hi guys,
just got the tablet too, it also seems to me it has this config:
- MT6582
- 1GB RAM
- 16GB Storage
- 1280 * 800, 7.19" display
- Android 4.4
Not sure what options there are, but I hope there are some newer Android builds that would work on this?
I'm following

So far....
I have been successful in rooting my device and hope to find a ROM that will move it up to a level that will allow KODI -Leia to be installed. I will let you know what my findings are. I'm just afraid as I don't want to brick the device.

Hi guys . Same problem. But. Works to me. Go in accounts remove account. then try loggin again.
uncheck all boxes. Unynchronize the two options in the account. Agenda and contacts. Deselect the check options. If it doesn't work restart and turn off the wifi. then rewire. Do it again. good luck

A brother in distress
I've got the exact same issue with my T906 Mediatek. I downloaded the Root app (Thanks!) and kept trying to get the things to load and run. I'm specifically having the issue with Alexa app. I can find it but I get that the app isn't compatible. It runs on my Samsung phone that's running A9.0. It keeps saying the app is already installed, yet it isn't . I went into the Play Store and Play Services apps and deleted the updates and caches as suggested on YouTube. No difference. I'm sort of at a "What Now!?" POINT.
Any help would be appreciated.
Be safe out there and for goodness sake, wear your masks until this crap is beat.
The REAL OldGeezer

you can't upgrade generic android devices until version 9. Android 9 seperates the drivers with the treble abstraction layer allowing you keep the drivers and upgrade the rest. The T906 has android 5.11. If you run CM lite scan you will see a huge Opera beta file that is always 3 times your storage. This is how they fake the RAM and ROM sizes. If you take off the back and look at the board you will ussually see printed on the board 1GB ram 16GB rom. They have also faked the CPU by using the ROM for the upspec version with better camera, screen resolution and CPU which uses the same drivers. Thus these are also falsely reported. Sadly Google no longer supports android 5 for things like Google sheets so your apps will soon stop upgrading. I love this machine because the screen size makes it cheap for 50 USD

Help to get ROM image to restore same model
I have the same model but when trying to get root access managed to brick it. I have got SP Flash working and managed to get some T906 firmware on it so I get the Mediatek logo and battery charging symbol on screen however the boot options i.e. Fastboot etc just gives an error message when selecting any of them.
I've got a development background but new to Android and scatter files but is it possible for anyone on this thread with the exact same model to help get back to a working system? I assume there is a way to back it all up using SP Flash ?

hi everyone are in the same problem boot error !!!
how to solve it I have tried in all ways but I find myself as soon as I turn it on boot error !!!! you can not even go into recovery?
Help!!!

These manufacturers need to be found and dealt with cause they are robbing customers. They are giving fake specifications. They need to be sued asap.

I got a Mediatek tablet and try put it in recovery mode and now I got black screen with blue bar with SIM and Chinese Characters. Any way to fix it

Hello guys.
I have a different problem with my T906. It works fine and it is fast and reliable but I had problems downloading apps from the Google Play Store. When I checked it said that the Device is not certified under the Play Protect Certification. I remembered that it came without the Google Play app and I installed from another APK store (apkmirror.com) and it installed without issues. I've tried to download another Google Play app but can't find the correct match for my version and OS (64-bit - Android 8.1).
Any help will be truly appreciated.

I've just created a dump of this tablet with flash tool, maybe you can try to revive yours

MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

Btw I'd welcome any kind of rom that would make this device more usable

MTCE PX6 Android 10 - How to root?

Hi Folks,
I just bought a new device and the seller was nice enough (doh!) to install Android 10 on it. The known way to root up to Android 9 on PX5 and PX6 devices[1] would work here too it seems, at least with minor modifications. I guess the partitions layout, fs-overlay and... stuff... did change a bit, but it was rather straight-forward to implement nevertheless. Enabling ADB over WIFI, adb connect, adb shell remount / and /system rw, moving old su, pushing new su, su --install, pushing SuperSU.apk, correcting permissions, reboot and the system bugs about "app might be for an older version of android, it might not work correctly" and right, nothing root related works. It is like all root requests end in a nirvana and no error messages are generated.
So my guess would be that just a newer su-binary or newer SuperSU.apk (or both) it might just work. I know chainfire left the supersu-team but I am unsure about the implications. Advice here? What about Magisk? I really don't care, I just need root for some apps and general tinkering here and there. Any help appreciated.
regards

EDIT: here is a rooting tool for px6 https://github.com/KswCarProject/KswRooting
Were you able to figure this out? I just bought a px6 android 10 unit since it was a decent bit cheaper than the ones advertising android 9. https://www.aliexpress.com/item/4001090563068.html?spm=a2g0s.9042311.0.0.398a4c4dP5ASrt
Ideally I would like to downgrade to either the Malaysk or Hal9k_ pie roms until a cleanded and optimized android 10 rom is released.

That's basically the same recipe for rooting PX* on Android 9, but crappier implemented (overwrites stuff without creating a backup first). It is no tool, it is just some adb commands gobbled together in a DOS/Windows batch-file, accompanied by Windows-adb-binaries and an arm64 su-binary. Nothing I need. Nothing I don't already have. The su-binary is even identical to the one shipped with the rooting-package for Android 9. The one thing I do need is missing: superuser.apk that actually works on Android 10. Or how does one manage root-access for apps afterwards? At least the guy claims his "package" works on Android 10, so that might be an indication that the su-binary is sane and sound, one thing I can scratch from the bucketlist to get root.
Really weird mix of stuff. No idea if the guy is trustworthy, but mixing the adb-binaries in looks... weird.

Figure what out? And at least for me, I don't hunt for cheap, I hunt for good support. That's why I payed almost 400€ for a PX6 device, just to get better support.

Same here. I asked the seller if he can provide an Android 9 firmware for my device and I am sure he will provide it. Then I can see if I go Malaysk again or stay stock for the moment.

Hello. I own Ownice Android 10, MTCP-OLS-PX6. After all, isn't there a valid rooting method so far?

Question Firmware Upgrade - Joying JFW-UQD11N4G

Feel like I'm missing something obvious - what is the firmware upgrade process on for the JFW-UQD11N4G?
11.6" 1080P UIS7862 head unit.
I've downloaded the latest ZIP from Joying, tried to use the update app, tried to update via settings and saved as "update.zip" in the filesystem root, but that failed.
Any ideas?

I've found this which suggests it needs to be done via USB stick
Wondering if you can do it by downloading/extracting the ZIP on the head unit itself.

You need to post full details of the head unit, System information /MCU version.

Yes, you can. Unizp the firmware to a empty USB-stick and simply insert the usb-stick into the unit. It will recognize the firmware and start the update.
Next time please read the Joying blog where you downloaded the firmware. That exactly describes this process and which firmware is suitable for your hardware (This has to do with sometimes deviating resolutions like for Tesla like units)
That recovery mode is only necessary in case you soft-bricked your unit.

The instructions aren't actually on the page with the download. They were on a different blog page.
My question is, is it possible to do without USB stick/drive since I've downloaded the firmware update directly to the headunit? I guess not.

No, that is indeed not possible. It checks for an update on connected mass storage. usb-stick, sd-card via reader, usb-disk, etc.
