Update MCU & DownGrade MCU ?

Hi friends!
I currently have
android rario ISUDAR
px3-userdebug 7.1.2 NHG47L eng.hct20180
MTCE_XRC_V2.80_1
2Gb/ 16Gb
1 - Can I upgrade to MTCE_GS_V3.07? (recommended by Chinese vendor). How do I identify compatible MCUs?
2 - If the update fails, can I reinstall MTCE_XRC_V2.80_1 MCU?
If there is any tutorial reporting on MCUs, you will be welcome.
Thank you very much

Hi again
I have read everything and the compatible MCUs are clear to me.
I am clear that I can update from MTCE_XRC_V2.80_1 to MTCE_GS_V3.07, but I am not sure if after updating I can return to the MTCE_XRC_V2.80_1 version simply by doing an MCU update
Thank you very much again

Yes, you can 'downgrade' and return to factory MCU code. Is there a specific issue with the current version XRC MCU?

My problem is:
https://forum.xda-developers.com/an...ad-units-general/help-swc-50-bottons-t3831607
I wrote to seller and he told me update MCU to MTCE_GS_V3.07. For this reason I have needed information about MCU´s, although I'm not sure about updating the MCU, I'm afraid of break the radio.
Thank you very much

One last question...
My unit head is 800x480, Do I need add mcu.ext file to install MTCE_GS_V3.07 or install MTCE_XRC_V2.80_1? Both MCU rar/zip file aren´t add dmcu.ext in:

Today I have updated MCU to MTCE_GS_V3.07 without dmcu.ext file and it has created problem in screen resolution. After it, I have installed from option update mcu recovery the file dmcu.ext and resolution screen works fine.
MCU MTCE_GS_V3.07 not worked fine in my head unit. It show error "unmatch" on screen and play a beep sound in short interval time.
Afer it, I have re-updated MCU to my original version MTCE_XRC_V2.80_1 with dmcu.ext and then, my head unit worked fine ( without SWC 100% )

I had a factory in PX5 rom MTCE_XRC_V2.80_1 dedicated to Alfa Romeo 159.
I decided to make an update and uploaded not to my version of the equipment.
The screen resolution has changed and the radio did not work well.
I was able to return to MTCE_XRC_V2.80_1 after searching the forum and change the resolution to 800x480 by dmcu.ext
After returning to the old version, there was no button illumination and you can only turn the volume down with the volume knob.
I was able to set the backlight but I do not know how to turn the volume back on with the knob.

Have you tried setting "knob" type in factory settings? Knob controls the volume button analog type, you might have to try a couple of settings until correct.
Backlight is also set in factory settings, try that too.
Good work reading through forums to find the information, listing out the steps you took to help others help you without guessing

With few contributors you're going to need to read and figure out for yourself.
The answers are found in the forums. Be prepared to read, anf have a go. You could then decide to write up your findings here or disappear, like most do after getting what they came here for.....

I'm trying to figure it out but afraid I might brick my unit. I'm looking into Hal9k Mod v4 for MTCD/E but I can find these requirement in my head unit.
The model starts with px5 (rk3368) or px6 (rk3399) or px30 (rk3326_mid)
My unit only shows px5 but not the rk*****. Is it the same with my system?

Your unit is an MTCD/E so have a number of paid and free options. (refer MCU type in images) it's also a PX5 SOM.

Already done updating to Android 8 and Hal9K Mod 3.1. Now I want to update my MCU firmware MTCD_KGL_V2.36_2. I reade somewhere that MTCD and MTCE are cross compatible. Does it mean I can use mcu update file like MTCE_KGL_V3.10 to my Head unit to update?

Have to ask, why do you want to update your MCU, what's broken?
Only For the billionth time MTCD = MTCE.
For the purpose of those searching (no one will, there's a pattern of new joins, who joined XDA simply to get support and will disappear after getting an answer and don't seem to want to use their own time to understand) and meta crawlers MTCD and MTCE are the same.
The Chinese ostensibly used a different suffix to confuse people.
Got your answer, guess we'll be seeing ya
MTCD = MTCE
MTCE = MTCD
Cheers,
- Bueller.

Ok. Thanks. I watched on youtube in order to update to Android 9 MCU must be MTCE so I'm wondering if my unit is compatible. Also I learned that bluetooth MD725 will not work on Android 7 and above so I think I can't do about that thing.

I watched my local TV channel, it had nothing, much like the youchoobes.
Cool, also covered, md725; Android 8 and 9 are ok, 10 is out. Read first post later

Question Bounty$100 .. Convert Honor magic vs chinese to global

Hi , Supposedly i bought a new fold phone. Tired of samsung monopoly and big fan of mate 20x , i went for magic vs. I got duped by alibaba seller as he stated that he will install global rom ie MagicOs 7.1 bt phone is still on magic OS 7. (android 12)
So anybody who can actually help me convert it to global are welcome. I got it done earlier for my mate 20x but this time honor magic os is still based on huawei's harmony os and its impossible to get proper google integration.
Also i read its easy to root any snapdragon phone with some method(lost post link)
But when i used to do this earlier it was never possible without unlocking bootloader and to the best of my knowledge honor and huawei no longer provide those.
If nothing comes out., i would have to take things into my own hands. Guys please advice me if its possible to root and if yes, are there any guides to port twrp. Also i remember earlier there used to be things like android kitchen, whats new recently. All advices are welcome. People help!!
Apart from this, mods please feel free to move this to appropriate section.

I have the exact same problem. Got a brand new Honor Magic Vs Chinese version, running MagicOS 7.0 & Android 12 . Great hardware, but can't have Google suite put on properly unless upgrade the system to MagicOS 7.1 with Android 13. While there's quasi solutions to use Google apps, via Gspace or others, it's just not the solid experience unless the Google Services Framework can be put on properly. Can't find a way to upgrade the system software still.

wait, magicOS china has gapps on android 13? I'd be interested in buying a chinese honor as well. anyways, this might be what you are searching for I think (if I got the model right): http://www.viprom.cn/list/21931.html

Hi guys, any one managed to do the global Rom flash to their Magic v or Vs?
Or managed to install the Google services on MagicOs 7.0

Global launch is around the corner so its just a matter of time before we will see a global rom. I think the Problem might be the locked bootloader.
And I can not read Chinese but all these firmwares on the linked site seem to be Android 12 Firmwares. We need a MagicOS 7.1 Firmware. Not 7.0.x.x.x.

can you share your device about pick

hello was there any success ?

So if I bought the global version, does that mean that things like Android auto should work?

I purchased the Magic Vs in the UK and it does have Android Auto integrated.
Also, there is full Google integration.

Question Navifly 9863 9" upgrade questions

Hi all, i've brought the unit in subject on 2021, the manufacter ID is 116 and it comes with 9863 processor.
I've attached the HWget_info.zip for a better identification, i've made a backup using the script from @surfer63 (thanks a lot)
The unit works very well (except for the microphone performance, i will try the mic additional setting in the config.txt) and i would lile to maintain to unit up-to-date
The question is if is better to use a factory firmware (from Mekede since i've read that the id 116 refers to them) or use a modded firmware like the mariodantas MD Edition.
The modded firmware is compatible with my unit?
If i want to update usign that firmware i have to add to the usb stick the AllAppUpdate.bin that comes from my backup?
In backup there is no 6316_1.zip which is present for example in the Mekede factory firmware that i've download from their website, is it correct?
Thanks in advance for every hint or answer to my questions

I try the factory firmware from Mekede (the one for 9863 9"), It's working flawless no bugs found so far.
The Mariodantes firmware seems not compatible, any advice for a modded firmware to install?

I found this on the 4pda forum, is it suitable wth my unit?

All firmwares come in two parts. The 6315_1.zip for the uis7862, and the 6316_1.zip for the uis8581a (sc9863a). These are called the kernels for the different CPUs and they are incompatible. @mariodantas version is a uis7862 kernel, so NOT compatible with your uis8581a.
Then we have the AllappUpdate.bin which is the FYT Android apk layer. It is compatible between the uis7862/uis8581a/UIS8141E (SC7731)/sc98531.
The first two ( uis7862 and uis8581a) are Android 10, the last two (UIS8141E (SC7731) and sc98531) are Android 8.1. On the latter two the AllAppUpdate.bon is differently packaged, but actually the same.

Yes, it is compatible but you have to look at the fyt.bluetooth and manufacturer id.

Ok, understand. I check the russian firmware and the rotation and bluetooth setting is identical to my original firmware, but the manufactuter is 1 and mine original is 116.
So i've to change and then rebuild the zip (same password?)
Can i get rid in config.txt for lines about russian customization? or simply replace my original config.txt?
Last question regarding MCU update. It's different from firmware update (kernel and apk layer)? I try to search in mekede website but i don't found anything about MCU downloads

Can i get rid in config.txt for lines about russian customization? => Yes or simply replace my original config.txt? => Yes, also possible
Last question regarding MCU update. It's different from firmware update (kernel and apk layer)? I try to search in mekede website but i don't found anything about MCU downloads => If there is a MCU firmware inside that firmware, remove it before flashing. If this firmware is an MCU firmwre only, don't flash it if you are not certain about the results.

The file list inside the zip. It seems that there is no MCU inside and actually i don't understand why there's two kernels inside (cross compatibility with 7862/8581?).
Just ask about MCU update because i want to maintain up-to-date the unit, but i can't found anything on the Mekede website

About the zips and so on: I explained that in post #4 above.
Mekede so far did not release an MCU update, so you are 100% up-to-date.

You could start with reading post #2 of "General FYT based Spreadtrum uis7862 (unisoc ums512) - Q&A, Mods, tips, firmware". That gives all the info you want. also how to use/tweak a newer Tesla style firmware (like from Joying) to adapt to your unit and flash it.
With regard to your sound issue: Don't cross post. Simply continue in the post of @vitdaika. This not to fragment info over many threads which makes it unusable. I will answer in that thread to keep the info in one place.

You could start with reading post #2 of "General FYT based Spreadtrum uis7862 (unisoc ums512) - Q&A, Mods, tips, firmware". That gives all the info you want. also how to use/tweak a newer Tesla style firmware (like from Joying) to adapt to your unit and flash it.

I found this but I can't find where to disable the internal microphone and use only the external microphone and add other sound settings because there is no config.txt file in the zip.
As I said, my main problem is, for example, when I'm talking to you on the phone, your voice sounds scratchy and bad to me.
I didn't get any feedback from the people I talked to about my own voice, but if turning off the internal microphone helps my microphone quality, I can add it, but I seriously couldn't find how to do it even though I read that post.
ADDED : wait a second, I understand that I will add the config.txt file next to these files, and when this file is flashed, it will replace my config.txt file with the original one. but first I have to backup my original config.txt file and make necessary additions or edits to this file, right? that is, opening an empty config.txt file and adding only the new codes in it will cause the settings to be deleted if there are settings in the original config.txt file.

Nice that you found my repo. That script is to really replace a config.txt inside /oem/app. It is not to be used to "simply" update some settings via a flashable config.txt.
But you really have to search/read more in this forum.
