Yes. I did each time when I apply update.zip and/or dmcu.img .

Actually bluetooth name/password are always empty after each system reboot. I filled out the name and password, but after the next reboot they become empty again. This indicates the MD725 is not recognized by system. No matter which rom/mcu I apply they stay empty.

My MD725 was working well with PX3 board on Android 5.1.1 and 7.1.2.
[MTCD Software Development] imran0487:
Im no talking about the bluetooth settings menu..im talking about the factory settings menu..there you can actually select your bluetooth modules..
[MTCD Software Development] yves31:
Of course, I did mean changing bluetooth module MD725/BC5/BC6/... in factory settings each time when I apply update.zip and/or dmcu.img. I have tried at least 8 different Oreo versions and dmcu images, and each time MD725/BC5/BC6/... were alternated with system reboot.

Those who do not have MD725 module problem will not notice empty BT name/password. I have empty BT name each time in update/reboot. This is an indication that my MD725 module was not able to be activated by any of the Oreo versions.
[MTCD Software Development] macoloco:
Maybe the problem is that your px3 doesnt support Oreo...because is made for PX5 boards...just maybe, i think
[MTCD Software Development] imran0487:
did you try this version of android Oreo?

[MTCD Software Development] yves31:
Yes, I did. MD725 did not work either with this rom.

---------- Post added at 07:00 AM ---------- Previous post was at 06:55 AM ----------

I used to have PX3 on mainboard and the PX3 coreboard got replaced by PX5. Bluetooth module is on mainboard, not on coreboard, therefore not replaced.
[MTCD Software Development] macoloco:
Ok...i misunderstood your early post. I think you were talking about Android 5 and 7....and i taked for granted you were on PX3 platfrom. I thought that PX5 works only with 6 and 8 android flavours...

What mcu are you using right now? My erisin is a ES3646U with LM MCU but i saw other erisin radios with different MCU (GA,MX or so....)

i just re-read your post and notice about MD725 version....You were right i am on MD725 v1 , i think

I've read about this module on XDA and someone who upgrade to Oreo and found BT not working took the solution of soldering a MD725 v2 to get BT working again. So i suppose V1 must be the problematic one, not V2

I thought my HU was old with v1 and thats why kumaria Oreo rom doesnt work with my BT module af first glance....maybe LM dumped rom has any driver or so.
[MTCD Software Development] yves31:
This makes sense. My current mcu is HA_v2.88, and I have tried LM_v2.88, LM_v2.81, KD_v2.41 and many more. None of them showed any impact on my MD725 module.
[MTCD Software Development] macoloco:
I dont know if all mcu are cross compatible..but mcu seems not affect to bt comunication between px5 and mainboard.

I say that because i have tried LM 2.88 with two different android version

LM 2.88 with kumarai oreo version (2017/11 i think)...bt module doesnt wake up

Only when i flashed WG20180625 (dont remember exact date veraion) Bt wake up (no empty name and pin in bt settings) and started to work (discover, pair, etc)

Bit of an amature here but is it possible to put android 8.0 oreo on my unit with and update.img?

I am currently on xtrons android 6.0.1 with a px-5 unit running mcu GS

I have looked at this process and it looks a bit tricky.

I also dont have access to a laptop at the moment hence the reason i ask for the .img file so i can load direct.
[MTCD Software Development] typos1:
Change the launcher then

No, for Oreo you neeed update.zip, theres a thread on how to upgrade to Oreo.
[MTCD Software Development] theXeffect:
kinda new to car stereo android is there another rom I can use for Xtrons android 8 TE103AP? Or can I run all roms?
[MTCD Software Development] z3nith66:
Guys is there a clear post on updating from 6 to 8?

There are so many files everywhere, I don't even know which is the best method or what files I should use. In the Drive link there are more files than required I think. Are you all using the Kumarai version?
[MTCD Software Development] maus05:
It's so simple to update from 6 to 8 if you have two sd card slots (the slot named gps or map should be bootable).

You can install every available rom. It doesn't matter if you use kgl, hct, ha, gs, Malaysk or any other rom. Every rom should work on any px5 unit (2gb or 4gb).

Look in the Malaysk Oreo thread for instructions. Do all steps from 1 to 4 and when you are at step 5, choose your favorite rom and put the update.zip on the second sd card. Then go further with step 6 and so on. I tested it on my Erisin (kgl) head unit with most of them.

But, and that is very important, do not install a different type of mcu on your unit if you don't know what you do!
[MTCD Software Development] yves31:
If your bluetooth module is MD725, upgrade to Android 8 may rend it nonfunctional.

Basically you need to: 1) prepare a bootable SD card with Android 8 recovery, 2) boot your unit with the SD card, and 3) flash the new system to your unit in the recovery. Follow instructions of one post with its files and do not mix files from different posts.

Your current system is Android 6 and its recovery is incompatible with Android 8. That's why you need to start with a SD card to boot into Android 8.

I made some progress on MD725 type 2 bluetooth module and it can show BT name and PIN code now. My phone can also see car BT host, however, cannot pair with it. I am convinced that a new driver is required to get it work. For the record here is what I have done:

1) Root the system and 2) Copy gocsdk in /system/bin folder to make a new file, sdsdk, in the same folder, and fix its permission (to 755).

MD725 type 1 uses gocsdk to activate BT and type 2 uses sdsdk. With the changes I forced type 2 to use gocsdk and BT module was recognized, however failed to pair.

I did not find gocsdk in early versions of Oreo (e.g. 2107-12-19), so they might not be able to support any MD725 modules (type 1 or 2). That's why you need to get a newer version such as WG20180625 to make BT work.
[MTCD Software Development] z3nith66:
Thanks!

Where can I see what bluetooth module I have?
[MTCD Software Development] dj.shauny.g:
I dont understand much about the process...is it just the same as a .img but with a .zip?

Xtrons are a seller only and they sell different head units from different manufacturers, so you need to state your MCU and processor type for us to be able to identify your unit.
[MTCD Software Development] belfastbob:
Hi,

I have an Xtrons unit which I have had for over 18 months, I would really like to update the firmware to something newer, my units details are as follows:-

Model ICE/HU/PB76FSFAP-B, Android 6, Kernel Version 3.10.0 rocky@htcr930, Build Number PX5 userdebug 6.0.1 MXC891, MCU Version MTCD_gs_v2.38_1

Would I be able to use this rom to upgrade my device.

Thanks in advance
[MTCD Software Development] typos1:

[IMG="firmware MCU"]https://s8.postimg.cc/ihducjm6d/1_Dasaita_HA2106-_V840-8_Build_MCU.jpg[/IMG]

Is it safe to do rooting my device in this way, with yours files, and whether it is better Magisk or SuperSU?
[MTCD Software Development] dj.shauny.g:
Ok.

With the .zip should i extract the files onto the root of the sd card? Or just leave them in the folder?
[MTCD Software Development] iRcKenny:
If you read with attention the provided instruction you understand to simply copy the update.zip file on blank sd card root.

Have you read the thread????
[MTCD Software Development] dj.shauny.g:
Yes. But the update.zip is a folder, not a file. So thats why i ask should i unzip and copy the contents of the folder onto the root of the sd card....or leave the folder on it.

The thread does not explain very well, especially when some of us are not as experienced. Why do you think there is people asking for help?
[MTCD Software Development] iRcKenny:
All Oreo updates are in .7z file format, you need use 7zip utility to extract the archive; On archive you find a update.zip file.

You need use this update.zip as it is, simply copy on sd card root. No need other actions, simple.

And for "not exprerienced people" in my honest opinion, before trying this stuffs they need to be very well documented or a probably s*h*i*t happens during operation.

I'm ok for helping people, but people need to apply a little before asking same questions on well aswered replies on discussion thread.

In your case, if decompress update.zip was needed for sure you should read "you need decompress update.zip file and copy the files on..."; clear?

For this i dont want seem rude or unpolite, but all we have a brain, so use it ;)

Hi everyone,

finally able to read all the posts. i want to thank everyone that has been sharing their knowledge and helping others.

Like some members here, my HU is PX5 with 2GB RAM Android 6.0 that i purchased back in November 2017 from Shannon (Aliexpress). It has 3 USB drives but does not have an SD Card slot. I can get to android Recovery.

https://www.aliexpress.com/item/Das...r-Toyota-Camry-2012-2014-USA/32833487512.html

(but Android 6)

1) Can I upgrade to Android 8 through android Recovery? or it can only be done with SD Card or OJG?

2) If i need add an SD Card Slot, which ribbon cable do i need to get for SD Card Reader from Spark (https://www.sparkfun.com/products/544) and my HU (see attached picture)? and which ribbon port on the board do i connect the ribbon to?

[IMG="HU Board"]https://dl.xda-developers.com/thumbs/4/4/2/5/3/3/2/4425332.jpg[/IMG]

i think member, [MENTION=454491]sibeng[/MENTION] has similar HU for a different car but boards look the same. He was able to upgrade it to Android 8.0. I would love to know how he got his HU to upgrade to Android 8 Recovery.

I own Witson's multimedia.

I had installed android 6.0.1 (MTCE_MX2_V2.96_1):

Following the instructions from the site, I made the update at 8.0.0. Everything is OK. except for Bluetooth connections (in factory default settings by MD725 diff). I also tried BT SD968 without success.

The media does not detect the phone, and the phone does not detect the media.

I have a Witson media W2-B5762 (4GB + 32GB + 1.6GHz) with installed Android version 6.0.1 and mcu version (MTCE_MX_V2.96).

I installed your latest ROM for 8.0.0 (update) everything works OK. except BT.

I got the A2DP icon, and the BT icon for the phone did not. Pairing is not possible.

In the setting, it simply does not see the mob.tel (neither Smsung7 nor Huawie).

I believe that it is a version of mcu (MX4).

Please send me your mcu version.

[MTCD Software Development] Seicane-Misery:
Hi,

if your car headunit with an android 8 the bt module is not working but only with an android 6, it means that the bt module driver of your car headunit was not included with the newer antdriod 8 fw version.. because otherwise how would your bt works on andriod 6 without any problem then? right?

I had in the past also such bt as yours now 725 and had no problem with connecting at all.

Now I have that mentioned sd 968 chip and also have no problem with my bt connecting at all.. understood why I asked you now? they may say what they like to say but in the practice must should been seen working.

I meant by that: build in to your car headunit mobo ofcourse.

ps: my car audio shop mate which he (is the owner of his company!!) sold also chinese car headunit's and stuff too but have no witson or was he ever seller of witson car headunit, that's why I wrote strange!

I already knew that, all those names were invented themselves because these things (android car headunits) are came from the same manufacturers in china, with a bit different on look and this and that etc.
[MTCD Software Development] typos1:
All head units do not come from the same manufacturer. There are lots of different types of Android headunit, these forums deal with MTC headunits which do not all come form the same manufacturer - there are about 20 manufacturers of MTC units, they all use the same SoM/coreboard, but with slightly different motherboard designs, hence the different MCUs, only the SoM/coreboards come from the same manufacturer.

[MTCD Software Development] typos1:
Please DO NOT spread mis-information on the forum, your comment is complete non-sese.

Witson is a seller, it sells units as "their own" when they are in fact made by ShenZhen GESHI Electronics And Technology CO.LTD or Shenzhen Mai Xin Da Technology Co. Ltd

Joyous is a manufacturer selling under the brand name "Joying", they do not make units using the MTCD/E platform any longer.

The idea that there is only one manufacturer of Android head units is FALSE.

For a list of MTC head unit manufacturers is available in the HuiFei wiki.
