Vitson PX5 Android 6.0.1 with BT module MD 725 upgrade to 8.0 Oreo, definitely BT can not be paired with a mob. phone.

---------- Post added at 07:54 PM ---------- Previous post was at 07:19 PM ----------

Witson
[MTCD Software Development] radoslavsto:
greeting

Where can this be seen which type of module 725 (type 1, type2)?
[MTCD Software Development] xLeviNx:
Search Rado, there’s a huge thread on how to determine which module version you have...
[MTCD Software Development] EmporioLTU:
Hi, followed everything. After 6 step I cant access recovery. Have any ideas?
[MTCD Software Development] EmporioLTU:
Interesting, repeated everything again ant it worked! Everything is running, thank you very much!
[MTCD Software Development] reverendhtc:
I had the same trouble accessing recovery.

You need to know the correct way to enter recovery for your device.

On my Joying J0509 (with swapped PX5 board) I googled and found out I had to press the volume control in whilst turning on the car's ignition at the same time. Then hold the button pressed for 5 seconds, release and press it again.

It worked and then I was able to install the zip package.

Good luck.

My Bluetooth also does not work any more.

I am now planning to install the Joying version of Oreo for PX5 devices in a hope that Bluetooth will work again.
[MTCD Software Development] typos1:
BT is not working on Oreo one with of the 2 versions of the MD725 BT chip (cant remember which it is, the beginning of [MENTION=5092263]Hal9k_[/MENTION]'s ROM thread explains which one).

Joying do not make MTCD/E units anymore, so you cannot install a Joying ROM on an RK3368/PX5 SoM, you will likely brick your device.
[MTCD Software Development] reverendhtc:
Thanks for the heads-up. I'll hold off on the install. I assumed that as Joying have an update for their PX5 devices that it would work for me.

I'll have a look at the Hal thread as you suggest.

I upgraded to Android 8 to resolve the Google Maps hanging issue which has worked, now I have introduced a new issue.

I will install whatever ROM that is available where Maps and Bluetooth work. More reading to be done.
[MTCD Software Development] typos1:
A lot of people assume all devices with RK3368/PX5 SoMs are the same, but no, that would be a bit like expecting an HP and a Dell laptop each with the same Intel processor to use the same firmware etc. Or a Samsung smartphone and a Sony smartphone each using the same processor to use the same ROM (pre project treble).

If you have the MD725 version that works youll be fine, if not you can buy a different BT module, there are a few threads on this in the forums.
[MTCD Software Development] reverendhtc:
Looking at the BT module swap it would appear that another issue arises .... that of the serious reduction in WiFi speed when Bluetooth is connected.

I think I will remove this head unit and swap it for another.

It is a shame as the unit works otherwise, I guess that is the price of the constant changing world of technology.

Thanks for your help.

EDIT: Unless a BT USB module can be used??
[MTCD Software Development] typos1:
The problem is that Oreo cant find a particular library to make BT work, if it could it would be fine, people have tried to add the library and direct Android to it but so far it hasnt worked.

A USB BT has been tried on both MTCD/E and MTCB/C units but I cant remember the results.
[MTCD Software Development] reverendhtc:
I'll do some reading on the BT USB method.

Also I'm going to search to see if Bluetooth and Google Maps work on Android 7. If so, I will just downgrade to that version of Android for my MTCD unit.
[MTCD Software Development] typos1:
Theres no Android 7 for RK3368/PX5 SoMs, its 6 or 8, I m afraid.
[MTCD Software Development] reverendhtc:
We'll that's just great :) So here's hoping those cleverer than me will be able to either get a reliable BT hardware solution or an Android 8 software solution, with no caveats.

I have subscribed to all those threads.

Thanks for your help.
[MTCD Software Development] typos1:
No probs, but did you check which version on the MD725 you have ? You didnt say it was that version I just assumed.
[MTCD Software Development] reverendhtc:
Actually I haven't checked which version I have. Sorry to ask here but how do I check?

Open up the unit and read off of the board or is there a software method?

Thanks.
[MTCD Software Development] typos1:
At the beginning of [MENTION=5092263]Hal9k_[/MENTION]'s Oreo ROM thread he explains how, you install a terminal emulator and type some code, it will tell what type you have, he also says which type works with Oreo..
[MTCD Software Development] reverendhtc:
Okay I'll do that but as BT is not working I expect I have the version 2 module.

I have also seen some more issues today.

1. When returning to the car and switching on the ignition, Wi-Fi is switched off, even when it was on before leaving the car.

2. The image from my reverse camera works, but sometimes freezes (image stops moving)

Anyone else getting these issues?

The only good thing that has come out of my android 6 to 8 upgrade is that maps is not crashing before, but now there are three new problems :(

This unit is close to going in the bin.
[MTCD Software Development] marchnz:
If not already, upgrade MCU. For BT issue, it is possible to swapout type 2 for type 1.
[MTCD Software Development] typos1:
Try updating the MCU to sort the reverse cam problem.

I have heard of the wifi issue before, the MCU may help this, there are some threads about it in the forum, maybe search for them and see what solutions people have used ?
[MTCD Software Development] reverendhtc:
I just upgraded the MCU to MTCE_HA_V3.06.

The Wi-Fi problem is fixed. The reverse camera issue seems to be resolved as well (I will monitor it over the next few days).

Also nice to see the power off timeout is now available again in settings.

Thanks for the advice, now I'm just praying drivers get released for the Bluetooth to work again.
[MTCD Software Development] typos1:
Check out [MENTION=4974080]marchnz[/MENTION]'s post above.
[MTCD Software Development] reverendhtc:
I see all the talk about Bluetooth and the various fixes, but In have decided to revert back to android 6.

Can someone confirm the correct method to downgrade.

I am planning to use the Rockchip Create Upgrade Disk Tool as in this video

https://youtu.be/34GSX5aId8Q

But not use the android 8 image, just use the android 6 image.

Would that work or am I going to have a problem?
[MTCD Software Development] typos1:
Flash [MENTION=5092263]Hal9k_[/MENTION]'s Oreo ROM, then use his downgrade method, its much easier.
[MTCD Software Development] reverendhtc:
In post #106 of Hal9k's rom thread he answers a similar question saying that the stock rom can be reinstalled using the update function from the settings menu and using an update file on a sd card.

The stock android 8 also has the update function in the settings so I guess it should work the same?
[MTCD Software Development] typos1:
I think he modifies things a bit, to be on the safe side, flash his Oreo then follow his downgrade procedure.
[MTCD Software Development] reverendhtc:
Okay understood. I can see in post #1 of that thread under the section if android 6 is installed that the method I describe above can be used to revert back to android 6.

At the moment I don't see the need to install Hal9k's rom.

Could you let me know the post # with the specific downgrade procedure as I am having trouble finding it.
[MTCD Software Development] typos1:
I sorry I dont know the exact procedure as I ve never done it, if it was me I would flash his ROM and then downgrade, just in case.
[MTCD Software Development] kebul:
Where can I find the Rom version 201711 for LM. In my Unit also does not work bluetooth. I tried all the ways to run bluetooth.
[MTCD Software Development] faulkner23:
Ok I've downloaded the files and created a bootable sdupdate when I delete the sdupdate.img do I copy the files from the update.zip into the micro SD

[MTCD Software Development] Blueqq2:
Hello, I have a problem with the radio, the radio turns on for a while and then goes out, sometimes it works longer.

The second thing is that sometimes it won't start and you need to press the reset button to enable.

It happened because I changed the start screen wallpaper in factory settings, saved and restarted, and after restarting it does not turn on. After what time it turned on and this problem appeared

after trying to update the system such an error

[MTCD Software Development] MAhtc:
Is there a detailed sdcard update guideline ? Sorry most threads have been vague I have read.
[MTCD Software Development] typos1:
What, a normal update or a Marshmallow to Oreo update ?
[MTCD Software Development] MAhtc:
Going to android 8 or higher from Android 4.4
[MTCD Software Development] typos1:
Thats not possible - there are no MTCD/E units that have Android 4.4.
[MTCD Software Development] MAhtc:
Sorry lol, 6.1
[MTCD Software Development] MAhtc:
The radio specs
[MTCD Software Development] typos1:
Just follow the guide in the first post of [MENTION=5092263]Hal9k_[/MENTION]'s Oreo ROM thread.
[MTCD Software Development] marchnz:
Thanks, but just select language 2 in the .ini
[MTCD Software Development] ikerg:
But....did you have a soft brick? Or could you reflash android 6?

[MTCD Software Development] marchnz:
Hmmmm...I got black screen no boot, just like the previous version of SDCard tool. Ill try making a bootable android 6 card that we know works to validate. I had previously asked for someone to test the SDCard maker on PX5 android 6 and that person said it worked, so hoping...
[MTCD Software Development] iJo09:
Same here, black screen and can hear cpu working, rebooted itself 3 times and then dead unit. Detached and reattached power connector and the unit is working again, like nothing happened
[MTCD Software Development] typos1:
Ah, I see.

Hmm, strange.
[MTCD Software Development] kumarai:
Hi

Thanks for dumping firmware 8

It works on PX5 RAM 2 Gb

https://www.instagram.com/p/Be6cromluvx/?r=wa1

when you collect the firmware, replace the loader
[MTCD Software Development] iJo09:
How did you succeeded to flash the firmware? Can you tell us what to do step by step? Thanks!
[MTCD Software Development] typos1:
You Russians have done it ?? ! Woohoo !

Thats a real group effort then - [MENTION=7329495]xdamember2[/MENTION] from the US sends his SoM to [MENTION=4974080]marchnz[/MENTION] in NZ who extracts the image and [MENTION=6738895]kumarai[/MENTION] from RU gets it working by replacing the loader !

(I didnt do much other than talk, lol)

---------- Post added at 11:33 PM ---------- Previous post was at 11:27 PM ----------

Replace the bootloader with the one in [MENTION=6738895]kumarai[/MENTION]'s post.
[MTCD Software Development] iJo09:
How do I replace the bootloader? I used the 3GB sdupdate.img for the bootable sd card
[MTCD Software Development] typos1:
You have to do before you make the update image.

You could try MTCD ROM builder and see if it works, theres a thread in the MTCD forum.
[MTCD Software Development] zhangyi0402:
Will someone upload a new omg with the new bootloader?
[MTCD Software Development] marchnz:
HI Kumarai,

Thanks for your comments.

Which loader? How did you repack? Are you saying use PX5 Android 6, extract and copy new system into it?

Also, when I used the SD CARD tool, it works with PX5 Android 6, but not my created SDUPDATE.IMG.

Can you give steps?
[MTCD Software Development] marchnz:
Very easy.
[MTCD Software Development] typos1:
I thought he meant the bootloader and to change the one in the image you uploaded for the one in his post.

[MENTION=6738895]kumarai[/MENTION], can you give us a link to the ROM you flashed on your unit ?
[MTCD Software Development] marchnz:
For my package, I extracted the bootloader from [backup.img]. Ive just recreated it fully using the imgrepackerRK, retesting...
[MTCD Software Development] marchnz:
Ah - I see the RAR. OK, that bootloader appears to be the same as the one I used, extracted from [BACKUP.IMG]. So, Im doing something wrong.

Im hoping [MENTION=6738895]kumarai[/MENTION] whill share steps to create.
[MTCD Software Development] ikerg:
The bootloader that refers kumarai is a bootloader extracted from android8 or from android6?

Or the bootloader was different between the ota I published and the one you extracted?

Enviado desde mi SM-G950F mediante Tapatalk
[MTCD Software Development] marchnz:
1. Looks to be 8

2. I didnt use OTA, all extract from ROM, dont think your ZIP contains bootloader.
[MTCD Software Development] ikerg:
By the way...i published new release of ota update

Enviado desde mi SM-G950F mediante Tapatalk
[MTCD Software Development] iJo09:
I have extracted the full image of "sdupdate.img" and hex-checked the two bootloader (the one from kumarai and the one included in the image), but they are identical!

So what do you mean by changing the bootloader? It's already perfect in the image!
[MTCD Software Development] Wadzio:
If I'm not wrong I dont think so they are the same:
[MTCD Software Development] iJo09:
The Image you find in the Demo folder of PX5 Upgrade tool is a 4.4.4 KitKat firmware, that has nothing to do with 8.0 Oreo
[MTCD Software Development] Wadzio:
Correct me if I' wrong:

copy MiniLoaderAll.bin & parameter.txt from @kumarai to 'RKPX5 OS Configuration tool\Android\Image'

copy necessary *.img files from @marchnz dump to 'RKPX5 OS Configuration tool\Android\Image'

build sdupdate.img

Is it wrong procedure ?
[MTCD Software Development] iJo09:
Here's the thing: sdupdate.img is already built and downloadable from Drive
[MTCD Software Development] Wadzio:
Ok, sorry for confusion. I overlooked "MTCD-SHARED->Test-Firmware->sdupdate.img"
[MTCD Software Development] iJo09:
Tried SD Boot mode in Rockchip Upgrade Disk tool. Still a no-go.

How did [MENTION=6738895]kumarai[/MENTION] flash his unit?
[MTCD Software Development] typos1:
I havent been able to login to 4pda.ru few a few years (it keeps saying it will send me an email and to login from there, but I never get it) I bet theres a copy on there already !
[MTCD Software Development] Flockrock:
Can't load the firmware update with RKPX5 OS Configuration tool V1.0.1.9 on a SDcard. Format error.

Anyone know a solution?

Edit: Just works with SDHC cards in FAT32
[MTCD Software Development] iJo09:
Please tell us if it works on your unit! Thank you
[MTCD Software Development] Sorazy:
Please tell us how you made that!

Or can you give us the img you used?
[MTCD Software Development] KoTiX2:
I beleive that the right procedure should be to ignore the prebuild sdupdate.img and instead use the dumped files from here

Replace the bin and paameter files using the one provided by kumarai:

https://xdaforums.com/attachment.php?attachmentid=4412762&d=1518045450

Rebuild the image using afptool and rkimagemaker

I will try my self when i get back home from work.
[MTCD Software Development] iJo09:
The bootloader .bin and parameter file from dump are identical to the ones provided by kumarai

P.S. Tried to use Afptool, it fails (ParseParamFile:no found firmware version FAILED)

P.S. 2: Looks like I was missing some files! Now it builds update.img but without many partitions (cache, frp, metadata, oem, security, vendor)
[MTCD Software Development] Flockrock:
I made a mistake and now I have the same problem you already had. How do I make a bootable card?

EDIT: Nevermind.

Just booted after keeping it running for like ten minutes.
[MTCD Software Development] Wadzio:
One interesting thing, when I made a build my sdupdate.img has 2GB not 3 :confused: (I included *.img files what is in package-file). Question: rest is necessary?
[MTCD Software Development] iJo09:
image.cfg and package-file are "married", so all the images that are in image.cfg (under RKAF) CAN and NEED to be inserted in package-file with their respective path

Try to add an image in package-file that is not also in image.cfg, Afptool will crash instantaneously

P.S. frp, metadata and security are mostly blank files (filled with zeros) so they can be ignored
[MTCD Software Development] iJo09:
Still a no-go, even with an image that I built myself (size around 3GB). The headunit display stays solid black, despite "display_lcd=1" in sd_boot_config. 1 minute and then it reboots itself three times. Then the unit is dead until I disconnect and reconnect the power cable.

It seems that it's trying to read the file but fails because of timeout.

I even tried to boot in recovery and select "apply system image from sd card". It cannot find update.img even if it's there.

I really think that the only method to have Oreo is to boot in loader mode and flash the firmware
[MTCD Software Development] typos1:
Or to get hold of [MENTION=6738895]kumarai[/MENTION]'s image.
[MTCD Software Development] KoTiX2:
I built the image, i tried the update method wiping userdata and it started the update but it gave me back an error about FRP partition is invalid.

So i will try the sdboot method.

It just take time to create the card and flash the 3gb of the firmware ;)
[MTCD Software Development] iJo09:
So you tried the image in recovery?
[MTCD Software Development] KoTiX2:
I created the sdupdate.img and i renamed it update.img so i can put it on USB and let it be recognized by the unit as a system update.

The update has started but it gave me back that frp partition error.

Now i'm creating the sdboot card but i'm facing errors there too: E: failed to mount /mnt/external_sd (No such device)

:(

Anyway, just to have a comparison, the image i created is 3.241.079.256 byte
[MTCD Software Development] iJo09:
Are you trying to use bootable sd card inside of recovery? That is not correct. You have to restart the unit and then it will -theoretically- start flashing the firmware

That depends on what partitions you have included in your image
[MTCD Software Development] KoTiX2:
Of course i'm starting the unit from poweroff i know what a recovery card is ;)

I know this too, but i'm using the kumarai files as i said earlier.

i just don't understand why it give me error on external_sd not mounted if it's starting the boot from it...

Anybody have used the sdboot tool on px5 before?
[MTCD Software Development] iJo09:
external_sd is the GPS card slot, but try to put it into the other slot just in case

As far as I can tell, at least your unit boots with the bootable sd card! Mine won’t do anything
[MTCD Software Development] Wadzio:
Probably a stupid idea, but we may have to replace SDBoot.bin with the MiniLoaderAll.bin file. Although there isUSE_FW_LOADER = true in the config.ini file, what can we understand that the loader from the firmware should be used :confused:
[MTCD Software Development] iJo09:
BINGO! I think you are right!

Tried to change SDBoot.bin with the bootloader file (renamed SDBoot) and that has changed the version displayed in SD Firmware Tool program!

Also the USE_FW_LOADER must be blank (as described in chinese) with non-3288 devices (PX5 is RK33xx)!

P.S. Tried using the bootloader file as SDBoot. Still nothing
[MTCD Software Development] KoTiX2:
After trying the sdboot card my unit is stucked at bootlogo now.

I will try first to load the android 6.0 firmware with sdboot card, then i'll play more with oreo.
[MTCD Software Development] iJo09:
Where do you find the Android 6 complete firmware? Not the normal update.img
[MTCD Software Development] KoTiX2:
sdboot.bin is the bootloader that make sdcard bootable. you cannot rename the miniloader and make it act as a SDcard bootloader. i guess it will simply not boot from sdcard (feel free to correct me).

Talking back about my tests: i recovered my unit hot swapping the sdcards... i could probably try to enter in recovery mode too but i was using the sdboot card so i just used it beacuse i know it give me error and it enter in recovery mode.

Once in recovery i replaced the sdbootcard with the one with standard update.img and i selected the option to flash system update from sdcard.

All run smooth till the end and now i have my unit back running android 6.

I'm done for tonight, i'll wait more inputs from kumarai tomorrow ;)
[MTCD Software Development] typos1:
You could try registering on 4pda.ru, I bet the update i already in their PX5 thread.
[MTCD Software Development] KoTiX2:
I'm already registers there since some years ;)
[MTCD Software Development] marchnz:
If it is, I couldnt find it. I suspect that the upgrade can only be achieved via OTG as the SDCARD tool version for Android 6 isnt compatible with Oreo/8.

Ive suggested a method to create your own OTG jig without using an MTCD mainboard, using pins to connect to the SOM, a powersupply (although suspect USB power is sufficient) and a male USB cable. Ikerg is testing it.
[MTCD Software Development] KoTiX2:
I'd like to know if somebody have at least used the sdcard tool with an android 6 image successfully.

I'd like to know if this tool has been proved to work with mct mages and it's not only for stt (joying)
[MTCD Software Development] marchnz:
Yes, I have used the SDCARD tool (in my share) to create an Android 6 recovery and successfully applied it. Note that earlier versions of this tool would not apply Android 6 on MTCD.....hence my quest to recover via OTG, which I succeeded in :)
[MTCD Software Development] typos1:
Tried looking for it on there ? As I said Ive not been able to access my account for a while

Hmm. Dam, pity [MENTION=6738895]kumarai[/MENTION] has gone so quiet.
[MTCD Software Development] marchnz:
Yes, looked there in MTCD Px5 Android 8 thread. Chrome does a pretty good translate. There are no upgrade images, other than what ikerg provided. I see some requests for it though.

Yes, crickets....wonder...
[MTCD Software Development] typos1:
Strange youd have thought hed have released it on there, maybe theres another thread ? I ll have a google, I wont be able to download it if I find it, for reasons I ve already stated, but one of you guys could.

[MTCD Software Development] marchnz:
From your Instagram pictures, used OTG, correct?

Members here looking for software update/SDCard and I we have been trying to see if a software method will work.
[MTCD Software Development] Oberbergler:
In the 4pda Android 6 thread kumarai wrote that he will publish the updating instructions within the next days.
[MTCD Software Development] Wadzio:
And few post later he wrote: "Full Oreo Roma backup is under the link htps://drive.google.c...TdRzl6fjkkb-YUB-KpTViW. Who can quickly collect the" (google translate). Link point to @marchnz google drive.

So I think he did it using OTG not sdcard.

Edit:

"Who can quickly collect the" was translated from "может кто быстрее соберет". My knowledge of russian language tells me "You can quickly download"

Are you sure is the same person?

magnitolog.ru its company also. You can see that they earn money (https://magnitolog.ru/stranitsy/pricing). Therefore, we should consider whether they share knowledge with others
[MTCD Software Development] Chocoman:
"может кто быстрее соберет" - it's mean "maybe someone can built image faster".

It's the same person, and he's working for now on that.
