OKAY

Please tell me where it is best to download img for my device to be uploaded by MASKROM. Preferably A9.

Let me remind you: "PX5 MTCE LM HTC-PX5-REV10 (LPDDR)"

HI

It worked, but only partially.

I used a laptop and WindowsXP 32bit.

My OTG cable (design board from the first photo #937) detected "SOM".

I used the description and the software: "https://xdaforums.com/t/px3-5-otg-no-headunit-mod-recover-or-flash-a-som-with-a-simple-usb -cable.3766892 / post-76224309 "

However, I mistakenly used "Android Tools 2.71" instead of "Rockchip AndroidTool v2.1".

The "firmware upgrade" for "sdupdate-A8-Kumarai.img" was successful.

"Download firmware" went smoothly up to "ftp.img". An error occurred with 35% of the "userdata.img" file. Connecting the device to the computer with the OTG cable is no longer possible (I have tried many times). The device, however, starts up according to the attached photos. Reacts to pressing MUTE, POWER and icons on the screen.

It is impossible to perform MASCROMES. But it may be the fault of too long "male-male" cable. I have to buy another one.

I prepared an SD card as described here "https://xdaforums.com/t/mtcd-e-android-10-upgrade-using-official-free-tools.4123933/" from A9. With this card, at the very beginning, I correctly switched from A8 to A9. I put it in the device. After booting the device, however, the screen is black all the time (I waited for a few minutes). Without a card, it starts as described above.

I am unable to call "Recovery". I have backlit buttons and it is difficult for me to find the right moment to press reset once.

What to do next?

I suspect a not uncommon story for beginners (regardless of age)...

Bricked my MTCD trying to upgrade it and while MCU seems responsive IE Reset and Power button presses result in consistent illumination light flashes, I am unable to get into recovery mode and SD slot, USB ports are unresponsive.

Following this thread I removed SOM

Connected direct to USB via androidTool V2.5.2 and the tweezer hack

(A few false starts but) USB is recognized

androidTool shows 'Found 1 LOADER device'

Can read Chip Info and test device

chip tag 33 33 30 41

Image Chip Flag: -RK330A

But ReadFlasID\ReadCapacity\ReadFlashInfo fail

Get FlashID Fail

and unable to upgrade\write recovery image

Get FlashInfo Start

Get FlashID Fail

RockChipBatchTool has similar errors IE

Get FlashInfo Fail

Have read through this thread a couple of times, but no closer to working out how I get from LOADER to MASKROM modes?

The SOM looks to be an earlier one 'HCT-PX5-REV3'

Perhaps the errors mean I am toast?

Is anyone able to advise or clarify?

Appreciate any thoughts you might have

Information is in the thread. There hasn't been a single unit recovered any differently from what is here. I'm not going to repeat posts ad infinitum.

Alternatively send the unit or SOM to me for assessment and recovery covering return freight. In all the SOM sent, only one has been unrecoverable due to board failure.

@poor_lackey should erase flash first with ROM .img selected. Yes I just repeated a post...
[MTCD Hardware Development] woma1:
HI @marchnz

HI

I read the entire thread carefully. I also read a few other threads in our forum carefully. Threads on a similar topic. I wouldn't bother if I found the information that was right for me. Nowhere did I find the answer to the question: what to do in my situation. I sent a screenshot of the screen after a rescue attempt. Nobody described such a screen. Neither the method from the first posts (directly SOM), nor via USB or SD card, was working anymore. The computer cannot see the device. But it is alive because, as you can see, something appears on the screen. Maybe I should try to connect several times (until I get bored)? USB on mic is not detecting. It's not about drivers. Nothing appears on devices!

Use the go maskrom button under advanced functions.. I used a 12k and 22k resistor and cable is about 20 inches. Mine auto switches back and forth, works great.
[MTCD Hardware Development] poor_lackey:
Thanks, for input, I have tried 'Go Maskrom'

the result is

'Reset Device Start'

'Reset Device Success'

and the usb connection is reset\dropped.

Any options\buttons then deliver popup 'Not found any devices, stop running!'

and the only way to restore the USB connection appears to be unplug > plug with the jumper to gnd in place IE back to square 1.
[MTCD Hardware Development] james73448:
load firmware don't do anything else but erase flash and upgrade flash. If you have success then don't worry about the other buttons,. I get errors to sometime. but erase and upgrade do just fine. I;m using Rkdevtool ver.2.79
[MTCD Hardware Development] poor_lackey:
Thanks, have tried everything and all I see is 'Get FlashInfo Fail' and similar errors from androidTool.

Looks like it's in a box for the foreseeable future.
[MTCD Hardware Development] james73448:
what resistor did you use for the cable and what version rockusb driver?

My first cable was about 3 ft long with a 10 and 20 resistor I'd have to hold a jumper to short contact the whole time.

My second was 3 foot long with a 2.2 and 3.3 resistor, wouldn't even connect.

Third time was a charm 20 inches and 12 k and 20 k resistor,

That was the sweet spot for me it. See's bootloader, I load firmware click erase it switches to mask automatic. then upgrade. I don't have to do anything hardly. Hope this helps.

If your in the states you could mail it to me also, I'm North of Texas.

I have only managed to enter loader mode once in 1 year.... (I have patience, I know haha) I don't know what I'm doing wrong, in maskrom mode it enters perfectly. I have been able to flash the px3 board that I have, in maskrom mode it always gave me the error boot download fail. I am going to buy new resistors and I am going to make some new cables, the radio still does not start and I would like to fix the px5 as well.
[MTCD Hardware Development] poor_lackey:
Apologies for delayed response.

I provide support frequently in a completely unrelated forum and fully understand your scepticism.

Everything has been disclosed, I see no value in non disclosure when seeking support for an issue I can't resolve - it would just waste my time and yours.

1 computer tried, the usb interface is recognized correctly when the tweezer hack mentioned in post #942 is followed. Loader mode is entered and as posted I can read 'Chip Info' and 'test device' but cannot access the flash and ever option results in 'Get FlashID Fail'.

Based on a quick check of unzipped downloads I have tried AndroidTool 2.35, 2.52, rockChip Driver Assist 1.3, 4.8, 5.1.1

I assume either the V3 devices are different from V4\later versions, or I have missed the winning tool\usb driver combo.

It's no longer a priority as purchased a replacement but have an aversion to throwing away good stuff... even more than I hate it when technology beats me, so every hopeful.

And to those that have provided suggestions, thanks for your time and input.

It's greatly appreciated.

Ok so far so good :) som is recognised by pc and just made a dump

Too bad it flashed the recovery but i am not able to install update.zip trough USB

it does not mount anymore

So last question about this

Where to find a proper tutorial to flash android 8 recovery the only tutorials i found are flashing with SD card

none are flashing som directly and they all look different .

(install android 8 rom after installing recovery would likely be the same as installing malaysk rom 6.1 right? )

My goal is to install latest working 8.0 GS rom or malaysk rom if thats possible

If this is the wrong thread my apologies

- Flash kumarai's android 8 with android tool - ok.

- Unzip and flash all partitions in "px5_OREO_Full_13032018-UseToRecoverOrCreateNew.7zip" file -error-

To flash all partitions I did:

Right click and load config file on the download section of android tool

Select "config_16.cfg" (config_8.cfg can not be loaded, it forces to stop the android tool)

click "run" button and get the message: "match device type failed stop running"

Something must be wrong somewhere, but where?
[MTCD Hardware Development] Flying_Hero:
Mentioned update.img file is in the px5_OREO_Full_13032018-UseToRecoverOrCreateNew.7zip file. Unzip this zip first.

In android tool, get the "upgrade" section, click "firmware" and select update.img file from unzipped " px5_OREO_Full_13032018-UseToRecoverOrCreateNew" folder (Or which update.img file you want to flash) and click "upgrade" button, next to the "firmware" button.
[MTCD Hardware Development] sand0rz:
Thanks Flying_Hero, upgrading sdupdate-A8-Kumarai.img is not the problem

the problem is that update.img(actual rom) cant be flashed with a usb stick ( it does not mount )

So how can we flash the unpacked files into the system ( px5_OREO_Full_13032018-UseToRecoverOrCreateNew------->>\Image)
[MTCD Hardware Development] Flying_Hero:
Normally, you can use an Android 6.0 update.img file to upgrade. And then simply insert the som to the head unit back. Everything should be installed. Enjoy your Android 6.0 HU again. :)

But if you want to install Android 8.0 you have to upgrade with sdupdate-A8-Kumarai.img (as you already did),

After flashing sdupdate-A8-Kumarai.img with upgrade section, come back to dowload section. Right clik on the list, click "load config", select config_8 or config_16 file. Now, we have a new list.

Here, we have to adress all lines one by one. Click on path of the line, paste the actual path of the file.

Or you can move "image" folder to the same folder with AndroidTool.exe.

And, finally clik "run" button.

If everything goes well, you can remove the som from pc and insert it to the head unit. Enjoy your Android 8.0 HU.

If you get an error after click "run" button, for example "match device type failed stop running" wait for suggestions from other friends, like I do :)

---------- Post added at 03:11 PM ---------- Previous post was at 03:04 PM ----------

By the way according to first attached recovery screen, you have Android 8.0 recovery. So you can not update system with update.img. On 8.0 recovery you have to use update.zip file for update the system.

If you can still get to the recovery just use "update.zip" file from sd card. (If you don't have sd card, ignore this message.)
[MTCD Hardware Development] Flying_Hero:
I've no idea, I haven't seen my unit as working.

But you can try a full wipe and clean install from recovery using update.zip, if you have an sd card slot.

By the way, what about recovery? Are the usb ports working in the recovery?
[MTCD Hardware Development] sand0rz:
It seems the usb ports don't work after flashing recovery (both recovery and rom) i tried every possible option

for now i am stuck at this horrible gold looking oreo rom

when i am back at home going to reflash back to 6 and check if it still work again on that recovery as it did before
[MTCD Hardware Development] sand0rz:
Tried all options now

"the device mismatch error" you can try this version of android tool instead

http://www.haoyuelectronics.com/service/RK3066/tools/windows/

It did work for me

As for not recognizing usb in both android and recovery

Flashed all files back to 6.0 and usb is working again in recovery and android.

[MENTION=4974080]marchnz[/MENTION] any idea if it's possible upgrading to oreo will loose usb functionality?

Do the PX3 Sofia's need anything special to use this method ? It is connected to pc thru the USB but as unknown device. And how do I actually short it to which pads ? I cant find a actual pic of a px3 only px5 and mine doesnt have the same pads. I can get to recovery and flash both update and mcu, but android wont actually boot all I get is the multimedia car audio screen then it either just reboots or it goes to a blank screen filled with garbled lines gets stuck for a few minutes & starts all over again..
[MTCD Hardware Development] MrWhiteBalcknBlue:
Guys, I am sorry if this may have been repeated already but I have tried to read through as many pages as possible and haven't got the answer I need. I have a PX3 board that failed to install Hal9k, there is no physical buttons no reset buttons, nothing, so I have resorted to searching the XDA forums to find a solution when I came to this thread. I have read the instructions and mostly understand that part but my PX3 Board doesn't look like ones I have seen on here so far. It's blue and labelled HCT-PX3-REV8.1, can I insert the jumper pins and resistors to the same ports on my board? I have no idea what android version I can or should install or where to look for it. I just want to get the stereo back in working order as the journeys in the car is starting to get very boring. If there is anything else I need to add for someone to help/guide me please let me know

OTG SOM pins are the same. Getting Maskrom if you need it differs - if MASKROM is needed, you'll need to figure out which pins to short.

[MTCD Hardware Development] Gordona80:
Hello to all. Seems that this method isn't working for me (my brother's unit). Although i have HCT-PX5-REV12 board, i think i tried everything suggested but always return to same result: "Unknown USB Device (Device descriptor request failed)".

This message appears only in muskrom mode.

What i did:

The cables has been soldered at board not to break the connector and eliminate loose connections.

I am powering the unit by external PSU (PC PSU) 5V, 3.3V and ground. Of course common ground with usb.

I already checked pins 35-36 (76 pin header) goes to USB controller.

I can only get a "ding" sound on windows in muskrom mode.

I tried reverse the D+, D- usb but then no hardware detected by windows.

Also different USB ports, without usb cable extender.

I didn't try different pc. I did...

Any ideas or help?

Thank you all.

hello all, after working 3 nights on my SOM I´m only left asking for help, as many here I tried to upgrade into A10 and now I have a non working device, I would even be happy with the stock rom now :LOL:.

- PX5 Rev 10 76Pins, Manufacture is MX

- soldered JIG, the device shows up in windows as Rockusbdevice

- Driver assistant 5.1 installed

- using RKDevtool 2.71 it always shows up as MASKROm device, I dont need tweezer trick, even while only using Pins 1 +5v Pin 5 Ground and Data -/+ on 29/30, without 3.3v on Pin 20/28

- It is possible to erase flash, at any setup with or without 3.3v connected

- I cannot flash anything, it always ends with "IDB Fail" with or without 3.3v connected, trying to write single partitions results in "Test failed"

- I have stable 3.3v , I even tried connecting Pin 9/15 also as stated in #1, but nothing changes

- using different Versions of RKDev results in same error or it does abort even earlier with "test failed"

- using Rockchip factory tool1.8 delivers same results, Version 5.3 looks totally different and I don´t know how to use this version

I tried several images and just the bootloader or recovery images from the basic OTA´s but itts always the same.

The fight is not over, since the SOM responds my hopes are still up that this brick can be revived.

Maybe some of the experienced people have a few hints for me. I´m located in Germany , so maybe someone nearby is even willing to try to fix this brick?

regards Joe
[MTCD Hardware Development] Kottex123:
