Trouble with "error 21" while trying to update.

Hi guys, I have an Xtron TE706PL Android 8 headunit in my boat (I'm not rich, it's a crap boat! lol) which is a PX5 MTCE GS V2.88_3 machine and most of the time It refuses to boot. I am in thi thread because i wanted to try this version of the software but if I should be somewhere else please point me in the right direction.

It will display the first "navigation" screen and occasionally carry on to the "android" logo and boot, but mostly the nav logo only displays for a couple off second then the screen goes blank and that's it. If I put an SD card in the slot the unit will always boot but only into the recovery screen that allow you to do updates etc so I suspect a software problem rather than hardware, on the rare occasion I can get it to start up properly it runs fine and leaving it disconnected from all power for even several days makes no difference.

I have the latest firmware supplied to me by Xtron and I have tried the download at the start of this thread but when I try to update from either SD card or USB stick I get "Signature verification failed, Error 21"

I have searched the tread and seen this mentioned a couple of times but can't find any answers, my unit is out of warranty and I would like it rooted anyway so i hope someone has some idea how I can get an install going!

I have another, identical unit in my car which is on V2.94_3 and that one has been working perfectly.

I don't know much about these device but i have a reasonable ability to follow instructions and have built PC and have managed to root most of my phones OK so if someone more knowledgeable can come up with an idea I'm all ears..

Thanks for any help. :)

You made everything wrong...

Malaysk and Hal has their own Recovery.

If you want to install Malaysk rom you need his recovery.

With Hal9k rom it is the same.

And you need a working recovery for every version. 6, 8 and 9. You can not use a version 6 recovery for a version 8 Android.

You first have to install the right recovery.

I would start from the beginning.

Install the stock rom that came with your head unit and from there install the rom you want with the working and right recovery.
[MTCD Software Development] cleverdicky:
I'd also check and make sure you have a good +12-13.5v power supply
[MTCD Software Development] SomebodySysop:
Perfectly logical. I just have one question: How do I install the stock rom that came with head unit (which they have sent me) if I cannot get into recovery?

Right now, when I create a bootable SD, it has Recover v6.x on it. Since the unit crashed while running Malaysk version 8 rom, how do I create a bootable disk with Recovery v8.x on it?
[MTCD Software Development] Popuptoaster:
In answer to my own question, in case it helps anyone else, I could not et past the error from the recovery screen, however, having the image on a USB stick plugged into the machine on a rare occasion when it finally decided to boot properly meant it picked up the update and asked if I wanted to instal it, from there everything worked as it should and the machine now seems to be working OK on it original firmware.

I may give it a while before I make another attempt on installing the one on this thread!

You must use MTC dialer! Find the appropriate thread on the forum. However try to speak in English otherwise it is very difficult to answer you

Devi utilizzare MTC dialer! Trovi l'apposito thread sul forum. Comunque cerca di parlare in inglese altrimenti è molto difficile ti rispondano

When will the hal9k 9 rom be released?
[MTCD Software Development] verszipo:
When it will be ready ;)

Usually it's not a nice thing to ask for ETAs on ROMs because you have to remember, the guy/guys making the rom are doing it in their spare time, they are not hired/payed for it, so they allocate whatever time they can spare.

If you don't want to wait, you can always start researching what's needed to make a ROM and make your own ;)

Hi Guys..

Thank you all for the hard work... now i have a question i own a Eonon GA8150A T8 Octa-Core A7 1.8GHz ( 2gb - 32gb ) version with an alwinner cpu...

Now the question.. can this rom also be used for this unit.. As i have understand that there is also a same unit but slightly different from mine..

Thank you in advance....

Just did this on my xtrons PE9890BIPL using a USB hard drive with a 2GB partition formatted to Fat32 and used a USB keyboard. Heart was pounding praying for no problems as I only got it brand new yesterday but went through flawless! Thanks for the exploit and amazing ROM Hay9k

Quick question, I had an OTA update available at just over 70MB, can we apply these OTA updates?
[MTCD Software Development] nic2k:
Look at the title of the thread [ROM][PX5][Oreo][8.0.0] Hal9k ROM 3 for MTCD/E head units with Android 8/6, [PX5] refers to the SoC. Your SoC is T8.

Noooo I applied both OTA updates and Viper4android updated to the really nice material design but "lock effect mode" has been removed! That was how you you could apply Viper Bass, Viper Clarity and more to the speaker now its back to a tinny system lol.

Any ideas or how to get the old version back?

---------- Post added at 07:49 PM ---------- Previous post was at 07:00 PM ----------

Got my bass back!

A few others responded not knowing how to do this and I was a little confused myself but the way I did it is..

Install Root Explorer from play store

Go to Magisk > Menu (top left) > modules > click the bin icon next to Viper4Android and a message will appear saying it will be deleted at reboot

Open root explorer and grant root permission, in root explorer at the top you will have "/" and "storage" chose "/" which is the root directory and navigate to

"/oem/bundled_uninstall_back-app/ViPER4Android/ViPER4Android.apk" hold down on the Viper4android apk and delete it

Restart head unit and Viper4android will be gone.

Now download the attached Viper4android zip file and again open root explorer and this time be in "storage" and click into "downloads" hold down on the Viper4android zip and extract here.. The Viper4android apk will get extracted and then click on that and install as normal, open Viper4android and install the recommended driver and reboot.

Done.

One thing I was confused with is with Viper4android being a ZIP I thought it would be a Magisk module installable zip or a zip that's installed in recovery

Thank you Nic2k... i figured.. is there anyone who know's if there is a custom rom for my model HU..?

[MTCD Software Development] nic2k:
AFAIK there's no custom ROM for allwinner T8 best you can hope for is to ROOT it and replace the launcher.

Any idea how to get an xbox one controller to work? USB Keyboard, mouse and hard drive work great but the controller doesn't get detected at all via USB and it also can't pair via Bluetooth either?
[MTCD Software Development] nic2k:
Your HU is neither a PX5 and MTCD/E so no.
[MTCD Software Development] mrsweet1991:
Did you have any luck with this? I'm thinking of giving the comfast adapter a go. I don't have the MD725 Bluetooth on my unit I don't think (in factory settings it states something else) so I'm wondering if I get this adapter and change my Bluetooth factory setting to Md725 it might load the drivers properly without any conflicts? WiFi is crap on the factory installed board but more importantly I'd like Bluetooth to connect to a controller (xbox one) as well.
[MTCD Software Development] GoNzCiD:
After try al software configurations I has read, I didn't have luck.

The comfast USB module didn't work for me.

The only solution for me is replace the BT/wifi module.
[MTCD Software Development] mrsweet1991:
That's a shame, it's so hard to get working by the looks of it. As for the comfast adapter, are you based in the UK? I was thinking of buying it off you to try on mine?

Hi All,

I figured out a way to get an xbox controller to work on my head unit. Usually, when plugged in it does nothing and apps like USB Host Controller would show that its detected but the unit doesnt seem to know what to do with it. Changing USB debug options did nothing either.

So anyway, there's a Play Store app called "USB/BT Joystick Center 2019" and that identified the controller but then allows you to emulate it as an xbox controller. I used the settings:

IME turned on

JOY set to 360

J > T turned on

Then you press "search normal" and the controller will show in the app and the controller will vibrate. If you click on the controller icon and then map every button including analogue sticks you just then tab out of the app and launch anything with controller support.
[MTCD Software Development] GoNzCiD:

Hi,

On my smartphone, there is a native blue light filter which commute automatically with the sunset and sunrise. I really love it, and I would like to have the same on my android head unit!

They are some applications like twilight on the play store which can do the same, but the color is not perfect because it is an overlay, and it is not working on the navigation bar...

F.lux is a similar application which work on rooted devices, and it is really better than the overlay solution.

However, this application doesn't work for Rockchip device...

Do you know an application like this which work on px5 devices as root? Or maybe you can implement this natively on this amazing Hal9k ROM? :)

Anyone have any ideas how to get the trajectory lines to move with the steering wheel on an XTRONS PE9890BIPL it integrates with the CANBUS but I can't seem to find the option for dynamic trajectory lines, I've tried extra settings and also factory settings (pin code 126) and wasn't sure if maybe its the reverse app or another setting perhaps?

I've noticed that the ruler guide doesn't move, but the road display does. Is there a way to make the ruler guides move with it as well?
[MTCD Software Development] marchnz:
I can confirm working OBDLink LX w/HAL9k v3.1.2. Also generic 'knock off' adapter pairs quickly, without fuss.

Note: For OBDLink-LX (and possibly other genuine OBD BT adapters) the Android PIN must be 0000 (was previously 1234) - OBDLink changed from 1234 to 0000 as of OBDLink firmware 4.5.2. If your OBD adapter has a legacy pin the headunit must be set to the same four digit PIN.

TLDR for Genuine OBDLink-LX the headunit BT PIN must be set to 0000 to enable pairing. HAL9k has configured this ROM default as 1234 (which OBDLink legacy PIN once was....)

[MTCD Software Development] mrsweet1991:
Yeah it's a 3 series BMW and the XTRONS comes with a Cambus decoder which I assume is how the road display moves with the steering wheel but It's weird as I would have preferred the other way around where the ruler guide moves instead and yes I have a camera installed and factory fitted sensors

[MTCD Software Development] HatManSan:
Hal9k, just an inquiry. Are you planning on releasing 3.1.3 or a 3.2 etc or are you moving to 9.0 or of course 10, or are you know satisfied and moving on altogether. Mainly asking asking i will be getting a new Xtrons PQ1939BIPL or similar which ships with 9.0 currently. Not rushing as the resolution is poor. 1280x480 is a cheap shot by the manufacturer!! As headunit with a wider aspect ratio are becoming more common, it stands to reason that some developers will be looking into making use of the greater horizontal resolution rather than simply allowing the graphics to stretch. Do you think you will embrace the wider screens?

Thanks, that's what I try to do, but now I get: formatting user disk failed in the Rockchip SD tool.

Okay after a few tries it works fine. But when I insert the SD my HU does not boot. I'm getting really annoyed because I want to install other ROMs... What's going wrong? I followed a few different guides with the same result.
[MTCD Software Development] gigagames21:
Did your run the tool as Admin? If no, you need to.

If yes. Try to Format the SD-Card with the Windows tools, if it also fails, something Wrong with you SD card. Or directly try an other SD card

"when I insert the SD my HU does not boot."

What happens? Does it show an error, or is it just Black (you need to press the Power button / cut the Power and reconnect it to power)
[MTCD Software Development] Bose321:
It runs as admin when you open it. Doing so manually is the same.

It's installed now but my device does not boot at all. Can't I use a bootable USB? Nothing happens when I try.
[MTCD Software Development] gigagames21:
Maybe you SD card is damaged.

I cant realy help you, becouse i doint know what you do and what you doint do.

Tell us more.

(and man is this webpage slow -.-)
[MTCD Software Development] Bose321:
I just follow the steps of the first page on the Android 6 tutorial. The SD card works fine in my PC with other files and it writes the bootable SD just fine. What else is there to tell?

I should follow the Android 6 steps for when Android 9 is stock right?
[MTCD Software Development] gigagames21:
Yes you need to Follow the Android 6 steps, if you have Android 9.

1. How big is the SD card? (2/4/8 is recommended, it worked by me with a 16GB but biger SD card can make Trouble)

2. sdupdate.img replaced?

3. SD card safe removed from Windows? (If not, it can be that there is still DATA in the Buffer, that need to be written)

4. SD card insertet into GPS slot? (NOT VIA USB ADAPTER)?

5. What happens if you reboot the System? (It need to be Complete off, not just in "Sleep").

If it does absolut nothing (Just keeps being Black) what happens if you try to Start it Without SD card? Will it Boot into Android 9 or keeps Black?

EDIT:

You have px5 and MCU MTCD or MTCE?

Or did you ahve px6?
[MTCD Software Development] Bose321:
I've got a 2GB SD card that I format with the tool with a USB adapter on my PC. I use the bootcard.img and then replace the sdupdate.img as said. I indeed safe remove the SD from Windows 10. I then insert the SD card directly in the GPS slot in my HU.

If I reboot there's a black screen (either reboot via software or RESET button). When I remove the SD card and reboot again it boots to Android 9.

It's a PX5 with right now MTCD MCU I believe, but I'm not 100% sure. I could try to flash the MCU first if that helps anything. I have the option for it in my settings menu, but it says it can't find the file when I put it on my USB, or should it be on my SD? Or can I install it via USB via recovery by loading the file?
[MTCD Software Development] gigagames21:
With an MCU update i cant help you.

I would suggest, Format the SD card with Windows tools. Then flash it again.

Boot into Recovery, insert SD card, and Reboot from Revovery, if it still doesent work, i cant help you. Sry
[MTCD Software Development] Bose321:
So with reboot from recovery you mean just press RESET while I am in the recovery already? Believe I tried that, but still black screen then.
[MTCD Software Development] gigagames21:
No, i mean select "Reboot System Now" But first, Reflash the SD card
