Did you try "126" ?

use 123456 for extra settings. Still trying to figure out the rest. Please share if you find any other codes!

developer options
Developer options app allows you into them options, but now usb debugging requires a code also

Where do I get king root? Is that the same as kingoroot? So many of these sites look sketchy.

ThAnks, but there is no code for installing unknown apk's

If there is no option in settings, try downloading apk installer in play store. Also if you tap the build section under about device 7 times it will open developer options, may be the option in there

123456 and 7890 try these.

MCU Codes
These codes can be entered when accessing the Factory Settings menu item
• m123456 - opens Factory Settings in "super" mode -- makes another option visible; Launcher type (not sure what they mean though)
• adbon - seems to enable adb on the usb port. Might enable it for all usb ports (haven't tested it yet)
• *#hct#root# - enables persistent root adb on usb port(s) (might be an easy way to root roms, will have to do some testing)
• adboff - disables adb on usb port(s)
• keject - simulates the eject button for the DVD drive
• kpower - simulates the power button
• hcttouch - displays information about the touchscreen/calibration?
• hctbtup - some sort of bluetooth update mechanism?
• hctbtte0-9,0-9,0-9 - some sort of bluetooth testing code -- after the hctbtte there should be 3 digits, ranging from 0-9. Haven't looked into their meaning.
I hope this'd help

Android head unit - MTCD KD - Color inversion - impossible to revert

Hi dear all,
I just recieved a new android car 2din head unit, it's a MTCD version with the last firmware version 5.1.1 android+KD+04.05.2016 and I have an issue with the display.
I have an inverted colors on the display.
No way to return to real colors.
I have wiped all users settings in recovery mode.
I have tried via adb to set pm clean com.android.systemui with no success.
Can you please help me ?
Thanks
Artius

The only thing that comes to my mind is this :
Have you checked the "developer options"?. There is a option witch does invert colors. If it is not switched on you might just turn it on and see if solves your issue.

Thank you Marmalux.
I will try your solution this evening
Do you know how to activate "developer options" on this android 5.1.1 MTCD unit ?
Because when I use 126 password in the advanced option I dont have any item with developper options.
Thanks in advance
Artius

Developer options are android specific options, and is not the "factory setings" menu. In main setings menu at the end you should find the developer options.
Regarding the password for factory settings you can also try "m12345" or "m123456" or "587" (this one i'm not sure, but it is definitely begining eith 5, you can find it in the wiki of xda)

How to force 4G only (LTE only) Mode?

Can someone help me I am trying to force my Huawei P10 Plus to use LTE/4G only mode. I have latest Firmware/Patch Level.
I have tryed many service codes in format like *#*#.....#*#* codes but I can not set the LTE Only mode.
Isn't it possible without "root"?

It is possible to force "4G only" without root. First download "Setting Database Editor" from playstore. Open it and look for "hw_networkmode_preferences". I use this value "9,3,2,1,11" on my phone. Save it and restart your phone. If you still don't get "4G only" option then you need to open the "Setting Database Editor" again and look for "hw_add_4g_only". Mine was set to "250". You need to change it according to your country mobile code. Look for your mobile country code here: https://en.wikipedia.org/wiki/Mobile_country_code. In my case I change the value to "250;502" since 502 is my country code. Save it and restart your phone.
Tested on rebranded P10 Plus 256GB.

Thank you very much for your Help! I already installed the DB Settings Editor and found out that hw_networkmode_preferences were already "9,3,2,1,11" so this wasn't the case. Additionally I found that I have to add "hw_add_4g_only" so I added it with the wrong Country Code because I didn't know what the hw_add_4g_only means. I was searching for it a few days now and never got an answer, so I was trying to ask here. And you made it clear now. The Wikipedia Link was very helpful and it works now for my Country. I have to set it 262 for O2 Telefonic Germany.
So again Thank you very very much!

Using Huawei P10 (VTR-L29) 8.0.0.374 (185) solution above works for me too.

Worked on my Samsung Galaxy S9

Honor 6X is stubborn as heel... Nothing works.
Can't even find the commands... Sigh!

First Method :
1. Use SIM 1 as the default connection setting
2.
You need to install this app for FREE
at Google Play
https://play.google.com/store/apps/details?id=com.teknokia.force4glteonly
pro version : https://play.google.com/store/apps/details?id=com.teknokia.force4glteonlypro
galaxy store: https://apps.samsung.com/appquery/appDetail.as?appId=com.teknokia.force4glteonly
pro version : https://apps.samsung.com/appquery/appDetail.as?appId=com.teknokia.force4glteonlypro
3. Run the application, press the SIM 1 only or Android testing button. You will enter two LTE Switcher options and also 2 Android testing options.
4. You can try all of them which support your phone.
If the telecommunication operator you are using does not support VoLTE (Voice over LTE) and uses LTE Only Mode, so regular calls will be blocked.
Second Method :
1. DOWNLOAD Force 4G LTE Only 2020 Pro application from Google Play
2. Run the Application
3. Select SIM 1 Only menu, then Hidden Activity
4. wait to load until 100%
5. tap the search box type RadioInfo
6. In the DEvice Info app section, there is a RadioInfo activity.
7. Long Tap 3 options will appear: Create Shortcut, Launch Activity, Edit Shortcut. I recommend Select Create Shortcut to make it easier for us to enter network activity mode without having to bother opening the Force 4G LTE Only 2020 Pro application.
8. Please select Launch Activity to enter the Radio Info
9. Select LTE Only in set preferred network type

I was able to get it working on my huawei y7a sometime last year using settings database editor. Abouy 2 weeks ago i factory reset my device due to an unrelated issue and now when i try to enable it again i get an error saying my system software has rejected the edit. I tried with the version of setedit from f-droid and got the following "Unexpected failure you shouldn't not change private system settings." does anyone know what the problem could be?

I have the same issue with p30 pro. It seems to me that after some recent updates, they've locked those settings somehow.

I found a solution. You would have to use "Adb shell" (usb debugging).
The code is:
adb shell settings put system hw_networkmode_preference 11

I can't figure out the factory settings code. Please help

Hi there!
I really need to change some factory settings on my android HU. Anyone here who can help me?
Thanks!!
How can i post an image??

It would help to know which HU you have. 126 or 1260 are used by many HU but 8888 and 3368 is used by some brands too. Allwinner based HU have a more complicated code. Go to the general settings menu and hit the gear icon then type the code to get into factory settings.

[PX6] [STM32] [ROM] in need

Greetings!
Browsing the forum I have figured that currently(January 2020) no custom ROM is available for PX6 which came with STM32 MCU.
As probably many owner have noticed the stock ROM has many flaw and severe deficiency/complete lack of customization.
As far as I know, sadly no Hal9k ROM development is planned for STM32 model currently. :crying:
I think many head unit is already or being shipped with STM32 MCU and I have a feeling that many hobby hacker (who can only install a ROM) including myself would be grateful having a sophisticated ROM for this model too.
I would like to ask owners as well to use this thread and express if they are also in need for a custom ROM.
Thank you! :highfive:

I need rom
OS Version: KC1E0101-PA1-1.1.4.3.1-BLINK161-20191115-701F
MCU: STM32-20190918-11-KC6-37

Hello to all!
After some days owning one of our favorite HU I gathered some info I want to share with yall. :cyclops:
Due to some random system reboot during normal operation I have also conducted investigation on heat dissipation. Simply put, these HUs has bad heat dissipation from factory.
The system during an AnTuTu CPU stress test hit 80 C which is not healthy for the unit and it can cause thermal shutdown as thermal throttling is not sufficiently implemented.
I added a medium sized heat sink and that reduced peak temperature to around 50 C.
To make the system cool on hot summer days I added also a 30x30x10 fan. With fan the peak reduced to around 40 C.
After the modification my HU is running stable, I was not able to make it reboot so far no matter how hard I use it.
P.S.: If any1 has info on the 4-pin connector next to the big white connector please let me know!
Update: added images with cooling added.

Hi everyone!
This post is for those who wants to know their device as much as possible or has issue with bluetooth / display or just curious or wants to update OS in future.
There is a hidden "Factory Settings" to access it you need to press: "Kernel Version" > "OS Version" > "Kernel V." > "OS V." > "Kernel V." > "OS V.".
Some settings in there are very useful actually.
For those who has fluctuating grey color at certain brightness I recommend "Factory Settings" > "Other" > "Panel learning" > "Vcom regulate value".
For those who want to make colors of the display simply nicer I recommend "Factory Settings" > "Other" > "Display Color Adjust Settings".
:good:

thanx for the information. do you possibly have the mcu file for this device. I need to fix mine , I flashed a wrong mcu file and now the screen is twisted and mirrored. Thanx in advance

Hi Simbac,
before you flash any file, if your display is still responsive try "Factory Settings" > "Other" > "Touch learning" > "Step1: Screen learning".
If it does not help, you can find my config files:
One exported from main factory setting menu (android_config1579383003862..1) original file extension is ".1" but I was only able to upload to XDA as .img so please rename it if you want to use it
One from panel learning menu (BHDPanelConfig.img)
And one from touch learning menu (ts_config.xml)
After copy them to a FAT32 formatted USB drive you plug into your HU the updater app should launch automatically. My files are for "CONFIG" and "PNL" (panel) and "TS" (touch).
:good:

If your device does not get pass the bootloader so cannot get into the Android OS then you cannot use this method to update ROM. Did you enable ADB via TCP?

You can find my video at youtube.com/watch?v=sDxmmYL-nIg
It can boot to android, because I can saw that my phone can connect to the HU's bluetooth. I already checked the wifi but it seems that HU don't connect to access point.

have you tried to enter recovery following this procedure? (remove spaces) https: //drive.google.com /open?id= 16CfginUDta01NfMxt7B3a8g0CyniUnit

You can try an "Erase with reset button". Note that all of your data and apps will be lost if it completes erasing and android should be in factory state after this erase.
Check my video here: link
Timing of presses is not exactly known neither the number of presses. I was able to start erase with most success by pressing 1+4 times. You know if you did right if white screen appears for a short time (at least on my STM32 HU).
Good luck!

Let me ask something.
If you enter recovery menu by reset button you can also navigate and select options there with the same button.
If you enter recovery menu by typing to terminal: "reboot recovery" than can you use the button again for navigation and select?

I see from your screenshot that you have the LESS ugly version of the UI than my recent unit. The radio app on mine is especially difficult to use. I'm been looking for the radio apk from a unit like yours. I was able to extract mine (it was called com.hzbhd.radio.apk) using "APK Extractor" from the Play Store. If you would post your radio APK I'd love to see if it would run on mine. Thanks!

No, using "reboot recovery" you have to use an external usb keyboard to navigate and select and the selectable option is different (example ther's not USB option, only SD) , but I don't know why
