[Android Head-Units] MarkoDiMarko:
ROOTING THE YUEHOO YH-605

DISCLAIMER!!!!!

A. Dealing with firmware modifications and "upgrades", always involves a certain amount of risk bricking your device! DON'T attempt anything if you don't fully understand this and you are not prepared to end up with a "dead" device.

I'm not responsible for anything you try, don't come whining afterwards to me if anything bad happens, you accept full responsibility for your acts.

B. Having said that, I consider this procedure pretty safe. We'll be using the "update procedure" to install new firmware from an SD card. If something goes wrong, you can try to install the original unmodded firmware and go back to a working device.

C. This procedure was executed by me to my own YH-605b, with the following characteristics:

Hardware Information: 8-Core AllWinner - ROM 32GB - DDR3 4GB - 1024x600 - d2

Kernel Version: Linux 4.4.89 - Wed Aug 28 16:11:04 CST 2019

OS Version: KC1D01I1-O49-3.0.4.3.5-IVT-20190828

MCU Version: STM32-20190828-11-KC2-30

If anything is different in yours, please consider if you want to try this, even more :)

D. I received my unit 5 days ago. I haven't installed it to my car yet. It is sitting on my desk with just power applied to it. This means that no sound, steering wheel controls, or any other car related stuff have been tested. I'm just testing it as an Android device and everything seems to work fine. This also means that the next one who tries the procedure, has to test everything afterwards inside the car and kindly return feedback! I'm not planning in installing this unit in my car any time soon, to tell you the truth I get more pleasure in "playing" with it on my desk, than having it entertaining me in my car :) Unfortunately, we are living in strange times and right now it helps me kill my time and learn stuff.

E. After the "upgrade", everything will be factory reset. Self-explanatory, just have this in mind, any changes you had made or apps installed will be gone.

F. As far as I can understand, iGO is installed by hand on the device, after manufacturing, during final testing. This means that after the "upgrade", the application will not be there. If you want to keep it, just copy the iGO folder to an SD before the procedure and copy it back and reinstall the application afterwards. As far as I can see, everything else will be there. If something is missing, please report back so everybody will know.

By the way, if anyone could send me the iGO folder, would be nice :)

G. From my research, people kept telling that the way to do an upgrade is by using the "hidden" internal SD card slot. That's what I used, but by mistake at some point I realized that the external works too! So, you should be able to use the SD card slot on the front face left for the procedure, if this does not work, then be prepared to dismantle the device and use the internal one. Warranty void alert!

PROCEDURE!!!!!

Funny enough, the procedure will be a LOT shorter that the disclaimer! I'll try to keep things as simple as they can be...

1. You will need a microSD card, at least 4GB. Maybe it can work with a USB flash drive, but I didn't have the time to test it.

2. Download the zip file, using the following link.

https://mega.nz/#!YRZl1ADC!JGyl9Occ6CMmxxftkUDOyFxXSn2Fh8kTVI7XLn6qrPY

The file contains the already rooted image of the original firmware, done by me. Also, the PhoenixCard folder which is needed to prepare the SD card, a short video of how to use PhoenixCard (not done by me), and the Magisk Manager application for the device.

3. Extract everything, best to your root directory, e.g. C:\ .

4. Watch the short video. Execute the PhoenixCard application and "burn" the image to the SD card. Give it time, it will seem that it froze but eventually it will finish. Safely unplug the SD card from the computer.

5. Insert the SD card on the device and boot it up. There should be a progress bar if everything is going OK. Wait for it to finish, there should be a brief message like, "CARD OK". The screen then will start to change colors from gray to black and flickering. Don't worry, give it a minute or two and then remove power.

6. Remove the SD card and power it up. If everything went well, it should boot up to factory restored Android. Connect to wifi and enter your Google Play credentials, as usual.

7. Copy from the computer to your SD card, the Magisk Manager apk. Insert the SD card to the device and using ES File Explorer install the application, following the suggested steps.

8. Open Magisk Manager and follow the suggested step. The application should do its magic, reboot and you are done! You've finally got a rooted device :)

For anyone that tries this, please give feedback, it's essential in order to help others. If anything goes wrong, don't panic and explain what happened, I'll try to help.

If something goes very wrong, try to burn the SD card with the original image provided and "upgrade" it with this.

If someone is interested in the procedure of patching the original firmware, please tell me and I will prepare a short tutorial.

Have fun :)
