The link at xyauto has been changed. i need to download ui for 1280 x 720. Please update the link or alternative link
I didn't archive any 1280x720 UIs. My YT5760B is 1024x600 so thats the only one I archived in case need to go back to older version. Didn't anticipate xyauto to remove these UI files.
after updating the wrong UI with the wrong resolution (1920 x 720) now my screen is not working (black screen) while the functions are still working. i tried flashing the xyauto rom again but the screen doesn't come on either. i think need to re-flash UI 1280 x 720
Yes, wrong UI resolution make screen black as reported by other members. I document it here

Replacing Default Launcher WARNING xyauto seems to have removed UI17 and UI20 from their file servers (3/5/2023) Probably because they were bricking too many units in the field. Read more below. Note xyauto launchers is resolution specific so be sure to research and locate the right one. Wrong will
Maybe you can contact @boolaga in above link on how to reccover 1280 x 720 black screen from wrong resolution UI firmware install. Here are xyauto UI files that says compatible to 1280 x 720

Refer to my previous posts on around page 55 if you want any more info. I doubt I'll be able to provide any more than that. Good luck!
After updating to 1.73.7 my Zlink is crap.
Constantly cuts out, lags, etc.
It came with 3.9.27 version of ZLINK.
I read that zlink 5.3.8 apk version exists, does it work with the 1024x600 versions?
Can anyone share the apk and maybe the older 1.72 or 1.71 versions?

Can try the latest 3.9.48 and see if works better. zlink 5 unfortunately seems to have been removed. It seemed like pretty significant upgrade. Maybe still hiding somewhere on xyauto file server.

WiFi WiFi is faster with Bt turned off (confirmed on my unit) Someone on 4pda also reports faster wifi with longer antenna GU on MTK AC8257 cpu, Android 10, MCU: HDBEC - 4PDA Cellular HU includes 2 cellular SIM card slots. One internal (SIM1 require disassembly to get to it) and one via external
Maybe PM @hyz_123 to see if he has zlink 5 archive.

Hi karlisakis
For some reason, I found the 3.9.27 is best zlink to work with 5760B.
I believe 3.9.27 was also used on 1.73 maybe 1.72 as well.
You can try 3.9.48, but I have tried several releases newer than 3.9.27, they all have sound distortion issue, at least it happened with my 5760B.
I think do have zlink 5 saved on my computer somewhere, i will try to find it for you.
the only issue is Zlink 5 cannot be full screen, there is always an android task bar on top. if you dont mind this, than zlink5 should be good for you.

here is the zlink 5 ota file, it contains older version of zlink5.
I also have the zlink 5.3.17 apk. (I believe this is the newer version)
The ota file contains some system supporting files for running zlink5. (So just install zlink5 apk will not work)
the easiest way is to update with zlink5 ota file, and than install 5.3.17 apk to update zlink5 to latest version.
Reminder to restart the system before use.
Very cool thx, I'll put a link to these repositories on the website.
Installed 5.3.17 over my 5.3.8, install removed my launch icon from UI20 home page. Reboot HU, put zlink launch icon back and zlink runs CarPlay fine but not a user so no heavy testing.
I also found 5.3.8 (attached below)
BTW, there are 2 other online zlink repositories but I've not tried either of these
- 5.2.72 on apkcombo ZLINK APK (Android App) - Free Download (apkcombo.com). Installed fine but UI20 launch icon disappeared like 5.3.17 above post installed. Didn't reboot or test any further. I would guess it works fine if someone wants to try it. Installed 5.3.8 again and ran without any problem. Repository also have older 5.2.x versions.
- Zplus V1.1.12 on zjinnova website. No idea if this will work zlink activation key on these HUs. Its the 12MB file, use google translate to see the file name ( zLink mobile phone software - android ) 北京至简科技有限公司 - 至简科技 (zjinnova.com) For testing, installed it on my android phone, booted and got the version # but went no further than this.

Thanks a ton you all!
I will test and report back.
Problem arose after updating to 1.73.7
I just checked and the old install used to have the same zlink version, and then 3.8.34 before that.
So actually the issue came from the OS update.
Basically it drops zlink connection often, or worse, lags/freezes the stream (audio)

thanks for your support. I tried flashing your UI but the device still won't turn on. Can you upload your ROM for me?

Segue o vídeo meu amigo.
I have a picture of the screen with the colors misconfigured.
Touch is inverted.

There is a setting in Android settings called "invert colors" or similar. Try to use the search function on top of settings to find it....
Update on the ZLink issue.
Updating to ZLink 5 did not solve the issue.
I assume I need to reflash the OS.
I tried to load an older version, but it does not allow me to downgrade via usb flash drive.
My biggest issues now are the constant connection drop when using ZLink (it plays music via bluetooth just fine)
And the high pitch static/cpu/something sound via speakers - this one is hella annoying when there is no music, and I have not been able to find the culprit.
The static is there only when the unit tries to play music or any sound, when the amp turns off, no static.
It's clearly a cpu related, as it gets more active when the unit is trying to open an app, or play a video, its less pronounced when just idling.

Hello!
Anyone knows if it is possible to completely turn off the head unit? Not only to just turn off the screen, i want to power off the machine as in a PC or a smartphone.
Thanks in advance!

I've tried reversing it and it didn't work. Is it something to do with the video driver or screen recognition?

I am the author of the firmware released by the China Forum post you mentioned. First of all, correct you: I am not a QQ interest group. I am an Android Framework developer. The firmware I developed for this second time (YT5760B) can be written from 1.73.7 and any version below via USB flash disk without changing the partition table. This firmware supports English and automatic recognition of the vertical display screen, but I'm sorry that I made it based on the Chinese version, So it doesn't include Google services

I think not possible but people are still searching for solutions including Chinese qq interest group in post #1422. Not sure what solution they found, I asked in post #1423.

Use the partition table of 1.73.7 to update the unsupported USB flash disk to the officially released 1.73.8谢谢你分享你的作品。很有意思。我会把你修改后的ota命名为1.73.81.73.8厘米ota(中国修改了1.73.8 ota)在以下问题中
- 我理解< = 1 . 73 . 7 OTA可以装1.73.8cm ota吗？我猜1.73.8cm ota用1.73.7分区表？
- 如果1.73.8cm ota使用1.73.7分区表，那么1.73.8cm ota无法安装xyauto的1.73.8 ota。正确吗？
- 你知道xyauto 1.73.8和2/23/23 xyauto 1.73.7(国外版)有什么区别吗(分区表除外)？

您可以添加菜单来更改DSP版本。这是有帮助的，因为DSP应用程序似乎经常有问题
The 1.73.8 version has modified the DSP underlying driver, and the audio quality has been partially improved (but I think the 1.68 version is better)
No other bugs have been fixed1
Thank you. I understand your explanation.
I also installed 1.73.8 ota using TWRP (of course more difficult process than your modified 1.73.8 ota) Result also use 1.73.7 partition table. I guess result is exactly same as non Chinese 2/23/23 1.73.7 ota? So I suggest to xda members to just use 2/23/23 1.73.7 ota.
Do you know why 1.73.8 with new partition table is faster (everyone (including me) tested by PC flashing firmware say faster) than 1.73.7 partition table? I guess maybe eMMC access improvement by block alignment? (My guess summary in post #1423)1
This is just an illusion. Xyauto only reduces the length of the logo partition, so the starting position of all the partitions has changed. The speed of writing has nothing to do with it. It is limited by the performance of PC and USB speed -
4i did it !!! i did it !!! my radio works!! to much people with this problem and i found the solution trying bored files from xygala, i was bored, i downloaded all the files in that drive 1 by 1.. seems it’s a driver for lg screens, i will edit this to make a tutorial, but i need help to do it, my english is not so good3Late Feb release of an xyauto UI is pretty good. Has maps (I use with google maps app with offline maps), radio, HU music player, a fixed app launch icon pane (left vertical) and a user changeable app launch icon pane (lower bottom) all on one screen.
Generally quite nice. google maps has voice input search, auto dark mode at night while navigating (none navigation mode unfortunately stays in day mode) map will be always north up while driving without navigation route.
patch file link Note this seems to be for 1024x600 screen only. Didn't see it in other resolution folders.
Mode switching is a bit mysterious (I have a steering wheel button programmed to switch modes). In the old default UI, mode switch with switch between currently running apps. Seems to do nothing on this UI while being displayed.
This launcher provide everything I use so no need to fiddle with the HU much. Just power on the car and drive. The useful features are
- FM radio (wife listens to this and its her car)
- Maps always displayed and track your position smoothly (Seen other launchers with map. Position only update every second or so, very jerky display). Google maps fixed to north up unless navigating. Voice input destination via mic icon on google maps search bar. Maps always in bright color mode (quite bright at night but area is not entire screen) Navigation will auto change to dark mode at night.
- BT works if setup to auto pair. Incoming calls pops up on screen. Can voice command out going calls with iPhone easily. Just say "siri call xxx" with iPhone mic able to hear you. iPhone looks up your contact and dials while connecting to HU's BT for speaker/mic sound.
- Music player will play all music files in the system/USB stick.
- Color choices are nice. Colorful but background is dim for night time use. Only issue is google maps none navigation mode display stays bright. Other nav software might handle this better.
- Google maps generally likes portrait displays like a phone. This horizontal smaller window sometimes hide the next driving intersection change behind the green direction box on top. Not too big of a problem.
- Left column icons are not changeable. Bottom row is user changeable.3I have recorder a video with the YT5760B system upgrade. It takes about 5 minutes to complete. In the attached ZIP file you can find the video.3The XYgala.com has released another newer 1.73.7 split screen firmware (release date 28 October).
And UI20 add-on pack has also been updated, it made adding the app to main screen bit easier.
The new firmware updated the Zlink to ver 3.9.43, which causes sound/music distortion when using Carpaly.
At least this problem appeared on my HU.
if you are having the same problem, you can install zlink ver 3.9.27 from my previous post.3
Just installed 1.73.6 on 5760B 1024*600, didn't wipe user data.
Actually, I forgot and left 1.73.3 (don't recall if it was 5/24 or 7/25 version) on the USB stick w/1.73.6 and 1.73.3 got installed which wiped my user data. But then I installed 1.73.6 over this without wiping user data.
Biggest change I notice is just the 2x boot up pop sound is gone. So maybe xyauto have more orderly sound hardware initialization now
