Brand new UIS8762 qled 6gb 128gb 8core never started, and no support from Witson

[Peter studio tech]

Hi,
I've been googling and searching here and on Youtube for three weeks and I can't find any help.
My brand new head unit doesn't start, and has never started. The touch buttons don't work so after hours and days seaching the web I found out that I could at least get it to the boot logo by pushing a pin into the reset hole for 10 seconds, another short push and then a third push for 5 seconds, but that's about it.
Sometimes when I do that I get to a "no command" screen and then nothing.

When I contacted Witson who sold it to me, they sent me a file to install, but the problem is that the update stops (around 80-90%) and reboots before it's finished. After 3 restarts/reboots of the update it just goes black again. After sending several photos and videos to Witson of what's going on I asked for a refund and then they just stopped answering me. Nice, huh. (And I've followed their instructions to push the reset button when the boot logo appears - let it reboot - push the reset button when the boot logo appears - let it reboot - push the reset button when the boot logo appears.

So now I'm stuck here with a head unit that's never been used. Could there be a chance that they sent me the wrong update perhaps? I'm not used to head units but I've tried many things to solve it. I can't get into recovery mode, god knows I've tried for days with maaaany different tricks picked up on the web. I've even opened it up and tried to reset by short circuiting the special poles people say you should do. Nothing helps. I've tried to figure out what other brand sells these to find another file to install, and so far I've tried at least 10 different files, both USB contacts and three different USB FAT32 sticks, but no difference. Boot loop is the only thing this head unit is capable of.
If anyony could kindly assist me it would be extremely appreciated.
I'll try to post some pictures for you. I don't even know the proper name of this thing.
It's supposed to be a Witson DHG (W2-DHX1001) with Android 12, , but it seems to have many names. As I said, it's never started up properly and I've never played with a device like this before.
Many thanks!

This looks like a UIS 7862 FYT unit. DO the files they sent include a lsec6315update and a 6315_1.zip?
Normally, when the update fails you will get a message in red about the failure and the unit will reboot after 5 minutes or so, yours just reboots?
Anyway, if you got the unit from Aliexpress the safest thing would be to open a dispute with them.

Hi,
Thanks for your reply.

Thanks, I'm not by the computer right now but they sent me a 2,1gb zip-file with a zipped 6315 file name in it. (Does that make sense? ) Not sure if both those files was in that package, but one of them was.
I can't recall the exact name right now. But they just wrote that I should unzip the big file as is onto a USB stick and do as described earlier.

There was no red alert text when I used the file. Only reboot after reboot at around midnight 80% install. (One of the other files I downloaded later from the web showed that red failure text)

I did open a dispute and was reimbursed $160 of the $400 I spent in total. So here I am $240 down and a piece of glass.

Would be fantastic if someone has a file that fits this head unit or someone knows if there's a possibility that the main board or something else is broken.

Cheers

You definitely have a FYT unit.
There is plenty of info on this unit in this thread.

Thanks, I'll check it out. Much appreciated.

Ah, yes I recognize that thread. Been reading a lot in it but I couldn't make anything out of it in relation to my unit. I guess I have to give it another go and see if I can make anything out of it now when I know it's a FYT unit, thanks.

Short version:
Get a FAT32-formatted USB stick, good quality. Bad USBs may cause setup to abort.
Copy the firmware files (minimum: config.txt, 6315_1.zip, lsec6315update and updatecfg.txt) to the stick.
updatecfg.txt should contain

test
twipe_all

config.txt should look like

#test
#ro.fyt.launcher = com.android.launcher04
sys.fyt.bluetooth_type=1
persist.fyt.zh_frontview_enable=false
sys.fyt.ec_version=6
ro.fyt.splitscreen=0
persist.syu.camera360 = 1
# 0不带360 1带360
persist.lsec.pip_rect_clear=true
ro.sf.swrotation=90
persist.lsec.enable_a2dp=true
ro.lsec.btname=Bluetooth 2
persist.lsec.iphone_usb=true
carmark#0
persist.sys.navi.carmarkset=0

launcher name may be different, depends on firmware version.

Make sure 6315_1.zip and lsec6315 update are both dated either before or after July 2, 2022. You cannot mix on from before with another one from after.

You can get a suitable firmware from here. Look for the 7862/9" 10" line ( or 7862-9"-10"-360: if you have 360 view)
Insert the USB and start the unit. You may have to reset up to 5 times until it boots from the USB stick.
If you get an error message, post it here.
If you don't and it still aborts at 80% chances are you have a HW failure

 

[Peter studio tech]

Amazing, thank you for the detailed explanation. Well needed for a noob in this area.

I'll try it out when I get back on the computer later tonight. I guess the night sleep is canceled.

Thanks again, very impressive.
I'll get back to you as soon as I have any results.

I think that this file update he got is not for his device, it does not recognize hardware and stops in a middle of process of install.
Install other updates suitable for your model and year and see if error repeats again.

Hi Anton,
Thanks. It's what I suspected too. But it seems all the different files I've tried has behaved the same way so far. I'm trying this file that was recommended by @m00n61 here above. So far to reboots and same thing. Stops and reboots at the exact same spot. Switching USB and USB stick in a few minutes for continued trying.

Yes, unfortunately it looks like it's the same thing with the recommended files (7862/9). It reboots at the same point at the install and no error messages. I'm trying out the other USB input now and will then try yet another USB stick.
Thanks again.

 

[Peter studio tech]

So I tried to install both the whole file and only the necessary files @m00n61 mentioned earlier. And I tried this on both of the USB inputs and with three different USB sticks. All with the same outcome. the install stops exactly where I showed in the picture in the first post, and then reboots, restarts the install and it goes on like this three times until it just goes black.

Is there any other way that may help? I've read about connecting the head unit to a computer with a USBa-USBa cable and some sort of sofware.

Thanks for your input!

Yes, including flashing of ROM but it must be done with guidance and by a pro...
But it is last resort, let's try something else first.
Format SD card (if device has slot for it) in FAT 32 not exFAT with default allocation settings - not USB drive but SD card !

- if device has no SD card slot use any SD card reader if you have any and insert it then into USB slot with update files on it
- before unit boot try tapping with one finger on the middle of screen till see message DETECTED
- let the update begin
- if same error appears - press RESET button rapidly each time units starts for 5 times
- as soon as unit starts again tap the screen with all five fingers till recovery mode begins (message erasing will apear and begin to erase system files)
- when boots again into Android download a application named FILE MANAGER from Google Playstore
- go to app
- on the left side of app there is a menu - choose ROOT folder it looks like this "/.."
- there are system files that are hidden from users
- if unit is rooted you can go inside each of this folder
- if not rooted, delete the CACHE folder
- restart unit and try update again with SD card or USB drive

Fingers crossed !

Thank you so much! I'll try it out tonight! (it's morning here)

The unit has no card slot so I'll give it a go with a card reader.

I've read about the five finger tap (which didn't work on this one) but never the one finger tap. Looking forward to try out your suggestions!

Thanks!

Five tap is not working on every device, every device has different way.
You must find your way to get into recovery mode and get system to clear cache and junk files
Also, maybe you have residual update files left on main folders like factorysettings.bin log files mem.ini etc. delete those too !

BTW you can go into recovery mode if you can access Android and go from infotainment menu or from factory settings (accessed with PIN code)

 

[Peter studio tech]

Yes thank you, I've yet to figure out how to get into recovery mode. And I've never been able to start the device, so recovery mode seems like prio one so far, if I can't get any of the files to work via SD card etc.

Thanks!
