I try to update my unit, android, MCU but nothing work, so i hope u can help me, cause Erisin dont reply to my problem.

Hi
Did you checked if your wires are ok? Maybe the accident caused some connections to get loose.

I allready check but nothing seems to be broke.
I search for the card board détail for find wifi module but i didnt get them

Your USB chip died, just like mine did. Took away all that had something to do with usb, such as wifi, external disc option, 3g...

Nothing can be do for repair ?
The front usb work for u ?

None of the usb ports work because usb controller died on board.
First my wifi started to go off by itself, and soon enough nothing worked that could be connected to usb.
You should change the mainboard, or buy another device.
But first try factory reset.

In my case, front USB work (just the mini USB/USB cable move a lot, so i lost connection).
I allready try a factory reset and dont work too. For information, when i put WIFI dongle on USB Front, i can swap wifi ON too., but this dongle work on my computer.
Where i can find a mainboard ?

From your seller, I guess...

USB Sync not working

Greetings,
I have an HTC 3301, unlock, with Shady WM6.5 rom. I´ve had a problem with a replacement battery (bought from eBay) my older battery (it was heating) and changed to the original one.
After this issue, I could not use usb connectivity anymore.
Plugged with the USB cable, but Windows does not detect anything, but still charges the device.
Plugged the headset and it still working flawlessly.
I´m syncind using bluetooth, but lose the usb connectivity sucks.
I dunno what to do. Any ideas?
Thanks
Hi There
Firstly have you got the latest activesync?
You will need 4.5
If you already have this remove it from your PC download and reinstal a new one as I have had a few connection problems in the past and this does seem to solve the problem.
It might also be a good idea to do a hard reset on the phone if you have not done so yet as this generally cures most issues.
Hope this helps.

Thanks for the reply but I can sync using Bluetooth connection and did not changed any settings since I got everything working almost a year ago.
Anyway, I just solved the problem. It was hardware related. I found a bent pin on the device USB port. Whith needles and some patience I could put it back to its place. Now everything is working fine again.

I had the same problem sometime ago. I've changed the wire first but nothing happened. My speaker, my Mic was dead and I could switch on FMRadio without the Hands-free!!!
What I did...??? I updated my mobile's Radio with 3.39.90 Version. How can you do this without active sync???
1. Remove SIM Card and Storage Card from the Mobile.
2. Press and Hold the Right Button (Recording Button) and Press together the Power Button. You will be in the Bootloader Screen. Try to update the Radio first.
3. Check it if it's working ok.
2nd way...
1. Copy the official ROM of WindowsMobile to the Storage Card.
2. Press Right Button (you know the Voice Rec) and holding that press the Power Button...
the mobile will be bootloader mode and will try to install the official ROM from the Storage Card...
wait a bit and then when it finish, check it if it is working properly!
Hope to help... waiting to "hear" sorry, to read good news

[Q] BIOS locked on Vensmile W10!!!

I have a TV box whit Intel atom z3735f quad-core, 2GB di RAM and 32GB of memory, HDMI, two USB, battery internal, bluetooth 4.0, Wi-Fi dualband(2.4 and 5ghz), preinstalled windows 8.1(i think 'RT') whit Bing, charge whit another micro-usb port!! Model name: Wintel Mini iPC002 (Vensmile W10) Producer: Vissontech [search it for other features] it's a good product for good price!!
Initially i have a problem whit the two USB and i think that it was disable on the bios setup. I procure an otg cable and connect the keyboard in a micro-usb port to finish a pre-configuration of Windows. Then i reboot and enter in the bios setup. Whit my big surprise, everithing is enable!..then reboot and try the two USB, but nothing: don't work!
At last, i re-enter in the bios setup and i can't select or change nothing!..I repeat the operation but i can't change nothing in the bios setup and the two USB don't work!!
Do you say me one way to reset the bios?..or one solution for the problem that i described in this post?
Exist a tool to flash a bios in WinOS for this product whit Intel processor?
Thank you for your time!
Hope in more reply
Best regardes
Soon.
Same problem
Hello novellus2014, i have exactly the same problem : the 2 USB ports doesn't work.
I have test 2 mouses and 2 keyboard. The led on the mouse don't light. Same for the led on the keyboard (caps lock...).
So perhaps there is a problem with the power on the USB ports ?
I can't finish Windows 8.1 install, i am blocked on the language selection of Windows 8.1.
To finish the install you have use an OTG USB cable on the mini USB power port ??
Thanks to send me a message if you found a solution for the USB ports. I'll do the same for you if i found a solution...
a friend!!
hi mediapole, luckily or unfortunately, we have a same problem!!
the answer at your question is: YES!!
i use an OTG cable for finish an initial install.
but or use it or charge the mini pc..a bad solution for use this product
also in my opinion the problem is the power of USB ports!!
also the led of my pen drive is off when it is attached!!
i have send a mail at vissontech and wait for response.
Soon
Same here
Just received my unit and have the same issues and the same oppinion. I think it is about not having power on those two USB ports, maybe a hw problem? I hope not.
I guess I will try to power the unit through the micro usb port, and I will use a bluetooth keyboard and mouse, and a big SD for storage
I am sending them an email too.
are you able to find solution to BIOS issue?

I bought it through Aliexpress. I contacted the seller and they sent me a new firmware that I was able to update into my device. Still the same, no results, both USB's are just dead, there is not even power on them.

I suggest you should try update your BIOS... Guleek i8 has the same hardware configuration...

Thank you very much. In fact it seems to be an older BIOS (Vx5_bios_20141231_2117_logo.bin) than the one the seller sent to me (Vx5_bios_201501271131_intel.bin), but still I have given it a try.
Still the same, well now I have lost the conection with bluetooth mouse and keyboard, but I guess I could pair them again if needed.
Now I am waiting the dealer to pay me a 50% of the shipping costs back to them. I have 30 days to return the item.

Thats bad... I think its because we tried to downgrade the BIOS from higher version. If you reflash the new one it should restore the bluetooth functionality. If possible could you please send (email) me the BIOS you have?[Vx5_bios_201501271131_intel.bin]
Also, see if this helps...
https://www.raymond.cc/blog/how-to-reset-remove-clear-or-reveal-cmos-bios-security-password/
Sure I can send the BIOS. Is your email published? I can't see it.
I agree that upgrading it again bluetooth should come back, I need to find the uUSB to USB cable again to do it.
I will also check the link you sent, but don't you think that after reflashing the BIOS, USB ports should get enabled if they weren't?

If its a hardware issue then whatever we do it will not get enabled. What i do is i use RDP to this MiniPC if I want to change the settings. That way i dont have to physically connect keyb and mouse to it. I have installed Plex server on this minipc.
I have sent you PM with my email address.
Similar to what I planned at the begining with bluetooth mouse and keyboard. But I'd like to plug my 3Tb disk to it and still keep powered. I have also done some tests with usb hubs, but again no way.
I have tried few things on my mini pc
1) Disabled USB Legacy mode in the BIOS and restarted. flashed the Guleek BIOS BIN file, it flashed successfully and restored BIOS defaults.
2) I have again Disabled USB Legacy mode in the BIOS and restarted. flashed the Vensmile BIOS BIN file, now i cant go to BIOS anymore, it seems it doesn't restore the defaults. I then re-flashed the Guleek BIOS and it started again.
Hi!
i bought 2 days ago a vensmile ipc002.
Im trying to boot with linux usb key, but i have big problems in disabling secure boot...r u able to do it? can you help me?
Everytime it boots windows, even if i made my usb key with rufus, gpt partition, fat32 and every thing i read on the web.
The only way i won is to press restart+shift, then boot/rescue from there by uefi usb....in that way, my pc boot with linux (mate in this case, 64bit version).
Please help me to understand something in bios setup...it seems all disabled, but it everytimes boot windows instead of uefi usb key!!
i tried every solution without success.
I can boot anything ... only win8.1 .
I need to boot linux....is it possible?
Is it possible to flash a different bios without secure boot locked (i disabled from uefi setup but without success...)
Thanks a lot
I have also tried booting with other OS but didn't worked. I will need to investigate more, i will do it this weekend and let you know.

Working Solution for the USB Ports!!!
Hello,
i bought this device last week. and the USB Ports was not working.
so i searched through the Forums, but no solution.
the Solution i found out is, that you have to remove the black Stickers on the front and on the back.
under the Stickers there are 3 Screws on each side. on the front is the WLAN Antenna!
just remove the front plate... pay Attention of the Cable from the WLAN!
then press the electric out to the back side!... disconnect the WLAN Antenna from the Mainboard.
i removed the 2 screws from the USB Port and ... the cable was not connected to this circuit board!!
i removed the Battery (the cable is sticked to the battery) ... pulled the cable to the direction of the USB Ports. and connected it to the circuit board...
then the USB Ports are working!!
just Reassembly the Device after this procedure and all is working
Thomas
Thank for the instructions, if you could post some more pics of the screws (locations) and inside the product it will be great.
I did not wrote this, I found it on Amazon review of the pc.

USB Problem and Solution for the Vensmile. If you are like me you plugged in your Vensmile and were unable to do anything with the plugged in usb keyboard and mouse. There was no power on mine, I checked with a voltmeter and it was dead. I knew it was powered up since it was coming up with the install for win 8. If you are having the same issue as me you will not have a light between the two usb ports in the back. I carefully peeled the plastic protector off slowly (black side with all the ports). This is a piece of plastic held on with sticky tape. This will expose the three screws. Remove the three screws and the main board will slide out. Mine required a tap on each side to start sliding out. You can see the usb board now and just flip the right battery back off the board. I have attached a pic. You can see it either fell out during transmit or was never attached in the first place. Pull up on the black ribbon connection, slide in the ribbon cable and lock the black ribbon connection back down. You will see the usb come back on right away. Slide it back in the case, attach the three screws and put the plastic stick on cover back on.
(I have image of the insides, but the forum don't let me post it)
Edit:
I did it! OMG I did it! It works again! Thomas_Eder and Brittany Thomason thank you so much guys! You are awesome!
1. Use knife to take out the back black bezel. I started from the side and pulled with fingers. Its tough dont worry. It got no scratches.
2. Remove the 3 screws.
3. Tap Tap Tap and the motherboard slide out.
4. On the bottom where the battery is you will have to detatch 2 screws to remove the usb board.
5. See the white ribbon next to battery. Thats it.
6. There is a small cap on the ribbon connector, be careful, open it with nail from the back of his entry.
7. Push the ribbon and close that little lid to hold it in place.
(The usb board will start blink)
8. Dont forget the 2 little screws.
9. Put all inside (watch out for the antenna and ribbon cables).
10. Test. Close. Enjoy.
I made some pics but cannot post them.

I made video with the pictures on youtube - watch?v=OI55cAELoSo

RK3188 JY 3g problem

My rk3188 jy unit has a weird 3g problem.If i drive 10km or 300km my 3g conection works as it should(perfect).If it looses the signal it automaticly reconects when the signal becomes availible. But if i park in a garage where i dont have a signal and i wake up the unit from sleep i dont get any signal until i do a full reboot.
Has anyone have the same problem and knows how to solve this?
Instead of doing af full reboot try turning Wifi off and then on in the settings menu. That works for me if the 3G connection is lost. Disconnecting af reconnecting the 3G Dongle also does the trick but can be impossible if the dongle is behind the dash board

I have similar problem but on boot. Sometimes the dongle is there and connects and sometimes not.
If i reboot immediately then it connects ok.
(once connected its rock solid and is always there but its hit and miss whether android sees its at boot up time)
Anyone else?
Is there a script to prolong checking for the dongle or something?

Ive got it plugged into a Y cable now and using both rear ports. (No difference)...I dont think its a power issue since ones its running it never drops out.
Only seems an issue on initial boot.
Ill try front USB port and let you know if any difference
(Not really a solution though since who wants **** hanging out the front)

Could you try connecting the Y-cable to an external USB power supply and se if that helps. I dont think using 2 USB ports on the unit would make any difference if its the USB Power from the unit thats not strong enough.

Ok front USB port makes no difference.
Apps to turn off 3g data and back on make no difference.
Its seems to be, if the dongle isnt seen at start up then its not usable until you reboot or physically disconnect dongle and re-insert.

Carperformance.se Uconnect Android system help.

I am hoping I can find some help in here with a couple problems I am running into on this system that would make it so much better to me.
The system is basically an Android box utilizing the touch screen and monitor of my Uconnect 8.4 head unit. The naming in the settings is rk3188 and is running on KitKat 4.4.4, so it is some variant of the Android TV boxes. If there are other specs or info that are needed to help in possibly fixing my issues please let me know.
Issue 1: although not major, there is no option to have OK Google from any screen. Having this option for a car system is obviously something helpful. In the settings of the Google App trying to access the menu for OK Google detection doesn't work, so I can't even get to the screen where that option lives. I have the most up to date version of Google App and Google Play Services. I have Google searched on ways to fix this but nothing has brought that ability up. I know Android version 4.4.4 was capable of this. There was another app that utilized Googles voice engine and allowed this function but Google made him stop using their servers and killed that as an option.
Issue 2: this is the biggest bother to me and I could not find anything even related to what's happening in my searches. The system comes loaded with some apps and using Launcher3 for its front end, it has big buttons but offers almost no ability to customize it. The bottom row has apps that you cannot switch out to anything else, and 3 of them I will never be using. The system works but is not as nice as it could look or function. The obvious answer is to use a different launcher which is where the problem arises. I have tried to use Nova and Apex so far with the same very frustrating outcome. After the install everything is great, I can set the screen up to look amazing and add icons and functionality that really make it a great experience. So everything is working lovely then I shut my truck off and go do whatever. The next time I come back I start the truck up everything loads fine, the new launcher and everything I did to it is working just as expected until about 5 minutes in the screen goes black for a second and then the system goes through a factory reset. Really? Are you kidding me? The first couple times I thought maybe I hit something because I hadn't fully put my truck back together but after playing with it more and having the system factory reset 5 other times I have concluded it is related to changing the launcher. I tried Nova first, then I tried Apex with the same outcome and same sequence of events. Obviously it's annoying everytime testing this because updating and reentering my info everytime just to try the launcher again is time consuming. The last test the only thing I did was a different launcher so that has to be it, but why and how can I fix it?
If anyone has any clue how using a different launcher would cause a factory reset to happen please help me out. Or if there is anything I can do to this system to prevent that. My last resort thought would be to root it but I read someone else who has this system that rooting it caused screen layout issues and made things go 90 degrees off? The loaded apps in the system have touch screen calibration and screen resizing which might be necessary for this to function with the monitor.
Thanks for any help.
I spoke with someone else that has the system and they are not having any issues with running a different launcher so something happen to my particular device. I contacted the company and they will be getting me the firmware to refresh it and hopefully that fixes the resetting issue.
i am looking to get this also. I am very curious how you like the device - it looks great though a bit out of date. Waze & email should work well. How much storage does it have? Can you add a sd card or something?

I'm getting a new unit sent out, it seems there are 2 versions and for whatever reason mine wouldn't let me customize the launcher.
But even though it's outdated, every app I tried worked just fine, they still install the latest versions. The system has 8gb of on board storage and a microSD card slot that is mainly for loading maps for offline navigation. I think you can still access it for other uses, but they have a better option for that. There is a USB input for flash drives or external drives. I tried my 2TB external drive on it and it accessed my movies fine from it.
How did you get it installed? Who?
got any pics?
Actually I would be interested in this too, I have an Alfa Romeo and the Uconnect 6.5 (european version) which isn't that great, it would be nice to attach a sort of box with ARM hardware running on Android and using the display and touch of the existing Uconnect. The question is, how this can be done?

I would check out this thread. It has two videos that walk you through the entire process - great info!
I also bought this latest Android system V4 2 weeks ago. Auto launcher pro app is very good working. At the moment there is a issue with the system time, which is not correctly synchronized with gps time. Carperformance Team is working on a fix for that. How can I get root Access for this Android 7 System?

glad to hear i'm not going crazy with the clock but there is an issue.
I just bought and installed a V4 a couple weeks back too.
i must have left a loose connection cause i keep having to recall the touchscreen for android. I half-arsed the install cause we were leaving for a 2k mile roadtrip the next day- need to take it apart and do it right. Luckily you can connect a usb mouse in to trigger the calibration app.
id also love root- at the moment im trying to figure out if the one usb port is safe to connect an A to A usb cable into to get ADB. apparently on some versions of nvida sheild, you can. If they provide a firmware update for the clock fix then maybe that gets us an image to futz with for root.
a keyboard also works in teh usb port and i've tried a handful of key combos during boot to get to recovery but haven't stumbled on it yet.
I'll post back if i find anything

Hi @michaelk
Good to hear that I am not alone here with this special system V4. Except for the issue with the system time and no root access, I am fully satisfied so far. I hope to fix it soon. If we had root access then we could solve this issue with the system time with some time apps ourselves.
Thank you for your experiences.

wiring harness investigation
so played around some today.
I've got an issue where I need to recalibrate the screen almost every time I boot. it seems the box (or card added to the radio?) forgets things and only works the bottom right corner and also seems to rotate 90 degrees at boot. The end result is unusable screen. I think carperformance is just a reseller because of their response. They're friendly and reply quickly but are really unable to help. The first answer was just randomly fiddle with screen and try to find calibrate setting and reboot- that proved impossible and on my own I discovered a 6 dollar USB mouse from the Walmart could be used to navigate to the calibrate app. When I inquired again when it got more frequent they basically said it's not normal and offered no help except to adjust a personalization setting to run calibrate on boot- that only works once that I can figure (might be related to weird time bug)- so I settled on having tasker run calibrate on each boot. I wonder if there is a battery in the box that needs changing but the warranty sticker keeps me out for not- might add an external battery to keep it alive for a longer time to minimize the rebooting
Anyway took everything apart today to double-check and can't find any connection issues. I traced the harness a bit to try and understand a little and basically, the skinny cables run the daughterboard to snag the screen output and the touchscreen input. But i wanted to figure out what is tapped from the radio harness to the large white plug on the box and see if anything going on their .
DISCLAIMER- I NEED TO CONFIRM (it was hot - laughing) but basically seems what is tapped in radio harness is:
1) power and ground also
2) L&R aux audio signal- interesting here is they tapped a single ground (physically next to the right signal) for common. Earlier i had the RAX hack and their harness used a ground for each L&R and their aux input worked all the time without the little plugin shunt thing to trick aux input. When i dug some more and found a pin diagram from mopar I found that the 'left' ground is actually labeled "aux audio device detect signal" I need to play some more to see what happens but my guess is if we put a switch on that to short it to ground then the aux would just work to avoid the hokey plug.
3) Here's the fun- holding the screen to flip inputs could be the daughterboard running things. BUT since it also reacts to the left steering wheel button pack and switches inputs itself when you need the reverse cam- i figured it reads the can bus. and sure enough, it looks like it taps CAN IHS (+) and CAN IHS (-). Very cool that it would get into the whole bus and read anything- BUT since there are other FCA vehicles that don't auto-switch inputs on revers and they have alternate connections it seems the real dev is not involved to update things to sniff for other reverse signals. Reading around here- seems that there is probably a custom serial port someplace in the box that reads this and there's probably no documentation for us to do anything ourselves. But one can hope...

glad to hear i'm not going crazy with the clock but there is an issue.
I just bought and installed a V4 a couple weeks back too.
i must have left a loose connection cause i keep having to recall the touchscreen for android. I half-arsed the install cause we were leaving for a 2k mile roadtrip the next day- need to take it apart and do it right. Luckily you can connect a usb mouse in to trigger the calibration app.
id also love root- at the moment im trying to figure out if the one usb port is safe to connect an A to A usb cable into to get ADB. apparently on some versions of nvida sheild, you can. If they provide a firmware update for the clock fix then maybe that gets us an image to futz with for root.
a keyboard also works in teh usb port and i've tried a handful of key combos during boot to get to recovery but haven't stumbled on it yet.
I'll post back if i find anything

So the spec for the chipset for the V4 says it can handle an OTG port and a couple (maybe 3?) other USB ports. Obviously, the box only has the one USB A port visible on the pigtail. I wish we could get in the box and look for a header for the OTG port to help rooting but.... the darn warranty sticker.
on the FCA/Dodge side of things- I have a Durango with a USB port and SD card reader in the dash (USB Media "Hub" Apparently, FCA uses USB Mini B connectors to interconnect all the ports and the radio. They use latching connectors that are keyed but if you undo them there's a standard USB mini B in there. They do some odd male/female things so you have to pay attention to where you undo cables, but bottom line you can undo the connector on the back of the dash's USB port and stuff a USB mini B female on it and connect it to whatever host device you want.
I first tried an old laptop in case there's anything weird going on. My Dash "Hub" actually has 2 mini-B connectors and a multipin auto harness. Without the harness when you connect it to windows it sees a USB Hub, but the USB port was still dead. So I assumed it needs power from the harness on the back of the dash hub and connected that. UP popped up a USB mass storage device which I believe is the SD card reader- didn't get around to confirming and then the USB port also comes to life. Knowing that it was safe at that point I connected it to the USB A Host port on the box and presto chango now I have the in-dash port connected to the android tv box without any exposed wiring.
Connected the "android auto dongle" through the cars USB port and that works perfectly. I ordered a used 2 USB dash hub from eBay (later model years have 2 and will see what that does. The pictures of that also show the 2 mini B ports- I'll play some more when I get that. I'm not sure what is in those dongles but from the other folks hacking android auto into older models (by using newer radios) apparently, one port works for android auto and the other doesn't. The scuttle is its a body module programming thing but I wonder if maybe there's something physical in there and so the dongle won't be necessary any longer with the new hub? My other thought is if the two USB min B jacks allow you to connect to 2 different hosts- I would try one on the original Uconnect (in case I ever need to update the software) and the other for the android TV box.
So apparently the android tv box handles hubs just fine. As I mentioned earlier it handles a mouse or USB keyboard fine. Also, I played around and connected my hotspot by USB instead of wifi so the device sees it as a modem and that works just fine- so I assume a USB modem works out of the box too. (again odd if that works that carperformance sells a hotspot and not USB modem- like they don't know what the box can do)
I disassembled my display 2 times until it worked. After the first start, I had a black screen. I thought that was it... After 3 times it finally worked. I also had a cable on the plug which has easily resolved. I think you will also have a loose contact somewhere. One time I also had the display calibration gone. Then I connected my old usb keyboard and could then start the display calibration. I reset the system before. So far, the system works without problems. I also have a passive 4-way usb hub to connect.
I have already connected cables for the frontcam but have not yet moved into the engine compartment.
In the video tutorial of Carperformance, you can see when you switch to drive, the display then changes to the frontcam or signal from the cam, but the display does not change to the Frontcam signal with me.
Do you have with you the signal on the display of the camera when switching to drive?
Adw2 = bad mix
Went back and forth many times in email and turns out my calibration issue was probably all ADW2 launcher, guess it conflicts with whatever app they use to communicate with the display.
in the process of troubleshooting I got the update zip for the current version but I don't think those have recovery partition in there and so can't help root? I need to read some more.
I've ripped everything apart like 12 times with the screen, so that my front cam is not connected right now. For the brief time I had it, it was connected to one of the smaller video in pin connectors and don't think it worked in drive by itself, but can't really say for certain. I think certain models can't get the canbus command to see reverse and if I understand they connect in to the video in on the main connector and then use a point on the car that is energized to trigger the switch on that connection. If your adventurous they seem to have to flip a dip also. I think it's the Cherokees or maybe grand Cherokee so maybe Google their thread's? This site gives connector pin outs
http://connectors.dcctools.com/home.htm
There might be a lead for the drive on your shifter if lucky. I think I read the reverse shoulder comes from a body control box in the passenger wheel well?
Also they're super friendly and never wrong when you email but they can be brief. So you could ask if there's a dipswitch to flip to enable auto switching one of the inputs. Hec maybe we should just ask for a table of where the dips do...
(Sorry for any typos... Will try to edit later)
Supposedly it is enough to connect the extra input cable for DVD or CMMB. That answered me Carperformance. Before, I had no external input cable connected. That's why no signal came. The OEM rearcam works flawlessly.
Also, I forgot, they have a workaround for the clock bug
For the clock there is a fix

It's a cheaper fix but so no solution. Carperformance should offer a software update with root access. Then we would be satisfied. We should expect it for the money.
My frontcam is working now good.
You already tried Android auto? Which USB dongle do you use? Do you need a special app for this?
My China usb dongle does not want to connect properly with my oneplus 6T.
Edit:
Android auto is working with Pumpkin USB dongle and autoplaybox app. The noname China scrap goes back to shop.
The time fix is working until now also. Thanks for this info. The carperformance, they wrote or informed the affected people who ordered it. I did not get any info.

besides powering your camera and connecting the yellow RCA video signal did you have to do anything else?
something with the red signal wire maybe?
I cant consistently get a signal on my front cam and not sure if the camera is bad or my setup

few other notes for others-
FCA "aux audio device detect signal" harness line is actually normally closed (I think shorted to ground)- if you break the connection the oew radio flips right to aux in. make the connection again and it flips back to previous input.
the in dash usb port is infact a powered hub. I originally had a usb + SD card combo and replaced it with 2 usb port and works fine. FCA uses mini b connections to it- just use a usb a to mini b cable to connect it to the android auto box and your indash usb port(s) will work on android auto (And provide more watts to charge your stuff). oddly either dahs hub has a second usb mini b connector that i played around with a little but never could figure out what it does
more can bus fun! - i updated the dongle firmware on the android auto dongle sold direct from carperforance and now it has a beta feature to map buttons. somehow it seems to be sniffing the canbus through the android tv box. it has arrow keys, numbers, enter, etc and you use the app to select the input to assign then you press the same button on the car twice- it sniffs the signal and assignes it. I My durango has the button packs on the steering wheel and i was able to assign up, down, left, right and get it to have the android auto respond. Need to play more but i think it actually goes android wide. For example i think the down button on my steering wheel was sending page down to the chrome browser i had open on the box. Pretty cool stuff if they expand that.

Wifi problem after screen replacement

Hey guys,
After I broke my display a few weeks ago i bought a replacement screen + digitizer and repaired it. I also changed the battery. Everything worked fine afterwards.
Mobile connection, gps, speaker, camera, fingerprint reader, everything. Just the wifi doesnt seem to get a propper signal.
I have to stand right infront of the router for it to find the connection and even then its not stable.
Before the repair everything worked fine. I guess it has to be a problem with the connection from the wifi
module to the antenna? But i cant seem to figure out where the contacts are to check.
All the pins at the backside of the motherboard which connect to the battery case seem alright.
I looked for this problem on and I found a few people who had a similar problem but no solution
other then clearing the network cache or factory resetting which didnt help for me.
Another idea i had after looking for a solution for other phones aswell was that I might have accidentally switched 2 screws around on the upper motherboard because some of those create a connection aswell right? Gonna look at them the next time i have time to open it up.
I have oxygen with twrp and rooted it with magisk if that information is needed but i dont think its a software problem because it was working fine before.
Thankful for any kind of help.
I had some time opening it up again. All the right screws are in the right places and the antenna cable is also plugged in correct on both sides.
Any help regarding where the wifi connects to the antenna at the back of the phone or help in general?
Thanks already
Same problem on my OP3T, I've only opened it to replace camera, earpiece and loudspeaker.
Also bluetooth does not work and GPS is slow to get position.
I don't know what to do. It seems an antenna problem.
Any idea?
