Same configuration here, doesn't work. What are your settings under "Mod - Hardware" for USB and Ethernet?
[MTCD Android Head Units General] Symour de Bonneville:
Hi there!

I have an Xtrons PX5 (PB78QSFP-B) headunit in my car an now I've got the Huawei E3372h-607 unlocked modem stick.

Software version:	22.315.01.00.74

Web UI version: 17.100.09.00.03

I would like to downgrade it acc. to this:

" Upload to the device from 1 - 3

1. E3372h-607_Update_21.110.99.02.00

2. E3372hUpdate_22.200.03.00.1134_M_HC_ADB_TLN_02

3. Update_WEBUI_17.100.06.00.03_V7R2_CPIO_Mod1.4 "

Constantly having an "ERROR CODE 19" during "downloading programs" and can't find the solution.

- Using Win 7

- All drivers properly installed.

- The updater gets administrator rights

- Force closed all the services which is might be related to the error code.

(HWDeviceService.exe, DCService.exe, MobileBroadband.exe, UIExec.exe)

- SIM inserted, properly functioning.

- In dashboard 192.168.8.1 the modem is disconnected.

If you have any idea what is wrong please share with me.

in my case i have bought a usb huawei e3372 modem, i have tried to connect it via usb and the system does not recognize it as such (i expected it) although the icon of the coverage appears in the notification bar and it shows the real status and it is updated, but i have no way to pass the APN settings to the system, in my case, searching a lot in our beloved internet, i have found an application which allows to receive data from APN's and i can even connect the modem by 4G+, but it is nothing stable and the connection can last 3 hours or 2 minutes. The application I use is this PPP3

https://play.google.com/store/apps/details?id=de.draisberghof.pppwidget3&hl=es_419

Although there are also these other 2, I don't know what the difference is but the result is similar

https://play.google.com/store/apps/details?id=de.draisberghof.pppwidget&hl=es_419

It's a shame I can't get it to work well, because it gets a lot of coverage and when it does work it goes like a shot. Hopefully we can get it to work stably

Hello, I just got the Huawei E3372h-607 and I think I have loaded it. Before it appeared on the PC and now not even that. in installation I got error 10 port not found. What I can do?
[MTCD Android Head Units General] Picuervo:
I have already managed to install everything except in folder 8 it asks me for a modem IP and I don't know which one to put.
[MTCD Android Head Units General] Jeff.monroe:
I made a mistake, no handover working, sorry!
[MTCD Android Head Units General] dape16:
I don't know if I should have started a new thread or not, because I have a PX6 head unit and not PX5 or PX3.

I am trying to use a Huawei E3372h usb modem stick with my PX6 4/64 GB running rooted Hal9k Android 9.

I have tried these steps:

- Using it with stock firmware 22.x (HiLink mode), head unit shows native signal symbol and mobile connections options becomes available. But it will not find any network and no option to connect.

- Flashed different 21.x firmwares (stick-mode) and played with different AT^SETPORT commands, but the head unit does not react when I plug it in.

- After some tweaking with PPP Widget 3 I can connect to the modem and everything seems to work, it will ask for APN and shows signal strenght, but in the last step it will not connect to mobile network.

The modem works fine as a "native" connection in Windows and Linux.

Has anyone else played with usb modems and got it to work on the PX6 platform?
[MTCD Android Head Units General] Rawb1:
I have got that modem and it is stock firmware. Don't remember now what number but the one that starts with 22.x. I have mine working with ppp3 widget. I think I put the carrier info in options of ppp3 widget to get it to work. I can check later what my settings are and send u a screenshot. But one problem with this modem and /or solution is that it's not a fullworthy recognised connection in the android system so even though Spotify, chrome and other apps work. Some apps like unfortunately Google maps thinks it's offline. The same goes for "ok Google".
[MTCD Android Head Units General] dape16:
Thank you very much for your answer. I will try stock 22.x firmware and PPP Widget 3 again. Is the connection displayed as a native mobile connection with signal symbol, or as ethernet-over-usb (two arrows I think)?
[MTCD Android Head Units General] Rawb1:
Mine is just displayed as a key symbol. (Key for locking a door.)
[MTCD Android Head Units General] dape16:
I have tried with a 22.x firmware and PPP Widget 3 now and got it working, the key symbol is there because it emulates a VPN-connection. I had the same problem as you, some apps think they are offline.

I also tried the files in this video:

https://www.youtube.com/watch?v=EaOHIS2gadk

They are for E3372h-607 and I have E3372h-153, but it seems to work anyway. Now when I connect the modem to the head unit it will show up as a ethernet connection instead. They connection speed was not quite as good, but no problem with apps that think they are offline. I can't say anything about stability yet.
[MTCD Android Head Units General] Rawb1:
Hey that's great you got yours working! My problem is I can't update the stick with any updater files like the ones in the video. Either it hangs at finding port or it tries to download but fails. Can you tell me exactly what environment u are successfully uploading firmware? Computer, Windows version, what drivers for Huawei are installed, anything u do like run as administrator?
[MTCD Android Head Units General] dape16:
I had the same problem with the update files in Windows, so I just made a Ubuntu bootable usb stick and did the "needle-trick" to force the modem into recovery mode. Then I used the utilities balong_usbdload and balong_flash to flash the firmware files to the modem. You can use this guide but flash the .exe-files from the YouTube-video instead. I had to flash the webui-firmware twice to get it working.

https://www.0xf8.org/2017/01/flashing-a-huawei-e3372h-4g-lte-stick-from-hilink-to-stick-mode/

Let me know how if you run into any problems.
[MTCD Android Head Units General] Rawb1:
That sounds interesting! Can you direct me to the exact Ubuntu version u used? Also did you do the flashing from Ubuntu or Windows?
[MTCD Android Head Units General] dape16:
I just downloaded the standard Ubuntu ISO-file and made a bootable USB with Rufus. Booted the USB and did the whole process in Ubuntu Live mode, did not install it.

Then I did the whole process in Ubuntu. To clone and build the flashing tools from GitHub you will need to install some additional packages, like "build-essentials" and "gcc".

The only problem I have now is that the modem will power down together with the head unit when I remove the key. It will then take like 20 seconds to reconnect next time you start the car, so it's not possible to continue to use apps like Spotify, Google Maps and Waze straight away.
[MTCD Android Head Units General] Rawb1:
Hi !

I managed to flash the first exe using this method. But trying the second one I get "no response from modem in hdlc mode"

Do I need to do the needle trick and usbdload between every upload?
[MTCD Android Head Units General] dape16:
Yes, if I remember correct, the modem restarted after every update so I had to do the needle trick for every single file.
[MTCD Android Head Units General] Rawb1:
Hmm I'm not managing to flash number 2 of the files. Tried needle trick and without. I get a few different errors. But mostly "incorrect firmware monitor version" and "digital signature verification error -43"

Out to try this now in the car.

Ok so nothing immediately happened when plugged into HU. I tried uninstalling ppp3 but stil nothing. What where your steps here?

Edit: saw u are running hal9k ROM. I am on stock so that might impact things.
[MTCD Android Head Units General] Rawb1:
Ok. So i installed hal9k ROM on my unit since I had planned on doing that anyway.

I flashed the stick with all the files in video. But the stick seems to have lost it's little blinky light. In Ubuntu I can see it registered as a Huawei modem with "lsusb". But when I stick it into head unit, nothing happens. No blinky light and nothing on display in hu or under settings. Did you still need to use ppp3?
[MTCD Android Head Units General] thorte:
Hi,

I also own a E3372h-163 and played a little bit around with it, as it was recognized as an USB LTE stick by the Android system. I'm on the Hal9k rom. I was able to get the stick running with PPP3 widget. The technique behind PPP3 widget is the usb_modeswitch which should be available at least at Hal9k. To get the stick running it has to be switched from the mass storage mode to the modem mode.

What I recognized:

The E3372h is primarily recognized by the Android System with the USB VID=12d1 / PID=1f01. According to what I read on about USB modeswitch (PPP widget based on usb_modeswitch) the stick's IDs should be switched to VID=12d1 / PID=14dc to be recognized as a LTE modem. A "lsusb" on the device outputs a "Bus 001 Device 009: ID 12d1:155e". A "dmesg | grep 12d1" shows me that the

rk3399:/ # dmesg | grep 12d1
[ 432.788811] --mtc ann 1-1.1 12d1
[ 432.788894] usb 1-1.1: New USB device found, idVendor=12d1, idProduct=1f01
[ 433.309544] --mtc ann 1-1.1 12d1
[ 433.309602] usb 1-1.1: New USB device found, idVendor=12d1, idProduct=155e

Seems, that the originally as a mass storage device detected E3372h is reassigned with a different USB mode, which differs from the one which would be uses by usb_modeswitch. I was not able to prevent the system from that reassigning of the stick to idProduct=155e, to bring it into another mode via usb_modeswitch. Seems that a kind of modeswitch is integrated into the system. I believe, if we would be able to prevent the system from reassigning the stick as dProduct=155e, it could be possible to get the stick running as a native USB modem.

Regards Thorsten

Does anyone use the 8372h-153 USB stick?
[MTCD Android Head Units General] themissionimpossible:
Have you seen this site:

https://techship.com/faq/how-to-cha...-usb-4g-lte-cellular-sticks-in-linux-systems/
[MTCD Android Head Units General] thorte:
That's exactly the way I tried to go. But unfortunately the stick is modeswitched to 155e instead of 1506 as described in the FAQ, and I did not found a way to prevent this. "usb_modeswitch" seems not to be responsible so there might be a kernel function which switch the device from "1f01" to "155e". If this could be prevented or undo, there might be the chance that switching the E8372e from "1f01" to "1506" could be a way to get it working.
[MTCD Android Head Units General] Rawb1:
I finally got this working. Flashed the first two firmwares in Ubuntu on a e3372h-607 and it started working in Ubuntu in LTE mode, so I tried in HU and it works! I'm pretty sure it's lte/4g, but can't be 100% sure. See the speed test I did.

All apps work flawless.

Edit: to be clear: I did not flash the last file which is the hilink one. I also have the same issue as you that it takes some seconds to boot up. But this is worth it still.

[MTCD Android Head Units General] dape16:
Thanks for reporting back and I am happy that you got it working. I see that your also are using ethernet over usb-mode, which seems like the only solution at the moment.

---------- Post added at 10:14 AM ---------- Previous post was at 10:12 AM ----------

Thanks for your information regarding this, I did notice the same thing about this switch which seems to be a kernel function. This has been discussed in the PPP Widget3-forums but no solution so far, as I know.

what about px6

Is there a working LTE modem that is recognize by the head unit? I have the Dasaita Max6 px6 chip

and looking for a solution of using wireless Carplay (which is using the head unit wifi) and still have internet access on the head unit itself.

Are you using a px6 unit or px5?

I'm looking also for an LTE working modem for my dasaita max6 head unit so i won't need to use the internal wifi to get internet connection (I need to internal wifi for apple wireless carplay)

(In the setting, it is recognised as Ethernet)
[MTCD Android Head Units General] tlatech:
I have a couple of questions:

1. Which version of Android are you running? Which MCU version? Is it a custom ROM?

2. Did you just plug the Modem in and it worked? Did you change it from stick mode to modem mode. If so, what procedure did you follow?

3. Is it working as a 3G or 4G connection.

I have one of these modems. I am seeing a "Signal Strength" icon on the status bar, but I have no data connection.

Thanks.

No custom rom

Juste plugged and it work I have no signal strength I have Ethernet icon

I'm using a Seicane PX5 HU with Hal9k A9 rom. With the Huawei e160X, original Firmware, it connects to network only after checking the 'roaming' checkbox. Its a 3G Modem Stick, and it offers Data limitation in the Network settings too. Nothing grayed out. Connection stability is pretty good.

The only bad thing for me...if wifi is active,( i use it to connect my OBD2,) it has no 3G data connection, because android prior uses wifi for internet instead of 3G data and awaites data connection over wifi...

ZTE MF833V Confirmed!

Yep I can very much confirm that the mf833v works on T-mobile . I got the custmized version from amazon which should also work on AT&T (and i believe verizon also? - don't take my word for it).

Search amazon for

https://www.amazon.com/ZTE-MF833V-C...child=1&keywords=mf833v&qid=1605635946&sr=8-1

Just follow te instruction by using AT command : AT+ZCDRUN=8 .

If you are not getting internet then, you need to first disable "auto connect" ) on the web interface (192.168.0.1) on windows/Mac before running the AT command.

You can reverse the setting to work on windows again by running command (directly on dc-unlocker command line):

AT+ZCDRUN=9,

AT+ZCDRUN=F,

This will put it back in CD Mode.

IF you don't have a the driver, let me know. Cheers.

I have a Dasaita px6 with android 10 and with the Huawei 8372 4G modem and I only have ethernet and the Radardroid app does not download the radar database, because it does not detect the network, instead Spotify, google chrome and playstore do have access to network.

I got the latest version of dc-unlocker, extracted the zip, ran dc-unlocker2client, and it ****ed with the device and now my Win10 does not see the ZTE as an ethernet adapter anymore.

I have a secaine Android 8 for my tundra. I was using hot spot on my phone to HU. Yesterday the wifi wont turn to the on position. When you click on it, it goes right back to off. I tried network reset nothing. I tried to use bluetooth and usb teathering no luck. It will show paired but no internet. I am thinking the built in modem died. So no matter what i try if there is no active network card its dead. Any idea if i can use a usb dongle modem ? I do not mean the ones requiring a sim i have a phone that worked with the hot spot i do not want another cell service. I am thinking as long as it acts like a router it will bypass the built in modem. The phone provides the service i just need the head unit to receive it. Any ideas ?
[MTCD Android Head Units General] talrhv:
Are you sure that your modem died? Check to see if you have hotspot enabled in your head unit? Also try to disconnect the minus from your cars battery for a few seconds so that the head unit will have no power and reboots itself.
[MTCD Android Head Units General] jaystundra:
I tried the negative cable left it disconnected for 2 minutes to allow system to discharge. No difference. Before this happened i would turn on hot spot on phone then click wifi connect on radio and all was well. Now when i click on Wifi it goes into Wifi settings and shows me the Off button. When i click the on button it immediately switches back to off. I have tried to hold the button for several seconds and no matter what i do will not engage to the on position. The hot spot has worked flawlessly for almost 2 years. There has been no reason to adjust settings as it has always worked. This is why i believe the modem module has failed.
[MTCD Android Head Units General] jaystundra:
just a note i have no sim attached to the radio, the radio is relying solely on the phone hot spot for internet.
[MTCD Android Head Units General] talrhv:
I see. So you are looking for something that will switch your WiFi and be recognized as Ethernet or a wifi adapter. I think that this option can only be done if you have a SIM card on your dongle. I don’t think that there is a way to do what you need.
[MTCD Android Head Units General] jaystundra:
Kinda what i was thinking also. I was hoping that the dongle modems would work as a network adapter and receive the hot spot from the phone without a sim. The sim is so you can use the modem to send internet out. I already have that with the phone. They make routers also so i wonder if a usb router would allow me to connect my phone to the radio. But my gut is telling me that all network activity has to use the built in modem in the radio to even receive a signal from the phone even teathering options.
[MTCD Android Head Units General] Topper59:
Hey I have the same HU, modem, and T mobile. After putting the modem into download mode and then running the AT command, it still isn’t working so hot on the HU. I’ll get basically a split second of LTE and then it will go to no service. I was able to load wikipedia during the second of LTE and it loaded pretty fast, but it loses connection. This is with auto connect disabled in the webui prior to going into download mode with dc unlocker. any ideas? which usb port do you have it plugged into, the double or single? and i don’t suppose you remember what firmware the modem is on lol

What seems to be happening is the modem boots up red, goes to green as it connects, goes to blue for LTE, and then goes back go red a couple seconds after getting LTE. It just keeps repeating that loop

EDIT: Further development, it looks like once it would get LTE signal it would reboot, my guess was the USB port from the HU was underpowered and LTE took more power than it could handle. I plugged it into a powered USB hub and for the most part it holds an LTE connection now. Still kinda flakey though.
