Anoyone found a working 4g modem for the Head Units.

I'm using a Huawei E3276s-920 I switched the mode from ndis to modem in the latop and disabled the pin on the sim card.

Connected to a MTCE-GS with Android 9.

The unit sees that I pluged something into it but does not recognize it.

I installed PPPWidget and the widget recognized it and connects automaticaly. Recovers with no problems from sleep mode or ACC off, doesn't have roaming problems.

Recovery from sleep mode to connected 45 seconds

I've been using it for 3 days now with no problems.

The only thing with this is that when I enable the connection sharing hotspot on the unit the unit looses connection but those that connect to the units hotspot do have connection.

MANY USB-STICKS WORKS AS ethernet-simulated device or WiFi-Simulated.

ONLY if android reconize a REAL mobil connection, android is behaving cautiously with the traffic data.

And that is the reason for this thread to find working 3G/4G devices.
[MTCD Android Head Units General] lennylen:
Android behaving cautiously with traffic data? Can you elaborate? You mean more conservative in data usage?
[MTCD Android Head Units General] Rawb1:
Ok so I read the first post also, where you listed working 3g devices. Have we managed to find any "true 4g modem" devices? In Norway 3g will be phased out soon....
[MTCD Android Head Units General] lennylen:
What's the downside of the simulated Ethernet device on Android?
[MTCD Android Head Units General] snakedoc73:
For example: every CLOUD-CLIENT app recognizes a mobile-data or a wlan connection. when a wlan connection to a 3g router (or 3G-to-wifi stick) is connected, the android behaves like in a normal wlan > full data-transfer without limitation. therefore it is important that the correct connection type is recognized by android.

see post 113... same scenario
[MTCD Android Head Units General] snakedoc73:
sorry, no 4g-modms available at tihs time, but a chinese manufactures is coming up with a lte-modem.....

are you sure the 3g/GSM-service will be phased out ??? every car-emergency system will not work any more.......

/chris
[MTCD Android Head Units General] Rawb1:
Ok. What manufacturer and Do you know any ETA? Btw has anyone tried the 4g modem that Dasaita sells for their devices?

Regarding 3g, I don't know about these emergency features you mention but all the biggest telecom companies are phasing out 3g towards 2020. Typical Norway...we don't have National radio(state owned) or commercial radio on FM either anymore. Only local stations. ;)
[MTCD Android Head Units General] ricalv1:
Hi, I've looked at the models dasaita is selling and they are WiFi routers, not modem's I have one of those and you put a sim into the dongle and it shares the connection over WiFi

Trying to get my hands on an E3131s-1. All I kind find is the E3131s-2.
[MTCD Android Head Units General] Rawb1:
Anyone tried the Huawei E3276?
[MTCD Android Head Units General] ricalv1:
I'm trying out the E3276s-920, I have managed to get it to work using PPPwidget, Android 9 detects that something has been connected, but doesn't detect it as a data connection, with PPPwidget in modem mode everything works except Google maps and Sygic can't detect internet connection witch is strange, Spotify, chrome, weather and TV apps all detect the internet connection.

I think it's something to do with the VPN that PPPwidget creates.

Setting the E3276s-920 to NDIS mode I haven't been able to make it work at all.

Im planning to replace my stock HU with daisata px5 but want to confirm first if it will work on my reverse and lane watch camera..My modem is 3372 which is converted to stick firmware and it will offer NDIS mode(network card)..and its working on my routers(pfsense ,ddwrt and openwrt)..only need to load the right kernel modules to work..anyway I will report sooner after I install it on my car....
[MTCD Android Head Units General] Rawb1:
I'm interested in knowing how to use the e3372, so if u get this working that would be great. Will you need to root? What does it mean u converted to stick firmware?
[MTCD Android Head Units General] jefbuan:
3372 has two modes , Hi-link firmware (22.XXX) and a modem aka stick firmware (21.XXX)..in HI-link the modem acts like a router while in stick mode it will act like a modem using PPP or NCM protocol ..with this you will avoid double nat issue , means you will get your ISP IP directy on your interface..
[MTCD Android Head Units General] Rawb1:
Ok thanks for explaining! Looks like I have 21.xxx firmware so that's good! Let us know how you get on!
[MTCD Android Head Units General] jefbuan:
NP..if you know how to acccess your HU system logs after you insert you modem ,please send it to me..
[MTCD Android Head Units General] AndroidAutoShop:
Do these work without connecting via wifi from the headunit?
[MTCD Android Head Units General] Rawb1:
Yea I don't have root on this unit yet so I don't think I can get those logs...not that I know at least. I am looking into rooting but so far I haven't found anyone that's done it without complications.
[MTCD Android Head Units General] jefbuan:
no worries..anyway I'll download this android x86 and put in on my vmware and let's see how can I do with this stick..
[MTCD Android Head Units General] Mickygnt:
I don't get it, why don't most 3g/4g devices on these units, mine knows its there and displays signal strength and Telstra network but refuses to use it, whats the difference with the ones that do work, is it the radio firmware/hardware or dongle hardware. I feel its the android firmware or hardware as the dongles obviously work on other devices
[MTCD Android Head Units General] lbvf7:
Hello to all. As i can see we don't have WORKING REAL MODEMS (detected as mobil-connection) with LTE support through usb (Huawei E8372 for example) . I'm curious about reasons for this. On what level we have lilmitations? Maybe we need modem-specific rillib.so and/or modem specific usb driver? Which rillib.so we have on stock/manufacture firmware for px5/6 or we have just default /refs/heads/pie-release/reference-ril/reference-ril.c and that's why modems behavior so unstable?

Huawei E3372h-607 -Works!!!

Huawei E3372h-607 -Works!!!

Hi people!!, I've been testing the E3372H-607 modem with modified firmware all summer, it's an LTE modem. I can only say that it works perfect.

It has an approximate speed of 50mb down and 25mb upload, the unit works much faster and google asistant works perfect without delay. I know it's not a real 3G / 4G, but this one is going great. Wi-Fi is not necessary for nothings, only by USB port. I recommend your purchase.

By the way, I have modified the installation files, I upload the firmware, you decompress and everything is in order of installation.

Install it on donge, NEW FILES ---> https://www.mediafire.com/file/mlnt2e4vyjgbyi4/Huawei_E3372h-607_Firmware_PX5.zip/file

I buy this ---> https://es.aliexpress.com/item/3300...&terminal_id=9b716d6df29b4f20894d2cc9920c5d94

Ordered mod E3372h-607 ---> very important!!!!

[MTCD Android Head Units General] Rawb1:
Hi! Thanks for posting this! I am getting nowhere with my e3372h-153 as it has some firmware that doesn't allow flashing or AT commands. Now this might be an option. Only thing is I have the PX6, so i guess it's not 100% certain it will work.

Btw your links to AliExpress don't work. :(
[MTCD Android Head Units General] OpperNoE:
metoo, is there also not a big difference with Android 9.0, as it seems all the usuals bugs are gone (like the need to reboot to enable WIFI again). My wife was a happy person this morning after updating to 9.0 (px5). The only thing missing now is LTE.

Could it be that we need additional software, like the Google SIM Manager. My pixel phone is loading/updating that too
[MTCD Android Head Units General] kebul:
Works as a network card...
[MTCD Android Head Units General] juankaxxi:
Yes, but much better than by wifi
[MTCD Android Head Units General] Rawb1:

[MTCD Android Head Units General] gaos74:
Hi guys

I have bought a Dasaita Max6 PX6 4gb/64gb headunit with Android 9.0

I have a data plan with unlimited streaming which does not apply over tethered wifi connection. Therefore I need the SIM to be recognized as mobile connection by the headunit.

Has anybody tested the surfsticks mentioned on page 1 on a PX6 unit?

Thanks in advance!
[MTCD Android Head Units General] Rawb1:
Great thanks! I have ordered one of these now. Just had a look at the folders in the zip you provide. It all looks good but in folder 7 you have adb.exe - what to do with this? Surely that is a command line exe that needs commands to work? And also what to do with DC unlocker? Would be good with a little readme help file! ;)
[MTCD Android Head Units General] lennylen:
Doesn't android automatically recognize mobile data connections fed through wifi/network cards? Is there any real evidence that android consumes more data when use this way vs modem connection?

I only say this because, when i hotspot my phone to the headunit, certain downloads/uploads say "waiting for wifi" , even though it's connected through wifi... Usually have to force the download/upload to continue..

Google Play seems to respect this as well.. my apps will not update by themselves despite having "auto-update" enabled.
[MTCD Android Head Units General] juankaxxi:
In folder 7 there are 2 .bat, one to install and another to uninstall. Use install.

DcUnlocker is useless, I have put it in the pack so you can check the modem ports
[MTCD Android Head Units General] Rawb1:
Ok great! I missed those. My bad. Hopefully this will work on PX6 also.
[MTCD Android Head Units General] juankaxxi:
Ok! please confirm that it worked for you when you receive it.
[MTCD Android Head Units General] Rawb1:
I will. Should arrive in a week.
[MTCD Android Head Units General] homer.ali:
Fyi folks just managed to get zte mf833v working with xtrons gs px5 Oreo with actual 4g, NOT RNDIS ethernet (see attached pic)

The way I did it was to place the modem into non-usb mode so that it shows up as a cdc-gsm device.

1: download DC unlocker on your windows pc (this is to get the modem to show up as a COM port)

2: plug your modem into PC and launch DC unlocker as administrator. Select zte modem from the list and leave the rest of the fields on the default auto select. Hit search

3: open up device manager on your PC and look for ports and you should see two COM porta for your zte modem each with a number next to them. Take note of the number next to the one that DOESN'T say diagnostic on it.

4: download PuTy or any other terminal program of your choosing. Connect to the aforementioned COM port using serial connect and if it works well you should see a command line window where if you type AT and hit enter you will get OK as a response

5: type AT+ZDCDRUN=8 and hit enter to place the modem into non-usb mode. If it goes well you should get a message saying updated modem mode or something similar.

Unplug your modem and put it aside for now.

6: if you are using an xtrons unit you need two more things. First you'll need the right MCU as the factory shipped MCU does NOT support cellular network. I've attached the one I'm using to this..make sure you update. Second is you'll need a network settings app to actually enter your APN settings. You can find one on the play store but you won't be able to enter APN settings until you plug in the modem

7: plug your modem In ONLY WHEN YOUVE DONE EVERYTHING ABOVE.

If all goes well it should now allow you to edit your APN. Enter it and hit save then restart your tablet.

8: profit

I've done some testing with this setup and it takes on average about 20 seconds from start for the tablet to have 4g internet. I toyed around with keeping the modem on a permanently powered usb port but have not been able to keep the connection stable.

Driving around the tablet keeps data signal and switches between cell towers seamlessly.

I do notice that if I turn my car on and off multiple times in succession that can cause the tablet to no longer see the modem. A simple USB reset when that happens does the trick.

DEAR FRIENDS!

the projekt "Working REAL(!) 3g / 4g USB Modem-Sticks on PX5/PX3 Units" has closed from my side, because the PX5 systems (with ANY firmware and custom roms) shown, that the CHINA build car-audio-system are absolutely CHEAP-CHINA-CRAP (frozen APPS, frozen Systems, absolutly non-stable systems, POOR AUDIO OUTPUT QUALITY, etc.)....

so.... i´m goint to convert a smartphone to a high-fidelity car-audio system.... with a OTG-sound card,buttons,car-cams, etc.... eveything realize with a samsung j7 2016 > great solution at this time WITH 4G ON BOARD. i will open a new thread for this project.

[MTCD Android Head Units General] Rawb1:
Hey that's so good! I have also bought the e3372h-607 from juankaxxis link, but I can't get past folder 2. (Download error 19). Did you just plug the device in and start? Not anything extra? Do you know what firmware was on the device when you bought it? 22.xxx or 21.xxx?
[MTCD Android Head Units General] fredovvti:
Its was 22.00
[MTCD Android Head Units General] Rawb1:
And you did nothing extra? I don't understand why I get error 19 on the first firmware exe.
[MTCD Android Head Units General] Rawb1:
Ok i just decided to plug it into the car as it is. I never managed to update/downgrade firmware. I had ppp widget 3 on the head unit from previous testing with another modem and when I plugged in this new modem everything just worked. It even works with autoconnect at startup. Jeez! All that bother with trying to flash it and it was working out of the box( with ppp widget). Woooohoooo! This has been bugging me for a while and now it f*** works! Just lovely.
[MTCD Android Head Units General] fredovvti:
Good for you!!
[MTCD Android Head Units General] juankaxxi:
Install MobileBrServ_without_service_Setup.exe and try again, if not work chage usb port or restart pc.

Luck!!
[MTCD Android Head Units General] Rawb1:
Thanks, but I tried it without changing the firmware and it works like a charm with ppp widget 3.
[MTCD Android Head Units General] Rawb1:
Ok... I take it all back... I have 1 problem! Looks like ppp widget 3 works with Spotify, chrome, play store etc... But not with Google maps! Which is cind of sucky on a head unit. But i have no luck with your suggestions... I try what u said but stil error 19. Did u get black or white modem from AliExpress seller?
[MTCD Android Head Units General] juankaxxi:
I get the black

Try jump next step important are 2 and 5
[MTCD Android Head Units General] Rawb1:
So strange. I also get black. You are using Windows 10? You mean jump to step 3? It's step 2 that I'm stuck on.
[MTCD Android Head Units General] juankaxxi:
Yes, try it.

If no on folder 1 install and unistall all

Or install folder 1 again --> You install it first??
[MTCD Android Head Units General] Rawb1:
I have installed folder 1 many times all the installers in there.

I tried to install folder 2, 3, 4 and 5. All fail on error 19(download error).

Have a look at the video in link. You see what device manager and ports are doing when trying to flash. It looks like the ports are opened but then closed before it can flash...

[MTCD Android Head Units General] Rawb1:
You are thinking that the drivers in folder 1 are not being installed correctly, because they are maybe unsigned?
[MTCD Android Head Units General] juankaxxi:
I dont know, but please, reinstall all with force unsigned drivers and shutdown antivirus
[MTCD Android Head Units General] Rawb1:

No luck after installing drivers with unsigned drivers mode. Just the same!
[MTCD Android Head Units General] adicrl:
For those still worried about the "real" mobile data connection. I noticed today while connecting to a mobile hotspot that in the network configuration screen (where you enter the password) there is an advanced settings option which allows ticking "treat as metered connection" (wording may vary). This could alleviate concerns that apps would hog the data connection with full backups and what not. I have only discovered it today, so I do not know for sure what it does, but I thought to share the info.

Probably going for a Huawei 3372 now... as I already bought the wifi-only android dash unit :D

Error Code 19 :-

Reason For Error:- Error 19 may caused if the other application or service is using your modem.

is there any update for natively working LTE dongles for PX6 Android 9 ?
[MTCD Android Head Units General] Longlemur:
I have a px5 car radio with android 8.0 with a connected 3g modem huawei e173-u2.

After turning on the radio, the modem does not automatically connect to the network, but just remove it from the USB port and insert it again when the radio is turned on and the modem connects immediately.

What can be the reason and reason for this behavior?

How to solve the problem?
[MTCD Android Head Units General] liamstears:
Thank you thank you thank you!

I can confirm this method is fully working!

Couple of notes, I use a PX5 CSN2 based unit, for me to get this working I had to first connect the modem to a computer before making any changes and connect to 4g, I had to go to the settings page (192.168.0.1 on my unit) and check all settings were correct, for example it was set to use 3g only so I set all settings to either default or automatic and then followed the guide posted with 1 minor tweak

AT+ZDCDRUN=8 is the wrong command (simply a typo by op)

Correct command is:

AT+ZCDRUN=8

Hello,

Thanks for the description! I have some questions.

1. MCU GS 3.17 is the standard or modded one? I have a Isudar HU/Oreo i think i can update MCU

2. What APN software have you chosen/installed?

3. What do you mean USB reset. Plug/un-plug device?

Tapatalkkal küldve az én EVA-L09 eszközömről
[MTCD Android Head Units General] homer.ali:
1) standard. Not sure if it would work with head unit. might cause more problems than help if you update to the wrong MCU

2) https://play.google.com/store/apps/details?id=dogfooderz.com.apnshortcut

3) yes. You can also do it programmatically via shell commands. I wrote a quick tasker script that does this that I can post here when I get a chance.

[General Questions and Answers] SprinklesNSlippers:
I've never before rooted my phone not only because I don't want to, but also because I have notoriously clumsy, fumbly hands. I feel like if I tried anything, I'd mess up severely and I don't just have the money to go and get a new phone.

That being said, there's this specific font that I want access to on my computer and, being blunt about it, it's been driving me up the wall. I've been trying to find downloads of TYPEMemory (a free font from the LG Smartworld mobile store). I'm surprised about it not having any downloads out there - it's a very pleasant font to look at and is free.

Not only do I want this font (an apk, ttf, or otf is okay, I don't mind any of them), but I also kind of want to know if there's a reason for this? Is it because getting fonts off of a phone is difficult? Is there some sort of unspoken of policy in reference to free mobile fonts? The font is free, so inquiring about it anywhere technically doesn't make it piracy, right? It just makes it asking about a font that you normally can't use on your computer. And considering it's free and everything, it isn't piracy because you aren't 'stealing' from anyone when you download it. I mean, I already have it on my phone, from SmartWorld.

If you can help me out, I'll really appreciate it! ...And yes, I did make this my first post on this forum. I'm that dedicated to my font collection. :o
