I think they all do that. People have been g splitting the cable for data only to your hu, and power coming from lighter 12 adaptor. Make sure its a good one. (pretty easy if you have a knife and some they tape for a quick fix) .
[MTCD Android Head Units General] Topper59:
Yep, got a USB splitter coming tomorrow and I'll do just that.

So I have an Eonon GA2185 and a ZTE MF820B that is unlocked. Works great on my laptop and with the DC-Unlocker app am able to disable the CD mode and looks like it is correct (lsusb shows it as 19d2:0167, not 0166) and AT+ZCDRUN=4 shows

Inquiry autorun open state result(0:NO 1:YES):1

but my headunit still refuses to connect to it.

I see in your instructions to go to 192.168.0.1 and disable "Auto connect" but I'm not sure where you are doing that.

On windows laptop, it never shows me that IP, only the IP of the cellular network after I connect. Before connection it's not showing an active IP.

Are you using Linux? I popped this into my Pi4 and ifconfig shows the device but with a 169.254.x.x address.

Could you please explain how you are getting to that website at 192.168.0.1?

Or is it just the difference between an MF820B and an MF833v?

I'm really getting tired of using a hotspot/mifi..

Thanks

Can you link the drivers, and is it drivers for Android? I have it working on Windows just fine. Thanks your directions helped me out so far I just can't get it working on my px5

I found this link in the amazon listing for windows based drivers. Not sure if that will help you or not but it was buried in the comments/questions:

Q: Can you customize this zte to work for android radio 10.0? also how to use at commands? i read somewhere that those will make this work for android

A: thanks for contacting us. Yes, some buyer made it work.

It's plug and play or easy manually install in windows, Mac, Linux and chromebook.

If not working on Android, try this driver

Run AT command

The USB Modem has to be preprogrammed to RNDIS Mode (AT+ZCDRUN=8).
[MTCD Android Head Units General] m0nk89:
Also can confirm that the ZTE MF833V works on my stock firmware Audi A4 Xtrons HU (IB80A4AL Android 10/MTCE). Just needed to run the AT command through DC Unlocker and set connection mode to manual in the web ui. Interestingly, I didn't even need to use an APN app, plugged it in and it detected and connected to T-mobile immediately. Using one of my free TMo voice lines (y)
[MTCD Android Head Units General] Topper59:
T mobile might see the IMEI is being used in a modem and stop you, since technically you need a data only plan for it. I changed the IMEI on mine with some of the tools from 4pda.
[MTCD Android Head Units General] stale86:
Thank you for the info, did you know if that method also working on Android 9 ?
[MTCD Android Head Units General] Psvdimension:
I have same problem after trying connect by DC my modem dosent work. In device manager see only USB AT and USB LOG. I cant found drivers. Do you maybe have its? I check on few pcs and same drivers needed 😐 before softer start automatic now nothing. Someone help?
[MTCD Android Head Units General] dape16:
Does the head unit keep the connection to the mobile network while it's in standby? Like a phone. 🙂

Or is it a delay before the connection is available?
[MTCD Android Head Units General] gromsop:
To be clear, your HU have RK3399 PX6 right ?

And it work without any change ?

Just plug and that's all ?

Thanks for your answer :)
[MTCD Android Head Units General] m0nk89:
There's around a 10-15 second delay for the USB stick to power on again every time i start the car. The xtrons unit i have is pretty much instant on, so i just have to wait to use the LTE. i tried actually hardwiring it so that the usb stick doesn't turn off when the car shuts off, but i found that it did not reliably reconnect when the headunit turned back on.
[MTCD Android Head Units General] Apollon2:
What exactly is so special about the customized version. I can‘t find such a version in Germany, only „normal“ unlocked versions at around 50€. Theres also an unlocked version at aliexpress for 25 €. Would these work as well?

Thanks

Alex

update:

Ok the only one I could find is not the MF833V but the MF833T, which seems to fit european LTE-bands. Any experience with that?

update2: I‘m confused. There‘s also a MF833U1 available...
[MTCD Android Head Units General] ojuniour:
Excuse the late reply.. Which usb modem do you have?
[MTCD Android Head Units General] Sorensonn:
Tried Huawei e3372h-320 in my PX6 unit with Hal9k mod, but not working. It is detected, showing strong signal, but connection cannot be established. I couldn't switch it from cd/windows mode.
[MTCD Android Head Units General] Sorensonn:
ZTE MF833V - I also confirm that it works after AT command sent via Putty. LTE connection is only about ~20Mbit (upload/download), but for a car it's more than enough.
[MTCD Android Head Units General] Apollon2:
I haven‘t had luck with my MF833U1.

I was able to put it to modem mode with dc-unlocker and finally install modem drivers for windows (which I had to do manually). I am also able to connect with putty and it accepts the „AT“, „ATZ“ and „AT&F“ commands. but on the „AT+ZCDRUN=8“ command (and similar commands) it shows an error. When I plug it to my car in that mode it doesn‘t recognize it, even no luck with ppp widget3.

In „normal“ mode it works as ethernet device with and without ppp widget3.

I need to amend, that I have a TIM-Firmware version (TIM is an italian provider). Maybe that is the problem. However, I couldn‘t find a neutral one.

Any suggestions?

update:

I‘m quite desperate. I am willing to buy a working stick but I can‘t finde one. I cannot use the MF833V cause it lacks lte bands 7 and 20, which are necessary in Germany. I even ordered an Huawei E8372h-155 but got an -820 delivered which I also cannot switch. 3372-155 is nowhere available. I don’t want to order something in china again just to wait weeks to get something else delivered... That sucks. (Sorry)
[MTCD Android Head Units General] Elchango1:
try "AT+ZDRUN=8 or AT+CDRUN=8" one of those cant remember which one but worked for me

Unfortunately neither one did work. Thank you anyway!
[MTCD Android Head Units General] ojuniour:
I've a vendor who is now selling compatible 4g LTE modem which supports Verizon and T-mobile (and probably T-mobile affiliate networks too).

It works on MTCE devices (idoing devices at the very least)..

I'll post the amazon link shortly.
[MTCD Android Head Units General] mozz093:
Hi there,

No luck for me, I bought the ZTE MF833V on Amazon. I plugged the device for the first time, it worked fine. Before I could install the drivers, the CD mode deappeared and never came back. So I found on this thread a drivers package that I installed. The ZTE software sees the device, it's connected to LTE with a blue light on the stick, but the connect button is grey, I don't have internet with this stick.

DC unlocker detects the devices, but with Putty, nothing. When I type 192.168.0.1, nothing happens too (it worked at the first try, after that nothing).

I'm wondering if I have a faulty device or if it's a config issue. Do you have any ideas? I searched for drivers on internet but I didn't see anything serious

[MTCD Android Head Units General] scrilla:
Looking for a little help on the ZTE MF833V on IB80A4AL. Are the settings applied via DC unlocker supposed to be:

Autorun disabled via AT+ZCDRUN=8

&

Download mode enabled via AT+ZCDRUN=E

?

When I push those changes to the modem, I end up with just a solid blue light, the /_| icon in the top bar of my android 10, but no indication of connection to LTE, like it should if it were flashing blue. Have I missed a step somewhere?

Thanks
[MTCD Android Head Units General] eNubiX:
Mine is doing the same thing... I believe that the solid blue light may be the final result in order for the Android headunit to read it. Is anyone else experiencing the same results? I would love to take advantage of the 4G LTE vs 4G.
[MTCD Android Head Units General] MarinDB:
Hello, thanks to all of you.

After reading your posts, I bought a MF833U1 usb 4G modem for my PX5 MTCE Android 8.0.0 (Official version).

My APN is WEBSFR in France (This is the cause of my english level writting).

I've plug the dongle in my PX5 without PC modifications, and GREAT, it's automatically 100% fonctionnal. With a quickly "ethernet" access.

Sorry because the topic is MTCD, but it's the only topic I have found about MF833.

Just for information:

Before finding this MF833 solution. I had the E3372h-607 dongle with the following patches :

E3372h-607_Update_21.110.99.02.00

E3372hUpdate_22.200.03.00.1134_M_HC_ADB_TLN_02

Update_WEBUI_17.100.06.00.03_V7R2_CPIO_Mod1.4

It was really painful. Lot of problems:

- Disconnections.

- Dongle Reboots (sometimes without restarting).

- Sometimes inactive. (Speed green LED lightning)

- Sometimes inactive because the automatic connection don't start automatically. I had to click on connection button in 192.168.8.1

- Sometimes (rarely) good working condition.

Maybe that my E3372h-607 dongle was in bad condition when I bought it.

Voilà. Thank you.

Best regards.

For those who want give priority to Wi-Fi connection instead of Ethernet (provided by LTE dongle in Hilink mode), I developed an app that shuts down the Ethernet interface when some choosen Wi-Fi APs are available. Thus, the Wi-Fi connection can be stablished. If the Wi-Fi connection drops, the Ethernet is turned on again.

I made it open source so that you can compile the APK by yourself or you can download the APK. You can choose the prioritezed Wi-Fi APs in application "Settings".

Working as real 4G/LTE modem (need ROOT):

Quactell EC25-E miniPCIe card in USB - MiniPCIe reduction

Tested in "Dasaita V600" with "HA3_PX5_10.0_ota(20210225)"

In status bar is LTE and signal bar, in Settings is (in this ROM) not implementet MobileData,

but is posible add MobileData Tile to Notification, after hold on it, is show MobileData information,

data statistic, can be set data limit etc...

Only one step is need to module work, replace default ril library with another one libril-ec20.so (already present in ROM). Also i try with libreference-ril.so from (not public avaiable) Quectel_Android_RIL_Driver_V2.8.8_beta.tgz - too work...

Not sure if is possible permanent change (vendor.)rild.libpath variable, then i simply replace file...

# Determinate what library is set
getprop | rild.libpath
[rild.libpath]: [/vendor/lib64/libril-rk29-dataonly.so]
[vendor.rild.libpath]: [/vendor/lib64/libril-rk29-dataonly.so]

# remount /vendor as read-write:

ln libril-ec20.so -s /vendor/lib64/libril-rk29-dataonly.so

# not know if need, but for sure also:
mv /vendor/lib/libril-rk29-dataonly.so /vendor/lib/libril-rk29-dataonly.so.orig
ln libril-ec20.so -s /vendor/lib/libril-rk29-dataonly.so

[MTCD Android Head Units General] Marko.Zuzic:
Hi everyone.

This was nice thread which worked for me. But I have one problem which I am not sure if it is ZTE MF833V 4G dongle issue or my RK3399 PX6 issue.

Now, after some testing and investigation, I have come to this conclusion.

I have modified my dongle as from this post trough Putty and COM port etc. Works fine.

Now, the issue is following. Once I turn on the car/radio. Radio boots up (in the meantime, dongle is fully booted and working) and boom, I have instant 4G. Now if I start driving, I lose the 4G but still get the GSM.

I have downloaded some App which pings on each new Cell tower, and noticed that on each new Cell tower, tower is recognized but I lose the 4G connection while GSM stays online.

I have re-done that few times. I am sure that this is not USB power issue since on the place, 4G is stable and dongle works for half an hour (may time I was testing) and at very presence of new cell tower connection, 4G is lost, GSM is up.

Any idea on this?

I have:

Rockchip

rk3399

rk30board

Android 9 (fake 10)

4.4.167+ #2067 SMP PREEMPT

Audio : rt5651

Wi-Fi AP6210

Sound: realtekrt5651co

Should I flash with Malasyk ROM, which ROM would be applicable for this model?

Additional issue not connected with 4G is that in the EQ settings, EQ presents have way better sound than Custom EQ with the same EQ settings. Any idea on that? (Not so important since I decided to use Rock present)
[MTCD Android Head Units General] Marko.Zuzic:
Hi all again. I have identified the issue. ZTE MF833V 4G usb dongle is not MultiBand therefore, it is not meant to be used on road when driving since it can not change data connection due to change of frequency on each new cell tower.

I was unable to find any MultiBand 4G dongle so I came up with folowing solution.

I have took my old Iphone 4 which was in drawer, flashed the iOS, inserted SIM card, connected it to the usb of a car (for power supply purpose) enabled hotspot on the iPhone, connected the radio to the wifi hotspot, and know, on each start of the radio, radio automaticly connects to the hotspot and there is internet connection. Iphone 4 is 3G device and does not support 4G, but for the youtube music, radio app it is quite fast and stable still.

So, if anybody have similar situation, just use your old iphone or newer device which supports 4g and use it like I did.

[MTCD Android Head Units General] Cutprods:
Just like to say, I've had a generic Xtrons 4/32 PX5/Oreo 8, GS manufactured, OEM 'Lookalike' HU, bog non-rooted, stock rom/MCU (Updated only once I think - never touched custom roms) in my Audi A4 for over 5 years now. It has been absolutely reliable, except once, when it crashed - I took it out, took it apart and reseated all connections and it was 100% fine again, that was 2 years ago. It was plug and play from day one; including steering wheel controls; the audio has been stellar, as good as the Audi Symphony it replaced - no hum no interference; BT/Wifi/GPS has never been a problem either. The radio is crap, but that is down to the complex diversity ariel then used by VW (modulation data was fed back to the ariel amp from the original HU in a two way process, hence two Fakras), for which no aftermarket has a satisfactory solution -Navradio+ makes it bearable. The only extra mods have been MTCDTools/MTCDialer, to get Mic button on the steering wheel working for GA voice commands/Phone. Oh, I added a good mic, Fisicon or something I think it was, instead of the rubbish one that came with it, in the OEM place, where the original BT one was, calls have always been very clear too. At the time this HU was considerably cheaper than the branded solutions, with much more features - they've had to up their game because of the Chinese.

What are rubbish, it is true, are just about all the dongles and accessories for these Chinese HUs and that includes, 3/4G, Dab+ and stick on ariels (I have had two, they just die), AA/Carplay dongles, TMPS, OBD2 (I use OBDEleven) and reversing camera/sensors etc. The only accessory that has been equally reliable is the DVR front camera; but then it's inside all the time.

I now use Android Auto with it, using Headunit Reloaded and a Motorala MA1 dongle for 100% reliable, automatic wireless connection. But I still have it all on the Xtrons for emergencies, or if I forget my phone on short journeys; Sygic premium, up to date maps; Spotify/Power amp etc; Agama Launcher. But honestly for me AA does everything I want in the best and safest way possible.

So I personally can't agree with you, a least in my case.

I do not know how it is possible if there is no connection to a wifi network.

Can anyone help me?!

Even though few apps has internet connecting, i dont see any symbol of LTE signal for USBto ether. Pls suggest what is wrong.

Also, it take long time (~60secs) to come-up. i think first dongle boot in SD mode then switch to modem mode. is there to boot directly to modem mode. No need of SD card mode.
[MTCD Android Head Units General] PekeMM:
For me I needed to put Stick in Modem Only Mode using Terminal AT commands.

These worked for me:

My setting enable only modem: AT^U2DIAG=0

To enable modem and SD card reader (no CD-ROM): AT^U2DIAG=256

Enable modem and CD-ROM (no SD card reader): AT^U2DIAG=1

Enable everything: AT^U2DIAG=255

You can test this on PC as when you connect USB it doesn't add drive letter to My Computer.

EDIT Note: CD-ROM Drivers are very outdated so there is no use for enabling that at all.

MANY USB-STICKS WORKS AS ethernet-simulated device. BUT: we only searching for REAL MODEMS (pls. see post #1). a wifi or ethernet-simulated connection is NOT RECONIZED AS A MOBILE CONNECTON. the problem is, android make a lot of traffic with wifi/simulated-ethernet connections.

so the E3372 ist not what we are looking for, sorry.

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] snakedoc73:
you have to read the specs of handling data-connections in android systems....

shortly:

all apps, producing high data throughput, (like cloud-apps, whatsapp, telegram, video-chat, streamon, and,and,and...) only differs between mobil-connections (2g/3g/4g) and home-connections (wifi, ethernet, internet over bt, ...), BECAUSE when a real mobil-connection is deteced the apps step down data-throughput or full stop data-traffic (like cloud-aps, video-downloads on whatsapp,...). if your mobil-connection is emulated via ethernet, android/apps will not reconize this and use full data throughput and your data-limit reached quickly. :D
