Could someone direct me to where the support list is found? The top link doesn't work. Just wondering if there has been any additions.
I'd like to have 4g ideally, is this even possible with these units (I own a huifei)? Can pick up a huawei e3372 for £15 on eBay

Any tried and tested USB wifi dongle as sometimes my units WIFI doesnt turn on, I am hoping I can just add an external USB WIFI dongle to the OTG USB adapter and use that one that way ????

I have a e3372, but I can't make it work..... not an expert either.... but when I plug it in nothing happens. But it works great in my pc
These two work well together on the Head Unit.

You can get other USB broadband modems working if you use the PPP Widget 2 app (https://play.google.com/store/apps/details?id=de.draisberghof.pppwidget2&hl=en). I found it to be pretty annoying though so I came up with an alternative solution.
I now use a TMobile Z915 mobile hotspot. I plan to install a switch to the battery so I can still use it when travelling, but I can otherwise leave it installed in the car and have it powered by the radio. When the car is turned off, it should kill the power to the hotspot. When power is restored it will power up and have instant wifi.
I'm tempted to try my 4G USB broadband modem again just to see if it works now that I've installed the Malaysk ROM. With my portable hotspot, everything is great except that the radio thinks it is always on wifi so it doesn't mind wasting data.
Hello,
I use the Huawei E1750 USB 3G dongle. I see it run not stable and do not know the reason. I usually used this dongle in PC before take it to my car.
Sometime, the HU did not recognizes the dongle, most of times, the problem happens when I start the engine from the HU running by battery's power.
I guess the power supply for the USB port is not enough.
My HU is Klyde MCTB-KLD. RK3066, 800 X 480, Malaysk newest 4.4.4 ROM
Is there someone met this issue before? Please kindly share your experience to help me solve this.
Thanks!

Hi guys,
I am also using a HUAWEI E1750 in my Carjoying HU and had the same problems but maybe I found a solution.
At least the behavior of the dongle improved dramatically.
1. At first I updated the firmware to version 11.126.13.00.00.B418
2. I think this is the important point .... I disabled the CD-ROM and SD-CARD function on the dongle.
You can use for that the DC-Unlocker.
In the white window on the bottom I used this command
AT ^ SETPORT = "A1, A2; 1,2,3,7"

I have a Huawei E160 and unfortunately the AT ^ SETPORT command doesn't work on my dongle. In the past I've tried AT^U2DIAG=0 which stopped it from working with my HU - fixed by reset using AT^U2DIAG=276.
Based on the above advice, I'm now trying AT^U2DIAG=3. It works with the HU but time will tell if it has fixed the reliability issues. I'll update this when I know more.

I tried and successed!
The AT-comand must follow this instruction from http://www.3g-modem-wiki.com/page/Huawei+AT-commands
The code for the "AT^U2DIAG=n" command depends on the model of dongle (Support by/Not support by)
The modem did fix quickly and more stable. But bases on the new firmware update feature: "More saving power" with your suggestion: "Disable CD and SD card reader", I think the main reason is the weak power of USB port. So, increase the USB power is more necessary because we may use any other device on it, not 3G modem only.
Thank you!
It hasn't completely fixed mine, the connection still drops out, but it MIGHT be better than before. Can't be sure though. Based on the above advice about firmware reducing power usage, I'll try that next.
This is for the benefit of anyone who owns a Huawei E160:
Do not install the latest firmware 11.609.10.02.432.b418.
After doing this, it wouldn't work with my HU at all. Unable to add APNs - they're not saved as the dongle is not recognised by the HU. It worked on my PC so wasn't broken, but the HU just didn't like it.
I downgraded to 11.609.06.02.94.B409 (was originally on 11.608.02.02.55 so is still an upgrade) and it now works once more.
I'm going to try out the different AT^U2DIAG commands to see if I can improve reliability.

Hey people,
I have a question. I have a 3g Stick Huawei E1750. It works very good, but I need 4G, because here at the most time only EDGE, and 4G is not supported by the stick. Does anyone knows a compatible working 4g STICK, not a Modem. Thanks

Tried it using an aircard but android only picks up the usb stick.
I dont know if it actually help but I saw this on tech republic when they open the tablet.
3G-ready motherboard and case: Sony left an open spot on the motherboard and inside the case for a 3G or 4G card. The internal mounting bracket even has screw holes for it.
Dont know if it is possible to add an internal modem or install driver for that.

At least worked for me. It disables other functions of USB 3G sticks and leave them to be acting only as 3G modem, which then tablet recognizes.
Is there anything new? I have got rooted ICS on my tablet. Is it possible to use 3G USB Modem on my tablet? I have got 2 USB-Modems. The first is ZTE K3565-Z and the second is Option 4G Systems XS Stick P14. Is there a solution?

If darkjesus's method didn't work, then I'm not sure anything will. These modems are not easy to work on a lighter system like Android.
I'm happy to be proven wrong, of course.
In a german forum, i found an app called "UMTS Manager". With this app you can connect with 3G Networks with some Huawei-Sticks and maybe some other devices, too. They use mode-switch to switch device mode to modem only and then it works for them. Here's the link:
http://www.android-hilfe.de/asus-ee...-stick-zum-laufen-kriegen-17.html#post3236187
Of course, a lot of pages But some of them got ZTE K3565-Z working. For me it doensn't. Maybe we can find a solution
I found the reason, why it does not work on Tablet S. Our Tablet does not create ttyUSB*-devices when attaching 3G Modem to the Tablet. Normally it creates ttyUSB*-devices, attaches the Modem there and you are able to connect. I think it's a kernel issue or Sony modified the kernel. But with Custom Rom and Kernel which has got this "feature" it is possible to connect via 3G Modem. Maybe one of us could create this custom Rom..
So how?

You will have better success looking for a portable 3G-to-WiFi hotspot device. Not only will you not have to worry about installing USB modem drivers, the device will work with a non-rooted tablet. Also, if you have a 3G smart phone, look into WiFi tethering.

Yup, finally I bought portable 3g/4g wireless n router. Easy to use. Thanks by the way.
Hi fellow owners,
I am considering to buy, but I'd prefer to be a cheap and get the 16GB WiFi version. However, it would be nice to be able to use a USB dongle for 3G from time to time. Anybody tried?

good advice. I can certainly do this as well as use a 3g wifi router i have. but using the phone's hot spot drains phone's battery and using a router adds to the bulk. that is why I'd like to try a dongle.

I read in the GSMArena review that the XTZ can be tethered to a phone using Bluetooth:
Even if you get a Tablet Z without 3G, you can still use mobile Internet, provided you have a data plan on your droid phone and the Xperia Link installed. The app simplifies the tethering process. It puts a widget on the homescreen that lets you turn tethering on and off.
You might be thinking that you can just use your droid's Wi-Fi hotspot feature to do the same (and you could). The difference here is that Xperia Link uses Bluetooth to share the Internet connection and not Wi-Fi. This should be more power efficient than a Wi-Fi hotspot especially considering you can keep Bluetooth on all the time, which will let tablet and phone hook up automatically once they are close enough (you can't do that with a hotspot as your battery will be dead in a couple of hours).

I haven't been able to try that yet -- my pre-ordered XTZ has yet to ship -- with my Nexus 4 but it could be a solution to Wifi Hotspot battery drain issue.
-- Edit to add --
Well, found the official Sony Xperia Link in the Google Play Store and it's incompatible with non-Xperia phones apparently. Although, the Bluetooth-tether idea still sounds promising. Is there a way to get around the Sony lock-in?
Works!
So I've got the tablet this week and tried just now to stick the USB modem into it.
Naturally you have to be rooted, then you need a dialer :
PPP Widget
from the author of usb_modeswitch (ubiquitous linux tool to change the usb modems from CD to serial mode)
then you need the usb drivers unsurprisingly missing from the stock rom:
On author's forum
then insmod the modules in the zip file:
cdc-acm.ko
usb_wwan.ko
option.ko
(option requires usb_wwan to be loaded first), drop the widget on the home, it should do its magic and ask you for the APN. Then it works.
what a joy.
p.s. apparently the dongle I have needs more power than there is on the tablet port, so you need a powered hub (clumsy) or an external battery and a Y cable to power it.
Hi,
I'm not able to activate wifi anymore (even after a full Odin restoration) on my SM-T820. So I guess the wifi chipset is dead. Is anyone here has to changed it?

Is Bluetooth working?
This is a 2nd hand tab that I got at low price one because BT wasn't working (wifi was working flawless)
I didn't care because I don't need BT but now, I find out it was the same chipset for both and realize I should have been more careful.

Pretty much out of luck unless your prepared to use a mobile data dongle or a usb ethernet adapter.

Perhaps there are some USB-C wifi dongle somewhere, It's mostly for a home usage. I will check. It would be a good way to extend my tab's life without reducing my wallet's one !

I doubt there's anything specific due to drivers being an issue.
You may get lucky if you find out which chipset the tablet uses then try and find a dongle that has the same chipset.
You would need to connect it via OTG.

Hi there,
At 4pda, they are writing, that some PX5 units have troubles with WiFi/USB below 0°C.
It looks like my Witson unit (MX2 MCU, PX5, Android 8) suffers from exactly this problem. The last days we had warm temperature and USB and WiFi worked perfectly.
Now I went outside and the issues are back. It's 0°C now here!
Can anyone confirm this issue?
At 4PDA, they suggest a fix by adding a screw-whole + screw to better fix the proccessor unit:
https://4pda.ru/forum/index.php?s=&showtopic=883219&view=findpost&p=77467642
It looks like the processor unit is only fixed by 2 and not 3 screws and especially the two most outside pins, which are responsible for wifi and usb suffer from loosing contact with cold temperature.
I'm keen on trying to hardware fix. But I'd like to know if someone has experience with this?
Christian
Seems like a easy issue to check for and then apply if your unit has this issue. You might help others by testing the solution and posting result/images.

I now read the whole post in an ugly into german translated version.
The theory with the processor unit is not confirmed, the people over there discuss about powering issues for the usb ports, temperature-related problems etc. No finally confirmed fix seems availbale yet.
As my unit is less than two weeks old, I am claiming warranty. At least I purchased trough an UK dealer with paypal, so first I hope for a replacement.
If I don't make progress with that, I'll open the unit and look for the issue.
If someone elso would have a confirmed working fix, I'd try it.

There's another thread where a few of us have been researching this problem. The fix is posted HERE. There's no need to open the unit.
There's links in that thread to the 4pda forums where they explain what the issue is also. Long story short, it ends up being a manufacturing defect relating to the USB host controller. Newer versions of the board don't have this problem. But I can confirm the above fix does work like a charm, I've tested it several times.

If anyone is still interested in a hardware fix, my KSP units have a 5-pin IC for USB current limiting and I found if the part is cooled, the USB will not turn on when it wakes up. I replaced one with a TPS2001DDBVT, same package and pinout but better specs. It passed the bench test. I haven't gotten around to installing the HU yet.
Update: I installed the unit with replaced ic, and it behaved differently, though not yet correctly.
It's worth noting, a Dasaita HU which has not exhibited the low-temperature wifi issue has the same USB hub chip, but a different (much larger) crystal attached.
I installed the newer usb hub chip as mentioned in the other thread. No more low temperature problems, however if I reboot the unit via software (with a rooted app), the wifi does not come on. One must reboot with the reset hole. Do not try this while driving.

which upgrade do you suggest? hardware or software?
the problem occurs only with the dab module connected to the cable with 2 usb, while the single USB cable, which I connected the 4G wi-fi router, always works.
If I will installed the hal9k ROM, could I fix the problem?

I'm going for HW repair. I've ordered GL852 sop28 from ALiexp (0,55+3,4USD shipping).
Dasaita knows about problem with GL850, but they proposed to replace chip by myself or to send them SOM board and wait till they resend it back. well, i'm definitelly not happy with their response.
I hope that replacing USB hub will solve at least one other problem - random unmounting usb drives and problems with copying files from usb to sd-card.

and I think that you can check a type of the hub with app USB HUB

Ok. I'm going to check the chip model.
I haven't problems with the Wi-Fi or BT.
when the temperature is low the DAB module connected to the double USB cable doesn't work, everything else are fine.
could I have your same problem?
I changed the gl850 ssop28 with the better version gl852g. Now I have no real problems anymore with my xrc unit. There is a software fix in hal9k 3.1.1 in the mod settings but it was only working when it was not to cold. I had in cold days allway to wait and reboot the system ...

Change the chip is simple?
Which are items do you suggest?
There is a tutorial?
Thanks so much

No, it's not really easy, but without no skills before I did it. I just watch some desoldering and soldering videos and tried a bit with an littel another broken board with a ssop8 socket on it. I desoldered a lot and soldered a lot on it and then I change the chip on my mainboard.

I used a soldering iron beacuse I din't had a hot air station.

Judging from the comments you've bought this right? https://www.aliexpress.com/item/10P...96-43df-b7c8-2d03f857b97b&transAbTest=ae803_5
I might give that a shot.

Yes, I did. It's my picture at the feedbacks.
For me was it a good shot.
Hey guys,
The Mi PAD 4 is the perfect size(in most cases) for a car dash mounting and will be a great replacement for the now very old Nexus 7.
There have been a lot of development over the years of custom ROMs/Kernels that are specifically optimized for such a use scenario.
I for instance am in the process of collecting the needed cable and accessories but since my ROM building knowledge is very limited at best, would be very happy if there are more people here that think this idea is good and somebody builds us the custom ROM/kernel for that.
So lets discuss this.
What we will need are the following main things:
1. Kernel/ROM that is configured for a landscape use.
2. An option to have the device connected to power all the time but not charging (not to kill the battery)
3. An option to turn on the screen automatically on getting power over the USB port and turning of the device after the power is gone (car turned off) (preferably with a delay of some sort)
4. After power is lost to put the tablet in very low power mode by disabling WiFi/LTE/Bluetooth and so on (again configurable) This is to avoid draining the car battery if left for a long time parked.
5. Simultaneous Charging/OTG (this may actually already be possible, but I have still not found an OTG HUB that works properly with the Mi Pad 4)
probably I have forgotten some more things...
Have in mind that all of those I've mentioned above, already have been developed in one form or another for the Nexus 7, so it should be easier than starting from scratch...
Hey,
i am using my MiPad 4 also in my car. So far it is working fine.
I have connected the MiPad via USB to a carhifi DSP (in my case Helix MiniDSP)
Here are my answers to your points:
1. i am using Evie Launcher in landscape mode.
2. see 5.
3. MiPad is waking up and starts to play music as it detects the DSP on the USB-Port when the car is turned on, and is stopping and turning off when the engine is turned off, this is working with the Pad itself and the app Automate
4. use app Automate to turn off all radios when no USB connection is detected
5. i am not sure if this is related to the hardware of the MiPad or the Kernel, i have tested some CustomRoms but was not able to get it working, so i switched back to preinstalled inofficial international MIUI-Rom
Thanks
Hehe i also use it in the Car It was also a Replacement for my old Nexus 7 2013.

Can you please throw some more light on the "preinstalled inofficial international MIUI-Rom" ROM where simultaneous OTG+Charging is working for you? Is this is the fake ROM (as people call it) that vendors install after unlocking the bootloader and then sell it to you?
May be a link to the ROM (if its downloadable) or a screenshot of the ROM information from the tablet, will help.
TIA.

Now that I was able to make OTG+Charging work with HavocOS, am proceeding to replace the Nexus7 in my car with the Pad. Will let you all know how it goes.
I'm also thinking about installing a mi pad 4 into my car. Any news on a good setup and ROM?

HavocOs is working great so far in my car setup.
Which havoc os rom are you using? I flashed the current build today and otg plus charge doesn't work. It's one or the other.
I will next month also run a project for building in my mind in the cars radio mount (2din). So far I found Headunit Reloaded is really cool to have Android car working perfectly! For volume control I use a floating volume button (Virtual Volume Button on Play store).
But the rest I will figure out next month when I get my car finally haha
