Can you transfer a file from computer to phone using USB-C cable? Do you have fast charge when connect the phone to charger?
If the answer is yes, you have a problem with pen-drive (must be formatted NTFS) or USB-C OTG adaptor.

I did format my pen drive to FAT32 like huawei told to do in their website oO, but my samsung phones can see the otg and the flash drive. I did try 3 flash drives and 2 OTG
I dont know if is really a fast charger 40W , how I can distinguish?
Yes I did connect OTG - > UBS UBS to my Pc, and it opens the huawei software

First activate from battery menu. Then avoid to use the case. And put your watch on the back of the phone (near camera). Move it slowly on the back.

Maybe your (other) device is not compatible with this kind of charging, and it uses just its charger (wireless).

See my P40 Pro + GT 2 Pro. It is not so cool. I don't use this.
Your browser is not able to display this video.

soo I did my tests now. 2 usb pens formated with NTFS....still nothing. Test 2 pens in 2 OTGs and still nothing.
Both my samsung still recognizes the otgs ans pen drives
And yes, usbc to pc I can do file transfer.​witch otg is compatible....
Any way I think I will recall huawei service

@badmania98 anyway to roolback to instal gsm without otg? maybe it fixes otg

There are perfectly good reason for the designers to come out with various socket designs other than the size issue, i.e. avoid users from pluging in things that aren't compatible. E.g., I can make you a USB-to-240V-3-pin-plug converter, you just dont plug that in.
If there were to be the slightest possible chance that it will work, there would be a forest of such 'converter available'.
And, among all the above stuff I said, do a search before you (soterisk) post multiple thread across all the forum. It save you times and avoid frustration from others as well. This topic has been discussed a gazillion times, together with other topic such as, "I have a USB converter, I think I can plugin my ext-HDD/mouse/keyboard into my Wizard".

I guaran-f-n-tee that this will NOT work. You could possibly destroy your wizard though. So go ahead without reading anything about this before hand and watch your wizard burn.
There is no hardware support for one(ie. video card out support) and 2 there is no software support for vid out. You cannot make something that is not there work. Good luck.
P.S. There is built in laser beam hardware support on the wizard. Also the Petrol free transporter is working although it is a little buggy.
nope. no way.
even if there were drivers - the wizard has no usb host capabilities so this just won't work.
Actually, the HTC Advantage (Athena) supports this feature:
"HTC proprietary 16-pin combined port (USB 1.1 host/VGA and TV Out)"
(source: http://www.htc.com/product/03-product_x7501.htm)
Don't whether it is a separate port as there is another port mentioned as well:
"HTC ExtUSB™(11-pin mini-USB and audio jack in one)"
(source: as above)
I would reckon it would be less risky if you just get the cable from it and try to connect to a Wizard (still at your own risk) ...
Personally, I would also strongly doubt it (due to the technical issues as mentioned above)
Cheers!

It's ok. Some people just talk nonsense, thats why you get all sorts of silly emails forwarded to your inbox. Anyway, AFAIK, there are some phones (HTC if I remember correctly) that supports video/VGA out. Probably that's what the people are talking about.

How to manual update a complete stock US wifi only Xoom to 3.1 without host cable?

My xoom is NOT rooted and I do not intend to root it. I just want to manual update it because the update still haven't showed up on the device
Thx.
Sorry, nope. I'm in the same boat with an unactivated 3g.

several how-to guides available. You must have a USB micro-USB female OTG adapter and a thumb drive. If you don't, go get one then read these forums again.

Yes, the problem is that i don´t have one right now and can´t get one shipped quickly. I live in Brazil and bought one on ebay last week. It´s coming from Hong Kong lol
But i have read on the forum that the recovery option trough USB is avaible ONLY to 3G models and that´s not my case. Is that true?
Thx.
Tried OTG Cable - No Luck
I tried the procedure outlined in the forums. I've made my own OTG cable by connecting a gender USB Female-to-Female adapter. Tried formatting my San Disk Cruzer or even micro-SD to USB converter and following the procedure. I get E: Cannot locate /sdcard (No such file or directory) I have the update.zip file in the root of either the thumbdrive or microSD card plugged into the microSD to USB converter. I saw someone make their own cable and provide a photo and I pretty much did the same thing. Any ideas?

Someone should correct me if I'm wrong, but an OTG cable is different from a converter. OTG is a specification that requires a very small chip in the cable. All you made with a F-F adapter is a USBmicro to USB converter. But the idea was good
Anyone know if the OTG is built into the USB cable that came with the xoom? Is it built into any cable? I can get a F-F adapter tomorrow and give this a try, but if someone says that it's never in the cables then I won't bother.
host cable doest need any chip.
I bought a standard USB adapter and connected pin 4 to pin 5 on the micro USB plug side, worked great.

Yes, i did solder the wire. I removed the plastic cover with a knife and soldered the wire to the pins 4 and 5.
I must say I'm not good at soldering, but it worked, so i believe anyone can do it. Just check with a multimeter that there is no short with other pins before you use your creation.

Dex Unexpectedly Works Using USB-C hub

THE GOOD:
I bought a USB-C hub (TOPGEEK USB C to HDMI 3-in-1 Digital Multiport Adapter on Amazon for $21.99, can't post the link on here) for my Chromebook Pro and it works great mirroring and extending the desktop on an external monitor. I figured I'd give it a shot on my unlocked S8+, and low and behold, it launched Dex from my phone without help from any 3rd party app, rooting the device, etc.!
THE BAD:
I can run Dex and have connected a USB keyboard/mouse combo, but this setup only works using the phone battery. As soon as I plug in the Samsung charger, it kills Dex and exits the app. I tried skipping the HDMI cord and just tried charging the S8, but that does not work either -- BUT, it will charge the chromebook. So I am confused as ever, and everything I've read on XDA, googled, YouTubed, etc. does not match exactly what I'm using or have setup, so it's hard to draw any conclusions.
Any thoughts of what could be going on? I'm tempted to buy another hub, but I don't know what to look for that would fix my problem.

Anyone have a suggestion of what to try next? I thought there'd be more excitement since I am not rooted, did not flash a custom kernel, etc. Just plugged in the USB-C hub and launched Dex directly.
Or am I missing something??? Nothing I've read exactly matches the case I've got right now...

It certainly is curious, but it still is Dex. - totally not interesting for 99% of the S8(+) Users. Plus it´s already achievable through custom Kernels.

For using Dex and charging simultaneously you can use the wireless charger free given by Samsung. Let me know if that works
Wireless charger offer still active?
Can anyone confirm for me whether Samsung is still offering the free wireless charger for new S8/S8+ owners? I have a new AT&T Galaxy S8+ and it does not have the "My Galaxy" app loaded on it. I also can't find it in either the Play Store or the Galaxy Apps store. Does anyone know if this offer is still being honored? I see a page about it on the Samsung website, but all the instructions talk about using the "My Galaxy" app to get the coupon code to claim one.
Thanks!

Apple CarPlay Dongle - Autoplay - Not working correctly

Hello all!
I have bought the Apple Carplay Dongle with the app called AutoPlay. (https://www.amazon.de/gp/product/B076D2BP4S) The App and the dongle have the newest version.
The problem is that the head unit will start completely new or the connection get lost to the device. I tried several devices (iPhone 5S, iPhone 6S Plus, iPhone 7 Plus, iPhone X) - I also changed the lightning cable.
The usb from my device is working. Maybe I do something wrong?
I used a XTRONS, Android 8, Octa-Core, 4GB RAM, 32GB ROM device.
Some suggestions would be great.

The original adaptor appears to be made by Carlinke. They have a website of the same name - you should start there (sorry, I can't post external links yet).
I had to buy a USB splitter to get my CarPlay dongle to work reliably. A single USB port just wasn’t enough.
Now in the cold time of the year I have a problem with the dongle. The dongle is not connect over the usb to the android device. The app says that I have to connect the box. Is this normal? - After some time of driving it is working.
Now it is the problem that I have to restart my device to get the box recognized by the app. Did someone have some suggestions?

looks like you have the carlinkit dongle like mine, you may need to update firmware on box. I got the latest box firmware from alliexpress selleer ( as per time of this post )
install instuctions
1) format a USB drive as FAT32
2) place img file in root of USB
3) plug dongle into andorid unit ( do not put in USB yet )
4) open app
5) once app asks you to connect phone, plug in USB drive into dongle.
6) you will get message on app saying box updating.
7 ) finally check setting menu in APP to see box and software up to date ( you will need to be connected to WIFI for this I belive)
Thanks for your post.
Is it right that the latest version of app and dongle is from the end of december 2018?
I have the same box on a px5 android 6 and it keeps restarting/disconnecting when I use a navigation app like google maps. I tried using 2 usb ports for extra charge, different phone, cable, etc.
nothing works
Yes, for me it is the same.
I think there is also no update available since 4 months. I do not know why.

Carplay - Phone that supports charging and OTG simultaneously?

Hi all,
I'm looking for the phone that allows charging and using OTG simultaneously. I have the Carplay adapter that can be connected to the android phone and I want to use it in my motorcycle as media dashboard. The problem I'm facing right now is that every phone I'm using doesn't support the charging. When I connect the power supply the communication with accessory stops and when it's disconnected the accessory is working again.
I was testing on Motorola G31, Samsung S10 and Pixel 2 XL. The adapter itself works fine as I was testing it on my Macbook and I can charge and use usb accessory at the same time.
If you know some phone that will work I would be greatfull for the recommendation. I prefer the usbc connection.
The second question I have which is way less important. Is there an custom rom that is very lightweight and allow just to run the application for the adapter to boot as fast as possible?
=====================================================
For anyone looking for simple answer I can confirm that Poco X3 is working fine, if you know other phones please add a post

Say what??? You're killing me.
Yes, of course there is OTG over USB 3 Type C.
You buy a (passive) adapter and it works, just like with micro USB 2.
Now you're going to ask me how.
I actually have a device that I build that switches dynamically straight USB vs OTG.
It's a 5.1k resistor from a CC to ground puts it in OTG.
Here's a video of two Androids hooked together with one being a "digitizer" and the other using it through a OTG adapter.
See: https://www.amazon.com/24pin-USB-C-Resistor-Black-Housing/dp/B07T97LC9L
I've found the youtube channel that shows that it's possible using Poco X3.
Here's an adapter I made for Type C. You can use it normally (with a straight micro USB cable) or as OTG with a micro USB OTG adapter.
And if you connect it to a 5 wire device that switches the micro USB ID, then it can do both alternately.
The black heat shrink hides a 5.1k resistor.
Oh, as far as PD goes:
Code:
# USB power role changes
on property:sys.usb.typec.power_role=source
write /sys/class/dual_role_usb/otg_default/power_role ${sys.usb.typec.power_role}
on property:sys.usb.typec.power_role=sink

you should maybe read about USB-C and its protocols especially USB-PD.
oh I have one too, and it works. with custom kernel you can even charge on host mode.

USB-C devices don't use USB On-The-GO (OTG) like the older devices discussed here, instead they use something called Dual-Role-Mode/Dual-Role-Devices (DRD).
Whereas USB-OTG host/client was determined by hardware; DRD uses context to determine the host/client devices, which needs to be implemented in firmware/software/logic.

Uh, what?
I'm fully aware of how USB-C signalling works, thanks.
The link you pointed me to confirms exactly what I said:
All existing OTG methodologies (ID pin, Host Negotiation Protocol, and Session Request Protocol) are prohibited from being used on USB Type-C ports!

@smnc if I would reply to you I would have mentioned you. I just quoted your post from another thread.
Maybe you don't know this, but if you quote someone, it actually does tag them, exactly like a reply.
If you don't want to drag someone into a conversation you can just copy/paste the text and then manually apply the quote formatting.
Have a good evening.
Yawn.
Of course there is no "OTG" in Type C.
But if somebody wants to use a regular USB A plug of a keyboard/mouse on their Type C device they just buy an "OTG adapter".
USB Type-C plugs associated with the “A” end of a legacy adapter cable are required to have Rd (5.1 kΩ ± 20%) termination incorporated into the plug assembly – see Section 4.5.3.2.1.

I don't think it's polite to quote people without giving a citation.
