[Q] HDMI alternatives - Android Q&A, Help & Troubleshooting

So I am an idiot, I jumped the gun and bought the new Droid Turbo. Thinking it was the latest and greatest etc etc I grabbed it, only to find out later, it does not have HDMI/MHL. It never even crossed my mind, I just assumed HDMI/MHL was standard these days, Every other phone I have had has had it. So my predicament. I use an AppRadio in my car, Cant stand the regular radio and I have been in love with the radio for almost 2 years (i think) but without having HDMI, I can not use the appradio with this new phone. I use the AppRadio Unchained mod that is posted here, or did use it I should say. I think I vaguely remember reading about some people using a cast type device to wirelessly hook up their phone to the radio. My question is, if i use a device like miracast, or what not, will it work like I have installed an HDMI cable, and will I still be able to use the touch functions of the radio, or am I going to need to rethink my purchase and possibly return the phone? Wasn't sure if this was the right place to post this or not. Thanks in advance.

has anybody tried motorola's webtop?

on another phone especially the galaxy sII? wondering it would on another device.
It has a proprietary connector so no.

You have to connect both connectors at the same time. And if I read correctly, one of the two is a proprietary connector by Motorola.
no. i have the atrix. it's just micro hdmi and micro usb. the galaxy has mhl connection which can be used for hdmi out i believe. it's just hard getting mhl because hardly anything is using it right now.
Samsung provides an microUSB to HDMI cable. But then again, you can't connect both at the same time.
And I think the Atrix has some specific drivers (and a lot of modified Android OS files) too. While they can be dumped, you'd need to adapt them on a GSII ROM. And since it's quite useless, nobody will dive into this huge reverse engineering work.
Definately a no-go.
well some of the atrix webtop files have been pulled and that is part of what i was wondering if anybody has tried to do a quick zip with them and seen what happens. i'm pretty sure it isn't that simple because as you've said, probably custom files from motorola. to some peeps it might be worth it to be able to use webttop/lapdock but who knows how deep you gotta dig in. i don't have the skills for it and am not requesting it either. some phones have been able to boot into other os'es and such so this task isn't unsurmountable.
While it isn't surmontable, it would be pretty hard (not only there's some files related to the webtop (libs and such), but there's also a completely changed Android framework). So it would be a pain in the ass to adapt this with Samsung files.
And since there maximum 5 guys in the world who have both a motorola webtop and a Galaxy S II, there's not a lot of chances to have it working.
And again, there are not the right connectors. Even if the software is adapted, there's still the hardware issue.
Well thanks for all the answers. I was more curious about if other android users were curious about webtop and galaxy sii was a good forum to ask because it's a powerful phone and popular. I got the lapdock and it's pretty good for light duty utilization. And easier on the eyes. Thanks for your answers again.
I voided my warranty.

[Q] Htc one x+ root or radio problem....

Hi,
This is my first thread in this forum and My main problem is, I think, my phone. Basically, i have no clue what "root" does to a phone...but that's why I'm here!
To be more precise, i bought a radio (Pioneer AppRadio 2) that apparently it works with many android phone (mine included). The problem is that when i connect it with MHL the radio doesn't recognize it at all...it wont charge, it wont do anything...except the Bluetooth that works even thought I don't connect it...
The thing is, I've red a little bit online, and apparently I need to root the phone....how is that going to change anything? Will it work? How do I "root" the phone?
Thank you for your help!

[Q] question regarding appradio unchained

hello. i'm sorry this question may sound like a total noob question and i am not worthy, but humbly ask for some help.
i currently have a rooted Nexus 5 on stock 4.4.3 and appradio3...trying to get them to mirrorlink with each other via ARUnchained. Based on 3 months of trying to find the correct solution, i'm still not able to make ANY sort of connection between the two. I have the USB extension from the dongle and HDMI cable from the back of AppRadio3 connected to a slimport that I connect to my Nexus 5. I believe I've made the correct connections, but nothing happens on the head unit. It doesn't even try to make a connection....everything is still grayed out (the APP icon and Pandora)
Before, I've tried using the "Start Diagnostic" feature on ARLiberator to which all the marks were green. When I start connection, it immediately disconnects.
I'm starting to believe something is not correct on the hardware part, but I'd really appreciate ANY sort of guidance.
Thanks!

Cast screen to appradio3?

Hi guys if your reading this maybe you can help me. I have an appradio3 that I to be able to cast my screen onto. Now brief background, I used to be on Verizon limited data with a rooted note2 that I direct connected via HDMI. I now have mistakingly switched to att and now i have a new note7 that doesn't have anyway to connect directly to the deck since Samsung has taken it out. Now I've since read about using a Chromecast and casting that way. That's all well and good if and only if you have a Wi-Fi hotspot on your phone which I don't and i dont want to pay for the very limited hotspot plan for my phone to do that. Now I'm not opposed to rooting my note7 which I've looked into that but I've got an sm-n930a. And using the Sprint method doesn't work well for my model. Seen a video were a guy did get his tmoblie phone to root but the process was very lengthy. Or I'm not opposed to rooting if possible the Chromecast. I've got both the newer and the older version of that. I've looking briefly through the Chromecast threads and didn't see if once rooted that you could Wi-Fi direct to the CC. Like once your setting it up it Wi-Fi directs to your phone then switches to normal Wi-Fi. Is this possible??? Or if there's any other device that could get this to work with an appradio3 I'll totally try that.

I'm guessing after the note 7 recall this issue has "solved" its self... I am curious what you did wind up doing. I have the same App radio 3. I used to mirror my S5 to the thing with a samsung hdmi adapter and had full bluetooth touch controlls. Ever since android started setting selinuix to enforced it has become an issue to emulate touch control from the app radio to the phone. Screen mirriroing alone didnt really make me all that happy since I couldnt make it do much without touching the phone. Do you by chance have any advise on this?
What phone did you go to after the Note 7?
Well unfortunately I've gone to an iPhone 7 plus. Which I'm a droid person at heart and it's been a hard switch. Mainly cause I like the ability to mod the droid over iPhone. That said though the iPhone can still hook up to the AppRadio once you've got the appropriate adapters. So right now I can mirror the phone and can watch YouTube videos on the deck. If watching a YouTube it'll allow the phone to go dark or browse for your next video. Still looking into loading videos on the iPhone than watching them on deck but haven't put to much effort into as of yet. The real bummer is that there isn't no support to mod the iPhone to use full touch screen like if you had a droid with the hdmi. I've actually posted on several iPhone forums with just the question and after 2 months have not gotten a response. I still have my note2 and could hook that stuff back up but I have no internet on it so I couldn't watch YouTube from it. And I know this is droid forum but if anybody can help with modding the AppRadio app for iPhone like they did for the droid I'd throw some funds your way, but I can't throw to much since winter time is slow work months for me.

Reverse Tethering on T-820 (Option not available)

I want to be able to plug my new Galaxy Tab S3 (T-820) into my desktop computer or laptop via the USB C cable and not just move files back and forth, (which works fine), but ALSO have access to my desktop's internet connection through USB. I don't want to use WiFi.
I have an Ethernet to USB C dongle, which works fine, but it doesn't allow me to share files or charge my tablet. I'd like to be able to do all three at the same time.
In many of the "How To" articles out there where "Reverse Tethering" is described, they helpfully list the various buttons and widgets to click in order to enable this feature. However the authors always refer to menu items and buttons which don't appear under my tablet's settings. They're not just greyed out. They're simply absent. So that doesn't work.
Neither do any of the various apps on the Google Play Store and elsewhere which promise to provide reverse tethering. They just don't work.
SO...
Being new to the Android (and the smartphone) universe, I did a ton of homework and have so far figured out how to...
Root my tablet. (Done!)
Wade through the swamp of TWRP, ODIN, etc., while tripping spectacularly over the various speed bumps and permission walls provided by the likes of Samsung and Google's paranoid anti-theft (and it would seem from my use case, their anti-happiness) feature set.
Successfully install different flavors of Android.
Install both Magisk and Xposed and try their tethering unlockers with negative results.
After a week of little sleep, I've managed to get through all of this torturous nonsense and amaze myself by not having bricked or totally spoiled my tablet. It still functions! After all the warranty-voiding BS I've crammed through it, I'm feeling quite lucky.
However... I still don't have the ability to tether/reverse tether!
I've learned a lot, but I still feel mostly like a dazed and confused script kiddie (remember when 'script kiddie' was a term? Well for me, it still applies nicely.) I'm trying my level best, but various elements of this whole exercise remain opaque. This is my first post in any forum asking for advice because I finally hit the outer bounds of my DIY energies and pride.
So, if you will indulge my humble request, what I want to know is...
1. Is my tablet even capable on a hardware level of performing a reverse tether, or has the manufacturer locked that feature out so that even a ROM which promises to turn it on will fail to do so?
AND...
2. If it IS possible for a ROM to turn on the tether/reverse tether feature, which one is it and where can I find it?
2a. If there is another solution.., what is it?
I'm currently on...
Android Version 8.0.0
Samsung Experience version 9.0
Kernel Version 3.18.71-13482624
Build Number R16NW.T820XXU1BRE2
I bought this unit off Amazon; it was a refurb and I didn't get it through some cellular provider nor do I have a phone plan. I don't know where this tablet originally came from, but it was all new, sealed and shiny in the box when I got it.
Thanks!
I can appreciate losing a week of sleep. But I don't understand why you need to reverse tether. Enable WiFi and there you go. I think the last time I needed to tether a device through my laptop's internet connection would have been the 1990s.
FWIW the USB-C connector on the TAB S3 is different because if you want to drive an HDMI monitor you need a DisplayLink chip enabled dongle and DisplayLink Presenter app running on the Tab S3. Whereas on my TAB S4 I can just plug any regular old USB-C -> HDMI dongle and display on the monitor. So odds are trying to get reverse tethering working on the Tab S3 is going to be an exercise in futility.

What...? It worked?! Thank-you!
It's hard to believe how much effort and research I'd put into this, how many promising fixes I tried and which failed. In truth I'd given up weeks ago and found myself scornfully looking at the expensive tablet by my desk, wondering if I should hang on to it for its limited uses or sell it on eBay.
Thanks for posting! I can now do what I wanted with this machine.
For others, just follow the directions on the github link provided in the previous post.
I just scrolling around to find fixes for wifi issue - it connect & reconnect every times when on my office connection. Since me unable to use wifi, i try to find the work around using LAN connection. Then i found that.
Happy i can help others. Cheers mate.
