Help LG & ADB

I think this thread will be a ghost town, but:

Through about six previous droids, I've using Klink tether to have an alternative online method. Then I got an LG Fuel and neither ADB or Klink worked. So then I got an LG Access LTE, which I really really like, but it won't Klink either.

I've tried updating the PC drivers, but I'm pretty sure the problem is just the LG phone. Narrowing down to droid solutions, I've googled the play store to no avail. I don't really know much, I just keep reading things and trying things until I strike gold.

USB itself is fine, but is there a trick to LG phones that wake them up to ADB?
 
<fireproofoveralls=ON>
USB debugging is enabled, yes? Apologies for asking, but I've inadvertently disabled it myself then wondered why stuff that worked fine previously didn't.
 
LG United Driver + usb degugging on should work for any LG, assuming Windows. Which one of those driver zips that you linked are you using? There may be a newer one available on the official LG site, not sure.

What error are you getting from adb? Device not found, or other?
 
Yes to both above, several times, no luck. I used LG United Mobile Driver and also tried its neighbor, LG VZW United WHQL. The former installs fine, I reboot the PC and it loads the drivers. The latter doesn't even appear as a file, but fergit that. I turn on bugging and the droid confirms that connection. Then I start Klink on the droid and it seems happy, but when I start it on the PC, that doesn't see the droid at all. I've also tried about every option in the droid's Klink settings, for lack of anything better to do. Over time, I had already developed a friendly relation with Kevin Ko, Klink's developer. I've asked him about this one several times, he has offered suggestions, nothing works. I haven't pestered him some time, but it still comes back to bother me -- I'll probably email him a link to this thread.
 
I have no knowledge on the Klink app but to rule out an app problem, rather than a generic adb problem, I'd use the sdk or our forum's mini sdk to check for proper adb connection:

ADB Guide (updated 2014/11/11)

If you already have that, forgive my unecessary explanation. ;)
The download for that is at the bottom of Early's post.
  • Unzip that to the root of your PC's "C" drive so you end up with a folder called sdk-tools which has some stuff in it.
  • Plug in the phone with usb debugging enabled
  • Open command prompt and type cd c:\sdk-tools. Then adb devices.
  • Watch your phone's screen at this time. If the screen doesn't come on itself following that last command, turn the screen on yourself. Look for a prompt on the screen (RSA promt). Check the little box to always allow a connection with this PC, then press ok or accept or however it's worded.
If your device is shown (as a string of numbers/letters), then you have a positive adb connection. If in doubt, you can issue an adb reboot command at which time your phone should reboot. If all that works, then its a problem with the Klink app and not an adb issue. Retry the Klink app after that too. The RSA prompt may have been holding it back from working properly.

If all this fails, try different adb drivers in this order:
Koush Universal ADB Driver
PDAnet Drivers

Concerning the PDAnet drivers...you download the program and it comes bundled with generic adb drivers. You don't even have to run the program itself. So with PDAnet on your machine, plug the phone in + usb debugging and then reboot the PC from that state. Basically, you then hope when it boots back up, it will recognize your still plugged in device and auto apply the newly found drivers which you have on your PC now.
 
I think that'll wind up being over my tiny head, but if Kevin Ko doesn't give me something else, I'll try it.
 
I probably got this popup when I first launched debugging, but I can't remember. But even though I should get it back by doing Revoke USB Authorizations, I can't... please don't make me factory reset!

I'd be more apt to clear cache (and possibly data) on the Klink app instead, from your device's application manager. Then restart it and it should start as though it's a new install. Watch your screen as you fire Klink back up and make sure the screen is on at that time. See if you can evoke the RSA prompt that way. Otherwise, you can do it using the instructs I listed earlier using our forum's mini-sdk. It may look daunting, but it really isn't a terribly difficult procedure.
 
Thanks, makes perfect sense, but no go. Out of desperation, I tried foxfi/pdanet for AT&T. It caused the RSA popup to appear but the PC's app went bsod. So rolled back to get it out of my life.
 
Try turning on MTP mode when prompted after plugging in USB, then invoking ADB.

I had to do that on my LG optimus f3 to get ADB working.
 
When I plug USB in, I ain't prompted fer nuthin. And I've had as MTP almost all the time, but the others two don't change anything.
 
This may be a job for Linux.

sudo apt-get install android-tools-adb

Then try with your ADB stuff. Just make sure your adb commands use sudo if they complain about permissions.
 
[SOLVED]

Somewhere in that link, I learned where the RSA key was being stored... c:\Users\(me)\.android\adbkey/

All I had to was delete it, reboot both devices and up popped the RSA prompt on my debugging droid. I gave it permission and now I'm internetting on Klink with the ethernet cable unhooked, like the good old days! But all my gmail logins have failed, later on that.

The craziest part is that I was on the right track all along, running with my eyes shut.

And it appears that, whilst klinking, I only had to log out and in my addresses at the gmail site, then enter the texted verification codes. Now, finally, I can get a Windows laptop for little trips and enjoy a full internet... but is that a good thing?

Having used it for a while, I can say that tethering with a 4G droid is plenty fast, much more usable than 3G.
 
I just added some Mint to my Klink, tastes splendiferous.

And, for my next thread, I bought a forty dollar 7" Apex KK 4.4.2 tablet. It'll never Klink, but will hopefully force me to learn wifi, something I've avoided my whole life. Otherwise it'll be someone else's xmas gift.
 
And now that I've rekindled my tetherabilty, I get this text:

Straight Talk Msg: Your allotted high speed data limit has been reached. Your data speed will be reduced for the remainder of your plan's 30 day cycle. Thank You

The limit is apparently about 3GB. At least they didn't remove one of my fingers.
