Alrighty,
So I keep trying to update my g2x through LG but I continuously get an error message that says, "Problem with communication between cell phone and PC", and then it never goes past 4%. Yes, I've downloaded the proper drivers, and have followed the prompts of disconnecting the phone, removing the battery, powering back and pressing restart (countless times). None of it works though. And no, my phone isn't bricking up on the SW update, so that thread doesn't really help me.
I've been doing some research and it seems that it just doesn't work for some phones, but I'm wondering if anyone here has been able to successfully troubleshoot this.
Yeah, I'm one of the unfortunate ones that got a bad phone a while ago, so I'm hoping I can find a way to make it work...
Thanks in advance!!
I have had the same problem. I have a G2x that I got off ebay. It was un-moded, running stock Froyo 2.2.2. I went to the T-Mobile / LG update site and followed the steps. The program actually worked the first time, it went through the whole update procedure and said it was complete. The phone restarted, but when it restarted it no longer recognizes the SIM card and there is a question mark for the battery symbol. When I go into the settings, it does not show a baseband version. I have tried to re-install using the update program, but it stops after 36% saying "Problem with communication between cell phone and PC". Any ideas?

Mine did this the first time. This is where the phone is never commanded to boot into S/W update mode so at least this is not a step where it can be bricked, as no update has actually occurred yet.
This is how I fixed it and got mine to update. Use a different USB port on your computer. Yes there are different as some are on internal hubs. The update must have a direct USB port with no hubs in between. I also reinstalled the drivers through the LG Update program and not from the LG website. When I did this and plugged in my phone about eight new devices were detected and installed as opposed to about two the first time around. Also, make sure your phone is in debug mode in Android application settings.
Then make sure you disable any anti-virus programs and turn off the Windows firewall. Then use ctrl-alt-delete and close down any programs running. Also go to the taskbar and click on the up arror (if Windows 7) and right click on each icon and see if you can close it down. Also, unplug all other USB devices (even a mouse if you don't need it) as they can interfere with communications between the updater program and your phone. The only USB device I left connected to my computer was the keyboard.
The LG Updater must be run in Admin mode. If when you run it you get a Windows warning asking you if it is ok for this program to make changes to your computer then it is launching in Admin mode. If not right click the LG Updater icon by clicking Start>All Program>LGMobile Support Tool>LGMobile update. Right click the last item and run it in admin mode. Again this is assuming you are running Windows 7. Admin mode is not necessary for Windows XP.
If all the drivers get loaded properly and you are not on a flakey USB port then at 4% the updater instructs the phone to reboot into S/W Update mode and that is where the real magic happens if you are lucky.

Use another USB port and try again. At various points in the update the updater resets the phones usb port and it has to reconnect. If it doesn't connect don't do a battery pull. Just try removing the USB cable and reinserting it. If you hear the computer beep wait a bit and then click restart on the updater. Hopefully it should see the device this time and continue the update.
Hey gang - I've been traveling for work and just have some crappy slow satellite wifi for access. The phone has been great because I can use wifi calling and all is good.
A few weeks ago my phone crashed. When I rebooted I was at the "touch android to begin" screen. Well... fix permissions and clear caches didn't work.
So next I restored a backup from CWM.
Unfortunately, after that the phone hangs at the initial Samsung splash screen.
Now, stupid me didn't go an a six-month trip with the Android software on my laptop - so I had to wait for my wife to mail me a thumbdrive that has SOC, HOC, drivers, & etc. on it in order to do anything.
In a previous thread from when this first happened, you all recommended I use HOC to flash the phone back to stock. Which now that (yesterday) I got the thumbdrive in the mail, I am happy to do.
My problem comes from the fact that the phone hangs at the Samsung splash screen seemingly no matter what I do... zadig.exe doesn't recognize the phone on the USB port (just "unknown device") and therefore HOC can't do anything (I think?) Furthermore, I can't even get back into recovery or download mode; at least not with the several techniques I've tried so far.
Recommendations? Or am I hosed?
Thanks in advance,

Interesting problem. I have bricked my phone a bunch of times and have always been able to get back to at least "download Mode". The method I use to go to "Download Mode" is With the usb cable plugged into the computer only, power off the phone. If phone wont power off, or stay powered off, pull battery, then put battery back in. Now hold vol down and vol up buttons only, keep holding these buttons as you plug the usb cable into the phone. In 3 seconds the download screen should appear. I hope this helps you get your phone back.

This sounds like a time where a jig would be helpful. Any chance you can have your wife order one, and send to you? http://www.youtube.com/watch?v=D7I4dFX_iJ4
This should put you straight into download mode, and you can then flash.
Thanks, guys. I continued fiddling and got the phone into DL mode.
I also noted that when plugging and unplugging the phone, it would show up in zadig as "unknown device."
I tried to load the drivers on that, but (a) it still shows up as "unknown device" and (b) when I run HOC it doesn't see the phone under the list of compatible devices.
So.... still kind of stuck.
Any more ideas?
Oop. duplicate post
It's been awhile since I've played with the one clicks, but, "serial gadget" is what I remember seeing when I used them.
Right. MORE messing around later and "Serial Gadget" is it.
That said, I still think I have a driver issue. I have tried uninstalling and reinstalling the zadig-recommended drivers for Serial Gadget several times. I also tried manually installing the drivers from Super One Click.
Anyway, now when I load up HOC I get the green <<connected>> at bottom; but then sometimes it wants me to install the drivers (again) and sometimes it gets past that part, but then goes to
Flashing Kernel: 0%
...hangs there for about 10 seconds and then
Failed!
So... driver thing you think?
Thanks again,
If you reboot the phone after the 0% hanging for 10 seconds, does it go to the yellow exclamation mark screen? If so, just reflash again and you should be back to working... both my and my wife's phone always did that when I had to flash a kernel.
That's just another download screen that theraze is describing.
Exacatly. But the alternate download screen always came up after restarting the phone after a 'failed' flash where it stayed at 0% where it was successfully communicating through the cable. That just meant to not break the drivers or unplug anything... just reboot fast and finish up quickly.
Okay - I can definitely try that! It had not occurred to me to try and reboot the phone right then.
Question, though - when I get the "Failed!" Then HOC essentially hangs, when it says something along the lines of "ending session..." and never progresses from there. So how do you "restart quickly?" Because I have to like, close and reopen HOC. I guess I will see if it succeeds at ending the session when I reboot.
I will try it again. Strange though, sometimes HOC accepts the existing driver (I managed to DL the Samsung driver installer) and sometimes it wants to reinstall "WinUSB." does that make sense? Is the WinUSB an acceptable one?
The winusb is the right driver for heimdall, it doesn't like the Samsung driver.

Samsung drivers and the one click drivers clash. Yes, uninstall Samsung completely if you want to use the one click.
Hm. Thanks for that - might be part of the problem.
Dunno what I did differently, if anything, but last night I tried flashing again and this time it went through! I was very glad to see the whole HOC process completed successfully!
So anyway - thanks so much for the help, guys.
My granddaughter recently received the iRola DX752, and yesterday when she tried to turn it on it came up with "No Command" on the screen. She cannot access the main menu. What can I do?
Use the volume up down buttons to access the menu, select reboot device now, let it reboot and it should be good. Somehow she activated the emergency recovery system for the device, that's the screen your seeing with the Android on its back and "no command" under it.

Hello, I've got the same tablet with the same problem. Rebooting, wipe data and wipe cache all don't work, just keeps coming up to the same no command screen. Any idea how to restore it?
Thanks,
Mike
What happened before this? How did you get to this error? Did you press something in recovery mode, or did you just turn it on one day, and it gave the error?
As far as I know my son either shut it off or, more likely, played on it until the battery died. I tried finding the Kocaso firmware to flash onto it, but I can't find the serial number on the model list. I even took the back cover off hoping to find some better identification there, but none of the codes helped unfortunately.
Is there not a default for that model of phone? Some manufacturers have one or two files for all of a range of phones. Also, is it recognised by ADB? (Or does a computer not recognise it at all?)

Anyone having issues with AFT and the GS7? When I plug in the GS7, AFT launches but I get an error that the device is locked, even though it isn't (screen is on and it's unlocked). I've tried removing security just to eliminate that, doesn't help.
Other Android 6.0 devices work fine with AFT so it's clearly GS7 related.
Particularly annoying because you can't yet write directly to the External SD card

When you connect S7 to the MAC, it says cannot connected, but a popup appears on your phone. Allow it, and don't disconnect the USB cabel. Once again, start Android File Transfer App. This is how it works. Each time when you plug S7 in, you have to allow the connection on the phone, after that it works until you disconnect S7.
When I plug mine in and change the setting to media transfer on the phone AFT pops up and says "try reconnecting or restarting your device" then closes. Every time

Please don't assume we're rookies. It does not work. Even after clicking "allow" for permissions, it fails every time.
Also don't assume every variant is the same.
For anyone who seems to be hitting a dead end, this completely solved my problem...

You mean after allowing and not pulling USB cable out? After allowing just open Android File Transfer app again. DO NOT REMOVE the cable!

Your solution didn't work for me, I still have to allow access for the computer each time I connect the S7. After allowing it works flawlessly.

Yes, that's true. I couldn't get it to connect no matter what, without uninstalling Kies. That was my OP.

OK, I found a real solution: install Samsung Smart Switch and update it. When phone is connected (don't have to allow) there is a small arrow on the right side of the name of your device, expand it, and a small folder icon opens a file manager like AFT. By the way it has also a backup/restore/update/syncMAC function without root.
If you have been getting a response when plugging in a Galaxy S7 or Galaxy S7 edge, do the following:
Go the the Kies website and download Kies for Mac.
Next, openKiesMacSetup.dmg which you've just downloaded.
Click Uninstall. Your Mac will ask you to open the app, so you'll need to open it.
Once it's done uninstalling Kies you probably had on your computer from a while back and no longer use, once you plug in your new GS7 or GS7 edge, and open the AFT application on your Mac, it should still give you a weird response, but on your phone, this time it'll ask you if you're ready to connect your phone and open it up to see files on your computer. Select that you do, and it'll work.
A Finder window opens, and the model number will appear in the center of the Finder window with the requisite files.
Actually, unless I missed it, nobody touched on the solution, which is incredibly simple. I found it on accident. The default setting for the GS7 is to CHARGE when plugged into a Mac (maybe PC too?). Swipe the top notification area, tap "charging" and switch it to file transfer, or photo, or whatever else you want. Good luck!!!
Fixed it for me just now
I was having all of the above issues. What worked for me was completely removing all traces of Android File Transfer (including other mobile sync applications) with AppDelete. Then I reinstalled Android file transfer, plugged my phone in, tapped "Allow", and it worked!

I struggled with this, as well. I even uninstalled all KIES drivers form my Mac and AFT still didn't work with my S7 until I did the following:
(1) Plug the S7 USB into the Mac.
(2) Down swipe the status bar at the top and you should see a "USB Charging" status.
(3) Tap on the "USB Charging" status and a menu with radio buttons should pop up.
(4) Choose the "File Transfer" option.
After doing that, AFT worked properly and it didn't even require me to click "Allow" or anything else. It just worked.
mickliq's solution worked for me as well (hadn't been able to connect an s7 or s6 to a mac air osx 10.11.4 until downloading and uninstalling Kies). Thanks!

I succeed to solve it by removing SideSync on Mac
I had the same problem and discover that it was SideSync that make Android File Transfer not working.
I remove SideSync on my Mac and then it works !
So, something very weird started happening to my phone. Out of nowhere, about 7 hours ago, it would stop charging whenever it was on, charging only when it was off and connected to my laptop. However, I thought it was just something wrong in the dev options, and I went to change whatever was the USB option to "charge phone". With this, I did accidentally forgot to activate the OEM option, and had to reboot not long after. You can probably see where this is going now.
Now I have a phone that bootloops on the FAP Lock message, and whenever I go to download mode to fix it, my PC just doesn't recognize the Phone. I've tried different USB cables, all of them are only recognized when the phone is shut down. So it isn't a hardware problem, because the Phone actually charges when it's shut down, and it isn't a problem with my USB ports or cables, as anything else I use with it works fine. And the worst part is, I need this phone today for a serious bank matter, and I can't afford to lose any data on it either, there's some very personal important stuff from yesterday that wasn't backed up yet. And keep in mind that paying for it to be fixed is the last option for me, as I can't afford it (besides, I fear they might end up getting the phone in factory reset mode, and I can't lose that data as I said).
Any kind of suggestions on how to get either the PC to recognize the phone, or flashing in a different way that doesn't need the PC to recognize the device? Thanks in advance.
Edit: Whenever I try to connect the phone via USB, it doesn't even make the Windows "USB connected" sound, it's just like it isn't there at all. One time, I got it to show, but it was as a "unrecognized usb device", and I haven't been able to replicate it yet.
