I already have another thread I posted in "All apps & games" I put there by accident I tried to delete, but couldn't figure out how. Anyways, I got a LG Lucid 2 VS870, and I rooted it and uninstalled some system apps. I started it up about a day after I uninstalled the stuff, and it is stuck in a boot loop saying "LG. Security Error." Says security error under LG on the screen. Some were google apps, and I read on a forum elsewhere that I should leave the google apps alone on these phones. I have the stock firmware to be flashed on to it downloaded. When I put it in to download mode, it constantly connects then disconnects, even when nothing is moving the phone. I tried LG mobile support tool, which seemed like it was going to work, then the phone kept connecting and disconnecting. It also is very selective on when it wants to turn on too. It will only turn on sometimes. Even if I leave it plugged in & charging for hours. All USB drivers are installed and up to date. Any help would be appreciated. Thanks!
I got it figured out. I don't know how to remove this thread though.

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.
Sent from my Nexus 5 using XDA Premium 4 mobile app
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.
Hello,
I have a Verizon S3 (SCH-I535) which I've been using for over a year now. I decided to root the phone about a month ago with TowelRoot and everything seemed fine. But just a few days after I had rooted my phone, Verizon issued their KitKat update for my phone (I dont know why I received the update a few months late). I didn't want to update because I knew that if I did, it would just soft-brick my phone. So I thought I would just connect my phone to Odin and load the stock 4.3 firmware back onto my phone (since deleting the root files won't really have any effect). But when I tried connecting my phone to the computer, the computer won't even recognize it (I had the drivers installed). It charges, but it won't get recognized on any computer I plug it into. After this, I realized that the micro USB module got messed up.After my phone wouldn't connect to the computer, I thought that if I had just soft-bricked the phone by trying to install the update and then restarted the phone from recovery, I could just boot up my phone regularly and I wouldn't get the update anymore. I didn't want the update constantly bugging me every single time I used my phone. But to my dismay, the update downloads once every 24 hours. So I used my phone for a few days, but then I realized I that had another problem, none of the Google apps (Play Store, Google+, Hangouts, etc.) were working. So I decided to clear the cache and memory of all of them and sign out and into Google services again. When I tried signing back in, it would say that I couldn't establish a reliable connection to the server, even if I had really fast internet. Along with these problems, I don't receive notifications from any app even if I turn them on and some apps are starting to crash when I open them up, such as the camera app. I've tried a number of solutions, such as trying to install CyanogenMod through Clockwork, but none of that works because of Verizon's locked bootloader. I've even tried factory resetting, and it still soft-bricks that way. Could anyone please help me with this? Thanks.
Hey guys, let me just start off by saying I have spent almost 8 hours straight today trying to figure this out and dig myself out of a hole I've created for myself, that being said, I'm going to try and be as detailed as possible so you guys know EXACTLY where I am and what I've tried. This post looks long but that's because it is. It's pretty much my entire day's worth of trouble typed out. So just bare with me and see if you guys can help me out here!
I have a T-Mobile Galaxy S4 model: SGH-M919 it has Android 4.4.2. Now on to the problem: I've had this phone for almost a year now and a few months ago I rooted it. Did a simple Youtube tutorial and used Odin to do the work and everything worked out fine. A couple months down the road (yesterday), after using the phone like a teenager, downloading apps and cluttering it up it started to slow down and not run some apps. After thinking about it I decided to factory reset it. All of my contacts, photos, and videos were backed up on Google so I thought "why not?" Well, this is where $#!% hit the fan.. being rooted then factory reset, right before the phone came online it had me answer two questions about the root. Something to the effect of "Do you want to keep root? (This option is not reversible)" I thought since I wasn't using the features I originally rooted the phone for I figured nah just get rid of the root. So the phone did its T-Mobile boot up and started the Initial setup.
Everything up to to this point was fine until I wanted to log in to my Google account during the setup. Please understand that where I am I have full 4G LTE coverage and have access to a pretty fast and sturdy wifi connection. Well, when it came to the google sign in I entered my email and password and it came up with a message reading "Can't Sign in - Can't establish a reliable connection to the server" (believe me i wish that was the only issue) so after reading that, I thought I'd try with my wifi.. nope. Same thing. Since neither my 4g or wifi worked I thought it was Google's servers so I tried again this morning, same thing. (keep in mind at this point i think my phone isn't rooted anymore.) I call the t mobile store and they give me a technical support number, so I call it and I tell them i cant sign into Google. The gentleman told me he cant do anything because he can tell my phones been rooted. Only thing he suggests is to contact Google, well, the customer care number just tells you go to google.com/support and there's nothing there about my problem.
This is where I dig my hole even deeper. I tried another factory reset and up in the top left corner i still see that root text. Even the rooted android symbol pops up before the Samsung logo or t mobile. Since I saw that I thought "ohh it just didn't get unrooted all the way." I look up ways to completely remove a root and a lot of them require plugin your phone into the computer and using Odin to flash a stock firmware on to the device. I went to plug my phone into the usb port but my computer didn't recognize the usb device, having experienced this a long time ago I searched around for the latest Samsung usb drivers and I installed those. Device still isn't recognized. Let me just note before people tell me to use MTP mode or Developer tools> usb debugging or connection mode.. The only thing that happens when plugging my phone via usb is the phone starts charging and my computer makes the trumpet noise like something is plugged in. Other than that, there is NO notification of it being plugged in. The reason i stress this is because I called Samsung technical support at this point and the guy (not gentleman) treated me like a 5 year old and ran me through all of these options after i told him I already did everything he was suggesting, including downloading Samsung Kies 3 and having it install the drivers. It does not pick up the device either.. at this point I looked up ways to remove the root without the computer. I found out you can just go into the root app "SU" or something and theres a remove root option. I jumped on that opportunity and had it removed. I restarted the phone and all the problems still persist, it even still has the root text on the top left when you factory reset it again. However now, even if you factory reset and select the option "keep root," thinking it would bring back the"SU" app it does NOT.
So lets recap. I have a phone that thinks its rooted and even appears rooted to t mobile but doesn't have any of the root apps or privileges or capabilities to fix my Google log in issue (like the host file in filemanager). And I can't re-root to get that app back because none of my 3 usb ports, 3 different usb cables (one being the cord that came with the phone), or any of the ports/cables on someone else's computer will recognize the darn thing to work on that way! I have all these issues that are supposed to fix each other but I can't do any fixing because they cancel each other out too... I'm at a dead end.
In case this isn't the right forum/website/thread/post area etc.. I have this whole message saved in Microsoft Word document so I can repost it anywhere you guys might suggest better results. Any help/advice will be much appreciated.
