Hi, I have an LG Optimus C for Cricket wireless phone. I rooted it using gingerbreak, worked great, but then I did not know what I was doing and installed ROM Manager and installed cyanogen7 mod with ROM Manager. Once Cyanogen7 installed onto my device I ran it and my phone restarted. However it now wont startup. It stays frozen at the LG logo. I tried connecting it to my laptop- my laptop does not read it, tried pressing the home key, down arrow, and on button for emergency mode- no response. Nothing thus far has worked.
My computer does tho read, in the device page (Windows 7), LGE Bluetooth TransPort and LGE Virtual Modem. Thus far I havent found anything that could revive my phone using these.
If there are any tips to help recover my phone I would greatly appreciate it.
Thanks.

I have a LG Optimus L9 P769 (T-Mobile). It came with ICS 4.0.4, but did the OTA to get it updated to V20F JB. Shortly after, I found the LGPwn.apk and used that to root. I used Titanium Backup to remove bloatware. I have yet to go any farther with modding.
Ok, before rooting, I connected my phone to my Dell with Windows 7, installed the drivers for all 4 modes available in my phone. I installed LG drivers and PC Suite for the PC. Connection worked perfectly.
As I continued to learn, I installed ADB on my PC. This is when I noticed that my PC no longer recognizes my phone. LG PC Suite can't see it, nor can ADB. My assumption was that it was due to root. So in an attempt to remedy, I used Titanium Backup to put everything back in place that I had removed from the phone. Then went into SuperSu and did full unroot. Rebooted the phone, rebooted the PC. No change.
I uninstalled all LG drivers and LG PC Suite and then reinstalled again. Rebooted phone and PC again. Tried 4 different USB cables. All to no avail. Does anyone have any ideas or suggestions that I could try to get this PC to see my phone again? No rush and not a big deal. I can always re-root...but without ADB, I don't see much hope for much more than that.
(I did search the forums, and to my dismay, didn't find a solution that seemed to help. Doesn't mean there isn't one or I didn't overlook one. Thanks in advance.)
(Also, I have tried this with USB Debugging on and off.)
I managed to get my android back (thanks T3HGOOGL3G33K). I haven't tried to connect to my PC yet. I will update once again when I have had time to test it.
Ok...so I had to do all the work on my PC, save it to my SD card, and then flash using CWM by Artas182x. I uninstalled and reinstalled all LG drivers again and rebooted my PC. Now, the PC is seeing the device, but saying it can't install the drivers for such as MTP, Charge only, Camera, and LG Software. ADB isn't seeing it either when I use "adb\sdk\platform-tools\adb devices". IDK!
I recommended trying another USB port or check the connection. It sounds like the cable isn't connecting to your phone properly.

Thanks @Kuma. I'll try a different port and see if that helps. My goal is just to familiarize myself with adb. (Windows now sees the phone, just doesn't install the drivers. That's why adb can't see it I am assuming.)

@Kuma...I don't know what I did different, but I tried a different cable in a different USB port and to my surprise all drivers loaded right away. Thanks again. I swear I have done this. Maybe I just had to stand on one foot...lol.
Learning on my LG Optimus L9 P769 v20h Rooted and CWM by Artas182x with a few mods and tweaks.
Hi all, I introduce myself, I am Franco Paladini, First Son.
Well let's get my phone will not turn on, (on but not quite, sticks to the logo of the operator) can not have it connected to the PC, which is the worst.
I commented as was my dear LG L9:
Windows :8.1 pro
Phone: LG P778G (P768 board)
ROM: Stock JB (V20B Personal Argentina)
Kernel: Stock
Root: Yes
It all started when you activate or re-activate a tweak to the "Android Tweaker 2" application. Previously it had already activated some as battery life, performance, multimedia, etc. All tested walked 10 points. But I happened to go over those who had already turned and noticed that some had not been activated, immediately afterwards the turn, I remember that was the voltage Flash, JPEG quality, and I think that caused the problem persistence hw ui. This caused the restart not pass the logo of the operator. I am no expert on the subject but not a rookie, I thought it would be easy flash, as he had done previously with other devices, and with this also but had flashed with the device running all ok. Now the problem is that the computer does not recognize my phone, or cell phone does not connect well with pc. When I plug in download mode (SW / UPGRADE) does not install any driver. When I plug in recovery mode (stock not cwm not TWRP) some drivers but not the OMAP, only androidnet installed sooner, but soon turned off to not connect ever. Or turning off or restarting anyway connected, please help! Will thank a lot and was investigating several hours and not be able to connect, have reinstalled drivers, have tried different versions but none of them work, I'm desperate, it IS URGENT! I can spend the Device Manager list of windows or what they may.
Hello everyone i need help!
I have LG G3 Sprint(LS990), its a long story how i get into this problem so ill be short.
I flashed my phone few times and got bricked my phone. now i stuck on LG logo loop it continuously shows me LG logo. Recovery and Download modes not working anymore so i cant flash a ROM right now. after few days of researching i find the way how to make download mode work with laf.img i got everything i need LG driver installed , adb installed on my computer and i got that laf.img for lg g3 ls990 the only problem right now i have is that i can't connect my LG phone to PC, windows doesn't see any changes in device manager when i connect cable.
So here is the question: how can i make my Phone connect to PC while im stuck in fastboot. (i already tried few different Windows PC and Linux also used 5 different cables starting from original one end with other phone cables but still can't make my LG get connected to PC so i can flash a laf.img file to make my download mode work. If you have any other solution ill be happy to accept and try it. Hope for quick response, as its the only phone i got at the moment and its been a few days already that i don't have phone, so my friends start think that im dead or lost already
P.S sorry for poor English
Never could resolve it?
Hi all
Recently, my optimus L9 (the P760), has started to get popups saying ''the process com.android.phone has stopped."
This started when I turned on my phone and suddenly I got pop-ups of multiple apps and processes being stopped.
Then the phone was suddenly off, without having given any kind of warning that it was going to turn off..
Then I restarted it, it got stuck on the LG logo for a while (didn't count, was about 1-5 mins) and then it said 'Encrypting' (under which I can see something I presume is a loading bar, but it's not loading) And under Encrypting, it has a button which says 'Reset phone', which won't work. I've tried it several times, restarted the phone (which also took 1-5 mins) several times, and have looked for solved threads about this on xda, as well as other forums..
There have been several threads like this, but none seems to be solved. That is the reason why I open this new thread.
My pc won't recognize the lg when I try connecting it either.. Nothing seems to be able to fix this, but my warranty has passed due to it being older than 2 years..
I really hope you guys can help me, thanks a lot!

The final production run of L9s featured an encrypted bootloader, phones manufactured in 2013, if bought until early '13 this cannot be the case.
Anyway this means the phone is bricked, if you did not activate Android' s encryption feature.
The LG recovery tool should ve able to fix it in download mode. There are driver problems under Windows 8&10, but download mode should work and is also the final option before sending it in or dumping it.
For download mode switch phone off, then press Vol- while plugging the phone in and wait until it switches on by itself. Activating download mode after an off-on-off sequence seems to help when even download mode doesn't work as supposed. Seems to do the same as taking out the battery in between tries.
This was the last issue I had before my p760 got trashed by this tool http://forum.xda-developers.com/showthread.php?t=2748384 I wish you luck though.
There's various driver issues in the various connection modes the phone can assume.
First there's more trouble with Windows newer than Seven. This affects Fastboot and generally the recognition under Windows. And with a custom rom the LG drivers may not recognize the phone, thus all LG tools will fail too.
Best support is gained with two sets of drivers installed: LG usb drivers and Google SDK usb drivers.
With Artas' CM11, the Google drivers provided support for non-LG tools and ADB commands. The LG drivers only recognized the phone in Download mode and were necessary for unbricking it, as all tools for flashing KDZ files are based on LG's own tool, which needs the LG drivers.
The driver installation is less difficult on Win10 compared to 8.1, run the setup to install both ones.
On Win8.1 you may have to manually assign the Google drivers after their installation in device manager, they' re either found in the Android Phone category or the ADB interfaces one, while the LG ones sit invisible(!) in the other category(phone not recognized, remember?), but the phone recognition will be triggered by attaching it in download mode, and a virtual COM port will be installed.
Hopefully this was confusing, weird and silly enough, but if you manage to get it right, unbricking the phone is still quite possible.
My LG L9 Optimus P769BK (T-Mobile) is stuck on Boot Logo. Hard reset or any other reset procedure in this world does not recover the phone to a normal state.
History:
-I rooted the phone a few months ago in order to get rid of some of the bloatware
-Ever since adware/malware keeps coming which made my wife's life miserable
- I unrooted it but that didn't change anything, the malware now resides within system apps so the misery continues
-The USB drivers are installed and the connection shows three entries in Device Manager
-LGE Mobile USB Modem
-LGE Mobile USB Serial Port
-LGE Mobile Composite USB Device
These are shown only when the phone is in download mode (VolUp + USB Cable In)
The only software that communicates with the phone and recognizes the USB port connected (Com41) is the LG Flash Tool V1.8.1.
Unfortunately this software processes the first 80% successfully until the reset stage after which the phone get stuck at the bootup logo (non-responsive) and never finishes the started flashing process.
I just want to re-flash it with stock ROM for which I downloaded v20h_00.kdz and converted the other required DLL, FLS and BIN files.
I know this is an older model but it was seldom used and I don't want to trash it. Thanks for any response in advance.
PC Desktop: Windows 7, x32, Clean Installation just for this purpose
Update: OMAP driver added
I noticed that I was missing OMAP drivers that are specific for the TI chip this model uses and I did install them. Now the phone has a new entry in Device Manager as Portable Devices where two drives/partitions are listed (F:\ and G:\) These are visible while the phone is stuck on the boot LG logo. The LG Flashing tool still can't continue after the reset at 80% so there is no really any progress yet. Any clue anyone?
Problem solved
I finally solved my problem with LG-P769
I don't know why I couldn't succeed earlier but it turned out using a laptop is a bad idea. I tried Windows XP, Windows 7 and Windows 10. The final solution worked on my desktop with clean Windows 7. The solution was using the trick with Small HTTP server. I don't know why it didn't work earlier but it seems another thread gave me a little bit more details that I missed at the beginning (maybe the server settings)
Anyway, it seems that this phone model was long time forgotten since there was not a single reply to my original post except my two updates so it turned out I was just talking to my self loud, LOL.
Anyway, I would like to thank this forum for most advanced postings regarding the Android branch of cell phones. Regards to whoever found this interesting enough to read.
