No Signal! Help - LG Optimus L9 P760, P765, P768, P769

Hi I have a problem with my LG P760 about the phone line, suddenly there is no signal, if I'm going to do a manual search of the networks me lies quietly but can not connect to them in fact comes an inscription like "the sim can not connect to this network. "The problem is definitely not the card because now I'm using another phone without any problem. I came from dragurom, then I did a restore error with update lg support tool but the problem persists. Someone idea what it could be?? If it was a software problem had to be resolved with the restore?

Maybe your baseband is corrupt. Try to offline flash your original kdz or use LG mobile support tool to recover your phone again.

Did you successfully restore your phone in LG support tool? If not what error you got?
And did your phone network work in Dragurom?

[Q] Problems with Downgrading L9

Hello everyone
I am new to LG phones but quite familiar with modding Sony phones, as all of you know that there are many problems with L9 like not able to move data to sd card, Touch screen sluggishness sometimes and not able to mount the memory card but many of them can be fixed via rooting. But again only V10a and V10c are rootable, i have v10d P765 IND version. I want to degrade the firmware so that i can root the mobile and play with it properly.
I followed the guide KDZ offline flashing method but I am getting error
"cannot connect to internet , check the cable line"
I am following every step, Does anyone know what is this?
Thanks in advance :fingers-crossed:

well did u run shttps ?
did u run windows enabler to ON ?
did u installed proper drivers for phone ?
did u turned of lg pc suite ?
did u installed proper lg mobile support tool ?\
did u instaled android sdk (not required but... still good to have it)
and the most important did u readed the tutorial few times ?
if u have checked all steps as YES then everything should go well.
Just check everything again.
Btw i also get that info when i dont turn on shttps !
PROblem persist
Thanks for the suggestion,
I did everything thats said in the tutorial, flashing started but stopped at update saying, problem with communicating device and PC. as told i tried both modes
1. usb debugging on (mobile normal)
2. software update mode (by holding vol up and connection)
but the problem persist.....i have installed every single driver i supposed to insatlled, but bro its really frustating....I really want to root ....or i have to sell this mobile by swearing never to buy LG mobile...
Your first problem (Please, check internet line and execute program again.) is solved. Correct?
And now you got a "cannot connect to phone" message, right?
Did you try to connect to your phone with LG PC Suite. Because if you can connect and sync your phone then all driver is installed. Download at your local LG website ex. for me http://www.lg.com/th/support-mobile/lg-LGP768F#software, in PC Sync Tab
If you install all drivers when you connect to your PC, you should see new 2 drives (Phone internal SD and External SD)
NOT solved bro
the problem came again, it start showing check the internet cable again.....
i dont know what the problem is?
it worked once but now its not working. It seems that my shttp isnt working properly because i can connect the mobile via internet and check the update, when offline it start showing that again.
Btw i am using automatic offline procedure.vbs program. I think there will be less chance of mistake by this method.
my mobile is being detected perfectly by pc suite and other media, as you mentioned i can see two drives also.
Basically i am standing at the starting problem again...wtf....
Nevermind bro thanks for the help. I have already given you so much headache.:angel:

There is full-working guide for flashing and rooting by me in Development section. Also it seems you missed the Collection of ROMS and Rooting post above in General Section too.
Forget windows enabler or vbscripting and flash offline in simple steps and simply root. perfectly works for P765 and others variants too.
I am with Rooted Stock V10c on P765 India. Working superb with no issue at all since 2 weeks or more.
I followed your guide only
hello,
I am from india too and i am on 10d firmware, i tried your guide only from starting and believe me I followed every single step in your guide but actually I am getting error while updating at 3-6%....
"communication problem between device and PC"
For information I tried software update method and usual mobile on (Debugging on) methods. even tried every single usb port in my PC.
I tried atleast 20 times to restart in different modes but still it donot complete....I am really frustated by its low memory. whats the point of having a quite powerful hardware if I cannot even play games just because of low memory..

I think if its stopping at 3-6% that roughly means the flashing did not start at all upto that poing and you are getting total connect proble. Tried changing cable? Cant ruleout connection problem due to cable with weak transmission. Also a driver issue.
This worked here for everyone on P765. You may try again with proper drivers.
Did you start software upgrade mode by power off your phone and hold volume up button when plug in usb cable? You phone should show software upgrade screen.
I remember that I can flash almost other model/variant on my phone except one, which I cannot remember. If it not compatible with your phone there are error after reboot.

[Q] soft brick after downgrading to v10g

Hi all,
Thanks in advance for any help. I originally was attempting to root my phone following this guide here http://forum.xda-developers.com/showthread.php?t=2277639. I was able to use the software update tool several times to flash to V20B and V20D. After a few tries, I read on the authors forum to flash to v10g as I was having some issues (got the CWM L9 Recovery tool installed, and after booting to it, got stuck on encrypting). So I flashed down to v10g. After that, phone wouldn't boot. So have attempted to use the upgrade tool to flash back to V20D or B and have tried following this thread http://forum.xda-developers.com/showthread.php?t=2085344. Even though I can get the S/W Upgrade screen, the software upgrade tool keeps stopping at 15% and tells me the cellphone is not connected. Even though I had gotten it to work before at this same method, I re-installed the drivers and even tried the whole process on a 2nd computer with no luck. I'm guessing the downgrade to v10g is the cause of the issues I'm having, but do not have any idea at this point how to fix it. I have spent hours searching the forums, but have not found a solution yet, so any help or links to posts that could help would be appreciated.
I have the P769.
And if you happen to know why I get stuck on encrypting after using and rebooting from L9 recovery tool, that would be an added bonus. (found it, looks like it was busybox x, will try when I get phone back up).
I have tried on computer running Win 7 64 bit and Win 8 64 bit.
Thanks!

Hi willevans, if you patched your hosts file for the off line kdz flash method, remember to erase the two lines added.
Good luck.

I followed your directions. It seems like we have made progress but am still having issues. It did install some updated drivers, and with the online LG support Tool, seems to find the connection, but stops due to an error at 15%. I also noticed that the screen goes black on my phone and S/W upgrade is no longer displayed. Don't know if there is a timeout were it does this or it is shutting off because of the update process and not coming back on.

I do not see that option. Let me confirm that we are running the B2CAppSetup (LG Mobile Support Tool) and not the UpTestEX_mod2_marwin (R&D Test Tool) program at this point.
Nvm, it looks like with the update, even running the R&D Test Tool, it takes you to the LG Mobile Support tool which will crash if you have it blocked. Same results when not blocked, stops at 15%.

The only options in the LG Mobile Support Tool is: Options and Help in upper right hand corner. Under options is country/language and Upgrade Recovery. On lte left side shows my model once it is connected and gives me greyed out install usb driver option and start upgrade. Those are the only options.Here is an image of what I have.

Still stops at 15%. I have also tried running fastboot. I get about halfway, but when it comes to the part to reconnect to the phone, it just hangs.
Well, using fastboot, I have got the LG tool to now progress past the analysis part and get to the actual update part, but now stops at 15% there. Progress, but am at a loss at what to try at this point.
To sum up, phone will not boot at this point. Can get to S/W upgrade mode on phone. Phone stops at 15% at update portion.
I have tried the offline and online update methods, along with fastboot (get through the entire steps on the computer, but at end screen shows LG logo with fastboot in corner, don't know if this is normal).
I have tried a few more solutions to no success. Luckily, my phone was still under warranty with T-Mobile for about 2 weeks, so sent it in since it wouldn't turn on (unless you did S/W upgrade mode). Hopefully, they wont notice why. Thank you for your suggestions Bojo.

[Q] Any sollutions for l5 II e460 security error?

Unfortunately after an unsuccessful update I am getting "security error" after powering on my l5 e460. Only thing I can do is to go into the download mode. I tried both the online and offline methods to flash kdz but the result is same. Security error!! The drivers are installed and I do not get an error during the kdz flash but nothing changes. I also tried lgnpst lab tool but couldn't find the proper dll for lg l5 II. Any help would be appreciated. Thanks.
Are you able to start your phone in emergency mode?
DLL is included in appropriate KDZ file. You can use LGExtract tool to get DLL out of that.
Hi dude the solution is update your phone with the LG support tool,

Yes I am able to start in download mode. I also extracted dll and bin file from kdz. But still no chance. The LGNPST tool doesn't recognize the dll file. I tried to register the dll file but couldn't manage. I tried msny kdz files via LG Support tool but the result is the same. Both the online and oflline flashing procedures couldn't manage to get rid of security error. Thanks for your help

Dude I have tried to update my phone many times via both online and offline procedures. the flashing procedures finish due to some interruptions such as reconnecting the phone again alerts. But at the and again and again security error! For instance when I flash a kdz for lg e460, the led light of the home button lights green or red when charging. But when I flash a kdz for lg e455 the led doesn't light. This means that the kdz is flashed successfully. Or at least something has changed inside the phone. But security error issue still remains. Might the reason be because of a hardware issue or recovery issue? By the way the phone is not rooted unfortunately. If it had benn rooted, I could have flashed the recovery or system.img. Any ideas would be appreciated. Thanks for your help

[H820] Never get any update

Hi all.
i just bought at&t unlocked G5 (H820), and it seems i have a problem about "software update".
When i check Android security patch level, its still on "2016-03-01" (Build number: MMB29M, H82010c). Its very outdate, and i cant get any update. already check via software update (OTA), its says i'm on the latest software. I try use LG Bridge, still the same - i dont get any update and i get error "cant find software" or something like that (i dont remember the exact word).
Please, can you guys help me. Is there another way to get Software update?
I dont even have app drawer :crying:
fyi: I already search firmware for H820, but still no luck.
Thanks.
I have a similar problem with my phone, OTA does not work for me.
Download the latest version of LG Bridge and connect your phone, go to Software Update tab and search for update
Thats the only way I got updates and im updating to Nougat with my H860N right now.

Already tried sir. Still no luck.
Everytime i click "Search for update", i always get this error
"Cannot check the software version Try Again". I dont have any problem with USB driver, my phone connect perfectly with LG Bridge and i have the latest version of LG Bridge. I tried to click "Update error recovery" and i get this error message "cannot check phone information".
any idea?
Hmm, I would suggest perhaps try it on another PC (also looks like there are troubles with LGUP+ Macs if you are on one)

I'm on windows sir.
Yeah, maybe i will try it on another PC (even though i dont have any problem when using LG Bridge with G4).
btw, this is my first time buying unlocked phone. i dont know that i need at&t simcard just to get an OTA update.
I think im screwed. haha.
This is also happening to me. Since I've got my phone back from warranty I don't recieve any OTA updates (even though before everything was fine) and LG Bridge is displaying the same error as yours. In my case the reason I think it is because the motherboard was replaced. My phone is an UK model but the new motherboard is made for Europe (my IMEI was changed after this replacement). Maybe something similar happened to your phone. If you can find any solution to this please post it because I'm also interested in resolving this.
