[Q] [Help] LG Optimus G E975 bricked and no method is working to solve the issue!!!

Hi devs
I am an unfortunate soul as my recently purchased LGOG E975 just got bricked. The whole story goes like this -
I successfully rooted the phone one week ago and it was working fine until yesterday when I uninstalled the Google Play Movies app via Root Delete app. The problem started when I restarted the phone - it gave a "Security error" on boot and went into restart loop. Worried I searched at Xda forum for the solution and tried the "TeenyBins" method first (here http://forum.xda-developers.com/showthread.php?t=2249500). But it only aggravated the problem - at 85% of process the phone showed as disconnected from LGNPST and after trying many times the same problem persisted (the process never got to 100%). However the method installed TWRP custom recovery in the phone and a Google Logo replaced the LG logo at boot. Phone was normally booting in download mode and custom recovery but the recovery is unable to do anything - it shows as "Failed" whenever I try to wipe any cache, mount any partition, flash any custom ROM (which I pushed via adb) or take backup. Rather it shows "No OS installed" whenever I reboot, power off etc. TWRP is also showing no data inside sdcard via the inbuilt file manager. What is the problem?
Fed up, I tried LG Support tool - phone is successfully detected in "download mode" (everything is shown including the OS version which means OS is intact). I choose "phone recovery" option in LG support tool and it successfully downloaded the stock firmware (about 1.1 GB wait wait and wait) and when it tried to flash the phone it showed as the phone is not connected and instructed to unplug the phone and restart it and then again connect to PC. I followed everything carefully putting the phone in download mode again but again and again same error......Oh God for heavens sake....
Fed up, I then tried this method (http://forum.xda-developers.com/showthread.php?t=2010624) - downloaded the latest KDZ (>1GB) according to my phone from LG servers and used the KDZ FW Updater to flash the phone but the tool gave error "File extracted error" and I repeated the process again and again but no avail..............here I am, after 48 hours of desperation having a phone with the same **** Google logo on boot and the screen goes black...nothing happens thereafter..
Please forum devs, experts, moderators or any kind soul, I beg you to help me.... :crying:

If yu ve done the second method before instead of lgnpst tool there may b chances of helping yu.... And make sure which bin nd dll file yu flashed...??

OK One question.
Can you get into download mode? Flash MODE?
Follow this
1.Install all drivers LG
2.Download firmware from here http://www.lg-phones.org/official-stock-lg-optimus-g-firmware-rom.html
3.Download http://www.mediafire.com/download/sj5y073xal03ntw/KDZ_FW_UPD_EN.rar
4.Extract KDZ_FW_UPD on desktop
5.Install msxml.exe
6.When done run windows enabler. You will see the icon and left klick on it and choose ON
Now you should se ON at the ICON
7.When done start KDZ_FW_UPD.exe
8.Chose 3GQCT in TYPE and Phone Mode CS_Emergency
9.Then Turn of the Phone. Now hold Vol UP and Vol Down at same time. Hold and plug in the USB cable into your phone
Now you should be in DOWNLOAD mode
10.Now chose your firmware in KDZ File and press Launch Software Update
If it starts to flash dont interrupt it until you see PARAM 1 again. You phone will auto reboot at PAram 95 but dont discconect until you see PARAM 1 again.
If you get bootloop when restart give it 2 min. If it keeps show LG logo then turn of and do FACTORY RESET
Hold Vol up + Power at same TIME i think Now you should get Factory Reset MENU. Now press power again and it should work.
GOOD LUCK

Thanks for your time dear
but I have exactly followed the process you mentioned and unfortunately still got the KDZ extract error. I have downloaded KDZ for my phone from different locations multiple times but none of the KDZ worked with KDZ FW Updater. It looks like the current KDZ FW Updater is unable to handle the large KDZ files (>1GB) of newer phones while it works fine for older smaller KDZs. In this way this updater is a bit outdated. I request the developers to please update this wonderful tool to make it compatible with latest KDZs.

Try using kdz from romania,it has 982 mb and it's 10D.

But i flashed mine KDZ and its above 1GB and it extracted without issue. It must be something with your PC or something.
Mine extracted without issues
I think you have CORRUPT DOWNLOADS.
Do you unzip the KDZ file from the RAR? Or do you point KDZ Updater to the RAR file? You must unpack RAR so you file will be shown as E97510B_00.KDZ this is the Europe Open Version.
Remember if you unrar the file check if any errors coming when unpacking. If so then your RAR is corrupted and you need to redownload.
'did you RUN Updater as ADMIN?
Download this version of the KDZ European Open

http://www.lg-phones.org/official-stock-lg-optimus-g-firmware-rom.html
It must WORK.

I have the .KDZ file and not .rar but I did not run the program as admin so will try again. It may be a corrupt download so will download again.
One question though, my phone is E97510E_00 (Indian version) so can I flash with the 10B open Europ. version KDZ you mentioned above?

Basically all firmwares are identical.the only differences are operator related. If you can find what are the 4g/lte frequencies of your operator,i could tell you what europe firmware to flash.if you don't have/want 4g,i guess you could flash the latest 10D european kdz without problems.

Mate just flash EU version so you can have working phone. If you sucess you can seek for answer later to flash indian ver.

exactly same problem!
hello my friend,
i have exactly the same problem as you with the same results.today ill try doing this in a desktop and see if the extract problem is gone...it drives me crazy.
please if yu fing something write it here...you ll save me!thank you!
p.s. i have f180 U+ edition

ok i found solution combining all of what i ve read..(and read a lot)
1)find a custom rom (i used avatar) but unzip it and go to \META-INF\com\google\android and open updater script with notepad.Delete this "(assert(getprop("ro.product.device") == "e975" || getprop("ro.build.product") == "e975");"
then save the file.
go to first folder that u unzipped and take MetaInf,boot img and system and put them in a new zip.
2)so since u have twrp in your telephone,push with adb the zip from step 1 inside the phone (how to push a rom here)
3)the phone will normally open when you reboot.if you dont have signal go here and download your phones modem.Copy it through your pc to your phone and then reboot again to recovery mode and install this file(do not unzip it)
clear cache,do a factory reset and in the next boot you ll be allright!

Hi,
Really excited, but can u please tell me the step by step procedure. My phone is a F180L korean Sim and i really dont know which is my actual make.. i mean like E973 or E975. I bought this phone to india and unfortunately its U+ sim locked and i was unable to use this phone in indian networks. Hence after going trough this forum, i learned how to change a firmware and how to convert this phone to E975 and i downloaded one for india from the official LG site and there were KDZ extraction error. i tried it with the LG PC sync method and its showing the memory is low and free up some space in the memory. but after downloading a firmware for Europe, i could update my phone into E975, but my indian sim is not getting connected. So i request everyone for a solution. I tried many things already and soft bricked many times.. luckily i could recover it using LG support.
SO KINDLY TELL US HOW U DID IT WITH THE AVATAR ROM AND WHAT DO U MEAN BY \META-INF\com\google\android.
Many thanks

so this is what i did.
1.use LGNPST prog with the small file for installing TWRP in your phone (see how here)
2.Download a custom ROM.I used this.The file will be in ZIP format/
3.copy your rom in a new folder.Rightclick on ROM and press extract here.The extracted files will be 2 folders (METAINF,SYSTEM) and boot.img.Open META-INF\com\google\android (these are folders) and there will be a file "updater script ".Right click on this file and select open with notepad.Then delete the following " (assert(getprop("ro.product.device") == "e975" || getprop("ro.build.product") == "e975"); ".Press ctrl+s to save the file.
4.Go to the starting folder,select again METAINF,SYSTEM and boot.img ,right click them and press add to archive(with winrar).In there give a name and be sure to select zi compression.So this new ZIP you've just created is the new ROM.
5.Now you have to send the ZIP you created to your phone.This can be done with ADB push.To read how to do it please read here
6.Once you transfer that file into phone you have to disconnect your phone and press vol+ button and then power on.This is FASTBOOT.Press 2 time the vol- button so it says RECOVERY MODE.Then press the power button and wait to open the TWRP menu.
7.Now that you are in TWRP select wipe and wipe dalvik,cache and do factory reset.Then go to install and youll see the pushed ZIP file that you transfered before.Click on this and press install.
8.After a while it will write that is done.Do a reboot and the new ROM will be fine.
9.If it opens and you dont have signal go to this site here and download the modem for your phone.Mine worked with Korean version modem.I dont know what you should install for Pakistan unfortunatelly.So when you download it,send it in your phone through usb connection (now your phone works,no need of ADB push) and then go to TWRP in recovery mode and install modem like the way you installed the ROM before.Wipe data again and do a factory reset and then your phone should be ok.
BTW you have to know that these ROMS have some bugs but you can do epic customization and the guys always update the rom over the air to do it more stable.
If you have any question feel free to make them!Good luck!

Thanks a Lot MafiaGR....
I didn't tried this yet as i did a different method and i am using it on trial basis. is it works.. then i am more than happy enough to continue... let me explain what i did.. I have rooted my F180L korean U+ sim unlocked phone with motochopper. After rooting the same, then i unlocked my bootlocker with freegee-beta (many thanks to Shell). Then i downloaded a kdz file (E97510D_00.kdz , Europe Open) from the LG server. then i updated the same by putting my phone in download mode (volume up+volume down + USB connected + power ON) and updated with KDZ updated program.. after quite some time my phone got rebooted with E975 Europe Open firmware. Even after this i was unable to get indian network in the phone. So Using Rom manager, i downloaded CyanogenMod 10.1 Rom with GApps and flashed my ROM again. Now my phone is getting connected with indian network. but the problem i am facing is with my network not getting registered... i can find about 12 networks in my phone but unable to register into any of them...Need help from u guys...
Thanks in advance

Finally I got the problem solved and my phone back !!
Unfortunately nothing worked for me as suggested by you, guys may be I was doing something wrong or else.
Finally I decided to contact LG Service Center in my city and after initial try they told me that "the phone is not getting connected in flashing mode" and I had to submit the phone to them. Next day they called me and told that there is a hardware problem and a "part/PCB" will be replaced within next 7 days. And today they called me again with the good news - your phone has been repaired and I can pick it up anytime. Elated I got the phone within an hour, live and kicking. Thank God I got my loving phone back and most importantly they did not detected that the phone was rooted and thus out of warranty. Lucky me!!! :laugh:
Any way thanks everyone for your prompt help....:good:

maybe you hae to try diferent modems for the mobile phone until you find the right one.Mine works with the Korean modem although i live in Greece.You may have to find exactly in what frquency your provider works and then see where in the world a provider has exasctly the same frequency as yours,and then download the modem drivers from the LGOGs that work in this country.
Hope it works!

well this is the best choice,even if they say that if you root your mobile phone,you lose the guarantee.But its a bit difficult for me to do that since i ordered the mobile phone from Chine and i live in Greece!So i should give away my phone a long time to get fixed and i cant wait!XD

You are absolutely correct. The problem for me was with the Modem for sure. I flashed with a Nexus 4 modem in my phone and i could register network in my phone. but the problem now is that the signal is very weak. I tried flashing many modems like E970 Att, then E973 Tellus and few more.. but i couldnt get a better signal. if the signal is good, then the sim is not getting registered. i tried to search for an indian modem for E975 which i couldnt find.. moreover i am unable to download the indian/thailand/hongkong firmwares from LG official site as its saying that the Access is denied. Please help me with those links as i am really desperate to use my phone...
Thanks again

[F460K Only!] Unbricking package and guide

Finally I've managed to unbrick the phone after the stupid fail with the configs tuning.
Warning: Everything will be wiped from the internal storage. I mean NO ONE BYTE WILL SURVIVE.
First of all download the archive I've prepared. It content is:
LG Mobile driver – LGUnitedMobileDriver_S51MAN312AP22_ML_WHQL_Ver_3.12.3
LG Flash Tool – Setup_LGFlashTool_1.8.1.1023
Proprietary DLL for the phone – LGF460K_20140708_LGFLASHv160
And the diamond – LGF460KAT-00-V10o-KT-KR-OCT-22-2014+0.tot
Take it here: http://unl.su/f460k_unbrick.zip
Mirror: https://mega.co.nz/#!aA5gET6D!fE5brJiM6Okv0kmzrjoZ-dEmAe78KslJMuUMSKBWyxQ
After you have managed to download and unpack it, do the following:
1. Disconnect the phone
2. Install the drivers (this version differs from S50 for about 60 kilobytes but they're important for the F460 series phones)
3. Follow this illustrated flashing guide: http://forum.xda-developers.com/showthread.php?t=2772199
4. If the phone is stuck at blue screen with the number "3" for longer than 10 minutes – take out the cable, battery, and pu the battery back, connecting the cable is unnecessary. Then power on the phone.
5. After reboot an Android with revolving crystal will appear for about 30 seconds - it's ok.
6. Wait for Olleh logo.
7. Here you are. Thanks meter is on the left.

[Solution] if you flashed the wrong firmware on your LG G2

First of all I want to Thank cybertag (a member at reddit.com) whose help made me find this solution. And sorry if my English is not good, it is not my first language. As I don't have enough posts here, XDA restricts me to post external links so this is the best I could do. I will add links to the files needed once i am allowed.
A few days ago I was tinkering with after my lg g2 ls-980, the sprint version of lg g2, rooted but no custom recovery installed and I made my first mistake of changing the model number from ls-980 to D802 in built.prop file thinking that it will only change the model number shown in the hardware information and restarted the phone. Once my phone booted up after that restart everything was crashing. There was a huge number of crash reports popping on the screen and I was not able to use anything. So I downloaded the .tot files of the stock firmwares LS980ZVC and LS980ZVE (don't know why but I downloaded both) along with the .dll file needed to flash the firmware for ls980 and when I tried to flash the firmware booting the phone in download mode and using the LG Flash tool but it gave me an error saying that the firmware does not match with model number of my phone. Both firmwares gave the same error. My phone and the flash tool both were thinking it was D802 while it was not.
Now i made my second mistake and downloaded the stock firmware for D802 and flashed it using LG flash tool. The firmware was flashed successfully without any error, but when the phone booted up after the flash the touch screen was behaving funny and phone restarted every 15-20 seconds because this firmware was not meant to be used with LS-980. I was unable to do anything the way touch screen was behaving.
I spent most of my time for the next few days googling for the solution and searching on XDA and also on reddit. I found multiple threads reporting that a generic no-check DLL file is the savior in this situation, but when I tried to run it I get continuous errors telling me the following: "CrossDL [D8012] to [LS-980]". Then i found this thread by cybertag on reddit which lead me to the right direction. It suggested to hex edit the .tot file for ls-980 so that the flash tool thinks that it is for D802. So I grabbed a hex editor and found the first mention of LS-980 and changed it to D802, saved the file and tried o flash it but it was still giving different errors. Then someone suggested it only works if you edit the .tot firmware in linux based OS. So i installed ubuntu OS on a virtual machine and tried editing the firmware in that OS using Bless Hex editor, still no success in flashing. Then I tried editing in pinguy OS but in vain. Then I found FlexHex for windows and used it for editing the LS980ZVC.tot firmware did the same thing, found the first mention of LS-980 and changed it to D802, saved the file, flashed it and bingo! the flash tool gave no error this time and flashed the phone successfully.
Now there was another problem. When the phone rebooted after flashing the firmware it got stuck on LG logo forever. And when I tried to boot it into download mode, the download mode was gone and it took me to fastboot mode. The phone was stuck in bootloop and there was no download mode anymore. Now after more searching i found a method to resolve this problem. Downloaded the aboot.img and laf.img partitons for LS980ZVC and flashed both using fastboot commands. Tried to boot into the download mode again and it worked and i was in download mode one again. When I checked the phone model was changed back to LS-980, the original one. Flashed the LS980ZVE firmware from original .tot file as it was the latest version available to date and it flashed without any error. When the phone rebooted after completing the flashing process, it was as good as new, up and running the original stock kitkat rom for this model. Tested and tried everything and never noticed any issue.

Thank you @tauheed that will help a lot of people I'm sure.

the only possible option is to flash the aboot.img and laf.img partitions. But we need to find a way to do so in your phone's current state. Things can be a lot easier if you could manage to get into fastboot mode.

You have to edit the first mention of the model number in the hex editor. Don't mess with anything else.

I am the same problem as yours with another phone I have. It is a D800 which was wrongly flashed to D802. After flashing the D800 firmware with the model name edited, it is stuck on LG logo and it won't go to download mode either.

Not yet. I'm still waiting...total dead phone now.

[Q] Help!! - LG G3 stuck in download mode

Hi guys I'm a newbie here and this is my first time posting.
I was trying to flash stock on my LG G3 but I made a really really stupid mistake. I used the flashtool found over here at http://forum.xda-developers.com/showthread.php?t=2799647 but I had used the wrong tot file. Now my phone is stuck in download mode. I don't think my phone is hard bricked because it still boots up but only to the download mode no matter what I press. I also can't access my custom recovery now. I have tried flashing with kdz file for my phone using the LG Flash tool 2014 but on the LG Mobile Support Tool the progress bar goes up to 10/11% during the s/w update and I get an error after waiting for half an hour and the progress bar on my phone's firmware update screen only goes up by 2% at most. I can't find the tot file for my phone version to flash with so I'm stuck here. Help please?
phone version : v20g-sea-xx

hi , i have the same problem.

Did you try to flash the correct .tot file again?
Check the logs for the error which is generated from LG flash tool 2014.
May be you have cross D/L error due to wrong tot file flash.

these devices have locked bootloaders. how did u install twrp?
best bet would to be to find what ever firmware device was on and reflash it with lg up or flash tool if u still have download mode.

Thanks for your reply.
I really don't know what i did to install twrp.
I try to use flash tool but doesn't detect my phone.

With flash tool goto device manager on pc.
click ports and com get into settings on it and change com port to 41
and have device in download mode powered off volume up + insert usb cord from pc

@imider I have the same problem trying to recover from a hardbrick on H815. Tell me what happens if you pull battery, plug bag, hold VOL DOWN and insert USB. Do you get fastboot?
EDIT: You might be able to flash it in FlashTool (I said no before) because I see you have Official Status not MODIFIED.

Thanks for your reply guys.
I manage to flash it with LGUP with a TOT that I downloaded.
Thanks.

Congrat @imider ,
maybe you can share what you did to fix your G4

Hello,
First I wanted to flash a clean rom on LG G4 H810 and I don't know what I did but the flash doesn't work and my phone has a black screen even the logo is not displayed.
When I connect my phone to my PC (windows 10) it's detected as "Qualcomm HS-USB QDLoader 9008".
Now this is the step that I follow to repair my phone :
1) I follow this tuto : https://forum.xda-developers.com/g4/help/lg-g4-bricked-qualcomm-hs-usb-qdloader-t3609999
2) After that I can enter download mode
3) I flashed a tot with LGUP
I hope it will help.
