Hey Guys,
First post and i already got a problem because i messed up very much
I used to have Cyanogenmod 11 on my Optimus G, but i got several crashes and i wasnt completely fine with it so i wanted to try something new. So i updated my bootloader from CWM to TWRP and wanted to flash Artmod 5.2 Rom. I was a bit fast with my wiping, so i accidentally wiped the whole phone, so that everything was gone: Cyanogenmod, new Artmod rom i wanted to flash just everything.
I read a bit and thought it shouldnt be a problem then to just sideload the new rom, which i tried to do. I used adb sideload to put Artmod on the phone, everything was fine, flashing went through but i got stuck at the LG boot logo at the start of the phone. I waited like 30 minutes and nothing did change, so i thought something was not right.
I then just wanted to go back to cyanogenmod, tried to flash that through the adb sideload procedure but i got an error which said "error executing updater binary in zip 'tmp/sideload.zip'".
I was kinda thinking something really messed up so i tried to revert the phone to stock rom with the correct KDZ file i searched with the tool linked in the FAQ, everything downloaded but when i tried to flash the KDZ it gave me an error like this:
"12:03:59 Launching SW update
12:03:59 Unpacking KDZ
12:05:10 KDZ file extracted
12:05:11 Extract file error
12:05:13
===FINISH===="
So i searched the forums again and noticed that it should be a problem with the KDZ updater tool because the KDZ file was too big to get flashed properly. I wanted to try the LG Flash Tool 2014 then which is provided here in the forums and should work, it extracted the KDZ file, then opened the LG Mobile Support Tool to flash the file on the phone but there i start to get errors again, it either said that i am already on the correct up to date software version or that i need to disconnect the USB cable, remove the battery, insert it again, restart and try again.
I used several tools for that, i even tried it with an offline method that i found in a german forum, but every method got me the same errors, so i couldn't even go back to stock anymore.
I once tried to flash Cyanogenmod then again when i realized that the error message also told me "This Rom is for a "E975", this is a "GEE"" which i did not completely understand because it should be the total same? I edited the Updater-Script in the Zip file of the rom then and removed the part where it checks for that (1st line actually), then the rom did flash properly, phone started to boot (Cyanogenmod Boot Logo was shown) but when the boot was over i got the message:
"Type Password to Decrypt Storage" with a keyboard to enter the password. (I did never set up any password for that).
Now i am completely confused what i can do the recover my phone, either to stock or just to another rom, every method i tried did not work and i dont have any other ideas.
I can go into Fastboot, Recovery and Downloadmode, but when i tried to wipe again in Recovery it says that it cant mount my data mount point (probably because the storage is encrypted).
Somebody told me to do a hard reset with the keys "Volume down and power" which i tired several times, but everything i get is just the Google boot logo and then happens nothing or i get the Google logo, then the LG logo but after that i get stuck again, I cant seem to go into the "Hard Reset" menu which i should get into with that keys.
Anybody can help me what I could try or got a solution for this? I would be very thankful. I don't wanna loose my phone

Don't worry, that's pretty standard scenario for the first post...

Flash Tool 2014 works great for me every time, so try it again. Make sure you disconnect from the Internet before running it (yank out your LAN cable, or disable your WiFi), so it doesn't attempt to connect to LG servers. And don't forget to put your KDZ file in the same directory with the tool. It should go through just fine. That's by far the easiest method to revert back to stock, to get you to a clean starting point.

Umm... No, they are not the same. E975 is "geehrc", and there is no such OEM ID as "gee". There are many different OG variants. For the cross-reference between the models and OEM IDs, you can look here. Generally, you should stick to the ROMs that are designed for your model, unless you know exactly what you are doing, when trying to flash a ROM from a different platform.

Well i tried Flash Tool 2014 again and seem to get the same error that wants me to disconnects as it stops at the same position like it always did, also doesn't matter if I am connected to the internet or not, everytime it doesn't run through. This time I couldn't even read the stuff that was written in the LG Mobile Support tool because it only shows "????".
Heres a Screenshot:
The settings i made should be the right ones I think, the phone does get recognized by the computer when i plug it in because of the sound that windows makes.
I clearly dont't know what I can try anymore...
And according to the roms: well i only used roms for the E975, which is exactly my phone model, thats why i was wondering about that error message i got
Artmod is for E975, the CM11 was for E975, i even tried Mokee rom but i always got same error messages...
Nobody got another idea? I really am confused because if i can enter downloadmode and recovery there should be a way to get my phone back working.
Anybody knows where i can get maybe some older KDZ Files to go to 4.1.2 Stock rom and try to flash these?
problem

I don't know why you are seeing "???", but here is a couple of things regarding the settings, based on your screenshot:
1. Type should be CDMA (yours is 3GQCT).
2. PhoneMode should be DIAG (yours is CS_EMERGENCY).
3. I would suggest using CSE Flash for a full format (you are using Normal Flash).
Remember, this is a hacked tool, so the settings might not make perfect sense, comparing to the original ones. Just try following the instructions in the OP of the Flash Tool 2014 thread. Like I said, works every time for me...

I don't know why i see "???" also, but it didn't matter
I just tried the settings you told and used CSE Flash which worked out really well.
No i am back to 4.4.2 LG Stock rom. I think the root is gone now, but one thing i wanna ask is if my bootloader is still unlocked and custom recovery is still on it?
Anyway, thank you so so much! I appreciate your help! Thank you!

Glad to hear you are back in business. After flashing KDZ, the root is definitely gone, your BL is locked, and the recovery is stock. You will need to do all the necessary steps again: root, unlock the BL and flash custom recovery.
I was trying to install a new rom for my LG optimus G Pro F240, and after wiping in CWM recovery, I noticed that I downloaded the wrong rom, so I rebooted without thinking.
There was no way to get back into recovery, so I had to flash a new kdz using download mode and LG Flash Tool 2014, but upon flashing the new kdz, I get no network signal. I've noticed that the new version of android after flashing is 4.4.2, while the old one was 4.1.2, and also, it is now identified as a LG F240S in the android information, but previously only identified as LG F240. Upon opening the back of the phone, it says F240S/L 0227 down the bottom, F240 0025 on the bottom left, and F240S 0303 on the top right. Which model is my phone really? And where can I get a kdz that will make the network connection work again?
Edit: After attempting to flash F240S10W_00.kdz onto it, it was stuck on the SK telecom screen. Now I can't even flash the F240S20F_00.kdz file that previously worked (without network connection) because LG Flash Tool says that there is a problem with communication between cellphone and PC, this is what it looks like: puu.sh/gkpFJ/f669e8ff56 .png (Remove space)
Please help! How can I at least flash the other kdz file back onto it? I have an idea once that is done, I have my old, original rom backed up to my external sd, so if I can install any kdz that works or at least get into CWM, I can fix my phone, but even that isn't possible right now.

Model written on sticker under battery (Where your IMEI number is written) is actual model of the phone. Just remove the battery and read from sticker. All three version's lollipop Android 5 is out, here I have posted the links. Download the respective model's KDZ to get back signals:

Thanks for the help! It says on the sticker:

then my imei and s/n
Which model is my phone, and which version do I download for it?
Edit: And I still can't flash a kdz onto there as I still have the same problem D:
How do I flash a kdz if LG Flash Tool won't let me? Any ideas anyone?

It is not going into "Download Mode" ?? BTW such stickers with no variant name are very common for "refurbished" G Pro, I fear you got a refurb. You might have to install L, S and K one by one to see which one works.

Yes, I think I also got a refurbished, it was advertised as brand new and was a suspiciously low price, however, that's not a problem, it was working fine before I screwed up, so it is my fault.
Anyway, I managed to get it into download mode and got LG Flash Tool working, and got the lollipop that Waxim1 linked above for the F240S, the one for the F240L didn't work so I assume this phone is indeed a F240s. The only persisting problem now is the lack of network connection, how can I make it work again? I've tried rerooting, but no matter what I try, I can't root the phone now, and therefore can't install CWM in order to restore my working rom. Any ideas?

You cannot root and install CWM on lollipop yet. For that, you need to install kitkat rom, here is KDZ linke for Kit kat F240S. Install it and root and install CWM. Hit Thanks button if it helped you

I already had that kdz, but I installed it again anyway, and managed to root and install CWM and restore backup from sd card, but now even on my backup, I still get no signal? What should I do? Installing these kdz's seems to have broken my network, how can I fix this?

Did you take EFS backup with freegee?? You can restore it.
Further, go to about phone and see if your IMEI number is shown there or not.
If you do not get signal and your IMEI number is correct, just flash stock kitkat KDZ and update to next version via WIFI, you will get the network. Then you can root and install any other rom.

No I didn't back up EFS, but my IMEI is still being shown as the correct one. I tried installing kitkat kdz, but this time, instead of overwriting my stuff, it is still there, but just with new kdz, and I would keep getting android.com.phone has stopped working over and over again, and the phone would eventually just reboot itself. I've tried flashing different kdz's and still get the same result, what should I do now?

Are you flashing KDZ as "CSE" flash or Normal flash? It needs to be factory reset. Turn off the phone, press Volume up+home+power and select factory reset. OR flash KDZ as CSE instead of Normal flash. Once KDZ is installed, update it to next official version from your cell phone's menu.

I've been using CSE flash, and that is what it did. Volume up + home + power didn't work, but I got the phone to reboot into recovery via adb command, and the recovery screen just shows an android icon with a warning icon, no buttons to select. I'll try normal flash and cse flash again.
Edit: After flashing, both normal and CSE, using the default 4.4.2 kdz, it is stuck on the SK telecom screen, it constantly restarts. How can I fix this phone? Really don't want to buy a new phone, I just bought this one. Thanks in advance for any help guys!
Edit 2: NVM, I figured out how to factory hard reset it, and got the kdz for 4.4.2 working once again, but upon trying to update from the phone, it says I'm using the latest version. My signal is, as expected, still not working. My baseband and IMEI are shown as the correct ones. I also tried flashing 4.1.2 kdz for f240s and get the same result, it still doesn't even let me update from phone. Perhaps the phone was network unlocked when I received it, and flashing a new kdz locked it again. Any ideas?
Any fixes? It would be great if I didn't have to get rid of this phone

You are flashing the wrong recovery for your model. It seems your phone is refurbished with a different board. So make sure your model and then flash recovery.Or try d850 recovery. Because most refurbished have d850 board.

That's the problem try to understand. Refurbished are meddled with everything. If you want to make sure the model number. Open your phone. Your model will be written or board.

Refurbished phones have changed or tempered IMEI numbers. IMEI would say d855 but board inside phone is mostly changed.

Not really usually the Imei number is correct so if somehow u brick the device at least u could save it by reflashing the software..other sensors maybe replaced I have experienced many converted phones so I know
Hello to all of you,
Thanks in advance for any help you can provide.
I bought second hand a LG G4 H815 with CyanogenMod 14 already installed on it.
Everything was fine until I installed my Ebanking apps, that would not function with an unlocked bootloader. I needed to return to a clean factory safe state...
It was the second time I flashed a rom in my whole life, the first one was a Galaxy S plus years ago.
I followed all the instructions for the KDZ flash in this tutorial but I stumbled upon a "Upgrade stopped due to error" in LG flash tool.
I retried 3 or 4 times but with no luck. I verified that the ROM was correct for my model and it was. European and all...
I tried LGUP but my phone is unknown ( at least it's detected)...
I read some posts and told myself "I probably have messed up something, let's try it again with a fresh thing"... I clicked on the factory reset button and carried on.
There the phone booted on TWRP (That i didn't know existed before this). As I explored the menus with a TWRP google search on the computer, I began to realize that the factory reset was maybe a bad thing to do with a custom rom. I tried to reboot but I always end up booting on TWRP.
I re-tried to flash in download mode, but with always the "Upgrade stopped due to error".
I also tried to flash directly from TWRP a stock rom. Didn't work.
I was beginning to lose it and tried to flash the CM14 version I had before, juste to have a working phone again, but even this didn't work... I'm stuck with a TWRP phone
I need some help there...

uninstall any drive for g4 from pc and reinstall again and lgup. now reboot phone to download mode when lgup is open first check upgrade opsion and when open kdz check refurbish opsion and start. good luck
Thank you for your answer
Still no luck
Uninstalled drivers
Rebooted PC
Reinstalled the drivers
Still unknown device
The best way to flash stock image is to use official LG Bridge app. Download it, turn off your phone, connect it to PC while holding volume up button - phone will go into download mode. Then there is option for software restore in LG Bridge but i won't tell u where exactly. If it won't work i would try on another PC. If it won't work maybe you would be able to flash stock image trough send_command but i won't help you with it.

open lgup torn off the phone press volume up insert usb cable wait to see download mode on phone release up button and see if everything go fine
Thank you a lot Avantu, the LG Bridge did the trick! I now have a factory rom!
I picked up my UK V30 H930 yesterday all fine and saw that LG have unlocked the bootloader on my model so I went ahead and tried it along with trying the alpha TWRP build
So I thought id write about what went wrong and how I recovered from it.
I made the mistake of letting the phone auto update to 10v software verion before I did this. As I had 10f on before when I bought the phone.
I went to load in all the software needed to unlock the bootloader and proceeded to do so but in my haste of the user data being wiped taking a longer then I thought it would I unpluged the phone to try "fastboot flash unlock unlock.bin" again . No such luck already unlocked. It booted back in fine so I thought everything was ok but that was the moment I thought could have caused my entire night to be ruined.
I thought with the bootloader saying it was unlock it was now fine to flash TWRP on now so went to do that and discovered it would no longer boot into the rom anymore coming up with the LG V30 Logo and just staying put. Thought it must be my 10v software version messing it up. Ok ill try to flash a 10f stock kdz. After about an hour or so of 'Finding my feet' with the phones boot methods for download mode, Fastboot and recovery I found that twrp was being strange with mounting the phone tried otherways eventually got the phone talking to the pc by using uppercut with LGUP and having the phone in download mode and the port com channel in device mananger set to com 41. After about 4 tries of flashing KDZ's to the phone it would just come with a "erasing" circle and proceed to get stuck on boot logo again so I messed about with .dlls and tried to other methods. Still nothing.
Now I tried LG Bridge's "Update error recovery" and I was actually talking to the phone for the 1st time so i let it do its thing which took well over an hour to download the kdz file. "Fine just work please". it got to the updating stage at 5% and froze and the phone being in download mode hadnt done a thing. I tried again but still nothing. Eventually now at 6am and having been up all night I went to give up but I manged to get it on to fastboot mode and by chance came across "flashing lock_bootloader" tried and it and it locked tthe bootloader back up (this thing of LG saying it cannot be undone must be rubbish?) now before I tried anything I rebooted the phone . IT BOOTED! onto the fresh 10v KDZ i had installed on it but before anything I wanted to see if it would now run with a unlocked bootloader on its own with no TWRP installed. It works! Now i just need a method of rooting but im now ready at least.
Hope this helps anyone with simular troubles.
Also had some trouble yesterday after trying out some Magisk modules.
On reboot it sometimes got stuck in the LG V30 screen, and sometimes even the bootanimation came up, but it didnt finish the boot lol
Only installed and adblock btw, and tried the Xposed module. Uninstalled that again btw. Now only using Adblock.
Phone also seems to need Power + Vol- to force shutdown for me, not only Power like other phones. Also didnt manage to find a way to boot into recovery when the phone is off, only found a way to get into the factory reset screen ?
sadly i dont have a working sdcard currently (my 3 year old 128GB one is read only for some reason, atleast changes dont get applied), so ill wait for a new one to mess around more ^^
Also working on a LOS14.1 build atm (it compiled, but didnt adapt all parts of thr device tree yet, and no idea if i have all vendor files lol)

nope, doesnt have one. Neither windows nor Linux fail at writing on it, or when deleting files, but as soon as I re-insert the SDCard all changes are reversed. Formatting doesnt work anymore, unknown error. Tried that in Windows, Linux and in the Phone (Androids formatting crashed, TWRPs produced an error after it timed out)
