I bought this LG E980 AT&T model (v20G) and I installed E988 stock 4.4.2 OTA ROM (.kdz method) given by sandyiscool in this thread
http://forum.xda-developers.com/showthread.php?t=2754294
it was successfully installed until i realized there's alot of modem problems i.e. my 3G would show up but would run very slow as compared to other phones using same carrier.
So now I wanted to revert back to Stock ROM E980 (.tot method), but as soon as i put my phone in download mode and plugged into the PC, LGFLashTool gave me the error "Bin model is different" and then got red and failed to install Stock ROM. I think the download mode model has been changed to E988 while i was installing its OTA Rom.
Is there any way to revert this download mode back to E980 model. I tried both E988 and E980 .dll files for .tot flashing tool but both gave same error. I can only find E980 TOT files and cant find E980 AT&T v20g .kdz file anywhere (I think that may solve my problem if i find it). Please provide a solution to let me revert back to E980 OTA rom. I'd be really thankful.
Hi all, just unrooted and took an Ota from 10g on my att lgg4. I was expecting to be on i, but I guess a new update was released that I didn't know about. Can I still root this with the normal method and if so does anyone have a rooted system image available to download?
Hi,
I purchased the phone in the UK from the network carrier Vodafone. I have done a fair bit of research on the rooting and unrooting process mainly via videos and reading tutorials on XDA.
I would like to root the phone and gain super user access and install some Xposed modules but would also like to be able to unroot and flash back to a stock Vodafone firmware encase I need to claim under warranty. I have been trolling the internet to get the correct KDZ file and found this site (ttp://devtester.ro/projects/lg-firmwares/country.php?country=United+Kingdom). I believe that the correct firmware may be on here but am a little confused on what the suffix and software version means to be honest.
The reason for my confusion is that I updated the firmware to 6.0 Marshmallow through the LG bridge but when I now check my phones software version it states v20b-234-15. I assume this is right but from memory the first software version when I got the phone was something like H81510B_00.
I cant remember exactly what it was before unfortunately but the KDZ files I have found state H81510C_00 (Suffix - AVDFVK) and H81510C_00 (AVDFLR) and this does seem to make sense but I'm thinking it was B instead of C but and not 100% on that.
Do you think these KDZ files would be the correct one to flash back to encase I run in to some problems rooting?
I am also assuming that this KDZ is Android Lollipop and not Marshmallow so is it OK to use this to revert back from Marshmallow?
Thanks and any help would be much appreciated.

The 10X version are all Lollipop, 20X is marshmallow.
When flashing a KDZ on your phone, what's important is what model your phone is. H815 in your case.
If you want to restore to stock in case something goes wrong, you can find everything here: http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
In there is a link to this directory: http://storagecow.eu/index.php?dir=Xda/LG+G4/ where you find pretty much all KDZ files for G4 phones.
I'm not that experienced myself, but I rooted my phone just recently and I can share my experience with you.
I have a H815. It was a V10c-TWN-XX version (Taiwan). I updated to Marshmallow with LG Bridge also and the new software version was V20b-TWN-XX.
Marshmallow rooting is not possible on my phone because I can't unlock the bootloader on it. And Marshmallow rooting is only possible with an unlocked bootloader. Unlocking the bootloader is only possible on European phones (http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS). I asked autoprime (renown user and developer here) if I can unlock bootloader after flashing an European KDZ on it. He said no, having European software on it is not enough, it has to be a phone manufactured for the european market. Dont know why, guess because of different hardware.
So, not being able to root MM, I had to revert back to stock (downgrade) using one of the KDZs.
I chose the most recent one in the directory I linked (which is the Poland H81510E). In the "Go Back to Stock" thread I linked the OP says to use LG Flash Tool 2014, which unfortunately doesn't work with Marshmallow. But fret not, it works with LG UP! http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
When I tried flashing the KDZ with Flash Tool 2014, the process failed with an error at 5%. It worked flawlessly with LG UP. Here's more information regarding downgrading, but it really isnt hard. Just download + install LG UP. Launch it. Connect your phone. Choose KDZ file. Select option "upgrade". Hit start.
NOTE: after the firmware update was done, the phone rebooted automatically and for me it stuck at at the LG Logo (bootloop). But a simple hard factory reset did it, the phone booted and my new version was 10e-something. With Lollipop 5.1 of course.
After that, I rooted my phone using this pre-rooted image: http://forum.xda-developers.com/g4/development/h815-eu-l-p-t-sea-twn-t3176195
and this guide: http://forum.xda-developers.com/g4/...-tmo-vzw-intl-variants-soon-root-lg-t3164765/
I now have a "H81510e-EUR-XX" Lollipop 5.1 with root (SuperSU 2.49).
I don't really know about Vodafone and if carrier specific firmware is necessary in this case. If not, you could use any 815 firmware.
From the site you have linked with the KDZ files..... it seems they are all the same.
If you check the table for H815 KDZs from Vodafone, there are some 10C and 10D versions. Now I compared the fileKey parameter in the URL to the 10C files and the 10D files and also the bytes of the files.
All the 10C version are identical to each other, same for 10D.
Check out this screenshot I made for you: http://i.imgur.com/Ie0w4us.png
Bytes are also identical, so it's pretty safe to say those are the same files.
Dont know why they are listed several times there. The suffix doesnt matter.
I'd grab a 10D if I were you. But I think the Poland 10E should work, too. Better confirm it with somebody else though.
If you flash your system to 10e, you can use the pre-rooted image I used. Otherwise you will have to inject root yourself: http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586. In this method you create an image of your system and inject root into the image, which you then flash back on your phone.
In my country G3 still didn't receive the update to 6.0 OTA. I'll probably just upgrade it manually since i am tired of waiting.
If i manually update my D855 to 6.0 it will be able to receive 6.0.1 or others upgrades OTA in the future? The manual upgrade to 6.0 done by the LG flash tool is official?
Thanks in advance

If you flash kdz made for your phone you will recieve ota otherwise you won't. For receiving ota you have to flash kdz file made for your for your country's g3.
I strongly reccomend you to follow this thread to prevent hard brick: http://forum.xda-developers.com/showpost.php?p=64624353&postcount=3
Using the LG Flash Tool instead of the newer LGUP may cause serious troubles when flashing Marshmallow kdz files.
I have a d852 on mm and want to downgrade to lollipop, my big question is I have found the tutorial for it but it says to download the KDZ file but when I look there is only a Telus one for Lollipop. I just wanted to know if I can safely flash the Telus on my Fido phone
Thank You
