Can yall help me how to downgrade from N30g to N30d? im quite scarred because some of the korean firmwares are at 800mb and the rest are over 3gb
use lgup dual first in refurbish mode and then partition dl and select all to downgrade there will be no error.

I just upgraded LG-D850 (AT&T) from Kitkat 4.4.4 ver to Lollipop V20A, kdz file using lg flash tool (downloaded from lg-phone-firmware site)
After upgrade, it asking me for Enter PIN/Password to decrypt 30/30 attempts remaining
and it also shows popup which says current version is not available for user can't find matched cust fot nt-code mcc/mnc[310410], subset[ff]
I dont know what does it means and how to solve this issue ?

Looks like a few people have this issue, can you get into recovery? To remove the encryption you will need to reset your device as their is no working way to decrypt the phone and keep data as far as i am aware, except for bruit forcing it

I know it's strange but where you found kdz file for LG G3 d850 (att). As far as i know and heard there is only tot file available for that, You might have flashed the kdz file of some other variant, so it is asking for key. You better roll-back to kitkat by tot method,

Then root and install TWRP. After that you can flash stock lollipop (20f) zip file to get official stock rom.

long time lurker here.I bought a g4 second hand.it was advertised as h815 unlocked.the imei checked out online and all stickers said 815 as well.but in hardware info it showed h815T(HK variant).thankfully i knew how to flash firmwares so i downloaded a KDZ and flashed it with lg ft 2014.for some reason (i dont remember why) i flashed 2-3 times with other kdzs and ended up in the current state.the phone now shows H818(dual sim variant) in hardware info and doesnt
detect my sim card(same sim works fine in my G2).I never downloaded the h818 kdz.
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||((TLDR))||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
phone shows wrong model in settings and doesnt detect sim card.flashing stock kdz doesnt fix this
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

i think is was misinterpreted. its a h815 but a h815t indeed and unlocked mean carrier as you know theres no way to unlock bootloader.. you need to flash the h815T KDZ. i hope that you didnt mess your imei.
inject only works in LP not on MM. also youll need to find out if you can downgrade to lollipop. as this phone have antirollback wich means once you are on a version you cannot go nack or youll hard brick phone.

thank you for the response.im on lollipop right now since ft 2014 doesnt flash MM and lgup and ft 2.0.1.6 stop flashing after checking phone info(they stop flashing as phone shows h818 but kdz is for h815).I flashed h815T kdz multiple times(twice just today)but phone still shows h818 in lgup and in settings.the phone cant be h818 as it only has 1 sim slot.
imei is ok right now.SIM issue happened to be a ****ty sim cut job by the customer service guy.only remaining issue is the wrong version showing up in phone settings. cant flash MM due to that.
also,is there anything good about upgrading to MM???

Actually MM isnt an upgrade. Lollipop is best(maybe nougat will be worth anything). I think you should flash uk v20g kdz with lg up(or LG firware flash 2014). I suggest using LG UP also you can give TOT method a try

Do they check in build.prop? If so just change build.prop value and you're good to go. I think that there is also possibility to fake your software version and then flash anything you want

can anyone help me find a lollipop kdz for my g4.it was advertised as an h815 but the board says f500l.i have found MM kdz but cant flash them as flash tool 2014 doesnt support marshmallow and lgup checks phone version before flashing (mine shows h819 for some reason??).also,is there a way to convert tot files to kdz??
hello everyone ,
i got LG G4 H815L
now i was on Android 6.0 a long time and i see that i able to upgrade to android 7.0 with LG UP and TOT file for my model
so i did this .. and the android 7 boot up and everything was fine but all my things and the carrier bootup logo stay ..
so i think that i should take the TOT file again and press refurbish and not Upgrade button
here is the problem .. i am stupid
so the flash failed on LG UP and the phone get stuck on Firmware update
and .. i cant do anything else ... i try to flash a lot of versions of android 6 that fit to my model H815L
but they stuck in LG UP on 24% and after that i get Error message 0x2000
i try to search about 4 hours how i solve the error ...
i replace 8994 dll's
try to install LG drivers again
and lg up again from another source
and really everything
so i give up ... i need a help ..
in the LG up software i see in version H81529A
maybe my phone think that he another model ?
but the TOT file that i download of android 7 is optimized for H815L only ..
Update :
LG UP let me Flash H815 V20P
on my H815L
but i didnt have my language on my phone...
what did i do.. i didnt want to flash again KDZ file on LG up and make my phone brick again ...
why i cant flash H815L ?
i add the language that i need with moreLocale2
but every reboot the language deleted ..and its annoying
i want to flash H815L
from my country but its not possable
all the KDZ files didnt reach 100% in LG UP
and brick my phone .
Help someone ?
Hi.All.I have cross flashed LG v40 Hong Kong version Rom Android 9 with the Korean Android 10 using lgup.
THE Rom was installed but I lost radio.no signal. So then on the advice of a friend I flashed partition dl modem a and modem from a eu version android 9 .and when the phone rebooted it shows security warnings and says all slots are unbeatable. Any way to put ut in download mode so lgup can identify.Any easy way out.thx

You need laf_a and laf_b partitions from HK 20a firmware
Then partitionDL 20a kdz
Then refurbish 20a kdz again to restore cellular.
Is there a way to identify region of LG V405EBW?
I did flashed both EU and HK KDZ but still no signal. I totally forgot to backup my firmware and now my phone has no signal
Come to lg v40 telegram forum to help. You
