Hey guys, today we are here with a trick for a small problem that was faced by any unknown person who visited our website to downgrade his/her LG G4 back to lollipop 5.1.1. We are thankful to him for sharing his problem with us and for him and other LG G4 users we are here to fix an error after downgrading the phone. The unknown user told us that he is finding an error on rebootin his phone and the error was "Current version is not available for user. Can't find matched cust for NT-Code MCC/MNC[FFFFFF],SUBSET[56]".
So guys if you are having any this type of error like above on rebooting then don’t be feared about that as all these errors comes because the firmware are made different for different countries and you are probably using an international firmware. It’s a simple trick to correct the error and I know that error annoyed you a lot but from now you are going to be free from this error.
Note :- According to your firmware you could see any error of the type above but the error is same if it appers like "Current version is not available for user. Can't find matched cust for NT-code MCC/MNC[XXXXXX],SUBSET[XX]",i.e., there could be anything instead of ‘X’.
Let’s begin the trick :)
Requirements :
* Root Access in your LG device.
* ES File Explorer App
Steps to fix the error :
* Open ES File Explorer app.
* Go to the “root” folder of your device.
* Search and go to the "Cust" folder.
* Open the "cust_path_mapping.cfg" file with “ES Text Editor”.
* At the top(or bottom), give a space to add a new line.
* Type the following : XXXXXX,XX=/cust/OPEN_IL. ( Replace the characters of your own like for the unknown user the characters are “FFFFFF,56=/cust/OPEN_IL”).
* Now, save the file.
Note :- You may be asked to enable Read-Write capabilities, so allow the ES File Explorer to do so.
* Now reboot your phone and get rid of that annoying error.
Remember :- As I told you firmware is different for different countries, so in case if your are using a European device, and the above edited character does not work, then just replace "OPEN_IL" with "OPEN_EU" and for US devices replace with “OPEN_US” and so on. One mor thing I want to tell LG users that LG G3 users can also use same process to fix this error.
That’s it guys enjoy with your phone and be connected with us and give your precious comments to us :)
HI, I'm an G4 and a G3 user and i have this problem with the G4,
ReplyDeleteit started when i got a backup battery, used it for couple of hours.
then the phone went into bootloop and couldnt get it to work ever since.
I gave it to a repair center, they tried to fix it but couldn't. when they gave it back, i tried couple of times and then the phone switched on and i got that error message,
I'm able to use the phone for maybe 2 minutes and then the phone switches off and tries to boot, but remaining in the gray screen(black screen).
I gave the phone to the LG company for repairs and they said they have to replace the motherboard( which i think they dont know how to fix it so they want to do that).
The motherboard itself costs like 70% of a new G4 so I didnt want to do so.
My question is what may have caused this? Because it all happenedi tried replacing batteries and started. how can i get my phone to install es file explorer and work with it in download mode if the phone it self wont switch on properly? I can try to install the file explorer during those rare times where the phone will switch on,
But like i said the phone will be usable for 2 or 3 minutes,
I can send you guys some screenshots and maybe a short video i took.
Thank You for your help in advance
(sorry for my bad english)
I apologize, I forgot to add few things,
DeleteWhen the phone is completly shut off, And when i plug the charger, the phone tries to boot up instead of charging it without booting (showing the battery icon and percentage)
And if i try to leave it like that for few minutes the phone and battery heats up.
I tried to do a hard reset (holding power+volume key thing) sometimes it will go maybe half way and the phone will freeze, or as i select the hard reset option the phone will freeze and back to the black screen.
Thank you very much you're a genious
ReplyDeleteDoes this method work with any Android powered LG smartphone? I tried to do it with my LG Leon H340Y and it didn't work, even though I followed each and every step.
