Root I need to root lg k420n

hussein khalil · Mar 1, 2020

Hello guys,
please i need your help rooting my lg k420n device. There are very very very important photos on it, and my little brother "factory reset" the device without a backup. Please guys is there any way to root it?? i tried tens of ways, one click root apps (both pc & phone version), i tried to root it manually but i faced a lot of problem especially that when i go into fastboot mode the command "fastboot devices" cannot recognize my device (i tried to install mobile drivers and didn't work) i tried a lot of tools but without any positive result. so please guys can you help root my device to reset my photos using diskdigger? or there is any good recovery application that doesn't require root?!.

Were you using Google photos?

unfortunately NO

Then I'm afraid they are all gone with no amount of rooting will ever bring them back.

yep rooting will not help your situation. and those data recovery programs that you pay for, i believe are scams (at least most of them are). i have yet to hear anybody having success with those. so be careful if you do go that route.

i use google photo's and you can set it to automatically backup your photos. i never have to worry about them accidentally getting deleted. i can take a picture, wait for my phone to sync and hop on my computer without connecting to my phone to get the photo i just took.

if you still want to try to root the phone, we can try and help you. but it will not bring your photos back.

Back, when i lost my photos (in the same situation “factory reset”) i rooted my Samsung grand device and restored all the deleted photos with diskdigger!! It worked perfectly.

ok first off i do not have your phone.
second i would try and follow this guide:
https://forum.xda-developers.com/lg-k10/how-to/bootloader-unlocked-guys-bootloader-t3558810

it is a bit complicated, so please read it carefully. if you have the time i would read all 18 pages of posts within the guide. there are some good questions in there that might help you as well.

and ask questions if you have any here.

no.....that guide is how to unlock the bootloader to gain root. here is the break down:
1.downgrade your firmware using LG UP
2.then use KingoRoot to root the device
3.then use your computer to adb command the specified aboot to the phone.
4.reboot

and you have an unlocked bootloader. to stay permanently rooted you will then need to flash a recovery
(TWRP) and flash superuser to finally gain root.

Even if you root, you still may not be able to recover any photos.

the op claims that diskdigger will work......i'll guess we will find out....that is if he can get his phone rooted.

ocnbrze · Mar 1, 2020

well doing some research. this article claims that disk digger pro will also work on unrooted phones, but recoomends that it works better on rooted phones.
