"For quite a while you are using your LG G2 mini. You like the simplicity of Android 4.4/5.0.2 and you think LG did a good job on the UI. You live you life happily with the phone. But after a while you feel something is missing. you want more.
You googled "How to make my device awesome again" and you saw difficult terms, such as root, flashing, recovery and bootloader. You didn't know what they meant, but you knew you have to understand these terms and apply them to make your phone awesome again."
The steps to make your phone awesome again are fairly simple:
perform these steps in order from top to bottom. Do not skip any.
--Rooting--
"Yes... I remember seeing this term.. I vaguely remember something related to permissions.. but I am not totally sure what this means."
Root - The root directory of your phone. The home directory for all your important system files.
Rooting - Normally, you don't have access to this directory, since the manufacturer doesn't want you to mess with it. Rooting means you will give yourself access to this directory. Why do you want access to this directory? Because later on we will need access to it to change some files.
Most common question asked is: will this void my warranty? YES
How to Gain Root Access
Android 4.4
There are a few methods to try. If one fails, you will continue until you succeed.
Method 1
1. Go to this link
2. Click on the big lambda in the middle of the page ( ? )
3. Install the app on your phone
4. Run the app and tap on "make it rain"
5. Your phone will reboot
6. Download SuperSU from here. This app is a root access management tool, and it allows you to give certain apps root permissions.
7. The app might ask you to "update binaries". If so, let it update.
Optional: Install this app to make sure you have root access.
Method 2
Go to this link and follow the instructions.
Android 5.0.1
There is only one method for rooting on this version.
Method 1
1. Go to this link and follow the instructions
--Unlock Bootloader--
"Bootloader.... is that a machine that loads boots?"
Bootloader - Code that is executed before any Operating System starts to run. A bootloader is usually locked on an Android device because although it’s an open source OS, still the manufacturers want you to stick to their Android OS version specifically designed for the device. In order to apply this concept, manufacturers lock the bootloader. With a locked bootloader on Android devices, it is virtually impossible to flash a Custom ROM.
Most common question asked is: why do I need to unlock my bootloader? Unlocking the bootloader allows you to install custom Firmware on your Android phone.
How to Unlock the Bootloader
It is advised to be on Android 5.0.2 to unlock bootloader.
Android 4.4
There Is only one specific guide for the d620 / d620r models.

Android 5.0.2

--Custom recovery--
"After reading so much I think I need to be recovered myself!"
Recovery - Software that can be used to restore the device to factory default settings, update its operating system, and perform other diagnostic tasks. A custom recovery is a third-party recovery environment. Flashing this recovery environment onto your device replaces the default, stock recovery environment with a third-party, customized recovery environment. A custom recovery environment will do the same things as the stock Android recovery. However, it will also have additional features. Custom recoveries often have the ability to create and restore device backups.
TWRP - Team Work Recovery Project is the most common custom recovery out there. It is highly advised to use it, since other recoveries made for this device are old and unstable.
Most common question asked is: why would I want to use a custom recovery? Custom recoveries allow you to install custom software such as ROMs and kernels.
How to Flash a Custom Recovery
1. If you already have a custom recovery, enter it and flash the new recovery zip.
2. If not, download and install THIS app and flash though it the recovery zip. Then you'll be able to enter the custom recovery.
All Android Versions
There are several versions of TWRP. It is recommended to use the latest version, though using an older version won't hurt.
1. Go to HERE for Twrp 3.0.2.0
2. Go to HERE for TWRP 2.8.7.0
--Custom Rom--
"That was it? It was so easy!"
Rom - stands for “read-only memory.” A custom ROM replaces your device’s Android operating system — normally stored in read-only memory — with a new version of the Android operating system. Custom roms usually have added features not available in stock Android.
Most common question asked is: why would I want to use a custom ROM? Read THIS article.
I'm sorry for any left out roms. A lot are old and not updated or contain bugs. An updated list of them can be found at all time in the "Android Development" section.
How to Flash a Custom Rom
1. Download a custom rom to your sd-card.
2. Enter twrp recovery.
3. Make a backup of system, data, boot and cache.
4. Flash the custom rom.
5. Optional: flash Gapps.
6. Reboot to system.

--Custom Kernel--
"I'm going deeper... so deep, I'm almost at the kernel!"
Kernel - The kernel is the piece of software that bridges the gap between the operating system (and installed apps) and the hardware in the device. Everything you do on your device involves the kernel. Increasing the volume while playing a video? Android doesn’t directly tell the speakers to increase output. Instead, it tells the kernel that it wants to increase the volume, and the kernel talks to the speaker to increase its output.
Most common question asked is: why would I want to use a custom KERNEL? Read THIS article.
How to Flash a Custom Kernel
1. Download a custom kernel to your sd-card.
2. Enter twrp recovery.
3. Make a backup of BOOT
4. Flash the custom kernel
5. Reboot to system.

Please do not quote the whole post.
The LG G2 mini Tegra edition is very different from the other varients. It has a different board and uses other components. Unfortunately, to this day there is no way of unlocking it's bootloader, but even if it could be unlocked, there is no rom development for it. I don't know about rooting it, but from my knowledge, there wasn't ever a serious discussion about rooting it. The main reason is this phone is mostly seen in Latin America, while the rest of the world uses the "normal" version of the phone.

Hi guys, I need some help! I'm stuck with the custom recovery. I'm on d3620r20b, rooting and unlocking bootloader worked fine, even flashing recovery.img using rashr works fine, but if I reboot into recovery mode the phone just gets stuck at the LG logo..Any ideas?what could have gone wrong?
Thank You!

Hi,
I have a LG G2 Mini D620 which is still on KitKat 4.4.2. It never got an OTA update to Lollipop.
It has:
Baseband version: MPSS.DI.2.0.1.c8-00012-M8926DAAAANAZM-1
Build Number: KOT49I.A1404447153
Software version: V10g-EUR-XX
It is rooted.
What I would like to do is upgrade it to at least lollipop. Stock lollipop is fine (custom rom is not a must).
Can you point me in the right direction as to what would be the best way to achieve this?
Regards.
You can find the version you want http://lg-phone-firmware.com/mobile/ and flash it to your phone

I tried different recoveries with different softwares but I always got the same problem.
I solved downgrading to kitkat and following the 4.4 method. I guess something was not working in the rooting procedure..
Hi guys, I have an D620k which is on KitKat. I want to update to Lollipop trough KDZ.
Do I need to download the 620k version? Or I can flash anyone that is for 620?

... sorry but I'm very confused ...
I'm reading the possible on the network, but the result is I always get confused more despite having a certain familiarity in modding having modded a galaxy nexus, and an LG G2 on which I installed TWRP recovery and various CyanogenMod ROMs.
Unlocking the bootloader in kate/SE, in an official or unofficial way, is still very difficult or almost impossible?
I often read of modified TWRP recovery, which sometimes give problems and sometimes it does not ...is it possible just put the official TWRP for kenzo?
If I can somehow install a TWRP, is possible to easily install the CyanogenMod ROM (after flashing ROM flashing kate modem is needed) and provide CM updates simply by flash new ROM via TWRP recovery?
Thks in adv
Nope! It's easy as 123... Please, check:
http://en.miui.com/thread-345728-1-1.html - for unlocked "emmc_appsboot.mbn".
You can also download ALKA TWRP, rename to "recovery.img", and replace it in fastboot ROM (image folder).
(As well as "emmc_appsboot.mbn emmc_appsboot.mbn", downloaded from the link above.)

I could not unlock my "kate" officially.
I've tried the method posted above, and works like a charm!
No bootloop, at all...
Thaknk yo so much for yr reply
I remain with the feeling of more complexity and less certainty, than the modding of the galaxy nexus and also the LG G2...
Official unlock works fine.
I have a Kate and unlocked it officially.
Just make sure to flash the global developer ROM, log into your MI account on the phone and press the "bind device to account" button inside the security settings menu before attempting to unlock.
I also got my Kate to unlock officially after using updater on phone to flash global beta rom.then in developer options clicked MI unlock status then linked phone to account. After that unlocked first try after many many failed attempts on global stable.
Nice news and info, thks so much!
But... why so many people can't officially unlock their kate having 50pc error...??
Which version of miui unlock tool and Global Dev. ROM you used when officially unlock yr kate?
I used global beta 6.11.24 and MIflash unlock_1.1.1111.1_en
Thks for reply and info
I have an app that does not work after Android 8 that I need and there is no replacement in 9 or above. I managed to avoid updating my v30 to v9 and later for a year or so. It accidentally allowed the update to 9 this past weekend while I was camping. All I want to do is roll back to stock v8 or 8.1 (Oreo).
I have enough tech knowledge to follow directions and understand rooting but am having a really hard time finding the "right directions." As I was reading some of them, I found caveats like, "Use X unless you have the delta update and then use Y but not if you want to run Z. For Z, you have to follow this other thread." I also know that using the wrong settings or data file could brick the phone.
So, I'm hoping someone can help me narrow down what sets of directions I need to follow.
Here's what I have right now:
LG V30 (VS996) On Verizon Network
Developer Options Enabled
Android V9
Security Patch Level August 1, 2019
Kernel Version: 4.4.153
Build #: PKQ1.190414.001
Software version: VS99630c
Again, all I want to do is roll back to stock v8 or 8.1 (Oreo).
Bonus would also be a way to stop asking me every day to update or delay a day and just wait until I manually do it.
Thx in advance!!
Download the right firmware file for your device from here -
Models - LG-Firmwares.com
Free archive of LG firmwares. Comparison of features and reviews of all mobile devices. Quick download of updates for your device.
lg-firmwares.com
Then download the flash tool from here -
LG Flash Tool Free Download - Official Download Links
LGUP tool is the latest version of LG Flash Tool that allows users to flash stock firmware on LG smartphones and tablet devices. Download LG UP tool 2018 from the official download links.
lgflash.com
Follow the instructions on both the pages. I think you can take it from here.
Note that implied with this process is that you cannot downgrade your firmware without wiping the phone... there's no way to "patch" back to the old version. So, be sure to take backups FIRST.
If you're rooted on the old firmware, you can then disable/freeze/delete the update APKs so that the update warning goes away. But this requires root, so be aware of that. If you don't haven't rooted already, then this is a process of its own, and will require you to go back to Nougat in order to perform that, so you may want to do that before installing the final version of the ROM you want. You can find out how to do this rooting process on the WTF thread, post #193, located here: https://forum.xda-developers.com/t/...ar-instructions.3790500/page-10#post-76584629
If you don't want to root, that's fine, but then you must endure the update warning process... unless you can find another way to disable the update APKs.
Thank you both. I expected to wipe the phone so that's not an issue. I will first install Nougat, root and then update to Oreo.
There are about 14 Oreo ROMs on that site. Do I just pick the latest one or do I have to pick the earliest one and update that?
Pick the latest one.
