How to Root LG v10 H901 Android 7.0 Nougat

In this post i am going to write about How to Root LG v10 H901 Android 7.0 Nougat, But before start root process for LG v10 you must have bootloader unlocked on your LG v10. So if you are confused or don’t know how to unlock bootloader on LG phones you should first reed How to unlock Bootloader on LG v10 artical. If you deviate from this procedure, and think: “I can just skip a step, or I can do this on my own Linux install”. Don’t complain if you brick your phone.

PREREQUISITES:

  • You need to download FWUL (version 2.7 or later) and burn it to a USB stick: link
    Even if you have Linux, and you think you can install the dependencies, don’t. I know this works from FWUL.

PROCEDURE PART 1: Installing TWRP

  • Boot from your FWUL USB stick. If your PC has secureboot enabled, you will have to disable it in BIOS
  • Put your phone into download mode. By turning it off, hold vol up and plug in the USB cable. You do not need to touch the power button — the phone will power on and enter download mode.
  • Once booted successfully to FWUL, Login to FWUL. The password is: linux
  • Double click the LG folder can be found on the desktop
  • Double click on LG LAF (runningnak3d) icon and you will be at a terminal prompt.
    Execute the following commands in terminal one by one. You can copy / paste them if you like.
Code:
git pull
git checkout v10-miscwrte
./step1.sh

When you are told to, pull the USB cable, and the phone will power off. You have TWRP installed now. At this point you can flash a ROM, or Magisk or whatever you like using TWRP.

OPTIONAL:
If you don’t know what to do with TWRP, and you just want to run rooted stock, this is for you….
First boot into TWRP – with the phone off, hold vol down and power at the same time. The second the LG logo appears, release power for a split second, then then press and hold power again (you never let go of vol down).
When you get a screen asking you to factory reset, you can let go of both buttons. hit vol down to select yes — two times — this will take you to TWRP.

PROCEDURE PART 2: Rooting and cleanup

Now when you are in TWRP enter command below via terminal:

Code:
./step2.sh

If you ran step2.sh you have TWRP on recovery, and you are rooted. If you only ran step1.sh, then you have TWRP on recovery. Either way, enjoy! Subscribe via Email and Social Media for more.

LG G5 Restarting After LG Logo Fix

If your Smartphone failed to boot normally and stuck or restarting on boot logo, This failure called boot loop. In this post i will try to show some steps to clear boot loop problem in your LG smartphone or any other brand. To fix boot loop problem in your LG smartphone you need to follow these steps. I suggest you to read whole post before starting. Please keep in mind do all at your own risk, i ma not responsible for and damage.

Steps:
1. Loose Battery connection
2. Software Customization
3. Faulty Battery ?
4. Poor Hardware

1- Loose Battery connection:

If your cellphone is being restarted at startup logo or shutting down automatically in your pocket you should first check battery connectors both cellphone’s and battery side.

Because of dust or due to touching battery ? on tongue ? by mistake. Some people thinks that they can test battery current by touching it on their tongue ?. But they don’t know they are actually destroying battery and terminals. So it should be a first reason of boot loop problem.

Solution!
Clean terminals on both battery and cellphone side.

2- Software Customization:

If have done any customization in you cellphone software like root, custom recovery, custom rom and your cellphone is now stuck on startup logo or being restarted after logo, This called boot loop due to software customization.

This problem can only be recovered via loading correct software (Official firmware), please never ever try to play with you cellphone board. There is no hardware fix if you have bricked your phone due to root, flashing custom recovery or custom rom. Just flash official firmware for this type of problem. visit How To Flash/Upgrade LG Android Phones With LG Flash Tool to know more about official firmware flashing method and How To Download LG Firmware By IMEI?

3- Faulty Battery:

In my experience as a cellphone technician, I have seen and fixed lots of smartphones with restarting  problem at boot logo by replacing or modify cellphone battery.

Why Mostly Smartphones Restarting on Faulty Battery?
Almost all smartphone batteries comes with self protection circuit. Some manufacturers using a resistor in series at GND line to protect battery from short circuit, over load etc. some times this resistor loose it’s resistance due to over heating. Then this resistor will not pass enough current to the phone, and phone starts rebooting on startup logo.

How to Restart Fault is due to battery?
In my experience we noticed that mostly phone stop rebooting while connected to charger. So if your cellphone is working fine during connected charger, and start rebooting immediately or in few seconds when charger being disconnected. It must be due to faulty battery or loose battery connections.

Solution!
Change your cellphone battery and you’ve done! If can’t change battery with new one then you can fix this problem by shorting big resistor used in series at GND line. Watch this video to understand.

4- Poor Hardware:

This is true that mostly LG phone users facing boot loop problem due poor hardware parts and logic board assembly by manufacturer. Boot loop problem is become famous from LG G3 series phones and later models.

Solution:

Follow the video to fix boot loop on your LG G5 or any other smartphone, But be very careful if your phone locked using black glue under CPU.

LG G4 Bootloop Fix

In this video i have described all information about LG bootloop, I have fixed so many LG phones with bootloop problem. So i have made this video for people who facing bootloop problem in LG phones specially in LG G4. This video is about poor LG batteries quality. Lg and some other Smartphones have poor battery circuits in side battery and that is the reason of mostly phone restart after showing LG logo. I have seen 55% LG bootloop problem comes from battery.

How to conform that bootloop problem is due to battery?

If you noticed that LG phone restarting after showing LG logo and working good when charger is connected. mean when we connect charger to phone and then power on phone booting normally. and when we disconnect charger phone start restarting again.

Why bootloop comes in mostly LG Mobile phones?

Because of poor quality batteries and hardware. but in this video i have described about bootloop fix via battery. In LG Smartphone batteries manufacture used and 0 ohm resistor for protection and overload. in most cases this resister gone weak and increased it’s resistance. and when this resistor increase it’s resistance then battery can provide full current to phone phone. and phone start bootloop when battery not provide enough power to phone. that is the reason of bootloop due to low battery current.

Follow on Google+ for more useful information about Smartphones.
