How to Unbrick LG G4-H811 Using the Loader Method, SD Card

This second method to unbrick G4-H811 employs the use of G4-H811 ROM Dump also known as full blk0 backup file.
This file, saved as G4-H811 Loader.img file can be flashed on an SD Card and used to revive your hard bricked G4-H811.


The Does and Does Not of this Method
The Does The Does Not
With the correct G4-H811 Loader.img file, you will be able to access your G4-H811 recovery partition again. The G4-H811 Loader.img file ONLY boots your device to bootloader / recovery mode and not the OS.
This method aid your G4-H811 unbrick solutions. It's not the do-it-all. This G4-H811 Loader.img file will not boot your device to OS. You need full firmware to do that.
This Loader.img file only loads Motorolla Stock Recovery partition on your device. This Loader.img file does not currently load custom recovery such as TWRP on your G4-H811 therefore, only Stock Firmware can be restored to using the method described here.
The SD Card (used) helps boot the device into receovery mode ONLY. You cannot use the same SD Card with the device except you format it. You can use Mini Tool to Partition or format the SD Card for re-use.

Troubleshoot! Having Issues Using this Method? See Below:
Issue(s) Solution(s)
RSDLite, Motorola Device Manager successfully restored my device but my G4-H811 still boots to recovery. What can I do? Before you boot up the phone or while the phone boots up, make sure you remove the SD Card from the phone.
The PC no longer see my G4-H811 in Qualcomm HS-USB QDLoader mode. What's wrong? Until the SD Card is in your phone, PC will continue to seeing the phone as functioning properly but only with flat battery.
My G4-H811 is stuck at boot logo instead of booting to recovery. What can I do? Try another SD Card. You must use a first class (Class 10) grade one SD Card that's really fast.
My G4-H811 is in recovery mode but Motorola Device Manager / RSDLite does not detect it. Is something wrong? Yes. Something is wrong. Check your USB Cord, USB Port or make sure that your drivers are properly installed. With each instance, you can try with another device to confirm.
Have other questions? Good! Drop your comment. I shall attend the question(s) and also include it in the list table.

How to Create Bootable SD Card with G4-H811 Loader.img File On your PC

1. First, format your SD Card. exFAT is preferred.
2. Download and extract DiskImageRev2 onto a folder on your PC then, open it. Download DiskImageRev2 from here.
3. Slot your SD Card in a card reader and connect it to your PC.
4. Launch DiskImageRev2 on your PC - as Admin preferrably.
5. On launch, DiskImageRev2 should detect and display the drive where your SD Card is connected. If otherwise, browse to select the drive.
6. From DiskImageRev2, browse to the folder where you saved / copied the G4-H811 Loader.img file on your PC and select it.
7. Now, click Write and wait until DiskImageRev2 completes the process.

    Once DiskImageRev2 has successfully written the files on the SD Card, your SD Card is now bootable! You may now insert it on your G4-H811 and boot the device using its bootloader key combo.

The Loader method requires a full ROM Dump also known as a full blk0 backup of a working G4-H811 correctly/rightly flashed or written on a pretty good and fast class 10 SD Card.

The logic behind this method is that, as already demonstrated on Moto Z Play, most Qualcomm devices can boot from SD Card formatted using the right system files written in the right order.

We will therefore attempt to extract G4-H811 loader.bin or loader.img file and flash it on an SD Card so that, when slotted on a G4-H811, the device could identify it as the eMMC and boot from there.


This method only takes your device to recovery or fastboot mode wherein you can use official software programs to flash the device.
