About this LG G4 Hardbrick Issues

To some people, it seems impossible to unbrick a hardbricked LG G4 that is hardbricked without using JTAG but that is not entirely true. With access to the right set of files, tools accompanied with well laid-out tutorials, you can actually unbrick the device without having to disassemble the phone.
Another thing you may not know is that, JTAG requires an extremely prefossional touch. A device that failed with JTAG (as a result of any errors at all) has no option of recovery left hence, JTAG should be considered only when you are ready to give up the phone.

When Should I Consider My LG G4 Hardbricked?

Your LG G4 may be considered hardbricked when;

  1. It does not power-on
  2. Powers on but displays blank screen
  3. Only viberates when the power button is pressed
  4. Shows either QHS-USB QDLoader 9008, QHUSB_BULK, QHUSB_BULK PID_9008 (in Windows device manager) when connected to the PC

About this LG G4 Hardbrick Fixes

Late in the year 2016, one of our facebook fan page followers (name preferred not to mention as instructed) who was having a hardbricked LG G4 asked if we can help provide the device unbrick files in exchange for some token.
As you may have known, back then, the LG G4 was worth a handsome sum so we decided to help and that was what gave birth to these solutions.
Although, we were granting access to the device unbrick files following a subscription (which used to cost around $17 USD) lots of people subscribed and enjoyed the value for what they paid, so did we.

Some LG G4 Devices Not Repairable By these Solutions Are:

  1. Those that become dead due to high voltage (passage)
  2. Devices with broken/spoilt external storage slot
  3. LG G4 devices that are having spoilt USB port
  4. Please be sure your device screen is still okay (displays fine)
  5. Ensure your battery is still okay and can retain charges

  • Make sure your phone's battery is at the least 80% charged before you begin the process
  • Make sure you have a consistent or reliable power supply (for your PC) throughout the process
  • You must not disconnect the phone from the PC amid/during the flashing process

How to Unbrick Your Hardbricked LG G4

So far, we have deployed two (2) methods;

  1. The Loader.img Method
  2. The QFIL Method
Both of these methods successfully unbricked some LG G4 variants while some variants worked only with one method. The LG G4-H810 for example worked (100%) with only the Loader.img method.
And we have prepared all the unbrick files and tutorials needed to successfully unbrick your device using either or both of the methods.
Depending on your variant and the method you choose to go for, see the unbrick instructions below:

Possible Questions You May Have:

My LG G4 Is Not Listed, Can I Still Use this?

If your LG G4 variant is not listed, most likely, we do not currently have unbrick files for your device. You may let us know of this via the comment section or our twitter page.

I Have Similar Device Not G4. Can this Method Work for It?

If you have the appropriate unbrick files, you may give it a try but definitely not with the files meant for the LG G4.

Do You Provide Unbrick Files for other Devices?

Well, that depends on the number of requests we receive for the device and the support we are able to secure.
