Super hardbricked lg g4 please help - Android Q&A, Help & Troubleshooting

hello i flash a wrong firmware on my lg g4 h818p
now the phone is totally dead:crying:
how can hi unbrick it with usb cable

Sounds like you're in trouble... I haven't seen any guides for the G4. I have successfully revived a G3 in this state with this guide: http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359 . The tool supports many models, but not the chipset in the G4. Here's a more generic guide : http://www.droidsavvy.com/unbrick-qualcomm-mobiles, but others there mentioned it didn't work for the G4 either. You might have to look into taking it to a professional that has a tool like an Octopus box or something of the sort. https://www.youtube.com/watch?v=bJtWmAjL8tk

ok thanks y pro i will try this guide

READ BEFORE POSTING: How to tell if you have a G4 or G3 device & how to CID-unlock it

READ BEFORE POSTING: How to tell if you have a G4 or G3 device & how to CID-unlock it
The only visible difference between a G3 and a G4 device is when you soft reset your device and looking at the IPL and SPL version numbers that occur during startup.
G3 DEVICE: IPL/SPL: 1.XX or 2.XX or 2.XX.00X (only two zeros)
G4 DEVICE: IPL/SPL: 2.XX.000X(three zeros)
Note, X is representing a number.
So, how do you go about to CID-unlock your device? First, do you really have to? Well, in one word YES!, in order to install most of the custom-made ROMs from this site you have to have a device that is CID-unlocked...
If you have a G3 device the solution is pretty straightforward. just look here...
If you have a G4 device you have to go to imei-check.co.uk and pay £20 in order to get it unlocked. But you can help develop a solution that doen't require you to pay for it. Have a look at this thread.
NOTE: There are several posts that mention this subject, some claim that using the imei-check.co.uk method will not CID-unlock your device but only unlock the SIM. THIS IS NOT CORRECT! Your G4 device will be unlocked after this procedure.
Finally, never, ever, flash your G4 device with a ROM that is intended for a G3 device, make sure that is either made for G4 or doesn't contain a bootloader. If you for some reason you do, you'll have damaged (bricked) your Wizard permanently...

As far as I know the brand of the chipset is the only thing that's different. It's also been speculated in that due to the newer bootloader present in the G4's they have updated security measures when upgrading...
Hello,
You know if this unlock work for French FAI, specialy "Ten Téléphonie".
Many thanks, soon...
G4 or G3
ipl 2.18.0001
spl 2.18.0001
G3 or G4
Are you kidding me?!! I clearly states in my first post that if your ipl/spl is 2.XX.0001 it's a G4!!!
Yes but it is also possible to have a g3 with 2.xx.001.
So it's a bit confusing.
Anyway how do i determin wich update utility to use?
look at the number of 0
Ok ok... updated my first post to make it clearer
alright checked!
Thank you

good answer!!!!! really!!!!!
how to see videos on youtube?....... what program/drivers do i have to instal? this is the question!
Mine even has 4 zeros (2.06.0000)... i think it is a G4 also -.-
Ok, sue me if this has been asked before....I could not find it anywhere. On my Wizard the RED Vodafone splash screen covers the IPL/SPL versions on start-up. Anyway to find out in some other way whether it's a G3 or G4?
Finally, never, ever, flash your G4 device with a ROM that is intended for a G3 device, make sure that is either made for G4 or doesn't contain a bootloader. If you for some reason you do, you'll have damaged (bricked) your Wizard permanently...[/QUOTE]
How to know which ROM is intended for G3 or G4 device ?
HELP !
I tried to flash my Cingular 8125 with the latest ROM not realizing that I had a G4 device. Now all I see is the RBG screen and I don't know a way out.
I will appreciate any help to bring my 8125 back to normal.
Thx
Finally found the rom which can work with the G4 device. I think my phone is CID locked but still it worked. The ROM was 'Wizard love '.
It good to have my phone working now !
Thank you guys!

You will be in the same situation as me. KingRoot right?
I have the same problem with my LG Pheonix 2 (LG-K371 from AT&T) and cannot find the firmware anywhere ...
And you're not going to find it. Its AT&T, they won't let LG give the firmware out, thats why there's no kdz, no switch or bridge. You have no choice but send it in under warranty and hopefully they won't deny coverage. The LG service center in TX is notorious for denying repairs under warranty!!!

LG G2 D618 mainboard works on D620k version?

I briked my phone when I tried to update via LG flash tool 2014,
My lg model is D620k
My question is: Can I use mainboard of D618 version on my D620k?
I want to replace it but I do not know
It should work, but since I haven't tried it, nor anyone else, I don't know.
Remember, whatever you do, you are responsible.

Thanks you for your reply.
I research, D620k and D618 touch screen and LCD is the same, so I can replace the mainboard it should to work.

I need a firehose programer for lg g5 phone. Plz, help me.

I have tried cross flashing my lg g5 Verizon brand with sprint one and now it is hardbricked.
I hope if anyone has a firehose programer that works on bootloader's with antiroll back v1 and above.
There's one programer that is used FOR lg v20 and g6, but it only works for G5 devices with ARB 0.
