unless somthing changed i didnt even know there was pinouts on the g4 like the g3 and 2
i may be wrong.
the g3s pinouts were under the metal shield
why do u need to force it to 9008 did u hard brick it or is it bootlooping on its own

no i tried to boot h811 marshmallow rom using emmc files from f500 and everything worked great till i saw the phone doesnt recognize the sd card so i tried to flash some of h811 emmc files and that was the dumbest move ive done in smart phone history
now the phone shows ? inside a battery symbol when the battery is taken off and no sign of life when battery is in it
certainly forcing the phone into 9008 mode and then flashing ls991 files which saved my phone for one time using qfil will save it for another time.
For now the right emmc files should be flashed in order to get out of this specific type of nonsense brick.
Im gonna try what is said here and see what it does but first im gonna check the voltage of these points with a multimeter

Buddy First Of All...
Remove the big metal plate...
Its easy it pops out.
Them on emmc right side there are 5 small golden points and on left side there is a ground point...
So on right side solder the 3 golden point and ground and connect usb cable to pc and dammmmmmmmm
Phone will be in QHSUSB_DLOAD 9008 MODE
Best of luck
Any help can whatsapp me

Tried it and it worked thanks:laugh:
Just managed to flash ls991 mbn files and then replaced them with f500l files(my phone is refurbished it says h811 but f500L is written on the main)
The phone boots up and every thing works great except one thing:
Phone cant read sd card But if i use only ls991 files i will get sd card working but no imei and baseband and camera
What the f is wrong with this damn phone guys????

Hmm So you got f500l
Well use the oldest firmware and flash it and see if it works
And if you get problem with imei I'll fix it

[HOWTO] Hard Bricking E975

Yesterday I manage to hard-brick my Optimus G (intl) E975. :crying:
The process was quite simple, root, unlock bootloader, flash CyanogenMod, flash custom kernel F93, install FauxClock (paid version on Google Play). In this app (FauxClock), in the screen gamma settings you have an option to download a kernel enhancer. I downloaded the kernel enhancer provided in the app and its name was something like "all_kernels_enhancements_mako.zip". After download, I booted in recovery and flashed that "all kernels enhancement" .... and hard bricked it was!
The phone now won't start and all it does is to blink an Red Led (of death). I can't go intro recovery with any button combination. Only the red led. I hopped that it lacks battery juice and I put it overnight for charging but no change.
It looks like the zip was meant for the Mako (Nexus 4) kernels, not for L975
I searched on the web how to re-write phone's boot images and I found that there is a JTAG method for that using a device called RIFF. It implies that you open your phone and connect some plugs and re-write the nand flash. I searched some more and I found a guy in my town that does this kind of things. I met that guy and, for now, it seems that the re-write process is available only for the e970, e971, e973 variants of the phone, but he will try it on e975 anyways.
Right now I'm waiting some news for this guy. Keep my fingers crossed.
Update 1:
That guy with the JTAG has a hard time making my phone to boot.
Meanwhile I contacted LG service and they told me that they can try to fix it but there is a chance that the mainboard has to be replaced(?) as the phone is not recognized by the computer. They also told me that hard-bricking can appear even when flashing official firmwares.
As I am in a big hurry with this repairing stuff I don't know what to do.
Update 2:
In the end, after 8 hours of hard working, that guy made the best finding the right file to flash with some international help, made the right JTAG shouldering and finally, IT'S ALIVE!
My dear phone is now up and running. I just rooted it, unlocked it and flashed CM 10.1 again with the F93 kernel. Fortunately I made a backup 5 days ago so I lost almost nothing.
It was a good lesson and a first in Romania

I don't have much experience but i have understood that JTAG is compatible with all the android smartphones, even there's a video in youtube explaining the process. I hope that works for you mate, I have my E977 hard bricked too but I'll take to SAT in a few hours. Good luck :highfive:

Thanks Unreal_Shogo,
I saw that movie yesterday and this is how I found out that there is a solution for my problem.
A few notes on hard bricked LG E975 in general:
- after a phone is bricked, don't try anymore to charge it, because it will only consume the rest of the battery. The phone after that many hours of charging it had only 3 volts instead of 3.7 minimum. Android phones control the charging process by software, not hardware. And if you push the power or you will connect the phone to the charger it will consume completely the battery and you can't stop it if you can't disassembly the phone and disconnect the battery
- this model, compared with e970, e971, e973, it is different and harder to solder the wires, because the JTAG connections are on the other said of the board, not like the one from the video.
- the boot it is not compatible with the other models and it is very hard to find the correct files. But with some stubbornness there is nothing you can't do
Not all the androids can be repaired with JTAG because the manufacturer sometimes disable it. So never be so confident, that you can repaire the phone with a few bucks and no need to replace the mainboard. For example Motorola had only 2 or 3 models witch can be repaired.
And finally I am glad that you already customized your phone like before you bricked the phone and you came to me.

Hello all,
I bicked my E975 using FreeGee app. I tried to unlock it and it gave me a error message. Than I tried to restore backup and I get error message, again. The next thing I did, reboot the phone. After reboot, phone did not power on.
I have all backup files (.img files includes m9kefs, aboot, boot, recovery, sbl... etc) and I need to find a way to restore it.
When I connect phone to PC, it detect it as QDLoader device.
When I plug-in USB, charging led powers up for 3 seconds and goes off. At the same time I can hear windows sound (plug-in and plug-out USB sound). I have downloaded KDZ image and KDZ updater but it did not detect my phone.
I gave phone to friend of mine, he have riff box. He tried to resurect it but riff did not detect (as he said) the phone. sound like a impossible. What do you think?
Can someone help me with this, please.
Sorry for my bad english :/
Zidan made it clear,not everybody knows how to fix it. yeah,your phone is hard bricked.
You have 2 choices : send it to zidanro or to warranty.but i'm sure the warranty is void.

Quoting my private message to marko_s for everyone's benefit:
Take it to a cell/mobile service shop and JTAG the phone. It means that your phone will be open, some wires soldered on the chipset and the propper files re-flashed on the phone using a special software.
JTAG soldering
Hello,
thank You for respond. I send it to ONE service guy, friend of mine, and he connected it to riff box. Riff did not detect the phone.
I'm only asking if there is another schematics/a tip to connect it to riff in proper way to get it work.
Also, what is possibility that there is something wrong with riff and or way that connects to phone and can not detect it?
I think can phone be bricked so hard that riff can not help in this situation. ?
It is not burned in fire. PC detect it. So I think that there is something wrong with procedure he used to connect it and "flash" NAND chip.
Let me know if you have any suggestions. Phone is out of warranty, it's opened and soldered.
Thank you guys!
Hi, youre a lucky boy
Haha, you can install a mako rom, without brick, it will boot!
belive me!
(issues are no radio (2g, 3g etc..) , invent volume button, camera (not testet
i think combination e975 kernel and mako patch was bad idea
Nice joke
Hehehe, nice joke.
I must fix it or throw it in the trash. I do not have to buy Monalisa, I can hang it on the wall instead.
Can you tell me where JTAG pins are located? Under the board or on the top? I'm not asking for schematic.
I removed the cover and battery connector. I can not see any soldering pins and solder traces. I did not remove the board.
Help is really needed and appreciated
Thanks!
Wow.so you really wanna make a decorative object).look on youtube,there is a guy jtaging an e970. As zidan said,on e975 the jtag pins are located on the oposite side.

I sent my to one service technician and he repaired my phone using RIFF. He had to remove JTAG connector. It is well done. I can not notice that it was there at all . I pay 25 EU for repair. It's not big money for that kind of repair.
What I will do, when I find a time to do so,. I will backup my phone using QPST and post files here on forum.
I have to put my phone in some kind of recovery mode and so on. I have no time for that, at the moment. I think it should work/help to repair your device(s).
Regards!
u sayed battery is dead?! try to open the phone and disconnect the battery (2 screws) and connect agayn and try.... for me it worked after my phone got very hot.. (nothing helped...)

Today i also managed to hard brick my phone. There was not a single notification that my phone is alive. I too found that QHSUSB at device manager.
But try one thing - 1) Plug it to wall charger for near about 15 mins. 2) Then Press Both vol buttons And then the power button too
( I tried Vol+ then Vol- and lastly power button ) Hold them all.
3) and when it shows charging screen keep pressing vol up button 1 time / sec.
You may not get succed for the very first time.
Try at least 4-5 Times.
Hit thanks If it Works :laugh: :good:

If it's appear like that in the pc, looks like your internal memory has been wiped (or partitioned), happened to me before, i sent it to lg customer care and they had to replace the hole motherboard... sorry to hear...
When u use the swapper, choose mdblock1 instead of mdblock0, cuz. it is the internal memory and 1 is the external one!
Or use another swap app that have a advanced settings!
The problem is LG G Pad is not available for my country (Indonesia). I bought it from Hongkong. When I contact Indonesia's LG service center they seems cannot service my tablet. So shame.

Not sure, but if u have qualcomm hs-usb qdloader 9008 (COM3), then, it is a motherboard fail, means that not hole motherboard is effected (MAYBE if the hole motherboard effected, u will not get any sign, even in pc), but it maybe the internal memory fail, but otherwise u cant replace only the Internal Memory alone, u have to get the hole motherboard, so u can bring it back to life...
Thanks for your answer.
Now, just waiting a month for the motherboard to arrive. So expensive [emoji31]

I feel for the OP, as I too, have hard bricked my tablet when I tried creating a swap partition via swapper. In my case, all black screen, no response when I try to power on the device, no nothing....
The only sign of life, is that when I connect the tablet to the computer via USB,i hear 2 faint beeps but then nothing....
Does anyone have any recommendations, apart from replacing the motherboard? I find it a bit too expensive, as its almost 2/3rds the price of a brand new tablet.
Does anyone know if JTAG will work on the LG G Pad 8.3? Also if anyone can recommend someone who can fix it, for a fee ofcourse , please feel free to PM me. Thanks

Nope. I mean jtag, a device that is soldered onto the chip and hardcode data directly into it. You can use it to restore a hard brick. i think i saw from somewhere that the jig wont work. But i think Jtag will stand a chance.

After I change the logicboard, everything works fine again to stock 4.4.2. The only downside is now my G Pad screen doesn't stick with the back part of the G Pad because of the teardown.

You can however reach the ports? headphone and USB?
headphone and usb are fine. It's just the bottom corners of the screen now slightly lifted up because cannot stick with the back.

[Q] how the hell did the local shop is repairing my LG OG(hard bricked) without JTAG?

By mistake i flashed nexus 4 kernel to my og and hard bricked my phone. I went to local shop repairer and they opened the back of the phone and connect many wires to the board and connect it to pc.They did something in their pc(something in cmd, don't know exactly) and they said that software installation process went till 71% and the phone switched off because of low battery.Is this really possible without JTAG? or they telling lies?
That is in fact JTAG Riff. They open the phone and connect some wires to the back of the phone and transfer the needed files to bring back the phone to life.

Help a Hardbricked LG G5

Okay!
So I bought an already used LG G5 Sprint LS990 and it was locked.
I took it to a store to unlock via a software and it worked after putting my sim.
Then, the phone became very hot and went off. It refused coming on. It was more like a hardbrick. It doesn't come on. No recovery or download mode. No display on the screen when I plug in the charger (the phone just feels warm after a while). Also, when I plug it to the computer, there is no connection sound and I checked device manager, it doesn't show anything. No Qualcomm HS-USB QDLoader 9008 or BULK whatever...
I got tired of trying. So I abandoned the phone for about a month.
Last week, I plugged it in again and omg! It showed the battery icon and it was at 0%.
I left it to charge to 100% and I put it on. It got stuck on the Sprint Splash screen and went into a bootloop.
I removed the battery and reinserted it. Now it won't come on again. It's back to being hardbricked.
I even bought a new battery just incase but it didn't work.
It still doesn't connect to the PC.
I don't know what to do.
Can anyone please help?

Hey.
I got it fixed, using the weirdest method ever:
By cleaning the panel with petrol and heating it with soldering iron.

I waited until the petrol had completely dried off before using the soldering iron.

I've tried the steps and my sim didn't work. I was thinking it was because I was on nougat.

Didn't you say ZVC upwards cannot downgrade?
Isn't ZVA lower than ZVC?

I cant remember exactly but yes in gen you cannot go back to MM though which is like zv6 or 5
You would have to look in the do not downgrade thread

Use a pin to open the tray, it comes all of the way out.
