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...)

Technician is from Bosnia And Herzegovina, city Zenica. He is precise in his work, as I saw.
I'm electronic engineer, but he is more than that . Last option would be to send your phone to him to repair it. :/

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:

Hi Everyone !
I have a Desire HD and it bricked last sunday evening. It's only half year old, so I took it back to T-Mobile (I bought it from them). But it's rooted and Radio S-OFF-ed when died. Can the service establish that I rooted and S-OFF-ed my phone, or no ?
Thanks in advance !
If it's totally dead (no bootloader access or charge light) then they won't be able to tell. They'll fix it without any knowledge of software changes.

Yep if its completely dead they wont bother repairing it, they'll just replace the motherboard. That way they have no knowledge of what you did to it.
Thanks for the answers,I'm happy right now,because you have the point:absolutely no sign of life. No charging light,no bootloader and no any happening when I press the power button (same with another battery too).
how did you manage to do that? It will be good for others to know so that they dont make such a mistake .

I don't know. Here's what happened:
1.: I use Opera Mobile for web browsing and the past few days it's become very slow. Sometimes the only way to close it is press the Home button and close it in task manager. I thought it's a software problem, so I made a hard reset, but it's not resolved my problem. Mean while I saw the news that HTC will not refresh the Desire HD to ICS in the first line, so I downgraded it and flash the latest NDT MIUI ROM.
2.: Next day I connected my phone to my PC and realised there is no communication between, only charging. I tried it in other computers and other USB cables, same result, so I wanted to back to stock. My only problem was the Radio system. I was still S-OFF-ed. I searched so many forums and I tried to get back Radio S-ON in Terminal Emulator, but it didn't work.
3.: Tried some instructions without any result and finally after a reboot procedure the phone didn't wake up anymore. No reaction for the charger, no reaction for any button pushed. Nothing. Took it back to T-Mobile and they check the battery because they thought maybe that caused this and they said it discharged over.
And now I'm waiting for an SMS or call how is my phone now
goodluck with that
Got it back from repair service. They changed its motherboard,so almost I have a brand new phone now I'm so lucky I guess ... huhh ... sweating a lot,but now I'm happy

If you plug it into your computer in that state, does it ask for qload usb drivers? if so, Its a true brick, and there's no way they'll know what you had going on. I had mine replaced in June this year after mine was bricked.
So I was turning my optimus G back to stock rom. I was installing kdz and it worked, but it turns out that it wasn't for the optimus G. Now when I try to turn my phone on, the led flashes red and turns back off. When I connect it to the computer, QHSUSB_DLOAD comes up. Please help me!!
nobody here can help you. you can send the phone to warranty. tell them it just died. there is no trace.
when you hold vo.l up and vol. down together... appears the download mode?
first try to go to download mode or reset your phone to factory setting. Can it work?
It won't matter what button he's pressing. Qhsusb_dload means it's hardbricked. The easiest way is to send it to warranty. There,they will try 2 solutions: if the mainboard is healthy,it will be jtaged. If the jtag won't work,they will replace the mainboard. Both solutions will not reveal the fact you broke it. Oh,forgot,they could give you a brand new phone too,if the repair is too expensive.
Sent from stock LG E975/smart phones,dumb people.
well, i tried to enter download mode and sadly it doesn't work
i went to warranty and they said it will cost me $290!!!
wow. what did you told them?i hope you didn't tell them you tried to use kdz updater . You should've told them the phone just died . You were away for some time, the battery was empty, you plugged it to charge,but it wouldn't start up.I did this with a galaxy s 2.
Now,you could go to a gsm service for JTAG. it will cost you some money,the average is 30-50$,depending the country. Of course,if the mainboard is still healthy. if not,well....basically the mainboard means the whole phone. there are few things that can be detached from it(antenna with buzzer, the camera, the volume flex,the charging port,the 3.5mm jack port).
Not to mention the eventual replace can only be done in an official LG service, because the imei must be rewritten(it can be done in a gsm service,with the jtag too).
My advice is to look for an optimus G with broken display,to take the mainboard from it.

Hi there, I hard bricked my Tab S 8.4. No reaction to anything I did (key combinations, let it charge for hours, stuff like that). Don't know how it happened but it just crashed to death shortly after installing an inofficial Lolloipop build from here. I don't think a ROM can make a device not turn on at all. My money is on hardware failure.
Anyway, brought it in for repairs (willing to pay since I knowingly voided the warranty). Got the call yesterday. They said the software had been tampered with and they can't repair it. I objected that the software won't break the hardware but no dice. They won't even do it for cold hard cash.
BUT: To see the 'illegal' software they HAD to get the thing to turn on . And if they got it to turn on somehow, so can I. Or... am I completely wrong there and they have some magic fairy dust?
Any ideas on how I could accomplish what the repair guys could obviously do? There is no important data or anything on it so I'd be happy with Odin mode, CWM or whatever.

I kindof had the same problem, but got mine repaired.
May I ask where you send it to for repairs? Was it Samsung or a local repair shop that told you they could not fix it?
And did they send it back to you? Kindof weird they won't fix your device after you say you are willing to pay for it.
Depending on where you live, Samsung covers a lot of 'problems' in the first year of the standaard warranty.
As for turning on the device..
What options have you tried yet?
If you connect the tablet with usb to your pc and turn it on, does it get recognized?
And if so, as what?
But if your screen doesn't turn on, you're probably going to need repairs anyway.

Over here you bring it back to the shop where you bought it. They will try the simplest solutions in house but usually send it back to the manufacturer. I think the information came from Samsung directly. Another theory I have is a simple lie. They tried it in house, nothing came up, some clever guy screamed 'CYANOGEN!' and they all high fived (I have a vivid imagination )
As for turning it on: tried everything. It's not only the screen, it did nothing at all. No signs of life whatsoever. Of course the PC wouldn't recognize it since it was turned off.
I'll pick it up tonight. Maybe whatever they did to see the software tampering stuck and it will at least go into Odin mode. I can work from there.

It simply reset itself after the battery completely died. Black screen and no response doesn't mean the device is off.
As soon as they switched it on they would have seen knox had been tripped.
Sort of did you a favour by telling you it wasn't bricked.

Comforts me while ROM developing that the only reported case of a hardbrick was here - and the battery just died.
Hi all, ok tonight/this morning at work while on my break i went to do my usual thing of having food and watching a tv show via cartoon hd about 2mins in and my phone switched off.....now i thought it was dead so plugged in the charger but no led light, or screen on to say its charging.....i did a bit of googling and find out about the bootloop thingy buuuuut mines not looping, its swtiching on to the LG logo [i did the bootloader unlocker thingy etc so it says tha in the top corner] then it goes off.......i also get pulsing blue led lights too.....if i press, hold the power button after i get nothing, i have to take the battery out and then its rinse and repeat
Hi,
Same thing happened to me today. I was taking a shot and it switched off and same scenario.It seems that we had encountered an bootloader brick in which our device enters in some special bootloader mode in which when you connect it to the computer in the device manager it shows up as Qhsusb_bulk. I read the whole internet and there is a similar brick with G3 the guys were able to fix it. Even there is a tutorial on how to do this which I think is applicable to our device. I was able to install the required drivers and etc. but there is one big problem - I followed the guide and came into one serious problem - we need a special mbn file so we can recover our device and the sad thing is nobody on the internet doesn't have it still. There are many people like us who got selfbricked G4 and cannot fix it without this file. Please if somebody can help us please share the file so we can fix our devices. THANK YOU !

on G2 you get security boot error phone is detected as QHUSb_BULK. on G2 the fix was to enter download mode. in G2 vol up then plug usb.
using TOT method and flash tools . flash stock firmware fixed my soft brick.
not sure about the file you mention, maybe you do need it..

I have the issue. I don't do anything special but my phone reboot and stuck on lg logo. But now my phone doesn't want to boot. Sometimes he detect when I'm trying to charge it but often not. Yesterday I boot on download mode and recovery but today it's impossible... I think I have some hardware issue ? Or software with the bootloader...
I don't know how to fix that without access to download/recovery mode :crying:
Same here. Sometimes it boots into recovery/download but most of the times it doesn't. It's a hardware problem I think as LG officially confirmed that there were problems during the building proccess of the first G4 series. I don't want to sound bad but soon or later all phones built before october last year will get into bootloop. I was hoping it won't happen to me - I'm very light user with only light standart apps with no games and other heavy stuff, so the problem wasn't caused by overheating by heavy multitasking. Anyway it happened and I'm pretty sure it's harware related but if somebody can provide the tot and mbn files I will be more than happy to try the g2/g3 unbrick method. The main problem is that these files are not available for h815. I found on other forum tot files for other variants than h815 So if somebody have the tot filesfor h815 please share so we can try to unbrick our G4. Thanks!
same thing heppened to my g4 this week. i called lg last night and they agreed to repair it. i'd just gave them a call.
I sent mine for repair today. I hope they will agree to repare it even that it's with unlocked bootloader and with rooted custom rom !!! What you think ? Will I have problems with them because of that ?
Happened with my phone as well. It was rooted so i was hella scared if they didn't accept my phone. But soon they told me phone's motherboard has gone bad and will be replaced. Got my phone with a brand new motherboard after a couple of hours.
P.s. all your data will be gone

So the same problem just happened to my lg H815 with unlocked bootloader, am really f***ed without my phone, gonna call LG UK tomorrow, anything in particular I should say? also looking for solutions I saw many people are starting to have this issue now too - any official comments from LG?
P.S. if you have an LG G4 you should start backing up all your data now
This literally just happened in the last 15 minutes to me as well. Random reboot right after I woke up the phone and now stuck on the LG splash screen. Light user here, never did anything with the phone that would have heavily stressed it physically or computing-wise, so I also concur it's an inevitability for earlier runs of G4 phones.
Luckily, I backed up everything through TWRP last Thursday by chance because I was updating Xposed to the latest version and swapping to a faster 128GB microSDXC. At worst, I might have lost a handful of unimportant text messages.
Not worth the time to try to figure out any cheap fixes myself, I just got done submitting a repair request to LG.
I ordered LG G4 H815 and I hope to not see any kind of these issues

Hi guys, I would like to share my experience with a bricked OP3, I own my OP3 about 3 months ago, currently I'm running 3.5.3 CB, and zero problems with the device until now.
My younger brother has his OP3 about two months ago, and I don't know what's he thinking but he flashed a CM12 on his OP 3. Really I don't understand why a person could do that, however he really screw the phone. Never return from death.
I've tried all guides and possible solutions for the brick, there is no bootloader, no recovery, no vibration, no anything. The phone is really dead.
The device it's recognized by the pc after installing qualcomm drivers and after pressing power +volume up buttons, like qualcomm 9008, and it gets recognized by the unbrick took (msm download tool v3.0).
And when I start the tool it start to flash anything goes apparently well, green successful message. But phones continue as a expensive brick.
When I plugged the phone like it should be, pressing only volume up and connecting cable it gets correctly recognized like qualcomm 9008, and by the tool, but when I hit start, it give me that saharra communication failed message.
But when I unplugged and connect again and hit power + volume up, gets recognized again but I doesn't have that Sahara error and even its flashed with the tool, but phone continue to be dead.
I've disassembled the phone to see if I can see some simple trouble in the hardware maybe, I tested changing parts with my phone to see if the trouble is in some charging or display or anything like that, but all parts are working well.
Even I've put my motherboard on the dead phone and it works perfectly.
I can give up to leave this phone dead like that but I've tried anything possible so I'm planning selling spare parts.
In my country I don't have any SAT or any place like that to repair the phone.

Damn that sucks. He probably flashed the wrong rom or something else. You should contact oneplus and see if they can do something about it cuz i reckon your brother's phone still has warranty.

Really sorry To hear it?? BUT CM12 rom??? ? where he find it....?? if you hard bricked phone.. go to a expart devs shop.. he may be solved your problem
If your phone will not power on oneplus service center person are also not able to check how your phone will dead i think so you can claim the warranty.
CM 12 roms developed for One Plus 2,I don't really now why in the hell he do that, but he did it: https://forums.oneplus.net/threads/cyanogenmod-os-12-1-yog4pas1n0-update-25-08-15.349531/
What do you mean with expert dev shop?
Anyway I didn't think I will find some like that shop, I'm in Buenos Aires, Argentina, and maybe 99% of the cellphones technician didn't know anything about Oneplus 3,that's the reason why I've disassembled by miself.

No wonder why it got bricked xD. You should see if you still have the warranty for your brothers phone. Contact oneplus and see if they can replace the phone.
I contact oneplus and they say me I wanna contact my seller to review warranty, but I bought on "Mercado libre" some trading online place like ebay.
So we are in a really bad situation.

Well ****. Can't you contact the seller that you bought it from? Also your brother should be careful next time he flashes a rom. We all make mistakes, sometimes ppl have to learn it the hard way.
Yes this will be the first phone since 2005 year when I started to flash custom roms on samsung omnia i900, thats really dead, I bring from the death a lot of bricked phones. But this phone is really dead so I think I will start sparing parts, maybe we can recover some of the money invested on the device.
