Please help me, im not new to the phone and i think i read something about this somewhere on snowleopard jb, but i flashed the recently new one modeled after the ota without lgpst and i accidently ran my phone out of battery. Now i get to the splash screen see my desktop for litterly a second, and than i get a blue circle that rotates, than the phone shuts off and goes back to the battery charge screen (which stays bright black atm) I am able to get into dl mode, recovery, and bootloader, so i tried reflashing, no luck, i get to the optimizing software screen or whatever it is , than after it gets to 54 it shows the bootoff screen than the battery charge screen. so i tried flashing the early sl jb rom, mind you all have been clean wipes first. still no luck, same thing optimizing than boot off, tried nocturnal 2.0 same thing..... please help i cant figure out what to do, and im a locksmith and always on call!!! i know im an idiot for messing with the phone i need for work, but i had no problems before i accidently ran it dead on a call.
What version do we talk about?
Sent from LG E975 pwd by CM 10.1
same problem too
I got this problem too on rooted stock rom. Went to LG repair center and they said it would take 30 minutes to fix and implied the battery needed to be replaced. When i returned they said the phone is rooted therefore not covered under warranty. They wanted to charge me an exorbitant amount to replace the motherboard. im going to order a replacement battery from here http://www.etradesupply.com/oem-lg-optimus-g-e975-battery.html and follow the instructions on this video http://www.youtube.com/watch?v=qsEYh3z-NRU . Its worth a short as i very much doubt it is a motherboard issue
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. :/
Contact me over pm for details. I could manage that for you.

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:

I need help my galaxy nexus is not turning on. At first it would start charging when connected to a charger and i was able to turn on my phone(although it would not go past the google screen) but as soon as i disconnected my charger the phone would turn off(even though battery was nearly full).I performed all the wipes but it was of no help.My phone then stopped even charging.Now I cant even get it into recovery mode.
I would apreciate any and all help you can offer
Have you already tried swapping the battery ? Because I once was in a similar situation and changing the battery worked for me.

the battery is fine i have tried another battery but it didnt work
Not so long ago i tried to be the boss and took another guy's i9000 to install CM10 for him, i nailed it, it installed and it was working perfectly fine, then after several reboots the phone got stuck in a bootloop, then it got stuck in recovery, then it got stuck on the samsung logo, and then it just died.(stopped charging) like having literally a brick in your hand, no response.
If you've done alot of mods to the phone I'm guessing something inside died, get your phone to warranty and say you cant turn it on, they'll just change the motherboard and give you the phone back, if you had any custom roms they will never know.
my phone has no warranty that i could claim so my only option is to somehow fix my gnex

Well as i said, you have probably damaged physically some component on the motherboard, it needs to be changed so you can't fix it, find a Service that fixes android devices and tell em it doesn't boot nor makes a reaction at all, they'll prolly say they will change the motherboard if they have one and thats it.
*Edit*
I remember there was a thing called "jtag" that was able to debrick devices broken in such ways. But Rarely do services have them.
Try fastboot, download mode or omap

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.

Hello guys.I got a serious problem.My Nitro is dead.Thats it.err . . Well the phone was working perfectly fine.It was unbricked and rooted and custom rom flashed.I just about to sell it off to a buyer in front of me ,but then when the phone dead after i factory reset it.
Factory reset>rebooting>dead>scolded.
Now I cant even turn on the phone,even charging not working and when i connect it to my pc it it show QHSUSB_DLOAD.
I cant even get to recovery or download mod because my phone is dead.
Btw the rom that I flashed was cm10 by miroslav_mm.I dont blame the developer.
How to fix this(please dont say JTAG)?How much hope left for my phone?Should I just ditch this phone as Im getting headache everyday with it and it just become a dead load?
Please help me guys!
Sorry for my silly grammar and bad english :silly:
You could try removing the battery for a few hours, then put it back in, connect the charger, and try to boot the phone.
I ordered the phone on amazon (us) a few weeks ago, and got it sent to my country (Venezuela), and it's as you describe... I can't even charge it,I tired a battery from a working nitro HD, it didn't work either...
Is send it back but it'd be very extensive..

At last,fixed my nitro & i would like to share some solution,but not for DIY, but for getting a cheap price to unbrick from hard brick for your nitro , the repairer will usually charge you price for unbrick&flash stock but i found that they will charge more for flash to stock(gb 2.3.5) , so just ask them to just unbrick & tell them that you will do latter yourself , but make sure to ask if they will they half the price , in my country,malaysia i just need to pay them bout 24 dollar from the default price for about 54 dollar. I hope that this will help you all that hard bricked your nitro.
