I bought LG Optimus L5 E610 few months but i rooted it just few days ago. After i rooted it i installed ROM Manager and installed CWM but my device was not in the lost so i selected LGE Optimus M+ (idk why). Then a friend of mine told me about the "cool app" Beats Audio Installer and i installed it. After i rebooted the phone the speaker started making crazy sounds. I read in the app's site that i have to install a ROM to restore the original sound driver. I decided to install the stock ROM from here http://forum.xda-developers.com/showthread.php?t=1790342 but when i tried to install it it asked me to boot in recovery mode and i accepted. After it restarted it showed this " Secure booting error! cause: boot certification verify. Now I want to restore it to its original state but i don't know how so please help me fast.
Read this, to install the correct CWM for your phone (you'll have to download the .img yourself):
http://forum.xda-developers.com/showthread.php?t=1827723
Then, boot to recovery & flash your fixes from there.
Alternatively, you can use the KDZ flasher to restore to pure stock.

Try connecting your phone to your computer and using ADB to flash a new recovery to your phone.

Use this to download your original firmware.
Use this guide to flash it with the KDZ updater.
When it's done, you'll be back to stock ROM, and all your data will be gone. Don't play with your computer or have anything else running, because if your computer freezes during the flash (or you remove your phone's battery) your phone will be hard-bricked.
If you would rather save your data & only flash CWM onto the recovery partition, you need to find & download the .img or .zip file of CWM which was made for your phone, then flash it using Android Flash Recovery.

Build a brick wall with it. It's a brick.
Soft brick means it's recoverable. Hard brick can be sold for parts.

Yes the tool should work even if you can't boot your phone. If you hard bricked your phone you will need to use jtag to unbrick it.

If your phone is only soft bricked LG will easily be able to tell you rooted it and "installed unauthorized software" on your phone and they very likely won't honor your warranty or offer to fix it. JTAG essentially allows you to restore your phone to its original condition if you have a brick or some soft bricks. What they do is they take apart the back of the phone so they can access the JTAG pads, they then solder wires to the JTAG pads. Next when a connection had been established they hook up the wires to a riff box using a ribbon cable, they then attach a cable from the riff box to the computer. From here they use a special program called Riff Box JTAG manager, to resurrect your device (Restore bootloader, etc.). After that they flash the original firmware that came with your device and your phone should work again.
For more information on JTAG check out these links and video.

Word of warning: Technically deliberating bricking your phone and getting an insurance replacement is fraud and is a federal offense. The right thing to do would be to bring it and attempt to explain your situation (Or you could play dumb, and maybe they'll help you again they won't be happy and you could be in trouble if they figure out your lying) there is a possibility they will fix it for a reasonable price. In the end you unfortunately might have to buy a new phone,

Unless you know what your doing you could destroy your phone to the point of it being beyond unbrickable, if LG says they won't repair it for you look online for a local shop in your area that's reputable and knows how to JTAG phones back to life.

Hello Guys!
My friend bought a SGS2 and he whanted to root it and to put MiUi on it. Now he unpluged it while it was in the Odin doing something with PIT...
It stopped and now he can't go anymore in the download mode and the phone remains black...
is that a full brick? is there any chance to run it again?
do you need more informations?
I looked throuth the threds but i couldnt find something like that...
i hope anyone can help
Will Samsung repair that with Warranty?
Can i know why he disconnected his phone during using something with Odin?!
He made a Solid Brick he cant do anything else than Warranty or JTAG..

It's not the most correct thing to do (actually, not at all, it was your friend's fault entirely, also voiding the warranty), but your friend can tell them that the device began to heat while charging, he unpluged it and it died, sometimes it happens...
As for the JTAG you asked on the other post, it's a physical connector inside the cellphone used to write the flash memory, it involves opening the device, pinning some terminals and programming via PC, it's pretty common on embedded devices to load the program for the first time.
There is still a chance to get the phone back to its senses!
you will need 2 people to do this
read all 5 steps then only proceed!
1. Remove the battery.
2.Start odin in your pc.
3.connect the mobile to the pc using cable.
4.keep pressing the keys required to get in download mode. i.e. power+home+volume down key.
5.ask someone else to put the battery in your phone keeping the keys pressed!.
if every thing goes right Odin will detect the phone Flash it with a good rom you know which works! and never take out the cell from odin when its being flashed until odin says Success!

Afaik u never supposed 2 use pit options in odin for gs2 otherwise u end up with a brick anyway regardless if u remove the cable or not. perhaps read more and be more careful if u ever decide 2 flash again. i would not be happy with that friend lol.

Hey guys. So, I bricked my phone. I installed RomManager, then ClockworkMode through it, thus I knew that this phone is not supported. It wasn't there in that list, so I chose Commtiva z71 or something like that. My phone doesn't get in download mode anymore. Could this be fixed at home? I really don't want to take it to a service centre.
Please help me. Thanks!

no need to pull battery out and insert it back just insert the battery ,hold down the option key & insert usb cable thats it....but none of these gonna work you will need JTag to flash
You can even try JIG. Because, you've messed with recovery and boot partition but not the arm11boot (bml8). So, JIG (search Google, it is as cheap as $2 and you can even make one at home) can help you.
If it didn't, just search for JTAG services nearby your area. They'll charge you $20-$40 and your g5'll be alive.

That's not true, sadly. ROM Manager embeds a version of flash_image that will try to flash a boot image to bml8 if the device is not properly recognised. That's what happened for the OP, so a JIG will not resurrect the phone.
Oh...Sorry, I didn't knew that! So, final option left for OP is a JTAG flash.

Hello,
My Samsung Galaxy S2 is bricked. No way to enter download or recovery mode. Black screen... nothing to do to fire it.
Probably the bootloader is corrupted.
Does exist a tool for Exynos 4210 / S5PC210 like the one from Adam Outler "Unbrickable" for Exynos 3110 / S5PC110 ?
Thank you,
Guillaume
Ps. no need to answer about JIG, it doesn't work in this case of figure. JTAG tools exist... Yes I know! thank you BUT needs to solder a tiny tiny JTAG connector... and I don't own a RIFF JTAG Box nether a schematic of JTAG pinpoints on Galaxy S2 mother board...
No way you can fix it. Take it someone who does JTAG repairs or get the MB replaced.

May I ask, what are you exactly trying to point out? If you have a blacked out screen, with no power, recovery or download mode then I suggest you take it to samsung service centre. JTAG does fix dead bootloaders but you will need some experience of soldiering and wiring.

I said if odin can detect it on a black screen. It can be fully repaired with JTAGging! If you go to samsung service centre they will say the board needs to be replaced and charge will be high if you are out of warranty. And yes you need to know some soldiering if you have the jtag box. Or else ask someone who can give this service.

I see.. Before you do JTAG, do you have "some" knowledge of the JTAG Riff box? Yes the Samsung service center do rip people off .. However the JTAG box is not cheap whatsoever.
I'm just wondering if you can completely Hard Brick a LG G2 to a point, where there is no revive possible.
I can purchase a cheap LG G2 international version, but the seller says that he broke it during flashing a Kernel.
Can you for example revive a phone,that had a Kernel from completely different phone flashed?
Any insight would be greatly appreciated.
Sent from my C6503 using Tapatalk 2
If it's true he only flashed a new kernel then u can restore it. If he messed with the partitions then.... No. If he used a broken usb cable and fried it....
Well ask to try the phone before u by it. Also check if it's stolen
Alright, I gathered some more information from the seller.
He tried updating TWRP, but he followed wrong instructions from some website.
He can´t enter Recovery or Download Mode on the Phone.
The Display is active, but only Backlight.
When he connects the Phone to his Computer, it shows multiple Mass Storages, but the LG Software doesn´t recognize it.
Is this a common problem, that is easy to fix, or should I rather wait for another Deal to come up.
p.s. I asked him for a receipt, and he says that he has one.

If the guy was updating through TWRP, he probably have some knowledge on the matter, and the chances that he bricked it for good is high.
When I messed up my G2 a few times, being able to enter in download mode was the hint that the phone was revivable, if him really can't enter the download mode, then it is probably a bigger problem.
But the question is, by buying this possible lemon, how much will you be saving compared to buying a brand new?
If it's showing up like that, if you have a Linux machine you may be able to use dd to flash factory images to the partitions. There is a guide to it somewhere on here. But even if you were successful in flashing those, it really depends on how badly he screwed it up. In particular I really hope he didn't damage or wipe his efs. Or at least has it backed up.
Honestly, I'd point him to the right guides and have him fix it. If he screwed up his efs, or messed the partitions up, or fried something, it's dead and not coming back. If all he did was flash a kernel in twrp and it was actually from this phone and it was just a bad download or flash or something, then you'd probably be okay, but if that were the case you'd get a secure boot error and still be able to enter download mode. Personally, I would not buy a phone that won't boot, especially if the seller isn't even sure what's wrong with it.

sounds recoverable, if there is a backlight and mass storage comes up that's good, you can dd partitions with linux
no backlight + no recognizable usb device at all = bricked
still, buy at your own risk
It is.. i just did by flashing a broken rom.. sent it to the repair center and they replaced the motherboard
Right, I asked him if the Device shows as qhsusb_bulk in device Manager, and it does.
The only thing that worries me, is that there is no Boot Logo, most of the people in the Linux Fix Thread atleast get a LG Logo and not just Backlight.
I´m really unsure what to do, I can save like 150€ by buying the broken G2, but well . . . I dont know if I can fix it.
Another problem is, that I have not a single clue on how to operate Linux/Ubuntu, and the only real fix requires either of those

Just look up a guide on how to install an Ubuntu virtual machine. You should be able to connect your G2 to that virtual if you let it capture the USB port. If you can get it cheap, buy it and try to negotiate so you might have a chance on selling it for higher later on if you can't fix it. To me though, it sounds quite fixable, I would go for it.

this doesn't really matter, when I was trying to mess with the bootloader and corrupted it a few times I've never had the LG logo, as long as it comes up as storage you can DD it - the only time its a true brick is with no backlight and no usb device
if theres no boot logo you probably need to DD the aboot in

That's actually just killing a fly with a sledgehammer. 99.9999% sure you got a softbrick.

- Factory reset? Freeze
- Normal boot? Stuck at bootlogo
- Download mode? Stucking at the loading screen

Alright, I gathered some more information from the seller.
He tried updating TWRP, but he followed wrong instructions from some website.
He can´t enter Recovery or Download Mode on the Phone.
The Display is active, but only Backlight.

I had that problem when updating TWRP too. You have to be careful because these recoveries are only made for specific firmware versions. I cant remember how I fixed the issue after only being able to get a backlight on and no image, but I did fix it and my phone works fine. I do think you will need the TWRP files already on the phone to fix though, so you can somehow manage to flash back. They will need to be on the phone since you can push anything via ADB

i've been in this bricked situation when i was trying the 4.4.2 update manually...completely bricked, could not get into download mode too...so gave it to the service centre which at first said the main board will have to be changed when recovering through software upgrade failed...next day i got the phone back as they managed to flash the software back on it...
does not end here...i tried to flash optimus g pro 2 rom through twrp and same thing happened again...but was lucky this time as i could enter download mode and flashed kdz to recover...

I'm just wondering if you can completely Hard Brick a LG G2 to a point, where there is no revive possible.
I can purchase a cheap LG G2 international version, but the seller says that he broke it during flashing a Kernel.
Can you for example revive a phone,that had a Kernel from completely different phone flashed?
Any insight would be greatly appreciated.

And yes i truly believe that our device can be hard bricked like i did mine today.
I tried to compile a custom bootloader for G2 using Qualcom's sources and fraction of LK. But in doing so i left my phone in a quasi-state where it will not connect as a usb device coz it does not pass the bootloader (Although bootloader is working as it should). .
So the only two option remain here for me is
1. To send phone back to LG service center where they'll do idk what.
2. To use JTAG or short the ic (Wonder if it could be done ) i.e manually open the phone and boot into the primary bootloader(Qcom legacy BL).
See that's how you can hard brick ur phone the right way

Your LK build wouldn't have matched the sbl1, anything other than LG's signed aboot wouldn't work.. /:

But it did work coz our bootloader enfoces the signature check not in the sbl.(Our Primary boot loader)
i'm sure of it because it tries to go to download option but freezes at initial stage.
had it been the case my device would've been detected as qucom_bulk device or so..

You my dear friend are a victim of a curroupt bootloader seqence(NOT THE CoRRUPT BOOTLOADER) i.e
Your phone would start something like
1- EFI initialization ok
2-Primary Boot Load -ok
3-Vendor Boot Load -ok
4- Error unable to find proper boot sequence- system halted
So ur best options are the one that i've stated just above this thread.
My case. I root and flash custom recovery then apply OTA = medium brick. Download mode was not functioning, only recovery. To make matter worse, I flashed KK stock rom through ADB in recovery = super brick. Then I went to LG service center with poker face asked for reparation. They asked (confirm) whether your phone is rooted or not (they had already know though) and I just said like It is my sister's phone. Then they they open the phone and maybe directly format the sd card with some stuff. My phone is restored again afterward. In my opinion, software modification can always be repaired unless you fry your phone through overclock or overvolt.
