[How TO] Unbrick, hard bricked LG Optimus One (P500)

I was using
Device: LG Optimus One P500
Recovery: ClockworkMod 5.0.2.7
Kernel version: 2.6.35.10
Android version: 4.2.1
Current ROM: GenetICS 9.1.7
Then I downloaded another custom ROM [4.2.1]PACman 19.9.0 [PA][AOKP][CM](seems to be deleted now). Stating thats its some updated version of previous ROM.
Downloaded through XDA app and then opened it directly with ROM Manager to install it.
But unfortunately something went wrong and my phone got stuck on boot logo i.e. LG. :silly:
Then I tried to repair it with KDZ updater using V20c-00 firmware. Everything worked fine. I rooted it through SuperOne click and installed CWM recovery through ROM Manager. :victory:
Till then everything was looking under control.
After that I tried to flash another ROM through CWM Recovery, but again i got stuck on Boot Logo. I tried to repair it once again with KDZ updater as I did it previously, but everytime KDZ updater showed error.
Now my phone is not even responding to anything means not with hard keys combos or something. :crying:
I am not able to find any solution for this, even I searched it a lot.
Please please help me.
Edit: If only LG can help me now, can anyone tell me how much it will cost?

Unfortunately, if you removed the battery after KDZ gives out an error, you have hard-bricked your phone. Only LG can help you now

There is an emergency mode you can attempt, as long as you have the software on your computer to flash factory settings on to your phone.
To access emergency mode, do the following:
1) Take out the battery
2) Have a usb cable already connected to the computer.
3) Hold the power button + volume up + back button AND then connect the usb while holding those buttons
Yellow screen will appear with the words emergency mode in the middle.
At this point, do some forum searching, find some kind of stock image file and LG program to flash stock system on to the phone.
*there is also a forum post somewhere here that I learnt this stuff off of...see if you can find it

I have not had any luck with KDZ or LGMDP with a device stuck in Emergency Mode. I have two P506's that are stuck in Emergency Mode, thanks to KDZ. I have tried every fix I can find here and on several other forums with no luck. I don't want to discourage you, but don't get your hopes up either.
I know this is OT, but...
This is the kind of stuff that we like to see from New Members here at XDA. This is the right way to get your 10 posts. Keep it up

I remember being successful with the LGMDP in emergency Mode with the P500, even though the stock rom that i used didnt quite work with the phone it got me past the boot logo and gave me access back into my recovery. Once you can at least get into the recovery you are golden (for the most part).
OT:
Thanks shinobi. I've been lurking xda for a while now since i got the p500, just recently i really wanted to post in rashed's thread for issues/bugs i found with the cm10.1 rom

No luck to me guys. As I already mentioned that there is no response from phone, not even emergency mode.
Now I tried with even JTAG still no luck.
Went to LG day before yesterday as that was the only hope. But unfortunately my phone is out of warranty and the cost of motherboard is almost equal to the cost of phone itself.
So, that means I have no other option besides keeping it with me as a precious piece of brick.
Thanks to KDZ_Updater.

Cost of motherboard from LG was 8800/- Indian Rupees. And the total cost of phone was 9999/- Indian Rupees.
But I got it repaired in 1800/- Indian Rupees with JTAG. Thanks to a local mobile repair shop.
But I am afraid that this service may not be available in your country.

I am also from India buddy. But I don't think so I could fund jtag in my city.
What is your location?

lg phoenix p505 softbrick fix
had an lg phoenix that kept giving status 7 errors when I tried to flash in recovery, failures in fastboot, and normal boot just went to black screen
Then I found "how-to-fix-lg-phoenix-fastboot-issues" a page that has working KDZ instructions (after a fashion), now it boots to an ugly fuzzy blue bad driver ancient version of android, but hey, it's alive again!
I would post the link, but spam filter prevents it. it was over at lg-phones dot org.

help
I am having same problem.
Can you tell me contact of mobile of repair shop

search web for OCTOPUSBOX or MEDUSABOX, this are sites for JTAG sales but they offer software for free, maybe you will have luck
or bring it to repair shop, it will cost you around 20$

Could you pls tell me if this procedure helps in my situation?

Hi a_loo!
I Have a LG P500 2.3.3 V20e.
I rooted it today without any problem. Loaded ROM manager, flashed ClockworkMod recovery.
Then I downloaded from Cyanogen cm-7.2.0-p500.zip and placed it on the SD card.
And from ROM manager I did an "install ROM from SD card."
It worked for a while the it froze with a cyanogenmod 7 image. None of the controls & buttons and working.
I'm rather new and trying not to panic.
I'd really appreciate your assistance.

Bricked Lg P500
I hard bricked my LG P500 today. It seems there is no hope... No life at all. Oh well... Life sucks I'm in South Africa and don't want to spend money on older phone. I probably did something wrong with LG KDZ, trying to flash stock ROM.

Ugh guys I'm having the same issues my tablet won't go pass Samsung Galaxy note 10.1 splash screen and can't stay on twrp recovery with out rebooting again. I tried to reflash twrp tar and stock firmware but it always fails and then my PC would say my USB driver or port is unrecognizable or malfunction so I bought another USB charging wire and tried it today and still get the same issues I hope someone can help me and us out asap!!

same here
Hi guys!
same here! my note was charging and I've found it stucked in samsung logo without any reason. I've tried to install almost every version available of stock rom also from different country but no way. I can install also custom recovery but unfortunately I don't have any custom rom to try to install in my sd card. At the current time I really thinking to move to new note 10.1 2014...I'm afraid is some kinda hardware malfunctions. Any update from you guys with same issue?

Wow now I'm really start to think it is a Samsung and hardware issue I think these tablets weren't made to be usable for more than 2 years smh is anyone else with this issue running lollipop roms? Jc

The same here, My friend just conntect me, that SAMSUNG does not want to cover charges, due to bootloader says SYSTEM STATUS: custom.
And he never did anything with his tablet.
He got angry and Samsung check the hardware and they find that some chip is broken. But still don't want to fix it due to custom issue.

If you don't have a custom rom, now may be a good time to consider it. If you do, just wipe it completely and reflash it. (Assuming you have a custom recovery --->) If you dont have a rom in your internal, use a USB OTG cable, a computer to download a rom, and a flash drive to hold the rom and use along with the OTG cable Or use a computer along with the Samsung USB drivers to manually toss in a rom via custom recovery.

I sideloaded rom again i tried everything only to find out I did factory reset and everything was good to go thanx alot guys

No LG uses adb and or terminal script. Odin is made for flashing alot of phones at once or a rookies one phone. adb and term is for everything else. learn your code!

I followed that guide (both the original and the one-click version that was posted a few pages in), and neither worked on my LG Risio (from Cricket Wireless). It didn't brick the phone, though. In both cases it just stopped in Download Mode on the phone where it said a new firmware was being installed. The progress stayed at 0% and never moved, and the root script in the command line on my PC just waited indefinitely. The phone was just fine afterwards, like nothing was even changed.
Does anyone know a root method that works for this phone?

I also recently bricked my lg risio. when i turn it on it shows the LG logo and say security error and then shuts down. i tried putting it download mode. My computer detects it but will not allow me access to what is on the phone. I gave up and tried to factory reset it, only to see the same error screen. I rooted and installed mods on my old HTC before, but have since forgotten this lengthy process. Someone please help. Thankyou

Hello, and welcome to XDA!
I see you have made it to the location I was going to suggest:
http://forum.xda-developers.com/showpost.php?p=63315776&postcount=12473
Unfortunately it is getting buried fast. I looked at that post as well. If you cannot authorize yourself to mount system and push the right file back via stock recovery (something that you can rarely do anyway), sadly you have too few options.
Only thing you can do is try to find a fastboot image to reflash system, if your device supports fastboot that is (alternatively, if you have download mode, an image for that). But for a rare device, you would end up having to deal with the manufacturer anyway, so your best bet may be getting it repaired by them.
Sorry, but I hope that helps.
