[Q] LG optimus black p970 completely bricked and dead after security error - Android Q&A, Help & Troubleshooting

I got a LG optimus black p970 running on official ICS 4.0.1(europe ver), and i was preparing to update it to jelly bean 4.2.2 cm10.1.
so, all i have to do the steps i read in a thread of xda developers.
So, i got all the necessary files and tools for it.
So, i rooted my phone. Installed clockworldmod recovery, and after that i restarted in clockworldmod recovery.
But that was my bad luck, i wasn't aware of that boot loader locking in official ICS ROM.
So,the boot loader locked and everytime i start my phone it shows LG security error.
That was less bad, after that i did the blunder.
I connected my phone to pc in s/w upgrading mode using Smart Flash Tool and erased entire AP and AP(user data).
and after that my phone never started again.
No s/w upgrade mode, No security error screen!!
So, i guess i had cleared the ROM memory, and the boot loader too. So, i guess my phone has no software to communicate with hardware.
Wot to do now??
plz help me.. i love my phone so much...
i am sure that the hardware of my phone is not damaged at all. It was running perfect.
Plzz HELP ASAP...!!

Ah okay, cos I looked up the phone and its nothing like P500 lol XD
To root your phone, you can use z4root, iirc rom manager doesn't support p500.

Get into emergency mode by using key combination "back+volume up+power" then connect it with PC and use KDZ to update your firmware bingo and by this I didn't loosed any setting or data. Just the root for which I used zroot

[Q] I tried to install a rom on my LG C800 and it might be bricked.

Ok i recently rooted my LG C800 or Mytouch Q using SuperOneClick which went well. However, When i tried to install a new rom using ROM Manager of the play store i first backed up my current rom and when it reboots its stuck on the boot LG logo. I have tried going into recover mode and it will show the android unboxing but a few seconds later it goes back to the LG logo. I don't want to say its completly bricked as i do get the LG logo, But i have run out of solutions, and any help would be appreciated. Thanks.
rom man

LG myTouch Q (C800) Stuck on LG Logo Fix Solution !
:good::highfive:

A unique problem

it all started when i installed a faulty launcher
my phone's in a boot loop
when i try to slide the key into the lock on the lockscreen, it reboots.
otherwise touch is working fine (emergency call, status bar etc)
but since i can't open the lock, i can't access the home screen and apps and stuff..
obviously i tried recovery, but it doesnt have a factory reset option (strange). the recovery mode only has some phone tests and calibrates
the other hard key combination opens up some black screen with "fastboot mode" written. and that's it.
my phone is gingerbread 2.3.5, unrooted. the company is a less popular and cheap one but it's not china.
long story short, i cant get outta boot loop coz recovery doesnt have factory reset option
plz help!
thanks
i did as you said. but when i erased everything and booted the phone. it's stuck on the manufacturer's logo. it doesnt even reach lock screen now.
fastboot commands are working. i flashed a new recovery, but its not accessing. what should i do?

In recovery, try to wipe cache and dalvik cache. If still, then you need to flash stock ROM

That is because when you ran those commands you wiped the rom on your phone completely so now when it tries to boot it has nothing to boot into. Please give the name of the phone so we can help you more.

**Press the thanks button if I have helped you.
Erasing the user data and cache was good, but erasing boot erases your kernel, just find the one that came with your ROM and as long as its in .img format use fastboot to flash it and all should work great

yo, the prob is, it's a recent phone, but from qmobile
it's qmobile bolt a2 lite. i cant find the stock rom (it was released in 3 july 2013, i believe)
so, can't i install some other ROM that all gingerbread phones support? it has 1 ghz processor, 256 mb ram, and 200 mb internal storage
thanks
i have a 2gb micro sd card as well
Then you have an issue, right now it sounds as you have no kernel maybe if your lucky the manufacture will respond to a request to release the kernel source or have a copy of factory firmware you can download.
Otherwise try to find someone with the same phone and see if they can get you a copy of the kernel
Sent from my Nexus 4 using xda premium
since i can't find the exact stock ROM for this lesser known brand, isn't there some universal gingerbread 2.3.5 stock rom? the manufactureres obviously use a modified version of google's stock gingerbread 2.3.5
It won't work, you can't just flash some generic aosp ROM to your phone, if it were that easy every phone would have tons of ROMs
You need a device tree that contains all the proprietary drivers etc to build from source and just flashing a random kernel or ROM won't do you any good (possibly make things worse)
You need to contact the maker of your phone and request this or find someone who can get you a ROM dump

P769 with v20f getting security error

Hi,
I had my P769(T-mobile) running v20f for a while, everything was fine till I tried to unlock the bootloader yesterday......
I followed the http://forum.xda-developers.com/showthread.php?t=2370835, but was not aware that the bootloader unlock was unsuccessful before I used fastboot to install the cwm recovery. Then.....I got the security error when I tried to reboot the phone.
Now fastboot can connect to the phone and reflash x-loader and uboot with no problem, but I cannot get my phone into s/w upgrade mode no matter what key-combination I try...... of course the LG update tool would connect to the phone neither.....
Anyone could help me fix it? Thanks!

You can try the recovery.img method. If that doesn't work, there is another way in that post.

Take out your battery connect to your pc with battery out...hold volume up and power. you might need to hold it for a few seconds after you see the s/w screen. What version is you phone? It happened to me on 20h.

Need help with bricked Moto E

Hello,
I am new to this Moto E. It's actually a friend's phone and he though that since I have experience when it comes to LG G2 and S II Skyrocket SGH-i727, he decided to ask me to help him unbrick his device.
It's not actually bricked per se. It's actually stuck at the boot. It comes up to optimize the apps and start the android but it never ends. It's always stuck at Starting Android. I was able to get into TWRP recovery but I can't mount the USB. No matter the mode I place it, the usb is never detected. I can't find another way around to fix it. I was thinking about a clean factory reset from TWRP but I'd still like to get around with something.
Since USB is not working, can't get flash stock ROM to downgrade from lollipop 5.1.1 to 4.4.4 (that's pretty much what he wants, once the device is fixed).

No, but he just told me he previously wiped pretty much everything through TWRP... I'll try it when I get to my pc and report back with results.

U need data? if yes there is no way around it, if data not needed, flashing fastboot firmware via Fastboot or flashable zip of Stock ROM or any Custum ROMs via TWRP will boot up the phone, since phone is booting to twrp and bootloader, it can't be said bricked at all, the phone is in safe state, we can do anything if phone boots up to recovery,
