[Q] my 4x HD won't boot after flashing insecure boot.img - LG Optimus 4X HD

OK I used this tool found herehttp://forum.xda-developers.com/showthread.php?t=2230934 to unlock and root my optimus 4x, it successfully flashed superuser but wouldnt unlock my boot loader, it brought up the screen to continue to unlock and press volume up but it got stuck on that screen for 45 minutes , I flashed twrp recovery but it wouldnt boot to recovery so I reflashed stock recovery,so I thought it would be a good idea to flash an insecure boot image,now my phone won't boot to recovery or boot at all , I just get error;boot image signature,any ideas guys,I only have the phone a day.

You have to unlock your bootloader before flashing recovery or unsecure boot. Look here: http://forum.xda-developers.com/showthread.php?t=2224020

(Please help) Optimus black shows Security error screen when boot

Hi guys, my friend just bricked his LG Optimus black, by trying to reach recovery mode through Rom manager...
When booting, the security error screen flashes and it turns back off.
I've tried to reach recovery/download mode, by trying several button combinations found on the internet, but none of them seems to work, I get the same security error screen (even when the phone is connected to PC).
Can you guys please help, I have zero experience with this phone
Your friend's phone shows security error because he flashed recovery while he was running a v30x stock rom.
With the update to official ICS, the bootloader changed and if you want to keep stock ICS with recovery you need to flash an unlocked bootloader following this guide http://forum.xda-developers.com/showthread.php?t=2160394.
You could also try using SmartFlash Tool to flash this ROM that already includes a recovery, but, if you flash it, you'll have a gingerbread ROM with an old bootloader and a recovery that can be used to flash CyanogenMod based ROMs.

Thanks, I finally managed to access Download mode and flash stock firmware, and I also flashed the unlocked bootloader, using the exe file...
But I still have a problem...
I still can't access CWM. When pressing the combination in the post you linked, it just shows me a screen, writing recovery mode, and it does nothing.
Didn't the exe file install CWM?
Is it safe to install it with Smart Flash Tool now?
Can you boot to stock ROM? If yes, is his phone rooted?

I can boot to stock ROM, and yeah I rooted it with Unlock Root after installing the unlocked bootloader.
Download terminal emulator from play store, download recovery.img from here and place it in the root of his sdcard.
Open terminal emulator, type su, press enter, type dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p4 and you should have finished! :highfive:

Ok. let me try.
After unlocked bootloader it will be display that unlocked boot logo for ever until you flash this on custom recovery:
LogoFixWarningv2.zip
But for that you need custon recovery.
you can use this:
twrp-2.8.6.0-titan.img
to flash custo recovery use this mfastboot
mfastboot-v2.zip
with this command with device on bootloader screen
mfastboot.exe flash recovery ''recovery name''
change the '' '' for the recovery name ex.
mfastboot.exe flash recovery twrp-2.8.6.0-titan.img
To do all that you need to re unlocked your bootloader if you re locked it...
so do the command
mfastboot.exe oem unlock UNIQUE_KEY
Where instead of 'UNIQUE_KEY' you type in your own 20-character key that Motorola sent you via email.
:good:
i managed to flash the recovery but how do i boot into it now?thanks also for the help but when i boot to recovery through bootloader it just shows a black screen :/

To boot to recovery you need to be in the bootloader screen.
press the down volume key to move the option to recovery and press the up volume key to enter recovery.
It will boot to recovery, is very fast to boot to recovery... But remember boot loader need to be ''device UNLOCKED Status code: 3''
That same recovery that i share is the recovery on my device so it work's. And is the last version available.
:good:
WOW finally!u are like a god to me right now i have been trying for days to reach the recovery menu!!!i just unlocked bootloader and installed the recovery but then it got replaced by the stock cause i booted into android and i couldnt get it to open then i just reflashed it and BOOM! AWESOMENESS!!!!!I AM SO HAPPY MAN!
nice :good: i'm glad that work... thanks.

You have flashed a recovery image to your boot partition, so it always boots to recovery. You need to flash a boot image to the boot partition.
But why do you want recovery if you won't flash anything to your phone?
By flashing recovery, you are doing exactly that anyway.
You have an unlocked bootloader, so you may as well flash an advanced stock kernel. It is stock kernel with twrp built into the boot.img. Check android development section.
thank you
since i know that i can't boot recovery without flashing, i have no other option as to flash.
can't i flash it to FOTA partition?
i have 10.7.A.0.222 firmware and need root access but like to do it manually
You can't boot directly to FOTA on XZ. Need modified boot.img or flash twrp to boot (like you did before). Then while in TWRP, flash Supersu.zip to get root. Afterwards flash kernel only in flashtool to get stock boot back

Is your bootloader unlocked?

Only able to access fastboot, boot and recovery mode both fail.

Hello Guys,
Yesterday I tried to root my Moto 2g.
Unlocked it's bootloader,Installed Twrp and installed supersu. Also downloaded a custom mod(the most famous one I guess) and installed it,only to find out that the phone would no longer boot
but keep looping on the unlocked bootloader warning screen.While thinking that I had downloaded a non-compatible mod I Installed another one.After that,booting the phone would Instantly
take me to the recovery mode and keep looping the Teamwin logo.
I decided not to mess anymore with it and reinstall the stock firmware for moto 2g. After Installing it the Motorola logo comes up and then I am taken to the fastboot screen once again with the error saying:
"Fastboot reason,Fell through from boot recovery mode".Tried to flash CWM to see If I could get into recovery mode from there but I would get CWM logo loops exactly the same way they appeared with Teamwin logo.
Seems like phone is dead to me but still have a bit of hope,although the only place I can get is fastboot.
Edit:I tried to fastboot flash boot boot.img the stock image and I got and error saying that boot.img(10mb) exceeded the partition limit

If so, u should have boot first Just After unlocking the bootloader before Flashing any MODs

Ok let me explain the situation better.Last night I used a stock firmware I found and flashed it.When I tried to boot I would see motorola logo once
fore boot mode,Then it would go to recovery so I would see it for a second time and then I would see teamwin logo looping so the phone was not
able to get into recovery mode but only into bootloader.
After That I flashed CWM and the same thing would happen with CWM logo looping now in recovery mode.
Today I woke up and flashed CWM again,and for some reason I could get into CWM and use it normally
So what I did is Installed Supersu and a mod for my xt1068 and tried to boot but phone stuck in the same endless loop again and I also cant get
into CWM again as its logo keeps flashing instead of taking me into the menu.
I believe there is an error with my data folder or partition or w/e.
Most of all I want to be able to get into CWM again

So u are not able to get into Recovery
And u can get to Fast boot Mode?
If yes Flash TWRP latest(3..1.0-0)
Boot into TWRP
Reset or Install any Custom ROM like LiniageOS or AOSP
I think it's the problem with SuperSU?
Which MOD did u install?

Thanks for the replies,I managed to solve the problem and install Cyanogenmod.I guess everything came up to this:
After the first time I installed twrp I decided to wipe my data folder but somehow it was deleted and the partition became raw type which caused
all the bootlooping problems.
Using CWM I was able to get into recovery mode and then I chose to format my data folder and sd card(as ext4 I guess) and the data folder was
recreated.
After that I normally flashed Cyanogenmod and device booted just fine
