[Q] Secure Booting Error problem ("Device UnLock!!, so Boot Success!!") - LG Optimus G Pro

Hey everyone. Out of pure desperation, this is my first post here because I'm absolutely at a loss of what to do.
So I first rooted my Optimus G Pro with Super One Click, then used FreeGee to get CWM Recovery on there, which I heard unlocks the bootloader, too. I then tried to flash the CyanogenMod ROM on this forum, and didn't have any "errors" during install. After this, however, when I rebooted, I was simply met with the "Secure Booting Error: Device UnLock!! so Boot Success!!" message.
I can access CWM-based Recovery 6.0.3.3 still, but can't find a way to put files onto my SD card now. Any ideas? Can I fix this error? Should I just reinstall stock? If so, where do I get it, and how can I put it onto my SD card?
I'd really appreciate any help, guys. Also, if you for sure have a way to get CWMRecovery to boot up, I seem to only get it going with luck.
Thanks for any help or input, guys. I'm pretty distraught, especially since this phone is so new.

Try to wipe/factory reset/cache/dalvik and if it doesnt boot and you didnt make any backup from stock rom before cm installation you have to reinstall the stock firmware again

So I've decided I'm okay with going back to Stock Rom for now. If I can't access the phone via USB (at least from my computer) what choices do I have? I'm looking in sideloading. Does that seem pretty alright?

You are supposed to get that secure boot error message when u unlock bootloader and when u flash cm10.1 or any 4.2 rom your SD card becomes a file called 0. It can be accessed in a file manager that has root access and it will b in a mnt. folder. It takes a while for cm to boot so after the lg logo it should b around 5 minutes of black screen.

Okay, so I guess I'm not worried about the boot error message anymore, but I can't seem to get anything to happen. I get the LG logo with the error message, then nothing. I waited about 8 minutes before to no luck. I DID see the CyanogenMod logo once or twice, but it just stalled and didn't do anything. I'm thinking it's a battery thing, but in this state, I can't seem to find a way to charge it.
I did a few different methods of trying to reinstall stock rom (since I'm thinkin now I'll just wait until an official release of CM is available). For the LG Flash Tools version, it's saying my BIN doesn't match with my DLL or something (I'll be more specific when I have a chance). When I do the R&D Test Tool, it says my battery doesn't have enough charge to go through with the update (which is what's making me think my battery is gone).
Right now I have my phone plugged into a wall outlet with CWMRecovery open, because I read somewhere that you can charge your phone that way if you need to.
I'm kind of at a loss, guys. Any specific ideas or help?

I understand that this error is normal as it should be: http://forum.xda-developers.com/showpost.php?p=45094932&postcount=148

faced the same issue a while back.......... I had to flash back to stock, reroot and install lokified cwm from freegee. But while doing so, do not disable LG security. After that, I can access recovery normally. BYW, this happened when I flashed 4.3 based rom from a non-loki supported cwm.
Hope this helps...... BTW I am using E988.

Hello,
I have the same problem with the optimus f120k
When I attempt to reboot show the message:
secure booting error
cause: boot certification verify
Can I recover the phone?
Can I access the phone?
I'd really appreciate any help
Tanks

Hi I rooted the phone, then install the FreeGee , and always start the phone in recovery mode! what can I do for that start with the system normally and not the recovery???
Thank you!

I suspect that FreeGee does something wrong to our devices!
I tried EVRYTHING but still stuck on CWM
E988

same error on F240K E988

Is there any solution for that?

You must flash it back with lg flashtool

That message only says that the bootloader is "unlocked." If it didn't say Boot Success then you'd have a problem. After a fresh flash it takes a few minutes before the phone is usable.

Yes, after the bootloop problem, I have flashed back with lg flashtool, but i hope will be a solution for that bootloop problem...
LG E-989

reflashing a recovery fixed my recovery bootloop
was using philz_touch_6.15.4-e980 when this happened and I'm not sure if reflashing the same recovery would have fixed it
I had TWRP-2.6.1.0-E980-LOKIFIED-E986HACKED.zip on sd from here so I flashed it and restarted recovery again but after that it booted normally

For real? DO NONE OF YOU KNOW HOW TO SEARCH?!?!??!?!? There are 2 threads I created, one in general. One in Q&A. Read through those. There was no need for you to flash back to complete stock. I guess that's what y'all get for not searching (@@)

Huawei 8120 refuse to boot up bootloader not working to.

So i was using slyking241 rom for a wile but then i decided to go back to stock rom i followed this:http://forum.xda-developers.com/showthread.php?t=1011527 tutorial step by step to reset my phone but when it starts updating it says unpacking and then updating gives na error i tried it multiple time but no luck then i though that i should go back to the 2.3.7 sly rom but it refused to boot up just get the cwm boot screen and endless reboots so i wiped data , cache,dalvik,battery stats but it still wont boot i reflashed the rom still doesnt boot tried 2.2 rom still doesn't boot..(cant past the sand clock icon) the recovery works fine i thought of istalling new recovery but i cant get into bootloader please help.
Thank You

The U8120 hasn't a real bootloader.
You hould flash the phone again!
And I mean fullflash (root the phone,install AmonRA...)
Just like you want to root it.
In my Thread (just click U8120 in signature) you can download the stock rom!
P.S.on't change the recovery after rooting!
Eclair works only with AmonRA
!FORMAT YOUR SDCARD BEFORE TRYING THIS!

Unable to install CWM Recovery!

I am rooted with stock Android 4.0.3. I have ROM Manager and attempted to apply a new font, Chococooky. I was able to download and the installation process began, the phone powered off for 1-2 secs and turned on into an image with a sync sign and a loading bar, it stopped about 80% of the way full and then a new image appeared with a phone and an exclamation point: ! Root Checker was used to ensure proper root. I am properly rooted. Permissions were granted as well.
What's going on here?

Clockwork is about dead now isn't it? Follow the above advice, and if you can't do commands use the toolkit, just not the latest version I believe it has ADB derp's. Put the TWRP image in the recovery folder of the toolkit, then flash away!:good:

Clockworkmod failure
HTC One V Primo C
Rooted this phone awhile ago, no problems.
Decided I wanted to flash Clockwork Mod to my phone.
I'm running Icecream Sandwhich.
Went through steps.
Got all excited.
Went to Reboot Recovery.
HTC splashscreen stays frozen.
From what i've read this is called a bootloop.
I want to know how to fix this problem.
Do I need to restore to factory settings and start over?
I'm at a loss. I've tried to re-do the steps a gillion times.
Went i'm in bootloader mode, it says .img cannot be read.
I've worked on it most of last night and most of today.
Still cannot obtain problem.
Deeply frustrated. Please help!

try to flash twrp 2.2.2 CWM seems not to work well on these phones

Any hope for 3rd party rom to F240s/l/k users?

There are recovery available for F240 users, rom for E980 is exploding. I am very sad to see myself being left in the dark....I almost want to flash the E980 into my F240, let it work or die, once and for all....
actually users have reported using cm 10.1 and 10.2 roms on f240 models.... also AOSP roms for e980 don't flash a modem so you don't even have to do that..... but some people have suggested to wipe internal memory or internal sd card when moving from stock to aosp roms..... happy flashing.... don't forget to share your experience
@smaybe you might have some advice to share
Sent from my LG-F240K using xda app-developers app
OK, i did not flash the recovery because i did not think there are any rom out there to try.
Since the Roms for e980 seems working with F240, now the recovery is flashed into my phone. So far, doing back up in CWM, and downloading the PAC rom for testing.....
wish me luck....if I dont come back again...that just means my F240s bricked....:angel:

my phone cannot boot into rom or recovery....just a LG logo after pressing the power button...
hold volume down and power together will have a message of factory hard reset come up. I hit the "power" for factory hard reset, but still, nothing happen.

That is strange you should see a secure boot error after freegee worked
Secure boot error
Cause device unlock so boot success
have you tried the button combination to get into recovery?? if that fails your option maybe to download LG flashtool connect your device in download mode and flash stock rom and then start again
what I suspect is that freegee didn't install properly

its normal to get this message when you try to boot into twrp http://i42.tinypic.com/5n7psj.jpg, it just means that loki is working. What do you mean your tablet doesnt boot anymore? You d better ask for help in twrp's thread, drgravy who ported twrp for gpad is very helpful.
No I have not tried to factory reset the device. I don't even know how to do it, i guess through LG PC TOOL. I would love to avoid becasue of some stored photos.
"Doesn't boot" - it means that after turning on, apears LG logo, and then the ifno about this error and it automaticly turns to recovery.
I assume you have non stock recovery. Do a search the in the forum. It is finicky and took me 3 tries but then was able to boot into recovery. From there did a factory reset and was able to boot up. Still got that same message during the first 3 seconds of the boot screen but then it switched to the Google kit Kat screen and boot completed.

Did you flash a custom rom? Also which version of twrp did you install? 2.6.3.0 doesnt work normally, you need 2.6.3.1 or 2.6.3.2.To flash back to stock there are 2 ways, easiest is the lg mobile support tool (http://forum.xda-developers.com/showthread.php?t=2590185), you cant flash the stock from recovery or adb atm.

If we have a twrp backup can we flash back to stock ? I usually make nandroids right after I root my device.

I havent used this feature in the gpad but it should work if you ever need to restore your tablet to a previous state. Take in mind though that this backup isnt stock as you had rooted your tablet in order to install twrp. To flash back to full stock (recovery, rom and even kernel if you had changed it) you have to use a method like lg mobile support tool.

[Q] There is no way to get to recovery mode

So, I got an used Xperia ZL. The person who sold me this said he installed an international firmware, 4.3 and after installing SuperSU I noticed the device is rooted (and bootloader is locked). Now, I want to install a custom ROM but I cannot access Recovery mode! When phone starts there is no LED, pressing volume up does nothing, I installed Quick Boot, clicked restart on recovery but it does nothing. I even tried ADB boot recovery but the phone just restarts normally. What can I do?? I'm going crazy with this phone. Thanks for the help!

When phone starts there is no LED, pressing volume up does nothing, I installed Quick Boot, clicked restart on recovery but it does nothing. I even tried ADB boot recovery but the phone just restarts normally. What can I do?? I'm going crazy with this phone. Thanks for the help!

Ah, thank you both. I got what the problem was, 'cause I installed recovery, then a new rom and lost recovery again xD Now i know, recovery needs to be installed every time something else is flashed. Thanks!
