Hi I'm trying to install the " cm-11-20140323-NIGHTLY" rom onto my phone, I've flashed the phone using "SuperOneClick" but now when I try booting with holder power + vol up/ down I'm getting this error mes;
[LGE security] ERROR: boot image signature
[LGE security] 5 seconds after Power is turned off for Battery saving
I'm wondering if anyone can tell me whys it saying this now and how I can get round this as I really want to upgrade as the current stock OS is really laggy for me. Also I can still boot into the phone and use it as normal e.g. calls
Thanks

I'm not going to give you a list of detailed instructions.You'll have to google how to do them yourself.
Connect your phone to PC, open LG mobile support tool and (re)flash latest firmware <---- required since you can't access recovery.
Unlock bootloader
Flash a custom recovery (via clockworkmod if you're rooted)
Wipe /system, /data, /cache
Flash the cm nightly zip
One does not simply flash a ROM with one tap.
Note that these steps will make you lose any data that's inside the internal storage.Which means internal sdcard will be wiped also so you'd better take a backup of your private data first.

no, i wasnt hold enoght!
sorry that was too noob
Edit:
i'm still having problem!
i can't flash a custom rom or recovery my backup, still looping or crash.
when i try to recovery the backup the data partition can't be mount
if you are getting boot loops, make sure you are doing a full wipe and also checking that you have the correct ext3/4 on the phone before installing the rom or loops will happen.
Do you mean the nandroid is what you can't restore??
this is accessed through the sd card in you phone

Error mouting /data/
If i try to recovery my nandroid backup, the data can't be restored and phone crash to start
If i flash a custom rom, i could turn on the phone on but it's crash and turn of.
now i'm trying to use navflash but holding both buttons and connect the phone i cant get the APX anymore.
Please help me!!
If you are using Nvflash I cant help you anymore because I have never used it, Im sure someone else will be able to help you follow up from here, I will check back later see hpw you gettin on.
Did you download the nv drivers and follw everything
•Turn device off, remove battery, plug device in while holding volume up and down - screen will stay black but Windows will add a new 'APX' devices
in this order????

Hello,
After rooting my p880, my phone hangs at boot. Just after the boot sound (*pling* ) the phone is hanging. The boot image is still moving.
Things I tried already:
I followed this thread http://forum.xda-developers.com/showthread.php?t=2069723, which tells to do a kdz update. This is not working, as I am not able to get to the S/W upgrade screen. Instead, when I start the phone using the power button + volume down, i get the Android system recovery menu (3e).
I tried to upload a new (cyanogenmod) rom using adb sideload, but that didn't work, as the file I used was damaged (I will retry with new file).
I also did a factory reset and a cache wipe.
Can someone tell me what is best to do?
Kind regards

you're entering s/w mode wrong. dont press power button. just hold vol down and plug in usb
OOOhhhh noooosss....... That's kind of stupid .
Thanks!
was with the original rom lg. and then went instalr the recovery of the cyanogen rom manager app, and then hung up the phone and now the message appears in red at the top of the screen
"Critical Failure: Unable to start Kernel.
Unrecoverable bootloader error (0x00000002)"
and I can not get into download mode to install the original rom again.
and now what do I do? I lost my phone?
you flashed cwm without unlocking your bootloader. re-flash latest jellybean kdz file for your phone using http://forum.xda-developers.com/showthread.php?t=2069723, then read some more about unlocking bootloader, and then start again.

but now I am unable to get into download mode on the phone. is
" Now just hold down vol - key ( hold hold hold dont release !!!! ) and plug the USB cable until you get screen like this :-"
he does not. whenever I do this it only vibrates strong and goes to the screen with the error message. I do not know why that. remember one time it happened to me already but can not remember how I resolved it is possible to even lose the download mode?
Its not possible afaik. Are you sure you are holding only vol - key and plugging in? Dont hold power key!
yes, I'm almost the whole day trying to get into download mode by pressing volume down + connecting the usb. and whenever it vibrates strong and hangs on lg logo. tried to volume up + usb connect. and no download mode. I'm going crazy with this phone. otherwise hesitate to hard reset? or other shortcut to download mode?

hard reset wont help you, as far as i know, you somehow need to enter s/w upgrade screen. did you try it with battery out?
he battery of the same error, and no battery it does nothing, or vibrate, or flash screen, nothing happens
Will I not be able to see my optimus running again? :crying:
it is not possible to load the kernel, what could I do?

Hi Raphael20 and everyone else,
Did you manage to figure out a solution to this? I have the same issue, i.e. cannot start my phone by holding the power button. Not even when people suggest to get to the S/W Update screen by holding the Volume down + plug into the computer.
I got to this error when I tried to do a factory reset. I installed the ClockworkMod Recovery. Then the factory reset via Volume up + Power button gave me the "Critical Failure: Unable to start Kernel" error. I somehow managed to get access to my phone by holding the Volume down + plug into the computer. Then tried to do a factory reset via the system settings of my phone. My phone restarted and then gave me the "Critical Failure: Unable to start Kernel" screen of death! Now Volume down + plug into the computer gives me the "Critical Failure: Unable to start Kernel", no matter whether I have restarted my computer and I have tried another computer. It seems that the bootloader is wrecked.
Does anyone have any suggestions?
Thanks!
Hi guys, first time posting here, sorry if a question like this has already been asked but I've looked around and haven't managed to solve my problem yet.
So I have rooted my Samsung Galaxy Mini II (GT-S6500T) and used Odin 3.07 to install ClockworkMod 6.0.3.2 onto it; I then booted it into recovery mode and installed ZIP from SD card, selected CyanogenMod 10.2 ("cm-10.2-20131202-UNOFFICIAL-jenad.zip"), followed instructions etc. installed Google Apps and all that.
Now, when I selected to start up the phone again, it just gets stuck in the Cyanogenmod boot screen, the blue arrow just circles around on and on (I understand that it usually takes a long time but I don't think it's meant to take over half an hour... also, every now and then I notice it kind of makes a low vibrate sound?).
I've read that to fix it you can reboot it into recovery mode and reflash it but the problem is I can't even get into the recovery mode. If I force the phone off (e.g. by removing battery) and hold Vol Up + Vol Down + Home + Power to boot recovery mode, nothing happens. If I just hold Power it starts up and goes straight into boot sequence.
I do have a backup of my previous settings and all that saved - one saved on my external SD card and the same file saved on my computer, so if I can somehow load that back it would be great I guess.

I mentioned earlier I cannot enter recovery mode. When I hold the button combination to go into it, nothing happens.
Earlier I managed to get into download mode (Vol Down + Home + Power) and I reflashed a stock firmware, but now my phone is stuck in a boot loop, it just shows the Samsung screen and vibrates every now and then. I still cannot access recovery mode.
Managed to fix the problem but thanks for the help anyway. Followed one of the solutions here and removed everything, held power for 1 min, plugged my phone into the computer and managed to get into recovery mode. From there I did full wipe, wipe cache, wipe Dalvik cache, format /system (probably only necessary to do full wipe but I dunno), then restarted into download mode and used Odin to reflash stock rom, then reloaded recovery mode and reloaded my backup.
edit: My question now is, I'm not sure what I've done wrong in the process of installing Cyanogenmod to screw up this badly. Is it absolutely necessary to format /system before installing it? I did do full wipe, cache and Dalvik cache and mounted /system prior to rebooting and loading Cyanogenmod.
what i do > install rom > reboot > install google apps .. I had this problem aswell a while ago. what also can be the problem is when u don't format correctly..

Have You as well was unable to go into recovery mode and stuck on bootloop ? One thing I can do is to use Odin, tried to flash some stock firmware with no result. Still no acces to recovery and still Samsung logo loop. I searched, read many topics but nothing helped. Is there something except Riff Jig that could be done ? Thanks for response
-Flash stock rom via Odin
-Flash cwm via Odin
-Pull out battery
-Connect phone to pc (without battery)
-Wait until screen turns on
-Hold recovery combo keys until samsung logo shows (home+volup +voldown +power)
-put battery back quickly
-You should be in recovery now :wipe data, cache, dalvik cache
-Reboot.
I was in similar situation, if not identical. This worked for me. Good luck.
Edit: I didn't see you fixed it already. Ignore the post.

I have been tearing my hair out for like six straight hours now... so first I started with completely stock 12B.
Here is what I did.
1) Root using ioroot method
2) Install TWRP using FreeGee (which I'm now reading caused this entire mess god damnit)
3) Go into TWRP and format data to get ready to flash stock rooted debloat
4) Accidentally format sdcard so I have to get my rom zip back onto my phone
5) adb push keeps failing because rom file is so big so i flash a smaller size AOSP rom which boots
6) MTP transfer my stock rom zip file to my phone
7) go back to TWRP, wipe everything again (except sdcard obviously) and flash the stock rom
8) stock rom hangs at boot logo for ~20 minutes so i force restart, try again three times
9) go back into TWRP, TWRP starts not flashing things and telling me I have a partition error
10) TWRP isn't working for me anymore so I try a revert back to stock (verizon .tot) method posted here using LG Flash Tool
11) Fails twice
12) Phone has no more TWRP and only download mode
My questions
1) Is this phone totally screwed because it is the replacement I just got for my old one and I can't even unroot it to get another replacement (using manufacturer warranty, no verizon warranty)
2) Is there a way to get back to clean slate stock or even flash anything (TWRP, etc.) with only download mode available
I cannot function without my phone and I am very stressed right now somebody please help
EDIT: tried doing reset to stock KDZ method and it passed but when i reboot the phone i'm still stuck with only download mode, no recovery, and nothing past the LG logo. still the same....
turn on phone, see LG logo, immediately see download mode. now at least the LG logo doesn't hang but now it's the download mode,.

1) Probably not
2) Yes, using the method you've attempted already. Make sure you validate your download and follow all the steps carefully in the guide.

I've repeated carefully with multiple downloads, but I deduce I have the following problems.
1) Partition error with TWRP caused by FreeGee and probably deleting my /sdcard/ partition or something idk
2) My attempts at returning to stock have removed TWRP in place of download mode for some reason so I can't do recovery
3) Something is wrong with download mode because it's not being effective in the .tot or .kdz return to stock methods
4) I don't even know what's going on anymore I'll sleep on it and come back tomorrow
thanks for the quick response. I think I'll just see if i can pin this on the replacement guys and get a replacement.

Then the flash tool didn't take. I've used it three times now and after the flash says its successful, you take the USB out of the phone and use the hardware keys to factory reset.
Instead of going to twrp as it usually does, it actually does the factory reset. If you don't do that then it bootloops till you do. The flash tool doesn't remove everything to make it factory stock.

I doesn't seem like you're pressing the right button combo to get into the Factory hard reset menu.
Do this:
1) Power the phone off completely (press and hold the power button until the phone shuts off).
2) Press and hold the power and volume down buttons at the same time.
3) When the LG logo comes up on the screen, let go of the power and volume down buttons, then press the power and volume down buttons at the same time again until the Factory hard reset menu comes on the screen.
4) Once in the Factory hard reset menu, press the power button twice to factory reset the phone.
If you already knew this, then I apologize.

Yeah, when I do that I get the download mode "firmware update" screen. previously it would lead to TWRP, but now it leads to firmware update screen.
ty
New update: I finally got 11A .tot to flash, but booting it was really unstable, kept rebooting / blank screen of death like every time I tried to get in. Finally became slightly more stable when I took the SIM card out, used WiFi to download 12B update using OTA. Installed OTA and now it's hanging at the "Updating software 2/2" page at 35% (the page with the beautiful picture of the lush green grass and the blue sky). I'm just going to leave it for a night plugged into the wall and see where it goes, maybe it's frozen, maybe it's not.
Probably it is. In which case I'll probably have to force reboot and I'll wake up to a host of new problems.
