Problem with Amon_Ra recovery

I have a Vodafone Nexus ONE rooted (with this procedure) but NOT unlocked. With device in fastboot mode, I tried flashing the recovery but I get always the same error "FAILED remote: signature verify fail". I would to flash a custom ROM like the Modaco R22 or Cyanogen, I tried also to rename the Modaco R22 (update.zip) and I put this file "update.zip" to my SD card but I cannot flash (the file not pass the verify)...please HELP ME

I believe fastboot only works with unlocked bootloader
Try ROM Manager on Market

If you didnt unlock your bootloader then you cant use fastboot. You either have to user Rom Manager or flash_image.

How can I use flash_image?

4th result, "Recovery" section.

Nexus Wiki updated, now it includes flashing the recovery via flash_image. You can look there.

[Q] Stuck at Service Provider Splash Screen, and CWM recovery is broken

I have the p880g model, I have rooted the phone and tried flashing CWM onto it.
Now, when I try to boot to recovery, I get "ERROR: boot image signation; Critical failure: unable to start kernel"
And when I try to boot regularly, I get stuck on the service provider splash screen (WIND Mobile).
Is there any tool I can use to get out of this? I had USB debugging enabled before this all went downhill

have you unlocked your kernel before you tried flashing cwm?

Do you mean unlocking the bootloader? No I didn't, I found out after the fact that the p880g can't.
I used this method to root it: http://forum.xda-developers.com/showthread.php?t=1886460
And then just tried using ROM Manager to flash CWM and then I tried rebooting into recovery.

Ah, didnt see that you have canadian version. You need unlocked bootloader to flash cwm trough rom manager afaik. What you can do to fix your issue, is reflash kdz file. There is a guide somewhere on the forum.

So it is fixable? I'm not exactly sure what a kdz file is, would you be able to point me to the guide? I'm also worried my phone won't be able to do it because I was on V09b development software, not whatever the release stuff was.

I had this same problem with my P880g, back before I realized CWM doesn't work with that model. I fixed it by re-flashing the V10C KDZ to my phone. However, it was already running V10C, so I don't know how yours will be affected.
The thread on how to flash a KDZ is here: http://forum.xda-developers.com/showthread.php?t=2069723

Flash the kdz file with the kdz flash tool and put mode on emergency
NOT emergency cs that wont do anything

(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:

[Q] "Bricked" Optimus 4X

Hi.
I was trying to flash LiquidSmooth ROM, installed TWRP recovery, formatted /data and /cache to F2FS and installed the rom, an custom kernel by mourta and PA Gapps.
The phone stucked in LiquidSmooth bootlogo. I tried to boot in recovery unsuccessfully (my Vol - key is kinda broken), the command adb reboot recovery didn't work.
After many tries, I could flash the LG Stock rom, the Kdz program didn't finish the process and the phone rebooted, don't know why.
Tried many other times to flash.
To sum up, I could flash the original firmware, the phone is booting up normally and aparently is working properly, the problem is: I still can't go to recovery to restore my old rom. (The adb reboot recovery comand just reboot the phone). So, I can't root it or flash another custom recovery.
I wish you guys can help me. Sorry if I written something wrong or if the text is too long, I haven't finished my English course yet.

Which stock rom have you flashed? I've tried to use fastboot on a V10 rom couple of weeks ago and I coudn't do it. I think that it works just with V20 roms.

I'm using now V20A_00_4.1.2.EURO.
I could acess the recovery (original) but adb sideload doesn't work. It says: "Error: more than one device and emulator."
About fastboot, I've already tried to flash the recovery using this, but it just keep with one message, I guess is waiting phone, or something like that.

I didn't know that error more than one device and emulator. I can't help you on this error.
About Fastboot still waiting phone, that is phone driver's problem. Try to install P880 fastboot drivers and try again.
Try these drivers: http://forum.xda-developers.com/showpost.php?p=38953792&postcount=17

I figued out about the error: "Error: more than one device and emulator."
It's an incompatibility with Bluestacks, after close it, it works, but I had to turn off the phone and couldn't flash.
And about fastboot, I could acess this too (Didn't knew that I needed to be on Bootloader mode). But I can't flash the recovery, it says that my bootloader is locked (using fastboot reboot bootloader).
It isn't, or at least wasn't before it all happen. Using ADB command to reboot in bootloader mode (adb reboot oem-unlock I guess), I can flash the .img of clockwork mod and TWRP without error messages, but I still can't boot into it by adb reboot recovery.
Thanks for trying. Today I could acess Android original recovery by hardware keys and install another recovery and ROM.

I don't really know what happened, did you successfully flashed kdz?
Where did you get it from? Here?: http://lg-phone-firmware.com/index.php?id_mod=15
Try to flash one of these (choose correct one for you)
Than you have to install recovery again.
But before that you can try to wipe /system, /data, /cache and then flash CM11 (I know it works without problems)
And I recommend you these Gapps: http://forum.xda-developers.com/showthread.php?t=2397942

I think you should try with CWM first, get it: http://download2.clockworkmod.com/recoveries/recovery-clockwork-touch-6.0.4.5-p880.img
you can flash it with this app if you are rooted: https://play.google.com/store/apps/details?id=com.cgollner.flashify
then you can download CM11 from here: http://download.cyanogenmod.org/?device=p880
and gapps from last mine post
and then boot to recovery, do factory reset and wipe /system, then flash rom and gapps.
Hope it helps

Crash After Flash OTA Vanir 5.0
I had a similar experience. I was installing OTA latest update of Vanir...not realising that it was 5.0...a screen came up telling me that it needed to flash another recovery...not realising why it needed that, I ignored the request to flash. Of course, I then "bricked" the phone. I was able to install the original JB 4.12 (v20c) back onto the phone but now it won't root. I've tried almost every method in this forum to no avail.:
ADB just gives a message "error: closing" when I use the boot.exe method
o4xr method does nothing
all-in-one method also does nothing
ADB does recognise the device. Drivers are installed. Any help is welcome!

Have you tried to flash a recovery using fastboot? You won't need to root (if you are going to use a custom ROM) and/or it will be easier with a custom recovery

Soft brick after last update.
Hello,
I seem to have a similar problem. I updated a few days ago using Vanir updater. There were no warnings re updating the recovery, just a warning regarding losing root. I checked restore root. The phone rebooted to the bootloader logo, then to a black screen. Now, I can access Cyanogen recovery, SW update mode, abd fastboot mode using buttons and the recovery options. ADB can see the phone only in recovery mode, but not in fastboot or SW update mode. CM recovery has no option to mount USB storage, so my PC cannot see the phone, and I cannot side load a new recovery and flash a new ROM.
Is there any way to use ADB if it cannot see your phone in fastboot or SW mode? Perhaps modify the settings.secure string to enable ADB? ADB can see the phone in recovery mode.
Otherwise I will try flashing a stock ROM via KDZ or LG firmware update tool, the re-root and proceed - but rooting was a major ordeal the first time, so I would like to avoid doing that again.
Thanks in advance.
