You might have comes across some 00:25 files in your firmware where you have a file name-sign alright? Something like this 00:32 Now, this is a signed image. What this means is that if you intend to port a 00:36 custom recovery with your boot image or recovery image or even if you want to flash or 00:42 modify the system image, you can't do that if (since) it has been altered so it's 00:48 a security feature by your OEM to make sure you only flash verified images so before 00:54 you can port a custom recovery with this kind of image, you have to first un- 00:57 sign the image then you can go ahead with modification. Now, to show you how 01:02 works, I first have to show you an attempt of me trying to 01:07 unpack a signed image okay? so you can see the error message you're going to get 01:12 First off, I'm going to copy this recovery image, its a signed 01:18 image so I'm going to try to unpack using Carliv Image tool. I'm going to 01:23 paste it right here. Now this tool requires me to rename to recovery.img so 01:29 I'm going to rename it quickly. OK, so I have my recovery image. Now, I'm going to 01:34 launch the Carliv Image tool. What I'm trying to do is to unpack a signed 01:39 recovery image. I've not yet unsigned it okay? I'm trying to unpack it in its 01:44 State. I'm trying to unpack a recovery image, I select 1. I select Unpack. 01:51 Alright! Great! The system cannot find the batch label specified - ~1. You can see this 01:57 error. Now, this is what you get when you try to unpack a signed image. You're going to get 02:03 the same thing with boot image also so I can just go ahead and close this. I'm 02:10 going to clear this also. You can see it couldn't even 02:18 extract the recovery image. Alright! so that is what you get when you try to unpack 02:25 a signed image so now I'm going to show you how to unsign this recovery image. 02:29 After You unsign, you can then go ahead to unpack using your Carliv Image 02:34 kitchen. Okay so once you have your recovery image, what you want to do is copy it 02:38 and then you go to the FBWin tools. As for the software (tool) we have a 02:43 link on our website. You can check our Forum for the download link for this tool or you check the 02:51 description in this video for the download link. Now, once you have your recovery 02:55 image (of course) You go to the _In folder and You're going to paste it here. Now, one 03:01 mistake people tend to make when trying to use this tool is that they rename this 03:05 to recovery, which is wrong. You try to remove this (-sign) which you shouldn't do it 03:10 should be named recovery-sign okay because that's what this tool is looking 03:14 out for so You leave it that way i.e recovery-sign or boot-sign or system-sign 03:20 whatever it is You're unpacking. Make sure the -sign suffix is appended then 03:28 You go back. Now, You're going to launch this menu.bat, Its a batch file. You're 03:35 going to double-click it. Now, on this menu, You're going to select 1; that is 03:44 FB. You're doing an FB unsign so You select 1 and You tap Enter. Now I'm going 03:53 to select 1 again (FB unpack) so I'm going to select 1; I'm doing an FB 03:58 unpack; that's going to unsign the image. That is done, it says FB recovery image 04:04 unpacked so I'm going to head over to the Unpack folder - _Image and there I have my 04:11 recovery-sign so now I can go ahead to try and 04:15 unpack this using my Carliv Image since it has been unsigned. Now, in Carliv Image, You 04:22 want to paste it right here in recovery-sources or whatever 04:26 tool you want to use to modify Your recovery image. Now, you need to remove 04:32 the -sign suffix since you've unsigned the image now so there's no point having 04:39 the -sign suffix okay? I'm going to save it as recovery.img. Don't forget this is 04:46 an image file. You can come under Properties (.img is an image file). I can close 04:55 this. Press any key to continue. I can close my FB, I'm done unsigning. 05:00 Now to unpack I'm going to go ahead to unpack. Now, I'm going to launch the Carliv Image 05:08 tool so I'll double click that. I'm trying to unpack recovery so I'll select R,
