Disable check signature on recovery mod e3

---

Hello,

I have a chinese console with android 2.1 (the Yinlips G18) and the recovery mod e3. I want to install an update.zip but I have this message : "E: Signature verification failed". So I want to disable the signature verification. But how I can do that safely (Modding or replace this recovery with cwm) ?

PS : Sorry for my english, I'm french.

Thanks for your help.

You cannot disable this because your bootloader is locked. You have to sign the update.zip then install it. Here in XDA you can find a program who sign files!
Motorola is doing this in the devices, and it's pretty difficult install update.zip!

Thanks for your reply, I understand better.

I have build an update.zip from an other. I've signed my zip witgh autosign or Sign++ but this don't work.

Where is the problem ?

Maybe the problem is how you signed it. Try changing the sign using another program. What are you going to flash, anyway?

With a locked bootloader the only update zips that will work are ones signed by your phones OEM. To flash anything else you will need a modded recovery image and unlocked bootloader.

Thats the thing You cant sign it. The only sig that it will accept is one from your OEM. You will need to make or find a custom recovery img for your device. That is one of the issues with getting a off brand device not alot of people here work on China based devices due to them not being available everywhere and some of them not having official Android versions

I have seen the post of snakeman before but I'm a beginner and I don't see what on this post can to hep me (sorry for my ignorance).

I'have found this (gp32spain bitrider G18) :

"Añado aplicación para realizar el volcado del sistema para aquellos que les llegue la consola con una versión de firmware superior a la disponible y quieran colaborar:

Instrucciones:

- Rootea la consola
- Instala la aplicación adjunta
- Ejecuta la aplicación y espera a que termine, puede llevar unos minutos.
- Si todo ha ido bien terminará con un mensaje: "Success!!!" y los archivos estarán en la carpeta FirmwareDump de la micro-SD.
- Copia la carpeta FirmwareDump de la micro-SD al PC, comprímela y házmela llegar.

La carpeta contiene dos archivos "boot.img" (el kernel) y "system.tar" (el resto del S.O.).

La aplicación es bastante simple y no está muy pulida en cuanto a lo que a interfaz de usuario se refiere."

I have recovered boot.img and system.tar . I can to do something with that ?


EDIT : How can I make a custom recovery img ?

There is a way to find the official keys with an other sign method ?
