downgrading to 4.1

[supermiss]

Hi guys.
I'm trying to down grade my SGH-I317 rom from 4.3 to 4.1 in order to unlock it. I've done the system wipe and cleared cache ,but when I attempt to flash the 4.1 rom in recovery it gives the error message "e signature verification failed".

Does this indicate that I need to flash a different rom like Cynogen or Clockwork BEFORE trying to flash 4.1? Or is there something else I've skipped over that could cause the failure? Or is it the file itself that's not compatible?

4.3 rom is stock JB

I'm accessing everything from external SD card not via USB.

Which guide are you following? Typically the revert to 4,1.x is done with an Odin flash rather than recovery.

If you are on the 4.3 bootloader or higher you use UCALJ2. Otherwise you can use UCAMA4 or UCALJ2.

See the guides in general by @perez6991 and in q&a by @dicksteele for additional information beyond that offered in the back to stock LJ2 guide stickied in general.

Okay, I'm heading over to those sections to research. I've read several guides on the forum but kept getting a little confused on which flash method to use so I don't end up bricking my device. Thank you for your reply.

One more question , if I'm simply flashing Odin I wouldn't boot in recovery to do so? I think I've confused myself.

The device has (2)....3 button combinations that are used to access either the recovery....or download mode...

Recovery is used for flashing the most common .zip format...like a CM rom...

Download mode..(Odin mode)...is used to push a complete package to the device...that generally includes a radio image, recovery, and in some cases the bootloader...and these files are generally a .tar or .img. designated file...

Using volume up, power, and home buttons at the same time will boot you into recovery...

Using volume down, power, and home buttons at the same time will put the device into download mode...

The difference between the two modes is very important when flashing files...so read carefully before selecting modes or files to flash...g

I'm a little aggravated I've been trying to flash the 4.1.1 rom but mobile Odin is not recognizing the file as a zip file. I'm not sure what the problem actually is ???

Try the Windows (PC) version of Odin. Also make sure you have unzipped and are working with the ---.tar.md5 file, not the zip file.

Follow this. http://forum.xda-developers.com/show....php?t=2618447 .
I followed sections all sections 1 threw 3. At section 2 the link for the I317UCUBMK6-TZ-PARAM.zip did not work. I used this link instead.

At section 3 don't be alarmed when it says it's downloading the update but it doesn't show percentages. It is downloading. In fact for me it automatically downloaded the 4.4.2 update instead of 4.3. It skipped it and went straight to kitkat. It took some time but I have Official KItkat 4.4.2.

Hit Thanks

You only need to flash the J2 modem from version 4.1 to unlock the phone.
