Downgrade & upgrade from recovery

106 posts in this topic

I made two zips which you can install in recovery, one to downgrade to GB and another to upgrade to ICS. This way you don't need to install UPDATE.APP or do imei hack. Just install the zip in recovery and then install any custom rom following its instructions (wipes, etc).

DOWNGRADE TO GB: http://www.solidfile...m/d/e208f49ff9/

This will install GB baseband (B895), GB bootloader and CWM5 recovery. It doesn't include a rom.

UPGRADE TO ICS: http://www.solidfile...m/d/7d1f753ecb/

This will install ICS baseband (B952), ICS "unlocked" bootloader and CWM5 recovery. It doesn't include a rom.

So can we use this to jump from lower ics version (lower than b952) to latest ics version (b952)?

Of course it was tested, otherwise I wouldn't have posted it.

Yes, it installs the baseband from B952, but not the rom.

If you are using any stock based ICS rom (like Stock Plus, Lightning, Infusion, B952-slim, etc) and you are tired of reboots caused by the bootloader, you can install the zip to downgrade to GB and then install the zip to use ICS roms in GB from here:

You don't need to make wipes or reinstall the rom, just flash those two zips in recovery and reboot. I think this method is better than relocking the bootloader.

Is there another way to download the downgrade zip? Depending on the browser I either get download failed or forbidden.

This is working just fine, used it to flash B952 update.app, to leave bootloader locked, and hopefully get rid of 3G reboots.
