Help Un-do ICS?

[Lateck]

I forced up-graded (not OTA) to ICS (4.0.4).....
Now I am very much considering going back to EL29.
Where might I find a zip file with the Sprint EL29 Honeycomb OS?
The reason is battery usage... I only get 1/2 or less time out of a charge with ICS....
I did do a complete factory reset after I have ran ICS foe a few days and that has not helped other than being pain in the rear.....

Any suggestions on where I can find the old OS?

Thanks,

Lateck,

its take a day or so for the battery to get back to the level it was before.... just a thought.

You cannot go back the the EL29 GB ROM without rooting your phone. Once you have rooted it, then you can find a GB ROM and flash that to the phone.

Can someone give step by step to going from OTA ICS to GB or post link containing said step by step.
