Trying to go from 2.3.4 (EP1) back to 2.2.1 (ED2 or EE4)

[codythibeauuu]

Hey. So, when I first got my Charge, I flashed over a leaked build of GB. Rooted, debloated and the EP1 version. After a month or so using that, it's become very buggy and data/cache wipes and resets aren't going so well or helping me.


Therefore, I'm trying to flash over a Froyo build (ED2 or EE4), whichever works. When I try flashing one of these stock images (non-rooted, stock) using Odin, it won't work. Odin says that the ".md5 hash value is invalid" and won't even start to flash over the file. I'm assuming this has something to do with the 2.3.4 to 2.2.1 conversion? I've tried multiple USB ports, battery in and out, and followed all steps for flashing with Odin.

Does anyone have any suggestions on how to get myself back to Froyo, or have you ran into this situation? Anything will help.

Thanks in advance.

This is how I did mine....started Odin....plugged phone in and held volume down to get into download mode.....unchecked auto reboot.....hit PDA tab and selected my download file......put my battery in....then hit start...also have heard of USB cords being bad and causing issues so if you can try another one of those as well....

Make sure your battery is in, and just download the GummyCharged 1.9.1 odin package and youll get right back to froyo.

I could be wrong here, but I thought with going to the GB leaks you had to use the PIT file to repartition before going back to FROYO.

Also, not sure that GUMMYcharged has the EE4 Radio in it, so going to ED2, doing the OTA to EE4 then rooting and roming is the way I would go...

Okay, cool. I'm going to look into the PIT file idea. I know that the reason it's not flashing doesn't have to do with the method. I feel like it's more of a software thing that's holding me back. We'll see though.

No, need to do ED2 and OTA. You can go straight to factory EE4 using the leak on XDA. He includes a link to the PIT file.
