Froyo for AT&T/Rogers (build EPE54B)

bluezz · May 22, 2010

I have been checking the massive froyo thread since it was on page 7 (now its > 120 pages) but still no love for AT&T/Rogers Nexus one.
My phone is unrooted and running stock rom with Firmware on 2.1-update1 and build EPE54B. Can people who have froyo on their at&t nexus one please post a step by step guide?

Should be the same method and file as that used for the T-mobile compatible phones.

The update zip as it stands is only for ERE27-FroYo... sorry.

That makes no sense.

The guides are ERE27 only because that's the latest Eclair update. You need 2.1 update 1 to be able to jump to Froyo. You guys have the AT&T/Rogers version, which has a newer radio than those of us with the T-mobile compatible versions. If you're on the AT&T version, you already have the most recent update and can simply flash the file everyone's talking about. If it weren't compatible for some reason, the file would not flash and simply give you an error message. So there's no risk here.

I saw many at&t owners have froyo successfully flashed. They flashed to ERE27 first. Does that need rooting?

Thank you for this information.

Anyone tried this?

the update file is labeled signed-passion-FRF50-from-ERE27.1e519a24.zip

ATT/Rogers version is running build EPE54B. The update is from ERE27 to FRF50

I guess the 20 pages of 100% stock AT&T guys not being able to flash this are just morons then.

The update zip only lets you go from ERE27 to FroYo. Those with an "AT&T version" and FroYo had to flash ERE27 first... that also means unlocking the boot loader.

Yup, AT&T/Rogers folks are going to have to wait unless they want to unlock their bootloader, flash to the 27 build and then update to FroYo.

At this point there's no point to unlock the bootloader if you've waited this long already. Keep your warranty and wait a little longer, I'm sure an update for the Rogers build will surface soon.

That sucks.

Same problem with the european stock shipping ROM (EPF21B).

Can't wait to be able to get Froyo without unlocking.

unleashed12 · May 22, 2010

What a bummer! Yeah I have waited this long to preserve my phone's virgini.. I mean warranty so I guess I'll wait longer.
At least its good to know that the build for at&t and rogers is the same!

I have the AT&T N1, and earlier today I flashed and formatted my phone back to new. I now have Froyo and it's working fine.

Clearly rooted and unlocked bootloader, otherwise he wouldn't have been flashing anything.

I have successfully flashed Froyo on my (AT&T) N1 with this:
http://android.modaco.com/content/g...com/309286/frf50-froyo-pre-rooted-update-zip/

I previously was on CM 5.0.6 with Amon RA Recovery v1.7.0.

I wiped and installed the update, it did flash a new radio. Rebooted and Froyo was waiting for me!

Hope this helps anyone that is not sure.
