[Q] Froyo update fails

---

Background:
I have an unbranded desire, which I rooted using Unrevoked 3.
For some reason, my phone says it's up to date, though I'm still running android 2.1.

Problem:
I downloaded froyo from the net (tried two versions, one which is 86,491kb and one which is 92,262kb), I tried updating using the recovery option, but I always get the following error dialogue:

"Install from sdcard...
Finding update package...
Installing update...
assert failed: file_getprop("system/build.prop"
, "ro.build.fingerprint") == "sprint/htc_supersonic/supersonic/supersonic:2.1-update1/ERE27/195459:user/release-keys" ||
file_getprop("/system/build.prop", "ro.build.fingerprint") == "sprint/htc_supersonic/supersonic/supersonic:2.2/FRF91/218634:user/release-keys"
E:Error in /sdcard/update.zip
(Status 7)
Installation aborted."

If I enable the signature verification it fails with a signature verification failed error.

I'm going crazy already trying to update, would be glad to hear any suggestions,
Thanks,

Joel

You CAN'T upgrade on a rooted phone with the OTA update

Your choice is unroot and suffer the buggy OTA Froyo rom or rejoice and install a custom rom that has many fixes for Froyo already applied

what's the best and most stable ROM and how's the best way to go about installing it?Cheers BTW i've got a rooted Desire which is unbranded and unlocked original.Just got it rooted today.

See the other thread where I answered this question but you should try Neophyte 1.6 which is the best Froyo Rom imo or Pays Rock Solid if you want a great 2.1 rom.

I had exactly this problem here is my thread

Hope it helps

why so many of you suggest Neophyte 1.6?
