04-29-2011, 05:40 PM #1downgrade ultrasn0w 1.2.2 to 1.2.1 ??
I am running ios 4.2.1 on a 3gs with bb 6.15 jailbroken and unlocked on sn0wbreeze. The other day I upgraded my ultrasn0w via cydia from 1.2.1 to 1.2.2. Now I experience unbelievably poor batter life.
My question : is it possible to downgrade ultrasnow from 1.2.2 back down to 1.2.1? any help would be appreciated.

Thanks for the advice. In fact if anyone is experiencing the same problem, I found the instructions on how to install and where to find 1.2.1. here : Download Ultrasn0w 1.2.1 (DEB File) to Unlock iPhone 4/3GS on iOS 4.3.1 Offline [Archive] - GSM-Forum.
Just restarted iphone. Fingers crossed that this fixes my battery issue.

05-02-2011, 09:58 PM #5battery drain after upgraded to ultrasnow 1.2.2 as well
I'm glad I found this post. I too updated my version of Ultrasnow from 1.2.1 to 1.2.2, and ever since have been experiencing huge battery drain. I'm using a 3gs with firmware version 4.1. It's draining so fast that it's out of juice 3 hours after it had been completely charged.
I tried uninstalling ultrasnow 1.2.2 and then transferring the .deb file for ultrasnow 1.2.1 into /var/root/Media/Cydia/AutoInstall/. I actually had to make the "Cydia" file from scratch and added a "AutoInstall" file inside of it. Once I added the Cydia file with Autoinstall inside of it to the /var/root/Media path, I placed the ultrasnow 1.2.1 .deb file inside. I rebooted twice and though in details for Ultrasnow in cydia shows "Ultrasnow 1.2.2" with version "1.2.1", battery drain still continues
Can anyone recommend any additional steps I should take to resolve this battery drain problem?
Thank you in advance

Are you hacktivating when jailbreaking? That is known to cause battery drain.

Good to know that hacktivating causes battery drain...but, the battery life on my 3gs was minimal and was commensurate to the extent to which I was using programs known to use battery (like push notifications, location services, browser, etc) for about 4 months since jailbreaking it to fw 4.1 and unlocking it. But a few days ago, I simply confirmed some updates in Cydia, one of which was the upgrade from Ultrasnow version 1.2.1 to 1.2.2. Ever since, battery drain has been significant.
I wonder if upgrading my firmware will fix the battery drain--I've been wanting to upgrade the firmware for a while anyway, but was waiting until 4.2.1 was pretty stable/not buggy before I did it. Is the best way to upgrade firmware on my 3gs new bootrom bb 5.13.04 to simply restore to the custom firmware using pwnage tool + stock fw as usual, and then to restore to it? Or is their a new step of using "custom firmware bundle"?
