Eris Goldcard - Giving it another try...

---

Alright, so we have certainly come into a problem here. We have a rooted 1.5 release, but we can't find any way to downgrade from 2.1 to 1.5. So how do we do it? Well I noticed no matter what device, whether it be the MyTouch Fender Edition or the CDMA Hero; they have had success using a goldcard to downgrade. Unfortunately, the eris team has had no luck in doing the same. Has anyone tried using the successor of QMat to create the goldcard?

So anyone running 2.1 on the Eris can give this a try. Follow the CDMA Hero Goldcard tutorial on this site: http://forum.xda-developers.com/showthread.php?t=572683

Except instead of using the QMAT application in step one, download the PSAS application from this site: http://psas.revskills.de/?q=node/6

After you create your goldcard: Try flashing the MR1 or MR2 update. You can find the MR2 from here http://www.pcdphones.com/phone_downl...zon%20Wireless .

If this new application does not work, I will attempt to contact the developers of QMAT, as a goldcard should work if it is working properly.

psas 1.07

Downloaded PSAS 1.07 from your link and run it through AVG anti-virus with the following results.

psas.zip";"Virus identified Win32/Themida";"Infected"

are these false or is this really infected.

I can verify that is how my gold card was made and it does not work.

Alright Binny, I'll go ahead and contact the devs and see if they have any ideas.

This is what PSAS claims on their site: "All downloads from this site are confirmed to be 100% virusfree. Some virus scanners however (like NOD) tend to report it as virus, although it isn't."

Feels a bit like I'm kicking a dead horse, however;

I've also created a gold card and was unable to get the RUU to run its course. Sad day for 2.1 ers

Gold card DOES NOT work with 2.1. I'm assuming that they messed with how they are created in the newer hboot version. Thanks apreichner for talking to the devs for us!

Hi everyone. It's my first post, but I've been following your activity with some interest. I did a little research on goldcards and QMAT/PSAS.

Turns out that as of a year ago anyway, the PSAS dev team was two people: viperbjk and cmonex, who are members of this forum. I also discovered that the latest version of PSAS only generates goldcards for older devices like the G1 unless you register the software and pay viperbjk a fee. Here's some of the drama surrounding that decision (not a full link since I'm not yet allowed): showthread.php?t=485364&page=21

Before there was QMAT, there was a Perl script called typhoonnbfdecode.pl which was developed by itsme, also a forum member. This script was written for HTC Windows Mobile devices, but I gather that the CID encryption algorithm is similar for our Android devices. I think that QMAT/PSAS is just a another implementation of the algorithm, although extended for newer devices (i.e. some extra reverse engineering that viperbjk & cmonex are now charging for). There's lots of old information in the forum about the itsme Perl script, but the links for the Perl script seem broken. However I found a copy on the web (don't know if its the latest version), and it is attached.

So anyway, it seems to me that we either need to rediscover how to make a goldcard for the newer Android devices (starting with the itsme script), or start paying off the PSAS dev team...

lurker/n00b question here

What is PSAS supposed to be doing, exactly?

From all I can tell by the instructions, I'm simply reversing the string that I got from the adb command (although, in my case, it's dropping the last character from the initial string in the reversed output).. I'm assuming it's no better at reversing strings than QMAT, so I figure I must be missing something? :)
