The Faria ROM I have been using for awhile started having issues recently. I was having to soft reset more often (sometimes a couple of times per day), and I couldn’t turn on WiFi anymore. Memory would start at about 21MB and slowly work its way down, though a lot of that is probably due to the applications installed.
So I figured it was time to either reflash with the Faria ROM or use another. I settled on another, discussed here at XDA Developers. This is a 6.1 ROM, which is nice because of some of the improvements, such as native threaded SMS. I also have more memory after a reset: about 24MB versus 21MB with Faria. Usage feels much snappier, too. I thought that it might simply be because OMAPClock is included, but when I checked it I was still running at 180MHz. So if it feels snappy now, I can’t wait to try it at 252MHz, which is what I normally run at.
Getting WM6 on my Cingular 8125 proved to be a much more vexing challenge than I anticipated, especially considering the development for it over at xda-developers.com. The main issue was getting the 8125 CID Unlocked, which allows non-home carrier ROMs to be installed. Running a multitude of tools to unlock the device resulted in failure but I couldn’t figure out why because it was supposed to work, especially on the Wizard.
Then I found this post on xda-developers.com which indicates that Wizards that have been upgraded to Windows Mobile 5 with AKU2 (notable for the DirectPush functionality) have the portion of the DOC (Disk on Chip) that stores the carrier ID set to read-only. Faria’s instructions show how to successfully CID Unlock the device by first downgrading the ROM to a non-AKU2 version. Of course, it can’t be any ROM since the CID is still locked, so it has to be one from Cingular or something cooked.
I could not find anywhere the Cingular 1.8 ROM that is recommend to use. I trolled Google, AT&T forums, xda-developers, Google Groups, but the binaries had been pulled awhile ago. The other option was a cooked ROM that doesn’t check for a carrier ID. Again, I could not find the one mentioned, until I found a forum post that linked to another post on a French forum where the ROM is available. That took awhile to download.
After finally having all the pieces necessary, I was able to downgrade this morning, CID Unlock the device, upgrade the IPL/SPL, radio, and finally Faria’s WM6 ROM:
Combining information and steps from a several different topics at xda-developers and elsewhere, this is what I did:
- Downloaded and installed the custom 1.05 ROM, called CUSTOM__RUU_Wizard_1050412_WWE_101_11210_WWE.exe.
- Downloaded and ran lokiwiz’s CID Unlocker .2b.
- Downloaded and installed the T-Mobile 2.26 ROM.
- Downloaded and installed IPL/SPL 3.08.
- Downloaded and installed radio 2.19.
- Downloaded and installed Faria’s WM6 ROM.
