Going from 2.3.x (Gingerbread) to CyanogenMod 7.2 (Gingerbread) is surprisingly simple unlike upgrading from Froyo. I’ll go into more detail below, but there are two necessary bits: an updated recovery rom and a custom (non-official) CyanogenMod rom. This version of CyanogenMod is specific to the Samsung Gio.
Before upgrading your Samsung Gio, you must first be running at least 2.3.x (Gingerbread) before continuing because of the use of ext4 instead of rfs. Please follow my upgrade guide “Upgrade Samsung Galaxy Gio from 2.2.x Froyo to 2.3.x Gingerbread” first.
Warning: Caveat emptor – While I used to this process to update my phone, I take no responsibility if you brick your phone. Be sure to back up anything you wish to save, this procedure works best when your Gio is fully wiped of data.
Awhile back I wrote about ‘Doing battle with a Dell R620 and Ubuntu‘ where I touched on the fact that booting from USB thumb-drive was a painful problem. In short, the same USB thumb-drive that would work in the R610 would not work in the R620.
It comes down BIOS support for USB and how it is handled. On the R610 there are 3 options: ‘auto-detect’, ‘floppy emulation’ and ‘hard drive’. Auto was hit-or-miss, floppy would not work but ‘hard drive’ worked every time. On the R620 there are no options so I can only suppose that it supports ‘floppy emulation’ upon detection of a USB thumb-drive.
Dell System E-Support Tool (DSET) is an informative tool used by Dell’s support engineers to help diagnose problems for their clients. It is almost a requirement now and Dell usually refuses to continue support without a DSET report.
The problem is that DSET is only supported on Redhat and SuSE Linux and there isn’t any information on how to get it running in Ubuntu. I’ve assembled a rough guide on how to get DSET up and running on Ubuntu 10.04 and 12.04 and it is tested against a Dell R610 and R620.
There is a new version of skype out for Linux, version 4.0 which has interesting changelog entries:
* Much lower chance Skype for Linux will crash or freeze
* chat history loading is now much faster
* …several investments we made in improving audio quality … and improving video call quality
* …extended support for more cameras
* and more
Good enough for me! There is still no true 64 bit binary/package from Skype. The result is that their fake “64 bit” Skype needs an additional 100MB of i386 packages in order for it to run properly.
