Help to downgrade from O2 RSU4.21 to the RSU4.16

[devenson]

Please help me to downgrade my XDA from latest version RSU4.21 to older RSU4.16. I found, that the older version works better with GPRS.

And one more question - Has anyone tryed QTEQ Radio upgrade RSUv1.15_(GPRS_T32500_ENG).exe? As I unerstood, It's impossible too to downgrade from this version?

What is easiest way to downgrade to RSU4.16?

I have it as the original RSU on my device but not sure it works for Europe and it has no problem to move from/to it.

You have to get SD card to make a backup from your ROM+RSU and then you can down load your favorit RSU from www.yorch.net

Good luck :)
