Can I upgrade Radio Rom?

---

Hey guys, I was wondering if I could upgrade the Radio Rom. I tried to find out what my Radio Bootloader was through the WIKI site but could not get the commands to work. All I know is that I have:

Rom Version: Schap's 4.01
Rom Date: 10/03/07
Radio Version: 1.16.00.00
Protocol Version: 32.53.7018.01W
ExtRom Version: 4.01.20071111

IPL: 1.01
SPL: 1.40.Olipro

I think that I need a newer Radio Rom as that one seems a bit old. The phone takes about 1.5 seconds to come back from sleep when clicking the power button.

You will have no problems upgrading radio. My phone started with 1.16 and is no up to 1.54.

sure, you can update the radio.

i suggest upgrading your IPL/SPL to HardSPL 7 or 9. i am currently using HardSPL 9 (2.60 Olipro), at the very least if you have a corrupted radio flash you will have your system bootable instead of a dead brick.

check out the ftp repository for xda-developers, you will be able to find v7 there (v9 is in the upload folder, but make sure you _only_ use it if you know what you are doing.)

Definitely upgrade SPL first, also do a little reading around, some radio roms work better in some countries than others and better on some network providers.
