[REF] The HTC Vision (Desire Z & G2) Radio ROM & Official BLs Thread

ok, thanks. I think the original post here could do with being updated with that info.
oh its a sevenzip, its still a zip file but more compressed.
They will need to be turned into a normal flashable.zip before they can be flashed.
I tried to extract the the radio from file posted here, then made a .zip version and tried to install it from clockwork recovery, but that did not work.
I really want to update the radio because I have horrible reception on this phone, most of the time the data speeds are very slow and phone calls go straight to voice mail. My previous phones haven't been this bad, in terms of reception and I believe its a radio firmware issue rather than the hardware.
If you can, please help on how to update the radio...
thanks
What radio version do you have right now ? I have a version that is more up to date than any in this thread, though I don't know how to dump it.
This current thread needs sorting out. It's out-of-date now and doesn't include any details of how to flash the radios etc. If the original poster isn't going to maintain it, then perhaps we need a new thread ?
Haven't put any guide on how to update the Radio ROM because at the moment you should really know what you're doing. And if you don't know how it's better not to do this.
Anyway, if you've got a ROM with updated Radio, please PM the link to me and I'll extract it and put it here

I've PM'd you about this.
I don't really understand the first bit of your response though. Without instructions, how are people expected to know what they're doing ? You could say the same thing about rooting/S-OFF, e.g. best not to give a guide because people should know what they're doing ?
There's a typo in the URL. Have a look at your address bar and you'll see it.
Should be www.megaupload.com/?d=LWM93BLJ
Do different radio versions result in different signal strengths ?
I have an unlocked DZ from Bell Mobility in Canada, I am using it on an 850MHz 3G network in Australia (Telstra, NextG).
When I do a side by side comparison of the signal strength between a Desire and a Desire Z, the DZ is typically 1-2 bars less (approx 4-6 asu less).
I would like to see if downgrading the radio firmware in the DZ will resolve this difference. My radio firmware baseband version is slightly different to the latest on the first post. It is:
12.28b.60.140eU_26.03.02.26_M with no "Vision_RADIO_" in the string.
The latest listed is:
Vision_RADIO_12.28b.60.140e_26.03.02.26
If you have upgraded to the latest version, did you notice a reduction in the signal strength ? Desire users noticed this when they installed Froyo and it also updated their baseband radio version.

Your probably not going to want to downgrade the radio...alot of the times people brick there phone when they do this...so ive heard...i stand to be corrected tho! I would suggest verification before proceeding to downgrade the radio

They're the same. I'm not sure what that "U" and "M" mean but I'm sure that the numbers are what matters. I don't think my DZ's signal is that fantastic either, but we're going need to wait for further updates, it seems.
modified death grip
Thanks steviewevie and 1337droid for your replies. I think I have worked out what the problem is
After doing plenty of reading and experimentation, I can now get my HTC Desire Z to display a similar signal strength to my wife's HTC Desire as long as I don't hold the DZ in some modified death grip.
Who would have thought. If I hold my DZ along its side and don't place any part of my fingers or hand against the rear (mainly lower) surface, the signal strength matches the Desire to within 1-2 asu. (the formula for asu = (Signal Strength in dBm + 113) x 2). The more I touch the rear, the more the signal strength degrades on the DZ. I don't have a rubber bumper or case for it, as this was Steve Jobs' solution for Apple's iphone 4 antenna issues.
This is not a major inconvenience to me as I have never had a call drop out yet even if I do hold the phone in a sub-optimal manner, but having it hover on zero bars during a call when inside my home or workplace is a bit unsettling. From now on I will consciously hold the phone on the edges with my pinkie along the bottom edge during a call - this is not an un-natural way for me to hold it.
The other thing which initially made comparisons more confusing for me is that the response time is slower on the DZ. This is the time it takes to increase its signal strength in response to external changes (like changed handgrip, or changes to its physical location relative to internal/external walls etc.)

In this case rubber cases and the likes wouldn't help improving your signal quality. The reason they help with the Iphone is that its antenna can actually be short-circuited by bridging that gap with your fingers. Obviously with the DZ's internal antenna, this is not possible here.
There are several different stock ROMs for the DZ, depending if you've got a standard European one, various Asian models, Bell, etc, etc.
That is the RUU with the shipping ROM for the standard European model, yes.

17Welcome to the HTC Vision (TMOUS G2 and Desire Z) Radio ROM & Official BLs Thread!
Well, my old HD2 Radio ROM Thread became a reference for all HD2 users, so.. I'm retrying this here now

Installing:
0. Make sure you've got the ENGINEERING HBOOT installed on your device!
1. Download the archive
2. Decompress it, you'll have a .img file (its name should be "radio.img")
3. Copy it into your fastboot folder
4. Boot your device into FastBoot mode and connect it to your PC via USB
5. Go into your Android SDK folder with CMD (Windows) or Linux terminal
6. Flash the Radio on your device: "fastboot flash radio radio.img"
7. Wait until the process finishes. You should read "COMPLETE" on your device's display.
8. Reboot
9. Enjoy!
Please note that you should flash a new radio only if you really know what you're doing!
NOTE: 26.04.02.17 is known to work on G2 and most probably all the radios are flashable on both G2 and D-Z.
Happy flashing!

That doesn't apply to the G2 as all SPLs and radios are compatible, so far...
The main reason is that fastboot won't let you flash a corrupt radio where as a zip will flash indiscriminately in recovery.
It's also a good detriment from flash happy noobs. They should take the time to learn and figure out what an spl is.

Well, I attached a file "android-info.txt". Pack it with radio.img in a single ZIP file.
Then rename it as "PC10IMG.zip" and copy it to the root of your SD card.
Finally, start the phone in hboot BOOTLOADER and wait a minute, it will automatically update the radio without connecting to the PC.
It works for me, hope it helps!1
That would be hardware..you can't actually change the frequency of the phone..the radio is the software side of things as far as I know...you could probably use it in asia but only get 2g data..I know
