What is fastboot doing that it's not working?

Wow I'm dumb. I read the guide here(http://xdaforums.com/showthread.php?t=865685) and found that I didn't have HTC Sync installed on my laptop. Installed that and was able to fastboot flash the newest radio no problem. Thanks you guys for the guides and all the work you do.

Do you by chance know of any other way to flash this new radio without fastboot from a computer. I've tried several times to get fastboot to work on my laptop and it just won't. I've used SDK on several phones in the past but just dosen't seem to play nice with my G2.

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!

Glad you got it. There are so many steps to follow some times that it's just plain easy to forget one! It took me a while to get ADB working as well, and I think it was for a similar reason honestly.

ust like to say that I first tried flashing newest radio.img from sdcard, with no success. Then i tried on fastboot, device id came up and whatever and the radio.img sent okay everytime. But everytime it tried to write it failed saying remote: not allowed. So then i zipped the radio.img with that txt doc and renamed it and it worked without a charm. Im noticing noticable increase in signal, but not a huge difference. But thanks to everyone for there contribution.

How to flash hboot?

P.S. maybe there is a method like this? Because flashing image alone didn't work for me

Where is the fastboot folder?

I haven't noticed any difference at all in my reception. Or maybe I just didn't do any extensive testing on it. I used to abide by the saying "If it ain't broke, don't fix it..." But I guess it's hard to apply it when it comes to flashing stuffs (rom, kernel, radio, etc.). gfree_verify returned OK for CID, secu_flag, and SIMLOCK.

LOL...., I know what you mean about flashing stuff. My reception seems really good most of the time, guess Ill leave the radio alone.

Hi, I have a bell desire z unlocked, rooted. My reception seems to be bad with any radio I use, any ideas?

I just put it under C:\android-sdk-windows\tools. Worked just fine.

ddk19 · Dec 22, 2010

Has anybody noticed any improvements in signal, voice quality, etc? Does this radio jump around less? I'm in a 4g area so I'm trying to figure out how it can get any better. Thx for help ppls

Maybe it's a freak of nature but I just flashed this radio via fastboot and I got incredible reception.
Let me just say I was fairly disappointed with Tmobile because I had this phone and didn't get HSPA at home or at my work.

I am now going crazy cause I am sitting in my house now with an average of about 72 dbm of HSDPA bliss.

I have a strange thing after flashing latest radio, phone shows "G" for gprs sometimes but I'm definately having 3G / HSDPA speed, even tested with speedtest.net / bredbandskollen.se (swedish equivalent)

So i'm a bit confused on the definitive answer to this:

If I am gfree, S-OFF + SUPERCID + Unlocked then is there any danger in flashing the egypt radio? What if you accidentally flash the egypt hboot as well?

Basically, once I have S-OFF is there anything I can do software wise to really brick my phone?

verkion · Dec 23, 2010

I flashed my G2 to the newest Radio on the front page. Pretty easy procedure. For all you guys having problems, make sure you have the Engineering HBoot. Reception with it is fine. I have noticed my phone getting super hot when downloading/heavily using the HSPA connection...much hotter it seems, than before.

Don't flash the Egypt hboot ! We don't know for sure what that does yet, and it might do bad things in terms of locking down your phone.

No, I don't think there's any danger flashing just the Egypt radio on its own, if you are fully unlocked beforehand.

There are still various ways in which you could brick your phone if you do the wrong stuff, but you'll be in a much easier position to recover if you have radio S-OFF via gfree. Having the engineering hboot (the correct one for your phone, G2 or DZ) will help your recovery options too. But do that after gfree.
