Downgrade Radio

I am having issues with my phone dropping calls and wanted to downgrade the radio. Is this possible on CM7? I have the latest radio as of today but it also happened on the last few radios. It's not the ROM as I have tried several ROMS and experience the same issue.

Sure thing, just download a radio from here and flash in recovery. If you're also using the CM7 partition layout, use fastboot to flash it

+1
Also as stated above if you have S-off and CM7 partition table use ANDROID FLASHER and flash the radio.img file.
You get the radio.img file by extracting the xx.xx.xx_xx.xx.23.zip file.

Thanks - I can flash easy in recovery (no cm7 table) I just wasn't sure which radios I could flash with the ROM I am using.

The Fastboot method is saver but you need s-off:
fastboot flash radio xyz.img
Fastboot check the verified the image.

You can use any radio really, but to find out what radio works best with your rom, you should ask your rom chef

I usually download from the link already posted above, http://forum.xda-developers.com/showthread.php?t=687464. Save it on the root of my sdcard.
In CM7, I then do a reboot by long-pressing the power-button and choosing reboot, then Recovery.
After I have booted into recovery I choose install zip from sdcard and choose that file I downloaded.
Done!

I heard before that if you downgrade your radio, you might lose your GPS, and it aint work again???? Is that right?? And i have another question.
I have the latest radio, and i want to go back to froyo, is it ok ?
Thanks in advance.

Just flash in recovery

Yes, but you might need to change the ril. Frankly, I was lucky that I never encountered any issues with this.

[Q] Need to flash Radio for new ROM?

I bought a DHD that already has S-OFF and currently using Android Revolution HD/4G 2.1.
I want to update to the latest Android Revolution HD (5.1.10) and just want to confirm some things...
It is recommended to flash Radio 12.54.60.25_26.09.04.11_M2 and I am currently using 26.03.02.26_M. Is it a must to update the Radio? and will I also need to update the Kernel?

No, it's not a must to update the radio. It's only recommended. You can flash whatever radio you desire. And no. A kernel is included in the rom but if you like to flash a new kernel you can do that.

Anyway, although is a risky process, doing it through fastboot is not very difficult to do. I don't know how it goes with another radio since I updated mine to install ARHD.

Thanks guys. got it all working good now.

The newest ARHD always includes new radio.

are you 100% on this? I was sure radio had normally to be flashed via fastboot not through clockwork, respect to the developers if they do go to the trouble of integrating the flash of the radio into the rom though

I can confirm that ARHD does not include a new radio, just RILs for the recommended radio.

Dev says to flash radio they feels better for their ROM.

about radios

Hi all i am currently using GV rom with radio:
32.44.00.32U_5.09.05.30_2
since i am having some wifi connection issues i was thinking of flashing the latest which is 5.17.05.23 at adams thread.
my qn is can i just flash the zip file over it and become 32.44.00.32U_5.17.05.23? i see some having 32.54 etc..
pls advice.
Thanks

If you are not s-off or flashed custom hboot, go to recovery, wipe dalvik cache + cache, flash as zip and reboot.
DO NOT TOUCH YOUR PHONE WHILE FLASHING RADIO!!! If there something goes wrong, your phone will be bricked.

If you flash latest version and works correctly, you will have 32.56.00.32U_5.17.05.23.
And use the thanks button, do not say it.

Also have a look at your router and maybe consider changing the channel?
I have read several posts advising channel 11 or above

thanks for all the replies.successfully flashed new radio.

It's only recommend to do this and as far as i know only for aosp roms. For sense roms you do not need to flash any ril after flashing radio.

[Q] How to backup radio in stock rom?

Hi,
I have rooted my wildfire and installed some roms.. now with my current animos-sense rom i couldnot get my network signal properly.
Can i backup the radio from my stock rom so that i will flash it afer installing custom rom?

If you are using a standard GSM HTC Wildfire, you can get the Radios from here, since they are common for all GSM Wildfire's across the globe.

No. Custom roms won't touch the radio and hboot.
Only stock roms (= RUU or OTA) will overwrite them.
Also you can update radio from recovery or from S-OFF hboot if needed.

No, Clockwork mod doesn't touch radios.

Doktaphex,
Thanks for replying Then we have to flash the radio back to stock radio, right? Is there any source of the stock radio (in the forum or other website)?

if u installed the radio recommended by the developer of the ROM u flashed maybe its better to keep as the developer may see its best for his ROM

Yes. You're right. I need to restore to stock radio because i want to revert my DHD to stock ROM2.2, that's why i need to find ROM2.2 stock radio.

When you run the 2.2 RUU a file called "rom.zip" will be created in your temp files. Find this, copy elsewhere and unzip. Find radio.img and flash that with fastboot.
Sidenote: when you restore using a RUU the radio will be restored too.
