Rom and radio - EVO 4G Q&A, Help & Troubleshooting

Ok I know what a ROM is Im pretty sure but what is the radio?
I am completely lost when it comes to radio and couldnt find anything on it.
Thanks
BTW just got rooted!

Lol,
A radio is basically an image that is flashed just like you would flash a Rom. The difference is that you don't wipe before you flash a radio or wimax. Search the dev section for [RADIO] to locate the different radio images. You should make sure to check the instructions for which Rom you are using to ensure you flash the appropriate radio.
Basically the radio and wimax updates are images that update the code for, well, radio and wimax lol

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

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.

No service after flashing radio

Hello there!
I have flashed this radio: 6th September 2011: Radio_12.62.60.27_26.13.04.19_M - HTC 3.06.405.1 WWE to my Desire HD, then the proper RIL.
I used the following sources and guides and followed them step by step:
How to Flash a Radio.IMG Win/Mac by leith54
The HTC Desire HD Radio Thread by Drakknar
Radio Interface Libraries by jkoljo
And now my phone is unable to find a cellular network.
I have Cyanogenmod 7.2, Radio S-OFF, ENG S-OFF, SuperCID, ClockWorkMod Recovery.
I would appreciate any kind of help or ideas how to make it working. :angel:
Thank you!
Regards,

Okay I managed to flash an older radio now. The 12.54.60.25_26.09.04.11_M2. And it's working again. So I'm good to go I guess. Heartattack is gone.
But I'm just wondering why is it that this version works properly and the other one doesn't?

Make sure that u flash a radio that is for your phone and not the Inspire 4G....besides being similar hardware are not the same (different frequencies), so always double check that the radio is compatible with your device and that the download is not corrupted by checking md5sum....:good:

I got the radio from the Desire HD radios forum not the Inspire 4G, and checked the MD5SUM also. I have flashed Radio_12.54.60.25_26.09.04.11_M2.
Sometimes I have signal now, but it keeps loosing it.
Perhaps the problem was by flashing a different ril?
Since all non sense roms use one standard ril and shouldnot ve messed with unless its a sense rom.

Wait, what are you talking about now?
From what i get, you had 7.2 flashed a radio and ril, problem started, flashed another radio, its a bit better.
If that is what you have done till now, then just full wipe and flash the rom again to see what happens.
I have no idea what you mean by downgrade.
Radios are subjective by location. You ought to keep each radio for a couple of days to see how it works for you. They also affect battery usage and such.
Hence, just reflash the rom after a wipe and check it out.

The rom won´t solve the issue. Whenever you flash a radio you need to flash the matching ril. I have sent you and email. You will find all the information there, but ROMs don't flash radios but RILs....so if you change the radio just flash the correct ril for it.
Then you need to give the device time to settle...at least 2 or 3 days...

Unless Im mistaken, non sense roms all use the same ril. He is running cm7.2. He then flashed a radio and the corresponding ril, which in my assumption would be its for a sense rom.
Afterwards he flashed a different radio keeping all the same.
If he flashes the rom again,he will have the ril which is compatible with the rom. Thus possibly correcting the issue.
Correct me if I wrong.

Yeah that's correct I missed the CM7 thing...there's no need to flash RIL...and I guess that the radio is useless in non sense roms...probably he should go back to his original radio and then start all over again

Which radio were you running and which one are you running now? It all depends on how you root your device. If you unlock the bootloader, then nothing happens, but if you run the hack kit, you will have the lastest 2.3.3 radio, but as you would be S-OFF you can flash the radio you want back again.

Radios are never a must. You can use ARHD with the radio you have at the momento and the rom will run ok. Radios are suggested by the developers as they test or assess several radios in the process of developing the rom. However, you can still use the radio you have and probably will never experience any bug.
If you want to flash a new radio, you can always go back to the previous one as long as that file is to download. Check the radio threads to see how to flash a radio and always make sure that you check that the md5sum match.
If you need further help use the guide in my signature...
Nothing will happen to radio if you flash a stock ROM in recovery. The radio only changes if you manually flash one, or if you run an RUU. Radios are region specific and if your country uses less common frequency bands, then the one for your region will be the best. Latest is not best for radios.
