What is a radio update and what is it good for? I understand fiddling with it comes with risk of bricking the phone.
There are already a couple of threads about this...
...and if you have no probs with your connections and dont wanna read some threads, you better leave your radio untouched.
SO i have a question or 2 about the radio:
1. Whats the difference between flashing the .img with fastboot and using recovery to flash the zip file? Are the 32.24.00.22U_4.03.00.21_2, 32.24.00.22U_4.03.00.21_2 and 4.02.02.14 files, similar to say, the 3 img files floating around the net?
2. Is flashing the radio with or without the RIL files going to make a difference?
What im trying to do is get to the bottom of my Desire ROM issues. I was coming from CMs latest stock rom and I had flashed the 2nd radio .img that Google released (the one before the leak and the one after the stock radio) and I was getting great reception and good speeds. Whne I flashed over to the Desire Roms, my netowrk bars would fluctuate between 0 bars and 4-5 bars every 5 seconds or so. When i flash the other two img files, the problem goes away but my connection is really unstable.

I'm a bit confused here.
Google's OTA updates flash the radio too, right? If so, what's the difference between a user manually flashing it and a google-initiated flash? Why is it that we hear horror stories about people bricking their phones via manual radio flash and not when google initiates the flash? Does google's flash routine check battery levels prior to the flash and disable all user input during the flash? How is it so fail-proof?
I'd figure that if both procedures were more or less the same, wouldn't there be some reports of end users bricking their phones by allowing OTA updates on low-batteried, unplugged-from-the-charger N1's?
Flashing manually gives you the option to change when you want. There are several radio images out for the nexus. Some of the radio images have worked better for others then for some. I like the newest one the best. If you are not patient when flashing and pull the battery yes it will brick the phone. It takes several minutes for the radio image to flash the initial install and then there is a second boot up.
Probably the OTA installation checks if you've got enough battery to complete the whole process before flashing anything. Plus, I imagine it strictly advises you not to remove the battery until the operation is complete.
what does changing the radio do? lol

Radio image's should be used with the system image they were released/leaked with, so to answer question 2, yes it will make a difference. Some differences will be noticeable and some wont, and some times the radio image will not have changed at all between updates. As a general rule though, update the radio with the release it was intended for.
As for question 1, fastboot flashing is the safest way to flash ( IMHO ), though i do not know the differences.

Ok I'm new to rooting and flashing so I have a few questions that I'm pretty sure are basic but I just don't want to brick my phone. 1.when flashing a radio Rom do you wipe before flashing? 2.when you flash a custom Rom do you flash the radio before or after the custom Rom and do you have to flash the radio every you flash a custom Rom? 3.how do you make a backup of your stock radio before flashing the new one?
4. Are there specific radio roms for different custom roms or can you use the same radio for all custom roms? Thanx a lot.

Can't back up your radio. Flash a radio, and it may give you better signal, it may give you worse signal. it may boost your battery to 100 years, it my kill it in 5 minutes.
It's all about your towers, how far away you are, what kind of signal it's getting. You might get a radio that gives you full signal at home, but none at work.
make sure you have the right radio for your phone!!!!!!!!
The radio and Rom are seperate.. can be done anytime from each other.
recommendation: dont mess with the radio yet... make sure you are having issues with the current radio before you try to update it. I still have not got the never up to touch the Radio. I flash ROMs all the time. Read on Radios.. there has been a lot of issues. Some are big issues!!!!
Hello,
For the past few days i have been trying to find an answer to my question but so i've come up short. With regards to loading a custom rom, what is the process of ensuring that the correct radio image gets loaded as well? I have went as far as modifying my stock rom with dsixda's kitchen (great by the way, very easy to use), but I have not figured out what to do with the radio.img. I incorrectly assumed that it would be retained in the build, and now I'm a bit worried to try it until i know for sure where it needs to go.
Thanks for all your help,
Flashing a new ROM doesn't affect the radio at all. You could change your ROM 6 times per day and still have the same radio.
I'd say your best bet is to search around the forum and find one of the flashable .zips for whatever radio you want. They are out there cuz I remember doing that a while back. As long as you flash one meant for CDMA (DO NOT FLASH A GSM RADIO!!!) you should be fine.
Here's the one that a lot of us are using right now, the newest Radio that came in Sprint's 2.1 Stock release: http://forum.xda-developers.com/showthread.php?t=681703
Ok well that makes sense. I would use that radio, but I don't have a sprint device, so unless I am completely lost I should just stick with what I as my radio image. I have just gotten a bit confused with all the talk about using sprint rom's in non-sprint phones and losing the ability to make/receive calls,data, ect.
Just so I am clear, as long as I am clear, since I modified my stock rom to add root, wifi tethering, blah blah; the radio will be fine. So essentially, loading my rom would have no more effect on the carrier files than a master reset would. Am I over simplifying it?
Thanks, you are the first person is 5 different forums that explained this to me.
Ok yes, you shouldn't flash a Sprint radio if you're not on the Sprint carrier. Your provider may not recognize it and your phone might not even get signal.
And yes you're also correct that adding root, wi-fi tether, and other such apps/mods will not have any effect on your radio at all. The radio is basically just what the phone uses to receive its signal from the tower. It's like you said...if you're not having any signal/data problems, you really don't need to worry about updating your radio.
Finally, you're also correct in that you shouldn't flash a Sprint-based ROM to your phone if you're not on Sprint. The frameworks and operating files are built somewhat differently in other providers ROMs, so a Sprint-based ROM on your non-Sprint phone likely wouldn't even work.
There are other ROMs for a few other carriers out there in the Development forum. Browse around there to see if one of those will work for you.
Sounds like you understand it all just fine
Thanks, I went ahead and took the plunge and loaded my own rom and it worked flawlessly, well with the exception of my custom boot screen image and the boot sound. I guess I need to just take baby steps I guess. Does anybody know where I can get some get directions on creating custom bootup features? I read somewhere all I needed to do was open the media folder and edit the images as I see fit. It seemed easy enough, but on startup, the screens froze and I got no sound. It did load all the way but I would like to correct this if possible.
Thanks again
A somewhat basic boot animation tutorial (that doesn't seem really good in my opinion, but a good start at least): http://forum.xda-developers.com/showthread.php?t=639471
Some boot animation instructions: http://forum.xda-developers.com/showpost.php?p=6651435&postcount=2
Boot animation preview tool: http://forum.xda-developers.com/showthread.php?t=676385
There's lots more stuff out there if you search the forum for "boot animation". Looks like some ppl just modify existing boot images to their liking rather than completely building from scratch.
Thanks, I will give them a try. I am still a little afraid to try some of the tried and true custom roms out there for fear of incompatability with my radio, so I am gonna work with what I got and continue to work on my own. Thanks again for all your help
chromiumleaf is totaly right, if your not real familiar with flashing radio's stick with the one your carrier provided a wrong radio flash can brick your phone quick.
for the boot animations when cooking them into your roms, copying and pasting your new bootanimation into the /system/media folder in your working directory, and leaving the option in the kitchen unchecked will give your better results, also here's some more info that might be helpful in building them.

Just make sure u delete the bootanimation.zip file in the media folder before u add ur boot animation cause the zip will always over rule ur animation.
Given that most of the custom roms are using RIL from AT&T Stock, I wanted to see if I can flash Bell Stock raider RIL ,
I am assuming that would prevent all the 4G/3G toggle that I still see.
RILs will not prevent the toggling. RILs are simply libraries(drivers) that interface with the radio. some people usually report that matching RILs with the radio that you are on will yield better signal/battery life. technically they should be the same between the AT&T and Bell/Rogers....
it can definitely be flashed without S-Off since they are simply files located in /system/lib, and do not touch the radio anything.
i will package the BELL and ROGERS RILs up and add them to my thread. it might take me a little while unless someone else has them ready to package up.
That would be really great..you are really great ...I may have to send some more monsters to you (Hopefully this weekend )
So would I just copy *ril.so" files from stock Bell ROM under /system/lib/*.
Assuming I backup , I hope I can do no damage , ofcourse If can edit the system.img (Doubt that it would straight forward)
Tried to flash RIL and failed (attached files I used)
So I tried and it did not work, and even reverting to backup files that I over wrote did not work
I attached the files that I tried to extract from Bell Stock RUU and I hope they are correct ones.
Hey there!
I have a strang problem with my Note, that being that I loose any signal utterly and completely after using the mobile data to some extend. Context: I live in finland right now and here they have unlimited mobile data, so I'm streaming netflix and stuff like that via my mobile connection.
After using roughly 600MB, my radio seems to completely shutdown. This can only be fixed by rebooting the device, I tried many different apps that have to do something with the device's radio, but to no use.
I'm using the latest radio modem software from this thread http://forum.xda-developers.com/showthread.php?t=1645202 (for jelly bean) and I also tried downgrading my radio (tried 4 older versions), but that only seemed to make the connection slower, but ultimately not fixing my problem.
I'm using the latest stable cyanogen mod (cm-10.1.3-n7000.zip from https://download.cyanogenmod.org/?device=n7000).
A friend of mine also has the same mobile data thingy, and he streamed and downloaded roughly 100GB in the last 6 weeks without any outages, so it's definitely my device, not the mobile carrier.
Has anyone any ideas on how to fix this?
If I forgot any important details or did something wrong, please let me know, this is my first time posting here!

Well, try a more recent copy of cyanogenmod. 10.1.3 is over a year old.
You might also want to try a different baseband

Okay thanks, I will try using the latest nightly build. What's a baseband in this case? Google can't help, so I must be googling wrong. I tried many different radio versions, but that's not what you mean I guess?
edit: Ah, yeah we mean the same things. I already said I tried using older radios, but no use. Every link i find for the newer XXLT5 is down, so I can't try that one.
LT4 is recent enough. Its what i use. If you really need LT5 or bolt, make a backup of your rom, flash a stock rom that includes it with odin and restore the backup.

I just now found an LT4 zip file, so I'll try that. Now that I upgraded to the newest nightly build (there's a new version everyday ) I only loose the connection for some seconds. Maybe LT4 will fix that.
edit: Okay false alarm, I only find complete ROMs with LT4 integrated. Isn't there a standalone .zip file? I can't flash new ROMs every 12 hours, I already lost all my photos because the SD card was formatted by accident
edit2: okay, when I loose connection, it is automatically reestablished in the next 10 seconds, so for streaming or downloading (most) stuff, that works okay. Still, is there a way to get rid of this? My friend is downloading with 3 MB/s all the time via mobile data, and I'm sitting here stuck with 500 kbit/s and connection losses every ~45 minutes
