[Q] RIL Firmware Drivers

Hi everyone,
I'm new at xda developers, and I recently started experimenting with rooting, custom ROMs, etc. I have a question about the RIL firmware drivers. Hope you guys can help me out.
Lately I've been following the progression of baadnewz's InsertCoin ROM (http://forum.xda-developers.com/showthread.php?t=1016940), a Desire port of the Desire S ROM (with sense 2.1); you probably already know it. I want to give it a try, but - coming from CM7/prerooted stock roms - I noticed that baadnewz recommends upgrading the radio to the latest version, as well as the ril-firmware-drivers.
I understand the RIL is some kind of mediator between the ROM and the radio. Therefore, is it true that a specific RIL can only be used with a corresponding ROM (version), or has the ROM nothing to do with it? The reason I'm asking this question is because I want to make sure the newer radio+ril will still work in case I decide to return to my old stock ROM. And in general, is it ok to presume that a newer radio+ril will be at least as good as an older radio, regardless of the ROM installed? (I've never upgraded my radio btw)
Thank you!

RIL is not neccesary, use it if things dont work well, it may improve situation, but it is likely that you will have to experiment till you found one that works best for your phone & rom & radio.
RIL is stored in ROM part, so every time you change ROMs, RIL you flashed is gone.
also you do not need to upgrade your radio, do it only if stuff doesnt work fine after flashing a custom ROM.
you also mentiond coming back to stock rom - when you ran a RUU, it also flashes a RADIO and a RIL, so no worries there
every radio comes with its own RIL, but experience showed, that not necessairly they work well together when it comes do diffrent devices on diffrent networks and diffrent roms.
so - flash your rom, if it is ok that leave things be, if not - upgrade your radio, and then you can start flashing RILs
remmember to make NANDROID before flashing RIL and also that in order to flash RIL you must mount \system in recovery.
radio flashes are safest from fastboot if you are S-OFF, if not you can do them from recovery

Thank you for your reply, really appreciate it
I have one last question, just out of curiosity.. You mentioned that radio flashes are safest from fastboot. Why is that?
I'm still S-ON so I won't be able to use fastboot for flashing... Would you recommend S-OFFing to minimize the risk of bricking my phone, in case I decide to flash a new radio?
Thnx

well you can flash radio from recovery, lots of ppl do that without any problems. i never tried it myself.
i think fastboot method is safer since it doesnt involve rebooting your phone during the procedure but not sure how exactly is this safer, it just has been stated many times, that flashing radio fastboot method is SAFEST.
anyway going S-OFF (cd method i used) is super easy, just be sure not to have a2sd+ or data2xxx rom while doing that.
oh and apart from minor advantages like changing your splashscreen or the ability to delete apps from \system while booted up in android there is one BIG advantage - the option to use custom partion table. I am running InsertCoin v19 on CM7 hboot version, and is not only super fast but also it provides lots of space for apps
it definietly faster than insertcoin HD data2ext i used before going S-OFF

[Q] Radio Question

Hi,
Just got my HTC Desire HD, downgraded from 1.72 and rooted with the CM7 ROM installed.
I still have the stock radio which came with the phone which is - 12.28b.60.140eP_26.03.02.15_M3.
My question is - I've checked the latest radio thread out but I'm a bit confused as to which one I need to ensure that my device remains unlocked?
Can someone point to me in the right direction please? Also, what is the problem in not upgrading the radio - are there any major issues that can occur?
Thanks for everyone's help.
Dan.

if you have installed cyanogenmod 7 yo should flash the recommended radio for this rom...
but its relative,,,,, also the good performance depends of various factors... bettwen that is your location..there are recommended radios depending of your location...
the best advice... you can try some radios (cm7 recommended.... recommended for your location...) and compare if the signal strenght of the phone, wifi, 3g etc its worse or better...
but when you go to download a radio IMPORTANT:::: check md5 checksum
flash it with the most harmless method that you know, like fastboot commander...

be careful mate..... a badly use of radios or flashing it wrong can brick the phone

So it doesn't matter what radio you get to maintain an unlocked phone?

[Q] CM 7.1.0: Radio and RIL

Hi xda`s,
Im a bit confused. Which RIL is included in CM 7.1.0 (http://forum.xda-developers.com/showthread.php?t=1297545) and whats the corresponding Radio? Im using the latest LordmodUE CFS Kernel btw.
Ive read so many different opinions on radios to flash. So id like to have everything matching. Im coming from ARHD 6.1.3. The latest radio should be flashed on my phone.
Thx in advance.

I think it's 2.2.1003G, but I'm not running pure cm7 at the minute so can't guarantee (it is the default in the ROM I'm using, and it works fine with the latest radio).
Edit: I've just noticed in another post I'd replied to from someone who was using a RC of cm7.1 that he had 2.2.0018G after flashing, so it's going to be one of those two (depending on whether it was updated for the final release).
Edit2: If you're already running cm7 just check yourself what you've got:

Ah great, thx.
Just found out that its 2.2.0018g. My current radio is 26.10.04.03_M.
Cant find a suggestion if that fits. Is someone into it?
Edit: I just found that I have to flash radio 12.62.60.27_26.13.04.19_M. Can this be done with cwm too? I read that theres a way. But is it safe or is there an easier way? I use an Mac btw and DONT have eng s-off.

Why do you "have to" flash that radio?
If you've got Radio S-OFF, you can download the radio you need from this thread, copy the file to the root of your SD Card (making sure it's named PD98IMG.zip and nothing else), check the md5 of the file after you've copied it to your card (to make sure it's not corrupted or anything), then reboot to the bootloader; it should scan your card, find the file and ask if you want to update. Click yes and you're away.
Other than that your only options are to flash using adb or fastboot, and you'd need ENG S-OFF for those to work.

It worked well thx man. No expensive brick^^

I have a similar question regarding RILs and AOSP roms.
I'm new to AOSP, but in sense there is generally one RIL per radio, and choosing it is easy ( Just flash the RIL after the ROM )
I've been searching around for a similar system for AOSP roms, but it seems as though it's not quite as cut and dry for AOSP. I know that the RILs are different and generally have G in the filename.
Is there an easy way to check which RIL i should use for my Radio on my current rom (blackice)
My radio is 12.56.60.25U_26.10.04.03_M and I'm not sure which G RIL to use. Any help anyone can offer is appreciated.

Use whichever one gives you the best performance. There's not one that you "should" use (they're all as good as each other IMO), but if you're having signal/connection/drain issues with the one you're using try another one. If not, I wouldn't bother.
If you must try, you easily can switch between the four available RILs in ICETool.

Thank you for the quick reply and the info. I thought that it might work that way for aosp but this information is great to confirm it.

[Q] Advice for 1st time radio flash

Hi all,
I'm fairly new to the world of rooting/custom ROMS - I rooted my Desire HD a couple of weeks ago and have installed a couple of ROMS since then (start on ice cold sandwich and curerntly on JellyTime). So far it's going well, but my wiFi signal does not seem to be very good. I know that installing a different radio may help with this, but I wanted to get a bit of help before doing this.
I've read the post http://forum.xda-developers.com/showthread.php?t=896597 which contains the guide for flashing a radio.
What I want to know is what radio should I be using? Is it ROM/phone/carrier specific? I don't want to flash the wrong radio then not be able to go back, especially since I've made it this far without bricking my phone! Also, could flashing a new radio improve my wiFi signal?
Thanks,
Simon

I recently flashed radio as well.
I did it with this one :

My problem was that when calling the other side heard them self twice. And its gone
and yes, It got a lot to do with wifi, 3G, calling. and most of your connectivity .

Radios are not EDIT: ROM, or carrier specific, but their performance is affected by region. They do affect wifi. If you are in the US, there is a newer radio in the radio thread out that I have used. Though it didn't improve anything for me, it didn't break anything either. You can also take note of your current radio in Settings - About phone, and download that radio from the radio thread.

In addition to what Bananagranola said, if you flash ENG S-OFF and your device was shipped with Gingerbread you will mess your bootloader and radio won't be the main concern then.
You can flash a radio in the PD98IMG.zip way (wich is the safest way to do it) or flash modified ENG S-OFF included in the Hack Kit and after that you can find the radio threads links in the guide in my signature.
Make sure that you read carefully those threads. Flashing a wrong radio might brick your device.

Radios are phone specific but I get what you meant. Desire and inspire can flash each others radios. Don't want to flash any non ace radios though as it can truly brick your phone.

Yeah, sorry, that was misleadingly phrased. I edited my earlier post.

Thanks for all the replies. I'm starting to understand! I'm in the UK, so I guess I would need to get a UK radio. How often are they updated? When I've looked around, there only seem to be a few available.
My current radio is 26.10.04.03_M Can I improve on that?
Also, I read on the LeeDroid thread that you need to make sure the radio is compatible with the ROM, but bananagranola said it's not ROM specific...who's right??! Is it a case of, when I find a radio I want to use, I post it in the ROM thread to ask if they are compatible?
Thanks.

Just try different ones out. All inspire/desire radios can be used its just a matter of how well they will work. Leedroid was just pointing that fact out. It's not that it won't work or that it will mess up your device in trying. I use 26.17.14.11 and it works for every Rom I use. You are currently using an inspire radio so you might give the one I use a try. It's also an inspire radio. But if it doesn't then you can always try another. It's good to give it about 24 hours to settle unless it just outright makes something worse like battery or signal.

Thanks for all the advice. Sorry about the delay in getting back to you - had a little issue with a bricked tablet (all fixed now though
I guess the next steps for me are to take a nandroid backup and try some out!
If I'm back on here with more questions it means something went wrong... :cyclops:

Does it matter which Radio version I have in my DHD?

I have a DHD. I just checked the baseband version and it shows 12.56.60.25P_26.10.04.03_M. It has root, s-off and a custom rom (i change roms regularly trying them all to find the right one for me).
I have another stock DHD that I currently use as my daily phone and the baseband version in it is 12.65.60.29U_26.14.04.28_M.
Physically both phones are identical just one rooted with s-off and a custom rom and the other straight stock.
I assume the baseband version is the same as the Radio version.
Does it matter what baseband version I have? Will an old baseband version mean some functions in a rom won't work?
When flashing a new rom does that flash the radio as well or does that have to be done separately?
I've read the instructions in the Dev RADIO thread about how to flash but just need to know if it's necessary.
cheers
EDIT: Just one other thing:
Is the radio version more relevant to the kernel or the rom? I often flash a new rom but try different kernels with it.

Radio are region based not rom based. Flashing a rom will not change the radio. Its something you do separately. Changing the radio wont give you that wow factor so if it ain't broken don't fix it. The .03 radio is the old att radio their latest is the .11 some dev's may suggest a radio for their rom but again radios are based on your location. So like If your in the US and dev is in Asia you would not use a radio from Asia.
Changing roms is a pretty simple thing no real risk in bricking phone but changing radios is a whole new ball game in itself with possible damaging phone for good. If you deside to change radio I would suggest to make sure its in pd98img zip form and flash thru hboot not recovery.

wow that is interesting. My DHD was locked to the vodafone network in Australia and to get root and s-off I ran the hack kit which I assume put the current radio on it because I am definitely in Australia and nothing to do with ATT.
I know the hack kit downgraded me first so maybe that's how I got an ATT radio.
BTW I thought the safest way to flash a radio was to download the radio.img file and flash it through USB from my PC connected to my DHD?

Yes you can adb it but I myself find it safer the other way.

Just to add, i have noticed myself with the newer radio i use a.t.m. i have a little better reception (very little).
But is consumes less battery and wifi wont crap out.
But like Reinaldo said "If it ain't broke don't try to fix it"...

thanks for the advice guys.
cheers

I notice that the android-info.txt inside the latest radio Radio 12.69.60.29_26.17.14.11_M only applies to cid number CWS__001. My DHD is a vodafone australia.
Do I assume correctly that if I was to attempt to flash this radio on my DHD that either
A. It would not flash and I would get an error of Incompatible device or something similar
B. I would brick my DHD
C. It would flash and be fine.
Which is the most likely?
If this radio doesn't work on my DHD what is the latest radio for a vodafone australia DHD?
cheers
