Guys, do you have working links for the GRI54 radio?
I looked for it at this topic http://forum.xda-developers.com/showthread.php?t=975105
But none of the links worked out.
Can someone post a working mirror?
Thanks!

Strange, I have the XXKB3, but with GRI40...

I installed this nandroid backup provided here: http://forum.xda-developers.com/showthread.php?t=884093
The Nexus S is now stock and unrooted. But my baseband version is still: I9020XXKB3
What is the original baseband version for android version 2.3.1, build number GRH78 and how can I go back to it?

not sure why you want XXJK8.. XXKB3 has the best performance for most people but whatever here it is.

Thanks
It is just that I wanted the nexus S to be completely stock. I dont know if I would receive OTA updates from google if I had baseband XXKB3? And I think the baseband XXKB3 is for the european version of Nexus S?

GRI54 is European. CM7 follows American.
So pretty much KB3 is a European radio, but they both work the same. Whatever is the best for you, use it. It's not a big deal.

This radio thing is getting confusing. I am in Asia which I think follows Europe more closely compared to US. But my Nexus is from bestbuy. I should be using the europe radio then?

I really don't think there's a difference between Europeans and Americans radio. The Nexus S works in predetermined frequencies for GSM (850/900/1800/1900) and HSPA (900/1700/2100) and that's it. So no matter where are you if your carrier support those frequencies the phone is gonna work. If it don't than you gonna have problems, probably you won't be able to use 3g per example.
Besides all this stuff is regulated and follows same patterns to ensure compatibility betweens networks so the same phone can work in several caries. That's the whole point about most phone are quad-band for GSM (more frequencies so it's more likely it will make calls) and tri-band for HSPA.

[Radio]Skyrocket Radio Thread

Here are cwm zips for the radios we have available at this time(that work). These will work for both the AT&T Skyrocket and the Rogers Skyrocket, take your pick I will be updating this thread as new radios become available. Please do not ask for the Japanese SC03DDCMKK3 radio, it does not work properly with our device.
Included in these zips:
mdm.bin
amss.bin
RIL
How To Flash:
Install with clockworkmod like you would any other zip.
I have tested these myself, as well as others on IRC and they have worked fine. I am not responsible if something goes wrong for you.
1. Original Shipped AT&T Skyrocket Radio I727ATTKJ2 and RIL
This is the radio that shipped with the AT&T Skyrocket, it is RAT interface locked which means you can't change bands by dialing *#2263#*

2. Original Shipped Rogers I727RUXKJ7 Radio and RIL
This is the radio that shipped with the Canadian Rogers version of Skyrocket, it is not RAT locked and bands can be changed easily by dialing *#2263#*

3. AT&T 2.3.6 OTA Update Radio I727ATTKK1 and RIL
This radio is also RAT locked

If anyone has flashed the AT&T 2.3.6 update, please pm me and I will walk you through extracting the radio so others can flash it

So you mean that once we flash to the 2.3.6, we can't just go back to .5?

why would you think i meant that lol...I need someone who has already flashed the 2.3.6 update to extract the radio from their device and send it to me so i can make cwm zips for everyone else to try Using this method to flash radios there is no verification check for upgrade/downgrade, so you can flash them back and forth all you want.

Thanks for doing this!!! I ended up going out after work so didn't get to it like I planned. If you don't mind I'll just link to this thread but you'll probably be stick-ied too. TA.

Your welcome, and if it needs to be stickied say the word...I can do that myself hehe.

I flashed nandroid to 2.3.6 so I have it available if needed.
Edit: Well after further investigation I read that nandroid back-up does not contain radio...so, oops

Thanks. Finally able to update my radio. Much appreciated for the effort.

For AT&T, which radio has the best reception in you're opinion...

After much testing, the current selection of radios seem to offer no difference in performance, the major difference is that the Rogers radio is RAT unrestricted vs. RAT restricted AT&T radio, which allows you to type "*#2263#" in the dialer and set the phone to 2g only, 3g only, 4g only, etc.

Ok... so I totally managed to **** something.
Picked a band, and I can't get signal anymore. Reflashed TPC v3, nothing. New modem, nothing...
Crap.

FIXED IT! Apparently taking out my SIM card and putting it back in fixed it.

I'm running KK1 and can dd a partition if that's what you need. PM me or message me on irondust(lart).

Hey, noob question but whats the point of flashing this radio lol? Does this actually allow you to use the radio that the skyrocket was supposed to come with but doesnt have an app for?

These are the firmware that control the Cellular Radio, DSP (Digital Signal Processor) and various bootloaders, not the FM radio that may or may not be part of our bluetooth chipset
BTW, AT&T 2.3.6 KK1 radio coming up shortly courtesy of lart, I'm just packaging it up now

Thanks for the fast apply, I appreciate it =) I wish we could get the radio to work on the phone if it really is built in

Did anyone take close up photos of our motherboard yet?
There are various FM radio drivers contained in the kernel, but all of them are disabled @ stock config. No idea if the chip is actually present or not, or if it is, if it's physically wired to the headphone jack (FM radio uses headphone cord as antenna generally speaking)
Close up pics of the motherboard would tell us if it's there or not

I just tried out the rogers radio (I am on ATT) and I was getting extremely low data speeds on EDGE, UMTS, and HSPA+ (10kBps) (tried both phone and PTA apns). Making calls worked fine though.

Flashed the radio and am playing around with the bands using 2263, looks like I can force EDGE by selecting GSM (I assume we should select the 850/1900 for AT&T) and can force hspa by selecting the WCDMA)
How would I force it into 3G only mode, (UMTS?)

Is possible to flash a gingerbread radio on a ICS rom?

Title says all, i noticed bad signal with latest 3.32 firmware and i remeber was very good in GB ( i got the right RIL )
Is possible to flash a Gb radio in ICS rom? thanks

Try it - should work but depends on the lib files I guess

I thought I'd try. On 3.24 base (HB 1.27.1100) and I flashed 10.58.9035.00U_10.15.9035.02_2 via the PG58IMG.zip as I couldn't be arsed to get a cable and fire up adb...
I managed to call myself and got my voicemail ;-)) So it looks like the answer is yes.
WIFI seems to work.
Mobile Data worked, only got EDGE but that might just be where I am.
I'll leave it on this version and see how the battery works out. Then probably swap back to the 3.24 base radio tomorrow.
NOTE: I didn't bother changing RIL and it worked straight off. Hmm wonder if that's related to the EDGE connection.
EDIT1: Applied the 10.58 RIL and nada, then noticed a post about some files that get flashed that might cause an issue. So I applied the 11.69 RIL and it was on H then dropped to E, switched mobile off and on and nada. Hmm rebooted and it locked in to H. I think it's my current location that's the issue with Mobile Data. Just tried Speed Test on WIFI it reported 12.5 Mbps download.
So in Summary it seems to work but can't confirm definitively.

[Q] Nexus S weak Wifi and GSM

I recently purchased a Nexus S (M200) and I am experiencing very low Wifi and GSM signals. In fact, it's so low that I can't even make calls from GSM when indoors and need to get outdoor to get fair signals. Similar issue is with Wifi and I have to be within 10 meters to get a stable Wifi connection.
I have tried various roms and kernels but the problem remains. Even went back to stock gingerbread rom and the same problem. Any suggestion to get this fixed? Seems like a hardware issue and my phone is not under warranty!
Help appreciated.

I experienced the same thing on Cyanogen 10.1 nightly but when I was on stock 4.1 it was ok.
Maybe it's your provider which don't have a good network where you are.
I am sorry for my english I hope you will undrstand me.

I can try that. Any suggestion for a reliable radio to use?

You should get the most recent baseband (radio) firmware update for your model of Nexus S. If you search the forums, you should be able to find a thread all the basebands linked. Be sure to only install the one for the model you have, because the wrong one will not work.

Flashed the latest and tested a few others but the same problem

Hi, kamran666,
If you purchased it used I would check if WiFi and GSM antennas are there and properly connected.
Take a look on this video from 2:33.
Hope in might help.

setings > about phone > baseband will give you your current version.
Compare the version there against the versions listed in the flashable modem thread, which you can get to via the links thread in my signature (section 6.1)

Thank you both. Found it and it did indeed flash. Now T-Mo falls back instead of dropping completely...
