Please help with modems, nothings working - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Just switched over from a Samsung Captivate.
Flashed back to stock, radio is working and get 4g. Flash JB (SLIM JB), everything is fine. My gf could not hear me well while on the phone, it was echoey so i tried to flash several of the different radios for the I727 and nothing works. Error when connecting to network, no radio, no IMEI, basband unknown, etc.
What am I doing wrong?
Tried the Telus and stock ATT modems, the Blaze 4G modem and a few others. Absolutely no signal. Please help, I would appreciate it. Nothing in my search on the forum here.
BTW I am on telus and the telus radio seems to be fine for most but I get nothing.
I keep reading about RIL, people mention deleting the RIL with the GB modems (the telus modem is GB I believe). How do I do that?

That situation usually does not happen to me. But when it does what I do is: Take out the SIM and microSD, flash a darkside wipe on recovery (search on the forum) , flash a working modem for my device ( not a blaze or telus one), then only then flash the rom. Boot it, wait it settle for 10 min, turn off, put the SIM card back a restart.
It should work.
If it doesn't try to flash the original rom via ODIN ( can look how on vin's thread http://forum.xda-developers.com/showthread.php?t=1652398)

Only thing I've ever had to do is to reset the APN.

Thanks guys.
If I flash the original ATT or Rogers modems that came with ICS without RILs it works. Baseband shows... Most of the other modems I have flashed (with RIL) either do not work at all (no IMEI or network connection at all in most cases) or a few work but baseband is unknown.

Glad it worked out for you. Just to clarify, but as far as I know baseband Unknown means nothing regards radio functionality.

[Q] Nexus S - Canadian

I just got a new Nexus S purchased from a Rogers store here in Canada.
I am eager to start flashing some new ROM's and such but I have learned some things in the past with my SGS and I really want to make sure I have my stock radio available in case I need to flash it back.
i9020AUCKB2 is my stock modem. I have some newer modems ready to flash but I am worried that it will cripple my 3G connection to Canadian carriers.
I have looked and can't find this modem anywhere. Also I don't know how to back it up myself. I have already done a CWM backup but I have read that this doesn't backup the radio firmware.
Does anyone know how I can easily backup my own radio or where I can download it from?
+1 I've been searching for the last few days info about the exact same thing. I just sold my i9000m and was hoping to flash some new roms with this phone too but not gonna try until I either have a stock odin version of this rom or at the very least the CKB2 modem.
+1 same boat, want to know this too
Just bought Nexus S yesterday Telus baseband I9020AUCKB2.
Rooted and installed CWM 3.0.2.4 and flashed CM7 (Great ROM) baseband remained the same
from what I've been reading in Nexus S dev, Odin is something we should try to avoid if possible. I came from Fascinate T959D and I thought about it but that's probably one of the easiest ways to brick if you don't know EXACTLY what you're flashing and WHAT you're flashing it on.
Odin = last resort
lucidcoin20 glad to hear that flashing CM7 didn't change the baseband, I didn't have the courage to try it. I wouldn't flash just anything with odin but if you can find the right files it will get you out of a mess pretty quick. I agree its not for noobies with no clue what's going on but if Samfirmware comes out with the 9020a rom I'll make sure to have it on my pc for an emergency.
But from my phone wich is a Koodo version (went with them cause they were so cheap outright so I could go just cancel and go back to bell) we all have the At&t version so all Canada is the same. Hope it all works that way so I can go on CM7.
But would still like to learn how to backup the radio file in case I ever need it in the future.
Well I went ahead and flashed KB3. My speeds are less than impressive but I still have 3g with Rogers. Still looking for KB2 though to do some more testing.
Have you tryied KB1 radio, works good for me, i believe it is a US radio.

Flashed KB1 and KB3 and tested using speedtest.com app, three separate times over wifi and cellular network - the KB1 was roughly 10-15% slower than the KB3 for me..
KB3 labelled my radio as "ATT" btw

LMAO did the same thing but for rogers saved $75.
If you look in Q & A forum, there is a post for a clockwork flash, K2B radio, just posted in that forum today. I have flashed the radio, work great fore me.
You can get the KB2 radio file on my thread in the General forum at http://forum.xda-developers.com/showthread.php?p=13077026
Thanks a lot, I was unaware that the Canadian carriers used KB2. Currently I am using KB3 and I noticed that sometimes the call breaks up, however I am not sure if its the firmware to blame. Does anyone have similar experiences with KB3?
I have tested KB2 and KB3 and my tests are not constant. Sometimes I get only 1MB or less down and up, sometimes I get 5MB down and 3up.
I'm not sure why the tests are so different. I can do the tests one after another in the same place and get completely different results.
I am with Rogers and I am using the Speedtest app. I noticed at one point the speedtest app was connecting to a server in Quebec which made no sense since I am near Toronto. The test results I mentioned above do not take the Quebec tests into consideration.

[Q] Help. Flashed my Telus Nexus S with ATT firmware, now network type shows GPRS.

I'm (obviously) a bit of a newb when it comes to android, and I was flashing back from cm7 to see how it was done. When I reinstalled GRJ22, everything was working fine. I then downloaded and flashed the OTA update to GRK39C (or so I thought). It turns out it was the update to GRK39F, which apparently is ATT or GPRS specific. My phone now thinks it's on ATT and is trying to use GPRS.
I'm on Telus in canada, and use HSPDA.
The phone was also showing baseband version I9020AXXKF1, it should be I9020AUCKD1.
I've tried restoring from a backup, flashing back to cm7 and to stock fw's, and even tried flashing the radio.
My phone still shows GPRS, and now baseband version shows I9020AXXKD1.
Is there any way to fix this? I hope someone here is knowledgeable about this...
That baseband is associated with the i9020t, or the t-mobile variant. The canadian nexus s is identical to the at&t version.
There is a sticky with all the roms. Use it and get the right rom installed
Unfortunately, the ROM I need seems to be one of the missing ones. Is there any way to backup the radio from my wife's (identical) phone and flash it to mine?
It looks like the file I need is 5282b5b3eb74.signed-sojua-ota-178324.5282b5b3.zip but I'm unable to locate a working link for the file. Can anyone tell me if this is correct and/or provide a live link?
Actually that particular one you want has broken tethering... This is a dump is the 2.3.4 with I9020AUCKD1 radio from my US import i9020a tested and working on SaskTel HSDPA+.
http://dl.dropbox.com/u/7812800/Stock-GRJ22-i9020A-unsigned.zip (will need to be flashed via CWM Recovery)
Thanks! I got it working by flashing the unsigned ROM in the sticky thread, and I'm running cyanogenmod 7.1 RC now. I'll keep the stock ROM on file just in case though...

Cool... I hope it works out well for you.
btw i got a rooted version of the stock 2.3.4 if you are interested as well.
So, for some reason flashing with your ROM set my phone to UMTS. Can someone refer me to a howto to backup a full ROM image from a phone, since my wife's is working fine and is on the right type of network.

[Q] KF1 radio with telus ?

Well, here goes.
I've been reading alot for quite a while, and learning everything I could around this place. Thanks to tall who contribute.
I'm running NScollab, 1.0.42, with matrix 8.0 kernel.
Currently on the XXKB3 baseband.
Following this thread http://forum.xda-developers.com/showthread.php?t=1116884
I tried flashing the new KF1 radio for the nexus S. No luck. Either is doesn't flash at all ( status 6 error ) or when it does ( the signed version can be flashed in CWM ) no signal whatsoever. I've tried everything, changing the band, ( *#*#4636#*#* ) rebooting 45 times, dalvik wipe, changing type of radio, all guides, searched google, this website ( for a whole week ).
Nothing came up.
I'm posting, because this is pretty much last resort. I actually tried the KF1 radio on Miui, devnull, oxygen, and NScollab.
Telus users out there, what is your baseband ? What radio gives you the best signal and performance ? I know koodo switched to KF1, but I can't get it to work on my NS.
Any help is appreciated !
still noone ?
Darn.

I use KB3 for koodo(telus). I get signal... and it works.
I'm curious as to whether KF1 would be a better radio for us, or if it even works for Telus/Koodo. Anybody know?

I have a Telus Nexus S in BC and I just installed an OTA update to 2.3.6 / GRK39F / I9020AUCKF1 and the KF1 radio seems to be working fine. I've been able to call around and MMS without issues so far. (about 2 hrs) Not enough time spent with it to tell you if it gets better reception or not...
I acutally installed the OTA pacakage in order to go back to stock as I was getting sick of the Search Bug that has been plaguing my phone for ages and I was going to bring it back for warranty work, but it appears the flash of the radio to KF1 that was included in the package has resolved the Search Bug!
Sweet! So, I might stick with this for a bit to confirm it is gone and and if all is well, I guess there's no need to return the phone for service!
I have the same issue on koodo. Flashed ICS and I get reception with KF1 downtown but barely anything at home and it used to be great.
I'm running the UCKF1 radio on my telus NS, on cm9 + matrix 14.5. With my phone, it was impossible to flash the radio with CWM, it would flash, but could not get on the network. I had to use fastboot to flash the radio.
In my experience, XXKB3 and XXKD1 were definitely the fastest radios (no upload cap), but my connection was unstable, needing occasional reboots to reestablish connection if I ever lost reception. UCKF1 has been rock solid for me. (I'm in the Toronto area)
Also, for some reason I only started getting the search bug with ICS and XXKD1, but UCKF1 fixed that.

Flash Radio, the ROM

Looking over the ROMs I notice they seem to always say.
Flash radio
Flash ROM
Why the extra step? Last time I flashed custom ROMs and it has been awhile because ..... I am waiting and waiting for ICS, we used to have one zip file and it contained both.

because there are many different radios ....some work better for others .....to prevent a ril mismatch. u flash the modem. then the rom ......the rom flash will replace the ril. of the modem. so say if u want to use a kj2 modem on a ucla3 rom. well the ucla3 rom with a kj2 modem flash over it would yield a ucla rom. with kj2 modem. and kj2 ril. which may cause wacky data issues..........however if u flash modem first.....then flash rom you will have the base band you just flashed ..but your rom flash will give u the proper ril...
i can not guarantee the mismatch would always cause data issues. however with ucla3 modem it does and has been verified. numerous time.......ucla3 modem needs ucla 3 ril
but if your going to use a ucla3 modem and rom.........u may flash the modem first..if your not currently on ucla3 base band.......as long as you know for sure that said rom has proper ril.
---------- Post added at 08:25 AM ---------- Previous post was at 08:17 AM ----------
theres a really cool rom called SILVER_ROM_STI you should check out......and a version that flashes the new ucla3 modem with the rom is being uploaded
ok, so what i get is to flash radio, then rom, so that the RIL from the rom is applied. but what is RIL? i'm using a skyrocket on tmobile network and want to use tmobile roms for the wifi calling feature.
in my scenario, what is the best procedure? i do not understand what RIL is and what it does and what it needs to be compatible with.
what i think is the best course is this, please correct me if i am wrong:
flash tmobile radio
flash tmobile rom
flash skyrocket kernel (is this necessary?)
again , i am using the skyrocket on tmobile network and i want to use tmobile roms for wifi calling. i would also like to be able to access tmobile networks at full speed.
thanks!
RIL is radio interface library, its kinda how your rom and radio talk. The method use just described should work, if you loose datacafter flashing the rom just flash the modem again.

data has been weird lately. speedtest is all over the place and typically doesn't go over 500kbps, but i have no issues browing web or streaming music.. i was attributing this issue to the one that is similar to samsung note users, but they have been patching tmobile radios to be used with the note.. im wondering if radios should be patched for the skyrocket
fyi, i do not know what they are patching.
Is it possible to flash the Blaze 4g radio found here:
http://forum.xda-developers.com/showthread.php?t=1572198
Then flash a rom over it to rewrite the RIL, and see if it works for the i727, or will it brick it?
I'm on T-mobile btw, and still trying to find a good combo. Can't get over 600 kbps DL and over 30 kbps UL

can you provide more information? what rom are you using? i am currently running the blaze radio you mentioned with tmobile tuesday rom with i727 faux kernel. it works. are you sure your speeds are not linked to your location? for instance, at my desk, i see speeds like you... but when i walk away like 50 feet, i get 3mbps.. go figure.
I have tried many combos:
ROM: Juggernaut 5.0, sky-ics
Kernel: faux 9m&u ,10&u
Radio: KID, VLK1, KJ3, LB7 (Blaze)
APN: wap, epc, internet2/3
Isolated 2g and 3g/4g
Everything performed similarly. Right now I'm on Juggernaut 5, faux 10u, and any radio.
I just received it yesterday and I have only been using it at my house so it could be location based.
What I found interesting was when I'm on a phone call and I use the internet, it runs where it should be around 2mb-4mb DL but upload is still weak at 100 kbps UL. Tried it multiple times on different radios, so it doesn't seem to be an isolated incident. Any reason why this is happening?

i wish i knew, but our problems seem in line with that of samsung note users on tmobile. at the end of the day though, it's just a speed test. i have not had problems streaming music (except 8tracks), so all is good enough for me, at the moment..

[Q] ucalc4 modem

I'm a total noob but thanks to XDA, and literally hours and hours of reading I was able to flash the original ics leak from DG, the latest 4.0.4 leak, install CWM touch, and successfully root my AT&T skyrocket. Thank you all! However, I am one of the few that have had better data and voice with the ucalc4 radio despite reports to the contrary. I decided to try flashing LeeC's CWM flashable ucalc4 radio after doing a backup. After flashing the zip and rebooting, i was unable to get a signal. The baseband was also listed as "unknown". I tried putting the phone in and out of airplane mode, reinserting the sim and rebooting but to no avail. Finally, I gave up and restored my backup and upon reboot, lo and behold.....under baseband it says ucalc4!!! 4-5 bars of service instead of 1. Signal Strength -85dBm 14asu (not sure what this means and didnt record settings prior to modem flash) and hspap instead of hspa under phone status!! (No LTE in my area). I'm completely dumfounded now. How did the ucalc4 modem stick, after restoring from backup.??? I would think the default ucle2 modem would have been restored (not complaining though). Sorry for being such a noob and look forward to responses such as..."Post in the right section noob" or "for cryin' out loud, do a search!!"
The radio is not backed up or restored in CWM.

Thanks for the response. So in order to reconcile this for future reference, I would need to flash a radio with no ril, such as the ones posted in the Embryo rom thread?

If you're going to flash radios from different basebands. IIRC you just remove the system folder from the zip
