[Q] Need Help on Nexus S 9023 signal problem

Hi all,
I just got a new NS 9023.
When I got it, the system was 2.3.6(I dont remember if that is official or not)
After some simple tests, I flash the rom to MIUI. And MIUI works fine.
One day later, I want my phone go back to official rom. So I download a 2.3.3 official rom from google.(The link was found on this forum)
Then the problem came - The signal is worse then before. I can't get EDGE, but before I flash the "official rom", EDGE works well. i tried lots of baseband packages but none of them works.
Can someone tell me what should I do now?
Here are some information:
product name herring
hw version: rev 52
bootloader: i9020xxka3
baseband: i9020xxdk1
carrier info: vof
A friend of mine bought a 9023 the same time as mine.
I checked his bootloader, only one different is the carrier info, it is EUR on his phone.

check the IMEI number and see whether it's true or not ?

Baseband seen from system is I9023XXKD1, which I consider is correct.
and signal strength usually between -83 ~ -93dBm both in office and outside.
Also, I found a radio dump bin on sdcard. Is there any way I can use that file?

At the top you say you have an i9023 but your bootloader and radio are i9020. So which is it? Is your problem because you flashed your phone with a stock rom for a different model?

Don't post your IMEI in public. I suggest you remove it. X1111 just wanted to check if your IMEI is changed, but that as nothing to do with your problem. Because if that was a problem, you couldn't get any signal at all.
As I can see, you are surely cofused which device do u have, and therefore flash wrong ROM/Radio. Did you try *#*#4636#*#*? If not try dial it, choose "Phone information", pres menu button, choose "Select radio band" and choose EUR band...
If that doesn't help you, wipe /data /cache and /system in recovery and flash correct stock rooted ROM. Hope that will help...

yes. i have a 9023 device and all 9023 around me have 9020XXKD1 information on boot screen.

Thanks tenhi.
I tried 4636 code and change my baseband to EUR. seems better now. but still not so good. i will keep testing.

This worked for me, at least as far as data goes - in the same place where you choose network operators, choose the option for "access point names" then, when there, if there is no option for Telus, try pressing the menu button and clicking the option for "new APN" then in the fields enter the following:
- Name : TELUS
- APN: sp.telus.com
- Proxy: 74.49.0.18
- Port: 80
And then press the menu button again, hit save, and click the APN out of the list to connect.
That helped when I couldn't connect to Koodo, and they're the same network.
Hope this helps!

Hi, Did you manage to find a solution. I have a Nexus S 9020T and been using it fine under Fido/Rogers (WIthout 3G). Now that I moved swapped SIM to TELUS. it won't detect the TELUS network or connect to any. Any help would be appreciated.

Seeing how it says no radio you probably have to flash a radio for the i9020a, most likely UCKF1.

Please assist.

My dads with telus... put his sim in my phone and no service but my rogers sum is still working fine... weird :S

[Q] No Sim Detected after ROM update

Sorry if this has been covered somewhere, but I read through a lot of posts and none of them seem to be the same thing I am seeing.
I upgraded from the RemICS 1.3.1 to the JB v2 , and now my phone no longer sees any SIM card I put into it. I have tried multiple SIM cards, none of them work. I reinstalled back to froyo, and could see my SIM card. Then I went to gingerbread, could still see it, then I installed this ROM, and the SIM card is once again unavailable.
I have tried using a few different modems, but they do not seem to be making any difference. Any ideas?
This is what I see after I install the JB v2 ROM:
Model Number SGH-i897
Android Version 4.1.1
Baseband Version unknown
Kernel Version 3.0.31-Semaphore_JB_2.0.6sc [email protected]) #55 PREEMPT Wed Aug 22 22:17:31 EEST 2012

Can You repeat the process?

Yes, I was able to repeat the process. I went back to Froyo, then upgraded to GB, then to JB. Same issue.
I also want to clarify, I cleared all cache before installing each ROM. I also tried clearing cache after installing the ROM, but it made no difference. I even went so far as to use the advanced option for formatting the different folders /boot, /system, etc., then doing the reinstall from Froyo, but that made no difference either. I stopped short of formatting the entire internal SD card since I didn't think this was the problem.

Hello mate,
it happen the same for me. I solved the problem following the instruction in this link:
http://www.androidfamily.net/2012/0...g-galaxy-s-gt-i9000-via-remics-jb-custom-rom/
Once you have installed it, you can recheck the sim lock box. It workded for me.
Good luck!

Thank you! I will give it a try adding this step to the process. I am assuming it is the same even though mine is the i897 instead of the i9000. I'll report back on my experience.
Disable SIM lock of your Galaxy S GT-I9000 by going to “Settings > Location and Security > SIM Card Lock”.

I went into Settings > Security > and i see Set up SIM card lock. It is already disabled.

I was able to get it to work. WOOT!
I am not sure exactly what did it, but I think this is it...
Based on the SIM lock not being set, I decided to start messing around with it and I ended up locking the SIM using a key code from the number pad. Woops, didn't really mean to do that, but I was following some instructions on how to unlock the phone completely. Well, the only problem I had from there was I couldn't get the unlock code...I rebooted my phone and did a recovery. However, even after recovery, my phone noticed that something had changed with the SIM and I was prompted for a PUK code. Fortunately, you can get this from the AT&T website. So I logged in, did the code, my phone was now unlocked. I went into the settings and looked and the SIM card was now set to locked. I unchecked the box and unlocked it. Then I did the upgrade again and it worked this time.
Thanks again for your suggestion!

I have a LG Stylo 2 an it's doing the same how can I fix this it's showing no signal an no sim

[Q] HELP! I need to flash a modem if anyone can help?

Ok well, I got my replacement Moto G and everything was working ok on 4.3. Then I decided to manually flash Kitkat through adb after unlocking the boot-loader, and now I'm getting no service at all. lol. Um, yea So I have flashed the same firmware on the original Moto G that I had and had no problems flashing it. I don't know why I'm not getting any service on this one? I forgot to mention that I twent back to 4.3 through adb seeing that might of helped and did the kitkat upgrade after, and nada!
Baseband Version: MSM8626BP_1032.340.63.00b
System Version: 172.44.4.falcon_umts.Retail.en.US

Under status I'm getting Unknown Network, Mobile Network type Unknown, Service State: Radio off, Mobile network state, disconnected, Bluetooth address unavailable. That is what is missing under those sections. I'm assuming it has something to do with the radio/modem. If anyone has one they can let me flash for the Retail US version, I would highly appreciated. :good: Thank you for your help!

maybe a solution

Same issue as OP Help.
I am having the same issue as the OP. I tried to install modem 2 before 1 the way OP stated. But I still cant get any service on my phone. I also have the 1034 version of the device suited for T-Mobile. I tried to flash the stock radio as well but Im not getting any service. If someone knows what the issue is please help.
By the way my wifi is working just fine. Its the network I cant connect to. I tried my sim card and it work in another phone.
Thank you for any help.

I'm also having the same problem. I have a US global model XT-1032 Moto G. No matter what the heck I try to do the radio always stays off on the phone. It worked fine prior to the 4.4.2 OTA update.
I've tried flashing just the modem from the 4.4.2 and 4.3 US firmwares for both the XT-1032 and XT-1034 versions and neither of them work, it always shows the network as unknown and the radio being turned off.
I have even tried erasing the modemst2 then modemst1 in that order and then flashing the modem with the non-hlos.bin file hoping that if I did it in reverse to the normal order it would fix the issue.
The sad thing is that since I unlocked the damn bootloader to do this, now I can't get any kind of warranty repair done on it by Motorola.

I wanted to report that I fixed my problem with my moto-G, it turned out to be a XT-1034 instead of a XT-1032. I posted a blog post with a link for downloading the file that I used to fix the problem. Basically what I had to do was flash the 4.4.2 modem for a Retail GB model moto-G. This fixed the problem. here is the link http://doctorevil30564.blogspot.com/2014/06/how-to-fix-motorola-moto-g-xt-1034-that.html
UPDATE: the Retail US 4.4.3 factory image from here Blur_Version.210.12.32.falcon_umts.AWSRetail.en.US fixed the radio on my XT-1034 so no need to use the previous method if you are having the same issue, just try flashing that version on your XT-1034

No CDMA (GSM/LTE) after typing *#0909# and selecting option in DIAG CONFIG

Hey guys,
I recently bought an old Samsung Galaxy S4 Active SGH-i537 (AT&T) stock Android 4.4.2 - detailed specs at the end of this post.
>>>> This is my problem. <<<<
My GSM and LTE doesn't work any more. The phone says there is no SIM-Card, though I inserted a working Simple Mobile SIM (T-Mobile network). Moreover calling, texting via SMS and mobile data (Internet) do not work. :crying:
It seems also strange to me that the entry in "About Device -> Baseband-Version" is set to "Unknown" (see also below under "Phone Specs").
>>>> What happened <<<<
I opened the dialer and typed in *#9090#. A new Window "DIAG CONFIG" popped up. I selected
1 DM/DUM over HS-USB(*)
in the menu. After that the other menu points disappeared and the mobile carrier icon (http://appcrawlr.com/thumbs/app/icon/86/3336286.png) changed to a no-connection sign (http://www.clker.com/cliparts/2/3/2/5/1194984827960120970no.svg.med.png). When I type in *#9090# the "ServiceMode" window pops up but without any menu items.
>>>> That's why I did the *#9090# thing <<<<
I updated from Stock Android 4.4.2 to Stock Android 5.0.1 (Lollipop) keeping my root-access following this instruction:
http://www.droidviews.com/update-to-lollipop-and-root-att-galaxy-s4-active-sgh-i537/
The installation and everything went just fine. But I couldn't use my Mobile Internet any more, though it had worked on Android 4.4.2 perfectly. So I flashed back to the old Android 4.4.2 and it worked again. I thought there had to be some kind of AWS/LTE-locking in the stock Android 5.0.1 firmware. After some searching on the Internet I came to the conclusion that there has to be a LTE locking on the phone. So I tried this tutorial:
http://forum.xda-developers.com/showthread.php?t=2441211
But it didn't work for me (probably because Samsung locked the firmware). Till then my GSM/LTE still worked!
Afterwards I tried the *#9090# think (I got it from this post: https://disqus.com/home/discussion/droidview/how_to_sim_unlock_t_mobile_038_at038t_galaxy_s4_sgh_m919_sgh_i337/#comment-1604470770) and that was the thing, that made my GSM/LTE not work any more.
Flashing the phone with Odin (same 4.4.2 stock ROM) didn't change the problem.
I know this was stupid.
But please help me. This is my only phone and without it I have no connection to my family and friends. :crying:
Thank you so much in advance! (And sorry for my bad English. I'm trying to improve. :angel

But how? I can not find any modem firmware on the internet, which is for ROM 4.4.2 NE or above.
Anyone with a link out there?

I can not even get there because it says "No SIM". The problem is the modem firmware, I think. But I have no modem firmware for stock ROM 4.4.2 NE or above.

Or google for full factory firmware it come 4 parts
