[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 ?
system -> about -> status

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.

[Q] Reversing Gingerbread Baseband Flash or Correct Baseband for my Provider

Good Morning,
After flashing the Gingerbread Baseband I no longer am able to register on the network for my provider.
The device is from Rogers but unlocked and being used on the Bell network.
After flashing I realized there may be a different baseband for me to use in Canada (just North of Toronto).
I require some help in locating a Gingerbread baseband that would work or provide me with instructions on how to return to the original baseband.
Any help is appreciated!
Thank you kindly,
- Audi2Audi

Did you set the APN manually? You have to do that.

Hello!
APN in Menu|Settings|Wireless & Networks|Mobile Networks|Access Point Names ?
I have set that to: pda.bell.ca
Is there other steps required though?
Thank you for the response!

apn settings is for internet. phone must tower of sim. may be flashing baseband again will soveit because i am tower getting for my country

If you're wanting to go back to stock froyo first you need to visit here to get your original rom... these will also flash the baseband back too
http://forum.xda-developers.com/showthread.php?t=1246678
or here http://forum.xda-developers.com/showthread.php?t=1155874
then you will need to follow this turtorial in order to flash the stock rom back on (go down to second post that one is in English )
http://forum.xda-developers.com/showthread.php?t=1244490
Although it is a possibility that the BB hasn't flashed correctly, might be worth trying it again... might also be worth trying a froyo rom to see if you get a signal then, because if you do you still have the froyo baseband on...

Thanks adixtra i always forget about the tutorial of yours

You can flash a .Bin File for Your P920 or P920H.

Ok, now this is getting bizarre hah.
I reflashed the baseband again and everything went normal as it did before.
This time I searched for networks and selected my provider. After about 5 minutes of the device trying to register on the network an error was received that said it was unable to register on this network.
However, when I got to my home screen I was registered on the network. I tested a voice call and it worked. I have tested data as well.
BUT! This is where it gets even more bizarre...The device cycles from 4 signal bars to 2 signal bars to none to 3G (from H) followed by not being registered on the network. Then a few minutes later (sometimes only after a reboot) it returns to 4 bars and begins the cycle again.
Has anyone seen anything like this before?
Thank you again for your help!

Good Evening,
Would you be able to upload the KDZ file from your update?
I am having problems with the LG Phone Recovery indicating that I have the most up to date software and halting the recovery process.
Thank you!
- Audi2Audi

Hello,
I flashed an earlier KDZ which allowed me to use the LG Update tool to restore my stock rom.
Thank you everyone for your help and advice.
- Audi2Audi.

it will tell you that but if you use recovery mode and it will download the file then you will have to unplug the phone from usb hold vol+ power then plug it back into the usb and it should download. like i said i used similiar method to flashing baseband

On my windows 7 not detect omap 4 and i can't flash baseband,what can i do?

[Q] Please Help! Using 9020a on T-mobile.

I was currently using MIUI GB build from brainmaster, and I wanted to switch to the ICS after finally finding out they halted the OTA update. Well I'm using T-Mobile, and when i flashed the stock rom back, i was not able to us the 9023t stock rom as it kept giving errors. So i had to tried the 9020a (which i believe is for ATT) and that worked. My phone is able to make calls and receive texts, but it only shows that its on edge (e) and no more 3g on the status bar.
My question is, is there a way to switch the baseband back to a 9023t build? or did i always have an ATT branded phone?
edit:
This is what my phone status shows:
Carrier: Tmobile
Android Version: 2.3.6
Baseband: I9020AUCKF1
Kernal: 2.6.35.7-gf5f63ef
[email protected] #1
Build: GRK39F
Another update:
Just verified after pulling my battery the model states:
GT-I9020T

It seems that you have flashed an I9020A baseband on an I9020T. There have been reports that people who have done this have never been able to get 3G again.
However, you can try to follow this link and flash the KI1 baseband and see what happens.
Just out of interest... do you know anyone with an AT&T sim that you can borrow to see if you can pick up AT&T's 3G now? (you would have to make sure that then APN for att is entered and selected) It's extremely doubtful but would be interesting to know nevertheless...

I will try and flash that baseband, and will update asap. As of right now, I dont have an ATT sim card, but if i do come across one i will update as well.

Also, do you know why it happened to let me install the 9020a rom, and not the 9020t? I had to root my phone from scratch all over again to erase the MIUI rom and to try to bring it back to stock. Every time i tried to install the 9020t/9023 it kept giving me the error message:
E: Failed to verify whole-file signature
But it worked like a charm when i attempted to do it with the 9020a.

I was able to flash the KI1 baseband with no problems at all. Now with this will I be able to flash ICS?

Either flash the official OTA or an ICS ROM that doesn't contain a radio.

[Q] updated to Gingerbread (via Kies)

I've been doing a search to see if its worth updating my stock Galaxy S 4G to Gingerbread via the official update with Samsung Kies.
Does anyone know of a specific list of all the pros and cons to do so?
I've been pretty happy with my phone these last few months, but if the update can truly improve the performance, I'd probably give it ago.
I'm hoping to develop a little game plan for doing so, perhaps updating to Gingerbread, and then rooting the phone to erase a few programs like TelNav.
Any know the best way to root the phone once its been updated?
I'm also curious if anyone knows if the Gingerbread update will allow me to install Skype, because as of now my phone can't even install it (it just reboots with a failed install every time).
Thanks in advance for any advice!

Yes. Worth it. Do it.
Here is a guide: http://forum.xda-developers.com/showthread.php?p=21954884

what about Skype?
Thanks for the links. I will tread carefully.
Do you happen to know if Skype with video will work once the Gingerbread update is installed?
- J

my phone is using a chip from another company (movistar-peru). would there be a problem if i update to gingerbread trough kies? i guess they might have changed the configuration of the phone. any advice?

A chip? Do you mean a SIM card? If so, and you have a Galaxy S 4G - SGH-T959V you can update.

Wont his phone be relocked once he upgrades?

I'm not sure if it will re-lock. If so, he can use FB's unlocker script to re-unlock it.

@migueltr14 as lumin stated if you have that model of phone then yes you can update. Be aware tho it is possible to have to unlock the phone. If you dont have the unlock code I suggest getting it first.
Or you can root the device after and use the method in the link below.

Yeap i have a SIM card from another carrier (Movistar - Peru) i forgot we call it "chip" instead of sim card (smy bad ). The phone has as model number SGH-T959V. Additional info abour my phone:

You can update u just may need to unlock the phone(not root) since its a tmobile phone on a different network

Oh thanks for the infor!, but when you say that i might have to unlock the phone, you're talking about paying for a web site to give the code or there's another way of getting it?

You can go that route. Or if you root the phone the link in my previous post will tell you how to get the code yourself.

Thanks a lot!, i updated my phone, SIM card works fine (didn't need the unlock code)

[Q]ProbelamticSU 760

Good day. I've been scouring the forums for a week now and I have a fair grasp of which guides I should follow. However,I have a limited technical capability to fix it and a fair share of knowledge through reading. So if there's any of you who can pitch in some ideas,I'd gladly appreciate it.
Situation
No Wifi
On Froyo 2.2.2
Has Signal Issues
No bluetooth
Functional Phone
[/LIST]
History
I acquired an LG SU760 phone which has been,at the time,on Gingerbread. Can't tell specifically the details but as far as I can recall,
it had a CWM recovery on it.I believe it was also rooted since I saw a SuperSU app.
Upon learning that the unit can be upgraded to ICS, I wanted it to be reverted on official stock GB,and then,later updated to official ICS thru OTA.
So I had the unit sent to a "TECH GUY" who apparently failed miserably on fixing it.Instead,leaving me with the unit with the issues above.
From what he told me,He apparently flashed or used a p920 rom,then failed. Soft bricked the thing. Downgraded it to GB. Updated it to ICS port,but got the Camera inverted and the 3 soft keys messed.Reverted back to GB with intact wifi and bluetooth. Noticed it consumed too much phone memory.And then finally settled into downgrading the thing to Froyo 2.2.2. Now I have a LG SU760 on froyo 2.2.2 with no WIFI, no BLUETOOTH, significant signal issues,no mobile internet connectivity,and a functional camera.Pretty useless if you ask me.

How can I flash a baseband?
How can I fix the IMEI?
