Have you tried to flash another radio? Very likely a radio issue.

No, I haven't flash another radio? I tried flash many rom: 2.2.1, 2.3.3, 2.3.5... but they have same problem (lost network signal sometime)
I currently use Darky Rom v10. which radio I should flash?

somebody help me

Did u flash the LATEST radio? If yes, and its still not working, try another one. I recommend anyway, just to make sure, to do a full wipe and reinstall the custom rom.
If you can't still solve this problem, ask in the Samsung forum you will have probably more luck.

Do you think it is hardware problem
I'm afraid it's a hardware problem

it could be.. but first...you didn't answer me..
Did u try different radios? You need to make sure its not an hardware issue!

Sorry for my inconvenience. I tried to search "flash radio" but i can not found any guide thread. Did you mean flash modem? If not,can you give me link to some thread "how to flash another radio" on galaxy s i9000
Thank you so much

Copy the radio on the SDCARD and flash it trough recovery:

[Q] Think I Need Help

I have been searching forever and can't find my issue. I have rooted with the installer kit, flashed LeeDroid, Everything went fine. After reboot my inspire doesn't have Mobil Network. Sorry if this has been answered but maybe I'm not searching the right ?. Been at this for a few hours now and what to be done with this so I can set this thing up. I think it might have to do with radio but iffy to proceed till someone can conform thats it.
Thanks in advance.
Android Version= 2.3.3

Have you checked your apn settings?
Yes just from another post here. Tried with no help. Maybe need a better post.
Try pulling the battery for five min. Then replace it and turn back on. If that doesn't work check the thread for your rom. Make sure that your using the recommended radio with your rom. If it is and your still having the same prob I'd say reinstall the radio and rom see if that helps. I haven't had this problem before and don't use that rom. But just bouncing some ideas around to see if I cant help you figure it out.
First things I would do, check the sim make sure it is in the phone properly. pull the battery. I did notice that you are not running the recommended radio for the rom, you should flash the radio 12.54.60.25_26.09.04.11_M2 as that rom has the ril for it, if that dosen't work, reflash the rom.

[Q] Modem swapping leaves lingering effects

Hello,
I recently flashed the uckj2 modem with red cwm but was dissatisfied with my phone dropping to 3g signals when it was idle. i didn't make a backup of my original baseband file (unless a cwm backup counts) so when i decided to flash back to the ucke3 modem, i downloaded it from the modem file in the dev forum. my problem is that the network time keeps setting itself to 7 hours ahead of pacific time--the auto update on/off trick works for a few minutes but it goes back after that. also, the data dropping to 3g problem has persisted.
flashing to uckj1 fixes the time problem but the not the 3g problem. reflashing the ucke3 modem doesn't work either. does anyone have other suggestions?
thanks from a n00b
From what I understand, numerous people have been having the same problem with the e3 modem. If you read through the modem forum, I believe some people have toggled the auto update of time on and off NUMEROUS times in a row and it fixed the problem but was temporary. That being said, I don't have a solution, just wanted to let u know you're not alone... I haven't skimmed through that forum recently, but if you do, u might find something new that helps. Sorry I couldn't help more...

[Q] Desire S loosing signal

Hi all,
A week ago I bought a brand new Desire S and installed latest CM 7.1 stable following the guide on cyanogemod Desire S Wiki using revolutionary 0.4pre4. Everything was smooth and nice, I flashed ROM and GAPPS and my phone is working absolutely perfectly... but there is one little problem...
I am using Desire to fetch my mails from 2 mailservers using IMAP every 30 mins. But when the phone is switching between network modes i.e. HSDPA -> EDGE or EDGE -> GSM or any other way, I am disconnected from operator network for about 10 seconds until the network mode changes and everything is fine after that, until there is another network mode switch.
This happens for me about 10 times a day, so my phone sometimes appears that It is turned off for people who want to call me. Immediately after connecting to network I get a missed call SMS from my operator.
Interesting thing is, that when I disable email fetching, disable background data transfer and disable network data, the phone works fine without "blackouts".
Can someone help me with this problem? Maybe a radio issue?
Some more info:
ROM: Cyanogenmod 7.1.0 Desire S
Recovery: Revolutionary CWM v4.0.1.4
HBOOT: 6.98.1002
Kernel: 2.6.35.14-cyanogenmod+ [email protected] #1
Radio: 20.28I.30.085AU_3805.06.02.03_M
There is a newer radio-file online.
Maybe it's solving your problem.
I'm using MIUI and never had such problems, but i'm interested in flashing CM, so please report if the problem is gone by flashing newer radio!
Which radio version are you using?
Today I am testing 2G only switch so I am on EDGE data only.
Flashing radios is safe......, but a bad radio flash will instantly brick your phone.
You are using 1.47.401.4 radio, try updating to the 2.10.401.5 one.
Thanks for reply.
Shoud I flash something else with the radio?
I have 20.4801.30.0822U_3822.10.08.04 downloaded from cmw.22aaf3.com
Another I have is ftom OTA update zip file OTA_Saga_S_HTC_Europe_2.10.401.8-1.47.401.4_release_225210fmxlt12djw1sr7y5.zip where is one radio.img in formware.zip file too - version unknown
So Which one to flash?

Both will work, i'm using method by using bootloader normaly
Strangely I had the same issues as you on Endymion.
Then I updated radio to the latest.
It worked well.
Then I went to CM7. It was fine for a while, but now I'm losing signal with no 3G bars and its not switching automatically to 2G like it should when It has no 3G signal!
EDIT:
After really reading your post, I realise my issue is no way like yours! Yours seems really bad. Update your radio.
-------------------------------
Sent from my HTC Desire S
So, here we go with the results
I flashed 20.4801.30.0822U_3822.10.08.04, md5sum checked OK, update sucess, but phone with no signal...
I flashed 20.48.30.0822U_3822.09.08.20, md5sum checked OK, update sucess, but phone with no signal again...
I flashed 20.28I.30.085AU_3805.06.02.03 back, md5sum checked OK, update sucess, but phone with no signal again...
... what now ... ?
After each flash wiped cache and Dalvik...
in your telephone-info there is shown the new radio after every flash?
do you have removed the batterycover, because there is integrated the antenna of your device!

No, the cover is at its place where it should be. Somehow I did the trick and I am back online with 20.28I.30.085AU_3805.06.02.03 on 2G only for now.
I read somwhere in the forum that ENG HBOOT is required for new radios... Are you sure I dont need to flash eng hboot it before new radio ??

in your area 3g is actually available?
may it helps to go outside, to find your net for the first time!
did you set an accesspoint for 3g?
may you have to set automatic settings, rather than 3g/2g-only?!

yes, in my area there is 3g, when I turn off 2g only switch there is a problem described in my first post, so i am on 2g for now just to keep phone connected to network.
main problem is when i am driving and the phone is switching network modes.
so I give 20.4801.30.0822U_3822.10.08.04 today another chance, try to flash if again.

i already had the problem for several times, and i also pulled out the battery (you shouldn't do that)!
only had to boot into bootloader, start recovery, wipe all partitions, flash rom and was having fun again with my device
this thread could help you, if really stuck on HTC logo
For your real problem on loosing the signal, did you ever tried out using actual stock rom, or another custom one like MIUI?
i used MIUI from 2010-08 till yesterday, now trying out CM7.1 for some days
I have the same or a very similar problem. I have the stock rom.
I already had 3 different desire s motherboard's and 2 different display's.
The first Desire S i had, with android 2.3.3, had a excellent signal. Due some problems i had, the phone bricked and had to go to HTC to repair.
HTC replaced the motherboard and update the version of the android to 2.3.5 and ever since the signal caption, the signal switch was working very bad.
The phone went to a second repair because of this, new phone, and again with android 2.3.5. The problems persisted.
I also tested with different SIM cards, from different mobile operators.
So, my conclusion is either android 2.3.5 or this new versions of Desire S have problems with signal caption and signal switch.
So as you, i need some help with this issue!

But when I reboot to recovery it will flash the radio again I think.
i hate stock roms, and dont like MIUI design That is why I am using Cyanogen
Anyway if I use 2G only switch, the phone is stable as rock both calls and data transfer.
EDIT: OK, flashed 20.4801.30.0822U_3822.10.08.04 sucessfully, signal OK, I will see what happens whet metwork mode switches
@Green Hawk:
give us more information about your device please, which radio you're using? Did they flash actual radion also?
@MyroLM:
report if the problem is still there or it's gone with flashing the rom
I am still testing new radio, but looks good Give me some days let you know...
Hi All,
I have a similar problem with the latest CM7.1 nightly builds (Reaper, jorgen2009). I never saw this with older CM7.1 versions, e.g. Nexx version, ICS, MIUI oder Endymion.
I have WLAN on and leave my house. Phone switches to 2G/3G..., so far so good. When I return home, The WLan sign in the status bar appears again, everything seems to be fine, but I have no connection. I get no data via WLan until I swicth WLan off and on again.
Radio is the latest from 2.10.401.5.
Best Regards
Wrapp
Had similar problems, upgrading to the latest radio helped. I got stuck on the HTC screen and I went through flashing RUU's and unlocking bootloaders back and forth... when the only thing that needs to be done is to wipe the cache.
Learned a lot about bootloaders though. But my warranty got void because i did the htcdev unlock... (Sorry for OT)

[Q] Nexus S major reception problems

Dear friends,
I am still new at this. A few weeks ago someone who told me they know how to flash roms would install a ics rom on my Nexus S (I9020A) for AT&T. However since then I have been having extremely bad reception issues. Now my phone might show full bars and signal, however sometimes when my friends call me I don't receive them, also vice-versa. Also my texts won't go through for a long time and sometimes fail, and lastly my 3g internet won't work at all or would be really slow until it connects.
I flashed my phone back to stock (I think.) and I also got a brand new sim card but the problem persists.
If anyone could please help me in describing what might be wrong and what should be done to correct this, please help me out.
Find out what radio you have ( about phone) and try a different one.
Make sure you only flash the radio for your device.
ICS wasn't released for your I9020A officially ... I would not let a friend touch my phone like this lol...
Now..As suggested , settings/about phone : see what version of stock rom and radio are you using now .. and report back
Some people have a debate on what radio is good with at&t and what not ....
Did you do a good clean up before flashing GB back to your phone ? i.e. format system / format boot , factory reset and so on ?
Android Version:
2.3.6
Baseband Version
109020AUCKF1
Build Number
GRK39F
I did do a good clean up prior to flashing back to GB. Would you guys be able to recommend a good radio for me please? Perhaps a link to the thread with the radio. I live in Southern California.

I suggest you also try old basebands like KD and KB.
Different baseband versions work differently in different regions and reception areas.

[Q] Wifi Error, No Bluetooth

So I got myself a Desire S.
Problem is, everytime I switch the WIFI toggle to ON, it would say
"Turning On..."
for a little bit, then It would say "Error", and everytime I try to toggle the BLUETOOTH to ON, it would say the same and just returns to "OFF" position.
Status of the phone before rooting and flashing:
"LOCKED"
SHIP S-OFF
HBOOT: 2.000.20
Radio: .....10.08.04_M
I tried flashing several ROMS including the Kernel(BOOT.IMG) via Fastboot;
Virtous Quattro RC3
Reaper V3
IceColdSandwich 7.5
CM7.1 NIGHTLY
also tried flashing to stock RUU with Radio and HBOOT versions;
Gingerbread 2.3.3 --> Europe and Asia Versions
Gingerbread 2.3.5 --> Europe, Asia, India Versions
Currently on Stock Gingerbread 2.3.5 Rooted through Superoneclick
Until now the issue persists. I'm wifi and bluetooth less.
I've tried searching Google, found some "USB-BRICK" topic on the DESIRE forum, didn't work.
Motorola forum, mentioned a reflash of the Radio.
HTCDesireSForum mentioned a reflash of HBOOT and Radio.
Here in XDA, it mentions that in flashing ROMS, on HBOOT 2.00.20 you have to flash BOOT.IMG from the zip file of the rom via Fastboot.
Tried and failed. I'm beginning to think this is a hardware issue.
Anyone with an idea why or to a solution?
nobody? I haven't found any solutions so far. I really hope someone could help or atleast point me in the right direction
Any updates on your issue?
Have you tried bringing it in to service centers? It looks like a hardware problem.
your issue should just revolve around changing hboot, radio and rom.. I cant think of anything that could affect those hardware..

unfortunately no. I didn't give it anymore thought since I'm using it only for camera and music.
Have you tried the latest radio.. I think its worth a try..
Flash hboot of your choice and the latest radio and stable Rom choice.
I really don't think these hardware break that easily..

I'm not sure about the bluetooth, but I may have a fix for the WiFi.
I have a One S and I started getting the same error when I tried to turn on the WiFi. It turned out that my wpa_supplicant.conf file became corrupt somehow. I just deleted /data/misc/wifi/wpa_supplicant.conf and it fixed the problem.
