[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?
and if so, which method should I use to flash radio? The Android SDK one or the ZIP + Bootloader one?

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?!

using same hboot as you, never had problems on flashing radio-files!
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.
but i am woried about stucking on HTC logo after flash :-( and brick it.

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.
http://forum.xda-developers.com/showthread.php?t=1116884 this is radio
Radio UCKF1 (New Version) perhaps you should try this

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

[SOLVED] [T-Mobile] HTC ONE S (S4) 3G not connecting

Need some help for my device [T-Mobile] HTC ONE S (S4). I'm using in INDIA.
For the past 3 years i have used this phone in 3G network with out any issues. Last week i flashed a new ROM but after that i don't get 3G signal.
I tried a lot of ROM's and Radios but still it is not working. So i flashed the stock ROM and RADIO but still its not working. I understand the bands the T-Mobile uses differs but it was working fine before flashing a different ROM.
I don't know what to do.
So please if any one using the same do upload your ROM and RADIO and other things that influence the phone to work.
P.S: I posted in various threads and asking for help but i don't get any reply hence started a new thread so everyone like me can find it useful.
Thanks.
EDIT:
I flashed the Official T-Mobile JB RUU and my phone started to reboot after showing up the "preparing Phone Storage" (soft bricked)
Finally solved the issue:
I have flashed the official T-Mobile JB RUU after relocking the bootloader, S-ON, change CID- ********(Stock cid , In my case its T-MOB010).
Now i have a brand new phone working good.

[Q] APN Problems

Hi everybody!
A friend of mine has a huge problem with data connection.
First of all he has all stock with the last ITALIAN ROM, and when we bought it 2 years ago the phone worked well. The phone is branded "VODAFONE ITA" but in the beginning no problems with it, and he is TIM. He hasn't recharge his credit on the sim for a while and now the data connection doesn't work neither if i put the APN's manually.
It seems that nothing can solve the problem, i tried a restore, to install a stock rom but nothing.
Can anyone help me?
Thank you very much! :fingers-crossed::fingers-crossed:
