[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.

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] 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.

Wifi problem
Dear XDA!
I'm a new member in here. I downloaded softwers from here.It's working correctly. Yesterday I upload the Fallout 4.3 software then the wifi connection is failed. I try another software Nik Project X and the problem was the same.
Somebody could help me?
Thank you!

Open your own thread. Don't jump on the end of someone else's thread unless you are contributing or you have exactly the same issue - which you don't.

Is there a solution for the WiFi issue?

It's been some time since I posted the problem. I searched around and didn't find any new information, so I am just hoping I missed something, like a possible thread that has a fix.
I have no WiFi, have gone through the book trying to fix it, to no avail. HOWEVER, I left the phone un used for about a month, battery had died long ago. A few days ago, I grabbed and and just decided to give it another shot and install revolution hd on it. For whatever reason, it installed successfully and the WiFi was working perfectly. So I updated the 4ext and had notice that a new version of HD had come out, so I decided to update it, and well, back to square 0, WiFi no longer works. So I tried to back pedal and repeated the steps leading up to the WiFi working, Super Wipe with smart flash enable, reboot, installed HD with no smart flash. But this time it did not work. Strange that it worked before though, I wonder if it being out of battery for so long had something to do with it.

did you try to flash the boot.img of your rom?
also if you are S-ON when flashing a rom always enable smartflash

I too had the wifi issues for quite some time. After updating my kernel it got fixed.
Probably you could do the following:
1. If your HBOOT is S-ON, make sure you follow the above two posts while flashing ROM
2. Ensure that the latest firmware is being used.
2. Try changing the kernel (mine is faux 009b4 now).

I am S-OFF, like I said, I've tried everything.
Just seem odd that out of nowhere it flashed correctly, I should of just left it at that, maybe if I leave the battery inside the phone drained for a while I can repeat the successful flash.

well don't know if you have tried this but the last thing I can think of is to go back to stock ruu, if it still doesn't work it might be hardware related

I faced with same issue. I use ARHD 6.7.1 and i have no problems with wi-fi , but when I try to install sense 4.0 roms for sensation, I always have wi- fi problem.I live in Almaty and I use Beeline for mobile carrier, My device is Revolutionary S-OFF. I live in Almaty and I use Beeline for mobile carrier, and also I have one sim card for Turkey, AVEA, when I use Beeline wi-fi doesn't work but when I use Avea wi-fi works completely. I tried wifix manager. But I can't find solution :/

Same thing happened to me when I updated, go to tools in 4ext before flashing and enable smart flash, I'm pretty sure this will help

[Q] Hboot 2.15 and wifi probs

Hi all!
After ditching my Desire HD, I bought myself a HTC One S for its faster soc and better screen.
As I was used to having everything working on my former phone I'd expect this for the One S as well..
So far I've reached Unlocked bootloader, SuperCID and S-Off. Still on HBoot 2.15 though.
On PAC-man Rom at the moment and experience some Wifi problems as its not connecting to all wifi networks, yet some of m work.
Tried all sorts of radios from the Development forum, Sense version, Temporally version and CM version. None seem to take effect.
Tried some different Kernels as well, same outcome..
Tried ViperRom (with and without update) this morning and Wifi isnt able to switch on, even after different kernel and radios..
In short... is there a way to get all types of Wifi working on AOSP or Sense rom?
Is it neccessary to downgrade HBoot (as there is bricks reported)?

I'm on 2.15. S-off. Super cid. But I never had wifi problems. Have you tried the wi-fi fix on the radio thread?

I have not found a seperate file tot flash or push for wifi fix, so i presume it is incorporated in the aroma installable radios.
Wat ROM are you on?

OK. Here's what I've found out..
Since I'm really anonoyed by my phone not connecting to all types of Wifi I flashed an RUU.
I did this during SuperCID and S-OFF and just ran a .exe RUU.
First one I tried: RUU_Ville_U_HTC_Europe_1.09.401.1_R_Radio_0.14.3059.14_2_release_243825_signed.exe
It had no effect, booted up, yet Wifi was not fixed.
Next one I tried: RUU_Ville_U_HTC_Europe_1.53.401.2_Radio_0.15.31501S.19_10.12.31501S.06L_release_251412_signed.exe
And voila my Wifi worked.
On Hboot 1.06 now, flashed recovery and next PAC-Man ROM v20.0.0.
Now my Wifi again is selective like it was before.
I hope someone has an idea where to look as I simply don't understand what the problem is..
Tried the Temporary Radio V2 as well, no effect.
Anyone?

In the developer forum there is a radio thread with the WiFi fix.

Have you tried switching your hboot around?
http://forum.xda-developers.com/showpost.php?p=38387544&postcount=148

Thanks for the hint.
However something I found out was that the new version of VenomROM V2.1 does give me full Wifi.
Unfortunately I don't realy like Sense Roms and rather have a different one.
I redownloaded PACman v20.0 and have tried all Hboot versions, none seem to make an improvement on Wifi capability.
Some work, some won't..
Going to try one or two Hboots with different Radio's from Temp Radio installer V2.
Anyone got an idea? Or perhaps a nice Hint again

[Q] HTC One XL GPS Problems 4.2.2

Hi, I was previously running Android 4.1.1 Venom XL ROM. I saw 4.2.2 Venom XL and decided to upgrade. The upgrade went smoothly, but I have two problems
GPS:
As soon as I reboot the phone everything works. After a few hours, suddenly the GPS will not work anymore. When you bring up programs that require GPS like Maps/Waze, it will not even look for satellites (no GPS icon shown). Once I reboot, things will be ok for a little while. I tried installing the GPS Status & Toolbox App and even when I open that App, it is the same behavior. It works after a reboot, but the GPS lookup does not happen after a few hours. It is big problem for me since I moved to a new state only 4 weeks back and have been highly dependent on the GPS to take me around. Anyone face this problem and have any suggestions? I tried the different options the GPS Status & Toolbox offered but none of them helped. Thanks for your help. Never had any issues with 4.1.1.
Weak signal:
I have seen suggestions of installing BeastMode Kernel or update the firmware to fix this problem and am yet to try this. Do I need to be S-OFF to install the kernel?
My HTC One X is rooted and I have supercid, but it is S-ON.
Thanks for any help in this regard.

No, you do not. The kernel solution is a good option, if you do not have S-off.
Although you should consider s-off, as its easy to do (especially if you already have adb set to go) and gives you more options for recovering (if you are SuperCID and S-on, a Jellybean RUU will brick you). As long as your understand that s-off means all security checks are off (and you therefore need to be careful of what you flash) s-off can be a very good thing to have.
Also, your GPS issue may be related to the signal issue, so kernel or 2.15 firmware fix might solve this as well as your weak signal issue.

Thanks. I did S-OFF, installed the new firmware, reflashed viper xl 4.2.2 rom and I am back in. So far so good. I hope GPS works ok. I was trying to download the latest 4.2.2 beastmode kernel form the following link:
https://www.dropbox.com/s/m53u563v2ql3818/beastmode_tester2.zip
posted on http://forum.xda-developers.com/showthread.php?p=45089267
Is this the official BeastMode kernel for 4.2.2? It says tester and that is why I ask. Also, I see no specific instructions of how to flash it. Is it just as easy as copy to sdcard and use recovery to flash? Can anyone please confirm?
EDIT: Found the updated link http://nosroms.com/?developer=Evita. But, if someone could still confirm the way to flash the kernel, that would be great.

Wipe cache/dalvik and flash kernel via recovery.

Thanks. All set now. Looks like my GPS is working great :victory:
I hope that my the kernel does its thing and no signal drops.
Thanks for the help.
