[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)

Suddenly extremely poor reception

I'm having major issues with reception in my house, and only on my 16 GB OnePlus One. When switching to my Windows Lumia 635 or my HTC One X+, I get fine reception-- but as soon as my SIM's in my OnePlus One, I start receiving texts extremely late, which is a problem with apps like WhatsApp which require text verification.
I'm running stock ROM. That's CM 12.0-YNG1TAS17L. Stock kernel, unrooted even (ever since I flashed it back to stock to try and fix the reception issues). I've also tried OxygenOS, BlissPop, and Exodus and none of those have fixed my reception woes. Thanks in advance!

You ever get this fixed? I recently took a trip to San Diego and noticed the poor reception there.. a friend of mine, who's also on T-Mobile, has excellent reception with his new HTC One. I, on the other hand, had horrible reception; sometimes none at all. I've manually flashed the latest radio and still no dice.

Yeah-- here's what I did:
1. Flash stock ROM.
2. Update to latest stock ROM version via the CM updater.
3. Install TWRP again if needed.
4. Followed steps here: http://forum.xda-developers.com/oneplus-one/help/fix-cm12-calls-sms-mms-deep-sleep-t3103193
I flashed both the modem and proximity packages after updating to latest stock, and I reflash every time there's a new stock update. Hopefully this works for you!

Wait, isn't the stock from still on 4.4 or something? How does that fix 5.0+ issues? Anyways, I'll give it a try, can't hurt, right? Thanks, I'll let you know how it goes.

Well, stock is 4.4, but when you use the stock CM updater you'll be brought to CM12, 5.0.2. You don't have to stay on 4.4

(Though presumably you could just try flashing modem and prox packages without flashing back to stock-- I just wanted to be sure as possible that nothing would interfere with the packages.)

Flashed an old backup of stock, baseband stayed the same. Also, when I check for ROM updates, it says there are none. Currently on 4.4.4

oneplus one 3g??

Hello all,
I have OPO 64gb and I am using cm13.1 official with stock kernel and I am unable to connect to 3g. The phone works fine in 2g with data. But as soon as I select 3g I lose the network even with *#*#4636#*#* command. I have tried radios of 44s, 241,33R but nothing works. Any solution?

If you are indeed using CM 13.1 you should leave that Problem to the pre-alpha Developers and use a snapshot-build of the the current Version which is 13.0.
Otherwise you need to provide more details.

updated: [solved] CM13 No signal (cell or data) after flash, backup wont restore.

I had a nightly of CM13 working, but the SD card wasn't working correctly, so flashed the 20160820 snapshot, and everything was good except there was no connection to the sprint network. Wifi was OK. I tried flashing the latest nightly (20160930), and same issue. All downloaded from the CyanogenMod website.
So gave up and tried restoring the backup but it has failed, sdcard issue.
Tried the snapshot of 12.1 but it just bootlooped.
Edit:
So I tried flashing the 12.1 snapshot (20161001), still the same.
Edit:
I flashed this stock rooted - http://forum.xda-developers.com/spr...ment/rom-g900ppca-6-0-1-stock-rooted-t3387717 and got cell signal, but data only for a few minutes.
Any way i can get cell and data?

what version of TWRP are you using and what baseband are you on?

Thanks for the reply. I ended up reflashing the stock Deodexed rooted ROM and the cell signal came back, so at least I was able to make calls.
I was about to try an old Lollipop ROM, but saw the latest comments on this Resurrection Remix thread all seemed happy, with no issues, so late last night flashed it. So far this morning I haven't seen any problems, I have cell signal, LTE and the SD card seems to be working as intended. Wifi is good too. Just need to checkout Bluetooth and even that's not essential. Will play with it today and see. So I think I'm good for now. Again, thanks for your reply.

[q] need help with no service and no mobile network available

I have no service and no cellular network problem on my N5, running dark rom 7.1.2 aosp, with franco kernel ( never had issues before ), newest radio and bootloader. This started happening when i got my new sim card from my provider and i got 4g signal in my area for the first time. I tried manually selecting radio by going in the hidden menu by entering *#*#4636#*#* and i got lte and full bars signal after selecting band 8 ( 1800 hz ) but only for a minute then it went back to empty triangle. Tried selecting 3g only in preffered network, tried manually selecting provider, tried toggling airplane mode on/off a bunch of times nothing works. Any suggestion would be highly appreciated, i love my N5 very much and i would hate to throw it in a drawer somewhere. Thanks in advance

Flash back to a stock ROM and test it worth your new new.
Does the sim work in another phone?

Were you ever able to get this rectified? I have recently been having this problem as well. I have flashed back to ROMs I was previously using and flashed back to stock to no avail. My SIM card works in other devices as well. I really do not want to have to drop on a new phone, but I have tried every solution I have found online to no avail. I think it's fair to say that I am desperate right now.
edit: I found another thread on XDA that I'm looking into, I'll edit again if it works. I'm unsure how it took me so long to find that thread.
edit2: https://forum.xda-developers.com/go...getting-cdma-networks-to-nougat-roms-t3534679 is the thread that I found useful; I am now running Pure Nexus 7.1.2 with a full connection. Specifically, his second comment about installing 6.0.1 stock, backing up the efs, flashing the desired ROM, then restoring the efs is what ended up fixing it for me.

No luck with aosp by santosh m and pure nexus 7.1.2 , can't even get it to connect. I guess my last hope is caf based i will try lineageos caf. All i need is the efs backup from stock? If i can get it to work with 3g i will be satisfied because i did some digging and found out that my network provider which is Vip MK has no lte support for nexus 5 d820 ( my model ) only 3g, but i can't even connect with 3g selected. I guess because this one is for US frequencies it will not work whatever i try but i will give lineageos caf a chance.

I was able to get 3G only to work on my Nexus 5 by reflashing the EFS from 6.0.1; I'm trying right now to see if I can install PureNexus 6.0.1 then dirty flash to PureNexus 7.1.2 with any success. Also, I might just switch to T-Mobile, but I have to wait until later this week for that.

Hi,
LTE band 8 is not in 1800 MHz but first of all you can check your N5 model - US model is D820 and is not supported for LTE on 1800 MHz (band 3). For 1800 Mhz band you need D821 model.

To clarify that:
You had the problem with not recognizing the sim or having no service at all. And you solved this by flashing the sstock 6.0.1 backing up the efs, flashing to Pure Nexus 7.1.2 and restoring the efs immediatley after flashing the rom (+kernel+root+etc)?
This solves this mysterious no sim/no service bug, which many (?) N5 owners experience? If this is true, I'd be really happy

It didn't stick. After I lost it I was unable to get it back. I gave up and switched to T-Mobile, where it is no longer a problem. Apologies for not having more testing information. I was able to get solely 3G on multiple instances, but getting the elusive 4G was beyond me.

I've had this problem before in two nexus, one of them running latest stock and the other a customized ROM. I tried to flash a stock ROM image in both of them with no luck. I was pretty sure that the image I was flashing was the latest, so the radio & bootloader should be flashed to the latest versions. But it didn't worked.
Finally I found on a XDA thread where someone was posting only the latest bootloader & radio to flash. I did it with NRT (in Advanced Utilities) and it worked:

I can't remember or find the thread, so I post the images here:

- Radio-hammerhead-m8974a-2.0.50.2.30.img
I think I had to flash them twice because the first time it wasn't right, but there were 4 months since then and still no failure

Thanks for your input. I'll check that when I have some time. This is really weird as it looks like a hardware problem but if you can fix it with this method it's clearly a software issue...
