One S S4
Hboot 2.15
Radio 1.20
TWRP 2.8.6.4
CM12.1
This was the last working config my phone had before this problem... I tried one night to clean flash a new version of Cm12.1, without noticing that I had ran out of battery juice. Flash failed and phone closed midway through, charged it and rebooted. At first it wouldn't start in recovery, so I flashed recovery again in fastboot. Then managed to flash CM12.1 only to see that it didn't had any GSM signal. During all these operations phone heated as crazy.
Restored to stock using RUU, flashed different radios and roms since then, from ICS with earliest radio to Miui, CM12, Sense 6 etc with latest 1.35, went to hboot 2.16 and back, tried all possible combinations but signal haven't worked since.
Only on some ICS Vodafone RUU plus 1.08 radio I had some rays of hope, GSM signal was working for about 10 sec. after reboot or airplane mode but then nothing. Also, if I could establish a phone call, signal wouldn't drop during, I could speak for minutes without problems.
Could it be maybe nand corruption, some onboard chip failing due to overheating, antenna cable connections loose etc?
PS. Network - Vodafone Romania, SIM is working fine in all other phones I have at my disposal, other Vodafone sims are not working also in my One S. Don't have any other network microsim to try.
I'd check the top back cover and make sure it's in place and that contacts are clean. It really looks like an hardware problem.
An RUU should have fixed the matter.
Phone has been disassembled and cleaned, antenna cable reseated, all contacts sandpapered a bit with the finest grit paper, then cleaned with isopropyl alcohol, contact springs retensioned. I think maybe some issues with mainboard chips or traces...
PS. GSM antenna is actually under the bottom back cover, top one has antennas for wifi, BT, GPS, which are working fine.
From Anandtech review, il looks like you're right. GSM antenna is at the bottom. Did you solve your problem?
Unfortunately, no... waiting for a microsim from a different operator to arrive to test.
MicroSIM from another operator arrived, same issue, can't get any signal whatsoever. Searching for another faulty One S (maybe broken screen), because I can't afford a new phone right now...

Hey everyone been around these forums for a while now, but my first post.
Recently my phone has started acting weird.
I am running
IPL 2.26
SPL 2.26
GSM 2.25.11
OS 4.0.0.0
Using nbd.v7.1.touch.ext ROM,
was also using the Faria WM6 ROM
the issue is that the phone picks up my signal, it stays for a few seconds then and then it loses signal and the phone turns off ( in com manager phone is now off), then the phone turns on (in comm manager) and searchs for signal, and it keeps repeating the same sequence.
I have tried changing ROMS and i keep getting the same thing.. I have no clue what the problem is. I even got a new sim card and still problem persists.
Any ideas?
just a guess.. you have cingular? yea it would be the radio ROM. try the t-mobile 2.19 uk rom.. it works best (in my experiences). give it a try.. you can find the link in the wizard wiki.. good luck
.:Nstefanelli:.
PS.. even if you don't.. give it a try anyway
Will give it a try thanks..
sorry i forgot to say, its a t-mobile rom.. im in canada so my service is from fido..
i'll post back with 2.19 results
Alrite, updated or sould i say downgraded to 2.19 radio.. It seems better, but i figured out why i still get low signal now, my back plate (which has the camera lesn on it) also acts like an antenna, and the clips have broken off on my plate so it is siting lose thus not making proper contact with the antenna pins.
Radio did help imporve signal a little, i just have to find a place to buy that backplate now. Any ideas?

the numbers have no relation to the 'newness' of a radion rom

that's because the little rubber circle, above and slightly to the left of the flash is the antenna.
replacement covers/cases are sometimes on eBay.
hey guys!
I have a bit of a puzzeler on my hands, hopefully you guys may be able to help me out!
I have the Htc sensation 4g from Vrigin canada
A few days ago i noticed that my signal strength was at 0, and i was unable to make any calls or surf the web.
So i go to virgin, and they set me up with a new sim (or three) to no avail.
I then call tech support, and they inform me that, simce my phone is over one year old, i cannot have the phone covered under the warrenty , no insurance me must fix the phone myself.
some information about the phone : I am s-off, running the latest radio (from here http://forum.xda-developers.com/showthread.php?t=1202867 ) on android revolutions's stock ics.
I believe i have tried everything, but maybe i missed something, here is what i have tried:
remove battery
factory reset
new sim
update radio
update ril
update firmware
lift connectors on back of phone to insure proper connection to back cover
try new back cover
remove old sim/sd reader replace with new sim/sd reader
return to stock rom
So that's that, what do you guys think? Do I have a bad radio transmitter/receiver? bad main board?
Every thing else on the phone works, even the wifi and fm radios.
I have noticed that occationally the phone will show a couple bars, but upon calling it says that i am not registered on the network. most of the time the phone reads no signal no network provider under settings->about phone->network
I really appreciate any insight that you may be able to offer!!
Thanks!

So your provider is not willing to help? If you are paying your provider monthly and your device isn't registering on there network I would give them a call. Simply state your device is no longer registering on there network and ask them what are they going to do about it? I would be furious if they refused to help me because device is out of warentee! Sounds like your kind of stuck . You have tried everything. Perhaps give your provider one more call and see if they can at the very least trouble shoot your device. Just because your device is out of warentee don't mean you still don't pay them monthly for service. By chance have you tried a new sim card? Just a thought....I do hope you get this issue solved soon. Best wishes

thanks for the advice, I believe that I will give them a call tomorrow and see if there is anything that they can do for me...
ok guys, I managed to get my phone signal back up and going once again, but it was no easy matter. for those who may happen along from Google or what not, here is the solution:
Buy a sensation with a busted screen, remove guts, place in your phone, re assemble, make phone calls again.
I initially just swapped out the main boards, thinking that the problem was with the antenna connections or something. I put my phone back together and still nothing. deflated.
I took the phone back apart and swapped in the flex cable, antenna connector cable, and the board at the top of the phone. after putting it all back together everything worked, I'm thinking that replacing the top portion of the main board was all that needed to be done; I replaced everything just to be safe.
so there you have it, i hope this helps anyone who stumbles upon this with a similar problem. my problem was a hardware problem.

Hi
I recently did a rebuild on my one s to replace the vibrate motor/ribbon cable & also inadvertently resolved my touch buttons not working
Since then unless the phone is in a very strong signal area (we have a femto cell in the office which it connects to fine) it gets nothing at all - my sim works without issue in other phones so that's not it
I understand that the GSM antenna is in the lower section of the phone, I've checked all the gold contacts and the wire running down from the mainboard to this daughterboard, disassembled and rebuilt etc but the issue persists.
My question is, is it worth going through the radios and flashing to see if thats it - or could it be the replacement part was faulty?
Any advice or things to try would be appreciated
Cheers
hello guys,
finally posting here after serious searching for days as some htc one s models have this wifi issue of weak signals or not connecting at all.
1. I have HTC One S S4 model.
2. Wifi used to connect only to WPA routers within a radius of 5 meters from router. Any router away frmo 5 meters wouldnt be captured by phone.
3. Tried different tweaks on antenna but nothing, checked through the wifi power option in advanced settings too.
4. upgraded official ROM, nothing happened.
5. Finally took the phone apart and changed the wifi antenna pins, resoldered new ones.
6. On these new pis, used the tweak (putting a U shaped wire touching antenna pins and cover)
7. Now, most of the times, it has full signal strength, but just stays on "Establishing Connection" and leaves.
My phone is bootloader unlocked, rooted with HBoot 2.15 and TWRP recovery installed.
The BT and 3G works perfect and fast
Android 4.1.1
HTC Sense 4
Software Versio 3.16.75
Kernel 3.4x
Baseband 1.12.50
Compilation 3.16.75
Please suggest me something... i am starting to have enough of this phone......
Thanks
Did you try flashing the Wi-Fi partition fix?
Sent from my rotary phone
Did you try flashing another Radio ?
I have taken my phone apart a few times I'm not sure what you soldered but I hope you used a low heat when you did it.
I would also take another peek inside and make sure some solder did not go somewhere it shouldn't have gone.
Thanks for the replies guys. I changed the phone with a customer who is almost every time on the move so don't use WiFi usually, I told him the issue and changed with his.
Let me get my hands on his HTC when he is back in town AMS I will try the suggested methods....
Previous information guys... Thx

After flashing CM12 on my nexus 5 (D821). I flashed the 20 jan Nightly and everything was working fine untill i update to the 22nd jan nightly when my 3g simply stopped connecting or had very spotty signal, i didn't give it much thought at first thinking it was a nightly problem but after one week i reflashed stock lollipop, locked the bootloader, even tried kit-kat and the problem is still there. Before flashing cm 12 2g/3g/lte switching was working perfectly for about one year.
So utill now: i flashed different stock rom's, different kernels, radios, custom roms and nothing worked. When i tried switching the sim with another one from the same network, 3g worked on the other phone so i doubt that the sim is defective, but on my nexus i had the same connectivity issues. I also played with the *#*#4636#*#* menu and managed to get 4G working again but only in CDMA mode and I cannot receive any calls or texts, but the internet connection is working, 3G also connected at some point but the signal was very poor.
I am lost now, and also desperate because edge is too slow for anything. What confuses me though is that this seems to be a software issue since the cause was me flashing a different ROM but all the signs point to a hardware issue.
Can anyone plese give me a second opinion? Is there any fix for this? (Also i recently went to my network's service to replace my screen assembly, could also this be an issue? the issue appeared about 2 days after getting it back from them, also about the same time i flashed cm12)
Thank you for your time.
Also another thing i just noticed:
I opened my phone's back cover and the writing on the frame covering the motherboard says D820 and in the bootloader my phone shows as D821. Is this common for every D821 model?
I started to wonder if i got all my components back from the phone service... Although it's highly unlikely that they mingled with the motherboard since everything that i had on my phone was still there (custom ROM and all my personal info) maybe they switched the antennas...
Is the antenna connected?
Im going with disconnected antenna as well.
