Try some troubleshooting first.
Reset your Access Point/Router, or try a different router/ap. Flash back to 100% stock and do a "master clear".
I also find it useful to clear out the /efs partition after returning to Samsung ROMs after using CyanogenMod. Of course ONLY do this after you have a tested and safely stored a backup of your current "nv_data.bin" file. You have been warned.
Take out your battery and just let your phone chill for a few hours. That sometimes helps too.
Anyway, if after a complete flash to stock and master clear, and some troubleshooting with different access points you still get no WiFi signal, something may be wrong with your hardware...
From there you might either need to send it into a Samsung service center, or find a very technically minded XDA member to help you further. Good luck!

[Q] Rooted for the first time, lost any cellular connection. I need a step by step.

So I finally took the plunge today and rooted. I flashed the most recent Sprint version of ViperROM, and everything was going just fine and dandy, I was all giddy setting up my MoDaCo UI mods, etc, until I tried to send a text. Tried to send for 5 minutes, got the fail message. Well, that's weird. What about 3G data? Nope, nothing. Maybe the ROM is bad? I flashed the stock ROM by viperboy, also didn't work. Same problems. So now I'm stuck with no cellular connection and I need it soon. How do I fix it? (Note that I followed my tutorials step by step and everything works except cellular connection. Also note that it says I have service and that data is going in/out, but it's not actually sending/receiving anything. It seems that I need something called an RUU, but I have no idea what that is or where to get a correct one and how to flash it.
Please give me a step by step (I'm using TWRP if that matters), as this is my first time rooting or doing anything more advanced with my phone past advanced themes in Nova Launcher. I'll need links if you have them, or at least where to look. Please help me, because don't want to go back to stock after getting all my awesome tweaks already!
And yes, I have updated my PLR and Profile in the system updates menu, same results.
EDIT: I fixed it, yay! I tried clicking UICC unlock in the software update menu. It said no profile update available, and then it started working (it's actually faster than normal! ) It may have been the profile update that did it and it took a second to update, but it works now! Yay! I even rebooted to make sure it was going to stay after a shutdown, etc, and it did! I guess I should check all option before posting a thread next time... (If you can't tell I'm extremely happy it works!)
EDIT 2: It stopped working again :'(. Now I'm constantly losing the 3G connection that I "had" and messages and data only work about 10% of the time they say they're connected. Wifi still works. When I try updating the profile, it says it could not be updated and to try again later (this is after several tries and a reboot). I try to update the PLR and I get error code 1233. Apprently this is an HTC specific error with no know fix? I try to do the UICC unlock, and it gives me the same error as the profile message.
EDIT 3: It seems Sprint is having issues in my area, I will update again if they resolve it or reply to my tweet.
EDIT 4: They told me to go restart the booster thingy I have in my house, and now my connection is working for now...

[Q] After new radio, prl, pri update, no signal anywhere!

i have had issues before with signal in my area, dropped calls, roaming, no bars, no data, etc etc..
but when i'd leave the area, i'd get perfect signal, 4g, etc etc.
ive complained to sprint many times, and theyve had it working for me off and on.
fast forward to the past few days. i updated the new radio, and tested a few 4.3 roms, updated prl and pri, and i consistantly have zero bars, dropped calls, no data, roaming, etc etc.
ive gone so far as to relock and ruu to the original htc one rom and radio. Still, the same thing.
so i unlocked again, and reflashed the new radio firmware (omj s-off version), and flashed the odex stock 4.3.
still absolutely no signal whatsoever.
heres my specs
revone s-off
unlocked
twrp 2.6.3
hboot 1.44
hardware 0004
radio 0913_3
pri 4.38_003
prl 55016
stock 4.3 odex rom, no mods
im really tempted to rollback to a previous prl and pri, i think thats what has caused alot of my problems.
i can still txt and call a bit, but its really iffy.

Have you updated your Profile also?

yep profile, pri, prl, 0 bars right now, and pretty much anywhere. and ive driven all over tonight late at night.

Same thing is happening to me as well, and Im on stock unrooted, after the Android 4.3 update I have consistently gotten bad signal strength everywhere. Sometimes my text messages fail to send as well. This never used to happen on 4.1. Another thing that has been happening to me that my battery drains much faster after the 4.3 update as well.

omg!! Mine is doing the same thing.. i dont kno what to do eaither.. ever since i updated to the new firmware.. i have 3g its fine but my signal is gone.. i get 1 bar if im lucky when im used to getiing 2-5.. something if deff wrong.. i even tried all 3 radios and nothing.. its gota be pri or prl no? is there a way to go back to what it was?

Same here. I used to get 4-5 bars for my 4G signal at work, and now it's 1-2. Across the board, my signal strength has dropped significantly after the update.

yes you can install the stock recovery image with adb through the bootloader same way you installed you custom recovery
buy the way i'm running the eclipticONE 4.3 rom.

Hey guys, I've created a post in this Q&A section on why this happens. Go check it out

Another thing I noticed is that "Battery Idle" is taking up about 45% of battery usage which makes no sense. This never used to happen on 4.1.2.

No signal of any type
Android Version 4.3, HTC sense version 5.0,Sotware version Stock w Goodies One 2.06, baseband version 1.00.20.0913.3, Kernal version 3.4.10-g18569d8, PRI version 3.17-003, PRL version 00000. Network settings: tried to set to allow access for all trips, keeps resetting to deny data roaming access; 4G settings, nothing; data roaming set to all networks:Network mode- automatic; Allowed domestic voice/data.
Got all that info out of the way.
Flashed CM 10.1 a couple of weeks ago, almost all signal gone since that time. Tried AOKP ROM (the magical unicorns one) no help.
Tried the [ROM]42ONE - Aftermath 2.0, same problem. Today I flashed Stock w Goodies One 2.06 thinking there might be something in the CM kernal (which I believe is used by all but Stock w Goodies). Now I will say that I have always had a really pi** poor Sprint signal where I live, but I was able to sent/receive text messages fairly reliably. Now I don't even have that.
I have turned airplane mode off/on. I have attempted to update PRL two or three time. I have rebooted the phone a couple of times.
Are there any suggestions? Should I try to find another rom? Something's got to give.

Phone doesn't read my SIM

I have been using CM11 (14-03-2014 I believe), without major problems until yesterday. Sometimes my phone seemed to disconnect from my SIM and I had to re-enter my pin code to reconnect to my operators network. But as of yesterday my device doesn't seem to recognize the SIM card, It doesn't ask for a code at all and can't make any connection whatsoever. I didn't change a thing, this problem started out of the blue.
I wiped cache and dalvik, updated to the latest CM nightly (08-05) but that didn't make any difference. In other threads I read about the baseband that might need an update, but I can't check which version I have now because when I try to enter the hidden menu I get the no network connection error. The strange thing is that CM11 has worked with (I guess) the stock baseband.
Is my phone tripping or could it be that my SIM card is broken?
Help and thoughts will be very much appreciated

Try it on stock to be sure about it.

After some searching I found a phone that could fit a regular SIM card, a Blackberry 9900. My SIM worked perfect in this phone, so that is not the problem.
I Also did a complete wipe and installed a stable version of CM 10.1.3, but that didn't seem to help. I hoped that a downgrade would have done the trick. I might try a ICS ROM or the stock firmware, but I kind of lost hope and i'm starting to think this problem is hardware related in stead of software. I'll report back with results on stock firmware and the ICS ROM.
How can I make sure the SIM reader in my phone is working properly?

Sorry for double posting, but I got an update:
SIM wasn't working with ICS so I decided to go back to the stock ROM. However, when I tried to flash V20B.kdz with KDZ_FW_UPD, the program got stuck at wParam=2010 and iParam=210. The phone is now stuck in S/W Update mode, and I haven't found a way to restore it yet. I will argue a little more with my phone when I get back from work, I'll open a new thread on how to unbrick when I can't do it myself.

I have the same problem, and exactly the same error at reflash.
Dead end. Buy a new phone .
I tried to flash it about 80 times. One guy from a gsm repair has a bit luck and make it work at the first, but then, when he wanted to repair my imei, the phone stucked again in S/W Upgrade.

[Q] "Not registered on network" error. *PLEASE HELP*

Yesterday, my phone just decided it didn't want to be connected to a network anymore. I was running DynamicKat ROM. It just happened out of nowhere and continues today. I've tried flashing different ROMS and they install fine, but I still can't register to a network. I believe I need to update the modem, but I'm not sure. I'm currently on baseband version ANK4, but I think I need to update to BOC4. Does this sound correct? Any advice would be great, and if you might point me in the direction of any files needed it would be greatly appreciated as well. No need to link, but just a general section where I could find the files would be helpful as I seem to have little luck with the search function here. Thank you in advance.
EDIT: Ehhh... Nevermind. It just started working again. I can't explain it. Suddenly I was connected again.

Always a good idea to check your APN settings if you are in a known coverage area with a new ROM. Been my problem 90 percent of the time

Funny you mention this as I run the same ROM and have had this occur to me whilst traveling around my area and in and out of T-Mobile "Dead Spots" which seem to be many...
Even called T-Mobile to report and best they could tell me is go into "More Networks-Mobile Networks-Network operators" and select - Select automatically.
A real PITA when you driving down the road and need to call out or re-connect your call with someone.
Note: I've had numerous issues on different ROMS similar to this so I pretty much blame T-Mobile and their service in my area unless someone else can chime in, I would be curious...

I had a similar problem on DK, except that it was unmounting my sim card completely & I had to reboot to get it working again. Happened every hour or so, very frustrating. I tried a different rom & the issue went away, so it's definitely something funky with DK which makes me sad cause that's my favorite rom.
I just reflashed it last night though & I took the precaution of completely reflashing ANK4 through Odin and redoing root & TWRP too, then flashing DK like normal. So far, so good(and it seems to have fixed the battery life issues I was having as well, yay), so you might try that method & see if it helps for you too. But be sure to back up your internal storage first cause odin WILL wipe it. Learned this the hard way, bye-bye all my pictures & titanium backups :/
Files I used can be found here.. BOC4 is for LP, so you should be fine with ANK4.
