I rebooted my device, and suddenly it didn't get any signal
I have the sim card inserted, and it says No signal.
Any way to fix this?

Did you pay for and activate the service? Just asking as your not providing much information.

Well Yeahh;;
And to add, this happened before, but it strangely dissappeared when I flashed a different kernel.
And it suddenly happened again. I have no idea what is going on;;

Ahh okay so you're flashing kernels no wonder you're having issues. Have you tried returning to stock?
Here are the things people like to know to help you:
Are you running a stock or custom ROM, what kernel are you using, is the sim a true micro sim or one you cut down to fit, who's your carrier. When this first happened did you do any modifications to the phone or was it completely stock? There could be any number of reasons why this happens and the more info you provide the better the quality of the help you receive.

I didn't, but the first thing i tried was to backup to original stock state it was in like 2 weeks ago. Still had no signal issues. But I know that the hardware is not broken, because it fixed itself before somehow. I don't know what I did though;;
I am running a xylon rom, and I was using a clemsynExtreme battery saver, and it is a true micro sim card. I have tmobile, but using a unlocked google play store n4. When this happened, I first had a matrix kernel with the xylon rom
Were you playing around with your APN settings?
Here are some reason I can think of why you could be losing signal:
1. a buggy custom ROM
2. a buggy custom kernel
3. improperly cut sim card
4. wrong apn serttings
5. flashing the wrong radio, I believe this will cause a brick more than just losing signal
Typically when **** just keeps going wrong for me I just revert back to stock and start over. This is either done by restoring a nandroid backup I've made, preferable as I don't like to go fully back to factory stock very often, or if you don't have one by flashing the stock image (restores back to factory condition). I would maybe go into the thread for the kernel you are using in the development section and see if anyone else is having the same issue before going nuclear and restoring a stock image.

The battery saver could be your problem as it most likely turns off your radio when not in use to save the battery. Also go into the xylon rom thread and the matrix kernel threads and do a search for signal loss and see if any one else there is also having the same problems. Not sure if you can post in development without 10 post here first but you're on your way.

Wait a minute clemsyn is a kernel, does he even make one for the Nexus 4? I would image your problem is kernel related. If you made a backup of your stock image I would just restore that first through recovery and go from there.
---------- Post added at 08:40 PM ---------- Previous post was at 08:28 PM ----------
Did a search in development and other people report problems of signal loss with some versions of that kernel. Try flashing a newer version, not sure why I didn't think of that earlier, but I haven't had any reason to flash a kernel in a long time as I gave up on the whole custom thing a long time ago. Same goes for the ROM if a newer version of the kernel doesn't work. these guys are constantly working on these things and things break between versions, they are always a work in progress and things are always breaking and being repaired.

From what I am looking at, Clemsyn is a nexus 7 kernel. I think i flashed a wrong kernel??? wow, but it didn't cause any problems when i flashed it into the nexus 4. Worked fine for ~week

Kernels can work between different devices usually with some modifications done for screen size and resolution but they need to share hardware, cpu in particular. You get in to real trouble when you flash radios from different devices, that will brick it solid.
I would try flashing the latest version of the matrix kernel and see if that helps.

Try toggling airplane mode on and off and see if it comes back on.
If not restoring a backup or flashing the system image may be your only options left.
If you think you made a backup earlier go into recovery, (I'm assuming you have a custom recovery installed) make another backup just in case even though you have no signal its just good habit to make a backup before you do any thing then restore the previous backup. You don't need to be on the pc to do this if you installed a custom recovery, you just need to boot into it. If you used a toolkit then I guess you need to be hooked up to a pc.

I tried restoring to the previous backup. This was just rooted, no custom roms or kernels. But custom recovery.
I don't know if there is a way to fix this. But, the thing is, it was being exactly like this, but I got it fixed somehow. I rebooted after failed attempt and it randomly had signal;;.
After that, I tried flashing a kernel, and ever since it has been no signal

Well, the signal worked fine before, I don't know if setting the APN can help
What I am saying is just make sure that they are the correct ones for your carrier as that could be the cause of the signal loss.

Its a hardware thing. Had it a couple of weeks ago after running with the phone. Eventually worked out after removing the sim tray, reposition the card and put it back.
i have noticed the same issue after shutting my phone off and turning it back off sometimes. no signal or takes a while to connect. i have to restart my phone and it seems to go away. i am running stock rom so i think its a bug in jelly bean.
Did you try taking out the sum card and putting it back in?
Ok, I did something really really stupid....
I had CM loaded and used the latest TWRP. I was checking out Clockwork mod, and without even thinking I tried to clear the cache. Well, this locked up my phone and cleared out all my phone data. Odly enough, all my apps are still installed and settings but looks like the SDCARD data is gone and sound doesnt work.
I cannot copy anything to the phone and I need to somehow clear this up and get my phone rooted and functioning again. Ideas???
Thanks!

I have a backup of every cept for say a few pictures. So not worried about that. Just want to get my phone going and if that means reverting back to stock first, so be it. I just need things to be working soon.
Would clearing the cache with Clockwork while the ROM Was flashed with TWRP mess things up like this?
No you cleared more than that on accident..lol..well I would revert back to stock and go from there

Well, was able to boot to stock recovery, reset, boot to Clockwork and then push a Clockwork ROM to the device. I then was able to get in to my phone. All data appears to be there as well so that is cool. Odd and weird.
Odd. Clearing cache wont erase your data right?

Nope. He must have accidentally wiped something else.
Hi, it's my first time posting so I do apologize if I posted this in the wrong thread.
So I recently flashed the latest CM12 Nightly Rom for my S4 I9505. But I realised I needed to restore my backup (which I did with Nandroid before I flashed the ROM). So I went to CWM Recovery, tried to restore with the backup I did.
Everything was fine until I got this : "Error while restoring /system". I thought maybe the one in the phone was corrupted so i copied the one from my PC and still i get this error.
I'm hoping someone can help me on this.
Thanks!
just follow the following steps
1. full wipe data+dalvik cache
2. copy your backup to pc
3. open nandroid.md5 in notepad
4. delete everything and save it
5. now copy the backup to sdcard and restore it.
Enjoy
Hit thanks if I helped you.

Don't be.
1. Reflash stock Rom via ODIN, root and custom recovery.
2. Flash Custom ROM then again. But don't restore the backup you did before.
3. Done.
I may be wrong , but I have restore nandroid backup of stock roms many times.
I didn't even faced a single issue.

First, remove your Google account (no big deal, you can sign back in in a few minutes). Then, go to Settings>Apps>All> Scroll down to the G's until you get the first thing that has Google in it's name. The first one on my phone (galaxy nexus, CM) is called "Google Account Manager". Click on it and hit "Clear Data". Repeat this process for everything Google in the list. Now sign back into your Google account. You should never see that message again!

I'm trying to do as you said, but the problem is the message pops up again the moment i dismiss it, and i cant even do anything else (only able to switch the phone on and off). And I also notice that some apps are starting to crash too.. is it possible to first flash an official Stock Rom and then do a restore?
maybe or maybe not
but I will suggest u to restore it once again and then do a factory reset , maybe it will work.
restoring it after installing stock will be always an option, but can't guarantee that you will not face the com.gapps.... has stopped working error.
.
---------- Post added at 12:10 AM ---------- Previous post was at 12:10 AM ----------
r u recieving this single error or there are more apps crashing
?
This error and also error messages for some of the apps that say the apps stopped working.
I'm just worried that the backup is corrupted (Praying hard that it isnt the case)
Oh btw I'm using a CWM from ROM Manager version 6.0.4.7, I did some reading and they say there's a chance that it doesnt work well with Samsung phones. Do you think I should use another?
there is one more option also, which I think may work
just download gapps package from the given link and flash it using recovery
make sure you choose the right package as per your android version

I used the Moto G5 toolkit I found on here to root my phone (it's been forever since I last rooted, and it seemed like a simple, fast method), and I backed up my phone via the android backup option. It saved as a .ab file, is it possible to restore my phone to what it was before restoring/rooting last night (pre-root)? Skimming around, it's looking unlikely. Is there any way to get my phone somewhat back to what it was before? Unfortunately my grandma was signed into my account on an old tablet I gave her, and her stuff backed up via google, so I'm out of luck in that department.. Any advice is greatly appreciated!

never take the easy way out unless have n idea what it does, adb restore backup.ab
i assume that backup is only apps n data doh so if don"t work would need flash a stock rom from here

is it possible to flash over my current rom without messing it up? i have a feeling the answer is no lol. at this point i've kind of started over, but if i can get at least my texts, photos, etc. back, it would be awesome. just not sure, the backup file is only 83mb. i didn't have a lot of pictures, but something tells me that's not what it has on it.

Hello,
i seem to have badluck this time with custom rom and development for this device. Last i was struggling with encryption problem (when the great @DarthJabba9 showed me the right path) and now a strange thing happened.
So when i successfully booted into xiaomi.eu (latest) first time without encrypting my recovery function, everything was working fine and good, until i installed whatsapp provided all the permissions then suddenly it didnt look for my backup and acted like there was no backup (i nearly got a heart attack) and after setting up the name and so, i got to know it cant create backup, nor do anything which involve the use of internal storage because it is not writing nor reading internal storage, then i backoff and flashed back 11.6.0 stable, whatsapp start working normally, tried again with other xiaomi.eu and miglobe versions - failed same result, whatsapp only working in stable 11.6.0 and not working in other roms. Also, search function didnt work for me this time (so i found out i am the only one with this problem). does any body has a fix other than telling me to unsinstall, reinstall, clearing data etc.
- except whatsapp everything is working fine (TILL NOW)
Oh....please.....nobody has a clue???

You can try a modded whatsapp like Fouad whatsapp. It might solve the issue + extra goodies. Search it on web.
Make sure you backup your chats before uninstalling the app.

Whatsapp does not block you if you ask for otp multiple times in a day. It will restrict the sms for some hours after three attempts i guess, after that you can get it via call. Four times is enough for a day.
And having my number would not help as I wont be giving you the otp.
probably you use deep clean and erase the WP data.
