Try doing a complete wipe and then restore your nandroid. If S-On....flash the kernel last.

I guess the key is will it hold that setting through a reboot. It's something I seem to run into alot porting from the One S.

[Q] No network signal, cache seems to have failed

I jumped the gun and tried flashing the 4.4.1 .zip for the N5 found here: http://www.droid-life.com/2013/12/05/download-android-4-4-1-update-for-the-nexus-5/
It flashed fine, so I then proceeded to wipe the cache/dalvik. This is where I ran into a problem. It sat there, stuck in the process of clearing the cache. After 5 minutes, I turned off the phone out of frustration. The phone booted up and began the "apps optimization" bit that you get after updating. Then I went to sleep. When I awoke, I noticed my phone wasn't receiving a cell signal and I thought, no biggie, cell service isn't very good in my house anyway. When I got to work later, I realized this was a problem. I can't receive a cell signal. My next thought was to flash the new radio to see if that fixed the problem. Well, I can't download anything onto my phone, nor can I transfer from my computer. It says that my storage is full, yet I can go to storage and see that I have over 5 GB of free space. Astro does not recognize that I even have internal storage.
Does anybody have any suggestions? I was just about to perform a factory reset but thought I should check here first. Any help would be greatly appreciated.

Ppl are getting lower signal, but is the signal dropping? Emergency calls only?

Just had the same problem. In TWRP I went into the advanced wipe option, wiped only the cache. Then I flashed the radio. It is working again.

The problem was worse than that. There wasn't any signal at all. Not even possible to place emergency calls.
Anyways, I flashed the factory images which fixed the problem. I then proceeded to flash 4.4.1 and so far so good.

[Q] No Network Data After Flash Custom ROM

Kind of long, but it's just a difficult explanation, please read and try to help me. Thank you.
Okay, so I have a really weird problem, and I can't seem to fix it at all. I rooted my T-Mobile Galaxy S4, and had no problem with data loss, then I flashed Darthstalker, and everything went fine and it flashed but then I noticed that whenever I shut my screen down when I was on anything other than E or 4G LTE, the phone would lose network signal, but what was weird is that I could still receive texts and phone calls. In order to get the signal back though, I had to go change the data type, and then change it back to normal.
So, then I read that wiping the Dalvik and the regular cache would fix it, and it didn't. Then, I also tried flashing a different ROM (Wicked v9.1) which also didn't fix it. So, I flashed the stock firmware and just got rid of the root and the problem was gone. I even tried rerooting and just installing only Wicked first just to see if maybe Darthstalker corrupted something. But, it still had the same issue, so I just went back to stock again.
Can someone please help me fix this? I've looked everywhere and I can't really find anything to help me out with this.
Thank you in advance.

[Q] Any way to recover data from my unrooted Nexus 5 after sudden factory reset ?

Hello,
My nexus 5 device running on android lollipop 5.0.1 suddenly performed a factory reset. I'm been searching for about 2 hours and reading articles about how to recover my valuable lost data. I want to know are the windows based apps that claims that they can recover my lost data worth trying or buying or there is no hope ? also if they works, will they work on my unrooted device ?
I Appreciate your help a lot
Regards,

Moto G (XT1031) No Data 5.0.2 Upgrade

Okay, I've got a boost mobile moto g ( xt1031 ) that was flashed with 5.0.2 from 4.4.4.
I'm not exactly sure what happened, but after a wipe and re-flash I've lost all data connectivity.
3G icon shows at the top still, signal strength still shows full. PRL and Profile update correctly..
Yet there is a "!" over the signal bar.. and no data connectivity.
I've sense flashed back to 4.4.4 ... Same problem.. Everything shows having a connection.. 3G icon.. Full strength.. yet no data.
I flashed the 4.4.4 radio back on it.. same thing..
I've done the ##72786# reset..
So yeah.. I'm at a loss..
Anyone have any clue as to what might have happened?
Or anyway that I might resolve this issue?
