What I just did (and keep in mind I have no idea if it will be of any help to you) is I reverted my recovery to the stock image, and forced a hard factory reset. Originally I was having issues with data connectivity and speeds, and so far (after doing all the above) it seems to have worked. My last resort, assuming the above was unsuccessful, was to go to a local Verizon Retailer and buy a new SIM (though I have two on hand at the moment, so that would be a last last LAST resort).
Alternatively, what ROM are you currently on? I know that when I flashed a GPE ROM and began fiddling with the phone's network settings, I lost all data connectivity. Perhaps try what @spy4ka suggested in a thread I opened a while back?

As I understand, you have the Google edition. I had the same problem. It is an easy fix:
1 go to phone app and dial *#*#4636#*#*
2 click on phone information
3 under preferred network type select LTE/GSM/CDMA auto
4 wait for signal bars to show up and you're done.
Hope it helped.

Finally, you could attempt to restore from someone else's Nandroid/backup, if all the above fails. Here is a thread with links to a Nandroid created by @krazie1, though you will have to ask his permission to gain access to them.

Hey, I could help you. There are 2 main reasons you don't get data: 1 it is a software problem( which is fixable) and 2 it is a hardware problem( which is not).
First you would change these in your phone: ROM, kernel and modem( I don't think they do modems now ). We will focus on ROM and kernels.
The very first thing that you should do in backup your data. Trust me it will help a lot ( I have some really nasty stories about how I flashed the wrong thing and I soft bricked my phone).
Next you should install a stock ROM. ACR is good and lightweight ( plus it flashes a kernel for you, so yay). You can find it here http://forum.xda-developers.com/showthread.php?t=2716597
Now flash this thing.
If you still are not getting your data try flashing the stock kernel. You could find to here http://forum.xda-developers.com/showthread.php?t=2712793
If none of these work, you have a hardware problem and return it.
Hope it helps.

I would first follow @spy4ka's recommendations, especially flashing the stock Sense 6 ROM's kernel. If that still doesn't help, I actually would suggest getting a new SIM card instead of a full factory reset... for now. Since you have access to 3G data, you have at least solved part of your data connection problem, and to me seems like it may just now be a faulty SIM (such as failing to activate/is now a complete dud). After all that, if you still have issues with data, I can coach you through reverting your recovery back to the stock image and performing a factory reset (you will lose all data on your internal memory, along with root, which is why this shouldn't be done unless all the above fails). If that still doesn't work, then your final option would be as @spy4ka suggested, returning you current device and getting a replacement. If you are still within Verizon's 14 day trial period, then this will be a free replacement. Otherwise, it will have to be through your phone's insurance, and will likely cost $99.

[Q]How can I go back to ICS from JB?

My wife recently updated her phone via wifi to JB from ICS and her phone is damn near unusable. She wants to throw it out on the freeway. Her phone since the update is sluggish, and a constant headache for her. Her phone is stock, and unrooted. Do I need to root it in order to go back to ICS? Sorry in advance if this has been asked before.

You could flash in an ICS factory image using the built-in recovery (or at least I seem to remember doing something like it). But before anything, you need to know which variant of the phone you're dealing with (i9020a/i9020t/i9023/etc.) Just turn off the phone and check below the battery for the exact model. Once you have that, I (or somebody else around here) can link you to the right image for the device. :laugh:

Oh, there seem to be no full recovery-flashable images for the NS4G. You could install a full image using fastboot but that would require unlocking your phone's bootloader (which more or less voids any warranty) and would also wipe all the data. If you're not particularly attached to all the data in the phone, you could try a factory reset to see if JB problems get resolved. Otherwise, maybe some other forum member might have a better idea.
OK, thank you. I'm about to go to sleep, and I'll ask her in the morning how she feels about the phone being wiped. In the meantime, maybe others can shed some info also. Again, thanks for the replies.
My wife and I both have the NS4g from Sprint, but our approach as to how we use the device is very different. She doesn't like change, simply wants the parts of the system that she uses, to work ... mainly tethering, mms, camera, phone. If your wife is anything like mine ... make your life a little easier, and just root the phone. It will give you so much more flexibility and choices. About a week ago, OMJ posted a stock, rooted rom in the NS4g development thread that would be perfect for her. It's all there ... smooth ... quick ... everything works.
i think before trying anything that could avoid your warranty you should do a factory reset ... it probably could solve all your wife issues ... it will just delete all your app but not photo or documents ( unless you select that option ) and you could after reinstall just the really needed apps your wife need ...
@wmdunn - She mainly uses her camera as well.
@kriout - doing a factory reset will still give her back JB tho wouldn't it? I'll ask her just to try it, and if it still runs slow, I guess root it?

The camera software in JB is really nice. As for rooting ... I have rooted every phone we've owned, and never had any problem with warranty issues. The rooted versions of the stock JB rom are smoother and quicker than the ota.

Constant Switching from 4g/3g/edge

So I have used TMOUS rom for ALONG time and recently decided to switch to use Cyanogen being a fan of it form other platforms.
While on the TMOUS rom I had 4g connectivity in my area about 90% of the time with the occasional drop into 3g here and there. It always displayed a 4g image in the top.
When I switched to Cyanogen that pretty much stoped. It always says 3g and is slow as hell. every once in awhile it will say H+ but not for long. MOST of the time it is constantly switching between 3g/4g/edge then shutting off.
Now im not sure if its a rom problem or not, but its making me want to switch back to a TMOUS rom.
Any suggestions would be great!
Edit: Just for clairification, I am S-On
I have this problem as well. I even ran the ruu back to stock and it is still happening. Please and thank you!

I have been trolling the net for weeks but have not found a solution yet.
I've posted in threads here but no solution.....
My issues started when I went to CM ROM - I used to have great 4g all the time before I went to custom rom (I was on stock TMO US) .. Now no matter what I do, I am not able to get 4G again.... it's really irritating...
I've tried a bunch of custom ROMS.. I am on 1.13 HBOOT and S-ON .. .. CID = HTC__001 (originally my CID was stock TMO US CID whatever that is but now its not that.. I don't wan to run RUU because I don't have TMO US CID and dont want to brick my phone)
You can set your CID back easily with the All in One ToolKit found here.http://www.hasoon2000.info/getdownload.php?file=One%20S/One_S_All-In-One_Kit_v4.0.rar
That is not the problem, unfortunately. It just doesn't make much sense, whatever the problem is; and especially considering after a full RUU restock. That has always fixed whatever mess I have created in the past.
This rom should fix your problem. Dont forget to clear storage from bootloader. It will erase everything thoug. And follow the steps under show contents link.

I not sure if its a CID problem. The only thing I ever did was upgrade to the newest Hboot and load in the CM rom. even going back to the TMOUS rom does not fix the problem.
Its so bad, and never on 4g that im considering getting a new phone.

I'm in the same boat, friend. I've tried literally everything suggested, I'm just wondering what exactly happened in the flashing of the Maximus rom. The worst part being is that I GET 3g/H and then it drops back to E. It's so strange. The only thing I've not done is contact Tmobile about it, and i highly doubt that they would throttle my bandwidth without contacting me in some form or fashion.

my phone is still under warrenty. Im wondering if i am able to revert back to stock without them knowing if I can get a phone replacement.
From what I've read, it's doable; even with an unlocked phone. But I'd really like to know what in the dev's source code made this happen... it's a bit ridiculous.

I just wanted to say, that I did this and it worked!
I did this the first time, but i just flashed the rom with a full wipe.
This time what I did was go into TWRP and erased everything....and I mean everything except TWRP.
After that i flashed the rom and boot.img and everything works great. 4g all the time again!
Sucks that im back on an older version of jellybean, but oh well

So what I did first was go into TWRP and selected wipe. Inside wipe i selected EVERYTHING, every little box. Then Wiped it.
This left nothing on the phone but the recovery. I then loaded on SuperSU from TWRP. I download the stock TMOUS rom that was posted earlier in this post.
In TWRP I mounted it and hooked it to computer and transfered the rom over.
Once the rom was on I did the install of the rom.
I rebooted the rom into bootloader.
Once in bootloader i put it into fastboot.
I had previous extracted the boot.img from the rom.
I sent the boot.img over via fastboot which restarted the phone.
Once it got all started up. No issues. I am on 4g 99% of the time now.
Im thinking the issue was definatly based in the CM rom.
Since this worked I wanted to test things out since my phone was pretty much stripped of everything.
I tried out Viper rom and a couple of other non CM based roms, and I have had no issues.
IM back on teh TMOUS rom though. Wifi calling will win over when i go overseas.
Thanks, but it did not work for me. It is a hardware issue on mine. Thanks again

Must be.
I did find something out though doing all my research. Did you ever at any point update the radio? TMobile uses some frequencies that some companies dont use.
It is my understanding that some of these roms are packed with radios that are generic and thus ment for multi carriers.
Not sure if thats your issue, but might want to look into.
Its nice being back on 4g though.

Bought used N5- No mobile network whatsoever!

So i bought me a new used nexus 5 on craigslist from some old chinese guy. He said it wasn't connecting to a network no matter what or whose sim cards he used and how many times he rooted it. the phone is on stock unrooted 4.4.2. I got it on the cheap and was hoping ot fix it up and use it. Any idea what might be wrong with it?

You don't mention that YOU returned it to stock, you just said it was stock and unrooted. If it is exactly the way he gave it to you I would fastboot flash the stock 4.4.2 images from google and see what that does for you. You could simply have a corrupted file somewhere.

Yes when he sold it to me it was stock. I haven't returned it to stock, ive rooted it and tried diff rom/basebad combos and still nothing. Theres also a weird persistent notification that i cant swipe away that says Nework (ROGERS) Unvailable....even when i reset and try a Telus sim!

This being a Nexus you have little or no risk of doing damage by playing around. My original Droid X was always threatening to self destruct if you messed up the tiniest little step. Spending a couple hours learning about and installing Fastboot and ADB will be the best investment you can make. Once you learn to use them the fear of messing something up is gone. You can flash roms at will without worry as you can always return to stock and start over.

Oh thats perfect bro thanks, nice and straightforward. Will see how this goes after school. I just htought it was maybe a radio issue or rom issue so i thought i could flash around and fix it.

Oh really?how does that happen!? The imei isn't blacklisted or anything and shows up as a registered imei. I tried flashing stock image and still no dice! Looks like I'm doomed. Any other suggestions?
That usually happens when the following steps occur.
The original owner unlocked bootloader.
They put twrp on it and did a full backup including ESN
The device developed a fault so they RMA'd it.
They restored the backup from the faulty device into the new one.
The ESN is device specific and by restoring it onto a different device you end up with not being able to connect to a network.
You can check by going into the about phone menu in the settings. If it displays your imei then I don't think this is your problem.
Have you tried popping the back cover off and checking the antennae contacts

[Q] Wifi Error - Can't turn on Wifi

I had problems (even before rooting) where my wifi would simply not work. If I go into settings and try to switch it from On to Off, it would simply say there was an "Error". Earlier in 2013, I had rooted and installed a Cyanogenmod Rom on my phone (I forget which one exactly, but it was JB). After a while, I went back to stock. A week or so later, the problem happened again. I did a factory reset. It fixed the problem for a day. Then it happened again and not even a factory reset would fix it.
I got a Nexus 5 for Christmas, so I'm looking to sell this phone but want to fix the wifi before I do so. I've seen a couple of people with a similar problem but no fixes. Does anyone know what is the cause of this problem and how to fix it?
Thanks.
Um, how did you return to stock? Ruu or a backup?
Sent from my One Xl using xda premium
If it was happening while your phone was completely stock I don't think there's anything you can do that's going to be worth it. It'll likely have to go to a repair centre and the cost would be more than you can sell the phone for. You could list the phone on Swappa, there may be people who require only the display, motherboard etc.
You could try running an RUU as a last attempt saving though.

A nandroid is only going to put you back on the stock ROM, not stock recovery, etc. You may also have s-off, unlocked bootloader, SuperCID, etc. that would make the phone "not stock", but you have given zero details for us to answer your question.
Going back to stock should only be necessary for selling the device or returning for warranty (not necessary for AT&T).
Well, a nandroid, as stated by Tim, only gibes you the stock ROM. An ruu wipes anything that might have messed with anything.

I used an RUU to go back to stock.

If there is any other information that would be helpful, let me know and I can try to provide it. I'm planning on selling it on Swappa...my hope was to fix the wifi before doing so.
If you've done an RUU and still no WiFi then you've run out of options.

[Q] 4G/LTE band missing

I was experimenting my M8 with T-Mobile sim card. I flashed 5.0.1 GPE ROM and everything worked fine. I also changed its CID to T-MOB010 and flashed ViperOneM8 3.2.1. It worked fine as well. But after I reverted everything back (by loading 3.28.605.4 0P6BIMG and firmware, and restoring a TWRP backup), I discovered I can no longer get 4G/LTE signal. I can only get 3G. I tried flashing to RUU M8_VZW 4.4.3 (firmware &0P6BIMG). But it doesn't help. I dialed *#*#4636#*#* but didn't see any option/menu. When I use 4G Switcher app to select band, 1900MHz band isn't available. The network type is set to "CDMA/EvDo/GSM/WCDMA/LTE auto". I am using CleanROM 3.0. Any advise will be greatly appreciated.

I was experimenting my M8 with T-Mobile sim card. I flashed 5.0.1 GPE ROM and everything worked fine. I also changed its CID to T-MOB010 and flashed ViperOneM8 3.2.1. It worked fine as well. But after I reverted everything back (by loading 3.28.605.4 0P6BIMG and firmware, and restoring a TWRP backup), I discovered I can no longer get 4G/LTE signal. I can only get 3G. I tried flashing to RUU M8_VZW 4.4.3 (firmware &0P6BIMG). But it doesn't help. I dialed *#*#4636#*#* but didn't see any option/menu. When I use 4G Switcher app to select band, 1900MHz band isn't available. The network type is set to "CDMA/EvDo/GSM/WCDMA/LTE auto". I am using CleanROM 3.0. Any advise will be greatly appreciated.

Try a factory reset using stock recovery. Not twrp or any custom recovery. Has to be stock recovery.

I understand completely where you are coming from. I flashed the same rom and my phone stop connecting to LTE when in global mode. I have flashed the 4.4.2, 4.4.3, and 4.4.4 RUU and went into the stock recovery and did a factory reset and it still does not work.
Right now I am running cleanrom 3.0 also. The only time I can get LTE is when I go into settings and switch it to LTE only.
The only thing I think it can be is when I do the factory reset on the RUU, the says restoring Verizon NV flash rather than formatting it. I want to try and flash a T-MOBILE RUU to see if it will format it and clear it out then switch back to Verizon but I don't know if that will brick my phone. If I can't find a way to wipe the NV the only thing else to do is run the phone over with my car a couple times then claim warranty.
Not trying to knock digital high's rom because he and several others put a lot of work into the stock 5.0 rom and I really appreciate the effort, but I wish I didn't flash it because I think there is an underlying issue with the rom that is affecting a small portion of our phones. And it is so small that there is no support to fix it. I have scoured the forum to find a fix and nothing has worked so far. But these are the problems we accept when we hack our phones and flash non factory software.
I hope you find a fix and if you do please let me know. Good luck.

Factory reset using stock recovery does the trick. 4G/LTE is back. Thanks a lot for the suggestion. Much appreciate it.

I'm having the LTE issue as well. I'm currently running DigtalHigh's GPE 12/18 release with the updated firmware. LTE works on first boot until I connect to my Wi-Fi network, after that I never see LTE again. I tried everything, and I mean everything. I tried the RUU back to 4.4.4 and doing a factory reset from that... I get the same result, LTE on 1st boot until the WiFi connects and then it's gone for good again until the next complete reset.
The most recent thing I tried was replacing the SIM card (while on the GPE rom)... this worked flawlessly. I had LTE again for a few days... until I made a phone call from my car using Bluetooth, at which point the phone geeked out, switching from speaker to line-out to bluetooth audio and eventually dropping my call (not sure if that is somehow related to the LTE issue), but now I'm back to no LTE again.
But I get full bars of 3G, so I've got that going for me... which is nice.
Is it possible for you to put in a new SIM while on another Rom like clean rom to see if LTE will stay?

DH GPE with custom firmware has hooped the VZW LTE radio settings, it has overwritten them...no amount of custom rom re-installations will fix this.
As stated above, the easiest way to fix this is to simply flash a stock Verizon RUU, and THEN do a factory reset from the stock recovery. I used http://forum.xda-developers.com/ver...ent/ruu-m8vzw-4-4-4-s-off-onlynewest-t2914914 with the SD card method and it worked fine.
After you do the stock factory reset you can then install DH GPE again, without using custom firmware.

I tried installing the stock ruu and using the stock recovery to fix it. It hasn't worked. Did you use the method of installing through the phone or the computer?

I put 0P6BIMG.zip in ext SD card and booted from HBOOT.
My LTE just automagically kicked back on after I reset it three weeks. Glad it doesn't have to meet the tire of my car. I pray it stays on

I posed this question on another thread, but I'm trying to understand what you mean when you say "stock recovery". I know what it is, but what I don't know is what stock are you referring to; do I have to downgrade to 4.4.4 or when you mean stock it doesn't matter if it's Lollipop 5.0.1.? Thank you sir!

I mean the matching HTC provided recovery img for the firmware version you are on.

Boy this horse is getting beat to death. Go to Dottat's RUU posts where he explains it all. I used the 5.0.1 S-Off one. Once it's installed, boot, and then reboot to it's stock/factory recovery and do a factory reset. That will fix your 4G/LTE problem. Then you get root back and flash a "custom" recovery like TWRP. I followed the Sunshine instructions. If you don't want/need root or TWRP skip it and you'll have an S-off stock not rooted phone.

It's been a few years since I wore my horse, the HD2 to death and I didn't stumble on to the cure until the wee hours this morning. It eventually comes back and like the wife hitting your head with the iron skillet...ding, ding, ding....external micros SD card and RUU; I remember how to do that. I'm S-Off, this will work. What I didn't know is what is "stock"; factory state you walked out the store with or matching the ROM to the firmware and if I'm going to downgrade to reset the NV configuration, what all that entails. It's the jargon, I need to learn and that takes time. I sincerely appreciate what the OPs do and where they direct me to; thanks!

Answered this once already in the last 24 hours and this will be the last time.
Stock recovery is the matching HTC provided recovery img that is from the matching firmware version you are currently on. If you are on 1.X firmware it's best to find stock recovery from the 1.X ruu or firmware zip file.
Stock recovery is only provided by HTC.
Why is this so dang difficult to understand folks and why does the question need to be repeatedly posed?

Well, not all brains are wired the same. I do understand providing a direct link again or now would be like defeating the purpose. Although sometimes some words in some directions or answers are misleading to One and very confusing.

Point is the information is already out there. Nothing misleading about it.
There are some basic premises that better be understood first lest he avoid failure by leaving that boot loader locked and s on.
Capiche?

Because, those of us doing the asking while we truly and sincerely appreciate the work all of you do, and believe me "I" do, some of you, not all of you completely fail at the teaching aspect of the knowledge you possess. That said, thank you very much; it worked. I can't tell you whether it was the factory reset or performing the edit inside ##778; the moment I put the wife's Straight Talk (Verizon) SIM card in; 4G LTE returned. I did not have access to the dial code until now. Again, thank you!
