So I've got a US Cellular Note 4 running a SlimRemix rom. I flashed from a 9/1 build to a 9/13 build and when the phone booted up, wifi wouldn't turn on. It's grayed out.
This is what I've tried:
1. Flashed multiple different roms, other than SlimRemix
2. Restored from a previous nandroid backup
3. Flashed a stock build and lost root (have since re-rooted and I'm back on the 9/13 build of SlimRemix).
4. Tried Wifi Fixr and a couple of other apps in the Play Store with no luck
5. Did a factory reset within SlimRemix - This actually brought wifi back, but only for about half a day. I lost it again last night.
6. I've messed around with the wpa_supplicant.conf files a little bit (in various folders) but with no luck. I even tried renaming wpa_supplicant.conf to something else, so the phone would generate a new one on its own, but it didn't work.
I've seen this problem on various phones on various carriers, but I still can't find a direct solution to it. Anyone have any more ideas? I've only got so much data I can use this month...

So, my girlfriend's Razr M recently stopped connecting to wifi (any wifi that I've tried). I tried resetting the router, rebooting her phone, messing with all the settings on her phone, booting her phone into safe mode, and so on with no luck. Eventually, I just did a factory reset and it started working again. Things were okay...for a couple weeks. Now it's doing it again. She uses her phone for Candy Crush, Instagram, and text messages, so she isn't messing around with anything crazy, although I did root it the day she got it (basically just for ad blocking). She has all the same apps installed as before, so I'm hoping one of them is the culprit. Any ideas?

If not rooted then probably a hardware issue.
Try a restore with rsd. See my sigi
She's on a 4.2.2 rom.

It is a kernel issue or /persist then
So, I'm still searching for a solution. I've replaced the /persist and /etc/firmware/wlan/prima folders with "clean" copies (that have seemingly worked for others) with no luck. I've changed permissions, I've altered owners, I've done everything I can find that's worked for others. Nothing has fixed it. Like I said, I did manage to get it working again a few months ago by reflashing the ROM (I think this is what did it, not the factory reset) that was on her phone, but it eventually stopped again. I've even pulled the /prima folder from the ROM zip (there isn't a /persist in it) and replaced hers with it, to no avail. I recently RSD'd the latest firmware (4.4.2, iirc), but it didn't fix it (as has been noted on the forums).
Any ideas?
You could try erasing and flashing everything manually... Which I'm not sure of the commands I think there here in post #22 but I may be wrong... I'll look into something else
Edit... I googled it but running short on time so can't thoroughly search.. Does anyone know if
modem -> /dev/block/mmcblk0p1
modemst1 -> /dev/block/mmcblk0p17
modemst2 -> /dev/block/mmcblk0p18
Is related to wifi ?if it is does that get wiped and reflashed in rsd?

So for some reason my nexus 4 has lost all of it saved wifi locations. The weird thing is, is that it has happened before. I updated to 5.0.0, I started running into other issues then this happened as well. When I went to Cyanogen mod 11 it didn't show any locations available, but then when I went back and did a factory install of 5.0.1, the previously saved spots then showed up. Has anyone experienced anything like this and found a fix?
This is somewhat urgent because I am leaving the country for two weeks on Friday, and need a working phone. I am not sure what happened today, but my Sprint Galaxy S4 (SPHL720TBK) wouldn't connect to WIFI at my house. My tablet would, so I know it was a phone issue. I rebooted then was going through settings, and just checking things. The phone rebooted itself, and when it came back up, it went through a couple of screens, one of which asked about activation. It seemed like it was installing an update from Sprint, which it had been trying to do for a week or so. But it kept failing, saying it didn't have enough space for the download, despite there being several GB free internally and on the SD card. (I figured it must be because it was rooted). After a couple of additional screens on which I could only answer OK, the phone rebooted again, and that was it. It would not boot again. I decided to power off the phone and deal with it tonight. I can boot into recovery, and connect with Odin. I can boot to recovery and connect with ADB (in sideload mode). I know I could just do a factory reset, but unfortunately, I do not have a full backup since the end of January, and I would rather not lose everything. The phone was running v 4.4.2. I had rooted the phone several months ago with CF Auto Root using CF-Auto-Root-jfltespr-jfltespr-sphl720.tar.md5, so it was essentially stock, but rooted. Is there anything I can do to get the phone back on its feet that will not lose everything? Or anyway to copy data from the phone with it in this state? Any assistance will be VERY much appreciated! Thanks!
Fixed it myself

Since I didn't spark enough interest for anyone to offer advice, had to spend most of the afternoon/evening fixing these problems myself. Everything seems to be working, so I thought I would pass along key parts of this hard-learned lesson in case anyone else finds himself in such a situation.
First I booted into adb sideload mode, which is all I could do anyway. I installed philz_touch_6.23.9-jflte.zip and the aromafm.zip. I was then able to boot into a "normal" recovery mode. Aromafm was troublesome, and I eventually had to manually put the zip into place for it to work consistently. These are both WONDERFUL , and I highly recommend them both. Thanks very much to the creators! I used the file manager to find the files that I didn't want to lose, and used ADB to pull the files over to my PC. (ADB pull <source> <target>) Then I did a full wipe and factory reset. That did little other than delete all my data, which I had already copied anyway. The phone still would not boot past recovery.
I tried to use ADB to install a new ROM, but got a variety of errors. My phone being an L720T, there are not many ROM's available, at least not for which I could find functioning links. I finally found a TAR, L720TVPUBNG5_L720TSPTBNG5_L720TVPUBNG5_HOME.tar.md5, and used ODIN v3.09 to install that.
I still need to go back and re-root the phone, and install lots of APPS and restore data, but at least I have a functioning phone, and I can do the rest on my plane ride tomorrow.
I found the information I needed in a variety of posts here on xda developers, and would not have been able to get through this without all the helpful advice posted to other threads. So thanks to all of you for the wealth of information available here!
Hey everyone, let me start off that I love XDA and I have been using this site for years! So let me give you a little history. I am still on 4.4.4. Recently I finally updated it to 5.0 and retained root, sweet! I also had a custom lollipop recovery that allowed me to go back to 4.4.x. However, I needed the wireless tether function and I could not find a way to get it unlocked without flashing some mod (which would brick my phone) so I used ODIN to flash back to a rootable tar image that I have always used. It was 4.4.2 on NI2 Kernal. Now normally, no matter how many times I ODIN'ed it, flashed it, restore a backup, everything would be up and running in no time. However, lately my phone has not been able to connect to the network completely for some reason. I can make/receive calls and texts. Anything using data though would not work. I called Verizon to see if they could reset something from the back end and they saw me and connected and running. Needless to say, their help ended almost immediately. I am currently running Ricks ROM v19.2 G900VVRU1ANI2 and was only able to connect to data one time a couple of days ago. I had to restart though and when it booted back up, it lost the data again. It does show that I am connected to 4G LTE, strong signal. I have tried the stock ROM 4.4.2, fresh install of Ricks ROM, restore my backup of Ricks Rom (maybe two weeks old), tried Eclipse ROM, nothing seems to be working. I've never submitted anything on here asking for help so this is a first for me cause normally I can fix any problems I create, however, I cannot figure this out for the life of me. Does anyone have any suggestions that I can try? Thanks in advance!

I have a LG G2 Verizon Factory Unlocked VS980.... For service I have Straight Talk on a Verizon CDMA BYOD sim. It worked great stock. I never had a problem at all. 4G LTE all night and day, as soon as i put the sim in for the first time and turned it on the first time. Well i then used iroot, and AutoRec to flash TWRP. Stock it was on 24a 4.2.2. I like KitKat more then LP alot so I didnt really want to go to LP. I first Flashed a VS980 boot variant mod CM11 and it worked great. It kept my Data straight through the Flash. It held data for weeks no problem. Well at home I use WIFI and dont every try Data so one day I have no idea Data quit working until i went out, All mobile Data just quit working and i cant even use GPS, only calls and Text, no MMS either. I came home, searched up some APNs and edited it and it came back instantly. I thought that was pretty easy. Then I wanted to test the xdabbeb 2.3.0 because i liked the stock LG KK more then a CM Rom. Data again held through the Flash and for about the same time, 2 weeks, then suddenly one day i go out, goto pull up my broswer for internet and NO DATA. So I went home and couldnt edit a APN on this ROM, Every time i set it to the APN i found i hit SAVE and it just vanished, about 30 times i typed it in over and over. So I factory reset, didnt work, Flashed to 39A and tried LP Roms, Didnt work, Changed APNs on LP roms, Didnt work. Wiped it clean, flashed BACK to Stock 26a via KDZ, Didnt work. Changed APNs on stock, and wouldnt save again like before, It would save until i changed a certian field in the APN. So i went back to CM11 and set the APN, different APNs, Variations, still wouldnt work, So I went back to 28a Baseband, and flashed Xdabbebs KK rom again and again didnt work, but I loaded a Nandroid backup of that rom from the very first time i flashed it when it did work, and that brought my data back! So i sailed smooth on it for about about a week and BOOM, gone again!! I goto the Mobile Network settings and it shows 4G and 1X almost full signals, and LTE on the status bar still, when last time it didnt show LTE or the 4G's.
So, Im going to load this Nandroid again i suppose and see how it works, But what could be the problem? What is Changing settings wise or whatever and how? I am confused as hell on this! Can someone please help me out? I hate resetting my phone all the time, and dont want to make sure i have an OTG and my flash drive with me at all times and all my .apk's on my incase i need a weekly emergency Nandroid restore.
