MyTouch4G + MIUI = no more mobile data connection?...

I've searched the internets and can't seem to find any help with this problem...
This is the second time I've perm-rooted my HTC Glacier (had no problems the first time), and I decided to flash a custom rom to it for the first time...
MIUI, to be exact...love it, it works great...except for the part where it completely shuts off my data if I reboot it a second time or it turns off after I ...
When the phone starts back up again, MIUI will claim to have "updated" itself, and all that jazz...but when I look up in the title bar, there's no data signal whatsoever, as if the device allowing you to accept mobile data is completely shut off...it's just gone...I still have a phone signal tho, with some bars...the only way to fix this is for me to wipe the user data using the Custom Recovery thing, flash the Froyo factory reset, then re-install the custom rom...which is a pain in the anus...
I rolled back to Froyo before rooting, then perm-rooted and flashed the custom rom following the guides provided on unlockr.com, if that helps...I'm not even sure if it's a problem that's specific to the rom I have, but can anyone help me out with this?...

Re-download the ROM and verify the md5 if it's available. Reboot into recovery and format system (mounts and storage menu in clockworkmod). Then wipe data/factory reset. Then flash the ROM. If that doesn't work let us know.

Check your APN settings.

Wifi Not Working on Touchwiz

I am not sure what is going on here. If anyone could help out, it would be much appreciated.
I am on stock AT&T Touchwiz. I was running the stock kernel and ktoonsez's 5/27 TW kernel with no problem. When I flashed ktoonsez's 5/30 TW kernel, I lost the ability to connect to wifi (when I try to turn the wifi slider to "on," it switches right back off). I cannot for the life of me get it to turn on.
I tried flashing back to the 5/27 kernel and I still can't get wifi to turn on. I also tried odin-ing back to stock, which has the same problem.
The odd thing is that I can still use wifi tethering, so I know the wifi can work. I just can't get the wifi settings to enable wifi anymore.
Just for fun, I flashed the AOKP rom and ktoonsez's 5/30 AOKP kernel, and wifi will work in that rom. I just can't get it to work in Touchwiz.
Any thoughts?

Make sure your baseband and build are the same, ex. baseband MDL, Build MDL.
If these 2 are different wifi will not enable.

Baseband and build are both the same: 1337UCUAMDL.

before you flash do a system wipe so you have a clean slate, then flash rom and kernel and see if that helps, also you may try resetting to default settings from within the os.

I wiped system and then odin-ed to stock and it still didn't work. I am not sure how much "cleaner" I could get it.

Hmm well, it seems like you did everything right, thats really strange.

Yeah. I would understand that wifi was totally dead if if didn't work in the AOKP rom, but it does, so I'm stumped. I may just go over to the AOKP rom since I don't really need the Touchwiz features anyway.

after you odin back to stock did you do a factory reset from within the OS?
1. Open Settings.
2. Select Accounts.
3. Select Back up and reset.
4. Tap Factory data reset.

Odd... My baseband is MDB and build is MDL. I thought baseband had nothing to do with kernels..

It doesnt, i was telling him to look at those because i experienced something similar.
I flashed back to stock and my baseband and build were different, baseband was mdl and build was mdb and i couldnt turn on my wifi at all.

Oh ok... Maybe it was rom related and you probably needed a kernel to fix it (as it did for me).

I started having similar issues today with my WiFi.
Back story: I was playing around in ES Explorer trying to get WatchOn app to show in my app drawer and changed something that apparently shouldn't have and ended up sending my phone into boot loop. It also wouldn't recognize my SD card. After several faiked attempts due to my computer not recognizing my phone I was finally able to Odin to stock, re-root and restore from my Nandroid backup.
Which leads me to my problem. When I try to enable WiFi it just shuts back off and I get a security pop up saying, "Prevention Information - The device has detected an application attempting unpermitted actions and has stopped working. It is recommended that you reboot your device." And gives me an option to rabbit now or later.
After reading this thread I noticed that my baseband and build number were different and I will try doing a complete wipe and Odin to stock. Any other input would be greatly appreciated.
Thanks!

Maybe there is something wrong with the Kernel you are using. I don't know because I am on stock. However, the security message you are getting might be remedied by freezing "knox" and "SeAndoid". It probably wouldn't hurt for you to try it.

I'll try that first.
I should also note that I'm on stock room with clockwork recovery installed.

Just to update, I did a factory reset in CWM, reset davlik cache, factory reset from within setting and odin back to stock and wi-fi is working.
I'm about to re-root and not install the Nandroid backup and see if it's still working after that.

Final update.
I was able to get WiFi working again. Im not sure if doing this would help anyone else but this is what worked for me.
I did a wipe in CWM, cleared the cache and Odin back to stock. I then updated the software through the phone's setting menu. I tested WiFi before and after the update and it was working just fine.
Went ahead and rooted my phone again and WiFi was still working. Installed CWM again and tried the restore from my nan droid backup again and all is functioning normally.
On a side note, my 64GB SD card is working again also.

Wi-Fi won't turn on

Just got a brand new i9505 and the Wi-Fi won't turn on.
When I hit the Wi-Fi toggle it goes on for 1 sec then back off. I have tried a factory reset etc but just can't turn it on. I can't believe it's actually faulty. This is my 2nd faulty S4 out of the box. I brought a i9500 about a month ago and it keeps freezing & rebooting after a minute of use. Unfortunately I can't send that one back as it has a custom Rom & there is no way to reset the counter. I gave up on it and through it in the draw.
I decided to get a new one but went with the i9505 this time. How can I have so much bad luck. Is the S4 that unreliable?

I had the same problem with a custom rom wifi won't turn. All i did was change the kernel.
Hope this will solve your problem.

Instead of clicking the wifi toggle, why not try to go into settings and mobile networks
and turn it on there.
Good luck!

I,m using KERNEL][INT'L][AOSP/TW][6/10/2013B] KT-SGS4 - MDM - KTweaker

You can try booting into recovery and clearing the Cache and Dalvik Cache to fix the wifi. It's worked for me and other people on this forum.

i also have the same problem on my S4, basically the wifi wont turn on, i already did flashing firmware, wipe cache and dalvik cache but still the same thing

yeah same here. I've been researchin and flashin almost a month now and nobody seriously nobody could fix this issue. shame. i hate that it happened suddenly and without a warning.

Happened to me also...This is how I fixed it (accidentally of-course ):-
---First mistakenly dirty flashed stock ROM via odin v 10...That was an honest mistake
---Couldn't start my phone due to it...FC messages were appearing again and again...
---went to download mode...directly flashed CF-Auto Root and TWRP from ODIN again...
1) Wiped everything from TWRP
2) Went to download mode and flashed Stock ROM via Odin.
3) WiFi didn't turn on even in Stock ROM (came as a shock to me)
4) went to download mode...directly flashed CF-Auto Root and TWRP from ODIN again
5) Flashed "Doctors-Amputated-V3" and "CWM-Modem-I9500ZCUJOH2_2" via TWRP.
voila !! WiFi working again in the new ROM :laugh:

Hi mate,
Could you please explain what "Doctors-Amputated-V3" is? A custom ROM?
Basically, I have flashed the stock Samsung image and a previous backup, and still have issues having used PryFi. I'm trying to get my WiFi back to stock and probably flash a kernel or revert to whatever is most compatible, so as to stop my device rebooting...
Could you please recommend a kernel or modem to flash, and then the best kernel or modem to flash afterwards, in order for maximum compatibility. My S4 has always been stock rom, just with Root.
Appreciate your time Prateekgupta!
Cheers,

---Yes its a custom ROM...
---PryFi breaks phone's Wifi every time you use it...I've given up and uninstalled that app....Flash stock rom again through ODIN...
---The process I described didn't solve my problem...My wifi worked only for 20 minutes...After that it went back to grey...
---No software trick can help if your Wifi and Bluetooth both are not working...Its basically the Wifi antenna/IC that needs to be fixed...Its a hardware issue...

[Q] Voice and Data stopped working - Sprint

Not sure on this way. Running Stable 4.2.2 Google Edition and had 0 problems until a few hours ago. Went out after dinner, tried to google a phone #, but had no data. Rebooted (just for kicks), and still nothing and no voice. Trying to make a call I get "Mobile network not available". I tested using my daughters G3 and worked perfect so I know it's not that.
So, I would like to try 1 of 2 options, open to either.
1. Revert to the stock 4.2.2 and wait till the 4.3 comes around
2. Upgrade to test a newer ROM. I am reading up on the MF9 but a little unsure, if I am running an MD9, can I simply flash a newer MF9 ROM onto what I have?
I don't want to brick this phone, so what's the best way to move forward and hopefully fix this issue.
Thanks

Thanks. Looking here http://forum.xda-developers.com/showthread.php?t=2303917 there are plenty, but as I said, I am still on the MDL ROM, so I would assume pick an MDL touchwiz, no?
Actually I have a blu-Kuban (touchwiz) nandroid, I restored to that backup, and had the same issue. No voice, and the PRL, etc. all failed to update. I am downloading the stock deoxed MDL, and will try a wipe/clean install of him.
Tnx again

I'm actually running Blu Kuban as well and I do not have this issue. Try turning the cell data toggle off and back on. Also, make sure you aren't in airplane mode. I have noticed that sometimes the toggle is on while the airplane symbol will not show in the status bar.

Thanks, but since I did try a restore, that would ensure airplane mode was not the case as I don't use it nor would I have 2 ROM's both doing the same thing. I did do a wipe/restore with no luck, so now going to do a wipe/flash. If still nothing, will have to resort to going to stock and taking it to a local sprint shop!
Thanks

if restore fails.. try ##786# > reset on stock rom. you need your SPC/MSL for this.
if the 786 reset fails.. let me know in about device > status if your phone number is still listed.. and what PRL is shown.

Phone restarts at startup.

Well this is my 1st post so first of all hey everyone
I just spent a week in Amsterdam and my phone restarted twice, different times different days and I dont remember what I was doing with it back then.
But as I landed back home I put the phone back from "Airplane Mode" and went on to toggle "Cellular Data" on.
The second I pressed the cellular data shortcut on my the phone restarted itself but this time whenever it would finish the screen would be on but fully black and sometimes it'll show battery precentage at the top but then will restart again in an infinite loop.
Sometimes it'll pop up the "Optimizing Apps" window and will go through all 24, upon finishing it will restart once more and do the same.
I tried using the bootloader and it worked (the bootloader that is) but the phone would do the same thing even after Rebooting from there or shutting down from there and then turning back on.
I contacted tech support on chat but they couldnt help past telling me to go to bootloader and reboot, said I should factory wipe when it failed.
Also tried wiping cache but to no avail.
I have no backup of my phone (wanted to do one before the flight but got lazy and I suck for not doing one sooner) since probably October and google doesnt backup my contacts properly for some unknown reason.
I already downloaded Android Studio with everything included for me to try using adb to sideload stock without wiping but its my first time and I couldnt get it to do anything at all...
I already got the official stock .gz file from the motorola website.
Anyway here are the specs to my phone:
XT1575
Everything is stock. didn't root or change recovery once in my life.
Was fully updated and had plenty of drive space (I have almost 128GB with the 64GB version + 64GB SD)
I'm really lost here so help will be very appreciated.
Thanks in advance,
-Noam

Start with a full wipe and if that doesn't work flash the stock image. Not sure what your question is though as you never really say. Once fixed I would unlock and make a backup so you don't have to deal with this again.

The thing I pretty much want to know is if theres a way to either backup the phone now with it connected to the computer while in bootloader or recovery. or a way to flash the stock rom without wiping which I read someone did with his tablet. I cant post source normally because I'm a new user so here it is but change spaces to dots: schnouki net/posts/2014/08/13/flashing-a-stock-android-image-without-wiping-user-data/
Also while in recovery I noticed 2 options under wipe: 1. userdata only. 2. userdata+(insert something I dont remember here) and I was wondering what gets deleted in both? if I delete only userdata what data will remain? something helpful?

Sure you can try flashing without wiping data but being locked I personally wouldn't risk it. No idea about backing up in your state... somewhere I remember a thread on backing up without root try searching in q&a.

Out of curiosity why shouldnt I try flashing with no wipe if ill lose the data anyway? worst case wont I just have to wipe after it fails and flash again?
And I will try thank you
Do you have any knowledge about the 2 wipe options?
Thanks in advance

Well I tried turning the phone on and it took a couple of minutes before loading to a fresh start. It apparently wiped itself on its own. Managed to restore almost everything.
Anyhow the phone takes too long to boot now. Was even stuck at boot and I had to restart it.
Anyway to fix my software? Or at least check for corruption?
