[Q] No Mobile Data/GPS, Tried Every Solution Possible - Galaxy S II Q&A, Help & Troubleshooting

When I flash my new custom rom, I still didn't notice that I can't use my mobile data. When I get RR as my permanent rom, when I checked the mobile data, it's not working anymore. I tried flashing every rom, but it's not really working. I tried all solutions, APN, factory reset, efs everything! But it's not working. I reverted back to the stock rom, and it's working. Flash a new rom and it will no longer work. What do you think is the problem?

[Q] WiFi suddenly stopped working

I've tried it all folks. New kernels, factory reset, different radios, different ROMs. Every-thing. The WiFi will turn on for a quick second and I will get an error message "Unable to scan for networks" and then the Wifi will just turn on and off on and off over and over again. I've even deleted the files in the data/dhcp and data/wifi folders. Rebooted, still same issue. I've deleted the files and flashed a kernel and rebooted, still same issue.
Of course I am still in contract and will have to purchase a new phone outright from Verizon if I can't get this issue resolved......
I don't know what else to do here.....
Did you try formatting data and system before installing a new rom from recovery? If that doesn't work i would say its a hardware issue. You're not restoring system data with any backup programs are you?

I've wiped pretty much everything known to man on the phone. The ROM installs are all "fresh" I haven't tried to install any APPS on the phone. Just wipe everything, factory reset / Dalvik Cache, all of it... install fresh ROM. Try to turn on Wifi, phone boot loops. No matter what ROM I install, still same issue with Wifi / boot looping.
Well guess we can close this out. I went out and paid full boat for a Samsung Nexus since I couldn't fix this issue.
I'd like to reopen this topic. I had been running Bamf Forever 1.10, but last night I decided to try another ROM because it's been running really slow for some reason.
Did a wipe (factory reset, Dalvik cache) and installed Thunderstick. Now WiFi is broken -- the exact same problem as described in the original post. I tried flashing a new kernel and new radios, and cannot get WiFi to work.
Does anyone have any suggestions? Will flashing back to stock ROM/unrooting help?
Thanks!
@ajoesq I had the same problem when i installed thunderstick thru boot manager. My wifi stopped and I could get it going on my phone rom. So i booted back into thunderstick and wifi was working. Booted back to hte phone rom then into recovery and then i flashed my phone rom again without wiping or anything (Thunbershed V1.2) and it worked fine. wifi started agian.

Run a logcat when you try to turn wifi on. Put the output on pastebin.com and post the link. This might tell us what the problem is.
I'd make sure that the radio(s) were at least at the minimum of what the ROM called for.

[Q] Messaging Has Unfortunately Stopped?

Sup,
So, I flashed mutliple custom ROM's when I got this device like any other crack-flasher would but I then realised I much prefer it to be running stock with root access until an AOSP ROM comes along.
So I came from Omega 4.0 to stock LE8 in the UK, ever since I've flashed this stock ROM (Which is odexed) I keep getting the message "Sorry, messaging has unfortunately stopped" every time I open the app. I've tried wiping data/cache/dalvik and flashing in Odin again, same issues. I then went back to another custom ROM (HyperGalaxy) then went back to stock to test, still the same.
I have also tested an inverted AOSP 4.0.4 Mms app which worked on Omega, but didn't work on stock (Got the same message)
Data of the Messaging app has been wiped, i've disabled the app, rebooted, enabled again, still the same issues.
I've searched and I found 2 other threads with the same thing, but noone has been helpful enough yet.
It seems like the phone still thinks its running a Deodexed ROM but I need to get it back to full working order since I need to text something.
Any help is appreciated.
Try a factory reset...

Probably didn't make it clear enough, I did that already. 3 times to be exact.
i have the same issue. Need help.
i get this message with multiple apps.
all of them are standard run of the mill things like browser, messages, video player. My phone is only a week old and completely stock
some real bugs in this phone still that need sorting asap. poor effort by samsung really
Same issue here, has anyone found a fix for it yet?
I only encounter this in hyper x rom. So far so good in omega
Ok,I had this issue when I tried to install different firmware and modems using Mobile Odin. It fully resolved when I flashed back the official UK firmware and modem (le8) using normal desktop Odin. No force closes whatsoever since. Incidently, I'm now using LE9 firmware with UK CSC, rooted, with no issues at all. I used chainfires recovery, then flashed superuser to root.
Hope this helps.

i got this everytime i clear cache and or wipe data from recovery before flashing new fw's.
so never wipe anything before flashing. if u already wiped, then flash it all over again and it will be all ok

Mobile Data not working on AOSP Roms

Hello there,
I'm having some frustration issues lately with any AOSP ROM
I recently began to notice that mobile data refused to work (it only worked once on the first setup where you choose your language, etc.), after flashing a new kitkat rom. I also noticed that my phone could not hold a stable wifi connection with any router.
No amount of rebooting or turning airplane mode on/off would do anything, so I decided to flash my previous ROM that I was using earlier with no issues, and to my surprise, found it was also having this issue.
Thinking it was a hardware issue, I reverted back to stock using an RUU, and everything worked perfectly. Mobile data, wifi, everything.
I tried flashing an AOSP Rom after unlocking for a second time, and just like previously mobile data didn't work, but after flashing any stock based rom like Venom ROM, it does. Any suggestions?
TL;DR: My Droid DNA's mobile data and wifi suddenly only works on stock-based roms, even after a running an RUU
The ROM I updated to was: Omnirom 4.4.1
The ROM I had previously was: Carbon Rom 4.3.1
The ROMs with working data: Venom, stock, and everything else based off of stock.
Thanks in advance :good:

I would suggest you to flash a radio. If that doesn't work back up any data and flash any stock based rom including stock recovery. Once it is flashed let it boot and then factory restore in bootloader this will repair any radio partition.

My mobile data doesn't work after updating to Cyanogenmod Rom

I am using a Sprint Galaxy Note 3. After enabling mobile data it does not connect to the internet. How can I fix this?
Unfortunaly every phone is different. I have the same problem. Try reinstalling the stock rom again. (Oc5) after you are done flashing and setting the rom up. Reflash your new rom. Always make sure you back up your original rom. As mentioned before, every phone is different. While many have no problems others can not say the same.

No Cellular on Custom ROM

I had my s2 hard bricked and now i got a new motherboard for it, the thing is that on all stock roms (2.3 and 4.1.2) the phone works perfectly but all the custom roms 4.4 5.0 6.0 the cellular does not work, it gives me no service, tried flashing modem from cwm but no change.
i also tried different recoveries etc but custom rom no service
sometimes in custom rom imei used to be blank but it comes back after reboot, in stock no issues at all
any idea what im doing wrong or is there something up with the new board?
thanks,
Update
I was searching and I read somewhere that installing NeatROM by Sale will help, i downloaded and installed it, the good news is that cellular works and i have full 3G access.
Question: How to proceed further?
i could experiment but the thing is that if i flash a non-working rom (no cellular), i will have to flash stock from odin and start all over again
any ideas?
Update 2
i tried NeatROM and it worked perfectly, then i tried installing slimLP and boom, no service again, this time,my IMEI was blank too, so now i'm flashing stockrom again.
any idea anyone please?
