Huawei Ascend 3g question - Android Software/Hacking General [Developers Only]

My 3g stopped working all of a sudden. All the apn settings havent changed, not deleted, nothing. I have my phone rooted but its been rooted for a week with no problems. I toggled apn on, the 3g was working, when I toggled it off an hour ago, it has never been able to turn back on. Any idea what I can do?

Suddenly stuck in airplane mode with an unflashed rom

Hi Guys
I have been using my Streak for ages now, and aside from rooting it I have not hacked it at all.
Yesterday I was trying to work out which app is draining my data so I installed a number of data loggers and droidwall (android firewall).
Aside from discovering that the ROM does not support logging data per-app, everything was fine. But this morning I had a phone call and after I hung up it rebooted and started in airplane mode and since then I have not been able to switch it back.
My SIM works in other phones, other SIMs dont work in this phone.
I tired rolling droidwall back: re-enabling all apps network access, disabling the firewall and uninstalling but that didn't change anything, I have also messaged the author but since it happened hours after I last made any changes I don't 100% believe it is at fault?
I can get wifi, but not gsm.
I have almost finished pimping it out I really don't want to flash the rom Do I have any other options?

[Q] Data stopped working out of the blue...

I'm running the latest RG2x MIUI ROM. One morning I woke up to a dead G2x. Charged my phone up, turned the power on, and no data from T-Mobile.
Phone Calls/Texting and WiFi works perfectly fine.
It's just my 3G/4G not working.
What should I do from here? I haven't tried flashing a new ROM on it yet.
did you turn data off? if u did b sure to turn it back on.... if not then i would try resetting your apns. not really sure on how to do this, because iv never ran miui before. i figure ud hav to go into your apn list then hit menu and hit reset apns

[Q] OpenSensation ROM: Shutdown when data roaming enabled?

Running OpenSensation ROM 20120621 (CM9) and Bricked kernel 3.0.36 and experienced a weird problem yesterday while roaming. The device shut down itself several times.
What happend:
I have a german SIM card (Vodafone) and went on a shopping trip to France. As I have a 100 MB data roaming option on my contract, I wanted to try this out. So I enabled data roaming in the system settings and waited.
Nothing happend. I opened browser and got no connect. I went back to settings and enabled "national data roaming" too. Now I finally got a data connection and was happy and went back to shopping.
10 minutes later I looked at the Sensation again and saw that it was powered off. I booted it and opened browser and after a couple of seconds the device went off again. No error message, nothing. I tried this some times more, same result. So I disabled data roaming again.
In the evening back in my own country without roaming I was very astonished to see that the device still shut itself down when doing some data transfer. I went to settings and saw that I still had "national data roaming" enabled. I disabled it and finally everything was normal again.
Did anyone experience the same? What's wrong?

Nexus 5 WiFi Crashing Phone

Hi all. I have a weird issue that after Googling it doesn't seem anyone else has had.
The issue started earlier today, in the morning. I was using my phone on the WiFi and it was working phone, then my phone crashed, restarted itself.
I noticed it wasn't connected to the WiFi, went to the WiFi settings and where it usually says the list of networks it said "Turning on WiFi" and the slider at the top was greyed out so I couldn't turn it off.
I tried airplane mode and that didn't help. But the phone was working fine on my mobile data so restarted.
Now the weirder part starts. I basically have an issue where, if I turn on the WiFi, my phone crashes, or doesn't act like it's turning the WiFi on.
Even going Settings and then pressing on the WiFi option freezes the phone.
The problem started when I was still using 4.4.4 however since the problem developed I've used my mobile data to download the updates and now have 5.1.1 I think.
The problem persists even after updating to the most recent version and doing a factory restore. The phone is currently completely stock with nothing downloaded on to it. All I did is go through the first time setup for the device.
The WiFi currently is off, and the phone is working however it won't connect to my data, it has the signal bars and then an ! instead of a 4G icon.
If I try to turn the WiFi on it crashes the phone.
The phone is still under warranty so I plan on contacting LG on Monday however it's currently 3:34 AM on a Sunday so I have a day until I can call them and was hoping for a solution in that time.
Thanks in advance. I have the phone to hand so anything you want me to test I'm able to.
There is some information I didn't type as I don't know what is important was trying to avoid a wall of text so if you have any more questions I'll answer I best I can.
Thanks for reading, I hope you can help!

Mobile data disappeared

As of yesterday, my mobile data has stopped working. I can still make calls, and according to Net Analyzer the network type was LTE.
I flashed to 930U from 930VL a few weeks ago, but mobile data seemed to have been working fine in the interim. Any idea what could be causing this?
I do have mobile data on and did try toggling it, I have tried rebooting the phone, and I cannot edit my APN settings, but it's using "Tracfone - Verizon / VZWINTERNET".
Any ideas/similar problems/solutions are appreciated!
You haven't got anything like battery / network data saver turned on?
Changed anything in the developer settings?
Got another phone you can put the SIM in and make sure it's not a SIM issue?

Data saver is off, and I don't think I've changed anything in the developer settings.
I'll have to borrow someone's phone to check the SIM. What does it mean if it does or doesn't have mobile data in theirs?
If it works in theirs then you know it's probably your phone, if it doesn't work in theirs then you know your phone is probably okay (assuming their phone isn't carrier locked).
Surprising (& confusing) updates
Service in my area got a little loopy today during a large storm. We lost power, and so WiFi, at which point I looked at my phone and it had working 3G. Later, it showed LTE, but no mobile data. Then working 3G again, which I took a screenshot of. Since then I've had LTE & EVDO-A, both non-functional. What the heck is going on here?
Now back to working EVDO-A 3G, for some reason...

Edit: 3G is working reliably, and LTE is down.
