[Q] Suddenly lost 3G on my Arc S (solved)

Yesterday I flashed CM 7.2.0 FXP109 on my Xperia Arc S.
3G worked perfectly.
Later I installed AdFree, and set my phone on the table. I do not remember if I rebooted it first. About an hour later when I picked up the phone again, I had no 3G signal. Still nothing today. Tried re-flashing CM7.2 FXP109, whilst first wiping data/cache/dalvik. Still nothing.
Tried to put it into airplane mode, waiting 10 seconds and turning it back off, checked all the settings (and the APN settings are set the way they should).
Also, after having wiped the phone data and cache and re-flashing, somehow USB Debugging and Unknown Sources are still turned on. Shouldn't that reset?
Either way, something is wrong and I'm at a loss. I have no idea what to do, and I just bought the phone yesterday. Before that I had an X8 with GingerDX, so it's not my first time installing a bootloader, and I haven't had these problems on my old phone.
Any help would be greatly appreciated!
EDIT:
I found a (possible) solution, at least it seemed to have worked for me.
I flashed a different kernel (and thus got a different version of CWM), formatted, wiped cache/dalvik cache and flashed back to the kernel needed for FXP109. Then I installed FXP109 CM7.2 and GAPPS again. Problem solved.
My guess is that for some reason, I had to flash to a different kernel and back to solve it.
Cheers!

[Q] Stuck on bootloader after changing screen density with Rom Toolbox

Hey guys. As the title suggests, I can't boot my Note 2 (sgh-i317). It is stuck on the AT&T logo and while it's stuck there it vibrates slightly every 5-6 seconds. I tried changing my screen density to 240 and it worked for a bit but annoed me. then I went to change it back and got this problem. I accidentally set it to 360 I think though, instead of 320. I have wiped the cache. I have wiped the data. I have installed roms countless times already with Odin. I'd imagine my reset counter is at over 10 just from today.
I've been searching on google and these forums for hours and have seen many suggestions, but none of them have worked. The farthest I have gotten was to get the phone to boot, but once I start going through all the setup stuff I begin getting error popups saying that Touchwiz home has stopped responding. As soon as I push OK the error immediately pops up again. I seriously can not do anything with my phone.
Is there any way to get a stock build.prop file somewhere for this phone, and if so, how would I install it if I can't even boot into the device?
Any help would greatly be appreciated. I have no idea where else to turn here. Thanks!

Do you have a backup to restore from recovery ??
If not....then power down the device and remove the SD card and place it into a PC card adapter...
Then download or copy over a suitable rom...
Then place the SD into the phone and boot into recovery...
Fully wipe the device and flash the rom of choice...
Reboot....set....profit....g
Edit:
Are you certain that your power button is not stuck ?
If the method I suggested fails... and rebooting occurs with vibration...then your power button is suspect....g

Thanks. Well I got it to boot finally, however there's been a couple issues since. It's on 4.1.2 right now...
1. Whenever I try to officially update to 4.3 through the settings, it downloads, then when installing it ALWAYS fails at 25%.
2. This is a big issue. My data connectivity is gone. I have no 4g access period. If I'm not using a wifi network, I can't do anything online, period. I've reflashed numerous times, and can't get it to recognize the network. I can make calls just fine, just no data.
I've tried wiping data and going to factory reset, but this doesn't help in any way whatsoever. I've popped out the battery and sim card and reinserted after a few minutes, still to no avail.
The funny thing also, last night my friend, who has the same phone, updated to 4.3 and got the EXACT issues I've been dealing with. The ONLY thing in common is that we have both rooted our phones in the past. When I first got 4.3 it worked fine. It wasn't until I rooted that these issues began. My friend's phone was not rooted, however it had been in the past. I'm thinking that this 4.3 update has an issue with phones that are rooted or have been at some time. I don't know how it can tell, but that's all I can think of. his phone now is also a doorstop, like mine.

K, fixed data connectivity from another thread here. For some reason, even if I wipe my system, it seems to still keep settings intact. In this case, nothing set in APN. Seems the more I try to fix my phone, the more problems show up.

If you updated to official 4.3...then yes ...a whole new host of problems are yours until the devs figure out the locked bootloader and it's knox flag...
Backups won't restore....and so forth...
Read around ....you'll see...g

[Q] Wi-Fi Stuck on 'Turning On'

Hey guys,
so I've been using my Xperia Arc S for over a year with no problems but recently when I try to turn on the wifi it becomes stuck at 'turning on'. The same thing happens with the bluetooth. Sometimes when I restart the phone it works but most of the time it doesn't I've tried factory resetting it and it worked fine for a bit but then became stuck again. I'm running stock 4.0.4 rooted.
It started happening when I went overseas where my sim card didn't work and I had to change the time zone manually in settings. I read somewhere that this happened to someone else who did the same but there was no solution found. Does anyone know how to fix this? Any help will be greatly appreciated, thanks :good:

It may be hardware problem or software. If you tried factory reset then you should try a new Rom. If problem keeps going, your phone may be the problem, you should bring it to repair service for diagnosing.
Hope it help!

Repair firmware with PC Companion.

I tried repairing it with PC Companion but still no luck. I guess it may be a hardware problem like motlanvamaimai suggested.

Same Q

Hey guys.. I faced similar issue in my AMOI 820 based Indian local device Micromax (rooted + custom kernal)
I fixed this stuck wifi problem by uninstalling Google apps in system by removing them using Titanium back up + and again installing them from playstore if needed.. Hangouts(in my case) if it's a system app after getting updated is the culprit .. Try removing it and reboot and test it yourself..

[Q] No IMEI and Baseband and also a weird stutter on Lollipop

Hey there.
Okay so, I rooted and installed TWRP using Odin on my Note2, and of course, I tried CM12, and also a lot of lollipop ROMS. I'm not much of a noob so I guess I didn't miss anything important, clearing cache, factory reset, did all of it, now the thing is.. I get this weird lag/stutter kinda thing that happens randomly followed up with a vibration, I noticed things like, no IMEI and baseband, so I followed a friends advice who had a similar problem on his G2, he fixed it by backing up EFS from a working stock ROM and restored it into the custom Lollipop OS, this worked for him, now I tried the same thing, but it doesn't seem to help, also I noticed that the "vibration intensity" setting is blank, just like IMEI and baseband. Whenever I put the phone in PowerSave mode from the "RESSURECTION ROM" which disables all sorts of vibrations, the stutter/lag disappears.. It only happens when vibrations are enabled on balanced or performance mode. Now I really wanna know how to fix this so I can use Android 5.0 on my Note2. Thanks in advance

HTC M8 - EE UK - systemui stopped working after factory reset

Hi everyone,
Looking for a solution to my stock, unrooted M8. Carrier - EE.
Android 6.0/Sense 7.0. Software 6.12.61.4
Have had the phone nearly two years so undertook a factory reset to clear it out. Initiated factory reset through settings in the normal UI.
Factory reset completed. Got the welcome screen etc. However, no nav bar, no status bar (with clock, battery at top), and no notification pull-down. Black screen (no default wallpaper), but all standard apps present.
Attempted factory reset again from bootloader. This time, as soon as it booted to the home screen, I got the error com.android.systemui has stopped unexpectedly. Regardless of whether I pressed "send" or "don't send" error report to HTC, the error message disappears and it begins to flash between a black screen and the default sense 7.0 wallpaper - but no sign of apps, icons, etc. The power button is responsive and displays the power off/restart options.
Reset a third time from stock recovery menu. Same result. Have also tried clearing cache, etc.
Weirdly, it optimises what I take to be a number of default apps each time during the factory reset - don't know if that's normal or not.
I'm assuming that my copy of the OS in the recovery partition has got buggered up somehow. But I'm new to this whole flashing/rooting business and most of the guides I've found seem to presuppose that I'm trying to get back to stock from having rooted my phone and installed something else, and I don't really understand them.
So -
1. any ideas about what's happened/how to fix it? I've spoken with HTC but they want me to send it in. 2-3 weeks!
2. assuming that I just need to reinstall a clean version of the software, how do I go about doing that? How do I know what the right version is, and where do I get it? Can I reinstall it without rooting the phone and installing a custom bootloader?
I did have a hunt through previous threads. The closest I found was this one http://forum.xda-developers.com/htc-one-m8/help/ui-htc-one-m8-t3024485 but it still leaves me uncertain about how to find the right software and actually install it.
Thanks very much in advance.

Okay, solved - somehow.
Formatted and removed SD card, just in case. Factory reset again, no joy.
Then also removed sim card, and factory reset again from stock recovery. This time performed cache wipe immediately before factory reset - whereas before I'd wiped cache, restarted, confirmed error still present, then factory reset as a second step.
Systemui and nav/status/pull-down bars all present as normal this time.
I find it hard to believe that the presence of the sim card could have made a difference, so I assume that the cache wipe and then immediate restart did the job.
Anyway, resolved now. Happy days.
