bluetooth wont work

i did the ota Gb update but switched back to froyo the other day cuz i wanted my barnacle wifi tether to work but now my bluetooth wont work. i restored from a CWM backup and tried a plain old factory reset and bluetooth didnt work with either one. i tried to turn it on with the toggle switches and in the settings but it does the lil loading symbol and then nothing turns on.
does anyone have any tips or other setting things i can try? what are the chances of the bluetooth hardware breaking? any diagnostic apps i can use to check things?
ok so after trying different restore points and factory resets, i tried to do the ota gb update again but it failed multiple times. so i flashed the sbf again to completely remove the traces of rooting but that kinda failed too. lol everything seemed to work and i got the 'pass' from rsd but my settings and everything was the same and i didnt do a restore but now bluetooth works
SBF doesn't necessarily erase your /data partition.

[Q] My wifi is dead are there any fixes?

I flashed cm9 last night and everything was fine it was a nice test build but I wanted to go back to stock. I restored my backup of Virtuous beta 1 and now my wifi is trying to turn on forever.
Basically it says that "turning on wifi" but it never turns on....
Is my tablet now a very expensive paper weight? Or is there a fix for this?
Same happened to me last night, after trying a few different ROMs including CM9 as the last one. I went back to my ICS rooted via nandroid restore. Wifi would not turn on. So I just booted into CWM and flash the same ICS rooted ROM again (without wipe) Rebooted and WiFi back.

[Q] Wifi not working after rooting micromax A52!!

I recently flashed stock rom of micromax A52. There were no problems. I then also created a backup of stock rom using clockworkmod but then when I install any custom rom with root on my phone, my wifi started working incorrectly. It starts but as soon as I try to use it, wifi disconnects and shows the wifi which it out of range(although it still there). I tried to restore the backup but now with it the same problem occurs. Will I be able to restore back it? Please help me....
phone not working

[Q] Xperia SP Wifi Doesn't Turn On After A Reboot After Factory Reset

I had the 'Can't Establish a reliable connection to the server' issue on my Xperia SP [C5302, Android 4.3, Build - 12.1.A.1.205, and rooted, of course]. So, I tried factory reset and it didn't work until I installed Lucky Patcher and reset the hosts file to original state. Now, Google Play works.
But there's another problem. On the first boot after reset, wifi worked fine. But ever since I rebooted it, wifi has stopped working. The wifi slider is kinda unresponsive (have a look at the screenshots I've attached).
Does anyone have any solution?
Restored using recovery. Problem solved.
Okay, after trying many different things in vain, finally restored my phone using an old backup I had. Done!
Same issue with any JB rom used with multirom as secondary rom. Searching for resolution please...

Note 4 wifi will not turn

I recently bought a note 4 DE from ebay and it came loaded with jsmine rom. I was excited none the least but i noticed the phone would get really hot after a time and decided to switch to cyanogem 13.0. The first thing i noticed wad wifi would not turn on so i twrp recovered a backup and all was good again but still getting hot so i tried to upgrade to jasmine 6.0 and once again the wifi wouldnt turn on. Restored twrp backup and now wifi will not turn back on at all. Everything else works. Factory restore doesnt fix it. What should i do?
