[Q] wifi - unable to scan for networks

Hi Guys
I have become a victim of the dreaded "unable to scan for networks" wifi issue and need some suggestions.
The problem originally occured when I upgraded my phone to MIUI-Au, I also upgraded the radio to the recommended version.
When I enabled the wifi after the reflash the phone went into a reboot loop which I could not get out of. I reflashed the phone again with MIUI, everything worked fine until I enabled the wifi and then ended up in the loop again.
I did some looking around and found the suggestions to rename/delete the /data/misc/wifi/wpa_supplicant.conf file which I tried to no avail. I gave up with MIUI and decided to go to another Rom and decided to try out InsertCoin CM7/A2SD+. I installed the rom as per the recommended procedure i.e. Wiped Malvik and normal cache partition & data/factory reset. I also tried both of the recommended radio's on the Insertcoin thread.
My system now no longer gets into a reboot loop when trying to enable the wifi but simply comes up with a "unable to scan for networks" message and then switches the wifi off. I have tried resetting data/ factory resets, Cache and Malvik settings and everything else I could think of.
Has anyone got any other suggestions as to how I could try and sort this out as I have followed all the suggestions I could find on the site?
Thanks

Did u try only a factory reset without data wipe? Usually a factory reset solves the problem...
Maybe this might help:

First, perform a Nandroid Backup via Recovery Mode, which you can later restore, just incase anything goes wrong.
Try flashing the modified kernel 2.6.29 in Recovery Mode (MCR_oc_v14-signed.zip ), it should work then.
Here is the link to the kernel thread: http://forum.xda-developers.com/showthread.php?t=682419

Thanks for the suggestion MatDrOiD. Yes,I have done a factory reset, if that means setting/SD & Phone Storage/factory data reset (tried with "erase SD card" ticked and without ticked). Have however tried your suggestion again but still comes up with the "unable to scan networks" message.
I have also reflashed several new roms (in default settings) in an effort to try to find something that would work, all seem to have the same problem.
I also tried with a different SD card with nothing on it and have reformatted it several times.
System info
Kernel version 2.6.35.10-gdd56551 [v03]-snq-is-still # 1
Build Number: IC GS A2SD+ V20
Software number 2.36.405.8
Android Version 2.3.3
Rom version: InsertCoin_GB_Sense2.1_A2SD+_v20
Radio: 32.56.00.32U_5.17.05.23 tried 32.56.00.32U_5.17.05.08 as well
Would changing the radio make any difference? I have tried the versions recommended for MIUI as well.
Anything else I could try?

Changing radio could work. At first, i would do a full wipe and flash the original htc froyo rom. If the issue still exits, wifiadapter could be broken.

Thanks for the suggestions Mat, I tried to reflash the 2.6.29 kernal as suggested but my phone seems to just sit with a black screen with white stripes on the edges when trying to restart with the new kernel. Left it for 1/2 hour but just sits there. Also tried a few other versions of the kernel but all seem to just sit with the white stripes on the scree.
I am going to carry on trying over the weekend and if I don't get it sorted will switch back to the orginal HTC froyo ROM and see if that sorts out the problem. If not will send it back to manufacturer
Thanks again for the suggestions.

[Q] n7105 tock android 4.3 nordic: bluetooth problems

Hello everybody,
I'm running the latest stock Android 4.3 on a rooted Note 2 with CWM installed. What happens is that when I use the phone to make or receive phone calls (streaming music is ok instead) in my car (but I experienced the same problem in another car) the Bluetooth all of a sudden goes off and I need to either turn the screen on or toggle the bluetooth button.
Any idea on how to fix it?
Thank you,
Davide

Hi! Have you tried a Factory Reset? It will wipe your phone clean, so back-up your stuff first. Come back after with the results, maybe this will fix the Bluetooth issue.

Actually I wanted to avoid that...

Okay, so let's try something else first and see where it leads: Go to CWM and make a Nand Backup. Then wipe your Cache and Dalvik Cache. Reboot and test. Most probably this will not solve, but it's worth trying. Get back in CWM and this time wipe Data + Dalvik + Cache (Factory Reset basically). Boot and test. If not working, you can restore the Nand Backup to get back your apps and data. If it is working, well, lucky you, you'll have a great time installing all your apps back

Can someone help me???😭😭😭

I'm unable to connect through wifi on asus zenfone 2. I have tried the suggestions given in net but it didn't help me that much. It keeps on connecting and dropping then reconnecting. It's really frustrating me a lot. . But it worked fine for me before. Not sure it's because of latest firmware update or not. If anyone had this problem and rectified it means pls let me know the solutions. Thanks in advance.

The is commonly caused by a corruption in data when installing or updating room, I would do a hard reset and flash a new room, the head reset can take along time so wait for it to finish or you will soft brick your device

Unexpected Reboots

Hello,
It seems that my G925T has some problems with soft reboots. I don't know exactly what the problem might be, maybe you can help me troubleshot.
So I have followed up all the things a normal user might do like:
soft reset, hard reset, odin stock rom flashing, smart switch disaster recovery, disabling certain apps, going to safe mode, cleaning cache, resetting cache and dalvik, but nothing. Flashing a different custom rom, custom kernel but still problem remains.
Even after following up with all these steps, my phone still reboots unexpectedly while I use it and even i don't use it. An average is that my phone gets these unexpected reboots like everyday. Maybe 3 time a day, or maybe next day. It seems like soft reboot.
For an some addition information my phone is IMEI repair, but everything is fine, i can get updates as i am currently on the official stock ROM.
Currently I am on latest update DOJC.
What do you think it might be the problem ?
Has soft reboots to do with IMEI repair ?
Is there anyway i can troubleshot this ?

Solved: Wifi on while Airplen mode On

Hi,
I've just updated to Android 11, not clean install, just recieved OTA and intalled.
I have noticed no problem so far, but when I turn airplen mode on, my wifi is still on. Any clue about what is happening? may it be related to a not clean installation?
Solved: Wipe cache solved the issue.
