[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.

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.

I've never heard about anyone having this problem. I'd wait until alerts stopped working again, then check SMS settings to see if any of the settings somehow got changed. If they remain unchanged, I'd perform a cache wipe, dalvik cache wipe (multiple times for both) and reboot the phone.
If that doesn't work, nandroid backup, wipe data, cache, and dalvik (multiple times) and re-flash the ROM. Other than that, I can't think of anything else that would help. Good luck!

Same thing happened to me..first make sure youre profiles arent conflicting with the system settings, then make sure you have a match with ruu (which is what fixed mine)

i checked the profiles and all the settings are set to no override for the text messages. whats the ruu?

Perhaps your SMS app is being dumped due to low memory. You could give this a try...

[Q] Massive time drifts, any ROM.

First of all, hello everyone.
Few days ago I bought used htc Desire phone. In the next day I noticed that my clock drifts off the real time.
It takes 68 seconds for a minute to pass and it realy pisses me off, since I've missed so many classes in past few days because of that.
I've flashed numerous ROM's and nothing changed. I've been trying with 2.2.2 stock, 2.3.3 stock, Mildwild based on oxygen, Runnymede AIO, Runny RSK, some ICS roms etc,etc,etc. Every damn time that happens.
Before every flashing I perform full wipe and wipe dalvik cache. I even falshed stock hboot to CM7r2 in hopes it would change something. The only solution is app ClockSync but since i'm not on Data plan I can use it only when I'm home.
Is there anything I could change in software of whatever to make it count correctly? Also I tried TimeZone Fixer but nothing...
ATM I have installed official CM 7.1

very very strange behaviour
hboot will have nothing to do with time...only modifies partition spaces. it's strange that it's occurring on any rom, which makes me think it's something to do with phone's internal clock.
there should be an option in settings-> date and time-> automatic
make sure the automatic option is checked, it should poll the network provided value, don't think it uses any data?

I've checked, unchecked it and it doesn't change the time at all. Is it possible to change phones "Automatic time" source?

Don't think you can change the source as it's from your network provider. Only thing I can suggest is to reboot after you've re-selected that option.
I don't want to sound dismissive, but you could use a proper watch and alarm clock if this strange problem persists. The solution is not always within the phone

[Q] ran into some trouble installing freeXperia on Xperia Pro

Hey, everybody.
Had some trouble recently, after a second install of CM10 FreeXperia (version 244) on my Xperia Pro phone. Suddenly, I noticed that the device won't charge when I plug it in (unless I turn off the phone), and that mobile data isn't working anymore. And I'm kinda clueless as to where to go from here. Here's the story;
I've had the device rooted for a month or so, and a few days ago decided to switch to the FreeXperia rom.
Did an install, everything worked fine. Had it running nice & smooth for 3 days, no problem whatsoever, then got an impulse to switch DPI settings. Downloaded "LCD Density Modder", set DPI to 220, and the device was now stuck at blackscreen during boot.
I decided the best option for me would be to reinstall the FreeXperia rom, get everything clean again, and start over without fussing with DPI settings. So i booted into CWM recovery, did a wipe cache, wipe data/factory reset, installed the FreeXperia 244 zip again (aswell as correct gapps), and had everything up and running again!
Atleast that's what I THOUGHT... but by evening, I discovered:
1. the phone wouldn't charge when i plugged it in.
Tried several different chargers, none works. HOWEVER, the phone recharges it's battery when i turn it off.
and,
2. mobile data isnt working, only wi-fi.
No settings changed, looked them through and couldn't find anything obvious (as far as my knowledge goes).
Making calls and sending sms still works, though.
So, I'm a bit stuck here. I'd be extremely glad if someone could give me a few pointers, or instruct me how to do a "proper" re-install (since i assume my way of re-installing things caused these problems).
Anyone got suggestions?

What I tried again now was:
1. wipe everything
2. flash new kernel
3. wipe everything
4. install rom & gapps
5. wipe everything again
However, the problem remains exactly the same.

Download the ROM.zip again, could be a problem with the zip file. Make sure you do a clean install.

Thanks for the tip!! managed to fix it though, through:
1. charging issue resolved itself by doing the aforementioned wipe-install-wipe procedure, and
2. internet issue was resolved by manually entering APN (it had somehow been erased).
so, we've got ourselves a happy ending, here.

My GPS is screwed after playing around.

I recently rooted and flashed a recovery on my M8.
I was experimenting with the Fake GPS Free app, and mock locations. Worked great.
But when I turned it off (developer settings, mock location-->None), Actual GPS doesn't work right.
Turned it off, removed mock location setting, deleted app, re-installed app, made sure it was turned off, deleted again.
'High Accuracy' sorta works. It gives an approx position. But using something like google maps navigation gives the message 'Searching for GPS...' and never finds it.
I tried a couple of apps 'GPS Status' and 'GPS Reset Com' which reset A-GPS, but it hasn't worked.
'Device Only' fails completely.
Tried clearing cache.
I even flashed a new ROM (Android Revolution HD (6.0)) but no luck.
I do have a factory reset option - but I'd rather avoid it if possible.
Anyone have any ideas of what else I can try?

Restore the nandroid backup you made (you made one right?) before flashing a new ROM or playing with apps from /system

I actually did not make one. I've just been reading up what it is and what I should have done and now I feel a bit silly.
When it said 'backup your phone' I thought it was just the contents (messages, data, media, etc).
Oops!
It's still all a bit new to me..
Anything else I can try?

Backup your data and sdcard content then flash appropriate RUU, if it's not gonna work it's probably an hardware issue.

I have exactly the same problem with my M8. I tried exactly the same steps and still have the GPS issue. I also restored a previously made backup and did a clean flash of CM13... this couldn't solve the problem.
It can't be a hardware issue
UPDATE: I don't know if it would have worked before, but after reflashing I placed my phone on the ground outside, started GPS Status & Toolbox and waited for a GPS signal. after ~1 minute GPS signal was found and it works fine since then. Maybe I was just too impatient before.

Looks like you are new to the modding world. But if you are modding the phone (root, custom ROMs), you should always be prepared to recover from a factory reset (have your data backed up).
And if fact, if you are flashing ROMs without doing a factory reset (within TWRP) you are inviting all sorts of random bugs. In other words, the default wipe in TWRP (data, cache, Dalvik) is always recommended when flashing a new ROM.
