[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.

[Q] My phone keeps restarting after loading home screen. What should I do?

Hi there,
Longtime lurker, first time poster! Before I get into my issue, I would like to let you all know that I did do my due diligence and didn't find a concrete course of action to address this problem.
Here is what I did (as per Cyanogenmod Wiki)
1. I downgraded the phone to an exploitable version of Froyo
2. I rooted the phone
3. I installed Cyanogenmod 6 (because 7 wasn't working)
4. Installed Google apps for the above version.
5. Market and account wasn't working
6. Found CM version 9 beta
7. Installed that - it worked
8. Installed Google Apps ICS version - worked well
9. I finished doing this sometime in the morning, and the phone worked a good four hours before trouble began
10. I got a call, and post call the call manager (or equivalent Android process) stopped responding. I restarted the phone
11. Since then it has been rebooting after loading the home screen.
12. Post this, I searched online
13. One recommendation was to clear data, cache and restore factory setting via recovery.
14. I also formatted SD card and reinstalled CM 9
15. Issue persisted.
16. I tried another mod (Audacity 3) didn't work and has same issue.
Someone suggested I do a SuperWipe and reinstall the mod.
I would love to hear from you guys in terms of what I can do next. I am sure the device hasn't been bricked - I can still access recovery and bootloader.
Thanks in advance!
EDIT: Found the solution. The phone was rebooting because of an in compatible build of Google Apps. Downloaded the right one from Cyanogenmod Wiki, and its golden!

ive had the same and android revolution, just flash a rom like andromadus beta 4. or another rom

Thanks!
I did do that for a bit. I tried A different ROM but liked CM better. Also, I made a mistake with the build of google apps - which was the reason it kept rebooting. Have been using it for a couple of weeks and it works great.

Problem with mounting

Whenever i connect phone to pc, the option on the phone on whether i charge only or mount etc, doesnt show up. Even after a fullwipe problem persists. I have to mention that this came up after installing v6supercharger, but even after fullwiped and reinstall rom, still cant make it work. Any help will be welcome!
Using GingerSense4 with RCmix3d v12 kernel

Also, the PCSCII.apk is installed, and reinstalled, but the service is not running (under Application-management-services).

Problem semi-fixed. Flashed the PCSCII.apk from this guys thread: http://forum.xda-developers.com/showthread.php?t=1559683&page=9
But you have to untick the "ask me everytime i connect" button on settings, and manually change whatever you want.

I'm having this same exact problem, and tried all the same things; I've been scavenging the internet for a fix, but have yet to find a solution.
In my case I'm on a rooted Inspire(same as Desire) HD, running Android Revolution HD ver. 6.3.1. This problem didn't occur right after any of that though, It's been working fine this whole time up until 2 days ago(to my knowledge at least). "Funny" thing is I've had this happen before with this same model of phone, and that one wasn't rooted.

[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.

[Q] Can't turn wifi on. Tried with 5.1 and 4.4.4

I should mention that this phone is not mine and it was brought to me to fix. It could not get past the samsung bootup animation screen.
So I installed TWRP 2.8.6.0 and wiped everything. Then the first rom I flashed was [ROM][5.1.1][AOSPA] ParanoidAndroid 5.1 (5/21/2015) Then flashed gapps 5-22-15 from euroskank/banks. I wiped dalvik & cache (Is this necessary?) and rebooted.
The intro screen did not let me skip the wifi connecting part (I thought it was a bug in that version) and it told me to turn on wi-fi to connect.
So I tried the same thing with the version before that and it let me skip. After that I managed to turn it on once? But it the phone crashed and soft rebooted.
I tried other 5.1 roms and the wifi doesn't work still. It doesn't let me turn it on. Same with 4.4.4 with cm11. Also, the Wi-Fi MAC address says unavailable. Don't think that's supposed to happen?
Does anyone have a fix?
Edit: I took out the SIM card to see if that did anything. Then all of a sudden the grayed out On button turned blue and wifi networks appeared... But I couldn't do anything else since it made me restart. It stopped working after a reboot :/ Tried it several more times and couldn't get it to do the same thing..

Hope you had read the posts, it should had said the Rom is not "stable"
If your friend are going use their phone for daily driver, then I recommend you not have the 5.1 Roms for now because it's not really suitable for that right now.....
I'm not sure the CM11 you have flashed is unoffical or is offical. Offical onces are still work in progress and have most of the things broke (I think)
Here is a Kitkat Rom for SGH-T989
If your friend really wanted to have a Lollipop running on his/her phone, then I will recommend this one. Make sure you read the instruction CAREFULLY if you do wanted to install this one since it's a bit complicated with it's "virtual partition"
Or, if you wanted it to be just stock. Odin it back to normal, here is a instruction (with video too).
This is all the possible way to fix your friend's phone that I can think of, if you have encounter any error or have anymore question, feel free to reply :fingers-crossed::good::highfive:
P.S: yes, wiping dalvik & cache is a way to prevent any error caused by another old Rom if you decided to flash a new one. It's a good way to prevent error during Rom flash process

Thanks! I'll try the 4.4.4 rom you sent me. I'll post an update when I get to it.
Uh and about the 5.1 you linked. For the virtual repartition part in his post, I couldn't open the phone's internal storage on the computer after formatting it to ext4. So I'm confused about that step.

For the virtual partition, it's best for you to have it on the External SD card. Since TWRP transporting file to Internal Storage after that seems bugged (not working)
