Wifi "Unable to Scan for Networks"

My wifi is always turned off, and when i enable it. It turns on for 5 seconds say "unable to scan for networks" and then turns off.
if anyone have encounter the same problem before and know how to fix it. it will be great.
thanks.
my phone is rooted and i'm runnig LCR 1.8.2

my phone does the same exact thing, It has done that since the day I got it.
In my case it is a hardware problem. I got my phone on ebay, I registered the phone with acer and had a 1 year warranty, but they said I had to take it back to the store where I got it from, so a warranty claim with acer isn't going to get you anywhere.

My liquid got the same problem too.

"Unable to Scan for Networks" SOLUTION - WITHOUT ROOTING
**** SOLUTION - WITHOUT ROOTING *****
I searched many forms to solve the "Unable to scan network" issue. All explained how to do it after rooting and I did not want to root my phone.
Yesterday, while playing with the phone and SDK, I could repair it by deleting "bcm_supp.conf" file. This is what I did:
1. Install the android SDK.
(make sure the <SDK>/tools path is added to the windows path variable. My Computer -> Properties -> Advanced -> Environment Variables -> System variable -> add the SDK path at the end of Path variable )
2. On your phone, please enable (tick mark) "USB debugging" under "Settings" -> "Applications" -> "Development"
3. Connect your phone using USB to PC/Laptop. Close phone manager application if it comes up on the PC.
4. Run "ddms.bat" from <SDK>/tools directory. The DDMS application will come up and it should readily connect to your phone. (in the main screen, under Name, you should find the phone ID and SW ver. no.)
5. Go to menu Device -> File Explorer. New window will come up.
6. Here go to data -> wifi directory. You will see a file bcm_supp.conf.
7. Though it is not possible to read this file, you should be able to delete it. (at least I could delete it). You can delete the file by selecting it and then pressing red "-" on top left of the window.
8. Now close the DDMS and disconnect the USB. Enable WiFi and scan for networks. The bcm_supp.conf file will get created and you should be able to find the networks.
Please note:
1. Do this on your own risk.
2. All your previous WiFi settings are gone as you delete the file.
3. If you don't know how to install SDK, just google, you will find many forms explaining.
4. I tried to delete the file from "Terminal Emulator", but it did not allow. I guess DDMS has some special permissions.

i think this method is for the samsung galaxy S,because i tried it for my Liquid and there is no folder called wifi in /data, the only folder called wifi i found it in /data/etc/wifi and the folder is empty there is no file on it

[Q] Kies failing firmware update, auto-disconnecting, need help!

Hey guys,
I'm trying to update my gf's Galaxy S to JP6 via the latest Kies 2. The program connects initially and notifies about a firmware update.. accepting this brings up some T&C nonsense, choosing 'accept' brings up a box asking what to backup, at this point whether I backup or skip it will bring up an error about failed update, i9000 disconnected etc...
I've uninstalled & reinstalled Kies, no difference, can anyone suggest what the issue is and how to fix it?
It's UK O2 Branded, currently running JP5 (which was updated by an older version of Kies v1.5 that worked on Win XP). The PC in question this time is running Windows 7 64bit. I rooted the phone using SuperOneClick and had installed RyanZA's OCLF v2 from the market.. i've undone the OCLF now though.

Kies and Win 7 x 64 i have never got it working . But have on Win 7 x32 .

Try to run Kies as "administrator" with "windows xp compatibility mode".

End to the Noob Bashing...
Just realised that i was looking at the wrong post when i posted this data so the reasons for posting bit at the top of this will make no sense....sentiment still true though. Hope it helps either way.
Ok, i'm a Techie. I know without a shaddow of a doubt that my Laptop is fine in every respect and yet it was doing this to me also.
Believe me when i say, you're not insane, and despite what others say you DO have a valid question which DOES deserves a valid answer...ENOUGH of the trollish Noob bashing 'non answers'.
If you are having the EXACT same issue as the original poster, heres what you do:
With your phone unplugged....
Update Kies:
Make sure you have updated Kies to the most recent version. Either do this by going to your mobile phone opperators website and downloading the updated software version directly or by using the help --> Check for Updates option. Latest version at time of writing is: 2.0.2.11071_128.
Once up-to-date, close Kies. Although probably not essential, use 'Task Manager' to end any Kies related processes.
Uninstall Samsung USB Driver Software:
1) Navigate to Control Panel and open either (Windows 7/Vista) 'Programs and Features' or (Windows XP/2000) 'Add Remove Programs'
2) Scroll through the list of programs to find one called 'SAMSUNG USB Driver for Mobile Phones'. If it is installed, right click it and select 'Uninstall'
3) Run through the process of uninstalling the software.
Tidy up Devices:
1) Right Click 'My Computer' select properties
2) On windows 7 (possibly Vista also...dont know as I skipped that generation) ONLY, select the 'Advance System Settings' option over to the left of the window.
3) Select the 'Advance' tab in the 'System Properties' window that appears.
4) Click 'Environmental variables'
5) In the 'System Variables' section of the window that appears, click 'New...'
6) In 'Variable Name:' type 'DEVMGR_SHOW_NONPRESENT_DEVICES' without the quotes
7) In 'Variable Value:' type '1' without the quotes
8) Click 'OK' times 3 to exit the windows you opened
9) If Windows 7 (or Vista) close the 'View basic information about your computer' window also.
10) Open 'Control Panel' and navigate through to 'Device Manager'
11) Click the 'View' menu and select 'Show Hidden Devices'. This will display all mothballed devices i.e. those devices which have previously been plugged in but then removed. Windows stores a record of the drivers in the background of the system to speed up the process of installing the device drivers when you next plug in said device. Sometimes, in the case of Network Cards for example, not only will it store the drivers but it will also store its settings. This can cause a problem as if you were to plug in a replacement Network Card and set it to use the same static IP address, the mothballed device will clash with the current device. Without the environmental variable setting being configured as above, even when you show hidden devices, mothballed devices remain hidden.
12) Starting from the top, expand each of the branches in the tree to see the devices within them.
13) Look for anything with a 'Samsung', 'MTP', 'GT-I9000' prefix. If found, right click and select 'Uninstall' and confirm at the prompt. BE CAREFUL NOT TO UNINSTALL ANYTHING YOU ARE UNSURE ABOUT. Google it if need be to figgure out what it is and if its not a Samsung or android related device then leave it well alone.
14) Close Device Manager once you have assessed the final branch.
Re-Install Samsung USB Driver Software:
1) Open Kies
2) Expand the 'Tools' menu and select the 'Install Driver' option.
3) Click ok to any prompts to fire off the process.
4) Wait for it to complete.
5) On completion click 'Ok' to acknowledge if required.
At this stage, it may be worth turning off your Windows Firewall and AV scanners just to be on the safe side. Probably not an essential step but may make a difference. If you're not confident enough with computers to do this then dont bother.
Re-Connect Samsung Galaxy Device:
1) Plug the Micro USB cable that came with your device in to ANY of your most trust worthy USB sockets.
2) Plug the other end into the Micro USB socket of your Samsung Galaxy S.
3) Allow Kies to pickup your device and display the storage information proving it is properly connected.
4) If an update is avaialble for your device, Kies should prompt you. If you are confident that you have all the data backed up onto your computer, then proceed with the Firmware update.
5) Click either the Backup or Skip Backup option.
6) Panic a little when the device appears to disconnect YET AGAIN!
7) Chuckle to yourself knowingly once it blasts through this onto the update.
8) Once completed unplug from and re-plug your Samsung into your computer again.
9) Upload your backed up data.
10) Get rid of the God-Awful default dasktop layout that your Mobile provider forces onto you.
SORTED!
Dont know what causes this but what i have noticed is that once you have tidied the mothballed system devices related to your phone and re-installed the device drivers again, it appears as if there isn't any devices named with the prefix of 'MTP' in the device list but there are a few more labelled with a 'Samsung' prefix.
I suspect this is something to do with Samsung at long last fully qualifying their own drivers but not bothering to tidy up the mess that the old devices left behind as part of the Kies update process. Either that or Windows prevents the Samsung USB Driver installer software from being able to delete/update existing Samsung devices.
Enjoy!

I wish I could say this worked for me... but alas, it has not...
This is from a post I entered earlier today... (no change from this either)

... steps that worked for me
1, downloaded MyBackup (free version)
2, did backup of both apps and data (put both on ext memorycard)
3, used the restore to factory option under privacy in the settings menu
4, unmounted internal sd card and formated it (to remove the mtp loop issue)
5, run kies,
6, select update firmware,
7, at the box where it says no device connected, put into test mode (ctrl + alt + U + P)
8, connected phone
9, detected thaqt there was an update to JM1 available
10, started update,
Click to expand...
Click to collapse
I have yet to do any of this (other than get a backup using MyBackup), but have some questions... (noob here)
Step 3: Will this remove all the definitions for my phone number and/or provider as well?
Step 7: the CTRL+ALT+U+P thing doesn't work with Kies 2.0.2 so if I am unable to do an update, will the phone be at Froyo (2.2) as it is now? or does it revert to 2.1 (which it was when I bought the unit)?
I also got this "Informational" record from the Event Manager... (I could hear the system connect, then drop the Kies connection)

Well had to go through Samsung Support... they got me to reset to factory default (since I had a backup) then do the Kies update...
All is better although it would be nice to know what had gone wrong...

[Q] Big problem

Hello,
i had yesterday rooted my LG Optimus Black, after that was all perfect but at the evening i got a big bug.
They didn´t find my sim card. I searched for many solutions.
I have a good one with smart flash but i cant click at Erase Entire CP but i have WIndows Enabler active.
What can i do?

Hello. Just wanted to clarify. You mean that you cannot connect to your mobile network? Any other changes besides root?
Sent from my LG-P970 using xda app-developers app

only root and zeus v7 rom installed
the lock screen shows No sim card and security failure.

click twice on the button
really make sure windows enabler is on
are you on 64 bit or 32 bit?

i have win 7 64bit
after 2 clicks it isn´t activ at smartflash i try it in the next half hour but i think it had to be active to work.

Don't erase entire CP. It damages a partition that can't be recovered (Even with SFT) and a repair person might refuse warranty if they notice.

i have no warranty it was a present but i can´t use sim cards at any kind of rom its say the same.
At a german board the say you had to erase entire cp and after that change the imei to your original imei.

Still damages nvram. If warranty is not a issue then you can go ahead.
Sent from my LG-P970

Sorry, since I needed to do that last year, I'm curious about what damaging nvram implies xonar_ ? Thanks.
Sent from my LG-P970 using xda premium

what's the thing with nvram xonar?

When you wipe CP it wipes nvram partition on your phone ( or at least part of it). All data like mac address of and IMEI are stored there. This data isn't touched by reflashing with SFT. It's possible to read that data from phone to restore it since it's hardwired to the phone, but kernel 3 only reads it from nvram partition. Rmcc made changes to the kernel to make a dummy address if the mac address is zeroed out to allow people with corrupt nvram to use wifi. I don't know if the kernel then later reads it from phone self, but it could cause some problems with wifi and bluetooth.
If you tried flashing the official firmware of KU5900 (kdz or bin not the repack) and didn't change it to fits our device then it also corrupts nvram.
Its possible that ticking wipe CP only wipes the first bit of nvram where the IMEI is stored. There is two entries in nvram that contains IMEI and replacing both of them could 'repair' it then.
I made a backup of my nvram incase something like that happens.
LG R&D tool might fix this,but I'm not sure. It takes forever and I'm making the assumption it's because it does more than SFT.

Here the guide of the german board.
Here is a summary of my approach: (Before installing the SIM card process!)
1) Smart Flash tool load.
3 loading) The image of the LG P970 V20B page.
4) Smart Start Flashtool
5) Erase entire Ap select and process restart select (Previously appropriate COM port) The port will be displayed only if you have installed the drivers and the LG hidden menu of the smartphone "AP CP USB Switching" and "CP USB" selects.
5) Windows Portable load start, and enable the bottom of the icon menu with a simple click.
6) The Windows Portable you have the opportunity to shaded box "Erase entire CP" enable the Smart Flash tool.
7) You select the pre-loaded CP and Ap-bins and start the process. (Before you have to take the battery off the phone, disconnect USB cable, hold the loudspeaker key pushed up, tuck USB cable again. Then the phone is in programming mode, and you can put the battery back.
8) Now click the Smart Flash tool easy to start. After about 5 minutes the process is completed.
9) You should see the SIM error be gone.
10) Note: Since absolutely everything in this process will be deleted right, not the IMEI! This can be changed using a HyperTerminal program again. The right is under the battery.

If everything is deleted then your MC address will also go poof. It can be put back into nvram quite easily. Make a buckup of your nvram so that you can get your Mac Addresses out. (You can get them other ways aswel but I think this is easiest way.)
Code:
adb pull /dev/block/mmcblk0p11 /WHERE_YOU_WANT_IT/nv.img

i have no idea how i can i do it.

[SOLVED] Unable to back up NV Data on S3 i9305

I purchased an unlocked, unbranded i9305 S3 LTE and have not been able to back up the NV Data.
I tried this with it completely stock and even though I have tried both settings with DM in Qualcomm USB settings and the port is found in QPST it always says 'No Phone'.
After trying this on several computers, I then installed Clockwork Recovery Mod and Rooted the phone successfully, and still had no luck connecting with QPST with the same 'No phone' message.
I also tried using EFS Pro and the Qualcomm NV Tools, the phone says at first it is connected but the program freezes and then says the phone has disconnected. I tried unticking 'Read Phone version information' and it connects. But as soon as I try to read any data the Rx Tx indicators flash a couple of times in the app and then I get the same Phone disconnected message.
Can anyone help? I have searched here and online and found lots of similar cases but no solutions...
Thank you very much in advance.

I don't own this phone but are you sure you have a Qualcomm processor? From these 2 pages:
http://www.morecellphone.com/phones/samsung-galaxy-s-iii-gt-i9305/304
http://www.gsmarena.com/samsung_i9305_galaxy_s_iii-5001.php
it should have an exynos processor, so those qualcomm tools won't work. (think qualcomms are just some specific models)
Can't you just get into some custom recovery, adb to it from your computer (or terminal emulator) and 'dd' an image from the /efs partition out of it (needs root)?
How i did it:
Opened terminal emulator and typed "mount" to check my mounts. Looked up the one that had /efs on it. It should also say something like "/dev/block/mmcblk0p3" (this is the one on mine, use whatever you got from "mount"). Then do something like:
su
dd if=/dev/block/mmcblk0p3 of=/sdcard/efs.img
where the "/sdcard" is the directory where you want your efs image to go. Then you just need to copy the efs.img file to a safe place and you're done.
If you need to recover just do the opposite
su
dd if=/sdcard/efs.img of=/dev/block/mmcblk0p3
Careful with the "if" "of" order, and with what you type. dd is a powerful command and it's easy to screw up irreversibly if you overwrite a different partition by accident.
Another method, I've manually copied /efs file contents with root explorer to my sdcard and later to my computer and was able to use them to recover my phone (had an app wiping my /efs by accident).
This is how i did on mine and worked but i've heard those qualcomm's (if you really have one) have a different method and what i'm saying may simply not apply

Thank you for your response. Unfortunately even though it does not have a Qualcomm processor it does use this chipset for the modem I believe.
I've been following the instructions in this thread http://forum.xda-developers.com/showthread.php?t=1946915 but not having any luck. The phone is fine but it is not recognised correctly in QPST or EFS Pro....

IMEI and BaseBand Version Fix Works 100 %

Lately i've been watching people as well as myself screwing imei and not getting reception.
There are two cases possible
1> You screw only the IMEI
2>You screw the baseband version also ( which in some cases makes the mobile lag )
Lets start with fixing the baseband version nothing can be done with a simpler way you just have to flash the stock firmware again and the next time you boot the baseband version will appear.
Imei Fixing
Prerequisite
** Make sure you are using Stock rom and Locked Bootloader
1> Install PDA Net and CDC Drivers*
2> Install MauiMeta 3G Software*
3> Download MTK 6582 NVRAM Database* (The Chipset our phone is using )
After you are done doing all these things
1) Open MauiMeta App
2) Click on Action select open NVRAM DB, A popup will appear navigate to the database files downloaded and select the db files and select the files starting with APDB... and the next time BPLG...
3) Click on Option on App and select "Connect Smart Phone In Meta Mode "
4) Select USB COM as your host and click on Reconnect
5)After doing this switch off your phone and connect it if drivers are installed properly the phone will boot in meta mode and the window besides the USBCOM will be accessible click on IMEI Tool if NVRAM DB files are asked provide it
6) Write the IMEI from the Mobile Phones Box (Behind) in both the tabs and press Upload to flash
7) Restart Phone
Voilà IMEI Appears and you can now get Network Signal
AS THIS IS MY FIRST POST AND I HAVEN'T COMPLETED POSTING 10 TIMES IN OTHER THREADS I AM NOT ALLOWED TO SHARE LINKS FROM OTHER WEBSITE WHICH INCLUDE THE SOFTWARE DRIVERS AND NVRAM DATABASE FILE. YOU TOO CAN BE INTELLIGENT AND GOOGLE THEM.
