Sammy 4.3 update wifi grayed out and not working - Galaxy S 4 Q&A, Help & Troubleshooting

Hi everyone.
I've been sitting for almost 6 hours trying to get my wifi fixed after upgrading to 4.3 and rooting it etc.
Last time I tried I was unable to stick to carrier network but wifi was working.
This time it was the other way around.
After ALOT of trying and failing, I finally fixed it.
mount -o rw,remount /
and
mount -o rw,remount /system
after this it was just to set permissions, I did chmod -R 777 on /dev and /system/etc/wifi
My guess, without any more checking, is that alot of permissions are set wrong within the image I downloaded from samsung-updates, and the one from sammobile, that is from samsung themselves.
The weird thing is that my father has a 100% stock phone wich got the update, it all worked like a charm.
Min did not, and it was not rooted......until now with knox 0x1 and everything else
Also, I did alot of searching, but the only thing I found was a fix for my modem, wich did nothing for me.
And since I did not find anything else, I figured this might help others in the same situation
Update: the "fix" has to be re-done after reboot.
Anyone has a better fix ?
It doesn't help with full wipe and reinstall.

Hi,
I have the same problem here
How do I?:
mount -o rw,remount /
and
mount -o rw,remount /system
Thx

after mount -o rw,remount /system
do a
chmod -R 777 /system/etc/wifi (I think this one makes the difference)
and
chmod -R 777 /dev
All requires root

I had a similar problem - no matter what I tried, I couldn't turn the wifi on, quick toggle would immediately switch back off and same in Settings. Every time I tried to switch it on I also got a Knox warning. Brilliant, well done Samsung.
I did some reading and it seems you can turn it on if you use a custom Kernel, but by then I'd given up and installed PacMan ROM, which will do until a proper 4.4 comes out.

I have tried two kernels, none of them fixed the problem, so for now the workaround have to work, I'm refusing to flash my phone.....again

Tody I actually had to go back to 4.2.2, I happy I for once did a nandroid backup yesterday befor I flashed 4.3, the phone stopped responding a few minutes after reboot, and gave me a flashing red light i the upper left corner, when screen was on.
After screen went off, the red light changed to a blue light.......
And I just saw that samsung pulled the 4.3 update as well....
I think my nex phone will be a nexus....if they at some point come with microsd slot.....if not.....perhaps going back to my old Nokia 6150, it was rock stable and had a week of power on one charge.

Just signed up for it, but thought I would let the community know about it!
MobileDefense.com > that
..and jesus that video is annoying.
Wavesecure as well............
Just took a quick glance at the three iTag/lifehacker, Wavesecure & MobileDefense. Is MobileDefense the only one that has free features on it?
mobiledefense is the ****. And the devlopers support custom roms.

I second/third/fourth Mobile Defense.
Here's why...
1) When installed as a system app on a rooted device it will automatically turn on GPS to get an accurate location whereas wavesecure will NOT turn on GPS and only use the cell tower location which is not accurate.
2) Their support forum is FANTASTIC, they support custom ROMs and are aware of those ROMs out there and any problems associated with them. I had a few issues at first (none of which was mobile defense's fault) and they had everything resolved in a few hours.
3) Their GPS ping time is very fast. Instead of just sending a signal every minute, its more like every 10 seconds.
4) No international SMS charges like with Wave Secure (although I know wave secure is getting a US gateway soon, still...)
5) The upgrades they have planned are superb (just check out their site)
Sorry for the n00b question but how do I install MobileDefense as a system app on my rooted Hero?
adb push MobileDefenseNameHere.apk /system/app

that wont work...
Put the com.neevo.mobiledefense.apk in your ADB tools folder
Code:
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
chmod 777 /system/app
exit
exit
adb push com.neevo.mobiledefense.apk /system/app
adb shell
su
chmod 755 /system/app
mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
reboot
Done.
I disapprove of the program.
Why you ask?
Becuase it has an i as the first letter in name, and it is then followed by a verb which is then captilized.
Reason why they didn't call our phone the iHero is because it sounds stupid. Hence why apple has the iPhone.
Another Mobiledefense user here. Great program. Excellent for tracking your kids.

[Q] Adding fonts to AT&T original rom - how?

Hi,
I got 4 days ago my new ARIA & this is really amazing machine.
I root the device & also tried installing the latest rom published in the forum - cm-6.0.2.1 but i liked more the originl ROM which came with the device.
The only problem i'm facing with the original ROM is that it doesnt support the Hebrew language so i'm getting squares instead of letters.....
I tried to use DejaVuSans.ttf solution.... the one with the instructions to do in the terminal the following commands:
1. mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
2. chmod 4755 /system/fonts/DroidSansFallback.ttf
3. dd if=/sdcard/DroidSansFallback.ttf of=/system/fonts/DroidSansFallback.ttf
4. reboot
The 2 first command lines worked ok but when i'm putting the dd line (#3) , i'm getting an error saying there is no room on the device & then it gives me 2 lines - something about 0+1 checked in & 0+0 checked out.
After rebooting the device, its not sulving the Hebrew problem, any thoughts?
i want to keep the same rom & not updating it, just adding language fonts....
Eran.
So the current update, after fighting with the device i was able to complete the replacment of the DroidSansFallback.ttf file but it didnt solve the problem, i still getting squares......
Please anyone can help me with that, i really need it.

Guide Wifi Ad Hoc Working Samsung 10.1v

Hi Guys,
I have just gotten Wifi Ad Hoc connection working in the Samsung 10.1v (don't see why it won't work on the 10.1 either)
You need to have adb installed and your Tablet needs to be rooted.
I used 2 threads as reference for making this work:
http://forum.xda-developers.com/showthread.php?t=1069569
and
http://forum.xda-developers.com/showthread.php?t=1033314
As a newbie to this i will show you what i did, maybe someone can clean up the process with a simple approach:
You need to turn on Airplane mode to disable wifi, or you will get an error when trying to copy the wpa_supplicant file later on in the instructions...
I had trouble with the adb push command (shown in the above threads) so I did this instead.
Unzip and copy wpa_supplicant file (attached) to Tablet (I used downloads directory)
Get ES File Explorer from Market
Open ES File Explorer and in settings menu select Root options.
Set Root Explorer and use HiAPK
Then Tick Mount File System, then exit menu and navigate to /system/bin and copy wpa_supplicant to somewhere safe (I made backup directory in storage/ sd memory)
Now copy new wpa_supplicant file from where you saved it (downloads directory) to /system/bin
Now in windows command box type:
adb shell
# su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# chmod 755 /system/bin/wpa_supplicant
# chown system.wifi /data/misc/wifi/wpa_supplicant.conf
# exit
Now reboot and turn off airplane mode and enjoy.
Usual conditions if you follow this and something bad happens please don't blame me i used the above method (with trial and error) which worked for me (but maybe i just got lucky)
Also I want to acknowledge the hard working devs that pioneered the process and created the file - great work!!
Good luck...

what about the usage of battery after install that wpa_supplicant.conf
Because i used to transfer a similar file like wpa_supplicant.conf to help my samsung Galaxy S i9000 to connect the adhoc WIFI. The usage of battery is horrible, I charged my phone whole night and there is no more battery remaining next morning
I will keep you posted, but been using it on ad hoc for a couple of hours now and nothing out of the usual. Battery seems just same as on wifi.
I will leave it on overnight and report back tomorrow
Sent from my GT-P7100 using XDA App
OK well it has been connected all night to Xperia x10 running barnacle no issues downloading through swarm bittorrent client.
Battery was 78% now at 58% so I would see this as acceptable.
Only 1 issue I have noticed, every time you connect to ad hoc it asks for password and adds it as new connection, so you end up with a few in the list but hold on old connections and 'forget' works fine

woooo! Wonderful!
I had used the ad hoc wifi and knew that issue already. Anyway, thank you for remining!!
Maybe something should do with the usage of battery, because there is 20% drop during the whole night.........
well, in that case, my cellphone cannot tolerate it
just installed the JuiceDefender app on my 10.1v.
before that, the wifi/3G standby overnight will consume about 10% of battery.
after installing it, and the night more, it went down by 4%.
2nd day of using it and battery life SEEMS better.
I created a zip flashabile on recovery, we'll post it and put it in the first thread?
Anyone try this on 10.1?

I haven't tried but it works
I cant seem to get it working right...
After following these steps my wifi drops every 10 seconds... It will see the adhoc though ;-D
I have to disable wifi and re-enable then it will auto join a network for another 10sec before it drops. any advice?
I used adb and it worked "MAKE SURE THAT YOU LOCK THE PERMISSION with CHMOD 755 or it will not work"
put the tablet in airplane mode
I download the file put into C:\ of desk top
I had backup my original by using adb pull /system/bin/wpa_supplicant

Tried the flashable zip using cwm 4.0.0.4 but I keep getting installation not successful message. The installation starts, file is opened but the result is unsuccessful. Any suggestions?
10.1v /unlocked / rooted / cwm 4.0.0.4
Edit: Just saw the manual push method above. It will just be so much easier if the flashable version would work.
pushed to system/bin w/ root explorer and edited permissions with RE too.
works so far on my 10.1 retail rooted

Works perfectly. The only thing different is the file size reported. Typo?

I have exactly the same issue. I did this same procedure on my galaxy tab (the original 7" one) and it worked great. Replacing the wpa_supplicant file on my galaxy tab 10.1 has the connections work for 10 seconds and then drop. Incidently, I find this is true for all connections (ad-hoc and regular). Switching back to the original file fixes this. I've played around with the config file in /data/mis/wifi/wpa_supplicant.conf and added ap_scan=1, but I've had no luck. I have the 16 GB retail version. My version also had a locked bootloader. Any suggestions would be most appreciated.
Thanks,
Ben
I don't seem to have this problem of wi-fi disconnecting on my 10.1v. So far working perfectly with Connectify, even when the device has screen off, connection seems to persist - I did select never switch to mobile data from settings. I don't know how long it will stay connected though, haven't done a time test yet.

My tablet is wifi only. Perhaps this is the issue. Has anyone gotten this to work who has a wifi only tablet (retail edition)?
does not work...
Left the tablet aside for an hour. I unlocked the screen, and instantly opened the web browser. The connection was working. So maybe it does have something to do with 3G connection even though it is turned off. I am using Connectify (free version) on my notebook.
Just thought of something. I have juicedefender set to turn off 3g when my phones screen turns off. This could cut connectivity without dropping wifi signal. Will test theory tomorrow...

/sdcard partition read only

My internal SD partition won't let me add or delete any contents on it. Anyone have a solution?
Could you please type "mount" in the terminal and copy it here?
It should be RW, you can try typing in the terminal: mount -o remount,rw /sdcard
Never mind. Got it working by rebooting to recovery, going through ADB, and chmod 777.

Yes, I saw last nigh I was able to see your mount dump. You moved your /data and /sdcard partitions to f2fs. I have been trying to reproduce your issue and I have found the origin of it. It seems that you performed the backup of your internal sdcard using adb when switching to f2fs. In such case you indeed need chmod -R 777 /sdcard
I will update the guide accordingly.
Thanks for bringing this issue up.

It's not that I'm afraid of bricking a phone, it's that I want to keep it usable. That's probably why I won't ever buy another HTC phone until they get rid of CID and MID. And I was one of the guys who cracked the location of the ringtones/notifications on the original Galaxy Gear when it went to Tizen.
Anyway, I let it sit for 12 hours and, sure enough, the chmod fix stuck.

Your sdcard dump was very useful. At least I was able to see it before you deleted it. It led me to the origin of this issue. We are lucky with the 2017U, it doesn't have the DFU mode of the 2017G. Ours at least is unbrickable due to the EDL mode. When doing testing or trying new things, a safe backup is all you need.

V20 keeps voice-announcing "Roaming"

Hi,
I'm using a VS995 with Weta ROM. My phone keeps making a voice announcement of "roaming" . I can't find where to turn that off. Does anyone know how to disable these announcements?
Thanks
In case anyone comes across this issue, I found a file at /system/media/audio/eri/Roaming.wav
I did the following, from Android terminal emulator
su
#You should get a prompt from root manager to let the shell be root
mount -o rw,remount /system
cd /system/media/audio/eri
mv Roaming.wav Roaming.wav.sav
mount -o ro,remount /system
#This command will reboot your phone. It's Probably not needed.
reboot
It seems to have solved the issue, with no untoward effects, but wait for some of the more knowledgeable people on here to reply before doing this, in case this is a bad idea. I remember doing similar to kill the camera sound on earlier Adroidia, without harm, but ya never know.
