There are several ways to fix the wifi bug...
1) Download this app, https://play.google.com/store/apps/details?id=com.shantz.wifikeepalive
Open it, select keep on during sleep if plugged, now the app will close...
Open it again, go to advanced>enable workaround 2>Done>always on...
The app will close, but this time your wifi would be stable...
2) Another method is following THIS FORUM
3) You can also follow THIS FORUM...

I am asking fix for WiFi which is not turning on. It works after restart only !!
Working after a restart is a bug within CM10.... It won't work without applying at least some of the above work-arounds/fixes

Dear friend,
my wifi works without rebooting the device...that bug has now been fixed...i did the following in order to have it fixed.
Read this fully...
1. Download the N.O.P.E by @me4488, from here - i am using version 2.6 800 MHz , you should try which one works for you.
2. Download the WIFI Fix rar by @Alijosekt from here here. Extract those files to a folder and copy that folder to your sd card name it WIFI Fix folder for referencing...
3. Copy apk of Root-explorer.apk to your sd card
3. Flash the Rom as per instructions of @cute_prince, these are:
INSTRUCTIONS FOR FLASHING
a. Do a FULL WIPE first. Full Wipe means format /system, /data, /cache.
b. Now flash ROM and then GAPPS through recovery.
c. After flashing, do NOT reboot phone. Instead POWER OFF the device and boot to bootloader.
e. Extract the boot.img from rom and flash it using fastboot flash boot boot.img command.
Reboot.​
when you reach step e in above instruction do the FOLLOWING. DO NOT EXTRACT the boot.img from the zip file...instead use the one that you have download from @me4488 NOPE post rename it to boot.img and the flash the boot.img...reboot the phone afterwards. After rebooting, DON'T DO ANYTHING esle, just install the root-explorer.apk you copied to sd card and follow the step 3 below
3. turn on the WIFI and reboot.
4. If WIFI is on after reboot, don't turn it off. If WIFI is off, turn it on. When you see that WIFI is connected and transmitting data, open root-explorer. & Don't turn wifi off...
5. Goto /system/etc/wifi and rename wpa_supplicant.conf to wpa_supplicant.conf.bak
6. Go to your sd card and copy the files from WIFI Fix folder (all the three files) to /system/etc/wifi
7. Fix the permission of all three files to 644 (i.e User, Group, Others= Read & User=Write)
8. Now without turning off the wifi, reboot the phone...
When it reboots try switching wifi on and off.... & I hope this solves your problem...This method worked for me...try using different NOPE kernels before you search for any other method...
P.S Neither I nor any other person from xda is responsible for anything you do to you phone...the whole responsibility lies with you and you only.
Make a backup first from your existing ROM that is a standard professional practice
And i thank all persons who have made CM10 available on Golfu and solved its bugs... Special thanks to:
 @me4488 for the NOPE Kernel
 @Alijosekt For wifi files and on/off problem
 @cute_prince for the CM10 Rom
& @Ansanen for the Wifi Fix in CM10 Rom

How to root Xperia TX in recovery mode

I have flashed my xperia TX ROM with CYN 12 ROM and installed Gapps , but mistakenly i forgot to root my phone and install Super SU before that .
Now I can only open Recovery mode TWRP on my phone , and when i am trying to reboot after installation it is asking me to install super SU .
If i select yes , my phone restarts with sony symbol but nothing comes up and if I select do not update , still the same happens .
Kindly assist i am stuck, with no idea what do next , i tried installing apk version of super SU from net and transfer into my phone , but i cant even see the file to install in recovery mode .
My phone was working fine with with CYN 12 before but i was showing very limited space for apps and not allowing me to transfer apps to internal memory .

CM12 doesn't need SuperSu, it's already rooted and has it's own method for granting superuser. Did you try to copy any file to the system partition? Maybe you did and there is a permission error...
Try wiping /data; if that doesn't work, wipe /data and /system and reflash the ROM.

11. How to show messenger chat heads?
- Download app-ops app from playstore, install then reboot, after that search for messenger permission, enable the draw over blabla permission : thanks to Kishan Kumar for the guide

A huge thanks for this Rom was waiting for different ui.
It would be great if u will provide some screen shots
Screenshots
I havent found any fc
Hoping that the sim bug will be fixed soon
I dont mind using the Single SIM as I use it for single sim most of the time. Thank you for sharing it here. I'm downloading it now.
an awesome rom
This is the best rom I have ever used on my Sparkle V. Very smooth ,
but I found a bug - while backing up data on local storage the phone hangs and reboots itself in a minute, but that's not a major issue.:good:
guys, I tried flashing, but failed. ,
- first I tried wipe everything, and then flash. But flash or rom failed, giving sole softlink issue. I tried multiple times, but failed. Finally, fixed issue by having another 4.4.4 rom installed first and then flashing this rom without wiping system
- once flash was successful, I rebooted device, but it keeps looping wihout booting up. OP suggested multiple iterations of (battery remove, goto recovery, wipe dalvik, boot) , but I am in my 7th attempt and device not booting still.
How many times you guys had to wipe dalvik? Very much anxious to test this MIUI rom !

thanks @yadavdharmendar, I am installing from philz, and I avoided installing gaps as well. Still not luck. I get Simlink error.
I am coming from FIUI rom. Not sure if that matters (as anyway I am wiping everything before starting rom flashing).
I was on Fiui too
Then i flash cm11 ,then miui

thanks! But why you installed CM11 first before installing Miui. OP didn't asked for it. Just curious to know!
And where you got CM11 from? From Cyanogenmod download page for "sprout"?

Thanks all. Installed cm11, then installed ROM with the patch, and avoided flashing any gapps. It worked! Just one bootloop, which went away after wiping dalvik.
Thanked OP!!
BTW, any ways to make the navigation buttons look big. And possibly increase bar height?
about 2nd sim
bro plz plz get 2nd sim working.
thanks for your work and you are awesome.
@teztaz--v3
how to make navigation bar transparent ?
and a big thanks for your beautiful awesome work
no FCs seen so far!! Looks perfectly usable as daily rom.
Just one problem seen :
Can not install Google maps. Says insufficient space, which is strange. Also failed to install Link2SD. Tried even installing from ADB, gave error INSTALL_FAILED_UID_CHANGED. Hope Miui is not blocking it.
Every thing is fine bro its super rom but I can't move apps to SD card
Thanks bro! gr8 work! bt can u make e single zip with all fixes? people will get confused with so many patches

Make Viper4Android workable with Stock Kernel of Sprout

I was looking how I can use Viper4Android with my Stock Kernel of Sprout 8. I don’t like custom kernels and Viper4Android was the only reason to use a custom kernel. So I started to make V4A work with stock Kernel. After spending some hours, I have found a way to make it work.
What you need to do is that flash the zip by recovery and then reboot your device.
You can find the zip at the end of this thread.
Once rebooted, open Universal Init.d app ( it will be installed by the zip along with required scripts ) and give it root access.
For root access, you need to open the app and press the " Test " button. After granting the root permissions, enable it by tapping on the " Off/On " button. Reboot your device and all done.
Try at your risk. Tested by me for many times and did not cause any problem.
Ping me on Facebook if you face any problem.
Download V4A enabler.

[Help] A5 (2017) Dual Sim | SM-A520F | Rooted with SuperSu but no full Root Access?

SM-A520F flashed with Russian (SER) 7.0 A520FXXU2BQH4_A520FOXE2BQG7
Rooted with with SuperSU
Steps followed in TWRP:
1. Factory Reset (To start fresh)
2. Flashed no-verity-no-encrypt_ashyx
3. Format data
4. Flashed SR3-SuperSU-v2.82-SR3-20170813133244.zip
5. Reboot
Root checker shows Rooted.
However, it isnt properly rooted , it seems, because:
1. AdAway shows a *SU Binary Could not be found*
2. ES File Explorer 's Root explorer isn't working: *Sorry, test failed* message pops up.
Any idea how to get properly rooted?
EDIT:
More info: It seems the root is working for certain apps like Droidwall which I use to block internet access.
The system is not properly Writable (has read access only) which is causing the issue with some root apps. So, I guess I need a solution to make the System Writable.. Help?
Hi, I have the same problem on Italy ITV Nougat.
The phone seems to be rooted ("Check Root" give sucessfully rooting), but when I try to delete app from "App Remover Root" it doesn't work and the same if I try to uninstall/delete the apk from ADB.
Any idea?
