Hi!
Some users (like me) are experiencing BT activation problems with CF-Root kernel on stock xxjvp and xxjvq roms.
Some discussion is happening at http://forum.xda-developers.com/showthread.php?t=788108#. Unfortunately, I cannot post there because I am a newbie and that is a developers thread.
My millage:
* Stock XXJVP + CF-Root + Default Tweaks. BT activation did not work sometimes. Sometimes it worked after a reboot, sometimes it did not.
* Stock XXJVQ + CF-Root + No Tweaks. BT worked at the beginning. No Tweaks looked like a solution like mentioned in the above thread.
* Stock XXJVQ + CF-Root + No Tweaks + ext4.
* Stock XXJVQ + CF-Root + Default Tweaks + ext4.
BT not working. I put wifi off. After a reboot, BT is working again but only if BT is activated before activating wifi for the first time. Afterwords, Wifi and BT can be set on/off without problem.
Conclusions:
* CF-Root may break/interfere with BT activation.
* Disabling all tweaks is no a final solution. May be it is not relevant.
* Disabling wifi before a reboot may be a solution. Needs more test by other users.
* It seems the problem happens when wifi is activated before BT after a reboot.
Please, report you millage.
Hey I have the same problem the bluetooth has a mind of its own it works sometimes and then stops working! Sometimes the reboot does help, but just tried your suggestion of rebooting with wifi turned off and that did the trivk, but time will tell if it stops working or not.

Disabling wifi before restarts works for me.

I experienced the same for XXJVO, XXJVP, and XXJVQ. It clearly seems to be a problem of the CF-Root kernel and maybe the tweaks.
Has anyone contacted the guy releasing CF-Root to investigate this problem?
I did some searching in the CF-Root thread.
There seem to be two possible solutions:
1. After reboot: always turn on BT once before turning on Wifi
2. Disable kernel scheduler in tweaks app
That worked for me.
Same problema here, bluetooth activation not works for me.
A posible fix could be in next CF-Root version:
http://forum.xda-developers.com/showpost.php?p=16103016&postcount=2561
so this issue is common, but does not necessarily affect all users that applied this method of rooting?
the same thing to me, but with the Juwe's Smart Edition 5.0 (XXJVP), and the same solution, just turn the BT first after a reboot. I tryed the last version of Juwe's Smart Edition 5.2 (XXJVQ) and doesn't have a problem with BT... but i came back to J.S.E 5.0.... both have the Semaphore kernel.
I used to use CF-Root and i didn't have problems with BT on early versions.

After i flashed HCDR.Kernel v4.1, the connection drop randomly when my wildfire try connect to Win7 Access Point(Connectify).
However, issue seems to be gone if i revert back to HCDR.Kernel V3.
I wonder if anyone facing same problem. Is there a way to fix this with V4.1 kernel?
Try v4.2. Although that has the issue of the clock speeds being set at 19 - 768 by default. But, if it boots for you, you can use SetCPU or something to change the clock speeds back to normal.
4.2 changed the Wi Fi Driver over 4.1, so, it should fix the issue.
If it still doesn't, some member modified the kernel so that it is stable and with the new Wi Fi driver. That thread should be there somewhere in the Wildfire Android Development Forum.
unfortunately, kernel v4.2 won't work on DK custom for wifi. kernel v3 is unstable even it booted, wildfire reboot occasionally even if cpu set at 518max.
I found the mod kernel with fixing wifi sleep (http://forum.xda-developers.com/showthread.php?t=967746). Yet no luck. Reverting back to original kernel atm.
seems like it is the compatible problem with my connectify host on wifi N mode.
It works fine after it flashed the homemade kernel from HCDR source with N mode disable.
Another issue is the connection drop, should be due wifi sleep issue. It goes away after i use wifi fixer.
As the thread suggests, after resetting & switching to nighty #106 those things that weren't working now are.
Before this the
+GPS didnt work (that was fixed by latest radio flash though not rom)
+Bluetooth didnt work (no discovery tection by either device)
+Usb Tethering didntwork (would enable then disable immediately)
as for wifi, i think it worked b4 too.
hello all,
i have updated to 2.3.4 jvp from js3 telenor
all is fine, battery usage is much much better, no laggs, and no FC/FR..
i have turned on the bluetooth once set the name, and turned it off....
after i rooted and brought backups back,i cant use BT anymore. it just stands and turning on for a min or two, and than goes to TURNED OFF state...
update on the issue: i have recently de-odexed the phone, and the BT worked fine again for the first 3-4 initializations and than it hangs again in the way described above.
any help? any ideas?
i'm willing to try loading a custom modem or kernel to the phone to see if it helps, but as im new to this and didnt quite find the info im looking for. browsing for hours, (and i did ask in some threads to no avail.)
Will loading a custom modem/kernel wipe my data?
is there a solution perhaps?
ty again in advance
Edit: sorry wrong post
You're probably using a custum kernel.
Revert to stock kernel and BT will work
Or you can try my modified stock kernel where BT works fine
i think it is a custom kernel, as it came with CWM. Could it be the CWM thats causing this ?
is ur modified stock kernel rooted?
i would hate to loose cwm backup functions , can it be installed after?
and most important question: Will loading a custom modem/kernel wipe my data?
EDIT: just saw this in CWM
Current Kernel: CF-Root 3.7
There have been problems with CF-Root kernel and Bluetooth. I had the exact same thing.
Take a look at the CF-Root thread
Hi guys,
I've been stuck with this problem for a month. PLEASE HELP otherwise I have to get rid of the phone...:crying:
I was on IMPERIUM 10 with XPOSED Framework active. One day it asked for an update of one of the standard module (I cant remember which one). After the process completed, I wasnt able anymore to use Wifi and BT. Even after reverting the module to the previous version or disabling XPOSED. Sometimes I could use WiFi and BT after a reset for a while, but again they turned off.
I've tried to reinstall IMPERIUM with full wipe, other SAMSUNG ROMs with XPOSED and CM11 (w/o XPOSED) but nothing. Besides, I've tried several modems (with ODIN) and NO SUCCESS as well.
Do you have any suggestion PLEASE?
Hi. After trying a couple of custom roms, I wanted to go back to a stock rom via Odin. I actually succeeded. The phone boots, and android setup screen comes. But in the "wifi connection" screen, when I touch the button to turn the wifi on, it just refuses to turn on. It goes back to off position. I have tried several different country's stock roms (4.4.2 only, I haven't tried 5.0) and they all ended up the same. I just can not turn wifi on in stock rom. Wifi works in custom roms that I installed using TWRP.
Any idea why this happens?
By the way, I also tried flashing different modems, but the result is the same. I read that turning off the phone and removing the battery helps, however, in my case, it didn't.
Any help is greatly appreciated.
EDIT: As I have looked into the issue, some people claim that a custom kernel usually solves wifi problems. I haven't tried it yet but I will as soon as I can get my hands on the phone. Also in another post, I have seen a build.prop tweak "ro.securestorage.support=false" which is claimed to have solved the wifi issues. I am writing these to be of help to others that might encounter the same problem. I will update the post after trying these ideas.
EDIT 2: It turns out, when you flash a stock rom, Odin can't actually flash the modem partition. It seems like it does but it actually fails. You have to do it twice.
No Wifi
Hi,
have some trouble with my Galaxy S4 (GT-I9505). Since 2 weeks I'm trying to get wifi working. 2 weeks ago I decided to root the phone (everything complete stock Android 5.0.1). At this moment wifi was working well..
I did:
- Flash TWRP with Odin
- Flash magisk 18.1
--> booted phone..
Everything seemed to work well..expect wifi. It wouldn't turn on. When trying to activate the WiFi button by sliding to the right it stays grey and after 10 sec. the slider goes to the right side again.
What I've done:
Downloaded several stock firmwares from sammobile --> no wifi
Flashed serveral custome rom's (lineage 14.1, 15.1), android 5.0 and 4.4 based --> no wifi
Tried differnt kernels --> no wifi
Flashed different bootloaders and modems--> no wifi.
Tried to delete files in /wifi folder suggested here in forum --> no wifi
Tried to modify buil.prob set the security value to false suggested here in forum --> no wifi
I don't think thats a damage on the hardware. It must be a software issue?
Bluetooth and mobile data are working well. GPS and wifi seem to be broken.
After spedning weeks of flashinng, recovering etc.. I am frustrated and don't know what to do.
Any advices?
My wifi is not being enabled with this rom. Does anyone know how to solve?
