[Q] Wifi & battery issues on imilka's cm9 - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hi folks,
I can't post in the dev section so I'm hoping someone can answer here instead. Searched imilka's thread but couldn't find anything that helped me. Wipe & reflash has worked for others but not me.
Wifi doesn't work for me. It worked when I activated it in the setup wizard after flashing the rom but after the first reboot it doesn't present me with any networks and it doesn't connect to the one I configured. I know the wifi device works because the mac address is identified in the status menu.
Also, battery time isn't very good. Less than half remains after being fully charged then left alone over night.
I have tried a full wipe & re-flash and also flashed the last version released yesterday. Does anyone have any tips or do I just wait for a new version? Seems weird that it works for everyone else.

Indeed, I didn't come accross any of these problems... I don't know what to say mate, might have something to do from whatever ROM you came from, some kernel remnants...but again, that's just guessing...
What I'd do in a situation like this would be to revert to a stock GB, use jBroid's kernel cleaner, and then try to reflash Chainfire's repack and back to CM. That's just what I'd do...

I'd try to do a factory reset first. That way you'll get another chance to setup your WiFi from scratch and see what transpires. If it fails, it's back to basics, most probably. Rooted GB --> ICS Repack --> CM9.

It's such a hassle to reinstall everything again.
I'm downloading a stock rom now and I'm going to try flashing the modem partition. Perhaps the modem in the chainfire repack I flashed before is not 100% compatible with my phone... Otherwise I'll just have to stick to mobile data.

Flashing modem made no difference so it's something with the ROM. Luckily I have a good data plan so I'll just leave it and see what happens in the versions to come. If anyone has an idea, feel free to let me know.
And thanks for your answers guys.

Suddenly it all works. Thank you Google. You're swell!

[Q] Phone lose all settings on reboot and power

Hi,
Have tried to read up few threads but none seems to have similar problems.
Had install MIUI 2.3.4 for Galaxy S - v1.5.27 rom successfully, running great and etc.
One issue, every time I reboot or power off/on the phone will go back to android welcome screen asking for gmail account set up and lose all settings.
Does anyone have similar experience that have found solution ? Great ROM, would like to keep. But it will be annoying to lose all settings every time I reboot or turn off my phone.
You guys advice would be kindly appreciated.

Hmm, this is pretty bad. You will definitively have to reflash. Did you follow the directions well? Most of these ROMs ask of you to flash a stock firmware before flashing with clockworkmod, so did you? Read up well on the instalation instructions and reflash. If the problem persists, then reflash another ROM.

Try some troubleshooting first.
Reset your Access Point/Router, or try a different router/ap. Flash back to 100% stock and do a "master clear".
I also find it useful to clear out the /efs partition after returning to Samsung ROMs after using CyanogenMod. Of course ONLY do this after you have a tested and safely stored a backup of your current "nv_data.bin" file. You have been warned.
Take out your battery and just let your phone chill for a few hours. That sometimes helps too.
Anyway, if after a complete flash to stock and master clear, and some troubleshooting with different access points you still get no WiFi signal, something may be wrong with your hardware...
From there you might either need to send it into a Samsung service center, or find a very technically minded XDA member to help you further. Good luck!

[Q] Problem with Slim ICS 3.5

Hi guys,
i have been using Krarvind's Slim ICS 3.5 for about 10 days and I absolutely loved it. I have just updated to 3.6 which caused my phone to bootloop
So, after an hour or so of labouring and trying to work my way back in to it i'm now back on 3.5, but I have absolutely no signal/3G coverage. Wi-Fi works no problems, just no signal!
I went in to the APNs and there is nothing there - I tried to save a new APN and it wont let me - has anyone encountered this before?
Thanks in advance
Haven't experienced this myself but a few things come to mind...
First would be to check if you imei number correct? If not you would need to restore this from a backup.
If IMEI number appears correct then I would try flashing the modem again or a different modem. Modems found here: http://forum.xda-developers.com/showthread.php?t=1158783
If this doesn't work you can try flashing 3.5 base and essentials again.
If that doesn't work search the threads and google or hope someone else can give you an answer. If you don't find any help then as a last resort you can flash a stock rom with Odin although I'm sure there must be an easier way.

I've had a similar problem, the updating to 3.6 just went wrong. No bootloop but loads of FC.
My solution has been going back to recovery, do a full wipe (wipe data/restore factory settings) and install 3.6 again. Everything seems to work now but I have to re-install and configure all my apps... :-(
Hope it helps...
Check in About > Phone
Under baseband does it say UNKNOWN ?
this happened to me once, need to reflash the modem. No need for wipes etc

[Q] HP touchpad wifi not turn on Cm11

Hi all,
I recently flashed the cm-11-20140913-SNAPSHOT-jcsullins-tenderloin on my HP TP first time after WEBOS and love to have android on my TP. Although it was working perfectly regarding all aspects, but two days back wifi stops working suddenly and it doesn't turn on. When i slide the bar of wifi from OFF - ON it didn't move and the screen says WIFI TURNING ON and remains. After that i completely wiped all the data and flashed another version of CM11, it did work for some minutes and again the same problem with wifi. I then tried (After Wipping again) the old CM10.1 version with supported files but again it doesn't on from the start. One thing i want to mention that when i change the CM11 version it stops working after couple of minutes and then i shut down and check in the morning it was again working and then again stop after rebooting. I also tried to control it from WIFI Apps i.e. wifi control, wifi manager when it works for some minutes but the apps also failed to TURN ON THE WIFI when it fails from the system.
I also try to search this topic but i didnt find any which worked for me.
Any help regarding this issue would be highly appreciated.
Regards
No any Response:S
First of all, how did you "flash" the ROM? Are you using tptoolbox?
Also, there are several newer versions of jcsullins ROM available to install.
What gapps did you use?
Please provide more information on your part so folks are able to help you.

I have this same issue, wifi works fine on lollipop, but not on cm11, i originally used tp toolbox to remove webos, resize partitions and flash lollipop. I tried going to cm11 for full functionality and wifi would not work, i tried 3 different cm11 based roms and none worked, i went back to lollipop and wifi worked right away.

[Q] "Not registered on network" error. *PLEASE HELP*

Yesterday, my phone just decided it didn't want to be connected to a network anymore. I was running DynamicKat ROM. It just happened out of nowhere and continues today. I've tried flashing different ROMS and they install fine, but I still can't register to a network. I believe I need to update the modem, but I'm not sure. I'm currently on baseband version ANK4, but I think I need to update to BOC4. Does this sound correct? Any advice would be great, and if you might point me in the direction of any files needed it would be greatly appreciated as well. No need to link, but just a general section where I could find the files would be helpful as I seem to have little luck with the search function here. Thank you in advance.
EDIT: Ehhh... Nevermind. It just started working again. I can't explain it. Suddenly I was connected again.
Always a good idea to check your APN settings if you are in a known coverage area with a new ROM. Been my problem 90 percent of the time

Funny you mention this as I run the same ROM and have had this occur to me whilst traveling around my area and in and out of T-Mobile "Dead Spots" which seem to be many...
Even called T-Mobile to report and best they could tell me is go into "More Networks-Mobile Networks-Network operators" and select - Select automatically.
A real PITA when you driving down the road and need to call out or re-connect your call with someone.
Note: I've had numerous issues on different ROMS similar to this so I pretty much blame T-Mobile and their service in my area unless someone else can chime in, I would be curious...

I had a similar problem on DK, except that it was unmounting my sim card completely & I had to reboot to get it working again. Happened every hour or so, very frustrating. I tried a different rom & the issue went away, so it's definitely something funky with DK which makes me sad cause that's my favorite rom.
I just reflashed it last night though & I took the precaution of completely reflashing ANK4 through Odin and redoing root & TWRP too, then flashing DK like normal. So far, so good(and it seems to have fixed the battery life issues I was having as well, yay), so you might try that method & see if it helps for you too. But be sure to back up your internal storage first cause odin WILL wipe it. Learned this the hard way, bye-bye all my pictures & titanium backups :/
Files I used can be found here.. BOC4 is for LP, so you should be fine with ANK4.
