[Q] Help? Unlocked bootloader - now no WiFi - Xperia Z Q&A, Help & Troubleshooting

As per title really - unlocked my bootloader this afternoon and it all went fine until the phone restarted.
WiFi won't turn on.
I've tried doing a factory reset again, but no change. What have I done?
I was on stock, rooted 434 FW.

No, wifi wouldn't even turn on - the toggle wouldn't move from the 'Off' position.
I did some digging and although it doesn't seem to have happened with the XZ, it's a regular issue with unlocking bootloaders and is caused by a problem with the kernel.
So, I decided if I was going to have to flash a different kernel I may as well go the whole hog.
Downloaded the RC4 build of CM10.1 and flashed it - and everything's working properly now

[Q] Plane mode bug

Hi everyone.
So, this is my problem:
http://images.orkut.com/orkut/photo...9E7ePr_8Am1T1UHiPgwGpeh7tb_Dn59t24Hsb_ZWU.jpg
My wi-fi is turning on by itself after i manually turn it off. And even when i set plane mode the wi-fi is still on. At first i thought it was impossible and i was dreaming but no. This is really annoying me, my battery won't last a day with my wifi always on.
If anyone could possibly help me with this problem i would really aprecciate it! =(
Oh and i already tried wiping all user data and tried flashing other roms as well. I tried shadowmod and cyanogen too. currently i'm using the froyomod 2.7. All have the same problem. I really don't know what to do.

Do you have any 3rd party power saving apps installed? For example, I have an app called "Network Switcher" installed, that given certain conditions, it turns on or off 3g and wifi. I have it set to turn 3g and wifi off between 11:15pm and 7:15am if the screen is off. (this helps save a ton of battery while I'm sleeping)
Your screenshot doesn't look like a clean stock ROM, so even if you did wipe data, it looks like you installed some stuff. Did you do a complete wipe back to stock, and it's still doing this?
No, i don't use any apps to save battery or manage my networks. And yes, everytime i install or upgrade to a new rom i wipe all data. I haven't tried using the 2.2 stock rom to see if i'd have the problem there too. I'm currently using froyomod, i have always used modified roms and i'd never had this sort of problem before.

So when did it start happening? Did you notice it after you installed something? Or after you flashed your current ROM? Did you have anything installed before that may have been saved to your SD card using apps2sd, and it somehow got "lost", but the setting remained?
If I were you, I would flash the stock 2.2.1 SBF (get it here: http://and-developers.com/sbf:milestone221), and reflash the latest FroyoMOD on top of that. First back up all your app data using TB though, and restore afterwards. That may be your only hope.
I noticed it after i installed Froyomod 2.7, but i don't think it was the rom since nobody else complained about a problem like that. And i haven't installed any different apps than the ones i've always used.
Thank you for the advice! I'll try to flash the SBF file right now, and i will also erase my SD Card, just in case.
I'll let you know after it's done. Thanks again!!
Unfortunately i did everything as i was told and nothing worked, the problem won't go away. Guess i'll have to use the 2.1 stock rom. It's better than having my wi-fi always on. But thanks for the help!! =)

Turns out you're not the only one... see here: http://forum.xda-developers.com/showthread.php?t=1064823
They did not have any solutions that worked for them either though. Sorry.
Yes, a few people had this problem as well, but nobody said if they got to fix it or if it stopped.
The most annoying thing: I went back to 2.1 stock rom because i thought it would stop, when i installed it was ok but after a few hours that i'm using the rom the problem started again.
This really sucks. I will never buy any motorola products no more.
Anyway, thanks for your help. It's really good to have helpful people on this forum.
Turning the airplane mode on will not disable your wifi... only the radio(antena).
The question is: does your radio works normally?
Sent from my Milestone using XDA Premium App
Yes, everything is working normally, only the wifi that won't turn off.
Ok... there are two free apps on the Market that might fiz your problem.
1) Wifi Fixer
2) FXR Wifi fix and Rescue
Try it and let us know.

I had already tried wifi fixer before, didn't work.
Tried FXR and didn't work as well! Honestly i'm giving up.
I will sell this phone as soon as i get the chance and i'm never gonna buy a motorola ever again! -__-'

Dont give up yet... have you tried flashing the GOT 2.2.1?
Try this and flash CM7 over it.

I tried CM7 and had the same problem. I think it might be a hardware problem because i tried everything. :/

Hi, I think the problem is coming from the ROM.
First you should wipe cach/data. I mean factory reset, then download a newly fresh Open Recoveries, and do the flash ROM again and place it into SD card (remember to delete the old one: Nandroid and Open recoveries folders and update.zip file). THIS STEP IS IMPORTANT.
Here is the link of CM7 ROm but very light. it si good for MS than ever:

Below is the google apps package:

I use it and it works well.

That should be the first thing you do now. Flash it back to stock and check if it's working. If so, reflash CM again and you'll see what the problem is.

Looks like we are having the same problem. I'm on 4.3 Commercial and Journalists released by @Androxyde , later in order to use TB, I reflash XZDualRecovery to gain root, then I first encounter serious battery drain, 70% to 8 % when I was on a trip, I don't took notice, later it promptly shut down when no SIM ERROR, shut down when launching camera. In order to fix the problem, I fully wipe the phone, use DISASTER RECOVERY to gain back stock recovery[DoomKernel v19] by @DooMLoRD. I flashed back stock recovery and relock bootloader using Flashtool, I successfully did everything back to 4.2.2 build 2.67, boot back into system though without root, later I notice there is no network signal, i try to launch camera but failed, I tried to charge it to 100% [complete], but instantly it shut off. Later stuck like yours. BootLoop problem. Now I am figuring it wasnt hardware problem. I tried to investigate anything. Inspect battery but Android tell me Battery health is good. So , I figure there is something wrong with kernel, especially chargemon.stock .:silly:

My Z also down now. But it's possible to get into fastboot mode and recovery mode. I drained my battery to 0 and then plug it into PC and it's possible to get into it. Try it out. But result is the same. It's like the kernel fighting back on its own to prevent cross platform launching.
Try flashing stock again.same result.shutdown itself again and again. I dont think its related to chargemon because i already flash stock firmware,as im aware if we flash stock ftf,chargemon will revert back to original right?

Can you get into the bootloader (hold power + volume down)? If so, you'll probably need to reflash the stock recovery before the update will install.
Thanks, after I stopped panicking and calmed down I was able to flash Stock Recovery and then the next reboot caused the standard update to work. Kind of surprised really, still rooted etc.
Right now phone is working but Wi-Fi indicator is not lit, even though it is using the wi-fi.

Well you have the dev edition, they aren't going to take root from you. Don't know what's up with your wifi, though. When I updated I ended up having to restore a backup and updating again because of several extremely strange problems.

Good job taking some initiative. Not as difficult as you thought it'd be right?
the verizon 4.4.2 SBF file is out so any issues anyone is having they can just flash the whole SBF file and be complety stock 4.4.2

[HELP] Kernel Panic

Hey guys, I was running Maximum overdrive v1.0 and beastmode 56.8 kernel (no tweaks) when my phone starts freezing and rebooting. It would happen often and even at times It wouldn't boot completely I would have to remove the battery for It to boot. Then It started to get "kernel panic ulpoad mode" I odin flashed back to stock MM but same issues going on. Any ideas? Or its time for a new phone? Thank you

I was curious cause I never heard of that , and some people said a factory reset solved the problem . However a fresh Odin install is good. Did you wipe system as well as the normal wipes?

Yikes. I didn't even see a ton of info on the subject. I can't imagine there is anything left on the device to cause any issues. Hopefully someone with more knowledge about this sees this post. Note 7 release party Aug 2nd if it comes to that!
same issue i see alot of people with it, its the emmc i confirmed it beause yesterday while i was alseep my emmc decided to give up on life no recovery no download failed to read emmc, the problem is repairing it im not gonna take it to samsung as they will charge almost the price of a new phone i have found a chip for it but it says it has sm n910p/f firmware on it not sure if it would be an issue as i could reflash the tmobile firmware on it.
http://www.aliexpress.com/item/Bran...2630152207.html?spm=2114.40010708.4.13.nPWCQ2
any advice on the chip?
So, what was the final solution?
