[Q] No WiFi after bootloader unlock - Xperia SP Q&A, Help & Troubleshooting

Hey everyone,
I'm new to Sony Ericsson phones, and I just unlocked my SP's bootloader today.
What's weird is that after the bootloader unlock, WiFi refuses to turn on. Completely.
On top of that, superuser no longer seems to be working, and because of that I can no longer restore any of my apps through Helium.
I've tried flashing a new kernel, to no avail.
Any ideas?
Edit: Thread closed because no solution for a long time.

[Q] Wifi not working properly

Today I tried the DoomLords method of rooting .244. After I downgraded the kernel to .423 suddenly my wifi stopped working (I wasn't able to turn it on - was turning off all the time). But hey I continued in rooting and after I rolled the .244 back I face another strange behavior of my wifi. Now I am able to turn on wifi, I am able to see packets flowing at the wifi notification icon but I am not able to load any page at all. And yes the wifi actually provides the Internet (my laptop confirms). Anyone facing similar behavior?
P.S.: I bought my Xperia in Japan if it somehow matters.
Edit: After reboot wifi always turn on itself.
I had the same problem, solved by flashing kernel from where I started.
What do you mean by kernel you started from? Original .244 from update or .244 from DoomLord? The original .244 would make me lose root permissions wouldn't it?
Original. 244, no you won't lose your root.

dead NFC and rear led on all roms

hey,
I had 4.2.2 in my 5503. Couple days ago I decided to upgrade it to 4.3 using flashtool, because there wasn't official 4.3 for my region yet . After that, I noticed my led and NFC are dead. Led isn't working (no flash when making pics, not working as a flashight). NFC unchecks just after when I click on it. Tried: downgrade, delete/rename usf (like in xperia z), many others official roms. tried fix and upgrade by SUS and SPCC. No changes. Also tried CM11 4.4, but still led is dead, NFC option can't be even marked. Now I'm on rooted 4.3. Any ideas how to bring them back? And no, backup doesn't exist
waw that's not cool.. do you erase the whole system when you flash?

Yes. I thought it is better to have clean instal. Habit of installing roms on old phone. Everything else seems to work fine. I'm out of ideas.
hmm it's weird dude. well I suggest :
ensure that you bootloader is locked
do a fresh full flash with all wipes
do a reset in settings > backup & reset
then go into service menu > service tests > flash led
for the service menu, at the stock dialer, type : *#*#7378423#*#*
if it still doesn't work after this, I'm afraid this is hardware related.

Did that many times. To have clear conscience I connected phone to another usb. formated, flashed .67 with wipes. After reset, in service menu led is still dead. connected to pc, updated with SUS to .569. and same story. I'm sure they were working before 1st flash and upgrade. If this is hardware problem, should NFC unchecks itself just after I click on it?
Ehh I suppose, I have to deal with it. There is no cure for my zr
ps. in /system/app/ I can see ncf.apk & nfc.odex only. That's it, right?
well I don't know mate, did you ever unlocked the BL? It may be drm related also

NFC firmware needs update?
I got my ZR a few weeks ago, it came with 4.1.2 on it.
Straight away I hooked it up to PC companion and it updated to 4.2.2, during the first reboot I got a message on the screen for quite a while: "Updating NFC firmware"
I then had problems and thought it was due to 4.2.2, I downloaded & flashed a 4.1.2 ROM, once again, on the first reboot I got the "Updating NFC firmware" message.
Then I realized that the problems weren't due to 4.1.2 and flashed 4.2.2 again, once again got the "Updating NFC firmware" message.
This might not be much use to you but it seems to me that the NFC firmware needs to match the version of Android you're running.
Sorry, no idea how to update it manually, just thought it's something you might like to investigate.
Maybe start here ....

Ilko, yes. BL was unlocked. I had thought, drm can be involved with it. If yes, I'm pretty ***. I don't see any other explanation. many official roms. repairs by sus and companion. checked in buildprop editor, and everything looks ok.
alan573819, when I bought mine it was 4.1.2 also. Couple weeks later upgrated it to 4.2.2. but I don't remember that NFC dialog. I just don't remember, so it doesn't mean I never had it it was long time ago. I know that topic. Believe me, I know them all I'm silent reader xda since se k800i. Always found answers without asking. Until now.. I had to register, because no1 have same problem. with z, there is problem only with NFC (no1 complains about led), and they can fix it by deleting usf. It doesn't work for me. anyway, on 4.2.2 I had no problems with NFC or led. everything worked perfect until I decided to upgrade it to 4.3 with flashtool.
my phone was unlocked, rooted, had .310, .67, .569 for at least 3 different regions, had CM11 4.4, was repaired and upgraded by SUS and Companion. No changes. It just has to have something with drm, because I don't believe that hardware was broken during update. drm can explain it. but.. that's weird if NFC and especially led has something to do with it.
okay, then did your ever relocked it? backed up TA? restored it?
Made in ZR
yes, I have relocked zr.
Like I said before, I didn't make any backups. Didn't expect any problems so I just wiped and flashed my phone. On the other hand- who expects them? . I can risk with my own phone. If I do something for others, I always do backups, double checks etc.

NFC not working on any ROM after root

Hi guys. I am dealing with some serious problems with this Xperia Z1.
First of all my friend gave me the Z1 of some dude. That guy was modifying it - rooting, bootloader and everything - and said that NFC just stopped working. He tried so many roms and different configurations and nothing worked.
Finally he just ended up with returning to stock. And NFC still didn't work.
Then I gave it a try. Same procedure - root, unlock, custom recovery, custom roms, kernels etc.
Nothing.
I've read about renaming the usf folder to usf1 to get the NFC to work.
Nope. Phone just creates his own usf folder after reboot. I deleted that folder multiple times and it always comes back.
Finally I got to a point where I must force shutdown the phone because it just won't shutdown on its own or reboot.
Wifi stopped working on KitKat - on Lollipop the switch just hangs for about 30 seconds and then turns on.
What is also interresting I can't enter the Configuration option in service menu because it hangs and force closes.
Model is Xperia Z1 6902
Help me, please. I have no idea what to do.
Hi,
Seems something is wrong with the device wireless. Since neither the WiFi, nor the NFC is working, my S4 already showed a similar problem and was solved flashing another modem, have you tried flashing another baseband on your Xperia Z1?
All the best,

It turned out that I was flashing firmwares for a wrong model. It's not 6902 but 6903...
Fortunately I got rid of all the problems except the NFC ofcourse.
Any ideas?

Hi,
Can you give me more details about how is the NFC behaving? You press the button and it doesn't turn on? It turns on but it doesn't works? Because since the other wireless features are working I wonder if it's a hardware problem.
All the best,

It's not possible to turn on the switch. But I don't mess with this bullcrap anymore; the guy took back his Z1. Probably it's just a hardware problem. Case closed.

Need assistance - SM-G900A stuck at Samsung logo after stock rom flash

Hey all,
Looking for some assistance here. I apologize in advance for not having specifics on everything, but it's been a couple years since I've needed to do anything with this phone (SM-G900A). I picked it up used a couple years ago and shortly after, I did a NOX unlock and rooted the phone for two reasons - using Titanium Backup and to unlock the WiFi hot spot. I recently noticed that something had happened and my root access wasn't working correctly- guessing from one of the OTA updates that was attempting to occur on my phone. I say attempt, because I don't believe they ever successfully installed since they always seemed to error out. I'm currently on StraightTalk, not an AT&T customer. Something weird was up with it though, because I could never uninstall the Xposed Framework or app, yet Pokémon Go was recognizing it was rooted and blocking my access. I should also mention that I had towelroot running on the phone and it's showing the custom unlocked padlock on startup.
Fast forward to last night- I wanted to return it back to the stock ROM so I did my research, found a couple different tutorials that included the correct ROMs and applied one - G900AUCU1ANCE_G900AATT1ANCE_ATT.zip. After flashing, the phone will not boot and freezes halfway through the swirls around the Samsung logo, then goes blank. The blue notification light also stays lit on the phone.
Thinking it was most likely bootloader related, I found another ROM that included separate AP, BL, CSC files. I attempted to flash the bootloader, which failed and I got the following error on the phone - SW REV CHECK FAIL : [aboot]Fused 2 > Binary 1
At any rate, it seems like my boot loader somehow got corrupted or isn't compatible with this ROM, but I was hoping some of you experts out there could provide some answers. At this point my phone is dead, so I'm hoping I can get it restored very soon.
Thanks in advance guys!
The issue identified in this thread (http://forum.xda-developers.com/galaxy-s5/help/g900a-stuck-samsung-logo-black-screen-d-t3050369) seems very similar to mine as well as what's described on this website- http://www.galaxys5update.com/fix-black-screen-with-pulsating-blue-led-on-galaxy-s5-g900a/
I'm seeing the pulsing blue light as well. How do I find the 4.4.4 OA1 Kernel identified in the first link?

Xperia XZ2 keeps restarting continuously

Hi, My Xperia XZ2 is about three years old and worked perfectly, until yesterday. WIthout any reason it restarted, and before the restart was complete, already restarted again. The only thing I can do is turn it off but when I turn it on, same thing. I used Xperia Companion from my PC to re-install software. That works, but when I remove the phone from PC, the setup-procedure starts, but does not get finished because it restarts again! Any suggestions?
