Default 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

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?

Default 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.

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.
