Well today i found out after getting tired of this trying to root 4.3 i decided to use a custom rom again.
Guess what happend...
No custom rom works anymore as imei magically dissapears. It only returns if you ... guess what...
Use Sony 4.3.
Well thank you very much Sony assholes for updating s1boot and making it irreversibel.
Luckily it seem that it might be able to get fixed with new proprietary blobs but that will maybe take some time for some dev's to add on their builds.

Are you trying to downgrade with Flashtool?, cause in Xperia Z1 is the same, the IMEI goes to 00000 but when you downgrade to 4.2.2 exclude the baseband and everything is ok and then you can flash your custom rom.......

Oh god thanks :good:
i had this experience: i have the 6802, and i was on the stock 4.3 update, flashed the adv. stock kernel to get recovery, and restored a CM10.2 nandroid. when it booted up i had no radio signal, so i restored everything from a .257 FTF except system and kernel, and after that everything was fine. i don't know if this was 'correct', but it worked. i didn't check to see if i lost IMEI, but i definitely have it after doing those steps.

I simply did a nandroid restore with the CWM recovery from the CM 10.2 boot.img - all up and running, IMEI still there.

Yes, flashing .257 FTF fixed it for me too (C6802). I flashed everything.

ah hey, cool. yeah, i would'a flashed everything but i wanted to stay on CM10.2. so i just made sure the other firmware was downgraded.
but again, it seems possible that there cold be other differences between the 6802 and the others? i dunno, but some people seem to be saying to use the baseband from .290 even if you downgrade back to .257?

In my case, I wanted to go back to stock. That's why I flashed everything About the baseband, I don't know cause I didn't note down the version before I flashed .290 so I have nothing to compare to. The one major difference of C6802 from other models is that we can flash ROMs without needing fastboot 'cause kernels are somehow allowed to be flashed from recovery.
please edit the original post title to reflect there's no problem
thanks
so im on 4.3 unrooted

Ya thts right.Plus you have to unlock the bootloader too if u havnt yet.
Hrm... You know, for the life of me, every time I flash from the 4.3 update with Flash Tool, I still lose my IMIE data and thus can't use the mobile connection.

Ok, now i'm really confused.
I'm currently on 757 firmware and I want to flash the GPe on it. What exactly do I have to do?
LordManhattan's thread simply requires me to flash some files but the GPe thread needs me to flash boot.img or something.
Can anyone coach me step by step? I've never tried to flash a darn phone with so many prerequisites... It was so much easier playing with the LG and hTc

From stock 757 with unlocked bootloader:
Copy ROM zip to sdcard of phone
Flash boot.img from the ROM zip using flashtool and fastboot mode. the boot.img will have recovery already in it
Boot the phone into recovery, vol + or - while booting
Factory reset (or format data and wipe caches
Flash the ROM zip from recovery
Reboot into system
I assume you have followed lordmanhattan's guide and have:
Downgraded
Rooted
Backed up TA
Unlocked bootloader
Updated firmware to the latest

So it is okay to directly downgrade from 757?
And what do you mean by updated firmware to the latest?
And the boot.img in the ROM package, does it already contain the recovery?

You want to downgrade to root? if so then yes - see my downgrade sticky thread in the general section for a guide
After rooting/backing up TA/unlocking bootloader you will want to flash the latest firmware again to get the new baseband, and a few other things else any custom 4.3 or 4.4 ROM's won't boot and/or will have IMEI issues

Ok to be honest, im trying to flash that ROM because the recent 757 firmware was supposed to fix the sound bug issue. It worked for others' ZU except for mine. Pretty pissed that all SONY said to me was to bring my phone down for a repair, hence i was hoping i could fix it by flashing another ROM.
I downgraded to .532 then updated it back to 757. Seems like it is a hardware problem...
WOW. I'M AN IDIOT. I DECIDED TO WASH MY PHONE UNDER THE TAP BECAUSE IT WAS A LITTLE DIRTY. AND SOMEHOW, THAT FIXED THE SOUND BUG. SOMEONE PLEASE SLAP ME IN THE FACE.
Close this thread please, I'm an idiot. Thanks blueether for your help!
You don't read very well do you?
All the steps needed were there with an explanation of why (where needed).
Next time you you need/want to flash your ZU take the time to read the steps, and ask questions if you aren't sure about a step or why some said to do something a certain way or to see a certain thread...
ps good to see you have the sound working again

Correct, but only the tweaked version. That's an isolated case though, so the rest of them will have recovery.

Not the same issue ( or at least shouldn't be).
In about phone settings do you have a valid imei no. and baseband?
Have you tried any other ROMs?

Thanks for the response blueether! In the phone settings it says Unknown for both baseband and imei. I found this thread where you helped another person with almost the same problem I guess, (http://forum.xda-developers.com/showthread.php?t=2738141) and you have told him to follow these steps:
"Just do as has been said a thousand times...
Downgrade to .532 - see my downgrade thread
Root using either [NUT]'s dual recovery or bin4ries tool - see thread in step above or LordManhattans guide
Backup the TA - see LordManhattons guide
Upgrade to latest FTF
Unlock bootloader
Root using jackies099's kernel
..."
So I'm downloading a .532 FTF and will try out these steps once the download finishes in a while. As I understand, when I upgrade to the latest FTF (.757 now?) the imei/baseband should return.

IMEI/baseband should be fine if you were on 757 and flashed slim.
You could just try reflashing any 4.4 FTF you have laying around while you wait for the other one to download

Not sure why they vanished. Unfortunately I'm sort of a noob and don't have any FTFs lying around. I read some more threads and now I'm wondering what I should try first?
A - Flash 290 FTF then downgrade to 532
or
B - Straightaway flash 532 FTF
or
C - Flash 757 FTF

"flash 290" was written a long time ago when it was the 'current' firmware. I would flash 757 first and see how that works out.
New firmware is out NJ6. I can't get the OTA yet but it is available from KIES. Hopefully this will solve all of my signal issues.
I saw this on sammobile as well...most likely this will close the current root loophole...will wait patiently until an awesome developer can create a rooted 4.4.4 rom.
Yes, I did lose root but that is okay with me if it helps my signal. Haven't been able to test it in problem areas yet.

I actually have 4.4.4 rooted right now on my device but safestrap doesn't work properly now. It starts to load but then reboots into OS.
The first 4.4.4 rom I made would boot, but only had a black screen (kernel modules didn't match boot.img), then I tried the nj6 boot.img and got the warning about unauthorized kernel. So, I decided to try one more thing. I reflashed the pre-rooted 4.4.4 rom I made and then flashed all of the 4.4.4 firmware in Odin EXCEPT for the system partition. This allowed me to boot into my rooted nj6 4.4.4 rom.

The only way to tell if it will work is to have someone flash just the system when its a flashable zip and then reboot to download and flash kernel via odin

I tried that and it didn't work. The NC4 bootloader won't let you use the NJ6 boot.img. It gives the unauthorized software message.

Hey Guys.
Once i tried to downgrade my Galaxy S6 Edge SM-G925F from Marshmallow to Lollipop with odin, but it failed and i had a brick. I tried different Versions of Odin and with much luck i fixed my Phone. But now i am insecure and hope to get help from you. I installed latest Smart Switch Version. What do i have to do to downgrade without bricking my Device?

Only possible when flashing 5.1.1 custom rom via recovery, but you will lose your imei, BUT you can backup your imei and after flashing new rom restore it.

Yes before you proceed you will need to install a "custom recovery" (Search about it if you dont know what it is)
Go to recovery like you want to format but instead go to "Backup & Restore" and select backup and then select "efs" which is IMEI.
After flashing a custom rom and after the first boot you will notice that there is no signal, so go to recovery and select to restore efs.
I recommend you to backup efs to ext sd card.
This will void your warranty, even downgrading it self will void it.
Goodluck!

Any firmware 4DPG1 or above can not be downgraded. Im guessing before you was on U3DPAD or lower which can be downgraded. The first MM builds could be downgraded. But any 4xxxx can not
ah ok....
then i downgraded fast enough
my main reason of downgrade:
in MM it is not possible to change the font with HiFont App....!!!
i see other people saying that it's possible.
but i have one of the latest builds so, in your opinion , it is impossible for me to downgrade.
but are you sure? i can't believe that, i want absolutely a solution, i am searching it from so many time, please help

What build number are you in? It is impossible to downgrade from a late build 4xxxx. I have tried absolutely everything. The only way is to flash a nandroid backup but even then you will lose imei. You can always back up efs and restore but its not always as straight forward to restore it. You would also need to flash a new bootloader and modem.
Did you make a nandroid backup of your previous firmware? If not then you cant try that.
The only other way you can try is to flash a 5.1.1 custom rom. Again you will lose imei. So efs backup is important. You would also need to flash BL and modem again.
There are roms based on lollipop which is a much safer way to revert back, try one of them.
Overall i wouldnt try it bit its up to you. If you do and you find a way to do it let me know.

You cant downgrade after 4xxxx firmware mate. After updated bootloader your stuck on mm.
There are ROMs based on 5.1.1. But because you flashed 4xxxx firmware you cant downgrade. All lollipop firmwares are 3xxxx

I said the second way was to try to flash a 5.1.1 custom rom. But you would lose imei and theres no guarantee it would work. Its been reported that once you upgrade to 4xxxx firmware its impossible to downgrade
