Clock [Q] Downgraded to .534 to Root... Please Help

I bought a c6903 from Negri Electronics and used it on AT&T.
I started off at .257 and system updated to .290. fastfoward a couple weeks and I want to root
So I had to go back to .534, when I went to download a tft, they did not have my exact model, so I used the british version.
Installed fine and everything, but when the phone booted there was no signal.(IMEI turned to 00000000... crap) I figured i would root and just flash a rom from there. I rooted with vroot and got a very funky chinese superuser. When I try to backup my TA partition it says it couldnt get root, but root checker gets root, it shows a prompt. I tried installing superuser from the play store. Is there a way i can just get back to .290 for my model, or what should I do help is really needed so thank you.
I want to end up at cm11
to sum it up, I restored to .534 (british version, no signal, no imei) , rooted with vroot (annoying root computer wont recognize the root, I have debugging enabled), didnt unlock bootloader or anything like that yet.
Thanks for helping i just need my phone to have signal at least.

Use for rooting this link: http://forum.xda-developers.com/show....php?t=1886460
Use V33 option 0. When you upgrade to 290 you will get your imei back.If you unlock your bootloader don't forget to make a TA backup for your DRM keys.

You have this issues because you do not read carefully, You can't downgrade directly to .534, first you have to do is to downgrade to .257 and then to .534. Follow the instruction and all will be fine and remember to Backup TA before Unlock Bootloader.
IF I HELPED DO NOT SAY THANKS, CLICK IT.

If you do this way you are under risk to have IMEI and Signal issue

I don't know about that but to get root you have to be on .534, root with Vroot and then Backup TA and then Update, so what the kernel for, dual recovery? if you update to .290 you will wipe it anyway.

Okay I managed to back up my Ta, but now when I want to unlock the bootloader I need to submit my IMEI, but I have none. Should I take my IMEI from the box or is there another way around this? Btw there is a system update available right away to .257. What should I do? I just want to have service and be on cm11, so if I can just flash cm11 from this version (.534) somehow, that would be the best solution.

If you did a backup of your TA and DRM keys you can do whatever you want now, if you want get you IMEI back you have to update to .290 and then Unlock Bootlader and then follow the installation of the CM11.

OT.

Is the one you got from Negri bootloader unlockable?
Did you check in the settings that the bootloader can be unlocked


IMEI use the one on the box
