You can do anything you want, except one thing-change KNOX Status.First, you have to make sure you are root.Then flash a custom recovery.
Once done,you can flash a new custom ROM`s.
I insist it is possible to unlock your phone,flashing modified ROM 4.1.1/not stock/ and using a hidden menu to unlock from this thread:http://forum.xda-developers.com/gal...card-unlock-samsung-galaxy-s3-gt-t2185866,but you must flash a custom ROM 4.1.1 from this thread:http://www.htcmania.com/showthread.php?t=738977 .Naturally you have to flash through custom recovery.
Various of our colleagues from this forum/HTCmania/ have done- applying this method.Good luck

yeah you right

Hello,
You have a procedure for downgrade version 4.3 to 4.1.1
How did you do?
Can you make a tutorial?
I speak little English.
Thanks,

Hello,twedie,here you have the minitutorial you need.I hope help you.
First, you have to root your phone.You choose the method.Then you need make backup EFS -IMEI using this
thread:http://forum.xda-developers.com/gal...warning-guide-backup-restore-imei-nv-t1946915.
Second you need to install a Custom recovery-here:
http://forum.xda-developers.com/gal...covery-i9305-cwm-philz-twrp-versions-t2694249
Third you have to flash through Custom recovery a modificated ROM 4.1.1 from here:http://www.htcmania.com/showthread.php?t=738977.
Fourth-use the debbug menu/hidden menu/ from here:
http://forum.xda-developers.com/gal...card-unlock-samsung-galaxy-s3-gt-t2185866,but
This is all,now you have the SIM card unlocked and when you will,you can return to 4.3 version.Good look.

You mean to eventually pay for the unauthorized unlock & in the mean time be on 442. No problem but one, the Guy who has the codes may not last as long as your warranty!
Nono.. My device is unlockable via motorola site.. I checked that.. But didnt unlock yet

Yes, you can update to 4.4.2... and unlock anytime you wish.

As long as you are sure you can get the unlock code from Moto directly, you can unlock the bootloader when you are ready. Once you do unlock, you can root any version rom that is on your phone.
Just keep in mind, if you want to root & disable write protection BEFORE you are ready to unlock the bootloader, the only options are SlapMyMoto/MotoWpNoMo which do NOT work with Android 4.4.2. (i.e. if you want root without unlocking bootloader, do not upgrade to 4.4.2).

[Q] Problem in rooting 4.4.2

I have an Xperia Z.Recently I flashed it with 4.4.2(still this update is not available in my place .so i downloaded the FTF file and flashed it).I am not very much impressed with the performance :crying: .First the lagging,next the battery drain caused by the google play services .Now I want to root my Z.Doomlord's method(http://forum.xda-developers.com/xperia-z/development/cwm-based-recovery-6-0-4-5-xperia-z-t2167381) requires us to unlock the bootloader.But I don't want to lose my BE2 again(I had previously lost it before 6 months by unlocking the BL).so i decided to backup my TA partition using this method(http://forum.xda-developers.com/showthread.php?t=2292598).But this one also requires root.so plz suggest me an idea to root my device without losing the be2.
Good question you've made, i hope DoomLord will answer fast. I still afraid root my 4.4.2
Only method...
Flash stock. 67 firmware,root it,backup ta,...unlock BL,flash 4.4,follow doom steps

So the BL stays unlocked even after flashing an updated or downgraded version of android???
No need to unlock bootloader.
Just flash stock 67 firmware as mentioned, root it and get dualrecovery for it and then flash stock based 4.4.2 and Supersu fix with recovery, shut phone down from recovery and flash kernel for it. All this info in general and android dev section. I hope you understand what i meant.
Pardon my english.

Just keep stock rom without root, and wait for OTA
Edit: If you want the update and dont wait for OTA just flash 4.4.2 Tmobile version and download the OTA (Tmobile version too).
Then install recovery twrp and root your phone using the twrp.
I did that !!!! Now I've 4.4.3 rooted

If you have root...Im 95% sure that you can't receive/install OTA. I've 2 moto x...... The first one updated via OTA and the second one updated via "manual" OTA. My 2 moto x is unlocked bootloader with no root.
I rooted my 2 moto x after the 4.4.3 update [emoji6] You know........ No risk.

About LG L90 D405n original rom firmware backup

Hello,
I am new in this forum. I was searching, but I didn't exact information about my question.
1) I want to do backup of my LG L90 D405n stock firmware rom. (Can someone give me link of these exact procedures?)
2) If I write and use for some time in my LG L90 for example CyanogenMod, and after some time using that I will restore to original stock firmware. So when it will be restored to original firmware, do I get back warranty?
Regards,
Lukas
You can backup your current rom (any rom) using a custom recovery (cwm or twrp). If you want to recover warranty you need to flash kdz stock firmware.. Hope it give you some help

Thank you. What is kdz?
And why I need to download kdz, if I want to do myself my phone's rom firmware backup???
Can you give me exact procedures how can I restore stock rom with warranty?

If you want to backup your device and experience other custom ROMs, you need to root, unlock bootloader and install a custom recovery on your phone. Just by rooting it you will loose your warranty. If you want to get it back, you will have to flash a kdz file (official LG rom) that will unroot your phone, relock bootloader and remove custom recovery.. You have lots of tutorials to "unlock" phone in l90 thread here at xda (just do a little search) but to ”relock" it I only find this (it works):

Well, I have rooted my phone, but I don't find how to unlock bootloader for lollipop version, because everywhere is attached file "L90_D405n_v10b_aboot.zip", not v20a.

The link where you have aboot.IMG for lollipop, (above post) download latest recovery there too.
Make sure ur flashing recovery in the right place.
To flash a custom ROM (my advice cm12.1, Orion lp or uber slim) just follow steps in each opening post.

Grab my dual sim stock firmware version from the TWRP thread and flash it with newflasher v13.
It will wipe/factory reset your userdata.
But that is needed or you will receive a bootloop.
