I have a Verizon Samsung Galaxy S4 and the phone automatically updated to Android 4.4.2 and now I don't have flash player. My phone hasn't been rooted yet. I want to downgrade and prevent OTA updates without my permission. How do I do that?
to downgrade, you can downgrade to nc5 using odin and the tar file for nc5
as far as preventing ota updates, there are some apks you can remove in the stock ROM to do this, but I personally prefer flashing a custom ROM through safestrap

I received an S3 which was locked so I proceeded to root it and unlock it. My question is, should I update to Jellybean OTA ? I don't care about removing root but I want to make sure it remains unlocked.

From what I read you can't update via OTA if you're rooted especially if you have installed custom recoveries. Or have modified some system files like radios. You may still receive OTA message but at some point of the install process it may fail. That is why it's best to stay on stock if you're planning on OTA updates.

In about a week, I'll be gifting a Note 3 to my wifey and mom and I'm planning on rooting their phones. Based on what I've read so far, it seems like there is no way to root MJ4 without setting off the Knox flag, am I right?
Second question is, once I've rooted MJ4, can I still flash future tar updates even with Knox set at 0x1? I know I cant revert/downgrade but I should be able to flash newer updates, right?
Edit: One more question. . Is there a Knox-safe bootloader version people are using when upgrading to just the newest ROM's, kernels, and modems? On the S4, we're using the MF9 bootloader stripped of Knox when upgrading to MJA and MK2.
Quick update. The latest Kingo root app worked just fine on MJ4. Root without setting off Knox.
I recently got a Galaxy Note II and have been flashing ROMs for a while on other phones (RAZR MAXX, GNex, and more)
My Note II is currently on 4.1.2 and I've been reading a lot of threads and I understand I can use CASUAL to root, unlock, and load TWRP which is great!
My question is that I see a lot of threats with 4.3 ROMS so how do I update my Note II to the MJ9 4.3 update and keep TWRP or some custom bootloader so I can flash custom ROMS. From all that I've read, the 4.3 update comes with a new bootloader that's locked and unable to be unlocked currently.
The best info I've come across is this thread - http://forum.xda-developers.com/showpost.php?p=49555505&postcount=6
which is saying to download the Firmware: http://www.androidfilehost.com/?fid=23269279319198557 (toltevzw_mj9_official_firmware.tar.md5.7z) and flash it, that should update me from 4.1.2 to 4.3 while keeping TWRP and root? Or am I missing something in how to get to 4.3 and flash all the newest ROMs?

Most all of the 4.3 based rom threads have a link to a partial firmware update that you need to flash in Odin in order for Wifi to work correctly.
The partial firmware update will not lock your bootloader.

If I were you, I would take these steps:
1. Root and unlock bootloader with Casual's latest.
2. Head to Alliance Rom build 23 and download the mj9 firmware there. (This will not cause you to lose root or lock your bootloader) Install using odin. From there you will be updated to mj9 firmware, but will not be updated to 4.3. You will still be on 4.1.2 until you flash a 4.3 rom via TWRP or CWM.
3. Choose any of the available 4.3 Roms of your liking. Make sure you update your TWRP to the latest via goomanager or another alternate way.

I need a bit of help with this one.
I have a Samsung Galaxy S4 on Verizon, Android 4.4.2 Build VRUFNK4 (I believe this is an intermediate build between the stock VRUFNK1 and Lollipop).
What I'd like to do is root, backup the current build and then revert back if possible to VRUFNK1.
I'm new to rooting a phone so I could use a bit of help and links. I've read many of the posts and tips, but most specifically don't mention my build, which makes me a bit nervous.
Will towelroot work with this ?
Should I use TWRP or Titanium for backup ?
And.........can I find and revert back to the official build VRUFNK1 (4.4.2)
I simply want to get out of this strange build, remove bloatware........ and have some control over not being pestered over OTA updates from Verizon/Samsung.
Possibly, in the future, I'll play around with some custom ROM's.
Any help and opinions would be appreciated.
For what it's worth...................
After digging around on the net for a few days, I found the following. Now, I can't be sure if this works, so consider the implications. If someone else here on XDA can verify it then it might work.
If you have a Verizon Galaxy S4 with the 4.4.2 build of VRUFNK4 this was part one of two updates to Lollipop. Many people like me had been deferring the update and then somehow pushed the wrong button and "wham" got stuck with VRUFNK4., but they were able to stop further installation to Lollipop.
So for people stuck on VRUFNK4 it's pretty much the same as the previous VRUFNK1 except mine seems to eat battery power. AND, from what I know VRUFNK4 is not directly rootable( list below).
i545vrugOC1 5.0.1 Lollipop
i545vrufnk4 4.4.2 (intermediate update to prepare for Lollipop, part one)
i545vrufnk1 4.4.2 Kitkat
i545vrufng6 4.4.2 Kitkat
i545vrufnc5 4.4.2 Kitkat
So, you basically have three choices:
-- Leave it on VRUFNK4 (which is part one of a two part update to Lollipop) and live with the issues.
-- Allow the update all the way to Lollipop and live with Lollipop (and possibly root there)
-- Use the following procedure (yet to be confirmed by someone here at XDA and hopefully help with details)
1. Use Odin 3.09 to flash back to VRUFNC5 (KitKat 4.4.2)
2. If the flash is successful, root with TowelRoot
3. Once rooted on NC5 you should be able to flash whatever build you want, backup and recovery using
Titanium Backup, etc.
Anyone that wants to chime in here, it would be appreciated.
Just thinking.........
Could someone with experience in flashing explain to me why a person can't flash directly to a certain build, in this case,
Android 4.4.2 VRUFNK1 from a newer one (reverting to an earlier build) ??
from what i understand, you should be able to flash anything from NC5 and above via odin with NK4. the Bootloader was changed in lollipop builds OC1 and OF1 so that you can no longer downgrade to older builds from those.
Thanks bangdosa for the info. You seem to be familiar with all this stuff.
So, just to clarify, would it be true that if you're on NK4, you could flash using Odin to NC5 ? And hopefully root.

I was hoping to install a custom rom as well but the way I rooted it last time it soft bricked, I used kingroot
Did you use the desktop or via the app on the phone? The app on the phone plus using SuperSU Me Pro should work. Otherwise, you will have to downgrade back to 4.4.2 NB1 update and root that then update via process mentioned here: http://forum.xda-developers.com/gal...-to-update-to-i337oc3-5-0-1-keeproot-t3075814

Note - there are multiple security updates for 5.0.1 so you should read through that thread.
