[Q] NOOB trying to update MK2 firmware to Lollipop

As the Title states I have been trying to flash to Lollipop using the thread Update to lollipop and keep root using Flashfire app. I have downloaded and followed the procedure (yes I am rooted and confirmed with RootBasic) with it failing.
What happens is I load the files in order stated per the guide hit the lightning bolt, does the reboot and then gives error no command and then sits at stock flash update where you can either reboot, flash file or few other choices. I have tried numerous times with each time same result. What is going wrong? As I stated on am on MK2 firmware with ATT update frozen so not sure why this is. When put in download mode I confirm Knox 0 and Offical software with it having 0x30 for bootloader. Any suggestions or should I ODIN update but with what?

We just discovered this morning on the Vz S4 that FF does not function properly on their MK2(4.2) firmware which is likely also the issue here. You will first need to update to KitKat using the following file then root with towel root before updating to 5.0: https://www.androidfilehost.com/?fid=23501681358548937

Before I proceed to KitKat with file linked to is there a guide to properly performing this and then rooting? I will update from MK2 to NB 1 then I need to root, then do the FlashFire and Lollipop undate. I see the guide to use ODIN but then I will have to root I also have not used towel root either so any guide would be awesome. This should not change KNOX either correct (although I guess it does not matter since I am long out of warranty)?
I want to have a clear understanding of procedure so I don't brick the phone! I have not used ODIN before since I haven't really done much rooting other than when I first got the replacement phone last year

I'd suggest [GUIDE]Odin to Stock, Updating, Rooting, and Installing Safestrap by guut13, and of course [How-To] Update to I337_OC3 - 5.0.1 and KeepRoot (4/7/2015) by muniz_ri for rooted Lollipop. Look in the I337 General forum for both.

Thanks Creepyncrawly and muniz_ri for both of your help it was easy to update from MK2 for this noob!
Ok I followed the guide and did update to stock nb1 and rooted, used towel root and then used flashfire to Lollipop and all seems to be working (I still am in process of setting phone up but it is running lollipop).
Since this is oc3 rooted is there anything else I have to do such as freeze att update? Anything else I should do right away?

Galaxy S4- How Do I Update From 4.4.2 To 5.0?

Update from 4.4.2
Hi all,
I'm stuck on 4.4.2 right now, but i want to update to 5.0.
Anyone who can give me a tutorial?
I have no SD card.

Connect to a good wifi, go into settings and there should be an "Software update" option somewhere, if you are on stock rom.

Do this,go to sammobile,download firmware 5.0.1 for your mobile and install with Odin program,that is all .

Yes if can't update from ota, download firmware from sammobile and flash via odin . .

I forgot to mention, that i have rooted my phone using CF-autoroot

It doesnt matter, you can flash your official firmware via Odin whenever you want. Just download the firmware from sammobile.com and flash it. Thats all. In addition if you want to use a custom rom you can choose a 5.x.x version of it and flash it via TWRP recovery. It is your choise.

Okay i've followed THIS tutorial, but now it asks for some root issues.
"Root access possibly lost. Fix?"
"THIS CAN NOT BE UNDONE"
"- No"
"- Yes - fix root (/system/xbin/su)"
I want to keep my root

I am quite stuck untill someone tells me how to keep my root.
I am using CWM.

I337UCUGOC3 bootloader locked, want to update to I337UCUGOK2 to unlock bootloader

I hit on UPDATE on the phone for an OTA update but it only says UNABLE TO CONNECT AT&T SERVER. When I bought it, it had 5.0.1 (I337UCUGOC3) out of the box. Searching on internet says that is bootloader locked (so I cant do anything).
- Can I Update to I337UCUGOK2 and bootloader will be unlocked (I mean, will I be able to do it)?
- Does anyone know where can I grab I337UCUGOK2 for offline install and is it ODIN safe to update it (remember I have I337UCUGOC3 bootloader locked)?
please help

Once the bootloader is locked, it will always be locked until someone finds a way to unlock it. Updating the bootloader will not allow it to be unlocked.

Unlocking/exploiting the bootloader for the AT&T is still in process, I think.
Bootloader locked means you can not install custom recovery like TWRP, CWM or custom kernel. You can still root, you can still use odin and you can still install custom rom using either safestrp or flashfire.
Here is the thread explaining how to upgrade stock or rooted stock roms.
The explanation starts from installation of NB1 firmware so that you can easily root the phone by using twolroot.
If you do not care for the root you can start reading from the step 2 "Flash update in stock recovery"
Since you are on OC3, you need OC3 to OC4 and OC4 to OK2 files to get OK2.

help... I want to RMA it

Everywhere says I need a kitkat rom as base.
My s4 came with 5.0.1 with OC3 and bootloader locked out of the box. I tried some post where says I can flash TWRP and CWM but my phone stucked on bootloops. Then I managed to get back to stock rom and now when I want to turn it on it says " SAMSUNG (and lower on the screen) Custom"
Camera began to fail and I want to return it as RMA but I was looking to reset the flash counter but every post I read is that OC3 bootloader locked users are just doomed.
Do you know a method that I can do for reset that counter?
Camera dont focus anymore and I tried all the posts about safemode, etc.

Flashing TWRP and CWM is for the AT&T S4 with older bootloader (MDL, MDB). After that two firmware versions the bootloader is locked.
For AT&T S4 the last full firmware released is NB1. After that they released incremental updates via OTA. That is why you need kitkat (NB1) as base.
For NB1, Muniz uploaded two firmwares. One is the stock and the other is rootable stock. Try the stock one and see you still have the custom symbol.
To reset the counter, there is an app calls Triangle away by Chainfire. However, it does not work on AT&T S4 with locked bootloader.

Trying Odin-Stock NB1

OTA does nothing, smartswitch shows no updates neither kies.
I'll have to Odin it back to OC3
Can I have some help?

And Success. I'm back on stock OC3 no root.
time to RMA
- camera still doesn't focus
- boot screen is back to normal but when in odin mode the counter shows 0x1

Is there any way for me to root?

I have a g900v with android 6.0.1 I downloaded OTA. I know nothing about this topic, I was an apple user for 4 years then switched to this. I've tried to downgraDE using firmware from sammobile, don't know if that's what I am supposed to do... but nothing ever works, it either gets stuck on verizon screen or Odin says fail and I have to flash 6.0.1. Can anyone help? And remember I'm a noob so if you do help, please post links and stuff.

I have the same question.
I've looked all over XDA and other places and it seems that we have to use safestrap, but that requires root, and root requires an unlocked bootloader, but to unlock your bootloader requires root. I'm finding a circular reference that makes it impossible to do anything!
My CID starts with 15, im on Android 6.0.1 Marshmallow (received OTA), not rooted, bootloader locked, on verizon. Is it possible to root this phone?

Did you guys see the stickies at the top? It's all (all of it) spelled out for you there. Read the guides

Guys, there are 2 guides you HAVE to read. Only the OP should do it.
In general, odin back to official PB1, then root the PB1 .
http://forum.xda-developers.com/verizon-galaxy-s5/general/root-method-og5-ok3-t3290370
Then unlock bootloader and flash to a MM rom.

I have tried to do all of this, but I don't have an unlocked bootloader and every time I flash pb1 it's a soft brick. Any help with this would be appreciated!

Right after flashing pb1, reboot into recovery and do a factory reset.

You mean it will softbrick when you flash pb1 tar file in Odin?

nsol1, read what Lightn1ng has stated and you should be fine. If not, try downloading PB1 from the link here:
https://www.androidfilehost.com/?fid=24438995911970571
When you download it verify the md5 to make sure the file isn't corrupt in any way.
Also make sure you are following the guides EXACTLY as instructed from the link provided earlier in this thread. You must follow the two links in order, the top being the first that allows you to root, and the second link being last that unlocks your bootloader. This is not an easy process going from Marshmallow back to Lollipop, then unlocking bootloader to flash rooted Marshmallow, but take small steps at a time, pay attention to details and instructions and you should be able to do this with no problems. I am actually going to do this later today with a family member's S5. In about 24 hours I will update if I am unable to complete the steps provided. If I am able to get it working, then I will make sure to tell you what steps I took, if it was any different than what I stated in this post.
Research is always a good thing to do before taking the jump. I have already downloaded the necessary files onto my laptop before I proceed, including the files to flash in the event I make a mistake. That way I don't spend half a day downloading everything while the phone is unusable. And I have read through the majority of the comments to see what problems others have had issues with so I know what fixes there are.

Did you uninstall safestrap before you use flashfire?
Do you use the rooted lolli rom mentioned in the guide or the custom lolli rom. If you use custom lolli, is that rom mentioned that it is flashfire compatible?
I understand you are on NC1 bootloader so in order to OC4 working properly, OC4 bootloader need to be flashed via odin.
If you try everything and did not work, go back to NB1 and start from there. Use the NB1 firmware that I mentioned before.

So dude, when I went into download mode, everytime I tried to place that ALLAT&T file into the AP slot, it would cause Odin to freeze and not respond. Naturally, I got angry and decided to reboot into system and magically, I could use the OS again. Now I think I'm going to flash the bootloader like you said

I am sure you did extract the .md5 from the .rar. The latest odin is Version 3.10.7 but I am using version 3.10.6 for that .md5 and it went well too. Try with different odin then.

Wow, NC1 flasher is to use safestrap in lollipop. It only flash the NC1 kernel.
Are you in Kitkat or lollipop. If you were in your lollipop you need to update your lollipop bootloader.
As I said before, if your phone went to softbrick just flash the NB1 firmware via odin.

I swear, you are a legend, an absolute god. The amount of help and experience you have given me, if only I could pay you (I'm 15, so I can't make a PayPal yet) Right now I'm on Albe95's Note 5 port rom.
