[Q] MF3 to NJ4? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Dear all,
first of all thanks again to this great community! there's so much here on xda...
and here my situation. I admit I am a bit rusty with flashing roms for samsung devices. I did root and flash roms for the galaxy S1, the S2 (the phone I loved the most so far) and the S3. But then I jumped to LG G2, then Sony with the Z2 and the Z3.
But my wife has an ATT Samsung Galaxy S4 and I need to catch up with Samsung modding.
I did root her phone 6 months ago. But now I would like to update to KitKat and I am a little lost.
Is there any way to upgrade from rooted 4.2.2 MF3 to 4.4.4 NJ4?
I found this post http://forum.xda-developers.com/showthread.php?t=2717175
but it's for non-rooted MF3.
I do understand that, since I already have root, I need to install the Safestrap Recovery.
http://forum.xda-developers.com/showthread.php?t=2448925
First issue: in the introduction @Hashcode mentions the risk for bootloop if ENCRYPTION is ENABLED. how do I know if that applies to me?
Then, if I succeed and install Safestrap 3.65 and I can access recovery, how do I proceed to install 4.4.4?
In the Safestrap post it is written "IF YOU'RE ON MF3 ONLY USE ROMS BASED ON MF3" so... how do I move forward?
Thanks a lot for the help!!!

If you don't know about encryption, you probably haven't enabled it. The easiest way is to ODIN to NB1 and then root from there. You'll lose your data so make sure to back up anything you want, including backing up your internal storage to another SD card or your computer. You might be able to jump to NB1 with the ROM here but I don't know if it flashes all the bootloader parts you'd need nor do I know if that would keep your data.

Thanks DeadlySin9!
I'm ok with flashing to NB1 with ODIN as I don't need to keep data.
Still few questions:
1. can I just flash with ODIN directly from MF3 to NB1?
2. OK if I flash the second file in this topic (http://forum.xda-developers.com/showthread.php?t=2674223) and then root?
3. this brings me to NB1 4.4.2. with root. How do I jump to NJ4 4.4.4 from there?
Thanks again!!

Ok. I did some further reading. This is what I found out to update from MF3 to NJ4.
1. Flash with Odin NB1 stock
http://forum.xda-developers.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642
2. Take the NJ4 OTA update
3. Flash with Odin NC1 kernel
4. Root using Towelroot
5. Flash with Odin NJ4 kernel
This should leave me with rooted NJ4.
Can anybody confirm I got the steps right?
Thanks again!

correct
Thats correct all the steps are right but if you are interested in having the safestrap recocery you will have to install that first before flashing the NJ4 kernel

Thanks @brownie9987!
I'm not sure I need Safestrap. My goal is to have a clean de-bloated stock 4.4.4 rom. So I plan to root and then uninstall all the samsung bloatware. Do you recommend otherwise?
thanks!

My opinion
Well the only problem I see if you take that route is that once you use towelroot to root youre device and just install flash the nj4 kernel youre still going to have samsung knox on youre device and once you reboot it will remove youre root I personally done all the steps you took but I installed safestrap and installed Goldeneye rom or Goldfinger great roms updated constantly and the best parts its completely stock no added anything no knox and you can choose to uninstall each app (bloatware) under the application manager im running Goldfinger right now and its based off of the samsung galaxy s5 and Goldeneye looks like the S4 it all just depends on what you like but with either one you cant go wrong as long as you follow the install instructions for safestrap users its very detailed

I'm going to read and see which one of the 2 to go with.
And thanks mentioning the Safestrap step. I wasn't considering knox.

DISCLAIMER: Follow these steps as your own risk - read two or three times if you are new and read other threads as well. I will not be responsible if you brick your phone
There was a similar situation for upgrading an i337 on MF3 rooted with saferoot and safestrapped 3.72. Basically following these steps helped get it to NJ4 without ODIN
You'll need:
1. I337UCUFNJ4_100%_Stock_Rooted_ROM.zip thanks @muniz_ri
2. NJ4 Native Tether Addon I337UCUFNJ4_Safestrap_TetherAddOn.zip from here post number 8 thanks @rodin95
1. Download and copy these files to your external SD Card
2. Reboot S4 i337 to recovery after the SD Card with the two files copied to it inserted on to SD Slot of the phone
3. Once on SafeStrap recovery, tap Backup to backup your data/cache to external SD card (make sure that you backup to external storage by tapping on that Storage option)
4. Go back to Home button and do an advanced wipe of system, cache and data and DO NOT Wipe external SD Card
5. Go back to Home Menu, tap on Install, locate and select the file on external SD card tap on I337UCUFNJ4_100%_Stock_Rooted_ROM.zip, swipe the button to confirm install DO NOT REBOOT once install is completed
6. Go back to Home Menu, tap Install again and locate and select the file on external SD card, I337UCUFNJ4_Safestrap_TetherAddOn.zip swipe the button to confirm install
7. Go back to Home Menu, tap Restore and choose the backup you made before from the external SD card
8. Reboot phone. It will take about 2 minutes for initial reboot with AT&T logo - be patient - now you have your phone on NJ4 retaining root and SafeStrap.
9. Optionally install the latest SafeStrap one more time and update SuperSU normally.
Hope it helps someone!

Can anyone confirm these steps?

Your procedure is very easy... Is it possible to go to NJ4 from NB1 through the same procedure?

[Q] AT&T Samsung Galaxy S4 - No System

I know I am stupid, but I am trying to just get this phone to work. I did try and search for something that would come close to what I am encountering, but so far I can't find anything that would suggest a possible workaround. So, I hope this is in line with the rules, if not, please let me know and I will remove this myself pronto.
I was on 4.3 (MK2), rooted with TWRP and installed Xposed, all was fine and well, until AT&T decided to attack my phone to "remind" me to update to a newer version. After a few weeks I finally gave in, and knowing that I have somewhat heavily modified this phone, I went ahead and disable and uninstall Xposed, then head on to try and flash NC1 onto this phone via TWRP 3.72.
I was following this post, using post#3, and all was well, expect when I tried to flash AP using Odin, it was late and I failed to catch the fact Odin didn't connect my phone, so I guess the kernel didn't update. Then I went ahead and try booting it up. It got to the AT&T globe logo, only it has orange strips instead of blue. I waited maybe 15 mins for it to boot, and upon thinking it is not working, I pulled the battery and went into recovery and found I had a very early version backup, which I then restored that. It did boot! But the wifi wouldn't turn on, so I went and checked, the baseband was on NC1, but everything else is at MK2 (4.3). At that point, I give up and went to bed.
This morning, after giving it some good thoughts and research, I tried to Odin again, and this time I succeed, Odin recognizes my phone, and it flash the AP as it should. But when I try boot it up, it would only get to "safestrap disabled" and then black screen. After that, I can only get into the custom recovery, but no matter what I try, full/advance wipe, install, it would show something like "E: cannot mount system" so no matter what ROM I downloaded, it would not install, and when I try and re-boot, it would warn me that there is " No System"
So my question now is: since I can still see and access recovery, not all hope is lost, but since this is a work phone, I do need it back up and running, and I need it fast. How should I proceed from here? I tried straight flash a GPE ROM from here, but it would still run into the error of "E: cannot mount system" and trying to wipe/advance wipe would not work either.
If anyone has any idea what kind of problems I am running into, I am all ears to hear and try my best to get my work phone back up and running. Thank you all for taking you time to read, think and maybe help.

Are you sure you have Safestrap 3.72? It should be working if you do. Either way, try flashing the MK2 AP file/kernel from the downgrade thread or the KitKat Toolkit. That should guarantee it mounts and then you can try again. If that doesn't work, you might just have to ODIN NB1 and start from the downgrade.

I am now just trying to boot up the phone to check, and right now it is stuck at the Samsung Custom lock (white). So I guess either Odin NB1 or MK2 and start from there?
The only thing I think its odd is, it keeps telling me that it can't mount the system, and I can't for the live of me figure why that would even happen....

If you had not taken the OTA from AT&T your phone bootloader is still on MK2.
Did you flash NC1 before or after you received OTA from AT&T.

I was not able to take the OTA from AT&T, due to that it was rooted and Xposed, so somehow the system check would backfire. When I got the phone, it was on MK2, and I only rooted it and installed custom recovery, for I only need to be able to delete some stuff at will, thus, the root access.
Actually, since I can't boot pass the Samsung custom lock, is it still possible to use Odin? I would have thought Odin would not recognize the phone since it is not on.....

It will still work, ODIN requires you to hold one of the volume buttons while powering on to go into download mode on the phone which doesn't require booting to system.

OK, so just tried Odin it using the files from Deadly Venom Kitkat Magic Tool. Odin caught the phone alright, but after the files are lined up (the mk2 ones), it give me the following:
Get PIT for mapping..
There is no PIT partition
All threads completed. (succeed 0/ failed 1)
And of course, the top also showed FAIL!
Any suggestions? Try going directly to NB1 and downgrade from there?

So after an all-night, I finally got it back up and running. Here is what I did, in case someone runs into the same problem.
I grabbed the MK2 file here, un-zip it, Odin it to its respective slots, and then flash it. It took over 10 mins, but it did finish the flash, and Odin showed "PASS!"
So, now I have another question, I booted it up like when it first came in the box, so went through and did all the setup. I went into setting, and I see the following:
Android version: 4.3
Baseband: I337-MK2
Kernel: signed Sat Nov 16 14:33:13 KST 2013
Build #: JSS-MK2
So if I want to do this upgrade to 4.4.2/4.4.3 again, would I consider my phone as stock MK2 that has not been tried to upgrade to 4.4.2/4.4.3? I did try and confirmed that I don't have root (obviously), so I guess I have to treat this phone as if it never took any updates/modifications? Then I would ask which route to follow to ensure the best and most confirm result of upgrading to either 4.4.2/4.4.3.
Thanks all for your thoughts on how to de-bug this. :laugh:

Yes your phone is stock MK2.
I do not know about 4.4.3 but you can find many 4.4.2 custom rom in the developer section.
First you need to root the phone. You can get the required files and instruction from here.
Second, you need to install the custom recovery. Since you are on MK2 you need to use Safestrap version 3.71. You can get the file and instructions here.
Once you have rooted and finish installing the SS (safestrap) you can find the custom rom in the developer section. Find the roms with SS option.

Sway8966, thank you for saving my behind more than once.
I will be following your instruction as to rooting the phone and also install custom recovery. However, if you see my first post, it seems I need to first install SS 3.71 to root, then SS 3.72 to upgrade to NB1/NC1? I will take a safe bet that I can't just use SS 3.72 to avoid brick. Also, that GPE version ROM, I had trouble finding the kernel, would there be a place to find it? Or is it in the package? I un-zipped it, but can't find the file that looks like the kernel in it.
Thanks again. :laugh:

iantung329 I am glad to help you out.
You do not need to install SS recovery first to root the phone. Rooting is done by using the adb command to push the super user in the system area.
Since you are in a MK2 firmware/bootloader Safestrap 3.71 is the only one you can use.
Also your bootloader is MK2 so I would not go to install the NB1/NC1 system file on your phone. SS 3.72 is for the NB1/NC1.
To upgrade your phone to 4.4.2 OS you can find the custom rom packages (including the kernel) in here.
Bootloader MK2 and above can not use the custom kernel since there is no exploit for the kernel out so far. So you need to choose the TOUCHWIZ rom with SS version, not AOSP (Android open-source project) rom.
We are not supposed to tell you which rom to choose because people might not have similar taste or expectation in the choice of rom. Read around and choose the rom that you want.
If you'd asked me, I use Golden Eye rom. I am on NC1. You can see that in my signature section.
I will tell you how I installed the Golden eye rom as an example.
I download the package (zip file), my NC1 stock kernel file and superSU file.
Using the safestrap I installed the package zip file. After the installation finished I installed the NC1 kernel file and SuperSU file. Then I reboot my phone. That is. Other roms might have different instructions.

As sway said, you do not need Safestrap to root, you just use Saferoot and you have root. However, you can actually use SS 3.72 and it would be better to use it since you can then mount /system even while on a 4.4.2 kernel. You can also use the single GPE located in the general section. Sway's ROM flashing instructions are correct, but also remember to flash the kernel module zip in Safestrap, and you would be using the MLD set since you have the MK2 bootloader. The kernels and everything you need are included in the KitKat Magic Toolkit.

:crying::crying::crying:
Sigh, I will admit, I have done it again, so I am back to flashing the MK2 file from a few post ago.
I think I will either go with stock rooted ROM or the GPE version, I think the only thing I am missing is the kernel, which I found in one of the post I have to Loki it since I am on AT&T, but I can't find the Loki software, or would that be using Odin as well?
The only reason I am looking to root this phone is so that I can tether. Traveling roughly 2-3 weeks a month ain't fun, but not all hotels have free wifi, so having my phone rooted and able to tether is like a life line. Also, after I tried GB, its wonderful! Apart from I can't find a good quiet time option, everything is awesome being able to use GB and AdBlock. Does either Sway or DeadlySin9 have a good recommendation for quiet time app/mod?
As soon as I get the phone back on stock MK2, I will be looking into either stock root ROM or GPE version. Thanks all! :fingers-crossed:

OK. @DeadlySin9, got the final question (hopefully :fingers-crossed
I am going to flash GPE version (here) and I will be following the direction on that, wipe, flash, kernel then reboot. You mentioned that I should use the MLD kernels, but which one is that in the Kitkat magic tool? AP_MLD, BL_MLD? And now I have SS 3.71 on the phone, would you recommend uninstalling that and install SS 3.72 instead, since I will be flashing GPE version anyway?
Also, what of this ROM (here)? I guess I can't flash this one?

Actually, neither of those work. There's one in the General section, with Safestrap in the thread title. That's the one you need. I do recommend going to 3.72 on Safestrap, and you need to use both the AP and BL files in ODIN.

Also, by the look of it, paid apps wouldn't work in this ROM, that might be a problem.
Here is another one that I was considering from the start (here), but I am not sure if I should follow the first post or second?

If you're still on MK2 then you can use the second one. And yeah, you can't download paid apps from the Play Store for some reason.

@DeadlySin9, thanks for pointing out the correct one to use, and yes, I am still stock on MK2, rooted and have not installed SS, pending the version discussion. I will go ahead and install SS 3.72 and the ROM from the first post and :fingers-crossed: that it will work wonders.
The reason that I am choosing this over the GPE, don't get me wrong, GPE I think is better, but no download paid apps is not going to work for me, some apps like, root explorer and a few others are a must on the phone. So that's a bummer. I wish it works, then I can just flash and be in peace.
Thank you @sway8966 also for helping out on this. I just freaked out when I found out the work phone was dead.....

Xposed and Safestrap on Lollipop?

I recently upgraded today from 4.4.2 to 5.0 OC4 and kept root using this method: http://forum.xda-developers.com/ver...0-keeproot-t3068546/post59791648#post59791648
However, I had no Idea it would be so hard (impossible?) to get xposed back. Is there any way in which I could install xposed ARM without having a custom recovery on my verizon G900V running lollipop?
I also read an article on another website that said you can flash safestrap with odin, go into safestrap, install anything necessary, and then reflash current ROM? I am not TOO knowledgable with all of this, however I have found my way around all this enough to ensure myself root and all needed features. Any help or information would be amazing.
Article: http://www.droidforums.net/threads/galaxy-s5-safestrap-after-the-lollipop-update.279867/
I was considering flashing the xposed ARM file with flashfire, however I read someone else was stuck in a bootloop who tried this. Would this not work? Is there any method? I was also looking into flash gordon which lets you flash .zip files without requiring custom recovery. Thanks!
EDIT: Just did some more research and found this thread: http://forum.xda-developers.com/galaxy-s4-att/general/nc1-flasher-odin-to-safestrap-t3082620
It seems as if its possible, however this thread is for the OC3 version, while I flashed the OC4... Anyone out there done anything like this before, or knows how to provide the needed steps? Thanks again.
Go to the xposed thread and read any comment at all. It doesn't work on touchwiz based lollipop architecture. PERIOD. you didn't need a new thread in this forum to learn that...
I see, is there some way that I could downgrade. I've been looking into that for awhile now to go back to my 4.4.2 but there's a ton of methods and I am not sure which is required for my device. I canno't seem to find a specific method for my g900v s5. Thanks for you're reply, and I hope I can downgrade.

You can go up and down as often as you like. I would Odin the NCG tar from the link below and reroot.
You probably still have safestrap. You could try this first. Go to download mode and Odin the NE9 kernel. When your phone starts booting up you should see the safestrap option to boot into recovery. Boot into recovery, install a rooted NE9 ROM of your choice. Boot back into download mode via safestrap and Odin the NE9 firmware. Let your phone boot all the way up and you should be good to go. Use NCG kernels and firmware-roms if you would rather be on NGC.
http://forum.xda-developers.com/ver...ment/stock-collection-kernels-modems-t2842069
If safestrap doesn't show up, Odin the full NCG tar file and reroot your phone.
Thanks so much for your help, the only problem is I never installed safestrap on my phone. So I do not currently have safe strap, or any custom recovery. So i can just use the odin method then, correct?

Yes, sir. That would be correct. Since you are rooted, there is an app called Flashfire you could use that doesn't even require a computer but if you are familiar with Odin that is a good way to go as well.

In Flashfire, select firmware and navigate to your firmware. Just check boot and recovery
Next select zip-ota, navigate to your ROM. Leave auto mount unchecked.
Select firmware again. This time check boot, recovery, modem, and firmware. Flashfire will ask if you want them in separate zips. Click yes
Now select wipe. Check everything but SD card.
Now arrange everything in this order

Ur amazing. I'll try it and let you know. Thanks so much for your help.
Thanks so much! It worked perfectly! I had a problem initially after installing towelroot and xposed and got an error when rebooting the phone called "Process system isn't responding". My phone kept freezing and was super slow because of this. I believe it was due to me restoring contacts from titanium backup. I restored the contacts system app as a whole. I didn't realize that at the time however, and just system restored my phone again, and did everything the same yet didn't restore my contacts, and the message is now gone. I am not running root with xposed on 4.4.2. Your amazing!

Acquiring lollipop from 4.4.2 nc4

Hello
First let it be known that i have searched my butt off and tried many different things. The best i could get was a rooted phone and a non working safestrap install.
Can someone please give clear instructions here in this thread to either a) install safestrap on 4.4.2 nc4 or b) let me know if it's possible to install verizons stock lollipop firmware using odin (no recovery required).
I would love to get a working custom recovery to try different roms. Failing that, id love to know if it's possible to just flash stock lollipop firmware on this device.
I'm sorry to make such a request, as my first post.. But have been rooting and roming and xdaing since the Samsung vibrant. I'm just tired of trying to make this locked bootloader work. I must've tried a hundred different things.
As of right now ive odind back to 4.4.2 stock with nc4 kernel and said root, busybox, and supersu.
I'm familiar with odin, flashing, all the terminology, and can find the files on my own.

Yes..you can flash stock firmware for 5.0 via Odin. You will lose root and as of this time....can not root 5.0
once on 5.0, you can only odin back to 4.4.4 which is also unrootable.
simplyeorange said:
Yeah you can go back to 4.4.4 I've read post of people on this forum saying they were able to get back to 4.4.4 you need to download the stock tar. Which you can find on sammobile than boot into download mode and then open Odin flash the stock tar. After its done flashing Then boot into stock recovery and do factory data reset. Wait about 5-10mins and should boot you into 4.4.4

Thanks for that. I'm sorry about the aggressive tone of my original post. I was just quite frankly mad at how much verizon locked the note 3 down. I own it, you know? Lol.
I wanted custom recovery mostly for the nandroid backups. If i flash the nc2 kernel on 4.4.2 with nc4 kernel... Supposedly this is supposed to make safestrap work with one rom slot (stock). I tried this but it soft bricked. Is there a custom nc2 kernel I'm supposed to flash?
Also if i odin the stock 5.0 files will this keep all user apps and data? I suppose i could use titanium backup for that but I'm not sure if it will be compatible from 4.4.2 to 5.0?
I guess i have to debate whether i want nandroid backup abilities or lollipop.

[Q] Please Help! Cant Flash Recovery!

Ive been going so crazy trying for about 15 hours total now trying to root and get a custom recovery on my phone, for some reason, nothing will work. I do have alot of experience with rooting and ive done just about everything, attempting to get this phone to flash a custom recovery.
ATT SGH i337
4.4.4
KTU84P.I337UCUFNJ4
I am currently rooted, but i cannot get a custom recovery. I have just tried this method,
http://forum.xda-developers.com/showthread.php?t=2297033
with that tool, however after running it, it successfully flashes the recovery, then boots me into the Odin Mode Download screen with the picture of an android. Same thing with trying any other method of flashing a recovery. Can someone please tell me how to get past this, im so exhausted trying to fix this. I tried factory reseting my phone from the phones settings and even that brought me back to the download screen with a picture of an android. I cant get into any recovery at all! Stock or custom it sends me back to that screen.
How can i flash a custom recovery and get this working? Thank you guys in advance

i installed the proper NJ4 safestrap apk and pressed install recovery, however it still says it is not installed "reboot to recovery" is greyed out. Upon booting into recovery, i am still stuck in Odin mode. Anyway for me to stop odin mode from continuing to come up instead of recovery?.
I would guess the system is looking for stock recovery, and it isn't there any more due to your flashing the CWM OUDHS recovery and/or TWRP. You probably need to put the stock recovery back.
I know and I've been trying to find out a way to do that. Could you help me if that's what I need to do? Once I reinstall stock recovery will safestrap work?
Sent from my SAMSUNG-SGH-I337 using XDA Free mobile app
I would suggest that you flash nb1 then nb4, root and install safestrap. At this point, a clean install is your best bet. Refer to this thread in the general forum.
U can get stock recovery back by either flashing the whole stock firmware via odin or extracting the recovery image from the firmware and flashing it by its self via odin I don't know anything about safestrap as I'm on Canadian version some one else can hopfully help u out with tht
I read what you posted and I don't entirely understand. Could you point to me to a download a maybe dumb it down a bit?

You are on NJ4 (I337UCUFNJ4). There is no flashable "whole stock firmware" for that version. There is a flashable whole stock firmware for the NJ1 version (I337UCUFNB1). Also, there is no easy way to "extract the recovery image out of the firmware and flash it by its self via odin." The reason for this is that you need a .tar archive to flash in odin, so if you extract just the recovery, you then need a Linux box, or a Linux virtual machine running on your windows pc to make the tar file from it.
This is why I suggested that you flash the NB1 full stock firmware, and then flash the upgrade to NJ4 from stock recovery, as outlined in the guide I linked.
As you asked for a little more detailed help, I'll try to walk you through following the Odin to Stock, Updating, Rooting, and Safestrap Guide.
First, read through post #1 and the FAQ in post #3. Next, you need to decide what version you want to end up with. Let's assume that you want to end with NJ4 -- KitKat 4.4.4. (If you want to end with OC3 -- Lollipop 5.0.1, then the instructions are a little different.)
In post #2, under the section titled NJ4 -- KitKat 4.4.4 expand Step 1 - Odin to stock. The files you need to download are at the top of this section. Follow the steps; they are pretty self explanatory. Part 1 installs full stock NB1, and Part 2 installs the upgrade to NJ4.
You are now on fully stock NJ4. If you want to root and install Safestrap, expand Step 2 -- Root and Install Safestrap. The files you need to download are at the top of this section. Again, the steps are pretty self explanatory.
That's it. If you want to now install custom firmware, you are ready, or you can just stay on stock if you prefer.

Yes and i did everything under the NJ4 Kitkat 4.4.4 section. I am rooted and everything worked except for safestrap. I open it and press install recovery and everytime it finishes it says "state:Not Installed". And reboot to recovery is greyed out. Upon manually rebooting into recovery mode, i am in normal stock recovery.
I cant use the selinux mode changer it says. To root i didnt use towelroot because installing the NC1 kernel disables my wifi connection, and since the phone has no service, i had to use KingO Root. I have confirmed root access using root checker. But Safestrap wont work.
What do i do? Is safestrap not working because i didnt root with towelroot? I assumed it didnt quite matter how i rooted. If it is because of towelroot, then how do i get towel root to work while on the NC1 kernel with no wifi and no cell service?
Update: I found a selinux Mode changer apk on xda and installed it. I tried it and safestrap still would not work and said "not installed". I also reflashed the NC1 Kernel and the same thing happened. I booted into recovery for confirmation.
I guess its maybe because i didnt root with towelroot? But it is impossible without phone service because flashing NC1 disables the wifi. Please reply as soon as you can
I can't help with your current issue with safestrap because I don't own this phone. I have worked on my son's S4, and a couple of others that have come through my hands. I have performed the exact process you just used with no issues.
I would suggest you post your issues in the guide thread where someone who has more experience with safestrap can help.

i337 came with 16 GB internal memory.
I am using OC3 based custom rom and I have 2.61 GB left in my internal memory.
You phone still might have old photos, music files, old system files there.
You need to backup and clean the old files (photo, music, document, etc..) before you start your new fresh installation.
I suggest you use flashfire to wipe the internal SD after you make backup of the data files to the computer.
After you do that your phone would not boot (soft-brick), so you need to install the NB1 firmware cooked by Muniz_ri via odin, root with towel root, install flashfire and install OC3 root rom via flashfire.
Then use flashfire to install lean custom rom. Install Titanium backup pro to freeze or uninstall the bloat ware too. You can follow the debloat guide for lollipop to uninstall the apps.
If you need firmware or rooted rom for my suggestion do let me know.

According to your spec your bootloader version is OC3. You can come back to OC3 or OC4 after you clean up the phone.
Like I said in my reply made in October, you need to back up every thing from the internal sdcard to the computer first.
Here is the step I mentioned in my previous post.
"You need to backup and clean the old files (photo, music, document, etc..) before you start your new fresh installation.
I suggest you use flashfire to wipe the internal SD after you make backup of the data files to the computer.
After you do that your phone would not boot (soft-brick), so you need to install the NB1 firmware cooked by Muniz_ri via odin, root with towel root, install flashfire and install OC3 root rom via flashfire.

If you need firmware or rooted rom for my suggestion do let me know. "
You can find the NB1 firmware cooked by muniz_rl at here.
That firmware is rootable with towel root. Get the towel root and root it. After the root, install the flashfire.
I could not find the OC3 bootloader so I suggest you flash the OC4 instead.
Here is the guide to flash OC4. The guide is updated for OK2 but you will be using the OC4 files instead. Just follow the steps.
Here is the OC4 bootlaoder.
Here is the OC4 rooted rom.
Here is the OC4 kernel. (You do not need it in the process, just to keep it handy for the future)
Once you are running OC4, you can install Titanium backup and freeze the bloatware. If you want to install the custom rom do let me know.

After you do that your phone would not boot (soft-brick), so you need to install the NB1 firmware cooked by Muniz_ri via odin, root with towel root, install flashfire and install OC3 root rom via flashfire.
Then use flashfire to install lean custom rom. Install Titanium backup pro to freeze or uninstall the bloat ware too. You can follow the debloat guide for lollipop to uninstall the apps.
If you need firmware or rooted rom for my suggestion do let me know. "
You can find the NB1 firmware cooked by muniz_rl at here.
That firmware is rootable with towel root. Get the towel root and root it. After the root, install the flashfire.
I could not find the OC3 bootloader so I suggest you flash the OC4 instead.
Here is the guide to flash OC4. The guide is updated for OK2 but you will be using the OC4 files instead. Just follow the steps.
Here is the OC4 bootlaoder.
Here is the OC4 rooted rom.
Here is the OC4 kernel. (You do not need it in the process, just to keep it handy for the future)
Once you are running OC4, you can install Titanium backup and freeze the bloatware. If you want to install the custom rom do let me know.

Info you gave me is enough.
If you phone die (brick), flashing the NB1 firmware via odin could save your phone.
Flashfire backup would restore the old system so I suggest you should not use the flashfire backup.
The back up is simple. Connect your phone to the computer via usb and copy and paste the data (photo, video, documents) to your computer.
Install the app like Netqin sync to backup your contact list. You can use google contact to backup your contact but it would mix the email and phone number.
Install the app like SMS backup to backup the sms message and phone logs.
Install the app like Titanium backup to backup the apps that you like to keep. (When you restore make sure to restore the app only. )
problem need help again
I was going through the posts and realized how helpful you were to a noob like me who helped me to install a stock custom rom i think i forgot to turn off the updates or something apprently my phone was initially stuck in bootloader the atnt now it wont even show the atnt logo keeping my fingers crossed that i havent screwed my phone

LRX22C. I337UCUGOC3
if i am not wrong i cant just install any custom rom since bootloader is still locked i dont know for sure
in the screen below
#manual mode#
--applying multi-csc
applied the csc-code: ATT
Successfully applied multi - CSC
what have i tried uptill now
just wipe data/factory reset
can you help ?
It sounds like you need to flash the OC3 firmware using your computer and a program called ODIN. No, you cannot boot any custom ROM you want. You can only boot custom touchwiz based ROMs because of the bootloader lock.
