Hello all,
I have had my S4 for awhile now and need some help. When I first received it, I did some reading, rooted, did something that removed a triangle or a padlock, can't remember which one and made sure the AT&T software update was unable to run. At the time, custom recovery wasn't possible so I stopped there. So here I am now, rooted with MDL and I have no idea where to go from here to get the latest 4.3, although apparently I have the holy grail of firmware.
I've read as much as I possibly can, subscribed to the forums, GOOGLED, SEARCHED, RTFM and waited for someone else to come along and ask the very same question. Some did but those threads never really gave me the info I need to SAFELY flash my phone up to 4.3. So what do I do? All I need is some guidance, I follow directions well. Teach me! Please and Thank You
Doug
DO NOT UPDATE YOUR FIRMWARE IF YOU STILL HAVE MDL. ....U JUST NEED INSTALL CWM RECOVERY OR TWRP RECOVERY. .... AND THEN INSTALL CUSTOM 4.3 ROM. .... EVEN 4.4 KITKAT ROM. ..... BUT IF U DO UPDATE TO NEWEST MK2 FIRMWARE THEN U WOULD LOSE THE PRIVILEGE OF MDL..... WHICH IS RARE. ..... GOODLUCK

Right! One of the things I have learned is that I want to keep the MDL baseband. What I really want are all the improvements that 4.3 or 4.4 offer. Also, I'm hoping my Pebble and my S4 play better together than they do now.
Do I just pick a recovery? Are they the same? Guess I need to read some more.

As ted said, upgrading is bad. You can change modems and such to the MK2 baseband, it's the bootloader that's the issue. As long as you don't try to take any OTA's and don't ODIN any newer version you'll be fine. If you want to run the official AT&T 4.3, your closest bet is StockUp MK2 and the rebloat addon. Otherwise, you can choose either CWM or TWRP and flash away as long as you remember to use the loki patch for things that aren't patched already.
I've read the info at the link you provided before and wondered if I'm already rooted, what would happen? Is that safe to use if currently rooted?
Also, since I'm currently on MDL, would a factory reset return me to a fresh MDL or would it force me to update to current software?

Ok so I strated with the thread posted. I now have TWRP installed, nandroid backed up and all sorts of zips on my ext card. Also made Kies backups. My first ROM flash, Stockup_MK2 went fine until reboot and I had no mobile data or cell signal. What did i do wrong? I immediately did a restore from the nandroid backup to return to where was before.

Did you wipe before installing the rom? Just use the slider toggle in wipe. If so, check that the apn is setup correctly.

In stead of a stcok MK2 rom might I suggest a fairly stock but cleaned up rom like MDOB or any other close to stock rom's
http://forum.xda-developers.com/showthread.php?t=2280556
Not advocating any one person but he does good stuff and it based on the actual AT&T update to 4.3.. Make sure you do as the guy above me stated and do the simple swipe to wipe in TWRP
Hi,
I am looking at flashing some custom roms to see which one I like, I have got root by using the cf-auto root by cahinfire but, before I begin I just want to make sure that I back every thing up correctly to avoid any trouble further down the line.
As I understand it ( I use the term 'understand' loosely ) I need to back up the EFS folder and imei
Is that all that is needed? or is there something else that i should do? essentially I would just like to ensure that I can revert back to a stock rom, im not that concerned about knox or warranty. Im sorry if this has been brought up before but as a novice I would appreciate some assistance in gaining a proper understanding of the requirements before starting off
thanks
Backing up EFS has it's pros and cons - I done it, but then I got a mess up, and restoring my EFS did not work. I had to run the fire script posted in the dev section (this script rebuilds your EFS partition so it can be read properly again) - I have seen countless users brick their devices by backing up EFS with bad/rogue apps, so if you go this method, choose very very wisely.
My advice, install CWM, and make a back up via that. - it'll see you right. - If by chance you do get a mess up, you can run the fire script by firausman in the dev section and it'll fix unknown baseband and bootlooping errors.
Ultimately, I cannot stress that you read as much as you can and are aware of the potential what can and does happen, what cannot happen and ultimately can you fix it if something does go wrong.
EDIT:: here is the SCRIPT if you do indeed need it, keep it on your extSD Card for just in case reasons.

Thanks for the reply and advice Radicalisto.
I will check out CWM and how and what that backs up. If I take a guess now it will make an image of my current system that can be restored? If so does that ensure a back up of efs folder?

CWM offers an EFS backup yes, it has to be done seperate to the IMAGE back up though. Also note if you back up a 4.3 ROM on MJ7 firmware you cannot downgrade to a lower version ie: MJ1-2-3-4-5-6 etc - you can go to MK2 and back to MJ7 though.
Similar if you back up a 4.3 and upgrade to 4.4.2 then that backup becomes useless as it cannot be restored.
CWM - Install custom ROM, keep that script I posted close by, and you'll be 100% :good:

Thanks alot for your assistance im going to get the back up sorted and read up some more there is fair bit that i need to understand before flashing
Wise words my friend. Read up and understand are the two most important words of advice anyone can give and words that anyone should take heed of.
Good luck, if you run into problems, just holler :good:

so far the best thing I have come up with is to flash the latest 4.4.2 stock rom, I think this is the best option until some of the custom ROMs develop along a bit further.
but this leeds to a few more questions (I hope its not too much of a bother) Im going ( i think) to download the rom from Firmwares|SamMobile but it will be from another country(im in Australia) could this affect the perfomance of the phone in anyway or can I just flash other modems/radios in order to fix any problems that may occur?

ok now I have a problem I just tried to root the phone again with cf autoroot and its stuck in a boot loop. I cant get it back in download mode or recovery any suggestions
all good i got back into download mode hahaha *stops having a heart attack
Hello all, I posted a similar topic a few days back, and cannot seem to find it. I fear it was deleted, but could be wrong. I only looked back a few pages in the history.
My problems have multiplied since that posting. I have nc4, when I bought my phone it was on there. Used towelroot and was able to root, download safestrap 3.75 and was able to add/delete slots, attempted to use hyperdrive, experienced a lot of weird things like my SMS would randomly not send, battery life was not spectacular,and just other misc things. IT seemed like I might have used a rom that could not be used properly for nc4. I then tried bajarom, which completely does not work for my phone, probably because it's nc2 and I didn't realize that?? Tried jellybeanz or whatever the exact name was, my phone won't even boot, says it successfully installed but sticks on the black screen.
Somehow over the past few days I managed to wipe my stock so I do not have the stock, thus I cannot go back.
I am sure I can find or maybe be directed to the stock firmware and reflash it.
I am not sure if it's possible but I'd really love to be able to get nc2, or if someone more knowledgable than myself could point out a solution for me, I would like to have a custom rom if theres one that would work properly on my phone.
Another confusion I have, with the nc4, am I able to use odin to flash a different radio, should I even bother? I would sincerely appreciate someone who would help clear some of this up for me, I'm pretty novice as you can see. Thanks in advance.
update
I guess my question is unclear. I really can use some help if anyone would be so obliged.
I am trying to use ADB to push the file over, it says access denied, I was previously rooted and verified as much. My issue is I need a way to send the roms over to my SD or my regular phone internal mem so I can at least load a rom. Currently my phone is bricked and I am just getting very upset, I really could use someone to give me a bit of guidance.
I opened the cmd with admin and it's still saying access denied. IS there a way to force the phone to open as a media device via cmd? That way I can edit sd card info and push on there what needs to go?
I am currently trying to find a way to get hyperdrive, or another rom over.
I have beanstowns rom on there, it appears as .zip yet when I try to install from safestrap I end up exploring the directory, as opposed to just being an option I can choose.
Baja is the same way, both are still on my sd, yet for whatever reason I cannot select them to install them.
Hope is not lost.
I think your initial problem was that you tried using rom slots. It specifies in the Safestrap OP that rom slots are only supported on NC2 bootloader. Since you are on the NC4 bootloader you cannot go backwards, however you can flash the NC2 kernel if you want to run a custom rom, you simply need to use the stock slot alone.
Since I know very little about ADB & Terminal CMD, I will try to give you directions to get up and running the way I know how.
First you'll need to reflash the stock NC4 tar via odin and reroot. Files can be found here.
Since you've flashed a couple different roms that have probably messed with the system settings I would do a factory reset before rerooting.
After you are up, running and rooted, follow the instructions here to get on the NC2 kernel.
Once you've completed these steps you will be on the NC4 bootloader with the NC2 kernel and be able to flash a custom rom in the stock rom slot. Only a NC2+ rom will function so make sure it is based on NC2/NC4 (i.e. jelly 'beans' will not run on NC2+ firmware as it is based on MJE).

firstly, thank you so much for the reply.
I did flash nc2 kernal, but was confused when I still saw nc4 in the about section. I flashed with odin NC2_modem_kk.tar and nc2kernel.tar.
The issue I was having is with hyperdrive, and baja I had some serious issues, so I assumed it was because I was using them incorrectly, ie didn't install one of the above files correctly, or did something else wrong in the process. Just for example, with hyperdrive, my sms would just stop sending/receiving/ double sending. My sim card was not being recognized. And a whole lot of other issues.. So I kept messing around and now im at a point where nothing boots up, I cannot reflash, and I'm just stuck.
I will follow your link and attempt to do as you said, will wipe, and then will try again.

Alright, I applied to nc4 and did a factory reset, made sure all my slots were deleted (had 2). Then factory reset and rebooted, saw safestrap, pressed continue, and i'm looking at a blank screen now as though there is nothing to boot to. I was under the impression factory reset would undo all and it has not.
Did I do something wrong, or am I missing something?

Did you already boot into download mode and flash the correct files through Odin? If so that should set your phone back to stock. Then you would have to re root.

Seriously, just Google for the Samsung official firmware. It's on their site. Not Verizon.
Hello. Sorry for the noobie question. I tried to search the forums, and I did find the noob beginner guide, but I still wasn't sure, so I prefer to ask before I screw up my phone lol.
I have the AT&T SG4 SGH-I337 Phone. It was fine before it was upgraded to 4.4.2 (I didn't want to upgrade, but it did it on its own one day). Once it went to 4.4.2, everything is just DOG SLOW. I mean everything. In Car Audio takes forever to connect, phone calls takes like 5 secs to answer, even after I press the answer button. To unlock the phone I have to press the code 2-3 times, as I can see the keys I press is lagging behind.
What I wanted to ask is this: How can I bring this phone back to the previous OS? Or How can I modify this phone to a stock OS, where all this bloatware crap is not installed?
All I care for is my Bluetooth, in car audio and calls and have a phone that's fast enough as it was originally.
can someone point me to the right thread where it gives me step by step instructions? Ive never modified a Samsung Phone before.
I found this thread, but wasn't sure if its the right one for my phone.

Assume you are now on NC1
Believe you will need to Odin back to NB1 then update to NC1
If you want to root other steps involved--This thread covers it pretty well
Some one else more familiar can be exact, as I am on old bootloader and no handson exp--
Read the OP on the link very well and generally not a good idea to use links outside xda unless you are 120% sure of what you are doing--good luck--

I would suggest getting the Google Play Edition rom as stock android is much better optimized. Tutorials are available on the all things NC1 post. This will require root and installing a custom rom. Your warranty (if still applicable) will be void if you choose to do this. Regardless, the software on the device is not well optimized and the touchwiz UI is unnecessary imo. The GPE rom also does not have the samsung or at&t bloatware.

Use the "All things ATT" link rugmankc gave you. In the first posts in that thread you will get links to the root method, safestrap, and a list of compatible ROMs. A few thoughtsL
1. Before making any changes to you phone, charge it to 100 %, unplug the charger, and let it sit idle for some number of hours. Then check to see what services are using most of the power. For a while my own 4.4.2 GS4 was slow, and it turned out to be google play framework services bogging things down, and this showed up as an excessive battery drain during idle. If you phone uses more than say 0.5% battery per hour when completely idle / screen off (but with cell and wifi on), something's up. Fix it and maybe your problems will resolve.
2. Next step: back up any data / photos etc. and do a factory data reset from the settings menu. After it has been reset, perhaps whatever problem is going on will be cleared up.
3. You don't need to root the phone to ODIN a stock firmware (NB1 then flash update to NC1). Links are on the ALL Things ATT thread. This should take it all the way back to proper NC1, bypassing any mess that might have happened if you got a corrupt flash during your OTA update.
If the phone still performs so poorly as you describe after a flash back to stock, there's a problem that's more than the OS/ROM. Sure, the stock build is a bit laggy and bloated, but it's not so bad as what you are seeing.
If you find a restored stock ROM to be better but still laggier than you like, I have had good results with the GoldenEye ROM, flashed according to the instructions in the ATT thread. To flash, you must first root and install safestrap (selinux mode changer set to permissive may be required). You then boot to the safestrap recovery, wipe everything but the SD card, then flash the rom, SuperSU, ATT Module, and ATT BuildProp/APN. That should get you up and running on a new ROM.
I'm a died in the wool geek but I read through this forum and others for two weeks before attempting... but I'm very happy with the phone as it works on GoldenEye. I'm on V36, but V38 is current.
Good luck

Thank you very much for your help. Yeah everytime I redo my phone, from scratch, it works OK for about an hour. Then bam, it goes back to being a low pain in the rear. This is ONLY after the phone upgraded to 4.4.2. I didn't choose that upgrade, actually I didn't want to upgrade, but OTA upgrade took over and BAM, I got screwed.
OK I just installed the Safestrap and rooted the phone. Now I gotta figure out the rom part.
Im still going thru that link that rugmankc gave me above. Now im trying to figure out how to change the OS, since I just rooted the phone. I have to do this. Ive gotten really really tired of the phone being so slow, I basically give up on many tasks that I need to do, just cause its too slow.
Ill update once I get it figured out, hopefully I wont brick it, that's the only thing that im afraid of.
Don't remember, did you consider Odin back to stock and start over. If not, whatever was causing the slow downs may still be there. Could have been a bad update.
Read the SafeStrap thread by HashCode carefully. I read the OP 100% and last 30 pages or so of thread and don't even use it. It is complicated to me. IE which slot to flash to stock or rom. I think stock, Flash Modules. Install Selinux and set to permissive. And using correct SafeStrap. Gives me a headache and I am not even needing to use it--
Good Luck--as mentioned just backup whenever you can before moving to next major step. :good::good:

Thank you. Actually I backed up my phone already, as I reformatted it last night again. I don't know how to Odin back to stock. What is that? Is that a stock Android? Sorry I don't know.
Thanks...
It's in the same All Things ATT, MK2 thread under Returning to Stock Odin. An option if you still have issues. Takes you back to stock NB1, firmware and all. Kinda like your update, but think you may have got a bad update. Other options are to wipe internal in case bad stuff still there. Frankenscript was pretty thorough--:good:
SafeStrap is how you are going to flash a new OS/Rom. You can't flash custom kernels and aosp roms unless TW based like a couple GPE mentioned.
Read/Scan the two mentioned threads, as in OP and first and last couple dozen pages. Probably the last are more important. You will see folks asking the same questions you will eventually ask. I have read thousands of pages over the years and it has kept me out of trouble--most of the time--

Man, that link really got me confused as heck lol. Ive been reading that link the entire weekend and still im a bit confused.
I rooted the phone with towelroot. Ive installed SafeStrap, but it worked the first time I ran it. Now if I want to run it again it crashes my phone. Not sure what that is about.
Either way, now my understanding is that I should be able to download a rom for my phone and flash it. From that link that I was given, its very confusing.
Could someone PLEASE PLEASE help me here with this?
My phone is an AT&T US SG4. Here are the details:
SAMSUNG-SGH-I337
Android 4.4.2
BaseBand I337UCUFNC1
Kernel Ver 3.4.0-1125940
Build # KOT49H.I337UCUFNC1
Which ROM can I use for my phone? As long as its stock, I don't care which version, Google Play ROM or CY or Golden, whichever, as long as I get rid of this crappy Samsung and AT&T stuff off my phone.
Could someone please help me out here? I know that link says everything, but jeez, im trying to make sense of it, and so far, I got the phone rooted, but just cant figure out the ROM part.
Thanks...
I can't help with specifics as I don't need SS.
Make sure you have correct SS--3.72, afaik
Flash, I believe, to stock slot not rom slot but confirm that
Install Selinux app from Play and set Permissive--afaik
The above items are things people get into trouble with, so reconfirm them
Just keep reviewing the thread and the SafeStrap thread in Dev section by HashCode. Maybe go back more pages from end of threads as you have time. You can post in All things thread now for help and at 10 posts in Dev section. It will come together in time--:good:
Flash roms only for you build, think there is a list within that thread or another one in General or Q&A.
iB's Goldeneye 38 is good and you can use the Aroma to select SafeStrap and the Slimmed down version.
Read his SS flashing instructions first.
Make sure you use SafeStrap recovery to wipe ALL--System/Data/Caches before flashing--:good:
Cornelp: Having recently been through all this, I wrote up a short summary with some links for another user, and it might help you to look through it. It's an overview written from my end-user perspective, not a replacement for the detailed posts the devs have done.
However, based on your description, I would say the best thing to do is ODIN back to stock because I have a sneaking suspicious you got a bad OTA flash. It happens. Going back to stock will be the best way to eliminate that as a source of problems. Learn how in the All things ATT thread OP.
Best of luck to you!

Frankenscript,
Thank you very much, I will read up on that link you gave me. How would I ODIN back to stock? Do you have specific details on that? I did read something about that on the All things ATT, but wasn't clear.
Thanks...

Complete instructions here:
http://forum.xda-developers.com/showpost.php?p=51130818&postcount=5
Basically, download ODIN to your PC, run it, get phone into download mode, connect phone to PC via USB, in ODIN select the NB1 file, tell it to start. When done, reboot phone. Then flash the NC1 update from an SD card using stock recovery.
A good pictorial description of how to flash can be found in this S3 thread here:
http://forum.xda-developers.com/galaxy-s3/help/guide-odin-flash-guide-t1671969
Though for a different phone (the S3, not our S4), the process is still the same.
Good luck. I'm headed off to a work trip and won't be on the forum much this week!

Thank you all. I was able to revert back to the NB1 stock, but it failed the first time. I had to download and install the NB1 Rootable Odin. For some reason, the NB1 Odin didn't work, but the Rootable one worked.
So im glad I was able to go back. Now I just gotta test it and see if it does slow down as it did before. I will post update, in case anyone else has the same problem, maybe this would be a good solution.
Thanks again to all of you guys, really appreciate it. I really hope it worked.
Hi, bought this phone yesterday, and flashed the rom of the dev adition, and lost my radio, was lucky enough to get best buy to take it back. I got another one though, and I was wondering if there is an official marshmallow downloadible rom for this phone. Don't just want to flash the ota, want to get the entire rom, and I am bootloader unlocked. Also, is there a cfautoroot for this phone on marshmallow.
Thanks in advance
FYI this is a good way to get raged on.
please search before you ask questions that are and have been answered in other threads.

1. do you have custom recovery if so see http://forum.xda-developers.com/mot...rom-stock-rooted-debloated-x1575-6-0-t3262242
2. if you want to start over with a clean slate see http://forum.xda-developers.com/mot...rom-stock-rooted-debloated-x1575-6-0-t3262242
This is what I am using after not being able to get OTA http://forum.xda-developers.com/showpost.php?p=65965064&postcount=2
Honestly you should not be flashing anything. Ever.
I'm totally blind and these forms are super hard to navigate through the cludder with
Hi, I am a very technical person, who has a masters in computer programming, I work with linux and just about anything, but I ask questions that may have already been asked, because if you have ever used a screen reader, with the banners and so much cludder, some times I can find the answer, and sometimes I go through pages and pages, and can't find it, and you guys find it easily, so what am I missing. I just want to be on the latest rom, be rooted, and have a custome recovery. Can this be done with cfautoroot on the xt1575, because beeing blind I have to do everything through fastboot as much as possible because my wife will help me some times but usually she gets very frustrated when she has to work twrp and install things for me, so sorry for the ramble, but that's why I some times ask questions that have already been asked.
Thanks

Fastboot flash twrp and download the newest rooted w security update and flash, what I did was flash the non rooted to get everything, then flashed rooted to get root. I can understand that there is a lot of clutter. Wish I could do it for you I deff would
so no problem, what wipe should I do before the flash of the rom, cache, dalvik, and data? Also, does the rooted deodexed use a different baseband or modem, and is there any advantage to deodexing in this day and time, I heard that most of these roms these days were actually not odexed anyway, just asking and learning
Do not do not use fastboot to wipe anything. Download the regular from the link above and the rooted and put on SD card. Flash recovery in fastboot use bootloader to get into recovery(otherwise phone will overwrite) wipe everything accept external in recovery and flash the ROM with February security patch
https://www.androidfilehost.com/fid=24459283995299100
Then after it flashes completely flash https://www.androidfilehost.com/fid=24459283995302251
Then let reboot. I did this with no issues.
