[Q] Cannot update bootloader?

Hello, I was originally running a beta version of Panandroid 3.99, and then I flashed a Stock modified Tmobile Rom on 4.3. I wanted to see if I could get wifi calling to work on it and it did, then I wanted go back to Quantum Rom.
For some reason I could not get Quantum Rom to flash, TWRP would read a "unable to .zip or something like that. Then I read I should update my Bootloader and Modem. So I restored an old backup to Cyanogen mod 10.1.2 (4.2.2 Update). I was able to flash my modem to the MJB update, but whenever I tried to flash my bootloader to the MJB update, TWRP and CMW would both give me Status 6 errors.
I am currently on the LK3 modem as stated by my Terminal Emulator.
Any suggestions on what I should do?
I'm also confused on how I was able to flash Panandroid 3.99(4.4.2 KitKat) on the LK3 modem? Should I have needed the MJB modem in the first place?

The bootloader and device ID is normally what determines if a rom can be flashed to a phone, not the modem.

Visit the S3Rx post and scroll down to the download area and you will see the modem and bootloader flashable zips. I would go with the MJ2 bootloader /MJB modem combo to allow you to go backwards in bootloader if needed.
You may need to update TWRP to the latest, I understand that 4.4 roms require the latest.

I think you meant the MG2 bootloader, which did install fine. After that, I was able to flash Quantum and GAPPS.
Thanks a bunch! :highfive:

Glad that fixed the issue. :good:
Actually, I meant MJ2. Interesting enough I now see is not on the boot loader list thread (http://forum.xda-developers.com/showthread.php?t=2321310) and appears to only be found on the custom 4.3 TW roms sites (which references to the S3RX rom thread (http://forum.xda-developers.com/showthread.php?t=2252932).
LK3 - 4.1.1
MG2 - 4.1.2 (OTA)
MJ2 - Leaked 4.3
MJB - Official 4.3 (OTA)(make sure you read the warnings if you go to this boot loader - there is no going backwards)
So unless you need to go to a 4.3 boot loader, which it sounds like you do not, I would stay where you are.

saftest method to take my i747m 4.1 to 4.4 ?

someone please link me to it ?

If you need to ask, I strongly recommend to have your carrier do it. If you are under warranty and they screw it up, even better.

lol i m pretty good with rooting/roming stuff my dear..have been doing since 4 yrs back from s1 days...its just that i was outta the s3 scene since one year n when i recently logged on have been hearing abt people bricking their phones trying to upgrade hence thought any senior member would b able to shed some light !

this might help...

i used it going from mj2 > mjb > NE4.
good luck. make backup. read.
err on the side of kindness

If you are sure you have the i747m and not the i747, you can flash the 4.4.2 ROM from sammobile.com using Odin.

yup its a i747m..but still anyway to confirm it ?

What baseband and bootloader is on your phone?

android 4.1.1 i747m baseband-i747mvldlk4..so whats the safest method now to go to 4.4 ?

Flash back to stock LK4 using firmware from sammobile.com and run OTA updates to 4.4.2.

any other alternatives ? my phones already rooted/custom recovery installed..also i would prefer a custom 4.4.2 touchwiz rom ?

cant i straight away download the stock firmware from sammobile 4.4.2 for i747m & update manually via odin ?

You can. I suggested starting with 4.1.1 because it's easier to revive the phone if something goes wrong when flashing 4.1.1 in Odin. If something goes wrong when flashing 4.4.2, it could be harder to unbrick.

Can I flash the system and boot .img's if I'm on UCUEMJB?
Its been a looooooong time since I've touched an S3, and happened across a pristine example to use for work. I'm pleasantly surprised to learn I can flash a custom recovery on this still.

This works 100% from NE4. Don't know about coming from another but from NE4 it works.

Just updated to NJ1 THANKS @enewman17 you really are the d2att GURU!

Question about the two zips
Flashable Rooted NJ1 system.img and boot.img is everything and root. S3 recovery is same thing just not rooted? Sorry if it is a stupid question, but I am making an emergency folder for my s3, and since i already upgraded to the NJ1 modem/bootloader, I have to be careful to flash an updated rom, right?

First, thanks for all your great work enewman!
Second, somewhere between Paranoid Android 4.45 and SlimKat 4.4.4 I lost my GPS signal too. I was on some pretty old firware, so I followed enewman's instructions in this and another thread and got my bootloader and modem all the way up to NJ1. I checked my GPS function every step of the way, but it never came back.
Then i found this thread about GPS problems over in the CM forums:
http://forum.cyanogenmod.org/topic/99965-gps-issues-with-latest-nightlies/
Post #8 in the CM forum thread describes how to rebuild your NVRAM once you're in a stock AT&T ROM; appropriately enough, part of their solution links back to an older enewman post for an NE4 stock update. I followed their procedure exactly except I flashed the rooted UCUFNJ1 ROM from this thread. Once I rebuilt the NVRAM, voila GPS came back! I use an app called GPS Test that sometimes seems like it has an easier time getting a fix than others. Throughout the whole problem, it reported no satellites visible. Once NVRAM was rebuilt GPS Test sees 23 satellites and fixes in a few seconds.
Next, I restored SlimKat from a TWRP backup, and sure enough the GPS fix stuck. Now everything is working again :laugh:. I did have to have GPS Test clear AGPS data to get more than 4 satellites visible at first in SlimKat.
Hope this helps you! As always read carefully, do your research, and follow all the steps carefully. Good luck!

ODIN?
Is there an ODIN file for this? I want to update my bootloader and modem to NJ1, but I don't have a custom recovery installed due to wanting to leave my warranty bit at 0 until the warranty is up.

Anything new worth noting in this vs. earlier KitKat builds (NE4, NE6, etc)?

Did you flash the NJ1 bootloader & modem? If so then you need to backup your internal SD to a PC or ext sdcard, & (manually) wipe system, data, cache,dalvik, & internal SD in recovery (manually wipe everything but extSdcard) & then flash again. When coming from AOSP back to TW or TW to AOSP you should always do this. The data on internal SD is causing the issue! Make sure you back it up & do a 100% clean flash, you'll be surprised how fast it'll boot afterwords!! Need to be on NJ1 bootloader & modem, & never skip any when upgrading for example- MJB to NE4 to NJ1, If you skip you'll have trouble, & not the kind easy to fix!

Stock NE4 Rom and Firmware?

I'm currently on MJB and I'm looking to update my bootloader/modem combo to the NE4, but before doing so I'd like to have on hand a stock NE4 Rom to fall back on if needed (since I can't use the stock MJB one that I have at that point).
I've been looking around but can't seem to find a Stock NE4 file. Can anyone point me in the right direction? Thank you.

There is no stock NE4 firmware because AT&T never released it and was only available via OTA updates.

I guess what I'm trying to get at is how far can I go updating and still have a safe way of recovering to stock if anything were to go wrong?
(I used to flash LK3 stock when I'd run into problems and just go from there, but I understand with these you cannot downgrade or it'll brick)

http://forum.xda-developers.com/showthread.php?t=2788357
"all i can really do , is stay out of my own way and let the will of heaven be done"

There is no stock AT&T ROM beyond LK3. Once you are on mjb, you can only flash stock ROMs that have been specifically compiled for flashing via Odin or TWRP/CWM.
If you want to revert back to stock from a custom ROM, look for stock flashable ROM on the general section of the i747 forum.

If you are still on the original bootloader and modem you should be able to revert to stock 4.1.1 by simply restoring the backup from your recovery. Before you attempt to do so verify that you are indeed on the 4.1.1 bootloader. This can be done with the Phone Info *Samsung* app by VndNguyen (?sp) from the playstore or by a couple of terminal emulator commands:
Code:
getprop ro.bootloader
getprop | grep version.baseband
If you do not already have terminal emulator installed, it may have come with the ROM, you can get it from the Playstore. It may also be a part of CWM recovery, it is part of TWRP I know for sure.
If it turns out you are on a newer bootloader and modem then go with a stock ROM that matches the bootloader and modem on the phone. To run a lollypop rom you will need to be on at least the NE4 bootloader and modem.

Thanks for a very helpful reply. I m going to follow your instructions. Will soon replay. Thanks again.

You are currently running the LK3 bootloader and modem. If I am not mistaken that's a pretty old one (original?). You will have to update to NE4 or newer firmware before you can flash any of the newer roms. They will not boot in the older ones.
Your firmware is actually the only one available for download so I recommend flashing it via Odin and factory resetting. Then update using the Software Update option in Settings > About Device.
You can download your LK3 firmware here: http://www.sammobile.com/firmwares/database/SGH-I747/
You may have to run Software update several times to fully update.
That is probably the safest and easiest course you can take.
After that, flash the latest custom recovery of your choice, then flash the rom you want.

BTW, after flashing the LK3 firmware, you might want to consider using the free Sim unlock method. (Should be pretty easy to find).
Once you update past 4.3 you can no longer use it. It will allow the device to be used on other carriers networks, which can be beneficial if you ever want to sell it or switch carriers.

What DocHoliday77 suggests is probably the safest method to get what you want. After each update the system will force you to wait 24 hours before you can make the next update. That would be three days to get to NE4, the first 4.4.2 release by AT&T, which you need to run lollipop ROMs. If you want to update to the current release (NJ2) that would be two additional days.
You can shortcut the required waiting period by manually advancing the system date after each update.
In addition to not allowing you to use the free unlock, once you take the 4.3 bootloader it prevents you from downgrading bootloaders. Newer bootloaders do the same, downgrading will be a thing of the past. (I never took the official 4.3 bootloader until the stagefright scare came along and I went from my older custom ROM to a new release.)

When you say original bootloader I don't know which you have. My i747 came with 4.1.1 but before I could get it out of the clerk's hands they had taken the OTA to change it from DLK3/4.1.1 bootloader and stock rom to MG2/4.1.2 bootloader and stock rom. Even more confusing I have read reviews that state the SGS3 was originally released with android 4.0.4.
If your original bootloader was older than 4.3 (MJB) AND you have never upgraded to MJB or newer, then you can safely return to stock 4.1.1.
To get OTAs you need to be on the stock ROM, at least you do in the USA. I don't know if that holds true elsewhere.

I can confirm the S3 was originally shipped with 4.0.4! We were updated pretty quickly though.
As for the OTA'S, you do have to be full stock, not rooted. But you also have to be on AT&T network.
I don't know how far back the OTA'S are hosted around here, but enewman17 has several threads that provide the more recent ones. Hopefully someone will have the older ones. If I am not mistaken, you will have to update incrementally once you reach 4.3. (it's probably safe to jump straight to a 4.3 build if you can find the right firmware for it. But don't hold me to that as I am not 100% certain.
I'll look to see if I can find something you can use too.

As per I am out of att network and I can't get OTA,s so I don't need to revert to 4.1.1 backup. I think I have to find out 4.3. For my device. So kindly please inform me if some one knows about .

I got this while searching online. Please tell me if it is helpful for.me.
http://androidromupdate.com/att-samsung-galaxy-s3-sgh-i747-odin-stock-firmware/

Never been to that site, but it looks OK to me. Nice find in fact! All the usual firmware sites stopped getting the AT&T firmware a while back.
Anyway, just to clarify, LK3 is 4.1.1. UCDLK3 is just the build number.
If you want to get fully updated, I suggest Odin flashing the MJB (4.3) firmware. Then flash each of the OTA's until you are updated to where you want to be. (I would fully update, but that'll be up to you.) The OTA'S are intended to be flashed from stock recovery, but there is another option if you want to try it. Mobile Odin is an app by chainfire. It does require you to be rooted, but it will flash the OTA. Read his thread here on xda to learn more. It's one of my favorite apps tbh! Once you learn how to use it it makes flashing quite easy.
So my recommendation would be this:
Flash MJB with Odin.
Root using Towelroot (easiest root ever)
Install Mobile Odin and flash the OTA'S.
I hope that clears things up a bit!

(I would fully update, but that'll be up to you.) The OTA'S are intended to be flashed from stock recovery, but there is another option if you want to try it. Mobile Odin is an app by chainfire. It does require you to be rooted, but it will flash the OTA. Read his thread here on xda to learn more. It's one of my favorite apps tbh! Once you learn how to use it it makes flashing quite easy.
So my recommendation would be this:
Flash MJB with Odin.
Root using Towelroot (easiest root ever)
Install Mobile Odin and flash the OTA'S.
I hope that clears things up a bit!

Update:- I am stock 4.1.1 now . I restored the device from custom AOKP kit kat rom using the stock 4.1.1 backup which I have made via CWM recovery. The device is running perfectly.
*****tried to run OTA but it says ur. Device in up to date . Means I cant get any OTA up date . So the question is can I get any custom lollypop rom using this older bootloader. ? (LK3)

To be able to run a lollipop rom you will need to update bootloader and modem. Update them together, this is important once you reach the 4.4.2 level of bootloader and modem that you will need to run lollipop roms. Once you reach 4.4.2 you will brick your phone if the bootloader and modem versions are not the same.
Before starting to flash any of the files you need to get you up and running on lollipop, I strongly suggest you download all you need from start to finish. Store the files you will need in the upgrade process either on an external sdcard or on the root of your internal sdcard. I haven't used CWM Recovery on my SGS3 since shortly after rooting it, I have been using TWRP since then, and I don't recall all of the capabilities of CWM recovery. If the CWM version you have will not let you flash from an external sdcard you will need to store the files you will use on the root of the internal card to be able to flash them. It will be easier to do this before you start, unless you are comfortable with pushing files from a computer using adb.
BEFORE DOING ANYTHING I AM SUGGESTING read enough that you thoroughly understand what I am saying. After reading, ask questions for clarification. Be sure you have no doubts.
Decide if you intend to install a rom along with the bootloader and modem at each upgrade; or if you are going to install updating only bootloader and modem until you get them to them point that you can run a lollipop ROM. Since you said you can not do OTA updates, either way will work. Whichever you decide, you can not skip directly to the bootloader and modem you need for lollipop.
If you are installing bootloader and modems without the rom:
From the stock 4.1.1 rom and bootloader you can go straight to 4.3 bootloader and modem, skipping the 4.1.2 (MG2) version. I have personally done this with no ill consequences. After 4.3, install the first bootloader and modem version for 4.4.2, that is NE4. Lollipop will run with the NE4 bootloader. As DocHoliday stated, you can go on the the current bootloader and modem. After NE4 is NJ1. After NJ1 you come to the current bootloader and modem, which is NJ2
If you plan to install the full ROM at each step.
The page you linked to should work if all of the downloads are available. Go from 4.1.1 to 4.3 to 4.4.2 (NE4). If you want the newer versions (NJ1 or NJ2) do them in sequence, do not skip any that are mentioned. Read the instructions on your linked page carefully. If you want NJ1 and then NJ2 they can be found in threads by enewman17, as can NE4 and maybe 4.3. I didn't provide the links so that you will hopefully read the pages carefully after searching and before downloading. Be sure you understand what you are downloading to flash and how it should be used.

Thanks **** I need to be extra careful before taking any step. I am going to collect all relesed OTA,s. By now I onky need the links for ota. Thanks

Flash MJB and NE4 from the site you linked to above. Then use enewman17's thread for the NJ1 and NJ2 updates. He also has NE4, in case you want to get all the OTA'S from him. (Downloads will be a lot faster) They've all been used many times. I'll try to post a direct link in a few...

I got this site having all ota, s . And is linked to the enewman17.
www.androidayos.com/samsung-galaxy-s3-stock-firmware-2/

Lol, I guess they thought they had to provide it somehow! It's a shame they didn't at least acknowledge enewman17 in their article there, but at least they direct linked to his thread.
Anyway, good luck! And if you have any other questions come up, let us know.
