[Q] Update to 4.3 from rooted 4.1.1

Could some one answer a few questions I have on how to go from rooted 4.1.1 to latest build. I have read and DL'd the zip from the "[LEAK] AT&T 4.3 UCUEMJ2 (Root & Knox versions)" thread and was wondering if the the rom can be loaded directly from CM recovery. Is the new bootloader required or optional?
Thanks

Have you checked to see if you can get OTA update or update via the latest version of Kies? I was able to update from 4.1.1 to 4.3 with 2 different pre-rooted i747s - one officially via OTA and the other by flashing the same zips you refer to via cm recovery so maybe that answers your question. Before taking the one-way trip to 4.3, however, be sure you are done messing with your phone at the older firmware including unlocking, if required, as you may not be able to go back.

I wasn't able to update via Kies. If I use CM recovery is there a specific order I need to install with and can I install the new bootloader with CM Recovery or do I need to use odin?

I'm not aware there is any Odin flashable file for 4.3 yet. You may follow the steps in the link below for manual update via CM...

You didn't say if you tried the OTA update? If you want to remain on stock, this is always the safest bet. If you are currently on official 4.1.1 you should be able to get this via WiFi with a valid AT&T sim card in your phone.

Me personally would avoid the official OTA update unless you're absolutely sure you want to keep it. Once you take the bootloader MJB you cannot flash any stock rom anymore unless you have an I747M then you can only flash the official 4.3.
I am on the MJ2 leak bootloader and have no issues, running S3Rx with the MJB modem phone runs great, if something happens I can simply flash anything I want to with Odin.

Exactly. I have also stayed away from the official 4.3. I have no idea why so many people around here just insist that their phone be on the latest update. Ok, the ones that had some major issues previously I could see, and yes you're going to have your exceptions whose phones will work just fine on 4.3. But all this 4.3 has done is create even more issues, with no flash-able firmware to go back to when something goes wrong. Some say there is no major reason not to update, but I say that there is no major reason to update, as most never give a reason to why they want to update. I just don't get it, other than these updates have become like new toys, just something new to play with.

shortydoggg thanks for your post and you actually hit the nail on the head. I can't think of reason I NEED to update, I just get bored and like to play. My warranty is up so voiding that isn't an issue and my 4.1.1 runs just fine, but by playing I learn so I like to play. 4.3 has a few nice features but if prevents the phone from being re-flashed then the risks most-likely aren't worth the benefits. I am just doing my due diligence, researching and asking questions. I really appreciate all the input and advice I get from forums such as this so I can make an intelligent decision.

If you really want to try and want it to be reversible you can use the 4.3 leaked MJ2 bootloader if you decide you don't like the 4.3 stuff you can simply Odin back to stock. But if you use the MJB bootloader you cannot.

I was running the same set up with MJ2 OS on MJB modem and the system was running fine until I recently flashed TWRP and SU to root and now the phone keeps booting to TWRP. I've run reset and reboot to system several times and even reflashed the system and modem files to attempt a reset but the same thing keeps happening - booting to TWRP. Will appreciate all steers on how I can rectify this.

You're on the MJ2 leak bootloader you can use Odin to flash a stock image on the phone if you can get it into download/Odin mode.

If it won't let you into download mode then format the internal SD card which should erase everything for the most part and flash everything fresh.

Thanks. It does get into download mode. Is there an Odin flashable file for the MJ2 and, if so, where can I find this? I'm wary about flashing an older ROM (e.g. 4.1.1) to avoid any further conflicts as I still have the official MJB modem or can this be done safely?
I've tried clearing the system and reflashing but it was the same result or perhaps I wasn't doing this the right way?

I have been told by very reliable sources that you can Odin to an older version safely regardless of modem as long as the bootloader isn't MJB or MK5 so I am pretty confident it is safe. At this point there isn't too much to loose.

Thanks. Just tried Odining to 4.1.1 but it failed, however. Would you recommend wiping the system in TWRP and booting to download to try again?

Odining to an older ROM is apparently not an option as this is isn't working. Thankfully, the phone is still booting into both download and recovery modes without difficulty so there is hope. I flashed CWM recovery via Odin thinking the problem may perhaps be with TWRP. However, the result was the same and the phone kept booting back into recovery mode rather than to the system. I also tried to see if was the bootloader so I flashed the MJB bootloader as well as reflashed the MJ2 system zip. The flashings were successful so, at least, it's unlikely to be a bootloader conflict but still the system will not boot.
Will greatly appreciate steers from the community on how to get the thing back working. n Thanks

Finally got it back up and running today. Cant be sure what really led to the soft brick but I simply wiped out everything in TWRP mode and then re-flashed the (MJ2) system, modem and kernel zips. This time it worked, I'd tried the same thing before but without the kernel. Now I'm back to the same configuration as before.

Would reinstalling from scratch help with performance?

The last two months my s3 has been performing terribly. I was on custom ROMs for over a year and made the switch back to stock which made my s3 feel like a new phone. But the last two months is a different story. I can't figure out why but things keep stalling and I find myself restarting my phone more often than I would want to
Anyway, I'm wondering whether reinstalling the stock ROM would help any bit

I went to stock 4.3 and it lagged terribly. I tried S3Rx and have fallen in love try it it may fix everything you don't like as it did for me. Look for it in the development section. There are still some things that don't work like bluetooth tethering. Look at it it is buttery smooth for me.

The stock / OTA 4.3 comes with the MJB version of bootloader and modem. The earlier leaked version of the Samsung/AT&T 4.3 ROM came with the MJ2 modem and bootloader. As long as you are installing to the correct device, the d2att, there should be no issues with the MJB modem, as long as it is good in your area. Some prefer the MJ2 bootloader over the MJB because the MJB will brick your phone if you try to Odin to an earlier version of stock. Yet some of the well known devs do not have an issue with the MJB bootloader. It is not until the last few days that recovery flashable version of the stock 4.3 became available, enewman17 posted it in the development forum.

[Q] On M919UVUAMDB. What are my options?

Hi Guys. I got my T-Mobile Galaxy S4 in May of last year. I promptly (as soon as I got home) rooted it. It is on Baseband M919UVUAMDB and I am currently running a December 9 nightly of CM11 (4.4.1) because any newer versions cause an issue with sleep and Wifi. If my phone goes into deep sleep with WIFI on, my screen will completely freeze, requiring a battery pull.
Now I've tried multiple roms running TW based on 4.3 (Guessing they're based on the M919UVUEMK2 OTA), but they all drop data.
Now that M919UVUFNB4 is out, I was wondering what would happen if I flashed to that (waiting for a pre-rooted ROM)?
Will I have the same issues? I love CM, but TW is full of features I like to use and would like to swap back and forth if possible.
What are my options? I no longer have any backups of any stock roms (I do have a 4.2 TW ROM backed up that had NO issues. I believe it was deodexed as well, if that has to do with anything).

The data drops are because you have the MDB modem. If you want to run those 4.3 based ROMs, you need either the hybrid MK2 modem (reversible, knox-free) or the full MK2 modem (not currently reversible, installs knox). The same situation would exist with the MDL modem.
See this thread for instructions to install the hybrid modem: http://forum.xda-developers.com/showthread.php?t=2546024
I don't know, but I'd guess the situation will be similar with the new KitKat release. To run the new ROMs properly, you'll probably need the newest modem (either a hybrid or full). I'm fairly confident that you'll run into the same issues if you're on MDB, but again, this portion is speculation. MK2 might end up being sufficient, or NB4 might be required. I won't be surprised if a hybrid MDL/NB4 modem pops up soon.

Just to be sure, I can run this via ODIN, since it's not MK2, it's MD, right?

I think so, but I'm not 100% sure. It looks like the same deal as the hybrid I've been using, and that I linked in my first response in this thread, just with the NB4 GSM modem and the MDL bootloader instead of the MK2 modem and MDL bootloader.
I never want to be among the first to flash new radios though. I hold off until I see a LOT of success stories and a lot of devs recommending them.

Flashable (TWRP/CWM) 4.4 NE4 Modem

Does someone have a "flashable" zip for the new 4.4 NE4 modem?

Not a good idea at this point. Unless yours already on NE4 firmware it'll brick.

I'm updated to NE4 and want to flash back to a 4.3 rom. I was able to downgrade but unable to get any signal due to not having NE4.
I just need the NE4 to flash to get signal back but not the whole OTA.

No it most likely won't fix WiFi, this is only for if you flashed the 4.3 modem as instructed in many 4.3 Rom threads, after having updated to the 4.4.2 firmware.
I believe the wifi issues you are referring to are kernel related. If on a 4.3 rom, flash the MJ2 kernel to fix.

Yeah Wifi is kernel issue. I've had to use the Ktoonez 4.3 kernel if I'm running a 4.3 ROM after updating to the NE4 bootloader.

so I'm currently on 4.4 NE4 bootloader and on an AOSP rom(AOSPA), will I be able to flash 4.3 kernel to fix wifi? I remembered some roms mentioned that 4.4 aosp rom only accept 7/1/14 and up kernels.. but forgot which

The kernel will have to match the rom. So if you're on a 4.4 rom, you'll need the kernel to be the same. Also, aosp/cm kernels are not compatible with touchwiz and vice versa. The MJ2 kernel fix I mentioned previously is only for 4.3 touchwiz roms. Im not sure about what you'd need to do for aosp though.

i've pretty much tried all the 4.4.x kernels and none of them seem to work :3

Probably best to ask in the thread you got your rom in then. I dont use non touchwiz roms so im not well versed with them and their requirements.
Generally, you should use the kernel included or recommended with the rom for troubleshooting.

yeah i know that, but thing is when i flashed the TW 4.4.2 from my previous post, the problem already showed up, I couldn't turn on wifi at all.
which happened to me before in the past and when i flash an AOSP rom, it fixed, so that was what i did, but just that this time it didn't work
and what pain me is that going back to stock will reset everything again...

did you manage to fix signal? im in the same boat and failed to flash NE4 (( i dont have a baseband and no modem will flash

Yep. Once you update to NE4 then you have to use NE4 modem from then on because the NE4 bootloader will enforce that.
Post #4 on this thread by DocHoliday77 provides a flashable NE4 modem zip that you can flash though CWM or TWRP and get your signal back.
Even if you use a 4.3 rom once you have tried or updated to NE4 bootloader, always flash NE4 modem.

I understand that this is an old thread, but I have recently pulled out my old S3 and see I am on FW Ver. I747UCUEMJB. I have seen the new lollipop roms for the S3 and they suggest flashing the NE4 modem/bootloader. Is this now safe to do? If not how would I go about upgrading my bootloader/modem?

Stupid question here but ... I'm already on NE4 but I Got the phone from a stranger. It works 100% but I don't know if anything was dine and put back or antrhiing. Its absolutely on NE 4. Can I reflash this in Odin without additional risk of bricking the device? I put lollipop on it and would miss it terribly

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.

Okay got Samsung phone info app.
Boot loader version -------I747UCDLK3
Baseband version -----I747UCDLK3
And please explain LATEST NE4 BOOT LOADER.
Thanks

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.)

1:- Okay I fully understood what I have to do to flash lolly pop . But confused a little bit . If I have original boodloader than it should be easier to restore my stock 4.1.1 . Backup (still not clear) .
2:- I am out of USA. The device in unlocked. I am using ZONG sim on it. So the question is can I still update the device via OTA.
Thanks

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.

Thanks men for quick response.
now I m fully confused. Don't know what to do. because I don't want to stuck on this battery enemy rom. (Aokp kitkat. Custom rom )
I am not clear about boootader version (PHONE INFO SAMSUNG APP SAYS ITS i747ucdlk3 ) but I know when got this thing. It was android 4.1.1 . Which I have back a backup. 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 . Iwill be very thankful to u people.
Again thanks

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!

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.
