updating bootloader and modem - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

i have att s3 i747. under baseband it says i747ucdlk3.
I want to install and experience with more roms, especially the lollipop nightlies. but they require an updated bootloader! Otherwise, my phone doesnt read the sim card. i have read so many threads on how to update the bootloader and modem/firmware, but half of the threads i read result in many people bricking their device! How do i update the bootloader properly? that is, without bricking my phone of course! should i do incremental updates? or jump from lk3 to the latest one? im lost on what to do, like i said so many people got bricked. can anyone help me out? it would be greatly appreciated!

i used this to get to NE4 with no problems.

Thanks I'll read up on it right now. I agree, I always read on forums first, which is why I found so many posts about how people had bricked their phones.
One question: did u use this to update from lk3?

Is your phone sim unlocked? If it isn't, you could flash back to a stock AT&T 4.1.1 ROM, unlock, and run OTA updates until your have the latest ROM on your phone. This approach requires more time but it is the simplest and least risky in my opinion.

So basically you're saying to flash back to unrooted stock. And then keep using att updates until I get to the latest one, and then I should be on ne4 automatically?? Not sure if I'm understanding this correctly.

Yes, flash back to stock and keep running ota until you hit the latest release.
If you have warranty left on your phone, updating, rooting, and loading a custom recovery will change the warranty bit from 0 to 1 which voids the remaining warranty.

K will do when chance the chance. Btw. Isn't there a requirement to not go past a certain firmware if I wanted to revert back to stock or else it'll brick? I thought it was if I go past 4.3. Any ideas?

You will have no choice but to flash to 4.4.2 bootloader and modem if you want to run the latest d2lte ROMs.
True, once you are on 4.3 or higher bootloader, you cannot go back to stock 4.1.1.

Isn't the 4.1.1 bootloader lk3? Cuz for some reason I'm on a 4.4.4 ROM with a baseband that ends in lk3....does that mean anything?
Sorry guys I'm clueless when it comes to modems and bootloaders and all that stuff. Thanks for these replies btw.

Some kk roms will run on a 4.1.1 bootloader while others will not. I know some of the newer cm11 roms will work but you will not have any signal with older modems and bootloaders.

i had read of some people have to use ktoonz kernel to get wifi , but that is usually in the OP.
thank you once again @audit13 for coming to the rescue. i am now M8 and losing what little i747 now-how i had. lmao.
"all i can really do , is stay out of my own way and let the will of heaven be done"

So since I'm on lk3.. I should still be able to flash black to 4.1.1 stock via Odin and then use the ota right? Or should I flash back to 4.3. Which one is the safe option? Im thinking about using the ota option mentioned earlier in this thread.

If you are returning, you must use Odin to flash the stock rom. No worry we are all noobs, some just know more than others.

So by flashing a custom 4.3 knox free....I can still odin back to stock 4.2, triangle away, unroot and be good for warranty issues?
In other words theres nothing to worry about with flashing a 4.3 rom so long as I just go back to 4.2 and use the correct procedures to do so......with all the scattered info I was kinda concerned about trying 4.3
If you are planning to return it, why not flash the OTA version of 4.3 via Kies just before you do and be done with it?

I am confused about warranty, knox and all that...I have been around a long time and have owned all the gallaxy s phones and flashed em all but this new ota has me concerned....atleast with 4.2 I "know" ill not have any issues with warranty returns.
I dont have plans to return it....im thinking into the future a bit....
....I guess what im asking is....if I go to 4.3 can I easily odin back to stock 4.2

Yes. Flashing a custom 4.3 rom through recovery (not odin) without the knox bootloader is like flashing any other rom. You can go back to 4.2 for warranty purposes just like any other time.

Upgrading to T-Mobile 4.3 via OTA

Just checked for updates as described in other threads and it found the latest 4.3 update. I have read both positive and negative responses to the update. Some found things they used in 4.1.2 that are being taken away. Some like the new features in 4.3. It will vary from person to person whether the ROM is better for them or not. Fact is, all devices (current and future) are moving forward.
Should I just install the update? Should I make a copy of my current setup with one of the recoveries, then odin back, and run triangle away?
Strange. I went ahead and updated. Even after doing two complete resets, I still have SU app from 4.1.2. I guess it carried the program during the upgrade process?

it basically dirty flashed the new update over your 4.1.2. I honestly didn't care much about the KNOX boot loader since my warranty is already over. but, I find not having to flash devil kernel so much easier w/ less lag.

Hopefully someone will develop something that resets the KNOX counter. Triangle worked for 4.1.2, but does not work in 4.3 for me.
BTW, what 4.3 ROMs do you like, since we have the new bootloader? I just installed TWRP and trying to decide on a ROM.

theyre for different companies i believe. as how ours (T889) also has a T889v ( i think thats the right letter) version as its for a different conpany. I installed using the ATT one. there's really no difference because you're just going to flash a tmobile modem over it.

yes the boot loader is locked. I don't believe there's a workaround it yet. but I'm even sure. you can scroll around through the threads and see if there is. what I did was just update it anyways and tripped my KNOX boot loader to ox1. I didn't have warranty anyways so I'm not tripping over it. and then I just rooted it, flashed cwm and started to flash ROMs.

if you're going to end up on aokp, you should just stay on the 4.1.2 boot loader. the update to me is really only for TW roms because the stock ROMs are working just fine w/o the new boot loader.

Thanks in advance for any help

Nop, you can't. If you need 4.3, you definitely need bootloader update. Atleast to MJ2.
CM require certain bootloader updates for things work perfectly. Check their site. Here they clearly said need an update to bootloader. http://review.cyanogenmod.org/#/c/37696/.
One thing, read before flash. yeah, time matters, but when bricked; again time matter for new device with lot of hard earned $$$.

If you ever need to return to stok rom; stick to MG2 for safe. But make sure odin won't update your bootloader afterwards.

Yea, stay away from MJB. My phone just like others works fine on MG2. 4.3 and MJB has only caused headaches around here without very many answers. Of course you are going to have exceptions whose phones are just fine with MJB, but you will have a lot of those headaches if your phone is not one of them.

[Q] Galaxy S3 downgrade from android 4.3 to 4.1.2

I have a T-Mobile Samsung Galaxy S3 (SGH-T999) and I made the mistake of allowing an upgrade??? to android 4.3 which has been very unstable for me. T-Mobile, Samsung, and Google all say that there are no updates to 4.3 and I can’t downgrade, so basically I’m out of luck.
Can I downgrade 4.3 to 4.1.2 without bricking my phone and hopefully without voiding my warranty? If so, please give me some instructions. I downloaded Odin 3.07 and firmware: root66_TMO_T999UVDMD5.7z. Thanks a million.
I don't think it's possible to downgrade anymore due to Knox. There was a thread talking about it

if you flash the root66 of the md5 firmware via odin after you have already upgraded to 4.3 you will HARD BRICK your phone. Taking the 4.3 ota updates your bootloader and flashing anything other than 4.3 in odin will wreck your life.
You need to download the root66mjc firmware here:
http://www.androidfilehost.com/?fid=23212708291682181
And flash it in odin. Then from there install a custom recovery and download a rom of your choosing and the compatible modem. I recommend you download the md5 modem. Then you're gonna wanna boot into recovery and flash the rom and the modem only (kernels are ok of course) JUST NO BOOTLOADERS. I don't even know if you can do that in recovery but trying to mess with the new BL will brick your face I mean phone.

I was referring to the 3 persons who responded to the OP's question similar to yours. @jtl_777's response is pointing to the 4.3 Firmware.
Its more implied in this thread than stated matter of factly. This thread is several months old, and I know your question has been asked countless times in many different threads, much more recently than in this one.
I suggest you read the stickies in each section. Just by doing that you will find all firmware and modems and more. You will also find that the answer is no, you cannot downgrade your full firmware from 4.3. And you never will be able to.
If your having problems I suggest flashing the latest 4.3 build via Odin, then factory resetting. Start over clean with minimal restoring of backups (only the essentials).
Every time an update comes out there are people who have problems. The majority are solved by doing what I just said because most bugs are caused by using old data created by old apps on the new build.
Even if you could downgrade, chances are youd run into even more issues and still have to factory reset.

thanks but I read online and some youtube videos showing that people have gone from 4.3 back to 4.1.2, just trying to make the phone the way it was before any updates were done and wondering if anyone knows the proper steps without bricking the phone.
They probably just flashed a rom. It is simply not possible to downgrade the firmware though.

great thanks so much for your help, can I flash the recovery via odin mobile app or is it safer to do it via pc?
Safer via PC.
It is possible via Mobile Odin. But that's one of the partitions I don't want to mess with when Phone is Booted/
If you know how to use Mobile Odin then it should be fine. I agree that its better to use pc odin if youre not familiar with Mobile Odin. However, it actually doesnt flash the recovery while booted. It flashes the flash kernel which is MO's temp recovery. It then boots to this and flashes. (So, perseus is right in that regard. But I personally love Mobile Odin and find it extremely useful and consider it safe unless you are brand new to all of this).
In fact Mobile Odin is another way you can flash 4.1.2. Itll flash the firmware, but only the system, kernel, recovery and modem. (I didnt bring this up previously because I didnt want to confuse, or go too far too fast).
If youre thinking about flashing recovery via MO, though, you can also instead just flash the rom you found. No need to flash the recovery unless you just want to. Put the rom in the update.zip slot and itll flash just fine.
If any of this is confusing, just stick with the original plan for now. The rest will come easy if you dont rush things.
One more thing, while you can usually update stock without wiping, you may find you have to factory reset after downgrading as the old system was not built for using data created on a new version.

thanks for all the help.. had to do the wipe since it kept showing the samsung logo but after that it booted just fine.

[Q] T999v - TWRP (2.7.1.0 or older) “NO OS Found”

Hi All,
I have S3 T999v – Wind variant running on stock 4.4.2 , overall I hate this kitkat experience...
My issue is whenever I try to flash custom recovery TWRP (2.7.1.0 or older), it installs but when I try to take backup it shows nothing to take backup of (no System , no EFS etc....). When I try rebooting it gives error “NO OS Found” I am able to proceed anyways and it starts up phone fine.
Can anyone tell me what could be the issue here??? I wanna downgarde to either stock 4.3 or to install custom liquid smooth 4.4.4. but would prefer to take a back up just in case.
BTW my phone is rooted , rooted it with towel root.
Also can I flash T999 (t-mobile) based recoveries onto my T999v ?
Would appreciate your help :good:.
Thanks
I recommend using d2tmo recoveries over d2can. More roms will be flashable. And you can use any rom here in our forums.
For now, try using either cwm or philz recovery. Youre experiencing a known issue that I believe is related to the hardware revision. I keep hoping to attempt a fix, but just havent had time yet. But for now, one of the other recoveries should work for you.

Thanks buddy, yup CWM worked :good:
but why cant we downgrade to 4.3, i though it was that one cannot downgrade lower than 4.3 i.e. 4.2. in not possible now!
Knox. They prevent any downgrading to protect against tampering with Knox secure containers. You can't downgrade anymore, period. Anything beyond 4.3 or with Knox will be this way from now on.

Yeah just like doc said, if you're on 4.3 firmware you can't downgrade firmware to 4.1.2, or if you're on 4.4.2 you can't downgrade to 4.3 or 4.1.2.. Anything lower than your current firmware is a no.. You can only flash equal or newer firmware
