[Q] Update bootloader?

Device: AT&T Galaxy S3
Rom:[ROM] AOKP(Jellybean 4.2.2 )Task650 (5.14.2013) (AT&T)
I wanted to update to the devs newest release but i need to update my bootloader in order to do so and ive never done that so if you have any advice or something i can read up on that would be awesome

I "I made some ODIN-flashable files that contain the bootloader, RPM, TZ, and baseband of the stated versions , so that people won't have to go completely back to stock TW. It's intended for those not on the necessary bootloaders yet so that they can flash future CM builds. Put them into the PDA section in Odin and flash away.

http://www.mediafire.com/?74b1e321p537f5d
Note: They're untested, but should work as intended. Tested by fellow users, works fine. Please flash at your own risk!
EDIT: Threw up Mediafire mirrors, since d-h.st seems to be down randomly."

it's pretty simple and harmless. took me less than a minute. Domoo has linked you to Jiangyi's post on this topic, which includes his downloads and instructions. cheers

well that was easy thanks for the help guys!

Flashing a bootloader is not harmless. It is one of the few things that can hard brick this device.

Because it was a good warning. Flashing a ROM should not be taken lightly and flashing a bootloader should be done with alot of care as it can brick your device to the point of needed a JTAG to fix.

yes, bootloaders are very serious business. just because this bootloader flashed without error does not mean that the operation is not serious. take note, OP.
zelendel, everything in context.

As long as your bootloader ends in a dlk3 then you have the most recent one.

You can check your bootloader version by opening a terminal and typing:
Code:
su
getprop ro.bootloader

I747UCDLK3. Most current. Got it from At&t recently...I am surprised that they did the update. I didn't let the phone OTA either. Honestly, though I didn't look, flashed it out of the box.

I'm on Rogers, with bootloader I747MVLALH1, haven't flashed anything since mid April. Should I use ODIN to flash the I747MVLDLK4 bootloader? I was planning on updating to a newer CM10.1 nightly and just saw that I needed a new bootloader to do it properly.

@ Everyone
I don't have time to screw around. I just tested this and it works fine. I just would've rather bricked my device rather than yours. That's why I like to test all links for these types of things before I promote them off to you guys..
1.) Go here (above posted thread link)
2.) Put phone into download mode and then open Odin.
3.) Choose the PDA slot and then select the correct file for your device (AT&T is LK3)
4.) Hit start and wait until its finished.
5.) Done
5.) Remind me that I shouldn't be trying to do this from my phone. All it does it piss me off.

[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
Maybe you should check it out.

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.

full steps?
so does anyone have any full list of steps and links on where to get the modems and all to downgrade 4.3 with knox down to 4.1.2

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.

so do i just download the below file, extract and flash via odin then do a wipe via recovery? If not can you please explain how to go about this so i can have 4.1.2 running on the phone

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.

If I remember right, once on 4.3 you can no longer use the free unlock method. You will have to buy a code online. If you have a T999, you can try flashing the 4.1.1 modem and see if you can do it though. You wont get any signal if you are on a 4.3 rom until you flash back to the 4.3 modem btw.

You dont need to be rooted, but you do need a custom recovery (TWRP or CWM) in order to flash the modem. I never made any odin flashable packages for the modems, only recovery flashable.
Just so you know, flashing a custom recovery will void your warranty if its still valid and you care about that.

Thanks bro, I don't care about warranty.... So all I have to do now is flash a recovery then flash the modem, hmm wonder if anyone has ever got it to work like that before tho.... If it doesn't tho can u recommend a cheap unlocking site please

All I remember for sure is that on 4.1.2, samsung patched against this unlock method, but we were still able to flash the 4.1.1 modem and unlock. In 4.3, you cant use an older modem or youll get no signal, but Im just not sure if you can still use the free unlock method that way.
Ebay had several very cheap options at one point. Also, http://gsmliberty.net has/had(?) a promo where if you posted a video of yourself unlocking using their method they would refund you your money, essentially making it free. Not sure if that is still valid though.

There were several mentions of specific sellers that only charged a few bucks in the unlock thread if you want to dig in to find them.

Any 4.1.1 modem, as long as its one for your model device. If you wanted you could see if flashing a 4.1.1 or 4.1.2 rom would make a difference, but as before, I kinda doubt it will.
When we were updated to 4.1.2, and found that the unlock method was patched, all we had to do was flash an older modem. Didnt matter what build it was from.

agree

updating bootloader and modem

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!

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.

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.

After downgrading the modem, I always recommend reflashing the latest rom from sammobile.com in Odin followed by a full wipe in stock recovery.

Both have the same files.
1. Unzip and flash 4.2.2 modem with Odin(CP Button).
2. Open RegionLockAway and follow the instructions.
3. Once RegionLockAway finish flash 4.4.4 modem.
It's better if you're in stock(if you wanna be sure nothing happens).
