Hey. So I have a note 2 on at&t. It was on 4.3. I used odin to downgrade to 4.1.1, then factory unlocked it and all was well. I tested with tmobile sim and it was on tmobile 4g and able to make calls using tmobile. I then went to update the version (I read once its unlocked it can be updated) Now, it gets stuck at "samsung galaxy note 2" when booting up and wont go past it. I tried to odin it again and successfully installed 4.1.1, but still wont get past samsung galaxy note 2. have disconnected phone and tried to boot up using vol+ (+) home button (+) power button, but nothing......PLEASE HELP
thanks

I don't have a Note (I have the GS3 on TMO). Do you have any idea if the Note 2 has the same issue that the GS3 has, where with the 4.3 update you get a new locked bootloader that prevents you from going back to anything earlier than 4.3? That's the way it is on the GS3. I guess if you were able to actually boot up and make calls after you downgraded back to 4.1.1, then that must not be the case.
In any case, you're getting stuck on the boot logo when you power it on? Can you get into the recovery at all? Do you have the stock recovery or a custom recovery installed? Have you tried clearing cache/dalvik and fixing perms? That often fixes things for me when I'm stuck on the boot logo.

I start to wonder if people research before doing anything.
To say again. You can't downgrade. You have Knox. You possibly tripped the Knox flag. Reflash the 4.3 stock ROM. If that fails, It's most probably eFuse, if It's 4.3.
(Basically, eFuse messes up your phone aka bricks You phone aka @#%& it up.)

You're right. The locked bootloader messed those who didn't research about it's life's real bad. 4.3 supposedly has eFuse in it, which FU*CKS your phone. I read it up on the Samsung Knox website, and it said that eFuse "rewrites a read-only part of the phone, resulting in a unusable phone." If u triggered that, it'll be a hard brick, (in my knowledge)
Knox itself is irritating. The Knox Warranty Void counter, which max at 1, is unresetable, (even with JTAG, will brick if h try) so your warranty is *poof*

I did a fair amount of research before downgrading. In fact I didn't want to downgrade, but I did want to unlock it. It is unlocked and it's running on 4.1.1. So when you say that you can't downgrade, you mean you shouldn't downgrade cause then you will be stuck with 4.1.1?

When you were on 4.3, was that an OTA update or an ODIN flash of a stock firmware? Or did you just have a 4.3 ROM from the forums that you loaded (AOSP or rooted stock based ROM with Knox, etc., removed) with TWRP or CWM? Supposedly from what I've been reading if you take the 4.3 OTA or ODIN flash the stock 4.3, the bootloader gets updated, as Irwenzhao mentions above and I've experienced, where you CAN'T downgrade again to 4.1.2 or earlier. I believe that just means you can't go back to a fully stock pre 4.3. I THINK it just means you can't ODIN back to a factory image earlier than 4.3, which is what I experienced. But with TWRP or CWM, I believe I can still load other ROMs at will regardless if they are pre 4.3 or not.
yeah, that sounds kinda like the same thing I have come across. 4.3 was OTA and downgraded to a stock 4.1.1 ROM. Guess this triggers KNOX cause now KNOX WARRANTY VOID is 1. which once that is triggered, you cannot go from a non KNOX version (4.1.1) to a version that has KNOX. My question now is does that apply to just the stock firmware? Would ANY of the ROM's created by the devs work?
There were some posts in the unlock thread that people were able to go from 4.1.1 (after downgrading) back up to 4.3. Just trying to figure out how that would be the case? Could the knox warranty flag not have been set for them?

Just to make it clear, Knox is a bootloader, which means u can flash anything that's not a bootloader, but your warranty would be history. Flashing anything trips the flag, even 4.1.1/2 stock ROMs.

Truthfully, that doesn't clear it up. Do the stock firmware through Kies or ota include a bootloader and that's why it won't install? Thanks
Flashing the stock firmware through kies, ODIN, or the OTA update will update the boot loader as far as I know and will ruin any chance of returning to stock and void your warranty. As long as you don't want to do that, I don't think it's too big of a deal.
At this point, I couldn't care less about the warranty. I would think it's expired now anyhow. As long as I can flash ROMs and boy the phone up and use it. I'm happy.

I have a Samsung Galaxy S III Verizon (model: SCH-I535) and its currently updated to its latest firmware, I was trying to downgrade/ root it but it wont work it keeps failing on Odin. My purpose was my main question, is it possible that I could flash a stock SGH T999 firmware on my phone? I would be really grateful if someone showed me a step by step process on how this could be done.
And recently I cant do anything with my phone but officially upgrade it. I think when i upgraded its firmware the security suddenly got tighter, can someone help me about this?
My plan was suppose to be (knowing that 4.3 and the latest firmware on my Verizon prevented me from doing anything): to downgrade to a lower firmware version, then flash the T-Mobile stock firmware.
hey guys, so im sure many have tried to put cyanogenmod on a VZW Samsung Galaxy s III with 4.4.2 OTA on it. but couldnt. im really looking to put CM11 on it. im very much so new to rooting, and flashing roms, but i already rooted my device, and flashed the stock firmware back, due to not having a CWM back up and getting "system software not authorized by verizon" warning.
so my question.
can i downgrade my firmware from 4.4 to earlier to have an unlocked bootloader without bricking it? do i need to go to 4.3 and then 4.1.2?
because before 4.3 it had an unlocked bootloader.
I really want CM because i cant stand touchwiz anymore. thanks guys . help a newb out
oh and. should i use towel root? or another rooting method
Your now on the locked bootloader and you cannot downgrade to another firmware. You can root with towelroot but that's truly about all you can do

Good afternoon all if anyone could please help I'd greatly appreciate it!
So I just bought a Sprint Galaxy S5 from ebay with the assumption that with some customizing I'd be able to get the phone domestically unlocked. I got the phone and it was already updated to 5.0 Lollipop so I followed this tutorial to get the SSU.apk to actually work
http://forum.xda-developers.com/spr...locking-sprint-galaxy-s5-g900p-t3085624/page2
After a lot of time I was successful at rooting the phone and was able to downgrade to 4.4.4 but the tutorial calls for 4.4.2 but it seems that 4.4.4 was the only fw that would successfully install.
But now here's the problem I was able to obtain the domestic unlock code through Sprint but now the activation/update app doesn't work and doesn't open automatically the way that the reps said it would,. I've tried to reset stock through Kies but Kies doesn't recognize the phone. I've also tried to use Odin through out this process not only to reset back to stock but also downgrade the fw and the modem. The really annoying part is that small PDA/AP updates and installs work fine but when I try to Odin the original tars it always fails 100% getting a "sw rev check fail aboot fused 2 binary 1 " error on my phone.
I really don't know what to do at this point, and it seems the error is associated with a soft brick but the device still powers on and boots.
I thought this would be a pretty straight forward process but I've hit the wall and am losing my mind, I need help!
P.s. I flashed 4.4.4 fw with CWM and the device is still rooted
Thanks
Hi Guys I have a SM N915P and i got it updated on 6.0.1 but i want to iflash 5.1.1 on it. i downloaded the firmware from sammobile but i cannot just flash it Odin Says Auth Fail.
