[Q] SGH-I337 AT&T Bootloader Unlock - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

After reading up a bunch it appears that even though I've successfully rooted my AT&T Galaxy S4 running NI1, I will not be able to unlock the bootloader and need to use safestrap and simply be limited to TW based ROMs. LAME!
Honestly, I don't care about voiding the warranty by tripping the knox sensor. What I would like to find out is if anyone has successfully flashed a previous build that has an unlocked bootloader so that I can put a custom recovery on and flash AOSP roms. Again, I know it will void the warranty. Don't care. If anyone could point me to a thread or explaining the process that would be cool. I've been searching for hours and have come across people asking the question but they just get met with "you'll void your warranty" bs.
If it can be done without bricking the phone I'll do it.

It can't be done. Qfuses are blown. It won't brick your device trying, Odin will just fail. But it's not worth the time trying because it won't work.

Sorry, can you clarify? You said "it won't brick your device trying", but it sounds like from the other parts of your post that you are saying it WILL brick the device.
What I hear you saying is that because of a "Qfuse" if I flash a pre-MGG stock release of the AT&T S4 firmware using ODIN on a rooted NI1 firmware then the device will brick. Is that accurate? I assume you know this because someone tried or is it theoretical? I don't ask because I'm skeptical but simply because sometimes people repeat things based on what someone else said rather than actual tested results.

Part of the reason I'm asking is because all the posts that I'm looking at people are saying flashing a pre-MGG rom will result in the knox register being changed to 0x1. I don't really care about that. What I want to know if warranty void or no, will it work. The QFuse posts don't seem real clear either.

A brick is when you're device becomes completely inoperable and unrecoverable. That will not occur if you try to flash the mdl firmware. But, the mdl firmware will not flash onto your device. Doesn't matter if you don't care about voiding warranty or not. It simply won't work, ever.
And by the way, there are no AT&T i337 bootloaders that were unlocked. There were just two that could be exploited with Loki to flash custom recoveries and kernels.

Should I update or not

I am worried that the samsung knox will ruin my device.So should I update or not.What if I got bored of touchwiz and wanted to flash a new rom
Does updating mean I will lose the ability to root and flash forever?
If you search the forum you will see someone already posted a rom with the knox striped. Wait a bit longer and I am sure more versions will be coming.

as far as i did understand that, it is a question of the new bootloader, where a knox flag shows your flashing orgies, which cannot be resetted at the time (no triangle away can help us so far)...so if you try to get away from the original firmware, you raise the counter and void your warranty...well, if you had one
anyway, if you have no warranty, you can show your backside to knox. nothing will happen, but a flash counter shows what you were doing...
please be careful, of course you can brick your phone with flashing, as always, but this will not have anything to do with knox!
EDIT: the only thing is, there is no possibility to downgrade the bootloader by now! so, you cannot simply go back to 4.1! but you can of course flash 4.3 custom roms...
I still don't get why Samsung has this Knox thing. As far as I know, here in the EU, rooting and flashing ROMs does not void the warranty unless it is proven that the malfunction came from the owner messing with the software. So, having Knox raising a counter or flag the device or whatever, is pretty useless, at least here in the EU. We already have the flash counter. The only advantage may be that with Knox, there is no way to conceal the precious flashes and that we can claim the warranty when we DID messed up the phone somehow, because if we didn't, the warranty is still active.

Not sure about n2 but with n3 physical damage, in the form of a broken efuse, is actually the result of tripping knox. So even under eu regulations, the warranty is void once knox is tripped.

What a cheap trick they made. Since modifying software does not void warranty, they make a little piece of hardware get damaged so the warranty gets void even though that the so called e-fuse is non-essential (I think) for the smartphone correct functioning . Wow, that is even worst that what I was thinking. Samsung really messed up this time, what's the point of having an Android then? So, after all, we people from the EU, can't get away with our flashes and customizations...
Thanks for the info, btw.
Stick to 4.1.2 and enjoy mindless flashing of custom roms.
Let't go!!!

Knox has been deleted at the DN3 Rom.
Anyways AFAIK you flash DN3 Rom from Stock 4.1.2 the Bootloader will be still the old one and you have to use the wifi fix.

yeah agree totally on this,. they make sure you only have 1 way go to up in version of rom without able to go back down to older rom by locking it with knox,. it is very cheap method samsung is using this time, kind of what's else is the point of not able to flashing all fancy custom rom ?
Ditto Note 3 is awesome. They just released v3 and works great. I was on 4.1.2 for the longest time then updated to 4.3 official release but Knox was so annoying I have decided to go for custom rom and I am very happy so far.

1. Yes Flashback should be possible.
2+3. In any case do a backup of your imei, there are various possibilties but you need root.
After several days of sheer frustration with 4.3 constantly rebooting, freezing my phone, causing the "black screen of death", numerous force closes, broken apps and producing many permission related errors which can be seen in logcat, I downgraded to 4.1.2 this morning and haven't had a single issue in 12 hours. I have no good reason to ever change my firmware from 4.1.2. It's solid as a rock and trouble-free. Maybe if stability improves on 4.3, I may try it out again in six months.
Sent from my GT-N7100 using Tapatalk
I am not eager to flash, but because I have a gear now, I updated to open Asia mj5 4.3.
Rock solid until now, gear works 100%.
The only worry I have is future updates, because mj5 is a "leak".
But, mj5 is stable for me, although it seems a bit slower at times as the 4.1.2
Never rooted, standard all the way.

Guys, I don't think KNOX e-fuse is there to void the warranty or for Samsung to know if you flashed your device or not. KNOX e-fuse is there so that you know if the phone has been messed up with if you actualy use KNOX. This is for the COMPANIES that need enhanced security etc. And for this security there must be a way to tell if the device has been messed with. For most people that don't use company phone (and for majority of those who do) KNOX is not interesting because they don't need it. But I understand why banks and other institutions that demand security would need it.
So it is no cheap trick by Samsung to get to void ordinary user's warranty, it is a security measure which only some companies will use.

[Q] Just bought an S4 and did the 4.3 OTA and have Knox, should I return the phone?

Hi everyone, I have about 7 days left on my "14 day return policy" from the Sprint store. I love XDA and it's been a HUGE help to me in the last few years. I like the phone, it's pretty snappy, and the camera is great. But I can't use a phone without root (who can??) and eventually Samsung will stop pushing updates to this phone so I'm going to need to flash custom ROMs (cyanogenmod did wonders on my last phone, the Galaxy S1). I also know that I can't mount SMB or CFS shares without flashing a kernel that supports it and I'm not sure if the S4's official firmware supports the ability to do so (which I believe requires root anyway, so I guess I answered my own question.
I have a couple of questions about the S4 that I'm hoping someone who has experience can tell me about this.
1) Can I root using VRoot and NOT trip the Knox warranty bit?
2) After rooting, can I install a recovery (I've read that Philz CWM recovery works but can't find definitive answers on this).
3) Should I even care about the Knox software?
I don't need to use the phone in an enterprise environment, but I also don't want the phone's bootloader locked to Samsung firmwares if it means I won't be able to install custom FW's or kernels.
Should I return the phone? I'll pay the $35 restocking fee just to save myself from having to deal with Samsung's (and this my opinion) bonehead move of abandoning its developer userbase.
Any and all responses would be appreciated. Thanks for reading and helping!

I am not worried about the Knox bit. Mine is tripped and it's not preventing anything, AFAIK. I can still install Sammy firmwares, ROM's that are at the correct version/level, mods, apps, etc. It seems it's really only a flag for enterprise users. I agree it kind of sucks, and I'm not a fan of it, but it doesn't seem to be causing any real harm at this point warranty or service wise. Some say it may prevent Samsung from honoring the warranty, but I'm not sure that's true, based on reading the forums.
As far as Samsung stopping pushing firmwares to this phone, that should be a long way off since this is their flagship smartphone at this point. It's a great phone and I've been very happy with mine, which I got the weekend they were released. Rooted, stock rom, hotspot mod. So much better phone than my old HTC Androids!

This is just a thought... but... check your phone, when I got mine not too long back it still came with 4.2 on it. If yours still has 4.2 you wouldn't have to worry about knox as long as you didn't take the OTA. You could root it and rom it all you wanted.
Yes you should return the phone. That way you **** all the people who return their phones for legitimate warranty/insurance reasons with higher costs.

I haven't done any type of rooting or modification to the phone yet. That's the reason I'm asking, I haven't tripped the counter. I'm just aggravated by not having root and being able to remove this crapware. I wouldn't be ****ing anyone. Please don't be a ****.

This is great news, can you point me to the tool you used to root the phone? I've read the Chinese VRoot method doesn't trip the counter, but installs "Superuser" which can subsequently be removed and replaced with SuperSU. I think using SuperSU and something like DroidWall to monitor the device to make sure nothing fishy is going on will help us determine whether or not VRoot is really malware (I've read comments saying that it's some kind of spyware but I'm not sure of the technical prowess of those commenters).
What recovery are you using to flash custom ROMs?
And as asked in a previous post-- Did you root before taking the OTA? Or did you take the OTA and do you see the Knox Warranty Bit marked as 0x1 in the stock recovery?
Thanks for the replies, appreciate all the info guys!

Dont use vroot. Until some dev can pin point what the chinese root method actually does. And if your on 4.2.2 your ok but once ota to 4.3 then you have knox bootloader meaning you cant downgrade firmwares. It wont stop you from changing kernels and roms. Knox flag just voids your warranty with samsung but if you have insurance with sprint they can care less about it tripped. I updated to 4.3 and tripped the knox amd I havent seen no problems really. Btw please make research this has been talked about lately too much.

Yes, my Knox bit it tripped/set. It is 0x1 on the download screen. Can't view it in recovery. I just used CF Auto Root after going to 4.3. Should be easy to search and find that thread. I'm on the stock rom with tweaks.
Using TWRP recovery, but I've tried several, including Philz and OUDHS. It seems Philz is the flavor of the month, so you might want to go with that just to be safe.
I did not root before taking the OTA. I don't think I'd try it that way. I was rooted, but went back to stock to take the update. If you get back to stock, reset the custom bits on your download screen (triangle away and RTN's seem to do that, but might have to do more than one), recover your apps/data and then take the OTA, it should be the most sure fire method. Then root, custom recovery, nandroid backup and play from there.

Thank you, I plan to just use CF-Auto-Root to root the phone. I'm starting to care less about the Knox bit getting tripped.
I came across this post by rawintellect that seems to have everything I'd need out of the phone, rooted/deodexed MK2 with all the bloat removed, BUT it says in the description that the Knox Bootloader is removed *EDIT: After thinking about the statement some more, I think he means the Knox bootloader is NOT included in the rom, but this raises another question, can I install it on a phone WITH the knox bootloader?), so I'm afraid of attempting to flash it because as I understand it, it's impossible to replace the knox bootloader.
Here's the post: http://forum.xda-developers.com/showpost.php?p=48516106
This individual seems to have gotten everything working: http://forum.xda-developers.com/showpost.php?p=48516106&postcount=88
Do you know if anyone is able to flash Philz through Odin successfully on the MJA/knox bootloader?
I took mine back after I took the OTA. I was honest about why I was returning it, that the firmware introduces restrictions and annoying features (I cited the multiple WiFi security warnings in particular) I was not willing to accept, and the independent store I was dealing with gave me an exchange to a new phone with 4.2. I first asked if they could downgrade the phone to 4.2, including the bootloader, they researched that option, finding it impossible.
If they had not given me the exchange, I would have picked a different color and done it that way.

Picking up an "un-used" Sprint S4, what software/baseband/bootloader is ideal?
Going to meet person at a Sprint store so I will confirm ESN is clean of course, but person claims phone has not been used so my question is what software/baseband and bootloader is ideal to have?
Basically I want to see if phone is pre Knox and if so I am not going to update it until I read up on here, but I am not sure what versions are pre knox.
Phone will be for my wife and I will be rooting it and I need it to be able to have the hacked/free wifi tether or built in tether, but I will want her to have the latest stock rom.
Thanks
MDC, MDL, and MF9 are the pre Knox. As these are 4.2.2 and below. MJA and MK2 are Knox being 4.3.

is there any advantage?
You can open the hotspot on any version. All the knox bootloader does is trip the warranty flag so if you root it you want be able to get warranty service from Samsung. In my opinion, the newest firmware just works better than the old. If you're getting a good deal on the phone then it shouldn't matter. Just know that if you root it which you will need to do to hack the hot-spot then you do void the Samsung warranty.

I thought there was a difference w
between the Knox warranty and the Samsung phone warranty for any malfunctions or such.

I did a good amount of reading last night and what I think I have learned is the following:
Rooting MK2 doesn't always stick and I must be using Philz recovery on 4.3, some say CF auto root does work on MK2 but some say it does not. Been reading that there are some wifi issues on 4.3 after flashing/rooting/recovery but not sure exactly what the issue is. Also, not completely sure if I can flash the MJA hotspot mod on MK2, I think one person said it worked but that is all.
I bought the phone used off of CL so I really don't care about warranty because I have no proof of purchase or even original purchase date. I think the guy had his receipt but he did not give it to me. I just don't want any rooting headaches once on the knox bootloader which I have been reading there are a lot of.

Mk2 roots just fine if you use the newest cf-autoroot files. Sometimes you have to install superSU from the play store afterwards but much easier than HTC. There is an MK2 hot spot mod. It is in post #337 in the hot spot mod thread. Also you can use twrp or philz recovery. Just make sure you are on the latest one. As far as WiFi issues. Some experience it some don't. I'd you do them just reinstall the mk2 modem with Odin and it should clear up. Good luck.

Thanks for the info, I am thinking that I may just take OTA to MK2 or flash to the latest (I think I just saw a thread that someone posted a flashable Odin file that is just like getting the OTA, Knox and all) and not care if I trip Knox or not.
The only possible reason I may not do this is if I can get insurance on this phone when I activate it on my wifes line (this is why I played the no flash count game on my E4GT). I am not sure if I even want the insurance but if I do then I have to worry about Knox.
Thanks again for the help and especially for the post number for the hot spot mod, that is very helpful.

The warranty flag is for warranty, specifically the Samsung factory warranty. It will not affect your ability to use TEP, Assurian, Square Trade, or the Best Buy insurance. Rooting and custom roms have always voided the factory warranty on all manufacturers. In the past, we usually had a way to reset the phone and hide the fact that we rooted it. The Knox flag at this point can not be reset so now Samsung knows you rooted it. As long as you never need a warranty repair you are fine if its tripped.

[Q] What If I don't care about tripping knox?

I have a question. I have a Verizon Galaxy Note 3. I was wondering if it was possible to flash a custom ROM on my phone If I don't care about tripping Knox after being ignorant and updating to the Official KitKat firmware from Verizon. I've been searching for an answer for this for about a week and I'm not sure if I'm just wording it wrong. The only thing I got close to an answer to this question was someone said that you couldn't do it without tripping knox. I'm guessing that isn't correct being how motivated these phone companies seem to keep their crap installed on my phone. I really don't care about tripping knox and my warranty. I just want to get rid of flipboard and samsung push service off my phone. Can someone please point me in the right direction.
Your problem is you took the official OTA and no one has made a root method that works for it. Plus your bootloader incremented with the update. Which means if you try to flash a lower level one you'll soft brick at a minimum.
Before you took the update you could have rooted and flashed away. Tripping Knox counter only matters if you care to warranty your phone through Verizon or Samsung. If they see the counter at 1x0 or higher they know you've flashed illegal software at least once. They'll deny service. If you don't care. And don't ever intend to warranty or sell the phone. Then you're fine.
However. Like I said. Once you took the update. Unless you were able to keep root using super user survival mode or whatever. You're pretty screwed til someone finds a new exploit.

Thank you for for the reply. That pretty much confirmed what I was suspecting about flashing a different ROM after foolishly updating to KitKat. I had my phone rooted before, but I unrooted it when I was done cleaning up the bloat. You are right about soft bricking the phone. When I tried reverting back to jellybean, it would soft brick my phone and I would have to have to install a back up of the PIT file using ODIN. I'm going to do some more research to see how the authentication process works for these ROM files. There has to be away to modify the contents of the ROM unless there is a predetermined data size and the phone stops the write process. Again thank you for your time and good luck.
Search again, by the way, you can do it now... Just wanted to let you know in case you stopped reading here

[Q] NAE Question

I just had to replace my S4 because I broke the screen on my old one. Unfortunately, the new one was shipped to me with NAE firmware and boot loader already installed. This means I'm already on KNOX from the first second of turning it on.
I have seen plenty of guides on how to update to NAE, and get root, etc. by not allowing KNOX to installed. However, I haven't really seen anything about what can be done if it's already installed. There's things scattered all over the net that suggest there might be ways around this, but nothing on the forums here that I have been able to find yet.
I'm not looking to flash any crazy roms or anything right now, I really just want root, but it seems like even that might be impossible now. Could I use something like "DrKetan Multitool" to "DeKNOX" my device and then root it? Does this tool even work on the S4, he claims it does but I've not seen it mentioned on the actual S4 forums. Any advice would be greatly appreciated. Note, I am looking for a method that doesn't trip the flash counter; or at least allows a reset afterwards. I'd rather not void the warranty on a brand new device if possible.

Try this...it is a custom ROM but really close to stock

I was already planning on installing UnknownForce Stock Rooted NAE Rom, if it's possible. However, you didn't really answer my question. Is there a method to bypass/kill the KNOX boot loader at this point or not? If not, then I might as well just stop now. I'm not prepared to void the warranty at this point.

No. Once you have Knox, you have it.
