[A500FU] Binary=CUSTOM Knox=0x0 - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

Bought a A5 (SM-A500FU) on ebay and noticed that binary and system status are custom wich usually means the phone has been rooted/custom firmware has been flashed but knox status is 0 wich implies that only signed firmware has been flashed.
Does anybody have an idea why idea how that couldve happened?

There is nothing to worry about. Knox 0x0 means no root, since forever.
For peace of mind, run Phone INFO 3.8.5 and check.

[Q] i9500 warranty back?!?

Hi all! I don't know if I am missing something/this is normal/this is new. I rooted my S4 android 4.2. Realised that triangle away doesn't work for i9500 So lost my warranty. Ah well... Yesterday I decided i would upgrade my firmware (as my provider just released one). Kies didn't work and just kept stuck at 0% so i copied the firmware file from temp folder and used odin.
Now I have 4.3 on my phone, tried to do something in root folders but it wouldn't let me as i don't have root anymore.... I checked my download mode and it looks like this:
cant post images yet
product name: GT-i9500
Current binary: Samsung official
System status: Official
Warranty bit: 0
If its been rooted (FOR i9500) and warranty is void it would say :Warranty bit 1 (right?), with a counter next to the current binary?
bottom line... my warranty is back for some reason? Or am i missing something...

[Q] Does Knox really lock radio updates?

Hi
I'm not overly fussed if Knox is tripped or not. What I do want to know though, is if its true that radio updates can't be applied once its tripped?
Cheers
Why would you think this? I can't think of an obvious rationale for Samsung doing that.
In the narrow sense of whether 0x1 would prevent an automatic OTA update.. I don't know. I've never had reason to suspect or look into that. I can tell you that you can manually update the radio with a 0x1 flag.
.
That's what i figured.
I was reading one of the rooting threads and someone was saying that once he had 0x1 he always get a secure error when trying to flash the radio.
If it's fine then I'll just CF Autoroot rather than fussing with towelroot
What is radio ?

I think he must be confused about the changes that occurred with the 4.3+ OS. The bootloader after 4.3 is more restrictive and will sometimes balk at flashing a radio, but it does so for both 0x0 and 0x1 flags, so it's a moot point. The workaround to that is, if necessary, is to flash a full firmware image which will succeed in updating the radio even with a 0x1 flag.
He probably incremented his Knox flag right around the time 4.3 came out and doesn't realize what is really going on. That behaviour i.e. bootloader authorization failures appears to vary by carrier and radio version FWIW. But again, in the worst case, you can still update your radio by flashing a full firmware image.
You could preserve your Knox flag by using Towel root. But you wouldn't be able to use a custom recovery or kernel without incrementing the flag and I for one would not give up either.
The only things that the flag really effect are the secure storage feature that few use and the supposed effect on your warranty. But it's usually Samsung direct trying to deny a warranty claim due to a 0x1 flag. Most carriers don't care about Knox, so claims made through carriers are typically unaffected. And Samsung can't enforce that prejudice in the EU either.
@pratto
The radio (aka modem) is the firmware component that enables your phone to communicate with the carrier's network.

Cheers for the info. I'm in the UK so root I will
I'm only after root for the Folder Mount app.
I preferred this method of effectively swapping the external and internal SD cards myself. But either way, I'm sure that you will find root useful.

s4 and knox upgrading

I need some help. It has been awhile since I messed with my husbands s4. He has the origonal from like 2 weeks after release. I did upgrade his phone once. I THOUGHT he was knox free but I honestly do not know. I see no sign of knox when the phone boots into twrp recovery. But I thought in order to be knox free he had to be on like mf9 bootloader or something but it looks like his system is straight nae. his status says custom (which I chalk up to having twrp). but knox shows in the app list and it says se android enforcing and secure boot status says samsung. security software says mdf v1 release 2. baseband and build say nae.
he cannot install any apps from the amazon app store and I thought it was the sd write problem but I have tried all the fixes and no luck. He would like to upgrade to the newest but if he is not knox installed than he would like to stay that way. I dunno if on the s4 you can have twrp and still not have tripped knox???
any help would be greatly appreciated.
please help

also when going into download mode it looks like it says 0x00 which would mean know not tripped.. but I have twrp installed.... is it possible to have knox but not tripped even if you have twrp installed?

[Q] Reading the custom binary counter

Hello all, I've got a AT&T S4 sgh-i337 with the locked mk2 bootloader. Bought new, still under warranty (well.. supposedly
I'm trying to go back to bone stock to return it; I think I did because when going into odin download mode, I see the following:
PRODUCT NAME: SGH-I337
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
KNOX KERNEL LOCK: 0x0
KNOX WARRANTY VOID: 0x0
CSB-CONFIG-LSB: 0x30
WRITE PROTECTION: Enable
eMMC BURST MODE enabled
I did lots of reading and found some info I don't completely understand (go figure haha). I read that even when the S4 does not DISPLAY the binary counter, said counter is still there and reviewed when the phones are returned.
My 2 questions are...
1) if the custom binary counter is indeed there, is there an adb shell command I can run to READ the counter?
2) if the binary counter is there and I need to reset it... will the triangle away method work with my locked (and "unlockable" mk2 bootloader? -- under supported devices for triangle away, I see "Samsung Galaxy S4 AT&T SGH-I337 UNLOCK BOOTLOADER".. I'm afraid they meant to say "UNLOCKED" bootloader... in which case, I'd be out of luck.
Thanks a bunch!
R
No one knows? any info or guidance? Thanks
The following is just my opinion.
Both Samsung and AT&T offer a 1 year warranty on the Galaxy S IV phones. Since you are on MK2, I would guess your phone is at least 1-1/2 years old, so any worry about the warranty is pointless, since the phone is no longer under warranty.
You want to return the phone to AT&T? If that is the case (you don't state where) then the likelihood of anyone checking any of the counters is extremely unlikely, let alone any hidden counter, if it exists.
In my opinion, I wouldn't worry about it. Just flash it back to full stock, whichever version you can put your hands on, and you'll be fine.

Thank you very much for taking the time to reply creepyncrawly! Much appreciated.
I was going to return it to Samsung as I bought it refurbished at BB a couple months back.. I believe they honor the 1hr warranty on factory refurb phones (but I might be wrong)
Anywho.. I kept working on it, testing new stuff, different stuff and finally was able to get everything working nicely by forcing it to take the I337UCUFNB1 upgrade.
Thank you again, cheers!

N910F IMEI recovery

Hey, I just bought used Note4 N910F model for very cheap price - 230 euros. Phone used just about 5 month from buying, I have warranty paper to prove and IMEI on warranty paper is the same as on behind phone battery but... Seller told me, that warranty was voided because, he got some virus that blocked his phone, then he went to not authorized service and flashed ROM but IMEI changed.... and know KNOX settings not opening, on phone info from google play says Knox warranty void: 0x1. when trying OTA update I get error that phone was modified unauthorizaded way and cannot update. So is there any way to flash stock with original IMEI and I can get KNOX settings working and OTA updates :/ and noticed that TWRP recovery was installed... maybe some wipe could restore IMEI? and when booting I can see "set warranty bit: kernel" yellow sentence on top of screen
Knox will not work anymore, you can install stock firmware trough odin. Go to sammobile and flash latest stock
