[Samsung Galaxy J3 (2017) Questions & Answers] :
You cannot flash any other firmware that isn't designed specifically for the device. It's because samsung makes signatures different for each phone and the bootloader only accepts one signature.

I then Sir have Pandora's box.

Att variant j7. Flashed the early release of the Oreo update.

Now the phone calls itself j7 prime. Samsung sees it as the international version, att doesn't see it and I still can't root the thing lol
[Samsung Galaxy J3 (2017) Questions & Answers] swift5645:
Mind telling us how we could do it for this device? Because I still use this as my daily driver and I grieve everyday wishing I had never updated
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
Its signed by att. I been dissecting the rom since day 1. I don't know how if changed. I flashed with Odin. Thing is Oreo isn't out on my device yet.
[Samsung Galaxy J3 (2017) Questions & Answers] swift5645:
Well actually for this device I don't think Oreo is ever gonna come out. I don't have the skills to develop a root method fir this device but if I could get a partner to help me root this device once more. Because this device has so much potential!
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
The whole method of gaining root thru the binary boot doesn't work? If you need any files I had this phone for a while and have almost everything on it. Stock, combo, notes, videos.
[Samsung Galaxy J3 (2017) Questions & Answers] swift5645:
If you have all the files couldn't you just release a root? Obviously not that simple but still

He has never discovered any root method that he could call his own ...if you updated the old root method ( not discovered by Bobby )might be patched depending on your firmware version..all the files he has is attached to this thread or floating around ..he has said many things in the past without actually being able to demonstrate ANy of his claims or it always turned out he got confused with another device or his computer broke etc etc etc ..he is probably further from root than you are... .better ask [MENTION=4899305]ashyx[/MENTION] for advice and what the correct firmware version is that can be exploited by the root method already released in this thread ...:p
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
Actually, the method found you root this device, I was the one suggested it, I did gain root on the j3, then I stopped using xda because people tend to shove those under the rug. For back thru and read the thread. My devices may have had issues, but look where I went with it and look where the root method went, similar, almost identical to what I said.

They asked about frp, not root.

Anyway to get ES File Explorer to write to the SD card, I can only write to the internal?
[Samsung Galaxy J3 (2017) Questions & Answers] :
yep true and all it took was me to look at the sampwned method and then have ashyx convert the format of the files to be compatible with a different architecture from what the s8 had. sampwned32 came from the fact that the device was ARM which is a 32-bit architecture while the s8 is ARM64 which is 64-bit.

5 j3s I went thru testing different methods. I never claimed to have discovered root. I offered the files I had because they asked about frp. No where was I claiming this my method, I have said I helped in testing and suggested (although at the time was told by certain people it was impossible that way) ways which were used. I in the end had a z3x flash a different version that root was explored on. Then I upgraded and onto bigger better phone, J7
[Samsung Galaxy J3 (2017) Questions & Answers] swift5645:
So why can't we just upgrade the already existing root method especially since this device no longer has random reboots. I'm only 16 and I'm kinda forced to use this phone??
[Samsung Galaxy J3 (2017) Questions & Answers] bobbyp1086:
Not sure, if you can try Odin to the version that can be rooted, I'm on another device

Samsung themselves don't prevent anyone from actually rooting or modifying their devices. They just make it difficult, which is how it should be otherwise every Tom **** Harry would be attempting to hack our devices.

Found a media player that has media control via volume and power buttons that works great and does not require root to use.

Anyway to extract that part of the code and add it to your prefered media player?

The app is called Lisna Music Folder Tree Player.

- when screen is off, you can single click the volume keys to goto the next or previous tracks, and double click the power button to pause or play.

I want to cut that part and add it to EZ Folder Player Free. Is that possible?

Thx, d.

Hello, and thank you.

requesting file

hello guys, i'm new here. can someone here had a backup of EFS file flashable via odin. i am having an error in stock recovery failed to mount / efs and can't boot to android. thanks in advance
[Samsung Galaxy J3 (2017) Questions & Answers] ashyx:
That's probably not your issue, it often states that in recovery.

First port of call for trouble booting is a factory reset and full install of firmware via odin.
[Samsung Galaxy J3 (2017) Questions & Answers] knightlhegnx:
THANK YOU for your reply. i already done factory reset, wipe cache and do a full install of firmware from sammobile but same problem. i think the problem was occur when i flashed EFS file and failed, after that "e failed to mount efs" happen. always booting in stock recovery after switch on and no more charging light and icon. so i think if i flash the right efs file it will fixed the issue of boot up and recovery error i guess, correct me if i'm wrong or if you have other idea tell me. If you have that file, can you give me so that i can test it? thank you in advance.

To those that have updated firmware, can you check your Samsung Experience version or Android ver?

Does it update your version from Android 7 to 7.1.1 so you can get version 8.5 of Samsung Experience?

Hi,

I have a J327T1 from U.S. It supports LTE band B2, B4, B5 and B12. I'm not in U.S. right now. Is there a way to add/lock more bands for this phone? Its SIM/carrier lock is already unlocked. From other threads, people are using QPST/QXDM to add more bands to their phones... I just wonder if there is a similar way to unlock/add more bands to MetroPCS J327T1. If possible, I would like to add B1, B3, B7, B8...

Thanks you!

[Samsung Galaxy J3 (2017) Questions & Answers] ashyx:
The main consideration for this device is definitive confirmation of a locked bootloader or not.

If it's locked everything is a waste of time.

If it isn't then I'll post a reliable root method and compile TWRP, but so I don't waste my time I would need someone willing to flash a test file first.

[Samsung Galaxy J3 (2017) Questions & Answers] :
theres no thread it belongs to. it was created by ashlyx she just uploaded files that she is developing. she has made multiple files for many variants of the j3 (2016) and theres only stock boot and repacked boot for this device listed on her android file host page. those are test files that she is talking about. it is just to determine whether or not the bootloader is locked or not.
[Samsung Galaxy J3 (2017) Questions & Answers] :
I have tested the AZ_Autoroot file i mentioned a few days ago. it fails to flash and download mode hangs with a secure check fail (cache) message i had to extract the original files from the stock rom image and once i reflashed both recovery and cache img the phone rebooted into recovery and said installing system update and it said failed but it booted up to recovery anyways with errors like couldnt mount or whatever. but i rebooted the phone normally and the phone has booted up successfully with no issues. I am guessing we need to find a way past the secure check crap. which most likely means that we need an eng boot or some kinda bootloader unlock.
[Samsung Galaxy J3 (2017) Questions & Answers] ashyx:
Unfortunately 'secure check fail' means a locked bootloader.

However it's strange that the previous poster who flashed the cf_autoroot file said it passed with no errors.

[Samsung Galaxy J3 (2017) Questions & Answers] :
that website is just clickbait. it does not show how to root the device at all. sure it says twrp but currently you cannot get twrp without flashing and we cannot flash anything until we unlock the bootloader. Also i must state that using rooting apps like kingroot and kingoroot are likely to have viruses built into the app. only use those root methods when no other root method works. the lg k7 was the only phone i ever had that i had to root with kingroot.
[Samsung Galaxy J3 (2017) Questions & Answers] ashyx:
It often amuses me how people scour the Internet looking for root solutions and then post the links on XDA asking if they were genuine or OK to use.

[Samsung Galaxy J3 (2017) Questions & Answers] :
i havent came across that issue specifically but i have found a glitch in developer options where i can change mtp to ptp. its probably a bug on samsungs part and they may or may not release an update for this device since they dont update budget phones as much as they should.
[Samsung Galaxy J3 (2017) Questions & Answers] androodius:
The FRP is set by signing in to Google and setting a screen lock and is undone by removing said. It unlocks if you sign out of the account before a factory reset. Just flashing won't activate the lock, but yes if you are unlocking the bootloader it will factory reset, therefore it is wise to sign out of all accounts before attempting an unlock or before a factory reset.
[Samsung Galaxy J3 (2017) Questions & Answers] :
yup that is correct.
[Samsung Galaxy J3 (2017) Questions & Answers] :
AZ_Autoroot Fix

If you get a secure boot error i have made an odin flashable tar file that you can use without having to use the entire stock rom image files to fix it. all you need to do is extract the zip file and select ap in odin and select the tar file then flash. the phone will reboot to recovery automatically and show an error but ignore it and wait for it to boot into recovery. once it is done booting to it just reboot to system. if you boot back into recovery afterwards there will no longer be any errors.

it looks like our device cannot be bootloader unlocked. our device is one of the unlucky few which will not let you unlock the bootloader.
