Ok so I rooted my galaxy note3(about a month ago), but today when I turned it on the phone instantly installs a new update without my permission and takes away my root. This would be fine, but now my phone says "custom" when booting up and it is not rooted anymore. How would I be able to take away the "custom" boot image? I am seriously considering selling att GN3 at this point(tired with ATT bs and lack of any info on updates) and opting for a nexus 5. My only problem is that people will be turned off by my previous evidence of rooting my device because it says "custom". I essentially would like to return my phone to all stock settings.

Try simply rebooting. That worked for me after unrooting via odin one click on mi9. The first boot showed custom wich confused me but after just a reboot it went away. I think it softbooted after odin and didnt run through the whole process.
If not then the only option currently to remove custom is to re root using kingo then use xposed to fake custom system status. The latter would be shady however if you plan to sell the device.

Sorry to bother you, but I am not too familiar with how to do this. Would you be able to show me some sort of step-by-step guide which I would be able to use? Also how do I check if I'm on mi9 and not something else(because I currently have the most updated firmware on my phone)

The most updated is mj5 if you took the ota update that hit recently. You can check by going to settings then about phone then look at the last 3 digits of the baseband.
To install xposed go to the link at the top it pasted there on my tablet for some reason. Instructions are there for installation.
download the xposed installer apk. You must be rooted. Use kingoapp for that if necessary. Open xposed installer and go to framework. Install the most recent framework. Then go to download. Download cosmetic device status normal modification. Use that to remove the custom padlock. Reboot. Hit thanx

So, I am on mj5 right now since I got the OTA update and I am no longer rooted because of this. How can I flash to stock or reroot and install xposed? Or am I ****ed?
*EDIT USED KINGO INSTALLED FRAMEWORK ALL IS GOOD IN THE HOOD *
Today i bring you the very first rom for our device.
It's only stock, but the installer includes enough options to keep us happy for a while.
The core installation includes a stripped down system menu with Google play and contacts. I also added, by default, the WiFi fix and hotspot mod. The rest of what you install is your choice.
Aroma options:
Choose which J320 you own
Debloat (fully customizable)
Deknox
Install root
Install busybox
Install Init.d
Install Xposed
Bugs:
None
If you find any let me know, but if you do not wipe, please don't even report bugs.
Link:
Download
Installation:
Flashfire
Enjoy
-D
This uses the same base files for each room, AQG1. So even tho the highest firmware for J320AG is only AQB1 you still get the July security update (minus the new sboot)
All devices are interchangable for me, on Cricket. Depending on your carrier maybe they'll all work for you too.
I have AT&T Samsung Galaxy Express Prime GoPhone, J320A. Owned it for one week. It has been carrier-unlocked. I'm now using T-Mobile SIM. Seems to work OK. Only issue I can find is where the SIM status page does not show my phone number.
I would appreciate pointers or maybe a place to look for installation steps. I assume I'll to need to root via Kingroot then replace with SuperSU (if possible). Then install FlashFire. I have rooted and installed ROMs on other devices (Galaxy Exhibit, 2012 Nexus tablet, Moto G), but seemingly devices are more locked-down these days. I understand that TWRP is not available for this device and likely will not be.
Last year, I bought a couple of inexpensive T-Mobile phones and "rooted" them with KingRoot which is still installed on those phones. (Not really thrilled about that.) I put rooted in quotes because it doesn't quite behave like a fully-rooted phone, IMO. I'm not very expert in these things, but I know how to follow steps and have used ODIN, TWRP, et cetera.
I'm leery of working with these more locked-down phones. Am I being paranoid and/or incorrect about these matters?
BTW, thanks for the ROM! I'm surprised there aren't more replies.
Maybe this phone is not as popular as I think it should be. Maybe it's too low-spec for the tech-savvy crowd. I got mine for just $64 at Walmart online, but they've since raised the price to $79. Seems like a good deal, even at that price.
I paid $15 to carrier-unlock it. I had to flash firmware (modem file?) before unlocking, then flash another file (restored modem?) after unlocking. I was following emailed instructions after the initial unlock procedure failed.
Here's the root thread
https://forum.xda-developers.com/galaxy-j3-2016/how-to/root-samsung-sm-j320a-galaxy-express-t3573628
There's a xposed module that does just that, never tried it tho, and of course it's not permanent.
https://forum.xda-developers.com/ga...pp-sim-changer-change-registered-sim-t2106490
I definitely like the phone and yeah, it's a good price.
Being locked does hurt it tho. No easy recovery and no roms from source. The only thing we might get will be ported. And with no kernel, porting is a pain to track down problems... but i like a challenge
My J3 was unlocked out of the box? Still don't quite get the different names for it though. Rooted with infixremix method and worked fi e until its download caused the dialer to crash whenever it was opened. Still trying to sort out the mess I made of this one.
original stock
hey do any of you guys know where I can get the original firmware to restore this device? mine is the S/W: j320aueu1ape9
on the box it says j320x UD
Odin files are posted here

How is this ROM working out?
Can anyone -- or DamienMc, the creator -- post a review of how this ROM is working out? Brief or long; any type of review would be appreciated.
I'm thinking of trying this ROM and I haven't rooted my phone yet.
Although I did unlock the carrier via a paid unlocker site. I'm using it on T-Mobile with no apparent issues. My phone is stock, of course, except for being carrier-unlocked. …Several questions, if I might:
Are those "extra" AT&T and Samsung accounts present? (ref. screenshot)
Are Samsung factory (i.e.: theme-able) dialer, messaging, and contacts apps installed?
Is it still possible to theme the UI with the Samsung theme installer?
Finally, which bloat icons have been purged? (ref. screenshot) I realize one's idea of bloat may vary from individual.
Any feedback or commentary is welcome. Thank you for your consideration.
could it work on J320H?
i know it's for 320A/Az but i want to try it

I'm not going to review it (someone else can)
But I used it heavily before I started work on something new.
It's as stable as stock... cause it is stock Nothing tweaked just the few add-ons to let you tweak it easier.
About the bloat.
I did notice I should have left Samsung account (and maybe billing) with the standard install. Because you can't use the theme store without them. But they're in 'bloat'.
You can always install all the debloat options and have 100% deodex stock and edit to your liking.

Sorry bud, different chipset
How do we flash this to our device mainly because twrp and cwm ain't a thing for the j320a. Also I'm using kingroot and I cannot go to su I've tried also flashify does not work either does flashfire how would you go about rooting with su cause I've tried the mrw method and contanstaly it would pop up kinguser has stopped working so do you have another method of rooting the J320A. I just followed the first post about rooting it.

I just rooted my phone with Kingroot and used the mrw method to remove it well keeping my root. after got Su in my terminal emulator, I deleted the kingroot apk not the app itself. then just installed SuperSu thru my play store and been working just fine for me.

After mrc and kinguser crashes you should have supersu. You need to run that first, let it update the files and then reboot.
If su doesn't even get installed, have the apk ready and install.
Another thing you should make sure your really rooted, reboot after king and recheck.
Also what versions of kingroot and mrw are you using?

I followed the rooting thread OP directions carefully and had many problems. My initial Kingroot was really ugly and heated the phone. I then attempted to use SuperSU-Me Pro (paid version). It was never able to complete, even after several tries. I struggled using various techniques over many hours. (I did have root with Kingroot.) Nothing would remove Kingroot 5.0.5, and as you probably know, Kingroot won't allow for many apps such as Flashfire. Very frustrating. I probably shortened the life of my phone and battery with all the crap I tried. Many pulls of my battery were needed.
I finally wrested control from Kingroot by uninstalling version 5.0.5 and installing Kingroot 4.5 instead. Then SuperSU-Me Pro did its work. Had I used Kingroot 4.5 from the outset, would things would have gone better? I don't know. The rooting process for this phone is a one-way trip with a dubious outcome. I know the Express Prime is not costly, but if you're risk adverse think twice before trying to root. I suppose you can undo the whole thing, but I haven't tried and likely will not.
Despite the problems I had, I believe using SuperSU-Me Pro was worth the cost and ultimately saved time. I'm glad I rooted my phone, but -- damn, it was a lot of effort compared to previous phones and my tablet.
I have not tried the de-odexed ROM posted in this thread's OP, but it's on my to-do list. I'm kind of afraid of messing with my phone for the time being. I'll post a review if and when I try it out.
For what it's worth, I wasn't able to get my built-in flashlight toggle to work. I ran the fix script via flashfire with no success. Update: Fixed after installing Busybox. Thanks, DamienMc!

Greetings from germany,
a buddy of mine got a Note 8 from a shady seller and it turned out that it had a custom rom:
Basisbandversion: N950FXXU1AQHB
Kernel-Version: 4.4.13-theGreatDream-v1.0.0
[email protected] #1
But he couldn't do any updates with it and quite a few apps didn't work because they said: "device is rooted and because of security policy etc..." (crudely translated from german)
such as the samsung and banking apps.
So we tried to go with the guide on how to flash and restore the device to stock firmware with odin.
For that i downloaded the N950FXXU1AQH9 version which is for the region germany and that seemed to be the most reasonable choice in the vast variety of approx. 200 available versions.
We did everything exactly as described in the guide and everything seemed to work perfectly. Updates were working again and also the banking app worked.
But the day after he wanted to try the Samsung Health app and it reported to not work because "security policy, can't open on a rooted device" (crudely translated from german again)
and others like the banking app also stopped working and reported the same.
Although we installed the N950FXXU1AQH9 version it now says in the softwareinformation that N950FXXU2BQKG is installed Oo
Strangely he also tried some apps to root/unroot like superSU etc. and they all told him "your device isn't rooted"
So regular apps tell "can't work because device is rooted" and root apps tell "can't unroot because device isn't rooted"
So i ask humbly: where is the error in this mess? What shall we do to make this device into a perfectly funtioning unrooted freshly fabricated note 8 again?
Thanks in advance

I think that once rooted and Knox has been triggered the banking apps and certainly Samsung Pay will never work! I'm not thinking of rooting my SM-N9500 (I don't think I can anyway as it's Snapdragon), I used to root to get rid of adverts but Samsung have an app for that!
Sent from my SM-N9500 using Tapatalk
Once KNOX hasa been tripped its a can't be restored... You might b able to trick some of the apps into working by using a custom kernel but secure folder and KNOX are gone like the dinosaurs...
You should be able to find out about the custom kernels & how to flash by doing some reading.

I agree with this, I know that once rooted, some apps will not work anymore on that particular device, regardless of what you will plan on doing with that device.
knox is tripped.
the phone has most likely been successfully unrooted, but rooting it permanently makes alterations to a chip on the motherboard.
some apps will never trust this phone again, unless you can hide the knox fuse status.
so to get full use of the phone again you'll have to root it again and look into some root hiding apps/mods.
unfortunately I can't help you any further with that, I haven't rooted a knox-enabled device since the note 2.
Firstly thanks for all the enlightening answers. Now we are getting a bit closer.
I have just started with those topics on modding (rooting) of smartphones a few days ago and none of the guides i read mentioned anything about knox.
But yeah everything is gonna be more complex than anticipated. I will have to start digging deeper into this matter and try out a lot more of modded kernels and root hiding tools etc. to restore funtionality.
I will keep you updated on my progress... or lack of it :]
puzzlednerd said:
On another matter: The guy that "sold" my buddy this Note 8 seemed to be very eager to give it to him. At first he made an offer on local ebay and said that he didn't want his note 8 because it is rooted and modded etc.
My buddy made an agreement with him to exchange his older less worth samsung, which was all original and unrooted, for the sellers note 8. The seller complied although the difference in worth was approx. 250 Euro.
My buddy was happy that he made great deal... at first...
Later we found out that the same seller is selling my buddies old phone on local ebay again and surprise surprise it's rooted and modded again and offered for a much smaller price than what it's worth.
Now... is it possible to root and hack those phones with lets say... keyloggers and give them to unsuspected customers that enter all their account data and banking information?
Otherwise i have no idea why this seller is practically almost giving them away for nothing and is rooting formerly unrooted devices and sells them with the point that he doesn't want rooted devices and losing money with every trade.
Scam detected? What do you think?

Hi all,
I am trying to relock the bootloader on 3T, with no success. I want to do it because of too many apps nagging me or not working with unlocked bootloader
here's what I did to unlock in the past and relock:
unlocking:
- enable dev options, enable oem unlocking & usb debugging
- flashed TWRP & fastboot oem unlock from command line (don't remember which I did first)
- got my phone wiped which was an an unexpected surprise!
- bootloader unlocked, the fist of those lovely warning screens telling me so
- tried to root without success, so no custom ROMs for me
- lived with it like this for a while, too many apps telling me they won't work, decided to relock
- got latest stock ROM, flashed it via TWRP, wiped, tried to fastboot oem lock ==> success reported by CLI, BUT device still unlocked
- flashed just the 3t recovery img, wiped, fastboot oem lock ==> success reported by CLI, BUT device still unlocked
- tried the qualcomm unbrick tool after installing the recommended drivers, can't have it see my device maybe because it's not bricked or maybe some other reason, I don't know. it doesn't show up in the app. Will uninstall and reactivate driver signature checks soon unless someone explains me how to make the bloody phone show up ...
So at this moment I have a many times-wiped phone with latest 9.0.4 stock ROM whose bootloader won't lock back. I am quite at a loss. I haven't tried any magisk or similat, SuperSU at the time told me I am not rooted.
I am tearing out the few hairs I have left. Any help for this poor family man so that he may not be allowed to walk in darkness? (quote from Uninvited). Thanks
Why don't you use Magisk hide to hide root/unlock status to those apps instead of loosing root/adaway and more?

I have never investigated Magisk, I think I installed it at the tima but there was some problem with it so I uninstalled it and didn't think much more about it. The problem is, my phone is not rooted (even though I tried it failed, I unlocked the bootloader to root it in the first place but was not successful), only OEM unblocked. So, so to say, I'm stuck in the worst of the possible worlds except for a bricked device. unlocked with no apparent way to relock it, and not rooted.
I feel like my phone is in some strange state where the normal procedures do not work. If I could at least figure out what's wrong with the rooting, I could go the full way AND then, in case use Magisk. but at the moment I feel like there is a need to put the phone in a known definite state whichever it is and work from there. I'd be happy to revert to stock and locked and then redo everything when needed in the future.
How could I troubleshoot further or get to such a "known state"? many thanks
The thing you did wrong was using the outdated SuperSU method of rooting which is not supported anymore. You should just flash the latest Magisk zip of their github page and then you will have root with the possibility of hiding it for bank apps and others.

Hi, update. I installed Magisk but, seeing that it had a way to put the phone in EDL mode, instead of going full root I decided to go the other way around and try to make my phone as stock as possible and reserve the experiments to an unit other than my primary. So I used the Qualcomm "unbrick" tool, and was able to flash the OxygenOS version that came with it - a rather old Android 6 whose networking (wifi, mobile...) wasn't working. But an adb sideload of the latest version after having put the phone in recovery mode allowed me to restore the networking and to update to the last supported version.
Magisk made the difference in getting me out of the spot. Thanks for bringing it to my attention!
Hi all.
So it's been a while that I've rooted a phone (Note 4 years ago).
Getting a refurbished Note 8 very soon (UK).
I just want to root it and install only what's needed, without applying custom roms etc.
Just need it rooted for Titanium Backup, modded Google Play. Stuff like that.
Hope someone can help me in how I should go about it.
Also should I update the phone to 9.0 as soon as I boot it up?
Thanks.
Edit: Got the phone now. It took me to the home screen when first booted up. Looks like already updated to version 9. Does rooting still trigger KNOX?

Yes rooting will trip Knox.
To flash TWRP just follow the steps in this thread - https://forum.xda-developers.com/t/recovery-official-3-3-1-x-twrp-for-galaxy-note8-exynos.3832962/ (just use the latest TWRP which is 3.5 I believe)
If you're just going to root stock filmware you will need to flash RMM/KG bypass or you will get locked out of your phone (only official filmware can be flashed error, then you will have to flash stock to fix it) - https://forum.xda-developers.com/t/...ll-twrp-on-exynos-samsung-after-2018.3747535/
If you are going to flash a custom rom they have the RMM state prepatched so this step would not be necessary. To flash a custom rom just follow the steps laid out in the OP of the rom you want to use.
