Hi, I have a Samsung Galaxy S6 originally on EE and I had it unlocked to 3. I am unable to do an update as via WiFi and I am presented with the following message, "The operating system on your device has been modified in an unauthorised way. Try downloading software updates using Smart Switch on your PC or visit a customer service centre".
I have been told that the unlocking of the phone has resulted in me not being able to use smart switch and that the phone is no longer connected to the Samsung servers.
The build number is LRX22G.G920FXXU1AOCY
I am using Android 5.0.2. at the moment.
If you're rooted you get that message.
Best thing to do is download your current rom again, flash it with odin and that'll restore everything to stock and allow the over the air update to be downloaded. (It doesn't wipe your phone)
Alternately download the latest rom for your model and flash that in odin and it'll update it.
Not that there is no (easy) way to root 5.1.1 without tripping knox.
How do I know if my phone is rooted or not?
Are there any obvious signs that will indicate whether or not the phone is rooted?
If the phone is rooted, where can I find the correct rom for my device and what are the steps to carry out this process?
Hello,
I've been on XDA for a while and I'm more than familiar with rooting/ROMing/unlocking/etc (so don't feel like you need to dumb things down for me), but now I've got something I can't figure out.
So my sister-in-law has a C-Spire (yikes, I know) Galaxy S6, Model SM-G920R7. It's a very unusual model, the only place I've been able to even find firmware for it is from the SamFirm tool. There's no support/testing for it anywhere really, so I've just been experimenting with it using the usual methods to try and root, but nothing seems to be working as intended.
It seems to be most closely related to the Sprint variant, so most methods I've tried were based on the methods for that model (SM-G920P)
All methods end with the same result: SuperSU is installed but there is no Binary. (open the app, it says no binary installed)
What I've done, in this order:
Install TWRP then SuperSU latest: No superSU binary
CFAutoRoot for SM-G920P: No SuperSU binary
Install custom unversal kernels (tried hacker kernel, UniKernel, and Arter97) then SuperSU: OS won't boot
Tried to restore system from TWRP backup after all these failures: success but OS won't boot (DM-Verity issue for mounting system RW?)
Finally I just used ODIN to return it to stock so it would boot (latest firmware G900R7WWU3CPF2)
So now it's right back where I started, stock everything with no root and now the addition of a tripped knox. Any ideas on how to get this thing rooted?
I assume because I was able to install TWRP that the bootloader is unlocked. Is that a correct assumption?
If it boots fine, I'd say BL is unlocked.
Look here, especially the section called "Android Version" https://autoroot.chainfire.eu

Check in Developer Options to see if there's an OEM unlock toggle.

Could really use a hand with this, has anybody successfully rooted the c-spire variant?
Did you submit the BL to Chainfire?

use the cf auto root download this use google to search first one that comes up use that link go to model sm-g920p cspire and sprint uses
the same network . Use odin to install i have same phone and have mine rooted in this way. So far tried using the sprint version custom rom it will work but you can make phone calls but not the data side for phone internet.

It says cf auto root has been changed or something!? Plz Help
So yesterday I got this Samsung Galaxy S III that was I535 but had a I9300 4.1.2 Firmware in it. (I don't know how was it there) It had been rooted. I don't know about the bootloader if it was locked or unlocked.
I wanted to install the official firmware for i535 so I used Odin to flash I535's official 4.4.2 (downloaded from sammobile.com) and it worked fine. I then used towelroot v3 apk to root the phone and it got rooted again, then I used safestrap 3.71 to install custom recovery and that too went well.
I then flashed a zip to get Motolora Cricles widget, although that didn't install properly but my phone was still working fine until then. Then I used EZUnlock14 to unlock my bootloader and the app supposedly decraled that my bootloader was "now" unlocked, again I couldn't confirm because that's when the problem starts.
After closing that app I plugged in my phone through usb cable to my laptop and had been using it for facebook and texting. Then I turned off my phone and it never turned on back again.
When I connect it to the PC now, it is not recognized and Device manager shows QHSUSB_DLOAD device
I hope somebody can help me with that.
well, ya dun messed it up. But its fixable. For future reference, never try a bootloader unlock app, thats what messed yours up. Those apps only work on 4.2.2 bootloader phones and have caused many a headache for lots of folks. Lemme grabe you a link quick.
here ya go. this will get it fixed for ya

Hey I'm new here and hope I've got the right area to post in if not can you please direct me to where I can request an update to the CF auto-root for SM-G920W8, it is at 6.1 but I have 7.0
Hey I have an SM-G920W8 and I'm attempting to root for the first time just for pogo to get around the new update.
I've downloaded odin and the guide I was using last night warned not to flash a rom with a different version than your phone or it could result in bricking your phone.
I've figured everything else out, my phone is recognized and I can boot to download but I'm afraid to flash the old version.
I have no idea how to create any of this on my own so I'd like to formally request an update for this version of the phone.
Thank you for your time and directions.

Chainfire I am also wondering if there is plans for any CF-Auto root for our Canadian phone now that the Version 7 ROM is out?
Is there anything needed from us to get this update of CF-Auto root added to your list?
if no CF-Auto root can we flash the SuperSU 2.82 using TWRP for our phones? I tried 2.79... and TWRP stopped part way through and got a bootloop when i rebooted the phone.
Hi everyone, I bought this samsung s7 sm-g930w8 phone and I tried to root the phone but was unsuccessful.
Now I can't enable OEM unlock. It's not grey out but it just unenable.
For some apps it said can't be opened on a rooted device. When I checked with rootchecker it said root access not properly installed.
I already tried to unroot and do a firmware reset but nothing change. Please help. Thanks

So that is a Canadian Exynos device yes?
First thing to try is to make sure your following any guides exactly and are using the correct version of any files. Then try rooting it again. I'm going to assume your using Odin in download mode and it doesn't give you any errors but a "pass" when complete.
Also I've always found it much much easier to install TWRP first then root.
If none of that works,download firmware,flash with Odin and use Home_csc so you don't lose your data.
It would be helpful if you provided your firmware version, cell carrier, locked to carrier? Etc
