What do you mean with updates it boots okay, put keeps updating the apps each boot, or it hangs on a logo.
If you root you can't download updates anymore with the ota feature.
You could try this, in the first page there is an uninstaller for magisk in the dowload section.
In worse case you have to flash a new rom again.
ps. you should post in the Q&A section.
This is for asking questions of a rom, or like you did now the present a new rom

how to update OTA rooted + twrp sprint.

I have galaxy s4 with stock room from sprint. I had rooted it and installed twrp custom recovery. I was trying to update the phone with OTA update but it rebooted to twrp and that is it. I tried looking for update/zip to install but nothing, update check says it was updated.
Did the update still install somehow?
If not, Where is it downloaded to update or recommend an update method?
I am also concerned about losing root. How can I avoid that in the future?

Does a Rooted Note 3 get OTA Updates?

Sorry if this is a newbie question, but if I root my Galaxy Note 3 (N9005, Vodafone Australia), will it still get OTA updates?
I ask because I used to have a HTC Desire HD, and after rooting and installing Cyanogenmod, I tried to put the Nandroid backup of the stock rom back on, which was fine but for some reason wouldn't install the OTA updates. It would tell me there was an update and download it, but would fail to install.
Thanks!

If it does install you will loose root... But I believe if the system is found to be custom in any way it will fail on install of OTA or will actually tell you that the phone has been modified and no updates available for you

Thanks for the reply. Just out of curiosity about the HTC Desire HD that has since been given to a less tech-savvy relative, is there a way to unroot so the OTA update will work??
I rooted my N3 3 days after buying and then tried to get an OTA update. It didn't download first, as my phone was set to custom. After using Wanam's setting to "reset" the custom status, I could download the OTA update but couldn't install it.
Basically, with root you can still check if there's an official update available, but you can't install.

Anyone know how it actually tells if the phone has been rooted? Surely there's a way to reset it to unrooted/non-custom state so OTA updates work again...

The boot loader and the os itself scan for certain things such as modified kernel/recovery or installation of busy box.
The Samsung's aren't so bad, you can just flash back the stock rom and factory reset to start getting ota updates again. On htc phones you have to unlock the boot loader to root and its a one way process. Once unlocked you can never get ota updates again.

i have the same problem here, i would like to update MK2 but i cant.
used wanam exposed for fake > failed @ installation.
do i have to unroot or factory reset for update?
i dont want to install a cwm at the moment.
thx
Once you have rooted, the system partition has been modified so Samsung doesnot allow you to OTA update. It checks MD5hash for the consistency. Factory reset doesn't help because it only format userdata partition.
If you r rooted, better go to sammobile.com, download the latest firmware version, copy it to sdcard and flash via Mobile Odin Pro. This way you can keep the old bootloader so you can fallback (downgrade) to the older firmware later.
Thank you.
what is when i tripped the knox count?
Its 0x1 now. I was on new bootloader before.

I need to keep Knox at 0x0.
There must be a way of updating.
A couple of people have mentioned downloading from SamMobile and flashing back to stock. If I do this, what happens to twrp?
If twrp stays, I don't want it conflicting with a non-rooted phone (due to flashing stock) and being bricked
U can get upgrade with kiss not OTA but u must install wanamp exposed n change system into official. Its work on rooted stock rom.

After rooting a Samsung device, the firmware changes the status from official to modified or custom.
Go to recovery, wipe cache and dalvik then do an OTA. if the problem was still there then factory reset or flash a new firmware.
but you still need root! This process is very long, it cannot be done with every OTA.
You better flash or update your firmware using Odin.

Using Triangle Away, remove the CUSTOM status first
Then Remove Root and UNROOT your device
Then do OTA update
Then Root by Chainfire Method (its very simple)
Tada, you're done
Hope it helped :good:
There are problem from the triangle away..they did not work

Bro,
Had some doubts before i flash:
1) You mentioned do clean wipe and flash that ROM. Do i need to install stock recovery and stock kernel before that? I have custom recovery (CWM) installed right now.
2) After installing your this ROM will my phone be official, unrooted? Will i be able to get the official OTA updates in the future?
Please let me know.

Done and running official 5.0.2 now. Hope will be getting future official updates from now on. Thanks a ton bro. :good::good::good:
I flashed the the 122 mb update and got the error, but it was fine when I flashed the OTA LP again and flashed the incremental right after it.
But unfortunately (or fortunately ) my Mac address was lost had to flash a custom kernel to make it work. Was it the same for you?
And I don't see much difference with the phone, the battery lasts around 8-9 hours on games (heating is still on).
I do like to know if there's any difference for you guys

[SOLVED] Please help - Stuck on Samsung Logo after root.

Hi all,
Im using an S7 Edge on Nougat.
I used odin and cf room (https://download.chainfire.eu/930/CF-Root/CF-Auto-Root/CF-Auto-Root-hero2lte-hero2ltexx-smg935f.zip) to root my device.
After the process finished, my phone rebooted but stays on the animated samsung logo.
I've done a search, and im a little lost - please help - any help is useful.
Thank you
I never used Auto Root but if you look at the chainfire page, and see the S7 Edge it is just for 6.01 and not nougat. I think that's the problem

I think that you need to flash the stock firmware for your country with ODIN. Maybe someone else can verify this?
Trying this and im getting Secure check failed (bootloader).
I'm scared and need help.. Anything?
Hi,
You have to flash a Nougat stock firmware if you wish to flash using Odin. Samsung bootloader (Knox) doesn't allow an official firmware downgrade, and IIRC that message you are getting happens when you're trying to flash an older version of Android.
Get a newer stock firmware and try again, or if you prefer you can just flash a custom recovery and flash a custom ROM (which may be faster and already comes rooted). Also next time search for a rooting method for your Android version, rooting uses of the system partition, that means if you try using an old method, there's a risk of something not working fine.
All the best,
~Lord

Hi Lord,
Just did what you mentioned, you were spot on - the older bootloader caused issues with the data partition so i lost all apps/data and had to start from a scratch nougat install.
All is working now - appreciate your help, both of you - i will research more in future.
