What is this app ???com.samsung.android.isag.issmanager??? - Samsung Galaxy S8 Questions and Answers

The phone appears to be a pre-release version of the S8, sm-g950f. I bought it on OfferUp, and this app started appearing immediately after doing factory reset. Now it pops up about every 30 seconds. I've tried to sign in with my Samsung account, and tried calling Samsung directly, but that was no help. They couldn't even find the IMEI. I ran the IMEI on IMEI.info and it was clean, and root checker doesn't show anything being rooted. Any info would be appreciated.

You can try to download stock Samsung firmware files with Frija and flash it manually with Odin.
Then boot into the newly installed system again.

This device is locked because of an abnormal factory reset note 4 :crying:

Need help with this guys.
Here is what happened. First of all I purchased this phone from a Gumtree user a while back. (stupid I know). Anyways 2 weeks after purchase i noticed my imei number wrong in the phone as opposed to the back sticker. I searched around on the net and some people had the same imei number popping up due to prob rooting or unlocking (my phone is not rooted btw and it is unlocked but i have found out that it was originally locked to EE). I left it for around 6 months before i realised i needed lollipop and i was stuck on Kit Kat as the phone would not update,
So today I noticed someone online showing how to update through Kies using the serial number etc on back of my phone through recovery without Odin or root. I did this and it updated my phone to Lollipop and my imei was back to normal ... The happiness soon died off when i realised my phone would not let me pass the Samsung account stage. Just keeps saying: 'This device is locked because of an abnormal factory reset', and if i fill my details and press enter it gives the following: 'processing failed'.
My phone has updated to the latest 5.01 lollipop but I cant use it. Is there a way i can remove this or login with my details? E.G. by rooting the phone or downgrading to another firmware via odin or something?
I have tried everything. I've spent a whole day on Youtube and the net (I prefer to seek a prob usually before asking) and now finally i am resorting to ask for help from you advanced users.
I hope you can help me. :'(
I have fixed the issue. Well sort of. pending.. For anyone that wants to know..
I reverted to android 4.4. (i used three uk firmware)
downloaded slidesych, that then propmted me to open either a browser or samsung app store.
I clicked app store and then searched for any app to download. It then asked to login..
logged in and pressed back to the point of it asking for details. inputted my login and worked..
Went in to settings and removed the lock.
Now to update it again back to 5.1.1.
Update: Today flashed the stock rom for my phone via Kies by recovery mode and entering serial on the back of my phone. All is well to the point of my phone updated to lollipop but my imei has now gone back to square one. Nonetheless at least I have Lollipop

Samsung Galaxy SM-G928X stuck on startup screen!

I have been trawling the internet for literally hours.
This is my final hope before I get really desperate with this device.
I bought a Samsung Galaxy Edge+ online as a demo unit so I could use it as a glorified tablet,
since it was a demo unit it had demo software which I tried to remove using the 5444 password
trick on the retail software to no avail. So I decided to root the phone using Odin and the
SM-G928 F/I/C/K/S software as i couldn't find the particular software for this phone anywhere.
This worked but every time I booted the phone it would give me the 'KERNEL IS NOT SEANDROID ENFORCING'
on the top left of the device which I promptly ignored and continued to use the device, I downloaded
root check which said my device was rooted and then I downloaded system app uninstaller to try remove all the trial
software, which unfortunately didn't work. I then attempted a hard reset, which also didn't work and just
rebooted the device, finally i decided to download Flashify and TWRP recovery to try and delete the trial software
from there. At this point I was just messing around with the phone when I noticed a thread that said i needed
titanium backup to fully delete the software, so i rebooted the phone and it has been stuck on the bootup screen
ever since, I have tried several methods to get it to work including re-flashing the software onto it,
(the SM-G928F one I mean) but i simply cannot find the correct one for my device.
Any help would be greatly appreciated :good::good::good::good:
The device is running 5.1.1
I am not sure of the kernel or anything like that as I am quite noobish.

First thing to do is to get into STOCK recovery and do a "Factory Data Reset"
or you can boot the phone up and go into "Settings>Backup and Reset" and
select "Factory data reset".
After doing that odin flash the proper S6 Edge+ Lollipop 5.1.1 or the new Marshmallow 6.0 firmware.
You can see the exact model of your G928 phone by going into settings and scroll down to "about"
there you will find the specific model of your phone.
Be sure to ONLY odin flash the correct firmware for your phone's model.
Once you do all the above you will no longer see:
'KERNEL IS NOT SEANDROID ENFORCING'
The only reason you see that is because the phone is rooted.
After odin flashing the proper firmware your phone will no longer be rooted
unless you root the phone again.
Good luck,
Have a great day!

I can't boot the phone up, if I could I would, I can't find the software for this particular model, which is aforementioned SM-G928X,
If you could help me with that, I would appreciate it. The phone is stuck on the Saumsung boot up, it doesn't actually boot up into
the lock screen so I can't do anything with it, if you could help me with link to the SM-G928X firmware that I could use in ODIN
that would be greatly appreciated cause the phone is a paper weight at this point.
I had a moment of madness and decided to do what you said anyway, and I can't factory reset the phone from the recovery menu as it says
its due to security policies or something of that nature, which again I mentioned in the initial thread.
Also to clarify, I can't flash my own firmware because I can't find the firmware anywhere on the internet.

I have done a bit of research on your G928X device and I think you are in luck.
Check out this link carefully http://pdadb.net/index.php?m=specs&id=8759&c=samsung_sm-g928x_galaxy_s6_edgeplus_lte-a_samsung_zen
and you will see that the firmware in your phone is identical to many other G928 firmwares as you will see in that link.
Odin flashing any of the ZEN firmwares in that link cannot brick your phone, the worse thing that can happen is that it will not
work. (just like it's not working for you right now).
I would go a head and odin flash the S6 Edge+ G928T firmware which is also the ZEN baseband firmware, there are many S6 Edge+ phones
using the exact same firmware. All Samsung S6 Edge+ firmwares contain the modem but not all of them will be compatible with your
carrier but at least you will be able to boot your phone normally without getting stuck on boot screen or bootlooping to start with.
You can get the G928T firmware from http://sammobile.com OR
https://www.androidfilehost.com/?fid=24499762636004597 (fast download)
Good luck,
Have a great day!

Going CRAZY trying to restore S7 to factory

I wiped my girlfriend's S7 for Sprint (SM-G930P), in order to run tools to try and recover deleted internal saved voicemails. (Which I never could find). She wanted it unrooted. Can't remember what I did, but now the phone won't boot. I think the recovery is screwed up.
I had originally started with this post....
https://forum.xda-developers.com/sprint-galaxy-s7/how-to/root-firmware-qg1-tweaks-mods-t3654700
At the command line, ADB does NOT see the phone.
I tried calling 10 different numbers for Samsung, no one could help me.
Kies and/or Smartswitch Emergency Recovery requires the serial number, which I do NOT have.
Everything for rooting went well, but now when unrooting, I get the "unauthorized software, please contact service provider screen" or 'sometimes' I am able to get to the bootloader screen.
I don't know which version of Odin, which firmware, whether it should be separate AP, BL, etc, or a single file.... Rooting never used to be this difficult before locked bootloaders. I'm literally pulling my hair out because now I need to spend $250 to go buy my GF another Sprint S7.
I've tried this post also, with NO luck....
https://forum.xda-developers.com/sp...g930p-bricked-root-attempt-stock-rom-t3715222
ODIN = FAIL on everything. Although Odin does recognize the phone. Please help.

So Odin does recognize the phone in download mode? Then you should be able to restore it. Are you using the special version of ODIN for the S7? When you boot in download mode, read the firmware version 5 characters back from the end. Does it say 4 or 5? I would completely reflash the firmware. The latest firmware will probably do the trick, but it will update the binary for the bootloader, but it is better than buying a new phone.

No voicemail notifications S10+ no root

Just got the S10+ yesterday. No root and no plan to root at present (it's my husbands phone and he's weird lol)
His voicemail isn't giving him a notification. Nothing on the icon on the home screen and nothing when I open the app. I've cleared cache and data, app is up to date, rebooted phone, searched sprint and searched XDA and can't find an answer.
Anyone have any ideas what I need to do?
Have you tried updating the phone via the OTA updates? You might need to do a factory data reset or flash the latest stock firmware with Odin if all else fails.

I'll double check to see if an OTA was done or not. I was thinking my next step would be to do a factory reset. Weird thing is my note 10+ doesn't have VM either. It's not activated yet so I didn't know if that could be why.
I also tried to download the app from the play store (on my husbands phone) and it would get to downloading 2%, say it was installing then give an error of "this application cannot be installed"
Sounds like you need a factory reset and if that fails reflash the firmware with Odin. I have voicemail on my S10+ here running the AT&T firmware. Some firmware like Version or others might have visual voicemail. I have the icon for it on my phone, but never use it.

[SAMUSUNG GALAXY A41] - Imei Repair

Hello everyone,
I explain you my problem:
I tried this morning to update my samsung galaxy A41 SM-A415F rooted with Magisk (firmware patched via magisk) to the latest version (A415FXXU1CUH2) that can be seen on sammobile :
Download Samsung Galaxy A41 SM-A415F XEF France A415FXXU1CUH2 firmware​
So I tried to update the phone by setting the HOME_CSC to odin but what was the surprise when the phone rebooted? Some partitions were corrupted and I had no choice but to reset the phone.
I wanted to reset the phone with the last ROM and so I started the installation on odin BUT I checked the option "Nand Erase" and "Re-partition" and since then the IMEI number has been deleted and I can't put it back nor send messages / calls etc.
I have searched everywhere on the internet and even trying to put back the last ROM doesn't work and when I want to do *#06# the message: sm-a415f is not supported on showIMEI is displayed
After a while I found a tutorial on the internet that said I had to put the .pit file of my rom in the "PIT" tab on Odin in addition to my ROM because I had deleted all the partitions of the phone... I checked the Re-Partition option in addition to F. Reset Time & Auto Reboot to register the .pit but it didn't work, I always get 2 errors: One when I reset the phone before the menu with all the apps is displayed telling me: "IMEI or MEID is empty" and another one when I try to see the IMEI number when I press *#06# in the phone app telling me: sm-a415f is not supported on showIMEI
I thank you in advance for your help,
Sincerely.
Edit:
Oh yeah, and the phone doesn't detect the sim card even when I take it out and put it back in...
Hello,
i also have a similar problem.
I rooted the samsung A41 smartphone with magisk. After a while, I wanted to go back and put the original firmware back. Everything worked until I installed update A415FXXU1CUH2. Now the IMEI is empty and the sim card cannot be used. I went back to the A415FXXU1CUD4 version and now everything works fine. I initially blamed all these problems whit the root, but looking around on web I saw that the IMEI problem happens.
Can't read SIM cards after the latest update
Hello, I received and installed a firmware update two days ago. I noticed cell signal icon was replaced by a crossed circle; . Also, the options for 4G and 5G are nonresponsive, the menu options are not greyed out but they are unresponsive when pressed. So I can't connect to my cell service...

Samsung A21s software update problem
After the last update.. I have lost my connection to 3g/4g ... my phone only connects to my home wifi... but doesn't connect anywhere else. Any advice?
eu.community.samsung.com
Problem: IMEI is null after updating to A415FXXU1CUH2. Cant call, message or use data.
Solution: Flash earlier firmware or restore from your full backup.
I confirm this IMEI problem and that the @Arazon´s solution works.
I tried to update the phone to the latest stock firmware Android 11 (A415FXXU1CUH2) from an earlier version. I got everything to work except the IMEI showed null. I tried flashing with both root and non-root. I tough I had broken the EFS-partition but luckily that was not the case. Somehow the IMEI could not be red with the newest firmware. I guess Samsung needs to fix it and we have to wait for a few months? Anyways I will try updating the A41 "the normal way" and then flashing my root after that. Maybe it will work.
I wonder when we get the unofficial LineageOS for the A41 SM-A415F. Hit me up if you are up to it, I might be able to help.

I tried updating the A41 with bootloader locked but the results were the same. It seems that if you have tripped the Knox (voided warranty) the recent update A415FXXU1CUH2 will somehow break your imei and it will show up as null.
These firmware versions (root or non-root) do work and the imei problem does not exist even with tripped knox and unlocked bootloader:
A415FXXS1CUG1
A415FXXU1CUD4
A415FXXU1BUC3 and older
