So I installed KingRoot for an app so I can retrieve some deleted files that I have deleted by accident. Then I had no use of it, but forgot to uninstall it before my phone discharged. It had the usual start up screen (Where it says “Samsung Galaxy Grand Prime” & “Powered by Android”) but it had a lock symbol that had the label “custom”. Then it cuts to a screen, in red, on the top left corner, it says “SECURE FAIL KERNEL” and in the center it says “Security Error: This phone has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair/return for this issue may have additional cost.” Someone please help, this is the first time this has happened and this is my first phone. I don’t have a warranty so I can’t take it back to my provider. (My provider is Cricket)

Hi, I have this team that suddenly did not want to turn off and on again, trying to turn it hangs on the screen Samsung Galaxy Note 3 SM-N900 and does not advance. Just enter the DOWNLOAD mode, do not enter recovery mode (likewise hangs on the Samsung Galaxy Note 3 screen and not initialized). We try downloading the software with ODIN 3.04 and 3.07 and programs reach only as far indicates initialization ... Finally the battery charging equipment off as if nothing happened even LED lights. What to wear to an authorized Samsung service in which I indicated that the logic board is damaged, as there is satisfied. Therefore before opening the computer to change any component or request assistance from another technician would like to know your comments about this problemon. The software version I had was the 4.4.2. If I remember these were the data that appeared in about phone: PDA: N900UBUENH1 CSC: N900UUBENG1.
The only strange thing was that I had installed> HD Pro Battery Manufacturer> smallte.ch program
Additionally I had saved in the internal memory a film almost 1 GB. The rest was on the memory card which scan with an antivirus with license and was virus free
I really appreciate all your help and comments:crying::crying::crying:
Reboot in DOWNLOAD MODE and make us a photo pls.
Hello,
I use Samsung Galaxy S5 a year and less. Friend of mine brought it from the US. It’s unlocked with a code. The device is TMobile. A few days ago I used it as Hotspot router, to share internet to my laptop. I restarted the phone, but not turned off the Hotspot. When the phone is switched on, displaying the following error: "Secure Fail: Modem ...“in red letters, top left and in the middle - exclamation point in a yellow triangle, and below it the inscription in white letters: "Security Error: This phone has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair/return for this issue may have additional cost". I tried to flash with Odin with different ROMs for model G900T. It gave me PASS all times, but the error still comes and the phone does not start. I gave it to a friend who has GSM service. He said he made 6 service flash and nothing. He tried flash with stock ROM and 4 fiels+pit, but nothing. I tried different tutorials from here, but I am not quite good and not sure I do things properly. I dis flash with this CF-Auto-Root-kltetmo-kltetmo-smg900t. Again same error but I had a different boot menu. There did a few cash and full resets. After that the phone started and stopped on Samsung android advertise. I flash with stock ROM after and again same modem error. I am from Bulgaria. I called to local Samsung service. They refused me to see the phone because they are not authorized. Have to repair just in USA, but this is complicated. Any idea what to do? Please, give a few tutorials to repair this!
Thanks in advance!
Please, you could give me threads which contains thing I have to do to repair my phone. No problem if I have to do few things. Important is to try everything possible again and in wright order.
Here's what I did...I used an older phone to download my modem to since my laptop was down at the time...I then booted into TWRP recovery after I've inserted the extSD card and from there I used TWRP to get modem back..hopefully I understood ur question and this would help you..sorry if it doesn't!

So I am actually not sure what happened to my phone, at first it did not want to go through the Samsung S5 NEO powered by andriod logo, It said custom binary blocked by frp lock in the top left corner. So I did some research and first I found that using Samsung Kies I could fix it but when I put my sin number in it keeps on saying: "please check the model name and s/n and enter them again". So I did some more research and found out my best bet is just to load a rom on to my phone so I got it into download mode, Power+Home+VolumeDownButton and found my phones andriod 6.0.1, The exact andriod that it currently has, I started the process of it sending it to my phone and then when it was done it rebooted and started saying "An error has occurred while updating the device software. Use the Emeregency recovery function in the Smart Switch PC software. When I put my phones model name and s/n number it again says "please check the model name and s/n and enter them again". I am not sure what to do anymore, I can do nothing with my phone anymore. Is there anyway to get it working again? and hoviously my warranty is voided, but it was exipred by now because I have had the phone for a good 3 years if not longer by now.
Okay so i tried the SamFail Rom / Root. 5 seconds into the root i got an error, a PIT fail code. The phone which is a carrier unlocked one went into an infinite boot loop on the recovery screen, and wouldn't let me enter the recovery options. I tried many hard resets, took out the battery, and even let it drain but nothing helped, it would just boot loops into the downloading update / Error . After all this i decided to try to flash the original firmware into it. Only thing is i didn't write down the software version. But since i have t mobile i thought why not just flash it with the latest tmobile software. So i did.
Now the phone turns on and everything works but it wont connect to the network. IMS registration status is not registered, Mobile network state is Disconnected but it does say T-Mobile which is my carrier.
Under the Odin download mode, before i even flashed it at the top left under carrier IT said SPR so i figured the phone was originally a sprint phone then unlocked and sold by the company. so i also tried the SPRINT software but same thing happens.
Under Co figuring Service it just stays registering then says " Please contact your service provider....." internal error -1.
Under UICC Unlock it says Your device is unlocked for any SIM card but then when i click it, it says SIM unlocking could not be completed please try again later. Internal Error 407.
Any help or insight would be appreciated. i don't care about the root anymore i just want the phone to work normally, Thanks.
---------------------------------------------------------
:Edit - I messed with it enough now it shows LTE service and everything but the. SPRINT OMADM Message wont go away. And the Carrier Hub - Requests are processing wont go away. also i get very minimum service if any at all. . Any help? Thanks.
Click on settings app->apps->click 3 dots button at upper right corner->click show systemapps-> search Sprint OMADM app and force stop it
Hello
My Samsung Galaxy Note 5 was recently FRP locked. I removed the lock by flashing the firmware through Odin. I am not a professional i just did that by following YouTube videos.
Now that the phone is working but once the phone boots up a message is displayed
"Security Error
This phone has been flashed with unauthorized software & is locked. Call your mobile operator for additional support."
The problem now is that the sim card is not working although it was working perfectly before flashing.
I am using a T-Mobile(SM-N920T) Samsung Note 5 and i used the latest firmware from Sam mobile for flashing my phone.
Can anybody please help me what to do now?
I am stuck right now and don't Know what to do. I want my sim card working.
Thank you Your help would be appreciated.
