[Q] get rid of a spy monitoring software on my gt-i9505

hello everyone
i am quit sure about 99999% that my gt-i9505 has a spy monitoring software and i want to know the steps to follow to get rid of it.
i think one night when i blacked out ( too much alcohol) , they installed it on my phone , when i woke up i found the phone with the sim blocked ( needed the puk to unlock it again) . and since then ,they are monitoring my line video calls and audio calls because some details of my conversations with my mom are revealed by some unknown folks that live nearby.
yesterday i flashed with odin the new uk lollipop official rom for the black edition but it seems that they can still monitor me .
is there any definitive guide to follow to get rid of any spying software.
i would really appreciate any help:laugh:

Hello,
Since you flashed stock ROM (this basically wipes all the internal data such as operating system, contacts, messages, photos, videos, music, installed apps...everything) if before you had a monitoring software inside now there isn't anymore

maybe they are good at hacking and have put the spy monitoring thing on your sim card lol. but i'm sure everything got wiped since you flashed the latest official version.

If after u do update via odin and not full wipe. The software MAY not gone. Say the app is installed as user app. Then it now still active

A normal procedure trough Odin never does that. It never wipes anything. Maybe with .pit and repartition (not sure).

Won't antivirus software detect it as a spyware?

Hi mate ,
Do a factory reset and as @ Lennyz said adding PIT to the equation will wipe everything....if you have a custom recovery you could format system , format data...and format internal SD then you also could flash a custom or stock rom afterwards....

You're right mate, I forgot I always use Repartition when reflashing (habit! :good: )
In my opinion, he should definitely try to repartition or at least make a wipe data/factory reset from recovery
Inviato dal mio GT-I9505

thank you for your help
you are suggesting that i reflash the stock lollipop 5.0.1 using odin v 3.09 for example ,and check the repartition ? even if i have only mds file? this could brick my s4?
if i want to use a pit file where can i get it? i have the snapdragon version of the gt-i9505(i only flashed it once with lollipop 5.01 of the black edition from uk) the official rom i used is the one availale in sammobile
nota: after flashing the lollipop rom y wiped data and cache . but even so they are tracking me

ok guys here is a very strange thing that i came across
i did flash the pit ,ap ...... lollipop 5.0.1 but when i power on the phone without the sim card , guess what??!!!! i dont get the no sim card icon and i get full network signal on the phone
really really strange , i those bad guys did a hardware manipulation or something like that.
anyone can help?

yes ,everything is working fine but even if i dont have the sim card , the phone doesnt show the icon of no sim is inserted , i think i wil get the phone to the authorities and see if they can find out if they cloned my sim card or modified the sim card tray or even they put some trojan into the phone , i am sure that when i power on the phone , they know it because i can hear them saying that , i think they cloned my sim or at least did some kind of manipulation

Mobile data stuck on EDGE

Hello everyone, i'm new to XDA forums and hopefully i'll find a solution to my problem here.
I am always stuck on EDGE (E) when it comes to mobile network usage, regardless of where i am. I've tried using my SIM card in another phone and it instantly goes to HSPA+ (H+).
My phone is pretty much new and i didnt mess much with it as i dont know enough about phones to play with them in that way, it has been like this ever since i took it. There is one thing that i think its most likely causing it and that is that my phone was rooted when i bought it. >>> I dont know anything about advantages/disadvantages of rooted phone and if this may or may not cause any problems but i've never had this kind of an issue before with any phone and none of my phones before were rooted. <<<
I wanted to try and unroot the device by using Mobile ODIN Pro from Google Play Store but i stopped before i even started as the PRO version that is needed for this to be done says my device is not supported and therefore i cannot buy it. I had the Lite version and there are like 4-5 features that require PRO version in order for them to be used.
I have a GT-I9505 running on 4.4.2 android version, i'm from Serbia with mts as provider for what it matters.
P.S. My network mode is set to WCDMA/GSM (auto connect), if i change it to WCDMA only i lose network completely and if i put GSM only its again back on EDGE.
Any help will be greatly appreciated.

Let's make sure you actually have an I9505. Try to enter download mode (shut the S4 off, then hold volume down, home, and power). The model at the top of the screen with the green Android on it is the actual model of your S4.

It is I9505 as i said. How do i leave this mode now? It says "Downloading... Do not turn off target !!" across the screen. :v

I strongly suggest you check that attitude of yours. Just because you said it doesn't mean it actually is. There have been too many instances of counterfeit phones as well as phones from another carrier being installed with I9505 ROMs and IMEI numbers and sold to the unsuspecting. The question is thus a valid one.
If you're looking to exit download mode, simply pull the battery. If you're looking to reinstall a stock ROM, then you're on the right screen. Simply connect your S4 to your computer and use the desktop version of Odin to flash the stock ROM. Now, how do you know which stock ROM you should be using? Simply tell us your carrier.

There is no attitude mate, i just told you that it is what i earlier wrote after checking it the way you told me to. Nothing more than that.
By carrier you mean my mobile provider or whatever its called? If so, Telekom Srbija (mts).

The latest ROM for your device is here. The page gives instructions on how to use the file as well as download links.

Few questions:
Will that install lollipop? If yes, is lollipop worth getting? I recently heard opposite while i was actually trying to get it. It's the only opinion that i can sort of take in count so idk if its true or not.
Will it fix the problem?
"Add the firmware file to AP / PDA"
- What is(are) AP / PDA?
"Make sure re-partition is NOT ticked"
- This is an option in Odin i suppose, if it is disregard it. If not please explain.
Edit: I've downloaded PC version of Odin and i only see AP among other boxes for files to be added. Is PDA another name for it or..?
Should i also check the little box next to where it says AP? (picture below)
There's another zip file in odin folder "S1PlugIn.bundle_141117", i suppose i shouldnt touch this as you havent mentioned it?
P.S. Sorry if my questions appear stupid but i'm facing all of this for the first time and i'm just being extra careful as i dont want to mess up something.

This is the latest ROM for your device, so it will install Android 5.0.1. I believe it to be worthwhile, but if you want Android 4.4.2 instead a download is also available for it at the same site. Will it fix the problem? It should. If it doesn't then a hardware problem is more likely.
AP and PDA are two different names for the same thing. Older versions of Odin used PDA. Checking the box next to it won't hurt, and that other file isn't something you touch.

So i need to turn off my phone, go to download mode, connect pc and phone with USB, wait for some "blue sign" from ODIN and then add the file and run Start? Re-partition is disabled by default.

Everything went smooth but the problem persists... I even changed the network mode to the new options that i got (which includes 4g if i'm not wrong).
What to do?
P.S. 5.0.1 runs really slow for me, takes double more RAM than 4.4.2 and it almost filled up my whole phone memory

Try a different sim in your phone. if you still don't get 4g then you probably have a hardware failure.

Aye... Still the same even with another sim card. I guess its hardware problem in the end. Any idea what would it cost to fix, if you know what the problem could be at all?

New flashed rom has things I never had

Hi guys!
So I have a S7E 935F unlocked.
I tried to root the device and did everything as written and shown in every tutorial but it failed to do so.
After flashing recovery TWRP and trying to flash SuperSU the device just got into a boot loop.
I was reading around and understood that this is a problem due to encryption of the FS.
So I downloaded my firmware from sammobile and flashed my device again, everything got back to normal.
Well, almost normal. The rom I have has the same build number, version, kernel, everything is the same as the original one only that I have things in the settings menu I never has, like I have "apps" twice, one for apps permissions etc and one for apps manager, I also have "T roaming" no idea what it is, never had it, I have "service provider KT twophone".
Also the settings app crash a lot, browser gets stuck a lot, can't change system language to English (app crash).
At the home screen I Samsung Pay which I never had and I have some sort of a news app integrated on my home screen and it's marked with two stripes.
I verified this is a global rom for my country, not by any mobile company as before, I really don't have a clue what to do.
Can someone please advise?

T roaming and KT twophone service are both from korean carriers, maybe you have a wrong CSC installed or your /efs/imei/mps_code.dat is messed up.
Try to download and install the latest firmware of your region using Samfirm and if it still doesn't solve the problem, open up /efs/imei/mps_code.dat and see if matches your region name.

OK so I D/L the firmware again and same thing...
I checked /efs folder and its empty, maybe the content is hidden? Anyways my device has its IMEI and I can use it to make calls... thoughts?

You need smart switch on your pc, enter your imei number in smart switch and it will download correct firmware according to your imei, then flash it. Good Luck

Hello, this smart switch method is obsolete. Use odin to re-flash your stock rom in case of any issues. Be sure to use correct and matching binary firmware.

Note 4 N910C Emergency Call only (Not Registered to Network) IMEICERT:PASS (IMEI Ok )

Greetings Folks
I have a N910C and as mentioned in title recently I got stuck in to this issue
How it happened
I had CF-Rooted my phone and Odin flashed TWRP for custom ROMS so I tried a few and was not getting the perfomance thought SimplROM would do it for me in order to install that ROM it said in instructions to install latest Modem and Bootloader
So i tried downloading the ones given in v6C BL was downloaded but CP kept on giving me errors getting stuck at 7% on mega so being stupid I downloaded DPCB(MODEM) While ROM was offering DPK4
So everything went fine until after boot I realized am facing Not Registered to Network
Since I had experienced this before on other phone I went ASAP in dialer to check my IMEI & SN both are still intact
I knew about EFS unfortunately I backed it up on Phone Storage which was wiped for ROM and I forgot (So dont have EFS Backup )
I do recall years ago back when I had S3 I experienced this and sometimes flashing different firmware(CSC ,Modem) fixed it
What I have tried so far
I have already tried several stock ROMs most of em had DPI1 Baseband except 2 other ROMS no luck
tried combination file method too (the one that helps downgrade to kitkat i believe ) no luck
Tried XEO repair Firmware no luck
any suggestions ??
and on that contrary now that I am not on stock is there any way to find out which CSC and Stock ROM this phone originally was one or came with with IMEI or Serial I believe ?
Thanks in Advance

Anyone??

under the battery there's the serial number
install on your pc samsung smart switch program
run it with option of emergency software recovery - device initialisation
input the model of your phone
input the serial number
start
have patience and a good connection
your phone will (eventually) get the latest official firmware
https://www.blogtechtips.com/2017/06/24/easily-restore-samsung-device-firmware-with-smart-switch/
at least you'll have a working phone with stock rom
from here on you can try again and get informed better on what to do
good luck

Hey there bud I have almost tried most of fixes I could I'll give Smart Switch a try as I recall I checked before it didn't have initialization just the recovery mode, while in Kies 3 I did try initialization method by model and SN but it prompted device doesn't support initialization
Anyways do you think it could fix network?

Maybe restore the efs from recovery, if you have a backup that was working.

Jist checked not getting initialization option on smart switch ill see a work around it if its a version thing , as for working backup I lost it mate it was in twrp folder in phone storage it got wiped recovery softwares out there only help recovering media mostly if mass storage mount was option could have tried recovering for PC but that has been long gone since ICS

Yep. Same problem as mine. Im kinda lost now since i dont have anything; even in stock rom it cannot go beyond connecting to my carrier. It only able to read my contact.
Im guessing its a motherboard problem? Isnt it @w41ru5?

I don't know. Usually it's a modem issue when not recognizing the sim.
If it's a 910F snapdragon it might be the infamous eMMC issue.
If you have an EFS backup try to restore it from recovery TWRP.

Assuming its modem problem, its related to motherboard i guess, right?
Finally got the phone working, only to discovered that SIM not working. Really wasting my time and hype!
Plus, its hard to search for n910c replacement board here.

The firmware, not the physical one.
Did you try to flash the 4 files repair firmware?
This is an example, I don't know what phone you have
https://firmware.gem-flash.com/index.php?a=downloads&b=folder&id=7081
Did you try the SmartSwitch pc program?

"...4 file repair..."- what? Ive google it until im almost run out of data here and you have a possible solution? You must be active in note4 forum.
One thing i noticed that, the IMEI and Serial Number are different from the sticker included.
I will try it, but not immediately; waiting for thurday-friday for data renewal.
My phone is n910c
EDIT : just checked the page you gave. I have few question;
What should i do with the files? What are the step? What are the program needed?
Is it related to SmartSwitch as you mention; need to use it?
Thanks!

1. It's good you still have the IMEI. Not so important if they're different from the sticker. Where did you buy the phone from?
2. So if you go to check the 4 files repair, you need to search on that site the files for a 910C.
3. Did the phone worked on your country provider? If yes, maybe you need to search for the 4files corresponding to your region code.
4. These 4files have to be flashed with Odin
https://zfirmware.com/download-samsung-repair-firmwares/
5. SmartSwitch is an alternative to get the latest firmware for your phone according with the model and serial number.

the "firmware.gem" are useless. the error says i need another package (i assume a quota) to download the needed files.
im currently testing "zfirmware", but have a doubt since it only give 1 type file (which country is it i dunno). but yeah, since my phone like that, it wouldnt hurt to try
EDIT : yep, nothing changed. the device not even bricked.

I tried files from LP and MM. It didnt work. And also smartswitch.
I was hoping that it will brick the phone (if i ever missed a step or incorrect file) but it didnt.
Might as well try looking for replacement board (or even a refurbished note4).
Thanks though for the suggestion @w41ru5!

Greetings again folks reading your replies above I have been trying almost every fix there is out there
First of all about Emergency Calls Only/Not Registered on Network
It can be due to several causes its can be Hardware ie faulty modem
it can be bad network coverage
it can be bad simcard
it can be SW with EFS problems or maybe even on rare occasion a modem file that you flashed
EFS can be either bad IMEI with CERT : FAIL or Just Network with IMEI and SN intact
just dial *#0011*# and see if you have CERT : PASS ( also someone with good IMEI/CERT and working network can share screenshot so i can compare whats wrong)
I am certain mine is EFS related because it happened after flashing modem DPCB modem via ODIN (I had TWRP EFS backup but the blunder I made was backing it up on phone storage and being careless forgot it was there and was wiped for custom ROM flashing process)
So far what I have tried
Combination File Method (and even downgrade to KK 4.4.4 )
Repair Firmware that include AP,BL,CP,CSC and even PIT
Kies 3 or Older Smart Switch says (Device doesn't support initialization ) since initialization feature was removed by Samsung on newer Smartswitch(since it was being used for wrong reasons? read somewhere)
Several different firmware's
OTA update
My IMEI CERT says PASS if only we had a network patch like Ariza Patch (for Galaxy S3) for Note 4 then we would be in luck so far at this point I dont think flashing ROM's would even help with bad EFS our only luck is Box e.g Z3x or Octo dont know if we are allowed to talk about those here (ill edit post if not)
these box applications have Network Patch for most Samsung models but I don't see one for N910C in most versions
for those with bad IMEI they can try writing good cert or efs on note 4 since they have already lost it I am sitting on it because my EFS is good on that part and for some reason box app isnt allowing me to back up my CERT if I am able to back up current cert then ill give those a try but I would prefer current IMEI since in my country IMEI should be verified to use the phone or you have to pay tax
I know its Bad EFS for sure because using Box application I chose reset EFS(after backing up current faulty EFS with good IMEI) upon reboot phone's imei was changed with no SN network came back for few seconds then gone again ,this happened to many users that have tried resetting EFS so I restored my original EFS
if anyone here with N910C and root can give me EFS folder I can corelate if any file required for network is missing since i have good IMEI
Cheers!

Advice on S7e Firmware from UAE to BTU

Hopefully you guys might take a mo whilst we are in lockdown to just give me a few pointers please
Original S7e screen bust 6 months ago so i purchased a rekon S7e from Amazon Uk, all seemed well and i re applied my backups from my old phone to the replacement phone, after a few days of getting the phone the same as the original i realised the phone had a UAE csc, annoying at best but as i needed a working phone i kind of let it slide and carried on using the phone, apart from Samsung Health showing UAE adverts and pay showing UAE info the phone seemed ok.... actually add to that it has recieved no updates since Oct 2019 either, i have tried all ways to get security updates and phone os updates but to no avail, it just says it is up to date which i know is wrong as security updates have been released since last year
Now in lockdown and its raining its time to hopefully get the thing back on track, could you guys advise on what exact files i need so i dont brick or trip knox please
dev mode no issues
usb config no isuues
i have grabbed the latest UAE files
i have grabbed the latest UK BTU files
odin installed
do i need to mix and match files from both downloads ? just use the BTU files ?? if you guys could please give me some info on which set of files i need to load into odin it would be much appreciated
if you need csc pda numbers no probs just shout, i have never messed with android firmware before, all i want to do is get a Uk updating phone again
Thanks if you can help and stay safe

Well, there is a saying which goes like this ;
"Don't try to fix which isn't broken"
You can make calls.. your phone works in all aspects.
Except that you dislike some uae built-in apps
Just disable those apps..
But if you have decided you want to jump in the "pseudo effect of update feels good" ship .. then i can't stop you.. its ur phone
But trust me you WON'T WANT TO HAVE LATEST UPDATES because i did what you want to do and now suffer
Okay but if you want to flash latest rom for your current country follow these steps.
1. See which rom/firmware is currently installed in your phone .. i.e : build numbers , and copy paste them here and also note them down so you can remember..
2. Since you want to get in this ship you need to ENABLE OEM UNLOCK AND USB DEBUGGING IN DEVELOPER OPTIONS, just to stay safe ** i will tell you why later **
3. Download latest odin from here i.e 3.14.4 https://technastic.com/odin-download-samsung-latest-all-versions/
4. Download latest firmware for your current country from here :
https://www.sammobile.com/samsung/galaxy-s7-edge/firmware/SM-G935F/BTU/
(if it is uk then there are 2 csc for uk .. btu and xeu)

Thanks Shah
Yup it definately is a second hand phone, the rear o2 blood sensor has a very dim red light on all the time, i read a software update cured that ?? which is another reason i wanted to try and get the phone to update
what does concern me, how can i tell if the phone has patched certs or IMEI ?? is there a way of finding this out ?? that does appear to be the only thing that at present i cannot find out
If any of this helps i would appreciate you taking a look

Well, there is a saying which goes like this ;
"Don't try to fix which isn't broken"
You can make calls.. your phone works in all aspects.
Except that you dislike some uae built-in apps
Just disable those apps..
But if you have decided you want to jump in the "pseudo effect of update feels good" ship .. then i can't stop you.. its ur phone
But trust me you WON'T WANT TO HAVE LATEST UPDATES because i did what you want to do and now suffer
Okay but if you want to flash latest rom for your current country follow these steps.
1. See which rom/firmware is currently installed in your phone .. i.e : build numbers , and copy paste them here and also note them down so you can remember..
2. Since you want to get in this ship you need to ENABLE OEM UNLOCK AND USB DEBUGGING IN DEVELOPER OPTIONS, just to stay safe ** i will tell you why later **
3. Download latest odin from here i.e 3.14.4 https://technastic.com/odin-download-samsung-latest-all-versions/
4. Download latest firmware for your current country from here :
https://www.sammobile.com/samsung/galaxy-s7-edge/firmware/SM-G935F/BTU/
(if it is uk then there are 2 csc for uk .. btu and xeu)
5. *Important* make a backup of everything in your phone, then turn it off and go in recovery mode (by holding vol up + home + power buttons while its off)
Factory data reset and wipe cache.. then turn off phone..
6. Then put your phone in download mode while its off (by holding vol down + home + power buttons)
7. Run odin as admin on your pc, extract the firmware file you downloaded earlier.. it will give 4 files .. BL , AP , CP , CSC..

Can you explain that a little further?
"BUT IF SOME CERTIFICATES/IMEI WAS PATCHED THEN YOU WILL LOSE NETWORK !!"
I have an SM-G935FD Galaxy S7 edge phone from Malaysia. I have it in Greece and as soon as I got it in my hands I let it go all the updates until Android 8. And then installed a custom rom. Since then I can't make or receive any calls and sometimes it recognize my sim card (Cosmote) and sometimes it doesn't. Even the times that recognize my network operator I still can't make or receive calls. And of course I don't have any data.
What I have done:
1. Flashed original Malaysian and Indonesian firmware with no luck
2. Activated and deactivated volte
3. Tried different sim card
4. Flashed original Greek firmware (which I thought it would solve my problem but nothing). At root files it has all the network operators enebled as normal.
5. Tried several custom ROMs from Android 7 to 10. The only one that had some result was Floyd 10. The result was that for a minute I had data and couple of sms came from missed calls. But then again nothing. And since the first time I installed it, when I reinstalled Floyd not even for a minute.
6. Tampered customer.xml file for csc folder as a friend from Floyd rom thread suggested but still nothing
7. With a different sim from different provider I have data almost all the time but no calls at all
do all that has something to do with what you stated above? because it pretty much looks like i ve lost network
Thanks

If you bought it second hand then yes, it certificates/imei may have been patched using a hardware box and reflashing or even factory formatting results in network loss.. it may only be fixed by a box (or a local repair shop having box)
The other reason can be that your efs partition got corrupted and if you don't have a backup of efs before you rooted/customized your phone then ur out of luck mate..
Even if you had efs backup you would have been still out of luck because you made the mistake of "updating" to latest binary firmware and we need combination rom to fully repair network issues (and combination roms are not being available/leaked online for latest binaries)
Also a box can fix this too (or a local repair shop having box)
Can you tell if your imei is displayed correctly and if its different from the one printed on the phone's back or phone's packaging ? (If you got any)

Both my IMEI and efs are alright. I'm trying all this time to find a way to patch the certificates because on the one hand I don't have 120euros top but z3x and in the other I live on an island in Greece where there aren't any Samsung repair shops. I found halabtech tool and I patched certificates with that but I'm not sure that it is ok for my phone. Anyway network didn't came back after that.
Anyway after I saw your post I searched a lot and in found done threads that say that only at Android 6 the certificates can be patched. Any help would be appreciated...

If you need to patch certs then your imei's aren't alright lol, your imei's are either changed or blacklisted which is causing the issues, and yes downgrading to android 6 is necessary for patching certs.. but i think you need a hardware box for that..

So if the IMEI is the same and not blacklisted then there is no need for the patch? I bought the phone from a friend of mine, who he didn't do anything to the phone. Not even the updates. When I took it I let it update to Android 8, flashed twrp and then an Android 10 rom. A process I have done a million times until now, just not on this phone. At no point I lost the IMEI. So although I don't have the packaging I'm pretty sure that it is the same. I checked and it is not blacklisted either.
Any idea what could be then?
And again thank you for your time

Yes, you can't verify that imei's are the same since you don't have original phone packaging, ask your friend to confirm..
And if imei's are okay then its efs bug/corruption, which i told in above post, you should have done backup before modifying phone.. but even if you got backup you cannot restore efs because you are on latest binaries and you need latest combination roms for successfully repairing efs, which sadly aren't available, so yeah sorry but hate to say can't guide further
Thats why i ask peeps to NOT get on latest firmware train lol and ALWAYS make efs backup before doing anything to your phone !
Btw, can you tell me which is the current firmware's build number ?

So i dialed *#06# and it shows both my imei and sn. This isn't a sign that everything is ok? Is there a way to test if my efs is corrupted?
I'm sending you screenshots of about phone to see my build and android version.

And the thing that troubles me most is that with a SIM card from a different provider I have data connection but no calls. Would that happen with corrupted efs?

So yeah imei may still be okay but you can't verify that this wasn't changed or such, by the looks of it its either a changed imei which lost its certs when reflashing..
Or a bugged/corrupted efs which isn't letting you connect to the networks.. and it can only be resolved as i said by combination rom and efs backup..
Since your binary is the latest 8th, there is no combination rom available for it
Btw you could try this guide here .. who knows it may work lol..

Nope, not by conventional means.. a hardware box .. possibly but still no guarantee..
Thats why one should always research before immediately hopping in the "latest is best" train.. because often then not, it isn't the best if not the worst

I'm flashing my phones since 2012. Never I had a problem like that. That's why I hurried to change rom. Anyway. Thank you for your help. You clarified several things for me. I think I'm going to try the above method you told me. The phone isn't usable anyway....
Thanks again
