[Q] PLEASE HELP!!! I think I am slowly killing my SPH-L720

So, let me tell you how this all started. I kept getting the update notification on my Samsung Galaxy s4 SPH-L720 to update to NAE from MJA. So I ignored it for a while and finally decided I should do some research into the possibilities of updating. BAD IDEA! I should have just left well enough alone. I HAD a perfectly working rooted, hotspot mod phone that worked good for the most part. SPRINT is horrible where I live so that was always frustrating and i read a couple things that upgrading may help service. It may have, I wouldn't know, my phone doesn't actually work anymore. So, I have done everything possible to this phone. I have flashed every update I could find, I have tried to change about every kernel I could find and nothing. It all started on Day 1 when I did the NAE upgrade, the first time it didn't take all the way things worked fine. So, I tried again and BAM, no WI-FI. You have no idea how miserable this made me, as I was hours away from going on "vacation". So, I tried everything I read on the internet about how to fix the Wi-Fi. Nothing worked. And as I kept trying new things, I was only compounding the problem. I tried to make an actual phone call yesterday and my phone froze up. I am getting a signal, so I can receive texts and email, but that is about it. I tried to flash Philz recovery and TWRP recovery but when I try to go into recovery mode the screen says "system software not authorized by Samsung has been found on your phone." When I go into download mode, the upper right corner says (in very small type):
ODIN MODE
Product Name: SPH-L720
Current Binary: Custom
System Status: Custom
Knox Kernel Lock: 0xffffffc
Knox Warranty Void: 0xffffffc
CSB_Config-LSB: 0x30
Write Protection: Enabled
eMMC Burst Mode: enabled
Also please see attachment for what my about screen looks like.
So my questions are, what do I do next? Do I try to go back to Stock ROM? If so, which one? Will it fix my Wi-Fi? Really, that is the most important part. Well, I would like my phone to work, but i think I will take Wi-Fi over phone. Thank you everyone in advance for your help.

If you never updated, I would ODIN back to stock firmware of MJA.
If you did update, just ODIN NAE. If you get a stock tar, you should be good.

Thank you

I odin'd back to MK2 stock and everything is fine. I have rooted it and now I am trying to figure out the Hotspot Mod. Any help would be great.
Thanks again.

There's a whole thread for the hotspot. Grab the correct zip file for either deodex or odex. Flash it and you should be fine.

[Q][noob] Note 4 N910F still with android 5.0.1

Hey guys
I may sound noob but the fact that my phone is still under android 5.0.1 drives me crazy (recent apps lag etc).
I've been checking for updates (OTA) but "Latest Updates have already been installed" message pops up.
I bought the phone from Cyprus (2nd hand) and as far as I am concerned it is fully stock (non-rooted).
Was my device supposed to receive the 5.1.1 update OTA, since other Note 4s in Cyprus were updated to 5.1.1 ?
Thanks!

Anyone guys ?

Was you phone rooted before? I am not sure of what i am going to say, but maybe if it was rooted you might not get official OTA. Turn off the phone, press POWER + HOME + VOLUME UP, and on the top left corner theres a Knox counter, check if it is 0x0 or 1x1. I am new to this phone and i have heard in some of the 2014/2015 phones if you root even if you unroot you won't be able to update via OTA. Hope it helps

That's incorrect even if you trip your knox counter you can still receive otas, your phone has to be fully stock however to receive the otas. If you go to settings about and software information your device status should be 'official'. Another way to check is to boot into download mode (Volume Down + Home + Power button) and check if all the system are official. If they are then you are good to go.
OTAs are usually released in waves so that might be the problem.
Anyhow you can manually update your phone using Odin.
Download this firmware file : http://www.sammobile.com/firmwares/download/56036/N910FXXU1COI1_N910FVFG1COH5_CYV/
Then extract it and put your phone in download mode and connect it to your PC then run Odin as admin. (Make sure Kies is uninstalled)
Put the file in PDA and flash the firmware to your device.

As i said i was not sure, nice someone showed up to help [emoji1]

First of all thank you for your time!
Device Status in Settings -> About is Official.
So, how can I make sure that this is the right Firmware to flash (as the phone was bought from Cyprus 2nd hand, and Im not sure if the other guy bought it from an other country in Europe) ?
Moreover, If i manually install the firmware file, as you stated, do I need to root the phone or something ? Or the device will be 100% official (its just that you install the update through the pc instead of OTA )?
It seems to be taking too long for the OTA, and that's why I was worried.
Thank you again!

The firmware is fully stock, untouched.
You do not need to be rooted to flash the firmware.
You can install this app on your phone and check your CSC

So This is what I get:

I suppose it is a Greek version. So, which firmware shall i download ? (There are 3 different firmwares : Greece, Greece Cosmote, Greece Vodafone. Greece has no 5.1.1 version only the latter two have.

Might I ask are you in the UK (Your current operator) If so you can attempt to flash the UK firmware.
If however you are living in Greece then you could flash one of the Greece firmwares and then flash a stock ROM (It will require a custom recovery, tripping KNOX counter) without the bloat.
The choice comes down to you, another last resort if you don't want to trip KNOX would be to flash a neighbouring country's firmware.

Basically I am from Cyprus but I'm currently studying in the UK. So what's the difference between the various firmwares ? I thought that only the one that is the same as the country you bought the phone is compatible.

Different country firmware can be flashed only sometimes it fails (nothing to worry about) in that case you might have re-package the firmware. Meaning you put the CSC from your country into the firmware.
Anyhow I would you to flash this firmware via Odin:
http://www.sammobile.com/firmwares/download/58473/N910FXXU1COJ3_N910FOXA1COJ3_DBT/
After downloading the firmware extract the file inside (using WinRar or equivalent)
A factory reset might be required to back-up everything from your phone as the internal storage will be wiped.
Uninstall Samsung Kies, install these USB drivers: https://www.androidfilehost.com/?fid=24052804347849220
Download Odin: https://www.androidfilehost.com/?fid=24052804347836222
Power down your phone, hold volume down key + Home key and power on the device. Press volume up to continue when promoted.
Connect your phone to your PC via USB.
Run Odin as admin and and put the extracted firmware file in AP and press start.
The phone should now reboot, let it do it's thing. If after around 10 minutes it's still at the Samsung screen.
Power off the device hold volume up + home + Power the device on and using the volume keys select wipe data and cache, then reboot.
Good luck, as always I must give the disclaimer that anything you do with your device is your responsibility.

Phone won't reboot after rooting (Samsung Galaxy J5)

Hello, um, I need a li'l help here
I just rooted my phone(Samsung J500H) and after it said "PASS" the phone is supposed to successfully restart but mine didn't. There are even yellowish-green lines on the screen. I used Odin(v.10) btw
I was about to try factory reset but I can't access recovery mode. Every time I try to it just goes back to the yellowish-green lines.
I can still access the download mode though. These are what's on the upper left of the screen:
Odin Mode
(Product Name)
Current Binary: Custom
System Status: Official
FRP Lock: Off
Knox Warranty Void: 0x1(4)
Secure Download: Enable
I downloaded Samsung Kies(I saw this tutorial on youtube on how he recovered his phone using Kies. There are a lot of comments saying it worked for them). It was fine until it asked for the s/n of my phone. I typed everything correctly and it would still end up saying "The S/N you have entered is incorrect". I even downloaded both Kies and Kies3 just to make sure and both has the same result.
That's it. After that I'm stuck. Heeeeellpp

Just download any country's firmware for J500H and flash it using odin. All country's firmware will work on your device as long as it is for J500H. Just dont use any other model's firmware like J500F.

I know sometimes if you let the battery go dead then after charge boot into bootloader, make sure you got a good tar file for your stock phone it may be a bad tar file if you are getting errors.

Hmmmm sounds like you accidentally flashed very old 6.0.1 firmware back when it bootloader version 2 (which they eventually updated to version 4 so you can't go backwards) so I would just completely charge the phone and go into recovery and do a facorty reset then try flashing the latest Sprint 7.0 firmware and you should be good

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)
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..
Select correct files corresponding to the boxes in odin..
*In odin options don't select any option other then F.reset time*
*USE CSC (NOT HOME CSC) IN CSC BOX..
8. Connect your phone to pc while in download mode (odin should detect the port.. if not install samsung drivers or smart switch for pc)
9. Press on start button to begin flashing.. once odin says success unplug your phone .. it will still be in download mode .. so hold vol down + home + power button to force reboot (once phone screen goes black immediately change from holding vol down to vol up + home + power .. this will put you in recovery mode.. do a factory data wipe + clear cache, then reboot phone)
**WARNING : DON'T UNPLUG YOUR PHONE WHILE ODIN IS FLASHING OR BEFORE IT SAYS SUCCESS ! **
10. Configure your settings and restore your data .. you should have btu csc now
*IMPORTANT*
*FLASHING A SECOND HAND BOUGHT PHONE (WHICH COULD BE PATCHED/MODIFIED BY A HARDWARE BOX) THROUGH ODIN CAN MAKE IT A HARD BRICK BUT IF OEM UNLOCK IS ENABLED YOU CAN FIX IT EASILY BUT IF SOME CERTIFICATES/IMEI WAS PATCHED THEN YOU WILL LOSE NETWORK !!*
*FLASHING TO LATEST FIRMWARE WILL CAUSE BOOTLOADER VERSION UPDATE AND YOU WILL BE STUCK WITH THAT BOOTLOADER (SINCE YOU CANNOT DOWNGRADE/FLASH ANY OTHER ROM WITH LOWER BOOTLOADER NUMBER OR EVEN TROUBLESHOOT USING A COMBINATION ROM*
*LATEST FIRMWARES HAVE SERIOUS PERFORMANCE/BATTERY ISSUES FROM MY EXPERIENCE AND YOU CAN DOWNGRADE ONCE YOU UPDATE TO A HIGHER BOOTLOADER NUMBER ! TRY EVERYTHING ON YOUR OWN RISK ! *

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

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..
Select correct files corresponding to the boxes in odin..
*In odin options don't select any option other then F.reset time*
*USE CSC (NOT HOME CSC) IN CSC BOX..
8. Connect your phone to pc while in download mode (odin should detect the port.. if not install samsung drivers or smart switch for pc)
9. Press on start button to begin flashing.. once odin says success unplug your phone .. it will still be in download mode .. so hold vol down + home + power button to force reboot (once phone screen goes black immediately change from holding vol down to vol up + home + power .. this will put you in recovery mode.. do a factory data wipe + clear cache, then reboot phone)
**WARNING : DON'T UNPLUG YOUR PHONE WHILE ODIN IS FLASHING OR BEFORE IT SAYS SUCCESS ! **
10. Configure your settings and restore your data .. you should have btu csc now
*IMPORTANT*
*FLASHING A SECOND HAND BOUGHT PHONE (WHICH COULD BE PATCHED/MODIFIED BY A HARDWARE BOX) THROUGH ODIN CAN MAKE IT A HARD BRICK BUT IF OEM UNLOCK IS ENABLED YOU CAN FIX IT EASILY BUT IF SOME CERTIFICATES/IMEI WAS PATCHED THEN YOU WILL LOSE NETWORK !!*
*FLASHING TO LATEST FIRMWARE WILL CAUSE BOOTLOADER VERSION UPDATE AND YOU WILL BE STUCK WITH THAT BOOTLOADER (SINCE YOU CANNOT DOWNGRADE/FLASH ANY OTHER ROM WITH LOWER BOOTLOADER NUMBER OR EVEN TROUBLESHOOT USING A COMBINATION ROM*
*LATEST FIRMWARES HAVE SERIOUS PERFORMANCE/BATTERY ISSUES FROM MY EXPERIENCE AND YOU CAN DOWNGRADE ONCE YOU UPDATE TO A HIGHER BOOTLOADER NUMBER ! TRY EVERYTHING ON YOUR OWN RISK ! *

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
