[Q] Cannot Flash Android 4.4.2 on GT-I9505 LTE

Hi everyone,
I flashed the leaked ROM I9505XXUFNA5 to my GT-I9505 LTE back in January when it came out, all went fine. However, now when I try to flash the official Android 4.4.2, say I9505XXUFNB8, via odin v3.09 the process will fail after 20 seconds and I have to flash the leaked ROM again in order to have a functioning phone. My phone is carrier free and it is not rooted.Can anyone help me please !
Thank you in advance,
MaximusDacicus

You just killed your EFS :/
You still got a chance:
you can stay with the leaked rom, but you will have to install the latest "modem" (included in rom failed to install) while you keep the romactually installed
thats the only way it can be lucky and may be EFS get back to work may be. I suppose you dont have any EFS backup, so if restoring it fails that way --> you will have to get it repaired. Will be at least 40$ i think...
There a many posts on xda about EFS, but once gone, it is gone. Feel free to read some hours about it

1. IMEI code is not messed up (it's the same as the one on on the package);
2. I still have carrier signal;
3. I can lock the sim card by pin code
Do you know other signs that would lead to the conclusion that the EFS file is broken ?

Carrier free it means that my phone it's not sim locked in any network. My phone is working fine. I just want to install an official ROM not to stay with the leaked one. I want to install the one for my country so that when I connect to samsung kies via PC the csc and pda of my phone to match up in order to receive updates or to simply for KIES to recognise my phone. The bottom line is that I find it strange that I can't flash 4.4.2 product code COA (Romania) I9505XXUFNB8.

what region is the leaked fw for?

It's from the Sammobile, It seems I can't post links.
Country more likely Germany

Thats due to its a branded rom you tried to install (COA = cosmote branded).
Here is the unbranded version you need (ROM = unbranded for your country):

CSC Code for BTU

I got a EE (EVR) Serial Number to flash onto my phone so I could have WiFi Calling, however I realised that I will have to wait a long time for Android 6 to come, or any updates.
Does anyone have an BTU Serial Number I could use for Smart Switch to flash back onto my phone please?
I tried using Odin to put BTU on, but I got a NAND Write error, and I had to use Smart Switch to put it back.
My phone came with BTU, but my Serial Number shows VIR for Virgin Media

Hi,
I doubt someone is willing to give up their serial to be honest, sorry.
Have you tried smart switch emergency recovery software?

How to downgrade from Nougat 7 to Marshmellow 6.0.1

How to downgrade from Nougat 7 to Marshmellow 6.0.1​
If you want to save the thing's you currently have on your device, then do a backup using Samsung Smart-Switch.. Because everything WILL be deleted!
First open settings and go to about phone then tap 6 to 7 times on the Build Number until you see developer mode activated. Then go back to the settings list and look for Developer Options and tap it. Now look for OEM unlock and turn it on. This step is important and NEEDS to be done or you'll have problems later, not kidding!! In the same list as OEM unlock, look for, and make sure USB Debugging is on.. Make sure you have no accounts on the phone before starting this( if you're not going to enable OEM unlock) delete all of them especially Google accounts! If you don't do this you can be locked out for 72 hours! Delete any fingerprints and lock screen pins also!! (Create your backup using Samsung Smart Switch or KIES or whichever you want BEFORE deleting any accounts!! Meaning LEAVE your Google account on the phone until your backup is FINISHED and THEN you can remove it.)
On a Windows desktop download odin(unless you already have it) and download firmware number N920VVRS3BPI1 from my Android File Host here ----> N920VVRS3BPI1 onto your windows desktop. If you use any other firmware besides the one I'm posting, it may or may not work so I suggest you use this one first.
After downloading the firmware shut your phone off (Did you make your backup and save your stuff FIRST? If not DON'T start this) and then put it into download mode by holding the volume down button, the home button and the power button at the same exact time (all 3 together). When the screen turns on immediately let go of the buttons and press the volume up button to continue. At this point odin should be open on your Windows computer, connect the phone and when you see it says added on odin you need to go into options and uncheck auto reboot, you NEED to do this! This is the only thing you SHOULD be ticking in these settings, do not tick on re-partition or anything else. Then go back and tap AP and select the firmware N920VVRS3BPI1 that you downloaded (extract it 1 time on your PC first) and after it verifies (odin might crash and say it's not responding on some systems, just leave it be it will finish and work again) then tap start and let it finish. When odin finally says PASS and you see successful 1/ failed 0 then disconnect the phone and immediately press and hold the volume down button and power button at the same time and when the screen comes back on select factory reset and after its finished the phone will reboot on it's own and you're done and booting back to Marshmallow 6.0.1.
If you don't follow these steps correctly you're liable to get stuck or something else and your phone is not my responsibility if you do something wrong and it doesn't work it's because you made the conscious decision to do it likely you'll have no problem with this if you follow directions!!! I did all the testing on my own Samsung Galaxy Note 5 Verizon model before posting this and did it several times to be sure it worked correctly.​

can you help me please with Note 5
can you help me please with Note 5
I have bought a Samsung note 5 from Dubai and it is working on my sim card at Egypt internationally for 5 months without problem.
I discovered that it is a Verizon modified to work internationally!!!.
However I was going to sell it and i did a factory hard reset to delete my personal data then the night mare began.
First of all the phone stuck at the set screen of accepting the terms and never reached the point where i can input my google email and password, whenever I accept the terms it get back to the first screen of language selection.
then i tired some pc applications to bypass the FRP lock but one of them made an uncomplete download which give an error and i can only enter the odin download mode nothing else ??
My question now is will your firmware N920VVRS3BPI1 solve this problem and let me use my local/international sim card line as before or shall it get me back to Verizon original firmware that is locked only to their lines ??

an update :
I have installed the firmware N920VVRS3BPI1 and it was amazing and working very well .... although it started with Verzion logo at beginning where i had a nightmare ha ha ha ... but after start every thing was ok and the sim card was accepted from Vodafone.

Just so you know you're using the wrong firmware on that phone because it's a N920F not a N920V that phone has an unlocked bootloader and can be rooted with chainfires root and it can pretty much accept whatever firmware because of the unlocked bootloader.

Thanks for reply
But does this mean that I can install firmware from N920C for example ??
And I can upgrade to Android 7 ?
And still my Sim card from Vodafone can be working without being locked ????

nope. This is a verizon phone. Just look at the baseband or bootloader. I have the same phone and it can be flashed by verizon firmware only..

Bootloader is locked. And there is not such model of note 5 like 920f. I don't know how sellers rename n920v to n920f... My phone now on official nougat QB9 and works flawlessly.

There is a F model it's the international one.
SM-N920F
And it says Verizon now because he flashed the firmware from my android file host account.
Personally I don't think the phones real because that F version usually means that it's a knock off from Thailand.

In Europe galaxy note 5 is N920C. F version is a Verizon version, just аltered by unknown way. N920F version never existed only as a disguised N920V. Just google it and you will see. There is no official firmware for "N920F".

I know but as I said the F version is usually a knock off from Thailand. Personally I don't even think it's real because if the bootloader is locked then how did they get it to say F? The only way to do that is to open the phone and change the chip inside because there's no way a real Verizon Note 5 would be able to do that.

So, you think these phones N920F are not good and I should sell it??, should I look for a new genuine one ?
I feel that the phone is working very well ?

If it's working fine keep it, no need to sell it if it's doing what you need it to do.

You should download something called phone info for Samsung so you can make sure the phone is real and not a knock off.. It should have the same exact specs a real one has and if it doesn't it's probably a fake one.

the phone info app is showing a real phone data ...... but when I enter the digits #*0*# it doesn't bring the test screen and the code *#06# doesn't show the IMEI .... is this normal for the Verizon phones ????

I may give this a go. Since receiving a replacement phone fr my original overheating one and getting Nougat update, this phone has been a pain...a real pain. Making phone calls activates the external speaker. I have to tap the speaker icon 3 times to get the ear piece speaker going then when call is answered it kicks back to the external speaker. Very fun in restaurants. Using Bluetooth radio while driving....forget it. Gmail will not download automatically. I'm about to go back to my Note 2.

Stuck in "odin mode". Help!

Hello. I recently bought a Samsung Galaxy S7 SM-G930F, but it said the firmware was modified in an unauthorized way. It showed the model as G930FD in the firmware but it's G930F on the back of the phone. I am guessing it was rooted. Then I did a cache wipe and it said the "FRP LOCK" wouldn't let it boot up, and now I am stuck in "odin mode". It says downloading and do not turn off target. The thing is I don't know the phone's country of origin so which firmware should I get? I don't wanna brick my phone. I live in Macedonia and I am downloading the Macedonia firmware at the moment but I don't know what to do next so please help. Thank you.

Just flash firmware for your country, if that doesn't work try flashing twrp and a custom rom. I'm not sure there is a way to tell physically wether it a F or FD maybe sim card trays are different, its pretty difficult to brick phone unless there is a hardware fault. Also have you tried Smart switch to install firmware, I've never used it but it supposed to be a good last resort.

It'll still boot into download mode due to FRP lock.
OT:
Use smart switch to restore your phone. You'll probably need information like IMEI and stuff for this. Do you have the original packaging?

Confusing galaxy s6 model

I got samsung galaxy s6
The problem is that i dont understand witch rom i should flash
At the back of my phone and the odin mode says that my model is Sm g920p
But the settings and also other apps such as device info and smart switch says that my model is sm g920f
I thought the previous owner of my phone has flashed a custom rom that changed my model but the confusing part is When i boot into odin mode the Binary says SAMSUNG OFFICIAL.
Please help me

When you're booting into Download Mode, there is an option to show you a bar code, pressing the home buttom. If the meid match with the Dec numbers down behind your phone, it's an 920p.

I have a customized ROM that says OFFICIAL, and a kernel that does the same... don't pay much attention to that. If in Download Mode, it says that the model is G920P, that's the model - doesn't matter what it says anywhere else.
You shouldn't have an issue flashing a firmware. Just flash it, make sure autoreboot isn't on, and restart it into recovery mode, clear cache, system reboot and that should be all.
