[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):

model different to firmware

Hey All,
Just bought a second hand s6 g920 and the back of the phone says g920F but the software on it says G920p. How can this even happen and how can i fix it?
i'd rather have g920F firmware as that is the international one and has more xda community support.
thanks in advance

Same problem... can anyone help?

DOWNLOAD FIRMWARE OF SM-G920F from sammobile.com and flash it thorugh odian. it is quite easy.

most likely the previous owner has damaged the phone and back glass was replaced.

Put phone in download mode anf check the model number (it cannot be changed ).. Its easy .. Just use a little your brain...

Lost IMEI and baseband numbers after flashing custom software. Help with restoring.

Hi, I flashed xtrestolite on my phone and after booting up both my imei and baseband numbers became unknown; I now can't connect to my mobile network as my phone doesn't detect my sim.
I've tried to fix this issue by flashing other roms as well as flashing various official firmwares downloaded from sammobile to no avail.
I remember having the same issue with my gs3 and fixed it by flashing cyanogenmod. I tried this as well but the phone wouldn't boot up after flashing the unofficial version.
Could someone please help me with fixing this as I've been trying to for 3 weeks now.
Device: s6 edge g925f (vodafone uk) 6.0.1

The phone originally for vodafone uk and you flashed the latest firmware on it?. I think nothing can be done except restoring the imei from backup manually.

The phone was on version 6.0.1 and I flashed the same firmware versions. I deleted the backup of the original firmware unfortunately. So does this mean that nothing can be done to fix the phone?

Try reinitialize the phone using smart switch. Hopefully it could fix the broken imei. Flashing the correct firmware(odin/smart switch) sometimes helps to restore imei.

[Fixed] My SM-G955U Has No IMEI or Baseband

EDIT:
I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition.
So, here is a bit of a story I will try to keep short.
I went to Vietnam and bought a S8+ from there.
It was a US S8+ from Sprint.
I used it fine there but when I came back to states I tried to put my Verizon sim in and it doesn't work.
I don't get any signal. But I am able to see Baseband and IMEI.
So, I tried to use Odin and flash one of the SM-G955U1 Firmware.
Now, my phone is weird and out with no Baseband or IMEI.
So I try to flash back to firmware it was on.
Same thing.
Any ideas why my S8+ is like this?

If you can get into recovery, what info are in those details?

What happens if you restore from the OEM function?

Try downloading custom recovery and flashing a custom rom. You will lose samsung pay but you might have a working phone it's a chance I would take if it was me. Your baseband is messed up try just flashing your carrier baseband . These are just ideas good luck
Sent from my [device_name] using XDA-Developers Legacy app

If flashing a custom ROM will fix your phone then so will downloading latest official Samsung ROM and flashing via latest Odin .
The second option above would be the best to try unless you're happy to have a custom rom and lose Samsung pay and anything that relies on Knox being functional

Update on the post, I sent it into Samsung. I should hear word soon if they can fix it and how much if anything.

Jtag dead phone to life and rewrite IMEI
First of all my phone is the s8+ G955fd, but I am sure that the people that helped me can help most Samsung owners with bricked phones.
My phone ended up being stuck on the first boot screen, I couldn't get into recovery or download mode. I installed TWRP and after that I lost my IMEI numbers( dual sim), so I tried to reflash stock and thats when i became bricked. I searched someone to help and found reference to the Fonefunshop in England. I sent it there and they said that the eMMC chip was bad. I searched for someone who could write to it or put a new one on the motherboard . I found A2Z cellular in Ottawa Canada. They used jtag to restore it to stock and they told me that the Fonefunshop had not opened the phone which is necessary to use jtag as they claimed, so avoid them.
The phone was now back doing everything it should except the IMEI's were null like before. I gave them the original IMEI's and the phone is working like new.
If your Samsung is bricked these guys can probably fix it and it won't cost much to find out.

the SM-G955U has a locked bootloader, so people should not be telling you to flash a custom recovery or custom ROMs. there is only one way to get root on this phone, through the samfail exploit, and safestrap is the only working recovery. I don't believe it supports CDMA networks but I'm not 100% sure on that. I have this device and I'm only aware of GSM carriers using it.

Just an update on this issue. I still don't have a working Baseband or IMEI. Any clues?

I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition via ADB.

Hi. Can you detail how you fixed you phone please? What custom rom did you use and the steps you used please? I have the same phone with the same problem.
Thanks

Be very careful with doing that. It can cause the EFS (the partition that controls IMEI, Mac and a few other things) to be completely corrupted. Which will cause the device to be useless without fixing it.
Now a little heads up. As messing with the IMEI is illegal in many countries (the US being one of them) There are only 2 ways to fix an IMEI issue allowed on XDA.
1. Restore the backed up EFS partition
2. Return it to the OEM to be repaired.

What did you do after you deleted EFS? I can delete in Combination but I dont get the IMEI number back.

Please I need all XDA members assist ,because of I mistake delete EFS with combination file on my G955U VZW , I have null imei number, then I repair it by flash qcn with z3x Samsung tool , but still I have IMEI number but emergency call only is still display without service ,

Need help flashing rom on my Samsung device.

Hi everyone,
I bought a phone from a friend, turned out the phone was a Russian version but the was thing is that, it doesn't connect to my local network, sim works fine but whenever I try making a call, it says "not registered on network ". I Googled this issue and finally found a way which I hope will work. And that's flashing it with firmware made specifically for my region, but the model number differs. The phone model number is SM-A750FN while the firmware I found online for my country is SM-A750F. Can I flash it without facing any problem? Or if you any better way to solve the network issue I'd be glad to know.
Thanks in advance.

You don't necessarily need to flash the whole firmware, you could probably just extract the modem.img from the A750F firmware and then convert the modem.img to an Odin flashable .tar file and then flash the file using Odin. All you should need to change is the software that controls your radio.

Yes, IMEI changing will definitely cause an issue, the network will not recognize your device if the IMEI is different than the one that should be there. There is more than one tool or method to fix your IMEI issue, I'm not familiar with those tools or how to use them as I've never had a need to use them.
Try doing a Google search for:
"How to repair IMEI on (your specific model number)".

Thanks
