[HELP] (SOLVED)Problom Regarding Updation of J7PRIME - Samsung Galaxy J7 Prime / J7 On NXT (Exynos7870)

Hi all. I never posted anything here. This is my new post. I don't know whether I can post here or not. Please allow me to post here the moderator.
I'm doing this because I don't have another way. :crying:
The problem is I tried to revert back to stock android, first time I got Odin flashing error. So I searched and found a solution. So In that way I done. But it shows "use emergency recovery mode in smartswitch" so I tried that also. But in smartswitch the firmware is not showing.:crying: It says check the S/N and Model No. I tried so many times.
At last I found a way that, when I face the error I flashed stock recovery and reset the phone and it turned on. I was very happy. But in other side it shows as On NXT. IDK what to do. And device status still Custom, although I've done it through Odin. :crying::crying::crying:
This is the main problom that I'm facing. If it familier to anyone of you, please help me. I'm in this problom since 3 weeks. If anyone can help me it will be really great for me.
Bcz of that I flashed a custom rom. Now I'm on it.
IF ANYONE CAN HELP ME PLEASE REPLY.

Kabooot - it looks like your /efs folder is corrupt. If you have made a backup of that folder, you can try restoring it. There are some pointers on this thread.

If following all that stuff from the link does not work (I hope it does!), then you might try to flash a firmware with Odin, and select the option "Phone EFS Clear".
NOTE: I am not entirely sure this is safe!
But when I had the EXACT same problem you are having, I reflashed my phone like 20 times with many different firmwares, and a few times I selected that option. Then one time... just randomly... my phone started working, and I even got back my original IMEI and stuff.

I think he is a young kid & may not have a lot of experience/patience of many of us here, I think some patient soul here can guide him to flash an official ROM over Kies. I think Kies can see the phone in download mode & can update the firmware.
Have you solved your problem yet?

I Hope You NEVER Face This...

I searched the net and saw lots of suggestions which lead to Dead-End.
I'm facing with a Galaxy S containing UNKNOWN BASEBAND & NULL IMEI.
-- I Flashed lots of firmwares(Including Custom,Official-->Froyo-Gingerbread) and modems(Including froyo,gingerbread and ICS).
-- I don't have ASANSAM Dongle.
-- I have Z3X.
Any Suggestions will be greatly appreciated.
THX in advance.
Wow, lots of answers
I'm surprised with these suggestions,
thanks guys.
I have not ran into this problem myself, and therefore haven't extensively researched it, but in another post I just read someone noted that losing your IMEI sometimes happens when flashing to ICS—and he also said that, if you did not backup your EFS folder, the only way to get it back is by flashing back to Gingerbread.
I am completely oblivious to the validity of what he said, but it's worth mentioning if you're out of ideas. If anything else, it can help you Google a solution.
Here is the original post. Good luck!

you do not state what you did to end up with this suitation. ie when it first occured and if you have done anything after this.
you PM'd me for assistance but you do not have PM enabled on your profile.
More details please and enable PM on your profile if you are going to PM me again.
Hi,
I had the same problem. Absolutly no data from gsm or wifi after a new rom install. I had 2.3.6 installed, i flashed for slim ics 3.2 after rebooting, no baseband. I just download a baseband (you can find it on xda) and flashed it in recovery mode. All is fine now and it took 3 minutes.
Hope it will help.

Tried updating to ICS through KIES. Update failed

Hello guys.
I really need some help. Im going away for 2 weeks on 4 June. And after i come back ill be ghone after 2 days again for 2 weeks and i need my phone!
My story:
I saw an update for my phone to ICS. So i plugged on my laptop and put the update on with KIES 2.1.3.
At about 64% the update didnt go ferther and it gave an error report.
The program KIES shut down, and my phone turned off.
I putted everything back on. But now my phone says this:
''Firmware upgrade encountered an issue. Please select recovery mode in KIES & try again.''
KIES doesnt see my phone anymore. And the recovery mode i found on the internet.
Volume button up, home button+ power button doesnt work.
It keeps going to this screen.
My phone was 2.3.6 standard, non rooted etc etc.
How can i fix this fast?
I tried rooting and flashing, but i just cant do anything with my phone exept this screen i explained.
Thanks in advance.

Just download ODIN app for Windows, get right stock firmware from development thread ( Dr. Ketan's post ) and flash it with ODIN. It's as simple as clicking select file and start. Everything is described in the thread with firmware downloads.
Yes. Then there is hope. Now I recommend you to try flashing one of the stock roms from dr.ketans thread in development section.
Its not very complicated. But feel free to ask if you need more help.
I just cant explain how happy i am with this forum.
Brings so much luck into live
Thanks.
Ill see if i need more help. Hopefully not.
Is there any dutch ICS rom?
Or should i stick with a basic english?
I got exactly the same problem. Called T-Mobile's helpdesk. With everything I asked, the girl said, it's in the manual. Finally, the best she had to offer was for me to send my Note to Samsung.
So then I started looking for a solution myself and found it here.
Solved it with the said solution. Flashing with Odin is a piece of cake. Thanks for the expertise folks.
Good thing we can help. Wouldnt call myself an expert though

Well i searched for hours to. My sister had her S2 upgraded with KIES. That worked, but the ICS update itself was plain suck.
I fixed it thanks to XDA forum. Nothing found on the internet exept sending to help desk.
Same with what i got now.
But now it is fixed and im thankfull to the ones helping.
Now i am willing to try ICS without KIES.
Lol in kies you have recovery mode you missed an option

BTW, after getting my Note up and running again, I used KIES again for updating to ICS and this time I had no problem at all.

For me this didnt work. KIES had an upgrade, but seems like it still doesnt do the job right.
Ran some tests. Now i am back at the issue.
Now Odin doesnt want to continue updating like KIES always does.
I wish i didnt do the tests...

Now ODIN is stuck at syaing ''BOOT'' above ID:COM.
How can i fix this?
Well seems like the Dutch roms aint working.
I did an European right now wich worked.

[SOLVED] Problem Sim Card: No calls, no sms & no 3g

UPDATE
PROBLEM SOLVED:
Go to this thread for the solution.
http://forum.xda-developers.com/showthread.php?t=2548453
Hi all,
Since yesterday I've been trying to fix my phone.
It doesn't recognize my SIM card anymore.
I think it's my fault and I'll have to go to the Samsung store but I thought someone here might know a solution.
I'm aware that I did something stupid...
So here's the story:
Yesterday I flashed Cyanogenmod 10.1, I installed some apps and I noticed that already 4GB of the 7,42GB was used.
The apps only took 2 GB of the 4GB. So I went to the CWM recovery, scrolled down to mounts and storage and removed all the storage...
Then I flashed Cyanogenmod again (because everything was removed, OS included). And now my SIM card isn't working in my device anymore.
It's for sure that my SIM card isn't the problem, because when I put my SIM card in my old phone, it will work.
After flashing I got a message of Vodafone, which says that they will send the right settings for my phone to use their network.
But that message never arrived at my phone.. I also tried to manually set up the right ''settings'', but that didn't work.
I have tried anything I could. I thought maybe it will work if I install stock rom, but again, it didn't work for me.
I still think it's a software problem, but it might also be a hardware problem.
It might be useful for you to know that I live in Holland. (maybe things are working different here, idk)...
try this
try this ....
using root explorer or file explorer or what else,
open file "factorymode" in efs/factoryApp directory, it probabely says "off", change to "on" (yes "on" is the correct setting to turn it off), then save
reboot
good luck

You still got your IMEI?
If official wirmware won't work, then try this one first, and then flash your official firmware.

Unluckily for me it was already turned ON. (so this isn't the solution).

OK, I'll try this. Thank you for your reply!
I'll come with edit if it was successful or not.
About the IMEI, Yes I have it.
Should I do something with it?
UPDATE (I tried the 1st method):
I went to the thread you linked to called ''[HOW-TO] Enable Three Button Combo [RECOVERY]''.
I don't know exactly what it does.
It enables the ''Three Button Combo'', but I thought I already had this.
I did ''Benzonat0r's way'':
1) I flashed it as PDA
2) After flashing my phone rebooted
3) Nothing changed, still no working calls, sms etc.
Now I think you meant the 2nd method.
Should I do the 2nd method, so I'll get ''a "La'Fleur" branded phone''. ?
Is it safe to flash this Russian ROM?
"I8190 серв. укр.rar" is now downloading.
I'll try this now.. Hopefully it will work.
UPDATE:
I have tried the 2nd method now.
I flashed "I8190 серв. укр.rar". (PIT, PDA and CSC).
After that it didn't boot (which is right, because it's ''La Fleur''.)
So I flashed official firmware (dutch).
After my phone rebooted, I could see immediately that it didn't work
It doesn't show the signal.. and it doesn't have signal.
I'm sure that in my region the signal of Vodafone is OK, because when I put my SIM card in my old phone it works..
I'm sure my SIM Card is fine, it must the software of my phone..
It's my fault, I shouldn't have formatted all in ''mounts and storage'' about 4 days ago...
Another isue is the language which was displayed was Russian...
Normally after I flashed official firmware the language was dutch.
What I'm going to do now is again format all in CWM recovery.
If that doesn't work for me, I'll bring my phone to the Samsung store if no other solutions found..
Anyway, thanks for your help.
If you have any other ideas please tell me.
Thanks in advance!
Greetz, Daniel.
Problem Solved 100%.
Solution: http://forum.xda-developers.com/showthread.php?t=2548453
The instructions written down below in this thread and post did NOT work!
I solved the problem myself:
I formatted again everything on my phone. (in cwm recovery at 'mounts and storage'.
I flashed stock recovery.
I flashed official firmware.
Done.
No more Russian language issue.
This thread can be closed.
The solution was a lot easier than I thought.
I think a ROM bugged my phone after I formatted all.
So as I said, problem solved.
Thank you for the your replies!

Rooted one plus 3t with corrupted recovery stuck on bootloader

Hello everyone. First of all, sorry for the long post.
I just bought a OnePlus 3t three days back. Updated it to oxygen 4.1.3 and then rooted it as well. Everything was working fine. But then I decided to downgrade to 3.5.4 since I wanted to try out Xposed Framework. So I downloaded the OS from OP Support website, and went to twrp recovery and installed the os 3.5.4 from the internal memory of the phone. It seemed to install properly but when I rebooted the phone, it started asking for a password. I tried every possible combinations of my passwords but to no avail. I saw online and found some video where I was supposed to flash a new recovery which I did. After that the phone got stuck in Bootloader. There is no bootloader and recovery version detail available on this screen.
If I try to restart the phone it gives me the following error, "Decryption Unsuccessful - Your phone storage has been damaged, unable to read data stored in your phone! To continue to use the phone, you need to reset the phone." There's a button at the bottom of the screen to Reset Phone. When I click that the phone goes back to bootloader mode.
Please help me out here. I have no clue what to do right now. I have tried flashing several recoveries but they give an error "cannot determine the image filename for abcd.img"
Any and all suggestions are welcome. Thanks in anticipation.

Thank you for the reply. I haven't yet tried it, since the computer recognises the phone just fine. It even shows up in the fastboot devices list in cmd. Maybe, I should give it a go.

Ok so I did manage to reinstall twrp. But I have no idea what to do next. Any suggestions ?
I managed to fix it. After the twrp recovery was installed, it started asking me for a password. Which I tried and didn't work. But then I just wiped the phone and it went back to factory settings somehow.
Now the phone is back to oxygen 3.5.4 and works fine.
Hope this can be helpful to someone else.
I'm glad u fixed it
Can u please post the correct steps to avoid this issue in the first place .
I'm on 3.5.4 but I may want to try latest versions and come back to 3.5.4
