S8+ LDU - Samsung Galaxy S8 Questions and Answers

Hello guys,
im working for a german operator and we got the s8 and the s8+ ldu's
im wondering cause the normal s8 have no imei number on the backside of the device.
the s8+ got a IMEI number so it seems to have a gsm module inside.
i just flashed a stock s8+ rom but its not recognizing my simcard.
do i need to flash a new modem also?
any tips?
on the back it says LIVE DEMO NOT FOR SALE, but there's a IMEI number directly over it.
regards

Hi there. I have an LDU of the regular S8. But mine cant even get into demo mode. It's recovery or Download mode only. What stock firmware did you flash to make it at least work?
My model # on the back is SM-G950XU
I've flashed like 6 different stock FW, it passes in odin and then as its loading up it stops, then says "erasing" and goes back to saying "Security error: an unauthorized firmware has been flashed and the device is locked"

same Issue 950XU
Hi nashville did u fix ur phone because i am facing the same issue with 950XU

Hey there. Sorry for the delay. Yeah sorry I NEVER found any kind of workaround. I ended up selling the unit for $70 to someone who wanted it for parts. Nothing I tried worked!

If you guys still have the phone. Do not flash a newer ROM! You will never be able to go back to bootloader rev 1.
Find the XU firmware online and flash that.

some users report that it worked (i doubt since efs partition is not included in the firmware)
try it, nothing to lose.
I9500 sold in Qatar are coming from UAE (if not mistaken). to be sure connect to Kies and see what are the last (3 letters) under phone firmware. i think it is (XSG).

Check to see if you still have your imei or not... That's probably the reason, you lost your efs/imei...
If that's the case then if your made a efs backup like you should have,restore it. If not, try flashing stock.

Did you test your sim card and make sure it is ok? Try to out this sim card into another phone and make sure it works? Put another gud sim card into your Note 3 and check if the problem still persist?
Dial *#0011# and check for the RX, TX value? Can you post this screenshot here?

Anybody please
No Network neither
Hi everyone,
i got almost the same problem. My SM-N9005 was on the Standard TouchWiz Rom (4.3, rooted) when i updated to 4.4.2 via Kies and rooted it again.
Now my Phone shows me signal bars but tells me "Emergency calls only". I still have my IMIE.
I reflashed the stock ROM but that did not fix my problem sadly.
Hope you can help me!
UPDATE:
I reflashed the stock recovery once again and factory reset/wiped the data and now it somehow works again. Maybe that helps
UPDATE 2:
It seems like that was just working for a short moment, now after flashing the X-Note ROM (and Kernel) the "not registered in Network" message comes again though i got like 4 bars. The bars just are random somehow and jump up and down every few seconds.
Another Update:
While charging the phone (via PC or via the original Charger) i get a Message that it stopped charging because the battery temperature is too low. I Hope nothing went physically wrong?
your note 3 seems to be unlocked by SPT box or BST dongle
select wcdma/gsm or 3g/2g in mobile network and your network will connect
hope this helps:fingers-crossed:
Thanks for the reply, but my I bought my note 3 unlocked and new from my carrier and havent changed anything regarding the IMIE.
I was thinking about the modem beeing broke down while i updated to kitkat, and therefore flashing a new one. Any ideas on that?

If everything else fails try to write in Odin (or better yet in Mobile Odin Pro) just the modem - and aim for an older version, something like MI6 (present in MI7 firmware) or MJ1. With Mobile Odin Pro you MUST be on stock recovery and it will work perfectly first time, with normal Odin there are some reports that you might need to write it twice or something like that - search around.

Tried that, had the same problems with the MI6, and with the MJ1 it got stock when i tried to unlock it...I was on the Xnote ROM though, Ill once again will try flashing the stock rom...
did you try another sim card ?
Sadly, the sim card works in my Note 2 without any problems... I think its sth that got physically destroyed somehow. When i plug it into the charger is says "stopped charging battery too cold"

Firmware Cross-compatibility

was just wondering... since G900I and G900F have the same specs would it work if i flash the G900I firmware onto a G900F handset? just asking because i live in australia and i have the european handset G900F

im just a little worried if anything could go wrong. i mean i have backed up everything... EFS, nandroid backup etc.
So worst case scenario it just wont boot yeh? i can install a G900F stock rom back on through odin and everything will be ok?
You will never know mate. The worst case is your device will be bricked ? it all depends on your nerve mate. There are still chances you could restore your bricked phone to normal by using odin, make sure you have a back up of your stock rom
My advice is to use custom rom

only thing that is pissing me off is that I think my handset got shipped with a faulty gps module and now that my knox counter is 1 my warranty is void. so basically everything on my phone works except for gps
Sent from my SM-G900F using Tapatalk
That sucks. I feel for you bro. But just to make sure it is defective. Flash the original region of your phone brand to test before jumping to that unfortunate conclusion
I live in australia and I bought a g900f which I believe is for uk or europe. For australia its g900i and I cannot install the firmware onto g900f. But when I installed gps toolbox it didn't even give me anything. I can understand its one thing to take a long time to get a lock but not seeing any satellites at all is another thing. Ive tried around 10 different gps.conf files designed for australia satellites

Ok, you can do it.
I intended to test it myself first coz I wanted to flash G900F on my G900I in reverse.
Now it's impossible for me coz unfortunately I have been ended up with downloading corrupted firmware due to unreliable internet connection (5 times 2day so far)
If you're desparate to flash G900I, you MUST back up your current firmware PIT file. In case you fail to flash G900I firmware, that PIT file will be used along with your stock firmware to recover your phone to its pristine state.
To do it, please follow this guide , if you're using G900I 16Gb, you could download the PIT file from the OP immediately.
Hope it could help you, please let me know with your attempt. I'd like to help you out in case any thing goes wrong with your phone

ok, so here is the update. since installing G900I firmware failed through odin due to bootloader incompatibility i managed to install it through mobile odin. worked like a charm and even had the telstra bootanimation lol. wifi, bluetooth and everything seemed to be working fine. however my gps is still not working and the G900I seems to have the same gps.conf file as the euro version. i definately believe my gps module is either faulty or not connected to the board properly. is there any app that can tell if the gps module is even there or turned on as no one else is having this problem.

they said i couldnt anyway because i bought phone from kogan. they said i have to go through kogan.
i can't remember if gps was working before i rooted phone. couldn't have been because everyone else running alliance rom said they havent got problems with gps so it must be a fault unit. im going to take it to a phone repair shop and see if they can fix the gps module.

Can't get signal

Hi there,
So, suddenly, my Samsung Galaxy S4 (i9500) stopped getting signal.
It shows my gsm carrier, but do not get any signal.
When I tried to use RegionLock Away, it shows me this error:
"Could not locate csc data you could try flashing a csc package to correct this."
And when I try to make a call, it shows: Mobile network not available.
And solution for this?

No. I got Lollipop and than started to get the error.
I'm downloading one stock here, but I don't know if it is the right one. I got this phone from a friend.
After I flash stock, I'm gonna come here and edit this post.
Thank you dude, cuz I'm going crazy.
Where'd you get Lollipop, OTA, or did you flash it? It sounds like you probably flashed an incorrect modem.

I flash the one that the author post on the topic.
Well, I flashed the stock and now it doesnt even recognize my carrier and IMEI is null.
There is any way to find out where the phone came from so I could download the stock?
@edit
Just flash one stock rom called: GT-I9500 imei fix.
Show an IMEI that isnt mine, I'm able to see that I have voice mail, but can't get signal.
Anything?
Sorry for the up topic, but anyone?
You shouldn't ever be messing with anything involving IMEI repair unless you are sure that you need it, and you know exactly what you're doing.
If the problem appeared without you doing anything then you got an hardware failure.
Replace the emmc chip if it's an imei problem.
