I got a GNOTE from negri on 11/9. It seems it was s polish version. It has been working wonderfully on ATT (after adding in APN manually for 3g/H+ -- voice worked out of box).
I rebooted Today (11/13) and now it has the crossed out circle instead of bars and says "Insert sim" when I start to do cellular related activities.
I have Seated and reseated; nothing. pulled the sim and put back in my SGT (phone enabled) and it works. Put back in GNOTE, still no sim detected! Stuffed SIM in my N1; it works.
Any suggestions?
I had a similar SIM card issue when I tried to activate the 1700MHz band in Service mode (for fun). Wipes and stuff didn't solve anything. The way to revert it for me was flashing a full stock Samsung firmware in Odin.
Can you provide more details on how you did this?
Where does one get a full stock sammy note firmware?
Are there some good instructions on this?
I have flashed my SGT via odin several times. Same odin? Same process?
In the development section you will find some versions.
The key for me was flashing a new Modem (Radio/base band) image via Odin I think. I changed Kernels and ROM's but only flashing a ROM including the Modem got rid of my SIM issue. Not sure because in the end I flashed a full N7000OXAKJ1 firmware in Odin from here:
http://forum.xda-developers.com/showthread.php?t=1310513
It did the trick, though the tread is dead. I think any ROM including Modem might help, I currently running the 2.3.6 N7000ZSKK1 firmware and it is great, also included a Modem.

when this happened to me, also due to turning on 1700, I was able to reset my phone by doing a factory reset. Unless your modem.bin is corrupted, you should not have flash a new rom.
- frank.
ugh....
you mean factory reset via Settings->Privacy->Factory Reset?
Tried that... No affect. Is there another way to do this?
Was hoping to fix w/o the flash. NOTE: I did go into that service menu with the 3G Freq are listed. I was curious when I saw the post. But I never changed anything. Just saw the screen and thought "neato". I wonder if there is another service screen that has an option for 'unfuck'???
Still searching for answers, before trying the ROM route...

Factory reset and toggle band settings seems to have worked for him. I got frustrated and Odin flashed everything, that worked for me.
whoa....
when I try that procedure (* # * # 1 9 7 3 2 8 6 4 0 # * # * ) I get a pretty empty screen...can't do much of anything...just some useless buttons on the bottom of screen when I select the menu button...
I think I recall seeing another number for doing a similar thing...

OMG I have the EXACT same issue as you, and I got mine from NEGRI also! It was working perfectly until last night --- all of a sudden I got that circle and I've been trying to fix it since then! Please keep me posted if you find a solution, I was going to try and contact Negri tomorrow for an RMA.
still nothing.
I did a root. No changes...
I did a rom flash of kk1 ... no changes....
I was trying to reflash the modem with KJ6 modem....but have a signature failed problem...
now what???
I solved my issue by a combo of those steps.
I did full flash in Odin of jk1. When I rebooted that didn't solve things so I wanted to flash the other recommendation, kk the Chinese rom.
Upon entering recovery I noticed I lost 2e and was on 3e. So I had to download chainfire's rooted jk1 kernel and do that zerg rush to get root. It was while I was doing that that suddenly my similar got recognized. By the time it finished installing the rooter kernel I had full reception again. I flashed kk just for good measure and its been smooth since. Hope it works for you too and I'd love to know what the heck broke it in the first place??

hi fwelland, it's hk1981...so you tried the rom flash and it didn't work?
Hi hk1981,
No the KK1 rom flashed fine. By all accounts it works well, except that pesky phone part. This KK1 rom is really 'clean' and very little bloat-ware and it installs a vanilla boot animation (not a carrier one). All that is nice, but didn't help my problem
I did notice a peculiar thing: while in recovery (android recovery, not cwm) I get some warning about "CSC something or other, fixing".
I have a short list of things to try before I have exhausted my DIY options -- the post just above looks promising.
I think the answer is out there. We just need to keep looking and keep attention on this thread and others like it. This place and others like it are a huge help and I'd like to solve it and then give back a good set of instructions.
FWIW: I wonder if there was some voodoo in the polish rom that caused some issues in the modem when a different than expected sim was installed? Or if one of those funky polish apps that updated it self before I could turn off auto-updates has something to do with it (doubt this -- I don't think apps can do stuff unless rooted...)...
Still searching....I got this other pesky problem to deal with now: w-o-r-k

I had that problem too, it doesn't detect that CSC and then goes ahead and applies something. Check to see if you are in 3e recovery, I think you are after having flashed vanilla JK1.
Re-flash Chainfire's rooted kernal for your appropriate version and then go back into recovery and it should be 3e and you can flash thru CWM then.
Also note; each time I flashed, I also wiped data/cache/davlik just to be sure.
yes it does say:
Code:
Android system recover (3e).
So I will need to try the methods you (crippenx) suggested.
FWIW, the CSC message that I get when I first enter recovery is:
Code:
# MANUAL MODE #
--Updating application...
Successfully update application.
--Appling Multi-CSC...
Installing Multi-CSC
Applied the CSC-code 'TGY'
Sucessfully applied multi-CSC.
I have no idea what this means. It does it every time I enter recovery.
FWIW, I never flashed this gnote with ODIN (I have used ODIN on my SGT several times). I got to KK1 by first rooting via http://forum.xda-developers.com/showthread.php?t=1329360 (using 'forget the above steps') and then using the CWM 'kk1-wipe.zip' from here http://forum.xda-developers.com/showthread.php?t=1342797 -- I didn't use ODIN to get to kk1.
I see on the Root/Unroot thread, there is a KK1 kernel option for 'simple'. I think I will try that with rooted already script.
But I am open to any/all suggestions...

My rough guess is that the phone has a list of 'valid service menu options', and it cross references it with what is on the SIM card.
Once the phone decides it's not going to read your sim card, the service menu is blank. This is a real headache.
That's why once I set the 1700+2100 combo, and my phone boycotted my sim, I wasn't able to set it back.
That's really dumb, imho, to have a one way toggle like that. I'm fine for settings to enable/disable other settings, but for a setting to disable itself? ugh.
I would really like to know what's going on. I was planning on switching to AT&T before my next trip (which is soon) but I can't risk my phone glitching out like that during the trip.
Actually, the ROM is on my SD card so I guess it wouldn't be THAT horrible, but it's certainly not something I want to do. Perhaps we just need a way to flash back the modem.bin, assuming it's corrupted.

Sorry typo on my part. You are in 3e recovery because of that base flash, now you need 2e recovery which you can get via chainfire's rooted kernel. His installation procedure runs a batch file that uses that zerg rush exploit which I gather is partially from gingerbreak. It was during this procedure that my baseband suddenly came back, my sim card finally detected.
Once that was done, I entered 2e cwm with volume up,power,middle button and did erase of data,cache,davlik and then flashed kk rom via zip file.

For me flashing all partitions via Odin worked (no pit file or repartition). Tried all sort of stuff from recovery first with no result.
I don't know what partition flash from Odin did the trick, but you could try Odin flashing a Modem separately and check if that works. If not try the rest?
Finally got back to this.
After much fusing I finally got KK1 and cwm working. It was odd, I had to re-run the whole root process again.
At that point I could apply the KJ6 modem w/o any problems (via cwm)
no dice!
Still dead!
Not sure where to go next???
Can some one provide a few details about flashing a modem,rom and/or kernel via ODIN? Perhaps that method will work....

Oh when you flashed jk1 I assumed you did it the old way via Odin and the multiple files. That's how I did it and you're right, that may be what fixed it as when I used to brick my sgs and sgs2, it was always a full Odin flash of stock that brought it back from the dead
To flash in Odin put your phone in download mode. Fire up Odin. In csc point to csc file. In phone section point to modem and for PDA you point to the code file. Don't put anything for pit or bootloader and unchecked the repartition toggle.
Connect your phone and wait for Odin to detect it and show yellow in the status window. Press start and you're good to go. Hope this does it!

Hi,
I am trying to fix a broken SM-T710 which is stuck in a boot loop. I have been working on this for the last 24 hours and I have not gotten very far. I would be very grateful if someone could tell me what else I can try.
First, here are the symptoms:
Holding the power button while the tablet is not plugged in will cause it to show Samsung Galaxy Tab S2 powered by android, then it shuts off.
Plugging in the tablet starts a bootloop, flashing the same message as above, shutting off, and repeating
I have not been able to get the tablet into recovery mode
I can get the tablet into download mode (home+vol down+power)
In download mode it says:
ODIN MODE
DOWNLOAD SPEED: FAST
PRODUCT NAME: SM-T710
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Custom
Secure Download : Enabled
KNOX WARRANTY VOID: 1
RP SWREV: B:2 K:0 S:0
What I have tried so far is connecting the tablet into my PC and running Samsung Smart Switch. I did the emergency recovery and initialization within that software. After entering the model and serial numbers, it downloaded the software update and initialized it on the tablet, I could see the progress bar on the tablet during the initialization phase. It successfully resets the tablet but then the boot loop begins again.
I also tried downloading the firmware from Sammobile and flash in Odin. The file I have tried flashing is T710XXU2BPB1_T710XAR2BPB1_HOME.tar.md5. ODIN flashes the files and resets the tablet...back into a boot loop. I have not tried checking re-partition when I do this, as I do not know what to do about the PIT file
Is there anything else I should be trying? Thanks
Just flash using your original firmware.
This tablet came from eBay so I do not have any idea what the original firmware is. Everything I know about the tablet is in the first post. I assume that Samsung Smart Switch downloaded the original firmware since it required the model # and serial #. I am guessing that the tablet is from the USA but I do not even know that 100%

It's a hardware failure. Several others have had the same issue. Main board needed to be replaced.
I have the same issue here. It's a T715C which I bought in Singapore (distress purchase, rather than bargain hunting) and brought back to the UK.
Given that it's more than a year old, but a known fault, does anyone have any alternatives to taking it to the local recycling centre?

Try NAND erase while installing the firmware with odin.
I'd also try installing kitkat firmware if you can find it. Sometimes a downgrade fixes issues. You can then upgrade as normal.
Thanks. I'll have a Google and work out what that means. All my (many) Android devices have always been unrooted and only upgraded OTA!

Hang on I had a bit of a brain freeze there. The earliest firmware will be Lollipop.
Try the Hong Kong firmware. Instructions to install are on the page.
https://updato.com/firmware-archive-select-model?record=E4B33EF21DCD11E6949E0CC47A44B7B2
Worth a try, I guess. Used Odin to flash the oldest Lollipop firmware I could find - with the NAND Erase All option - and it all seemed to work, but came back in the same state - six seconds of the boot splash screen followed by a second of black screen and repeat...
(Tried Marshmallow ROMS, too - no luck)
Ok try and do this as best as I can......
I bought a vwz S8 G950U used off someone from offer up was working fine when I bought it so when I got home I factory reseted to get all the users apps games etc off it and then it asked for a Google log in info (which I don't know) and I tryed to email the person but won't respond
So I tryed to install factory to binary to bypass it from what I been reading says I can do well I can get in factory binary now but now I cannot install oem stock firmware which I have downloaded 7.0 (what was on it ) says factory binary samsmobile and xda but every time odin3 gives me a fail message I have tryed odin3 3.127,3.13.1,3.12.3 and I think 1 more but every time I get a error....
So right now when I turn on the it his to factory binary mode and don't know of this helps but the battery won't charge past 80%....
What I'm asking if someone can be kind enough to help me out with this issue
P.S. I also tryed to instill Oreo 8.0 also but failed as well....
I can get any I go and post pics if that helps as well
Thank you in advance Jason A.KA. PpperoniRedd

Phone Problem: Boots to the very first screen with the phone model and then turns off itself, vibrates, and relaunches..... (repeat repeat). It did use to reach the Samsung screen before my (what I thought was) successful FW flash!
Hey, so im having a mare trying to flash some firmware on my friends Note 8 using Odin3 and pretty much guessing at firmware to fix this phone. I downloaded the latest version that seems to be available.
The phone Model number is not known exactly but its a single sim, UK spec (Carrier: 02) so am assuming it is the SM-N950F
Im slowly downloading fw files to try and get this phone to reboot - but no such luck! is there anyone with enough patience to try and help me install the "correct" firmwares?
I tried with my first attempt and it fails in odin with a message: SW Check boot loader 14 binary 13 (or something along those lines - which I tried a search for here in the forums and was something to do with the compatibility of the bl and fw not being correct)
My second attempt was a success through Odin (Cleared and Pass!) but now it only gets to the very first screen and reboot loops straight away without getting to the Samsung screen.... so not really a success my end!
Can anyone help a Android noob?
Not looking to keep any data what so ever Just want a full factory reset.
Phone last worked properly on 23/24th December last year and my friend hasn't bothered with it since when it bricked.

Hey bro I am not a pro either at this but doing this since quite a time now,
Your first attempt failed because you tried to install an older version of android whereas your device had a newer version installed previously....SAMSUCK does not allows you to downgrade your android model...
Your second attempt resulted in a bootloop , I will suggest you to reboot the phone into recovery and format it once, it might work.....

It should boot after flashing that, it could be a hardware problem preventing a successful boot :-( Probably worth trying different filmware though, you could try BTU (UK) or XEU (UK & Ireland)
Bro i will advice you to just get over this stock rom and install some custom rom.
You can install a custom recovery like twrp through odin and then using that recovery install some custom rom made for your device.
All these you might find in your device's xda forum.
Brp i just checked and found that galaxy note 8 has plethora of custom roms available just install the one which you like.
You can see the installation process on youtube.
Samsung Tab S8+ won't update via wifi, I get a server error message when I try, last worked in June and since then it hasn't worked. Tried clearing cache, restarting and everything else I can think of. Contact Samsung, I'm just saying phew... not much help there. Anyone have a solution to the problem?
My Samsung Tab S7+ 5G is working fine on wifi, no problems at all.
Hi. To be 100% clear, you don't have the bootloader unlocked, and you're not rooted, correct? (Although I wouldn't necessarily expect the problem you're facing with both of those things)
Bootloader locked, no root, just like straight out of the box.
What CSC (Country Specific Code) is your Tab S8+? Quoting another user on here - I don't remember who:
Go to settings > about > software information > service provider SW ver
The region code (CSC) will be written there.

And what specific model number?
I don't really have any specific suggestion other than a factory reset, which I know is extreme, and wouldn't guarantee to fix the issue. You could always use the SamFirm or Frija Windows programs to manually download the firmware, and use Odin to flash it. As long as it's the completely stock Samsung firmware of any type for this device, it will work without unlocking the bootloader.
