[Q] HELP! Samsung Galaxy TAB not detecting SIM - Galaxy Tab Q&A, Help & Troubleshooting

I wonder if anyone had problems with their Samsung Galaxy Tab after Gingerbread update via Kies? I updated mine yesterday and today my TAB auto shut down a few times and can't start up property. It auto reboot a few times before it boots up normally. Problem resolved after factory reset, but my TAB can't detect my sim card anymore. It states 'No Service'. Darn...
I even have problem trying to connect to Kies.
For your info,
PDA: P1000DXJPE
PHONE: Unknown
CSC: P1000OLBJPE
I think maybe the ROM for the phone is not installed correctly? How can I fix that?

You are correct, your tab is missing the modem. To giveyou advice, you need to say your model, carrier, and region.
Do you have odin3 software experience?

My Galaxy TAB model is GT-P1000 (not sim locked), sim card and region from Maxis Malaysia. I had just updated the ROM via Kies from Froyo 2.2 to Gingerbread 2.3.3 when this happens.
I just started rooting my tab few days ago by following some instructions on how to use Odin and no.. I am not experienced in using Odin.
Thanks in advance.

P1000DXJPE_Modem
above file is P1000DXJPE modem flashable via odin.
1. Power off your tab and set to download mode (Power + Volume Down).
2. Connect you tab to your pc and run Odin.
3. Click on the [PHONE] button and browse and select P1000DXJPE_Modem.tar file.
it will look something like this.

4. hit start and wait for it to finish.
it will look something like this.

It doesn't seem to work. I followed your instructions and the phone software is still Unknown. By the way, do you think I should reflash my Galaxy TAB again? Any idea where I can download the complete ROMs for P1000DXJPE Gingerbread 2.3.3?

i think you should.. you could download P1000DXJPE on samfirmware.. hope everything goes well.

By the way, do I need the pit file, modem and csc for the flashing?

You will need the pit file. The P1000DXJPE update comes in 1 tar file.

I guess there might be some problem with my TAB. After reflashing, the modem software are shown correctly, but it is still not able to register to the network and one very strange behavior is, the device is not very stable. At times when I remove the sim, the device try to start up a couple of times before able to successfully boot, and at times the phone modem still show Unknown (very random).
The conclusion is, it is still no working no matter if the phone software shows unknown or otherwise.

Have you try insert your sim card to others phone?
I face the same problem once with my Htc HD2. Unable to detect my simcard.
Once I try to use my simcard on other phone, the same problem happen.
Meaning my sim card is broken. I go to the center and change with new simcard.
I do ask the customer service how can my sim card broken?, they said its unknow ;P.
BUT my suspect, is due to me always like to change my phone, with the same sim card..haha..at the end sim card broken!!

You tab will boot if your take out your simcard during the tab in ON condition. Its same condition if your sim card started to fail or broken, it will also reboot since its consider there is no sim card. Its normal condition with all smartphone/tablet.

Although I bought a WiFi + 3G TAB, most of the time the TAB is running on WiFi without sim card. But once a while I might use it with my sim.
My sim seems to be working fine on my Sony Ericsson X1 and I've actually swap two different sims to the TAB and both are showing similar results.
As I know before the Gingerbread upgrade on Kies, there will be an additional icon (sim card icon) if the sim is not inserted. As for my case now, the icon is not shown with the phone software = unknown. Sometimes after a few reboot, the icon reappear and the phone software is shown correctly but still unable to register to the network (although the 'EasyAccess' services on the Maxis sim is shown in the TAB programs).
When I tried another sim and if the phone software is detected, at times the coverage bar will be shown for a few seconds (registering) and goes back to the (/) sign again and attempt a few more times before the phone reboots itself for a couple of times.
I doubt it is a problem with the sim, more towards the TAB, either on the software or the sim slot hardware.
I wonder if anyone else had the same problem or if I am the only ONE...

i think you problem is more on the hardware side bro, if you are under warranty i suggest you visit a samsung service center.
* just don't forget to unroot and remove apps that need root before sending your tab for repair...

But you have the error about the network, and that usually means your access point name is incorrect or not there.

Hello!
I hope I am in the right thread.
My friend asked me to help her out with her tablet.
A Samsung Galaxy Tab p1000 Openline running CyanogenMod stable 9.1.0
Location Philippines
I tried to update the tablet but it is still not detecting the simcard
Do I have to download Odin ?
I want mobile data to work again for the tablet.
Thank you advance for any advice

Any ROM over 2.2 (froyo) wont detect SIM?

Im fine using 2.1 eclair and i get the standard NO SIM icon in notification bar when theres no sim and then when i insert sim i get signal as usual. However whenever i flash a ROM that updates android to 2.2 above (also tested 2.3) instead of getting the NO SIM icon i just get a NO SIGNAL cirlce with line through side, even when sim is inserted.
I am not on AT&T, the phone is unlocked to work in my country. The frequency my network operates at is 850/2100 but that shouldnt matter, it should still say NO SIM instead of NO SIGNAL.
Any help?
Thanks
What roms are you flashing? Not to sure about what to do in your situation but flash a i9000 rom like Apex and try that. What's good in the i9000 roms is you can modify the bands using *#2263# That might help your situation.

i used the roms here http://forum.xda-developers.com/showthread.php?t=1300843 and also a couple other, but only 2.1 will let me use the network. There hasnt been any other people having troubles with those roms so im a bit confused.
Do you have a link to that rom? Is there any major bugs with it?
Thanks for the reply
i flashed apex correctly but still have the no signal problem. anyone else have suggestions?
Maybe theres system files that dont get changed by roms that are only configured to work with 2.1? I have no clue :/
i went to the phone service menu (#*#*4636*#*#) and a few things i want to mention are...
Signal strength: 0 dBm 0 asu
GSM servie: emergency calls only
GPRS service: disconnected
Network type: Unknown
GSM disconnects:

There is a thing down the bottom called "set preferred network type". its currently at unknown, but there is the option of WCDMA (my network). How do i change to WCDMA, everytime i select something, as soon as i close the service menu it resets to unknown.
There is also a field called SMSC with an empty value.
I hope this info helps, surely someone can help me!
I really am no expert on this but if I were you this is what I would do.
I would start by taking my phone and doing a backup of my apps/contacts/ whatever else I had to have including the system files you need. Do this with Titanium Backup. Back this backup up on your PC or on your external SD. Then I would flash back to 2.1 eclair using odin. After that, I would master clear my phone using odin one click. This should reset your phone as if it were brand new out of the box. After that I would go through the whole root/flash rom process as if I were doing it for the first time. If it still doesnt work then you probably have an issue with that phone and I would try to return it.
Or you can wait for someone with more knowledge and time to troubleshoot this.
Ok, i just did the following and the problem is persisting.
- Flash rom back to stock 2.1
- Master clear
- Flash to 2.3.5
- Flash 2.3.5 kernal
problem still there. I see well over 140 views on this, could someone please look above at what im doing and advise me if i need to change something.
thanks
Did you take the sim and sd card (if u have one) out before flashing with odin?

Yes both were out for the flashing process and we're only inserted once phone fully booted.
you are rebooting once inserting the sim right?
might want to select the 850 band only...
It's not a good idea to remove/insert Sim with phone powered on. It can damage the card.

Yes I am rebooting. How would i go about selecting that band? The every single service menu i've tried have all the bands deleted. I.e there's nothing there.

Once the phone is fully booted I power down, take battery out and insert sim, once powered on the phone doesn't even try to detect it. If i go into mobile networks in settings it says no sim inserted. :/

contact the maker of those one clicks, the CSC may not have flashed correctly.or try someone elses gingerbread flash.
i have been JUST talking with the author of the THREAD you linked to, i am creating all one-click packages for rogers ATM
EDIT:======================================
you ARNT att..... thats your problem. those one clicks WILL flash ATT Carrier information, you need a multi CSC..... contact oneclick maker. or use NON odin flashes that dont contain CSC.
Im 80% sure im on the right track for your problem.
but why are you flashing ATT stocks if you arent ATT? those arent custom "ROMs" those are stock factory flashes for un-screwing up your phone.

I have flashed two roms since my last post. One is a simple custom rom flashed via Clockwork recovery, and the other just a PDA (no csc) via odin. Both of which do not fix the problem :/
If it helps i can provide images of the problem?
i still have the problem and 2.1 is very irritating. Does ANYONE have a clue as to whats causing this?

Here are images as promised:
All images are of the phone with the sim card inserted except for the 3rd image which states there is no sim card inserted.

2.1 with sim card

2.3.5 WITH sim card
2.1 service menu (*#2263#)
2.3.5 service menu (*#2263#)
2.1 messaging options
2.3.5 messaging options are same as above but without messaging center
2.1 recovery menu
2.3.5 recovery menu - didnt get picture, but is standard CWM menu
2.1 about phone
2.3.5 about phone
2.1 APN settings
2.3.5 when trying to access APN settings
So some things to point out are:
1. 2.3.5 does not recognize i have inserted the sim card
2. 2.1 recognizes the sim card
All other problems are linked around those two points. Hope that helps, and hopefully someone can help me resolve this!

[Q] No service ever

Im trying to get my original Samsung Galaxy S to work with my mothers SIM card (Vodafone, same network i was on when i used the phone), but im never getting any service whatsoever, the phone just isnt reading the SIM card at all. Ive attached a picture of the phone, so you can see what i mean, HERE IS THE IMAGE.
Ive flashed a stock firmware (was on cyanogenmod when i was using the phone) and deleted all data and reset to factory but cant get the SIM card to work in the phone. When i put the SIM card back in my mothers phone, it works fine
I would try putting my old SIM card back in, but since i upgraded to SGS3, i moved my number to a micro SIM, so the old SIM card I have, no longer works.
Can someone please suggest how I can get service on this phone?
Check the apn settings with your provider would be a good start point
Sent from my GT-I9000 using xda premium
Thanks for the advice. I dont know what apn settings are, so what would I ask Vodafone to check for me?
Yeah, phone them up and they will talk you through checking and a setting them, or they will have them on their website
Sent from my GT-I9000 using xda premium
All they said was that the sim card isnt compatible with modern phones as its a few years old :/
They sent me a new sim card which doesn't work. I rang harm back and they said go into a store. I did and they just gave me a new sum which still doesn't work....
I can't understand because he handset was the one I originally got from vodafone, and he sim I'm trying is also vodafone!!

Just wondering, is the sim card inserted correctly? , the cut edge must be visible
second, check your about phone, to see, you have a base band, and also IMEI by *#06# on your dialer , also install anetwork booster.apk from market using your WIFI
IF all is well, just put the phone on flight mode and reboot the phone, once rebooted, OFF the flight mode and check your network

The sim card is definitely inserted correctly
Sorry for my ignorance but what is a base band? I have factory reset with all wipes and then flashed the most recent firmware for the phone (can't remember what it is as I'm not near phone)
What does the app do? When I put it on flight mode I can't take out off flight mode.
Sent from my GT-I9300 using xda app-developers app
just got home and tried the IMEI with *#06# and it comes up blank - a dialogue box apears with IMEI as the title, but no actual number for some reason?
the Baseband is unknown in my settings, the firmware is 2.3.6 and build number is XWJVZ
didnt install a signal booster, as i had signal when i used my sim card and the phone is in the same house so it should still get signal.

Baseband gives the details of modem/Radio in use, if its unknown, than you have an EFS problem, thats why you have no network
to check menu>settings> about phone> you will get all the details and if you touch status you will get details of your phone number and network you are connected to.
Network boosters, increase the reception of signals, in the event your cell reception is low, but since you have NO service, its pretty much useless.
in gingerbread, you use your power button to On and OFF your Flight mode.
How did you lose your baseband, did you Flash something before your service went dead ?
anyway, suggest you download the i9000 Rescue kit from My Android Collections link below, to try a get your EFS back, to know more about EFS, please Read this http://forum.xda-developers.com/showpost.php?p=26827676&postcount=4512"
Yeah i used to flash a lot when i had the phone, but it always worked when i had it. NEver had any problems.
Yeah i know how to put it into areoplane mode, just most of the time i CANT take it back out. restart my phone and I still cant so i have to flash new firmware to get it out of aeroplane mode.
Im on downloading you SGS_Rescue_kit-13-1-2012.rar now. Could I just download some new firmware, hoping it has CSC, Modem and PDA instead of just PDA and then it will work? Im gonna try and sort this out once and for all
How do I use the rescue kit? flash via CWM? cant select anything to flash in ODIN
managed to fix it by flashing froyo then swapping to gingerbread. thanks for all your help

[Q] Baseband problems on Z3C

Hi there,
I have some serious baseband problems. Don't know if it's bootloader unlock related, because this was the first thing I did with my telephone.
I tried to relock my bootloader, but the problems don't go away. My phone originally ran on a Greece unbranded firmware. My network operator is Vodafone NL. I run version 23.0.1. A.5.77.
Once my connection is unstable, my Z3C sometimes 'forgets' the baseband settings and sets the network type to 'unknown'. I lose mobile data. However, I can still make calls. I can change it back to USA Baseband (I live in Europe) with *#*#4636#*#* --> Information --> select baseband --> 'USA Band'. After that I'm unable to make calls, but mobile data works fine again.
Have to remark that I unlocked my phone BEFORE there was a known backup method of DRM keys, so they're lost forever. I'm trying to find out if my problems are related to this. So far I ruled out:
- Recovery
- Rooted yes/no
- Unlocked/Relocked bootloader
- Different baseband versions
My only solution is to go home, reinstall baseband and all works fine again, till my phone decides to drop signal again. It's starting to drive me nuts. Any advice? And why can I only select 'USA Baseband' from the service menu?

NO it's not related to DRM keys.
I unlocked before the exploit as well and no issues so far :good:
My question is: why are you using a USA rom if you are unlocked?
Flash an european one and root it via recovery (by flashing the supersu zip).
To get the recovery you can install Androplus kernel or dualrecoverykernel by NUT.
I do not run an USA rom. That's my whole point. I run a Greek rom, because that was my original rom.
I still can't get it to work properly with custom kernels. It doesn't matter which I choose, mobile data drops permanently after some time (deep sleep) and I can only fix it if I refresh my baseband, because there is no option in the service menu to reset to European baseband, only to USA baseband, which will Break the call function

Ok, sorry for the misunderstanding then
It seems a hardware problem :crying:
Sorry for the stupid question: have you ever tried another SIM from another carrier network?
EDIT: wait, I see your operator is Vodafone NL... do you know that for your network (and some other Vodafone network) a .79 version had been released on December, 22th?
Maybe that's the point!

Thanks for the help. I am aware of that, but only tried to flash the baseband of that version. Will try to make a flashable prerooted rom and will report if it works. It is quite hard to test, because it only seems to lose baseband if I move a few miles physically.
I don't own another sim and I currently know nobody who also owns a phone with a nano sim, but I will try that as soon as I can. On that note I have to remark that I cutted my micro sim to a nano sim size. Could be related to that.. Just trying to narrow it down for me and future users who also experience this problem..

Cutting a sim from micro format to a nano is never easy like from normal to micro, because the chip is just beneath the metallic contacts.
Yes it could be the reason of network issues.
I would extract the sd card too, as sometimes it can give odd behaviours.
By the way, I would exclude anything related to unlocking the bootloader and losing the drm keys.
And yes, I would begin with flashing a whole vodafone NL stock rom.
Try and keep us informed.

Tried, but failed. Back to my old ROM. I'm running out of possible solutions.
EDIT: I pulled out my SD-card and turned off WiFi on location and so far (24hrs) I'm still good. I might be related with that.
EDIT 2: Problem was not SD-card/WiFi/SIM related. So far I narrowed it down to my phone not being able to pick up a proper WCDMA (3G) connection. Because of that it refuses to switch back to 4G mode and shows Network type: unknown. Haven't found a real solution apart from *#*#4636#*#* --> phone-info --> set network to CDMA/LTE auto (prl) and wait for the radio to reset and switch it back to GSM/LTE auto (prl)
I have similar issue with Sony Xperia Z3 Compact D5833 Indian Variant
Baseband and IMEI have become unknown
phone keeps on restarting in loop
after flashing with flash tool it starts but without Baseband and IMEI
SIM works on other phone but no SIM works on this phone
Tried multiple FTF from XperiFirm
How do I get it back to work?
EDIT
Next im going to try : https://forum.xda-developers.com/xperia-z/help/solved-help-xz-bricked-baseband-unknown-t2350795
please advise if i should try or is there a different way?

Change CSC to Germany

Hello Forum!
I bought a Galaxy Note8 Duos on eBay.
After one year I noticed that it originally came from Singapore and not from Germany.
So on CSC I have SIN/SIN/XSP instead of DBT.
Updates are not released there as regularly as in Germany.
How can I change the CSC number without rooting the device and Knox still working?
I have already tried to reinstall the device using Odin and the German CSC file.
But it didn't work. It remains on Singapore.
This question has been asked many times before, but all the answers don't work for me.

I have now by the Singapore Rome no disadvantages, but I would have nevertheless whole gladly a German one.
Is there also a good way to get the bull**** apps like Facebook & Co. To uninstall?
I don't need them and deactivating them is not enough for me.
Does it still work with a PC, USB cable and ADB?
- Hoerli
You may first find the newest german firmware adequate for the carrier you are subscribed to, then flash the entire firmware, not only csc, also use the newest ODIN version, that should work
Go to Sammobile and lookup Galaxy Note8 N950F and download the firmware. Once you follow the instructions, you will need to select the CSC that it comes with and NOT HOME CSC as this will keep your original csc. NOTE this will factory reset your device as normal with any csc change.

That's exactly what I did. But it remains with Singapore
I know this thread is a bit old, but does anyone happen to have a working solution in stock now?
Simple if it is a multi rom and has the desired country code on the package. Install a sim card of the country you are/want and factory reset the phone at startup the phone will ask you to change csc to the sims country code that has found if you press yes to change it will reboot and boot on recovery and will apply the region/country csc of the sim card you have. After the boot up your phone will be XXX/XXX/YYY where XXX is the original csc and YYY is the csc of the sim you had installed.
Carefully you will need to reset your phone to achieve that so backup before doing it .
Hope it helped
P.S your desired CSC must be on the original package of the rom installed on the phone, aka a multi rom. Let's say on a N950F international unlocked phone.
Done!
I've finally made it.
My approach:
1. all data backed up
2. the DBT firmware flashed with Odin
3. the device switched off
4. factory reset and wipe of the cache and Dalvic
5. smartphone with SIM inserted newly configured
... it didn't work until here and CSC stayed on Singapore.
6. Dialed the following number over the phone:
*#272*My IMEI number#
7. DBT selected
8. At "Select type of Install" I have chosen "Sales Code Change"
9. smartphoea was restarted and deleted
10. after the new setup I now have DBT/DBT/XSP
Now I'm waiting for the Android 9 update.
Interestingly now the phone number *#272*My IMEI number# does not work anymore.
Note to self: the morale of the story is to start at Step #6 (after manually creating a backup).

I'm not sure if steps 1-5 are necessary for step 6 to be done.
Insert a German sim card then reset the phone. When it boots up for the "first" time with the sim it will recognize it and it will prompt to change the csc to the sims country code (dbt) if you press yes then it will go to recovery and change to DBT CSC and you will have DBT/DBT/DBT .

It's not working.
I tried it several times.
I also reinstalled the firmware 3x.
I also read several times on the net that you can't change the last digit without rooting the device.
I can no longer dial the CSC number.
There is always "Unknown MMI code".
Dunno mate what is happening. I had my note send to Poland for burn in on display when it came back it had DBT/DBT/XEU the only solution to change that was with the factory reset and a German sim card. On Munich service center from Samsung they flashed 3 times the german ROM and nothing was happening, after resetting the phone it asked on boot up to change the csc to DBT and that's it.

Question CSC for UK

I can't remember what CSC code the UK Samsung tab s8 ultra came with I flased the EAX firmware and don't have the oem unlock option I've waited 7+ days.
Does anyone know what CSC I should be using in the UK?
If someone has an unmodified UK Samsung Tab S8 Ultra, you can find this information in Settings > About Tablet > Software Information > Service provider software version
@fkofilee or @Redswap007 any help for @Jono0907?
EUX for UK @roirraW "edor" ehT

What is CSC Region Code and how check witch is in my Samsung Galaxy device?
CSC is short for "consumer software customization" or "country specific code". CSC is an essential component of Samsung firmware files and contains custom settings, system configurations, locations and geographic elements such as system language, APN settings, logos, and carrier applications...
www.hardreset.info
BTU and XEU are 2 of the used CSCs previously for the UK...
These have been compiled into the EUX CSC
Also for OEM Unlock.
EUX Software would be ideal But also you need to sign in with a Samsung Account and also if 4G / 5G Edition you also need to put your SIM in.
Then it should make it show up. Had same issue as you before.
This is what i have on mine. By the way, received the keyboard last week
Yeah this is really weird been on about 8 days now still not showing up did a odin flash of the EUX firmware signed in to Google and Samsung and have been using it daily. I did have the XAR firmware after sorting out another problem but can't see why that would be stopping it.
I just took a screenshot of download mode to see if it has anything I'm missing
Really stuck without being able to root this tablet stupidly relocked the bootloader trying to fix another problem and have never got oem unlock back willing to pay anyone who can help me

Tried a factory reset? If it's a model with a SIM card, try taking the SIM card out, factory resetting, and then connecting to Wi-Fi, then hopefully OEM unlocking will show back up. If it doesn't right away, try rebooting again. If so, then I'd actually re-unlock the bootloader before putting the SIM card back in.
No promises, just suggestions.
WiFi only model Tried 2 different default EAX firmwares each time waiting over a week for oem unlock after flashing in case the "rmm" problem is still there

Maybe call Samsung to try to find a solution? What's RMM? Remote Monitoring Management?
rmm state was from the original error. When i rooted the tablet originally i rebooted and the Tablet said it would not boot because it thought the tablet was on finance and you aren't meant to root tablets until you fully own them. I bought the tablet without finance. Stupidly relocked the bootloader to try and fix it and haven't been able to unlock it since. Do we know if the american Tab S8 Ultras (Non 5G) can be unlocked? Trying to rule out if it was running an american firmware at one point.

Yes, my American Tab S8 Ultra Wi-Fi model was able to be unlocked as normal. I just had to connect to Wi-Fi, then OEM unlocking was available in Developer Options (before connecting to Wi-Fi, OEM unlocking wasn't even displayed as a grayed out option).
Then I unlocked the bootloader and rooted and all is well.
Sign in with a Samsung Account and then it should appear. Happens to me.
Still no luck Was already using my samsung account its connected to my phone/earbuds and all synced together but tried removing it and creating a new account with no luck. Samsung wont touch it because its been unlocked already. Not sure what to do now.
Reflashing with SM-X900_EUX_X900XXU1AVCD_X900OXM1AVCD_X900XXU1AVCD_X900XXU1AVCD.zip Now this will be the 4th time ive reset it and waited 7 days.
The only weird thing I have done other than relocking it stupidly was the one firrmware i flashed was XAR. I don't know if this is causing me problems.
Did you ever find a solution to this? Having the same problem with a UK tab s8 ultra and can't get the oem unlock option to show up no matter what I do
Try 7 days wait after reset
Itll eventually appear. Also make sure you sign into a Samsung Account and it should also help
Same issue before.
