[Q] HELP! Samsung Galaxy TAB not detecting SIM

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?

[Q] GSM modems/ROMs

Does anyone have links to GSM modems for 2.2 or above roms? All i can find is WCDMA modems. I think this will resolve my problem ive been having for months, which is that all roms/modems here dont allow sim cards. So if anyone has links to GSM modems it will be much appreciated
My carrier uses a UMTS mobile network on 850/2100mhz frequency's, so a modem that supports that is required
Thanks
Doc

wtf are you talking about?
this phone IS a gsm phone.
the only way to get data/voice on this phone is WITH a sim card, so what are you talking about that every rom/modem doesnt allow sim cards?
do you have ANY idea what you are on about?

Any rom I flash my phone with I can't use a sim card after that. The phone just says no service and ALL Roms end up deleting the service menu and it doesn't detect sim card. Read my other post in Q&A forum to know what I'm talking about

You might wan't to check your APN setting. There are a good bit of modems some work better than others in different locations.

So you had a thread open regarding the exact same problem, yet you thought it was a genius idea to open a new one?
Sent from my HTC PH39100

Who is your carrier? You haven't stated it in this thread nor the other from what I read. All I gathered was that you are not i897, and have been flashing i897 roms.
Like stated above your APN settings are probably incorrect for your carrier from the repeated flashings.
If that is not the problem and you know to remove sim card while flashing and also unplug the usb during reboot then you can scratch those off the list aswell.
I'm not certain, hopefully someone with more knowledge could chime in, but is it possible from flashing the At&t carrier roms the phone got locked to At&t, thus not recognizing the unknown carrier's sim card? Try network unlocking the device?
Also, you should probably go back and reread you're other thread, I believe there are very good explainations, judging by your replies, that you just disreguarded.
edit for good measure: you are installing the sim card while the phone is off correct? you can't just take off the battery cover and put it in whenever you like.

I'm doing everything right, and as i said before it does work fine with my carrier (Telecom New Zealand) on android 2.1. I've tried every solution i can think of to fix this, but none have worked. I even tried backing up my working csc files then re-flashing after a new rom but that didnt work either. The phone basically doesnt register that it needs a sim card once it has been flashed. I get the blue circle with the line through it to indicate there's no signal (this happens with or without the sim being in). I am sort of a newbie when it comes to ins and outs of android but i thought it would be worth checking it out if its a modem issuse. Obviously by some of the replies i've got im wrong.
Do you have any other suggestions?
Edit: another thing to add is when i use the caller to open the debug menu (*# something #* ) where it usually has all details about the bands its connected to and batter information etc its completely blank (usually full on 2.1, but blank on 2.2+)

You tried *#2263# ?
Walkthrough:
Settings>wireless and networks>mobile networks>network operator- choose your network<<access point name>(press selected network operator)confirm settings with known provider settings[requires you to search your providers settings] apply. Reboot. Confirm or deny.

*#2263# is the number. At the moment on working 2.1 rom i get:
=BAND SELECTION=
[1] AUTOMATIC [*]
[2] WCDMA BAND []
[3] GSM BAND[]
[4] COMBU BANDS []
I will flash when i get back form holiday, at the moment i am running the stock 2.1 rom fine on my network. From what i remember once its flashed with or without a sim card it wont let me access the network settings, giving me a message like 'network not avaliable' or 'unable to register on network', thats why i cannot access APN settings.
I'll take screenshots and post them around the 28th? Then you can see what i mean.
Thanks,
Doc

Sounds good. In the mean time, under access point names did you try pressing menu key then press add new apn? Not sure if we covered this already.

If the APN setings are locked out use a utility like Tweakker or Apn Global. These programs will bypass the locked out settings and automatically set up APN MMS for your countries telecom. Download from the market by reverting to working rom or using sideloading wonder machine thru your computer.

It appears for your carrier you are missing an access point.

I cant do that, when i try access network settings it asks me to insert a sim card

I had a similar problem. My phone fail to recognize the sim card a few times when the cover was off. My working theory was that the cover helped to "seat" the sim card.
Hope this helps.

[Q] Unable to register phone to the Telus network. How do I fix the problem?

Hi,
I recently purchased a brand new Telus HTC One off someone on Kijiji, and today I tried to activate the SIM card and register it on the Telus network. In hindsight, I should have activated the phone first with the stock ROM, but I didn't want to activate it before I got my case which took a couple of weeks to arrive. During that time I experimented with a few different ROMs, but failed to make a backup of my original stock ROM.
Thinking the SIM card was bad, I purchased another new one today, but I'm still receiving the same results.
Every time I try to register the phone to the network with the new SIM card, I receive the following error messages.

Please let me know.

This is the stock OTA zip. Flash this, remove sim, reinsert sim, reboot phone and APN settings should automatically set.

How do you know the phone hasn't been blocked from the network (reported as stolen)?

I'm starting to wonder that now. I flashed the firmware from the Telus OTA file, and I'm still getting the error. As a last ditch effort, I tried to unlock the phone. The phone unlocked, but I still can't connect to the Telus network. I've done everything I can think of, and now I'm ready to throw in the towel.
If Telus did blacklist the IMEI number, that just means it won't work on Telus right? In theory, it should still work on any other non-Telus supported carrier, correct?

I'm not sure about there, but here the blacklist is shared across all carriers, so it is blocked from all

[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!

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?

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?
