baseband is unknown.i flash aokp again that may be that correct it bt didnt works.can i install gb stock safe directly over aokp 40# or again hv to restock.
Sent from my GT-P1000 using xda app-developers app
you have to restock when coming from MTD rom like AOKP or CM9.
even for nadroid restore you have to restock then restore.
when restock, it is best using GB-stock-safe.
use its pit file and it also has modem files.
Edit, are you referring to GB-stock-safe when you said "overcome rom"?
Overcome ROM is a different thing.
yes gb stock safe i was about to correct that.i install bml my mistake due to rom naming confusion
now ll gb stock safe help in getting baseband?

honestly I don't know about efs.
I read of people losing /efs due to bad kernel, but got it back with good flash.
I don't get it because I thought /efs once is deleted it is gone unless there is backup.
Anyway, you have checked your sdcard, no backup?
and GB-stock-safe can be flashed coming from aokp.
that is how we restock.
i didnt create any backup bt there is auto back up one with name efs and another with efs-294 .
and where is modem file for gb stock safe.it is not in zip file i download.only rom,pit file and overcome kernel.

even if you delete efs folder, android will generate a new one with a different imei, its a real problem because he will find a hard time with his apps (paid ones) i tried the new efs once and i can't use my Samsung paid apps anymore, when restored my old efs, it works again.

efs.img
Hello.i tryed to backup efs partition on tab p1000,and got the 2gb efs.img file.As i know now,its too big.Is it possible that image contains /efs folder in it?And if yes,how can i restore?
Restocking didn`t bring imei back.
What did you use to restock?
i haven't heard of a 2gb /efs backup before. sounds like you should restock using a proven method like Overcome. Maybe you should try this out:

like many, i also lost imei once, and this rom brought it back.

So I'm going to assume that my IMEI is gone as the one that is listed under 'about phone>status' is different than the one printed on my phones manufacturer box. The one listed appears to start with 0049. I have verified the APN settings on my samsung galaxy s captivate are correct per my carrier - Straight Talk. Any help is appreciated, thanks.
I currently have flashed,

Thanks for the reply, I figured that was a possible solution but wasn't sure about copying entire folder. I had read posts about copying just the .nz_data.bin. I appreciate your help.
hmmm. Still seem to be having some trouble. I had flashed with odin one click to gingerbread 2.3.5 and made a copy of the efs folder to the internal storage using root browser. I've moved the nv_data.bin & imei folder & nv_data.bin.md5 over and now it's reporting the IMEI as unknown. I've played around with permissions setting the user:group to radio. and also tried 1001:radio w/ rwx---. I also tried clearing the dalvik cache afterwards in hopes that it would rebuild stuff. Not really sure what I am missing, anyways I'll probably flash to gingerbread again and make another backup to the internal storage with file manager in CWM, I'll then reflash to CM10 JellyBean and try to move again. Let me know if I am missing something.
Also do you have any idea why my efs partition is getting corrupt / overwritten when I am flashing? I've been following instructions in the thread for CM10 JellyBean 4.1.1 and It seems the 3 or 4 times I've flashed this devilkernel rc3 and then the cm10 jellybean v2 + apps + su package that my efs gets messed up. Thanks again.
Guys,
I just updated with the CM10 nightly and I am getting a prompt on bootup that my IMEI is not valid. The IMEI is not blank, and isnt something like 0123456789. Is this a big issue? My calling and texting are working fine, as is my mobile data.
Thanks
The same happens to me. I did an efs backup with root manager but is there any risk? Could someone explain please?
I backed up with cwm before loading cm10 0823. And did an imei restore from Nitrality and it says successful. However I still get an invalid imei on bootup

Well, in my case, my father's phone lost all efs backups, and nv_data.bin is corrupted (regenerated new one with default generic IMEI).
So, there is nothing to restore from. Reflashing to stock 2.3.6 JW5 firmware didn't help. So you think that I will have to reflash to 2.2.1? How so? I don't understand how older firmware may help restoring correct IMEI...and I don't own JTAG, z3w or SPT boxes...
And for morrons - no, there is no .nv_data.bin, no nv_data.bin.bak, or similiar...only new nv_data.bin(md5) with default, generic IMEI.
Is there any way to restore it? if somebody start to complain that I am thief, I can prove by photos of original phone box, and buying papers I have (my father gave them to me for this purpose).
And no, I don't have to steal anything, I own SGS3, SGS2, SGS, SGT10.1....so stealing another SGS is not an option for me
I just want to restore that phone to it's stock state (and then reflash again with CM10).
Anyone?

Why are you so confident, that JVU will regenerate /efs?
as said before, my father was so genius, that he has wiped /efs partition out. I have restored some data, but without proper IMEI, so now I have generic one. I still do have old JVU package somewhere on my NAS, but I do not understand, how old firmware may help, because I am without any /efs backup anywhere... is that firmware customized so it checks and regenerates /efs if its damaged? If so, why is this feature missing from latest full JW5 firmare? Please understand that I know what I am doing, but right now, I have empty hands...without JTAG, z3w or similiar low-level gadget, it is really hard to restore proper /efs on my own...
But thank you for links, I will take a look on them...
More Clues On Fixing IMEI Issue (solved for me)
In my case I upgraded directly from Froyo to CM10.1 and got then same dreaded 'default' invalid/corrupt IMEI=004999010640000
On inspection of the /efs files present it was clear they had been created by the system in response to not being present.
Following advice in this thread and elsewhere I downgraded back to Froyo (XXJPU) and like magic my correct IMEI re-appeared but as soon as I upgraded up to CM9 it changed back to the invalid default of 004999010640000 again.
To cut a long story short I downgraded back to Froyo (XXJPU) again, flashed a recent CWM recovery and booted into the recovery. I then used ADB to get a (root) shell prompt and discovered that the correct /efs data was being mounted from the device /dev/stl3 and at this point I was able to tar up the contents of /efs and safely make a backup. I then upgraded to CM10.1, restored the correct /efs backup and rebooted.
Happy with correct IMEI now
I am not sure what is going on but I am speculating that the big jump from Froyo to CM10.1 bypasses come critical intermediate ROM build where the correct IMEI data is copied from /dev/stl3. CM10.1 assumes this step has taken place and makes no attempt to get the original IMEI data.

Exactly that. Same goes with going from Gingerbread to Jelly Bean.
That critical intermediate rom... Is CM9
In other words, to safely preserve your IMEI,

Hi guys first and foremost, thank you for reading. I must say this is as a very informative forum with lots of good people in it. This is my first post, and i am an absolute noob so please bear with me. I am posting because i have tried my best to search for answers pertaining to my problem but to no avail, so i hope someone can really help me out here!
so i have a P1000 and bricked it before but anyway am now running
Sapir-10-20121118-nightly-p1-erezak
problem is, the baseband is unknown. which means my sim card does not work. WiFi works fine but i put in my sim card and it doesnt detect a network at all. I have also noticed that Whatsapp is not supported and with the rom, my phone gets warm at the back and power depletes rather fast.
i have doubled checked with a friend who has an unrooted P1000 with the original rom and he told me his baseband was "P1000-DXJPE"
i have gone here
http//wiki.cyanogenmod.org/wiki/Samsung_Galaxy_Tab_(GSM):_Support_Downloads
and downloaded the DXJPE modem.bin file and tried to put it in the /radio folder but nothing has changed.
So can anyone help me on this? as in, tell me, in detail how i can make my phone work properly again with data/3g/mobile. Or i will just have to use it as a Wifi tablet.
I read this in the Sapir development thread, and i quote
"Originally Posted by _Derk_
No, just the other way round.
I recommend to have the correct modem.bin (for me JPZ) stored in SD card.
So in one of the cases where you have baseband unknown like now you copy it to /radio folder, even if there is already a modem.bin (which you delete prior). Then just assign the correct authorisations (RWXRWXRWX / 777) and it should work.
Bye,
Derk"
So if this is my answer, can anyone tell me how i can go about doing this? I have no idea what it means!
Another question; is this rom power conservative? My stock GB (or is that Froyo, i cant remember) rom seems to last quite awhile as compared to the Sapir rom. Even if i don't use it, it drains power really really quick in like, a day? Is this normal?
Big drain is normal when you have bad baseband.
The thing you quote, is exactly the same as your own method.
The difference is Derk suggest jpz modem.
So download jpz modem and unzip and place it in /radio
For permission, use root explorer or ES file explorer.
Click long on the file and access its properties, and tick all.

Hi Priyana thanks for the quick response i have already gotten the JPZ modem.bin and put it in /radio. I am actually using Solid Explorer instead of ES Explorer. Root Explorer does not work for some reason. I have also changed the permissions in properties as to what Dirk has mentioned,
RWXRWXRWX / 777
sadly, nothing has changed. What do u suggest i do next?
There was a build in the past that put it in /system/vendor/
Try that?

Done that. Doesn't work
Has this got anything to do with the Owner & Group for modem.bin? Both are now set as "0:root". Both can be changed to "1000:system", "1001: radio" and "1002:bluetooth".
So by right if i go to "settings/about tablet" i should see the baseband version if everything is ok right?
Yes, should be showing under baseband. Don't know what is wrong, maybe you want to flash different nightly.

Yes i did reboot. I am actually trying to follow your guide to re-stocking. Unfortunately, Odin does not recognise my P1000 in download mode.
This is quite the disaster isn't it? I am ****ed aren't i. :crying:
Noob suggestion,
Wipe everything, factory reset, partition cache, dalvik cache, battery stat. Fix permission.
And reflash the ROM again, after that, reflash the gapps, and reflash the modem. Maybe it'll work.

Flashing modem is really totally unnecessary and leading to confusion if people grab the wrong flash able format.
In stock ROM when we have bml partition, the only way to change modem is via Odin or cwm.
In mtd based ROM, they sit right there in /radio/modem.bin
Odin cant detect the tab is indeed quite weird, but could be driver issue.
For now, try flash cm10 instead?

You need to check if you have IMEI as 004xxxxxxx (bad IMEI) or the normal 35xxxxxxx.
if bad imei, it is corrupted efs
And in sapir thread we talked about it, use search.

Hi Experts,
My device is GT-P1000. I was able to flash the nightly built from cyanogenmod site. I flashed cm-10.1-20130609-NIGHTLY-p1.zip. By the way, I came from AOKP ICS rom.
All is working well for me for the basic tasks that I've tested except that it can't detect our mobile networks here in Singapore which is pretty much a deal breaker. Wifi, bluetooth, etc. are okay. You can see in my attachment that it can't find any GSM network even if I search manually. Is this rom not compatible to Singapore local telcos? Did I miss anything? May be you experts got some ideas.
I have searched the android development forum for CM10.1 Nightly but can't find any relevant solution. Hence, I try my luck here if any of you guys experienced the same issue and was able to solve it.
Thanks in advance.

What is your IMEI showing? If not 35xxxxx, say unknown, or 0049xxx then it won't work. Unknown is due to broken modem.bin. Wrong IMEI is due to corrupted EFS. Either restore from backup found in your sdcard or restock then reflash.

Hi Priyana,
Thanks for your reply. You're correct. I checked the IMEI and it's unknown(shown in attached image).
Correct me if I'm wrong, I need to restore to my backup AOKP ICS rom and then flash this CM10.1 rom again?
Or I need to flash a stock Gingerbread rom then flash CM10.1 rom again?
Thanks in advance,

hi
the best way
flash cm9.1 befor flash cm10.1

Unknown is due to broken modem. Just to to development subforum, there is a sticky thread for modem.
Get the JPZ modem, but don't flash it.
Unzip it, just copy the modem.bin to replace the one in /radio/ of your device.
Use root explorer or similar. Reboot and check baseband again. If IMEI still unknown, better restock.

Hi Jalil,
I tried what you advised but still no luck. The IMEI is still unknown. I even restore my AOKP rom but still the same issue is happening. Thanks though.
I downloaded a stock firmware (gingerbread) and planning to flash it if priyana's advice doesn't work.
I will try priyana's suggestion first before I flash a stock firmware.
Hi Priyana,
I saw the thread that you replied in back in 2012 Oct. Will try your advice. Thanks.
/f
have you also check if you have a backup folder in your sdcard or external sdcard
that has efs folder in it.
Pick the oldest one which is more likely to be the good copy.
Copy the content to replace the one in /efs
Also make sure that you show hidden files in the file explorer, or you will miss important files from that efs back up folder.

Hi Priyana, KasSGT and Jalil,
I was able to fix my device. I did flash a stock rom, root it, and then flash the CM10.1 rom. I now backed up the /radio directory just to be sure.
