[Q] Bricked Galaxy Mini while unlocking

I followed a "SAFE UNLOCK" method that in the end made my phone stop booting.
Since "Download mode" was still working I flashed using Odin the S5570BVKT4_S5570OROKT2_ORO firmware (Romanian ROM from samfirmware.com)
My problem is that although Android boots, the Phone feature is dead.
*#1234# says Phone: Unknown
What can I do to fix my phone?
Thanks

Try dialing *#06#. Is it showing you the imei no. If yes try reflashing the firmware but wipe data and reset it in recovery mode first... but if its showing unknown or 000000000000000. Use it as a mp4 player now because you modified files in the efs partition.... which keeps info about imei... or if you made a backup of efs before unlocking it you can restore it....

You might have gone wrong while working with ODIN.
Click here to see a list of stock firmwares (with bootloader removed - no hard brick risk) and download what you wanted.
Then flash it using ODIN following the steps correctly. See the tutorial here.

I've tried to run EFS Pro 1.81, 1.82 and 2.0.26 and I it couldn't connect my phone. My mobile is still working all right, but I want to make a backup of the EFS info just in case. I wonder whether if somebody have successfully backed up the EFS folder.

Well the file you will pull from your phone is the efs partition, you no need to look into it, you just need a hex editor to look the code
No need of editing anything
And for the backup purpose just backup the efs file you will pull (backup means copying it to a safe place)

You mean the bml5.img file? If so, I've done the backup already. Cheers!

Insert SIM / no IMEI / baseband unknown after official JB update

hello...after the update from GB to the russian JB ROM i have these problems: insert SIM,my IMEI is missing and baseband unknown...i have followed the exact tutorial..i have had galaxy ace before so i'm not a total stranger to flashing thru odin...i have tried wipe data , wipe cache, factory reset, rooting and deleting dalvik cache and nothing...i reflashed back to GB..worked fine but with the same problems...everything is working fine , wireless and bluetooth...i can boot into recovery mode and downloading mode with no problems...i have read some things about the EFS folder...i didnt do a backup of it...any advice?

If the imei is missing, you destroyed the device. You can try to get it back. There are a few guides. Or you can get it serviced..

You can install jb root it and reset binary counter. Then flash stock gb. Find method in development threads. And den get it serviced. They will replace the motherboard. Hope you have warranty. Else it's 6k for the service. I got the same problem and followed this procedure.

do you have your old imei anywhere? like written down or as a backup file? there are apps for imei backup and restore in the play store... if you dont have a backup of your original imei i don't thinm there is any way of recovering it.
Gesendet von meinem GT-I9070P

If you don't have backups you can't recover it, you will need a service box or send back to samsung, but that's risky, because that's not covered by the warranty.
Which files/folders have you copied exactly ?

I've overwritten entire EFS partition thru dd.
I do not had backup and the partition was already corrupted.
Sent from my GT-I9070 using xda app-developers app

The original imei should be available on the box in which the phone is shipped. Search it. Then you will have to dd the efs partition as an image file and edit the imei in it using hex.
It's difficult, but your original imei can be recovered!
I do not respond to tech support via PM

I tried it on my phone (ace 2 - same novathor chipset) but after I flashed a new efs my imei still was the same.
Are you sure you didn't changed anything else ?
Also you can try this: *#197328640# in dialer, and search for "NV Restore" or "NV Rebuild" option (for me it's under "Common") I'm not sure how it works, but maybe the phone has some backups on a different partition.

I've tried to delete every file on /efs but cloned IMEI remains.
I think that IMEI is stored or cached anywhere else.
I already tried that option (NV Restore).

Modemfs also contains some files from the EFS partitions RFHAL.DEF/RFHAL folder.
Have you flashed a JB or any firmware with repartition ?
I noticed from a log file in /efs/pre_recovery.log, when the device is repartitioned there is an additional check if the imei is valid or requires a restore.

Exactly, my 3G stopped working after downgrade using Philippines ROM and I tried check repartition.
My 3G started to work after I copied modemfs partition from my friend device.
Do you know how to recover from that?
Sent from my GT-I9070 using xda app-developers app

Well if you don't have backups it's difficult because I can't even tell where the phone stores the imei, or how does it work.
Of course it's possible to reverse encryption and edit the files from your friends phone but it's VERY difficult.
It's clearly uses a different method, because there is no nv_data.bin (on other Samsung devices the imei/simlock/product code are stored in this file).
If I find anything I'll let you know.
The cheapest sollution is offered by this guy: http://forum.samdroid.net/f70/repair-imei-s2-5729/
Or a very risky sollution: Brick the device and send back to the repair center if it's still under warranty.
Edit: Try flashing that rom again with repartition and see what happens, also check the efs/pre_recovery.log, for me says "valid IMEI & skip restore" so obviously there are at least 2 places for the imei, that's why for me doesn't changes even if I wipe the efs.

I've lost the imei some months ago and i've solved flashing the italian GB firmware, but you can also use another firmware.

You probably flashed a wrong modem, but basically you didn't lost your IMEI, just the modem part wasn't for your device and it couldn't get the info.
This usually happens when you flash a firmware from different region, for example i9070L rom on i9070 device.

There's no way to regenerate/restore the modem part?

I wrote this to giagia96.
In your case I don't know why the phone "decided" to change the imei.

[Q] SGH-t849 JB ROM Unknown Baseband?

Hey guys. I flashed a JB 4.2.2 ROM for the GSM tabs and all went well. Except when I flashed the T-Mobile modems JJB and JL3 it comes up as unknown baseband and I get absoultely no signal when I insert my SIM card. Am I missing something?

Perhaps your IMEI is bad due to corrupted EFS. Find the backup in sd card, and copy and paste back to /efs

Find in your internal or external sd card a backup folder.
See if there is an efs folder.
Copy the entire content to /efs replacing what you have in there. Reboot. See if IMEI reappear.
If not, you need to try to flash stock rom using odin.
Use overcome method found in my signature.

no words to say thanks for your help
may you have success in your life one after the other,
thanks again and best regards,:good:

You are welcome.
You may want to try again with cm10.1 or any higher, as long as you know how to restock.
About efs backup, it isn't done by cwm.
When you flash cm9 or 10, it backs up your /efs to a safe place.
Usually in /sdcard/backup/
Or in /emmc/backup.

[Q] IMEI NULL/NULL Baseband UNKNOWN

My brother owns an AT&T cappy...n after some months of custom rom flashing, he gave me the phone asking me to repair it.
It has stopped reading the sim card, when i checked the imei of the device it gave me a popup of IMEI null/null..also the baseband version is also unknown..
I have many a times flashed the stock rom as every thread about my problem is telling me to do..
also used galaxy s unlock, app for factory unlocking GS devices..but know success
i seriously want to give it a last try before handing it over for a repair outside..
any help would be highly appreciated!!!!!:crying:

Yep, usually using Odin or Heimdall to return to stock firmware should restore the imei. Have u tried to flash to Stock KK4 firmware yet ? The Odin or Heimdall One Clicks for i897ucKK4 can be found here... http://forum.xda-developers.com/showpost.php?p=18370912&postcount=3.

yess!! many a times..but no success

I also wanted to add that :-
during the galaxy s unlock method..i usually get the busybox problem error...though i've installed and verified it many a times

With all the months of flashing that ur brother did...i would think there would be a backup of the efs folder on the sdcard?? Some roms and kernels, when flashed, will create the efs backup for u.

yess!! hopefully dere's an EFS folder.. but i was too bugged up when googling for the method for restoring it..
n also i'm not sure whether the folder is fine or corrupted/messed up..
also i'll be greatful if i'll get to know the easiest step by step process of restoring it.:good:

If you check on the internal sd, you'll see an efs folder. Should probably take a look for yourself before asking those questions
