[Q] GT Tab 2 P3100, IMEI lost, no efs backup, - Android Q&A, Help & Troubleshooting

Hi,
I am a NOOB.
I have a GT P3100 with no baseband and IMEI,
I lost EFS folder trying to flash slimkat and dont have a backup.
Is there a way to repair it without a box??
Thanks in Advance.

First thing to try is just re-installing the stock firmware via Odin. Just because it is not displaying or working does not necessarily mean it's lost for good. If the official restore doesn't work, then you might be need the box.

Thanks

Did you restore the stock rom via Odin yet? Or you're saying you did and it's still not working properly?

It's common to need to factory reset after a stock firmware install through Odin.

tried odin and factory reset also

This flashing stock, did you do it through CWM or ODIN? If you have not tried ODIN yet I would go that route, could just be you need a stock modem.

i am such a tard.. i havent backed up the efs... i did so now after the mess ... i believe there must be someone with tips and a small hope, btw restoring efs make no difference at all, as dont have correct files.
The EFS is fine if you have IMEI, if you have only flashed each ROM once through ODIN you have hope. Try an ODIN flash again. Can you get to recovery to do full wipe first?
Try EFS Pro Here and download to your PC then run it. You will probably need to use your own wireless to get Busybox (free on Play Store) and run it on your phone - if the phone will not go to wireless, DL the files to your PC then copy BB over to the phone in Windows Explorer and run it on the phone.
Then run EFS Pro on your PC (with phone connected by USB, but it will prompt you) and there are a couple of options there to try to see if you can recover things. (NV Recovery and Repair NV Data) - I think the NV Recovery uses info on the phone (.bak file) while repair tries to rebuild the info.
Good luck. Maybe read through the thread first or contact the thread OP if you have questions about EFS Pro processes...

I don't think this will help with the Serial issue, but maybe for the service all you need is the APN/Service info from Vodaphone? Go to [Settings] [More Settings] [Mobile Networks] and check both Access Point Names and Network Operators.
I flashed a ROM and found I had problems so I went to a Telstra page, entered my phone number and it sent me a text with a security code - when I entered that it sent me an install that connected all my services again. Maybe Voda has similar? Or even just a page with APN info?

guys help me out... i am stucked ... any tips? i am willing to try "almost" everything to make it work.
Beyond what I know so far, sorry. If it was me I'd be making sure I have back-ups of everything I can think of (Data, System, Nandroid, EFS) then I would start from clean phone - wipe everything in recovery, factory reset etc. then load as close as possible to the original Stock for the phone. If that doesn't do it, with official stock and counters etc. I'd go to vendor and ask what gives. I'd start with the service provider and if they can't help, phone vendor, then failing that, Samsung.
Maybe some of the more experienced here can assist otherwise...

[Q] Phone cuts off and freezes after firmware changes

I've had a search of the forum and couldn't find anything similar to my problem.
A few weeks after I first got my phone, JellyBean was leaked for my Samsung S3. I managed to get it on my phone and it ran OK, but was slightly buggy. A few days ago I decided to put back on the stock firmware, so I went to Samsung-updates.com and found a suitable file (so I thought) and installed it using Odin. It turned out it was O2, but in Cheqk the phone also didn't start up 90% of the time, froze randomly and cut off a lot. I then found the O2U software (O2 UK) and installed it with Odin. The language was correct, but I'm having the same problem: My phone is slow, crashes etc.
I used Odin 1.85 and 3.07. I have the Samsung S3 UK Version (no 4G) and it's on O2.
The model on the back says GT-I9300.
My question: How can I restore it to original firmware (out of the box) so it's exactly like new? Thanks for any help in advance.

[Q] S3 I9300 bootloop after backup and restoring efs using Nitrality

Hi
I'm having a problem where my S3 go into bootloop after backing up and restoring efs using Nitrality
I can go into recovery mode and download mode
I have tried Factory Reset, delete cache and flashing stock rom 4.1.2 using Odin, it was succesfull but my S3 still go into bootloop
Any tips?
Thanks
are you sure you flashed the correct rom? are you sure it's the i9300?
if you flashed a stock rom, did a factory reset, and it's not working, send it in
I forgot to mention that I've also restore my backup through recovery mode and the bootloop problem still exist
I'm thinking about bringing my phone to Samsung Service Center but I can't because my binary counter aren't zero
Is there anyway using triangle away through recovery mode or Odin?
I think I've flashed the correct rom because I've used it before
Thanks
Just did a quick search and came across this. It says its a solution, i guess you have nothing else to loose.

I'm afraid i don't, a long shot but you could try flashing a 4.0.4 official firmware to see if that does anything. i had the same problem with my Tab 2 (not saying that this will work on the I9300) and i flashed back to 4.0.4 let it boot, then rooted it and flashed up to 4.1.2.
Good luck.

As i said above, my problem was with my Galaxy Tab 2 P3110 not my Galaxy s3 I9300 so which Rom i was using would be irrelevant to you. I was however running 4.1.2.
Hope you manage to fix it.

I know that, it's just that I heard Samsung blacklist old bootloader on 4.1.2 update so you can't install older bootloader
that's why I'm kinda afraid this trick wouldn't work because of it
Thanks for your help
Well, I was using the sungsonic rom on my Tab 2. With my S3 I did run 4.2.1 and my bluetooth and wifi AP didn't work which I read was possibly a bootloader issue and the fix was to flash back to 4.0.4 with odin and rooted then flashed to 4.1.2 and that fixed it for me.
Give it a go and let us know how you get on.
I've just flash my phone using ICS stock ROM and it work again
but now I have a new problem
1.my stock lockscreen doesn't work
2.when I press the power button it turn off my phone instead of giving me an option to turn off, restart, go into plan mode etc
3.I can't use my sim card because the phone doesn't start the program where I have to insert my simcard pin
Any idea what I should do now?
not sure about those. but for the sim have you gone to settings - security - sim card lock and had a look at the options there?

I can't do that on my S3 because my sim is locked
but I've managed to do it by using my other phone
I've disable the simcard pin security, now I can use my simcard on my S3 because I don't have to enter the Pin again
Thanks you've been a great help to me :good:

[Q] Galaxy S3 stuck at boot. Failed to mount Data, failed to mount EFS

Hello, I have a Galaxy S3 (GT-I9300) phone that is not feeling so well.
On startup it freezes indefinitely on the Samsung boot logo.
I am able to get into recovery and download mode.
In recovery I get errors - unable to mount Data, and unable to mount EFS.
The phone is recognized by the computer, both in Kies and Odin so flashing is possible.
It is not rooted and completely stock. Problem is that I don't know what version firmware it had.
There is unbacked information on the phone I'd like to recover.
What I've tried: Within Kies>Firmware upgrade and initialization (second option under tools) I enter the model number and then the serial, but I just get a message along the lines of "please check your model" (I entered GT-I9300).
The phone is generic international version from 2012, untouched (version-wise) since.
I very much appreciate any idea that might fix this. How can I find the right firmware? will it erase my memory? how can I restore the EFS partition?

Will it work even though it is intended for Android 4.3? The phone originally came with 3.0 or 3.1
Also I believe flashing firmware will not fix EFS?

YES! the new firmware fixed it completely. It is a bit slow, but alas that's probably the phone itself.
To anyone looking in the future:
This problem was caused by a faulty battery - the phone would turn off while working all the time, and eventually it corrupted the data and efs partitions. To my luck upgrading to new firmware fixed the problem.
Thank you.:good:

Same here (Think we done the same thing with the Marshmallow 6.0.1 leak) I backed up, but the new version of TWRP I have has EFS as a separate option, I never even noticed and never backed it up.
However I Flash with smartswitch, and after reflashing the bootloader with odin and a Root Kernel, I can boot into the device and using root explorer, I CAN see my EFS folder. I deleted the .nv_data.bin files and changed the .nv_data.bak to .nv_data.bin (was an older date) and I now have the network options back but a generic IMEI and can't register on a network.
I feel SO close to getting it up and running, but if smartswitch can't help, not fully anyway, I'm not 100% I can be rescued either.

I've called to my local service center and they said that they will reflash firmware fo 450 CZK (about 17 euros) and It will be done in 1 hour 30 minutes. So I will se what they can do with it. I've tried everything... and right now I don't know what else I can do. But If you figurate out how to fix it let me know Thanks!

I got 3 old smartswitch backup and i find a file with the imei and everything , do you think its possible to backup this files ?
You CAN recover your phone with smartswitch, there is an emergency recovery function with a IMEI and SN input option, some users who used the same threat (android 6.0.1) and has lost their efs partition reported that smartswitch worked.
I've done this procedure too for some weeks to recover my phone an everything is working fine.
possibly with root explorer
