EFS problem hindering flashers?

Recent stability update is not allowing the flashers to downgrade or limited to only roms with particular modems as it is causing to corrupt the IMEI.
Though our clever developers have found many solutions it has become a hindrance to many of flashoholics like me.
What do you think? Can there be a permanent solution to this? and most important why Sammys have done this. I do not think this is some kind of bug. It is done on purpose,like preventing people from frequenting flashing?
what do you say?

I agree with you, efs problem and partition table corrupt are such problems which make people to think before flashing

I am not flashing any rom for the moment.
Do asop roms suffer from efs problem?

After an update my IMEI has changed from what is under battery cover to something like 004999xxxxxxxxx after which I can't make phone calls any more , after checking I've discovered that the EFS file doesn't contain the IMEI anymore, when happened this my phone was not rooted so obviously I have no backup.I've flashed back the original ROM many times but it's still the same.
Do you think there is a way to find a solution to this?

Please give detailed description of what happened like which was previous rom and which rom you are now on and trying to flash....

Latest update is not allowing the downgrade of modems, so please reflash the nordic rom so that atleast you will have your IMEI back. I was on ARHD 17.0 , tried Omega rom which is DME6 and reverted to ARHD 17.0. In the process I lost IMEI. So I reflashed Omega and I had my IMEI
NOw ARHD 18.0 is also DME6 and I can flash it but not below that

Ok will try it.

Just one question please,do I need CWM installed on my rooted phone to flash a modem?

[Q] 4.1.2 to 4.3 Made device un accessible to mobile network

Hello there,
I live in India and my Note 2 is a Poland made and running with 4.1.2 stock ROM non rooted. But the device status was shown 'modified'. Due to that (i think) i was not able to get any updates. So i decided to download and flash 4.3 ROM via odin. I did exactly and flashing was success. But after that i was not able to connect to my mobile network. It shows the coverage, base-band version, operators around me, IMEI...etc. But failed to register on network. Sadly i found that my IMEI was changed. Then i searched in xda and found out few modem patches. To flash them i rooted device and installed recovery. Then flashed DMG1_MODEM and modem_XXDME4 but nothing happened. Phone is still not registering to network.
What to do ?

I assumed that your device history was imei null or efs corruptted which has been fixed under 4.1.2 version.by upgrading the modem it will surelly broke your efs again.use special box to repair the network, nothing else you can do.

you have to flash the factory-image via odin (i think this would be the poland one in your case). you will get this on sammobile.com. with this it recreates your efs including your imei. (had this problem also)
after this you can try flashing a different rom, but don't forget to backup the efs

Is it safe to downgrade from 4.3 to 4.1 just by flashing factory images via odin ?

If you have flashed the latest bootloader MK4,its not possible to downgrade to 4.1 as of now...

He may not if it is a soft brick. As long as when he says softbrick he means that it is not loading past the Samsung log or the ATT logo for example. I was on stock rooted 4.3 as well and tried flashing other roms as well and soft bricked my phone in the process.
I ended up with two choices, load only 4.3 (The STOCK MOD v4 install worked for me just fine - but I was trying to get out of 4.3 tbh) Tried several other roms and all would end in a soft brick.
Finally landed on a stock 4.1.2 UCMG2 rom http://forum.xda-developers.com/showthread.php?t=2388065
After clearing my internal SD and formatting it I flashed it and it worked (took a long time on the Samsung logo but worked!) the wifi is a little flaky at times but it always was on 4.1.2 for me anyways... the key I believe was that this rom did not have a bootloader and modem updated, which was required to properly downgrade after having had previously installed 4.3.
OP try it out and see how that works? Unfortunately I could not find a TAR of this, but luckily I was able to use a microSD adapter to move the needed files onto the SD card so that I could flash in TWRP.

If he was on stock 4.3 and tried to ODIN to stock 4.1.1, then he's gonna need a JTAG.
If he had tried to flash something via TWRP/CWM then it wouldn't have been an issue.

Aaaah OK! Thanks for the clarification on why

You do not need a JTAG service. There is a way to unbrick it of you accidentally downgraded your bootloader from 4.3 OTA.

[Q] Trying to downgrade from 4.4.2 (Cyanagenmod 11) to 4.1.2 stock (T999UVDMD5)

As you'll soon discover, I'm a noob. I stupidly took the OTA update on my Samsung Galaxy S3 T-Mobile T999 from 4.1.2 to 4.3. Since doing so mine and my wife's phone (did the same thing to her also) gets in a mess after being connected to the car stereo bluetooth and prevents outgoing calls unless the phone is rebooted.
So to try to solve this, I rooted the phone and installed CM 11, so now I'm on 4.4.2. This didn't help the issue either and instead is worse at connecting to the bluetooth.
I want to get my phone back to the stock 4.1.2 rom, which I got from sammobile (PDA T999UVDMD5) or at worst back to the 4.3 stock rom (PDA T999UVUEMJC).
This morning I tried to flash T999UVDMD5_T999TMBDMD5_T999UVDMD5_HOME.tar using ODIN 307 but it failed almost instantly with an Fail! Auth message.
I also tried to flash CM 10.1 zip on my SD card using ClockworkMod Recovery v 6.0.4.5 but again it failed almost instantly (sorry I didn't take note of the error).
So now I'm back to CM 11. So any suggestions for how to get back to either of the stock roms?

If you are getting errors in both odin and cwm, it sounds like it is a root issue. In other words, it sounds like the apps are being denied access to root and therefor cannot flash. Both odin and cwm are able to generate logs so you can tell the reason for the fail. Personally, I would recommend flasing twrp recovery instead of cwm since it seems to simplify alot and is a little better for our device. Without knowing exactly why the flash is failing, i would just recommend to try and re-root the phone again.

Did you put the phone in Downloading mode before connecting to the Odin ?
Do not try to flash 4.1.2 ever. It will brick your phone.

Yes the phone was in downloading mode. I couldn't find any posts that thought that I would brick my phone for sure by downgrading so I thought I would try. Could I go back to the 4.3 Stock ROM with some degree of confidence?

Yes you can go back to 4.3 Stock.

So I'm now back to Stock 4.3 by doing a flash via Odin. I did (stupidly) try to then go back to 4.1.2 again using Odin having put the phone in USB debugging mode first but I still got the same Auth Fail error.
Thanks for all the help.

You cannot downgrade like that once you have updated to official 4.3 firmware, no offence but why would you try it even after Perseus said not to? Anyway if you want to go back to 4.1.2 so badly just download a 4.1.2 ROM and flash it in recovery

Thanks for the advice. I think I'll just quit while I'm only slightly behind now and remain on 4.3 Stock. I appreciate everyone's help and suggestions.

Downgrade from CM11 4.4.2 to 4.3 on I747
I went from 4.3 stock to CM11 on my i747 but i didnt like the update. So i am trying to go back to 4.3 however whenever i try to install the 4.3 zip file thru twrp or CWM, it fails. As far as i know there is no odin file for going back. I tried to flash rogers 4.3 file through odin (thinking i would flash at&t modem later) but that also failed.
I would appreciate any help on how to install 4.3 once 4.4.2 has been installed on an i747

You seriously need to do some reading

For One, you are on the wrong forum. This is for T-Mobile's S3 not AT&T. Second, Like @passtheknowledge said, you really need to do significant research and reading here on XDA.

Please Read through this Thread. For Future Reference, all Odin Files for S3 in general are looked up by unique Keyword Root66. That thread is the right place for you to post errors or issues. If there's no 4.3 image for your phone there, you can post a request as well.
For your immediate Problem, there is a an alternate ATT StockMod Rom by @saranhai Please see this thread. Pay particular attention to the mandatory requirement of flashing a particular modem beforehand.

Can't install 4.1.1 o 4.1.2 on my Note via Odin

I moved to another country to find out that my Note 2 is carrier locked.
I googled how to unlock it and found that option of accessing ServiceMode with *#197328649# but since my Note was already OTAd to 4.4.2, this wasn't working.
I decided to try and flash 4.1.1 or 4.1.2 to it with Odin but every single time I tried, Odin gave me a Fail, stating that Nand write start - fail.
I flashed a CM11 on it to see if it can do anything (with CWM) but something went wrong and I couldn't get pass the "Galaxy Note II" screen, so I flashed 4.4.2 with Odin and it worked.
So I can flash 4.4.2. but not 4.1.1 or 4.1.2.
I'd hugely appreciate any help! Thank you

You can't flash firmware via odin which has older bootloader than yours must have the same version bootloader or newer. Samsung rules, sorry. Look if you find any custom 4.1.1 rom to flash via cwm and unlock it but be careful because 4.1.1 has sds bug and is possible to brick your device. Another way is to try to flash it via mobile odin which don't flash bootloader flashes all the rest but is dangerous for sds too. Maybe you can find at Internet any cheap unlock code also.

Is it possible to downgrade the bootloader? I can and managed to flash the Dutch version of 4.1.1 and it boots fine, but when I access ServiceMode, I receive Menu Not Exist message in Network Lock menu.
Can you link me an alive 4.1.1 ROM, since I absolutely am not able to find one.
Thanks a lot for your help!

Bootloader sorry but is not possible to downgrade, about 4.1.1 rom I haven't any link, take a look at old posts at forum if you find any. You can also try mobile odin the free version from here http://forum.xda-developers.com/showthread.php?t=1347899 you need to have root access to your phone and to download the correct addon (kernel for mobile odin) from the end of the page. You can flash with it the original 4.1.1 firmware which you have already. It flashes only the firmware without bootloader. If you haven't use it before read carefully the instructions and use it. It is absolutely safe, the only which is not safe is the firmware you trying to flash because of sds (sudden death symptom).
