[HELP] with EFS pro v2.0.33/ Unable to flash custom roms

I cant flash custom roms with I927. When I do I loose baseband, IMEI etc.no network. I'm running ICS 4.0.4, I am rooted, my ICS is backed up in CWMR and so is GB stock. I want to back up my efs folder so I can try to restore it after I flash to a custom rom and see if that works, also I would like to have a copy of my efs in case I screw it up. In EFS pro v2.0.33 I can not get a list of any device partitions and my device is not listed as a Device Filter so I can not back up my efs folder. Im running busybox v1.20.2 and have enabled USB debugging. I have no clue how to create a device filter and I can not figure it out from anything I've read in the forums. Should I use an older version of EFS pro? Is there an easy way to figure out if my custom rom problem is an efs folder problem or something else?

Do a search in the EFS thread, I made one about asking for rogers root... theres thread sout there that explain how to back it up using ADB terminal ...
Theres 2 ways, one is taking the image of the mounted partition and the other is by copying and backing up all the files.
Don't use an app, they aren't specific enough for out phones.

[Q] IMEI is wiped out after each phone restart

My note 2 is less than a month old. i had a bad flashing experience after flashing MIUI Rom for my phone on the note 2 android development thread.This was my first rom flashing on the phone. I luckily backed up my EFS.img before flashing. After flashing the rom i lost my IMEI...i had another issues with the rom hence restored nandroid backup of my phone using CWM. & since then after restoring my EFS.img each time i will get my IMEI back but if i reboot my phone for any reason the IMEI is wiped out. I have tried restoring using the command from the elevated Terminal emulator & using EFS pro tool.
Still the same...each time i have to restart my phone i will lose my IMEI.
is there any way of keeping my EFS partition or IMEI intact after each reboot . I am on stock ROM but i didnt flash it back using ODIN as i mentioned earlier i restored my nandroid backup.
Any help will be greatly appreciated...Please help

it seems that the backup u created u must have left your efs in selecting while backup thus the recovery backup is not giving your imei back rather u are doing it manually so once u get it done , I would suggest to flash fresh using odin

flash the pit partition first using odin and then the stock it should solve the issue permanently if not take it to service center
http://forum.xda-developers.com/showpost.php?p=31801134&postcount=4
download pit from here and then flash the stock rom
if you dont want to take risk just go stock completely and use triangle away and get your status normal and count zero and give it to ss saying that the imei gets off. let them solve

btw...before installing stock rom via ODIN i put the phone in the download mode & as it had to restart to go into download mode the IMEI was wiped automatically as that was the issue...but i flashed stock firmware via ODIN & as the phone booted up IMEI was not there & hence i restored i using EFS pro again & i now i have checked it the IMEI stays after the phone restart...so the issue is fixed...thanks a ton for your reply & help :good::good:

note 2 (n7105 ) efs and custom rom install help

Hey guys. I installed cyanogenmod 11 yesterday on my note 2. i ran into some problems. There was no service, imei and baseband fields were blank. i couldn't dial the *#After countless afters searching xda i managed to fix it by reverting back to the stock Samsung firmware (4.3).
My question is how do i install cyanogenmod 11 and also get network service now that i have my imei and base-band back. I'm not familiar with efs backing up or what to do with it to get network service working on a customer rom.
Any help is appreciated. thanks

To do that you must be rooted and have a custom recovery.
Download and Install PHILZ recovery latest version.
Make Nandroid backup using recovery. Keep it somewhere safe.
Download doctor Ketan's Multitool zip file and install it via recovery.
Now you will see Aroma window with various options. Chose EFS BACKUP.
Exit Multitool and restart the phone.
Copy EFS backup from internal memory card to Phone (approximately 20mb size)
Now Flash any rom u like.
Press thumps up if you found this suggestion helpful.

Hello other solution is to use TWRP recovery , when you do a bakup whis this recovery you can choose what you want to keep : EFS, data, system etc... and where int SdCard or extSdCard.
I hope this can help you.

Deleted internal storage

Hi all,
I deleted the internal storage on my phone, and cant seem to flash a stock image using oden. I get a write protection error. I have custom recovery, and I am able to flash a few of the roms out there but not all. My main issue is I can not get a GPS signal lock using any rom. Any help would be appreciated. Thanks.

Do you have a nandroid backup from your custom recovery that includes the EFS and Modem backed up from current update? Example: OG5.

Unfortunately I do not have a nandroid backup, it also got deleted.

I was getting a auth error using oden because I was downgrading. Flashing the latest samsung image resolved the issue for me.

Note 2 backup IMEI/NVRAM

Hi, recently rooted my phone and tryimg to backup everything before i install a rom but when trying to back up the IMEI/NVRAM MTK droid tools gives me the errors
"ERROR : --- TotalBytesPerChunk Not Found. Set default Page/Spare=2048/64 !!! --- Unknown ROM structure, backup NOT possible! "
I've tried searching for solutions which have suggested
* Install Busybox- tried but seen no change.
* Download MTK droid tools from a different source- tried this too
* Slot in an SD card with sufficient space into the phone- i have enough space on my sd
* When prompted for Super User permissions on the phone and PC, select Ok or Grant - done.
I want to backup as much as possible before installing a new rom but not sure how to get by this issue/error. Any help would be appreciated thanks.

Any suggestions thanks? Currently I understand the error unknown rom structure occurs because the phone isnt a mtk phone of which it is and ive tried downloading mtk droid tools from a different source with the same errors occuring.
When i rooted my phone I used a method that attempted to install cwm but when I try to boot into it the samsung logo just jumps around the screen. Would this have anything to do with the errors?
Sorry for the amount of questions.

the most important is EFS backup, which can be done with apk from play store. Other things you can backup with titanium backup, then flash custom recovery i.e. TWRP and do full backup in recovery. That's all you need. everything else you can restore with stock rom

Thanks for your reply. I just backed up the EFS using EFS professional using a tutorial I read on here. Also used titanium backup aswell. What method would you recommend flashing TWRP or CWM? Would flashing any of those interfere with the currently attempted installation of CWM that wont boot?

flash TWRP for your model i.e. N7100, N7105, etc. using Odin 3.10.7. Do not repartition and your phone would be ok. There are guides and even movies on youtube how to use Odin
