[Q] Restore to stock with own made cwm backup

I just bought my Gio in the Netherlands. I've rooted it and installed cwm 5.0.2.7 rfs+ext4. I made a backup with cwm so I have a backup of the stock ROM.
3 hours after I bought it I converted my rfs partition to ext4 to install CM7.2 this went well and installed cwm 5.0.2.7 ext4 only (so i can make backups of ext-sd (EXT4)).
My question is if I wanted to go back to the stock ROM how would I go about this ? I am thinking I should do it like this.
I believe I can't restore the backup I made with cwm initially of my stock ROM since I converted the phone partition to ext4. I would need to flash the stock ROM (download it online) with ODIN.
Root it and install cwm 5.0.2.7 rfs+ext4 and restore the backup I made of my stock ROM with cwm. Or is this step pointless and is the backup I made exactly the same as the stock ROM you download online (meaning there are no specific dutch modifications) ?
Tbh i'm quite happy how my phone is working now, I just want to try this so i'm confident I can go back to way it was.

You're right. Restoring a stock rom to a phone that hase ext4 filesystem partitions wont work. The Android OS wont start up. I did test it. Ik teste het
Installing a stock rom with Odin will make the internal system rfs again i did read.
I think installing cwm 5.0.2.7 rfs+ext4 even will make the file system rfs again? Not tested it. Would save 5 min. odin.
Happy testing

Ty for the quick replies.
I downloaded the ROM one that was suggested in the replies.
I had S5660XXKPE_S5660XXKPA_S5660XENKP1.rar I guess thats an older version.

And if you restore a stock rom via Odin, can you restore the CWM backup afterwards in order to regain your original settings and stuff ?
Or doesn't it work that way ?
Otherwise you could always do a full backup using Titanium of course...

I don't know I guess I will find out but if its the Dutch/Netherlands ROM you posted in the link I won't have to I guess.
I guess i'll have to use Titanium backup anyway since the backup I made with cwm is old already (or lose some data I don't have much I really want to keep now).

My 2.3.5 version is S5660XXKS2, which I got from the Android Advice tutorial, guess I don't have the newest either

Right my bad well anyway he said in a other thread its the newest dutch ROM

Code:
GT-S5660 S5660XXKS2 ## 2.3.5 2011 September S5660OXXKS2
Btw: My firmware seems newer, it's from September 2011. It's not official Kies though. It's on SamMobile Firmware Page.

I have no ideea which one is newer. U can stay on that no problem Mine is "good" in case of warranty issues and u must bring phone back to where u buyed it , because u can`t bring the phone with another firmware on it other then the one u have in your country Netherlands

Yeah, your right about the warranty, but I sim-unlocked my prepaid phone myself, so I guess I'm out of warranty anyway
Or is there an option to relock too ?

I have no ideea if u can lock it back . Maybe if u did a backup of /dev/stl5 ( EFS ) folder before u started to modify it for the unlock process and restore it, then it would be locked again, but i am not sure about this never did it

An appropriate CSC file followed by a factory reset should relock.

Without backup made PRIOR to installing Moon rom, with the "original" EFS files you can do nothing and have to stick to newer firmwares.

[Q]Files in SDcard 0 are missing

My tablet is Samsung N5120 Lte Hong Kong version. I have flashed rom by using odin but fail. Then I did it again. After that all file in SDcard 0 is missing. While I use root explo to look into it. All of them were moved to the root location and Sdcard 0 is emty and can not copy anything to it as well as to install apps in it. All the call function is lost as well, only wifi is still working. Pls. HELP.

I flashed it with Uk stock rom from sammobile and it did not come with pit file.
The point is it was disconnected accidentally while flashing. So, flashed again
with HK stock rom.

Did you try to flash 4.1.2 over 4.2.2 by any chance? They moved the sdcard files to data/media/0 instead of data/media in 4.2.2.
Anyways to best way to fix this is to back up ur sd card to computer and Odin flash the original ROM that came with your device. (LTE hong kong version)

I did but it can not be fixed. It seemed to be lost something.

Flashing 4.1.2 over 4.2.2 is generally not a good idea. It will work if you first copy your sd card to the proper place before you flash a rom. For 4.2.2 it needs to be in data/media/0 folder. For 4.1.2 it needs to be data/media. It is possible to do this with a file manager with root access.
Odin will wipe your internal storage this is normal. The data/media/0 folder is not suppose to exist for 4.1.2 so it doesn't know how to deal with it. You need to format it back to 4.1.2 standards. As far as calls not working you probably need to make sure you have the right settings for calls and data to work. Odin should reflash the modem unless something went wrong during flash.
You should be careful when flashing things with Odin. Odin has total access to your device. Especially since HK ROMs are very different from the ones from UK. Make sure you got the correct .tar.md5 for your device. Check this list: http://samsung-updates.com/device/?id=GT-N5120 This is for N5120.
Good Luck. Worse comes to worse you may needs to triangle away and send to samsung.

Do you still get IMEI in place? If not, the call function would not work. Are you in HK or UK?
As suggested by nickdollahz, you need to copy out all the important files from "root" directory. Then, factory reset and flash again. Please note that factory reset will delete all your data.
For your reference, I'm in HK and has flashed the UK 4.2.2 rom previously (now the Germany one). I retain the original modem file of HK since I'm not sure if the modem of UK is compatible with HK's.

In the dialer, type *#06#, or in setting->about device->status->IMEI, it will display the IMEI no. Is it the same as that in the box?
Please also advise your current baseband and phone version in setting->about device.

That's why the call function does not work.
Please also advice the build number (i.e. last entry in setting->about device) of your current phone.
Before you flashed to 4.2.2 UK rom, what is your HK rom version? It should be N5120ZHBMD7, N5120ZHBME1 or N5120ZHBMG3.
Which version of 4.2.2 UK rom did you flash? And which HK rom version did you flash again?
Do you have EFS backup? If so, when did you back it up?

There may be two possible cases:
1) The EFS is corrupted. If this is the case, since you do not have backup, what you can do is to reset flash counter, factory reset and bring it back to Samsung service center.
2) the EFS is not corrupted and is simply a compatibility issue. I read from i9300 forum that Samsung has changed the format of EFS since July. However, I'm not sure if this is the case for n5120. You may consider to flash the UK rom again and see if the IMEI comes back.
You may try (2) and if bad luck, you can flash back to HK rom and do (1) above.
Good luck!

I have IMEI problem with my phone. I flash 4.3 via Odin, but this version is full with bugs. After that i flash with 4.1.1 and the problems start. My IMEI became 0049.. After this flash I flash with 4.1.2 - 4.3 but the IMEI is 0049.. I have EFC folder on my PC, but i don't know how to reset her.. I have and other problem, on my screen i have square with info for my phone - PDA ,CSC,BAND,MEMORY and other.
Can you help me to fix this big problem for me..

no one can help u to solve your problem... no one also don't care about this..
this is the kind of oldest radio board on the device. latest modem & kernel only can read new radio hardware. that's why it cannot detect the IMEI correctly..

Note 2 SHV-E250S IMEI Null/Null

Hello all,
after Rooting my Note 2 SHV-E250S a long time ago I get bored with the stock firmware JB 4.3 SKT-E250SKSUEMK9. So I decided to flash a new Custom Rom.
I start reading and preparing. Backed up my data with Titanium Backup and used this for my EFS Backup: http://forum.xda-developers.com/galaxy-s3/development/efs-samsung-tool-universal-support-t2602325
It created this files: efs.img (20 MB) and efs.md5 (1KB)
so i went through and flashed this Custom Recovery(TWRP for SKT) with Odin: https://twrp.me/devices/samsunggalaxynote2t0lteskt.html
after reboot I wondered why I dont have to insert my PIN. Checked my IMEI and it says Null/Null
I tryed to Restore my EFS with the Samsung Tool and it didnt work.
Some forums talk about the .nv_data.bin in the EFS Folder. but I checked it with ES Data Explorer (root explorer is activated) and its not there.
What should I do now?
will it help if I go back to stock recovery?
I didnt found any for my device, so I would use [GT-N710x][SHV-E250*] CF-Auto-Root
http://forum.xda-developers.com/showthread.php?t=1933542
it contains
- SuperSU binary and APK
- Stock recovery
Click to expand...
Click to collapse

What I tried till now:
- http://howto.highonandroid.com/sams...extract-stock-recovery-from-samsung-firmware/
Download stock firmware MK9 and extract stock recovery. Flashed with Odin. But it stuck on recovery.img. After 10 min I restart the Phone and --> Nothing. TWRP is still there
- https://www.youtube.com/watch?v=Pai4BH3AWq8
Enterd ServiceMode with *#0011#. But its --> Empty
There is also the Method of flashing Modem. It´s mentioned several times. http://forum.xda-developers.com/showthread.php?t=2333216
I think its for the N7100 version. At least I didnt saw any post regarding the LTE version.

Alright, time for an update:
I decided to wait for Support and as you see --> Nothing
To post my question about the modem regarding compatability also faild because its in the dev forum. I need at least 10 posts to post there.
I'll keep you up to date

did you managed to fix the problem, as i got one E250S with the same problem (Unknown Baseband),
This happened after someone tried to flash the phone with N7100 firmware,
i tried to reflash the phone with it's original SKT firmware, and did flash the CP part twice, but that didn't fix the problem,
If someone have a solution for this, please post it here,
thanks in advance
