[Q] Backup EFS folder - Galaxy S I9000 Q&A, Help & Troubleshooting

I have to ask this. I'm on Slimbean 2.5 and works like a sharm. Some day ago my friend who also has i9000 asks me, if I can upgrade his ROM from 2.3.6. My answer was - "yes, for sure". :laugh:
Now, after many hours (days) of work, I give up. I renew 2.3.6 version to my friend and return his phone. Why?
IMEI or EFS problem.
This is one of many procedure I tried:
- flash XXJVU or XWJW9 via Odin/Heimdall.
- flash Semaphore_2.7.4 kernel via O/H.
- turn off your phone. (IMPORTANT!!)
- go recovery via 3 button combo
- factory reset
- mount and storage: mount all the partitions
- flash the latest CM10.1_nightly
- reboot
- go recovery again
- factory reset + format system
- flash SB_build_X
- flash Slim_gapps or Aroma_AIO (I prefer AAIO)
- reboot system now.
But it didn't work. Not even in many similar procedures. His phone simply looses IMEI (and can't recognize SIM card) immediately after Android 4.x installation (even if I use CM9 or other ROMs). In some cases I come to Slimbean, but after some restarts, IMEI is going away and phone is unusable/boot loop.
I try to use Nitrality app to backup EFS folder and then restore it back, but it didn't help.
I also try EFS Pro, but I think they change something and program isn't the same as in many instructions.
It is interesting that if IMEI is lost and then I connect the USB cable, the phone asks me for PIN code and IMEI is back!!!! Strange. I change the battery with another one and the behavior is the same.
And idea?
Now I'm interesting what can I use to safely backup my working i9000? Or maybe help my friend to get 4.2.2 ...

[Q] Recovery mode not working - Please help!!!

Hi,
I have tried to upgrade the ROM on my Samsung Galaxy S i9000.
The upgrade was successful but the phone was not running well, so I tried to restore the previous ROM by using ROM Manager app.
For some reason the restore did not take place when the phone was rebooted.
After this, the phone will not boot.
When I press the power button, only the welcome screen comes on, but nothing happens.
I tried to enter recovery mode, by pressing volume-up+home+power, but nothing happens (the welcome screen comes on and that's about it).
Download mode is working.
When I try to connect the phone to the PC in download mode the PC recognizes it, but in other modes, the USB is not recognized.
What should I do to restore my phone to its previous state?
Is there another way to enter recovery mode?
Thanks,
Dubi
Use odin to flash another firmware to it, I have links below in my sig.
Instructions should be within the threads, but its essentially put the files in the matching names, and click repartition (this wipes the phone) and click start
Thanks for your quick reply.
I am not sure that I understand the difference between recovering the old ROM and flashing a new one, as you suggested.
If I use the Odin with the download mode, will it erase the contents of my internal sd-card as well and contact information or will this information still be available and I can use it to restore my phone (for example I used Titanium backup to backup the contents of my applications etc.)?
In other words, what are the differences between the two methods?
Thanks again,
Dubi
Odin is usually considered a fresh install, it usually deletes everything on your phone, (sometimes internal sd card, but not always). When you do flash through odin its like a factory reset so you will loose all contact info and app info etc. If you saved your backup on internal sd then you will loose that if you internal sd is wiped.
Going through recovery it depends on the rom and contents of the zip. Sometimes it will factory reset your phone, sometimes it wont. Usually it is advised to wipe if you are changing to a different rom, but as you said it was only an update and so it probably wouldn't require a wipe.
In your case yes everything will be wiped via Odin, and possibly your internal sd card will remain.
Titanium backup will allow you to restore the apps and data you have backed up.
Unless you can get back into recovery it may not be possible to save everything that was on there previously. The only way that I think may work is by using adb, and typing adb reboot recovery. If that works then you should maybe try the update again, or try another zip
Solve it? lemme know

[Q] Encryption unsuccessful

Hi,
Last week i installed the galaxy s value pack firmware XXJVU on my phone and everything went well. I then decided to install Slim ICS 2.5 and for some reason, the phone detected no network. I then decided to return to the XXJVS firmware that i had used before for other ICS ROMS that worked perfectly. This is when my troubles began.
After flashing XXJVS using odin i then installed Slim ICS 2.5. When the phone started, i got a screen asking for a pin code. Even though my sim lock is always off, i thought it required my sim card pin code. After the phone booted, i got a message saying encryption unsuccessful.
After trials and errors, i discovered that this error only comes up on ICS roms. When i use gingerbread ones, the phone is accessible but very unstable. Apps force close every now and then. This happens even with stock roms.
After flashing firmwares with odin, when the phone restarts, i now get the error below in recovery mode.
E:check_point2:sdcard/vox is not directory
E:copy_dbdata_media: Can't unmount /dbdata
Media files copy failed
E:format_volume failed to unmount "/dbdata"
Also my internal USB is read only. I cannot write/delete or even format it.
I have connected it to my PC and used tools like Eraser and nothing works. When i format it on the PC, it appears successful but as soon as i mount it again all the files reappear. This also happens when i use the phone to format.
Does anyone know of a tool or method that i can use to solve this problem. My technical skills are intermediate.

I have the exact same problem on my Sprint Galaxy Tab. My tab doesn't retain any data after a boot cause it can't write to internal SD card.
Try to get in the downloadmodus (i used the USB-JIG for that) and flash the stock 3part with repartition and pit file.
After that, i have no problems with this.
Slim ICS with no network: you have to flash a modem seperatly, its not included in the ROM (maybe since SlimICS 2.x).
greets Mr.AfK
I have tried reflashing again with re-partition. Re-partition only works for the system memory, not user memory. I am thinking of flashing the phone back to stock ROM then taking it back to the shop and claim warranty. The only problem is all my ROMS are on the internal memory and there is nothing i can do to delete them.
Did you trie The hardreset by use this Code : *2767*3855# ?
Sent from my GT-I9000 using XDA App
I've just tried that code. It resets the phone to factory setings but leaves the memory untouched. Then when the phone restarts it goes to recovery mode and I get the same error as before.

My last Suggestion is : make a Tornado wipe. Cant Link, so Google Form Damian & Tornado With a seperat Forum. This wipe clears more than normal, please read there what happend and what is To do. After the wipe you must mount the sdcard before you can do something!

Thanks Mr.AFK. I have tried tornado wipe and on the device it says the SD has been formatted but in reality nothing is changed.

[Q] Low Signal - Problems registering on Network - Tried the basic stuff

Hi: I'll go directly to the point here:
1. Was running helly bean 4.1.1 for over two weeks- No problems
2. Decided to try a ROM with KFC1 modem - no signal
3. Re-installed Helly bean - low signal, can't register on network.
4. Went a step back to ICS 4.0.4 Tiramislim - Baseband unknown showed on the About phone screen. Tried re-installing, didn't helped.
5. Went back to Gingerbread 2.3.5 with ODIN, re-partition and the other stuff - Have low signal, it took a lot of time to finally register on the network. Calls drop after about 30 seconds.
6. As phone is SIM unlocked, tried another card, no luck, it did the same. Tried mine on another phone, it works fine.
---Don't know what else to try---- Best I managed to achieve is being able to make a call while standing still on a spot. If I'm on the road, signal drops to nothing and back to half in a matter of seconds.
-- Also checked bands, and they're all active -- Provider is CLARO of PR
-- Checked carrier signal in another phone side by side with mine, and I have nothing while the other was nearly full --
What else should I do? Could it be that the phone went bad and had nothing to do with me changing the Rom?
A few months ago, I tried the KFC1 modem and had to reinstall from ODIN as the modem kept fixed and didn't changed by installing other Roms via CWM

dial *#06# ---> IMEI correct?
Or try:
1. Go to CMW
2. wipe all
3. in CWM go to "mounts&storage:
-> format /system
-> format /sdcard
-> format /data
-> format datadata
-> format /cache
-> format /boot --> it`s a little bit dangerous to format /boot, use it on your own risk
I did it two times (format /boot) after heavy problems with my SGS and it works
Important is, to flash a Rom with Odin after format /boot ...
For me it works ... it`s your own risk
After format /(all) your SGS is like from factory - without anything.
And after reflash a Rom via odin the boot-sector is rewritten (in GB-ROMs the bootloader is inclusive)
be brave and try it
Thanks! Forgot to mention that IMEI is there.
Phone is behaving a little bit better after flashing a GB XWJW5 with Bootloaders and as I couldn't find a rooted kernel, downgraded to rooted XVJU.
I know there are two different things, but in the areas where my data connection was on Edge before, are the same areas where I got no signal now. I'll check again the bands via *#*#2263#*#* and verify that everything is enabled as it was before.
If everything seems to be fine, what the hell, I'll format everything, including /boot.
UPDATE: Formatted /Boot but problem persisted. Flashed JVU GB ROM, Rooted and then went back to Helly Bean. Modem remained JVT???, althought the IMEI was there, I just deleted the folder contents and used a backup. Fixed EFS folder permissions. Rebooted and phone went back to life. So far it's working as it's supposed to. Excellent signal, no drop calls, data working fine. Wondering if re-installing the EFS folder had something to do or just a placebo effect??? But phone got signal immediately after re-installing EFS folder from a backup.

[Q] Can't solve a BootLoop on GT-N7000

Hi all
My GT-N7000 phone, running (it seems to remember) official Android 4.1.2 some days ago suddenly reset, driving me into the configuration procedure like the first time I switched on.
The following day it reset again, and went into bootloop on Samsung screen. I tried the following:
wipe cache data - no result
reset to factory data - no result
flash via Odin the N7000XXLT9_N7000ITVLT3_ITV Kernel - no result
When I went into recovery mode before reflashing kernel, I got the "can't mount /efs" error. After reflashing kernel, I installed PhilZ recoverty with Aroma, and discovered that the EFS folder is here, but it is EMPTY, and in fact I can't mount it even in PhilZ.
Another strange thing is that all my custom data are still on the telephone, despite the factory reset I have done.
I have searched a lot, but I can't find a way to solve my problem so I am asking you to help me
Thanks in advance

Any help?
The only things I found on internet are two tools that assert to rebuild your EFS nv_data.bin file (RIFF box and Zx3 box), but I don't want to spend money because the /EFS get corrupted by itself, without any attempt to flash or modding or whatever else.
I think that reflashing kernel will not solve my problem, because (I think) the information are hardware related, and not software related. If needed, I am able to manually change the file reflecting the IMEI and S/N on my cell box, but I need a generic file and some references about positions...
Please guys help me... even if you have only bad news
Thanks in advance

Was you phone rooted with a custom recovery before the issue started? Check in the clockworkmod folder in internal storage for efs backups like efs.img...

nokiamodeln91, thank you for the reply.
Unfortunately not, my phone wasn't rooted before the issue, and, strange enough, I didn't do anything particular on the device other than calling and browsing...
Now I installed PhilZ and have a complete backup, perhaps it's later

Hi, friend of mine ask for help yesterday with his N7000 and he has the same problem as yrs.
I rooted the phone to have a look at the efs folder and it was empty.
As the factorymode was in OFF, I thought of creating an imei folder with root explore, lo and behold as soon as i saved it it received an a sms message.
Iopen the folder and there were the nv.data folder there.
Baseband was restored but the imei was a generic one 00000049 with the serial number at 0000000 but the consolation was he is able to use the phone normally with all services from telco and even package data was working.
My friend was so happy that he was able to use the phone and was willing to live with it not wanting me to try any further.
So maybe you can try this to get the phine working and like my friend live with it haha.
One more thing if ut works for u save the efs folder and try n restore it.I dont have the chance to try as my friend dont want to bugger it agian.
Also if you swich off the phine u may have to do it again. Cheers
Edit: Phone was in bootloop too, I went to recovery and it cant mount efs.I did a wipe twice and it started up that was how i was able to access the efs folder after rooting it. Cheers

Thank you ndmuni,
I don't understand very well what you did; consider that my phone is in bootloop, so I am not able to read an eventyually SMS, but I can accesso to file system with Aroma tool in PhilZ recoverty tool. Have I to create a special folder under root in my N7000? With what name?
Thank you in advance
Paolo
