[SOLVED] Unable to back up NV Data on S3 i9305 - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

I purchased an unlocked, unbranded i9305 S3 LTE and have not been able to back up the NV Data.
I tried this with it completely stock and even though I have tried both settings with DM in Qualcomm USB settings and the port is found in QPST it always says 'No Phone'.
After trying this on several computers, I then installed Clockwork Recovery Mod and Rooted the phone successfully, and still had no luck connecting with QPST with the same 'No phone' message.
I also tried using EFS Pro and the Qualcomm NV Tools, the phone says at first it is connected but the program freezes and then says the phone has disconnected. I tried unticking 'Read Phone version information' and it connects. But as soon as I try to read any data the Rx Tx indicators flash a couple of times in the app and then I get the same Phone disconnected message.
Can anyone help? I have searched here and online and found lots of similar cases but no solutions...
Thank you very much in advance.

I don't own this phone but are you sure you have a Qualcomm processor? From these 2 pages:
http://www.morecellphone.com/phones/samsung-galaxy-s-iii-gt-i9305/304
http://www.gsmarena.com/samsung_i9305_galaxy_s_iii-5001.php
it should have an exynos processor, so those qualcomm tools won't work. (think qualcomms are just some specific models)
Can't you just get into some custom recovery, adb to it from your computer (or terminal emulator) and 'dd' an image from the /efs partition out of it (needs root)?
How i did it:
Opened terminal emulator and typed "mount" to check my mounts. Looked up the one that had /efs on it. It should also say something like "/dev/block/mmcblk0p3" (this is the one on mine, use whatever you got from "mount"). Then do something like:
su
dd if=/dev/block/mmcblk0p3 of=/sdcard/efs.img
where the "/sdcard" is the directory where you want your efs image to go. Then you just need to copy the efs.img file to a safe place and you're done.
If you need to recover just do the opposite
su
dd if=/sdcard/efs.img of=/dev/block/mmcblk0p3
Careful with the "if" "of" order, and with what you type. dd is a powerful command and it's easy to screw up irreversibly if you overwrite a different partition by accident.
Another method, I've manually copied /efs file contents with root explorer to my sdcard and later to my computer and was able to use them to recover my phone (had an app wiping my /efs by accident).
This is how i did on mine and worked but i've heard those qualcomm's (if you really have one) have a different method and what i'm saying may simply not apply

Thank you for your response. Unfortunately even though it does not have a Qualcomm processor it does use this chipset for the modem I believe.
I've been following the instructions in this thread http://forum.xda-developers.com/showthread.php?t=1946915 but not having any luck. The phone is fine but it is not recognised correctly in QPST or EFS Pro....

$10 paypal donation to whomever can help me overcome the "charge your battery" issue
I desperately need to upgrade my firmware (Bell i9000m) to the new one (with the 3 button fix)
However I can't. When using KIES I only get "please fully charge your battery and try again"
DESPITE IT BEING IN THE CHARGE DOCK FOR 2 DAYS STRAIGHT
And before you start posting the "HTC fix" -- i've done it already (3 times) and nothing works.
I've tried powering down, connecting, starting up, connecting, powering down, etc. over and over.
$10 to the first person who can show me, conclusively, how to upgrade my firmware via KIES without getting the stupid "charge your battery" message
Cheers
I would try to uninstall Kies, and install latest version..
already done that (3 or 4 times at least)
I have the latest version
Try wiping the battery stats.
Either through ADB:
just open an adb shell and type the following.
mount -a
rm /data/system/batterystats.bin
Or
You can manually delete the file "batterystats.bin" stored in /data/system/ using apps like Root Explorer. Before you have to set the filesystem as "read/write".
this would seem to be a hardware rather than a software issue (i.e. i don't think it's necessarily Kies related -- Kies is up to date)

As stated above, I've tried this "fix" -- many, many times. Almost twice a day for the past week.
Nothing, i repeat, nothing has worked. I've done that "fix" a few times then left my phone in for 2 days straight and STILL it said I had to charge my battery
WTF?

Just so I can try again, maybe root explorer is better, how do I set the filesystem as "read/write" ?
Apologies I didn't know what you meant by "HTC Fix".
read/write should be an option in Root Explorer. Estrongs File Explorer also does it if you turn on the advanced root options.
Do you have an external SD card installed? Try removing that and see if Kie's works.
If that doesn't work, or you don't have one, try unmounting than remounting the internal Storage.

Not saying it is the problem, but could be... I've seen having one installed has KIES work incorrectly.
tried other USB plug / USB cable?
Firstly, have you tried rebooting your computer after installing Kies? Might fix something.
You might wish to use Odin to flash the latest Bell firmware (I think it's UGJH2 - guys, please correct me if this is wrong). Use "adb reboot download" to put the phone into download mode without needing 3BR, and flash the firmware directly.
Hey Funkadelick - I'd almost say I'm "glad" to see someone with the same problem, but I know how frustrating it is when kies won't update for this reason...
I've tried every solution suggested in this thread, and I'm still getting the problem.
Just to sum up:
- happens on multiple PCs (Win 7x64, Vista x64, XP x32)
- appears to have no relevance to what version of kies you're running
- tried several different USB cables, original Samsung included
- have tried the "reset battery stats" fix several times
- tried when the battery is nearly empty, all the way up to full. Even just after/while the "battery full" message is on the screen
It doesn't appear to be a registry setting, as the check is done several steps after the initial check for firmware version/phone ID;
I can get Kies to:
- Recognise the phone
- Start firmware update module
- Show available firmware update (with no regisrty editing or trickery)
- Start firmware update
- Tick box and click "Next" on verification screen
- Click "Next" on firmware information screen
- Download screen shows "Downloading from server... Do not remove the mobile device from your PC while downloading" for about 20 seconds, then give an error "The device to upgrade does not have sufficient battery power. Charge the battery and try again"
Thing is - I need the "official" carrier update for my phone from Kies so I can send it back for a fault with the signal. I was waiting for the official Vodafone update to come through Kies, in the hopes I could flash my phone back to an "official" stock to get it sent back.
I know there *is* a way of recovering the .tar file kies uses to flash the phone by looking in the user's "temp" folder in windows - but kies won't get far enough to download the file without a phone which will go through the entire upgrade process.
Is there anyone who's succesfully flashed the latest Vodafone UK firmware through Kies who can kindly see if the file is there and upload it to a file server, or transfer through dropbox?
I'll echo Funkadelick's $10 reward for anyone who can either trick Kies into downloading the file without a phone connected, or grab the following firmware:
PDA: I9000BUJM4
PHONE: I9000BUJM3
CSC: I9000GVODJM3
Why don't you try the update.zip fix?
Update.zip fix? Please, tell me more...
do you mean a fix for the battery stats problem, or is there some fix for this particular issue I haven't come across?
First this is the update.zip thread for fixing the 3BR without Kies and with no requirement on the battery level:
http://forum.xda-developers.com/showthread.php?t=785201
I fyou are with Bell, it appears pretty safe to use. Other branded phones have had problems. Bonus: You wont lose your setup.
Kies battery problem:
Despite the message, Kies complains about the battery when the detected voltage is too low, regardless of the charge level.
- Try with another battery
- Make sure your USB cable is connected directly to your motherboard not through a hub or the front of your computer case.
Thanks for the explanation - though it won't help my situation I'm afraid. I'm already able to use the 3-button method to flash firmware, as I've got the european I9000. My problem is that the firmware I need (in particular the I9000GVODJM3 CSC) is only available through Kies.
I've tried through all the USB ports seperately on the 3 PCs I've been using, I don't know if trying a powered USB hub might help somehow... but I don't have one to test.
I suppose I could order a new battery to ry out, keeping a spare is something I've been thinking of in any case
backup and delete from your registry HKEY_CURRENT_USER\Software\Samsung\Kies\DeviceDB
then update to something via Odin
open kies goto firmware update then close firmware update after it finds the version
restore the registry backup then go back to firmware backup and you should be able to upgrade to your correct regions firmware
PS NANDROID before

[Q] Dell Streak 7 Restore problem **Help**

Hi all.
I am hoping someone out there can help me.
I recently bought a used Dell Streak S7.
I tried to restore the DS& back to a factory out of the box state and no luck.
Tried the follwoing three
menu ->setting-> Privacy->Factory Data reset
pin hole by sd card\
Volume + and power -> 1. and 3.
I have added info for Wi-fi and everytime DS7 is turned off and turned on the wi-fi settings are lost.
I was able to root it with One Click Superoot but when i turn DS7 off and turn it off the SU dissapears.
I read http://forum.xda-developers.com/showthread.php?t=1011654 and i can't access CWM thorugh Goggle market.
The original owner account info still remains regardless of reboot and etc.....
I don't have a SD card for it and i am not sure what impact that has.
Android Version 2.2
Baseband Version 11.809.05.03.00
OEM version GLUNB1A132233
Build Number 14291
ANy information or any ideas would greatly help.
Thanks,
Dennis
Dennis,
Did you every resolve your issues?
I am having nearly the same issues as you were.
I bought a used Dell Streak that had been updated to Froyo. When I try to reset the device to factory settings to remove the original owners email address it acts like it works but each time the device boots back up all the original owners info is still there. Their wallpaper, email accounts, facebook accounts, twitter acounts, etc.
I have tried to use the Settings>Privacy>Factory Data Rest, it seems to work but doesn't clear the system all data remains.
I have tried turning off the unit and holding the volume up and power and using the restore option from there but each time it boots back with all the original owners info.
I can not get it to do a factory reset thus I can not associate my gmail account with the device.
Does anyone have a solution?
Thanks,
Frankie4life
No luck yet.
Still waiting and hoping.
Have you guys tried restoring with NVFlash? this procedure works great and helped me a bunch. http://forum.xda-developers.com/showthread.php?t=1018809&highlight=nvflash
If you are successful but your streak still wont get past the dell logo on boot, boot back into recovery (Vol+ and Power) and do a factory restore.
warning, this will erase EVERYTHING on your streak
Same thing here
I am having the same exact issue. I have tried restoring using nvflash... No luck
I have tried using the Fastboot method... No Luck
I even found an Update.pkg to try and update it using the built in recovery... No luck, It ends with an error of "Modem Error" says it completed successfully and then reboots to its previos state.
I have tried flashing the clockwork recovery via Fastboot and also.... No Luck
I am not a Noob and I have the the proper ADB and fastboot drivers installed, I am very familiar with using the android sdk and adb command from the SDK folder location.
I beleive at this point either due to an error or something the previous owner did the Streak is now "write protected" is this possible?
My biggest problem is when I root the devices using super one click it gives me root access and when launching the ADB SHELL i receive the "#" indicating that the shell has root, If I try and run ADB remount i receive and error
"c:\androidsdk\tools>adb remount
remount failed: Operation not permitted
c:\androidsdk\tools>"
this indicates to me that I cannot mount any memory from the device as read/write.
Any info would be helpful

hi, i'm going through something similar, where did you find the update.pkg? i've been looking for it everywhere, thank you
the answer i would suggest is use nvflash like navycow suggested you have 2 choices with that you can install unrooted 2.2.2 or honeycomb, search the thread for it and if you can't find it let me know i will post a link.
It seems that alot of people are having this problem I found the link for the OTA update here.
http://www.streaksmart.com/updates/page/2/
From there you can download the update.pkg manually or OTA
Make sure you don't use the O2 update because that is for the Streak released in EU. It took a little browsing but I found it in there somewhere

[Q] Download mode messed up

Preface:
I was performing a nandroid restore and then accidentally removed the battery at some point.
Situation:
Phone does not boot past black and white galaxy S screen.
Going into Clockwork Recovery, I am unable to factory reset, or start a restore because it seemingly is not able to detect any of the storage of the device....
(sample messages below):
Code:
E:unknown volume for path [/data]
E:unknown volume for path [/cache]
E:unknown volume for path [/sdcard]
E:unknown volume "/data"
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
Furthermore, I can't just re-flash in download mode because the computer refuses to detect it in windows. At first I thought it was a driver problem, because i've had difficulty with my computer detecting the phone at times, but now I suspect download mode is broken somehow (after trying to reinstall the drivers and installing kies, and various combinations therein). When the phone is plugged into a different computer ( laptop ) running linux, I get messages like these on the command line:
Code:
usb 1-1: device not accepting address 2, error -71
usb 1-1: device descriptor read/64, error -71
usb 1-1: device descriptor read/8, error -71
hub-1.0:1.0: unable to enumerate USB device on port 1
On another note assuming I can't resolve this in a more delicate manner, can someone tell me if it is possible to use a jtag programmer to flash the phone?
Would using a jig to get into download mode make a difference?
Thank you very much for your assistance.

I was trying to restore to stock JVR (rooted, no lagfix, semaphore kernel I think), from the ice cream sandwich port.
okey, i see, you might need to download android sdk and download the latest usb package or search around for the drivers for Nexus, since the usb drivers for galaxy s doesnt work with cm7/ics builds.
if you manage to make your pc recognise your phone you could check out this thread:
http://forum.xda-developers.com/showthread.php?t=1134975
btw, if you want to restore from ICS to stock gingerbread i think you will have to install a stock gingerbread ROM before you restore.
Hope this helps you!
(edit: if you find the driver or download it from SDK you can head here http://www.dkszone.net/setup-install-adb-android-debug-bridge-windows-7 to see a guide for how to set the driver manually)
Hm, Well I had already had the SDK and the drivers on my computer, but do I need to do anything special to install them? I recall previously trying the [right-click inf > Install] method, for some reason, but that didn't work

i had to manually set the drivers,
i used this thread to do it:
http://www.dkszone.net/setup-install-adb-android-debug-bridge-windows-7
Just jump straight to step #7 if you have the drivers
Upon selecting the driver, windows immediately complains:
"The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems."
Agh, And I thought this might actually work too.
EDIT:
Unknown if this is a success or not... but i've been alternating computers trying various permutations of fixes, and this time my laptop actually says the word samsung in the device manager....
EDIT2: Odin Sees it! I am going to try to flash JVR now... then retry restore from there....
P.S. I hope to god this is not related, but I actually just dropped my phone in between switching to attempt on laptop....
EDIT3: Detection, but immediate failure open attempting to flash. Then rebooted phone and now upon pressing start again it seems to be flashing.........
P.P.S: I've got to say, the most stable thing about this series of phone has got to be the bootloaders :#, Like seriously, this thing is boss.
EDIT4: Well. Managed to flash, Now I just get stock recovery with the same problem of it not finding the storage... I guess I will try flashing with repartion and a PIT?
I had to manually choose the folder where i store the Android SDK.
like c:\sdk\sdk\
it sucks when things dosent work like they should do!
So Yeah... Despite not really changing very much at all, download mode connects, and My phone now boots, Which is a lot better than where I was at previously So thanks for your help.
yw, happy i could help you!
The next mystery to solve is why Recovery is still screwed, and why I can boot my device anyway....
Hmm
So youre still getting the E:\ unknown volume *****?
Wich odin version do u use?
I had to use Ezodin last time to get it to flash,
then i flashed full stock JVH (with pda, phone & csc)
but i guess you could try to flash a stock Gingerbread bootloader too,

And i have Atached EZodin for you.

[Q] Big problem

Hello,
i had yesterday rooted my LG Optimus Black, after that was all perfect but at the evening i got a big bug.
They didn´t find my sim card. I searched for many solutions.
I have a good one with smart flash but i cant click at Erase Entire CP but i have WIndows Enabler active.
What can i do?
Hello. Just wanted to clarify. You mean that you cannot connect to your mobile network? Any other changes besides root?
Sent from my LG-P970 using xda app-developers app
only root and zeus v7 rom installed
the lock screen shows No sim card and security failure.
click twice on the button
really make sure windows enabler is on
are you on 64 bit or 32 bit?
i have win 7 64bit
after 2 clicks it isn´t activ at smartflash i try it in the next half hour but i think it had to be active to work.
Don't erase entire CP. It damages a partition that can't be recovered (Even with SFT) and a repair person might refuse warranty if they notice.
i have no warranty it was a present but i can´t use sim cards at any kind of rom its say the same.
At a german board the say you had to erase entire cp and after that change the imei to your original imei.

Still damages nvram. If warranty is not a issue then you can go ahead.
Sent from my LG-P970
Sorry, since I needed to do that last year, I'm curious about what damaging nvram implies xonar_ ? Thanks.
Sent from my LG-P970 using xda premium
what's the thing with nvram xonar?
When you wipe CP it wipes nvram partition on your phone ( or at least part of it). All data like mac address of and IMEI are stored there. This data isn't touched by reflashing with SFT. It's possible to read that data from phone to restore it since it's hardwired to the phone, but kernel 3 only reads it from nvram partition. Rmcc made changes to the kernel to make a dummy address if the mac address is zeroed out to allow people with corrupt nvram to use wifi. I don't know if the kernel then later reads it from phone self, but it could cause some problems with wifi and bluetooth.
If you tried flashing the official firmware of KU5900 (kdz or bin not the repack) and didn't change it to fits our device then it also corrupts nvram.
Its possible that ticking wipe CP only wipes the first bit of nvram where the IMEI is stored. There is two entries in nvram that contains IMEI and replacing both of them could 'repair' it then.
I made a backup of my nvram incase something like that happens.
LG R&D tool might fix this,but I'm not sure. It takes forever and I'm making the assumption it's because it does more than SFT.
Here the guide of the german board.
Here is a summary of my approach: (Before installing the SIM card process!)
1) Smart Flash tool load.
3 loading) The image of the LG P970 V20B page.
4) Smart Start Flashtool
5) Erase entire Ap select and process restart select (Previously appropriate COM port) The port will be displayed only if you have installed the drivers and the LG hidden menu of the smartphone "AP CP USB Switching" and "CP USB" selects.
5) Windows Portable load start, and enable the bottom of the icon menu with a simple click.
6) The Windows Portable you have the opportunity to shaded box "Erase entire CP" enable the Smart Flash tool.
7) You select the pre-loaded CP and Ap-bins and start the process. (Before you have to take the battery off the phone, disconnect USB cable, hold the loudspeaker key pushed up, tuck USB cable again. Then the phone is in programming mode, and you can put the battery back.
8) Now click the Smart Flash tool easy to start. After about 5 minutes the process is completed.
9) You should see the SIM error be gone.
10) Note: Since absolutely everything in this process will be deleted right, not the IMEI! This can be changed using a HyperTerminal program again. The right is under the battery.

If everything is deleted then your MC address will also go poof. It can be put back into nvram quite easily. Make a buckup of your nvram so that you can get your Mac Addresses out. (You can get them other ways aswel but I think this is easiest way.)
Code:
adb pull /dev/block/mmcblk0p11 /WHERE_YOU_WANT_IT/nv.img

Efs erased without Backup

Please put pit files for SM-G800F online... i erased efs file without make a Backup... i cant make and receive calls and i dont have network.... please any solution ??? Can i type my imei manually into phone?
Factory reset then reflash stock firmware via Odin. Should regenerate EFS.
No.. I make it but no successfull
Using the EFS of another device would be illegal as the IMEI goes with it. Are you absolutely sure you performed a factory reset from recovery, wiped cache and reflashed firmware form SamMobile? This worked on a Note 2 the last time I had this problem...
Phone info+ app show me no build date, no product code, no Hardware rev. and show me wrong imei number..... its curios.. i make varies factorys resets, hard resets and i flash via odin stock rom....
EFS PIT ??
Could you post the result of the following command in a terminal on your phone?
Code:
mount | grep efs
In the terminal i put your command... without su and with su .. .. I have busybox installed....
Partition itself seems fine then. The following should just return blank. If not, you need to wipe the partition again.
Code:
su -t ls /efs
Efs
Terminal
Till now the commands gives answer... Till now everything fine my friend?
Your imei is ok, not generic number or empty....
The IMEI should be fine if the command returns non-blank. The IMEI I saw on your previous screenshot looked like that of a demo model, which means it was generate due to the EFS partition being unreadable. If you still cannot connect you may try EFS profressional if you haven't already.(Backup current on backup tab, head over to Samsung Tools tab and in other tools select "Format EFS folder". After this flash firmware file in Odin before booting up again). Otherwise I'm afraid to say you may need to take it to a service center.
I did a tutorial for backup in two ways, search in general threads
Did a little research. Seems Samsung (or carriers) has made IMEI repair impossible for S5 and up(including all variants) without a service box. Seems like a service centre is the only option for now in the absence of a backup. Apologies.
I have the same problem with my S5 SM-G900F, IMEI NULL and i think the EFS partition was deleted without backup, more infos in the screenshots.
I dont know what to do guys, help plz.

Again, the only way to repair the EFS on newer Samsung devices is by using a certified Samsung service box, which, unfortunately, costs money. Samsung service centers will have this equipment, but will obviously charge for its usage too. If you manage to get your hands on one via other means, there are plenty of video tutorials around showing how to use it. It should only be a matter of time before a tool is designed for use on a PC, but for now, there is no other option. Sorry for your inconvenience and please ensure you use the correct subforum next time as per XDA rules.
