I9505 ota update help

I had my i9505 rooted via cf autoroot and instaled omega rom. After that I have unrooted and instaled stock rom from sammobile,the same one that i had when I bought my phone with the whole procedure - reset counter,changed csc,reset the phone and installed the stock rom (samsung status is official now). Now new ota rom has arrived as for september,I saw it on sammobile but when I check via phone for software update it always says that I have latest updates installed, how is that possible?? It wont let me update the phone to newer rom,why and what should I do? Thanks for help in advance.

Also when I connect my phone to kies on laptop it can recognise the phone for sync but when I want to check for software update it cannot see the software version of the phone??!!

what is your product code (csc)?
*#1234# what it says?
do you have latest version of kies?

Csc: I9505OXXBMF3,and I have the newest version of kies

Csc is telekom (TSR)

i meant by product code the region code, DBT, BTU, XEO.......
you can know it when connecting to kies, the last 3 letters XXXXX(???)
EDIT: OK
---------- Post added at 10:02 PM ---------- Previous post was at 09:54 PM ----------
does the pda is MF8? and are you sure you are now on TSR
because pda and csc and product code must match

AP and CP last three letters are MF8 and csc is MF3 when I type *#1234#. Also baseband or pda is MF8

I have booted into stock recovery now and somehow it says that csc is set to btu,I dont know how that happend because I am sure that I changed it to tsr. Is it even possible to change csc when I am not rooted??

very good, you have also to verify that you are on TSR product code
if you can not check it with kies try this code *2767*4387264636# if no,
boot into recovery and see it under the command line (in yellow)
EDIT: that is the reason....
no you must be rooted to change product code with app.
and sometimes wiping data and cache after flashing the stock firmware will do the trick

Booted to stock recovery and it says its btu,I dont know how I am 100% sure that I changed it to tsr. Is it possible now to change csc when I am not rooted or...?

There was a code something like #*272#imei or something like that or there is another way because I am not sure tjat from market samsung csc changer will work. Sorry my bad,I should double check the csc...

Ok,thanks for help,will try first to wipe data and cache. Should I wipe dalvik cache also or its not needed to?

*272*..... method does not work on Jellybean.
yes try the wipe options. (i guess there is no option for dalvik in stock recovery)

BTU references the CSC code which determines the locale settings of the phone. To change the CSC code or what I refer to as the "regional carrier settings", enter the following code:
*#272* [IMEI #] # (without spaces)
This will bring up your regional carrier settings at which point, you can select the 3 digit code which refers to the country/carrier you wish to use the device on. For a list of carrier codes in alphabetical listing, refer to the following link:

It should work without issue: As an example, press *#06# on your device to obtain your IMEI number which will be 15 digits in length from left to right.
Once obtained, you would enter *#272*(IMEI#)# so as an example: *#272#123456789123456#
This would bring up the regional carrier settings. Hope there was just a typo and this works for you.

There's essentially 3 parts to your Samsung Galaxy Note 3:
PDA, PHONE and CSC. The PDA is the firmware (software) in your device, the phone is the modem (2G/3G/4G/LTE) etc... and the CSC is the Consumer Software Customization.
The PDA is your software the phone is running and your GUI if I can put it that way. The key components of the device are the Phone and CSC. The phone is the modem of the device which communicates with the network for wireless voice and data connectivity. The CSC is the software that configures the communication between your device and carrier specific network when it comes to data speeds and network connectivity.
You should be able to use the method I suggested to change your consumer software customization (CSC). If this does not work, try this:
Boot into TWRP by powering off your device and once off, power on using Volume Up + Home Button + Power Button (all at once). When you see the Galaxy Note 3 logo, let go and it will boot into TWRP. Once in TWRP, press the corresponding buttons to data wipe/factory reset and wipe cache. Once done, press the button to reboot and try the *#272* method. If this does not work, try the following:
This software application will manually force your CSC since you've rooted your device:
Download and install the busy box application: https://play.google.com/store/apps/details?id=stericson.busybox
The above is needed for the CSC Changer App to work
Once installed, download and install CSC Changer App: http://d-h.st/IpA
Open the CSC Changer app and select “Change CSC”
This will take you directly to the available CSC codes list on your device. Please note that you will be able to see many codes only if your device’s firmware has multi-CSC
Select your desired CSC and tap on “Install” option
You device will now reboot and when it wakes up, it’ll have the new CSC
Hope this helps!

Correct! Make sure the BTU ROM is one which supports your model. Once you have made the change, follow my link regarding ROOTING etc... and hopefully you'll have completed everything successfully. If not, report back with your results and I'll try to help where possible.

Bare in mind my phone is the 16GB model.. do BTU models only come in 32GB? is this the cause of it? Any way around this?

OK, I am new to this as well but a bit confused by your post. BTU just refers to the CSC code of your device which tells it how to implement the CSC (Consumer Software Customization). Since you are unable to load a specific carrier ROM onto your device which will enable the features you want (which are currently crippled), what I suggest is for you to change the CSC code. Once this has been completed, load TWRP and wipe the device completely and also wipe the cache. Once this has been completed, it's recommended you download a ROM which supports your model but enables the crippled features you want to ensure are enabled. Once the ROM has been loaded, use the CSC program if the *#272* method does not work and for the CSC, change it to reflect the 3 digit code for the ROM you just installed. At this point, you should be operational.
Hope this helps!

I'm misunderstanding something here. BTU just refers to the CSC as I understand. To further assist, please go into your Settings | General | About Device and let me know what your Model Number and Baseband version are. At this point, I will further research and hopefully provide enough information to get you up and running.
There should be no reason your phones in an incapacitated state.
Hope this helps!

Nearly the same problem here! I wanted to change my XEO Firmware to a DBT with Odin, but after few seconds Odin will stop with a fail.

I have successfully flashed my UK BTU to HK TGY
I had the same issue with I trying to flash with odin at the beginning (1 file that included Bootloader, AP, CP,CSC ) then I have done some research at a chinese forum and discover the way around it.
I was given the link for the same TGY firmware but this time is split into 5 files (BL, AP, CP, CSC) instead of 1 whole file. I played with some setting as I still having Big Fail on Odin.
Then I tried to flash just AP,PC,CSC without BL and Viola is work
Now my Note 3 is running TGY firmware

..

i have also TGY note 3, after flashing Omega rom, my firmware became:
AP: N9005XXUBMI7
CP: N9005XXUBMI5
CSC: N9005OXXBMI4
no idea which region the rom is, but it doesn't matter about internal memory sizes (16/32/64)

OXX mean multi.csc from some European Countrys like mine. You can see the CSC working on system/csc/sales_code.dat.
But BTU is included on OXA multi.csc.
Try flash this on recovery and You have BTU by default. (For me work, but flash at Your risk and reponsability).
Link Deleted. Sorry
To validate the new CSC You must reboot by recovery and make full wipe (data + cache + dalvik) and a new configuration.
Before this make a Nandroid Backup and copy Your efs folder to Your extSdCard and to Your PC.
Think... think... better before....

[Q] SM-N910H CSC Change without Root

Hi, I have SM-910H with ACR CSC. I have tried flashing multiple Stock Roms but CSC does not changes. I have factory reset multiple times. Also I have tried below mentioned method multiple times but no avail. If anyone has been successfully change CSC on 910H without root, kindly help me out.
1. Run and configure Odin. Do NOT check “Re-Partition” and “Auto Reboot” check boxes.
2. Load the stock firmware in the PDA button.
3. Set the phone in download mode (Volume Down+Home+Power button). Then connect the phone in your computer.
4. Hit the “Start” button and then wait.
5. Once the flashing successfully completed. Do NOT let it reboot into the normal mode.
6. Reboot into recovery mode (Volume Up+Home+Power button).
7. See if it’s applying the CSC file then wait until it finishes and reboot.
8. If you do not see the CSC installation, instead choose the “Wipe data/Factory reset”. Then repeat flashing the stock firmware. You may then achieved the CSC code flashing the stock firmware on the second attempt.
10. Confirm the CSC code by using Kies 3 or by downloading Phone INFO ★Samsung★ and see if the CSC code has changed.

Thanks for the advice. I can try that. Can you point out any 910H firmware that is single CSC. Also can you tell how to check from downloaded firmware that it is whether single CSC or multi CSC.

I used to flash Singapore rom when I was facing problem like u r facing but i don't know about your model, there was a thread in note 3 forum mentioning this.

Note 3 thread for csc
http://forum.xda-developers.com/showthread.php?t=2666907

i don't mean to hijack the thread but i am on the same boat with n910f (not rooted).
I have a warranty appointment (battery drain) and wish to flash back to stock. I purchased my phone sim free from Switzerland and i am in the UK. however i tried lollipop German rom (and sadly did not record my csc, i am a noob) and have now downgraded to UK rom to test battery drain issue for a day or two. I now wish to revert back to stock. my phone id csc related fields are as below.
original csc code: BTU
firmware csc: AUT
active csc code: BTU / AUT
csc country iso: CH
which rom should i flash to and back. Also considering the german lollipop rom data has completely gone from the csc which i flashed to the UK rom afterwards will it be safe to flash to it without auto reboot and then flash back to AUT swiss rom. i'd rather not have to set up my device again . and any comments on Warranty things / recommendations i need to take care of before my appointment
thnx
*********my solution ---------
I reset to factory default , installed lollipop rom, reset to factory default, booted lollipop, reset to factory default again, flashed swiss image , reset to factory default and everything was back to stock

This shouldn't be a problem so let me help. First some questions...
1. From which carrier/country is your phone?
2. Does it have a network lock?
3. Is it the Model number SM-G950F?
4. Which files did you flash via Odin (please type the actual filenames) and with which settings in Odin?
5. If you go into Settings - About phone - Software information - Service provider software. Please tell me the first and third line there under this point.

Hi,
1. Bought from Vodafone UK
2. Removed lock by code
3 G950F
4 Sorry don't have access to my laptop now but I've
Downloaded latest btu software from sammobile
unpacked it and used as per instructions. Tried using either home_csc or the other one but no luck either
Settings tried just standard and tried pit and reformat didn't work either
5. SAOMC_SM-G950F-OXM_XEU_077
XEU/XEU/VOD
when go into recovery it's still VOD tho

You have done all you could do.
You needed to flash with normal CSC NOT with HOME_CSC to change the CSC.
Your new CSC is XEU!
It still shows XEU/XEU/VOD because VOD is the original CSC of your phone. This is new for the S8 and could not be changed! But normally you will get OTA updates for your new XEU CSC just fine! And any Vodafone-Apps should also be removed.
So everything is like on Samsung devices debranded bevore - beside that the factory CSC is hard branded inside the phone. But thats just optical. Everything else works like it is an XEU CSC.

Are you sure about that? In the past if you didnt change properly the CSC after unbranding your phone you werent getting OTA updates anymore, i've read on SamMobile you gotta use Smart Switch using the serial number of a phone you know has that CSC, but i dont know how to find one, no one answered me on here. I'm thinking of going into a store and look at the exhibition one, but im afraid it's not legal to do that.

i can see topic is here open https://eu.community.samsung.com/t5/tablets/tab-a7-update/m-p/5030111/thread-id/12475 but there is no solution to keep data ! (only menu where you can hard restore everything when you delate everything)
Thank you for your urgent help.

Boot into download mode and flash the same stock rom version you were previously on onto your tablet, just dont flash userdata. This will reflash android. Apps and settings may be cleared, but internal storage (photos, videos etc) will remain intact. Look for a guide on how to do this.

@PhotonIce can you give more infos please
when i enter power + volume up i go to this menu
what next .... how to i apply update from ADB or even how do i apply uppdate from SD card
a lot of people are waiting for step by step process to save the data

inside .. fyi

is it possible to update only android side via ODIN.... how can i do that ? Please need help

Ok, lets get into this.
First, we need to find the signed firmware files for your specific tablet. Sammobile is a well-known source for samsung stock roms. Now we need to find the model number, which is t505. Next, we need to match the PDA and android versions, which you've mentioned above. Now, the slightly hard part. We need to get the rom for the right country (csc). Your csc ins mentioned above. Notice the OXM after T505. That is the country code. You can match this up on any samsung csc key to find the country.. Now, OXM is a universal CSC code, which doesn't really help with the download. We need more information, you can usually check your csc from the about phone menu in android, but you cant really do that. So our other option is for you to send a picture of the details from download mode, the csc will be mentioned there. To enter download mode, follow this tutorial for your device:
Upon entering download mode (after pressing volume up), look for the csc and send it here. If you cannot find the CSC, just send a picture of the entire screen. Also please mention which country you got this tablet from, and which country you are in, also mention if it is on any carrier etc.
Once you provide this information, we will be able to pick the most suitable csc for your stock rom, then I will provide further instructions on how to flash the software without losing your data. Note that you may lose your apps, but you will definitely not lose your photos, videos, files etc.

Ok, so we'll be using the slovenia csc. Upon confirming the details on the sammobile download page, the pda and csc match, so we should be good to go. One thing I did notice is that in your first post you said the PDA was "T505XXU3BVB8", but in the picture of your recovery, it shows "T505XXU3BVB2". Can you confirm anything about this?

@PhotonIce it is T505XXU3BVB2

Well now we know which firmware we need to download, here's the link, you'll need to register on sammobile to download:
Download Samsung Galaxy Tab A7 LTE SM-T505 SIO Slovenia T505XXU3BVB2 firmware
Fast download latest Samsung Galaxy Tab A7 LTE firmware SM-T505 from Slovenia with T505XXU3BVB2 and Android version 11

@PhotonIce done ... next (i have ftth at home so that why is so fast)

Alright, now we'll need to install The Samsung USB Drivers, and download Odin. Here are the links:
Drivers
Odin

done

Extract the drivers zip and run the installer.
Once it's done, extract the firmware zip and post an image of the files inside the extracted folder

@PhotonIce

Ok, open odin, then connect your tablet to your pc in download mode. You should see an empty box under the word ID:COM turn blue with a COM- number.
Next, click on BL in odin, and select the file starting with BL_ from the extracted folder.
Click on CSC in odin, and select the file starting with HOME_CSC_OMC_ from the extracted folder.
Click on CP in odin, and select the file starting with CP_ from the extracted folder.
Click on AP in odin, and select the file starting with AP_ from the extracted folder
Leave userdata empty, and make sure not to use the file starting with CSC_OMC_.
Once you have done this, click on the options tab on the left of odin, then send a screenshot of the entire odin window so that I can confirm that all is good.

@PhotonIce

Alright, everything seems good. As long as you selected HOME_CSC and NOT CSC_, then you should be good. Just press the start button to begin flashing, it will take a couple of minutes. Do not power off or unplug your device during this process. Once it is done, you device will automatically reboot, so do not try to manually reboot.
Good Luck! If it worked out then post here.

ok lets try . Yes i have selected HOME_CSC !!!!!!!!
