[Q][N9005] I want to... brand my phone - CSC change

I have bought unlocked N9005 from Germany. The problem is I need to flash very specific ROM related to my home network - T-Mobile PL.
I managed to debrand and upgrade my phone to N9005XXUENA6_N9005OXXENA5_N9005XXUENA2. Works fine.
But now I need to change CSC to TPL and flash N9005XXUENA7_N9005TPLENA2_N9005XXUENA2 - but direct flashing with ODIN ends with usual invalid ext4 image.
What shall I do to flash banded firmware?
PS: *#272*(my_IMEI)# does nothing. IMEI of course checked with *#06#

I9505 - Firmware region from S/N or IMEI

Is there any possible way of finding out the phone's original firmware region from the S/N or IMEI ? I have lost the box so there is no way for me to know it . Also kies keeps telling me i9505 does not support initialising even when phone is not connected and i enter the S/N. Probably its carrier branded and the update never comes through kies. I have a vague ideea it might be CNX (vodafone romania) but not sure. HALP !

Check here, but it may not function properly. Last time I tried it I got an error.

Flash with odin the firmware that your phone came with.

The stock Samsung firmware can be found here: http://www.sammobile.com/firmwares/database/SM-N9005/
March the last 4 characters of the csc and pda to the firmware. Download it, unzip it to get a tar.md5 file, flash the tar.md5 file in the PDA/AP box of Odin. I prefer Odin 3.07 for flashing back to stock.

Tried all those but no luck...
I coudnt register with the network after searching and selecting the network...
It says unable to connect try later... veryfew times it registered with very few sim cards yet no dialling tone etc.. finally comes again to the registration problem state.... any helps?

Wrong IMEI and wrong serial is that correct .
Have you restored your original backed up EFS folder ??

No hidden menu, no CSC, no LTE

Somewhere over the years I apparently lost the carrier directory in /efs, as well as the CSC data - is there any way of getting this back? I'm hoping it's at least possible by flashing back to stock but only as a last resort - I've tried a bunch of different things without success so far.
The phone started as a Rogers N900W8 and was immediately unlocked and rooted. Sometime soon thereafter a Bell 4.3 firmware was flashed (via Heimdall). I then switched from Rogers to Wind (now Freedom) - I believe this is where the hidden menu disappeared if I remember correctly - and the phone functioned just fine through all of this.
I then moved from that Bell BMC 4.3 to the Wind GLW PG1 5.0 firmware (grabbed from sammobile and flashed via Odin) thinking that the presence of the Wind SIM would trigger the firmware to switch from BMC to GLW but it doesn't seem to have worked out like that. I'm now running the LineageOS nightlies and the phone works just fine except for a lack of LTE which is what I'd like to sort out with the secret codes. Also, since switching to Wind I believe my mobile network has always been displayed as HOME.
Samsung Phone Info doesn't list any CSCs except BMC under original. In the firmware tab, it's not listing PDA or CSC version. There is no carrier directory in /efs nor are there any CSC files in the file system. Entering almost any secret code fails "Connection problem or invalid MMI code" - *#06# will display IMEI but all others I've tried don't work.
UPDATE #1:
Have been able to get the Canadian CSCs onto the device and recognizable as being present by Phone Info.
Ripped out cache.img.ext4 from the PG1 firmware and used Cache Ripper (found on XDA somewhere) via Wine on linux to create a TWRP flashable zip. Had to mount system in TWRP before flashing.
Changing CSC with Phone Info apparently does a Factory Reset and not quite ready to do that yet as more research seems to point to reverting to stock for the hidden menu.
UPDATE #2:
Flashed stock PG1 via Odin. Went into a bootloop after building Dalvik on first boot and had to reboot into the stock recovery and wipe data and system, then it booted fine. The back button stopped working (LOL Samsung) and I had to flash a random 5.0 custom kernel (idlekernel) to get it back. Flashed TWRP and SuperSU.
There is now an empty carrier directory in root but there still isn't one in /efs. Lots of information on XDA pointing to this being a prerequisite for the secret codes - turns out it's all bunk.
Secret codes work. Had some difficulties with Phone Info not letting me into the root menus to change CSC - was spitting out output from some failed scripts - and when I was just about to give up it started working. Changed CSC to GLW which prompted another factory reset, and now it shows GLW / BMC as the active CSCs. APNs were Bell's originally, which is not what I wanted, but after following the *#272*IMEI directions from this thread and another factory reset they are now Wind's. No LTE yet. Would like to get rid of the BMC CSCs altogether since this was never a Bell device.
Some more stuff changed in Phone Info: Product Name is now hltevl, Firmware's CSC Code is now BMC and CSC Country is Canada/CA. PDA and CSC version has also been populated. CSC Changer still defaults to having BMC selected and I'm still getting the Bell bloatware.
UPDATE #3:
Active CSC reverted to BMC after a couple reboots...they're all BMC now.

Attaching (the initial) Samsung Phone Info screenshots (don't see how to edit them into OP via mobile app) .

I recommend to flash a stock firmware instead of this custom rom.

Thanks for stopping by.
I flashed the stock PG1 firmware for the GLW CSC. But the device still thinks it's BMC - this probably has something to do with all the Canadian devices sharing identical hardware and firmware.
Then I used your tool to change the CSC to GLW. All of the CSCs remained BMC except for Active CSC which was BMC/GLW. After a couple reboots even that was gone and Active CSC reverted to BMC.
Do I maybe need the stock recovery for the CSC changes to stick ? I flashed TWRP 3.1.1 for root.

So your problem is to get LTE back, or get rid of BMC?

I'd like to do both if possible but I'm not going to sweat over the CSC if it's purely cosmetic - mainly concerned about the LTE.
I wouldn't be surprised if they are linked however since the carriers here operate LTE on different bands to the best of my knowledge.

So firstly try to install the stock BMC firmware to see if the LTE works?

Long story short, LTE isn't yet available in this location on this carrier on a Note3-supported band yet.
So that's that.

S7 G9350 No Cellular data after flashed the Hong Kong ROM

I have flashed the system from China to Hong Kong today using Odin 3.14.(Only the ap package with the HK pit file, and re-partition and F. Reset enabled) All of the roms are the original version. After flashed the phone, I found that the baseband information and IMEI becomes unknown, after a little search on Google, I use the original CP package to flash. The mobile signal solved, and the baseband and IMEI came back. Make phone calls is not a problem, but I cannot use cellular data. I have tried to set APN given by my telecom company but it didn’t work. But I noticed that the data selection changed from “4G/3G/2G” to “LTE/3G/2G”.
Is there any solution for my problem? Sorry for my poor English.

You should reflash with repartition disabled and if you are on android pie, use Odin 3.13 not 3.14 as it is not stable
