IMEI is only 000000000000000 - Samsung Galaxy Note 20 Ultra Questions & Answers

I have tried to reset it via odin with its latest official rom along with all its BL, AP, CP, CSC. but nothing is working.
I bought it as a salvage device it had FRP on so i had to unlock it and i think it is a russian phone since it had russian CSC baseband.
Do i have to replace the logic board to solve this? can a IMEI be blocked and turned into 0? Or is there data somewhere that isnt being reset from the odin flash which i have to manually clean?

Hi mate
That is not that ease because of the multi csc firmwares read here
What phone do you have?
Try flashing android n fw and add singapore csc.
I hp was sg also XD waiting for public release
you should be able to change the CSC by booting into recovery and doing a factory reset this will set it to the default rom's csc.

Debranding without tripping KNOX

Hello,
Bought one S7 with a BIG discount at a local carrier and they also provided network unlock. The phone has a "generic" ROM but with custom carrier boot up logos and other minor things i want to revert to stock Samsung. My real question is that a friend also bought the same phone and flashed the BTU UK rom with ODIN and althought the phone flashed ok with stock ROM, KNOX was tripped and now he cant use S Health and other security related stuff.
With *#1234# i have:
AP: G930FXXU1BPH6
CP: G930FXXU1BPIN
CSC: G930FOPT1BPI1
With Phone Info i dont have multi CSC, only the one from the carrier (OPT)
Wich country ROM should i flash with ODIN to get the phone as stock Samsung and without tripping KNOX? My worries are warranty issues if KNOX is tripped…
Thanks a million!
Flashing stock does not trip KNOX, only flashing custom, so either your friend isn't telling you the whole story, or it was already tripped
You can flash any stock ROM with ODIN as many times as you want and it will never trip KNOX
BTU or XEU are both UK unbranded G930F ROMs
BTU has Oreo 8.0
XEU is still on Nougat 7.0 right now
Yeah, i talked to him on the phone 10 minutes ago. His problema was that he downloaded the firmware from SAMMOBILE and when he placed the AP in ODIN it complained about md5 something… he said that he deleted the md5 extension and the flash went forward. Then the result was KNOX tripped.
Can i flash BTU for Portugal? Can i flash directly from android 6 to 8?
Thanks.

Never heard of that happening before, anyway yes you should be able to flash BTU over portugal, as long as you use CSC and not HOME_CSC, flash all 4 parts, AP, BL, CP and CSC
And yes, 8 will flash over 6 as it replaces the whole OS, it's not an upgrade when changing CSCs
You might need to select "Re-partition" in ODIN 3.13.1 if it doesn't work normally
Make sure to use ODIN 3.13.1 for Oreo or the flash will fail
I will flash the latest android 6 with BTU CSC and then i will go further to 7 or 8 via OTA. Fingers crossed!

Why not just flash 8.0 BTU? Save a lot of time and problems that come with upgrades, anyway changing to 6.0 BTU you will still have to factory reset and use CSC so it makes no difference
Is BTU also compatible with S7 Edge?

Galaxy s7 g930p firmware guide

Hello i am new here i have some questions plz.clear my mind issue is i have galaxy s7 g930p when i dial*#1234# it shows AP, CP G930P AND CSC G930F what is this??? I want to update oreo which firmware should i use i am in pakistan and already use os marshmallow
Boot into download mode (Power + Home + Vol Down) and check what model number it says you have there.
Then download the firmware specifically for that model and nothing else.
Thanks for reply... in download mode its shows g930p and also in settings same model name and also back on phone side same but in recovery mode shows g930v
Here is some detail...
In the Downloads mode SM-G930P is displayed,
in the Phone Info also SM-G930P,
in the manufacturer "Samsung / Verizon",
product code "Not Active",
Original CSC code is empty,
CSC firmware code VZW,
active VZW firmware code,
available CSC codes are empty,
SCS country USA / HK,
Bootloader version G930PVPU4APL6,
PDA version G930PXXU1BPIA,
version CSC G930FXXU1BPIA,
radio module version G930PVPU4APL6.
Which model firmware should i download
Download mode is the only value that can't be changed by modifying the firmware, so it's your true model.
The G930P is the US Sprint S7 model running Snapdragon, so you can use any Snapdragon firmware with Odin (G930U/V/T/P) but don't attempt to flash anything Exynos as it will brick your phone (G930F/FD/W8/K)
G930U is the carrier unlocked generic firmware, so the best one to use if you don't want bloat etc.
Thank u so much can i now install latest update of g930u? in odin fill all boxes with g930u files also csc g930fxxu1bpia with g930u file?
Thank you so much sm-g930u firmware with oreo now working in my sm-g930p no any issue here thanks

I need help to identify the correct firmware for my S7 (SM-G930F)

I bought a new S7 (G930F) at ebay. When it arrived i wanted to update to the newest firmware, but i got an error notification.
I contacted Samsung and they told me to send it in.
They checked it and told me, that they are not willing to help because the phone is flashed with a wrong firmware. I bought it as a new device. This is unpleasant.
The seller doesn't answer my messages, so i thought maybe i can flash a new firmware by myself. The actual firmware is working but it is outdated. (1. August 2018)
But how can i find out which firmware is correct for this phone? How to say if it is exynos or snapdragon?
The phone information
Modellnummer: SM-930F
Seriennummer: 5AF94C0C
Buildnummer: R16NW.G930FFXXU7CRH2
Kernel: 3.18.71-14274519 [email protected] #1
Basisband: G930FFXXU7CRH2
Android 8.0.0
Samsung Experience: 9.0
I would like to flash the latest firmware and i want to use the phone in germany. Can somebody identify the correct firmware?
Thanks a lot
What does the phone say in download mode? The ROM can be modified to lie about the model and firmware, but download mode will tell you the truth.
If download mode says it's a G930F then it's Exynos, if it says G930U/V/T/A then it's Snapdragon.
If it is a G930F then good news is you can just flash whatever G930F firmware you want over top what's on it. If it's Snapdragon then you're a bit stuffed, you can't flash Exynos firmware onto Snapdragon.
For updating it if it is G930F my recommendation would be to find out the region code for your device, e.g. from here https://updato.com/firmware-archive...act=1&r=DBT,XEG,DCO,DDE,VIA,DTM,VD2&v=&rpp=15 then download the firmware using that region code with SamFirm tool https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Download Mode says SM-G930V
I'm doomed
Yep that's a common scam. If you can't return to seller the next best thing would be to flash the G930U firmware, which is the generic unlocked firmware for Snapdragon.
It won't give you the equivalent experience, but it will remove any bloat and give you a carrier unlocked phone experience.
You can use the same methods I mentioned to get your hands on the latest G930U firmware and update the device, but you may need this specific Odin version to flash G930U over G930V https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Thanks. Does TMK, TFN, TMB,... make a difference when the phone is used in germany?
Should i flash all 5 files:?:
AP
BL
CP
CSC
Home
I tried and my result is: Flashing only AP was not enough. Flashing all 5 worked fine for me. I chose TMK and even LTE is working. Thanks a lot.
Glad its working, for reference CSC and Home_CSC are both CSC files and you usually pick just one. Home_CSC doesn't do a data wipe, CSC does.
But when changing from G930V to G930U it's always safest to do the CSC wipe.

Changing CSC

Hi.
I just bought the Note 20 Ultra from may carrier and First what i wanted to do was DEBRAND. So acknowladge from Note8 i thought that, ill download firmware XEO - for my coutry flash it via ODIN and BANG.... but nope.. it didnt went as i expected, i mean flashing went great but CSC doesnt change. As i read some forums there was solution for Andorid10 but Ive got Android11. So im asking here "is there any solution" to change CSC to XEO ?
yeah the android 10 version method works still. Downgraded my note 20 Ultra 5G with android 11(1. Jan Patch) to Android 10(build No: N986BXXU1ATGI ) must be the Juli patch! Changed the csc with ChangeCSC Tool and after that flashed the newest Android 11 Firmware again via Odin (Build No: N986BXXS1CUA2)
My Device was branded on Vodafone.

I have found if you configure a couple of things first, CSC change still works during firmware flash.
1. enable OEM Unlock (in developer options)
2. disable FIND MY PHONE, & logout of Samsung AND Google accounts
3. Go into downloader mode and flash XEO or BTU FW (use CSC file not CSC_HOME)
4. Boot up device with your SIM Card installed.
5. During setup, phone will reboot and change to the correct CSC to match the firmware flashed.
Be aware thet your data partition wil be wiped so backup everything before you start.
Also, note the prduct CSC will not be changed but SIM1/SIM2/eSIM will be changed as expected.
Finally, you will get the correct OTA upgrades automatically for the flashed FW CSC (BTU in my case)
Good luck.
