No Network Status SM-985F - Samsung Galaxy Note 20 Ultra Questions & Answers

Hello guys,
I've got my hands on Note 20 Ultra (SM-N985F/DD) to take a look into, but for some reason, it's behaving strangely.
First of all, it's got a CSC WWB, on which I didn't find any reference at all. When I check app fo the IMEI it says it's null.
As a result, cell (both mobile data and usual carrier service) is not working.
I've already spent so many hours investigate this. I'm confused whether the issue is in the SCS, or IMEI, or whether its simply carrier locked.
Any recommendations on what this might be? Or anyone encountered the same?
No idea where I should focus my efforts on. Already reinstalled, factory reset, installing custom rom, uprooting, locking back the BL...
Thanks a lot in advance for your time and looking into it. :]

about SN R58N73T5CQY made in Vietnam 2020/04
about N985F WWB
it's the first time i see WWx CSC in a device , i don't know them but they are not full configured
have you connect your device in wifi and with a valid google account ?
if yes you can try to change the CSC with a tool and after factory reset
edit:
WWx are LDU (Live Demo Unit PAP )

Thank you very much @yakapa40 for all the information provided. I've looked through so many pages to get a clue where the "WWB" is coming from.
I've tried to change the CSC to XTC and factory reset, however, a part of WWB is still present and No Network still persists. When I get into Download mode, the "Carrier_id: WWB" is still there.
The phone still has BL Unlocked, but I guess that shouldn't affect it? The IMEI still seems to be null for some reason, even though it's there.
I'm now getting this info:

i,ve edit my post 2
i think WWx CSC are Live Demo Unit so no data and call

Thank you! I kinda suspected it might have been this thing.
Though, what's surprising is that the Cellar network was actually working there when it was bought - I could call and even had 4G+, before I flashed the Stock ROM to update from Android 11 to Android 12...
I guess that might then had to be some kind of hack before I bought it. Thanks a lot once again, I'll try to get through all the topics and see if there's anything I could do.

[Resolved] Guys looking for updating their GT-P1000 from Froyo to GingerBread:

Guys looking for updating their GT-P1000 from Froyo to GingerBread:
Just go download "Mobile Odin Pro" from some blackmarket link.
Get the firmware for Gingerbread 2.3.3 you want to install. Upload it to you tab's disk (not the external sd card).
Start Mobile Odin Pro. It will ask you to update some software extensions based on your mobiles version and then all you need to do is to search the firmware file on you phone and select it automatically.
and then flash it. That's pretty much it.
Cons: this Mobile Odin Pro currently only works for few (3/4) Samsung mobiles. GT-P1000 happens to be one of them
Remember: Try to open the zip file on you computer and make sure to update all the required files after extracting the zip file. You can always create a new zip or rar to upload to you cell.
In case of any questions feel free to contact me. ([email protected]) or PM me if they don't ban me
P.S: i am working on finding a solution to update GT-P1000 to icecreamsandwich custom. If i have the updates i will gladly share them with you. Thank you
just so you know, i have tried various gingerbread 2.3.3 updates and they have all come with few bugs.
If any one finds a perfect one, please let us know.
Various Firmware issues:
Unable to use USB to connect with PC or to be used as a charger
Text Messages not recognized
Taking too much RAM
App force close issues. (Have to install each app again)
Froyo available maps and navigation tools not available
and few other issues not at the top of my mind right now. However as i keep looking for the prefect Gingerbread update i will update accordingly. Thank you
USB Connection Issue Resolved
It turned out a hint in this post on USB connection trouble fixed my problem... "somehow" the device's USB port was set to 'modem mode' and I had to type *#7284# on the phone keypad to re-set it!
In my case UART was on modem so i set it to PDA and voila!! windows 7 had some driver updates and i had USB connection.
However i still have to resolve the USB Charging issue. Any help/ suggestion will be welcome. thank you.

how do i upload pics from my PC? cant seem to find a link
Can any one provide me a "free" download link for:
CSC: P1000OJPJJ1
Phone: P1000JXJJ1
Actually these are part of the official "Froyo 2.2" GT-P1000 in Pakistan (Carrier: Mobilink). I was having signal problems with other Gingerbread 2.3.3 roms i updated.
I want to downgrade to Froyo with "P1000JPJJ1" rom (which i have), however cant seem to find the exact CSC and Modem file.
I will also appreciate if some one can advice me on how to get the modem settings saved from an official tab and transferred to my tab.
Please correct me if i am wrong.. i order to get my signals working, i have to have the correct modem file? right combination will be:
Base Band: P1000JXJJ1
Kernal: 2.3.32.9 [email protected]#1
Build No: Froyo.JPJJ1
*#1234# would then show:
PDA: P1000JPJJ1
Phone: P1000JXJJ1 (Required)
CSC: P1000OJPJJ1 (Required)
Any help will be highly appreicated

Compressing and decompressing files
And it uses your root property that I need, such as copying or system files matching any browsing and handles all the files in cases was recounted in the phone available
- Dealing with the Android feature
Deals with the ADB and Fastboot
ADB: formate device, delete Algimaal account, delete the lock screen, recounted the work of the phone, remove your root read phone data, reboot the phone to any setting you want
fastboot: formate phone, 'usually run to the phone to boot loder, flashing a particular area such as the boot cache userdata system misc

This picture when you try flashing the phone S5263
And I've experimented with many Samsung phones
And so there is the same interface for flashing RockChip and Allwinner and LG But are under experimentation

After updating the data base

HTC One Mini (M4/P58200) locked in Bootloader

So my problem is next : My friend showed me his HTC One Mini device stucked in bootloader. I tryed factory reset, but that's just booting in bootloader again. I asked him if the battery drained out when updating, and he told me he that's kinda happend, so i said izi task, installing new firmware and will be as good as new!
Then I spended 2 long days on internet trying to fix this, btw I think I know everything about this brand now (jk, I don't know ).
I tryed all, but every time I opened a door, I crushed in many more of them. So here is what I did in chronological order :
1) Tryed to instal custom recovery so I can install Custom ROM.
BUT
{

"lightbox_next": "Next",

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Soooo next I googled this problem, and I saw that bootloader needs to be unlocked.
2) There I go. Created account on htcdev. All steps worked for me, except the last one. No pop up shows to confirm that I want tu unlock it.
BUT always is a BUT
Looks all god, isn't it? What is sad. Sad is that the phone still looks like this :
Yap, no popup screen. So saaaaaad
3) I read on some forum that I can install custom firmware if the tevice is S-OFF.
But another sad thing, I also read that the bootloader needs to be unlocked in order to get S-OFF.
My life is like this phone, locked in a loop. I try to install custom rom need to unlock. Cant unlock need to get s-off. Can't get S-OFF cause my device need 2 be unlocked.
Soooo I move forward. I found this piece of software,
but it needs the phone to have "use usb debugging " or something like this, AAAAAND OF COURSE IS NOT.
Every gate that I found had another 3 or 4 locked doors after. Please help me. Is kinda my reputation in game. I don't recive money, is my friend. Is just that's the first thing I can't repair, and that hurts. Im like the guy who knows everything and this is embarrassing.
Also I looked in Device Manager to see how does my PC recognize the phone. Before installing HTC sync was recognizing it, but said no drivers available. And showed up like "Android 1.0 device".
After I installed the drivers it looked like this.
I go even deeper and I found this :
On the first red exclamation point one, in that box from General was writen :
Code:

[FIXED] !!! S7 SM-G930F Bricked and i'm currently f***ed up with 3 screens only

Hi folks,
I was recently rooting my Samsung Galaxy S7, Model: SM-G930F, and here is the deal:
Root ok, everything fine. After that I dumbly disbled OEM and USB Debugging.
Then I tried to install "Patcher app" ( I'm ****ing hating myself right now ) and the phone froze and restarted with this annoying message: blocked by frp lock
Restarting it and putting it to charge resulted in blocking message... trying VOLUME + POWER + UP after restarting also.
THEN: I saw somewhere that I could try and restore the firmware to deal with it.
Thing is, I think I might have downloaded wrong PDA version ( I don't f***ing know how to find it without entering the phone but the tip is: It was bought in Brazil. If someone have ANY idea... ) + used CSC file instead of HOME_CSC and it ended up screwing more.
The current situation is:
The DOWNLOAD PAGE ( Odin Mode ) shows of but it doesn't load any more firmware files from ODIN and it shows that when not on Odin mode: " ! - An error has occurred while updating (...)" .
Here's what I've already tried since I'm in this situation:
1. Trying to use Smart Switch to restore
- After filling the MODEL - s/n it says that SM-G930 doesn't support initialization.
2. Trying to use KieS... same thing.
3. Trying to use on ODIN
AP: twrp-3.1.1-0-herolte.img.tar
FAILED
Also the folowing:
G930FXXU1DQD7_G930FZTO1DQD7_ZTO
G930FXXU1DQE5_G930FZTO1DQD7_ZTO
G930FXXU1APB4_G930FUUB1APB4_ARO ( random dl )
{ The first and second I know is for Nougat 7.0 as I updated the software myself before this novel }
everyone failed at writing...
I don't know what else to do. I'm literally stuck
Here are the pics of the current possible screens:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Edit:
Although it's recognized by ODIN, when I press start nothing happens on the S7 and ODIN stays like this:
Until it fails at writing:
<ID:0/003> SetupConnection..
<ID:0/003> Complete(Write) operation failed.
And trough Smart Switch:
EDIT (FINAL):
I'm relief and frustrated... I was not able to flash FW because the cable I was using was not the original.
After losing my hole weekend, it at least is Fixed / \
Installing FW went fine, then it rebooted and come back to life.
I found out about it by trying to send just the CSC file in when it returned a weird error message at Odin.
Also I uninstalled Kies, best thing, it didn't help until the end (basically, KIES process keep active backgrounded giving you incompatibility of driver or something like that, messing around Odin when you try to upload anything. Either you kill it or do what I did). BUT serious guys, cable incompatibility is the fist time I experienced myself.... Never though this day would come.
Hope to help anyone with same prob.
See ya!

Question Lenovo XiaoXin Pad Pro 2020 Global ROM Bluetooth and Wifi Mac Address is 00

Hi guys, I have the XiaoXin Pad Pro 2020 with the Global ROM installed, I noticed that the Bluetooth and Wifi Address is 00, Even with this address, Bluetooth and Wifi seems to work fine, I just want to know how to make it go back to normal. I did install the Chinese ROM (Including today but I already go back to the Global ROM since the Bluetooth on the China ROM doesn't work today) a few time with a modified QCN file
{
"lightbox_close": "Close",
"lightbox_next": "Next",

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
and the address is normal but this problem seems to be only on the Global ROM.
How did you lose it?
Usually it happens if you check reset state machine in QFIL or flash another persist image.
Did you also lose serial number and Widevine L1?
By default MAC Address should be randomly generated for each Wifi you connect to so it should not change much, for Bluetooth I am not sure.
You can find anyway info on how to restore MAC addresses and serial number here:
Tab-J706F Serial Number
I use the QUIL to flash the Chinese version to International version but at the end the serial number is found to be changed to 0123456789ABCDEF, is there anyway that I can change this to the original serial number please? Thank you.

I notice both the abnormal Wifi and Bluetooth MAC Address a few months ago after reset my device for thr 3rd or 4th time on the Global Rom that the seller flashed on my device, im not sure if the address is like that before the 3rd or 4th reset. The MAC Address is wrong but i still have L1 and my serial Number. (I reset my device via the settings)
I do have both the Stock QCN and Modified QCN Files if it's needed
I think im gonna leave it as it is for now since fixing the issue seems to be very complicated and the false address doesn't affect the experience in any way.
Hey @MrCrayon, since i was already exploring the QCN file trying to fix the MAC Address issue, i found a line in the file with the country code and i want to set it back to No Set like how it was when i got it, how can i change it and what do i change it to
@Ng Huy Viet I don't know what should be the value for No Set, probably 00.
I also don't know if changing the region directly in the QCN is going to cause some problem because normally if you change it from the interface it will trigger a factory reset so it's possibile that some initial settings are going to be different.
With all that said there are different ways to change values:
Use NV-items_reader_writer
Backup QCN file, edit it with an HEX editor and restore it
Backup fpinfo.bin (SN and PN are there I think to remember region is there too), edit it with an HEX editor and restore it
I never used any of these because I did not need to but you can check in the other thread for someone that did and get more details.
