Bootloader and Modem - Samsung Galaxy S7 Questions and Answers

Can I only flash BT and CP on Odin??
Must BT match with my current AP?
I want to install a custom Rom and it precises I need to have the latest version of BT and CP

Depends on the ROM, most use Aroma installer and have the option to update the bootloader and modem during their install. SuperMan ROM for example will update it for you, even though the forums page says update BL and CP first.
If the ROM is the same android version that you're on e.g. it's a Nougat ROM and you're already on Nougat, then you can just flash the ROM and do BL and CP via Odin afterwards.
But if you're going from MM to Nougat and the ROM doesn't update the bootloader and modem for you, then I'd recommend a full stock Odin flash to Nougat first (CP, BL, CSC, AP) then flash the ROM after.

In Odin 3.10.6, which option do you select to flash TWRP?
I'm assuming BL is for bootloader, CP is for modem - what do you use for the recovery? AP, CSC, or UMS
I don't want to select the wrong thing and brick my phone.
Choose AP

no signal after android 9 update g955f

hi guys, im having this problem, ive updated my s8+ using odin and official firm, as i have problems when update from 7 to 8 i've flash BL with AP file. So, it booted up and no signal... any idea how to fix it? i havent try flashing BL alone again...
Flash all the images (BL, AP, CP and CSC) to do complete upgrade. CP is the modem firmware. Because you did not flash this part, the newer android firmware is not able to communicate with the modem as it expects the modem to have the newer FW.

Can I flash modem only with Odin?

Can I flash only the CP file (from original Samsung S8 pie firmware) with Odin (without BL, CSC, AP)?
Just want to update the modem only without losing everything on the phone.

Yes, what you are trying to do is frequently done by Samsung users. You can extract the modem from the firmware and convert it into an Odin flashable .tar.md5 then flash it via Odin in the AP slot.

You can get it in samfw.com . Download the latest rom for your device. Download odin tool. Unzip the rom for your device, you will see four file ap, bl, csc, cp(ignore home csc) put each of those files in odin, then reboot your phone download mode, then install samsung usb driver, and the connect your phone to your pc, and then click start. after that you can install orangefox recovery for your phone(twrp is outdated for this phone). Also most roms for this device above android 9 are treble only(except lineage 18.1), so install project spaget x from twrp and then you can flash any rom you want.

Will my device experience bootloop because the csc is not my home csc for this phone, i need reassurance, and is it possible that i only flash the BL, i'm going to install a custom rom anyway?

its very unlikely that it would bootloop, but it might boot loop if you install only the BL
