Hardening Cellular Basebands in Android
Hey, that looks really cool. I've been wanting to mess around with this stuff on PinePhone, which is in a unique position here since there are third-party images for the baseband which are mostly open source[1].
I've been especially interested in trying to reverse engineer what's going on with Google Fi on Android, but it is definitely a bit over my head, given that until recently I didn't even really know what an AT command was :) I'm guessing since it's Google the carrier stuff is mostly for fallback and all of the actually interesting stuff is done using protobufs over a data connection. (Fi is also interesting because you can make phone calls on the web over WebRTC. I wonder if that's some kind of gateway to SIP, or what.)

Chinese Cellular IoT Radio Modules Pose an Alarming US National Security Risk
Ironically modules made by Quectel are GPL compliant (https://www.quectel.com/quectel-open-source) and you can build custom firmwares for them (https://github.com/the-modem-distro/pinephone_modem_sdk) to strip out any OTA logic.
Fibocom, on the other hand, not so much.

This happens more than I'd like to admit.
I have a PinePhone Pro, and I'm trying to figure out a reasonable way to get more than one half of ten minutes of battery life out of it, while still receiving notifications. I figure the best route to go will be to create a service that holds ports open, while the CPU is completely asleep, and either run it on the modem's processor or, as an possibility for the PinePhone Pro, but not the original Pinephone, run it on the m0 core used for power management.

Pinephone, Pinephone Pro SW Maturity?
At this moment, Mobian on the PPP with the Modem SDK ( https://github.com/the-modem-distro/pinephone_modem_sdk/releases ) and a few tweaks to the sound, the phone is great, the power is managed well, and the camera is usable. So I vote for Mobian Phosh as the current best. None of the OSs available are entirely stable on updates, so you still need to be careful.

LTE-Module for Pinebook Pro: Recommendations?
I use this one with my Steam Deck. It uses the quectel eg25, same as pinephone, and can can be used with the fancy custom firmware.

Please help
keep and eye out for this issue: https://github.com/greatscottgadgets/hackrf/issues/668

I have seen comments and github issues about HackRFs being damaged by high power transmissions. I live 500-600 meters from an airport, should I be worried?
I have read about this issue on github (have been some reddit posts over the years as well), originally in #541 which has now culminated in an ongoing investigation #974.

Which SDR should I rather buy?
However, unlike your sensitivity issues, i dont get any birdies. i have a TCXO though. (https://github.com/greatscottgadgets/hackrf/issues/216). it seems its related to clock drift calibration without one. However this is something most SDR's suffer from, as a cost saving measure. Most RTL_SDR's suffer from this as well ("rtl sdr blog v3" comes with a stable TCXO, resolving the issue.).

External LNA and broken TX
I assume this is the case since I found a GitHub issue talking about blown TX: https://github.com/greatscottgadgets/hackrf/issues/1051 And I followed the recommendation of using hackrf_transfer -c with both -a 0 and -a 1. With a separate RTL SDR tuned to the output frequency I can see a very low power CW signal with -a 0. With -a 1 there is no output. This seems to match the results in the issue.

Samsung phone
If you're talking about building attachments to work with a phone, you're almost all the way there to a standalone device anyway. You might want to look into HackRF and pwnagotchi for inspiration.

Is there any software for rtl sdr that can read signal and emulate it, for windows or Linux? PLEASE HELP!
If you get a HackRF there's a utility called hackrf_transfer which can record a block of spectrum and then play it back.
What are some alternatives?
