Here is the list of Firmwares/ modems to OPO, that I know of.
Please tell me if I'm missing some and I'll add them here.
Current modem version can be checked from: Settings->About phone->Baseband version
Kitkat modem (44S): Here
Official OnePlus Firmware for Lollipop (241): Here (Current Firmware of COS 13.1 and CM13 Nightly)
Oxygen 1.0 Firmware or modem only (241): Here
Oxygen 2.1.4 Firmware (00013): Here
H2OS Firmwares:
00004: Here
00011: Here
00013: Here
H2OS v2.0 (006): Here
Firmwares/ modems you can flash in TWRP (see versions below), no need to wipe anything, just flash and reboot to system.
IF your SIM is not found, flash another Firmware, safest one to try in this case is: Official OnePlus Firmware for Lollipop (241).
What Firmware/ modem works the best for your phone, depends on your country/ carrier.
You can find out what's best for your phone from here: Settings->Battery->Click the battery graph->Mobile network signal, if you see mostly green it's good, but more red or yellow you see is bad and you should try another Firmware/ modem.
Battery consumption is related to this as well, more your phone needs to check/ change between 2G/3G/LTE (or bad or no coverage) more battery it will use.
You should use one at least one day, to get whole picture.
If you get "Trustzone error" while flashing your ROM, these are the only TWRP versions that can flash Firmwares/ modems properly:
Official (TeamWin) ONLY 2.8.6.0 and from version 3.0.0-0 upwards : Here
3.0.0-0 (or newer) Unofficial by Kumajaya: Here
3.0.0-1 (or newer) Unofficial by TugaPower Here
2.8.7.0.5 Materialised by Kumajaya: Here
TWRP you can flash within TWRP itself:
- Download file to your phone
- Reboot to recovery
- Click install
- Find the file location and click "images..." button (or it won't show .img files)
- Select file
- When asked, choose recovery and swipe to flash.
- Remember to reboot to recovery after flash and see that the version number (on the top) has been changed.
