Introduction

Welp, it's the OnePlus 5T. The shitphone I've seen mentioned on some notable internet fellows (like rainheaven before his disappearance & cadence).

As for how I obtained this... well, I got a 5T board somewhere around 2023, with basically zero resource (maybe a bit of spare cash, but no spare time) to see if it worked, so that was shelved for longer than I cared to remember. And it was in February 2026 (following an excess of parts from some parts order and me being selected as the Dorms' lord for the year) that I finally got to find out if it worked (which, to my pleasure, it did... except for the lost IMEI, but without a SIM card I cannot even have that as an issue). And so the research begins...

Physical features

The OP5T felt barely any larger than the 3T, perhaps thanks to its curvier back (compared to the 3(T)) making it feel thinner than it actually is.

Audio Quality

The OP5 has most of its audio modules (mono loudspeaker & headphone jack) at the bottom of the device, flanking the USB‐C port. The earpiece can also double as a second speaker by either modifying mixer_paths_tasha or downloading & applying pre-tuned file (or Magisk module?) from Go-ogle Drive.

The loudspeaker is as mediocre as it could be, with the device needing to be laid on some flat & hard surface to have any chance at sounding acceptable. And it is positioned to be very easily blocked in landscape grip. As for the earpiece, I am yet to have it be a second speaker. That said, I did have mixer_paths_tasha applied so either my earpiece was not working (therefore I forgot to find a working one) or it just isn't meant to be a second speaker. Or I needed to do further research on this.

The headphone jack quality is average, but at least its positioning won't get in the way of landscape gaming as much as the X3(N/P) would & only "costs" 1 hand in combination with the USB‐C.

Display

Not much to say, the 6.01' 18:9 OLED is about as noteworthy as it was not. Decently acceptable colors (and yes, those inky off blacks), standard refresh rate, and nonzero chance of image retention (or random super bright green/pink lines) after years of usage. And unlike its successor OP6 the whites feel more acceptable to the eye right out of the box.

Bootloader unlocking

The bootloader unlocking process is foolproof & simple : plug phone to PC, enable OEM unlocking & USB debugging in stock OS' developer options, boot to fastboot & fastboot oem unlock in fastboot. No connecting to internet unless you're missing the adb tools (and maybe the custom recovery & ROM files).

Repairability

In terms of repairability, the OP5T is almost similar for the 3(T) if it wasn't for the back shell and display cable positionings.

Custom ROM & Kernel Availability (as of 13/3)2026)

First off, custom ROMs on the 5T is... whatever. Sticking with 4.4 kernel, we get A10 RR by SirRGB (May 2023 SPL), A11 crDroid (Jan 2024 SPL), and official LineageOS, archived by timschumi (A11, May 2022 / A12L, December 2022). Of course, going by the ≥A13, we have official LineageOS (A15)... and that's about that.

As for custom kernels... nope, at least for ≤A11. Some Telegram user apparently made an allegedly KSU‐compatible 4.4 kernel, but it didn't work for me (internal issues & no KSU on ≤A11). And with APatch not patching the ≤A11 boot images and Magisk Delta being generally unreliable, I am forced to stick with Magisk ≤25.2 for any kind of root access.

Other issues

Let's start out with the bad ones:

For the debatable nitpicks :

And, finally, the nice to have ones:

Conclusion

The 5T... is not noteworthy. Sure, it is overall a better hardware compared to the OP3(T), but the available ROMs are notably less reliable. And... well... I ran out of stuff to say by the intro. Most of what I've wrote (aside from the ROM/kernel) on the 5T was mostly recycled from the 3T with a bit of adaptation. As such I can only conclude that the 5T is a boring upgrade over the 3T (maybe with the reliability put on the question mark, but the OP6(T) is the one to fuck that up).
