Start with charging, on the right port
A console that doesn't respond often just has a flat battery. Plug the supplied USB-C cable into the port marked DC, on the bottom edge. The OTG port, on the other side of the headphone socket, is for accessories, not for charging. Use a 5 V mains adapter of at least 1.5 A. No mains charger is included with the console, so use a reliable adapter you already know. Avoid worn USB ports or extension leads that supply too little current.
Then be patient. A deeply discharged battery needs time before it will allow a start-up: leave the console plugged in for a good half hour without touching it, then try switching it on. If nothing changes, swap one thing at a time: first another USB-C cable, then another adapter. Also check that the plug is pushed all the way in and that the DC port is free of dust and fluff.
Power and Reset: the two buttons on the left side
The Power and Reset buttons are on the left side of the console, with the volume buttons on the right side. To switch on, press Power firmly, then give the system time. A Linux system takes a moment to start, and the screen can stay black for a few seconds before the first logo appears. Don't press repeatedly in quick succession: you could interrupt a start-up that is already under way. If you have only just plugged the console in after it ran completely flat, go back to the charging step first.
Reset restarts a frozen console, but it cuts everything off without saving: keep it for when the menu has genuinely stopped responding. Be wary of button combinations found online for forcing a shutdown or opening a special mode. They depend on the installed system and its version. Before trying one, check that it is meant for the 4-inch R36S Plus and for the system on your card.
| Symptom | Likely cause | What to try |
|---|---|---|
| No response when pressing Power | Flat battery or charging on the wrong port | Charge through the DC port with a 5 V adapter of at least 1.5 A, wait, try again |
| Black screen, battery charged | TF1-OS card missing, not seated properly or unreadable | Reinsert the card with the console off, read it on a computer without formatting it |
| Black screen after flashing | Image made for a different screen | Restore the backup or flash an image for the 720 x 720 R36S Plus |
| Menu visible but no games | TF2-GAME card wrongly formatted or folders renamed | Check the format and folders, refresh the game list |
| Lost saves | Shutdown via Reset or card removed while the console was on | Switch off from the system menu |
| Wi-Fi not found or refused | 5 GHz network or wrong password | Use a 2.4 GHz network and re-enter the password |
The system card must be readable in TF1-OS
The R36S Plus has no internal memory: it starts from the microSD card in the TF1-OS slot, on the right side. Without that card, or if it isn't pushed in properly, the screen stays black even with a fully charged battery. With the console switched off, remove the card, check that its gold contacts are clean, then push it back in fully, the right way round. Don't confuse it with the TF2-GAME slot on the left side: that one simply holds the games, not the system.
If the card is properly in place and nothing starts, it may have become unreadable. Put it in a card reader on a computer. Windows may offer to format a Linux partition it can't read: decline, otherwise the system will be erased. If the computer doesn't detect the card at all, the card is probably at fault. If it can still be read, make a full copy of it before doing anything else.
Black screen after flashing
Installed a different system and now the screen stays black? It happens, and it is rarely serious. Each system image is prepared for a specific screen. An image made for a 3.5-inch 640 x 480 console, such as the R36S, can start without showing anything on the square 720 x 720 screen of the R36S Plus. The console may well be running normally, but the screen isn't receiving what it expects. The very similar names across the R36 family make this mistake easy.
You have two options. The first: restore the backup of the TF1-OS card you made before flashing. The second: flash an image made specifically for the 4-inch 720 x 720 R36S Plus. Community images exist for this model. Flashing is always done at the owner's own risk: back up both cards beforehand, and if possible keep the original card untouched.
Missing games, lost saves or a card that won't read
If the menu appears but your games are missing, look at the TF2-GAME card. It must be formatted in a format the installed system can read; its documentation will tell you which. Files go in the folders created by the system, one per console, under their original names: a renamed folder or a file dropped in the root of the card won't be found. After adding files, refresh the game list from the menu or restart. For capacity, choose a microSD card of up to 128 GB.
Card refusing to accept files from a computer? Check the small lock switch on the SD adapter: in the locked position, the card becomes read-only. If saves disappear, first suspect an abrupt shutdown, through Reset or a flat battery. Always switch off from the system menu so that saves are properly written to the card, and never remove a card while the console is on.
Wi-Fi won't connect
Wi-Fi is built into the R36S Plus: there's no USB dongle to add, and the OTG port stays free. It works on 2.4 GHz only. If your router broadcasts a single network name for both 2.4 and 5 GHz, the connection may fail: set up a separate 2.4 GHz network in your router settings, or use a phone's mobile hotspot set to 2.4 GHz. Then re-enter the password carefully, including capital letters and special characters.
The connection is set up in the console menu, and the exact screen depends on the installed system. Once connected, and depending on the installed system, the console can fetch cover art and images for the games you already own, enable RetroAchievements, install free ports through PortMaster, run the updates offered by the system and receive files from a computer on the same network. The Wi-Fi is not for online play or streaming.
Battery: good habits, and when to contact the seller
The Li-Po battery dislikes two things: deep discharges and heat. Recharge it without waiting for the console to shut down completely. Before putting the console away for several weeks, leave it partly charged and top it up from time to time. Keep it away from sunshine behind a window, a car in summer or a nearby radiator. The battery can be replaced through the door on the back; its exact capacity, 3,000 to 3,200 mAh depending on the batch, is printed under that door. If the door starts to bulge or the console gets unusually hot while charging, unplug it and stop using it.
Contact the seller if the console stays completely unresponsive after a long charge through the DC port, with a 5 V adapter of at least 1.5 A and the original card properly in place, or if a button or port is damaged. The R36S Plus sold here is the version with the square 4-inch screen and built-in Wi-Fi. Tell us what you have already tried and the capacity printed under the battery door. Community firmware is neither supplied nor supported.
Frequently asked questions
Do I need a fast charger for the R36S Plus?
No. The label on the console says 5 V, 7.5 W: a 5 V adapter of at least 1.5 A is enough. A more powerful charger won't charge it any faster. If in doubt, go back to a simple adapter you know is reliable, with the supplied USB-C cable.
Can I use the Wi-Fi to play with a friend?
No. The built-in Wi-Fi doesn't allow online play or network multiplayer between two consoles. The R36S Plus has no Bluetooth either. Depending on the installed system, the Wi-Fi is used for cover art, RetroAchievements, PortMaster, updates and file transfers.
How do I choose the right system image for my console?
Check that the image is made specifically for the 4-inch 720 x 720 R36S Plus. The box says 'R36Plus' and the start-up screen says 'R36S Plus': it's the same device. Don't use an R36S, R36 Max or R36 Ultra image assuming it will work, and back up your cards before flashing.
