Hello everybody
I bought three Lilygo T3S3 V1.1 since Aliexpress.
I flash the firmware from the web browser.
I have nothing on the Oled screen.
The blue light flashes very quickly.
The installation process completes fine, but meshtastic does not boot.
latest alpha firmware.
Do you have the same problem?
Thanks 
I believe there’s an issue with the web flasher for the S3 devices, try flashing manually using the install scripts in the firmware folder that you download.
From the script it worked.
Meshtatsic boot properly
I thank you
I have the same problem getting mine to boot.
I also have a T3S3 V1.1 board and attempted a full flash using the latest beta firmware release today v2.1.3.8c68d88.
The device appears to hit a critical error within main.cpp. Dumping the serial log while rebooting I have observed this error message right before it appears to hang:
NOTE! Recording critical error 3 at src/main.cpp:614
Here is my entire boot log:

On deeper inspection I am pretty certain the necessary fix was not contained in the release. We should probably be using at least v2.1.4.958d2cf: Fixed: Tlora-t3s3-v1 SX1262 firmware reboots continuously (#2308) (#2… · meshtastic/firmware@9008c75 · GitHub
I still see a boot loop on the latest release 2.1.4.958d2cf:

I flashed a Lilygo T3S3 V1.1 SX1262 (868/915 MHz) using the ESP32 Web installer. You hold down the boot button then switch on. This puts the unit into flash mode.
Meshtastic ver 2.1.6.5679a82 boots however I can’t set and save the region or any other settings, either via the Android app. CLI or WebUI. I’m thinking maybe the firmware does not fully support Lilygo T3S3 V1.1 SX1262 yet?
Did you do a full wipe and install? If so, can you try the install script via CLI? Flashing with the CLI | Meshtastic
Thank you. Flashing a “clean” install from the CLI worked. Settings are now saving and the unit is happily meshing. In future I should read the thread!
Steps involved.
Hold down the boot button on the T3S3, power on, release the boot button. We are now in flash mode.
From the CLI run device-install.bat -f firmware-tlora-t3s3-v1-“insert firmware version here”.bin
Wait for the memory to erase and firmware loaded.
Switch off/on the T3S3. Meshtastic will boot.
Use the WebUI or CLI to adjust settings.
Okay, thank you for confirming. I think there’s something up with the web flasher for the T3S3.
Has anyone got the Web flasher to work yet?
I used the web flasher to upgrade to 2.1.9 for the T3S3 V1.1, no problem. The issue appears to be fixed.
I tried the web flasher on a new device and it just gives a blank screen.
Flashing to 2.1.5 with the CLI worked.
Then I used the web flasher just to upgrade to 2.1. 9 and that worked like you said.
So apparently still an issue with the initial Flash.
Thanks
I bought a T3S3 a month ago, and was able to load v2.1.11 via the CLI. Tried to update today, and cannot connect by either Web Flasher or CLI. I have tried several cables, held the boot button while turning the unit on, but no luck. I can view the logs via the Web Flasher. Any advice would be appreciated.
Unfortunately, you’ll have to use CLI right now: Flashing with the CLI | Meshtastic. There’s a known issue with he web flasher that’s being worked on for a couple of devices due to a naming scheme change with PlatformIO. It should hopefully be fixed soon.
