i messed something up on my jumper t20 somehow and now it gets stuck on loading whenever i try to load up the expresslrs lua script
laptop didnt recognize the radio initially and had a yellow triangle in device manager
- tried downloading the CP210x drivers from silicon labs but those did nothing
- tried downloading the STM32 virtual COM port driver from myST which got rid of the yellow triangle but now i get the error above
i dont think the radio settings are wrong, internal RF set to CRSF at 400k and external RF off
dont think i have the v2 / wrong model as i dont have the fan at the back either

#

usb port also works when using it as a joystick instead of the serial usb

#

so im probably not using the charging port

flashing guide is here:
https://www.expresslrs.org/quick-start/transmitters/jumper-t20-internal/#via-etx-passthrough

FOLLOW the flashing guide

#

one other thing: open the radio and make sure the wiring for the internal module is still intact and properly wired up to the mainboard of the radio

#

those connecting dots say the configurator cannot find the esp32 device

harsh zephyr Sep 10, 2024, 11:41 AM

#

ornate rivet flashing guide is here: <https://www.expresslrs.org/quick-start/transmitters/jum...

i downloaded the stm32 virtual com driver following this guide

ornate rivet Sep 10, 2024, 11:41 AM

#

the jumper t20 should be fine up to 1.87M baud rate

harsh zephyr Sep 10, 2024, 11:41 AM

#

ornate rivet one other thing: open the radio and make sure the wiring for the internal module...

so just make sure nothings come off or anything right

#

i just got into this sry

ornate rivet Sep 10, 2024, 11:42 AM

#

if you decide to open up the radio, post a photo of the internal rf module and its wiring

harsh zephyr Sep 10, 2024, 11:43 AM

#

okay

harsh zephyr Sep 13, 2024, 12:41 PM

#

do i have to take all this apart?? or is there an easier way

harsh zephyr Sep 19, 2024, 4:03 AM

#

just realised i mightve been using uart instead of etxpassthrough

#

I linked the flashing guide above..

harsh zephyr Sep 19, 2024, 4:05 AM

#

but like

#

i cant even follow the first step

#

because i cant load the lua script

#

ive followed everything afterwards

ornate rivet Sep 19, 2024, 4:06 AM

#

harsh zephyr because i cant load the lua script

your image above doesn't show which module you actually have

harsh zephyr Sep 19, 2024, 4:06 AM

#

wdym

ornate rivet Sep 19, 2024, 4:06 AM

#

the internal module is on the back shell

#

reasons why the lua script will be stuck at the loading screen:

baud rate too low for the packet rate set
baud rate too high for the module and radio's mcu/cpu
module is not connected properly to the radio mainboard or external bay pins
the model on the radio is not properly configured (CRSF is not the protocol selected)
you don't have an expressLRS module

harsh zephyr Sep 19, 2024, 4:46 AM

#

just tried to take it apart but realised i dont have any hex screwdrivers

#

ill buy one this weekend

#

thanks

harsh zephyr Sep 20, 2024, 2:52 PM

#

uh

#

i rounded one of the screws

#

and i cant open the radio anymore

#

is there a way of getting it out

#

its like really deep

#

and in a narrow hole

#

should i just get an external module

oh.. you don't have to say sorry to me.. it isn't my radio..

harsh zephyr Sep 20, 2024, 3:00 PM

#

nvm my dads somehow managed to get it out

ornate rivet Sep 20, 2024, 3:04 PM

#

use the appropriate tool for the job.. else you'd be making more work for yourself

harsh zephyr Sep 20, 2024, 3:07 PM

okay, it is the ELRS version
make sure all cables are connected properly

harsh zephyr Sep 20, 2024, 3:14 PM

dont see any loose wires

ornate rivet Sep 20, 2024, 3:15 PM

harsh zephyr

have you tried flashing with the V1 instead?

harsh zephyr Sep 20, 2024, 3:15 PM

#

in the configurator?

#

ive only tried v1 in the configurator

ornate rivet Sep 20, 2024, 3:19 PM

#

if you're following the flashing guide closely, there shouldn't be any issues

#

https://www.expresslrs.org/quick-start/transmitters/jumper-t20-internal/#via-etx-passthrough

#

1.87M baud should be set for the radio

#

Lua Script should load witth the right model set up

#

seems you've skipped a bunch of things at the beginning of the guide

#

e.g. making sure the lua script loads and that the USB-VCP is set with CLI mode

harsh zephyr Sep 20, 2024, 3:40 PM

#

wait where is that

#

i might be blind

#

this is the first step on the page

#

or do u mean in the general guide

not this one

harsh zephyr Sep 20, 2024, 3:43 PM

#

ornate rivet this part even before that

the whole issue was that i couldnt load the lua script

#

thats why ive had to do this

ornate rivet Sep 20, 2024, 3:44 PM

harsh zephyr the whole issue was that i couldnt load the lua script

what about the edgeTX version that comes even before the lua script

the radio could be v2, but the module itself could be v1, per the writing on the PCB

so i shld flash the one according to the module

harsh zephyr Sep 20, 2024, 3:48 PM

ornate rivet there's 2.10.4 now

ill update it now

ornate rivet Sep 20, 2024, 3:48 PM

it does, but not an actual one.. it's an on-board storage chip

harsh zephyr Sep 20, 2024, 4:16 PM

o

ornate rivet Sep 20, 2024, 4:16 PM

#

you can plug the usb into the t20, select usb-storage mode

#

transfer firmware binary into the firmware folder
reboot in bootloader menu and flash away

harsh zephyr Sep 20, 2024, 4:16 PM

#

okay

#

ill try again in abt 10 hours

harsh zephyr Sep 21, 2024, 2:15 AM

are the card sounds compulsory

the newest version is 2.10.3

do i download v2 or v1

cuz u said model was v2 but elrs is v1?

ornate rivet Sep 21, 2024, 2:21 AM

#

harsh zephyr cuz u said model was v2 but elrs is v1?

for EdgeTX, you have V2

#

i.e. T20 V2 on EdgeTX side

harsh zephyr Sep 21, 2024, 2:23 AM

#

its not letting me press flash bootloader

#

should i try v1

#

ornate rivet Sep 21, 2024, 2:25 AM

you do not have to flash the bootloader

#

just follow the steps already outlined

or am i supposed to follow this part

ornate rivet Sep 21, 2024, 2:27 AM

what is the trim switch

is it the little buttons inside

nvm i found it

updateed

#

do i flash it now

#

with expresslrs

ornate rivet Sep 21, 2024, 2:34 AM

#

recheck the model settings and the radio settings, in particular, the hardware settings

#

more so if you formatted your sd card (which you shouldn't have to do)

harsh zephyr Sep 21, 2024, 2:36 AM

#

just check if internal rf is on crsf 1.87m, external rf is off, adc filter is off

#

?

ornate rivet Sep 21, 2024, 2:37 AM

#

yes.. if you didn't format the sd card, then you don't have to do much.. just make sure those relevant settings are intact and correct

harsh zephyr Sep 21, 2024, 2:37 AM

#

okay

#

then now i flash?

ornate rivet Sep 21, 2024, 2:37 AM

#

yes

harsh zephyr Sep 21, 2024, 2:39 AM

#

still the same error 💀

#

should i just put it in the sd card directly
