I'm having a problem with the new version (deviation-t8sg-v5.0.0-9864d0d) is making the display look dark and I can not change it can someone help me please could I send a new version or one that works (This email address is being protected from spambots. You need JavaScript enabled to view it.)

It took some effort to even get it to formatted, but it finally did. Uploaded the firmware again and looks like it worked. Thanks.

It's frequent case with IR8M. Try format transmitter USB drive and copy filesystem from firmware archive. Use "Safely Remove Hardware" after writing filesystem.

Hello,
I am hoping someone can help me.
I have had this radio about 3 months and everything was working with deviation ir8m-v5.x.x-2018-01-31.
Now when I try to turn it on all I get is a USB icon on the screen. and the day before it workd fine,
Connecting it to windows 10( It sees it as a usb drive but then wont open anything)
I download deviation ir8m-v5.x.x-2018-03-25. and flacht it.
I checked if button ENT was stuck with a multimeter(it,s not)
Battery,s are oke.
But now i don,t see it any moor.
If anyone can help I would greatly appreciate it.

Hello, to answer at Mchaves, I just received this Monday my Ir8m (purchase on Ebay delayed 7 days witch some problem's quality ...). In the end it's a "V2", good neutral with the gimbals and immediate power on-off.
I was able to update the firmware with the version of 2018-03-25 and install some models (E010, F36, Vtail, ...). I'm running in mode 1 and everything works fine.
Thank you for your work and the help provided by your forum.

This person have tested the second version

Thank you. first version had several hardware problems, so I would like to know if someone has already received the V2 or if I am going to be a guinea pig, kkk

I have not any IR8M, so can't say anything. But I think firmware will work for both version.

Banggood send to me IR8M V2, its ok? Gimbals ok? What do you say?!

tks

See previous message with IR8M build.

Since iRangeX iRX-IR8M (t8sg-v5.x.x-2017-09-19) is somewhat different from Jumper T8SG I will place here the builds for iRangeX iRX-IR8M.


Changes:
* Fix Corona protocol, from hexfet

Hi skrat14, Thanks for the board image, please take a read through what aMax has explained in a previous post as this problem has occurred across a number of TX brands. You can think of the Devo7e very much the same as the iR8M and his fix could work with your TX. I'm unavailable for a couple of days working on technical issues prior to a video shoot for a new documentary. I am also waiting for feedback through Banggood from the TX manufacturer. Regards, Stefan

I may have an easy method that might negate the need for Linux (mkdosfs) to achieve the same fix. I can't say for definite until I check it out under windows. However, the film crew I'm working with are heading out to the US on Monday so my weekend is a busy one.

Hi aMax, Firstly thank you for all the information the Time and the effort which is very much appreciated. This looks likely to help those that have this problem. Regards, Stefan

Hi pictures of my base

There are more than two cases where this is reported, e.g. iR8M , Jumper and Devo7e, too much for my liking.

Not so easy to explain, you switch the transmitter off and the boot time its shows only the USB sign....my own
experience. ( firmware version was 2018-24-01)

The PC found the Devo in file mode but did not show anything and formating the drive ended up with an error
Under Linux the drive was found, but no access.....
Gparted showed two 1MB section for the 2MB file space, and only the last one could be accessed.
... so no avail.

With the Walkera defusetool I uprade a 1.87MB backupfile which I had saved on 2014 and the Walkera Devention firmware worked and all model files were ok.
This led my to the conclusion that the serial flash was ok. I tested this several times with no errors.

In the end I managed to rebuild & format the drive with Linux (mkdosfs) and thereafter it was accepted on Windows again.
In addition I reinstalled the genuine Windows USB driver.
Deviation was back.

Hi aMax, In both reported cases here where the TX is loading in USB mode there would be access to the storage area as a drive. This drive can be formatted as many times as you like with no effect so I guess you must be referring to the file area where this TX boots from? If you can please detail how you fixed this problem so as to help speed up a fix for these guys. Regards, Stefan

Wrong usb file driver and/or no valid MSDos flag at the file space....
I had the same issue some weeks ago on my 7e.

He should try to access the file area with a Linux live system (CD/DVD/USB stick), just for a test.
There is nothing to reset.

This is a long shot but I'm going to try and contact the manufacturer directly to see if there is a way to perhaps force this TX into "DFU mode" or reset this TX completely. I think this is likely to be a long drawn out process so no promises, but I will try hard to get some answers.
