content: Dear friends,I am new here, just learned about this blog a few hours ago. I have an OWON SDS71021211874 and I am happy with it, for me basic noob researcher it was fine. The problem is I tried to update its firmware and things didnt work out well... It runs, but the characters are messed up, the help page and menus are unreadable. How could I some this? Could any of you please share a light? Please!

content: Perhaps you have inadvertently changed the display language.There is at least one Youtube video showing how to change the language.

content: Thank you very much for your replies. The sad part is, it's not chinese characters, it's just a bunch of dots forming a square pattern next to the decimal values. If I touch the HELP key, it is full of "screen polution" not any type of language from us humans... I will take a picture to show you exactly what I mean by that... Thank you again for your reply! I hope I can get my scope back into working condition, because I am a researcher who works on volunteers with spinal cord injuries (paraplegic and tetraplegic patients) and without a working scope I have to cancel all the agenda. This is very sad for me.

content: Owon has too many firmware variants for the same scope. I guess there's different hardware inside the same models. Did you get the firmware specifically for your model SDS71021211?http://www.owon.com.hk/support_Firmware_Upgrade_list4

content: I downloaded the version 3.4 of the firmware, it looked like the right one for my scope, but maybe it wasn't. I think I might have used this one here: SDS7102UP3.4http://files.owon.com.cn/software/upgrade/sds_upgrade_3.2_3.3_3.4.rarbecause if extract the RAR file, the is a PDF file where it says my scope is one of the compatible ones... PLEASE HELP! Sorry for being such a dummie and noob
