Hello!
First I wish to thank you for your enormous, complex and useful work hacking this nice chinese scope series. People like you play an crucial rule in technologycal advance.
Second, I apologise for my poor English. (my Deutch instead is not poor; it is null

Third, I beg pardon for not searching your very big thread fully where certainly I can found a lot of what I need. I confess, it's very hard to me not get confused by the bulk of information there, although i have learned a lot following it the last days.
And at last I ask for your help and advice:
I recently bought a rebadged Hantek/Tekway (so I think) 100MHz 1GS/s 1M sample points distributed by Icel-Manaus, a maker/seller from a free-zone in my country (Brazil). It is visually identical to the Hantek DSO5102 model. It came with two PP-150 probes. On it's rear, close to the USB connector, the place for a RJ type Ethernet connector is still unpopulated and not broke open.
From its utility menu system information option I got these data:
[modêlo] DSO02102 // model
[Versão SW] 2.06.3 (120507.0) // SW version
[Versão HW] 10070x555583e9 // HW version
[Número de série] T 1G/012 008100 // serial #
[inicializações] 13 // boots
[atualizações] 0 // upgrades
[lcd front ts] 0.0.0 //
The serial number showed is the same as printed in a badge on the case back.
I have not made any upgrade or bandwidht hack yet.
I made a back-up dump (my-dump.zip) by using your tool (dst1kb_b_backup_tool.up md5sum=58bfe4b0609f795411ba2558fdd06c08 with the 0571tekway password) and can send it to you, if you please.
It boots on portuguese language and shows a custom ICEL-Manaus splash screen before start working, apart some bugs.
I can open it and take some photos of the boards. To hook to the UART port is not a problem to me also. I'm a Linux (Suse) user and have some programming skills.
My main goal is to upgrade it to a stable and bug free (or almost bug free) version of firmware. To extend its bandwidth can be a bonus if not compromise its reliability and precision/accuracy as a 100MHz scope.
So I wish to know what's the best upgrade file to use and how can I get it. I got the file dso5kb_func_dso5102b20160111.up from the Hantek site. Have you tried it?
I bought the instrument second-hand but almost without use. The maker/seller (Icel-Manaus) does not support upgrades (kind of a black-box seller

).
Thank you in advance
