Title: DSO4254C Не загружается.
Edited by max8383 at 2022-4-22 14:10

Здравствуйте уважаемые коллеги.
На сегодня столкнулся с проблемой, что мой асцилограф, Hantek DSO4254C, перестал запускаться.
После очередного зависания, что произошло в процессе измерения, часто мигала кнопка RUN/Stop, и я его перезагрузил - выключил и включил питание.
После этого, прибор больше не загружается, показывает на экране надпись Hantek и QR-код.В сервисном меню, F2 - > F1 результата не дает, пишет Operation failed.
F3 - тоже самое.
На форуме подобные ситуации находил, путь решения перезаливка ПО (как я понял).
На сайте производителя, для контактов нашел только "service@hantek.com", проблему свою описал с указанием марки и серийного номера прибора.
Ответа никакого не получил.
По тому и решил создать тут тему, может кто то мне сможет помочь.
Жалко прибор выкидывать.

Dear Jing!

Thank You very much, indeed! This procedure has made me possible to recover oscilloscope and reset it to default settings. But what the interesting thing, it respawned with chinese display. But it is "well known" chinese characters on the display that denotes language choose and how to choose another language. So, there are only Fracias anв Deutsch language available in addition to Chinese. Unfortunately both of them not my native. I can't find exact manual how to change display and menus to English. I suppose it may be specifig firmware, but no sure. It this case shall I upgrade firmware? Or specific procedure to change language exist?

Many thanks for your usefull assistance!

Dear Jing,

Yes, after recover procedure only two languages are available. Even Chinese is not available now after first change of language. But I'm defenetely remember there were many of languages available before recover. As I can understand, it is not my own problem here is the same problem description from other customer -https://www.eediscuss.com/forum. ... &highlight=language

Dear Jing,

I have made successfully firmaware upgrade be means of file dso4kb_20211207.upk. But the language lists contains only Fracias and Deutsch. Make a note that word "Deutsch" has bright white color!!!
[attach]5344[/attach]

As shown int the picture firmware is the latest, but Same Fracias and Deutsch only in the Utility menu. Next I have performed one experiment:

1. I have recovered device according to video instruction You sent before. Device had returned back to 1.1.2(191028.0) version of firmaware, which is loaded from recovery partition.
2. Now oscilloscope has respawned with Chinese language:
[attach]5345[/attach]
But the interesing moment - caracters denoted Chinese language is not white. They are light grey. May be it means "not in official list for this region", because if I will try to change language - it will change only to Fracias or Deutsch, nothing else. Chinese language will dessapear.

3. From the chinese display I have upgraded to latest version of FW:

4. After upgrade English display appears, but in the same "strange light grey" mode. Changing of laguage make the same list consist of  Fracias and Deutsch only. So, if I on occasion press F1 in "Utility menu", I will loose English language forever and only Francias and Deutsch will remain. Another question - what about another languages which exist in initial firmare? How to return them back?
[attach]5347[/attach]

I suppose it is a bug of recovery image. Probably the possible workariond may by the following:
1. Upgrade recovery partition by means of specific file (pressing F3 in recovery menu).
2. May be do some changes from some kind of service-menu (if it exist in FW)
3. provide a patch for firmware.

It is only my guess. I hope You are more informed about inside structure of FW busy-box.
I hope for your help and very appricated for your cunsultation! Many thanks,

Alexander.
