Good afternoon!
I'm looking for a dump for the LG PF1000U projector (chassis FM51E), (NAND Hynix H27U1G8F2CTR SPI_FLASH: MX25L8035EM2I, EPROM 24C256C).
There is no epk file available anywhere :(
This device attempts to turn on and responds to both buttons and the remote control:
It exits standby, runs the fans for 5 seconds, then spins them at 100% for another 5 seconds judging by the sound, and then goes back into standby.
The problem seems to be a corrupted NAND as it appears to me:

Sziasztok!
JCS-730C nevezetű alkatrész beazonosítása ... bd 244 tokozású valami lehet tranyó,triak tirisztor fene tudja..??
Egy inverterben van benne ami 12 voltról 220 voltot csinál...Nem tudom mi is lehet ez,és hol lehetne szerezni ilyent?? Valaki esetleg??
Köszönöm!
I have this component (you can see from the photo what has happened... the leg is broken off and the pad also) so I need another component. But I cannot find ANYTHING on the whole internet that identifies this. The marking is WZE horizontally along the component, and the number 26 at the end vertically. Has anyone got any idea what this might be? Thanks, Mart.
Sziasztok!
Rendeltem egy ilyen bluetooth modult az aliexpressről. Volt már néhány egyszerűbb bluetooth stick-em, de ennek a hangminősége nagyságrendekkel jobb mert elvileg a bluetooth 4.0 képes.
Sajnos gyári alaphelyzetben nem is látható ha rákeresek. Ki - bekapcsolásra reagál, ha bekapcsolom a led1 villog.
A programozásához valami CSR -USB-SPI programmer kellene. De úgy nézem ez egy sima SPI programozóval is működhetne. Akár egy CH341A spi programozóval is.
Mielőtt kísérletezni kezdenék, inkább kérdezek...
Nem próbálkozott valaki közületek ezzel a modullal?
Nekem csak sima BT hangszórónak kellene, a többi gomb a mikrofon és az usb nem kell.
Előre is köszönöm!
Joco
