router tplink dead

[Vizitator mtd]

salut,am apelat la dvs.cu speranta ca poate careva dintre voi ma puteti indruma inspre ce as mai putea face in legatura cu un router tp-link.Am un router tp-link model : TL-WR2543ND , http://www.tp-link.ro/products/details/?categoryid=1681&model=TL-WR2543ND#spec, am schimbat firmware-ul pe el in urma cu 1 an si am pus openwrt,a functionat perfect pana azi cand mi-a facut ceva figuri si m-am gandit sa-i rescriu firmware-ul, am intrat in el (prin consola pe ssh) si i-am dat

mtd -r write /tmp/original_firmware.bin firmware

cea ce inseamna rescrierea de software.Intamplator si dintr-o prostie am observat tarziu ca am stick-ul in el si i-am dat comanda,apoi am anulato repede cu "ctrl+z",am scos stiku si i-am dat restart.(stik-ul il foloseam pentru extinderea memoriei routerului,deci pe el era o parte fictiva din firmware).Acum nu mai raspunde la nici o comanda,la absolut nimic,am incercat sa intru in "recovery mode" dar nu merge,pana nici la ping , tcpdump,etc nu raspunde,bootloaderu-ul din el nu mai exista,practic routerul acum nu mai are instalat nimic in el,ca sa-l pot face trebuie instalat firmware-ul cu bootloader cea ce n-am cum pentru ca nu se poate accesa pe nici o cale.Rugamintea mea e are careva idee daca se mai poate face ceva?

Te-ai conectat fizic pe consola seriala sa vezi daca e chiar mort 100%?

nu pentru ca nu am avut Cablu USB - UART TTL 3.3V si am improvizat unu de nokia pe 5 v, insa acum am cu totul alte problema mai grave,mi-au puscat usb-uriile la laptop,cred ca mi sa dus controlleru usb de pe placa de baza, nu stiu sigur,insa am asa 3 porturi usb in total din care 2 porturi sunt usb 2.0 care sunt moarte complet iar altul usb 3.0 care e mort partial in sensul ca daca introduc un stick (modelele ce au un led in cap) se aprinde ledu-ul insa nu functioneaza. Am sa incerc zilele astea sa vad daca reusesc sa fac ceva cand voi achizitiona un cablu uart ttl.La laptop ai avea idee ce poate sa fie,deci practic mi-a facut ceva scurt la usb-uri cand am pus aiurea pinii pe router si s-a auzit in laptop un zgomot de "scurt circuit" subtire...

din cate stiu eu de la 1043nd, bootloaderul e destul de greu sa-l distrugi deoarece partitia e protejata la scriere...asta daca n-ai facut-o writeable intre timp...problema e alta, daca te-ai conectat pe serial cu cablu de 5V ai toate sansele ca, pe langa porturile USB prajite la laptop sa fi prajit si placa de baza a routerului.

ce-i de facut in continuare?!...greu de spus... electronist bun, cu rabdare, vointa si scule adecvate lucrului cu smd-uri.

placa de baza a routerului am prajito,insa din fericire faceam teste pe un router adsl zyxel,intre timp la laptop din cate am auzit e posibil sa se fi stricat southbridge-ul http://i01.i.aliimg.com/img/pb/035/494/ ... 35_594.JPG , pentru ca acum daca dau volumul la sunet la maxim,raman fara sunet pana la urmatorul restart,daca las volumul pana in 50 % sunetul nu se mai opreste.Porturiile usb au tensiune pe ele (pentru ca se aprinde ledu-ul din cap de la stick),doar ca atat face,nu-mi apare nici un mesaj de eroare nimic.Placa de baza imi vede usb-urile,doar ca sunt nefunctionale,iar din ce am inteles eu, reparatia m-ar ajunge undeva intre 350-450 ron
