Tutorial recuperare MediaNav la blocarea in logo
Multora sa intamplat sa se blocheze MediaNav-ul din diverse motive. Multumita lui
Djeman,
Buldo & colegii cercetand s-au gasit cateva metode de recuperare. Sincer vorbind, eu am inceput a gasi informatii de la
RGMaster3 dar cu timpul mai apoi am realizat ca, copia informatiile de peste tot cu care apoi el se intitula creator a acestora. Am incercat sa cumulez informatiile pe cat se poate si sa ofer un ajutor pe cei in dificultate cu astfel de probleme. Pana acum eu am reusit sa deblochez destule unitati astfel.
Cum deseori fisierele dar si detaliile unei metode sunt diferite de la o un tip de unitate la alta sa defalcat in doua procedura, una pentru MediaNav MN1 Standard si alta pentru MediaNav MN2 Evolution.
Aici nu discutam inca de MN3 Evolution 2.0, Media Display sau MediaNav MN4 ce ruleaza pe o platforma Linux.
Am pregatit si un tutorial in format PDF cu mai multe imagini grafice:

M-am gandit sa il divizez in 3 mesaje pentru a fi si mai usor de intretinut pe mai tarziu.

PREVENTIA
Pentru a preveni astfel de situatii se recomanda a avea
Dboot sau
Bootloader instalat in prealabil pe cand unitatea functioneaza inca bine. Astfel cu ajutorul acestora se poate intra in WinCE usor la vreme de restriste.
Definitie program Dboot
Programul dboot e un mic software ce ruleaza in timpul pornirii unitatii ce permite a restarta rapid in WinCE. Poti accesa WinCE-ul tau cand porneste MediaNav-ul glisand degetul pe logo-ul Renault sau Dacia de la dreapta la stanga, cand apare scris mic jos in stanga Dboot pe ecran. Va apare o fereastra la care trebuie sa dati Yes.
Dboot e particular pentru fiecare versiune, astfel facand upgrade/downgrade de versiune, automat el se pierde si trebuie schimbat si versiunea de Dboot in consecinta.
ATENTIE: De remarcat ca pentru versiunile 9.1.4.x nu e recomandat a se instala DBoot pentru ca poate crea neplaceri mari.
Un filmulet cu prezentarea Dboot sa gaseste aici:
Definitie program Bootloader
Este un mic programel ce:
- Detecteaza la pornire fisierul NK.bin in radacina cheii USB, in cazul blocarii MediaNavului in logo, scaneaza cheia USB cautand o imagine WinCE inainte de NAND si va incerca a o starta, daca nu gaseste va starta NAND original de memoria MediaNav-ului. Asta in cazul blocajului.
- Pentru a accesa WinCE din MediaNav, trebuie copiat NK.bin in radacina cheii USB formatate FAT32 intotdeauna, cu care se porneste ….
asteptand cateva minute bune (~10 min).
Acum mai nou Djeman a optimizat Bootloader-ul si booteaza instant, ba chiar si mai mult, poate fi aplicat teoretic pe orice versiune de firmware la categoria lui de MediaNav. Arhivele le aveti mai jos.
ATENTIE: Din testele mele am observat in cateva unitati ca nu intotdeauna bootloader-ul odata instalat face unitatea sa booteze. Deci exista si exceptii.
Un filmulet de prezentare Bootloader aveti aici:
Important pentru Dboot si Bootloader
Pentru a abilita USB-ul faceti click: Start – Programs – USB PHY On
Intotdeauna se lucreaza cu toate fisierele legate numai de o versiune, de obicei versiunea avuta daca se poate. Ma refer la faptul ca NK.bin, booter_standalone.bin, folderele Storage Card si Storage Card4 toate apartin de aceeasi versiune. Ar fi bine de avut un Backup al unitatii avute si luat de acolo de e nevoie.
