[PROBLEMA] ZE550ML bloccato in fastboot mode

[BAndroidiano]

Salve a tutti,
volevo tornare al firmware stock del mio zenfone 2 ze550ml, in quanto con gli ultimi aggiornamenti avevo un battery drain impressionate(durata massima 10 ore con un ora di schermo). Stavo seguendo questa guida

http://forum.hdblog.it/index.php?/topic/46249-ripristinare-fimrware-originale-zenfone-2-ze551ml/

quando, dopo questi 3 passaggi:
fastboot flash recovery recovery.img
fastboot flash fastboot droidboot.img
fastboot flash boot boot.img

dovevo entrare in recovery mode, ma invece di entrare in recovery mode, qualsiasi cosa io faccia, mi ritorna in fastboot mode, sono disperato!

La recovery l'ho scaricata da qui:

Non capisco il perchè, dopo dovevo solo flashare il firmware.
Cosa ho sbagliato?

Premetto che entra in fastboot mode con scritto fastboot CMD waiting.... (e mi da bootloader version - unknown)

Ciao a tutti,
ho risolto! Ho seguito la parte flashing firmware without AFT di un thread su XDA.

Ecco qui :
Flashing Firmware Without AFT:

For this you need two things first is adb tool and second is raw firmware file both links are provided here under:

Fastboot and adb tool: ( includes setup as well as independent files ) latest version updated

https://drive.google....GVuT0cwRlp2UG8


Raw firmware ( you can use any earlier downloaded RAW firmware file)
ZE551ML: https://drive.google....2x1SHg2UUlsT0U ( Link updated to google drive and latest raw firmware 2.20.40.194)

ZE550ML: https://drive.google....TBDaXZOYUNBdHM

Now very first of all, rename .raw firmware file to .zip file and extract all files from it.. now place all files in adb and fastboot folder. ( Note: to extract raw file to avoid extension issue please give firmware file a complete new name ie: "user.zip"or anything you like


now in folder ( where you placed files from raw firmware and adb and fastboot tool folder) at empty place anywhere in folder hold Shift on computer keyboard and right click with mouse. Now click open command window here.

perform the following commands

1. fastboot devices ( see if it is recognized: else plug out usb and plugin again)
2. fastboot oem erase_osip_header
3. fastboot oem erase_token
4. fastboot oem start_partitioning
5. fastboot flash /tmp/partition.tbl partition.tbl
6. fastboot oem partition /tmp/partition.tbl
7. fastboot erase system
8. fastboot erase cache
9. fastboot erase data
10. fastboot erase APD
11. fastboot erase ADF
12. fastboot oem wipe splashscreen
13. fastboot oem stop_partitioning
14. fastboot flash fastboot droidboot_sign.bin
15. fastboot flash token PROD_BOM_Full.bin
16. fastboot flash ifwi ifwi-prod.bin
17. fastboot flash splashscreen splash_sign.bin
18. fastboot flash boot boot_sign.bin
19. fastboot flash recovery recovery_sign.bin
20. fastboot flash APD APD.img
21. fastboot flash system system.img
22. fastboot reboot


Phone will successfully reboot into system. don't worry, first boot gonna take a little longer time. so have patience and watch some funny video till phone boots up.

Now you can install any firmware version via adb sideload. make sure to install latest lollipop firmware before flashing Marshmallow. follow the guide to sideload.
