Security Backup.

Customer had Modded firmware previously, all back in stock now, device is fully working, but can't unlock.

I found LINK HERE this thread with succesfull job, same log, same details, but with SigmaKey 2.06.05, so I have unsupported device? Damaged device? Or SigmaKey 2.06.05 was unlocking it, but latest version has some bugs? I really would like have it unlocked, when I try "Get unlock codes" it shows 3 levels NCK, NSCK, SPCK but no codes.

Are you testing unlock in Manufacture Mode

@ mahcin,

Try servicing this device via manufacture mode and post results in a current thread, please.

Thank You, I tried that but as far as I know to enable "manufacture mode" I need to enter in dial pad code *#*#2846579#*#*, select "Project Menu", "Background settings"

but then I haven't option "USB ports settings" or "Manufacture mode"

I have:
1. Qualcomm background open setting
- background open
- background close (default)
2. Log Setting
- Log switch
- Duraion for saing logs
3. OTP NV filter switch
- OTP NV filter open
4. USB PID Switch
- USBPID_HUAWEI_S7_MTP_ADB_DIAG_GMDM_GNMEA_MSC_RMNET
(off as default, so I assume it may be it, so switched on)

but nothing, same problem, any advice please? Device is fully working.

[mahcin]

okay, after research it looks like in my case I need password for it, as Manufacture Mode would be under:
1. Qualcomm background open setting
- background open
- background close (default)

When I change to open, it ask for password, I stuck here, bootloader unlock?

Unlock Huawei bootloader option gives me:
Please send
C:\xxx.skb
file to [email protected]
Inconsistent file

Get Huawei bootloader password gives me:
Please send
C:\xxx.skb
file to [email protected]
Inconsistent file

is S7-303u fully supported for unlock?

[mahcin]

I sent file yesterday, could You please help with it? Or if is not supported please just let me know.
