hi new 7355 , just installed. problem is that device remain in LOW power mode so show no service (read sim with no problem).

i Flashed with last generic Firmware version and latest driver. even in this case no way…win10 just formatted.

here it’s my gstatus:

Current Time: 2501 Temperature: 20
Bootup Time: 6 Mode: LOW POWER MODE
System mode: TD-SCDMA PS state: Not attached

skylight say to me no active service.


Help!! :confused: :confused: :confused: :confused: :confused: :confused: :confused: :confused: :confused: :confused: :confused: :confused:

going on…

can i ask you WHY TD-SCDMA ? i’m in europe and this should be different…

is there any way to switch to Eurpoean network mode by AT command?

It’s gonna be a discussion between me and me :smiley:
btw as i understand it’s a specific sony vaio problem and sony has discontinued products i’m posting here solution as could maybe help someone else.
First: the card is working perfectly.

For some reason sony guys has decided to put w_disable pins to high (think to save power) this cause card to go Low Power mode.

ONLY SOLUTION, as sony is no more releasing any driver is hardware. you have to mask W_disable#1 and W_disable#2 on datacard (pin 8 and 26 of ngff m.2). Those 2 pin control ON OFF state of the card.
This bypass sony error and make card live again ( even if cant be turned off)
