Hi! I have successfully update my S90-A, but no pop-up menu shows after dialing ####5993#. It only shows the internal version (i.e., S90A_S229_150428_ROW_Notset). Can you help me with this? And what is the purpose of the region code? Thanks in advance.

Reply to Mark Franco

if ####5993# dont show anything try to using ####59930#
it for do factory reset and give country code to your device, it use for OTA update to recognize your device.

hi sir . ive just downlaoded it .. after applying the update firmware from sd update its says INTERNAL : invalid signature .. how can i fix it sir ? .

Go to recovery mode or system setting find the factory reset button and do factory reset so it will format all data and sd card on your device, backup sd card first

INTERNAL : invalid signature
Same error to me. I am doing factory reset but no change… How to fix?

Reply to Alexander Ivanov

check your custom recovery, this update must be use original non change stock recovery.

The phone is stock. It is with stock recovery.

than maybe you have root your device or anything that change the system files

Reply to felix78ace

Have you tried to root your device? Installing custom rom because update this need all in original stock of lenovo, so if you got invalid maybe one of the above reason
