Did hardware already and flash to 665x with SigmaBox but now is not turning on. I flashed the backup and work fine with no signal. What flash should I use is a T-Mobile's ot-665a. Here's original flash name : 665A-2ATBUS3-R 79L XL79QMB7JRD53_09B_PCB01_GPRS_MT6253_S00_MAUI_09B_W 09_52_SP1_V12_F7.skb

You must See if it is Samsung FlashICs or Numonyx FlashICs, cannot use without knowing that's why it does not start, you must modify hardware, upload a picture to help.

My friend you must flash with 665X-2AWNIT3_763_XL76CK11_JRD53_09B_PCB01_GPRS_MT6253_S 00.MAUI_09B_W09_52_SP1_V12_F7_DE_EN_ES_FR_IT.mfw
(There are any Alcatel phone with two Flash ID: example.. Ot-606 1-Numonyx and Toshiba, in the firmware you can see this: 0098-005F-0000-0000 or this: 0089-8904-0000-000)
