    i've seen on interne that it could be a bios related problem

    following a youtube guide,i've cleaned me region

    after that, powering up the mac, the apple logo appeare after a lot of seconds and stuck there with fan at full speed.

    so i've tried one bios downloaded from internet but not laptop is dead (even with the original dump)

    i cant power on it anymore with battery or power supply. i've light on mag safe but it is completely dead

              Bios requests go in the "Bios Requests ONLY!" forum here:

              https://www.badcaps.net/forum/forumdisplay.php?f=40

              Start a new thread or find an existing 820-3332 thread to post in and attach your bios backup in a zip or rar,and also post the serial number

              .

                      How to program a specific flash region of a Nations N32G455RE MCU?
                      by Nikan.e
                      Greetings and salutations!

                      I have a device that uses an N32G455RE. Unfortunately, its flash got corrupted. I have a dump of a working chip.
                      How can I program a specific region of the flash or the whole flash without touching the RAM, option registers, etc.?
                      I do not have a J-Link debugger and won't buy one, as I am not rich.
                      I have flashed a Nucleo board with an ST-Link to a J-Link just to find out that the ST-J-Link only supports ST chips.

                      What would be the cheapest and easiest option to program the Nations chip's flash without touching registers etc.?...

                      Thinkpad t480s, completely dead after BIOS flash using CH341A programmer
                      by what_1282105
                      Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life....

                      Winbond 25Q16JWNIG – Asus ROG Strix Scar 18 G814JZ bricked after wrong flash – Need help
                      by Vincent Kahle
                      Hi everyone,

                      I hope someone can help me.
                      I have an Asus ROG Strix Scar 18 (G814JZ) laptop with a Winbond 25Q16JWNIG chip on the motherboard.

                      Unfortunately, I flashed the wrong file (BIOS/EC/other region – I'm honestly not sure anymore), and now the laptop is completely dead: no display, no fan spin, no reaction at all.

                      I have a CH341A programmer and I'm able to read and write to the chip. However, I'm not sure which software is best (AsProgrammer, NeoProgrammer, etc.) or if there's anything specific I should watch out for.
                      A valid BIOS/EC backup...

                      Canon VIXIA HF S10 A read data from inernal flash memory.
                      by abajor
                      Hello I've had somebody bring in one of these charming little cameras to attempt retrieving data from the internal 32GB flash.
                      Something is damaged inside the cameras lens assembly I can hear it clunking around and it has probably dislodged the sensor, powering up the camera gives a blank screen and the focus motor sounds like it's having a fit.
                      The camera will not connect to a computer via USB in this state, I have no options no navigation, just power up and focus/zoom motor noises.

                      I think my best shot is to figure out a way to read the internal flash memory outside...

                      by Ihandyrepair
                      HI guys

                      I got here a Sony 65X950G - I tried to find any repairs guides for this model but not many online

                      here is the issue
                      I have Sony and android logo. but then 4 led red flash lights front of the tv

                      I have 3.3v ref. 12v reg then T con 12v when I press the power on button
                      but then I get black screen and 4 red flash light at the front LED
                      but I get 3 led flash on the LED driver board.

                      I check that few X900F or C YouTube repairs, seems that if you have 4 led red flash it could be due of LED black light error
                      so I tried...
