what machine do you now to flash ?

if you use roemmi, when you plug phone to box, do the led in box light?

if so ,prepare the data and flash it ,when flash notice the memory ID and check what models of this memory.

some memory is difficult to flash for:28f320c3b.

the ID is :

28f320b3b :00898897 (this is easy to be flash)

28f320c3b :008900c5

special notice this id.

i get this site back email today about roemmi box.

Hello Raino,

Now I have Roemmi box with moto key.

I use Motowin sw.

My roemmi has only one led green, if I sw On phone Led change to yellow.

But I connect my dead phone, sw On and nothink.

I hear about possibily flashing by test points.
But I don't have anny info about it.

Best Regards

hi

come´on, if phone had bad flash and don´t power on vcc to test point is needed to reflash it, so forget about ´magic´solutions and find test point in board,

you can find memory's CE ,usualy the CE is in the pin26 ,if the memory is intel and is tsop packeg.

if the memory is BGA, you must check the schematic and find CE.

After find out CE ,you can use logic pen to trigg it when flash.this is china's method ,becourse phone' cpu will check the memory if correct or not ,when cpu find the memory is empty ,will download from external ,when ce level is high ,cpu will think the memory is empty. so flash auto.

if you no logic pen you can connect vcc to CE and power on phone,when the led light cut the line from vcc.

of course we can flash with roemmi i think with same method.

or write memory with universal programmer lt48 .
