[Sony Cross-Device General] munjeni:
Well, trim area hold some information which you need to change yourself, you should read information first from phone, this is example:

// 58.0.A.28.25

// newfasher Read-TA:2:2202

0000089A 000C 35 38 2E 30 2E 41 2E 32 38 2E 32 35

// GLOBALEEA-A2

// newfasher Read-TA:2:2801

00000AF1 000C 47 4C 4F 42 41 4C 45 45 41 2D 41 32

// Unknown: Nov 2 2020/19:18:21 -> it should be something like GENERIC_58.0.A.28.25

// newfasher Read-TA:2:2206

0000089E 001D 55 6E 6B 6E 6F 77 6E 3A 20 4E 6F 76 20 20 32 20 32 30 32 30 2F 31 39 3A 31 38 3A 32 31

// Unknown: Nov 2 2020/19:18:21 -> it should be something like 1317-7500_R12C

0000089D 001D 55 6E 6B 6E 6F 77 6E 3A 20 4E 6F 76 20 20 32 20 32 30 32 30 2F 31 39 3A 31 38 3A 32 31

// XQ-AS52 -> this is device model

// newfasher Read-TA:2:2210

000008A2 0007 58 51 2D 41 53 35 32

(explanatory example of the .ta file structure)

E.G. Information given from phone is in HEX format, and this is explanation:

00000AF1 000C 47 4C 4F 42 41 4C 45 45 41 2D 41 32

AF1 -> hex unit (in decimal 2801)

C -> size of the hex string (size of the green part in hex its C, when you convert C to decimal its 12, in our example GLOBALEEA-A2 contain 12 characters, 12 dec when convert to hex is C)

47 4C 4F 42 41 4C 45 45 41 2D 41 32 (string in hex format, when you convert it to ascii https://www.binaryhexconverter.com/hex-to-ascii-text-converter you get GLOBALEEA-A2), if you count number of chars its excatly 12)

Tools you need for all this is:

ascii text to hexadecimal converter -> https://www.binaryhexconverter.com/ascii-text-to-hex-converter

hex to string converter -> https://www.binaryhexconverter.com/hex-to-ascii-text-converter

hex to decimal converter -> https://www.binaryhexconverter.com/hex-to-decimal-converter

decimal to hex converter -> https://www.binaryhexconverter.com/decimal-to-hex-converter

In reverse order e.g. when you need to change something in your trim area you should create e.g. myown.ta file to flash back with newflasher (take all this as an example!!!):

// partition (do not change this & always 02 !!)
02

// 58.0.A.28.51
0000089A 000C 35 38 2E 30 2E 41 2E 32 38 2E 35 31

// GLOBALSEA-A2
00000AF1 000C 47 4C 4F 42 41 4C 53 45 41 2D 41 32

// Unknown: Nov 2 2020/19:18:21 -> you nedd to figure it yourself, it should be something like GENERIC_58.0.A.28.51
0000089E 0014 47 45 4E 45 52 49 43 5F 35 38 2E 30 2E 41 2E 32 38 2E 35 31

// Unknown: Nov 2 2020/19:18:21 -> xperifirm CID of the SEA fw, it should be something like 21610788
0000089D 0008 32 31 36 31 30 37 38 38

Do in mind this is just explanatory examle only!! Dealing with trim area is extremely dangerous (some units is extra extreme dangerous & never touch it e.g. hw config, sim lock, sim signature unit, probably more!!!) and your device if you do something wrong (e.g. write wrong size of the hex string) by writing your own trim area .ta file it might hard brick your device!! You guys need to figure out yourself and again double check before flash those custom .ta file!!! I can sugest you to open new thread in your device forum and point our example post as a reference until somebody figure out what excatly need to be writen in custom .ta file while flashing firmwares! Again, no error in newflasher window mean no problem with newflasher & not newflasher isue, so please do not repeat. Also I can sugest somebody give output of the folowing commands (from fully stock & never flashed device):

newfasher Read-TA:2:2202

newfasher Read-TA:2:2801

newfasher Read-TA:2:2206

newfasher Read-TA:2:2205

newfasher Read-TA:2:2210

It might help you better figure out things
