[Tutorial] How to modify your EBR and change your partitions for MTK6589T, MTK6582

[pacoppes]

This is my existing EBR1 and EBR2 from Gionee's GBW192. The size of /data is 2,264,924,160 bytes (based on MDT Block Info).



The value is different from this tutorial, and that's why Meteos repartition tools are not working properly in my device.

Your current size is: 0x00438000 ie 4423680 sectors (* 512) = 2264924160 bytes = 2.109375 GBytes

For every 0.5 Gbytes you must add 0x10 to 0x43 of EBR1 (01ec position), for example if you want 1 other Gbytes, add 0x20:

Substitute 0x43 by 0x63, ie:

0x00638000 = 6520832 sectors = 3,338,665,984 bytes = 3.109375 Gbytes

In EBR2 you must add 0x10 to 0x63 (position 01C8) and subtract 0x10 to 9A (01cc position) for every 0.5 Gbytes.

For example if you want to add 1Gbytes would:

0x63 + 0x20 = 0x83
0x9A - 0x20 = 0x7A

Thus becomes:

EBR1 position 01ec: 0x63
EBR2 position 01C8: 0x73
EBR2 position 01cc: 0x8A

A greeting.
