Hello! Tell me, how to manually change the values of registers ext_sd?
For example, if I put a chip in the phone MTK, I definitely need to change [RST_N_FUNCTION] bit.
I want to have configuration buttons for different types of processors.
I want to have a button of infinite random testing of the memory section. This operation should not be destructive. Read the original data from the sector, recording test data, test data reading, verification, recovery of the original data.
Request to the developers.

ProOFF how to manually change the values of registers ext_sd?

Have you rewritten ext_sd from file backup and see difference before rewritten?

I have 10 completely dead memory chips from different devices on mediatek processors. I do not have any backups for this section.
Look at the picture.
this bit

The program requires "hot keys", which can be configured by users for a particular type of processor.
For example, pressing the "hot button" "MTK" will change three registers in ext_csd
1- [RST_N_FUNCTION] 162 '1'
2 - Boot bus conditions 177 0x00
3 - PARTITION_CONFIG 179 0x48

You can provide "expert" mode. In this mode, the user himself can create the hot buttons he needs with the necessary configuration.

At the moment I have to repair the memory this way.
ic clear
Next, I configure the registers 177 and 179 for the processor MTK.
STEP1
STEP2
I click identify eMMC and I'm looking at the log.
The memory is not fully configured - the bit "[RST_N_FUNCTION]" has not been changed
rst
Here is the ext_csd file read from this chip.
162 no change
I open this file in a hex editor.
open orig file
I change the required byte by hand.
correct
I save the modified file and write to the chip
Program writes Hardware reset function bit is enabled
write
I click identify eMMC - LOOK GOOD!

But this procedure is very uncomfortable!

Wait a 2nd.. Did u have trouble with that 3 registers ? I dont think so..

U must try make a conclusion correctly coz that all bit slice is auto set by cellphone host in the middle of power up squence.

Trust me.. In old ufi version already have try make it visible (registers changed) but it doesnt much significant to users when process of repairing taking place.

You really tried to restore the memory chips of the Samsung ??
Did you NOT install a reset bit and install the chip in the phone?
You flash the phone and it turned on after the reboot?
Do not mislead people!!
The Mediatek processor can not change this bit!
For a long time I could not understand why tablets brand "prestigio" "wexler," texet " after the flash firmware are turnon once!
After rebooting, the tablet does not turn on until it is flashed again.
The problem was exactly is in this bit !!
Once again, if you know this in theory, try it in practice.
It was in repair a lot of chips "klmag2ge4a-a001" this bit MUST be set to "1".
Return to the program the button of this bit, it is necessary as air !!
Or do it as in another programmer - the buttons of the preset configuration for different types of processors.

This is rare case, The reply from Dujeh_Djajadinata is correct, in theory. But there's always a rare case, and it seems that it needs an exception, especially for some brand like ProOFF said. So, will add in next update as "expert" mode 😉

Big, many thanks !!

Please add a test of RAM in the mediatek processor in the new version. So, how it is made in flashtool 3.хх. In ufi android.
Thank you.
