<<< Samsung eMMC Write Protection Removal >>> - GSM-Forum

Advance-Box · 02-28-2015, 16:24

1. First Make sure eMMC inside your phone is Samsung Brand. If any other brand like SK Hynix, Toshiba, Sa.ndisk etc... then this solution will NEVER WORK.

2. So if eMMC is Samsung, just wire eMMC Connection and do this:
If you do not know eMMC Pinout, then you can Find the eMMC Pinout via following Steps here:
http://forum.gsmhosting.com/vbb/f609...orial-1908984/

So here we see eMMC is SAMSUNG Brand and PERM_WRITE_PROTECT is YES...
This means eMMC is WRITE PROTECTED...

So here just select Advance Function "Samsung Remove Write Protection" then click "YES".

After Operation will finish, click "SCAN EMMC" again to see the updated Write Protection Information... see here it is already Removed...

*** This procedure WILL NOT TOUCH DATA on your eMMC. Whatever was inside your eMMC before the procedure is 100% same as after the procedure, except only that Write Protection was Removed! ***

Because some phones get Write Protected due to BUG in Phone Operating System and Samsung eMMC Firmware.

Example, many complained about getting WP = ON after updating their Lumia 520 to WP 8.1. This bricks the phone... We cannot boot repair it because it is WRITE PROTECTED. So need to remove Write Protection to fix the Phone bug.

bk.gsm · 02-28-2015, 16:37

this method will work with all new phones that have Samsung emmc chips??and what about htc devices..u know there are too many modules like desire 500,300 and 700 have same issue.

@bk.gsm

1. First open phone. Check if samsung eMMC Inside.

2. Then check 1 phone, connect with eMMC Tool to see if WP is ON...

If both 1 and 2 is YES, then you will be able to fix it.

If you can show me that other eMMC Brand also have WP problem, then I can check on these brands as well.

Quick question : how to connect to the eMMC DATA in Lumia 520?
According to the scheme there is no matching components (resistors).
