Editing Template:QA dehashing

<ol>
<li> Patch as normal downgrader (ROS 0/1 + RVK prg/pkg)</li>
<li> install prepatched firmware in factory service mode</li>
<li> use the lv2diag.self [file2] to exit factory service mode</li>
</ol>
Above is already done if you just downgraded

Dump the flash first, in case you brick on dehashing, you can easily flash this one back to debrick
<ol>
<li> Install and run [http://www.ps3devwiki.com/wiki/QA_Flagging#Toggle_QA_-_rebug.me QA-toggle] and make sure it beeps as written in that readme
<ul><li>Note: for above to work, you need a BD drive connected and married to the console (except [[CECH-25xx]] and later).</li>
<li>Note: to make sure you enabled [[QA_Flagging|QA]], not accidently disable it, do the button combo (if it shows [[QA_Flagging#Debug_Settings_.28CEX.2FDEX.29|menu]], then console is [[QA_Flagging|QA-flagged]] correct. Remove the QA-toggle package to prevent it from getting QA-flag reset).
::''Set your cursor on (not in) Network Settings and press the key combo (all at the same time): L1+L2+L3(press_left_stick)+R1+R2+dpad_down''</li></ul></li>
<li> Make sure no disc is inside BD drive and Poweroff console
<li> Put unpatched official firmware (e.g. [http://www.ps3devwiki.com/wiki/3.55_CEX 3.55]) on USB Mass Storage device as /PS3/UPDATE/PS3UPDAT.PUP and insert in PS3
:Note: It has to be a firmware without 'downgrader patches'
<li> Boot into [[Recovery Menu]], select "''6. System Update''" to reinstall firmware.</li>
<li> If installation finishes without error (there will be no logs you can check!) and boots XMB OK, then dehashing was successful ''(the really super paranoid people can do step 4 twice to make sure that both ROS are rehashed)''.<br />Congrats, you now finished downgrading and dehashing. Console runs 3.55 and any firmware of choice can be installed, no longer needing to be patched for downgrader.</li>
