==== Remarks ====
 
<!--// '''ReFSM''' way is strongly recommended over '''QA''' if you do NOT install a nonpatched firmware //-->
 
* FSM gets you a installer LOG (QA does not)
 
* FSM does not delete ACT.DAT ([[QA_Flagging#Act.dat_.28PSN_activation.29_gets_deleted|QA does]])
 
* FSM can be done without a BD drive with noBD patched firmware (QA needs the BD drive present)
 
* FSM can be done without seeing XMB or Recovery (QA needs Recovery and XMB for the QA-flagging package)
 
 
Both ways ''require'' installing nonpatched firmware to dehash syscon bank. QA-flag can be removed/reset (but it is better to keep it flagged) after succesfull dehash, without bricking.
 
 
 
  <domelec> dehash procedure: fsm install ofw
 
            after console turns off take out usb stick and look at log file,
 
            if log is ok then reinsert usb stick and turn on console,
 
            ofw will then reinstall, after console turns off again
 
            take out usb stick and check log, if ok then exit fsm
 
 
  <eussNL> do double FSM OFW, then get out of service mode.
 
  <eussNL> check everything is working
 
  <eussNL> THEN and only THEN, you can install whatever you want, in recovery.
 
  <eussNL> there is no need for factory mode after dehashing complete
 
  <eussNL> in fact, if everything works on OFW 3.55 after dehashing,
 
  <eussNL> you can install [http://www.ps3devwiki.com/files/firmware/MFW-CEX/Downgrader/Rogero-V3.2/ Rogero V3.2] in recovery and [http://www.ps3devwiki.com/files/flash/Tools/toggle-qa/ QA-extra] flag it 
 
  <eussNL> if OFW 3.55 works then you proven that you dehashed
 
  <eussNL> so after that you can install whatever MFW 3.55 you want
 
 
  <eussNL> If for some reason you cannot dehash because of BD or BT errors
 
          then you can use PS3MFW Builder and the broken Blueray / broken Bluetooth
 
          tasks. Do not select downgrader patches, or you will not dehash!
 
 
  <eussNL> BD error can be persistant if flasher is still attached,
 
          see: http://www.ps3devwiki.com/wiki/Talk:Hardware_flashing#BD_drive_not_found_problem
 
  <eussNL> 3 options: 1. open R7/R8  /  2. remove flasher control lines / 3. remove all flasher wiring
 
 
  <playonlcd> i  think you can update on wiki "dehashing with jaicrab is not recommended
 
              and will not dehash as needed and thus semibrick by syscon hash panic
