    (NEED HELP)dell precision m4600 problem after bios flash (unbrick)

    dell precision m4600 laptop
    i7 2760qm
    8gb ram 750gb HDD
    intel hd 3000 integraded and nvidia quadro 2000m

    pleasea bear with me english isnt my language and ill try to be as clear as possible
    note i live in mexico in a very small town..
    thank you.

    laptop got bricked (freeze at dell logo) i managed to unbrick it but now am facing a problem...... let me explain what and how it happened.

    the brick happened when i was installing win 10 using usb.
    used rufus and officia microsoft.iso
    it finished copying files from usb as in picture below. when it finishes it automatic restarts your pc mine did.


    when it restarted it showed dell logo the blue bar filled up and froze.
    could not enter to bios or pressing any key had no effect. (bricked)

    i search online and found no information about this problem.
    so i tougth motherboard was dead so i decided to get another one. besides i accidentally broke the fan socket

    motherboard worked ok. i had to update from 1909 to 21h2.
    instaled 21h2. run windows update and it broke stuff in windows so decided to clean install one more time and not use windows update.

    so funny thing happened. it got bricked again yes what luck. doing exact samething it did to other motherboard. it copied files from usb restarted showed dell logo bar filled up then froze..... what.??

    ok this time i search for an answer and came up to a guy in a forum that had the same model laptop as me and had the exact same problem as me.in his thread he mentioned he fixe it with ch34a1 programmer. and in there they provided both .bin files bios and EC. but i read that he was having a problem about intel managment engine in recovery at boot.

    ok so i bought me a programmer. am a newbie. was trying to get it fixed as i do not have a job due to panic attacks. and already spent money on pc.

    i asked for help but some stuff i didnt understand. so i decided to flash bios.

    first i tried reading the old board chips and i did that. when i was trying to read on the new board i read 1 the other i could not as the clips would not grab chip anymore. i tried to grab it but by doing so i accidentally clipped 2 or 1 smd pic https://imgbb.com/w0SMKcF



    smd have already been fixed. i used smd from old board and have them solder to the other.. (just want to make sure i tell all that happened)

    ok so i decided to flash bios and fix the brick. read and watched many videos. the way i did this was to have same guy that solder the smd to desolder both chips and have them solder to programmer and again have them soldered back t motherboard.

    tried asprogrammer 141 if am not mistaken. but couldnt find out how to verify it was flashed.

    so used CH341A programm v1.29
    had already back ups.. so read/delete/then write. both chips bios and EC.

    have them back on the motherboard and put it back together... power it on
    bricked is fixed. now i can enter bios and boot to windows (SORT OF)

    these are the files i used. someone share dump files M4600dump.rar

    https://www.badcaps.net/forum/showpo...62&postcount=2

    there is also this files

    https://www.alisaler.com/dell-precis...reva00-bios-ec
    Dell Precision M4600 Brooks 15 EVLT MBF Rev A00 Nvidia N12P-Q3-A1 Bios + EC

    so i used the one from this forum M4600dump.rar
    but the problem a facin is this.

    clean install win10 21h2 boots to desktop all works. (create a restore point)
    restart pc all ok... shut down pc. then turn on. won 10 logo spining circle it freezes.

    enter advanced recovery.. enter safe mode.. then do a restart from safe mode.. boots to desktop all work. turn off then on. freeze at spinning circle.

    enter advanced recovery.. use created restore point.. restarts.. boots to desktop all works.. trn off then off freeze at spinning circle.

    now if am on desktop and update drivers for both hd 3000 and nvidia quadroo 2000m. do a restart all works. can run benchmark. but power off then on.. i get blank screen when windows starts to load.

    so as long as boot from created restore point or enter safe mode and not turning off pc all is fine. but when i turn off and turn on then problem is it freezes using gneric drivers or updated drivers get blank screen.

    i dont know if this problem is bios related.

    Hi did you do clean me region of your bios before you flahing it did you save your original bios dump. I would forst do that . Clean me of your bios. Of that doesn't help i would do an repair of original bios by remplacing me region from update from dell site.

    Good luck

              When the bios is split across 2 chips both of them should be joined together first before cleaning the ME region with flash image tool.

                        its fixed now. thank you all for your help
                        thanks hoaca388

                        since its was my first time flashing bios manually with programmer
                        i made a mistake. i didnt understand when compare files.
                        the program has built in verify file and it said it was the same. but it wasnt

                        all files were not a match

                        A78F433F9CD540B44C0E4464DBFBF747 u52-written.bin (file back up after erase/write and verify.)
                        C1B8EDEC03E771EA9541E5B29486E268 u52ok.BIN (file used to write chip)

                        130E8A3F0A44F69410A18883FF4512FC u53-written.bin (file back up after erase/write and verify.)
                        395FA0DA4DC293882FCF5DBF24E6FECD u53ok.BIN (file used to write chip)

                        so now with hoaca388 uploaded files i flashed both chips made a back up after flash. then with md6 sum check i created md5 and both files matched

                        8FDB2B2E133230A1F349E1BF2187DE5C oldboardbk-u53-New8mb.bin
                        8FDB2B2E133230A1F349E1BF2187DE5C new-FIX-BK-U53.bin

                        C1B8EDEC03E771EA9541E5B29486E268 new-FIX-BK-U52.bin
                        C1B8EDEC03E771EA9541E5B29486E268 oldboardbk-u52-New-2mb.bin

                        now with this bios i can see intel ME bios section
                        that is this for.?? it ask for password.. or should i just leave it alone.?

                          NEED HELP

                          first i want to ask this.
                          before flashing provided files from hoaca388
                          when i pressed F12 i would see

                          bios set up
                          diagnostics

                          now after flashing hes files it shows this option too
                          intel ME mbx...

                          before hes files when i updated bios from dell A08.exe
                          it will show flashing bios reach 100 and restart.

                          now with hoaca388 files after a dell bios update using A08.exe
                          shows bios update it completes then now shows updating ME firmware it finishes and restarts.

                          is this how its suppose to be.????? because the ME option in bios appears and updating bios with A08.exe it also now shows updating ME firmware.

                          NEED HELP..
                          after using laptop i have noticed that its slow.
                          before it would take 1 second from log in screen to desktop
                          now computer is slower. takes time to boot. after log in screen takes a while and also when i remove index from C it took a longer that it used to.
                          what to do or how to trouble shoot this.?

                              can you please tell me what is the difference this file to th other.?
                              and can you please tell me why now intel ME extension option appear.??
                              i ask because i have never seen that option before.
                              thank you.

                                hi. just flased this yesterday. laptop was just a bit slower on previous file.
                                with this clear-ME file. performs better its faster.
                                but i want to ask you something.? on previous files BIOS version was on A04
                                but when i flashed this clear-ME file its at A19 .??? is this supposed to be on A19 or like other file A04.? because laptop version was on A19. makes me wonder if it didnt flashed correctly.
                                may i ask for file link needed to clear ME.? i want to learn how to do it. i just dont understand wich file to download. and also would like the file to update intel managment engine..
                                thanks

                                      Hello,I was installing window 10 on my dell precision m4600 service tag : 4zqs4s1 , and after installation complete and restart it's freez in dell logo , I searched and realized It need bios flash so I found this https://www.alisaler.com/dell-precis...reva00-bios-ec
                                      As I live in a small city and I don't have programmer sed it to a repairman to flash this but after flashing and boot up , touch pad didn't work , the USB or pexe boot don't boot and only DVD drive can boot , also the biggest problem is in f12 menu there is no Intel me mebx and the worst thing is after installation windows every time I shout down or sleep or hibernate it's freez in windows logo and I should go to safe mode and everything turn ok until I shout down or sleep and it's a cycle.
                                      After all that I found this : https://www.badcaps.net/forum/troubl...-flash-unbrick

                                      It's seem that guy flashed my bios don't know what is clear me region, like my self and that happened To my laptop
                                      Now my question is my laptop CPU is : I7 2820qp and I don't have the default dumped file , it will be ok if I use the last bios file with clear me that guy uploaded in to that
                                      Topic or I should test different me version?

                                      I apologize for my English, thank you in advance for your answers

                                      hello guys,

                                      i've got a probleme with a laptop precision m4600
                                      the guy that brought me this one tried to update bios but don't know wich one it used
                                      actually the laptop post, got dell logo for long time then "ME in recovery mode" message
                                      so i think bios is corrupted

                                      as the laptop is hard to dismentle i would like to try flashing it with usb drive, but i think direct flash from dell site firmware will not work.

                                      can someone can build a bios for me ? the service tag of the laptop is : FYNZ4S1

                                      don't have already bios dump as i have not dismentle this one at this time

                                      thank you guys
