    Hi to all,

    Help needed with bricked Acer Extensa 5635g (phoenix bios): in hopes of better fan control I tried to update the bios to the newest version, which crashed on me at the very end. After reboot everything seemed fine, but display stays black and after a while 2 short beeps followed by a long one come up (this would be the graphics card).

    So I started trying out varioius versions of crisis recovery, none seem to work for me so far. here is what I tried:

    -when I use an older phlash16.exe and the correct bios renamed to *wph with a crizdisk formatted stick (less than 2gb), recovery seems to work at first, but after reading a bit from the stick I get an undocumented beep code: 4 short, pause, one short

    -when I use the correct bios with the phlash16 that comes along with it, the stick will be read shortly at first, but nothing else happens then, and there are no beep codes

    -after mailing to acer, they gave me the flas**t.exe from aspire one and told me to use the .bin bios file for my notebook along with it, though I think they don't know what they are talking about, since to my knowledge the flas**t.exe is waiting for an .fd file with the correct name

    -I tried the same with a flash card, and the old phlash16.exe gave me yet another beep code which I don't recall right now

    Since I am left with so many variables so far, I don't see a way to verify which course to take and to find out what is wrong so far. Due to different outcomes depending on the combination of files I use, I don't think the MB/Bios Chip is wasted yet. It seems rather like the crisis update is waiting for a different file or file name depending on the combination I use.

    Mates, any solution is welcome, since I am close to giving up on this notebook.

    Before you ask, I have read the post on recovery methods, hell, what have I not read :) There has to be someone else in the world who was stuck with a bricked 5635g or related model


    I have also learned qite a bit about the phoenix bios on acer laptops, that is not in the recovery post. For instance:

    -the disk, stick, flash card does not have to be bootable for crisis recovery and can be formatted in fat OR fat32 (at least that is acers official statement)
    -you do not need a *.bat file for crisis recovery since it wont be read anyway, it is for dos flashing only, so you wont have to rename the bios file to bios.wph, which is the filename the phlash16.exe is looking for by default
    -that also means that there is no way to use any switches on phlash16.exe for crisis recovery, which are mostly set by acer by default in the *.bat

    correct me please if something seems wrong!

    Thanks in advance, starvinmarvin

    ps to admin: I tried to delete my original post in bios recovery methods, since I felt nobody would probably read it on page 116, but please move it back there if you think otherwise.

    Extensa 5635/5635Z/5235 Service Guide says on how to recover:
    BIOS Recovery Hotkey:
    The system provides a function hotkey: Fn+Esc, for enabling BIOS Recovery process when the system is
    powered on during BIOS POST. To use this function, it is strongly recommended to have the AC adapter and
    Battery present. If this function is enabled, the system will force the BIOS to enter a special BIOS block, called
    Boot Block.
    Steps for BIOS Recovery from USB Storage:
    Before doing this, prepare the Crisis USB key. The Crisis USB key can be made by executing the Crisis Disk
    program in another system with Windows XP OS.
    Follow the steps below:
    1. Save the ROM file along with Flas**t.exe (aka Fla.exe in some bios versions) (BIOS flash tool) to the root directory of the USB storage disk.
    2. Plug USB storage disk into the USB port.
    3. Press Fn + ESC + Power buttons. Remove your finger from the Power button but keep the Fn + Esc keys
    pressed till the Power button flashes once.
    Note: During the first iteration, the LED of the USB disk will keep flashing for about 3 - 7 minutes. After this, the
    system restarts. You can check the BIOS version after the system restarts. If correct, the crisis system is set up
    correctly.

    Thanks for the quick reply, unfortunatly:

    post #5 theeldergeek.com
    and last post Fn Esc

    I have been there already, but didnt work for me.

    And I have read the manual, but it talks about a rom file, but what rom file? Do they mean *.rom, of which there are none for my model? Do they mean a binary, of which there is just one *.bin for my model, and even then, should it stay *.bin or be renamed to *.rom? The flas**t.exe seems to be for *.fd files, none are available for my model.

    Yeah, thats the dilemma I am in :)

    Hi,
    I know this thread is rather old but I want to say I am stuck exactly in the same situation. The same notebook, the same behavior (using 256MB flash stick with LED blinking correctly according to the operation, like the HDD LED, not just any regular slow blinking frequency - so I discovered that the first three beeps are followed by immediate reading from flash, while the fourth beep is not, there is a slight pause and then the last beep, perhaps someone would know what that means).

    I tried several crisis disk versions, none of them is leading to a success. I now ordered a local acer service, the bad thing is that if they fix it, I would not know what was wrong :( (and I would be probably able to brick it again stuck in the same situation).

    Has someone already figured out what can I do myself (before the transport service arrives?) Thanks in advance.

    Just want to note that I resolved the issue by desoldering the BIOS chip, programmed it (.BIN file from Acer web) in a programmer purchased on ebay and soldered back. Notebook is alive again.

    Authorized service told me it is necessary to change the whole board and it would cost me a fortune (almost the price of the same notebook). They returned the notebook back to me at no cost (which was surprise for me because in their service terms is quite a big fee for sending it back unrepaired).

    cheap CH341a to the rescue!

    desolder ? sop8 test clip wire sometimes works on the board.. if it doesnt.. you plug in power cord to supply power to chip and resistors sometimes works.

    to clarify. the .bin file is also in folder with .wph ?
