Lenovo G50-70, bios update wrong checksum

Q: Lenovo G50-70, bios update wrong checksum

Greetings!I have a Lenovo G50-70 notebook it worked fine so far, but recently I got some UEFI related treat warnings from my antivirus scanner. I'm not sure if its a falsepositive or not since I'm extremely paranoid about security and always make extra precautions to avoid nasty stuff getting on my computers, but just to be safe I wanted to reflash my BIOS.However when I head to this official download page: https://support.lenovo.com/us/en/downloads/DS100522The BIOS update related cheksums are all wrong for me. The file I download has a completely different set. I would be very greatful, if someone could look into this for me. I don't want to end up with a corrupt or tainted update file during the flashing process.Thank you very much in advance and have a nice day!

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hi, Because of many crashes and a Windows messages telling me my BIOS was probably out of date I updated it through the Micro Star International
MSI Live Update Online. During the download process it gives you the option to backup your existing BIOS settings to a floppy. I don't have one so had to bypass. It seemed to worked but when the operation restarted I didn't know what I was supposed to do. In any case it rebooted but on that startup screen it said 'Checksum bad'. When XP loaded I got the 'the system has recovered from a serious error' message again. I thought that I must have done something wrong. I went throught the whole process again to update the BIOS process. XP loaded OK and everything seeme to work. Becasue of the previous problems I thought I had better check and restarted. I tried Pause/Break to freeze the startup screen bit by bit. But I couldn't grab the last line even with multiple attempts. No matter howm many times I tried I just couldn't read the last line,which I think said something about the Checksum' . But couldn't make out whether it was bad or good. In previous viewings when it was 'bad' it was slower. Can anyone explain what is happening or how to capture the last line of text.
Sorry to be so longwinded but I hope someone can illuminate what is going on.Thanks.

Hello,

a friend gave me his HP DV6500 Notebook to fix it. He said it made an update and then for hours nothing happened. He shut it and started again.

I could see that it tried to recover 2 times. The second time it was successful but it somehow resetted or returned the Vista to a fresh install!!! His data was locked in a previous User account, I backed it up on a usb-stick with a linux live cd.

I can't make a reinstall because now a bluescreen always appears even when I boot from Vista DVD.

ntoskrnl.exe corrupt when try to boot vista in the normal way.
How can I fix that without being able to use the repair option of the DVD?
Sorry, the title of the thread is wrong. I figured out already that the BIOS version is for an Intel. So everything is ok with the BIOS actually.

Hello everyone! I ama new user and i am coming up with this post as I couldn`t find any kind of solution for my problem.Recently I decided to do a reinstallation of my operating system, which also previously was Windows 7 Ultimate (x64). The installation went as usual, and after finishing it I went on to install all the latest drivers from the Lenovo site, for my product. When getting close to installing almost all the drivers i`ve needed, i stumbled upon a new version of the BIOS amnd the drivers and sfotware recommended for my laptop, by the producer. So i proceeded to install the upgrade, restarted the computer when it prompted me to do so, but after the so-called restart the laptop did not boot up as usual. At first it was telling me to not do anything as the BIOS is being flashed and then it was telling me something about some sort of image processing, things that i did not understand at the time (i have never encountered anything like that). After that my screen turned black. I have not done anything for a few couple of minutes as i thought it was supposed to be like that, but then i just force shut it down and unplugged the AC adapter. When trying to boot it all up again, the only thing i got was a black screen and nothing else.After doing a little bit of research it appears that, somehowm i`ve managed to corrupt the bios on my laptop or something, and nothing else would work at this point.

I?m currently updating the BIOS of some Lenovo ThinkCentre M83 PCs and I came across a problem. The Flash UEFI BIOS update (provide by Lenovo) worked almost perfectly on the first PCs, despite it didn?t automatically open the console and started the flashing process.Anyways I did go on with my work.

Hi. I have a Lenovo B50-30 mode 80ES. It was set to require a password on startup starting with a capital "A". While experiencing charging problems, amongst other things, I updated the BIOS to 9CCN35WW, downloaded from the Lenovo support site. Since updating, the laptop no longer asks for a password on startup (No big deal, I applied a windows password), however, when pressing F2 to access the BIOS (which I need to do, the F keys are the wrong way round), it asks for a password, When pressing to strike a capital A, the laptop beeps and doesnt enter it. It wont accept capital letters anymore, therefore it wont accept the pre BIOS update password. I have referred the laptop to Lenovo service, including returning the laptop, and they have been nothing short of useless. They said they couldnt repair it under warranty because of "Marks, cracks, inappropriate treatment" and it would cost 255 for a replacement system board. I really couldnt see why I should pay for an issue created by their support system, so I asked them to return it unrepaired. Upon arrival, the laptop was immaculate, so I dont know what damage they were referring to. Is it possible to downgrade the BIOS to a pre update revision, to change the password and then reset it to one the new BIOS approves of? Thankyou in advance.

Hi

I hope this is posted in the right place.

I think I have messed up my computer big time and need some advice.

I was trying to update the BIOS on my Medion 8838 because I wanted to use more than 4GB of ram.

I downloaded the BIOS update from the Medion website booted the computer into DOS and applied the update.

Everything seemed to run smoothly with the update and when it finished my computer rebooted but just kept on turning on for about 2 seconds and then turning off again like it is stuck in a loop.

Now whenever I plug in the computer this loop of turning on and off starts again.

I have tried resetting the CMOS but to no avail.

I am seeking advice on what I can do.

Is this fixable?
Do I need a new motherboard?
Is my computer dead?

Any advice would be much appreciated.

A few days ago i found an update for my BIOS. It was installing without any problems, but around halfway of the intallation, a power surge caused my computer to shutdown. When the computer booted back up I got this message. This is all I get, I can't access the BIOS or anything pass this
I tried removing the CMOS battery, I also tried to cross the jumpers, all with no luck. This only leads me to believe the BIOS itself is corrupted. I heard there is a way to fix the BIOS by using something called flashing. Could someone show me how to do this?
 

A:Bios update gone wrong

Flashing your BIOS is what you where doing. Depending on your system you may be able to use the Boot CD to restore the BIOS to it's factory default. If your PC is older then you will need to contact the manufacture (or a local non big box repair shop) and get a new BIOS ROM chip.

Hi, i was wondering if anyone had any advice.

Last night i updated my bios (ASUS M2N4-SLI), unfortunately during the update the power went off in the house when i boot now nothing happens, the keyboard and mouse are not even booting. There is power to the motherboard but i can?t get a boot screen or anything, is there any way that i can sort this out?

many thanks

A:BIOS update went wrong, need help please

Unfortunately there is little you can do if the flashing has failed. If the motherboard does not POST, you are most-likely looking at a paperweight. There may be a bit of hope if your mainboard has a chip socket (meaning you can physically pull the BIOS chip) but most are soldered right to the PCB. If you can remove the BIOS chip, you can send it to BIOSMAN where they will replace it and reflash the corrupt chip. I've used them before, it's a very good service.

As far as soldered goes, I'm afraid that's tough luck. Replace the motherboard.

Hello,This is my first time on a forum and I have no idea what "location" to select for this type of issue.  I will try to make this short and simple.  There were a bunch of updates from HP, one of which was a Bios update.  A bunch of others had issues updating.  Ever since then, my wifi keeps dropping, when my service and all other devices are fine.  I try to restart and it hangs there for hours, so I have to hold the power button to shut it off and turn it back on.  When I close my notebook, it will not go to sleep, hibernate or anything I set it to.  Instead it shuts the screen off, hard drive sounds as if it is still running and the computer heats up and power button light stays on.  Again, I have to hold the power button do shut it off.  I have a Windows 10 HP 14 Pavillion was advertised as windows 10 ready, so I don't think it is that since I did that update in July and this just started happening after the bios update.  Is anyone else having the same issues?  Any suggestions to anyone who may have resolved them?  

A:bios update gone wrong

 You could try a BIOS rollback to previous version.  1-Immediately after powering on start tapping the Esc key.2-When the menu appears, tap F2 for System Diagnostics.3-In the list of items will be BIOS or Firmware Management.Use the arrow key to move down & highlight it.Press Enter key.4-You should now have a Rollback BIOS option.Use arrow key again to highlight and press Enter key.

Well I've seriously stuffed up, I'll give you the long story so you get all the information

Well after I installed my 8800GT, I began having stuttering problems with a game, ut2004. Others had the problem and most say its a driver issue and will be fixed in the future, someone wrote to nvidia support and they suggested updating bios, chipset and getting a patch for the game, so I updated the chipset, 945p, easy then I went to update the bios, after downloading bios 3.7, a command prompt came up with lots of settings and commands and warnings, so I decided I'd play it safe and just do the msi live update. So I installed the msi update and its first update was to update my bios, as it finished it restarted my computer, everything seemed fine until my computer wouldn't go past the original POST page, the one with the motherboard logo on it. No beeps sounded and pressing tab or del opened a black page that says

hi --

i'm trying to fix my parents' pc (a gateway 507gr) which has been really unstable & unreliable for a few months. windows wouldn't boot properly, windows reinstalls wouldn't work. it'd boot into the bios ok, but that was about it.

in desperation yesterday, i decided to upgrade the bios, hoping to have a good foundation for reinstalling other stuff. i downloaded the files from intel's site (the board's a d915gag, with a p4 processor with hyperthreading), and did exactly what it said. now things are far worse than before.

intel gave several sets of directions for flashing the bios. the least invasive was to make a cd with this bootable .iso file, put it in the cd drive of the target pc, and boot it up. it did boot under that scenario, but instead of anything resembling the screenshots they showed in the instructions, it said something about the old bios id number, the new bios having a different number, and trying to install it, and then it went immediately to a c: prompt. for a few moments, the pc made these really quiet noises -- not hd sounds, but something somewhat similar (almost like sci-fi "electronic" sounds), but nothing ever happened. it wouldn't even boot into the bios after that.

another method intel gave for flashing was to download & copy this .bio file to a cd, put in into the drive of the target machine, and boot it up with the bios configuration jumper off, to force it into recov... Read more

However on the official HP website the only operating systems available were XP and Vista. I saw that the Vista BIOS was quite recent and thought that the BIOS might work for Windows 7 (my current OS) as well. Since I've flashed the new BIOS my PC can't connect to my speakers at all, or make any sound. It's also running extremely slowly. I've looked up ways to try and roll back the BIOS but nothing comes up, and I can't seem to download the old BIOS anywhere.

Unfortunately? if something went wrong during the BIOS update, then you will not be able to solve this without an help from an ASP technician?

Hopefully the BIOS ROM module is not damage?
In worst case the mobo is damage but maybe it?s not damaged?

However?. You have to get in contact with an local ASP and should ask for further handling!

SupportAssist selects the E5530 version of bios update, which fails to install.
Workaround is to to manually select and install.
Also does not seem to be able to actually install the chipset update it claims to have, as the option will re-appear the next time SupportAssist is started.

You could try reflashing it with the correct one if it will get that far. But it probably wont even boot to floppy now... The only way I can think of is to remove the BIOS chip and reflaash it in a programmer

Thats exactly why I never flash a BIOS unless its absolutly needed.

bought this recently, and must say that i am pretty pissed. i did installation of windows 7 on it and it worked fine for some 10 days till it got BSOD cause of bad system info and couldnt even load into windows. only solution was to reinstall. i did fresh install and i got BSOD with fresh install after only few days. checked internet for solution and saw that you could select windows 7 os in bios for optimized settings that should prevent BSOD. but no option for windows 7 in bios. only for win 8 and other OS. i thought ok, i will just download latest bios and flash it. but what happened when i downloaded bios (a2cn38ww) from support page?i got this message "your machine does not match with this bios". so does anyone know where i can actually  download correct bios, or how to contact lenovo support so they can tell me where to download bios?

Hi Rodrigovhn,
 
Welcome to Lenovo Community Forums!
 
I?m sorry to inform that Lenovo B430 Laptop is only compatible with the Celeron processor range as Ivy Bridge new technology the Motherboard/System board will not be compatible with the normal working of the computer, this is the reason the BIOS update is only available for Celeron processors only.
 
Do post us back for further queries.
 
Best Regards

Hi. I have a SL-510 Laptop, and I did a full re-install of windows. The machine is still very slow in the start-up process. On an other machine I updated the firmware (BIOS) and that really sped up the start-up time.I want to do the same ting with this one, but it is not possible to get in contact with Lenovo. After typing in my product, all I get is that this machine no longer has warranty. There is no option to go from there, so it all ends in a loop. If I click Drivers and Downloads, I am taken through the same loop. If I click Contact Us, the same loop again. Is it not possible to get drivers and stuff even though the warranty has expired???PLEASE HELP
