@Lost_N_BIOS
Sent you a couple PM’s and sent over my VARs file. Hoping you can help me unlock my Acer Triton 500 BIOS with this method. Thanks!
my cheap 2666 kit support 3500 mhz intel specs are not the max the northbridge QPI can handle
Hallo sorry i know it has been a long time like less then month looool any way i hope you are doing well i tried like more then thounsed time with my (old clip) so i bought a new clip lets say a better one i was able to read from the chip i have tried a 2 diffrent software and vesion i will include a link down below, mein is xm25qh128 i used EN25qh128 as you told me here is the link : https://www.dropbox.com/sh/pjpn5akz95i7z…B2JSYem-7a?dl=0 can you check if there are correct and can i write it back
@Lost_N_BIOS
EDIT* xm25qh128A
@Saeed_Haidar - Only Colibri dump OK 
Did you get Pomona 5250 clip?
Do you need one of these edited to unlock menu, or you only did this for backup/recovery concerns?
Sorry, it’s been so long, not sure, and I know you can flash in mod BIOS without programmer, so not sure where we were with your BIOS. 
Ohh! I just found your folder in my BIOS, looks like I sent you unlocked BIOS already and it’s not even this same model this thread is about! Now, I see our previous discussion on page before this one too, so you can disregard above now
i bought this one https://www.amazon.de/-/en/gp/product/B0…0?ie=UTF8&psc=1
it work way bettter then the ones comes with ch341a
edit* https://www.amazon.de/-/en/KeeYees-SOIC8…&s=ce-de&sr=1-1
That is same cheap clip that comes with all the CH341A, it will wear out quick too, it’s only good now because it’s new, just like your original was good when new too.
If you want a good clip you need Pomona 5250 + Long Dupont cables with M/F ends.
Hi, I have unlocked 315-52 bios version 1.08 now new version is 1.11 can I update with out opening laptop and kepping unlock?
Is there any benefit to upgrade bios?
Thanks
@zmay2509 - If you update BIOS you will have to dump with programmer again and have BIOS re-edited, then program back in. But ONLY IF you were unable to make flash possible via vars edit and FPT << However, I believe we’re using this method below now, so programmer is not needed!
See post #388, this is how we do it without programmer (so you don’t have to open system) - [Help] Unlock advanced menu on 2019 Acer Predator Helios 300 PH315-52 (26)
So you can update to latest BIOS, then dump vars and biosreg and send to me. Then I will edit vars for you, you program it back in, reboot, and dump BIOS region again with FPT and then test flash it back (will succeed), then you send me that to unlock and I edit and you then flash it back.
Hi @Lost_N_BIOS , I have a locked bios v1.11 which I’ve dumped and attached the vars.txt file. Would be great if you’d be able to help me get this unlocked. Thanks in advance!
vars.zip (34.3 KB)
@zmay2509 - Here is modified vars, flash back using command below, there will be success and errors in long string, reboot then dump BIOSregion again with new name (like BIOSregnew.bin) and then try to flash back, should be success.
Once success, send me your new BIOSregnew.bin file

@Lost_N_BIOS
@Saeed_Haidar - Copy setup from old to new is not ideal, in case they modify or fix something, or change some variable ID to some setting etc, then you are putting in old setup instead.
Best to unlock it properly, it’s only two bytes to edit in setup PE32 body (0xA0E: 70 >> Change to >> 00 + 0xA46: 38 >> Change to >> 00) << Anyone seeing this, his system is NOT PH315-52!
PH315-52 has 4 bytes to edit, and it varies between BIOS version and this is the reason for what I mentioned here (not ideal to swap setup from one version to another)
There is only one driver, all same/same but some are older, but yes, only certain software or ID work with some BIOS.
ASProgrammer 1.41 should work OK too, with the ID above or this one W25Q128FV, I’ve never seen 2.x anything for ASProgrammer, sounds like you have some random edited file or something?
Hi @Lost_N_BIOS - bios was dumped and flashed successfully. Linked below is the new dump. Sorry, I can’t post complete URLs or upload the file since it was over 6 MB. Thanks!

Here’s the link to the manufacturer’s download for this BIOS version (v1.11) just in case:

@odo - here is your unlocked BIOS, program in via >> FPTw.exe -bios -f biosregnewm.bin

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don’t try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)
WARNING *** - This BIOS is user specific! If you are not user odo at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not odo, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!

it shows that it is veison 2.x i do not know either
@Saeed_Haidar - Version 1.41 is latest, no version 2.x ever - https://github.com/nofeletru/UsbAsp-flash/releases/
