@Lost_N_BIOS Hi,
the programmer and the cable arrived yestarday. I would like to try to dump the content of my bios but first i've a (stupid) question.
My bios chip is soldered on the motherboard so i will use the cable to connect it to the programmer. During this operation should i disconnect the laptop battery from the motherboard or i can leave it connected?

Thanks
Mattia

@tmbt - It's not a stupid question, it's a good one! All systems are different, some may need the battery or power connected, others may work fine without it.
I would remove battery and power at first, then if it's not working no matter what add battery, then if still not working plug in main power.

What BIOS chip are you working on? Please check with magnifying glass and flashlight if you need to

Here is guides for using these, first one has plenty of images so you can get it all connected properly
[GUIDE] Flash BIOS with CH341A programmer
[Guide] Using CH341A-based programmer to flash SPI EEPROM
[GUIDE] The Beginners Guide to Using a CH341A SPI Programmer/Flasher (With Pictures!)

Please do not write anything until you're 100% sure your dump is verified and valid. Valid means your opened it in BIOS tools and it looks similar to a stock BIOS, and you checked in hex before that to make sure it's not all FF or 00
If you are not sure how to check this out, upload your dumps and don't try to write anything until someone says dump is proper and it's OK to write.

Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!
If you appreciate my efforts and are willing to donate to help improve my hardware, gift cards work for me (Amazn, NuEgg, eBa) - send me a PM

@Lost_N_BIOS This is a never ending story .. I've connected the programmer and then the cable to the chip on the motherboard. If i try to read the smaller chip (i'm referring to a picture i sent you on page 2 of this thread) i can dump the content of the chip but it 's not the bios . After some Kbytes of 00 there is a reference to a Texas Instrument DP controller or something similar.

The problem is that the other chip is not thick enough to be catch by the pliers so i 'm not able to dump that one.

Is this possible ?
What can i do ?

EDIT :
Seems like the W25Q64FW is using 1.8v instead of 3.3v but i don't have the 1.8v adaptor. Is this the reason why i can't read the chip ?

@tmbt - As mentioned that smaller one is probably EC. Show me images of the entire board, that larger one above the tiny one, doesn't look like BIOS now that I look at it again (it looks surface mounted like memory, instead of having legs)

And yes, if BIOS is W25Q64FW that is 1.8V and you'll need adapter to use with the programmer, like this

Sorry we did not notice this earlier!!

@Lost_N_BIOS ,
Hi attached you will find all the pictures (EDIT .. pictures are in two posts later) i made this morning on both sides of the motherboard. I cannot spot anything similar to a BIOS chip but i hope you will be more lucky !
I was able to find a 1.8V adaptor here in my city without ordering over internet so i'm ready for everything now ..

Please let me know !

Thanks
Mattia

UPDATE: i tried to dump the content from some chips on my motherboard but the only one detected and readable is the first one. All the others are too thin and the clamp cannot reach the "legs" of the chip in my opinion.

Heeeelpppp!!

@tmbt - reat you found a 1.8v adapter locally, that's pretty cool it's even possible to find one without ordering (Are you in China?) I thought you already connected to W25Q64FW before, no?

Please put all those in a zip folder and upload somewhere, thanks. Once I can see all the images I will let you know if I can find. Sorry don't want to look at them like that, I'm on limited internet and there's no reason for all those not to be zipped

@Lost_N_BIOS No i live in Florence (Italy). I was going to orderning it on eBay but then i noticed that the seller was from Florence too so i called him and arrange the pickup at his home ...

About the W25Q64FW no i wasn't able to connect to it. I was only able to connect to the small chip (which is only 1MB so i guess cannot be the bios) but inside the dump there is reference to Texas Instrument Controller. That's the only chip i was able to connect. All the other chips i tried seems to be too tiny and the clamp doesn't reach the pins (at least i think this is the problem).

Here are all the pictures in a zip file : http://s000.tinyupload.com/?file_id=03192282629654589523

@tmbt - That's cool you were able to locate so easily! Yes, the 1MB isn't BIOS, probably? Not sure, send me the file so we can confirm.

thanks for images, I will look them all over and let you know what I think tonight. Pre-tonight, I checked and these are very small resolution, can you zip larger ones? If these are only size you have it's OK

* Edit - from what I can see, yes, looks like the one above the one you already dumped is the BIOS.
If you cannot get clip onto that, and you aren't good at soldering, I think only way may be similar to what's done here, but we'd need to find exact method for your model
Dell Inspiron 5520 BIOS recovery help needed

Tonight I will try to find schematic and see if I can find method for your system.

@Lost_N_BIOS : No i'm definetly not good at soldering so i would like to avoid that. I tried more than once but i cannot get the clip on the chip. I think it's the chip because from reference manual it is 8MB size and the dumped bios i made was 8MB. How could be the 1MB chip ?

Here are the HiRes pictures (50MB totally) :

http://s000.tinyupload.com/?file_id=60421646517801435154
You'll need all the 3 files ...

About the link you posted i've read it twice but i don't have the slightest clue of what you're talking about in that thread :)

@Lost_N_BIOS Ok seems like i've bricked my laptop .I've found on a chinese site some script to unlock the bios and modify DVMT to 64MB. I saw the scripts were using H2OUVE (same version we tried at the beginning of this thread) and also they were doing some offset check before modifying to see if the bios version matched so i've used them but now i've black screen at boot and the laptop switch off itself after some keyboard flash.
Here is what the scripts did :

Here something went wrong because if you see the patched text too many bytes are changed.
After that at the reboot i've a black screen.
The only positive thing is that i've a bios backup i've done first thing before doing anything else using ftpw -d backup.bin . Using that i can confirm that the chip who has the bios is the w25q64fw because during the dump ftpw reported that chip has the bios flash chip.

What can i do now ?

I was not too worry about the script because i thought we reached the conclusion that using H2OUVE was useless but apparently the first script worked to unlock the bios because the second script was able to write where i wasn't able before.
None of this is your fault obviosly but i would be really happy if you could help me solving this (if you think it's possible).
Here is the dumped bios just in case :

#42 | RE: [HELP REQUEST] - Modding Huawei MagicBook BIOS datum

Sat Mar 09, 2019 11:17 am

Sorry, I was not able to find schematic, only thing you can try is email Huawei and ask for schematic and how to program SPI via KB ribbon or other method.
That's what I linked on that other thread, some systems there is a method to write to BIOS through the keyboard ribbon cable, like SPI header pins on a motherboard. This method or similar probably on your system, since main BIOS chip is SMD (Surface mounted) instead of SOIC type chip like the little one.
And yes, sorry, you'd have to be really good at soldering to do what I was referring too. You'd have to solder 8 wires to the very end of the traces coming out from under that chip, then solder pins to those wires and insert to the programmer.
Or remove that chip with hot air and replace it with a regular BIOS chip instead, pads should be same/similar length there to allow either

Not sure what you were doing up there with the scripts? Did you at least translate it all and make sure it was for your model? You mean too few bytes there at the end, if before first and after later. You didn't notice the bytes missing before flashing?
Since it's bricked, nothing I can do looking into any of that would help anyway. Sorry to see this happened to your system!

What is this dumped BIOS at very end? Did you get the clip connected? If you can get the schematic for the board I'm sure you can program it via ribbon cable as I mentioned, hopefully Huawei will be nice and send you this info!

The dumped bios was taken before beginning the script procedure so it's the original untocuhed bios. If i ever will be able to remove the chip can i program it using that dump?

About the replace of that chip ... suppose i will bring the motherboard in a laboratory i know and make it remove ... with what kind of chip should i replace it ? Same W25Q64FW but SOIC8 instead of SMD ? Does it exist in that version?

Thanks
Mattia

P.S. I noticed there is a thing called mini grabber smd .. basically it's a mini clamp to grab a single pin of the chip ( I would need 8 of them) . Do you think they could solve my problem?

Yes, you can use that to insert into a full dumped BIOS and then reprogram (Since the dump is BIOS region only, unless you dumped entire BIOS)

Yes, replace with W25Q64FW or W25Q64BV, and yes they come in standard SOIC8 (this is the normal package), you can get on ebay for only few $$, https://www.ebay.com/itm/123223245280
I believe it will fit there, since the trace landing pads are usually sized so various chip mounts can be placed in same location, but you can't be 100% sure until it's removed.
Anyone that knows how to remove chips via hot air and does BIOS rework, or motherboard rework, likely has this flash roms already in stock (I have a pile of all kinds and I only repair boards at home)

Those grabbers you linked, you can try to see if they can grab anything, but if it's actually SMD chip there is nothing to grab it's just ball soldered underneath the chip (Like memory stick chips, look at those and see if you think this is same)
From what I can see there is no pins there, only flat chip and it's soldered underneath (SMD), what you see coming out of the sides is the landing pads on the board where actual SOIC8 type chip legs would go.
Look with a magnifying glass and see if you see legs on the side, or only the slick silver pads on the board and all connections are underneath the chip like a regular stick of memory

@Lost_N_BIOS Thanks for all the info. On monday i will decide how to procede. What is not clear to me is why calling the product mini grabber SMD if they are not SMD compatible ...

I wrote you a PM.

Thanks
