Hi.. newbie here need some information and brightness from all master here. After some time I using a dna chip now its time to try SX Chip. Really impressive about G Class and consider to taking one.
But there are some thing bothering me....

1. The problem is: I have a very acid sweat (I mean when I use jewelry like gold or silver, they will turn dark very quickly) and so also my several mod are having damage paint in 3 or 4 month, the only my last mod is an epetite dna 60 SS because there is no paint and only wood) the question is: Is the material of G class is good? I consider to take a black carbon but I has been thinking about a frame which ahve a grey paint. I also intresting about brown leather coffee because it has SS frame and feel classy I like it so much but the leather.... is that will have a lasting colour? I have no experience using a leather? And can be the leather be replaced? From what I heard if the material contact the liquid it will very quickly damage.

Will be very glad if someone can give a brightness. Thx

The finishes are anodized and quite durable but not indestructible. The wrap, CF or leather, is coated with a rubberized layer that should prevent any loss of color. You can also get fitted silicone covers that fit quite well to add more durability.

Reposting this, just in case anyone wants the old 6.6 firmware (I posted this awhile ago). This is the beta 6.6 firmware with the custom wallpaper stuff. Been using it for awhile. It has been working fine for me, one thing to note, if locking the device, you now push the joystick down to unlock the device.

To be clear, this is not the new 6.6 firmware, this is the beta they released a month ago. I will modify the zip when the official 6.6 comes out so that folks dont have to go through yihi's terrible website and awful download speeds.

The new firmware will be 6.7 and while the instructions page (link at the very bottom of the post) show 6.7, it is not yet available.

Read the instructions carefully because, as all yihi firmware updates for the G class have been so far, it is a wonky installation process.

I zipped up the 05192017 driver (you MUST install this, you cant install with the previous version, there is a two step process and the old version will not allow you to perform the second step). Also included is the 5.5 and 6.6 firmware updates, in case you need to roll back.

Follow these directions explicitly, otherwise, you will have issues.

After you have installed the SXI software...

Make sure the SXI software is closed and your device is unplugged.

Unscrew your atty. Launch SXI software. Plug in your G class. Go to connect in the SXI software and make sure it sees the device as connected. If yes, go to upgrade, click the upgrade button. It will say you need to select a file. Point it to the 6.6 firmware update (this is the file that is 4 mb in size, should say 6600 in the file name). Click update again.

Once the update completes, your device will say Update UI....

Unplug your device and close the SXI software.

Launch SXI software. Plug in your G class. Go to connect in the SXI software and make sure it sees the device as connected. If yes, go to upgrade, click the upgrade system button. Point it to the 6.6 firmware update (yes, we have to do this a second time). Click upgrade system. This second update will take significantly longer.

If you have any issues, included is the 5.5 firmware, I do not know if you can simply roll back once 6.6 is installed. I do know that if you have any issues prior to the second part of the update process (where it says update ui), you can roll back.

Reposting this, just in case anyone wants the old 6.6 firmware (I posted this awhile ago). This is the beta 6.6 firmware with the custom wallpaper stuff. Been using it for awhile. It has been working fine for me with one rather annoying exception, if you lock the device, there appears to be no way to unlock it without doing a battery pull (I might be missing something tho).

To be clear, this is not the new 6.6 firmware, this is the beta they released a month ago. I will modify the zip when the official 6.6 comes out so that folks dont have to go through yihi's terrible website and awful download speeds.

Yes your missing something when unlocking. With it locked, press three times on power button, a lock should appear. Then flip the joystick down.

I have been wondering how to get out of lock as well with 6.6, I do the same as you and just pull the batteries.

There is a pdf on the yihi update page as well that explains the process and tells you how to do the wallpaper.

I like the update besides the lock feature though. The wallpaper is cool to play with, still rocking the hot suicide squad chick!

I just updated the post, I didnt realize they changed the unlock procedure. I also added some useful links as I never can seem to just do a Google search to pull up Yihis site, they always take me to some sort of link farm page...

Awesome, thank you.

 

[littlewierdo]

For completeness sake, I just added the android apk and all of the previous updates to the zip as well. Not sure why anyone would want them, but why not...

 

[VapNMirrors]

Took a little getting used to but I like the childproof lock, annoying but, well, childproof.

I just like that there are really no huge issues to speak of other than a wattage readjustment that is always required when I rewick. Im vaping on an Aromamizer Plus dual coil setup, 40 watts currently, but it never fails, next time I rewick, Ill have to dial it up or down.

Also, it seems the material cannot be set to kanthal even in wattage mode...

First rule of G Club - Should always lock cold, kanthal or otherwise (also any Yihi). Perhaps your problem?

No such thing as material when you switch to power mode. It's just calculating firing voltage from the resistance it sees. There's no TCR value in the math.

If you dry burn when you rewick then the coil resistance can drift a little too. Hence first rule.

 

[littlewierdo]

Not exactly correct, yihi uses a floating resistance. While you can lock the resistance, the mod will change the locked resistance. The material shown on the screen cannot be set to kanthal. In wattage mode, it is not using a tcr value, I get that, but, the material type should still be able to be set to kanthal, or not show a material type in wattage mode as this is not relevant.

I understand resistance drift, this is different. Having to fire a 0.3 ohm coil at 55 watts, then rewicking (I know how to dry burn and clean coils) and having to drop to 40 watts because the vape is significantly warmer is bigger than resistance drift...

The finishes are anodized and quite durable but not indestructible. The wrap, CF or leather, is coated with a rubberized layer that should prevent any loss of color. You can also get fitted silicone covers that fit quite well to add more durability.

It's not anodized as it's not aluminum, plus anodizing doesn't look like paint. I've been able to chip the paint off w/ a credit card which is impossible w/ anodized aluminum, there's zinc alloy underneath.

Anodizing can only be removed chemically or with a whole lot of sanding. Anodizing is like applying an oxide with a current, since zinc resistant to oxide its harder to do, requires a different type of current etc. afaik it hasn't been done w/ mods. The "SS" looking ones have some kind of shiny paint on them.

Yes, I've seen it adapt it's lock but only after a big change in base resistance- like a different coil entirely, not exactly floating. Still best to lock because you're telling it your at the compensate temp at that time.

I agree that it should not display the material when in power mode. That's a bug on the first two wallpapers that they should fix.

If you are having to adjust 40 Watts that's not right. It's a bad connection in the atty or a bad mod- that is not normal. Are the resistance "locks" even close? I would exchange the mod.

I stand corrected. Call it "anodized looking" It has not chipped like paint but slowly ground away on the bottom as though it were anodized.

The atty is fine, works fine on other devices. Older firmware seems to have less fluctuation in resistance. As to the base resistance changing after it has been locked, Ive seen it change by 0.01 ohms so it isnt necessarily only when big jumps happen.

Im not sure if locking resistance is a thing of the past, Ive been looking into this, it seems this is a feature of other devices called 'smart resistance', where the device attempts to adjust the resistance on the fly. The most new devices even have smart wattage, where the device attempts to set a base wattage that is appropriate to the resistance on the device.

It is working fine for me, I just have to make sure to check the resistance when I fiddle with the atty.

By the way, the new beta firmware is up, I almost have it downloaded, Ill add it to the zip file and put on Google drive. The 80 mb download has taken over 3 hours...

This is what anodized aluminum would look like, like it's part of the metal now, & the finish shows through

like here's brushed

polished

I used to help a guy do aluminum anodizing and also refinish mods/remove dings/scratches etc. Anodized is probably the toughest finish there is, I've seen it hold up to sandpaper (for a little while) and gouges about 1mm deep. It doesn't rub off. One of these days these chinese will figure out how to paint a mod and that will be the day, but it hasn't happened yet.

Hey guys. Been following this thread now for a while even got the instructions for the firmware update here but haven't thought of becoming a member until a couple of hours ago lol.
Been using my g class for over a month now and I've been pretty happy with it! Uploaded a photo of my setup with it. P.S the ability to add your own wallpaper rocks!

Ive made the firmware and driver available on my google drive account (link above), Yihi makes premium ecig devices but apparently cant afford premium web services (Squarespace, Amazon S3, something??) - there are plenty of affordable hosting services that offer faster than (literally) dial-up speeds...

Only English versions are included.

Included
Latest driver (2.3.1)
Android apk file - official release from the play store (1.1.0.8) & older version from Yihi's website (1.0.7)
All of the firmware updates I have (4.0, 4.3, 5.5, 6.6, and 6.7).

Special note for the newly released 6.7 which was released 6 hours ago, it has a readme file that was included, please read it. There are two firmware update files, you will need to look at whether your chip is an A chip or a J chip, you can see which it is in the driver software.

The updates are cumulative, meaning, you only need to install the latest version. Below are all the changes since the factory release.

Link added above. Note that Yihi put a duplicate update file in their zip. I didnt include both, since they are duplicates...
