FYT provide a range of motherboard, base Android and some default apps.

Resellers add screens and components.

Some resellers use the public NOR MCU, stick on a screen and do very little else.

Other resellers do a little more and some do a lot more.

Mekede employ hundreds of staff. They have dozens of pick and place machines that add components to boards. They make software/apps, modify their own MCU, mould/cast their own rear casings, they do branding, and provide (poor) customer support.

There is a big difference between Atoto, Teyes and Mekede head units.

The difference in components and audio quality between my cheapest FYT unit and my most expensive FYT is night and day.

My newest Mekede is not a 116 YIN MCU.

The Navifly unit being discussed isn't even an FYT board.

You're welcome to your opinion, but I disagree.
[FYT Android Head Units] marchnz:
Agree to disagree, the above is not quite correct. Mekede is a made up brand and I seriously doubt hundreds of employees. Teyes say the same.

You actually prove the point - newest is not 116. Exactly, they sell all number of types including non-FYT.

This factory-sell model goes back years, predating mtcb and wince units.
[FYT Android Head Units] j0hn83:
Resellers slap a label on an item and reship it.

You're entitled to your opinion. I disagree.

Feel free to waste your time all day correcting me every time I give my advice or opinion to others but you won't change it.

Some people want a bit more advice about picking an FYT unit than "they are all the same". They most certainly are not.

Just get on with your day.

I also still use PX6 in my main car, working without issue. Mind me asking what do you expect more from your old PX6 ?

UIS7862(s) FYT are popular choice, I don't have one myself, but u'll find a lot of posts and review about it.

HCT Qualcomm 665 (Dasaita G12, Eonon, Xtrons, ...) can also IMO be a good choice. They took the MTCH framework (PX6) and ported it to (real) Android 12 or even 13 (Eonon). My unit is working great and it's also a good plateform if you like modding. Sadly some greedy resellers overprice it... 😓

"made up brand" doesn't show up at exhibitions (where place costs a lot of money) with a booth which costs another thousands of dollars

View attachment 6081957

I have a chinese friend which attended this show and spoke with them. They aren't "made up" brand.

They definitely don't produce the board but assembly it like @j0hn83 said.
[FYT Android Head Units] marchnz:
The photo youve posted further highlights my point - Dudu auto is another example of made up brand name, they all do it.

Made up brand as is marketing/oem/reseller of factory product.

Assemble as in modify the FYT produced software, box up and market and one of the sellers turn up to trade shows, maybe.

Look, I'm not going to debate this further, you can choose to believe otherwise but this goes way back and hasn't changed.

[FYT Android Head Units] Sparkino:
Thanks for the advice, but I still haven't figured out if you would buy a Navifly NF7 or a Dasaita G12 or a Teyes CC3 2K.....

I can't complain about my Dasaita PX6 but I would like better Bluetooth, a 2K QLED screen and a little more speed and RAM.... I chose those 3 models because they seem similar to me and because they are perfectly compatible with my peugeot 208.

I await other advice or models.....Thank you.
[FYT Android Head Units] marjanoos:
Actually DUDU OS is something which existed as a totally different thing than Mekede. Seems like they have joined forces. Or they want to enter automotive somehow.

But @marchnz have you cooperated with Chinese companies as a professional? Well, I did. Attended those exhibitions in Hongkong. In little different branch though, but still electronics. GPS watches for kids specifically. Very similar case as FYT in terms how it worked.

So there is one company, let's say solution company. You can buy PCB with embedded software from them, but nothing more. You have to worry about gps antenna, display, housing etc.

And there are "watch manufacturers" which assembled those watches in their factories. More likely manufactures. They didn't have to worry about the PCB development but only additional things which I pointed up above. There were tons of different watch designs and every single watch had the same firmware, exchangable like in FYT. But you could buy the same looking watch from two different suppliers and they could differ in terms of quality. Because supplier A used better display A and supplier B used worse display B etc.

Every single supplier had it's own factory where all parts were assembled. We had our QA company which checked the device onsite.

If this is what you call "made up brand", then even Philips is a made up brand because little did you know their low end products are actually oems.

This may be the only way to enter the market and some companies are more successfull (like Teyes and Mekede, developing more customized products but still based on FYT's design board) and some stays on that level forever. R&D is so expensive eventually.

So as a conclusion, I don't agree that Mekede or Teyes are "made up brands" which only place their stickers on ready devices. Obviously I haven't been in Mekede's factory but I have chinese friend who is able to go there and inspect.
[FYT Android Head Units] marchnz:
Once more - FYT manufacture FYT units. Mekede also resell ts10 and other junk. https://www.mekede.com/video

I'm sure they all pick and match the level of quality of components to their requirements.

Dudu. Kanged firmware for FYT devices: https://xdaforums.com/t/new-os-coming-for-fyt-devices-dudu-os.4652452/ Great name, but "IDOING" is my favorite.

I'll leave this here.
[FYT Android Head Units] j0hn83:
I posted that list about 6 hours ago. What does it prove? 😂

They are real companies, not "made up brands". They do more than buy someone else's head unit and resell it. The motherboard and OS is made by someone else, which is how thousands of products in the tech sector are made and sold.

Laptop manufacturers sell devices running Windows, with hardware made by other companies, assembled, packaged, marketed, warranted and shipped by the seller. No different to some head unit resellers.

I'm well aware how the FYT distribution chain works. That doesn't make companies who sell them "made up".

Your arrogance is astounding. Nobody needs to "believe" your opinion.
[FYT Android Head Units] marchnz:
You missed the post above yours. Also "list" source is that unmentionable site starting with 4, and is likely your source is too.

Re. "Made up" - another member asked about this....

Here's terms for clarity - two reasons - often short lived brand names sold by many different sellers reusing the "brand" and also shorter than repeating "poorly translated, nonsensical or ungrammatical use of the English language by native speakers of other languages." I could make fun of seller names like "IDOING" (as in what [ I doing] buying this garbage) but I don't. Honest, I'm not IYING about it, I'm [Joying] you. Don't get xtrons at me.

Seriously for a moment, if you find a reseller [type 49] NONAME, I want it for my collection.

You don't have to believe anything I write and you're welcome to ask clarifying questions. Hopefully above terms clarifies and we can leave this here without intervention.
[FYT Android Head Units] j0hn83:
You also wrote

They have been selling head units to the Chinese domestic market for some time, successfully.

Their Chinese name is Dudu Liangshang. They have chosen to brand themselves as Duduauto to the international market where they are just launching their 1st product.

Just because the name Dudu sounds stupid to you and you feel that it's made up shows ignorance. It isn't made up, it's just a Chinese brand name translated in to English.
[FYT Android Head Units] surfer63:
For what it's worth:

Resellers or manufacturers is not so important to me as long as they deliver service.

The whole world exists of manufacturers of semi-finished/semi-manufactured producs and finished products (and every phone manufacturer wants the same Snapdragon 8 V2 and assemble a phone around it).

I myself work for a 25.000+ global chemical company who only create half-products to be finished by "the end market" and we also get semi-finished / semi-manufactured products/ raw materials from our suppliers. That is how the world works and there are many buzz words for this entire value chain.

AliExpress and Alibaba show company profiles.

Let's for example take Mekede: 16 R&D engineers, 12 QA inspectors, 13 years in Industry, annual output ~400.000 units, floor space 3650 m2, etcetera.

Is that 100% true? I don't know, but I chose to believe it.

So for me it is simple: Only chose from the big brands (big resellers) and not from those anonymous, NoName resellers who indeed do nothing more than only assemble and resell without any support.

8~10 years ago quality was sometimes dramatic. Now that the Chinese car industry is growing fast some of those resellers are starting to deliver their products to those car manufacturers (DuDu to BYD for example).

Edit: And in the past I mentioned it twice: My brother had an 1800 euros Pioneer and had to wait for over a year for a bluetooth fix that allowed him to use his phone again with that unit. So what is service?
[FYT Android Head Units] j0hn83:
My made up brand reseller has an extremely active telegram channel with developers talking to us, releasing weekly betas, fixing bugs, implementing features on the fly.

OTA updates now working.

Strings.xml translation files are freely available for the entire OS and launcher. Any submissions received 24 hours before deadline appear in that week's next firmware.

It has much less silly CHEnglish translations.

But of course all of this is made up. It's really just a few guys putting stickers on boxes.

I also chose to believe it. They have many videos of their factory/offices.
[FYT Android Head Units] marchnz:
The posts have a language of a seller. They all promise great things, support, but the reality is very different.

I often ask the question on the forums 'what does seller suggest when contacted for support'. The answer, and lack of support is what drives xda membership. A quick check through the forums is all that one requires to corroborate this point.

No legitimate "brand" engages in scams, such as advertising devices as Android 11, when they are not, with wonderful development focused on perpetuating the scam by development of fake software switches to turn on "Android 11". (e.g. Mekede).

Legitimate business address decade old fundamental hardware design flaws such as the incredibly wrong design of the internal microphone connected directly in parallel with an external mic input (although this one might actually be properly addressed.) or deleting Google contacts (years old bug, which DUDU have just reintroduced "The downside: issue with Google contacts is here. I didn't have any issues before with mekede's fw and yesterday I found out that my google contacts are gone.")

Legitimate brands also don't misrepresent their business, when the reality is they are a single digit drop-shipping operation (e.g. "teyes australia") with colorful misrepresentations of their offices, operations and promises support.

All of these negative points aside......

******************

Look, I say lets forget about the promises and marketing - I think enjoy these device as a hobbyist level device, engage in buying with eyes wide open, lowered expectations, know what you are buying and with one basic rule to always ask the seller for screenshots of the device 'system information', negotiate the best price and expectations will be met.

They are a lot of fun, and I for one are very thankful for the variety of devices from various sellers. It's hugely entertaining and functionally ALOT better than the big brands official Android Auto.

My two "Mekede" FYT uis7862 Type 116 sound amazing, probably the best sound out of a headunit I've owned, and with BLE, connects to my V1gen2 - I couldn't be happier. Miles better than my last MTCD "joying" (which had a sticker placed on it as "brand."

*******************

Can you tell us more about the telegram channel, what's being developed and so forth?

https://shop.samsung.com.cn/product/SM-S9280?cid=cn_paid_ppc_baidubz-PC_samsung_none_estore_text_20240301_miaoshuwenan1_pfm

According to the offical site of Samsung in both country, they have almost SAME 5g bands except N79 which my carrier doesn't use.

However I can't receive 5g signal here while my old S20+ （Korean version）is able to, and the speed test shows it can run at 250-300+Mbps at where I sit.

I've trid:

1. Play around all the settings available in setting, including set all bands on in *#2263# setting, doesn't work.

2. Directly flash firmware of S9280 (which is the native version of S24 ultra in China) in Odin, since the bootloader haven't been unlocked, failed of course.

Now my question is:

1. Should I try to unlock bootloader in order to flash S9280's firmware? Coz I'd asked two users in China who also bought S928B, they both said they can receive 5g signal after flashing S9280's firmware.

2. However, even if I succeed of doing so, I gonna lose Google AI function becasue in S9280 firmware it has been replaced by some "dumb" apps which are far worse than Google ones.

3. Is it possible to unlock bootloader, flash only CP or CP+CSC file of S9280 firmware and use S928B firmware files for the rest coz thier hardware are almost same? Will I totally brick my phone by doing so?

4. Should I skip <3.> and just go ahead with flash costom roms such as Dr.Kertan's, will it solve my problem?

5. Any other methods I should try out?

Thanks a lot if any expert here would help.
[Samsung Galaxy S24 Ultra] Lodix:
I don't think it has anything to do with it, but update the Google Play Services, you still have the July software.
[Samsung Galaxy S24 Ultra] AdarXu:
I've took your advise and updated Google Play Services, still no 5g sigal received, see in the picture below. I don't think the sigal problem has relationship with Google Play Services but I tried.

You don't need to unlock the bootloader. Try installing the official Samsung HK S9280 firmware onto your SGS54U. See if that works.

Alternatively, you can try doing a hard factory reset on your device

Try booting your device into Recovery Mode, wipe the cache partition and do a factory reset there.

I'd tried that, I also tried to flash both CSC+CP only/BL+AP+CSC+CP files of "OPS, S928BXXS1AXBG" which are download from SamFw, after that I wiped cache and did factory reset in Recovery Mode.

And the strange thing happened---no matter what I do, in my phone software info, the service provider software version stucking the same as my post in #1.

I am sure I successfully flashed with Odin and wiped data and did factory reset in Recovery Mode, and something "has" been changed since in the google play system update has been down grade from Feb1 back to July 1,2023.

I don't know what am I doing wrong, normally when I flashed CSC+CP of other region, at least the service provider software should be changed, isn't it?
[Samsung Galaxy S24 Ultra] AdarXu:
I was flashing my S928B/DS which bought from Singapore with Odin, the origin software info are:

View attachment 6081570View attachment 6081571

My goal is to get 5g sigal in China, I guess the reason why I can't get 5g signal is the carrier's limitation in CP or CSC files (the phone itself has the 5g bands I need which are N1, N8 and N78).

So I tried S928BXXS1AXBG of region OPS by flashing and CSC+CP only / BL+AP+CSC+CP files together of "OPS, S928BXXS1AXBG" which are download from SamFw, after that I wiped cache and did factory reset in Recovery Mode.

And the strange thing happened---no matter what I do, in my phone software info, the service provider software version stucking the same as before, still the SIN one.

I am pretty sure I successfully flashed with Odin and wiped data and did factory reset in Recovery Mode, and something "has" been changed since in the google play system update has been down grade from Feb1,2024 back to July 1,2023.

Then I guess it's because of I flashed the same version(S928BXXS1AXBG ) , so I downloaded S928BXXU1AXB5 from SamFw again, flashed with Odin, wiped cache and did factory reset in Recovery Mode and here it is

View attachment 6081572

the service provider software remains the same as before.

Can anyone help me out with that?
[Samsung Galaxy S24 Ultra] MeltdownSpectre:
CSC won't change like that. Flashing different regions firmwares will do nothing.

You need to insert a SIM card from a country that belongs to the OXM multi CSC used in the S928B firmware.

Based on your previous thread, you are in China, which does not belong to OXM because China gets a different variant of the S24 Ultra (S9280).

You would need to unlock the bootloader and try to get the CSC from the S9280 working on your phone to see if that enables 5G.
[Samsung Galaxy S24 Ultra] AdarXu:
Thanks a lot, your replie is helpful.

Actually that's what I am planning to carry out. I am just looking for some possiblility of not unlocking bootloader however there seems to be none.
[Samsung Galaxy S24 Ultra] iceepyon:
From what I see in your Odin screenshot, it seems like your OS install has failed.
[Samsung Galaxy S24 Ultra] nguyenlucky:
No you can't install official S9280 firmware on S928B, don't waste your time. Try changing CSC to XSP (Singapore unbranded) or other CSCs like INS, XXV, THL, etc. Yours is currently SIN (Singtel or some carrier).

CSC change is not just for call recording, Spay, spam ID, it's also related to network config (4G, 5G and their features)

There is also a possibility that your phone model/IMEI isn't whitelisted by the carrier, in that case, talk to their customer service. Samsung won't do anything since S928B is not sold in China.
[Samsung Galaxy S24 Ultra] nguyenlucky:
Because both OPS and your current CSC belong to OXM multiCSC. Flashing firmware between CSCs within the same multiCSC will not do anything. You need to use Samfw tool to change CSC.
[Samsung Galaxy S24 Ultra] AdarXu:
Thanks a lot, I gonna try this insead. Your answer is so helpful. And from the info I gathered in China, if I unlock BL I can flash S9280 firmware with S928B with no problem, but just gonna lost all google apps and ai function which I don't want to, just post here FYI.
[Samsung Galaxy S24 Ultra] nguyenlucky:
It's a custom ROM though, not official ROM. And you lose Knox permanently so be careful.
[Samsung Galaxy S24 Ultra] sealed:
According to the information from Coolapk, I find several solutions that may help, but I cannot test.

First of all, you cannot flash 9280 ROM because it's not the same model. By unlocking BL, you can flash unofficial 9280 ROM. So, the only choice is changing CSCs or carrier policy without ROOT.

The reason why China cannot use 5G is because international model only support 5G NSA. China mobile still have 5G NSA in big cities, other service providers only have SA. Although 928B have bands, there is no operator profile to enable SA and Vonr.

Solution:

1. Changing CSC. INS maybe can use, one person said ok, the other not. THL have SA switch and can use *#2263 to force SA, but one person said useless. WWA or WWD maybe can help but cannot OTA.

2. By using QPST, there is an exception in Carrier Policy.xml to enable SA for an India provider. May you can replace this file to Chinese provider and delete band cap prune to support band combos. The method is similar to unlock 3CA.
[Samsung Galaxy S24 Ultra] Lodix:
I don't know if I understood you well, but all versions of the S24 ( and any 5G phone) does support 5G SA. It is just the normal and real 5G. I have access to 5G SA in Spain.
[Samsung Galaxy S24 Ultra] sealed:
Of course, all versions of S24 support 5G SA. I mean if a sim and a phone are from different regions, the phone will not know what type of 5G that service provider provide, so it will load default configuration file which does not enable SA feature to ensure compatibility.
