some rumors say yes, others say no.... What do you think about it? Do you have fresh news? It will be a shame if htc removes wifi from the touch succesor
if not htc would qualify as being an odd duck because
Qualcomm MSM7200 (SoC) the cpu of nike have onchip
wifi support
http://www.umtschips.com/products/msm7200_chipset_solution.jsp
http://www.pdadb.net/index.php?m=specs&id=736&view=1
so they get wifi for free
I hope you are right Thank you (and "Hi all" I'm a newbie this is my 2nd post )
Even built-in GPS!
if it doesn't have wi-fi it'll be a big FLOP
In the past HTC have disabled some of these "free" features, and enable them in a later revision just so that they make it look like they are actually progressing!

I'm pretty sure that no gps will be in p5500, so say all reports.
But, if they disable (or phisically remove?) built-in gps form MSM7200 why can't remove even wifi to avoid competition with others upcoming devices (polaris, or the new tytnII)? Ok, without wlan will be a flop but technically? Can they remove or they can just disable embedded components on MSM7200?
"or phisically remove"
is not something you can do with something on the cpu chip
of cause they could not connect the legs to an antenna
but it would seem a bit silly imho
understood, so as i mean (and hope)

That is exactly what they did on the Hermes
http://www.htc.com/product/03-product_htctouch_dual.htm
without wifi. This morning was specified, now has been removed such a shame
According to Modaco the Touch Dual had WiFi on the devices at the launch and they are confident it will be there on the devices.

http://www.engadget.com/2007/10/02/poll-does-the-htc-touch-dual-need-wifi/
same news on engadget. I hope so, without wifi I risk to have to buy "iphone" (brrrrrrr) for my commercials instead of this shiny touch
again
"Some of the countries will receive shipments of a particular version of the device that supports Wi-Fi"
http://www.smape.com/en/reviews/htc/HTC_Touch_Dual-rev.html
and pdadb.net sign it as "nike 100".. What does it mean? Also, no trace of 20keys model in any htc site
Given the nature of the recovery partition/os.. I think it would be possible to test out a native armhf environment.. Probably not any performance gains (maybe md5sum?).. but a cool thing to test out..
Doable?
This could greatly improve the quadrant performance on at least "cpu performance" and "disk i/o speed" amirite?
sounds interesting

Maybe CPU performance, but disk i/o speed is I think caused by low bus speeds... or the EMMC interface Asus used for their NAND, maybe it's badly implemented (Samsung and Acer all use the same method, NAND on an EMMC I/O interface, so it's detected as an sdcard, but their method is fast). And maybe improve database read/write (SQL encoding etc)
Well, I do not know if android be compiled for armhf. I was mainly speaking of the recovery 'system'.. fpu performance can increase from 30-40%. This could probably help out software video decode and certain elements of certain games..
Its like the name suggests.. it uses hardware fpu on the armv7.. the curent implementation maintains compatibility with older devices and passes only some fpu instructions to hardware.. its called softfp.. I'd hope most of android is softfp (well actually, hardfp would obviously be preferred - but it wouldn't work with older arm cpus)
Have a look..
http://wiki.debian.org/ArmHardFloatPort
And yeah.. disk io would probably still suck. But as you may or may not know - even a usb3 flash drive, which obviously has capable flash memory of going beyond usb 2.0 bus speeds, fails to reach full usb 2.0 bus speeds on the tf101..
I've said this before.. if you want optimal emmc reads/writes, bypass the middle man (/system/bin/sdcard binary) and write directly to /data/media.. /system/bin/sdcard process chews a lot of cpu when you write to /mnt/sdcard/
I suppose this all done to keep the perms for /data/media conforming to
1023.1023 rw rw r (664)
Also, when a large file transfer is taking place using something like terminal emu.. its best to kill any memory hogs before hand.
kill `pgrep browser` `pgrep launcher`.. don't worry, they'll come back when you're done.
But I digress.
This probably won't work as the proprietary blobs from nvidia/Asus are likely only compiled for softfp
Again, this would be for the recovery partition.

And of course, kernel too. The graphics acceleration blobs are Asus/nVidia properties, but yet we could increase the performance a bit.
About sdcard mount: what if, instead of using that crappy fuse mount Asus wrote, simply creating a symlink: yes, attaching through MTP would be a PITA, and there would be permission problems at the beginning, but with one-two smart services, they can be eliminated. Or remake the sdcard binary, but in a somewhat less performance-eating way, by creating a virtual new device and mounting it?

Asus didn't make it, but they may have modified it. You can see the source here: http://ww.bensonkim.com/system/core/sdcard/sdcard.c I can also look in the kernel upsream and see if there were any significant improvements to fuse that can be backported.

I was talking about their modifications, as yes, they modified it. You might not have noticed, but I did (after playing with a Galaxy Tab 10.1 and an Acer Iconia A500), that the TF's performance is way lower than those two, yet the hardware is 99% the same, or even better (the GTab10.1 bases on the Harmony board, just like the A500, but the TF is on the newer, better performance Ventana board)

I guess its a case of irony, but the harmony board's nand timings appear to be very very easy to tweak.
See board-harmony.c in 2.6.34 - not saying this is a sane solution.. but if I could do it on the tf, I would - within reason. Don't want corrupt writes.

Harmony, if I can say that, was a bit 'more open' in this sense: it had more options to tweak, but just bcos it had the older Tegra2 chipset (AFAIK, ours is the T20 T250 version, while the Harmony board houses an AP20H T250), and was a more "test board".

Yeah, I have a gtab - it clocks to 1.7 with ease and the gpu is just as capable. I don't think it can run the l4t (Linux for Tegra) stuff tho... so its not exactly a dev board.. isn't kind of the same thing? AP20H vs T20 is not like T25 vs T20.
Edit:
http://en.wikipedia.org/wiki/Tegra_2
Erm... harmony may not mean it has AP20H.. as the viewsonic gtab is definately a harmony board

The Wikipedia one is wrong I guess, as the Harmony definitely had AP20H. Point is, it is a slightly different SoC.

nope, you are wrong.
The difference between harmony and ventana is:
Harmony is the nvidia reference board for phone form factor and has T20 silicon revision A02.
Ventana is the nvidia reference board for tablet form factor and has T20 silicon revision A03.
Not many manufacturers make head units to match my car, a 2004 C5, even less with the newer PX5 units. I did find this one,

anyone have one of these Seicane units?
is there any reason to think it's any different than the other PX5 units as far as modding and firmware upgrades?
thanks!
Hello, yes I do have a unit bought by Seicane SELLER.
Seicane is just reseller and you will get all sorts of units built buy other MANUFACTURERS if you buy from them.
In my case I bought a unit for Subaru and found it to be an MTCD device built by Klyde (MCU manufacturer code: KLD).
So as of my current knowledge you won't really know what manufacturer built your unit until you check the system about screen for the real manufacturer. And as a result the devices are no different than the ones bought by any other reseller.
Don't buy from them, they have worse to NO service at all!
I have a broken (warranty) seicane unit, i am mailing with them now for 1,5 month to get instruction how to send back.
They give bull**** answers or ask bull**** questions to keep you waiting, after a while they stop responding.....
I advise do absolutely NOT BUY from them, just a worse and also expensive seller....

I know they are sellers and not manufactors, but have no idea who is the manufacturer.
But warranty is given by a seller, not a manufactor, they sell it as there own but give no support what so ever on it.
If you have a problem they simply ignore it and hope you stop complaining and so there problem is gone.
Please make sure if you buy from China that you chose a seller which does give support!
The problem with my unit is it does not turn of anymore.
When plugged in it directly boot up, also when acc is off, when acc is turned on and off agin it should turn off by ACC control through can-bus control.
It seems can-bus is not working properly anymore....
When i asked support i get the most stupid answers such as:
check the 12V acc wire is connected... DUH there is no 12V acc wire in my car, it is fully can-bus, also there is NO 12v acc wire in the connector of the radio!
This then i get 4 times to check!
Now i get 5 weeks (i contact them 3 times a week) that there engineers are checking the software, FIVE WEEKS !!!!!
I am now aprox 9 weeks contacting them how to solve this (the unit was when i first reported it under warranty, now it is out of warranty...)
I never buy/order from them again!
I hope no one does!

I know a lot of sellers have bad support. I m just trying to see if I can help.
The stereo will have pins for ACC even if the loom does not have wires, what ahv eyout ried so far ? Have you asked on here for help ?
The MCU type will tell you who makes your unit.

Yes thx for any help, but the problem is within the canbus decoder i believe.
It is a unit specific for a Mini cooper, it has besides the radio/android part also the dials for fuel, obd and other car control lights etc, these also do not work properly anymore.
This car section is also controlled by the can-bus part of the unit.
The android part itself works fine, it is the can-bus part which is not working properly anymore.
The MCU have the letter KGL in it, i have really no idea who is the 'real' manufactor, but i actually doubt the manufactor will help.

Yes, I know the type, it has a round screen. KGL are the manufacturer - Shenzhen Kai Ge Le.
In factory settings, how many options are there for your car, for Minis ?
You can list CAN Bus decoder by manufacturer, how many many are showing for Mini ?
I ask this because you may be able to sort things out by getting a new CAN Bus decoder.

Seicane = Bad Customer Service + Do nothing for you after the sale.
I purchased a Head Unit from them back in June 2018. The bluetooth module has never worked and after going around with them about it, they sent me a different module, not the Parrot BT module I purchased originally. Replacement of the BT module requires disasembly of the unit, de-solder old BT, solder new one, but the reason the BT did not work was that a few of the SMD resistors were damaged during build or soldering the BT module in. 3 months since purchase and still dont have a working unit. Now they want me to ship the unit back but I know they will void warrentee due to customer opening the unit (not the factory), and will claim I damaged the board attempting replacement. Oh, did I tell you they never told me the BT module was soldered onto the main board?? When they offered to ship a replacement BT I was under the impression it was a snap in module simular to how PC processors or flat cable connectors lock in. They knew, but dont want to deal with problems.
Remeber, they are only resellers, not the manufacturer. They all buy from the same manufacter for the most part. Good luck if you do get one that works as expected from them.

If PayPal cant resolve this then I will be offering payment to anyone in the forum who can resolve the issues for me.. watch this space. Dont buy Seicane!

Hi typos1,
The spec for my unit as follows:-
Head Unit: Seicane s081988f
OS: Android 7.1.2 (Nougat)
CPU: Allwinner T8, 8-core Cortex-A7 @ 1.8GHz
Memory: 2GB DDR3 RAM, 16GB EMMC, 2xUSB2
Display: 9", 1024x600 capacitive
MCU Version: T8.3.19-23-10-E43101-171127
System Vers: V9.2.2_20171202.103838_TW2
Linux Kernel: 3.10.65 (20171129)
Security Patch Level: 2017-07-05, 7.1.2 (Nougat)
Issues still unresolved:
Microphone only works for phone calls, no android apps (no OK google)
Screen calibration slightly off by 0.5cm
Audio from AM / FM radio good, but Android apps (google maps, Spotify, youtube etc) audio louder from front left channel than all other channels
no root, unable to add some apps that I would like
Using AM / FM radio and waze, an alert in waze mutes AM / FM radio and it does not return. This doesn't happen in google Maps
When using google maps, something happens to the audio where it sounds like it changes the audio fade to front speakers more than rear speakers but when this happens the balance between left and right seems to be corrected resolving issue 3. System audio preferences for navigation set to use all 4 speakers but doesnt appear to be working
I suspect that there are other issues that I cant recall right now but whats listed above is enough to be unsatisfied with the product. The primary issues that I need resolved are the Microphone and the Audio being all over the place depending on what app is used. It just needs to be consistently balanced left to right, front to back right in the middle for all apps.
I am not against using an updated system ROM or MCU but I am not knowledgeable in this area and despite doing quite a bit of research I still havent figured out if there is a compatible release that I can apply to my unit, and frankly with all the time invested in research, forums, testing and trying to resolve issues with the re-seller I've got more important things to do with my time (work, family, hobbies)
Any assistance that can be provided would be greatly appreciated and rewarded.

You have an Allwinner chipset (not Rockchip or Intel Sofia) and "MTCD" or "MTCE" does not appear in your MCU field, so you dont have an MTCD/E unit and are in the wrong forum, try the Android Headunits general forum.

Thanks Migcep !! I think you saved me. So little about the same unit I bought for my Forester. Glad you shared your info.
This was a PM for @timduru but it wouldn't send.. So here it is for anyone and everyone that can help.
I'm thinking of replacing the nand on the tf700.. Can you help me source the right pin compatible chip? .. I don't have big plans for the tab, I only use it to read books and watch movies.. But the lag bugs me and I want to attempt the chip replacement job. I'm totally clueless as to the fastest chip that could be supported with the right pin configuration.
But I'm hopeful i could drop something beastly and perhaps give it a ram upgrade if the RAM is a separate and easily source-able chip.
I believe the fastboot mode along with the saved "wheeler" blobs will enable me write firmware and start the tablet with the blank new chip.
If I'm successful, i could do the same for other members who want to keep the development of the tab going(with them sharing the risk of failure/I'm not an idiot, but a botched solder job is possible) .. So that we can have one last stable ROM until the eventual death of the tab.
Thank you,
Please keep us updated on what you find out. I am still addicted to this tablet and use both the 700 and the 201 (for different functions of course!) I would also be curious about battery options out there..

If I'm successful, i could do the same for other members who want to keep the development of the tab going(with them sharing the risk of failure/I'm not an idiot, but a botched solder job is possible) .. So that we can have one last stable ROM until the eventual death of the tab.
Thank you,[/QUOTE]
Hi,
once I started going about it as well and found Elpida EDJ4216EFBG in our unit to seem very similar to the Samsung K4B2G1646C ddr3 chip.
Pinout seems very close except for T7 which is not connected in elpida but its an address pin A14 in samsung I do not know the implications had these chips to be interchanged. Also the ram in my unit is a hynix. Good Luck.

I'll look into the ram when I get the chance.. I was hoping that the pinouts are standard.. I don't think that data lines are redundant in general.. We'll have to ask around or try it for ourselves.
You don't happen to already know any super fast NAND chips with the same pinouts or even the mmc versions supported by the tegra?
Can you PM me the datasheets?
If you manage to pull this off, you will all be my heroes.

I'm a dentist.. I'm looking for someone to do the heavy technical work because searching for these things even with my knowledge is hard.. I'm sure there are ways for design that are learned in engineering school or on the job that I'm not ever going to learn...
The work with steady hands can be left to me.. I already have a few super hard reballing feats under my belt.
I'm really puzzled as how to approach this..
I will go through my library and find you the NAND datasheet as I've downloaded it years ago.
I guess i will start at digi-key and mouser and see what happens.
Wish me luck.

Basically if memory serves me right the samsung are the best bet.
I recently purchased an iMars branded low-end (1-16) Android 8 head unit from Banggood and of course, immediately pulled it apart and took photos and made notes of the ICs, layout, etc.
I was looking all over the board for the broadcast band radio chip and found all antenna lines led to the CPU (GPS, WiFi & FM).
When I looked-up the specs for the UIS8141e - SC7731 uP, I saw it's an all-in-one SOC that also has GSM baseband modems.
So - my question is this:
If this chip is capable of receiving FM broadcast via a DSP in the uP chip, and I have seen on some other (Banggood) HU specs that units with AM capability specify the same processor (might be false Chinese description though) , is there a driver, app or other software that can enable AM bad receive on the SC7731?
Unfortunately, the SC7731 datasheet is sketchy on RF capability details.
I have searched XDA and 4PDA forums for details and found none (except Russia doesn't use AM radio).
Any ideas?
Thanks

I have a UIS8141e-SC7731. Tapping System Info pops up radiotype:F Si47xx_f474x(0).
this family of chips provide FM/AM some do Shortwave also. The specs for the AM look good but the reception is poor on the head unit I have. I suspect poor input circuitry from the ANT.

Is your FM reception OK?
If not either you might need an antenna amplifyer.

NO it is a few db down from my OEM and another regular aftermarket radio.
I was thinking it may need to be amplified. The datasheets for the Si47xx eval boards show using amp for the AM circuit. The RF front end does suffer on this unit.
