Z30 xcsource development?

Hi everyone, I just got a Z30 link and I would like to start messing with it.
Firstly put some nice watchfaces lets say.
But there is nowhere to find anyone with information about it.
I tried some software you suggest here, Maui META recognizes it, but cannot take backup and flash tool needs extra settings file??
Sorry for my ignorance, but I have never before used a smartwatch so it's pitch black for me
Thanks!!

I guess nobody tried this watch yet.
If I find anything I'll tell you

I received this watch as well. The OS seems very limited, as compared to reviews I see for the eg DZ09. The notifications don't pull down, the icons can't be arranged, and if you try to reply to an SMS from the notification the keyboard does not appear. I've successfully performed a readback and created a backup using the readback extractor by Golem_ but I can't get any other firmware to work (boot sound but then nothing on the screen)
I would love to be able to load a different rom to get the full functioning OS, it seems odd to be stripped down like it is considering it appears to have the full 128Mb NOR Flash and the newer MTK6260A CPU.

did you try to change any of the watchfaces?

Yes I tried but none of the watchfaces were in the resource dump of the ROM.

Lemfo K1

Hello,
I bought the above smartwatch afew months ago.
Last week accidentally I changed the watch's resolution to HD and now the digitizer doesn't work and I cannot change it back to normal resolution.
Does anyone know how to do a hard reset on the watch?
Does anyone know a software that i can use in order to reset the smartwatch from my pc?
Thank you
George
P.S."I tried to contact lemfo, but they didn't reply on my e-mail"

Hello.
I have Lemfo K1 as well. Try to flash firmware from Q1 (look like same watch). Now I have a "brick".Watch doesn't switched ON.
Please anyone can upload original firmware for K1 or help me how to back up my watch back!

Hello Barmenchik, i tried to make a backup of the stock rom of my Lemfo K1, but i don't know if it's usable.
I will upload it once i have time (maybe this evening).
As far as i know the Lemfo K1 Firmware is more like a KingWear KW88 like a Finow Q1.

you'll have to flash the rom again if you can't access the settings.

OMG. No. It was tick.. Thats mean my watch go to the bin?

SP Flash Tools show me ERROR S_FT_ENABLE_DRAM_FAIL (4032)

It took a little time, but here is my Backup of the Lemfo K1 Stock ROM V06: https://drive.google.com/drive/folders/0B3m8CCL9zH-EOUFhM2c1ZTl2Y1k?usp=sharing
It's not complete - the userdata Image is about 6 GB (i think mostly empty). If you need it, i can also provide it. And there's no nvram image inside the zip (i don't want to share my IMEI).
But as I said: I don't know, if the Backup is usable. I took the scatter file from a No.1 D6 and compared the adresses and sizes with my /proc/partinfo. Only userdata had different adress and size.
Hope it helps.

Scatter file is from No.1 D6, but I modified the userdata address and size according to my /proc/partinfo. The other addresses and sizes are the same as in my /proc/partinfo so I leave them untouched. Then I used "Readback" to create the Image files.
On the "Download" Tab you have to select the file in every line with a click in the field "Location". Then you are able to tick the checkboxes.
The preloader file seems suspect. Perhaps it's not enough to save the partition as image. I try to get more infos about extracting a loader.bin.

ok. sorted.
now Flash Tools FC when I try to connect watch.:crying:

My first USB Cable was weak. Try to change it and try another USB Port.
What OS are you using? The ZIP file in my Google Drive contains CDC drivers for Win7/8/10 - signed, as far as i remember.

Worst case I would disassemble the back cover and disconnect the battery to reset the Watch. You can also check the pins under the back cover if they have proper contact.

Custom Faces for SMA-R?

I purchased a SMA-R smartwatch. The official app for this watch is the Fundo Wear app. When I load VXP files into the appmanager folder the VXPs do not show up in the app. I have installed the Mediatek smartdevice app. The VXP files show up, I can install them on the watch, even get an install message on the watch, but the installed faces do not show up.
Anyone know how to load custom faces on this watch?
My appologies if this has been covered before. SMA-R search comes up with every mention of "smartwatch".

Hi,
I have sma watch too, it was working at this form:
Connetct the watch with the cable to the computer, open at mass storage mode. On the computer copy the folders to the watch, maximum 3 at one time, no more!
After this, on the watch at file manager go to the folder you want's to install, open vxp file and look, it is works on the watch.
Very important, no more than 3 install same time!
Before you uninstall watchface from watch, make your watchface for original watchface what was come with the watch! If not, your watch will be bricked as mine.
Please make a save from your firmware because my is bricked and I search for firmware.
Here is the step by step guide to make it.
Please post the firmware here in xda.

Microwear H7 smartwatch (MTK6737, 1+8 Gb)

I`m ruined original firmware without backup. Can`t find firmware on the web. Microwear H5 firmwares are (almost) compatible except weird and unreadeble screen. Requesting backup or firmware.

Stevea 76 says that all i need is original boot.img.

If you go to the official website for the Microwear smartwatch at microweartech they have a Support icon on the homepage then a Firmware option in a list. On that page is an email address to request the needed firmware file for flashing the Microwear H7 with a PC.
Update: I'm Sorry but I wrote this before trying the email address. The support and marketing email addresses shown on the website are down. There is a tab on the site that says messages where I sent a note and am waiting for a reply. There are a few addresses and numbers throughout the site that I will try too. If I can get the firmware I'll upload it. They are very clear about the firmware file existing and being available upon request so it must be obtainable.

Am i the only one user of this watch?

Yes, i`m kind of idiot, so i bought second watch, and i made backup of them. So i debricked first one. If anyone interested in my backup, please inform me.

You should post it online to help out other people.

1. I made full backup via flashtool - this means it will clone my IMEI on next flashing watch.
2. I don`t know how to make a "ROM" from backup.
3. Backup weights more than 5 GB, and it`s kindly costly in my country, because i have only 10 GB of traffic per month.
So, can anyone teach me how to make a ROM from backup?

I tried out ROM_BACKUP-SPLITTER application and it did some work, but there is no preloader file.
Flashtool backup size is 7,5 GB, i`m ready to save it on googledrive, but inside still my personal data.
Please, give me a link for splitting manual.

I remove the connectors from antenna cables,because chinese swap the antennas in strap,
The WIFI work for max. 3m and BT for 30cm. GPS not work. I removed the strap and plug it vice versa everithing worked fine,but i cannot connect the connectors. I need longer cable. I don't know how can i solve this problem at this moment,but i'm thinking.

Nice DIY pic's! kudos

I found a solution for call sound not routed to bluetooth headset. Install this,and everything work fine. dialer Make call this dialer and you can hear the voice in headset. You need some configuration for good look.

Wanted Firmware for Chinese 7" Head Unit with AC8227 YT9216B_00002_V004_20190530

Hello I need help, by mistake I flashed SP_Flash_Tool a version that in the end was incompatible with my AC8227 YT9216B with what remained brick.
I am trying to recover it with versions that download YT9217 and YT9218 but it is known that they are very different from the version that I had the YT9216B_00002_v004_20190530 and by means of USB bridging the test point close to negative but even though the program SP_Flash_Tool- 5.1916 always ends with failure 4032 or 5054 both related to the DMRAM.
There would be someone in the forum that could help me indicating where to find the link to download my ROM? I have already reviewed the month of 400 pages of the 4PDA forum and I did not find it.

I believe this (Link) is the version you are looking for. Its a memory dump. If you need help flashing it, follow the instruction here. Error 4032 means you are not using correct scatter file. and 5054 means there is not correct preloader file to go with the scatter. You can try the one I have shared, or copy the 2 files from other similar firmwares offered at 4pda
I hope it helps.

Thank you very much for your help, I will try it immediately to see if with a little luck and your copy of the firmware convinces my computer and starts once and for all, although I do not have too much hope, but anyway, we will try achieve.:good
Nothing, still the same, error 4032 put it as you put it.
Connected to a 12V source the screen starts in a blue color and there is no change unless the reset button is pressed, I don't know if that can indicate any other fault such as that the MCU memory had been erased or corrupted and that is why he does not stop doing anything but the question is that following the procedure for the use of the "test point" step by step always cindependently of using a flash tool or another, of using different scatter files or firm YT9216 / 17/18, B, Whatever the question is, always, always the blissful error 4032 above all.
I don't know what to do, any suggestion is accepted even if it is to use a hammer as a tool.

did you try the scatter and preloader from my post?

yes both and in different ports of the PC (windows10)

the error you have described is only the wrong scatter and preloader file. its only a matter of finding the correct one. I also found the scatter that worked from a different firmware(the firmware didnt work but only the scatter did) , and installed different firmware. It might be possible for you to extract original scatter from the device using MTK droid tools.

Thanks, I found about 20 scatter files between AC8227_Android_scatter and MT3367_Android_scatter, I have about 10 preloader_8227l_demo_ (Preloader) and another 15 different SP_Flash_Too.
I will have to arm myself with patience and try different combinations (so far I have tried more than 50 with the same result, the always present ERROR (4032).
We'll see if I get it or give up before, the ideal is that somewhere the files were found together and that they were already successfully tested but that would be daydreaming.:crying:
Another possible solution would be to enter the way that I would recognize a USB Flash drive with an XYAUTOUPG file or whatever I had tried with it but since this brick after pressing the reset it still does not know.

wow, I'm impressed by your patience
I also downloaded many files from the Russian forum. One of the problems I faced is if the folder name contains some Russian characters, the flashtool gives similar errors. Also some suggested, removing first 4 lines from the scatter file helps in some cases.
I remember I also had disappointments first. Many times I packed everything up and put in storage, but then brought it back for further testing. and one day I got lucky. Hopefully you too will fix it soon.

Thanks for your help but I don't get results on the other hand, the test point disappeared from using it so much, it was deleted and since the processor does not have the pins in the air it can no longer even be tried.
I do not know if there is another test point or one that could help for the purpose that is sought and is: to start this brick.
On the main board, from where there would be a SIM socket, there is a connector that could appear to be a USB socket to be used by the Technical Service in the commissioning of the newly assembled ones.
Anyway, I just want to be able to recover my radio.
Thanks for your help.

Hi there I exausted the whole xda and russian forum for something that can work..

yesterday it still connected to my laptop....you could hear it connect in windows but i couldnt get anything to load on it... all sorts of errors in Flash tool....
eventually i I Did manage to download the preloader onto ny headunit from firmware I found in this post....
I found out that I had to use this order: I would connect my usb... click download in Flashtool then it starts... and I switch on the power of my head unit.... and it completed the upload of the preloader..... So i finally thought Yessssss now install the rest of the firmware.... but after this I had no connection with my head unit... it doesnt find it anymore trough USB.....
but after that I installed that preloader file... I can no longer get any connection no more to my hu....
please help me out.... I also did read some stuff that you need to connect or push 3 spots togheter on youre pcb...?? does anyone got more information or a clear foto of wich and how I connect these 3 spots?

I have this radio version and I can't update it. I tried USB update with a flash pen USB and gave me an error. I tried with SP flash and gave me error 4032 with the test points method... I don't know what can I do more.

I gave up on this junk radio a while ago...worked for a few days then it just went blank and got really hot so i pulled it out. Now it sits in a box in pieces.

My radio looks like a PODOFO, It's a YT9216B_00002_v004_20190826 firmware but aida64 show yt9218B.
I tried some methods, nothing worked. I tried to update via Android update, flash with USB with SP flash, flash with USB pen and sd card, without success .I decided to try again. Can someone help me, and on first place tell me what is the correct firmware for this device? And a full tutorial step by step (without shortcuts)? or some tip that can help me?

yt9216b

Hi there I exausted the whole xda and russian forum for something that can work..
exausted different forums.... and tryd a lot of firmware and methods...
I did about the same I am afraid.... no backup and now black screen on startup and no connection to usb no more......
yesterday it still connected to my laptop....you could hear it connect in windows but i couldnt get anything to load on it... all sorts of errors in Flash tool....
eventually i I Did manage to download the preloader onto ny headunit from firmware I found in this post....
I found out that I had to use this order: I would connect my usb... click download in Flashtool then it starts... and I switch on the power of my head unit.... and it completed the upload of the preloader..... So i finally thought Yessssss now install the rest of the firmware.... but after this I had no connection with my head unit... it doesnt find it anymore trough USB.....
but after that I installed that preloader file... I can no longer get any connection no more to my hu....
please help me out.... I also did read some stuff that you need to connect or push 3 spots togheter on youre pcb...?? does anyone got more information or a clear foto of wich and how I connect these 3 spots?
Or maybe now a way I can unbrick my device or have correct software for me??
