Thank you for the advise. I agree, better buy an Android version.

Have my eyes now on the Lemfo LEM5. The pro is an upgrade of normal LEM5 versions. It has 2GB/16GB and Android 5.1. It lacks MicroSD slot and only 2G/3G (no 4G, Tele2 NL forces 4G use) but for my work sim (KPN) it should be fine.

Only time will tell if Android 6 it 7 comes available.

Price is $119.84 at AliExpress Lemfo store sale until 2017-09-21.

They also have a cheaper I4 Pro for $109.98 with the same specs but my feelings say I better go with Lemfo as better known brand.

What do you think?

Do you yourself have an Android 5.1 (or higher) that you develop for or can advise?

Edit; I see the MT6580 is not that fast. It can be compared with the old Snapdragon 410 (i.e. in Samsung S4) but also there the MT6580 lacks some functions already builtin the old S410. Believing the advertising the MT6580 could do everything you would want but now I re-considering if I want one...
[Other SmartWatches] Golem_:
I'm going to be honest with you, back in the day I loved the smartwatch concept, I don't like at all the direction the smartwatches are going too - I have stopped to be interested in this kind of items long time ago as long as I consider that android is the worst thing happened to our electronic devices

I took a look over some reviews - LEMFO LEM5 Pro is a quite good choice

any help?
[Other SmartWatches] Golem_:

as about your readback dump, send it to me
[Other SmartWatches] RANA_TOSH:
sir thats what i am telling that i am unable to make backup it always stops on 93% on the third offset 0x00400000 length other 2 just cant start any backup i guess it should have some different length?

can you please tell me how to properly dump?
[Other SmartWatches] Golem_:
the lenght is a quite standard thing. . . honestly I didn't hear yet about this kind of issue - my guess is that they put there an impossible code so that flash tool to get an error before to have the reading done. make a smaller length like 0x3b851e (about 93% of 4Mb) or bit smaller - enough to end the reading then send the bulk file to me
[Other SmartWatches] RANA_TOSH:

I made a backup of my ROM with FlashTool_v5.1516.00, use the Readback Extractor mtk 2.4 with the ROM file, I read almost all the threads of this post but I can not edit the FILE_01_MTK to change the faces of my watch, the original images do not appear, What is happening to me ?

No File_02_Mtk

Hello. Very newbie to smartwatches here.

I have a smartwatch that looks very similar to No1. G5.

Brand is MyWigo HR2 (MT2502 / Basic functions, no SIM, no SD, Heartrate)

I've managed to get a scatter file that loads Ok from No1. G5 firmware.

After readback I get a 4mb file.

When I process it with ReadBack Extractor 2.4 says file health is 100% and when I rebuild firmware I get 3 files and Binary Data Doesn't Match mtk6260a

INT_BOOTLOADER

EXT_BOOTLOADER

FILE_01_mtk (this file is only 33 kb)

Watch is hard to take apart to take a look at the PCB

The only thing I can read under the battery is the heartrate flex that says N03D-NB2-W05-V1.2

Any help will be much appreciated.
[Other SmartWatches] 98ali:
hello dudes, need help please.

looking for z50 mtk6260a firmware.

please help.
[Other SmartWatches] Golem_:
As I wrote in tutorial, before to start readback you have to check the length file from biggest to smaller, set first as length 0x01000000, if error the go back and set at 0x00800000 and only if this one either gets error you set it on 0x00400000

anyhow send me that readback file of 4MB
[Other SmartWatches] DSpawnZ:
Thanks for the reply. I forgot to mention that I've tried all sizes. Flash chip is 32Mb (W25Q32JV according to flashtool).

So the only option that worked was 0x004000000 the other options gave error.

Here's the dump

https://drive.google.com/open?id=0BwV1AgjR8k1oY2NLTGN0OG1BMlE

Thanks.
[Other SmartWatches] Golem_:
First of all I'm not sure how come you didn't get an error from readback extractor - I did get one <binary data doesn't match... etc - you can close the program>

Yes, the firmware contains a mismatch "error thing" - most probably they put it there in order to avoid rebuilding the firmware

I have attached your readback fixed dump - now you can extract it without probs
[Other SmartWatches] DSpawnZ:
Thanks for replying. i did get a Binary Data Doesn't Match mtk6260a.

Thank you for the modification. Will keep that modified dump and extractor resulting files.

You've been of great help. Good work.

Hi Golem, I'm new here and I mention I've done all your tutorials to make a Redback my IWO 4 mtk2502c who stayed in brick and asks me since you are an expert in this is that when you give the Redback Extractor I send me a legend that my binary file is invalid. You can guide me in this regard, thanks for the attention and response.
[Other SmartWatches] DSpawnZ:
First brick flashing my watch. Backup worked perfectly. You are a genius.
[Other SmartWatches] Golem_:
send me the readback dump you got
[Other SmartWatches] jhuertav2:
Thanks Golem but unfortunately I can not because XDA not let me for this reason. . .

"1. To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages. After approximately 10 posts, you will be able to post outside links. Thank you for understanding ! "

Well aside from this situation I want to tell you that I have two dumps, one with length 0x00800000 and another one in 0x00400000 since that was allowed by Redback, but at the moment of running both the Extractor sends me the message "Binary date is not compatible with mtk format ", who could be doing wrong?

And you'll wonder why doing a Redback to my watch, let me tell you that I bought it recently and it worked quite well, but when I passed some new "DIGITAL" faces through the Mediatek app when I activated them. . . I stayed in a brick, so I want to think that with your procedure I can rescue my original ROM and then restore it on the same clock. Greetings from Mexico City !

I have the MTK2502c watch and I bricked it trying to get other watch faces on it. Now it's stuck in a booting loop. I'm having troubles doing what you said. I've done everything you told me to do. Is there any way you could make a video version of this? Or maybe could I send you my watch so you could fix it? That sounds pretty lazy but I can't figure out what I'm doing wrong. I can assure you I'm doing everything you told me to do. I've gotten closer to fixing my watch with your advice then anything I've seen out there. I'm just very frustrated because no matter how hard I try it still doesn't seem to work
[Other SmartWatches] Golem_:
If stuck in bootloop. . . better wait until it drains up the battery then connect to flash tool - press format / check <reset to factory default> / press OK

Hello!

I have a GT08 with 6261d chipset. I wanted to make a readback and followed your instructions carefully, but the readback was aborted at about 89% with an error message and now the watch is not recognized by my PC or by the flashtool anymore so I can't retry readback or flash new firmware. When I connect it to my PC I hear the connection-sound but nothing happens. I re-installed the mtk drivers, restarted the pc and the watch but nothing helped so far. Is there anything left I can do? Please help!
[Other SmartWatches] Golem_:
I didn't hear yet about this kind of issue - the only thing is coming in my mind is a hardware thing like low quality cable, computer's usb unit or something like this - try to reinstall motherboard original drivers and replace the cable
[Other SmartWatches] the steve:
In the meantime I uninstalled the smartwatch completely from windows device manager and after reboot I installed all the drivers manually again. The watch is still not recognized in the explorer but it is recognized by the flashtool now. At first I made a readback (successfully this time) and I will search for a working rom from the large collection that will maybe solve the windows problem.
[Other SmartWatches] the steve:
New problem...

I wanted to flash the rom I created from my successfull readback to the watch. In the flashing process I get an error message which tells me to 'ask for help' so I hope anybody can help me. I did not find another working rom yet, mostly the touchscreen doesn't work and the colours are inverted. So it would be very important to get my own rom running again!
[Other SmartWatches] Golem_:
send me the readback dump you got with flash tool
[Other SmartWatches] the steve:
I hope it can be repaired somehow. According to the seller the manufacturer is Gstek, I don't know if this helps somehow.

Thanks in advance for taking a look!
[Other SmartWatches] Golem_:
our chinese fellows just wrote to the flash a new firmware without to remove the existing one - that's why the readback extractor gets two overlapping files instead of one - did a small correction in the readback dump code and now it has to work
[Other SmartWatches] the steve:
Thank you for the time and work you put in this! I'm afraid the touchscreen still doesn't work :(

Edit: After flashing it twice and taking out the battery again before reboot it works again!!!

Thank you so much, you saved my watch!

I won't go into deepe explanations, but I'll just be brief;

After the code was done, the important thing bout these watches shipped from Wish stores was:

MTK61D_BTDIALER_11C from 2017

I'm pretty familiar to Smartphone flashing, (Xperia x8, Xperia Z-first ed, Samsung Galaxy sII)

DZ09 mtk 6261DA

Hello, I'm a newcomer here and you're wasting my bad English, I'm using Google. I bought a DZ09 watch and I'm trying to make a FW backup.

I've read a lot of topics, especially Master Golem, but I can not get in touch with my watch.

I have installed mtk drivers v1.1032.1 which apparently works and when trying to test RAM my Flashtool throws a bug (5068)

and Flashtool Read Back throws me a bug (5095).

I use Flashtool 5.15.16.

I tried different scatters by Golem but it did not help.

here are the readings read from the watch display:

Heureka, finally did it and I have a backup of orig.FW.

The error was probably in connection with the driver. I opened the device manager in the W7, showing unconnected devices, and finally, after several attempts, I managed to connect my watch.

Thank you Goleme for the advice and description of backing orig.FW

Smartwatch v8 trying to get firmware

Hi Golem and first of all many thanks for all the efforts put in your work and in this forum.

I have the Smartwatch v8 which I think is a clone of some other gear and I´d like to change the watchface. Unfortunately, even after following all the steps described in 1st page in order to make a copy of the original firmware, I got stuck at ´´your binary is not compatible with mtk format´´ after loading readback file. So now images appear upside down, only on half of the screen and doubled with no access to the menu. Can I fix something at this point?

[Other SmartWatches] Golem_:
theoretically, as scatter, can be used any 32M firmware (check the collection of firmwares)
[Other SmartWatches] megaminxwin:
That seemed to work when I did it, but after flashing other firmware - which failed, the touch screen wouldn't work - I can't restore from the backup:

[MAUI/MOLY] the addresses of some Load Regions in this scatter file are overlapped! Please ask for help.

Sooo I'm taking that advice; even after using your tool for reassembling the firmware and confirming it worked, it still isn't.

Hi all,

does anyone here have a fw for a myria urban my9500 watch? I bricked mine
[Other SmartWatches] Tommmii:
Thanks for your time & effort in this thread !

i've got a few questions, before i proceed to brick my watch :

*is a scatter file required for doing a readback ?

*for readback, wouldn't it be possible to create 3 universal scatter files? 128M & 64M & &32M.

*how to know what size of firmware is required ? for instance , is a MT2502C always 32M and a MT2502A always 64M ? How to know?

*your links to the firmwares ( google drive URL ) only specify 64M or 128M, where are the 32M files ?
[Other SmartWatches] Golem_:
1. yes, it is a must - actually we are not speaking about a scatter file, the whole firmware it is a scatter for your readback

2. configuration contained inside the firmwares are different so... no, we cannot create universal scatters

3. if 6260 size can be 256 or 128, if 6261 then size can be 64 (rare case) and mostly 32, when 2502A then 128, when 2502C then 64

4. they are spread throughout the folders - summing the main files in the firmware kit is coming smaller size than 4 MB

Hello Golem,

I tried to flash some other ROM's on my smartwatch X86 (MT6572) but bricked the watch :(.

DZ09 Clone mt6260da firmware readback extractor Help

hi. I backed up 4mb firmware from DZ09 mt6260da but every version of readback extractor keeps failing (binary data is not compatible with mtk). Thanks in advance for any help. Zipped rom file below. Thanks
[Other SmartWatches] Golem_:
as the title says, this thread is about mtk feature smartwatches, your watch is a OS android watch
[Other SmartWatches] Golem_:
I'm really sorry my friend, when you did the readback your flash memory was already wiped out, most probably you did before a memory test and forgot to uncheck NOR flash test box - so your backup now is simply a void
[Other SmartWatches] ildar_prophet:
Looking into the 2502 documentation it seems that the ReadBack does read the "Boot ROM" (usually 4MB) while it also has external "Serial Flash" containing the FAT partition.

It is possible to read and kinda "FTP in/out" files with MAUI Meta tool (thanks, [MENTION=7026470]Golem_[/MENTION] !). But I found no way to get the full partition image. Hints/ideas?

Hi I own a dirt cheap A1 watch and dumped the firmware GPLUS61A_11C_NX9_PCB01_gprs_MT6261_S00.TA03S_61D_W88_B_RQ_TN_V1_20170825 (32Mb NOR)

I really like the watch, except for the one flaw it has, it stores only one notification :(

Even if multiple notifications were received, the notification viewer with the "satellite ground station" icon, only shows the most recent notification though it shows "1/1" at the top, which suggests it can store more than message where you can scroll through.

Do all firmwares have this one message limitation?

And can anyone see what touchscreen my watch has? I tried a couple of other firmwares but so far touch didn't work.

Final question: is it possible to combine firmware parts from different firmwares? I am referring to the two parts FILE_01_mtk and FILE_02_mtk

I can imagine the drivers are in the first and the apps in the other.

Thanks for any help!
