Help! Not able to complete 2.3.6 - first timer

Hi, first timer here trying to flash my stock Chinese Amazfit to International/US to get English language.

I’ve read as much and watch YouTube here and there.

Then proceeded with my laptop using windows.

Installed ADB and Fastboot.

Both confirmed with showing device list.

Proceed to get unlock code and confirmed status as Unlocked: yes.

Next, downloaded 2.3.6 International/US firmware with OTA. Link from the first post here.

Run flash_US.bat -> it stopped at

5. Checking adb connection in recovery mode

Attempt No.:1/5

No connection detected. Retrying...

(This goes on to Attempt No.:5/5)

Too much attempts with no adb connection

Aborted installation

Press any key to continue

Run US2.bat -> unsuccessful too. it shows running through the whole thing and it just ends without anything installed. saying 'no devices/emulators found'

Am I missing something?

Phone is on Chinese A1609 2.0.13.0

Please help...

Thanks in advance.
[Amazfit] Saratoga79:
Can you post all the installer output?

There is no adb connection with the watch when the modded recovery is booted. Retry after restarting your PC in another USB port or go for the manual method, maybe your watch needs more time to get adb connection on recovery mode.
[Amazfit] lkokming:
I was trying to figure out how to post the screenshot here.

I’ve tried reboot my laptop and also tried on different USB port. Same result.

Just to confirm, the watch should be just left turn on in idle state, right?

Just launch the .bat file found in unzip folder, right?

Looks like I’ll try the manual way as shown in your original post.

Also will try to upload the installer output screenshot somewhere later.

Thanks.
[Amazfit] Pallaros:
Hi !

After official update of 2.3.6.0, I have several bugs. I need to go back to 2.3.5.0. I wonder, if with the use of your tool I can downgrade to 2.3.5.0. Is it safe, or I can't do it? Thank you for your answer !
[Amazfit] Saratoga79:
Which bugs? If you can elaborate...

You can switch to any firmware you want.
[Amazfit] Pallaros:
Thank you for your rapid answer. The major bug is that the watch turns on backlight by itself (like the 'Raise hand to activate' option, but with this option set to 'off') when walking or doing any activity. This is a serious battery killer. I tried factory reset, switching off backlight, setting auto backlight to a specific midnight time range nothing worked. When starting to walk or to do something with my hand, the backlight is on. The strange here is that when I am raising my hand, it doesn't. So, I believe that this has nothing to do with the 'Raise hand to activate' option. But it's very annoying, I have 44% battery in 2 days !! That's why I want to downgrade.
[Amazfit] awtms:
I want too to downgrade.For me the main bug is the error on sync with my phone!!
[Amazfit] Pallaros:
Problem during flashing...

https://imgur.com/a/yjfhzDr

Any ideas?

Thanks !

EDIT: No need... Figured out.. Must unlock my bootloader first. Sorry for bothering...
[Amazfit] lkokming:
Hehe.

That’s the exact same image I wanted to post in regards to my issue too.

OP suggested to try manual way.

I haven’t try it though.

Are you coming from Chinese A1609 too?

---------- Post added at 02:09 PM ---------- Previous post was at 02:06 PM ----------

Hi Pallaros,

I checked that my Unlocked: yes.

But I’m having this error still.

Did you leave your watch power on and idle when started the .bat installation?

Thanks.
[Amazfit] Pallaros:
Hi!

After I unlocked my bootloader I have successfully downgraded with the automatic tool, having my watch in idle (watching watchface).

I have the English watch, never was Chinese.

The only problem I now have is that I didn't know that the bootloader cannot be relocked.

If I knew it I wouldn't do the downgrade yet... Anyway...
[Amazfit] lkokming:
Now it makes me wonder if my interpretation of bootloader Unlocked is the same as I follow the steps to Unlocked it.

Is this the step whereby we send the watch info via the form in the link provided and then using the code that is emailed to us? Then we could set the mode of Unlocked: yes. Correct?

Right after this step, i reboot the watch normally (press and hold power button).

Once the watch is up running normally, i just run .bat file, correct?
[Amazfit] Pallaros:
No. I have run this tool : https://xdaforums.com/smartwatch/amazfit/tool-huami-amazfit-tool-unlockadvanced-t3739828

And I unlocked bootloader from this. (It has a button Unlock bootloader).
[Amazfit] chrisuwd:
Thanks - very cool!

I have a question - will there be the German language?
[Amazfit] lkokming:
I've downloaded and ran the tool.

Upon pressing Check Bootloader Status, a popup box appears and says: Your Bootloader is Unlocked!!!

Pressing Unlock Bootloader brings me to the page to extract watch info and link to getting unlock code (which I have done manually).

So, running US.bat again. I'm still stuck at the same step 5.

The watch shows the triangle sign with an exclamation mark on it.

Program ran through the same retrying 5 times and aborted.

Please help...

The screen is the same as Pallaros posted earlier.

I haven't try the manual step by step though.

Apart from this Windows laptop, I have a iMac at home. Does this run on macOS? But how to I get adb and fastboot drivers into Mac?
[Amazfit] Saratoga79:
What is the output of the installer for step 3.?
[Amazfit] lkokming:
here's the output screen shot (US.bat and US2.bat):

I'm stuck! :crying:
[Amazfit] Saratoga79:
Retry without running the installer as Administrator. If it doesn't work go for manual installation method.

Btw, what is your current Rom version?
[Amazfit] lkokming:
Tried terminal on windows.

Still stuck...

ROM version is 2.0.13.0

---------- Post added at 02:50 AM ---------- Previous post was at 02:42 AM ----------

another attempt with manual installation.

same end result with slightly different error message on boot recovery step

what can I try next?
[Amazfit] Saratoga79:
When you "flash" the modded recovery on Step 4

fastboot boot recovery-mod.img

Ensure you see the triangle icon on watch and wait around 30s and then check adb connection

adb devices

You should get something like

List of devices attached
9dee1d33 device

If you don't get device info, check again adb connection every 10s, you should get adb connection soon or later (1min max time).

Once you have adb connection in recovery mode, you can continue to copy files to the watch.

If still you don't get adb connection, download this old modded recovery, unzip the file, copy and replace the file to installer's folder and try again.

Got an No command screen after failed updated

Hi Friend,

Could you please help me? Since I ve tried to update my Stratos to 2.3.7.0 but It failed at first time, maybe I unplugged it too early cuz I saw the no command screen.

So I tried to find the way to fix it in this forum but It doesn't work.

The error still the same I still face the No Command Issue but my pc shows error say that "Error: more than one device emulator"

Could you please help to suggest?

Thank you
[Amazfit] Saratoga79:
Maybe you have some other device or emulator installed or plugged if you get that error.

The no command screen is the fastboot mode where the modded recovery is booted in order to flash the firmware, if you get waiting for device string on the installer and nothing else you need to fix your fastboot drivers, but first fix the previous error.
[Amazfit] Sungil Shin:
First of all, I appreciate fot your support.

I proceeded 2.3.7.0 firmware installation with your manual.

I could succeed until No.5 steps.

My watch show me the triangle with an exclamation mark.

But Next step didn't have any answer.

I could know that adb port didn't appear after

the triangle with an exclamation mark.

Let me know what the solution is.

I'm waiting your reply.

thanks.
[Amazfit] Saratoga79:
Post here a picture of the installation process to see what the problem is. You can also try the manual method.
[Amazfit] cumbrianrunner:
Could this be used to roll back to 2.3.5.0 assuming I unlocked my bootloader from 2.3.7.0?
[Amazfit] Saratoga79:
Yes, sure.
[Amazfit] cumbrianrunner:
Thank you - I assume the instructions in the first post contain a typo?

'Property installed ADB and Fatboot drivers as system wide'

I assume this is supposed to be Fastboot not Fatboot?
[Amazfit] Saratoga79:
If you don't have Fatboot driver installed, you can use Fastboot driver instead :p:p:p
[Amazfit] Gunterius:
Hello,

Thanks a lot. I managed after few hours try and search.

Friendly suggestion :

Could you add in the requirements section a link to the thread with the unlock tool ? It took me long to find that + the drivers so i was always stuck before.

2nd q: now i have the last US english one, I noticed several apps i got before are gone, like Alipay etc. is there a way that i add these manually somehow ?

Thanks again for this thread and help !!
[Amazfit] willym.hu:
Thanks for all the work!

Unfortunately I experienced the following problems when I wanted to return to firmware version 2.3.6.1 from 2.3.7.0 :

1. Flash_US.bat didn't work, so

2. I ran Flash_US2.bat instead, and

3. at the 'Flash temporal root' step the process stopped.

The problem should be the following: the watch didn't reboot into fastboot after the command.

When I tried to do the manual and wrote the 'adb shell reboot bootloader' command I got the following answer:

- exec '/system/bin/sh' failed? No such file or directory (2) -

using port=5555

My watch shows the Amazfit logo and does nothing.

Even I can't start the manual installation because of the problem.

Is there any solution or I should consider my watch as a bricked device ( :( ) ?

Any help is welcomed and appreciated.

Another info: 'adb reboot' works, also 'adb devices' command shows the watch. 'Fastboot devices' command doesn't show the watch (certainly).
[Amazfit] Saratoga79:
AFAIK there is no 2.3.6.1 version for amazfit verge so I don't know what are you talking about.

Are you installing this on Amazfit Verge or on Amazfit Pace?

If so, you have done a big mistake.
[Amazfit] willym.hu:
I tried to install it on Amazfit Stratos (A1619).

The bootloader was unlocked before I started the process.
[Amazfit] Saratoga79:
Yes my bad, I thought this was Verge's firmware thread :silly: Too much version numbers in mind.

Check the manual installation method post (Post #2) about "How to Unbrick your watch".
[Amazfit] willym.hu:
OK, I'll try it. I hope it will help.

Thanks for the advice.
[Amazfit] willym.hu:
Your advice worked! First it took me several tries to start fastboot mode, but after that I could install the ROM manually.

Thank you for advice again.

Now my watch has ROM version 2.3.5.0 on it. :o
[Amazfit] Saratoga79:
No, this is the Original/Stock Firmware installer.
[Amazfit] saarakura:

I received an AmazFit Stratos as a present. It was of course, in Chinese. This tutorial helped me install the stock international firmware. Again, thanks!
[Amazfit] andreandrade1:
guys i need some help here

kinda noob doing this so sorry about noob questions

got my stratos 2 weeks ago and today I had the brilliant idea to change the watch face of him, installed an apk and that locked everything, I could not use the watch and I lost the connection with my cell phone. I'm trying to reset the watch but I'm having difficulty. I can get into fast boot mode without problems, but when I start the process of reseting, this appears. if you can help me or even show me another way, ill thank you alot.

Thank you
[Amazfit] Saratoga79:
You have to unlock the bootloader, and don't run the batch file as Administrator just in case.

[Amazfit] Monotoko:
Anyone know how to get this thing into fastboot/recovery? I followed the instructions perfectly with an unlocked bootloder... ran flash_us.bat and let it go through the steps (https://imgur.com/hwRmPQN) but it seems to be in a bootloop... launcher keeps crashing.

I have A1609

It's got the same watchface I put on before I flashed... should a factory reset have been done first? Shouldn't the script have done that? I'm confused...
[Amazfit] Saratoga79:
Everytime you flash a new firmware or ROM, do always a factory reset.
[Amazfit] Monotoko:
Got it, I managed to get TWRP onto the watch and factory reset that way, all good now :good:

its almost 20 minutes, and no change

Same here. Retry on another USB port or/and use the newer modded recovery file. It takes no more than 15s.

[Amazfit] jerry_inc:
Thanks, I tried the manual process, and successfully installed the international version.

but I have a different problem now.

I bought this watch today, since it was in Chinese so i couldn't test it (because my Chinese is very bad). so I decided to unlock its bootloader and install international firmware. and now i came to know that its is not able to detect my heart rate. i guess fault heart rate sensor.

so is there a way to undo every thing and lock the bootloader again? so that I can send this watch for replacement?
[Amazfit] Saratoga79:
I can't download the zip file, you can upload it here as an attached file, but when you use fastboot boot recovery, it should boot/start the recovery with adb support.
[Amazfit] Guto ViP:
[MENTION=5062938]Saratoga79[/MENTION], this FW works with Stratos 2S (sapphire version)?
[Amazfit] Rusikxxx:
In the batch file, I just removed the download of the modified recovery and boot, whom I tried many different. Below is the one that works for me.

As I understood from the script, it should wait for the download of the recovery, but this does not happen and the connection with the clock is lost. I did it manually via TOOL_ALL_IN_ONE as seen in the screenshots. The problem as I understood from many and is related to recovery.
[Amazfit] Saratoga79:
I don't know, if they have same hardware it may work too.

I see, you are flashing the TWRP instead of booting it, that's why you need to "start" the recovery, when you boot, there is no need to "start" anything as the boot command (should) does it already.
[Amazfit] 1immortal:
should work, both watches has the same hardware
[Amazfit] Guto ViP:
I have this doubt because even the two having the same hardware, the Amazfit app recognizes mine as being Stratos + (2S)

Why

---------- Post added at 11:12 AM ---------- Previous post was at 10:51 AM ----------

Hello, an issue appears after going back to US stock from "PACEficator Project|Everest 2.0.55.1 ROM v1.8 Installer|Amazfit Stratos (2019/03/14)"

Watch is A1619S - Stratos + (Bluetooth device name Amazfit Watch-C9E9) - all before flashing the 2.0.55.1 ROM v1.8 Installer

Watch was flashed to 2.0.55.1 ROM and then back to Stock US (Stratos_Stock_US_Firmware_2.3.6.1)

After flashing rom:

- watch name changes to Amazfit Stratos and before was Amazfit Stratos 2S,

- Amazfit app shows Amazfit Stratos before was Amazfit Stratos +

- Bluetooth device watch name persist as Amazfit Watch-737D before was Amazfit Watch-C9E9

any ideas what should be done to fully return to US Amazfit Stratos +
[Amazfit] Saratoga79:
I didn't know about a A1619S model. How did you install the ROM? With manual method?

Back to this topic, well this is normal, as you are flashing the Firmware of A1619 device and not A1619S device firmware.

Anyways, I don't think you will face any trouble, just different watch name. Check the SN matches the one printed on the back of the watch.
[Amazfit] Andy_Stratos:
It went smoothly and ROM installed correctly.

I can confirm now that only CN firmware names correctly A1619S as Amazfit Stratos + and its visible on Amazfit app.
[Amazfit] Andy_Stratos:
In my case Watch A1619S brand new with ORG US stock FW before flashing was recognized by Amazfit app as only “Amazfit Stratos” and info on the watch display was as well Amazfit Stratos”

Flashing watch with CN FW Project|Everest 2.0.55.1 ROM v1.8 Installer made the watch discoverable as “Amazfit Stratos +” by Amazfit app and info on the watch display was changed to “Amazfit Sports Watch 2S”

I already made flashing (Everest 2.0.55.1 ROM v1.8 Installer) of two units Stratos+ (A1619S) and those guys works great thanks to Saratoga79.
[Amazfit] Andy_Stratos:
Here are some pictures before and after flashing:
[Amazfit] RR_TW:
Hi,

Thanks for your post, gives me some hint for unbrick my watch, I'll try to flash it with US rom later.

I bought my Stratos directly from taobao, so it's CN version. If I would like to flash it to original status, did you know where can I download CN version rom ?
[Amazfit] lfom:
bbs.huami.com
[Amazfit] RR_TW:
I download CN rom from there before, but it's several files & folders, not like a system.img.gz.

Tried following command but it didn't update :

adb push update.zip /sdcard
adb reboot update

It just reboot and shows the "A" logo (and with a red dot), nothing more.
[Amazfit] lfom:
They are meant to be stock recoveries/updates for CN watches so unless you already have a CN firmware then probably it won't work. If you want to flash it over INTL firmware I suggest that you use AmazeROM instead, up to 2.6.4.1, then update to latest version either manually or using OTAs.
[Amazfit] RR_TW:
I had download US 2.3.9.0 rom, and run the following command passed with no error message :

fastboot.exe devices

fastboot.exe boot recovery-mod.img

adb.exe push boot.img /data/media/0/
adb.exe push system.img.gz /data/media/0/
adb.exe push md5s.txt /data/media/0/
adb.exe push flash_rom.sh /data/media/0/

adb.exe shell sh /data/media/0/flash_rom.sh

adb.exe shell rm /data/media/0/boot.img
adb.exe shell rm /data/media/0/system.img.gz
adb.exe shell rm /data/media/0/md5s.txt
adb.exe shell rm /data/media/0/flash_rom.sh

adb.exe reboot

But after reboot command, my stratos is still shows the "A" logo, nothing more......

Where do I did wrong ...... :crying:
