You could have been frustrated with all the features that’s supposed to be in your New Huawei Watch is nowhere to be found. Like Wi-Fi, Bluetooth and Language Selection are all hidden in the China Stable Rom of the Huawei Watch.
I have talked to the CSR of Huawei in China, they honestly told me that the Wi-Fi certificate for the watch is not yet certified that’s why they cannot unleash it yet but it is embedded inside the watch should future updates allows the Wi-Fi to be used. Regarding the language selection, local China release is locked to Simplified Chinese, whether you like it or not.
If you happen to buy from China or received a gift with a China local release Huawei Watch, here is the guide on how to flash with an English Rom which I have already tested mine on.
Here is the complete guide:
Step 1: Put the Watch to Fastboot Mode
1) Hold down the power button
2) The screen will go black for about 2 seconds and then boot into the Huawei logo. Keep holding down the power button.
3) Wait for the first vibration, release the power button and then immediately give the power button one short press.
Note: If you feel the second vibration, you waited too long to do the release and press. Start over again with Step 1.
Another alternative for Step 1:
1.) Install ADB SETUP V1.3
https://drive.google.com/file/d/0B_1zjuazXSqbQ0p6NWtvRk9OMzA/edit
2.) Enable ADB and connect to computer
How to Enable ADB:
- Go to About
- Click 5 times on Build Number to access Developer Mode
- Go to Developer Options
- Enable ADB Debugging
3.) Go into command prompt mode
4.) Reboot watch into Fastboot mode using this code:
adb reboot-bootloader
Step 2: Unlock the Bootloader
1.) On command prompt mode, type this command: Fastboot Oem Unlock
2.) accept the prompt on the watch.
Note: If successful, command prompt will say your bootloader is already unlocked.
Step 3: Flashing
Download first the three files before proceeding:
Boot Img: https://mega.nz/#!rgRQHRrb!lgQCvqH-qkuqitPRRXfCad29MdmJ6ynaUHJDr0hjeLM
Recovery Img: https://mega.nz/#!ahgjxA4R!y8Hb0CBVBRwUr0tA3HeFrrqh0ALAiMyqJu0pLsBsAD8
System Img: https://mega.nz/#!2pYVBDpA!wQJT8LDcffk7uxEmrsqna6MKWIODD-FqBO_k4Poml7g
After downloading the three files, lets proceed:
1.) While on Fastboot mode, type this on the command prompt one at a time:
Code:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
2.) and then go to recovery and do a wipe data / factory reset.
Congrats! Your done!
Further Reading if you are stuck on flashing System.img
There are some reason beyond my explanation why the system.img cannot be flashed to the watch, here is the workaround:
1.) First of all download the TWRP and fastboot boot it:
TWRP download: http://forum.xda-developers.com/attachment.php?attachmentid=3505656&d=1444766757
Code:
fastboot boot TWRP2.8.7.0-Sturgeon.img
2.) Now your watch is in TWRP and you can no longer use ADB commands, go to your watch and select Advanced, then select ADB Side Load
3.) Going back to command prompt, push the system.img in the sdcard so:
Code:
adb push system.img /sdcard/
4.) Now flash it:
Code:
adb shell dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
5.) Reboot.
Now you may encounter bootloop after flashing which I did, go back to Step 1 Fastboot mode and select Reboot Recovery, then wipe data and then clear cache, then you are good to go!
This is the most complete guide I can come up with based on my own explorations. Hope this helps.
Where can i find the drivers for this watch.
When i plug this watch into my computer Windows doesn't detect the drivers. I've tried looking on the HuaWei website but there are no downloadable drivers. Any help?

Look here : https://m.reddit.com/r/hwatch/comments/3n9ckp/how_to_get_adb_access_over_usb/
"Fastboot Oem Unlock" should be "fastboot oem unlock" otherwise it won't work. Also make sure to have ADB 1.0.32 at least for watches!
hello!
i do all step and complete flash with twrp mode . but when reboot and will go to reboot recovery the watch restart and restart!
sry for weak english!

Hi, first of all thanks for this awesome guide.
This is the first thing I am looking for after bought a Chinese watch from China.
Manage to go through ONLY I tried key in "fastboot oem unlock' all in small letters.
Then follow the guide instruction to goto recovery to wipe data after successfully go through the other flashing steps smoothly.
This is where I got stuck in infinite looping in Android lying and screen flashing every few seconds. I got panicked after trying multiple times failed to recover from this symptoms for a while.
Until finally manage to pull back to fastboot menu by keep press holding onto the power button. The steps of holding till first vibration then do a quick short press doesnt work.
I am glad that now I am back to normal with the English screen.
Next I will proceed to flash the TWRP and 1.4 update.
Hopefully everything goes smoothly.
Thank you for the guide once again and wish everyone success in updating and Enjoy!
Update: (9:29am)
Did a system update. Before was something like LBC49A, after system update it becomes LBC43B. I suppose this is 1.4 update as the name is the same.
Hence decided not to flash the TWRP recovery for the time being if it can continue auto system update.
Update (9/3/2016):
Sorry, nvr read through all the posts. Was thinking that (LBC43B) was the latest update.
So proceed to flash TWRP recovery then try to update to MEC23L (latest update) but failed to run "adb sideload update.zip"
Every time once enter into Recovery mode, the connection dropped. Then tried to do OTA update by factory reset as suggested but failed (confirmed my location can OTA as one use from same location didi it.)
This morning went back to PC flash back the original Stock Recovery from here.
Restart the watch and goto System Update, receive message "Charge the watch to update to MEC23L"
My thot - OTA only allow with Stock Recovery?
Update done but still cannot sms. ??
Btw, for LBC43B, many functions cannot work properly like sms, call and no sound at all. Thx n Enjoy.
P.S. Using Minimal ADB and Fastboot, PDAnet driver(for watch USB driver), running on Win7, connect via watch USB charge docking station.
help me please
No OS installed! Are you sure you wish to reboot?
This is my problem, I can´t install it-
I send you a private message Richboy234, can you help me please?

Hi there
All i know is you can flash the stock rom then update via OTA
mine is running marshmallow already now MEC23L
This is the safer way coz i never tried to flash in the MEC23L

hi there
i think you need to do a further reading on the one after step three
there are chances that you will get stuck in flashing the system image file
there is a workaround.
try it again
hope it helps.

Hello,
I'm also encountering this error. I did try the first method, and I'm getting stuck on activating ADB Side Load. Any tips?
Hi, there's a problem and i can't mount partition /data and /cache
plz help
Thanks a lot man you are a gem
I in hurry formatted system from twrp and was without OS. very detailed tutorial for beginners with adb. I am back with watch booting fine now
Just a note. I tried doing this while in China without vpn access for my phone. This made it so I couldn't sync up or pair because it kept trying to access google which was blocked. Once I got back to Canada I was able to do everything and update to newest OTA. If you leave it on chinese rom you can use in china and pair with the Android Wear China version app.

Not sure if he got back to you. I had the same problem, and it involved the system.img that I downloaded from the link above. It wasn't complete for some reason. On this thread attached, it has a zip that has it all. My watch works fine now. I want to thank the OP here for showing me the steps to take. You all ROCK!
hi all, sorry if this has beeen posted before but its bugging me as i spent literally 4-5 hours lastnight trying to sort it, i havee rooted 4-5 android phones in the past but im just having no luck with this one
i installed adb / fastboot minimal, enabled what needed to be enabled in developer options on the swift, booted the swift into fastboot mode, then when i run adb on my computer, the first command works 'fastboot oem unlock' but after that its constantly saying 'waiting for devices' whenever i try the next phase of commands ie. fastboot -i 0x2970 oem unlock-go etc it just wont detect the device at all in windows on adb, is there any suggestions anyone could throw out there before i end up sending it back and getting an alternative android phone thats easier to root? the only thing i can think off is its a usb driver issue? but i installed the gloogle usb drivers and it picks up the phone for file transfer etc so im not sure if this is the issue. many thanks!

Hi,
I had the same issue. When that happens, do commands without the -i 0x2970 bit. So for example:
fastboot -i 0x2970 erase recovery
becomes:
fastboot erase recovery
Hope this helps

I tried this but it still says 'waiting for any device' My initial command worked for fastboot oem unlock, but then I just couldnt do the following commands, and as a result whenever i tried to install a custom recovery / rom it gave me the error along the lines of 'unable to verify....'
edit: when i missed out the -i part, then said its already unlocked. however i still am not able to install supersu or the recovery as it still gives me the error 'signature verification failed'

Hi,
OK, what recovery are you trying to install? I would recommend TWRP 3.0.2 by Beroid (in the development section) because it's easy to use and it works. Get the image and put it in your adb folder is. Make sure you are in fastboot. Then run commands
- fastboot erase recovery
- fastboot flash recovery (name of file).img
Disconnect the device from your computer. Then remove the battery. Then replace the battery and press VOLUME DOWN and POWER to rebbot in to recovery mode to verify the installation.
You should now be in the recovery. You can flash custom roms and supersu within this new recovery.
Hope this helps

Hi everyone,
I´ve been trying to install twrp recovery in my Huawei Ascend P6 via fastboot. I followed this "techglen adb and fastboot guide"
I already installed everything needed for adb conection.
So I connect my phone in MTP mode and use "adb devices" and my device appears normally, but the problem happens when I reboot into Bootloader/Fastboot mode and use "Fastboot devices" it appears a device conected but with a bunch of "?????" and a smiley face at the end like this:
C:\Fastboot>adb devices
List of devices attached
123456789 device --------> bunch of numbers appear normally
C:\Fastboot>adb reboot bootloader --------> Phone restarts into bootloader mode (shows huawei ascend logo)
C:\Fastboot>fastboot devices
????????_?_???_?<??????? fastboot ----------> WTF (this is exactly what appears)
I would like to know if there's something wrong with my phone
Should I proceed and flash the custom recovery?
I have stock android 4.4.2 (rooted with kingroot) and stock recovery.
I am a total noob at this so I need your help :crying: I dont want to do anything stupid. (If already did let me know lol)
I have the same issue. Problem is that phone is bricked, so I can only enter in recovery (official, unrooted, unlocked) and fastboot mode.
Have you managed to solve or have some hint?
I have experienced a inconsistency while using minimal adb and fastboot. While device not showing i could send command and the phone would respond. After going into bootloader and while my device wasn't shown in the list i could flash twrp without much trouble, helped me go back from being stuck on bootanimation. used the command fastboot flash recovery xxxx.img (where xxx is the name recovery name). If you can get into boot loader try fastboot reboot bootloader and if the phone responds you might be in the same situation i was.
Always remember: Messing with recoveries bootloaders and boot images might make your phone unusable so do it at your own risk
Have you actually tried to flash twrp? Did you put the img file of twrp to the minimal adb and fastboot folder? If so, try the commands 'fastboot flash recovery recovery_twrp.img(<-- use the name of twrp file here, so not the exact name wrote here) and reboot. My phone is a bunch of question marks as well and it flashed twrp just perfectly (I got it frome here: http://forum.xda-developers.com/showthread.php?t=2632542)
my device came with unlocked bootloader, so I tried to flash twrp but every time i type "fastboot flash recovery C:\adb\twrp-3.2.1-3-whyred.img" and hit enter, the device seems to disconnect from pc and there is "press any key to reboot" in fastboot on my phone.
How can I solve this issue?`
Phone gets detected by adb/fastboot tool so its not a driver problem. I tried different cables and usb ports aswell.
Firmware is latest global stable.

Well if you already had adb in your pc, rename the twrp file to recovery, you don't have to move the twrp from download folder, open download folder press shift and right click then select open cmd here, on cmd type "adb device" to see if your device connected, then after that type this "fastboot flash recovery recovery.img" press enter than after that type "fastboot boot recovery.img" TEAMWIN logo should appear on your device and then you can unplug your device. Hope this useful
i am trying to flash twrp there is no folder called adb i have installed the 15 second adb and all so i have got this minimal adb flashboot and i tried with that and got this ---- FAILED (remote: Flashing is not allowed in Lock State). i have granted all usb and oem unlocking. please help with this
Phone shows unlocked during the boot?
I had the same Problem,after a Factory Reset works for me.
I am on Miglobe-Rom Miui10 8.6.28.
Minimal ADB is enough.
Or use this from Attachment.
Unpack with Win.zip and copy Twrp in this Folder.
Conect the Phone with your Pc ,boot into Bootloader and click "cmd-here.exe"
Use this Command
fastboot flash recovery twrp-3.2.1-3-whyred.img
@Nazukii - Quick question - any chance you could try running GameBench on your device, and see if our background service dies when the device is disconnected from the PC? I don't have a Note 5 Pro to test, and I've got some user complaints. Any assistance would be awesome!

My phone stuck in MI recovery idk how.
I cant install MIUI via fastboot. Im stuck ..
Can anyone please help me here not sure how to proceed further.
If you have made sure that you have all the drivers installed and still have not solved, you need to use an Intel-based PC / notebook and use a usb 2.0.

Fastboot boot recovery.img flashing problem on Redmi note 5 pro
My bootloader is unlocked and my oem as well as usb deb is on. After i connect my phone in fastboot mode to my pc. The cmd shows fastboot devices but when it comes to fastboot boot recovery.img flashing device get disconnected. Plzzzzzz let me know a solution for this. A solution for this will be highly appreciateable.
I got a brand new AT&T's Moto Z2 force XT1789-04 (updated to Oreo using an AT&T SIM) and got it SIM unlocked through unlockstone.com's service. After the unlock, I found the following problems:
(1) After every reboot, the device first goes to the fastboot interface (Android man down with box open, just like the figure below but shows "Start" on top right instead ), and I have to press power button to continue a normal boot.
https://www.hardreset.info/media/re...fd1b9659973ee877f48/motorola-moto-z2-play.jpg
(2) In fastboot, If I choose "recovery mode" using volume down/up and press power button, it will go back to the fastboot interface with "start". In another word, I can't see menu of recovery mode, such as "wipe data/factory reset", "Apply update from ADB" and so on.
(3) In addition, the model number has been changed from XT1789-04 to XT1601, but it shouldn't matter according to discussions of other unlockstone's users.
My first questions is, can anyone help me to explain the reason and possible fix to those issues? Would a flash of official AT&T's firmware (such as, NASH_ATT_OCX27.109-47_subsidy-ATT_regulatory-DEFAULT_CFC.xml) be able to fix it?
I understand AT&T locked the bootloader, but it is still possible to flash the firmware, according to:
"With a locked bootloader you can flash an official firmware that is the same revision or newer. So in short, yes." (see, https://forum.xda-developers.com/z2-force/help/updating-att-ota-issues-help-sideloading-t3864514)
So, I gave it an try on my Mac (I also tried on Windows 10, see below):
(1) install moto device manager (MDM Intaller_2.2.9.dmg) downloaded from moto
(2) install 15 second adb and fastboot installer (adb-setup-1.4.3.zip) from XDA
(3) copy files unzipped from (2) to a working folder, copy the firmware as an update.zip file to the same working folder
(4) turn on the device, open developer's options, turn on USB debugging
(5) connect the device to the MAC, choose "USB for file transfer" mode
(6) open a terminal and type the following commands
$ adb devices
List of devices attached
ZG224AGZPZ device
$ adb reboot recovery
Both work fine.
(7) Now the device is in fastboot's "START" mode, not "recovery mode". Since I cannot Select "Apply Update from ADB" from the device, the following command certainly failed:
$ adb sideload update.zip
adb: sideload connection failed: no devices/emulators found
adb: trying pre-KitKat sideload method...
adb: pre-KitKat sideload connection failed: no devices/emulators found
My second question is, can any help me how I can flash the device if the above methods doesn't work?
By the way, I also tried several methods on Windows 10:
(1) Similar to the above method, install moto device manager/or install moto USB driver, install 15 second adb and fastboot, open a CMD window, but "adb devices" couldn't find the device.
(2) Use Lenovo Moto Smart Assistant to "rescue" the device. However, since the device's model number has been changed from XT1789-04 to XT1601, it couldn't go through.
Any suggestions? Many thanks!
Sounds like you have fastboot mode set on, most likely didn't clear from update.
In fastboot enter 'fastboot oem fb_mode_clear' w/o quotes then 'fastboot reboot' and you should boot normally.
When you flash an update, you do it from fastboot, not recovery. When you sideload, you do it from recovery.
Great! The first problem (automatically paused at fastboot interface) is fixed! Thanks a lot!
This is what I did:
(1)
$ adb reboot recovery
$ fastboot devices
$ fastboot oem fb_mode_clear
...
OKAY [ 0.008s]
finished. total time: 0.008s
(2) fastboot reboot or reboot the device manually, it will be brought a fresh start asking for account setting and so on.
In this step, the device got stuck at AT&T's Logo and "Checking for update", but can be solved by manual reboot.
(3) Soft reset works (Setting-->System-->Reset) and will show an "Erasing" screen during reboot.
Then a new but famous problem comes up: When use power+volume down to enter fastboot mode and then use volume key to enter "recovery mode", it shows a down Android robot with red exclamation mark + "no command" other then a menu of options.
There are multiple methods available online. What works for me is:
"it worked when pressing power button for 3 seconds then preesing volume up and released both together"
Then select reboot the system.
It can't remove the Android+Red exclamation+no command screen under the recovery mode but at least provides a method to access it.
However, I have to try it a couple of times before it can show me the recovery menu. I don't know why.
According to this (https://forum.xda-developers.com/z2-force/help/z2-force-booting-to-blank-screen-t3808222), this problem might be able to be fixed by "You should flash it back to stock.".

I'm not sure what issue you're having. What you're describing is normal. In Nougat whenever you rebooted to recovery it went to recovery, in Oreo whenever you reboot to recovery you hit a post screen. When you see the android with 'no command' just hold power and tap vol_up, that will bring up the recovery menu like normal. That's the way it is.
XT1789-04 won't boot
Ok, here's my story. I have the very same problem here with the very same phone. Moto Z2 Force XT1789-04 from AT&T. Sim unlocked with same method as they unlocked yours. Converted to XT1601. Can't use Moto Assistant as it will find the mismatch.
Tried the fastboot commands shown here but looks like my problem goes deeper. I'm stuck on a black page that says "Your device is corrupt. It can't be trusted and will not boot. Visit this link on another device...."
Looks like they flashed a custom file or something and of course the boolotader is not unlocked and can't be. What are my chances of fixing it here?
