Unbricking impossible.

I do all the things you say on the tutorial, which I truly appreciate, but unfortunately the watch didn't revive.

I have a Stratos 3 A1229, with locked bootloader.

I restart the pc to install the Ingenic unsigned drivers, start the tool and flash the four files you mention with the exact options.

I firstly try to flash the lastest firmware and the lastest OTA (4.2.8.0 firm and 4.2.3.0 OTA) , which are not subsecuentially like the ones you mention (You mention firm 2.3.7.0 and OTA 2.3.6.1 to 2.3.7.0). Anyways I try to flash the subsecuentally firm and OTA on your example and got the same error.

I'm stuck on the final stage, the watch restarts after what it seems a correct flashing and then seems to loose the connection as libusb-win32 (Can't find any USBCloner device) to connect to pc as USB composite device.

I can't connect the watch on Force erase mode until I close the ingenic app, which means that I have to flash another time, losing the advance done and getting stuck another time on the point that shows the screen capture I attached on the link.

Hope anyone could help me, got the Stratos bricked on a firmware update crashing.

I appreciate the hard work you are doing for the community!

您好，先生，我有一个问题：我的Huami运动手表2无法正常工作。

通常被卡在徽标中，

十分尴尬

我在论坛上寻找了很多案例来分析，但没有得出好的结果。

我尝试用烧录软件来获得更好的结果，可是手表任然无法开机，无法连接到电脑并完成刷机！

A.设备管理器上显示获得一个叫：JZ4785 USB BOOT Device的设备

B.烧录软件的uboot，boot等4个选项都无法正确的选择到。它也一直不工作！

请先生给我一个完整的资源让我完成恢复，我万分感谢您的帮助！谢谢！

I just did a successful cloner update om my bricked Stratos 3. The watch seems to function as it should but when I connect the watch to my computer I can see my my watch as "Amazfit Stratos 3" but when I "klick" on the unit it doesn´t have any visible folders inside. No visible root directory to put music or watchfaces in. Am I doing something wrong?

Thank you very much for the programs and this forum to help me unbrick the watch. (y)

try to connect to it via adb and check if you have sdcard or some internal mount access.

I pushed in and pulled out the USB-contact fast four times in the computer and suddenly I could see the internal memory of the Stratos 3. So now everything seems to work.

Hello, I have a question how to enter the "force flash mode (erase mode)?" "Only what I was able to turn on is fastboot mode, it's about the amazfit pace watch, someone uploaded a stratos rom, bootloder blocked
[Amazfit] JojjanSwe:
I just bought a used and bricked Stratos 3 and I performed a deep flash using Ingenic clooner tool with the latest stock firmware 4.2.8.0. file from this forum. The result was a success. But I can´t tell if the watch bootloader is locked or unlocked. What can I do to see this? And after this deep flash, can I use the normal factory reset from the watch and also the normal OTA updates when they arrive?
[Amazfit] matrixios01:
Use this command "fastboot getvar all"
[Amazfit] dimoura:
Don't know if you still having this problem, but for further references:

1) The first Fix is quite simple, just keep pressing the power button till It went through the first session.

2) Is quite on try/catch, but you have to equalize your USB write/read speed with your clock. I found this config on the middle ground for lots of pc's and clocks, hope it suits you.

All best o/

[Amazfit] polikarp:
Just read and understand what the post says. The tools that you have to use are detailed there. Pay attention on details and try. The most difficult part for me was to enter in fastboot mode manually. After that, the steps aren't difficult.

[Huawei P20 Pro Questions & Answers] kiazand:
Hi,

I have a question for those who have had huawei warranty claim. I had a canadian p20pro L04 and i rebranded to L29 while I was putting in 9.0 it hard bricked. Ive tried everything nothing worked.

I gave it to huawei third party service centre and they told me that they can't fix it its a boot issue and to send it to huawei and call them directly, they also said that their system is detecting it as l29 which is not my orignal model.

I also confirmed that it is still being detected as l29 through fast boot I was unable to change it by flashing files for l04.

Now if i send it to huawei canada how likely are they to know that my bootloader was unlocked thus voiding warranty? I have locked the bootloader again fyi. What would be my best steps to claim warranty?

Thanks for your help

I have to say that this fingerprint reader sucks. I can barely get it working and may end up returning the phone over this. They should have left it the way it was because it is really bad.
[Samsung Galaxy S10 Questions & Answers] mzsquared:
Which S10 is that and do you have that factory screen protector film on?
[Samsung Galaxy S10 Questions & Answers] Deleted member 7436581:
It's also been suggested that you don't need to press too firmly on the display. Making sure you touch the right area, as well.

I have the S10+ and I have tried everything. It keeps telling me to press harder but it only works about 20% of the time. It's awful.

Did you update? The is a fingerprint improvement in the update.
[Samsung Galaxy S10 Questions & Answers] dboss007:
Having the same issues with the fingerprint sensor. Checked for an update almost as soon as I opened the box, but it indicates it's up-to-date so now I'm clueless. I'm continuing to play with it, but if I can't get some improvement it's going back.

Yeah I just checked on my unlocked snapdragon device and no update. I really hope it helps because damn, it REALLY disappoints me how bad it is.
[Samsung Galaxy S10 Questions & Answers] dboss007:
Hmmm... Thanks for the info. I do have the unlocked. That makes more sense because there's always an update for a new phone & there's no way Samsung would release this because the reader is atrocious!

Mine came with an update out the box but still was performing ****ty, i redid my fingers and it works tremendously now. I did notice my Verizon s10+ doesn't have the faster recognition option...or at least it not where i e seen it in other models

[Samsung Galaxy S10 Questions & Answers] oakleyguy89:
I have an Unlocked S10+ and got a random notification just now that there was an update to "Biometrics and Security." I never had many issues with the fingerprint scanner before but this update seems to make it much faster and not so picky as to be right above the scanner. I thought the update everyone was talking about was going to be in the system updates but it's actually in the "Biometrics and Security" area just a FYI.
[Samsung Galaxy S10 Questions & Answers] :
I have the exact same issue as OP. I've registered multiple fingerprints and it's really hit or miss. Light or firm.

This is going back with hopes that they refine it for the Note 10.
[Samsung Galaxy S10 Questions & Answers] isopure:
Not thrilled about it. Initially had that screen protector on when I registered both thumbs. Went out for a walk, it was sprinkling outside. Attempted to unlock 20 times, would not read at all. Took the dumb screen protector off and re-did the thumbs. A bit better, but still off at times. Almost like the environment has to be just right.
[Samsung Galaxy S10 Questions & Answers] Paninno12:
Definitely not perfect but I saw an improvement after the update and I still have the factory screen protector on.

A good idea would be to have the fingerprint icon always on, so that you don't miss the spot.
[Samsung Galaxy S10 Questions & Answers] laureanop:
Very disappointed with the fingerprint scanner. Both my brother and I have a very hard time with it, no matter what we try. This and the tediously slow recent scrolling are deal breakers
[Samsung Galaxy S10 Questions & Answers] Duncan1982:
There is a big issue with in display scanners, mainly user error or could be defective as these devices are produced in there millions.

Hear me out, I am not defending nor attacking the end user, what I am saying is there is a learning curve (muscle memory) as where to place your finger.

I say this as I have used Two Optical Scanners (Mate 20 Pro, Vivo Nex S) and with those I never had any big issues, in fact the Vivo Nex S (still own) unlocks fast and reliably. Why is this? I can even just rest my finger (don't have to press) and it unlocks. If you wish for me to do a video on this I'll be happy to do so .

It is if you have a perfect device (non defective) just a matter of getting used to the placement. I can't be that lucky with two optical that never honestly presented any issues.

I can't show the Mate 20 Pro (sold) but I'll be happy to show the Vivo Nex S & the S10+ when it arrives.

Mod Edit: Removed quoted rude material

Agreed. I don't believe for a second that people are making up the issues. Question is why is it not working for them when it's fine for others. Hopefully it's not finger/skin specific but configuration issue.
[Samsung Galaxy S10 Questions & Answers] MWlfrd:
I had the same issues and couldn't get anything to make it better. I have the Samsung screen protector still on. Found a setting called "Touch Sensitivity" under Display, turned that on and it's been perfect ever since.

I'm curious, but did you get a system uodate as soon as you set up the phone? I'm wondering if that was something that Samsung turned on for the screen protector but a system update reset that switch back to default off.
[Samsung Galaxy S10 Questions & Answers] senor360:
I have an S10+, factory screen protector on, update done and completed, and sensitivity is turned on yet I still struggle to smoothly get this to unlock using fingerprint. I've removed them and added them again, making sure to move my finger around to get all angles / edges, but still not working the best. I'd say about 20% like someone else posted. That was one of the main features I was hoping to show off, but won't be doing that anytime soon.
[Samsung Galaxy S10 Questions & Answers] EVOme:
It was taking too long for me, so I enabled face unlock as well. Now I use both. Face unlock is so quick I rarely need to use my finger. I took the update and reregistered my fingers after it. Seems to be working. I think my problem, with the screen off, is not placing my thumb in the right place.
[Samsung Galaxy S10 Questions & Answers] Tel864:
I'm wondering how many have just pulled the Samsung screen protector to see if that's the problem. I've never used a protector and through the dozens of phones I've used I don't recall ever having a scratch. If I have this problem when they eventually ship my phone, I won't hesitate to yank the protector.

That made a difference plus the biometrics update. Much better now. Thank you sir.

Yes, I just got an update this morning as well and it seems much better.
[Samsung Galaxy S10 Questions & Answers] easyguy:
Your suggestion works better. I'm wondering why most dont have to turn that function on and get better result than us having to turn on the sensitivities? I might exchange for another one to see if it works better, but this might hurt the chances of me getting the earbuds.

---------- Post added at 05:44 PM ---------- Previous post was at 05:43 PM ----------

I know, I thought the "ULTRA SONIC" would destroy the 6T, but I was wrong, it went backward instead of forward. Hopefully I dont regret getting this phone more, than I do now.
[Samsung Galaxy S10 Questions & Answers] npthaiduong:
There is definitely a learning curve for using this fingerprint reader. It is different than the previous Samsung's reader, so you need to be patient and give yourself sometime to familiarize with its pace. I struggled with it initially, but I am getting better at one-click-open action with this fingerprint. The ratio is now 8/10 successful rate which is not too bad.

On the side note, for some reasons, my wife has almost 10/10 successful rate using my phone. She has never missed a shot, so I guess the issue is more about me than the reader itself.
[Samsung Galaxy S10 Questions & Answers] mike2518:
Return it man! Get a replacement, if it still sucks, dump this phone. My mate 20 pro even with an optical scanner is flawless. I expected more from this phone, things like these and the super slow charging are keeping me from pulling the trigger on this phone ugh
[Samsung Galaxy S10 Questions & Answers] Natureboy72:
I'm having the same issues also, kinda frustrating. Really don't want to return it.
[Samsung Galaxy S10 Questions & Answers] kool_am:
I was and still having this issue but one thing that improved my success rate was using lotion (on my fingers, lol). Apparently, dry skin can cause it to not work.
[Samsung Galaxy S10 Questions & Answers] gotnoypi:
I've had issues in my initial setup. I did turn on touch sensitivity and re-did the finger print scanning -- things are way better now.
[Samsung Galaxy S10 Questions & Answers] fOmey:
Anyone having issues should consider registering the same finger twice, be conscious about the position of your thumb while your registering.. I struggle to get mine to fail since doing this.
[Samsung Galaxy S10 Questions & Answers] chetly968:
I do a lot of gaming on my phone and run through the oleophobic coating in less than a month. This screen protector seems to have some coating on it so figure I'll use it till it wears off the take it off and continue naked. Will buy me some extra time, lol.

[Samsung Galaxy S10 Questions & Answers] Shuthefrontdoor:
My fingers are dry/cracked and I have a 1 out of 5 success rate so I had a coworker try and she had a 100% success rate
[Samsung Galaxy S10 Questions & Answers] whatsitsnamenow:
The fingerprint scanner is garbage. The only thing that helped somewhat is lotion. Even then it's about 40% success rate.

I'm not sure who in Samsung thought it was a good idea to place the fingerprint reader and power button as far away from each other as possible. They are the most used buttons and they both happen to be access by same thumb finger (for right handers at least). I now have to shuffle my hand all over the place to reach these buttons.

I already request a RMA return from Samsung.
