Unlock bootloader on a brick Amazfit Stratos? - Amazfit

Hey, sorry if i bother or im posting where im not supposed to.
I have an amazfit stratos that has worked perfectly for years, but suddenly it got brick two weeks ago, I've trying to fix it lately, but I have no clue on what shpul I do.
I have installed the Adb libraries, Minimal Adb and fastboot and followed tutorial of some threads but I always get the same error, when I put the watch in fastboot mode it is recognized by the computer on the device manager, but whenever I try to execute the adb commands, it says that theres no device attached, I dont think I have a problem with adb libraries because it can recognize my other devices.
I've installed the "TOOL ALL IN ONE" and Huami AMAZFIT Tool of mauronofrio to try to install a ROM or at least get an idea of what could be happening, both of the Apps say that the device is in fastboot mode, but none of them can recognize the device, also when i click on check bootloader status it says its locked and whenever I try to unlock it the watch would restart getting stuck into the logo so the app throws an error.
I dont know if my problem is that the bootloader is locked or if Im doing something wrong.
Id take whatever advice, thanks

HP 7 VoiceTab 1321RA Bricked without Recovery or Custom Recovery mode accessable

Hi!
First off let me say thanks to R_a_z_v_a_n for redirecting me and hope that I'll find my answer here ^^
So I Have this device called HP 7 VoiceTab 1321RA (not with Slate just HP 7 Voicetab), wanting to have a custom recovery then I tried to flash a CWM Custom Recovery for HP Slate 7 VoiceTab because I thought it was the same and ends up bricking my phone. It ends up in a bootloop which only shows HP sign for a few seconds and dead. But I managed to find out that I can access the recovery menu (or so I thought it is), but the options was choosing between Fastboot Mode, Normal Boot, Recovery Mode, and VART Mode.
I tried to enter Fastboot Mode before and tried to access it via PC but somehow I can't find the device by entering adb devices and fastboot devices. Anyways, I have downloaded a stock update.zip for it but not the original KitKat one which I get from the first time I bought it but rather the JB ones. I think by flashing this would help me recover the device but the only problem is I don't know which method should I use to Flash it. Since I don't have the Stock Recovery or ANY kind of recovery at all, I guess I'm stuck. And it won't start to the home page so I can't set the USB debugging options. Please guide me through this >.<
Thanks a lot!
Been fighting with it for 2 days now and still no result came.
So here's the update so far....
I tried on my other device in order to understand how my PC reads ADB and now I kinda gets it. But the problem is now can't get the device to enable USB Debugging because I can't access options at all.
Secondly, since I left it on for the night because charging seems to trigger the bootloop too, now I can't access the fastboot mode like I was last night. And it constantly repeating this sequence: [battery scene with the "charging battery" symbol] > [HP Powered by Android screen] repeated for 2-3 times > [low battery need charging screen] > repeat. And once I tried to connect to the PC, it goes to the same sequence too. When I tried to access the boot options (the screen which displays Fastboot Mode, Normal Boot, Recovery Mode, and UART Mode which I mention in Thread Starting post), it shows the low battery need charging scene and then repeating the same sequence as mentioned above.
I seem to figure out how to fix this but I still can't manage to access the fastboot mode yet. Will give update once I can try to.
Anyone can help me on this?
Thanks a lot!
Update!
Somehow with a little tweaking and stripping the device, I managed to solve the charging problems. Will update on this once my problem finished.
Jump out from the frying pan and into the fire so they say, I ran into another problem. Finally managed to get into fastboot mode, the devices manager reads it as an Android Device>ROMaster ADB device like the other device I tried to connect while in ADB mode and fastboot mode, but somehow CMD cannot read the device as an ADB device or a Fastboot device like the other device did. I tried to uninstall and reinstall the driver and still nothing happens. I tried to find the usb_driver on the internet and it directs me to the update.zip instead. Trying to update the driver via Computer Management but it says the driver is up to date. Now thinking about making an emulator device based on the HP 7 VoiceTab 1321RA but I really have no idea how to make one. Any one have any idea of what should I do next or can guide me through this? At least until the CMD can read the fastboot.
Thanks a lot!
I found my self in a deadlock!
PLEASE HELP :crying:
Could you unbrick yours
What service centre says about that problem i also ran in this problrm but i m trying to go to service centre for that
first off install drivers in your PC as admin
then use the official flashtool to flash ur stock firmware by entering fastboot or flashmode simple as that
@Sunderesh, thanks for the suggestion, however, couldnt get any official flashtool for hp voicetab. Can you suggest one please?

[Q] Interrupted flashing process

Hello friends,
I was using a General Mobile etab4 tablet,
rooted,
bootloader locked,
not backed up, i tried but apps wont recognize the brand,
the stock rom is not available anywhere but I managed to find some custom ones.
This tablet is actually a given by government for educational purposes, and it has no download mode, I can only initiate recovery mode with volume up+power button combo, and there is no sd card in it.
Here is what happened. It was running with problems so I decided to flash a custom rom I find on this forum. First I tried flashing using adb sideload. I got an error message "Installation aborted" with no error codes after verification step but it does not state whether verification is failed or not. I don't know what actually failed. Then I tried to flash it using adb shell as root (the system image was in /sdcard directory). It freezed, I exit the shell using Ctrl+C command. Then whenever I try to start shell i got "error:closed" message. I see my device with adb devices with sideload, but it is not seen in fastboot devices.
When I try to open it, I guess it enters in a small boot loop (screen flickers multiple times with brand name on it) and after some time I got dead android with no command written.
I tried,
reflashing it again with Android AIO Flasher,
use fastboot to unlock bootlader (it says "waiting for device") although adb devices sees it,
re-installing the adb drivers after uninstalling them,
disassembling the device to see if I can detach memory to edit it and to see if disconnecting the battery helps,
I even used a simple jig to see if i can initiate download mode (know it works for specific devices but you know hope)
Apparently, I messed up the device but the hardware must be all fine. So I think there must be a way out. What can you suggest, I wish I have unlocked the bootloader. I can send the pictures of its motheboard it helps,
Thanks in advance.

Bricked Redmi note 3, please help.

The facts:
-I'm an idiot and I dun ****ed up.
-I'm a fool to believe I could power my way through learning how to flash roms and unlock the bootloader unofficially.
About the Device:
1: Kenzo.
2: I can access Fastboot (PWR +Volume down)
3: When I try to boot the device, the Mi logo is visible for 3 seconds, disappears, reappears again and then then the phone turns off.
3.a: When connected to my computer via the official cable, the screen remains pure black and the red light blinks repeatedly, as if in EDL. In device manager, the phone reads as "Qualcomm HS-USB Diagnostics 900E (COM10)
4:XiaoMIFlash and MiFlash tool both do not detect the phone when I hit refresh (which is why I can't seem to fix it)
5: Putting the device in Fastboot and attempting to send any command through CMD/ADB results in either nothing happening, or <waiting for device> showing up, and then nothing else happens. (This used to work before)
6: I don't believe I can access recovery (PWR+Volume UP)
7: Could not unlock bootloader officially due to getting stuck at 50% with "Not connected to Mi Phone" error.
I ****ed up. Bad. I really need help. I tried following many tutorials, but all of them assume that the device can be detected by MiFlash, but mine can't.
Please, I desperately need help. I'm new to android and if I can somehow manage to get this fixed, I'm keeping MIUI, to hell with custom roms, as long as it works.
Please help, I'm at my wit's end.
PS: If the only possible way to fix it is test point method, please post the name of all tools I need, so I can go and buy them.
PSS: Device bricked after attempting unofficial unlock. I never got to the "OEM unlock" part, it bricked before that.
PSSS: Before bricking, I was using China Dev rom. As to try and avoid bricking the device, I switched using miflash to kenzo_global_images_V8.0.5.0.LHOMIDG_20160805.0000.29_5.1_global.
Then, following the unofficial unlock tutorial, I tried flashing the same rom with the modified prog_emmc_firehose_8976_ddr, and it bricked there.

Have your phone boot into fastboot. Connect your phone, run adb and check if it receives commands by using : "fastboot devices". If it returns a value then your phone is detected on your computer. Next, download this file : https://www.androidfilehost.com/?fid=24591000424940129
Now, extract the zip file and open Reboot.bat . This will open cmd and press the enter key.
Your phone is now booted into EDL mode. Now MiFlash should detect your phone and you can flash a stock image from the Miui forum. Probably best to to flash stable ROM (fastboot ROM).

So far, I've managed to successfully boot into EDL by unplugging the battery and USB. Now, I just need to figure out why Miflash is giving me a "System can't find path specified"

Make sure that you've disabled driver verification signature, your path to the image folder does not contain any spaces, and also the flash all data except data and storage option.

device unrecognisable in fastboot

so my phone got the bootloop problem, a few days ago and after hours of research i found a thread here with a kernl to solve the problem, so i went ahead with the guide and had to unlock the bootloader, i tried LG's site but it seems the site is faulty and i cant get past the log in screen, so i found another guide using fastboot, but fastboot wont show the device, i tried "adb devices" showed nothing, "fastboot devices" also yielded the same result, even though i hear a sound when i connect the phone in fastboot mode, some other research lead me to believe that there is a conflict in drivers because in the device manager it shows android with a triangle next to it, i tried different drivers, nothing, i tried using Microsoft update online but it found nothing, can anyone provide help? cant go to lg bcause i got the phone used, and done have the money to get a new one, so if i could this one back up and running it would be a dream, thanks for any help in advance!

helpppp ...The System has been destroyed

i managed to delete twrp and when i did then it shows that the system has been destroyed and after restart it is stuck on
fastboot windows. i tried to connect it with my pc so i could install flash rom but it doesnt show up on pc after connecting to usb.
i dont understand what to do next... helppppppppppppppppppppppppp
I have been in this situation before but I'm not sure how exactly i got into it but I was also doing something to do with twrp. Anyway, whenever you encounter such a problem you need to provide as much information as you possibly can to help us help you. This way people are able to narrow down to what causes a particular problem. One question I have is how did you "delete" twrp?
Now for how I got out of that "system has been destroyed" problem. First off, I had already successfully unlocked my bootloader (don't know if you had). Also, the adb drivers were properly installed on my pc. What I did (at the "system has been destroyed" screen) was to let it sit there while connected to the charger for what seemed to be around 10 minutes and kept doing what I was doing and out of the corner of my eye I saw it rebooting and unexpectedly it went into fastboot. I connected it to my pc and it showed up in device manager and "fastboot devices" command detected it. I proceeded to successfully flash recovery with fastboot and then used "fastboot boot recovery.img (or whatever you have renamed your recovery to)" command. It went into recovery mode after which I copied rom via mtp and flashed it and it agreed to boot into system after the flashing was successful.
These may not be the exact steps I took but as close to them as I can recall (because I was bewildered at the thought that my phone was dead). I think the key turning point was to let it sit at the "system has been destroyed" screen for a while.

The thing is i dont remember actually exact process but i somehow managed to delete the twrp ..
the main problem is you said after ur phone got onto fastboot you connected it to ur pc and flashed official rom but in my case in the device manger or anywhere ... when my phone is in fastboot mode and i connect it to my pc it doesnt show up as connected not in device manager or any other place...this is the main problem....if only my device shows up connected i wouldve flashed rom way before anything...its been 1 week since my phone died ...i need help...i tried everything from youtube ...seems it doesnt work for me

Have you ever had your phone detected by your pc in fastboot mode? And if you connect it to the pc, does the computer play the hardware detected sound?
You need to rule out a driver issue. I'm not the only other person to get the "system has been destroyed" message and people usually get out of it. I don't know why yours is so problematic.
Had you successfully unlocked bootloader?
The Good old "System has been destroyed" Message. Well, This is terrible This should not happen in the first place. I assume it happened Because you wiped data and then deleted twrp. But If you want help you have to specify how exactly did you " Delete TWRP" What steps did you follow to Delete it. None the less the best bet on getting your device back would be to go to the nearest service center. Pretend you did nothing and maybe they will say you got a bad update.
