Not getting into Fastboot mode after setting fastboot oem unlock - Xiaomi Mi A1 Questions & Answers

My Device is bricked. One fine day, the mobile was not charged inadvertently and phone discharged to 0%. Later on connecting the phone to a charger, the phone did not turn on. When pressing the power button, the MI logo flashed and phone turned off. The hardware was checked by a technician; No fault was found except he said the Os might have corrupted. Flashing the device might turn it back on. But I didn't want to lose data, so I stopped.
However, the phone could be switched to fastboot mode by pressing the power button and volume down key.
I needed the data back so in an attempt to unlock the bootloader, I typed the command
`fastboot oem unlock`
The command prompt printed Successful. Finished in...,
the phone restarted but as it is, did not turn back on.
When I am trying to switch to fastboot mode it just doesn't blink or doesn't flash the logo as it used to do earlier.
However, the device seems to get connected to the pc. I had installed adb drivers and MI Flash tool.
The Mi Flash tool on refreshing identified a device with an id.
In this scenario if I have to turn on the fastboot mode and flash a custom rom and save my data, what can I do?

Bricked Storm

Hello, I have a problem with my storm. Two days ago I received it and flashed the then latest cm13 and its corresponding recovery. Everything seemed to work just fine until yesterday when there appeared to be an ota update. After the download finished, the phone rebooted itself and is since then stuck with a black flickering screen. Every attempt to start the phone using recovery or bootloader seems to fail, as the phone keeps showing me the black flickering screen, no matter the combination of keys (vol+/vol-) I use to turn it on. If during the black screen I plug the phone to the computer adb can actually see the phone but says it's not authorized to perform any command. On the other hand fastboot won't even see the device.
Is there anything else I can try before sending it back to wileyfox?
Thank you in advance
I've made some progress, I found out that the device can be forced to Qualcomm HS-USB QDLoader 9008 mode by turning it off and then connecting it to usb while holding vol+ and vol-.
I've also found the stock firmware at https://cyngn.com/support.
Now it would be great if somebody could help me, and the others in my situation, to figure the wole QFIL unbricking out, because I'm overwhelmed, and can't seem to find the right info on google.
Thanks to anyone who'll care to help, or share some info
I had a similar issue so have created a thread with stock recovery instructions, which resolved the issue for me.

Thank you for your reply.
Unfortunately this does not seem to be applicable to my case because on my device fastboot mode doesn't seem to work.
I've spent an entire afternoon trying to get it to boot to fastboot mode using different vol keys combinations and timings, but none of them seemed to work. No matter the combination, it just kept booting to a black screen flickering.
I'm starting to think that it could be some problem unrelated to my actions because if, as I think it is, recovery mode and fastboot mode are two separated things, nothing I did would justify this kind of behaviour.

Sorry to hear you are still having trouble, it does sound like the same issue, was a CM13 update from the last couple of days, upon reboot I saw the wileyfox logo but when the Cyanogen logo would normally show during boot it displayed a black screen, which would flicker every few seconds. Holding vol- and power to reboot resulted in the same thing so I was unable use recovery.
When the display was black and connected via USB I was able to see the device using ADB but like you no commands were authorised.
Leaving the phone plugged in via USB and holding down vol+ and power until it rebooted I was able to enter fastboot, once the fastboot prompt was displayed on the screen I attempted using fastboot to boot from a custom recovery, unfortunately that just resulted in the same blank screen for me. I also tried booting the stock recovery with the same result, I admit I did not try many older CM recoveries, but I wanted to revert to CM12.1 anyway, as the accelerometer and gyroscope not working in CM13 at the moment is no good for me.
Only thing that worked was a stock restore, so I think something beyond the recovery got broken as you could not even boot a previously working recovery.
For the sake of sanity it may be work getting someone else try booting it into fastboot before resorting to Wileyfox support. Though your phone is really new so could claim a refund or replacement from the seller, that would probably be faster.
FYI if you do end up sending it to Wileyfox support they do flash it back to stock, I had a broken screen replaced, was repaired and back to me in just under 2 weeks.
What would be exactly the timing for it to boot to fastboot mode?
Because I just tried (again...) to plug it to the computer while powered off, then it powered on on its own.
After that I rebooted it by holding together power and vol+ and immediately after it rebooted (right after the vibration) I let the power button go and kept holding the vol+ until the black screen appeared again... no fastboot

Hi,
Just tried a few combinations to check timings for you.
Powered off, not plugged in, holding vol+ while plugging in phone end of usb connected to computer, keep holding vol+ -> boots straight to fastboot.
Powered on, already connected to computer via usb, holding vol+ and power, release power when vibrates to indicate reboot but keep holding vol+ -> boots straight to fastboot.
Are you seeing the black and white Wileyfox logo when first booting? When going to fastboot it should skip that. If you are not seeing the logo it might not show the fastboot screen either. You can try following the steps above and then issuing fastboot devices from a command/shell session to see if you are in fastboot mode.
I hope that is of some help.
Thank you but I can confirm that neither of these combinations work for me. When rebooted/powered the device shows the wileyfox's logo.
If I use your first method it just seems to freeze on the wileyfox's logo screen, and the computer won't even see it (it's not listed on the usb devices list) so fastboot's not an option.
If I use your second method, or any other I tried, it shows me the wileyfox's logo and then proceeds to the black screen, which can be seen just by adb (not fastboot) but I'm not authorized to perform any action like you described for your issue.
I'm out of ideas so I'm sending it back and getting it replaced. On the cyanogenmod irc they told me that to brick it like that it cannot be done just by accident but it should require a lot of deliberate effort, and that just installing cm13 + recovery doesn't justify this problem nor does an OTA update, so it's probably some other (hardware?) issue with a very bad timing.
I'm kind of sure it's not the vol+ button that's damaged, because if I leave the device powered off and then proceed to plug the USB while holding together vol+ and vol- it powers on, but the screen stays off meaning the Qualcomm HS-USB QDLoader 9008 mode has been triggered.
Anyway thank you for your help, I could rule out my inability to start the fastboot mode and blame it on the phone xD
Hope I'll be luckier with the next one...

No problem, I hope you have more luck with the replacement.
Here I am again, new device, still can't boot to fastboot mode (this time I didn't flash anything, just unlocked bootloader so it's not bricked).
"adb reboot-bootloader" works, advanced reboot menu works, yet the vol+ combination hangs on the vendor's logo.
I'm contacting cyanogen os people to try to understand what might be the issue...
Could you please confirm that your device boots into fastboot mode when using the vol+ way? thank you

Hello again,
So these 5 methods work for me, someone else may have other experiences:
Phone powered off, hold vol+ while connecting USB, other end of USB already plugged into PC, continue holding vol+ until booted to fastboot (almost instant).
Phone powered on, already connected to USB, other end of USB already plugged into PC, hold vol+ and power until reboot vibrate, continue holding vol+ until booted to fastboot (almost instant).
Phone powered on and in OS, already connected to USB, other end of USB already plugged into PC, debug enabled, from ADB console, adb reboot fastboot or adb reboot bootloader
Phone powered on and in OS, advanced reboot options turned on, hold power, select reboot, select bootloader, reboot
Phone powered on and in Recovery, select reboot to bootloader
Currently I am running stock everything.
Perhaps try different USB cables or ports, though I still get to fastboot without the USB cable plugged in.
My Storm was a pre-order so is one of the first releases, it is possible they have changed something since.
Edit: I have come across a thread on the Cyanogen forums which implies this may be related to encrypting your device: http://forum.cyanogenmod.org/topic/117661-bootloader-hangs/ - I see you have been there already
as reference mine is not encrypted at the moment

DEAD Xiaomi Redmi 2

Hello, today i shutted off my xiaomi redmi2 and it shutted off normally.
But it doesnt start back again at all, i tried another battery and i tried charging the phone for several hours straight.
Testpoint method does not work and when i connect the phone to windows 10 pc it just keeps dissconnecting and connecting again several partitions (i think it is linux composite device, ive seen it in another snapdragon phones in the past)
Does anyone have any idea how to fix this phone ?
Btw at the time this happend i was on global stable miui, but the phone was previously running ressurection remix with stock kernel.
u have try to boot into fastboot or recovery?
if u boot in both then u can flash stock rom.. and fix this problem....
I assume you have Redmi 2 snapdragon variant since you have flashed global rom. Try to boot into fastboot mode by pressing Vol Down + Power. Download fastboot rom for redmi 2. Link
and minimal adb and fastboot Link
Extract the fastboot rom file with winrar (.tgz) and you will get a folder named "wt88047..........." inside that folder, there will be a subfolder named images. Extract minimal adb and fastboot to the wt88047 folder. It should look like this:
http://postimg.org/image/3r2hg2nhj
Run any .bat and fastboot process will start
Thanks for replies but it is completely hard bricked, i cant access recovery,fastboot and bootloader and the phone is not booting
Just some help

So if its not going into fastboot then it must be the battery's problem or (the one i faced)DEAD SCREEN...if you feel vibration but no display then its probably just the dead screen.
There's no solution for it at home, u have to visit service centre.
If you have a custom rom installed, then switch back to factory to bring back warranty.
As said before, if it vibrates but no display the phone's still working(just the display is gone). Reboot into fastboot mode by VOL DOWN+POWER or VOL DOWN and insert usb while keeping the button pressed.. then go to the folder where you have extracted fastboot.exe and then SHIFT+RIGHT CLICK> Open Command Window Here...a cmd window opens up the type in:- fastboot devices...
If there's an output then your device is connected.....Later reply to this if that works
Thanks i will try it
@Blazerstriker Thank you very much, the phone went to fastboot and i fixed it
Hi. I have same problem but get no output from c:\adb> fastboot devices. Pressing vol- and power does nothing. With phone connected to Windows 10 pc by USB I get connecting and disconnecting sounds over and over but phone does not show up.

Pull the battery out, put it back in and connect the phone to pc while it is powered off and when you are connecting it hold the vol-
That is the only thing that worked for me

Hard brick of Z5C ... can I save it?

Well, I did it this time.
In a valiant attempt to install a custom ROM, I erased every partition using fastboot,
Code:
fastboot erase system
fastboot erase boot
fastboot erase userdata
fastboot erase recovery
fastboot erase cache
Now what I meant to do here was flash a recovery, using
Code:
//fastboot flash recovery TWRP.img
but repeating this so many times over the last 48 hours, I did not do above and instead went quickly right into below,
Code:
fastboot reboot
The system rebooted as I told it to ... right into a black void of nothing. Now their is no 'recovery' image and no 'bootloader' image ... the phone is hard bricked, won't turn on at all, dead. I was so close to getting to the custom ROM! Is there any chance to get it back into recovery mode? or have I learned a $350 lesson?
Edit: Further research indicates it may be possible to force the system into fastboot using a USB jig. Has anyone tried this method?

When you plug it in while holding volume up what happens?

Nothing. LED flashes red every few seconds. The same response if plugging it in without holding volume up. Along these same lines, holding the power button on for a few seconds causes the small vibration haptic feedback to occur as if it is turning on normally ... but nothing happens the phone remains dead. Similarly, holding volume down and the power key causes a small vibration haptic feedback as it was booting into recovery ... but nothing happens the phone remains dead. I haven't seen anything on the screen appear, or the phone turn on it any way, since executing the fastboot sequence previously described.
Whatever you did, you should still be able to enter in flash mode and flash a stock firmware. And by this I mean full stock firmware, not a ROM.

Ok, that would be great. I would be thrilled to get the stock ROM back, at this point getting the phone to turn on at all would be a victory! Would you please describe precisely how to do enter flash mode with the phone in the current state? To reiterate, the phone will not turn on in any way (normally, or volume down + power to boot into recovery). The only life in the device is a slow blinking red LED when it's plugged in, and a quick vibration after holding the power button. The screen has not turned on in any way, or the LED shown any color other than red, since executing the fastboot sequence previously described.
hold power button + volume up and to force shutdown
and then hold volume up (or down, i don't quite remember) while connecting it to a pc (hold the button while connecting the usb cable).
If the led turns green or blue, congrats
The power key has nothing to do in this context. It is used only to boot into recovery or force OFF.
While holding VOL ↑, plug the USB cable to your PC to enter into fastboot mode (blue light)
While holding VOL ↓, plug the USB cable to your PC to enter into flash mode (green light, or maybe nothing)

Nothing. Device still unresponsive as described.
does your PC detect the device ? (new device sound notification)

No, the PC does not currently detect the device. All drivers are correctly installed as the phone was recognized accurately prior to the described fastboot sequence.
This is weird. I already erased everyting via fastboot too a while ago, and I could still flash it.
Just to be sure.... unplug all other "smart device" before anything (drivers can't handle more than one device at a time when it comes to FB or flash mode). Open the device manager and let it to the foreground. While you hold the vol down key, plug it and keep holding it until the device is detected. Don't expect any reaction on phone's screen, it remains OFF in both fastboot and flash mode. So, if the device manager reacts, you win.

I'm getting something here which is very encouraging! Executing your sequence causes the device manager to blink (refresh) as if it sees something, however no new devices are recognized in the tree. The phone LED goes to a solid green, reminiscent of a fully charged battery, stays on for about 30 seconds, briefly blinks red and then back to green, etc. The device manager is certainly reacting here it just doesn't recognize the device.
So here we are, you win. Because you have the "two", detection and green led. And if this state goes off after a certain time, it is normal. There is a kind of countdown and the device quits that mode if nothing is sent to it. You should be able to flash a firmware now with flashtool software.
Just ensure you have proper drivers installed properly (WinUSB drivers need to turn signature verification OFF before or Windows will block the installation)

Unbelievable! You saved me! I'm back up with the stock ROM and peace of mind to attempt the custom ROM process again. Saved me $350 ... thank you!!
That's great : )
It is almost impossible to hard brick a Xperia. If something goes wrong, remember flashtool ^^

I only can reach the Bootmenu. Bricked? What can I do?

Hi,
I'm not very experienced with those root things and followed a tutorial to do so.
I unlocked the bootloader, had TWRP installed and root. This worked. Now I wanted to remove Root and TWRP and go back to the original state. I couldn't find the stock recovery file, so I installed the P996A04V1.3.0B13_MR2_sd_ssl.zip via TWRP from the SD Card. Till here it worked. I could enter the stock recover and boot the phone.
Then Android wanted to install a security update. I allowed it and this is where the problem started.
The install process stood still on 25% for minutes. I thought it stuck and pressed and hold the power button to reboot that I can wipe the memory. But nothing happened. But the installation Process continued suddenly. I had the feeling that this power key worked like a skip key. So maybe it didn't install a file where it was stuck.
After the installation reached 100% the screen switched to black and nothing worked anymore. I couldn't restart the phone or anything but I think the phone was doing something cause it consumed electricity. When I checked the phone hours later I noticed it was empty.
I can reach the unlocked bootloader now, but none of the selections works. Doing nothing to boot or select Recovery lead to black screen and stuck. Then I have to wait until the battery is empty again. Fastboot, Power Off just restart the phone and I end in the Bootmenu again. I can't even fully charge the phone. As soon as it has enough power to start the Bootmenu appears. So I don't see the display of the charging process.
I don't understand how this could happen. I tried different key combinations when the phone had enough electricty to start. The phone always restarts and end in the bootmenu. Only when I press all three keys it's standing still on the ZTE Logo screen but as soon as I release the keys I end again in the bootmenu.
How can I force another Update?
regards
Let' start with the basic questions:
Do you have proper backup of your data?
Which Android Version did your Axon had before it went unusable?
You could try to reflash TWRP.
Boot your phone into bootmode.
Download a proper TWRP Image on your PC (https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547)
Open a cmd shell (press the windows key and type 'cmd' -> press enter)
Navigate to the folder where the TWRP Image is stored ('
Code:
cd C:\Users\[I]YOUR_USER_NAME[/I]\Downloads\
')
Type: '
HTML:
fastboot flash recovery [I]TWRP_IMG_NAME.img[/I]
'
Afterwards you could try to reboot into recovery mode.
I don't have a backup. But there isn't something imortant on the phone that I want to keep. I can do a full reset and reinstall, too.
Android must have been the latest offical availabe what's in the file. Was it Android 8? V1.3.0B13
The fastboot mode doesn't work. The screen turns black and the LED blinks red but only for a moment. Then the phone restarts and I'm in the bootmenu again. Windows doesn't recognize it as device.
Is there a way to force it to do an update from my SDCard without it needed to be connected to a PC?

I don't know of any.
But you could boot into EDL Mode (Press and hold Both Volume button and then press the power button) and flash a Stock EDL rom from the Download Center i have linkd before.
It's not visible for the PC. The only thing I see is the charging screen when its total empty and you can't even boot as. As soon as it has enough power to switch to the normal screen the bootloader appears and when I do nothing the screen turns black and nothing happens. I don't even know if it is charging. The LED is off.
Follow this guide to unbrick it and then use MiFlash and flash an EDL ROM

Fastboot Loop on stock ROM

Yesterday my device hardware buttons stopped working all of a sudden. I rebooted it using the scheduled reboot feature in the phone settings, because I had no other choice.
It automatically entered Fastboot mode and I can only reboot it by keeping the power button pressed (which now works), but it restarts in fastboot mode again.
I've never installed any custom ROM on this device, nor unlocked the bootloader. I've only used the stock ROM and updated it with official OTA updates from time to time, however yesterday there was no update I'm aware of.
How can I make it boot the normal Android system again?
I've found a partial solution myself: just keeping VOL-UP and POWER buttons pressed for about 10 to 20 seconds reboots it into normal Andoid system, however it still happens it goes into fastboot again when I reboot it normally. I know how to exit fastboot loop, but I don't know why it keeps entering it.
