Hi,
I am trying to see if I can spring an old Karbonn Titanium s2 back to life by installing a compatinble Cyanogen OS in it if I can find one.
I have ADB and FastBoot installed in my Windows 7 PC.
Now the problem I am facing is I just cant boot this damn thing into Fastboot mode.
So,When I do this
adb reboot bootloader
The phone simply reboots. Literally. Reboots.
On the other hand, commands like
adb reboot recovery
works just fine.
Its just the reboot bootloader command that isnt working, which is halting my endeavor at the very first step because I cant unlock a bootloader that is invisible and so I cant install a custom recovery in it.
Any Help??
Thanks in advance.
P.S: The device runs Android JB and is rooted.
Dear Community,
I got my Note 3 Pro Snapdragon Version today and I tried unlocking the bootloader, installing root and TWRP.
Unfortunately after I installed TWRP, WiFi didnt work anymore so I wanted to go back to where I was before.
i tried flashing the GlobalRom with the MiFlash Tool but somehow I'm now stuck with a bootloop.
The phone starts up and shows the MI Logo but doesnt go on. I tried booting TWRP temporarily via fastboot commands so that I can try to flash flashable zip files
but it doesnt let me execute "fastboot boot xyz.img" anymore because my device is locked.
I would really love to hear any solutions or ideas. I dont want any root or something anymore. If someone has an idea Im very happy!!!
thanks a lot in advance and tell me if you need any more infos

1. keep vol + and vol - pressed while connecting USB to enter adb mode
2. check if phone is connected with "adb devices" in command line, if phone shows up, enter "adb reboot edl"
3. now you can flash via MiFlash

First of all, HUGE thanks for your fast answer!
Unfortunately I couldnt get this to work. Since I am stuck at the Logog screen here is what I tried:
Pressing both volume buttons while Logo Screen and plugging USB.
Pressing both colume buttons while fastboot screen is up.
These two didnt enter adb mode, I guess because of the bootloop I'm in
I also tried antering recovery mode with volume up + power button. Pressing both volume buttons didnt help either but when I am in recovery like that it shows my device in adb as "sideload" device.
Maybe that helps ? Can you give further advice or am I doomed?
My idea would be: Is it possible to reflash the device completely only usinf fastboot? The only thing I seem to be able to enter is fastboot...
Is there a way from fastboot to "working phone" ?
or maybe through the "adb sideload" state?
thanks a lot in advance!
Paul
EDIT
tried installing via "adb sideload xyz.zip" command but after shortly showing a status bar on phone screen it aborted and said "Total xfer: 0.00x" on PC screen .
Also: I read "adb reboot edl" brings you to download mode so you can flash something. Tried it but the phone just rebooted the normal system, so it stuck on Logo again...
search miui forum for unbrick, there is 2 or 3 method without opening your device
exp: http://en.miui.com/forum.php?mod=viewthread&tid=257227
Unfortunately they all do not work because they always require either a phone in download mode, and i only get to fastboot and adb sideboard or they require flashing something via fastboot but I can't do that either because it says my device is locked if I try...
Any suggestions how to flash a ROM with fastboot only or with adb sideload?
Thanks a lot

I Had The Same Issue Brother ! There are only 2 Things which you can do now .
1. Test Point Method to enter EDL
2.Give it to Service Center . I Gave Mine to Service Center ,They Fixed it in 30 mins or less and it was free

Can I do the test point thing myself or is it risky?
What kind of service center? A general mobile phone repair shop or a Xiaomi special one?

I've been facing the same (or a similar?) problem about a week ago but managed to get out. Knowing me for having a head like a sieve I made some notes, sadly quite rudimentary
Did you try to flash with MiFlash after "adb reboot edl"? If I remember rightly after "adb reboot edl" you got the logo like booting another way, but the light is blinking red. Then I could flash via MiFlash.
I'm quite sure that if you get a "reboot" after entering "adb reboot edl", your phone will be in edl mode.
I will try that this evening when I am at home again and report. Thanks

Unfortunately this doesnt work. Phone reboots and shows MI Logo but red light doesnt blink and MiFlash doesnt recognize any devices.
Do you have another idea? :/
How did you unlock the bootloader, via official permission or that unofficial hack?

I didnt use the official way :/ Im so hoping my phone isnt broken. I wish i owuld have been more patient

Only options you have right now are:
1) using test points method which is a but cumbersome and voids warranty if you care about that.
2) go to a xiaomi service center of you have any nearby.
It is hard bricked.
So there is absolutely no option to unlock bootlader via adb sideload or fastboot ?

Apparently, no! Whenever using unofficial methods, read precautions carefully and you missed all as I can see. Wait if someone can help you out.
apply official unlock. then unlock your device from fastboot mode.

That sounds nice and easy. I already applied for official unlock.
But: do you know if u can use the official unlock now? I can only access fastboot and adb sideload mode. Is it possible to activate official unlock from there? Or do I need a working ROM rather?
I would have thought that official unlock doesn't work from fastboot /adb sideload...

I have the same problem. I made the same mistakes as shisaya24. I have followed every procedure for unbricking and nothing works. I even applied for an unlock code and got it from Xiomi. I used their mi-unlock app which requires fastboot (pwr/vol-) but it gets to 50% and bombs out. It states it can't verify the phone. Can anyone please help me??

out of sheer desperation I tried MiPhone again and after a few tries, MiPhone started updating the OS. My phone now works again and I have an unlock code as well.
Hi. I have a Amazfit Stratos with stock CN firmware 2.0.34.2 and I can't seem to get it to boot into fastboot mode. Whenever I run "adb shell reboot bootloader" in CMD, the watch just reboots normally. The watch is recognized by my computer in device manager. Just trying to unlock the bootloader. Any ideas what I could try?
Thanks!

How about this? adb shell reboot fastboot
If that doesn't work, then try this. https://forum.xda-developers.com/sm...tches/amazfit-boot-fastboot-directly-t3546829
What does the code below do?
Code:
adb shell
reboot bootloader
You can always use manual mode, as it's explained in Anox link.
Hi guys sorry for the delayed response. Tried both suggested ADB commands and attempted a handful of times to manually enter fastboot mode (according to instructions in link) and in each case it just reboots normally. Is there a debug mode setting that needs to be toggled beforehand or something?
I've also tried using the Huami Amazfit Tool app to reboot it into fastboot mode and it still reboots normally.

Fastboot mode should always be accessible.
That tool & others basically use the same command to access fastboot mode.
The manual method is supposed to be the last resort. I now have no idea, sorry.

If
Code:
adb shell reboot bootloader
does not work for you due to some reason, you can do it manually only: it uses the buttons and need some tries because it's tricky. It is the same process as Pace, search forum or YouTube for more info.

@vinny13 Did you solve your problem?
I have exactly the same problem.
When I try "adb shell reboot bootloader" the answer that appears is "- exec '/ system / bin / sh' failed: Permission denied (13) -
using port = 5555 "
Manually I've tried over 70 times and I don't know what else to do to get into this FastBoot ...
I think I was drawn!
Thanks for any help.

Using the button trick is the only way you have to enter into fastboot.

Thanks for your response, @Saratoga79. Has anyone seen any cases that the watch does not enter Fastboot or the button? I say this because the operating system of the clock was always crashing ... Now the only screens that appear to me are "A" and "No Command".
I will keep trying the button method. I confess it has been over 90 times.

I already found the solution, but it will erase your data.
with the adb commands you must restart the device in boorloader mode:
adb reboot bootloader
Then when I take you to the bootloader screen what you have to write next:
fastboot oem lock
(Remember the phone will be erased)
then to restart the device you have to:
fastboot reboot
And the device will reboot.
what you do is lock it, so that you can then unlock it in a simple way.
(If you do not know what the ADB is, warn man), I hope it helps you and those who enter here too :good:
@l3dson: Be careful before relocking the bootloader: The phone MUST be 100% stock or you will have a brick.
@Mohammedbi: Your bootloader is still unlocked, even after flashing the KDZ. It's just the newly flashed ROM doesn't know it, and you don't need it to.
Just go to fastboot (PowerOff, Vol- while plugging in cable) and flash TWRP. Follow ChazzMatt's root guide for the initial TWRP steps.
Have anyone found the solution for this problem...

What exactly is not working?
ADB doesn't require Enable OEM Unlock to be set. Just plug it in and ADB away - unless drivers or cable or port aren't working.
And your bootloader is still unlocked if it was unlocked before you flashed stock Oreo. You should be able to enter fastboot using the steps described in the post just before yours.
Edit: Of course you have to enable USB debugging in order to use ADB. I'm sure you knew that

hey i have this same problem and been asking around... but the adb reboot command will not work because it says the phone must be "enabled oem unlock" mode before you can use adb commands... which is greyed out..so back to square one... how to enable it?? any suggestions on this??
I am trying to root my OPPO A72. After successfully configuring the adb and USB Debugging I was trying to fastboot it using 'adb reboot bootloader', because 'adb reboot fastboot' reboots it to recovery, which I do not want. After rebooting the phone using 'adb reboot bootloader' for half a second there is chinese text with the text 'FASTBOOT', then it just reboots the phone into android. The OEM Unlocking option does not help. Any ideas why that is / how to fix?

The A72 cannot be rooted at the moment.
with phone on if you enter adb reboot fastboot , it takes you too a screen similar to the recovery screen but you can access phone by fastboot devices etc ... BUT it's a very limited fastboot and hardly any use at all , and will not allow you to unlock bootloader.

v1.2, but I just managed to get into fastbootd mode. It seems like there are no commands available though, just as you said. Is EDL worth anything? What would be the steps to flashing this phone if there is no support by OPPO?
