Hello.
please help me..
boot menu Fastboot AC :/
Every time when i connect my phone to pc with fastboot it says "FASTBOOT AC" . I tried with other cables and other pc always "FASTBOOT AC". I don't know how to fix this so i write there. Can you help me?
Lots of results if you Google 'fastboot ac'. Is your device recognized? Are you using USB3?
Maybe a solution in this forum
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?

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.
Here is my Problem.
Adb works without any Problems.
Command just doesnt detect the fastboot mode.
So, when i start the fastboot mode, odin detects my phone and Im able to flash.
Just when i want to use commands like
fastboot devices
fastboot erase system
etc
it says nothing, or waiting for device.
I opened up the Devicemanger. The usb driver is called "SAMSUNG Mobile USB CDC Composite Device"
Its working fine, but i just cant acess my phone with cmd.
I just need that to do a clean full wipe.
this is driving me nuts
fastboot erase system/boot/preinstall etc
Thanks 4 your help and sorry for my bad english xD

Samsung devices do not support fastboot mode, only what they call "Download mode". This mode can be controlled by Odin only, so fastboot tool does not work.
Hey guys, I just got LG l9 from my friend but it is (I am afraid, not knowing much about mobiles) bricked.
When I turn it on it says:
-------------------------------------
Secure booting unsuccessful!
Cause:
-------------------------------------
and after that it turns off. If I charge it it turns on and shows battery charging. At combination of Volume+, power button it goes in Recovery mode.
It shows "This mode is for data backup service center. After removing and reattaching battery, press power key to reboot and keep using phone" and from there I can't do anything, just able to take out battery.
If I try combination of Volume-, power button it shows little android and loading bar, after few sec it restarts and shows booting unsuccessful.
I am not sure what he did with it, but pretty sure he rooted it. Is it possible to fix it, hope someone will provide me some help
Thanks !
It is possible to fix, you need to unbrick it. Find the stock rom for your device and find a good tutorial on how to flash em. Good luck!
Thanks for the reply ! I found everything I need, but I got problem - cant enter download mode. On combination of Volume+ and plugging cable I get S/W Upgrade, and on combination Volume+&- and plugging cable I get nothing. Any ideas how to get in that download mode? Thanks!

Try that, then in adb, type adb devices and see if your pops up, if not, try fastboot devices. If it popped up in adb, you can sideload the zip file, if on fastboot, you can flash it.

Thanks for your patience and answers! Problem is I cant reach emergency-mode. I always get S/W Update. Under adb devices I can see my phone in recovery mode (was thinking maybe emergency=recovery mode). I tried sideload, it starts loading but after some time I get error:closed. I tried doing adb usb before as well but gave no results.: . Any other ideas? Is there any way to "make" phone run ROM from SD card (in recovery mode can't navigate anywhere like I can on my other phone).
Again thanks for your help and time!

If it sees your phone as recovery, you can be rescued! Run adb shell and once the shell has popped up, type ls and if you see the phone structure of directories, you can exit the shell and push the file from your pc to your phone. But before you push, I want you to try to run adb reboot-bootloader and see if fastboot recognises it.

I think I am making some progress. First on adb reboot-bootloader my phone reboots into secure booting unsuccessful, same as before. On the adb shell/ls I get to see cache, charger, data, default.prop, dev, etc, system, temp and lots of other things. I guess that are directories we are looking for. But when I go adb push filename.zip /data/media I get failed to copy filename.zip: Permission denied. Guess nothing can work at first, sorry

This gets complicated, I found xloader and uboot, but problem occurs when I try to install fastboot drivers, says third party doesn't contain digital signature information?? I think I was close with shell from adb, just how to get privilege to push files? Tried so many methods.. Thanks again on help.
Hello!
I cant get further on with an my tablet an RK3168 device.All the specs are in this topic, because i was looking for a rom:
http://www.arctablet.com/blog/forum...ssible-clean-4-2-2-or-a-customcwm-rom/#p60994
But i ran into things what i can not really understand or place, and i also already tried a lot already..Maybe its the soc itself, hope someone can help me a little bit.
I wane install a rom, so i first made an backup with RK1.2tools and this backup is ready in flashtools1.37 from finless.It finds rk loader and its ready to flash..
But here i get stucked, adb works, minimal adb &fastboot , google usb driver, with usb debugging on..Adb works, but for example fastboot reboot-bootloader..Only switches off the device, it doesn't boot up in any mode...Tried button combinations but only recovery can show up.So no commands work for fastboot plus starting fastboot with keys, looks impossible.Also in recovery there is no fastboot.In adb i can see all the commands, but everything what starts with fastboot, will give me only an waiting for device output..Also adb shell gives me root, rooted with kingroot..But same thing, goes off and no fastboot..And yes adb has permissions from kingroot.
Because adb works, i can not believe that fastboot would not work, i think myself its the tablet who first has to boot into it before a driver will work.But fastboot oem unlock or fastboot flashing unlock bootloader all are not working.But why it even doesn't start in any fastboot from command pff i cant understand that..
On the internet i see that even fastboot has an screen..Could it be locked or so?
Only weird thing besides that is this! If i put it off, plug in usb cable and charger!!Press vol up or power, battery shows up loading..And i see rockusb device in device manager win7.I can install adb or fastboot on top off rockusb device.But adb shows no server running.And adb devices gives this: 1234567890ABCDEF Device....Thinks its no fastboot but very weird.It only works this way when charger is inserted and battery is loading..
Besides that, rooting was also a pain ...Tried rk188 solution for rk3168, but double zero after 3 times booting..Looks rooted, but Su is not there and cant get installed.It always ends like that, with or without kingroot.And other ways the same, with emulator pushing su and removing kingroot..Doesn't allow Su to be installed properly.
Nothing looks logical for me at the moment. No fastboot, but seems flash ready in RK1.37 tools.Is there a way around fastboot to find out first if my loader is unlocked.
I don't wane brick it with an locked loader, so how to get further on from here or are these soc different from others?
Thanks for any help!:good:
