Long story short: installed custom rom, went into TWRP bootloop, tried to flash back to stock ended with bootloop.
Is there a way to enter into fastboot? So I can at least flash TWRP back.
Currently it's booting, displaying the boot screen with the orange state warning and almost immediately rebooting
Fastboot on Android side gets activated by bootloader. Hence you should be able to run Fastboot commands.
To test this you run on Windows computer
Code:
fastboot devices

Tried to spam sudo fastboot devices on linux, but to no avail.
Trying on windows as soon as I find the drivers
Installed the drivers from here and rebooted: https://gsmmobiledriver.com/umidigi-f1
Spammed fastboot.exe devices in admin power shell, but again no output at all
While it doesn't respond to fastboot, I noticed that, while booting, lsusb displays the preloader:
Bus 003 Device 010: ID 0e8d:2000 MediaTek Inc. MT65xx Preloader
Is there a way to interact with it?
It seems it's possible to unbrick the phone with SP Flash Tool, I can't find a guide or how to do it however...
Edit: all guides I had foudn require to device to be powered off. Given that my case is a bootloop, I will try to wait until the battery has dried up
Ended up following this: https://forum.xda-developers.com/t/stuck-in-a-boot-loop-and-cant-access-recovery-mode.3818742/
Standard procedure with SPFlashTool: no preloader, download all else. Results in a "PMT changed for the rom; it must be downloaded", so I probably have a faulty firmware copy
Edit: wrong firmware, my phone uses the global instead of the EU one for some reason

Hello everyone, I'm using Redmi Note 3 and I have tried rooting it several times.
I have unlocked the bootloader. I have also installed the adb drivers.
When I connect phone in fastboot mode and write 'fastboot devices' in cmd it doesn't return anything. But when I connect when its on, adb devices returns the device code.
Please help.
Same, happens to mine too. Used to work with a previous install of windows, but now, nope.
Had this issue too.
Try going to Device Manager and check to see if Kedacom USB Device shows up. Under which, Android Bootloader Interface should be present. Install minimalist ADB and fastboot and right click Android Bootloader Interface. Click Update Driver Software, browse computer, and then click the option to list driver files already present on your drive. It should pull up a fastboot driver that's an older version than the one you currently have. Install that and fastboot will work again.
Doesn't work
Can you please link the files for download when we're updating the driver software.
I ported TWRP using Android kitchen to flash to my device (Coolpad 801es) since there isn't an official version. For some reason, I can't seem to get fastboot to play nice with my phone (see my earlier post) so I used flashify. On reboot i'm stuck in a bootloop. I did have the foresight to back up my stock recovery with flashify and transfer it to my PC first, in case something went wrong. Now, I can't boot into recovery at all and ADB isn't working since the phone isn't being recognized by my PC when I plug it in. I just want to flash the stock recovery back and fix this. I can get into fastboot, and the PC does recognize the phone in fastboot, but when I try any commands it just hangs at waiting for device. I've googled but every solution i've seen for fixing a bootloop tells you to boot into recovery to do so.
Can someone please help me out?
UPDATE:
Upon further research, I discovered the reason fastboot commands weren't working is because my phone apparently isn't whitelisted in the fastboot exe. However, if I type Fastboot followed by -i 0x1ebf the commands seem to work. Using this method, fastboot devices lists my phone and fastboot reboot reboots the phone.
I think i'm on the right track, but when I try "Fastboot -i 0x1ebf flash recovery (path to recovery.img)" the terminal shows "sending 'recovery' (10240kb)..." and nothing else. No progress indicator, and i've waited 10 minutes for it to complete which should be more than enough time to flash a 10 meg file, but there's no change it just sits there. Like I said, I think i'm on the right track but I could REALLY use some help. I can't be the first person on here with this problem. Can someone, anyone, PLEASE help me.
So, more Googling would indicate that either i'm not using the correct USB port, or that my bootloader is locked. I have tried all the USB ports on my PC (front and back) as well as two different cables, no joy. As far as the bootloader being locked, the phone is rooted which I thought meant that the bootloader is unlocked as that is part of the rooting process. I try "Fastboot oem unlock" to check but I just get "failed remote no such command unlock" and there is no OEM option under developer options on this phone. I'm trying to piece this together but I could really use some 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:

Hey guys - while trying to unlock the bootloader on my HDX 7, I flashed the older aboot per instructions and now cant get the HDX to boot. It shows a backlit black screen when attempting to boot, IT IS recognized by the computer, and I have ADB composite drivers installed, so thats what it is seen as in device manager. I can't see the system mounted as a file folder, however, I can get it to semi-respond to fastboot commands. fastboot devices lists the serial number, fastboot reboot will reboot it back to the backlit screen, fastboot -w did its thing and wiped it, fastboot flash boot boot.img seems to flash the boot.img, but it still will not boot. Also, NO adb commands are working, and it is not seen when adb shell or adb devices is executed. Am I totally F*cked, or is there hope that I can somehow flash a recovery via fastboot and get a system img flashed? any help or thoughts would be great.

Barring a hardware problem your device is likely recoverable. Sounds like you may have flashed the wrong aboot; verify you're using the appropriate image. Aboot-13 is for the 7" (Thor); aboot-14 for the 8.9" (Apollo).
If that's not the issue you will need to coax the device into 'bulk mode' and rebuild from there. Not hugely difficult if comfortable with Android devices and working at the command prompt. There are random posts describing the process in the unlock thread. I'm not in a position to post links ATM so you'll have to do some digging. Read carefully; details and sequence of operations matter.

I flashed aboot 13, but the device never booted after I flashed that and twrp. I figured I could get into twrp since I had flashed it one step previous, but I cant. So i wiped it using fastboot -w thinking I could get rid of the aboot file, then flashed twrp again using fastboot flash recovery recovery.img, it ran through its thing and seemed to flash successfully, but I still cant boot to anything but a blank black screen. no logos or anything. It does respond to all the fastboot commands, of which I only know enough to be dangerous. I've tried changing the drivers around to get adb working to no avail. It seems to be stuck in fastboot mode, even when i fastboot reboot and quickly unplug it. Just not sure where to go from here - it had 4.5.5.2 on it before all of this.

Ok, I executed fastboot -i 0x1949 erase aboot and seemingly put the HDX into bulk mode - I can now see a bunch of disk drives on the computer, and it is now recognized as "other devices" "QHSUSB_BULK" in device manager. I still am unable to execute adb commands at this time.

ok sick, I was able to execute those commands for aboot and twrp 3.1.1.1 and get the HDX booted into TWRP. now my issue is that I have nothing to install to get a system image going. Any suggestions on something safe?
Got slimrom installed and running 7.1.2 - awesome! Thanks so much for the help!
Hi all,
Just bought yesterday this phone and after doing typical actions like android config (oem, debugging, etc.), installed adb and fastboot. PC recognized command adb devices and shows the phone but when I reboot to fastboot mode, it stucks and the device manager shows unknown android.
Have read all the tips here, forums, youtube, etc. but no way. Tried in 2 different computer with same results. Installed last android studio with sdk manager, same error. Installed oneplus drivers and also the same.
Even I have tried a different cable but no success at all.
This is so frustrating situation, ever more considering that I'm not newbie at this (years ago always changed rom every month and smartphone every 2 months).
Any advice? Format pc? Install other windows in other partition?
Or selling the phone and buying another brand

Did you select always allow from this computer after enabling debugging and plugging your phone into computer when phone was booted and running(not in recovery or fastboot. Also adb does not work in the bootloader only fastboot commands. Secondly search for the insecure modded stock recovery if you want to do adb access commands in recovery. There is also a fastboot d mode on our phones which look like recovery but you can flash all partions via full fastboot to get to fastboot d your phone has to be on then you type adb reboot fastboot
