Please help to get out of fastboot/Logo screen!!

I was on CM 11. I wanted to restart fresh to I flashed
to KF 8.4.6 which worked fine. I then (this starts the
trouble) tried to reset device (remove personal data) from within kindle screens
1) rebooted to red screen
2) finally got into fastboot
3) tried this:
fastboot -i 0x1949 flash bootloader kfhd8-u-boot-prod-8.1.4.bin
fastboot -i 0x1949 flash boot kfhd8-freedom-boot-8.4.3.img
fastboot -i 0x1949 flash recovery kfhd8-twrp-2.6.0.0-recovery.img
fastboot -i 0x1949 reboot
4) it reboots and stays at yellow kindle fire logo
5) then I tried just this but same result:
fastboot -i 0x1949 flash bootloader kfhd8-u-boot-prod-8.1.4.bin
Any Ideas?? Please? I am not upset that I cant use it...I'm upset that I cant fix it!

Fixed it
Used SRT tool and finally realised also had to flash boot.img and recovery.img

[Q] Kindle Fire HD 8.9 LTE - Return to Stock

I rooted my KFHD8.9 LTE and first installed CM10.2 and then CM11.0 using the following guides.

Worked great!! Thanks to all developers!!
I did not know the LTE option does not work with CM10/11. (The LTE versions available are unreliable, I tried them). I would like the tablet it back to Stock.
I made a TWRP backup of my original kindle stock. I have tried to restore that version in many ways with out any success. Most of the time the tablet boots back to TWRP recovery. I really don't know the reason.
I did make boot/recovery/system image back-ups as shown in the above guides. Can I issue the following commands in the fastboot mode to return the tablet to stock (ver 8.4.6)?
Is there any other steps I need to take to ensure proper return to stock? What about partition image? Do I have to restore it? I don't remember making a back-up of that.
fastboot -i 0x1949 flash bootloader kfhd8-u-boot-prod-8.1.4.bin
fastboot -i 0x1949 flash boot kfhd8-freedom-boot-8.4.6.img
fastboot -i 0x1949 flash recovery kfhd8-twrp-2.6.3.1-recovery.img
fastboot -i 0x1949 reboot
PLEASE HELP!!
I am a noob and mostly worried about loosing TRWP recovery and bricking the tablet.

If you came from cm 10.2 or higher then restoring a backup in twrp might not work, I don't know what version of twrp you have but I am not familiar if the older backups would wipe out selinux xattribs on the data partition when restoring, if you know how to push and pull over adb and backup the backups to your PC first you could attempt a internal storage wipe if you wanted and then push the backups back to the device. Technically you can restore your backups with the commands you mentioned (though those arent exactly the the right files to flash mentioned in thencommands)but here's the one problem with that method, if that boot.img is from before you flashed 2nd bootloader and such then you will lose twrp, think its the same with system. So if you restore stock images you will have to reinstall twrp + and bootloader. I think kindle fire first aid can restore it for you with stock rooted but I am unaware of the jemlte model used the same bootimg and exact same system image as a normal jem model, so not positive if kffa helps or not.

Thanks stunts513. I was using twrp 2.7.0.0, but even tried with 2.6.0.0. Deleted and formatted all internal storage, pushed backup using adb - still it does not work. I do not have any hope of restoring with twrp.
I copied the incorrect commands above. I meant these commands to restore.
fastboot -i 0x1949 flash boot boot.img
fastboot -i 0x1949 flash recovery recovery.img
fastboot -i 0x1949 flash system system.img
fastboot -i 0x1949 reboot
I will try these commands, if it does not work I will have to use first aid tool.

Back to stock!!!
Here is what I did...
1) Booted into TWRP recovery and wiped everything (cache, boot, system, internal storage). Also format internal storage (Need to type "yes" to confirm)
2) Booted into Bootloader/fastboot from TWRP. (I think I restored su, not sure though)
3) Connected to PC and issued following commands - in the exact same order.
fastboot -i 0x1949 flash boot boot.img
fastboot -i 0x1949 flash recovery recovery.img
fastboot -i 0x1949 flash system system.img
fastboot -i 0x1949 erase cache
fastboot -i 0x1949 erase userdata
fastboot -i 0x1949 flash boot boot.img
fastboot -i 0x1949 flash recovery recovery.img
fastboot -i 0x1949 reboot
erase user data took a long time (2300seconds or so). I flashed boot and recovery second time because I found 2 different set of instructions as when to erase cache and userdata.
KFHD booted couple of times.. Voila I am in stock (rooted with SU). I think I can unroot with KindleFireHD89Root.zip (see link below, step10, option x)

twrp not working after flashing it

hello everyone!
I wanted to root my phone but i couldn't manage even if the way should be quiet easy...
-bootloader already unlocked
-debug usb on
downloaded twrp 3.2.3-0 sagit
“fastboot devices”
“fastboot flash recovery recovery.img“
“fastboot reboot”.
i didn't get any errors...
if i try this command: "fastboot boot recovery.img " the phone restart and stay in loop mode...
volume(+) + power keep giving me the stock mi recovery :crying:
MIUI 10
i tried this procedure several times without any result...

Instead of fastboot reboot do fastboot boot recovery name.img and install something
Oreo tastes better with Mi6

worked with twrp 3-2-1-1, but works only if i lunch it via shell

Rooting Motorola G6 Play gone wrong

Hi everyone,
I bought a Motorola G6 play model XT1922-3 type 374B and wanted root acces on this device.
So I started by succesfully unlocking my bootloader using the following tutorial.
After this a started tried to root the device using this tutorial.
This tutorial doesn't link to boot images anymore so I was able to find the moto-g6-play-jeter-patched-twrp.img somewhere else.
I did the following things:
- reboot to bootloader [Succesfull]
- fastboot boot moto-g6-play-jeter-patched-twrp.img [Unsuccesfull]
The device did boot the twrp image but I was unable to interact with it in any way. I couldn't swipe or press buttons.
I made a short video to show this.
I wanted to retry the whole thing so I did reboot to bootloader but then I accidently entered the following command:
fastboot flash boot moto-g6-play-jeter-patched-twrp.img picture of command prompt
After this I wasn't able to normally boot my device. When I try to do so the screen goes black and says n/a in the left corner.
Please does anyone know how I could either be able to boot my normal stock rom again or to have a rooted rom?
Kind regards Sven Onderbeke

Hi Sven,
This isn't going to be the most advanced reply, as I'm not very experienced with this stuff either, but it seems you have accidentally flashed your twrp image to 'boot', wherever that is, which is why the phone isn't able to boot to system.
Can you still boot into bootloader and recovery (twrp)?
If so, then I'd suggest using fastboot to flash a sock or custom ROM. I'm not sure exactly which one though, you have basically the same model as me and that seems to use the JETER ROMS a list of which are over here (can't post links yet, so you will just have to search on mirrors . lolnet . com /firmware/moto/jeter/official/ or remove the spaces
I seem to have somehow lost the partitions on mine, but will start a new thread question about that.

Just flash a stock boot.img to boot. Then just flash TWRP to recovery. In TWRP, format data. Type yes. Then reboot recovery. Then Use TWRP to flash magisk. Done.

Hi again Sven,
I just wanted to let you know that I just downloaded the following RETAIL ROM
ALJETER_RETAIL_9.0_PPPS29.55-35-1_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
and used the following fastboot commands, one at a time.
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot flash dsp adspso.bin
fastboot flash boot boot.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash oem oem.img
fastboot flash vendor vendor.img
fastboot erase carrier
fastboot erase userdata
fastboot erase DDR
fastboot flash logo logo.bin
fastboot reboot
Which rebooted into bootloader so pressed "start" and all booted fine now. It looks like we have the same device, so hopefully that will work for you too.

Question Root OXYGEN OS 13 MT2111_11_F.11 ?

Is there any way we can root MT2111_11_F.11 because for me fastboot appears to be missing as when i try volume down and power it just keeps on restarting after a see the fastboot screen for 0.01secs.
I tried using adb reboot bootloader as well but didn't work.

You should use adb reboot fastboot instead. Note that this mode doesn't allow to unlock bootloader if it is locked. But if bootloader was unlocked earlier, you may use flash command to flash patched boot.img
Code:
fastboot flash boot boot.img

go to github magisk, get apk install it on your phone, download your Full OTA, extract it via payload.bin extractor and take out boot.img then patch boot.img using magisk and do fastboot flash boot magiskpatchedboot.img

Button combination = Fastboot Logo flashes for a split second, Phone instantly restarts to system, no access to bootloader therefore impossible to use flash commands
adb from system > reboot to bootloader = exact same as above.

Not bootloader, but userspace fastboot (fastbootd) mode. The command is
Code:
adb reboot fastboot
