I made a hard reset through the recovery, but after rebooting the image remained fixed on the logo, so I tried "asus flash tool" (fastboot mode), with the .zip present on the official site, but gave an extraction error, then I tried to use ADB & fastboot for flash manually (the bootloader is unlocked), but also gave me error saying it could not flash, so I looked at all the partitions there (image attached) and I reset almost all (in some I did not have permission), now I have a tablet that only has the fastboot mode (no image or logo) on which I can not flash anything (but vrl partition yes). Does anyone have an idea on how it can be done? Is there a way to solve the flash error? or an alternative to fastboot? If someone had my own model of tablet could send me the partition files?
ps: before I reset the partitions if I did "fastboot boot recovery.img" it worked, now I have the black screen.

Long story short I bricked my phone when trying to flash recovery using toolkit. Now my phone won't turn on and recovery is gone as well. Somehow my PC can recognize the phone in fastboot mode although there's nothing showing on the screen.
So I tried the method in this thread:
http://forum.xda-developers.com/oneplus-one/help/wrong-kernel-black-screen-fastboot-adb-t2835696
It shows I flashed everything and it shows green color in the tool but when I checked the partitions, boot.img, recovery.img, userdata.img, system.img, etc are still broken. At that time the bootloader was still unlocked.
Since my computer can still see the phone in fastboot so I tried to flash the original image in fastboot. Again everything went through with no error but the phone still wouldn't turn on and the partitions are still same broken/corrupted. However the bootloader became locked after this. So now I end up with no more solutions. Since bootloader says locked(although boot.img is actually corrupted) I can't flash or do anything in fastboot command.
So I guess I'm really SOL right now... My only hope right now is maybe there will be USB JTAG or Nand flasher but I don't know if anyone can repair that right now.
Any suggestions?
fastboot oem unlock
fastboot erase system
fastboot erase boot
fastboot erase userdata
fastboot erase recovery
Now use twrp or cwm or whatever
fastboot boot recovery nameofrecovery.img
If your phone boots to recovery you may consider running e2fsck against data and cache partitions through adb shell
Best of luck
Hi to XDA comunity
... and happy festive season
I tried to install a new ROM. So, I followed tutorials and I have a huge problem
I passed to unlock the tablet
But, when I tried to install the new Recovery, the installation failed and now, the tablet doesn't want to boot
When I boot normaly, in recovery mode or Fastboot mode, I get this message :
Code:
Bootloader Version JB-653b3d3 (Unlock Mode)
Entering boot menu mode
Booting failed
Bootloader VJB-653b3d3(UnlockMode): Starting Fastboot USB download protocol
When I send "Fastboot device", the device is shown
When I send "Fastboot flash recovery twrp-2.6.3.0_a700.img"
Code:
sending 'recovert' <5736 KB>...
But still indefinitely
So I stop and retry and I obtain
downloading 'boot.img'...
FAILED <commande write failed <Unknow error>>
finished. total time: 0.???s
i tried to erase recovery and retry.
Tried with several USB cables.
I don't know what to do...

Thanks for any help !

make sure you have the a700 and not the a701 or a510 etc etc....
also, you could try booting directly into fastboot:
1. power off
2. hold power and volume down, while you're doing that, constantly change the rotation switch from lock unlock lock unlock.... keep doing it for about 5 seconds
try flashing from here... it might give you the same result but worth a try.
other possible problems:
1. the recovery you downloaded is corrupt
2. the recovery you downloaded was not a working version
3. you might not have the right usb drivers installed
4. you might have used the wrong recovery commands
5. command (sometimes) needs to be Run as Administrator on Windows (right click)
6. you might have waited too long to reboot to recovery, or used the wrong method to do it
it might make it easier for you if you just rename recovery on computer to recovery.img (so you can just type fastboot flash recovery recovery.img)
also, I have uploaded a copy of the recovery I'm using (it's newer)
you can also try (while in fastboot)
Code:
fastboot boot twrp.img
(or any custom recovery)
It should boot without flashing, and from there you're will be able to flash firmware, ROM, etc...

it might be fine but personally I would not try that... recovery and boot are not to be confused and bootloaders are not to be messed with
Hi,
Device is: Asus Zenfone 2, Z008
At some point I managed to brick it. Restored it using xFstk and some fastboot magic.
Now, the big issue is, I cannot boot to recovery.
I can load bootloader (do fastboot commands), chose "Recovery", but it will just boot normal into the OS. Droid with hazard doesn't appear, just normal boot.
Tried (not all at once)
fastboot erase cache
fastboot format cache
installing twrp
flashing stock recovery.img
No joy.
What am I missing?

Hi !
A quick answer has been provided here https://forum.xda-developers.com/showpost.php?p=71063211&postcount=598
Try this command after placing this recovery img into the adb folder and boot into bootloader
fastboot devices
enter
(check if it is recognised) then
fastboot boot recovery.img
( where recovery.img should be the exact name of your recovery you want to boot into)
Keep an eye on that thread you already have posted , more users may have replied
Good luck !
Hi all -
I have committed a stupid typo that has locked up my device: I just unlocked my bootloader and everything was working fine. I wanted to change the boot image so I don't get the "Bad Key" message at the bottom of the initial boot screen.
Unfortunately, in fastboot mode I typed:
Code:
fastboot flash boot logo.bin
instead of
Code:
fastboot flash logo_a logo.bin
Now a normal system boot fails and the device goes into fastboot with the message "Invalid boot image size! failed to validate boot image"
I am able to boot to TWRP by issuing the command
Code:
fastboot boot twrp-3.5.0_9-0-river.img
but I have no idea what to do after that.
How do I fix this?
After finding this thread:
Back to Stock & ReLock Boot Loader (Google Fi)
I wound up getting the $150 deal from google for the G7, had massive issues with the phone, so back to google with it. If you are curious the issues I had included: Speaker would randomly stop working, seriously I'd reboot, it would work, the...

I have a possible path forward.
I am downloading the XT1962-1_RIVER_RETUS_9.0_PPO29.114-16_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip file (it's huge).
Then I will then extract the boot.img file and do a
Code:
fastboot flash boot boot.img
and see what happens.
Edit: I will wait a while first and see if any gurus have some better advice
I ended up just doing a factory reset from fastboot.
Merry Christmas guys,
I have a really unusual situation.
First time that I have tried all tricks I know and I can't get myself out of this difficult situation.
I was trying to update Magisk with a patched boot file and after a reboot I was not being able anymore to access the system but only this black screen with the Crashdump Mode is appearing.
I can access the Fastboot screen, but no way to reboot to the TWRP recovery or to flash another boot.img, even through some pc flashing utilities.
Is there anything to try through another slot or something else?
I also tried:
fastboot flash boot_a boot.img
and I get this error:
FAILED (remote: Flashing is not allowed for Critical Partitions)
But my bootloader is unlocked and other commands like fastboot reboot works normally.
After I flashed through fastboot the images of boot, abl, dtbo, fw I can only access the TWRP recovery where everything is decrypted.
Any other ideas?
Try booting temporary into TWRP by using this command
fastboot boot twrp.img
If you can't use MSMDownloadTool
