Partition table doesn't exist -> bootloop fastboot

Frat

Hello,
I own a fairphone 3 that was running under e/OS. In order to install unbuntu touch, i first installed linéage 19.1 (android 12)
Everything worked fine. Then i used ubport-installer to install unbuntu touch. The installation went smoolthy until the "update" phase.
Since my phone is always starting in fastboot mode, if I select "recovery" (in red) it restarts in fastboot !
I tried to reinstall line 19.1 by first flashing the image:

fastboot flash boot lineage.img
Answers :
Sending 'boot' (65536 KB) OK [ 2.438s]
Writing 'boot' FAILED (remote: 'partition table doesn’t exist')
fastboot: error: Command failed
I tried to flash the twrp image to fairephone 3 using the function:
fastboot flash recovery twrp.img and I get the message
"FAILED (remote: 'partition table doesn’t exist')"
I tried to reinstall line 19.1 by first flashing the image:

fastboot flash boot lineage.img
Answers :
Sending 'boot' (65536 KB) OK [ 2.438s]
Writing 'boot' FAILED (remote: 'partition table doesn’t exist')
fastboot: error: Command failed
I also tried fastboot recovery and phone restarts in fastboot mode

I found on XDA forum : "sudo fastboot flash boot boot.img" but it doesn’t work either.

Finally, I tried to reinstall ubuntu touch with the ubports-installer but it blocks from the beginning.

Can someone help me to solve the problem?

Thank you in advance

@frat Run TWRP from your PC make sure TWRP is in your fastboot folder:

./fastboot boot twrp.img

From there you can wipe the partitions and start again.

If it fails, I don't know if the Fairphone 3 is a slotted device, i.e. has slot A or slot B. It may not flash TWRP as there is no active slot i.e. not bootable).

If it is a slotted device in Fastboot run the command:

fastboot getvar current-slot

and then set the active slot, i.e.

fastboot --set-active=<slot>

Thank you for your answers !
fastboot boot tpwr -> FAILED (remote: 'unknown reason')
fastboot getvar current-slot -> current-slot: INVALID

i used " fastboot --set-active=a " and i have ->
Setting current slot to 'a'

so i tried to flash an other time the twrp :
"fastboot flash boot twrp.img"
Sending 'boot' (31512 KB) OKAY [ 0.823s]
Writing 'boot' OKAY [ 0.166s]
Finished. Total time: 1.030s

but the phone still restart into fastboot mode impossible to have recovery

@frat try :

./fastboot boot twrp.img

again and see if you can get into TWRP.

@joaopedro020 This is an English language forum so I have (using an online translator) translated your post:

Good night troop. I was having the same problem, so I did a method that helped me a lot and was able to reinstall the older stock rom with biometrics.
This is the method with all the commands to do the reinstallation

Your link unfortunately doesn't allow me access.

I think you should first try rebooting into the bootloader/fastboot mode and check if your device is recognized by your computer using the command 'fastboot devices'. If it's recognized, you can try flashing a stock ROM or LineageOS using the appropriate commands.

If the partition table issue persists, you may need to use tools like fastbootd or QFIL to rewrite the partition table, but this process can be complex and may require advanced technical knowledge.
