you need to reinstall your adb. your commands will start working.
if you are using windows then go device manager and uninstall adb driver, then click search and it will reinstall the adb. after that try again the commands. thats what i do always when i stuck in that situation like yours.
or simply try another computer for adb

I tried to root my device after rooting it went into a boot loop then I flashed it with it custom rom using twrp it still didn't work out. Later I used clear data option in twrp and deleted everything including the rom....Now the message"No rom found " was shown in the recovery....So I tried to replace twrp with normal Huawei recovery, so I used the Huawei extractor tool to extract the recovery file and flash it...mistakenly I flashed Erecovery...now I am stuck with it.. I don't even enter fast-boot mode no even into the normal recovery and is not recognizable by pc
Now, the only way out is to flash stock rom using force update method (by pressing both volume buttons and power button simultaneously)
my phone details: https://ibb.co/kOzQCF
What command did you use to flash the ERecovery?
http://download-c.huawei.com/download/downloadCenter?downloadId=80950&version=321934&siteCode=lt
This is the EU ROM B340 for the L01
Also did you try reinstalling fastboot drivers?
Good luck!
Also next time when you encounter no OS please just move the zip file using the mount function
Or using a SD card

And flash them with these commands:

fastboot flash system SYSTEM.IMG
fastboot flash cust CUST.IMG
Then reboot: fastboot reboot

Did you unlocked your bootloader and after that did you flash TWRP without reboot?
Maybe I'm wrong but when you unlock your bootloader, the phone automatically reboots into stock recovery and and immediately wipe everything (included your internal storage) and then reboots normally. If you flashed TWRP after unlocking your bootloader, your phone will boot into TWRP but it won't wipe anything.
I think that happened.

Mmh after I unlocked the bootloader, my phone was freeze on this
Select Boot Mode :
[VOLUME_UP to select. VOLUME DOWN is OK]
[Recovery Mode]
[Fastboot Mode] <<==
[Normal Mode]
=> FASTBOOT mode.....
So, I forced it to reboot, after everything seems ok.
What part must I reflash ?

When I unlocked the bootloader my phone freezed too, so I typed in Windows cmd "fastboot reboot". After that, my phone was formatted by stock recovery.
You should reflash stock recovery if you have TWRP, so the stock recovery can format your internal storage, if not, your phone won't boot.

Ok, so fastboot didn't work at all (just waiting devices)
I tried to reflash TWRP nothing happens, I tried to do a factory wipe with twrp but nothing happens too.
I searched a stock recovery for nokia 3 1032- Android 7.0 but found nothing - must i use stock recovery for Android 7.1.1 or do you have a link to a stock recovery for 7.0 ?
------------
I found this on XDA : Is it a good way if nothing work ?
Hi, I was able to unbricked my phone using this:
"https://mega.nz/#F!0lMBiIIYgB!c9TeOWFrKpf0XfOwXzunrg"
Here is the SP Flash tool, the download agent for Nokia's phones and the ROM unpacked
As SkaboXD said (i don't know if it were in this post or in other one) you must:
1- Download the files I provided you
2- Install SP Flash Tool
3- Choose the download agent
4- Choose the scatter
5- Press download and plug your phone (it must be OFF)
6- Wait and enjoy.
I must thank to everyone who give us this files. I couldn't unbricked my phone without your help

You can flash again with OST LA. Or try to flash with SP flash tool the whole rom or just the recovery. To flash with SP flash tools you need a nb0 unpacker tool (my previous post have a link to another post with the tool link).
BTW feel free to ask something that you don't understand. :highfive:

Is like unlock bootloader, just change "fastboot oem unlock" to "fastboot oem lock".
But your internal storage will be formatted again by stock recovery, so you must have stock recovery installed.
After relock, your device will get ota updates, so you need stock recovery to install them.
I recommend root your device after all the updates, even you can install TWRP without problems.
I installed TWRP, root and installed stock recovery to get updates. Choose the method that you like.
Good luck. :highfive:

No don't, just grab the stock boot img and flash in fastboot. It will get you out of that. Don't reflash twrp. Not supported yet on A11
