So when i try to fastboot the bootloader .img manually, it says:
sending bootloader ... okay
'writing bootlader'.... failed (remote: (invalid state))
so what do i need to do to fix that?

Is your bootloader locked?
Sent from my Nexus 7 using xda premium
it said lock status: unlock
So i would presume its unlocked...

OK. I've never seen that error before. And a quick google search doesn't come up with anything either.
You could try restarting the bootloader with
Code:
fastboot reboot-bootloader
and trying again.
The only thing I can think of is you could be trying to flash the wrong bootloader (which i doubt) Just to confirm you are trying to flash bootloader-grouper-3.34.img
Also, to just unroot you don't need to reflash the bootloader. Just boot.img and system.img

Yes, I am trying to flash bootloader.grouper-3.34.img
And Im flashing bootloader because its I'm told to do in this thread? http://forum.xda-developers.com/showthread.php?t=1781250
I will try what you told me and see if it will work
So i rebooted the bootloader, and it still gives me the same thing. Whats the command to boot.img and system .img?

Both the boot.img and the system.img are in the image-nakasi-jro03d.zip you must extract them first.
Then run: fastboot devices (to make sure you're connected) if it returns the serial number then proceed.
Code:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot erase cache
fastboot reboot
This should maintain your data and unroot your nexus.
However, I am a bit concerned about the invalid state error. I can't find anything about it at all. I'm worried your nand might be corrupted and proceeding with this might lead to an unrecoverable state. Maybe someone else can weigh in on this... I don't want to scare you but I don't want to be responsible if something goes wrong.
hmm... I hope more people would weigh in on this? Cuz im exchanging the nexus 7 due to flickering screens, and im new to the rooting/unrooting stuff so i dont want to brick this device cuz im a n00b.
hmm... I hope someone else weigh in on this to help, cuz I'm going to exchange this nexus 7 for another 1 because of flickering issues...
Restart, carefully check
My nexus had the ghosting issue and I had to unroot my device to ship back today. Heres how I did it.
1. Download stock ROM from Google.
2. Unzip stock ROM from Google. The unzipped file will have 4 files in it. (Boot loader grouper image, flash all.sh, flash base.sh and the image.zip)
3. Unlock your device by clicking the unlock button on nexus root toolkit
4. When your device wakes turns on set it back up. No need to log into Google.
5. turn a dB back on in development
6. Click flash stock + unroot
7. click other/browse
8. For choice click I did this already.
9. Click OK
10. browse to your unzipped file location with the 4 files in it.
11. click OK
12. Done

Did you find a way to flash the Bootloader?
I'm thinking about a hardware issue as well. Are there any Devices, with corrupted NAND's known?

i dont know what i did..i was trying to unlock the bootloader and root my n4 but it came to an end that the only way to boot into android is if i fastboot boot boot.img..if i reboot my n4 it will get stock in bootloop and one more thing..by accident i deleted mms.apk and now it is no where to be found..the only way is to flash the whole rom?
If all you did was fastboot oem unlock and fastboot boot boot.img, then all you should have to do is reboot the phone. It will take a minute to boot since you wiped your data when you unlocked the bootloader

Hi i want to downgrade my nexus 7 (wifi only) to the 4.2.2 firmware in order to unlock the device´s bootloader? Should I just flash the factory image for 4.2.2 or must I need to do it another way? For additional info do I have a (wifi only) Nexus 7 running stock 4.3.
Thanks!

Don't quite understand why you want to downgrade?
You can unlock bootloader from the present firmware too.
Just boot into boot loader (turn off tab and press the vol up , vol down and power button simeltaneously )
and type
Code:
fastboot oem unlock
in fastboot mode
And just pass the disclaimer in the bootloader menu and you will be good to go.
And if you want to flash the factory images. I think you need to unlock your bootloader anyway.
PS Unlocking your boot loader erases all the data on your tablet. So make sure you take a backup before you do anything.

Hi
Please help! I unlocked the bootloader by using
fastboot unlock oem
after that I forgot to reboot and installed
fastboot flash recovery twrp.name.file
now I'm stocked at bootup and twrp is asking for password.
How can I fix this?
Could I flash the stock boot.img again?
ROM is stock OTA 4.4.2.
I know about flashing a factory image. I would like to find a way to save my data first, if possible.
Many thanks for your help!!!!!!!

Wipe cache from twrp, this is happened to me too But for the password i don't know...maybe reflash twrp, boot.img is the kernel so in my opinion flashing it wouldn't help you
Did you flash straight from 4.2.2 to after installing twrp? I did the same thing. I had to flash back to stock 4.2.2, install twrp, connect the phone to my computer, choose accept at RSA message, and fastboot flash to 4.4.2.

I see plenty of guides on how to unlock the bootloader which as I understand voids the warranty. Is there any way to relock the bootloader if I need to? Maybe someone could link me to a guide?
I've had bad experiences with dodgy solder in 3 LG G4 handsets so I sort of see the value in a manufacturer's warranty these days.
In fastboot
"Fastboot oem relock YourCode"
Fastboot relock still show that the phone was unlocked before but to revert to original state you have to flash stock firmware using this guide https://forum.xda-developers.com/mate-9/how-to/guide-rebrand-chinese-al00-mate9-to-t3554656/page57
This will lock the bootloader without any trace
Many many thanks.

Is the adb relock bootloader "Code" command connected with a factory reset? Do I keep my data?
