I use flashfire to flash OTA but fails. Now I cannot boot system and recovery. At the same time, I didn't enable OEM unlocking, so cannot flash stock image.
What should I do?
@xunholyx
Try to RMA

Sorry to hear that. Don't know if this will help, but it's worth a shot. If you RMA it, you are essentially telling Google that you messed up, but want them to replace it because of user error. Don't know if they'll go for that. Like the ol saying goes...you break it, you buy it

Even if pay for fix, it is acceptable. It is a fact that I do wrong thing, and I am willing to pay for it.
But if can find a easy way except RMA is better.
Overall, please some advice about how to solve this. Thanks.
Does anyone know if qualcomm flash can flash image without oem unlocking?

Flashfire is a root app. It will not run without root. I think maybe you've left out a few details. Have you attempted to fastboot boot TWRP? I don't know if it will work but it's worth a try. Without access to Recovery, you can't even sideload a rescue OTA.

I must have forgot some what I did.
At first, I can boot twrp, but I do wipe then change slot in it. So now I am in slot which has no system and recovery, and cannot change slot in fastboot too. So I cannot do sideload.
I just don't know I can do sideload to fix when bootloader locked. And after I know it, I cannot boot recovery.?

I asked if you have tried to fastboot BOOT twrp, not flash it. Put twrp.img in your ADB folder and "fastboot boot twrp.img". BTW if you have recovery, you can sideload an OTA. You can't flash a full image, but you can sideload a full OTA.
Edit: I suggest you study the new fastboot commands. It is possible to set A or B active.

Sounds about right fasboot twrp . That has saved many phones.
If you can't figure out what to do pay a Dev to use TeamViewer to help you out.
I did that 5 years ago until I understood
ADB commands

boot, set active, flash, flashing of fastboot all don't work, because bootloader is locked.
Just reread your post. You can save you phone. You need latest platform tools from Google. Then 8.1 ota image from Google. Learn fastboot commands.
When people start to jump ahead and push,click,touch things they shouldn't you end up here.
Fyi all files for easy reference should be in the plat-forms tools folder.
Download them now.
So let's start:
Fastboot --set-active=_a will set to "a" partition, usually not bootable
Fastboot --set-active=_b will set to "b" partition, usually bootable
Try this:
Boot boatloader (pwr button and volume down same time from phone off state)
Fastboot --set-active=_a
On phone scroll to recovery factory reset
Then
Boot boatloader (pwr button and volume down same time from phone off state)
Fastboot --set-active=_b
On phone scroll to recovery factory reset
If USB debugging wasn't turned on, boot to recovery and and side load 8.1 ota.
Follow instructions in recovery side load menu
I think it's "adb sideload filename.ota.zip"
Factory reset after boot
Or just get platform tools and 8.0/8.1 imagine depends on what you are on and restore. Probably won't work since OEM/debugging not switched on.
If you get it up and running unlock the phone to help you in the future. Yes both OEM and critical.
Good luck

Which phone? Unlocked version or Verizon version
Which platform tools
Windows, mac, or Linux
What does the bootloader screen say?
Fastboot devices what does it say??
There is a lot of possibilities. Messing with partions usually causes errors. Though from reading sounds like ot can be fixed.

I'm on same boat with him.. Unlocked version, latest platform tools, Windows 10, Bootloader says "Locked", fastboot devices show serial no. and good works.. But fixing is not possible... Locked bootloader and not accessible recovery... All known fastboot commands return with "........ not allowed in Lock State".. RMA seems one way for us..

The only thing that matters is that the bootloader is locked (no fastboot is possible) and no recovery mode (no adb is possible). Done. OP is from China where there is no RMA, so he is "extra" S.O.L. I recognize you are wanting to help, but those are the facts.
I understand he is more then likely SOL but I have time and want to try to help. Xmas miracle!!!! lol
what happens when you start the phone what does it say?

If your locked how did you boot TWRP?
what did you wipe in TWRP?
Can you get to it again and select slot B?
Wait until just after Christmas, then contact Google and say you got it as a present and it says no operating system when it turns on. They're RMA it.

Does this mean if you have this IMG, you can flash after any other (even older) IMGs without verify check?
With fastboot and OST LA from here?
That would be a fantastic news!!! :good:
Overall, the fastboot doesn't seem to work on my device. Once I get my phone into bootloader state it says naturally DOWNLOAD MODE but any fastboot devices command ends up with <Waiting for devices>. I've switched drivers from Nokia's one to diffrent non device specific but nothing helps. Any idea on how to fix it ?
- edit -
Came out that the adb and fastboot drivers can't be outdated so be sure to use newest from SDK Platform Tools - otherwise u won't see the device.

Didn't checked by flashing it. But, logically yes. Though system partition is still encrypted. That may cause an issue. But for custom ROM developers - it can be a start. Provided - your bootloader is unlocked.

Fastboot need Admin permissions on windows open a CMD as Admininstator.
On Linux just login into user root.

I have it problem on Windows 10 too. If you want very strong, download any Linux-based LiveCD, flash it on USB and load. After this install adb and fastboot from LineageOS site (delete space after "https://" https:// wiki.lineageos.org/devices/bacon/build) and run commands.
P.S.: I am sorry for my bad English, but I hope help you
Wow, you are a genius! So glad to see twrp on our Nokia 8 xD but with encrypted /system. Does it mean nandroid backup is not possible at the moment? Also, with your magisk patched kernel, can i flash over or do i need to first flash twrp then reroot with your method?

Flash TWRP img, then re-root using Magisk method provided in the URL.
Created another version of TWRP. Now /data is browsable, but showing garbled file names So, nanodroid is still unachievable. Don't have a backup phone, so could not take the risk of loosing my data, else could have un-encrypt ICE filesystem encryption and could have build a stock based ROM without encrypted partition.

Thanks bro. You are making tremindous progress on this phone though. Hopefully you inspire other devs to jump the train on our N8
Does this work with a locked bootloader? And if so do I just follow the steps here? Or do I need OST LA?
thank you so much for your time and effort. Much appreciated. Can the stock recovery be backed up and restored Later? Is it advised to flash it on TA 1012 Nokia 8 unlocked? How can we revert to the original state? Does OEM Unlock help in this case? Is it an image of the whole OS like previous mod attempts?

You need an unlocked bootloader. Else fastboot not let you overwrite /boot partition. No OST LA required.

There is no different partition for recovery. So, just flashing the original boot partition ( boot.img ) will be enough to restore. OEM unlocked is required to decrypt the /data partition. This one is just the boot.img modification.

It is the same image for TA 1004 / TA-1012 . Taken from v4.88B update.
I realized that after the download finished. I apologize for jumping the gun. Since I'll have to unlock my bootloader, is there a way to do a full system backup through adb or otherwise? Most likely, I have a locked bootloader and before I can figure out a way to unlock it, I will have to backup as much data as possible since unlocking it will most likely wipe all my data and do a factory reset.
You can not make a backup unfortunately.
could you and other people making useless threads put it in the thread title and OP so that 99.9% of nokia 8 owners that dont have a way of unlocking the bootloader dont waste our time by having the salt rubbed in, thanks
Without fail, when running the latest twrp, I get an error when flashing different rom zips. It's always the same error during step 1 and sometimes during step 2. I am on slot A when flashing the room, by the way.
The error just says it can't flash, there is no error code or description or anything like that.
When I was able to flash a rom, I tried to reboot into B for the vendor image, but none of my files were viewable, only folders with numbers and letters.
I'm confused, and I'm not a noob. I came from the regular Pixel and I was able to flash no problem.

Is this when you fastboot into twrp, or do you have twrp already installed? Have you tried disabling screen lock before you enter twrp? And I assume you've run both bootloader unlocking commands as well?
This is when using skipsoft.
Do I need to run the critical flashing command manually or something? The reason I ask is because I'm not sure skipsoft does that.
I'd love to be able to flash alll this stuff without even using twrp but I'm not sure that's possible.
So I boot twrp, wipe and flash the ROM. But it fails right there. Is there a step I'm missing?
I do know how to flash individual images thru fastboot by the way, like when going to stock. Here is where I did do the critical flash command.
No I haven't tried to disable screen lock.

Typically you need to have fully unlocked the bootloader with these 2 commands...
fastboot flashing unlock
and.....
fastboot flashing unlock_critical
Especially the critical, or else you won't be able to flash any roms. I don't know if skipsoft will do this. I know the Deuces scrip will. To find out what is/isn't unlocked run.....fastboot getvar all....
Then you'll know. If you have to unlock critical, which I think you will, it'll wipe your phone completely. So backup your files and such before you do :good:
Any manual methods that work? I mean to flash the roms.

I believe there is, but I can't find what it is. I think it's adb push (name of file) or adb sideload through twrp, butI could be wrong. Either way, you first need to be sure your fully bootloader unlocked before you can flash anything.

Ok I almost forgot.
When I first unlocked the phone I was able to flash Nitrogen, both the ROM and twrp. But when I rebooted recovery to get to slot B, all I saw were various numbered and lettered folders. Looked like registry folders for Windows.

Well that changes things a little. You at least have unlocked one partition then. And you can update factory images via fastboot? If so, then your fully unlocked. So you've got a twrp decryption error on slot B. You may want to disable screen lock security, and try again. You could also try fastbooting into twrp as well with screen lock also disabled.
Thanks. I'll try that out later.
But after I was unable to get into Nitrogen, I flashed stock manually and tried it all over. From this point I kept getting error after error in twrp.
After the errors, I got the Device is Corrupt screen, and freezing on the Google splash. From there I'd have to again start all over.

Also, you might want to try fastbooting the factory image with the -w removed from the flash-all.bat file to slot B. Then fastboot into twrp and try again. You will not lose any data by doing this.

Jesus christ. I'm in a cmd window right now, with the latest platform tools installed.
I ran the command just as you typed, (I'm in bootloader, bootloader version tmz20j by the way). Also, my bootloader version has changed a couple of times during all of this. It was tmz20bb, then tmz12g when I flashed the latest June image...now it's this 20j version.
Anyway, this is what I'm typing and this is what I get in return:
fastboot --set-active=b
fastboot: error: Device does not support slots
I'm at a real loss, obviously this damn device supports slots.
EDIT: OK hold on, when I flashed the June image bootloader version, ran the slot command in ADB, I was able to navigate to the right slot.

Fwiw, after you flash a rom and twrp, if it doesn't boot up, go back to twrp and flash the rom and twrp again. Flashing roms or taking OTA's automatically switches slots on you. Always best to keep screen lock disabled until you are done.

FAILED (Do not allow to flash Bootloader image on Unlock device) & TWRP - Failed to mount '/firmware' (invalid argument)
I'm using the Lenovo p2a42 32gb 3gb version (India)
My phone is stuck in fastboot mode. Bootloader is unlocked.
I have the latest twrp - 3.2.2.0 as recovery.
I flashed everything except the modem and bootloader to stock.
Bootloader & modem wont flash - cannot flash unlocked bootloader error.
I have tried everything I can think of:
1. Restore to stock 7.1 (cannot flash bootloader error)
2. Relock Bootloader (not allowed error)
3. Even gave my phone to a repair guy as last resort.
No luck yet.
Its 17000 bucks worth.
And has been laid to waste due to my ****up.
I really want to repair it myself if possible.
Please help me if you can. I'm open to any and all ideas.
Thanks in advance.
Alright mate,
Download this HERE
Extract it.
Boot phone into bootloader/fastboot mode.
Connect it via cable.
Run flashall - stock reco.bat and wait until it is done. Your phone will reboot on its own.
Gimme some details if it doesn't work. Don't worry, it'll be fine.#
Also: NEVER RELOCK THE BOOTLOADER VIA COMMAND, that is a sure-way to **** it up much more.

Seems like you have a faulty battery or something on your hardware side.
Fun fact: getting into recovery(twrp) is done via Fastboot since the button combo is a ***** and isn't reliable. The timing is too stupid done.
The one team rescue files always work as long as you're in Fastboot/bootloader mode.
It's worth the try
I can't thank you enough @sm00th4f3
You are my saviour. It worked perfectly & my phone is working now.
Thank you sooooo much & keep up the good work.

Glad it worked
I restored the stock firmware.
My phone boots to the start screen , after I select the language it's unable to detect or connect to the wifi or to the mobile network.
Therfore I cannot proceed to finish the setup.
TWRP shows a firmware error-
- failed to mount '/firmware' (invalid argument)
Please advice @sm00th4f3

You shouldn't restore stock firmware from backup.
After using rescue tool.
Setup your phone from zero.
Or skip through setup.
Reboot to bootloader.
Flash latest twrp 3.2.3 can be found on official website
Change data system format to ext4 if it's not already.
Wipe system, data, cache and dalvik
Flash custom ROM of your choice
Flash gapps
flash magisk for root if you need it
Wipe dalvik and cache
Reboot.
Setup phone.

I followed your instructions. No luck yet.
After flashing the custom rom, the phone bootlooped.
I changed the data & system to ext4 , I get the failed to mount firmware error.

You really are new to this.
Use the rescue tool.
Let the phone boot.
Skip through setup.
Enable developer options.
Make sure and debugging is enabled.
Connect phone to pc.
Grant always access , which popups on phone.
Open a CMD, in the folder of your adb tools.
Use adb reboot bootloader.
Or use the button combo to get to bootloader /Fastboot mode
Flash twrp.
Boot twrp
Reboot to recovery twrp via reboot menu
Change file system of data to ext4
Reboot to recovery again via reboot menu in twrp.
Now use factory reset, then wipe system partition.
Flash custom ROM
Gapps
Magisk if wanted.
Reboot.
Wait max 10min.
Should work.

I 'm new to this & I appreciate your help, but
I followed your instructions again yet the error remains the same.
My phone is not detecting any wifi or cellular data - so I cant proceed /skip the process of setting up my stock phone.
And when i flashed the custom rom, the firmware error shows up.
And believe me I've tried a lot, but it just wont work.
I've come too far to give up now, any suggestions?

Before flashing twrp.
Use Fastboot oem unlock
.
Try again without custom ROM this time .
I'm looking into it.
Still stuck at the start screen,
I might be wrong but here is what I think is wrong with the phone:
The modem just won't flash therefore no wifi or cellular data.
The firmware is corrupted.
Thanks for your continued support.

Hello, well i messed up my phone really bad. deleted the bootloader. Phone wasnt working. But then used blank flash to get things working again. Just that it only charges now when i run it in bootloader mode. Now what i think u can do is delete all partitions using fastboot. I dont know the terms or words to say, but you can try to delete all partitions and then flash them again and check. use the stock files or what you call those emmc, modem and those bin files that is used to flash via fastboot. It may help but can be risky. Well hope this makes any sense

there is no need to erase your partitions.. Unless you want to brick your device for real.
But you can try it at your own discretion at risk.
i won't help any further since i don't know that much more concerning this kinda problem.
cheers

Hey buddy, I recently ran into same problem as yours. Have you found any working fix for this issue?
Please reply.
Yesterday it happend suddenly: Battery 5% left, just a quick newsarticle before bed and it left me.
At first it didn't even take any charge. Booted in recovery and it's at 40% now.
But booting doesn't work.
OP Logo, bootanimation for around 20 seconds, repeat...
What I tried:
Power off, reboot
changed active slot
Flash the boot image what was last downloaded by me a while ago (semed to be Boot 12.C44_BA, not sure)
Flash the magisk image
Flashed a C47 image
no difference at all, same boot pattern.
A little sidenote:
I have magisk on my op9p, worked fine. a recent ota update failed repeatedly installing in defaulkt way. at boot i had to switch active slot in fastboot a few times. then it booted to current firmware.
I am wondering why i get the same issue independent from the boot.img.
Why did the low battery started this problem at all? How can i be sure to have the right boot.img flashed.
And most important: how can i boot into andoird again?
let me know if you need more information.
Thanks in advance!
edit:
is it possible to install twrp and backup/restore later the important data?
use msm tool and make all new

thanks for the hint! I read about this tool. But this means a full wipe of system and user data, right? any chance to avoid this and rescue images before setting up new?
I see a few possibilities to get closer:
i can boot twrp via fastboot. wiping data seemed to not help.
mounting userdata doesn't work because it needs a pin code which is not my system code.
maybe i have the wrong boot.img? can i find out which firmware version is installed via twrp and flash the right image afterwards?

TWRP doesn't work with A12 only A11 at the moment.
Have you tried getting your hands on the C.62 firmware to local update?

thanks for pointing that out!

what would be the way to update if i have no system access?

Google search "Tool ALL IN ONE" download it and install. Download the C.62 firmware from one of the threads in the forum. Open the tool you installed earlier select generic device from the pop-up. Click on "advanced options" in the tool and that'll bring you to "adb sideload". I hope that works for you!
This sounds promising. I will try that later. To be sure: This will keep personal data like an usual ota update?
Edit: I'm still stuck. Heres what i do: Boot twrp (not install) from fastboot. in twrp start adb sideload. open the toolaio, generic device, advanced options, select firmware.zip and click flash under sideload. Than it prompts "phone is not in adb or fastboot mode". In the main window it show the device id and "adb sideload".
what am i missing?
