Generally speaking: Install bootloader only with Odin.
You should now flash firmware using Odin to save your device. Maybe Kies could restore also.

HERE you may find firmware for your country/device, download.
Start Odin, connect your phone in download mode to pc, see if Odin shows up com-port and flash firmware in tab PDA/AP.
There are several guides on youtube/google

Cant Find my carrier
my carrier is international, only countries are on that list, I dont know which one to choose, also if im gonna flash firmware is it possible to flash 4.1.2? or 4.2.2/4.3?

Depends on your last firmware. What was the bootloader version? If above MJ5, you can't downgrade so you are free to flash eg latest 4.4.2

1. Never flash bootloader through recovery
2. I assume that you have had newer bootloader than MJ5 before flash, so you soft bricked your device
3. To regain full funtional device follow post #4

Bootloop after flashing stock image

Hi guys, my nexus 5x is locked bootloader and i was running the last Android 7.1.1 stock. I decided to try the last CM14.1, entered TWRP and made a backup. I installed CM14.1 and gapps and my phone was in a bootloop. I decided then to restore my backup, restoration was successful but when i pressed reboot system, I was in a bootloop, at Google dots logo. I flashed successfully the DP 7.1.1 image but couldn't get out the bootloop. Flashed the last stock 7.0 image with the same result. I can access fastboot and recovery but until now couldnt get my phone to start and get out this bootloop. What can I do? Is it a hardware issue as i read somewhere on XDA?
Any help and advices please, I live in a country with no Google service center and I am desperate.

If flashing full stock (all not only system) and full wiping doesn't solve your issue sounds like the infamous hardware problem.
Make sure you didn't restore efs backup taken with twrp 3.0.2.1 otherwise look for efs fix.

You can't.
If you have a locked bootloader all you can do is to flash a full ota package from stock recovery and to wipe/factory reset if it let you to.
If it doesn't fix your issue unfortunately you have to RMA the phone.

when you restored from your backup, was EFS checked when you restored? if it was then you have an EFS file corruption. I personally wrote up a solution to this, here's a link: http://forum.xda-developers.com/nexus-5x/help/efs-file-corruption-fix-t3502473
make sure you follow the instructions, this has to be done with the Nexus root toolkit command window open with your phone in TWRP recovery and hooked up to your computer. if you try this, let me know how it goes and if you need help.
edit: your bootloader is unlocked which I know for sure, you can still boot into bootloader and re-root and install twrp back onto your phone even though you're boot looping. I know because the same thing happened to me and was still able to flash a custom recovery.

Yeah it is the EFS problem related to buggy versions of TWRP. Just use dd to to clear the EFS partitions - the chipset will luckily autogenerate the EFS contents on first boot.
Next time dont restore EFS partition from your backups and everything will be perfectly okay.
Makes me wonder how many hundreds of people have sent the device to RMA because of this issue.

This command is to unlock the bootloader right? But I guess if the OEM unlock is not selected in developer options within Android, it won't work, or correct me if I am wrong.

You can try. I heard somewhere that it may work if you apply it before booting the android the first time (technically your android cant boot at the moment).

re locking bootloader is possible. flash raw firmware. or flashing boot, recovery, fastboot and ifwi images.
@DarkshadoW99 very first of all you started new thread without searching around. and if you started a new thread your post is too confusing or lacking the context of your post. unable to understand what you actually want.
very first of all while unlocking bootloader with unofficial method. you may get error " failed too many links" but even though bootloader is unlocked pretty well.. ( mention which tool you are using to unlock bootloader)
second thing is you stated that you are trying to unlock bootloader to access recovery. what does it actually mean? do you want to flash custom recovery or your are unable to enter recovery mode?
"in marshmallow if you boot with unlocked bootloader the phone stuck on asus logo" what does this line means? are you stuck at asus logo? as far as i know you can boot in MM with unlocked bootloader too. unable to understand what you wanted to say.

Go back to Lollipop for bootloader unlock

Since there isn't any OFFICIAL unlocker for Zenfone 2 Marshamallow, your best bet is to go back to Lollipop abd having an unlocked bootloader but again, it'll be without Marshmallow:
Download official firmware latest release or whatever you had BEFORE installing LineageOS. Rename the the file you just downloaded to:
MOFD_SDUPDATE.zip
Click to expand...
Click to collapse
and put it on an SD-Card, put the sd card in your phone, boot into recovery (by booting to fastboot and selecting recovery) and the restore should start automatically.
Now at this point you'd be back to stock marshmallow and you can downgrade back to Lollipop ( V52.20.40.197--be mindful the link is for the JP SKU and you need to download the right SKU version for your phone in case you have WW --didnt see you specify or not, so maybe you want to check you downloaded the right Lineage OS as well as maybe thas why its freezing ) to use Asus' Unlocker.apk [You can find instructions on official Asus website under support]

If the last thing he installed was LinOS then he has twrp for recovery. I don't think that method will work.

That's a very valid point, but since his post is vague and quite confusing, unless Lineage has a function within the ROM to "relock the bootloader" I would've assumed he "relocked the bootloader" by installing/fastboot flashing some official boot.img and since he cant get into recovery and his bootloader is locked, I had imagined he'd be back to stock fastboot.
but meh, my guess is as good as any. Unless the OP adds some clarity, we can at least say we tried, amirite?

Looking for NPPS25.137-93-14 fastboot firmware

Could somebody provide full untouched fastboot firmware with build number NPPS25.137-93-14 for DualSIM Moto G5 (XT1676) with reteu software channel and 3GB RAM/16GB ROM, please? Thanks in advance.

https://forum.xda-developers.com/g5/development/official-stock-moto-g5-cedric-firmware-t3733897

I have been looking for it during several weeks too, no success until now. I found 137-92-14, which is built for other software channels. It works well in my XT1685 (Dual sim 3GB/32GB reteu).
Still looking for 137-93-14... Regards.

Doesn't XT1685 equal G5 Plus?

You can flash older recovery without bricking the phone. However, don't do that if you are running CustomROM. In my case, when I wanted to revert to fully updated stock, I flashed NPPS25.137-93-8 firmware without gpt, bootloader (that's what would brick the phone if flashed) and erase modem commands, updated it to NPPS25.137-93-12, then to NPPS25.137-93-14 using stock recovery and these files https://drive.google.com/drive/folders/1BkpfHvgQ477NViLYvzgv88Fgq3SSt5Py. No issues at all and my phone (XT1676, 3/16, DualSIM, reteu) is still working fine.
In the attachment, I'll put recovery.zip (with recovery.img inside of it) of the NPPS25.137-93-8. Use at your own risk, if you are interested.

But thing is: I'm currently on NPPS25.137-93-12 with TWRP and Magisk. As a proof of concept I want to go to *-14 via OTA to see if it is possible... And if so: to make the oreo jump when available for my channel (XT1671, 2 sim, retla). I want to avoid losing all my data or any long task that would keep me offline for a long time... Daily driver both work and personal...
Uninstalling Magisk reverts boot.img to stock.... but I still need the stock recovery.img to be in 100% stock state (but unlocked). That's the theory.
Tried yesterday using other recovery.img versions, but failed: /cache/recovery/last_log shows the Blur* OTA file updater-script explicitly checks recovery version to be either source or destination versions... So *-12 or *-14.
After that, updater-script checks boot, system and oem. Those are (will be, supposedly) stock since Magisk only patches boot.img and I'll uninstall it .... should work...
The longer path of flashing other version and do the OTAs is also possible... But I'd have to be on vacation or something...
Thanks again.

Try one more time with file in the attachment of this reply. Although you will get "Image signed with key bad key" (because it's simply extracted from NPPS25.137-93-14), it should flash just fine. In my case, I've tried to flash it with fully updated phone to NPPS25.137-93-14, no issues at all. However, you should be more careful if you are running .12 firmware - this is stock and newer recovery (recovery of .14 firmware). .
Okay, so there are already 2 files in the attachment, first one contains recovery.img of .12 firmware, second one of the .14 firmware. You can recognize them by name of the file. With each of them, you will still get "Image signed with key bad key" message when flashing, but they flash just fine and everything seems to be working flawlessly on my phone with coresponding firmware version (means .12 recovery for .12 firmware, .14 recovery for .14 firmware). Once again, you are doing it at your own risk if you decide to.

Thanks. I'll test tonight.
"Bad key" is no problem... Got it twice already by testing with other versions I was able to get.
As for it being from *-14, it should work if I believe the updater script checking for either *-12 recovery (source) or *-14 recovery (target)... We'll see.

Another question: are you extracting them from your own phone? If so, how? Untill now I only found possible by rooting, but rooting means changing recovery in first place... So... Hen and egg...

Yes, I rooted my phone by Magisk and used app called Flashify to backup recovery. However, to root, I didn't install TWRP permanently by "fastboot flash recovery twrp.img" command, I just booted into it by "fastboot boot twrp.img", so I was able to root my phone and keep stock recovery installed.

Thanks. I had been reading about it and some posts were misleading saying it was no longer possible and others said it was. Had not gotten down to test it yet. So now I know it works, I'll do it. Thanks again.

Update: tested.
good: Recovery image -12 worked without issue and updater-script check passed.
bad: it failed while validating boot.img.
Apparently, Magisk uninstall did not restore the boot partition to stock. I also had a TWRP backup from when I had just unlocked. Restored boot. No luck. Maybe I took the backup *after* rooting.
well... I guess I will have to wait until I have some free time to do the long way: full flash
EDIT: @Andrej_SK: would you by any chance have the boot.img of *-12 too?
thanks!!

You can relock bootloader and whatever you like.
Have fun enjoy.

Thanks a lot. This tool won't work if you have lost your IMEI, but it allows you to download the latest firmware (in my case 137-93-14). Using this full stock firmware I have been able to recover the IMEI following the steps explained in other topic in this forum.
Regards.

I might give it a try, if you give me some time.

Question Locked bootloader while in download mode boot loop

Hey i was attempted to install TWRP and got stuck in download mode boot loop. Fixed it by flashing stock firmware. I noticed a small error with my camera so i tried to lock bootloader again to see if that would fix the issue. But after flashing stock firmware a second time after locking the bootloader it didnt work and im stuck in download mode boot loop again. Only this time i dont get the option to unlock the bootloader and i cant enter the OS in order to enable OEM Unlock.
Here is the error screen: https://prnt.sc/q8vmG--mTHxY
Anyone know how to get out of this mess? Thanks

Am i doomed?

You can't lock your bootloader when your phone have unsigned binaries such as TWRP/Magisk installed. Have you tried to flash again the stock firmware (BL/CP/AP/CSC)?
EDIT: by looking at the error it seems like your bootloader and vbmeta aren't from the same build (bootloader: DVK5, vbmeta: DVL2), I highly suggest you to flash the latest firmware available for your country

Shouldn’t be a big deal unless there’s something Carrier specific required by your phone. Just make sure you don’t lock your bootloader again while using custom binaries or you might soft brick your device again. To bypass the camera lock you can use a SafetyNet fix module for Magisk which will spoof the bootloader status to the camera HAL

Am i supposed to flash only AP or all of them? I have only ever flashed AP and worked without problems but after locking the bootloader i only get the above error boot loop.

The error in your device happens for this exact reason: vbmeta partition in the AP tar can’t verify other system binaries since they’re older and you didn’t update them (DVL2 vs. DVK5). First flash the whole firmware package via Odin (BL, CP, AP and CSC), if you wanna root your device make sure you flash TWRP+a patched vbmeta image to avoid this error to happen again. Also do not relock your bootloader again while your phone has custom binaries flashed, if you wanna lock your bootloader flash the whole stock firmware package before.

I dont know if im using the right files but i still get the same boot loop (https://prnt.sc/1lCk2FQEymPn) after adding twrp-3.7.0_12-2-a52sxq.img.tar to AP and vbmeta_disable.tar to USERDATA.

Are you flashing the patched vbmeta in the TWRP XDA thread or another one? Also the latest TWRP version is 3.7.0-3 so flash that one.

Im using the vbmeta from this thread: https://forum.xda-developers.com/t/recovery-unofficial-twrp-for-galaxy-note10-lite-exynos.4350891/
I tried flashing that along with this: twrp-3.7.0_12-3-a52sxq.img.tar
But i still get the boot loop. Not sure if i can keep trying to re-flash these if the boot loop already happened

You must use the patched vbmeta linked in the a52s TWRP thread, flash that one and you should boot fine in TWRP.

I think it has something to do with the space in “New folder” name, try to copy the TWRP tar in a path that has no spaces

Oh yeah good catch, i renamed the folder and didnt consider that it might not be updated it odin. It finally worked, thanks again for the help very much appreciated

Hmm i guess problems keep popping up. I guess its best that i just post here instead of creating a new thread. Im successfully in the TWRP UI but now i cant boot to system, it will just restart 2 times and then boot to TWRP. Also it fails to backup the boot image (with the error "Unable to mount storage") which i read in a tutorial that you were supposed to do.

As mentioned in the TWRP thread guide, you must format your data partition in TWRP in order to be able to boot back in the OS.
