Hi all,
I'm sorry to ask this question, but I'm really struggling to get my Nexus 5X to boot into stock rom. The install seems to go ok, but there was error when flashing.. See below...
archive does not contain 'boot.sig'
archive does not contain 'dtbo.img'
archive does not contain 'dt.img'
The phone now boots to the google boot logo, then loops back to either the "Unlocked Bootloader" or the Custom OS message. (depending on the locked state of the bootloader)
I cannot get into recovery, as the phone just loops back as described above when selecting it from the bootloader option.
Can anyone advise me on how to restore the phone back to stock os. I've tried flashing version 7.1.2 8.0.0 and 8.1.0, using either the flash-all.bat or manually typing the commands. I'm 110% sure this is not to do with over heating on CPU/RAM, I have another nexus 5x that has the bootloop of death and it's bootloop is very different from what I'm seeing on this Nexus 5x.
Thanks in advance
First, the .sig errors are normal so you can ignore those. I would make sure your booloader is unlocked then manually flash the bootloader.img. Then boot back into the bootloader. Then manually flash the remainder of the partitions. Use the 8.1.0 os.

Ok here's what I've done.
1) Downloaded bullhead-opm2.171019.029.zip from Google factory images.
2) Extracted the zip to a folder and extracted image-bullhead-opm2.171019.029.zip to the same folder to get the boot.img | system.img | vendor.img and recovery.img file. (there was no userdata.img nor cache.img within the zip, so I downloaded 7.1.1 version and extracted those files too)
3) Using SDK tools ADB /Fastboot version 1.0.38, I flashed the following:-
fastboot flash bootloader C:\bullhead\images\bootloader-bullhead-bullhead-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\bullhead\images\radio-bullhead-bullhead-xx.xx.img
fastboot reboot-bootloader
fastboot flash boot C:\bullhead\images\boot.img
fastboot erase cache
fastboot flash cache C:\bullhead\images\cache.img
fastboot flash recovery C:\bullhead\images\recovery.img
fastboot flash system C:\bullhead\images\system.img
fastboot flash vendor C:\bullhead\images\vendor.img
fastboot flash userdata C:\bullhead\images\userdata.img
fastboot oem lock
Everything flashed without a problem, no error. However the phone still does not boot into the OS nor can I get it to boot into recovery mode.
I cannot understand what I am doing wrong. I think it has something to do with the installation of copperhead I tried. Does anyone know whether copperhead os restricts going back to stock rom due to its additional security features?
I'm stuck!!!
Thanks in advance.

Why don't you use the "flash-all.bat" file? I'm pretty sure you're not wiping your system partition in the process you use.

Hiya,
I have also tried using the .bat script, it leads to the same place. A phone that does not boot.
thanks in advance.
Can you boot into twrp, fastboot boot twrp.img? If you can try formatting, not wiping, the data partition. It also gives you the option to repairing some other partitions, I don't remember which ones. You could try that.

SO, i'm trying to ADB sideload the latest firmware (MRA58V), but when I go to the google developers website, it downloads in a .TGZ file.
https://developers.google.com/android/nexus/images
I've tried changing it to .ZIP, then flashing, but it fails invalid signature.
What am I doing wrong?
Thanks,
Thread moved to proper forum
Simply flash the .img files inside the zip with fastboot. Takes 2-3 minutes.
Since only boot and system changed that's all you need to flash.
The commands I used today for 6.0.1:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot format cache
fastboot reboot
That's it, doesn't wipe anything.

All,
I am not a noob by any means, but when I attempted to manually flash the img files via fastboot for the latest N build from the factory images coming from the last 6.0.1 build I get stuck on the Google logo. I checked the commands and re-flashed again and the same result happened ( i did flash radios and BL ) .
I even tried to format data ( i had backed everything up ) , still no go and stuck at google logo still. I could access BL and able to access TWRP.
I got frustrated and flashed the 6.0.1 images including BL and radio via fastboot and booted up just fine. I then rooted, installed flashfire and used the OTA and Android N installed just fine.
Does anyone have any idea what could be causing this. I am currently on N, but wanted to do a clean install .
Thanks in Advance
Did you flash vendor.img?
Why don't you list the exact commands you used to flash, then people can comment.
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash boot boot.img
fastboot erase cache
fastboot flash cache cache.img
fastboot flash recovery twrp-3.0.2-2-bullhead.img
fastboot reboot-bootloader
fastboot flash recovery twrp-3.0.2-2-bullhead.img
Flashing mtc20k works successfully
Using the same commands to flashing npf10c results in stuck the google logo
In order for me to even get on N I have to me on 6.0.1 then either use the bullhead-ota-npf10c-d1785fea.zip on the root of the SD card and use flashfire OR use the following command from stock recovery
adb sideload bullhead-ota-npf10c-d1785fea.zip
The later is what I did recently, but both will work to get to N.
So why can I not simply flash the factory images like for 6.0.1?

I have tried fastboot erase userdata and fastboot format userdata and fastboot erase cache
fastboot format cache and that never worked.
I tried that factory image before and resulted in the same, however, I will at sometime attempt to do the final of 7.1.1 once it is available sometime in December 2016 and hopefully will resolve the issue.
I will stay on DP1 right now as i find the battery extremely excellent, the Visual VM is back now, and i notice some notifications are coming through better than in 7.0. (I read an article earlier today about notifications and the pixel not coming through)
Thanks in Advance for the people that did come through so far and wanted to thank you for your input on the matter and if i don't have a pixel by December I will try this out.

Hi, because you should not flash bootloader.
you can try those 2 solutions:
the fast one, it should work. The flashall command flash every.img files he find in the fastboot directory. So try to remove the bootlader.img and execute the flashall command.
the manual one (longer one):
Put only the recovery.img, boot.img, and the system.img files ( you should have something like 13 , named "systemchunk0/12.img") in your fastboot directory and flash with fastboot ( the command is always the same: fastboot flash recovery recovery.img, fastboot flash boot boot.img, and for every single part of system.img you should flash like "fastboot flash systemchunk0(until 12).img " so you flash flash 13 times the system with avery 13 parts .
Sorry for my english i hope you solved that

Ah ok i didnt understand that you have this modem issue. I don't kno how to help you...you phone is bricked so you can test few solutions without more risks .
before flash the original recovery , boot and system by fastboot, you can try to install TWRP again and flash only the bootloader from TWRP (should support .zip and .img files). Then you turn the phone in fastboot mode and flash other stuff .

So you screwed up and didn't follow Rule Number One in the IT-Handbook?
Which is: Always create a backup before working on a system?
Download the Factory State Images. Which are all flashable with fastboot: https://goo.gl/JTCwKj

pause
Extract all the files listed in the BAT file or simply extract the entire archive to ADB / Fastboot and launch the BAT file.
Does this work?? @Undesirable
the above post
Oh yeah, it unbricked me and put me back to stock so I could get OTA updates for Nougat. You need the archive posted earlier in the thread though.
@Undesirable Nice and elegant solution man! Typing all this stuff was so annoying.
For those who need an alternative download source, I offer this magnet link:
Code:
magnet:?xt=urn:btih:ef05ea3af4da8a0cbb137c10621942f3ae16d46f&dn=P2a42_S048_161111_ROW_fastboot.7z
It's slow unless lots of people help to seed it.
Is it possible to flash this firmware 2a42_S048_161111_ROW_fastboot.7z on the P2c72 with firmware build number: V3.5_1652_5.1342.1_ST_p2c72 ???
I bought this phone 4GB Ram/64GB from china, but I want to put the international firmware on it.

how can I replace my data partition? It's not getting formatted due to an encryption error
If fastboot erase userdata doesn't work, then use TWRP to change user data file system to EXT4 then change it back to F2FS again.

I flashed back the stock ROM (due to encryption error in custom 7.0 ROM) using fastboot commands, but my SIGNAL WON'T WORK after I started d phone .

I've flashed 'ROW' variant of stock ROM. Is there a different version for Indian variant?
Hello all,
I'm a bit confused about the process of taking my current '3' ROM and changing it to the official Lenovo Rom.
I have downloaded the lenovo drivers (installed and ok) phone is in debug mode.
I have downloaded the stock rom from here: https://forum.xda-developers.com/lenovo-p2/development/7-0-lenovo-p2a42-stock-nougat-update-t3581517 and have adb / fastboot.
I know I have to use the volume rocker and powerbutton to get into the boot mode but I don't know the commands for adb or fastboot. I have changed the name of the rom to 'update'
Can someone please advise me on the commands I am meant to enter to get this onto my phone please?
Thanks in advance,
Cue
Copy all the code below, paste it to a new text file on your PC and save it as All Files instead of .txt and name it a fastboot.bat. Place the fastboot.bat in the adb/fastboot directory, also place the unpacked rom in the same path. Run it as admin. Profit.

Hi, op here.
Firstly, thank you for responding! Your instructions seem very clear. When i had a look at the contents of the ROM (in zip) i couldn't see any of the systemchunk files you mention, are they hidden deep somewhere?
Regards,
Cue.
If your phone is stock the Rom can be updated without fastboot or a PC.
All the instructions are in that thread.
Huh. Surely just boot into recovery and install the update.zip? No need to have it connected to pc.
Hello all,
Yep. I un-encrypted the sd card copied the zip onto it and booted up that way. Very easy. Now running stock directly from Lenovo which I am very happy about! It also pushed the new 78mb update as well.
Thank you for all your input.
same way i did it too theirs no need to do it through fastboot method just like the other people i did it through the built in recovery by renaming the Nougat rom to update.zip works fine and you will get another update ota straight after t obring it right up to date.
Sounds like you guys have this sorted :highfive:
Just for completeness, can somebody upload the original 3 rom? It just helps out the person who thinks they have a hardware issue and may need to return the phone to 3.
If you try and return your phone and it doesn't have the original 3 rom, your chances of a good outcome are obviously less as you have tampered with the phone etc.
The warranty is with Lenovo Not three.
Doubt there'd be an issue as the bootloader will still be locked and it's an official Lenovo Firmware.
Since flashing nougat and a factory wipe my VOLTE is now working.
I did the same flashed nougat and volte is working but only shows up some times not as much as I'd like is their any way to get volte to work more often. In my bedroom where the signal is weak I don't get the volte symbol at all.

Sorry My Bad @Homeboy76
Have you tried these steps below?
If you have modified a little the stock android (hosts file, root, kernel, etc.), you may experience a fail in OTA update;
If you have a bootloop/soft brick/not sure of the state of your android system;
This WILL NOT delete your data and apps. This will remove your custom kernel/root/hosts/recovery through (which is a good thing because it will be clean then).
1) Download your system image for Marlin (Pixel XL) on google website.
download the latest version
2) Unzip the file marlin-nde63v-factory-______.zip
3) Unzip inside the new directory (marlin-nde63v) the image-marlin-_____.zip
Execute fastboot commands (assuming the bin is on your PATH)
Code:
fastboot reboot-bootloader
fastboot flash radio radio-marlin-*.img
fastboot reboot-bootloader
fastboot flash boot_a boot.img
fastboot flash boot_b boot.img
fastboot flash system system.img
fastboot flash system_b system_other.img
fastboot flash vendor vendor.img
fastboot flash modem modem.img
fastboot reboot
to add TWRP;
fastboot boot /path/to/twrp.img
then In TWRP, install twrp.zip for permanent twrp. Goodluck!
