Hi everyone.

My OPO's cell signal comes and goes. From nothing at all, to full service with LTE.

Can't continue like this.

Will flashing this work?

Please see album (Notice cell service):

I am currently on oxygen os 2.1.4 and I am not really satisfied with the os. I want to revert back to cm 13. Will this really help me to go back to cm 13?

Me funciono, pero tuve que poner uno por uno, comando por comando. Con el instalador automático solo se reiniciaba.

I had no idea this was a sticky thread! I deleted the links ages ago and haven't really been here in months...if anyone has the files elsewhere let me now and I'll update the OP

My bad!

EDIT: Found the thread by @Spannaa so will re-do the ZNH2KAS3P0 build and post later on

OP updated with the last CM13 files as per the original OP. Hopefully the flash-all scripts work but bear in mind I've not done this in months! Worst case, the files are there so you can flash them all manually if required.

hi,
my 1+1 was running perfectly on march 11th build. about 5-6 days ago i had updated few apps from playstore, after that my phone started going off whenever i opened google maps, drive & whatsapp. so i stopped using those apps but about 2 days ago it went off during call & since then its not getting ON. i tried to recover it as i was able to boot in fastboot but it failed. i flashed color os too or recovery purpose but its not working.
now i am stuck at oneplus one boot logo, it doesn't go beyond that. now unable to go to TWRP even after flashing latest TWRP recovery via fastboot.
is there any chance i will be able to start my phone again ?

Tried this hoping it would fix a no service issue Im having with this OPO and it didnt. Im posting this just in case others want to try it that are having the same issue.

    So, you've unlocked your bootloader and are enjoying some rooted goodness on your phone. You then realise you've got an issue with the phone and forgot to make a backup of your stock ROM! Not to fear, this guide is for you! This will reset the phone back to it's out-the-box state, locked bootloader and all, running the latest ZNH2KAS3P0 build so you can return it for RMA/sell it. This also works to go back to CM13.1.2 from Oxygen OS.

    It's recommended that you have adb/fastboot in your System Path. This makes it easier to run commands as you don't always have to 'in' your adb/fastboot folder to run the commands. This guide should help you with this but if you don't want to do this, please copy/extract any files into your adb/fastboot folder before continuing...

    1. Download the factory image

    Cyanogen released the factory image for the OPO but didn't include any batch files to automate the process. I've repackaged the images into two seperate ZIPs:

    ZNH2KAS3P0 16GB: DOWNLOAD
    md5: be471f6bfc707f86a0af1eb175ec9aad

    ZNH2KAS3P0 64GB: DOWNLOAD
    md5: c371bc0cb4ef67999d21f5275c5a587b

    *** These ZIPs are not flashable so cannot be flashed via TWRP ***

    2. Extract the factory image

    Using your favourite file extraction program to extract the package to your Desktop (I use 7-ZIP). *** Remember, if you don't have adb/fastboot in your Path, extract the image into your adb/fastboot folder ***

    3. Flash the factory image

    Once you've unlocked the bootloader, and rebooted the phone, turn the phone off and back on into fastboot mode and reconnect it to the PC. You can now run the flash-all.bat (Windows) or flash-all.sh (Linux) file. These automate the flashing process. Once complete, the phone will reboot.

    *** Some users have had issues using the script in Linux so in these cases extract the ZIP file and flash each IMG individually ***

    fastboot flash modem NON-HLOS.bin
    fastboot flash sbl1 sbl1.mbn
    fastboot flash dbi sdi.mbn
    fastboot flash aboot emmc_appsboot.mbn
    fastboot flash rpm rpm.mbn
    fastboot flash tz tz.mbn
    fastboot flash LOGO logo.bin
    fastboot flash oppostanvbk static_nvbk.bin
    fastboot flash recovery recovery.img
    fastboot flash system system.img
    fastboot flash boot boot.img
    fastboot flash cache cache.img
    fastboot flash userdata userdata.img (the filename is the same in both ZIPs so make sure you're using the right one for your device)
    fastboot reboot

    4. Reset the tamper flag/lock the bootloader

    There is a flag/bit on the phone that is triggered when you unlock the bootloader and even relocking it won't change this flag back to standard. Luckily, @Mnt-XDA has a script that you can flash which resets these flags so OP/anyone else is none the wiser! To do this, read and follow THIS thread

    5. Reboot the phone

    Says it all really - you're done! :D

    OP updated with new packages :)

    And why do you need to unlock the bootloader to flash the factory image ????

    Because you need access to flash the partitions. If the bootloader is locked you cannot do this. If you're device is still locked from day 1, this guide isn't for you as you're already 100% stock and a factory reset will do this job just fine :D

    EDIT: Actually, it's a bit redundant as why would you need this if you're NOT unlocked! I'll edit the OP

    Looks like this thread will not be continued after the collapse of Cyanogen but if anyone notices a final stock build let me know and I'll do one last repack :)

    Once the 38R factory images are released I'll update the OP :)
