[GUIDE] How to flash the COS 13 update. Even if you get the release keys error

Alright.
I had this problem for a while and I figured out how to flash the update without the need to factory reset or change the update script of the update file.
Even if you get the user/release-keys error message. EXAMPLE:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
You have to be using the latest lollipop release before updating. That means you have to be on YOG7DAS2K1 before attempting.
This worked out for me. But it might not work for you. I do not believe it can destroy your phone and switch some satellites off, but still, not responsible if it did so.
Requirments:
You have to have TWRP now or you at least have ROOT and any flashing app like flashify.
Download COS 13 update file. here https://www.androidfilehost.com/?fid=24459283995316311
Download the latest CyanogenMod Recovery https://download.cyanogenmod.org/?device=bacon
Download the cm-12.1-YOG7DAS2K1 full ROM [url]https://www.androidfilehost.com/?fid=24369303960686198[/URL]
Guide:
Make sure the update cyanogen recovery option is checked in developer options.
Flash CyanogenMod Recovery downloaded before.
Reboot into it.
Use the update function in CyanogenMod Recovery and choose cm-12.1-YOG7DAS2K1 as the update file. It might take a while.
Now reboot to your phone. When booted and running, reboot to recovery.
Now you are running COS recovery. Update with the incremental.
That is it.
I hope this works out for you.
EXTRA: How to ROOT and have TWRP as a recovery:
Requirements:
A laptop.
Download TWRP and adb drivers on the laptop and the SuperSU and TWRP on your phone
Download Oneplus One TWRP Recovery [url]https://dl.twrp.me/bacon/twrp-3.0.2-0-bacon.img.html[/URL]
Get any adb divers. This one suffice [url]http://forum.xda-developers.com/google-nexus-5/development/adb-fb-apx-driver-universal-naked-t2513339[/URL]
Download the latest SuperSu [url]https://download.chainfire.eu/921/SuperSU/UPDATE-SuperSU-v2.65-20151226141550.zip[/URL]
Guide:
Reboot into bootloader: you can do this in many ways. A simple google search will show you how. Easiest way is to turn the phone off and hold the volume up and power long enough for the phone to boot into bootloader.
Connect your phone to your laptop
Run the adb: I assume you are using windows of course. First put the TWRP .img file in this folder. Hold shift and right click in the folder downloaded above. A 'Open command window here' option will be there. Click it and write in the window
Code:
fastboot boot twrp-3.0.2-0-bacon.img
. A hint: you can just write twrp and hit TAB, it will complete the filename. Or you can rename the downloaded file to just twrp.img
Check your phone, you will be running TWRP temporarily. You now have the option to ROOT only by flashing the SuperSU file downloaded on your phone. If you reboot now you will lose TWRP and get back to the official COS Recovery. If you want TWRP for good flash the TWRP file downloaded on your phone before.
I hope this is easy. It actually is. just follow it step by step.

If you could provide us the guide to root and come back to twrp I would be extremely happy

if you need a guide to root, this means you are not rooted, and if you are not rooted most probably you already have stock recovery, which means you can just install the OTA update without any issues.

Thank you, you made my life easier, but when I tried to run the twrp through fastboot I got an error and I got the solution writing "fastboot boot twrp.img" (after renaming the file).

As I stated before you have to be on COS 12.1 YOG7DAS2K1. This method should not format your phone or remove any data as there is no factory reset step.
As for the link they are all over the place now. I used the official one. I'll link it for your convenience.

can anyone please pull the stock recovery from COS 13, not 12. I kinda screwed up while updating and now stuck in bootloop.
Update: The issue is resolved. The issue was because of SuperSu 2.46. Installing the latest TWRP and SuperSu 2.66 fixed it. Marshmallow is now rooted!

Thank you very much! After going back to stock and still not receiving the update for more than a week (well at least it felt like a week, Lol) I decided to flash a full COS 13 zip floating around. Instantly liked the new ROM but it had root/symlink issues only to be resolved when flashing a custom kernel it seems. Not what I really wanted so then I stumbled onto your thread and this technique worked 100%! I was on DAS2K1 (flashed thru a custom recovery) already and had several failed attempts flashing just the incremental outright (thru stock recovery)., but by flashing DAS2K1 thru stock recovery first as you suggest then the incremental seems to do the trick.

I did it all the steps, but my phone doesn't not start. After optimizing aplications I have bootloop at "cyanogen modready".
L.E. I think the problem was one of old aplications. After a clean install everything works.

This is the best thing Oneplus one i ever experience.COS13 give my Oneplus one a new breathe of life .This update better than crap lolipop.No Bug for me until now,only google play service need to update twice in play store,its auto reboot itself twice and wholla,super speed UX.The best thing i ever have.I apply update from CM-12-0-YNG1TAS17L Build LRX22G using this method and it works flawlessly
I don't need to factory reset or wipe cache .
I flash full stock ROM cm-12.1-YOG7DAS2K1 and apply update through CyanogenMod Recovery only and nothing else.
Now my oneplus one is rooted and TWRP install using ADB and its fly.All rooted apps is working together with Adaway.
Thanks Cyanogen team for make this 2 years old flagship killer a beast .
Only thing not satisfied is gone signal and wifi status (connectivity indicator ).I need to swipe down to see my transfer data working (what a bummer ).
Thanks so much for this magical guide (y2kkingboy) Yours truly Oneplus one diehard fan.

I was already on cm-12.1-YOG7DAS2K1, however rooted. So even if I had been offered the OTA it would have failed.
Your guide got me updated, first time with no problems.
6.0.1 is such an improvement on 5.1.1, I tried a couple of other 6.0 roms, however this has by far been the most stable and bug free.
Cheers for the tutorial!

I had tried this before and it did not work for me. Kept getting an error saying "the signature file was not a complete file" and therefore it didn't flash. But it may have been editing error on my part. This method works just fine and no need to give up your data either.

Having tried many other ways, I got it done with this instruction.
Thank you!

Restore Mate 9 Pro that doesn't boot up? Please help

I wanted to root the phone, unlocked the bootloader but flashed incorrect TWRP version and it didn't see SuperSU zip file in the memory. Then I decided to give it up, lock the bootloader back and bring the phone to its initial genuine state. However, the "3-button flash method" didn't work. I downloaded FullOTA zip of B225C636 firmware, unzipped it and moved "UPDATE.APP" file to dload folder in the phone. After using the "3-button method" the phone said "Installation package doesn't exist". Then I made a factory reset from phone settings... and got a non-booting device. It goes to eRecovery which asks me if I want to get an update via Wi-Fi but finds nothing. I entered fastboot mode and flashed boot.img, recovery.img and system.img via ADB Run but nothing changed. So now I can only enter fastvoot or eRecovery. How can I restore the phone? Please help, I understand it's all my fault but I am a newbie with Huawei devices as I was using Samsung where it was much easier before.

Thanks, I tried to flash stock recovery back via ADB Run but it didn't work. The phone was still rebooting into eRecovery partition asking to update via Wi-Fi.
I solved the problem in other way, by setting appropriate DNS in the DHCP section on my Wi-Fi router and then pulling clean B225C636 FullOTA to update server with PC version of Huawei Firmware Finder. Then booted into eRecovery and the process started. After flashing I got my stock recovery back and performed wipe data/factory reset. Now the phone works normally with a locked bootloader as I wanted.

Hi there,
1) Firstly, you need to install the desktop version of Firmware Finder (download here).
2) Then go to the admin panel of your router, enter DHCP section and put 81.177.139.39 as primary and secondary DNS. Write down your original DNS (if any) to restore it later. Make sure that DHCP is enabled.
3) Run Firmware Finder. Open "Common base" tab, enter your model into search window and copy the link for the desired firmware from "Changelog" (see below). You should select the FullOTA version.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
4) Click the round button with a cloud on top of Firmware Finder to open ProxyServer window. Paste the URL you've copied from changelog to this window, click "Set" and then "Register for update" (see below).
5) Reboot your phone to stock eRecovery and connect to your Wi-Fi network. The download and installation should start now.
If the phone is stuck on boot logo after completion, boot into standard Recovery (VolUp + Power) and tap "Wipe data/factory reset". Now the phone should boot up.
Don't forget to restore the DNS in your router's settings.
Hope that helps!

Hmm... Looks strange. This is my first Huawei and I didn't face up with the issue you've described so I can't even figure out the reason... I'd like to know what's the problem with your phone too. Which version and region did you choose in FF? Huawei deletes some of them after a while. Also, maybe there are some ports/services blocked by your inet provider or router?

i have a chinese lon-al00, trying to go to l29
i made the mistake of restoring a oeminfo file for a MHA-L29C636 then tried flashing a update.app via dload - realised it didnt work because i put the dload on a usb with OTG connection instead of a ext/int sd (mate 9 pro dosnt have sd)
Then all of a sudden i lost TWRP, FRP and PHONE is now locked.
Cant boot into system, can only access erecovery and stock recovery dosnt exist anymore.

Oh, you may have corrupted some system data. MHA-L29 is the usual Mate 9, not Pro, and FF seems not to recognize the device you need to restore properly. Maybe you should consider giving the phone to service...

As far as I know, the bootloader unlock code is unique and is stored in "nvme" file located in /dev/block/platform/hi_mci.0/by-name/. Maybe that file was corrupted too or OEM unlock in developer options has gone off.
P.S. The dload (3 buttons) method doesn't work on Android 7 and above. It doesn't matter if you use internal memory or OTG, it will fail eventually. That was one of my mistakes that led to bricking the phone. Never try that again.

[STOCK][N][ARB01] H830 20N ZIPs + KDZ (2017-12-01 Security Patch)

First off, a HUGE thank you to @autoprime (for paving the way) and @waylo (for his assistance on getting this going after I found the KDZ)
I am currently storing these in my google drive account, so please be gentle till I have a better host location:
Below are the downloads for the LG-H83020N firmware
Folder with all the LG830 firmware I have so far:
LG830 (G5)
LG-H83020N-Flashable.COMPLETE-ARB01.zip
As always, COMPLETE is 100% stock
Flash COMPLETE zip -> wipe cache partition -> flash Magisk ZIP (or SuperSU if you insist) to root and keep TWRP
OPTIONAL: After flashing, remount /system RW -> delete recovery-from-boot.p to guarantee TWRP sticks
LG-H83020N-Flashable.Bootloader-ARB01
LG-H83020N-Flashable.Modem-ARB01.zip
LG-H83020N-Flashable.Boot.zip
H830N_00_1017.kdz (HUGE Thank you to @Azul Baseem for the upload)
For instructions, follow the same instructions as you would in any other KDZ/ZIP thread. For Example
Feel free to hit thanks.
Also feel free to hit up autoprime's All in One thread HERE

Thank you very much bedwa!

Kdz link updated!

Thank you @bedwa as always.
I fear my only true contribution here is MD5 confirmation of the files:
LG-H83020N-Flashable.COMPLETE-ARB01.zip 8a49733028bef23d775bf542eb62b726
LG-H83020N-Flashable.Boot.zip ddea9d814f66266de34a154f0c7f6b41
H830N_00_1017.kdz 732b717af8d77501342be445002c4fae
Edit: Also, since someone will definitely miss it in the title, this is confirmed to still be on Anti-Rollback 1. You're free to flash back and forth between 20A if you need to Dirtycow your phone again.

Keeping me honest, I swear I'll remember them next time.

Thanks for the upload. I was able to update just fine thanks to this.
BTW... It still has H83020m mentioned in the body of the OP instead of H83020n.

running 20N , so far so good, just notice a small problem with GPS , it is a bit spotty today. @bedwa : Can you make a slim down version ? like removing LG/TMO/Google stuffs ? and reduce /system partition size ?

That would be trickier. All of these are the partition images. To make a slim zip like that I'll have to either unpack and build or unpack and attempt to repack. I might, but not likely at this time.

Thank you so much for making this. So happy to be rooted and on the latest build thanks to your hard work. =)

I am running on rooted H83020a with TWRP and SuperSU installed. In order to upgrade to 20N by keeping all my current settings and data along with root and TWRP, what are the steps should I follow?
1. Take a complete backup using LG Backup
2. Boot into TWRP
3. Flash Complete Zip (H83020N) from TWRP
4. Flash SuperSU Zip
5. Reboot System
6. Restore the complete backup from LG Backup
Does this work okay? Or, do I need to do anything else, like Wipe Data/Partition etc.? Sorry for the noob question.

Hello,
If I flash boot and bootloader, will it lock my bootloader and brick the phone if I am on LineageOS?

Backup is always good, shouldn't have to restore it as it's updating from a previous version and doesn't wipe data when upgrading. But that's the correct process with or without #6.

Shouldn't, but it would always be a good idea to backup beforehand. I would however only flash the bootloader, as the boot is the kernel and will be different than what LineageOS uses though.

I just boot into TWRP and flashed the complete zip and then flashed the latest SuperSU Zip. I pressed Reboot System after that, but, I am now stuck in a boot loop. Phone shows LG logo and reboots again and again.
I tried the Power button + Vol Down method, but, it doesn't work too. It gets to Factory reset screen, and after Yes and Yes, it goes to back to boot loop again. I am able to get into Download Mode and Fastboot Mode. Can I do something from here?
Can someone help please? Anyway to get into TWRP or recovery?

Sounds like you will need to LGUP or Uppercut your phone back to stock 20A. Then dirtycow back TWRP. Then try flashing the new ZIP again. Skip Supersu this time and try Magisk instead.

Thanks. I flashed back to 20A using LGUP and KDZ file. Need to dirtycow back TWRP now. I'm still wondering what went wrong in my process.
1. Take a complete backup using LG Backup
2. Boot into TWRP
3. Flash Complete Zip (H83020N) from TWRP
4. Flash SuperSU Zip

Do I need to reboot to TWRP once after flashing instead of Reboot System directly after flash? Any idea?

No, rebooting into TWRP wouldn't do anything. There's a script you might need to get into and delete prior to rebooting. But that only ensures that TWRP stays.
"After flashing, remount /system RW -> delete recovery-from-boot.p to guarantee TWRP sticks"
That having been said, I've done this before and STILL not had TWRP stay. Some recommend wiping /cache as well.
OR, again, use Magisk instead and don't use SuperSU.
Even if TWRP didn't stick, you should have been booting into system fine. You wouldn't be rooted, TWRP would be gone, but system shouldn't have been messed up. So something got borked, I'd have to guess, because of SuperSU.

At the moment TWRP tells me it is without software, could you kindly help me?
I would like to install the nxt-l29c432b version ... I tried to get it from AL10 to L29 and this is the result ...
I tried a bit 'of xda-forum and the guides I found were not helpful, because many links with the firmware have expired and Hw Firmware finder are not exactly those of the guide.
I await your feedback,

I tried a bit 'of xda-forum and the guides I found were not helpful, because many links with the firmware have expired and Hw Firmware finder are not exactly those of the guide.
I await your feedback,

This should be easy, if you are not planning on changing region.
Basically you need to find the twrp version for the EMUI version that you are going to run eventually.
And then just flash the files from FF according to the guides.

I would also like to change that if you can ... TWRP I installed it and it works, but when I try to flash a rom, it fails, if I try to update it with vol + and vol - it gets to 5% and crashes.

If you are trying to flash a rom different than the region that your phone is configured for it will fail.
I believe, at least I know it was so before because I done on marshmallow, that you need to change the region configuration before flashing the different region rom.

Hi guys, do you have a TWRP backup of L29c432 that you can restore?

I am having the same issue. Tried to debrand L29 to AL10. Somewhere in between bricked the phone and now I get no os installed in twrp. Tried flashing the update.app , fails at 5%. Twrp says can't mount system,cust,data. Tried flashing the update.zip from twrp. That also failed. System partition is showing as only 2 mb.
EDITkay, I can mount system now, but not data and cust. I tried converting their file system to fat and back to exfat4 but that's also not possible.
Any solutions?

can you boot to fastboot mode? if you can use this command to know exactly what you have. then debrand to the original firmware. flash the original recovery then force restore via erecovery (vol+ vol- power) use same firmware update.app
AL10 can update up to oreo.
fastboot oem get-product-model
fastboot getvar vendorcountry
fastboot oem get-build-number

Finally found a twrp by which I was able to format data . But now it says can't mount system although it can read it. I tried the commans you posted and it says that I have the AL10C00B320 version. But in twrp it says no os installed and everytime I reboot it boots to Huawei erecovery.
This is the twrp which worked for me, incase anyone needs it.
https://androidfilehost.com/?fid=457095661767140812

can't find a AL10C00B320 firmware finder . i found this NXT-L29C432B320
extract :
system.img
boot.img
cust.img
recovery.img
and try to flash this twice via fastboot
reboot to erecovery the factory reset. then force restore using the update.app for NXT-L29C432B320. the factory reset then reboot.

I do have a AL10B320 rom . Flashed it with twrp, says cant mount system . Falshed it via dload. Fails at 5% and says incompatible system. Flashed the img files via fastboot. Everything geta flashed but the phone gets stuck at bootloop. Also flashed the hw update file for AL10B320, same thing.

This is the result of the fastboot commands. I think I have the product model in my phone as next instead of Huawei NXT-AL10 or NXT-L29. If somehow I edit the model version in update.app or the update.zip to be NEXT , then maybe it can install with dload. Anyway to edit the files?
I tried flashing oeminfo.zip fo the l29 version in twrp but it fails. How do I flash oeminfo through fastboot?

did you factory reset after flashing?
extract everthing in the update.app and flash it one by one. verlist.img in the update.app is the one holds the version you can open it via note pad or notepad++ to see whats version. if u succeed in flashing the verlist.img the erecovery might work.

You mean to say flash everything like modem,and all the 20 something img files?
I think maybe there's something wrong with the system partition. I tried flashing kangvip b368 but it says can't mount system partition. I am trying everything to boot to a OS. Also is it possible I change the model of my phone from twrp by replacing files via twrp file manager.

why don't you try dload method..i'm just revived my Mate 8 today after 3 and half days try to find solution after debranding from L29 to AL10..haha..is it on EMUI 4.0 or EMUI 4.1? this is the instructions to solve the problem:-
1. you need to flash stock recovery. Just use SRK Tool by @somboons. Please choose the stock recovery based on your EMUI
2. Try to flash AL10C00B386 https://forum.xda-developers.com/showpost.php?p=69331930&postcount=1338 (download firmware the last link on the thread) by using dload method.
3. If success, use SRK Tools to change oeminfo and custom.bin (need to be unlocked bootloader and root)
4. You can follow the rest of instruction from this thread https://forum.xda-developers.com/mate-8/general/guide-how-to-install-nougat-al10c00b523-t3500327
I hope this will help you bro..

Okay, I managed to fix it. AL10C00B320 was not working, so I thought why not flash an older version. So I dloaded the AL10C00B192 firmware . It reached till 48% then failed. So I thought there's some hope. Flashed the firmware via twrp. Had the same errors but result was successful. Rebooted and the phone is working fine now. It's updating to nougat now . Everything is working fine now except hat sim1 is not working. There was a fix to this.
After I flashed L29C185 CUST sim1 started working but the model changed to NEXT and stopped updating. So after flashing cust should I again change oem and rebrand?

Sorry for late reply..your Mate 8 still can't update?For AL10 it's common problem if you debrand from L29. Try to flash another stock firmware from FF that have FullOTA-MF. That is might be working for you..Just try it first..

Glad to hear it..when i changed to AL10 or DL00 there are a few settings that are not in global firmware..i think it's only for devices in China

Hi guys, forgive my incapacity.
After all this time my Mate8 is still unusable.
I tried to follow the steps I found here, but trying to load via dload the AL10C00B386 arrived at 35% then it stopped.
I would like to get the NXT-L29C432B581 or later ROM.
The basic phone is a Chinese al10.
I know to ask you a lot, nobody could make me a step by step guide or upload a backup from TWRP ???
thank you all

Hi Friend, You can get your firmware in Firmware Finder app available on Google Play store.
Dload you did with files on SD card and not internal storage, I hope. If not, put it in SD card and try.
Sorry, I read your previous messages now. Let me know your Original build i.e., AL, DL, or L29. Which last working rom you were on and what you did after that.

So basically it is not able to install EU rom on a device with CN rom ?

im wondering why the file ends in .ozip vs .zip maybe thats why?
EDIT: I didn't realize that is a oppo specific update extension,so im not sure why it wouldnt work
maybe unlocking bootloader then flashing via recovery will work?

I would have thought this was expected? The same was the case with the X2. Unless you can fool the recovery somehow in to thinking you're on a global version I would imagine it's unlikely this method would work.
I assume flashing through TWRP with an unlocked bootloader would work but that's not going to work with this proprietary ozip.
I don't think anyone has tried a full twrp system backup and restore from a global phone to a china one though. I'm interested in how that would play out.

Ozip to zip is easy. Done.
BUT, both fastboot flashing and twrp flashing giving errors, because new (EU) system.img and vendor.img is larger than CN versions.
I can go further, try to flash EU recovery and flashing ozip rom. BUT I'm afraid if device is bricked, I don't want to wait for months hoping for a unbrick rom

ozip update is normal that means is a oppo realme update even the CN version ends with ''ozip''
But yeah can't install it in ''normal way''
is there a way to unlock the bootloader and intall twrp? I didn't see anything ''official''
Otherwise how to guys?

1. ozip decrypting
2. compatibility.zip must be delete
3. sign zip and flash (but I think recovery will flash to eu version so it may cause some problem)

Hi
I'm in the same situation as you are. Should get my X2 pro these days and am collection information about safe ways to root, because I need my phone as working phone and unfortunately can't take the risk ofbricking the phone or have an unstable installation. As far as I know for shure:
Unlocking bootloader
You need the tool "In-Dept test Tool" on your phone. Read this . You will find a download link there.
Installing TWRP
There is a pre-release version from honorable @mauronofrio. I don't know how big the risk ist to install this. I haven't read anything about people who have experience with this. For instructions read this .
Rooting
Now we are on the tricky point. I have not read anything about succesful rooting. Neither with Magisk nor with SuperSU.
If anyone has additional info or newer info please let me/us know.

Extracted EU rom to system.img + vendor.img + other partitions. BUT the system.img is 5.1GB, CN version is 4.4GB, same for vendor.img, is bigger. Now both fastboot flashing and twrp flashing are giving errors, that there is no space for flashing.
I need help, is there any way to resize those partitions ? (twrp resize does not work).
