How easy is it to switch from EMUI to LineageOS? - Honor 8 Questions & Answers

I see the AOSP ROMs don't support encryption and I believe EMUI is encrypted by default. Is it easy to go back and forth from stock to AOSP? Also, is there an easy way to flash EMUI over TWRP? I see some really good prices for this device and thinking about picking it up.
Thanks!

Yeah, it's easy but it takes time go to a custom rom and come back again

Just have a TWRP backup of EMUI and switch easily any time

Yah it's easy. The best way is to use the rebrand way. To rebrand to L9 or L19 as they get updates way quicker. All you have to do is flash the rebrand zip and your back on stock everything!

Do you know if this would work on the FRDL04 or FRDL14? I think those would be the variants I would use.

[Stock][d800][AT&T] Lollipop D80030F - Partitions

Dump of Stock Partitions
Lollipop d800-30f​
Since we don't have a d80030f KDZ or TOT yet, I decided I would try to do the next best thing. I did a back to factory 20c -> 20y -> 30f upgrade progression. Then I did a factory reset, followed by one click root. Then I dumped all of the partitions that are normally part of the KDZ.
The zip includes Stock 30f images of:
aboot
dbi
laf
misc (removed, not needed - specific to each phone)
persist
rpm
sbl1
tz
I have the modem partition, which will get its own zip and its own post. (http://forum.xda-developers.com/att-g2/development/modems-att-stock-modems-t3106221)
I also dumped system, but it is huge. Please don't download it if you're not a ROM maker (it'll make Google mad at me): https://drive.google.com/folderview...NEb0dUVlpQenhrOHZsaGYyQ3ZiOGV0LWM&usp=sharing

Here ya go.
Flashable zip of the whole ROM will be soon (probably work on it tonight).
@blastgator, what will be the difference between your flashable zip and the stock OTA, other than the fact that it's a zip? Also, do you find it preferable to use stock LP on our device vs BlissPop or other 5.1.1 ROMs? I spend a lot of time and computing power building nightlies, want to know if it's pointless. I don't think so, but now that we have LP, I needed to ask you. PMing you!

I still run KK. I am just doing some of this stuff to get ready for the upcoming move. I was going to start looking into ROM creation, based on stock ROM (since we don't really have any at this point).
Therefore, I don't really know the answer to your question - "is it worth it?"
And yes, the zip is just what I recovered after doing the FOTA. Much easier grabbing these instead of having to flash 20c and then force 2x FOTAs.

that's exactly what i was going to say, i don't use blisspop, i don't like custom roms, i prefer stock experience and i cant upgrade since im not on AT&T network, and what he is doing is exactly what i (and many others alike) need, a flashable zip of the Lollipop update

I slapped a zip together earlier for the stock ROM - it wasn't cooperative and made me mad so I gave up for the evening. Kept getting error:
E: Failed to sysMapFile
It was >2GB so that might have been part of the problem.

Exactly what I'm looking/waiting for as well. 100% stock Lollipop rom in a flashable zip format. Well, a debloated version would be better but I'll debloat myself if need be. Our Devs are amazing, I'll hang tight and wait for it
Awesome, thank you so much! There hasn't been much movement for a stock LP ROM for the D800, so I'm glad you're doing it!
<Deleted> Test build info was here.
blastagator said:
If any brave testers dare:
http://blastagator.ddns.net/testing.php - beta1
It might not work! Please make sure you know how to recover!!!
I would not post something I would not try on my phone.
HOWEVER, I have NOT tried this on my phone because I had some family issues come up and I can't be "off the grid" so to speak to test things in recovery.
This flashes 20y bootstack, 30f modem, 30f system, and 30f bumped boot.img. Nothing else /should/ be modified. Root may or may not work. It appears installed, but you may need to run "One-Click-Root" or some similar thing after install.
Also, I modified nothing other than root and doing a bump. FOTA will still be functional as well as any other nasties that could cause issues down the line. This is STOCK!
If anyone tries, please report back, for everyone's sake.

Question can i flash that from 20k? or do i need to be on something specific?

I downloaded the beta earlier but ran out of time today to do the install. Before I get brave and attempt it tonight or tomorrow, has anyone done it already and if so what were the results? Thanks.

Didn't work. I had a bad update-binary in there. Once I fixed that I kept playing mix and match because of fastboot error. Still no luck, and needed my phone back. I'll tinker more later.
Tried full 20y bootstack. Tried just aboot and laf 20y, rest as LP. Tried each of this with bumped and unbumped stock LP boot.img.
Bumping gave me a padding error, guessing it might be partially related to that. Unsure.
Thanks for the update, saved me a few headaches I'll hang in there until you get a version that boots. Thanks for doing this!

Thank you @blastagator for all your help. No rush. To know someone is looking into it will hopefully spark some interest in the d800 community! Once again - your contributions around here have been invaluable.

[GUIDE] Debranding to C432 and updating to B361 (Nougat) for EVA-L09

Like many people here, I was eager to get onto Android 7 but the issue I faced was the fact that I got a branded phone and a long wait till I officially get the Android 7 update. Looking through this forum I was very put off on manually updating it to Android 7 with so many threads about bricked phones. However, the urge to get onto Android 7 was too great so ultimately, I decided to do my research and just do it. I am not new to flashing and custom roms but I am new to Huawei but I had confidence that I will recover if I do brick my new P9. In the end (after a few bricks and a couple of mild heart attacks), I got there and to get there, I needed to grab information from multiple threads. So I have decided to put together this guide so people have a singular guide to debrand and get onto Android 7. Below are steps and threads I took to debrand my C34 to C432 and update it to B361.
What listed below is what I did to get onto Android 7, this may or may not work for you so use this guide at your own risk.
Using this Guide - Please read through this guide BEFORE attempting it. There is a lot of large files to download so I recommend that you download everything you need before you make a start and a fast and reliable internet is strongly recommended.
Prep Work
- Backup all your data because your phone will get wiped.
- Make sure you have the stock recovery already flashed and make sure your phone is not rooted (may not be necessary but this was the state my phone was in).
- Get yourself a bootloader code from Huawei. Go to http://www.emui.com/en/plugin/hwdownload/download, you will need to create a Huawei ID if you haven't already done so. Click on the Unlock Bootloader link and fill out the form, you should get a bootloader code almost instantly after submitting the form.
- Download and install HiSuite (http://consumer.huawei.com/minisite/HiSuite_en/index.html).
- Download the SRK Tool from here: https://forum.xda-developers.com/showpost.php?p=66737472&postcount=2
Now lets make a start.
1. Download and flash the dload-huawei-p9-eval09-eva-b136.zip from this thread: https://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818. Instructions on how to flash this is in the first post. After flashing, you should be on the L09C900B136 firmware. NOTE: If it boots up to a white screen asking you to enter password, reboot into recovery by holding volume up when you powering up your phone, do a wipe partition and factory reset. You may need to reboot your phone a number times before the phone boots up correctly.
2. After flashing and booting into the L09C900B136 firmware, you will need to unlock your bootloader and install TWRP. You can use the SRK Tool to do this, please have a look at this thread (https://forum.xda-developers.com/showpost.php?p=66737472&postcount=2) and watch the video on how to do this. NOTE: You only need to unlock bootloader and install the TWRP recovery.
3. After your phone has been unlocked with TWRP recovery installed, download oeminfo-huawei-p9-eval09-c432.zip from this thread: https://forum.xda-developers.com/p9/development/c432-oeminfo-flash-twrp-t3384903 and flash it via TWRP. To get into TWRP, power off your phone and go into recovery by powering up your phone while holding volume up.
4. Once you flashed the oeminfo file via TWRP, power off your phone and repeat step 1. So you need to flash the dload-huawei-p9-eval09-eva-b136.zip file again via the dload method (power on the phone while holding volume up and volume down). NOTE: When you flash this firmware again, it will lock your bootloader (Fastboot will tell you that the phone is unlocked but I assure you, your bootloader is locked) and restore to stock recovery.
5. Once your phone has booted back up, go into the phone settings and you should see that your phone is now on the EVA-L09C432B136 firmware. To test that the firmware is working as intended, go into the phone settings and go into Updater, updater should pick up the B182 firmware and you should be able to update it to B182 without an issue.
UPDATE: A number of people has reported that they are getting the B166 update instead of B182, if this happes, do a wipe partition and a factory reset after updating to B166. When you get back in, you should be able to update to B182 via Updater in the Settings menu. If this method does not work, you can manually update to B182 by following the steps here: http://www.carbontesla.com/2016/11/download-huawei-p9-b182-marshmallow-update-europe/
6. After your phone has rebooted and you are on the B182 firmware, you need to now update the firmware to B361 via Huawei Updater 2.0 using this guide: https://forum.xda-developers.com/showpost.php?p=70594380&postcount=2.
After all that is done, you should now have a debranded UK C432 P9 running EMUI 5.0.
Special thanks to @paulobrien, @somboons and @KrAzYtHeBoY for their guide, tools, files and video to make this update possible.
Props to you sir. I will try this when I get back. I don't have any doubts now after reading this guide.

Its very likely that debranding will void your warranty since you will need to unlock the bootloader and flash a firmware that is not the same as your original model.

Thanks for the guide. I've recently been battling away trying to go from C34 to C636 - still never got to the bottom of it.
Is that a typo in your post for your original model number - C43? Or did you come from Optus AU C34?
Either way - have you had any network issues in Australia with the new firmware?
Cheers.

Yep, its a typo, thanks for pointing it out. I have no issues what so ever, everything works perfectly fine and there has been no drop in cellular reception, wifi reception, GPS accuracy and etc. Apart from the build saying L09C432, you wouldnt be able to tell the difference.

Legend. Appreciate the reply - it was tough to find experienced Aussies on the same starting build/carrier.
Now I just wish I hadn't wasted the time going for the Asia Pacific variant!
Will get stuck into it this evening.
Thanks!
Great guide! Reading through it seems easier for it to be managed through hisuite/windows but I have a big issue. For some reason my computer won't recognize my phone! I installed the beta and am on build number EMUI-A168-L09C900B040SP11-log and since doing this stupid move I have been unable to connect to a computer nor install other builds or rollbacks directly on the device so I just feel like smashing it and claiming the insurance. Is there any advise that could be offered to maybe force a firmware upgrade?

I cant promise you that the guide I put together will work for you. If its a Nougat beta firmware then you would be technically doing a rollback to MM. Just a bit of a warning, a lot of people who try to roll back to MM, usually encounter problems, annoying problems. Unfortunately, I dont have much experience with this phone or how Huawei does things so I cant help you much. If I am in your shoes, I wouldn't attempt to debrand and flash Nougat using this guide.

Hi z-blade I flashed B136 but it didn't put icons and themes back .. I flashed B182 and STILL didn't put icons and themes back

I got theme and icon on mine but it may have came through when I flash B361.

It may be un-necessary to flash B166 if flashing B361 give you themes and icons.
If someone could double check on this when following this guide and report in, that would be great. I am not willing to test it out by rolling back to mushmellow.

Are you on an unbranded device?
If so, the official Huawei support page offers a rollback package if you updated to the Nougat beta.
Make sure you go to the page specific to your country.

Broken themes/icons seem to be caused by missing assets in the /CUST/ partition. I managed to get around it on my broken C900 firmware by separately flashing the /hw/normal/ package specific to the build. These can be found in the filelist.xml in the [WAREHOUSE] post - but you need to change the URL manually to grab the file.
SmartPhonesFan said:
So B361 will? Didn't know that.. Didn't want to risk it it took ages to download.. I had 3 folders in B136 but I flashed it via dial pad options.. Not 3btn..maybe if I would flash via 3btn it will give it back then and I wouldn't need B166..
Cannot be bothered.. It's done now..
Nougat best..
Click to expand...
Click to collapse
It makes no difference if you use the 3 button method or via the dial menu, both does exactly the same thing. I am only assuming that Themes could be installed when I flashed B361, I was not paying attention to the apps that was installed but I think this may be the case because I believe the Theme app was updated for EMUI 5.0, again all assumptions here.
Can I jump directly from b136 to b361?
Thanks in advance.

I've followed the guide as far as step 5. When I got there, I ended up getting an update for L09C432B166 which installed fine, but I'm not getting the B182 update. Anyone else run into an issue like this?

No you cant, you need to get to B182 before flashing B361.

Try wiping partition and a factory rest and see if you get the B182 update. If not, you can download the B182 update and flash it via dload but if that does not work, you can try doing it via the Hisuite and Updater method.

Can I Try Android O?

Sorry if this is a dumb question but I am not clear after reading several threads, and I've been out of the custom ROM and root game for 6 months or so.
I'm currently on the March version of PureNexus. Unlocked, rooted, etc. I kind of want to try out stock Android O. Would this be simple? I can just back up my current setup in TWRP and then what?
Sorry, like I said, it has been 6 months and I don't want to screw up anything... Phone has been running great but I want the shiny new toy... ?
Would I just follow this thread, minus the suhide part (I don't care about that)?

yes. or go back to stock..
my best suggestion is to go back to stock and then either manually flash Oreo or enroll on android beta.

If I go back to stock, do I lose all my internal storage? I assume not? I can just flash an original image I made before beginning custom ROM world?

Possible to downgrade official to official?

More specifically... Is it possible to downgrade from Official Pie back to Official Oreo?
There is no fault with the Pie OS itself. It's all about various preferences that are no longer available with Pie, as I do not wish to root at this time. Pandora lockscreen controls, the use of Substratum, expanded volume controls, to name a few.

Yea, that didn't work. Someone else mentioned a rollback ROM that could be used, but I am having issues finding it. I'll keep searching, unless someone else has done this already and is willing to chime in on what needs to be done.
Thanks in advance to anyone who replies.
I had problem using the rollback package... Device had been encrypted and no PIN accepted. So i had to do a clean install.
If thats ok for you just follow the steps here and you are back on OOS 5.1.5

It's a security patch/encryption issue. I believe you have to format (not just wipe) data. Then you should be able to install the stock rom.
Note that everything on your phone will be wiped by this, so make sure you're backed up externally.
Thank you all for the replies so far. To clarify, I'm on stock Pie and want to roll back to stock Oreo.
Full wipe, etc. is perfectly fine by me, as long as it's possible.

Hydrogen os to OOS

Hello guys, i bought my oneplus 7 pro from china and it comes with hydrogen os and i am trying to get rid of it.
I already tried to download the official package from OnePlus website and i tried to flash it using the recovery but it gives a pop up saying that i can't downgrade.
could anyone suggest me a good way to switch to oxygen os ??
Thanks in advance!!
Probably it's because they listed a lower version there.
Head to https://forum.xda-developers.com/oneplus-7-pro/how-to/oneplus-7-pro-global-repo-oxygen-os-t3930585
Download the latest zip and use the local upgrade method.

Use fastboot mode : https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424
Will definitely work
convert it with the international firmware converter

I was checking the thread but i did not see anyone tried this method to change from hydrogen to oxygen, so i'm a bit confused whether to try it or not

Usually flashing the stock zip via the systems updater should work but i guess if it doesn't then download the fastboot version and try.

If you're on a newer version of hydrogen, you need to unlock bootloader to go to a lower version. Dont forget. But might be better to wait for the next update of OSS and then flash internally. To be safe. Im rather new with oneplus too

i already unlocked the bootloader, but i don't want to risk everything so i will just wait for the newer update.
I have a follow up question. I might be wrong at any step so please correct me if I am.
From what I remember, during first boot of android people are supposed to log into their google account. So if I end up flashing OOS by local update option, will they ask me to log into my google account? I'm still in China and I don't know if I can actually skip that step and keep using my phone (log into google accounts later on after I connect to my VPN).
I don't want to risk changing OS and not being able to use my phone until I leave China.

Yes you can, take out SIM and do not sign in to wifi and just skip it. BTW which VPN are you using? DM me please

So far I did not install OOS. My H2OS is too fresh and I still need to wait a bit for new OOS updates. However I'm getting 2nd one for my grandfather tomorrow and I'll check how it goes then.
Yes, I'm in TJ.

Finally, I managed to install OOS and it is amazing.
I am studying in Tianjin but I just left for my summer holiday.
