FRD-L09/L19 Rollback easy way - Honor 8 Guides, News, & Discussion

Hi
After searching both xda and official huawei site i finally found the rollback package for FRD-L09 and FRD-L19.
Method is:
1. Download rollback package (73,32 mb) and firmware (1,75gb) from: http://www.hihonor.com/uk/support/search-result/index.html?keywords=Honor 8#filter-section
2. Unzip rollback package and copy dload folder and Update.app to phone (dload/update.app)
Turn off phone, wait 10 sec.. Turn on phone by PRESSING BOTH (UP AND DOWN) VOLUME KEYS AND POWER KEY until emui screen, then release. The update installs automatically.
3. Delete "old/small" update.app from dload folder on phone
4. Unzip firmware and copy the update.app to dload folder on phone
Turn off phone, wait 10 sec.. Turn on by phone PRESSING BOTH (UP AND DOWN) VOLUME KEYS AND POWER KEY until emui screen, then release. The update installs automatically.
Now you have latest official Android 6.0

thank's
thank you, tomorrow morning i try

Did as you mentioned, but when I want to go back to MM the Updater says that the Package isn't available and stops at 12%. Could u pls help me.

I can confirm this works 100%. Followed the steps and I was back to Android 6. After setting up the phone I downloaded the OTA-update to 7.0. No problems at all, thank you very much for this small but very useful guide!!!

Hi guys,
I'm looking for a rollback method for the Asian model (FRD-L09C636) because a rollback package for this version doesn't seem to exist.
Has anyone tried to flash the MM firmware directly without the rollback package?
Thanks

I was able to downgrade my Malaysia version Honor 8 Nougat (FRD-L09C636B380) back to Marshmallow (FRD-L09C636B130) according to this thread:
https://forum.xda-developers.com/showpost.php?p=70863098&postcount=6
The rollback package is probably usable for all FRD-L09 as I have done the downgrading.

This worked fine, thx very much

Greatbro.

ANy way to re-lock to re-lock the bootloader?

Via fastboot or after downgrade

Probably downgrade. Looks like my camera hardware has died, fails on all custom roms and on restored emui5. So I need to return it.

Rommco05 said:
So install stock firmware and you will see if camera works. Which is your model?
Click to expand...

Yes, that's what I did, I had a full TWRP backup of all partitions - restored them all, rebooted fine into the phone, but the camera had just disappeared, like it had been uninstalled. Used gallery to get to camera, and it fails to open.
FR-D09

Rommco05 said:
aha, that's because u make restore via twrp. I have same issue, u must install original full firmware

How did you install original firmware?
Did you lose TWRP etc? Have you fixed your camera? Are you now able to reflash custom ROMS again?
(Sorry for lots of questions)

Oooh.. After a bit of a wait, I'm back up and running!
Now to rattle though setup and test the camera.

OK, we're back up and running, EMUI 5.0, camera working.
If I could find a way to disable the batterch charging light, I'd happily stay on stock!
Thanks for your help, Rommco05

Tried them all! Cant get Lightflow to control the LED at all, Led Manager controls notifications, but doesn't turn off charging LED.

Because it annoys me next to my bed, and if I'm in the car, and it's in the holder, I don;t want the led on all the time. LED=notification, not charging.

Hi,
on KIWI-L22 (Indian)
I had enrolled for beta program previously, so installed b130 and updated to 6.0 MM beta. I didnt like it much, so I switched back to CM 13.0.
As Official MM 6.0 is out now, so I wanted to switch to stock.
Following the procedure mentioned in OP, I downloaded L22-B130 and tried to restore stock but it failed mentioning "wrong version".
then I downloaded the L22-B320 version
http://www.hihonor.com/in/support/details/?DOC_ID=83346
and follow the same procedure. "voila" I returned to stock MM 6.0.
My whole point in saying all this is once upgraded to MM, then you have to use the MM "update.app".
Many thanks to Cosmodroid for this post.

[RELEASE] B190 OTA update for Europe (PLK-L01)

PLK-L01C432B190 (for B180): http://update.hicloud.com:8180/TDS/data/files/p3/s15/G939/g104/v51796/f1/full/update.zip
Just put the .zip file in your dload folder and do local update.
This update fixes issues related to icons and input methods and improves system security with the latest Google security patches. [Fixes] Fixed an issue where the Google input method can't be used when the system language is set to Serbian. Fixed an issue where the icon for the calendar downloaded from the Google Play Store and system calendar icon are the same. [Optimizations] Deleted the Huawei browser (with the Google browser remaining unchanged) for a better user experience. All user data from the Huawei browser, except for bookmarks, will be deleted. Bookmarks will be imported to the Google Chrome after you update your device. Improved device security with the latest Google security patches. Deleted quick sharing of application installation packages and images to ensure their legal use. [Update notes] 1. Before the update, make sure your phone has not been rooted. If you experience any issues during the update, please go to http://consumer.huawei.com/ or visit an authorized service center for assistance. 2. This update will not erase your personal data, but we recommend that you back up any important data before updating.

Hello,
Did you tried it ? 'Cause except for the security patch, i dont' think this update worth it, am i right ?
I think people who were in that version didn't got any update to B37x.
To my (limited) knowledge B180>B370 excluding betas.
in my case failed at 9% and I do not want to reset phone... staying at b180

Yes, the screenshot taken from my phone
@zinko_pt I got B371 update notification 1.18 GB in size.
@Ing.King really strange, i did it without any issue.
By the way guys, I just released it. It's up to you, updating or not..
We who had only B371 couldn't either update. Where and when will we get B30?

Really soo weird, I installed it at once without facing any problem.
It doesn't need a clean B180 rom because I installed it over my usual rom. It wasn't clean.
Something must be wrong in somewhere... but where?
Back here again..
No good news, tried to instal via sd, same issue, fail at 6%
But, but, but there might be a reason, i flashed the sdk21 of xposed, and idk how to remove it.. maybe this is the cause of it....
When you installed, you had to : unroot & put the recovery back ? Or you where "clean"
I'll try tomorrow, with a rest head

Oh, when I was saying "not clean" I meant installed apps and my all data

Hi,
Hmmm so maybe the xposed package.rar i've flashed made this error
Well, i'll try when i receive the H8
Or maybe i had to put the recovery of B100 instead of B180 :/
Edit 1 : When i check the local.prop, there is "ro.dual.sim.phone=false" or the PLK-L01 is a dual sim, so i don't understand ^^
Edit 2 : Flash with TWRP =
MD5's missing
coming from B180 stock /rooted /xposed.....
1.) i flashed all possible partitions i had extracted (HuaweiExtractor) from B180. (system; cust; boot; recovery)
2.) reboot
3.) i flashed full rom B180 from folder dload (vol up&down&power) to be sure to get really all parts of firmware!
4.) reboot
5.) local update b190.zip from folder dload
6.) reboot
7.) i flashed twrp rc3 with fastboot to recovery partition
8.) had rooted and installed xposed now
all works as expected! Now i am on B190.
at least i had to install some modifications to system again and recover my data partition (twrp)
all in all nearly 1 hour hard work!

Hi,
In fact you just cleaned up your B180 in order to instal the 190 ?
The "real" B180
Pure stock if i could say ? Sure, it will work, but i tried to install it without getting back to stock^^
uff 1 hour to achieve upgrade... pity that I have to do factory reset to make upgrade to b190, no root no open bootloader no changes to firmware despite all this I cannot upgrade normal way... very sad, bad job honor(huawei)
because i had made a backup of my apps and data with the HUAWEI backup app (update to version from PlayStore is necessary!) recovery was easy! Had to remove some blood ware and unused apps only!
then reinstalled PMplus; managed autostart and apps they should stay on if screen is off.
reinstalled my google account
all in all a little bit more than 1 hour like i told you
now i am on b190 rooted; xposed and xprivacy activ on; and of curse Viper4Android for better sound.
real easy!

How did you update it? if you were rooted then you have to flash img files manually first before doing a three button update.

Yes, as B371 is the latest one so they will push B371 only, now there are no incrementals. But I have put up a thread here, maybe sometime later I'll post the OTAs too.

camera doesnt work after update from mm to Nougat

Hi,
I have a p9 lite l21 and updated to android 7 and emui 5 fromThis
after update my camera dosent work so u thought install camera app but it also dose'nt work!!!!!
so downgrade to mm and tested,it's ok ,then update to n but no improvment.
what can i do to fix this?
It's a known issue. Several people, including myself have faced this one, together with the "app incompatible" bug when updating apps.
Supposed to be fixed in Revolution Nougat RC3, however that is not yet out for the general public.
For now, these two issues are keeping me on stock MM.
My camera didn't work too. Try to reflash Nougat again and if that doesn't work go back to MM, then again on Nougat and it will work.

Rollback to Stock Firmware - European Version

Hi,
I played a bit around with my Huawei P9 Lite, but I forgot to save my initial settings (originally it's a branded phone by 3 Austria). - Yes, my bad.
Now I'd like to go to back to the original firmware. I realised that I have firmware VNS-L21C900B161. - But my phone used to have C432, not C900.
What does C900 mean? Do I still get updates? How do I get a C432 firmware?
Sorry for those many questions, but I am desparate. I just want the correct Version for Europe (unbranded). - Also to get the update to Android Nougat.
Any help is appreciated.
Seth01
You must flash oeminfo C432 and then flash update.app...there are good tutorial in youtb.....
It worked, but... :/
Hi
thank you so much for your help. Now I have the European OEM C432 Version.
But if I (re)boot my smartphone now, it says , "Your device has failed verification and may not work properly." - But it does work properly and it also boots normally then.
How do I get rid of this message?
Greetings,
Seth

I am actually afraid to reflash. Will it then not become OEM version C900 again?
Can I flash via SD-Card with the dload folder, or do I need a tool? (I have downloaded and used the "VNS-L21-L22-L31 Toolkit.exe".)
Seth
Did you make factory reset before boot??
Yes, i did. And In the meantime the message is gone. So everything's fine so far.
But my bootloader is still open.
Any idea how to close? The message on reboot that the device can't be trusted, is rather annoying.
Seth
You got to relock.use the toolkit.....for me after downgrade that warning message about bootloader unlock is gone.but in fastboot my phone is unlocked...
Yeah, I'll try tomorrow. I tried to lock with the tool, but it crashed when I tried to.
Thank you to all of you for your help!

Nope. It will not become because you will flash the c432 version. That message you get is because you unlocked your bl. A simple relock or firmware flash via dload will solve your problem.

Hello guys,
I own a L21C342B160.
I would like to upgrade to Nougat since i've read its stable.
How safe is to do that ? I would not like to revert to MM due to something going wrong.
Thanks you !

It just says, that version is incompatible with current b170 version.
Besides, tried upgrade through FF, but it does nothing even when I change proxy setings :/

Nope, it's 100% safe and u'll never get a bootloop, but it's safe to always make a backup before u make an update. Cu multa placere

It's a bug with that proxy setting... restart the phone and it will work
I am on VNS-L21C432B336 (beta) and i'm unable to install B370 via FF proxy. After downloading, it fails verification with error "failed to authenticate the package....will be deleted".
I can't post in the P9 Lite thread, so i am trying here, if someone can help me.
Do i need to downgrade to MM, B160? Cam i update to 370 via dload folder and 3 buttons method without downgrading?
I already tried rollback via this metod http://forum.xda-developers.com/huaw...vices-t3563955 and after 5% it gives the error "Software install failed! Incompatibility with current version. Please download the correct update package."
Do i have to do anything else before loading the rollback file onto the SD Card in the dload folder?

I used the exact rollback package to rollback from b371 incomplete build to b160 and worked great...
Is my phone supposed to be rooted, or have TWRP installed for the operation to be completed successfully?
I tried 2 times and it always fails at 5 % giving the error "Software install failed! Incompatibility with current version. Please download the correct update package."
The phone should be unrooted with stock recovery for this to work.
Did you try directly updating to b370 or 371 via 3 button method ? Not sure if this would work but this is what I would try to do if I we're you.

When i bought the phone, the bootloader has already been unlocked, and TWRP installed. I wanted a clean experience so i flashed the beta 336. TWRP is gone, so i belive is not rooted anymore. The message at startup still shows up that " your phone can't be trusted". So is the bootloader locked now? Can it even be relocked?

I don't know the answer. As far as i know flashing b336 should relock the bootloader and get back to stock recovery. In development topic there is a discussion about going back to stock. Maybe there you will find the way to get back to stock.
Don't try to flash b370 or b371 if you are unsure that the bootloader is locked. I will search more info on this and get back to you if i can find something.

I have read on the forum that is not possible to flash b370 directly from b336. If it bricks the phone, how will i flash another stock rom? I was planning to rollback to b160 and upgrade to b370 using the firmware finder and the stock updater. I might give it a try, flashing the B370 directly. Also, will i need 2 files, on the dload folder? The update.app and the big 1.94gb image? Thanks
Also, if huawei finally releases the B370 OTA. will i get the update automatically if i am on beta?

Nope
Still nothing changed
Almost lost the hope
Ff proxy doesn't work.
Three buttons method allso not a solution :/
Maybe its something wrong with my head, not with the phone
Helpful video
I was having difficulty figuring out how to use Firmware Finder when I upgraded to B360 on my VNS-L21. Then I found this video, and it worked perfectly.
Forgive me if this is old news, but it may help someone who is also having difficulty:
I am unable to post the YouTube URL as I am fairly new, but search for this title: "[How to] Using Firmware Finder by Team MT. Installing any firmware from Huawei update server."
I finally managed to find the courage to update. Went smoothly. I can confirm that Firmware Finder works, but be careful to download the right package. For B160 - B370 and B161 - B371. Both are 1.94 GB in size. Nougat is very nice and all features work as intended. Lets see the battery life now...
