I need to rollback (Honor 8), HELP! - Honor 8 Questions & Answers

I have a seemingly stupid but still annoying problem. As many of you know Android 8 + EMUI 8 came out this summer and I have updated my Honor8. Everything works well, even better (especially with regard to the battery) apart from a problem, quite annoying. I have seen that everyone around complains about the same problem, so it is clear that both a build bug and not a local problem.
Basically ... the bluetooth link with the multimedia system of my car doesn't work as it should, while it worked well with the 7.0.
Tracknames, music infos disappears, sometimes it connects regularly, starting the music, sometimes nothing happens, sometimes the music passes from the car speakers to smartphone (!!)... in short, manage the music in the car It has become a big problem!
I tried all possible options; reset pairing, reset bluetooth, clear cache, activate the developer options to control some low-level aspects of bluetooth, and finally installed Bluetooth Auto Connect which also has several advanced options. Nothing works. In the meantime an update of 8.0 has been released (mine is the buiold 521). The update came out in September ... maybe (MAYBE) this update fixes all bluetooth issues (but i don't have any detailed info about). Until today I have not received any updates and normally I check new version regularly every day. At this point I decided to return to Nougat!
And here the adventure begins!
I CANNOT IN ANY WAY do the downgrade.
What I tried:
- through HiSuite. The "back to previous version" option appears random (rarely); normally the program tells me "the system is up to date". Once appeared I tried to run the procedure, but after the decompression it gives me an error "error updating".
- by standard Rollback procedure. Using a microSD and putting the full version of Nougate in the dload folder. The installation starts but stops almost immediately with the same "update cannot be applied" error.
At this point I am desperate. I cannot update Oreo, I can't go back to Nougat and meanwhile the bluetooth still doesn't work with my car. Remember that before Oreo, everything worked very well!
What can I do? Can you help me?
Thank you

Region: EU
Model: FRD-L09
Build: 8.0.0.521 (C432)
Previous Build: don't remember. It was Nougat, and I've upgraded around the first week of September. From that day I haven't received/applied any patch, because nothing appears until now.
This morning I've tried again with HiSuite. As usual it says I'm running the latest version and it doesn't offer any downgrade option .

The more you know...

Finally I've decide to try updating to 8.0.0.562. After a month of tries, fails (damn Huawei and his stupid update system), errors and a lot of other stupid things, I was finally able to update my Honor hoping the latest version will fix all the problems. It was a enormous waste of time (searching around internet)... but in the end I found a method described here: https://forum.xda-developers.com/huawei-p20-pro/help/p20-pro-bricked-t3868085#4And if you go ahead you should find the correct firmware link (on a Russian site). Although, IMHO, failing with the classic method was due to the impossibility or some bugs in the update system, to unpack the update files on sdcard. So the solution seems to be to leave both the zip and the unpacked folder.The problems with bluetooth remain, but I hope that now there is not to be crazy applying next updates. ATTENTION: the method above is NOT valid for rollback! If you try, you'll brick your Honor.
And finally I've taken an important decision... for me this is the last Huawei/honor device. Next time I'll go to another brand, with a serious update system.

i rebranded my FRD-L19C900B141 to FRD-L19 with the help of re branding guide. i was then able to receive update of 1.3 GB which was apparently a mistake to do. i updated , it went smoothly but then now i'm missing Update Option and feature like smart key. i tried to flash recovery now, and it says remote command cannot be executed. i have frp and phone both unlocked and fastboot and adb both are detecting the device. Please Help

yes , U did a mistake after re-brand you had to receive the 2.2 GB update , this occurs because you didn't dload the official firmware of EMUI 4.1 after re-brand .and currently your build number will be in NRDM test keys . you wont receive any update , lacks of lot of feature , phone hangs a lot and drains .
So, do a thing just rollback to mash-mellow EMUI 4.1 FRD-L19C432B131 and from there make sure you are getting the update more than 2 GB ,if not just dload again the official firmware of B131 and again reset and see this time you will definitely get the right package .
INSTALL and enjoy.

Well , the reason I was not able to flash again with error , remote command not allowed was somehow the phones bootloader was not unlocked when it was showing unlocked. So unlocked the bootloader again and flashed the recovery.
About all the features , I had to reset the firmware from with in the settings , it deleted the os. So then I went to recovery and flashed official FRD-L19C432B131 and then I got the update of 2.4 GB in update update app, 2.4 GB is the correct one, not the 1.4 or 3.4. after updating I'm quite happy now. :laugh:

Another device stuck on FRD-L09C432B394

First of all, sorry for both repeating the topic, and for my ignorance!
I have an Honor 8 which is stuck on FRD-L09C432B394 and Android security patch level: 5 August 2017. I have received at least 2 OTA updates since I purchased the device almost 2 years ago but not since September last year (2017)!
I’m in the UK, I did not do anything with the device since I purchased it, and using the latest HiSuite version (HiSuite 8.0.1.300_OVE), no updates available either!
I downloaded a ROM from // huawei - firmware com/ (Sorry, can’t post links!) which is holds the description:
Build: FRDL09C432B521 800521FRDL19C432B521 800521FRDL02C432B521 800521
Android: 8.x - Oreo
Emui: 8.0
Size: 1.38GB
When I unzip this file I only copied UPDATE.APP to dload on MicroSD card, when trying to update via *#*#2846579#*#*, it starts but then fails at 5%!
Now I did some research and it seems like there’s more files required to update, when I unzip the downloaded ROM I only get the following files though:
full_mainpkg.tag (1KB)
new_filecontext_system (27KB)
new_filecontext_vendor (49KB)
UPDATE.APP (2,920,857KB)
VERSION.mbn (1KB)
And one folder named META-INF containing a few files.
When I did some research it seems like the files required are:
1) update.zip
2) update_full_xxxx_yyyy.zip ("xxxx" and "yyyy" = depending from hardware model/region)
3) update_data_full_public.zip
Where do I get these from? Is it UPDATE.APP or update.zip?
What am I missing? And if anyone knows, why am I not getting the update via HiSuite?
Thank you in advance!

I'm not sure if you mean flash via HiSuite as in downloading the Oreo ROM then use HiSuite to install it? Or just use HiSuite to check for updates and let it install it?
I do have the latest version of HiSuite (8.0.1.300_OVE) installed. Checking for updates through the software says that I've got the latest official version

You Sir are a genius! :good::good:
I didn’t have the time to try it last week but I just did and miraculously your 2 Update.app files have worked and flashed my device to B399!
Immediately after I got an OTA update to B404! But stuck there unfortunately! No updates available OTA nor on HiSuite after B404! Also trying to instal B407 via dload keeps failing at 5% every time! I read in your thread saying you haven’t done anything to the B399 file? Just deleted ‘Other files’ and rezipped? It worked anyway! Would be great if you could advise me on how to do it for a B407 or B521! If not, you’re still a genius!
Stuck on B404 now! An upgrade from B394, but wouldn’t mind moving up the line a bit!

I’m not sure what do you mean? Do I need to expect a bit of patience to get B406/7? I don’t have any patience left, I've had enough with Huawei
I’ve downloaded about 6 different firmware files from B405 to B521, I always tried the FullOTA-MF files first, then OTA-MF, all keeps failing at 5% but I ALWAYS get the ‘Software install failed’ message at 5% every time I try the SD Card\dload\UPDATE.APP method Are the firmware files I’m downloading corrupt? Your files did work so I don't think it's anything to do with my phone, but your files are the only ones that worked! I can't get my head around it

You first have to check if installation of each firmware is approved using Firmware Finder app. If it says it's not approved, it will fail at 5%, so there is no point downloading them
For me on my L09-C432, 406 was approved but was not displayed in system update app, I had to use Firmware Finder proxy to send it to system update app. Then I got 407, and could update to Oreo using hisuite on PC.
This method will fail on newer versions, but if 406 is approved for you and not displayed in system update app you can try it.

That’s what’s frustrating me, all the firmware files I’ve downloaded are approved for my device Or so does Firmware Finder app says! Yet they all fail to install at 5%!
Proxy method doesn’t work on B404, or at least not working for me So nothing is working now
I’ve had enough with this phone, just to avoid smashing it into a wall next time it drives me crazy, I’m looking to get another phone, Xiaomi Mi A2 might be the one. Still looking though
Successful update
Frustrated as I was I decided to try one last time and I’m running Oreo now
Trick is to use the official Honor rollback package from Android 7.0 to Android 6.0 (B131 in UK), let it preform OTA update back to Android 7 (B380 if I remember correctly) then use Firmware Finder application's in-app proxy to let the phone do the update at this stage! And it worked!
It downloaded the ROM files then when download completed it said the package has changed and requested to download again! I downloaded that and it started installation! Everything went well during installation but at the end it said it has failed because it could not find the update package I thought it failed and restarted the device only to find it running Android 8 and EMUI 8! Full reset and all working flawlessly
HiSuite acknowledges the update and offers to rollback to B407 if you’re having problems! Please note that I was stuck on B394! So even rolling back would be an upgrade
I’ve tested different apps, NFC (I never use it for contactless payments though so can’t confirm that, but I can’t see why it wouldn’t work) Also GPS and everything’s working just fine! Only issue is/was battery draining but that’s due to the auto launch in battery settings! I changed some of the application settings into manual launch and all great now!
Thank you for all those who helped :good: And hopefully this might help some of the frustrated Honor 8 users like myself! And hopefully won’t be stuck on B521 now!

Sorry for the possibly stupid question, but how did you find/apply the rollback package? Was it through firmware finder or is there some other way?

No such thing as stupid question! We all need to start somewhere
Finding the rollback package is via the official Honor support website for (Preferably) the country where you purchased your handset from. Or if it was EU, any EU country.
Rollback process will be executed by downloading and unzipping 2 files, the Honor 8_Rollback Package_FRD-L09_from Android 7.0 EMUI 5.0 to Android 6.0 EMUI 4.1_C900B300 (Around 75 MB in size) and the Honor 8_Firmware_FRD-L09_Android 6.0_EMUI 4.1_CXYZB131 (Around 1.75GB in size).
Next you should have a MicroSD Card installed, formatted, and create a folder on root called dload.
Then Unzip the files you downloaded, will get you 2 Update.app files, copy the first one (From C900B300) to the dload folder, switch phone off, press Volume-, Volume+ and the Power button and don’t let go till system starts updating, this one won’t take long.
When finished, format you MicroSD Card, create dload folder again, then copy the second Update.app file (From CXYZB131) into the folder, same button combination to update. This update will take longer.
When finished, try Firmware Finder app immediately if you can and use the in-app proxy method to let your phone do the update, if it didn't work, let the phone do OTA update but don’t let it update too many times because Firmware Finder doesn’t work with newer System Update apps.
Hope that helps. And good luck :good:

Thanks for the post, finally got some time where I could try this out and i'm now upgraded to 8.0 from the B394 I was previously stuck on.
I noticed a huge lag when first running 8.0 but it seems to have settled.
For me everything seems to be running just fine, all my apps works, all hardware works and, as far as I can see in 0.5 days use the phone runs it all about as good as it did on 7.0 after the initial lag that is

if you have unlocked bootloader, it easy to downgrade with NOST not OST LA.
just power off your phone, open up nost and plug usb to your phone, select firmware and flash.
but if you have locked bootloader, i dont know maybe downgrade with december 2017 update or else.

i have ta-1021 too, but mine has no problem like you.
if you want to downgrade, i have done downgrade too. because i installed beta pie and must downgrade to get official update. but my phone has unlocked bootloader which i get from site called technomezzo or what i forgot, buy bootloader unlocker service for $ 5. Then i get nost from hicary calix thread and nougat rom.

To many threads, what are the steps to change the original OS ?

Hello all,
I have read so many threads, and finally I'm still not sure to have the right method.
My current config has no more memory to update apps so I need to do something ! Here are the details :
Huawei P8 Lite 2017 (PRA-LX1)
build : 8.0.0.402 (C432patch01)
EMUI : 8.0.0
Android : 8.0.0
After reading several threads, here are my questions :
1. I have to use DC Unlocker --> is it always mandatory ?
2. Which TWRP do I have to use ? (link please, I'm completely lost, an still doesn't know which one to download ! :angel: )
3. LineageOS 15.1 seems to be the best choice (battery stamina), does it work perfectly ? (GPS, camera...)
4. What about Treble Project ? I still doesn't understand it is a better idea, how to install it, which ROM to use...
Thanks for all of your replies !
Hello,
DC-Unlocker is mandatory if your bootloader is locked. Recently, TWRP went official on P8 Lite 2017 devices. You can grab it from the official TWRP website (can't post links as I am a new user, search for 'prague' in the device list). I am using LineageOS 15.1 on my device and it's working flawlessly.
I use chimera to unlock bootloader.
But every custom to a have to flash isn't work. Boot loop or other issuses, like "device is uncertificated" so any google apps don't work.
Do i need to decrypt memory? To flash corectly custom rom.
Finally i have only root, and clean all brand apps.

Decrypt in which case? If everything works there is no need to decrypt.

After reading several threads, here are my questions :
1. I have to use DC Unlocker --> is it always mandatory ?
2. Which TWRP do I have to use ? (link please, I'm completely lost, an still doesn't know which one to download ! :angel: )
3. LineageOS 15.1 seems to be the best choice (battery stamina), does it work perfectly ? (GPS, camera...)
4. What about Treble Project ? I still doesn't understand it is a better idea, how to install it, which ROM to use...
Thanks for all of your replies !

1. Download DC Unlocker from GPlay, buy credits (it will send you username and password to your email)
2. Download DC Unlocker to your pc, in phone allow ADB debuging and HDB
3. Type into call app '*#*#2846579#*#*', tap on 'Background settings', next on 'USB Ports Settings' and select 'Manufacture mode'.
4. Plug your phone to PC and click on 'Detect device' and allow all stuff that will pop up on your phone.
5. Click on 'Server' tab (we are still on PC) and enter username and password you've got from app and 'Check login'.
6. Click on 'Unlocking' tab and choose 'Unlock bootloader code'. And your code should popup in text log.
7. Let's move to your phone, go to settings -> developer settings -> Enable OEM unlocking, enter your password.
8. Power off your phone and when it vibrate push Vol - and Power button at same time.
8. Plug it back to your PC and start Command prompt, enter 'fasboot oem unlock 00112233445566778899' (use your code).
9. Now just accept unlocking and formating all your data on the phone.
10. Download TWRP and let's flash it using command 'fastboot flash recovery_ramdisk twrp.img' (if your command prompt is in for example C:\Users\Pepege just cd to your Downloads directory where is downloaded .img file)
11. If it's succesfull just type 'fastboot reboot' and keep holding volume up, if eRecovery pops up click on reboot and this time hold volume up and down (idk why but sometimes works this and sometimes this combo)
12. If you are in TWRP just format DATA, CACHE and Dalvik Cache partition, make backup (if you wanna) and now flash whatever you wanna. LOS, AOSP, it's on you.
Also if you wanna LOCK (not relock) your device, download HuRuUpdater, download oldest version of Android for your model and region (C432 in this case) and flash it, after you reboot from recovery go to bootloader (fastboot mode) and type on your pc 'fastboot oem relock 00112233445566778899' then 'fastboot reboot' now do first setup, go to developer options, disable 'Enable OEM unlock', format data again (to be safe) and you are ready to go, after updating to oreo relock status should change to locked.
EDIT: Adding random Youtube video just in case https://www.youtube.com/watch?v=pclEmwt5C84
EDIT2: Project treble is simply stuff splitting system from vendor, it's on every device runing on oreo or better, more here https://www.xda-developers.com/goog...ze-android-so-oems-can-update-devices-faster/
Also for me best ROM are AOSP 10 and LOS 17.1
No custom rom wanted to boot. The method on this page will not work. All that's left for me is to decrypt the phone's memory. but then knowing that the weekend was over and I needed a phone call on Monday, I just let go.
@DunoCZ
What a great post, thank you so much !!!
Some people have reported more battery consumption on Lineage 16 and 17, compared to 15. Did you test all of these ROM ? Are there people here who have some feedback ?
@flgmnft
If I unterstand well, I need to extract fstab file from the ROM archive in order to remove the encryption : can you confirm or explain me what to do ?
@ilakhnon
It seems you don't have the encryption problem, what is your opinion about it ? did you edit the ROM fstab file ? other ?

Here you go guys, no need to edit it on your own
hummmmm.... bad news : my phone is not detected by DC Unlocker !
I should have tried before buying the license, but it doesn't matter.
But don't you find it strange ?
oh... I didn't read it correctly, the P8 Lite 2017 is not supported, only the P8 Lite (that was my mistake).
But I wonder if I really need it, because I bought it "sim unlocked", what do you think about it ?
EDIT : in other words, how can I know if I can erase the original bootloader ? (adb method)

Then try using hisuite to downgrade to nougat, but after unlocking upgrade to oreo to have treble enabled.
I'm waiting for an answer from DC unlocker's developper, and I will test this solution if I don't have another choice.
(I don't know if it is easy to downgrade with HiSuite, I've never used it, I will see that later).
Thank you for your help.

Hello @DunoCZ,
I was thinking about this post... I won't need to unlock the bootloader if I downgade to Nougat ?
Is there a topic talking about it ?
EDIT : Sorry, I didn't read correctly your post. Unlocking will probably be mandatory, so it doesn't change anything for me.

There's no problem unlocking 2017 with DC Unlocker which I did two days ago.
Install HiSuite and run it once to be sure you got proper drivers and make sure you put USB into manufacture mode.

I had the same issue, and contacted dc_unlocker's developer. Basically, the software can read the bootloader unlock password if it just discoverer the phone's port, even if does not seem to recognize the phone. I had to go ahead an got the code, for 4 credits/€
I'm also interested in knowing what is the best overall ROM these days in terms of compatibility and battery consumption!
Hello all,
Sorry for my silence, I had to go back to work, and after a few days I was seriously ill. I begin to recover some energy, it's not great, but enough to come back here... and because my phone, stiill with the original system, becomes really too slooooooooooooow !
@buteo : Do you confirm me I can go further with DC-unlocker software, in order to unlock the bootloader without any risk ?
@All :
As @Natural_High asked, which ROM is currently the best choice ?
Thanks for your help !

You can use DC-unlocker, it's safe. I used it myself a couple of months ago too.
Regarding the ROM, I haven't tried any Android 10 or 9 ROMs. From what I've seen, people say it's still a bit too buggy, so I went for LineageOS 15.1 and it worked fine. I did some tests, since I don't use it as my daily driver, but eveything seemed to work fine! anyway, feel free to try some of the newer ROMs and let us know your opinion
Thank you very much for your answer !
Lineage 15.1 was my preferred choice, I think I will use it.
I hope I won't have any issues, since I really need my phone...
Let's go for backup...

Question Cant Install a Systemupdate

I own a Rog Phone 5s (ZS676KS) since one week and tried to install TWRP without success. The result was a bricked phone and stressful days with no prospect of a solution. In this forum I found the following tutorial and completed it successfully
Repair ROG Phone 5S through edl firmware, no need to unlock Bootloader to modify COUNTRY CN to WW
Success is disgusted by some people, and will not share any files for free in the future.
forum.xda-developers.com
The update via the settings does not work, no update is found. So I downloaded the latest firmware from Asus and saved it in the internal memory. After restarting the phone I get a message that a system update is available, but it ends in an error message. I have tried the same with the previous firmware versions, but without success.
I would be very happy if someone has a solution to this problem.
You need to update the phone incrementally. You cant just go from the oldest version to the newest version through OTA updates....
Baby steps.
So i have to Update the next Version after the one i have and so on ?
