Can I flashed this from beta 12 with TWRP?

What steps should I follow to flash this ROM if I am coming from a custom ROM? I was on VertexOS with 4.0.3 firmware and using RENDER KERNEL. Do I just wipe system, data, and cache and then flash OOS and SuperSU?

i have flashed the full rom.zip on twrp . now when i boot into recovery, twrp is asking to enter password ?? what should i need to do ?? i guess phone is encrypted .. How can i get my files back ???

Can someone extract the gallery and camera app in oos and post it. Thanks

What version of TWRP that you are using? Mine is 3.0.4.1 and i have no issue on the encryption error. Try to flash the latest TWRP version to see if that can bypass the error message or not.

Google Drive link for OP3. anyone? Thank you.

I have also decrypted memory. How to upgrade to the new version without encrypting memory again (and loosing everything)?

Flashed stock recovery n also tried twrp recovery.. Nothing bypassed the encryption. Asked for password. Finally decided to wipe the internal storage.
Lost all my personal data n pics :crying:

Video installation guide? I may not want to have TWRP problems..

Just one simple question: Why are you all staying at 3.0.4-1, when official 3.1.0.0 is out, able to get the job done without any problem? Just asking.

Guide to install Nougat / Emui5 on BTV-DL09

Okay, managed to get Nougat and root for my BTV-DL09. Here is a fast forward tutorial how to do that.
I could only root it by using Magisk, Supersu (even the special emui5 ones) did not work for me.
Files:
ROM: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1224/g490/v78425/f1/full/update.zip (BTV-DL09C233B336)
Data: http://update.hicloud.com:8180/TDS/...full/dualcu/cn/update_data_full_dualcu_cn.zip
TWRP, make sure to use twrp_BTV-DL09_5_greatslon.img : https://androidfilehost.com/?fid=817550096634750327 (thanks to greatslon)
Root: https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
I came from version BTV-DL09C100B006, this is how I did it:
Bootloader must be unlocked, custom recovery installed (Do not install the one for EMUI5 yet, it won't boot).
Enter recovery by adb reboot recovery
Wipe, reboot recovery
Flash ROM + Data
Flash Magisk Root
Flash Recovery again (will be overwritten by the udate)
Reboot, Done.
Download playstore / vending APK from APKmirror: http://www.apkmirror.com/apk/google-inc/google-play-store/google-play-store-7-6-08-release/ and transfer it on the device.
There is an app called "Downloads" preinstalled (there is pretty much nothing on the tablet, not even a browser after flashing it), you can use that to open/install the play store APK and get things going.
Please make sure you know what you are doing and you know how to recover from a soft brick. I take no responsibility if anything goes wrong.
The version you should have now is BTV-DL09C233B336 with security update from February included.

Thank you very much, and how to downgrade ?

can someone upload a youtube video showing us the the new EMUI5 on this tablet, and give us an overview about the new features and performance?

Beware that:
1) this is a chinese ROM
2) Nougat version 7.0.0
3) if you don't like the downgrade process is difficult
4) if you want to downgrade have to find another ROM!!!

any idea to downgrade please

You need another ROM, FULL not OTA.
1) extract from the .APP the recovery (both) and boot images
https://forum.xda-developers.com/showthread.php?t=2433454
2) get a build.prop from the ROM you want to install
3) copy the build.prop in the /system folder, overwriting the original: now the old ROM will unlikely boot!
4) go in fastboot mode and flash recovery, recovery2 and boot images
5) copy the update.app in the dload folder
6) reboot and maintain pressed both volume keys to start recovery
7) if you are lucky the recovery will install the ROM.
Of course you will loose all your data (uhm, not even but... MAKE A BACKUP before!)
If you don't know well how to do ALL this don't even try!
If you have the original european LTE ROM please share it!!!

2) get a build.prop from the ROM you want to install

Hi nicolap8 even I followed the same steps as you suggested with the file links you shared and I am also NRD90M test-keys on my Mediapad BTV-DL09
installing Magisk first time gave me a fail message but second time it works like a charm. thanks
could you help, thanks

Switched to eu rom, updated to nougat.. unlocked bootloader and rooted with magisk
But using magisk caused the fingerprint sensor not to work at all and there is no settings for the FP in the settings menu.
Uninstalled magisk and the fingerprint worked again but obviously I lost root.
Flashing SuperSU didn't work gives an error in twrp no matter what version I try.
Any idea on how to root without compromising the fingerprint sensor?? :/

Worked for me, thx.
The fingerprint button doesn't work anymore.
Is there a way to activate it (without loosing root by uninstalling magisk)?
Kind regards

Thanks for your effort IacobIonut-DW, and it works great, but only if you decide to use Blu's Stock Marshmallow ROM.
The bad news is that the problem is still present if one goes beyond stock and try to install any other custom ROM like AEX or Resurrection Remix ROMs.
I think that most people here want to skip using the stock (while rooted) ROM and experiment with other ROMs like AEX and RR.
Any pointers would be welcomed!
In the meantime, I am on MM Stock, Rooted and debloated.

Try to use SPlus LP and MM Firmware

Quite honestly I've been swamped with other things and have not tried this yet.
So you're saying that you have AEX running (or other custom ROM) with your Blu Vivo XL without losing both IMEI?
I'll try it out later, but just checking in the meantime

It works very well and I was really surprised at the speed with which the operating system loads. Although surely much is because I have not installed the gapps yet.

Awesome to know!
But I'll have to ask which S Plus rom variant did you use? I found three different ones with different numbers. ?
Also what Custom ROM did you installed?
Thanks in advance!

Hmmm, even after trying all that's been said here, I simply can't keep the IMEI functions after flashing any custom ROM. I know my way around custom roms since the XDA days but this one is really getting on my nerves... U_U

Nevermind I have it working now!!!... With your feedback I was able to come up with a different path to get the firmware directory in place without corrupting the ROM.

Tutorial(downgrade8.1.0=>7.1.1)use nougat stok/custom-roms on Oreo BC-12 bootloader

Tutorial(downgrade8.1.0=>7.1.1)use nougat stok/custom-roms on Oreo BC-12 bootloader
This tutorial is for the users wich are not satisfied by Oreo 8.1.1 rom
Also can be used by users wich changed the touchscreen from some reazons
and on Oreo 8.1.1 this new touchscreen not work​
First got to Settings/System/Developer option and chec OEM-unlockin to be ENABLED!
for flashing twrp-recovery may be need to unlock the bootloader by code but it should work only with OEM-unlocking enabled
Downgrading with FASTBOOT!
1) Charge youre phone to at least 50-70%, better is 100%
2) Download the FILES necessary for downgrading
3) Reboot the phone in bootloader and connect to the pc
4) Opend the terminal and write "fastboot" or "mfastboot" depends by your instaled fastboot
5) Copy/Paste in terminal the lines writed in "fastboot-mfastboot.txt" atached to files
or write them one by one and press ENTER
WAIT 'till it finish
6) In bootloader screen, from buttons vol-up & vol-down navigate and set to "reboot recovery" and press Power
Phone should boot in TWRP-recovery!
Now you have to install a custom-rom or a stok-rom TWRP flashable with Install option
""for this use the instruction to install posted by the developer of each rom""

This tutorial is for the users wich are not satisfied by Oreo 8.1.1 rom
Also can be used by users wich changed the touchscreen from some reazons
and on Oreo 8.1.1 this new touchscreen not work​
First got to Settings/System/Developer option and chec OEM-unlockin to be ENABLED!
for flashing twrp-recovery may be need to unlock the bootloader by code but it should work only with OEM-unlocking enabled
Downgrading with FASTBOOT!
1) Charge youre phone to at least 50-70%, better is 100%
2) Download the FILES necessary for downgrading
3) Reboot the phone in bootloader and connect to the pc
4) Opend the terminal and write "fastboot" or "mfastboot" depends by your instaled fastboot
5) Copy/Paste in terminal the lines writed in "fastboot-mfastboot.txt" atached to files
or write them one by one and press ENTER
WAIT 'till it finish
6) In bootloader screen, from buttons vol-up & vol-down navigate and set to "reboot recovery" and press Power
Phone should boot in TWRP-recovery!
Now you have to install a custom-rom or a stok-rom TWRP flashable with Install option
""for this use the instruction to install posted by the developer of each rom""
Also you can RESTORE an older 7.1.1 backup made before update to OREO
Reboot and enjoy by nougat-7.1.1 rom on oreo-8.1.0 bootloader

Also, can I flash Stock Nougat (using fastboot) after this? And is there any chance of my device being hardbricked?

No! you cant flash a full nougat rom with fastboot.
Bootloader cant be downgraded!
for hardbricked phones you have first to boot it using the sdcard img.
then when you get bootloader working without sdcard, can use this tutorial

1. Oreo Battery drains considerably faster than 7.1. (But charges faster too)
2. Fingerprint unlocks slower than 7.1
3. Lags slightly when doing intensive tasks.

Now we need a maintainer for (a) Nougat rom(s)..

LOS14.1 has been updated:
NEW BUILD: https://www.androidfilehost.com/?fid...63190603848665
Change log: November 18 Security Update
NOTE: Like so many other users, I too updated my device with OREO and stuck with that. I haven't tried downgrading it because I don't want to end up with a hard-bricked device once again. Point here is the new build is not tested. So please take a TWRP backup before using this build. Don't forget to post me even if works fine.
Thanks,
KS

Thank you so much for your feedback, ShattrdChain! :good:
May I know what rom did you use for flashing with this method?
And do you know if bootloader needs to be unlocked in order to downgrade with this guide?

TWRP method doesn't work (bootloop), pls fix or delete.

Its works great.
You can also use fastboot to downgrade!

can the downgrade be done without the bootloader unlocked?

the methods don't work for xt1799-2!
