Hi, do you tested this? after this procedure i will receive the official OTA of Android 7.0 ?
Thanks!
one more thing, you put 3 download links, we have to flash the 3 in order ?
1) rollback package, then
2) Marshmallow Stock Rom, then
3) Marshmallow version: BLL-L23C605B120
that is the correct way?
thanks.
Number 2 and 3 are same files,
Yes its correct way,
Don’t worry, it’s safe
Waiting for your successful rollback
Hello, I have a problem. When I did the upgrade using the other post https://ministryofsolutions.com/2017/04/huawei-mate-9-lite-bll-l23-nougat-b342-update-emui-5latin-america.html I get a compilation number NRD90M test-keys. I don’t know how to fix it because I don’t know which is the data file you are saying. However, I try to install the rollback package and it doesn’t work. The compilation number still the same NRD90M test-keys. Please help me.
You need to read that page then you will definitely find data file download link
I have bll-l23 latín América
Hola la hice rollback con éxito, pero el detector de huellas no funciona y la compilacion es bll-l23C605B120-log
Y al parecer es una.versión de prueba beta.
Fingerprint not work
Compilación with -log
Beta versión?
no se puede hacer mas a partir de ahí. este tutorial no tuvo en cuenta ese detalle, falta instalar un segundo paquete que es el que arregla varias cosas y cambia la version, pero no tiene el update.app que necesita el método de la carpeta dload, tienes que esperar a que salga una versión completa o volver al 7.
Please download B100 full stock marshmallow from this link: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1277/g104/v66229/f1/full/update.zip
And let me know if it fixes your problem
Try this full stock marshmallow firmware B100 http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1277/g104/v66229/f1/full/update.zip
Ok, let me see, tnks

Hi,
Anyone could rollback to MM?
When I install build C900B300, my Mate restarts and seems it´s installed correctly, however, at the moment to confirm on settings, it keeps the same “test Keys” version.
If rollback package installed successfully, install marshmallow after that
Hi Mutahhar,
That´s the problem, for any reason, the rollback package is not installed succesfully, I follow all directions step by step, it seems everything is OK, after insert a sd card with dload folder and update inisde it, I made the 3 button process and the package runs 100%, it restarts, but any change it´s reflected, any idea ho to fix it and what´s is missing?
Thanks in advance for your support, I´m stuck in this two weeks ago!
i’m stuck in NRD90M test-keys after try to update to nougat
Install rollback package and then install marshmallow
install the version of the roolback with success but it does not let me enter in recovery mode or to install the update.zip
You should extract the marshmallow firmware and use update.app for installation
Gracias, me sirvió, aunque sea una versión beta va bien, hasta ahora ningún fallo detectado.
Muchas Gracias…. thank you very much
Very useful article !, really works as described. Went from “NRD90M test-keys” in the begining to the “BLL-L23C605B120-log” at the end of the process. Now i will see how to keep updating for newer version.
Will it be possible to update using Firmware Finder if installed for newer updates ?.
Yes you can upgrade, make sure you use dns method. Good luck
