Problem updating P8 Lite Single sim.

[khrystoff]

Hi, I recently bought this phone and its awesome but it has a problem, when I type sometimes it types 2 letters instead of one and its very uncomfortable... I've read on internet about this problem and apparently last versions like B194 (Only for Dual SIM) and Marshmallow 6.0 (B550/B551 Dual and Single Sim ) fixes this problem but here is the thing, I'm with the B181 version (ALE-L21C40B181) so im Single Sim and I wanna keep it that way. I tried to install the MM 6.0 551 for single version and it just simply doesn't work, I choose the option "Local Update" but when the phone restarts shows me the message "Install software failed"... I tried the vol+ + vol- + powerup button method but it stucks at 90% all the time and can't do anything...

Anyone can help me? I just can't update it.

PS: My bootloader is unlocked and I don't have any root!

Greetings!

So you must have one of these firmware to successful firmware upgrade

Uhm, I have the B181 and seems to be the latest update and I don't know what to do, what are my options?

Your phone is branded by Telefonica Spain. So you must debrand and use eusingle firmware like B171, B183....

For official update you can't have unlocked bootloader.
Also, you have to be on certain version to be able upgrade. Also make sure you have the correct file (C432 etc).

If you are on C40 firmware you can flash only C40,otherwise the update process will stop at 5% and fail. You can debrand your phone as well and then it will be easier with the updates.
