How to upgrade from balongc52b311 (Android 6 Single SIM) to Android 6 Dual SIM

Hi. I have new phone Huawei P8lite from T-mobile and I have version of FW balongc52b311 at now. This version is only SingleSIM. I need DualSim.
I tried to do downgraid (fail after 5%) Instal directly Android 6 to dual SIM (fail after 5%). In Update section I do not have update from local storage. I have to reboot with using all 3 buttons.
Please has someone manual for it. Which version I have to update at first? I do not want to damage bootloader (loop problem)
At now I have unlocked bootloader. And phone is ok.
Thanks Peter

do you see that little word? BALONG?
it's a bug, you can't upgrade due to that bug... you have to fix it.

Stuck with balong311 after updating from b188 to b550.
I tried to flash vendor from 049 without success. But i saw today that b049 is single sim. Think i should look for a dual sim vendor img and flash it?
Im really not in thhe mood for a downgrade...

Proxy method?

Better let someone else handle the updating, seeing as you're don't like reading too much.

Dude, don't be salty because getdroidtips isn't clear.
I managed to update btw, close this topic

Dude use Firmware Finder app and dns/vpn method
to try to force the upgrade ( try to use B361 FULL OTA-MF PV first ).
If all will take right direction, then use same method to update to
B502 (dual sim) or B503 (single sim) FULL OTA-MF version.
See the attachtments and good luck.

Dear,
huawei never planned to forward oreo official upgrade to p9 lite ( 2016 aka venus model ) users,
so do not waste your time looking for this, it simply doesn't exists...
B502 ( dual sim ) / B503 ( single sim ) are latest Nougat firmware.
Cheers

Firmware Finder is down bro, definitively. You can try to upgrade using dload method. Download Service ROM for dual SIM
and flash it, instructions can be found in ReleaseDoc folder. This process will erase all your data (and lock the bootloader again) !
I hope you have Dual SIM variant. If not, let me know.

Huawei p9 lite update problem

Hello,
this happened because you
choose that firmware...
you are very lucky you didn't bricked your device.
You could try to use Firmware Finder again
to revert back to your previous version,
but as i told, you could brick it,
that's your choice.
Another way is unlock the bootloader,
install a custom recovery (TWRP),
flash an OEMinfo file and your correct firmware.
It depends on the android version,
on the region (CUST) in which you live
or for which the firmware has been released
and if the device is single or dual sim.
Good luck dude !
P.S.: took a look and it seems
the link for Hassan's twrp download
is no longer available...
Maybe other twrps are still available,
but i'm pretty sure someone could
repost it for you...

I have tried to reinstall it to my previous version, but it didn't work.

No.
At least up to my knowledge, it is impossible to get the code without a PC (more precisely, you can unlock BL without PC only if you have the unlock code).

You can try flash it with Service ROM Download . Type VNS-L31, or VNS- .
Download correct firmware - EMUI version, Cxxx (the bracketed (Cxxx) is your device’s regional variant.
This number is very important in determining the correct firmware to download. Select your previous Cxxx, not current C00 ) and single/dual SIM (all firmwares that end with even numbers are for dual SIM, odd numbers are for single SIM).
Instructions can be found in 'ReleaseDoc' folder.
If you cannot unpack downloaded zip archive on PC, unpack it in the internal memory using this RAR apk.
Extracted 'dload' folder copy/transfer to the SD card. Good luck.

I forgot the last cxxx of the build number, but the model is l31 for sure, dual sim and comes with Android version 6.0, EMUI 4.1

There's no Service ROM for EMUI 4.1 , you have to flash UPDATE.APP file.

Any forced flash with wrong region will bring your phone to C900 (global) or will brick your phone.
