updater on my phone doesn't detect updates to B852
i know..
just do it manually..there should be no data loss or something (you have the option to do a backup)

This is B839. After installing it you'll get the option to do an OTA update to B852
This is official firmware so you don't need root nor bootloader unlocked.
Roll back to old version

Has anyone tried the full firmware?
I did the update all the way from B621 without losing data, so I'm on B839 beta update no problem.
I want to know If I can do this without losing data?

Is it the same as the beta? Is there any need to update?

Yes, local update dont delete your Data.
It says "first you should format your sd card"
Any way without formating sd card?
Is it still beta?
i got a error, i think it said (wrong cust number). i should do a vendor upgrade i guess?
"Step 3. Make sure that there is an UPDATE.APP under the Vendor\hw_eu\dload. Copy the Main package of dload in PC to dload of SD card."
but i can't open the update.app... need help
If you're already on B839 beta update, this update (full) keeps your data. Ta @87insane
No its still no beta....beta test ends

is there any reason why I should do this full update? I'm on beta B839 (OTA update from B830) and everything works great (first working lollipop on my phone). So I don't know if it worth to try this full update? Is there anything new or better compared to OTA beta B839?

Of course full firmware is better then OTA.
backup your data
make factory reset
force update the full firmware

I'm like you - I hate having to redo my whole phone.
If you're already on B839beta, local update of the full will not erase your data - is like doing an OTA except with the full UPDATE.APP
The difference is very little...it feels smother for me and the battery is better but that may just be from the cache wipe the update does.
I was not on b839 beta before...the data will not erase with b830 and b609 too.

hi everyone
i upgrade my phone from b158 to b839 and then update it to b852
how can i retrieve to b158?? i download the b158 full update pakage , copy it to dload and try force upgrade but it dosent work!
i dont want to root my phone
pls help me
thanks
hey,
you need to to a middlestep by flashing a transition pack (b800)..
after flashing this through local update you are able to flash a older firmware (like b609/621)..
to go down to b158 you have to flash again a transition pack (b603) through local update and then the b158..
you can find all information on this forum - by using the search..

there may have been a damage to your rom. I downloaded b852 from somewhere else installed it installed the rollback again and it worked. Actually I saw many changes after installing b852 again e.g. motion control worked properly or I had the swype keyboard. maybe they did some updates to the rom. be successful!
Now, for about 10 days that this full B852 rom was released, i have tested all 5.1.1 versions, even changing cust region for B853.
Now i can tell you finally we have full stable, smooth 5.1.1 lollipop for our P7
1/ Full B852
LINK: HUAWEI
General Version with vendor package: General Version
2/ ОТА B830->B852 Huawei p7 l10

3/ ОТА B839->B852 Huawei p7 l10

Enjoy your phones :laugh::silly:
Thanks! Trying out right now!
UPDATE: Damn! "Software update failed!"
Will look into ways to manually update.
SECOND UPDATE: My device was hacked a few times before and maybe that's why the update initially failed.
I managed to manually install it.
It's working just fine! The notification panel and the shutdown window look really nice with the blur effect.
Most importantly, battery life is better than 4.4.2

Thank you again!!
I did this update, before I was on b852 ota, after 2 days from the update all my pictures were erased, i don't know what is the reason, maybe the update is the reason. So be careful.

see this to recover your pictures:
Android Data Recovery
or use :
Deleted Phone Data Recovery APK
Undelete Master APK
DiskDigger Pro file recovery APK
Undeleter Root Users APK
This version is nice working fine here
Is it better, smoother, faster than B853?
thank for help pls help me T-T
- Use firmware finder https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder
- Search if the wanted firmware is available for your phone
- Root your phone if possible.
- install new firmware.

If you are on one of the latest versions (security patch after June 2018), this will probably be very difficult. Huawei included anti roll-back in the latest versions. With a locked bootloader you cannot install older firmware and with an unlocked bootloader you may brick your device. As far as I know the only option is the test point method, which requires opening your device.
