If you're from B129, you can skip #1 and force update to B621. Just follow steps #2-#6.... Because I believe you have to update your cust to eu432 for you not to have problems like losing your keyboard, motion control, etc..

All the links of firmwares that you need are in this page (http://www.carbontesla.com/2015/10/download-ascend-p7-b830-android-5-1-1-lollipop-ota/ and look under Update Instructions) except for the vendor update, which I have included in my post.

You can check Cust on Settings->About Phone->Custom Version. Your cust version should be CUSTC432D001, or atleast starts with CUSTC432****.

Did you try to rollback first? Because I swear for 2 days I kept downgrading and upgrading again and again either to B830 or B832 to B839. However after so many times of trying, whenever i upgrade to lollipop, i would lose my keyboard, backup app, etc. I even almost gave up and thought of just going back to B832.

At first I tried to force downgrade to B609, after I rollback wth B800 ofcourse, but i couldn't find a vendor update for it, it would just give me the same problems. Then I decided to force downgrade with B621 then updated my vendor to eu432. I believe it's the most important part of the Lollipop update, to update your vendor to CUSTC432.

---------- Post added at 03:17 PM ---------- Previous post was at 02:55 PM ----------

Guys, the most important part of Upgrading to B839 is to update your VENDOR to CUSTC432 because it will give you all the functions that you need, or that's what I read atleast. If what I posted did not work for you, then you have to find a way to update your vendor somehow.

We may have the same phone, but some have updated or downgraded in different ways that may have affected it's updating process. You just have to find the right one for your P7.

By the way, I am so happy with this update. I can use Facebook and watch videos again. Everything seems to be working great! :D
[Huawei Ascend P7] Turdor:
Thank You sheenamoll!!!

I´m on B839 now, but before it was B129, so how to proceed?

Can´t find Custom Version - it´s just not existing in Settings->About Phone->Custom Version, also on another Huawei P8 Lite can´t find it too (
[Huawei Ascend P7] sheenamoll:
You're welcome. :) If you're on B839 now without the keyboard etc. Follow the steps from #1, you have to rollback with B800 first, then turn off your phone, hard update B621 (volume up + down + power button.)

For now I don't know why it doesn't show, because I haven't encountered that problem yet, but if ever I read something about that, I'll be sure to post it here too. :)

---------- Post added at 03:34 PM ---------- Previous post was at 03:23 PM ----------

Here are the links to the firmwares you need to update to B839:

B800

B621

Vendor CUSTC432

B623

B830

[Huawei Ascend P7] Turdor:
Do you think After updating vendor can I go directly from B621 -> B839

or

B621 -> B830... without B623 with this direct update (can´t post link, but it´s a link from carbontesla direct update to B830)

or you already tried all of that combinations and came to the magical mentioned above combination? :D
[Huawei Ascend P7] sheenamoll:
uhm... I didn't try that one because I was so exhausted from trying other processes and I just wanted to get it over with and be safe. haha! but I believe even on other threads it says b623 is really necessary.

My advise is to just include b623 in your update to be more safe and save time.
[Huawei Ascend P7] Turdor:
Yahooooo!

Keeyboard and Co is here! :D:D:D

Bloody CUST is defeated! :cowboy::silly::cowboy:

Here is my 2cents or how I did it lazy way with instructions from sheenamoll (:silly:Do it all on your own risk, same as me!:silly:):

1. Roll back with B800 (local update) (I believe you can skip it if you are previous to B621)

2. Forced B621 update (Downgrade), end up with error - ignore! Horrible not EMUI look - Ignore

3. Restore CUST (local update)

4. HARD RESET!!!

5. Update to B839 directly

I believe Hard Reset is essential within all or at least big version updates (like android 4->5 )! :cyclops:

Go to this thread: Working B817 for Non-Vodacom Users without CUST Error & Changing Vendor CUSTC Version

By majcomtech, Senior Member on 26th September 2015, 12:58 PM

Download the dload vendor Cust432 hw-eu b621. this is about 1 kb and then extract it and you will have UPDATE.APP for Cust 432 hw-eu. I have used this UPDATE.APP for B623 and it worked. Just put UPDATE.APP in your dload folder and update by local or forced update. It will perform factory reset. Then you do the same with the UPDATE.APP for B839 and you will not encounter any problem.

Just put this in mind the software is applicable to HW-EU. If you apply this other cust vendor, you will not obtain 100% installation of the software.

Inshallah this will help you.

Do you lose your data when you do local update? According to the guide of this ROM your user data will be erased regardless which method you use to update.

Not with a local update. You will lose data with the 3 button method.

Is there a way to get root access?
[Huawei Ascend P7] 87insane:
Install TWRP and go into recovery - you will see a question ... Yes ...

After a restart, you have to install superSU (it will be pop up).

After that you have root. If you want access to system you have to delete immutable.

Can't crypted the phone

Hello I've updated my P7 the 1st time with the B830 (I bought my phone 1 year ago so I don't remember which was the version on the Rom).

I had the Facebook bug on the videos and no keyboard when I installed the B830 version but I found a Cust file that allow me do restaure my phone with a keyboard.

Now I'm on the B839 and everything seems to work (Facebook videos , keyboard etc..).

But I have an issue that I also had on the B830 version. When I try to crypt my phone i can't use it because I don't have any access to a keyboard even if I have installed the original one (huawei swipe). So my only option after that is to restore my phone. It's not a vital option but it does bother me to have a room with "too many" bugs.

So I wanted to know if somebody had the same issue and how did you fix it?

Sorry if that have been asked before but I use the search "box" and I didn't find anything.

Also I have been able to root my old samsung phone but I've to admit that it's probably because of my English level, a complicated process or just bad genetics :D but I couldn't root my P7 so it might sound stupid and easy for you but if you have a tutorial that a 5 years old can understand I will appreciate :).

Thank you.

[Huawei Ascend P7] RejZoR:
I don't understand Huawei at all. Installed the B839 (official final version) and it failed the upgrade, but apparently it has done the upgrade. It was probably again the dumb CUST nonsense, I just wasn't staring at the screen to see what was the reason. Why the hell is this CUST **** failing non stop, but when you unpack the damn update, CUST files are present. Why are they just randomly not geting installed? For what moronic reason are they in there if they just don't get installed and then everything is broken from locked lockscreen-homescreen wallpapers, missing Motion control and other nonsense. It's all so stupid. How can official firmwares that even say they are correct ones for specific versions of the phone that I HAD and then it refuses to work properly. Like WTF!?

I said once that I'll only buy phones that have CyanogenMod support and apparently I'll have to strictly follow that next time. God damn prehistoric Galaxy S2 is running CyanogenMod 12.1 like a freaking champ with ZERO issues. Ascend P7, all broken with god damn official firmware and it's not even rooted or tampered. Ugh!?
[Huawei Ascend P7] sarcastical:
Rather than opening a new topic, I thought I'd ask here: since updating to this ROM did anyone encounter issues with touch/digitizer? Because sometimes my phone won't respond to touch and I have to lock it, then unlock it to get it to respond to touch. I'm trying to figure out if it's the update or a hardware issue.
[Huawei Ascend P7] SenGAndroid:
I've updated my phone from b832 to this this b839, and at first all was looking good. But now i have issues with my video player (the one i got with my phone). A lot of videos from my gallery appear corrupted. Then i deleted all videos, put them back again and i still had a few corrupted ones (which i just deleted), and the others work, but again few of them work very poorly. Fast forwarding is buggy, sometimes i just get sound and no image, sometimes the image is late a bit etc.

You think rooting my phone with that twrp and getting a new (hopefully better) video player might fix this ?

B830 --> b839

Hey guys,

I have a P7-L10, and I wonder if you guys could help me because after reading this posts, and some other on the topic I'm still a little bit confused:

- I'm on B830, should I update with the B839 update small file (74mb) or with the full version (1,26 gb)

- Will I lose all the data or is there a way for that not to happen? If I have to I'll do it, But I did a factory reset before doing the B830 update, and I have so many files and data in this phone and in each app, that will take me hours again to get everything as it was (again). And the recovery app from huawei I feel like some apps stop working right after the recovery. I maybe wrong of course.

Tks in advance for all of your replys :):)
[Huawei Ascend P7] rodlane:
The small update is fine. You won't lose your data.
[Huawei Ascend P7] bobyn:
You won't lose your data with the full version too, so I recommend to do it this way. Personally tested.
[Huawei Ascend P7] kolembo:
[MENTION=6966947]mostlystupid[/MENTION]

Help to back to KitKat

Hey guys, currently I'm in B839, but due to bugs with wifi and notifications I tried to go back to KitKat because this is my primary phone. However when I try to install the B800 transition firmware before the B609 version of KitKat, the installation goes to 95% and says "Software install failed!" :/

What should I do?
[Huawei Ascend P7] rodlane:
You have issues because of your cust version. Are you able to flash a custom recovery? If so, then you can flash MyROM 3.3, change your cust version to c432 and then flash official b609 (c432). From there you can flash b839 if you want to go back to lollipop, or flash the latest kitkat version if you want. There are guides around the forum that will help you with these steps. If you do this, you will probably want b839 though, because it is brilliant.
