Hi,
I want to upgrade my firmware, from OTA b609 to full version b609, but every time I tried, it FAILED.
Maybe someone can help me.
Thanks
more information..
recovery: stock or custom?
what have you tried so far to upgrade?
Gesendet von HUAWEI Ascend P7-L10 B609 - rooted
It's stock.
I downloaded full version b609, add it to dload folder on SD card and I tried a local update from phone's actualization software.
After 5% loading the FAIL message show's up.
Hi, I updated my phone by manual way with dload folder from b609 to b621 to b623 to b630. Somehow something went wrong. b830 seems to be working but cant conet to te network. cant even change the motive on my phone. tried to roll back to 623 from 830 by simply using dload folder but it does not work. it seems that it downgrades but the soft is still b830. can i roll back to b609? the most important thing is that i can not even do the factory reset. it resets up to about 40 per cent and then the fail appears. when i turn on the phone it looks like it did work becase i have to set the language and the display settings but still cannot connetc with wi fi to the internet. i am hopeless. can i do it in such a way not to loose the guarantee. i think i still have it. i do not want to wait for the phone for a month before it is fixed.
No worries, you have to flash B800 (official Huawei downgrade firmware) first. After that you could go for B621 and after that B623.
1. flash B800 transition pack from here http://download-c.huawei.com/download/downloadCenter?downloadId=49144&version=114340&siteCode=de
2. flash B621 over B800 - download from here http://download-c.huawei.com/download/downloadCenter?downloadId=48964&version=113966&siteCode=it
3. Now u can flash B609 over B621 - download from here http://download-c.huawei.com/download/downloadCenter?downloadId=37141&version=64532&siteCode=it
thanx

Great. Thank you for your answer. I just gave up because I was afraid I will lose the guarantee if I will try to do something myself. But if the problem appeers again or if they will want to charge me with the cost of fixing it. I will use your guide. Thank you

Just find no bootloader unlock.IMG for the B830. for B621 yes. but not B830
You can request your bootloader unlock code here (http://emui.huawei.com/en/plugin.php?id=unlock&mod=detail). Through a fastboot command you can unlock the BL afterwards.

Hi all,
I updated my P7 with the B853 firmware. I want to downgrade but I'm not abble to reload any old firmware.
In the option I don't have the possibility to do a local update. When I reboot the phone with +- and power any update can be installed.
Can you help me to downgrade my phone ?
Thank you very much.

When you install b853, you are losing updater app, you will need to download transition package and do a force update, put it on sd card in dload folder, turn off the phone and hold Vol up Vold down and power button for a 10 seconds, after you installed transition package, flash kitkat firmware that you had before lollipop.
I tried to force the install for B126 or B621 in kitkat but without any success. what kind of "transition package" do I need to install ?
Thanks,
Hammer

yes, with dload method. and now i'm want to downgrade to marshmallow again..
Me too. Roolbak erreur
You have to download the rollback package from huawei support, install the update.app from the rollback with the 3 button method, it's around 100mb, or so. Then download the marshmellow firmware, install it with 3 button, then you will have 6.0. You probably won't have the themes, it can be solved with twrp, and flashing the eu (or the region of yours) cust package.
I did that , and now I have c900b170. everything works ok except themes .
if I install EVA-L09C432B136 through dload method, should everything work ok? I will be able to get later the ota nougat update?
