[Q] Upgrading from b609 OTA to full version

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.

roll back to 609 from b830

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.

Huawei ascend p7 L-10 B853 local update

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.
Hammer

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

Install b182 (still MM) and you should then receive OTA upgrades to b38x, b39x (Nougat)

I still don't understand why you don't 'like' OTAs. In System Update, Settings, you can always choose Full Update instead of default Differential. And you can force afterwards Factory Reset if you think you need.
b386 is the last flashable by DLOAD. Btw, I was going back and forth through diff stock and rooted and custom ROMs, rollbacks, OTAs, and never had any error in installations. There are many threads with excellent info and guides, you must read and follow because in diff situations methods might be different. DLOAD is not always applicable

Unable to install stock rom Huawei P9

Hello!
I'm currently running on EMUI 4.1.1 (EVA-L09C900B182)
I downloaded the official firmware for P9 from Huawei website, extracted the UPDATE.APP with this tool https://forum.xda-developers.com/showthread.php?t=2433454 so i could get the stock RECOVERY.img.
I placed the UPDATE.APP in a dload folder on the root of my external SDCARD
Rebooted into bootloader, flashed the stock recovery (I had TWRP).
vol+, vol- and power button togheter, it tries to install but fails (software install failed! Incompatibility with current version. Please download the correct update package.)
I tried also with huawei firmware finder app and even if it says the firmware is approved for the installation when i verify with IMEI, it fails after (I tried EVA-L09C900B386).
I tried:
- with the in-app proxy, changing my wifi proxy to localhost:8080 and using the default updater
- downloading the package and manually moving UPDATE.APP in dload on my ext sd card.
What i would like to obtain is a full stock huawei p9 phone, so i could get the official android 7 and latest firmware.
Thanks a lot!

Best is to follow this guide and debrand the phone to C432.

I did something similar and ended up with C432B242 after some update with huawei firmware finder. Now I cant reach B397.. I've tried all the intermediate steps after 242: no luck. It fails during installation. Any specific instruction?

U have to downgrade to B182 and then upgrade to B360 FullOTA-MF-PV
When u upgrade to a new Android system u must flash FullOTA-MF-PV
U could try without downgrade first, but u cant upgrade to B397 because its not signed yet by Huawei, B395 ist the latest approved Firmware.

From b182 OTAs will lead up to b395.
b397 OTA is expected any day, meanwhile it can be forced (as well as the newer b398) from b395 by using no-check recovery:
https://forum.xda-developers.com/p9/development/eva-nocheck-recovery-flash-unapproved-t3705125

Update:
I reinstalled from b136 => b166 => b182
After that i tried b378 but now my build number is NRD90M test-keys
Will start again from b136 trying something different.
