Oh...
first do a Factory-Reset form Recovery (vol+ power) if not correct fixed so...
You Should have done thsi role... [ b158>b133 so b133>621 so b621>b623 so b623>b830 ]
way from b158 to b830 is [ b158>b133>b621>b623>b830 ]
you just now try to downgrade that b830 to b623>b621>b133 so upgrade thats to b830 or b158

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

First you must flash stock recovery. You can extract from another full rom 7.0
Second you must have downgrade pack for your region and mobile operator.
Next you must have full rom 6.0 for your region.
You must have all file because you don't want debrand your firmware

Thanks, actually if i want debrand my phone whats the diference? Because I think I don't care...
Also, where can i find all of these files you write about?
I'm really lost with all firmware versions ... Does it matter if my version is EVA L09 C33B363 and i flash stock recovery from another version??
Also, my bootloader is locked, do I have to relock it? Does it even possible??

If you have locked you must unlock again. All file you can take from forum. Debrand it's unlock warranty and sometime you loose your guarantee. But what region you from

Here you have how debrand
https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
If you debrand you can then flash stock recovery flash b300 and then b136 and do it wipe in stock recovery.
When you want debrand first you see your cust be c900 and then you must flash stock recovery do it wipe system/data and cache
If you do it your cust change to c432 and then must check your region using dial pad
*#*#2846579#*#* then push 3 and 4
If you see your vendor: hw and country: Europe
You can downgrade to b300 and then to b182
You lose your theme and you see ugly icon then do it wipe system/data and cache in stock recovery
After this you have update to b383 then b386 next to b391 and final to b393 or b394
I have b393

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

downgrade?

Hi guys
Someone has succeeded with downgrade from oreo to nougat ? I need go to huawei service, to exchange the display, but problem is "relocked bootloader"
So many tutorials here, which to follow for downgrade and have "locked bootloader" ?

You can use HiSuite or install the downgrade firmware through Firmware Finder. It has the normal Nougat version, but in the description it tells that it downgrades.

HiSuite tells me that I have the latest version so.. I cant downgrade from HiSuite, or if i can tell me how to do it please

@yungshadow
As M1chiel said, try with Firmware Finder.
Remember!! Everything is on your own risk!!
Don't know which version you have, but for me this is the roll back firmware...

Let's try. But.. still 0%

If you use proxy option, you have to set proxy in WiFi settings.
localhost and 8080
Then start download and wait until 4-5%, then disable proxy and continue download.

i'm using DNS. Now 11% XD

ok i'm finally have emui 5. Now i must rebrand ?

That I don't know, I already didn't understand why you wanted to downgrade ??

I need to have bootloader status "locked" not "relocked" so i must rebrand to l09 and back to l29 yeah?

Ok guys
I Found a solution.
1. Downgrade from Oreo via FF using B185 (downgrade firmware) thanks
djg269 said:
2. Download some L09 firmware and install via FF
3. After installing I had bootloop (huawei logo, booting system for 10-15 sec and still restarting)
4. Enter eRecovery VOL-UP + POWER > Wipe data and cache
5. After Wipe phone said it's still L29 but now bootloader is locked not relocked
So i'm done now

I have a small question - in FF it says to make sure my current version is not "unlocked" - does that mean the bootloader or...? I just want to downgrade to B180 so I can install HuShed. I'm on L29C432B360 currently.

I don't remember this information. Could u send here Screenshoot with that dialog from FF ?

Same screenshot as post #4 -> https://forum.xda-developers.com/showpost.php?p=76556011&postcount=4

I used b185 from b360 with unlocked bootloader and I had no problems.
You should use b185(rollback firmware) and after this will be able toinstall whatever you want

Alright, last question - I have TWRP installed for 8.0. Will this affect the downgrade somehow? Because for example I can't install OTAs with TWRP. I'm sorry I'm kinda new to these kinds of stuff.

I didn't have installed twrp for 8.0 when i Decided to do downgrade so I think it doesn't matter but you can flash stock recovery for 8.0 if u want ofc.
Now i'm on 8.0.0.365(c432) but with official OTA update
