Rollback software? - Huawei P20 Lite Questions & Answers

I've been having annoying bugs on my phone since emui 8.0.0.166, and after a ton of patches it's still there! The issues I'm talking about: themes don't apply properly, battery drains faster, slower bootup. I've done multiple resets with the recovery & settings, also cleared the cache.
Is there a way to roll it back to an older version without voiding my warranty or bricking it?

Anyone??

[Q] Softbricked/bootlooped Huawei Ascend Mate?!?!

i installed flashify onto my Huawei ascend mate 1, and install CWM. it asked to flash it, i pressed yes and it shutdown and won't boot normally, It's stuck on the logo mode.
if i press the power button for 10 seconds, it vibrates once before restarting normally and is stuck at the logo screen.
if i press volume - and power button simultaneously, same thing happens (note this is how i used to get into recovery mode before)
When i press the volume + and power button together after 10 seconds, it goes off and back on again Without the little vibration in the other cases, but gets stuck again
same thing happens when i hold down the 3 buttons all together.
i downloaded the stock rom from huawei's websit, put it into the dload folder and tried everything above 3 times. nothing happens.
i connect it to my computer for a chance to adb/fastboot, but in vain.
guys what can i do?
Hi, thank you for using XDA Assist. I'm going to move your thread here, http://forum.xda-developers.com/ascend-p6/ascend-mate where experts on your device can help you. You're probably going to have to flash the stock firmware on your device to get it working again.

This is the Mate 2 Forums. Totally different device. You probably didnt unlock your bootloader. http://forum.xda-developers.com/showthread.php?t=2642403 Try there.

If you can goto fastboot, simply install recovery.img from UPDATE.APP(use huawei update extractor to extract img).
then copy update.app to dload folder in sd card and poweroff device.
press vol down + power button, it will boot into recovery and install UPDATE.app.
I faced this problem when from 5.1, i installed kangvipB015. it worked the way i told above.
Okay... I had my phone plugged into my usb 3.0 then I plugged the phone into my usb 2.0 port and phone started responded to my holding down volume and power buttons then phone booted up into unknown update and now everything is fine.... weird though
Huawei x2 loop
Hello. my X2 boots and reaches lockscreen, when I input my password a window comes up that says the system is not responding. After I click OK or WAIT the homescreen shows up, but after a while phone restarts and the same sequence happens again. I have tried booting into safe mode but the same thing happens. I also tried POWER plus VOL UP to clear cache. I have left the phone off and with zero battery power to simulate a battery pull. I cannot RESET however since I have valuable data on the phone which I cannot lose. Before this I was attempting to delete files by uploading to Google Photos, the phone froze so I restarted. When it booted that is when the looping began. I don't remember the version my X2 is in but since I got it I only had updated it once last year. I hope someone can help me.

Hard Brick ?

Ok, I just want to know if my phone is hard bricked, or if I still have a chance...
I tried to install an update (121 to 170 for plk-l01) on my rooted phone, with local update. It didn't worked, twrp show errors everywhere, and after turning off know i can't access the recovery. when I press on vol+/- and power for 10-15 second, it vibrate but nothing else.
Is there anything I can do ? my phone isn't recognized by my computer, by the way...
Why you did that? You can't update rooted phone

Try to boot into fastboot (phone turned off - connect with data usb to the computer - vol down + power on). Extract rom which is currently installed or higher (for your respective model) and flash from it:
fastboot.exe flash boot BOOT.img
fastboot.exe flash recovery RECOVERY.img
fastboot.exe flash cust CUST.img
fastboot.exe flash system SYSTEM.img
Reboot.

Thanks, but unfortunately, it just 'boot' as others reboots. it vibrates, doesn't get recognize and doesn't turn on...
If anyone have any clue on how to force recognizing the phone storage, it might really help ^^
That is what my phone is doing, I tried to upgrade to marshmallow though with no root!! I put the zip in the dload folder and went through the upgrade process everything went through the phone rebooted and now its dead. Blank screen and if you hold power after a few seconds it will vibrate but that is it. I presume its hard bricked? no matter what combo of buttons I press I cannot get it in to fastboot.

ok I'm looking for a solution for hours now... so I just lokked how works our phone and I think the trouble must be in the preloader, because I can't even make my phone being recognized by any computer and I can't access to recovery.
I found this :
http://www.droidgyan.com/soft-brick-vs-hard-bricked-vs-broken/
Which could help. I'll leave that topic on for some days (if it could help someone) and I'll open a new one to know if there is any easier solution ! thanks and good luck.
I sorted mine, it was only 2 days old so I got it replaced by the shop I bought it on. I would say it was something like a pre loader from what I saw. I have never bricked an Android phone and I must have had 15-20 of them since my first HTC Magic and before that Windows Mobile which again I messed with tons reloading with all sorts of ROM's!! These phones are wayyyy too sensitive to being messed with, I always remember though that you never mess with the boot loaders, but it looks like these updates do to get it bricked to that point.

Do you have adb debugging activated on the phone? Did you try to hold phone buttons long enough?

Euuum..... maybe yes ? I used fastboot but I don't think it really matters now, there's nothing working on it. And I've sometimes hold the buttons for 30-40 second while praying lol

local update
I just hard bricked my Honor 7 the same way. Is there really no solution? Other China-Phones are pretty much unbrickable, since you can always fix it via the preloader. No such luck here? Back to the shop and hope they actually replace it? While I admit it was stupid to just hastily start the OTA while having twrp and not stock recovery (no root, though), this is a terrible design flaw on Huaweis side.
Anyway... any hope or no chance?
i just hard bricked my honor 7 PLK-L01
it the same thing it is doing . not recognized by the computer
tried all the combination of buttons. but no hope
and it only vibrates when tried to turn on
Need urgent help please
@Idiocrate try to boot into bootloader mode just by pressing Vol DOWN button and simultaneously connecting it to a PC, don't press Power button, if it boots into it, then follow the method given by @piskr in third post.

How to update?: PLK-L01, Android 5.0.2, EMUI 3.1, C432B180 -> to latest VER? (B330?)

Need simple steps how to update my Device from B180 to latest firmware?
Just download this; http://www.hihonor.com/uk/support/details/?DOC_ID=77509
Put the "dload" folder in your sd card. Shut down the phone and press Volume Up + Volume Down + Power Key. Release power key when you see the honor logo. Wait a little bit and update will start. After everything I need you recommend to do wipe your data and cache with Volume Up + Power Key.

You do not need the cable when you are updating the phone. After you put the dload file, plug out the cable. But I do not know your stucking problem. Maybe it's about your sd card.
If retained after the upgrade of personal data, settings, the update does not complete. Repeat the update, and the second time it will be complete.
This only applies to the downloaded file update is not OTA.

[GUIDE] This works: Unbricking P10 using HWOTA on Windows

I really wish I had acquired root in a stable and reliable way but it looks like this is not going to happen for me on the P10 VTR-L09C432, so this post is about Resetting the phone.
After unsuccessful attempts to acquire root (I know Magisk is supposed to work, but it left me an unstable system), I had to restore the phone. TWRP Restore left me with a brick. I tried several unbricking methods (this Guide did not work for me), but the only one that worked for me is the one with HWOTA. In case this can help someone else who ends up in the same place, I thought I'd share my experience.
The method is outlined here but for reinforcement here are the basic steps and some extra details.
- You will need to download all three firmware files. I downloaded the latest ones for my version (VTR-L09C432). There are several ways to download these files, you can research that separately. In my case I used FirmwareFinderRewrite.exe from the "Firmware Finder" package but did not find that intuitive to use at all.
- These three files need to be renamed according to the naming convention in the article, and to be copied to a HWOTA folder on your SD card. For this, if you are bricked, you will probably need to remove the SD card from the phone, copy the files via PC, then reinsert the SD card into the phone.
- To reset the phone, there are two steps in HWOTA and one step in EMUI
- To run HWOTA, you run the update.bat file on your Windows machine (possibly as Admin, not sure)
- First step with HWOTA: you boot up your phone in Fastboot mode (connect USB, long press Volume down)
- Second step with HWOTA: boot up your phone in TWRP (unplug USB, Power until vibrate, then quickly press Vol Up then release power, keep holding Vol Up till TWRP appears), then plug in USB. To boot in TWRP you have to hold your breath just right, make sure to ask in the forum if you are not getting the key sequence right. For me, once I get the vibration from holding Power down, it takes probably about half a second at that stage to press Vol Up THEN release Power. You have to keep holding Vol Up.
- The EMUI step: once HWOTA has done its work and you reboot the phone, EMUI will offer to do a factory reset or a Wipe. I did the Wipe step first then the factory reset.
Good luck!
I didn't work for me, because one of the requiments was "bootloader has to be unlocked".
I finally tried this and it worked!!

I tried running the update.bat as admin, but just opens and closes automatically, I canĀ“t even read what it says.
Hmm, how about locked bootloader and FRP? Will it work?
