Since the bootloader is unlocked you can use this: https://forum.xda-developers.com/huawei-p20/how-to/guide-how-to-rollback-emui-9-beta-to-t3841687
It works for me
Replace the TWRP image on the images folder with this one: https://forum.xda-developers.com/huawei-p20-lite/development/recovery-testing-t3783587

After flashing twrp and restarting, vol+ doesn't work, boot normal way.

Flash p20 lite twrp, of success, restart phone, when there are 3 options, press power biton to boot, press vol up 3 sec to enter erecovery etc, and do nothing for 5 secons aitomatocaly boot in System you need to press vol up 3 seconds, then, when you are in e recovery, use option emergency backup, or somthing like that, then phone will reboot to emergency System mode, press option factory reset or somthing like that, second option from top if im coretly remeber, after that you will be in twrp recovery.
So,. If want to use downy, replace downy twrp with p20 lite one, do all what downy said, but, where you need to boot in twrp, do as writed i, and continue with downy after you are in twrp. Good luck

OK, do it in same way, it works. Earlier flashed this twrp, but after few seconds phone restart to system. Working and don't know why

Did you manage to downgrade?

Yes, thanks a lot.

[Q] HUAWEI Ascend Y300: Flash Recovery with a Locked Bootloader

Are there other ways to flash a recovery with a locked bootloader?
My Problems:
I can't flash my stock recovery through fastboot with a locked bootloader.
I can't boot into my recovery because my current recovery is TWRP 2.5.0.1 and I have a locked bootloader.
I can't unlock my bootloader because I have used an IMEI Hack Tool and set my IMEI to 0 (I guess).
I can't boot into my ROM because I used an IMEI Hack Tool.
I can't Force Upgrade too (Vol Up + Down + Power). It only shows a pink/purple screen.
Solutions:
I can only flash a recovery with an unlocked bootloader.
I can only boot into a recovery with an unlocked bootloader (except for stock).
I can only unlock bootloader if my IMEI has restored.
I can only restore my IMEI if I can boot into my ROM.
I can only boot into my ROM if I have a stock recovery.
I can only Force Upgrade if I have restored my IMEI.
If I could only restore my IMEI through fastboot, that would be great!
So, please help!
You cant restore stock recovery ?
You cant enter to trwp ?
You cant restore IMEI cuz rom bootloop ?
You cant force flash stock firmware cuz fastboot is pink ?
I also "zero" my imei many times to flash stock firmware, but i allways can enter trwp and restore buckup or flash rom in zip

If upgrade fail as step 2/2 your IMEI its not "zero" cuz IMEI block upgrading firmware from branded to nonbranded

OK, lest start from beggining
1.You must unlock bootloader by code ( first run check Lock / Unlock status ) (fastboot mod)
2. Flash TRWP (fastboot mod)
3. Flash SuperSU or Superuser zip (trwp)
4. Backup IMEI on running rom
5. Hack IMEI on running rom
6. Update phone by forceupdate flash update.app (rom in root of sd card > folder dload > update.app)
7. Run stock rom , lest install, shut down phone
8. Run TRWP to install SuperSU/Superuser zip
8. Restore IMEI (on working rom)
9. Go to TRWP and Wipe dalvik cache
10. Now you have working newest stock rom with root
So :
1. You cant have trwp in lockedbootloader
2. If update fail on 2/2 IMEI is not "zero"
3. Pink LCD on "update mod" = no rom in sd card
Next :
Hold Vol Down + Vol Up + Power to forceupdate firmware mod
Hold Vol Up + Power to run TRWP or stock recovery ( hold about 5s)
Hold Vol Down + Power for fastboot mod (5s-10s)
If you now have locked bootloader , with stock recovery, and force update fail, you cant unlock bootloader and flash trwp > Last hope is in "oryginal" rom, your IMEI will not block it.

Wait, let me put this in summary:
1.
- I have a locked bootloader.
- I can't unlock the bootloader because it says "recovery image verify failed".
- It can only mean one thing: my IMEI must have changed.
2.
- I have a TWRP recovery.
- At first, my original recovery was the stock when I have a locked bootloader.
- Then I flashed the TWRP recovery even if I have a locked bootloader and didn't warned me. (Shoudn't it be accepted to be flashed since I have a locked bootloader).
- In my experience, if I have a stock recovery when I'll hack my IMEI, it will format my cache and data and let me boot into my phone.
- If I have a TWRP recovery when I'll hack my IMEI, it will only redirect me to the TWRP menu.
3.
- I can access Force Upgrade.
- But it doesn't show any text. (For example: it doesn't show if it is unpacking or installing, only a bar.)
- When I access Force Upgrade, the loading stops at 1/4 of the bar. (So I'm not really sure if it failed at step 2/2.)
So my questions are:
1. Why can't I unlock my bootloader with my original IMEI's unlock code if my IMEI is not "zero"?
2. Why is it when I Force Upgrade, it doesn't show any text?
3. Why did fastboot accepted the TWRP recovery being flashed when my bootloader was locked?
And, what do you mean by "original"? Do you mean the B182 firmware upgrade, not the B175?
After hacking IMEI you cant have stock recovery, cuz you need root for shell script. So its not making "auto wipe" to change OEM info.
TRWP should not be installed on lockbootloader, but i dont make it ...
So , do you have working trwp or not ?
Oryginal firmware ... version when you get with phone, like my Y300-0100 branded T-Mobile PL B167

I am sure i have twrp.
If i have a stock recovery, i would be able to boot into recovery.
Based in my experience:
1. To hack the imei, you must first root your phone.
2.a. Next, the phone will reboot, but it won't boot into system.
2.b. Fastboot, force upgrade, and recovery is still accessible.
3.a. If you have a twrp recovery when you hacked the imei and rebooted, it will redirect you to the twrp menu.
3.b. If you tried to restore from twrp recovery, it still won't reboot into system.
3.c. If you have a stock recovery, it will directly boot into stock recovery and format your cache and data and reboot to system (still leaves your imei to zero)
4. If you go to force upgrade, you can flash any official roms (leaves your imei to zero)
5. After you have flashed a rom or was redirected to stock recovery, your phone will reboot.
6.a. Then root your phone and restore imei then your phone will reboot.
6.b. If you have a stock recovery, it will wipe your cache and data.
6.c. If you have a twrp recovery, it will redirect you to the twrp menu (you can manually reboot into system)
Am i right?
And where can i get the original rom for my b182? There's no local huawei store here.

I have a big problem. My Ascend y300 started to work strange yesterday, my PC didnt see the internal sd nor the external SD correctly. Today I restarted it and now I get blue screen when I start it. I had TWRP installed, but when I try to access it, it gives blue screen aswell. Any solutions?

My problem is a little bit more complex unfortunately. I tried what you said. When I push the buttons to enter fastboot, my phone dont freez at splashscreen and I get bluescreen. When I connect it to my PC my PC recognizes it though, BUT ADB cant see it. I reinstalled the drivers any times, without success.

That is the most strange part of the story. I totally did nothing. I opened bootloader, installed twrp, rooted it, installed init.d support, installed a ramscript. The phone worked totally fine until yesterday. I did a restart yesterday and bumm, bluescreen. And I did nothing before this happened. Srsly, no problems detected, it came from nothing...

Can't you really boot into fastboot (Power + up)?
Hold it for like 10 seconds.
If it still shows blue screen, try connecting it to pc, maybe it'll read it.
Then erase recovery and flash twrp.
Wipe everything and restore a backup you made.

Well, my problem is, that despite of the blue screen, fastboot seems to work. My pc sees my device, BUT ADB refuses to see it, and I dont know why. I will try it from win xp under virtualbox now.
hi Gery
How do you manage to get the phone into fastboot mode?
my y300 also enters blue screen everytime now. I try to press voldown + power for like 10 seconds, yet the fastboot command is not working.

Well, that's perfect! If the PC can read the device from fastboot, you can erase the recovery and flash the twrp and restore from backup. But if it still goes blue, flash the system, data, cache, boot, recovery from your twrp backup.

I tried to install a custom firmware on my phone, and now, my phone is locked in "Firmware Update" screen (same as when you press volume + when phone boots). I used LGUP tool to flash stock firmware, but with 6.0.1 shows an error [Error code=0x(2 numbers and 1 letter)]. And with 7.0 LGUP crashes. Any way to fix this?
PD: Cannot go to TWRP recovery
PD2: Only can go to fastboot

allright, gonna try and help you.
1st, Is your bootloader unlocked? If so
try to flash twrp 3.0.2.1 in fastboot. Then boot in twrp by holding volume down and power button.
If you get into twrp you probably can flash a rom.

Start your phone in fastboot mode, flash TWRP, disconnect and reconnect the battery.
Now hold volume down + power until you see the LG logo, keep holding volume down and let go of the power button for a moment and then hold the power button again while still holding the volume down button.
You will now see a prompt asking if you'd like to factory reset, press yes to both prompts.
You will now be inside TWRP.
Which variant you are using.

I've tried this process myself and I get the same result. Reply Yes, Yes to factory reset and it *should* then start TWRP but it doesn't. You end up with a wiped phone and have to start all over again. Tried process a few times and never works.

The only reason it wouldn't work is if you did not flash TWRP correctly, make sure flashing TWRP with fastboot was successful before disconnecting the battery and entering the factory reset prompt.

Yes I know it is very annoying when that happens, you should definitely flash the latest version regardless, I'm sure you won't have the problem after flashing :good:.

Found it! After you install twrp, you just execute 2 more commands:
fastboot format userdata
fastboot format cache
Don't reboot, just turn it off.
Works like a charm!

TWRP flash succesful, but no recovery boot.

Hi All,
I have an Redmi 3 pro with unlocked BL and the latest "official" weekly 7.3.9 from xiaomi.eu and latest TWRP 3.0.2.0 from official twrp site.
I am unable to flash twrp.
I flash it with fastboot flash recovery recovery.img then boot into it using fastboot boot recovery.img with no issue at all.
Then,
if i reboot into recovery from twrp itself it still works.
if i let it boot the phone in its bootloader (POW+VOL_UP the one where you can choose "download" "fasboot" or "recovery") and i select recovery, it does not boot. The phone boots instead.
if i choose from the updater to reboot in recovery, same.
if i choose from flashify (which shows me "stock recovery" is installed), same.
if i use adb reboot recovery same.
i can only boot it using command fastboot boot recovery.img.
It just looks like the twrp flash says OKAY but it's not being flashed.
I've also tried cofface recovery with no success.
i've also tried official twrp app with no success.
everytime flash goes fine and successfully, but i'm unable to boot the phone in recovery itself.
i must always use fastboot boot recovery.img
Hints?
Hi @lalontra,
Use combination of Power+Vol(+)+Vol(-) button. It should boots you to recovery.

It is error in this release ROM
You are not alone, its problem of this concrete ROM from 9.3.2017 ido.! You must flash different ROM, previous release.

The Volume+ and Volume- and Power worked for me even with the rom error. Hold all buttons til you see the Mi logo, then release Power but keep holding both of the Volume buttons. I also reflashed TWRP Recovery via Fastboot, so maybe that was it.
I'm also facing a problem around TWRP 3.0.2.
But different situation
I always failed/unable to boot into recovery or bootloader everytime I click reboot recovery or bootloader button in TWRP recovery mode.
I still try to find a way how to fix it. Because all the articles that I found always explain about "cannot enter to recovery mode from the system", not from the recovery mode itself.
Do you got anything from all the steps above? Please let me know if there something u can share. Thanks in advance
Here's what happened in my xiaomi redmi 3 pro. Always failed to boot into recovery again or into bootloader mode when I'm still in TWRP mode.

Xiaomi Mi 8 Lite Re-Lock Bootloader

So I actually tried installing the TWRP a couple days ago. When I tried to boot to recovery with button combination Vol Up+Power Button it always booted to stock recovery. The thing here is that from the fastboot tool when i boot to TWRP with
Code:
fastboot boot twrp.img
after
Code:
fastboot flash recovery twrp.img
it boots to TWRP and everything works fine. However, since that day i tried flashing the TWRP my phone is lagging very much. I tried to Hard Reset it but it still lags seems like there are some bugs and sometimes a "System UI has stopped" error pops up and it suddenly reboots.
First question: What causes the lags?
Second question: if i re-lock bootloader will the problem stop?
Third question: May that be the case that the .img file of the TWRP has been installed but cannot boot so it might corrupt the bootloader re-lock and hard brick my device?
I'm thinking of relocking it with
Code:
fastboot oem lock
Also sometimes wifi suddenly turns off and won't turn on unless i reboot and it doesn't always work and some system apps stop working as well. when i reboot for the couple first minutes the phones works great no lag no bugs, nothing. Plz someone answer asap i'm going to need the phone and i cannot work with all those lags.
Download the latest fastboot stock rom from here : ( not recovery rom, download fast boot rom.)

Flash it with mi flash tool and check the option re lock. Or lock something like that. And the problem should be fixed. Your bootloader will be relocked and your recovery partition should go to normally.

So I actually tried installing the TWRP a couple days ago. When I tried to boot to recovery with button combination Vol Up+Power Button it always booted to stock recovery. The thing here is that from the fastboot tool when i boot to TWRP with after it boots to TWRP and everything works fine. However, since that day i tried flashing the TWRP my phone is lagging very much. I tried to Hard Reset it but it still lags seems like there are some bugs and sometimes a "System UI has stopped" error pops up and it suddenly reboots.
First question: What causes the lags?
Second question: if i re-lock bootloader will the problem stop?
Third question: May that be the case that the .img file of the TWRP has been installed but cannot boot so it might corrupt the bootloader re-lock and hard brick my device?
I'm thinking of relocking it with

If you want to relock your bootloader, then simply flash the official firmware for fastboot, then select the clean all and lock option in the miflash tool, then the bootloader will be locked
