Rollback (or downgrade) from B190 to B150 - Huawei Y6 Questions & Answers

I want to rollback to B190 to B150. Tried with /dload (B150 update.app), no success. Mostly because, there is no root on B190 with Kingroot. I did not tried Magisk, yet. Have to flash TWRP with ADB. Not likely to me.
So, is there any chance for downgrade?
Phone came with B150, upgraded to B170, then B181 and to B190.
Device is SCL-L01C432.
If You need more information, please tell me.

With the fastboot method if you have the bootloader unlocked, there are many tutorials on the net. But how did you rate an upgrade to the B170 ??

But I am not really, really sure, which one will work with B190?
You mean flash custom recovery, custom ROM, then try to comeback to stock recovery and stock ROM?
Ok, looking now inside B190 update.zip and there is B190 recovery.img. (12.recovery.img in Huawei Update Extractor)
I see this with magisk:
https://forum.xda-developers.com/showpost.php?p=73838305&postcount=24
Should I try for B190?
Last version of KingRoot (5.3) is not working.
I found (on internet ) for some other Huawei phone, there is some special "middle package" (update.zip) to get the possibility for downgrade. Maybe I need that "special package"?

With Firmware Finder.
There is update (for me) numbered under #63737.
Update from:
SCL-L01C432B150CUSTC432D008
to:
SCL-L01C432B170CUSTC432D004
Put in /dload and update.
Have not used much B170, but B190 work smoothly.

You just have to download the b150 version and after extracting with Huawei extract the necessary files including the recovery stock, make the flash with fastboot:
fastboot system system.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cust cust .img
quick reboot

I followed Your instruction for fastboot.
Boot, recovery, system flashed. Cust cannot be flashed. They are from B150.
Code:
target reported max download size of 266338304 bytes
sending 'cust' (194411 KB)...
OKAY [ 6.275s]
writing 'cust'...
FAILED (remote: Command not allowed)
finished. total time: 6.283s
Tried to flash whole B150 (UPDATE.APP) with:
Settings -> Updater
EMUI Updater (Volume Up + Volume Down + Power)
Project Menu -> Update (it mean *#*#2846579#*#*)
Nothing work.
Now I have "half" B190 and "half" B150 in my phone.
Is there any way to flash whole B150 (UPDATE.APP)?
Please? Anybody?
Have weird problems, like i cannot remove widgets, launcher crash sometimes, etc...
I do not know is there any downgrade package? Or something?
Maybe I need SCL-L01C432B190CUSTC432D002 firmware? If exist?

Given that I still do not understand how you have run the B190 version on this device, try to install this version always with the fastboot method: http: //huawei-firmware.com/rom/huawei-y6/scl-l01/1027
After install any other updated B150 version and it should work.
The cust.img file I do not know why but it does not work with fastboot.

[Honor 5x KIW-L21] Bricked

Hello! Some day i want to downgrade my Marshmallow to Lollipop. I installed stock ROM to my Honor 5X but in older android - Lollipop 5.1. And I get bricked it. On start on screen i can see first-step logo honor after it i can see second-step honor's logo and here i wait 30 minutes and nothing 45 minutes and nothing. Worse is this I can't back to my stock Marshmallow, when I'm installing my previous ROM - MM i get the same brick on second-step logo. I installed a few more ROMs and nothing. My bootloader is unlocked but when i try to flash cust/system by fastboot appear an error. FAILED (remote: Command not allowed). I think i tried everything, thank for help me.
PS. Sorry for bad English :/
EDIT.1 I tried to use this method from Thread: http://forum.xda-developers.com/honor-5x/help/ive-bricked-honor-5x-t3324225. But the same problem at fastboot.
cust and system won't get flashed on 5X, try force updating it with an UPDATE.APP package for your device.
Put it inside dload folder in root of the Sdcard, and press all three buttons (Vol UP + Vol DOWN + Power) after switching off your phone, to start updating.

Thank you. But i tried to get ROM back by UPDATE.APP and when i want to go back to Marshmallow i get second-step honor logo and nothing after it. When i want to get Lollipop i have error "Software can't be installed" - something like that. I heard something about "Transition package" or "Downgrade Package" ? Maybe it can be work. But i can't find those packages for honor 5x KIW-L21.

If the Marshmallow update went through a bit, then you'll need transition package, so take on some pain to find it. It should be out there somewhere.

If you use the this version of TWRP > https://www.androidfilehost.com/?fid=24588212152305793
you can flash system.img and cust.img extracted from your Update.APP with HuaweiUpdateExtractor
fastboot boot twrp.img
then copy the files to the phone
then choose Install / Install Image / system.img or cust.img or recovery.img boot.img ..you choose
Also just saying your have a L21 does not help
is it KIW-L21 C432 or KIW-L21 C185
Now i backed to B130 and i have loop with message Optimizing system... this process going to 100% and phone reboot. And it looping.

if you successfully flashed System.img - boot .img - cust.img and recovery.img you can now use the dload / Update.app

Ok, one more time. When i'm installing any ROM B130 or B330, stock or official doesn't matter, the same problem. After installing rom by UPDATE.APP my phone booting and booting and booting and nothing. When i'm installing rom images by TWRP - boot, cust, system It's the same problem Booting, booting and nothing. When i tried to flash rom by fastboot i have error: FAILED (remote: Command not allowed). I would like to try this: http://forum.xda-developers.com/honor-5x/help/how-restore-cust-partition-t3356769 But i don't know how to access to adb shell: when i type "adb shell" in cmd where i have adb it say to me: error: device '(null)' not found. I don't know what to do more.
How much time honor 5x system is installing?
How i can check my honor is KIW-L21 C432 or KIW-L21 C185?

If you tried to install the wrong Update.app the updater would get to 5% and stop and eventually just reboot. Did you actually watch the update go to 100% and reboot ?
I think i found source of my problem. When i want to downgrade my system was B340.
I read something about downgrade. Without Transition Package I can't downgrade my system I can install only the same (B340) or higher.
This making brick when i'm installing B330 or B140.
Now i'm trying to install OTA B340 and i have another problem,
when i have B330 and installing B340 by small OTA 124MB I have stuck on 5% of installing. It becouse:
EDIT 2 : If you come from B330, don't try to flash the small B340 update as local update has simply been disabled by theHuawei/Honor devs !
Worse, with B340 you won't be able to downgrade to any lower version : at least not easily... INFO FROM: HERE
Click to expand...
Click to collapse
But when i'm installing B130 by TWRP and upgrading to B340 by big upgrade (1,36GB) it's stucking on 0% and i get info: DO NOT UNPLUG....
I think that becouse my version isn't B130 only B140. I'm checking it by DC-UNLOCKER. Output from it:
Code:
Found Phone : KIW-L21

Normally restoring a TWRP backup is no different than flashing System.img and boot.img

I know this isn't the thread for it... but there is no forum for the ZenFone 3 Zoom.
I have US model and I've unlocked the bootloader, installed TWRP, rooted.
I want to install rom update that was just released last week. It obviously doesn't flash in TWRP. I also can't unzip it without corruption errors. Redownloaded the ROM multiple times from ASUS.
I assume to update stock rom with an unlocked Bootloader we'll need stock recovery??

And where was that twrp install originally from? I haven't found an image for this model specifically.
Also, does this bootloader unlock still allow the pushed OS updates from ASUS? Want to make sure I can get Nougat when it comes out!
Hey guys,
I need some help. I installed the apk to unlock the bootloader and my phone was fine, but after flashing twrp and installing the zip for supersu via twrp, my phone has been stuck on the boot screen. Now it says "The dm verity is not started in enforcing mode and may not work properly" when booting up. I can get back into twrp, and I've tried wiping the dalvik/art cache, system, data, and cache, but my phone still won't boot up. It's stuck on the ASUS boot screen, and I have no idea what to do now. Any help would be greatly appreciated!

No. The last update WW_V11.41.87.2 is not available for my OTA. I can download the zip though and flash. I haven't actually attempted to do this yet. I plan to flash it today. Not sure if I'll be able to do it through twrp, or if I'll have to flash back the stock recovery first.
So does this change the bands available with it? I have the WW ROM but want the additional bands the US ROM has.
why I only have system.new.dat where can i get the system.img? thank you
How did you get on with flashing the update... did you have to revert to stock recovery and if so which did you use? Thanks for your help with this.
Can I ask where/how you got the stock ROM? I'd like to make sure that these are updated/available somewhere for people on this device to use as needed, and ASUS seems to only have the updates on their website.
Is it possible to relock bootloader after converting to WW?
I'm interested in this phone. Do you know if this one is going to be shipped later this year with Snapdragon 630?. I hear something similar in a YouTube video.

How to get back to a Stock ROM

Hi,
sorry if i'm the 100th person to ask this question but how can i go back to the stock ROM with OTA?
I currently have a flavor of LinageOS with the Turbo Z kernel installed on my phone but it's just to buggy for me. I want to have root access on my phone for various reasons though.
I tried to just download different (6.0/7.0) stock ROM files but i can't install them with TWRP. I know that 7.1.x was released but i can not find the ROM for it.
What is the easiest way to just go back to a stock ROM? I know my way around the console but i don't want to brick my phone. I made backups of my files and also with TWRP so data loss is not an issue.

First things first.
On which bootloader are you, MM or are you on Nougat. If your device has been flashed with the 7(N) bootloader, you cannot flash the 6.0 stock, you will have to stay of 7.
Use the fastboot flash / erase commands, as in this thread:
https://forum.xda-developers.com/showpost.php?p=73119650&postcount=1
If at any stage your phone get bricked, ie, black screen after reboot, no charging, etc. Use these instructions. They saved me in the last week from returning my device for a replacement(and paying $350.00):

Where can I find the stock recovery for XT1650-03 RETEU without downloading an entire ROM zip file?
I have stock 7.0.0 with TWRP and Magisk 13.3.
I want to install the stock recovery so that I can install the 7.1.1 OTA which is available on my device, after which I will flash TWRP and root again. Will this work?

If you didn't take a backup of your stock boot and recovery before, then i think you'll have to go the long way by flashing the whole rom.
If you manage to install the 7.1.1 OTA after that, boot once into TWRP, backup stock recovery & boot and save it on your sdcard/pc. Then you can start flashing TWRP permantly, root, etc
Someone correct me, if I'm wrong.

You must have fully stock. I would suggest that you uninstall Magisk

The reason that I installed Magisk is because after unlocking the bootloader with the stock rom, it would not boot anymore. Installing a custom kernel or Magisk solves that issue.

Okay I uninstalled Magisk which initiated an immediate reboot and resulted in a bootloop just after the bootloader message.
I think the issue occurs because the Data partition gets encrypted when root is uninstalled and decrpyption fails because of a bad key due to the unlocked bootloader.
To recover, I used TWRP to wipe/format the Data partition and then flashed the no_verity zip file from the thread below which disables encryption. I then ran "fastboot continue" after which my phone booted back into Android:
https://forum.xda-developers.com/moto-z/help/bricked-moto-z-unlocking-bootlader-t3634701
My phone status was then: Stock Android 7.0.0, no_verity patch (no encryption), stock recovery, unlocked bootloader.
So my phone is about as close to stock as I can get it with unlocked bootloader.
I finally attempted to install the 7.1.1 OTA again. It reboots and indicates that it is installing and then pops up with a message that says "Error".
Pressing the power and up button brings up the recovery screen with the error log (with info that I don't understand) and from there I can reboot into system again where I get another message indicating that the update failed and no changes were made.
I'm hesitant to install RETBR or other non-RETEU roms (Because although they might work, there probably are some differences such as LTE bands etc. and they are not actually correct for my phone) so I'm not sure how else to get to 7.1.1 unless the wifi issue is resolved with the image that Erfanoabdi uploaded in another thread or Lenovo releases an official 7.1.1 firmware package for the RETEU model.

You still have a modified ROM as you flashed "no_verity patch"
The best for you would be to search for your version of ROM and FASTBOOT FLASH everything back.
Then see if the 7.1.1 OTA wants to stick.

So far I have been unable to find the official RETEU firmware from Adnroid 7.0.0 and I'm hesitant to flash the firmware for another region because it isn't technically correct for my phone and there are likely small differences that might become an issue at a later stage.

So far I have been unable to find the official RETEU firmware from Adnroid 7.0.0 and I'm hesitant to flash the firmware for another region because it isn't technically correct for my phone and there are likely small differences that might become an issue at a later stage. (Maybe the LTE bands are different etc...)

The LTE band on RETEU is 20 and stays 20 with RETBR. No change and everything works. No issues with LTE.
As I mentioned before, the RETBR version is the only working 7.0 backup for RETEU devices. After flashing RETBR , the softwarechannel changed automatically into RETEU. With this, i took the OTA 7.1.1.
Btw. the 7.1.1 OTA doesn't even change the boot loader Nr.( 0x9107). That means, if you mess up with 7.1.1 you can safely downgrade to 7.0 by flashing RETBR (and take a fresh 7.1.1 OTA again)
Did that twice without issues.(for security reason i always skip the two lines with "bootloader" and "gpt" at the top of the flash commands)

I cannot get RSDLite to detect my phone in fastboot mode so I guess I'm going to have to run the fastboot commands manually.
What do you mean about skipping the bootloader and gpt commands? If I skip those, I keep my stock "unlocked bootloader" and "gpt" but then the phone probably won't boot again because that is very much like what I have now except that I flashed the no_verity patch when my phone would not boot.
What exactly are you avoiding by skipping those two lines? Should I skip them too?

It's out of my knowledge if your verity patch influences either bootloader or gpt partition. So i would recommend to flash those two commands in order to "repair" them. If you'll get an error message, skip them and proceed with the rest.
I always prefer RSD method instead of manually flashing by fastboot commands.
Have you installed the latest version of RSD-lite 6.2.4? Have you installed the latest moto drivers?
If you have extracted the RETBR. zip, search for "flashall.xml" file. Open it with a texteditor and you'll find the correct flashing commands.

P20 lite bootloop

So I unlocked bootloader and FRP. Installed magis. It was working, but when i tried to install xposed, it went into a bootloop. Now I'm stuck at eRecovery screen with nothing working. I've done factory reset 10-15 times. Clicking 'Download latest version and recovery' is also not giving anything. Can go to fastboot mode. Went there, saw FRP was locked. Thinking I'll redo the process, I relocked the bootloader. But now the commands aren't working as neither 'allow oem unlock' nor 'usb debugging' is enabled. I can't enable them as phone won't boot up. Any solutions? Please help.

What your build ?
If this phone with OREO or with NOUGAT / Android 8.x or 7.x ?
Possibly didn't work because the rom was of a different built. I've an ANE-AL00 8.0.0.131. Any solutions for this fix? Thanks.

Yes. I flashed same file only. But not booting up. In DC, it says file writing complete when in fastboot mode. But in upgrade mode, it fails at 5/31 PACKAGE_TYPE.
I'm using update.app from update.zip. Is that what I should be using? Should I use the other zip files(cn, public etc.)? Please help.

you write "ANE-AL00 8.0.0.131" - this is not the "full" build : what's your Cxxx ?
on FirmwareFinder i see (example)ANE-AL00C00B133 ( C00 = Country '00'; B133 = Build Counter )
you need the correctly build from your phone !!!
you can boot to bootloader ?
your bootloader is unlockt ?
your FRP is unlock ?
you have download your build FULL-Update ?
you have with UpdateExtractor from Update.app (inside Update.zip)
- ramdisk.img
- recovery_ramdisk.img
- system.img
extracted ? The Extractor do automatic for all *.img a *.img.header.
you have copy this 6 files to your ADB-Folder ?
If this all "YES" then boot to bootloader and
- fastboot flash ramdisk ramdisk.img
- fastboot flash recovery_ramdisk recovery_ramdis.img
- fastboot flash system system.img
reboot phone, phone start to eRecovery and Low-Level format "data" and boot to system.
phone start as "new" phone (initial settings)
good : phone work
no good : all data is lost
AND very important : do not relock the bootloader !
ONLY if bootloader 'unlockt' you can self-repair !

Since bootloader and frp locked, adb commands are not working. Hence I'm using DCPheonix to flash the file. But without luck. It's still botting to eRecovery only
your phone is C675, you flash C00 : no correct
now is inside your phone a 'mix'
i think, you can no self-repair - sorry
@Arseon, my opinion your system partition is a mess due to xposed installation fail.
The solution for this case is restore system partition, it worked for me in the past.
In some cases we can get lucky install a clean system partition even if it is from other region code, because the main differences between regions are located in the other partitions
But what I learning is that system from C00 region don’t follow this standard because at least is missing google apps.
With DCPheonix did with get lucky and flash all files or just the first 4 and stop in the PACKAGE_TYPE?
same situation
I am in the same situation, can only boot to erecovery. I tried boot fastboot flash 4 files (because i have bootloader and frp unlocked) and dc-unlocker without luck. In both cases pass the flash but phone still not boot, only erecovery. I can get twrp works now following this guide: https://forum.xda-developers.com/hu...covery-twrp-3-2-1-0-p20-lite-edition-t3800692 but i dont have backups because i do a factory reset and the internal storage is empty. What can i do in twrp?

In pretty sure you are flashing the wrong firmware, try to push your version with dc-unlocker in fastboot and download the excatly matching firmware. Good luck
well, i have all of this+one more tougher stuff..
Well, I tried to install a custom ROM on my P20 Lite (ane-lx1) via TWRP aand when I failed I ended up into a bootloop, but the thing that got me a headache after a full day of forum research is that when I attempted to install the custom ROM the TWRP wanted a .img file, not a .zip file, so I rebooted after I alreday wiped out everything, I made a backup into the phone, BUT I cant access it because.. the TWRP freezes every time at the TeamWin logo.....the only thing that is accessible now its the fastboot&rescue mode and I'm out of juice and desperated...the bootloader is enabled...i think i preety much killed my phoen and my brain trying to get an android stock experience...i really have to get some sleep,well..thank you for your attention, if you have any suggestions that would pick me up from this mess I would be very greatfull, i'll see what i had left to do as soon as i'm able to...for now, have a good night/day/afternoon, whatever side of the world you're from
Edit:
I left the phone all night into bootloobing and after it got FULLY discharged, I dont know exactly how but the TWRP hasn't popped out, instead after this I was able to get into eRecovery and now it is downloading the 146(C432) version. I guess that I got lucky

ANE-LX1 - Change Vendor/Country Code

Hi folks, I've had a Huawei P20 Lite lying around here for a while. It is a demo device.
I was able to successfully unlock the bootloader with using the Testpoint method.
Now I need help to change the country code from "demo" to "eu" and I also need the right firmware. Is there a free way to change the country code?
I hope you can help me with that ? Thanks in advance.

your firmware is incomplete, it must be 8.0.0.143, if I'm not mistaken. Try again Huru method & factory reset in Stock recovery (not in TWRP!).
Or, download Service ROM Link , unpack , there's dload folder in "Software" . Copy dload folder (without unpacking it) to the OTG flash, turn off the phone and press and hold both volume buttons + Power ( this method will lock the BL again).
Thanks for the files. But i get an

Probably due to incomplete firmware .112 , ( it was stupidity on my part to suggest Service ROM in this case, sorry. Maybe I was too sleepy...).

Okay, idon't think that's relevant anymore anyway
I found the problem. It was the TWRP version. I took the latest one (twrp-3.5.2_9-0-anne.img) and it couldn't mount the /system partition. Now I took a version from this forum (twrp-3.2.1-0.img), which seems to be specially adapted for the Huawei devices. Unfortunately, it doesn't support OTG, but that wasn't a problem because I moved the files it to the internal memory.
Only with this twrp version could HuRUpdater.zip be executed correctly and all other files just like that. Here, too, I was first asked to press the vol-down button.
After the smartphone finally boots properly, I flash the firmware via dload to lock the bootloader again and do over the Recovery Wipe data / factory reset + cach partition.
Now I'm on version 8.0.0.046(0CXB). Unfortunately the device cannot find a new firmware version and nothing can be updated via HiSuit.
Can you tell me which step I have to take now to get the latest Android version for the device?
Thank you very much so far for your help

Unfortunately, you have incomplete FW there again, I think you're doing something wrong. And until the correct FW is there, you won't be able to receive OTA update or update via dload.
If you have followed instructions to the letter , it must work.
Use this TWRP . ( I don't know why you used TWRP 3.5.2.9, in the guide there is a link to 3.2.1-pretoriano80.). 3.5.2.9 isn't fully compatible with our device.
Try this way out:
- Flash TWRP
- Wipe - format data
- Reboot back to TWRP
- Wipe - Advanced wipe - wipe Dalvik/ART, cache, data, system
- Go back and flash HuRu
Note: the installation of the first file (write radio image...) must take longer, 2-3 minutes, this is proof that the installation is proceeding properly.
Btw, have you tried update via eRecovery & Wi-Fi?
Did it exactly like that. And then the 9.1.0.370 (C432) from the same thread loaded (dload / ANE-L01_hw_eu).
Now i have the firmware: ANE-LGRP2-OVS 9.1.0.370 in the device information.
Unfortunately, there is no further update, but I also don't know whether the current one is already the most recent?
What I also notice is that Dual-Sim settings are available in the menus. The IMEI2 is only provided with 000000000000000. I know that my device "only" supports single SIM.
Can I fix that too? Then everything should be fine as far as possible

Oh, it's all clear now
Because this oeminfo is for dual SIM. Oeminfo for single SIM can be found for example here:
https://forum.xda-developers.com/t/c432-single-sim-oeminfo.3873312/
Also update_all_hw.zip file is for ANE-L21, you need ANE-L01, unfortunately, I don't have files for single SIM.

Maybe...You have to downgrade to Oreo via HuRupdater using downloaded files, then install TWRP over eRecovery and install stock Recovery.
Download https://androidhost.ru/2zMw and create dload folder .
In TWRP install new oeminfo.img , then go back to the main TWRP's menu, select Reboot > Power off. Use three buttons kombo to flash service ROM.
To be honest, I've never tried a variation like this, so I'm not responsible for this procedure, but it should work. The question is, is it worth it ...

Which step is missing now exactly? I followed the steps from you. I also used the files from the other thread that you linked. The single-sim / dual-sim problem is not important either. The main thing is that it works that way too

Are you sure? In my opinion, this is your main problem...
Hello, it's been a while. I sat down again and went through everything. The dual SIM files fold onto a single SIM smartphone. I was finally able to install the update via eRecovery after flashing via TWRP. Then two updates were pulled or installed via Android OS. Now I'm on 9.1.0.132 (C432E5R1P7).
