CAUTION
Do not do it if you do not have a clear vision of what you are doing: for inexperienced users it is a way to get a "paperweight", I do not accept any responsibility: you do it at your own risk!
From the post of Ryü[email protected], I share my solution to downgrade for HTC U11 from Pie to Oreo/Nougat
1. Root is required
2. If you want to downgrade to Oreo you need the exact RUU file of your phone. With Nougat, you need the Oreo OTA file and the exact RUU file of your phone. You can search RUU and OTA file in here
3. With the downgrade to Oreo, you need Universal HTC RUU/ROM Decryption Tool
4. ADB and FastBoot tool, download the latest version here
5. HTC DEV Info tool, download here
Now is the step by step guide:
Step 1: How to root?
- If you already rooted, you can go to step 2
- You can root Android 9 with Magisk without TWRP. First, You need to download and install the Magisk Manager.
+ You need file boot.img of version which your phone is running. You can get it by download the OTA file and extract it. Copy it into your phone.
+ You need to download and install the Magisk Manager.
+ After install, open it and choose install => Install => Select and Patch a file => choose your boot.img file => waiting => Magisk will create a file with the name magisk_patched.img
+ Reboot your phone to download mode, flash the patched file => reboot to system => done.Step 2: Change version
+ Open HTC DEV Info tool => click get ADB Devices => Get Device Info => Check your phone to accept root permission for Shell
+ Change version to version of your phone RUU => Save => Apply All ChangesStep 3: Flash hosd_singed.img
+ If your RUU is Android 8, using Universal HTC RUU/ROM Decryption Tool to decrypt and copy hosd_singed.img file to ADB folder
+ If your RUU is Android 7, open the OTA file with WinRAR and extract the hosd_singed.img file to ADB folder
+ Reboot your phone to the bootloader.
+ Open cmd, type fastboot flash hosd hosd_signed.img and press enterStep 4: Flash your RUU
+ If your RUU is a ZIP file, you can copy it to the memory card and reboot to download mode to flash it
+ If your RUU is EXE file, you can flash it from your computer
"
2. If you want to downgrade to Oreo you need the exact RUU file of your phone. With Nougat, you need the Oreo OTA file and the exact RUU file of your phone. You can search RUU and OTA file in here
3. With the downgrade to Oreo, you need Universal HTC RUU/ROM Decryption Tool"

Sorry for reviving such and old thread but im trying to do this, pie to nougat, but i cant seem to find the correct hosd to flash, flashing the nougat ruu's hosd (Versions 1.x) gives an error when i try to flash any ruu about battery low, My CID is 622, could you check this thread? https://forum.xda-developers.com/t/wifi-not-working-cant-downgrade.4366063/
EDIT: NVM, i used the OTA hosd and that did it using aruwizard and the nougat rom. It clearly says to use the OTA one but im a dumbass.

Ok then, i think I have found the hosd.img anyway.
But now my problem is, which one is supossed to be the nougat ruu I should use? any of them does it?
I mean, what does he mean when he says "the exact RUU file of your phone"? The nougat ruu? The pie ruu? or what?
And why you would need to have root anyway?

1). Well Friends will try to analyze here the procedure followed to make "root" the mobile without the Chinese "Root Explorer" and with all the rest to function properly after the procedure the "Root".
2). Now you must download the "boot image" from here: http://www.megaupload.com/?d=HA9FSEKL and then
let's desktop Pc.
3). Basic: Before you start anything you have to BE CAREFUL, if you have not already deleted the file "dload" from the sd card!
5). It would ultimately be taken out and the sd (as I did) Did the end of the process when boot read anything and
the Chinese"root explorer" fly again ... so for sure.
================================================== ========== =============================
Follow the letter the instructions below:
1. Boot the phone into the pink screen mode (volup + voldown + power) and connect it to the PC via usb cable.
2. Your PC will find a new device. Open it, and then open folder called "image" in it.
3. Copy stock boot.img to your PC, you'll need it later.
4. Now copy my boot.img from PC to the device, replacing stock boot.img
5. Use your operating system tools to safely remove the device, then pull out the battery to get out from pink screen mode. Boot the phone.
6. While booting, the phone gets rooted. When it boots up, you can turn it off and get to the pink screen again.
7. Restore stock boot.img you saved earlier.
8. Boot the phone again - it is rooted and working properly now
================================================== ========== ===============================
Before reinsert the sd it would with a cardreader to put in Pc and delete folders: android_secure,, Android.
And so the bags otherwise they'll rebuild automatically once you put the sd.
If you do everything correctly you will have 2.3.5 rooted, without Chinese"root explorer" and the witget weather-clock its ok.
Please also stated that I have not started again after the root "Root Explorer" from the Market ONLY use another program.(optional)
================================================== ================================== ==========

the fixed "boot.img" download: http://www.megaupload.com/?d=HA9FSEKL
It doesn't install root explorer, and it doesnt delete cust.img, but still should give you root access. To have the clock widget just put cust.img I've uploaded earlier into image folder from pink screen mode
Hey guys! I won't fix my boot.img.
It will work that way
you put my boot.img into image folder via pink screen,
boot phone once,
then boot into pink screen again,
restore stock boot.img and that's all
the phone is rooted and no overhead at start because of those modified boot.img's.

so we can just install chinese and then somehow navigate to settings menu and choose english?
can we have a screenshot please?
Anyway I believe that it is not serious that huawei doesn´t release the chinese and overseas versions at the same time.
Well this is interesting.. the system image has the wifi driver for the regular U8800 in it.
system dump for those that want it: http://www.multiupload.com/1AG300FSXD
DEV ONLY. It's not in CWR flashable format.

Also the kernel boots with your MIUI port. A few issues like rather broken screen rotation but that'll be a simple fix.
Roll on the release of the source.
I was gonna say that the kconfig looked like it had support for the regular u8800.
How did you split the kernel from the update btw?

When flashing my smartphone I get an error (S_DA_EMMC_FLASH_NOT_FOUND)
Can I copy the scatter.txt from RC5 to whichever ROM i want as long as it is for the same phone? Basically I have the RC5 but I experienced that the battery is horrible so I wanted to try a different newer OS. Somehow there is an error installing via TWRP the other roms I have in zip but flashtool works fine. These files do not have a scatter-file though.
Thank`s for the instructions
I will thank for the instruction, because I breaked my phone while trying to flash madOS 8.1.0 (update from april). Before my Jiayu S3 basic (16 GB, 2 GB) worked fine with madOS 8.1 from 2017-12-30. I surely made a big mistake, therefore the phone was dead - no reaction any more.
I found this solution to flash back the stock rom 5.1.1 with twrp. Phone is alive and works.
I think, I have done a big mistake, because all trials to flash madOS 8.1 from april ended with boot into TWRP. I tried flashing to madOS for a long time, isn`t possible any more. Maybe also my old phone has a failure.
Therefore I have to thank for Your excellent work. Thanks.
Hi!
I'm trying to flash my S3Adv. (3GB RAM, Kitkat, TWRP 2.8.4.0) with madOS_8.1.0_s3_h560_20180422.zip, but, the "Zip signature verification failed". Before, the MD5 sum is checked and matches. I also checked the file with "zip -T" on my Linux machine and it reports "OK". When the "Zip file signature verification" is turned off, TWRP reports "error executing updater binary in zip ..." What's going wrong? Anybody here who can help?
Thanks in advance
Frank
Nearby: I wiped system, dalvik, cache and data.
Solution:
- Install Flash Tool
- Flash Android 5.1.1 (RC5_S3_16GB.zip)
- Start 5.1.1 to do a basic configuration
- Boot into TWRP recovery which was included in RC5
- Install twrp_20180417.img
- Boot into TWRP recovery
- Install madOS_8.1.0_s3_h560_20180422.zip
(a full wipe is, may be, necessary, but, I don't know, when the full wipe should be done within my procedure - I did it earlier)
I am done follow link it work.
You can flash update EMUI-5.1 zip now,if you firmware on C432B182/C567B190.
I am rebrand form C636 to C567 for flash update EMUI 5.1.zip

EMUI 5.1 beta, Android 7 english Security Patch 5.5.2017 Update; 14.05 17:00 25
So you love it is as far as EMUI 5.1 in the beta version. Here you get a taste for the things that come to us, also app technically, there are great and useful programs with it
Download the changed HWOTA here
Download the EMUI-5.1 zip
Unpack the EMUI-5.1.zip and the HWOTA on your system
The 4 apps, the emui.zip and the gps.conf please copy to the SD card
Copies the update_data_public.zip and the update_all_hw.zip from the folder hwota / update to the sd-card which are then needed for root.
Please copy the system.img into your fastboot folder
Please make a backup via HW Backup
1. Installs the stock Rome from the HWOTA folder as described in the first thread. After a reboot your phone routs again (please respect before the boot loader to see if the OEM unlocking is switched on)
uses the instructions for root from the first thread.
2. Your mobile has now root, now installs a file manager (I recommend the root explorer) because the next step, the Explorer, the data backup the Google Apps including the playstore do not omit this step.
3. At this point, make the first TWRP backup if there are problems with beta. Make backup without pin, password or fingerprint, important.
4th Starts in TWRP and give the following command a fastboot flash system.img the system is now overwritten with everything Emui 5.1 is. After a reboot you can now the 4 apps you at the very beginning on your ext. Sd-card copied install (file manager, backup, playstore and optional market).
5. now you can make the second backup in the TWRP with me it is Stock-Rom-2
6. The gps.conf with a root Exlorer after root / system / etc copy then the authorization to rw-rr or octal 0604, So it works
7. now you can falshen the emui.zip in the TWRP. Then you have again a bunch of new programs, what you need of it you decide for yourself.
A useful tool I introduce shortly before, It is called children's mode, but could also be called women's mode, why very much in the picture, simply read.
Note: the Android security patch is from May 5, but it will be shown on April 5 because the default is from the build.prop in the vendor directory. If you change something there the developer options no longer so please finger wech of the build.props.
Important, always disable the pin and finger scan before any backup or installation.
But first the links:
HWOTA MEGA
EMUI 5.1 MEGA
If there should be problems with the beta, here is a system.img based on B190 final with security patch May 2017. As usual in the fastboot folder copy and in fastboot mode with fastboot flash system system. Img install.
B190 MEGA

Is not very clear.
Can anybody list which are the improvements expected for 5.1?
I am recommend base rom c432b182 work for flash emui 5.1 beta more than c567.
If your base rom is c432b182 ,you canload 1 file (emui 5.1) for flash emui5.1 .
If your base rom on c567b190 ,you must load 2 file (emui 5.1+b190(system.img)).
Strange, I thought all EMUI 5.1 Firmwares were supposed to start with 3**?
I though EMUI 5.1 Beta Firmwares were port from P10.
But base Firmware last update of MATE 9 is B18X-B213.
EMUI 5.1 Full will comming soon next july.
If anybody use S.H.I.E.L.D.-Rom V1.1 or other rom base C432B182 ,you can flash system.img & flash EMUI 5.1 .

No PC needed, no MSM no cables , it is OTA flash!
FIXED the phone by flashing rollback package, as described:
W A R N I N G ! ! ! THIS ROLLBACK PACKAGE WILL FORMAT INTERNAL STORAGE - BACKUP YOUR FILES ! ! !
1.download it (if mods remove the link PM me) https://oxygenos.oneplus.net/OnePlu...all_2105112238_downgrade_708a3306f3904ad4.zip
2.file will be downloaded as .JAR, not sure why! rename the file from xxxxxxxxx.zip.jar to xxxxxxxx.zip (simply remove the jar extension)
3.move the file from folder Download to root internal storage on the phone
4.go to Settings/System/System updates
tap on top right corner and choose Local Update - then you should see the downloaded .zip , choose it and you will be rolled back to 10.3 as brand new phone.
Result: Battery hold up great!

I think there is rollback packages from oos11 open beta,
Not sure if it can work on stable.
You should look it out.

I'm glad it worked well for you.
Need to find posts on future fixes on that matter.
we want OOS11 (It's cool) but with normal battery.
Most threads are really old, so I am starting a new one.
And one of better ones was just locked and deleted
I have Xperia Z2 D6503 with locked bootloader.
Sadly at this moment pretty much every single thread you find is 5+ years old and most links are dead.
You can find those files online but question is are those same files you need.
You might download the wrong file with same name.
So I will either update the links if I find the files or I will link the best root method if any at this present time.
And if you have any files or info to share, do so here.
So far,as of creation of this thread, nothing is available.
Ok so I will just update you with news.
I found everything I wanted from Russian folks at 4pda, simply put, once again Russians come trough when no one else could.
Spoiler: My rant
Funny thing, I always knew I should learn Russian and German, for doing things no one else can and fixing stuff, those two places/nations are simply THE best.
LIterally every time I needed something I found it on a Russian website, and every time I needed to fix something, some cool German helped out.
I am attaching the archive with all files needed to root the Xperia Z2 with locked bootloader, with instructions inside, do this at your own risk as usual.
Btw since I plan to host these files forever they should be available at all times as long as these hosts dont remove em.
Please dont contact me if they don't work, I only keep them there, I dont have them on my PC

I would like to document my little journey here for anyone who might need help.
So first flashed the stock firmware by downloading it via XperiFirm+5.6.2+(by+Igor+Eisberg)
But that tool only downloads "File" files, it downloaded 4 of them, but you need only one FTF file.
So I used FlashTool 0.9.34.0(also called Sony Mobile Flasher by Androxyde), it has a tool, Tools > Bundles > FILESET decrypt and by following the Youtube video I used that tool to create the FTF file I needed but for some reason the FlashTool put that FTF file in C:\Users\USERNAME\.flashTool\firmwares
I also needed to install the the drivers for my phone as well as fastboot drivers, this is covered in the original guide that I included in the archive above.
Steps 7,9 and 10.
Btw sorry if I skip something I did, you can fill in the gaps, I'm sure.
Anyways after FlashTool detected my device I flashed the stock firmware(23.5.A.1.291).
Then comes the moment of rooting.
So all the drivers are installed, files are there and nicely organizd, I am ready.
I opened both guides, the original one and Russian one translated to English.
Turned out both added up together to create the ultimate guide, I will explain why in a minute.
-Put the files on SD, check;
-Rename the 575 kernel files extension to .TFT , check;
-Turn off the phone, check;
-FlashTool is opened and waiting,check;
-At this moment I actually clicked on lightning bolt icon, then I clicked Flashmode and then under Source folder I located the folder where 575.tft kernel file is located.
Then I selected THE FOLDER
After that under Firmwares, the 575 kernel shows up and I go trough drop down arrows to click on it 23.5.A.0.575.
Then I click on kernel.sin in Content section.
Then under Device filter I double click and find Xperia Z2;
-At this point I slide the Firmware Selector window to the right and I don't close it, so I can see the console and what Flashtool is reporting, the console would be the part where Flashtool is writing something, all that text under those big icons(lightning bolt,BLU,lock,key..)
-After that I hold the volume down and connect the USB cable to the phone
And I notice Flashtool tells me phone is connected in flashmode
-I click Flash in the Firmware Selector window that was still open
-It does its thing and reports success.
-I disconnect the phone and close the Flashtool as Russian instructions also recommend it, dont skip this
-I turn on the phone, all boots fine and I do check the kernel by opening the service menu(dial *#*#7378423#*#* and find Service info, first line Phone software version at the end theres .575)
Actually at this point I had minor ****pants moment, Service menu wouldn't open instantly, took about 20 seconds
-Then I proceeded to flash the recovery
But here I ran into the problem, error adb server version (40) doesn't match this client (36)
That is because 3 files inside Recovery_for_MM575-291>files folder, named
adb.exe , AdbWinApi.dll , AdbWinUsbApi.dll
need to be replaced with version 40.
So I browsed online and downloaded platform-tools_r28.0.2-windows
Here is where you can find more versions
adb-win/SDK_Platform-Tools_for_Windows at master · awake558/adb-win
adb.exe fastboot.exe. Contribute to awake558/adb-win development by creating an account on GitHub.
github.com
Theres a readme that tells you what file is what version.
So I extracted the archive and inside the platform-tools folder I found the 3 files, copied them and replaced those files I mentioned earlier located in Recovery_for_MM575-291>files .
-After that I run the install.bat without admin right actually and it all goes smooth.
-Instantly phone rebooted into recovery which made me smile
Also I pressed any key to continue and that closed the install.bat window that opened earlier on the computer.
-Then I installed SuperSU, no problem there.
-I press the arrow to go back,
-And find and finally install 291 kernel.
-After that I click reboot button
-Phone reboots without any issues.
Boom, rooted.
Hope and wish you all the best with rooting yours.
According to my experience and reanalyzing current status, I could give this as a permanent order for moving from Locked Bootloader to having a Magisk rooted ROM.
(Any error might be corrected, if an explanation is given.)
1) Flashtool's Flashmode
Flash D6503_23.5.A.0.575_kernel.ftf (which includes loader.sin and kernel.sin)
2) Backup TA partition with backupTA_v2 by Jens Andersen (XDA: rayman, Twitter: @droidray, GitHub: EnJens)
3) Reset to factory defaults
4) Unlock Bootloader
https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/
5) Flashtool's Flashmode
Flash D6503_23.5.A.0.575_kernel.ftf (which includes loader.sin and kernel.sin) again
6) Change recovery with (NEW)_Recovery_for_MM575-291v5 by executing its install.bat
Stay on Stock ROM:
Booting into TWRP
7) Flash root (SuperSU only)
UPDATE-SuperSU-v2.76-20160630161323.zip
8) Flash Z2_23.5.A.1.291_Marshmallow_Kernel_Flasher.zip by moman2000
Change to LineageOS:
7) Wipe cache, dalvik cache, data and system
8) Format data (for encryption removal)
9) Reboot into Fastboot mode
TWRP - Reboot to Bootloader
Flashtool - Fastboot mode
ADB - adb reboot bootloader
Volume down + Power on
10) Flash new kernel extracted from LineageOS
fastboot flash boot boot.img (fastboot flash:raw boot boot.img)
11) Flash new TWRP (twrp-3.3.1-sirius-20200221.img)
fastboot flash recovery recovery.img
12) Reboot into recovery for verification (Failsafe)
fastboot boot recovery.img
13) TWRP
Flash ROM
Flash Magisk
14) TWRP or as Magisk module
Install GApps or microG
change to ftf not tft!!!!
