[Q] why aren't there any Roma for our A9 ? - HTC One A9

Besides the Cm (that has very low sound) why aren't there Roms for the A9 ?

This a copy/paste from somewhere in this forum, but I think its due to these reasons:
With the A9 (and the M9 prior to it), HTC has moved to a block-based OTA system. This means that even mounting system as read-write (as TWRP typically does during startup checks) will nullify the device's ability to take an OTA. Any other changes to the system partition will also cause an OTA to fail (even if that check is removed from the OTA zip) due to "unexpected contents."
Since the A9 has dm-verity enabled and forces encryption by default, root can only be achieved using the new "systemless" root methods. There are two currently working methods:
seSuperuser (this requires flashing only flashing a zip and installing an app from the Play Store)
SuperSU (automatically disables forced encryption & dm-verity, but requires a "Format Data" in TWRP)
There is also no way to take an OTA after you root. However, prior to rooting, you can take a fully untouched system image backup with TWRP, which can be used to restore a fully stock system to the device in order to take an OTA.
How do I backup stock recovery prior to flashing TWRP?
You can't. The "fastboot boot" command appears to be disabled on the A9's ABOOT, so TWRP must be fastboot flashed over stock recovery. The firmware zip included in the OTA will include a usable stock recovery image. That can be extracted and flashed after stock system is restored so that the OTA can be applied.
How do I restore stock system so that I can accept an OTA?
Check the "Mount system as read-only" box in the Mount menu.
Restore stock "System Image" backup (This will only work if you've made a System Image backup prior to making any modifications to /system).
Fastboot flash stock recovery (fastboot flash recovery recovery_signed.img)
NOTE: It is also possible to restore stock recovery via the TWRP GUI. Rename the stock recovery file to "recovery.emmc.win" and place in the backup folder with the stock system image. Recovery will then show as a restore option. MAKE SURE YOU REALLY WANT TO DO THIS, AS TWRP WILL BE GONE WHEN YOU REBOOT OUT OF RECOVERY!!
Reboot to system, install OTA.
What if I have an RUU? Do I need to worry about all this OTA nonsense?
Not if you don't care about losing all your data. If you're S-ON and have an RUU available for your exact variant (model ID and CID must match) and software number (main version must be the same or newer), then you can get back to a fully stock state by relocking (fastboot oem lock) and flashing an RUU. However, if you'd prefer to take an OTA to keep your data intact, the method stated above is how to do so. Or, you can just run a custom ROM and wait for your ROM chef to update their ROM to the latest software (though you'll still have to find a way to update your firmware if you're not S-OFF)
After I go through all this and successfully apply an OTA, how do I make sure I have a clean starting point again?
After the OTA is applied and TWRP is flashed, it will once again detect an untouched system, which will mount system read-only and allow you to make a fully stock backup and start the process over again, this time with the new base.

I think maybe it's because most of the devs have the m9 and are waiting for the M10 or whatever its called, the nexus also requires systemless root etc but has plenty of roms because lots of devs have purchased one, big question for me now that these devs know htc are making the new nexus is how popular the M10 will be?

How do I safely root and unlock bootloader on Marshmallow?

My device is European L04, currently running North Africa release (the earliest Marshmallow build uploaded) - L04_2016_0316_0900 (B820)
I'd like to unlock the bootloader and root my Honor 6. I've never done it (on this particular device), because I've read enough here to know it's slightly more risky than on other devices, especially when you plan to update the stock rom soon, so I preferred to wait until I have the last important update the device is likely to receive - Android 6.0.
What I want to know (some of the answers are in the topics which I listed below):
MultiTool - I've seen reports of bricks when using MultiTool with EMUI4/Marshmallow - why does it happen? My understanding is that MultiTool is a bundle of adb/fastboot and some recovery images for older Android versions, so my theory is that instead of using MultiTool, I should simply get the proper recovery for Marshmallow and flash it manually with fastboot, right?
unlocking bootloader, rooting, flashing recovery - I think I understand the process; in a nutshell: 'fastboot oem unlock X', 'fastboot flash recovery imagename.img', then flash the proper SU.zip in recovery. Where do I find the code, the Marshmallow recovery image, the SU.zip file?
will recovery backup in TWRP work without any problems?
what is the procedure to go back to stock completely after rooting? Unroot, (then wipe if it's needed?) so I am able to safely flash stock firmware again (since, from what I know, flashing stock on a rooted phone makes itself brick permanently, right? or is it just a soft-brick and it can be fixed?)
is there anything else I should know before proceeding?
What I found so far:
http://forum.xda-developers.com/showpost.php?p=66615082&postcount=502 - two recovery images, TWRP and another one (stock?) for the Marshmallow release
http://forum.xda-developers.com/honor-6/general/honor6-multi-tool-t2963060/page50 some rooting instructions for the L02 beta, see posts 494 and 498; no idea whether this is applicable to final Marshmallow or L04 at all
http://forum.xda-developers.com/honor-6/general/huawei-honor-6-plus-unlock-bootloader-id-t3357259 an app to get the unlock code, seems a bit shady to me though on the first glance
http://forum.xda-developers.com/honor-6/development/honor-6-rooting-method-t2962795 alternate methods for bootloader (through a website or by email), in case the app won't work; also, detailed instructions on unlocking and rooting
Basically, I need to know whether my procedure is more or less right before I proceed. I think the information is quite hard to find and the risks are quite high, so I'd like to make a promise - when I'm done rooting it and I know the correct process, I'm going to make a "Update to Marshmallow, unlock, root" how-to thread for all the people that will need it in the future.
Another two questions...
1. Where do I get proper SuperSU for Marshmallow? I get a boot loop (yeah, I know I have to wait and I did, but it's a pretty obvious bootloop from watching the logcat content, and nothing new happens...) after flashing http://download.chainfire.eu/supersu-stable (2.65).
2. I have unlocked my bootloader and installed TWRP, so recovery and fastboot are functional. I didn't make a backup before flashing the zip and now I'm in a bootloop. How do I restore working Marshmallow? I assume I can either beg somebody to upload a TWRP backup for my H60-L04, or somehow flash the stock over what I have now. Can I simply use manual update from SD? Can I somehow flash Marshmallow again with fastboot? I'm too scared of bricking my device right now so I guess I'll brace myself for a few days without a phone until somebody helps me :/
I just flashed the Marshmallow release I had before the bootloop (I used Huawei Update Extractor and flashed boot, cust, system and recovery with fastboot; then open up Huawei recovery and factory reset for good measure, I'm not sure it was even needed) and the device is working. I'll restore my stuff, install TWRP, make a backup then try out your ZIP. Thanks
edit: thanks again - your zip works indeed. So after the initial hurdles, now I've got working root and a reasonable way of restoring in case I screw something up along the way.
Before making a new topic with the tutorial I have a few more questions.
First of all, why exactly we weren't supposed to update the rooted devices? I'm not currently interested in OTAs (it's pretty obvious that it needs a functional Huawei recovery, and you need to unroot cause an update can make a mess in a rooted system, making it bootloop for example), but can we flash extracted images with fastboot on rooted devices? Logically, we should be able to... How about sdcard update method?
Can we flash Marshmallow on Kitkat? (fastboot, sdcard, local update methods?) Or do we need to update to Lollipop along the way?
Can I flash stock roms in general (evenbetween different Android versions) by using fastboot with {boot, cust, recovery, system} images only? There's a lot of images that you can extract with Huawei Update Extractor - why there's so many if they're not needed?

Moto X Pure Edition XT1575 -- systemless root -- OTA updates fail

TWRP 3.0.2-0
SuperSu Pro 2.78
Android 6.0 Marshmallow build MPH24.49-18
I have systemless rooted my phone as per the instructions at http://forum.xda-developers.com/mot...t-moto-x-style-xt1572-br-marshmallow-t3259380
although, it didn't work without some tweaking... Unfortunately I don't remember what steps I took to get it working.
I am not sure of the process form here. Now that I have root, am I supposed to flash boot_orig.img permanently or just when I want to update?
I have tried:
fastboot flash boot boot_orig.img
but I loose wifi and can't download.
I have tried letting the OTA fail with the boot.img flashed, then reflashed with boot_orig.img and tried to install the update zip file via TWRP, but that fails.
I made a TWRP backup before I started rooting and for every major step after that, so I can start fresh if need be.
[EDIT]
I noticed on this thread, http://forum.xda-developers.com/showpost.php?p=63197935&postcount=2 , the following comment:
You must absolutely re-flash your stock /system partition, or the separate root instances will interfere with each other. The installer for this experiment will not clean up old root files.
- Flash stock /system (and /vendor and /oem, if present)
- Flash the attached boot image
- Flash the attached SuperSU ZIP in TWRP

Could this be the problem? If so, How do I "flash stock /system (and /vendor and /oem, if present)"?
Any help appreciated...

[Guide] XT1575 Update To NPH25.200-22 Nougat After Modifying Your System & Re-Root

[Guide] XT1575 Update To NPH25.200-22 Nougat After Modifying Your System & Re-Root
THIS GUIDE IS NOW DEPRECATED. THERE IS NO NEED ANYMORE TO GO THROUGH THE UPDATING PROCESS AS THERE IS A FULL NOUGAT FACTORY IMAGE AVAILABLE (Build NPH25.200-22). FIRMWARE AVAILABLE HERE: https://forum.xda-developers.com/moto-x-style/general/xt1575-moto-x-pure-edition-factory-t3704142 BE SURE TO THANK @acejavelin FOR TRACKING DOWN THE FIRMWARE PACKAGE FOR US.
Notes:
-YOU ATTEMPT THIS AT YOUR OWN RISK IF YOU FLASHED ANY FIRMWARE PREVIOUSLY NOT FOR THE XT1575 US VERSION
-This guide will have 2 parts. 1 for those that kept their systems read only/systemless, and 1 for those that did not.
-Whether you live booted TWRP or Installed TWRP, if you chose to allow system modifications your OTA will likely fail (you'll need part 2).
-Restoring a TWRP backup will not work and will cause an OTA to fail due to having to allow system write access in TWRP - You Need Part 2.
-This guide assumes you have basic ADB knowledge and already know what fastboot is and how it works.
-Thanks to @gokart2 for the OTA and @acejavelin for the return to stock guides
Part 1: Those That Tweaked Systemlessly Currently On 24.49-18-16 (Will only work if you kept TWRP read only/used systemless root):
1: Disable & Remove systemless Xposed within Magisk Manager and all other Magisk modules. Reboot and wait for Art cache to rebuild.
2: Remove any adblock hosts within your adblock app if installed, or any other root level system altering apps like Greenify (don't worry, you'll get them back).
3: Remove Magisk by booting into TWRP and flashing the current Magisk Removal zip. Reboot.
4: For systemless SuperSu you need to consult their thread as I do not use it. (I'll update this if someone knows the correct process).
5: ADB reboot bootloader and fastboot flash the stock recovery. Latest MM recovery links at the bottom of this post. (rename file to recovery.img).
6: Move the OTA Blur_Version.24.231.16.clark_retus.retus.en.US.zip to the root of your internal sd card (NOT in a folder). File links at the bottom of the post. Thanks @gokart2
7: ADB reboot recovery, when "no command" is listed, hold power + tap volume up then release to access recovery options. Choose "apply update from phone storage". Choose the file and wait for the flash. It's a large update so be patient (about 10-20min). Choose reboot manually in recovery after flash succeeds. Enjoy Nougat!
8: For root you can go ahead and flash TWRP again or live boot TWRP (fastboot boot twrp.img) and then flash Magisk 14.0 from TWRP. Works perfectly.
Part 2: Those That Have Done Everything - TWRP Write Access, Custom Roms, On Older Firmware, Etc (XT1572 Build Flashers Do This At Their Own Risk):
1: Flash the latest full factory image available (24.49-18-8) available here: https://forum.xda-developers.com/mo...de-return-to-stock-relock-bootloader-t3489110. Thank @acejavelin for the thread while your at it. Follow the directions in that guide, it's well detailed and accurate - however read my notes just below first:
NOTES:
-Omit the "fastboot oem lock begin" & "fastboot oem lock" commands to remain bootloader unlocked.
-Omit the "fastboot erase userdata" command if you want to dirty flash and keep all of your data. I recommend clean, you can always root & restore each apps data with Titanium after the Playstore installs everything.
-The "fastboot oem fb_mode_set" instead of "fastboot oem lock begin" & "fastboot oem fb_mode_clear" instead of "fastboot oem lock" I've found to be unnecessary if staying unlocked. Your choice.
-The "fastboot flash partition gpt.bin" & "fastboot flash bootloader bootloader.img" commands will likely fail due to version mismatches. This is ok.
-The "fastboot flash modem NON-HLOS.bin" tends to fail too. For this, just run the command again until it succeeds.
2: After flashing 24.49-18-8 take the OTA to 24.49-18-16. Reboot. OTA zip provided below if you prefer to sideload.
3: Either install the 7.0 OTA the normal way via the update center or just side load it using the directions above. I recommend side loading due to the file size being very close to 1GB.
4: For root you can go ahead and flash TWRP again or live boot TWRP (fastboot boot twrp.img) and then flash Magisk 14.0 from TWRP. Works perfectly!

Alrighty. I got back to stock 6.0 with the 18-16 update. I couldn't get the OTA via the system update, so I tried doing it via ADB. That threw up a "status 7 error". I then copied the file to my internal storage and selected update via SD Card in recovery. It hung on "Patching System Files" for a while, but in the end it moved on and worked fine. Thanks for the awesome guide!
Thread updated with downloads for the 24.49-18-8 OTA to 24.49-18-16 zip.
I exctracted the 7.0 Stock recovery to replace if you decide to flash TWRP and want to go back to the stock recovery for future updates (HAHAHA yeah right!). Download link in OP. The 7.0 Recovery is different than the MM recovery. They are not interchangeable. Don't flash the 7.0 recovery on MM.
Question... can those of us who are rooted, custom roms, with TWRP, not just flash a stock unrooted TWRP backup from here: https://forum.xda-developers.com/moto-x-style/development/pure-firmware-tuff-wip-t3224833
Then, flash the stock recovery like it says... and take the update? Isn't that easier than this method?

It probably won't work. Once TWRP is given write access to your system (which is required to flash a full rom or restore a backup) any OTA's will fail. Plus any modem/bluetooth mismatches will cause a failure too. Fastboot flashing a stock image is really very easy & pretty much a guarantee that everything will work properly. However, if your able to get it to work, please let us know...though I don't think it will.

Once I do this, I can just reinstall TWRP and Magisk, backup the stock 7.0 and if I ever decided, just flash a custom rom later on?
hey thanks for the help on this one. I was so worried because I got stuck on th May security update OTA-wise.
question: I messed with the LatAm version of Nougat, so when I tried to re-lock the bootloader, it game the preflash error.
After this proper update flash, is there a way to run the bootloader CMD to just re-lock the bootloader?
Here's the recovery before the 7.0 one, just incase.. Was bored. Ok, I won't lie....didn't see u posted the 7.0 recovery....lol.:good::highfive:

What is everyone's fascination with relocking the bootloader? You do not need to relock your bootloader. You cannot relock the bootloader unless all your system partitions match. Use my part 2 section. Read the notes, skip the bootloader lock commands. Leave your bootloader unlocked, get up and running on nougat, then you can issue the lock commands if you really want a locked bootloader.
How exactly do you flash the 24.49-18-16 OTA? I'm stuck at this part

Copy the file to the root of your internal storage. Reboot into recovery. Hold power = volume up & release to access menu options. Choose apply update from storage. Select the OTA.zip package and let it install. (Directions are clearly written in OP.)
Does it matter which version you're on? I'm currently on MPSH24.49-18-4 with the May 2016 security update.

Part 1 implies that you are on MPSH24.49-18-16 (dec), for part 2 - no it doesn't matter. Go ahead and start with the full firmware available MPSH24.49-18-8 and follow the steps from there.

Root is completely up to you. It's noted so users know that TWRP/Root are working. My logic with any XDA thread is that your bootloader is unlocked and you want root, but that's me...

I am running Dirty Unicorns right now and when i looked up what I'm on in fastboot, it showed MPSH24.49-18-16. Would I just follow part 2 and use MPSH24.49-18-8 or something? I thought I had to use at least the version I'm on or newer.

Your issue is that TWRP has modified your
System, any restoring of the stock rom will fail to update. So yes, you'll need to go through part 2 and downgrade and work your way back up.

I downloaded the zip (it took a while).
Restored to stock like 3 different ways but still hit a road block. I went the adb sideload route but got status error 7 because my build fingerprint wasn't correct. I tried searching for the right build I need, but I'm not an expert and couldn't find the right set of files that I was sure I knew how to restore. I ended up restoring my AICP backup.
If somebody could PM me and give me a hand (messaging through Hangouts or something) that would be AWESOME!
I'm planning trying to snag an XL 2 pre-order next week, but until then the less headache the better! Plus stock Nougat looks better on a Swappa listing
Trying to sideload via recovery 24.49-18-16 but I keep getting "("unexpected contents:EMMC:/dev/block/bootdevice/by-name/boot...". I've also tried installing from the phone but the same error appears in recovery. Any ideas?

Custom ROM

Hello, will it be possible to return from custom firmware to the original one and continue to receive OTA update ?

Yes, if you used TWRP to create a backup of your stock ROM before you flashed a custom ROM, you just use TWRP to restore the backup of stock ROM.
Or, if you didn't use TWRP to backup your stock ROM, you can flash your device's stock firmware using the flashtool designed to be used with devices made by your device's manufacturer.
But to install TWRP you need Root, and if you get it, then OTA updates stop coming or am I wrong?

No, installing TWRP does not require root. Yes, TWRP and root prevent the installation of OTA updates.
That is, to make a backup copy of the original firmware, you need TWRP, but if you install it, you lose the ability to receive OTA updates, and if you restore the original after the custom firmware, there will be no updates? Or can TWRP be removed and OTA updates will come again? I'm sorry I do not understand.

To be more specific, installing TWRP does not necessarily prevent a device from actually receiving/downloading OTA updates, it prevents the actual installation of OTA updates because part of the OTA update includes automatically booting into stock recovery to apply the update. If you have TWRP installed, the OTA update can possibly be downloaded to the device but when the device automatically tries to reboot into recovery, it is trying to boot into stock recovery but if you have TWRP installed, it can't boot into stock recovery to apply the update and when it tries to boot into TWRP, it will try to apply the update but it will fail, resulting in a bricked device and the device will have to be restored.
When it comes to OTA updates, all that is required is an unmodified stock system partition(meaning, no root or any other kind of modifications to the system partition), stock recovery(meaning, no TWRP) and the update has to be offered by your carrier if they offer the update for your specific device.
If a device is rooted, has other system modifications and/or has TWRP installed and you want to apply a stock OTA update, you have to remove root and any other system modifications and you must replace TWRP with the original stock recovery before you can apply the update. If you have TWRP and or root and you remove them to apply an OTA update, you can root the device again and install TWRP again after the update, provided that the OTA does not come with a locked bootloader that can not be unlocked, in this case, you will not be able to reinstall TWRP or root because the bootloader will be locked, which prevents you from installing TWRP again. Sometimes, users remove root and TWRP to apply OTA updates with the intention of rooting and/or installing TWRP again after the update but then get stuck in a position where they can no longer root the device or install TWRP because the bootloader gets locked during the update and there is no way to unlock the newly updated bootloader, from then on, they are stuck with stock with no way to get root, TWRP and custom ROMs reapplied to the device because they were not aware that the update came with a locked bootloader that can not be unlocked by any means.

Flashing stock recovery only

Hi there, I'm having no luck finding a solution to my problem anywhere.
I'm using a Galaxy S7 running Oreo (I know, old school), and like many phones, it came with a bunch of apps that can't be uninstalled unless you have root access. So, I installed TWRP, and then Magisk v23, and then I installed a root uninstaller in order to remove the apps in question.
However, I use Revolut and an app for the bank I'm with, and so while my device is rooted, I am locked out of both.
What I want is to have the disable-only apps gone, and my device unrooted and back to normal so I can use Revolut and said banking app.
I believe uninstalling Magisk should unroot the device, but without Magisk installed, I can't boot into the system because of TWRP and the whole dm-verity thing. So, I want to replace TWRP with the stock recovery, which, if I'm correct, should achieve the desired outcome.
I downloaded the exact firmware for my phone from sammobile, and the recovery file can be extracted from it easily, but I don't really know how to go about flashing said file, or even if I can. Odin isn't working for me.
I tried flashing the whole "AP" file via Odin (the latest version), but that restored the device back to it's factory state, disable-only apps and all.
So can anyone help me with this? Or is what I want to do here even possible? I'd really appreciate some input / advice. Thanks!
P.S. maybe you can tell, but I'm kind of a noob, so apologies if I'm overlooking something obvious.
Android's recovery where it doesn't matter whether it's Stock or Custom can't be used to unroot Android if it got rooted by TWRP and/or Magisk this because phone's boot.img got tampered by those: you'ld have to completely re-flash phone's Stock ROM to get rid off of all modifications you applied so far.
Okay then, thanks for explaining.
Just to be clear, what you're saying is that it isn't possible to unroot a device and then restore just its stock recovery (to replace TWRP). You cannot undo modifications made to boot.img and therefore must re-flash the stock firmware?
What I do with unwanted system apps on other android phones is to remove the .apk from /system by booting into recovery and using the shell/adb with u**x commands (actually move them somewhere they can't be seen by the O/S with mv command).
Also when faced with dm-verity, Magisk just modified the boot.img
and changes fstab to take out verify from system mount & patches init and removed /verity_key.
I was able to uninstall Magisk (only phone mod was unlocked boot loader allowing custom boot over usb).
