Hi guys,
I can't find a clear explanation of this. So I would like your help. For the time being, I'm primarily interested in rooting and not so much in a custom ROM. I'll just tell you what I do and we could take it from there. Assume an unlocked boot loader.
1. I flash the HTC recovery partition with CWM or TRWP
2. I root the phone.
3. I enjoy apps that require root.
When a HTC OTA update arrives:
1. I extract recovery.img from the OTA zip (and I use OTA-root keeper too to regain root after the OTA-update has been applied)
2. I flash HTC's recovery.img to the recovery partition (just stating the obvious)so that the phone again has the stock recovery
3. I update the phone
4. I reflash TRWP or CWM to the recovery partition
5. I use OTA-rootkeeper to regain root.
Now with Sony, I've read there is no separate recovery partition. So the bootloader does NOT load the recovery directly when asked to. Instead it loads the regular kernel which in turn loads the recovery. So it appears the kernel needs to be modified and the recovery image needs to be stored somewhere. I've picked up some terms like ELF and Ramdisk but I'm not getting the bigger picture here.
Could you please tell me what the implication are? With HTC, I can easly apply the OTA-updates using my above method and not loose any apps or data. With Sony, it appears I need to do much more?

Basically
Download flashtool from flashtool.net
Use it to flash a .534 FW (Download any one of them from the megacollection thread in the general section)
Google Bin4ry root many android to root the phone
Let the phone update OTA
Install Dual recovery from here then update it using the package in post #321 of that thread

Hi guys!
I've finally received 4.4.4 notification to update my German Moto x!!
I'd like to know one thing before I proceed.. If I update, will I have to root again the phone?
My phone has unlocked bootloader so there is no problem, but right now I'm on holiday and I don't have a pc to root it again..
Thanks a lot!
I have not upgrade to 4.4.4 yet.
I don't think you need to root again
Thanks!
I've read some other user just flashed the stock recovery, installed the ota and flashed back twrp recovery..
Others instead use fwz method
I think I'll wait until I'm home just to be sure I need my phone during the holidays!

Hi, i was wondering the same thing. Is there a method for someone to create an update for rooted phones?
Also can you link me to the threads for flashing back to stock and what this fwz is?
thank you
Here you can find some info about FXZ (sorry for my typo)
http://forum.xda-developers.com/moto-x/general/fxz-moto-x-4-4-4-212-55-26-t2827307
In the same thread you can find the stock recovery, a user posted it. Just search stock recovery in the thread and you'll find it!
I'm not the right person to help you in detail.
I'm not an expert user
In the meantime I froze motorola OTA app to hide the update notification..
Guys, before anyone gets in trouble....there is no FXZ for the german (or any asia/european) Moto X's yet.
The only one released is the Verizon one....so DON'T flash the verizon FXZ.
You need to flash stock recovery back, and if the phone STILL won't take the OTA, also use "mfastboot" to flash system.img from the 4.4.2 FXZ (which IS released for the european/asia models). Afterwards, the OTA should install without fail.
You WILL need to re-flash TWRP no matter which method you use. You will also need to re-root IF you flash the system.img from the 4.4.2 SBF in order to be able to accept the OTA (you only flash system.img from 4.4.2 if the OTA fails after you have flashed stock recovery - it normally means you have modified /system in some way, and restoring the full system.img fixes this issue).
Good Luck - Remember: Don't flash the Verizon 4.4.4 FXZ to your non-Verizon phone. Not a good idea...
If your phone doesn't vary from Stock but rooted, you can get away with flashing stock recovery back on there and taking the OTA. (OTA wont install via custom recovery like TWRP, CWM, etc). And if that is the case, you will retain root. You can optionally flash TWRP back on there.
If you have Xposed installed, it will need to be disabled or removed for the OTA install to work.
It is when you mess with stock files in /System or other folders on the phone.. i.e. remove, rename, etc. files from them, that you may also need to flash system.img and possibly other parts. This is due to verification checks in the OTA zip itself. If you have to flash those parts, you will have to re-root. Not an issue if you have an unlocked bootloader.
Thanks a lot for your help and clarification!!
I knew I wasn't the right person
Guys just to be sure of the right process..
-download the actual sbf of my phone
-extract recovery.img from the sbf
-remove xposed
-flash the recovery with flashify
-take the ota
-flash back twrp recovery
Am I right?!
Thanks a lot

IF you do not vary too much from Stock (i.e. didn't remove, rename or replace any "stock" files on your phone), then yes.
Oh, for Xposed, there is a disabler ZIP you can flash from custom recovery located in /storage/emulated/0/Android/data/de.robv.android.xposed.installer (or /SdCard/Android/data/de.robv.android.xposed.installer ) instead of removing it, as sometimes removing it doesn't undo all the changes.
My N6 is rooted, SuperSU and TWRP. On build LYZ28J and want to update to LYZ28K.
It seems I have 3 ways to do this:
1. Use settings in SuperSU to fully unroot, AND flash the LYZ28J recovery.img to replace TWRP. Then I can take the OTA. After that I can rerun the Chainfire Autoroot script and flash TWRP. So i'm updated with no data loss.
2. Flash the factory image. No need to unroot or remove TWRP, but all data is lost. And I still need to reroot and reflash TWRP. Correct ?
3. sideload the ota zip. Just run adb sideload <ota.zip> . No need to unroot . My problem here is that the only place I found with the ota zip is on Droid Life, not a google url. I like Droid Life, read it all the time, but still... Does anyone have a google url link to the OTA ?
Is there another method?
How are others upgrading? Is #3 as easy as I described ?
sean
1. no. to fully unroot, you need to flash a factory image. if you just remove root, itll still think tour rooted because system files have changed. so, wont work.
2. you can, but why? you gave extra time that you want to burn?
3. nope, cant flash an ots while rooted ir havd chsnged system files.
4. just flash the system.img of a factory image ehen it vomes out, and you will not lose data, but will upgrade.
I've used this thread (http://forum.xda-developers.com/nexus-6/general/using-image-to-update-nexus-6-data-loss-t3053158) to update within Lollipop through several versions. It is always best to wipe data when going from one version to the next (Lollipop to Marshmallow) but as long as you are staying within Lollipop this should work fine.
Check this out, http://forum.xda-developers.com/nexus-6/development/fxz-nexus-6-recovery-flashable-fastboot-t3066052
IMO, easiest way. DL zips to internal storage, wipe, and flash. READ the "Read Me" in the first post. When you update it will get rid of SU. Once you boot with update the first time, you can go back and root with TWRP.
Chose to use this. Did not flash the new recovery image. Updated fine, BUT locked and no root, no TWRP. I'll need to run oem unlock again, wiping all the data.
Sigh.
Wrote too soon. SuperSU and TWRP were gone (even though I did not flash recovery.img). Developer Options was gone. So I needed run CF-Autoroot and still need to flash TWRP. But all apps and data remained.
This is great news, especially if we're going to get monthly updates.
To start: 5.1.1 (LMY48M), rooted, with TWRP for recovery
For every 5.x update so far, this has been my procedure using fastboot:
Flash boot.img
Flash radio.img
Flash system.img
After successfully updated, I'd use WugFresh's Nexus toolkit to root and flash TWRP.
I'm a fan of not needing to flash userdata.img, as I don't think that should be necessary given that the OTA wouldn't wipe installed apps and such.
I've read other threads about using fastboot to upgrade and am concerned about the boot warnings, which seem to require a custom kernel to circumvent. My question is: will the above approach still work? Do I need to flash any other files? If I need to flash a custom kernel, where do I get it, how do I flash it (is it just a custom boot.img?), and at which point in the flash sequence should I apply it?
Secondly, has anyone tried gaining root through the Nexus toolkit once upgraded to 6.0?
I'm looking for recommendations so I don't spend hours trying to unbrick my device. Thanks!
You'll also want to flash the 6.0 bootloader and why are you using the toolkit to flash twrp when you can flash it in fastboot along with the rest of the files?
Ah OK, I'll flash the bootloader image as well. Anything else to be concerned with? The toolkit has a feature to root + flash twrp as a feature, so I just use that.
Do the bootloader first, then reboot the bootloader before you flash anything else. There are instructions floating around here some where or you can google nexus 6 flash factory images. You don't have to flash user data as this will format all you data/ apps.
Just download the latest SuperSu zip (2.50) and put it on your SDcard. If you flash as you suggested and then boot directly into recovery, you will still have TWRP. If you don't flash the stock recovery.img to replace TWRP, it will replace on first boot anyway, unless you root imeediately, but you are probably booting to use the toolkit, which replaces recovery only to have to use the toolkit to flash recovery anwyay.
So do your flashes, boot straight into recovery, flash the supersu zip on your sdcard. Done.
Newbie to the 'Dark Side of the Android World' and just curious.
well, after rooting your phone you only need to flash custom recovery once then you can access it as many times as you want
Your question is a little bit weird. Can you link me to a place of reference? Or at least explain what you are actually wanting to do?
Flashing TWRP is a one-time action, once flashed it remain on your Xperia SP. However, FlashTool doesn't offer flashing TWRP to other partitions via fastboot other than the "boot" partition. So far, the only way to correctly flash TWRP is via a recovery.
If you indeed flashed TWRP image via FlashTool, then you are actually putting TWRP into your boot partition, and this makes your device to only boot into TWRP infinitely until you flash a ROM (which will of course again override the boot partition).
The reason why I asked is because this method of accessing recovery is posted in my custom ROM guide, so I want to know if you get this kind of idea from my guide.
Thanks
Hi there, I am currently running B383 on my P9, and really want to root it. However when I do, will I still be able to get future updates to the software? Do I need to unroot and lock bootloader first?
Also when the bootloader is unlocked, a message is displayed at boot about your phone being unsecured and non-trustworthy, is it possible to remove this message? (I used to have a moto g with an unlocked bootloader, and I flashed some file to remove the warning).
Thanks
I don't think there is a way to remove that message every time the phone is turned on. Mine does that too as I've unlocked the bootloader.
Did you unlock the bootloader yet? Because when you need to unlock it, the phone will basically be factory reset when bootloader is switched from locked to unlock (vice-versa).
And for OTA updates the best way is to do it manually, downloading the MV-PV file via Huawei Firmware finder (Full PV file which contains two files update.zip and hweu..zip, update.zip (system firmware) is flashed first then hweu.zip (The system apps).
You will need a custom recovery. The one you will need to use is TWRP (This one specifically - twrp-3.1.1-0-eva.img) to flash OTA's via custom recovery (To repeat you flash update.zip first then hweu.zip) You can ignore the errors if it prints any while flashing the OTA files as I did the same and it worked fine no problem.
When you want to root your phone, make sure to flash 'SuperSU-v.2.82-EMUI5-SELEnforcing.zip' via TWRP recovery to root your phone.
For the other questions, you do not need to unroot the phone to install the OTA updates. The phone will just unroot itself when the OTA update is flashed onto phone. You simply just need to re-root it again by re flashing the SuperSU zip as mentioned above.
When you need to boot the custom TWRP recovery you need to turn the phone off and hold power + volume up until Huawei Logo / text is displayed you must release both keys immediately after 0.5-1 second which is a short time frame to get the phone to boot to custom recovery or else it will boot the Huawei eRecovery instead.
