Back to Stock from 5.7.893

Theoretically this might work. Can you use the first backup that was made when you first rooted your phone to go back below 7.893

You can but there are several partitions that will not be restored (cdt.bin, recovery, boot (where kernel is located), as well as the radios). As long as this is true. You cannot be complete stock or flash any updates. As of now, if you are on 5.7.893, best to stay there and wait for a compatible update maybe in the future.

Well i was looking around on your cheesecake leak to complete stock forum and on page 5 a person named wingrider1964 used this
http://forum.xda-developers.com/showthread.php?t=1279825
the user chose 5 and and installed cheesecake and he got the ota update to 5.8.894. I am going to pm him and see what he says. At this point i dont mind if I lose root i have a Droid Eris that i can play around with. AGAIN LOSING ROOT IS NOT A BIG DEAL lol

I just posted on another thread about 5.7.893 or any other cheesecake leaked updates. (Not to be confused with "OTA" updates as they aren't). Anyone who has a non-OTA update installed right now, is screwed for the moment. There is no way back. This is the joys of a locked bootloader. The OTA updates out there are patching known versions to the new version. So, for example, the 5.5.886->5.5.893 update patches files from 5.5.886 including the boot image. The 5.5.893->5.9.901 update then patches the 5.5.893 files including the boot image. Those updates can *ONLY* be applied to the version they are meant to update. What we need is a full update installer that doesn't care what version you're on (ideal IMO) or an update made specifically for 5.7.893 (or whatever leak you're on). That's it. Our only options.

On the plus side nothing is wrong with my phone knock on wood i just would like to be on the path for ota

Updating after root

Forgive me if this has been asked before. I did search, but I couldn't seem to find an answer to this.
I have a dev edition model. I really want to root, but have been holding off because there are bugs with the current build of Lollipop and I'm kind of hoping Moto will release a 5.02 update soon to kill the memory leak and other issues. That being said, I have really been itching for root.
If I did root, what would I have to do to this phone to update it to the new version? Would I have to completely return to stock and wipe? Or could I ADB sideload? Seems like I was reading that you can't update at all when you're rooted, even if you disable root.
Without any idea how much longer it'll be before the next update, I'm finding it harder and harder to hold off on root, but I don't want to go through hell to get it back to stock and update it.
Thanks for any help and sorry if this has already been asked.

From what I understand, root is fine. It is installing a custom recovery that will stop you from getting the OTA. You can very easily undo root. As a matter if fact, you can pretty easily reinstall the stock recovery also.

Thanks for the reply.
Most of the time, that's true. I have updated a lot of phones by simply unrooting, applying the update, and rooting again, or using ADB sideload and then just rooting. But from what I have been reading about the Moto X 2014, you have to completely restore it back to stock before doing anything, even if you just use the temp boot method to root.
Is that wrong? I can't seem to find any info that confirms either way.

I've installed custom recovery, how can I reverse it and install the original recovery for update?

One advantage of root is you'll have Titanium Backup, so even if you do have to do a full wipe before applying the update, you could just update it and restore everything back quickly using TiBu. With lollipop, apparently the update file checks for the entire system checksum as a whole instead of each file so any slight modification to the system will mostly require pure stock and this is the same even with the nexus. So yeah, you most likely have to wipe your device before updating. I'd say, wait till Xposed for Lollipop is out, its almost there, once it comes out go ahead and root it, it'll at least be worth the hassle then

If you're rooted with lollipop and want to take an OTA update you can flash stock recovery and the stock system image. At that point you should still have all apps/data and be able to take a OTA update. The recovery and system files should be the exact version you already have and of course anytime you flash realize you could lose data!

Right. All you need to do is flash the stock /system partition and also the recovery if you replaced it. I don't know why everyone's talking about having to wipe the entire phone with the all the stock images.

How to install monthly Nexus security firmware updates without starting over?

Usually when a new Android OS version is released, I'll just start over from scratch by manually flashing the seven image files using fastboot. I then install the unencrypt kernel/boot image and also root.
Now that these security updates are coming out every month, is there an easier way in my specific situation to install the update only without having to start from scratch every time like above?

Flash the system image only (if radio is different, flash that too). That won't overwrite your user data/apps
Edit: When flashing the system.img, flash the cache.img as well (to be safe)

Thanks. That is pretty simple. I wish I asked this a long time ago so I could avoided a lot of resetting EVERYTHING up all the time. 2 more clarifications if you don't mind...
1) Would this also work for point releases, like say if a 5.1.2 comes out, or would it be better to reflash everything in that case?
2) No other steps like clear cache or anything? Just flash those 2, reboot, and then I should be good to go?

It should work just fine for point releases. For major releases (like when Android M is released), I will probably flash everything, and wipe everything (including userdata), and start from scratch ! lol!
In theory, it should work find even for major releases, but I'd rather start with a clean slate - especially with the new permissions manager that is being added in this release. I'd rather not take any old incompatible apps thru' - but that's just me
Clearing cache is usually not needed. I've heard of instances where some users get stuck on the Google boot logo for some reason when booting for the first time. If that happens, clearing cache seems to help.
To be safe, it may be a good idea to flash the cache.img too. It takes a few seconds. Better safe than sorry. I'll update my earlier post.

Is this the system update that just got pushed to my phone? It looks like a small update, like 26MB?
Mine tried to install and failed. My phone is stock, latest official version, never rooted, but the bootloader is unlocked and it is running the no force encrypt kernel, which I believe is probably what is causing the issue?
Only way is to restore completely to stock, take the OTA and then install the no decrypt?

I got the OTA today to upgrade to M from L- (on verizon) where can I Find that system image to flash- I tried sideloading the OTA and it didn't take.

I believe it's actually both of these things causing the OTA not to take. If anything, anything is changed from stock...no OTA. Bootloader unlocked, kernel, root, even just changing the build.prop (but you need root for that) would cause it to fail. I believe it checks every file and if anything in /system has changed, no OTA.
I've never messed around with the encryption pieces, but I'm wondering if you only flash the system.img (you'd need to re-root) if that would suffice or not as far as the update. You'd be flashing the entire system file instead of only the delta the OTA provides, but it's probably worth looking into.

Hmmm... Well, it takes 15 minutes to just wipe the phone and flash the new ROM with the toolkit, install my apps, copy my files over and set the phone up, so it isn't a big deal, I just want to make sure that I have the right version before I do that...
(LMY48M) That's the one that I want for the VZW N6, right?

I just use helium to backup my apps and everything. Even if I need to wipe it is a pretty easy restore process. I highly recommend helium backup.

Unlocked bootloader doesn't affect it, the customised kernel does though . But yes, you could just flash the system.img

Noob needs help with XT1096 on Verizon network w/ TWRP and keeps getting OTA prompt

Since there are not too many stable ROMs available on the XT1096 that support CDMA (I am using Verizon's network). I decided I would unlock my bootloader, flash TWRP and root the stock firmware. Well, the past few days I guess I did not update my phone all the way before doing this since I just got it not even a week ago and keep getting prompts to install an OTA. This will obviously not work with TWRP and when I flashed TWRP I selected to modify the system so the stock firmware would not rewrite recovery on boot. This has become a complete pain in the ass for me. Accidently I selected to install the OTA since it is always in my notifications and when it happened it would obviously fail in TWRP but then it would boot back into the ROM and then power cycle back into TWRP. The only way to stop it was to do a factory reset which is not what I would like to do every time I accidently select to install this OTA. So my questions to you awesome people who know more about this device are. 1. is there a way I can enable the to option to where I will always have a stock recovery and then I can just fastboot boot into TWRP if needed? Or is there another way where I can just possibly stop this OTA all together even though the prompt already says it's downloaded and waiting for me to hit install. Like can I just go into rootexplorrer and delete or modify a few system files that'll stop the phone for looking for OTAs? I don't reallyl care about the OTA since it's obviously not 6.0 since VZW got boned on that one. Looks like it's just some security patches.
I'm sure this is probably a really stupid and simple question, so I apologize in advance. But thank you SO MUCH to anyone who decides to help me out. I will appreciate it GREATLY!!!

Try using your favorite applications manager for root and freeze MotorolaOTA. This will prevent the update from being downloaded and you won't get messages about installing the OTA update.

No, it fails to install. You need to reflash the stock boot image to take an OTA.

I'm Sorry i'm so nooby in this regard.
So do you mean i have to basically get the stock ROM back again.
Then I can re-root like i did with the earlier version?

Yes. Razer's update engine doesn't seem to have the option to download full images like some other OEMs, so only fully stock ROM can be upgraded.
On that note, Razer seems to have set a week as the delay for releasing factory images, so if you want to keep root you might want to wait after an OTA, though we may be able to reproduce a slot earlier if someone captures the OTA package (but it's not as verifiable of course)

Not quite... The update will likely fail to apply due to checksum failures. If it did go through it would probably brick the kernel so that's a good thing. Sorry, there's not really a way to automatically root after official OTAs as they update block by block between two known states, and neither is rooted. It's just sort of not possible, by design. You have to unroot, update and root again.
The OTA package translucentfocus has provided allows us to reproduce a single slot before the week's wait for the factory image so we can root sooner.

Sorry, I didn't specify. It's the MR2 update for the Razer Phone 2. Original reply has been also updated with version information in bold.
How to update? Actually, I posted the OTA because it's really for someone to make a slot with root before Razer releases the Factory MR2 Images--as @CurtisMJ mentioned previously.

Sorry to bring back an old thread but just a few questions if you don't mind.
I just bought a used Razer 2 seems like the user rooted it (I was unaware) and it has been years since I rooted anything. I downloaded root checker and it said I was rooted. I assume I'm running the stock rom, though magisk manager was installed on the phone when I turned it on so I guess it's not stock. I guess this means I can not take any OTA or it could brick? I went into system update and it still checked to make sure I was up to date so maybe OTA isn't disabled? So much has changed with apps and rooting since I messed with it that I don't know enough and I don't want to brick or bootloop the device.
Thanks

Yes, that sounds about right. When rooted the OTA function doesn't disable right away. Only after its downloaded an update and actually tries to apply it it'll refuse. The new Android update engine is pretty good at not bricking. My guess is probably stock. If it's rooted, then the bootloader is unlocked, and it's not too bad. For magisk root at least all you need to do is flash the stock boot image and the OTA will apply. With factory images around and an unlocked bootloader you'll have a hard time bricking it. Just don't untick "OEM Unlocking" in developer options. Ever. (Or at least until you've fully restored stock firmware. It's supposed to be disabled so you can't make that mistake but Magisk hide tricks the firmware into believing the bootloader is locked so it's enabled. Whaddayagonnado)

Thanks for the detailed response I managed to get up with the previous owner on swappa last night. He told me he unlocked the phone but never actually got around to rooting it. He also said it is running stock and the reason magisk is still on the phone after a wipe is because magisk persists after a wipe.
Messages from him.
Sorry about that, I did unlock the bootloader but I never actually got around to rooting. I usually relock the bootloader before I sell it but I completely forgot. You can apply an ota because I never installed a custom recovery, something else I didn't get around to doing. You can easily relock the bootloader using adb. If you need help with this let me know and I can walk you through it. But the bootloader being unlocked has zero effect on ota's. You are all good to go as far as that goes.
Oh no you're absolutely fine with an ota. I just looked it up and you're absolutely right, magisk does survive a reboot now. Since I didn't load a custom recovery though an ota will install just fine. Although when an ota does install though it will most likely remove magisk because it will write over the boot.img with the factory one. Here is the link to the factory images. It includes instructions on how to install it. But honestly a new ota should be released any time now since the last one I think was November. Once that installs you will be completely back to stock.
Does this sound accurate to y'all. Thanks again

@Univsoldur His knowledge seems a little dated. Kind of how mine was a few months ago Anyways here goes:
If a root checker says it's rooted then it probably is. I'm not sure why he says it isn't.
Magisk does indeed persist through a data wipe. I wasn't aware magiskinit could unpack the manager APK though. Neat
He's right in that an unlocked bootloader won't affect OTAs, but having magisk installed will.
The RP2 uses the new A/B update scheme. In this case it doesn't matter whether a custom recovery was ever installed. Recovery mode is not used during the process of installation. Unfortunately the new update scheme is also heavily based on deltas, even on the kernel image, so OTAs will be broken as it won't be able to retrieve a full kernel image from the OTA servers. Some OEMs' ROMs can do that, but Razer's can't. You can flash the factory images if you truly want a clean start, but to fix OTAs and remove magisk, reflashing just the kernel image with one from the factory image should be sufficient. The magisk uninstaller won't work due to the data wipe so that's probably the only option.

Will that remove magisk and return it back to stock I would assume there is no threat of flashing the stock image. Besides that do I need to mess with the kernel?

I'm wondering if it would be possible to flash the unlocked Razer phone 2 firmware to the AT&T version. Would the bootloader need to be unlocked?

Yes, that will return it to stock and remove Magisk. No, if you flash the factory image you don't need to do anything further with the kernel.
