Possible to unroot by updating? - Fire Q&A, Help & Troubleshooting

Hey guys I got a new 5th gen tablet and downgraded it to 5.1.2 then rooted it.
well I'm thinking about returning it and was wondering if I could just unroot it by updating it then restoring back to factory defaults.. would that work or would I be better off flashing stock firmware?
I'd just rather not flash cuz I'm not sure which rom to use and don't want to brick it before returning xD

You can return as-is; Amazon has a no-questions-asked policy during the return window. TOS does not prohibit rooting.

[Q] Rooted phone on stock AT&T Rom - save to do OTA update?

Hey all,
So I rooted my phone about a week ago and got rid of all the garbage htc/at&t bloat. The rom itself is factory but I'm running a different kernel. Would doing an OTA update to 1.29 brick the phone or cause any other issues?
Avoid it? Flash a 1.29 rom from in here?
Thanks

It will be ok if you just unlocked the phone. But once you apply the OTA then more then likely you will have to root your phone again.
If you removed HTC and ATT stock apps, you won't be able to use the OTA update as it checks for those items. You would also need to flash stock kernel back.
Hope you backed those items up or have a full nandroid of it before rooting.
If you restore those items so that you can use the OTA update, you also most likely lose root and have to root after.
I believe bootloader status remains untouched though.

[Q] SlapMyMoto 4.4 Rooting/Unrooting

So I'll be getting a Verizon Moto X soon and I plan to root via SlapMyMoto. My question is this: If my device ever needs to be serviced for warranty or resold at a later date, will I be able to unroot with ease back to 100% stock 4.4 without a trace of the rooting? The process is so convoluted that I worry it breaks certain things and I won't be able to switch back to pure stock. Has anyone tried this?
"100% stock without a trace of rooting"... No. You can easily flash back to the stock 4.2.2 image, But the system write protect that "WpNoMo" disables, does not revert back (meaning, the system wp will remain disabled). So, it will be nearly indistinguishable from stock, but a trained expert could easily detect it (a single command sent over adb will tell you wp is off).

I was wondering the same thing. I rooted my 32g VZW Moto with Slap 1.0, but just received my Dev Edition from the $100 off sale. My plan is to return the original back to stock and sell. Will the stock recovery return when flashing back to 4.2.2? I wanna make sure the buyer can upgrade OTA and whatever like stock.

This. For all practical purposes, will the phone pass a warranty test and be resellable to act like a normal phone with OTA updates and the like?

Yes it will. Like stock depends on whether or not you disabled write protection completely.

I believe the answer is yes because the 4.4 OTA tripped the counter.

From what I've read, the 4.4 OTA trips the flash counter within the bootloader as if you had flashed something yourself manually. What I gathered from that is there's no way to distinguish a previously rooted Moto X from a completely stock Moto X with the 4.4 OTA.
That's good to hear. So I'll be able to root 4.4, unroot, and get whatever the newest OTA is (probably 4.4.2) without any issue?

when ever you want to go back to stock you just need to download the stock firmware and flash it via RSD Lite or Fastboot and then take the OTA

[Q] Updating DIRECTLY from 4.2.2 to 4.4.3 (Unlocked+Rooted)

So here's the deal, I unlocked my T-Mobile Moto X bootloader through Motorola's website about a year ago or so. I also rooted and didn't bother updating afterwards to anything since I had everything working perfectly for me. Now I need to update my 4.2.2 Moto X to 4.4.3 (or really anything >=4.3 just so I can use my Moto 360 that'll be arriving soon).
My question is, with an unlocked bootloader, rooted, TWRP 2.6.3.1, Xposed-installed Moto X, can I go ahead and flash a stock 4.4.3 ROM (for example from here: http://forum.xda-developers.com/moto-x/development/rom-stock-flashable-t-mobile-t2773675) and just call it a day?
I've been reading past threads and stuff to get back into the loop, but I just can'f find anything to answer me the simple question of updating an unlocked+rooted 4.2.2->4.4+ while keeping root. Just the simple question of, if I get a stock 4.4 image and flash it on my phone, will everything be okay?
I no longer have the passion and interest to constantly be fiddling with kernels, ROMs, and little hacks with my phone like I used to with my OG Droid and, to a lesser extent, with my Galaxy Nexus (plus I feel like it's gotten significantly less easy since those OG days).
I know (i.e. 90% sure) that one way to do what I want (kinda) is RSDLite/manually go back to stock without root on 4.2.2 and then accept the OTA, but certainly it has to be easier than that right? What happened to the days where I can just find a new Gingerbread ROM for my Froyo Droid and just flash it right then and there? Now everything is "go back to stock and do these convoluted steps."
(I'm sorry I'm ranting, I'm just really tired at the moment haha)
Thank you all, hopefully, for the help!
If you don't care about retaining your data, grab the 4.4.3 fxz and unzip it. Follow the directions for returning back to stock here: http://forum.xda-developers.com/moto-x/general/ref-complete-moto-x-guides-information-t2603358 but replace the files to be flashed with the files from the 4.4.3 fxz. Not sure where you got the idea that you need to go back to stock. Word of caution, once on 4.4.3 there's no going back to an older version.
I have the same question as the OP, on unlocked rooted 4.2.2 ATT Moto X, can i flash a custom 4.4.4 and keep root?

You can take the ota but you need the stock recovery. Since you are unlocked you will not lose your unlocked-ness(lol) if you take an ota. But you do need to be completely stock: no su, no custom recovery, etc etc. But once you upgrade to 4.4.3 getting root back is as simple as flashing the appropriate version recovery again and then flashing supersu.

OK thanks, but cant I just Flash a Rooted Stock 4.4.4 over 4.2.2? Thats a more to the point question

Yeah that would work as long as your radio is compatible with the rom. The rom you shared earlier should be fine. Just don't downgrade to anything pre 4.4 as that can cause issues because of partition sizes (or so I've heard). But after that I wouldn't take any OTA's cause your bootloader would be incompatible with the OTA and possibly cause a brick. If I were you I'd revert to stock and take the long way to 4.4.3 just so I can get the OTA for when Android L comes out. In fact thats what I plan on doing if the Sunshine bootloader unlock is successful. But if you don't care about that then everything should be fine.

Stock Unrooted?

Hi all, I just got back from basic training at Fort Jackson, I had rooted my phone before leaving and now I want to go back to stock, looking around I haven't seen anything and the one I did see was taken down due to hard bricking. So is there any way to go back to full stock Unrooted.

I would recommend using the LG flash tool and flashing the 10n kdz.

Yes, you can upgrade from the 10h to 10n, but you should not downgrade from 10n to 10h as there is a rollback flag that will prevent loading the stagefright vulnerable 10h and brick your phone.

Are the OS firmware signed as happens with IOS?

I am going to buy another fire 7 and I would like rooting from 5.3.1.0 with this new device too

You will need to start from scratch as there is no way to restore a full nandroid backup to this device (bootloader ≥ 5.1.x).
I meant if there is way to downgrade 5.3.2 to 5.3.1 forever.

OTA updates can be permanently blocked on 5.3.1 if that is what you are asking. The other option is to spin up a pre-rooted 5.3.1 build with OTA blocked (as has been done with other Amazon devices) but would require developer support as a toolkit has not been released for this device. Believe that would also require an exploitable bootloader vulnerability (ie: signature forging) which we obviously don't have.
well, I hope doesnt have problems and can do the same thing (rooting) and after that flashing cyanogenmod to the new device. I received it the next week so I wish than Amazon doesnt update its firmware to 5.3.3 yet...

If it does come with with FireOS ≥ 5.3.2.1 consider a refurbished unit from Amazon Warehouse. I have purchased several representative models from various generations. Aside from packaging all were indistinguishable from new and arrived with older firmware.
thanks
