hey, someone could have warned that the OTA updates don't work anymore after rooting the phone -.-... first with somehow reverted recovery (don't know how it happened) it failed, and now with TWRP it doen't do anything and sits idle in recovery mode, with no alarm clock... -.-
also I'm used to have a all-in-one-thread with links to the latest firmwares etc, I can't find this here.
so, what's the latest firmware, are there differential patches I can install with TWRP or only the >1GB full images?
I'm on version 10B or so, something with 'b'. from june.
Only solution is to flash v10b "stock" and lose root (by that you'll be able to Ota update), or the newer version (using LG flash tool). Note that you'll lose all date on your phone.
Edit:
By flash I meant using LG flash tool. (for which version you'll like to install.)

*Of course* OTA updates won't work with root...what else could you have been thinking??
You actually have been warned if you had read the root thread...

In the past, not all rooting automatically meant that OTA updates were stopped. This was an optional step you could take. Early on, when a phone is first released, updates from the provider should be expected - this is something why I might hold off on rooting ASAP. As the life cycle of the phone starts to wear on, less updates (or no more updates) so less of a concern. There was/is an app I use to use call OTA Root Keeper that allowed one to not turn off the OTA updates - as some are valuable like the coming Stagefright patches we should expect - and get the OTA updates and then also keep root. Taking an OTA update could mean you loose root even with OTA Root Keeper if part of the update is closing an exploit. That was always a risk. But for me, having updated proper software often outweighed the risk with losing root and in fact, OTA Root Keeper always worked for me so I never lost root on my phones or tablets. But as we know, phone makers and providers hate root so they work to close every exploit and I suspect that would be why shutting off OTA updates is part of the current root tool/method you refer to. Most are cool with shutting off OTA updates.
For example, in this current root method it clearly says "Now that you're rooted, MAKE SURE YOU DISABLE OTA UPDATES, if you accidentally take an OTA, you might not be able to roll back or fix it." so it looks as if in this case OTA updates are NOT shut off and you have to manually take that step if you want to.

this is not true.. this is exploit specific
the bootload is unlocked, therefore we have full access anyway, it's totally impossible to deny root to a phone with open bootloader.
therefore it should be doable to unroot, revert recovery back to stock, to ota, and do it all again. but it's annoying.
I tried to flash the OTA update (it's in /cache/xxxota/something), after renaming it to .zip and .img, but it didn't work.
any other way to simply extract the files from the OTA?
I was have root and update software via lg bridge. Now i dont have root but i dont need it till we have twrp and custom rom/s.

By the question you can tell that i'm rather inexperienced at this, but a buddy of mine(who has a Droid on VZW) and i were debating whether or not doing an OTA update after you root would cause you to loose your ability to root forever.
I guess it's different on both devices, but he contends that he could unroot his droid, which is running a custom 2.2 ROM, install an OTA update, decide he doesn't like it, then just go back to a 2.1 RUU from VZW or Motorola, and then re-root.
Everything i have read here about the EVO indicates that if i am already rooted, and i accept an OTA update, then i will never be able to root again. Does never, really mean never? Or is it just mean that i won't be able to root using the current methods to root the phone?
What if i had never rooted and then accepted the OTA 2.2 from sprint that may be coming this week, would i then be able to root?
What exactly does the update do to remove the ability to get /root access to the phone? Something with the bootloader, HBOOT, or what?
Thanks for the information. Hopefully, this will settle this question for my friend and I.

OTA updates typically break any existing root methods, and disable any current root access.
Some OTA's also update the phone in a manner which prevents older official roms (that have working roots) from being reinstalled.
At that point, you have an updated rom with known roots removed, that can't be rolled back, so the only option is to wait until another root exploit is found and released. Which may or may not happen depending on the device and whoever is working on it.
Hope that helps.
You can take and accept as many updates as you want....you just have to modify that update by replacing the new hboot with the engineering one.....that way you can freely flash zip files
HTC is tricksy and they dont let you roll back after the OTA. Motorolla may not have this so your friend may in fact be able to roll back to 2.1 (however he may be misinformed as well).
To root basically they find a bug to exploit that allows us to gain access as a root user. when the OTA updates come out 99% of the time they will fix this bug. HTCat least blocks roll backs so now you are on a new version of the software that you can not go backwards and the bug to root is no longer there.
While there are normally other bugs that can be exploited to get root it is possible that there isnt one or that if there is no one can find it. if they cant find it then it could remove your ability to root permanently.

while true accepting an OTA will not give you the chance to do this for most.
ok, that explains things a little better. thanks.
I'm new to all of this as well. My EVO has already been updated OTA by a Sprint employee while I was purchasing the phone. From what I've read it looks like I'm SOL until someone cracks 2.2. One quick question though... How long did it take people to be able to root the first software on the EVO's?
Hello, this is my first android device, so I'm not too experienced with the whole rooting thing. My device is currently rooted with the original firmware that came on it. (Galaxy Tab S 10.5) not quite sure which version is on here or even where to find out. I tried to do an over the air update and it wouldn't let me because the device is rooted, but apparently there is a new firmware version out, so I definitely want to get on that.
How do I go about getting the latest firmware installed and getting my device rooted again?
Thanks!
How you rooted it the first time, just repeat the steps again.
Well to get an OTA as far as I know you will need to un-root and try the update, BUT if you rooted with Chainfire method probably is gona fail, because that method trips knox, and the update is going to fail.
If for whatever reason you can update, you might loose root and maybe the exploit that worked with your current build this time is not going to work.
To find out what build you have, go to settings>>>general>>about device and there it's
That's why once you root you have to block or deny the updates until the people here with more knowledge report that it's safe.

I haven't tried it for marks but auto update via Kies should work. Even if rooted. Does not affect root. And does not factory reset. i. e. you get same effect as OTA.

can anyone confirm this?
should I use auto update if I'm going to root and install custom rom later?
For me only, once I rooted I purposely used titanium backup to freeze "system updates".
I still get normal app updates, but don't want any system updates, that may break root, until my phone is unlocked.
Ok thanks, if I update can I still root after? After the update if I do a factory reset will the update be lost?
An update can remove root, and patch the methods that a particular root uses to take effect, depending on what it does. That is why I am avoiding updates until the phone is unlocked.
By the way, I can't post on dev forum so I'll take advantage of this topic here.
I already know that Purple Drake's root is working till the V10I update.
I rooted my G3 and disabled OTA's. If I enable them again, run the OTA update (V10I) I'll probably lose root, right?
But, if I apply PD root, will I get root again w/o losing all my data?
thanks!
What is the advantage of the update, should I even bother with it?

I used the KINGOROOT technique to root my SM-T800. I had to downgrade to firmware T800XXU1ANF8_T800XAR1ANF6_XAR (ANF8) to allow KINGOROOT to work.
The SM-T800 is now offering an OTA update. The only detail provided is "Size 39.96 MB" No clue what version it is.
Is there any way to determine what version of update would be loaded?
Would root be maintained?
I have purchased SuperSU Pro, and enabled "Survival Mode", which says it "attempts" to keep superuser access across OTA updates.
Can anyone confirm whether SuperSU Pro's "attempts" are actually successful on the SM-T800?
Once rooted you should disregard small updates.
You never know what this update will do. It could do anything from something simple to locking your bootloader. It won't be the first time people have ended up locked out of their device after an update.
If you really want to flash it, let it download then flash it with FLASHFIRE.

I wasn't thinking of the small updates - I was going jump ahead and flash the latest stock Lollipop (T800XXU1BOE2_T800XAR1BOC5_XAR) Android 5.0.2?
At this point I've got the tablet usable with KitKat - thanks for all your help!
I won't have time to mess with it for a few weeks probably, so I'll defer the Lollipop update till then.
I guess I have already let it download something, although it doesn't say what. However, it is nagging me to install the OTA update all the time. So how can I
1) Capture the downloaded update file?
2) Find out what version it is so I can decide if I want it?
3) Stop the nagging to install the update?
If you're going the whole hog then just flash Lollipop with Flashfire and you'll keep root.
Hi,
I rooted a new A3 (2017) sm-a320fl device for a friend using CF-Auto-Root from firmware.mobi.
However, it turns out that after tripping KNOX and blowing the eFuse automatic OTA updates are now broken.
Is there any way to return to OTA updates?
My friend would prefer to not have root and return to a newly flashed stock ROM rather than not receive automatic system updates. However, I'm not sure if this will be possible at all, now that KNOX is already tripped and eFuse blown?
And if there is no way to return to OTA updates, then what is the easiest way to install updates from now on?
I missed the whole KNOX/eFuse development and went ahead too quickly and thoughtlessly without thorough research and now I'm dreading that there may be no way back to a newbie-friendly device for my friend...
Hope some of you can help us out.
Greetings,
shevtak
Flash the latest firmware available for your country on Odin and your friend will gets updates again without root
Thanks for the quick response - I will try that.
But I'm still curious in case I run into this myself one day: Can you also tell me if there is a known place to get the update files from and install these manually on the CF-auto-root'ed system (i.e. using FlashFire)? So far, I was only able to find complete stock firmware images, but not update files...

I don't recommend using FlashFire for flashing updates or so. With an locked bootloader it's highly to hard brick your phone ?. And yeah the only way to get the OTA's back is to flash the official firmware via Odin. A good rooting method is Magisk, you should try it out!
