OTAs and CWM/TWRP

I'm reading the threads and seeing a consistent pattern (and experienced it myself). Referring at least to 4.1.2 -> 4.2 and 4.2 -> 4.2.1, it seems that you can do the OTA update if you if you have CWM but not TWRP. If you accept the OTA and have CWM, it will reboot into CWM, apply the update, ask if you want to preserve recovery and su, and reboot you into the new version.
If you have TWRP, though, it seems people get stuck at error 7 or similar.
When a larger version comes out in the future though I suspect we'll have to flash by hand as the OTA could blow away custom recovery; but for the two mentioned above at least, it wont kill CWM and installs fine with it in place.
I've loved TWRP in the past, but in this case it looks like CWM is handling the OTAs more gracefully. It's just a random chance that I have the latest CWM on my N7 instead of TWRP.

I have never used twrp, but I have done the last updates through cwm recovery and kept recovery and kept root. Definitely recommend cwm recovery.

I just got the OTA here, on TWRP 2.3.2.1, Nexus 7 no 3G. No errors, just worked.

Yeah just got the new update and I'm still rooted

And you are using which recovery?

Both work. If they don't something else is going on.

Just took the 4.2.1 update im still rooted using TWRP...

Status 7 is usually a security thing regarding the signature I think. If anything CWM has signature verification off by default.

I really don't understand why people are having such a hard time understanding what is wrong when they receive an error message with the OTA update.
It's not complicated people. You don't need to be a friggin' brain surgeon or a senior level developer. The error message TELLS YOU what the issue is.
Verifying current system...assert failed: apply_patch_check("/system/SOMEFILE")
Guess what? Something is wrong with SOMEFILE. You either modified it, deleted it, "froze" it in TiBu, or did something else that is causing the update to break.
If you look at the updater-script, you can see everything thing the OTA does. It's just a long batch script basically.
The ONLY way this 4.2.1 OTA update is going to fail due to recovery is if you are using the wrong recovery for your device (ie: grouper on talapia, etc.).

I hear what you are saying but....my N7 is stock, untouched, unlocked & rooted, yet I had problems with CWM & TWRP with the OTA and flashing the update manually.
I had to go back to stock recovery for both updates.
But I can see in this thread some have the OTA update working fine, one thing we all have in common is the N7, yet varied results.

Was your unit a 3G or Wi-Fi only model?

OTA?
I hate to be the hater, but why would anyone here take an OTA? The reason this site exists is specifically to help people to not use the stock software. If cwm survives OTAs it is probably an accident, lol.

What are you talking about?
XDA is in no way a site dedicated exclusively to "help people not use the stock software". It's a place where people can discuss their hardware/software including stock/custom/etc. usage and modifications. So not only is your comment 100% incorrect, but it's also contrary to this thread in particular. The thread title clear talks about using a CUSTOM recovery with an update to the stock software. So even if you were right (you aren't), your point is counter-intuitive.
There are many people here that are either mostly or completely stock. That's their personal preference and it's completely fine and acceptable. And it most certainly doesn't mean they don't deserve help or assistance here.

Also, while OTA updates are written in such a way to remove suid root on the su binary and reinstall the stock recovery image, most new custom recoveries have a work around in place to prevent this. Not to mention it's trivial to restore them back after the update.

No accident ... I updated my N7 from 4.1 to 4.2 still rooted.. And I just updated again to 4.2.1 ... Don't know about you but I love these kind of updates
Also I like my devices stock, rooted and a few tweaks here and there along with rooted applications... I'm sure there are many of me out there.
-Google

I prefer to never actually flash the recoveries.. just adb boot them as required - that means my system is always stock for the updates and I can pick a recovery at random should I want them (although generally I only use them to get a root shell to install su when I get a new phone).

I am rooted stock with cwm touch and the ota fails staus 7. I'm pretty sure I didn't do anything to "break" the update for myself. It's kind of funny the clockwork stops and asks about flashing an untrusted rom and then doesn't allow it. I would rather sit out of this whole 4.2 bs anyway.

I was rooted and stupidly just clicked the update to 4.2.1 without thinking, it didn't even occur to me to take any measures to keep root or custom recovery. So I lost both. It only took a few minutes with Wugs' toolkit to fix though.

I've taken three OTAs with TWRP and had no problems with any of them.

[Q] (AT&T) Best path to 4.4.2 from 4.4?

My setup: 4.4 ATT Moto X, Rooted (by way of latest jcase method), Locked bootloader, and I'm pretty sure write protection is off (though I don't remember how to check)
What I am wanting to know is how would and should I be able to get to 4.4.2, and get my root back (as I'm not confident any method will be able to "keep" my root safely without screwing something else up)? What's the best way based on my setup, and what files or tools would I need(stock 4.4 or 4.4.2 ROM, a new recovery image, etc)?
Since the root method I used hijacks the recovery, I suppose I technically don't have a functional one (other than it maintaining my root). Do I even need a custom recovery? I don't ever plan to flash anything other than basic stock firmware, though I may toy around with Xposed in the future. Also as a sidenote, im currently using ART instead of Dalvik. If any method or technique might conflict with that (other than Xposed), then let me know to the best of your knowledge.

Write protection will be enabled on 4.4.2. You can have root, but a shutdown or hard reboot will erase the changes you make that are root oriented.
As far as getting to 4.4.2.....tonnes of info already here...multiple threads.
Here's a basic guide...and Google can help too. Read any thread related to 4.4.2 and locked bootloaders.

I am using safestrap on my locked AT&T moto to get 4.4.2 + root + r/w on system - works perfectly.
(I modified the OTA to create a flashable zip that patches stock 4.4 up to 4.4.2, without updating the bootloader. I have an untested 4.4.2 flashable zip, and when the official SBF is released, I'll make another and test it myself.)

Honestly i dont even care to have an unlocked bootloader. I just realy need root after I update. Write protection, so far i think, i've only needed for AdAway to work on my phone, though Im sure I have used or applied it else on my device. And thanks for the thread, but I was already subscribed .

While I would like to test that out further for you, I have only one phone lol. I very lightly looked in safestrap sometime ago when I was trying to find how to root previous versions of my phones software. Back then I didn't feel I needed it, as I was and still am trying to keep things simple this time around with my Android device. I'll look into it again and see if needs have changed, but would reeeeeally like to just find a way to get root after updating. Your way does actually sound enticing however.

The only ways to use 4.4.2 Rooted with Write Protection DISABLED is the Safestrap way, or to unlock your bootloader.
Since you have AT&T, Moto doesn't give out the code to unlock your bootloader (Non-Developer Edition Verizon phones are the same way.) so if you really want to unlock your bootloader, see -> http://forum.xda-developers.com/moto-x/general/verizon-moto-maker-bootloader-unlock-t2680651 I know the thread title says VERIZON but it works for ATT users too.

I see, thanks for the explanation, because I certainly wouldn't have know it was for AT&T users too! I'll check them out.

So essentially, I cant just install Safestrap, then update to 4.4.2, correct? I'd need to do what you did, which is to modify the OTA?

Right. You want a modified version of the OTA that does not modify your bootloader and will patch /system from 4.4 to 4.4.2. I also manually patched the kernel up to 4.4.2.
And, my experience is that you also have to downgrade to 4.2.2. I don't quite understand why, but I have never been able to upgrade to 4.4.x (neither from the 4.4 leak or the official 4.4 version) without going back to 4.2.2 first. The eclipse ROM instructions, on the other hand, suggest that a safestrap:twrp factory wipe might be enough, but I remember trying that once, and it didn't work. YMMV
I already made a zip to flash a full copy of 4.4.2 (not a patch) that I made from my system dump, but it hasn't been tested. (I'm waiting for the SBF.)

Alright. Well I guess I'll have to wait a bit for someone to come out or prove there's a safer, surer method to update. Moto always did like to make thing like this difficult, heh.

ReRoot possible. On 4.4.4, installed update, lost root.

I meant reroot possible? It was a question. Accidentally out a period on the end.
Newbie mistakenly installed update and lost root.
I was already on 4.4.4 rooted. Received an update notification from AT&T. I pressed on update. Everything came back up but lost root. I'm I able to root without going back to 4.4.2?
Thanks in advance.

Someone correct me if I'm wrong but I believe the only way to root 4.4.4 is to go back to 4.4.2 and then follow the 4.4.4 root upgrade guide posted in I believe the general section it's actually pretty easy but does make it harder to use safestrap if you use that very often.

It's easy but unfortunately to resetup my phone is very time consuming.
I spent a lot of time removing apps, adding apps and configuring.

Thanks. That's the procedure I used to get my phone rooted to 4.4.4. Like I mention, I was already rooted with 4.4.4 and installed a OTA update which unrooted my phone. At the moment, it sounds like I have to lose all the work I've done on my phone and start over unless I'm missing something.

Root and updating su binary.

I rooted my ls995zva using king root (because that is the only one that would work). I have chainfire su installed. I use freedom flex to install twrp. On 4.4.2
Now that's out of the way. Here's my issue. When I open up SuperSU it says that the binary needs updated. I have tried both the normal and the twrp method but to no avail. I have rebooted into recovery and tried finding the file myself but can't. I have downloaded an update manually and flashed in recovery. It says successful but at reboot my supersu app is gone. On top of that, I get fickle root access with king root. Any help is greatly appreciated. Thank you for reading.

I used brute force/stump root method on my LS995, no problems, complete root access and updated twrp/su.
I don't have any experience with king root.

Name looked familiar....
I smashed the screen on my oneplus one, went back to the flex while waiting for the Two. I decided to stick with the flex for a while , but slightly disappointed about the lack of development on the flex especially when the one had so many options.
Did you leave the One?
Did you figure out your root access?

I still have the one as my backup. But my primary is the flex. The size and some of the lg apps are wonderful. Really wish the venom team would come and develop for lg. Lol. My root is spotty at best. Some apps I have to open 6 or 7 times before they're given root access. Now I'm faced with the daunting zvb update. Last time I downloaded it and flashed it my phone was useless for 3 days. I had to reflash factory stock from my computer and start all over.
Sent from my LG-LS995 using Tapatalk

I'm sticking with my flex because of durability at work.... Lol.
I'm on ZVA and brute force/stump root worked, which was over in the lg g2 section. I haven't updated with root because it seems to brick phones.
I have tried to get some devs over here but no takers, so if you know anyone interested.... I wouldn't even mind paying for someone's time, especially a cm port.

I want to root my AT&T Note 3 N900AUCUEOC2 Lollipop 5.0

Hello
i know there are many threads about rooting, i have been looking around the web for a few hours, you could say i am a noob when it comes to rooting. I have found many methods of rooting, some are lengthy and require the user to copy the files manually and some offer 1-click apps that do the root. In the end, i got confused and couldn't make up my mind. which is why i want to ask about my specific device, i have an AT&T Galaxy Note 3 N900AUCUEOC2 running Lollipop 5.0 (i updated from 4.4.2 ), the phone is not unlocked, it is still as it is since i bought it.
what is the best way for me to root? i have tried Towelroot, but it said my device is not supported, even though i have seen people on here with the same exact device claiming that it has worked for them. if you can give me instructions or provide me with a guide that can work with my phone i would appreciate it, i am really concerned about bricking it.

Thank you so much that was very helpful, one more question if you don't mind. Since I have to do a factory reset I have to back up my phone. I have also been looking around for apps or pc software that can preform a full back up, but for the apps they require you to be rooted, if not then they don't do a full back up. I was wondering if I'm missing something, I have never done a full back up, I was wondering if there is a away to do a back up that can save pretty much all your apps, data and app data, in such a way that when you restore the back up your phone comes back exactly to where it was. I haven't done that before so I'm not sure if a back up can actually do that, let's say I restore the back up, are all my apps gonna be there or do I have to install all of them again? That's my main concern, I'm not worried much about videos/pictures/contacts etc because I know those can easily be backed up. I would appreciate if you can give me feedback about this, especially about the apps and their data. If you can suggest back up apps (preferably ones that you let you back up on PC) that would be much appreciated.

I don't know of a way to do this. Sorry.

Ok i have figured out a way to do it, i have been reading through the links you have sent, honestly i am very confused, you said you have OC2 and have done that already? in the links you provided i got lost because i wasn't sure whether some steps where required or just additional, i saw some steps that included wiping the SD card. the steps that YOU wrote seemed simple enough, i will start the rooting process tomorrow. i just have one favor to ask, if i decided to root can i still contact you if i encountered a problem or had a question? i just wanna make sure i can find help if anything happens. I am quite paranoid about it lol

Cool thank you so much man !

Sorry to add to your thread, I previously rooted this phone back in 2015 but since then jumped to many other phones without root and got out of the game. I need a refresher. In your notes above when you go to that link, there are a bunch of new files, can you provide some clarity for me?
1-Most say on 5.0 NC2 you have to use all 4 ODIN files not the all in one, can you confirm?
