not possible to update with custom recovery.
if u want to update, u have to flash full firmware and corresponded recovery.img via adb. Then u can manually apply the ota update.

If you have TWRP, you can't take OTAs.
If you want to go back to stock recovery, just flash the stock recovery.img via fastboot for whichever build you want to go back to (you can pull it from a stock ROM zip that can be downloaded from ASUS).
If you flash an OTA while your ROM is rooted, you'll likely lose root, but it really depends on what they update. Some phones manage to retain root after an OTA, but it all depends on what's written during the update.
Basically the idea is:
If you use a rooted/custom ROM, you don't EVER take an OTA. If you're 100% stock, then grab the OTA and be the first one with the fresh update. If you're rooted/custom, wait for a dev to release their ROM update that's flashable through TWRP.

If you try to apply an OTA with a modified /system, it will fail. You can modify the OTA to remove the integrity check.

FAILED (remote: 12 signature verify fail)

I tried to flash new firmware using the instructions from http://forum.xda-developers.com/show....php?t=2696282 but it doesn't work. It says it's failed; I've done it numerous times to no success. How do I update my HTC__622 to version 3.xx.xx? I checked MD5 file and it says its correct. I used the file from this forum http://forum.xda-developers.com/showthread.php?t=2696514, but it still doesn't work. I'm trying to update my firmware so I can use the latest sense roms
Since you don't really understand how to update firmware manually ...
Why don't you do the easiest way ?
http://forum.xda-developers.com/showpost.php?p=56544097&postcount=2736
1. Install TWRP recovery
2. Restore 2.11.708.2 nandroid backup (you can select only system and boot if you want to keep your data)
3. Flash stock recovery
4. reboot and check for OTA, let the system install OTA to 3.32.708.4
5. reinstall TWRP or any custom recovery
6. install any Sense custom ROM that you like
7.done

Just another thing, do I need to lock bootloader and then unlock later on? Do I keep my root? Or do I have to root it again?
Sorry, I got so excited :fingers-crossed: finally gonna get some lovin' from the other sense custom roms! <3
Lastly, will my root be gone when I restore this? Will my phone brick if I update it to OTA after the flashing of the zip?
Sorry again if I got too many questions! I've been dying to find a way for this

No need to relock bootloader ... never do that.
You will lose root but you can easily re-root.
You don't flash the zip ... you need to extract the zip on your PC and transfer the contents to your device TWRP/BACKUPS/yourserialno/thisfolder
Restoring a nandroid backup will not brick your device.
Furthermore, your intention is to flash the latest Sense custom ROM after your firmware is updated to 3.32.708.4 and those custom ROMs come pre-rooted, so no need to manually root it.

Thanks a lot! Finally someone giving me answers I couldn't find :cyclops:
Oh, and if at some point in the future that I wanna try out the lollipop roms such as Skydragon, do I need to update firmware? Is the firmware in that rom different from the ones in sense roms? In other words, will I encounter problems if I flash a GPE Lollipop rom?
You can install GPE 5.0 SkyDragon on your 3.32.708.4 firmware but not on lower version like 2.11.708.2
The only problem you may have is WiFi disconnected when screen-off but to some including me, this is not happening ... only for some people on some firmware.

If you are S-On you will need to re-lock your bootloader for the OTAs, If you are S-Off there is no reason to re-lock.

That was what I've been told, and have also read on other sites. For example.
Personally, I never worry about OTAs. Being s-off and flashing firmware is a lot quicker than waiting on my carrier to update.
But thanks for clearing that up for me.

That's for manual updating via the ota zip. The thing i ment was official ota via update menu inside OS with stock recovery.

Do the same thing as before? TWRP should work now, so Magisk or supersu should be good to go.

Yes, but you'll have to flash the stock recovery and boot images from your current update (2.38.617.6) prior to taking next OTA or it simply won't update. If anything you or apps do using root to mount system as RW (or modify it), you'll have to flash stock system image prior to taking OTA as well. Best way is to restore stock system image and boot from TWRP backup then find stock recovery on forums or extract from current RUU and flash stock recovery then take OTA.

Backup downloaded ota update without root

Hi, i have an acer t07 device. When I try to update my phone through ota, which is 400mb, during the installation it fails. And then i have to download again the update. Is there a way to backup or save the downloaded files so it wont download again? Without root if possible. And also, custom recovery does not still work for my last-year-released device. Thanks

If your device rooted or custom recovery installed then can't flash OTA update because of modifications in system partition. OTA check system if found any modification then OTA update abort.

Flash stock over rooted to get OTA

I wonder is it possible to flash stock unrooted OOS over rooted OOS in order to install small OTAs. After updates plan to root again. Does anyone know whether this is possible or not? And, any side effects could occur?
I search over internet and couldn't find any useful info about this.
Thanks in advance.
Technically you'll be updating your device by flashing the newest stock anyway. No need for OTAs. You can then re-root.

Not what i meant. Let's say I'm on rooted OB18. But i want to update it to OB19. all i have is OB18 stock firmware. So, can i flash OB18 over rooted OB18 and then update it to OB19 (ota). Then re-root.
The reason I'm asking this is i have a very limited data internet connection. So i can save GBs if this is doable.

Plan to keep a copy of OB18 around? If so, then yea absolutely it should work. Root will either modify your system or your kernel depending on the method, which both get overwritten if you flash stock.
Issue you'll probably end up having in the future though is that if you always use OB18, when it comes time to install OB20, you'll be downgrading without a wipe, which I don't think is a great idea.

No you can't.
Because OTA will fail for "partition mismatching": the systemless root alters only but anyhow the /boot partition.
You must update with FOTA (Full OTAs), doesn't matter you're using stock or TWRP recovery.
The OxygenOS built-in updater should detects your system as modified and download only FOTAs.

Let's say he has open beta 18, rooted and twrp installed, if he flashes ob18 again over it, this will get rid both of the root and twrp, resulting in an untouched system, therefore, ota after this will be possible. He can then flash back twrp and root the device

But practically speaking, it's crazy to unroot system only for OTA.
It would be more reliable to download FOTAs on rooted system.
Then, if @GTRanushka is running Magisk (MagiskSU) as root method, it could be working even after firmware update.
Because of its systemless nature.

In order to flash OTAS has to have stock rom but also recovery stock and bootloader blocked but not installed the OTAS otherwise it tells you that you have something modified and you have to download the complete rom. (That does not suit you)

You don't need a locked bootloader for OTA just have to flash stock full ROM zip and stock recovery then you're good to go

Why i try to unroot and do OTAs is the much less download size compared to FOTAs.

Question on losing root after OTA

So op 5t released a new update, whenever i open the update screen it says root detected, i would lose my root privileges if I update the phone.
I wanted to know whether i would only lose my root, or entire thing of bootloader getting locked etc?
After updating will I be able to just boot into recovery and flash root file? Or whole process I would have to do again
Thanks
Updates reinstall the stock recovery. You have to flash twrp then root.

When you install an OTA it will NOT relock your bootloader, it will reinstall the stock recovery since that is included in the OTA zip and is forced installed to be sure the update installs correctly.
You will lose the root temporarily until you flash a custom recovery again and your root of choice.

Wait, really? https://github.com/topjohnwu/Magisk/blob/master/docs/tips.md#ota-installation-tips doesn't say anything about having to flash twrp again...
When an OTA is available, please go to Magisk Manager → Uninstall → Restore Images. Do not reboot immediately or you will have Magisk uninstalled. This will restore your boot (or dtbo if available) back to 100% untouched stock images in order to pass verifications. This step is required before doing any of the following steps written below!

Or does "100% stock images" mean the stock bootloader = flash twrp again?
Just to clearify, updating my phone by an OTA does not lock the bootloader but I'd have to flash twrp and magisk again..?

yee, but after you have used the OTA you will need to flash twrp again since the OTA flashes the stock recovery, or modify your boot image but that is a pain in the ass. :silly:
