Backup downloaded ota update without root - Upgrading, Modifying and Unlocking

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.

Could not install the system update 1.54.15409

Every time I click update on my developer mode M8, it restarts automatically in the TWRP recovery mode. I have no choice but to reboot in recovery mode and the phone loads again asking me to update. Has anyone experience this? I am still on the stock ROM withe XPosed installer if that matters. Any suggestions will be appreciated, thank you!

Do you have a TWRP backup? You could restore it in TWRP if so.

I have a some of backups I created manually a couple of days ago but how would a restore of those backups update the system to 1.54.15409? Don't the phone still has to download the system update again?
You are asking for trouble trying to update on rooted, custom recovery and xposed framework installed..
Soff, Revert to stock, flash stock recovery, and then update
sent from my mobile device

Oh I see. In that case I'll just get one of the custom ROMs from here that will have the new system update. Thank you!
Phone has to be 100% stock, inc. the stock recovery and kernel, to flash an OTA file as it checks to make sure the phone is stock. ANY change to the original system and it'll fail

You have to have firmware that matches your hboot, and stock recovery. Doesn't matter if you are unlocked.

Lost root and cant boot into twrp after 4.4.4 OTA update

Hi, My htc m8 is bootloader unlocked from htcdev and was rooted at 4.4.3 with stock rom and S-on.Yesterday i got 4.4.4 ota update and after the update,I lost my root which was rooted by supersu.Then i tried to boot into twrp via fastboot by issuing this command:
fastboot boot openrecovery-twrp-2.8.1.0-m8.img
and pc screen says download ok and reboot but phone still stays at fastboot screen and just hangs there.Then i will have to keep pressing the power button to boot it normally. and this method of booting into twrp without actually flashing was working before.Any ideas please.Thanks.
Yeah it stopped working. Flash the custom recovery. When you get the new ota you download it but install it later and extract the recovery.img from the new ota and flash that before installing the new ota.

Thanks for the reply. Actually i have allready saved my ota file before upgrading.Can i do anything without flashing custom recovery?
Well depends on what you want to do. Give root access is only possible with a custom recovery......

Ok. So if i understand correctly, i will flash twrp and will reroot by flashing supersu again. right.
and what would be the benefit of extracting the recovery from ota and flashing as i have already updated to 4.4.4.I would like to get root again and want to remove the traces of twrp so that in future i can get OTA updates like now as i backedup everything by booting into twrp but without flashing it.sorry for the questions as i am kind a newbie. Thanks

You can always return to stock recovery. You're making it harder than it needs to be.

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.

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.

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:

Means if I'd like to unroot my phone by doing nothing, this is probably the easiest way?
