Could not verify update - Xperia Z3 Compact Q&A, Help & Troubleshooting

I have the D5803 running 5.0.2 (stock rooted) and it recently got an OTA but after the download it says "Could not verify update" is there a way to fix this?

OTA's does not work in many cases if you've modified your system partition, which you've done by rooting your phone. To upgrade to newer firmware version, either flash a stock firmware from a .zip file or use Flashtool.

[Q] C6903 Firmware for USA ...

I own a C6903 in USA.. the firmware version is 14.3.A.0.757 Customized UK
I am constantly and annoyingly receiving OTA update notification about the 14.4.A.0.108 update, but it cannot update because of 'could not verify' error. It also cannot update through the PC companion software, it says 'the phone/tablet contains modified software that cannot be updated'
Any idea on the cause of this error? Can anyone suggest a suitable firmware that can receive OTA update?
You have a rooted device or modified in some other way.
It's good that Sony prevented Ota updates for such devices as back in the days it caused a hard brick.
If you want to update then you can do this in a few ways :
Put your phone into flash mode and update via pc companion (your phone will be 100% wiped including internal storage)
Download an FTF from xda and flash it via flash tool (all will be wiped)
Get yourself a recovery from @[NUT] download a custom rom with the firmware of your choice and flash it. There are some that will not wipe your phone and you'll keep root that way.
Good luck
thanks a lot for clear and concise direction... got to update using the flashtool... everything good so far...

Getting the lollipop OTA (india)

I have a rooted xt1068 running on 4.4.4, Bootloader unlocked, System version 21.11.14.titan_retaildsenall.en.03, Build number KXB21.85-14.
I do not have a pre root recovery backup.
I can't flash stock firmware from stock recovery for some reason. I am using the firmware links posted on xda.
Somebody please tell me what to do to get the official OTA

Rooted + TWRP stock ROM update question

Hi I have a xt1803 G5S Plus, retgb and have recently unlocked bootloader and rooted my stock ROM which is NPSS26.116-26-14.
I have noticed there are higher version numbers available like NPS26.116-61. How do I go about having the latest stock ROM with twrp and root access? I'm guessing the stock ROMs are not flashable via twrp. Would I have to flash the latest stock ROM via ADB like it explained here
https://forum.xda-developers.com/mo...lash-official-firmware-moto-g5s-plus-t3681018
and then unlock bootloader again, flash twrp etc like starting from scratch?
I honestly would not recommend flashing NPS26.116-61 to your device. Despite the version number being higher, that firmware is actually for a different region (I think NPS26.116-61 series firmwares are for India and Indonesia, whereas the NPS26.116-26 series is for EU/UK). If you flash that, you may find yourself ineligible for OTA updates at all, since your build does not match that expected by the stock OTA servers, and if there are incompatibilities between the firmwares - since they are for different regions - you may have issues with IMEI/SIM access.
If you wanted to update though, you'd have to follow the steps in that guide. Though I don't have a G5S Plus, you would have to remove TWRP/root through a stock ROM flash (no need to re-lock bootloader), then update via OTA, then flash TWRP and re-root. If you can find a stock ROM with the same firmware build as you have now, you may be able to preserve your data by omitting the 'fastboot erase userdata' command from the stock ROM flash commands, but I would recommend you have a backup (e.g. TWRP backup) before flashing anything.
There's a copy of the NPSS26.116-26-18 stock ROM (June 2018 stock ROM) here, flash at your own risk: https://forum.xda-developers.com/showpost.php?p=77025728&postcount=507 This build was released as an OTA update to retgb devices as reported here: https://www.reddit.com/r/MotoG/comments/8w0c0c/june_patch_now_available_on_retgb/

Sprint Z3 Play 9.0 OTA update sent to phone 7/7/19

Hi, I have the Sprint variant Z3 Play currently rooted on 8.1 with the last update from January and I received the notification that the 9.0 update is available to download and install. I've been reading on how I can install this update but from what I understand, I have to update/re-install magisk using the patched boot IMG from the stock 9.0 IMG. The OTA is labeled PCW29.85-36 however all the stock firmwares I've been able to locate are labeled PPW29.xx. Can I extract the boot IMG from this firmware to patch or does it have to be the exact PCW firmware. And is there an alternative such as unrooting the device, reflashing the latest Current Sprint 8.1 Oreo firmware, taking it back to stock while keeping the bootloader unlocked, and then taking the OTA and re-root? My only reason for the root was to run Viper4Android and would like to keep this setup. I've also read on methods using LMSA but instructions on a rooted device are a little vague to me. Any assistance would be greatly appreciated.
