Hi all.

Is it possible to check if return to Full Stock actually worked, and if the phone is ready for OTAs ? A command or an app?

The bootloader is unlocked and the phone is S-ON.

EDIT: Is the following line in stock recovery sufficient?

Ok, Since i was not able to find the ruu before i restored a nandroid backup of a 1.27.400.8 dugl found in the google spreadsheet. So now i got a firmware update to 1.27.400.21 after rebooting and when i press install, it reboots to the stock recovery and proceeds till 24% and after that it shows the red triangle with an exclamatory symbol. Any way to fix this? since i want the oreo update. And if flashing ruu is the only possibility then is it possible to do it from a computer because i don't have a sd card right now.

Mine stayed modified even after closing the bootloader and flashing the latest RUU.

There is no app to check if you will get ota updates but I flashed the previous ruu before and got ota even with open bootloader

Thanks phreakymind.

I flashed the Nandroid backup

twice

via TWRP, as explained over here:

2. How-To restore an untouched/pristine system by using a Nandroid Backup

Now I don't have TWRP anymore. But it is sure that the system was modified before, since I deleted some (too many) system apps, and Phone kept on crashing every minute or so. Since Oreo should come in a week or two, I will see if will get OTA or not.
[HTC U11  Guides, News, & Discussion] phreakymind:
Well didn't try that one. I only flashed the latest RUU from an USB drive via OTG. Someone here told me that it's perfectly normal that it stayed on modified. But if you were successful with the Nandroid backup I might try that. Thanks

So you are not sure if your software Status was modified before?

Because Smartphoneguru stated that it always switches to modified and that it is not possible to restore to official without permanent s-off.

[HTC U11  Guides, News, & Discussion] 5m4r7ph0n36uru:
Well first of you are trying to flash a firmware.zip instead of a RUU. Second you seem to be in bootloader mode. All an everything has to be flashed in download mode since the HTC 10, but a RUU! For a RUU you'd ALWAYS have to do it as [MENTION=506238]OMJ[/MENTION] wrote in RUU mode. Did you even read the steps he told you? And if so, did you follow them to the point!?
[HTC U11  Guides, News, & Discussion] nivy19:
File i m flashing is RUU downloaded from page https://docs.google.com/spreadsheets/d/15JL3tRWDSVOUKo_revEYtQ_tRcOSJ0vWcvk8a7TK8Hk/edit#gid=0 and i only renamed it to firmware.zip.

Its located in folder with adb when i press shift and right click to open adb, ithink its good location. I m in fastboot mode and typing fastboot oem rebootRUU from download mode and i follow steps as he typed... Please help...
[HTC U11  Guides, News, & Discussion] 5m4r7ph0n36uru:
Which software number are you on according to a fastboot getvar all command in download mode!? And which of the RUUs are you trying to flash. Those two information are important IMHO. They have match at least!!

Otherwise you can always follow the guide in the third post of the OP...
[HTC U11  Guides, News, & Discussion] nivy19:
Yes i know they have to match, my htc model is 1.27.401.11 and i downloaded same version RUU... Its stills 99 error ;(

I have to use method without SD card, is there anyy other way to do it.... its freaking annoying that i can t back to stock ;(
[HTC U11  Guides, News, & Discussion] 5m4r7ph0n36uru:
Did you check if the md5 of the downloaded RUU matches the one on AFH. And is your fastboot up to date? I always check on those things before I start flashing. md5 got to match, bad well as the used fastboot or htc_fastboot got to be the latest available.
[HTC U11  Guides, News, & Discussion] nivy19:
How to check if md5 matches the one on AFH and also what is AFH? Fastboot seems to be up to date i was doing everything on with this one driver..
[HTC U11  Guides, News, & Discussion] 5m4r7ph0n36uru:
OK last answer for today. AFH is Android File Host, which is where those files have been uploaded and the spreadsheet redirects to AFH. There you will find the md5 that has been calculated during upload as well. After a download you can compare it using an App/Programm. Just google for "md5 checker windows" or the like and you'll find tons of it. Download the one you like most and feel safest with.

Next time learn everything about such things before you start tinkeringneith your device. It's a lot of reading, but you don't seem to have done all of it yet.
[HTC U11  Guides, News, & Discussion] nivy19:
Okay, i ve got it and program says md5 are matched. So what can be the real problem if everything should be fine? ;s

---------- Post added at 18:49 ---------- Previous post was at 18:20 ----------

Nothing difficult.. If you use a custom rom, you need to return to stock rom because this procedure of relocking bootloader needs to factory reset but to stock of them.. So:

- if you are not on stock, flash current RUU

- lock the bootloader: https://xdaforums.com/showpost.php?p=73298536&postcount=473

After that if you would like to receive next OTA and everything working properly, flash RUU again after relocking bootloader.

Yeah indeed [MENTION=7521917]ziand_[/MENTION] is. Guess what he did: took the burden from you, as you would have had to use the search function within this thread otherwise. A little self studies and searches are never such a bad idea if you really want to learn something about what you are doing here.
[HTC U11  Guides, News, & Discussion] 5m4r7ph0n36uru:
No. There's neither a permanent S-OFF, not a possibility to S-OFF Oreo. SunShine developers are still working on it, as only some versions are released already. And you'd need S-OFF to downgrade.
[HTC U11  Guides, News, & Discussion] namartlu:
Hi, I am currently on a Nougat custom rom and I am ready to upgrade to OREO (or so I think...) I like to flash stock OREO first and see if it's good. Can I just flash stock OREO RUU? That includes firmware updates (radio, modem, etc), right? I suppose I lose my data doing that?
[HTC U11  Guides, News, & Discussion] 5m4r7ph0n36uru:
Yes all as you said. But take into account that no downgrading at the moment. S-OFF for Oreo is not available as of yet, thus you'll be stranded on Oreo.
[HTC U11  Guides, News, & Discussion] Golv:
You can DOWNGRADE from Oreo to Nougat

without S-OFF

[MENTION=7521917]ziand_[/MENTION] did it successfully!

You can see his post with Google translator.

If you want downgrade please copy all commands from his post but from ORIGINAL message (G translator adds extra spaces to the code).

I hope that he will post this manual here in HTC U11 Guides, News, & Discussion.

Yes, there is a big risk! But this is

only for EXPERIENCE users

[HTC U11  Guides, News, & Discussion] 5m4r7ph0n36uru:
Yes I know, and I know how to do it and the risks involved. And that's exactly the reason why I don't recommend or mention it to anyone here. One muss t be extremely careful and experienced to perform this steps. Otherwise it'll result in a very expensive hard bricked U11 that only serves as a paperweight. As I experience many users around as inexperienced and thus wishing to be spoon fed with all and everything, cause they don't make themselves familiar to even understand the basics of tinkering.

And if you'd have read the post of ziand_ in Google translator fully you'd have seen that he links to his english description with exactly the same content here in this very thread.
[HTC U11  Guides, News, & Discussion] Golv:
Yes I know, but there was downgrade from Nougat to Nougat in that case...

Yes, there is a big risk! But this is

[HTC U11  Guides, News, & Discussion] 5m4r7ph0n36uru:
See that's exactly my point: as soon as it gets available here inexperienced users will use it anyways.
[HTC U11  Guides, News, & Discussion] Golv:
I changed link in my post for this reason..
[HTC U11  Guides, News, & Discussion] ziand:
On Oreo it became more safe because you can see that after the changing the software number is still on its place in download mode (it reads from another)... you can even continue to use the phone with this. We just allow to flash another one.
[HTC U11  Guides, News, & Discussion] 5m4r7ph0n36uru:
Well depends. It works for as long as decryption keys between different OS versions don't change. If it does though you'll still have an expensive paperweight.

Hello everybody!

I have a small problem:

my os is 1.27.401.12 and i want to change it to US unlocked .617 to install the oreo update.

I have sunshine S-off, SuperCID and manually changed the MID to 2pzc50000 ("fastboot oem writemid" or something similar to changing CID). als this is shown correct with "fastboot getvar all".

so, when I want to flash via the SD method, I always get the Error_10_RU_ModelID_fail.

made it. only thing i changed was the MID in capital letters.

I got the Error " 9 RU_SECURITY_FAIL zip from usb command in download mode"

Now i dont know what ist wrong where is my failure.

The only reason i have installed TWRP is to make good Backups

Now i have this big Problems with my first Android-Smartphone

I am not an Android specialist and i dont understand everything.

I need detailed instructions what to do.

You do not need to relock the bootloader to take an update.

Had this once on my end. Seems that in some cases there occurs a hickup anywhere. Only solution that worked was to run a RUU and start from scratch. Well nearly from scratch. I backed up userdata and restored it afterwards by booting to TWRP without flashing it, mounting system to and restoring data. After that e.g. my Oreo update worked like a charm.

As long as the RUU hasn't been leaked there's no proper solution, save one. There is a way to downgrade that has been given by one of the contributers over at my collection thread. But it is risky which is why I'd recommend to wait for the proper RUU.
