Hi,
is that you get the update notification?
For me (i did'nt have the notification), I did it: being in stock 4.2.1 ROM, s-off, recovery custom, and root, so I changed cid with the fastboot command: fastboot oem writecid HTC__032 (HTC__032 = East Europe, me I had a French HTC__203 cid). Then reflash version 4.1.2 of stock recovery, reboot the phone, check the update, and normally you could do it!
For finalize, back in the bootloader to restore your original cid and reflash a custom recovery if you want !
Good luck!

Well i got the update notification but i cant update to 4.2 because i dont know how to restore the stock recovery. if its any help im running 4.1.2 and im on cricket which is the PLCCL variant

Download the OTA.zip, you'll find it in download folder.
Copy it to your PC. Inside the OTA.zip you'll find a firmware.zip, unzip this on your PC.
Then open the firmware.zip and you will find a recovery.img inside. Unzip this recovery.img.
Now put the recovery.img into your fastboot folder (in your PC) and flash it with the cmd:
Code:
fastboot flash recovery recovery.img
If all went well, flash back cwm recovery, make a backup and upload it for us

Device_CW_Install: No CW files. Skip cw installation.
(going to skip writing out what all the update stuff said and ill just show you what it sayed at the end when it failed)
Removing unneeded files...
Patching /system or /data files...

---------- Post added at 06:35 PM ---------- Previous post was at 06:34 PM ----------
if you're cricket than do this
first thing you need to do is flash a working clockworkmod recovery
then download this rar file and extract it somewhere and place it in your CWM restore directory
https://db.tt/C59wTTqK
once it's restored
place this file on the root of your sdcard and reboot into your bootloader,
it will search and find it just follow the directions on your screen to apply it. then reboot into your OS and except all further updates

[Q] one xl bricked need help

I have a one xl cid rogers001 hboot 2.14, baseband 0.23a.3 2.09.29.... jb 4.1 with sense 4+
I tried unlock bootloader by htcdev => ok
install recovery => ok. and when i installed this rom: http://forum.xda-developers.com/showthread.php?t=1868236, it was stuck in bootloader. i fogot root my phone before.
so i relock my device, and tried to flash this stock rom using adb : OTA_EVITA_UL_JB_45_S_Rogers_WWE_3.17.631.2_0.23a.3 2.09.29_10.128.32.34a_release_299850qstr7rxdbfuofl 6j.zip (was found in this thread: http://forum.xda-developers.com/showthread.php?t=2119610)
On cmd via fastboot i type fastboot erase cache =>ok
fastboot oem rebootRUU => ok
fastboot flash zip "filename.zip" It says " (remote: 12 signature verify fail") in the end cmd
What should i do now?
Thanks for reading and help me pls!!!!

Ok, first mistake is that you thought you needed to be rooted to flash the Viper ROM, you don't. All you need is an unlocked bootloader and custom recovery, which you had. You were probably stuck in the bootloader because you forgot to flash the boot.img from the ROM zip with fastboot, you need to do this because you're s-on.
The next mistake you made was attempting to flash an OTA. I don't know what made you think that you could do that but it definitely wasn't found in this forum (or anywhere for that matter). An OTA is only a partial OS, it relies on the correct stock OS to already be installed on the device to build on top of to update the existing OS. It failed for obvious reasons.
Unlock your bootloader again, flash a custom recovery again, and flash the ROM again. Make sure you flash the boot.img this time and it should boot right up. I'd strongly recommend you read the Evita FAQ thread and the How-To Guide For Beginners thread in my signature. Diving into modifying your device without the proper level of knowledge is a really bad idea.

Did you perform a factory reset from the bootloader at some point? If so you've corrupted your sd card, you should never perform a factory reset from the bootloader. If this is the case you'll need to use TWRP to wipe your sd card, then you should be able to mount it to Windows and use Windows Explorer to format. Once this is done you can for a ROM across again.
Exactly which build of Viper did you try to flash? What's the exact filename? Did you check the md5 before flashing?

yes, i did it more than once, now it's fixed, but when i mount it to Windows using TWRP, nothing happen, so i can't format it. and the same things when i tried to sideload. But in fastboot mode, it usual.
and i flashed the newest rom in this thread: http://forum.xda-developers.com/showthread.php?t=1868236 ViperXL 4.2 and i didn't check the MD5
back to my previous question, can i fash a custom rom without root?

I asked for the exact filename of the ROM for a reason, I need that please. Also, exactly which recovery are you using?
Sent from my Evita

Yes, you can flash a custom Rom without root. He already answered that. I strongly recommend reading up on your device before flashing anything else. I'd suggest starting with getting your phone s-off.

I disagree. I think it's a better idea for him to get his head around the simple operations like flashing ROMs before attempting s-off.

If you flashed a full Oreo firmware instead of just the dsp, radio and bluetooth images you won't be able to downgrade. Firmware can only be downgraded if S-OFF, and that's not yet available on Oreo. If that's the case you are very well stranded on Oreo for the time being.
To be honest those things are quite basic knowledge you should have learned before you started tinkering with your device. Today most people just start flashing away, while I - when I started it myself back on the Desire days - read up on XDA and other forums for about three weeks to know what is to know. Still reading and learning new ways to accomplish what I want from instructions by developers, themer and many other users. Might never stop doing so until I'll stop tinkering.

If he has the wrong or to old fastboot on his PC, he won't be able to flash the RUU, due to file size restrictions in older fastboot versions. On the other hand, I'd personally prefer the SD card method instead of fastboot RUUing, as that always avoids such problems.

I download ruu firmware, put it on root of ext. Sdcard.
Reboot the phone to download mode. In the starting of download mode, it give you to choose, vol + to flash, vol - to cancel.
The ruu firmware must rename to "2PZCIMG. Zip",
If you have twrp, you must wipe data.

[How-to][ruu] Flash ruu.zip to factory

If you have some problem with your phone like me (Settings app fc always) you can download your RUU.zip and flash it.
If your bootloader unloced no problem no need to relock.
Go to download mode and type:
Code:
fastboot oem rebootRUU
Now your booted to the black HTC screen. Make sure your Rom.zip file is in your adb/fastboot folder
Code:
htc_fastboot flash zip Rom.zip
This takes a couple minutes and you will most likely get a error (pre-hboot update: please flush immediately) and maybe your phone reboot sometimes.
Make sure device is still in ruu mode(black HTC screen).
Let it run and it should finish this time
After completed :
Code:
fastboot reboot
It will reboot to a fully stock build.
Just remember, anytime you get a "flush immediately" error, just make sure your still in ruu mode and reflash the zip.
The most common error is typically :
FAILED (remote: 90 hboot pre-update! please flush image again immediately )
Enjoy your stock phone again.

If you want to decrypt RUU you can use : HTC RUU Decrypt tool . You will got a system.img, boot.img, recovery.img etc...

Thank you. I was wondering how to flashing the zips.

Thanks OP.
I want to extract the stock boot and recovery from RUU but it appears the format of RUU provided here is different from the others.
Is it still possible to extract them?
And could this RUU rename to 2Q4DIMG.zip and place to sdcard and flash from device with download mode?

If y want to decrypt the RUU y need this : HTC RUU Decrypt tool
You can decrypt the ruu file and y can find the system.img, boot.img, recovery.img.

Hi, I flashed the firmware from the microsd (fimware 1.10.400.23). As with htc 11 normal model, just rename the firmware file corresponding to the phone model in 2Q4DIMG.zip, put it in the sd card, start htc u11 plus in download mode and it's done. There is no need to have unlocked bootloader.

I tried to downgrade from 1.24.401.2 to 1.10.401.23 with the SD-card method (non root) because of wakelocks and the low percentage of Deep Sleep of screen time off (confirmed today by HTC Nordic today and that HTC are working on a new update. The support person didn't know any ETA).
Everything seems okay underway when flashing but after boot and finishing the setup procedure, Wifi, Google account etc. I'm still on 1.24.401.2. I used the 1.10.401.23 in the first post.
Have anyone else tried to downgrade with non root?

My HK model got an update today to 1.24.400.03 and devcheck is reporting 61% deep sleep.
I have had almost none since the update from 1.10 to 1.24.400.01. the .03 update seems to have solved this.

I tried to downgrade from 1.24.401.2 to 1.10.401.23 with the SD-card method (non root) because of wakelocks and the low percentage of Deep Sleep of screen time off (confirmed today by HTC Nordic today and that HTC are working on a new update. The support person didn't know any ETA).
Everything seems okay underway when flashing but after boot and finishing the setup procedure, Wifi, Google account etc. I'm still on 1.24.401.2. I used the 1.10.401.23 in the first post.
Have anyone else tried to downgrade with non root?

Downgrade has nothing to do with root. You have to be S-off.

Yes

I'll appreciate if you could share the HTC Arabic (HTC__J15) RUU .

Can I install 1.53.401.5 RUU (Oreo) on top of a device with 2.55.401.1 (Pie)?

I have updated my device to the Pie update (2.55.401.1) as soon as I got the notification on my device but now I wanted to make some experiments with custom ROMs and I'm not sure how can I restore to stock in case something goes wrong.
I mean, I have the "2Q55IMG_IMAGINE_DUGL_O80_SENSE10GP_HTC_Europe_1.53.401.5_Radio_sdm845-000201b-1807311356_release_532179_signed_2_4.zip" RUU file and I usually just rename that to "2Q55IMG.zip", place it on my SD Card, reboot to Download Mode and press Volume Up. This restores everything in the device to stock.
My question is, since I now have 2.55.401.1 installed, what will happen if I do the procedure above which is 1.53.401.5? Will it work? I mean, the firmware is probably different... Will the update fail? Will it brick my device? What will happen?

simple, ruu flash method erase all data,except microsd(so make a backup) and install previous firmware.
Check your CID before Flash ruu

Thank you but that doesn't really answer my question.

Today I flashed the RUU 1.53.401.5 with already existing 2.55.401.1 and it worked without problems.

I did the same but sometimes I need to flash the RUU twice for the phone to boot, not sure why.
