You need kitkat firmware.zip
Flash this in rebootRuu mode and bootloader is also relocked before flash firmware.zip. then flash kitkat ruu.zip

[Q] Unlocked, S-ON want to restore to stock ROM but can't use RUU

My Desire S was unlocked but still S-ON.
I want to change back to stock ROM and stock recovery.
I've try
- RUU_Saga_hTC_Asia_WWE_1.48.707.1_Radio_20.28I.30.085AU_3805.06.02.03_M_release_199476_signed
- RUU_Saga_HTC_Thailand_1.35.1113.2_Radio_20.28d.30.0805U_3805.04.02.01_M_release_183327_signed
but it doesn't work.
What method should I use to restore my phone without rooting (hboot 2.00.002).
Thank you.
P.S. Sorry for poor English.
You need to relock your bootloader before installing RUU.
Code:
fastboot oem lock

It's working but still got an error [140] bootloader version error (different from the first error before relocked).
I bought in Thailand so I think I should use this one
RUU_Saga_HTC_Thailand_1.35.1113.2_Radio_20.28d.30.0805U_3805.04.02.01_M_release_183327_signed
It has only one version of Thailand's RUU.
What should I do now?

[S-Off] Convert to HTC USA Unlocked 1.12.617.6

this guide is probably not user friendly. im a long time htc user, and am just showing how i successfully converted my ATT A9 to the USA Unlocked A9 version 1.12.617.6
this should work for any A9 with the MID: 2PQ912000
if you have another MID like 2PQ910000, it may work but i cannot test -see step 2b (thanks @alray)
i also cannot test to see if this ACTUALLY unlocks the phone, because i dont have a nanosim from another carrier
finally, i am not responsible if you mess your device up and make it unusable, this worked for me.
i used SuperCID, 11111111, but this also may work with the cid of the unlocked phone, BS_US001.
Note: if youre using a different cid and/or mid you will not be able to install OTA updates. (thanks @htconeXX and @JochenP)
Extra Note: if you used superCID already, you can change it and try OTA again without reflashing, given you have not modified /system (tested by me)
prerequisites:
1.12.617.6 RUU: Here
drivers, bootloader unlocked from htcdev, s-off using sunshine YES PAY FOR IT IT WORKS AND THEYRE GREAT PEOPLE theroot.ninja
fastboot and ability to use command line
steps:
step 1: boot into DOWNLOAD MODE
this is the BLACK SCREEN that you can get to from the bootloader
from cmd, run
Code:
adb reboot bootloader
(or use the hardkey method)
which which will take you to the WHITE BOOTLOADER SCREEN
from there, navigate to "reboot to download mode" using the volume buttons and select with the power button
or
by turning off the phone, and holding the power + volume down buttons until you see the htc logo
step 2 change cid
once youre in the BLACK DOWNLOAD MODE screen, from your computer run
Code:
fastboot oem writecid BS_US001
from the command line (or fastboot oem writecid 11111111 for SuperCID)
(step 2b if your mid is something other than 2PQ912000 you can change it with the command
Code:
fastboot oem writemid 2PQ912000
which should allow you to flash the RUU (thanks @alray) )
then run
Code:
fastboot reboot-bootloader
step 3 go back into download mode, verify it says the cid youve chosen , and run the RUU you downloaded from above. follow the onscreen instructions to update your phone to 1.12.617.6
step4: re root, install recovery.
supersu BETA now supports /system-less root
you can find the TWRP flashible package here: http://forum.xda-developers.com/showpost.php?p=64161125&postcount=3
SYSTEMLESS SUPERSU is no longer beta, its WIP, and the post can be found HERE
the most recent supersu as of 12/31/15 is v2.65
(any supersu should suffice, but you know what they say, latest is greatest)
First flash twrp
Code:
fastboot flash recovery <recovery.img>
then boot into recovery and FORMAT YOUR DATA PARTITION
IGNORE PASSWORD PROMPT
GOTO WIPE>FORMAT DATA> and TYPE YES
reboot recovery
then sideload <supersu>.zip you downloaded earlier
go to advanced> adb sideload in TWRP
then from your computer run
Code:
adb sideload <supersu>.zip
which will patch your bootloader, and root your device

If it helps, I have an s-off, unlocked bootloader supercid and was able to flash this on a at&t branded a9
Hi Ae3NerdGod
you don't have to use adb reboot bootloader and - adb reboot download boots direct to download mode

yep, like said above, this should work on any UHL variant.
Can you remove my at&t branding too? Lol that'd be awesome. Nice guide. I'll be doing this when my at&t one arrives

Well with supercid s-off and stock unlocked rom, the 6.0.1 update will not take, downloads but wont install. I think I need to teh CID for a US unlocked phone.
cid AND mid
Gesendet von meinem HTC One A9 mit Tapatalk
SU 2.65 Beta is out. I would recommend you use 2.64 system less from here on out anybody to start with. There are issues with 2.63 (non-systemless) and trying to then go system less. More steps to ensure a proper installation.
2.65 Beta you can install right on top of 2.64 Beta in TWRP recovery. I tested this, no issues.

Do NOT try to convert a Sprint/CDMA device! It will break completely break mobile data because the radio firmware is incompatible.

Followed the guide and successfully converted my AT&T to US unlocked using SuperCID thanks to @Ae3NerdGod ran 1.55.617.4 Dev Edition RUU from @Captain_Throwback and updated to 6.0.1, re-rooted and installed Xposed on the stock ROM. I can confirm that all are working fine:good:

[CONVERT] Any Country Any Varient to US unlocked/dev variant

PreRequisite :
Debug ON, Bootloader Unlocked, S-OFF, Battery 50%+, HTC sync manager and htc fastboot app installed in computer and Unlocked/Developer RUU.exe downloaded from official htc rom site..
1) open RUU collection thread
https://forum.xda-developers.com/one-a9/general/wip-ruu-htc-one-a9-t3240344
download Europe version nougat HIA_AERO_UHL 2.16.401.3 Firmware zip, rename it to firmware.zip and transfer it to installed folder of fastboot application on C drive of your computer... ( unlocked dev us variant OTA firmware zip link is broken so i used European nougat firmware)
2)cahnge CID to "HTC__034" or "11111111" , change MID to 2PQ910000, Then flash the European Nougat firmware 2.16.401.3 zip via fastboot
command - fastboot oem rebootRUU
- fastboot flash zip firmware.zip
if asked again to flash firmware zip then repeat - fastboot flash zip firmware.zip
after flashing firmware complete , return to bootloader mode by - fastboot reboot bootloader
then enter download mode, do not reboot your device into system.. your device is now European Naugat Firmware only..
3)Now change CID to BS_US001 and MID to 2PQ912000 and ReEnter into download mode..
Run RUU.exe that you downloaded from htc site..
follow instructions and after process done reboot/start phone, phone will take half hour to start so don't be panic and let it take time, you can wait maximum of 1 hour..
this procedure to convert any variant to unlocked developer version is working well however there is one bug for me and that is battery is draining superfast even when there is no app working in background, so i reverted back to CID 11111111 and MID 2PQ910000 and reflashed european firmware and then european ruu.zip.. im happy on Nougat on European Varient.. but if you still want to try Unlocked/dev version then proceed with caution.. i am not responsible if your phone got bricked

I see what you did here with the firmware update. Wouldn't it be simpler to just extract the firmware from the US Unlocked RUU instead of flashing the Europe version (and having to change CID/MID twice)? That would make your guide easier for beginners if they use the correct firmware.
You can extract the the firmware from the RUU using Captain&nkk71 decryption tool and post a link to the file in your guide.

The exe has no UI, just run a command window and CD to that folder, then you can use the name of the exe as a command.
