[One (M7) Q&A, Help & Troubleshooting] karl_azytzeen:
What do we need to recieve offical 4.3 update?

I try to find out how, but i don't find enything clear, and furthemore am noob, because I have S-Off just for 1 week

Sumarizing: We need a phone with a free CID (those who are not from a carrier, which recieve updates trought it, and not so "fast")(dont puzzle this with IMEI issues).

For our phone, it should be free from factory, with a national, internaional or google CID. As example, Spain has HTC__304. Or if we had a phone from a carrier, we can change it.

Be aware taht if you want to change the CID the phone must be Unlocked bootloadr and S-Off.

By now its rocomended to first change CID to HTC__032 to recieve OTAs, and later cage to your preferred CID

CID List

HTC-UK HTC__001

HTC-FRA HTC__203

HTC-GER HTC__102

HTC-ITA HTC__405

HTC-Nor HTC__Y13

HTC-Norway HTC__H10

HTC-Poland HTC__B25

HTC-PTG HTC__506

HTC-SPA HTC__304

Here you have a tutorial to make S-Off in your phone, if you need it.

S-OFF HBOOT 1.54 Windows/Ubuntu | AIO RUNNER 1.1 [TAMPERED,SUPERCID,RECOVERY]​

If you are S-Off but dont have the necessary CID:

You will need a functional conection from PC to phe to use ADB. If you dont know about that take a look at the link of the top.

If not, a small tuto here:

DRIVERS

Win 7

Win 8

(HTC Sync must be fully uninstalled)

ADB & FASTBOOT

ADB & Fastboot

Extract the folder into the Drives root, to make commands shorter.

Open CMD and go to the fastboot folder, typing "cd c://fastboot" and press enter.

Now type adb and ress enter

CID CHANGE

- Conect the phone to PC in normal mode

*** Commands must be typed without quotes ***

*** You can use copy&paste with the quoted commands ***

-Type in the console "adb devices". To be sure if the connection is working and our device is detected. Your serial number will appear. If not, disconnect, reboot devices (PC and phone) and try again.

-Type "adb reboot-bootloader" to reset and enter in bootloader mode.

-Select FastBoot and click power. You will se "FASTBOOT USB" in red

- Nos desplazamos en el movil por el menu y seleccionamos FastBoot y Click en el botón Power para aceptar. Estaremos en modo FastBoot USB (lo indica en en rojo).

- Type in the console "fastboot oem writecid 11111111". If it works will show OKAY. (***)

(***) If you dont want Supercid you can change it for the cid you want:

- Type in the console "fastboot oem writecid (TheCIDYouWant)".

-To check that everything is fine reset the phe to bootloader mode againn and check if it shows the propperly CID(***)

Cool, we had our phone with the CID that we want, but OTA doesent arrives, WHY?!?!?

It is more complicated, we need also an Stock ROM, this means a hole stock phone (rom, firmware, recovery and unroot)

We can do this part by part, but the easiest way iwgo trought RUU. RUU is an executable file downloaded to PC taht, following a few steps will return our phone to a 100% stock and "like new" condition phone.

ATTENTION! doing this doesent affect S-Off or unlocked bootloader, but be aware taht recovery is replaced for the stock one and all files in the memory is deleted.

I recommend this RUU

RUU_M7_UL_JB_50_HTC_Europe_1.28.401.7_Radio_4A.13. 3231.27_10.31.1131.05_release_310878_signed.exe​

Dont forguet to check MD5 sums of all downloaded files!
