[GUIDE] Get Stock Recovery/Install OTA Updates without losing data.

* I'm not responsible about anything that may happen to your device, please don't follow this guide if you don't know exactly what you're doing.
* This guide is for Windows users only. If you can get the official "recovery.img" or "recovery_signed.img" from somewhere else, then you can follow the guide (b) and start from step 5.
* If you're on Custom ROM, this will not work for you. Go flash an RUU instead.
* Please download the OTA update zip file before starting.
* If you deleted any system apps before, doing an OTA update will probably fail with Status 7. In this case, you'll have to restore the deleted apps as they were. If it still doesn't help, you'll have to flash an RUU and then do the OTA update.
* After flashing the OTA, you'll need to run Revolutionary to install custom hboot giving you permissions to flash recoveries and other things through fastboot. (IT IS A MUST IF YOU WANT TO USE "Android Recovery Manager" to flash ClockWorkMod after updating)

Getting stock Recovery manually​

Download your stock RUU from here or here.

If you don't have adb, please follow from step 1 to 3 in Step 4 in this thread.

1. Once you downloaded RUU open it and wait until you get to the "View Readme" page where there is the picture of an HTC device.
2. Go to your temp folder (Generally on Win 7 it's in "C:\Users\USERNAME\AppData\Local\Temp")
3. Look manually for folders that have lots of characters in that format: "{XXXXXX-XXXX-XXXX-XXXX-XXXXXXXX}".
4. One of them should have another folder in it and 2 files, this folder should be in that same format "{XXXXXX-XXXX-XXXX-XXXX-XXXXXXXX} too.
5. There should be in that folder something named "rom.zip" or "firmware.zip", open it up, and extract the "recovery_signed.img" or "recovery.img" to your ADB folder which is usually in C:\adb
6. Go to C:\adb and make sure that "recovery_signed.img" file is there. If not, repeat step 5.
7. Open command prompt (Press the start Logo on your keyboard + R, then write cmd and press enter) and type "cd C:\adb" {without quotes}
8. Ensure your phone is switched on (regular home screen) and connect it by USB in charging mode (Ensure USB Debugging is On by going on your phone to Settings -> Applications -> Development and Check USB Debugging).
9. Enter the command "adb devices". This is to confirm your phone is connected. (It should come back with list of devices attached and your serial number)
10. Enter this command "adb reboot bootloader" and wait until it reads on your phone fasboot USB.
11. Then enter this command "fastboot flash recovery recovery_signed.img" or "fastboot flash recovery recovery.img" depending on the name of the .img you extracted and wait.
12. Enter this command "fastboot reboot-bootloader"

You should have something similar to this.

No Recovery for Europe 1.45.401.3.

Can i flash Europe 1.45.401.2? I´ve tried this but it keeps on waiting for devices, and yes i got HTC drivers properly installed.

Cheers,
PC

edit: manage to flash stock recovery back using the "b" method , done the update and it worked.

Another question: future OTA updates will run automatically, or for every ota i must enter hboot and flash update.zip?
Thanks.

I had original stock rom backup with super user after using revolutionary tool with s-off no super cid. My hboot was 17.1111.1. After using tmobile 1.29.9351 recovery image it ran through process and said done, wait for phone to reboot in to recovery, however it just reboot into stock rom 1.45.9035.1. The OTA 14mb by t mobile was there to install. It install and said sucessfully update to 1.50.9035.1. I attempted to reboot into recovery but triangle with red popped up. With power button and volume button held it shows Locked, Pryamid PVT SHIP S-OFF RL, HBOOT 1.18.0000. I tried several times to run revolutionary tool which I used before coping and pasting generated key, however it continues to say invalid key. Question 1, with s-off show why is it locked and what can be done to get root again.
