You may change the MID (at your own risk) in the android-info.txt attached and replace the one inside the firmware.zip if you have another MID.

If you have Super CID "11111111", you don't need to worry about the CID lists inside the android-info.txt file

​

DON'T FORGET TO CLICK THANKS IF YOU FIND THIS THREAD USEFUL. :p

Dear All,

I have noted a lot downloads of the firmware and most of them just don't even bother clicking thanks :silly:

I appreciate your encouragements and appreciation for my work so that it will give motivation to keep all you updated.

Thanks a lot for everyone contributed..

:p

To Check ModelIDs:

adb reboot bootloader

----- Mobile reboots---

fastboot getvar all

----Check the following line in the command window: INFOmodelid: PN0714000----

Steps for flashing:

-----

Windows users, need to do these steps first:

- move the file you downloaded and renamed (firmware.zip) to the C:\adb\ folder.

- next, in the C:\adb\ folder hold down SHIFT key and RIGHT-CLICK and select "Open command window here".

-----

Next, plug in phone to PC and type this in terminal/command prompt:

adb reboot bootloader

----- Mobile reboots---

Now type:

fastboot reboot-bootloader

After that, type:

fastboot oem rebootRUU

Note: You should see a silver HTC logo come up on your phone after executing this command.
Note: if this command freezes, just disconnect the USB cable and hold the power and volume down buttons until the device reboots. Then, repeat the steps above again.

Finally:

fastboot flash zip C:\adb\firmware.zip

Got this:

Repeat the same command: !! IMPORTANT !! -- PLEASE WAIT A FEW SECONDS BEFORE ISSUING THE COMMAND AGAIN; Otherwise the cmd prompt will be non-responsive saying "Sending data...", If this happens, try disconnecting the USB cable and reconnect.

fastboot flash zip C:\adb\firmware.zip

Note:The green bar on the phone may not go to 100% of the bar ... but If you see completed on your computer command window, wait for a few seconds and move on.

Last Step:

fastboot reboot

Then I went back to the bootloader mode (after the phone reboots successfully):

If Boot-Loop Occurs*:

fastboot erase cache

Restart in boot-loader to check whether everything is fine*:

adb reboot bootloader

--Phone reboots into bootloader--

fastboot getvar all

The resulting variable may look like this:

INFOversion: 0.5
INFOversion-bootloader: 1.56.0000
INFOversion-baseband: 4A.23.3263.28
INFOversion-cpld: None
INFOversion-microp: None
INFOversion-main: 4.19.401.9
INFOversion-misc: PVT SHIP S-OFF

INFOsecurity: off

all: Done!

Q: Do I need S-OFF for firmware flashing?

A: YES, It is a must.

Q: Do I need to update my firmware?

A: NO, but updating firmware ensures optimal phone performance.

Q: Does it matter when I flash the firmware (before or after new ROM install)

A: No.

Q: Will updating the firmware erase my SD card or Apps?

A: No, The firmware files provided here does not erase none of those.

Q: If I only flash the ROM, will I get updated to the latest firmware?

A: No. You must flash the firmware separate in most cases.

Q: Can I install a UL edition firmware on a U edition phone?

A: Yes (may be), but you won't have LTE or may experience some other incompatibilities.

Possible Errors while flashing:

If it says "FAILED" do not immediately reboot the device. If you reboot with a FAIL it could brick your device! Listed below error are safe to reboot:

If you encounter one of them, you can just reboot. Nothing changes.

- 12 signature fail (means a signed firmware package is required. This would only happen with S-ON phones though. but safe to reboot)

- 23 parsing image fail (means something wrong with the image in the zip)

- 32 header error (means the zip couldn’t be read and unzipped properly)

- 41 Wrong Model ID (means the MODEL ID in the android-info.txt does not match with your device. you can reboot the device. You may change the MID manually in the android-info.txt at your own risk.)

- 42 Wrong Customer ID (means you need to include the CID of your device in the android-info.txt or change the CID to superCID.)

- 99 UNKOWN (is not yet clear but safe to reboot)

DON'T reboot until you get a success message if you get an error bellow:

- 90 hboot pre-update (means it only flashed hboot and you have to run the process again immediately to flash all other partitions. Don’t reboot before repeating the command. If the command window stuck in the middle for a long time, wait for a few minutes and please unplug the USB and replug it again. Repeat the command again. DON'T reboot until you get a success message.)
​

Editing android-info.txt​

​

- Use an Editor that doesn't doesn't alter the linebreaks. Don't use Windows Notepad. Use Notepad++

- Only one MID can be in the file.

- CID's can easily be added or removed- one per line

To Get SUPERCID​

​

fastboot oem writecid 11111111

RUUmode:​

​

RUU Mode is the mode used for RUU flashes by HTC. It is different from the normal fastboot. You must flash the firmware only in RUU Mode. The RUU mode can be identified by the black background with only a silver HTC logo and if a command is being active a green progress bar will show the progress of any command being excecuted.

- Mike1986 Partition explanation:

​

You must be aware that writing to the bootloader -partition increases your risk to lose the device exponentially. You understand and agree that i cannot be held responsible for such or any other damages. The flash process is theoretically safe and tested. I will not accept any responsibility. The method itself is developed by Google and HTC, i have only adapted it and you execute it. You understand that you should not do it if you are not willing to accept this risk.​
