this procedure to change mid is very outdated and there is now much easier and safer way to do it with a tool from custom recovery.
Just to be sure, you were doing this procedure to change mid right?

you should still be able to use fastboot commands from that gray screen. So do that commands:
Code:
fastboot getvar all
copy/paste or post a screenshot except the IMEI and Serial #. See the example below:
The output of ''fastboot getvar all'' is required to determine what are the possiblities to restore your phone. I'm assuming here that you know how to use fastboot because you have used it previously to flash the eng hboot.

baseband is your radio. It will be flashed back with a ruu.
latest dev edition ruu: http://www.htc1guru.com/2014/03/android-dev-ruu/
latest GPE ruu: http://www.htc1guru.com/dld/ruu-zip-m7_google-edition_4-4_3-58-1700-5-zip/
For the ruu.exe(DEV edition), just lauch the .exe file with phone in bootloader.
For the ruu.zip (GPE)
boot phone in bootloader
make sure the ruu.zip is in the same folder of adb and fastboot
Code:
fastboot oem writecid GOOGL001
fastboot reboot-bootloader
fastboot oem rebootRUU
fastboot flash zip name_of_file.zip [COLOR="Red"]---> will fail first time and ask you to ''flush'' image again immediately
[/COLOR]fastboot flash zip name_of_file.zip [COLOR="red"]so do the command twice. There's no progress bar, this can take up to 20 mins[/COLOR]
fastboot reboot
Just a side note:
If you are going to use the GPE ruu, NEVER turn security back to S-ON and NEVER relock bootloader :angel:

you should be able the use adb commands from recovery to push the rom to your sdcard or use adb sideload method.
Code:
adb push name_of_rom.zip /sdcard/
then in twrp select ''install'' and choose your rom, swipe to install.
or use adb sideload: http://forum.xda-developers.com/showthread.php?t=2318497
btw I suppose you meant ''software (rom)'' not ''firmware''. Firmware is not flashed trough recovery and don't need to be on the sdcard to be flashed. (flashed via fastboot)

do you have the android sdk installed on your computer? You will need it, its the base. I supposed you already know about adb/fastboot commands because you said you were running a custom rom which require adb/fastboot to unlock the bootloader and flash a recovery... TWRP is a custom recovery, you said you wiped everything from recovery... which recovery are you using?

[GUIDE] Return to Stock with hboot 1.56+ (M7) - Telstra Australia (no ruu avail)

Due to the massive inconvenience/time this has caused me, having little experience initially with android devices and coupled with the fact Telstra Australia will not release an RUU to make things easy, I thought I would document my method for those currently on hboot 1.5x+ who are wanting to roll their device back to complete stock. This process is specifically for people who want a Telstra branded rom for warranty and does require sunshine if you have hboot 1.57. This is for the HTC one M7 although I suspect the process is the same on the M8..
This method was performed in Windows 7 as Windows 8 seems to have issue with fastboot commands. If you have a different carrier, are performing this on Mac or plan to use a Nandroid please see nkk71’s superguide for more details. Unfortunately the only 2 Telstra Nandroids I could find both failed for me.
*Please make sure fastboot is unchecked and usb debugging is turned on in developer options
I have packaged all of the tools needed including the RUU.zip I used in the link below. The Guru files are hosted separately.

1. S-off must be achieved. If you have it already you are in luck, proceed. This table also appears in nk771's superguide showing what you can or cannot achieve with S-off for reference.

Methods:
a) If you’re on hboot 1.44 use revone -

http://revolutionary.io/
b) If you are hboot 1.54/1.55 you can attempt rumrunner

http://rumrunner.us/
c) If you are in hboot 1.56/1.57 you will need sunshine for $25usd as I did. As far as I am aware there is currently no way around it. However I am very happy with this application and support. Firewater is discontinued.
http://theroot.ninja/
2. Reboot into bootloader/fastboot usb and perform getvar
fastboot getvar all
Note the following:
version-bootloader: 1.57.0000– hboot version
cidnum: TELST001 - CID
modelid: PN0714000 – MID
version-main: 5.11.841.9 – firmware
All Telstra devices should have a modelid of PN0714000. If for some reason you do not have this MID see nkk71’s superguide for different MID/CID RUUs and download a different version.
BOOT LOOP
The firmware will be reset to a 1.29.x base when you flash the RUU which is fine for OTA updates. If you have previously experienced boot loop it is because the firmware coming out in the OTA updates is lower than the firmware already installed on your device. Firmware can only be upgraded not downgraded by OTAs.
3. Provided your MID is PN0714000 proceed to change your CID to match RUU CID. The CID associated with the RUU provided is HTC__044
fastboot oem writecid HTC__044
fastboot reboot-bootloader
*confirm CID is now HTC__044 – see bootloader or getvar
4. Flash the RUU.
fastboot oem rebootRUU (silver htc will appear)
fastboot flash ruu.zip (it will report failed flush, repeat command)
fastboot flash ruu.zip (success)
fastboot reboot-bootloader
*bootloader should now read hboot 1.44
5. Change CID back to stock (TELST001)
fastboot oem writecid TELST001
fastboot reboot-bootloader
6. Mount and Launch TWRP custom recovery
fastboot boot openrecovery-twrp-2.8.4.0-m7
7. Once in TWRP your phone become available as a mass storage device. Run an ADB command to check the phone is being recognized in windows and then push the guru reset rom to the device.
adb devices
adb push Guru_Reset_M7_2.24.841.1.zip /data/media
If your device does not display a serial number executing an adb devices command you will need to install the drivers in device manager, it is likely an unrecognized device post RUU flash. See nk771s FAQ for instructions.
8. In TWRP recovery hit install, navigate to the data/media folder and select the Guru_Reset_M7_2.24.841.1.zip
Run through the installer and select the options as seen in this video
https://www.youtube.com/watch?v=Gqfly8XVw6w
When complete hit – do not add root and reboot the device. If it gives option to wipe cache, do so.
9. Boot your phone as normal into the now stock 4.2.2 Rom, set up wireless and install the first two small OTA updates to confirm they are working. If successful uncheck fastboot/enable usb debugging again and reboot phone back into boot loader with adb command.
abd reboot bootloader
10. In fastboot USB mount/launch TWRP recovery then adb push the Guru Boot Loader tool to the device.
fastboot boot openrecovery-twrp-2.8.4.0-m7
adb push Guru_Bootloader_Reset_1.0.zip /data/media
11. Hit Install, Navigate to the folder and launch Guru_Bootloader_Reset_1.0.zip. Run through the wizard and select remove tamper and lock function then wipe cache. Video here for clarification.
https://www.youtube.com/watch?v=yimzmt23E6Q
12. Reboot the phone a few times into bootloader to make sure lock/tamper does not return
fastboot reboot-bootloader
If unlocked/tamper returns or the installer fails you may have to use the manual method, exercise caution. See nk771's FAQ for instructions.
13. Set S-on
fastboot oem writesecureflag 3
fastboot reboot-bootloader
Fastboot into bootloader a few times to make sure everything is fine before proceeding to final OTA updates.
14. Boot phone normally and proceed to do all of the remaining OTA updates to bring your software/firmware up to latest version. Sometimes the phone will boot into stock recovery mode first time after S-on, just reboot it, it will come good.
If you would prefer to use a Nandroid backup (although I am not sure why), start from step 7 and restore it via TWRP or CWM (depending on the backup type) in place of Guru Reset. After this is complete you can proceed with the remaining steps.
This all came about from Telstra being unwilling to repair my purple haze issue (which is clearly a sensor/camera module hardware defect) while having my bootloader unlocked/tampered. The purple haze issue occurred when my device was factory locked. I understand unlocking the boot loader voids warranty but this issue is hardware related which happens on stock software/firmware. I find it a little dishonest that HTC/Telstra want to charge me to have my unit replaced/repaired when it's a known hardware defect unless I am willing to go back through the process of making this device look like it's stock. I hope this can help some of the Telstra customers in the same position as RUU/Nandroids are almost non existent. Thank god for guru!

I checked the file on my onedrive and it appears to be fine. Does the rar fail to open once downloaded or you cannot download the link period?

Help with bootloader unlock

I converted this phone to Google play edition when it first possible to do so.
I relocked the bootloader and unrooted it and gave it to my sister in law.
Just got it back and need to replace the camera before I give it to my son.
I want to unlock the bootloader and root it and put twrp on it.
For some reason I have struggled to do so.

Well its a well known issue with the GPE bootloader (not being able to unlock it). Luckily your phone is already S-OFF so all you have to do is the flash a custom recovery in a masked firmware.zip (I made one for you that will flash twrp see attached files at the end of my post), boot in recovery. Then you can unlock the bootloader using an adb shell from twrp recovery so its easier to flash the recovery the next time.
so with your phone in bootloader mode and showing "fastboot usb" in red:
Code:
fastboot oem rebootRUU
this will get you in RUU mode, a black screen with a silver HTC logo.
Code:
fastboot flash zip firmware.zip
First flash will probably report something like "Flush image again immediately" so do the same command again:
Code:
fastboot flash zip firmware.zip
Make sure the command window report "Sucessful" then reboot in bootloader:
Code:
fastboot reboot-bootloader
Thats how you flash a custom recovery on a locked bootloader + s-off phone.
Now, from the bootloader menu, select "recovery" and once booted in twrp recovery (main menu) use these commands to unlock the bootloader:
Code:
adb shell
echo -ne "HTCU" | dd of=/dev/block/mmcblk0p3 bs=1 seek=33796
adb reboot bootloader
and confirm your bootloader is now unlocked.
Btw you should revise your commands, I see in the first pic you are making a lot of errors
fastboot oem read cid ----> fastboot oem readcid
fastboot write cid 11111111 ----> fastboot oem writecid 11111111

Well its a well known issue with the GPE bootloader (not being able to unlock it). Luckily your phone is already S-OFF so all you have to do is the flash a custom recovery in a masked firmware.zip (I made one for you that will flash twrp see attached files at the end of my post), boot in recovery. Then you can unlock the bootloader using an adb shell from twrp recovery so its easier to flash the recovery the next time.
so with your phone in bootloader mode and showing "fastboot usb" in red:
Code:
fastboot oem rebootRUU
this will get you in RUU mode, a black screen with a silver HTC logo.
Code:
fastboot flash zip firmware.zip
First flash will probably report something like "Flush image again immediately" so do the same command again:
Code:
fastboot flash zip firmware.zip
Make sure the command window report "Sucessful" then reboot in bootloader:
Code:
fastboot reboot-bootloader

Thank you, worked like a charm. Greatly appreciated.

Hard reset. What to do now?

So frist i did a usual factory reset and it just went recovery and like what happend before didn't do a clean reset, just apps gone and that's it. So i did it manually by checking all "partitions" including "Cache, Data, Internal Storage, System" and all. Now TWRP is all i got on my phone. I didn't know what i'm doing and it was a noob move, i know. But now i managed to copy a custome ROM (Viper One 9.0.0) to my sdcard via adb push command.
Now all i need is to flash it.
TWRP says "This operaion may install incompatible software and render your device unusable"
Is it safe to do so?
I also wanted to go back to Stock ROM and actually downloaded one from HERE. It's the one provided in METHOD 2 .
The only reason i want to flash Viper One again is that i flashed it before without any problem.
If i make sure that it's safe to flash the Stock ROM i'd do it. Please let me know what should i do. Thanks.

TWRP is 3.0.2-2
and btw, seems like i can't flash anything with twrp now. keep saying "zip signature failed"!

And please guide me through on how can i go back to stock rom safely.
Of course i can find tons of articles about it but there are few confusions and since it can end in a brick i can't risk it. For example is THIS ONE legit? for flashing RUU, is the one i mentioned above will do it? I mean THIS ONE
or if there's any better guide here (sure there's, i know!) please link it here. Thanks

Linked guide is for M8 and does not apply to your situation.
reflash the stock recovery, relock the bootloader and flash the 7.19.401.51 RUU
Code:
fastboot flash recovery M7_UL_Stock_Recovery_7.19.401.51.img
fastboot erase cache
fastboot reboot-bootloader
fastboot oem lock
fastboot oem rebootRUU
fastboot flash zip PN07IMG_M7_UL_L50_SENSE60_MR_HTC_Europe_7.19.401.51_Radio_4T.35.3218.16_10.33Q.1718.01L_release_458803_signed.zip
fastboot reboot
You must use this fastboot version at least for the "fastboot flash zip" command.

So it went all good till the "fastboot oem rebootRUU" command. It reboots and then htc logo shows up and nothing after that. I have to reboot it by Power+V- in order to go in bootloader again?
Is something wrong? Or should i run the next command there in bootloader?
P.S: Bootloader is relocked, by the way.

NVM. Just ran the command again and it's working now!

It worked man... AWESOME!!

Alright just one more question. If i ever want to root my device again, it will be ok?
And if you have the time, please link the right thread for it. Your work is much appreciated mate. Thanks a billion!
