Hi guys
I want to update my hboot in order to install Jb roms. My current rom is a costum one.
My hboot is: 0.43
my build number ( I got this in menu>settings>about) : 2.17.401.2
And in fast boot when I run ''fastboot getvar version-main" I get this: 1.26.206.2
I have downloaded this RUU: RUU_ENDEAVOR_U_JB_45_S_HTC_Europe_3.14.401.27_Radio_5.1204.162.29_release_298897_signed
I do this things:
Install a stock recovery
relock phone
Run RUU and extract rom.zip from temp but I can't extract it completely and I get the corrupted error ( In order to get recovery, boot.img and system files)
I continue the installing RUU process and i get [132] error, "update signature failed"
I don't know what eles should I do
Can anyone help please?

that is because thats the wrong RUU for your phone you need the O2 2.17.206.xx RUU first then you should be able to install jelly bean from there. i hope this helps
Download this RUU
http://www.htcruu.com/securekey.php..._Radio_1.1204.90.13_release_251230_signed.exe
Now put the phone in the bootloader / fastboot usb mode and lock your bootloader ( if it is not locked)
Fastboot oem lock
After this you keep the phone in the bootloader / fastboot usb mode and right click the RUU.EXE file on the pc and select
RUN WITH ADMINISTRATOR RIGHTS (or the similar command )
Reboot the phone and start updating by checking for updates in settings - software
Can someone just confirm that this is the correct process for updating the HBOOT on my HTC One X from 0.95 to 1.3x (I'm unsure about step 5 & 6)
1. Determine the CID of my phone using
Code:
fastboot oem readcid
The phone reports
Code:
cid: HTC__001
which according to this means it is a HTC-WWE.
2. Download the latest HTC One X ROM from HTCdev which is endeavoru-jb-crc-3.1.10-e8d900a.zip
3. Copy the ROM to the phone
4. Relock the bootloader using
Code:
fastboot oem lock
5. Go into fastboot mode and type
Code:
fastboot oem rebootRUU
6. Flash the new firmware using
Code:
fastboot flash zip endeavoru-jb-crc-3.1.10-e8d900a.zip
On first time running the command will report FAILED, don't panic and just run the command again.
7. Reunlock the bootloader via HTCDev.
8. Flash a custom recovery using
Code:
fastboot flash recovery recovery.img
9. Download the CM10.1 ROM & extract the boot.img from the zip
10. Boot into recovery & install the ROM
11. Install the Google Addon
12. Boot into boot loader using
Code:
adb reboot bootloader
and use fastboot to flash the boot.img
Code:
fastboot flash boot boot.img
.
13. Use
Code:
fastboot erase cache
14. Reboot and enjoy
Warning
At 2 step, you have to donwload the zip from here and not the source of kernel!!!
And in 6 step you have to use: "fastboot flash zip "name_of_zip.zip"
Don't forget that you will have to unlock your bootloader at the end of all this (assuming you want to do that) and this will probably erase all your data again so back it up, including the SD card.
There is a firmware flashing tool in the development section that makes it easy!
I've found a post here which describes the procedure step by step.
UPDATE HBOOT FOR JB
1. You need your Unlock_bin from htcdev.com to re-unlock ur bootloader so please before u
proceed make sure u have this. Then reboot bootloader, and fire up CMD on your PC (start ->
execute -> cmd) and cd to ur fastboot directory
2. fastboot getvar cid or if it fails fastboot oem readcid will give u the cid of your phone
3. fastboot getvar version-main will give u ur actually RUU version
4. Now we have software version and CID. Time to get our RUU ->
http://androidfiles.org/ruu/?dir=Endeavor
5. Download the RUU for ur Phone (u need a higher or equal version then getvar version-main
reported
6. Place the .exe on ur PC and now we will extract the .zip (the rom.zip what is known as the
RUU) out of the .exe
7. Follow this tutorial: http://www.freeyourandroid.com/guide/extract-rom-from-ruu to get
the .zip out of the .exe
8. rename the .zip to whatever u like and place it in the fastboot folder of ur pc
9. boot phone in bootloader
10. lock bootloader with fastboot oem lock
11. reboot bootloader, and fire up CMD on your PC (start -> execute -> cmd) and cd to ur
fastboot directory.
12. bring phone into RUU mode: fastboot oem rebootRUU
13. fastboot flash zip rom.zip (u extracted and placed it before in ur fastboot folder)
14. In most cases this fails the first time. So redo fastboot flash zip rom.zip (this step costed me
2 hours because i didn´t know that)
15. boot into system when finished and if the version of the RUU isn´t allready on Jellybean
make all necessary OTA updates until u reach latest hboot (1.36, 1.39)
16. place the Unlock.bin which u got long time ago from htcdev.com (and hopefully u haven´t
lost it) in fastboot folder
17. reboot into bootloader
18. fastboot flash unlocktoken Unlock_code.bin
19. Ur bootloader is unlocked again
20. Congratz... u sucessfully updated ur hboot

You can do as you described using the file I linked...
without use a ruu

Does that mean if you flash the exact matching cid file from your link you don't have to follow the steps above? re relocking the phone and unlocking etc?
Why the heck are you trying to flash the kernel source in fastboot? There are instructions everywhere and in none of them say that you must go near kernel source
If you just want to update Hboot:
1. relock bootloader 'fastboot oem lock'
2. check cid: fastboot getvar cidnum
3. download firmware.zip from here: http://forum.xda-developers.com/showthread.php?t=1957376
4. in fastboot mode, type: fastboot oem rebootRUU
5. flash the firmware.zip using: fastboot flash zip firmware.zip
6. Reunlock your bootloader: fastboot flash unlocktoken unlock_code.bin
7. reflash custom recovery: fastboot flash recovery <name of recovery.img>
If you want to install ROM after:
8. flash boot.img of ROM
9. go to recovery and flash ROM
10. done

No.
You have to use this procedure, but whit the firmware.zip that you can found at the link i linked, and not whit kernel source.
If you see the OP, you can see that he want upgrade his hboot with kernel source, and he's wrong.
You have to use the firmware.zip that you can found at the link that i have linked.
All the rest of procedure is right
Managed it gents . Now on HBoot 1.39.0000 thank you very much for all your help. Really appreciated:good::good:
I have a HTC One X which has a T-Mobile firmware, CID: T-MOB005. Several months ago it was not possible to flash this device, has this now changed?
yeah it has....i've got the same CID and the JB firmware has been released
Can you point me i the direction of the right tutorial?
Do I need to S-OFF or change me CID for custom roms?
S-off is not needed, its as we speak even impossible to obtain .....
But you can go here for your firmware
http://forum.xda-developers.com/showthread.php?t=1957376
Read it carefully !
afford ganisava
I found the right firmware, but can't find the instructions.
Rename the .zip to firmware.zip and place it in the fastboot folder
- Boot the phone to the bootloader and relock the bootloader :
Fastboot oem lock
- then put the phone in ruu mode with this command
Fastboot oem rebootRUU
(watch the capitals, this command will put the phone into a black screen with a silver HTC logo)
- then flash the firmware
Fastboot flash zip firmware.zip
- you see the text on the pc screen, when it says OKE you are good. If it failed you reflash the zip right away again.
Then reboot the bootloader, unlock it, flash the custom recovery, make a full wipe and install the new JB of ypur choice and don't forget to flash its boot.img too
Hi, I'm trying to install cm10.1-RC5 from Arch Linux. I've wiped and factory reset and flashed the boot.img. I don't have s-off.
When I try to install the .zip in ClockworkMod 5.8.4.0 I get errors indicating that my bootloader isn't a compatible version. For example:
assert failed: getprop("ro.bootloader") == "1.31.0000"
E:Error in /sdcard/cm-10.1.0-RC5-endeavoru.zip
(Status 7)
Installation aborted.
I gather that this means my hboot or firmware needs an update. I've found this thread which seems relevant:
http://forum.xda-developers.com/showthread.php?t=2241419
I ran "fastboot oem readcid" and got this:
...
(bootloader) DEBUG: cid: VODAP021
OKAY [ 4.075s]
finished. total time: 4.075s
So I guess this means I need Vodaphone specific firmware? Where can I access this?
Or am I on the wrong track?
Post the result of fastboot getvar version-main..
This is a cmd fastboot command (windows)... No idea what's the command for Linux.. Might be something similar..
This way we can make sure which firmware you have...

This pointed me to .zip containing hboot 1.36.
I tried following these instructions:
http://sadevil.org/blog/2012/12/23/manually-flashing-an-ota-update/
Unfortunately the directories the tutorial references are different to the one in my .zip.
Now there are 2 ways you can upgrade your device's hboot
1: Returning to stock with a ruu and then updating to jellybean hboot with ota update.
2. Flashing the firmware zip and then installing a custom rom.
For running a ruu you will need access to a windows pc since it's an exe file : http://bugsylawson.com/files/file/1...11-radio-1120410514-release-260561-signedexe/
If you want to upgrade your firmware by flashing... Here's the firmware upgrade for your cid : http://goo.gl/yAa0G
Download the firmware and rename it to firmware.zip and then put it in the fastboot folder..
Steps:
1. Relock bootloader : fastboot oem lock
2. Reboot to ruu : fastboot oem rebootRUU
It will take you to a black htc screen... Wait for a few seconds for the screen to settle down and then flash the firmware :
Fastboot flash zip firmware.zip
You might need to flash the firmware twice if you get an error the first time! Its quite normal! After successfully flashing the firmware, you need to unlock the Bootloader, flash a custom recovery and then flash the custom rom!
PS: Again, the commands are for fastboot cmd (windows).. Linux might be a little different..

Your sequence is a bit mixed up. You should have updated firmware (hboot, radio, etc.) before unlocking bootloader. As you'll now have to relock the bootloader in order to update firmware. Then unlock it again, and TWRP again, to install custom ROM.
You also do not need root to flash custom ROMs (just need unlocked bootloader, custom recovery, and right firmware); unless you had another specific reason to root first?
Also, you will want all the updated firmware, not just hboot. As firmware contains a bunch of modules besides hboot, which will not play well with current ROMs (especially WiFi, Bluetooth, as well as radio and others). All the firmware installs in one zip, so it's not hard to do.
However, I agree with the previous post that we need more info on the phone. Fastboot getvar all, and post the results (delete IMEI and serial number before posting).
"At&t international version" is a contradiction. It's either one or the other, it can't be both.

Here's something I just learned recently (2 or 3 mos ago), although I haven't been able to test it myself since my M8 is S-Off.
When flashing an RUU.zip or signed firmware.zip from extSD instead of from your PC, relocking your bootloader isn't necessary.
Like I said, I haven't confirmed it myself, but the person who told me that I consider a reliable source. He was positive about it with M9, and quite sure it was the same with the M8.

As suspected, you need to update all the firmware, not just hboot. Your firmware is still on the original 2014 release of Kitkat. This will cause many issues, even if you updated hboot. For instance, you would find WiFi would be broken on just about every current custom ROM around; due to the WiFi firmware partition on the phone being outdated, and not compatible with the current ROMs.
ahmed has the process outlined well. I would recommend to follow his instructions above.

remove serialno from the getvar result in your post above
i don't know what you want
you need the latest firmware to flash a custom rom or you need to flash the latest stock rom ( by using RUU ) ???
in all cases you need to flash the latest firmware first 6.20.502.5 ( it's the latest firmware for your AT&T device variant )
6.20.502.5 is marshmallow and it's the latest official OS for this device
note :- flashing the signed firmware will wipe your internal storage so make sure to backup your files
flash firmware
1-download this signed firmware https://mega.nz/#!XV5EjYhS!gNN_rAYovaMQpaeP2OSdkfYAIEAmv6VnB-QlZ1VadMU ( rename it to something short and easy if you like )
2- open a cmd window in the folder where the firmware located
3- relock the bootloader ( if it's unlocked ) by this commands
fastboot oem lock
fastboot reboot-bootloader
3- now start flashing the firmware using this commands and replace firmwarename with the actual firmware name
fastboot oem rebootRUU
fastboot flash zip firmwarename.zip
if you see FAILED (remote: 90 hboot pre-update! please flush image again immediately)
then repeat the flashing command again
fastboot flash zip firmwarename.zip
after it complete type
fastboot reboot-bootloader
flash custom rom
now you have the latest firmware if you want to flash a custom rom unlock the bootloader and flash twrp then flash the desired rom

This command doesn't work on the M8, it's not even worth trying. The whole point of the HTCDev.com bootloader unlock process, is due to the fact that HTC forbids unlocking the bootloader with that command. It only applies to certain devices.
You need to use the bin code command. If it doesn't work, just request a new bin code, like ahmed suggested.
