you installed an OTA?

I'm using a Stock from a recovery Nandroid, not mine but the same CID 044... I guess I shold go back to RUU...but I've tried without any success

I can't even use my RUU file...donno why... I have this file: (RUU_ENDEAVOR_U_ICS_40_hTC_Asia_WWE_1.29.707.11_Radio_1.1204.105.14_release_260743_signed) and It works, not now but It used it once...do you have a suggestion so I can use it again??

you are on JB now and you can't run ICS RUUs, you can't downgrade...

I'm not...I'm on 2.17 yet...JB update does not install...that's the main problem
and I have noticed that NO MATTER I CHANGE...IT WONT CHANGE THIS VERSION... OMG
tks man!

You need to relock your bootloader (if you haven't already) and run THIS RUU.
The problem is that the version of software you're running (2.17) is newer than the RUU you're trying to install (1.29). you can't revert to an older RUU. you can only flash the same version or newer.
Once you've flashed the RUU, you'll be able to download and install the JB OTA.

Thank you very much man, You renew my faith!!
It will work like a FORMAT SYSTEM with the same Rom?
I'll keep in touch!!

Also, this may sound silly but did you reflash stock RECOVERY?

You don't need stock recovery to flash an RUU. You just need a locked or relocked bootloader, and a less or equal main-version.
Once you run an RUU, you will have stock everything(including recovery) and will be able to install whatever OTAs are available.

Well I am currently running Team Venom's Viper but I have HBOOT 1.31. My device's CID is HTC_J15.
I have checked the list of RUUs but unfortunately all of them are older than the version I need, which has to be 3+.
Does anybody know if there's an RUU available for my device? It is an ubranded WWE version, 401 if I remember correctly.

In my experience the 2.17.707.xx RUU Asia WWE does not work properly. It does its thing installing everything, relocks the bootloader but somehow it does not reflash the recovery. After 4 hours trying everything under the sun, I gave up and looked for a nandroid of 2.17 for CID_044 and restored from that, reflashed stock recovery and went to town with the OTA.

That's very strange, no such problem when I did the same thing. You'd think it would throw an error or something if a component of the image failed to flash.
Glad you managed to figure it out!
Did you run it when your bootloader was unlocked? Maybe that's the problem? I ran it with the bootloader relocked and didn't ahve any problems. I was under the impression you couldn't run an RUU with an unlocked bootloader, but haven't tried it myself.

Refer custom to stock thread posted earlier. Go through step by step procedure. It will help u to be on stock Rom. After that flash any Rom suitable to your CID only

Got It guys!!
What I did... NOTHING else...
Only Reboot the phone...wait to initialize completely, then reboot again, when came a little update about 1.25mb...installed and reboot...after that...JB update installed correctly.
If someone else needs...Someone like me who relocked the phone waiting for JB and Has problems
1. Unlock Phone
2. fastboot flash recovery recovery.img (from nandroid 2.17)
3. fastboot flash boot boot.img (from nandroid 2.17)
4. fastboot erase cache
5. restart bootloader (I like to do this way)
6. Install RUU_ENDEAVOR_U_ICS_40_S_hTC_Asia_WWE_2.17.707.3_Radio_2.1204.135.20_release_278245_signed on windows
7. Wait to boot completely, then restart phone.
8. Update Software ...a little update came before JB. (about 1.25mb)
9 Reboot phone.
10. Update Software... finally to JB.
Thanks guys!

The RUU ran with no problem, and it relocked my bootloader, but it still did not receive any OTAs. So I had no choice but to do a nandroid restore instead (recommended anyway )

[Q] HTC One X JB rom upgrade - newbie

Hi Guys,
i am completely new to Android, had my One X for 6 months now.
i really want to upgrade to JB, the renovate ROM.
i have CID_016 and HBOOT 1.12.
can any1 tell me the steps i need to take, i will do my best to find the detailed instructions on each step.
but i just need to know exactly what i need to do...upgrade HBOOT? if so what version? if im on 1.12 - do i have to do 1 or 2 version before going to the final version etc...etc
i really dont want to brick my device.
thanks

Okay first thing I would do is have a look at the renovate ROM thread, because the OP would most likely be a nice person and have some instructions. Let's see what they write......
http://forum.xda-developers.com/showthread.php?t=1705334
"How To Flash:
For the Jellybean update you need to have flashed the updated firmware. Please have a look at the many guides available on how to do this"
Oh, so they want us to flash updated firmware, how should I do this? Well look! Conveniently stickied is a thread called "[07.12.2012] Jelly Bean firmware collection for different Carriers ID (CID)", let's go there!
http://forum.xda-developers.com/showthread.php?t=1957376
Oh I see my CID number listed underneath!
I will then proceed to download the firmware.zip file.
Okay I downloaded, now what? Well let me scroll down the page and see if there are any instructions:
"Flash firmware.zip using following terminal commands:
fastboot oem rebootRUU
fastboot flash zip firmware.zip"
Okay, I see I have to be in fastboot mode in order to do this. But I must not forget to relock the bootloader first. So I use the command 'fastboot oem lock' to first lock my bootloader, and then proceed to complete the above instructions to flash the firmware.
Okay now what? Well I think I should relock my bootloader now that I want to flash renovate, so I do by using 'fastboot flash unlocktoken unlock_code.bin'. Done.
Next, ...........
Or seriously just use this tool: http://forum.xda-developers.com/showthread.php?t=1924003

You need either HBOOT 1.31, 1.33 or 1.36 for this ROM.

So...yes U have to upgrade your HBOOT.
All other steps for flashing are described in every rom thread.

thanks tomascus - that last link is what i needed.
i know there are detailed threads on the ROM links, and i cant ask questions on there, so just wanted to know about what order to do things, and if i needed to upgrade my HBOOT to some other version first before going to the latest etc...dont ahve money for a new phone so dont wanna brick it
i've already downloaded firmware with HBOOT 1.36, as well as a custom ROM, busy downloading JBFWTOOL now.
can i go straight from HBOOT 1.12 to 1.36? running ICS obviously
thanks a mil.

last question, i hope - what is this "unlock_code.bin" that i see certain instructions talk about?
in bootloader it says "S-ON" - do i need this unlock_code.bin and if so how do i get it?

You get it when you unlock at htcdev. You will need it when unlocking bootloader.
S-ON has nothing to do with this don't worry about it.

Yes, at the moment you can't do anything without unlocking the bootloader at htcdev.com.
And I really recommend this tool for unlocking and installing custom recovery, it truly is noob-proof.
After using that tool you will have all pre-requirements and tools needed for installing custom roms. :good:

[Q] Hboot and ROMs

Hi everyone, two really quick n00b questions...
Do you have to upgrade Hboot from say 1.21 to 1.39 etc if you want to run a new platform (Jelly Bean) Sense ROM?
And you don't have to upgrade Hboot to get a AOSP Jelly Bean ROM?
The reason I ask is because I'm trying to figure out if Hboot is directly linked to Sense ROMs, it's because I've just read this thing saying you have to update Hboot to get JellyBean on your HOX... but I'm running CM10 on my HOX with Hboot 1.21 (I think...) lol.

With hboot 1.39 works all Sense rom and CM10.1 rom based.
For CM10 you need a special boot.img

hi there
another hboot question, i am on 1.12 and would like to upgrade, which hboot should i choose ?
i thought to relock my hox with my stock nandroid backup and then upgrade by ruu or ota by htc. should i upgrade with ruu or ota htc ?
thanks

All CM10.1 works fine, CM10 needs a special boot.img.
For upgrade your firmare:
- Relocked your bootloader
- Copy/paste the firmware in folder where you have fastboot
- Open a prompt and type: "fastboot oem rebootRUU" (you can see a black screen with a white written)
- Type: "fastboot flash zip firmware.zip", you can have an error, retype and it will work
- Type "fastboot reboot-bootloader" and you can see you hboot updated
- Unlock your bootloader
- Flash a recovery
- Flash a rom

hey, grazie mille for your hints, amigo.
now i need some thc to flash my htc, first i have to fully recharge my htc before work around with it. i will let you know if i have a brick or upgraded hboot

If you upgrade to 1.39, you can't downgrade because there isn't the s-off.
But if you want jelly, you have to upgrade and, however, you can use ics rom with new hboot
But not CM10, this rom need a special boot.img with new hboot

[Q] Can't flash the device to stock rom using RUU

Hi,
I'm trying to restore from custom rom to stock rom.
My phone is CID ORANG216 and I'm using xx.xx.65.xx RUU releases.
I have 2 relevant files:
The RUU exe - RUU_ENDEAVOR_U_ICS_40_S_Orange_CH-Generic_2.17.65.2_Radio_2.1204.135.20_release_275590_signed.exe
OTA UPDATE for the device - OTA_ENDEAVOR_U_JB_45_S_Orange_CH-Generic_3.16.65.2-2.17.65.2_release_296426gf2xgpisn8xs0fti
After flashing the stock recovery, boot_signed.img, rebootRUU, the RUU update fails because of version failure, I suspect that the HBOOT version is the trouble maker.
My phone is unlocked with S-ON with HBOOT 1.36 and the HBOOT in the RUU is 1.12 .
Due to S-ON I cant change the hboot.
I can't seem to find a workaround for it and install the RUU.
Any ideas??
I even thought about compiling the latest JB release from htcdev development center and flash it...

You need to relock the bootloader to use install RUU . It has nothing to do with hboot . Just take note that you have to use the RUU that is on the same build or higher .

Like I mentioned . You have to look for the version that's the same with yours or higher to use the RUU . I guess you can't go back to stock until you find the RUU of your version or higher . Maybe you could try a stock ROM nand backup ?

I don't think your questions relate to the subject here.
Anyway, custom roms are based on the stock rom and most of the times include a file called firmware.zip, look it up in the costum_rom.zip file.
hboot updates are tricky on this device and for upgrading it (from ICS to JB supported hboot) you need a special firmware built for your specific htc one x model (look at the manuals for more instructions).
For the battery saving, I think it depends on the rom you install and not the kernel (or maybe both because they come together?), check out for old posts about that issue, I'm sure its not the first time someone asks about it.
hope it helps

Also, I am a complete novice with all this stuff so you may need to "dumb down" your answers a bit Thanks in advance.

The reason I'm trying to do this is because I'm on CyanogenMod 10.1 and the 10.2 update (Android 4.3) requires the newer hboot, so how would I go about doing this myself (step by step)?
Also Tigerlight, I'm fairly confident that JB FW doesn't let you use non Sense based ROM's afterwards, and to be honest I prefer doing things like this myself rather than letting software do it for you

Well...
You should be able to have CM 1.2 on 1.39...
But you Will have to wait for the firmware zip to be uploaded here http://forum.xda-developers.com/showthread.php?t=1957376
in order to be able to update it manually... You could download the OTA files and extract that firmware.zip yourself and than find a tutorial on how to flash a firmware.zip... there are plenty of them out here

JBFW flasher upgrades hboot, which has nothing whatsoever to do with what Sense or AOSP ROM you flash afterward so long as that hboot is compatible.
And why on earth type all the instructions manually when the tools exist.
And the 1.72 hboot firmware has been uploaded HERE.

Ok, may have been a bit wrong there..... :silly: Still, I like to learn how to do this sort of thing so that if anything ever goes wrong I have the knowledge to fix it. Once I have the firmware, what do I need to do?

Just downloaded JBFW out of interest, and when you go to update it says this: After upgrade you will not be able to - Install a fully functional Non-Sense ROM, so I was right that I can't use that software, and anyway wouldn't want to tbph Anyone know how to manually update hboot given that I have no files from when I rooted anymore? :laugh:

Once you have the firmware.zip file you have to
1:relock the bootloader
Fastboot oem lock
2: boot into ruu mode
Fastboot oem rebootRUU
3: flash the firmware.zip
Fastboot flash zip firmware.zip
Maybe needed twice (only if the command returns an error)
Then unlock the bootloader and flash a custom recovery. Preferably repacked twrp, or philz touch recovery.
Then full wipe the phone in recovery and install the rom.zip and fastboot flash the boot.img.
That sums it up pretty much

Once you have the firmware.zip file you have to
1:relock the bootloader
Fastboot oem lock
2: boot into ruu mode
Fastboot oem rebootRUU
3: flash the firmware.zip
Fastboot flash zip firmware.zip
Maybe needed twice (only if the command returns an error)
Then unlock the bootloader and flash a custom recovery. Preferably repacked twrp, or philz touch recovery.
Then full wipe the phone in recovery and install the rom.zip and fastboot flash the boot.img.

Thanks Mr Hofs,
Already found out about 20 mins ago: you actually responded to someone else a while back and I used those instructions. I may have messed up quite a lot though: forgot to put the CM 10.2 zip on the phone before hand and now the phone is acting really weird..... I'll let you know if I need help but I have a few ideas first
Thanks again, I appreciate the help.
