Need Help Getting Phone to Boot!

Hey Guys,
I'm reaching the point of frustration now. To try and cut a long story short, I had the Android Revolution 6 ROM on my rooted/unlocked HTC One X, and decided to update it to Android Revolution 13. I followed all the instructions, went to boot it, and it just sat on the HTC logo for an hour at which point I knew something went wrong. I repeated the steps, including wiping data using super wipe, without success either. I then decided to just select the "Factory reset" option on the boot menu, but this has also failed to boot after 30 minutes. I can also no longer boot into recovery. I've tried reloading CWM and other recovery ROM's onto the phone, but the phone resets as soon as they load.
At this point, I just want to get some form of OS on my phone. My phone is Unlocked, S-ON and has a CID of OPTUS001. I don't know if Factory reset will work if the phone is unlocked. It's all very time consuming as you normally don't know if the boot process has locked until you've waited ~20 minutes. I can't find my original ROM from when I bought the phone either, so I assume I need to obtain another one from somewhere, but I don't have any idea about CID compatibility, etc, and I'm finding this all very confusing and frustrating. All help is much appreciated. I have a feeling I need to replace my boot.img with a stock boot.img, but once again, where do I get that?
Thanks

the phone doesn't boot because you don't have the latest firmware installed, you need HBOOT 1.31 but you can't install it cause your CID is not compatible with it, you sjould go back to ICS and wait...

Did you load new firmware 1.31? This firmware is not compatible with Your CID... Did You read carefully this thread — http://forum.xda-developers.com/showthread.php?t=1924003
Sent from HOX with ARHD 13

You forgot that you need to update the firmware to 1.31.
You can also just install ARHD 9.7.2. Ensure you have the latest CWM 5.8.4.0
faatboot flash recovery recovery.img
and then flash the boot image:
fastboot flash boot boot.img
fastboot erase cache
And then copy the ROM on using recovery mount USB and flash it.

Thanks for all the help guys. I managed to get a stock recovery.img back onto the phone, and by re-locking the phone I was able to use the latest Optus RUU from htcruu.com.
So at least I've now got a working phone again.
Moving onto why ARHD didn't work, I had no idea about the firmware 1.31 compatibility requirement. I thought all HTC One X's were created equal. I didn't know about this CID nonsense. Can someone explain how I find out when my phone's CID becomes compatible, or perhaps a way to change my CID or some other means of getting Jelly Bean onto my phone. Apologies for being a noob.

without S-OFF no chance to change CID. Regarding CID compatible - http://forum.xda-developers.com/showthread.php?t=1924003

Optus not compatible with JB yet

[Q] Updated to JB but no WIFI / BT /phone signal

Hi all,
Just spent the last six hours trying to get my One X onto JB- well I got it on finally but now have lost WIFI/BT/Data and signal.
I started with bootloader 00.93.0000 I think, then attempted to install JB. This didn't work... So I tried to upgrade the bootloader to 1.31.
I then installed RUU 2.17.401.2 Radio 2.1204.135.20 trying to revert the damage of installing JB with wrong bootloader and upgrade the bootloader thinking .91 was the reason I couldnt update using fastboot commands, it would always hang as it was pushing the file.
I think the above RUU gave me the wrong radio. (was asking for date/time on bootup)
I then used the JBFWTOOL which have me the 1.31 bootloader and then I reflashed Revolution HD 14.
I then installed revolution 9.7.2 thinking it was to do with JB but this hasn't worked either.
It worked the second time around but I have no signal/bt/wifi.
Device ID is HTC_001 s-on
Believe it was O2 but was unlocked I use a 3 sim card in it.
I can still get to the bootloader menu etc
I don't know what else to do. The RUUs wont work due to bootloader and I haven't found any info on just changing wireless packacges like you can with odin.
Please help!

you never mentioned flashing the boot.img
1- update bootloader(seems you already did) and unlock and install cust.recovery
2- flash the boot.img file included in ARHD's rom.zip from the bootloader, fastboot flash boot C:/location_of_boot.img_on_pc
3- install the arhd rom.zip from cust.recovery
Note: sadly since you have installed a new hboot (anything greater than 1.23) there is no way to use an old RUU (ICS), new RUU's wont be released anytime soon (unless leaked)
hence, i recommend properly installing your JB and stick with it, after all its much better than ICS , unless you experience one of the hardware bugs.
Once the newer (1.33) bootloader is released(should be this week), it should fix all currently known bugs, and then you are safe to flash use latest ARHD or Maximus Roms for daily use.

Return to stock 1.31.651.2 Sprint HTC One after root

OK, So after searching and Searching for a way to go back to complete stock after taking the latest 1.31 update and rooting my HTC One, and not being able to use any current RUU without having to gain S-off. I finally did it. I am 100% stock on an updated software version of 1.31.651.2.
So here is what I did and please feel free to step in and let me know if there was an easier way.
Step 1.
I unlocked my boot-loader to gain root privileges
Step 2.
I flashed TWRP
Step 3.
Created Nand Backup if something fails
Step 4.
I flashed SuperSU
OK, so that got me rooted. but I wanted to go back to stock after playing around with certain roms my phone started acting goofy.
this is the part where it gets a lil tricky.
in order for me to get back to stock on my One to the most current version of 1.31.651.2.
this is what I had done.I installed an app from the market called Rom toolbox lite(FREE) put REVONE in /data/local/temp
gained S-off. installed a stock RUU 1.29.651.7. Now the only problem is that I was S-off and my boot loader shows tampered and unlocked.so I used revone to remove tampered with the -t command and also wanted to lock the boot loader with the -l command. in order to get s-on. booted into the boot loader and selected fastboot and entered fastboot command, fastboot oem writesecureflag 3 to regain s-on.
ok so I am still technically rooted so in order to remove all root instances I ran again the RUU 1.29.651.7. all good so far. I double checked by booting into the boot loader to make sure I am s-on and locked along with no tampered flag. YES!!!!. so now I booted up my phone . skipped all setup processes. and went straight to the check for updates in the phone menu. I updated to the next most recent after the 1.29.651.7 and installed 1.29.651.10. I download and installed the update. again checking to see if there were any changes in the boot loader. NOPE STILL ALL GOOD,YESSSS!!!!
so now it rebooted and again went straight to the HTC update menu and ran a check for updates and it then downloaded the most recent update 1.31.651.2. Installed and I checked the bootloader and I AM NOW 100% STOCK and on the latest software version.

At least a Thank You ??

I was having the same issues when trying different Roms and screwed up my phone to the point where roms would boot but them restart over and over and over...no matter what rom i loaded and any kind of wiping i did.
so I also returned to stock locking the bootloader and flashing stock RUU as you mention. Just tried going from 1.29 to 1.31 with OTA last night and it wiped my phone and didn't upgrade. So i'm hoping it was just a hiccup and going to try again.
Hope it works this time.

Okay guys so everything you described is exactly where I'm at. I've tried a million ROMs, process, adb.exe (no devices), etc...... Anyway here's my scenario.... Exactly yours: got my phone, rooted it, had S-On. the phone ran it's updated to 1.31.651.2 so there are no RUUs for this. Any extra details to get me there?
Where should I start? Please let me know if you can help.

[Q] Why is my HTC One x (PROTOTYPE) stuck on ICS?

Why is my HTC One x (PROTOTYPE) stuck on ICS?
Hey guys, This is my first post ever on XDA so please forgive me if I sound like an idiot
I got hold of a HTC One x which was already had an unlocked bootloader, rooted and had CWM recovery installed. I was told that I have a prototype version of the one x. Anyway that is not issue. when I got the phone it was running android version 4.0.4 HTC Sense version 4.1 and I checked software update. The 3.14.401.27 OTA update was available so I proceeded with the update and after the reboot I found my phone stuck in a bootloop and the only way for me to sort it out was by restoring my nand back up from CWM. I really wanted the new Sense 5 UI and android jelly bean so I downloaded:
RUU_ENDEAVOR_U_JB_45_S_hTC_Asia_TW_3.14.709.20_Rad io_5.1204.162.29_release_292865_signed.exe
My CID was HTC__621 thats why I downloaded that ruu but after flashing it not was I only stuck in a bootloop but also when I entered recovery mode it was just a blank black screen with the back lights on. I even flashed different versions of CWM recovery and TWRP which gave me the same black screen so I flashed the stock recovery.img which also gave me the same black screen. I thought me maybe a different Ruu would resolve this issue so I used 'JBFWTOOL21' to change my CID to '11111111' this allowed me to flash:
RUU_ENDEAVOR_U_JB_45_S_HTC_Europe_3.14.401.27_Radi o_5.1204.162.29_release_298897_signed.exe
&
RUU_ENDEAVOR_U_JB_45_S_HTC_Europe_3.14.401.31_R_Ra dio_5.1204.162.29_release_302015_signed.exe
After trying both these ruu's I still found my device stuck in a bootloop. Next I downloaded 'Endeavoru_CustomRUU' this contained a 'rom.zip' which I belive was a jelly bean rom and said it would update my image version to '3.14.401.31' after flashing this ruu, my phone booted up past the 'HTC Quietly Brilliant' screen but into a black screen but I could hear the boot sound and knew it booted up but it still gave me a black screen. barre in mind this was the only rom that booted up and didn't get stuck in a bootloop but the downside was I had no picture on the screen it was literally pitch black with the backlight on when it went past the 'HTC Quietly Brilliant' boot screen. I didn't even see the one x boot animation. I could only hear the boot up sound and once it was booted up the notification LED would flash I was receiving network settings from my operator. That was about it. I booted into recovery to see wether that worked but unfortunatelly it was also still giving me a black screen. The only thing I could boot into without a problem was 'power button + volume down' which booted into bootloader in which I chose 'fastboot' to flash all these roms.
At this point I thought my device was soft bricked so I gave it to my friends father who happened to really good with his IT skills. He managed to change my device's CID from 'HTC__621' to 'HTC__001' after doing so he downloaded this ruu and flashed it:
RUU_ENDEAVOR_U_ICS_40_S_HTC_Europe_2.17.401.2_Radi o_2.1204.135.20_release_274900_signed.exe
This ruu turned out to work perfectly fine with my device. Everything functioned once again, the device was able to boot into recovery and boot normally without a hassle. I also discovered that this was the rom that I received my phone with which put me back to the start on android 4.0.4
I was really annoyed with the fact that I was stuck on ICS so I flashed the MaximusHD 21.1.0 rom and its boot.img which put me into a bootloop again. I also tried other custom roms such as Revolution and SD secxces which all put my phone in a bootloop even though I flashed their boot.img kernels. I knew that I required a hboot 1.33.0000 or above in order to flash jb roms so I used 'JBFWTOOL21' once again before flashing these custom roms to update my hboot from 1.12.0000 to 1.33.0000. so all these bootloops still occourd after doing all this and I just had to return back to ICS. barre in mind I only tried flashing JB roms as I want sense 5 so I don't know if a custom ics rom would work on my device as I havent tried it yet but I know for a full fact that none of the jb roms work on my device.
For those who are wondering here, I uploaded some pictures of my device just check the attachments. It has all the information you may want to know about my device (HTC One X PROTOTYPE).
I really hope someone can help me update to jelly bean and get sense 5 as I am frustrated from failing and being stuck in bootloops
If you read all of this I honestly appreciate it and I Thank you for it, I hope you can help me!

Thank you for your input, but I already done that which resulted no success for me. The only way for me to overcome these black screens was by flashing:

This makes my device fully functional again but it just leaves me locked on ICS because when do the OTA updates, Flash JB ruu's or even flash custom JB roms I just get stuck on bootloops. I don't seem to get one JB version of android working on my device. Thats why I'm here seeking for help from geniuses like yourself. At the moment my device is back on android 4.0.4 but thats about it. It works perfectly fine on this version but I just can't update no matter what way I try I end up in a bootloop

I flashed the asian ruu first because my CID used to be HTC__621 which requires TW ruu's (I tried the JB one) also on the back of my device it says made in Taiwan. But after flashing the rom it didn't work and put me in a bootloop so I changed my CID to 11111111 and flashed the European ruu ( I tried the JB one) which also didn't work and ended up putting me in a bootloop. It was my friends father who then changed my CID to HTC__001 and flashed the European ICS ruu which worked flawlessly. Do think I should flash the ruu you recommended? because its a ICS ruu and I'm trying to get to JB. Anyway I really thank you for trying to help me, you are the only one who replied to me

Actually @Thant replied also, try what he suggests at the bottom of his post to update your hboot, it's a different one to the one you tried, then try a higher ruu

I am wondering why everyone, OP and those attempting to assist, are assuming that what is apparently a prototype model of the One X would even be compatible with the updates.
If it is a prototype, regardless of how it identifies itself, it may have differences that simply prevent ANY of these software versions from operating.
I think that is one possibility the OP may have to be prepared for.

Maybe you are right he must to prepear and know the chance to broke his OneX is big because is prototype.

That had crossed my mind actually, but he is receiving ota notifications and the results he posted from "getvar all" indicate everything is as it should be, same model number even.
I have come across an early prototype before and the only 2 differences were the casing and slightly larger headphone jack socket. AFAIK the hardware was the same. Unfortunately, the one I saw wasn't working so I don't know what version of android it had

No more RUU only stock rom or nandroid. You never find that RUU because HTC never release this RUU.

[Q] Will OTA updates work after flashing back and forth?

Hi all,
so I got my M8 like three weeks ago and made the ultimate mistake of not backing up MY factory ROM before flashing stuff. I went ahead and, following a guide from 'teh internets', turned my phone into a Google Play Edition after a successful S-Off with SunShine. About a week later, I started missing some Sense features and tried to revert back to stock which proved difficult at first due to partition size issues. Finally, I was successfully following a mixture of several guides in this very forum, flashing different combinations and versions of stock ROMs, firmwares and recoveries. I'm on Sense again. Last thing I can't get rid of is a message in HTC Tell that's talking about a testing device and how I could not turn off HTC Tell for that reason.
Long story short, I do now have a phone that reads:
Code:
*** Software status: Official ***
*** UNLOCKED ***
M8_UL PVT SHIP S-OFF
CID-HTC__102
HBOOT-3.19.0.0000
RADIO-XXX
OpenDSP-XXX
OS-3.28.401.7
eMMC-boot 2048MB
Oct 10 2014,00:20:35.0
Unfortunately, I do not exactly remember which Recovery I flashed last. I'm pretty sure it was one from the Stock Backup & OTA Collection thread. If I go into recovery, I get a red triangle and nothing happens.
Now for my question, I want some features of Lollipop really bad and I know HTC is going to come out with their Lollipop-Sense in about two weeks. I would gladly wait and go for it instead of starting over and turn my phone into a GPE again. Question is, will I get the Sense OTA or is there anything that will keep me from it?
Thanks a lot for reading and any information I got (and hopefully will get in the future) from the folks on this awesome forum!

If you are on the appropriate stock ROM for your CID, and corresponding stock recovery, you will get the OTA.

Red triangle is stock recovery. However, its not clear whether its the right stock recovery. You need to be on the stock ROM for your CID, and the recovery needs to be the one that matches that software number. Just find the stock ROM (and corresponding recovery) for your CID on the following thread.
http://forum.xda-developers.com/showthread.php?t=2701376
There is no harm in restoring the correct stock ROM and recovery over whatever you have now (whether the current state is correct for your CID or not). But being on the correct stock ROM and recovery will put you in the right place for OTA.

Thanks for the explanation.
So it is safe to assume that if I flash TWRP now and restore the 3.28.401.6 nandroid and recovery from this thread, I should A) get the OTA from .6 to .9 and later on B) the Sense-Lollipop OTA?
Sorry for the redundancy of my question but without a speedy internet connection, downloading ROMs is a time-consuming project, so I want to get it right the first time now.

If you restore to .6, it won't install the .6 OTA since its already on that version. But yes, it should install any "more up-to-date" OTAs (and then any future OTAs as they are released) in sequence once you return to stock and check for updates.

Thanks again. I will report back after flashing.

Well, it worked - I think. However, a little more research showed that the red text in HTC Tell is present because I unlocked my phone, particularly the bootloader, via HTCDev. I will consider to revert that change in the future.
I restored (via TWRP) the stock 3.28.401.6 and flashed the corresponding stock recovery. Unfortunately, no update is to be found yet (according to the OTA collection, there should be an update from .6 to .9 which I hoped to get automagically or on manual query in phone settings).
For the time being, I can download the OTA myself from the awesome collection and then update manually through stock recovery, I suppose.

The device will come up as a "test device" since its s-off.

I'm not that familiar with the WWE updates, as its not my version. So I don't know of the .7 and .9 updates deployed to all folks in all regions that have the WWE version, etc. You might check with folks that know more about the WWE updates.
