For some reason I could not update to Jelly bean, took the ota with the htc root method s-on it wouldnt even install it through teamwin immediatly said failed ! So I tried both odexed and deodexed still the same outcome failed! so I decieded to unroot and go back to stock through SU. I hit fully unroot and went on to the next step of ruu from my laptop of what i thought was the correct ruu based on the version # but a error came up saying 155 something about needing the proper version im kinda at a loss at the moment , at least if I can get the phone back to stock wost case I can take it in for warranty and get another phone to start over with . thanks in advance for any assistace .
 
Did you make a nandroid backup before running the ruu or taking the ota?
Hold down power button until turned off press vol dn+ press and release power to goto bootloader, select recovery and try a restore of last backup
 
First thing I learned about root was to ALWAYS make a nandroid before making any changes, second was to never accept ota
Can you get to the bootloader through the power + vol dn method? If so you might also try a factory reset

yea I can get to the boot loader no prob and into teamwin contol page , tried full wipe already and still nothing different.
 
Did you try a factory reset from the bootloader? Was usb debugging turned on under developer options? When you get to the bootloader, what do the firsy few lines say? Did theota update your hboot?
The more information you give us, the more likely someone here can get ya back up and running quickly :)
 
Yes usb deb was on , thankfully the phone still boots and runs flawless right now just cant update or flash back to stock , Ill have to get you the hboot #'s on the top of the page ina little bit
 
http://androidforums.com/showthread.php?p=5318747 I believe that's the link for the stock rooted Jellybean rom over at XDA, you should be able to flash that via teamwin, just as you would flash anything else, there's a link on xda for the kernel as well. There are two jellybean roms available right now, one is viperboy's, the other is xhausx's. I believe haus's rom, has the kernel baked in, so no need to fastboot flash the kernel separately :D:D
I would probably recommend you s-off though, as it will help prevent a few issues and make flashing roms much simpler :cool:

Im s-on so Im not sure if that is posing a prob . everytime i try to flash from teamwin it just says failed ! in red letters.
 
On your bootloader screen, what do the first few lines say? Is it showing locked? It sounds like you've lost root privileges.
When you goto teamwin, have you tried to look for a backup to restore? That's probably going to be your best option if so.
Really need to know if it updated your hboot version... What method did you use to get root, and if you've still go SU installed, try pulling it up to see if you still have root :confused:
 
Finally, the real pro's! I've been trying to help this fellow get going again, but I was quickly running out of ideas, as you might have noticed lol. :eek:
 
Downgrade your TWRP. I got this same error many times in a row. Checked MD5, evening was fine there. Then I read the newest TWRP has issues flashing some files. I downgraded TWRP and flashed just fine with no issue.

huh i just upgraded twrp and never had any issues flashing roms (its been 3 roms since the upgrade).........interesting might need to look into that.


and to the op. i would just the stock rooted rom that nobegging linked you to, rather then accept the ota.

just make sure to do a nandroid backup, wipe cache, dalvik cache, factory reset, and system and then flash the rom.

If you're constantly getting ERROR 155 when trying to flash an RUU even though you've already returned your phone to stock, you also need to RELOCK the bootloader!

I'm writing this because for some reason just getting the phone back to stock (i.e. restore image of stock ROM through custom recovery then flash stock recovery) didn't work for me. It only worked after I RELOCKED the bootloader.


Step 0. Restore your phone to stock FIRST, i.e. restore stock ROM from image using custom recovery then flash stock recovery.

Step 1. Restart your phone into bootloader either by hard-off (i.e. keep power button pressed for min. 10 sec) then volume up + power button or by adb at the command prompt:
Code: 
C:\> adb reboot-bootloader
Step 2. Type this command at the command prompt:
Code: 
C:\> fastboot oem lock
Don't worry if it says FAILED anywhere in the output, it should all be fine regardless. The phone should reboot automatically into bootloader and should say RELOCKED.

Now you can flash any RUU (EDIT: only if compatible with your CID) and you can also check for and install OTA updates. Once you've done this, your HBOOT and RADIO should be updated to the latest version so you can UNLOCK again using the HTCDev method and then flash whatever you want to flash.


Hope this helps you guys!


P.S. I think it's worth also trying this for other ERROR codes... you never know, it may help.

Thank everyone for your help , the problem is fixed the reason for going back to stock was to start from scratch, I just wanted Jelly Bean , however i tried what nobegging said and went back to a backup from two months ago, after that i then downloaded the deodexed and that said failed ! so I figured i would try the odexed and it worked ! I still dont know why the ruu never worked luckily I didnt have to. But again thank you all for your input .

huh that is weird that the deodexed did not work for you(could have been a bad download). well i'm glad that you were able to get the odexed version to work instead.

just remember that going forward it will be easier to just wait for the devs to cook up the ota into a rom and then just flash it, rather then accepting an ota.

and thanx for reporting back with what worked for you. i love it when member comes back and post their updates and what worked for them so that other members can be helped by your response.........so thanx
 
Quick noob question, just trying to be careful. I'm running CM10, s-on, hboot 1.19. To flash to Haus' rom (MeanRom), all i would need to do is flash it like a normal rom from twrp and let it go to work with the kernel?

welcome to the forums!!!!!!!!
i can't remember if the mean rom has the kernel installer. you will need to look at the op and see if it has it. if not then you will need to fastboot command the kernel as well, since you are coming from an aosp rom.
 
Thanks for the welcome and response! I lurked around on xda for awhile and remembered that I had an account here. They're not as noob friendly haha
