[Q] HELP!!! Rom Update Utility Error 155 - AT&T HTC One (M7)

Hello everyone,
I have a SIM unlocked AT&T HTC One (M7) that I am using on T-Mobile.
I am not rooted (I do not wish to be rooted at this time), and I have managed to get up to version 4.3 by use of the HTC RUU, but when I try to get to android version 4.4, the RUU shows error 155. How would I fix this?
Help Please

Thank you for replying. I have tried that one already, as well as the one from HTC1Guru. Both of them read the build number as 4.20.502.1 instead of 4.18.502.7 . I believe the error keeps happening because the build number does not match and pretty much my laptop won't allow it to upgrade as long as the build numbers don't match. I will try it again though.
Thanks,

P.S. has this happened with anyone else?
Update: I have re-tried the update now. At 5% and checking header. I will give it over night to update.

clsA, is this an official RUU from HTC? Every time I try do it, it hangs at 5% (checking header...). I just want to make sure there is no virus/malware here. and androidruu.com is blocked at the location I am at. It says that there was malware found on AndroidRUU. Can you confirm any of this?
-Malware on AndroidRUU and
-official RUU from HTC

Malware no I've never seen any infections RUU

So, are the RUU files are official from HTC? Also HTC1GURU was not blocked at the location I was at. I got the RUU from there. I am guessing both of the RUU files from both websites are the same?

Yeah their the same file
And no their not on the HTC site
I'm not really sure where they originated from

Oh ok... Well, now I have a new error when I try from a last resort computer. When I try and run the RUU an error box comes up that says "htc_fastboot.exe has stopped" and then everything crashes. This is an error I have not had anywhere else. Any suggestions?

I'm pretty sure the 4.18.502.7 RUU on androidRUU was leaked from some member of the HTC elevate program, that's why it changes the build version to 4.20.502.1, so that it's clear its not the GA release (and possibly to prevent downgrading once its installed.) Also, several reports of that RUU failing to install, possibly it has different signature-- I don't really know.

Are you recommending that people not install that RUU and just wait for HTC to release it?

Just sharing my observations. If you're trying to stay 100% stock and are currently on 3.17.502.3 then download the 4.18.502.7 OTA and flash it in stock recovery.
@clsA posted it here.

Thanks for the info ... I know I downloaded the RUU when it first come out and had @nkk71 decrypt the rom zip for me ... he mentioned that it had errors during the decrypting but nothing specific, just that he fixed it. Flashing the rom.zip alone fails on all attempts. I was s-off when i flashed the RUU.exe so i don't really know if it's a signature problem or not. The Decrypted version i uploaded worked fine on my 2nd One (s-off of coarse). But I have had reports of it not flashing also ...so I'm really not sure what to think.

I have tried going into the current recovery already. The OTA is on the root of internal storage. I went into the recovery and went install from phone storage, and it had an error and just restarted my One. If you have a few minutes. I will do it again and say what the error was.

I've decrypted the RUUs as well and the format has changed in KK RUUs (due to the size) so now the encrypted rom.zip contains 5 zip files: firmware.zip, system1.zip, system2.zip, system3.zip, and userdata.zip. That's why we see messages like "checking 1/5" when it's flashing, it's verifying each of the 5 zips.
I haven't attempted to flash that RUU (or any RUU for that matter), been on CM builds for the last year.

Give it a try, let's see what happens. There's also a means to flash the OTA in TWRP that worked for at least a couple of people: here

Other's have reported that, it's seems to be an issue with the update script checking the CID.
Does your fastboot screen show CID CWS__001 and OS 3.17.502.3 ?

I don't remember changing the CID, unless unlocking it did that. That won't wipe my phone if I do that, right?
