At&t 2.23.502.3 - 4.4.3 Bootable RUU - No PC required - Mac friendly

All this is null n void in order to run any Lollipop roms. You will not be able to run anything higher than what your current build(4.4.2,4.4.3) do not know what build number is for that specific ROM. Without s-off you cannot update firmware to newer.

Hi, the steps in the first thread are very detailed. However, I'm not certain how many apply to my use case which is keeping me from proceeding further. I'm currently running Liquid Smooth ROM on an ATT HTC One M8 S-ON that is rooted with the bootloader unlocked and I'm using TWRP for recovery. My ONLY goal is to get the bootloader updated so I can run the latest Lollipop ROMS.

So if I'm rooted with S-ON already with a custom ROM....what are the steps needed to flash this and get my bootloader updated?

So now that Firewater doesn't work what do you do to get S-OFF? Sunshine's checker said my ROM must be "close to stock" and my phone failed the test.

Youd have to pay for it@sunshine to unlock your bootloader. And flash back to a stock rom Im guessing. Ive never used sunshine but have seen posts about being as close to stock as possible.

Thanks again for the help. Assuming I can get Sunshine to work, what's the remaining process like? I'm familiar with using TWRP and flashing ROMS but I've never updated the bootloader ever.

Not very complicated...once s-off you can just change cid to BS_US001 and run the 3.28.1540.5 ruu and itll update everything to unbloated 4.4.4

Decided to give this a run today since I have been waiting for the 4.4.4 update and had the itch to flash something. Followed instructions and had no issues at all to get it running. Phone seems to work great but probably mostly due to factory resetting after the RUU installed. Thanks for posting the file and instructions, it was the first run at any flashing on this phone I have done since I got it.

RUU returns Update Size error when flashing?

Tried this today to get back to stock to take the 4.4.4 OTA.
I keep getting an error regarding the update size or something.
Won't finish flashing. It replaced recovery though, looks like it wipes system too.
Firmware isn't updated, system wiped.

I relocked bootloader, I'm S-ON. I've used this before successfully, but I've been using a GPe-based ROM rather than Sense. I didn't think it could repartition or anything without S-OFF, so I don't know if it is that.

I downloaded a Sense-based rom, reunlocked bootloader, flashed recovery, flashed Sense rom, relocked bootloader and attempted the RUU again.
Same error.

Thoughts?

How do I lock my bootloader on my M8 ATT 4.4.3 Insert Rom before flashing this RUU then OTA to Stock 4.4.4?
I've been searching all day for HTC M8 no luck.

Via fastboot. Command is "fastboot OEM lock"

Stock Recovery?

My M8 is 4.4.3, with S-On and TWRP. My question is: can I run this with a custom recovery? My problem is since my phone's software version is 2.23.502.3, I can't find a recovery img with that same version for me to flash. Would this give me a stock recovery?

S-off

Can someone direct me to @sunshine so I can gain s-off?

Thanks, as soon as I posted that I realized how lazy I was.

keeps on saying "device halted due to large image update fail" its on external sd not unzipped and i verified md5

Were you ever able to get this sorted out? I'm having the same issue, although I know that using the RUU like this work because I've done it with the 1.58.502 one. I got that error and paniced, tried to go back to the 1.58.502 and I'm getting the same error... oops something seems wrong here lol

I would highly recommend using a official ruu from HTC. http://www.htc.com/us/support/rom-downloads.html I do not remember how I fixed it but a ruu from the computer should work

Hmm... alright I guess I'll have to do it from a PC then... I'll give it a shot, thanks for the feedback!

Quick question... do you know if you have to be S-ON to do this? Currently S-OFF and Unlocked and it seems to be taking way too long to complete the initial step of "sending" the update to the phone... sorry to pester ya

How long is it taking? Also as long as you're s-off you won't have to relock your bootloader or get s-on. If it hasn't gone past the initial sending update and you've waited like 30 min then try unplugging your phone and rebooting your computer. Your phone will stay in ruu mode and just plug her back in and restart the ruu

Well, I figured out the problem... it was HTC sync manager messing with the phone while it was trying to install. I have a new problem though, it gives me the same error as the bootable RUU. Back to square 1 i suppose...
