Hey Guys,
I just had some questions regarding RUU's and sort of trying to understand them.
Do RUU's update everything that normal custom ROM's cannot, i.e. like the OTA's? So updating drivers and hboot etc?
Main reason is that if it does update everything then on the next big update I would probably want to do an RUU install even if it means loosing all data.
With regards to the RUU do I need all three of the following:
- Stock ROM
- Stock Recovery
- Locked bootloader
Or do I need JUST a locked bootloader?
Thanks
Yes you will get updates if you flash a ruu and ruu 's are pure stock ruu's are used when we need to put the stock Rom back on our device when we need to send it in for repair's and also when we prefer the stock Rom over a custom Rom I my self prefer custom Rom over a stock Rom and sometimes when a custom Rom isnt performing the way it should some people will simply go back to stock by flashing a ruu

Thanks, my main reason is actually not to say on an RUU but I was hoping to install an RUU, get all the updates to my firmware and drivers, then unlock bootloader again and install a custom ROM.
They should be updated by a custom rom. Only thing that isnt touched is the HBOOT i think. But reflash stock recovery relock the bootloader then run the ruu.
Flashing an RUU first if available is the way to go personally

I readin a lot on here and I read somewhere updateing with ruu updates hboot and hboot is some sort of security so updateing it could make getting s-off harder
Sent from my HTC One X using xda premium
Updating the HBoot means adding more layers of security, which imo is not something we enjoy here on XDA
Personally, I prefer going with a custom ROM that is almost like stock (preferably ARHD) which with every update brings the improvements brought to us by HTC and even more.
Also with ARHD for example, upgrading from one version to a newer one rarely requires you to wipe all your data which is very annoying imo.
I've been on Custom roms since I had my phone so I had missed the OTA update for 1.xxx.11 and the 2.xx versions, now with the a big 3.xx version on the horizon, my main concern is if my Custom ROM's are not updating some critical firmware drivers and such that would have benefitted my phone.
Tbh it's still not clear to me what Custom ROM's cannot update, at first I thought it was just the HBOOT but then I read on a recent thread that apparently things like GPU drivers and other essential hardware firmware drivers may not get updated either which sounds like a big deal. Hence I was thinking with the release of 3.xx I should do an RUU install just to be sure and then go ahead to a Custom ROM.
I understand that having my HBOOT updated could mean S-OFF is harder but the way things are, it doesn't look like were any close to getting it either, who knows maybe even a future HBOOT update might have an easier S-OFF is HTC decide to relax it a bit from consumer pressure?
When developers get their hands on new RUUs they base their custom Roms on them, and therefore you will get the new updates in terms of drivers and other software related things.
Also, kernels bring new improvements as they are updated, and developers also build their ROMs on these kernels. However, you can flash custom kernels separately if you find one that has additional "improvements" you like.
In short, custom ROMs that are maintained/updated regularly (ARHD is one of the best imo) is all you need to stay up to date with all the new improvements.
The only reason I ever download any RUU is in case something went wrong with my phone, and I wanted to temporarily return to stock.
Ah right, I was thinking more of the S-ON security restriction not letting custom ROM's fully update everything except radio, kernel and ROM but RUU's are given the full access to update everything?

I don't think there is consensus on what can be updated and what cannot.
Here's my take: an OTA has access to everything, as does an RUU, but the point is that they flash signed images, and the phone will allow signed images to be flashed (subject to matching CID, etc.).
It's possible to flash kernel with the boot.img, and also possible to flash kernel modules, which means that drivers can be updated.
It's possible to flash "radios" (often as part of the ROM), and there is an app to get updated RILs, so it would seem that the RIL has not been confused with the radio. However, since the bootloader appears to get the radio version from a text file, rather than the radio, there's some doubt as to whether the radio is really updated (since the bootloader disagrees).
Obviously we can unlock and gain access to flashing unsigned recovery, boot (kernel/ramdisk) and ROM images.
Outside of this, it's not impossible that there are areas of the phone that still require flashing of signed images, such as for firmware updates of other bits of hardware not previously mentioned (speculatively: lower level bits of "radio", cpu microcode, gpu firmware, etc.), which may or may not be flashable with an RUU (or maybe even an OTA). However, there is nothing in an RUU that cannot be done with tools we already have, so if there was a "fastboot flash cpu_microcode" option, somebody would have found it. I haven't looked at full list of fastboot commands, but I don't recall coming across anything like that.

There are some parts of the firmware/drivers that custom ROMs cannot change so flashing an RUU first does have it's benefits to get a true experience of a custom ROM

Do you know what, specifically?
I don't, no, it's just a personal preference I suppose. I updated to the 2.17 RUU (UK unbranded) and then went onto a custom ROM based on the same RUU so I know everything is compatible. Whether it has any real affect I don't know but seeing as Mike used to have 'firmware' packages for other HTC handsets it would lead me to believe he would with the One X if we had S-OFF

...there are a lot of masked partitions, eh? Who knows.
A lot of the partitions were listed in the S-OFF thread but as to what they actually contain/do is open to discussion - it could be a custom ROM it's own is enough but without S-OFF we'll never really know

Have you read anywhere of any improvements offered exclusively by RUUs or you're simply speculating?
I know some partitions (that appeared to be in the HOX) are not accessible by Custom Roms, but has anyone ever claimed to have experienced an improvement in any way by flashing an RUU that people flashing custom Roms haven't?

Hey guys, i just flashed my M8 using vomer's Guide, everything went great except for the S-OFF part, firewater didn't work on my variant (T-Mobile Version), i was just wondering if it will affect my phone in any way while trying to flash a custom rom, right now im looking at flashing Skydragon's GPE or Sense version
You can still flash roms with s on, just not do the GPe conversations
The ones known as RUU right?
If you flash a Sense 2.22 based custom ROM, its recommended that you flash the updated firmware package (S-off required) or else wait until the 2.22 based OTA rolls out for your version (which will include "official" firmware).
If the updated firmware is not installed, 2.22 based ROMs will usually cause some major bugs, like excessive long boot time, broken WiFi and Bluetooth, etc.
S-off is usually not "required" to flash a ROM per se. This is an exception where the older firmware modules (not included in the ROM itself) are not playing well with the newer based ROMs.

You can always try it and see. I'm not sure if 100% of folks will have this issue (if you do not update firmware), but others have said you will "probably" have some major bugs.
On the other hand, if you are s-off and already have fastboot setup on your computer, the process to update firmware takes maybe 5 or 10 minutes.

i just found out that they have a separate version for the T-Mobile variant, maybe thats what i will install, on a side note, do you think it would be a good idea to take the plunge and pay for the sunshine method to gain S-OFF?

Its very much a personal choice. It you want the freedom to be able to flash firmware packages, radios, etc. at will; and $25 is something that you can afford to give away, then I'd say its recommended.
I had the luxury of being able to s-off earlier on for free, with firewater.
Well, I'm s-on and I've already had gpe edition installed.

If the 2.22 firmware is all you want s-off for, probably not a bad idea to just wait for the T-Mobile OTA rollout. Then you can just install the new firmware "official" OTA way. Once the firmware is updated, you should be able to flash whatever you want with S-on.

That's all i want it for, maybe it is a good idea to wait for T-Mobile to roll out the update, anyway, i flashed the Skydragon GPE ROM yesterday and everything is going fine, i have yet to test battery life, since today it's my first day of use, but everything seems to be running fine, thank you for all your help.
Hello all, please be gentle, I'm only back to the Android scene after a sebactical using iPhone. I have a UK O2 HTC One M8, CID is O2___001, HTCdev unlocked with S-On. I have installed a GPE rom (SkyDragon v3.0.1), brilliant rom, but wanted to revert back to stock sense. All the guides I have read state that in order to revert back to a sense rom I need to have S-Off, however the firewater method isn't working (having tried a number of different kernels), nor does the Sunshine method. I have tried to find an O2 RUU for the same CID with no avail, so am really hoping someone can help. Ultimately I am wanting to convert my phone to a GPE with OTA, but need to be S-Off to try this, hoping if I can get back to a Sense rom I will be able to achieve this. Hope this all makes sense. I have spend a good part of the morning searching through these forums, google, and even youtube looking for help, but am having no luck.
I have also tried to flash Android Revolution HD 21.0, it appears to install correctly, buy when it reboots it won't boot past the white HTC screen, all other guides state that I need to update the firmware, but need S-Off in order to to this.
Im starting to get confused so would really appreciate nay help anyone can give me.
Cheers in advance for anyone kind enough to reply.

You only need to "convert" back (s-off required) if you did the full conversion to GPE in the first place. That also requires s-off, and you mentioned you only flashed a GPE ROM (not full conversion) so it doesn't apply to you.
You can just flash a Sense ROM. But as you mentioned, you will encounter the firmware issue on newer Sense ROM. But there are still a variety of Sense ROMs still based on older versions (to get back to Sense).
However, you will want the stock ROM and stock recovery for the best chance of sunshine to work, and it doesn't look like those are posted on the stock nandroid collection for your CID: http://forum.xda-developers.com/showthread.php?t=2701376
RUUs are only available for US carriers, AFAIK. So that is why you can't find one for O2.
Thank you, found an old sense rom that matched my firmware, and sunshine worked, not have S-Off, thank you again.
So I've been running GPE 4.4.4 ROM for close or over 5 months, and tried flashing the new sinless ROM, only to discover I seem to not be able to without updating firmware (?)
Anyways, I'll just keep this short. I'm running TWRP v2.7.0.2, S-ON T-mobile HTC one m8 and just want something new. Not super picky, suggestions welcome, but mostly need to know how to get caught up!
Thanks in advance, let me know if I forgot to include any info.

My advice would be to get S-OFF using firewater method. You can search it on youtube in less than 1 min. Once you get S-OFF I recommend changing your phoneID to superCID. Also you should flash the newest version of TWRP to not run into any trouble. Once you gain S-OFF I recommend flashing the latest sense firmware http://renovate-themes.de/index.php?s=firmwarewhich seem to be much more stable+performance oriented.
Right now at this moment we do not have an official lollipop release. There should be a GPE 5.0 coming soon to the m8/m7. You should definitely try out CM roms and AICP roms if you like tinkering around with your phone. CM/AICP should be out with android 5.0 very soon also.
@watchmuu
Now you can try like everyone else for days trying to get "firewater" to work or bite down and spend $25 on "Sunshine"

You need to update your firmware, as discussed on many different threads.
And by updating your firmware, he means the "baseband", not the rom itself. You will most likely need to S-Off.

Firmware is not the ROM itself, that is true (and a common source of confusion). But it includes a variety of partitions/modules not contained in the ROM, only one of which is the radio baseband:
hboot
radio
WiFi (and its this one that is causing the issue)
Bluetooth
Media
Stock recovery
boot.img
Others
Updating firmware is possible with s-on by returning to stock ROM and stock recovery, and updating via OTA to the current Lollipop software and firmware. After that, the OP can flash custom recovery again, and the custom ROM of choice.
Could you possibly show the right direction in doing that, im having trouble finding stuff for this specific model

Did you try to flash the stock Lollipop ROM for your version (CID)?
What you probably need to do is flash the 2.16.654 stock ROM, corresponding stock recovery, than OTA up to Lollipop to update the firmware. Finding the stock 2.16.654 ROM may be the challenge here.
You didn't happen to make a nandroid (TWRP backup) of your stock ROM before flashing any other ROMs?

With s-off, you can flash a firmware package without having to jump through the hoops of returning to stock and OTA updates.
But if its not the Lollipop firmware for your CID (for instance, you can't find it), you'll need to make sure its one that has a radio baseband that plays well with your local carrier.
The one hitch, is that you may need to restore to stock in order to run sunshine s-off. Sunshine may or may not work with LeeDroid. It might be "stockish" enough for sunshine to work.

I'm not talking about your ROM preference. I'm referring to the fact that stock ROM (and also stock recovery) is the best configuration for sunshine s-off to work. But you are in kind of a Catch-22, in that you are trying to get back to stock. And by the time you return to stock ROM and stock recovery, you are pretty close to just updating the firmware by OTA, anyway (and in that case, s-off isn't needed).
Some folks have had success doing s-off with certain custom Sense ROMs (while other ROMs will interfere with sunshine). I think InsertCoin and Maximus are the ones I've seen mentioned, and LeeDroid might be close enough to stock for sunshine to work, also. Its worth trying, anyway (if s-off is indeed what you want). The sunshine app will tell you whether your phone is compatible or not (and if not, then you can try a different ROM), and you won't be charged any money unless it works.

Any way to s-off besides sunshine? NO.
If you are asking if there is a way to update firmware without paying (therefore with s-on), I've already described that process in Post #6 above. But as I already mentioned there, you might have trouble finding the 2.16.654 stock nandroid. You may need to ask for it to be posted, or look around.

Ah, yes. I don't think it even occurred to me that your version was Sprint, and that it had RUUs. While I'm in the US (AT&T) I'm so used to helping folks outside the US (and most variants outside the US don't have RUUs).
If you used the RUU to update to version 4.25 firmware, that is already up to date, and there won't be an OTA at this time.
