[Q[ Questions on RUU

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

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?

[Q] CID, firmware, jellybean etc...

Hi all,
I have installed RD-MIUI Jelly Bean 4.1.2 (http://miuiandroid.com/community/th...-bean-4-1-2-2-11-16-en-cm10-16-11-2012.17645/) on my HOX and it is working fine (a few bugs, but they are known).
My question is: why could I install it in the first place??? I didn't touch the hboot, but for many roms it looks like I need to upgrade it.
Why, for example; I am not supposed to be able to install Android Revolution HD 15?
See:

My CID is HTCCN701 - so no firmware for it.
Can someone can explain to me how:
cid
hboot

are related? And, although I understand the word and the wiki description, maybe a bit of explanation of what are concretely these entities, like which file is responsible for what, how these are layered, etc... I have a programming background, but I am still a bit lost concerning the architecture of android and its devices...
Thanks in advance!

Upgrading the hboot is only required for Sense-based Jelly Bean ROMs. You will not require an upgraded Hboot to use AOSP/AOKP/CM10 based ROMs.
CID - basically just identifies region/carrier of phone
ROM - variations of the android OS, usually comes with custom software/tweaks etc.
Hboot - not too sure, but different versions have an effect on wifi, reception.
kernel - basically a component that serves as the bridge between software and hardware and allows them to communicate between each other.

Just see the hboot as the BIOS on a pc

Guys, thanks for the clarification!
Another question though... How come I would need to upgrade my hboot (keeping the BIOS analogy) so that Jellybean-based Sense can be ran properly? Is that because Sense has access to low layers? From your explanation, I would have thought the kernel would do that job...
Indeed, if we compare to a PC, I usually don't need to upgrade my BIOS when I want to change my OS... Hence the reason why I am confused

Well the hboot (bootloader) part interacts with the kernel and this will talk with the rom....
Because the kernel and rom are updated with the new JB update, it needed an update from the hboot too so it can interact in correct way. I think this is the easiest way to explain it
hboot - kernel - rom.
PLEASE CORRECT ME IF I'M WRONG

I have been unclear about this as well (great question). This sounds like a good explanation (hey Marcel!). But I'm curious as to why my CID is HTC_203 and I'm on ARHD v15.0 and it says in the OP of that rom that I need to "upgrade my firmware" and when I look on the firmware thread http://forum.xda-developers.com/showthread.php?t=1957376 it says that my CID should have hboot 1.31. So, apparently it's not absolutely necessary to have the latest firmware? My rom seems to be working fine. Also, if I now want to use an ICS rom, will my CID/firmware (hboot) be an issue?
Ugh, can't believe how much more complex this phone is compared to my old Nexus! lol (but it sure is beautiful!)

You have to check the hboot number if its higher as 1.12 then you have the JB hboot update. A JB rom will run on a lower hboot but that is only for the de-sensed roms !
And hboot number for ICS roms is irrelevant :thumbup:

Oh, wow. I see. :good:

Hboot can communicate with the hardware directly and controls all the security of the phone partitions.
Aside from booting the kernel
WiFi and other hardware bugs(dead sensors/sound and touch static electricity) were caused by incompatible hardware code between different hardware versions.
Edit: you only need to upgrade the hboot if you want to install a jb sense rom(stock or custom, restricted by sense+ software)

You mean I can flash a non-sense rom such as CM10 on my phone although I don't have a compatible cid?
From what i've read from the guide threads, you're supposed to have a cid similar to "HTC_001" or something like that to be able to flash a JB rom into the HTC one X. Am I wrong?

Would it be too much asking for the best CM10 rom link? I know they're there, but they're a bunch and I'm not really sure which I should flash.

Depending on which version you can go to, you might have problems. 1.33 and 1.36 should be ok, but with earlier versions you might find bugs.
Also, if you update it, for non Sense ROMs, you'll need a non standard boot.img, and at the moment, most of them don't work with GPS.

i would personally go for the official CM10(4.1.2) nightlies at cyanogenmod.com because i don't mind flashing a daily new update(doesn't require wipe data). I had defy with CM10 and as fast as I noticed any bug it was fixed in the next day's release. But I don't recommend this if you are looking for a permanent rom.

I would like to add that the chance of finding a security hole in newer hboots is smaller , and I bet that no one would want to miss applying an S-OFF exploit.

I was getting reboot after reboot so I tried restoring my stock rom from de clockwork mode. Now all I get is the HTC One X boot logo.
I forgot to move the stock boot.img from my phone to the pc and now I don't know how to push it from the phone to the pc without system.
Any ideas?
edit: alright, I really need some help right now. I'm freaking out. All I need is to send the stock boot.img I have on my backup to my pc so i can flash it via fastboot usb.

I think the problem may be usb debugging. Idk if i have it enabled.

[Q] How to update from a very old (v3) rom to a new Jellybean (v12) rom

I've been away from the ROM scene for quite some time now, but some of the new Jellybean features (coupled with constant pestering via an OTA update) have persuaded me it's time to upgrade.
I'm currently running Football's maXimus Rom v3.1, which is an old ICS rom. I'd like to upgrade to his latest version, but i'm struggling to remember/work out how!
I'm currently running hboot v0.95, and i'm pretty sure this needs to be updated to a version 1.3x, which i've no idea how to achieve! In addition, i've seen a video Football posted in his thread which refers to an updater_script.zip file, which I can't find either!
So far i've re-installed the android SDK, downloaded the latest version of the ROM and popped into the root directory of my OneX, and downloaded the fastboot kit for v12. What else do I need to do before getting some Jellybeen goodness?

In this Thread you will find anything you need related to hboot.
After this just flash rom and kernel as usually

Brilliant, that tool looks absolutely perfect!
One final (hopefully!) question - i've set up the JBFW tool and placed the relevant files in the folder, but my CID comes up as 1111111 - does this mean I can't upgrade? And if so, is there anything I can do to change this?
Also, in the thread you linked to it mentions that 'everythings included except the RUU' - do I need to source an RUU? (and find out what one is!)
Thanks again!

It means you have super cid.
You can flash any rom you want without any cid restrictions. Still i would like you to get a 2nd opinion on what way to proceed.

Is your device s-off ?
You can proceed with flashing anyway

[Q] What's the use in updating your hboot version?

Hello everybody,
as the title suggests: (Why) should I update my hboot?
Yes, I've searched, yes I've read. I'm sure I could find the concise answer if I invested several hours of reading various highly informative threads, but maybe somebody can put it down in a few, easy to understand sentences, or point me to a post / wiki entry where it's explained concisely?
My situation: I have the HTC One X (Tegra 3 version), rooted, S-ON, with the 0.43 hboot at the moment. I have installed several ICS sense roms in the past, and am currently running JB (4.1) AOSP (/CM/PA/...) roms. This all works nicely, but I really don't understand all the talk about different hboot versions, needed RUUs, etc.
So I have several more detailed questions:
If I got it right, I need a newer hboot version to run Sense JB Roms - correct?
To upgrade to a newer hboot version, I need to download the correct RUU and install this, correct?
How do I find the "correct" RUU? And am I right that the RUU is an offical exe file, installing the Stock Rom on an unlocked phone only (meaning I have to relock first)?
Is it correct that hboot version more current than my original, never updated one will cause problems (GPS, direct wifi, volume, bt, ...') with basically ALL Non-Sense roms?
Is it correct that once upgraded, I have no option whatsoever to downgrade?
What is the interaction between the hboot and the installed kernel - do some kernels work better with certain hboot versions?
Sorry for the flood of questions. As you can see, I really tried to find the answers. In some cases I'm rather sure of what I think, but some questions leave me baffled. At the moment it seems to me that I have to decide between either a Non-Sense JB, or a Sense JB, but I cannot switch between them (and retain all functionality of my phone).
Thanks in advance,
Thor

if you upgrade it, you will be able to flash jb based roms, as you already know, there are jb roms out, which boots on any version of hboot, some dont, thats why you need to upgrade, for example, im running the blade rom v3.0.0 which its great, but i couldnt flash if i didnt upgrade the hboot.

[*]If I got it right, I need a newer hboot version to run Sense JB Roms - correct?
Yes perfectly right.
[*]To upgrade to a newer hboot version, I need to download the correct RUU and install this, correct?
Yes, that is ONE OF THE methods to do it. Another method is, you can use this tool. (It doesn't require you to relock you phone)
[*]How do I find the "correct" RUU? And am I right that the RUU is an offical exe file, installing the Stock Rom on an unlocked phone only (meaning I have to relock first)?
First, head over here and check whether your CID has received the JB update (upgraded hboot). If it hasnt then you will have to wait.
If it has then you can search for your RUU.

Nope, it will ONLY cause a problem with the non-sense ROMS that were built on the older base , i.e. the ones running android 4.1.2 , newer ROMS like android 4.2.1 builds will work perfect, and that too only gps is a problem. Also, most of the devs have found the patch to fix this problem.
[*]Is it correct that once upgraded, I have no option whatsoever to downgrade?
yes, that is correct.
[*]What is the interaction between the hboot and the installed kernel - do some kernels work better with certain hboot versions?
There is no such relation. The only relation is that the kernels wont work only, i.e. the kernels built on the older source code wont work at all on the upgraded hboot. And there are no custom JB kernels as of yet as HTC hasnt released the source code yet.
Hope this helped.

Thanks for this VERY helpful reply! What I don't understand about the two points I've quoted: You say that most of the devs have found fixes so that 4.2.1 roms run perfectly, but at the same time that there are no custom JB kernels. I thought the gps problem had to be fixed in the kernel? But that's probably just my misassumption.
Even if my phone hadn't hadn't just badly broken, I'd stick to the old hboot for a while longer then. I don't want to switch to JB 4.2.1 yet, as there seems no way to get pdroid running on that.
Thanks for taking the time to answer (this goes to all of you who replied)!

What they mean is that they have patched the ramdisk in the 4.2 ROMs to work with the older 4.1 kernel's that we do have the sources for

[Q] Updating HBOOT

So I've recently decided to get the newer version of the Cyanogenmod for my One X (Android 4.2). However, after finding out that I get an error each time I try to install the new version, I did some searching and realized that I needed the newer version of HBOOT. I now know how, but I get the warning that after doing so, I will be unable to install a non-sense ROM. Is that so, and if true, is there a way around it apart from installing an earlier version of Cyanogenmod? Thank you

Not true afaik. Aosp roms runs fine on the higher hboots (JB). In fact there are JB non sense roms that need a JB hboot to run ! Do you have some links where that is written ?

It confirms that you need a JB hboot of 1.28 at least....or higher, so it wont run on 1.12. You need to update the hboot in order to run it......so the question about not being able to run a Aosp rom on the higher hboots is not true ! You need one to run them

Thanks - just wanted to check to make sure I don't do anything wrong by upgrading the HBOOT.

Nope ....go right ahaed and flash CM10.1 after
