It seems there is a lot of questions regarding the EVO, root and more--so in an effort to clean up redundancy, I'll make an attempt to answer many questions in this thread. I'll touch on a number of important points initially, then you can fire away with questions which I'll (do my best) to answer.
If you have a question, you should read this thread before asking, as it may very well be answered here. If you don't see it, ask away!
Is the EVO GSM-compatible? Can I use it with Verizon?
Short answer: No. The EVO is CDMA-only, and does not contain a SIM card slot. You can try to get Verizon to accept the EVO on their network, but doing so will require you to first convince a representative to do so, which has been virtually unheard of (Sprint and Verizon, despite using the same CDMA technology, maintain HEX ID white lists for phones, and if your phone doesn't match, they can't activate it in their system.)
If you're on Verizon, I'd advise you to consider the Incredible, or wait for the Shadow.
What is 'Root'?
Root access (in linux/unix terms) is the equivalent of being an Administrator in Windows. Without being 'Root', or 'Administrator', what you can and cannot do is severely hampered. You are essentially using a 'Guest' account, with 'Guest' priveledges. This means that whatever HTC/Sprint/Etc. has deemed appropriate for 'Guest' users is all you have access to.
So why do I (or we) want Root access?
Having Root access means we can do whatever we please to our phones. As I said above, this gives us Administrator rights to add, delete, or do as we please to our devices. Without Root, you are forced to do (and use) whatever software Sprint/HTC want you to use.
Can you give us some examples?
Yes. With Root, you can flash a build of Android that someone else has created and/or customized. You can update/reskin your device as you please, add or remove software at your liking, and tether free of Sprint's surcharge. Additionally, without Root, you'll have to wait for Sprint and HTC to release updates for the EVO (which could be months..) with Root, you can load a build as the developers produce it.
Froyo will most certainly arrive (in time), but what about Gingerbread (2.3)? Whatever comes after (2.4)? There is no guarantee that Sprint and HTC will support the EVO that far out. The developers who have this phone, however, most certainly will.
I'm going to have my EVO for at least two years, and I plan on migrating and updating my device to the latest version of Android regardless of what other customers/users who do not have Root access are able to do.
...But there's a risk in getting Root, right?
Yes, there's a risk of bricking your phone, and however minimal that risk is, it needs to be stated. Your best friend is knowledge, so read carefully, read again, and follow directions. You're already here on XDA, you'll be just fine.
I'm concerned that the developer's builds of Android Eclair 2.1 and/or Froyo aren't fully functional, or we won't have the same functionality after Rooting.
Patience. Functionality is dependent on having a Kernel that supports all the technology on the device; an OS to run with that Kernel that supports all of the technology on the device, and the device itself. We have the device and the Kernel, we're just waiting on an official AOSP Froyo release.
If that doesn't make sense, consider this: HTC heavily modified Eclair to support technology like tethering, 4G, front and rear cameras, HDMI, etc. They had to modify it manually because support for it wasn't available in Eclair, but it IS available in Froyo.
In time, everything on the EVO will be fully functional in Froyo.
Where's Froyo?
Google will make Froyo available on AOSP when prepared to do so. Until then, the latest release of Android is Eclair 2.1r1. Again, Eclair doesn't support everything the EVO has to offer, so until Froyo is available, some items may not come to fruition in the developer community (4G access, tethering, etc. as examples.)
Wait a minute, can't I run Froyo from an SDK build?
Yes, you can--but an SDK (Software Development Kit) build is essentially OS files torn from the emulator in the SDK. This may or may not contain all of Froyo's end-result code, and may not be completely indicative of what a final release of Froyo will be like. It IS very useful for testing and tinkering, and isn't necessarily even a bad build to use on a day-to-day basis, as long as you understand it's limitations. When you're reading threads about functionality for a Froyo SDK build for the EVO, now you'll hopefully have a better idea as to why that functionality is limited right now.
I hate Sense UI! What can I do? Can we remove it? Can we replace the modified applications?
You can disable Sense, but you can't remove it (unless you're Root and can replace the OS entirely, that is.) Sense is deeply integrated into the core of Android in the release HTC and Sprint provide, so much so that certain applications (People, Messages, Internet) cannot be "undone" short of (again) replacing the ROM. You can disable the widgets, and replace the launcher (ADW Launcher is a solid alternative), but at the end of the day, Sense is so tightly coupled with the EVO stock ROM that you can't completely remove/replace or restore the original Android system files.
This is another good argument for wanting Root access.

do a search for adb ubuntu
the sdk for ubuntu is at google's android site.
First, thanks for taking the time to post a good compilation for some beginners like myself.
This is my first android phone, however I have been following the progression of the OS for some time.
As you stated above,
"With Root, you can flash a build of Android that someone else has created and/or customized."
I have seen on other forums, such as the hero forums, that there are several different choices for custom roms. I tried to see what the main "features" were but they seemed a little too technical for me at this point.
What are the main differences between different custom roms in terms of how they function or what they do differently, aside from OS versions?
Also, I do see that certain roms indicate they have the Sense UI turned off or tuned down. For someone who has only used stock roms which have sense already on, what does a reduced/disabled version of sense look like?
Thanks again!
I read that the Sprint OTA update that fixes the SD card issue breaks the first exploit for root, but that the Unrevoked exploit can still root even if the OTA exploit has been applied. Since I'm having SD card issues, I wanted to go ahead and accept the OTA update I initially declined. I tried the option to check for a firmware update, and it says there are none for me. I also tried the HTC software update, and it says I was already up to date. Does this mean the update got applied somehow already? Is there a way I can tell? Am I doing the wrong thing to try to force the update? My phone says "Firmware version 2.1-update1". But I'm still having SD card issues.
I'm also wondering if this thing can be unrooted, in case I need Sprint to handle it.
Thanks Shidell...much needed!!!
I am interested in a future update to froyo 2.2 w/ its new features, removing a few stock sprint apks and mainly, replacing the painful htc sense with AOSP. I much prefer the new AOSP launcher and 3d app drawer. UNTIL THEN, i would probably just like to remove some apks and add in some that may not be allowed from sprint (google nav? usb tether? etc) and maybe disable sense (like above).
What do you recommend? Toast Root, unrevoked sticky apk? Should i wait to root altogether?? Do i need to avoid future OTA's etc? or would rooting now be the way to go to protect future root options?? i just don't know what to do!
Thanks for your thread! Can't wait to utilize the evo in all its glory!! My vogue just couldn't cut it anymore.
Can we get this stickied? It's great info to refer to for all people (new or just new to android)

If you want to "unroot":
http://geekfor.me/evo/ruu/evo_ruu_1326511/
This is an exe that just flashes the phone back to the way it was when it was shipped (you'll lose all your data on the device, but your SD card should be untouched).
Also, to check for the update, you want to look under the Menu>Settings>About Phone>Software Info>Software Number
The OTA changed the last digit from a .1 to a .6.
Hope that helps!
sticky???
agreed, sticky please???? that would be great

In regard to rooting and ROM customization, one primary difference (always) is that you have root access, so that's something to keep in mind. From there, the differences usually include what version of Android you're using (Cupcake, Donut, Eclair, Froyo, etc.) and then what software packages are included.
"Sense UI", for example, is HTC's skin for the Android OS. "MotoBlur" is Motorola's skin, and Samsung has their own variant, as do others. This is a lot like customizing Windows; it'd be like changing the background, the system sounds, and the way Windows appear/look. Skinning is akin to theming. Attached is a picture example.
Note that different skins/themes sometimes include more than just visuals; Sense UI, for example, replaces the default MMS and Contacts applications with HTC's variants, as well as replacing the default system keyboard application. How much is customized is up to the manufacturer.

I'd suggest using Toast's method. The process is straightforward, and will allow you to achieve root access. From there, you can flash the ROM of your choice--be it Toast's Fr0y0 build, or an alternative ROM from another member. Toast also links to a Stock-ROM that's been modified for root access. This will give you the same experience as your phone was default, but with root access. This also means that you can uninstall certain applications, like Sprint TV, should you desire to do so.
However, you'll still be stuck using other Sense UI applications, like contacts and MMS, which I don't really care for. It's just life right now.
Froyo should (hypothetically) be made available soon, and then everyone with any iota of knowledge is going to be working frantically to build a full, feature-complete ROM with everything working (and then some), including tethering, HDMI out, full GPS/Wifi/Bluetooth/4G support, etc.
My recommendation? Root now using Toast's method, be wary (and read about) any updates before you perform them, and experiment with a few ROMs before Froyo is made available. Prep yourself now for Froyo and it'll be smooth sailing once it's available.
Nice thread

1. So "toasts link stock rom", is that flipzmode's rom you are referring to? And that will give me the same exact experience as i have now, except for with root so if i want to modify SenseUI or some sprint apks i can? (i don't want anything to be removed or changed already, i just want to protect root for future when froyo comes out for our device with everything working).
2. and what does it mean when toast says: "you will need to wipe data and dalvic cache before flashing this." How do i do this?
Thanks!!
nand unlocking?
What is the significance of the nand unlocking? if we can already root, what extra does this allow us to do?
Hi. I have searched the forum, and checked google for possible answers for about 2 days but haven't come up with something I can use.
I got my HTC Desire a couple of days ago and soon upgraded it to froyo. However being from Denmark i realized that I do not have the option to purchase apps, which leaves me with some demos and apps I would like to buy the full versions off.
I then browsed the topic and saw that my best option was to root my phone and give it a custom rom.
After all methods had failed me I browsed a little more to find out that none of the methods I had used would work on 2.2.
I then found some nice guides about downgrading but all of those said something like: Don't do this if your phone is either *gibberish* or *lots of numbers*.
So basically that leaves me with a bunch of questions:
1. Is there a way to enable the market without rooting/flashing until there is a way to just root 2.2 (this is without buying a foreign sim card)
2. IS there a way to root 2.2 that I simply missed?
3. is there a way to downgrade at which I do not have to fear utter destruction and chaos.
4. Why does google not love me back
I have the same problem
someone? please.
I too could do with a guide on how to downgrade from OTA froyo (hboot 0.92) in order to root and flash a custom rom. Battery life isnt really acceptable in the stock froyo and I could do with sideloading one or two apps from my hero.

Yes, but it's not a one-click-solution. You need to downgrade to hboot 0.80/Android 2.1, then root your phone, then flash any cooked ROM you like.
Read all the details here.

Ok, i had a G1 & i never rooted it, now i have the the Desire & havent bothered rooting it as i think Android seems to be cool from stock.
But theres a few apps i want to use that require root access to use, so my 3 questions are.
1, if i root my Desire do i have to install a different rom? As i like the way the stock Android runs
2, is there a sort of "1 click root" like the iphone jailbreak, as ive seen apps like "easy root" that claim it instantly roots your phone, bit then on here people talk about gold cards ect...
3, if i do root the Desire, will i still get the network pushed OTA updates? As im on vodafone & they havent pushed 2.2 out yet so i want to get it from them, also if i will get them, when i update will it un-root my phone like iphones updatespatch jailbreaks.
Thanks in advance for replys, as i said im not interested in usijg custom/different roms, i only want to use apps that require root access, like cache cleaners ect... but i still want the stock android + sence with my OTA updates.
Thanks

1. there are rooted version of the stock ROM available, check the Dev forum
2. Follow this - http://rootmydroid.co.uk/guides/desire/howto-root-your-htc-desire/
3. No you won't get it, and returning to stock should you want to will obviously remove root. It's best to get your stock Vodafone ROM to have for warranty reasons...
I've been considering rooting my phone at some point. I read in one post that the new OTA update might make rooting impossible. Is this true?
As a follow up question- Seems from the forum posts that some people end up with various problems after flashing. Is it really worth rooting and flashing? What are the most important advantages and improvements?
Thanks

Dude just root your phone. Having complete control over your device is reason enough to do it. Some programs don't even work without it. Rooting is simple too btw with Unrevoked3. Make sure to get unrevoked3 because unrevoked forever will void any chance at a warrenty claim.
I'm a total noobie to rooting and flashing so please excuse me if I have this wrong.
I would be fine waiting for the official OTA update and then rooting and flashing a cooked ROM but I read on some posts that rooting may not be possible after the update. The advice seems to be to run unrevokedforever to get "s-off" and gain permanent root access. My biggest concern with this is voiding my warranty. I already had to return one of these for a bad speaker.
Can I just refuse the OTA until unrevoked gets s-on?
Before you do any rooting; consider the reason you want to root your phone. If you want official OTA updates then don't bother. IF you want to have the freedom and take on the responsibility of doing whatever you want to your phone and the consequences of not fully understanding what you're doing, then root your phone.
Rooting is not for everyone, decide what you want from your phone first, then consider what you'll gain from having root.
You can re-root your phone, but like anything else it carries risks, be ready to buy a new phone for $600 when you blow this one up. Then you are ready to root for certain.
Good advice DIC. I certainly don't want to shell out the dollars for a new phone. My main reasons for rooting and flashing would be:
- Better battery life
- wifi tethering
- having control for reasons I might realize later
- fun
Will the OTA update address the first 2 issues?
Will rooting still be possible after the OTA? If so I can just enjoy the benefits of that and then root and flash if I still want to.
Rooting after the 2.2 OTA
I ran across some older Unrevoked comments that were in the vein that all of their exploits had been plugged in the 2.2 OTA so finding new ones might take time. That was a few weeks ago so who knows what they have now. So if you accept the 2.2 OTA without the S-OFF mod, then you will have to wait for Unrevoked 4(?) to find a new exploit.
S-OFF on the other hand will let you accept any official, locked down update, load you own recovery (ClockworkMod) and from there load su/Superuser.apk.
I happen to be a Linux developer, so I'm interested in unlocking the phone so I can understand the lower levels (below the Android java machine). But I am also cautious, so I would prefer to start with stock and mod the system in bits and pieces as I need and understand it.
S-OFF on the other hand will let you accept any official, locked down update, load you own recovery (ClockworkMod) and from there load su/Superuser.apk.

So are you saying you recommend applying forever and s-off now before accepting the OTA update?
As a "cautious" linux developer what have you done with your phone at this point?
I think I will root the phone with unrevoked3 and just install wireless tethering from the app store for now.
I would also like to update the radio for better performance. I read I can only update to 2.05 without applying s-off and that it can brick my phone if I install it twice. Is this a good idea?
If the official OTA shows up can I run it on a rooted phone? I assume I can. More importantly, do I want to?

I applied the S-OFF mod specifically because I want to use stock as a starting point rather than relying upon a rebuilt or reconstructed MOD from someone else. Not that I don't trust the developers - they do a lot of great work. But with so many files flying around and very little source code behind those mods, I rather build the pieces myself (as much as is feasible). Koush has a lot of his work available on github, for example, and you can see exactly how he goes about replacing a kernel. I've also been able to recompile the kernel from the HTC released sources - now if I can find the configuration files that the Hydra Kernel developer uses, then I can roll my own kernels - again from stock sources.
To address your second question - I've done a network port scan on my phone to identify open TCP or UDP ports and found an unidentified UDP port listening. I posted a thread and some deductive reasoning from other XDA users narrowed down the source to the new Chrome to Phone feature. I'll be able to verify this after the stock 2.2 OTA comes through, but the phone is really a little Linux system under the Java machine that "traps" most of the Android apps. Root privilege bypasses the Android security and the hardware security (NAND lock) and could allow a "root" only app to install something under the hood. The phones are trapped in Verizon's network, so they are hard to get to, but the standard firewall (iptableS) is down by default.
So as Spiderman's Uncle Ben says, "With great power comes great responsibility". If you root your phone, but do not compile your own apps/mods from source, then you must rely upon the integrity of the community and file sharing systems for the mods that you install. S-OFF will let you install stock images and then as a minimum you need a replacement recovery (ClockworkMod) and the superuser package. But from there, you can work as you see fit.
It may benefit the community to have some form of central "Modding integrity verification" system for example where source codes, update zips and md5sums are fully documented so that if you pull down a mod from a file sharing site, then you have a good idea that the file is from the original developer. Then if the developer is good with changelogs and source, the user can feel reasonably good as to the integrity what's running on the phone. It would slow down innovation however.
I like the way you think Starfire. Last night I rooted with Unrevoked3, no s-off. I've only added a few root only apps and removed a couple bloats so far. I'm concerned about not being able to root after the OTA update so I think I will stop worrying so much and apply Unrevoked forever, update the radio, and apply the leaked or a custom ROM.
I like Sense and I would like a kernal with the adaptive cpu clocking, or whatever it is called, so I can improve battery life. Any suggestions?
Thanks much............mm
If you wait for the official ota its gonna be a while until a developer group like unrevoked finds a way to root it. If you want wifi tethering and froyo now I suggest rooting.
youtube.com/user/mejdam
^has several guides on how to root upgrade to baseband 2.05 and downgrade back to stock. Most roms can run on 2.05. If you want to extend battery life I suggest installing a hydra kernal that is undervolted or kingxkernal (if you want more control in oc). Also only way to get true wifi tethering for free is through rooting.

I played with SkyRaider 2.2 Sense and liked it a lot. 2.5.2 sounds even better although I have not tried it because (1) I have my phone S-OFF, rooted stock 2.1 with the stock 605.2 recovery waiting a few more days for the OTA and (2) there was a lot of back and forth with boot loops, sound fixes, Hulu fixes, etc. so I'm letting it settle out a bit. The SkyRaider dev does a great job with extras and themes available through ROM Manager. If the OTA takes too much longer, I may give that one a shot again - and keep looking under the hood.
I think I will play a little wait and see also. I was also leaning to skyraider based on what I had read. I might use it and then patch this kernal http://forum.xda-developers.com/showthread.php?t=760050&highlight=cpu+rom+battery . It is optimized for battery usage. I need to do some homework about it though to see if Skyraider is not already using the same optimization and that it is stable.
Thanks!
