I've just recently registered but have been lurking for a while and doing a lot of reading. I've seen there are a bunch of different options for rooting a evo. Also seems like there's a lot of out dated ways to root as well. I'm still new to this and have some questions. Looking to have full root access. As far as I understand it, I will need to run a rom after rooting the device? Will I still be able to receive sprint updates as need once I root? My main reasons for rooting is for the wifi teether, maybe overclocking to speed it up a little bit and to remove the factory sprint apps. I did have a friend tell me that once his buddy rooted his evo he noticed his battery life was a lot better. Anyone experience that? What other info do I need to provide you? Thanks
Update: Was running 2.2 froyo till my phone just did the 2.3 gingerbread update and now my internet doesn't work. Is there any way to root now or am I screwed and have to deal with sprint?
You don't need to flash a rom after rooting but you definitely can. As far as updating, I'm not 100% sure about sprint, but I think you need to be stock to receive an OTA update. For rooting your device, use unrevoked, its an incredibly simple one click root program.
Unrevoked is the quick and easy way to root. Once rooted you WILL NOT get Sprint updates. If you get your 2.3 Sprint update and apply it you WON'T be able to root.
You can run stock 2.2 Android with Sense rooted and not load any ROMs. I do not know if you'll be able to wifi tether by only being rooted. I do know that there are several ROMs that have Android 2.3 Gingerbread and have wifi tether working so if you do root your 2.2 install Amon_Ra recovery then flash Cyanogen Mod 7. Instructions are on his Wiki which I can't post a link to since I'm new forum user here.

Should I even worry about the OTA updates then?
I picked up a Desire HD from Telus about a week ago, and stupid me, I got over-excited and did a software update which upgrade my Android version to Gingerbread 2.3.3, which added the OTA update to my phone
Now it seems like rooting my phone is really tough. I don't think Unrevoked has released a version for Desire HD yet, and I can't even temproot my phone using this guide: http://forum.xda-developers.com/showthread.php?t=905003 (Gingerbreak seems to just hang, and the other method gives me an ioctl error.
Does anyone know of another method to root a Telus Desire HD phone? Or has that not been developed yet? Feel free to PM me if you need more details. I'm not overly techno savvy, so if you need additional info from my phone, a few steps for me to get you that info will be super helpful!

Edit: I should also mention that I tried using the Gingerbreak app, but that one also hangs while attempting to root. I assume the code for the app isn't too different from doing it with adb shell though.
Can't root gingerbread yet.

I get that you can't perm root Gingerbread yet, which is why I'm looking to downgrade my stock Telus Gingerbread ROM. The problem with doing that is I need to be able to temproot my phone first, which is possible on some phones (hence the existence of Gingerbreak and Unrevoked). I'm just wondering if anyone can at least temp root a Telus Desire HD so that I can downgrade my ROM.
Any news on TELUS DHD?
Hi.
Did you ever get answers for your phone?
I have the same phone and would like to "unlock" it. I also am on 2.3.3
I don't even know if it is possible to stick with the TELUS provided rom, but have the device rooted.
Let me know if you have any update.
Also, one last thing, when you attempt to root and it fails like it happened to you, are you left with an unusable phone, or is it just a matter of "reboot" and retry at a later time?
Thanks,
Zoltanar
I would also like to know if anyone has confirmed a method that works or if someone can simply tell me this won't be possible, going to try to do it today and will post up results, but if anyone can let me know their experience it would be much appreciated,
Thanks all.

This tutorial worked great for all who need want to do it.
Edit:after installing a rom on it I've got a usb brick, everything else works though, don't know if this is coincidence or because of the method though.

I don't think it will be hard for any of the talented developers we have here to root the OTA ROM. Obtaining S-Off after accepting the update might be another matter, and accepting the update on a rooted but otherwise stock TBolt might break root. But as long as you've rooted before the GB update I'm sure we'll be fine. It's the poor suckers who haven't rooted waiting for the update, and once it comes decide they want to root that I feel sorry for.
don't install the OTA until it's cracked by the devs, simple as that. i give it a day or two and it would be rooted. they never close all the root exploits.

As said, the BootLoader and rooting the OS are two different things..
That being said... I expect the DEV's to root upcoming GB updates... After all, chingy51o just created Gingeritis v1.2 from a new "non-test" GB rom... and its rooted.

Building a rom that has root access is not the same thing as gaining root access on an existing installation.
Its not really the same thing, but think about having admin rights on a machine with windows already installed, verses installing it yourself. If someone else has secured the machine, getting admin could be quite hard (stfu peanut gallery, I know that's only in theory).
If you install from scratch though, you just have to tell it to make you admin
What this means though, is with source, bootloader is everything. They can lock the rom down three ways from sunday, but if devs have source, and an open bootloader, we can install WTF ever we want on the phone.
Its silly that they are so quiet with updates its not like they are launching a spy satellite but anyway. Phase 2 out of how many phases? Just curious what their proper procedure is.

I understand the analogy of admin rights on windows already vs a regular user trying to get admin rights after the fact.
I'm not a developer, nor do I know the first thing about creating a "custom rom"... so my thought is... Chingy51o used a "GB leak that is newer than the last" as the base to create Gingeritis v1.2 which is rooted.... How much harder can it be for the DEV's to put out an already rooted/busyboxed version of that GB ROM Chingy used as the base?
And if that is possible... then the S-Off/Root processes (where you flash to older rom first to exploit...) could be used by those who took the upgrade... and flash the already rooted ROM, no?

You might not be able to downgrade once you accept the update, this happened on the Incredible. They had rooted 2.1 on the Incredible,then there was an OTA (still 2.1) which required you to downgrade to root, similar to what we're doing now. When Froyo came out, of you accepted the OTA there was no way to downgrade and root. We (I personally) had to wait for them (the unrevoked team) to crack froyo to gain root access. I would suggest you root now, then wait for someone to release a rooted version of the OTA. Just my experience in the matter.

I'm not saying you won't be able to after the GB OTA on the Thunderbolt, but on the Incredible after the Froyo OTA you could not flash an older RUU. That's my knowledge on the subject.

Sorry, my memory on each phone and their specific quirks is fuzzy (between the D1, X, INC and TB, and add in the NookColor and Xoom, and I sometimes have troubles remembering)
But I do remember a friend had sent me his Inc for my then fiance (now wife)... he didn't S-OFF, took an update and lost root... So when I got it, I had to jump through a few hoops to get her's S-OFF and rooted as the Unrevoked tools didn't work on that version yet.
Are you thinking that the Dev's wont be able to pack a pre-rooted/busybox'd/SU version for those with S-OFF and root already?

I think they absolutely will be able to, in fact I almost know so. I'm simply not sure how easy it will be to obtain s-off after accepting the update. I could be wrong, it's happened before, I think it was on a Tuesday...
Edit: In other words, I think it would be wise to obtain s-off while on 2.2 then wait for one of our wonderful developers to provide a rooted version.
It seems HTC's 2.3.4 Gingerbread builds are quite secure. I guess all builds of it are, not just HTC's. I have just noticed a trend with HTC's builds being rather difficult to obtain even temp root.

Hopefully people are looking into it now that the new GB rom has leaked.
AlphaRevX managed to unlock the bootloaders on the evo 3D and sensation. Don't see what would be diffrent on the Thunderbolt if it gets locked down again.
Hello all,
I am fairly new to android, the Epic is my first android phone purchased on launch day. But I am very new to HTC and the EVO Shift. I just purchased one for my wife. I was wondering if someone could point me to some instructions, or just give me some, on how to best install clockwork and a rom. Her phone came with the latest update. Basically I would prefer to remain stock with just root and wireless tether. If anyone could help me accomplish this I would greatly appreciate it.
You are going to have to look at the temp root thread that is right here in this forum since she is on the newest update. You are kind of limited to what you can do unless a permanent root solution is found. Wireless tether should work. I think you may be able to remove or freeze the bloat using somethin like titanium but it will probably come back when you reboot. Can't use any custom roms yet either...

The only root that has been gained on the evo shift GB update is temproot no perm root yet so on a simple reboot you lose root, there is no recovery and no custom roms while temp rooted, there are a couple threads dedicated to this stuff here already

Yeah I knew there was only temp root but I saw some roms that were gingerbread with root. So I didn't understand how that was. I thought maybe if you could get clockwork installed with temp root you could still flash a rom. So are the gingerbread roms only for people on froyo? Can you downgrade to froyo and upgrade to the gingerbread rom? Also what do you use to flash roms. With samsung you have odin. What do you use on htc? I see mention of ruu but have seen nothing on how to use it or where to get it. Sorry for so many questions and being really new to this side of the pond.

Flashing clockworkMod while temp rooted isn't going to work, as soon as your phone tries to reboot you lose root. So you can't access Clockwork, which is how/where you flash ROMs. Currently there is no way to revert back to froyo, the new bootloaders do not recognize the froyo RUU. Basically until a perm root solution is found, temp root is the best you can do.
The ROMs that you see are for user that rooted while running froyo and never took the "official" update from HTC.
Did you buy your phone brand new or used? Go to settings about phone, software information.
If you have Android 2.2 you can root your phone. Otherwise you are screwed until HTC unlocks the bootloader.

He said brand new so that means it came with 2.3.3
OK I will wait patiently until perma root has been established. Thank you all for all of the information.
I am moving my question to a new thread here in the hope it will get more attention:
OK, Firstly, when do I need CWM?
Secondly, I have downgraded my Desire Z from Gingerbread to Frodo and obtained root, S-OFF, etc, using gfree. I know I can upgrade back to gingerbread and want to do this but only if I can do it without losing root. I've seen lots of posts saying gingerbread can't be rooted and one or two saying it can, and others that deal with the upgrade but simply don't say if root will be lost. I assume that if I just install the OTA update offered by HTC, that will undo everything I just did in downgrading and getting root. If I understand correctly, having root is mostly a property of the bootloader and its configuration, so is it possible to re-install gingerbread but without overwriting the bootloader so as to keep root? Is RUU relevant to what I am asking? I hope its OK to post this here, as my only other option seemed to be to start a new thread. Thanks, THANKS!
CWM stands for clockwork mod.It is a custom recovery that replaces the standard recovery,and has much more options than the original.The recovery is like between the bootloader and the actual OS.It allows you to install custom ROMs,partition your SD card,and lots of other stuff that can't be done within the OSor the bootloader.I don't know about your phone in particular,but most HTC'S have Gingerbreak,which allows you to root on Gingerbread,even if it is s-on(although needs an unlocked bootloader though).
Keep this thread updated.

Thanks, I will read up on Gingerbreak and see if it can help with the GB upgrade. My bootloader is unlocked and I have S-OFF, but I only heard about Gingerbreak from you. Is it a tool produced by an xda-developer?
I assume CWM is only for the OS and bootloader and I would still use my Titanium backup for Apps, or can CWM do both? On a completely stock/standard HTC phone can I use CWM first [before doing anything else] to back up the stock HTC ROM that the phone came with? [That would be great if I can!] Is it the best tool for specifically this? Thanks again.
CWM takes a Nandroid backup to your SD card,which is the OS,kernel,apps,data on internal memory,etc.It's better than Titanium backup in this regard,because even if you mess up your phone you can just revert to this backup.It's the best app I know of for this.Only drawback is that it can't operate within the OS,but even then you can use ROM manager which you'll install anyway to boot into it.I think Gingerbreak is developed by a XDA developer,that's where I saw it when I was rooting my Wildfire S.

Thanks again, last night I took 3 hours to search xda-developer and read what I could about Gingerbreak. Here are my conclusions which may or may not be right:
Everything I read was to do with using Gingerbreak to root a phone that already has GB running on it. As I understand it, it works for some phones running gingerbread, but not all phones. I did not read anywhere that any one has used gingerbreak to root GB on an HTC Desire Z.
I would love to hear from anyone who has tried out gingerbreak on a Desire Z. I think someone more knowledgeable than me, who knows how to get themselves out of trouble if gingerbreak doesn't work should try this. For me I think its not wise at my present level of knowledge.
There are many places in xda-developer [some even with a 2012 date] which say that a Desire Z running GB cant be rooted without downgrading to Frodo. Some of these appear to be knowledgeable developers that would have surely considered the gingerbreak oprion. So I submitt that this strongly suggests that gingerbreak doest work in this case. However it would be great to have this confirmed - perhaps from someone who has tried it.
So I return to my original question:
I know I can upgrade my Desire Z back to gingerbread and want to do this but only if I can do it without losing root. I've seen lots of posts saying gingerbread can't be rooted [on a Desire Z and some other phones] and one or two saying it can, and others that deal with the upgrade but simply don't say if root will be lost. I assume that if I just install the OTA update offered by HTC, that will undo everything I just did in downgrading and getting root. If I understand correctly, having root is mostly a property of the bootloader and its configuration, so is it possible to re-install gingerbread but without overwriting the bootloader so as to keep root? Thanks.
1)Most phones running Android 2.3.3 work(my Wildfire S worked running 2.3.5)
2)I think if it doesn't work it will just say 'Exploit failed' or something of the sort,it's highly unlikely that it would mess the phone up,and even if it did,you could just restore the nandroid backup.
3)You haven't read about Gingerbreak on the Desire Z probably because most people don't stay with the stock ROM after they root it.
And even if Gingerbreak fails,you have a s-off bootloader.So there should be loads of other ways to root it,although they may be complicated.I'd say just try your luck,take a nandroid backup if you're scared,and try Gingerbreak.There's an 80+% chance that it will work,as the desire z runs 2.3.3 AFAIK.
A better idea would be to root, s-off, unlock bootloader at whatever (so in your situation froyo), then flash CWM, and finally flash a ROM. There's a 99% chance somebody made a working ICS ROM for the desire z which was a very popular phone

Good point,but I think he wants to upgrade to the stock GB.....otherwise why does he need to root it again,as there are MANY gingerbread custom ROMs,let alone ICS.If he wanted to do that,it would be easy for him as he already has s-off and root now all he would need is CWM and a good ROM.
Keeping root when updating Frodo to GBread or choosing a good rooted ROM
Thanks for all your replies. OK here is where I;m at: I have 2 phones, the Desire Z and the MT4G slide. They were both running stock GB unrooted when I got them. I have downgraded the Desire Z to Frodo to get root and S-OFF having read that was the only way to root it. But I would like something later than Frodo [or GB] as long as I can keep root and it is more functional. I have been searching xda for nearly 4 weeks to see if there are any ROMs with full functionality for these phones. A ROM based on ICS or JB would be great, but in every case that I look into I run into problems. Some have issues with camera or video not working, some with leds or the keyboard back light. One says the audio doesn't work. Other ROMs sound really good but they don't explicitly state they work for either of my phones. As all these things work with GB I don't want to go to ICS/JB if it means I'm loosing functionality. It is only for this reason that I asked about returning to GB for the Desire Z whilst keeping root. Root is essential to me as I have a lot of plans that involve running SSH, Telnet, VNC, etc. There seem to be some great ROMs out there for the MT4G but I am told that my MT4GS is completely different and they wont work on it.
Part of my problem is I don't always understand what I'm reading because of terminology. There are references for example to the Glacier or the Sensation, but I haven't yet worked out whether a MT4GS is the same as Glacier or if Glacier refers only to MT4G, in which case does MT4GS have another nickname? I searched the WIKI for HTC phones, but the MT4GS isn't even listed there.
I'm new to Mob phones and Android, but have been programming and a Linux user for a very long time, which has taught me to be cautious and research well before jumping in. Hence my posts for advice / help here. There's nothing better than finding someone who has done it before who can tell you how successful it was. Appreciate any light you can bring even to just one of these matters. Thanks.

You're right,ICS and JB ROMs aren't too stable,although the cyanogen mod alpha 6 for the doubleshot seems kind of stable,look here http://forum.xda-developers.com/showthread.php?t=1644084
(Take a nandroid backup of gingerbread though,in case you come to a time where you can't take any risks with your phone)
EDIT : CM9 is listed as stable here in the cm download centre http://download.cyanogenmod.com/?device=&type=stable
And for the desire Z, there seem to be stable cm7 ROMs.Just take a nandroid backup of froyo,you can't go wrong with that.
(P.S.You probably saw these already,but just in case you didn't.)
