[Q] Rooting advice - EVO 4G Q&A, Help & Troubleshooting

I have an EVO running 1.47.651.1. I used Unrecover3 to root it and have the WiFi tether app working. I don't think this took care of the NAND unlock though.
I'd like to get to a stock 2.2 ROM that's rooted, just to keep wifi tethering working and get some of the Froyo improvements, but don't want to lose camera functionality (3MP vs 8MP), break any of the radios, etc. along the way.
Unrecover3 installed the ClockworkMod Recovery v2.5.0.1 recovery ROM, which enabled me to do a nandroid backup of my current environment.
My understanding is that from this point I need to NAND unlock and flash a rooted 2.2 ROM (please correct me if I'm wrong).
Is there a single comprehensive guide that will take me from 1.47.651.1 to 2.2, preserving ROOT, without any fancy ROM hacks other than the minimum required to keep wifi tethering working?
Sorry for the n00b questions; there are a LOT of guides and threads here and I just don't want to follow the wrong one and brick a new $500+ phone.

look into unrevoked forever, i think this might help you, if not then correct me.

Simple Root
I don't know too much about unrevoked. I rooted using Simple Root. It is very easy. I would suggest you reroot using this method, which will give you nand unlocked.

After you gain root, you can flash a stock 2.2 ROM (search dev forum) I rooted a long time ago so I'm not sure if the newest version of Simple Root will update your radios (Read the thread/site, it may mention it). Search forums to find the latest radio verions and confirm that yours match.
After your have 2.2, I highly recommend that you flash netarchy's custom kernel, which will fix audio streaming, as well as significantly boost FPS, which will make your phone feel like a new phone. You can find that kernel here:

I highly recommend: http://forum.xda-developers.com/showthread.php?t=741294. There have been people stating they've been having problems with simple root.
This TUT looks overly simple. If you are unsure about how to get adb working or how to work with it...just reply here or feel free to PM me.

"You will need to have the android sdk installed, as you will need to use the adb tool."
I'm a lost noob looking to do exactly what rjhollan was asking for. I followed your link to that thread but was lost immediately. I've been reading and searching to try and avoid asking dumb questions but I'm lost on this now. Any help appreciated. I was at least quick enough to deactivate OTA updates so I'm at 1.47....

You got Root and NAND unlocked

Perhaps you used "unrEVOked3" not unrecover3...
unrEVOked3 will give you Root and NAND unlock.
I would suggest doing the unrEVOked forever now.
Look at your ROM Manager and and DOWNLOAD ROM in the program. I would suggest "Fresh".

Whats the best way to update the radio and wimax?

I been waiting forever and not doing any updates due to all the crazy wimax issues. Since the new OTA is rooted would it be safest to update my wimax by running the OTA and re root using the new root method? Please let me know if this isn't the way to go or not. Thanks so much devs for all your hard work. Mod if this is in the wrong section please move.
No, the new root method for the OTA just downgrades everything so you can get access again.
If you haven't done the OTA, I would suggest using the simple root .1 and then flashing something else. The idiot proof guide in the dev subforum is pretty helpful and has a lot of pictures if you prefer that method.
The "How to start over: Fully rooted stock 1.47..." method is very easy and worked great on my phone. As long as you already have root, NAND unlocked, and the Engineering HBOOT, I would go that route. (see thread for the details, Engineering HBOOT 76.2 is the real requirement.)
Yes I have root and nand. Currently running fresh 0.53. I wasn't sure what was the best method of updating the wixmax. Are the current methods out safe yet? Im comfortable in doing the radio. I was just wondering if the OTA updates the wimax differently from just flashing or somehow. Just a little bit worried of running into wimax issues since I do get 4g in my area.

need help, going to root for first time.

ok so mainly I am concerned because of all the different root methods out there. I am thinking I would like to perform toast's method with damage control rom.. maybe fresh.
should I be concerned that I have already performed the OTA update to 1.47.651.1 or only not to perform OTA updates after rooting?
is toasts method pretty much the best method for full root? how is that simple root?
what would be the best way to perform a back up on a non rooted phone? should I just spend for that backup pro in the market?
can anyone explain kernels to me? what are they for and why would I need a new one? are there specific kernels for specific roms?
thanks in advance
You need one of the OTA root methods since you installed the OTA
thanks
ok, so if I am correct that just leaves simple root? will this root give me nand unlock, or can i go to toast part 2 after this simple root?
Just use unrevoked 3 it is by far the easiest
I thought unrevoked doesn't give you full root.
Regular unrevoked doesn't unrevoked 3 does but you need a computer for it
i recommend using this method with all instructions step by step make sure you read thoroughly and skip to the section for after ota couldnt attach link so copy paste it
forum.xda-developers.com/showthread.php?t=721055 this is a very informative and will root your phone and provide nand. i cant speak for unrevoked since i never used it
unrevoked 3 seems to have some radio issues or something? can these be fixed with the radio flash like with the simple root? still leaning towards simple root...
thanks pocky, looks like i have some more reading to do
I rooted my phone about a week ago... did unrevoked, simpleroot, and none of that #@#$ worked for me. Literally ran on 3 hours of sleep a few days in a row just trying to do them, and then I came across this thread:
http://forum.xda-developers.com/showthread.php?t=721055
20 minutes, first try, and boom, rooted, nand unlocked, etc. etc.. It's pretty much the ultimate guide. There are a lot of steps, but, they're all really short and simple. It takes more time to download the files and drivers than it does to root using this method. It's good stuff and I'd highly recommend it.

[Q] HTC EVO Froyo 2.2 Root???

How do i root froyo 2.2 cause i am at stock everything I need to know how to flash a recovery, how to flash radios, how to flash wimax???
Please tell me this is for lulz......since you've been a member since Jan.
I'm assuming you mean "Root" your phone so that you will be able to flash and load the various things you mentioned, in which case you will just have to wait patiently until the developers figure out how to root the phone.
2.2 has been rooted (not sure if using the correct term here) so that it can be loaded on a phone that was previously rooted on 2.1. If you applied the OTA updates from Sprint to get 2.2, then waiting is in order.
If you have stock 2.2 from the OTA Sprint updates, then you already have the latest Radio and Wimax...

Just to make it clearer, 2.2 has not been rooted on the EVO yet.. There are rooted 2.2 custom roms available, but they require you to already be rooted or you will have to root your 2.1, before flashing..
Neewwbb
Yea sorry im new to this site.. anyone have a ETA on the 2.2 root? this su*ks shouldnt have updated.. another thing what does "ROOT" access do really?
Root access basically just gives you administrator access to all parts of the phone. It's not like Jalibraking an iPhone, because the truth is Google doesn't really try to stop you from doing it at all.
You could root your phone just to give yourself the ability to do a backup, and keep everything stock. I was surprised when I bought my Evo, and saw that Google didn't have a way to do a full image backup. Root gives this to you.
You can also use root user access to replace ROM's, and use certain apps that only work with superuser access, or administrator access to put it another way. Examples would be wireless tether from theory of evolution, and titanium backup.
I use a root app called Rom Manager. It's a great way to try new Roms and flash back to stock if you don't like them. I know everyone warns about bricking your phone, and causing damage, but I wouldn't worry about it. You should be fine with anything you find in these forums, or from Rom Manager.

Google doesn't try to stop you, but the manufacturer's do.
It's more like jailbreaking than you think. Both rely on exploits in the software to gain root access to the system. That's why when you do an OTA update, you lose root. Because that exploit is no longer taken advantage up. That's also why it takes so long for people to find a root to the OTA versions. They need to haxxor through all of the code to try to find an exploit.
Though I admit, unRevoked rooting method is far more closely aligned to jailbreaking than a good old fashioned nand unlock.
2.2 I hear is far more secure, so I have a feeling we'll be having a bit of a waiting game.
It's laughable that we have yet another thread discussing this, but while we're on the subject, my personal opinion is that developer efforts would be better devoted to polishing a full EVO-compatible AOSP ROM from the source code up. But then, how would we flash it . . . ?
Oh well, never mind.
My phone is fully rooted with 2.1. I rooted it using the simple/easy 1,2,3,4 process.
If I were to install the ROM Flipzmode provided [ROM] 8/3/10 | Fresh Evo 3.1.0.1 | FroYo | OFFICIAL 3.26.651.6 OTA + fresh goodies Would I still retain my root if I flashed the device?
I'm pretty n00b here too.
Thanks in advance,

I'm new here too....I have a fully rooted Moment (that I learned how to root @ SDX) but I finally broke down and added an Evo to the stable because of the screen's vastness....I purposefully held off on doing the 2.2 OTA because I plan to root my EVO any day now from the things I've read here @ XDA. This site has a lot of great tips on how to root the Evo....but if you need any more just do a bing.com search on "how to root an EVO" and you'll get plenty more. I love my Moment because it's the first phone I learned to root but I like this EVO too!

When the sun has begun to ride through the sign of the Crab, and the river increases until it passes into the Balance. And as the weight of the waters decreases, the plains that before were navigable for boats will then be suitable for riders on horseback. Then, and only then, will you have root.
or not. Just keep your eye on the stickied thread in Q&A - it will be updated as soon as root is found.

Root After Update?

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!

[Q] Temp-root, root, consfused... i just want to run some app, please help!

Hey there,
I have read many topics, guides and post about rooting but more i read more confused i get, so i write here in order to get some assist from fellow desire Z owners.
Situation looks like this:
I have Desire Z with Android 2.3.3 and what i read till now, to root this OS the only possibility is to downgrade it in first place, but the downgrade will wipe out current data (or perhaps i'm wrong here?), which i want to avoid.
Then again i want to root my phone to use some app that requires it, and uninstall some unnecessary components, i'm not interested in flashing custom roms right now, so perhaps there is some way to grant such privileges via temp root without downgrading?
Any assistance will be appreciated.
You will need to downgrade to root, which will wipe all your data.
Here is the best guide
The downgrade guide does have a (very) temporary root, which will allow you to backup your apps and data. It would also allow whatever app you need to run, but not for very long, the system becomes unstable if you leave it exploited.

Ok, understand so follow-up questions:
1. let's say i will do anything till temp-root then do what i want, and then is there a way to close exploit?
2. Or if i will go on, do the full rom backup for example using titanium backup and then restore it after downgrade would it bring back my Andro to 2.3.3 or stay at Froyo?

ad 1. When having temp root you are limited with the things you can do and sometimes the phone does not behave as expected. Temp root does not mean S-OFF, so system partition might not be writeable.
You close the exploit be doing a full reboot of the phone.
ad 2. After downgrade and gaining S-OFF you can install every ROM that is available for your phone. There is a lot of Android 2.3.3 ROMs out there.
VirtuousRom provides some nice Sense ROMS.
The best known "Sense-less" ROM is CyanogenMod 7.1 / 7.2. CyanogenMod 9 is still tested and should soon be available.

Thank you guys for the answers, i did some reading about rooting, adb tutorials, even went through first part of downgrade to get temp-root but at this point i have other questions:
1. I tried to use Titanium Backup to backup my apps, but it don't see them, i searched for solution and it seems that it want's me to update SuperUser.apk but after i do TB dosen't see root anymore, and SuperUser tells that busybox version is wrong, is there any solution to fix it?
2. Is there a reverse guide for unroot and S-ON? i found some using RAGE but i don't know if it would work if i use guide for root?
3. Hboot, is this recommended as i read that this part is where is highest risk of brick?
4. Just for to satisify my curiousity, what will happen if after downgrade i would install OTA Update?
1. Titanium not seeing your apps is weird. Maybe if you get the new SuperUser apk and use that instead of the supplied one when getting temp-root will help (and new su binary)
2. http://forum.xda-developers.com/showthread.php?t=1442988 Revert to stock guide
3. Hboot is recommended. Yes it is (technically) risky, but I have never seen it fail, and so long as you aren't a complete idiot, you can't go wrong.
4. You'll need to redowngrade, no big deal
