Want to go back to stock evo 4g rom unrooted - EVO 4G Q&A, Help & Troubleshooting

I rooted my brothers evo 4g and flashed cyanogenmod nightlies thinking he would love it but he wants his stock back unrooted. i can flash fresh for him which is darn near stock but want to put it back to factory settings incase something happens to it and he needs to return it. I know it was dopey of me but had a few drinks and seemed like a good idea at the time. I love cm7 on my evo 4g but not him. lol Please send instructions for a dummy like myself that is easy to execute. Thank you all in advance,

here you go
how to unroot in two steps

Sweet thanks bro. I know enough about rooting, flashing etc to get the job done but but enough to eff a phone up also. i used unrevoked (one click) and rom manager (one click)..... so I know enough to make my phone sweet as hell but a lot of these terms i cant wrap my head around. Thanks again

anytime man

Just make sure you flash the newest 3.70 stock image.

I'm scared about rooting my HTC Desire.

I just saw a post on Lifehacker, using unrevoked3 to root my desire (id give a link but im new and apparently not allowed), and this seamed like a nice simple process, so i thought id give it a go. but before i do, i just have a few question that id really love a detailed answer or two to, if you would be so kind.
1. Am i going to brick my phone and cry because i bought it unlocked and cant get it replaced because im a poor student?
2. What the hell is this Radio business?
3. Can i put it back to normal so i can get back to OTA updates from HTC when they finally come to there Senses with FroYo (get it )
4. Am I going to lose all my stuff because i cant back it up before i root.
Thats basically it, if you can answer that, id be incredibility incredibility grateful.

1. if u follow the steps exactly as explained, and never touch the phone when it is installing flashing formatting etc etc then u get 99.9% u wont brick it
dont worry im also a student and i bet theres more of us here
2. hmm not sure how to explain what a radio is
3. yes u can, but dont see a reason why, cuz devs update roms quicker and add more functions to them
4. if you just root then no you wont loose your stuff, if you want to install a custom rom then yes you will loose it but you can always back it up using free rommanager back up
This is the main reason why I haven't rooted my Desire yet, despite 1 or 2 friends urging me to. They have Heros. I haven't got the money to replace it and seen as it's on contract I'd be pretty screwed for the next 13 months or something.
Don't worry
Understandable.
I was thinking the same.
It was when I run out of space to install apps and gmail stop working bcoz of low memory space warning.
I decided to take the plunge.
Used unrevoked to root my desire and installing my second rom today lol.
Oh and the radio is the file that contains radio setup for froyo roms.
the one you need for froyo rom is version 5.xx. eg. 32.42.00.32U_5.09.00.08.
so if you are going to install froyo based roms then you need the radio file update or all hell breaks loose.
you can update the radio then install the rom or the other way around up to you.
have fun and ask if you need help.
Was in a similar situation and finally took the plunge today.
Was 10x easier than I thought it would be. Follow the guides and you can't go wrong.

Radio is the part that handles WiFi, gps, 3G and all that stuff. E.g. you have low WiFi signal, you can update the radio to fix it.

Ok guys thanks for all the replies, I'm.defiantly doing it now, my phone alarm has failed to go off too many times now (hey any excuse to convince myself to do it lol) and I want to see if a new ROM will fix it.
Shall I go for OpenDesire or CyanogenMod? I want froyo, and I want it stable (preferably I would still love sense if that's possible).
Also on a side note, I don't want to appear idiotic, I know what a radio is, I just wasn't sure what everyone meant by "update" it, and why you have to do of separately to flashing the ROM.

The ROM's here don't include the radio hence why you need to update the radio seprately, most, if not all, the froyo ROM's will need the latest radio.

Bugs are to be expected but many fixes are to be expected too
opendesire from what i've heard but they lack sense i think, i wanted sense so i chose neophytes rom (it does slow down when i DL stuff from the market sometimes though, i should report it to him)
You flash a radio like a rom, just use unrevoked to do it
BTW use unrevoked with the rooting, easiest thing ever

Is this Neophyte?
showthread.php?t=732246 (i cant post links yet, im sure you can work that out though)
and how do i flash the radio with unrevoked3, where do i even get the radio... file?
Sorry about the questions, normally id just go barrelling into to something like this and work it out as i went, but this is serious stuff this time. I want to be sure.
Thanks again
**** i pressed "SIMLOCK" in the hboot thing, wtf have i done. it said it did something.

i think it means you just locked your phone to the simcard that was in your phone at the time. Rooting it should unlock it again though
BTW here is an unrevoked guide, neophytes ROM and the radio (use the latest, not the leaked one), follow all the instructions to the letter and you should be fine (follow unrevoked's rom flashing instructions for the radio though, thats how i did it and gawd was it easy)
Thank you very very much. With those guides in hand I'm about to do it. See you on the other side ha ha

I'd tried the other way first and my phone wouldn't root (i was really really frightened when a HTC logo came up and stayed on for a whole 24hrs) so i tried unrevoked and it worked like a charm
Lets hope everything goes a bit smoother for you than me
That really was one of the easiest things i've ever done. Thank you so much for all your help, and the ROM suggestion, loving the new sense.

Sorry to ask a stupid question, can i root my desire, keep my current OS as it is and still get the OTA update to 2.2 as it would if my phone wasn't rooted?
I would try the modaco custom rom, search for it. Its based on the latest leaked rom from HTC so its stable, its froyo, it has sense as well as the new 2.2 features like tethering, new widgets, 720p video etc etc
i rooted my phone at the weekend and im loving it!

Agree, also have the modaco ROM. Best thing is that you bake your own rom and only put items that you really need.

Well mate.. I was pretty much in the same boat as you.. Student, wanting to root my phone, didn't know what all the stuff was.. And I'll try and rectify it for you as much as possible, following your points .
1. If you follow the guides which have been put up by unrevoked, or the guide on this forum http://forum.xda-developers.com/showthread.php?t=696189 or our lovely friends over at android.modaco http://android.modaco.com/content/h...e-now-with-hboot-0-80-and-os-to-1-21-support/ then you shouldn't have a problem at all. I was feeling the same way, was confused and really didn't want to risk the rooting process.
2. The Radio.. It's not like a Radio which we use to tune in to FM and AM, think of it as something to help other processes work in the phone. Be it Wifi, 3G, HSDPA, GSM.. All these get updated with the new ROM's (Froyo) and they need the Radio to make them run smoother, and better. Think of a Radio as a driver when you're updating something on a computer. But BE CAREFUL when flashing the Radio, DO NOT, I REPEAT DO NOT touch the phone until it has completely finished booting (2 or 3 times, you'll know when it's finished).
3. You can put it back to normal any time, just by flashing an older ROM on to it, just have a look at some of the official RUU's on this forum.
4. The sort of stuff which you're worried about are photos, text messages and apps? Best way for this is to invest in MyBackupPro, where you can back up all of your texts online etc. For apps and all, why not download ASTRO from the Market? It can back up all your apps and install them again no problems.
I hope this helps

Want to Root But Afraid

Hello all. I'm not new to Android or rooting. I had a Hero for a year and have flashed many roms and numerous other customizations. Also not being a noob to XDA I've been doing my research on rooting my new toy the Evo. I was confident about rooting my Hero because it seemed damn near impossible to brick. However, it seems as though this isn't the case with the Evo, or at least not with 4g. I want to root in the worst way but am fearful of permanently loosing 4g, which brings me to a few questions. But before I get there here's what I've learned through much research.
First, Amon Ra 1.80 backs up wimax.img but it's also necessary to double check that it's done properly as some have had problems with faulty md5sums. Things such as the MAC info can be restored and is available on the box or behind the battery. It's also essential to make sure that nandroid back-ups, or, at least the one containing a wimax.img is stored in multiple secure locations (I always do this with nandroids anyway). Second, if you don't have your original wimax.img which contains your RSA keys you're screwed and have to get a new Evo, which brings me to some questions.
I just upgraded to the Evo a few days ago and have all of the newest updates so is it safe to say that if I root I don't have to worry about messing with the radio/wimax for some time and can just flash roms? Are the radio and wimax radio two different things and if so how can I flash upgrades without worrying about loosing my RSA keys? What is the safest way to upgrade anything other than the roms? In other words if a new radio comes out is it best to un-root and officially upgrade everything and then re-root? Finally, because I can't seem to establish an exact answer to this:is there a such thing as totally un-rooting the Evo? By this I mean, if I follow the steps listed in some of the threads on here for un-rooting does that make everything 100% factory.
I'm paranoid about rooting also because I've switched to Best Buy's service plan which has its pluses and minuses. If I were to root and loose 4g somehow and had to take it back, I'm not sure of how much of a pain in the ass they are in comparison to Sprint. My understanding with the Hero was that it could be totally restored to factory condition by running an official RUU but I can't tell if it's the same with the Evo.
Lol, if you've managed to read all of this, you're probably thinking that I'm so paranoid that I shouldn't root and maybe you're right. However, I liked all of the root abilities I had with my Hero but didn't have the same potential consequences. Can the same be said of the Evo? Should I just wait until there's more development in solving RSA key problems?
Just go for it. Those people who are having RSA key issues have updated their radios through flashing. (I used the same tequnique but never lost my keys...no one knows what's going on yet). Go for it. You will never regret it =).
it's very simple. also squaretrade is the best deal for warranties
unrevoked + unrevoked forever, then you don't have to worry about messing up with 4g as it only flashes recovery and sets S-OFF, no changes to the stock rom or 4g.
Dont be afraid
I root evo's all the time. Some for friends, some for friends of friends who pay me a little $. The point is, I have rooted dozens of EVO's using the latest Unrevoked method. I use a MAC so I don't need to install any drivers (makes it easier).
You WONT have any problems as long as you have not flashed anything crazy to your phone (radio, wimax, etc)>
The worst that will happen is the unrevoked program will say "sorry, we did not get root, but thats normal, please try again."
Sometimes it takes 3 times and then bang you have root.
Also, I have unrooted my phone and its easy as pie.
Don't stress.
If you want some help, I can G-chat you through the whole process or help if you get stuck.
Just PM me if you want help.
To be honest all u have to do is read up on it. Google jonamerica.com(how to root)Trust me I jus rooted less than a week ago so I guess I am considered as a newbie. All in all I have my Evo running like Kentucky Derby Pro. Just gotta look past the fear that u have. If you follow those instructions correctly everything should go great. Check out other forums about rooting to confirm the steps in the link I posted for you. More than likely using unrevoked 3 nothing could go wrong. Ounce the phone is finally rooted, that's where all precaution comes into play. But there's nothing that a (nandroid backup) can't fix. Read up on that also. GOOD LUCK!!!

You seem like a cautious person ... I am as well. There are lots of really bright people developing for the Evo, occasionally they push the envelope. That's ok with me, because their creativity is what makes all the good stuff available. With that said, the Sprint/HTC stock offering isn't too bad, but if you're like most of us ... it quickly won't be enough for you.
Go ahead and root ... just use good sense, and don't assume that everything that gets posted is ok ... sometimes, it takes a little time for things to shake out. For instance, I still haven't jumped to the new PRI and Wimax radio. Some have had great results ... some have been not so good. I expect to update ... but in the meantime, still enjoying all the benefits of some great custom work. Go for it ... you'll be ok.
And by the way u don't lose 4g ounce rooted. Certain ROMs that u flash don't have a 4g fix. So jus make sure u know what ur flashing.
r0cky.Da.3v0.SU
Thanks all!!
Wow! I wasn't expecting so many responses. Rather than multi-quote everyone who posted I just want to say thanks to all of you!!! I haven't rooted yet but will get there. I'm still doing a little more research before I take the plunge.
Hypothetically, if a new Wimax radio comes out how can it be installed safely, is it best to unroot and officially upgrade then re-root? What have you guys been doing when upgrading the radios, since it seems best to not just flash them.
In the past, I've always just flashed the new radio over the rom. With the new radio that has had some problems ... it's not the process ... it's that it's not the official release. With this kind of stuff, patience is a virtue.
I was teribbly afraid too. I put 2 weeks of research before rooting. The first time I did it I messed up, but then the second time it worked. You will not lose 4g unless you are using CM6.
Get a radio that's very compatible with your rom. It will be safe to flash jus hip cache and dalvik cache and u should be fine. Male sure to nandroid backup before doing so.

I'm with you. I just purchased my new Evo on Oct 1st and it came preinstalled with OS v2.2.
I rooted my previous Hero just days after the first exploit was found and it was quite easy. The Evo rooting and rom installing process looks much different however and I'll need to continue researching this one a bit longer.
I'm not a fan of one-click root methods and would much rather stick with good ol' adb commands, so I think I'm going to wait until a new command line method comes out that works specifically with 2.2. I read about the one method so far that works with 2.2, but I'd rather not downgrade anything.
Current phone info:
OS 2.2
Build 3.26.651.6
PRI 1.71_003
PRL 60671
I have a feeling that you'll search and research for a good long while, then, like a kid on Christmas eve who just can't wait and has to shake the presents, you'll root. Then... Happiness!
Sent from my Virus Infected Evo using the XDA app.
OP - I'm in the same boat as you. I really only want to root for WiFi tethering, but then I found out that PDAnet and EasyTether allow cable tethering, with PDAnet also offering tethering over Bluetooth. So as of right now I'm still a bit undecided, but am still trying to read up on all the available options.
My advice to you (as I was burned by a bad Unrevoked patch), is wait a few days to apply things that mess with your radio. This will sort out the bugs and whatnot.
The Unrevoked team didn't test a patch properly and they killed 4g for a lot of people.

[Q] newbie rom question

I am addicted now into customizing evo the way we should all be able to do. If I were to add a custom ROM, and for whatever reason need to take my phone back to Sprint how would I put back all original Sprint OS.. or whatever the.proper term is for it?
Next, what seems to be the best ROM out there for the EVO?
Once again I trust this site with all the knowledge and help, mad props to all on this site

Yes you can revert back to stock. You can find threads in the dev forum to "unroot" if you so need.
There's really no best ROM though. Try a bunch and see what u like.

Depending on your hboot version, you can probably follow these steps here:
http://forum.xda-developers.com/showthread.php?t=829045
Make sure before you start though that this method is the correct one for your phone.
And also, might I suggest trying the Stock Turbo by Ricsim78 and the ReEngineered 3.70 rom if you like stock roms. They are two of my favorite sense roms and they are almost completely stock with a crapload of enhancements to make your phone oh-so-fast. Good luck to you!
Just like Leukay said, that thread will probably be the one for you. Make sure you follow the directions to every LETTER. It will also help if you can add the copy/paste feature on MDOS.
My favorite stock sense rom is the Burnt Droid rom. there are 2 verisons of the download, one is with a custom kernal which I use and one with the latest stock kernal which i believe is #15 or 17 which will definitely work for you.
Good Luck

[Q] Making the switch from e3d

OK so I have decided I wanted to try the e4gt and possibly bag the e3d for now. The phone will be here stock tomorrow. I am fairly familiar with htc devices but not with samsungs. I had the e4gt on launch day but there was too many bugs for me. Tried a custom rom still too many bugs.
Anyways I am back to try again. I have forgotten everything about flashing rooting ect. I am wanting to try out the new ics rom but I need help.
What is the best way to try this out without bricking or making it where I cannot return to stock to return the phone just in case. Any advice or pointers are greatly appreciated.
The e4gt is quite a different system than the htc devices so I am confused with all the different posts there is out there.
Thanks again
James
This should pretty much take care of everything for you, once you get root and cwm, flashing is the same as with HTC. its pretty difficult to brick this phone unless youre using Odin, which this process does not require. so theres virtually no risk as long as you read the directions. after you root you are gonna want the cwm option fb15 to fb21 if you want to flash an ics rom
http://forum.xda-developers.com/showthread.php?t=1342728
here you can flash Calk's touchwiz overlayed ics:
http://forum.xda-developers.com/showthread.php?t=1513615
