About to root android 2.1

Hi guys, My name is Mike and I would first off like to thank everyone for their time and devotion to making our android phones so much better with rooting, roms, etc.
I am very new to messing around with any sort of programming I.E. command promts etc. I am going to attempt to root my phone (Sprint HTC Hero 2.1) using the instructions from this website....xda: How to root sprint 2.1..
Im creating this post to hopefully show others who are afraid to take the risk that it cant be that hard with a guide like in the link above and also just in case i need to ask questions. Like I said before I have no clue as to what the hell I am actually doing Im just tired of reading and feel its time for some doing. Currently the files are downloading as I type so in the meantime if anyone could suggest a kick ass rom and some links possibly it would be much appreciated.
HERE I GO lol

alright i downloaded hero root, htc sync, and sdk. So here is my question is this the correct location if I unzipped hero root into the tools folder of sdk? :
\Users\us\Downloads\android-sdk_r06-windows\android-sdk-windows
the reason I ask is because I don't know if the command prompts are in unison with the names of the locations.

Root help please

So I finally got my G2/Vision, I want to perm-root my G2. But I fail so much, I can't even put Visionary into my G2.... I downloaded Astro, but I need to place Visionary r14 in my SD, but I can't find a place to put it.
When I look in my SD through windows, it shows me a LOST.DIR, .Trashes, .Spotlight-V100, .fseventsd, .android_secure, Android, etc. etc. But I still can't find the spot to place Visionary, Help?

place it in that folder

Haha, I figured I'd just dl it off the internet through my G2. It worked. Configured it.

Word to the wise, stay away from visionary. Use rage.

Whats the difference? And... What happens if I already used Visionary?

If you used Visionary and it worked for you, then that's great.
I also try and steer folks away from Visionary myself. Quite a few seem to end up with a lot of problems after using Visionary. The "rage" method of rooting is a lot more reliable, it's just that it looks a lot more "scary" to newcomers because there are commands you have to type in and run on your PC and phone. But if you read up on it, and ask questions if you don't understand, then follow the instructions carefully, you'll be fine - and even if rage goes wrong then you won't end up with a semi-brick, you just won't get root (until you fix the problem).

Ohhhh, Ok. Yeah I couldn't get Visionary to work until several tries. Took me a while. I was supprised I hadn't bricked my phone already. But now I'm pretty satisfied with CM 6.1 w/ MattedBlues theme. Sucks though I couldn't get it to work with Virtuous. I really like Sense alot more than the stock Rom (I consider CM 6 to be pretty stock)

Hope this helps!!!

+1 on the reliable and +1 on the scary!!!!
I am very new to Android,...I've only had my G2 for about 2 months...I ran Visionary temp root without issues (r10). When I tried to install in r14 to perm root, I encountered a myriad of errors, and decided not to root.
But I just couldn't give up on it....two weeks ago I got food poisoning, which rendered me useless and home bound, I decided to attempt it. I decided to use the rage method, but found that the instructions assumes that you know something about rooting. There are alot of people on this forum that are willing to help (steviewevie was one of them) to get you your through what ever hurdle you encounter.
Personally I found the rooting process very rewarding as I now have less of a vague idea of what is happening in my phone (ie not as lost as before).
Some of the basics:
- Install adb on your pc (not that scary), and read a bot on it...understand what some of the basic commands are trying to do. (see the rooting guide for those commands)
- set your path on your PC to point to the correct directory from where you are pushing (There are a few forums here that will guide you setup by step on how to do this)
-Follow the instructions to the T, and you should be ok.
Click here to go to the thread that these guys helped me while I going through the process. Post #4 makes reference to the path on your pc.
NOTE:This Path should point to the location where you have your adb tools and location of the files you are trying to push to your phone.
Post #17 goes step by step on what you need to do, and how the lines on the terminal should look like.
This is really not that difficult once you get your bearings, and for me it was a lot of fun...actually a little bored with the phone after having done this.

Put (SOLVED) in your thread title please.

You all seem to suggest to not use visionary but use rage but from what I saw yesterday we had 2 "bricks" from people rooting with rage, compared to none from visionary

If you know how to read, you can safely root using rage. Just read over the instructions a couple times first.

If you know what your doing both methods are as safe as each other. From what I can see there is a larger margin of error using Rage, however its entirely in your own hands, so as long as you make sure you input it all correctly it should be fine.
Both "bricks" yesterday were recoverable, and both times the user was sure they followed it all correctly, it just seems that their rom corrupted during the process so ended up stuck on a bootloop.

Thank you both (i'll add the to your thanks meters when I have some available). Just need to find how to fully reverse the rage method if needed.

Are you sure the corruption didn't stem from an earlier unsuccessful attempt to root with Visionary ?
I've yet to see a thread where someone has done something bad to their phone via rage, all it does is fire up a ton of process to use an exploit which gets you root. That can't corrupt your phone on its own.
Do you have some links ?

[Guide] How to Root, Unroot, S-OFF, and Flash ROMs your G2!

I've been getting a lot of requests from people, simply asking how I went about Rooting and Flashing new ROMs to my lovely G2 Vision. Well, I'm gonna make a guide with step by step instructions on how to do so. This Guide will teach you how to Root, Unroot, S-OFF (security off, to enable development), and how to Flash a new ROM to your G2.
NOTE!: I am NOT a developer, and i will only accept thanks for putting this information together, I did not create these instructions. Thank the individual developers/posters for their information!
WARNING!!: These procedures are not only dangerous if you don't follow them to the point, but also void the warranty on your phone!! Following these steps incorrectly can brick or otherwise damage your phone!! XDA-DEVELOPERS as well as MYSELF accept NO RESPONSIBILITY to what happens to your phone!!
Just in case you didn't get the message.. WE AREN'T RESPONSIBLE. HACK AT YOUR OWN RISK!!
I will do my best to help anyone along their way, but you've been warned. We aren't here to take the blame for a mistake, we're here to help you do what you're seeking to do.
Got it? Let's proceed, shall we?
First off? The Rooting!
ROOTING: Allowing the phone and it's softwares to have access to the "Root", or complete control, of the phone itself.
This procedure includes two major steps. Temporary Root and Permanent Root. The rooting process for the Temp Root will revoke itself after a reboot. The Perm Root method will not. The rooting process is not complete until the Perm Root process has been finished and the Root is still active after a reboot!
Temp Root the G2:
1. On your phone, go to Settings > Applications > Development > and make sure USB Debugging is ON (it MUST be ON) and make sure Fastboot is checked OFF (it MUST be OFF).
2. Visionary was removed from the Market, please download it from Here instead. Save it to your phone's memory card, then simply open it on your phone with any file manager app. (like Linda File Manager for free from the Market, for example) Find the visionary .apk file in the file manager and click it and follow the prompts to install it.
3. Install Visionary from Modaco.
4. Once installed, open Visionary and check ON Temp Root After Reboot, and check ON System R/W After Root. Then click TempRoot Now, and wait for it to finish. DO NOT CLICK ATTEMPT PERMROOT NOW! We'll get to that momentarily.
5. Once it is done, you have temp root and can use rooted apps without rebooting, OR continue to the next procedure to gain persistent root access.
Perm Root & S-OFF the G2:
An explanation of what S-OFF is and why you might want it - S Off means security off for your HBoot mode (aka Bootloader). The bootloader is what allows you to flash updates and write to the file system of your phone. By turning the Security OFF, we can flash any updates/ROMs we want without the phone checking to see if it is an official update or not.
Let's continue.
1. Download the rooting files: Right here.
2. Extract the files somewhere to your computer.
3. Plug your phone in via USB cable and mount the SD card so we can transfer files to it.
4. Copy the .ko and .img files from inside the extracted folder from step 2 to the root of your sd card on your phone (NOT in any folders, just on the SD card itself).
5. Unplug the phone.
6. Go to the Market on your phone and download/install Android Terminal Emulator (free).
7. Open the Terminal Emulator app and type the following with hitting enter at the end of each line (to get the touch screen keyboard to come up hit the menu button then toggle soft keyboard):
Code:
su
cd /sdcard
insmod /sdcard/wpthis.ko
*After typing the last line, you should see an error saying failed:
(function not implemented). If you DO see that, you have done it correctly
and can continue.
8. Now, type the following line in the terminal emulator hitting enter at the end of the line.
Code:
dd if=/sdcard/hboot-eng.img of=/dev/block/mmcblk0p18
[the last part is mmcblk(zero)p(one)(eight)]
9. After you have typed the dd line for your specific phone, it should say something was written etc. Now, type the following into the command prompt with hitting enter at the end of each line:
Code:
sync
10. After that is done, reboot the phone. When it boots back up, turn it off and back on holding down Volume Down and Power until the HBoot screen comes up. Confirm it says S-OFF at the top. If so, you have S-OFF.
11. Now, to get permanent root, turn the phone back on to get to the normal home screen.
12. Open Visionary and Uncheck TempRoot on Boot and click Temproot Now.
13. Then select Attempt Perm Root Now and the phone should reboot.
14. Once the phone reboots, open Terminal Emulator on the phone and type su and hit enter. If you get the # symbol, you have permanent root access and S-OFF!
Next? The ROM Flashing!
Alright, guys. If you've made it this far, You're golden. Grade A directions taker, In my opinion. Let's get to the last step, yeah?
Getting Recovery:
1. Once you have done the above to procedures, open the Market on your phone and search for ROM Manager (Free).
2. Install it.
3. Open the ROM Manager app and click Menu, then Settings and turn ON Delete Recovery.
4. Click Back and then select Flash Recovery.
5. Choose your phone model and then let it flash the recovery.
6. Click Reboot Recovery and you should be put into the custom recovery image screen. If so, you are all set.
Now, to Flash a Custom ROM:
1. Head over to theunlockr.com's ROM page here and choose your preferred ROM. Download it and save it to your computer.
2. Once it is saved, plug in your phone via USB cable and mount the SD card so we can save files to the sd card.
3. Copy the ROM's .zip file over to the root of the sd card (NOT in any folders on the sd card, just on the root of the card) (do NOT extract it, leave it as a .zip).
4. In the custom recovery screen, Backup/Restore and backup your current ROM.
5. Then select Wipe Data.
6. Then select Apply .zip from sd card and choose the ROM you downloaded earlier.
7. Once it is done flashing, click reboot system. Once it reboots, you are all set!
Congrats! You've flashed a new ROM to your G2! Hopefully..
There are some known issues out there, that prevent mostly the Rooting process. I'll touch on one of them real quickly.
The main issue I experienced was that I accepted and flashed the update that T-Mobile released to prevent Rooting. I've found an article on how to downgrade your firmware to pre-OTA, so that you can Root. Try this if you have severe issues trying to complete the Rooting process. Thanks to Apache14 for this info!

There's now also a process to UNROOT your phone! Here's the link. Thanks to David Cogen from theunlockr for all this information!!

Thanks for the effort. But I'm not sure what this is achieving other than duplicating the existing rooting guides in the dev forum.
Also this isn't a very up-to-date guide, it only seems to use one version of "wpthis.ko" and it isn't clear if this is for pre-OTA or post-OTA G2s. And it doesn't cover the DZ either, so it's not a "Vision" guide, just a G2 one.
The existing wpthis.ko was found by scotty not really to work properly anyway, and the newer gfree method of rooting (fully documented in the Wiki) is more reliable (though still does not work with all kernels). And you know Visionary hasn't been updated for months now, right ?
Sorry if this seems like I'm just trashing your guide, but I don't see how posting old information is going to help people ?

It may be old, but I had yet to see a collective guide on xda developers' website about rooting, s-off, and flashing the 'G2' vision. In which I clearly stated this was for the G2. Not the Desire Z. This is the only method I knew about, and this guide was for a few select friends, and whomever else felt the need to use it. Its okay if you don't agree this post was helpful. But come on. This was the surefire way I used to root my G2, so I'm spreading the knowledge. Let not hate.

So visionary still works right?
Just checking before I go threw with this.

Exactly, it's old. If you're writing a new guide, why use very old, out-of-date info, when you could easily provide the latest info (e.g. from the Wiki).
Yes, it's a collective guide, but one with old info in, so I don't see how that's helpful.
Your guide uses wpthis.ko, but makes no reference to G2s that might be running the original shipped ROM, or the OTA update. So this will only work on some of those phones.
Your article talks about something that T-Mobile did "to prevent rooting". I don't know where you got that information from, but it's not correct. T-Mobile did nothing to prevent rooting, because the OTA came out before root was fully achieved. It's just that the way of disabling NAND write protection needed to be done differently on the OTA (more as an accident than anything that T-Mobile did).
You refer to Visionary as a "sure-fire" way of rooting. Are you sure ? Have you seen how many phones have ended up stuck in a boot loop after using Visionary ?
Also, I find it kind of weird/interesting how your guide points people to another website to choose their list of custom ROMs. Why not point them to the dev forum on this site ?
Sorry but your guide is full of mistakes and out of date. You haven't even posted it in the right forum, this is the Q&A forum.

It worked for me. Bottom line, That's because i did it step by step and actually followed directions.
Old or not, IT WORKS.
If you want to make something better, then do so. Otherwise, silence your lout. Thank you.

Thank you for this write up. I was having problems getting my root to stick even though it was showing s-off but I followed your steps
10. After that is done, reboot the phone. When it boots back up, turn it off and back on holding down Volume Down and Power until the HBoot screen comes up. Confirm it says S-OFF at the top. If so, you have S-OFF.
11. Now, to get permanent root, turn the phone back on to get to the normal home screen.

AND IT WORKS!!!!

You're welcome, fellow G2 owner.
Why don't you join my group, for those who love their G2? just check my groups in my profile, hopefully we can get a good set of owners together. You never kno what a mass of similar thinking people could accomplish!
Plus, i'm going to start posting some cool guide on how to further customize / enhance your device! Good stuff to kno.

This tutorial was create for THE G2. I would NOT recommend you trying this method. Go around and search google for a tutorial MADE FOR YOUR PHONE. Although the phones are almost exactly alike, they don't necessarily mean they are exactly the same.
Find a different method.

Need help
This is not working for me. I temprooted my phone using visionary but when i try to use terminal to permroot, whenever i type "su" it say permission denied. Please help. I've been trying to do this all night and have been unsuccessful.

Hmm...It is true that it is out of date but for me it works fine. I didn't use the wiki way cause it was to confusing for me and Unfrogivens method was working fine on me. Not saying this method is better or anything and I know this method is unsafe "if" you do not fallow what it says. Like always people try Gfree method 1st before trying this one...(Only for G2)

Hello
Hello all totally new to android and was trying to root my g2. I followed instructions thourghly ( so i thought at least) and the s is still on after i exit the emulator and reboot. The last part about typing sync threw me off, how many times am i supposed to type sync while hitting enter after each line? Which lines, im sure overanaylzing something but didnt seem to work and tried multiple times. Thanks for your time..

[Q]All of my G2 Root/Unroot Questions

[Extremely Nooby Questions Below]
So, I looked through the forums and didn't find anything that applied to the G2, or told me what I needed to know, so I need some help. This is my first Android
device and I like it so far.
My first question is about the "VISIONary" App. I installed this about a week ago and along with it I installed "Titanium Backup", "Shoot Me", and "SuperUser" just showed up somehow. I've been seeing many people say that "VISIONary" isn't too reliable. So, if I want to try out, the RAGE version of the temp/permaroot do I need to uninstall all of these apps? Or Just Visionary?
Also, to uninstall visionary, so I need to press the "UnRoot" button, and then uninstall, or can I just uninstall.
I also thought that, "adb" was the same thing as rooting. According to the Wiki , they aren't. So I need to do both to successfully root the G2?
Is "OverClocking" a completely different thing too?
What do I have to look out for while trying to root my phone? Any precautions to not brick my phone.
Also, I found a really good youtube turorial - /watch?v=zdmtkHkrgLE - to Root, a Droid, are these the same instructions to rooting a G2?
Thanks in advance. Oh and by the way, I didn't know whether to put this in development, (Since it was about Rooting), Or Q&A, since it had questions in it.
If I need to move it, please tell me.

I'm not trying to be mean but these questions have been answered many many times before.
You need to read and read and read some some.
I would suggest you check the wiki and look in the dev forum. There is plenty of info you have to look for it.
Follow the directions for your specific device only

I'm no expert myself, just an average user who depends on the work of this awesome community to learn a little bit more about how these things work, so take whatever I say with a grain of salt.
I think all that matters for rooting purposes is removing VISIONary as the wiki states. As for how exactly to do this, not sure since I've never used it myself. Since it's just a temp root anyways, I'm pretty sure if you uninstall it and reboot at any time, it will be unrooted anyways. Titanium Backup will not even work without root, so you might as well remove it too (although not sure if you have to). I'm not sure what Shoot Me is. If you're in doubt, removing it before you root and reinstalling might help, but I doubt it's necessary.
The rooting instructions for the G2 are very specific. Do NOT use the same instructions for the Droid from that youtube video. I'd only recommend following instructions specific for the G2 you find on this site. This right here is definitely the best way I know to do it:
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_G2
I'd had some experience playing around with rooting my G1, but I never needed to deal with adb and was also initially confused. It's basically a shell that you can use to communicate with your phone when its plugged in via usb to your pc, using a command prompt or terminal or something. The instructions for setting it up aren't 100% clear from the wiki, but this guide was amazingly helpful in learning how to set it up in Windows:
http://forum.xda-developers.com/showthread.php?t=865685
Once you have that running, following the recommended rooting method from the wiki (rage/gfree) is seriously a breeze. Just follow it carefully and you won't brick your phone. The devs have really simplified the process for us in a short period of time.
This was also a really helpful FAQ that pretty much answered all my initial questions when it came to rooting, if you read through all of this carefully, you'll be able to figure it out pretty quickly:
http://forum.xda-developers.com/showthread.php?t=835777
Also, if you plan on installing a custom rom like cyanogenmod (highly recommended), you may want to back up your copy of swype cuz you'll lose the swype keyboard when you do it. Here are some good instructions on how to keep that:
http://forum.cyanogenmod.com/topic/10225-how-to-keep-swype/
Overclocking is a completely different game. Once rooted, you can use an app like SetCPU to speed up the clock speed on your phone's processor (stock is 800 MHz). I've seen some people able to achieve speeds of 1.9 GHz or so, but what's more common is around 1.4 GHz if i'm not mistaken. Obviously, for the increased, performance, you'll take a hit in battery life and such, you probably dont want to push your phone's cpu too far if its not necessary. Rooting gives you the option though.
Lastly, if you want to unroot, there are more complicated methods posted if you use the older rooting method which is currently not recommended. For this method, you can basically follow the instructions in this post:

The PC10IMG.zip can be found in the original post of that thread. The instructions for turning S-on via gfree are also found in the wiki.
I know that's a lot, but hopefully it will answer a lot of your questions.

Small corection to the post up. Am not expert but I just did.
Set cpu will allow U slow down to 245 Your cpu or go 806. To go more then stock speed U have to flash new kernel and this metod is permanent overclock with will keep settings after reboot phone. Second metod is easy way using scripts. U can find scripts on xda. This will give U 1400.
Don't forget to setup profiles on SetCpu with save U Battery

[Q] CAN SOMEONE PLEASE HELP ME UNDERSTAND ROOTING G2 - First Phone -

Hello I am new to this whole (Mod ) thing and until I bought a Pre Modded G2x I never new it even existed. The first ability to change how your screen transitions got me hooked completely ! I am posting this for the simple fact of Not Understanding
I have viewed several ways to Mod the G2 but none I could understand and I fear Bricking my phone which would not please me the slightest. I was stuck when I read
ABD
Most of the other terms i got. Is there anyone here willing to Chat via Skype or Email IM to help me Root this and eventually install a nice MOD onto my PHone, or simply put How to mod the G2 in - Noob -
Ps. I really like Cyanogen if you want to tell me what you think about that MOD i would be more than happy to Listen
I would GREATLY appreciate it and THANKS !

For chat go here http://webchat.freenode.net/ then for channels type G2ROOT
There will be plenty of people who can assist you during the root process.
ADB = Android Debug Bridge. It's comprised of your phone (that has Settings > Applications > Development > USB debugging enabled) connected to a PC that has the Android SDK (software developers kit) installed. It's just a link between your PC and your phone that allows you to do some manual commands (unless you use terminal emulator on the phone) that we can use to gain root access. Once your phone is connected you can type adb <command> from a command prompt (eg start > run > cmd.exe)

Try using the guide I posted. So far a lot of people have managed to get their phones rooted using it and I tried to make it as simple as possible.
Link here =)

The guide in the wiki is very straight forward and is the safest means to root as it was developed by the devs who actually found the means to root the device. The only way you can screw anything up is if you mistype something so please, please double check your typing.

The Links/Guides stickied thread has tons of valuable info, as does the Wiki:

Your best bet is to read up, and understand as much as you can. If there is something you don't understand, run a search on this forum's search function. If you REALLY can't find it, after legitimate attempts to use the search function, then come on here and ask. This is how most of us figured out how to mod our phones when we first started. As hinted at in the video in post #3 above, there are thousands of users here, and lots of newcomers trying to figure out how to root their phones. If those in the know spent their time leading people by the hand over Skype, they wouldn't have time for anything else. People have already spent lots of time writing guides, so put them to good use.

UPDATE
So yesterday after 5 long hours someone was willing to Completely walk me through which really helped. I understand the basics to rooting a phone now. The net question is a few. I need help deciding the Mod I will use. I messed with Cyanogen before but heard many good things of others. What are a few Favorites, or recommendations. And how would I go about installing it so I dont lost the android market. Also if I want to take off a Mod how would I go about doing that

First off, download ROM Manager from the Market and, once installed, use it to flash ClockworkMod Recovery. Once that is done, use it to make a backup of your existing ROM.
ROM Manager has many great ROMs listed and you can read reviews of them and flash them via the app. The sticky in the dev forum has a list of many other downloadable ROMs, many of which aren't already listed in ROM Manager.
To go back to the ROM you're on, just restore the backup you made.
