[EVO 4G Android Development] Killasquad:
I am new here please help me out....I have couple of questions please bare with me.I successfully complete this entire tutorial but what happens to all my downloaded apps?I think in the tutorial i backed it up but how do i restore/install them??

What exactly is NAND unlock??

will system update (firmware/profile/PRL/HTC software) remove root?
[EVO 4G Android Development] rvasquez1989:
Make sure you installed the HTC Sync/drivers for your HTC device. Otherwise, you phone will not be recognized. Drivers are included in HTC sync. Just follow the instructions and what it tells you to download and you will be golden:D

I thought i would ask here since this is the guide i used for root. My phone just received software update 1.32.651.6 which i believe is for the sdcard.. Now, im pretty sure someone has a way around it already since i think it will break root. So i decided to try and install it, but it wont install for me. I end up in recovery, and get a status 7 error when trying to install... Last time i read up on that, it looked like someone said it had to do with the boot partition if im not mistaken... but anyway, if someone gets a chance to look at this post, any help will be appreciated. thanks! :)

[EVO 4G Android Development] TheBiles:
Don't install any updates OTA. Just download a ROM based on the OTA update and flash it.

-------------
[EVO 4G Android Development] f1n3st:
i'm having trouble with instruction #55 when i reboot the phone and go into the bootloader it doesnt detect the PC36IMG.zip i see that it checks it but it doesnt come up with a yes or no option to flash,

i've done everything correct up until this point. the only thing i have doubts on is instruction #53 i did as you said and copy and pasted the 4 lines (one line at a time) what it did was this

adb shell

#cat /sdcard/flash_image > /data/flash_image

cat /sdcard/flash_image > /data/flash_image

#chmod 755 /data/flash_image

chmod 755 /data/flash_image

#/data/flash_image misc /sdcard/mtd-eng.img

/data/flash_image misc /sdcard/mtd-eng.img

#

was it supposed to do this? you said it was supposed to repeat itself which it did.

i then figured it might be a corrupt file so i tried to open the PC36IMG from instruction #46 which is the last PC36IMG [the debug] and it didn't open, it said the file was corrupt. am i not supposed to be able to open this? if i am, then i think theres a problem with the file. the file i have is 990 bytes, is this correct?
[EVO 4G Android Development] shawnten:
after about 5 hours of work I have completed everything. this was an intense tutorial. Hit a couple of snags along the way but it is done. At least I think it is. How do I know for sure if I am nand unlocked
[EVO 4G Android Development] Joshnor713:
I had this exact problem. I found out that the PC36IMG.zip file I downloaded was not complete. The full file is about 170mb and for some reason the one I had was only 120mb, I guess the download stopped at some point and I didn't notice. So I re-downloaded the file and made sure it was the correct size and then followed those steps and it worked.

It was driving me crazy for a while there until I found out what was wrong
[EVO 4G Android Development] daddysal:
Do I havta do steps 12 & 13 before I flash a new ROM or does it save the Apps automatically?
[EVO 4G Android Development] TheBiles:
You don't have to backup your apps unless you are wiping data / factory resetting, but you should usually do that when flashing a new ROM so...
[EVO 4G Android Development] daddysal:
Thanks, now if I'm gonna flash a new ROM do I erase the old one 1st?
[EVO 4G Android Development] TheBiles:
You should wipe data and the dalvik cache. Other than that, the new install will wipe all of your system stuff.
[EVO 4G Android Development] daddysal:
Great, thanks for you advice.
[EVO 4G Android Development] f1n3st:
yea i figured that was the problem, but the weird thing is, i tried to redownload the file and it seems like it only downloads 960 bytes and it stops it doesnt keep going i tried 3 different browsers, IE8, FF, & Chrome for FF and Chrome it downloaded as a .zip but for IE8 it downloaded as an html link, i'm right clicking and selecting save target/file as but it doesnt seem to want to downloaded correctly,

i'm going crazy!!!

EDIT: I found a new link for the eng-pc36img i'm not sure if i can post it here but if you need it PM me.
[EVO 4G Android Development] kpoz:
Please bear with me if this has been asked before, but I don't have the time to go through all 59 pages of this thread.

I am apparently a real rookie when it comes to this stuff. After what step can I stop and use my phone? Can I unplug and use my phone after Step 24? Do I have to flash a radio update if I use the rooted version of the stock ROM?

How long does this whole process take?

Also, do I need to complete Section V if all I want to do is root my phone? It isn't very clear.
[EVO 4G Android Development] boomhower:
Just start from the beginning and go step by step. It is really very clear, just follow along. It takes a while to do because you have to wait for various installs and reboots of your phone.
[EVO 4G Android Development] kpoz:
Ok. It looks like I stop at Step 35. Do I need to flash the radio update if I choose the rooted version of the stock ROM? Also, what about Section V of the tutorial? Is that only needed for NAND unlocking?

Also, approximately how long will it take? 30 minutes? An hour? I'm asking because I need to leave (work) in an hour haha.
[EVO 4G Android Development] kpoz:
Also, what does it mean to flash a recovery as opposed to a ROM?
[EVO 4G Android Development] kpoz:
I have a 30 minute train ride ahead of me. I'll attempt to read as much of the thread as I can and see if I can answer my own questions.

If anyone has the answer, however, feel free to post it :)
[EVO 4G Android Development] TheBiles:
Don't flash the radio update yet if you plan on unlocking NAND. Do it at the very end. The NAND unlock took me about 15-20 minutes my first time, but I'm pretty experienced with Android. I would leave at least an hour for a new user who might hit some bumps along the way.

ROMs are the operating system that you use. During normal use, everything you do is based on the ROM. The recovery image is a special partition that allows you to flash new ROMs/updates/kernels as well as backup and restore your current ROM.
[EVO 4G Android Development] kpoz:
First off, thank you very much for answering my questions. It is all a bit clearer. Do I need to unlock NAND? What are the benefits? All I would really like to do is root my phone for the purpose of using Joeykrim's custom ROM builder, which I can use to remove the garbage Sprint and HTC dumped on this phone: http://www.joeyconway.me/evo/custom/index.php

This leads me to a new question. Can I install the above ROM on top of the ROM in Step 30 of your tutorial?
[EVO 4G Android Development] RyboCollier:
Hello,

I'm stuck at step 46, when I go to download the PC36IMG.zip debug ROM it takes me to a site that is under construction. Is there an alternative place for me to download the file?
[EVO 4G Android Development] TheBiles:
More and more custom ROMs are requiring NAND to be unlocked. It is also handy to have a custom recovery flashed right to the device instead of relying on a hacked update.zip on your SD. Also, some programs like ROM Manager and Root Explorer (very handy, by the way) require full NAND permission.
[EVO 4G Android Development] nonpointtruth:
I keep getting this error after step 56.. Any ideas why?

As you can see, I tried several times with no success..
[EVO 4G Android Development] nuformzdesign:
thanks for breaking this whole process down into simple steps. It was a huge help to me.
[EVO 4G Android Development] Bukem75:
Thank you for the guide... Yet another n00b has been helped!

I got through the guide fine (after using the eng-PC36IMG.zip included with SimpleRoot2, since this thread's link seems to be dead) and I installed the radio 1.39.00.05.31 as well.

Any ETA to getting 4G back? I go from Turning on... to Scanning... to Connecting to Sprint... to Disconnected... all in 10 seconds or less. I used to get 2-3 bars of 4G all the time.
[EVO 4G Android Development] TheBiles:
Which ROM are you using? It should be working on most custom ROMs.

-------------
[EVO 4G Android Development] Bukem75:
I did not install a custom ROM after your instructions. Once I finished, I updated the radio.

radio is 1.39.00.05.31

Kernel 2.6.29-ac94cf60

htc-kernel@and18-2 #1

Build 1.17.651.1 CL160858 test-keys

Software 1.17.651.1

I been a winmo guy for years. Still trying to catch up =)

EDIT: I did use the eng-PC36IMG.zip from SimpleRoot.1 cause your link did not work.
[EVO 4G Android Development] TheBiles:
Are you still using the debug ROM or are you on a stock rooted ROM? 4G doesn't work on the stock rooted ROM. You should get a custom ROM.
[EVO 4G Android Development] jeffreynichols:
Please update the tut with a new eng-PC36IMG.zip URL, that corrupted file has cost me hours trying to overcome.
[EVO 4G Android Development] horiveira:
I'm having the same problems as these guys, can someone either pm me or post a link with the second PC36IMG.zip?

I'm stuck and I don't want to half ass the job!

EDIT: Found a way to get to it by extracting it from the huge file from the program provided in the SimpleRoot thread

roadblock@ #55... no opt. to flash image

1st off, THANKS to every one posting info here esp. the OP!

Everything's been going well so far but I hit a roadblock at Step #55 where I should "select yes to flash the image"

I do not get that option on the phone... when I boot back up into recovery, it pauses, does a little dance and then settles on the screen with the options <FASTBOOT> <RECOVERY> <CLEAR STORAGE> <SIMLOCK> <HBOOT USB>...... I never get the option to say yes to flash the image.

So... I'm doing trying to do this on my Mac (osx 10.6) so nothing was different up until the shell script part in step #51... I ran the "recovery-mac.sh" not the windows .bat one... it appeared to work.

in adb when I run adb devices it shows me there's a device connected... I don't exactly recognize the name, but when I unplug the phone, it goes away, so I assume it's the phone and I've got usb connectivity. I did not have to install any usb drivers...(and I couldn't find any to install)

I tried everything both from my adb that I installed with my Android sdk *and* with the adb-mac that came in the EVO-recovery package... both appear to yield the same results.

when I do the adb stuff in step #53, I enter each line and get no errors *however* I do not get the lines repeated back to me as indicated in the tutorial and by other posters...

SO... my question... am I doing anything wrong that you can tell? Any one experienced with doing this on a Mac recognize what's going on here? Is the lack of getting the commands in step #53 repeated back a warning sign?

I have yet to try using any different files, as some have posted problems with corrupt files... I'll try that next, just wanted to put up a post first to see if any red flags pop up.

THANKS!!! (let me know if any other info would be helpful in answering my questions)
[EVO 4G Android Development] horiveira:
Thanks a lot. I successfully rooted the phone, despite a few bumps.
[EVO 4G Android Development] ozolins:
Updates for EVO root Tutorial

Just a couple thoughts to possibly update in your excellent tutorial:

1. when I download the file in step #47 it's now called "recovery-RA-evo-v1.7.0.1.img"

2. I'd suggest turning off the "hide known file extensions" option in windows for purposes of creating this tutorial... and suggesting to users of the tutorial to show the whole file name as well. Just thought that might be the best way to avoid file name confusions here...

I prefer to see the whole file name in my, any way.
[EVO 4G Android Development] ozolins:
Thinks I got it.... used the other PC36IMG.zip mentioned in this thread ...from the file used in the SimpleRoot thread. Guess OSX wasn't telling me the file was currupt... I ran the whole process through again on a windows machine, it said the file was corrupt, I got the other file and the whole thing worked... with WinXP.... Didn't try it with Mac, but everything seemed the same, so...

Also, it seems like installing Android SDK is unnecessary because that zip with the scripts in it, includes ADB...

Error after step 50

Hi, thanks for a well documented tutorial. I can't get past step 50. After I enter adb reboot recovery I can't execute any adb shell commands, I get the error:

exec '/system/bin/sh' failed: No such file or directory (2)

Any ideas on how to debug?

Thanks,

Tim
[EVO 4G Android Development] ibejaminben:
problems

So i flashed with clockworks method and I am trying to unlock nand I run the first reboot command and get to the triangle exclamation point screen but nothing happens when I run the recovery batch any ideas
[EVO 4G Android Development] EyeMN3:
just want to post and say thanks. I read over a lot of information last night and decided that flashing DamageControl was in my best interest. took me awhile, but using this guide got me through it.

just want to note that some of the links in the first post are no longer valid. specifically, the SECOND PC36IMG.zip file - it's only 1KB. I got kinda frustrated trying to flash that image because the bootloader wouldn't recognize it and would just kick me to the normal menu. took me awhile to find out I was looking for a 170MB zip file, not a 1KB file, hahahaha. once I figured that out and moved it to the root, I had zero trouble.

i am a total smartphone/android noob and this is my first phone and first root. i still have some concerns about battery life and my radio, but I guess that's for another forum.

thanks for the help!!!!

[EVO 4G Android Development] crzycrkr:
Stupid question, but can I remove two different PC36IMG.zip images and the update. zip from the phone after making a NAND backup?
[EVO 4G Android Development] guesswhatimevan:
Awesome tut, but can't get past step 46 because the link is down.
[EVO 4G Android Development] visions6699:
ive done the update.zip rename and put it in the SD card and nothing happens... it still says the same thing ;/
[EVO 4G Android Development] TheBiles:
No, the latest OTA can be rooted. I'm not exactly sure what is causing that. You are in recovery, correct?

No, this is 100% real root. I just use unrEVOked to backup with Titanium Backup in case anyone wants to use it.
[EVO 4G Android Development] visions6699:
ok ok! i got it to work!
[EVO 4G Android Development] itzjonjon69:
yeah i hold vol down and press the power button and when that comes up i scroll down to recovery and launch that, then launch update.zip and it brings me into the custom recovery and thats where i try to flash it, but still no luck! :(
[EVO 4G Android Development] TheBiles:
Re: [TUTORIAL] IDIOT-PROOF Root Guide! No ADB, no fuss!

Ok, from the custom recovery you do not want to "apply sdcard: update.zip." You want to make sure that you're selecting "install zip from sdcard" then navigating to the proper zipped ROM file.

I will definitely get actual screens of recovery mode uploaded tomorrow.

-------------
[EVO 4G Android Development] itzjonjon69:
i do, do that but same thing! maybe i wasn't meant to be rooted :(
[EVO 4G Android Development] eck0728:
What did you do? I'm having the same exact error
[EVO 4G Android Development] JvIo55iBl3r:
i m complete root rookie who just had my first android phone, evo4g, like a week ago(of course). I have did a few thread study here about root. thank you so much for such vivid instruction.

Biles, I do have a question for you now about ROM Manager. I mean i didn't see any adb command in your instruction, or even any command in the shell. do i understand correctly that ROM Manager is alternative for "evorecovery" mentioned in the toastch instruction?

Sorry about such basic question, thank you for your patience and time.

Great instructions OP - this would have saved me some time last night, as I am a n00b! I did coax it into working nevertheless, using Toast's steps and a handful of other forums to help me understand why ADB wasn't working. Good stuff, either way!

I think Toast's instructions are good for people who want to explore more.. I certainly do.. And now, thanks to toast, I've learned a bit more about things like recovery, nand backups and restores, and abd...
[EVO 4G Android Development] eck0728:
Ok i figured it out for us having the read problems. The problem is we updated to .6 and we don't have root so the Clockworkmod never really installed. I fixed this by redownloading Unrevoked root, then follow the clockwork instructions, reset my phone and it works perfectly.
[EVO 4G Android Development] watzone69:
Nicely done my friend! You are a good tutorialist (if that's a real word).
[EVO 4G Android Development] Breakthecycle2:
This is weird, I renamed the rooted rom to update and update.zip (I'm on Windows 7) and it will not flash. I keep getting an installation aborted error message. Any ideas?
[EVO 4G Android Development] eck0728:
The problem is we updated to .6 and we don't have root so the Clockworkmod never really installed. I fixed this by redownloading Unrevoked root, then follow the clockwork instructions, reset my phone and it works perfectly.
[EVO 4G Android Development] Breakthecycle2:
Hmmm...so instead of flashing through recovery, flash through the clockwork mod?
[EVO 4G Android Development] eck0728:
No, we still use recovery, but the update.zip never fully installed becasue we didn't have full root even though we used Toasts root method (because we went to .6) Basically this is step 25B (for us with .6). Right before you use Clockworkmod simply use unrevoked to root and then continue, and all will work 100% i just used it 30 seconds ago
[EVO 4G Android Development] Breakthecycle2:
Awesome, I'll finish this up tomorrow. Thanks for your help!
[EVO 4G Android Development] eck0728:
Anytime bro, OP you should add this in as 25b, and ^ whenever you finish plz confirm this works so others may use this. (it worked on my evo flawless)

I found this link in another thread online and used it. It looks to be the same and I have gotten all through this tutorial using it.

w w w.sendspace.com/file/kky7wu

Can't post links yet. On a side not, can anyone answer my question above? Do the two PC36IMG files and the update file need to stay on the phone after completing this process and doing a NAND backup?

Thanks
[EVO 4G Android Development] TheBiles:
Thanks for that! I was looking for a mirror. The first post has been updated.
[EVO 4G Android Development] crzycrkr:
Updates?

I'm sure it's already been answered in here, but it takes some time going through this many pages. The ROM is the older version. Can we do the regular updates and keep root, or do I need to flash a newer ROM?

Thanks
[EVO 4G Android Development] feeth:
I too am getting the no space left on device error at step 56.

I have went back to step 53 as instructed and no luck.

I have read thru the last 5 pages and unless I missed something, I am at a loss.

Any tips?
[EVO 4G Android Development] neckface:
You have bad blocks in your NAND. Try this.

I was given this error when I tried it that way.

So I unrooted then rooted again and it seemed to have solved the bad block error. Here's a guide on how to unroot. http://theunlockr.com/2010/06/14/how-to-unroot-the-htc-evo/

I also followed this tutorial and am wondering what files (if any) need to stay on the SD card afterwards.I installed rom manager and am now running fresh 0.3.
[EVO 4G Android Development] RickBaller:
I'm trying to "Create ROM Backup" from ROM Manager before I try and start NAND unlock and things and when I try and do this the phone reboots into a screen with an EVO icon and green progress bar along the bottom that goes about halfway, stops, and I get a EVO icon with a big red question mark above it.

So I'm freaking out a little here, did everything to the t except for switching the stock rom for the damageless rom.

Thanks a lot first root ever and it went flawlessly!
[EVO 4G Android Development] TheBiles:
You completed the NAND unlock, right? If so you can delete everything off your SD card because you have your custom recovery right on your phone. I suggest getting ROM Manager (because it will make your life so much easier) and flashing a ROM like DamageControl (or Fresh Evo .5.x when it comes out to the public in a couple days.
