Trying to root an original EVO; unable to boot into recovery - Android Software/Hacking General [Developers Only]

At my sister's today, and she asked me to root her EVO as mine is. In trying to boot into recovery, when I attempt to do so, I get to the white screen, select recovery, but then the red triangle with red exclamation point within it shows on the screen. The only way out of this is to do a battery pull and try again, but the same problem recurs every time.
Is there something I'm not doing correctly?

Just an update...
In playing around with this a little more, I got this message:
E: Can't open /cache/recovery/command
Click to expand...
Click to collapse
At the top of the screen the options are:
Reboot system now
Apply update from SD card
Wipe data/factory reset
Wipe cache partition

That thread will answer your question. Post #3 has an explanation of the image. You need to flash a recovery (.IMG) file from the bootloader. Hope that helps.
Good luck

^^Exactly^^
Simple issue. You just havent loaded clockwork or Amen Ra properly. If its a brand new evo hit unrevoked.com up. Download the program. Hit the button and wait. It roots and flashes clockwork for you.
Easy..

[Q] Problem mounting Superuser.zip on Nexus S

Hi All:
I followed the instructions at theunlockr.com:
http://theunlockr.com/2010/12/17/how-to-root-the-samsung-nexus-s
to root the Nexus S. I made it up to step V., section 5. When I enter fastboot and select "Recovery", I end up with a little Android guy with a white triange over his head and an orange exclamation mark inside, and I can't move past that, so I just have to pull the battery and reboot the phone. Why am I not getting to the stage where I can select a Mount System?
Any help appreciated - thanks!

Nevermind, I got it. Phone is now rooted!
(mods, feel free to delete this thread, sorry for the waste of space!)
Could let me know how you got pass the little triangle please? I'm still stuck there.

That is the stock recovery image. Flash the CWM recovery appropriate for your device via fastboot, then boot into recovery, mount /system and flash the su binary.
Once you've done this boot the device and remove/rename /etc/install-recovery.sh. This will prevent the device from restoring the stock recovery upon reboot.
Or, if you need to flash something with the stock recovery, hold Vol Up and press power again while at the triangle screen. This had me stymied for a while. Stock recovery does a signature check so it's not useful for much. Can't flash superuser.zip with it.

Bootloader Unlocked... now what?

Hey Everyone,
Im sorry in advance if I'm about to ask the dumbest questions of the day/week, but I'm brand new to this, and I haven't found any answers in any of these threads, so go easy...
Up until now I customized the heck out of my mt4g. Tonight however, I followed HTC's instructions and unlock the boot loader -- as I thought based on what their site said, that I'd be able to flash custom roms to the phone once unlocked.
I was successful in unlocking the Bootloader, but (S=on) still exists. I'm kinda stuck now because I don't know what to do next? Is it possible to go from here to Root, if so, how? I've tried the HTC Super Tool for over an hour and it's not working... not giving me perm S=off. Maybe I'm doing something wrong?
If the phone isn't rooted, then how am I supposed to be able to flash a rom??... Do I do it from the HBOOT menu? Because I can't seem to do that either. If I opt for "recovery" while in HBOOT, I come to a red triangle, and have to do a battery pull.
The stock rom that's loaded now has GB 2.3.4 running.
My goal is simply to get CyanogenMod running on this phone. I just don't know what the next step is. I've already factory reset the phone so all my customizations and apps are gone therefore I don't really care what I have to do to get where I want to go. If it's possible to root from here, what's the next step? If root isn't possible, then how do I flash a new rom, like HTC claims I can do now that the BL is unlocked??
If someone could offer some help, I would be super appreciative!!

Follow that guide and get off the official HTC unlock. You should have read the thread on this forum about it.
Sent from my mytouch 4g using xda premium
okay... I followed the guide and I achieved "perm-root", I believe.
If I go into terminal emulator, and type SU, I get a # returned. I do notice however that when I boot into HBOOT, it still says s=on. Not sure what the difference is between 'perm root' and 's=on' but...
I have rom manager downloaded. I also have titanium backup downloaded and did a full backup.
PROBLEM:
In rom manager, I Flashed ClockworkMod Recovery, and then downloaded the nightly CyanogenMod, no problem, but every time the phone reboots (into recovery mode), I stop at the red triangle?!?!?!
What's going wrong?
Open rom manager and art the top is an option to install recovery-install it, then you should be good to go
I did install recovery. Everytime it reboots into recovery i get the red triangle.
After I get the red triangle, and I hold the Vol Up button and hit power, I come to a BLUE recovery menu (3e) with 4 options:
- Reboot system now
- Apply update from sdcard
- Wipe data/factory reset
- Wipe cache partition
in the middle of the screen, in yellow text it says "E:Can't open /cache/recovery/command"

If you had your device s-off and rooted, why HTC unlock? You just went backwards.
i started with HTC Unlock, then achieved perm-root, but (s=on)
Recovery
Hello,
I had the same issue, I had to flash the recovery with adb
1) If you dont already have it download flash_image and place it in your adb tools folder
2) Download the recovery you need and unzip, then rename to recovery.img and place in the root of your sdcard
3) open terminal and use the following commands
adb push flash_image /system/bin
adb shell
su
cd /system/bin
chmod 777 flash_image*
flash_image recovery /sdcard/recovery.img
4)wait for it to finish
5) type exit
adb reboot recovery
this should solve the issue
You can find the recovery here...including the new touchscreen version
http://clockworkmod.com/rommanager
You can download flash_image here
http://forum.xda-developers.com/showthread.php?t=902493
Thanks to Raichison for all the above
okay #furydude39, im all ready to run through your steps... when i issued the first command "adb push flash_image /system/bin", the handset responded with
"failed to copy 'flash_image' to '/system/bin/flash_image': Read-only file system"
Any idea where to go now? This is obviously why every time i boot into recovery that the processes initiated by RomManager isn't sticking.
an hour later...
I was able to execute the commands correctly that 'furydude39' recommended, and still nothing.
Here's a video I shot of the phone [still] giving me a headache

Have you turned off fastboot?
Sent from my HTC Glacier using xda premium
yes, just checked... fastboot is off
We need to find out why it is not flashing the cw recovery. Are you able to to mount /system partition and copy files to it? I'm thinking a downgrade might be necessary so you can do gfree and eng bootloader.

okay guys...
I got past the last problem, of getting clockwork mod recovery to work. So, that's all set.
NOW, I use rom manager and i downloaded cyanogenmod 7.1 (stable) + google apps. Once the downloads were complete, I checked all three boxes... backup, clear caches, clear dalvik cache. The phone reboots, goes right into clockwork mod recovery.
the backup goes fine... the cyanogen flash goes without error, and then the google apps flashes without error.
NOW, the phone reboots, and the thing just hangs on the White t-mobile boot screen. Is this supposed to take a while before it goes into Cyanogen's screen? It's been sitting on this white screen for at least 5 minutes.

You should manually wipe and flash. Doing it from the app seems to screw up some of the time. Make sure you wipe system data cache and dalvik before flash. It even helps to reboot recovery after doing wipe before you flash a rom.

In recovery, using the volume rockers, look for factory data reset/wipe. I'm not to positive on the exact names, since I have touch recovery. When you find it select wipe data an wipe cache. after those are wiped, go back then find advance, wipe dalvik cache. When that finished, go back. Select install from sdcard, find your files an install them. Everything should work then.
If I helped, give thanks, if you please.

Thanks all for your suggestions. I finally was able to get Cyanogen to stick. Had to wind up flashing the boot.img manually using fastboot via Windows while in HBOOT screen.

Red exclamation mark coming out of android mans chest when trying to go to recovery

Has anyone else had this issue? I have loaded the CWM recovery, with success according the the message i get after loading it. I try to boot into recovery to flash my SU zip, and when i hold down the volume buttons and power to boot into recovery, i get a little android man with a red caution sign coming out of his chest. I did do some sort of Motorola OTA update before i loaded this recovery, wasnt sure if that was affecting it. Anyhow, it lets me go into recovery if I keep pressing buttons, but then when i try to run my SU zip, it says signature verification failed, and when in recovery, it doesnt say anything about it being CWM recovery. Any help is appreciated!
edit: When i am in recovery, at the very top, it says Android System recovery <3e>
does that mean my recovery didnt load properly?
Well I did a factory data reset, then flashed my recovery again and the custom recovery loaded and I was able to do the SU zip update. So I am guessing this means that the update is somehow messing with recovery loading? Thought this might be something good for you developers to know.
Assuming you're using the stuff from shabby's post that was put up not long after the phone was released, I've not yet seen anyone say that this still works after performing the Moto update.
Moved as this is not development therefore doesn't belong in the development forums.
Thanks
AvRS
OP, it sounds like you didn't flash CWM correctly the first time...
The behavior you describe is the stock recovery.

The problem is that either the CWM recovery didn't take, or it did but when you updated, it reverted to stock recovery. I don't know which as I'm not familiar with the OTA you are referring to
Either way, you can try flashing CWM again and see if it takes
Sent from my PG06100 using xda premium
I installed the latest OTA update to my reverted back to stock, but still unlocked Q. CWM recovery and SuperSU worked on first try.
It sounds to me that CWM just didn't take. I remember reading something saying that the photon q will re-install the default recovery upon boot. It took a couple tries but I think what worked for me was flashing it through fastboot, then immediately rebooting into the recovery without ever letting the system boot up. After that it went right into CWM and has since gone there everytime.

Installing CWR - Not working

Hi All,
I've looked all around for the answer to this and am thoroughly lost. I have the Verizon Galaxy S3 with VRALHE. I rooted it, then used EZ-Unlock 1.2 to unlock the phone, then installed Rom manager and flashed CWR. It says it installed 6.0.1.2 but when I try and go into recovery it only goes into Android Recovery. If I flash CWR and right away click the boot into CWR button it seems to go but after that it will only go into Android Recover both via Rom manager and holding Volume Up, Power and Home. Anyone know whats going on?
Thanks for your help!
If it does go into cwm the first time then after that stock there are two files you need to erase that basically reinstall the stock recovery on reboot. I can't recall them, but you could probably search here and find them. Or the easier way is busy flash a custom ROM n that first boot into cwm. By the way ez recovery is better for installing our recoveries, give it a shot.... It may sick without the extra stuff I just told you.

Anyone know where to look into about the files that need to be deleted? I'm not finding much. EZ recovery worked the first reboot but returned to Android recovery after a reboot.

I would recommend re-flashing Clockworkmod Recovery from EZ recovery, then using EZ recovery to boot into Clockworkmod Recovery, after your are in Clockworkmod Recovery select the "Reboot system" option, you should then be asked if you want to erase two files to make Clockworkmod Recovery stick permanently (At least until you flash a different recovery) select the "Yes" option, then after it has completed that task the phone should reboot, while it is rebooting boot into recovery and you should find that Clockworkmod Recovery is still installed.
I like to help, but Google stuff. This is what you would have found as the second result
/system/recovery-from-boot.p*
/system/etc/install-recovery.sh
Sent from my SCH-I535 using xda app-developers app
So to confirm to everyone, Deleting the 2 files above does work! So delete the files then re-flash CWR and restart that's it!
I wanted to thank everyone for the help!

What rooting guide did you follow? Did you flash Clockworkmod Recovery yet? If you can provide me with this information I can try help you further. If you haven't flashed Clockworkmod Recovery yet then you will be presented with the normal stock Android recovery system that you described.

Ummm... You do not necessarily go into recovery to root it. Have you installed and used Odin through your PC? You say you are trying to root your phone, so before you get ahead of yourself trying to flash recoveries I recommend reading up a little bit, it is very important you follow directions specifically or you will brick your device....
http://forum.xda-developers.com/showthread.php?t=2046439
There is even a video watch it while you root your phone, and pause along with it.
If you have already done some of this, and done any of it wrong there are steps to recover through Odin.

[Q] Inspire 4G Need help flashing rom with S-ON

Hello, I've recently completed the Bootloader unlocking method with Easy Ace Root Tool. Bootloader is unlocked and SHIP S-ON, I need to flash a rom. These roms require S-OFF and have no method to flash them with only an unlocked bootloader and S-ON.
So let me get this straight, us 'low level' and unexperienced users are left without any method to gain S-OFF privileges without following the vague guide provided at tau(dot)shadowchild(dot)nl/attn1/?p=411 Yeah... I can't.
Trying to find alternate methods I have only gone in circles and keep running into old how-to guides. The more I read the more confused I become. I hope someone can point me in the right direction, I would really appreciate it!
Thanks,
Ninjewbag
You don't need S-Off. Flash a ROM in recovery, then flash the ROM zip's boot.img in fastboot.

Good deal, thanks for the reply!
I put the ROM Android Revolution HD 9.0 on the root of my SD card, booted in recovery mode and chose the recovery option, I got the red exclamation mark icon so I pressed VOL up + power button which didn't work so I pulled the battery. I tried all above steps again but this time I was able to successfully get into "Android system recovery <3e> with VOL up + power button. With 4 options:
Reboot system now
Apply update from sdcard
wipe data/factory reset
wipe cache partition
I chose the option to wipe all data, said it could not find Efolder name)'s and "data wipe completed successfully".
Then I wiped cache, then chose the option to apply update from sdcard, it said "Invalid operation" then "success rebooting by reason 00" and proceeded to reboot by itself.
Phone factory reset, I rebooted into recovery again with the same red exclamation mark error. Pressed Vol up + power and back into "Android system recovery". At the bottom in yellow text it says "E: Can't open /cache/recovery/command". I tried another "update from SD card" and recieved error: "success rebooting by reason 00" and reboots.
I don't have a nandroid backup as I read I needed Root to make one, but the phone still works fine as far as I can tell. I don't have a working simcard in it though.
Also from what I've read my eMMC chip may be fried so it looks like I'm retiring early. I'll keep an eye on this thread among others with the same problems.

You can install the app and then open the app and use it to manually download the recovery zip which you can flash or copy it to your pc and extract the recovery.img file and flash with fastboot. It's a good idea to familiarize yourself wiht the adb and fastboot utils as they come in handy.
