White triangle with yellow exclamation point (!). battery pull?

tried to boot in to recovery and got a screen with a white triangle and a yellow exclamation point inside above an android robot.
the suggestion is to battery pull. anyone else have this issue? if so, what's the procedure on reboot?
thanks.

I think that's the Stock Recovery Menu ( i kept getting it when i was trying to install the Patches from Fresh & used Clockwork Recovery because the two weren't compatible ).
Do you definitely have a Custom Recovery installed?

You pressed the power button instead of the optical trackpad when trying to reboot from custom recovery

Optical trackpad? What Evo has one of those? LMAO!

Flash Clockwork recovery or AmonRa recovery. You have stock (no recovery).

It is hard to answer your question without further specifics.
For example:
1.) Are you rooted?
a.) If yes, what are you trying to boot into recovery for? - flash radio/wimax or rom???
b.) If no, go to Android Development and read how to Root and install a custom recovery.
2.) If you have a custom recovery, what is it?
to put it simpler than this.
1. What ROM do you have?
2. What custom recovery do you have?
3. What step did you do to get into recovery? - from android or from boot up?
*If you pull a battery while trying to flash a radio, you might have the coolest looking paper weight in your part of the town

Hello shawnathan9!
I have similar problem with my Nexus one.
I have a rooted phone (used superoneclick to root)
Installed clockworkmod and flashed it with the recovery image.
Since I wanted to install latest cynogenmod I used clockworkmod to install the latest radio for it. Now when the phone rebooted it is hung diplaying a white triangle with and exclamation mark inside it. I haven't removed my battery yet and have plugged it to a power source. Can you help me ?

You're rooted, but you are trying to access recovery, but you don't have one loaded. Search google for Amon_RA or clockwork recovery to flash. If you have rom manager, you should be able to flash either or and it should work.

I did the unrevolked 3 and got it rooted. Then I booted it up into the recovery mode and ran clockworkmod. Now how do I get a rom (like mikfroyo 4.5) on it? I tried booting and selecting a zip from my sd card(which mikfroyo 4.5 is on it in zip form still) But it would not finish/aborted ? What am I doing wrong? I have the sptint HTC EVO 4 g phone with all the latest hboot ect on it.

That is part of updating the radio. Just let it finish and it will reboot into recovery. The phone has to go to that screen to update the radio. You may be able to save it by booting into that screen and just let it sit there for a while...eat dinner...take a dump...do whatever and come back and see if your phone is in recovery. I would turn it off and charge it first to make sure you have enough battery to finish the update.

I have the same experience, when I updates to Gingerbread (OTA).

Hello thank you so much for your information. I will leave the phone in that mode (screen hung with triangle an exclamation mark inside + android green logo below) and plug in the charger, until tomorrow morning. Then I have a question if tomorrow the phone still hung in that screen mode, what I have to do?
If you can give me solution, I would be very thankful. Happening in August 23, 2011.

After 2 days, trying to download updates firmware (OTA) GingerBread on HTC Evo 4G, I failed because the phone has been rooted, I found a "superuser permision" app. in the the All apps menu.This meant it is a rooted android phone, which will not permitted to update firmware OTA, is this true? If yes, this is the cause of screen hung at triangle with exclamation inside, and android green logo below.

Fashed New Caulkins 2.0, and now phone won't boot

So, I flashed Caulks new EK02 Rom, and, when I went to restart, phone is stuck on boot screen; Wiped everything as normal before flashing, but stuck on the yellow triangle screen.
I tried all the normal stuff to get into recovery, but phone won't go past the initial boot screen.
I have a mac computer, and thats all there are in the house, so I can't use Odin..
Can someone help me get the phone back to a state where it starts up?
Thanks so much for your help!

Use heimdall.
Sent from the future.

did that, flashed to stock, and we are back in business!
I did think about the hammer though...
MOD, please close!

[Q] Stuck on Jelly Bean Boot Animation (red triangle problem)

I'm sorry I accidently had posted this question in the development forum. Mods please delete that thread.
Guys I need your help. I had 4.0.4 and then I unlocked and rooted my phone to get Jelly Bean (installed V1) following the walkthrough (the day it was released). Tonight I wanted to get to V3 so I made my backups (note not nandroid, just on Titanium & Go Backup) and tried to boot into Recovery Mode. Did the whole vol & power thing and got to the Fastboot mode. Selected Recovery Mode from the menu and was hoping to get to the screen where I can wipe and do the nandroid backup and all. But it shows the Google lock screen (unlocked icon) and then shows the android guy on its back, chest open and a red triangle. I remember having this a while ago when I was unlocking the phone and flashing JB on it but it was no problem. This time it just stays on this red triangle for a while and then the phone reboots (no menu for wipe, backup etc) but the kicker is that it stays stuck on the nexus jelly bean (the "x") animation forever and does not move from there. I've tried to wait it out for over 15 minutes and nothing. I can't even go back to stock on this as I'm using Wugs toolkit and the phone is not recognized in the list devices (I have Win8). I need to get this working as soon as possible. Any help is greatly appreciated.

Did you try ODIN back? I had this problem, but instead of the red triangle, I had the EXCLAMATION mark between a PC and phone icon. Somewhere along the line I messed up with the files and soft-bricked my phone. ODIN would be your last bet, but for me, nothing worked.
Got a replacement next day (covered by warranty)... Good luck, dude...

I met the same problem when I flash JB (JRN84D ROM) from 4.0.4. When I saw "red triangle", I just kept pressing power and press volume up and then it brought me to recovery page. However, be careful, after I did data wipe, I lost all of kernels, rom, cwm recovery...in my phone. it was my first time to flash a phone so I must have done something wrong so now I have 4.1 but re-locked and don't know how to root it again and get CWM back. But at least, you can try power and volume up when you see "red triangle" to enter recovery mode.

sueshake,
thanks for that handy tip with the power and vol up combo. At least now I have some access to phone...thanks
will keep u updated on the progress

You are welcome. Be careful if you want to do superwipe. I guess I almost bricked my phone by doing that. Fortunately, I did flash 4.1 stock rom successfully before wiping data, though I am not sure how I made it from 4.0.4.

Need help, Screen won't turn on =[

So while i was making a backup on twrp, and let it finish and rebooted back to the phone and nothing lit up but my buttons i felt the lockscreen circle and what , and was left stump on what to do so i dusted the old odin out and unrooted blindfolded into download mode and did the proper stuff into stock ICS for T989, and it showed for the stock bootanimation at first, so i was like cool, i'll let it sit and settle before i do anything and it stayed on the samsung sign for about 15 mins, so i did a battery pull and then back to square one on the same problem but now under stock, any ideas on how to bring the light back up, kinda bummed that ive had this phone since it came out and still survived me and i just got it new gear so any ideas could help thank you

the samething happened to me buddy. go to stock recovery and wipe data and cache. and you will be fine.

just fully unrooted and sent it back since i had insurance

I had a similar issue last night.. turned out to be CWM screwing up.. reflashed to the newest cwm and everything worked again

[Q] Sprint EVO 4G I'm in over my head

I've tried searching, but there are so many "variances" in my situ. I figure I'll never find a complete answer.
Contract is up, so I would like to get it back to unrooted, stock with stock recovery.
Background
I got the EVO 4G in December, 2010, I honestly do not recall whether I used Unrevoked or Revolutionary to root it. I thought it was Unrevoked, but found a Revolutionary folder on the PC, it's had ROM manager and CWM since the beginning.
In the two years I've had it, I tried a few ROMs. The last one started getting buggy last month, so I installed a rooted stock rom 2.2.
I installed a stock unrooted ROM 5.07.651.1, then flashed stock - recovery.img.
HBOOT 2.10.0001 S-OFF
After that was all complete, everything looked good...
I did vol down - power and got the red triangle & exclamation point.
The next day I simply turned the phone on and got the red triangle & exclamation point.
Did a battery pull, waited 5 mins same thing.
Waited an hour, battery back in and powered up fine, except I ran Root Checker and it still had root.
I reinstalled ROM Manager and CWM to be able to look at things closer.
Now, I get the red triangle & exclamation point intermittently on boot-up and everytime I try to do a recovery after vol down - power press or through ROM Manager's "Reboot into Recovery" option.
At this point, I'm in over my head, I don't want to brick it, so I'm looking to more experienced folks for help.
Thanks In Advance,

Can you boot into CWM, or is that when you get the red triangle? Sounds like you need to reinstall your recovery. I (and many others) prefer an Amon Ra-based recovery, like Smelkus, over CWM on my OG EVO. Do a search for it here on XDA.
Sent using my HTC EVO LTE and a magic wand

I got the red triangle (as expected) doing vol down & power on. Did not expect it after volume up and power on, CWM would not load either.
The issue was something was corrupted.
I did an RUU with an older version of a stock ROM and recovery, now all is well.
Thanks,
