White triangle with yellow exclamation point (!). battery pull? - EVO 4G Q&A, Help & Troubleshooting

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?

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.

Thats what my phone is doing the clockworksmod menu will not come up only see the
white triangle with the exc symbal with the android symbal. have to pull the battery out ot reset but phone still loads up and works.

[Q] EVO will not load into recovery after root?

Hi all. First let me begin by saying I'm NOT new to rooting and I have a pretty good knowledge of what I'm doing.
Here is my problem. I WAS rooted before, and used Rom Manager/Clockwork to preform Nandroid backups etc.
I recently received a replacement EVO (cracked housing) and wanted to root again, which I have, with SU permissions and S-OFF using the latest version of unrEVOked. (this is after the December update to 3.70 with hboot 2.10) No problem with rooting, however when I want to do a nandriod back up, thru Rom Manager, (or alternative methods) I get stuck on the white EVO boot screen. I CAN NOT boot into recovery? Weird right?
EDIT: When I try to enter recovery in any fashion, it hangs on the white EVO screen...forever until I do a battery pull.
EDIT: Sorry, I CAN enter bootloader, however once there, I attempt to enter "recovery" and it bounces me back to the menu. This happens both via ROM Manager and the traditional way of "POWER" button and "Vol Down".
EDIT (again): Okay..I used Amon RA to preform a nandroid back up,(which worked) and now I'm stuck in a bootloop! Ugh! Trying to restore my Nanadroid backup using RA..hopefully that works and I can revert back to Clockwork.
Jesus...
Any help would be much appreciated!
Thanks!

Let me know what you do to fix it. I'm just going to put the 3.7 RUU on sd card and restore to default? Here is the link. Hopefully this works.
http://goo-inside.me/evo/stock/RUU/
I have the exact same problem!!!! I cannot boot into recovery! It throws me back to the main hboot screen. It freezes when I try to do a recovery and I need to return this stupid phone because it keeps freezing and re-starting on it's own and I've tried flashing the oem rom many times already. I have "s-off" and Sprint will know I've rooted the phone ... please help!!
I just get stuck with the evo screen but like all of you i can not get to recovery... any ideas
Do you guys have working ROMs on your phones and just can't get into recovery? Or can you not boot up at all?
Sent from my HTC EVO 4G with Tapatalk
Looks like your recovery didn't flash. Put this file on the root of your sdcard, boot into the bootloader and select yes to update, the reboot. This installs CWM 3.0+.
I'm in a similar situation after initially using Unrevoked, and I've tried flashing AmonRa and Clockwork from a PC36IMG.zip. Neither has gotten me a recovery screen.
Beyond that I can't seem to get a ROM to boot more than once. I can install ROMs with varying degrees of success, but invariably a reboot leads to the phone simply hanging at the white HTC EVO 4G screen. Flashing a new ROM generally works. Once. But then I'm constantly afraid of my phone rebooting for any reason, and I know it'll mean that I have to wipe the bastard and start all over again.
Any suggestions on the recovery issue? Perhaps fixing that will fix my reboot problems.

Try installing clean, wipe everything. With TB, backup the apps, ect. When you restore, restore only apps and data, not system settings.
Just to be sure I 'wipe everything' properly, which steps are you suggesting? Should I choose Clear Storage from the bootloader menu?
Just for clarification, I've tried to RUU several times and it has not fixed the issue.
I just used a modified HBOOT to allow me to erase my recovery, system, and userdata partitions via fastboot. After that, I flashed AmonRa 2.3 in Bootloader and it worked! I now have a working AmonRa recovery. I'm attempting to flash CM7 now, and I'll let you know if that works.
I can't take credit for thinking of this, I used someone else's guide, but I'll happily post the software and the steps if people are interested.
The fix was apparently temporary. The attempt to flash CM7 led to my Evo hanging at the white screen after rebooting.
The only way I've managed to boot into a ROM is pretty crazy... I flash the 3.70 RUU from a PC36IMG.zip version at bootloader, then I flash clockworkmod, then I flash SprintLover's ROM. If I flash in that sequence, I can get SprintLover's to work, but it will hang at the white evo 4g screen if I reboot. It's insane!
Anyone have any advice? This **** is bananas.

What I have done so far:
(the good):
#1 I used the "clear storage" from hboot and it works.
#2 I re-flashed "RUU_SuperSonic_S_Sprint_WWE_3.70.651.1_Radio_2.15.00.11.19_NV_1.90_release_161482_signed" from my PC via USB and this works too! It gets the phone back to factory settings wiping out everything and booting up normally.
(the bad):
#1 The phone still freezes and turns off sporadicly.
#2 I have lost root BUT the HBOOT screen still shows security is off (S-OFF) so still I cannot return the phone to Sprint!
(the ugly):
#1 From the "HBOOT" screen I choose "FASTBOOT" which takes me to the "FASTBOOT" menu, from there I choose "BOOTLOADER" and it throws me back to the "FASTBOOT" menu creating an endless loop.
#2 From the "HBOOT" menu I choose "RECOVERY" and it re-starts but it than freezes at the white HTC EVO 4G screen. I then have to take the battery out to re-boot the phone. Again another loop!
Any Ideas or any help would be GREATLY appreciated!

http://unrevoked.com/rootwiki/doku.php/public/forever Jump down to Q&A and download the S-ON tool. You need to load up a recovery image, CWM or amon_ra and flash that ^ then re-run the 3.70 RUU and you should be set.

[Q] major confusion

hi all, my wife has been running cm6.1 and lately it has had a few issues, so i go to download through rom manager, it fails downloading several times, download on a computer and transfer it over, boot into recovery through rom manager(i feel retarded for this one... no back up, didnt wipe) and install, well, it goes to the cm boot animation, sits for a long time, then i remember i didnt wipe so i attempt to get back into recovery and wipe, well, some how, the phone managed to go back to the stock recovery... needless to say i became very very confused...
does anyone have any insight?
thanks in advance
If you havent s-off, then you probably will see stock recovery and need to flash the update.zip to get to clockworkmod. I think i remember that right.
Sent from my T-Mobile myTouch 3G Slide using XDA App
i finally did get cm 7 up and running, and in rom manager it says that i have the latest availible clockwork recovery, but i can only get to it if i rebot to recovery through rom manager, if i go through the boot loader, it takes me to the black screen with the ! in the triangle, then after several button pushes takes me to stock recovery
This happens because ROM Manager reads the altered 'update.zip' from your SD card and it is recommended you use that program (app) to do all your loading and ROM stuff. Though if your phone is powered off you can hold Volume Down and power then after getting to the Triangle "!" screen pressing volume up and power gets you to altered 'update' screen.

[Q] Phone stuck on HTC screen and won't boot

Hi,
I rooted my phone about a year ago and recently wanted to update it and try a new ROM. Since I have no idea what the compatibility of of my old ROM I made a NAND backup then I reset it to the factory RUU version 3.29.651.5 and my phone was back to normal in the boot loader S was set as S-on.
I then proceeded to use the autoroot v2.5 in this thread: http://forum.xda-developers.com/showthread.php?t=838448. In the cmd prompt it said it was flashing the firmware, then said it was waiting for the device to boot up; however, the device did not boot up, I waited for approx 60 min and it was stuck on a black screen with the HTC logo in the middle and a small warning (triangle with exclamation point) in each corner. Now, it is permanently stuck on that screen. Even if I try to hold the volume down to get to the boot loader when it starts, it still goes to this screen.
What can I do to try to get out of this? I cant go back to my recovery to get my backup.
Thanks

The first time I tried to Root my phone, I had the same problem with Toasts Root method. That's stock Recovery you're seeing.
I ended up having to use Unrevoked Linux version and swore I would never unroot again, and I haven't.
I've tried using unrevoked and several other methods. The problem is I think most of them rely on the phone being on with USB debugging enabled. I unfortunately can't get there. The one ray of hope I have is that the device is recognized in my device manager as "Android USB device - HTC bootloader". Is there any other way I could fix this?

Are you holding power and volume down at the same time. Sounds like you are just holding volume. When you get to the bootloader I'd you see s-off all you will need to do is flash a PC36IMG of the recovery of your choice(I recommend twrp). Good luck!

Also, no need to unroot for any rom. Once you are rooted you can flash anything you want. Compatibility wise, you may need to update a radio but that is just flashed in recovery.

Thanks for the reply. Unfortunately I am holding power and volume down. Powering it on normally and powering it on while holding volume down both go to the same screen.

[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.

[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,
