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.

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] stupid family...stuck on htc boot screen

OK so I need some serious help. I'm not a total n00b but I'm still fairly new to the rooting world.
I recently rooted my dinc and installed the new cyanmogen 7 to bring it to gingerbread. I had let my sister use my updated phone because she has a dinc too and was considering doing the same.
She was messing around with it and downloaded something from the marketplace and when she ran it the entire phone shut off. I don't know what she installed and when asked she doesn't know either. When I boot the phone it stays at the htc boot screen and will not go any further. I've tried a recovery which all the forum topics tell me to do and unfortunately it doesn't give me the option to load anything from my sd card. The only menu options under recovery are: Bootloader, reboot, reboot bootloader and power down.
When I plug my phone in my Windows 7 comp it isn't found as a drive and only shows up under device manager. If it makes a difference I rooted using unrevoked3. I'm not sure what I can do at this point. Please keep in mind that although I'm not 100% new at this I'm still really unfamiliar with it all.
What can I do to get my phone working properly again? I don't care if its from a factory reset I just need to get it working.
Thanks!

The white screen with your device info is not the recovery menu, it's the Bootloader/HBOOT menu. Select Bootloader from that menu and you will be given an option to reboot into recovery, most likely ClockworkMod Recovery. Once there you should be able to restore from a backup or reinstall Cyanogen 7.0.
If you cannot boot into recovery download the latest OTA update here. Rename it to "PB31IMG.zip" and put it on your SDcard. Reboot into the bootloader and it will detect the PB31IMG update and press Volume Up to apply it.
You'll need to root your phone again after this, though.

thank you!!
it worked perfectly...thanks!!!!!!!!

Glad to hear it!

[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
Sorry if I incorrectly used some of the terms in this post.

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.

GNexus is Soft Bricked and Data is Deleted from internal Storage when reboot

So here is a little back history.
I just recently purchased a GNexus from Sprint
Unlocking Bootloader and flashing Twrp went Great.
Backing up original stock rom went great!
My First Issue
My problem started when I flashed a JB rom. I notice that the phone was taking extremely long to boat up. Stuck at JB Boot Screen for about 45mins. I immediately thought that okay. .maybe im missing some type of requirement or twrp needs to be updated. So I battery pulled my phone.Attempted to go back into recovery and restore my old stock backup. WIth that being said i found that TWRP is corrupted. I did another battery pull and tried once more (same results)
I did another battery pull and booted to the bootloader when I selected recovery this time a screen popped up that allowed you to a factory reset (It was not the original TWRP Screen) My idiotic mistake was that I choose yes which then deleted my nand backup. As you now see I have a nexus that does not have a rom installed
I have been able to successfully adb push twrp back to my phone and TWRP comes up when I boot into recovery.
Here comes my second issue.
When I adb push a rom to the sdcard it transfer fine. I have been told to reboot recovery when you adb push a file to it. Therefore I reboot the phone and boot back into recovery to find out that the rom is gone. I have even tried to just directly flash the rom when I transfer the rom to the phone via adb push. TWRP states that the rom installed successfully so i reboot and the phone is still at a softbrick stage where I just have the google logo and the unlock bootloader at the bottom. When I boot back into recovery the rom.zip is no where to be found.
I have tried recovering by using ODIN and successfully followed each step for the GNEXUS CDMA\LTE version. Once again upon reboot I still receive the google bootloop of death.
Can anyone help me get my phone back to normal I will truly appreciate. I don't believe I truly bricked my phone because of that fact that I can still boot into bootloader, recovery and ODIN mode.
Specs of my phone: (From Bootloader Screen)
Product Name - tuna
Variant - toro 23GB
HW Version - 14
Bootloader Version - PRIMELD02
Baseband Version - L700.FD02 CDMA - L700.FD02
Carrier info - None
Serial Number - (Do I have to list this?)
Signing - Production
Lock State - Unlock
Once again any help is truly appreciated. I only had this phone for one day.. lol only made 2 calls on it before I screwed it up :laugh: (On stock rom)

After you ODIN stock it will bootloop. You don't have a custom recovery anymore, but if you remove the battery and then do "powers and both volume keys and select recovery" In recovery you will see a android with a red X. Press "power and both volume keys again" This time you have android system recovery that's in blue. Choose "wipe data/factory reset" and "wipe cache partition" . Then "reboot system now" after all that's done. You phone will boot up to factory in 3-5 min.
Reread everything you said... First thing first get back on stock. I used Odin method. Then follow steps above as it will bootloop.

ok, i will try this.
Thanks
After trying what you stated above i was able to successfully return to stock.
Thanks again for your help.. It's funny how something so small can lead to hours of debugging and searching for the answers.

Hey look on the bright side....you won't make the same mistake again!
I made the mistake of flashing the Touch CWM last week and accidentally wiped my SD instead of System as I was trying to flash a new rom with a full wipe....I wasn't impressed!
So now I'm back to the non touch screen recovery which I'm used to and harder to make a mistake on.

Is my M8 bricked?

Hi XDA-Fellows
1) thanks for all the help of this community so far
2) my problem: I had my HTC One M8 rooted, installed TWRP (I think in the end I had 2.7.8.0 as last version) and Cyanogenmod with a nightly build of around 18. March 2016 installed! THEN the big mistake happened. In advanced developers menu of cyanogenmod I activated the option that was called something like "on update of system also replace recovery software". That obviously was stupid.
Upon rebooting normally TWRP launched and installed the latest nightly. This time I see the white screen with HTC logo on it, red text in bottom, top part of the screen shows "ENTERING RECOVERY", 3 seconds later I see a black screen and every like 2 or 3 seconds it looks like the screen gets powered, it flashes darkgrey shortly (again, looks like it gets powered but instantly shuts off immediately).
This just can be stopped by pressing either P+U or P+D for like 10 seconds. Then again, white screen with HTC logo and ENTERING RECOVERY and the screen switch on/off-loop.
Is my device bricked? What can I do now?
Any help is appreciated.

Hi,
Can you enter to your bootloader ? So maybe you can just reflash it to see if it's going to work..

Yes I can enter bootloader. How should I go on from here on?

Well you just need to download the new TWRP from their web site https://dl.twrp.me/m8/ after that you put your device into bootloader and you plug your phone into your computer and download a toolkit from xda like htc one m8 toolkit and you follow the instructions..

Thanks. I will give it a try and give feedback.

It worked. I could enter bootloader, switched to FASTBOOT mode, installed ADB Drivers for windows and replaced recovery with latest TWRP! THanks a lot for your help! I thought I could throw away my M8

Well. It worked not completely. I was able to reboot my phone into the Cyanogenmod. But upon entering recovery mode (which I expected now to be TWRP) I get the same result again ... Screen off/on within seconds, repeating endlessly

I think you need to reflash the boot.img and the ROM completely. Because i don't know why do you have a black screen.

I activated root access for apps and tried ROM Manager first! It failed, then I used flashify which worked. Automatically downloaded latest TWRP (3.0.0.1) and flashed it, reboot into recovery. Everything works like a charm again! Thanks again for your help!
