recovery boot issues - red triangle, then reboot

I'm having issues getting recovery to work on a Verizon version xoom. I first flashed CWM version 4.0.0.4. The first time I tried to boot into it, it was stuck on the android with the red triangle for a long time before finally getting into it (coincidentally when I was hitting the volume key, don't know if that's related). Anyway, since then I haven't been able to get into it. It will be suck on the red triangle screen for a minute or two before rebooting into the stock rom (I'm running stock ICS). Since then, I've tried flashing the new TWRP 2.2.2 or whatever version it is and it has no effect. It's still doing the same thing. Any clue what's wrong?

So what I'm reading is suggesting that the android guy I'm seeing is the stock recovery. I'm not sure how that's happening. I'm installing the recovery using fastboot on my PC and being in the bootloader on my xoom. The prompts on both appear to confirm success.

I haven't tried this yet as I'm at work, but I think I've got the issue sorted. The following is what appears to be happening from what I've read.
1. I've still got the custom recovery stalled. When the Android guy pops up, one needs to press volume up to enter the options. Otherwise, it reboots.
2. The recovery flashes are taking because I'm booting back into the rom after a flash. The system's built in recovery protection is re-flashing the original recovery at that point.
3. To make my CWM/TWRP/whatever flash stick, I'll need to power down and then boot directly into the recovery.
I'll post again tonight to say if this works. Hopefully this thread can help out others who have the same issue.

[Q] SOLVED Problem flashing CyanogenMod 9.1.0 Stable

I rooted my MT4GS a few months ago but stuck with the stock ROM. I decided I wanted to try out the CyanogenMod 9.1 ICS ROM. I followed the following steps:
1) Installed ROM Manager.
2) ROM Manager indicated a newer version of ClockworkMod Recovery and I installed it (5.0.2.7).
3) Using ROM Manager, did a full backup of the current ROM. All went well.
4) Using ROM Manager, downloaded and installed CyanogenMod 9.1.0 stable-doubleshot. I specified to wipe the data and cache partitions. The installation seemed to go normally.
When the phone rebooted, it was stuck at the logo screen. Had to remove the battery to turn it off. Tried a couple times, still the same.
Since I had the backup, I decided I would use CWM to restore the old ROM.
When I boot into recovery mode, it shows CWM 5.0.2.7, but whatever option I try to choose from the recovery menu, The screen just goes blank with the CWM logo in the middle and nothing else happens. Hitting the power button returns me to the menu, but no option works, even power down or reboot. It just goes back to the CWM logo again and I have to remove the battery to shut it down.
So, I thought I would try using fastboot to flash the ROM again. When I boot the phone into the boot loader and select fastboot, then plug the phone in via USB, nothing happens. Windows does not see the phone and ADB or fastboot don't see it either. It's not a driver issue, as the computer is still setup from when the computer was rooted and I connect the phone all the time with no problems.
When the phone is off and plugged into USB or the charger, I still get the charging light, though it goes off after about 10 seconds, then comes back on and cycles like that.
Is there anything I can try at this point, or is my phone bricked? It seems like I followed all the steps correctly. Is there an update.zip I can put in the root folder and see if it picks it up?
Any help would be appreciated.

Ok, after rebooting Windows, I was able to get the USB connection to the phone to work in fastboot. It seems I missed the step described in this thread:
http://forum.xda-developers.com/showthread.php?t=1508556
which states with S-ON you must flash the boot.img separately. I did that via fastboot and the phone boots into cyanogenmod now.
However, I still seem to have the issue with clockwordmod recovery. As long as I do the recovery functions from rom manager, everything is fine, but when I manually boot into the recovery menu, I get the same behavior of any choice from the menu just blanks the screen except for the CWM logo and nothing happens. I tried reflashing the recovery image using fastboot, but still no go.

This is solved also. Seems on the MT4GS, the trackball is the selection button. The power button appears to only be a back button.

What a thread! Two nicely phrased problem definitions, two well explained solutions, and all from the same guy. Sorry we weren't able to help directly, but you obviously found the answers you needed elsewhere in the forum. And you updated the title as well to show it was solved. Thanks.

[Q] Can't get to recovery after (successful) upgrade to KK.

Hi,
just got time to update my 2nd XT925 to KK (RSD'd back from CM11 JBBL to stock SFR rom, let the phone find its update and apply it, everything went fine).
But whatever KK recovery I try to flash, it gives me an exclamation mark and nothing else (I'm unlocked, yes).
Don't know what's happening here. Can someone helps please ?

Are you saying you are trying to flash a recovery or are you trying to GET to the stock recovery? If you are trying to get to the stock recovery, the key presses to get to it have changed.
Your best bet is to power off your phone. Then, press and hold power+vol up for a few seconds until you see the menu come up. Then, press vol down to highlight Recovery and then press the vol up button.
Eventually, you'll see the "Dead Andy". From there, press and hold vol down+vol up+power. You might have to do it a couple of times. Eventually, you'll be in the recovery but for the XT926, it's kind of hard to read because for some reason, they decided to make it dim.

No (but thanks anyway). What I tried to was only to install a KK recovery for CM11.
I successed but I had 2 problems mixed: the 1st one was that the Linux version of fastboot (or mfastboot) did'nt work with the new bootloader. Both were complaining about "(bootloader) Variable not supported! ". Had to find some old laptop with Windows installed to use it to flash the recovery without error.
But even then if I just let the phone reboot, I would'nt get the new recovery (just the stock one after the keypress you speak about). I had to go straight from bootloader screen to the recovery (by manually rebooting) to get it work. Looks like the standard boot just restored the stock recovery each time I tried.
Thanks anyway, it's working now.

Variable not supported comes up under some Windows, but it usually still works.
You never go straight to the bootloader when you reboot. You have to reboot the phone (or turn it off first) and then press and hold vol up+power. Then, from there, you use vol down to select recovery and then press vol up.
It never boots directly into the recovery unless you tell it to via an ADB command or from within a custom ROM that allows it.

Keep in mind, the stock recovery will override the custom recovery if you don't immediately boot back into recovery. Flash recovery, when that's done, press power to shutdown, and use the method Bolski described to boot into recovery.

Let me see if i undestood.
You say that if you don't boot right into recovery, the stock one will overwrite CWM/TWRP. So i understand that, after very reboot you must reflash recovery if you want to use it again.
Or am I missing something?

It won't reflash every time. You only need to boot straight into recovery the first time, so that the update binary completes. After the first time, you'll be good.

I think this may be the problem I am having. I cant get my 926 to boot to recovery from fastboot after I load CWM recovery. Is there some trick?

I need help with this tablet - few questions

Background:
I attempted to root the device. so I installed CWM... Well it doesnt stick. once you boot it never stays. When I go into recovery mode from the boot loader it says "no command" But if I flash it and then reboot right into the bootloader then go into recovery it works fine.
First issue: CWM doesnt stick
which led me to another issue..
ADB doesnt work in CWM (which I thought). So I decided to flash PhilZ recovery and found it didnt work there either! So I figured it had to be my drivers - but they worked fine in Windows and when the device is booted normally in the OS. (I am using Nvidia latest drivers)
Then I figured let me restore the unit back to the original image (i signed up as a developer) downloaded the Nvidia 1.2 Image and reflashed everything using fastboot (system, boot, recovery, data, etc.)
Since I had never tried to go into the stock recovery maybe it was CWM or PhilZ...
Leads to my next issue:
The stock recovery doesnt work no matter how many times I flash it. When I go into the bootloader and click on recovery mode I get "no command" with the andorid guy dead.
1. How can I get back the stock recovery using Nvidia's image. The recovery is not working
2. How can I get CWM to stick?
3. Why isnt ADB working in recovery mode but working fine when booted in the device?

All has been fixed except for #2. Cant get CWM to stick... but for 1 and 3:
OK.. got the stock recovery - I didnt actually know you had to do volume up when at the "no command" screen..
and also I figured out how to fix the driver issue...
For anyone else having the issue you need to uninstall the driver until it shows up as Shield with the exclamation. You must be in the recovery in an area like sideload.. (Not in android OS)
Then Update Driver, Browser and then click on "Let Me Pick from a list on my computer"... find Android then select "Android Composite ADB Interface".
Now the driver works in ADB and in the OS

Same Problem
I'm having the same problem with CWM reverting to stock recovery after system boot. I didn't see your post until after I posted my own thread -- I probably should have titled it specifically about the stock recovery reversion so others will find it. Anyway, not that there's at least one other person besides me having this problem, I'm less worried that it's just me being stupid. Although that's always a possibility. Maybe someone will come along and help.

Recovery Reversion Problem Solved
Okay, I solved my recovery reversion problem -- I wasn't using either a custom boot.img or the Beta SuperSu (currently BETA-SuperSU-v2.42.zip), one of which is needed to keep root on Lollipop. (Apparently I knew this a month ago when I first went to 5.0.)

After rooting my nexus 5 is not booting up with non stop booting animation

I have a nexus 5 16 GB and i downloaded the recent software update android 6.0.1 and then I decided to root and I used 'Nexus root toolkit v2.06' and first unlocked the bootloader and then rooted. Everything worked fine but after the process was complete it was rebooting and the booting animation went on and on for many hours and the device did not root. I really don't know what's going on. My purpose is to install a custom rom: cyanogenmod 12. Now what should I do ???? PLEASE HELP. When i try to enter recovery mode it shows a picture of the android mascot with opened back and exclamation and cannot enter command as well. and after some time the booting animation begins and goes on and on...
please help...

Unless something has changed, version 6. requires that you flash a special kernel before you can root your phone otherwise you are as you are now, stuck in a boot loop. You should probably download the factory image from Google, and then flash the system image to get rid of what you have done.. Perhaps then your phone will start normally

Thank you very much for the reply, I really do have no idea as to how to flash the factory image because i am very new in this area. Could you please recommend software and which factory image i should download, please ?? thanks very much.
:good:

Also, you mentioned a 'special kernel' what does that mean. All i want to do to my device is install cyanogenmod 12 and for that i believe it needs to be rooted, so i am really confused. What should I do know

I'm having this same problem, and unfortunately, when I start the phone on fastboot, I can not access the recovery mode in order to upload a factory image of nexus 5.
I used the new tool available her for quick flash, and now, I don't have a phone.

First, don't panic. Your phone is still very easy to recover. Unfortunately I can't get you a complete walkthrough here (for now at least), so I'll give you the main idea and you'll have to do your homework (as maybe you should have done before).
1. You need to get fastboot working on your computer. It's included in the Android sdk package, but there might be some easier way to get it. Google it. You might need drivers for your pc too. Google it as well.
2. Then you need to get into fastboot mode on your phone. To do it, hold down power button AND volume down button until it gets into fastboot mode. You will see an android on his back with the cover open. At this point, connect your phone to your pc, open a terminal on your pc and type "fastboot devices" without the quotes "". It should find your phone if fastboot is working. If it doesn't work go back to step 1.
3. Download TWRP recovery on your pc and place the img file in the same folder as your fastboot executable (not mandatory but easier). It can be found here https://dl.twrp.me/hammerhead/
4. Always in fastboot mode, type "fastboot flash recovery twrp-2.8.7.1-hammerhead.img" assuming you downloaded that file, which you should have by the way. It should install fine. If you haven't placed the file in the same directory as your fastboot executable, you will need to provide the path to your img file as well.
5. Then use the volume rocker to switch between modes and choose reboot recovery.
6. You should now be in TWRP recovery. At this point, download a custom kernel (anyone found on xda for hammerhead should do) and push it to your phone. It should be fairly simple with TWRP. Then flash your new kernel using install. It should help you get your phone booting normally. Alternatively, you can download a custom ROM like cm12.1 and flash it altogether. It will install everything needed for your phone to boot up too. Beware if flashing a ROM though, I strongly advice you to do a factory reset before flashing it. You will find that option in the wipe menu.
Hope it helps, let me know if you need further assistance.

Yesterday, I have tried everything to have my computer to recognize the "fastboot" command, and I installed like 2 or 3 different programs for that. With my old Windows 7, I have been able to push a flashed image to fix this issue, using the fastboot command, but with Windows 10, it's always telling me it's not a valid command. I'll keep trying it, otherwise, i'll have to "resurrect" my old Windows XP computer.
Also, I noticed now that, while trying to install the fastboot, as per some files that I could download, but no file has been copied into my computer, not even if I run it as admin.

fixed. but no RECOVERY mode options....
Hi Guys,
Thank you very much for the help, I have finally recovered the phone and running android 6.0 MRA58N but it is not rooted. Now if you don't mind could you teach me how to root because i have checked lots of videos and tuts but none worked for me...
IMPORTANT:
when i am in recovery mode why cannot I access options even when i press volume up + power button and release them at the same time...????
Thanks in advance.

Just flash a custom recovery via fastboot. Just make sure your bootloader is unlocked. Can't link though.

hi guys i have used nexus 5 mobile with cyanogenmod 14.1 .It worked properly in 1 year. after that suddenly switched off and it not properly boot up .i try to switch on my mobile , first it show google with unlock logo properly and when it show cyanogenmod logo it stuck and again show google with unlock logo....i try recovery mode to wipe and flash the same rom ....the process is interrupt at middle stage and again show the google..i try lots of time . after few try that process finished completely without interrupt. then use my mobile 1 day same as i used first time root. after that same problem occur on my mobile ..so help me guys
