[Q] Red Triangle, Dead Android - Nexus S Q&A, Help & Troubleshooting

After months of flashing everything in sight on my NS4g, the device appears to have rolled over and died! It started a few days ago, when it rebooted and asked me for a password to decrypt from storage (no password has ever been set). I couldn't get past that screen, so I decided to boot into recovery (TWRP), reinstall ROM (CM10) and gapps and restore data from backup.
No go. It just kept rebooting into recovery. But I was able to connect the phone to the PC and copy files from the phone but could not copy or delete files on the phone from the PC.
I used fastboot, Odin, and one-click-stock to wipe the device and install factory images, but the phone would boot no further than the red triangle-dead android.
Is my phone dead? I searched the forums and couldn't find any solutions other than to do what I have already done.

When you flashed to stock you erased your recovery.. Reconnect to your computer and push a recovery onto your phone and you're good to go..

Unfortunately, when I flashed TWRP and boot.img to the phone using fastboot and attempted to boot into recovery, bootloader reports "No Boot or Recovery Img."

Try the Nexus tool kit and from the bootloader (power and vol. up) select flash to stock (bricked) then in advanced boot temporary recovery to flash the recovery of your choice.. or push a boot image.

Wish I had better news but ... using the Nexus tool kit I was able to boot into TWRP but when trying to flash CM10 and gapps for this phone the flash failed; likewise, I could not flash CM10 and gapps by pushing the files from the PC to the phone. I first did flash to stock (bricked) but that brought me back to the red triangle, dead android.
I am beginning to suspect that the phone internal sdcard is corrupted ... is there a way to test for that?

When you got it to flash to stock did it boot up fully?
Remember that flashing to stock removes custom recoveries and you will need to flash one

No, the phone never did boot up fully. It got to the Google screen with the unlock icon and then to the red triangle, dead Android.

This happened when you tried stock or custom?..
Did it fully boot on stock image?..
The dead android usually shows up when you attempt to boot into recovery and you don't have one... If you try to boot and you loop back to the dead android it usually means you don't have a rom...
Try again to flash to stock, use the toolkit to boot a temporary recovery and flash a custom recovery.. Then make sure you are flashing the correct rom and correct gapps for that rom and for your phone.

I know have a recovery because the tool kit booted into TWRP; furthermore, the tool kit installed a TWRP 2.3 image (prior to installing the tool kit I was on 2.5 so the tool kit did something). From there, I tried to flash CM10 and gapps in the sdcard/download folder, but that failed, with TWRP returning message similar to "error opening ZIP".
I have used Odin to flash the stock image and it did not fully boot, ending at the dead android. Same results for flashing the stock image using fastboot with the phone connected to the PC. Same results with using the Nexus tool kit to flash a stock image (first JB and then, when that didn't boot, ICS). And, after the toolkit booted into temporary recovery (TWRP), I tried to flash (in this order) CM10 plus gapps, JB stock, and ICS, each time with the same results (no full boot, dead android).
I am with you when you say that the dead android means there is no rom, because my efforts to flash any rom, whether stock or custom, don't do anything. To all appearance, the phone contains a bootloader and a recovery and nothing else.
Thanks for your persistence ... any ideas for something else to try?

I'm at a loss.. Try again, maybe there's something missing.. And flash only one at a time and see if it worked (just ROM then reboot) then wipe d+c and flash gapps reboot then wipe flash... Ect... Ect...

I am too. Every method known to me (Odin, fastboot, adb) to flash a ROM, whether custom or stock, has failed to boot. Thanks for hanging with me on this; if you can think of solution I'll be glad to have it. Or if I solve it, I'll post here.

Unable to flash ROMs

Hi guys!
Yesterday I successfully rooted my NS (it is a European SLCD model with stock 2.3.6 on it) following the newest guide on nexusshacks.com. So I ended up with TWRP recovery.
Then I thought the easiest to install CM is via Rom Manager. Therefore I had to change recovery for CWM. (I flashed the latest one.)
And here comes my question: why am I unable to flash CM?
First I tried it in Rom Manager, after wiping everything and rebooting system nothing happens, except for a big yellow exclamation mark.
Then I downloaded the proper CM myself and I tried to do the whole process manually in recovery menu. After wiping and choosing update from SD card I get a message like the process is aborted.
I also tried with an older CWM and with other ROM.
Any suggestions?
Thanks a lot

Boot into bootloader, then flash recovery via fastboot.
fastboot flash recovery recovery.img
stock firmware will rewrite your recovery after each boot. flash recovery then flash this right after.
Follow what SEAN SAys..............He is a Master in all these , and he helped me with details to root, flash cwm, make it sticky and flash custom ROMS.
It took me 5 minutes to do all those , and Now I am switching Roms like I switch my underwears every day twice.
I must say, Sean has the best possible way which is like a finger click.

[Q] Phone Stuck in Boot Loop Why?

Hey All,
I just got my One XL and I was so excited by the root on 2.20 that I decided to try and flash the custom rom of AOKP on onto it.
After rooting the phone, I did the following:
Flashed TWRP 2.3.1.0 - success
Then I went and saw the thread about the AOKP rom and followed instructions. On that thread, it states that you must flash the boot.img before doing this through fastboot if you are coming forom 2.20 firmware, so I did that. Then I saw that it said on the thread "do not complain about bootlooping if you flashed a custom KERNEL or did not manually flash the stock KERNEL via fastboot" As this was the first custom rom I had attemped with this phone I assumed that I had the stock KERNEL already installed, so I did not flash any kind of kernel.
As soon as I flashed the boot.img from AOKP, I saw that there was red writing on the bootloader about this being for development use only and I noticed that the phone would get past the bootloader to a black screen and then would reboot (boot loop).
I thought that the issue here was that I did not flash the kernel so I went and downloaded the rohan.kernel and flashed that. HOWEVER, I did not realize that I was meant to use recovery to do that and I pushed the boot.img from within the kernel via fastboot instead of using recovery to flash the new kernel (not sure if that matters all that much, but I think that from now on all rom work will be done in the day time after sleeping a little more).
After doing that I see no change in the performance of the phone (it is still boot looping). I am unsure of what to do now. I managed to push the KERNEL zip file and the ROM zip file to the phone via adb but when I try and install them via TWRP I am getting an error because the phone reports that it is unable to mount /sdcard/.
Can one of the far more knowlegable gurus here point me in the right direction? I have wiped the cache and davlik cache numerous times but that has not helped. Should I use TWRP to wipe the system? How can I get the phone back to a place where I can install the new rom?
Thanks!!

First of all I think if you're on 2.2 fw I don't think you can flash kernels through TWRP - I think it has to be through fastboot, I don't know first hand as I'm still on an earlier fw version.
Secondly if you can get into recovery you can flash another rom.
Go to Mount > Mount USB Storage with your phone connected via USB, it should mount as a drive otherwise windows asks you to format format the drive if this happens chances are may have wiped it in bootloader with factory reset or clear storage in either case just format the drive.
You can then drag and drop another rom onto the phone and flash that - remember to extract the boot.img from the rom and flash via fastboot so it will boot.
Goodluck

Hey!
Thanks a ton for your reply! I managed to get the phone to install a new ROM (AOKP V5) and it seems to boot up. Now when I get into that rom, I see all kinds of things crashing on me. The "Settings" app crashes, the keyboard crashes..any idea?
Did you wipe system, factory reset, davlik and cache from within TWRP before flashing?
Try that otherwise if you're still running into issues post in the thread.
You flashed the 11/10 JB gapps?

ok, i got the phone back up now and have been able to flash stuff properly.
I am working on an issue where after flashing a new rom (AOKP v4) and then a new kernel right after (rohan.kernel V2) the rom seems to hang on the loading splash screen. Has anyone else had this happen? Know how to solve it?

[Q] Flashed new kernel, won't boot

I used Hasoon2000's HTC All-In-One Kit to root my phone. That all worked.
The issue came when i flashed a new kernel. I placed the boot.img from King Kang's new ROM (http://forum.xda-developers.com/showthread.php?t=1959099)
Anyway, When i boot I get the HTC, quietly brilliant logo, and this in red letters "This build is for development purposes only. Do not distrubute... "
i can boot into recovery (pwr+ vol down)
And i get the ***TAMPERED*** AND ***unlocked*** tags at the top
I don't know where to go from here...
Thanks for the help.
Also, whenever i boot into recovery or factory reset, neither succeed.
This was probably known info, just wanted to add it.

You mentioned in your original post that you could boot into recovery, so is that not working now? Factory reset might've fubared the recovery piece, so you could do one of two things:
1) download the original RUU version for your phone, relock your phone, and flash the RUU and start over.
2) try reinstalling TWRP.
This whole thing sounds like trying to install a kernel or fastboot flash a boot.img without SuperSU correctly installed. This is what happened to me when I first unlocked my phone and tried to fastboot flash the CM10 boot.img after failing the flash from recovery twice. Without that super-user permission, bad things tend to happen. If you decide to continue on with reinstalling TWRP, make sure SuperSU.zip is flashed successfully from
TWRP, then try your rom/kernel combination again (or even a different combination if you're apprehensive).
BEWARE: sometimes partially flashing these things can corrupt your sd card. I had to reflash the original RUU to fix my phone BEFORE I rerooted and flashed a rom/kernel.
Have you fastbooted a SU to your phone after you rooted and unlocked? I'd imagine you did if you followed the toolkit.. So your on 2.20... Just download cleanrom 5.1 on your computer. Mount sdcard via recovery and drag cleanrom onto phone. Flash entire rom in recovery. I bet it works
Once your on a stable rom, download king kang from your phone. Download flashgui. Open flashgui app, navigate to king kang and let it find the boot img and flash it for you.. Once successful, immediately boot into recovery and flash entire rom through twrp.
Success

Can't Access TWRP Recovery

Hi guys, I flashed the latest factory image, then flashed the latest TWRP but can access it 1 out of 10 tries.. What am I doing wrong? Is it a faulty replacement phone? Never had this issue with my other nexus 5 (same recovery file but lollipop and not marshmallow) and now I have this problem.. Tried to riflashato the factory image 5 times, boot to recovery without installing but nothing changed.. Thanks in advance!
If you just just flashed TWRP, then booted into Android, then reboot into recovery.. Android will overwrite TWRP with the stock recovery.

This is not really a fix, since to use Flashify one needs to be rooted already.
What I did to work around this was reflash LMY48M. After reflashing that, fastboot correctly boots/flashes twrp.
I've read that the issue arises when trying to boot and/or flash twrp with MRA56K installed, AND the device is connected to USB.
Ok, i got some of problems here, i tryied to root my Nexus 5 with other Android 6 version, it was the first one launched after development version. Now i have MRA58K version.
Problem 1 : I have no stock recovery, i first rooted original version of Marshmallow with CWM and i soft bricked, so no backup, no factory images. Installed MRA58K and there is no stock recovery, thanks god i can use bootloader. I can install TWRP, but i want to install the old recovery, Tell me how to do it.
Problem 2: Actual version of Marshmallow ask me to install a patch, but when installing i got stuck in TWRP, it cant install it (yes, android was rooted, but i installed twrp before root, and the update were before it.)
Thanks.
You can flash a stock ROM using the flash-all file in a command prompt. This will install stock ROM with stock recovery. Make sure the phone has an unlocked bootloader and you should be fine.
Official OTA updates cannot be installed with a custom recovery.
I tryied 3 times to install OS with flash-all. All the problems start after i installed CWM and try to root the phone, but after that, i used a stock rom image that was different build than actually one.
I`m not sure yet who`s fault is.
Any ideas?
I don't recommend using CWM, only TWRP.
After you flash TWRP always boot into it, and since you're flashing a custom recovery I'm going to assume you don't care about OTA's, swipe to allow system to be mounted. TWRP will automatically patch the system to survive android trying to overwrite it. Reboot into TWRP a second time to be safe. TWRP should stick from now on until you flash over it or restore stock system partition.
Yes, now i have TWRP as recovery, but i want to replace it with stock recovery.
Problem is, when i upload stock recovery and try to boot in recovery mode, i got the green dead android with red triangle.
But after TWRP uploading and booting in recovery mode, TWRP is there..
I really don`t know what`s wrong.
Flash stock recovery, select recovery from the fastboot menu, hold the power button and press volume up button.

Stock recovery corrupted. Red triangle. Android broken

Hello guys. I think I have a very particular problem since Noone on the forum has mentioned/solved this problem before. Basically I have my old tablet replaced with b01 battery. It came with lollipop os 2.2.2 (I think) I rooted it like I did before with flammable y01 with twrp so no problem on that hand.
Now I'm selling it and I need to get it back to the stock os with stock recovery. But as is seems this turns into something impossible :
Every time I try to flash stock image the red triangle appears when I try to boot into recovery no matter what I do :tried to flash Via fastboot many times, tried different fastboot drivers (one from Nvidia, another one from Google) tried to mess with flashing sequence - staging - reboot - boot.img - recovery.img - reboot - system. Img, userdata.img - dtb - oem lock - reboot and still the red triangle with broken Android. Tried flashing it from 2 different notebooks, with clean win 7 and clean installation of Nvidia drivers. Still no luck, as soon as I finish flashing staging and booting into recovery with volume keys I always get the red triangle. However when I try to install a twrp it boots into recovery instantly. I even tried erasing all partitions before flashing :fastboot erase recovery, erase boot system ecc without result, tried even to flash staging, boot and recovery partitions from older os versions keeping the system and userdata from 2.2.2 and no luck.. Can please some one explain why the original recovery doesn't want to stick?? The cwm recovery like twrp work like charm whenever I try to flash them... So it's not up to hardware.. Please help me guys
Maybe have to relock the bootloader. Why can't you sell it with a custom recovery and rom?

Stock recovery doesn't really have a user interface like TWRP or CWM so I wouldn't worry about the red triangle. Is there any reason you can't sell it with the custom recovery?
You can easily lock and unlock the bootloader so what's the issue with trying that? And if you want it to be 100% retail stock, the bootloader would be locked.
You can also try to re download the stock restore files again and try again. I don't recall the stock recovery giving you any options anyways so that screen you're getting should be fine.
