[Q] I am stuck up with my bootloader - General Questions and Answers

I have rooted my nexus one and tried to flash a custom rom. I performed following steps:
1. Rooted as per the instruction. After applying the commands It was ready
2. Installed a custom recovery image with recovery-RA-nexus-v1.7.0.img and it was successful. After rebooting i went in to boot loader mode and took a nandroid backup.
3. Then downloaded a custom rom and placed all radio(radio-4.06.00.12_7), Google App(gapps-hdpi-FRF91-signed), CyanogenMod 6(update-cm-6.0.0-N1-RC2-signed) in to my root of the SD card.
4. Rebooted with recovery mode (holding volume down and power) and selected recovery and it rebooted but got a orange !(symbol) with android and nothing happens.
Please any one help me to how to resolve this. I tried once again installed a custom recovery with the same image. But no luck

Try to reflash CM or restore nandroid backup and then reflash CM

[Q] Red Triangle, Dead Android

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.

1. Are you rooted?
2. If so, are you installing it via TWRPManager app or fastboot?
3. Make sure update recovery is unchecked in developer options.
4. If all of these are good to go, I would recommend a clean flash, booting into Android, turn on adb reboot to bootloader, fastboot flash recovery enterimgfilehere. Root after this, and install TWRP manager app. Install the write patch. Make sure update recovery is unchecked in dev. options.
5. If all of this fails, download a toolkit (with correct drivers) and let it do the work for you.
Hope this helps.
How long have you had the device? If it is new, unlock the device.

Flash recovery not working!

Backstory: I tried to load Cyanogenmod on my phone; but first I had to load TWRP recovery in order to get to load it. This is where the issue came; I decided to go the easy route and attempted to install it through Flashify (an app on the Google Play store); upon restarting my phone; it was bricked. I went into EVERYTHING, when I tried to go into recovery it would just send me through the bootloop and then send me to AP Fastboot.
Confused, I called Motorola; and was notified and Flashify had removed my prevoius recovery and failed to but TWRP resulting in this.
Issue: So what I did is I got the CWM recovery specific for my phone (XT926) and went into ADB fastboot and typed "fastboot flash cwm.img", from my ADB folder of course. Then when I booted into recovery, nothing happened; it would just send me through the bootloop again. Please help.

Try another recovery / another version. Did the trick for me and you have nothing to lose
I have 2 XT925s. I bricked one to the point that I could boot to fastboot but could not even get into stock recovery. I was running stock 4.4.2.
I did the following.
I got the DROID_RAZR_HD_Utility_1.41. I used the TWRP 2.7.1.0 in that utility specifically for XT925.
I used fastboot to manually flash TWRP into the recovery partition.
DO NOT reboot past boot menu. Right after flashing, boot into recovery. That should give you TWRP.
I used TWRP to Install CM11 snapshot. I had to manually flash into the modem partition, the modem file also obtained from the above utility. You will need to flash in gapps for 4.4.2.
That recovered the bricked phone.
Of note, I was able to flash TWRP in the other phone. Backed it up. Transfered the backed up OEM ROM into the phone running CM. And get it to run stock ROM.
I now have one running CM11, and one running stock 4.4.2. I'm just comparing battery life. I've noticed CM11 has a smaller memory footprint than stock 4.4.2.
Cheers
did not work for me anywhere to be found stock 4.4.2 recovery img for 926?

persistent stock recovery

Hi,
I hope this question wasn't asked before, I couldn't find a solution to my problem yet.
I tried using the toolbox to flash Philz and later TWRP recovery. the phone booted normaly and not to the custom recovery.
When I tried to boot to custom recovery the stock recovery loaded instead.
I even tried the command prompt method.
Eventually I used the command m=prompt method and immediately manually booted to recovery and the custom recovery (Philz this time) loaded. I though I was done, but right after I set up the phone as I like it and wanted to make a backup of it, the stock recovery loaded instead of the custom recovery.
any ideas?
what as I doing wrong?
Thanks
Unlock bootloader amd ise the fastboot commands to flash tje recovery permanently. Guides in the general section.
I see I need to elaborate
I will tell you what I did step by step.
1. Using the toolbox (V6), I unlocked the bootloader, the phone booted as if it was just got out of the store (all my data was erased)
2. Entered the gmail account and basically went through the entire initial setup process.
3. Booted to fastboot again and flashed TWRP recovery (using the toolbox).
4. The phone automatically booted normally (not to custom recovery)
5. I tried booting to custom recovery and I got the stock recovery instead
6. Booted to fastboot again and flashed Philz recovery this time (using the toolbox).
7. The phone automatically booted normally (not to custom recovery)
8. I tried booting to custom recovery and I got the stock recovery instead
9. I opened command prompt and used the "fastboot flash recovery recovery.img" command, the recovery.img I got from the "philz_touch_6.59.2-bacon" zip file.
10. I immediately forced boot to recovery and got Philz
11. I set up my phone as I like it (app + settings)
12 tried booting to recovery again (from power off of course) and got the stock recovery again !!!!
Any ideas?
I tried again and partially succeeded
Hi,
I decided to do all using the command prompt.
This time I disabled the CM Recovery Protection (though I clearly remember doing so before but might have done it before unlocking the bootloader).
I tried flashing using "fastboot flash recovery" command TWRP recovery but when I tried booting to the recovery I got one vibration (the one supposed to be before the recovery loads) and after a few seconds (+1 logo on screen) I got another vibration and the system normally booted (not to recovery).
I did it again with Philz and it worked, I booted twice to recovery and it holds.
The only difference was that Philz recovery was named recovery.img and TWRP was named TWRP.img, I don;t think that matters.
I really wanted TWRP. don't know why it didn't work.
This question has been asked several times, see the FAQ thread:

Help, MMB29Q update wipes TWRP

Hi all,
Recently I updated my Nexus 5 from Lollipop to Marshmallow 6.0.1 (MMB29Q) - latest build.
everything stock works fine but, once I flash a customer recovery, in my case TWRP it stops working...I get either a startup loop or TWRP gets erased by stock recovery.
I tried various steps ...
flashed TWRP 2.8.7.1 - rebooted to boot loader was able to get into TWRP but, once I reboot system, everything works but TWRP is gone/erased and replaced by stock recovery?
Flash TWRP 2.8.7.1, then flash latest TWRP 3.0, reboot to boot loader and can get into TWRP but once i reboot into system, I am stuck on the initial boot loop.
I have to start from scratch of flashing system and boot etc to get past the loop and it still replaces TWRP with stock recovery.
I can always get into Fastboot but when I go to recovery it seems its being replaced by stock recovery.
anyone experiencing this issue? thanks for your help.
I guess I am doing something stupid but, not sure what...and thanks for your help
If you give more detail on the steps you are taking it will be easier for someone to help. Also, have you tried doing a factory reset when it bootloops?
thanks for the response..here are the details..
I had Lollipop with TWRP 2.8.7.1
yesterday, I downloaded latest build from android site...extracted all files....booted into bootloader and flashed all files..
rebooted - Marshmallow works perfectly...offcourse it not rooted yet or its locedback due to this flash
Scenario:1
So downloaded TWRP 2.8.7.1 and flashed it as recovery, no errors nothing...i rebooted to bootloader and went to recovery to confirm TWRP is there
I rebooted the system - TWRP gives option to root which I said yes so its rooted. I reboot system, this goes into bootloop - I wait for say 5-10 min in this loop mode and I see that adb can recognize the device but nothing else....its stuck in loop
when I force shut down by holding power button for few sec - and go back bootloader/recovery - TWRP is still there
***note*** I did factory wipe in TWRP but that did not fix above condition.
Scenario2:
exact same steps but after I flashed twrp2.8.7.1, I rebooted bootloader and flashed twrp 3.0 as well confirmed twrp 3.0 is flashed and rebooted system - phone start normally no issues - when I restart to bootloader - no TWRP exists, its replaced by stock recovery
Scenario 2, I tried couple of other ways and still the same thing happens - twrp 3.0 get erased.
not sure what I am doing wrong but TWRP doesn't stick
since this is my active device - i flash system.img and boot.img to get the phone to working condition
thanks for your help
