Can't boot into recovery!

I just rooted my Nexus 1 Froyo per instructions on theUnlockr.com. I installed ADB first, Then proceded to root. I then flashed a recovery rom: recovery-RA-nexus-v1.7.0.1-cyan.img. This was successful. I then booted phone into recovery mode. Selected recovery and the first couple times I received a black screen with an exclamation point in the middle of a triangle next to green android. I flashed recovery rom once again and this time it allowed me to enter. I made my backup image and even booted into recovery mode again�wiped phone clean and restored image. I thought I was golden! Later I tried to boot into recovery mode again and I received same problem as mentioned above. I tried again no luck. I even flashed recovery rom again and It still dose not work. Why could this be happening? I even went through the steps to root phone again (that went well). But still no recovery mode. I even tried another recovery rom: recovery-RA-nexus-v1.7.0.1.img. It did the same thing. Worked one time and then nothing! I need to fix this before I load custom Roms.

I was able to flash recovery via your instructions but phone STILL will not boot into recovery mode. I hold down the volume key and power.....all I get is triangle with droid net to it. Im going to try and Un-root my phone and start from scratch! Thanks for the help!

you are getting the triangle with the droid because the recovery did not flash correctly, try usung rom manager if for nothing else, just to install Amon/clockwork

Did you remove the two scripts like you were told? /system/etc/install-recovery.sh and /system/recovery-from-boot.p

Cool thanks for the advice! I did try Rom Manager and used Amon/Clockwork recovery. After flashing the Recovery Image I booted into recovery from Rom Manger. No problem! BUT.....when I rebooted phone from recovery menu I again went in to Rom Manager and tried to Boot back in to recovery and I got the triangle with the Droid next to it. I pulled battery and started phone again. I flashed Amon/Clockwork recovery again from Rom Mang. and again I was able to successfully boot in to recovery. This pattern goes on and on. It seams that every-time I want to boot into recovery I need to flash Amon/clockwork image. Somewhere phone is not retaining the information. Everything looks to work just fine as long as I Flash before I go into recovery. I'm sure this is not the way it should work. Any ideas?

Khaytsus,
When was I told to remove the two scripts? Where did this come from? Please let me know what they are for and why removing them would help? Also, if I do need to remove these would it be done by using Root File Manager, finding file and selecting delete? Sorry if I sound new to this.....it's because I am! LOL. Thanks for any help you can provide!

Try this.

It's documented in random places, of course the post below also has the same info. I don't know precisely what the two files do, but they apparently try to restore the recovery.
Trust me, it will fix the problem. Remove them, re-flash recovery.

You saved my Droid! You were right! deleting those 2 files worked. I'm well into flashing Custom ROMs. Your the only one who got it right! Good job! Thanks Again!

So, I'm not the OP, but I am having trouble deleting the files despite the fact that they are both say "YES" in read and write in properties. I tried to reflash from ROM Manager and I keep getting an error there. Not sure what to do.
BTW, I'm using a Galaxy Nexus. Would love some help as this is all uncharted terrain for me.

If I understand, your problem is that you can't actually flash a custom recovery from ROM Manager ?
Which do you use ?
Are you trying to flash a recovery in recovery mode ?
Please link here files you tried to flash.

I can't flash from ROM Manager. Initially, I didn't want to purchase the download capability. So, first, I used the program tools and flashed from there. I got Clockwork Mod to work, but then when I restarted it and went into "recovery," I got nothing.
Now, I can't flash at all.

The galaxy nexus should have fastboot capabilities, this is the best and safest way to flash your recovery partition
Be sure to use the proper recovery image for your device
If you need help finding it or setting up fastboot let me know

I have only ever found a guide for a temporary flash. I would follow the instructions and then CWM wouldn't stick. =\

So here is the typical steps to follow
fastboot oem unlock
fastboot flash recovery nameofrecovery.img
And that's it, were you using fastboot to just boot it? Were you doing another method? The more details you give the faster and more accurate your help will be

I used instructions from http://androidforums.com/internatio...root-samsung-galaxy-nexus.html#enter-recovery.
The ROM wouldn't "stick" and then the USB wasn't even recognized by the end of everything.

Start by booting into your bootloader and writing down everything word for word on that screen here. Next boot to recovery and write down what you see there. Even better upload pics of each. Again the more detailed you can be the more help you can get

Help!! can't boot phone

Hello,
I just got my One today, and I've been trying to root it and stuff. I unlocked the bootloader successfully, then tried flashing the custom recoveries. For some reason only cwm (regular) worked; the other ones (cwm touch and TWRP) flashed successfully, but when I tried going into recovery, the phone would be on the "booting into recovery screen", then just turn off.
Anyways, I just continued with cwm regular, but it kept saying "can't mount /cache/recovery/command, log, last_log,..." basically lots of that stuff on the bottom. I ignored that. Then, I put superuser.zip into the SD card, but clockworkmod could not find the sd card stuff.
Finally, in CWM, I formattted /system, /sdcard, /external_sd, /data and /data/media. Then the phone would ONLY boot straight into the bootloader (even if I did NOT hold down), could not even open recovery. So I flashed the same cwm recovery again.
Now I can only go into bootloader and recovery. Sorry for the long post, and thanks for any help in advance.

I'm just guessing but I think it's because you formatted everything and never flashed a rom. So there's just nothing on your phone, it can only boot into the bootloader because everything else was formatted.

That sounds reasonable. Does anyone know how to "put" something on the phone? even just stock stuff, so I can boot?

Relock your bootloader then use an RUU. Then unlock and try again.

The thread will eventually drift away. Next time, post in the Q&A forum. More importantly, don't rely on a toolkit to save you. Sometimes, they don't work. The actual fix to this problem is fairly trivial (and to poster above, doesn't necessarily involve ADB either). If were trying to simply push stock software back on, it's three (well, in your case two) fastboot commands:
fastboot flash boot <path-to-boot.img>
flash system <path-to-system.img>
After unzipping a factory .tar. It's worth learning how to do in case this happens again.

Back to 4.1.2 official from 4.4.2 custom easy way !!!

Hello , i'm from Romania and i find a easy way to go back to 4.1.2 official from a custom 4.4.2 rom.
I search on internet but i did not find some easy way to install official firmware.
I'm sorry for my english but i hope you will find this thread very usefull.
Ok let's begin:
1. Charge the phone.
2. Open LG mobile support tool official.
3. Turn OFF the phone.
4. Press VOL- and plug the USB cable until you see S/W Upgrade.
5. LG tool will find your phone on 4.1.2. It OK.
6. Go to Options - Country and language and select your country and language.
7. Go to Option - Upgrade recovery.
8. Then the LG tool will search your phone firmware and will automaticaly download latest firmware and install .
9. The phone will reboot, and the logo LG will remain on screen, in my case. Do not panic. Unplug the usb cable and press power button to close the phone.Keep pressing untill is off.
10. Press VOL- and Power to enter recovery mod, do a factory reset, wait for the green robot to finish, restart and then the phone will boot official 4.1.2.
Now you have official 4.1.2 fast and easy.
Good luck !

Thanks for share .I think restore Nandroid backup is easier . With your method you have to reunlook bootloader and to root your phone after downgraded to stock firmware.

Thing is, people often neglect to make a backup before changing ROMs. And don't worry about the bootloader, that one stays unlocked. Root access will be gone though, but that can be a good thing. This is a good method, also very useful for reviving bricked devices quickly and with ease (in which case you have to choose the option 'force update').

With my method the bootloader remain unlock.

Even nandroid backups are useless at times.For example when your internal storage gets corrupted really bad even formatting wouldn't fix it.In this case I've just bricked my phone by corrupting the internal storage for the 3rd time just this week and only LGMsupport can fix it. (even tried makeext4fs command, nothing helps.)
Also you only need to flash a custom recovery, no need to root or unlock the bootloader.

Hello,
Can U please confirm that ?
i've always been thinking that using any LG tool to "restore" stock rom automatically remove the root.
BTW thanks for this tuto that should be useful in case of emergency

I meant you don't need to reunlock your bootloader or root again in order to flash a custom ROM after restoring your phone's firmware using LG mobile support tool.
Using some adb command you can flash recovery from your computer without needing root.

Sorry guys. I'm a bit confused here... Does that method relock your bootloader or not? If it does, I know that there is a limited number of times you can lock/unlock your bootloader. Can someone explain a little more about that? :silly:

reflashing a kdz doesn't relock the bootloader. (which is what this method does)
however, note that this method, as written here will fully wipe your internal sd card. to avoid that, before doing any of this, boot to custom recovery and format system, data, cache & dalvik cache partitions. then proceed as planned, but on step 9, your phone should not be stuck on boot logo, but it should boot into first login screen

Bootloop after backup

Could use some advice here guys. I'm stuck in bootloop from simply backing up my system. It seems anything I do in twrp other than doing a reflash of the Rom and gapps is bootlooping me. Again I can flash fresh and start over but I can't do anything else in twrp without a loop. I even tried restoring the phone to the backup that I made just before the loop

From bootloader, enter the following fastboot command:

See if that helps.

Nexus 6 5.1.1: Stuck In Boot Animation After Rooting

Nexus 6 stuck in boot animation
I've searched but was unable to find anything to help. I am a noob to rooting. The other day I rooted my Nexus 6 using chainfire. After I installed an app I wanted. In order for the app to work I had to reboot. I rebooted and now the phone will not fully reboot. It gets stuck in the floating dots. Anyway to fix this? I'm on Lollipop 5.1.1 T-Mobile. Thank you.

what app did you install? thats a very important question..
you can always go into your recovery and wipe data, which will let you boot, but you would have to reset up your phone after that.

yes. in your phones main settings, backup and reset, press the factory data reset(but you cant do it because you cant boot up). you can flash twrp for a one time use only, btw. instead of flashing it permanently. use fastbboot boot recovery recoveryname.img instead of fastboot flash recovery recoveryname.img. after, it will disappear and go back to stock recovery.
