Q: I have rooted n1. when I go to recovery to do backup, I get the triangle with the little green android guy, but phone is stuck there. I have to remove battery to reboot phone. What have I done wrong?
A: You still have the stock (shipping) recovery. If you want a different recovery (Amon RA's), download it, the from fastboot, run fastboot flash recovery downloaded_recovery.img

I'm a noob but, I had this problem too.

One of two things solved the problem.
First, I had moved ROM manager to SD from application settings, and the problem went away when I moved it back to phone.
and/or...
Second, from ROM manager there is a use alternate recovery button (Amon RA's).

After doing both of these things the triangle went away.

Clearly I'm showing my noob-ness. It turns out you can hold down volume up and the power button when you get this triangle, and eventually recovery will come up.

Helpful thread.

My nexus is build grk39f with 2.3.6. I have android ask and I was able to unlock it. I just need to know exactly what to type to flash recovery and gain root. I've tried so many things. I put my zips in my platform tools folder. My set up is good I think I'm just typing the wrong commands or have the wrong punctuation. Please help.

to flash recovery type
fastboot flash recovery recovery.img (recovery.img is the filename of ur recovery)
also to fastboot recovery it should be in image(.img) format and not zip.

One more question, can I flash recovery without it being rooted or does it have to be rooted first and what's the best-known easiest root tool for the 2.3.6 firmware? Thanks for your help.

you dont need to root once you hv unlocked bootloader...
flash recovery and then flash su.zip

PLS help when trying to flash custom kernal to my xperia rooted it shows that device must be rooted first. I have rooted it with Doomlord's method. PLs help

Ok so I am a moron, but I hope someone can help me out. I have a Pantech Element (FREAKIN SWEET) but I tried to 'unroot' it. The short of it is I did it wrong. now it will boot to the recovery mode but will not mount internal or external sd. My pc will connect and show it connected in drivers and on the pc screen where all the disks are listed. ADB and Fastboot will not see it and when I try to run a command to it all I get is :error device not connected, or 'waiting on device'

Am I screwed or is there a way to fix this? I figure if I can get into boot loader I can load cwm again and life will be good but I am not aware of a way to get into bootloader w/o going through ADB, I can get to the s/w upgrade, screen but no usb connectivity to pc. Please help, I miss my baby.

Custom partition Flashing with FastBoot

---

Hi,

I want to flash a new partition which is not list below, how to identify the list of partitions name that I flash using FastBoot?
Please help..

Regards,

Notable fastboot commands:

fastboot devices - If you don't know anything, this is the ONE thing you have to know.
fastboot devices will give you a list of devices connected to the computer. This is also a good way to make sure that your phone is actually connected to the computer.

fastboot reboot - this will reboot your phone normally
fastboot oem unlock - this will unlock your bootloader - NOTE THIS WILL VOID YOUR NEXUS ONE WARRANTY
fastboot erase XXX - Will erase the partition XXX (such as userdata, cache) - mainly used for resetting phone and clearing userdata / factory settings.
fastboot flash XXX YYY - This will flash XXX partitionn with YYY image.
e.g: fastboot flash system system_update.img will flash/update your system partition with an image called system_update

If anyone needs me to dig deep into using anything else, please PM me. I'll add it on here. Hopefully this will help all newbies about the basic commands and what they do.
