Dear all,
my N1 is now in 2.3.4.
I wanna root it without dealing with the bootloader.
I searched some related posts here and found that I've to firstly downgrade my N1 to 2.3.3 by getting into the recovery mode by pressing Vol Down + Power buttons to power on the phone (is it called "recovery mode"?)
Yet my power button has been broken.
I then tried to get into the recovery mode with ADB in my PC with the following command: "adb reboot recovery"
My N1 then started to reboot and it finally freezed at a screen with an android robot with a caution sign nearby.
Q1)
So have I done anything wrong to get into the mode which is supposed to be gotten into by pressing Vol Down + Power buttons?
Q2)
What should I do to downgrade my N1 and finally root it?
Thanks a lot!!
You should read the Wiki and follow Unroot/Restore guide, PASSIMG method.
But without a functional power button, you can't do it.
Moreover, without a functional power button you can't unlock the bootloader either.
So, actually, you can't do a thing until you fix your power button.
You can do the passimg without a working power button, because you use volume up to confirm...
Fixing the power button is smart though!

The required mode is fastboot.
"adb reboot bootloader" should take you there.

You are either doing it wrongly, or the volume-down button isn't working. It's as simple as that.
To diagnose, make absolutely sure that CWM is properly installed by following steps 1-3 in this guide.
EDIT: Actually, if volume-down isn't working, you won't be able to start the phone in NVFlash-mode either.
Then try to start recovery again (also by doing it exactly like the guide says.) If you still can't access CWM, then you know for certain your volume-down key is broken and you need to get the phone repaired.
Maybe a "quick shot" but why not to ask: do you keep power and vol down keys long enough? You have to keep them pressed both for quite a few seconds before CWM mode is activated and CWM menu appears. So, just power off your phone, then keep power and "vol -" buttons pressed until the LG logo changes a bit or the CWM menu appears. On my phone it takes about 15 seconds, so no hurry
So I installed a TWRP RECOVERY a Motorola RAZR i, using the Flash Tool.
It installed but I could never access it from the POWER VOLUME UP & DOWN method.
So I had to turn the phone on and enable USB Debugging then use ADB to reboot into recovery via the Flash Tool.
Then I was working on a PORT when I flashed a ROM, it went into bootflop, now I cannot get into the BOOTLOADER at all.
It never works, it will show the normal warning sign and then just go straight to the ROM.
I tried using RSD with an SBF File but it did not work, as I have to be in fastboot and I cannot be in without going into the bootloader.
Is there no hope for this device...
I have the feeling that twrp isn't flashed right. U did use fastboot?
For the bootloop. Hold volume down the whole time when it boots/bootloops, it will boot in ap flashmode (fastboot). Maybe u need to stop pressing the button after the first restart(when holding the volume down button) at the moment u get the warning.
Easily recoverable, just need some trying with the above way.
Sent from my XT890 using xda app-developers app
My method to come into fastboot-mode while having a bootloop:
1. when in bootloop press all buttons (power, VolUp, VolDown) and keep pressed
2. when screen goes off, leave the VolUp button alone, keep VolDown and Power pressed.
3. when phone vibrates, leave power alone and keep VolDown pressed
4. the bl-unlock-warning shows up and after a few seconds you should be in fastboot-mode
5. now you can leave VolDown alone
Maybe you need some tries, cause its a question of timing, but for me it works.
Thanks...
@icual
I am very grateful for your help. Thank You ever so much. The solution worked perfectly. You saved my phone
Hello. I have a razr I and decided to unlock the bootloader. I tried the button combination power + volume down several times, but the phone just powers up normally (actually rhe screen flashes for a second, but doesn't go into fastboot mode. I trided using adb reboot fastboot but the device just reboots. What can I do about it?
NVM, just did it by fastboot reboot bootloader...
Ok, one more thing. It seems my device ignores the key combo, but I was still able to get into fastboot mode by using adb. However, I have tried to flash a custom recovery with no success.
I tred using the supplied installer and after rebooting I get to the open robot screen with the red exclamation mark. Then, after holding some keys (not sure if power or power + volume down I get into recovery, but it's still the stock android recovery. Then I tried flashing the recovery image from fastboot mode. It sait the recovery was flashed, but still cannot boot into recovery. What's wrong with my phone?

Just incase you need to do it in the future:
Hold volume down, then hold the power button. When it begins to vibrate release the power button and keep the volume down button pressed until you get into fastboot.

Alright. So how about the never appearing CWM recovery?
My phone was frozen when I was taking a video,
then I forced restart the phone by pressing power button until it restarted.
However, my phone stuck at the android logo for a quite long time with the screen on, so I decided to do a factory reset.
I have tried the following steps on my friend's phone as we bought exactly same phone,
and succeded at first attempt.
1, volume down + power button goes into boot options.
2, then android logo, then about 2 seconds later, dead android guy would appear.
HERE is my phone's problem:
in this step after showing android logo, my phone would vibrate once and then just gone black,just like turning off. NO DEAD ANDROID GUY showed up. Certainly would not be able to do the rest steps.
I have searched and tried so many methods that others used when they could not get into the bootloader. NONE of them succeded.
So I need help, guys.
Anyone got any ideas.
Thanks in advanced !!!
no one ?
I guess I had to bring it to the store for repairing.

1. power button + volume(down) button
then in bootloader menu:
2. volume(down) button to goto down to 'recovery'
3. volume(up) button for selecting it
Alternative I would try this:
power button + volume(down) button
then in bootloader menu stay here connect usb and use fastboot on pc.

Have a SM-T813. Attempting to use Odin to flash TWRP. All goes well be it keeps rebooting back into the normal recovery. I've tried different methods....with and without auto-reboot. I've read where some devices will replace the updated recovery if the proper key sequence is not used but I think that may be part of the issue. When done flashing I hit the power button and vol down button but instead of powering down it seems to power back up/reboot precluding me from hitting the proper key sequence to enter recovery mode. Home + Vol UP + Power.
And btw I have Allow OEM Unlocking and Allow USB debugging set.
Am I missing a procedure?

I have a 713 and the procedure is kind of funky but is the same. See lines 5-7 below. You literally need to move one finger from volume down to volume up while the fingers on power and home stay put.
https://forum.xda-developers.com/tab-s2/development/twrp-3-0-2-1-galaxy-tab-s22016-sm-t713-t3390627
Flash with ODIN 3.10.7 in the AP slot.
Put your device in DOWNLOAD mode.
Uncheck Auto reboot.
Load the respective file below into the AP slot and hit start.
After flashing and ODIN reports PASS immediately reboot to recovery by holding POWER + HOME + VOL DOWN.
As soon as the screen goes blank change to VOL UP whilst still holding POWER + HOME.
You should now see TWRP recovery.
Yep finally figured out the one finger deal from vol down to vol up. Installed and working fine now.
