[Q] how to enter stock recovery in JB

[rasaf]

Hi all,

My phone is EU retail, locked, unrooted. I updated from ICS to JB via manual download of the update and installation via SD card as explained in one of the more popular threads here. Now after the JB update, I want to enter recovery in order to clear the cache.

With ICS, I was perfectly capable to enter the stock recovery. Press power + vol. down for a few seconds, and the (fastboot?) menu appreaed where I could select recovery. Then the dead robot shows up, I pressu vol. up + vol. down and I had the expected options. Now on JB however, this does not work. It does not matter how long i hold power + vol.down, it always boots the system. When I press power + vol. down and keep holding the two buttons, the green LED goes on and off, then the phone vibrates, showes the red M and seemingly starts to boot. Then the screen goes off and it repeats the 3 steps (LED, vibrate, red M) but then goes on to boot up the system...

Is this supposed to happen?

Same here. It looks like there is no Recovery installed at all, so will try to flash one tonight.

I'm new to Motorola so need to ask...what is this stock recovery for? Is it the same as a typical 'custom recovery'? I've never heard of a manufacturer putting on in their ROM...so can I do a normal backup of a ROM or no? Thanks

Thanks, this releasing of the power button while still holding vol. down works reliable to get into fastboot. However, when I select recovery, the screen goes black? Something is not quite right with my phone...

Edit: I seem to get the hang of it. Now I finally get into recovery. When I select it from the fastboot menu, the screen gets black for a couple of seconds and then the dead robot appears. To get the options in recovery, I press both vol up + down at the same time twice. Initially, the layout in recovery is broken up. Just two blue lines at the top and a few characters in green at the left border. Once I press any of the volume buttons, the options finally appear.

The above tip doesn't work for me - either my timing is wrong or I don't understand the instuctions.

Someone else kindly explained it differently and eventually I got it working. That was posted in some other thread and I don't think it was directly related to recovery - I can't even find that post now!

I have found people saying they've got root on the RAZR M on locked bootloader Jelly Bean...but you need to access stock recovery which I can't do now.

That's the original post...I don't fully understand it.

I am grateful to that poster for trying help people - so I don't want to be misunderstood! :good:

If I were to describe the boot process to someone, nothing 'vibrates' - so I don't understand that. My phone doesn't vibrate when boot begins, and no 'i' vibrates either. Also, there are two 'i's. There is the i in Intel and in Inside. I'm guessing it's the first i. Believe me, I have tried 10 combinations like 50 times. I know it can be done, but can't do it using that post.

Nope, someone else explained it differently and I got it the first time. It wasn't a recovery thread so it's hard to find now.

Your Razr does not vibrate after boot? This is strange. Ok, let me try to describe the process based on my Razr i. (As simple as possible)

1. The mobile is turned off
2. Press and hold the Vol- button
3. Now press and hold the Power button and observe the green light. It turns on at the same time I press the Power button. The green light is on for approx. 2 seconds than it turns off.
4. Just at the moment when the green light turns off my Razr vibrates twice within 1 second.
5. I need to release the Power button before the 2. vibration and at least 0,5 seconds later the Vol- button. This is the point to get in the fast boot menu.
Without any vibration you should try to release the Power button just at the moment when the green light turns off - followed by releasing the Vol- button 0,5 seconds later.

Why did you post in Razr i forum? Wouldn'd it be more effective to post in Galaxy S3 mini forum?
