[Q] how to enter stock recovery in JB

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.

Hmm I have not gotten into recovery on JB even once...can't get in.

help please!!
i have de same problem
when i push power button, the green led turns on for a few seconds and then the phone get off... i can not enter into recovery mode either
anyone know how to fix it or fix it already
thanks!! :crying:

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?

[Q] Black screen after reboot

I have tried to boot into bootloader couple times before on stock settings, with nothing flash or modified.
Whenever I tried to restart, it stuck on the black screen with no LED when plugged in, and it won't turn on or boot for about 10-15 min.
I was trying to solve this issue by wiping the entire phone but still happening. Now that I have tried TWRP with ARHD 12.1, the problem still there.
I have also tried fastboot erase cache, doesn't fix this issue either.
Tried to hold Volumn down / Power button for a long time, it still doesn't do anything until 10-15 mins after.
I assume that the device is still in process and somehow is getting stuck somewhere that it doesn't listen to the input anymore until there is signal shutting the whole thing down.
Since I couldn't pull out battery on HTC One, there is no way I can verified if that is the case.
Anyone else facing the same issue?
I am kind of sick and tired of sending back and forth for RMA, which I already did for dead pixels before.

Thanks for the help
I am under sunlight, thought that could have help, but it didn't....
I guess I will try flashlight next time..
but the problem still not solved, I do not want to get under the light every time when I am trying to make a restart on HTC One..

I found a pattern of this issue, it's seems to related to the USB connecting to a computer.
Somehow it won't let my phone shutdown properly and stuck with no screen showing.
Power button + volume won't work for about 10-15 min.
But it can boot back up after that 10-15 min normally. This is a strange issue.
It happened ever since I tried to access bootloader, but I have not change anything.

Mi 9 infinite loop on the boot screen

Hi- So I was using chrome on my Mi 9 and when the screen locked the actually went off. Now it doesn't turn on. If I press the on button then all it does is show me the Mi logo and then it goes to black and then the logo again, sometimes the logo turns orange but either way it doesn't turn on.
I don't know anything about custom ROMs so I have my phone stuck, also use it for whatsapp, youtube and chrome, no games, no nothing.
Can someone help me fix this? I don't even know where to begin. I have the global version and upadated to MIUI 11 back in November I believe.
Oh and I just remembered my phone did this like 2 times in the past but it eventually booted fine. This time is not working.
Thanks,

Hello
I assume your bootloader is locked.
You can try to boot to recovery (Power + Vol up) dans wipe data. On the most case this could fix your problem.
BTW you'll lost all your data.

Phone stuck on boot loop and won't turn on

Phone got frozen while in Messenger, suddenly turned off and now it's stuck on boot loop. Holding volume down and power button does nothing, keeps it on boot loop. When I put it on charging, it heats up, but the charging logo does not show.
Anyone got any clue what might be the problem or how to solve it?

did you receive any pictures via messenger ? that used to be a thing that messed up phones because of one colour outside most phones RGB range.
a bootloop is a cycle, catch it at the right time and you can boot into recovery to clear cache and dalvik.
remember recovery and download mode need the cable plugged into a USB device to nowadays.
the instant the screen goes off hold volume up and power and then plug the cable into the phone (the other end already being in the PC).
if you did receive a file before your problem that'll still be there and the problem might persist. you might need to boot up into safe mode and delete something.

The phone got frozen at the main screen of Messenger, haven't received any messages or pics.
The thing I haven't mentioned but dk if it means anything, sometimes it gets to the Samsung logo, but then it goes off and turns back on.
Tried to hold volume up and power button couple of times, sometimes it would do a strong vibration and then do nothing, but I'll keep on trying.
Thanks for ur help

don't forget the USB cable, you can't manually boot recovery without it.

if you don't mind losing messages next time you could try clearing data on the messages app. you'd need to be pretty quick by the sound of it.

Pixel 4 xl bricked, doesn't boot normally

Yesterday, I am using my phone as normal on work. In couple seconds it turns off and that's all. It doesn't charge. But I can boot to logo via press power button for a long time until it powered off. If I release power button, it stops boot up. Second interesting thing, I can go same way to fastboot with same issue. I can't use button navigation in fastboot, because if I release buttons it powers off. Please help me to solve this problem. I don't know how use fastboot like this.

It might be battery issue. You can manually flash the factory image one by one. While holding the power button but it won't be easy. But it likely a hardware issue.
