[Q] bootloader issues - myTouch 4G Q&A, Help & Troubleshooting

I am trying to get into the bootloader of my device by pushing up and power but it vibrates twice, nothing comes up and the orange led keeps blinking
I got into the stock recovery on accident, and it wiped my bootloader? I did the temp root and tried to push the engineering bootloader it still won't work.
edit: nevermind. LOL

To get to the bootloader, you hold Volume Down and Power. (The jury is still out on what Volume Up and Power does.)
The stock recovery first shows an image of a handset inside a triangle with an exclamation point, or something like that. Pressing Volume Up and Power then reveals the recovery menu. I assume you'll be replacing that with a custom recovery image soon.
If you did the command properly to flash the engineering bootloader, then your device should boot up and you'll see hboot 0.85.2007 on the second line of your bootloader. If your device doesn't boot, then I'm afraid you're screwed.

Messed something up: probably radio config I think :s

What's wrong:
I cannot go in bootloader mode with the hardware keys.
When I press vol up + trackpad + power i get 3 short vibrates and charging led flashes, screen stays off.
I can access bootloader if I use reboot bootloader from a adb shell.
This is what happened:
I have bootloader 0.84.2000 PC10110000 (eng hboot) and rage method root on desire-z with stock rom (1.34.405.5).
I also flashed godspeed OC kernel
I wanted to protect myself from losing root and s-off if I would do the ota update.
I have read that gfree would accomplish this.
So I decided to do this, but I made the mistake of doing this within recovery.
I ran gfree, but my sdcard wasn't mounted, So after a reboot I didn't find the backup of my radio partition, this way I lost my original radio config partion.
When I rebooted, I wanted to check my S-off was still persent or not. and I couldn't get into the bootloader.
I got 3 short vibrates and a flashing red/orange charging led.
I can access recovery and bootloader from adb shell with reboot recovery/bootloader.
I know what I did wrong, but don't know how to fix it.

try vol-down + power
Here's a post explaining whats going on:
Here's someone else with your same problem:

I got a question.
I did this last week, and it seemed that it was done successfuly. The problem is that I tried to boot into recovery by pressing Volume + and power and I got three vibrations and the LED light just flashed red. I had to battery pull to be able to get the phone going again.
So that means I can only access recovery through ROM Manager, which makes me uneasy because it means that if I get a boot-loop I could potentially be screwed...

steviewevie said:
That's not how you boot into recovery. The good news is that you have proved you have radio S-OFF, because unless you have that then you don't get that flashing amber light state. You put the phone into a different recovery mode where I believe a PC can talk to the OSBL, but currently we don't have any documented procedures on how to use that mode.
You can get into recovery by holding Volume *Down* and Power, then you'll get into HBOOT. Then you can choose the "Recovery" option and it will boot you into Clockwork Recovery (assuming you've got that flashed).

So actually all of us who have used gfree have this same function, wouldn't actually call it a problem, just another unexplored utility.

Hey
Thx for your response, I tried the vol down and power and it worked.
I'm glad to see my phone is still ok.

[Q] Can't get into recovery...

For some reason I can't boot into recovery mode. Yesterday I tried to flash the PAC ROM but got stuck in the "PAC is loading" screen. I had to turn off and flash back to stock with RSD light. Now, I can't get into my recovery (TWRP 2.5.0.0). When I use adb to get to recovery I get a screen with a fallen over android with its hood open and a a red triangle with a exclamation mark in the middle. I've tried to re-flash TWRP but that doesn't change anything. I'm assuming this is some kind of error, anybody know what to do? I've also tried to use cwm but I can't get into that either.
Also, how do I not get stuck in that "PAC is loading" screen when flashing?

The easiest way to get into recovery is to power down, hold all three buttons and select recovery. Try wiping data after flashing PAC. Make sure your boot loader is unlocked.

Yup, did all of this, same result. My bootloader is unlocked.

couple of things:
1.) battery could be low, and thus unable to boot up. I would suggest plugging it in (outlet, not PC). let it sit for 15 minutes. you should see the battery charging screen. after waiting 15 minutes, try to get into recovery via power+volume up+ volume down, then select recovery
2.) doing the RSD could wipe the recovery - are you able to boot up normally into the ROM? if not, make sure you have all of the drivers installed on your PC, and re-read the installation instructions (I'm sure you already have, but sometimes going over them again might open your eyes up to something you forgot)
I'm not sure where it is, but see if you can boot into safemode (google search for it).
my only similar experience is when I tried to install a custom kernel on PAC, and nothing would display on my screen (despite me hearing notifications). I tried several times to get back into TWRP, but finally got it after pressing the three buttons, waiting about 10 seconds, pressing volume down one time, then volume up once (the pattern to get into recovery)
hope this helps.
RSD flashes your stock recovery again.
Hold volume up + down + power, wait for 5 seconds for the phone to power off.
Then hold the same, volume up + down + power to get into your menu screen, select adb fast boot and flash your recovery. (fastboot flash recovery YOUR_RECOVERY_FILE.img)
Power + Volume Down (-) = Reboot
During reboot:
Press and hold Volume Up (+) = Recovery
Press and hold Volume Down (-) = Fast Boot
Press and hold Volume Up (+) and Volume Down (-) = Boot Menu

Can't boot to bootloader

I recently got the update for 4.4 notification, clicked it but then the installation froze on a picture of android with an exclamation in his belly.
After that I could no longer boot to bootloader or recovery.
I tried fastboot but I cant not install the drivers as I cant boot to bootloader.
So I tried NRT and managed to get my recovery back (TWRP), but still no bootloader.
I have the option to return to stock on NRT but I am afraid it will fail and brick my N7.
I have SuperSU, flashify and TWRP apps running now with TWRP recovery also bootable.
How can I get my bootloader back?

Hi, Siddy1200...
If you had no bootloader... nothing would work... at all.
The bootloader underpins everything you do with your Nexus 7. Nothing happens without one... in which case , you'd be effectively HARDBRICKED.
The fact that stuff is working indicates that your bootloader is fine.
To access the bootloader manually... shut down the Nexus 7 completely.
Press and hold the VOL DOWN button...
Whilst holding, press the POWER ON button, for around 5-10 seconds...
You should now boot into the bootloader.
This key press sequence should also work if you CAN'T shut down the Nexus 7 normally... for example, if you're bootlooping. I've had a few scary moments myself in the past, and the VOL DOWN+hold, POWER ON sequence has always thrown me back into the bootloader...
Rgrds,
Ged.

Thanks for the reply Greg.
I can't boot to boot loader, that means when I power on with vol- pressed, then select boot loader and press power , it doesn't work. The screen flashes for a second and it is back to the previous screen to where I can choose restart, recovery, boot loader,etc.
This also happened with recovery but I fixed it, now I'm trying to fix the bootloader

Apologies, Siddy1200... but I'm a little confused... based upon my reading of your post... I think you're already in the bootloader!!.
"...it is back to the previous screen to where I can choose restart, recovery, boot loader,etc..."
The bootloader features a green android, lying on its back, with it's belly open - some really tiny text at the lower left hand side of the screen giving details about the current bootloader version and it's lock state. At the upper right hand side of the screen, adjacent to the power button, are selectable options via the POWER BUTTON, which can be cycled through with the VOL BUTTONS... and these options are START, RESTART BOOTLOADER, RECOVERY MODE, POWER OFF... and then START again.
Somewhat similar to your above quoted description.
Selecting RESTART BOOTLOADER will just bring you back to where you already are... ie., the BOOTLOADER.
Also, if you can't access the bootloader, how are you managing to boot into TWRP?... as this is normally done via the bootloader... ie, by selecting the RECOVERY MODE option.
Rgrds,
Ged.

Thanks for your persistence Greg, I think I was confused as what the bootloader actually is, now I can see I am already in bootloader :silly:
I will return to stock with NRT and try the 4.4 update now.

Volume Down jammed - can't boot past the bootloader

Hi
The Volume Down button is jammed (the phone fell and landed on its edge slightly crushing the frame where the volume down is). Curiously the Volume Up button still increased the volume.
After turning the phone off the problem came when turning on the phone as it now only boots into the bootloader as a result of the jammed Volume Down button.
Once in bootloader mode, the volume up/down buttons do not change the reboot options - it appears the stuck Volume Down button is causing this.
The way to fix this is to take the phone apart (as per the Youtube clips) and physically straighten the frame.
This is no easy task, so the question: is there a way around this so that the phone can boot?
It's rooted and fastboot commands work. (I installed TWRP but can only boot to recovery with adb).
Any help will be appreciated. Thank you.
fastboot reboot system?

No, the device is reading the hardware correctly and booting to bootloader. The only way to fix this is to fix your device.

He said he could still issue fastboot commands. If the device is OFF and he has to press the POWER button to turn it on, it is reading the VOL DOWN as being pressed as well. If he issues the reboot command in Fastboot, it should boot into system because he won't need to press the POWER button and VOL DOWN (being pressed by the bent frame) at the same time, right?
OP also said he could get to recovery from ADB, but I think he meant Fastboot because ADB is only available when you are booted to Android.
Clarification
"I installed TWRP but can only boot to recovery with adb" is unclear.
I was meaning that one can only boot directly to recovery using adb. In fastboot, one can't get to recovery.
At the moment adb can't be used - only fastboot.
When I issue the fastboot reboot command, it just returns to the bootloader. I was hoping it would bypass the Volume Down state, but sadly no.
Thanks for your input though - I knew it was a longshot.
By the way, the phone wasn't dropped, but came out of my pocket going up some stairs - the bigger size makes it not as stable!
A bit late to reply, but for the sake of the next guy that comes looking, the command you were looking for is:
Code:
fastboot continue
This should tell the bootloader to boot into system.
You are still right about not being able to boot into recovery from bootloader (that's the headache I am currently having)
Any way of disabling the volume key altogether without doing anything physical to the phone?
I tried editing Generic.kl from /system/usr/keylayout/, but that only makes a difference when the phone is booted, not before that. Any way to disable the key before the phone has booted?
Cuz this is my mum's phone and she will have no idea what "fastboot" is

Update to marshmallow failed

I'm stock 5.1.1, unrooted but bootloader unlocked. Tried updating with ota but ran through the stock recovery Android booted and it said update failed. Do i have to relock the bootloader? Again, im NOT rooted.

Also, when I tried booting into recovery manually, after the bootloader unlocked warning screen came up, it went to what was supposed to be there stck recovery but instead was the dead (lying down) Android with this words "No Command" over him. That's all, no other anything. I Powered off and booted back into Android.
BTW, got the phone second hand....
Download 6.0 and flash in fastboot.
You can also use my thread, but remember, there provided files are for EU version of Moto X Style. If you are using another device, steps will remain the same, but you will need files for your device!

The dead Android is stock recovery. Hold the power button then tap the vol + button. That will take you into the recovery menu.
From LenoMoto:
Code:
With the phone powered off, press and hold the Volume Down button and the Power button at the same time until the device turns on.
Press the Volume Down button to highlight "Recovery mode"
Press the Power button to restart into Recovery mode.
You'll see an image of an Android robot with a red exclamation mark.
While holding down the Power button, press the Volume Up button.
