[Q] How to reboot into recovery?

I rooted my G2 about two months ago. I'm currently using MIUI, not the latest but the one before it. Somehow, my phone got turned off and when I tried to turn it back on, it was stuck in a bootloop. I have a custom recovery image so I don't know if that affects anything. I tried to reboot into recovery by pressing volume down and power, nothing happened. I then did volume up and power. It vibrated three times and the orange light started flashing. I pulled the battery and now when I try to turn it on, nothing happens. So how do I reboot into recovery and so I can restore my backup? Any help/suggestions would be greatly appreciated.

Never pull the battery during something like that. It sounds like your bricked. Someone else confirm?

I don't think it's bricked. I plugged it up and then Clockwork came up so I selected reboot now. Clockwork came up again so I tried to restore my latest backup and the screen went black. I'm going to let it charge and then give it another try.

Ok good. That's lucky because whenever you pull on a boot like that, it usually bricks. If you have the option, try to re-flash your ROM. Maybe even try stock. If you were getting a black screen, it's most likely you flashed incorrectly.

Ok, I was able to boot into recovery and now I'm restoring my backup. I don't think I had a custom recovery image with this one so hopefully I won't get stuck in a bootloop. When you say stock, do you mean before I flashed MIUI (it was the first rom I flashed)? Thank you for your suggestions and all of your help.

first install adb on you PC, it helps a lot in these kind of cases.
1. try "adb logcat", it would tell you about what's going on in your machine.
2. once you get your adb working, try "adb reboot recovery" to see if it could boot your phone in recovery.
3. if after doing everything you fail to boot either your phone or in recovery then try using PC10IMG to boot a stock rom and then re-root your phone.

I got it back working. For some reason, I'm just starting to think that it needed charging (the battery had been out for about a day or two). I do have adb installed and configured on my computer since I needed it to root. Thank you for your suggestions, I will definitely rember them if this happens again.

lol of course when you get black screen and led blnking means your battery begging for juice, you're lucky that when the phone booted back in recovery and you tried to restore a backup the phone went off before actually starting to restore, that would've bricked your phone
DO NOT FLASH ANYTHING WITHOUT AT LEAST 40% OF JUICE LEFT

[Q] First boot loop, now wont turn on, 7 vibrations?? HELP!!

Hello, I have the HTC tmobile mytouch 4g and it is acting up. Stock phone, no roms or rooted.
Three days ago, at night, doing some browsing and then everything froze, would not respond. I removed battery, and then it did a boot loop so i kept trying for a while, taking out battery, and turning on but still boot loop, so then left it alone.
The next morning i held the power and home button and it turned on and it worked normally for the whole day! until about the same time two days ago. Doing a little reading and browsing before bed (same website too, but i didn't download anything and the site works fine on a computer) and it froze. Did the same routine except it didnt work in the morning again. I removed sd and sim card too, left everything out for a long time, but whatever i tried it wouldn't work.
Yesterday i tried all day and then I read online I should do a wipe cache partition from the recovery menu. So i did that, but it was still a boot loop. After a few tries, it stopped turning on. Now the screen doesn't even turn on, but the phone vibrates 7 times when power is pressed, then will not respond at all unless i take battery out, then it will do the 7 vibrations and etc.
All htc said is to try a factory reset, but it wont even go to that menu. I can send it to them, but will probably lose everything on my phone ( like messages, contacts, and app data?) BUT I'm convinced there is another way, since it fixed itself the first time.
Just recently, now it has started blinking the charging light when charging (i charged it about 10 hours ago and it didn't blink)
I don't really know much about how these things work, but I have been reading some stuff about pd15??.jzip and putting it on the sd card (i have access to a micro sdcard reader) Also about a stock image or something. I don't know much so please give a simple-ish answer.
IF THE SOLUTION YOU WILL PROPOSE HAS A LOW SUCCESS RATE OR HAS A POSSIBILITY OF FURTHER DAMAGING THE PHONE, PLEASE LET ME KNOW... If it is too difficult/ too much work/ or dangerous, then I don't mind losing whatever i have on the phone

The PD15IMG.zip is the "stock image." It has to be installed in the bootloader, and you WILL lose all of your data. Usually you can get to the bootloader by holding volume down while booting. It will scan for the file there. Can you get into your bootloader?

sigh
cannot turn on no matter what i hold.
I think the blinking last night meant that it isn't charging the battery anymore. wont even vibrate now unless it is plugged in. its not an issue with the battery is it??
if this stock image is going to delete everything anyway, i might as well send it to htc. i just hoped i might be able to save my messages because i have some really hilarious ones, but oh well.
Can you please tell me exactly what ill lose? so,
bookmarks on the browsers
contacts and messages
all apps (they're on my phone) and app data? (like will i lose my progress in temple run 2, lol)

I don't have this phone with me ATM.but I seem to remember when you press volume UP: and POWER it if i remember correctly would do the blinking light and vibrating a few times .Anyways to get in recovery You Press Volume DOWN and press POWER at same time should bring you to recovery and if running a custom recovery such as CWM or 4EXT you can try the wipe cache and wipe dalvik cache to see if fix issue or try if using a custom ROM you can try installing the ROM again without wiping data and system first.I Read your post and the replies and correct me if I am wrong it sounds like this might work and sounds like you are able to get to recovery from reading your post I think.I would try and confirm that you are or are not able to try these suggestions before you try the boot-loader suggestion with the PD15IMG.zip or whatever it is called ,these are assuming your rooted with a custom recovery such 4EXT if not and I read wrong again I apologize. Good Luck!

alternatively you could use adb if u installed it
1. connect ur phone via usb cable.
2. run cmd from ur android-sdk folder (or whatever you named it). by running in folder I mean, ur path in cmd should be C:/whatever-is-your-sdk-folder path
3. type this in cmd window "adb reboot bootloader" (without ")
it should load your phone in bootloader from where u can get more options like factory reset or install new rom (u can mount ur sd card in recovery & put new rom to flash on sd card)

I9505 bootlooping & not booting

Galaxy S4 I9505
Phone was second hand to me at the start of this year, though had been well looked after, always in a case etc
I flashed it with the newest stock ROM in January this year
I9505XXUHOJ2_I9505BTUHOJ1_I9505XXUHOJ2
& rooted with CF AutoRoot
It has worked fine until about 2 weeks ago, when it randomly shut down. After restarting, it kept bootlooping.
Left it off & charging overnight, & the next morning it booted ok. Managed to use spotify for a few hours.
Then it started bootlooping again, sometimes getting all the way but then crashing after a few minutes.
Managed to boot into recovery & do a 'wipe cache', that didnt fix it.
'Wipe data' didnt fix it
Have flashed the PIT file & ROM (via odin), no errors in odin, done it twice now
wiped cache & data
still wont boot past the white splash screen, only sometimes boots into recovery
(also, only the menu button lights up, not the back button.)
I've checked the power button (clicks & dosnt stick)
Dont think the batteries the issue (charges fine, dosnt get warm, isnt bulging)
What else could stop it booting?

Have you tried booting into safe mode?
Safe mode, from what I read, can be accessed by holding the menu button while the phone boots.
But you should also do some reading about it, in case I'm wrong.
The other idea would be to try a custom ROM.

Can't boot into safe mode
(& having read up on it, it would only not run apps that arn't already in the ROM)
Any suggestions for a custom ROM
& why would it work when the original official one won't?

Well, it's booted far enough to get into android & add a google account, then it bootloops again.
Then after leaving it off for a while, it will boot & let me look at settings etc, then bootloop
however
the menu soft key stays lit all the time after a boot
the top half of the phone, around the camera, gets very warm
Does that indicate it's a hardware issue?
Could it be the battery?

If it's the top half warming up without you doing anything, it's the motherboard.
Boot into recovery and and let it stand by, see if it reboots.

The battery can't prevent the ROM from booting. It would have to turn off during the boot, which it doesn't. So, by my logic, it isn't the battery.
Try official CM.

I am not able to go into recovery after firmware flash. The recovery bot appears and when the blue loading bar goes to half, the phone reboots and then again boot loop. I just noticed this always happened when i flashed a rom. I was never able to enter recovery on first boot.

Why do you want to do factory wipe after one boot?

Its the only thing i didn't tried till now, my phone crashes and reboots everytime during boot.

I was in a similar position to where it would just always boot into recovery forever. I tried doing several restores from stock and other backups. Different ROMs and even went through dirtysanta again. Nothing worked.
What wound up working was me getting into the device's factory restore screen (not TWRP's). I believe you get there by turning on the device while holding the Vol down + power button, when the LG screen comes up - let go of the power button for like 1-2 seconds and then press/hold it again. It should be a white screen that's asking if you want to do the factory screen or not. Just do that. It did its thing - then went to the LG screen again. I was a bit impatient and only waited like 2 mins. It didn't go anywhere (you could probably wait longer or so) but I just simply took out the battery and then put it back in.
It did wind up booting to the system again after awhile.
Just letting you know what I did after I messed up with a certain thing in a hidden menu.

I tried flash system.img and boot.img use fastboot flash command.
and re-flash de-odex system use TWRP again, wipe data and cache.

Thanks.

Nexus 5x will only work while plugged in...

All,
I have had my Nexus bootloader unlocked and even rooted it before.
However, I friend needed a phone so I let her use my phone...about a month later she said the battery was bad because the phone keeps cutting off.
Long story short I got the phone back and I think she picked up some type of virus or something got corrupted because I forgot to lock the bootloader when I gave her the phone.
Here's what I have found and done:
Found out:
1. The phone will turn on while plugged in after a couple of tries.
2.If the phone is not plugged in, it gets to the 4 dots and either re-boots or shuts off
3.If I turn it on while plugged in and then unplug it and set the display to turn off after 30 minutes...the phone will stay on, until the display shuts off then the phone shuts off.
Here's what I tried:
1. sideloaded Android 8.1 using TWRP (about 5 times)
2. Wipe cache and the other cached (several times)
3. Tried rooted it again...using SuperSu BUT during the re-boot it will stay on the "Google" screen for 30 minutes and not do anything...will not re-boot or nothing...phone get's really hot. (tried this several times)
4. Using TWRP recovery and if I leave the phone unplugged (while in recovery mode) the phone never cuts off.
So I am thinking one of these partitions is bad, corrupted or missing which is causing the phone to think the battery is low and cuts the phone off. Just guessing here. Maybe some malware is installed on a partitions and flashing is not during the trick.
Any suggestions???
I really wanted to keep this phone as a rooted phone I can play with and try different things.
Thanks,
Real

Not an expert but i suggest you do the following:
Backup the boot image, download the modified boot image for 4 cores. Try to boot, if it boots normally, your problem is BLOD and it will be solved. If that is not the case, use the 1 click flash bat from the modified fastboot folder that you can find doing some search, that bat will recreate partitions and reflash everything and also flash the rom you provide it then try to boot again. Shutdown the phone, give a charge until 90ish, let it cool and then boot it up.

Thank you for taking the time to reply...and thanks for your suggestions. I tried both and was very hopefuly...but did not work. The phone still will not boot unless the usb is connected and powered. However, not sure if I did the 4core correctly because I could not tell if it worked or not. I found a twrp 4core for bullhead and that is what I used. However, when you first flash it and it does an auto reboot it boots into TWRP not Android. So within TWRP I just click on reboot system...but same outcome.
I think maybe this phone's hardware is dead or something got burned out...but it is not the battery.
Thanks,

You did it wrong. You have to flash the boot.img that disables 2 of your cores. Search it here on the forum you'll find it
