battery loop problem

Hi,
I have been running cm10.1 for a while on my galaxy note. I recently upgraded to 10.2 nightlies. Yesterday I opened the stock camera app (not focal) and when i clicked on capture the phone froze. So I had to pull out the battery. After that the phone would not start. I had full charge when my phone froze. When I connect a charger I get a battery logo with a loading circle icon. However this icon keeps flashing like a loop.
I am not able to go into recovery. But I can go into download mode only when I connect a charger or to the computer. However when I press volume up to confirm download mode, it exits it and the battery loop starts again.
Could someone please help me fix the issue.
Thanks

Thanks ThaiDai. I put back my old defective original samsung battery and it booted.

I have similar issue. Flashed CM10.2 everything seemed to be working OK until I tried to go back into recovery and flash an update. Will not reboot from an attempt to go into recovery unless you plug in until you get green battery icon, then unplug and phone will boot. Once booted everything seems to work ok, you can reboot phone, download and install from play store, even reboot the phone, but any attempt to go into recovery will cause the device not to restart.
So, I can't flash anything, including a new recovery.. LOL... I'm wondering if this might be a battery issue as well, but I don't have a spare battery to try.

[Q] Bootloop, can't get phone to stay in Download mode to reflash

Hi all
I reflashed an old i9000 with CM10.1 for my wife recently, and everything seemed to be working fine. Then it started behaving a bit funny and this week it started rebooting at random. I thought "no worries, I'll just do a fresh flash with stock GB".
However, before I could even give that a go the phone started acting even weirder. As soon as I put the battery in it powers on (without me even pushing the button) but it resets every time it hits the Samsung splash screen. Earlier today I could get it to go into CWM recovery and after clearing cache I actually got it to boot up. But by the time I had downloaded the stock GB files the phone was just constantly resetting at the Samsung logo and now I can't even get it to load CWM recovery using the 3-button method.
I can get it to enter Download mode, and it shows up in Odin just fine. But within 5 seconds it resets itself again so I can't actually perform a flash.
Any suggestions? Or is the phone just plain busted?

I'm just going to answer my own question as I've solved the problem but it may benefit someone else to know how.
It got to the point where the phone wasn't even booting to the Samsung splash screen, but I could still get Download mode to show up for 5 seconds (not long enough to flash). Then in a moment of desperation I got the original Samsung microUSB cable and plugged that in, and booted into Download mode again. This time Download mode stuck! And I was able to flash a clean GB ROM which is now working fine.
So the take-out from my experience is this: sometimes you really do have to use the original Samsung USB cable.
Weird.

Thanks for reporting howto ...:good: good to know

I have a similar issue where I'm trying to flash my stock ROM on my Epic4gTouch. When it opens up the download mode error I start to flash and all seems to work before it reboots. Every 5 seconds. I tried the original cable and it did not help. Any ideas??

Phone do not boot after Oreo update

As i installed update and clicked reboot to apply it, now my system do not boot. Phone always stuck on white NOKIA logo boot screen forever. I tried few times to restart it via VOL-UP + POWER, but it always have same result - never boots. Please give me advice how to deal with it

It happened to me too, in December already. Mobile is in service now.
They flashed original fw, tested and returned it with results no fault. Right after switch on and new Oreo update it starts to freeze and produce various mistakes again, so I have returned phone to service. Will complain with seller about exchange.

That really sucks. But what do you mean by various mistakes? Like your system boots, but some functionality is not working? As i said in my case it totally cannot boot and recovery mode i can't enter factory recovery mode by VOLUME UP + POWER on start.

Ach yes, sorry. First it stucked in logo Nokia and rebooting again... VolumeUp+Power does not work normally on Nokia.
It helped procedure found here:
https://forum.xda-developers.com/showpost.php?p=74406267&postcount=34
Then I was able to make factory reset and mobile booted, but worked with various faults.

Did you unlock your bootloader , flashed TWRP and then changed the slot? Slot A to B or vice versa?
If so, then the solution is
How to solve!
I simply waited until the battery ran out
When battery was completely dead and no Nokia-logo appear any more >>
Then I charged the battery 3% juice without booting
and from there I entered recovery-mode with the help of a USB cable.
Holding the volume+ button while connecting the USB-cable
From TWRP-recovery I changed to the other inactive slot
and whooala, that's it!
Edit: I sucked the juice (mAh electric-capasity) out of the battery quicker with help of OTG-cable and an external USB-powerd fan.
Use almost any external max 5volt USB-powered devices available at home, even charging another phone unless the second phone doesn't reverse-charge, this Nokia can be used as a power-bank.

Bootloop and nonstop Restart Issue

Helllo,
My Mi A2 can't boot into the system it keeps restarting all the time. Even when I have tried go to fastboot mode, it goes it, but after several seconds it restarts, so I can'd do anything about it.
I have tried power+up, but "no command" error.
What can I do?
Is there any solution?

Open the phone with screwdriver and short the "test point" ...then when in edl flash the stock ROM ....and anyway after that ..in fastboot boot twrp and flash a zip from the global telegram group or my other posts to restore your persist
If after that your phone still fails to work it is a hardware problem causing this ....

It is a physical process not in software so just Google a video on YouTube so you can see the physical actions and copy it

Update:
I have replugged all the cables and while battery was drained I have turned it on again.
It worked!
I even make an update for android. But after some period of time, it started restarting and now I have the same loop.
I have unlocked the bootloader while it was working, but it doesn't help me right now at all.
Phone keeps restarting...
While it was working and charghing, some application was automatically opening and sensor started making some clicks.
When I had the same ecounter with other phones, it was battery fault.
What do you think guys?

I am also facing this issue. Sometime it reboots randomly but other times it works fine. Should I roll back to Android Pie?

Hi! I am facing a similar issue: Suddenly my phone shut off. When I wanted to turn it on, it would shut itself off after ~3 seconds of the boot screen. If I plug it to charge, it would start rebooting every 3 seconds.
I have left it charging for a long time, and at a certain point it stops doing this and shows that it is fully charged. I have tried to unplug it and turn it on after this, but I am getting the same result. Once again, charged it, and tried to turn it on while connected. It turned on, but once I unplugged it (before unlocking it) it froze .
Recovery mode does not work (same result), but fastboot works. Unfortunately I can't flash it as I can't risk losing all my data.
Having said this, I want to know more details about what has worked for you. Did you drain the battery and then connected it to charge?

That seems quite cheap. It's up to you, I guess.
If you want to solve it yourself, you can give it a try to flash it in EDL mode. I have tried it with no success yet.

Bootloop

I just wanna ask after the oct update i got bootloop now when i try to go to service center they told me that the problem is the motherboard. When i explain to them the reason i just update it then bootloop they always tell me the problem is motherboard. And i need to fix it and the cost is half the price of the phone. Now i need some help. When i try to turn on its stuck to androide one then off whne i try to go to fastboot its okay. When i charge it it turns on and off. I jus need some help.

is your bootloader unlocked?
If so, have you tried booting latest twrp image from fastboot?
Code:
fastboot boot twrp.img
Sounds like you may at least have to try to wipe and format your phone at the cost of all data.
But then you could use the situation to install a good custom ROM..

If you were doing a normal update, your phone should revert to the previous slot after a few attempted reboots.
Keep trying to reboot.
If nothing else works, try flashing september version from EDL (search it on the forums).
I flashed and still couldn't boot at first. I tried restarting a lot of times, until it got on the "Retry" or "Power off" option. I let the phone sit on this screen until it shut itself off. After tried booting up a few more times until it finally did.
I was not plugged in during this.
I'm not going near that october patch ever again.

Hello everyone,
I'm using mi A2 (64gb). It is rooted and was running on Resurrection Remix 8.6.2. Somedays earlier, I let my phone idle, suddenly it starts rebooting, just like bootlooping. After seeing that I booted in recovery and wiped dalvik and cache then rebooted and the phone rebooted in system successfully. But then I noticed the power menu appearing continuously on the home screen, I tried to dismiss it but it rebooted again and so on. From then, only the splash screen appeared for 8 seconds and it reboots again. I can boot into recovery or fastboot but only for 2-3 seconds then it reboots.
I've searched on the internet and was flashing firmware manually from fastboot but accidentally, I flashed an image file in a wrong location and the phone screen turned off and nothing appeared. Then I found that it had entered in EDL mode. but still it is rebooting and I can't flash firmware from mi flashing tool as fastboot wasn't working.
This is the problem of my phone. A help would be amazing! Thank you!
Ps. I'm new here and it is my first post so if anything is wrong. I beg your pardon and sorry for my bad English.

Try shorting testpoint in motherboard then enter EDL mode,
Then use mi flash tool.need to remove battery first.
How? Watch youtube, for mi6x. Mi 6x = a2, sort of.
~yes, you need to remove/open the phone.

U said rebooting even in edl, if not. Dont. Just make sure you have enough battery juice.
Use xiaomi tools. Or not, I uncompressed the file and click flash all.
