(CyanogenMod 13.0) Bootloop on MI logo, only able to access fastboot. - Mi 3 Q&A, Help & Troubleshooting

Help!
Earlier today, i tried to run geekbench 3.0 and seeing that the test will took some time, i left my MI3 and let it run.
Fast forward few minutes later, i found the device bootlooping on the MI logo... restarting and keep crashing continuously.
I'm not able to access the recovery (volume up+power button) and only able to access fastboot. I've tried flashing twrp recovery over and over again through fastboot, but no luck.
Any help will be greatly appreciated!

You should probably change your battery for a new one
This has happened to me as well, but I replaced my battery and now everything is ok.

flash stock firmware... follow this if you are not sure how to..

I just had the same like Anemiq. I was stuck in a bootloop recharging wasn't working as well. A new battery solved the problem.

[Q] Phone not booting

Hi all,
I use CM12 from MacLaw in combination with TWRP 2.8.1.0 recovery for about 3 weeks now.
Yesterday the phone didn't respond properly, was very very slow and I basically couldn't use the phone. It felt like the CPU was at 100% all the time, so unlocking the phone, calling and so was nearly impossible. A reboot (battery removal) didn't solve it, also the pin code for the sim card came after a few minutes while usually this will come right after starting.
So eventually I did a factory reset from the menu as I did on other occasions just to get rid of this kind of problems.
Well, right after the Samsung s3 mini logo I get the TWRP logo and it will be stuck in there, I see it blinking every few seconds and that's it. When I connect the phone to USB I hear it connecting-disconnecting every few seconds (bing-bong, bong-bing sound).
After a while I flashed TWRP using Odin again, this didn't give any problem but it will still hang in this TWRP loop.
I found some references to this problem but no real solutions. Someone suggested to use ADB but I don't know how to do that, nor could I find a suitable guide on this.
Can anyone help me? Or is it bricked somehow?? I suspect not, download mode is still working.
Thanks for any help!

Problem with Mi3: rebooting at Mi logo

Hi ppl. I have problem with my Mi3. Before 2 days I installed MIUI V8 6.8.25. Then I installed TWRP and Su, and at the end of the day my phone just started to rebooting. I can put my phone in fastboot mode, but the phone can't load ROM. It's rebooting all time at Mi logo I tried with MIUI V8 6.8.25 beta and MIUI V7 V7.5.1.0 stable (in both cases ROM is installed via fastboot). I can't run recovery with Pwr+Vol Up, just fastboot with Pwr+Vol Down.... I can't shutdown my phone. It's rebooting all time, or I can leave it in fastboot mode. Thanks for any help!
Change your battery. It's always bootlooping at the logo because the board detects something wrong with the battery, and won't even let you boot to fastboot.
I'm having a similar issue where i'm only able to access fastboot and not recovery and it's bootlooping too... Have you find any fix? Please share..
Hi. I solved my problem with batery replacing. Now is everything OK. Thanks for any help

HELPPP!!! Stuck in Bootloop Nokia 8 TA-1004

I would like to ask some few solutions from expert people here. My phone was stuck in Boot loop for no apparent reason and cause. So, here's the chronology: I was playing Vainglory and it was still drafting heroes in ranked match. During that time, the phone just got freeze and unresponsive for several seconds. Then, it restarts and there we go. It starts boot loop cycle. I don't know what causes it.
How do I solve this? I need help, please. The Phone is Unlocked Bootloader and it is in root condition. As for the version, it was using 4.88B. I would require step by step detail in solving this boot loop before i decided to go to service center and have it fixed which is possible to remove Unlocked bootloader and root which I do not want that to happen.
Thank you so much in advance.
PS: After shutting it off for 30 min, I tried turning it back on. It does bring me to the home screen but then few seconds, it reboots again and causes boot loop. Nevertheless the case, once Powered by android logo came, I won't be able to bypass that.
Try to hold Volume up and Power while launching the phone - it will bring you into the recovery mode of android. From there you should wipe your phone data - sorry there's no viable solution for you, if it's a software bootloop then it should help you bring the phone to factory state and get rid of issues.

Sir, It doesn't show the recovery mode. It is like no recovery exist. It just shows Powered by android logo and then keeps restarting.
did you solve your issue? trying to reboot?
How did it happen?
and How did it solved? Did your phone start then?
I think from TWRP you choose to boot different slot.
So I think you have different Kernel-boot to another system-version

Boot-loop Help

Hey, sorry to bother everyone with another bootloop thread by I just can't for the life of me work out if I'm doing something wrong, or my device is more of a dud than usual.
So got the phone yesterday, did some ota updates ended up in a bootloop.
Now at this point my bootloader wasn't unlockable as I hadn't enabled it in developer settings.
By some miracle it managed to boot itself back into the OS after an hour of fiddling and i decided to enable the option in developer settings.
Now I've unlocked the boot loader and got all the flashing related fastboot commands working i've
Flashed a stock image using the miflash tool, seems to succeed but then on reb but once it's done i'm still in a boot loop!
I've been able to boot into twrp a few times (though most of the time I can't and am still in a bootloop)
Tried flashing a custom rom, but I always seem to be in a boot loop after attempting that.
Throughout the last few hours i've also managed to hit the os a couple of times but it seems very easy to accidently put it back in a bootloop.
If anyone has advice of something to try, that would be great.
(was trying stock image version 10.0.9.0, going to try and go back to stock Oreo)

Sometimes it goes to a failed to boot screen, while other times it seems to loop endlessly.

Try some custom kernel, or patched boot img
I've found in 3 Mi A2 phones (mine, gf and family member) the bootloop is actually easy to overcome pretty quickly by waiting. I got the bootloop with all of them when they updated to two updates from what they came with no bootloader unlocked or flashing.
In each case I plugged the phone in, and left it rapidly turning on and off. Make sure to watch the phone, it will possibly come up with an error screen a couple of times so just press to continue trying to boot (also a glitched screen maybe that says fastboot with no options, press the volume control and the option to continue appears again). After a minute or two the phone will get to the normal charging screen, at that point the bootloop is fixed just hold power button until it starts.
Longest I had to wait was coming up to 2m, one time less than 30s.

Yeah, A2 have A/B partition and if update is faulty and the phone ends in bootloop, after a few failed boots, it will boot from other partition.

I think something along these lines is how i managed to get into the phone the first time and enable oem unlocking.
After a lot of playing around I was able to get the phone to boot by flashing the latest Oreo image (9.6.16)
After that tried going to a pie image again from fast-boot image (10.0.8) and once again ended up in a boot loop.
Lastly I flashed a fast-boot image of the latest ota (10.0.10) and managed to boot in.
So phone is at least all working now. Thanks for everyones help. Just hope the next ota doesn't bootloop the phone again.
@NotOverHere: When the phone finally does boot up, do you find it's stable and reboots are fine after that?

Advice: Post TWRP flash/Magisk flash and root, stuck on loop and won’t charge

Hi all. Apologies if I am in the wrong spot or posting incorrectly.
I recently decided to give flashing a go on an old Note 9 as I had upgraded. I managed to flash TWRP properly, flashed Magisk properly and rooted.
‘’all was working fine and my phone discharged and when I went to recharge, it is stuck in boot loop moments after attaching charger and won’t charge. I can get into TWRP and have tried wiping and flashing uninstall for Magisk to remove root, same error. I stupidly didn’t create a backup when previously installing TWRP. I now doubt I will be able to maintain any sort of charge to recover via Odin if needed as well.
any suggestions greatly appreciated
further to this… managed to get it locked on download screen after trying to flash stock rom. Only managed to remove it by reflashing TWRP but still loops
