here's what else I've done to resolve my issue (as seen on XDA): Hoping someone on this thread may have other suggestions.
-Boot into recovery and randomly pressing back and menu button for a few
(worked for the next little while)
-*#*#2663#*#* and update TP Firmware and tried updating both too
(again, it worked for the next little while)
Now it seems to be worse. It just doesn't work at all. Reboot, battery pull and retrying the above now doesn't work.
Went from a Stock 2.3.3 (rooted) ROM and tried Lite'ning ROM. Of course, factory reset after flashing custom ROM but that also would make it work for the next little while too.
Any suggestions??
^bump
anyone else have this problem? I just flashed back the Stock kernel and firmware that is for Three UK and factory reset. Same problem.
I guess no one else has experienced this issue...I got me a lemon.
I spoke with Samsung and they'll be fixing it for me under manufacturer's warranty.
Hello XDA! This is kind of long winded, but I'm at the end of my tether with this and all I want is a functioning GS2 back in my hands!
I have an international GS2 that i've owned since they appeared in the UK. I rooted it after a month of running stock and then started flashing ROMs pretty soon after that. I have flashed many many ROMs, all with success and no issue whatsoever.
However....
I now have a GS2 that boots into recovery, boots into download and will boot into a ROM. Once booted into a ROM, it will freeze, either instantly or after a period of minutes. The screen becomes non-responsive yet the ROM seems to function, calls come in and continue and it still connects to a PC to browse storage etc.
I've wiped and flashed a multiple of ROMs - CM, RR, PA, multiple official stocks. Followed all the install instructions as per usual. Never took any shortcuts or whatever.
Inbetween all this the power button stopped working. Took this to my local store, they showed me the water damage, they replaced the button and that was rectified, working again.
So....basically no ROM would work properly at all. I assumed that this was a soft brick of some sort and gave up hope of getting this fixed myself. Took it back to the phone shop, explained the issue and he said it should be repairable, good chance it was just a software issue and that if worst came to the worst it would go on the JTAG and be flashed back to stock and I would lose everything but have a working phone.
Obviously the phone was picked up today and it's still the same. Boot into stock ROM and pretty much freezes instantly.
The phone shop dude said he tried a new screen to see if that was issue, it wasn't. They tested all the connections on the board and there where no shorts apparently. They had it on the JTAG multiple times, that didn't fix it.....
Doe's anyone have any idea what could be the cause. Do I just let it RIP or is there a chance someone out there can fix this.....
Thanks in advance and sorry for the rambling post. I thought I better lay out all that's happened with the phone and the work that has been carried out on it.

Did they check the battery?
I assume they did.
Nuke scripts can clean all previous ROMs leftovers and format system will get your device all cleaned up.
If those 2 don't work, hardware it is, swap shops and see.

Could be a GPU issue. If it is then you will need a mobo replacement or replace GPU if possible.
Alternatively you should do a complete clean install or rom which means make sure all the old files and partitions are cleaned before installing a rom. First simply try using a rom/kernel cleaning script and the flash custom or stock rom. Another way would be to format internal and external sd cards via CWM and then flash rom.
If you still have issues after doing above then you have a hardware issue and will need new mobo.
Hello,
I am encountering a strange problem with my new Redmi Note 2, purchased from Top One. Whenever it is off and the battery is in, every 30 seconds it will vibrate and momentarily flash the white Mi logo as if it is about to turn on, then it will go back to black, then do this again in ~30sec. I have tried removing the back of the phone to see if it is an issue with the power button but it continues to happen whenever the battery is in. If battery is removed for ten seconds and then put back, the issue stops -- but then as soon as I turn the phone on, and then power off, it starts again. Otherwise the phone seems to run normally.
I flashed it to Miui 7.2.2.0 global stable Rom immediately after receiving it, and the problem has been there from the start. I believe I had noticed it there even before I flashed the new rom but I'm not sure as I hadn't yet interacted with the phone much...
Any suggestions? If you could please give me your instructions as basically as possible, and for Mac, I would appreciate it as I am a newbie. I flashed the rom using my Mac following instructions from the MIUI forms that showed how to do it in terminal after installing "adb/fastboot."
Thanks!
Seems to me that it is going into bootloader mode, instead of powering off completely. I am not sure how this could have started - perhaps a partially failed ROM upgrade at some point. I think you should return it (after restoring the original ROM) because trying to solve the problem might have to involve doing some low-level and extremely risky stuff.
Or for some weird reason the buttons get stuck and restarts to recovery.
When you try to boot into recovery, you get black screen->vibration->MI logo, and if you continue pressing the buttons you repeat the pattern.
Remove the battery cover and check if there's something in the buttons for a start..
Thanks for your responses

Could you give me a sense of what the low-level/risky stuff would be? Is it something I might be able to get done at a phone repair shop in the UK (where Xiaomi of course is not sold)? I ask because I'm required to pay for return shipping to China if I'm going to return device, and god knows how long the whole return process will take -- so if it's not a major hardware issue it might be worth it for me to explore finding a fix.

I don't see anything unusual in the buttons. As I said, if I remove the battery for ten seconds and then put it back in, I don't get this problem. It's only after doing a successful boot/shutdown (which works normally) that it starts again. So as far as I can tell it doesn't appear to be a mechanical problem.

The low-level+very risky stuff would involve flashing a full ROM. By "full", I mean inclusive of preloader, uboot/lk, etc. This is what makes it very risky, because if something goes wrong with the preloader/lk flash, the device could be bricked beyond what normal people could recover. An example of a ROM that flashes everything is: http://www.needrom.com/download/miui-7-2-3-0-redmi-note-2/
My current ROM is based on an earlier version of this, and I noted at the time it was released that it installs a preloader - but I am not sure whether I installed it complete with preloader or not (I probably did). From what I can see, nobody's device got bricked by installing this ROM, which is actually excellent (so much so that I inevitably return to it after trying something else). However, it is still risky to upgrade a preloader. I suspect that this may be what you need - but it may not resolve your problem anyway.
PS: beware of more recent Xiaomi ROMs that lock the bootloader. If you tried to do this risky process, you would be best advised to make sure that you are not flashing a ROM that locks the bootloader (i.e., the most recent ROMs coming out from Xiaomi).

Thanks for this. Could you point me to how I might be able to install a full official Xiaomi rom? (One that won't lock the boot loader.) My preference would be to get the global stable rom running as normal so that I can have the standard working phone with OTA updates. Or, is it easier to install this rom you've suggested with preloader, and then afterwards I can flash the official rom (assuming this fixes the problem)?
Also, are there any tutorials/clearer instructions for how to do this kind of install? The instructions on the link you've provided don't seem very clear...
Not sure if I'm gonna try this yet but leaning towards it if I feel confident enough I can execute it without screwing anything up...

I personally wouldn't touch official ROMs with a bargepole. At the very least, xiaomi.eu, or ROMs based on it (like the one linked to). But each to his own. With regard to installation, I don't think you can get more detailed instructions than those given, which I will now try to present in clearer English:
Reboot to Recovery ( TWRP only )
Wipe Dalvik/Art
Wipe cache
Wipe data (note that TWRP allows you to do 2-4 in one go - they are the same as resetting to factory defaults)
Install ROM
Wipe cache and Dalvik/Art again (but do NOT wipe data)
Reboot
Wait for about 20 minutes while it builds Dalvik/Art, and other stuff
Done
Hopefully, this will cure the problem. If so, then you can install whatever ROM you want, following the same process as above. If not, then you still have an excellent ROM anyway.
By the way, doing any of this presupposes that you have already installed TWRP recovery. If not, then that is the first thing to do.

Thanks for the English translation haha, I'll give this a shot. Just one more question -- when you write "install ROM", I should just treat the ROM the same way that I would any other, by flashing it via fastboot (as I did in OSX terminal) right?

No. Steps 1 to 7 inclusive are done from TWRP Recovery.

Well, thanks again for your suggestion, but unfortunately it didn't succeed. I managed to install the custom full ROM you suggested with TWRP, and the problem persists; when the phone is off, I get this strange problem with the Mi logo flashing.
I'm investigating how to make a return, but I thought I would ask: do you have any idea whether this problem will negatively affect the phone in any other way? Because, if I'm unable to make a return, I think it's an issue I can live with (I rarely have my phone switched off anyhow), so long as it won't cause more problems down the line...
Something else I just realised: Apparently the problem doesn't occur when the phone is plugged into the USB (both electrical socket and computer). Starts up again as soon as I remove the plug. Perhaps that provides more context...

Well, I would hazard a guess that this is not a software problem. Clearly, the phone is trying to boot into bootloader mode or into recovery mode when it is meant to be completely switched off. This implies;
a) that there is a possibly a hardware problem somewhere (eg., something short-circuiting somewhere?), or
b) a virus/rootkit trying to dial home?, or
c) some other unknown fault?
None of these options would give me any peace of mind. If the problem is (b) then a good anti-virus or rootkit remover program would solve the problem. Search the PlayStore for those. If that doesn't solve the problem, then it's either (a) or (c) - and that is not good.

Nothing shows up on anti-virus/rootkit. I guess I should really insist on getting a return. Hopefully they will process it without too much fuss/expense. If any other suggestions come to anybody in the meantime, I'd be glad to hear them.
I just noticed as well that someone posted with what seems to be the same issue to mine last year: http://forum.xda-developers.com/redmi-note-2/help/phone-rebooting-shutdown-t3232941 , with no resolution. Perhaps this is some kind of occasional manufacturing problem.

HW problem: Power Management IC
I too faced this problem and I suspected Battery to be the culprit . Anyway , i got it checked and repaired at a local (non xiaomi) repair shop that claims it was the issue with PMIC power management IC and that he has replaced the IC .
Now the phone works fine and does not enter into that bootloop even when charger is disconnected and phone is rebooted manually. I hope the problem is resolved .
However , the other issue is still persistent which is : copper colored washed out MI logo constantly appears on the screen and reinstallation of sw did not help either . In india these repairmen usually cant explain the problem area if it is outside of "Try and test" scheme .
I spent 1000INR to get it repaired but I highly doubt that PMIC is replaced. Coz this repair guy did this replacement in just 6 work hours. probability of getting the right part at right time at his disposal is very slim. And I had seen his workstation once, where i di not see any SMT repair station either. Which means that he cannot replace BGA package IC at all. Anyway, I will receive the phone tonight. Lets hope it works fine and the other problem gets rectified by flashing.

Long story short, stock phone just randomly blew up and I'm trying to re-install its stock Android OS. Phone has never been rooted before, it just started to reboot on its own and now I'm in a position where I can only access download mode.
I'm in Odin, with what I believe is the correct firmware for my device (SM-N950U1) and I just keep getting a "Secure Check Fail: system" when trying to flash. it via Odin. The Odin log says "FAIL! (auth) right after trying to write system.img.ext4 for a few minutes. The "Secure Check Fail: system" is the printout on the phone screen itself.
Any clues?

Nope, I have not solved the problem. I've scoured the internet and other people asking the problem all have not had any answers either. My assumption is that the actual internal memory of the phone is corrupted and won't let me write past a certain point, or on certain sectors, or something and its not actually fixable via software. I think everyone else just stops at this point and its never resolved because there is no resolution hah.
Good luck, let me know if you ever figure it out...

This phone I am working on is for a customer of mine. Thankfully, they have given me an open ended time frame. I have been working on this for about a week trying to figure out whats going on.
The memory corruption thing you were talking about resonates with me, because prior to my customer bringing this in, they had attempted a couple factory resets trying to resolve the original issue which was all the system apps crashing. The phone would reboot like someone killed all the processes. Pretty much from the moment it reached the home screen, and it was not power related. The problem persisted after their factory resets within recovery mode. And then I hit the phone with Odin and ended up with a partial flash. Soft bricking the phone.
You saying that kinda reinforces what I was already thinking, that it might be a hardware issue. Im not sure.
5 minutes ago I was able to get odin to successfully flash BL, CP, and CSC. It even brought me back to the Samsung logo for a minute but hung there. That's the most success I have had with this thing. Ive flashed numerous firmwares and every single one of them fails on system.img.ext4. After it reboots, it boots directly into this altered version of download mode with an emergency recovery error.
I have flashed dozens of phones before without issue. This is the first time I have ever experienced this one. You could be right but I refuse to accept defeat in this case lol so im gonna keep trying and ill report back if I have success.

Man, that sounds very very familiar to mine. I don't know if you found my other threads where I was asking for help, but I woke up with a phone that wouldn't turn on. Finally found the key button combo to get it to soft reboot, then it would turn on and just crash in the middle of using it after anywhere from 30 seconds to 5 minutes. If i started to use the phone heavily it would just shut off instantly and reboot back up on its own.
After clearing the boot cache, then doing a factory reset, it finally just stopped turning on at all (just samsung boot logo loop)
So I hit it with odin, unsuccessfully for 2-3 days, and then out of nowhere it just finally took a successful flash. However, it still just bootlooped, so I did a factory reset again and it put it back to being toast.
Since then, not a single successful complete flash from odin. I too can do the BL, CSC and CP files but I can't flash the AP file as it is writing the most data and finally fails about 3-4 minutes into to writing the system image file.
Again...good luck, ha!
Hello everyone,
I hope everyone is keeping safe during these unprecedented times of Covid-19 (In India, things don't seem to be as good for now. Shall get better soon, hopefully!)
My A50S SM-A507FN is frequently getting restarted automatically since a week now. I have tried the basic steps like clear cache, factory reset etc. both from the phone settings as well as via hard reset menu, to no avail. It may be due to firmware or could be due to hardware issue (power IC maybe). I have seen a lot of A50S owners reporting same issue on Google, etc. but no concrete solution. People have mentioned that upon taking their phones to Samsung Service Center they are suggesting it being due to motherboard issue, and suggesting to change the motherboard @ INR 8000 which is insane IMO. I am thinking to flash the custom rom on the phone, as it may probably overrule the firmware or the laggy OS lag due to which this problem is occurring. Also, if the problem persist after flashing the rom, it will give me clarity that the issue may exist in the power IC indeed, and is not due to software. The only confusion though is, whether it's safe to flash the custom rom, considering the issue of sudden restart. I wonder if the phone will malfunction and restart in recovery mode too, for its not being operated via OS during that time. What if the process gets interrupted due to phone restarting during rom being flashed. It should not brick the device, right? At max I will have to boot the phone in TWRP mode again to flash the custom rom file, right? I used to flash custom roms a lot almost like a decade ago when I used to own HTC smartphones, but its been a while since I do this, and hence the doubts.
Please share your inputs, I will highly appreciate the same.
Thanks in advance!

Hi. Did you get any solution for A50S restart issue? I am facing the same. Did you try custom ROM or changing Power IC?
