[Q] Nexus 9 won't boot or even charge - Nexus 9 Q&A, Help & Troubleshooting

Hello everyone,
yesterday I've been using my Nexus 9 with a bluetooth-OBD-Dongle in order to read ECU fault codes of a customers car, using the Torque Pro-App from Playstore.
After this being done, I put my Nexus on top of my desk, bluetooth and WiFi still turned on, with about 80% battery left. Eventually the next day I came back into the office and wanted to unlock the device in order to check my mails, but there was a bad surprise: The nexus did not react on anything I've done. At first I thought the battery was dead due to some wakelock issue, but I couldn't really imagine that 80% battery charge were gone in less than 10 hours. I tried to boot into bootloader or recovery, but nothing worked. The screen stayed black.
Even after putting in the charger cable, nothing happened, no battery charging icon or something else. Simply no sign of life at all.
Currently on CM12 nightlies and Fire-Ice Kernel.
What do you guys think? Shall I wait a few days until the battery is completely dead and then try to charge/reboot it or send it immediately in and try to get a warranty repair/replacement?
Is there any possibility to fix it or do you think that I somehow managed to hard brick the device?
Thanks

@MrSchaal,
I've never seen a problem like this. And (based on the fact that 72 users have viewed this thread), I suspect that no one else knows what to tell you.
So, my suggestion would be to return it for warranty repair/replacement. Good luck.

@cam30era
thanks for your advice, I'll give it a try.

Battery will not charge due to high/low temperature (not a battery defect)

Hey there,
I have my Vibrant for a good year now since it came out pretty much. Last week it just stopped charging out the blue. The battery is completely empty and shows a thermometer with a warning sign and stops charging seconds after its plugged in. So I assumed it might be a battery malfunction and I got my spare battery in as soon as I came home and tried charging - same problem. I think it is highly unlikely that both batteries fail at the same time. Therefore, I assume there is something wrong with the temp sensor in the phone. I saw a few people have a similar problem with the epic 4G, but the discussion got really side tracked by other issues. My phone is rooted, but I was running stock froyo, so that shouldn't be the problem or should it?
I just wanna know if anybody had the same problems and if there is a quick solution, I google and forum searched a while but as soon as you throw in the term battery it gets spammed with battery life discussions.I just checked my files I have on the phone, apparently I have the premium insurance - does that mean I just can go to the next Tmo store and get a replacement? Any feedback is greatly appreciated.

Well for your problem, i suggest you try a different rom and see if the problem persists... maybe its a bug
And as for insurance, you mail the phone in and pay a deductible, which should be like 135$ or so. They send you a refurb.. or if you say it wus lost, you dont have to mail in phone

thanks for the quick reply. Is there a way to reflash without a battery?
I don't see it as a bad thing. If your phone gets too hot and keeps charging that's going to burn something inside. When my phone won't charge I know I have let it down. So it can cool down. But to fix your problem reboot the phone. You can keep charging it after it boots up

As long as your phone can run successfully for a couple minutes, i dont see why not

Mine did something similar. I picked it up after putting it on the charger. It was hot and would not come on. I unplugged it and let it cool off for a while and it cleared up.
I got that message once...
Vibrant was in a car dock, with power.
It was *HOT* out and sun was hitting the back of the unit. (A/C on of course)
Google Navigation was running (display brightness max)
Google Listen was running
Bluetooth was passing music to a speakerphone
When I run the phone with that setup, the charger can't even keep up with the phone power needs. The battery level slowly drops. No question the phone is working hard.
This was a true heat issue... I removed the charger and turned off the display to let it cool off a bit. (I was almost home).
So the question again, is your phone hot or is it a false reading?

Hey,
I am sorry I didn't clarify the actual battery temp. It is normal - so its neither in the sun or in a too cold spot when I try charging it. The phone probably runs for one for a few seconds before turning off so there is no chance of the battery stats wipe. I think I will try to find an external charger and try to charge the batteries this way to have enough juice for flashing a new rom. Thanks for all the replies!
Does it charge the battery with the phone off? If not, I don't think a new ROM will help.
Hey there! Wondering if you got around to solving this. I've got a Vibrant doing the same exact thing. Battery being cool it sais that is overheating. Did changing the ROM solved it or not?

Sorry for resurrecting an old thread, but a resolution never seemed to be made here. Has anybody found a fix to this?
As of yesterday, my wife is having the same issue with my old Vibrant phone which she now uses. It's flashed with Bionix V 1.3.1 and Tigerblood overclock to 1.2ghz. This could be the issue, the Tiger Blood overclock, but I'm not sure. I'm out of the country for three weeks and currently she's left with a dud of a phone that keeps giving her the temperature warning in the triangle when plugged in while the phone is powered off followed by it stop charging. When she turns it on, she gets to the SD card check and then the phone completely freezes. Once in a while it's able to stay on for a minute or so before freezing, but more often than not the phone does not fully turn on and just goes frozen after a few seconds, sometimes at the Tigerblood logon screen before making it to the desktop. Me being 4000 miles away doesn't make it easier to help her but I've recommended she leave the phone unplugged, battery out for the night to see what happens. I also told her to take off her silicon case thinking maybe that has something to do with the overheating. Well after 7 hours of her letting it sit to cool off like that, with the case off, she plugged it back in and is having the same issues as yesterday. Absolutely no progress made. One of her colleagues said she should try leaving the phone in rice confused:) so she's giving that a go and another guy in a phone shop who she went to for advice after work said that the motherboard might need replacing. I'm convinced all it needs is to have the Tigerblood removed or reflash a rom onto it but there's really no knowing unless I have it in my hand.
Is there any quick fix to this problem without having to do all that? Surely there must be a way to charge the phone without it heating up and freezing up. She's tried plugging it into different rooms, on her laptop, etc, none seem to get rid of the temperature problem. I've had the phone since August 2010 and never had any issues with it. I also never once saw that temperature error message so was taken aback when she showed me it over skype. I just upgraded to the S3 and gave her the phone 2 weeks ago, but surely it shouldn't just die out just like that? Thought the Vibrants were made tougher than that?
Any help would be greatly appreciated. Much thanks in advance
Its most probably a kernel issue or a bug in the rom; so the only way to find out is to flash another kernel/rom..
P.s Vibrants are rock solid

Will be looking into reflashing another kernel/rom when I get home in a few weeks time, but it must be noted that the phone has been showing no signs of life for the last few days now. After letting it sit out for 7 hours on the first night, battery out and everything, she went to plug it in the following morning and this time absolutely no notification came up. Not even a lighting up of the phone or anything. No signs of life at all. Every time she hit the power button nothing occurred. The phone still heats up and after a few minutes while plugged in and gets very hot to the touch again but no matter how many times she attempts to turn it on, nothing happens.. She's tried plugging it into her computer via usb, into electric sockets in other rooms, even in the bathroom in one of the 115 volt electric shaver outlets in the bathroom (we live in the UK currently), and none of these ideas worked. Still no signs of life. It has been this way for three days now and is frustrating as I can offer no advice to her to get the phone to turn on anymore.
What on earth can be the problem? Has this happened to anyone before? And is there a fix to this or can we consider the phone to be a paperweight at this point?

Some kernels require a certain amount of power to fully boot the phone up and will not charge until it has 5% battery or so. I personally think her battery may be unable to hold a charge or like I said before it doesn't have enough juice to boot the phone because of the kernel. There is a way to charge the battery with the phone off. You can use ANY kind of usb cord, I used an old printer usb cable when I had to do this. All you do is cut off the side that is not usb and strip the positive and negative wires(red and black), then place the stripped wires on the positive and negative connectors on the back of the phone and insert the battery (make sure it's a snug fit). Plug the usb end into your pc and charge the battery that way, DO NOT let charge for over 2 minutes at a time. Wait five minutes and do it again if you have to. If she gets it to boot up, I would definitely flash a new kernel first to see if thats how the problem originated.

[Q] Phone randomly rebooting, now won't even turn on

So I have the Best Buy Black Tie Protection Plan for my Atrix and about 2 weeks ago I took my Atrix into Best Buy to have them fix a cracked screen, when I got it back it ran fine, then about 10 minutes after getting it I unlocked it and installed CM7 Weekly 4. I started getting random reboots and had to pull the battery occasionally. Then the phone would start to get really hot and the screen wouldn't turn on and the battery would drain overnight when I normally get at least a day off my battery. Yesterday my phone wouldn't even turn on and I found the only way to have it turn on is if I plug it into the charger though it doesn't charge and won't boot, it just freezes at the Motorola boot screen. I can't turn the phone on if the charger isn't connected and as soon I disconnect the charger the phone turns off.
I really love this phone but ever since I got it back from best buy it's been full of problems. Does anyone know what is wrong with my phone or any way to fix this? Also does best buy have a 30 day return policy for when they repair your phone or would having them fix my phone again use up my second and last repair? Thanks for your help, if there's anything information you need to know just ask.
From my understanding, I am guessing that you overheated your phone by flashing a highly overclocked kernel and you also got a soft brick in the process.
My advice to you would be to find another battery to see if you can get the phone to charge and switch on as I think that your battery fried.
Once the battery problem is sorted, you can easily fix the soft brick. There are some threads about it. If you can't find it, P.M. me and I will find the thread for you.
Don't worry, your phone is fixable.

I only use faux123's stock enhanced kernel so it's not that but I think you're right, the battery might be dying from the heat. When I get home I'm going to look up how to charge the battery just from the 3 connectors on the battery and see if that works before I buy another battery. I don't know if that'll fix the problem of the phone not turning on at all unless it's plugged in and then turning off as soon as the charger is disconnected but it's worth a try, I'll let you know.
Thanks for the help!
I actually had a similar situation a few weeks ago.
I had the following set up
-Weekly #3 (CM7)
-Faux's 0.2.1 1.0ghz
-.1.77.30P Radio
I unplugged the phone from charging it (as I do every night) and it went into a bootloop. I honestly hadn't flashed anything new in a week.
I went into recovery and factory reset the device to fix it.
I still don't know what caused this to happen.
My device still overheats quite a bit (gets to ~50 degrees C on the CPU for doing regular things like web browsing). I don't know why it does this.

[Q] Evo 3D doesn't turn on

Hey guys.
I have a problem with my HTC EVO 3D. I've been using it for a year and everything was fine until yesterday. I was playing Real Racing 3 when my phone suddenly restarted and then turned off before I could enter my PIN code and didn't boot up. I thought that it might have overheated or it was some crash or something, I put the phone to charging and it easily turned on (I must mention, that there were about 70% battery left). I charged my phone and didin't use it whole afternoon. In the evening, I was trying to unlock my phone (with about 70% of battery) when suddenly the same happened again - the phone restarted and before entering PIN code turned off at all. After that I wasn't able to boot my phone.
I tried charging it with original HTC AC charger and also using my laptop and even a car charger, but nothing changes.
When the phone is not plugged in to charging, it doesn't show any signs of being alive. I tried pressing volume down/up/camera buttons + power on button, taking off the battery for about an hour, charging the phone for ~6 hours. Nothing works.
However, I realised that when I connect the phone to my laptop, there is a 'new device is connected' sound, but I am not able to access my memory card or do something else. Also, when the phone is charging, the red charging light is on, which after a few hours turns to green and after some more time disappears at all. When trying to turn on the device while it is charging the red light disappears as soon as the power button is released ant comes back after about 20 seconds.
Sorry for such long story and for my bad English. I am very disappointed. I still have a warranty, but I dont want to take the phone there, because the fixing lasts at least 2-3 weeks and also since I'm unable to boot my phone, there are a lot of my personal information in it, such as passwords,messages, bookmarks and so on, left.
So, is there anything I could do or should I take my phone to service?
P.S. The phone is not rooted and never was. Everything is original and up to date.

Perhaps try a new battery or take it in and have them try one. Sounds like a battery issue.

Thanks. I took it to service. I hope they'll repair it.
I finally got my HTC back a few days ago. They changed the motherboard and I had to buy a new battery since the old one was dead and warranty for it was only a year.
But I've faced several unexpected crashes during these few days. I think 3 or maybe 4 times when I took the phone after not using it for couple of hours and tried to unlock it, the phone didn't unlock and instead turned on. I really don't like this, because if my phone turns off whenever it wants, I may be unreachable
Does anyone knows what that means and what should I do if this keeps happening?

Yes, the soft has always been and is stock.
Then it must be a hardware issue. If your warranty has not expired, take it to the warranty service.

Well as I said I dont want to take it there because it takes about three weeks or more till I get back my phone.. It would be the third time in two months and it really annoys me.
Couldn't this be software issue? I mean I've been reading some similiar threads and I found out that some app might be killing the phone. So I did hard reset yesterday and after that installed only well known essential apps (Google services and some others) and after that the phone didin't crash for almost two days. Unfortunately, it did turned off a few minutes ago. I've installed only 8 Ball Pool and Smart Keyboard Pro recently, so I will try unninstalling them both and let's hope the phone won't crash again. Is there any ideas what else may I do in case it doesn't work?

Id recommend doing a factory reset on the phone and not installing any app for at least a week to confirm its not a hardware issue, but I strongly believe it is. If it fails youll have to take it to a sprint store and hope the clerk is in a good mood and give you a new phone the same day.
try a new battery
The battery is new, I had to buy it only a week ago, because the service stated that the old one was dead.

Battery problems and early shutdown? give this a try!

Hi people, nexus 6P owner since 2 years now. I remember when I received the phone I could reach without worries 5 to 6 hours of Screen but then, after nougat and now Oreo, I've never achieved again that numbers.
After rooting my phone, flashing carbon rom and installing elemental X kernel, I played with governor profiles and improved my SOT a little over this year but it was getting worser and worser by every day (2 to 3 hours of screen on time and heavy idle drain). Finally, the real problem came the other day when for the first time my phone shutdown at 29% suddenly after opening the camera.
So I read internet and found in the nexus 6 (not 6P) forums that someone suggested a solution concerning a problem with how the phone meter the battery remaining, suggesting doing a series of steps of charge discharge that I will list here. This, and changing to ABC rom may have done the trick, as now I'm getting much more normal battery life (considering the degradation of 2 years, 2700mah left approximately) of 4, 4 and a half hours (yours will be better) SoT and an idle drain of less than 0,5% per hour, and apparently it didn't shutdown early anymore.
So, give this steps a try if you tried everything like I did and you still having problems with battery drain.
STEPS THAT MAY SOLVE EARLY SHUTDOWN PROBLEM:
- Charge your phone to 100% and use it until it shutdowns (look at what percentage).
- Boot to recovery by pressing power and vol - button, and once in there let it drain the battery until it shutdowns by itself (may take a lot of time so increase brightness to maximum in the recovery menu under settings to consume it faster).
- Now it has really reached 0% and if you try to power it on it won't let you by blinking red in the notification led.
- Plug the charger and leave the phone off until the battery indicator show it's full.
- Unplug it and turn it on, it should show you the battery at less than 100%, like 95%, 90% or even less depending on how bad it was calibrated (mine showed 95%).
- Plug it to the charger without turning it off until reaching 100% and only then unplug it first and then turn it off quickly.
- Plug it one more time (off) until the icon shows it is full and then unplug it and turn it on, now it should say a number closer than before, like 98% or 99% (mine was 99) or it may be 100%. If it shows 100% then you're good to go with the calibration, but if it shows less, repeat the process by letting charge until 100 and then doing the same steps as before until you turn it on without charging and finally it shows 100% battery.
Please report back if this steps worked for you, because for me I think it made the trick.
Now for the battery drain what I did was this steps,
STEPS THAT MAY STOP THE POST-NOUGAT HEAVY BATTERY DRAIN (android OS drain, etc):
-Unlock and Root the phone
- Install ABC rom (check the post here in XDA)
- Flash ElementalX kernel (also here)
- Install the app "ex kernel manager" from the play store
- Enter settings and disable printers (you still can enable them if you have to print something)
- Install Greenify from the play store and select all the apps that don't use notifications.
- Uninstall unnecessary apps that you don't use anymore.
- In the Ex Kernel manager app go to CPU -> governor options and select "load". Choose one of the following recommended profiles: Excalibur V2, Dragon Fly v1, Butterfly or DeadPool. (Or check the guide in XDA about governor profiles).
- Finally activate the run on boot option and reboot to recovery, wipe dalvik and cache and then boot into system.
If you have luck like me, your phone will run very smooth and battery life will be normal to it's current degradation. My phone now last me all day like before and I don't have to charge it twice or three times like I did and best of all, when I don't use it, it almost don't lose battery (2 to 3% overnight).
Also I've never seen again that android system process consuming the same amount as the screen!
I hope this serve someone and maybe save some phones too , I never resigned my 6p because it's a great phone with one of the best cameras out there even today and with great speakers too.
Please let me know if it worked for you! Of course I don't promise it will, but you have nothing to lose anyway! Good luck.
Pd. Sorry for my English , I'm from Argentina
UPDATE: Today my nexus shutdown at 10% but only because I opened on purpose the camera to check if that is the problem, and aparently it is. I've read that when then phone has low power, an app that consumes a lot of battery like the camera may cause shutdown to prevent the phone damaging internal components. So no fix for that at the moment, just don't use the camera with low percentage.
Hi, I don't know if this thread is still on but I'd like to say that I had the same issue. I have a Nexus 6, as you said, and I've installed on it the Resurrection Remix ROM (Neo version). After that, the phone suddenly shut down everytime it reaches 20 or 30 %. I tried two solutions they suggested me;
1) In bootloader menu, go on bootloader logs and press start button for 10 seconds more or less (when you get Google logo and the phone actually boot)
2) Try to reboot the phone in Safe mode and then back in Normal mode
I've also tried to calibrate again the battery (maybe I did it wrong); I followed a guide on it but I can't remember every step of it (if interested I'll try to find it again). Nothing worked, the phone still presents the same issue and I really don't know what to do. I'd like to try this too hoping it works otherwise the last thing I can do, I guess, try to flash again the ROM. Do you have any suggestions? Thanks so much
P.S.
The battery works PERFECTLY; before I flashed the ROM it worked so damn good so I really can't believe that it needs to be replaced, I know that the phone is really old but it always worked fine so it's more logical presume that the problem is with the flashing
Using Stock Nexus 6 Shamu Kernel, with last TWRP and RR OS
Just replace your battery - you might think it's the flashing etc, but at the end of the day my money is on your battery just having called it day, which they can do quite suddenly.
I found that once that early shut down starts it gets worse quick.
It's not that big of deal to change out on these phones anyway and if you do it yourself it's cheap (15 dollars or so). - I've just done it for the second time, not that I was having early shutdowns with my first replacement but after about 18 months life was starting to wane.
Just sharing my experience with my nexus 6p.
Early shutdown problem sure gives us headache. Already tried several methods like calibration, reflashing to factory images, downgrade to minor build or major build, none of them works.
The only solutions that works for me is replace the battery, only cost between $10 to $20 for me (it depend on type battery that you buy, mine is OEM one)
Hello, giving a try to the OP guide regarding early battery shut down. Just a quick question - how long does it take for battery to drain out while in recovery mode? Screens been on for like 2hours now, I see top right screen corner the battery % completely disappear, but recovery still usable. Just wonder, how long it will take for phone to auto shutdown while in recovery mode?
And if this does not work, I'll just replace battery, like @reintakura wrote above.
This device is a disaster. Does it really work?
I tried this the other day. The phone shut off when the low battery came on. I kept powering it up. The first few times it shut off immediately. The next time it turned on and said I had 10% left. Let that 10% run down, it powered off. I kept powering it on... it would boot. I did this maybe 50 times, every time it would boot and then shut down. Then the last time it got "stuck" on the Shutting Down screen. I let it sit like that for a good 10 minutes. It never powered off, it just was stuck on the shutting down screen. I held the power button down to initiate a hard shut down. Plugged it into the charger, device off. Screen said it was 100% a few hours later. Turned on device, device reported 100% used it until it got to 70% and then the low battery light came on and it powered off. Let it charge overnight with device off. Right now it's slowly losing battery, I'm at 76% and it hasn't shut down.
Strange stuff going on.
i was facing the same problem, two days ago i returned to 8.1 abc rom
i'm getting 4h sot and no early shutdown
I can't believe I spent $200 on this **** phone and waited 3 years to get it thinking its the best thing since fried rice, mine started shutting down at 20-30% now it shuts down anywhere from 30-85%!!!!!!!! ahahahahahaha in the end its my fault for buying refurbished, someone obviously sent this crap back already and they did nothing to fix it and conned me into buying it.

Hi, there. This reply is way late, but I've been away for years and I've only now decided to come back, so I'm necroposting on everything that's relevant to me right now. I hope that's not a serious offense.
I've had my 6P since August 2016. I bought it NOS from Google Fi at a slight discount. It worked like a charm for me for years until around winter 2018/2019, when it started shutting down in the cold. I figured that was understandable. I bike a lot, even in sub-zero temperatures, and I tended to keep my phone in the breast pocket of my windbreaker.
It didn't care too much for that.
So, I started putting it into my backpack and it stopped shutting down.
Then, this summer (2020), the battery went off a cliff. It's been dying anywhere from 80 to 10% since June. Maps and the Camera are the big killers, but the battery will plummet from literally any use.
Yet, it will idle for days if leave it alone.
I recently decided to just wipe the thing back to factory and see if that solved anything. It was quite a feeling to scuttle all of my SMS (I backed them up to my Google account, but it seems like they've gone to some mysterious corner of the Internet from which they cannot be retrieved. Alas). It was kind of a catharsis to throw it all away.
I did back up all my media, however.
The factory reset solved nothing, so I tried the OP's recommendation. I loaded into the bootloader and, instead of waiting on the primary screen, I went into (stock) Recovery (my phone isn't yet rooted) and ran the display test a bunch of times. I alternated between that and selecting "Barcodes" since the all white screen is a bigger drain on the battery than the black and green default.
Eventually, the thing died, but it took hours. This, despite that it would die at the snap of the fingers when in the OS. Strange. I charged the device while off until it said it was full. It came on at 95%. I followed the OP's guide until it turned on at 100.
Yet, it still started draining immediately.
The current culprit is "Mobile Network Standby," which is rich because this phone has no SIM, so why is it even bothering to try and futz with the mobile network? I had been keeping the device on Airplane Mode, but I'd forgotten to turn it back on. I just reactivated that mode, so we'll see if that helps.
However, if I watch a guitar repair video on YouTube (pretty staid, not like gaming or an action movie), the battery just nosedives again.
I don't think that rooting and flashing a new ROM is going to solve this issue.
I bought a replacement battery. I'm just not eager to try and install it. So I may just try root and flash, since it's easier. I guess we'll see what happens.

your battery is probably aged, I got the same problem and replacing battery is the only solution that'll work.

I reckon that you are correct. However, I am noticing that my phone hasn't crashed since I followed the OPs charging guide. That's something, at least.
Although monstrous battery drain is still a huge problem. I will be swapping the battery.
My question is: root first and flash something custom, just to see what happens? For evidence gathering ... in the name of empiricism.
Or just go ahead with the swap before doing anything else?

yeah try root and installing ABC oreo ROM if that doesn't make differ at all then replacing battery is the only solution.

Poco Pixel 11 Plus Rom Loop Wont switch on

Greetings,
I have been using my poco f1 for 4 years now and it has stood by me strongly. I only replaced the battery once due to excessive usage from covid (hotspot on almost 12+ hrs of the day).
It had pixel plus 11 rom in it and I was very happy with it too. Over the past 1 week, i noticed it was behaving strangely.
1. The charge time took almost 3hrs even though it showed charing rapidly
2. When I switch off the phone and keep it for the charge, it charges comparatively faster.
3. At certain times, it would freeze and restart.
4. Would heat up during charging, so I would keep it near a window or anywhere there is a breeze so that it doesn't overheat.
As of yesterday, the phone went into a complete loop after charging (It was off while being charged, once it reached 95% I unplugged and switched it on) with poco symbol followed by the 'G' icon appearing.
I thought i'd wait it out, but no luck. The weirdest thing was, when i reconnected my charger (Charge ON), it would switch on. And when i'd unplug it, the phone would switch off and go back into the loop.
The phone was near full charged, but i figured this is probably a rom issue and needs a good flash. So, I plugged the phone in for charging again so that I could switch it on and then took the necessary backups.
In parallel, I downloaded the latest rom (Pixel 12 stable build) thinking that if i flashed it would solve everything.
I connected the phone via USB to the laptop to copy the rom file, but it didn't swith on. It would only do so by charger. (Weird!). I tried it a couple of times, and managed to switch the phone via USB cable connected from laptop. But it didnt last for long as the phone would switch off shortly. Fortunately, it was on for just enough time and i mean, a couple of times till I could copy the file into storage for flashing.
I reconnected it back to the wall charger, switched on and took backups. At this point the phone has reached 100% for about 2hrs or so, but there's nothing i can do in order to get it to be on.
I proceeded to flash pixel rom 12 via twrp after clearing the cache, davlik and all of that. It was successful (no error messages appeared) and when i rebooted it I could see that the rom went through fine as the charging '100%' icon has changed (Its more graphic) but the phone still wont switch on and continues to be on this loop.
Can anyone please advise me on how I can tackle this? I dont want to buy a new phone as I feel there is nothing out there that would match this phone for its value. (I can use pixel rom, good battery, durability)
Any help in this matter would be highly appreciated.
I'd be more than happy to make a contribution to anyone who can provide me with a solution that works. I'd rather be happy with my old phone and you can treat yourself to a nice meal rather than having to buy a brand new phone. (So far, im looking at mi 11x, s20 fe, mi 11 lite, oneplus 9R, but to be honest they just don't appeal to me. You know what they say, once you go poco, you go loco!!!!)
Thankyou
Be safe

Firstly make sure you followed this installation guide.
Then if you are sure that flashing is correct, I think it's your battery issue. You should replace it.

Hi there!
Thanks for replying!
I tried the same out all day yesterday and had no luck.
I have given it to a mobile repair shop nearby (we have a separate market for mobiles here).
Hopefully they can sort it out or else I'll go for a used S20 FE 5G, saw a couple of them ranging from $300 - $400

You could just buy and replace the battery by urself with 5min YouTube video
In repair shop they may ask extra money or try to show u that needs more than battery.
I am sure it's battery tho.

Hi there!
Thanks for replying. So, my phone did get fixed, apparently, the issue was due to the charger port and battery connection. Somewhere there was a short circuit causing that issue.
They mentioned this happens due to overcharging or using the phone when on charge or running heavy applications.
Yes, a battery replacement would add a few more hours of battery life I'm sure as I currently average 6 hours on heavy usage.
I plan to use this phone till it no longer runs as the alternatives out there arent really all that great with respect to value for money and reliability. I hope to get my hands on the mi 12x, it looks really appealing!

I am glad you found the problem and you got it fixed
For sure hardware of POCO F1 is still good and worth the money. Enjoy the paradise of custom ROMs
