Need help rectifying my phone !!! - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

So here the deal guys , my mi 9t pro is about a 18 months old and recently started to have issues with battery life (long story and since I wasn't personally using it I can't explain the issues very clearly but it was all over the place doesn't charge at times verified the charger was indeed charging another phone , sometimes the phone turn off when the charger is connected so quite a lot of erratic faults and no consistent issue to point out )
I have been trying to look into it for a week now and this is my observations.
So first and foremost the phones does not turn on ,meaning that when just the power button is pressed it is stuck on the boot screen with just mi displayed on the screens and does not change at all even after hours.
I did find a way around it when I send the phone to recovery mode by pressing the volume+ and the power button and then selecting reboot and reboot to system. This way the phone always turns on . How long it remains on is a different matter some times it a few secs while at other times it could up to 10 mins and most of the time if its plugged to a charger and I disconnect the charger it immediately turns off.
Things that I have tried
Firstly, I had suspected the battery but on opening the rear cover realized that the previous battery looks in extremely good shape additionally I connected the new battery but connect the cable and realised that the fault persisted.
Thinking it was a software issue I also tried to flash the latest MIUI version from its official website with no help.
Now I am certain the issue is with the circuit or with the motherboard.
Any previous experiences and how it was fixed could be helpful .I don't mind doing some troubleshooting myself and can arrange for advance tools if required.
In short would appreciate advance level help as I enjoy fixing these things myself.
TL;Dr my phone is behaving quite erratically and having tried the battery and software need help repairing it.

Did it flash without issues? And how did you flash it, which tool? What variant of phone? And what rom version did you flash?

[Q] Hard-Bricked G1

Hi there,
I fear I hard bricked my G1 (after long years of good service as gps device thanks to a 2600mAh battery).
Since it was quite slow on CM7, I downgraded it to CM6.1. But this would'nt boot. (boot loop)
So I did a bit of reading and decided to downgrade the radio too. I downloaded a flashable zip and flashed it the usual way in the CWM recovery - which didn't finish (after a few minutes), so I removed the battery.
Since then my G1 wont start any more. On top of that, it want event charge. If I try to charge it the status led wont event light up. (I already tried it with two different batteries, both yield the same results.)
Funny thing though: If I don't charge it and let it sit for a few hours, the status LED very shortly lights up when pressing the power button. (But other than this nothing happens and if I press the power button again shortly after the LED stays dead.)
So ... I fear the problem is hardware and not software related.
Does anybody have an idea what could be broken (software or hardware) and if it's software based if there's a way to revive my phone?
(Before anybody asks ... yes, I have newer android phones, but I really live my G1 for nostalgic value so if there a way to get it running again I definitely would try.)
thx a lot,
Bapf
Sounds like you need JTAG, and don't take this the wrong way, but flashing firmware isn't the usual way, its the way you brick your phone. If possible always use fast boot to flash firmware or you are asking for a brick.
You can buy the JTAG equipment yourself and the software is free. Or you can see if you can find someone locally to do it. Unless you have a particular sentimental value to this phone it maybe cheaper to buy a new one.... Sorry for bad news

Bricked G1 - Try Again w/ SIM Card IN!
I had the exact symptoms mentioned in this post - tried nearly everything until I finally put back in the SIM card (even through I don't have T-Mobile anymore) - it booted again and registers the AC adapter and/or USB cable. Hope this helps some who are struggling at this level as I did!!

I don't know if this will work,as I've never encountered a situation such as this, but have you tried bootloader(power button+camera button)?
If you can get it into bootloader, then I have the original rc29 DREAIMG.NBH file(plus, rc29 is the best place to start if you want to root it or install a custom rom).If you get it working and just want stock 1.6, i have those updates as well.
(all said out of hope, I have a g1 and I love it,I'm really glad that someone else shares my enthusiasm!!)
If bootloader works, give me your email and i'll send you the files, good luck!:fingers-crossed:
Nope. It won't even start the bootloader.

Well thats unfortunite, I guess it's just for a soft brick.

[Q] A very strange rebooting problem.

Regarding: Samsung Galaxy S3 Mini GT-I8190 - SIM unlocked version
Hello eveyone.
I'm having one of the strangest problems I've encountered with a phone before and I just can't seem to track down the problem. Please read this thread with an open mind as from what I can tell this is a unique issue that sounds like normal issues.
The main problem is that the phone keeps rebooting. From the get go this sounds like a normal issue with either the battery or power switch but here is the weird part...
It only happens when the phone is fully charged!
IBackground
I have had the phone since release and I have only ever used the stock rom that came with the phone. I don't really use phones much n general except for using it for calls texts and BBC news. I didn't even have a SD Card in it until after the problem started. Everything was running great, I never had any battery problems at all, and then a couple of weeks ago my phone contract expired with Orange and I decided that I would get a SIM only plan with EE.
While waiting for the SIM card to arrive in the post I charged my phone up one day and noticed that I had to power on the device. The phone seemed to power on fine, I could use all features of the phone, but when I turned the screen off for more then 5 or 6 seconds the phone would restart. There would give no indication that it had turned off or that it had powered off in anyway. It would simply just be blank, I'd press the power switch, and it would vibrate once and begin its start up procedure as if it had been turned off completely.
Here is where it gets weird, the phone will keep cycling on its own like this until the battery drains itself through constant reboots until about 85% juice, at which point it begins to operate functionally.
I heard that some people say they had problems with the power switch. I figured that if it was the power switch it then the problem would be consistant and would continue giving me problems when the battery was below 85%. I think I can rule out the power switch as faulty. Naturally I came to the conclusion it must be software, perhaps an APP installed which was incompatible. I tried all sorts of things, regardless I came to the conclusion it needed to be factory reset. Factory reset didn't do anything, still does it. My next thought was Firmware, it must be the firmware that was corrupt. I went through tutorials and rooted my phone, installed recovery software and ended up installing Cyanogenmod 11 (Which looks really beautiful btw, wish I had done that sooner) and buying an SD Card too do so. Still the problem persists! I read that some people had problems with swelling batteries, I replaced the battery completely just incase. £10 wasted, still does it.
At this point I'm starting to get confused. I started thinking perhaps it was the cable providing too much charge to the device, over charging somehow. Tried a different cable and a different power source. Still the poblem persists. I made sure there was no dirt in any of the connectors incase that was causing something. No joy.
So to summerize:
1. Factory Reset
2. Replaced Battery
3. Changed power leads
4. Cleaned device
5. Flashed to completely new firmware
I've completely run out of ideas on what it could be. Why would the phone operate absolutely fine under 85% power? Its just weird! I'd appreciate any help some one could provide me. I've not seen any one else with this problem on the internet. Please let me know what you guys think.
Thanks
Craig.

Sorry to hear about this man!
I am completely stumped on this one! You've basically done all the basic solutions but to no avail. I had a problem similar to this where my device would reboot randomly, whenever it wanted to and in my case, the solution was to buy a new battery and that actually worked. I've had the battery for almost 2/3 months now and it's still going strong.
Back to your problem, I honestly don't know of a solution. I really wish I could be of help but as I said, you've already tried the basic solutions.
Again, sorry to not be of much help!

I think I have the same problem as you did. After suddenly dropping and rebooting, my battery level jumps back up when the phone starts, and again, and again. The phone is functioning normally only when plugged in. I also presume that it is a battery problem, but the fact that the battery level rises back after dropping, makes me wonder.
EDIT: Problem solved with buying a new battery.
Sorry to jump in, just curious, did you solved this? If you do, hope to hear your solution, might help others in future
SGs3n SlimKat9.0(Android-Andi)

[Q] Bootloop, software or hardware caused?

Hello, Its been a long time since I don't ask anything on the forum, but in this occasion I haven't found any solution to what's happening to my Xperia Z, I'm gonna do my best to present the issue.
A couple of days ago I updated my Xperia (unlocked bootloader) from Existenz 1.5.5 to the latest 3.0 and the phone was completely fine for 2 days until it started shutting down by itself constantly and with no apparent reason, so I started to get worried, the first thing I did was try and reinstall the ROM thinking that I had some something incorrectly, I has no luck with that, on the contrary the phone died on the middle of the installation and it got bricked. My next step was to try do do everything from scratch, flashing the stock rom 10.5.1.A.0.283 to root it, install recovery and try flashing the Existenz after. I managed to do everything with lots of unwanted shuts downs in the middle but I managed. Unfortunately the phone kept on having the same problem so my last option was to try and use the Sony bridge on my mac to try and make a factory reset but it didn't let me because it detected the unlocked bootloader so I relocked it with flashtool, after that I tried again and it worked, it installed the official stock rom .101 and guess what..... same issue again, when I try to turn the phone on it shows the sony logo and turns off, if I try to turn it on connected to the AC it turns on but if I start playing with the menus and options it disconnects again, ofcourse if I turn it on connected and once it's on I disconnect it it shuts down almost instantly, At first I though the problem could be software, then hardware so I tried to check the battery status in the service app and it said good battery health so now I'm completely lost.., I've found this: http://forum.xda-developers.com/xperia-z/help/hardware-fix-xperia-z-charging-booting-t2760911 but I don't know if thats my case. I was gonna go to a sony store and ask them what could be the problem, but now I'm living in Brazil and it'd take lots of time and money to get ir fixed here.
I really need help here, sorry if I posted on an incorrect place.
I just found a video of someone with the exact same problem, in case in helps: https://www.youtube.com/watch?v=zkvLchJ_0oU
UPDATE: I rooted it, install recovery and once im in recovery it doesn't turn off by itself what tells me that may not be a hardware problem, at least not battery related, all this just makes me feel more confused!!
UPDATE 2: I rebooted the phone to load the recovery again and the battery indication went from 89% 2 minutes ago to 11% this second time, maybe it's hardware after all..
Battery.....
TapaTalked from my Xperia™ Z (C660²) running Ultimate PureXZ Ultra!
I seriously don't think is the battery, I think it's something related to the energy but I'm not sure what. As I said before the battery went from 89% to 11% quite fast but when it was at 1% it stayed there for hours, if it was the battery wouldn't it had turned off? after it finally turned off I left it charging for about 12 hr and today morning I try to turn it on without it being connected and no luck, it kept shutting down after the Sony logo. Sometimes when I turn it on with the cable connected it loads the OS and I unlock the lockscreen, diconnect the cable and extraneously it stays on just with the battery power, I manage to put the ScreenOff timeout to 30 mins and it stays on all the time, as long as I don't do certain things like opening the camera, phone or sometimes it just randomly turns off from anywhere. I know it's not the rom because I've tried 4 different ones including the official installed by Sony Bridge....
If the issue is software related what could it be?? the bootloader? the bios power management? battery stats? maybe restoring TA backup(because I just relocked the bootloader using the option o flashtool, not flashing the TA backup)?
I'm concerned about buying a battery, installing it and seeing no change as I've read happened to some guys with the same problem.
I really like my phone but after this I'm not so sure i'll buy another Xperia because this has happened to so many people and apparently there's no solution, my phone is out of warranty and I life in a foreign country (Brazil) so you guys are all I have...
Same Problem Here ... Impossible to flash either from fastboot or from CWM or TWRP
Hi, I am having exactly the same problem. I was trying to revert to stock kernel from CM10.2 and was following one of the many guides here on XDA. The phone was not passing the «SONY» Logo, and immediately after such logo it simply went completely black and the phone is off. After two days of trying several things, including Fastboot of Stock ROM, fastboot of different boot.img files including Doomlord, using Sony Bridge for Mac, all of which did not solve the issue, the problem now is that when I try to flash any ROM, the flashing operation begins and then after approx 15 seconds the phone goes black and switches off. The battery is at 82%, so I am quite sure it is not a battery problem.
I am more and more convinced that the internal filesystem (or simply RAM) needs to be formatted at low level from scratch.
The only problem is that I do not know how to do it: how to do LOW LEVEL Formatting of RAM? Any instructions out there?
Any other suggestion?
Thanks

It seems like there's no solution and I don't think my battery is broken so I won't try the Hardware Fix since I don't wanna break my phone more than it already is, tomorrow I'll try to go the a Sony service store and see what they think the problem is, since I unlocked my bootloader and relocked after I think they will be able to see this, I think it ain't gonna be a problem because my warranty was void long time ago, and it's 1 year anyhow.... I hope they recognize it's a sony's fault issue and they decide to fix it with no cost, very unlikely but hoping is free gcecchini, i'll keep you updated, also if you find a solution let me know.
Hi Ringox!!! I'm having exact problem as your's.. This all started when I upgraded to 4.4.4 . First it was giving some weird problem like when opening camera , the phone shuts down. Then a time came the device was not charging.. The device boots up when connected to wall charger. But as soon as charger is removed the phone shut's down. Without connecting the charger when I tried to power on, it shows sony logo for 1 second the shut's down. I tried installing every stock rom , custom rom, kernel etc and it didn't solve the problem. I also bought new battery but same problem. I don't think it's software or hardware or battery problem but may be bootloader is corrupted. May be when we flash bootloader ( as in samsung) we may solve this problem. But I cannot find any tutorial an instruction to flash bootloader.
Also from quickstyler thread I can confirm that I have same problem as him, the sony mobile battey test app shows same error battery temperature -30 C . But his hardware fix didn't work either.
By searching for the problem on youtube, xda, google and other sources I can confirm 1000s of people is getting this problem ..
Please developer and member , help us provide solutions and tips what we can do next...
I have news, after one month waiting for Sony to repair my phone they've finally said it can't be fixed and they said the problem is the motherboard which is approximately 130 dollars plus installation, so I decided to park my Xperia and buy a SGS4. Something interesting that happened is that now the phone starts and sounds, just with a black screen all the time with the backlight ON, maybe they fixed something and broke something else, I don't know. If anyone knows a solution to this rather than changing the motherboard I'd appreciate the answer. I wanna fix it to give it to my mother, but I won't be buying any other Sony smartphone ever again, their service is a disgrace and I couldn't be more unsatisfied with them.

Xiaomi A2 dead as a brick

hello all,
I have a Xiaomi MI A2, just a year old, and now dead as a brick. What happened over the past few days:
• After restarting the phone it got stuck in the white start up Android screen with Android's logo;
• Then I tried to load Fast Boot, in which it got stuck as well;
• Eventually it started up again, I tried to restart it and back to the issues of the first two bullet points;
• And after trying a few more times: dead as a brick. It doesn't start in any way, however long I press whatever combination of buttons;
• I don't see the battery symbol on-screen when I charge the battery, nor do I see the battery charging light on. I was advised to replace the battery, so I ordered a new one, and... nothing.
Googling around it seems to be a common issue, but no definite solution found.
Anyone any ideas?
thanks in advance!

Issues probably occurred with first november update . Well for me also this issue i removed sim and plug in charger and as u did, did power on/off finally when i saw battery screen it started. I managed 4 restarts then never turned off. Just today did the ota to 10.0.0.17 (problem rom is 10.0.0.15!) And no probs any more. If that does not work u need to flash to earlier rom or latest.flashing through fastboot could only be done but bringing the phone to edl mode. E.g opening up phone.. i never got that far since i managed to keep it alive but google it.
Good luck

Issues probably occurred with first november update . Well for me also this issue i removed sim and plug in charger and as u did, did power on/off finally when i saw battery screen it started. I managed 4 restarts then never turned off. Just today did the ota to 10.0.0.17 (problem rom is 10.0.0.15!) And no probs any more. If that does not work u need to flash to earlier rom or latest.flashing through fastboot could only be done but bringing the phone to edl mode. E.g opening up phone.. i never got that far since i managed to keep it alive but google it.
Good luck

Perfect glad i could help. You should check your rom version (see about screen) if u on 10.0.0.15 you should check ota. I installed the ota while charging. And now everything works as it should!
Well, I went through all the options, without result. Eventually brought it to a service center. Conclusion: CPU broken. How the *** has this been possible!?
thanks anyway.

hello all,
I have a Xiaomi MI A2, just a year old, and now dead as a brick. What happened over the past few days:
• After restarting the phone it got stuck in the white start up Android screen with Android's logo;
• Then I tried to load Fast Boot, in which it got stuck as well;
• Eventually it started up again, I tried to restart it and back to the issues of the first two bullet points;
• And after trying a few more times: dead as a brick. It doesn't start in any way, however long I press whatever combination of buttons;
• I don't see the battery symbol on-screen when I charge the battery, nor do I see the battery charging light on. I was advised to replace the battery, so I ordered a new one, and... nothing.
Googling around it seems to be a common issue, but no definite solution found.
Anyone any ideas?
thanks in advance!

Question Mi 11 keeps on getting Dead Boot

So I recently updated to MIUI 14 and after using my 55w charger and playing some games, my device won't open anymore and it's just black screen, won't even charge (or what they called Dead Boot)
Then I have it fixed with a local tech, got to use it for 3-5 days tops, then it happened again. Tech says it was due to overheat. Now I am just so afraid to use MIUI 14 and wanted to know what's the best kernel and custom rom you can suggest? Also what are your suggestion to stop my phone from being "deadboot"? Thanks!
Mi 11 users have been experiencing the frustrating issue of their device getting stuck in a dead boot loop. This problem can occur due to various reasons, including an incompatible firmware update or faulty hardware. However, there are a few steps that you can take to try and fix this issue.
Firstly, try restarting your Mi 11 in safe mode by holding down the power button until the screen turns off and then pressing and holding the volume up key until your device starts in safe mode. If this doesn't work, you may need to reset your phone's settings completely or even perform a factory reset.
It's important to note that attempting these solutions may lead to data loss, so it's recommended that you back up all important files before proceeding with any troubleshooting steps.
If none of these methods work for fixing your Mi 11 dead boot issue, it's best to seek assistance from a professional repair service or contact Xiaomi customer support for further guidance.
Despite being frustrating at times, technical issues like this remind us of how much we rely on our smartphones every day. It also highlights the importance of taking care of our devices and keeping them updated regularly.

Thank you! Yeah it kinda sucks how faulty MIUI can be. I'm just so scared to use my phone now unless I found the best custom rom to use it daily again, and tweak it to stop from overheating (couldn't even use my 55w charger now).
I tried different methods before sending it to our local tech. Even draining it for a couple of days didn't work. I've been to more than 10 different tech but only 3 had tried to fixed it. Other says the cpu already needs replacements and such - but everything now looks great and I am happy some of my local techs are great on fixing this issue.
Just hopefully I can found other recommendations to stop this traumatic event from happening again.

Hey, there ain't really a "best" custom ROM tho, but they're all better than MIUI no matter what one you choose.
Just try out a bunch of them and see what's the best fit for you!
Hoping your phone doesn't break again
Ive had a problem after miui update too. Not as bad as yours but my speakers have stopped working rendering it unusable as I take a lot of calls. Only fix is using Bluetooth but I want it resolved so back to my Poco x3 pro. I'm currently in the process of unlocking the bootloader, just need to wait 6 more days.
A shame that warranty only ran out just over a week ago
I have installed custom ROMs before but our of desperation I asked if I could flash a stock rom with fastboot on a locked rom, but no reply and upon further research it just seems too risky. Rather wait the 7 days to unlock it.
