Question Plan to buy Redmi 9t as Secondary Phone - Redmi 9 Power / 9T

Hey guys.
I am planning to buy this phone as a secondary phone. Do you guys recommend?? Heard about bricking/dead, what you guys think??

The deadboot issue is real, but apparently it is only in phones manufactured within a certain time period. I believe that any newer models (models after 2021) are fine. Other than that, the phone is good, and I'd say it's a little overkill for a spare phone, but it's a great all-rounder.

Thanks for the reply. The dead boot issue is a hardware issue or a software based?

Not sure of this, users say it happens after a certain miui update, and may have now been fixed in 12.5.5 enchanced.
Repair shops say that it's a hardware issue with the power Ic shiled/cover not having insulation and shorting a capacitor.

not a solution, as I did it already twice, after a week or two you need to do the same. Probably the only option is to change the motherboard.

Hello i had same problem with phone. Totally dead, then i read on forum that it is probably pmi8994 chip on motherboard that was defected. I order that chip from aliexpress( must know what version is chip on your phone). Mine was pmi8994 002. I paid 8$ on aliexpress for two of them(you need only one) and 35$ for replacement. After replacement it come alive and working fine more than half year. I hope this will help.

It was suddenly power off and didn't want to turn on. I put it on charger (before failure battery was around 70%), but it didn't power on and notification light for charging was very dim and blinking. Then i check my domestic forum and got solution from one user who had same problem.

How did you change the chip? I saw a video on Youtube that describes the procedure of changing a chip, and looks like it is definitely nothing for laymen.

Should I buy it? Savable or trash?

Good evening friends!
I'm on the hunt for a new smartphone and found something interesting in eBay.
Please give me your opinion on if I should bid on this device, or not!
It's the 128GB 6GB RAM variant in quite good condition.
The seller states that
Android 10 installation couldn't be completed.
The installation process stops after a short time
Device reboots by itself

I've read that on one hand that it's hardware/soldering issue,
and on the other hand that it might be just a software/firmware issue.
I've lots of experience in flashing all kinds of phones, including the Xiaomi Note 7 Pro (probably) of a friend.
So given I can unlock the bootloader and something can be done in software, I'm pretty sure I could do it.
Also I probably could open the device up and try to fix the mainboard.
Has anyone ever tried reflowing the mainboard?
Otherwise maybe I could replace the mainboard, if financially viable.
So please tell me if I should bid on it, and how much you reckon it might be worth!
Thank you very much and have a nice weekend!
My advice is to get a working phone. Instead of one where u have to repair. A working mi 8 is not expensive nowadays

Actually I faced the same issue with my K20 pro. Nothing worked for me , power button didn't respond and I took it to service center, surprisingly there it turned on without giving to them, Even though It's working fine now, I gave them to check for the black screen issue, and they replied they didn't find any log for that and even they answered the last used app on my device. From that I concluded it's a software issue.
Again till now, I didn't face that issue. If I'm wrong please correct me.

There might be many possibilities, but did they repaired it somehow, or just checked and gave back to you.
If it's given back to you without doing any repair of any kind. Please be very cautious, this devices will go black eventually. Please make a action as soon as possible before same happened again.
You can search and read other users review as well. This phone manufacturing must have a serious manufacturing defect that all users will experience some day

That's great, Could you please let me know how that software issue got solved.
Currently my phone's screen is black. I can't use it.
I do know its working fine by the sound of charging plug in and out and calls coming.
I m frustrated and going for a IPS LCD display worth 3500 rs since amoled will cost around 9000
This is my last try to solve it if I can.
So please share your experience how it was solved

Frankly I did nothing.
It worked fine itself. I got scared to switch to custom roms coz I thought it as a hardware issue, later came to know as a software issue. I heard that some people had fod issues with miui 12 after screen replacement. I can't guide you in this case and please do proper research before spending money.
Thanks

You are talking about fingerprint will not work on IPS LCD display, yes that I do know.

I can use other ways to unlock so it's kind of fine with me

Question Zenfone 8 suddenly died - no sign of life - Asus EU support not covering because of an unlocked bootloader

Hi,
A week ago I was using my < 4 months old Zenfone 8 while traveling in Germany, and at 19% battery the screen turned black. I went back home, tried charging it for as long as possible, it was staying cold and never showed any sign of life.
So I opened a RMA on Asus Belgium website (as I am from Belgium), and shipped the phone to their repair center.
Today, I got an email from them, saying that the warranty wasn't covering the damage, and that I had to pay 500,28€ for a replacement of the motherboard.
When going into their OOW website, I saw this table :
Warranty start:2021-05-16Warranty end:2023-05-15Issue date:2021-09-13Receive date:2021-09-15Charge reason:OOWCustomer agree to quotation:Charge reason:OOW - Out of warranty ASUS Product Unlock Flag-oow scratched
It seems to me that the "unlock flag" is their bootloader unlock tool, that I had indeed used to root the phone before, and wanted to try a few custom ROM - which I actually never did since there were none at the time. Of course, this is completely unrelated to the issue, as it is not even rooted anymore and I basically did nothing with it.
As I am from the EU, I saw that there are laws that protect consumers from these types of abusive behaviors from companies, as explained here https://piana.eu/root/
I am therefore
1) looking for people who had this problem with their Zenfone 8 (what is it actually? never seen a brand new phone die like this)
2) looking for people who had their warranty denied for an unlocked bootloader in the EU, and what is possible to do
Thank you very much for your attention and for your help
There loads of people that has the same bricked state:
ZenFone8 stuck on waiting for flashing full ramdump
As requested by the mod - opening new discussion for the issue. The Flashing Full Ramdump happened to me too - the phone was being charged over the night and the error was waiting when I woke up. I hope that at least your service will fix it quickly.
zentalk.asus.com
I had it on my 1st ZF8, complety dead. Sent it for repair but ASUS refunded it.
2nd one seems resistent to this bug, rooted, flashed all kinds of roms etc, ended in ramdump state but can always boot to fastboot.

I've seen that but I'm not sure it's the exact same state, as for me it didn't even display anything anymore. Also, did Asus refund you even with your bootloader unlocked?

You can also check state when you plug it to computer, even with dark screen.

Yeah I tried it back when I had the phone (since it’s now hostage at Asus) and nothing showed up in the device manager
So update: After a bit of back and forth emailing, I finally got an answer: « Im really sorry but our answer will not change. By using the unlock tool you have agreed that the warranty will be dropped, no matter what problem you are experiencing and regardless of how the problem arose. »
So basically they openly agree that they are scamming me of 500€ after selling me a faulty device, but thanks to an abusive clause, they think they can do it.
Great customer service, always a pleasure to give business to such a great company as Asus… I’ll get my lawyer involved now, anyone who has advices on the legal process in the EU is very welcome.
Seem to be some hardware fault with the 1st batch. Really bad customer response from asus, loads of reports of dying zf8's now

There are reports on Zentalk forums of both 128 and 256 models dying
We are basically all held in suspense wondering if our phones will die or not. Personally, I have a second phone (Xperia z5 premium) that is fully set up and I can easily switch in case of problems, but it is still not a nice feeling
Possible battery failure. Inspect.
I dont think its battery fail, seems more likely that storage or RAM gets corrupt, the 1st state is
"waiting for flashing full ramdump". I have this state on my 2nd zf8 but can always reboot to fastboot. That was not the case on the first unit

Was the 128GB model for me, we still don’t know what the issue is.
If I can’t get the phone fixed the legal way I think I’ll pay the 60€ to get it back unrepaired (because yes, I have to pay for that) and open it myself to try and find the issue. Maybe I’ll be more competent than their lame service at identifying the issue

Question Screen of Death , realy?

Ok i am a bit confused. I have today went back to the store to return my Oneplus 9 PRO that i was not happy with due to the heating and batterit drain problems that me and many other have. Instead I ordered a Samsung galaxy S 21+ with the exynos version.
But I have read that it is exist a problem called the screen of death for this phones?? Is this for real a common problem at this day?? I mean should i be worried??? My friend have the same model and have never had any problem with it and he have owned it for a long time.
Your post is the first I've heard about such a thing....
So I'd be inclined to think no
It's been happening for a while. Put it this way, you never heard about it happening on the N10+ except maybe an isolated freak case. This has happen to a number of S21U owners.
Not sure if it's across all variants or is variant specific.
It requires a display replacement if it happens.
I had it on my snapdragon S21U and had the screen replaced by Samsung.

If it works...
Generally when you need to do hard reboots you have a hardware not firmware issue especially if it happens more then once even if the hard reboot temporarily "fixes" the problem.

Hi,
So this screen of death is a common problem still? And if you have it is the hardware that is somehow broken? And it doesn’t matter if it’s snapdragon or the other cpu?

Don't know... do some searches with XDA or Samsung forum in the search parameter.
It's not just one or two.
From what people who had them repaired said, it was hardware in their cases.
It happened to me. Screen suddenly won't turn on. I brought it to samsung center and they replaced my screen.

There are a bad display batch(es) out there... at least that will fix your problem!
Worst case is if it fails out of warranty.

When did it happend?
Whatapk said:
Why Samsung Screen Turns Black and Dead? The most common reason could be your device's crashed system. When your Samsung memory gets lower, or you meet a system update failure, the system would be crashed and stuck with a black screen on your Samsung Galaxy. You can also play games like Yareel 3D Mod APK on such mobile with ease. just enjoy the phone

They were already shipped.
This is more then an isolated failure...
The Red Screen of Death (RSoD) refers to the error message that appeared on some of the beta versions of Windows Vista as well as a few handhelds and video game consoles, such as the Playstation series.
