Should I buy it? Savable or trash? - Xiaomi Mi 8 Questions & Answers

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

Also that
WIFI and mobile data are not available

And

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

Considering a Z1, some questions

Hey guys,
I am thinking to get a Z1, I am not living in the US (I live in Hong Kong) and here're my options:
- Asia Version (not Japan/Hong Kong/China)
Concern:
The quality (Some says the quality isn't as good)
The firmware upgrade (maybe they will come slower)
- USA version
Concern:
It needs unlocking
Both of which are same price, which is around $150 cheaper than every other version.
So my questions are:
Is unlocking the carrier lock difficult/unsafe?
I don't plan to use it for 4G. Is there anything else I should be aware of when I look to buy a Z1?
thanks for reading anyway, hope to get some answers to help me out

Unlocking is very easy and safe, and will be unlocked permanently.
thanks but I can't find a cheap unbranded Z1, they cost just as much as the Hong Kong version.
I guess US version is the safer option to go then?

It's worth knowing that until Sony fixes it, there is a problem with the camera breaking when the bootloader is unlocked.

He was saing about Carrer Lock. So I do not mentioned that. They have nothing in common. Unlock Bootloader is necessary only to flash custom roms with custom kernels.That's all.

Don't buy Z1 as there are many faulty units out there. It's a hit or miss on a good or sucky unit

I got mine fromm Singapore, is it Asia version? Dunno anyhow its provlem free except for the touch ossue that everyone have...
Screen is pretty, great blacks, device runs fast and and doesnt over heat. My serial is bh90l... Is that Asia version?
Sent from my C6903 using Tapatalk
so i have made my decision to just buy the japanese version.
The screen apparently is more red (he showed me a hk version and a japanese version) which I like a bit more.
It comes with a charging dock and a 32GB internal memory which I like a lot.
Problem:
Updating can get very troublesome, I think I will have to stuck with the not so good firmware (comes with the .534 firmware and not the .213, what's worse is that I don't think i will ever get the .213)
other than that, the phone is perfect, I am still playing around with the camera thoguh

Buying used one, what to check for?

Hello everyone, as the title explain, i'm just before buying a used Oneplus 3 (originally bought in Germany) and i'm really not sure, what to check for. (for example at MI5 there is the GPS problem, which if a knew before, i could have checked it before i bought)
Is there anything similar with this phone? Were there know hardware bugs with certain models?
Can i somehow check based on serial with Oneplus?
Any advice would be greatly appreciated!

I bought mine couple days ago (used) and everything is fine
Check the following:
1. If the other guy has bought it over the official OnePlus site (very important)
2. Check if the device has locked bootloader or not
3. Check for scratches on the Camera
4. Try pressing the screen a little bit hard to see if it has any flex or weird reaction (He may has changed the screen who knows???)
5. General testing (FP, Calling ETC)
No bugs with certain models (as far as I know)

Thank you very much for your fast reply!
1. Could you advice me further, how to check if it has been bought from the OnePlus site?
2. For the bootloader check does the keypad mode work (*#*#7378423#*#*), or shall i bring a laptop?
thanks again.

You're welcome
You can see check by checking on the receipt. It should have a order number and everything should look legit
No you don't. Just power off the phone and then power it up by pressing the Vol UP + Power button

Replacing Malaysia Samsung Galaxy Note 5 (N9208) with Note 5 N920t motherboard

Hello there, beginner here, my current phone note 5 motherboard was dead, (checked by phone shop). I'm learning to fix my phone by myself. But I found out there's little different between logic board model and its price.
I would like to have senior advice about the effect, will it affect the phone function to make calls if I insist to buy the cheap logic board to use back the phone?
Appreciate for any replies and helps!
Thank You!

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?

Yes, it was bootloader unlocked.
You can also check state when you plug it to computer, even with dark screen.
Check what the usb connection says in device manager

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

However people on Zentalk forums which have sent their phones for repair have reported that the service report has information that motherboard was replaced. I can't confirm or deny this

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 Device dead?

Hi,
my device does not power on neither is detect when plugged via USB or when plugged to charger.
I've already tried holding power button, power button + vol UP/down and nothing happens.
It had 60% of charge when it happened.
Now I'm just waiting to the battery completely dies to try to charge it again.
Or is there another command to reset it ?
Thanks
Try a hard reboot, hold power button for 10-15 seconds or disconnect the battery.

Hardware failure. Maybe the battery, the C port pcb, a loose connector or the mobo, in roughly that order.
Yeah, I'm started to think about hardware failure.
I disassembled it, everthing seems fine though. But the main board, memory and so I have no way to check it.
Thanks
So I'm giving up.... Leave it to spare parts, try to sell it as that....

May just be the battery. Any swelling is a failure but may fail without swelling. Older, degraded batteries are more likely to fail.
Try inspecting the ribbon cable jack pins. Simply detaching them then reattaching them is all it takes.

I thought that was the case, but I should have asked you that first. If you can't find the problem try taking it to a local repair shop. It may not be as bad as it seems. Could be a bad C port pcb which are cheap.

It will be close. Here in Brazil we have to pay taxes and import fees. So if I sent it it will cost (doing conversion) around 45usd shipping,+ 10 for insurance.
Then to get it back is about 60% of the product price to import it back + the service to get it fix.
So buying a new one it better, but I've already decided not buying OnePlus again the lack of tools to let us manage the phone was the real issue here... And also all the posts that users getting their phones bricked, even with beta android 13, how a company release something that a user can't go back in an easy way?
Sorry but OnePlus was nice, now it's just company and less users..

Just got the device in EDL mode. Now just need to find the full image for NE2213 in OPS format that is the one that MSM Tool needs. Anyone has any ideia ?
PS: Already tried to use the decrypt and encrypt tool to generate but I don't have the correct settings.xml file for this device.
And now I found out that V2.0.67 or V3 can read .ofp file...but those version require username/password.

Msm tool is locked down. It requires a technicians username and password. It also requires a phone home.
There's one loser whos going around selling stolen credentials for Msm. Hate to say it, but that might be your best bet?
Thanks, but not gonna pay a cent... If people starts to pay then we'll never get the tool for free.
So I prefer to lose the device or just keep it stored until the tool is available.
For the time being I'm back to my mi 10t.
And if the time for the phone support ends, just going to buy Samsung or htc if they get back on business
