[Samsung Galaxy A40 Questions & Answers] blackhawk:
Use anhydrous (preferably 96% minimum 93%) isopropyl alcohol.

I wouldn't go too nuts trying to save it due the price point and especially the fact it has known water damage. Buying a used one in good condition be a viable option if you really like that model.
[Samsung Galaxy A40 Questions & Answers] DannySolo:
I've just notices that with this model there is a pretty hefty flex between the top and bottoms boards with a connector on each end. This must also carry screen data so I'll give that a good clean out.

Second hand AMOLEDs are impossible to find for the A40, they all have horrible burn in.

I'm going to get the INCELL LCD version already in a new front frame and go from there. Should still be a decent back up phone.

And the fun of fixing it is what it's all about anyway, right? :-D
[Samsung Galaxy A40 Questions & Answers] blackhawk:
You grossly underestimate the corrosion process that's likely been initiated. I'm not so optimistic about it ever being reliable again.
[Samsung Galaxy A40 Questions & Answers] DannySolo:
I can understand corrosion while the phone is wet... not after it's been soaked in alcohol and completely dried. The process doesn't continue.

I'm going to guess it's the screen only that's broken as I see no other issues... I bought a cheap LCD replacement already in a new frame for $30.

Let's see how it goes.
[Samsung Galaxy A40 Questions & Answers] blackhawk:
Yes, yes it does. Most don't understand how insidious it is. The oxides formed are insoluble in water and alcohols. Many are hygroscopic and attract moisture, then you know what happens...

This is the same reason you never buy a flood damaged car. Even if everything is working it will start to fail sure as the sun rises in the morning.

Sometimes if you pull the battery before the flooding it can be saved... sometimes. Always check for signs of water damage when buying a vehicle. EV's just burn to the ground when water damaged🤣

Energized circuits greatly exacerbate and accelerate the corrosion process. You see the results. The future is uncertain for that phone but it will likely eventually fail from that one prolonged exposure.
[Samsung Galaxy A40 Questions & Answers] Mikicrep:
tell results :)
[Samsung Galaxy A40 Questions & Answers] DannySolo:
OK so the new screen eventually arrived and I turned on the phone then plugged in the new screen... nothing. But I guess you have to plug in the screen and then turn it on, but that seems to be impossible with the A40 where you need to attach the middle frame for to use power/volume, and that blocks the screen connector.

Is there some way to bridge those little spring contacts on the PCB to reproduce a power on signal? Otherwise I'll just have to do the whole replacement process and see what happens at the end!

Just as well there's holidays coming.
[Samsung Galaxy A40 Questions & Answers] Mikicrep:
i do not know, sorry, never opened my a40, still using it right now
[Samsung Galaxy A40 Questions & Answers] DannySolo:
Necro time!

So a year later I finally swapped in a new screen and not a peep of an image. The phone is still alive inside and powers up with a vibration and the alarm will sound at the time it was set years ago but the screen is totally blank. I cleaned the ribbon contacts again but no luck.

Back to EBay for that replacement screen then!

Now for one last Hail Mary I'm going to try to find a dirt cheap USB daughter board as there's a guy on Youtube says that's a weak point. Might take another year though so talk again in 12 months!

(Just handling the A40 again makes me miss that size phone and it had a beautiful sleek shape)
[Samsung Galaxy A40 Questions & Answers] blackhawk:
Be easier to buy a working used one... just saying. If you really like it.
[Samsung Galaxy A40 Questions & Answers] DannySolo:
Haha, there's no doubt about that, but it's partly the challenge and partly that there are a few minor bits of data still there that I have nowhere else. For instance, I never set up the WhatsApp online backup so those conversations are lost.
[Samsung Galaxy A40 Questions & Answers] Gergo207:
Did you try rice?
[Samsung Galaxy A40 Questions & Answers] blackhawk:
Negative, rice is useless.

You got one shot to save it as I described in previous posts...
[OnePlus 7T Pro (Regular & McLaren) Q & A] mugel2110:
Hi. I am running my OnePlus 7t Pro with Lineage Recovery and LineagOS 19.1.

I had the battery exchanged with a new OnePlus battery. No after market crap. Before the exchange, the same LineageOS version die no show any of the problems.

Since then, my battery shows wired percentages. About 500-1000 mAh are used from 100% to 1% and for the rest of the battery runs on 1% for about 2000-2500 mAh. Sometimes the percentages jump down 10% in seconds. See attached images for reference.

What have I tried so far:

I have tried the usual calibration method 3 times so far, with no change to the problem.

1) draining the battery until phone switches off 2) Charging > 4 hours with phone off

3) Switching phone on, while still charging

4) Continue charging

This did not solve the problem.

Tried to dirty flash twrp to delete cache. Cannot do it. When I use

fastboot boot twrp.img the phone stops after a restart just showing an image fastboot mode".

Thanks for your help guys
[OnePlus 7T Pro (Regular & McLaren) Q & A] chrysopra:
Try fastboot flash boot twrp.img instead, if you want to install a new TWRP.

To delete the cache, why not start in recovery mode? Lineage 19 tends to install its own recovery, overwriting an existent TWRP. It looks different, but deleting the cache should also be possible in this recovery...
[OnePlus 7T Pro (Regular & McLaren) Q & A] mugel2110:
Sorry. Forget to mention. I used fastboot boot to use the twrp.zip installer. Using flash with twrp.img leads to the same result. Without lineage os being booted.

But does not look like the chance thing would solve my issues.

https://www.reddit.com/r/LineageOS/comments/pk8scm
[OnePlus 7T Pro (Regular & McLaren) Q & A] chrysopra:
First enter recovery mode (Shut down phone, then start it with simultaneously pressing power and volume down. After starting release both buttons and you will enter recovery mode)

There`s a very simple menu, not to compare with TWRP. Maybe under the "Advanced" button you could find a wipe cache...
[OnePlus 7T Pro (Regular & McLaren) Q & A] mugel2110:
Nope. No such feature in Lineage recovery. And other idea for the battery problem?
[OnePlus 7T Pro (Regular & McLaren) Q & A] chrysopra:
From within Lineage recovery you should be able to install a TWRP (either placing it in the download folder before or mounting an attached USB drive) Then, you could try to clear the cache.

As for the 7t weekly Lineage updates are provided, this may also be an option...
[OnePlus 7T Pro (Regular & McLaren) Q & A] mugel2110:
Sorry no. Was running with the exact same Software smoothly. My besteht guess right now is a faulty replacment battery from oneplus
[OnePlus 7T Pro (Regular & McLaren) Q & A] mugel2110:
Thats the current state
[OnePlus 7T Pro (Regular & McLaren) Q & A] chrysopra:
The battery of the 7 pro has got a capacity of about 4000 mAh. A fully drained battery should require about 90 Minutes on a standard USB2 port to become fully charged. USB3 delivers 4.5 Watts, therefore about 50 Minutes. (Loading with phone turned off) If your new battery is fully charged in shorter Time, this is strong evidence of a faulty battery.

As the percentage values of your phone seem to be unreliable, you could take the battery voltages, which should be accessible in AccuBattery as a measure for the energy status. If the voltage values correspond to the load percentages, then it`s almost proven, it`s no software problem...
[OnePlus 7T Pro (Regular & McLaren) Q & A] mugel2110:
Roughly 2000 mAh of the 2700 mAh used with 1% of battery. Above 1% I had about 4,050 mV. With 1% I had also about 4,000 mV. Than it starts to drop with ongoing usage. Now I have 3,700. Somewhere below 3500 the phone switches off.
[OnePlus 7T Pro (Regular & McLaren) Q & A] mugel2110:
Edit. Wired behaviour obsereved.

1) let the phone dying, charged it to 100% in switched off state, wait until it shows 100%, switched it on and the OS shows 100%

2) let the phone dying, charged it overnight in switched off state. In the morning it shows 100%, switched it on, OS reports 86%, switch it off, system shows 86% and charges. I could repeat the process. Charge it up to 100%, boot OS. OS reports a different value. Repeated it for 86, 93, 94, 95, 96, 97, 99, 97, 97, 100%.

By now, I really think that the chip of the bettery reports nonsense.
[OnePlus 7T Pro (Regular & McLaren) Q & A] chrysopra:
Your battery voltage is about 0,2V too low. Therefore it switches off at 3,5 V (instead of 3,7) and a fully loaded System shows 86% (@ 4V, I assume)

The software interpretes those Voltages as a (wrong) charge state.

You have got an additional resistor in your power supply (maybe a bad cable or not fully engaged connector). The spikes in charge state occur surely under heavy load, where the voltage drops, as the resistance prohibits your battery from delivery of full juice. If power consumption is back to normal, then the voltage raises again and the charge state is back to "normal".

You will have to reopen the phone (yes, it`s a pain in the ass) and check the resistance between battery and mainboard...
[OnePlus 7T Pro (Regular & McLaren) Q & A] mugel2110:
Full battery is 4,300 mV. 79% is still 4,300 mV and 65% is still in this area 4270 mV (See screenshot).

I use Geekbench to drain the battery for the calibration process. When I put heavy load on the CPU/GPU (e.g. Geekbench 5) the voltage drops by a guesstimate of 200-300 mV and recovers a few seconds after I stopped the load.

Seems to be exactly the behaviour you are describing.

I'll report the result after opening up the phone...urgh. don't wanna do it.
[OnePlus 7T Pro (Regular & McLaren) Q & A] chrysopra:
Were are the good old times, when you could swap a battery within a minute?

Even Glued together, most of the phones are still dying, when submerged in water. So I cant´t see any real progress, except for the revenues of service stations...

The battery of my 6t is still ok, but I´m afraid the day where a change is necessary. :eek:
[OnePlus 7T Pro (Regular & McLaren) Q & A] mugel2110:
It feels so wrong to hit the phone with high temperatures to loosen the clue.
[OnePlus 7T Pro (Regular & McLaren) Q & A] MAkram9008:
I have the same problem with a battery bought from repairoutlet uk, lineage os also.

But I thought it was a problem with the battery.

I hope you will keep us updated ..
[OnePlus 7T Pro (Regular & McLaren) Q & A] mugel2110:
I will. Just hard to get hands on a new OEM battery right now that not just has the OEM sticker, but is really original.
[OnePlus 7T Pro (Regular & McLaren) Q & A] mugel2110:
So guys. I have a new battery in. I'll keep you posted. After a first full charge, it seems that I have now the reversed problem 😂 already 100% for 60 minutes. Let's see after the first discharge/charge cycleView attachment 5773189
[OnePlus 7T Pro (Regular & McLaren) Q & A] chrysopra:
Glad to read your problem seems solved. The downside is, there are batteries sold as new and maybe "original", that are almost completly useless.

You may not expect the full lifetime and/or capacity when buying a third party battery, but I never encountered such a catastrophic specimen.

Especially with modern devices, where you can't just easily swap the battery within a minute, this is very painful.

What I've learned:

1. Buy only from credible sources, where you may get a refund, if you're not satisfied.

2. In any case, before attaching the backcover after a replacement, first check the battery status.

Hello

I have been trying to root my POCO C31 for mobile penetration testing purposes, I tried several ways to root it but no use. Can someone post a detailed guide to root the POCO C31?

PS: The device is running on Android 11 with MIUI version 12.5.3.RCRINRF, I looked up the fast boot file and a TWRP image but I could not find any! Kindly assist
[General Questions and Answers] Wmbruckner:
This is the forum for Poco F3, so I doubt anyone will be able to help you out here.
[General Questions and Answers] cyanGalaxy:
You can either flash Magisk.zip through TWRP/OrangeFox

or you can do a TWRP/OF Backup of Boot-partition, because the resulting "boot.emmc.win" is just an IMG-file.

You can patch "boot.emmc.win" with the Magisk App, and restore the patched Boot by renaming & replacing the original Boot-backup file.
[Xiaomi Mi 10T / 10T Pro Questions & Answers] fireseal214:
I have 2 year old MI 10T 5G, i encoutered a bug, where the headset icon is still on even though im not using it.After rebooting the phone only black screen is showing and cant do nothing the MIUI logo didnt appear after the MI logo powered by android. I did a wipe data and after doing so it asked for my MI Account password, i tried to type my password but it would'nt let me since the keyboard wont show and it keeps on doing a boot loop, im even stucked at fastboot
[Xiaomi Mi 10T / 10T Pro Questions & Answers] chrysopra:
Supposed you are on stock ROM, you could try to use the Xiaomi flash tool to flash the current system. With wiping cache but not data, your system should then be like before (the bootloop)
[Xiaomi Mi 10T / 10T Pro Questions & Answers] fireseal214:
Sorry im a newbie is it required to unlock the bootloader?
[Xiaomi Mi 10T / 10T Pro Questions & Answers] chrysopra:
If you´re on stock ROM and stay on stock, there is no unlocking necessary.

To gain root acess or to install a custom ROM or recovery, you have to unlock the bootloader.

[OnePlus Nord 2 5G] eastermo:
Hi all, I use a smartphone (e.g., OnePlus Nord 2 5G but what I describe next happens also with other smartphones) and plug a UICC (a.k.a. SIM card) into it. Then I try to start a SCP02 secure channel (SCP02 is a GlobalPlatform security protocol). First, everything runs correctly: the mutual authentication is done successfully and I can send encrypted commands to the UICC. Then I stop the secure channel. And I start again: new secure channel with SCP02 and a new encrypted command, and stop. I do this multiple times and up to some point (after 50 or 100 trials), when I initiate anew the SCP02 channel the UICC replies with an error "Invalid response SW after first INIT UPDATE command" during the authentication. If I use a times (that is, I wait 1 s between two tunnel establishment) I can establish more tunnels than previously (200 or 300 trials) but, eventually, the same error is sent by the UICC. Can anyone help me to solve this issue? Thanks a lot in advance.

Hi guys, just a quick one. I made my phone check for updates like an idiot not realising it would try and install it and now I'm on this screen below. I'm rooted so I don't want it to install and brick my phone. Is there anything I can do now to stop it and avoid a potential disaster?
[Google Pixel 7 Pro] Lughnasadh:
The OTA will likely just fail if you resume because you are rooted.

Well, I'm not sure what's happening, but normally it should work. The phone currently starts to the system correctly? Issue may be not related to what error shows. Try to reboot the phone, connect it to another port (USB 2.0 is highly recommended) or even try with different PC, update fastboot drivers if possible.
