[Q] Big Big Big Trouble - G2 Q&A, Help & Troubleshooting

Hello guys I need your urgent help.
I dropped my G2 and its camera's ois was broken down. I ordered an original one from the internet and changed it on my own. To this point everything seemed normal. After changing it, when I plug it in it says slow charging and takes half a day to fully charge. Moreover, my computer doesn't recognize my G2 anymore.
I tried to uninstall the camera hardware I just installed and tried to recharge the phone but nothing changed. I also tried to hard reset it and it didn't work either.
Please someone tell me what to do from this point on. I have even no idea whether it is from its software or hardware. If it is from its software, I dont know how to fix it without connecting it to the pc.
The slightest idea would be appreciated. Thanks in advance.

[Q] [Help]HS2 Wont start after new LCD

Hello all.
I have a HD2 that I havent done anything with, exept getting and installing some small programs.
No new ROM, no attempt to install W7, its more or like a Virgin.
However I made a fool of me, and managed to damage the LCD and finally got it changed. Got the Phone back from the company (MBlue Ltd in UK), and tried to start it up. But No....
Pressing ON, the phone vibrates, gives some light in the screen, sort of like you see its ON its a "white glow", but you dont get any more. The Jingle comes on, theres light in my buttons at the low end of phone, and NOTHING more.
I have had it on for long time, but nothing....
When I finally sendt the phone away, the battery was discharged, but as I have a new battery I put that in, and it charges and all.
Ive studied this thread: forum.xda-developers.com/showthread.php?t=638210
But as I CAN charge I fell that Im somewhat related but not fully in the same situation as the Original Poster there.
# Could it be that my phone somewhat has gotten overheated or anything else?
# Is the only and best solution to send it to HTC and let them look on it?
Ive tried to HARD and SOFT reset, but still nothing.
[EDIT] Connecting the phone to my PC, It is recognised and its recognised as a HD2 T8585
Looking more and reading more on the Forum I suspect theres a problem in the connection between the "fx-card" and the screen. (stupid way of saying it though)
Glad for any input here. Thanks in advance.

Does your computer synchronize with your phone(connecting to activesync/mobile device center)? Then it is booted in Windows Mobile, the possibility is that the screen is broken then.
I thought the Screen might not be properly connected, or broken yes.
I better get in contact with the repair company.
But if other too have opininons, please bring em on... ;-)
Returned to repairplace, they fixed it.
My best guess is thy didnt check their own repair so they had to connect/fix something.

Good point, they're responsible for their repair: it is better this way because it's possible they damaged something while repairing and that part, if needs replacement, it should be their obligation, not yours!

This may just be it for me :(

Well after just recently getting another shift(not new), it too has died on me . While running jellybelly i got a lockup and went to pull the battery. That was the last time my phone was on lol. Happened yesterday afternoon, tried connectiong to usb, every one of the 3 batteries i have wont work, wall charger to get it on. Nothing. Not sure how or why cause it was running fine. Now it just wont turn on. Not sure what to do since i cant adb or fastboot. Wont go into recovery or anything either before anyone asks. I think its just dead. I'll keep playing with it trying but if it doesnt work, this is it for me guys. Sad considering the recent progress on this device. I'll probably stay on the forums though. If anyone else has had this problem lmk.
Very sorry to hear that. This really is an awesome device once you take off its leash
Anyway good luck with whatever replacement you happen to get! Don't be a stranger

[Q] Tricky and sticky situation!

So I have an LG G2 on my hands, I've dropped it twice now and the second time the screen shattered. And now it won't register any touch at all. My dad is going to India soon and he's going to look for someone to fix it there (because its cheaper in India I think). But the problem is, I want to back up my data before he does it and I don't know how to any more. I've tried plugging it into the PC but it won't register the device any more, tried installing usb drivers via device manager but no luck. Can'd do anything on the phone either because no touch. I'd be happy to be able to do a remote wipe, don't even care about the data any more. Just don't want anyone else to have the data (no there're no nudes on it, but other sensitive / personal data).
Any suggestions?

The phone can still boot, right?? If you have one of them USB on the go cables/adapter, then you could just plug in a mouse to operate the phone
Oh god why didn't I think of that! Brilliant! You, sir, are amazing. Many thanks!

[Q] HELP! Note 4 unable to boot up

Hi guys!
So while using my phone halfway, it suddenly powered off and died. At first I thought it was something small and tried to power it on again, but unfortunately it seems to be a much bigger problem. I am unable to do anything with the phone at all. It's become a literal brick.
I have not done any rooting nor have I dropped the phone into the water. I dropped my phone a couple of times, but it was with a proper phone cover.
When I tried to charge my phone, the charging light did not come on. I have tried the battery in an external charging kit and it works fine, therefore I do not believe that it is a battery problem.
The lucky thing is that my phone is still under warranty. However, I was told that the SOP for servicing the phone is to remove all personal data during the recovery process.
Unfortunately, I didn't back up the files in my phone because I didn't see any signs that the phone was gonna die on me, so I was wondering if there was any other way to save my data.
I read online that it may be worth trying to use a USB jig to try to force the phone into download mode. Is this possible? Does anyone know where I may be able to purchase one?
Unfortunately, I do not know which specific model my carrier sells, but it's a Qualcomm 2.7 KHz 4G+ note 4. Can't remember the exact firmware it was running on, but it should be the latest stock firmware.
Would greatly appreciate any advice. Thanks!
Is there anyone here who has any advice for me?

jig is basically a 300K ohm resistor across pins 4 and 5, so searching for brand names/judging by marketing descriptions won't help. It can only fix soft bricks for you, specifically it lets you enter download mode where you can use odin to flash stuff you want. It wont help you in any other way.
Now that we are clear, the cheapest ones I could find are these:
http://www.amazon.com/SainSonic-Dongle-Samsung-Captivate-Vibrant/dp/B0053H73JQ
http://www.amazon.com/Download-adapter-Samsung-Galaxy-Unbrick/dp/B008THL0V4
Buy whichever you like
And if its a hard brick, off to the service center you go!
PS: i have no idea about any way to backup from download mode, maybe someone else can help you on that part.
If you are able to dirty flash a rom and get it booting then you can backup all you want. Hope that works for you.
Thanks for the advice!
Unfortunately because I wasn't able to power up the device I had to send it into the service center. They replaced the motherboard and the charging point for me and I got back my phone 4 hours later.
Lesson learnt, always backup your data every day.

Screen dead + Front camera keeps trying to open

Hey!
While I was calibrating my fingerprint, phone suddenly turned off and went to recovery with screen off.
I managed to reflash stock rom through fastboot and it boots to system fine, but the screen stays off and the front camera keeps trying to open while playing the MIUI camera sound (sometimes, while booting, the camera does manage to open once, kinda like it's calibrating). Some playing around with ADB and it seems that the SIM isn't recognized either.. antenna maybe?
I opened the phone up and checked everything, there's no visible issues with the electronics, however it could just be the inside of a cable that died?
Does anyone know what this could be? I noticed the screen, fingerprint reader and antenna are all connected to the same removable PCB, but the camera isn't so that's odd.
Aren't we moving way too fast here? Like wtf is happening rn?
First: Explain in detail from the beginning please if you want help.
Second: Please state exactly what is your issue, and the ROM version of your device.
I don't think what you just did is the cause of whatever problem you're facing, do you mind telling me the source from which you got this phone? Otherwise you might want to send it to a service center.

It's a bit of a long one, so I didn't want to bother too much with the details if anyone knew what those specific issues could be caused by, here goes though:
I am on a Mi 9T bought on Amazon Italy in July 2019. I cannot comfortably send it to a repair center due to every authorized shop around here is just a drop-off point for Xiaomi RMA. I talked to them and, due to (>6 months old) glass damage to the screen and back of the phone, they intended to charge me way more than I can afford, as "solving issues covered by the warranty would require us to replace the accidentally damaged components"
As for what happened:
I was running LOS 17.1 with no issues for a few months. I went to unlock the phone and I heard the reboot vibration, which sent me to recovery (softbricked) but with no screen signal. I assumed it was just a software problem, so I flashed MIUI 12 (global, V12.0.7.0.QFJMIXM) to see what would happen.
As it completed, the phone rebooted itself, the MIUI logo popped up and it went to system (seemingly) without any issues.
I went through the initial wizard and played around with it. everything seemed fine and I even made sure the screen did work in recovery and fastboot. Later, when I went to setup the fingerprint reader, the screen went blank for half a second when I first touched it, and then the same screen death -> reboot to recovery.
The phone was softbricked again, though, this time, reinstalling MIUI didn't yield the same success. Now:
MIUI boots "normally" again
The screen isn't working at all
The front camera opens, as if it's calibrating, when system boots up
The front camera randomly tries to open again every now and then, failing to do so as if the motor is stuck, while MIUI plays the camera closing sound.
Meddling through ADB, the antenna doesn't seem to be working, but I can't be 100% sure due to the methods used
The power and volume buttons, speakers, and the charging light all work.
I have opened the phone up myself, thoroughly checked every cable, connection and PCB, but there is no sign of damage. I put it back together and the same issue continued.
My best guess is that something inside the fingerprint reader went bad and shorted something else.
What that something else is, I couldn't find out. Given the antenna, screen and FOD are all connected to the same little PCB which then runs a couple cables to the motherboard, I am now in the process of finding a couple replacement cables to see if that fixes anything.
As I mentioned before, repair centers are not an option due to the lack of anyone who's willing to help me for less than a good chunk of the price of the phone.
Interesting. So basically what happened is due to the initial soft brick and accordingly you flashed a global MIUI 12 ROM, which in return brought you to the second soft brick which caused some issues within the hardware of the device.
Now you're stuck with a faulty screen, a faulty camera and a faulty antenna.
I don't have the skills to play around with the motherboard and the phone circuit. And I don't care which youtube tutorial you saw, you should have NEVER done that - Of course unless you're actually experienced in that manner, then I apologize for speaking with such prejudice -
I can't help you if you messed up your phone circuit since I have no knowledge about android hardware, however I can safely assume that what caused your issue isn't related to hardware.
I think the issue is caused by an incomplete flashing of a ROM (In this case MIUI 12 global) OR flashing a different variation from your device.
e.g. you flashed only the ROM, but didn't flash the other components of the ROM.
Needless to say, flashing a variation of the ROM that isn't meant for you device can be a disaster recipe.
I recommend flashing LOS again, since you can't go back on Xiaomi devices due to rollback protection.

I understand why you'd think that and have seen people do similar stupid things, however I didn't watch any youtube video and know what I'm doing quite well.
I made sure I flashed the correct rom through fastboot to restore everything to stock. I did try to reflash LOS and whatever else (though it's kind of a pain with adb shell), but it doesn't fix the problem, sadly.
That's why I'm betting on a HW issue.
The fingerprint reader and everything else worked flawlessly in LOS for months, but it made the screen go blank and bricked the device in both LOS and fully functional, stock MIUI.
Currently, I'm battling with this damn thing to get USB debugging working while booted to system, so I can do a few things like cast the screen to my PC and see what works from there.
I have access to fastboot and recovery, but everything I know (editing build.prop or patching the boot image) didn't work so far. Do you have any idea what I could do to get that done?

If the touch screen is dead then you can use mouse and OTG cable.
If it is completely black then you can get usb c to HDMI cable (Also usb c hub might work, like this one). Or you can use playstore on pc to download and install apps like (Screen stream over HTTP) on your device, just make sure your device is connected to the internet and you're signed in on your phone as well, you might have to type in the screen password if you have one.

I don't know why bother with build.prop unless you have the wrong fingerprint prop. Then you can get the correct one from your device's stock ROM, though I think this is irrelevant to your issue.
All I can think of is:
Wiping dalvik cache, though you might have already done that.
Trying other custom ROMs from here.
You may try to get your device rollback index and installing a MIUI ROM that has index higher than it, and see if that works.
That is as far as I can help, unfortunately.
I have zero knowledge when it comes to hardware, so I can only help with software issues. If none of my solutions worked then sorry for wasting your time :/

Wait, does it actually just automatically use it as a 2nd screen if I connect it via HDMI?

Sorry, I didn't explain myself, I'm looking for a way to enable USB Debugging without a screen. Thinking that using adb in twrp is the best way, but I can't manage to do it. Do you have any ideas?
If I can get it on, I can then use things like scrcpy to get screen signal through USB.
Main problem with everything else is that the screen is 100% dead. Even with usb otg I don't know how I could possibly get through the setup wizard haha

I haven't tried it myself, however it should detect it as a second monitor. Give it a try the cable isn't costly at all anyway.

TWRP has debugging mode on by default, however that strictly applies to recovery and fastboot modes only as debugging mode is pretty powerful and can cause security issues. So you better forget about it.
I saw one of my friends who owns an authorized service center use some cable connections to get the screen to display on another touch screen. If you have the capabilities and resources I recommed trying it, though don't mess too much with the motherboard.
Just a question though, can you confirm if the touch is working? If not then there's a chance - Although slight - that this is just a UI problem (Which is pretty common in MIUI ROMs for some reason). In that case deleting dalvik cache or completely reflashing the ROM might solve the issue.
I may not do much help but certainly someone there can help so it's better if you include "usb debugging" in the title and/or the tags. Like changing the title to "Enabling usb debugging without screen" or "Screen is dead, need help to flash ROM"
Using proper title and proper tags can get the right person to help.
