[Q] Cannot Enter Recovery Mode

Hello All,
Hoping someone will be able to assist me, though I'm starting to lose hope.
I have spent all day so far reading threads, and trying various suggestions and fixes, but nothing has really helped and I'm beginning to think the phone may just be kaput.
Initial issue was nothing out of the ordinary; woke up to find the phone was not responding so pulled the battery. After putting the battery back in, the phone would no longer turn on. Uh oh. Did the obvious, repull the battery, try again. Nothing. Connect to charger (nothing happens, no charging icon on screen). At this point I think the battery has died so I bought a new one. No change, phone still won't turn on and nothing happens when I plug it in to charge.
So now I connect it to my PC, and I get the installing hardware message trying to install the APX stuff which fails. After some research, I manage to get the APX drivers installed such that the phone is detected when I plug it in. More research, decide to try the AOI Toolkit to backup everything first. This works ok.
So now I try and enter recovery mode via Power key + Volume Down key. Nothing. Ok, change the recovery image then. Device is not detected via ADB method. NVFlash method instead then. The bootloader loads fine, the screen wakes up and shows the S/W Download... message. I figure this is a hopeful sign. I try all 3 (ics-cwm-5, ics-cwm-6, twrp-2.5). They all flash successfully. However, I can't enter recovery mode with any of them. Once I disconnect the phone, insert the battery and then hold down the Power + Volume Down buttons, nothing ever happens.
I've also tried the LG Update Tool and the Smartflash options, but the phone is never detected.
As a last resort I repartitioned. This also worked ok, but still no recovery mode.
tl;dr
Phone won't turn on, show as charging, or enter recovery mode. Works when connected as APX with AOI Toolkit.
Am I missing something? Doing something wrong? Any assistance is greatly appreciated. Thx.

Bump

Okay, I'm bumping this thread myself (mostly because I'm an idiot and this could happen to me, too), but to give you my two cents: Have you tried the Full Brick Repair tool? You flash it through NVFlash and apparently "it cures any brick". Try it and tell us how it went.

Thanks for the suggestion. The flash process itself completed without issue, but still nothing once the battery is inserted and the power button is pressed. I'm going to assume there is some sort of hardware issue at this point and consider the phone officially dead. Now, where's my hammer...?

Don't give up yet. Try smartflash and flash stock, or whatever. Seriously. Just keep on trying. I had a Samsung Captivate a year back and something similar happened where I woke up one beautiful morning, tried to unlock my phone: no response. I thought I had an SOD, so I pulled the battery out, reinserted: bootloop. Entered recovery, can't flash anything, unable to mount system/data partitions. Turns out my internal memory/ROM got fried. Yay. But until then, I tried every possible option. Wow, this turned out to be a bit depressing. Just try more stuff. After you've tried everything, and I mean everything, declare the phone dead.

I think i have a similar problem. Just woke up to find my phone to be dead. Tried the usual methods, nothing. Best it could do was from time to time show me a battery sign with a red triangle and a whtie exclamation mark in it. Then sometimes i manage to get into the recovery mode, there i tried practically everything. Used restore, it shows that restore was a success, but when i reboot my phone i get into an endless circle of bootloader icon appearing and dissappearing,
EDIT: somehow from the countless attempt it fired up.

Make sure to have the right bootloader before nvflashing unbrick roms....

Try to flash a new recovery image in apx mode.
And edit the /dev/block/mmcblk0p3 partition your self.
seek=6144 count=75 bs=1 / boot-recovery

Thanks for the added input and encouragement folks.
Just reporting an update:
Having been unsuccessful more times than I could count, I decided to physically disassemble the phone (normally Engineering fix #2, but performed out of order on this occasion). I have zero idea why it should have made a difference, as all I did was take it apart and then put it back together, but the phone has groaned back to life.
Of course, then sausage-fingers here managed to tear the digitizer cable when doing the final reassambly... /facepalm
Anyhow, I have a replacement on order, so I'm hopeful that when I receive that in a few days I'm back to a fully functional Optimus 2x!!

[Q] Permanent Boot Loop

Greetings,
My internal sd card died slowly over time. It failed to mount on some occasions at first. After a few weeks I had massive app crashes.
Everything I did on the phone (installing apps, deleting files, even doing a factory reset) seemed to revert back after rebooting the phone. I mean I delete some files, and after reboot, the files came back from the dead. Same thing for factory reset.
Installing other roms made the situation even worse, and I had to revert back to stock 2.3 rom.
And since last week, the phone is on permanent bootloop. It won't go into download or recovery mode (it used to activate those modes with 3 button combo before).
I tried the USB JIG method. Built a 301k resistor, connected pins to the usb thingie. It did power the phone on, but failed to trigger the download mode. The phone still goes into a boot loop.
Anyone has any ideas? I don't know what more information I can provide about the issue.
Regards,

No download mode?
If your phone won’t enter download mode, you can try three things:
A USB jig. Don’t pin your hopes on this, they rarely succeed in this scenario.
‘Jump starting’ – You might need someone else to give you a hand for this. Take the battery out of your phone and wait 30 seconds. Now, press the button combination to enter download mode, and with this combination still depressed, get someone to put the battery back in. Hopefully this will jolt your phone into download mode.
Take out the phone battery, and re-insert it, but don’t turn the phone on. Now, plug in the charger while holding the volume down button. Keep holding volume down till you enter download mode.
If your phone won’t enter download mode, and will do nothing but get hot when you attempt to do anything to it (charge it, turn it on), then your motherboard is in need of replacement.
Your options
I’ve seen a lot of people, when their Odin flash fails, either:
Give up. Not a good option.
Flash a .pit file. That should be used as an absolute last resort. There’s a lot to try before getting to that stage! If a flash of a .pit file fails in Odin, your phone is well and truly unrecoverable, and you will need a motherboard (MB) replacement.
Quoted from a quite by Hopper8, try these steps. Can't really do anything since recovery/download mode is dead. If you can get into download mode, flash a .pit file (get all the files ready beforehand). Be quick, since you don't know when your device will die again.

My little sister had the same problem.
But now the phone is complete dead.
Not booting after bootloop.
No customroms ever installed.

[HELP] Redmi 4x won't boot.

Hello,
my Redmi 4x won't boot. I tried to find some solution for this issue, but I can't find it anywhere, so I created this new thread to ask you for your help.
Last night I was out in the city and my phone died because of low battery, so after I came home I just wanted to charge it as usual. Battery logo showed up and it was behaving as always, but when I tried to turn it on it couldn't boot again.
After pressing the power button the splash screen flashes for a brief moment and then it just turn off again. This happens all the time from the moment my phone died. I'm not sure what went wrong here. I can't get it to recovery mode either. So I wanted to do a fresh start and flash it again with new ROM here (Ressurection Remix 6 is what I have now)
I'm able to get it on fastboot mode, but once I try to flash it with MiFlash I get error message like "error:FAILED (remote: Critical partition flashing is not allowed)"
So I looked up for a solution and I found that I need to get it in EDL mode with adb.exe
I tried this solution but with no luck. Phone is restarting but it won't turn on again and the fastboot mode is lost.
I'm not really sure if I have right drivers for it. Qualcomm HS-USB Diagnostics 900E is what I have now. I can't also change the usb debugging mode obviously, so I'm also trying to find some solution for this issue either (is there any chance how to turn it on with adb.exe?)
I think it's softbricked but i'm not really sure.
Thank you for your help

Hi, most likely your battery is faulty. Current draw during Android kernel boot up phase is above 1A whereas only around 0.2A for a working OS, that's why neither OS nor recovery can start when the battery develops high ESR (internal resistance). Do the following test:
fully recharge the battery
do not disconnect the charger
turn it on
Your Android may now actually work again but you must use a short quality cable connected to a 2A+ charger, which will support the battery at boot time - and you can disconnect it later.

Thank you, but the battery wasn't the main issue, because once I was able to flash it through EDL mode to the latest stable official ROM, the battery was on 93% already.
Now I'm stuck with MI logo and powered by android with 3 blinking dots above. I watched somewhere, that it could last for 7 minutes, but for me even the 15 minutes is not enough, so I guess i'm in bootloop.
For some reason my bootloader is locked again, even though I already made the unlocking process earlier before I flashed to Resurection remix 6. My phone doesn't even appear in device manager. I can't even use it as a storage, so I could try to flash it to custom ROM.
I'm not really sure wat happened and how is it possible to brick your phone by just draining your battery to 0%

Ok, phone is alive again. It booted up right after I inersted microSD card in slot. I didn't know this was necessary...

Bootloop and nonstop Restart Issue

Helllo,
My Mi A2 can't boot into the system it keeps restarting all the time. Even when I have tried go to fastboot mode, it goes it, but after several seconds it restarts, so I can'd do anything about it.
I have tried power+up, but "no command" error.
What can I do?
Is there any solution?

Open the phone with screwdriver and short the "test point" ...then when in edl flash the stock ROM ....and anyway after that ..in fastboot boot twrp and flash a zip from the global telegram group or my other posts to restore your persist
If after that your phone still fails to work it is a hardware problem causing this ....

Update:
I have replugged all the cables and while battery was drained I have turned it on again.
It worked!
I even make an update for android. But after some period of time, it started restarting and now I have the same loop.
I have unlocked the bootloader while it was working, but it doesn't help me right now at all.
Phone keeps restarting...
While it was working and charghing, some application was automatically opening and sensor started making some clicks.
When I had the same ecounter with other phones, it was battery fault.
What do you think guys?

I am also facing this issue. Sometime it reboots randomly but other times it works fine. Should I roll back to Android Pie?

Hi! I am facing a similar issue: Suddenly my phone shut off. When I wanted to turn it on, it would shut itself off after ~3 seconds of the boot screen. If I plug it to charge, it would start rebooting every 3 seconds.
I have left it charging for a long time, and at a certain point it stops doing this and shows that it is fully charged. I have tried to unplug it and turn it on after this, but I am getting the same result. Once again, charged it, and tried to turn it on while connected. It turned on, but once I unplugged it (before unlocking it) it froze .
Recovery mode does not work (same result), but fastboot works. Unfortunately I can't flash it as I can't risk losing all my data.
Having said this, I want to know more details about what has worked for you. Did you drain the battery and then connected it to charge?

That seems quite cheap. It's up to you, I guess.
If you want to solve it yourself, you can give it a try to flash it in EDL mode. I have tried it with no success yet.

Question Redmi Note 10 Pro stuck in a boot loop

Today I left my phone in a cab and got it back in the evening. But after I got my phone it was stuck in a boot loop (after force restart - power button press and hold - it will go to battery icon and automatically restart after a few minutes and again goes to battery icon). Please see the video to understand the boot loop. Unfortunately, Developer options of the phone were not enabled.
Can boot to recovery but can boot to fastboot.
Can you please help me to boot my phone back to normal or sideload a ROM via adb.
tia

Was able to fix the issue. Followed below steps,
1. Kept phone until the battery fully drains
2. Plugged into the charger and charged the phone up to around 65% while the phone is switched off.
3. Switched on the phone when the cable is disconnected.
4. This time the phone was booted to recovery. No battery logo anymore
5. From recovery, rebooted the phone. But again it was booted to recovery.
6. Wiped all data and rebooted.
7. Phone was booted to MIUI os but had to set up the phone again from the beginning.

Same problem bro, did u resolve it???

I think your battery is empty. Leave it on power for a while and check if its charging. Maybe the charginglevel is too low for booting up.

I hope it was that simple ..it seems probably like a bad update. My gfs phone did the similar today
The digitizer stopped working, I force reset the phone and boom ..recovery mode - Trying everything but it doesn't work. Wipe surely would work but she has pictures and videos so I'm trying to avoid that. Plug it to charging but she remembers it had like 75% of battery ...geez (hoping for a miracle)
EDIT: Probably this happen from the bad xiaomi update, anyway I did wipe the data and as expected it work without an issue, I'll unlock this phone and ditch MIUI (I mean I did it to my phone Xiaomi Mi Mix 2S from day 1 - I hate miui) ..now my gf has a reason to hate it too

A factory reset could be painful, since you would lose everything on the device. I saw a guy tap all over the back of the phone with two fingers, and boom! The Redmi Note 10 Pro boot normally! I tried it on a friend's phone, and it worked.

Hello,I had a kind of a similar thing.
I left my phone to charge and when I was back it seems to be stuck in a boot loop(MIUI14)
Well,I tried to force restart but the same.
Before I go to recovery mode,accidently,I putted the phone in fastboot mode.I restarted it in the try to go to recovery mode but the phone started normally.After boot,it's shows an update compete message,so te problem was from an android security path update whatever.

I have important apps on the phone and I wasnt thinking about a factory reset anyway but hopefully it worked in that way
