[Q] Possibly bricked MT4G after attempting root with visionary 14, please advise

So like the total noob I am I tried to root my MT4G using visionary v14 (I think, can't start my phone to check) without having all the appropriate files in place. This caused Visionary to crash when I rebooted my phone. I gave it some time and then being unable to restart using the power button I pulled the battery. After that the phone has been totally dead, I can't get it to turn on at all or even recognize that it is plugged in. I have tried starting plugged into my computer, unplugged, plugged into charger and all possible combinations of SIM card and SD card in/out. Nothing. I am very afraid I bricked the damn thing, but I'd appreciate any input... especially since the the replacement would come with Gingerbread and I really don't want to have to go through the whole downgrading crap.
Thanks.
Cheers,

Hello RobotPenguin,
I'm not a specialist (actually, I'm quite a newbie here) but most of bricked device can boot to the bootloader or at least display the splashscreen.
Are you sure the battery is alright and correctly installed ?
Regards

I assume so. It was fully charged when it crashed and the "tech" at the T-mobile Store swapped out the battery in my phone with the charged battery from her functional MT4G to no benefit.
Thanks.

I believe this may be my answer... damn.

Well, lets check to see if it is bricked
1: pull the battery out
2: put the battery back / put on the battery door.
3: hold the power button and the volume down rocker.
* the device should boot to a white Screen with three Android Skateboarders.
**If you get to that screen it's a good thing.
**if you don't then you are SOL.
4: try doing a factory reset from that white screen
5: reboot the phone.
If it still doesn't boot you need to load the PD15IMG.zip onto the root of the SD card and start over.
If the PD15IMG.zip doesn't load (given the MD5SUMs match), or give you any errors at all you are SOL.

I got that far and no recovery screen... so I guess I'm SOL. I guess I'll just wait for the new one to come from T-mobile and do the whole downgrade bit so I can root the phone. Pain in the @$$, oh well.
Thanks for helping me out.

Most probably you've attempted to flash Engineering HBOOT ("root.sh" way of rooting) and failed, which left your phone without bootloader.
You can't recover from it.

if holding power and volume down does not get u into hboot then u r screwed. Hopefully u didn't cheap out and got the insurance for your fone. If u do have insurance on the phone then call asurion (the insurance company t mobile uses) and tell asurion that u lost your fone (say u left it on the bus).then pay your deductible and get another fone.

I have rooted 2 myt 4gs and they both crapped out for 3-10 days then magically started working. The whole time they were down all they would do is flash an orange light and vibrate 3 times when i powered on or vibrate 5 times and flash green when i tried bootloader. I pulled the battery out and left it out the first one was 3 days and the second time was close to 10 days then bam they came back up

Thanks for the info guys

Nook -completely- unresponsive/truebrick,full battery,unrelated to Rooted Forever scr

Hello all, I'm curious to hear your thoughts and advice.
My nook is completely unresponsive. It is not stuck at rooted forever.
In fact this has nothing with a root attempt/reset/restore/power on.
I had done a a fresh reset/root with touchnooter about four months ago and was happily and smoothly reading for about two months. I then got busy and put the nook down, did not touch or use for about another two months. I tried to use it about a week ago but found that it had run out of battery in sleep after the two months of disuse (not surprising). I put it on charge overnight and everything booted right and functioned well once it turned on, except that the battery indicator in the statusbar showed a "?" and the battery info in system info showed 100% "unknown". After alot of fruitless research I put it down with the intention of reset/restore/root when I had the time.
I just picked it up this morning and was faced with the expected "Press then button below to wake up your NOOK" screen. But when I pressed the "n" button nothing happened. Obviously holding the "n" did nothing as well.
I tried to power it off and on- nothing
holding power for 20- nothing
power for 30- nothing
8 failed boots- nothing
left right- nothing
left right power-nothing
random pushing and holding of power- nothing
all these with mem card in and out- nothing
all these plugged usb- nothing
all these pugged ac- nothing
I let it charge some more- nothing
None of the buttons do anything, the screen stays inevitably at the " press the n button to wake" screen. no activity whatsoever except that when It is plugged in, the green light shows. NO ORANGE LIGHT... it is fully charged by both usb and ac.
It is not detected at all by windows anywhere.
In Linux- lsusb, bklid, and df -h yield nothing. My nook might as well be the invisible stupid ereader.
I did not drop it, sumbmerge it, perform magic around it... It has been sitting on a shelf doing nothing.
To repeat, the only thing my nook does is light up green when plugged.
It is unchangeably stuck on poe's face...
If this isn't true brick, I don't know what is.
I'm exhausted. Any ideas? I appreciate the help.
Best,
Thomas

i don't know. i just know my dog ate mine and i'm now in the market for a new screen, so if you don't get it working sell me the unit and get some money for yourself to purchase a new one =D
or you could google the disassembly instructions and try unplugging the battery, not very hard to do. could be of .. some help perhaps?

I would definitely take you up on your offer, but i'm still under warranty.
However, I would still like to have my original, and figure out what is going on and why it happened.
Ideas?
Thank you.

if it helps let them know in the tread that you had same problem. they are wondering whether it is due to host mode

[N2E]: After automatic update to 1.1, Nook Touch Screen absolutely DEAD--Nothing Work
THIS WAS A POST FROM ANOTHER SITE AS TO MY PROBLEM:
I was reading on my N2E last night. I put it down for about 30 minutes and when I came back it was displaying the default "Authors" screensaver (I had switched to the Nature photos) and asking to slide to unlock. I thought, "Oh, the new software update must have downloaded and installed. I'll check it out." To my shock, the touch screen was completely unresponsive--no amount of swiping would unlock from the screen saver. I let it set for a while longer thinking perhaps the softare update was not yet finished. No such luck.
As a result of the new update, my NOOK is now completly DEAD! I tried powering off, but couldn't do that because you are asked to confirm power off on the touchscreen, which no longer works. So, I looked online and tried the soft reset/reboot by holding down the "Home" or "n" button and then pressing the power button for several seconds. Great--it started rebooting...and came right back to the "authors" screen saver and asking to swipe to unlock. I tried this rebooting process several times, always with the same result: back to screeensaver mode with completely unresponsive touchscreen.
So, looked at the online technical troubleshooting discussion and helps and decided to try a downloaded manual install of the software update. Plugged my NOOK into my computer and it recognized it. So, I downloaded the manualo software update and dragged and dropped it onto the NOOK as directed and sure enough, it started to reboot itself. I thought, "whew, maybe this will fix it". NOPE--came right back to the locked screensaver, with no mention of attempting to update software, and the touchscreen is still dead. (By the way, all of this was done initially with the NOOK showing about 94% charged, so it was not a battery issue.)
Reconnected the NOOK to my computer and the software update file was gone from its home directory, which implies it did something with it. So, I tried repeatedly to install the software update manually, always with the same result: NOOK comes back to locked default "authors" screensaver wtih a dead touchscreen.
Looked online for B&N technical support again saw that others had this problem (though only found a couple references). Found the instructions to do a factory reset and reluctantly tried that, desparate to make my NOOK work again, but frustrated that if it did I would have to rebuild everyting on it and download my 400+ B&N book library all over again. But, guess what, factory reset just comes up to the "Welcome to your all-new NOOK" screen (sounds like progress), BUT the touchscreen is STILL dead, so I can't hit the "Next" button onscreen to proceed with setting up my factory-reset NOOK. Tried rebooting again (as this seems to be the only solution offered in the online tech support) and now it just keeps coming back to the "Welcome to your all-new NOOK" screen with a dead touchscreen keeping me from doing anything.
So, now I am taking it back to my local B&N store in hopes they will exchange it for a new NOOK.
I really want to see a feature to disable automatic updates in the future. I specifically didn't download and manually install when the update came out, figuring I'd wait for the automatic download to give time to B&N to work out the bugs and perhaps issue a patch (as they have done in the past for the N1E). Instead I get no warning about the automatic download (happens while I am reading and set the NOOK aside for 30 minutes), and then the update KILLS my NOOK.
I am not a satisfied NOOK customer at this point.
MY POST: (from the that site)
Not Sure how to do this post or whatever, but I was happy until the update and everything that happened to you is the same with me. This is the first post that describes what happened to me. I'm out of warranty and refuse (and can't) to buy another one of these. If their updates can do this, I'm not sure I want to sink another $100 into the shareholders pockets. I'd really like to know if anyone knows what may be wrong with it.
In addition to what was already mentioned, I took the battery out several times(which seems intimidating but very easy but voids the warranty) and took it completely apart cleaning the screen very well with water and another time a glass cleaner. I tried rooting also. Not sure of what to do now. It seems software related due to working fine until the update. Still at the "Welcome to your all-new NOOK" screen with unresponsive screen. I wasn't sure if the last sentence from B&N was a personal message to me welcoming me to the "new" state of the my nook.
Thanks for any help from anyone.
Thanks.

Identical problem.... and no fix..
It is a shame you got no solution for this. and the worst, you are not the only one... it happened exactly the same with my Nook ST....
Hopeless...

The factory restore does not actually fix every possible problem with your Nook.
If your Nook responds at all, try to boot it up on an SD card like ClockworkMod or noogie.
At least that way you can see what is happening.
The partitioning might have become corrupted which the "factory restore" does not touch.
If no response with anything, try disconnecting the battery.
You might also try booting over USB using the techniques in rooting the new white glow.

Hello I was wondering if I'm just screwed I bought 2 nook simple touch, one for me and one for a present to my mother for her birthday on march 16. I bought them at best buy for $40 a piece on January 30. I used mine and was perfect but when I tried to set up my mom it wouldn't load the license agreement, always got stuck or reboot or something, so I loaded cwm on an sd card just to play around, tested on my nook and was fine, then put it on my moms nook booted once then I didn't press anything and turn it off then I load the image but when I tried to boot again it got stuck on the load screen and wont do anything, no reset sequence will work with the sd card on or off the other nook boots with this sd card. at the end I exchanged with my mom she is happy with her nook an I have a useless unit do you think they will exchange it I didn't rooted it or did anything to it but has the n cwm splash on screen forever. I'm in Costa Rica right now and wont return home until May do you think I'll might be able to exchange it or should I just try to repair it.

I'm glad that your mother got the working one!
You say that that one will boot on your CWM SD card, but yours won't?
It may be hard to get your unit exchanged with a conspicuous screen on it, even if it's not your fault.
When you plug it into your desktop is there any indication of a new USB device found?
If it's charged and no amount of the power button gets a reaction, I'd open it up.

any news???

There are times when a Nook gets in a mode where it won't accept a charge.
Opening it up and disconnecting the battery for a minute might fix this.

When this worked for you did the light turn orange right when you plugged the battery back in? I just took the battery out, plugged the nook into a charger, and with it plugged in plugged the battery back in and the light stays green the whole time yet I'm not able to use the nook at all.

My nook second generation is not responding to my touch I tried everything to get it to work and I eventually got it to completely power of what if it does not work when I turn it on what should I do

It could be power/battery problems.
Check to see if it makes itself known when the USB is plugged in.
If it reacts at all, that's an indication of life.

[Q] Nexus 4 Damage Help

So first some back-story, I'll get right into it. I recently dropped my phone in some water. As soon as possible I dried off the outside, and let it sit. That was the only thing I could do at the time, I had no rice, no tools to open up the phone, anything. I ended up with a solid red light, and everything unresponsive.
The next day I got some tools to open her up. There was pretty extensive corrosion to the motherboard, so using some alcohol I cleaned it all off, rinsed it, and let it dry. I also took apart everything else and cleaned any corrosion. The inside looks brand new. However, this isn't the point of the thread.
It appeared my cleaning helped quite a bit. Upon re-assembling and plugging in, I immediately got a charging sign on the phone. However, after trying to power on, I got no response. Additionally, The charging signal went out after about 20 seconds, and the whole phone became unresponsive again. I can do this process as many times as I want, but the same thing happens every time.
So I tried a different approach. First I hold down both volume rockers plus the power button, and plug it in while holding them down. This puts the phone into "download mode" However, once in download mode the phone is, again, unresponsive. After plugging into my laptop, my computer recognizes the phone, but not as "Nexus 4," but as "Full JellyBean on Mako."
Is there anything I can do about this? I've heard about drivers being able to be installed when in download mode, but I would not know what these are, where to get them, or how to install them. I really don't mind if my phone never works 100% again, I doubt it would. I just want to be able to get into the storage so I can recover some of the files I lost.
It's also probably worth mentioning I have not gotten a solid red light after the clean. Once in a while I will get a blinking red light after plugging it in, but after less than a minute it stops and goes through the charging/stop charging phase I'm so familiar with. Any help at all would be appreciated, and thanks in advance.

The charging block and/or battery could be wrecked, for safety reasons and because it will probably become faulty soon you should change the battery anyway. If the charging block is broken flashing your phone could fail. It's also possible the board was irreparably damaged, but it's probably worth a try as the parts aren't too expensive.

After trying to figure more things out, I kept it plugged in for a while. It appears my battery actually holds at least a pretty good charge, as the indicator is full when I plug it in now. However, I don't know what you mean when you say charging block.
Also, I seemed to determine my power button isn't working either. I always thought no response to pushing it meant there was something else going on, but I am able to put it into "download mode" by just holding down the volume rockers and plugging it in. Is there a way to turn on the phone another way besides the power button? Also if not, will buying another power button fix the problem? I don't want to buy one then later figure out the reason it wasn't turning on was just a board problem, and not a problem with the button itself.

You can short the power button with a screwdriver or something should turn the phone on., By charging block I mean the secondary board that the micro usb port is a part of, it can be replaced fairly easily if necessary.

With a screwdriver? Enlighten me, I'd have no idea how to do that. If I had a faulty charging block, then my phone wouldn't be able to charge correct? My phone was plugged in for a while in download mode, and it gained a full charge from a relatively low charge. I also took the block apart and cleaned any corrosion, so I think that's still functional.
Some more progress, upon further attempting to turn the phone on, I was able to get it into fastboot mode. When plugging into the computer it is recognized, but as just "Android." I will type out what information is displayed here, minus serial number, as a new member cannot submit links in posts apparently.
FASTBOOT MODE
PRODUCT_NAME - mako
VARIENT - mako 8GB
HW VERSION - rev_11
BOOTLOADER VERSION - MAK0230d
BASEBAND VERSION - M9615A-CEFWMAZM-2.0.1700.98
CARRIER INFO - None
SERIAL NUMBER -
SIGNING - production
SECURE BOOT - enabled
LOCK STATE - locked
Also, fastboot at the top (as far as I know) usually says "Start" or "Recovery Mode," but mine says "Restart bootloader." When I try switching with my volume buttons, nothing happens.

Another update, just in case anyone is still listening..

Now that you're at this point, have you attempted to flash the phone with a stock image? I'd be weary of what the other poster said though and ensure your USB connection is holding steady because you don't want it dying half way through a flash because then you'll have a brick.

I have tried actually. I used the Nexus Root Toolkit v1.8.0 to try and flash it. At first it wouldn't find the device, but through device manager I manually installed the usb_driver onto the phone. After this, the toolkit was able to find the phone. I attempted to flash the image, but it ended up staying in fastboot mode. The program then suggested I try to enable "force flash," which I did, and this time it was never able to finish because the phone tried to restart, but went through that "charging to unresponsive" state I described in my first post.
Upon trying to flash it normally again, it looks like maybe the phone has to be unlocked to do this properly? I then tried to unlock with the same program, but in order to do that, I need the power button to confirm I actually want to unlock the phone. So yet again, I need that power button working.
Any ideas/suggestions/solutions would be amazing.

Jellybean on mako means that your phone is in lgnpst/qcpnst mode. Looks like something failed to start and made the bootloader trogger that mode

Problem is the power button doesn't work, and the flashing fails. It looks like the flashing fails because the phone isn't unlocked. To unlock, I need the power button. Kinda stuck.

Is my Note 4 dead?

Hello dear community,
I'm posting there because I have some doubts about my phone and i'd like some answers from you.
1 month ago, I was charging my phone. When it reached 100% battery, It was fine but the problem is when I was trying to press "power" to turn it on but It didn't want to. So, I removed the battery because I couldn't even turn it off. When I tried to restart it again, it didn't want to. No reaction to the "power" button.
I followed EVERY tips on Google but none worked. I also tried to change my battery but nothing. I tried also to connect it to my computer, it was detected but my phone didn't turn on.
So, I guess my phone is dead unless if there is a solution to make it working? Also before that, my phone was becoming very laggy and when it had a small lag, it was turning off and was rebooting.
Thank you in advance for your answers.

•Reason: "... when I was trying to press "power" to turn it on... it didn't want to... When I tried to restart it again, it didn't want to. No reaction to the "power" button."
—Seems like you're gonna have to find another Note 4 and replace its motherboard with the Note 4 whose power button doesn't work anymore after 5 years.
But before spending, I would like you to try this method from a Youtube comment:
"... you'll just have to keep the charger [cable connected] on [your phone] while you take off the battery, and put it back after; then, remove the charger quickly..."
—————
2nd claim: The screen no longer works
•Reason: "I tried also to connect it to my computer, it was detected but my phone didn't turn on."
—If the phone is charged, seeing nothing but blackness, but you still see an emitting LED light on the top-left corner, that's a sign that it still works, just not the screen. So I would suggest that you buy a new screen and replace it with your old one. If you think you can't, then go to a phone repair shop and let others do the repairing.
—————
3rd claim: The motherboard is dead
•Reason: "... before that, my phone was becoming very laggy and when it had a small lag, it was turning off and was rebooting."
—The motherboard might be dead if these are happening, but I don't think this is the right reason unless the first two conclusions are proven to be true. If the first two conclusions are proven to be false, then the motherboard is dead, and you may either buy another Note 4 motherboard or get a new phone.

Thank you for your answer.
To answer you clearly about all the points you clarified, there is no led light appearing when putting it on charge and I also tried the "Youtube comment" but nothing.
So I think, the motherboard is dead as you mentioned. I just don't understand how it died after a charge but as I saw on Google, it's a general problem on Galaxy Note 4, so I think i'm not surprised at all. It's been since 2015 I had it.
Thank you for your time and to have solved my doubts about the death about my phone.

Hello dear community,
I'm posting there because I have some doubts about my phone and i'd like some answers from you.
1 month ago, I was charging my phone. When it reached 100% battery, It was fine but the problem is when I was trying to press "power" to turn it on but It didn't want to. So, I removed the battery because I couldn't even turn it off. When I tried to restart it again, it didn't want to. No reaction to the "power" button.
I followed EVERY tips on Google but none worked. I also tried to change my battery but nothing. I tried also to connect it to my computer, it was detected but my phone didn't turn on.
So, I guess my phone is dead unless if there is a solution to make it working? Also before that, my phone was becoming very laggy and when it had a small lag, it was turning off and was rebooting.
Thank you in advance for your answers.

Put in cold fridge for 30 min without battery, then try to turn it on. If not, try the cardboard method under the emmc chip (search youtube)

Is this a serious thing ? (fridge)

I did the oven trick on my n910t. I left my phone stuck in the grill of my truck when I changed the brakes. I took it for a test drive and ended up running over the phone. Me being a noob at the time didn't know the AT&T Note 4 would not unlock Bootloader for custom roms or custom recoveries. I purchased the AT&T Note and was sorely disappointed there after. Flash 2019 I still have the motherboard for my note that I ran over. I can only get in to go into download mode and only when it was plugged in. I flash custom ROM or custom recovery and it would say would pass but it would just boot loop and boot loop. So I read somewhere where you can put it in the oven for around 5 to 6 minutes at about 200° and that it would settle any of the cracked solder that be around the emmc or anywhere else on the board. So I tried it. I stuck it in two different times at five minutes a piece, pull the board out and let it set for a day. I installed the board just a little while ago and she fired right up. It's amazing

I've recently replaced the motherboard on my N910F with a used one bought from AliExpress. As it's used I've no idea how long it will last but for £30 was worth a try.
It was pretty straightforward replacing the motherboard using one of the tear down guides on YouTube.

M30s does not boot - stuck at very first screen

Hi all,
my Gylaxy M30s rebooted itself yestarday, and now is stuck at the very first screen (the one showing "SAMSUNG Galaxy M30s" in the center and "Powered by android" at the bottom).
Vol down + power results in a reboot attempt (screen goes black, vibration), but the phone is stopping at the same screen again.
I am not able to turn the phone off.
Switching from Vol down to Vol up immediately when screen goes black does not enter recovery mode.
Vol down + power while charging sometimes leads to the charging symbol being shown on the screen, but without the percentage in the middle.
Charging over night did not help.
The phone cannot be connected to a Win PC.
Any suggestions what I can try?
Thanks,
Alchemist

Try volume down+volume up and while pressing those buttons, plug your phone into your computer. Tell me the results of that.

Nothing happening...

I mean trying those combinations immediately after using power+ volume down to reboot.

What did you do with your phone? Died suddenly when normally using?

Yes, phone died during normal usage.
Ah, I see - a screen comes up warning me that downloading a custom OS might harm the phone.
Also, the PC makes this "USB connected" sound when I then press Vol up, but I do not see a new drive connected, I think.
I am slightly optimistic now?

Press volume up.Then install Samsung usb drivers(search on Google)

Ugh, just wanted to do this, but now the phone is completely dead. No response to any button or charging. Will hang it on the charger for a few hours, but my optimism is gone...

OK, now it works again. I am in the screen with the colourfull stuff and the phone waits for some download.
Driver is installed on PC. Is there anything supposed to happen - the phone is still not accessible via PC, or is it?

Install Odin (search in Google 'odin samsung' and download)
Download stock firmware(android os) at www.samfw.com , after downloading you will see files like AP-M505xxxxxxx.tar.
Select, from the stock ROM AP-M305xxxxx.tar for AP in odin CSC-M305xxxxx.tar for CSC, and so forth then click start .

OK. All data will be lost, right? Is there some way to access the internal storage to rescue some files before flashing the new firmware?

Sorry to tell you that you cannot have data restored bad news for you sorry

Sorry. If you only see one file(make sure it is .tar or .tar.md5 file) after you extracted the .zip firmware, install it to the AP slot.

Any chance I could fix this issue with tools like dr.fone, UltFOne, ReiBoot?
I do not have any experiences with these - no idea if the just want to make money with desparate customers? ...

These could possibly brick your phones even more ( anyways flashing with Odin could also brick your phone). However, it in some cases can fix your device.
If you HAVE to have your data back and you don't mind paying, visit a service center and tell them: 'Hey my phone died and i HAVE to have the data back '.(I know, your warranty is expired probably, but they might still do the things for you with paying.)(if those stores closed during lockdown then I don't know any way to fix it.)

OK, another thing I have observed: The screen goes black after about 30 sec to 5 min when not charged - the shorter it was charged, the quicker the screen goes black. Buttons do nothing when screen is black. When reattached to charger, phone tries to boot and is then stuck at said screen - no button pressing needed for the phone to try to start. The longer the phone has been without charger, the longer it takes until the phone tries to boot.
Maybe it's just the battery that is dead - or would the phone with a dead battery boot normally when attached to charger?

If that is the case, open up your phone, put in a replacement battery, and try to boot up(yes, you need to. it will be a frustrating process.). Your phone could be having a faulty battery and nothing else, to cause this issue.

Im having the same problem mentioned above. The samsung service centre says to replace the motherboard which costs almost half the price of the actual phone..

Truth to be told: The guy in the repair shop opened the phone and wanted to change the battery - when he saw that water must have come into the phone, corroding the motherboard. So yeah, all data lost, but... no backup, no mercy. I now have set up a NAS for all computers and devices in our family... ;-)

If it really is a hardware problem then the quality must have been really bad.
