This is not quite as insane as heating your phone in the oven, and you probably won't want to do this but...
Try bricking your phone, and then sending it to Samsung. I did, and I now can use the 3-button grips to enter download and recovery mode.
If I had the option, and prior knowledge of the importance of the 3-button method of getting into recovery or download mode I would have been more careful when I got my phone. I wasn't, and I purchased a phone with a disabled 3-button recovery. Darn.
Because I have flashed firmware onto different devices without any past problems, I elected to flash the Bell JH2 firmware (from JG9, using Odin), despite the lack of recovery options. In truth, I had little choice, as somewhere along the customization road I messed something up badly enough that continual force close messages made the phone unusable.
Obviously the flash failed, and I was left with the black screen of death.
I took the phone back to Bell, and they sent it along to Samsung (last Wednesday). Today I got the phone back and, just on the off-chance, tried the 3-button grip to enter download mode; less than a second later I was in download mode. I can now enter download and recovery mode with ease. Samsung also upgraded the phone to JH2.
I could't find any mention in the forums that Samsung would enable the 3-button features, or that JH2 enabled the features, but it appears that one or the other has done so. Draw what conclusions you will.
Before anyone asks: I have confirmed that the phone is the same phone (the s/n and imei stickers on the phone match the stickers on the original box, which wasn't sent with the phone to Samsung, and the phone remains sim unlocked), and I employed the same 3-button procedure this time as in all previous, failed attempts (actually I tried every trick of timing, grip, battery insertion, sim card and xd card in the previous failures).
wow! you got the phone back so quickly?!?!?!
it's been more than 5 weeks already for me, and i still don't have my original phone back
good thing i bough a few...
Yeah. I was a little surprised myself.
While I didn't like the sinking sensation I experienced when I bricked the phone, all-in-all I am not unhappy with the result, as I expected to have to wait a month or two before I would be able to unlock the phone, cancel the Bell plan and use the phone with my Rogers.
Now I have a fully functional, unlocked phone after less than two weeks of ownership (yep, I bricked the phone 4 days after I got it - I guess I should be more appreciative of the features of my former HTC Hero )
i beat you, i bricked my first SGS on the 3rd day of owner ship trying to flash Froyo Alpha, knowing i had a disabled 3 button phone
I am happy to hear you got your phone back so quickly. Mine was sent off by Bell on Wednesday, it died on its own accord though, no rooting or anything.
This loaner N97 is killing me, why on earth these phones are so popular in other parts of the world boggles my mind. Its most clunky slow ass OS I have ever used.. resistive touch screen on top of that makes me want to kill something.
Note 4 wont turn on, "cannot boot normal" and "downlaoding target, dont turn off"
Its a Note 4 SM-N910F, Android 6.0.1, BB N910FXXU1DPE2, kernel 3.10.40-7733605 [email protected] #1
i feel I have tried everything... History:
Phone has been working fine for a year, upgraded to 6.0.1 no problems about 2 or 3 months ago. no new apps installed. Last week it started getting very laggy, keyboard strokes took for ever to register. I thought, ok, time to to a factory reset to blow out any old cobwebs. Did it via the menu. However the phone froze midway thought. I left it for an hour and then pulled out the battery. I popped it back in and it performed the reset without me having to press anything. Cool, thats good I thought.
Now I was going to change the battery, so I powered off as normal and put my other 2 week old original samsung battery in, and it would not power on. After a few reinsertions it powered back on. I though i have to do another reset. So I tried, and it would not reset. It just died. I cant restart the phone, it dies. If I shut it down normally. it wont turn on back on, I have to take out and reinsert the battery multiple times, holding down the powerbutton between to discharge. this can take up to 10 tries now. Sometimes it will go th the unable to bot in normal mode and "downloading , do not turn of target, but it will stay there for ever, more than an hour.
Every 15-20 tries it would turn on, let me get in via pin, only to start freezing up within a min, and then die again. Somewhere I read that a guy hada similar problem, and he used wakelock and that worked, on level 4. I managed to download that and used it, and hey presto, it works!
Now I had to power down the phone for a reason, and it took me about 30 min of battery and powerbuttonholding before it managed to boot up, and I was quick enough to start wakelock on level 4.
It wont boot in to safe mode, it wont boot in to recovery mode, it wont boot in to the factory reset mode. Its the same with either battery, and different cables.
Any ideas what i can do here, or what could be wrong? I havent gotten it wet or banged it.
I am having the same exact issue on a N910A. Phone was functioning correctly and in December it started getting really laggy. Performed various resets, purchased new battery. Still laggy. Up until two weeks ago the phone was slow but now it will not power on . The phone will not charge as well.
Mine did same, 6 months old, not rooted stock firmware. Locked up yesterday, couldn't do anything. Pulled battery and restarted. Samsung logo comes on screen goes black for android boot then it hangs with blue led flashing. Nothing I do gets it past that point. Tried safe boot but it doesn't fully launch with correct button combo and volume up. In the end I re-installed firmware using Keis. All went well, everything as per youtube tutorial. Except one thing, at end of download phone didn't re-start. Still can't get it to boot, any ideas?
Edit: Lock up didn't coincide with any new apps being loaded or updates of existing. Only change was a week ago which was an automatic update of the stock firmware (Lollipop)

are you still under warranty? i sent mine to a samsung center, the guy recognized the problem as the motherboard, said I wasnt the first. That was 3 weeks ago, they are STILL waiting for the parts. They say the Samsung factory are way behind with repair parts, etc etc. I am hoping it will go under warranty. Ill update when I know!
I've been having the same problem that started yesterday morning. I've tried a few different solutions but nothings worked, I get the feeling that my phone is dead and I'm not in warranty either. I'm going to approach Samsung but my guess is they will want more than the phone is worth to repair it. I've read about so many people having the same issues, its horrendous engineering on Samsungs part considering how much their phones cost to start with

Your guess is probably correct and I totally agree with you. I seriously think manufacturers do not want their devices to be problem free for more than two years. Probably why they have stopped making phones with batteries that simply pop out.

Definitely...surely it couldn't have been that hard to make a device with a battery that was still removable on the newer phones. It's frightening how many forum posts I've found with people having their phones just brick out of nowhere (and that's just the note 4). I've given up trying to fix mine, I've tried every method I could find and nothings worked. I can only assume that this problem is simply the motherboard of the phone not working anymore. I'm not even sure what phone to buy now but it certainly won't be a Samsung.

If you do not care about the camera thera are a lot of rather affordable options which can be tossed in the bin when they start malfunctioning and if their warranty has run out. If you care about the camera being as good as the Note 4's than the range of phones you can buy is quite limited.

If you are able to boot it into Download Mode then you should Download Stock Rom file for Galaxy Note 4 from Sammobile and Flash it through Odin..
Everything will be OK... ?
Unfortunately, SAMMOBILE does not have the SM-N910A firmware.

I think the camera on the note 4 is absolutley terrible. I might even go so far as to say the pictures are unusable. the applied noise reduction renders everything splotchy, colors are off and its not sharp at all. and Im not talking dark conditions here.
Anyway, my phone was repaired under warranty and is back to working as it should. It was indeed the motherboard, so if you have the same troubles I had, those are your best bets.
I don't think replacement via warranty will be available. I will attempt to power into download mode and verify if I can get it back up and running. If not, a good ole paperweight.

Sounds like the problems I have: with my first N910F: started with lagging apps / freezing, then random reboots now and then, eventually giving error messages when booting. Finally, now it will only start after the battery has been out for at least 30 minutes, but hangs on error message. When pulling battery out and putting back in it, wont give a single sign of life. Since I was just out of warranty it has been lying around, and I bought a second hand N910F for replacement, sadly its starting to give the same errors too and is just out of warranty too (its currently still working, but with freezes / reboots / and already a event with boot error).
I read It could be memory chips or some power chip on the motherboard, appears to be a common problem. So.... Last month I bought a new motherboard on ebay (chinese delivery, 80€). Received it last week and put it back in; phone is back to life. (putting it in is a very simple task, with iFixit teardown / guide)
Anyway, I love the Note 4 for performance / size / looks, and have been Samsung fan for a while, but this recent breakdowns and information that it is fairly common, has diminished being a fan fairly quickly and I guess the Note 4 will be the last Samsung device for a while after this new motherboard breaks down as well

My phone is also random Rebooting
It also shuts down at 25% of battery remaining, Have you also faced similar issue?
Download the app "Wake Lock" and run the Partial Wake Lock option. Apparently the updated software impacts the CPU. For the restarting issue, put it in the freezer for a couple minutes. You may have to take the battery out once, but it has worked for me every time.
This looks very much like the issue reported here:
https://forum.xda-developers.com/no...-error-fix-t3434335/post72944466#post72944466
There are temporary fixes (wakelock), but ultimately this is a harware issue, and the fix is a new motherboard.
I think that underlying it is a problem with heat affecting the eMMC chip or its connection to the motherboard.

Hey can u pls get me the stock firmware for n910gddu1dpb4
You might find this interesting. Since I couldn't get mine to power up at all, I called Samsung tech and they quoted me $75 to fix it and they would pay for shipping. I figured it was better then getting another phone off Swappa. 2-3 weeks later i get an email that they are repairing it under warranty at no cost to me. I got a refurbished phone since i know my IEMI number was different. they didn't explain why. Anyway, I got lucky i guess.
So I have an LDU Edge that was given to me and I am not sure if there is anything I can do with it. I am aware I cannot make calls, that is fine. Basically all it does when I power it on is flash a crazy amount of colors and looks pixelated. You can try and click somethings in the background but the flashing prevents it. The is nothing wrong with the screen and I talked to a Samsung rep in the past about it and he says he has seen them do this but had no knowledge what to do. Is there anyway I can get this to work so I can at least have a wifi device? A new ROM or some other option?

Hi,
I have also got a Galaxy S7 LDU. i am thinking what if i replace its motherboard, will it be a full functional cellphone or it lakes more parts or something..? i can find a completly working motherboard for s7 out of a damaged s7 cellphone. but i am not sure if the demo model i have will work or not like a cell phone after replacing motherboard.
Thanks
Sounds like somebody's turned on 'Show surface updates' in developer options. Basically what happens is every time you touch your screen, it will flash very quickly bright colors. Turn it off and you will fix the problem.
I have tried that to no luck. The always on displays fine but past that is no good.
It will recognize on my pc but since I can't see the screen but for a second I can't get to download mode
I have a S6 LDU that after trying several different things I managed to disable all the demo functions, loops & resets on & am now using it as a Spotify player on an old stereo. Still boots with the LDU splash screen but is running well. Never experienced any screen issues like the OP described, is it possible you have a faulty unit?

Not sure. Always on display works. Boot screen works. Got to be software.
I'm in college and I recently busted my little LG HD Tribute and I decided I would look at the market for a new phone.
One of the new college students fixes busted up phones and sells them so I went to see what he had.
He was selling a brand new Galaxy S7 Edge for 50$ and I thought it was a steal, so I looked at it and it was working well for about 3 days.
I had it turned off charging the other night and I went to turn it on and it began to flicker the Samsung Galaxy Edge screen it shows whenever you turn it on, and just kept flashing. and does literally nothing else. I didn't know what to do, so I tried to reboot it in recovery and all it does is flash "recovery booting" and that's it. So, I can't even get into the BIOS settings of the phone to try and reset it to factory settings or anything like that.
The only thing I can get to pop up is the Custom OS Downloading screen and the "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC Software." screen. So, I downloaded the Smart Switch PC program and ran it, plugged it in and it doesn't recognize the S7 Edge as a supported device. I tried changing USB ports and all, but it just doesn't recognize it. I tried the Emergency feature and that doesn't help either. Even with the SN and the Model ID it still can't fix it.
So I'm guessing it updated while I was sleeping? And something went wrong? I don't know, I didn't physically buy the phone from the carrier myself so I don't think I can just walk into T-Mobile and ask them to help. I'm not sure what to do. Any advice would be wonderful.
Have you tried reflashing everything with odin?

"selling a brand new Galaxy S7 Edge for 50$" a phone that cost around 700$?
The fact that it was sold "brad new" for 50$, didn't trigger some warning light in your brain?
Your s7e is no more than a cheap replica of the original, so "good luck" with the fix!!!

I don't think it was brand new. Because it only started acting weird just after three days. The screen would never flicker only because of an update, so it is definitely a defective phone or a fake one because no body in this world would sell such an expensive device for such a low price, considering that it costs more than 700$ brand new.
It may have been a brand phone, but since the guy according to you sells refurbished phones.
In your mind you should of known, he may have worked on it because it was defective for some reason.
To get it for a cheap price.
Not even defective refirbs would sell for that cheap.. most likely a fake goophone s7 there less than $100 New and they don't last long at all
Post some pics of it :good:

^ That is the album everyone has requested.
It's spaced out because of spam filter xda-developers website has, so just add period.
I went back to the guy today and he admitted that he had actually stolen the phone from his step dad which makes a ton of sense.
This man had stolen the phone and apparently couldn't get into his step dad's Google account so he flashed it with Odin himself and that's how he got it working. He said he couldn't keep the phone due to his step dad would eventually found out he had it but honestly, I don't want the phone knowing this now. It's hot, and it's almost a brick. I seriously feel like a criminal having it, but I spent my work-study money on it and if I'm going to have it in my possession, I want it to at least work.
I left prior to him telling me that he had stolen the phone because I was disgusted and frankly I don't want to associate with this guy knowing this, even if he was honest...
I took it upon myself to try and fix it. I have tried flashing it with Odin myself like one of the users have suggested using the SM-G935T that is on the back of the phone as a reference for downloading the necessary files for the phone's model.
Every time I run Odin while it's plugged in saying it's "Downloading Custom OS" I get the error message: FAIL! (Auth) in Odin.
I don't know what to do.
Any advice would be lovely.
Thanks in advance.

I did, it was installing it for like 5 secs then after a few logs it says FAIL! (Auth) and that's it lol.
I put it in custom os download mode and all, tried Odin. idk
I recently bought a "soft bricked" Note 4 (N910F, Snapdragon). Seller claimed a friend of his wanted to flash a custom ROM based on a newer Android version, however that failed and it only boots to Recovery and Download mode since. So he wanted to sell it since he's not experienced with phones. The listing actually shows a photo of the phone in download mode and one in recovery mode.
After I got the device, I plugged it in to charge the battery and to my surprise, nothing happens. No charge LED, no charge animation. I tried to get into recovery mode (volume up, home + power) and download mode (volume down, home + power), with USB cable attached and without, still nothing. If I plug it into my PC, it's recognised as Qualcomm HS-USB Loader. Suspecting the worst, I prepared a microSD with the debrick image on it. And sure enough, on the first try, the phone fires up into Odin mode. Interestingly, the bootloader is locked and Knox is not triggered. Which to me indicates that noone ever even attempted flashing a custom ROM, right?
Once in Odin mode, I tried flashing the stock ROM - it fails on the first step and the phone shows the dreaded "eMMC write fail: aboot". So I guess it encountered the well-known eMMC problem?
Since the seller refuses to take the phone back (despite the wrong description), I took on getting it to work myself. Sure enough, after a night in the freezer I could flash and boot a stock ROM before it stopped working. Another freeze to set it up, and a third one to install a wakelock app and set up a partial wakelock. That uses ~5% battery per hour, but the phone is still running after nearly a day.
Does that still fit to the eMMC issue? And since I have a T-962 IR reflow oven - do you think there is a chance to successfully reflow the board so that the phone can operate normally again?
Thanks a lot!

Yeah, from eBay, But I can't open a claim since it only allowed payment with wire transfer so there's no buyer's protection. The seller also keeps being unreasonable, claims I don't know what I'm doing and broke it myself, after he sold it as "he doesn't know anything about it and can't flash a new ROM". I gave him negative feedback (and had his revenge feedback deleted by eBay) but that's all they can do for me.
