[Galaxy Note5 Q&A, Help & Troubleshooting] danarmor:
Hello,

I am a noob... My note 5 went into boot loop several days after installing Avira (after the last update my phone said I had a virus... I should have known better)... I have spent many days researching and trying different things... most advice came from XDA so I joined. I have learned a lot but still have no success.

Samsung says I need a new phone... the local store took out the battery with no luck... They said its a gonner. Really??

I can get the phone into download and have it talk to my PC, but that is it... I cannot get into recovery or reset the phone

I was able to downgrade to OK3 using odin and passed, but still boot loop

I have purchased software to recover data, but FRP has blocked it

I have tried many different ways to remove FRP, but all have failed... I don't think I ever put this phone in debugging mode so I think that is why the other things have failed.

Is there anything I can do? Can you point me in the right direction (as long as it is not the trash can)

Please help.

Since you can get into download mode , have you tried to flash a full firmware package (make sure of model number first) via Odin ? sammobile has most firmwares. I would start with that. Good luck
[Galaxy Note5 Q&A, Help & Troubleshooting] danarmor:
Thank you so much for responding... I flashed ok3 from one of the links posted on this site using Odin and it passed successfully, but did not fix the problem. What would be the full firmware pack and were could I find so I know I have the right one
[Galaxy Note5 Q&A, Help & Troubleshooting] Rosli59564:
Just use smart switch. You don't have to worry about which firmware to be flashed. It will decide for you.

Sent from my SM-G925F
[Galaxy Note5 Q&A, Help & Troubleshooting] danarmor:
I tried that before with no success, but since Smart Switch had an update I tried it again... It says it does not support my SM-N920P.

I tried emergency rescue and it recognized my model number, but says I entered the wrong SN... I pretty sure I am entering the right SN
[Moto G 2015 Q&A, Help & Troubleshooting] acejavelin:
So after a few users have claimed that a Class 10 card is the same as a UHS1 card, and thus you really don't need a faster card like a UHS1 or UHS3 card, because they all have a minimum sustained write 10MB/s per the SD specs... I decided to do some testing and benchmarking to determine if that is the case because I was bored.

I started with A1 SD Benchmark and I also did some comparison of adopted storage vs portable storage with SD cards and found little difference in speed in the benchmarks, so I testing everything as portable storage because the point was to see if the card rating made a real difference in THIS device. I also discarded any test results that had cache hits. The Moto G 2015 used is a purely stock XT1540 2/16GB version, no apps are installed besides the benchmark app, SD Insight, and what came on the phone, and it was given a fresh reboot just before starting and allowed to sit for 10 minutes or so before starting. Each card was freshly formatted as FAT32 in my computer's card reader before being inserted into the G. Unfortunately I do not have a UHS3 card to test with.

Test Results

Internal 16GB storage: 98.60MB/s read - 42.69MB/s write

Samsung EVO+ 32GB UHS1 Card: 44.81MB/s read - 19.45MB/s write

Samsung EVO 64GB UHS1 Card: 38.44MB/s read - 19.45MB/s write

MicroCenter (generic) 16GB Class 10 Card: 21.11MB/s read - 11.22MB/s write

PNY 16GB Class 10 Card: 20.32MB/s read - 11.58MB/s write

Sandisk 6GB Class 6 Card: 20.64MB/s read - 14.18MB/s write

Toshiba 4GB Class 4 Card: 22.80MB/s - 9.68MB/s

And just for grins... My Moto X Pure edition's 32GB internal storage was able to do 101.59MB/s reads and 45.89MB/s writes, so not much different the Moto G 2015's internal storage, meaning that the eMMC chip is probably the limiting factor. SD Insight says the G3 uses Micron internal eMMC chip, and the Moto X uses a Toshiba storage chip.

So looking at the results, there is a significant difference in both read and write speed between the Class 10 and UHS1 cards. I just threw the others in there for for fun, although it was interesting to see the Class 6 Sandisk card put up impressive write speeds, although I am not sure why it was so high but subsequent tests were similar. The PNY card is the "normal" card installed in this phone, but the phone thinks it is a Lexar card and SD Insight says it is a Barun Electronics storage chip, which matches up with both PNY and Lexar. Also, every single test with the UHS1 cards yielded a 19.45MB/s write speed, so I am guessing that is the limit of the card reader chipset to be able to write data in the phone, but I can not substantiate that as of yet.

Take it how you want... I was bored, but a UHS1 card is clearly faster in this device.
[Moto G 2015 Q&A, Help & Troubleshooting] Gravemind2015:
Can the FileSystem affect read/write speeds? I am using a SanDisk 64GB Ultra UHS-1 card. While doing backup in TWRP, the write speed was 7-8 MB/sec with FAT32 and 3 MB/sec with ExFAT.

A screenshot -

Thanks.

[Moto G 2015 Q&A, Help & Troubleshooting] acejavelin:
Possibly... I will test it when I get home Thursday night, but it could have more to do with a simultaneous read/write that is occurring or something else in TWRP though.
[Moto G 2015 Q&A, Help & Troubleshooting] pjc123:
I used the same program (with the Long Test) to see what results I would get on my UHS-1 card. I chose the Sandisk Extreme when I bought the phone because I wanted to get a UHS-1 card per the recommendations, it had really good speed test results at the time on the various web SD card test sites, and the jump in price from the Ultra version wasn't too bad. Now in my case I have a lot of apps installed on the internal memory and a bunch of music on the portable storage, so it isn't an apples vs apples test compared to yours, but the results are still similar; this is probably what is hurting my internal memory write speed. I turned off WiFi and Cell service to at least cut down on traffic accessing storage. I also have a 16GB main storage Moto-G 3rd gen with external memory set up as portable storage. I ran the test twice with the same results.

EXTERNAL MEMORY CARD BRAND= SanDisk Extreme 32GB microSDHC UHS-1 Card with Adapter (SDSQXNE-032G-GN6MA). Ordered from Amazon, $17.19 back in January of 2016.

INTERNAL MEMORY = read 113.73MB/s Write 30.25 MB/s

EXTERNAL MEMORY = Read 48.04MB/s Write 24.15MB/s
[Note 7 Questions & Answers] mike208:
Note 7 is my first foray into wireless charging. I figured it would be useful at work for me as I can spend random amounts of time away from my desk throughout the day so when at my desk I can drop it on the charger and then grab it when I need to go. I just wondered if thats bad for the battery?

I already did a full drain and then full charge from there and even that I'm not sure if it's still beneficial to do. But with a non removable battery I want to make sure I'm not doing more harm than good and shortening it's life by having it on and off thw wireless charger often during the day. Thanks.
[Note 7 Questions & Answers] imatts:
Its not bad, its actually recommended. Keeping the battery as high as frequently as possible will help in the long run.

Using it while its charging isnt so good though.

From my research into battery life what you write is incorrect. There are other threads on this very subject where I precise my findings.

Ryland
[Note 7 Questions & Answers] hackdrag0n:
Apparently keeping the battery between 50-80% is the ideal scenario. It's probably ok to change to 100 but leaving it on the charger once it's fully juiced makes the battery heat up too much which is bad for it.
[Note 7 Questions & Answers] stas333:
There has been research that suggests it is better to charge the battery from around 40%-to about 95%, never full.
[Note 7 Questions & Answers] mike208:
I looked at some of the research people have mentioned and it does seem that between 40 and 80% is the sweet spot on the Lithium Ion batteries. It says not to charge to 100%, but that the phone is smart enough to stop charging ones full to prevent overheating. But regardless I suppose leaving it plugged in overnight isn't the best idea.

But in my case it sounds like multiple charges throughout the day isn't bad on the battery as long as it keeps it in the 40-80% range? I can manage that, just wanted to make sure multiple small(5-10%) charges throughout the day wasn't also shortening its life span.
[Note 7 Questions & Answers] Corbitt74:
Hard to say I guess. I was the drain and fully charge guy. Never any issues. My wife is the opposite, she should constantly top it off or close and her battery would drain faster than mine. Eventually hers would die very early. So who knows.

Always been like this with all our phones
[Note 7 Questions & Answers] Belimawr:
I know some firms in the past have built in charge counters in batteries so you could only charge the X amount of times, but that was a fair few years ago and things have moved on since.

but my phones I have charged them multiple times a day and my Xperia Z1 that I got on launch day is still in use by a friend and still has near perfect battery life despite being charged some time multiple times a day and always being left on charge overnight every night. (so thats for about 3 years now?)

my S6 I have ran on the wireless charger since I got the phone on release day, every time I went in the room I chucked it on the pad to keep it charged up, the phone still works and charges flawlessly, the Samsung charging pad unfortunately wasn't as up to the job as the phone was and died last week. but no big loss as I want a fast charging one after I get my note tomorrow.
[Note 7 Questions & Answers] dermotti:
-The less you recharge your phone, the better

-Keeping your phone between 40-80% is the best theoretical solution for best health. But if you are running your battery down to 40%, and charging back up to 80% twice a day, that's still more wear than just leaving your phone at your desk plugged in at 100%.

Or say you keep it at your desk and you have to move around office 4 times that day. So every time you leave your desk and come back, you charge it back from 90% to 100%. 4 x 10% - 40% is still less wear then the guy doing the 40-80% x 2 a day. Less charging overall.

According to Samsung.
[Note 7 Questions & Answers] Nitemare3219:
Wrong. Going above 80% is a "high stress" situation for lithium batteries. It isn't bad, but the best charging practice for absolute longevity is keeping it between 20%-80%.

Leaving it on the charger doesn't heat up the battery. It just keeps the battery in that high stress state, and isn't good long-term. If you are doing intense activities with it plugged in, then yes that is a combo for high heat which is bad for the battery.

Not really. Leaving it at 100% all day is not the best idea. It'd be better to let it run down to 20% and recharge to 80%. Unless Samsung routes power directly to the motherboard when plugged in, instead of passing it THROUGH the battery first, it is absolutely better to not keep the phone at 100% and charging while using it, heating it up further, and it is still cycling the power/wear through the cells.

Does any of this matter? No. Unless you keep your phone for 2+ years, you aren't going to notice any difference. Charge it whenever and however you want. The battery isn't going to **** out on you because of how you charge it.
[Note 7 Questions & Answers] hackdrag0n:
Thought the manufacturer warranty was two years anyway? Android phones are only guaranteed updates every two years so may as well upgrade every two years. If the battery craps out inside that time just warranty it. It's extremely unlikely though.
[Note 7 Questions & Answers] THS1989:
TOO MANY MISCONCEPTIONS. Let me clear them up !!!!

1) Lithium batteries like to sit around 50% for prolonged periods.

2) It will NOT hurt to keep your phone on the charger. The charging circuitry cuts off power once the Cell hits 4.35 - 4.4v

3) It will HURT THE BATTERY MORE to keep using it when it is depleted or near depleted. Lithium batteries DO NOT like to go below a certain voltage depending on specific chemistry formulation.

To expand on this. It is BETTER to keep the phone at 95% than it is to keep it at 5%. I personally would NOT want my battery falling low enough that it gives a low battery indication (usually around 15%)

4) High Charge and Discharge LOWERS battery longevity. Lithium batteries prefer to be charged slowly and discharged slowly.

You guessed it. AVOID high charge scenarios such as Fast Charge. AVOID fast discharge scenarios such as gaming with high brightness etc.

5) Lithium batteries do NOT like heat. Again, this is usually caused due to high charge or discharge scenarios.

It also ties in with Fast charge, wireless charge and especially wireless fast charge. Wireless charging is not efficient and energy as wasted as heat.

Personally I disable fast charge and do not use wireless charging. Good old USB Type C already charges quickly enough for me.

I might put this in a new thread.
[Note 7 Questions & Answers] Spike96:
So basically what you are saying is you the more you use your phone, the more wear you will put on your battery.

100% to 0% drain (100% total) is still more wear on the battery than 80% to 40% 2x per day (80% total)?
[Note 7 Questions & Answers] sebastianraven:

Nitemare, you are right. Almost no one is keeping their phone here for 2 years.

Hey everyone... All we needed to do was a search: Here is the quick guide to these batteries. http://xdaforums.com/showthread.php?p=3846897#post3846897

There's a more in-depth article here. http://xdaforums.com/showthread.php?t=518861

Just an FYI. These articles are for 2009 but still hold true. battery tech may have gotten a bit better, but the same rules. Both posts have cited sites as well.
[Note 7 Questions & Answers] dermotti:
Basically yes...batteries have a finite amount of charge cycles.

Charging 2000mah into your battery, whether its all at once, or 500mah x 4, should be roughly the same amount of wear on the battery.

For me, only things i ever worry about is deep discharges and heat. Heat is the worst enemy imho.

Everything else is pretty minor when it comes to wear.

Pretty much covered it here. Good post.

And avoid high heat scenarios as much as you can.

Somewhere in the samsung+ app for note 7, it says always keep the battery between 50 -90 for longevity.
[Note 7 Questions & Answers] Dodge DeBoulet:
My last phone, an HTC One M8, spent every single night on the charger for the last 2 1/2 years. I would also connect it to a charger in the car when I was driving for any length of time, and that was fairly often as I was traveling regularly. The battery life was not appreciably shorter when I retired it last week than when I first got it.

[Note 7 Questions & Answers] Nitemare3219:
4.35-4.4V? You just discredited everything you said. 4.2V is the typical fully charged voltage for a lithium battery.

You don't need to avoid **** unless you keep this phone forever. You're just hindering your user experience. Don't put it in a new thread, because we don't need this crap spread.
[Note 7 Questions & Answers] krabman:
I'm an engineer but people prefer links so rather than do a lot of typing I'm including one that offers a decent overview of lithium ion batteries and the fundamentals of their very specific charging... http://www.digikey.com/en/articles/techzone/2012/sep/a-designers-guide-to-lithium-battery-charging

I would also recommend perusing some of the literature on how quick charging works, it is a tightly controlled process that requires embedded circuitry on both ends along with its associated logic. It may be you walk away from your reading having lost your concerns about it.
[Note 7 Questions & Answers] THS1989:
And you just made yourself look like a fool.

1) Note 7 uses a high voltage Lipo battery. Nominal voltage is 3.85 instead of 3.7v. Full voltage is around 4.4v instead of 4.2c

https://d3nevzfk7ii3be.cloudfront.net/igi/3AuffXsIkk4aUsLK.huge

These are often called Li-HV in the RC hobby world.

2) I am NOT hindering my user experience.... I disable stuff I don't use because I don't use it..... With power saver I have zero slowdown thanks to Nova Launcher + Google Keyboard. I even used EZ Disabled just today and it works flawlessly and my note 7 feels butter smooth.

3) I DO plan on keeping this phone forever as with all my other phones because they get handed down to family members who are not tech savvy.

The "crap" in my post is about all the tips I can think of to prolong battery longevity. Don't like it ? Don't use the tips. Go educate yourself before spewing nonsense and false accusations.
[Note 7 Questions & Answers] belveder69:
I have since the old brick phone days always let mine get down to 15 - 20% then charge till above 90%. Once around about a month I let the phone drain all the way and charge all the way. Never had battery issues or had to replace one. My other half gets a new phone leaves it on charge overnight and uses it. She ends up with battery problems and even replacing them.
[Note 7 Questions & Answers] Belimawr:
Samsung a while back actually said with their tablets you should never run them to 0% as if they got that touch too far they would never charge again, so really you should avoid going to 0% as every time you do you are taking a gamble on if the phone will actually see the battery as viable to charge as if the voltage drops just slightly too far it recognises the battery as damaged.
[Note 7 Questions & Answers] ReformedAppleFan:
I guess like most people leave my phone on charge overnight. Is there any way to have it automatically switch off once the battery reaches 90%?
[Note 7 Questions & Answers] Ryland Johnson:
Unplug it. Failing that buy one of those plug in timers and set the time to charge accordingly.

Ryland
[Note 7 Questions & Answers] ReformedAppleFan:
Unplugging it while I'm asleep isn't going to fly but yeah - a plug in timer might work.

Was hoping for a software solution but can't find anything sufficiently automated.
[Note 7 Questions & Answers] mansi:
batteries got a mechanism to stop charging current when the internal cell of the battery is at its max voltage (as explained by THS1989), so keeping the device plugged to the charger has no effect on the battery directly, in the other hand the device is consuming some power to stay connected to the network, also if WI FI, NFC is enabled, so battery voltage will slightly drop, and since it is connected to the charger, it will keep compensating this drop by charging, even if it is showing 100% on the screen, so actually what Nitemare3219 said about high stress is also correct.

SAMSUNG's embedded battery models also register how many cycles you are a=charging the battery, and that affect life span of the battery, so less cycles mean longer life span, that can be achieved by keeping charging percentage between 20-80%.

fast charging and wireless charging is also not so good for the battery, and could cause a shorter lifetime.

best thing is to be moderate in charging/ discharging the battery don't be aggressive in power consumption (gaming with high brightness as THS1989 mentioned), also using regular chargers could expand the lifetime of your battery and lower heat dissipation from the device which might cause serious issues on the long term.
[Note 7 Questions & Answers] krabman:
Gents... When you see 100% that is not at full charge and when your phone shuts down on low battery it is not depleted. In the case of 100% that is maximum OPTIMAL charge and depleted is MINIMUM allowed charge. Where that occurs is controlled in the kernal specifically with goal of reducing capacity loss. Nor does the battery charge continuously overnight. The battery voltage must drop enough to reach a set point before it begins a tendering charge which occurs at .1 amps on QC chargers and is not counted as a charge cycle by the kernal which is also controlling that aspect of charging. Modern phones with quick charge tech use a very tightly controlled charge regimen that is quite sophisticated. Again, I highly recommend browsing the literature I suggested.

[Verizon Samsung Galaxy S7 Edge ROMs, Kernels, Reco] Dameon87:
Not possible. We have a locked bootloader that uses dm-verity. This is a secure boot technique. Changing even one byte on the /system/ partition, and flashing the default kernel, will result in dm-verity checks failing. When this happens, the phone will refuse to boot.

To take advantage of roms, you have to be rooted using the engineering kernel. Sadly, this is not something within our control right now.

Flat/Edge versions have literally no differences aside from the screen and battery. All roms apply to both Edge/Flat variants.
