[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] Pyr0x:
Phone stuck on "firmware upgrade encountered an issue screen please select recovery..

Hey guys I am in need of some urgent assistance and if anybody can help me solve this I am willing to send some funds via PayPal for the assistance.

When I turn on my phone I am prompted with this screen. It does not even boot into the Samsung splash screen and I cannot boot my phone into. The screen where you can do a factory reset.

Odin name (high speed)

Product name SM-N910t

CURRENT BINARY: CUSTOM

system Status:CUSTOM

reactivation lock : on

KNOX WARRANTY VOID:0*1 (4)

qualcom secure boot:Enable (cab)

RP SWREV:S1 T1, A1, A1, P1

secure download: enable

Then it says Phone stuck on "firmware upgrade encountered an issue screen please select recovery mode in kies and try again.

Now if I take the battery out I am still able to press the hold+power+volume down button to get my phone into download mode however I have tried to flash the firmware using Odin and the tmobile stock firmware as indicated in a thread here by our fellow xda developers but have had no luck.

I have also downloaded kies3 from the Samsung website and still no luck it doesn't even recognize my device.

I am dam near about to break out in tears because of this (lol) I know There's got to be someone an expert out here that can help me out. Sorry for the long post and I'm too sad to even come up with a catchy ending regarding a potato.

Please help !!!! :( :(

Have I bricked my note 4???
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] Misterjunky:
re: Note 4 issues

Your phone is NOT bricked, a bricked phone is dead and you would see nothing on the screen,

it would remain black and you would not see the softkey leds light up either.

Have you tried going into Recovery Mode (not download mode)?

If you can get into into Recovery Mode select "factory reset" and

then select "reboot".

It should reboot normal more or less unless you formatted /system

before this happened.

Do you have stock recovery or twrp custom recovery?

If you had twrp installed it most likely means that you were also

rooted.

That means that you can flash a zip file custom rom if you have

one in your internal or external sdcard.

If you don't have a a zip file rom in internal or external sdcard then you will need to remove the

external sdcard and plug it into an adaptor which plugs into the computer so you can then copy

a zip file rom onto your external sdcard and replace it in your phone so you can flash the rom..

If you cannot boot into recovery then try removing the battery, wait 10 seconds and replace the

battery then hold down the home/power/volumeUP buttons all at the same time until you see tiny

blue text on the top left side of the screen.

Right before you see the blue writing you should also feel a little vibration from the phone.

If you can flash a zip file rom in twrp custom recovey make sure that you do a full and complete wipe including system, data,

cache, dalvik cache and last but not least do a factory reset before flashing or if you prefer restoring a nandroid backup..

If worst comes to worst and you don't have twrp recovery then you need to Odin flash twrp (the TAR version) before doing anything else.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] Pyr0x:
Thanks for your response!

I have tried that however whenever I turn on my my phone it takes me to the screen that I mentioned above automatically. I will try to enter recovery mode using Android SDK / ADB on Windows.

Forgive my ignorance but I don't believe I had any recovery installed which I now realize was HUGE Mistake, However I do know that my phone was rooted since I rooted it myself.

I am curious about "If worst comes to worst and you don't have twrp recovery then you need to Odin flash twrp (the TAR version) before doing anything else."

I feel like that is part of the steps I need to take to resolve this issue. Any tutorial links on this would be greatly appreciated.!

Thank you so much although I messed this up I am somewhat tech Savvy and it feels great to have support from other like minded individuals =)

im in the same boat as you...have you figured anything out yet?
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] Pyr0x:
By any chance do you have Reactivation Lock: on?

If so that could be the cause of our issues.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] thefanum:
I got stuck at this on my Note 3 once (with twrp custom recovery installed), turned out I had to flash the stock recovery before Odin restoring. Never figured out why it worked when download mode/Odin had not. Worth trying if you're completely out of ideas.
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] Pyr0x:
I will give this a try do you happen to have some kind of tutorial link on where to get this done?
[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] Pyr0x:
I found the solution!!!!!!

OK GUYS I AM EXCITED TO SHARE MY SOLUTION WITH YOU ALL!!

What I did is flash twrp recovery with ODIN but it didnt work... it kept saying Get PIT Partition in the ODIN LOG.

So I tried flashing twrp recovery once again but this time I added the SM-N910T PIT Partition file I found online. But what I did is unchecked the Re-partition tab in ODIN thiss si what DID The trick!

The phone was able to go past the ODIN process and stopped on "RESET" in ODIN. So My Note 4 then Reset into Download mode and then this is where I reset ODIN flashed the Stock recovery for T-Mobile Note 4.

It took about 3 to 5 minutes to complete and I finally got that sweet SUCCESS on ODIn.

My phone then restarted and Voila! I have my note 4 in working condition once again!

THANKS EVERYONE FOR YOUR HELP AND I HOPE THIS HELPS YOU OUT AS WELL.

Hi everyone, I've recently finished to read a very thorough book about java programming and now I'd like to put into practise what I've learned. I'd like to start developing android apps, but, even though I searched a lot through internet to find something that could help me with this, I didn't find much. So I'm asking you, what should I do to learn how to develop android app and how should I begin?

[Android Q&A, Help & Troubleshooting] Seeros:
Ok but I don't think that is what I need. I think a book or a tutorial could help me because I know almost nothing about android developing: I just know a few things about activities, that's all; but if I had to make an actual app, I wouldn't know where to start.

So, my Micflip just arrived today and it works pretty good with the Nexus 6. I ordered the 100cm one.

the micro-USB connector is super nice and doesn't sway while it is connected. Turbo Charging is working like the stock USB cable and it also syncs well like a normal USB cable should. the braided finish gives this "tough" look.

great product in overall!
[Nexus 6 Accessories] JTheAppMerchant:
I thought the crowdfund campaign was still running, how did you get yours so early?
[Nexus 6 Accessories] nigelorion:
i might need one of these. i swear it took me 5 minutes to plug my n6 in the other night lol
[Nexus 6 Accessories] mflow:
i was on their early bird package. they are still running their campaign because they announced shorter and longer cable length. they now got the 20cm cable and 200cm cable as well. the early bird one was 100cm.

similar reason with mine back then :p . another reason is, all my USB cables has flimsy connection with my N6 USB port, it's like not fixing properly with the port. so... i gambled, and won :p
[Nexus 6 Accessories] mrro82:
You can't feel for the prongs to know which side the charger is facing? Not being an ass just curious.
[Nexus 6 Accessories] PaisanNYC:
You mean those two little nubs on the metal plug that gets inserted in the phone? Then no, I have manly hands, not little girly hands.
[Nexus 6 Accessories] mrro82:
Neither do I. I'm a mechanic in the military and I can still feel them. Any other wise comments?
[Nexus 6 Accessories] mflow:
well, i can. but too lazy to do that. but i got other reason to buy the cable, not just because "i can't feel the prongs of my old cable then i need to buy reversible plugs, blah blah blah"

it's just curiosity of trying new things..
[Nexus 6 Accessories] mrro82:
Fair enough. Like I said, I wasn't trying to be an ass. Just curious.
[Nexus 6 Accessories] PaisanNYC:
Nothing against you, and thank you for your service.

But military mechanics can also have dainty hands ;) easier to reach in tight spots (thats what she said)
[Nexus 6 Accessories] mrro82:
Thank you. And yea. Some mechanics do. Someone's gotta get their hands in those crevices. Lol.
[Nexus 6 Accessories] Pilz:
From what I've seen that's correct lol. The mechanics or UT guys always had dainty hands to fix those generators and 7-tons that never worked.
[Nexus 6 Accessories] DogzOfWar:
Besides the cost being high (compared to the 10 cables I bought from Monoprice), you haven't noticed any downsides to these cables? Can you flip either side at any time? This seems like black magic to me.
[Nexus 6 Accessories] mattprice86:
I pledged a couple months ago and am still waiting for my 200cm cable to come in. They just sent an email on Monday stating they have all the other parts to start making the longer cables, so hopefully they will be made and shipped out soon.

I also pledged on the znaps as well and am very pumped when they finally start shipping those.

---------- Post added at 03:42 PM ---------- Previous post was at 03:41 PM ----------

Did they send you a tracking number, or did it just show up?
[Nexus 6 Accessories] asrr62:
cool idea but we dont know the gauge. i got a portapow 20 gauge cable its great with the turbo charging.
[Nexus 6 Accessories] Mr. Orange 645:
I also pledged for the Znaps. I think I've ordered two or three of the Znaps and like sixnof the cable adaptors. With some discounts they offered, I got all of that for like $30USD. Now I'm considering this flip cable.
[Nexus 6 Accessories] mattprice86:
Yea I ordered about the same. I was pretty surprised at how cheap they were for the backers. Hopefully they ship soon. I want to test out the micflip tho as well. That'll probably come in first
[Nexus 6 Accessories] mflow:
the flip-able side is the microUSB side, at the beginning, they were designing it to be fully reversible (including the male USB connector), but they hit some problem, and finally only the microUSB is the reversible one.

my friend ordered the Znaps, and i went for the micflips :P

==

it just shows up in my mailbox here, no tracking numbers, just suddenly shows up.

ps . I'm in Australia, US backer might get it quicker.
[Nexus 6 Accessories] KILLplay:
There are a couple of these reversible micro-usb cables out there now. I just ordered my N6, and I want to order one of these cables, but are they fast-charging compatible?

I read the N6 is supposed to be quick-charge/fast-charge compatible.
[Nexus 6 Accessories] Gungrave223:
You should not that the cable doesnt determine if your phone can be fast charged, but rather the power source (the adapter the cable plugs into)
[Nexus 6 Accessories] mrro82:
Just ordered mine. 100cm and 200cm for $30. Good deal to me.
[Nexus 6 Accessories] mrro82:
My payment cleared through PayPal this morning. I haven't received a shipping email. Does this mean they are on the way?
[Nexus 6 Accessories] mrro82:
Guess they had some defects to sort out. Should be shipping soon for me.
[Nexus 6 Accessories] mrro82:
Edit: NM. User error. It's working now.

[Samsung Galaxy Core.] stefguer:
[MENTION=5469444]Agasharr[/MENTION] I agree with you, I ignore which is the best for us. By the way, this list may be outdated since 2012, maybe some new governors exist now ?

Hi, You want to flash kernel?

If so download G386FXXUAOA1_G386FPRTAOD1_PRT 3.zip

[Samsung Galaxy Core.] AmineI:
Nice ! Well, i think i won't try your kernel since my battery is not really in a good state and overclocking would make it worst, but do you think you could add OTG support in the kernel ? It seems the material and rom are OTG ready ('drivers' etc) but the kernel isn't
[Samsung Galaxy Core.] Agasharr:
There are some otg settings in kernel config:

CONFIG_USB_OTG=n

CONFIG_USB_OTG_UTILS=n

CONFIG_EOS2_USB2_OTG=n

CONFIG_USB=n

CONFIG_USB_DEBUG=n

CONFIG_USB_ANNOUNCE_NEW_DEVICES=n

CONFIG_USB_DEVICEFS=n

CONFIG_USB_DEVICE_CLASS=n

CONFIG_USB_SUSPEND=n

CONFIG_USB_R8A66597_HCD=n

CONFIG_USB_OTG_WHITELIST=n

But even when compiling kernel with all of them enabled (except CONFIG_USB_OTG_WHITELIST) OTG doesn't work. So it wont be that easy ;)

As for battery life, it almost the same when idle as on stock, base clock is almost the same, differs only few MHz from stock. It uses more when You need it and that is obvious as it's overclocked over 400MHz from base clock.
[Samsung Galaxy Core.] Agasharr:
OTG no go ;)

OTG seems to be unavailable in G386F, even with kernel support it can't detect any connected device, and even more it's getting problems to connects the usual way to computer as a usb device. Or simply I did something wrong.
[Samsung Galaxy Core.] Agasharr:
Update: 25.01.2016, details at the first post.

If You want to reduce cpu speed, You can use an app or an init.d script, example:

#!/system/bin/sh
if [ -e /data/local/cpu_protection ] ; then
echo failed > /data/local/cpu_failed
chmod 777 /data/local/cpu_failed
exit
fi

echo applied > /data/local/cpu_protection
chmod 777 /data/local/cpu_protection
chmod 666 /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
chmod 666 /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo "1602250" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
chmod 666 /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo "201500" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

chmod 666 /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo "ondemand" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
chmod 666 /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
echo "1602250" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
chmod 666 /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq
echo "201500" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq

This script can change cpu governor, min and max cpu speed.

You just need to edit it to suit to your needs.

[Samsung Galaxy Core.] miki4:
Hi Agasharr, how do you compile the kernel? Where do you get the sources from?

I would like to have your proven modifications also in the kernel of the latest firmware (G386FXWUAOL1_G386FPHNAOL1_G386FXXUANL1_HOME.tar.md5).

I compared the boot.img of this firmware with the boot.img of G386FXXUAOA1_G386FPRTAOD1_G386FXXUANL1_HOME.tar (which I guess is the firmware your modded kernel is based on) and they are different. I could imagine that the new boot.img is further optimized so it would be worth it to build a new modded kernel and that there could be problems using your current modded kernel with a newer firmware.

In the attachment you find those two original boot.imgs. If you have time and are in the mood for this, I would be very happy to see a new modded kernel. :)

Thank you in advance

hi all, I have a little question on s4 mini duos I9192.

using "free" or "meminfo" commands displays memory informations, the phisical ram displayed is 1,3 gb but the phone is declared 1,5 gb (:confused:) , so I thought it will be some zram but analising the memory its not zram.

by the way there is a swapfile of 1gb.

please can someone confirm this? I am playing with swappiness value and I must be sure if I touch zram or swapfile

screenshot attached
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] RuffBuster:
I'm guessing your using stock os as that uses a 1gb swap file. Zram is kernel dependant and I don't think stock makes use of this. Although our phones have 1.5gb RAM some of this is stolen by Android OS. The same with our 8gb storage which part of is stolen by Android again leaving us with around 5.5gb.

Would like to know how you get on with different swapiness values, and which you decided to settle on.
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] holymoz:
Thanks, yes I'm on stock.

I noticed that the 1gb swapfile is little used; with swappiness 100 swapfile is used about 200mb and with swpss 20 about 40mb both after 1 day of use;

Also the used part tends to accumulate and grow from boot but I shutoff phone at night so swapfile resets at boot.

My idea was to delete swapfile to recovery space bit I can't, swapoff doesn't work.

Anyway I think phone is smoother with low swappiness and with medium usage I never suffered lack of ram problems.
