[Q] PLEASE Help my device! - Galaxy S 4 Q&A, Help & Troubleshooting

My Samsung galaxy S4 since update to Android 4.4.2 .The Device become very slowly and lagly . I have already tried many ways,but They do not work.
So Must I got root? I do not want to root,because I am afraid after the root device will cause instability and cannot update the newest system(such as android 5.0). Please give me some great advice!

Buy nexus 5

What are the many ways you tried?

Do a factory reset.
This should delete all the unnecessary data that's accumulated over time.
Note: A factory reset will also delete everything on the Internal Storage. So make sure you backup everything you need!
Rooting the phone will not (usually) cause instability.
Changing to a custom rom is also an option. That will surely speed things up.
You will still be able to update to the official lollipop rom using Odin.

Nope. But Samsung seems to be slow with those updates anyway. A faster way would be to flash the update from sammobile with Odin.

Galaxy note crash!!

hello guys, i am very upset and frustrated.... My Galaxy note auto upgraded to ics 4.0.3 a few days ago. though it had become a bit slow, i mean applications would take a bit longer time to open and sometime force stopped. still it was great... and yesterday i.e, 24/06/20012 my Note downloaded a auto update... after that prompted me to restart... when i did.. it restarted and went to update mode ( where you see the green android )..... after that it rebooted and where Samsung logo appears.... it is stuck there....in few minutes my Phone heats up a lot and Battery gets drained! i tried to hard reset it but with no luck....
please help if anybody has some solution... thanks
Can u use recovery to wide data cache or maybe download latest stock rom then use Odin to put back to factory if u need help let me know
Sent from my GT-N7000 using xda premium
What ics do you want to install? Lpy (europe), lp9(asian)or lp8and lpa(india).:silly:
You need new installation.
Was it rooted? or was it stock without any mods? If its later take it back to uncle Sammy and get it fixed.
Alternatively install a safe kernal via Odin-- i recommend Speedmod k3-3 and then only wipe data/factory reset via recovery.
Then try flashing the Stock Rom you want via Odin. If that doesnt work, you can explore the other options. ATM it is a soft brick, may or may not be the emmc bug..

I give you a warning first. If your not rooted there is a slim chance of getting a superbrick bug( by doing a factory reset or recovery data wipe) as samsung devs says. But if you root your phone that chances is big really big. But there is a solution, after your new ics installation flash safe kernel called speedmod k3-3. http://forum.xda-developers.com/showthread.php?t=1673072. It will not trigger the superbrick bug when doing a FACTORY RESET OR RECOVERY DATA WIPE, thats why its called a safe kernel. Use MOBILEODIN(get it from the google market) to flash a new rom, you root your phone first to be able to use mobileodin. After that flash speedmod k3-3 custom kernel to be safe.
For rooting ics rom. http://forum.xda-developers.com/showthread.php?t=1647148
On how to use MOBILEODIN. See youtube type mobileodin its a visual teaching much better for understanding

Can't flash a stock rom..?

My device:
SPH-L720
Android 4.4.2
Baseband L720VPUFNAE
Kernel Version [email protected] #2 Mon Feb 24 14:19:28 EST 2014
Carbon Version: CARBON-KK-SHINYSIDE-EDITION-20140224-140

I have formatted my phone completely. There was no rom on it, nothing installed on the SD card. Formatted the system, data, cache, preload, etc. I installed the stock firmware NAE with odin, and it went fine. I booted the device, and it boots into a encrypted screen. When I try to press enter, it says failed. When I type in a previous password of mine, it fails. I shut down the phone, boot into download mode. I install root with CF-root via odin, and flash the NAE modem. I shut down the phone, and put it back into download mode. I install philz-touch recovery, and i install a stock, rooted Deodexed rom. It installs, and reboots. Once it boots, i get an ecnrypted screen.
If i install a different rom, anything Cyanogenbased (hellkat, cyanogen, carbon) then I do not have this problem. Does anyone know what's going on? I have formatted my phone 4 times now. The device was once encrypted, but I have removed that several roms ago.
Can someone tell me what's going on?
edit/
I'm seeing stuff about knox security. Is this what i'm seeing?
edit-fixed!
Alright, thanks to a user suggestion in this thread this is what I have done.
1) Install Unofficial Carbon and complete the initial setup.
2) Encrypt the device. Your phone must be plugged in, and at least 80% battery.
3) Then rebooted into Philz Touch recovery, and cleaned to install a new rom.
4) Installed 4.3 stock(ish) rom
5) I was then able to boot, and the device did not ask for an encryption password.
The only conclusion I can come up with is that since I re-encrypted the data, that it deleted it and the old partition when I cleared my system/data. I have no idea to be honest, but now the phone works.
I was not able to get any stock rooted firmware other than Stock(ish) to work with the modem. I flashed it, I used CDMA to write the PRL..but nothing. I may try to do that later, but for now i'm on an essentially stock 4.4 ROM with an NAE modem.
Sorry, but if your phone was encrypted before, you may be out of luck with out a password. If it was as easy as a factory reset to defeat encryption than your data would never be safe. You may need to take it into Sprint and see if the tool they use to force a firmware install can fix it. Also, if you have an sdcard installed remove it and try to odin the stock tar again and boot up. It may just be that your sdcard has been encrypted and without it in your phone it will work.

The Sdcard isn't in when I am experiencing the problem. The encryption before shouldn't matter, as it's been formatted and i've installed countless roms since.
Looking for a better answer
Nobody has had this issue or knows someone that has? A google search hasn't returned anything useful other than what i've already done.
Encryption has nothing to do with SD cards. You can encrypt your phone data. And without that password, no amount of flashing with get you back in.
Sounds like you need a visit to a Sprint store to help. They have tools that can get you back in to your phone.

I don't see how me encrptying the device won't bring the storage area back. If i format an encrypted flash drive, i get all of my storage back?
I visited the spring store today, and they told me they couldn't help me..so i'm here again.
could it be possible that re-encrypting while your runnin on cyanogenmod rom would either over-ride or over write the previous encryption? (i have little knowledge of encryption, but just a thought)

I think the issue is, once you encryrpt your device, its encrypted. Have you tried to ODIN back to stock firmware. You would probably lose your data, but you would get your phone back.
That's a guess. But this highlights a reason why encypting devices can be bad.

I have already flashed it to a 4.4.2 firmware. The problem only exists with stock firmware and stock rooted ROMs, not custom ROMs like CyanogenMod.
An update..
So I encrypted my device using the Carbon-rom, and rebooted into recovery. I wiped my device, and installed the Stock(ish) ROM. I was able to boot into the device, without any kind of encryption screen.
I am going to try a fully stock rooted 4.4.2 app and update this post.

Definitely let us know how this plays out.
Like the other guy said though this certainly highlights the reason a lot of people are scared to encrypt. their phones. I hope you get it going again!

I was able to encrypt my phone while running carbon. Upon completion, I rebooted into recovery and wiped to install a new ROM. I installed the stock(ish) ROM running 4.3. I then updated my profile and the device activated. Everything works as it should.
I tried installing a stock rooted NAE ROM and it installed fine. The handset was taking ages to update though. I flashed the NAE modem, but that doesn't work either. All in all I'm still happy.

I have updated the original post with more information about what I did. If anyone faces this problem, let me know and I will try to help you the best I can.

Need FULL WIPE

Hi. I have the Galaxy S5. I updated it to the latest firmware which screwed my device. It is overheating for nothing. Many time I flashed back to stock roms but nothing's changed. I suspect there is still left in the device from the latest firmware "virus". I want to do full wipe. I heard wipe cache and wipe partition only delete user's data. Isn't there a way to start from FULL scratch? Thanks.

If you reflash your device and you do a full wipe from recovery, then your phones software should be like brand new. It might be a hardware issue.

No it doesn't delete everything. Because when I downgrade to KitKat from Lollipop, the power off battery animation is still from Lollipop, just for an example. That's why there is TWRP recovery (just discovered it) which allow you to delete the Data, Cache, System and Preload partitions of your internal memory. Since I am not rooted "yet", I am looking for an alternative for it. Anyone?

When you flash a full firmware from sammobile it should reflash everything, including custom recovery or the boot animation.

MAYBE it should but it doesn't in my case. I'm telling you the device has Lollipop power off battery animation while KitKat firmware is installed. There are still something left in the device. Look for the thread below:

Why should TWRP or CMW recovery separately add System and Preload partitions options if not for a reason?
I think I have to root and lose my warranty. Damn you Samsung...
Because no OEM in their right mind is going to give people a device with a recovery capable of wiping the system partition, that's completely inane.

Yeah? What makes you think it is completely insane or insecure to do this? Are you saying TWRP developers (and others who put that choice to their recoveries) are stupid? Do you think they put that option just for hobby?
Jesus Christ, I'm saying giving that option to the average customer is stupid because they would delete their system partition, brick their phones and then blame the makers of the phone. Why do you think you break your warranty when you root or install custom software like TWRP?

Here is what I do so far:
Revert back to factory settings
Delete old app infos via Google
Wipe cache and full wipe via stock recovery
Flash full ROM via Odin
Root and custom recovery to wipe system, cache, dalvik, boot, simply anything can be erased
Yet nothing helped. Using KitKat 4.4.2 now and still have Lollipop animations that indicates there are datas AFTER all of those wipes. I'm absolutely furious!!!
Will my device be okay if I flash another country's stock ROM?
I can't understand this situation really: Why even after all those wipes I still end up with the Lollipop battery animation while I'm using KitKat (even very early builds)? Let me be clear: I am no against the Lollipop battery animation but it confirms some data are erase proof. And because of it, I think there is no way to get back the phone to its very roots. Is there a logical explanation for this or shall I stop trying by calling it Android's stupidity?

I did try to install it, the file downloaded and phone rebooted... then Prince's recovery screen loaded up, forgot I rooted the phone the other day using his excellent "Lenovo K3 Note Manager" tool
I might unroot my phone another day and try to install it again. The only thing bugging me about the marshmallow update is a problem I'm having with bluetooth streaming, songs aren't resuming when I disconnect/reconnect they restart. I doubt this update will fix it anyway, from what I've read it might have to wait until 6.0.1 is released..

I used version 3 to root the phone, but I haven't tried unrooting it yet.
After update the wifi is very stable and i am getting the full bandwidth that my ISP provide.
Any way this update can be packaged as an update.zip ??
My phone is rooted and on TWRP (s422 clean rom)... I would rather not unroot, and redo the stock recovery, just for this update, but I am getting data connection drops after power cycling.

Did you lose the root access after updating or was it still there? AFAIK this update shouldn't do anything to root, but you can never tell

How much free space of the internal storage you have? It's recommended to keep at least 20% free, if you have less your phone can start to slowdown

That's strange, if it isn't after factory reset (without any apps installed) smooth, then try to download the stock firmware, put it on sdcard and reflash it with holding all 3 buttons when you're powering on your phone. Or you can try to disable some google services, that you don't use (like google play music, google now, google + etc...)

Well i disabled tons of apps like i always do when i pick a new android phone. Is there a dif between reflashing the stock firmware and wiping cache/dalvik cache? Also i dont have an sdcard available right now.
Flash CM13, a lot faster
If thats the only thing I can do, I will. But I dont like alpha builds, too much inconsistency for my taste..
If you have root access try the app L Speed, there is also the trimming feature
I'll root it as soon as i can, the website for unlocking the bootloader just doesnt work..
The english site usually don't work, I used the chinese one
Can u leave a link please?

Try using trimmer, i ran it and my phone is much faster now.
I'm running the beanstalk as a daily ROM. I have flashed it dirty over cm13 build (configured finger id first then flashed beanstalk).
Both can be found on meticulus's website
Known bugs :
Endcall bug : displays FC message, does not affect the service.
No nfc
Finger id : fix with the dirty flash
Themes bug : fix is on the website
Its very smooth and has lots of features build in to customize and alter the phone.

Actualy i unlocked the bootloader, flashed b161, flashed twrp, flashed root. I also installed xposed and enabled its features for greenify, amplify and powernap. This SD Maid sounds just like an cache and dalvik cache wiper, but maybe i missunderstood.
Any other suggestions?
I want to install medrom until N is leaked but simo255 said its based on b201, a firmware which i couldnt find for L21, only L31 and i dont know what i can screw up by flashing it over the b161. I dont have time to unbrick my phone if somethings going wrong..
