hi everybody.
I have a samsung galaxy s4 gt-i9505 which is rooted running echo rom 4.3 and all of a sudden my phone has started to reboot itself constantly..(rebooted about a dozen times already today and ive only been awake about 2 hours!!)
What i was wondering is...
Can i go back to my 4.2.2 backup i made in recovery and then flash the official 4.3 update with odin (i know this will trigger knox but i need my phone to work)
If there are any other suggestions anyone has which will not trigger knox it would be greatly appreciated.
many thanks.
What is your battery serial number?!
Read this thread http://forum.xda-developers.com/showthread.php?t=2488245.
A friend of mine had the same reboot problems and they changed his battery. And gave him a free new one but from the same batch with problems.... now he wants to send it back again since his reboot problems reapeard.

Maybe just start with going back to 4.2.2 and see if that fixes the problem first.
Then take it from there if u wanna choose a custom knox free rom or not
Hi,
do you have only battery drains or also random reboots?
the fact is that samsung shipped out a bad serie of batteries (which is confirmed by Samsung) their serial starts with BD
the symptoms of a bad battery are:
Huge battery drain
random reboots
while rebooting the phone hangs at samsungs logo
battery is swelling
phone shutting down while you have an incomming call/sms
when you are the "lucky one" to experience one of the above symptoms please replace your battery asap under warranty
if you don't do this you risk a phone exploding in the pocket of your pants this is not only painfull for your phone but also for "everything else" whats in there
^^^^^^^
Thanks for the info man.I'll let my wife test out my phone when I get it friday.
Hey guys i have a samsung galaxy s4 on android 4.4.2 kitkat and i am not happy at all with the kitkat update since it has ruined battery life and is causing many other problems like lag and overheating
So i want to downgrade to the stock 4.2.2. I have never rooted my samsung galaxy s4 and i am still unrooted.
I know knox will be set to 0x1 after downgrading but i do not care about it as triangle away supports galaxy s4 now .
So here is what i want to know
If i download the proper 4.2.2 firmware from sammobile according to my country(India) and install it via odin then will the process work? and if it is the right procedure does it require root ?
Is there any chance that my phone can get bricked because of knox ?
and how should i take backup of efs in case of a possible imei error ?
I know how to downgrade i9505 but i9500 Im not sure about it I never tested it out
I think you can downgrade successfully, I have a thread about how to downgrade from 4.4.2 to 4.3 but its for i9505 check my profile threads
You can downgrade successfully if you follow my guide, but you will lose wifi of maybe imei
So you can solve 4.3 wifi problem by downloading 4.3 kernel
You can use the same way to downgrade from 4.3 to 4.2.2
And for how to backup your imei you will need a rooted device !!
There some apps that backsup imei
Just look for your phone model "gt-i9500"
And you can backup you system starting from imei by having custom recovery like CWM and do Nandroid
And Knox will be tripped
Downgrade or Install Custom ROM

Hey dude,
I don't really understand how the s4 lags - did u try resetting the device?
the battery life is fine with the latest update.
Overheating is still there in i9500 & also it cools down rapidly - I guess its a HW design. Hope it wont be fixed.
I was annoyed with the overheating issue & now i am used to it. It heats while using 2G or 3G Internet & playing games.
Using regular apps it doesn't heats up & now i am okay with it.
Regarding the downgrade, frimware from sammobile will work fine. You will have to install via odin.
no your phone wont get bricked cos of knox - I suggest you to follow a video tutorial and do the downgrade.
But I recommend you to try a custom rom such as Omega, Hassan etc
In my experience the these roms are very good on battery and performance. Pls do note these roms (Omega, Hassan) are based on samsung stock rom.
If you still want to downgrade, I would suggest you to take it to the service center guys & they will do it for free.
Hope this helps!! :good:
Yeah it mostly gets heated while playing games and using chrome
Though i can still live with the heat because eventually i will get used to it after some time
But the lag is killing me
My phone shows lags while entering and leaving apps and camera and gallery too and it was not lagging before on 4.2.2
Also i have experienced significant battery drag
While using the internet it falls of by 1 percent every two minutes
Is this kind of battery drop normal ?
I am really missing the old firmware so i think i am gonna go to samsung and get it downgraded from there
Thanx for the sugesstion bro

I think will be not easy. You voided ur warranty when u downgraded (KNOX:0x1). No service centers will fix it (in theory) :highfive:

Hey bro,
In my experience with the S4 on Stock ROM I never experienced a lag.
Please check on the settings - switch off the gimmicky features such as Air View, Air Gesture, S Beam, Air Gesture, Motion, Palm Motion etc etc.
Settings --> Connections Tab --> NFC, S Beam, Nearby devices, Screen Mirroring
Settings --> My Device -->(scroll down) motions & gestures, smart screen, air view
Turn locations off
Check the battery graph - see which app consumes more
I had this issues when these features were on.
The phone will be always hot, battery was draining like 1 % for 1 to 2 mins.
There is no lag with camera and gallery.
Battery drag is bit similar that I lose 1% for every 3 to 4 mins on 2/3G Internet. But on Wifi battery is solid.
In my opinion battery is very solid in S4.
The latest firmware is very stable. The performance has increased from old firmwares.
If you hv rooted the device, and got custom recovery just try a custom rom.
Okay i think it would be good to try the custom rom
So i am gonna try that and see what happens

As I know, if you download an official firmware of samsung from sammobile, you can downgrade/upgrade your firmware without rooting, just flash via odin. Maybe you can uninstall KNOX first before downgrading, open KNOX mode and press menu and click uninstall KNOX. I hope this helps. Good Luck
Hello!
Today I had a really weird situation with my Samsung Galaxy S3 Neo !
I put the phone on the charger as usual, then went to sleep.... Only to wake up on the boot intro sound of my device several times!
The only obvious reason for this situation is probably just putting my phone on the charger!
I tried to reboot several times, removed the battery and waited for a while, but in vain! Sometimes I had the logo screen, very slow one with a stuttering audio, sometimes not.
I tried to flash stock Kitkat firmware 4.4.4 (the same Hong Kong one I was using already)... No change!
I couldn't boot properly into recovery till I decided to flash TWRP and do a full erase of just about everything that could be erased!
The result?? You guessed it... NO CHANGE! Still the same bootloop, while sometimes I could see the launcher before the reboot!
I decided to try to flash the previous firmware that was before the update (4.3 Jellybean, UAE) and send it to the service center, and I just removed everything from the phone: The battery, and all the cards were removed and put aside! However, I found that this will trigger the Knox Warranty flag to 0x1, definitely not the best shape for visiting the service center! :\
After all, I decided to give it one last try to boot before I send it to be serviced just the way it became. To my surprise, I managed to boot successfully and restore almost everything. The only noticeable loss was the Samsung "Over The Horizon" soundtrack! (Got links for this one, please??)
However, all that flashing wasn't for free! I had a change of both firmware statuses to "Custom" after I had a once "Official" firmware tag! To my chances, I didn't trip the Knox Warranty Flag, and I had my device rooted using CF-AutoRoot with Odin!
A few questions here:
1. What the heck is going on?! What caused all of this from the beginning??!! The phone was rooted and working great before that! I even managed to resolve the battery drain and the camera issues for good! (I'll describe my method later )
2. After all that play, how come I didn't trip the Knox flag?! Was it just... luck???!!!!
3. Can I change to the UAE firmware from the Hong Kong one without tripping the Knox flag???!!! I have little problems with the Hong Kong one, despite the fact that I had some crashes and minimal glitches before! As you all know, Android is a glitchy OS, but this one has much less glitches than before.
Thank you for your time. Hope to see your thoughts asap
Question 1: I read similar problem on samsung phone somewhere caused by defective or dirty microUSB connector. Perhaps your several flashing resulted on dislodging of the dirt from the connector thus your reboot problem was resolved.
Question 2: I also flashed 4.3 over kitkat from hongkong rom and the knox was not tripped. Perhaps only rom 4.2 and below will trip the knox?
Question 3. I have done flashing from Hongkong to UAE to Russia no problem with knox.
Good luck!

Thanks a lot!
BTW, which one is better to use of the three firmwares you flashed already?? I have the I9300I with the 1.4 GHz Quadcore CPU and I know that some firmwares are made for the 1.2 GHz edition...

You may have read my experiences with kitkat on a separate post? I am back to 4.3 now.
Anyway the most stable among the 3 is the latest Hongkong kitkat. Some users here suggest Kazak rom but I has heating problems with that...
I am using exynos on N. Was getting ~6 hours SOT on MM, phone would last almost 2 days. After flashing nougat, only getting around 2-3 SOT and phone doesn't even last 1 day.
I am:
-not using any package disablers
-not using AOD
-I would say even usage of wifi/data
-all motion detection off, not very many apps doing background syncing (or so I think)
I have owned this phone for almost 1 year now, always fast charging everyday so my battery is probably very weak by now.
Should I:
1. Try flashing a custom debloated N ROM? (I've had people on here tell me they used ton of different N ROMs for months and they still went back to MM for longer battery life.)
2. Try flashing a custom debloated MM ROM?
3. Pay ~$70-80 to get a new battery?
For example I am considering flashing superman rom but not sure if I should flash mm or N.
I don't know how people are getting 8-9 hours SOT on nougat. If anyone could give advice that would be great.
Thank you.
Hi,
Since you're charging the phone everyday with fast charge and is using it for almost a year, then you have to keep in mind that the battery won't last as long as when you got the device.
You can however try to get around the aging of the phone by making use of less bloated ROMs and more battery efficient kernels, if you're not using Knox featured neither is using Samsung Pay, then since you're at the end of your warranty I highly recommend installing a custom ROM.
I do not think that the downgrade is a good solution, first because you won't be able to do it AFAIK, Samsung Knox prevents a system downgrade ever since the S4 IIRC. So unless you get a custom Marshmallow ROM that works for your current Nougat bootloader (which isn't impossible, I think most should run).
Personally in your situation I'd first try a clean stock install, if the problem persists I'd go for a Nougat ROM, because since you are installing a custom ROM, why not go for the latest and greatest instead of downgrading since you can get a good battery life on the Nougat ROM as well?
All the best,

I'm as well having poorer battery life on Nougat than I had with MM, though 2-3 hours SOT seems to be too low.
On Nougat I get 5 hours SOT, while on MM 7 hours were the norm. Hopefully Sammy will release some update "soon" (lol, ok: somewhen...)
Anyway, what do you mean by downgrade not possible?
What happens when I flash a stock MM Rom through ODIN now, won't that work?
Downgrading to MM from Nougat works just fine by flashing official MM Rom via Odin.
I did it on my G935F because I'm using xposed which is not yet working in Nougat.
Hi,
Good to know that downgrade is still a possibility, I've read on another thread (don't remember where or when tho) that some users reported having Odin simply failing to flash a downgrade (IIRC was S6 MM downgrade to LP). Sorry for the misinformation .
All the best,

It's really up to the phone's owner to decide. One can only suggest but everyone has its own reasons to choose either N or MM.
One thing i noticed during the downgrade, it's asking for your Google password so be sure to know it. It may also cause your phone to freeze during boot up, the solution for this is to go to Recovery and wipe data/factory reset and wipe cache. So be sure to backup first your data by using TB or synchronisation thru your Google acct or Samsung acct.
Also because S7 snd S7e have no removable batteries, be sure you know how to go to Download or Recovery mode without first turning off the phone.

Ok thanks
If doing a downgrade I would strongly recommend a factory resets as you may encounter a problem anytime since there's no downgrade migration.
Though everyone can decide by his own you should keep in mind you won't get any further security updates for Marshmallow from Samsung. In such case it may be better to go for a custom Marshmallow ROM which is still maintained (if available).
The battery management on Nougat is definitely better than on Marshmallow. You may search for the reasons of your problems...
It's not difficult to change the battery. There are some good step by step online manuals on youtube.
I am about to root my Samsung Galaxy S7 - SMG930VLUDU4CQH2 for the first time and I am gathering the files for the job. I have read every post from the thread https://forum.xda-developers.com/tm...eres-how-rooted-nougat-s7-edge-g935t-t3567502 . I have the Qualcomm heroqltetfnvzw version so I am sure that I am using the correct thread. The two questions I have are :
- just in case something goes wrong, which stock firmware would I use to get back to original state? The BQA2, BQH4, or the BQA4? , after the Nougat upgrade mine is the CQH2.
Secondly, I have also been reading on the Magisk technique to root and was wondering if anyone has possibly tried both of these out and has compared their stability and lag (or lack of lag)? I understand that that it varies from device to device, I am just talking about the technique.
I have actually read so much that I am getting myself confused on this whole process. Lol. Thank you in advance for your help and I have started following several of the members. You guys rock! :silly:
