Why Samsung Not Allowing Downgrade?

It is a well known thing now that after updating we are not able to downgrade the modem as it alters the EFS. What could be the reason Sammies have done this? any guess? imo downgrading the modem must have been causing lots of disruptions in transmissions or the new modems may have been programmed to some new international norms. What is your opinon?:

Whatever the reason it sucks!
Nothing compares to the battery life you get on the first 4.1.1 roms and modems.
I'm glad I made a backup of the efs partition so I could get back to 4.1.1, people who didn't are kind of tied to the new modems at the moment...

Have you even read through those topics? The problem lies in kernels, not modems. Don't flash new kernels and you are safe, I jump around between different roms, old and new, but always flash Perseus kernel after flashing rom and never had any problem with lost IMEI. Not once had I have to restore EFS.
Beside that, with Sudden Death Syndrome, it is quite sound policy to not allow users to flash old firmware as it could result in that bug again.

The strange thing is that this problem only affects the n7100 model none of the s3 variants and n7105 had this problem with the latter kernel/modems.

No s hit sherlock.
Whatever the reason it's not right. Some people like me dont care about the SDS and I will use the vulnerable roms/kernels anyway.

it makes me remember when i had my old nokia 5800...

To each it's own, I guess. I paid enough for my phone to not endanger it more than I have to. Personally I would sooner buy bigger battery than flash older firmware with known bug and hope for some miniscule battery saving advantage.
From Samsung perspective $ are more important and anything that lowers servicing costs is golden.
The incompatibilty may also be a side effect of other changes, fixing of bug(s) we, as community, are not even aware of or some other problem we know nothing of. There is no apparent reason for Samsung to close a path to flashing old firmwares unless they have some need to do it (maybe new spyware in new kernels?). We are an additional service cost because we flash and sometimes break our phones.
Changing kernel across many platforms suggest either fixing some bug (again), creating some new spyware or some strange change in software policy. Do you have a better idea?

You probably had a brand new battery when you where on 4.1.1 and now your battery has wear out a bit so it's not as efficient as at the begining. Thinking the battery life was better on 4.1.1 is a myth. Ask anyone who is not on XDA and use stock ROM all the time. 4.1.1 was buggy and not stable and Sammy quickly upgraded to 4.1.2. the lastest XXMDG1 is by far the most stable Rom ever released by Samsung and the battery life is superior too.
I believe they prevent downgrading because of some security patch.

about a year ago Sonyericson xperia Arc has ICS upgrade and eventually this ICS upgrade made the phone completely not functioning in the moderate use level. hardware limitations and etc....
and of course, absolute no way to downgrade unless root + flash rom
I don't really understand why either... maybe this is to force us to pay for a new phone, and abandon the most updated but not compatible nor usable old devices. Marketing strategy? :silly:

Probably to stop people being able to easily unlock their phone, especially with the the qualcomm versions there was a service menu hack that allowed it.
Same reason Sony didn't allow PSP firmware downgrades, older firmwares had exploitable holes.
There are very few hardware vendors that allow downgrades, mostly because older versions often have more bugs, so the prefer people to be on later versions. It reduces the surface area of firmwares their support staff have to troubleshoot.
If you think Samsung care that you can't downgrade, you're living in a dream world.

Evolve or die.

Rooting versus not Rooting

Hey guys, is rooting really worth it on this phone. I mean just look at all the threads of this issue and that issue after somebody roots. I mean for me the phone is awesome as it is with exception to it's poor SPARK speeds. But that can't be fixed by rooting. I have yet to see any real gain posted by anyone other than removal of Sprint bloatware which is much less than any other carrier. So really is the gain worth the hardship and potential issues this phone seems to have after rooting?
All I see is this phone has X issue and then next line is always the same I rooted or I installed Y ROM. It seems to me that Samsung has done something to make this phone unreliable/unstable once the Factory integrity has been compromised either through rooting or ROM replacement. I did root mine using CF auto root before seeing all these issue posted. I can say now after rooting that I as well am seeing little bugs with touch screen response, as well as other little bugs it did not have before rooting. So this just strengthens my hunch about Samsung somehow making this device less stable once it is compromised.
I don't think I am going to fool with it any further. I don't want to become one of the many help I rooted and my phone won't boot post popping up around here lately.

You dont have to install ROMs to better your device, you can root stock odexed and it will be fine.
It unlocks more capabilities the phone cant do when its pure stock, such as Freezing wake locking apps that drain battery, or enabling etc mods that make the device better under certain circumstances.
You will run into issues whether rooted or not.
Is it worth it? Depends on user opinions. Does it have more problems than usual, Sure from time to time.
The peoples reviews of custom roms are there for a reason. There are things that are fixable and others that cant be fixed or modified upon.
Its more about exploring the full capabilities your device can do when it is rooted.
How far this device has come is massively huge because of the help brought from the community and devs.

You will typically find best performance and reliability with stock android with very few modifications. I use to flash a lot of roms/kernels on my Epic 4G and 4G touch and wouldn't call either of them reliable. I stay with mostly stock roms with my GS4, just Knox removed and everything is real stable.

I have both rooted and unrooted, stock roms and custom roms on a few devices at home. Does JUST ROOTING cause any additional problems? No. Its essentially like installing any other apk. Where majority of the bugs and problems come in is user error and custom roms. Don't get those confused as they typically are. Most "I rooted any my phone isn't booting" posts are from people that do things improperly. Or sometimes things just don't stick and you have to try again. CF Autoroot didn't work the very first time I flashed it on my wifes device (last night) after I had used it more times than I can count on my own since 1 week after device launch. I flashed it again, worked great. She didn't like stock, so I flashed my own custom rom on her device.
Custom Roms come with their own bugs if they aren't just simply stripped stock. Want less chances of bugs? Use the completely debloated and no-knoxed ones. They just make things simple by removing both carrier bloat and added items (can also be buggy themselves). Also keep in mind that the software shipped isn't always bug free . We saw some big changes to the actual code from NIE to NK2, we aren't 100% sure why they changed things in some places but I'm not an expert there at all. Ever wonder why Tmobile or verizon may have a feature thats actually turn off or locked on our device? It could be buggy for a specific carrier and the carrier just decided they wouldn't include it for their customers.
Samsung perposely sabatoging our devices because they are rooted...... eh they did have nexus devices at one point in time. So I'm going to give them the benefit of the doubt and say this isn't the case. You may have just experienced bad results. I don't go a device without rooting, if not only to remove carrier bloat. MY last 3 devices I did not even let sprint reps boot before I took it home and rooted (literal first boot is rooted stock) I have been to the sprint techs LESS than when I had stock devices. This also allows certain users to fix their own problems themselves, and not leave device issues in the hands of carrier techs who by default will generally do a software reset and send you out the door.
Pros vs cons of rooting? Completely down to each specific user.

Yes rooting is absolutely worth it. For hotspot tethering, and Xposed. But you do need to add a fix to Xposed if you do decide to install it on this device.

If you have hotspot tethering included in your plan like I do why would you need to root to have it? Unless you are trying to get it for free?

reguardless if you pay for it or not, it limits the amount of devices you can connect/tether to. Who's to say I only want to tether 4-5 devices? What If I'm traveling and have 6 devices?
If you don't like rooting, this certainly isn't the place to try and shun it. If you are looking to be convinced to root again? Still the wrong place. You root because you want to, or you want to do something that you can't without root. Plain and simple. Rooting is essentially controlling your own device while you OWN IT. Not owning a device someone else has complete control over.

I root everything I own that can be rooted. My question has about the N4 as it seems like I said it has more issues after a root then it did before and that seems fishy. The way Sprint and Samsung are handling the poor data speeds is already a screw job when they are both aware it is a real problem. Add to that the more mods you do to the phone the more unstable it gets that just seems shady. I was not asking to root or not to root so much as I was asking is THIS device worth the trouble?

Seems you aren't running the right rom. I haven't had any major instabilities.

It's not the rooting that causes the problems, its what they do after they root.

As we all have said before, its user opinionated and what they do regarding with root in general.
I go with rooting because of extra battery saving features such as Greenify + Xposed, Underclocking GPU and CPU. To top that off, force lower dpi resolution and tablet mode on specific apps to see more on the screen. Modifying files such as build.prop and user key controls for enhanced performance, and like everyone, changing Sounds and boot anims, moving apps from user to system to help with stability etc.
If its unstable doing certain things well thats the bummer downside to the Apps or devices capabilities. But as long as you can get more out of the device ( which you can! ) with all the freedom of not being locked to user specific controls. It makes it better!
Thats how i feel.

I mean you can root the device and just install twrp and just keep it like that just until something catches your eye. I personally say if you rooted your previous devices. You should root the note 4. I am rooted and I am just plain stock cause I almost bricked my device. So I am going to wait until 5.0 gets to our phones before I flash anymore roms but until then I'm going to be completely stock.

Root your phone immediately.
Root your phone immediately. My god, what are you thinking going around unrooted?
Oh, you want details?
Open the hidden stuff if you want details.
Just kidding. I too suffered from doubts and waited several months before popping my phones warranty cherry.
Root is nice, even on the Note 4. But:
If you don't need root for anything special and you are perfectly happy with stock without root, DON'T ROOT!
If you need superuser authority (titanium backup?), if you want to disable Exchange Security so you can have work email but still use the fingerprint scanner, or you just like having better/different looks than stock in some way not achievable without root, ROOT. ​
That advice is general and applies to all phones. If you don't need/want it, why ask?
I can vouch that rooting the Note 4, installing custom Recovery and operating the custom ROMs is the similar to any other Samsung phone of recent vintage both in manner and difficultly (e.g. S3, S4, S5). (not the same though so do your research)
I have nothing against any ROM but, from personal experience, the ROMs from Pongoface and co work extremely well and look really nice. Make sure to wipe data and let them have 10 minutes or so to settle after first boot.
Those are:
[PORT] BoBCaTROM
and
[Port] Sprint Xnote (The time to settle was important on this one for me. Else, I got forced closes, not sure

Everything is stable on my phone after rooting and a LOT of Xposed mods. It just makes my phone much better.
If you have rooted all your other phones, then really why are you asking this question? You already know the benefits and risks of rooting so there is no need for us to tell you what to do.

False. False. False. What's shady is the lack of knowledge on behalf of a user which these issues are caused by. There is no "shady" business going on that would cause instability issues upon rooting your device. Instead of a carrier or Samsung playing shenanigans with it's customers by introducing bugs and instability issues if a user roots their device, it would be more logical for Sprint and Samsung to simply lock down the bootloader and take measures to prevent root in the first place... such as all the Verizon and AT&T customers who are still crying about not having root. If you want to believe otherwise that's up to you.
As already mentioned by millerboy3, rooting doesn't cause the instability issues you or anybody else might be having. The more mods you do the more unstable the rom??? That's just plain and simple ignorance my friend. Yes it could be true that a rom might be "buggy" but if a rom is well planned and time taken to ensure everything is right, then there will not be stability issues. There are roms out there with tons of mods that are 10 times more stable and faster than the stock rom. I happen to have a rom that fits that criteria along with a few other people. With that said, I do agree with you on the fact that the Note 4 is perfectly awesome straight out of the box without the need to root it. This is the first phone I've owned that I really don't feel the need to change anything because everything works great stock. There are a few mods that I find are well worth the effort and definitely worth rooting the phone for.

He said it much better than I.

i'll also throw a vote in for rooting. i've come to consider AdAway & Xposed as must-haves, which both require root.

The N4 was the first phone I considered not rooting, it was that good straight away. However, then I remembered why I rooted, besides custom ROM's, and it was 2 (now 3) main reasons.
1- AdFree: After seeing ads all over a bunch of my favorite apps, I remembered I didn't have AdFree installed, which requires root. This is my biggest quality of use reason, if you've ever went to tap something in an app only to have a ninja ad come out of nowhere right as your finger hit the screen and redirect you to a website or the app store, you know what I mean.
2- TWRP + Titanium Backup - The ability to backup ALL my apps and settings to a separate SD card was huge, plus all the other features of TB.
3 - Lastly, I found Xposed: I'd never used before, but now, I couldn't imagine not having it. It's allowed me to tweak things that irritated me, like color schemes on the contacts and dialer screens, without the worry of installing custom ROM's or RW editing mods.
Just my feedback, your requirements may differ.

Newbie, who wants to have better use of ExtsdCard
I am looking into rooting, for the first time. After an update to my, prior, S4, I couldn't edit my ebooks, about 700, delete photos, several thousand, or remove duplicates, on my extsdcard. I just got a new Note 4, and a 128G extsdcard. If there is anyway to restore my control of the sdcard that I paid for, other than rooting, please tell me. Otherwise, Android and Samsung are forcing me to root. Am I wrong??

I'm a little fuzzy on what your saying. Are you saying that you can't edit or delete the contents of your external SD card in the note 4? If so, that's not a problem root could solve, as you should have full control over everything on the external card. Rooting would allow you access to edit the main android system files on the internal storage.

P8000 unusual problem.

Hello.
11.11.2015 i recived a notification on phone that Elephone had released a new update to improve system functioning ect.
Keep in mind this is a stock p8000. nothing done with it.
I downloaded update, installed and it said phone will reboot.
After that phone is stuck in bootloader and simply wont boot.
Ive tried wiping cache and factory reset but PHONE WONT turn on.
So question is. What the hell do i do now?

There's like five threads about the same problem, so nothing really unusual about this excerpt for the lack of quality control from Elephone which apparently releases broken OTA:s and phones with old or modified base roms. ?
This thread should be merged with other ones.

Have anyone found a solution?

Manually flashed a new rom and now the phone works fine. Tho im not installing the new update again.
Have to be said that the people behind the update and responsible for keeping the phone updated and fresh should have been fired.
People without the necessary skills on this subject would have to return or get the money refunded because THE only way to fix this is flashing a new rom..

Also, most China phones don't even get updates, or even more exclusive, source code releases like this one. My guess is that there's likely only a one man show in charge of software development for this model, so give them some slack will you. [emoji1]

mine went off to after the OTA so i had to flash manually and like my friend said there trying, unlike most china phone company's so even though mine failed my father's and my friend's p8000 got there OTA np

It seems like the first 5000 batch delivered had no notification led,they seem to put in different hardware thats available.So end up with a hotch podge of slightly different devices.
So fingers crossed that a update works.Thankfully Elephone allows ,enables development.

It also looks like OTA update fails on rooted phones, which is not so different than what happens to most Android phones. When I used a Samsung phone long ago, OTA update notifications wouldn't even show up if you had rooted your phone, and on other phones I remember having a similar issue after I applied an OTA update with the phone rooted

Newbie with A70 Advice To Root or not to Root?

Hi
Ive just ordered a A70 and was wondering what should i do and not do ie update etc?
Im wondering should i root or stay stock
But i do fancy installing LineageOS but do i need to root to install
Also will rooting void my warranty?
Thanks

I would wait till the android 10 update comes out, before you root.
It comes out in april.
And yes, rooting will 100% void your warranty forever.

No, you don't need to root.
But you need to have a custom recovery installed like TWRP.
(Would not recommend tho, to install a custom rom, because of the bugs. It's pretty unstable right now.)

Ok thanks

i personally like rooting all my phones i get.
but due to the lack of many custom roms, i first just used my phone as it is - stock.. see if i liked it like that and it was actually perfectly ok.
however after a few weeks i needed some extra volume boost with Android Auto, so i rooted to solely use Viper4Android.
my advice try stock for awhile see if you like it, if tou desperately need a rooted app then root.

I got a stupid question... will rooting my a70 prevent me from updates?

If you don't know why you need to root (without reason to install LineageOS, coz without root if i'm not wrong, it will not available), better stay away from root at all. Second it void yours warranty, but this is not worst thing, if you don't have nothing common with rooting, you can easily brick yours phone. Will be problems with that, you can easily lose it. Yhea, yhea developers probably know how to fix that and my warning sounds like funny post, but when I had one this situation, I had to bring it to authorized service (Then I had warranty and I did not said true what's happen in authorized service for fact that I could lose warranty. So they thought it just stucked my smartphone on boot without reason over night). As I know they changed motherboard and how I understand they did not unbricked it with programming process. So if authorized service will detect that it's your fault (if you will have to bring to they), you have to change motherboard (probably - it depends what to say to you authorized service), which cost for you a lot of money, coz you will lose warranty immediately. So if you want to root just for fact that some doing like that without any reasons (to change OS from official to 3rd parties - why need when update is will be official, you have warranty and ect???) - stay away from this idea at all. I recommend you at all don't modify software (if manufacture don't recommend to do some changes even in software). You can easily uninstall some unwanted apps (I couldn't to uninstall maybe only 5 apps from most, but they are still disabled very easily). Smartphone is smoothly, battery is very good. Why at all need to root this device??? Game running very well like: FIFA Mobile, Call of Duty Mobile, NBA 2K20, Asphalt 9 Legend (all in highest settings), if I remember right PUBG Mobile (which was mentioned in other thread and is very popular) worked to me smoothly too, but that game I don't like for strange blue (if I am not wrong) zone where need to run as quickly as possible someone from this zone, but I don't know where. Time always rans faster as I ran. I played it only maybe two time, ok three maybe for some minutes until I was killed by this zone. Don't worry you can play most popular games if you are gamer at all without any problems (i'm sure). Only NBA 2K Mobile lagging in this phone. It doesn't matter in low or highest settings, but how I understand from 2K, this is not phone guilty. As I understand, 2K did not supporting this game for Samsung A70 100% and probably it available in Google Play just for requirements compliance: need Android 8 or higher OS (Samsung A70 have Android 9). RAM must be more as 4 (Samsung A70 have 6 or 8, depends which version u ordered), also good and fast internet connection. There is no reason to lag, but lag is. So probably only these game you can't play from most popular games, I guess. Coz for me did not worked it good. Was big lag, then I bought NBA 2K20, which by the way is much more better as Mobile version. But I saw in Google Play is update for this game already which released December 6, 2019. Maybe already is fixed lag problem. Oh I forgot to write, lag is in Samsung S10 too which is flagship of 2019 from Samsung (I don't remember exactly in which model Note, + or any others, fact that in Samsung any S10 had to run it smoothly, but is the same problem. 2K explain that game is new, models are new, so... can be like this...but maybe will be fixed with future updates).
P.S. I don't know what you doing with smartphone: reading, watching video/movies or listening often music (sounds is not so loud as I expected and on all volume is not good, have distortion a little bit), browsing only or playing games. What is your skill of rooting and ect. I just wrote what I know and my recommendations to do not root. I tried some smartphone to root in past, I know some apps for that, I tried some methods for others phone and ect. So I know how possible to easily lose a phone if you are rookie at all in that. I can't understand at all why need to modify very good mid range smartphone with which you can do a lot of things without any problems? So sorry if my post sounds like scary warning or funny at all, but I just tried to shared my knowledge and experience about root, this model and ect.

A71 Rom for M51

First thing first, I'm not an tech guru, im just a humble guy wondering things. I dont know any fancy terms you guys use. My only experiense is using Android 9 in my 10y/o gt n8000. So if you guys can explain stuff easily, that would be really nice.
As we all know A71 and M51 are pretty similar on paper. M51 is better on hardware and A71 on software (at least that what i know). So i thougt to myself... is it possible to use A71 rom on M51? And if so, would it let us use Good Lock modules and/or let us record videos in 60 fps?
Also another thing... i have heard that using wrong roms on wrong devices can cause pretty big deals, mainly hard bricking the device. I also heard that even if the specs are similar, things coded differently for different devices. Like chipset id, screen size and stuff like that. Is there any possibility to change A71 rom in a way, like rewriting some parts of the code, to work on M51?
Using Good Lock modules or 60 fps camera is not my goal. I know that there is a few trick out there to make it happen. I just wondered that would this theory work? If anyone can help me in this silly project, that would be awesome. Thanks for reading and have a fine fine day.

I don't think it would be possible? As good lock is Samsung's properitory software and are closed-source.
it would take a huge kernel rewrite with driver changes and other technical details that I'm not well versed with ROM development to know about.
Just knowing that trying to recreate Samsung's stock roms would be very difficult or impossible to say at least

Thank you for your answer.
So, let's say we just flash the A71 rom without any changes whatsoever... would it work, what would be the outcome, what's the worst case scenario?
And is there any method or a way of checking if the rom works without sacrificing a phone? Cuz i bought the phone like a year ago and since then it's price just straight up tripled.

It's probably gonna lead to a brick or not even flash because of incompatibility, even if we tried to flash on Odin

Firstly, thank you for answering my dumb questions. That means a lot for me. I really appreciate it.

My question is if that happens can it be fixed, like, via TWRP or by any means? Like a full data / cache erase or something like that can fix it?

Brick? Depends yeah we can just by flashing through fastboot again
