So I got a new galaxy alpha (850F) which is an amazing phone by the way but i have a few questions
1) I noticed that sometimes the signal drops to 0 bars for a few seconds then comes back again, is that normal because of the metal frame or what ?
2)How much does the battery take to charge ?
3) I am still on Kitkat 4.4.4 and the lollipop OTA hasn't arrived where I live yet (I don't think it's coming anytime soon) so what's the best course of action, should I stay on kitkat ? Which official rom can I flash using ODIN ? Is there a toolkit for rooting and installing a custom recovery ?
If there are tutorials for these things I'll be thankful.
Hi Mazika2,
1) I have no idea and never experienced what you describe
2) For me battery charging takes about 1h - 1 1/2h with original charging plug (over USB on PC it takes much longer)
3) You can flash any 5.0.2 ROM via Odin.
Root 4.4.4: You can take Kingroot for example, Knox will not be tripped.
Root 5.0.2: http://www.skyneel.com/2014/09/root-samsung-galaxy-alpha-sm-g850f-by-simple-tutorial.html . Knox will be tripped.
Custom recovery: http://forum.xda-developers.com/galaxy-alpha/orig-development/recovery-twrp-2-8-clockworkmod-recovery-t2923587
Is there anything to reset knox like triangle away ?
I read a few threads about flashing stock firmware, what are modems and hidden.img ?
Which is better in terms of stability , battery, etc... kitkat or lollipop ?
And finally let's say I want to upgrade to stock lollipop using ODIN what are the steps to follow ?
sorry if these questions sound nooby .

1. Issues were noticed on this subject, mainly with 4G network. I changed to 3G and I hadn't more missed calls. I think the problem is more related to inconstant network signal than to the phone itself.
2. With the original adapter is really fast comparing with my old device. I never counted but something like one hour or less.
3. There are people who prefers Kitkat over Lollipop due to better responsiveness. Mine came already with Lollipop so I haven't comparison. For now, I don't have the need to root with custom rom's, the Alpha is superb as it is (except for the annoying touch screen issue...)

Can I flash a SM G850F firmware on a SMG850M?

Knox can't be resetted once it is tripped! Keep that in mind. In terms of stability and battery I would say they are the same. It depends mainly on your daily usage of the phone.
Steps to follow upgrading your firmware with odin can be found here: http://www.pocketpc.ch/samsung-galaxy-s6-s6-edge-root-und-rom/226170-anleitung-flashen-firmware-odin-samsung-galaxy-s6-edge-sm-g920f-g925f.html

It's complicated, for two reasons I know of, probably more.
1) I'm not sure the chipsets in the F and the M are the same. I know, for example, that the A is Snapdragon and the M is Exynos. I think the F is Exynos, too, but I'm not positive. You'd need the same chipsets for it to work.
2) It's likely the F and the M have different modems, so if you flash F firmware on an M, you may end up corrupting your EFS folder and blacklisting your phone's IMEI on your carrier. You'd need to find out exactly what frequencies the F supports and make sure the M supports them, too. I've read there is a way around this by somehow re-loading two modem files from your phone's original firmware after installing the other phone's firmware, but I've not found step-by-step instructions that are simple enough for me to understand.
Even if those two issues are resolved, it's still dicey. I really want to find SM-G850T firmware and flash it to my SM-G850M, so we are in a similar boat. I can't even find someone who owns a SM-G850T, let alone the firmware. (I did find a question posted on another Site by an individual who said they own a SM-G850T. Unfortunately, half a dozen emails to this individual have remained unanswered.
so here is what I'm planning on doing
1) while on kitkat I'll root with kingroot without tripping knox to backup the EFS folder
2)flash official 5.0.2 using odin
3) try lollipop then decide whether to stay on it or downgrade to kitkat
I just want to know some things before doing the steps above:
1) what are modems and hidden.img in official firmwares ?
2)after rooting on kitkat, can i flash lollipop directly or do i have to flash official kitkat firmware to unroot then upgrade to kitkat ?
I don't know the answers to your questions: I'm even noobier than you!
I do know that when my SM-G850M upgraded to Lollipop, I HATED it. It ran slower and was choppy in the display animations, it cut battery life by at least a third (with no change in anything after wiping the cache), and I especially hated the new color scheme. So, I went back to KitKat. Had to do a Factory Reset to get the phone out of bootloop, but it was fine after that. EXCEPT, the Lollipop downloader reminder stayed on there and I was not able to stop the app or clear the data (those options in the Application Manager were grayed out. So, I flashed the SM-G850M with KitKat firmware from the Dominican Republic (Orange). I read somewhere that Orange was not planning on releasing Lollipop for their Alpha, so I figured this firmware would be Lollipop Downloader Reminder-Free. So far, so good.
The battery drain of Lollipop is driving me crazy and since theres no way to go back to kitkat Im stuck with this so I wanna know if theres a way to update to marshmallow
There will be no way to go to marshmellow as there is no Sammy base to build on and there is no bootloader unlock.
Just go to Stang's Lolipop ROMs and get the modules which greatly helps with the battery drain.

even after sammy update all devices to marshmallow (S7, S6, Note 5, S5, etc.)?
Yes. They have dropped support for the s4. It's not that it can't run marshmellow so much as to get people to buy their latest phones.
The only S5 Kitkat ROMs I've found either haven't been updated in over a year, or many users are reporting severe bugs like no camera support, or severe battery drain issues.
I'm just trying to get an app called Winulator running so I can play Starcraft: Broodwar on android, but it isn't working and one user said that is because Lolipop broke it (I'm on 5.1.1 atm). The app is no longer supported so I don't think it will ever run properly on 5.x. If anyone knows of a way to emulate 4.x for just 1 app maybe that would be the best shortcut for me overall here.
Barring that, could someone please recommend a guide to installing a lightweight, power-user-oriented ROM that is 4.x or older and has excellent battery life? I was going to try the official 4.4.4 VanirAOSP release but there are too many reports of poor battery performance in the last 2 pages of that thread for my liking.
I think the first thing I need to do is unlock the bootloader, and I've yet to find a definite answer on the best method of doing this from FOL1 (12/15). It seems I will need Odin on my PC and I have it. I've also started backing up all the data from my phone by manually copying/pasting to my PC.
I guess once everything is finally backed up (it's taking FOREVER, explorer literally been calculating time to copy for 10 minutes now just on the phone/android folder), then I will try and flash the official 4.4.2 VanirAOSP ROM since that one doesn't have any reports of battery issues and possibly only the camera and a few things won't work.
BTW, is there a step specially to unlock the FOL1 bootloader that I am missing, or can I just flash that ROM with Odin straight up? I found a comment stating NOT to flash 5.1.1 with Odin or I'd be stuck on Lollipop until some new bootloader-unlock method comes out. The 5.1.1 I'm running wasn't flashed with odin it was sent OTA and I've never rooted or had custom rom/bootloader, so I should be good on that I guess?
I am actually about to dive into this, if no one has any suggestions for me: http://forum.xda-developers.com/showthread.php?t=2752995 (don't bother, too many missing major features)
edit: I used this guide and it was quick and painless, highly recommend! http://forum.xda-developers.com/tmo...l/root-how-to-root-sm-g900t-firmware-t3358190
Unfortunately the "sick n twi5ted" rom that I chose to install (only because the 600+ Infinity ROM thread has broken DL links) is a buggy PoS on the g900t so I'm still looking for a decent rom.
so i tried rooting my samsung galaxy s7 nougat with jrkruse root for oreo. so basically i didn't read because i was on a lack of sleep and thought that i would be able to gain full root access, well nougat didn't come with a root only a few mods and i think a custom ROM. well the problem is that i want to update to oreo so i can gain full root access but i cant OTA update because of the custom rom situation. so basically ive been trying to find a way if theres a way i could just reset my phone to a stock firmware or if theres a way i can force the update. please help with suggestions on the quickest way.
Last time I tried rooting was in 2016/2017 using Super SU but now many years later I want to try to root my phone again. I have Galaxy S21 ( Exynos ) and I was wondering what would be the easiest way that won't cause too much trouble.
What are the pros and cons of rooting a phone in 2021 and are there any dealbreakers like not being able to recieve system updates or banking apps not working at all.
I would also like to know if there are any android 10 based custom ROM's for Galaxy S21 currently?

In order to root you need to unlock your bootloader, which means no system updates. Most apps will still work if you install Magisk (SuperSU equivalent). There are not really any roms yet, but you can see that easily from the rom section of this forum:

Hi,
Since there's no custom ROM for this model, I wanted to try the GSI way.
I've installed TWRP on my S21 (o1s) following this procedure : https://forum.xda-developers.com/t/...-for-galaxy-s21-exynos.4241869/#post-84592059
Then, I flashed /e/ OS from here : https://images.ecloud.global/dev/treble_arm64_bvN/
However, the phone keeps bootlooping after displaying "This phone is not running Samsung's official software. You may have problems with features or security, and you won't be able to install software updates."
I believe I'm missing a step in my installation (something about vbmeta maybe ?). Can anyone help me ? It's my first time dealing with recent Samsung phones (= post-Galaxy S9).
(I've also posted this question here : https://github.com/phhusson/treble_experimentations/issues/2006)
