downgrade 8.0 to 6.0 a520 - Samsung Galaxy A3, A5, A7 (2017) Questions & Answe

hi, I'd like to know if there were any way I could revert back to marshmallow without bricking the device. I was thinking about rooting my phone, download the stock a520 6.0 rom zip file and flash it with the recovery menu. First I don't wanna brick it, second I'm not sure I can find some flashable zip file.
I did this with my old Motorola moto g 3 and never had any problems.
do you guys think it'll work and so where I could find those files? also if there's any other safe way to do it share it please!
Thanks in advance!

I don't think it will work because Samsung has anti rollback in its phones which prevents the bootloader from being downgraded. However, a system and boot flash might work. I don't know about the modem though.
Samsung is one of the few brands that implement it.
I don't really see the use though as it is quite possible to bootloop and if done incorrectly, could result in a hard brick.

Quick question...
Why would you want to?
I did this with my old Moto X Play and bricked it

that is what I thought... I think the only real solution would be to find a custom Rom of the Stock 6.0 but untouched. It would not need the bootloader to be downgraded would it?
I really like samsung phones but I hate the way the treat costumers, it feels like being fooled.
Thank you for your reply though !

When I bought my Moto g 2015 it was very fast and that was surprising. All the updates started to drain the battery and make the device work slower . I tried almost all the custom Rom possible and after flashing back the stock 5.1 out of the box version I have to admit they wanted the device to become slow with all the updates.
Now when I received my A5 it was already running nougat. I think the best you can get from your phone is with the outbox version because everything is planned to be running perfectly so people buy it. For me even though it brings new features and stuff, update wont get you device any better.
So ya that's the reason I'd like to downgrade.

You could extract the system and boot out of the stock firmware, but I don't know if it's worth the risk.

Motorola got in trouble for that. Others too. It's illegal now, so you should leave out that theory.
I've had only positive experiences with my last 5 smartphones. Upgrading does precisely that...makes it better. An OEM would not produce an upgrade without testing it. That's why we had a better experience with Nougat and even better with Oreo.
What do you do differently with Oreo than you did with Nougat?

New Nexus Owner Seeking Advice

Hi folks! Just received a 2013 Nexus 7 from my fiancé as a birthday gift. I wanted it for quite specific purposes so was hoping I could ask a few questions here and get pointed in the right direction before I start using this thing
I intend to mainly use the tablet for remote play with my PS4 and emulating old console games. Since I want to connect a PS4 controller to it wirelessly I'm told I need to root the device. I'm guessing this is an easy process and there are some guides on the site here?
The main thing I was after advice about is firmware updates. The system came on 4.3 and has already downloaded an update for 4.4.2 but I haven't installed that yet. Is this firmware fine to upgrade to? Any performance issues? I've heard people saying that upgrading their Nexus to 5+ (Lollipop?) has created a load of performance issues and this should be avoided? Also, if I upgrade to a certain firmware version can I lock myself out of being able to root the device? I'm pretty sure all of the apps I was planning on using work no 4.3 so I have no reason to upgrade at all but if I can go safely to a higher firmware that is reliable with no performance issues I may as well?
First time using an Android device so sorry if my questions come off as a little stupid. Also, wasn't sure if I should post this here or if it should be on the Q&A board so sorry if I've got that wrong!
As far as I know, the problems with lollipop were the standard number of complaints that come with any new release. Well, I'm not really positive, but lollipop seems fine to me and I think most people have upgraded by now. I would go for it because I think it's really fun to use.... Plus you can always revert if you choose.
As far as rooting, you never need to worry about not being able to do it... Rooting your Nexus 7 will always be easy. The by-hand method is fun and relatively simple, or you can just use the toolkit in the forum to do it even easier.
^Yeah I'll echo that. Lollipop is good. The people having problems don't know what they're doing. Flash the factory image.
If you want root you can use cfautoroot or simply flash twrp with fastboot then flash the su.zip
Personally, I'd stick go for 4.4.4, as 5, 5.0.1 & 5.0.2 all have a memory leak issue. You may also find more emulator compatability as Kit Kat has been around a year longer than Lollipop. The only downside to KK over L is the battery life is a little worse IMO.
I dont think the memory leak issue is a result of someone not knowing what they are doing etc.
Thanks for all the advice everyone

I'm fairly competent with computers (as I should be with a degree in computer science!) but this is all like a foreign language to me. I guess I'm better sticking with the toolkit for now until I'm familiar with all the lingo?

Thanks. This is the sort of advice I was after and is why I mentioned what I was planning on using it for. The device has already downloaded 4.4.2 and wants to update to that. Is there a way I can manually go to 4.4.4? I'm worried it will just request an update from the Google server and try to jump straight to a version of 5

If you unlock the bootloader then familiarise yourself with ADB and flashing factory images, you can manually flash any version of Android (That has been availible for your device,) manually. You dont need to be rooted to do this.
It also allows you to go back when you've made the mistake of updating, (but does wipe all of your data!)
It ended up offering me the updates incrementally anyway. I went from 4.3 > 4.4.2 > 4.4.3 > 4.4.4 which I'm currently on and will leave it there for now. It's downloaded 5.0.2 but I've skipped the install for the time being
Think I need to do a little reading up before I root the device as I haven't got a clue what some of you are talking about haha. Thanks for all the advice so far though
No problems.
I've had a few Nexus devices and never felt the need to root them. :angel:

The majority of problems stem from Qualcomms crappy broken mess Adreno gpu drivers, hence the delayed
rollouts of Android for the Nexus 4 and 7 that both use the Adreno 320, don't be suprised if the Nexus 4 and 7 get a
Android 5.1.1 release instead.
For ppl new to nexus devices, wugfresh nexus root toolkit is a great tool until you get the hang of adb and fastboot. With a nexus you can always switch between android versions. You can always root, or go back to older versions of android. Updating to newer versions never hurts anything because you can always go back. Its a developers device so its very versatile. Try lollipop if you like, (I love it) and if its not your thing, just flash back to 4.4.4. I love this tablet.

You for got to mention the disclaimer if your tab came with 5.x.x out of box you cant go back to KK. Also a lot of us who recently bought Nexus 7, I have 3 that I have acquired, came with 5.0.1 installed are having issues with partitions/memory mounting in recovery. Some sort of revision done in the latest batch sent out. If his tab came with 5.0.1 or higher and has his bootloader at FLO 4.04 he may have problems trying to go back with either bootloops and what not.

Help new to this!

Hi guys and girls i am from the uk (england) and got my g4 about 4 months ago.
Fed up of lg's stock rom and how its very laggy and irritating to use now.
I have been looking everywhere about rooting the phone and installing custom roms to make it much better and more enjoyable to use.
But i am stuck i dont know whats the best way of rooting this phone i have tried booting it into stock recovery mode but it just dont work.
so can you guys please point me to a right good method of rooting and installing custom roms please?
Currently using android 5.1 on lg stock rom
Many thanks!
Take it that is a no haha

Have you unlocked your bootloader ?
No not too sure how to do that. Any good threads you guys reccomend.
Many thanks
So I know this is scary for you and because it is something new, therefore be sure that you want to live with the responsability if something goes wrong.
Now, the next forum thread tells you how to flash an already rooted image BUT, and this is very important, this works only if you have the version 10c installed (Check in About Phone>Software Version)
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
If you have the latest version of the software (20a) the best thing is to unlock your bootloader, void your warranty in the process, and flash a custom recovery. After that, you just need to flash the SuperSu zip file and you will have root.
To flash custom ROMs, just access recovery and flash the zip file of your ROM.
I'm using the unofficial CM13.0 and works very good for me, but I do miss the official camera app.
Thankyou very much for your advice okarr. Will look into this

Do not take APH1 Update!

After taking the APH1 update on my phone, I can no longer downgrade to PG5, and I also can't flash the PG9 U firmware. I don't know what Samsung/Verizon did, but it's ridiculous.
I'm now stuck on the APH1 firmware and can't get on the U firmware at all.
I haven't tried rooting, but there is no Odin firmware for APH1 yet, so I'm not going to try until there is, so that if I mess up my phone I can fix it.

It probably incremented the bootloader. I upgraded to it because I am just losing interest in root all together. Somebody will chime in with a more technical explanation.

Agreed. For some reason I just don't really care about rooting the S7. Maybe I've just rooted too many phones and lost interest.

For me a lot of it is this is not the most conventional root, not very stable for me and battery life suffered a lot compared to stock, and flashing U firmware has not been very cooperative for me.
So thoughts.... I am on the latest U firmware on my 930V. Should I consider flashing back to the stock Verizon rom? Everything is working great. I do plan on jumping ship from Verizon in the next year or so. I am blown away at how well this phone runs stock and only flashed the U in preparation to take it to another carrier afterwards. Is this a bad idea?
Tried to live with root, but the battery and stability was horrible. Now, I am using the engboot to do any data back up or restore tasks in TiBU then flashing the AP again to unroot. Data is maintained, but now I have to live with ads. I use adguard, by it feel like it hurts battery life. Will try and quantify that soon.
Being able to count on my phone to make a call and hold a charge is too important to me. Rooting the phone to set it up after a reset saves me time. Unfortunately, rooting with our current method is too prohibitive for daily use.

Same here.
I have a 930U that I use on Verizon. I use the 930V firmware because I like having visual Voicemail. I have rooted 3 different times and gone back to stock everytime. I suppose it because of the engineering kernel but root with the S7 is just not stable. The battery life sucks and you have to do so many things to fix the lag it has just become not worth it. Also the 2 latest updates from Verizon have been good on battery. I do like not having Verizon logos all over my phone.

Been using the same ROM for almost a week with xposed and everything is fine. I feel great without seeing the ads again. haha! BTW, I didn't try the nearby devices so no comment on that.
I have the G930V and am running APH1 with root no problems. The lag was horrendous but after changing the CPU governor to "interactive" on BOTH CPU's (little and BIG) it's been running smooth. I'll run like this for a bit... but stang5liter looks like it will be my next move.
Has anyone with ph1 tried flashing another rom such as stang5litre?

PH1 doesn't break root. You just can't downgrade to older firmware's or flash any U firmware's. PH1 is still completely rootable.
So you can't Odin flash back to a stock image if you get in trouble or want to unroot. I guess I'll stay on PG5 for now.
I'm not rooted now, but was able to disable system update notifications using
https://play.google.com/store/apps/details?id=com.hecorat.packagedisabler
By disabling:
System updates (com.samsung.sdm)
System updates (com.samsung.sdmviewer)
and securitylogagent

Im somewhat confused. Your saying you cant downgrade from ph1. Are you talking only with odin? Reason i ask is stang5litre rom is APE1. And as was stated a few posts up, this rom can be flashed on rooted APH1. Which would take you back to APE1. Therefor downgradable? Any help is appreciated.

Ph1 upgrades the boot image therefore you cannot Odin flash back to stock pe1 which is the older boot image.
You can still root and flash stang5litre which is the pe1 rom, but you still have the ph1 boot image.

The ph1 image is available at this link (http://updato.com/firmware-archive-select-model?record=78F84FCD811E11E69B2DFA163EE8F90B). I have flashed with these files and they work perfect.
Seems bootloader was uograded to version 3. So may be possible to flash between tmo and vzw and vice versa. Both now have v3 bootloader.

Downgrading 6.0.1 to 5.1.1

Hi if anyone can help- I'm on the Verizon Samsung Galaxy Note 4 after 2 Note 7's and a Note 3 before that on Biggin's so I've sorta been out of the root game. I want to downgrade from 6.0.1 to 5.1.1. I am downloading the full firmware for the Note 4 from further back in this thread (N910VVRU2CPA1) and am currently on (N910VVRU2CPG2).
From what I understand, I need to do a factory reset, then go to Odin and flash the firmware. I have Odin 3.10.7 and am downloading the N910VVRU2CPA1 as we speak. I see 'hsbadr' firmwares in his thread and the PIT file TRLTE_USA_VZW.pit which I'm not sure is compatable pit file for the specific 5.1.1 firmware or the necessary pit file is included in the full firmware and can anyone tell me if these are the right steps?are these the right steps Any information would be greatly appreciated,
Thanks

Before you can start rooting, you'll need to be on 5.1.1 BPA1. If you're currently on 6.0.1, just download the BPA1 firmware from Sammobile, factory reset on 6.0.1, then flash BPA1 stock via Odin.

Hi thanks, I had called Samsung and talked to top tier tech support and was told that once the phone has been upgraded to 6.0.1., it cannot be downgraded. and that i need to search the rooting sites and try to find where someone has found a breach or workaround for unlocking the bootloader which will usually have a bounty but I dont know. top tier tech support has always been good. Do you think thats false it cannot be downgraded?

I don't even know if that matters.. Anyway, the two 5.1.1. builds are PA1 and OK3. Do you know where any other firmwares out there that might show my current one and the previous build that it came from?
Thanks-

Yeah they're out there but that thread hasn't been updated recently. Basically the order after pf3 is pg2, pj2, and then cpl1. The one you want, if your planning on rooting, is bpa1. Also, as far as your question in the op about the pit file, it should really only be used if absolutely necessary. It's in case your partitions have been corrupted for some reason and you need to repartition your device.
Edit- I was going to link to those other firmwares but they are buried in the thread that your already looking in. Either way they aren't necessary for you to unlock your bootloader, you can go straight from cpl1 to bpa1.

Hey thanks for confirming all this. So all I need to download and install is the bpa1 firmware via Oden with the AP button I think- I've got a few different versions of Oden on my pc. It's been a while since I've flashed firmware on a phone but I remember it was easy. So just save my pictures, any files, etc. on the sd card, remove it, then do a factory reset or when I put the setting into usb download mode, and flash the firmware this will automatically factory reset the phone? Also earlier today Verizon has been trying to push an software upgrade. After I unlock the bootloader and install twrp then flash a rom, do I need to somehow disable the update notice. I remember having to do that once with another phone.
What rom are you on? Thanks again for the Info-

Yeah that all sounds spot on. I would definitely do the factory reset before you start, but other than that your good. To block the updates, you can uninstall the SDM apps. There are 2 of those and you'll need root to remove them, but you can disable them without root with that debloater tool. The rom I'm currently using is kind of work in progress. I have a couple stock based roms in the dev section, one is stock_plus that has a stock feel with some mods added and the other is Modest Rom that is got some grace apps added and system ui mods. You can find them here and here if you want to check them out.

Awesome, I'm going to check those out but I forgot the biggest question of all... how to get rid of the Galaxy lag- is there a rom or tweak where this can be fixed since recovery cache delete and cleaning tools dont really do much?

Custom kernels help a lot. The problem is it's kind of slim pickings for our specific model, but some of the international kernels work well too. Oscar kernel is made for the 910v so that's probably the most reliable but if your like me, I like to use a permissive kernel and Ram kernel is not a bad choice for that though it's not as feature rich.

I really dont know the difference... from what I remember a kernel is the layer between the software and the hardware- a key component of the os. I'm guessing the permissive ones can be used for different roms or firmware? You can probably tell I really don't that much about the root game. The last time I flashed a firmware was on my note 3 after I bricked it. Then rerooted and got on to biggins rom which was great ut I never understood or learned how to use xposed. Anyway, I downloaded Modest Rom, PJ2 _STOCK .tar and am downloading cpl1_tar but I know that once I flash bpa1 firmware which puts the phone back on 5.1.1. I see your roms are 6.0.1 roms, after I flash the bpa1, will the bootloader be unlocked? If so can I then just flash the cpla1_tar or is that not a full firmware? or use one of the two 6.0.1 firmwares from where I found the cpa1? Are the kernels different from 6.0.1 and 5.1.1 and where to find the downloads?? I appreciate the tips especially coming from a develpoer and i'm happy to make a donation- I'm not sure how?
Thanks again!

Hey buddy, did you get it figured out? I broke my arm at work on Sunday and of course it's my right arm so I'm having some issues responding back on my note with one hand. I bet I've dropped this thing 20 times already.

Oh man that sucks- hopefully they gave you some good pain meds. Anyway, I havent taken th plunge yet- once I get on to 5.1.1 then twrp, I want to go on to 6.0.1 but am unsure as to what point the bootloader is unlocked or exactly what to do to upgrade to 6.0.1 once I crack the bl. I just dont want to go through the dreaded set up everything twice.

Looking for some help getting off Vzw ROM to custom

Hello all,
Long story short I currently have an Unlocked 10, rooted, s off, and bootloader unlocked. I have flashed over the Verizon rom and radios last year and left it this way for a while. I'm getting to the point where I'm about ready for a factory reset but figured I might as well update if I'm going to do that. Better yet I'd like to get on LeeDroid but preferably on Android N.
So I need to update to an Android N ROM first, then over to LeeDroid. I can do it, but frankly I do this stuff so little that every time I get a little nervous. My 10 is my daily driver but I currently have a raggedy s6 here I can pop a sim in for a minute if needed.
So I'm wondering would it make sense to just do a backup, flash the latest Unlocked N version then flash LeeDroid? Wouldn't my Verizon radios stay where they're at, or will flashing those roms over write them? And, none of this flashing should overwrite my recovery, should it?
Also, I apologize if this is not appropriate but my other option at this point is to ask, are there any fairly well regarded XDA friends here with some spare time that would be open to taking 20 bucks or so to get me fixed up remotely over teamviewer or something?
Thanks for all your help. I don't post here often but when I do I always find the direction I need as someone who is not a frequent modder anymore lol.

To minimize potential problems I would start fresh going from M to N.
Flash the full N RUU.exe. Flash the latest TWRP, then flash LeeDroid. New firmware, TWRP, and custom rom.

Would you suggest Verizon N rom since I'm already on Verizon M or would Unlocked N be better?

Get a copy of your current M rom for the firmware you currently have and download that. Remember, we're talking full roms not updates. Now get the latest N rom for your device (full ruu.exe). Now you have options. I would flash the N rom, then the latest TWRP, then LeeDroid. Any problems, and you can go right back to M. I always use TWRP 3.0.2-6 with M. So if I go back to M I flash that version of TWRP (from within TWRP itself) first. Take your time. You can do this. You can get the latest N rom from HTC's website. To get your M rom you'll have to search for it using your firmware numbers. Someone should have a copy.
BTW, you can watch ROOT JUNKY's videos on youtube as a refresher on the basics of flashing TWRP and so on. Don't use his files though. They're old.

Yeah I think you're right. I made it this far lol. But the N rom from HTC would just be the unlocked N wouldn't it, not Verizon? I know the Verizon ruu is over in the Verizon HTC 10 forum here so I could get that. Also I think I need to go brush up on firmware vs rom I tend to think they're the same thing but they're not, right?

I see. By "unlocked" you mean the US unlocked GSM HTC 10. I wouldn't mess with trying to alter your radios right now. Yes, stick with Verizon on everything. LeeDroid should run fine with that. Installing a new HTC rom changes your firmware. It will be updated as you go to N. If you decide to back to M, it will be downgraded. Installing a custom rom won't change your firmware. A full rom is composed of several components. The firmware is one component.

Ohhh okay I follow. Yeah sorry I did mean the GSM Unlocked model, I bought direct from HTC. But I couldn't get it to work on unlocked firmware with Verizon so I ended up flashing the Verizon ROM and radio last year.
So I'll grab the Verizon RUU and flash that, then LeeDroid. And update my TWRP. Its long over due anyways lol
Can't thank you enough for your help. I'm going to give it a shot this weekend I think. I really want to run LeeDroid!
