Downgrade from marshmallow to lollipop - Galaxy S 5 Q&A, Help & Troubleshooting

Hi,
I have a Samsung Galaxy sm-g900h phone which I updated to android 6.0.1 (Marshmallow). But after the update the phone's battery life decreased significantly.
Is it possible to downgrade it to the previous 5.0 version. Thanks

As far as I know you can I've done it so you should be good just put into download mode and flash with Odin

Could you please tell me or give me a link of the steps that I should follow?
Thanks

You have to first Install a Custom recovery like Philz Touch, Clean the rom, then flash in the old rom using Odin, or if you have it in .Zip format, its straight after cleaning the rom, go to install from SD card

Please stop providing members incorrect information. Philz is not a ROM it is a recovery. And if he wants to be on stock he needs the official firmware for his device and carrier from sammobile.com and Odin. He needs Philz or TWRP if he wants a custom ROM. However, I recommend a custom ROM over stock. More features and tweaks for the phone. You can also root and get kernel auditor and out it to battery save.

You should try clearing the cache partition and leaving the phone for a week to get used to Marshmallow. I'm on it and it's quite better than Lollipop, just give it some time to settle in

Best advice is to read the development section and see what seems to be popular. I personally look for good stability and battery and look at thread views and the amount of activity to see whats popular. Make a nandroid backup, download a few ROMs that interest you and try each of them out. You can then compare and know exactly what suits you. Sometimes whats good for one, isn't good or another and vice versa, so the best way is to just experiment, you always have your nandroid if things dont work out.
Most if not all custom roms will be flashable via recovery, but there should be installation instructions in the thread and help if you need it.

You can use Odin to flash recovery (CWM, TWRP, Philz). Download and copy the ROM to microSD or internal flash, enter into recovery, backup and flash the ROM (sometime you may need factory reset, use microSD). I have i9500, I use Philz recovery (http://forum.xda-developers.com/showthread.php?t=2201860), Omega ROM (http://forum.xda-developers.com/showthread.php?t=2232887), Perseus kernel (http://forum.xda-developers.com/showthread.php?t=2272602).

[Q] I just want to be sure

Hey Guys,
I'm quite new on the forums, so forgive me if I ask questions that have already been answered a lot. Yes, I've read loads about 'how to root the Samsung Galaxy S4', but I just want your guys confirmation about my ideas.
1. I know for a long time now that you can use the CF-auto root to root your S4. But I'm wondering if it still works after such an amount of updates. Currently my phone's build number is I9505XXUGNG8
2. After my phone is rooted, I would like to have CWM as my costum recovery. I know that a really easy way is to install the ROM manager app from the playstore and from there, flash the CWM recovery. Again I was wondering if it still works that easily for the S4
3. After my phone is rooted and has CWM, I think I don't receive any OTA updates anymore right? (even when I just stay on the official TouchWizz rom)
If I don't get these updates anymore then what is a good way to get the newest Android TouchWizz versions? Can I just use the official TouchWizz roms from Sammobile that will come out in the future?
Already thanks to everybody who comments on this thread!
I hope that I can teach other people also something new.
Anyone?

1. Yes
2. I'm not sure. I always flash first non stock recovery with Odin.
3. Yes, You don't get official updates anymore. If You use latest rom from Sammobile You will loose root. Instead You can use prerooted stock roms easy to find on S4 forum. Or alternatively use any of custom TW based roms. Imo Omega rom is closest to stock.

If all you want to do it install a custom recovery and root the stock rom, you might consider just flashing Clockwork Mod Recovery in ODIN. Then using ClockworkMod to root the phone directly from recovery. It's 1 less ODIN step and it gets you to the same place.

Thanks for your reply! That is exactly what I want to do.
Just to be sure, should I do it this way?
1. Download CWM_6.0.4.7_Non-Touch_GT-I9505.tar
2. Flash the CWM_6.0.4.7_Non-Touch_GT-I9505.tar file with Odin v3.07
3. Download UPDATE-SuperSU-v2.02.zip
4. Boot into CWM recovery and flash the UPDATE-SuperSU-v2.02.zip from the external SD-card (Because I would place it on the external SD-card)
Then I should be rooted right?

Yes.
And you can replace the version of CWM you mentioned with any other recovery that makes you happy, as long as it's a .tar install file for ODIN.
Why the non touch version?

Thanks A LOT!!!
I prefer the non touch version, because I'm then just a little bit more confident that I don't misclick because of touch (although that probably won't happen) and I think that the volume keys are therfore just a little bit more accurate to navigate with,
Also, if I have CWM installed and rooted my phone, can I then just install ROM manager to keep my CWM recovery up to date or do I have to flash a new one to get an updated version?

You don't have MF3, and that's a good thing. You can install a custom recovery. You need to root, install a custom recovery, and then you can start flashing roms.

Ok, use TowelRoot.com to root the phone, and use TWRP manager to install TWRP on your device. After that check out the development section of this very forum and flash any ROM you wish. 4.2.2 or 4.4.4 or 5.0 or anywhere in between (Just read the thread and instructions first!!!). Whatever you do, never update using the OTA updater on the stock ROM! Also, dotn ever flash an image in Odin that isn't MDL, because if you go higher than MDL, you lose the ability to have a custom recovery. You are one of the lucky ones, cherish the ability, and read through threads before flashing, stuff. Good Luck!
Also, you don't have to worry if the ROM says safestrap compatible, because you don't have to use Safestrap, you can have TWRP instead (which is better), because all Safestrap ROMS are TWRP compatible, but not vice-versa.

Most if not all. They're all built from either GPE or CM.
All good advice. Plus when you root and get Twrp recovery installed do a backup thru Twrp (Nandroid) and keep on phone and put a copy on pc. That way you have something to restore if you get in trouble. Also, your bootloader is not unlocked. No Att i337s are. Instead devs use an exploit called Loki-Doki to bypass Sammy's security checks to allow custom roms/kernels etc to flash. You can google Loki Doki and read up on it. If the rom or kernel is not loki'd you will have to flash the zip thru recovery to allow the rom or kernel to flash. You will come across this when flashing International roms and kernels. I don't have link any more so maybe someone else can link it. Keep it on SD card. Like noted read OP carefully and last 20 pages of rom thread. Builds newer than MDL are blocked by Att from using Loki and require SafeStrap. Which you don't need to worry about. Although you can read up on it. Good Luck. [emoji1]

I hope you won't mind me jumping in your thread.,
I've recently had to odin my mdl phone back to stock. I haven't done that in a long time. I have root, and supersu, and busybox. The TWRP Manager app is malfunctioning and I cannot use it to install recovery. They list the crash I am experiencing in the play store as a known problem, and they say it will take time to fix. I have a good loki'd copy of twrp but the stock recovery doesn't want to install it. I even changed the name to "update.zip" and it fails. So my problem is I need a recovery. I am considering installing Clockworkmod's ROM Manager to install their recovery, and then using their recovery to install the good loki'd twrp that I want. Does this sound like a good plan? I have been away from this hobby for a while.

You can flash a recovery zip in a custom recovery. So if you have the loki'd twrp in a zip file, flashing cwm first will work

Thanks man, that's exactly what I was planning. I remember avoiding CWM last year due to some issue on this device so I just wanted to make sure it wasn't going to do more harm than good. :good:

ROM manager didn't work. It said it installed cwm recovery but it didn't. I was able to install the latest TWRP with this ROM Installer and it worked like a charm! I then installed my custom TWRP from there, rebooted recovery, and installed Danvh's Google edition. I'm setting it up right now. I'm so happy to get my phone back. I just hope the odin flash fixed my problems.
To the OP try ROM installer to get your custom recovery going. Also if you like simple and fast AOSP check out Danvh's google edition rom, but stick to 4.4.4 for now. 5.0 is out but its buggy. Here's a link to the custom version of twrp that I use. https://www.dropbox.com/l/iDQQqlzNbyiFbQrMF4XcRc It's already loki'd so you can flash it if you have any problems with the latest build.

Take just 1min out of you time and help me if possible :)

So I know these questions have been probably asked and answered a million times already, but honestly, I haven't been able to find answers exactly for my questions.
I will try to keep this as sort as possible, all I ask is to either point me somewhere or answer with a simple Yes/No. Of course longer responses are welcome as well
My info:
*SM-N910F *trlte *Firmware CSC code- TTR *Bootloader/PDA/Baseband- N910FXXU1COH4 *5.1.1 *LMY47X.N910FXXU1COH4 *If more is needed just tell me.
So here we go:
1)From what I understand, for installing a custom ROM, TWRP is the first thing I should install. Correct?
2)Which is the latest Odin version (or which version should I use) to install TWRP?
3)Is it possible to install any STOCK rom from SAMmobile or only the ones specific for my country?
4)After installing TWRP and making a backup, which application should I use to root my device and which one to make an EFS backup?
Thats all, thanks a lot in advance everyone
1)I would recommend installing a custom rom but thats a personal choice 2)I believe the latest is 3.10 but 3.07 works just fine 3)Any stock Rom for your model 910f 4) If you install a custom rom it will be rooted already if Stock CF-Autoroot should work but do it before changing recovery as it puts the factory one (3E) back also TWRP will let you back up your EFS

I have but I have a 910w8 so I use the T-mobile version no modem required
But you can pull the modem out of the MD5 file (odin file) using winrar or something like that and flash just the modem in odin or just find a flashable zip for your model
personaly, i tried every custom rom there is for the n910F version, and none of them was good to keep, one's drain to much batery, the others lack features.. so currently im on the stock 5.1.1. german rom, with root, and its amazing for my needs, stanby time can go easily 3 days, SOT 4h

To flash a Custom ROM there is no need to root, the only thing you need is to install a custom recovery, TWRP is very good. After you have installed TWRP or any other custom recovery, you have to put on your SD Card the ROM that you want to install, and install it from the custom recovery.
