Downgrade from OS5 to any ver 4 - Fire Q&A, Help & Troubleshooting

I really dislike this new interface on my HDX 8.9. Any way to downgrade to a version prior to the upgrade?

Has not been demonstrated. Risk of bricking if v4/v5 bootloaders are incompatible or contain anti-rollback protection. Suggest contacting Amazon.
Edit: Wrong forum for HDX devices (but answer remains the same).

Yeah, took me 20 mins to get Amazon to assimilate that I wanted to downgrade and not upgrade.....hard work. I gave up on them!

Galaxy S6 Edge 925A 5.1.1 Root/Downgrade/TWRP Questions

I purchased a S6 Edge and it was updated to 5.1.1 when I got it. I am a big fan of rooting/flashing ROMS/mods (My last phone was an extremely modded Oneplus One which met an untimely end) but I am not really sure how to do that on this phone. I would very much appreciate any help with info on how to root/install TWRP. Additionally I know that the S6 on 5.0.2 can be rooted but I also heard that once you update to 5.1.1 can't downgrade but it's worth a shot. I also heard that the [email protected] version has a locked boot loader is there any way to unlock it? If not would flashing say a T-Mobile stock ROM work? Thank you for any help. I also know that Devs don't like being asked for ETAs so instead I will ask if anyone knows how development of Cyenogenmod for the S6 Edge is progressing?
There's no way to unlock the bootloader on the AT&T version of the phone. You won't be able to use a custom recovery such as TWRP.
This is also my first Samsung phone (I've always used HTC devices, which were so easy to unlock/root). Since you're on 5.1.1, I don't think there's any way to achieve root (yet). I may be wrong there, though.
There is no way to root, if you want to do fun stuff with your phone, stay away from at&t

Hi, I'm also in the same boat. I know that this thread is old but I am planning to buy the s6 edge with AT&T (used). The phone is currently running on 5.1.1, (OJ9).
Before buying, is there any possible root YET? Am I possible to downgrade? I am sure these questions have been answered multiple times, but like I said, the threads that I have found via XDA are old. So before purchasing, I'd just like to make sure. Thank you so much!!

No and no , the only hope we have is when we get android 6 and wait for any possible new root method.

Are people working on cracking the AT&T G870A or is it a lost cause?

Are people still working on cracking the AT&T G870A or is it a lost cause?
If yes, how's it going?
I had a G870F but sent it swimming on 20m deep for three weeks. Needless to say it didn't survive.
Found the G870A and thought it was a bargain, however . . .
Pretty much a lost cause, most devs have moved on.
So the answer is not so straight forward. The current v 5.1 and above for the AT&T phones are not currently rootable. If you find a used or remanufactured S5 or S5 Active with 4.2 you will be in luck. I just had a problem with my Active found a replacement on the most popular buying and selling web site for around $230. Just make sure it has not been updated. If the seller is advertising it as 4.2 and you get it with 5.0 they must take it back if it's not what was advertised. Hope this helps.
If you want an S5 to tinker with you should get a tmobile variant the SM-G900T, or the international SM-G900M since the active model is basically a carrier exclusive they dont have any international ones that im aware of.
I dont understand the question of OP
I used a popular search and found rooted firmwares for the 870A.
Several people who replied have in their sigs that they have a rooted s5 Active..... I would think that to mean the phone has been "cracked" and isn't a lost cause.

Thanks, but I have bought the phone already. If I get another one or replace the one I have it'll probably be a European, G870F, the same modell I had before.

You could have rooted before 5.0. If you have the latest bootloader, it can't be done. That is why I suggested getting one that has pre 5.0 stock 4.4.2.

so its isn't the android version per say bu the bootloader that comes with it?
So one couldn't just flash a 5.0 firmware, is that what you're also saying?
pardon my ignorance, but when one flashes a firmware -- that wont impact the bootloader will it...
poop... i just got one of those and I'm all excited to get the att crap off there and see how much faster it gets... not to mention all the other things you can't run without root.... this ebay "deal" keeps getting worse....

When you update the firmware, it automatically updates the bootloader. Once that bootloader has been updated, it's locked down. No downgrading firmwares, rooting, or installing custom recoveries.

Yeah, that's basically what I gathered after a lot of research online.
Some claim it can be done but when trying the method/software, it doesn't work.
I just wanted to double check since there is a lot of expert knowledge in this forum.
One thing i've been thinking though (not that I can do it): how about picking the phone apart
and wiping/replacing the bootloader manually?

Well it's soldered to the board. You would need some highly specialized equipment to do it. Even then I'm not sure.

Is this the case with both the G900A and the G870A. I'm in the market for either one since they are going for just of $200 new on Ebay. Are both phones now locked down of is the Active more problematic?
Both are locked down. AT&T and Samsung are being jerks to us and not even letting us have a developer phone to try to use like Verizon had.

If you are looking to root, then buy one that still has Android v4.4.2. They are available you just have to look for them. Don't put the SIM card in until you root or it will auto update and you can't go back.

Hi Sgt.CM,
I got my AT&T S5 on release day and never updated it. I have a SM-G900A with Android version 4.4.2! Is it possible for me to put CM13 with marshmallow 6.0.1 on there? I had assumed it was impossible...
Thanks,
Frozen

Nope can't because of locked bootloader. The best thing you could do is too root with towelroot and then flash safestrap and install a custom rom from there.

That is what I thought. What are the custom rom options? Is there a rooted marshmallow rom for the s5 i can install?
Also according to these articles it is possible:
http://rootmygalaxy.net/install-cm-13-rom-on-galaxy-s5/
http://androiding.how/download-galaxy-s5-cm13-rom-marshmallow/
I'm guessing they may not be correct?

amazon fire 7

Hello
I got an amazon tablet. The options in the device will be called 'Fire 7 (7th Generation). The system is Fire OS version 5.4.0.1 (13 August 2017). The back of the device is shown on the back: SR043KL.
I would like to change the language in it and get rid of built-in apps by installing cyanogenmod (or something similar). To do root I tried to use: kingroot, kingo android rot, oneclickroot and so on.
I also looked here in the forum but I can not really deal with it. Is there something you can do with this version of the system?
As of now anything 5.3.2.1 and later cannot be rooted, nor downgraded to a rootable version, sorry.

Amazon return period is 30 days; might be a good option.

Fire OS Downgrade Is Possible!

So, I looked on the Amazon website and I saw that true system software known as "5.4.0.1" wasn't available for download, so I assume we can officially downgrade from that version, no higher, only 5.4.0.0. Fire OS 5.5 probably won't work.

Obtain FireOS 5.4.0.0

Hi, does anyone have a link location to download FireOS 5.4.0.0 / FireOS 5.4.0.1 for Fire HD 10.1 (7th gen)? I'm currently updated to 5.6.0.0 and wanted to downgrade to FireOS 5.4.0.0.
I managed to snag a few 10.1 on the FireOS 5.4.0.0 and was able to use the Bloatware removal tool.
Thank you and much appreciated

Downgrading often bricks fire tablets (at least the 2017 models). I believe 5.6 in particular cannot be downgraded, and attempting it may break your tablet.

One must be cognizant of which models can be safely downgraded and to which builds. There are claims 7th and 8th gen models can be successful rolled back from 5.6.0.0 to 5.4.0.0 via 5.4.0.1. I have seen no similar claims for HD 10s.
As for firmware you will need to look elsewhere as this forum is for 5th/7th gen Fire 7 models only. The HD8/10 forum would be a good starting point.

thank you for the info. and sorry, didn't realize I was in the wrong forum.
will read up more there.
