My tablet just jumped from 5.3.2.1 to 5.3.3.0 in one day. I tried kingroot several times hoping it would work. It did not. I performed factory reset on it and signed into amazon. When i woke up it was at 5.4.0.0. My question is if a root exploit is found for 5.3.2.1 or 5.3.3.0 can it be rolled back? This all started from a bad SD card that kept resetting my old fire. I thought there was something wrong with the tablet and bought a used one off eBay hoping it would come with 5.1.2. I love AOSP on these machines.
[Fire Q&A, Help & Troubleshooting] DragonFire1024:
If I recall correctly, 5.3.3.0 COULD be rolled back to 5.3.2.1. And 5.4 supposedly, or theoretically can be rolled back to 5.3.3. So theoretically, yes it could be rolled back to 5.3.2.1 from 5.4.

Hello guys. I really appreciate what is done on this forum. Keep on doing it, it really helps a lot of people out there. I would like an explanation on how to roll back from OS 5.3.3.0 to OS 5.3.2.1 on Amazon fire 7" 5th gen. Thanks

Just for heck it i adb sideloaded 5.3.2.1 while on 5.4.0.0 just to see what happened and it appears to have downgraded just fine. I know there was nothing to be gained from this but I needed to know. This tablet is to be kept off of wifi

Hey, do you have a link (or tips) to how you did this? I have 5.4.0.0 and the advice I'm getting is that this system version cannot be rooted or downgraded, that trying will brick it. You're the only one who seems to have had success. The follow-up link given by someone else (https://xdaforums.com/ama...h-gen-t3285294) doesn't have a shred of info on 5.4.x.x.
[Fire Q&A, Help & Troubleshooting] daniel3016:
I just downgraded to 5.3.2.1 from 5.4.0.0 i have never acheived root. You gain nothing by doing it. I did it just to see if i could. Hope that helps.
[Fire Q&A, Help & Troubleshooting] DB126:
Clarification: you can not downgrade from 5.4.x.x+ to a rootable version of FireOS as of the date of this post (5.3.1.0/5.3.2.0 are the highest rootable builds). Amazon updated the bootloader concurrent with delivery of FireOS 5.3.2.1; manually rolling back to a lower version will brick the device. At present there is not a method for downgrading FireOS independent of the bootloader on an unrooted device.
[Fire Q&A, Help & Troubleshooting] savvytechwinner:
To Clarify - Can I downgrade 5.4.4 to 5.3.2.1 Safely?
[Fire Q&A, Help & Troubleshooting] DB126:
Probably 'yes' based on a couple user reports. However, there is no benefit to offset the potential brick risk if the version of FireOS currently on your device has an incompatible bootloader. 5.3.2.1 can not be rooted so what's the point?
[Fire Q&A, Help & Troubleshooting] savvytechwinner:
I downgraded. I had the system updates uninstalled so have no clue if it worked but I downgraded anyways because root might be found in a different method and got patched? have no clue and no suspecting it. Just proving that dowgrading is safe from 5.4 to 5.3.2.1
[Fire Q&A, Help & Troubleshooting] ormaoz:
savvytechwinner, Can you please link to the tutorial you followed in order to downgrade?
[Fire Q&A, Help & Troubleshooting] DragonFire1024:
I believe you can find the 5.3.2.1 software here. I believe all you have to do is place the .bin into the internal storage (SDcard) and boot into recovery to flash it. I'm not 100% certain though.
[Fire Q&A, Help & Troubleshooting] savvytechwinner:
You download the 5.3.2.1.bin file from rootjunkysdl.com and adb sideload it
[Fire Q&A, Help & Troubleshooting] DB126:
...or from the forum index which contains a ton of information and resources that most choose to ignore.

Hi can i rollback from 5.4.0.1 to 5.3.2.1 ? or to 5.4.0.0 !?

[Fire Q&A, Help & Troubleshooting] geordie1882:
Any news in the community about a 5.6.0.0 rollback?
[Fire Q&A, Help & Troubleshooting] TheBigEasy88:
Please do not take this the wrong way but this question has been asked too many times to count. The number of 'topics', created in this sub-forum, are nowhere close to that of other devices (Galaxy S8+, OnePlus 5T, etc.) so searching for the answer to your question should have been a piece of cake.

With that being said, no. I would block all OTA's moving forward, in hopes of a miracle, but the chances of that are slim to none. I'd suggest buying a tab w/ an unlocked BL, if you enjoy the tweaking aspect, or just roll with your Fire and enjoy it for what it is.
[Fire Q&A, Help & Troubleshooting] steve8x8:
I didn't have the time and resources to perform a detailed comparison of 5.6 and 5.4 for the two Fire 7 generations - but the bootloader files are different enough to suggest that an attempted rollback would result in an (unrecoverable) brick.
[Fire Q&A, Help & Troubleshooting] DB126:
There have been several reports of successful 5.6.0.0->5.4.0.0 (via 5.4.0.1) rollbacks on both 5th and 7th gen Fire 7" devices...along with a couple reported bricks. It is hard to know what happened with the failures as few details were offered. It seems apparent 6th and 7th gen HD 8 models can not be rolled back as every reported attempt has yielded an unrecoverable brick.

FireOS 5.6.0.1 is now in the wild which adds yet another variable. History suggests small upticks in revision level should not be taken lightly. 5.3.2.0 could be rolled back and rooted; 5.3.2.1 can not. Several individuals learned that the hard way.
[Fire Q&A, Help & Troubleshooting] Bad Bimr:
I bought a 3-pack of Fire HD 8 (2017). Two units came with 5.4.0.0 and one unit with 5.4.0.1. I used the tools found here on XDA to stop OTA and debloat the TWO tablets but can't with the 3rd. How did you get your to rollback from 5.4.0.1?

Thanks

[Sony Xperia XZ Premium Guides, News, & Discussion] lancewicz:
Hi Guys,

I'm almost happy user of XPZ. I bought non-branded version G1842 dual. I want to use VoLTE(and WiFiCalling if possible) on my handset. My operator Orange PL supporting VoLTE but only on Iphones and branded firmwares for Android phones.

Sony support/service refuse to flash my phone with Orange firmware - so I would need to do this alone but official Orange firmware is available only for single sim XPZ G8141.

Question - can I seftly flash G8142 with G8141 firmware? Or do you know that maybe VoLTE operator configuration is kept in one of sin files like modem_X-FLASH-ALL-42E5.sin and I could just swap one file in whole firmware folder?

Secondly VoLTE - I send email to operator and they replay that configuration of VoLTE is many settings/parameters inside firmware. Besides *#*#4636#*#* option VoLTE provisioning I didn't see any configuration for this service. The config is so deeply inside firmware? When I switch ON this option in that menu it's not saved and when I enter once again the menu is one again switched off.

What I saw most of the VoLTE arround globe have problem - that they need to use branded firmware. Do you think in the future it would change? As far as I check for Iphone it works on all - it's relevant it's branded or non-branded phone.

best regards,

Piotr
[Sony Xperia XZ Premium Guides, News, & Discussion] slaskbak:
I'm in Sweden and VoLTE got enabled for me when I switched carrier. I didn't do anything but switch SIM. I had a Z5 Premium at the time and now I'm on a XZ Premium and VoLTE is enabled as default.

And standard Nordic Combined firmware, no carrier lock.
[Sony Xperia XZ Premium Guides, News, & Discussion] VeixES:
Piotr, i think with DS version of device you are out of luck. There is no european provider specific modem configuration(required for volte) available for the dual sim device. I have attached available configurations in the zip file.

To get single sim modem configuration files flashed to device, you need to flash system.sin, but i STRONGLY DO NOT recommend doing that. Potential brick on your way.

Mixing flashing the single sim and dual sim different .sin files is highly experimental.

If you really want VoLTE then i think less headache is if you can find a person who is willing to switch single sim version with you.

You can get any region G8141 and then flash https://xpericheck.com/cda/1308-7002

Phone needs load configuration amss_fsg_maple_orange_poland_volte_vowifi_tar.mbn to get VoLTE and VoWIFI.

Checking current oem.sin file, i can see that when inserting Orange PL sim, then amss_fsg_maple_orange_poland_ims_tar.mbn is actually loaded.

Is the XZ Premium on confirmed VoLTE devices list on Orange Poland webpage?
[Sony Xperia XZ Premium Guides, News, & Discussion] rafi.mv6:
Hello, any news in this thread? I have the same situation but with XZ1. I have nonbranding dual sim working on T-Mobile PL. They sell XZ1 only single sim, so there is only single SIM firmware from T-Mobile. Someone test flashing single SIM firmware for dual SIM XZ/XZ1 Xperia?
[Sony Xperia XZ Premium Guides, News, & Discussion] VeixES:
Should be same situation as with xz premium. flash single sim fw via newflasher and you are done. will lose 2nd sim but otherwise should be good.

Please Read different topics to know how other users have done it to xz premium dual sim.

Great! Dualism is sold cheaper than singlesim
[Sony Xperia XZ Premium Guides, News, & Discussion] lancewicz:
Why dual sim are sold cheaper then singlesim? Which country?

I bought XZP in presale and price for non-brand and brand at telcos was the same. For me I was thinking it's benefit because I get dual sim and "clean" FW.

I suppose that Sony (and also Samsung) don't care about this....I hope that carrier services app in android recently added by Google would be the way to update settings for operators for all headsets. Like apple does. That would solve that configuration....

Only when small file missing and and lot of issues with VoLTE and VoWiFi.
[Sony Xperia XZ Premium Guides, News, & Discussion] lancewicz:
Maybe single and dual sim are exactly the same HW? and when you load DS FW into SS version you will get DS? anyway 2sim share slot with SD ...maybe Sony simply manufacturing process?
[Sony Xperia XZ Premium Guides, News, & Discussion] lancewicz:
To confirm files like amss_fsg_maple_orange_poland_volte_vowifi_tar.mbn are kept in which file? oem_X-FLASH-ALL-42E5.sin or modem_X-FLASH-ALL-42E5.sin ?

This file are modem configuration so it should be more in modem.sin but you mention that you check oem.sin for that maple config?

Is 100% configuration of VoLTE are kept in amss_fsg_maple_orange_poland_volte_vowifi_tar.mbn ?

In 20 minutes I would also try to flash XZP like rav.6 with XZ1 to check that solution. And let all know.

br,

Piotr
[Sony Xperia XZ Premium Guides, News, & Discussion] VeixES:
oem.sin only includes instructions which configuration(.mbn) to load.

all configuration are universally available in system.sin
[Sony Xperia XZ Premium Guides, News, & Discussion] lancewicz:
I can confirm. Solution by rav.6 is working also on XZP with Orange firmware Poland.

I see now options for VoLTE and VoWiFi and VoLTE are enable but not working:(

I don't know why:(
[Sony Xperia XZ Premium Guides, News, & Discussion] rafi.mv6:
In T-Mobile I have activated VoLTE and VoWIFI by sending message to T-Mobile. I don't know how it looks in Orange, but i think you must activate it first.

I've edited the modem.conf(in /OEM/modem-config/) file for my X performance and changed it to the name of my operator but I have not noticed any changes in volte. Is this how I change it or do I need to reload something? Is there a way to get the software information ( like the screenshot posted earlier) and find out whether just doing that changed my modem?

UPDATE: Checked the software info and it's still on the old modem despite changing the modem.conf file. Is there a way to force it to change without the customisation selector (modem switcher) tool that people have managed to get working on the Z5?

UPDATE 2: reflashed phone via Flashtool and excluded oem partition from being flashed and now have working VoLTE

Went to recovery, tried wiping cache, after about an hour I thought it was just frozen and not doing anything, so I restarted the phone, then went back into recovery and factory reset. Now the M logo appears for a few seconds, then disappears, but the screen buttons are unresponsive. At this point, the only thing I can do is hold the power button and the M screen will come back up, OR I can get into fastboot and everything acts normal until I try rebooting. I've wiped cache and factory reset several more times and the same problem keeps persisting.

Any tips?

Thanx
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
It's entirely possible you are having some kind of hardware failure, but as we can't help you fix that let's focus on software for now.

Is your bootloader unlocked and do you have TWRP recovery? If you have TWRP, have you tried to restore any backups of your system?

Have you tried reflashing firmware, either lastest stock via ADB or custom ROM? (choice depending on whether your bootloader is unlocked or not)
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] VooDooCC:
bootloader is locked, everything is stock.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
do you have TWRP installed? If so, do you have a backup you can restore?

If not, then reflash latest firmware (either via TWRP or via ADB).
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] VooDooCC:
TWRP is not installed. Is there a guide somewhere how to reflash? Everything I have found is for a normally working phone.

[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
whoa, I somehow mis-read this. Your bootloader is locked? Do you want to unlock your bootloader? If so, if you do not have the latest firmware, then don't flash the latest firmware. Ignore my last post.

However, if you are already on the latest firmware, then you can't unlock your bootloader anyway, so you might as well re-flash that firmware to fix whatever is corrupted.

---------- Post added at 02:56 PM ---------- Previous post was at 02:54 PM ----------

I read too fast also. I thought your bootloader was UNlocked and you were still stock.

What firmware were you on before you had this trouble?

If you were on the very latest already, then you can't flash that firmware in that thread -- because you can't downgrade with a locked bootloader. You can only flash same version or higher.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] VooDooCC:
I assume I was on the latest, at least I know I didn't have any pending OTA's

Sorry for being a bit ignorant on this, I told myself with this one I was just going to leave everything alone and not unlock or do anything like I did on all my others.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
OK, let's assume you were on the latest already.

With these instructions below, on step 4 instead of the link he provides you would use the link I provided (which is the very latest firmware). [MENTION=5901115]TheSt33v[/MENTION]'s goal for this thread is to unlock the bootloader -- and these instructions were originally intended to get users with older firmware to upgrade and install the very last version firmware that could be unlocked with Sunshine. We are re-purposing the instructions to get you to re-flash the latest firmware on your phone, hoping that will fix any corruption issue.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] VooDooCC:
The blue link you provided in that post doesn't work. Assuming it's the same that you provided a few posts earlier, there is no flashall.bat file.
