Recovering from bootloop help - Sony Xperia XZ Premium Questions & Answers

Gday,
Ive been using my xz premium for about a year and recently it started retsrating randomly a couple of times but never caused me any issues, the other night i was on the phone and it was woring fine then 5 minutes later went to make a phonecall but on trying to unlock it, it restarted and now is stuck in a bootloop, it did get to the password screen once but i was unable to enter the correct password as i usually have a pin code and i restarted to see if i could select password reset or similar but of course it just went back to bootloop.
Now i understand that im in a pretty bad poaition to beable to recovwr data as i dont believe i ever rooted the phone. But also the two factor authentication app, without that i dont believe i can get into some websites to add the 2fa to anither device.
So my question is, is there any company that would beable to either fix the bootloop without data removal and i could get access to my 2fa and my data or at the very least someone who can recover the data from it ? Thanks dor any help you guus can offer.

If the phone's bootloader hasn't been unlocked you may be able to do a software repair using Sony Companion, but not sure as you're in a bootloop situation. If you have enabled developer options you can update the firmware using Sony's Emma without erasing user data. As for your 2fa app, install it on the next device and your info should come over when you log in on the new device

Thanks for the help Bob,
I have been able to get the phone to connect to sonys companion software but did not go ahead with the repair as it states that all data will be deleted, and thats what i have been reading online, is this correct ?
I think i may of enabled developer options, and i just downloaded the Emma software but am unable to login without my account been activated and cannot find access to the customization.ini file that looks like people use to use to get in without a login. Is there any way to get into the Emma software ?
appreciate the help.

Ok so i managed to get into the Emma software, however it said my phone has a locked boot loader, so i guess now the only option is if the sony companion tool can do a repair without erasing data ?

If Companion sees your device you can back up data and reinstall it after repair. I've never done this with Companion as my phones are unlocked and rooted. The few times I've tried to back up and restore (not with Companion) it never really restored the the way I thought it would. If your music and pics/vids are on the sd card, that stuff is safe. I usually just resign myself to setting up the phone and reinstall apps. But give back and restore on Companion a try. What kind of data are you worried about losing?

Dropping data and no calls/texts. Advice please.

Just in case this post gets moved, I want to identify my device as the Verizon Samsung Galaxy S3 (i535).
To give a little background on my issue, I have an issue with the device. When I first got it back in July, first thing I did was root the device. Naturally, since it was a new device, I was working with experimental methods... a couple weeks ago I thought to download CyanogenMod 10.1 (nightly build) to flash it with 4.2 and rid myself of the persistent OTA update that as we all know could not effectively install because of the measures I took to root. So, I boot into recovery and flash my custom rom. BAM! As it turns out, I did not have an unlocked bootloader and my phone was now teetering on the verge of being a $600 paperweight. I got that dumb yellow triangle saying unofficial firmware detected or some nonsense like that... Anyway, I look around the internet and decided that I was going to revert back to a stock rom using Odin, and then proceed to unlock my bootloader and root the device (I followed method 3 here) I used some touch recovery console that I have never heard of before (backups incompatible with ClockworkMod recovery) and something must have failed because my back up would not flash. I took the hit on losing most everything and reflashed successfully the custom rom mentioned earlier.
After about a week, I noticed the device began to drop data. 4G would just stop at random parts of the day, and I would have to disable and enable the data to get it to reconnect. At this point I was still able to make and receive phone calls and texts. After about 3 days of this, I concluded it was more than likely a bug in the custom rom, and that I could not live with it... so I redid the a fore mentioned tutorial and left the phone as a stock/unlocked/rooted device. The data issue continued, but with a twist. I was now unable to make or receive phone calls or texts. No matter what I did, I could not do anything and the 4G would only stay connected for a matter 5 minutes or so. When I logged into my vzw account, it identified my device as an unknown non-verizon device. Customer service walked me through various soft/hard reset techniques and nothing worked. They also suggested I try a new SIM card, which failed to work.
So, I turn to the bright minds of the android community. I have already decided not to invoke the Verizon warranty offered, where the result is they take my malfunctioning phone in flawless cosmetic condition and replace it with a "like-new" phone in working condition, because I think it's garbage that a warranty would give out used crap (should fix or replace). I have not contacted Samsung customer support yet because I wanted to see what my options were. I've already attempted flashing different radios and nothing seem to make any difference. If I have to, I will revert it back to stock again and invoke Samsung's warranty program, but I would much rather keep the phone. As it sits, I am stuck with my Motorola Droid Razr Maxx, and that just doesn't cut it.
So I ask, is there anything that can be done? Anyone know of a fix for my situation? I saw something about this in my quest for an answer and I don't know if my situation is a fit for this fix. If anyone has any knowledge of my issue and a work around for it, it would be greatly appreciated. I am at my whits end.
It sounds like you've done your homework on your problem.. The only thing in your post I didn't see was your sim card.. Maybe pulling it wait 2min restart. Shut down and insert,, or maybe a reprovision of the sim may be in order..
Ahaaaa....!!!
If your IMEI is intact, I would say to flash to ICS and reprovision the phone as suggested above. If it is not, you need to restore it with that backup that you made some time ago.
If it were me, I would reprovision, that is easy to do and I honestly think that it will work for you. If that works for you, reroot and restore your backup for TW ROM and you will be fine.

Well that's just it... I don't know anything about the IMEI and how to determine if that is the issue. If by reprovision you mean reflash back to stock, that is it's current state, and that did not resolve the issue.
As for the other comment in regards to the SIM card... I have already attempted that method, and it did not work. Also, a new SIM card was also tried, and had no success.

Google reprovision, it is a number combination that you enter on the keypad that resets your phone. I had a similar problem that you are having and that fixed our for me. You also need to know that when you do this, it will erase all of your information on the phone. It will be just like it was when you unpacked it and powered it on the first time.
You will have to be on ICS because they removed the option to do this with JB. Just search for the code to enter and you will be fine.

Ok. So I tried the reprovsioning mentioned above. When my phone rebooted I was on data and able to make phone calls. Score! However, I checked the IMEI and it said 0. So, thinking that it was just a matter of time before my device began to stop working again... I did the IMEI fix. Now my phone is placing calls and holding data without issue. The OTA updates are flooding in and installing without issues.
I would like to point out, while I feel better having done the combination of both reprovisioning and IMEI fix, ultimately the initial reprovisioning did appear to resolve the issue.
Thanks to everyone for the assistance provided.

OTA update Fail, Save my data

Hi ~
- Be kind with me, it's my first post! -
I'm facing a very bad problem with my Galaxy S6. A week ago I received an OTA from Samsung and I installed it. My phone rebooted and showed the bugdroid, meaning that the update was progressing. After that, the device keep rebooting over and over just after I entered my encryption password. I said to myself that I can try to wipe the cache because maybe an application was causing this problem. But now, the device is only showing the Samsung logo then just shut himself off.
Now I need your help to get my data. The hard part is that my device is encrypted. After many hour of search I see two solutions:
Flash the rom via ODIN
Install TWRP which can read encrypted volumes
The first solution seems easy and I keep the warranty. The problem is that I'm not 100% sure that flashing the rom again will not touch the /data and /sdext partitions (and the header/footer where master key are to decrypt the volume).
The second solution seems safer and should not touch any other partitions. But knox counter will be incremented and I will loose my warranty.
So, does anyone could test if flashing the rom via ODIN do not absolutely touch encrypted volumes and certificate that I will be able to get my data again?
Thank you a lot
Have a leap of faith. Go ahead and flash. Otherwise bring it to Samsung for warranty repair. They may be able to recover your data for you.

I want to be sure and I don't want to loose any photos if possible, so no
I already tried to go in a Samsung repair store (Allo PSM), but they just don't care about my data, their job is just to make the phone working again.
So Anyone is able to confirm to me that flashing stock Galaxy S6 ROM (AP Via Odin) doesn't touch the /data and /sdext partition that are encrypted?
After many hours of search, I was able to make my phone working again!
For anyone concerned by the problem in the future, here's some informations:
You can flash a stock rom, your encrypted /data will not be erased and you will be prompt to enter your password on the next boot
In my case flashing a newer rom didn't solve my problem (bootloop after entering the password of the encrypted partition). I had to flash the rom that was in the phone before the OTA.
Now everything seems to working again. No data were lost, all my configuration was saved. Android showed a message that a problem occurred during the upgrade process and I sent logs to Samsung, hoping that it will help them!

I messed up and now I'm stuck on FRP lock

Ok so admittedly I made a noob mistake and inadvertently unchecked OEM unlock and rebooted. So I'm stuck on FRP lock. From what I see, my only option is to flash the original firmware on the phone.
My question is simple: I don't have TWRP and can't do a NAND backup. Will my internal SD card get wiped as well? If so, is there ANY way I can back it up before hand??
Thanks...
Ok so I managed to save my arse after all, but I figured I would leave a reply here for archival purposes.
I used Odin to flash the stock Bootloader and PDA. Not only it didn't touch my SD, but it really didn't wipe anything and I only lost my root.
Two things happened I didn't see documented anywhere I looked: I got a weird crash on boot update and ended up in Stock recovery after auto reboot and got a slew of error messages, but a simple phone reboot worked.
Then I was asked for a password to restart, which turned out to be "default_password"...
Hope this will help someone down the road!
Sent from my SM-G930W8 using XDA-Developers mobile app
Cleaned & wiped all stuff, flashed stock 6.0.1 with Odin AP,BL,CP,CSC and same FRP google login shows up. Mind sharing those two files?
For sure, I just used the latest firmware on Sammobile: this is the generic one for Canada, but I'm on Rogers so I used this one.
I only used the BL and PDA, but I also made sure I wasn't locked out on my Samsung Account. FRP can be because of the custom binaries, but it can also be a system lock out and I've read that in some cases it's because the phone has soft locked itself out. Not sure how accurate that is, but wouldn't hurt to check I guess...
now all ok or still facing same?

Possible to bypass/change pin/pattern AT restart?

Hello, I hope it's the right part of XDA to post my thread as I have serious issues here.
Got my HTC 10 (with Android 6)back from repair today and restored my backup.
But dumb me it seems as if i set a password/patern whatever and i can't remember it.
So after a restart i can't unlock my phone cause it's asking for the code (and won't let unlock only with fingerprint) and i can't remember.
All combination that i would have used are wrong and now i got a working phone back again (after almost 2 month of repairing) and can't unlock it.
Is there any way of bypassing/ignoring the restart password or is it possible to only unlock it again with the fingerprint that is stored?
As i don't know what i should do if i don't get my phone unlocked
I tried to factory reset it andxthat worked but all my apps and data is gone as google seems to only restore some apps and almost no data of the apps.
So i set it up as a new device and only restored /data but immediately after reboot I was asked to put in the forgotten password.
So is there anyway of bypassing the pin/pattern after restart and only unlock the device with the fingerprint that is stored. And if not, is there any way of being able to use my /data after a factory reset again?
Kind regards

SMG386T1 Partition Recovery

Hi, I've been meaning to write this since 2016 or 2017, I think, butI think I can still remember all the important details of this crisis...
So I had rooted this 'Galaxy Avant' phone originally so I could disable/remove the extra stuff of the systems' in the hopes of improving the phones' performance, but I didn't change the OS from whag metropcs gave me at that time. I also had a password and/or a pin lock on both the sd card, startup, and internal memory. Everything was okay until I ran into a wifi issue where it wasn't connecting to a semi-public wifi hotspot, so I thought if I cleared the wifi apps' cache the issue would go away. Trouble was I didn't know that the wifi cache wasfor some reasin the same as the system's cache, and a few seconds after clearing it, my phone crashed, and continued to restart itself. So I panicked and tried removing the password/pin locks for easier backup to recovery/resetting. Well the external sdcard managed to decrypt, but when I proceeded to attempt the same for the device, it decided to factory reset itself.
I lost nearly everything from that event. I did periodic backups to the sd card but not daily and since that phone was also responsible for my own memory retention, at least a month or two of my soul is still missing. Any new contact, commitment, itinerary, life decision, goal, deadline, or other important note from that time was wiped and can't be found anywhere else, and I still don't know who else is or was affected from this (especially if I had just made their acquaitance).
So all that to say I must get this device back to how it was before the cache-wiping incident. The phone hasn't been turned on since, except to dump the system image onto my linux desktop. With testdisk I can see what I assume are the deleted partitions from before the factory reset, but I don't know how to undelete+decrypt them and/or copy them back to the device. Please tell me honestly that there's a way to do this, and what that way is. My functioning really depends on it...

Go to Sammobile .com or samsung-updates .com, enter your model number in their search feature to find your stock firmware. If you can find the firmware, you can use Odin to flash the firmware to restore the device to normal function.

Thanks, but the device already functions normally; it reset itself to factory defaults, after all.
I just want to be able to restore the device to as it was before the accidental cache wipe—apps as they were, files, and all...

Oh, you mean you want to recover your lost data. All I can say is try some data recovery software on PC, there isn't any guarantee that it will work though. Data recovery on android is not very reliable.
