OTA Update, Now Secure Startup PIN not working, please help! - Samsung Galaxy S7 Edge Questions and Answers

I just got an OTA update for Nougat (BTU) on my S7 edge.
68MB, small update, so I let it install
I've had Secure Startup enabled on my device all along, never had an issue, but after this latest update had finished installing, device rebooted, asking for my device pin as usual, but it will not accept my PIN! I've been very very very careful in entering the 4 digit device pin correctly, but it just won't verify! Please help, I'm desperate, have 4 attempts left before it resets the device!
My last reboot was about 2 or 3 days ago, same pin worked, but broken after the OTA update.. I don't want to factory reset if I can help it, haven't done a Smart Switch backup in about 2 months, so my app data will be well out of date if I do

So I eventually gave in and did a factory reset (no choice)
Samsung Cloud FTW - restored my apps, home screen settings (even folders and shortcuts) from the nightly cloud backup! All I missed was this morning's WhatsApp texts (also nightly backup to Google Drive - WhatsApp detected that backup without any prompting, awesome!)
So all that I lost in the end was a good chunk of my day (letting nearly 200 apps reinstall is a slow process, and then anything with TFA needed to be re-logged-in, and my code gen app for TFA reconfigured, but overall it was pretty painless, all considering!

Is anyone else having this issue?
What I read from the stock FW thread, if a firmware is flashed using odin (not OTA) there are a lot of comments to have Secure PIN enabled because a PIN is required afterwards?!
So what to do when updating with OTA? pin enable? disable?

Is there a way to force another Software Update?

Tuesday
306sh activated with MVNO, SA300 firmware, rooted, with TWRP recovery,
working fine for past 2 months.
For unknown reasons, it decided last friday (at home, none to low signal) to do a system update
(from SA300 to S7232). Phone - on the desk- just "dinged" and msg came up "updating
system software". I attempted to cancel, but it didn't respond. Less than a minute later, "Update Successful" msg. Didn't reboot, anything, settings showed S7232 firmware. (SA300 before,
i had done my weekly backup earlier that morning).
Since then, phone constantly reboots at the "Aquos" screen; after an average 8 hours of rebooting, it will boot to setup, the talking setup screen. Works perfect for about an hour then rebooting starts again. Let battery die last nite, tried again this am - same thing rebooting.
TWRP backups don't fix problem- weekly backup, i have 6 i've tried, factory reset doesn't fix, if i try to Software Update, it checks, tells me, "up to date".
I turn on wi-fi to use the phone from home, , guessing it did a ? hit & miss ? ota update since the
wi-fi was off when it attempted the update. Home is a very minimal signal area.
Any way to force it to take the S7232 update again?
(I could update over wi-fi if i had wanted, only i didn't want the update anyhow).
thanks, rik
I can give you a link for a backup with latest firmware, you will have to wipe data tho

This is a full backup from newest firmware but you need to wipe data before boot

Stick firmware updates are not compatible with custom recoveries

Just home, thanks
Hi,
Thanks for the help, just home from work (rough), so i will plug the
Aquos in tonite and hopefully be able to try the file tomorrow,
(that 8 hour boot thing), just downloaded your file, i'm ready.
This is my take-to-work personal phone, sprint zone, and i missed it today.
Your help is really appreciated.
rik
Final note
thought i'd just post to let you know the phone obviously had big problems
-- it failed to start today -- just buzz on buzz off -- even after 4 hours charging,
all i could get was the battery dead screen, wouldn't come on at all.
Guess the real problem was with hardware, i laid it away in the junk phone box
in the attic, end of Aquos Crystal.

Question: My 306SH would not update (still at S8216). Could use your back up to update my firmaware?
After 306SH ph was acting weird, did a hard reset & saw system Software updtd to S7232, & unk file in Misc (.eCtcQjbu1dgnvtFnvnr6yepTp1M=) I then installed Malwarebytes & scan detects this S7232 software update as malicious malware Android/PUP.RiskyTool.Agent.ay (dm.redbend) "/system/priv-app/fotaClient.apk". When going to System to do an manual update, Malwarebytes popups w/same msg every scan "Software App", even aft reboot 2days ago 7/12/2017. And phone wont let me create new google acct. An error that "google account mgr not working" popup & I see that same unk file reappears. Ph not rooted -XDA says "there's no root for 306SH that works">see XDA blog 'Root for Aquos Crystal 306SH ONLY'.
Go to the Sharp USA website for the 306SH firmware, and see what firmware you are on.
Download the firmware from the versions higher than yours, and if there is a repeat, notably "kernel.img", download the most latest version of it.
Then, plug your device into your computer, make sure you have the proper drivers installed for the Sharp Aquos Crystal installed on your computer. Boot your device into bootloader. Go to a terminal, cd to the directory where you downloaded your .img's from the website, and do
fastboot flash kernel kernel.img
Ex.
fastboot flash foo foo.img
And you can flash all the latest updates. When done, exit the terminal, make sure the device is unmounted, unplug from computer, and reboot your Crystal.
Hooray, it should be updated!

Turkbot, I hate to beg on my first XDA post, but is there any chance that you still have that ROM and is there any chhance that it's not TextNow loaded? I've got TWRP, Busybox, SuperSU, Xposed, and I've tried every which way to edit the prop, tweak it with modules, unlock etc (it even works with my Sprint MSL, but crashes when I try to manually set my MDN and MSID) It just says no SIM/no service and refused to give me any signal except for GPS and WIFI without one. Countless 'techs' over the phone and 3 different Sprint repair stores claim they don't have the stock firmware and Sharp actually claims that the reason they can't help me with the firmware is their contract with Sprint forbids it.. If you still have the file or a TWRP / Titanium etc backup you would be my savior.

Decrypting loop after OTA update

Hello fellow people of XDA!
Today I got an OTA update for my S7 edge (SM-G935F). The update has installed fairly fast (after the first reboot). But then, it got stuck on a decrypting loop. I have enabled prior the full phone encryption, and set it to ask for a password at each start. I entered the password correctly, as it said Starting Android... after, and since then, only the rotating padlock is showing. Every like 5 minutes the soft buttons are lighting up for a second, but then nothing is happening. After a while it even gets hot, but still nothing. I had this issue at the previous update too, but it started after like 30-40 minutes. Now 90 minutes have passed and still nothing.
I can reboot to the recovery and bootloader screens, and everything is fine. Knox not tripped, not rooted, everything official. In the recovery screen it says that my CSC is ECT (but according to sammobile it should be CNX).
Some additional info: samsung/hero2ltexx/hero2lte
7.0/NRD90M/G935FXXU2DRAG
I will try to flash a stock rom (PDA: G935FXXS2DRAA, CSC: G935FROM1DQJ3). If that doesn't work, I'll flash today's rom (PDA: same, CSC: G935FVFG1DQI1).
Any tips/help would be greately appreciated! Would not want to fall to the wipe data method, because I don't want to lose everything... But then again, I guess that would remove the boot password...
Thanks!
Update: After waiting for like 10+ hours, nothing has changed. Maybe I shouldn't have forced a reboot after an hour of the ota update? Going to try flashing the firmware now.
Update 2: I flashed the firmware, now the buttons seem to light up less often. But after an hour of decrypting, I guess the ultimate soultion would be to do a factory reset, since no one is helping...

Then use that same password, i think there is confusion, there is a password when you enable fingerprint and then a password when you enable secure startup. Be sure not to confuse them. If it still happens, then I guess there's got something wrong with the update, and only way is a factory reset. Btw, i also updated and i normally entered secure boot password and it started okay. Don't know what caused this for you.

I entered the password correctly, as it stated "Starting Android..." then the rotating padlock took forever. More than 10 hours even. But in the end, a factory reset helped me. But rip my photos and memories...
Don't use device encryption anymore and leave OEM unlocking enabled in developer options.
Those two settings cause more hassle if you want to keep data, and make backups from time to time using Samsung Smart switch on computer. Use a microSD card to store and take all your photos from camera.

Right, but i use encryption and i could update without any problem, don't know what caused this issue with him. But one should backup all data BEFORE updating, as i did to save yourself from such hassle.

Yeah, it's a sure thing I won't turn on Secure Stratup anymore. I don't know what OEM unlock does or does not, but right now, I don't have dev options enabled. If I had a microSD then I couldn't care less about resetting my phone, but since I don't have, because I have two SIM cards and a memory card has no place left, I feel bad.
Still, I don't know caused this issue. I had OTA updates before with full device encryption enabled and I had no issues before. I kinda used the same disk space at every OTA, so it should have took the same time... And I have to mention, that I did not tamper with the software. No root, no custom rom, and software only from the play store.
To enable developer options you click Build number 7 times which is located in the Software information tab in settings.
OEM unlock allows you to flash and boot the phone with custom binaries (Custom Recovery, Kernels, Roms). You can leave OEM unlock disabled if you don't want people that may steal your phone and use it for themselves.
With OEM unlock disabled and a google account signed in, it will block anyone from using the phone after a factory reset on stock Samsung firmware as it will prompt the user to enter the google account that was associated with that device.
Unfortunately there are rare cases that a OTA update may fail. Reflashing correct stock firmware usually fixes it but in worse case scenarios a factory reset will be required.

Never had OEM unlock enabled, because I didn't know what is does, so thanks for the info. I reflashed the correct stock firmware, but that didn't help either, so I had to resort to wiping the data... Regarding this, do you know by any chance a good software for recovering data without root?
I don't know of any unfortunately, if anyone has any good paid ones that actually work please post here.

Rooted S7 Edge Lost Mobile Carrier settings

Hi,
I've recently rooted my s7 edge (SM-G935F) and all seemed to go quite well until I uninstalled xposed and my phone went into an FRT lock. This was probably due to a wipe I did while rooting after which I forgot to enable OEM changes. To fix this I flashed firmware using Odin to this one G935FXXU1DQL8
Only updating PA, after which the lock was removed but I only had a samsung logo which I was unable to progress from. I waited until the battery run out (could not shut the phone down) and then booted into recovery mode and did a factory reset. The phone came back to life, but was weird.
Apart from loosing all of my app data (logins etc) the keyboard was wonky. It lagged and the predictive text would work in passwords, essentially eating every letter as I pressed it. The spellcheck wasn't working even tho it was selected. The keyboard would also lag, often taking 5 or more seconds to respond at first after which it worked fine but this only occurred during logging into an account, and the shift key never worked properly, and required holding down to capitalize as the one tap to do the first letter didn't work.
I didn't think too much of it and went back to trying to get myself sorted with xposed. The moment I flashed TRWP again, suddenly my internal storage disappeared. The phone no longer saw it and no matter what I did it was totally dead. I had to change the file system and remount in order for it to come back.
When I came back I flashed PA, SCS and CP and since then my phone has lost the ability to recognize a telephone carrier. Mobile networks is plainly missing from the options, and I do not get any bars, just a circle with a line through it. I have since then tried other firmware from sammobile such as G935FXXS1DRA5
And used samfirm to download the newerst one directly from Samsung all of which result in the same problem - No telephone carrier options, phone cannot make calls and I can't do anything about it.
Can anyone help in bringing them back? What did I do wrong? Thanks in advance.

**FIX** BL Flashed through RMM State Prenormal (OEM Locked) - IMEI/BASEBAND RESTORE

Excellent news and a solution i havent found anywhere else yet!
Follow up from - https://forum.xda-developers.com/galaxy-s8/help/restore-imei-attempt-stock-rom-flash-t3802527
TL;DR attempted to re-root as soon as the bootloader unlocked. It all seemed to stick again, and got the big red message of doom again.
"Official Binaries Only" - Last time i was able to restore to at least switch on the phone to run down the rmm state timer to zero to flash again.
Tried the several methods of flashing through a locked bootloader (old BL file, quickly restart download mode and spam start on odin, etc) - literally nothing would allow me to flash anything that included the BL file. IMEI and baseband remained unknown. Phone went in drawer for a few days.
Just went and downloaded the latest XSA (Australia, Unbranded) build - https://www.sammobile.com/firmwares/galaxy-s8/SM-G950F/XSA/ and guess what boys and girls?
This sucker flashes straight away with Odin 3.13.1
It has completely restored my IMEI and baseband, i now have full Cell connectivity again, and its all back and working again. OEM unlock is still disabled, Samsung Pay still locked out which is fine, but otherwise, i have gone from brick to fully working Exynos S8 again.
TL;DR IF YOU HAVE ISSUES WITH A BRICKED PHONE BECAUSE IT WONT LET YOU FLASH ANY STOCK ROMS TRY THAT ONE.
Thanks for the replies to my other threads trying to help out with this. Much appreciated.
Peace out.
For heads up for other after this, how to get OEM unlock to pop up again.
Go-to date and time, change the date to 8 days prior, disable automatic update of time.
Reboot phone and it may take a few tries, but OEM unlock should pop up again in developer settings.
Just went through all this without any help and it sucked lol. Thanks for making this thread for everyone.

I havent been inside since i replied to you before. Gave up trying to fix that and was doing other things. Just reset both the s8 and s8+ to look at download mode... noticed the rmm flag was GONE rebooted and sure enough OEM Unlock is done.
You genius.
So - Anyone actuallly reading this -
Lost root, reflashed and cant install TWRP etc, "OFFICIAL BINARIES ONLY" crash, cant replace bootloader, missing IMEI/Unknown baseband -
TRY FLASHING XXU2CRED stock rom from 18/6/18 or later. This will flash despite a locked bootloader.
Once up and running set up the phone for use. Reboot as normal. Then turn off automatic time and date set date to 8 days prior, reset phone a couple of times. Get annoyed because you keep having to reset the date backwards. Reboot phone again and set automatic tin me and date again. Reboot. Bamf unlocked and completely restored SN-G950F.

Ah I should have also mentioned I also did the same, flashed the same firmware when I was desperate and after some bit I also noticed prenormal change to official in download mode (the tell tale). I had OEM unlock on always, just was stuck in prenormal mode and couldn't flash anything.
To speed up the OEM unlock trial and error process do this as well:
1. After setting time/date back 8 days (and auto update time off). Go-to updates in settings, select manual update and check the server (it will error probably but that sets a check on their server to allow the RMM state to change next time it's connected properly).
2. Do this quite a few times, with reboot and constantly fighting the date auto update.
3. Flash the CRED firmware mentioned, boot it and setup once. Then reboot and go-to download mode.
4. You should see official as the RMM state now and you can happily OEM and flash away!

Have just flashed TWRP, used the Comsy version to be safe (3.13.1 fine for the stock rom flash) - I used comsy as it is mentioned in hte post OREO S8 update. It allows TWRP to be flashed but maybe thats whats breaking everything else. Ill try magisk next.
Fire up TWRP and enable system changes. FIRST - Advanced wipe and format system (Im 99% sure this is what screwed my last couple of roots), hit yes and do it. Reboot into recovery again.
Flash no-verity, then SuperSU (or your preferred root, i use Aroma installer first, THEN you have to flash the SuperSU binary with that)
Wipe dalvik etc. Reboot into system. As i type this its now in the 'Welcome' screen. Gimme a minute and ill check all is good.
UPDATE - Everything restored installed titanium backup root held. Rebooted phone aaaaaaaaand - "Only official released binaries are allowed to be flashed" - Back to square one. Will attempt same reflash now, but the root procedure kills everything. Back in download mode again. RMM State: Prenormal returned.
It is now succesfully flashing the stock rom in Odin 3.13.1 - Accidentally started it with Comsy and it DID NOT WORK. You MUST use the normal version to flash the rom im using.
Looks like we def have a stable way to refire up the phone again, and get around RMM state prenormal nice and quickly, so ill go ahead now and try and find whats going on with things breaking afterwards!
Thanks again guys.
Did nearly the same as you, dejavu.
I use magisk though. Be sure to flash a rom or kernel with RMM state fixed lol, or you'll be back here soon.

Someone should clean this up and get it stickied.
I imagine there are alot of users here with this same issue, after the CRED update we can't downgrade our bootloader, and in a panic you can get stuck here.

Looks like that wont be an issue any more to be honest this phone is now a backup thankfully so i can play around with it to my little hearts desire.
Im about to try the magisk install. SuperSU/Aroma definately breaking something somewhere. Or verity. I dont know but rooting the phone at the moment is killing it again.
Also, i have NOT lost IMEI or baseband this time. At the very least for Australian SN-G950F phones, this is a 100% flashable stock rom regardless of your RMM or phone status. I cannot say this for any other model in any other country on any other carrier, but this is all working for a carrier free Exynos S8.
Maybe y'all better archive the actual stock somewhere before someone realises theyve made a mistake somewhere and it gets pulled. Im definantly backing it up.
I just got that oem unlock trick to happen in 2 shutdown/restarts NOT reboots. BUT. I did NOT enable developer mode until i had disabled automatic time updates and turned the date back 8 days. The option came up instantly. Is something comparing a hardware clock deep in the system to a software clock in the os to and developer mode comparing something in between? Either way, on to reflash TWRP again now. This is a good day.

Hokay so - From a factory refresh, to the OEM unlock trick -
Flashing TWRP with 3.13.1 and allowing the phone to reboot - Phone will reboot as normal, TWRP doesnt stick. Shutdown and reboot into recovery gives you stock recovery.
Flashing but ensuring phone reboots directly into recovery gives you TWRP. A format data and reboot directly into twrp again lets me install no-verity.
- AFTER DOING THIS I AM GETTING THE RED LINE OF DEATH - Something in the system isnt letting the modifications stick.
Reflashing with the Home_CSC still seems to work as normal and i havent had to go through the welcome stuff this time...

Have you found and used this after getting your phone setup right (w/twrp)?
I think you should flash magisk, then this after.
After I had this "panic" I flashed the custom rom I was aiming for (once RMM: Official). That rom has a kernel with the RMM state fixed/locked.
Maybe look for a custom kernel if you want root, I believe this is the fight we have to put up even on stock w/root.
Download the Australian stock rom and install it but do not recover IMEI or coverage. I think it's because my G950F (singlesim) cell phone thinks it's G950FD (double sim). This causes the cell phone to get confused and not recognize any imei or sim. Does anyone know how to fix it?

Do we need to factory rest or just reboot phone after we change date?

Sunuva....
I havent been inside since i replied to you before. Gave up trying to fix that and was doing other things. Just reset both the s8 and s8+ to look at download mode... noticed the rmm flag was GONE rebooted and sure enough OEM Unlock is done.
You genius.
So - Anyone actuallly reading this -
Lost root, reflashed and cant install TWRP etc, "OFFICIAL BINARIES ONLY" crash, cant replace bootloader, missing IMEI/Unknown baseband -
TRY FLASHING XXU2CRED stock rom from 18/6/18 or later. This will flash despite a locked bootloader.
Once up and running set up the phone for use. Reboot as normal. Then turn off automatic time and date set date to 8 days prior, reset phone a couple of times. Get annoyed because you keep having to reset the date backwards. Reboot phone again and set automatic tin me and date again. Reboot. Bamf unlocked and completely restored SN-G950F.

Can you please help me? so when you say reset phone you are talking about restarting it? I have tried this a few times and not working for me. My oem has always been unlocked, but still have prenormal

I was stuck here too, flash the latest CRED firmware he linked.
Then boot it one time (setup til you see launcher).
Do the OEM unlock method.
You can follow the steps after if you want root.
I suggest magisk and a custom ROM, that had RMM state fixed (so you won't get locked again).
Good luck!

Sorry i missed your reply i hope you got it fixed if not post again and ill see if i can help. Ive definantly gotten that oem unlock trick working which is awesome but its fiddly. I dont think it works if you turn on flight mode and you have to let the phone fight you between 'no automatic date and time' and the network forcing the time.
Of course now i cant get the oem unlock trick working...
RE the dual sim issue... i think you would need the stock rom specific to your model try sammobile, see if there is a CRED release for your model. I cant guarantee it will work tho.

Thank you for your help, I am on the latest firmware now and into my Google and Samsung accounts. I am a little confused on the wording in the oem steps. I have tried it a bunch of times. Prenormal is still there, I already have the OEM unblocked, I can toggle OEM on and off but it doesn't change my rmm status. I am not sure what I am doing wrong.

Thats exactly what im now struggling with. It absolutely did work twice but i cant get it to go now.
Heres the thing - both times i did it before, i would turn off automatic time and date and set the date backwards, then reboot the phone, when it reboots, automatic time and date were rechecked, and the date reset to now (hence the 'fighting with the date' comments) ... i think thats important, because now when i try it, automatic time and date stay OFF, the date does not reset, and i cant get the trick to work anymore. No amount of wifi/airplane/mobile data on/off seems to change owt.
If anyone reading has any ideas it would help.

I see, so you suppose to set date back 8 days and turn off auto time and date and restart phone? When it comes back on to and set the date back to 8 days again? I thought you have to check the software? And then do those steps? So after I change the date back after that first restart, then what? Do I just turn OEM lock on and check download mode to see what the status is? I am not trying to be a pain o am just confused a little on the steps. Thank you for all your help

I think we might be looking at different issues.
This is to fix a semi bricked phone that has locked up its bootloader. In the past to resurrect a samsung all you had to do was flash twrp and your new rom but since Oreo some funkiness has been added to the system which only lets you flash a stock rom, (i.e. restoring a phone to factory settings and software) via ODIN/HEIMDALL then it locks up the bootloader for a week so you CANNOT flash anything into the phone that modifies the bootloader (i.e. TWRP OR *any* rom) until its timer runs out. This is most likely an anti theft feature esp with samsung and google pay use as it means there is no way to easily break into a stolen phone and use it as normal, and reflashing breaks all of the security features of the phone (e-fuse) - no knox no samsung or google pay no samsung pass as your device is insecure and could spoof false banking details etc.
The rom i linked to is important as it is a new AUSTRALIAN unbranded STOCK rom, that for some reason you can flash OVER a locked bootloader, meaning you can resurrect (australian at the very least) SN-G950F phones (exynos)
If you already have a working phone and can get to your developer settings then most of this thread is irrelevant to you.
Now - OEM unlock - You just bought a brand new galaxy from samsung (or youre me and you bought a MINT second hand one from cash converters for $700 less) - your phone is factory standard and schmicky. THE BOOTLOADER IS LOCKED. THE RMM STATE SHOULD NOT be triggered. If right now you went to flash something it would fail.
So you go to about phone - software information and you tap 'build number' seven times to unlock developer mode. Hit back twice and developer mode will be at the bottom of settings.
Click into this and you should see without swiping down 'OEM UNLOCK' - If you enable this, you can then reboot straight into download mode (power vol down and bixby) and flash twrp or whatever rom.
If you dont see this option, you either have a snapdragon model (youre **** outta luck permanently) or RMM is PRENORMAL and you either have to try the unlock trick(s) or leave your phone SWITCHED ON for 1 week and it will unlock itself.
The biggest issue at the moment is that i keep breaking something after i attempt to root so not sure whats happening there so use major caution.
Now as i said the trick posted above to unlock without having to wait a week (which i think youre asking about) im now not sure how it works because i cant get it to work any more.
Automatic time and date off, set date back 8 days, reset the phone. Do this a couple of times, then turn on automatic date and time again. HERE THERE BE ISSUES. When i first did it - i switch off time and date and change then reset, when the phone came on, auto date and time was on again. Turn off, change date, reset. Again, its back on. Turn off, change date, reset. Its back on. I give up and leave it, and notice later the option was available, so it worked. I broke the phone, reflashed again, did the trick in ONE reboot. Fcked something again, reflashed, now auto time and date stays off and the trick wont work so i cant help you with that until someone comes up with more info im sorry! Its a bit zarbis.
Im not going too nuts trying to fix it as i now have a fully working stock backup phone that sits on DeX plugged into my bedroom tv full time and im not into custom roms, root keeps breaking the phone, and ive sonce replaced it with a mint S8+ that im not even THINKING about considering rooting until its replaced maybe next year. Its not as easy to get around anymore and thankfully a) picasa and hangouts are no longer stock apps and can be banished and b) you can now disable all the other built in apps natively so its now a lot more bearable with a totally stock phone.

Hi guys,
So, a few days ago I decided to tryout One UI Beta 2.0. A few days it worked perfectly fine, but today, it said my pattern was wrong. So I read on the forums that more people had this issue, and that it was because of the beta. So I downloaded the original firmware for my device from SamFirm, and flashed it in Odin. Phone booted perfectly and I got through the setup progress. Then I wanted to set up a pattern but it wouldn't work. I need to register my pattern 2 times like always, but after that it ask me that I need to back up my pattern, so when I click continue, something comes up for a second that says please check your network connection. And then it just doesn't add it. I tried to install firmware 2 times now with Odin, but no luck, I keep getting the same message.
The first time when I installed the firmware when I got from the beta, I forgot to disable my google and Samsung account, IDK if that may caused it someway.
Edit: I updated apps in galaxy store, and now it doesn't say check your connection, it says backup completed. But it won't change to pattern for some reason. Stays on swipe to unlock.
I hope anyone can help me with this problem,
Kind regards,
Crewz
Flash your original firmware (not the One UI 2 beta) and after ODIN says done or successfully or whatever, unplug ya phone and boot into recovery and do a data factory reset. This should fix it.

A lot of people had this issue and it was fixed 3 days ago. After beta 2 I also faced the same issue. Dont do factory reset. Just install the third update which was emergency update to fix this specific issue. Download it from beta thread.

Okay, so with samfirm I downloaded my firmware and installed it with odin. So i tried the emergency update. I am trying to install beta 1 atm ( I read on the forums that you need to beta 1, 2 and the emergency ). but for some reason whenever I am trying to install it, I get the error "E3005 (LINK) has unexpected contents. Error in package.zip Status 7" I have no idea what to do anymore....
