I tell you I unlock it first, then I had problems with some widgets and I learned some new updates.
Then, I made a backup with Sony_Ericsson_Backup_and_restore.
After searching, I root my phone with "GINGERBREAK" downloaded from the internet (GingerBreak-v1.20) and finally settled "Titanium Backup" to remove some applications from my operator, then install the CLOCKWORDMOD (do not know what for) and and finally I started to flash ...
After root, flashing with FlashTool_0.2.9.1.
I suggested steps for flashing and inserted this update: "LT15i_4.0.A.2.368_Generic Global", with "wiped ...", which is to delete everything and set it to zero ..
Normal work for me ... I sent version 2.3.2 to 2.3.3 (thinking I would send to 2.3.4). It was great ... Then I appeared a notice of samsung (on phone), to install version 2.3.4 (4.0.1.A.0.283 I think it was that number) and when it started to install warned me he was going to shut down, spent 6 or 7 minutes and not lit. I tried to turn it on and vibrated, then vibrate him again and try to turn rang again, but soon ...
Then I could not turn ...
Once this happened I was like crazy trying to fix the COMPANIOM, but nothing ...
I flash again, this time with this "LT15i_4.0.2.A.0.42_ (1247-1041). Ftf" but did not recognize the flashtool as the first time coming out of the mobile code when you open the program loads and displays the model number of the phone, it did not appear.
Finally, press flash and began. (To this already, before, try reinstalling the Global LT15i_4.0.A.2.368_Generic where my computer does not recognize, nor giving flash, just not recognized out in red letters)
When flashing with the latest LT15i_4.0.2.A.0.42_ (1247-1041). Ftf, the normal flashing until the end. But my phone just did not work. The light that was on the side of my phone was green ...
I sent a technician and he said he could not ....=/
I hope you can help and serve as a case to be resolved.
Thank you very much, good luck!

Lenovo Yoga Tablet 2 830F - Android 5.0.1 - Lollipop ota update 2 from Lenovo (20/7/15)
Filename: YT2-830F_USR_S000195_1504220230_WW21_ROW_TO_YT2-830F_USR_S100067_1507101258_WW52_ROW.zip
Size: 1,15 GB
Link: https://drive.google.com/file/d/0B1j7Qr4n1Z15U3pXMTdNdHRfd1E
INFO !!!
My first update OverTheAir with this file was a fail. Only black screen after update and reboot.
(I think because i did not change the country code after flashing KitKat a few weeks ago)
(If the update stuck at 100% in recovery you also have to reflash KitKat ROM)
So i flashed original 830F KitKat ROM via "PhoneFlashTool" with this ROM / Tutorial:
https://cloud.mail.ru/public/Z2US9gd..._150422_ROW.7z
http://www.android-hilfe.de/thema/tutorial-wie-installiere-ich-das-kommende-update-wenn-es-nicht-funktioniert-fuer-alle-varianten.697884/
Changed the "Country Code Setting" via ContactApp ####6020# to "de" (select your language).
And do not update any app like Chrome etc. when it reboots again after.
Then download and start the Lollipop 5.0.1 Update.
Lollipop upgrade reboots into recovery and stays 5min. at 100%.
Then reboots into some intel-flash mode and stays for 4min.
After it reboots into Lollipop OS... :cyclops:
INFO 2 !!! (if you installed Lollipop update 1 first and now restoring/flashing of KitKat ROM fails)
matshias said:
I have the same problem, only that I had the first Lollipop version for 1050F with root and then got the new Lollipop update. The Kitkat version fails to flash. But here is what helped: Go to this post http://forum.xda-developers.com/thi...-8-10-13-3-t2930428/post60490907#post60490907
and download the LtoKKxml.7z and copy the files into the kitkat firmware folder and then flash using flash-LtoKK-PVT-810.xml
I had to remove the parts of the XML that erase and format data. Then it worked
After that I could flash KitKat!!

LOLLIPOP ROOT
So easy, follow steps 1-8: http://forum.xda-developers.com/android/development/intel-android-devices-root-temp-cwm-t2975096
I download "IntelAndroid-FBRL-05-16-2015-PTR.7z" and "UPDATE-SuperSU-v2.46.zip" and it worked with Lollipop 5.0.1.
Make sure you have all the Android, Intel, ADB driver stuff installed (for me win7 installed another one at rooting?)

Yup I got the notice a few mins ago. I also got it many weeks ago when it bricked my yoga 2 8.3
Advice, when it says Updating....100%. Leave it alone. Last time I thought it was done since it said 100% for many many minutes. So i thought it was stuck or bricked. Just let it sit. It will reboot by itself and restart to the next phase.
It will also sit on the Lenovo android screen for quite a while before it goes to Android is upgrading.
Yes, i got problems too!
- It stays for 8min. at 100%. I leave it alone...
- Then 4 chinese Buttons showed up.
- I pressed the first (reboot i think)
- it reboots, it shows the white lenovo text, then black screen with background light on.
- i waited 10min., no change or start into OS.
- then i pressed 15sek power off, light goes off.
- if i power on, again white lenovo text, then black screen with background light on. nothing... ???
i reboot into recovery and wiped cache, nothing.
i think i will make update from SD card again... see if something happend
Update again from SD dont work! it says:
"/system/app/Chrome.apk" has unexpected contents...
E: Error in /sideload/package.zip
SUCCESS, LOLLIPOP IS WORKING!!!
I Have restored original KitKat ROM via "PhoneFlashTool" with this ROMs / Tutorial:

http://www.android-hilfe.de/thema/t...icht-funktioniert-fuer-alle-varianten.697884/
This time i´ve made the "Country Setting" via ContactApp ####6020# to "DE" befor download and upgrade!
And i have aborted the automatic PlayStore updates for Chrome etc...
Lollipop upgrade reboots into recovery and stays 5min. at 100%.
Then reboots into some intel-flash mode and stays for 4min.
After it reboots into Lollipop OS...
So can you boot back into android? Even after you wiped it? If not and you can't do anything, call Lenovo. I think only they can fix it.
If you can get back into android, I would suggest waiting for the System update notice. That's what showed up this morning for me. I didn't have any chinese buttons. I didn't have to touch anything, just wait for a really long time which is unnerving because I don't know status.
I flashed the KitKat Version again, changed country code, and installed the new Lollipop 5.0.1 update again.
This time there are no chinese buttons to press. (i think because changing the country code befor update).
Lollipop is great, the display is much faster while scrolling in chrome etc.
Interesting. I wonder what the difference between the versions of the country codes are. Mine bricked last time it was updated to lollipop. When I got the repair back, it was back to kitkat and I couldn't update until this morning.
Glad to hear you got it fixed. A few of my apps also stopped working and I had to clear the cache to get it working again after the update.
There are some differences in pre-installed apps. I did not changed the country code few weeks ago because there are some apps in german setup i do not want...

You need to flash the stock kk firmware.

Yes, It looks like I cannot just upgrade from rooted KK. I had to go back to stock kk firmware provided in the OP's link and follow step by step instructions using google translate. thanks workdowg and 5m00v3.
anyone missing 5GHz band Wi-Fi support with country code DE? I cannot seem to change the country code once it has been upgraded to Lollipop.

Lollipop does not longer provide the option to manual change band... it will auto connect to 5ghz if possible.
It has nothing to do with country code DE. You can check your connection 2,4/5ghz with the app "wifi band".
My YT2 connects automatic to my 5ghz. And i have 2 networks (2,4 + 5ghz) with same networkname.

Okay, I found the solution ! Make the tablet totaly Off, press volume up and volume down, than press power bouton, you directly acces to fastboot mode, and here you can flash with Phone Flash Tool.
Hi,
thanks for the timming TIPs !!
I can't believe LENOVO dosen't take care of this basic things !!
Thanks to you Lollipop is running on my beloved Yoga.
A little tip while we are avaiting 5.1,
Go in Parameter
Activate DEV options : About this tablet, touch 7 times on "Build Version", it will activate the Developper Menu in parameters
Go to Developpers Option (in PArameter)
UNCheck NuPlayer in multimedia.
--> REBOOT your device
It will allow you to avoid Lagging into the UI and apps.
Note that in 5.1 NuPlayer has been replaced by a bugfree version.

Googling ”E: failed to verify whole-file signature" and each one talks about a corrupt download... They are old posts from 2013 or so but they could be right.
Try this version 2.40. You can update in the Play store once your rooted.

Thanks for your help.
I tried the 2.40 version triple check the zip file, aleas same error...
Also there are not only corruptions problems related... some are related to CMW version problem and lack of "unsign" option..
Again thanks for the 2.40 link. If you have any suggestion I'm all ears.
There is a new update, to yt2-830f_usr_s100191_1511230623_ww52_row
anyone tried it already?
Looks like it requires going back to stock KitKat again just to update it.
Can't really be bothered trying it.
Alright so im dead set on rooting my phone once i realised why the **** not. Im used to jailbreaking iphones and i used to do that alot. (man its so much more complicated on android).
and im god damn stuck on the first step already.
the freaking OEM unlock option is missing??? Im into the developer mode. its not there. Now i know you have to wait 7 Days, but ive had the phone for 2 months. Is it because Ive just updated it to oreo and it reset that timer so now i have to wait seven days... (im sadly a pretty impatient person, im trying to do this at 2am instead of sleeping)
I have an international version and i know its possible. Ive got the SM-G950F Model
Please help. theres so many different guides for so many separate things and old posts and different phones and models and situations.. :c
Same problem here. BUMP!!!
I have also the same problem. my model is G955f Exynos. after flashing official Oreo Rom, CRB7, then updating that to CRE3, I can flash nothing again, not TWRP, not Cf-root, not even nougat Rom. I have tried different versions of Odin, TWRP, and Cf-root but no result. And there is also no damn OEM unlock in Developers options. Does anyone have any solution?
someone has posted here a software named "Cygwin". Its Linux tool, so hard and complicated to use for me.
If anyone can find how to use "Cygwin" to erase Nand and flash again, please reply.

Go into the settings and turn off auto-detect time. And time to transfer a month ago. Next, the developer options disable auto-update. Then go into the firmware update to disable the automatic download and click on download updates. Reboot the device and it will appear. I always do that !!!

3. In developer options, I disabled auto system update.
4. In Software update menu, I disable auto download update.
5. Lastly, click the "manually download update" ,I received an error but that's okay.

I don't have Note 8 so I can't be sure but there's no harm with the steps I mentioned.
I actually tried to re flash it clean again(for the 2nd time) with Odin, and @altai1963's trick work again.
Why need 7 or more days when you can do this?
Just try it and let others know if it works for Note 8
Goodluck!

I don't own Note 8. I needed it for the article, it will be published on the XDA portal in a couple of minutes.
Does not work for me. Every time I reboot it shows todays date and no OEM unlock.
I go to "date and time" and set to 6 weeks ago, press done.
Disable auto update time.
Disable Auto update system
Disable download updates automatically
press download manually, get error "couldn`t download update"
reboot, and time goes back to today.
What am I doing wrong.

You just need to make sure your date doesnt revert to current date time after you reboot.
Can you try turning off the sim slot? or airplane mode(then turn wifi on)so that wifi is the only wireless connection u have.
I believe mobile data/sim network auto. adjusts ur time. Let me know if this works

Nope, same issue. Airplane mode, no sim,
could be that i have june update installed ???
I can set time forward and it stays set but going back always reverts to 26th june for some reason. not even todays date.
edit: ok, think i`ve solved it. I re-flashed stock firmware on Monday as I had "only official binaries" error, could that be why I cant go back further than a couple of days? It`s the only thing i can think of why I have this problem.

Sorry I cant help u with that where DATE & TIME is not sticking after reboot.
Im not sure whats the real cause but for me, the steps / bypass for OEM Unlock option is still working to me until now.
My device is SM-G950FD Dual XTC CRED build
sign into your google account (Must do)
and sign into your Samsung account
1)- change phone date manually back 10 days
2) go to settings - software update and check for update. You should receive errors messages sometime. Don't worry. Just ignore it.
3)- restart phone. After that go to settings -checking software update (when it says your phone is up to date) immediately go to Developer Options and you should see OEM Unlock appear back. You may need to try checking software update few times to get it work.
I tried that 2 days ago and it worked
So updated to latest CRG1 firmware hoping that would bring back OEM unlock function. Well it`s been over 3 weeks since update and still no OEM unlock option available.
Has this feature gone ???? It`s bootloader 3.
proven way 4 the oem unlock to reappear:
1. remove the sim card, factory reset
2. on setup screen, log in wifi, skip gmail, skip samsung account, skip the additional apps, set the time back 1 month (twice, because s8 will try to correct the time immediately)
3. untick automatically update, then check for update manually. then restart
4. sim card still out, phone self correct time, check for update manually again, then restart.
5. sim card still out, turn on developer mode, go on developer mode, wait 5 seconds n oem unlock is there.

Any luck?
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.

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.

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?

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.

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

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.
Hey all,
I am very much willing to wipe my phone to do a downgrade.
I have the OP8 Pro, unrooted (never rooted/never unlocked bootloader).
The scenario I see is - I downgrade my phone to 10.15.13 (I have the INAA modell). I'm sure at some point the phone will check for an OTA.
My question - Is it all possible for the phone to upgrade itself if it restarts?
Meaning, is there a time limit that the update is sitting in the queue waiting for the user to press reboot to install? Or can I just somehow figure out a way to silence the system notification of an update pending?
Not sure if that makes sense but my hope is to just go back to 10 and enjoy certain things that just worked out better for me unrooted vs 11 unrooted until some things are ironed out.
Thanks for your time.
No you would need to initialise the upgrade, unless you have automatic updates on.
You would have seen the initial installation begin.
Least that's my experience of it. The update is stored on the phone so you may also be able to delete it.
Turn off automatically download updates.
I downgraded using the special firmware I found (couldn't find official to do it ) and then installed the official EU/UK firmware straight after with no problem

Nice - noted. I think I can start my search as well. Looking to do this tonight.
