1050F: OTA Update #S100256_160119

Received this yesterday evening and am wondering if anyone has a good idea of what this update entails. It states is security patch and stability fix, if I'm not mistaken. Probably just a regular non-major update, then?

I am in the middle of returning my tab back to stock to then update to this update... Will report back in a while. @all
If you have unlocked your bootloader to use a custom recovery DO NOT UPDATE. It will soft brick!!! I tried in vain and am having to resort to 'back to stock' as, like a pleb, I don't backup before I tinkered

I happens to the best of us, man. Sorry to hear. I'm currently not rooted, but at some point will, so that possibility of messing up will ALWAYS be there.

i have just updated my yoga 830LC. But i forgot my bootloader is unlocked. It's soft brick. Can you help me how to back to stock Lollipop ROM. please help me! thanks

Do you have a backup? When I first tried to update I think it did update part of the rom. I reflashed the patched esp (which you should still have if you have unlocked you boot-loader)
It then let me in to recovery and to restore.
Try that and report back

Hi. I have this update from lenovo too, my 1050F is rooted, how I do a backup ? and you flash which stock rom, before upgrading ?
If possible, I want to keep my data.
Thank you.

I think the only way to keep you data is with something like Titanium backup saved to an external source and then whenever the update is finished re-root and restore selected backed up data

If you have unlocked you boot-loader you must have flashed a customers recovery. I did a twrp back up and selected what I want to restore.
Edit - get the files you need from this post

I have the 8 inch version of this tablet (830F) and received a similar update notification.
I just used the temp recovery trick to root and disable some bloat but left it otherwise stock. The tablet is currently in the process of backing up with temp TWRP and I was thinking of unrooting and giving this update a shot.
But it's not worth losing root over it...
Did anyone apply the patch in the meantime? Were you able to root again?
Thanks.

Yeah I have rooted, unlocked the boot-loader and flash twrp... All is good.
Have you flashed the patched boot-loader? If so you will need to flash the stock 830F ROM

Soft Brick
I'm just leaving my experience in case anyone does the same mistake as I.
I tried to use de "Hide root" option of SuperSu before upgrading, I have a locked bootloader, so I thought that it would be enough but I well... it didn't even boot after de lenovo screen
So I had to returno to stock, after reading what other peole did I manage to finally flash it back to stock lollipop.
I download this stock rom from lenovo-forums.ru

[As rookie, cannot post links :silly:]
Before flashing, the flash.xml has to be edited. Find
<string>fastboot flash system $system_file</string>
Click to expand...
Click to collapse
and add -s 1G to the command
<string>fastboot -S 1G flash system $system_file</string>

Then, enter on bootloader mode. I did it from de Recovery Mode (PWR on, and after de "lenovo" press both volume keys)
And just flash it with Phone Flash Tool
Everything it's probably pretty obvious for many of you but I leave this here for noobies like me! :victory:

Thank you 69PerTTu69.
Did you have keep your data partition?
I have understood you have only install system partition. Right ?
If so, I Will try to use your method.

Sounds good. No I only have the temp twrp bootloader pushed from the pc. Untethered it is stock but it's rooted. I'll revert that tomorrow and give this a shot. Cheers.

I have a new 1050F which has finished churning through all the updates to get it from KitKat.
It is now at the level of this update (..S100256_160119..)
I was about to root following the "[HOW TO] Root Yoga Tablet 2 [STEP-BY-STEP] [NOOB FRIENDLY]" 1st post instructions by AndroMAN (which uses a temporary pushed recovery) but I'm now a little concerned since that will put me in exactly the position of you -beluga-.
I'd be grateful if you could let me know how you get on (or if anyone else can comment on whether attempting to root this way is now a bad idea)

Ok, this was a success -
1. Unroot through the SU app (just to be safe)
2. Restart
3. Apply the update through the regular system/settings UI and wait for it to finish
4. Re-root as before (using IntelAndroid-FBRL-07-24-2015 and BETA-SuperSU-v2.67-20160121175247)
Keep in mind that I was on stock bootloader and didn't alter much besides disabling crapware. Deeper modifications may cramp your style.
Cheers

Has anyone successfully flashed SuperSU?

I see the *unofficial* TWRP is out, but a few people are having no luck flashing SuperSU.... Has anyone successfully flashed it? I'm going to hold off on flashing TWRP until this is resolved, in case there is another update between now and then.

You can root using this one UPDATE-SuperSU-v2.65-2015 , so far is the only one working unlike the most recent ones

Android Pay can't be used with an unlocked bootloader?

I just received the OP5 yesterday and unlocked the bootloader. I got the "Android Pay can't be used on this device" message when I try to add a credit card on android pay. Does anyone know if I need twrp and magisk installed in order for android pay to work?

Check by Playstore>settings... you're probably uncertified...
EDIT: You need magisk to pass the safetynet...

Correct. It says uncerified for me. The only thing i did was unlock bootloader. Sigh. I guess i have to twrp and magisk. Thanks.

Usually deleting Play Store data and cache fixes the "uncertified" issue. It did with my OnePlus 3/3T. It didn't work for me with the OnePlus 5 however.

It won't unless you either 1) Use magisk as mentioned or 2) use a custom kernel with SafeyNet patches.
When you unlock your bootloader, the prop (which you can read using a terminal emulator and typing getprop) has a flag called verifiedbootstate. If it returns anything but green SafeyNet will fail.

this is probably a stupid question but it's been a while since ive used android ... can you use android pay if you don't unlock the boot loader?

I've flashed v. 13 (https://forum.xda-developers.com/apps/magisk/beta-magisk-v13-0-0980cb6-t3618589) and worked as a charm!

I have both the newest version of Magisk and the manager, but I'm still failing safetynet, do I need to manually hide something else in magisk hide? Any help is greatly appreciated

Try the latest stable version of Magisk. It worked for me a few days ago while the beta wasn't (beta is working for me lately though).
You might want to reflash stock boot partition before flashing Magisk, I don't know if it will make a difference...

Thanks for the suggestions. I tried the stable version with no luck as well. I'll wait for the next beta version, and if that doesn't do the trick ill try reflashing the stock partition. If anyone finds a custom kernel that gets around safety net I'd really appreciate it.

I'm curious to know why one would unlock the bootloader if not at least to install custom recovery and root.

I don't know if this is OP'S reason, but you can boot TWRP without actually installing it... So you can take nandroid backups of an otherwise stock device.
Also, unlocking bootloader wipes your phone, so if you want it stock for now but think you might root in the future you won't have to deal with that...
TBH though, SafetyNet is working as advertised by failing an unlocked bootloader. We like to have our cake and eat it too.

Axon 7 Pre-Encrypted Data

Hey guys , Since I upgraded to Nougat, my phone is pre-encrypted and why can't I decrypt it? Why is it like this? I want to decrypt it so that my phone will be a little faster. So how can I decrypt it?

Unlock, install twrp and format data.

Zte stock rom comes pre-encrypted on every new install. The only way to bypass it is to edl flash a stock rom with twrp. Boot right into twrp after the flash. Find a modded stock boot.img that has a modded fstab, flash it, then boot and your phone will be unencrypted with the stock rom.

Thank you all. I'll do as you said and unencrypt it.

DEAR ZTE CUSTOMER,
Pls describe clearly about the situation of your encrypted phone, because our developer confused about such encrypted issues. BTW, please provide your phone'IMEI.
Thank you!

No issues. It is encrypted by default in stock ROM.

This guy seems to be spamming and looking for imei info.

Mine is encrypted. Brand new out of box, updated to B10 MM then to B04 Nougat 7.1.1
What are the implications of it being encrypted? Mine is remaining stock, not even TWRP recovery or root. I'm happy if it's secure as I have personal and work SIM in it and will be using a couple of apps that look for root. Kind of tired of modding phones, just want life to be simple and reliable, able to take updates when I like. The work Nexus 5X was a ****ty phone but I got used to it being updated. It's a rare one that doesn't bootloop and is on Oreo but I hate carrying two phones thus the reason for buying the Axon 7 for dual SIM.

I don't believe you'll get more performance out of an unencrypted phone, or not enough to justify it for that matter. also, on some phones you need it not to be encrypted if you want to see the internal storage in TWRP, but on this phone it doesn't happen.

You can fix it in your settings--hand design(sort of, I guess),or you can update the latest version from ZTE office website. Good luck!

Back to Stock with Oreo possible?

Hello my friends.
I bought my U Ultra in December 2017.
Now I decided to flash LeeDroid Oreo on my phone.
It works great.
I backed up in TWRP the parititions "System Image" and "System" in case for going back.
Now my question.
Is it possible to go for going to stock when I recover it all?
Can I lock the bootloader after that?
How to use the "System Image" partition? Can I fully flash my phone to stock with it? With Recovery and so on, because there is no RUU available for me?
My System Version was 2.21.401.1 and my region is Europe/Germany.
Regards

If you have TWRP backup you simply recover the backup, wipe data and you are back to stock-ish. Naturally due to lack of original recovery you won't be able to receive/flash OTA. For HTC you simply do not exist.

Kind of. You can make OEM lock but it won't be the factory lock. It will be relock. And if you have a custom ROM at that point the phone may not let you boot up.

If you restore whole system then you will get the OTAs. (This is how I upgraded to Oreo in the first place).
Problem is with TWRP/custom recovery not being capable of performing the factory update (people are soft-bricking their phones).

There is a topic explaining how to recover first to Nougat and then let you phone receive OTA for Oreo.
I don't know from where you can get RUU for your CID. Keep in mind it has to be the version you have or newer if you are not going to unlock the bootloader and use 3rd party tools to trick force update.

But I would know if it works without hard brick.
I am little bit afraid from it, because I tried this two years ago on my Motorola Moto G2. For one, two, times it worked, then came marshmallow with a new bootloader, so you bricked this phone like ****.

Yes, I did that. I went through the described procedure and restored the phone to pristine Nougat and then let it to update via OTA to Oreo.
If your phone is s-on then there hardly any chance you will hard brick it. Soft bricks can happen, naturally. But then, dependently on the case, you can recover from it by reflash, wipe or making the downgrade again via RUU.
One important key combination you have to keep in mind. By pressing (and holding) power with volume down you will see the buttons flashing. Keeping them pressed for ca. 15 sec (shorter, longer depends) forces the phone to reboot.
Good luck.

No Brick, but I had to erase the data and cache partition again after the first start, because it stucked at the HTC Logo after booting.

What software status? If you restore the original recovery there is no additional message during boot. If you lock the bootloader it will report as "relocked".

And to my knowledge it will be like that. You have flashed unlocked (from HTC but always) bootloader and this has to be noted. It is not that drastical as KNOX for Samsung, doesn't influence the phone functioning.
