tmob software update

Anyone else received a software update this morning? I just did, it was like 41mb. Don't see any difference yet but I'm still looking.

It was a security update. Maybe to close possible holes that could have been used for rooting.

What is the date of your security patch level in about phone after updating?

Ss

I did get the update but was told if it was installed it may kill the chances of ever being able to root the device.. So even though it seems hopeless for root right now, i skipped this update.

LOL the bootloader is locked. So either an exploit is needed in the system ( not impossible one was found on the Verizon s6 and patched a week later) but samsung has gotten really good at not releasing with an exploit or they give us a way to unlock the bootloader

Chances of root are slim to none unless tmo provides a way to unlock the bootloader. Even if an exploit allowed root to be pushed into system the device would not boot due to kernel checks for system modifications.

i got "b6 " in the last 2 digits on build number

So should I update my S7 to the new security update. Does this new update improve performance battery life etc.? The security update is 41.27mb. That is the update that I am getting. So a Root for the T-Mobile S7 is probably never going to happen? If I update to new security update will it prevent bootloader to unlock even more?

We have seen leaked engineering bootloaders and kernels on other samsung locked bootloader devices recently which have allowed root (albeit not very practical root implementations). That is likely the best chance of getting root on this device, i.e. unlikely.
Hope I am wrong but I would take the security update without hesitation and settle in to the fact that root is probably not going to happen on this device.

OK I won't hesitate to take the new security update. But can you tell me if the new update 41.27mb improves performance and battery life? Can someone tell me their experience with this new update?

Yes it does improve the battery life. The initial update will some what drain the battery fast. Dont worry just allow it to completely dies then fully charge it. After 2 or 3 charge cycle you wont see a huge dip in battery drain like at the time of initial updates. I was furious at 1st as my phone dies in like an 3 to 4 hours usage as before i can be go a full day of 8-9 hours of heavy usage. Wity a full charge at 5am and dont have to fully charge it until 7pm is very impressive. Thats with web browsing, facebook, youtube and Pandora. fb Messaging

Huawei wants to stop users from rooting?

A tweet from John Wu a person who created Magisk:
"I am informed that a new Huawei OTA will make installing Magisk unable to boot at all. At this point I might just simply ignore this brand even exists."
First they stopped providing us codes for unlocking bootloader and now we won't be able to root our phones?
Is root necessary for flashing custom ROMs on our device? As I remember I only needed to unlock bootloader to do that on a Samsung phone.

Already in AL varient.Won't boot after magisk installation.As for now we can flash custom roms but I read that Honor is going to remove FRP lock switch,which will make you unable to flash at all.To be honest this brand is nothing but rubbish in terms of Android tweaking etc.

So what now? Even if we're going to get Android Pie update, we can't install it cause it would turn our phones into useless Chinese spying bricks?

We have already had a taste of Pie now,so for anyone who dont care EMUI 9 they can simply do with Treble Pie GSIs.Who cares about the ugly UI of Huawei?PE 9.0 and OpenKirin Pie AOSP are both doing quite great.

No, you don't need to have root to flash custom. But you have to have access to PC to flash it through fastboot
And i prommised to myself after that, that this was my lasy Huawei device. I paid for device that can be unlocked and rooted and now thay are taking this back from me. I wonder is it legal? Maybe we could give phones back now?

So can I update safely with OTA if somehow we get 9.0 update and then just flash recovery image through CMD and then flash custom ROM?
I kinda don't want to do it now cause it's a pretty new phone and still there's a chance that I'm gonna brick it but I really want that 9.0

IF huawei wouldn't lock anything else - yes. But on Huawei you flash ROM directly through fastboot (since all custom roms are treble ones), not in recovery.
However i wouldn't wait, because maybe next OTA will lock something else. and you will be forced to use EMUI.

Thanks for help.

For now, I'm up to B372, and still able to do whatever I want, fyi.

Keep on updating... and supporting the Apple wannabees of the Android world. They learned and stole the ideas they wanted from the community and now will completely lock out the devices, bootloaders, root methods, anti-rollback measures, etc.
Oh, and as for that "spying" part? Just search for "Huawei D.U.B.A.I.". Every single aspect, action, usage and telemetry of your device is logged and sent to Huawei's Big Data Analytics servers, and it's embedded on kernel and can't be disabled. Most i could do on my kernel was disabling it on GPU framework, but the rest remains. If i turn it off on kernel or eliminate it, the mobile comms framework is killed and sim card doesn't even get activated, turning your device into a small tablet at most... so you either accept it or get yourself another phone.
Since using Treble Roms gets rid of the "system" part of EMUI, like their store, services, etc, it's possible that the Analytics part is somewhat suppressed but i can't be sure of that.
My advice is, stop updating EMUI and go Treble. Or just sell your device and get another. Or just resign to the new Huawei's reality and forget this community.

SAMSUNG S8/S8+ SNAPDRAGON OREO ROOT discussion

I was curious about if there is ever going to be root for the s8 Snapdragon varient for Oreo.
I saw this thread
https://www.google.com/amp/s/forum....e-oreo-root-japanese-snapdragon-t3830039/amp/
If the Japanese Snapdragon bootloader can be exploited. Maybe in the future, the g950u/g955u can be rooted too?
If someone has information regarding this and knows developers who are working on this? I know that you can install safestrap on Oreo because of me1212(sorry if I spelled his name wrong) and partcyborg and other developers.
THIS THREAD IF FOR DISCUSSION AS IT SAYS IN THE TITLE. IT IS FOR DISCUSSING AND LETTING PEOPLE KNOW INFORMATION ABOUT THEIR SNAPDRAGON S8. Thanks for participating.

No. We use a exploitable nougat kernel. That samsung graciously left us open. The bootloader this day in age and is not exploitable to unlock. Specially on Oreo.
New exploits come along everyday so maybe one day. But not anytime soon. Me and several other look everyday for something possibly missed. But until some new major samsung bootloader exploit comes along which brings me to another point.
This day in age it's almost more worth it to only disclose any such exploits to samsung for nice payment.
The only known way as of now to unlock a U.S. bootloader in a engineering certificate which is branded by cpid to each device individually which means my cert will not work on your device. If not properly backed up mind you. Leaving you with a unusable device in several different ways. I know from first hand experience.

R.I.P My G950U oreo no root (T_T)

Does all this mean I can't root my G950U?

No just can't root Oreo or pie. There are methods on various revision bootloaders to flash a rooted nougat system

One last question.
I read that the Nougat firmware with Bootloader B1 can be rooted.
If I downgrade my G950u to Android 7, can I be able to root and flash Pie ROMs.?

You cant downgrade the bootloader. But there is this.
https://forum.xda-developers.com/galaxy-s8/development/root-t3904613
This allows safestrap on Oreo or pie. Which then you can flash the eng boot v5 which is a nougat bootloader but bit 5 then you can install su and a rev1 or 2 nougat system image. It sounds hard but really not bad. But the bootloader rev must remain that of 5

Thinking about rooting my Device before updating to Pie (should i?)

Hey guys,
after all these good messages (like DRM Backup/fix etc.) i consider to root my device finally, like i did with my old Z1. but im also interested in the new pie update to test it out. So im asking myself for some weeks now:
Should i finally root or wait till the update? i heard about the problem of downgrading that, once u get the update you couldn't downgrade to the exploitable fw. What's more, I want to keep my warranty (i know that drm backup is working but the message, that my device cannot be trusted is still there at every boot). i use several banking apps that checks for root and my experience with magisk and root hiding weren't so good at all.
Thats my current situation. Should i root or not?

Irrespective of the Android Version, Rooting on XZP requires you to UNLOCK the bootloader and loosing your DRM KEYS.
so the solution is either xperifix or posts in XDA offering kernels of specific builds for you to flash.
1. lets say you are on OREO and unlock your bootloader, if you wana root that oreo version, you must find the post on XDA offering modded kernels W.R.T that buildnumber for you to flash and flash drmfix.zip & finally flash Magisk.
2. let say you are on PIE, again you will do the same, but I am not sure they already have modded kernels available on xda or not. so make sure!!!
the third option is always (disputed tool on xda known as) xperifix.

Im aware that i have to unlock the BL and all that stuff that i have to flash, thats not the problem at all. im just not sure if i should wait for the update (since some people experience some problems and they said they couldn't downgrade) and root or not. im currently waiting for the OTA update since my provider is vodafone and they take their time before releasing the fw. the benefits of the new updates, that i heard, are just some fixes for Android, new design for the camera ui, full hd ultra slow mo and some ui changes on xperia home. or did i miss some new functions?

If you unlook the BL, OTA didn't work anymore : so you must upgrade the phone by yourself. Via newflasher or (if you've a ftf file flash tool) you can up and downgrade when ever you want. I didn't know exactly in this this moment, how to hold the user data.... you lost in this moment only the feature video enhanced (something with X-....) if you unlook the BL and upgrade to Pie

Help needed with S7 downgrading from 8.0 to 7.0

Hi all, I'm relatively new to the Android world and seeking help from experts here.
I recently bought a used S7 (SM-G930K), it came with Android 8.0 and I want to downgrade to 7.0.
I tried downgrading using its stock firmware with Odin. Attempted many times but only realized that it can only be downgraded as far as the bootloader version goes.
Think my S7 was on bootloader version 2. So as checked for the available stock firmwares, the "earliest" version 2 was still on Android 8.0 (PDA G930KKKU2ERJ1 and CSC G930KKTC2ERJ1).
Anyone can advise me how to go about downgrading to Android 7.0? Though this S7 may not be my primary phone and there's obviously no warranty, I won't want to brick anything.
Do I have to downgrade the bootloader version to 1.0 first? And how do I do that?
Apologies, do excuse these noob questions, I'm not familiar with many Android terms. Cheers!
Model: S7 SM-G930K (KT Telco)
Android version: 8.0
Baseband version: G930KKKU2ERJ1
Security patch: Oct 1, 2018

Basically, on Samsung phones, once you upgrade your bootloader, they put a lock on it, so you can never downgrade it, for security reasons, of course.
The only thing you can do is flashing custom rom, or stock rom with custom recovery & kernel.

I see, now i understand why..
"Custom roms" - does this mean it's made by users like us? And what does "stock rom with custom recovery & kernel" mean?
Can you point me where can i find these roms for my S7? Is it the same as flashing them on Odin?
Many thanks!

Yes custom ROM's are community made. The kernal is kind of like the foundation that sits beneath the ROM, so you can use the official ROM but run a custom kernal to tweak phone behaviour.
Flashing ROM's involves using TWRP instead of Odin. If you're going down that path I would recommend you read very carefully and educate yourself, instead of just gung ho'ing it. Wouldn't want to brick your device.
It's also worth mentioning while you can flash an older custom ROM via TWRP, that doesn't downgrade your bootloader with it. Having a newer bootloader on an older ROM can cause issues.
Most custom ROM's are also made for G930F, while some also support the G930K you may want to make sure before flashing anything.

Definitely will be more mindful as rooting does involve some kind of risk of bricking my phone.
Wow that's great info, really appreciate you explaining this to me.
Something new I've learnt! :good:
