[G928I]MM Bootloader from G928G

I tested it, G928G MM Bootloader works on G928I.
I tested it with this [ROM][SM-G928 F/I/C/L/K/S][6]Ditto S7 ROM [v6] from Electron Team[PC8] Thanks to GigilinE
Take a look at Attachment!
TAR File(sboot.bin, cm.bin) flash via Odin. (For install a ROM you need Recovery and Kernel for MM)

Hey mate,
Wanting to use AUDAX Rom using this... did you need to flash the 928G modem files as well or just the bootloader?
Thanks

Hey, i flashed the modem, hidden, bootloader and cm from this rom G928GUBU2BPD2_G928GUUB2BPD2_G928GUBU2BPD2.
It works great.

So have you uploaded just the bootloader here? Do you have the modem files?

Im in New Zealand with a G928I DVU2AOK2, Would this work?
If it would work how does one install it? ( I know how to use odin just need the ROM link and what to do with your bootloader files)
Thanks

I flashed mine to Marshmallow earlier today using Audax Rom,
This is the process I followed:
1- Put Rom in your device
2- Enable Developers options in your phone
Go to Settings / About Device / Software Info and tap on Build Number 10 times to enable Developers Options.
Then Go to Settings / Developers Options and Make enable "USB Debugging" and "OEM Unlock".
3- Make a backup of you internal SDcard and your data.
4- Power off your device
5- Reboot into Download Mode
(Press and Hold Volume Down + Home + Power button)
6- Open Odin 3.10.7
7- Put BOOTLOADER in BL
8- Put TWRP RECOVERY in AP (I had to specifically use this TWRP as the current one wasn't working for me https://www.androidfilehost.com/?w=files&flid=52574)
9- Connect device to PC and it added in Odin
10- Go in options tab and uncheck autoreboot (check only F. Reset Time).
11- Click on Start to Flash the files
12- Once it's completed and you see "PASS" in a green box, disconnect device and long press Volume Down + Power
13- Once screen turns off, immediately press Volume Up + Power + Home to reboot to recovery manually.
14- Once in Recovery, install Audax Rom and in Aroma installer select WIPE DATA.
15- When device reboot seems like a Bootloop but is normal. Than start Samsung bootanimation. Complete reboot ends after 7/8 minutes.

i´ve flashed this firmware complete G928GUBU2BPD2_G928GUUB2BPD2_G928GUBU2BPD2 and it works for me on my G928I! Only problem is LTE with O2 for me.
i think the best is install firmware. And then install recovery and kernel for other roms.

SM-T800 on Marshmallow 6.0.1 - How do you root or install TWRP on this?

I was previously on cm12.0 but wanted to get back to stock for 6.0.1. Got back to stock but now I can't stand the bloat. Has anyone rooted the stock 6.0.1 yet?

Just flash TWRP with Odin then flash the supersu zip through TWRP.

Thanks. I got through it all. It's been a while since I've rooted this tablet. My Linux laptop and Virtualbox eventually played nice. Also, apparently any old cord doesn't work. I had to use the original Samsung USB cable for Download Mode to work.

Thanks for the heads-up..
As I've never used TWRP before (always rooted with Chainefire''s CF-Auto-Root still not available for SM-T800 6.0.1), could you please post a quick step-by-step on how to root the new Marshmallow 6.0.1 on a SM-T800.
Much appreciated..

This link is not for our tablets but is the same process. Just make sure you find the correct TWRP version for the T800. Once you have TWRP installed find Supersu and copy it to your tablet's SD card. Use TWRP to install Supersu. http://www.cyanogenmods.org/forums/topic/install-twrp-recovery-samsung-android-using-odin/

I'm also on MM 6.0.1 having just bought this device. I'd like to install this rom:
https://forum.xda-developers.com/galaxy-tab-s/development/rom-android-6-marshmallow-tab-s-10-5-lte-t3219759
So how do I go about it please? Do I need to unlock the bootloader?
:edit: Followed the guide and got TWRP installed. Downloaded the Gapps (very slow download), SuperSu zip and Nougat rom from here. Did a wipe of dalvik, cache, data and system. Sorted. Only problem is I bought the tablet for reading comics and for some reason my comic reading apps can't "see" the cbr files on the micro SD.

So I have tried re downloading Odin and Twrp and flashing it. It passes Everytime. But when I boot to recovery with power home and vol up. It goes to Android recovery. Any tips solutions you could help me with? Thanks very much in advance

After flashing twrp in odin did you reboot to recovery ? Pretty sure u need to reboot to recovery to get it to "stick",
Otherwise I believe your tab will change it back to origanal recovery
DOWNLOAD:
1) Install the TWRP app from the Play Store or grab the apk from our website
2) Open the app, agree to the terms, and enable root access
3) Select TWRP Flash
4) Search for your device and select the version you wish to download
5) Once the download is complete, select the file (it's usually in your downloads folder) and then Flash Recovery
OR:
Most devices can be updated quickly and easily within TWRP if you already have version 2.8.4.0 or higher installed
1) Download the latest version from our website on your device
2) Reboot to TWRP
3) Hit Install and tap the "Images..." button in the lower right
4) Browse to the location of the TWRP image on your device and select it
5) Select recovery from the partition list and swipe to flash
OR:
You can find more information and download links on our website.

I had the same problem and I solved it by chance by finding a post online. It seems that after you flash TWRP with Odin it is indeed properly installed but you can't access it because when you boot into recovery it boots into Samsung's recovery. To get to TWRP you need to do the following:
1. Power off your Galaxy Tab S 10.5. Wait 6-7 seconds after screen goes off.
2. Press and hold the three buttons Power + Home + Volume down together until you see warning screen.
3. Press Volume Up to continue to download mode.
4. Reboot again pressing POWER + HOME +VOL DOWN but as soon as the screen goes blank immediately change to VOL UP whilst still holding the other buttons and wait.
5. Voila TWRP!
I hope it worked for you as it did for me.

Yes

It is not possible to install Magisk, because he is installing his own boot.img and i will be stuck at bootloop? Everything is working by the way, many thanks, but i flashed Viper4Android, it doesn't work, asks for drivers all the time.

Brilliant! Many thanks as I just got this device a few days ago so the timing on this guide is perfect! I had a little trouble after I flashed the BL_ENG_BOOTLOADERS where it constantly boot-looped but once I was able to get it back into download mode (holding volume down, home button, and power button) and start again from step 5 of the unrooting process everything worked according to plan then. I'm happy to announce I've rooted, customized, and unrooted thanks to the simple ease in which this method works so many thanks to jrkruse!

how compatible do you think this would be with the s7active (native to AT&T carrier) ?
especially now the S7active has recently been updated to Oreo, which also updated its bootloader to v4 ...
worth a go ?

[a520f] Bricked after flashing boot partition with heimdall no Downloadmode/Recovery

Hey guys,
i wanted to get lineage for my galaxy a5 and managed to install twrp and successfully and also flashed lineage 14.1 with for microg. It booted fine but no sim was detectet. On first boot wlan worked, when rebooted: no more wlan.... additionally it could not be turned off, because it automatically turned itself on again. Download mode and recovery worked fine. I read, that this problem occurs, when the phone ran with oreo before (what has been the case) and a possible solution would be to flash the nougat bootloader and modem. So i looked for mentioned files and found them in this forum (https://forum.xda-developers.com/sa...to/ref-modems-bootloaders-collection-t3799551). The instructions say one has to use odin to flash bootloader and modem, but i prefer linux so i use heimdall. But the files in the post above come in *.tar.md5 Format and heimdall did not want to accept that (at least the way i understood it). So i thought it would be intelligent to simply unpack the *.tar.md5 files. I received 3 files with *.bin ending, and i thought nice thats just what i need.
So next in Heimdall:
- i selected BOOT for partition name (instead of Bootloader)
- selected the first of the 3 files called sboot.bin
- no reboot
- put phone in Download mode
- connected phone
- click start in Heimdall
- flashing process
- wait a few moments
- disconnect phone
- restart phone manually
-> now when i try to power on or put phone into recovery mode/ download mode: all i get is black screen with red tiny writing in the top saying: "could not do normal boot. Invalid KERNEL LENGTH!"
i cannot acces Download mode or recovery or boot the phone
after many hours of research and no real progress i ask for your help.
is there still hope for my phone ? If Yes, what would be a possible solution?
grateful for your response

Your phone is probably screwed then. If you dualboot your PC and installed smart switch, you MIGHT be able to fix it.
But jtagging it is probably cheaper than buying Windows.

mh... i did make a little progress but i have no clue how it really happened... i ran windows on a VM installed Smart Switch connected the phone and somehow after a few trys it bootet into TWRP without button combination. So did format data, and wiped cache and System partition, reinstalled lineageos 14.1 (microg) + su addon and it booted. I then successfully started download mode to flash bootloader and modem as described above, this time with a windows pc (no VM) and odin. I did exactly as described in the post (https://forum.xda-developers.com/sa...to/ref-modems-bootloaders-collection-t3799551), but operation failed. Now i can still boot into the os but not into twrp or Download mode. USB debugging is turned
Here is how i tried to acces TWRP and Download mode:
Phone off: Button Combinations home+vol down+power -> boots into os
adb command: adb reboot-bootloader (device is recognized and authorized)
edit:
okay i did manage to enter download mode with the right timing of button combination.... (had to press them really hard...) still dont understand why adb wasnt able to boot into recovery...

Interesting, the error that you got means you were flashing too old of bootloader. Was it the newest version of oreo you could get?
Try flashing the whole tar.md5 firmware without extracting.

sorry for the late response. You were right, i accidentally downloaded an older oreo release and thats why i could not flash it. I now downloaded the newest stock rom from updato.com and it worked perfect.

Rooting with Android 10

My RN8P Currently has:
MIUI global 11.0.4 Stable QGGMIXM
Android 10 QP1A.190711.020
I only want to root so i can install 2-3 apps the need rooting.
I don't want to flash Roms or even have use for twrp.
Which root guide should i follow?
Do in need to Downgrade to Android pie?
will i be able to get OTA updates when rooted?

buddy the best bet for not hard/soft bricking is to downgrade to android 9 and install preloader and then root/install recovery.
if you want you can search "konah begonia guardian" on YouTube. he has quite nice guides.
regards

FYI this device is really easy to brick that one single misstep can brick your phone and mostly the only way to restore it is via service center. So you must really pay attention to each instruction on the guides. Most root guide need to flash custom recovery first so I guess its inevitable. In order to flash custom recovery, you need to downgrade to Android 9 or Pie, more higher version than that will brick your phone.
In order to root this phone, you first need to unlock the bootloader, refer to here for the guide. (Warning, just follow the unlock bootloader guide since the flashing twrp and rooting guide from there are kinda outdated and not recommended to follow)
Then you need to flash factory firmware (preloader and lk) so you can unbrick your phone in case you brick it, refer to Megathread for guide how to do it. After that you can flash custom recovery, then you can flash magisk via custom recovery to root your phone.

thanks :good:
one more thing , in all methods , after flashing twrp recovery and booting into it the guides say to delere a file called "recovery-from-boot.p".
i saw on telegram channel describing the same mathod but it also said that if i skip the deletion of that file the original recovery will remain , the phone will be rooted
and be able to OTA update.
does anyone know if its ok to do that?

I rooted from Android 10, and same with you, I only need to root to remove ads and install a few apps only.
I used this guide
https://forum.xda-developers.com/re...de-unlock-bootloader-flash-twrp-root-t3995919
Make sure that the twrp is the one that compatible with android 10, otherwise it won't boot to recovery.
Have mi flash app and android stock rom ready on your PC so that if you find problem you can always flash the stock ROM.

after reading a bit i think the right recovery version to root with android 10 is in the following thread:
https://forum.xda-developers.com/re...overy-twrp-recovery-redmi-note-8-pro-t4033695
and this is the procedure:
1. Download recovery file from this message
2. Open CMD from the dir where you store twrp.img (it's important because you don't need to type whole path of the twrp.img
3. Turn off the device, hold Power button & Vol- to enter fast boot and connect device to USB
4. In CMD type first fastboot devices to ensure that device is in fastboot, this is not important but recommended. Output should be something like this 4l6lsctgskpj4swc fastboot
5. Then it's time to flash recovery file. Type fastboot flash recovery twrp.img
6. This is the most important step now, on the device screen it should write USB Transmission ok if that is there you are ready to go. Remove device from the USB and hold Power button & Vol+, When the device turn off the screen keep holding Vol+ it'll keep screen off for about 5-10 seconds, then it'll show a recovery, still holding vol+ because it will get restarted again, and again still holding vol+ and recovery will show up. Simple words (Keep holding vol+ till recovery not appear for second time)
7. If it asks for a password, it's a password you use on the device it self(one for unlocking the screen or unlock the device after reboot), enter password and wait for Data decrypt.
At the moment there is no root and recovery will be replaced after you try to boot next time. To prevent it from replacing recovery do next (my opinion is skipping step 8. and 9. and having stock recovery because of MIUI updates):
8. Go to mount and tick the /system
9. Go back, tap on advanced, then to File Manager search for system_root dir open it, then find system and on the bottom is file called recovery-from-boot.p Remove that file and recovery wont be replaced
Now how we root it:
10. Go to advanced and tap on Close AVB2.0 and swipe to confirm
11. Go back and tap to Install ROOT, swipe to install and Reboot system
This will install Magisk v19.4, after boot you can update it from the Magisk Manager, my suggestion is to first update the manager then Magisk binary.
can anyone confirm that?

Yup, that worked for me on Android 10, global 11.0.5.0 QGGMIXM. The LR Team TWRP is the only one that worked for me, and I tried several.
Do make sure you download the v1210 for Android 10...
- in step 5, the 'twrp.img' you write in the command must match the actual filename you downloaded. Either change the name of the file, or enter the full filename in the command line.
- step 6 is kinda tricky. you might not get it right the first time. before installing twrp, i actually made sure i got the key combination right by going into stock recovery a few times.
When you do get TWRP up and running, the very first step is to set the language to English (unless you want Chinese). It will be the lower right buttton on the very first screen you are presented with (where you are asked for your password, if there is one).
I did not do steps 8 or 9, and TWRP has held. I did, however, reboot right back to recovery immediately after my first successful TWRP load-up. That may have stuck it.
The LR Team TWRP installed Magisk 20.3 for me. 20.4 is the latest, but I'm a little timid about letting it update. I had softbrick issues with trying to install Magisk manually thru this TWRP (instead of using the 'Install Root' button). Let me know if you update yours.

You can go follow guide from telegram group

i tried twrp avb2.0 but it gave me bootloop after power off and on again , it's better to get the avbmeta image file from fastboot rom(same miui rom you use) and disable it from fastboot mode.
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
