Can you flash without rooting the milestone first? I'm planning to flash to a version that can be rooted and I keep reading that people have flashed using bootloader (power+vol up+camera buttons) mode but I can't find the instructions
Do want to flash a sbf file (firmware)? or a Modded Rom (like CM7/9, etc)?
if you want the first: you can flash without rooting the phone...
just download you sbf file from this thread http://forum.xda-developers.com/showthread.php?t=1465476
and use this tutorial BUT with YOUR sbf file http://forum.xda-developers.com/showthread.php?t=1032372
If you want the Second: you need root and others stuffs ..
sorry for my Argentinian-English !
I want to install a linux OS, however, I am getting errors concerning permissions and/or looped devices (I have removed Knox). I believe I need a different Kernel.
My device was rooted yesterday (Odin for PC), by a friend as I do not have access to a windows machine and couldn't get Odin working via a VM. I can confirm that I now have root access.
When I boot into download mode it says: qualcomm secureboot: enable (csb) - I assume this means my bootloader is locked?
Is it possible to unlock the bootloader, without using a windows PC, so that I can install a recovery and use Omega Files Pro (or similar) to flash an Omega rom? Is it even necessary to unlock my bootloader in order to flash a rom (my warranty is already void, but I do not want to brick/damage my phone)?
Thank you for your help.
Bootloader can not be unlocked at this time.
The locked BL makes it impossible to downgrade from KK to JB. But you can flash roms/recovery/kernel.
Read the guide that is linked in my sig to see how.

Just make sure if you're on KK then you flash a KK rom....
Hello Guys,
I was wondering if you can help me out clarifing a few things about flashing roms in .kdz format.
So i was on Cloudy 2.2 and had a lot of issues and then i decided to revert to stock. I followed the hyelton thread and did the TOT method. Now i have the phone on 4.2.2 working fine. At this moment i want to upgrade to 4.4.2 or 5.0 but when i check for updates i get the information that i'm on the latest SO. So my questions are:
1. How can i force update to 4.2.2 or even 5.0 without rooting? I tried to find the TOT file of a lolipop rom to flash via tool but can't find any.
2. I tryed to flash a .kdz lolipop rom via LG Tool (i extracted the dll and DZ) but i get an previousLoad error... so any suggestions?
3. The last case i could go back on rooting and put a custom recovery and then put the lolipop, but to achieve this, from 4.2.2 wich steps should i follow?
I'm asking this here because i saw multiple threads and discussions but can't get the right ways to do what i want.
Thank you very much.
Cheers
Note: The version is d802, portugal.
Well guys, after much nerves and errors.. here are my conclusions
1. If you want to use Lg Flash tool and flash a stock rom with .kdz extension, you need to put the rom file in the tool folder then run the tool with admin prev. Then select the file and press cse flash. You'll get an error on connecting to servers probably (i got one). Ignore it, but DON'T click on nothing.. the process is still runing, so even with error, just wait... you'll see your phone doing some progress. After a while it will reboot and VOILA
2. About TOT file, i just went with the kdz method.
3. To get the right KDZ file use thiss repo: http://devtester.ro/projects/lg-firmwares/
then you can put your imei and get the rom or just find a rom that fits you.
4. To get the lattest Lg Tool go here: http://lgflashtool.com/
Notes:
. Keep in mind that the .kdz files are big (>1,6gb) so make sure the download is not interupted, use a download manager or firefox. If its corrupted you'll have problems.
. All the files and sites are not mine, i'm just mentioning them.
Now running stock lolipop with no prob.
Cheers
HI all !
Today I was on reddit (https://www.reddit.com/r/Android/comments/4ek7ue/lg_v10_has_root_now/) , and I was asking myself if it was possible to repack .kdz / .tot file ? I know root method already exist for the G2 and every variants, but I think it's more easy for someone who wants to go back to stock to use a preroot stock file rather than re-root every time using actual method.
I already managed to decompress the .kdz file with this tool thanks to @bullghost . I download UpTestEX.exe , but now when I try to merge all files, I have thoses errors : http://imgur.com/a/LU7SH .
Thanks !
Hi,
I want to downgrade my SM-A310F to earlier Android versions, but Odin blocks this with the Error: "SW REV. CHECK FAIL. DEVICE: 3. BINARY: 2."
So apparently I can only install firmware files which come with the same Bootloader I'm currently on (so 3) and not earlier versions. For me it's Android 7 and the latest update of 6.0.1 which where made for this bootloader. But I want to downgrade to earlier versions of Android (please don't ask why, I know that these don't have the latest security patches etc. pp.).
So my first idea was I should downgrade the bootloader first so it matches the firmware I want to install. I extracted the recovery.img out of the firmware file, packed it in a .tar file and flashed it successfully through Odin. But unfortunately I get the same error in Odin like above when trying to flash the firmware again, so the bootloader maybe didn't downgrade?!
What can I do to downgrade my bootloader?
I want to install a stock Android ROM, so Custom ROMs are not an option. I heard I can install a Custom Bootloader, like TWRP, which allows installing every firmware?!
But does that trip my KNOX counter? My KNOX is still 0, so if there's an option to downgrade to earlier ROMs without tripping KNOX I'd be glad to hear it.
So I found the answer myself.
Apparently it is not possible to simply downgrade the Bootloader. I didn't fully dig into this, but to simply flash some image with Odin won't do the trick at least.
What works however is to downgrade to an older firmware with an older bootloader even if one keeps the newer bootloader on his device.
So what's the trick? One downloads the firmware file (.tar) which one wants to downgrade to and opens it with an archiver application (7zip). One extracts all the files to a folder and repacks them again in a .tar file but leaving every file out which ends on .bin (e.g. sboot.bin etc.). This .tar file can be flashed like any other firmware file via Odin and it should run through it without any problems.
I can not confirm that the downgrade works for every firmware version, but at least I could downgrade from Android 7 Nougat to 6.0.1 Marshmellow while the first one comes with the SW Rev 3 bootloader and the latter with SW Rev 2 bootloader. Again, I don't know how far into the past this works, e.g. if you can downgrade from 7 to 5.1.1 with this method.
Another option is always a Custom ROM (like this one for 5.1.1 for example) which doesn't check the Bootloader version.
I don't know if this method trips KNOX since I had tripped it already before figuring this out (very well could be, since you're not flashing a signed firmware file anymore...).

Hello,
My phone has updated on the last version of Android 8.0.0 Oreo (01.12.2020), with the last version of Bootloader (7th). I want to downgrade my device to Android 6.0.1, but all version for this OS have BLv1, so I am in the same situation than you (but one gen. later). Can I downgrade my phone, with the same methode ? If so, can you explain this in detail or give me a custom OS ? Thanks in advance.
I tried with this methode and this doesn't work : Odin has shut down when I have started the process. What was wrong ?
Downgrade using old versions of LineageOS?
Hi, I've got the same problem: I installed LineageOS 17.1 (Andoroid 10) which upgraded my Bootloader to 5. Now I need to go back to stock ROM but cannot do so because the error says: "SW REV. CHECK FAIL (BOOTLOADER) DEVICE: 5, BINARY 1.
Is it possible to install an early Lineage OS that downgrades the Bootloader and then install stock ROM? Where would I find the BL version of LineageOS?
Thanks
PS: In my case Galaxy S8

How on earth did you do that??
Which archive are you talking about when you say you unpack all the files and repack them without every .bin file?
I'm guessing the BL archive because that's the only one with a lot .bin files in it.
So I tried the BL_xxxx.tar.md archive and repacked it. But Odin would always get stuck at "file analysis..."
Also did you flash the modified BL first and then the AP, CP and CSC or did you flash it all at once?
I've got the same problem here. I want to downgrade my Galaxy S7 from Android 8.0 to Androud 7.0 but am unable to do so, to the point where I'm considering buying a completely new device just to have Android 7.0 again.
There is a way but...only Samsung's engineer are able to hack / trick this.
It is require special file to flashing in device then Sofware protection will be removed
Ask an Samsung Mobile Engineer if you have relatives.
