[Q] Unlocking my bootloader ? [Android 5.1.1/D2303]

Hello,
Excuse me for asking such question but I have never Boot Unlocked & Rooted any Sony smartphone so I'm confused here. I have only rooted LG and Samsung before without Unlocking the Boot as it was straight forward process. I have found this tutorial and everything is fine as I have got "Bootloader unlock allowed" in service information which confirms that I can root my Xperia. However when I visit the official website to get my unlock key it says that I need to be on software version 18.3.C.0.37 where my one is 18.6.A.0.175. Do I just use this official website to generate the unlock key and then use the flashtool to do it anyway ? I have use flashtool before but just for flashing the TFT file. Also after I unlock the bootloader how do I install custom recovery mode then install or back up the whole OS ?
If someone would help me I will appreciate your help. :good:
Thank You.

Ok, so right now you don't need to unlock bootloader to root M2 with 5.1.1. (At least not on 2306). Anyway, when you go to official website, they ask for your imei (after selecting your device). And then they give you the unlock code, they tell you how to unlock the BL with such code, with some SDK tools, but i prefer using flashtool since it does the job for me. So, after you open up flashtool, click on the icon that sais "BLU", it will ask you to select your device, you do so. After that it will ask for the unlock code, you put it in and click on unlock. After that it will do a procces, when finished, your BL will be unlocked.
I do gotta tell you, i've unlocked BL for 2 or 3 devices, all of the times everything goes right, exept once. After unlocking BL i ended with a bootloop. So for this case just turn off the phone, and flash any ftf. Bootloader will not re-lock after flashing.

Ok, thanks !
Also why do they say I need a software version 18.3.C.0.37 ? Could it be that their SDK tools require such version where Flashtool works on all of them ? Do you know how I can install custom recovery ? Do I still use CWM Recovery or something new and how can I flash new rom into it ? I have also heard something about emma when flashing rom ?
Thanks a lot for the help, I really appreciate it :good:

Sure no problem, about that i'm not sure, i've never had that android version issue before. For CWM you can get it here:
http://forum.xda-developers.com/xperia-m2/general/d2303-philz-touch-recovery-6-t3047492
Go to where it says "Download recovery" and download latest version (V0.7). Of course you have to be rooted in order to install. After you have root, enable usb debuging on your phone, and enable unkown sources just to be sure. Open the install.bat inside the file you just downloaded and follow the steps.
After you have CWM you can flash roms and other stuff.

[GUIDE] Downgrade to Marshmallow from Nougat Soak Test

Hey guys , many people were having problems downgrading their device so i thought i should make this thread.
I have downgraded my phone successfully and this should also work for other variants.
So let's Start
Prerequisites :
Phone with Unlocked bootloader
Drivers Installed
Phone Charged to 50%
Phone having Nougat Soak Test
mfastboot and adb
How To :
First Setup adb and Fastboot , by extracting the mfastboot-v2 file in the C:\ directory. So that the files are in a folder in the C directory. Ill name this folder as adb.
Download the correct firmware(Stock Marshmallow) for your device , I have links to all down below.
Extract the firmware files in the same adb folder.
Download the run.bat file . Link below
copy the run.bat file inside the adb folder
Open your phone in bootloader mode by first turning off your phone. Then pressing and holding power and volume down at the same time for around 3 seconds.
Connect your phone to your computer via a usb cable
Double click and run the run.bat file.
After the window closes. Start the phone by selecting the start option in the bootloader mode.
Tap the power button to start.
That's it Now you have successfully downgraded to Marshmallow.

Did you relock it ? I don't think it's possible if you are downgrdin from 7.0 as the booloader is upgraded

Yes this should work .

I have a locked bootloader and im on soak build NPJ25.75-2.
Do I need to unlock the bootloader to flash this new soak build. Or can I downgrade to MM without unlocking bootloader.
I dont understand that if I'm flashing official files then why do I need to unlock the bootloader.
What I want to do is to update to the lastest build of N from soak build without unlocking bootloader.

I think you'll have to flash Marshmallow as described in this thread. Then sideload the update OTA via recovery.
If anybody is unable to download from FileFactory (like me), and happen to be on the XT1643, download link for the stock ROM is available on this thread. Happy Nougat times!

it ll unlock the bootloader?

i tried to downgrade my XT-1643 from naught soak test but i ended in START UP FAILED. Yours device didn't start up successfully. Use the software repair assistance on a computer to repair your device. Connect your device to your computer to get the software repair assistant....Tried flashing stock mm rom but msg again and again appearing in bootloader

Back to Miui official ROM

Hi.
I'm right now on TS CM 13.1 and I want to try the RR. But I didn't unlock the bootloader officially, so I need to do it properly now so I won't end with an locked bootloader.
While I'm waiting for the approval... can I just flash the latest China dev ROM with my current recovery? Or should I flash it from fastboot?
Thank you.

Since you have a custom recovery, try Xiaomi.eu or miGlobe, though be careful as I think latest versions (Android 7) will lock the bootloader. To be safe, I'd flash an older version with Android 5.1 for now.

You can't try RR 5.8.1 based on Android 7.1 as it requires lollipop bootloader.
Or you can flash 6.12.22 and then update to any Nougat Miui Rom available on Xiaomi.eu. This is done via Updater app.
Sent from my Mi-4c using Tapatalk

I didn't realise there was a previous RR version with lollipop bootloader.
I already got the SMS with the approval from Xiaomi. I though it would take long. So, if get that right, I should first flash an older Android 5.1.1 Dev ROM and than update it with the Updater app to the latest version with 7.1 . This will lock the bootloader and than I can unlock it officially.
If I do it from from fastboot I can flash directly the latest 7.1 dev ROM, right?
Thank you guys. I always messed around with ROM's with my old GNex, but this Miui stuff confuses me a bit.

No need. Just go in TWRP and see the RR N thread there is a link to nougat blobs. Install that and then install newer TWRP that works with nougat (see android development). I think at this point you'd have to unlock bootloader. Then install room normally

But, as I read in the RR N thread, after I flash those blobs I'll end up with a locked bootloader if I previously unlocked it unofficially. As I did.
And, at least I think, I can only unlock it again from an official ROM. That's why I want to flash Miui.

Whether you have unlocked your device officially or not, it will still lock your bootloader. The key here is if you have the permission to unlock it. If not, then don't proceed. You can officially unlock your bootloader after 5 business days upon receiving the SMS.

Ok. I do have the permission. And can I unlock the bootloader right away with mi flash unlock on a custom ROM or do I need the official miui ROM?

Worked for me with no OS, so I assume you do not need miui.

After you flash the blobs, the bootloader will be locked. Unlock it via Mi Flash. Then flash a Nougat compatible TWRP and you're good to go in flashing Nougat RR.

Qualcomm EDL - Could this be the point of entry to Root and/or BL Unlock?

Found this series of blog posts that describe the Emergency Download Mode (EDL) on Qualcomm-based mobile devices.
This thread was made for us to discuss the possibilities around this mode and what benefits could we achieve for our phones.
I have not read them completely yet, but there is a mention of a Secure Boot bypass exploit against a Nokia 6.

xiomi EDL mode does allow to PUSH Twrp after altering the FASTBOOT ROM,
if Nokia is providing Fastboot roms then may be!
it doesn't unlock the bootloader! its just push Twrp so that you can flash modes to disable dm varity and magisk

Yes, it works but on Nokia5 and Nokia6 models only. Most of newer models does not switch to EDL mode. The question is still open: how to downgrade October SP to July to have ability of bootloader unlocking and rooting?

You have some choice to downgrade
Flash firmware via ost tool,ntool
Flash system via fastboot
If want root... Can use patch boot of trisi... Now nokia 8 more easier

I have no choice because I have updated to Oct. SP, my boot is locked and no possibility to roll back or atleast unlock bootloader. So EDL - is the only way to roll back to happy times with the root, freedom and customizing.

Before July update, YOU got unlock.key,
Then after septemer+ , before Pie-version, did you trie to get the second bootloader-unlock.key? because they changed bootloader? and also I am not sure if they givve away again from oreo and officail app a new unlock.key?
I don't dear to try out, fearing not getting anymore unlock-keys from hmd, need to secure more information.
I am trying to get a new key via official app but it is telling me that google play service isn't installed, although I downloaded open_gapps-arm64-8.0-pico-20190327 and was flashed via twrp and restored to original stock and still the official app is complaining about no play services when I am logged in to google-account inside the phone.
FYI: I donwngraded to oreo 8.0 and for experiment purpose I am trying to test if I will get a new key.

Thank you for replying. My problems are now gone, because I have recieved an official new bootloader unlock key. Now I have 2 keys for old and for new firmwares, so now I can flash anything I want with no fear . I downgraded to Android 7.1.1 and dont want to update any more. Now waiting for custom ROMs.

Question How to root pad pro 12? (TB-Q706F)

Is it possible? All i need is to make one file read only and the only way to do it is to root first i guess? I have unlocked bl already but couldn't find custom recovery.

android 12L. (https://dev.lenovo.com/ from link you can get boot.img... but you should wait for firmware for your device.
