Before a while a had tried to unlock the bootloader of c2104. After unlocking it went on into boot loops
In the same condition I rooted it and flashed Pactaoshan rom (cm11). In recovery it read package invalid or corrupted. However now it's fine with its stock rom.
Now I try to update it to Cm12. Do I need to unlock bootloader for it or would it work fine without it.
And if I need to unlock, can anyone explain it step by step from unlocking till flashing Cm12?
A video with step wise Guideline would work
Also I am keen to know why my c2104 didn't accept cm11 previously mentioned.
Waiting keenly for your reply.

Lol you're supposed to flash a stock FTF file once you've unlocked your bootloader. Then go through the steps of installing CM11/CM12. That is flashing boot.img from CM11, and then using the recovery menu.(Press and hold the volume up button when the led lights up during power on) Yes I know I said boot.img from CM11, that's because the recovery in CM12 cannot be used properly. In the recovery menu you can either flash the CM11 or CM12 zip file.
And what about unlocking bootloader?
Most of the thread says no need of unlocked bootloader
What is preferable?

Hello,
I'm trying to install TWRP on my wife's TFT300T. Its lagging and freezing bloat apps hasn't helped. It's rooted stock 4.2 with a locked boot.
I rooted it with motochopper, and tried installing the latest 4.2 (2.6) with the terminal method and it didn't seem to work. I get an error when trying to access the recovery menu. I tried using adb/sdk, but I don't see the usb option fro fastboot.
I have the latest unlock tool from asus, but I want to be sure I need to unlock the bootloader. I have everything backed up with titanium, but I'd like to get a recovery of the stock too if possible.
If someone could confirm I need to unlock the bootloader that'd be great. It hasn't specially said that I need to unlock the bootloader in any of the 5 or 6 topics I've read. Thanks!

To my knowledge and for a bit of backround the reason the tf300t needs to be unlocked to install twrp is any kernel package you flash needs to be cryptographically signed, the key for this has not and wont be released by Asus, meaning if you try flash twrp without being unlocked, the bootloader looks for a signature on said package but doesn't find one so its not accepted, unlocking the bootloader disables these checks so we can flash what we want.
Short answer
Yes you need to have an unlocked bootloader to flash unsigned kernels
Hi everyone!
I have a problem and I need your help. I'm using AVD Rom but I have locked bootloader ("Unlock bootloader allowed: no"). But I need help with flashing .zips. I was trying to do it via Flash Gordon but this application doesn't work properly for me and one time it caused bootloop in my phone. I wanted to flash Pure Performances™ but I don't know how. Does anyone know any program like Flash Gordon but more stable?
Thanks for help in advance

There are restrictions on CUSTOM ROMS which require UNLOCKED BOOTLOADER. However, some ROMS can even work on LOCKED BOOTLOADER. So every time you flash your ROM with locked bootloader, you will end up bootlooped. Sometimes, the ROM would work but some extra modifications wouldnot work (as they require further freedom which only unlocked bootloader can provide)/ Thus flashing Zips made for UNLOCKED BOOTLOADER will also result in bootloops.
The best way would be to check out which ROMS support locked bootloaders or if someone from your community comes out with a hack to UNLOCK your bootloader when you are not allowed.

I understand but most of zips caused bootloop if i flashed them via flash gordon. And I've read that Pure Performances modification doesn't need unlocked bootloader
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.
so, I've rooted with kingroot and installed dual recovery, then downloaded cm 12
on philz, I used that "prepare for new rom"
and went I went to flash the zip...... it was corrupted.
and so, I downloaded the zip on my pc and tried to flash it with sideload, it didn't work.
so I thought that philz sideload wasn't working and tried to boot on twrp
but, when I turned the phone on again, I couldn't get into recovery.
I can get into flash mode just fine.
pls help :^(
also, I can't get it to show on fastboot devices :^(
If u want to use Cyanogenmod, then u have to unlock the bootloader or else u will get a softbrick, anyway u can recover your phone with flashtool or with pc companion, after re-install firmware then unlock bootloader but as you know, u will loose drm keys (bionz etc), for working Cyanogenmod u need a custom kernel aswell so unlocked bootloader is indeed

I guess it must work, as long there is a patch for Z3 dual then it will work
you can use flashtool and a stock firmware to get your phone unbricked

I believe you need to downgrade to lp before you can unlock the bootloader and install twrp.

how to downgrade and what is the unlock boot loader ?
and when i bought phone what is the default ? that boot loader is locked ?
You may be able to use the Panasonic Eluga software to downgrade to lp.
You must unlock the bootloader to install twrp and cm.
Some info here: http://forum.xda-developers.com/idol-3/development/tool-tools-idol-3-5-5-4-7-t3441781
When flashing anything to any phone, things can go wrong; therefore, I suggest that you familiarize yourself with flashing and be ready in case of disaster.

You can't flash twrp unless the bootloader is unlocked. The bootloader cannot be unlocked on MM, only LP.
