How do I unlock bootloader? ( rooted sm-217s) - Galaxy Tab 3 Q&A, Help & Troubleshooting

Ive Googled, Ive Binged, I have searched here until there is a sea of followed links and still am clearly missing something that must be right in front of my face.
I would like to put a custom rom on my tablet. A custom recovery is a necessary step from what I understand. So many tutorials including the one at TWRP's website themselves don't mention that you need to have an unlocked bootloader first. I have tried the TWRP Manager app and it says that I need an unlocked bootloader before I can flash a recovery.
How do I unlock the bootloader? I can not seem to find a tutorial or even any discussion of it in the Galaxy Tab 3 section here and I have spent many hours today trying to figure it out.
I stumbled upon the app Flashfire. It seems promising. It it what I need?

[Q] Rooting 4.0.2.A.0.62, already have an unlocked bootloader. Help?

So folks.
Just reached home with my new phone, an Xperia Arc S LT18a, I believe.
I'm stuck with this firmware 4.0.2.A.0.62 which doesn't seem to have an easy way to get a custom ROM on it yet. Sucks that I didn't read about this before heading out to buy a phone.
I went through one of the guides here and had the bootloader unlocked via Sony's website. However, the rooting instructions didn't work. So searched further and realised the issue.
I've seen people say that they've done it by downgrading to a lower firmware, rooting it and then upgrading the firmware OTA again. Then I read that upgrading firmware OTA with an unlocked bootloader will brick my phone. So I'm not trying that.
Any help on how I could go about this? Simple step by step instructions would be very welcomed, since I don't really know much about flashing various bootloaders and ROMs considering I just bought the phone.
Thanks for reading!
there are many threads relating to this problem....plz read & search before posting....
Well i believe the answer to your questions lie in this Thread ...

How can I have CWM on my phone? If I will flash phone I will do it with rooted ROM not stock. For me it's closed circle because I need root'ed device to load CWM on it, and I need CWM to make root.
Can someone explain me it?

With unlocked bootloader, one can easily flash a custom kernel with CWM, then flash the zip file.

What can I do ?

Hi all
Ok it's a long story but I think you guys need to know.
Ok I've got a arc s which isn't rooted and bootloader is locked (i think), running the latest stock rom.
I want to get a different rom like CM9 or CM10 because stock rom is almost unusable but I need to unlock my bootloader and root my phone, but everything I try to do those 2 things just fail for some unknown reason.
I have no idea if the latest stock rom is rootable yet, but I've red up that you don't need to be rooted to unlock the bootloader
( I'm not 100% sure on that).
But when I try to unlock my bootloader my phone won't boot into fastboot mode, (I know how to do it but it just goes into the charging screen).
and when I try to root my phone the program i used just gives me a ton of errors and phone isn't rooted when it's finished.
( I used doomloards ICS rooting method )
So I question is
Is there any rom I could flash in my phones current state because I HATE stock rom, I just can't use it without it rebooting all the time.
If so please post a like to the rom
Any help will be appreciated.
Read the stickies, look in the development section.

Install CWM and flash a Rom for locked bootloaders (eg. JJ`s Hybrid Rom )
P.s. : Have you checked if your botloader is unlockable ? Have you tried to unlock it at sony website ?
And if you realy want to unlock BL and root your phone... do some more reading. You will find at sony website all the info you need to know about how to unlock your bootloader. From there it should be very easy to flash custom kernel and Rom (custom kernel comes with CWM integrated).
Ok well I've looked a bit more at sony's website and found the unlocking bootloader page http://unlockbootloader.sonymobile.com/instructions
But when I entered the code in the dialler, nothing happened...
Also I've found this thread http://forum.xda-developers.com/showthread.php?t=1642480 which looks useful enough but I follows the thread to the rooting pages

I've had this problem before, when I was trying to root my phone, It just kept failing.
I saw some threads on installing CWM but they all seemed to require root access. so at the moment I'm ******.....

OTA's DO NOT RE-LOCK BOOTLOADERS.
Use the FXZ in the development section to update to 4.4.2.

Thank you! The instructions for this process are a little tough for me to understand. Is there just one XML that needs to be flashed using RSD Lite? I was reading on some of the posts that the XML needed to be modified before I flashed.
Do I need to be on stock recovery or flash to stock JB before I do this?
Also, I've never used RSD Lite. Is it a pretty striaghforward program? I cant seem to find which version is the most recent one and where I can download it.

RSD Lite is really easy to use, It's literally 2 buttons. 1 to locate the FXZ and 1 to start the process. You dont need to be stock or anything to flash a FXZ and FXZ's are more then a xml file, It's the complete system. As far as editing the .xml... I dont see a need to do that. I never do it.

ZE500CL Rooting and other related stuff

It seems that few ever talk about the ZE500CL variant of the zenfone 2. I've read a whole lot of posts on rooting, unlocking the bootloader, and installing TWRP, but most do not even mention this variant.
I started this thread to collect some information about this device. I would like to know from those who have this device, what has worked for you so far, and what hasn't? I'm especially interested in finding out the 3 things mentioned above.
I've only recently bought the device, and I only rooted it (though I did first get one bootloop already). The method that worked for me is described in this thread: http://forum.xda-developers.com/zenfone2/general/root-ze500cl-z00d-t3116531
The OP of the thread linked above also said that the second method on this thread: http://forum.xda-developers.com/zenfone2/general/root-newbie-root-instructions-zenfone-2-t3114063 works as well.
Btw, make sure the drivers are installed, else the computer won't be able to recognize the device when it is in bootloader mode.
Installing Xposed works as well using the ADB method mentioned in the thread linked below:
http://forum.xda-developers.com/zenfone2/general/guide-to-install-xposed-installer-t3116476
I can add any info you find to the device index in the general section for the 500CL.

How did you fix/handle the bootloop?
Do you know if it is possible to update the phone after rooting it?

Sure, that post is much more likely to be noticed than this one. Although I might not find out much. I'm a lot less daring without custom recovery. Hence this thread.

Well, seeing that I do not have a custom recovery (bootloader is still locked), I had to do it the hard way, reflash stock rom. Good news is, apparently your userdata (installed apps+settings and internal memory) is not wiped in the process.
First, you gotta download the rom. Get it from http://forum.xda-developers.com/zenfone2/general/index-asus-zenfone-2-wip-t3149748. Although I got mine here: http://www.asus-zenfone.com/2015/03/asus-zenfone-2-stock-rom-ze500cl-ze550ml-ze551ml.html, which is the old version.
Second, go into recovery mode (from bootloader mode), and use adb sideload ("apply update from ADB") to flash the .zip downloaded before. This is described under "Flashing Zenfone 2 via ADB" on this thread: http://forum.xda-developers.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596
Btw, the bootloop was caused by a mistake I made, not the rooting process.
any news update in our bootloader? hope someone could work for that..

After more than a week of feeling unsure to update mine to WW_12.16.5.118, updating it today after finish uninstalling SuperSU. This is what I have done.
1 - uninstall SuperSU from SuperSU setting - reboot.
2 - update firmware.
3 - re-root using Temporary_CWM method as describe here
Chinaphonearena said:
Method 2: Root through temporary CWM
This is a temporary CWM with the primary purpose of injecting SuperSU onto your Asus Zenfone 2. It doesn't permanently replace recovery. This process looks long, but really is bam 1,2,3 done. Just laid out step by step for the newbie.
link removed due to post count limitation
Unzip the package
Copy SuperSU.zip to the base of your SD card
Enable USB debugging (Settings > Phone info > Tap build 7x > Back button > Developer options > USB debugging)
If you don't already have ADB drivers installed, you may need to [post count restriction] and install them (most PCs have them already, but trying installing these if you're having trouble getting your PC to issue commands to the phone via USB)
With your phone on, attach it to PC via USB
Run 'cai_dat_CWM.bat' from the CWM package
In the black command window that opens, type ACCEPT
Type T4
Phone will reboot into fastboot and you'll see commands being issued from the PC cmd window copying the temporary recovery
You may see some funked up images on your display for a bit. Remove the USB cable and within 30 seconds should then see it booted into CWM
Select install update
Navigate to SuperSU.zip and install
Bam, done.

4 - Success!!! now my phone are rooted and all rooted apps installed previously are working.
Note: Previously (before updating FOTA) I also root my ZE500CL using Temporary_CWM since One Click root method aren't working for me.
Recover from bootfreeze while fully stock
Well, after getting a bootfreeze being on a fully (old version) stock ze500cl (Z00D), I figured out something useful. How to recover from a bootfreeze with locked bootloader, non rooted stock rom, without loosing what was saved on your internal storage.
Given that you have not messed with system files (since you aren't rooted), I'm assuming you got either corrupted userdata files or your internal storage is so full, the phone fails to even boot. I had the latter. If system files are the problem, this method might (or probably?) not work. The trick is to use tethered TWRP for backing up your internal storage.
1: Download CWM_Zenfone_2_Intel.zip here: https://www.mediafire.com/folder/w70w7r1a65840/Zenfone_2 (gotten from source 1)
2: Download Recovery.zip here: https://drive.google.com/folderview...T0xRMVRkcTg3MHdlc1o0cVFBc3RPeTQ&usp=drive_web (gotten from source 2)
3: Extract the zip from Step 1.
4: Go to the FB_RecoveryLauncher folder you have extracted, and replace the recovery.zip there with the one downloaded in Step 2.
5: Boot into your stock recovery and connect your phone to the computer. Make sure you have adb and the phone's drivers installed (gotten from source 3).
6. Run the cai_dat_CWM.bat script and you should boot into temporary TWRP recovery after a minute or so.
7. Use TWRP to copy your sdcard folder (internal storage) into your ext_sdcard folder (external storage/microsd) for the sake of backing it up.
8a. In the case of having too full internal storage, simply delete some things in there, and you should be able to boot it again.
8b. Not tested, but in case of corrupted userdata, a factory reset is probably necessary, and will solve the bootfreeze issue.

Thank you so much for providing this thread. Found it after hours of scouring the internet in search of help after somehow getting my phone locked in boot-loop. There isn't much support for the ZE500CL, but I will be posting on some blogs while I begin work on mine, and I will reference others to this thread and the few others I've found. Thanks again! :good:

Sorry, was out of town for 3 months. Glad to be of help. You know where the thanks button is .
I should note that the this phone is now the daily driver of both my parents so I stopped tinkering with it, although I left one of them rooted (and the other not lol). So don't expect more updates from me sadly.

This is my first time asking questions as I have always been able to reverse-engineer (R-E) or as the hacker in swordfish would say "the code just comes to me". Ive been around computers since my dad took me to work at UT and commands were issued with punch out cards....I've been a long time android self taught enthusiast turned professional. ITT Alum etc. I research, I surf, I R-E, and I try every possible option etc...only this has me stumped. And this is the first android that has stumped me. I double checked everything but I keep getting this error in BBQLinux: I followed all pre-update instructions to the T.
fw: ATT_12.16.10.92

This package is not for ATT (WW)
E: Error in /sideload/package.zip
(Status 7)
yes I did with root cmd line, yes cd to zip file location, yes I verified correct fw, even tried different fw zips ZE500CL downloaded officially and from here.
I greatly appreciate any help and I do apologize for "asking for directions"

Cool, I didn't read anywhere about unlocking BL first otherwise Ida made that "turn at the first light". We will ULO thru Asus and continue on our journey. These little Asus trinkets are little buggers being Intel based. Only line of Android devices that have ever stumped me. I am much obliged, fellow XDA brethren. Much obliged.
After pondering a little I came to this conclusion:
UL BL is basically the first step one should take when doing any kind of flashing of internal partitions be it a boot.img, recovery.img, FW etc... at least for the higher end devices. I don't recall having to do that for my sm-n900t recently. Does it only apply for flashing back to stock and not custom roms? Although I didn't have to UL BL first when I heim-dall/Odin flashed my note3 back to stock rom after being boot-looped. Cause once I did that I was able to try out a majority of custom roms available for it whether flashed thru HD/fastboot, Odin, via twrp update zip, or adb sideload. Hmmm, I might understand once I think it thru and look at all the different variables.
Good day gentlemen.
Be vewy vewy quiet, I'm hunting androids...
:good:
@cuervo233 Yes most devices you have to unlock the bootloader first. But there are some devices that already come unlocked. And then there are even some that have bootloaders that cannot be unlocked due to carrier restrictions. In order to get custom recovery to boot you must unlock the bootloader or it must come unlocked. With a custom recovery you can Flash the stock zip file from the Asus website or a custom ROM have fun

Thank you. I was able to ULBL, flash TWRP, flash to ww 118, root, and now its time to explore the neat wonderful world of custom ROMs. This was by far the hardest yet. Next in line is the cricket Stylo which was also giving me hell, but now I dont think I should have any problem getting it done. I'll keep ya'll posted.:good:
Lg stylo should have way more development, have fun brother. Remember tmobile phones( cricket, walmart family mobile, and metro pcs) you can easily unlock the bootloader . att on the other hand usually has locked down bl.

Recovery mode install

Hi
As a complete novice can someone please point me to an idiot proof guide of either installing or getting to recovery mode on this device ? I have searched the forum for days and all I get is unintelligible jargon and dead download links.
So far I have downgraded from lollipop to kit kat unlocked the bootloader rooted and flashed numerous random Romsey to no avail. All recovery options either aren't compatible incomplete don't exist or are so convoluted I don't know where to begin. I have xzdualrecovery but it is a zip file and what am I supposed to do with that if a can't figure how to install it? My old Samsung smartphoneso are so much simpler.
I have been using flashtool king root as these are the only pieces of software which make any sense to me.
Ultimately all I want to do is install 4k and timeshift but this is like pulling teeth.
Many thanks
From the first page in the general section, if you've unlocked your bootloader simply flash this. http://forum.xda-developers.com/sony-xperia-z1-compact/general/twrp-3-0-1-amami-t3350827 or one of the kernels that contain it in the dev section.
