please help me:crying:

I dont have IMEI! just a powerd off phone, red blinking led, it goes to flashmode and fastboot!

help me:crying: what should I do!!!

---------- Post added at 06:32 AM ---------- Previous post was at 05:33 AM ----------

uhoooo! I found the IMEI under the battery!

but a question! should I continue all the procedure recommended by sony unblock bootloader! and I wonder how I can put the code on flashtool!
[Sony Xperia L] LazyLucretia:
Have you solved the issue? In case you didn't, both flashtool and Sony's command line procedure works, so choice is yours. :)

I want to give some information to everyone reading this. After unlocking bootloader, my device got stuck on a bootloop. I tried the advice given here and flashed the latest stock firmware but it didn't help. Then I relocked bootloader but still no luck could not get out of the bootloop. Then I tried to give stock firmware another shot but this time I checked Wipe USERDATA and Disable Final Verification, and this time IT WORKED! My guess is that it's about wiping USERDATA so if anyone encounters an issue like this, give this a shot.

hello sir... me i ask something about my problem.... the flashtool can't detect my xperia L... i don't know but all needed files were already on my pc and i already installed the drivers for my model.. please help me... i need to do this because i forgot my pattern and the recovery email and hard reset through buttons didn't work...?
[Sony Xperia L] n78 shadow:
On which windows ??

---------- Post added at 06:46 AM ---------- Previous post was at 06:43 AM ----------

Yes you should wipe data (this why factory reset work instead of flashing the whole rom) cause the cache is set to null so you need to wipe it to rewrite the cache.
[Sony Xperia L] zlrhc:
i used windows 7 ultimate sir....and still tried to re do the process and still not solved...
[Sony Xperia L] n78 shadow:
Try this version of flashtool 9.11.0

It will probably work and don't forget to install the drivers in the driver folder of flashtool .

Good luck.
[Sony Xperia L] zlrhc:
ok sir.. thank you... i will feedback later...

With the new flashtool release update, I try bringing it back to stock ROM and I get an error ..

ERROR FLASHING - ABORTED.

Kindly help..:(

Don't use latest version, it doesn't work with xperia L! Use older versions like 0.9.18.4 , and it will do the job.

while I am flashing it sucks at this and won't be continuing

I tried updating the flash tool

I tried using the Sony companion but didn't work. it's getting an error

I tried relocking and unlocking the bootloader but it didn't work

sometimes it won't detect for unlocking and relocking

please help me
[Sony Xperia L] Chelsti:
After unlocking bootloader mine Xperia L is bootlooped. What can I do? Can you give me links for instructions and working links?

Thank you,

Merry Christmas!
[Sony Xperia L] Kungfu73:
Simply flash the stock rom again. As mentioned in Post 14, If it bootloops again, then ReLock your phone with flashtool. It should fix bootloop. then again unlock the phone, and this time it should successfully unlock the bootloader without bootlooping :)

Link for Latest Stock ROMs (Android 4.2.2 with firmware 15.3.A.1.17) :

C2105: ? Download page ?

[Sony Xperia L] signashoes007:
Hi! thank you for your reply.. But, after some trial and errors i made, i successfully unlocked my BL using flashtool last saturday! :victory:

I believed I already hitted thanks to those thread that helped me.. (even though there is no specific procedure, it is, just try to figure it out) ^_^

And, one thing, i don't think SDK Manager is needed.. I downloaded SDK,but I did not used it.. only Flashtool (Flashtool.exe, not FlashTool64.exe)

I use Windows 7 Pro Edition.. ^_^

Anyway, thanks!!

:highfive:
[Sony Xperia L] Navneet Suresh:
Android SDK was needed for official unlock method suggested by Sony and Flash tool 64 was for windows 64bit version only 32 bit one uses flash tool. :D

And you can use SDK to build your apps too... so its not useless to download it
[Sony Xperia L] signashoes007:
hmm..I don't considered it useless.. I said, I did not used it unlocking my bootloader.. it's two different things.. ;)

Anyway, I'm happy with my phone now.. thank you for your help! :highfive:

but still my phone doesn't boot up

what's the problem?

though the firmware was for C2104 but that can be used by C2105 as said in the thread. is it ok?
[Sony Xperia L] Navneet Suresh:
hmm

All the firmwares i.e. .17 of C2104 should work i flashed .31 FW of C2105 onto my C2104 it worked without any problem but i would suggest you choose correct FW i.e. FW for C2105 ..

Now your answer when you unlock your bootloader the Boot loader gets damaged thus you wont be able to boot up the flash a fresh FTF with Wipe Data & Cache then your problem will get solved happen to me when i unlocked too
[Sony Xperia L] Navneet Suresh:

Have you installed drivers ??
[Sony Xperia L] LcK:
Hi guys :)

Thanks for this guide, it was very helpful! I have a question about to flash the stock rom after unlocking the bootloader.

Originally, my device:

4.1.2 JB

C2105

15.0.A.2.17

NO BRAND

I have unlocked the bootloader and now i have to flash a stock rom but which one? In THIS THREAD there are many stock rom and i'm a little bit confused. Can I flash "1272-2166_R3A Central Europe UNBRANDED GENERIC FTF 2.17" rom?

Thanks in advance,

LcK.
[Sony Xperia L] Navneet Suresh:
:D ya

Ya i think so you wont face any problems mate it was uploaded by the user in the credits i have added it into my rom FTF collection should work if you face any problem kindly notify me :cowboy:
[Sony Xperia L] Taher.apk:
Yes i have installed drivers properly coz without that my fone wouldnt even go into fastboot my sdk works too i hav it plugged in in eclipse .....even though everything works i m not able to unlock command not succeded
[Sony Xperia L] Navneet Suresh:
hmm

Am :eek: :confused: :silly: i suggest you do a backup of your Original firmware via sony pc companion and then redo all the Unlockin procedures because once unlocked you will need stock FTF as unlocking resets phone memory and internal sd card acc to Sony. :good:
[Sony Xperia L] LcK:
Ok, thanks man :) now i have another problem: flashtool doesn't recognize my device because the driver is not installed but i'm really sure that i have installed the driver.

I hold down volume down and plug the usb cable, open flashtool and...

However if I try to reinstall the driver a error message shows to me that the driver can't be installed.

Now my device is stuck on the loading screen and i can't flash the stock rom because fastboot doesen't recognize the device

Thanks in advance,

LcK
[Sony Xperia L] Navneet Suresh:

[Sony Xperia L] LcK:
I'm on windows XP but today I'll try another pc with windows 7 and windows 8 by disabling the driver signature check. I'm really bored, my device is on stuck on the loading screen by two days :D

If everything goes fine I'll try to flash the 15.0.A.2.17 ROM (1272-2166_R3A Central Europe UNBRANDED GENERIC FTF 2.17) and the Vengeance kernel.

Can i flash the Vengeance kernel on my C2105? How i can flash it on my device? I need fastboot or flashtool?

I'm sorry but I'm a little bit confused...

Thanks in advance,

[Sony Xperia L] Navneet Suresh:
Dont install vengeance kernel it and the thunderzap one has the wifi problem. Stay in stock one for a while till the modified new sources for building kernel come out.. :D
[Sony Xperia L] LcK:

Does unlocking bootloader has disadvantages like in other xperias where it looses DRM and some content in the phone doesn't function anymore?
[Sony Xperia L] Marius Cristian:
I just unlocked bootloader this morning.I don't see any issues so far.

edit:i think the tutorial of unlocking bootloader isn't complete.after "You have successfully connected your phone via Flashmode" the program does it's "thing" and then tells you to remove the phone.but bootloader isn't unlocked yet.you have to connect your phone with volume up this time.the phone will entry in fastboot.here you'll enter the code & after this step tutorial is complete.correct me if i'm wrong...but this is how it worked for me.

I m currently on stock rom 4.2.2 but I want to install old rom 4.1.2 (15.0.A.2.17) on my phone so it is necessary to unlock boot loader or I just flash old firmware via flashtool? :confused:

Just flash the firmware and no need of unlock bootloader.

Try again flashing other ftf. and also check data and cache .

So no need to root or unlock bootloader to go back via flashtools.:victory:
