i have follow your step, n now i have great lolipop for my xperia s. but it become unrooted device, n i can’t boot in recovery mode. what i do to solve this ? “sorry 4 my bad english”
Well i installed pure aosp lollipop on my xperia s and its unrooted too like u said… Any solution how can i root it again? :/
@telendar:disqus that is not a stock ROM. You have installed a custom ROM, that is probably pre-rooted. You need to install a stock ROM and only then you can root your device according to your liking.
But how can i install stock ROM? And can i install cyanogenmod 12 then? Ty 🙂
@telendar:disqus these guides will help you.

Oh 1 more thing 😀 is it possible to give me link for that FTF file for my xperia s? 🙂 it would help me a lot ^^
Wipe userdata, systemdata and cache before flashing the ROM and it should work fine then.
Type fastboot devices and press Enter.
—– After this step My device has gone in continuous reboot loop. SONY logo appears & reboots again with PINK LED on. I tried 2 times . Please help
@shahajipatil:disqus you haven’t even flashed any file yet, the phone shouldn’t go into bootloop. Can you provide a little more details of what you’ve done ?
its after flashing TWRP custom recovery
wow… im going to installed this on my xpedia lt26i …i will review the result later
DONE. It works well. Thanks the guide.
One more question: I cant find walkman in this. Are there anyway to take it to lollipop?
i believe you got your problem when you had done at step 17 (flash boot.img). Custom recovery is not causing this issue. You can try to flash “step 17 fisrt”, then do “step 10”. After fastboot reboot, press volumn up down for sometimes to go to recovery. Flash rom.zip then let’s enjoy yourself with lollipop…
Cheer …
p/s: you have to wait more than 5 mins at the CM logo before go to the android installation.. Lets take the coffee and let your fone do it 🙂
wow..DONE
I got the problem with google services has been stopped…I only wipe the cache and david cache..
Maybe this processing the full wipe to work…let’s try
My bad..i forgot wipe all before flash rom..that’s why …gapps JB cant run on lollipop .. lol…so google service fail for all for sure kakka…
It works well for now. I don’t see any error…Maybe it will appeara in some next days hahah…thanks the guide
DONE… I dont see any bug for now. Maybe it will be appeare in some next days. Let’s see 🙂
This is awesome…my xpedia is running lollipop now…

I used “adb push file.zip /sdcard/” I know It’s an year since you asked but It could be userful to someone else

@disqus_jbV8QroH3Z:disqus Try again. Could be an issue with your internet. The link is working fine.
Hello. I updated my Xperia S LT26i for this version but i’m having problems. My device has internal storage of 32 GB but the system does not recognize. Any solution?
Help me please! After flashing recovery using the given method (step 10), I can not boot in to system. I can’t access the phone’s internal storage (step 15). Whenever I select the option ‘reboot to system’ it takes me back to the TWRP custom recovery. Please help me.
You have not flashed rom in the tarp mode?
You might have to wipe caches of device to resolve this issue.
The gapps is not downloading for me
pls help i have the same problem after flashing the boot.img i cant reboot system dont know whats happening i followed all the steps from the beginning and i got stuck here how can i do it all from the start ?

@disqus_fOv4JbrnJT:disqus Try wiping cache/dalvik cache from recovery. If It still doesn’t boot up, flash stock firmware to recover your device.

My Phone is not entering into recovery mode after step 19
@dhaval connect your phone to your PC and in ADB command window run this command: adb reboot recovery
see if it boots into recovery mode or not.
After fastboot reboot i am not able to enter recovery mode by holding volume up/down button+power button……help pls
hi! First of, tnx for the instruction. I totally blame myself for not getting it done right 😉 So I’ve just reached up to step XX, only to not get into recovery mode. My fingers are sore from pushing buttons, my nails have split and my headache is getting worse… I’ve tried your suggestion in cmd “adb reboot recovery”, but all I get is “device not found” and my phone is in a continues loop, just the Sony logo on and off. It’s just an old phone I use as a remote, but still… I’d like to get it to work again… I guess I’m screwed? 😉 oh, no leds what so ever and last I checked the battery was up to about 80%…
@vlbuitenkamp:disqus No, you’re not screwed up yet. Flash the stock firmware using this guide: https://techbeasts.com/2014/10/09/how-unroot-restore-stock-firmware-sony-xperia/
recovery your device first and after that we will see what we can do about this custom ROM.
i got some errors while installing the rom from the phone at XXII
where is the fastboot folder?
xperia s lt26i wont boot in flashboot mode, Itried the up button + camera + power and any combination, no reaction. I cannt get any blue light anymore. The disaster begun with the phone suddenly in safe mode and then i realized that the down volume button did not work. Then I tried 3 different sound and volume cards but none helped. I wonder if its life is over. I just wanted to see if I can give it life with a new flash but I cant get in fastboot mode either!
“when giving fastboot flash boot recovery.elf instruction it says phone must be rooted ,but i have already rooted my mobile by using kingo rootapp ‘ ” mobile model is sony experia LT26I ,current version is jelli bean
@disqus_sitBGL6D6J:disqus This ROM requires an unlocked bootloader. Your phone probably doesn’t have an unlocked bootloader. That’s why you’re getting this error.
please send me a link for downloading lt26i 6.0 marshallow zip file free
