I run a stock Uk firmware which is prerooted and have NDR utils recovery, bootloader is locked, I want to get back to Egyptian or global firmware of stock and unroot so I can take to recovery as the phone has not been very responsive, thanks

Download the Egyptian rom using xperifirm. Then flash it by flashtool and full wipe.

Use PcCompanion -> Repair. Stock original firm will be flashed to the phone. All your data will be lost. The best way before SAT.

[Q] Rooted phone gets stuck at SE logo

I just rooted my phone using this method, which has been succesful for me earlier.
Everything went fine, and I didn't do anything except for what stated in the post, but when I tried to startup the phone, it gets stuck at the SE logo. Not the text logo, but the logo after the colorfull animation and with the picture logo above of it.
I removed the battery after waiting 10 minutes and I tried again, with the same 'result' (or failure as you wish).
And, yes, I have used the Neo file, not the Arc's. My Neo was running on the latest 4.0.xxxx firmware before rooting.
Should I try:
reflash ROM?
relock bootloader?
flash another ROM
????
Edit:
When charging, the phone also won't get past the green logo, and the LED is not on.
Edit²:
Fastboot mode working, so flashmode if necessary also I guess.
Now retrying from the neo_modded.img
Edit³:
Didn't work, now reflashing stock 2.3.2
Reflash 2.3.2, root with Gingerbreak and update OTA to last 2.3.3
FIXED
now on stock 2.3.2
But, this is XDA, so let's try to flash a pre rooted ROM I just finished downloading.
Hello,
With an unlocked bootlaoder you can flash the 2.3.3 firmware, then install DooMKernel from recovery . That seems Root, Recovery and an Overclock option with the latest stock rom
Phone is working, now checking if rooted.
It was quite easy actually:
flash generic 2.3.3 with flashtool
turn on USB debugging and select device Xperia X10 in the flashtool
in the top menu, click root psneuter
turn phone of, and flash relock bootloader Xperia
update your phone to 2.3.3 using PC companion or SEUS
Hmmm, sure this worked for me once, phone now won't get past a black screen witch lit background, flashmode working. I'll retry.
Fixed, but phone not rooted. I'll leave it this way, non-rooted.
Unlock bootloader. Flash 2.3.4. Flash rootxperia and u got the latest with root. No overclock yet for 2.3.4 but it's all good.

Which firmware version?
Best is to reflash everything and wipe your phone during the process.
Download the X10 flashtool.
I'd recommend this method (only if you have an unlocked bootloader) it's very easy.
here are some additional instructions considering flashtool

Hello All
This is a guide to install the latest version of Android 2.3.4 - MT15i 4.0.1.A.0.283 Global on your NEO and install root access.

1. Backup your data. (Just in case!)
2. Download the FTF file from here:
http://www.multiupload.com/DGV8GLT1TP
(Thanks to sdk16420 for uploading the update files and thomasafca for making the FTF and uploading!)
3. Flash the FTF file with Flashtool. Unselect 'wipe user data' to preserve data and settings. (You can get flashtool from here (http://forum.xda-developers.com/showthread.php?t=1000012)

Good luck!
I don't know what firmware, i just know that it's a MT15a...
Which firmware should i use?
I just flashed with the latest 2.3.4 firmware and it's working.
Now i would like to know what tutorial to follow to root my phone with this firmware and don't brick it.
Also, I unlocked bootloader before i flashed, so i don't know, it's still unlocked?

yes, it should be still unlocked.
One : since you unlocked your bootloader, some music add-ons in the stock player won't work anymore, same for TrackID. Replacement for TrackID is Shazam.
Two : DO NOT accept over the air updates, only update using PC companion or Update service on your pc, else your phone will be unusable.
So, here's how to root 2.3.4. It's very easy if you know how to flash.
All your data will be saved, but best is to make a backup just for sure.
Note: just copy the zip to your sd card (when I tried it first, I unzipped it. Had no experience with clockworkmod)
Good luck!
I'm having the same problem. I'm on 2.3.3, unlocked the bootloader, and then flashed rom from http://forum.xda-developers.com/showthread.php?t=1281489. What should I do?
Flash back to stock 2.3.3

I had it too, you can't do anything about it, except cyanogenmod.
Thats my expericence

yes all data is lost,there is now way to get back after reflashing new software.
yeah.. already do that -.-'
What? CWM keeps data in SDcard, its not lost at all. But if you use SEUS, it will probably upgrade do .62 firmware, wich can't be rooted yet. You still have lots of options (flash back to .58 using whatever you like, wotan, flashtool) or unlock bootloader and flash a kernel with CWM builtin.

flash kernel with in-built CWM and restore, if it didn't work then flash ROM again, go to CWM -> backup and restore -> advanced restore -> choose backup file -> restore data. thats it, your apps will be back.

maybe. but before you unlock bootloader, flash stock kernel and rom via flashtool. you don't need unlocked bootloader to flash stock kernel. then root phone. install CWM and restore data. all apps will be back.

[q] really really noob question here!

I have a Wt19i with rooted 0.62 stock rom with cwm recovery installed but bootloader is locked. I recently changed the status bar with cwm but i hated it so i want to flash it back but i forgot to make a backup so I want to flash 0.58 again and root it then update it via OTA.
Will the cwm be removed?
Is it bad with locked bootloader with cwm?
Will i use flashtool/seus/pc companion or cwm itself to flash it?
Will it have problems like bootloop or even bricking my phone?

use flashtool to flash .58 stock rom then root then update via OTA again.
CWM will be removed in the process.

thanks for answering my questions
Can i be sure there will be no boot problems?
i dont think there would be boot problems,
just make sure to wipe dalvik cache and delete all data for a clean install of .58 fw.

Yes, CWM will be removed.
Locked bootloader does not affect CWM at all. You need to unlock only if you want to install custom kernel and/or ROM.
To flash stock firmware, you can use SEUS, Flashtool or Wotanserver.
Chance for a bootloop or bricking is quite low on Android Xperia phones. Although there is chance for some bugs, if you install incorrect firmware via Flashtool.

Revert to Stock Rom using TWRP?

So I have a Galaxy S3 i747(at&t) rooted and with an unlocked bootloader. Currently running Cyanogenmod with TWRP recovery.
I'm trying to downgrade back to Touchwiz for the purposes of using an unlock code that AT&T provided me with (apparently it doesn't work with AOSP roms). Any chance I could safely use TWRP to flash the stock rom, and then use TWRP to flash Cyanogenmod back right after?
I've read from here and there that flashing the stock room with an unlocked bootloader and/or flashing the stock room NOT using Odin could brick the phone, etc etc.
Sorry if this question has been answered quite a few times, I've seen quite a few different answers regarding this floating around.
Cheers
You must flash stock ROM via Odin
After root again and flash custom recovery

Guess there is no way to NOT use Odin :/
Do I have to relock the bootloader/unroot the phone before I flash with Odin? Also, will it put the phone back to Stock Recovery or can I keep TWRP?
And one last thing before I go through with this...
http://forum.xda-developers.com/showthread.php?t=2388065
Is this^ a possible way to go back to stock without going through Odin and losing everything? (Remember, I'm just trying to get to a TW based rom so I can use the unlock code). And if so, can I just flash that rom with TWRP?
I dont think that would be possible. ...u have to use odin
Try and backup your data before u do ..if it helps
Your phone may end up in bootloop if u try with twrp

Via TWRP you are able to flash backup of stock ROM. If you have it

If you have TA backup, you can relock bootloader and make restore from sony comanion on pc. But if you didn't backup TA, then i don't know what to do(
i just repair over PC comparion and twrp gone and all back to stock ( idk if someone in service experts can find that i make custom roms before) but im notice that my recovery dont work, at least when i push vol down and vol up + power
i cant find stock recovery on google im searching for 2 hours
Because any xperias no hasn't stock recovery, this no exist in Sony phones, u only waste time for searching
aham so i cant retrive to full stock all including recovery.... blah, i will send to service and pray that will pass
No, u have only flash stock ftf via flashtool and u have fully stock m4

done but still no recovery, when i set vol + power or (vol+,vol- and power) phone just vibrate every 5 sec.... and thats repeating all the time... screen is off too... but normal power up and flash mode work ok....
Ojoj u don't understand, Sony phones don't have stock recovery at all, only we can install custom recovery on rooted phone or when we have unlocked bootloader, can we flash custom kernels with implemented recovery, but no one make custom kernel jet, only custom kernels are inside in custom roms like cm 12,cm 13
Aham. Sorry... I was found on net "how to enter in recovery mod" that is why i was think that they have recovery
