[Q] help with sony xperia play r800x

I am new to posting so please bear with me, I recently purchased a sony xperia play r800x from ntelos ( a regional carrier serving western VA) The phone was giving me issues with sluggish performance and randomlyfreezing and rebooting ntelos warranty would not exchange the phone because they said it was a "known issue" so ithought maybe it was a memory issue the phone has a lot of preloaded games you cannot remove, so i rooted the phone and attempted to remove a game using titanium backup which case my phone powered off and was stuck at the "sony ericsson" screen i attempted to reload a firmware using wotan client but now my phone has averizon firmware and i cannot get any service is there anyway to get my ntelos firmware back on my phone? i have looked everywhere and i am at my wits end please help

Help:
1. Install Android SDK and ADB drivers on your PC
2. Install SE (Sony Ericsson) FlashTool.
3. Download r800x ftf original rom file and put it in firmware file in flashtool
4. put your phone in USB Debugging, and use flashtool (click the lightning bolt and follow the directions)
fin.
There's threads all over the place that could help, just wanted to make it easy. When you flash the ftf, you will have to reactivate your phone, and the rom will be un-rooted. You can re-root using zergrush on flashtool.
Best of luck

[Q] Can't find updates for android 4.4.4

Hello. My xperia m2 says that there are no updates and the phone is up to date but it's with android 4.4.2. Theres 1 secound delay in the sound when I play games or use downloaded apps like youtube also the audio doesn't sound very good. To fix that I need to update the android version but I cant. I connected the phone to my computer and updated it with sony PC companion but the version is still 4.4.2. What should I do? I don't want to use flashtools or anything. I think it's the phone's fault for that and I should give it back to the place where I bought it so they can fix that. The phone is brand new and they already changed my camera because it wasn't working. So what should I do?

I suppose it has to do with the Country of your phone and/or if it is branded. IF after using PC Companion it's still with 4.4.2 I'm afraid your best (and only) option is to use Flashtool. Not sure how it works if it is branded though, you may need to to something to be able to de-brand it.
Well, actually try first to check if 4.4.4 is available in this way:
- Dial *#*#7378423#*#* (*#*#service#*#*)
- Check the number in Service Info/SW Info/Customization version. You just need the xxxx-yyyy part
- Downdload and install Flashtool (it's small. You just need it for checking)
- Run Flashtool
- Go to Devices/Check Updates
- Select your phone double clicking on the id xxxx-yyyy you have got before.
- If the version is 18.3.C (like the one for 3 UK) there is no 4.4.4. the latest ROM is 4.4.2. It must be 18.3.1.C for 4.4.4

My is branded from T-mobile, and i flashed CE ftf to debrande, everything is good except i don't have extra apps that T-mobile puts in. As i know your safe flashing ftf cos it's official Sony's software, just using Flashtool instead of PC Companion and you won't lose warranty, as long as you don't unlock bootloader.
Good Luck.
Xperia M2 D2303 on K.K. 4.4.4

Do I install the flashtool on my computer or on my phone?

Click to expand...
Click to collapse
Obviously on the computer. It's needed to flash the phones from it. Just google it, you find it immediately. Then if you decide to flash a generic 4.4.4 FTF just search around. There are dozens of guides in the Internet.

Alright thanks for your support guys

A few problems - IMEI, Rom, Root, recovery

Hi I succesfully flashed my brother in laws Lenovo A369i with the latest firmware Lenovo_A369i_4.2.2_(by_xdafirmware.com).zip found at http://firmwarefile.com/lenovo-a369i
I followed this guide and used the flash tool included in the firmware package above, and the latest usb drivers from below:
http://www.modifyandroid.com/stock-roms/lenovo/how-to-install-stock-rom-in-lenovo-a369i/
https://androidmtk.com/download-lenovo-usb-drivers
According to the phone, this version is A369I_S110_140108 - and when checking for updates it says that this is the latest one - but how can I be sure?
I searched on google and most of the times there are sites that claim to have the latest but they don't write which version it is(very anoying) so I can spend many hours(very slow internet connection) on downloading the one I already have or one older.
The information and guides on here Xda has not been updated for a while.
The Phone works with both phone calls and sms, but the IMEI is not written - so should I do that with SN_Write_Tool_v2.1504.00.zip, MTK Droid Tools or is there an easier way to do it - or should I just forget about it?
UPDATE: I got this sorted out now, by rooting with framaroot and using Chamelephon to first make random IMEI then reboot and change the IMEI to the correct ones.
-----------------------------------------------------------------------------------------------------------
My second problem is that the phone were unlocked before I flashed it and now its locked again - are there a guide to unlock it?
The phone were not bought with subscription, we bought it here in the philippines from Lenovo Mobile( not real Lenovo company but dealer/importer allowed to use the name(for god sake stay away from them)) and after repair the dealer sent back different older model(this A369i) with less battery and locked to Globe. After trying for 2 months to get them to give us the unlock code, I gave up fighting them and had it unlocked at phone repair shop were they had to use a box to do it, so I never got any code.
---------------------------------------
Third problem: I need to root it but not sure which tool to use?
Update: This is sorted out, see above.
--------------------------------------------------------------------------
Fourth problem: I like to install custom recovery on it - but which one work best and allow to flash from SD card?
As this is the first time I have flashed an Mediatek phone, are there anything else that I need to do?
Hope an expert can help me

Trick or hack Xperia Companion into using other firmware files when Repairing phone?

Im wondering if anyone has tried to use Xperia Companion (XC) to install firmware other than the latest available. XC uses firmware files located in the ...UpdateEngine\localstorage\US\ folder, so i thought i could swap them with files downloaded from Xperifirm. I even renamed Android12 binary files with Android11 filenames, but appears XC is too smart for me. Trying to Repair offline doesn't work either.
I ask because im now on Android12 and would like to go back to Android11, but im having no luck. Flashtool comes up with errors, Newflasher gives me the "Your device is corrupted" warning.
I'll get there eventually, i hope.

From what I understand you'd have to do a clean install and also unlock bootloader once you go up an Android level you can go back sorry I can't help you
