[Xperia Play Q&A, Help & Troubleshooting] MRCMidnight:
Welcome to the Xperia Play board first of all, I am re-getting the Xperia Play myself after using a Galaxy S2 International myself for six months but I decided to go back to Xperia Play. I'll answer each question one by one and with great detail as I did research long time ago.

1. I am using T-Mobile's $30 5GB 100 minute Unlimited text plan for web activation or Wal-Mart only. I did mines on the web with ease. The difference from the r800i and the r800at is the color shell, software, OS skin and the available radios. I have never got the r800i myself to try the 4G radio before the 1900MHz band was availible this year, if someone else has a r800i then that would be good to have a choice, I honestly do not know about r800i phones. The r800at and r800a both work for T-Mobile's 4G with the 1900MHz band. The difference from the r800at and the r800a model is the bootloaded lock status, the AT is bootloader locked and the A is bootloader unlocked, either phone you get you still need to have SIM unlocked to use the T-Mobile's SIM card and service.

2. The Xperia Play has ICS and JB roms available for download, however installing ICS/JB you will lose some compatibilties in games and a couple of hardware bugs like touchpad not working and camera in some roms. I never used a 4.0+ rom myself as I stayed in GB for gaming and stability.

3. I personally owned and moved from Virgin Mobile AND the Motorola Triumph, I used to have the phone with a low $25 a month and I used customs roms that addresses the hardware issues. The touchscreen in the Xperia Play is better in response and the resolution of 245 ppi and 480x852 is sharp from the Triumph or my Galaxy S2. The height of the screen is the same size to the Triumph, width is less but moving from the Triumph to the Xperia Play is awesome that you do not mind the tiny reduction in width. I never want to go back to candybar phones until the next Xperia Play device comes and I will be a Xperia Playa, this is what you expect once you hold this device in your hands! :good::laugh:
[Xperia Play Q&A, Help & Troubleshooting] fishvtt:
Thanks a lot for the reply! That was very informative.

Which phone do you have, R800a or at? I know it doesn't matter, but I'd rather have the confidence that someone else has gotten it working on the specific phone.

And alright, that sounds good. I'll use the GB roms then. Hopefully my transition from Jellybean down isn't too much of a problem.

Wow, it looks like there is a ton of people like me. I had the Virgin Mobile 25 dollar plan before switching to T-Mobile too, and I actually have the 5gb plan right now.

Thanks a lot for your help again! Hopefully I'll turn into a Xperia playa too.
[Xperia Play Q&A, Help & Troubleshooting] MRCMidnight:
I had the r800a the first time, that got stolen, then the r8000at the second time which broken. The next Xperia Play phone is going to be a

r800at

because to me has a better OEM feel and it was made for the US market and if you get the AT&T box in either new or like new condition, you get extra accessories like the dock (if sealed). JellyBean is a cool feel on my Galalxy S2 but I will not miss it as much as I plan to flash Gin2JB v2.3+ rom in the future, my Xperia phone is coming later this month as I still am in the game, lol.

T-Mobile's 5GB 4G is better than Virgin Mobile's 2.5GB 3G data, especially here in the San Francisco Bay Area. Your location varies in signal strength. I promise you, if you like retro games and like to play games on a gamepad, you will never come back to candybar phones. Here is one more important thing you must know, be gentle when you slide the screen up and down, the flex cable is the weakest link and can kill the phone from screen and device and never place paper or fragments in between (that is how my second phone failed.)

You are welcome fishvtt, I am more confident on a r800at like I said because of the parts but also for the fluidity of the feel and performance of the networks and functions, might be placebo but I honesty like the r800at more, either one is fine, each one is the same to support anything from roms, kernels and firmware, it is all GSM compatible and universal when used with custom recovery. ;)
[Xperia Play Q&A, Help & Troubleshooting] fishvtt:
Thanks a lot for the help. And I'll keep that tip in mind. (To take care of the flex cables).

I'm probably gonna be scourging around ebay for the next couple of days and I'll keep it in mind to look for the AT version.

Already getting hyped up, can't wait to relive the nostalgia of having a gameboy :p
[Xperia Play Q&A, Help & Troubleshooting] MRCMidnight:
Awesome, well I have a merchant on Amazon who will send me a

like-new

Xperia Play, in the description it it said it was unlocked and tested with a 30 day money back warranty. I will let you know once it arrives on Monday or Saturday if I am lucky. I got it at 119.95 with FREE shipping: http://www.amazon.com/s/ref=nb_sb_noss?url=me%3DA1KSB2QN4L6U9U&field-keywords=xperia+play. Best to wait and give you the green light when I receive it from said merchant. :cool:
[Xperia Play Q&A, Help & Troubleshooting] fishvtt:
Wow that price is amazing.

Well sounds good!

Be sure to keep me updated!
[Xperia Play Q&A, Help & Troubleshooting] MRCMidnight:
Will do, I am also waiting on some accessories which I will review in the future as I do not see them on YouTube or other sites. Which ever comes I will post it in their respective places/topics. :cool:
[Xperia Play Q&A, Help & Troubleshooting] MRCMidnight:
Just an update. I got the Like New Xperia Play r800at in the mail today. The phone is a r800at with the phone, battery, and standard charger (AC to micro USB). When I inserted the T-Mobile SIM card it is unlocked, however I cannot enter fastboot mode and I have to pay alejandrissimo to get my phone fully unlocked. 360 Mobile Solutions, the seller who sold me the phone for $119.95, sold me a great looking phone, no damage at a quick other than the area around the USB port, it's okay with me; also the screen still has the factory sticker "TXTING & DRIVNG ... IT CAN WAIT" on the phone, which is excellent. I say buy from them, save yourself some money for a nice case and other goodies. :good:
[Xperia Play Q&A, Help & Troubleshooting] fishvtt:
Sweet! Was waiting for the response. That's good to hear. And just to make sure, the 4g HSPA+ does work right?

I'll be ordering from them then. Thanks a lot for the response man. You've been a great help!
[Xperia Play Q&A, Help & Troubleshooting] MRCMidnight:
Yes, this phone does work for 4G HPSA+ on T-Mobile. Thank you for the sticking around, let me know if you want to hear more about the phone and it's features. :good:
[Xperia Play Q&A, Help & Troubleshooting] fishvtt:
Awesome man! Thanks a lot. Don't have any questions right now, but If any do come up in the future, I'll be sure to ask you.
[AT&T HTC One (M7)] Rogue Leader:
A superuser popup came up for "Reset Notify" app and I accidentally clicked the bottom selection of "deny permanently". In SU 1.0.1.8 there is no option to undo this or change it. How can go back and allow it?
[AT&T HTC One (M7)] gunnyman:
Clear data for supersu
[AT&T HTC One (M7)] _MetalHead_:
That reset notify thing pops up quite frequently for me, it's kind of annoying. Mr. Gunnyman, any idea what it is?
[AT&T HTC One (M7)] Rogue Leader:
Tried to do that but the clear data button is greyed out, there is no data
[AT&T HTC One (M7)] gunnyman:
No idea what it is metal dude
[AT&T HTC One (M7)] _MetalHead_:
com.htc.resetnotify. You'd think that granting it permissions once would be enough but noooooo it would rather pester and annoy me every couple days. Google provides zero answers.
[AT&T HTC One (M7)] gunnyman:
My stock rooted phone never sees this
[AT&T HTC One (M7)] _MetalHead_:
Mine is stock rooted too. I saw it on my last one with cleanROM as well. It really isn't that big of a nuisance, I'd still like to know what the hell it is though. What superuser app are you using?
[AT&T HTC One (M7)] Rogue Leader:
It doesn't seem to affect anything so far with it denied permission.... I'm just worried its needed for something....

That and I would just like to know for the future in case i make this mistake again.

My phone is stock rooted, heck I just got it yesterday....
[AT&T HTC One (M7)] _MetalHead_:
I just froze it in TiB. No negative effects.
[AT&T HTC One (M7)] cschmitt:
I think it's somehow tied to the HTC Setup app that prompts to setup an HTC account. I've seen the reset notify prompt at the same time the green HTC notification. Just froze both.
[General Questions and Answers] I.nfraR.ed:
Hello,

I was trying to port Android 4.2.2 from A83o to A820, which has 4.1.2.

While flashing the files through FlashTool the electricity was cut off. I'm not quite sure which image have been processed the moment of power loss.

when the electricity was back on, I reflashed the stock ROM via FlashTools. Phone turns on and boots into OS, but touchscreen is completely messed up - Top part is bottom now (sligtly misaligned though) and left parts are corresponding to right touch points.

So e.g if I want to tap on the bottom of the screen, I need to touch the display somewhere in the middle of the top half.

It's awful to navigate, but managed to do a factory reset. Not that helped with anything.

I've tried all official versions + my modded roms + restore from recovery. Everything works except touchscreen.

Is there a way to bring back calibration data? Factory menu (volume up + power) is in chinese, but also responds to up and down keys only and I can't select any item with power button.

I can tell people how to dump any block with FlashTool ReadBack option (will give them instructions and so on), but would it be of any help?

PS: Oh, IMEI is not there either, so it seems everything got erased somehow. Not sure where calibration data is stored, but I guess it's on a separate nand flash.

If I flash nvram block frm other A820, will it fix the problem?
[General Questions and Answers] I.nfraR.ed:
I pulled nvram folder with adb and there is /md/NVRAM/CALIBRAT folder inside with many files.

Do I need to replace all of them in order to get it working?

If I get the touchscreen working, then I will fix IMEI and WIFI mac address.

Doesn't help at all. Hardware problem due to power shutdown during the flashing process?
[General Questions and Answers] raphaelmattioli:
Same problem

I have the same problem on my lenovo a820t. I did a factory reset and still the touch screen is all messy. Did you solve the problem already?
[General Questions and Answers] I.nfraR.ed:
No, I've ordered a new touchscreen, but they sent me the wrong one, so now I'll be waiting another 2 weeks for the correct one :rolleyes:
[General Questions and Answers] Jandruss:
same problem

I have the same problem, lenovo a820t , can anyone help us??
[General Questions and Answers] goasutlor:
Any update for this touchscreen issue. Cause i just face this problem also so i think it might be HW problem.

Please recommend me the site that you order the touchscreen cause i have to order too.
[General Questions and Answers] I.nfraR.ed:
Haven't received my touchscreen yet. It's taking so long...

Still nothing in the BG Post tracking system, which means it has not arrived in Bulgaria yet.

I will report if that fixes the problem as soon as I change it.

I've ordered it from aliexpress, but can't recommend a seller, since I haven't got anything yet, except a wrong touchscreen once, that I had to return and after that they sent me a new one (at least that's what they say). If you decide to order one, make the seller measure it first, so you're sure it fits.
[General Questions and Answers] I.nfraR.ed:
Ok, got another wrong touchscreen from a different seller. And I asked them to measure it first.

They said it's the same, but I'm sure they didn't measure it.

It's one month and a half since I'm not able to use my phone, because of the Chinese sellers.

Now really don't know where I can get a correct one.

There's one seller that seems to sell the one I need, but who knows...
[General Questions and Answers] I.nfraR.ed:
Issue solved, here's how:

This guide applies to A820 only, for A820T you need the first firmware, flashtools and drivers - nothing else.

You also don't need to replace anything, just flash the special A820T firmware and you should be ready to go.

What you need:

1. Special A820T firmware, taken from lenovohome Chinese forum: http://d-h.st/HdW – I have uploaded it in my dev-host folder and removed password protection.

2. Any official A820 firmware, I have used S139 from needrom site: http://www.needrom.com/mobile/lenovo-a820-11/

3. FlashTools - the version included in A820T firmware

4. Ofcourse you need MTK drivers, but if you have flashed the wrong firmware first, then you should have them installed.

- Extract all archives into separate folders

- Load A820T scatter file in FlashTools, turn off the phone and leave battery in. Remove all SIM and external SD cards just for safety.

Now click on preloader (not on the checkbox, but on the name inside FlashTools) and a prompt will pop up.

Select the preloader from A820_S139 firmware (or from the version you chose on step 2). This step is necessary, because phone doesn't start with preloader from A820T.

Alternatively you can replace the preloader inside the A820T firmware folder.

Then hit Firmware->Upgrade and connect the phone to PC.

- After you see the green circle, try to power up the phone. I have tried it on two A820 phones. One of them booted into OS, the other one was stuck at Lenovo logo, but both worked after next step.

- Now turn off the phone again, load scatter file from A820_S139 (or from the version you chose on step 2) and flash the full firmware with Firmware->Upgrade. After that touchscreen should work normally.

Thanks to lenovohome Chinese forums and Russian lenovo-forums.ru. This wouldn't be possible without them.

Note: As I understood from other users, replacing the touchscreen also fixes the problem, so it seems the original assumption that something happens with the controller/drivers is correct.

However I can't explain why and what exactly goes wrong.
[General Questions and Answers] Jandruss:
Hello I.nfraR.ed from Spain, and many many thanks a lot I have repair my A820T touch problems, now can I flash a A820 rom without problems ? this is for spanish language.

Thanks in advance
[General Questions and Answers] I.nfraR.ed:
No, it just repairs the touchscreen problem. If you flash A820 rom, same will happen.

A820, A820T and A830 firmwares are incompatible. Well, not sure about A820T <-> A830, but both are incompatible with A820.
[General Questions and Answers] Jandruss:
hello again, now I'm setting the phone and have two sims installed, I have de miui a820t installed with morelocale2, all it's ok but the first sim didn't works cause invalid imei apeears, what can I do to repair it ?

---------- Post added 29th June 2013 at 12:16 AM ---------- Previous post was 28th June 2013 at 11:29 PM ----------

now I have tried to do a voice call and always call ended , what's happened ?
[General Questions and Answers] I.nfraR.ed:
Have you accidentally formatted the nand flash?

Flashing this firmware should not cause such issues. Tried on 2 A820 and everything is fine.

Search for guides for restoring IMEI numbers, there are plenty of these.
[General Questions and Answers] Jandruss:
I have tried the replace of MP0B_001 file but again the invalid imei message appears, how can I restore on this model ??
[General Questions and Answers] I.nfraR.ed:
Use the method from post #5: http://xdaforums.com/showthread.php?t=2197378

There are some other methods which are permanent, but you can try this first, should work fine if your phone is rooted.

You can get your first IMEI from the sticker in battery compartment, but I don't know how to determine second IMEI without backup. Do you have one?
[General Questions and Answers] Jandruss:
Hello again, I have write IMEIS ,back again and now I can do voice calls, this is ok, but the cell can't work 3g networks, any company, I have tried every thing, mobile uncle tools 3 roms from need rom, APNS are ok configured, any ideas ?
[General Questions and Answers] sgjol2yt:
Same issue with A830

I am also having the same problem with my A830. I think it lost IMEI when I did a full format using Flash Tools v3.1304.0.119. Tried restoring with all 5 solutions cybermaus posted without success. MTK tools show both IMEis that I have restored but phone will not connect. Once it actually worked, I could receive/make calls but it got blocked again within 1 hour.

I flashed another A830 with the same firmware and didn't have these problems. Have also tried several different firmware, but no success.

Very frustrated. Please heeeeelp!
[General Questions and Answers] I.nfraR.ed:
Well, I don't say that flashing a new firmware is 100% safe, sure there is a risk. But it's highly unlikely (if the ROM has correct structure) flashing an official ROM ruins your nvram block. I've flashed offical firmwares for A820 numerous times and I never had such issues.

The problem in your case is called "full nand format from Flash Tools". If you do this, then all is lost and there's only one way I know to permanently restore IMEI's, BT and MAC address. However, I won't post such information here.

I can try to help people on PM, but be sure I'll never post it on the forum.

Hi, I have a similar problem with my Lenovo A820, but it has started without any firmware upgrade or anything I did myself....

I have an area (around the lower third of the screen) wich has erratic behavior : 80% of the time everything is ok, but 20% of the time, doesn't recognize some actions, in particular tap and drag .....

I have followed the Infrared tutorial, but the problem persist. Again, I don't think it's a hardware failure because it's not permanent, but it doesn't seem to have anything to do with the rom installed.

Yep, i have this same problem. My touchscreen sometimes isn't responding in strip located in first line of characters (QWERTY in vertical orientation) Android Keyboard. I just cant figure out what type of problem is this. As you said, only 20% of time issue persist, more often its just working. If anybody is interested, i can make a video with issue.

Touchcreen problem

I have a similar touchscreen problem, since I installed lammbda 2.3.5a, sometimes, the screen becomes inacurate, especially the lower half, about 10 pixels fluctuations. This is not constant, it does not happend always, it comes and goes away as it pleases. I tried Infrared's guide for touchscreen fix, and it seems to work at first, but appears again
[General Questions and Answers] puradawid:
This same here (i think it is lambda caused problem). Now i upgraded my phone to S150 kernel and install Cappa's ROM. If i get same problem here, i will edit this post. For now it looks OK.

Edit:

Still same. First line of keyboard in vertical orientation isn't working sometimes. It's freaks me out. Is someone fix this problem?

Hey, thanks for posting. I have tried many things, including reflashing original nvram, all touchscreen fixes, posted by Infrared and others, flased back stock ROM many times, tried many ROMS, now I'm using 2.4 lambda, nothing worked for me. When I unlock the phone it works good, but after a while ( sometimes minutes, sometimes more) of usage it begins to loose accuracy. If I lock it, leave a few seconds then unlock it, it works good again. I guess this is it, it doesn't seem to go worse, it is still a usable phone. I'm curious if touchscreen replacement would fix this issue.

If anyone could suggest a fix I would be willing to try it, assuming it is something that can be undone
