[Q] Browser issue, Acc linking, USB tethering

Hi guys!
So, I have 3 problems with my new Xperia Arc smartphone :
1. When I turn on USB Tethering on phone, the internet disappears from my PC but I still can't use it on phone. When I try to use Browser it says that there is no internet connection (I did exactly everything what's mentioned on SE website).
BTW, with other phones (HTC Desire S, Desire HD, Sensation) everything worked perfectly.
2. When I turn on WiFi in my phone and try to link my google acc with Xperia Arc, for Market using, it starts loading, but every single time I get error, and it says that my access information is wrong or there's something wrong with settings (advices me to do the Factory Reset or use warranty fixing.
3. When I use default Browser with WiFi and I'm trying to download any apk app or game Browser crashes and I only can Force Close it
Any ideas or advices?
P.S. I don't have WiFi router ant home, so I need to use USB Tethering
P.P.S. Phone is rooted
P.P.P.S. Hope YOU will understand what I said here and Huge Apology for my bad english - Sorry

1. Your english is good.
2. Have you modified your phone in any way? Is it a standard rom, no scripts/build prop edits etc.
3. Any carrier issues re tethering?

Sorry but I don't know how

Ok. Simple things first, have you changed the connection settings on your pc to identify a 3g modem(arc)?
Regarding the market, make sure time&date are correct

Sorry, bit too much whisky last night...
first, check your internet connection on your pc/laptop and ensure it's using the arc as a 3g modem. If no then change settings, if yes then the next step should resolve it;
Your phone is rooted but the bootloader is locked, yes? Flash .42 firmware, using flashtool (If you use pc companion you may flash .58/.62/.69, which can't be rooted yet). Boot phone and retry

[Q] Bootloader Unlock - Driver Problem - Oops

Having a bit of an issue with the bootloader unlock instructions from here:
http://unlockbootloader.sonymobile.com/instructions
Basically the problem is that step 13 just isn't happening. First time I tried it DID pop up but for some reason the bit asking for drivers closed down. Now I can't get to the point where I choose the drivers so I can't go any further.
Anyone know how to fix this?
Thanks!

I don't Understand What do you mean Go to -->Right Click Computer-->Propeties-->Device Manager-->Then Go to "S1 Boot Device"-->Then Right Click on it and Click Driver Something-->Select the Drivers The Drivers for Fastboot never Get Found By windows You'll manually do them on every PC for the first Time!

Thanks! I can't believe Sony didn't put that in their guide. Thought it would be something simple but my last phone I did this on was a Nexus One so i didn't have to do that. Once again thanks! Problem solved.

Then again perhaps there is still a problem...
Did this, went to the right file, the drivers are DEFINITELY here, yet Windows can't find them. WTF Windows?
Oh well, sure its not a huge issue. Any ideas anyone?

Use the latest version of PDAnet. It will solve your driver problems, you won't have to do anything else.

You need some different AMD driver for fastboot to work.
I found the same problem with AMD machine and used a different driver posted by someone on this forum.
Search for it and you will be ok to boot into fastboot once it is properly installed.

I got a similar problem, except that, Device manager does not list S1 Boot device..
But the phone is connected in fastboot mode.. blue led and everything..
the only things listed are:
* Base System Device
* Bluetooth Peripheral Device
* Bluetooth Peripheral Device
* Bluetooth Peripheral Device
* Bluetooth Peripheral Device
* Bluetooth Peripheral Device
But I can eject the device by clicking on the icon in the bottom right.. and that reads "Eject S1Boot Fastboot" ..
but why isnt it listed in device manager?

[Q] Constant crashes/reboots

I have suddenly developed a problem with my DHD. As soon as it connects the network via WCDMA/(3G) it crashes. I can use GSM without any problems. If Mobile data is enable, then that works with 'G' over icon. I have already done a restore to last April and a system reset, but neither made any difference. I have also tried different SIM and SD cards. It started by occasionally crashing with Maps running, and it got quite hot. It would be OK after 4-6 restarts, but now as soon as it tries to connect it crashes.
I am in the UK in SW and mobile coverage is very patchy. There is no 3G at home and only GSM in some rooms.
The phone is unlocked, but with S-on. I have ClockworkMod recovery running, and the system is:
Standard 2.3.5
Kernel 2.6.35.10-g931a37e (Nov 2011)
Sense 3.0
Software 3.12.405.1 with CL199157 release key
Radio 12.65.60.29U_26.14.04.28_M
Any help would be appreciated. I am beggining to think it's a hardware/motherboard problem
Thanks

I think it's a rom problem

I found this thread: http://forum.cyanogenmod.com/topic/50801-random-reboots-2/
It's supposed to be a problem with some version of GB (UK) rom.
If flashing rom, get you the same error you can try use aahk to get S-off on your device, and after that you can flash WWE ROM (it's a standard world wide rom witch allways work the best).
Here's the link of shiped roms: http://www.androidruu.com/?developer=Ace
And if u get s-off you can use this rom: http://forum.xda-developers.com/showthread.php?t=1382235
In first thread that I send you some one said that it can be problem with battery. Try if u have the same problem when you charging it.
P.S.: I have remember now that my friend has the sam problem when he try to use the camera with flash on (even if battery was charged more than half), and when he raplace the battery, everything work fine.

I am a bit confused as I didn't think I needed S-Off to update ROM, provided I manually flashed the boot.img file. I have moved away from AAHK as it is no long supported if you get into trouble.
This problem is curious as it only started a week ago after a trip to Morroco, and curiously there is an identical problem report on the Vodafone forum after a trip to Morroco (see forum-dot-vodafone.co.uk/t5/HTC/WDCMA-Fatal-error-boot-loop/td-p/1605342). No solution though.
I shall have a go at a new ROM, and report the outcome.
Thanks for the help.

If you have stock ROM you can flash it only with stock rom provided with your carrier
With unlocked hboot, with S-off or with goldcard you can flash with other carrier.
In my opinion the best way is always S-off and stock rooted wwe rom.
With this solution when ever you get some problem or birck you can fix it because you have all premissions.
Unlocking hboot with HTC dev is the worst way. People report to many bugs.
About aahk, you can get when ever you want suport for it, here on this forum.
Or you can use AAHK2 by Phiber2000: http://forum.xda-developers.com/showthread.php?t=2367322
Did you try with full battery and mobile phone connected to ac adapter to see if you have the same problem?

This is quick hard work - I have Window 8.1 and I can't get the PC to see the DHD in CMD/Fastboot, so I am a bit stuck. It can't enumerate the device..
HTC Sync works and I have the latest drivers etc. AAHK2 says it can see the DHD whilst it is switched on, but in the bootload, it fails.
I shall have to find a Win7 pc, as it did work when I rooted and unlocked the DHD.

I didn't think this would get so complicated!! I have fired up an old Vista PC, and updated the drivers from the AAHK2 post. They would not install - error reading transform location - so I downloaded the lastest HTC version 4.1.0.1. and used them instead.
I can run 'fastboot getvar all' on a CMD window, no problem, but...... if I try with AAHK2.cmd, it starts, and clears some old stuff, then says, NO phone connected. The phone is in bootloader/fastboot usb mode (in red). I guess its still a driver problem.
This is a dumb question, but I assume the phone should be in Bootloader mode, as I did try the script aahk2.cmd with the phone just running normally, and it did see it and proceeded to the next menu - it suggested option 'h' for HTCDev unlocked phone.

I never use AAHK2.
I only use the AAHK but i think it isn't much difrent.
You can:
when you go in fastboot type: fastboot oem lock
boot in rom
In aahk when you first time download PD98img-GB2.zip it allways stay somwhere in first folder of unziped aahk
after you boot in rom, run aahk2 and if you relocked hboot just press "1" instead of "h".
When I get home I will download AAHK2 and open the script to see what's the difrent's between.

Same Problem!
Hi
I think i have the same problem... I got back from a trip to Morocco last week... my DHD worked fine while over there, but started rebooting as soon as i turned Airplane mode off when landing back in the UK.
It can turn on for periods, and seems very stable when i disable the radio (turning on airplane mode, or removing the SIM). I think it's crashing whenever it searches for a network (regular reboots while driving, but not when sitting at my desk). I can force a reboot by searching for a new network in the settings. Are these symptoms the same as yours?
It's a 3 year old Orange DHD, using the stock build (not rooted yet).
I'd love to know if you get any more clues to your problem.

Hi, and yes pretty much. I have found that if you set the phone to GSM only, it fixes the reboots (as does airplane mode too), and data is still received over 3G if available.
It is very curious about Morocco though. We were in Marrakech for about 5 days, and used the Maps on the phone (offline mode) a lot. I also saw another vodafone report too dated July 2013, so something is happening.
I have now managed to run AAHK2 and rooted and S-Offed the phone, so I shall be trying some other ROMs. I have tried KitKat, but in kept freezing.
Good luck.

Thanks for you patience, I have finally run the AAHK2 script, and after another couple of driver problems, and a failed flash, got it running.
The drivers are different for 2.3.5 vs 2.3.3, so that confused Vista.

Yesterday I stayed long at work so I didn't try anything. Congratulations for success with AAHK2.
If you install kitkat or any other custom rom, before installing you have to do a factory reset from recovery mode, flash new rom, flash boot.img via fastboot: fastboot flash boot boot.img, after that go to recovery mode: factory reset, wipe all cach, wipe dalvik, and everything you can wipe, and reboot.
After that it should work fine. But take in consideration that in all that custom rom always something don't work.
For first testing I suggest that you install stock rooted rom from this thread:
http://forum.xda-developers.com/showthread.php?t=1382235
And in the first post you have as well radio partition. Flash it necessarily.
P.S.: With stock rooted rom, you will not lose S-off, CWM, etc...

Hey guys. I have never been this frustrated in my life.
So, a while ago, I rooted phone and for some reason unlocked bootloader. Everything has worked fine until now, when phone is randomly tapping the screen, and since today it's really warm and draining full battery in an hour or two.
I don't have anything, files and such, left. Also, I can't open Flashtool so my thought to relock bootloader wasn't an option either. I just want to completely erase everything and pick a Sony update for now.
What do I do...? :crying:
I just need Flashtool to start but it won't friggin start. I used it fine before but now it's not reacting when I try.

FT not starting is probably either a temporary server thing, (since it does the whole github, etc. thing at startup), or just an update issue. I've found it pretty smooth and easy to update, if you follow the instructions on homepage. I'm not so sure about PC companion, with unlocked bl and custom ROM, but might be worth a try if it's already set up. Personally, with unlocked bl, I would just use fastboot, flash a custom kernel/recovery, and flash a stock based ROM. The whole thing would be done in less than 10 minutes. Let me know if you don't know how.

Hi,
It may be that your touch screen is dying.
I had smt like this with my z1 as well. it would randomly register touches in the upper area of the screen.
after a few days this area stopped responding to touches completely.
Now the phone it self is usable just a small area on top of the screen is unresponsive to touches, I have to use landscape mode to push some of the buttons.

If you take this option you need to connect the z1c in flash- or fastbootmode.
The last time it did works on my z1c with bootloop after flashing a custom.

You'll need to have a ROM file on your SD card in the phone, so if you can't boot, copy the file onto card w/ PC, then put it in. The above instructions get you into recovery, then you can flash stock ROM. Just pick any prf from the 'general' forum.
As far as FT, I bet an update would fix you. There's been a few recent changes. Check the thread -http://forum.xda-developers.com/showthread.php?t=920746
Note: when you connect in fastboot for the first time, if you're using Windows, you'll get 'installing driver...' If you've been using FT, the driver is already on your computer, so click 'skip Windows update search', and computer should find it.

If you want to just get FT working and use that, go for it. Fastboot is a computer program you can use to flash kernels and recovery, (and for some other stuff). So, if you had an SD card with a stock-based flashable ROM file on it, (any ROM listed as a 'prf' in the 'general' forum), you could put it in the phone, and use fastboot to get recovery, then open recovery and flash your ROM file. Then you'd be back on stock ROM. It's just another option. I guess to re-lock bl, you probably want FT anyway, so just go for that if you want.

Ampull said:
Thanks for the answer. But I can't use Flashtool, I can't open the program itself. I don't know how to fix this or if anyone has a clue why it's doing that. Note, it used to work a few months ago, and I didn't even use it often.

Like I said, you probably need an update. FT homepage has links and instructions for latest update. There's been a few revisions lately. Yo just have to download the latest version, install, then download a patch file and copy it to FT directory, (replacing the one that's there). It probably will work fine then.

I see.. Well that's strange, I've never had it not even start I guess you could try uninstall and reinstall. Have you posted in FT thread? From what I've seen in that thread, Androxyde and others are always quick to help.
Anyway, you can also try the fastboot option...

URGENT - Full and clear instructions to flash stock Sony ROM and bootloader.

I tried installing CM 12.1 nightly on my Sony C2004, but now none of the SIMs are detected!
I decided to take it back to the nearest service center. But they said I have done something against their 'terms of service'. The only option will be to replace the board, which will set me back Rs. 6000 +, for which I can easily get a new Android phone.
I tried using Sony PC Companion, but it fails to detect the phone.
Please provide full detailed steps with relevant links for a newbie in the forum to flash his own phone, which Sony support condemned to the depths of hell. (I could not understand the posts already here that speak of Flashtool.)

Today I realised that not only will this flashing void my warranty, but also will give me the option to throw my phone into the nearby forest :crying:

It worked. Thanks! I rooted the phone using Kingroot, disabled some auto startup entries and now it takes a long time to startup...

Full uninstall King Root, and use towelroot. It's better, and it don't install unnecessary apps, try it and tell me!
Then rooting your phone with towelroot, install Root Uninstaller from PlayStore and use it to uninstall the system apps that u dont need.

The phone never started up. It is hung on the flying ribbons animation. I'm using Sony PC companion to re-flash the firmware.

Try to install CM12 again, it has a custom kernel which able you to modify phone's CPU clocks. It's very useful.
