Reviving from Android 2.3.4 - Xperia Arc Q&A, Help & Troubleshooting

As a backup phone I have my old Xperia Arc LT15i with Android 2.3.4 and would like to use it. I would like to install Google Keep but each time I go to the Play Store it doesn't look right and says no internet. I have root.
How can I get a bit more life coming from such an old firmware? I already have root. The boot loader can't be unlocked.

Hey,try updating to the latest stock rom which is 4.0.4 ics using flashtool you can find them somewhere on this forum goodluck

For the "no internet" problem, if you have an unlocked bootloader it might be worth flashing CM7 if you want to still be on 2.3. However if you don't, I suggest you do a reset (Settings > Privacy > Factory data reset) (or if you want you can even re-flash with Flashtool and root again) and try again.
However, you won't be able to install Google Keep because it requires Android 4.0 or higher. You can upgrade (but I wouldn't suggest you to do so unless you really need Keep, 4.0 is really slow on the Arc) using Flashtool with this file. You can find many tutorials on how to use Flashtool online.

[Q] Unlocking bootloader Xperia Play question

I bought a few weeks ago an Xperia Play locked on the 3 Network of UK. I removed the sim locked through one of the many sites that offer this service (htccode to be exact) and debranded it through wotanserver.com.
The problem I have is that I tried unlocking the bootlader of the device to no avail since I just can't enter fastboot mode no matter how many times I try (the blue light just doesn't light up). I've read quite a few other posts on this forum and a few other sites but I just can't find a clear answer as to why this is happening. I mean I unlocked the sim lock, I changed the firmware with a "clean one" and still it refuses to enter fastboot mode.
I tried rooting my phone through Gingerbreak or Superoneclick but they didn't work either. Is there any method (preferably an easy one) to root my phone? It's on Android 2.3.3.
Just a quick update to inform you that after a little more tinkering I managed to root my phone, and I might as well share with you how I did it.
Basically again using the wotanclient I returned my FW to 2.3.2 and tried Gingerbreak again. This time it worked like a charm! I also discovered that in 2.3.2 the 3g that didn't work on 2.3.3 now works like a charm so I might stuck with this FW for a while longer (maybe I will try 2.3.4 at some point as well).
Your bootloader is locked by your provider and it won't help unlocking the sim nor debrand it with flashing another FW. That's why it didn't help doing the stuff you did.
Look at this thread for unlocking the bootloader and accessing fastboot (it'll cost some money though, not much afaik):
http://forum.xda-developers.com/showthread.php?t=1232050
Further more gingerbreak/superoneclick etc. only works on gingerbread 2.3.2 as the loophole got patched in the higher builds. So if you want to retain root when updating do it by OTA or if you get fastboot going you can do it via CWM (clockworkmod) with a flashable .zip.

or you can flash doomkernel (which has many advantages, but again, need to enable fastboot mode on your phone, to then unlock bootloader before you can flash the kernel)
i highly recomend using alejandrissimo's service. i did, and i've never looked back

Yes there is mate. I take you have a R800i.
Go to the dev section and find a FTF file of FW build 2.3.2. Then grab flashtool 0.2.9.1 beta. Flash the FTF file and there you go. Downgraded and ready to root.
There's an easier way to root now, i take that's why you want to downgrade, just use the zergRush to do it. That works on any FW build. Check out the dev section for a thread about 'rooting with zergRush'.
Regards Dousan...
I forgot about the zergRush post cuz I bookmarked it but didn't read it that well. Are their bugs for doing it on the higher fw tho?

[Q] Xperia Pro MK16a / MK16i firmware

Does anyone have a copy of the stock firmware from the Xperia Pro MK16a or MK16i.
I messed up the phone and want to re-flash the stock firmware back into my phone.
I dont know what else to do and I am desperate....
If you have it in ftf it would be great. Please put it up on mediafire to share.
THANKS!!!
First, it should be usefull to know what you did to brick your phone.
Thinking quickly, here are your options:
1. If you damaged the system partition(mtd0), you may restore it with fastboot having a stock one. Also, it may be possible to restore it with from ClockWorkMod recovery(started via fastboot), with an update created from the stock firmware.
2. If you accidentally damaged the kernel, that would be a bit more difficult. Currently, there's no custom kernle for MK16, so you would have to wait until there's one, or recompile the stock kernel from source(SE makes sources available).
If it's the first, I may be able to help you providing my system partition. It's not the stock one, because the first thing I did when I got to root my phone was start Titanium Backup and begin to delete some system applications I considered useless. But I think you could find my system partition useful. Just explain a little more what you did.
Thanks for trying to help.
Basically I flashed another firmware for it and it didnt go as expected.
I cant restore it because now my phone is recognize as another phone so i cant download the stock firmware for my phone via PC Companion.
Mine is a MK16a with all the bloatware from fido.
I dont really care about rooting it or not.
I just wanted to get raid of some of the stock apps so it doesnt take up so much internal memory.
I think what I really need is the stock MK16i firmware and flash it to my phone or if someone got the stock MK16a firmware I can flash it again to get it running again.
If you anyone have any other suggestions please let me know.
Thanks
i also need a mk16i firmware packed as ftf, can someone help?
TeamXperia has MK16's now, so a stock firmware should be coming pretty fast from them.
I think ftf is for kernel & loader, not for system partition....
ichidakira, I managed to make a dump of my system partition, I think that will fix your phone. Note that it's not the original system partition, as I've deleted some of the default apps and changed the bootanimation.
To restore it in your device, follow this steps:
WARNING: This will clear all your data, including (but not only limited to) contacts, sms, applications, configurations, etc.
1. Download & extract this file: http://soporte.opensysperu.com/downloads/system.zip & the Xperia Pro recovery image from FreeXperia Project: http://www.megaupload.com/?d=8L3DC0UQ .
2. Copy the system.img to your sdcard(using any method).
2. With the phone turned off, hold the menu button and connect the USB cable. If windows asks you to install the driver, do it as specified in the thread about rooting Xperia Pro.
3. Open a command prompt on the folder where you have downloaded recovery.img .
4. Run "fastboot boot recovery.img"
5. The phone will turn on and get detected as a ADB device. Also, the CWM menu will appear on the screen, but you will not need it for now.
6. Run "adb shell". Then, run the following commands: (It may take a few minutes)
cat /sdcard/system.img > /dev/mtd/mtd0
exit
7. On the CWM menu, use thew Vol Down key to highlight "Wipe data/factory reset", and then press the power button. Confirm the action if needed.
8. When finished, type "adb reboot" on your command prompt.
Then, your phone should boot normally.

MK16i system partition
Guys, could anyone provide me stock or at least his semi-stock system partition, as alvaroag did above? I have rooted xperia pro MK16i (via xperia recovery) and I'm experiencing weird problems after hard reseting my phone. Everything works virtually fine now, but:
- home button works, but doesn't act as home should
- after USB connecting to PC the PC says that my SD card is not inserted (however I can see its content while in the phone)
- PC Companion software can't find the phone
If anyone would have any advice how to solve this, it would be much appreciated also.
Edit: I had rooted this phone month ago and until yesterday there were zero problems. But then suddenly I lost some of my synced contacts from MS Exchange, so I decided to hard reset it and reinstall apps to fix this little issus. And then everything started...
Try with the latest SE firmware:
{PRO}[DEVELOPMENT] - CM7.2.0 - FXP047 FreeXperia Project
At the bottom of the post are the links for the MK16i SEMC 4.0.2.A.0.42 & MK16a SEMC 4.0.2.A.0.42. Select the one according to your device. Flash them with FlashTool. No this will permanently erase all of your user data.
Then, if you want to root it, try with the zergRush exploit: [16/Nov][ROOTING/UNROOTING] Xperia 2011 Easy Rooting Toolkit [v3.0](zergRush Exploit)
If the phone still presents problems, reflash the stock firmware & take it to your service provider for warranty.
Thanks, alvaroag. I was fixing further and further on and ended up with reflashing Jozinek's stock firmware which solved everything. But then, even with virtually out-of-the-box phone, SEUS still denied to update firmware, saying that the phone has altered software. Not sure if anybody really tried to wipe out EVERYTHING from the phone and pretend, that it hasn't ever been rooted or hasn't been did anything else, but I doubt SE repair service can be fooled that much - even stupid updater still sees some difference between my phone (which obviously lost all changes I made to keyboard, root access, everything after successfull revert to stock firmware provided by Jozinek) and regular not altered phone. So to make the story short - now everything works fine, I have virtually brand new phone, rooted via [16/Nov][ROOTING/UNROOTING] DooMLoRD's Easy Rooting Toolkit [v3.0](zergRush Exploit). But on the other hand I really doubt that these changes can be reverted to the state, that SE repair center would not be able to detect them and thus maybe cancel my warranty. Which is a bit sad and I did not expect it.
BTW: What is the procedure now to update my firmware, once SE will release it? SEUS refuses to do it... And for sure I would prefer to keep my data, if possible...
If you have unlocked your bootloader, then you will not be able to use SEUS. Try using PC Companion. Even with the bootloader unlocked, PC Companion will work, as long as you use stock firmware.

Not true that unlocking bootloader automatically stops SEUS from working. I had Alejandrissimo unlock my bootloader remotely via the info in this thread:
http://forum.xda-developers.com/showthread.php?t=1254416
And even with an unlocked bootloader SEUS worked just fine (that is until i flashed to the latest firmware posted on XDA in the Xperia Pro CM thread). But that's only true if you use his exact method. It seems that all other methods do prevent SEUS from working.
But yes, as soon as you've unlocked the bootloader, regardless of the method, your phone's warranty is void. That includes unlocking it the official way via the sony ericsson website! PITA
And technically, if you even root your phone, you've lost your warranty as well.

Yes sure, but my point was not that this act voids warranty, which is clear and obvious. My point was about the fact that many people in forums are understanding rooting and other hardcore activities in the way, that "if something would go wrong with my phone, I still can revert all changes, reflash it to out-of-the-box condition and send it to repair service, while they will not be able to detect the phone used to be rooted or altered in similar way", but in fact there must be some detection mechanism which in certain circumstates (as is my reflashed phone) will recognize that phone has been rooted in the past. And my phone is now not upgradable by both SEUS and PC Companion.
Not exactly. If you root your phone without unlocking the bootloader(zergRush exploit), then you can reflash it using SEUS or PC Companion & any track of the rooting will disappear. But if you unlock the bootloader, that's permanent. Even if you relock the bootloader, you will not be able to lave it as it was before unlocking, as the DRM keys are deleted when unlocking.
If there's still interest, I have a stock SEMC/MK16a:2.3.4/4.0.2.A.0.58/xf_v3w:user/release-keys phone and I'm yet to start fiddling with it.
If there's anything worth extracting from it just let me know and I'd try.

[Q] Rooted Ion (2.3.7) denied by SEUS (SUS)

Hello all,
I have Ion LT28i rooted running 2.3.7, when I try to update it to ICS using SUS, I get an error message "The phone contains modified software that cannot be updated"
Granted, I can fix this by flashing back the stock ROM, and update using SUS the regular way...
BUT, I am trying to avoid the hassle and risk of backing up/restoring everything on the phone, I did the upgrade yesterday on my brother's non-rooted Ion using SUS, and the phone migrated all system settings and apps without missing a beat... I would love to have the same luxury on my phone...
I tried 3rd party apps to backup my current rom (Nandroid and ROM manager) both crashed and burned due to compatibility issues with Ion.
Is there anyway to trick SUS into thinking my ROM is stock, and accept to update it?

Any recommendation on the best backup method to migrate? I have a Titanium backup now, but that obviously needs ICS rooted to restore from it after I am done SUS upgrading...
Back in the X10 days, SE released a backup/restore app that migrated user data from 1.6 to 2.1 after upgrading with SEUS...it was pretty seamless...
Actually, a better question I should ask here, to confirm, flashing back stock build 6.0.F.0.111 will delete user data... correct?

You can use flashtools to flash back to the stock ftf and uncheck wipe data. That should get you back to stock with your data still intact. Just remember any issues that pop up will probably require a wipe. What did you use to root GB? a prerooted system image or kernel? Either way probably means you unlocked your bootloader which will need to be locked also before you can update via official methods.

Yep, happened to me when I rooted, and the phone crashed at first boot, and took it on its own to wipe data, although I told it not to... I was not a happy camper...

I did indeed... I unlocked the BL, and used flashtool to load a rooted ftf
With the unlocked bootloader, means you stop getting updates from Sony completely if I remember correctly and you will have to upgrade by flashing only.
Spectre,
Would SUS be happy enough if I lock back the BL (per your instructions in a different thread), but keep the rooted ftf? SEUS never got bothered by rooting with X10i...
would relocking wipe data? (it wasnt mentioned in your instructions)
Relocking shouldn't wipe data and should be enough for flashtools as long as you are using a stock kernel.
Sent from my Sony Xperia™ ion
Alright, I decided to bite the bullet, and figured if I lose the data, I lose the data...
None the less, came up with a hybrid solution to relock the BL, get ICS, and not lose data... not a single bit!!!
in details, anyone that Unlocked BL and Rooted their 2.3.7 ION, and now getting an error when trying to upgrade with SUS, here is how you can resolve this issue:
1- relock the bootloader as explained by Spectre51:
Spectre51 said:
RELOCKING BOOTLOADER WILL ALLOW YOU TO GET NEWEST UPDATES & REPAIR DEVICE USING SEUS/PCC
Before we begin relocking the bootloader make sure that u have flashtool download & installed
You can get the latest version of FlashTool from:
http://androxyde.github.com/Flashtool/
Download link is under "Installation" tab
If you have not use FlashTool before read this thread:
http://forum.xda-developers.com/showthread.php?t=1526866
Download this FTF:
Xperia ion -> LT28-ION_Relock_bootloader_Dogsly-TEST.ftf // Mirror 1
NOTE: This file has not been tested. If you attempt to relock the bootloader using this file please post your results
Flash this FTF via FlashTool:
When it says enter flashmode, power down device and keeping VOLUME DOWN button pressed connect usb cable to phone, the device will now enter flashmode (green LED)
After this file is flashed reboot phone
Bootloader will now be relocked!!!
Incase device doesn't boot DO NOT PANIC...
Click to expand...
Click to collapse
2-when the phone is "broken" as described above, and stuck in endless flashmode boot loop, DO NOT FLASH STOCK ftf with flash tool, instead, start SUS, and allow it to update as usual.
3- since your BL is now locked, SUS will be happy to download 383MB FW, and install it on your phone, SUS will actually upgrade your phone to ICS, and in the meantime, fix your boot, AND retain all of your data.
4- once SUS is done, diconnect, and start the phone, Android will upgrade and migrate your data
5- enjoy ICS, and all of your data and history... the only thing you lose in the process is root...
6- feel free to root the phone again if you still need it rooted for any reason...

hi bayhas, I have a question regarding what you did.
I have a Xperia S, BL unlocked rooted 2.3.7.
And I have actually the same annoying fear and question:
1. Is it even possible to upgrade via official PCC?
2. if not, and the only way is via flashtool, can I upgrade to 4.0 without losing a single data? with that I mean contacts, sms, some phone settings (not that important), most important are all my games and app DATA which are stored on both internal SD card as well as on internal phone memory (Android/data...etc).
I have this bl unlocked + rooted Xperia S since May 2012 and am really scared to lose anything due to a past experience with Xperia Arc S, by upgrading a rooted which wiped a lot of my data via the official way... afterwards I couldnt even upgrade and had the same error you had.. I really dont know what to do now. Im fine with how my Xperia S is but I have 2 big problems nowadays:
1. when ever I play certain games or very sometimes open browser a certain site, my phone freezes and I can do nothing except a reboot (power button + volume up).
2. now the reboot is annoying, AFTER reboot I happen almost every time to have "application not found" issue, which can be fixed by REBOOTING again or reload SD card or just install that app (overwrite) again. which is also super annoying if you know what I mean.
I dont know if you experience above 2 problems when u were using 2.3.7. but I have now and the FREEZING appears every 1 to 2 days when during gaming (not all games...some)... what do you advise? I really dont want to go to trhough all the panic of losing data or other new problems....

[Q] Arc S android update suggestions (for backup and space issues?) - noob :$

Hi,
I'm having problems with space and the general speed of my Xperia Arc S so the time has come to finally upgrade from Sony's version of Android 2.3 in hope that it will improve things.
I've kind of avoided this so far as I don't really know the best way to back-up things.
I want to back up to my computer - not to the internet.
I am guessing that for the applications that I would like to back up I would need to back up both their APK files and whatever their setting files are. I guess there are also some system settings to back up (but then these are less important).
A problem I have always had is space on the phone - it has very little storage space and although I try and move everything to the SD card, a lot of it doesn't seem to be able to be moved.
Things like simply the Google Play services take up loads of space! I don't even really have that much on there - mainly just whatsapp.
The phone is stock although I have checked in the service menu and it says that I can unlock the bootloader. Part of the reason I didn't upgrade to Sony's version of Android 4 was because I heard that it locks the bootloader and I didn't know if this was bad.
What is the bootloader unlock for? Is it for loading custom roms? As i thought you could do this even if it was locked? Or is it for rooting?
So yer, I guess I am looking for recommendations for a CFW to suit my needs. Priorities are that it works and i'm guessing the latest android version possible would be best as this will help with performance etc. Or is that a misnomer as newer android releases are generally geared for phones with higher specs? I've heard that some CFWs have problems with wifi etc so i'd like to avoid those as I certainly need that.
Overall there seem to be so many even on this forum that I don't really know which would be a best fit for my needs or this phone.
I also have an original San Francisco (zte blade) to update but will save that 'till I've done this one.
Hopefully I can get an understanding as to how all this CFW / Rooting / whatever business works and the best / latest way to do things, as as with everything, it all rapidly changes and you can find yourself looking out lots of outdated and now incorrect or superseeded information.
All a bit overwhelming really, which is why i've put it off so long!
Thanks for your time and help!

I have android 2.3 - is this a problem?
I thought that the Sony ICS 4.0 update made it so you could not unlock your bootloader?
Hmm if you unlock your bootloader, it will also root the phone, correct?
But it seems that using the Sony tool will wipe my phone developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
So i saw there is the S1tool but then people said that it does not work with the Arc S.
Is this still the case? What is the reason? is it impossible?
So, you say that in order to back up my applications and things, i need to unlock my bootloader. The official way seems to wipe my phone though - so then i can't back up :S
Hmm, see, i am confused about the order i should do things. Also i've heard that if you use the Sony tool then you cannot use OTA updates which seems like it could be problematic? Mind you i guess CFW cannot use OTA either - so how do you update? You must check for updates on your PC and reflash your phone regularly? Or are there ways for Stock android CFW to support OTA updates?
So, does the Sony ICS update stop you unlocking the bootloader?
I guess there are 2 options. Update using that and then install helium OR root and then use titanium backup.
Not sure which to try.
Thanks!
1. Unlock bootloader is only affected by the phone manufacture date, check the battery compartment and see if the date is before 12W11. Any date after this means the phone can't be unlocked.
2. Software does not affect the unlocking of bootloader, like I mentioned earlier check the battery compartment.
3. Unlocking your bootloader does not mean you have rooted your phone. It just means you can flash custom kernels onto your phone.
4. It's not that S1tool doesn't work, if I told you the entire process of doing it you wouldn't want to do it either.
5. Sony last stopped the update at 4.0.4, no need to concern yourself with future updates.
6. If you use CFW, refer to the thread for instructions on how to install updates.
7. Like I mentioned, ICS update does not affect bootloader unlock, only the manufacture date does. Furthermore, if you update from stock to a CFW, you will not be able to restore your data from the old software. You will have no choice but to start with a clean slate.
I am on Sonys 2.3, build 4.0.2.A.0.62 and i read that i cannot root this version.
I can't use backup software as i can't root to use titanium and helium doesn't support 2.3.
Sony back also apparently doesn't support my phone.
Basically, my apps are outdated due to me not having enough space to update them.
I think that updating to Sony's ICS update might enable me to use these programs and root so that i can backup, then unlock the bootloader and use cfw. (i checked and my s# is older than 12W11 so that's fine).
However, i am worried that if i try to update to Sony's ICS update that i will either lose my applications or the data that is stored with them (whatsapp history, game saves, app config etc etc) - particularly as they are not up to date.
Is this the case? Is there anything i can do?
Thanks

Take a look at the tool namend one click root (this thread: http://forum.xda-developers.com/showthread.php?t=2219781), your build should be root-able, just read carefully and decide if you wanna try...
I used this tool on stock sony ics 4.0.4 build and it worked nicely, haven't tried it on stock sony gb 2.3 build though.
Good luck! :good:

Take a look at the tool namend one click root (this thread: http://forum.xda-developers.com/showthread.php?t=2219781), your build should be root-able, just read carefully and decide if you wanna try...

Thanks for the tip! It worked!
If you do it twice it relocks your phone. Took some google translate to find out what the chinese was saying hehe.
I'm now on stock 4.0.3 (4.1.A.0.562).
Doesn't seem a great deal better than 2.3, i guess i need to find out what a good lightweight CFW is really. Firefox for android constantly crashes so i tried naked browser and that does too. Wish there was a good selective script blocker for mobile browsers - that would help a lot. Noscript for firefox would be a possibility but the problem is it crashes a lot even with javascript disabled.
So yer not sure where the problems are coming from, maybe due to the low RAM in this phone. That's why i was thinking a lightweight CFW might help matters but not sure if it's best to go with a 5.1 one that breaks 720p recording and has issues with things like turning off GPS.
Or it might be better to go with the latest type that doesn't break anything. I'm guessing that is a 4.0.4 CFW? Or maybe 4.4? I know stock only goes up to 4.0.4 but i think i read something about being able to get CFW based on stock so HDMI, FM radio, 720p recording etc etc won't be broken?
Thanks anyway!

Well, I haven't tried 5.1 so far, only following the 5.1-threads to see how it's going on.
HDMI is only working up to 4.0.4 roms, FM radio is working in 4.1 roms too, and you'll get 720p recording also in 4.4.4 roms. If you want all things working your phone is able to you will have to use roms based on stock GB or ICS. Therefore I'm using a stock based ICS rom most of the time (T-Rom).
By T-Rom for Arc S, i assume that you mean this? http://forum.xda-developers.com/showthread.php?t=1746508
Or if not then this port of it? http://forum.xda-developers.com/showthread.php?t=2239187
Sounds like something worth trying to see if it helps!
Thanks!

For Arc S the first link is the matching one. I think it's the most recently updated ICS rom for our device :good:

Flash kernel problem

Hi,
today I try to flash KTG kernel on my girlfriend Arc S with ICS stock Sony rom.
I have rooted it with tool (Eroot_V1.3.4) and says rooted.
Even Flashtool says "Root access allowed" but when I try to flash KTG kernel from Flashtool on Fastboot mode, obtain an error (See attachment).
This Arc S is with Unlocked Bootloader, and works perfectly.
I want to flash KTG to install a custom ICS ROM (Zohaib one).
With my old Arc S I do it without problem...this problem never happened to me. Now I don't know how flash kernel.
I try to re-root device with Flashtool option (My LT18i-->Root) but even that options, after launched., says ROOTED, busybox installed and I see SuperUser on apps in the device.
Someone can help me? Read Flashtool video logs....what's happened?
How can I flash KTG with this problem? It's related with ?
you probably fixed that by now, and I am no expert, but I just solved a lot of my problems by using a real old flashtool v 6. something.
It had no problems acknowledging bootlader status- unlocked which I had convinced myself was relocked. It rooted no probs first try with the padlock and fastboot installed .img which I just couldnt get to happen with other versions.
I also could not uninstall system apps no matter which rom/kernel i tried, I had SU in the apps but it was if wasnt really rooted.
I am finding a lot of dead links, figures because this phone so old now, and the forums are just too big to navigate. I am now trying Rush with UHD 5.0 since today, but it is chewing through the battery, any advice?
Any old files you could send me?

I have fixed the problem selling that Arc S.. Now I'm on my Z1C only.
But thanks very much for your answer and attention...these problems are known about root.
For root ICS Arc S, use EasyRootToolKit from this forum...for me works (disable antivirus first)
As ROM, I use for years Xperia T ROM from Zohaib, that goes well and mantain stock features of Arc S.
Or, if you want to try something different, you can try "Superjellybean ROM" that goes well on my Arc S...flash SuperFusion Kernel and try the lightness of Jelly Bean 4.1.2
Have a nice day!
