[Q] Can't flash from .64 to .70 via flashtool. Why? - Xperia Arc Q&A, Help & Troubleshooting

Good day to all,
i've installed a new ROM (IceLite ICS) on my Xperia Arc.
The ROM is pre-rooted, and via flashtool it seems I have root permission.
The phone has the bootloader unlocked, CWM 5 and the baseband is the stock .64.
But apps which need root (like SetCPU) don't work, and SuperUser never ask for permission. I thought about a baseband compatibility problem with the new ROM, so I've tried to flash .70 baseband, but Flashtool always stuck at "Unplug phone, set off, push and hold menu, plug usb" window.
Any idea of what's wrong with this?
Thanks

Don't know about that Rom but baseband is not connected to superuser.
Also bb64 works fine with ICS.
Use flashtool 0.7.x not earlier for flashing anything ICS related.
Good luck.

Sounds good, how do I install it in simple terms? Sorry if I sound like a orange :-S
Is it just a straight install or do I need to mess with kernels etc,
How's yours set up? Rom/Kernel etc
Help is much appreciated

Since it already has doomlord's kernel on it, it is rooted and the bootloader is unlocked, so you can probably use fastboot to install most roms. If you want compatibility for all the games, stick with GB. If you go to an ICS build, you'll likely have problems with certain games crashing, graphical errors, or gamepad not working.
I have no problems with the gamepad so far using DarkForest ICS.
I tried ICS++, I prefer Darkforest still. Probably sticking with it till the real ICS.
There are so graphical issues, but its pretty nice, no bloatware either.
If you already have a kernel with recovery, all you need to do is install the .zip file for the ROM through it.
Put the zip on your sd card, reboot the phone. While it boots and the light turns blue, press the back button.
I attempted to update the kernel earlier and bricked my phone, I the fastboot method and actually completed the flash, when I powered on the mobile it was just displaying a black screen,
After looking about I got the stock rom and flashed it, and its working again!
Now my mobile is on stock rom with stock kernel,
It displays a message saying theres a system update available but when I connect to pc I get some message saying the software cannot be installed because the device has unauthorized software on it, I also got this message before I flashed to the stock firmware so it seems that they know my mobile was rooted etc and cant update through their software...
Could someone kindly walk me through what I need to do to put doomkernel v13 and jokawild rom on,
Thanks

Any suggestions,

Flash stock ROM with flashtool, load fastboot, flash kernel image for DooMKernel, boot into recovery, clear cache, apply the update.zip for jokawild, done.
If you need more detailed instructions I'll write out a full guide later when I can use my home PC.
Actually, I was thinking of doing a full guide with pictures anyway.

[Q] Boot loop! Can't get into recovery. What to do??

Hi,
I got my phone stuck on bootloop, and can't find a good idiot-proof guide on how to fix this without the ability to get into recovery.
Here's what happened:
Last night I figured I'd give it another shot trying to get a custom rom on my Arc. This didn't work because I couldn't get into recovery anymore (??)
So just now I figured I'd re-install CWM, so I ran the program, it didn't work.
So I ran it again; Didn't work.
Well, I ran it again, and the program said it worked; So i try to boot into recovery, and it's boootlooping ((
I don't know what happened here (it has to have something to do with the cwm installation program), and I don't really care at this point. I just hope there is someone here that's willing to write up how to get it working again.(in an idiot-proof guide )
Thanks in advance guys
I would just re install stock either by using pcc or seus, or flashtools which is the preferred method for most.
If using flashtools you can choose which stock rom to use look in the stickies for the need roms etc.

[Q] WIFI issue on xperia arc ICS 4.0.4

Dear All,
does anyone know why WIFI on xperia arc ICS 4.0.4 always disconect and connect?
any solution???
thanks looking for your help....
maybe you flashed lt15i firmware on lt15a
I've flashed the Generic Global World 4.0.4 but I don't seem to have any problems with wifi.
I flashed a global ics on my arc and i ve got the same problem you re not alone mate...
Sent from my LT15i using XDA
Is it a kernel prob what kernel are you using ? Also do you use battery defender because I know that messed up my WIFI on 4.0.4. You could also use something like WIFI lock from the play store. Hope you get it sorted.
Try repairing using pcc or sus and before installing format the sd card and reset factory settinf and install the software twice..
Hope that helps.
download wifi fix from playstore and run it . That will definately solve your problem . Do click thanks if i helped you ...!!!
Sorry now I downgrade to GB 2.3.4
It better for me ;-)
Everything is working fine...
What I did I follow structure to flash rom that can root and flash kernel back. This is what I did when I use 4.0.4
If I don't do this I can' t root my phone...

[Q] Problem with Xperia Pro(MK16i)

I am sorry if this is in the wrong place, but i could not find a pro specific forum.
Anyway i have a potentially huge problem. I tried to install CyonagenMod 9 on my phone but now it just shows a black screen.
I had previously applied the official SE ICS update(build 4.1.b.0.431, i think), but it was really draining my battery and decided to try CyonagenMod.
Everything was going smoothly i unlocked the bootloader, then i flashed the boot.img and restarted the phone but nothing happened.
Is it because these instructions were meant for 2.3.x? Or something else?
And is my phone permanently damaged because of this?
Thanks for the help.

1.Does the flashing of the kernel went smoothly? Does it says "0 bad blocks encountered?" if not, maybe ur pc does not have some of the drivers needed to flash the kernel. This can be resolved by downloading and installing the appropriate drivers.
2.try flashing ur phone with stock sony .ftf firmware using flashtool.(doesnt matter its 2.3 or 4.0) and then try again installing cm9 rom if u wnt to

Yes kernel flashing wents smoothly 0 bad blocks.
I tried what you suggested and got my phone to work again. Then tried to install CM9 again, but got the same result as before.
There's a separate pro version for CM9. Are you flashing the arc version instead?

No i am sure it is the right one. The developmenname for pro is iyokan and it says that on the zip file i am using.
cm-9.0.0-RC1-iyokan
Oh, did you flash the Officiall CM9? The Kernel is Broken, use FXP CM9 Kernel.

[Q] is baseband important when you are moving towards New Custom rom?

any one plz tell me last night i flashed baseband 56 for Blend miui should i change baseband for another Custom Rom?
Using Xperia Arc S
For Gb Roms - Baseband 64 is recommended
For ICS/JB Roms - Baseband 77 is recommended.
Sent from my LT15i using xda app-developers app
No! Baseband is basicly to do with making phone calls mms etc (short explanation) you do not have to change it for every rom unless the Dev recommends a particular baseband or you have communication problems.I have probably changed mine twice in the last year.:good:
Am stuck
i dont Know Y. i was using Baseband 64 earlier tonight. then this dude recomende 56 kernel for his rom. i did.
now am flashing 64,72,77,83 every time its Giving me an error
That's why I have only changedmine twice in a year I would return to stock and start from the beginning :fingers-crossed:
this means av to move back to stock by repairing my phone by PC companion and then Root it again and install custom Rom?

Do not use PC companion if your bootloader is unlocked this can brick your phone
Oh God i was about to.use it last night then i forgot.
PlZ suggestme something my bl is unlocked

I'm not a expert on basebands I try to stick to same one unless I have major problems.I understand you need to flash the libs zip file with cwm included with basebands and also obviously flash your ftf baseband file.Also use the latest version of flashtool follow this link for basebands you probably been there already but it as the basebands plus lib files Link: http://forum.xda-developers.com/showthread.php?t=1688049 :fingers-crossed:If not do more research maybe return to stock Also read this Link: http://forum.xda-developers.com/showthread.php?t=1382657 Also update a guy in another thread had same problem and used old version of flashtoool Quote " Problem solved with flashtool 0.6.8.0" you could try that version as well.
