About the baseband flashing, just untick "wipe data" in flashtool when you start to flash the BB.

i have a question regarding this too. I've been using custom ROMS with bb .54 but would like the option of switching back to my stock 2.1 ROM, which had BB .49. it seems like the stock rom doesn't like the current bb and when i restore it via xrec it doesn't recognize get any radio signals. what should i do? I tried downgrading to bb 0.49 but the same problem persists

[Q] Restore data?

Hey people,
I updated my X10i yesterday to zdzihu's freeX10 beta 4, using baseband 2.1.54.
I backupped my data with xrecovery and with sony Ericsson's backup and restore, but I'm unable to retrieve the data.
Backup and restore isn't stock on the rom, and I can't install a .apk file, when I do so my phone says "application not installed".
I tried advanced restore in xrecovery to restore only data, but then my phone gets stuck on the boot screen with the sony ericsson logo, so I have to pull out my battery, restart xrecovery and restore a backup which I performed just after the update.
I would really like to get my data back, is there any way to do this? And how can I prevent such data loss in the future?

I would suggest a fresh install of free x10 beta4... DO NOT RESTORE ANY THING.. the problem is that you are updating from anDroiD 2.1 to 2.2.. a whole version... apps cannot be restored if you jump from one version to another...
HIT THANKS BUTTON IF HELPED IN
ANYWAY..!

Both won't work. You should've backed up your data with mybackuppro or similar apps.... I ran into the same problem (since I used the stock backup & restore app).
I think the only way to retrieve the data (contacts, sms etc.) is to flash back to the stock rom, and back up your data with other apps before flash to custom rom again. As for the apps, I hope you kept a copy in your computer somewhere if it's not on the SD...

Ah yes I haven't thought about that!
Where can I get an official 2.1 rom? I was looking on the forum but I don't know which version I have to choose, as I live in Holland but there are only German and United Kingdom versions to download?

It shouldn't matter... as long as it's the 2.1 rom it should have the original backup & restore app installed. So you could restore your data with it and backup with something else.
This thread has all the firmware: http://forum.xda-developers.com/showpost.php?p=10879519&postcount=2
I think you should go with X10i 2.1_2.0.2.A.0.24_GENERIC with DualTouch.
Press thanks if this helped

[Q] No signal when using TripNMiUi

When I installed 1.0.63, there was no radio signal. This includes all wireless connections. I flashed my X10 to bb .49. How do i correct it?
Dev tools > bad behavior > crash the system server

I've tried that more than 5 times already. It still doesn't work. However, when I checked, the bb version said unknown. Is there something wrong? I flashed using FlashTool.

Did you factory reset,cache wipe,daviccache wipe,batterystatuswipe before flash rom?
Attempt flashing the the basebrand via flashtool again, then flash the ROM again. Once you do all that "crash system server" again.
Or you can try bb52 like me. It works without any probs.

Install fresh 2.1 via SEUS.
Flash bb 49
install MIUI
crash system server.
you're done

going from 2.1 to factory 1.6(starting over)

i just recently got 2.1b firmware and im trying to start completely over and go back to 1.6. Then I plan to get the next modded rom to use. the troubble is because this new fw has a completely new baseband I cant do nothing with it. Ive tried to use Seus(older vserion) but it says i have the recent software. I tried to flash a different baseband on flash tool but that crashed and am fear of doing it again because I dont want my phone to turn into a paper weight. I googled my search and all I came up with was the firmware for 1.6 but not a detailed explanation on to to revert back.
Try flashtool latest. Try reinstalling seus n PC companion after uninstalling it properly

flash tool I tried with the baseband and service didnt work. The SEUS I had the most recnt version but it says i have the latest firmware and wont let me mess with the software
Restart your PC and try seus you should get repair option however it should be 2.1 but not 1.6(unless you're using us at&t)
Sent from my X10i using XDA App
I tried pc companion and did repair and got a message saying I had the latest firmware. I tried seus and couldnt even get the firmware becase i have the latest firmware apparently
Just simply reflash the baseband even if it crash once or twice :/

after i flash the baseband how do i go back to 1.6 because theres no longer a option to root my phone on flashtool just to flash

Why are you trying to go to 1.6 if you're gonna use a custom ROM? The ROMs all require you to start from 2.1 and there is no way to turn your phone into a "paperweight", great part about modding X10s, its almost impossible to brick.

If I (or anyone for that matter!) help you, dont be afraid to press THANKS!
i figured if i start over from scratch i can have a "clean" phone with no memory of any roms or baseband changes on my phone and I can switch roms with ease. As of right now i have firware 2.1b and baseband .52 but on the phone it shows "unkown base band" from my current posiion i cant use flashtool besides flash so im kinda stuck i cant go forward or backward so im kinda in limbo
If you are getting baseband unknown just go to dev tools>bad behaviour>crash system server. If that doesn't work you have an incompatible baseband.
I have 2.1b firmware and Im trying to root and switch to a custom rom... im currently stuck
Use flash tool to root
Install recovery then rom

[Q] Trouble with Bitsnacker 2.1 on xperia x10

Okay last week i use the superoneclick method to root my device, and have since been reading up on installing roms etc etc.
so i followed a tutorial that got me to instal busybox then xrecovery, i backed up the system before installing Bitsnacker 2.1, when it installed it started just fine, however when i opened my browser it would not close, so i rebooted the phone, it started just fine but my home screen was inexistant, it was completely black. so i figured another reboot was in order, this time i used xrecovery to reboot the phone, this just caused the phone to boot infinitely.
so i reinstaled Bitsnacker 2.1from scratch, its now working fine again, however my phone will not transmit any data, it cant connect using 3g or anything so im having to use my wifi, which is fine apart from when im out and about.
so is there nything i can do to fix this or is this a known bug in the rom? ( i couldnt find anything in the thread for Bitsnacker 2.1)
Did you wipe everything in xrecovery before you flashed the bitsnacker ROM?
Do you have the .54 baseband?
Sent from my Atrix 4G with XDA Premium App
no i didnt wipe everything, yeah i do have the .54 baseband.
the second install is still working well and is very stable anyway

If it happens again, wipe everything with xrecovery then reflash the ROM.

[Q] Baseband Unknown

Okay here is the problemo
i was running D4v10 with siyah Kernel
I had the dreaded unknown baseband, Unknown Imei last night after my phone randomly rebooted. Thought Okay, ill restore it with helcats EFS tool. didnt fix it.
So next i tried to restore the EFS backup with http://forum.xda-developers.com/showthread.php?t=1308546. That didnt work either.
The phone has been factory reset
So i flashed KI4 generic from Intractech's stock thread and used CF root to go with it and it worked my Baseband and IMEI are restored, However now whenever i flash any new firmware VIA Recovery (GB roms, CM9 and AOKP etc) my Baseband and IMEI become unknown. so basically my phone still works if i use a stock firmware with CF root, but i cannot flash any new Roms via Recovery. Not even LP7 Generic works...
Has anyone come across any similar problems to this?
Also Flashing the Ki4 stock firmware, Nandroid back it and then updating to CM9 doesnt work, however when i restore the backup it works again :S

yeah the EFS backup i have is fine. /EFS is also fine. The only way i can get it to work is if i use the KI4 stock firmware. Kernel choice doesnt even matter.

Nothing but stock ki4 results in unknown baseband. That is the problem. No matter what I flash or how I flash it, results are the same.
I only managed to get it to work once with efs pro on a different firmware (lp7). The phone didn't reboot and and after a couple of minutes it was fine until reboot.

There's a known 'Unknown baseband' bug when you charge the phone and flash new roms. Take out the battery for 180 seconds. Put it back in. Go into recovery wipe cache, format cache, wipe dalvik cache. Reboot. See if it works.
Will try when I get home and I'll post the results.

So did it work? Having the same problem here.
Reboot with no charger connected, issue solved?
If not, flash another modem (doesn't matter which one) and reboot (unconnected)
+1, known issue.
