Can any one please tell me how to downgrade Xperia X10 Android version from v2.1 to v1.6?
I have Xperia x10 Rogers (Canada) phone. My phone was locked once (the pattern problem) and to resolve the issue, I upgraded the android version to 2.1. It seemed to work.
But now my phone is working really slow. I'm also having service problems. Now I think it was much better with v1.6. Can anyone please tell me how to downgrade to the v1.6 (Eclair). Or if is there any other way of resolving this issue.
in desperate need of help

Here is the original 1.6 for Rogers Canada

...and here is the thread for the guide to step by step of flashing 1.6
Why don't you try "repair software" via SEUS or PC Companion before going back to 1.6? There are many Rogers members running 2.1 on xda, and I have never heard of this problem.
Also, to fix the lag problem, try rooting, optimizing (enable JIT), and removing SE bloatware like face recognition and timescape. All can be done with one click each with Flash Tool 0.2.9 found here....
http://forum.xda-developers.com/showthread.php?t=920746
So what is the latest with bootloader?
Lets discus everything here, where everyone can speak
and moreover that thread should be kept clean because a lot of work has still to be done.

Greetings.
warning.
if you are not developer, please quit reading that post.
wait for user friendly tool with one big button.
here ( View attachment 712577 ) is toolset to permanently "unlock" semcboot of msm7227 semc phones.
that means, you can use own kernel and so on.
steps,precautions, etc.
unpack archive to any directory.
if you using eset antivirus or similar ****, it will find evil virus in adb.exe.
ignore that, it is not virus in any way, it is standard android debug bridge, bundled in one file to save space and usability.
now, if your phone unlocked officially:
flash phone with standard 2.0,2.1 android firmware,because kernel mapper module compiled for "2.6.29" kernel.
of course, enable "usb debugging"
run msm7227_semc.cmd,
( if you want, examine it before run, it is pretty straightforward. )
you will get similar output
Code:
process requires standard 2.x android firmware.
Press any key to continue . . .

Writing patched semcboot. Two step process
First, we need get access to semcboot area
504 KB/s (8064 bytes in 0.015s)
Second, we need to write semcboot ;)
1130 KB/s (596916 bytes in 0.515s)
successfully wrote 0003ff00
Press any key to continue . . .
bingo, your phone now has unlocked bootloader.
if your phone unlocked by setool2 software, use msm7227_setool2.cmd
if your phone unlocked by 3rd-party software other than setool2, do not run anything -
it will disable radio capability of your phone and you will need to unlock phone by setool2 software.
hopefully, mizerable flea and mOxImKo will release something similar for your phone.
okay, now about other details.
1.
unlocked bootloader require unlocked loader, yep ?
loader\loader.sin is special unlocked loader, which will be accepted ONLY after your "unlock" semcboot with previous steps.
to distinguish unlocked semcboot and original semcboot, first letter in version tag of semcboot output will be lower case, i. e. "r8A029"
( same applies for loader version tag )
so, all that stuff with signatures are not for us, so i removed them - loader will ignore signature part of SIN file.
2.
we should make SIN file somehow, right ?
for that i prepared "dumb" bin2sin utility.
[input] - is input binary file.
[partition info]
android implementation on s1 semc qualcomm phones based on partitions,so we MUST define it for our file.
you can get required partition info from standard semc sin files, it is first 0x10 bytes of DATA, right after header, i.e.
[type] - partition type, 9 - partition without spare, 0xA - partition with spare.
kernel partition is partition without spare.
if that parameter omitted, type = 9
[block size] - nand block size, if omitted, it is standard size 0x20000
there is example in sinTools\example_build.cmd
3.
kernel should be prepared specially to be accepted by semcboot.
for that there is tool bin2elf.
we need 2 segments:
segment 1 is unpacked linux kernel image, i.e.
( e10/kernel/arch/arm/boot/Image )
it looks like entrypoint and load address for segment 1 is always same for all msm7227-based semc phone, it is 0x00208000
attributes for image 0x0
segment 2 is ramdisk.
it looks like entrypoint and load address for segment 1 is always same for all msm7227-based semc phone, it is 0x01000000
set attributes for ramdisk 0x80000000, that is extremly important.
there is simple kernel example in sinTools\example_build.cmd
ps.
@blagus:
NAND MPU disabler has only one relation to rFoNe - he took it from setool2, together with entire idea for msm7227 bypass.
your 6-wings friend with many nicks done exactly same.
NAND MPU has nothing to do with memory firewall, so it will not help with kexec things, however, who will care now.

I like to take this opportunity to thank all the devs involved in this process, especially blagus as he was the driving force behind this, without him I doubt
the bl would have been cracked and also I am really thankful to an new X8 hero the_laser for achieving something that will change our devices and enable devs to develop our phones much further than ever.
OP, please include original post in BL thread from the_laser in 1st post, this will keep non dev's out of BL thread in dev section and hopefully keep it clean, Thank you.
I dont think true multitouch is supported by synaptics hardware so we prob never have real multitouch.
I think Blagus confirmed that sim lock is seperate to kernel so prob wont be able to unlock device from network.
Above comments need conformation from a dev.
So, the bootloader unlock is done. Now users like me Can know that "We must wait for a super one button press program." em'I right?
if we unlock our bootloader from original se firmware, will we still be able to flash a custom rom, i.e. froyobread and still have it unlocked?
Congrat to all dev... Finally our X8 can be free up from SE kernel.
So... To unlock we need to flash original 2.1 firmware... Then we can still able to install current custom ROM or we must wait for new custom ROM after unlock?

Can anyone sumup what doors does this open in terms of development? Increase in performance, additional features?
Nothing more than the hardware allows... next... kernel...

You can install them already...what d' ya need BL unlock? I can't believe the stuff I 'm reading... ppl wondering if they'll be able to use current roms after unlock...
Except for the devs who will take advantage of this for making better roms u need not bother about it. No one forces u to do anything right now... use the phone and wait...

I'm talking about compatibility not asking some noob question, as far as I can see no one else was yet to ask and I was curious, so why can't I?
I wanted to know that if i unlocked my bootloader in preparation for custom kernels would I still be able to install the custom ROMs that i have come to so enjoy and appreciate, you don't exactly have the answer so don't come in and try to indirectly flame me.
i THINK i remember reading somewhere that if we unlocked the bootloader we could remove the fps cap. or maybe im just dreaming?
no more fps, meaning that games will be ultrafast?
just dont get too excited guys there are no official announcement especially from the developers. did anyone here tried to unlock there bootloader using that method and confirm if its really does unlocked/bypass the bootloader? For now answer "NONE", so i guess lets wait and be patient, disappointments are always around. My observation and opinion tells me that if its already confirmed Blagus will actually reconstruct the first page of Bootloader Dev thread for confirmation, that what i thought.

I unlocked the bootloader on my x8 while running GingerDX and MPU disabler tool. I think that you should wait for further information before unlocking your bootloader.
@Questioner
Is this unlock of bootloader a bootloader bypass or bootloader crack?
@Mika Dee
Blagus has reconstructed the first few posts already.
Unlock a BL isn't useful if there's no new kernel, and it will takes a lot of time to write a kernel.
yeah, whait for tsunami tunning x8

There are already 2 other threads about the same subject... Unlike u, I already saw ppl asking the same thing which u say u haven't... Do whatever u want m8. Whether u try the unlock or not this soon won't hurt me. You can put a tail on it and call it a weasel. I was trying to explain that the whole point of this breakthrough is the use of better kernel for starters... It's like you 're too eager to unlock the bl without anything to benefit from it afterwards. I can't do what the devs will, the ones this unlock is mainly targeted to, for now.

Well then I do apologise for picking the thread which seemed to be the most active, rather than going anywhere else to ask being as I thought this thread would be the place for me to get the quickest VALID answer (@SpyderX - Cheers for that mate, I unlocked mine successfully on FroyoBread V023b UD11b) And being as you don't seem to know what I do, which is testing for developers here and there on different sides of the Forum with my mates HTC Widlfire S, so why should I not? I'm not jumping to the conclusion that I will actually end up testing for any one of the many brilliant developers here, but why not plan ahead? As far as I am concerned you have yet to give the answer i was looking for, someone else has managed to help me out, so save yourself the effort of replying, I'm sure your useless comments are needed elsewhere.
Beans.
Little update: X10 mini pro are about to have their first kernel. Looks like devs have the capability to build a kernel very fast ;D. X10 mini already have custom kernel. X10 has their first bootloader unlock kernel rather than bypass kernel.

Glad some1 else helped where I thought the answer was obvious. Enjoy your phone... and u will be a tester after all for the devs. We all will be in the near future... The new kernel is still the answer to the usefulness of the unlock...

Hello XDA Forum, I would like to say sorry if someone has allready asked this question, i have checked the forum and couldnt find the infomation i need to help rooting my R800i.
the phone will not root for some reason. i been on this website offical unlockbootloader.sonyericsson website to get my ID.
when i try to Root the phone i get to step 10 (off the sony ericsson website) and the phone doesnt do anything. the blue light doesnt come on, it stays green. s1boot download pops up in my Device Manager but when i point the driver to Folder it says to on the site it says it cant find anything.
i am running 2.3.3 and updated to the latiest version, i heard i might need to downgrade the firmware or something, i am a complete noob and would really appreciate any help from members who are more aware.

You can flash the generic UK 2.3.2 firmware without an unlocked bootloader, then do an OTA update to keep root. There are several threads on here about it.
Look for the thread about flashtool, the UK generic and gingerbreak.

thanks for info, i have managed to get in contact with Alejandrissimo i have now ROOTED my phone

Please don't take this the wrong way...its just a question...nothing implied.
Whats the need or attraction to unlock the VP? What is gained?
Again, please don't read into the question...its just a question.
You can downgrade to retail wp7 7004 t-mobile by using tutorial from next thread: unbricking dvp. Just flash retail ffu, by mensioned methode and here you are.
be carefull: any errors during flashing may cause a brick.

Ya i am wondering the same thing as Chevron7 never supported the DVP, there seems to be no reason to do this? unless maybe you want to try and interop-unlock the phone but again that has never been done... yet
Some of us are developes/tinkerers that love to mess with whatever we own.
Dev/interop unlocking is part of this, you could simply unlock to fiddle around with the contents of the rom and just that much.
If WP7 had something as well made as root explorer, that in it of itself is reason enough to unlock. You can learn a lot about an os just by figuring out how it ticks. (Just one of many reasons to unlock, your mileage may vary)
Hey guyz ... Howz all doing. okie here's the deal. I am new to this whole Windows Phone 7 stuff used to play a lot with the HTC Elfin i had with WM6.1.
Tried a lot of stuff on Transformer too.
Now itz time for Samsung Focus , as my first Windows Phone Device.
I have read countless articles on this forum but still have a few doubts remaining.
1) Can the 8107 Mango bootloader be replaced with MAGLDR or it will screw up the device ?
2) Is it ok to flash MAGLDR & Custom ROM with an external MicroSD card inside ?
3) I cant find anything to backup stock rom and bootloader & restore it back in case if the device is burned. I found 1 or 2 but some report that restore isnt working. Can ny1 help me out with this.
Lastly the phone is on its way to my place so I dont know if it is a 1.3 or 1.4
But i need to get the above questions cleared as I have my xams running and can only giv 1hour fr the unlocking stuff. So just want to clear all the doubts before the phone arrives.
Thanks a lot guyz !!!
*BUMP* Please Help me ASAP Guyz....
That's because when you flash MAGLDR/custom roms, you do it on your own and accept the risks.
And yes, you might not be able to restore. In theory, you should be able to restore after flashing back a stock ROM, but I for one haven't tested/verified that.
Remember, all these are on your own risk

2. Yes

No it won't.SIM unlocks are not written on the rom or firmware.So it can't be erased by flashing.

I have to redirect that to my sig:
"Before asking questions, please read the Samsung Focus wiki and search the forums!"
Quote from the wiki:
Formatting, Flashing, upgrading, downgrading OS and firwmare doesn't affect Network lock (SIM lock).
Locks are in NVRAM - you do not overwrite this section by flashing firmware or formatting.
If the device is already SIM unlocked, flashing/updating/downgrading/formatting/etc the ROM will keep the phone unlocked.
Thanx a lot for all the help will flash tango tnite
Hoping not to brick my newly acquired device
Installed MAGLDR
Installed CleanROM !!
Profit!!
