[Q] So, how to keep the root from .58 to .62? [Solved] - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

EDIT [Solution]:
TL;DR Use wotanserver to flash a US Generic .58 firmware, then root the phone using flashtool ZergRush exploit, check for updates and OTA update should be available.
Ok, seems like some people can't update by OTA to .62 after rooting, because it keeps asking for PC Companion.
After several tries, I realized the problem is the firmware.
I used Wotanserver.. tried Latin American, and countries from south America .42 and .58 firmwares, none worked...
But the last try:
- I picked the "Generic US .58" from Wotanserver, and flashed the phone.
- Without installing nothing, rooted it with "Force ZergRush" using Flashtool 0.6.7.0
- Then enabled the internet, and checked software updates, there it was the .62 and for my surprise it would finally allow the OTA update, did it, and 5 minutes later I had a .62 rooted SK17a Mini Pro.
So just try the US firmwares. Guess they´ll do the trick.
OLD POST:
Sorry if this have been answered already, but I can't seem to find anything..
I just heard some people saying if you use PC Companion to update from a flashed .42 or .58 to .62, the root will be gone. And you need to update "Over the Air" in order too keep the root.
The problem is that when I try to do so, the phone says (SK17a): "PC Companion Needed, yada yada you need a computer in order to update your phone" ....
So I'm stuck or ... ??

Some people succeeded and many peoples are not.
I want to ask to succeeded people.
How or where did you get the 5.8 or 4.2 firmware and what kind of or which versions firmware.
This is s very important things.

go to wotan server website.
locate your phone & inside that page you will find tutorial to flash the firmware
follow it & install .58 or .42 version
root it using zergrush method (you can check the guide link in my sig)
make sure you don't change anything in the system, just root it only (you can install other apps like titanium backup, root uninstaller etc)
after that do the OTA update.
phone gets restarted & you still keep the root.

Ok here is the deal, these are the steps I followed, notice the difference from your instructions:
Went to wotan server
Installed a Generic Latin American .42 firmware
Used Flashtool to root the phone (it stated that used zergrush exploit)
I installed NOTHING but the market which automatically got updated.
In the notifications appeared the ".62 update available"
Tried, but then asked me for a computer to commit the update.
So my guess is:
- Either, some firmwares are not allowed to being updated by OTA or ... maybe in some countries is just impossible.

id say ill stick to .42 or .58 for now and wait until official ics updates comes from sony ericsson.
infact its not that a big deal of needing to root .62. its not like .42 and .58 fw has problems

US Generic 5.8 firmware is a GSM?

---

mini pro it self is a gsm phone

---

This way's working for me.
I hope keep the root after update to ICS.
Thanks.

Just a suggestion to all, do not update the superuser app. Latest version 3.0.7 gets hanged in .62, nt sure if its an issue with the app or compatibility wid .62 fw.
3.0.5 version works fine
Sent from my SK17i using XDA App

I have a sk17a model with pt-br keyboard (with "Ç" key).
I read that I can flash a sk17i rom but will the keyboard work properly?
Can I follow this method?
Sadly I don't have a .58 sk17a rom from my country to give a try since I update from 2.3.3 to 2.3.4-.62 with no other steps.

You can give it a try (p.s. dnt blame me if anything goes wrong )
about the keyboard settings, well if u are successful to keep the root then you can change the keyboard settings. you have to follow this guide.

Thanks, man. It works.
I downgraded with wotan server to sk17a .58 US (and lost my Ç).
Then I rooted with doomlord v4.
Updated to .62 over wifi.
And finally used the doomlord's Hardware Keyboard FIX you mentioned.
Now its rooted like a charm, with Ç and everything.
Took me half hour or less since I knew what to do.
Very thank you for the attention, guys, again!
