[Q] After downgrade to an older firmware, how to upgrade? - Android Q&A, Help & Troubleshooting

Hi all!
I'm just new to xda and android and liked to do a nandroid backup.
So I read about it and find out, that there isn't any way to do so, without install/flashing/? a Custom Recovery, such like ClockworkMod Recovery, is it?.
So I get ROM Manager from GPlay Store, but it didn't find my phone. Then I downloaded RecoverX from here (http://forum.xda-developers.com/showthread.php?t=1773227) and run it. But this needs root. I think, there isn't any way to use ClockworkMod Recovery without having root, is it?
I try to get root, reading here in that great forum, but it seems, there isn't any way to root my SE Xperia Pro, because it has a Build-Number 4.0.2.A.0.69, and you can only root *.42. There it says, you can flash that firmware, using flashtool (http://flashtool.net). I found a *.42 firmware here: http://dexxmor.de.to/.
So here my main question: After I flashed that firmware and root my phone, how to upgrade to the x.69 one? They all say, that this will be done by "OTA". But my Phone has GB and could have ICS (I didn't upgrade). So when I do so, after that, I would have ICS, right?
Sorry for that n00b question and my bad english
Thanks
PS: Sorry, if i posted in a wrong forum. I didn't found a Pro/Sony General one.

My Device:
Sony Ericsson Xperia Pro (MK16i)
Android: 2.3.4
Baseband: 8x55A-AAABQOAZM-203028D-66
Build: 4.0.2.A.0.69
Kernel: 2.6.32.9-perf

What you are looking for by asking for an update is just making your phone ram hungrier. It would make no use upgrading. Also, after upgrading, by default the root and its advantages will be lost. So it is better to simply keep downgraded, rooted and to mod your phone rather than upgrade it.
Happy to help

Thank you for your fast reply.
You make me unsure, because I always read to upgrade after rooting, but this doesn't make sence of course, if root will be lost.
A last question: What happens, if I won't mod my phone? What happens if I stay with that older firmware?
Kind regards

[Q] Questions about rooting from a very new Android user

First off, I'm completely new to this and wish to root my new sgs2, and I've done some reading on the forum about this but got some questions (or want to confirm what I think I know) before I actually go ahead with the process. I apologize if it's something others have already asked, but I would really hate for anything to happen to what has become my new baby...
I mainly just want root access on my phone as I've come across several apps and what not that required root access.
My phone's status right now:
Android version: 2.3.3
Baseband: I9100XXKG1
Kernel Version: 2.6.35.7-I9100ZSKG2-CL361136 [email protected] #6
Build: GINGERBREAD.ZSKG2
I found (http://forum.xda-developers.com/showthread.php?t=1103399) about CF-Root. It seems like a lot of people recommend this method to root, so I thought I may try it out. Before I do though, I wanted to know:
- Just rooting my phone will not prevent me from receiving any new updates to my phone via Kies, right? (E.g. a new firmware or version comes out in the future...)
- What do I need to do if I wish to unroot in the future?
- For this method, this should be the one I should download and use right? (it's the closest one I found matching my current kernel): CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip
Again, sorry for asking what may be pretty simple questions, but I really appreciate everyone's help!
Hi,
You can follow this (http://knowmydroid.com/guide/root-samsung-galaxy-s-2) step by step guide to root your SGS2.
1) Yes, rooting your phone means you cannot use KIES anymore. Its highly not recommended
2) Download any official firmware from SamFirmware.com and flash via ODIN
3) You can flash the KH3 version of CF-Root as well.

Hello,
you will still receive updates via KIES.
Unroot is possible with SuperOneclick. I have not tried so far. Every new firmware overwrites root. So if you root with ODIN and flash the rooted Firmware to the original one, KIES will allow to upgrade.
You could also use ODIA's insecure original kernels and use the ones provided from INTRATECH to have the original back on.
Never tried CF myself.
This phone is practically impossible not to root! Read everything thoroughly and take the dive, see you on the other side

Thanks~
Thanks for all the help! I did take the plunge ... and have no regrets!
I used CF's way, and have flashed back to my original stock kernel afterwards (courtesy of INTRATECH). Everything seems to be happy so far.
And now.. time to have some real fun with the phone
Thanks again everyone!
I also recently rooted with the CF-Root method. Congrats from a fellow HK/Taiwan phone user.

Xperia x10 mini how to root and install a custom rom?

Is there a tutorial for it? What you neet to do step by step. And can you use this tutorial http://forum.xda-developers.com/showthread.php?t=1682966 for the x10 mini to?
read several tutorials – if you’ve never done it before don’t rush into it
Misreading one line of instructions can mess the whole process up and leave you with a dysfunctional phone. Its not as daunting as it seems.. but you do need to know exactly what to do before you do it.... and while your doing it. Also check compatability with model numbers and software versions
for example my phone is an x10 mini pro but if I take the battery out its actually a u20i
Super one click rooted my phone without problems but i found i had to disable usb debugging and re enable it while it was doing its thing
youtube is also a good source for tutorials
I recommend this kernel and rom from NaA
if you have baseband update, the rest y very easy
the requirements are
bootloader unlocking
updated baseband
1.-search the web, update baseband to the exact model, e10i does not equal the E10A
if you install a firmware for another device, you may lose the 3G signal
2.- this post for unlocking Bootloader
http://forum.xda-developers.com/showthread.php?t=1481630

HI,
I rooted my sony experia mini e10i successfully using z4root app. now i have to unlock bootloader. what tool should be downloaded , i searched in google., many tools and many views for doing this. i am really confused. Please suggest any good and reliable tool to unlock the bootloader and please also suggest the steps for doing so. should i flash kernel and then rom or both at same time? in some tutorials they said,
1.use CWM ROM manager and flash recovery
2. poweroff and then power on , press back key
3. in recovery mode, wipe all cache,
4. install rom from sd card
Are these steps work fine for me? This is the first time i am trying these flashing custom rom. so am little bit nervous.
Please help....
Hello there.
As many of us, it's also my very first time that i'm attempting to upgrade my x10 mini's android version from 2.1 to 2.3.7 and i'm pretty worry of making it useless (bricking it? )
After spending hours and hours of reading several guides.. i was able to root my xperia, installed and log into CWM (v3.2.0.0-3) successfully. But now i have 15 different guides with 50 different steps to follow.. And now i am pretty stuck upon few basic (yes noobish) questions:
"Unlocking bootloader" means that, after installing CWM or xRecovery, we have to use the flashtool method or are we done with the unlocking part?
After getting done with unlocking bootloader, do we firstly install the new kernel and secondly the new Rom or the opposite?
Is there a way to recognize which Rom requires xRecovery or CWM before its installation?
Thank you in advance!

If you want a ROM that runs on a custom kernel you do need to unlock the bootloader, that's the only tricky part about the whole process
Which order you install kernel and rom doesn't make a difference, as long as the two are meant for each other. That said, it is common practice to install the kernel first and then the ROM.
xRecovery is (usually) only used in old ROMS that run on stock kernel, the 2.3.7 ROM you're aiming for will probably use CWM (Which is included in all custom kernels anyway). Which of the two is required is stated in the opening post of the ROM you choose.
Good luck
SmG67 you're a life saver! God bless you mate. Thank you so much for your fast, clear and accurate reply. The things i was worrying about make sense now. :good:
thnx

[Q] Need help on flashing stock

Hi guys,
I posted a question similar to this before, but did not get much reply.
I have a chinese Razr, and I would like to install an English stock 4.1.2 onto it. This is mostly because for some reason gapps do not work and I really do want gapps.
I have not flashed phones for two years so I have no idea what everything is. And it seemed like all these requires root. Which is my other problem: I cannot install root on this phone no matter what I try. Someone suggested to me that this was because someone had rooted this phone before in an unconventional way and this locked the phone for any future roots. And when I had updated to 4.0.4 I had lost the root and cannot regain it. I must have tried 20 different methods to root this phone already so I'm pretty sure this is hopeless until I flash a different rom.
In any case, my android version is 4.1.2 and system version is 672.300.384.XT910ChinaRetail.en.CN
And I would like to flash a stock 4.1.2 on it.

[Q] (help) Sony Xperia Ray Update to android 4 on modified phone?

Hi,
So I've done my best to read up on this but I'm absolutely terrified of Bricking my phone, so can someone please give me some advice?
I've got a Sony Xperia Ray running android 2.3.4 which is terrible and It won't let me use any decent apps.
I want to upgrade it to Android Icecream but I'm terribly dumb when it comes to phones, my talents lie in computers and I've been up the past couple of hours trying to decide what to do, I can't find a explanation that is noob freindly.
The reason I'm so hesitant is this phone was unblocked from a network to be compatable on any network, and I'm not sure if this effects the updating procedure?
When I downloaded the Sony PC companion it prompted me to upgrade my android but I'm not sure if this will upgrade the Kernel as well (Sorry if it's a stupid question).
I really need someone's help, I'm terrified!
Specs below:
Model: ST18i
Android Version:2.3.4

Sony's PC software will also update kernel if going to 4.0.4
sonys 4.0.4 is same or more laggy than 2.3.4 (gingerbread) also it still have a small storage, so u dont will have many space for apps.
if sony software fails to update, download the "flashtool" , with this u can flash firmwares manually. see in general section for tuts. firmwares can be downloaded here: http://talk.sonymobile.com/t5/Andro...y-Bean-ICS-Ice-Cream-Sandwich-and/td-p/154389
but the best you can do with this phone is to install some good custom rom. it will give the best experience on that phone.
to do so you need to check if you can unlock bootloader in service menu (google how to enter)
unlock bootloader: http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
lookup this fine ROM: http://forum.xda-developers.com/showthread.php?t=2543426

Rooting Help Please 5.1.1

Hi Ya'll and Happy New Year,
I need some help in rooting my Z C833. Before I tell you my ordeal here is the system details:
OS 5.1.1
Build 14.6.A.1.236
Bootloader: Unlocked via sony
Now i am not a advanced user when it comes to android stuff, I am still learning. All the talks and guides about rolling back and going to kitkat and flashing and recovering TA partion is kinda making me confused. I have seen many guides, i tried to roll back via flashtools, use king root to acheive root, install dual recovery then flash super user. This is the extent of my knowledge.
When i try to either ftf a pre rooted file to a 5.0.x fw i LOSE ROOT, every single time. Can someone help me out. What am i doing wrong?
For example I roll backed to (C6833_14.5.A.0.270_Customized_HK) installed King root, pushed (ZU-lockeddualrecovery2.8.23-RELEASE.combined) flashed (BETA-SuperSU-v2.49) and then went back to flashtools to ftf (C6833_14.6.A.0.368_Generic Telenor Norway) and i LOSE ROOT (ahhhhhhhhh):silly:
If there is no option for me to update to stock rooted rom, can i install a custom rom with a update fw?
Ideally, stock or custom, i just want to utilize the sound and screen mods on this forum for the z ultra, for that i need custom recovery, for that i need root :S
I know the answer might be very simple, but like i said i m out of ideas.................
Thanks in advance for your help.
anyone???
Flash kitkat ftf, root, flash pre rooted 5.1.1
Did you read here: http://forum.xda-developers.com/xperia-z-ultra/development/ub-14-6-1-236-stock-ftf-root-t3270850
Thank you very much pckoloji and RealityFails for your input.
I was able to fix it with the link provided : http://forum.xda-developers.com/xper...-root-t3270850
Thank you once again.
