[Q] How to go from MIUI to stock ICS on i9020T - Nexus S Q&A, Help & Troubleshooting

Okay the subject is clear. I upgraded from nexus one to a used nexus s today with miui installed on it. And as i saw billions of threads all around the web about bricked phones after update to ics i thought it would be good to ask.
I have miui and i just want to upgrade to stock ICS and want to keep the root. Please tell me if there is some special instructions i should follow.
Thanks!

Since you are coming from Nexus One, I guess there is nothing special.
* Get the full OTA ROM for your phone model from the link in my signature
* Flash it via CWM recovery
* Get the updated su and Superuser from here (download the Superuser-3.0.7-efghi-signed.zip one)
* Flash it as usual
* Done!
Note: If you booted into ICS before flashing Superuser package, you will have to re-flash CWM recovery again because the recovery will be reverted back to the stock one.

So there is nothing special that i have miui thing installed. I will just install IC via CWM like i have ginger bread on my phone.
Is there an easy step by step guide for all of this, i didn't make an update for a long while so i kind of forgot things?
thanks!

just flash a rooted stock rom, if you install stock then you will lose root and recovery!

okay i updated just using the stock 4.0.3 rom. it was stuck with the dead android screen. then i used recovery to flash the same rom. it is working flawlessly. i had to install just the cwm recovery. other than that i didnt loose my root.

[Q] I need some answers about Nexus S

So I bought Nexus S from second hand recently mostly because it will get official ICS support from Google.
So because it's second hand buy, I really don't know if I'm using original bootloader, kernel, radio etc.
It's rooted (because I have Superuser app), I think it has stock 2.3.6 android (build number GRK39F) and kernel version 2.6.35.7-gf5f63ef, [email protected]#1.
Can someone who use stock android and original kernels confrime to me that this is right version?
I really want to update to ICS using incremental update which I found here (http://forum.xda-developers.com/showthread.php?t=1445635) but I'm affraid to don't screw something because of bad experience when I radio bricked my desire
Can I update it to ICS or I need to do unroot or something?
Just download the correct stock ICS rom for your device (if it is I9020T or I9023) ,put it on the SD root and then flash it using the stock or CWM recovery and be done with it (if you need the ICS)
most likely you won't be update by OTA because you are rooted (system file verification will fail)
just download stock ICS ROM and flash it ...
Ota will install fine if its a stock rom with just root. The update script basically checks that everything that should be there is there . If there is something else in there like su it don't matter.
flashing a new rom is the best way to go if you have cwm installed already
I succesfuly flashed ICS and first impressions are very good.
But I think I lost recovery...

flash a CWM recovery via adb , or there is TWRP recovery in DEV section , which is very good .

revert back to stock to update to ICS

Hi , few months ago i rooted my phone ( did not install any custom rom) only the clockwork recovery mod (somethin like that) i think , so now i wanna go back to stock so i can install ICS, i download my RUU and a pg58IMG.zip file(what is that for) , so the problem is that my phone is connected in charging mod to my pc , and debugging is on , but adb devices cant read it , what should i do ?
Please any additional info would be appreciated , thank you alot
as far as i know, if you want to install stock htc ics, you just download the original RUU, run setup and plug in your phone, you don't need clockwork recovery or anything else like that, just follow the steps from the HTC RUU setup...
If you have received the FOTA updated just changed the recovery to stock HTC Recovery. And flash or run the OTA update. I use this guide to get back to stock HTC Recovery it may also help you [GUIDE] Get Stock Recovery/Install OTA Updates without losing data.

[Q] Custom ROMs won't boot

Hey guys, I've seen this issue before yet I've tried everything in a few threads now but have no idea what is happening,I have tried using search function yet no solution has fixed my problem.
Problem:
When installing custom ROMs the installation goes fine. I put the ROM on the sdcard, follow instructions for flashing e.g wipe data/cache etc and then flash GAPPS. However I get stuck on the boot logo of every ROM. I've tried both TWRP and CWM recoveries, both with no luck. Also tried not flashing GAPPS and just trying to flash the ROM to no avail.
Current state of phone:
The phone is currently running stock firmware via downloading factory image and flashing in boot-loader : stock boot, recovery, system image etc
The phone works fine when rooted on stock firmware. E.g no custom rom yet rooted.
Could really do with some help guys, any ideas?

same problem simple solution another user informed me of.
simply donwgrade to 4.3 JB stock rom through fastboot. Then you are able to flash a custm rom from the 4.3 stock rom.
Its crazy i have to do this but it worked for me, now im running the xperience rom which is a rom based on 4.4.2 kk.
the 4.3 android stock firmwares are linked somewhere in the FAQ's as well as the guide to ffastboot lash it.
peace.

Hey man, worked a charm thanks!
For users who may have the same problem:
After flashing 4.3 onto the device it did NOT boot.
- However I then went into the bootloader flashed custom recovery, I used cwm.
- Then I went into recovery, used adb to push the rom and gapps onto sdcard
- Full wipe and then installed rom. Then installed gapps
Working fine.
Cheers chairsz :good::good:

I'm trying to avoid another brick PLEASE HELP

Howdy y'all. I bricked my old G2 D800, I don't want a repeat with the new one. I tried doing all the research I could. I have a new D800, 10d, 4.4.2. I want CM11, tried reading the threads on that and custom recovery. I just need a little help to make sure I have the order of operations down pat before I crash another. I've rooted and flashed ROMs before, but not with th locked boot loader and security AT&T has.
Please just correct me if I'm wrong. Through the threads I have read I believe this is what I am to do.
1.) Flash my 4.4.2 back to 4.2.2 using LG FT
2.) Root using IO23
3.) Download Flashify & install TWRP 2.7.7 with Loki
4.) Follow steps to install CM 10.2
5.) Follow steps to install CM 11
Of course make backup once 4.2.2 plus root and TWRP is achieved before trying CM. I just want CM like I've had on previous phones. Thanks in advance.
All is good back to being ROM junkie. Anyone who does read and wishes to flash custom roms and get custom recovery on KK. Obtain root via IOroot25, then use AutoRec Recovery Installer for TWRP recovery.

Easiest way to reinstall stock rom

Hi all as title states my moto g is downloading the new 5.0 update but during install it says error and switches phone back on with no changes made. It was rooted and custom firmware was installed. Since then uts back to fully unrooted, stock recovery is reinstalled and bootloader is still unlocked. However still it errors a quarter into installing.
So i have come to the assumption that it is best for me to revert/ reinstall the stock 4.4.4 rom back on and try updating after that. However seen loads of complicated methods on how to reinstall the stock firmware onto my phone so want the easiest way if possible.
In attatchments is the info from the current stock rom that is on the phone (will state a custom rom has never been installed to the phone always been stock) and i have downloaded the following to put onto it:
XT1032_RETAIL-GB_4.4.4_KXB21.14-L1.40_36_cid7_CFC_1FF.xml.zip
Ive tried using the mototools v3.1 and does abserlitly nothing non of the commants work or do anything with my phone.
So which is the easiest method?
Many Thanks
major problems!!!!!
Stock recovery installed to phone. Started update it was installing and got to 3/4 of the way through, errored, restarted and not goes in a loop saying no command!
Phone will not switch on!!!
Why has this happened?
If fastboot is too convoluted - using a custom recovery, flash one of these zips:

What update were you installing when it errored?
