Help!Wifi issue after upgraded to 4.0.4

i can't connect wifi after upgraded to 4.0.4
i tried to reset factory data
but it doesn't work
please help!!

We're going to need a bit more information before we could begin to make suggestions.
What verison of the Nexus S do you have? (European, T-Mobile, Nexus S 4G?)
How did you do the update? (OTA, ODIN, Flash Via CWM)
Are you unable to turn wifi on? or is it on, but you just can't connect?
If Wifi is on, can you see any wifi access points under the wifi menu?
If you can see the wifi access points, but not connect to them, does the phone even attempt to connect, or does it just hang there?
All of these would be very helpful in diagnosing the problem.
(My gut feeling though tells me that you will just have to re-flash the 4.0.4 update. IN order to est determine how to do that though, we will need answers to the first two questions.)

Model number: Nexus S
Android version:4.0.4
Baseband version: I9023XXKI1
Kernel version: 3.0.8-g6656123 [email protected]#1
Build number: IMM76D
I received the upgrade software from google on the device, and then installed directly.
Able to turn wifi on, but cant see any wifi access points under the wifi menu
Thankyou so much

You can try another ics 4.0.4 on the web (mine is from samfirmware) and try reflashing...

Anyone can tell me how to reflash my device?

Is your bootloader unlocked? if it's not, unlock it: http://forum.xda-developers.com/showthread.php?t=1007782
You can follow the steps till part 3
After that, get a custom rom: http://forum.xda-developers.com/showthread.php?t=1399035
This one's CM9. (I've tried many but always come back to this)
Just follow the instruction in the link.

Thanks ej8989!
Thank you so very much. hopefully I can get it working somehow now.
Just to make sure. I get everything right. my phone says it is i9020AUK...so it is i9020a right?

bought tablet, and now?

Hello folks,
Just bought the TF300T Tablet yesterday.
It came with Android 4.1.1 preinstalled
Kernel 3.1.10 from Nov 22 21:27:42
Build No: JR003C.WW_epad-10.4.2.18-20121122
I read through many threads about rooting but i have some questions remaining:
How do i find out if my bootloader is already the JB-one which can't stay locked to root the device?
I mean that i can't use nvflash.
At the beginning i want to stay at stock rom, only rooted for removing ads purposes
After what i have read i only have the following options:
a) Install the already offered update to 4.2.1 and use Asus Bootloader Unlock V8. (don't want to unlock)
b) Stay on 4.1.1 and Use Unlock V7 (don't want to unlock)
c) update to 4.2.1 wait if i can root without unlook bootloader sometime
So if anybody haven't an other option i choose to update and wait. am i correct?
Thanks :good:

Now there is no option to get your installed or newer versions to be rooted without unlocking the device.
All your options are correct.

Well your on 4.1.1 which is jellybean so you do have the jellybean bootloader and nvflash is not possible. The only way to root your tablet will require an unlock and custom recovery.

I'd suggest you to keep it stock for some time, so you would avoid some hw failures and warranty problems. I am happy enough with it, it's not perfect but ... nothing is
Proud owner of an ASUS TF300T stock and the "old faithful" SGS i9000 powered by AndroSlim

Since latest update it runs smooth enough

I chosed option a) and updated the tablet. After flashing Asus v8 apk i get struck with correct install of twrp recovery.
I don't see any files. I downloaded the official file from their homepage and read that there is a patched one in a thread.
gonna try this one this evening.

cleanROM is working on a very nice stock ROM with tweaks which is something you might want to consider if you decide to unlock

[Q] Got my phone unlocked - but they rooted it - can I unroot?

I recently had my Orange Galaxy S2 i9100P unlocked by the local phone shop.
The unlocking worked fine, but I have now noticed that it has been rooted too.
It has a superuser app installed, which he said he didn't realise it had installed.
Not sure that I want it to be rooted when I sell it as it might put off potential buyers.
So I called the shop and asked if it has to be rooted to unlock it and he said that it does.
He said that the other way to unlocked it is to use a code but that system is currently down (the website that gives out codes) and it would cost £26 instead of the £10 that I paid to have it unlocked using root. I asked him if I could unroot it by flashing with the standard Orange firmware (using Keis) and he said yes I could and that would unroot it. When asked that if this would then lock it again he said that no it shouldn't, but he didn't seem too sure about what he was saying.
So some specific questions:-
1) Did he have to root it to unlock it?
2) Did it have to be left in root once unlocked?
3) Can I unroot it and return to standard firmware (using Keis) and it still remain unlocked?
4) If the answer to 3) is no, then can I delete / uninstall the superuser app?
5) When I run the superuser app, there is a temp unroot option. What does that do? Can I use that to unroot it?

1. Yes root was required to unlock from the carrier. Or else you had to pay full price to get the unlock.
2. Not exactly! If he made a permanent change then no need, But if he's using something dependent to unlock it then it needs to be rooted.
3. Not sure, cause if the stock Orange firmware finds the phone as locked it might re-lock it again. So there's a risk. If you can find a fresh carrier free firmware for your model why not flash that?
4. I used SuperSU there's an unroot button there but nothing that says 'Temporary'. But if the root binaries are once flashed I'm not sure that gets rid of it.
Just trying to be helpful.

How do you mean? Are you saying that there is another appliocation that is running that is performing the unlock and that needs root to do its stuff?

That is an option. But Last time I looked (a few years back) I couldn't find any i9100P specific unbranded firmware. There was i9100 firmware, but that didn't support the i9100P NFC chip.

My app is just called "superuser" and is at v3.1.3. I suppse that I could try the temp unroot and see what happens.

Yes, I'm saying there might be some app keeping the unlock alive. Cause that's how I unlocked my iPhone 4, quite a lot of times. :3
And you should search again for unofficial rom.
And also try the temporary unroot button.

Rightho, I have now moved over to the S5 and I would like to get my S2 ready for sale.
Someone mentioned earlier that Keis might not recognise the device. Well you are correct it doesn't and will not let my flash. I does not recognise it as a Samsung device.
So I would like some generic I9100P firmware that supports NFC.
I would also like to unroot the device.
Current firmware is V4.1.2
Baseband version is I9100PBVLS2
Kernel is 3.0.31 - 1246097
[email protected] - 109 #3
SMP PREEMPT Tue Jun 4 15:49:20 KST 2013
Build number is JZO54K.I9100PXXLSS
I do not get a yellow warning triangle so I assume that it is a secure kernel.
So can anyone help me to:-
1) Unroot the device.
2) Get it so that Keis will talk to it again.
3) Keep it unlocked
4) Get a secure kernel if mine is insecure.

Flash a custom recovery through Odin and then backup your current Rom. And then find flashable-zip official firmwares and then flash and see results. If anything goes wrong revert back to the old firmware.

The solution seems to be to download and install firmware XXLSU Android 4.1.2 Jelly Bean.
This will install a generic unlocked stock ROM and generic firmware, which is just what I need.
See here.
w w w.ibtimes.co.uk/galaxys2-i9100p-xxlsu-android412-jellybean-update-install-501998
However, I am not able to find the update ROM / Firmware files as all the links in all the websites that I have found are all dead.
I have founf some working links but this is for Spanish / French versions. Will these be OK?

Keep in mind to use the firmware with the right "MODEM" version. SamMobile offers the firmware version(s) you are looking for. BUT don't risk flashing another firmware, if its much more easy. Install "SuperSU" from the play store. Open it an switch ROOT to "SuperSU", you will be prompted to uninstall the current superuser (root). Accept it. Reboot your phone. Open SuperSU and perform "Complete Unroot". Thats it

Ok that will unroot it but stay with orange firmware and be re-locked to orange?
I was wanting a generic ROM and firmware that supports NFC.
SamMobile has the I9100PXXLSU firmware which I believe I need. However, it has 2 versions:-
Date Country/Carrier Version PDA CSC MODEM
2013 August France 4.1.2 I9100PXXLSU I9100PXEFLS3 I9100PXXLS8
2013 August Spain (Vodafone) 4.1.2 I9100PXXLSU I9100PATLLS6 I9100PBULS3
Should I be concerned about the carrier / country?
You say get the correct MODEM version but how do I know what the correct one is?
My current details are:-
PDA: I9100PXXLSS
PHONE: I9100PBVLS2
CSC: I9100PPORALS6
Please can someone just tell me where I can get a generic ROM / firmware and tell me which one I should be using.
It all seems to be riddles and cryptic clues.
I am confident of downloading the ROM / firmware using ODIN, but I just want to know what to download.

Vodafone firmware is Vodafone branded, so i won't use it as its probably highly customized by vodafone. The France version should not have a branding. You can check your modem version in Android: "Settings-->about Phone". If you get you right, you want to sell a branded phone as unbranded and potentially next owner may not know. sounds not very good

I was just trying to get rid of all the ornage bloatware. If someone wants to use a different network operator, they might not want all the orange stuff on there. I was certainly not wanting to trick anyone. I suppose I could just unroot it and leave it as it is (it is obviously an orange branded phone as it has orange logos on it). Or I could just download the standard orange ROM / Firmware and return it to stock. My worry is that this will lock it again. I keep asking this question but no one seems to give me a straight answer if it will or not. Maybe it is an unknown. As I am a newby I have no idea.

I suppose its hard to say, because no one but the shop owner exactly knows what method was used to unlock the phone. Thats the reason why there is no guarantee that the unlock survives a firmware flash. If you just want to get rid of unwanted apps, you can use "Titanium Backup" to uninstall whatever you want. I would never use a non rooted phone again, so may be the new owner is happy that its already rooted

Yeah this works, if you really wanna get rid off the orange BS. Just uninstall all the BS with Titanium Backup and then simply unroot. :3 And the device fresh and unlocked and not rooted without the BS. :3 And everybody's happy, right?

[XT1039] Developer "noob" questions

Hi everyone, I'm new here.
The XT1039 that I bought last week is my first Android phone with an unlockable bootloader, so I have a few questions before I do anything with it. I am a software developer and I have some experience with Android system hacking on my Asus TF700 tablet, so I do know what adb and fastboot are - my "noob-ness" is highly device specific.
Speaking of fastboot, what exactly is different with mfastboot compared to regular fastboot? Only the support for the "sparsechunk" images? Or does regular fastboot not work at all on Motorola devices?
Is the source code for mfastboot available and where do I find it?
Exploit-based rooting method
For making a backup of current partitions, it would be handy to get root before unlocking the bootloader.
The stock ROM version my phone came with is this:
Code:
ro.build.description=peregrine_reteu-user 4.4.4 KXB21.14-L1.56-1 1 release-keys
Linux version 3.4.42-g09ca493-00001-g5aeebdc ([email protected]) (gcc version 4.7 (GCC) ) #1 SMP PREEMPT Sat Sep 27 15:10:40 CDT 2014
so I assume that the towelroot exploit has been already fixed in this version.
I searched for alternatives but found nothing - did I miss it or is there just no working root exploit?
Stock ROM images
I've seen the stock ROM thread, but I've not seen an official download source for them.
Are these leaks from official Motorola servers? How can I verify the authenticity of the stock ROM downloads,
or where can I find official downloads?
Unlocking and upgrading
My goal is to either use
a cleaned up 5.1 stock ROM or
CM 12.1 or
OmniROM.
My plan for the next steps is:
unlock the bootloader
install this stock ROM: XT1039_PEREGRINE_RETEU_5.1_LPB23.13-17_cid7_CFC.xml.zip to get the current (.1A) bootloader and a matching stock kernel and system
build a current TWRP (based on device tree by @Somcom3X) and install it
Make backups of device-specific partitions
Install SuperSU
- Is any of this a bad idea, and why?
- Would there be any reason to keep the old bootloader? (I've read that there are at least 2 partially incompatible bootloader versions and that there is no way to downgrade.)
- Does the bootloader incompatibility only produce screen flicker or are there more severe issues?
Kernel source
I have neither received kernel source with my phone nor a written offer from Motorola. However I found
https://github.com/MotorolaMobilityLLC/kernel-msm
which even contains full commit history (nice!) and a lot of confusing tags, none of which match exactly the ROM build number?
Is there anything unusual (as in, different from other Android devices) that I need to do for compiling the kernel and boot image?
How to brick it
It's always good to know what *not* to do. From what I've read in the forums, I should never do:
run "fastbooot eerase all"
erase partitions that contain device-specific info (hob, dhob)
flash a ROM with the wrong cid
flash a bootloader not designed for my device or otherwise mess with the bootloader
accept OTA updates without having a consistent stock setup
Anything else that I should be aware of?

Pinging a few RCs who claim to support this device - @DC07 @matmutant - please help me get started with this new device.

To what i've read you are right on the overall (i don't know peregrine specific things, since i only own XT1032 8 and 16GB variants)
i never tried mfasboot, and instead used fastboot bundled with the Android SDK with no issues (bootloader flashed nicely and so)
Root
The only kown way to root is having an unlocked bootloader here
Stock ROM
ask @lost101
How to brick it
i don't see any other way at the moment, maybe others will ?
If you see anything that is unclear in the FAQs tell me, things that look ok for people using the device for a while might not be understandable by newcomers
PS: don't forget to "backup" your IMEI to prevent issues too
