[Q] Unrooted stock bootloop - need help

Recently my Nexus s started bootlooping.
First it was happening if the phone was powered off due to finished battery, now it happens every time i power it off.
What happens is, it bootloop on the google logo. In order to over come that i pull the battery out and turn it back on. After a few time (3-10) it would start up normally and not bootlooping.
I run stock 4.0.3, not rooted.
Anyone has a clue ?

my only suggestion is maybe a factory reset, you might have some corrupted files somewhere. but, my fear/concern is that your internal sd storage card might be going.

And if a factory reset didn't work, I think you'll have to use ODIN to flash stock 2.3.6 ...

What is lost on factory reset ? only the OS and installed apps, no SD data right ?

You think it might be a result of ICS upgrade ?

Yes factory data reset only deletes all data on your phone not the SD card.

Okay, so i did factory reset and i'm still stuck on the bootloop. Need to remove the battery and turn back on until it doesn't bootloop.
Actually what happens is the google logo appear, then for a moment it turned off and comes back again.
simms22, why do you think it's internal sd damage ?
TheMatrix246, what's ODIN ?

Guys, you think if i root and switch ROM it could be fixed ?
I would appreciate some help here a bit lost.

One last thing before you contact Samsung:
Download Nexus S [i9020T/i9023] 4.0.3 Full ROM and copy to sdcard as update.zip
Go into bootloader
Recovery
Data/factory reset
Install update.zip (reflash all files of ICS)
Reboot and hope it works out fine
If this doesn't work for you i highly doubt rooting and changing ROMs will. This will reinstall the entire OS (format and install /system), bootloader, radio, kernel and recovery.

Do i need to be root user in order to do that ?
And just to make sure, this Full ROM is for i9020T ? correct ?
(mine says only GT-i9020 on the back, bought in Carphone Warehouse in England).

Yes, i9020T. If you get 3G with Orange, and you have the SAMOLED screen, you have the i9020T (and to my knowledge, 9020 on the back signifies i9020T).
Also, i don't believe you need to be root to do that. I'm pretty sure you can flash the same version ROM from stock recovery as long as it is signed, just not older versions.

First, thanks guys for the help.
After first doing the factory reset, it seemed the bootloop happens less often. At first i tought it was solved but then it rarely (1 to 5 reboots) yet happened.
Today i installed the Full ROM Harbb suggested and so far i have no reboot issues.
But i after the installation i saw OS wasn't reset. Does it suppose to (not) happen ?

You're welcome. Also, all that file does is replace everything in the /system partition (OS). All apps besides the defaults that come from the factory are not in that partition so are not affected. Hopefully your problem is fixed permanently

But it's generally recommended to do a full wipe when switching ROMs. It could be that you encounter other problems because of the ROM change without wipe. But you could also be lucky to have no problems. Just to remind you, when you encounter something wierd.

Problem is still there ....
Hi guys,
First thanks for all the help, but the problem still there.
I did the upgrade using the Full ROM as Harbb suggested. For the first 10-12 times i rebooted (i rebooted again and again) it was alright, booting successfully ... but then it stated occasionally to bootloop and now it does it almost everytime. usually takes up to 10 times i remove the battery and start the phone so it will start up and not bootloop.
Also, I'm sorry the taking so long to respond, the nature of the problem compelling me to test it for a few days so i will know if it works or not.
Should i root the device ?
If so , how do i replace / rewrite the boot program ?
I would much appreciate any suggestion.

I had a similar problem, bootlooping, stuck on Google logo when running 4.0.3 in the end I took it back to carphone warehouse who repaired it and now it's ok. I found that heating it with a hair-dryer made it stop bootlooping (but that's what worked for me). However the repair seems to have fixed any issues and its all OK now.

My problem is i bought the device also in carphone warehouse in the UK, but i live in Israel. Meaning i will have to send it to them by air-mail.
By any chance they mentioned what was the problem ?
also did they give you a refurbished device or a new one ?

Sorry for slow reply - they said they 'flashed it' and it came back unlocked but I believe its still the same handset and I've no idea how they did it soz.

Hey, thanks for the replay.
What does is mean to flash it ?
How do i do that ?
You noted it was returned unrooted, was it rooted before ?
Again thank you all for the help.

To be honest I'm a novice to these terms but know that they unlocked it(it was not unlocked when sent off) and reinstalled os 2.3.3 after a complete wipe. Details of how to unlock and flash (install a different os) are on the forums. If you follow the forum advice precisely the instructions work. I am now running a CyberGR rom of ics 4.0.3 that runs smoother than stock ics . Again found on these forums. Hope this helps.

wifi error on every ROM

long story short, my phone was shipped with prerelease software. After rooting and flashing a customer recovery, my original nandroid was corrupted.
The only option for me now is custom ROMs, but unfortunately my wifi gives me an error on every single ROM available.
Anyone know of a quick fix?
The only thing i can think of that would solve the issue is to possible flash the stock US ROM once it's available, then hopefully that would fix my wifi issues and i'd be able to flash to any other ROM with no problem.
Alternatively - could someone please post a flashable ZIP of the stock ROM, or at least post a stock nandroid that i would be able to restore onto my phone to see if the wifi issue gets resolved.

Did flashing the stock img work

I have a fix for you. I'm releasing it tomorrow though.
I'm releasing a stock T-Mobile nandroid final firmware and newest software.
I'm also releasing a rooted version.

After doing a bit of reading, it seems as though some people have having similar issues. The exception is that theirs is doing this while stock, and updating their router firmware fixed the problem. My phone connected to my router perfectly fine while stock...the problem didn't occur until i flashed the first custom ROM.

It's because all roms now are based on European firmware not T-Mobile firmware.
Tomorrow I'm uploading the first ever T-Mobile Rom and it'll fix everybodys problem.

Definitely sounds like a firmware or driver issue. Have you tried resetting your router or updating its firmware? Also, what kernel version are you running.

tried connecting to a different router on update stock firmware and teh issue still exists.
I was hoping that with the stock TMO-US ROM the problem would be fixed, but unfortunately not.
Now i have really no idea. It's impossible for me to live without wifi on my phone for good.

Do this:
1. Delete /data/misc/wifi folder using a file browser.
2. Clear cache using recovery. Reboot. Wifi will regenerate its data.
3. Try wifi again.
Let me know if this works. It's a shot in the dark so I don't know if that's gonna work for you, since you already seem to have performed a fac reset.

Thanks for the tip, unfortunately this didn't work either. I'm totally out of ideas at this point. Might just end up exchanging the phone and paying the out of warranty fee if they find out the boot loader was unlocked. Not really sure what's left for me to try.

I did within ten minutes of you posting it. Unfortunately it did not solve the problem. I thought that would be the fix...

One thing I didn't notice was a clear description of the problem. Please describe what your issue is. You say the wifi gives you an error. What does that mean?
Please describe everything in detail from start to finish, before trying to return it.

WiFi will turn on, display available networks, once a network is selected it will not connect and then says "error"
then after about ten seconds the phone will reboot, then reboot after it turns on. never-ending.
only way to have the phone work is to do a master reset, but the problem starts again when you attempt to.connect to WiFi.
also the phone will not stay off when stuck in the WiFi reboot loop. if i choose "power down" it will turn off, then turn back on within 10 seconds.

That sounds very very strange. Almost like a kernel error (unlikely since kernel is included w/ ROMs), a radio issue (more likely), or a hardware issue (most likely, in my opinion). If you've already done a full wipe and wiped /system and /sdcard to be sure, then it sounds like you've done your due diligence.
At this point you might want to go ahead and reflash the stock ROM (see Reviewer's post with a nandroid of the stock ROM), reflash the stock recovery, and relock the bootloader. Unless someone else can chime in here. Also, if you return it, there's no promises that they won't look for TAMPERED or anything in the bootloader, so beware. The important thing is to have the stock software and recovery loaded and it relocked. Then they can flash it in the store, and it'll probably fail, in which case they may replace it.

Yeah i'm clueless. I've literally done absolutely EVERYTHING that i could imagine to fix the issue.
I actually work for T-Mo, we dont have any abilities to flash anything in store. Also exchanging the phone is a little bit more difficult for me, because the phone was not purchased through tmobile, it was given to me by HTC a week before launch.
Either way, I'm going to reload all the shipping stuff when i get home tonight then go ahead and try to process an exchange. Worst case scenario they will charge me ~100 bucks as an out of warranty fee. (due to having the *TAMPERED* logo on the bootloader scren. Although I'm fairly certain they don't check that, they shoudl only check for physical/liquid damage. I have processed many exchanges for rooted customers, who had manufacturer defects.

also another thing i just noticed, my baseband is: 0.15.31501S , but my friends retail version is 0.16.
any way for me to update this?

Early Adopters
I just got the One S myself and I'm a bit forlorn from the lack of available ROMS. Then again when I was in the Apple Ecosystem, there was no ROMS, just tweaks so different environment different timelines I guess.

Not sure if it can help in this case, but this solved my wifi error problem.
I had a "wifi error", my One S coudn't connect any AP.
The problem was a bad permision on the file /data/misc/wifi/wpa_supplicant.conf.
Logcat gave me that :
"Cannot set RW to /data/misc/wifi/wpa_supplicant.conf"
So, using Es Explorer (as root), i changed the chmod of this file to rw-rw-rw and wifi started to work again. (no reboot needed in my case).
Hope this help.

[Q] Factory reset?

So I'm S-off, Firewater, SuperSU, CWM, stock software, I have not loaded a ROM, fastboot flashed the nohbootimg firmware update, added the HTC browser, and flashed the OTA-killer.
Can I do a Factory reset without it messing something up? I'm having 3 issues that I want to see if a reset will fix, one is my alarm clock keeps turning itself off, another issue is that when I turn the phone on it seems to take a long time to "Prepare Sim card" , and the last issue is that I get a email "login failed" notice which is poping up before the phone starts seeing the data connection.
Thanks

If you are simply stock and rooted... you can factory reset using CWM without any issue.
Worst case scenario if you are backed up...
http://forum.xda-developers.com/showthread.php?p=52115727

Since you have not installed a ROM I would think a factory reset would be a good first step. You will probably lose some if the customization you have done, but I wouldn't think you would lose root or anything like that. I believe a reset will just wipe the data partition ( maybe dakvik and cache as well).

Thanks! Just curious, I'm trying to learn as fast as I can , how does CWM reset differ from the the stock one?
And do you think that the CWM reset could help with the issues?

They both typically wipe the same partitions however the stock recover also resets some radio elements which is why you will always see me suggest to someone with radio issues to do a factory reset from stock recovery.

I used the reset in CWM and I'm going through the setup now, I guess we'll see if this helps. Thanks guys!!!

Well the alarm is staying on so far and I'm not getting the email login failure but I think I lost my CWM, guess I'd better reload it.

Interesting, I can't seem to get into my hboot mode? hmmmm
nevermind, I'm a dolt, forgot to turn off fast boot and I Still have CWM but when I select reboot I get a message "Root access possibly lost. Fix?" Anyone know what this could mean? Should I Pick "Yes - Fix Root" . I'd assume so, what the heck lets see what happens. lol

Phone encrypted!!!

I was messing around with CM and I went into twrp to restore a backup and now my phone is locked. Can anyone point me where to go with this?

If you encrypted your device they only solution to decrypt is to factory reset.

You need to search around here. This is a documented issue with aosp ROMs. Someone put out a command line fix (i think it's in the noon-carrier-specific m8 forum) or you can use the ruu files found in this forum.

I have had this twice now, i fixed it by formatting data in twrp then factory resetting and restoring a backup from my sd. I lost all my internal storage.

factory reset dont work either sorry were both S.O.L. unless u have insurance then just "loose ur phone"

I'm back guys!!!!! I ruu'ed in fastboot. Weird thing was when my phone booted back up it still had supersu!!!!!! That made me happy. I then flashed twrp through flashify and restored a back up I made before this whole fiasco. Thanks again for everything!!!!
So you returned your phone to Verizon over this? If it turns on you can fix it.

So you sent in a phone that you broke and that can be fixed but are too lazy to research? And this is why companies lock down bootloaders. If you cant do basic searching, then dont root your phone.

[Q] Bricked xt925 - read-only eMMC ?

Hello,
Since yesterday my phone is crashing about 20-30 seconds after properly booting. I can unlock the phone with my lockscreen pattern, I land on my homescreen but process like Google Play Services goes like "x has stopped working".
On CWM I've erased /system and /data and then reflash a rom (Slimkat or CM), Erasing and flashing process on CWM seems to work as planned but when the phone reboot it's still on Slimkat with all my datas, like if nothing have been done in CWM.
So I've rebooted on the bootloader and tried a "fastboot -w", again the process seems to be ok on my pc but when the phone reboot it is still on this f**ked rom with all my datas, like if fastboot have done nothing.
I've tried to flash an up-to-date CWM, same thing again.
I think the eMMC chip are deeply corrupted, they say any writing on it is ok but in fact they are read-only, which may explain why all the process are crashing after the boot and why flashing seams ok but are useless.
What do you think XDA, andy idea about my problem ? Do you think it's an Hardware issue or what can I do to solve it ?

if infact it has gone read only as has happened to some other users, there is no known fix. all known angles have been explored, even with input from a developer.
if you find a fix, post it, it may help others.
most likely, you will need a new phone.
