[Q] Root and Cant open serial (com) port. - Galaxy S III Q&A, Help & Troubleshooting

I have a GSM version of the Galaxy S3 and directly after buying it i rooted the device using CF-SGS3-CWM-v5.5-v1.2.tar
Everything was perfect but yersterday I got an OTA update from Samsung. Instead of installing I read some threads and the general idea that i read was Root+OTA could make some problems. So one should unroot it.
Instead of unrooting it the conventional way as it is written in many forum tutorials I played around with the SuperSU App and could not help myself clicking the option: Unroot.
So now I have an unrooted Phone (no root applications are working), with flash counter at 1.
I tried to download the OTA update from Samsung but am getting an error messege and OTA update is then aborted.
My idea was that it probably is due to maybe unconventional rooting or maybe the flash counter. So I tried to root my device again using the same data that I used to successfully root the first time. I am getting an Error:
"Cant open serial (COM) Port"
I tried on different USB connections and using different USB cables...But still the same problem.
The update that i wanted to install from Samsung was installed using Kies. Kies did it without any problem. So I am assuming that OTA did not function because of problems with OTA update mechanism.
So as it stands now:
-I have a device with no root, a flash counter at 1. I want to successfully root my device again but am not understanding why serial (COM) port cannot be opened. As u might have guessed, I am new to android and easily understandable replies would be much appreciated.

Multiple posts say OTA fails on rooted phones .

Unroot Bell Mobility SG2 I9100

My girlfriend bought said phone from kijiji (online) and later found out the phone was rooted; no problem really. Now the phone needs to be sent in for warranty and I'm having some trouble unrooting it..
I read all the faqs, it's the same process as rooting essentially? I flashed the stock kernal that I found, using Odin3 v1.85 and assumed it worked. However Kies will still not connect and when using the Root Check app it says the phone is still rooted.
I think I may be using the wrong Kernal.. I hate to ask for handouts but could someone direct me to the link or give me a suggestion of why this might not be working?
Also quick question; we think the original owner rooted it to unlock the phone via the unlock app, so will the phone still be unlocked after unroot?
Thanks for the help guys!
A few questions:
1. What ROM do you run?
2. Is your custom binary counter 0? (check in download-mode)
3. Try this: install the terminal emulator from the market. Then execute the following command "su". What happens? If you get the super-user prompt or the $ becomes a #, you are still rooted for sure.

Hey, thanks for the reply
1) I used the rom from this thead.. I just CTRL+F for BELL and downloaded the link beside it http://forum.xda-developers.com/showthread.php?t=1075278
2) Download Mode displays this in the second line:
PRODUCT NAME:GTI9100
CUSTOM BINARY DOWNLOAD: YES (1 COUNTS)
CURRENT BINARY: SAMSUNG OFFICIAL
3) I did get the superuser request when I typed "su" into terminal client.
So it's official! I'm still rooted!
Flash stock ROM. Device will remain unlocked.

Remember that the custom binary count is not 0! I don't know if they do it, but this could be a reason to refuse a repair. Before I send mine back, I've reset it.

Yes, I'm aware that this isn't the accepted way, but it DOES work even with a custom rom & rooted!!
You MUST have Kies full installed on the desktop/laptop and make sure you're updated to the latest version.
1) Boot your note into download mode
2) Connect your Note to the laptop with factory USB cable
2) Launch Kies on your desktop (full version)
4) Choose Tools, Firmware upgrade & initialization
a) While in download mode, pull battery and enter the S/N & model name (ALL CAPS!!)
b) It will prompt to initialize to original settings. Click "YES"
c) It will prompt to initialize the latest version. Click "YES"
d) It will download the firmware upgrade components (DO NOT DISCONNECT THE DEVICE!!)
5) It will prompt for firmware upgrade and initialization.
a) Click check box for reading above information
b) Click your choice if you want your information saved on Samsung Kies corporate servers (I choose WITHOUT saving).
Just kick back, wait and the phone will update to the original out of box software with the latest updates already applied. No issue with anything, no tripping of the flash counter, and Samsung/AT&T knows now different (if you tripped the counter back before performing this, or performed the process of installing CWM recovery through ADB as to NOT trip the flash counter when changing recovery).
This is the EXACT process I did, and had an AT&T tech verify and it's not detectable I was rooted, and was running a custom ICS ROM. Now, I will qualify that I DID the Recovery installation with ADB so that I didn't trip the counter with the Recovery installation. So if they are able to check the binary information to detect modification even with flash counter reset, that's out of my hands and can't confirm or deny.
This is ONLY to reset to factory GB Latest & greatest for performing OTA/Kies update of ICS when it's finally released.
Tagged, thanks.
Thanks for this. I just got my first android phone a few days ago and needed to go back to stock to return for a new one. I upgraded to ics, then recently flashed back to stock, but my baseband never changed and I was stuck with two on the counter. I'm super new to this and had an iPhone for 5 years, but I think I download the new cwm so I can reset the counter, then do the emergency download with kies and I should be back to stock out of the box, right? I just hope I can find an easy guide to get the updated cwm, I'll search in.the morning. Thanks again for the kies suggestion.

So this "process" resets flash counter while installing factory image? Or would I need to use the reset file first? Please explain... And thanks.

I'm gona try this...just because...LOL
Thank you !!!.....g
P.S.
If you want to avoid the battery pull for the serial/model info, it's located on your original packaging if you have it....Just throwing that out..
I hate pulling batteries....g
Worked!
Thanks. Tried it for the hell of it and yes, you need to follow the OP instructions exactly but success if you do.
Thanks a lot. I've been looking for this, because event when i flash my note back to original rom, kies still didnt regconize the note.
:thumbup:
I can say with a Rogers note all I got was some asian text and an ok button
Worked perfectly! Thank you so much I just had to get cwm, reset the flash conter and let kies do all the work.
Thanks again~

Hi Agoat, I saw your sig you are on UCLE5 RC1, can you run touchwiz on this? i am running this rom from AppDroid too, but don't have touchwiz, can't run weather or add task widget to home screen. besides, this rom works perfectly smooth.
thanks
ever since i did this my phone keeps popping up communication error for looking for an update... is there a way to stop this from popping up????
Um, that's interesting because I've never run into this issue. Are you running the I717 on AT&T?? This has only been tested by me on the AT&T Branded US Galaxy Note.
It was confirmed by many (as seen on the thread) to work on the AT&T Note. Did you follow the directions completely? If you are able to get into download mode on the device, I'd say do it again and make sure you didn't end prematurely.

kies will not update firmware on rooted phone

Hi
I have rooted my SGS3 using the ALLINONE root from SGS3 Toolkit (http://forum.xda-developers.com/showthread.php?t=1703488) and it works fine. About a month ago I got a notice about a firmware update and I installed it using kies. The root ofcause dissappeared but I used the toolkit to re-root the device. No problem so far.
a few days ago I got a new notice about another firmware update and wanted to install it using kies. Now however kies tells me that the device does not support upgrading (something with "initialising").
What can I do to get this firmware update installed?

Flashing stock rom wipes your settings. Make a choice, either get root and forget about Samsung updates or flash stock and forget about XDA, can`t have it both
Moved to Q/A
I am not in it for the ROMs but merely for the rooting. In general I like the stock-rom as it is but do need to have the device rooted in order to use some apps.

Last time, once you have root you can no longer install OTA`s, you can however upgrade witk Kies provided you have no custom kernel. You will loose root and you may loose all your settings. So it will be easier for you to download the new rom from sammobile and install it with Mobile Odin Pro and keep root and loose no settings and files.
I have the same doubts/problems...
Where do I find in SamMobile the ROMs? Are those the zip under OTA files?
Do I the use Odin? Is there a guide somewhere? (I did search and ended up in this post)
Cheers
P.S. I read on SamMobile something about not being flashable via recovery (correct?)
See my signature item 3 or 4 about Odin

Based on my experience you can take an update via Kies or OTA with root as long as the stock rom remains intact (no major mods). I have generally upgraded with a stock kernel. I have mostly lost root or at least had to fix permissions each time.
The settings have remained intact each time (titanium should take care of this any way)

You can download OTA`s but you can not install it as you have a custom recovery.
You can upgrade with Kies but you`ll loose root and you have to reroot it.
If you install the updated rom with Mobile Odin Pro you`ll upgrade and keep root, that is what i`am trying to say

Cool ... I should have mentioned I have always had a stock recovery if sticking with stock Rom. Because as you say the updates don't work with non stock recovery

[Q] No update available after unroot

Good day,
I have a Samsung Galaxy S3 phone, which I recently unrooted. I followed this guide to unroot:
http://forum.xda-developers.com/showthread.php?t=1710613
I used Odin3, v1.85. The file I put in the PDA section was downloaded from the site in the guide and was the following: I9300XXALF5_I9300PROALF1_I9300XXLF5_HOME.tar.md5
I did run into some problems while attempting to unroot though, a few times I started the process in Odin to find it had failed after the first quarter of the bar was filled. I think this might have had something to do with my pc ejecting my phone whenever it felt like, but I'm not completely sure (the rooting was done on a different pc by someone else). Of course, because of that I couldn't properly start my phone and it gave me an error message about the firmware not being correctly installed. I persisted and eventually I got it working, though no idea how I managed.
Now, before the root and during the root I had Android 4.1.1, but after the unrooting it went to 4.0.4. Whenever I try to search for an update, either via WiFi, 3G or even Kies on the pc, it says there aren't any new updates. Device status is normal, and custom binary download is No. Bought my phone in Belgium, if that matters any.
Screenshot of the about screens in attachment. Is there anything I can do to get it to update, preferably without the use of Odin?
Please be gentle, I'm a complete noob when it comes to this and I'm not looking to reroot.
Thank you for reading through!
just connect your phone with computer and update via samsung kies
else, download the firmware from http://sammobile.com/firmware/ for your country and flash using pc odin

Thanks for taking the time to reply! I however already tried with Samsung Kies, and it says there isn't an update there too. I tried finding the latest firmware on the site you linked for unrooting, and it came up with the file I mentioned in the first post, which resulted in 4.0.4. I'm kinda hesitant to flash again, since I encountered problems when I unrooted.
EDIT: Just tried with Kies again, and it tells me it is the latest firmware. It says something like this:
PDA:LF5/PHONE:LF5/CSC:LF1 (PRO)
Root your phone again
And install mobile odin
Then wipe data and cache using Mobile Odin
It will factory reset
Then you will see that your device status becomes normal
Then go to super su settings and choose full unroot

Thank you! I will try that soon, when I have time. Just a question though, is there no need for Triangle Away with this method? I remember using it for the unroot before.
I think you should also use triangle away to reset the flash counters

Guess I'll post it here for people who happen upon the same problem.
Got it fixed, using this guide:
androidcritics.com/how-to-update-samsung-galaxy-s3-to-official-android-4-1-1-jelly-bean-xxdlib-firmware/
Basically just used Odin to flash the file downloaded there (I9300XXDLIB_I9300OXFDLI1_I9300XXDLIB_HOME.tar.md5) on the phone, worked after the second try. I think my problem is that my computer decides to eject my phone whenever it feels like.
After flashing 4.1.1, it found and installed 4.1.2 update, so I think it's fixed now.
Thanks to everyone who helped. Cheers!

I think I brick my phone, Please HELP!!!!

Hello,
I will mention every thing I did since Yesterday so that it can help you guys in helping me.
1) I used the following link to root my phone
The website doesnt allow me to post the link but the main site is called rootgalaxynote dot com
I was successfull
2) After the first step, I connected my phone to Kies and it said there is a upgrade version avaialble and I did upgrade it to 4.3.
3) Worked fine, but when I went to install Titanium Backup, it gave me a message saying that root access was denied and I need to root my device, smiliar message was given by SuperUser app.
4) So I followed the instructions from this thread and was able to successfully complete till Step 4 (A) in the following link
http://forum.xda-developers.com/showthread.php?t=1586223
After completion of step 4 (A), my phone rebooted itself and freezes at SAMSUNG screen.
Can someone please help me fixing this, If I need to post it thread somewhere else, please let me know.
Update:
I have done some search and found that clearing Cache might help. I have done that it still freezes at the samsung logo.
Thank
Nepo
PS: I can still however go to the CMW recovery screen.

May have been a corrupt file or something. I would boot into recovery and restore you nandroid backup assuming you made one and follow the directions again, this time without updating in Kies. Not really needed if your wanting to root to be able to flash roms etc..

Thanks Demmon,
I found a ATT Stock ROM on this website and was able to re-start my phone. How ever, I am having a hard time trying to update back my phone with the latest OS or even Jelly Bean and also the CWM recovery. Every thing is failing and crashing (Even the Odin give an error cannot find com/port)
I am not sure what to do.
Open kies and plug in device. Reinstall device drivers using the kies menu. Then Odin will work again.
You can also put device in download mode, open kies and select firmware upgrade and initialization. Type in model number in all caps. Then serial number. Let it do it's thing and you will be on 4.1.2 officially. Like a brand new phone without root. Odin will work again to flash recovery and roms.
