Help

I am trying to root my Samsung Galaxy SII Skyrocket on which I just installed the official ICS from ATT/Samsung. When I try to install CWM using Odin 1.85 it fails. The Message box says "Can't open the serial (COM) port. All threads completed. (succeed 0 / failed 1).

Can anyone help me to get this phone rooted.

Thanx!!!

I'm trying to root

When I go to "choose zip form external sdcard" it takes me to the internal directory. It looks like I cant get to the external sdcard form CWM

How can I fix this?

Can I root by placing the SuperSU-0.93-Busybox-1.20.2.zip file into the internal sdcard?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] vincom:
you can put the file into internal, or in cwm goto mounts\and click mount sdcard which makes the ext sdard visible

WooHoo!!!!

vincon=outstanding

I did what you said and read all that I could on rooting my i927R..... then I read a bit more. Your directions are a concise and thorough. From start to finish, it took me 7 minutes (and I've got oldguy syndrome). You have empowered me!! Thanks so much, vincon. Thanks also to all of the n00bs and experienced forum members for asking questions and helping with advice.

BTW... one small, small addition which may avoid the same moron error which I made...... during the "root" procedure, tell the n00bs to put the SDcard into the device. :o I didn't do that because it wasn't in the directions. :confused:

Now, I'm rooted. I've been trying to figure out what rom to use. Is Jellybean worth it or should I go to ICS? I was looking to see if vincon had a preference but didn't see a preference in his posts.

Any help is appreciated.

- I have spent weeks reading this and other posts. This is THE best!

- Installed CWM 5.5.0.4 per your guide.

- Used your method to install ICS as kies would not load on my notebook.

- After I root using your foolproof method I want to install Cyanogenmod 9 RC2 but cannot find concise instructions. Also I have read elsewhere that CWM 5.5.0.4 will cause a loop if used to install CM9 and I should use CWM 5.8.1.3

Can you link me or give me foolproof instructions for CM9?

This is obviously my first post and I hope that the thank you button will appear so that I can thank you properly.

Many thanks for you step by step clear instructions.

Thank you!!!

Just wanted to say thank you for this guide! I have used it several times to root from GB and now ICS. I read everything I can even when I don't fully understand what I am reading which usually puts me in the category of knowing just enough to be really dangerous. I have never had any issues when following your instructions, granted I print them and reread them at least 10 times while going through the steps. Thank you again for all the time you have put into making this one of the most valuable threads out there!:)

1. which odin are u using, should be 1.85, redownload again

2. redownload the firmware tar again and flash again, if both of these steps fail then

3. flash a custom recovery w/odin(follow instructions on 3rd link in my sig) then flash a cwm flashable stock firmware, link are in the dl section in op

if all that fails then it sounds like you have a corrupted efs partition the same as this http://xdaforums.com/showthread.php?t=1751338

possible fix Using loop devices to workaround corrupt eMMC partitions

if still under warranty get it fixed

What is the most recommended custom recovery? I'm interested in twrp2 but I'm not sure if I should use cwm touch instead(is it more stable?)

The method of flashing twrp2 is the same as other recoveries? (twrp thread didn't have any instructions, just release notes)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] vincom:
twrp is stable and cool

are you on stock or custom

stock you need to odin twrp tar file

if already on custom recovery flash the twrp zip file

all files are in the first link in my sig under recoveries
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] dewaski:
I'm on stock right now(sig). Are the steps pretty much the same for twrp? One thing I'm not clear on is actually how to get the tar file for twrp. Do I have to use goomanager to get it? I read that you already need to be rooted to use it so I guess in this case I need to install cwm first?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] vincom:
you can use the link in this op or the first link in my sig for the twrp tar file and its the same method to flashing cwm w/odin just use the twrp file, but dont change the name of the file which is "recovery.tar.md5" and use chrome to dl it

Hi,

I tried the steps given to root my samsung s2 sgh-i727r on rogers but something doesn't seem right.

I have attached a picture of what it shows and it is definitely different from the pics shown on page 1 in instructions. Can you tell me whether I am doing something wrong ?

Thanks

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] vincom:
your phone is not in download mode, repeat the steps in getting the phone into download mode, rogers phone just hold the volume down button in step 7.d, if that fails go through the odin troubleshooting section
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] dewaski:
Another question about TWRP, it has the option to backup "recovery" as well for a nandroid. This basically backs up the current state of TWRP with everything else so that when you do restore, you'll have your backed up system + backed up recovery from the previous state it was in (so you don't have to flash custom recovery again)?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] vincom:
ive seen that option but i have never enabled it, as far as i know ive never seen any1 else try it either, but u could be the 1st, but it would only work if you were on twrp recovery in the first place, so its pointless on backing it up
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] dewaski:
I used twrp as my first ever custom recovery so maybe it isn't pointless for me :p

But let's say I did a nandroid without backing up "recovery", once I restore the system, do I have to flash twrp with odin again?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] vincom:
no, twrp will still be there, the recovery is not part of the system partition, so if you restore the backup whatever recovery you had b4 will still b there, no custom rom wipes or installs the recovery partition

cwm does not backup or wipe the recovery partition

flashing stock firmware through odin will wipe the recovery and install the stock recovery

flashing a flashable stock recovery which some devs have made using a custom recovery might or might not flash the stock recovery depending if they left the stock recovery in the flashable stock firmware

Google Chrome

I don't do Google Chrome. Damn.....the very first page says to only use it to download files. Is this a must?

( I have to admit I'm not a google fan) So what am I doing messing with Android you might ask? Well if you're curious and it matters, it's because Android is based on Linux, which is open sourced.

Not trying to start a flame war here, I just don't want to be trapped into doing things Google's way (or anyone other huge company's way), if I can help it. That isn't remarkable in and of itself, after all, isn't that what this topic (and XDA when you get right down to it), is really all about?

So....if I haven't disqualified myself from obtaining help, is it imperative to use Chrome?

I don't know what I'm going to do about the Market yet. I'm hoping the few things I need can be side-loaded I guess.

Chrome...

Just download them on your computer and transfer via USB. Same thing... Also, you don't even have to run your phone as a Google app phone. Just don't install the gapps... It does change a lot of how the phone operates and the ability to restore things like contacts, google music, etc...

OR

Goto the "OTHER" Linux based phone... Good luck with that.

okay so now its been 2 days or so and I am starting to lose it. My phone wasn't being detected properly and there were some driver issues. Tried installing kies but it won't connect. After doing some other stuff and changing settings here and there my phone wasn't even recognized as a usb storage for sometime but I managed to fix that somehow. Seems like I am going deeper into this ****.

Finally the odin thing could recognize my phone and I did the steps as given on page 1 but unfortunately the final result was a Fail. I just want to get this thing unlocked and I am not even able to root it. Any comments on what might be wrong ? I am new to android and smartphones.

its detailed and explicit because newbs would not get it, communicating w/them led to the rewrites which is what you see now

when i was using ie 8 and ie9 it would not dl an md5 extension properly(sometimes), chrome did it correctly all the time, thats why i mention it, never tried it on firefox but should be the same as chrome, but it was easier to tell newbs to just dl chrome since its lite to dl and install then to get into a long explanation as to why.

Rogers SGH-i727r

Hi,

I'm not sure if this is addressed or not, but i did a search and found no resolution to my issue. I rooted and installed the stable version of Cyanogenmod 9 for my Rogers SGH-i727r yesterday, and have some questions after the successful install.

First question, I'm not getting LTE service on the phone, I had LTE when i was running the official ICS firmware from Rogers. I've added the LTE APN settings but it doesn't connect, it'll automatically choose the rogers-core-appl1.apn APN settings. I know that the LTE indicator should be 4G, and H = 4G, etc, but at times, i don't have an indicator at all.

I also went to *#*#4636#*#* and selected LTE/GSM auto (PRL) and I have baseband I727RUXLF3

Second question, how do i restore all the apps that i downloaded/installed/paid for without downloading them again?

Your help is greatly appreciated.

Thanks!

You sir need to read and search.

To answer your questions, You have to reroot. As for if you did it right on gb, well were you able to give apps su permission? If so then yes. Root stays unless you upgrade to an official stock rom in which case you need to reroot. These are the BASICS. I suggest you go over the guide thoroughly a couple times.

You need to learn how to walk before you can run.
