[Q] Switching to stock gingerbread from ICS - Galaxy S II Q&A, Help & Troubleshooting

Alright, so I went into the phone store to get data for my phone, but the person told me that since i upgraded to ICS, the phone is not going to be recognized etc. that was some time ago and I don't remember what he said entirely. He suggested I go back to the stock gingerbread that my phone came with, but looking around I can't exactly seem to find it. So going through androidfirmwares.net i downloaded and flashed one that looked promising, (JPKJ2), but after rebooting my data was not appearing. I guess my question is where can i find or do to restore my phone to the stock gingerbread that it came with? It's international and unlocked.

Intall the Titanium Backup Pro, backup your phone. Then flash the stock GB, install the CWM Recovery. Thru the recovery do a restore. That's it.

Yeah, that's the thing. I can't find the stock gingerbread to download. Also, the person told me once I went back to GB the data marker should appear, which it did not :/

[Q] Flight mode won't turn off!! HELP!!

Hey, what's up. So, here's the problem.
1. I flashed Void, I didn't like.
2. I flashed the stock rom (froyo 2.2).
3. now airplane mode in "settings > wireless and network settings" won't turn off.
I've tried taking the battery out for 10 seconds and putting it back again to no avail.
Help please!!!! Now I can't make any calls or anything cuz I've got no connection anywhere!!
Reflash the stock ROM
Sent from my LG-P500 using XDA Premium App running miks CM7, quadrant 2100, over clocked at 787
wipe all. try to flash devoid its 2.2 but a lot better.
How did you flash stock ROM? By creating a KDZip(stockrom.zip) and then flashing it? Anyway try to wipe dalvik-cache via Recovery.
1. I've flashed the stock twice
2. I don't wanna go for another ROM at this stage. Getting an error when restoring, and not being able to restore, a nandroid backup is what landed me in this mess, and I'm not sure what other misleading information about Romming I've been fed.
3. Nah, I flashed the stock .DZ.
4. Would my service provider be able to format and reinstall android, or will I be looking at getting a new phone?? Cuz that would suck.

Well, if you keep restoring messed-up/corrupt/broken settings etc., no wonder flashing does not help. Wipe everything and flash a stock ROM, do not restore any broken mess. That is what your provider would do anyway, so no need to waste money.

I did flash shiny ROMs located on this forum over here. I spoke to LG and I have to call them back in a couple. They're gonna get the same phone and we're gonna walk the problem together.
Like 20 minutes or something later..
Yeah, so they said they don't know and I should take it to an MTN outlet. They're not very helpful on Sundays I think.. Gonna take it in tomorrow then
Oh yeah, and i would still like to know..
..if my service provider would be able to restore original Froyo 2.2.0 or if I should consider forking out for a new phone?? .. Or if by any chance LG could restore Froyo bearing in mind that I've flashed 2.2.1 stock and the phone has been un-rooted, or if they'll say hard luck??
Well, as I already said. You still have lingering junk there. Flight mode is not some miracle, it is simply a profile with WiFi/BT/2G+3G turned off. (What can be turned on in flight mode is set in an sqlite DB, so it is even possible to override it).
So, no matter what you have flashed or not, you did that incorrectly. Being unable to switch flight mode on/off does not come out of nowhere.
There is absolutely no need to buy a new phone, your problem is a software one, not a faulty HW. (For questions what LG will or will not do, ask them, not here.)

Thanks ^_^ You obviously know more about this than me, so how do you suggest I proceed if I wish to get back to stock Froyo like it was when I got the phone?? Should I take the phone in to service provider or something??

Well, if you are unable to restore the original ROM properly, then take it somewhere where they can. Does not necessarily have to be your service provider, any authorized LG service can do that, plus lots of unauthorized shops can do it as well (warranty is a different issue here, though.)
Anyway, before you take the phone somewhere - if you flashed something from the thread you mentioned, you probably have 2.2.0 or 2.2.1. Have you tried using LG PC Suite to upgrade the phone to latest version (should be 2.2.2 pretty much regardless the operator/country). Might get you proper flash as well.
Also, CWM recovery has Wipe All option which wipes everything except for recovery.
Thanks so much ^_^ I got a 2.2.1 *.DZ. I don't have the energy to struggle with that anymore so I it took to my service provider and the guy there ordered me a new phone. Awesome of him hey!! At the end of the day, phones were actually made to call, TXT, and tweet with, so I'm through flashing. Time for me to throw in the towel and show it some love just the way it is!!

Oh yeah, and I tried upgrading to 2.2.2.. No luck, it said I had the latest version already at 2.2.1. Doesn't make any sense right. And that's from the official LG updater thinggy.. Hey, how do I mark this thread as SOLVED??

[Q] Factory reset not resetting everything?

I'm fairly new to the whole rooting business, and got my phone rooted the first day I had it and customized it how I wanted. Now I want to wipe it to try some new stuff. I've already backed everyone up with Titanium Backup and made a Nandroid recovery, but when I performed a factory reset/data wipe, I reset my phone and it still loaded my rom (the dasBAMF 3.0). Since I wiped but my Rom loaded (my assumption at least) something isn't working correctly and my keyboard won't pop up when I need to type in text for anything. Did I miss a step to completely wipe my phone...?
EDIT***
Really, I just want to try and get my phone either back to stock, or as close as I can (since I don't know what they check for when trying to exchange at the verizon store, if possible) so that my warranty is voided and stuff....
Yeah... You missed the who step of flashing another ROM. It's going revert back to the last ROM that was there if it isn't replaced.
Oh :/ Where would the vanilla TB rom be? Cause I might just be missing it, but I can't seem to find it in Android Development.
I would prefer to exchange it for another phone, so I'm trying to get it back to stock (or as close to it as I can if all they do is look at it without checking so I can exchange).
You're gonna want what's called an RUU. I'm not sure where the most recent OTA RUU is or who's been taking care of those. It should be in the dev forum. The version number should start with 1.70. To flash it, change the name to pg51img.zip and flash it like you would a radio. It will snap your phone right back to factory stock. If you can't find it, let me know and I'll try to hunt it down.
There's this:
http://forum.xda-developers.com/showthread.php?t=997724&highlight=RUU
but none of the file names start with 1.7? Also, the TS has in caps red: "DO NOT FLASH THESE OVER ROOTED DEVICES, UNLESS YOU KNOW WHAT YOU ARE DOING." and I wouldn't know what to do with it even if I got the RUU that started with 1.7.
EDIT***
Well, I found this:

Since I'm new, that will work for me too, correct? I see nothing stating that it shouldn't...

That last link, got to restore to stock for root and non-root users... That will work. Basically, after you flash the first one you'll be stock without root. The second flash will restore S-on.

Can't update stock rom, "Communication Failed" from Software Update

I'm not sure if I'm the only one who is having this problem but I've searched around and can't fix the issue. I recently had CM9 but went back to complete stock, on 2.3.4 (which isn't up to date). When I go to update from the settings menu, I get a communication failed text box, which then in turn makes me wait 24 hours before checking again.
I've done multiple battery pulls and stopped the running process for the software update to no avail. Can anyone help me with this?
Remember, I'm on the stock AT&T rom.

I think others were having trouble updating as well... I'd suggest flashing a custom rom, or if you want to stay with stock, using Entropy's Back to Stock packages (I'm not going to link that for you cause I'm too lazy and you should be able to find it.)

Might give it a try. Trouble is, not having a rooted phone and going back to stock means I lose all applications and data with them. Eh. Thanks
Download stock rom (if u can get a tar file it most likely has everything u need, do some Googling just make sure its for the i777). Get mobile odin pro. Use mobile odin pro to flash the .tar and it gives u the option to root right there within the app before u flash. Profit. Just giving my two cents and what worked for me . If u do this though and don't remove any system apps it should allow u to ota upgrade. Haven't tried myself but that sounds like it'd work fine.

I already did this except for rooting about 3 weeks ago. From what you're saying, if I root my phone from its current state I should be able to receive OTA updates? I'm willing to root just to see but I don't see how that would fix the "communication failed" errors for updates.

FYI I have a rooted stock ROM, and I'm having difficulty doing an OTA update also. Different error (mine is "interrupted" after reboot). I posted it here because it seemed more related to that thread and I had other Q's about the process.
You guys are in panic mode, wait till we actually get an ANNOUNCEMENT for ICS from AT&T, then try to go back to stock using the methods we have.
No reason to do so right now, since AT&T will probably take a long time before pushing it.
We have a possible sources dropping on March 15th from i9100 but you will be required to be rooted to flash the possible ICS Roms that will be available after that date.

I don't think you understand. First of all, in no way am I in panic mode. Secondly, my phone is a few updates behind since I just recently brought it back to stock from CM7. All I am trying to do is bring it up to date.

You might want to check the (Guide)How to flash custom binaries.....on this forum. Creepycrawly has posted a reply towards the end of the thread that might be helpful. Believe its on one of the last two pages.
As has been said many times in other threads, even on a stock ROM if you have rooted and removed even one item of bloatware or made any other mods you will not be able to download an OTA update.
I have not rooted my phone. And as I said earlier, I restored my phone to complete stock meaning no bloatware has been removed. I'm still at a loss for what to do

You were on CM9 (in a later post you say CM7), but you went back to stock UCKH7. Now you are unable to update over the air to UCKK6. You are mainly interested in having the phone ready to receive the update over the air to ICS, whenever that occurs. You have not rooted the phone since you returned to stock but you are willing to try root if it will help the update happen. You were also concerned about loosing apps and their data since you are not rooted. I recapped all this because on stock you should be able to run the update. To help you solve the problem, need to know all the facts.
I've done the following, although it has been several months ago, about a week or two after UCKK6 first released. From running a custom rom, I did a wipe data/factory reset, flashed stock UCKH7 plus root, and ran the over the air update to UCKK6 successfully, retaining root on UCKK6. I just did this to test it out, so after completing the test, I used my nandroid backup to return to the custom rom I was on.
I would assume that you did a wipe data/factory reset either before or after you flashed back to stock? If not, there could be traces left over that could interfere with the update process. I'm not sure if there could be traces left even after a wipe data/factory reset, but the Cyanogen Mod file structure is so very different than stock that it wouldn't be inconceivable.
Next, I would wonder how soon after flashing back to stock you tried to run the update, and if not immediately, what action could have possibly placed or removed files that would intefere with the process.
I'm pretty certain that if you were to wipe data/factory reset with a format and then flash stock again, and then try to run the update immediately, it would succeed. So there has to be something in the file system preventing it. You may not find it easy to correct that something manually. You may just have to do a wipe data/factory reset, and maybe a format, and then start all over with a fresh install.
Of course, that is the reason for rooting first. Root, then back up everything with titanium backup, SMS backup, export contacts, etc. and save all that to your computer. Then you can restore stuff after.
Thanks creepy,
I'm in the process of doing what you said. I rooted my phone, backed up everything I thought needs to be backed up and flashed the stock rom (2.3.4 kernel version 2.6.35.7 baseband version I777UCKH7). I still need to do a factory format in order to see if that will fix the update problem.
Question. Is the firmware version(s) above the latest AT&T software? According to Kies, it is. But I am reading other places that the latest software is android 2.3.6.
Did exactly as creepy stated. Brought the phone back to stock software and did a factory reset. Without ANY customization and as soon as the phone booted up, I did the software update and had the same thing, "Communication failed" (says there is an update available but servers are busy).
I give up.
Well, I don't have any new ideas. Maybe if I get some time in the next few days I'll try it on my phone to see what happens. It has been a while since I tried it. Maybe the server behaves differently now?

From what I've been reading on AT&T forums (http://forums.att.com/t5/Samsung/Sa...2-3-6-OTA-update-now-live/td-p/2996495/page/3) I don't think so. I've been trying every combination I can think of to make this thing work but I honestly have no idea. I was extremely surprised when I brought the phone back to complete stock and no root and still couldn't get the update.
If ICS ever comes to AT&T GS2, I'll wait a month or so to keep trying then I might resort to going to an AT&T store to get a replacement. Who knows

Help i messed something up

ok so i wouldnt say im a noob but im not as advanced as some of yous. last night i flashed a leaked ics onto my phone and loved it with one exception. i couldnt figure out how to root it. all my apps are backed up on titanium backup and i didnt want to have to get all of them manually. so i flashed back to stock using odin with a file i used back when that crappy update came out. i rooted it with super one click and and then went to put on a prerooted ics... when in recovery mode now i get this message
cant access to '/system/csc/att/system/'
i try putting on cwm and siyah and i keep getting authentication errors and the installation aborts. also recovery mode wont read my external sd card now. when the phone is booted up it works fine except i tried to do the factory ota update and it keeps failing. i tried reflashing back to stock again and did the update unrooted and it still failed.
i know you guys hate hate when people ask without researching so i did SOME forum browsing and found nothing. sorry i dont really have time to look too extensively. i just want to know how to fix it. i appreciate any help i can get

Start with getting back to stock using this guide. Check for ICS bootloaders too, you probably flashed them and you have to get stock ones back (careful, flashing bootloaders can cause hardbricking). Once you're back to stock and rooted, you shouldn't need to ever use PC Odin again.
Then use this guide for rooting/flashing.
One other note: when you tried to install CWM, it sounds like you loaded an update.zip onto your phone then tried to install it using stock recovery. Stock recovery won't let you install unsigned update.zips, which is why that method for getting CWM on your phone will never work (hence the authentication error and installation abort). For our phone, CWM is only included in custom kernels, that's the only way to get it on there, and don't even think about updating or changing it via other means. Just flash a custom kernel, it'll include CWM, use it until you want to switch kernels.
Hit my thanks button, I was really nice this time. And post in Q/A next time as well.
EDIT: Skip the second guide if all you want is stock. You should be able to update OTA after following the first guide. Though even if stock is what you want, I highly recommend flashing a custom GB kernel because a) they're more stable and faster and b) you'll have CWM in case you need it.
You started off mentioning about "leak ics" which I have absolutely zero experience.
My suggestion:
1. Try to get it back to stock. Make sure it works correctly.
2. If hasn't rooted yet, do so.
3. Getting CMW into the device by flashing custom kernel.
4. From there, install any ICS ROM you want.

Going from ICS to GB?

I have tried on countless occasions to go from SlimICS to Cyan7.2, but everytime I do I soft-brick my phone :/
What do I have to do? Do I have flash some sort of GB Kernal beforehand? Link?
Thanks.
When you bought your phone did it had ICS pre installed ? If yes then u will never be able to use GB
It did, BUT.
I got it second hand, and it came with SlimICS.
The person I got it off quite it very soon after it came out - so I believe that it would have originally come with 2.3
I don't think what was said above was accurate anyways.
Try flashing a Samsung stock Gingerbread firmware (any, probably won't matter which one, as long as it is for your model phone) via download mode (using Odin or Heimdall) before attempting to flash CyanogenMod 7.2.
