Hello all! Long-time prowler, 1st time poster.
Finally got my hands on a GS2. Very pleased with it. I've always been interested in custom roms and kernels, as I've spent dozens of hours researching how-to's and don't-do's, but I've been hesitant to take the plunge due to the risk and 1st-time unfamiliarity.
That is, until now. I was following the rooting instructions here: http://forum.xda-developers.com/showthread.php?t=1311081
Specifically, point 2c using Entropy's root method (phone had the OTA UCKK6 update) to revert back to UCKH7 2.3.4. Everything went as expected, root was achieved (2.3.4, kernel 2.6.35.7, superuser, etc.), but wifi is DOA. It appears that everything else is working fine, but when I attempt to turn on wifi, it starts scanning for a few seconds and then shuts itself off.
I've searched both XDA and Google on the topic, and while it seems to be a common occurrence, there is very little information in the way of solutions. The closest I've come to has been this thread: http://forum.xda-developers.com/showthread.php?t=1364039&highlight=wifi+broke
Appears that a full un-root is necessary? I just wanted to double-check that there isn't some silly little thing I'm missing or a more streamlined solution.
Again, noob here. Any advice or input is greatly appreciated. Looking forward to trying out some roms and kernels and learning more from the community!
I've got the same problem ... kinda...I followed the same steps to root, WiFi was fine after that, but when I flashed CWM-recovery, WiFi was borked. This is where I usually shhot myself in the foot ( as I appear to have done again). After more reading and research, I found that the ROM I was planning to flash (UnNamed) did its own kernel update so I figured that it may patch my WiFi problem.
Sadly it did not and now I have NO radio at all. (Cellular, data or WiFi). I get FC's from com.android.phone. (over and over... every 5-7 seconds.)
Hmmmmmm...
Flash stock again just to make sure it got everything

That had crossed my mind, so I went through the root flashing process again, Odin3 gave it a "PASS," but the problem remains.
OK... Should I wipe before flashing stock? Thats the one thing that I didn't do. I wasn't sure which wipe to do so I didn't. (oops???)
Do a wipe data/factory reset now and you should have wi-fi again. I had the same problem and it worked after I did the wipe data/factory reset.
ehhhhh.... somethings up here. I did a wipe/factory reset, then flashed back to my virgin ROM with CWM-recovery on board. My cellular/ data is back but WiFi is still borked.

Or did you mean that I should have did the wipe on the UnNamed ROM?
Trying to do a CWM backup through the Rom Manager App so I can do a data wipe/reset (through the factory-reset option, or through CWM, just to clarify?), but every time I try to make a backup CWM gives me this:
E: Failed to verify whole-file signature.
Any idea what would cause this?

It is posted prominently in several places in the I777 forums, do not use ROM Manager app.
Starting with UCKK6, then flashing UCKH7 plus root package is known to bork wifi. A wipe data/factory reset will clear it if you wish to stay on UCKH7. Doing OTA update to UCKK6 without a wipe also reportedly clears the wifi problem, and will retain root.
To use ClockworkMod Recovery, you must first install a CWM enabled kernel.
ya...

Yuppers... ROM manager is incompatable with the SGSII. I just learned that yesterday. Its a P.I.T.A.
You gotta delete it then flash the CWM-R kernel to get the nandroid backup. Yes you are now backing up a modded kernel but otherwise you are pulling a raw (and virgin) FS image.
@SeniorGato
I can't interpret from your post. If you restored a previous backup from ClockworkMod Recovery, then you probably reintroduced the wifi problem.
Anyway, you want to be on UnNamed. You should do a wipe data/factory reset before you flash UnNamed. Then for good measure, it couldn't hurt to do another one after.

I did in fact go back to CWM.
From the recovery screen of UnNamed, I kernel flashed back to CWM, then did the factory wipe, then flashed the backup I made. The WiFi did work when I was on that ROM prior to flashing UnNamed. Now... not so much.
Anyway... Off to look for that stock kernel, then start over.
So do a wipe before each flash then?
Just finished re-installing the OTA update back to UCKK6. Root is still good and the wifi seems to be working. Thank you Creepy and Gato for being so helpful and gracious. There's a huge amount of information on here that I'm trying to sift through and thus a bit of a learning curve, but thanks for helping me through the first hurdles!
Yes, you must wipe before changing from one rom to another, ie stock UCKK6 to UCKH7, or UCKH7 to UnNamed, etc.
You can usually get by without a wipe when flashing the same ROM, ie UnNamed 2.0.0 to 2.0.1
Hmmmm...
So I've wiped, flashed UnNamed then re-wiped. Now I have no modem at all (again).
Looking in the about phone I see some interesting things...
model number: SPH-D710
Baseband: unknown
Kernel version:
2.6.35.7-sph-d710.el13-cl806482
build number: UnNamed v2.0.1
hardware version : unknown
And strange behavior (aside from the no modem thing): when the screen turns off, I have to restart the phone all over again.
I downloaded the ROM through the developement forum under the I-777 so I THINK its the right one, but this descrepancy in the model number has me concerned. Is it normal for custom ROMs to display incorrect data like this or have I completely hosed this?
This is totally *not* normal.
SPH-D710 is Epic 4G Touch.
The kernel belongs to the epic.
It looks like the phone won't even recognise the sprint modem.
I'm surprised your phone will even boot.
Your phone is the AT&T Samsung Galaxy S II I777, right?
If so, you need to re-download the UnNamed install file. The latest version number is 2.2.1 (not 2.0.1) from here. The file you want is update-unnamed-v2.2.1-full.zip.
I don't have enough experience to tell you how to proceed, but here is what I think will work.
If the kernel currently on your phone has ClockworkMod Recovery, and if you can boot into recovery, you might try flashing UnNamed from there. Do a wipe first.
Or, flash back to stock plus root, install a CWM kernel, and then flash UnNamed.
Edit: Yes, gtg released an UnNamed for Epic 4G Touch, which is currently on version 2.0.1. Somehow, you have downloaded and flashed the wrong package, but knowing gtg, it almost certainly does not contain bootloaders or param.lfs, so you should be able to recover. The kernel contains CWM recovery based on 5.0.2.7, the same version we have in Entropy's DD kernel, so you might try flashing the correct UnNamed directly from that recovery. Since you could go SGS II --> Epic 4G, you should be able to go back the other way. If that doesn't work, then flash the stock plus root using Odin or the Odin One-click package.
Well that does explain...
Weird part is that I DID use the I-777 forum's download. Anyway, I'm redownloading now.
*fingers Crossed*
So this begs the question, how are the sprint galaxy s2 roms looking, and how hard would it be to build a 'hellraising' package for them? If a straight flash managed to boot, kernel and all, might open even more possibilities for us.

Siyah Kernel 2.6.6 Troubleshooting
Hello again!
I thought I'd give flashing a kernel a go. I've been following Creepy's guide to installing a kernel via Mobile Odin (bought the pro version; easier and helps out the devs!). Got it installed on the phone and put the zImage for Siyah in the internal SD-card root and flashed from there.
It rebooted and showed that CWM had successfully installed, but the kernel is still the 2.6.35.14 as it was before. Not only that, but wifi is also non-functional again. Tried to flash it again; same result. Cleared the cache/dalvik and also ran the kernel cleaning script, then gave it another go. Still no Siyah kernel, still no wifi.
Great start to my XDA career, I know. Any help would be awesome!
If you're sure you have root and can boot to CWMrecovery, you may try mounting the phones internal USB memory (not the removeable SD card) on your computer, move the entire zip into it and flash thru CWM recovery. Once I had the right ROM *sheepish grin* it worked immediately and perfectly. My wifi is back and everything!
A thousand thanks for all the help!
Edit: I just reread your post. First check what recovery you are booting to. 3e or CWM?

So here is one for ya.
I can't access my SD Card at all with this http://forum.xda-developers.com/showthread.php?p=25816870#post25816870 rom installed. I click to mount SD card and nothing happens. In recovery I can access the SD card backups etc
I find it strange. Although I do have to ask, I have been having this weird problem. I have Clean Rom 4.3 Installed (ICS) and I have been getting some random reset's and slow this or that. So I saw 4.5 was out - It literally reset everyime your open something and I mean anything Bam reset. However I installed the above rooted bleh bleh stock os (I do not have s-off so I used the PH img) I made sure I had no other boot images on there. Installed setup got everything ready. I have gotten 3 resets in 11 mins so far so now I backed up to Clean rom 4.3 and I have no idea what to do.
I also did the following:
Flashed back to STOCK o.s.
Then Downloaded the above linked rom, cleared data (everything) installed software patch and rom reset back up and same problem. I have been flasing rom's on this phone for a while now and this is the first time no matter what that I get these crashes and resets. Did I miss something?
You really should s-off that puppy. It is pretty easy, and will get you out of messes.

I assume you're always wiping data and cache.
Have to tried Fix Permissions? I don't know if this rom has it in it's settings, but using others I've corrected some weirdness by wiping the cache and then running fix permissions.
Were you seeing the same thing with the stock rom? Or just using clean rom? Might try a different rom for a bit to see if the issues follow you there.
S-OFF isn't going to help you with this. It's perfectly fine to flash your boot image outside of Aman-Ra. I do it all the time.
Are you wiping everything between flashes?
I recommend using this - http://forum.xda-developers.com/showthread.php?t=1562176&highlight=clean
Flash it first and it wipes the needed partitions clean.
If you're still on the GB firmware, you need to flash the old firmware patch after the rom install also to get SD card access.
If none of the above helps and you're still on the GB firmware, set the phone back to stock using the GB RUU, otherwise you will have to s-off it so you can do the same.
Yep full wipes between flashes. I didn't keep the stock Rom for more than about 20 mins.
I didn't see a way with the debloated stock New leak to fix permissions. But with the 4.5 clean Rom I did that and it made no difference.

Hey guys this is where I am with this issue. Kind of new to Android so forgive me if something is obvious and left out.
Bell Galaxy Note, unlocked via unlock code.
Please note that before I ever flash a new rom, I do a factory wipe, wipe cache, wipe dalvik..3 times first, then I redownload and install from Play
1. Noticed that my phone on Flappjaxx's rom was acting flaky. (ie FCs more than usual). This rom worked fine for a few weeks.
2. Tried CM9 via Rom Manager. Phone still a bit flakey.
3. Used CWM Recovery to return to FJ's rom which I made a backup first.
4. Phone even more flakey (ie. noticed some apps could get the internet, others could not. Phone would FC as well every time).
5. Tried clearing cache, dalvik, and fixed permissions. FJs rom still flakey (at this point 2-3 attempts to fully boot). Factory reset and caches cleared again but still the same.
6. Used Odin to flash the Bell stock system, recovery, and boot from this thread: http://forum.xda-developers.com/showthread.php?t=1599127
Did a factory reset using the stock recovery after this was flashed as well.
7. Having the same issues on the stock rom as I had on FJs rom and CM9.
8. I was eventually able to get the phone to allow me to see the baseband version before it rebooted (took a few tries) and I see the baseband is still UCLF6. I thought the baseband would have been reset too but I guess not.
Is there something else I should do? Will popping CWM recovery on there again and flashing another modem fix this?
How would that justify a warranty return? It's a result of you flashing custom software, warranty returns are for manufacturer defects. Are you restoring system apps or something in tibu? Otherwise just keep trying to get back completely stock and completely wipe everything.

This happens sometimes. You just have to find and flash the stock modem through odin to get it 100 percent out of the box.
As far as the warranty return, no one would allow it because you have no way of proving that the problems with the phone are not directly related to your modifications to the device even if they are not.
However, I would suggest flashing the stock modem and then reformatting your device through kies as a last resort. If this does not still work, I would suggest (although never used) the flash counter reset zip once youre on stock and sending it in for repair.
Hope you get it up and working

Understood about warranty of course.
- not restoring anything...as mentioned, everything is always set up from scratch, including all apps from Play store.
- I'm trying to get back to stock, and everything looks stock except that my baseband reads UCLF6, which I assume is not stock GB. I have tried flashing the modems, kernals, and roms found here http://forum.xda-developers.com/showthread.php?t=1506330 and here http://forum.xda-developers.com/showthread.php?t=1599127
This is why I am asking if my hardware seems defective, or if there is something amiss in what I am trying to do (if I am seeing UCLF6 in my baseband, I am assuming I am missing something).
Last attempt to get rid of the UCLF6 baseband I downloaded this modem: http://forum.xda-developers.com/showthread.php?t=1506330 , did a reset, wiped caches, and still showing UCLF6.
Don't know what I did differently, but I tried pterry30's modem and flashed via CWM (I could not find an Odin modem tar) and my phone seems normal now (but very stock) and I got the 'mugla' version of the modem listed in my system settings.
Thanks for the suggestions...hopefully its really fixed. Since I went through all this trouble I'll try Bell's ICS update.
Problems like this are great learning tools...but a bit stressful lol
Happy all is well. Good luck.
I have been having major problems with my i9100. The main symptom is that if shut down the fun in a violent way, i.e by taking the battery out or if it dies on me, then on restart it will just be stuck on the bootloader (the first i9100 screen) and won't boot. The only way i've found to fix this is by going into recovery and doing a factory reset, but this just keeps on happening.
i am using wanamlite rom LSD but this also happend with omega rom.
I tried to completely reset using odin, so i downloaded the odin image of JB but it wouldnt install, would take like 10 minutes and tell me it failed with no specific reason. So baisiaclly odin is off as well. i obviously also tried deleting chace delvik cache, reinstalling rom, installing different kernels (like siyah, it would even boot). nothing works! this is really frustrating, almost every day i need to completetly reinstall everything on my phone. Any ideas what is going on?
It seems that LS8 and LSD both have it. Try to flash LSJ or go back to ICS and wait for an official patch (fingers crossed).

Nuke script can get your device all cleaned up.

There is no bootloop or boot bug with JB roms. Its simply that people are not properley doing a clean install. A normal wipe data/factory reset is not enough in this case. Instead you need to format the /emmc and /sdcard or you can try the rom/kernel nuke scripts from dev forum.
Backup needed apps/appdata using TB pro or restore from a nandroid using appextractor.
