[Q] Please Help: Roll-back from CM9 to stock w/Odin. - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Hello XDA!
I am having problems returning my Samsung Galaxy Tab 10.1 P7510 WiFi back to stock from CM9. I used Odin PC to flash the stock ROM. The operation completes successfully, and the tablet reboots, but never successfully boots past start-up. I have used this method with several other ROM's, and have never had this problem before. Can anyone please tell me if there are any additional steps I need to consider in order to roll back from Cyanogen Mod specifically.
Thank you in advance for all your help!

After installing the stock ROM, make sure you do a factory reset (wipe cache/data/dalvik).

[Q] Restoring TouchWIZ UI after Unbricking

Hi all,
I have recently aborted an attempt to load Tabuntu on my GT-7510. It took me some time to get the Tab to boot stably again. Even after flashing to the stock ROM, all programs kept crashing until I did a factory data wupe in CWM.
Anyway, that's not my problem. I finally have a working GT-7510 again
However, my Tab came from retail with TouchWIZ UI installed.
For my own reasons, I love TouchWIZ and I would really like to get my tab back to the way it was out of box. Is the only solution to use the custom TouchWIZ rom listed in the developers forum sticky, or is there a stock rom I am somehow missing, or am I misunderstanding my own problem completely? Please help! Thanks

[Q] Problem installing Darkys rom

Hello,
I have tried installing cyanogenmod. This worked, but I wasn't happy with it and tried to go back to darky's rom, by wiping to factory defaults, then wiping all data; and afterwards update to darky's rom.
But somehow, my phone isn't starting anymore. I also cannot go into Recovery mode. The only thing that is starting is Downloading mode. How can I get a decent rom installed again? :S
Pls help! I don't know what to do anymore
Can anyone help me out here?
Flash a stock rom and start from scratch
Hey, I never got it to work with cyanogenmod on my galaxy s, but since you dont tell which phone u are using its a little difficult. Take a look here, there should be a guide.

[Q]WiFi stuck on "Turning On" message

I have a problem with my 16GB Galaxy Tab 10.1 in that for some reason, while trying to pick up a WiFi signal from my Sky Broadband router (which none of my other WiFi devices has any problems picking up a signal from), the WiFi option seems to be stuck on the "Turning On" message and I don't know how to get it unstuck so that I can pick up a WiFi signal again from any device.
If anybody has any suggestions (I'm already looking at trading it in for a Asus Transformer Pad Infinity) to fix it, I'd be very grateful for them.
I had a similar problem. It occurred after using rom manager to install cwm on stock rooted rom and a factory reset fixed the problem for me, did you try it?

Sorry for the late reply.
I haven't tried it because I didn't know how to back up everything on my Galaxy Tab 10.1 to do so.
My problem occured weeks after I installed CWM on my Galaxy Tab 10.1
Also, does anybody else know if there's an alternate way to fix this problem without needing a factory reset?
Try to flash a different kernel. Odin or cwm doesn't matter. And you won't lose data!

Thanks for the advice! What's the best kernel to use as I don't have a custom ROM on my Tab 10.1 because all I did was just root it, nothing more.

But sorry to say it but I don't think you will avoid wipe data. I could be wrong but wiping fixes almost all problems...

I just hope I don't have to do a wipe as it would be a pain in the ass to have to do so (It's stuff like this plus the fact that I'm on my third Galaxy Tab 10.1 due to all the constant problems I've had with them that's making me switch to the Transformer Pad Infinity when it comes out!).
What's the best way of doing a kernel installation with this as I've never done one before? Also, how do I do a complete backup of the device?
I've installed the kernel via CWM after doing a wipe (and I did a backup in ROM Manager as well as via Titanium Backup AND backed up everything possible to my hard drive) and now my device is stuck on the Galaxy Tab 10.1 boot screen! (The one which says "Samsung GALAXY Tab 10.1" on it)
Does anybody have any suggestions on how to fix it?
UPDATE: I also can't switch it off using the Power button as well!
Did you flash the correct kernel? There are different kernels for ics and hc and they are different for every device as well. Get into recovery and wipe dalvik cache and cache.
Since you wiped the data, the best solution is still to go here:
http://www.sammobile.com/firmware/?page=3&t=3&o=1#osa.
Download your stock firmware, flash it via odin, root again and restore everything with titanium!

It looks like I used the ICS kernel for the 3G version (which is the version of the Galaxy Tab 10.1 that I have) instead of the HC version by mistake!
In the meantime, should I wait until the battery drains completely and try to recharge it to see if your advice works?
With the backup that I made with Titanium, I take it that's still safe on the device if I can get back into it?
You can flash without draining the tab. Also, everything in your /sdcard (music, videos, cwm backups, etc) don't get wiped. What you loose is only the apps you have installed. Just if you use odin flash only the Rom and not a pit file, as it will COMPLETELY wipe the tab, including sdcard.

I'm just downloading the firmware right now and I was wondering which option in the Files section on Odin do I use to flash the firmware. (Sorry for being such a noob, but it's been quite a while since I've used it to flash a ROM and I can't remember what the option was to do so)
In the meantime, thank you for answering my questions (I'm still going to get me a Asus Transformer Pad Infinity in any case) and showing patience to someone who's had nothing but problems with the device since he got his first one a few months back.
UPDATE: I drained the battery and recharged it, but from the looks of things it's still stuck on the same screen and still won't let me switch it off! It's a shame that I've been having so much with the Galaxy Tab 10.1 even though I've forgiven it for its lack of microSD slot.
Hey no prob. That's the best way I can contribute here for the moment. I am glad that my advices are somewhat useful to you.
Here is a complete guide to restock the tab:
http://www.teamovercome.net/p7500/?page_id=5
You don't have to use the provided stock rom, since you are downloading your own! Just skip the pit part, unless you have backed up everything in your hard drive. I don't know the exact options, since I have never used odin for the tab, but it explains it all with screenshots.
I have a small favor to ask. Can you check whether the binary counter will increase after that? In theory it shouldn't be affected, because you flash a stock rom but I would be grateful if you could tell me what happens.
Yeah, the only thing which bothers me too is the lack of the microsd but ok, I decided I can live with that!

The device is still stuck on the screen with the Galaxy Tab logo on it and won't switch off at all! Does that mean it's unfixable or is it one of those boot loop problems that I've read about here?
I'm seriously looking at sending it off for repair or replacement if it can't be fixed.
This happened after odin? Just wait a little bit. It usually takes a while for the first boot.

I haven't used it with Odin yet. Should I wait for it to drain fully and recharge fully before trying again?
Also, it's good to know that my data is safe and all I need to do is to root it again and reinstall my apps using Titanium Backup.
It's best to be full before you flash. If the battery is drained before the process is finished then you have a brick!! Just please check your binary counter before and after you flash the stock firmware. I really need to know this... You can see this number in the downloading mode screen. Your tab will be fine...good luck!

I've fully charged it up to 100% so hopefully it should be safe to try and fix the problem.
Also, I've downloaded what seems to be the latest Vodafone UK stock ROM and I take it that's the one I should be definitely using to return the device to stock?
Yes, that is correct, although it does't matter which rom you choose as long as it is for p7500. I am waiting for an update with good news!
Sent from my amazing 10.1 galaxy tab
Sorry I haven't updated in a while, been kept busy.
I've plugged it into the laptop after charging it up to 100% but it's not being recognised by the laptop at all even after reinstalling the USB drivers.
I've managed to get into the screen with the Android Downloading icon on the right and the folder logo on the left. What should I do next?

[Q] My Samsung GT-S5360 stop working!

Guys, please help. I've messed up my phone (Samsung Galaxy Y, GT-S5360) after installing the Kernel update, the merruk clockwork mod recovery, the ext4-converter without backing up my stock kernel. I just read that I need to backup my rom but I've already done the instructions. How can I retrieve my stock rom and have my phone working again because right now it isn't working. It opens but it keeps on freezing everytime I opened it, I hope someone can help me. Thank you.

First of all, where does the phone freeze? After android loads, or during the boot process?

Help!! Galaxy Tab S3 stuck in bootloop. Needs reflash with CSC t820xxu2brl2

Hi All,
Noob here. I've reflashed older Galaxy devices to LineageOS with no issues, but I'm worried I've bricked my Galaxy Tab S3. I flashed TWRP no problem, flashed Lineage OS and Gapps and rebooted, but it got stuck on the LOS boot screen. I thought I'd re flash the original firmware, but it lists the target as t820xxu2brl2. Looks like the CSC code to me, and this doesn't seem to exist at all to download anywhere. I'd like to install LOS, but would happily revert to stock just so I can use the thing again!
I don't know if:
I have to re flash the stock firmware
or
I'm missing something that will help LOS boot loop issue.
If anyone has any ideas, I would be grateful. I've alread lost 3 days of my life trying to sort this!!
Thanks!!

Reflash LOS. Maybe you have to do a factory reset. If you have a backup of all your data.
Flashing back any recent stock firmware for your device and region should work fine too.
