Hi, i'm currently new here, so i've been wondering how could I downgrade from (Unofficial) Android 4.0.3 ICS to Android 3.0 (or 3.2). I'm using Samsung Galaxy Tab 10.1. I used CM9 to get ICS.
I would be very thankful if anyone can help me with my issue.
Check this forum and the galaxy tab forum for any stock images that you could flash through CWM or equivalent for the tab - http://forum.xda-developers.com/forumdisplay.php?f=807 The Galaxy Tab QA also may be of help.
When I got back from ICS to GB on my SGS, I first flash a GB Kernel via CWM. Than i turned out my Phone and Reboot it into Recovery Mode, than i flashed the GB Rom on my SD Card. It worked really good. When I just flashed the rom without changing the Kernel, I got a bootloop.
Maybe I could help. I know, its a smartphone and not a tablet but I think the ways to flash are pretty similar.

i am also looking for a way to downgrade to gingerbread or even froyo if possible...my tab is samsung galaxy tab 2 p3110...plz mail me any information u have at [email protected]
Can anyone please help, I soft bricked my Samsung galaxy tab 7.7 p6800. I tried to install, cm10 custom rom, while i soft bricked my p6800 tab 7.7.
Now, i can enter download mode, and i can go recovery mode. When i switch off and switch on it automatically gets into recovery mode.
I could not do factory reset, through odin, i could flash, recover image, kernel, but not the rom, When i try flash any rom, it will try NAND rewrite, and try to factoryfs.mg and will get struck, nothing will happen, or i will get message failed.
I tried formating data folder, no use.
Is there anyway, can you please help me.
thanks a ton, in anticipation.

Sound like you got the SUPERBRICK. Had the same problem myself. This seems to have helped some people.. LOT to READ though. And NO guarantees as usually. Hope it will help you. READ carefully.

i think this may be A solution. here's the strange thing:
i thought i superbricked my tab--for 2 weeks now i've been trying to get it going again. i'd had some success with various roms, but then my cache partition corrupted. after trying to repartition data and system for a week, having to look for ever smaller partitions for both, i finally gave up, flashed the original pit file, and flashed the sammobile ICS ato firmware. i'm still stuck at the boot animation, BUT, MY CACHE SYSTEM AND DATA partitions are all checking clean with e2fsck, and some other contiguity checker i found in the gNote forums.
what they've suggested when all else fails if you're getting clean partitions, then flash back to GB (original firmware for the note) so i'm downloading stock HC firmware now and gonna give it a try... KEEPING MY FINGERS CROSSED!!!!

you shud reset the phone by entering in recovery menu.
This is why a Nandroid Backup is recommended prior to flashing anything. If you are getting bootloops it could be many things, I personally haven't owned a Sammy in a few years, but with HTC products if you are not running the right bootloader some ROMs won't boot (EX Sense based ICS ROMs require hboot 1.58). Restore your Nandroid and double check to see if you have the right bootloader/firmware running...hope this helps
*EDIT* I believe I found the right ROM (This post here?) It says its based on the latest firmware.
firmware XXKI3 Gingerbread 2.3.5

If you are on Sprint, you may be bootlooping because the ROM appears to be for the GSM variant, more details would help. If you are in fact on the GSM variant heres is a link with a GUIDE to help you flash the latest firmware
As the title says: P5110 keeps rebooting during boot - right after animation stops (before word SAMUNGS starts glowing).
Tablet is rooted and there is CWM 5.5.0.4 installed. Was just fine for almost half a year and all of a sudden this...
I have tried
- wipe data/factory reset
- wipe cache partition
- advanced : wipe Dalvik Cache (whatever that might be?)
I also tried all the "mounts and storage" options and noticed on thing: i can mount all storage mounts (/system, /cache, /data, /efs, /preload, /sdcard) but one - namely /emmc. Does it mean that emmc is broken? What is emmc? Is it important?
I am considering unrooting it and removing CWM. But not sure whether it's even possible and don't dare to try!
Can you tell me anything that might help me debrick this tablet?
Do you have nandroid backup(one that you make with cwm)? If yes go to backup and restore in cwm and hit restore....if not try to reflash rom via cwm or flash stock rom via odin in dowload mode.

Sorry to jump on this thread but might be a similar steps the OP has to take.
What if he flashes a new Rom and it still is locked in a strange boot up?
I posted a thread earlier today but either no one has an answer or my thread title was just crappy.
Mine did exactly what his is doing now (just boots the samsung logo and hangs) and now it just boots into recovery everytime you start it.
Flashing an original stock rom didnt fix it.
Flash via Odin any stock ROM then root it and flash whatever you like.
This kind of brick may occur easily if you have flashed uncompatible kernel or tried to restore nandroid backup of another ROM or made by uncompatible CWM recovery version.

Normally, it should actually work absolutely fine if you flash a stock ROM via Odin.
Nobody knows what did cause your problems and what did you flash as last. Also, different OS versions use sometimes different partitions. Even CWM recovery is not compatible through all versions, it uses different formatting.
So this way should work to restore stock ROM on your device:
find and download Odin that fits your device (earlier versions are not neccessarily worse ones)
find and download PIT file for your device
find stock ROM for your device consisting 3-files (for PDA, Phone, CSC).... ROMs are usually zipped, so you will get 3 data after extracting
The PIT file will do re-partitions for the case that your formerly installed ROM used different partitions whch are not compatible with the stock ROM.
After that you will have again unrooted stock ROM. So just be careful afterwards whatever you flash and before you do it, make sure that whatever you flash always fits your device (no matter is it whole ROM, kernel or just upgrade).

Thank you for the reply. I had posted a link in here that linked to my thread that explained what i had done and used but it didnt show up for some reason? Anyway I used the below roms(in bold). An update was available for JB and we own two tablets both the P5113 and bought at the same time. One tablet updated fine but the other one would download the package but then would keep failing to install it. So i did a factory reset on the device and then that's when the fun began and it started booting strange.
So I first tried flashing the official JB rom using ODin 3.04.
P5113UECLK7 (4.1.1) - Cellular south November 2012 (Official)
and it still did the same thing so then i tried flashing it back to ICS which is the rom that was on there i think. (It was ICS but not sure if that was the exact version number?)
P5113UEBLI1 (4.0.4) - Singapore September 2012 (Official)
Im sure the roms are going on there fine as if im not mistaken ICS has a blue battery charge icon and JB a gold one. I noticed that it went from blue to gold when i first loaded the 4.1.1 on there and then back to blue when i put ICS back on there.
I cant seem to find a PIT file for the P5113. Only for the P5100. Would that work?
I tried it anyway and it didnt work

If I was you, I wouldn't flash it before I am 100% sure it fits the p5113. I own the p5110 and they are indeed very similar, but who knows.... Take care of your Tab, mate.
BTW: why not CM10.1 stable? It works awesome, full wipe/factory reset, install zip through recovery, install recent gapps for CM10.1 (4.2.2) and after boot install Apex launcher and enjoy life

I hear you Its a paper weight right now though so thought id rather try as nothing else is doing the trick.
The tablets are my kids so i preferred to just give them an official stock version. I got put off using custom roms when i used paranoid android on my samsung galaxy 2 and it was real buggy. I just need my devices to work for the basics. I now run stock jelly bean on my GS2 but even that has crappy battery life, lucky for it to make it till 4pm and still be on and thats with moderate use. Couple of phone calls and a few text messages and a tiny bit or browsing. I know what is causing it though as it only starts to lose battery when im not on wi fi. It at least doesnt freeze and stop receiving phone calls altogether like PA did though. I used to miss a ton of work calls because the phone had actually frozen.
I love Apex though. I have Apex pro on my GS2 and its much better then the standard launcher. My daughter has the GS3 and it still does not rotate on the home and app screens which i find annoying.

I've got your point, mate. :good:
Same with me: I need all the functions to work. The CM10.1 does it really, but my p5110 is wifi-only device so I'm not sure if CM10.1 is same good for your p5113. CM10.2 seems to be smooth and fast, but many apps aren't yet updated for 4.3 so I will wait a while before I flash it again.
I have cm10.1 on my p5113...it runs amazing...the p5113 owners most of the time have to flash the p5110 version because there is nothing different with the tabs besides the ir port..

Can you reach the download mode? (press 2 buttons at same time: volume down and power button)
OK, yes- you need same Odin version as Tabs 51xx, this is link for Odin 3.07:
http://hotfile.com/dl/161620048/6c6d559/Odin3_v3.07.rar.html
Try pressing the buttons with the charger plugged in, as well as plugged out, that is little trick with the p51xx Tabs

Great, I am glad to hear it did charger cable trick help?
Just to make sure: you must be sure to flash a stock ROM first (not JB based custom ROM), after it you will have revived Tab without root. After that normal proceeding: root it, install CWM recovery or custom kernel that fits your ROM (or even whole custom ROM) which already features the CWM recovery.
The stock recovery (3e) checks the signature so of course you can't flash any custom zips. CWM recovery has an option "toggle signature verification" where one can disable signature check. Then you can flash whatever you want, just take care that all you ever flash must be absolutely compatible for your device.

One more thing mate, look at this video which I've posted on YouTube last January:
http://www.youtube.com/watch?v=0NXBN9Z63TY
It describes how to get rid of the signature verification problem. For the reason that quite many people don't understand english well, I have made a speechless video added by step by step description in the text (video description) so people can just copy the text and paste it into their translators.
If one ROM that you have flashed bootloops on the logo just try another ROM. It happens sometimes. Important is that you should always before flashing another ROM make full wipe: (data/factory reset/cache/dalvik) in your recovery mode.
Did you do it?
Please let me know if you were successful, it should work now! Good luck :fingers-crossed:
It works!
Thanks everyone for your feedback!!!
and my apologies for late response.
I followed the advise to (re)flash stock rom and it worked!
After that i rooted it again, installed another recovery and now have the latest stock rom working perfectly.
For those who get the same problem and the tabled keeps rebooting - just plug it into recharger and keep the on/off button until it turns off. Then you can fully charge it before you attempt to flash rom.
Once again, thanks a lot!
PS. now i am considering installing CM10.1

Great! Congratulations
Yes, install CM10.1.1 with gapps for 4.2.2 it works great, all the functions. Just mind that you can not restore nandroid backups made with other kernel, (sometimes also not if done with older CWM recovery version) and also apps backups made by Titanium backups in older systems aren't good idea to restore once you upgrade to CM10x
If you want to return for any reason to your old (current) ROM, do the same procedure like by unbricking
