I have a bootloop problem with my Samsung Galaxy tab 7.0 GT-P6200.
I want to recover my datas (photo and stuff from last back up)
I read post from others with similar problem, but it's not clear for me what to do.
If you have a simple way to do it, please, let me know!
For the moment I can access to download mode and to recovery mode.
I did not know nothing about nothing, so I tried:
in download mode: the option to download a costum OS, but I was stuck to "downloading, Do not turn off the target." ...At this time, did not know that I should I plug it to a computer and flash a firmware.. So after a while, I juste turn it off...
In recovery mode, I tried : "reboot system now" (doesn't work) and "wipe cache partition" (nothing new).
My two other options in this mode are : "apply update from external storage"?
and "wipe data/factory restet"
Should I do a factory reset/data wipe?
Some say than doing this, you loose everything. I would like to recover stuff.
But... If I understand well, others seem to insinuate you keep your personal datas : https://forum.xda-developers.com/showthread.php?t=2583588
So does "wipe data/factory reset" really is safe for my personal datas?
On the other hand, at the end of this post: https://forum.xda-developers.com/showthread.php?t=3115333
like a ultimate issue, it's recommend to flash stock firmware "you can flash official firmware (from sammobile.com) with Odin, remeber do not select "re-partition" and "PIT" option, after flash u can ran your TAB and seve all data."
"All your data will be safe, odin flash only system data files."
Flashing a stock firmware really will not wipe my data?
if not, I read, I should be able to do it, but... I have a other problem, my original firmware is not available : honeycomb 3.2 spain. I wrote to sammobile, I will see if they can find it for me?! But if you can help, it would be appreciate!
any way is welcome!

I am selling my 3g xoom rooted and rom'd with EOS 2.0. I need to wipe my data and keep the rom. I think I do this in cwm? Please advise.
1. take out your flash drive
2. delete all your userdata under /mnt/sdcard
3. press power button, select Reboot -> Recovery
device now reboots in recovery mode
4. select wipe data/factory reset
thats all.
I didn't get this msg in time. I ended up rerooting and that finally worked. However, when I tried to just use the wipe data/factory reseting cwm, I received the following error msgs. Posse see attatched photo. I sure would like to know what it means.
The Wifi on my phone wasn't turning on, even after factory reset, so I reflashed stock ROM via Odin (v3.07)
I got stuck in a bootloop, and after factory reset via the stock recovery + wipe of cache partition, it was still stuck.
I then re-flashed the stock ROM. Still stuck.
Tried using Kies 3, with the firmware upgrade and installation tab. Said something about not supporting my phone when I was prompted to plug it in. (SM-G355H; Samsung Galaxy Core II Duos)
I then found an unofficial version of CWM v6 for my phone (there's no official support), and quickly flashed that (via Odin 3.09; which is what I use from this point on), forgetting that my phone was no longer rooted. I wiped davlik cache and data. Still stuck. Then I rooted my phone. Stuck.
Then I reflashed stock ROM (this time, I downloaded from another website) (to test my luck, I tried seeing if simply a factory reset and cache wipe would work. It did not) rooted my phone, and flashed CWM. Wiped davlik cache. Still stuck.
By the way, when I wipe davlik cache it says:
Warning: no file_contexts
E:unknown volume for path [/sd-ext]
Davlik Cache wiped.
Any ideas on what to do now? I can't send it to a manufacturer / repair store where I live. I'm thinking maybe I should untick Auto Reboot and/or F. Reset Time when flashing, use an earlier version of Odin or the ROM itself, or maybe there is something I can do with ADB? I'm not very familiar with it, but I'm more than willing to learn. I just need some direction...
Update: Flashed with Auto Reboot unticked. Still in bootloop.
Flashed with same ROM, different country. Still in bootloop.
Alright, I fixed it by using Kies, via firmware upgrade and installation. You have to ignore where it says that your device is not supported, and just leave it to download. If you get stuck on the setup screen like I did, try cache wipe + factory reset. If it doesn't work flash an earlier version of the firmware. You might be using the wrong region (It's not always your country), use Kies to check. When it tells you what pda/ modem / csc it wants to update the region will be in parentheses ( eg ACR). Use all of them possible
Hello. A year ago I bought an unlocked SGH-I337 which is the Galaxy S4, ATT unlocked. When I first got it, it had this Samsung Custom boot and it also was manufactured refurbished. After using it, I rooted it using towel root. I was on Kit Kat 4.4.2 and I saw a post where you have to first something through odin to let towelroot work. I rooted it, wifi worked fine after I put the kernel on. Now I tried to install CWM (I think) and I tried installing a rom which said it was to work with my phone. I wiped cache and everything. And it went through and nothing changed. I was back to my normal phone, with root but the wifi button is not working. Before I flashed the kernel it would go to green and get stuck, now after I tried to install a rom, the wifi wont turn on at all as in the button flicks back to the off position. I have the SGH-I337, unlocked att, I unrooted it, I reset it, nothing changed (ie. batter out, calling *#0010* and something like that). This is in the UCUFNi1 running 4.4.2. PLease help me! Thanks.
Hello,
Welcome to XDA.
If you installed CWM and then flashed a custom ROM with CWM did you do the wipes after flashing the ROM?
If you don't know what that is just boot to recovery, in CWM choose the "wipe data/factory reset", confirm the choice and let it wipe, then choose the " wipe cache" option, confirm the wipe and let it wipe, then choose the "advanced" option, in the advanced menu choose "wipe dalvik cache", confirm the wipe, let it wipe, after that go back to main menu and select the reboot to system option and let your phone reboot and set it all up again then see if WiFi works. Backup any apps and their app data that you want to keep before factory resting in recovery, it deletes your user installed apps and leaves only system apps, your pics and other stuff on internal will be safe, you won't need to back those up anywhere, only the apps and app data get wiped with factory reset in CWM. When it reboots install the backed apps and their data and you'll be back where you are.

I did an update, now my phone starts in recovery mode. I tried "wipe data/factory reset" and "wipe cache partition" but nothing changed.
Now I want to install a different firmware or (if possible) reinstall Android. Can I do this and how?

Happened to me as well. There is nothing you can do. If it's under warranty send it back. That's what i did, they changed my motherboard for free. I suggest you go for it. Just don't mention it's rooted, there is no way they can find out if you don't tell them. Warranty repair isn't repair anyway they just swap boards or give you a new unit for free. Best of luck. Just don't root it again, i know i won't.
So today I wipe my data/factory reset cuz some apps didn't work for me cause it will pop-up "you have a rooted phone" (i have not) and now, my phone just loops the SAMSUNG logo 24/7, i did install TWRP in my phone and factory reset and wiped data, also tried to "repair" Internal Storage but it will pop up "invalid partition selection" also, after everything that i did it will always say "failed to mount /cpfes". And when i tried to flash with ODIN an original firmware just says error. And in my download mode says "device 9, binary 8" idk how to fix this, i tried to flash the firmware from TWRP by an SD-card but it will say error. I tried to just mount de AP in ODIN too but will say Device 6, binary 5.
please help me, i don't know what to do, and i have downloaded the last firmware too.
