Stuck in CWM / Crash on every Rom installations

Hi everyone
Sorry in case of repost.
I have a P5210 (Samsung Tab 3 Wifi). Once rooted everything was allright until I entered in recovery mode from the Rom Toolbox app.
I'm now stuck in a recovery loop mode and can't get out (CWM v6.0.4.7)
I've tried everything from factory reset / cache and dalvik cache wipe, to "fix" zips and so on. But nothing changes.
I've tried to reinstall CWM by putting a recovery image into a script and flash it through CWM. Seems to be done correctly, but when I reboot, it's still the same CWM (no update)
Eventually, i've tried to install some custom ROMs to start fresh : Every installation crashes at "WRITING SYSTEM PARTITION". I get black screen and a reboot.
And I've tried every custom Rom compatible with P5210.
Can you help me to get back to a clean configuration ?

Hi
It seems you were on kitkat rom which may have updated your bootloader to kitkat version. The CWM needs to be updated to work well with kitkat. I had similar problem with my SM-T210, and solved the problem after updating CWM as per this post for T210:

Your tab is different from mine so i think you need a fresh stock rom install using odin, then find an updated CWM for your tab.

[Q] Unable to mount /data

Hi,
I've just tried and failed to install the "cm-12-20150218-NIGHTLY-nicki" ROM on my phone. Specs are:
Official Android 4.3 Firmware
Model: C1904
Timeline:
Unlocked bootloader according to instructions at http://forum.xda-developers.com/showthread.php?t=2484428
Phone then got stuck in official boot animation (the colourful one)
Didn't bother flashing the "Elixer" kernel as suggested in above thread
Used fastboot to flash the boot.img from the CM zip file
Booted to recovery
Wiped data & cache
Flashed CM & GApps from external SD card
Restarted phone
Phone showed big Android robot animation and then went back to CyanogenMod Recovery
Looking at logs showed "Cannot load volume /misc" error
Found a forum post saying this thread helped with the above error: http://forum.xda-developers.com/xperia-m/development/cwm-twrp-recoveries-cm12-lollipop-t2979752
Tried flashing TWRP recovery (http://forum.xda-developers.com/xpe...very-cwm-twrp-recoveries-custom-roms-t3016507) within CyanogenMod Recovery, but it said the file integrity was bad or something
Used "fastboot flash boot FOTAKernel.img" to flash the above, which worked
Tried to wipe data from within TWRP, but got "failed to mount /data" errors
So the phone is now in a state where:
I can only boot into TWRP
I can't use ADB since the program on the computer won't detect the phone
Fastboot still works
I can't boot into Android
Something seems wrong with "/data"
Any ideas about where to go from here?

I was able to use Flashtool to flash the official firmware back on and boot into it as normal. After doing that and restarting the procedure to install CM12 2015-02-19, this time it installed just fine.
Although I still got errors about "Cannot load volume /misc". Hopefully they don't matter...

Now you have CM12 installed and it is working?
Had the same errors when I tried to flash CM12. Flashing CM11 worked fine but I could not get CM12 to boot...

Yeah; it's installed and working fine. When I flashed the official firmware, (Android 4.3) I told Flashtool to flash everything including the kernel. That seemed to put the phone back into a good state, which allowed me to install CM12.
I'm not sure what caused the problem in my case. Maybe it was unlocking the boot loader.

[Q] Urgent Help! Bricked Samsung Galaxy Tab 3 10in

Hello all i have bricked my Samsung Galaxy tab 3
I have tried rooting but it ended up giving me a boot loop
Nothing has worked, I have tried flashing a stock ROM, it was unsuccessful, i have tried a rooted ROM, it was successful though i was still stuck in a boot loop, so i flashed Philz recovery and that worked but it didn't clear anything.
I'm currently downloading another Stock ROM and I hope it works.
I also tried adb and that didnt work either.
How can I stock recover this device.

Have you tried using Odin to return to stock? don't forget to "uncheck" auto reboot. After flash completes, shut down, then restart.
Here's a thread for using Odin to return to stock
...and wipe/format system, data, cache etc before flashing

Which version? P5220(the LTE version) P5210(wifi only version) p5200 3g version
you can try out odin, flash everything including stock rom and recovery. Start everything all over.

My phone won't wipe nor flash a new rom/recovery

Hi there. Here I have my t989 with stable cm11 by Sultanxda and twrp 2.7.0.0 installed.
Everything was fine until I wanted to try 5.0.1.
I got into twrp and did the usual wipe and install ParanoidAndroid 5.0. It failed.
Ok stuff happens so I just went restore my backup no big deal.
Now when I reboot back my phone looks as it were before BUT it reboots after 2-3 minutes in every time it boots back up.
So I thought the power button has problem but soon I figured it is not because my phone won't self reboot in recovery and download mode.
I went back to twrp and try to wipe it clean and install cm11 instead of restoring to my previous backup.
Wipe says successful, install says successful, reboot system. And only to find myself still in my old Rom and nothing was wiped.
All my apps are still there blahblahblah. I tried to update my twrp through twrp manager but phone reboot before it finishes installing.
I grab my odiin and try to update recovery there. Odin says success. Goes to recovery only to find its still in 2.7.0.0
Download a stock .tar and flash it with Odin. Odin says success, boot up and still in my old cm11 rom...
Now I went out of option but ask for help. I have done flashing for 3 years with this phone and I have never gotten this problem before.
Please Help

Help flashing back to stock, tried everything.

Hi, i'm having trouble flashing back to stock.
I've got the latest stock firmware from sammobile.
Using twrp to install it says missing META-INF as the firmware zip isn't made the same as custom firmware.
Adding the tar.md5 to ap in odin flashes the boot and recovery but goes extremely slow when it starts flashing system (left it 2 hours and it hadn't even got half way) I'm guessing that's not normal.
I took a backup with twrp before I started flashing in twrp which flashes fine but I get endless boot loop when trying to start it.
I've tried fastboot but it doesn't detect the tablet.
I've tried different usb ports, cables, different versions of odin and different stock firmware. I'm ready to throw it out the window.
One thing to note is the [P600][Touchwiz] Marshmallow Rom 20170622 works great but also boot loops when I turn it off and on again, I have to boot into twrp then choose reboot in there and then it boots ok, that doesn't work with my twrp backup though.
Anything I'm doing wrong?
Thanks.

Well for some reason after installing marshmallow rom again then installing my backup it boots fine, havn't a clue why it failed to boot the other 4 times.

Nope
Back to continuous boot loop after second reboot.
All I did was turned developer options off and it's boot looping again.
Flashed original stock boot.tar.md5 and recovery.tar.md5 then factory reset and wiped cache but still boot loops.

Is it because I flashed a Marshmallow custom rom so it so you can't downgrade to a lolipop rom even though it's stock? Boot loader changed? Kernel?

I'm not quite sure what your problem is but you should be able to downgrade, I've done it before.
Try this guide first. I've had success with it.
If all goes well you can then try to flash your stock ROM. The one I've flashed successfully in the past is the one in this post.
Good luck!

You may need to repartition your system. Tick the repartition in Odin. **All data will be lost**

Thanks, I followed the guide in that post and it flashed ok then I finally managed to flash the latest stock!
