Flashing Issues - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

Hi guys and gals,
I'm kind of new to this, so this issue may be trivial for most. I have successfully rooted to tab pro 10.1, have flashed TWRP, and have loaded custom ROM zips on my external SD. My problem is that when I try to flash most rooms, it ends up saying failed. The one that does actually show successful(ProPlusV1), will allow me to boot but then shows processes force stopping, and then sends me into a boot loop.
Is there something i'm doing wrong or missing. I searched the forums(maybe not as well as most), and was not able to find anyone with the same issue.
Any help is appreciated!!

Did you do an advanced wipe before you installed the roms? Advanced = wipe system, data, cache, dalvik cache. Then factory reset. This is my standard mode and I don't have problems. Which rom in particular are you trying to install?

Did you try wiping everything except external sd in TWRP? I tried that rom for my 12.2 and ended up with the Samsung logo followed by a black screen and ended up restoring my backup. It's still a test version for the 10.1 and 12.2 so I wasn't expecting much. Maybe try this one: http://forum.xda-developers.com/showthread.php?t=2776206
based on the stock rom that comes with US tablets. The last time I tried downloading, it kept failing at about 75%. I think I'll try again tonight.

Just saw your post after submitting mine. What is the factory reset doing after wiping everything? I'm still fairly new to this.

I have a very similar problem, though I don't consider myself new to flashing.
I did advanced wipe (system, dalvik, cache, and data), though TWRP was complaining about being unable to mount /cache. I also had to select "use rm -rf instead of formatting", because formatting didn't work (recovery would reboot). Then I tried flashing the ROM linked (the GigaWatts Pro), but it would not boot (gets stuck on black screen after boot logo).
Since I had a backup of the stock ROM, I figured this wouldn't be a problem. But now TWRP can't mount /system and therefore I can't restore my backup - it just says "failed".

Try a factory reset? I'm not sure what it does after you've already wiped everything. I've soft bricked my tablet in a similar fashion with the same symptoms as you except TWRP wouldn't even load after a couple mounting failures. Here's what worked for me. I downloaded the stock firmware for my tablet from here: http://www.sammobile.com/firmwares/
Enter your model # where it says "search device here..." and download for your region. If you're in the US you'll want Cellular south. Extract the .tar.md5 file then run Odin 3.09 as admin and install using the AP button. If using Odin 3.07 use the PDA button. I'm pretty sure I had to re root and reinstall TWRP after that. I was then able to restore my backup. I've soft bricked my tablet a few times playing with custom roms. Hope this helps.
I'm fairly new to this, so if I've made any mistakes, someone please chime in b4 Deusdies reads this.

thanks for this. you should also mention the unbelievably long download time of over 2 hours if you're not a premium member of sammobile.

I had the same problem.

[Q] CWM wipe does not work?

Hi you guys. Im have a bit of trouble whit the CWM. Im stuck in a kind of bootloop after updating to latest CM10. It boots up and i can access my homscreen for like 6-7 sec, but then it reboots to bootscreen.
So i thought i have to wipe my data, get it back to factory state. So i do that, wipes cache to. I have even tried the Mount and storage > format /system /cache and /data.
But when i re-install my rom allmy apps, wallpaper and that, are all where i put them. I can even mange to open some of the apps whitin the 6-7 sec window i have before the phone will reboot. The CWM says it done all things right. No error messages at any time ...
Any one whit an idea to get this back on track ?

are you wiping data(factory reset) or are you just wiping your dalvik and cache?

OK do what simms22 has explained. That should work.
But from what I am interpreting is that you are doing cache not wipe. So you go to "wipe data/factory reset" menu and hit/press yes. It should wipe it and done. BTW it might have been in a boot loop because you might of dirty flashed or you didn't wipe cache and dalvik cache. That is very important to remember. Never dirty flash and also wipe cache and dalvik cache.
Also did you play with tweaks and such before this was happening. Like voltage or over clock because that could be the problem too.
Dalvik cache and cache are hash signed by the last rom that was flashed. New rom, new hash sign. No need to wipe caches, just data.

Cwm is notorious for failed wipes.
Definitely upgrade to twrp, and if your phone is so messed up twrp can't wipe it, use the android revolution wipe script.

If you're backed up and don't mind losing EVERYTHING, yes, EVERYTHING in /data, then boot into fastboot mode and run
Code:
fastboot erase userdata
from your computer. (Might need root privileges if running on Linux)
Hi guys. I got it to work finally. I didt some tweaking whit the DPI. Maybe that was the cause of the crash ??
But i went to use the Galaxy Nexus toolkit, first of all to flash the other recovery program. But since it dint work either i flashed it whit sock rom, from the same toolkit at started all over. That did work, but hell of a way to go

An odd situation please help?

Okay so to start off I had RSL14 Hyperdrive installed on the rom, ended up trying a new one and when going to wipe data, cache, dalvik, system as usual i ran into an odd error. I am using TWRP recovery and when going to wipe data, the phone just restarted, so i rebooted into recovery and tried again same thing.....which was odd. So i reinstalled twrp and then tried again same thing. Then I decided to install CWM 6.0.1.2 and it wipes data and everything fine, but when going to wipe cache, dalvik, or data it sometimes states E: unknown volume for path {/sd-ext}. On top of that everyonce in a while it says E: unable to format unsafe partition?
Please help its causing me problems and I am a flashaholic.

Sean

Unsafe partition usually means your internal partitions got corrupted somehow.
I would suggest to flash a stock ROM via ODIN or ADB. You could try MSkips toolbox if your comfortable using it-http://forum.xda-developers.com/showthread.php?t=1703488

If I flash the stock recovery via odin will this fix the partition? I'd really hate to have to do that but reflashed both recoveries a couple different times and like the rom im currently on but if it must be then I guess I have no choice.

I think you need to flash both of them over.

[P-600] Bootloop after trying to wipe Cache+Dalvik in TWRP.

I tried to root my wifi Note 10.1(wifi) using TWRP and the SuperSU flashable zip, but when wiping cache and Dalvik the tablet shut down. Now when I try to boot the device it only plays part of the boot sound and gets stuck on the "Samsung" logo. I've tried searching for ODIN flashable stock firmware, but with Hotfile being down(sammobile's file host) and the rest requiring a paid subscription to their site, I'm screwed.
I've tried using Kies' emergency recovery option, but it won't recognize the device as needing recovered. When I try to search for updates through Kies it tells me the model name is invalid(P600, SMP600, SM-P6000ZKYXAR, Galaxy Note 10.1 2014).
I can still boot into download mode and TWRP.(I REALLY should have made a backup first.)
All I need is the stock US(XAR) firmware, preferably ODIN flashable. I'm not sure if I trust TWRP to flash it just yet considering it crashed wiping dalvik, but if it's my only option I'm willing to try it.
I have seen somewhere that TWRP is a bit temperamental on our devices with wiping cache, and you sometimes have to do it twice, have you tried it the 2nd time ?? Use the advanced menu, wipe cache and reboot.

It took a long time to finish, but it successfully wiped the cache the second time and booted successfully! Thanks for the link by the way.

[Q] "gapps stopped" loop after CWM restore

Hi,
I was frustrated with the delay in T-Mobile's release of KitKat for the GSIII, so I decided to root my phone last night in order to try flashing CM11 on it. Rooted my phone with Towelroot, installed ROM Manager and CWM, and created backups on Kies and through CWM. Then I proceeded to do data wipe/factory reset, cache wipe, and /system format. Tried to flash CM11, but got a status 7 error.
I freaked out, so I decided to restore everything from the backup I'd created. Restoration seemed like a success, but now I get the error "Unfortunately, the process com.google.process.gapps has stopped" in an endless loop, and it prevents me and any apps from doing anything. I tried clearing dalvik cache in recovery, but the problem still persists. Read on a few threads that I should flash to stock firmware via Odin, but I'm currently on a macbook, so I can't install it.
tl;dr - Prepped to flash CM11, reached status 7 error, got freaked out, and did restore via CWM, only to get infinite loop of gapp crashes. No access to Odin or PC. Not hard bricked or soft bricked, but essentially useless phone. Help? );
if you can still get to recovery, download latest gapps and flash that
Did you factory reset before or after you restored your back up?
Yeah, I've tried flashing gapps--no avail.
And yeah, I did factory reset/data wipe, cache wipe, /system format 3x each before attempting to restore. Was that wrong? /:
Try to factory reset again

If I'm not mistaken, there is some device ID that will change each time you flash a new rom. It may be something to do with this ID not matching the one in the restored data. Purely a guess but seems logical to me.
Anyway, factory resetting will most likely solve this for you, but I wanted to add that except in certain circumstances, you shouldn't ever manually format /system. (and one format on any partition is sufficient. There shouldn't be any need to format multiple times). If you format /system, you are wiping the O/S off of your device. Then what happens if you have problems flashing a rom, or firmware? I've seen it happen many times and I often end up spending a couple of days working with them just to get the thing to boot up again!
When you flash a rom, the first thing it does is format /system. So there is just no need to do this manually. At least if the rom fails to flash (such as failing the assert checks), youll still have something to boot into. Hope this helps in the future!
I have had the exact same issue. I have a Samsung note 2 N7105. I rooted made a backup in CWM and flashed ditto n3/s5 rom made another backup in CWM. No issues. Got a bit cocky seen as it was my first time doing anything like that. My next adventure was to try a custom kernel (agni). This didn't go so well, so I tried to do a restorw to my working backup of ditto n3/s5 rom through CMW. restore went smoothly and the phone booted. once I opened the lock screen I got the gapps error as described. I had to do a factory reset to get the phone working and then re-flashed ditto n3/s3. I've since flashed other roms and when ever I try to do a restore, I get the issue described. Note I am using the latest CWM. I putting off flashing and trying any other ROMs because of this issue. I do love dn3/s5 but id love to try others. Anyone can help it would be appreciate.

Wiped Internal Storage; now phone reboots on loading ROMs

Hey guys,
So last night I accidentally wiped internal storage in TWRP. I guess that messed up my partitions or something, I don't know. Anyway, I can still access recovery, and I've tried to do a restore (one that I made back when I was on stock 4.4.2 I think) but after that it tries to boot, gets to "Android is upgrading... Optimizing app Y of X." and once that operation completes it shows the lockscreen for about a tenth of a second, and the phone reboots.
I'm stumped. Anyone know what can I do?
Sorry if this has been asked a hundred times. For some reason the search function in the forums isn't working for me. And I've been looking for a solution all morning.
EDIT: FYI when I tried the restore I did only System and Data and not Boot, because I was afraid that'd cause more problems.
Did you try restoring and performing a factory wipe before booting the newly-restored ROM?
It seems that Marshmallow based roms aren't working, but Lollipop ones will boot. Not sure why as I didn't have any problem with the same MM roms in the past.
More info:
MM roms wont flash in TWRP; after the failed attempt, TWRP says system cannot be mounted until I either wipe or install a 12.1 rom.
Tried to install a stock rom (4.4.2) and it failed in TWRP. Just says "Error Flashing"
Are you performing a full wipe (system, Dalvik, cache, data) before installing or restoring a ROM? Is the phone running the latest version of TWRP?

Yes to full wipe. TWRP is 2.8.7.0, so yeah I think it's the newest? Not 100% sure.
Wiping internal storage should not affect the partitions. I'm not sure that TWRP even has the ability to change partitions.
Yes, 2.8.7.0 is the latester version of TWRP.
If you are on the nj2 bootloader, try flashing this in TWRP: http://forum.xda-developers.com/galaxy-s3-att/general/rooted-ucufnj1-stock-rom-t2985006
Welp, seems to be all good now. Not sure if I really did anything to fix it or not. I tried to install a stock ROM but it wouldn't boot (stuck on Samsung logo) but after that my CM13 ROM installed properly again. The one CM13 ROM I have still wont install at all - maybe that file became corrupt or something? Not sure if that's even possible.
Either way I'm all fixed up. Thanks for all your help.
Cheers
Glad you got it sorted out. If you do figure out what you did to get it working, post your answer as it may help others that are in a similar situation.
