[Q] Failed upgrade to JB 4.1.2 on Chinese P6800 - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

Hi all,
after successfully upgrading my Hong Kong P6800 from ICS 4.0.4 to JB 4.1.2, things went rather south this morning.
screen shot of my current ICS version.

I tried to use the same md5 file (KIES_HOME_P6800DXMD3_P6800OLBMD3_1157844_REV00_user_low_ship.tar.md5) with Odin v1.85.
At the moment the Odin started to write NAND with the factotyfs.img, ODIN stopped and interupted the flashing process.
I managed to revive the tablet, by re-entering the download mode and flash the CWM 6.0.3 tar file.
Flash was ok and luckely the TAB rebooted :highfive:
Who can tell me what I did wrong, or is the simple fact that the chinese P6800 can't be flashed with this ROM?

I wouldnt give up hope yet...
Get goo manager from play store...then get TWRP...
(make sure you have root access first)
from here you can have a plan B to install it.
look for "erobot rom thread" and i think the origonal stock rom is available as a downloadable zip.if not skyhigh or someone had it on there rom page.or else just use the new erobot skyhigh etc...there based on the stock one but modded..
then you can flash it with TWRP...
before flashing...
make a back up of your rom to sd card..
then do the full wipe..
eg 4wipes....1 cache 2 davlik cache 3 factory reset 4 system..
then install erobot or stock rom zip from sd card..
then RE wipe everything again...without restarting tab
re flash the rom again and should be no probs..
now reboot and should load up...
If flashing roms doesnt work I just wipe everything properly and flash twice and always works.If wont load or boot loop then need to redownload rom again and check the file size agaisnt what you are downloading vs what you have when finnished downloading to make sure its all there this will cause it to bootloop if not full file.
if still fails to boot up then go back to your back up from sd card you saved and do recovery...now you can try mobile odin or something else,but i always use TWRP and never have a problem.

Thanks MRBR7! ur suggestion was spot on. I've e-Robot running now

Glad it worked..
I Bought mine in Hong Kong too....P6800
Erobot V2.2 is my fav Rom at this stage.

[UNBRICK & ROM & ROOT] G9300 {e1920_v77_zlh_fwvga}

New version of tutorial: http://forum.xda-developers.com/showthread.php?t=2288124
[ROM & ROOT]
Here we are going to install a mix of two ROMs in order to make the phone usable again..
You need to download these files;
SP Flash Tool;
http://www57.zippyshare.com/v/6833714/file.html
e1901;
http://www.4shared.com/file/9bsP-vQV/
e1920 (this should be original system, but when you install just this,
some red triangle appears and system will not continiue to load, so just do it like I will show you in this tutorial);
http://pan.baidu.com/share/link?shareid=506476&uk=4178083362
Then, first you need to flash entire e1901 ROM to your phone, using flash tool..
After that you will need to flash only first six parts of e1920 ROM, it is shown in Pic0;

}
Also then download this; http://www47.zippyshare.com/v/70264800/file.html
Flash that recovery.img alone without any other part of ROM (that is Clockworkmod Recovery PORT)..
Now download this file; http://www47.zippyshare.com/v/52522093/file.html
That is ROOT for your phone, you need to put that file on your SD card and then put battery in your cellphone, pres Volume UP and Power Button together, that will send you to CWM recovery, from there install that file from your SD card, and restart your phone..
If it forces you to CWMR, just flash again the first six parts of e1920 ROM, and when you start your phone it should work fine..
But now You will have to SET your IMEI number becouse this is factory ROM, I am actually not sure how to do that, becouse I did not need that ( ..I have my CWM backups from before.. ..) ..so on that one you are on your own, but yes now you have ROOTed working phone again so it should not be that difficult to pull that off..
[UNBRICK]
Now I will post some pictures on how to unbrick your phone in case you get it hard bricked by trying out some other ROMs..
You will need to conect KCOLO and GND(or any other ground surfice on the phone), connect your phone with USB and start flashing the ROMs (like it is explained earlyer), pictures showing how to connect your phone and create a "jumper" are Pic1 and Pic2;
Pic1
Pic2
This will make your phone usable again.. and it is very stable.. maybe later I will try to make even better ROM, but for now this is it..
Special thanx to Mr. Dirk from ColonelZAP who helped me with unbricking the phone!!!
If this little tutorial helpd you just remember to hit THANX button.
*** UPDATE ***
Okay here is the way to enter you imei number;

It will work for sure!

Bricked?! SGS6 920F can't mount "/data" or internal Storage after flashing Bootloader

Bricked?! SGS6 920F can't mount "/data" or internal Storage after flashing Bootloader
I was running XtrestoLite DeoMod Edition 2.4 on 5.1.1 on my German Galaxy S6 64GB when i decided i want to upgrade to 6.0.1.
So i downloaded all needed files here:
http://forum.xda-developers.com/gal...xtrestolite-deodexed-mod-edition-1-3-t3119968
After i had flashed the 6.0.1 Bootloader, Modem and TWRP 3.0.0.0 (which i also found in the thread above), i was stuck in TWRP, as i couldnt perform a Wipe anymore. For some reason it won't mount my internal Storage and some other partitions anymore, for instance "/data". So basically i can't flash any 6.0.1 Rom but i also can't do a FULL WIPE.
I have already downloaded the 6.0.1 Stock ROM from SamMobile and i am ready to flash it via Odin, but i'm worried it will Wipe all my data! As already mentioned, TWRP wouldn't show me my internal Storage and mark it as "(0MB)", so it seems like it's already deleted, which is the worst thing that could have happened to me, as i lost crucial data.
My Question is: Why will TWRP NOT show me my Internal Storage and say it can't mount "/data" and all the other folders. Is it Softbricked? Why would Flashing a Bootloader and Modem literally destroy my internal SD Memory?
I want to Flash the Stock ROM, hoping it will fix the Problem but i want to see if you guys can help me Get my Data from Internal Memory first! Please help me!
Thanks alot

flashing a rom in odin should not erase your internal storage as long you dont select wipe in odin. in your case you must flash the latest stock rom in odin. if your storage seems deleted after flashing stock rom. it happened earlier while messing around with twrp. also you should try twrp 3.0.2. viel glück

how can i fix it ?
Probably bad flash/ota. Happened too me as well. I had to reset to stock and reflash via Odin. Make full backup of your device, then try to get back to stock.

can you please describe little bit more ...
you mean i could wipe data with twrp recovery mode ?
or should use odin to install the same firmware again or what ?
What? No. Didn't say anywhere to root. Get to bootloader, use odin and flash original samsung system.
How to make full backup of the device if u arent rooted??
Don't root and fiddle around if you don't know what your doing. Or at least get enough information about what your doing before doing it.
this happened to me after flashing stock FW with odin and then flashing custom recovery without first letting the phone to boot.
After flashing CSC, the phone needs to go to revocery and finish the flashing process (copy CSC files to system). If you flash custom rom, it might not be able to flash the zip and therefore you have no CSC and get weird settings.
I was able to flash the zip with custom recovery by remounting system as read-write first.

Bootloop on Samsung Galaxy S3 with TWRP and Lineage OS 17.1

Hello guys, so basically you are my last hope since I cannot find a solution for my problem (at least with my level of knowledge).
Lets start from the beginning: I (someone with no experience in this topic) decided to try out a new OS on my old Samsung Galaxy S3 since a lot of apps stopped working on Android 4.3. I tried a tutorial on youtube on how to install a new custom ROM. I installed TWRP (3.5.2_9-0-i9300) and later with the help of TWRP Lineage OS 17.1 (an unoffical version for my type of phone) and everything worked perfect.
I started to download all apps I need and to customise my OS. In the end when everything was set up I decided to do a full backup using TWRP and thats where the problem started. In the development section I checked the function, that when you press the power button you can directly boot your phone into recovery mode. So my phone rebooted and ended up in a constant boot loop where at first the Samsung Galaxy logo appears (first picture) and then TWRP appears (second picture) and this process goes on and on...

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Sadly there is no way to get into recovery mode since this loop just continues. If tried it many times also with taking out the battery and putting it back in. The only thing I have access to is the download mode.
So my question to you: is there anything I could do in the download mode to solve this problem? I saved the important data before so a full wipe wouldnt be a problem. Maybe I can do something with odin?
I really hope you can give me some ideas to try out. Every help is appreciated. Thanks!
Try reflashing a stock ROM first of all.
Then reflash TWRP. Make a TWRP backup (especially the EFS ! That is a "must-do first and foremost" !) of your working system and progress from there.
And in the future, instead of reinstalling all your apps piecemeal I strongly recommend you use Titanium backup (paid version. The free version is very limited), that is a wise invesment for the small sum it'll cost you
@Snakeforhire reflashing stock ROM worked, thank you so much.
I will take a closer look on Titanium backup. Used it in the past but with root access. On the new Lineage OS I dont have root although it shouldnt be hard to get from what I read.
