Have you make a backup befor you flashed The Rom?
For this Rom you need always The newest Recovery Version,depent of New updater script.
Can you go to The recovery , make a factory reset and wipe cache / dalvik.
Then go to download mode and flash Stockrom again.
Then flash Philz recovery, after flash Boot manuly into recovery make an backup and now reboot your Tab Into recovery make an fullwipe and flash your New Customrom.

Im using philz tuoch and i habe no prob.
At philz have check The Mount point (sdcard or sdcard/0 )
If these all not hell flash CWM.

I have no clue what i did with it, but this is on the screen:
Odin Mode
Product name: SM-T210
Current Binary: Custom
System Status: Custon
HW REV: 0x5
It has an image like: Tablet......Yellow triagle with an ! in it.....Computer.
Under that it has the text: Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again. But Kies can't connect to the device. I have no clue what i did all ....
Experts please help !!!

hey
in philz recovery, in wipe options select - clean to install new rom
the goto tab 3 7.0 area get svelte rom , you need to put it on removable microsd with card reader [get one]
the put card back in tab reboot to recovery and flash, firmware updates aren't always good or necessary,
odin should be a last option. stay calm [use the force] and good luck :good:

Its funny its only work when you factory reset, My guess would be that something wrong with twrp or updater script.*
Maybe @gr8nole*will know more bout this issue.*

While flashing a recovery for the first time over stock, you need to uncheck the Auto-reboot option and directly boot into the recovery from Download mode.Once you are in the recovery, flash Fix-Recovery.zip to give CWM proper permissions, then your recovery wont revert to stock Samsung recovery on each boot.
You only have to do it once you are on an untouched firmware, you can update and switch recoveries without worrying about it again.

Take the 4.2.2 recovery tar file from here : http://forum.xda-developers.com/showthread.php?t=2315529

THANKS MATE ^_^​

[Q] My T110 won't boot after installing CWM

So I followed the instructions from this thread: http://forum.xda-developers.com/showthread.php?t=2674649 to install CWM and it went fine but when I got out of the CWM recovery menu and rebooted it just rebooted back into the recovery.
Then I guessed it was fine because I was going to install this rom anyway so I followed the instructions and did a factory reset and then tried to install the rom from the zip.
But then the installer failed saying "format() expects 5 args, got 4 - Installation aborted" and I'm stuck with just the recovery menu.
Does anybody know how to bring it back to life?

Thank you so much. This post should be mentioned in the troubleshooting or something I guess it's not that uncommon
EDIT: The ROM flashed correctly but it still loops into the recovery

one question, have you install the quick boot app?
I think the onlyest way for you is flash the stock rom with Odin.
full reboot
flash the recovery with Odin,after flash boot with the button comby into recovery and flash the superSu.zip from chainfire
reboot your tab
open SuperSu.app and you have got root
Dont install the Quick boot app !!!!!
That was the way what works for me.

I don't know what the quick boot app is so I guess I don't have it.
How do I flash a rom with odin and where do I get the superSu.zip from?

Solved
Okay I solved it.
I flashed the stock rom from here: http://forum.xda-developers.com/showthread.php?t=2780068 (the full version no the lite)
using Philz Touch: http://forum.xda-developers.com/showpost.php?p=50922322&postcount=4
And then I just rebooted the system and it took a long while but it finally went past the welcome logo and started fine

Can you get into fastboot mode? If so, does your pc recognize your device? And just a funny FYI...

Back stock rom and preserve twrp ?

Hello ! I have an A70, I installed Havoc OS and it's.... well I dont like it. I want to back stock rom.
Can I flash stock rom via twrp ? (same way as I installed Havoc or lineage)
Can I flash ONLY system.img ?
My idea is to install stock rom and get root access with magisk at the end.
My problem is I cant find any good informations about that !
All I read is contradictory....
on guy say it's ok to flash only system.img via twrp, other guy say to flash boot.img +recovery.img+system.img and use Odin, never flash stock rom with twrp.
I just want to get back to stock rom and flash magisk again....
any help about the right procedure to install stock rom and flash magisk again ?
thank you....

I don't know about twrp, if you can use Odin it'd be better.

thank you for your answer.
1 - so if I use Odin, I just need to flash AP section ? Or the full firmware ?
2 - recovery will be back to stock too ?
I want to preserve twrp.
3 - I just need to fash twrp right after flash Ap.tar/full firmware ? (without reboot device between the 2 flash)
Right ?
need help to understand how flashing stock rom works (via Odin or twrp).
I already wiped data, system,cache partitions from twrp and now the phone only boot in twrp (the recovery) no system installed.
I just want to get back to stock rom (because I have NO system installed) with twrp which is patched with magisk ( to have root access) simple but I cant find the good procedure...
I am able to install Havoc or lineage, but they doesnt suit me.
I want to flash stock system only.... simple but no answer anywhere...
I can extract system.img.ext4.lz4 from the ap.tar. Then I extract system.img.ext4 from system.img.ext4.lz4.
And cant extract system.img from system.img.ext4 to flash it with twrp. I just miss this step and the answer is nowhere. Like the answer which files can be flash with twrp...
need procedure, every tuto is contradictory....

Flash every file that comes with the stock rom, that's how you get it back. I don't know about root, I'm not rooted.

I don't know of a way to flash stock using TWRP (and preserve TWRP).
Quickest way might just be to:
- Flash back to stock firmware using ODIN in Windows (phone in download mode). This will wipe everything of course, including TWRP (I found).
- Follow the unofficial TWRP installation for the A70 [RECOVERY][UNOFFICIAL][ROOT] TWRP for Galaxy A70
