Ex Demo Reset - Galaxy Tab 4 Q&A, Help & Troubleshooting

hi
Got a tab 4 ex-demo model, i have used the firmware and odin to reinstall os but it only updates
following all the instructions for reset but the vol + and home doesnt allow factory reset so have to do it through odin
any advice the only thing i can think is to use nand erase and reinstall boot loader but everyone says stay away from nand

A bit confused about debranding i5801

Hi all,
I have an i5801 with all the usual orange crapware.
I'd dearly like to lose all that and turn it into an i5800 with the standard samsung firmware. I don't really want to root it, and i do not need to unlock it.
Is it as simple as downloading a rom (I5800XWJPF) and flashing it with odin as described in this thread?
Should I get a rom with the bootloader removed? or an entirely stock one?
Once this is done, will my phone basically actually be an i5801 and then be updatable via the normal channels?
thanks for some guidance. It's a little confusing (too much information out there)
slip
i think u can just flash xwjpf when u flash the bootloader ur phone will say i5800 when it boots. when u dont flash the bootloader it says i5801. without the bootloader is safer u dont need root to flash a rom
You can simply flash a i5800 stock ROM, with the bootloader
I've done dozens of flash with bootloader and never hardbricked my phone, so I think it's quite safe.
thanks chaps.
how do i factory reset / clear cache (as mentioned in the guide)
i have tried vol+, vol- home and pwr but it just takes me to the downloading screen, not a menu.
you have to press Vol Up + Vol Down + Home + Power on
its a bit tricky
i could never get into recovery. before I flashed, vol+,vol-,home+pwr just started downloader.
adb reboot recovery just rebooted the phone.
So i flashed anyway. Still could not get in with vol+,vol-,home+pwr but managed to get into recovery via adb.
cache cleared and reset, and now i have an i5800!
thanks again
let the boot loader remain.dont tamper with it.chances of hard bricking are less when you leave the boot loader files intact

S4 i9505 stuck at Samsung logo-can't access to recovery boot

Bought an Australian model galaxy S4 off ebay which was stuck at Samsung Logo with a hope I can unbrick it.
I have tried to flash with an official firmware twice. ODIN confirmed flashing Passed. But the phone still could not boot pass Samsung logo with model number.
+ Pressed volume up + Home + power button to enter into recovery mode but the phone still stuck at recovery mode with blue text "recovery booting ". Have tried to take battery out and redo few times. . All I can do is go to download mode to flash official firmware again. However I do not want to mess thing up as I have tried twice without success.
Please help me out if you have any idea how to fix it. I am much appreciate.
I am not sure if it will help or not but you can try flashing TWRP via Odin and then boot into that one (maybe recovery is corrupted as well?)
Clear cache / dalvik cache from TWRP and try booting to system again

Good idea of @th3cr0w.
I will add: It's important know what firmware had before you start to flash things. I supose you don't know it. What you can do is:
1. Flash TWRP recovery in DOWNLOAD MODE via ODIN unticking "Auto reboot". Take out the battery when the process finish. Wait 30 sec. and push it in again.
2. Boot in TWRP and wipe all (Wipe -> Advanced Wipe -> Select system, data, cache and dalvik cache).
3. Reboot in DOWNLOAD MODE and now yes, flash the firmware you wish via ODIN normally.
Same happens with my Galaxy s3 while ago, Problem was the EMMC chip was corrupted, And the problem was solved after replacing it from a local shop.

Thanks for your and TH3cr0w's suggestion. I will try it tonight and let you guys know. Hope I will fix it. A quick question before I do, once I install TWRP it is anyway I can remove it and reinstall official receovery?
I am using this firmware:
PDA I9505XXUGNH6
CSC I9505XSAGNH1
i have tried to install TWRP with this file twrp-2.8.6.0-jfltexx.tar 9.9M. However my phone still stuck and can not boot into recovery. up the top of screen i have following messages:
Recovery booting...
RECOVERY IS NOT SEANDROID ENFORCING
Set Warranty Bit : recovery
Have i done anything wrong? Thanks
What you're seeing is normal, but recovery not installing isn't. I know you don't want to try it again, but flash your stock ROM through Odin. Do it this time with the following changes:
Add a PIT file (easily found on the forum).
Make sure "Re-partition" is selected.
The combination of the PIT file and the re-partition function should wipe the S4's internal storage and partition it properly. If there is no physical damage to the internal storage you should then be able to boot into the device. Otherwise you may have no choice but to have this beast repaired.

Root for SMT330NU Galaxy Tab 4 8.0 Android 5.1.1

Has anyone successfully rooted the OTA version of 5.1.1 lollipop? I tried CF-Autoroot, and soft-bricked my tabled... I got a "Pass" using Odin 3.7 and 3.10 but each time it only got back to the animated Samsung logo and got stuck there for hours. Only way out of it was to hard reset, and then re-flash a stock 5.1.1 downloaded directly from Samsung... I am just wondering if there is an updated Towelroot, Cf-Autoroot file, or some other method which will ONLY give me root access. I don't want to which from stock rom, because there isn't a custom one with ALL features working properly. Any help would be greatly appreciated. Thanx
*Also again, if you tried any root method and you are stuck at the animated Samsung logo, then just boot your device into "Download" mode by powering off and then powering back on holding "Power + Down Volume + Home" keys, then press UP when asked if you want to enter DOWNLOAD mode... then flash the STOCK 5.0.1 or 5.1.1 firmware using ODIN 3.10. Click the "AP" tab, then choose the stock firmware file, and don't change ANY options.
Begin the flash, and it will take maybe 15 min and your tab will boot back up no prob. If you DO encounter a problem while flashing, then reboot into recovery mode by powering off then power on holding "Power + UP volume + Home" then choose "Wipe Data Factory Reset", then "Wipe Cache", and then REBOOT. Then Perform the first steps listed again (Download mode) and try the Odin Flash again. This should work, for any SMT330 device, I have tested this method myself.*

S4 AT&T(I337) Recovery Boot Loop - Need help!!!!!

A client brought in her phone (S4-i337) that was in recovery mode, at first i thought it was something simple but not really. At first i did a wipe data but it couldn't boot up instead after rebooting, it went back to recovery mode. Surprisingly, this phone boots up normally when you try to boot to download mode. As in, when i press Volume down + Home + Power, instead of it going to download mode, it boots up fully then i happen to use it for until when I restart it. I've updated it to Android 5 using some file that i found on some forum, thought it would help but same case. Members, am out of ideas on what i should do. I've flashed it with Z3X box, but i also get an error, same as Odin. Any help is highly appreciated
What are you flashing to the phone? If it was running a stock 4.4.2 ROM or newer, the bootloader would be locked and AT&T never released a complete Odin firmware flash after 4.1.2.
