Develop Bugs

At&t gn2 hard bricked??

I upgraded to 4.3 stock. Then rooted, then upgraded to 4.4.2 custom.
Then decide to get back to 4.3. By a mistake i restored in ODIN to 4.1.1 (stupid me)
After restore, phone won't boot. Actually I cannot do anything......except for going into download mode, where I got "knox warranty void:1". And that is it! Nothing else can be done........i cannot even boot into recovery............
Any help??? Or should i toss it against the wall??

TY!! I did that already..........and STILL cannot boot into recovery AFTER this.... any idea???

Your profile says Verizon. This stuff is for at&t.
But you can reinstall TWRP if you can get in download mode.

VERIZON?? Oops!! That was years ago.....forgot to change it. Sorry.
And yes, i did install recovery via odin. But i cannot boot into recovery.....

Home+volume up and hold in power until you see first screen, then let go of power but contine to hold in home+volume up until you see TWRP screen.
Otherwise, use "adb reboot recovery" command.

Yup.

Mine is doing the exact same thing. Wont show up in adb and wont boot in recovery, but can get in download, flashed twrp through odin and still cant get into recovery

There is some procedure that forces recovery that involves taking out the battery at a certain point during bootup, but I don't know it. Maybe start a new question thread about that?

Try flashing the 4.1.1 firmware from sammobile. it is the older of the 2 from att and it does not show a version number on the Sammobile site. Then flash root/cwm all through odin. Then do the battery pull trick to recovery. You may need the root and custom recovery to get the rest to work right.

Done that, NO luck.

When you pull the battery does it boot automatically into download mode? Or do you have to power the device up yourself?
Also have you tried to odin a root injected 4.1.1 fw yet? You may have to dig through the dev section but I know they are there.
Have you tried flashing the leak 4.3 yet? http://forum.xda-developers.com/showthread.php?t=2496292

After battery pull out, I have power it back on. (power-home-vol/up - Galaxy Note II screen, and sits there. power-home-vol/down - download screen)
Tried 4.1.1 in odin, tried 4.1.2 as well, and rooted it in odin right away, all went OK, passed, but after battery pull out, still didn't go beyond Galaxy Note II screen.
Tried 4.3 in odin, but at the end, got "failed" result.
Damn.............for some reason, i know this has something to do with bootloader. I am not "android" guy, but rather PC computer freak... ......if i only know how to completely reformat entire storage space, and start from the scratch.....but unfortunately, this is not a hard drive....

Just for me try this: flash 4.1.1 and as soon as the device reboots pull the battery. Dont let it get a chance to do anything. Then boot it into download mode and flash the chainfire superuser with Stock recovery built in. That can be found a in the stickey how to revery to stock thread in this exact forum. Then on reboot after flash pull the battery and let it sit for 5 min, no less. Then try to boot into recovery. If you can get into stock recovery there is hope.
I know you may have tried this already but please try it one last time for me. Keep in mind you should pull the phone Off the usb as soon as the odin flashs are done. Pulling the battery while it is still plugged in wont cut the power the way you need it to in order to reboot properly. Also if you have an external sd card in pull that sucker out as well. Sd cards can hang things up sometimes.
Like I said spitballing here. If all else fails maybe you can talk a dev into wrapping a rom into an odinable .tar file and try to force a rom on it.

Cool, let us know if this actually worked. This seems to be a problem for 1/2 the people that try the revert to 4.1.1 method.

[Q] bricked tab s

Hey guys,
so I really messed up. I don't blame anyone besides myself.
Just seeing if you guys had any ideas that would help.
So I have a tab s t807 which is now bricked.
I did root and flash twrp which went perfect.
Since I don't use my mobile data for my tablet I decided I would flash a t805 rom
I knew it would work fine just data would be a Problem.
Now here's my mess up. I really wasn't paying much attention.
downloaded the Ironman t705 and flashed it. Huge mistake I know!
Now my tablet screen won't turn on. I can boot download mode
Can't figure out how to get to recovery.
I work for tmobile and now they don't do warranty for that tablet,
also my knox count is at one. So I can't go to samsung.
Any ideas? Thanks for the time for reading this.

If you're lucky, perhaps it will let you go to recovery.
I struggle with this from time to time and it eventually works.
Good luck.

Hello.. So twrp works for T807T? Good to know. Anyway your gonna have to flash stock tmobile firmware if you can accesse twrp. Have you tryed doing adb reboot recovery on your conputer?

Bit confused, surely if you can enter download mode its just a case of flashing a t805 firmware?

See that's what I thought. But kept getting a failed message in Odin. USB, drivers are good. And just before that. I flash twrp through Odin

I am downloading a Tmobile firmware now and will mirror it tommrow. Hopefully the download doesnt fail

As long as you can get to download mode the tab should be recoverable. Whether that be flashing a custom Rom, stock rom or a nandroid through twrp. I have soft bricked more times than I can remember, but always recovered through download mode or custom recovery.
I have even recovered from a total hard brick many times as I have jtag equipment which I needed for recovery when developing and tinkering with previous devices. As yet I don't see a jtag option for the tab s, so I'm not to keen to go messing too much.

Download: https://mega.co.nz/#!ylYEBA4D!yWUPtuT60dLCIy_zCN_rqnN2L319oZYSCSFtOC_Pv6Q
This firmware is for the T807T (T-Mobile) devices! It took me 14 hours total of download and uploading it to a fast server.

[Q] And I mannage to soft brick....

Hey guys me again, I have been trying since 2 hours to unbrick my 2 days old Galaxy tab s 10.5, After successfully rooting my new tablet I decided to make a back up of my stock system, I used TWRP recovery to do so, after booting successfully on TWRP, I wanted to make sure I will have a clean image, I manually erased every possible thing on my table by selecting every option on TWRP, once done and on my way to reboot, before quitting TWRP warn me that there wasnt any system, and even with this warning I quit. Result I bricked my tablet hopefully "soft", to get even better I remembered that I didnt had a micro sd card on my tablet and by consequence I must have erase TWRP and every possible restore solution, the table get stuck with the Boot logo and thats it... I can get at least into download mode,. I tried Kies 3 but Im getting an error that my device is not recognized and for Odin I do think is connected but I dont know how to use or what to install or what to do. And I don't get it why my program seems so buggy and I can´t select any of those options.
at least I could root my phone easily.
ps: I did try every possible combination to get into recovery mode and is just impossible there is no way.
if anybody rescue me I seriously cant thank you enough I googled around and did search a lot on the XDA forums, I'm now more scared to tweak around and make things worst , and maybe if not to late permanently dammage it.

Hey maxal, thx for replying, my English is really not the best, if you think its not understandable I will re edit and try again.

You will need to find and download your firmware from Sammobile http://www.sammobile.com/firmwares/database/SM-T800/BTU/
and use odin to reflash your stock firmware.
Read this too. http://theunlockr.com/2014/08/09/how-to-unroot-the-samsung-galaxy-tab-s-10-5-wifi/
TURNING THE DARNED THING OFF:
Here's the problem. If you are at the Samsung splash screen or boot looping Recovery, you cannot turn your tablet off by just pressing the power button and you can't pull the battery. This prevents you from getting back into Recovery or download mode to restore your nandroid backup or use Odin
So here is what you do:
1) Plug your tablet into your computer (this is important!).
2) Hold down the home, volume down and power buttons until you boot into download mode. Once you are prompted, push the volume up button to enter download mode completely.
3) Now, once in download mode, hold down the power and volume down buttons (not the home button this time) until you screen goes blank (your tablet MUST be plugged into your computer for this to work!). Release the buttons and you will see the battery symbol on your screen. Your tablet is now off - thank god.
4) To enter Recovery mode, hold the home, volume up and power buttons down until Recovery loads.
5) Restore your nandroid backup if you have one.

I believe kIes is for stock unrooted devices and Odin is for rooted devices, I may be wrong. I did get my self in a mess and I was stuck on the Samsung logo and with the help of the forum and what I have told you I managed to get my Tab S to turn off, I then boot in to download mode and used Odin to flash stock firmware again

Hi maxal,
Download via KIES will not check root If you do not connect the tablet to a PC. It only checks the serial number and model type of your Tab for search new updates firmware with determine the correct CSC Region code. You can even download the correct firmware by KIES to your PC without having to connect the tablet and then save the file firmware (this requires some tricks) and flash it via Odin. To do this, you need only enter the serial number and model type of the device in KIES menu Tools -> Firmware Upgrade and Initialisation. More details have here:

Can someone please help me

I was trying to update my phone and something most likely went wrong. Then the update installed and screwed up my phone. When I turned it on it stayed on the startup for so long. I tried to clear cache through the bootloader, but now it shows the android screen of death except it flashes. This occurs even outside the bootloader.
I am rooted with stock os.
Thanks in advance to whoever helps

Take the firmware from Asus website, for me I took UL-Z00A-WW-2.19.40.22-user.zip
Boot the phone in bootloader and try to go in the recovery screen, it took me a lot of tries to get in it!!!
From here you can select "insall update from ADB"
From your PC you do a "adb sideload UL-Z00A-WW-2.19.40.22-user.zip"

That's normal. When you get the error sign when booting into stock recovery, hold power down and press volume up and quickly release both buttons at the same time. If done correctly recovery menu will pop up and then you can start actually flashing.

does this still work if the screen is flashing, because I tried before and it did not work, maybe I pressed it wrong or there is some other issue.
Thanks

Question about tmobile G95TUVU3DOI1

Hi, I'm kinda new to rooting android phone.I just got a galaxy s6 edge from tmobile and I would lIke to root the phone. Searching around the forum but still doesn't ubderstand how's it work. So I got a galaxy s6 edge, baseband version G95TUVU3DOI1, come with 5.1.1 SMG 925T. Question is if I'm root the phone will i able to restore back to stock firmware, will tmobile able to find out if I rooted or not? Because I'm in Jump! Program and plan to switch new phone next year. And its there any easy step by step guide to root the phone. I don't really care about Samsung pay, would like to have fingerprint sensor if possible. Thank you

Before you do anything, understand that you WILL TRIP KNOX AND BREAK SAMSUNG PAY. Also, it is your choice to modify your device and this process seems to work differently for differnt people, so if anything happens, it's on you. However, there are several threads here that can help you if anything goes wrong

Wait for the little box at the top left to turn blue
On ODIN, click the AP button and locate the UniKernel v8 file that you downloaded before
Once you've found it, double click it to fill in the AP field with the file
Click START and do not touch anything until it's done.
Your phone will restart and once it comes back up, you'll be rooted. It can take several minutes for it to fully boot, so give it time.
Now, this is optional, but if you want a custom recovery to flash custom ROMS, download TWRP onto your computer from here: http://forum.xda-developers.com/tmo...recovery-twrp2-8-6-0-g925t-5-1-1-of6-t3143002
Flash that file through ODIN using the same process as you used to flash UniKernel.
This recovery will let flash custom ROMs. I recommend XstreStoLite as it is very good on battery life, but you will not be able to use WiFi calling or VOLTE. You can download it here: http://forum.xda-developers.com/gal...xtrestolite-deodexed-mod-edition-1-3-t3119968
Let me know how it goes.

Can I unroot in the future if I want to go back to stock?

Yes. You'll just have to download the latest firmware from here or Sammobile.com and flash it using ODIN

Thank you. One last question, any chance using Odin will brick the device?

Yes. There is a small chance, but the method I described is the exact same method I used on my device and I've had no issues. Even if you do, there is almost a 0% chance of a hard brick unless you touch something you're not supposed to touch, and if you do soft brick, there are a few threads here that should be able to help. More than likely flashing stock firmware will fix any problems you have.

thanks akw for the run through, I've been away from android for 4 months and ran back to it. just got this phone and wanna quickly root it.

i need help too. i am trying to use smart switch as my last resort but its not working(ish). after installing the factory firmware it says the device will restart, unplug and plug it again. on the phone it reset itself and then with the green android logo saying installing system then 1/3 of the loading bar it just says erasing then blacked out then back on bootloop. i can still boot to recovery mode and download mode.

Where are you getting the firmware from? What version of ODIN are you using? What port are you using in ODIN to flash the firmware?
There is a Mega download of the DOI1 firmware somewhere around here. I recommend downloading that and flashing using the AP port in ODIN 3.10.7, using the cable that came with your phone. This is the exact method I used to return to stock with no issues.
