flash without pc - Galaxy S6 Q&A, Help & Troubleshooting

Is it possible to flash bootloader, modem and twrp without a PC? My S6 doesn't communicate with any pc anymore. I did everything but it doesn't helped. So is there a way to do this?

If you are rooted yes. You can flash Twrp and modem through recovery, I'm not sure about the bootloader.
But if you are not rooted there is no way.

I am rooted. But is there a way to update to mm without bootloader? I don't think so. Looks like I am stuck with 5.1.1

Can I flash a rom?

Just got a verizon s3. It seems to be rooted and is on CleanRom 8.1 on android 4.3. It has the baseman i535VRBMB1.
Can I flash a rom that says I need ML1? Is it safe or do I have to install ML1 first? And is the phone unlocked?

If it's already rooted and has a custom ROM, I assume so. Have you tried booting into CWM?
Nope, haven't tried. Im sure it has a custom recovery. This is the rom I want to install:http://forum.xda-developers.com/showthread.php?t=2608639
What should i do? How do I install ML1? (do I even need it? or can i flash the rom as is?)
Try booting into recovery mode (hold Home Vol Up and Power), and see if it's stock or CWM. If it's CWM, it should be very easy to install that ROM.

Bricked Recovery

Greetings,
I recently rooted my Verizon 4.4.2 S3 using TowelRoot. (SCH-I535) Afterward I attempted to flash TWRP using ODIN. I kept getting an error message when flashing. I think tried TWRP Manager. I selected the proper IMG and flashed. It said flash successful. When I enter recovery I receive a LARGE yellow caution triangle with the message, "System Software not Authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest VW store for help."
I attempted to flash the factory recovery (Verizon-SCH-I535-StockRecovery.tar) using ODIN. It says the flash is successful but I still receive the same error message. My flash counter is at zero. Any idea how I can either get my factory Recovery back or get a functional recovery?
Thanks so much!
The bootloader is locked on 4.4.2 which makes having a custom recovery impossible. Try to flash the full NE1 image in ODIN. Here's the link:

Thanks. I ended up using the Verizon repair tool which actually did a pretty good job. It put 4.4.2 back on unfortunetly. After that it was Towel Root then TiBu restore. So is safe strap the only way around the locked bootloader? Can I JTAG?

Yes safestrap is the only way around. Unfortunately you can only flash NE1 based ROMs via safestrap and there aren't any custom ones out yet that I know of. I believe the devs need kernel source released before whipping up some updated ROMs with the new base.
Regarding JTAG the guys at mobiletechvideos apparently found a way to downgrade the s3 to the 4.1.2 firmware which would allow you to unlock your bootloader again. I have not heard of anyone on here that has tried that service, though.

Bricked the S6 SM-920I. I'm at wits' end.

I got the Galaxy S6 yesterday and coming from Nexus 5, I wanted to remove the existing bloatware by flashing the XtrestoLite Deodexed ROM. This one here: http://forum.xda-developers.com/galaxy-s6/samsung-galaxy-s-6--s-6-edge-unified-development/rom-xtrestolite-deodexed-mod-edition-1-3-t3119968
I'm haven't had much experience in rooting and it's my first time flashing a custom ROM. The phone was running on Android 5.1.1.
Apparently I failed. I started with CF-Root but I wasn't sure if it was done correctly. This was followed by TWRP 2.8.7.1 . Then I tried booting up the phone and the boot logo just loops. I tried to wipe the cache as well as the Delvik-cache through TWRP but it's still the same. Then I tried to flash the stock ROM that I found online but I got the error "Nand Write Start" followed by "Fail". I seem to have tried everything and now I just want to get the phone to work again. It shouldn't be so hard.
Someone help me please :crying:
Have you tried to flash the stock rom via Smart Switch software? There's an option in the top of the window where it says "More" called Emergency Recovery. When my S6 bricked nothing but that did the trick, you should give it a try.

How did you do it? I've installed the Smart Switch software but the device doesn't appear under the list in emergency software recovery, so I can't proceed.
Edit: I managed to do it through initialization. I'll update when it's done.
Edit 2: It worked! Thanks so much!

Your PC is recognizing your phone? If not maybe you shall update your drivers first. My S6 is the same model number as yours and it does appears in the Emergency Recovery list.
Another solution could be trying to flash using another version of Odin; I saw a similar problem on another forum and it was solved using Odin 3.10 to reflash the stock firmware.
Also remember that you can't downgrade your firmware once that you are on 5.1.1, no 5.02 or so allowed.

By the sounds of it you're able to boot into twrp? If so then simply boot into twrp, connect to your computer and copy a flashable rom to your phone and install it using twrp instead of odin

How could I transfer the flashable ROM to the phone when I can't have it boot up to connect to my computer?

Since you're using the same model as mine, what are you running on your S6 right now? Are you able to root and flash a custom ROM like XtrestroLite onto Android 5.1.1?
Can you guys help me check if this post has the correct steps or is it missing anything like bootloader and root?

Actually yeah. Earlier tonight I flashed XtreStoLite over stock 5.1.1, but I must confess it wasn't as easy as I thought, mainly because I didn't followed the steps in the right way and I ended up having to root my phone through installing UniKernel, which is pre-rooted and that did the trick for me, because I got stuck in the Samsung logo right after I tried to flash with CF-AutoRoot, needless to say I obviously couldn't root with that method and had to reflash stock 5.1.1 firmware to unbrick my phone, install UniKernel, and after that I was able to enter my phone config, uncheck the reactivation block under Find My Mobile settings (which was the reason for me to get stuck at the S-logo) and then flash through Odin XtreStoLite deodexed and Xposed FW too, so I can tell you for sure that SM-G920I can run XSL like a charm.

1. So what is the correct order?
2. Did you have to manually unlock bootloader?
3. And is it a must to install uniKernel in order to root the device?
I have no idea how to proceed now.
This requires a lot more effort than I thought :fingers-crossed:
1. The correct order apparently WAS to flash 5.1.1 bootloader and modem over 5.0.2, then root, then TWRP, then flash XtreStoLite, or at least that was what I understood from Edgar's guide (as you can tell, I hurried myself too much and was to excited to flash XLS, so I didn't read properly).
Since I (and I think you did too) installed stock 5.1.1 first, there was no way to autoroot nor ping-pong root the device, that was the reason I got stuck in the Samsung logo screen after trying to autoroot, so I had to reflash stock 5.1.1 to regain access to the device settings/Find My Mobile as I explained before, after that I flashed UniKernel and that did the trick, no other steps were required to achieve root access beyond this point.
2. I didn't had to, but your carrier may have locked yours. My device is a SM-G920I (as yours) from Telcel carrier, so I can tell for sure.
3. There are several others way to root devices running over 5.0.2, but according to my personal research there aren't much options on 5.1.1 other than flash a pre-rooted kernel, but UniKernel isn't the only pre-rooted kernel, so you can choose whichever you like the most.
If I were you the first thing I'd try, as I said earlier, would be to switch to another Odin version or another firmware (as long as it is 5.1.1) and if that don't do the trick, then I'd update drivers and try via Smart Switch again.

What did you use to root? May I ask for the link? I just tried flashing CF AutoRoot and now I think it's bricked again. (RECOVERY IS NOT SEANDROID ENFORCING) I'm thinking it might be due to incompatibility because I got it from here (https://autoroot.chainfire.eu/#odin) and the Android version states 5.0.2.

Yep, that was the exact moment where mine got stuck too, as I stated before at that time I had to reflash stock firmware. The trouble is caused by CF-Autoroot, it won't work at all when you're on 5.1.1 (at least with SM-G920I) and if you try to root using this method, you'll get stuck with the message "RECOVERY IS NOT SEANDROID ENFORCING". You'll have to reflash to stock too, I'm affraid...
Flash UniKernel via Odin once you're on 5.1.1 stock again and see the magic happen. Once you have root access, gained by this kernel, you can install TWRP and flash XtreStoLite or any other rom you may want. Here is the direct link to the post: http://forum.xda-developers.com/galaxy-s6/samsung-galaxy-s-6--s-6-edge-unified-development/kernel-stockmod-kernel-t3100395
Hope you get lucky.

I just did that before you suggested it and it worked! I was so elated! I love you bro (no homo). Our situations are identical. Now I have XtrestroLite running on the S6! Thank you so much!
Simply put:
1. Update bootloader and modem
2. Install TWRP without root via Odin
3. Install UniKernel via TWRP
4. Install ROMs!

Can't update my Verizon Note pro to lollipop

So, I have the p905v and I rooted it with towelroot, and it was completely fine. I then tried putting twrp recovery on it through flashify the wrong way and now I don't have a recovery mode. I can't update my tablet or factory reset it and I'm not too ambitious to flash the update into the device, is there a way to fix the recovery mode?
Grab the stock firmware from the link below and flash via ODIN from your PC. Make sure you download the right version.

OK, thanks! Another quick question, what if it goes through a bootloop and I need to factory reset it? Would flashing it restore recovery? And, you mean flash lollipop 5.1.1, right?
