First of all, sorry for my bad english!
Well, I started to look for some good custom roms for my galaxy s6. I was using the xtrestolite deodexed 2.4, and then I changed to Arrow Rom. Then, the developers of xtrestolite updated their rom to android 6.0
But now, idk why, when I try to flash any rom with twrp, I get no errors, but the phone doesn't boot up. Only with I install the stock rom with odin. I tried updating the modem to a android 6.0 version (the xtrestolite thread told me to do so), i dont know with this can help, I'm kinda new in this custom rom things.
So, summarizing, I can flash custom roms with twrp without errors, but the system get stuck at the logo, sometimes without the red alert (recovery not SEandroid enforcing). And then, at this point, I can only shut it down and go to twrp or download mode.
you need to follow the recommend steps exactly. upgrade both bootloader and modem for your device. Then do a date factory reset before flashing the rom.
these steps will install the proper files to avoid boot loops. the reset will make sure there are no strays files left.
The thread says to install the bootloader and modem for android 6.0, then install twrp, and then do a factory reset to flash the rom. But how do I flash the modem and bootloader? I know I have to flash the boot loader under the BL button on odin, and the modem under the CP button. But when I flash them, my phone automatically start to boot loop. And at this point, I can't enter twrp anymore, just download mode. I'm using currently the stock 5.1.1 rom for galaxy s6 (g920i) rooted with a custom kernel (unikernel v2 0008), and with the twrp recovery 3.0.0.1 . What are the steps to flash the custom rom? And why I need to flash boot loader and modem for this rom? I never had to do this to any other custom rom!
once you have flashed the bootloader and modem, you need to reflash twrp. as new bootloader and modem have broken the connectionfactory reset
After resestablishing twrp, boot into twrp and do a factory reset. Then install the ROM
The reason you need to do all this because 6.0.1 has been given a major redesign including touchwiz. The previous roms you have flashed only has been upgraded from 5.0.2.
Ok, so can I put them all together in odin, (bootloader in
BL, twrp in AP, and modem in CP), and then flash it? Or I have to flash them separately and uncheck the auto restart in odin? Because when I flash just the bootloader, it get boot loop when restarting.
Ok, once I flash just the boot loader via odin, and my phone restarts, I get stuck at the logo, not even a boot loop. Then, if I shut it down, i can't enter twrp, only download mode. Even if I flash TWRP again, I can't manage to enter it. So, at this point, I always have to flash the stock g920i rom with android 5.1.1, to turn it back on, and then flash TWRP.
Does someone know how to proceed?
you need to flash boot loader and modem together. make sure your phone is fully charged.
then flash twrp, then boot into recovery without starting the phone.
do a factory rest without flashing the rom. flashing bootloader modem and twrp should not be causing a bootloop.
then start the phone let it settle down and see if the 5.1.1. rom works with the upgraded bootloader, modem and twrp.
load the rom onto your hard drive, then reboot into twrp and install the rom.
try this the first time as a dirty install, if that does not work. I suggest you do a full erase and start from the very begining.
Thanks! I'll try this.. I'm kinda busy this week so I'll do it in the mext weekend! I tell you if I made it work the soon as possible.. thx for replying!
Sorry for taking so long to answer this post!
I want to ask you, if I flash the stock marshmallow rom in my galaxy s6 g920i, can I flash the XtreStoLite marshmallow rom, without flashing the bootloader and modem? Or I have to flash the marshmallow bootloader and modem for the custom rom anyways? Sorry for bad english
Ok so, I flashed the stock g920i marshmallow rom, and my modem and bootloader are EPC6 and EPC3. In the topic of the deodexed XtreStoLite custom rom, it says to download and flash the modem and bootloader for marshmallow 6.0.1, but I'm already running this version. BUT I have the EPC6 bootloader and in the topic, I can download the EPC7. Is it there any difference? Or can I flash the custom rom without flashing this EPC7 bootloader?
And, btw sorry for being such a noob, but can you explain me what are the bootloader and modem functions?
Thx for all!!
Hi,
I've been trying to upgrade the firmware. My phone is rooted and it keeps booting into twrp and I have no idea what zip to flash as nothing shows up.
The screenshot shows what I see before of automatically boots up.
Can anyone please help.
one of the first, and most basic rules of Android is that you can NOT be rooted and then upgrade your firmware with a factory firmware upgrade..this is how it works 99% of the time
You can flash original recovery.img from your firmware file via fastboot then upgrade your firmware via ota and finally flash twrp via fastboot again. Good luck
Thanks all. Sorry for a simply muckup on my end.

Just keep pressing Volume up + Power even if the phone boots once or twice.

Hi,
i encountered almost the same problem tryng to install twrp, so, when i try to come back to stock and relock the boot loader, i went to bootloop for some times. What i did:
donwload official stock b389, extract it, and flash manually (fastboot flash cust cust.img; recovery; boot; system)
failed, i got bootloop.
hardreset, not sure if it was acessible and i did it for sure...
download from official honor/hawei site, the 2 package to rollback from nougat to marshmallow.
installed the, again don't remember if it worked in dload like the official site teach you or if i did it manually (extraction, fastboot flash ecc ecc)
so, flash the mid packcage (from nougat to marshmallow) then flash the marshmallow firmware.
now, try to reset, and again, try to flash a stock marskmallow firmware.
the problems i encountered was (i suppose) it fail to manually flash a marshmallow firmware on a nougat bootloader, so, with the rollback package i was able to have a marshmallow bootloader where flash the stock firmware.
it took me time, sweat, and fear, but at the end it worked. It's easyer when you decide "i blowed it up, whatever it happens, i don't care..."
Hello, today while trying to get back to stock i wierdly bircked my honor 8
I flashed the stock recovery and stock boot img
Then i flashed a rollback package and a marshmallow package which i used for this same thing before.
Now the phone didnt start for a solid 30 minutes and ive decided to reflash the rollback and marshmallow package, but after i flashed the rollback got stuck at the boot logo, not even the stock bootanimation showing up.
The phone doesnt reboot neither in any of the recoveries nor in bootloader.
Any help would be appreciated.

It will be tricky if you haven't at least access to fastboot :/
I think the best thing to do is to flash another ROM, use the dload method again and again because apparently that's all you have
You can also take a look at DC unlocker, it may resolve your issue
Have you managed to fix the phone ?
Not yet, i will try again tho in a few hours with the dload method, by flashing stock boot img then using rollback and then marshmallow firmware.
Don't forget that you need a stock BOOT.IMG and Recovery.img to perform dload method

Okay so after all of this i managed to reboot to bootloader and get my hands on one of my previous unlock codes. So now ive got an unlocked bootoader, but after fashing twrp the phone is stuck at the 'your device is booting now' when im trying to get in it
I thing you have flashed the wrong TWRP, check for the latest version or at least the one for your build
uh well, hello there again.
i've tried to do the dload method which failed(i used lots of versions tho none worked)
and i've tried flashing marshmallow twrp, which at the moment, well, it cannot mount anything. no partition can get mounted.
Does any of you guys have an idea of what i could try?
thanks in advance
Does it mean that you have access to TWRP ? if TWRP cannot mount a partition, go into mount section, tick system, data, boot, vendor and then reboot to TWRP again. Then try your previous operation. If it cannot mount data, go into wipe, advanced wipe, and click on format data, then restart TWRP and try again
seems like i somehow broke the partition table, cause it shows every storage as 0 mb and mounting isn't available, cant tick the option. Looks like i will have to find some service center to repair it by my own cost, by the end of the month. Though im giving it around the 25th so i got some more time till then, so maybe i find some solution to this problem.
Hey, so I managed to make the phone work again.
I have flashed boot cust recovery recovery2 and system from the italian marshmallow firmware, then I flashed that same firmware using dload method(tho it failed at 99%)

You tried only once? Maybe you should now try to flash TWRP recovery and restore a backup made by TWRP. I can provide you one but for FRD-L09, not another. Another method would be to flash the rollback package and then retry flashing an EMUI 4.X ROM (dload method for both), hope you'll figure it out
I think i expressed myself wrong.
That was how i got the phone to work.
Oh lol I misunderstood because of the "it failed at 99%" and I thought the phone wasn't rebooting , no matter I'm glad you succeeded
