In some countries if you fix this successfully, you can go to jail, you know.
I might get banned for this, but if your device IS a N9005, go search around for "QPST". And even if you find what works, your phone most probably will always be set to "roaming", so your contract better has good rates. xD

When you flash gng1 firmware PHONE BOOTLOADER UPDATE and PHONE EFS CLEAR in odin must be checked !!! Phone efs is automaticaly recreated by android !!! after that Wipe data and factory reset only if you still not have your imei back but it must be there !!!
Same steps if you flash android 5(bl,ap,cp,csc)

That's the problem, as this is exactly what you'll have to do. xD As far as I've heard, only QPST can do the trick only on (obviously) Qualcomm powered devices.
Else, you've got a small tablet. xD

[HELP] G900V-CID11 Toshiba-locked bootloader, looking for 6.0.1 ROM working

Hi all, I can't really figure out from all the releases posted here how to find a rom which can be installed on my phone, while I'm waiting for an unclock for CID11.
I've a 900V CD11 locked with BT1 rom sim-locked and SD-not working and now I can't use my phone at all. I'm in stuck at all.
I've rooted it already, waiting for a proper rom.
I tried some roms but I always failed, the last one "G900V_PF4_Stock_Deodexed_Debloated_ROM" which is made for locked phone, was failed to upload from chainfire.flash_0.50 in the middle of flashing.. it reboots phone and it become bricked
You may kindly indicate me the steps I've to follow to install the right rom, if I've to use safestrap or chainfire.flash_0.50.apk, and if I've to flash with Odin the bootloader and with which file.
Thank you so much, please add any consideration that you can consider important!

with the G900V, you dont want to try to unlock the bootloader or itll hard brick. You have to use safestrap
---------- Post added at 12:56 PM ---------- Previous post was at 12:54 PM ----------
if you go to sammobile.com, you can get the stock image to flash in odin to unbrick if its just softbricked. You may want to check the G900V forums to make sure that you dont flash a version that doesnt have root available for it, as vzw has locked the device down like fort knox. Im at work currently, but can look further into this for you after 6pm cst

I tried to unlock and it didn't hard brick.
I can use safestrap but to upload what? I can't unlock it (it's CID11), and I can't find a ROM valid for this phone! (the one I used (suggested on the root phone procedure) is SIM-locked and with SD not working).
I hope someone can suggest me a rom which will work on my phone. Thank you

also, i dont know what you mean by "toshiba-locked bootloader"

Wow you're in the wrong area... Go here and scroll down to prepare your phone for root
http://forum.xda-developers.com/showthread.php?p=64744405
Actually read everything and make sure you understand it before doing it because if you tried to unlock your bootloader when you have the wrong emmc (11 instead of 15) you either didn't read or or didn't understand the thread good luck and you should stick with the vzw specific threads with the 11 good luck and happy flashing

thank u for help! Are u addicted to that forum? I would really appreciate if u give me some help finding an uploadable version. I'm looking for a 6.0.1 with sim unlocked, root if possible and SD working. If there isn't exist one a LL could be good too, my phone is sim-locked now and isn't reading SD, so I can't use it.
Yes I rooted it, I can use safestrap and chainfire flash application (superSU installed). Thank you so much!

I've found the ROM, now I'm on 6.0.1 but without SD usage, looking for a fix..

Does it happen anyone that after BP1 flashing the SD card is not more available? Have you ever lost SD card with wrong ROM?
I don't know if it is electric problem or software

When you tried to unlock your bootloader it wiped it so you will need to reformat it for it to work again... If you would have read the thread you would know this?

So, does it not boot at all now?

Tes it works good, the only problem is that it can't read SD.
Yes I formatted it FAT32 already and other pone and PC works with it without problems.
When it was ROM G900FXXU1BOC7 it worked, after update to PB1 it didn't, is that possible that ROM prevent see SD?
Thank you

i believe @bad bone is correct, it sounds like the problem is the bootloader. You may have to flash a pit file in Odin to correct this. im basically bowing out on this because where your problem is may also lie a den of dragons. Im just hoping that a bump in this thread will get the attention of someone more familiar with this variant of the device. Also, locked bootloaders are the bane of Samsung using existence

I have the same device as you, I am on stock Android 5.0 rooted (CID 11), what ROM are you using for 6.0.1? Is your device still rooted? Can you point me to a helpful tutorial?

Rooted s5 MOAR rom
I have a Verizon s5, rooted it with a method on here by jrkruse I believe, flashed the stock debloated rom, have safestrap and su and busy box installed, then flashed MOAR rom for 5.0, I have CID 11, running pb1.

I dont own that device, but i thing this would work:
Flash latest 6.0 firmware with samsung smart swich (PC), enable oem unlock in settings, flash twrp for 6.0 with latest odin, do a factory reset and a full wipe (except external sd an android secure). Then download latest 5.1 firmware for your device an flash it with odin (it will take some time).

You are stuck on Marshmallow

Hai bro,,,
u try this one after flashing offical firmware simply reboot your device into recovery mode by pressing Power + Home + Volume UP and do a wipe data/factory reset, and wipe cache partitions then reboot your device, it will start properly and all problems are now solved,,,,,

With the J500H, Samsung decided to lock the bootloader, meaning you can't downgrade. J500h seems to be the only locked device. Unless someone finds a way to unlock the bootloader then you are stuck on 6.0.1.

There is no solution.

update: after spending days of searching from google, i found a 5.1.1 firmware that is compatible with my 6.0.1 firmware since they have nearly similar baseband versions(J500HXWU1APE5 for the lolipop and J500HXWU1BPG1 for marshmallow). so now i can upgrade and downgrade the phone's firmware with ease

please, help me.

u can show me. how to flash with odin (

Firmware downgrade Samsung J500H from MarshMallow with the second loader to LP.
Those who are faced with the inability to roll back to version 5.1.1 are uncomfortable with using their phone.
We need to either use the Philippine firmware or install a custom firmware Belousova.
I found an acceptable way to flash my phone with a stock firmware.
For rollback, we need a four-file stock firmware J500HXXU1APA5 or J500HXXS1APE1.
File BL with the second loader BL_J500HXXU1APA5_CL958143_QB8363487_REV00_user_low_ship_MULTI_CERT.tar or BL_J500HXXS1APE1_CL1011281_QB9453563_REV00_user_low_ship_MULTI_CERT.tar .
Odin.exe.
Please note: these files for the regions: CAC, CAU, SEK, SER, SKZ.
In other regions, wi-fi or a radio module may not work.
For other regions, you need another file for a specific firmware.
If you need another region, write me the name of your firmware.
The process of the firmware I will not describe, it is well known.

i just flashed a stock LP firmware that has the same region on my stock MM firmware(MBC) and everything worked fine
idk abt the others who updated on samsung updates(which locks the bootloader), since i updated it manually through odin in the first place

also this is my used firmwares:
5.1.1: https://samsung-firmware.org/download/Galaxy__J5__/zvs5/MBC/J500HXWU1APE5/J500HMBC1APE5/
6.0.1: https://samsung-firmware.org/download/Galaxy__J5__/4u11/MBC/J500HXWU1BPG1/J500HMBC1BPG1/

First update to MM have the some botloader like LP. But next update have other bootloader and you can't boot LP with odin to your telephon.
10:32 And some more - Philippines firmware LP 5.1.1 have second bootloader. You can downgrade from last update MM to LP 5.1.1 very easy.

I found how I can help for you.
You may download firmware from here :"goo.gl/Yk1Byz" and unzip and flash in odin this firmware.
Then if some hardware not working you may download firmware for your region from here:"goo.gl/SdcwhA"
and unzip repeat the flash with odin but with one file firmware.
And If you don't update your telephon to MM you can flash telephon using only this stock firmware. Save it. First file you can delete.
I am sorry - in first step you may set BL for APE1 file from my blog . It have second bootloader for firmware.

J500f (TGY) NO MARSHMALLOW Update

Hi guys my phone j500f (TGY) modele has no update to 6.0.1 .
So my qiestion is how to change csc to (INS) to get marshmallow update.
I already tried flashing another multi csc rom with odin, if failed with : Fail! ( Size!)
Thank you.

Flashing firmware from different region/carrier via Odin should work as long as its the same model which is SM-J500F. There's no need to change your csc. You can choose firmware from any region/carrier from this link: http://updato.com/firmware-archive-select-model?q=SM-J500F&rpp=15&order=date&dir=desc&exact=1
---------- Post added at 11:50 AM ---------- Previous post was at 11:27 AM ----------
If none of the firmwares worked, it could be that your bootloader is locked or it doesn't support marshmallow since there's no marshmallow update for your region.

As I said before, it could be that Samsung (or your carrier) decided to lock the bootloader for your region to prevent you to upgrade to marshmallow, I'm not sure why they did that tho. Just like what they did to J500H, they locked the bootloader for marshmallow so anyone who upgraded their device to marshmallow cannot downgrade again to lollipop anymore.

i have a solution.If you want to flash twrp into your samsung j7 runnign android 8.1.0 you need to wait the rmm lock to disabled automatically.If your rmm lock status is prenormal it means your phone is still locked by rmm lock.But if you don't see any rmm lock in download mode it means your phone's rmm lock is deactivated and you can flash twrp:angel:

But sir how it can be ?
I mean give me a solution for disable RMM prenormal status plz

For those who have trouble flashing custom binaries like TWRP because of "RMM-Prenormal", just use Odin Prince Comsy version

If that link won't work, go search for it.
