[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?

if you know the exact firmware number, you can find it with this tool:
https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146
i found mine with it, its pretty awesome, somehow scans huaweis entire database.
havnt tried the rom yet though. and you need your EXACT firmware number, if you could boot into os thats under settings and about phone, if you are bricked/ boot loop however, i dont know, maybe theres an adb command to find it?
sorry, im not much help.
pretty stuck myself.. heres my original post if anyone can help me:
https://forum.xda-developers.com/android/help/help-twrp-backups-t3726542/post74989641#post74989641
good luck man, hopefully that firmware finder tool can help you find your stock rom

Translated with Google and download factory image for your phone and flash it with sp flash tools.
regarding root
I've heard good things about Magisk for rooting
but whatever you do, I do not recommend using supersu.com(an impostor site) as that's what broke my phone...anyway, only downoad root and other system stuff from xda, or linked to from xda...if you want traditional root you can try the supersu from xda, but make backups beforehand, you need a custom recovery for it anyway...
romanian rom = unbrick
thanks for the link, the romanian rom seems fine...
no idea why there are country-based roms though, what's the difference?
the phone won't run at all to do this please please please help

I have made custom roms for huawei y3 ii lua-l21

my moto g4 plus has unknown baseband version and it cannot be recovered by flashing

my moto has unknown baseband version .i tried hard reset,tried different stock roms but the problem still exist.IMEI invalid and also network and wifi ndoesnt work can anyone help...
What device do you have and which territory are you based in? You may have corrupted your hw or modem partitions by flashing firmware, which may be a cause of the loss of IMEI and radios.
There's a way to copy uncorrupted partitions from a working device to yours, it however needs partitions from the same variant as yours and you'll need an unlocked bootloader (not sure if you need TWRP or it's possible with stock recovery, someone else familiar with pushing partitions onto Android via adb can perhaps answer this?)

Samsung S5 (SM-G900F) stopped loading

Hi,
My gf's phone stopped loading yesterday (stuck at the SAMSUNG logo), so I've tried to factory-reset it via recovery menu. Unfortunately, this didn't help, so I've decided that I need to re-flash the system. After some search I found https://www.kingoapp.com/root-tutorials/how-to-flash-samsung-stock-rom-via-odin.htm and tried to follow it. After checking the sticker behind the battery, I've learned that the model is SM-G900F. Unfortunately I wasn't sure what ROM was installed on the phone before and couldn't find any Ukrainian ROM, which is where the phone was bought originally. In the end, I decided to try installing latest ROM for Germany O2, since this is the operator that my gf uses now.
Unfortunately, Odin refused installing that image with an error "FAIL! (Auth)". After some further searching, I've noticed that when the phone is in download mode, it shows model name SM-G900V. I have no idea why and the ROM that was there before was clearly non-Verizon. Still, having no other option, I've downloaded Verizon ROM and it installed successfully. Luckily the phone has booted, but as expected, it wouldn't connect to any other network than Verizon, which is kinda useless to me given that we live in Germany and use O2. Now I wonder if it's possible to somehow root the phone, install custom recovery and flash that German O2 ROM?
The device is running Android 6.0.1 and kernel 3.4.0. How do I root it? How do I install custom recovery? Which one would you recommend?
Thanks,
Sergiy
In order to root it and install custom recovery you need to follow this guide

After rooting and custom recovery installation you need to decide what ROM you want on this phone ,you can install any ROM that supports sm g900f or g900v or klte (that's your device nickname)
I am on aex and it works good for me so you can try it https://forum.xda-developers.com/galaxy-s5/unified-development/rom-aospextended-rom-v5-4-t3779910

Follow the installation instructions from the Aex link and you should be good to go
If you need google apps and play store install gapps zip the link for that is also in the aex post hope it all works out for you ,if you need any help just ask

Seems, you can read russian.
You may like to follow this my guide to flash SM-G900V with an international 6.0.1 ROM.
I think, you can even use VIA (O2) CSC.
P.S. Please, pay attention to:
1. The first boot after factory reset may take 12-15 min (but not more than 20), so be patient. This was the problem, I guess.
2. Read the QA section in my guide to find the answers to your questions about root and custom recovery. And feel free to ask questions (here or there).

Thanks a lot. Indeed, I have probably not waited long enough for the first boot. The instructions you linked, worked! My gf is happy to have her phone back.

Радий був допомогти.
And note for the next time: it's a good idea to try clearing cache and safe boot before performing a factory reset
