[Resolved] Stuck in Download Mode after failed flash attempt.

Okay, so I finally decided to ditch AT&T and go full Paranoid (This is not my first flashing attempt with Android devices). Got the latest version, etc. Load into BootStrap and wipe everything. Go to install PA and for some reason I had neglected to tell my build.prop (ro.product.device/name) is supposed to be "jactivelteatt"/"jactivelteuc" and not "SN-M9009". So when I started the flash process, immediate error and now I'm stuck with a phone with no OS or bootloader and can not, for the life of me, find a ROM to flash with .MD5 or .TAR that will work with ODIN. I did find "Oneclick_I537UCUAMF1" that gets all the way to the end and fails. Tried multiple times with multiple cables.
Please if anyone has any idea's, please help.

Oh god are you on the US version (SGH-I537)? If you're on the international version (I9295) ignore this post but otherwise, you need to read and take in my short rant. Trust me I wish this weren't the case, but it is, and it's important:
The Galaxy S4 Active i537 has a locked bootloader. There is no way around this, no ifs ands or buts. You simply cannot flash custom ROMs or recoveries. That's it, end of story as far as CM, CWM, AOSP and such things are concerned. That being said there is a sort of recovery called SafeStrap which you can use to make nandroid backups, flash mods and STOCK-BASED roms, but it's not a true custom recovery in the sense that we had been used to, because of this locked bootloader nightmare.
OK so I think you're gonna want to check out this thread. It's all about how to install any firmware from download mode, I think you're gonna have to go with NE3 or NH3.
Let me reiterate. NO CUSTOM ROMS. NO CWM. No Paranoid, no cyanogenmod, no AOSP, no crossing go before going directly to jail. Sorry for the stupid joke but seriously, you have got to keep your phone on stock-based roms (of which there are unfortunately few).

You need to make sure you are flashing a version that is the same or more recent than the version you are currently on. You cannot downgrade your firmware or else you'll end up with a bootloop.

PLEASE HELP ATT note 3 e:unable to mount system

Hi
I have ATT galaxy note 3 first time I installed a rom I did it over the stock rom slot, no biggie, to make a long story short last rom I had was alliance last version, didn’t work for me, so I decided to install (FireNoteDeodexV20XGrandFinale)
So I booted into Safestrap 3.75(TWRP v2.7.1.0) by simply restarting my device and got that recovery or continue buttons.
So I did a factory wipe but I also did an advance wipe and checked (system).
After that I went to install and selected the above ROM zip and installed it and after I hit continue at the safestrap screen where it also says disabled it always has. It stays blank.
So I booted up to SS again and now whenever I select factory wipe or system wipe or try to mount I get the same message E:Unable to mount ‘/system’ and E:Unable to mount ‘/systemorig’
And now im stuck with no phone and cant install any ROM
Theres a lot of threads about this but please oh please masters bare with me I just need step by step, what should I do and what files do I need to download.
Your help is highly appreciated.

Are you on Jellybean or Kitkat..this should be in Q&A section. But we will try to get you going

If you have a computer. And a sdcard slot on it download and install a kitkat rom of your choice from the att note 3 rom section. Because you most likely are on the newest bootloader you can't flash jb roms. You have to stick to kitkat roms.

Didnt work tried and it failed.

You should look in the general section for att note 3 and find the Odin files for kitkat and Odin restore your phone. Then start over rooting and installing a custom rom. Probably your best bet.

Note 4 SM-N910T that keeps getting stuck in a boot loop

So i purchased a Note 4 SM-N910T about a year ago. It worked fine but last month shortly after the 5.1.1 update I did it started randomly restarting for no reason. First i taught it was Snapchat because I red somewhere that there are camera problems, so I stopped using it. But it kept restarting even after that. From then I have made a factory and a master reset, rooted the phone and even installed CM 12. No mater what i do it keeps on restarting. The only way to get it out of the boot loop is to connect it to a charger that is not a fast charger. Then it starts charging and works normally and you can do everything normally. After you remove it from the charger it works as long as you do not use it. When you start using it and want to do something with it it starts restarting again. I hope somebody can help me fix this issue. I have noticed that connecting it to WIFI makes it 100% sure that it will restart any moment. If you leave it without WIFI as long as you do not do anything big it will not restart. For example I watched series on my phone I downloaded beforehand. I was able to go to the CM 12 file manager and change series for the duration of my bus drive and it has not reset yet and it has not been connected to a charger for around 12 hours already.
My last resort is to wait 3 hours for the stupid free 5.0.1 official firmware and flash it using the TWRP Recovery or Odin. If that does not work I would have t give it to a service. Any help will be greatly appreciated! Also a link to where I can download the 5.0.1 official firmware for free in normal speed will be of greatly appreciated as well!
Merry Christmas!

That's odd, I recommend odin flashing the stock ROM and everything. (Modem + bootloader) the latest one is DOK2 for T-Mobile

To revive the thread I tried flashing the N910TUVU2DOK2_N910TTMB2DOK2_N910TUVU2DOK2_HOME.tar via Odin. It all went fine and after starting the phone it went on to the step where its optimizing apps. It got stuck there and it went back to the boot loop. I had reflash the CM 12 and TWRP Recovery and now I am back at 0. So my question is how should I flash the stock rom. Go to TWRP do a factory reset than turn the phone off and flash the stock rom via Odin? Should I also flash TWRP ans SuperSu after flashing the stock rom?
Thank you for your help!

I've been having the same problem for about a week and a half; it's super annoying. I was running Dynamic Pop on COG2 then yesterday I updated to DOK2 and flashed Maximum Overdrive... no improvement. It rarely even fully boots before freezing or rebooting.
My best guess as to what the problem is that it may be overheating because it tends to actually boot if I put it in the freezer while booting, but then it freezes soon after taking it out. I suppose it could also be internal memory corruption.
Either way, I'm getting ready to do a warranty exchange.

First focus on getting a clean stock firmware booted. Do what you mentioned above but don't flash TWRP or superSu until the stock ROM is stable. We need to narrow down the issues so do as few modifications as possible.

I actually downloaded 2 stock roms for my Note 4. One was the COG2 and the other one was the completely stock firmware. I tried flashing them but Odin failed (Auth) whatever that means. The only stock rom I was able to flash was 5.1.1 but it wouldn't boot up so I had to install CM 12 again! I have no idea how to fix the phone. All I want is to return to 5.0.1 and delete any changes. The phone has no apps on it so i have nothing to loose but I do not know how to do it..

You cannot use 5.0.1 ROMs on DOK2 they will never boot and no down grading. You have to use 5.1.1 ROMs for now on.

Epg2 firmware

Anybody get it yet? Supposedly went official yesterday. About 300MB.
I unlocked your mum's bootloader.

It just arrived, and it was about 300MB. IT rebooted into TWRP, which just sat there. I rebooted, and then Andorid complained that the update didn't work. Well, duh!
That said, now I would like to know what I should have done or should do in the future. Any thoughts?

Mine just arrived
What's new?

Just found a story about it here - it is indeed the July update:
http://www.tmonews.com/2016/08/t-mobile-galaxy-note-4-note-edge-july-security-update/
Links in that article will eventually point you to here, where the update can be downloaded manually and installed via Samsung Smart Switch.
https://support.t-mobile.com/docs/DOC-16486#update_download
Since I am rooted I am actually not sure what to do, and would appreciate some advice.

300 mb is a big update. If you are rooted you will need to flash the new firmware in Odin. But you may want to hold off. I am note sure it adds any new features and will probably make your device incompatible with any ROMs that are currently available.

Thanks - sound advice.
So, where should I be looking on my Note 4 for the 300 MB download that happened earlier this morning, so I can delete it or copy/move it off for later?

I just got it but waiting to see if there are any bugs or negative effects. I'm not rooted so there's no way to go back.
Sent from my SM-N910T3 using Tapatalk

Still looking and haven't found any clues for changelog, not even security update. Anybody?
I unlocked your mum's bootloader.

Yep...trying to figure out how to avoid the update too.
I'm stick rooted with XPosed, Beastmode kernel, and a few other mods.

I just did the update, and I can confirm that TWRP, root, and xposed all work.
I don't know about compatibility with custom roms though.

Yeah, if you can't find the update. You can just install the latest firmware you can find with odin, then update from settings.

Hi Folks,
I have no idea what "update from settings" means. Also, no idea where to start looking for the update - heck, I don't even know what to Google to find it. Thoughts?

From your device click settings look for about device click then at the top you will see (download updates manually) If you are rooted or removed any system apps dont go that route, the update will fail.. You then would just need the update file to flash with odin.. Might look in overdrives op.

I believe this is the AFH Linky for the new firmware also fwiw: https://www.androidfilehost.com/?fid=24588212152306227

So just to be clear, Overdrive is a MM-based T-Mobile ROM, basically just debloated and with some minor tweaks.
As a convenience, he has linked to "N910T Stock Odin Full EPG2 Firmware File," which we can flash using TWRP onto an otherwise stock+rooted MM 6.0.1.
I got this right?

-5.1 stock android : BLU_V0030UU_V07_GENERIC 25-01-2016
- 3.10.65+ kernel
- Rooted with kingoroot
- Previously had xposed, but uninstalled due to random reboots.

Unfortunately most custom ROMs in this forum were based off Gionee so likely you will get no SIM. Use your stock ROM /etc/firmware folder to replace that in ROM.

Thank you for your response.
I've already got twrp installed for 5.1
So i should just install this MM based ROM i said on the post and replace /etc/firmware folder?
Or i need to install stock MM from ota first?
Thing is, i cant OTA update, it says that the system is corrupted, i even tried from twrp but no luck

I've seen that i need stock mm to be able to install most of the custom rom's in xda
Thing is i can't install any OTA update. Should i flash 5.1 stock rom on top of the modified one i'm running?
By modified i am talking about the root and xposed, which is the cause i cant OTA

Follow my steps exactly then you can do OTA to MM.
The key is to use the 8 files backup to restore stock 5.1, not the backup only includes 4 files.

Alright, ill do that. Tried with the 4 files backup last night, didn't work as you just told.
Do you have a link to the 5.1 stock recovery i should flash with sp flash tool? I can't find it anywhere. It wont work if i still have twrp installed, right?
Thanks! i really appreciate it, and great guide btw

I installed the 11 files backup and i still can't get ota. I should install the stock recovery, right? got a link for that?
Thank you in advance!

In my case I have a fully working STOCK but ROOTED Marshmallow Blu Vivo XL with working IMEI, but as soon as I wipe and install say AEX rom, I lose both IMEI functions and also get the dreaded wifi NVRAM error (but working wifi).
I also restored the etc/firmware directory to AEX but it wont help regain IMEI functionality.
MTK Engineering mode does not work on AEX because it complains not being stock rom so it closes.
For the life of me, I can't make a connection to the PC through SP Flash Tool too.
Any pointers?
TIA!

Thanks for the reply Min1968!
Yes, I know how to recover IMEI on the stock ROM and I'm currently running stock MM rooted with working IMEI.
The problem I have is that I can't run custom ROMs even if I try the etc/firmware trick you mentioned.
What is the stock TWRP partition that has the modem and IMEI? Maybe if I flash it back through TWRP once I get AEX rom up and running?
Thanks!

Okay, i fixed it reformatting the data partition on twrp. Thing is, when i want to install the recovery that happens. Maybe if i dont oem unlock?

well, i did that and it booted with the stock recovery. But i still can't OTA, i really dont know why, i even could not when i bought the phone

Hey guys,
I am trying to intall a custom rom on my blu vivo xl. My worries are that i either soft-brick the phone or boot the new rom and having no signal due to no imei, or no 4G due to band change if it's even possible. I'll leave you with some reliable data:
-arch64 procesor
-5.1 stock android : BLU_V0030UU_V07_GENERIC 25-01-2016
- 3.10.65+ kernel
- Rooted with kingoroot
- Previously had xposed, but uninstalled due to random reboots.
