I have the same problem.. on my case, i upgraded my 6.0 with official 6.1 using official updater.. i managed to do it successfully.. but i repeated the same thing.. i used the official updater again.. then currently stucked on the samsung boot logo only.. tried mirage and other.. no success :(
[Upgrading, Modifying and Unlocking] homedog:
i fixed my.... i search in romania (bucharest) someone with jtag box... after a full day he fixed my phone ... cost me around 30euro.. i tried and other phone service but they whare unable to fix it... just with jtag box
[Upgrading, Modifying and Unlocking] emjaygee:
man, what is this jtag box? please enlighten me.. thank you very much.
[Upgrading, Modifying and Unlocking] homedog:

my phone was dead, as i said, no service man cant unbrick, i find a guy in bucharest with riff jtag box, he weld some cables on i780 motherboard and start and upload the boot, was hard, around 8 hours. I think u gonna find a riff box at a more specialized service ... sorry about my english ... good luck. (dont try anymore, if boot is broken, just a riff box can make the phone get a new life)
[Upgrading, Modifying and Unlocking] emjaygee:
awww.. that's rude man.. i think my samsung will be hopeless.. will try to give it to samsung service center.. i hate it.. i guess there's no riff jtagbox here in my country... and no one knows about it. im from philippines anyway..
[Upgrading, Modifying and Unlocking] homedog:
yeah ... i don`t know why is so hard to update the rom... now i have 6.0 and i hate it... i want so much to upgrade but i`m scared, i think i gonna go again to that service and get them to update...

if u search i think u have in u`re country riff... ask services ... or maybe its better to give the phone directly to samsung
[Upgrading, Modifying and Unlocking] homedog:
or maybe it is not that hard to update... we are just hopeless :)) we just dont know how to do it :-?? ....
[Upgrading, Modifying and Unlocking] emjaygee:
I managed to update mine.. it was very smooth the first time i made it.. from 6.0 to 6.1 using the official updater from samsung website.. the only problem is that, i repeated doing it after 2 weeks. It's my fault. because of my obsessive-compulsive nature. But i wonder why did the official updater allowed me to do the re-upgrade (6.1-6.1) if it will just brick my device. sigh. i hope samsung service center could still do something about it. :(
[Upgrading, Modifying and Unlocking] emjaygee:
i would also like to know, how to know if your device in bricked? or boot is broken? as far as i know, as long as you can power on the device, and enter the bootloader mode, the device is still ok.. mine can enter to bootloader, and samsung logo.. can even flash PDA, phone, and boot images via mirage successfully.. i just don't know why it happened that i can't enter the windows and stucked at samsung logo always.. :(
[Upgrading, Modifying and Unlocking] heineken78:
Problem is in udl partition of pda is stuck or with flashchip. Its still not bricked cos its powers on and there is possible solution to push it.

Uploaded BOOt and PDA of m480. It is not fully functional with i780 but it doesnt brick i780 (i have tested).

Use mirage to update BOOT and PDA of m480. Then after first system start try to use official i780 files again.

http://www.mediafire.com/file/i8765gk777wug7q/EBOOT and PDA_M480.rar

Notice that with m480 files led will blink red on power on so you should keep power button till its powered on, also your i780 should be connected to power during startup.

After to flash back you need just keep pushing power button while in mirage.

Or try to connect it via async to pc and update via exe updator.
[Upgrading, Modifying and Unlocking] emjaygee:
Hope you don't mind if i ask, sir heineken78 , to clarify some things before i do this.. i really have no solution in mind, so i would rely on you sir.. but im hoping that it would not totally brick my i780. I will do this at my own risk, but sir, i could only do it once. so, i guess i really have to do it right.

This is what im supposed to do right?

1. download your m480 files

2. update the BOOT and PDA rom via mirage (BOOT and PDA so it means, i wont update the PHONE right? How do I know if i did it successfully? Other update using mirage show me a successful download on my PC and phone but still doesn't lead me to windows. Are you saying that after I update my BOOT and PDA with m480 files, i should now be able to enter windows mobile, sync it with activesync then update it using the official updater?(official updater the one you made or the one i downloaded from the internet?) or should i use mirage again but this time holding the power button?) please give me some light sir. Thank you very much for your time. i know it really doesn't concern you, but im glad you are responding. thank you very much.
[Upgrading, Modifying and Unlocking] heineken78:
Yes exactly so!

After flashing if your device is ok, it must load windows,dont touch keyboard of phone will hang. Just reflash with normal BOOt and PDA of i780 after win boot.

If win doesnt boot than its hardware problem.

To enter download mode in within m480 loader: everythings is same as with i780 but when you connect your phone with usb and to start flashing press and hold power button till download begins.
[Upgrading, Modifying and Unlocking] emjaygee:
so my only indicator if it works is if im able to enter windows mobile and pass through the SAMSUNG logo?

I will use the official 6.1 updater PDXH1B1.. but, i guess it also update the Phone image.. would it be ok? I don't have plan of flashing using mirage this time.. because if i'm able to enter windows mobile, then i would be able to sync and flash it with official 6.1 updater. This should be the last option.. i'll do this later at home *cross-finger* :|

sorry if I ask too much. but thank you anyway, and will post my results later..
[Upgrading, Modifying and Unlocking] heineken78:
Its also possible that usb in windows wont work in m480 mode, same as phone..so you wont be able to update via async, only with mirage. Its doesnt matter what version of sam i780 youl be using for revert.

Dont update Phone part- its only case if phone is not working from Windows.

Intention to flash m480 is to erase hidden flags in memory. I hope its should help you to revive i780.

Good luck ;)
[Upgrading, Modifying and Unlocking] homedog:
when mine was briked was able to enter emergency mode and get stuck at first boot image ... with mirage first time for a few days as able to upload boot image and some part of pda, but get stuck, after a few try i was unable to upload boot image... when i go to the phone service they told me that the boot is broken. So my phone was just like yours so i think u have same problem. try to boot with other rom. Heyneken told me when i have the problem that i should try with russian rom 6 ... but ... i tried all the roms from the net but nothing ... so ... i don`t know if u try lots of another rom ... u can do more damages...
[Upgrading, Modifying and Unlocking] emjaygee:
oops. i guess i misunderstood that part. ok, i'll try considering mirage.. but again, i'll just try mirage if i'm able to enter windows mobile after updating with m480 BOOT and PDA. sigh. i guess this would take a lot of concentration. too nervous to do it.

by the way, after updating with m480 boot and PDA, could I update the phone too? so i could keep the PDA and PHONE both in PDXH1B1 version?
[Upgrading, Modifying and Unlocking] emjaygee:
I'm aware of the consequences.. but i'd rather do it with myself than give it with ignorant technicians here in my country.. they're overpricing with the repairs and most of all, if i showed them my i780, they will say, what kind of UNIT is that?

anyway, i was able to update via mirage, and make successful downloads.. no stuck update with PDA or BOOT or PHONE.. it's just that i can't pass through the SAMSUNG LOGO. maybe it's about the flag? im not so sure.. but it make sense..

i also tried the russian version, but no luck.. but i guess the russian version is mainly used for correcting or unlocking the version.. im not so sure.. but that was just my guess..

it's like a pc.. i was able to boot.. to enter the bios.. but was unable to enter the OS. problem is, either the OS is damaged (PDA in this case, which i think less reason) or there's something wrong in the way I boot.. either i'm addressing a different boot directory etc.. maybe in the boot settings.. (which may have connection with the flags)... there is no way i think i could set it up but to try to erase it.. sigh. good luck to me. i really love this phone.
[Upgrading, Modifying and Unlocking] heineken78:
At least you can send me device for JTAG to Ukraine. Il make it for free. I have already bricked and repaired 2 i780 during experiments with Epix bootloader :)
[Upgrading, Modifying and Unlocking] homedog:
my phone was able to go into emergency screen or first logo... but was stuck there... i tried lots and lots of other roms but no luck ... boot image was writible , also first image but get stuck ... after some tries boot image was unreadable ... i go to service with phone and they tell me that the boot section is broken ... riff box write in the phone the boot section directly on the motherboard ... u can try others rom ... heyneken tell me when i have problems that i should use russian rom 6 ... but wont work ... i tried it all ... but no luck ... i think is more easyer to go directly to samsung service. or try agai and again ...

P.S. if the phone is not fully charged the phone wont write ... u need a universal charger to charge u`re battery, even if the light indicates that your battery is charging , she doesnt ... the phone dont know how to charge battery if he dont have a working platform__________

_______________________________________________________________________________________________________________________

Now i read all the data u write... i dont know what to say ... but i think that the boot is still the fault (the phone wont boot) , riff box is the best solution... OR u may send to heyneken the phone ... when mine was broken he was the backup plan but i was lucky and get fixed in romania after long searches....

or u may buy the riff box , in romania is 180euro, so is expensive... but i think u gonna make lots of money with the hardware.

U may try to write the rom again and again ... with others roms ... but ... like me u gonna broke the writable boot, and mirage gonna say that the memory is unwritable...

Hope you have better luck than me... keep us informed :)
[Upgrading, Modifying and Unlocking] emjaygee:
Mr. Heineken, i hope this last resort will work.. in case, you are my last resort.. you are the i780 guy! (now i wonder how much will it cost me to deliver it there... 180euro is so expensive.. i bought my i780 for about 100 USD only..

yeah homedog.. i'll keep you updated.. thank you for your answers also.. sigh. hold tight.. i'll do it tonight..
[Upgrading, Modifying and Unlocking] emjaygee:
I regret to inform you guys that the solution of using m480 PDA and EBOOT ROM didn't work for me :( I managed to download both PDA and EBOOT files to the unit successfully. But after i tried to unplug and switch it on, it still stays on the SAMSUNG LOGO. i feel very sad about it.

Sir heineken78, I guess you are my last resort... now i need to figure out if shipping it to UKRAINE will save me a money than buying another 2nd hand i780. sigh. im really depressed man. it's really the best WM device for me. it packs all the features. but now, it's gone...
[Upgrading, Modifying and Unlocking] homedog:
maybe its better to search a riff box in u`re town or around, i think u gonna find one... see how much gonna cost u and try it ... and if u want to try to send it to heyneken , see maybe u can try with post ofice , they need to have a special delivery , not so expensive. good luck

I was trying to flash to a new version using the Samsung official updater but it got stuck on the "phone image downloading".

So I've reseted the phone but now it doesn't pass the Samsung logo. I've tried using Mirage with some roms I've found here but still no luck: always stuck on the Samsung logo.

Any ideas?
[Upgrading, Modifying and Unlocking] heineken78:
Welcome to club....

Try to reflash phone part, then hardreset.
[Upgrading, Modifying and Unlocking] emjaygee:
seems that many are experiencing these SAMSUNG LOGO stuck up now. :(
[Upgrading, Modifying and Unlocking] heineken78:
looks like 2011 issue :confused:
[Upgrading, Modifying and Unlocking] XanaRaquel:
Ok, I got it to work, yay! No more unbricked i780.

The problem was that I was running Mirage in a Virtual Machine with Windows XP. Tried on a PC with XP and it worked flawless on the first try.

So I suggest to not run Mirage on a Virtual Machine (such as VMware like I as doing).

EDIT PS: I used the ROM from here: http://xdaforums.com/showpost.php?p=8154552&postcount=1117

Used all three parts (eboot, PDA, phone).
[Upgrading, Modifying and Unlocking] emjaygee:
Good for you.. well that's not the case for us.. i've already tried that solution and it still didn't fix the problem. it seems that im the only one in the world who encountered this problem. :( i can successfully download everything but none of them is working :(
[Upgrading, Modifying and Unlocking] tlayn:
I was able to flash the phone and the eboot but not the PDA part. I will try to install WinXP on my rig but I hope 64bit does not matter then I will keep this thread posted. I am in the office right now so I can't do a damn.
[Upgrading, Modifying and Unlocking] emjaygee:
I gave my i780 to the samsung service center here. i wonder if they can fix my issue. I saw that they are just using the same mirage updater. what do you think?
[Upgrading, Modifying and Unlocking] heineken78:
Its their problem, whatever they use they must say a word :)
[Upgrading, Modifying and Unlocking] emjaygee:
I knew it boss, They just texted me. They said that they can't fix the software problem. And now, they are saying that it is a board problem. I really don't think it is a board problem. From what i've observed from the technician, they can't explain the problem. I wonder if they know what "boot" is. They just fix things according to some guided instructions. And if anything didn't work out, they'll just say that "it's a board problem, it can't be fixed." tss. They don't even have that "riff box" that you were talking before.

Sir heineken78, would you like to fix my i780? :)
[Upgrading, Modifying and Unlocking] heineken78:

This guy uses same jtag (riffbox) as I have. And its tested with i780. Good luck !
[Upgrading, Modifying and Unlocking] emjaygee:
I've contacted him sir. Will set at appointment with him and see what he can do. in case he don't know, i'll ask from you what to do. He showed me some pictures of what is he going to do. he'll going to open my samsung, solder some wires to the board. and do the Jtag Riff box thingy then flash rom.
[Upgrading, Modifying and Unlocking] heineken78:
I have now adapter made special for i780 with conacts so dont need to solder, but first time i had ressurected without it )
[Upgrading, Modifying and Unlocking] emjaygee:
If only i you could lend them that adapter... btw, did you make it yourself? If you did, it's good. What schematic diagram did you use? Im concerned with how they will open my i780 :( My i780 is still scratchless and the OEM plastic protector is still intact. they might damaged or scratched my hardware. hope they'll handle it with full care. :(
[Upgrading, Modifying and Unlocking] emjaygee:
Hi mr. Heineken78.

I just received my i780 from the guy you referred to me. He used Jtag and was able to bring back my i780 to life. He flashed a 6.1 rom with 96dpi i think. the screen resolution became big for me.. Everything was ok. But when i inserted a sim card, i780 can't detect it. it still displays that no sim card were inserted.

what do you think is the problem here? could it be because of the ROM? the Phone ROM is DXHH1. and the PHONE ROM is DXHE1. what can i do now? im afraid to brick it again. could it be a hardware problem this time? what do you think? I'm about to return my i780 for repair again, but if i could manage to fix it, then, it would be better. Cause i will spend another time and money to have it repaired again.

Hope you could help me. Thanks.
[Upgrading, Modifying and Unlocking] emjaygee:
Hi, i managed to fix the issue. Thank you heineken78 for the help. JTAG really helped me a lot! it cost me about 30USD for the repair fee.

another man with same problem, i am flashed everthing ok, with all flashes, all options activated. and ALWAYS hangs at samsung logo.

i am flashed too with SPTBOX for samsung with same result.

where i can buy a jtag to repair? only riff jtag can do this?

i have a programmer called usbjtag (www.usbjtag.com) may be i can use.

tnx a lot
[Upgrading, Modifying and Unlocking] heineken78:
may there is hardware prob?

anyway here you can order an riff at http://www.jtagbox.com/category/jtag-dealers/
[Upgrading, Modifying and Unlocking] extrem69:
maybe is software problem.

i cant flash phone part. boot an pda flash ok, but when process arrives at phone flashing, i780 reboot, but in mirage soft appears that cant write because it cant detect phone.

how i can solve this?

using SPTBOX software i can flash all parts. but only can use his special flashes.

Just a reminder to back up your EFS and persist in TWRP to avoid disastrous consequences. These house code that keeps your IMEI and VoLTE working as they should. If you end up losing you IMEI, 4G, or your VoLTE, restoring these will save you. I don't think the official TWRP offers a way to back up persist, so you can back it up using this unofficial image.

IF YOU FLASH STOCK ROM WITH FASTBOOT, YOU WILL LOSE YOUR IMEI!

Don't attempt to go back to stock with fastboot. Instead, use the TWRP flashable stock ROM found at this link. It is not perfect from what I have heard, but it is worth keeping your IMEI and your VoLTE intact.

If you have already lost your IMEI/VoLTE/4G, there is currently NO SOLUTION. The official 8.1 update is nearing us and we can only hope that it will fix this issue.
[Moto G5 Plus Guides, News, & Discussion] guillermohs9:
Good info and thanks for the heads up. I was about to flash Oreo these days. Although I always backup EFS, I don't know if official TWRP has persist backup support, but I found this and thought I'd share it.

Nope! It won't. It only overwrites the recovery partition. :svetius:

yep seems that i'm the latest statistic, lost imei and now stuck with only 3G at best. Tried everything with no luck so heres hoping that oreo with fix it or the phone is going in the trash and I'm going with Nokia or Sony for the next device. Not the devs fault as this was my doing of trusting a presist file from an xda post, still moto should allow users to rollback firmware succesfully like any other oem ex. HTC.

Actually, there is a fix around which works. I can tell by first hand experience. My VoLTE never worked with my Potter until today. I read this thread thoroughly and I still can't believe it's working :laugh:

When you flash back to stock from Oreo roms or flash stock firmware again you will automatically lose IMEI and network connectivity.

Here's the Persist file linked in my first guide https://xdaforums.com/g5-plus/how-to/moto-g5-xt1687-retus-s-unlocked-retail-t3806954 :

https://www23.zippyshare.com/v/13MfpRhg/file.html

TWRP recovery needs to be fastboot flashed again after you flash back to the stock firmware.

You need to make an EFS backup in TWRP Recovery to create the EFS folder in your phone storage, after you flash stock rom.

The persist.img backup needs to be restored in TWRP after you place it in your phone storage > TWRP folder > newly created EFS backup folder

Restore persist.img in TWRP after flashing stock firmware, you should not be flashing firmware only. Persist.img is what gives you your LTE network signal and IMEI back.
