Epic 4G Touch - Can not restore to factory ROM

First Android phone and experience rooting, tried google'ing couldn't find anything. So hopefully someone where can help.
I rooted my phone previously and lost WiFi ... Everything else works perfectly except WiFi turns on, scans, can't find any networks and shuts off. Now I just want to go back to stock factory ROM until I can research another rooting method.
I used this post http://forum.xda-developers.com/showthread.php?p=20956793 and get through the whole process but it stays on "Establishing Connection" then Odin just says "FAILED". Below is my info of the phone, could someone help me out here, either provide a link or another method... I haven't tried the 3 step process of restoring each kernel, rom and modem yet, as I'm not exactly sure how to do that ... Do I just pick "PDA" then load all three file in Odin at once, then start the process??

Build Number: GINGERBREAD.EK02
Hardware Revision D710.10

I followed this video exactly, and it worked fine.

Some things that can cause errors in odin if the video above doesnt work:
- Try a different micro usb cable
- Try a different usb port
- Try removing the sd card
- uninstall/reinstall the drivers
- Try removing the battery
One thing to note, if odin says pass but the phone doesn't reboot... pull the battery and power down, then boot into stock android recovery and wipe data/factory reset (this process is also shown in the video @ 6:15).

BTW ... If there is another Rooted ROM with working WiFi( and everything else ) then I'd be happy to try using Odin to get to that ROM instead of Stock. Really just need WiFi back for now.
Thanks again!

[Q] Can't Flash Modem

My Phone
Model #: SPH-D710
Android Version: 2.3.4
Baseband Version: UNKNOWN
Kernel Version: 2.6.35.7-SPH-D710.EG30-CL435734
Build #: Tnz BLEND v1.4
Hardware Version: UNKNOWN
I bought the phone second hand with the Tnz rom installed and it worked fine. I tried to flash CM9 with ODIN and it failed. I restored it and now I have no signal. Now I can't get ODIN to recognize the phone on either my desktop or laptop with any of my 3 data cables and when I try to flash a modem in CWM v5.0.2.7 (Using the .zip from the Wiki) it gets all the way to the end and then I get this message:
Code:
script aborted (no error messege) E:Error in /emmc/update-modem-EG30-FULL-CWM.zip
(Status 7)
Installayion aborted
I checked the zip with winrar both on on my computer and when it's on the phone and it checks out. At this point I'm out of ideas so any help would be greatly appreciated

Why not start over.
Download the EL26+CWM kenel [http://kernelrepo.chris41g.org/defa...Chris41g\ACS\ZIP&filename=EL26_StockACS5.zip], the EL29 modem [http://www.buildarom.com/E4GT/Modems/E4GT_Modem_EL29.zip] and something like Calkulin's stock rooted EL29 [http://forum.xda-developers.com/showthread.php?t=1332837] Copy them to the SD card (on you computer) then put the SD card into the device, Flash the EL26+CWM. Use that CWM (EL26 one) to factory reset.
Then install the modem. Then the ROM. and see what happens.
Hope you didn't use ROM manager by the way - that's a BIG no no.

You might be in trouble.
Can you boot into download mode? If you can use EL29 oneclick to get back to stock.

Thank you both for your quick replies.
I was able to flash the kernel but when I tried to flash the modem I got the same error message. The 1-click recovery won't recognize my phone in download mode, just like ODIN.
I think I'm in trouble :crying:

Yeah u may have bricked....cm9 isn't an Odin type flash. Everytime someone says their PC won't recognize the phone they wind up bricked. Read through the how not to brick your phone thread in general and hopefully someone found a workaround.
Can you get into a cwm recovery even with volume up+power? Not the stock one, but a custom recovery without the android in the background.

Well shoot, guess its time to start digging....
Yes I can boot into CWM, that's what I was using to try and flash things.

I have had some kind of luck playing around with the nv_data files using this http://forum.xda-developers.com/showthread.php?t=1264021
I browsed my EFS directory and created blank nv_data files with root explorer.
After the reboot I had empty signal bars come up at the top and my Baseband fields filed out with the correct version and with my IMEI back.
This however only lasted about a minute before I got a crossed out circle for the signal and I back to Unknown values for the versions.
I had my phone connected to the PC the whole time and I also noticed my PC was repeatedly making the sound that it recognized a usb device (samsung mobile modem diagnostic serial port, I believe) until the phone lost the bars and went back to Unknown values.
Now my pc won't even detect the samsung diagnostic modem at all.
Also when I try to go into Setting -> About phone -> Status, I get a force close of com.android.phone

what cm9 zip did you flash! what is the file name? did you get it from cyanogenmod.com?

I fixed my issue via tips from other threads
I odin flashed stock gingerbread
After boot, I was prompted for sprint update to FF18, which I let run while I was searching out FF18 modem.
Then Odin 1.85 flashed ff18 modem in phone slot with EFS clear & reboot checked
After reboot, signal bars were back & phone initiated activation
hope this helps someone else

I just had this same issue -- tried to flash a modem and booted back up and no service, unknown baseband version, etc etc. I thought I had bricked it, but I managed to nurse it back to health. Here's what I did:
Went to the recover from bad flash topic in Dev forum and flashed that (though it doesn't flash a modem)
Then flashed FH13 modem
Then flashed Blue Kuban ROM (which is based on FH13)
Then booted into that and I have signal and baseband is recognized as FH13

Baseband Hardware "Unknown" Fix
Just had this same problem, 30k ft. overview of issue; I was messing around with flashing NV-items in DFS and reset RF and must have loaded the wrong .ncf file or something, not sure, and ended up with the same problem. Baseband and hardware versions are "unknown". Tried your fix with fix bad flash topic in DEV and FH13 modem with blue kuban with no luck. Still unknown versions. When I review the cutany app with serial and read the model it is reading out: GT s5 670_EUR and this is the SPH-D7710 Galaxy S2 Epic Touch 4G. SO......umm...
I have tried:
- flashing a few other roms and modems. no luck
- tired editing the NV items. but can't get back into Diag mode. (may try above post.)
- reset the ##7886#
- wiped /efs and restored it.
- went to stock EK02 unrooted
- rooted and unrooted
-
Thoughts:
- maybe get the right firmware radio/ hardware and manually flash them (where to get them or what is it that i need?.)?
- edit the build.prop to get a different build that fits the model?
- some how trying to fix com.android.phone? not sure how it works?
- some how, wipe every thing on root? and start over? not sure this can happen?
- read-only error when trying to edit root dir, ? have adb
So in summary I need some direction asap!

I had a similar issue and finally fixed by first flashing the oldest working nandroid backup I had, then flashing stock sprint gingerbread (unrooted - as if I would be returning to a sprint store) using one click (available here on xda) which restores system to out of box state.
I had to switch out to different usb cable AND a different usb port to get comm port to be recognized. I also restored a QPST backup.
After reboot, baseband & IMEI were restored. Sprint prompted to install system update, which I believe corrected the other remaining glitches.
I then flashed FF18 and all is well now, except...
I did discover day or so later that usb charging port is going --- I suspect that may have contributed to the freaky disappearing baseband.
Perhaps a bad connection (yikes!) during one of my marathon flashing sessions.
Now having port replaced.

Sounds like you are heading in the right direction(s) for a possible fix.
You can't get into diag on some ROMs because you can't access them via the dialer and/or they are not there and/or supported.
What I'd do first is use one of sfhub's One-clicks and do a full reset. (I'd probably choose FF18 http://forum.xda-developers.com/showthread.php?t=1721229).
One other thing I'd mention is to check the md5sum on EVERY download. Bad downloads are the cause of SO many issues.
Then, once it's back up 'Activate this phone' then try a update PRL and Update Profile.
Again this is what I would do. You could spend days trying to figure it out and not get the solution. But if you'd like to use your phone why not bite the bullet; do a full wipe and make sure your phone works as, well a phone.
Then add a safe CWM kernel (Agat 5.4 or rujelus22 1.8) via sfhub's Autoroot or Mobile Odin.
From there you can then mess with other ROMs, modems and kernels. Check out rwilco's repository for modems and kernels. He's done a great job of organizing and putting together CWM flashable zips, tars and One-Clicks
Good Luck!

Lol "during one of my marathon flashing sessions"!! started this journey at 4pm PST today.
Thus far>
- Back to stock unrooted applied all updates ota (wifi) at FF18 4.0.4b (IMM761.FF18)
- reviewed my anycut serial number still says 1. model GT-s5670_EUR with blank imei and s/n (this may have been from the bad NV flash in DFS?
- will try QPST restore my.qcn file,
HOW did you get into Diag mode? tried ##8778# with CP and ALL but QSPT still can not find my usb connection? so I can restore the qcn?

OH wow, was this flashed with an international version!? Looks like it.
You may need a jtag repair or replacement.

Did you try flashing with regular Odin - not the one click downloader - and checking the EFS clear option?
There is another one that someone mentioned but I can't recall what it was now that will force the NVDATA back to factory setting. I'll see if I can find it.

Thanks, been working on this one for almost 18hrs. Have a timer going. Might be a new record...I'm sure of it that the root of all evil here was DFS and the lack of programing literature, basically trial and error, just in this case more error then trial....
I spoke with a tech in the Sprint back repair center reaching out into the dark here for the lowest guy on the ladder, not much help, but just gave it a shot in the dark with all honesty, and technically they are not skilled to handle this kind of thing, they have manual programing ability with some internal portal software, but not Samsung hardware programing or chip Qualcomm tools. (not sure that is the issue here) basically said exchange it for a referb. Or find hardware firmware or something..Wasn't sure what to say....
So about to toss in a towel here, but, yes tried using different odin's and clearing efs. Also tried again to delete /esf and place /efs.bak with edited nv_data.bin etc.. from other topics. I have a back up of my nvf file from DFS demo. I just can't get to the port to flash it on CP mode, as it will not connect. I don't know were the files go within root to replace them manually?? Some how have a hunch that its a simple copy and paste or delete edit some where.
The wrong model no. is what is driving me off the wall, maybe though the phone usb with some other software (NVFlash? ANYONE know if that needs Daig mode of just a usb to root access? Also maybe ADB shell cp those specific modems and flash files for that EURO model?.humm..
(Thinking out-loud here, but I think it is possible to in theory to flash other phone model and have them working on different networks if the hardware provides it. Would be cool idea and ultimate hack to get the Mifi and clone it to E4gT or find a way to tape it to the back of your epic for $34.99 all you need is data to use SIP Droid and G voice for all voice and text and the SIP following you as long as your either on good wifi or a 3g data connection, not sure about 1x and SIP but if you lived in a good coverage area this would work great no more $100 bills, otherwise Boost Mobile for $15 a month for data Pay as you go using SIP..Cool Technology these days pretty soon there will be no more cell phone channels it will all be data..
That's about it for me, maybe one more hour of reading posts and googling for any other leads to fix this mess, other wise hale marry and turnover on the 20 yard line for this one man team.
Thanks to all that replied.

[Q] cant flash 4.1.2 after botched 4.3 ROM attempt?

I wasn't paying attention to the model numbers I was looking at and tried to install an N7100 ROM on my SGH-T889. I installed it, fudged my IMEI and tried to rollback to the previous ROM I had in place but it didn't resolve my IMEI unknown issue. I tried to restore my backups, nothing. I have tried multiple stock firmware versions for my phone I have found on here but ODIN fails on every single one, most of them sitting at boot.img, MD5 hash invalid or getting stuck on system. I am unable to get into recovery, only the download screen. I think because the ROM I tried was 4.3 it messed up my bootloader and wont let me go back to 4.1.2 but I cant put anything on it at this point. Ive tried multiple versions of ODIN, different USB ports, cables, rebooted my PC and Im out of ideas at this point. I apologize in advance because I'm sure the answer is out there I just cant find it and I've been looking for a few days.

Its possible that when you tried to flash 4,3 rom you also ended up with the stupid KNOX security thing. Which means you cant go back to older roms only 4.3. (as far as i know, im still a bit of a noob with this stuff)
It might be usefull to post what you get on the screen when in download mode, hat will give people more info to help you with i guess.
I did a similar thing too you a while ago and lose my imei and such, i cant exactly remember how i fixed it, i think i just flashed a stock from from sammobile.
If you havent tried that, then go here http://forum.xda-developers.com/showthread.php?t=2032849

Did you try flashing stock 4.3 ROM for SGH-T889 from sammobile ?
Try flashing the MK7 modem ? You can find it under development forums.

I did indeed, although The modem I tried now that I am looking back through my downloads I believe was for the N7000 model. I will look through it and try to find it. Thanks for your reply.

I seem to have gotten myself out of the hole Ive dug. Hopefully if anyone else gets this deep, this will help. Given the fact that I erroneously flashed a 4.3 ROM I screwed myself over for going back but I was able to flash the latest firmware from sammobile (4.3) The file should be named T889UVUCMK7_T889TMBCMK7_TMB. I unzipped it, reinstalled ODIN 3.09 and tried a few times with negative results. However, Ive seen several conflicting posts about Kies, some say delete it completely, some say use it so I reinstalled it BUT I ended the process in task manager before I connected my phone and opened ODIN. I flashed only the firmware in the PDA section, no .pit files, no .phone files. It completed after about 10 minutes and I now have a stock 4.3 note 2, wifi capable and data service enabled. My download screen still shows custom binary download8 counts) which I know I can revert using triangle away but current binary and system status both show samsung official. The Knox warranty void still shows:1. Tmobile has sent me a replacement due to my negligence and ignorance in reaching out to them and I have 2 phones, the one I just fixed and the warrantied replacement on 4.1.2 sitting next to it. Should I just return the replacement back to them and tell them I fixed my issue or should I send them the old phone and keep the refurb? Im not familiar with the procedures phone companies follow when it comes to inspecting phones that are sent back to them but it seems to me that it is an expensive gamble because if they get my old one and see the Knox tripped, I imagine they would claim its out of warranty and charge me some astronomical amount.

Rom for lte version, then he had issues with efs file and someone edited them and fixed them, now this image I attachedis stuck on screen, wondering if I unroot and go back to stock will that fix issue that I have shown on attachment, thank you any help is appreciated
Sent from my SGH-T999 using XDA Free mobile app

just shooting from the hip here, you don't have a backup of your previous rom? if you do, and can still get to recovery, I'd wipe everything and flash that. Baring that, you could TRY to unroot it, but I wouldn't guarantee anything. Maybe someone else has better info than me

Yea he didn't do a back up, smh, so he attempted to unroot last night and he tried flashing stock 4.3 but Odin gave him a failed. Then asked him what android version he was previously on and he says maybe 4.2 or 4.3 now phone is saying connect to lies and run recovery and still can get to download mode, told him I will try to fix it and leave it alone, any help would be appreciated on what stock rom I should flash

try kies, there is an option for "emergency recovery", then just reroot

Do I need to put phone download mode and run recovery in kies? also to go back to stock which stock rom do i flash?

no, just turn the phone on, then connect to USB... kies will determine the firmware...

Ok cool when I turn phone on it shows the connect to kies to recovery but recovery ask for some kind of code

also when i turn the phone on and put it into download mode this is what i have on top left corner
ODIN MODE
PRODUCT NAME:SGH-T999
CUSTOM BINARY DOWNLOAD: no
CURRENT BINARY: Samsung official
SYSTEM STATUS: none
QUALCOMM SECUREBOOT: ENABLE
Warranty Bit: 1
BOOTLOADER AP SWREV: 1

You don't need to be in odin mode to use Kies, but since you can put the phone in odin mode, go to samfirmware and download the latest firmware, then flash it. You still might have to fix the EFS though.

ok cool thank you,, ok i flashed stock rom,everything went good, but i am stil having that image on screen still,which i attached earlier,any help on how to remove that image on screen? will rooting the device and flashing rom remove that image from screen?

ok after searching on google found out its factory mode image thats on the screen, i tried doing this(http://www.droidforums.net/threads/how-to-exit-factory-mode-to-user-mode-in-s3-help.239945/) but folder is empty and no back up, would like to know if there is a fix and can someone help please.thank you

So is this what you did?
su
echo -n ON > /efs/FactoryApp/factorymode
Are you absolutely certain you typed it in correctly? What did it say after you entered the command?
You said the folder is empty, did you actually look at the /efs folder and it was empty??? If so, I'm not sure if theres much you can do tbh. There is device specific information there so it is unique for every device. You might be able to get some stuff back (non-unique type things), but I don't know about the rest.....DRM keys and more.....
If the folder is empty, how did you determine this? What app did you use to check it out?
You said you flashed your firmware via Odin right? Not Mobile Odin? Big difference so i just want to make sure.
It would be a big help if you could elaborate on your OP. What exactly did he flash, and how did he flash it? What was the original problem? What were the efs issues you eluded to? And more importantly what did someone edit and supposedly fix?
The only problem I have ever seen related to the efs on this device is the one you originally posted about, the FactoryMode window. Aside from that very rare issue, I have never seen any problem with the efs on the Qualcomm S3's. Many people automatically go there because OTHER devices store different information there and they expect it to be the exact same for some reason. Anyway, what I am trying to say here, is other than getting rid of FactoryMode, I can't think of anything else anyone would need to touch on that partition. This is why it is very important to know what the other person "fixed", and how.
In the meantime, go to Settings > About Device > Status, and verify the IMEI is there and that it matches the one printed on the sticker under the battery. (Am I correct in guessing all of this started with some sort of IMEI issue?) If the IMEI is anything but correct (missing, zeroed, incorrect, etc), PM me directly. Do not worry about posting again until we solve that. Chances are, if the IMEI is the problem, fixing it will solve the rest too. Unfortunately, we are not allowed to post, link or discuss that in the public forum, so I can only help via PM if that is the problem.

Bricked Galaxy A3 2017

Hello everyone, I decided to root my phone today. First I enabled OEM unlock and then installed TWRP, no problems with that. Then I tried to install CF autoroot through recovery and everything seemed fine. When I tried to boot up my phone it said something like integrity check failed and I had to do a factory reset to be able to even start the phone. I did not do that but tried to install official samsung oreo firmware through odin but it won't install, just fails. Then i got other error message saying "an error occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software". The only thing I can do now is enter download mode and nothing else but odin does not let me flash anything. I'm desperate here so any suggestion would be great. Model is SM A-320FL btw. Sorry for my english and lengthy post

What kind of error do you get in Odin?
Is it the one that says something like "SW Rev. check fail"?
If so than for me it worked to flash the bootloader and modem of Oreo and the after that i reinstalled the OS without any problems.

First it was just a red fail for BL, CSC and those other things and later it just won't even start. When I try to install TWRP it goes to half and stays there. Thanks for the suggestion though.

Was your device from a carrier, if so, try to flash the firmware that your device came with. If you can't solve this, PM me, so that we can try to resolve this on Telegram, Discord etc. :highfive:

Thank you for the reply, I don't think it was from carrier, when I tried to flash firmware I downloaded latest firmware from my current carrier so I think that shouldn't be a problem. I'll contact you tomorrow because i'm just too tired now. And update, I can flash TWRP now if that is of any help.

It is solved now, thanks everyone for your help

Hi. Glad to see you got this sorted, but it may be useful for other users to see what you did to resolve this.

Yes, how did you solved that.
Looking at two A320F I found one difference:
One has AP SWREV B:2 K:0 S:0
the other one (that makes trouble): AP SWREV B:3 K:1 S:1
What exactly does it mean.
Flashing with Odin gave me erros (on device, Odin just say "failed") depending on flashing BL (SW Rev Check failed )Bootlader Device: 3, binary: 2 , while flashing AP gives Kernel Rev check fail.
So, how to go on? I was able to flash TWRP, but not Stock (neither an old 6.0 nor 8.0).

Ok, solved it. Flashing stock will probably only work to same or newer versions, not for downgrade (at least not without any special tricks that I don't know).
After downloading the latest stock FW , odin passed.
Now I still have the problem, that I can't transfer data partion from one A3 to another one.

My first error was that I downloaded wrong firmware for my phone and because of that odin gave me errors. Second error was that I tried to wipe data through advanced wipe, but I needed to format it by pressing format data button. After doing that I was able to flash official stock ROM, install TWRP and root my phone. User MartinYTCZ helped me greatly with this, big thanks to him again. :victory:

Can't you backup your internal storage on PC or SD card, contacts, messages, phone calls, settings on samsung account and apps and data with titanium backup? When I flashed stock ROM I lost all data from my phone so be careful with that.
