[Q] how to flash epic back to sprint - Epic 4G General

ok i made a dumb decision i had my epic with a clean esn flashed to metro pcs and i plan on getting back with sprint asap but my problem is my epic is still under metro i already flashed the phone back to stock 2.1 and i unrooted but when i dial *2 it takes me to metro customer service ive seen a few post on other sites on how to get it back to sprint but i trust xda for help

You need to fix the radio programming. SID, NAM, etc.
It really isn't "flash" at all. They haven't modified firmwares on modern phones. All it is is simple network parameter programming.

Hey delawaresace,
I'm in the same situation as atmk4shh, where i want to flash my phone back to Sprint from Metro. Could you copy and paste that PM to me also by any chance? Your help would be much appreciated!
What I have done so far:
- I flashed it back to DK18 stock for sprint
- Selected "wipe data/factory reset" and "wipe cache partition" 3 times.
- Added my phone ESN to sprint plan and ported number over successfully.
- Did the ##786# reset
I believe the problem is probably has to do with my QPST settings and when i open Service Programming i still see the metroPCS info. And me being the idiot i am, didnt save the original settings, so I was wondering if anyone could post that info? Or am I barking up the wrong tree here? Also, i was wondering if i need to change anything else to get my phone working on sprint again? Do I need to do PRL stuff on CDMA? Thanks again!

Most likely you need to load a Sprint PRL to connect to Sprint towers, latest one is 60674. If i remember correctly, QPST and cdma ws can upload a prl file.

Thanks lord for the suggestion, but sadly I have already tried that and no luck. I think it might have do to with the NAI, Tethered NAI, UM, AM settings
Update: got the voice and sms to work, but data arrows arent showing still

Have you tried samsung's dialer code for factory resetting? I belie it restores the programming to factory as well. The just update prl/profile

Yeah, i believe thats what the ##786# reset is: the factory reset. That hasnt allowed the data arrows to show, let alone push through. I also have updated the prl to, but it wont let me update the profile without network connection. Thanks for the suggestion though!
UPDATE: Brought it in to the sprint store. They couldn't fix it. Gave me a replacement. I tried to save it...i really did lol. Thanks for all the help though!

Flashing to Cricket problems

Okay, so I called Cricket to get the MSID/MIN but i get an answering machine that says that they do not offer customer service at this time...is their any other way of obtaining this?
Technically, if you have a phone that's already on Cricket that you have the drivers for on your Windows computer, and you can get it to work in QPST, you could find all of the settings.
But it's not really worth all that trouble if you don't.
Just call *611 from a Cricket phone. Maybe they don't have Customer Service on Sundays?
Or go into an actual Cricket store, if they are open, because they will help you get the numbers too!
sorry to bother, I've been looking at different threads but can't find how to set those numbers on the eris

You need QPST and the Eris drivers. Go to this thread for instructions on how to use QPST. You could also do it with EPST on the handset itself (##778).
http://www.howardforums.com/showthr...an-HTC-Droid-Eris-to-Metro-PCS-(Tutorial-v2.0)
If you're on an Eris-based SenseUI ROM, you don't need QPST at all (in fact, I never heard of it the first time I put my ex-gf's phone on Cricket).
Just dial ##778
If you're on a different ROM, then yes. You may find it best to flash a SenseUI ROM anyway if that Froyo ROM doesn't have ##DIAG (whatever the numbers that line up with d-i-a-g are, I forget).
Put your phone in ##DIAG mode, open Device Manager in Windows, make sure the driver is installed, then in Device Manager, change the COM port of the diag device to like COM1 or COM3 or something low enough for QPST to see it.
Then in QPST, open up your FFA Surf (whatever it's called) phone, and edit all of your settings there.
WAY EASIER to just boot into recovery
make a nand backup
wipe data/cache
flash Ivan's Eris_Official 1.0 or Plane Jane (or something)
Boot up just enough to dial ##778
Put in your settings and PRL file
Reboot the phone
Make sure calls and texts work (after you tell Cricket your serial number)
Boot back into recovery, do a NAND RESTORE of your Froyo rom
stay in recovery, flash the cricket v10 flash
reboot
profit
I work for cricket mon-fri 2pm - 7pm, if you ever need help with your account/features feel free to pm me
I got it! Thanks guys

How to un-root/de-root your Mytouch 3G Slide

Before I begin, I'd like to say that I know we have posted this everywhere.
The reason of this thread is because there are no real clear instructions on how to un-root, and there is no actual thread, hence the reason we get this question asked so much; something I want to eliminate.
How to UNROOT your Mytouch 3G Slide
[Optional] If you are sending back your phone to Tmobile for replacement, make sure you flash the newest radio out as of now. (this at the moment is 7.09) [/Optional]
1) You will need to download "ESPRIMG(2).zip" from this thread (This is all you need, you dont need anything else)
http://forum.xda-developers.com/showthread.php?t=713507
2) Rename "ESPRIMG(2).zip" to: ESPRIMG.zip
3) Place the new renamed file ESPRIMG.zip in the root of you SD card (this means in no folder)
4) Power off your phone any way you like
5) Turn your phone on while HOLDING: VOLUME DOWN and POWER.
This will get you to a screen where you will need to wait for some loading. Let it load.
6) Once above step has finished, phone will give you some options. Hit VOLUME UP to confirm flash
7) It will take some time, and when it's done, you will be unrooted with the stock Espresso.
Credits go to: eugene373, xda-fourms, CaliBoyPhillip, and some guy I cant remember
reserved for future way to unroot
I posted the ESRIMG.zip in the q&a section a few days ago, nice catch on the radio. I totally forgot about that for warranty reasons. This thread should hit the New Bible!

ask that in the Question and Answer forum of mytouch 3g slide.. im not too sure of what you're saying, and you'll get more answers there.
Hey Xologist,
Thanks for this post but I have a few things you might want to add on.
Your link to eugene373's ESPRIMG(2).zip works fine, but wouldn't auto update after a week. So instead of waiting to be updated I re-rooted and then un-rooted to 1.27.531.1 using the ESPRIMG that wegarner provided. After that I was able to do the manual OTA update without root.
wesgarner (1.27.531.1)
http://db.androidspin.com/androidspin_filedownload.asp?release=280&type=1
So after someone unroots they can just manually update(root not needed) to the current OTA via ChiefzReloaded's provided files.
-7.09.35.10 radio -1.35.531.1 build

Same file with a mirror.However, the google one ended up working for me.
I am assuming this will result in a factory wipe/reset as well, correct? I'm considering switching back to stock from Cyanogen 6.1.1 since it's unable to send or receive MMS messages for me but I'm afraid I may lose the pending messages if I revert back and won't be able to recover or view them.

Yeah it'll be a factory reset but you should still the messages as long as the phone hasn't actually grabbed them from the companies server. As for the actual issue, have you verified APN settings? I was having issues with MMS and data when I first flashed CM 7 and ended up switching to T-Mobiles alternate server to fix.

Thank you for confirming that this would wipe the device. I was also not aware that the MMS messages would still be retrievable if they have not yet been downloaded to the device (good to know!).
I see you have found my post on these forums in regards to my issue, so I will not get into the specifics in this topic, but yes, I have confirmed the APN settings several times now.
I've tried this, but I keep getting this error... "Main Version is older"
I need to unroot because I need to send my phone in for warranty service... my power button stopped working... makes it realy difficult to get into recovery mode or anything (impossible) but I can get into the boot loader
What can I do to remedy this?
Heck, if you could tell me how to corrupt the system folders I would do that so they couldn't tell it was rooted at all...
I've tried doing it this way and I extracted the file to the root of my SD card. But when I followed the steps, all it did was take me through like I was doing a reset of my phone. Didn't remove the actual ROM. Am I not supposed to extract it? What can I do to remove this ROM because I really don't like it on my phone.
you do not extract the zip file. you just put the ESPRIMG.zip file into your root folder. when you boot into recovery mode, the phone should automatically start searching for it (you might want to give it a little time to let everything load up). it will load (this will take a while) then press volume up to update when prompted. thanks to the OP for putting this up. you saved my butt, i have to return my phone for warranty replacement because the touchscreen and all the buttons stopped working.
Hey xologist, I'm sorry but I'm still very new to rooting. I've had some issues with the touchscreen and need to send my phone in for the warranty so I need to unroot it. What do you mean by flashing the newest radio? Where do I get it and how do I flash it?

you probably placed a different sim card in your phone because this phone is normally locked to T-Mobile. if you're on T-Mobile and want to use a different sim card, give them a call and they will get you an unlock code for free. if you thought you bought the phone unlocked (not locked to a carrier, T-Mobile), then it's not, return it to the seller or something.
I tried the esprimg.zip on the root of the sd card but every time it tries to apply it it says it is the wrong image and aborts. Any ideas?
no matter what i do i cant get it to install anything, i install and apply the esprimg.zip file, re boot, and still loads CM i may have forgot how to do all this fancey root stuff, i have Cm 7.1, can i pleeeease get a dummy version to unroot
Hi all, in a pickle here. I will be attempting to remove root and am on CM 7.1 stable. My obstacle is my volume buttons don't work. I'm removing root for warranty/return reasons, is there any way to go back to stock other than from the bootloader(sp?)? Thanks, all!
(2/12/12)So I ended up flashing CR's 2.2 rooted rom so that I could upgrade through HTC Sync to the 2.2 stock update. Thanks anyway

[Q] EVO SHIFT on METRO and needs to revert back to SPRINT/STOCK

Hi Folks, please bear with me. Before some screams google/search for it, I have already, and I have a very small window of time to continue to search thru hundreds of threads.
Mods: Because of the circumstances, I have to double post here and in the evo shift section. Main reason for posting here is because there has been more success here and more attention/traffic is paid to the evo, whereas since the shift is the evo child, I figured its harmless to double post. Sorry if Im bending/breaking the rules.
I have an evo shift that at the time of purchased was already flashed over to METRO. My shift has a clean esn and I would like to flash it back over to sprint. Yes, there are guides here, but the only guide I found was how to flash the EVO 4G over to METRO but I dont recall reading how to flash back to sprint. http://forum.xda-developers.com/show...50#post8395950
Then I went here: http://forum.xda-developers.com/show...3#post14282143 to acquire the qpst tool. The link there is an empty torrent, so no luck.
But the reason I am posting is because I know there are others who want to flash their evo shifts over to metro, and I already have an evo shift on metro. So before I start tinkering around and potentially BRICK my shift, I'd like someone to walk me thru the process of saving a dump of everything on my phone so others can learn how it was flashed or check certain settings in it, or just have whatever rom that it is on. So basically, so the next set of ppl can benefit from it.
All I want to do is go back to stock/sprint so I swap my epic off and shift on. Im curious about the insane overclocks 1.7+ghz, so i can determine which phone I want to sell. Thats it. Hope someone can help me out. Thanks in advance.
Ok, since this is the SHIFT forum, does anybody think this will work?

All you should need to do is run the stock RUU to take it back to the original setup. After running the RUU you should be back to Sprint original. No ROOT. Just like it came out of the box. Check either of the links below to get back to the STOCK RUU. Hope it helps.

Thanks guys, but I guess the other prob is how do I make a full back up so others can flash if they switch from sprint to metro?
Or should I not concern myself with that because its a matter of qpst programming (among other tools)?
lilgrass71- thanks for the link, but i believe i need version 2.7.366,
at x-drivers, they have 2.7.323, which I assume will be slightly outdated to use for the shift. any other ideas as to how to acquire 2.7.366,
i googled it, downloaded a few, and just waaaayyyyy tooo many viruses. I understand majority of AV's will throw a false positive, but I feel much much safer getting whatever app from a trusted source and not just some random file hosting spot where as anyone could have tampered with it. Hell, dont even mind the tampering, as long as someone who is "well known" does the tampering for OUR BENEFIT.
That version will work... I used it on my shift and it works fine. What are you trying to do with it? Just a backup of provision data? Or mess with the memory data?
Sent from my PG06100 using XDA Premium App
If someone can benefit from my backup then I would like to make a complete backup of everything on the phone. If my backup cannot be used, then I will skip that process and flash back to sprint. But yea, thats the only reason why I would do a backup, just to help out the next set of ppl.
Also, since you have used this tool before to revert back to sprint, did you have to flash the ruu that pr posted? or u just used qpst only and flashed whatever rom? im asking because I really dont want to tamper with qpst as that may be a lil more dangerous than just flashing a stock rom.
I believe there's a bit more involved to flash over to Metro PCS. I would suggest just running the RUU and calling it good.
lol, pr, Im not trying to flash OVER TO METRO, im trying to flash BACK to sprint.
Ive tried using the .zip that goes on the sd card, that does not work.
Ive tried using the ruu stock flash utility, i keep getting "cant connect" error. Im running win 7 x64, i've installed the htc diag driver correctly, verified it works, it was on port 8, i changed it to port 9 to see if i would have better results, that didnt work, changed usb ports, that dont work, shut off phone and pc, that didnt work. Im at my wits end. right now, im still browsing thru a bunch of other threads to see what might work.
I have not tried lilgrass qpst way yet, thats my last resort, but I will if i get TOOOO frustrated.
I know that. By RUU I meant back to Sprint. That's what the links I posted are for. Connect to computer with USB cable ( HTC cable, not generic ) . Then launch the RUU from your computer. Should prompt you through the process. The reason I said about the HTC cable is because I've had issues with the generic cables in the past.
If u want to revert back to sprint, made sure the your meid matched the one on the serial number.
Hook up your phone to its com port, open qpst and connect to the phone. Leave that open. Then goto qpst programming and clear out the username and passwords for profile 0 and profile 1. Make sure you write it to the phone.
Then your gonna want to just run thr ruu to get yourself back to stock and run a epst profile update and it will update all your phone programing over the air.
I didn't go back to stock. I use the programs for higher process hexidecimal memory editing but that should do the trick. All the cdma phones work just about the same way when they connect to the network. Don't buy into the you need to buy into the primier data/the phone won't work without this plan bs they give you at the store.

prboy- last night i did use the ruu, i flashed it, it worked, but still had the sprint banner there, but now i have even bigger problems, i will explain a lil later tho.
lilgrass-i did not use the qpst method yet, i used prboy links, but after trying to root my phone, i bricked it, which i now have to start a new thread. boy oh boy, problems after problems.
oh, the meid does match on the box and phone itself.

Can anyone share the 4G LTE system/boot dump?

I tried to use the rooted 3.2.2 rom that was listed under development, but I could never get my wifi to connect. Now I am unable to get my 4G to work. I used to have the option to choose preferred network mode LTE/CDMA, but now that no longer shows. I am on 3.2.2 using build HLK42B.
I was wondering if someone who received their xoom back from the upgrade has the latest image I can try.

You need to flash the modded recovery, then in adb shell, run
mount /data
mkdir /data/media/Stock
dd if=/dev/block/platform/sdhci-tegra.3/by-name/system of=/data/media/Stock/system.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/boot of=/data/media/Stock/boot.img
sync
Then reboot and pull the files, should be in a "Stock" folder on the internal storage.
*Thanks to solarnz for these instructions
Ok, I have pulled HLK75C images which should be flashable through fastboot thanks to short/y's Rogue CWM nandroid backup. Usual disclaimers apply here, don't try this unless you know what your doing, not my fault if something messes up. That being said, download images here: http://dl.dropbox.com/u/22648028/HLK75Csystemboot.7z zip password is "AceXMachine" without the quotes. After unpacking files go to the command prompt
adb reboot bootloader
fastboot flash boot boot.img
fastboot flash system system.img
fastboot erase cache
fastboot reboot
It goes without saying that you need your xoom unlocked for this, need adb setup/working and may need to wipe data. I would do a nandroid backup of your current config before doing this. I was able to restore the "data" backup from a previous backup after restoring the "system" and "boot" from short/y's backup. Only problem I had was my market shortcut on the home screen had to be replaced since my "data" backup had the link to the older market. I rooted this before pulling these images so you should already have root when you flash this. I tested and have working WiFi and 4G with this setup. Feel free to ask questions or PM me if needed. Thanks again to short/y for his nandroid backup...even if he did make me load the Rogue recovery just so I could use it ;P

I got my Xoom back some time ago. I've been waiting to root it until it came back. (Really didn't want to go through it, and have to undo it just to figure out how to do it again)
I'm trying to find the official file from Moto for the HLK42B build that came back on my 4G Xoom. I'm on the Moto Dev site, but they only have up through the 3G upgrade listed. Anybody know where I can get the official file in case anything goes wrong? I want to make sure I have it, before I start.

Thanks for the img files. They will save many headaches for a lot of people.
It is a damn shame that Motorola will not post the updated img files though...
I've tried both Ace and Shorty's backups. They seem to work restore fine but I still can't get any 3G/4G data. I've tried both HLK75C and D. I've done many factory resets and cache wipes. I had VZW send me a new SIM card which they manually activated while I was on the phone with them and according to their end they can see my Xoom contacting the tower but there is no activity beyond that. I really never believed that was the problem since I was able to swap SIMs with my Bionic and the Bionic worked great with the Xoom's SIM (but not the other way around of course).
I'm still suspicious about the radio Baseband version. I am missing the second "ltedc_u_05.19.00" that I've seen in HLK75C screen shots and I don't have the option to select a network mode under Mobile network settings that I know needs to be checked. This makes me think my Xoom's hardware is ok since it is able to talk with the tower over the 4G modem for activation, however the OS software is not able to select the 4G radio for actual system use. Are the radio files built into the system or boot images? Where do the baseband versions listed in About tablet come from and how might these be backed up/restored? I've never really bothered flashing radios before so this part of the process is new to me. I'm really hoping this can be solved without having to return the device to Moto.

This makes me think my Xoom's hardware is ok since it is able to talk with the tower over the 4G modem for activation, however the OS software is not able to select the 4G radio for actual system use. Are the radio files built into the system or boot images? Where do the baseband versions listed in About tablet come from and how might these be backed up/restored? I've never really bothered flashing radios before so this part of the process is new to me. I'm really hoping this can be solved without having to return the device to Moto.

This is my same exact problem. Can't seem to figure out the baseband problem.
I wonder if anyone has contacted Motorola regarding a way to flash the baseband to the LTE 4G version?
Hey guys. Been going through the same ****. The MEID/ESN changes with LTE upgrade. Adds a 01 or 02 to the end of the ESN. If you downgraded and took updates, it modified your baseband, taking out the LTE part of it. If you go back to HRI66 and do the CDMA activation thingy, you should be able to re-activate on 3G. Yeah, it sucks, but what else can we do? We need that OTA to re-flash the LTE baseband.
You can get the hlk75c which is rooted then take the hlk75d update and reroot using the universal root method. That will put you back.

Oh, duh, it's so simple. I'll definitely be trying this when I get home from work today.
If it works - you will be my savior.
Scratch that - it didn't even reactivate my 3G.

I don't think that will work unless you open it up and physically remove the LTE modem. my understanding is once the LTE modem was installed the internal 3g modem is deactivated. Even if this did work it would deactivate your SIM card so you wouldn't be able to use LTE in the future without getting a new one. I had the idea to switch my currently useless Xoom data plan over to my old OG Droid and then wifi tether. I asked VZW about switching and found I *could* do this but going from a 4g device back to 3g would deactivate the SIM card and I won't be able to switch without getting a new one. Too much trouble in my opinion.
I spent about 2 hours in a Verizon store yesterday after 2 hours on the phone the previous night and eventually ended up with an RMA with Motorola. I'll be returning it to them and hopefully it will come back correct in about a week. Such a hassle when I could probably flash this myself if I had the right files but at this point I don't know what else to try.
Can you repost link please. I am trying to get this on a Mac running OSX and I cant seem to unzip the file. Any suggestions?! PLease HELP!!!

This does not work I've tried it a bunch of times in different fashions. I even flashed 3.2.2 then flashed the official recovery took the next update and nothing. Actually its been said that HRI66 over rights stuff that we need. Take that with a grain of salt.

Yeah, it does. The radios are in the bootloader, aka mmcblk1p1, aka the ebb partition.
Theoretically, we should be able to get a dump of the post-upgrade bootloader, dd it over our borked bootloaders and have it working. Problem is, getting that dump and figuring out how to do the flash. We definitely don't want to do it in a powered up system...that leaves recovery or fastboot.

It restores your device but it will not bring back 3G/4G. If it does please tell me how because I've flashed it a few times and it did not bring back 3G.
Actually in reading your post a few times you say it yourself that its a borked bootloader. Flashing HRI66 will not fix this. If it did we would be finished and we could close this thread.

MEID Repair

Greetings XDA,
I am not sure if this is the right place to post this, but here goes.
I received a replacement phone from Asurion, and when I went to activate it, it wouldn't activate. I took it to a Sprint Repair Center and was told that I would have to get a replacement from Asurion again. I decided to do some digging to find out why, as the Nexus S is out of stock (somehow). I booted up CDMA Workshiop, and read the MEID from the device to find out that it was all zeros. DFS Evolution also read the same information. I called Sprint and verified that the ESN/MEID on file was the one on the sticker located in the battery bay. Seems it was a mainboard replacement and the programming info was never written to the EEEPROM. I attempted to write the MEID with QXDM, and got no return in the activity log. I tried again with DFS, and got a CPS_BAD_PASSWORD error. I noticed at the very top the "password" was sixteen F's. (FFFFFFFFFFFFFFFF). I tried using the Qualcomm Universal write method, and it did not work. I also tried using CDMA Universal, wrote the pESN using the direct EEEPROM method, and it appeared to take, phone rebooted and the log said the new ESN and Checksum was written successfully. The phone rebooted and it is still all zeroes.
I know that the issue is somehow with the software, or I am not doing something right. Keep in mind I am not asking for help flashing the MEID over to some other carrier, I just want to program the phone OTW without having to wait a week or more, and Sprint already approved the ESN in their inventory. So I am almost 100% certain it is not illegal. I have done ESN repair before, but this one is throwing me for a loop. Is there some method or step I am missing? Is there actually a password that needs to be set for the device. All tools are throwing the same error in their own way, and they are all related to this "password."
Can anyone give me some advice?
Thanks,
Austin R. Stratton

Of course.
Was able to fix it. Apparently there was a 16 character unlock code I was missing. Then DFS Evolution did the rest. Everything is working now.

I know this thread is old but I just ran into the same problem what 16 digit code did you use and where did you put it in workshop
