[Q] Flashing Stock Rom

I want to flash back to stock rom 4.1(cant recall if 4.1.1 is the newest one or not) in a similar manner to how I flash to custom roms such as:
MAKE A NANDROID
Boot into recovery
Wipe data/factory reset, wipe cache, and wipe dalvik cache
Flash ROM
Reboot
I'm currently on PA ROM stable. So here are my questions
1) Can I flash like this instead of going through ODIN and losing root etc
2) Can I keep my root and flashing this like a custom rom, but in actuality a stock rom
3) If this is possible can ATT stock rom work on Roger's i747m, i suspect it would as long as i dont touch the modem. Not sure if there will be LTE issues.
I couldnt find anything on XDA or google, it seems that all stock revert it to original setting and no root.
Thanks

Really could just move media and photos to an ext sd card and Odin a stock rooted 4.1.1 ROM.

Well i must hang my head in shame for not being able to find this.
This is a good way of flashing a "custom" stock rom without odin and keeping root.
Have you heard of any issues (LTE or any other) with ATT stock on Canadian i747m?
THanks

You'll have to flash the stock for your carrier if you don't want issues.

It's just that I noticed this part of the forum referred to AT&T, Rogers, Bell, Telus, I wondered if they would be interchangeable.
A lot of the ROMs out there like CM10 and AOKP support ATT but can be ran on canadian i747m's, so thats why I was wondering if ATT stock can run ok on i747ms
EDIT: in beerdroid's link he did enter "**WARNING!** All information and attached links are for the I747 and I747M ONLY!"........so I'm going to assume that the ATT stock rom can run on i747m's without issue.

I think it would be for the most part, would just have to change the modem (I think?).
Either way, always safer to go with your carrier's.

Good find. I had forgotten about that one.

Typically, if you flash an att modem on a Canadian phone it will destroy the imei. I would think that the same would be true for Canadian modems on Att s3's.

[Q] N7105 4.3 ROM on i317

I found a HK 4.3 ROM that I would like to use in my i317. However I am not sure how to start. Here are what I have tried:
Flash it directly in ODIN would result in a fail right at tz.
I am also not able to fully cook the rom, as Linux Reader cannot open the csc_cache file converted (red with a big question mark), so my rom is left without CSC.
Without CSC, I am able to create the custom rom, flash it, update modem to MH3. Using bootloader without KNOX (4.1.2), with a custom wifi fix kernel (for all other phones except i317) I found in this forum. Technically the rom works, but I don't feel very comfortable on using it.
I am looking for some input here. Thank you.

This will not work. You will need to go to the porting thread in the dev section for this. Don't try to flash a rom from the 7105

I have successfully cooked N7105 rom for use with i317 before, with 4.1.2.
My main concern at this moment is how I can deal with CSC, since Linux Reader is unable to mount any of the csc_cache.img.ext4 (the 1.4GB file from the 20MB cache.img) converted from 4.3 ROM. Have tried 7100 and 7105 and it cannot be mounted.

Update:
I am now able to grab CSC from both ROM and cook in Kitchen. However:
Using stock N7105 MK3 CSC, no matter what modem I use, baseband is always unknown. And the device is not so smooth.
If I extract AT&T MJ4 CSC, I can get everything working EXCEPT mobile data. The Mobile Network State always says "Disconnected" even "Mobile network type" shows LTE and I have the correct APN (from AT&T's CSC).
Scratching my head on this.

[Q] How to 'debrand' the SGH M919?

Hi!
I got a SGH M919 (T-Mobile Samsung Galaxy S4) and I just can not find a stock Samsung ROM for it.
How do I debrand it and bring it to a non-branded version of ROM? I don't prefer custom ROMs so, is there any stock Samsung ROM out there which I can flash on this to get rid of the T-Mobile branding and all its apps?
p.s. I am not sure if this question has been raised before because I browsed through the forums but could not get an answer.

Short answer, yes. You could flash the international I9505 firmware. Just make sure modem and kernel is that of tmobile.
Yes the question have been raised before.
☞ Sent from here☜???

Hey, thanks a lot for the reply!
3 questions:
1. Wont flashing the i9505 firmware brick my phone?
2. How do I use tmobile kernel and modem? Im an uber noob at this so dont know how to do this. Is there any thread on this topic?
3. I have currently unlocked my phone to work on non-T Mobile network with help of a thread I found on xda. Will flashing firmware for i9505 make it locked on tmobile again?

1) i9505 has the same hardware as the m919 so flashing the firmwares won't brick your phone. The radios, modems, etc, those are all different, which is why you need to flash a T-Mobile kernel after you're done flashing the i9505 firmware.
2) You are already on the MK2 modem/bb. You can flash one of the MANY kernels available. Check here and look for the threads that have the [KERNEL] tag in it. Simply download one of them to your phone, go into recovery, click on "Install zip from sdcard" and click on the file you downloaded. Most of the threads have instructions on how to do it if you're not too comfortable.
3) No, unlock is not firmware based. Flash any roms you want, just make sure you flash a tmo kernel afterwards.
Good luck and hope that helps.

Worth noting; whatever ROM you decide to flash, make sure you use a custom recovery to flash and not Odin. The Odin images for other carriers will likely brick the device because they come with the modem, radio, etc.

Thanks a lot! Will make sure of that. Just for my knowledge: I downloaded a carrier-free ROM from samfirmware (I9505XXUEMKF_I9505AUTEML1_AUT - Switzerland) and was going to most likely use CWM to flash it on my cell - will I have an option while flashing to not flash the modem, radio, etc.? Or when I flash, the modem and radio etc. will not be getting flashed automatically? (this might be a dumb question so please bear with me!)

You won't have to worry about it if you're installing the ROM by itself. It won't be affected. As long as you just install a Tmo kernel and the ROM of your choice, you'll be good. The modem and etc are separate unless for some god awful reason the Dev decided to throw it all into one zip. I have never seen this nor do I think it even exists. When installing the ROM you won't have to worry about the modem. Dude, just make sure to do a backup and you'll be fine. Good luck

If the file ends with tar.md5 it's an Odin package and should be avoided. If it ends with .zip though it's CWM-flashable and, speaking for XDA's ROMs, won't include modem, baseband, bootloader, etc.

I actually prefer stock samsung ROMs over customs ROMs so I downloaded the one I mentioned from samfirware.
Now as for flashing a T-Mobile kernel is concerned, I was going through the kernels on xda and they all seem to be custom with tweaks done to the hardware clocks, etc. Is it possible to flash a 'stock' T-Mobile kernel on the 4.3?
Btw, I am not able to flash the stock ROM (in .zip format) that I downloaded from samfirware using CWM. It gives me this error: "Installing update... Installation aborted." How do I flash a stock ROM downloaded from samfirmware (using CWM)? I am being advised not to use ODIN (due modem etc issues), so what do i do? I reiterate, i don't prefer the custom ROMs.

Samfirmware downloads are in zip format and you have to extract them to get the .tar.md5 file. That .tar.md5 file HAS to be done through Odin. You can't use those in CWM. The CWM ones are the ones you find on these forums.

The point I'm trying to get across is to not use Odin to flash anything that's not specifically meant for your device. It looks like he's trying to use the stock Odin-flashable firmwares for the i9505 which would be bad... Any of the CWM-flashable ROMs in the i9505 (not i9500) are good to go.

You are absolutely correct. I don't think he understands the difference between the two... :crying:

Um, guys, my question still seems to be unanswered: since samfirmware roms are not cwm flashable, WHERE do i find non-odin flashable stock rom? Is it even possible? I downloaded samfirmware stock rom because of the very first reply to my thread which mentioned it.
And my second question: is there a stock t mobile kernel i can use instead of the custom 'tweaked' ones?

Forget about the firmware you downloaded from sammobile it will brick your device go to the i9505 section here in XDA and download one from there and then flash it in CWM then the Tmo kernel and your done.

Looking for a wind 4.3 modem

I have a wind t889v, I am stuck on stock after taking a 4.3 OTA update, i rooted and flashed the 4.1.1 modem from here http://forum.xda-developers.com/showthread.php?t=2061031 so that i could unlock my phone, but now I am stuck with this old modem since there is no link there for the 4.3 version. Does anyone have a link to the wind t889v 4.3 modem?
EDIT: I am going to try flashing a stock 4.3 wind rom for now, but how can i upload files to my phone? I have installed kies and kies3 but neither seem to detect it, and windows explorer does not show my phones storage. I have had to transfer files through my mega cloud folder in order to get them on my phone, but that is going to be a pain in the ass for a 907mb rom...
And my next question: How do I know what roms are flashable for the t889v after taking that stupid 4.3 update? I found this guide but its for a verizon note 2. I am rooted and I am hoping there is some customized odin flashable firmware for me

all roms are flashable while on the 4.3 bootloader. you will need to install a custom recovery (CWM, TWRP, etc). here is a link to the modem: http://forum.xda-developers.com/showthread.php?t=2554226 you can flash this in said recovery

Oh alright, I suppose I can give it a shot. But I have been told its not possible to flash anything other than stock factory 4.3, for example here:
Baenwort said:
If your phone has factory 4.3 you can not downgrade to a lower version as the KNOX functionality that is built into the 4.3 bootloader will prevent the flashing of a prior version.
You can still root with stock factory 4.3 but you'll need to either trip the KNOX counter or use one of the more involved methods. Is there a reason you are trying to flash such an early version?

what that is referring to is the bootloader. which currently can not be downgraded. install a custom recovery and you can flash rom zips not images. most roms do not have a bootloader in the zip so there will be no conflict

N7105, i317, and SGH-T889 ROMs are usually OK. Don't flash another device's modem. There is a whole mess of ROM options out there.
Make certain your APN is correct in other carrier designated ROMs. Don't flash recovery from automated recovery installers as they will not put the correct version in unless you are on a ROM with the correct build prop settings for the SGH-T889 (if your using a Tmo US device).

I was more referring to ROM Manager and Goo Manager. ROMs that flash modems are atypical. Usually they leave you with a choice to install one of a couple choices or leave it as is. Sometimes they don't.
You may be able to find the 4.3 modem appropriate to your device around here somewhere. That will work much better than the 4.1.1 if you can get it to stick.

You could mobile Odin the stock image from sammobile or the root66 to flash everything but the bootloader. Kies recovery could maybe work. T889V is stubborn with modems IIRC. Teshx had problems with this very problem quite sometime ago IIRC.
This fits in my "this is a problem" category, backup and save your data.

yeah i did some wiping in recovery and managed to soft brick my phone, then using pc odin to flahs a stock image got my phone back to life and showed signal bars again, then i flashed the custom recovery back on. so at least i know i can save my modem when i do this again. i then tried replacing the modem.bin files in the dn3 istall zip with t889v modem.bin files, tried reflashing it with the new modem.bins but it still gives me the no network symbol instead of signal bars.

Data drops occasionally

My data still drops on the new 4.4.2 kitkat update on m919. Like always airplane mode solves the problem. Is there a fix for this?

That does not resolve the problem, the problem is the 4.4.2 kitkat and 4.3, Im having that signal issue also, and I have tried other firmwares. I also have a Note 2 and when it runs 4.1.1, this version has no issue. The new firmware with the modem inside it, its what causing it the problem. Your best bet is, as I have posted in a few section is for someone to make a back up copy of the QCN, of the original stock M919V modem file QCN, its very easy to make a backup of the QCN, with that we can reflash it in QSPST and make the AWS work, I need someone here with a videotron s4 model M919V to make a backup copy of the QCN file so we can try it out, if not we need to wait till they release a newer version. My model is the S4 but my model is i337M, but you can flash the M919V firmware because its the same modem inside it, NE1.

Your best bet is, as I have posted in a few section is for someone to make a back up copy of the QCN, of the original stock M919V modem file QCN, its very easy to make a backup of the QCN, with that we can reflash it in QSPST and make the AWS work, I need someone here with a videotron s4 model M919V to make a backup copy of the QCN file so we can try it out, if not we need to wait till they release a newer version. My model is the S4 but my model is i337M, but you can flash the M919V firmware because its the same modem inside it, NE1.

True still happens with nb4 modem. I want to go back to mk2 since I got better signal speeds. Can I go back from nb4 to mk2 again ?
