I looked around the internet a lot and wasn't able to find any useful information about this. I have a GT-I9300
I've recently updated my OS (lineage 4.1 - Android 7.1.2) and modem (I9300XXUGMK6) and I'm wondering what a recommended boot-loader might be. I chose this modem because it was listed on the ROM page, and it seems to work fine.
I found this but it appears to be very old:
https://forum.xda-developers.com/galaxy-s3/general/ref-galaxy-s3-stock-kernel-bootloaders-t2189063
Before I updated, my modem was version I9300XXEMG4, and I'm pretty sure I updated my modem and boot-loader at the same time previously, which leads me to believe my boot-loader is probably XXEMG4 too (assuming that exists).
Should I update to XXEMG5? Should I try to find the boot-loader that corresponds to my modem (XXUGMK6, assuming that exists)?
I just want something that is probably going to be reliable, not that I have any specific problems, but I believe in staying up to date. Where can I find the latest boot-loaders? Any reason not to just get the latest? What are people here using in general?
The bootloader doesn't need to be changed and you cannot downgrade once you've updated the firmware to mk6 unless you have a backup of your efs from before mk6.
If it ain't broke..

Ok, it seems to be running fine since I upgraded the modem. Thanks.

I have a firmware question that I can't seem to find the answer to by searching. I am running arhd 11 on an att HTC one. Should I upgrade the firmware on my phone? Will there be any benefits to this since I am on att and not international? Also how do I go about updating the firmware and does it wipe the device? If I should upgrade, what it's the version I should download? Longtime Samsung user so please excuse the noobness.
If alls running well, then plz avoid ... however, in ARHD thread many AT&T users have updated the firmware without any side-effects
Best to post Q in that thread itself

It is currently not mandatory to flash the new firmware for ARHD, but it does provide a noticeable increase performance depending on the current firmware version you are running, I was running 1.26 on my AT&T m7 and the screen and touch buttons have been much more responsive now that I am running the new 2.24. Flashing the new firmware will also update the baseband, providing you with the latest radio (but performance of this will vary from region to region.
If you go to this link, it will give you some great instructions on the update process.
http://forum.xda-developers.com/showpost.php?p=42556698&postcount=24958
BTW, you will need to be s-off and change your cid to 11111111. As long as you take your time and follow the directions completely you will be fine. If you do update make sure you flash the firmware TWICE when it says to, and make sure you re-flash your custom recovery because it will get replaced during the updating process. This process will not delete your sd card and you will be able to run your current ARHD, but it is recommended to do a clean install after. And you might as well since 12.0 is out.
hope this helps
I'm getting a failed not allowed error when trying to 'fastboot flash zip'
I successfully have s-off and changed CID but can't get firmware to flash
Edit: not sure what happened but I was able to push the zip successfully. Maybe from adding the path of the file instead of just the zip file? Anyway, it worked.
Sent from my HTC One using xda premium
IF the rom is tweaked right theres no real reason to update the firmware to euro build,Id wait till att variant or the dev variant gets the update and then worry about it.
I am going to flash the firmware on my m8 to upgrade to 4.4.4 ARHD but I am still unsure of how to identify the proper firmware zip . Could someone provide some guidance? Attached are some images from the recovery. I'm not sure what numbers I need to match with the firmware zip. And I can't find how to view what numbers are in the zip. Any advice is very much appreciated.
hboot 3.16 corresponds to firmware that deployed with 1.x software. Its what many folks call "1.x firmware" for lack of any better title, since firmware doesn't really have a "number".
If you want to update to the latest ARHD, you need "3.x firmware". Any firmware with number 3.xx.xx will allow the phone to boot normally, and with working WiFi. The numbers after the 3 are just carrier/region specific versions.
But for the AT&T network, you are probably best off flashing the 3.28.1540 firmware posted on WNC's ROM here: http://forum.xda-developers.com/att-htc-one-m8/development/att-4-4-3-2-22-1540-3-debloated-sense-6-t2837365
Thanks a lot!

So even if you just want the new Firmware, you have to do everything in that thread? I'm asking because it shows installing a ROM then doing stuff with Xposed, which I assume will be undone when the ROM changes

No, you just need to perform the steps listed under "Updating firmware" numbered 1-8. And also skip the very last step (Step 8, Substep 3).
The rest is if you want to run the modified Dev Ed ROM, as you have somewhat already figured out. But honestly, if you are on AT&T's network, I would consider the ROM anyway. Many folks (including myself) get various network errors running "international" based custom ROMs; which the debloated Dev Ed ROM does not suffer from.
I've been using the pac-man ROM for over a year now, but it's a very old version, buggy and outdated. I wanted to try Kit Kat or basically just find a stable ROM, but pretty much ALL of the ROMS i've tried end up unable to find any mobile network or display the SIM card as invalid. Even when I search for networks or try to add a network manually, it still doesn't stick. Occassionally it'll even find the my local network when I go in settings and do a network search, my network being that of China Unicom, but it always results in failure to subscribe, please try again later. This has happened on a good 7 out of 8 ROMS i've flashed. The ONLY ROM i've ever been able to find a network on and thus make it usable has been the old 2013 pac-man 3.99 build. I've searched the forum and google for answers, such as flashing a particular modem or whatnot, but haven't found any solutions.
Does anyone have any ideas? It'd be greatly appreciated. I really need an updated ROM! :fingers-crossed:
If it matters:
Network: China Unicom
I've tried: 4.4.4 CM11, Stone UI hD3, Carbon KK Unofficial 2014-12, CM10.2 nightly, CM 11 M9, KitKat CarbonCN, PC Honami KK RC3, and Xperia Z Z1-1.4.
Only working ROM so far: pa_togari-3.99-RC2-20131104
To use the more modern ROMs you will have to be on a 4.4.4 FTF or you will get baseband issues ie SIM cant connect to network etc

It's been over a year since I unlocked and flashed my phone, and I haven't done any flashing since, so I kind of forget some of the procedures and technical aspects.
I'm going over the FAQ now, and one thing it says is "Never Flash a FTF to a ZU GPe." What is a GPe, and how can we make sure we are not using it?
It also mentioned I should use Sony PC Companion to update to the newest firmware. This means it will update to 4.4.4 FTF right, or do I need to find this and flash it manually? Likewise, after I'm on 4.4.4, I assume my phone will be reverted back to stock. Would I have to root it and unlock the bootloader again?
I remember when doing all this for my phone the first time, since my phone was a Chinese model, 6833 I believe, I went through hell and back for several weeks until it flashed and took the current ROM properly. Something about buggy firmware in that paritcular model, although it's been so long I forgot all the details. I'm worried that I'll run into a similar situation with 4.4.4... Thanks for any help, truly appreciated.

I tried to update to KK via Sony Pc Companion, but it says my phone is up to date. I assume it says that because it's not seeing any official firmware, due to the flashed ROM. Even when choosing the option to "repair my phone" which says it will re-install the latest available firmware, it states that there is no software available for my device. If memory serves me correct, I must first flash back to my oldest stock firmware that came with my phone, then I can use PC companion to update to KK, and then maybe unlock bootloader and root again, and then I'll be able to flash new ROMs and have a working mobile network, does that sound right?
Out of curiosity, since it's 4.4.4 ROMs that don't seem to work (network wise), doesn't that mean 4.3 ROMs should find a network just fine?

I cant remember where/when the baseband changed, it has been updated several times. I would just go straight to 4.4.4 and not worry about PC Companion - Just use the latest flashtool (http://flashtool.net).
Grab a 4.4.4 (aka x.x.x.108 or .118) FTF from the FTF thread in the dev section and flash that. That will wipe all user data (so back it up) and install a new /system image. You will have to root the device again abut 4.4.4 is easy to root now with the easyroot tool. Then you should be on the latest baseband and all the new ROMs should work - 4.4.4 and 5.0.x
Thanks blueether, I'll give that a go and report back (hope you don't mind). Here's hoping (since i know the 6833 chinese model is finicky)...

You mentioned I should get a *.108 or 118 in order to get the ROMs working again (mobile network wise).
I found in the FTF repository: STOCK ROM] [FTF] Xperia Z Ultra 6833 14.4.A.0.118 "VodaFone UK" and also "SRF FR".
I'm using a 6833 in China, however. My guess is these wouldn't work because they require different networks.
Doesn't matter? Or perhaps, I just flash any 118, and that will give me the newest firmware. Then I can flash other ROMs (that use the same firmware), which will have updated modems, and consequently get my network signal back. Is this how it works? Want to be 100% sure before I go flashing with firmware that would make my phone unusable. Thanks for any advice!

any 108 or 118 for the c6833 should work just fine
If anyone has a stock sch-r530u (U.S. Cellular) firmware, that would be great! Can't seem to find it on the inter webs.
What firmware does it have currently? I've only been able to find an older version of JB - 4.1.2. I might possibly have another version on my hard drive at home but have not looked into it for a long time so am not sure...
http://teamuscellular.com/Forum/files/file/168-stock-files/
If you have already updated to 4.3, I do not think this file will work.
Hello!
First of all, I'm a novice and have no knowledge of how the firmware is constructed, e.g. wrt any dependencies between BL, AP, CP and CSC. I've searched the S9+ forums without finding answers - I have however found threads concerning downgrading but they seem not to answer my exact question.
I'm currently on the latest build of Android 10 for my region (SM-G965F, 965FXXU7DTAA). Completely stock, no modifications.
I read in an S7 thread that someone had been able to downgrade to a previous FW version with a lower BL version than the phone currently was on by doing the following:
- downloading and extracting the FW wanted
- removing the sboot and the modem parts of the firmware
- repacking the remaining parts
- flashing with odin
According to him/her, this worked, the phone booted succesfully, even though he/she at that point hadn't yet tested it to the full extent and in all aspects.
My question: Would this even be possible for the S9+? I.e. only flashing the AP and CSC parts of the desired FW via Odin while leaving BL and CP parts untouched? Would it even work, and if so, is it possible to say/know anything about adverse effects. Is the phone likely to brick? Knox?
Excuse me if this is obvious to you all, but I'm curious about this as I am currently not satisfied with Android 10.
I should add that I'm aware that it is currently possible to downgrade to latest version of Pie the "regular way", but I'm looking for options, if any, to go even further back

admittedly, i TL : DR all of it, but on the S7, downgrading the bootloader was possible for a while, thats not the case here. You can only flash F/W with the same or higher BL version. If there is an android 9 version available with the same BL, then you can flash it all you like. www.sammobile.com/firmwares is where you need to go to look. But use the frija tool or SamFirm to actually d/l the zip unless you like wasting 2 hours of your life
Thanks for the reply
I'm aware that I am able to downgrade to the latest version of Pie, which has the same version BL as my current Android 10. But my question is rather if it is possible at all to flash only the AP and CSC sections of a previous FW (with lower BL version) and leave the current Android 10 BL and AP untouched as it is on the phone?
Sorry if I was unclear in my first post

As long as the previous firmware is the same bit number you can flash either. You would have to flash all the files as the 10 bootloader more than likely isn't going to boot pie. 5th Digit from the far end of build is your bit number.
Thank you for your reply - good input wrt 'bootability'.
I'll downgrade to the latest version of Pie the regular way.
