[Q] Baseband relationship to a (Stock) Rom - XPERIA X8 General

Hi, I want to flash my X8 with the SE stock rom "X8_Shakira_E15i_2.1.1.A.0.6_generic.ftf"...
My current system is below:
E15i
Version: 2.1-update1
Baseband: xxxx06
Kernel: 2.6.29
Build: 2.0.1.A.0.47
Will the update change the baseband version? And what effect does the baseband have if modified? Would this prevent me from rooting and installing xrecovery?

If you flash newer ROM without flashing higher baseband you may have connectivity issues (like broken internet connection), so it's highly recommended you flash both. And no, it won't affect things like rooting, xrec, or anything like this.

Cheers, okay. Do I need to backup the baseband somehow before flashing the new one? My thoughts are that if I ever have to return to the old rom there may be a compatibility issue or is it a non-question?
Btw, I xrecover'd the new rom and all is good...
I intend to flash the baseband later in the day.

Q: I can't flash from recovery, I get an sdcard mount error.
A: It seems to be related with phone's who are using version 2.51. To solve, try to flash any recent SBF file. If you want to do a nandroid first, check if SD Recovery works for you.

So the SDcard problem seems to originate from the version. The solution which has been provided is to flash any recent SBF file. This is where I am stuck at present.
1)What SBF file is recommendable?
2) is it really required to do take a nandroid image?
Perhaps something to mention: I am working without phone SIM and with a 2 GB Kingston SD card.
Flash a froyo ROM, root and instal 2nt init. Best a non blur ROM (then you don't have to register)
If you don't want to go to eclair (void warranty, official upgrade for your country) you don't have use nand. Nordic is a good choose.

Hi,
thanks for the reply, greatly appreciated. No, I don't want to go back to eclair, since I do not have any warranty anymore....
Where can the ROMs be obtained? I stumbled onto the website as provided by Moto defy a beginners guide (grrr, I cannot provide URL's here) where a whole list of SBFs are given.
However, Nordic seems to be a Gingerbread SBF? Which one to pick in order to get CM working?
Thanks! TY
Problem has been solved.
I updated the phone with Motorola update manager to version 2.2.1.
After the update, the installation of CM worked perfect.
Regards, TY

[Q] I9500 Camera Issue and Installing ROMs of Other Countries

Hello,
I am quite confused by the fact that there's way too many stock ROM versions out there, each one seems to be targeting a different country and with no obvious changelog. So my two questions:
1- Has the camera issues been fixed any available ROM and/or kernel? Stock or modified. By issues here I specifically mean the lag when opening and the fact that it will crash the system if you have more than 4 processes running.
2- Can I install any stock ROM on my device? I mean different countries or cryptic symbols like "open CRM" or "German DMT" or stuff like that. If the answer is yes, is there anything special I should backup? I read about having to backup something like the IMEI or else the mobile data won't work. I am familiar with TiBu and doing Nandroid backups, are they enough?
I have an I9500 I got from Egypt, running stock ROM build number: JDQ39.I9500XXUAMDK and kernel version: 3.4.5-526212.
I am sorry if there is any common sense I seem to be missing, I tried my best searching before posting. Thanks in advance.

I was living the same situation as your with the camera having the MDK FW version.
The simplest way to have the better camera working is to upgrade from this buggy MDK firmware to any other upper, MEA the fisrt.
Choose region close to your in the stock availabilty at SAMMOBILE site, or go to a custom rom. They are "few" available in the dev section and they are all about good.

Thank you a lot. But what about the IMEI and CSC? Will it just work if I flashed a stock ROM via ODIN or the modem won't work because it's a different country?

Sure the CSc will/must change but it has little importance, you will be updated by Kies (if you want follow this way, according your new CSC.
MODEM and IMEI are not modified 'hopefully' with this update.
From my side I flashed wananlite 1.8 custom rom that is complete with stweaks included for sound modification and will never come back under KIES hook....
your choice is up to you, if cautious read some other threads giving all explanation and learn to get skills!

[Q] Is baseband and kernel and android version important when flashing ?

hello,
When flashing ROM should we check previous OS baseband, kernel version and androidn version ?
I heard from my friend that you cannot flash older andriod version on previous version such as installing 2.3.3 on 4.1.2. Also, he said that baseband much match the new ROM otherwise the phone will be bricked. Is this true ?

Your mate doesn't know much. You can flash any firmware, old or new so long as it is for that phone.
You can also mix and match modems and kernels, also so long as they are for that phone model.
No phone I know of has gone from 2.3.3 to 4.1.2 unless the 4.1.2 was a custom firmware. Even so you could still flash it back to an older firmware in odin or even cwm recovery (depends).
It's quite rare that a modem will cause a problem but it has happened. For instance on the S3 the baseband was updated at one stage, so that using an older baseband on newer firmware resulted in no outgoing call sound. But that was an easy fix. Just needed to relash a newer modem.
I only know of one instance where flashing a certain kernel on a certain rom caused a complete brick. That was on the S2 with one firmware version I believe.
Finally, if you are thinking of flashing and don't have much experience, my advice is read read read until your eyes burn. This forum is a good starting point.

Samsung S4 Modem Help

Hi, i need help choosing a good modem. I am currently using my samsung s4 on the o2 uk network. I dont know much about the right modem.
But how can i find the latest modem that is designed to operate on a uk network?
any help is much appreciated.
What's wrong with the modem firmware that is currently on your S4?
Under ordinary circumstances the modem firmware is only changed when the ROM itself is changed. For example, an OTA update to go from Android 4.4.2 to Android 5.0.1 would include a new modem designed for Android 5.0.1. The only time the modem firmware may need to be changed outside of an OTA update is if the device is rooted and the user is installing a custom Android 5.x ROM. This is because custom ROMs do not include updated modem firmware or bootloaders. In that case the modem would be updated manually using the Odin software.

thanks for responding,
Before i flashed my phone to a custom rom the signal i received was very good. however, since i have flashed a few roms along with their matching baseband i have noticed that the signal is not as good as it was before the phone was flashed.
i can only assume that i have changed a baseband to one of which is not suited to the uk networks, if that is a possibilty. i was wondering which baseband would be best suited for a uk network?
that is if not using the correct baseband can cause signal issues?
The correct baseband for your device should be I9505XXUHOB7. If that isn't what you're running you can download it from the baseband thread in S4 General and flash it through Odin. If you're running something later than that though, I wouldn't bother changing it. For example, my I9505 was originally on O2 before being unlocked, and it's using a later baseband, I9505XXUHOF2, which happens to be from the unbranded German ROM. I'm having no issues using it on Straight Talk here in the United States.
While updating the baseband can help, you might also want to investigate whether the ROM itself might actually be the source of your signal woes.

Im currently running the 4.4.2 XXUGNK4 goldeneye rom. would it still be ok if i went ahead and flashed the I9505XXUHOB7 along with it considering that is a lollipop version of the baseband?
In that case you'd want to get the latest Android 4.4.2 baseband possible from the aforementioned thread and install that. You'd cause more problems if you tried using the HOB7 baseband while still using an Android 4.4.2 bootloader.

thanks , ill try that now.
a little of topic is it possible to flash a lollipop bootloader and then revert back to a bootloader designed for the 4.4.2 kitkat roms?
You'd have to try it and find out. I do believe it's possible since Knox is in both bootloaders, but I haven't had a reason to test it.
