Hi,
I'm assuming the following:
The A510* and the A5100 (the dual sim version) seem to be pretty identical according to their hardware specs.
The only hardware difference seems to be the slightly modified plastic tray of the A5100, which gives place to a 2nd SIM to be put in instead of the external sd-card.
It's seems only a plastic difference, as even the A510 has the right pins at the right place to possibly read a 2nd SIM.
Question is: How can I make the A510 register and make use of the 2nd SIM?
Would it be too weird to try to flash a A5100 stock rom onto the A510?
Should it be a 4file repair image, including re-partioning? What are the risks?
Which preparations would be necessary to prevent ending up with a brick?
Thanks for input, bibbbs
I thought the A510F is a dual sim phone? The sim 2 slot is also an sd card slot right? So maybe you insertrd an sd card in already?

The A510F is sold as non-dual-sim. Only in Asian markets they sell the Duos-Version A5100. Since the A510F sim tray lacked the small spacings to hold the 2nd SIM (but the phone's not lacking the PINs!) I've bought an A5100-sim tray. But after inserting 2 SIMs nothing like multi-sim control showed up in the OS/settings. That lead me to the idea that it would be only a matter of the right software ...
The A5100 stock rom has another PIT layout than the A510F.
Before I try to flash I'd like to do all it needs to happily go back to a working A510 stock in case it fails.
Do I have to root the phone first to make an backup of any unique EFS data or so? Or will that not be affected by flashing with repartitioning?
Btw, do dual-sim phone have two IMEIs? If yes, than I'm afraid it could be more complicated ...

The specs page says that the a510f has dual sim? And yes, dual sim phones have two IMEIs.

I have been trying for the last few hours to get my UK Moto X Force to accept a dual sim configuration to no avail. I have listed the different methods I have tried below hoping that someone can identify a solution.
1st Method:
Rooted my phone and used the instructions for the Moto X Play variant to enable dual sim functionality as listed here: http://forum.xda-developers.com/moto-x-play/help/enabling-dual-sim-single-sim-devices-t3225546
I followed this method through by adding the several lines of code to a local.prop file and rebooted. The phone now had access to the Dual Sim settings and identified my 1st SIM within the phone but not the 2nd. Where it said 2nd SIM 'No Sim Inserted'. I tried with multiple SIM cards and the same error popped up, there were no issues with the sim card touching the connector plates for the 2nd sim as they had scratched the card, a visible connection had been made.
2nd Method:
I installed a Mexican Dual Sim variant of the OS and inserted both cards. Bluetooth, WiFi and Mobile connection were not working however the Dual sim menu was available. I then flashed the UK modem onto the phone which fixed the WiFi and Bluetooth not working as well as the mobile connection. However once again only one of the sims worked and slot 2 was labelled as being empty.
Any suggestions on what to try next would be appreciated to get the dual sim functionality, functional!
Thanks
I think that UK edition doesn't really have hardware required for dual SIM. Tray is just generic for all Force variant.
Actually both of your attempts proved that. I would like to be wrong in this case
Any ideas?

Need to try. The files in the fsg folder are different. I did not succeed, but it should work, if someone seriously takes up this issue.
Has anyone got the modem files to flash?
I've mistakenly flashed the Brazilian rom on mime and lost wifi
While disabling an ATT lumia 640 I found that there is a second sim card slot. Found that Tmobile MetroPCs all have the second sim slot. A separate plastic named "sim locker" is used to block the place which can be easily pushed away. On the motherboard i see the sim connectors are there. I am unable to upload the picture of the 2nd sim slot as i am new here.
A simslot can be easily soldered in there. I also learned that a dual sim firmware may also be flashed from here http://forum.xda-developers.com/windows-phone-8/general/brand-att-lumia-640-lte-t3294971
I was wondering will it work ?
Need to flash a 2nd IMEI though.
im new to windows but how do you plan to flash a new imei you can restore it but how flash it is it done using the same imei as the previous

broke my old sm-g9oop doing some home repair. (learned alot though..). Got a new sm-g900p with software version--G900PVPS3CQD1
Hardware version-- G900P.04
android version-- 6.0.1
security patch lvl-- April 1, 2017.
And of course I am rooted. I put the sim card from my old sm-g9oop into my new sm-g900p, stayed with the same carrier, Sprint, and am getting an invalid sim card message. I was told by the Sprint operator that the old sim cards are not compatible anymore with the newer sm-g900p's but he did not sound 100% sure. The phone is activated and operating but would like to get LTE, which is enabled from what I can see. I can access all the hidden menus, but am not quite sure what to mess with. I know just enough to be dangerous, lets put it that way. I have backups in case i screw something up. Was on RR remix for a bit since i had that on my old phone but couldn't figure out how to get access to those hidden menus so i went back to the stock ROM and rooted it. Is my sim already unlocked? why can't i connect to LTE? If this has already been discussed somewhere else then I am sorry for the redundancy. I've been trying to find something matching my exact scenario for a week now and decided to finally just start a new thread.
It's because your model of phone only works with specific LTE bands. And there is a way to open all the bands but it's not easy or fun. If you want more info go here

I would like to resurrect my old i9505 with Lineage but ran into an issue. I flashed TWRP (Odin) and then installed Lineage after formatting. The phone seems to be working fine except that it does not detect the sim card when I put one in. Unfortunately, I did not try the sim before flashing nor did I make a backup, so I am not sure if it was working on the original stock build, however, it was working a year or so ago when I last used it with the original stock (Android 5.1) build. Here are the symptoms:
Grey card with line through in OS
No changes at all when SIM is Inserted
Preferred Network just shows "Invalid Network Mode (-1) Ignore
IMEI is showing correctly
Here is what I have tried so far:
Replaced the SIM tray with new hardware
Reverted back to latest Stock (SIM not showing under stock)
Tried both Lineage 14 and 13 versions
Have tried flashing 3-4 different recent versions of the bootloader and modem files:
Have tried messing with the *#*#4636#*#* settings
Have re-installed TWRP, Lineage, Stock several times
Here is the current setup:
OS: Lineage 14.1 (latest version for I9505)
Baseband: I9505XXUHPA1
Anyone have any additional suggestions or any way to determine if this is hardware or software issue? I assume this can't be a carrier (locked) issue since it is not detecting the card at all.
If stock also does this then it heavily suggests a hardware issue.
How many sims have you tried with the same results?
Have you tested if microSD is working?

This problem is almost certainly a hardware issue in that the SIM card tray has likely failed. The good news is that replacement trays should be relatively inexpensive on Amazon, and from personal experience easy to replace. Just make sure to re-use the foam pad that sits on top of the connector on the original tray, as the phone's back presses down on that pad, preventing the connector from moving while in use.

I have only tried the single SIM which is working in several other phones, but I will try different SIM today. Good suggestion. Maybe the carrier chip is not lining up right or something. I will let you know if it works.
The micro SD slot is working fine.

I didn't see that in his post.
Hi everyone.
I have a problem with a Samsung S4 GT-I9505 which I bought as used. The phone came with stock rom, and with baseband I9505XXUHOJ2.
Then I updated it to the latest stock rom for my country, which is I9505XXUHPK2-ITV, with Odin. After reboot and factory wipe everything, the phone info shows build LRX22C.I9505XXUHPK2, but baseband is still I9505XXUHOJ2, which according to letter coding, should be previous.
This phone does not register SIM, nor see the SDCARD. Thinking it was damaged, I even changed the sdcard+sim slot with a new one, without success. I suppose the baseband may be the cause of missed SIM registration to the network.
What do you think is preventing the baseband to be updated? I'm out of clues
Never mind. I finally updated baseband reiterating Combined Modem+NON_HLOS flashing. However I did not solve the problem with SDCARD and SIM

Hello,
Check my S4 Unified Collection & Guides and follow the steps of the Guide Clean Install Official Stock ROM.
Sir, I followed your guide step by step. Now I have Stock-rom XXUHQK1, and the same for the baseband.
Unfortunately, the SIM and SDCard is not detected. I think it's an hardware issue. I have other S4 I9505 phones and they behave differently than this one.

If that is the case, it's relatively easy to replace the SIM card tray, provided the part is still available for purchase from Amazon or similar sites.

As I said in the first message, thinking it was damaged, I even changed the sdcard+sim card tray with a new one, without success. So the problem is not the card tray afaik.
When you swapped out the tray did you transfer to the new part the foam pad that sits atop the connection to the motherboard? If you didn't do that, you will have problems, especially the SIM not being recognized.
However, the foam doesn't result in an immediate disconnect but a gradual one. So, we have a few different possibilities here.
1. The SIM itself is damaged.
2. The device was unlocked by its previous owner using a service menu exploit, and when you restored the firmware you wiped the exploit.
3. The EFS partition is corrupted or lost.
The first can be easily tested.
The second? I ran into this exact issue myself: at the same time my SIM tray failed, which made resolving things challenging. It can be remedied by downgrading to an Android 4.2.2 ROM and running RegionLock Away by Chainfire.
The third? That one only Samsung can help with, as the EFS partition stores the IMEI and NV RAM of the S4, and unless you ran Wanam Partition Backup beforehand, there's no way to restore it.
With the premise that my problem is not limited to the SIM, but involves also the SD Card which is not detected when inserted, let me reply to your points:
1) The SIM is good and valid, as it registers to the network in another S4 I9505 which is fully operational
3) Before upgrading, I installed TWRP and made a backup of EFS partition. After checking the new EFS partition with the old, there are no differences beside a few bytes here and there, however nothing which reminds me an IMEI (they seem more like file date updates in filesystem)
2) Can you be more specific here, I never heard of this before. The previous owner, once contacted said he used this phone as daily driver until 2018. He live in my same country, and the stock firmware should have nothing locked or needing an exploit. Again, provided this would prevent SIM from registering, do you think this could also influence SD Card too?
I'm more and more concerned that the problem is hardware related. Pressing the SDCard slot connector to the mainboard, like other users have reported successfully, didn't change anything. Maybe the mainboard isn't giving the SDCard slot the correct powerage. I have seen on eBay other mainboards sold as not working with this very same defect, wifi working and SIM not registering.
