[Samsung Galaxy S10 Questions & Answers] frdbr:
Hello guys, anyone can help me?

I bought a s10 factory unlocked to use in brazil, the first 2 days it was all fine, and then i can't get signal, or when is registered in network, doesnt make or receive calls and the internet doesnt work.

I already reseted the cellphone, tried another sim card, flash the firmware too, and nothing works. I downloaded a program called network mode to change the type of signal i wanted, and it get registered in network but no calls.

Tried set the network manually in the config, but no results. Samsung and carrier support didn't help either.

What can i do in this case? ( I already wipe the cache)

Is it true that i cannot use the ZTO firmware from the sm-g973f?

I am worried, because if nothing works, the s10 will become a brick haha.

Maybe it's because this model have the snapdragon and the brazil have the qualcomm?

My Model is the sm-g973U1 128gb.

Looking forward for an answer, tks
[Samsung Galaxy S10 Questions & Answers] johnny8910:
It is possible your sim card has failed. I had a similar issue last year.

I had to get a new sim card from my provider.
[Samsung Galaxy S10 Questions & Answers] sixline:
Well snapdragon and qualcom are same. Check your sim elso you should be able to claim the warranty.
[Samsung Galaxy S10 Questions & Answers] rodrigoger:
If your model is sm-g973U1, you cannot use ZTO firmware from sm-g973f. They are not the same. You have to use firmware from 973U1, but it should work on brazilian operators. How did you buy it? Is it unbranted or from any operator? The 973U frequences are compatible:

2G bands	GSM 850 / 900 / 1800 / 1900

3G bands	HSDPA 850 / 900 / 1700(AWS) / 1900 / 2100

4G bands	LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 13(700), 14(700), 17(700), 18(800), 19(800), 20(800), 25(1900), 26(850), 28(700), 29(700), 30(2300), 38(2600), 39(1900), 40(2300), 41(2500), 46, 66(1700/2100), 71(600).

Or the possibility of blacklist comes in my mind. If bought second hand most likely the seller reported it lost/stolen. Had the same issue year or2 back...

As it worked for couple of days then stopped, sounds like stolen.

It seems everywhere I go there is no root for this phone (sm-J337a) it's an at&t phone. I used kingoroot, kingroot and basically any root out there. nothing has worked. So this seems that it has no root made for it yet? is there any possibility for someone to do this? Sorry, I'm not too good at rooting as a whole. But I've used Odin and things like that before.

there doesn't even seem to be CWM or TWRP for this phone either.

it's running Android 8.0 and was made in 2018.

Hi all.. I know this thread is a little old but thought id add this.. As of this date Ive found no ROOT solution for the SM-J337A - AT&T variant either.. I have found a lot of other software and such and as soon as I can get it all sorted, cataloged, and uploaded to the cloud I will see about placing some links here somewhere to all of them.. Not sure how long it will be..Stay tuned...

I happen to inherit a J337A with a cracked screen but was working fine until I updated it and tryed ROOTing it.. Im still Playing with it to see if I can revive it.

Having issues finding a UB compatible Firmware set that I dont have to pay for.

Am needing "J337AUCSBBTI1" or maybe "J337AUCSABTE1" to see if I can bring it back to life.. I may end up pitching it tho...

I can help you with that if you still need it. I have my j3 rooted with magisk, although there is no twrp or any custom recovery for that matter..

I can give you the exact files along with the patched magisk file and you'll have to flash it with patched odin and you should be good. Let me know.
[General Questions and Answers] iamoz:
Yes I would be interested in having those files please... Either upload them here or I can give you an email if you prefer... Let me know..
[General Questions and Answers] NonStickAtom785:
Instead of sending a patched magisk file would you mind sending over the method you used to root? If you did what I think you did I'm very confused. The phone is OEM locked although this hasn't stopped others from accessing root before. If you can confirm you have the phone we have, the SM-J337A ATT then you can pull out the boot and recovery images using a root app. Then I could develop a working TWRP for our device. But ofc this is only possible if you explain how you went about rooting the device. Thanks in advance.
[General Questions and Answers] rip21skinz:
I have both SM-J337P/A and it works the same on both. I'm not sure why you wouldn't be able to be oem unlocked? You mean greyed out? Or does it not show up at all or what? If I go into developer options I have the oem unlock option, which then allows me to unlock the bootloader. If yours is greyed out I saw a solution on XDA a long time ago, maybe a year ago. I'd have to look for it in my files, I know I saved it somewhere. Let me know what you meant by that and we can go from there :)
[General Questions and Answers] NonStickAtom785:
I do not have the option to OEM Unlock the phone period. It is not in my developer options unfortunately. If you do find something of that nature please do contact me. Also if you would like a TWRP for your device I'd be up to developing it, although I wouldn't be able to maintain bugs... All I need is the kernel and I can get it done. :)

In my TYTN2 i instaled hardspl....but with niki i dont realy what to do!

I read a post regarding spl in this forum but i didnt understand what to do.

Thnks in advance
[Touch Dual, MDA Touch Plus ROM Development] Antubis:
Since you already have a Tytn II with HardSPL installed, I think you'll easily understand how to do to CIDunlock your Niki, so I'll quickly remember it to you.

Download the SSPL.EXE and HARDSPL 1.16 or 1.15 zips form the HardSPL/USPL topic, copy SSPL.EXE on your Nike, launch it (your device will reboot overriding the SPL), and then run a RUU with the HardSPL.nbh (I guess you know how to flash with your Kaiser).

10 seconds after, you'll have a CIDunlocked Niki on which you can flash any ROM you want ;)

[Nexus 5 General] ilciumbia:
Hi everyone!

After months and months, and countless hours spent (and a good deal of destroyed Nexus 5 motherboards...) ,I have succeeded in expanding both RAM and storage of a Nexus 5!

The RAM:

I have been thinking about it for quite some time, then I decided to go for it, so I bought a 24Gb LPDDR3 memory chip from Aliexpress and attempted a replacement to my spare Nexus 5. Well, believe it or not, it worked!!! My N5 has 3 GB of RAM, and the difference, with my 242 apps installed, is very evident! It has been hard work, not easy at all, but if there is anyone who has the necessary skill/equipment and is wondering if it can be done, well, the answer is YES!

The memory chip I purchased is the K3QF7F70DM-QGCF.

Replacement requires removing the ePOP memory from the top of the Snapdragon chip, then cleaning carefully the BGA land pads from any resin/glue residue, then re-soldering the new chip. I am not going into details (unless requested) because those who know about BGA reworking know what it is all about and those who don't... Well, don't try it! Anyway, I am available to provide any further explanation.

The Flash:

Then... I could not stop there. RAM is nice, but I was running out of storage space... Plus, it seems it had been done before, even if not many details had been provided... Well, there is all sort of documentation and software one can desire for the Nexus 5... So let's go for it! Let's buy a 64 GB eMMC chip from Aliexpress and let's try to transplant it!

The operation has proven more complex than I could have imagined: I collected 13 (!) dead Nexus 5s so that I could experiment with them, I fixed some of them and then I destroyed them again in the attempt to transplant the chip! :p The endline is: "Don't try this at home unless you are willing to end up with a broken phone"! And, believe me, it is VERY likely this is going to happen!

But the screenshots speak for themselves:

https://photos.google.com/album/AF1.../AF1QipMCqe-Xn4x5l6PRykQDxyRnVhrbxZqTU0ZGumd4

If anyone is interested (be careful if you want to attempt the mod) I will provide all details of hardware equipment used, how to desolder chips, how to solder the new ones (but if you need to read my instructions then the operation is clearly out of your reach!) and how to flash the new chip with bootloader, recovery, ROM and everything. Just let me know!

Regards!
[Nexus 5 General] DarkMaxOff:
Hello, can you show in more detail and with screenshots where you soldered the memory. how long did it take you
[Nexus 5 General] MishaalRahman:
Did you take any pictures through the process?
[Nexus 5 General] ilciumbia:
Hi guys,

unfortunately I have not taken any pictures, because I had not the slightest confidence in the outcome! However, I can summarize the process with pictures found online:

1- the memory chip (which is on top of the processor) is the one with the red dot on it; you must also remove the metal shield around it, which is fitted with just clips, so a small screwdriver and some care is enough to remove it;

2. you must heat up the chip with a hot air rework station; I also recommend to cover the rest of the board with kapton tape (or, at worst, with some aluminium foil);

3- use a thermocouple if possible; if you don't have it, monitor carefully the melting of the memory chip. Keep in mind you have to remove the memory only, not the entire chip (but the memory chip, being on top, is the first thing to come off);

4- using a needle or a thin razor blade, gently leverage one corner of the chip until you feel it softening and finally coming off;

5- after removing it, you must very carefully clean the pads from any glue left on them (yes, the memory is also glued!). The pads are not too delicate, however exert maximum care, you do not want to rip any of them off; I personally used the scalpel tip of my soldering iron to clean and level the pads;

6- use isopropyl alcohol, acetone and some sandpaper or a pencil rubber to clean the pads from any dirt and oxidation; you must end with some very clean pads, as in the picture (of course pads will not be gold but silver);

7- spread some gel flux on the pads and place the new chip on them, carefully aligning it with the processor underneath (careful about pin 1!);

8- heat up the chip again with the hot air gun; look at it from the side, until you see the balls melting and the whole chip settling down in the correct position;

9- remove hot air and let it cool nice and slow;

10- enjoy! :)

Please note that the process is extremely risky and complex; if you need to read the above steps, probably you should not attempt it; but if you succeed, results are worth the effort! The whole process took about 1-1.5 hours (I do not know exactly).

Next step will be to upgrade storage space (someone has already done it, if I remember correctly)!
[Nexus 5 General] matusala:

[Nexus 5 General] ilciumbia:
I do not recommend hot air on that connector. It is very prone to desoldering, but your best bet would be a very thin soldering tip, like the Weller LT1S, for example.

As for a cheap hot air reworl station, this is a pretty standard one:

https://it.aliexpress.com/item/220V...a0-4569-8e61-9b85979280bd&transAbTest=ae803_5

or even cheaper:

you will have to build your own stand, because it is impractical to hold it in your hand (you will need both at a certain point!). I attached it to a desktop spring loaded lamp, "Pixar style" to be clear.

[Nexus 5 General] lo2ay:
It would be awesome if it worked, really awesome. But I don't think it will work right of the bat. A different processor will most probably need an update in the kernel code to accommodate for that hardware change. I think that this hardware change is significant enough to require an change in the kernel source. Same goes for upgrading the internal storage.
[Nexus 5 General] ilciumbia:
Actually, the Snapdragon 800 and 801 are pretty much the same processor with some very minor differences, so I would expect them to be swappable. The first attempt, however, has proven to be a real disaster due to the fact that all BGAs are glued to the PCB with some strong epoxy and removing them is really hard, because it is difficult to understand if the chip is holding on to the glue or if temperature is not high enough... So you raise it and raise it to the point the PCB gets delaminated... :(:(:( So I am waiting for a new PID and a new thermocouple so that I can monitor the temperature more accurately!
[Nexus 5 General] lo2ay:
Maybe you're true about the processors, I hope you are it will make it much more easier for you :D . But is the difference between them really worth the effort? As far as I remember, it's just a slight increase in clock speeds (for both CPU and GPU).

I remember I saw someone on Youtube who upgraded the internal storage of their iPhone to 512 GB, he had to create new partition tables for the new storage chip. If my brain doesn't fail me, there's someone here on XDA who also managed to do it for the Nexus 5, he also had to create new partition tables and done some flashing for some stuff that were required to get it to boot. I'll try and find the link maybe it would help you :D

I'm really interested to see how much further can you push a Nexus 5 before it reaches its limits :D

Edit: Found it! Check the thread here. It was also featured on XDA news
[Nexus 5 General] M520iX:
Ok.

Jeezus, maybe 805 and with and it is a mini Nexus 6? xD
[Nexus 5 General] ilciumbia:
Hi all,

here I am back after quite some time, to report results which are disastrous to say the least. In the past week I have collected some malfunctioning Nexus 5 (some with broken switches, other with broken screens, others with broken eMMC chips), fixed some of them and then attempted the mods I had dreamed of, unfortunately so far I have managed to destroy them all, and must conclude that my very first attempt when I successfully swapped the original RAM chip for a 3GB one has been nothing but a lucky event and that my ability to perform such mods has been overestimated.

To summarize what happened so far:

1- attempt to replace the SD800 wirh a SD801 and concurrently mount a 4 GB RAM chip has ended up with a destroyed SD801 and a destroyed RAM chip;

2- 2 attempts to replace a defective eMMC chip on a working SD800 ended up with a non functioning phone;

3- replacement of a defective WiFi/BT chip succeeded, but the subsequent attempt to replace the eMMC chip ended up with a non functioning phone;

4- replacement of RAM chip with a 4 GB one ended up with a fried SD800; unsure about the RAM chip.

I am not giving up though; I am still convinced that it can be done, and that it is only a matter of finding the right way to desolder and then resolder memory chips... I am continuing experiments and collecting cheap damaged Nexus 5 phones. If you have one you can spare... :)
[Nexus 5 General] ilciumbia:
Here I am, and this time with great news! Finally, after 13 motherboards sacrificed in the name of knowledge, I have succeeded in expanding both RAM and storage of my Nexus 5! See OP and, if interested, I am willing to provide any detail you require!

Regards!
