iPhone 5S iTunes Playback Error -1: Baseband Reballing Tutorial & Shopping List Needed

I warmly welcome,

When playing iOS on iPhone 5S, I get error -1 at the end of the process. I have already read a few threads and I will probably have baseband reballing, but the problem is that I have never performed such a procedure. I have two damaged records from 5S and 6 at home, so I could learn reball on them first before I do it in the 5s.

I have rummaged in iPhones more than once, basically I took apart every model and exchanged something in it, but I never took the motherboard and rummaged in it, but I would like to finally learn and start the adventure with repairing U2, baseband, nand e.t.c.

Could someone write me an exact shopping list for this procedure? I will be extremely grateful, unless such an answer is already in some thread, I am sorry and I will continue to search the forum.

greetings

Hello,

As for the problem of error -1, unfortunately, but the baseband is dying or has already died and when you heat it up it's over, these systems cannot be programmed and cannot be exchanged with any other similar situation with a lack of signals in the iPhone 6. Due to age these phones are already happening so that more and more of them appear with such baseband problems and no one fixes it, maybe only China is doing it by transferring CPU, baseband, eeprom and nand to a good disc here it is as no fix.

Exactly! In addition, the baseband is still glued on Fridays, so even raising it, cleaning the pads and re-soldering is already mission impossible. In sixes it sometimes helps to restore two connections under baseband.

I would also verify Baseband eeprom soldering, it's best to do reball. The content of the baseband eeprom often flies. Sometimes Baseband power supply. However, the most popular topic is degradation of the Baseband binder as explained above.

So I understand that it is not possible to take a baseband from another disk and insert it into the repaired disk, the baseband is not programmed, but rather nand?

Anyway, I will finish reading the soldering thread this weekend, which gave nutergsm, I will buy the necessary parts and try.
I have nothing to lose, and I intend to act in this direction in the near future.
There are already 2 PS3 with YLOD waiting in line, so maybe at least the consoles will be able to get back on their feet: d

Eeprom is programmed, not nand. Nand after SN is nothing to Baseband, but SN from Nand must match SN in eepromie, that everything worked There is also a corrective eeprom but its content is not important (you can reschedule the system from another board)

-1 is not always a baseband, in many cases the problem was caused by the U2_RF system, e.g. on the PP_LD09_PLL_1V05 line when it comes to 5s.
However, to the author of the post, I suggest that you give someone with experience to do the repair, since you have never done it.
This is not an easy task, especially in 5s flooded with resin, you tear the pads and the plate will be suitable for a dose. You should start on low-value discs if you want to learn this ...
But if you're about to go about it, it's best to start with a gentle reflow on BB to verify. If it works and you catch the net, you found the culprits. Just remember that the same warming up will not be enough, the problem will return again, a matter of a few hours, or even a few days. It is necessary to perform reballing if the repair effect is to be long-lasting.
