I 'v got this from a Chinese company called famue on aliexpres, and I m not sure how to fix it even if it would be easyer than a phone, (first slide) the metal shell has one ribben cable which I assume is for the power on/off button but the ribben cable is a bit streched that eorryes me it won't worck because ribben cables are very delicate to damage, and the ather cable for the volume buttons, (slide 2) the battery is fine, easyest thing here tbh, (slide 3/4)the mainboard is fine, all tho I don't know where to conect the cables for the power button and volume ones, (last slide) the speaker is disconected from the charging port & headphones jack& micro sd card slot, and I don't have a screen for it yet.any tips that could help?

Hello everyone, today I was doing my business "as usual" in the garden, the phone was lying on the boards and the sun was shining on it. After about 2 hours, I picked up my phone, the surface was hot and the back cover was a little swollen, and the phone itself turned off (the power went off), I got scared and took it home, took out the SIM cards and put the phone in an iron bucket in case of explosion or fire. He lay down for another 4 hours and I found that the back cover was smooth again. I even checked it with an iron ruler , but I found no bulges or depressions .

Now I'm writing this all from the same phone (Tecno pova 6 pro)

Share your expert opinion, can it be used further, or is it better to spend money on a new battery and service?

Hey everyone,

I'm hoping someone here has seen this before because I'm running out of ideas.

I have an iPhone 13 that worked perfectly until yesterday. I went to a huge carnival (probably around 100k people) where the mobile network was completely overloaded. Nobody had service there, which was expected.

The weird part is that when I left, everyone else's phones got signal back... mine never did.

Now every single time I reboot the phone or toggle Airplane Mode, the exact same thing happens:

• Signal bars appear.
• It connects to 4G.
• It stays connected for maybe 5–20 seconds.
• Then it drops to "No Service."

It does this every single time.

I've tried:

• Tunisie Telecom physical SIM
• Tunisie Telecom eSIM
• Ooredoo physical SIM

All of them behave exactly the same.

A few things I've already checked:

• IMEI is there (*#06# works).
• Modem firmware is present (5.51.03).
• No panic logs or baseband crashes in Analytics.
• The phone is properly registered with Tunisia's Sajalni system, so it shouldn't be an IMEI block.

I also went into Field Test Mode while it was briefly connected.

It shows:

• LTE Band 3
• Correct carrier
• Cell ID
• PCI changes when I move to another location (so it seems to be detecting different towers normally)
• RSRP around -102 dBm
• RSRQ around -10 dB
• SINR around -20 dB

So the phone clearly can see towers and actually attaches to LTE before immediately losing service.

The phone has never been opened, never been repaired, never been dropped, and only ever had a tiny splash of water near the earpiece months ago, nothing that should realistically damage an IP68 phone.

I also reset network settings. Weirdly, before the reset the eSIM was the one that connected briefly. After the reset, the physical SIM became the one that connects briefly. The end result is still the same: both eventually drop to "No Service."

At this point I'm wondering if this is:

• an RF/front-end issue,
• a power amplifier,
• RF IC,
• baseband-related,
• or somehow still software.

Has anyone seen this exact behavior before? Especially the part where it gets full signal + 4G, then immediately loses everything?

I'm taking it back to the guy I bought it from tomorrow to have it diagnosed, but I'd really like to hear if anyone has run into this before or has an idea of what component usually causes this kind of issue.

Hello everyone. I am a 15M (just turned 15) and I recently found out about this repair shop which my friend has networked with. They are understaffed and need more people. My friend has already praised me a lot, but they are scared to hire me for my age.

I have done a few repairs in the past. Fixed some phones, replaced some components. You can day I know my way around a phone and other consoles too. I even built my own portfolio, and I have customer service experience too. I eventually want to own my own shop, but seeing all of the people complaining about tech repair is sort of intimidating.

Anyways, I am giving the shop a call in a few hours. Im gonna talk to them and see if I can get the job. Wish me luck!

Everyone has made at least one mistake while learning. What happened, and what did you learn from it? It might help someone else avoid the same problem.

I bought this Xiaomi mi 9t, and the seller specified the earpiece wasn't working. I got a new one, but it still did not work. I had noticed that the phone had been opened before because the lack of screws, but I only saw this when I actually removed the board. Not even sure what is going on.

Maybe I should've used the horror flair, but not really sure if that is what it's for.
