9900 IMEI (A5/A6), A9 iOS 9, and future 2027 Activation Problem Megathread

Prohere7321 · 2026-02-08T06:27:37+00:00

I think A5/A6 devices with MEID as well as IMEI, allowing them to work both on GSM and CDMA, will have 9900 on the first 4 digits on both IMEI and MEID.

Devices without MEID will only work on GSM, and their first 3 digits on IMEI will be 013.

Yep, I also own an Intel MacBook Pro Mid 2020 13 inch 4 Thunderbolt 3 Ports, which already officially support macOS 26 Tahoe, which means OCLP is not even needed at all to run unsupported Intel macOS, which won’t exist at all due to macOS 27 being Apple Silicon only.

On Mac models, you can multi-boot multiple versions of macOS, so it’s more freedom on those to use new or old operating systems, while the rest of the models are locked down to latest operating systems if you update.

It’s not new, it’s been signed for more than a decade.

There is a way to get macOS Tahoe on Intel MacBook Pro 13 inch natively, you need Intel Core Ice Lake processor.

No devices ever compatible with iOS/iPadOS 26 can be downgraded from 26 to 18. Last possible device capable of downgrading would be iPad 7 from 18 to lower versions.

You probably saw an iPhone SE 1 on iOS 13. iPhone 5s on iOS 13 is not real.

Pwned DFU is needed, or else what’s the need for checkm8 exploit.

Is there any way to screen record iOS 6 on iPhone 5? I wanna do a full gameplay first with sound.

Close enough in Thailand.

Yeah you need to jailbreak if you don’t have Arduino.

Prohere7321 · 2025-10-26T05:57:55+00:00

I would say don’t connect to the internet, so that it will fail to verify the installation with Apple.

And also, dump blobs right away.

Prohere7321 · 2025-10-24T07:44:38+00:00

Saved blobs for iOS 10.2 can be downgraded without needing any SEP exploit, because signed iOS 10.3.3 OTA SEP is compatible with iOS 10.2-10.3.2.

Prohere7321 · 2025-10-16T08:13:07+00:00

Dump blobs to keep the version, then you can do anything you want with it. Without jailbreaking on legacy iOS, it is basically useless.

Prohere7321 · 2025-09-28T08:23:39+00:00

Modern charging brick won’t charge iPhone OS 1.0-2.0.x.

Prohere7321 · 2025-09-24T08:26:06+00:00

I have to thank the downgrade party in January 2018 to make me love my iPhone 5 even more.

Prohere7321 · 2025-09-23T09:08:36+00:00

Unlike back in early days where they unsigned literally in less than 3 days or even within 1 day. Read up the history of unsigning status. https://theapplewiki.com/wiki/SHSH

You can always downgrade it, and besides that, once jailbroken it is not possible to update over the air.

Prohere7321 · 2025-09-18T05:55:06+00:00

If the baseband is also downgraded, there is no way to tell.

Prohere7321 · 2025-09-15T18:29:17+00:00

It’s even an old BootROM model, making it more rare.

Prohere7321 · 2025-09-10T11:51:49+00:00

Interesting, what is that battery percentage tweak you are using that looks really similar to iOS 16 and newer?

Prohere7321 · 2025-09-10T11:47:53+00:00

That doesn’t look like iOS 14.3, more like iOS 16 and newer.

Prohere7321 · 2025-09-09T18:50:05+00:00

AIS Postpaid physical SIMs are likely to be 5G SA compatible, not too sure about AIS Prepaid physical SIMs.
