Homebrew a9lh question

Hello its me again i am running sysnand and rxtools on a 9.2.0.20U, i am currently having trouble with httpwn, i keep hearing good things about A9LH, what exactly does A9LH do?

A9LH is the most reliable boot method (100 %)
It can launch any CFW that has A9LH support
Once you have it installed, you can unbrick your sysNAND without a hardmod
Can launch Arm9 apps (Decrypt9, EmuNAND9, GodMode9)
Again, more reliable than menuhax

Anything I missed @Margen67

can it bypass sysupdate?

can it bypass sysupdate?

It can be fully updated and STILL be better than emuNAND. It has almost no limitations

--------------------- MERGED ---------------------------

Like, 11.0.0-33U updated

 

[Mrzeldaootfan]

i already have rxtools and sysnand installed, will i be able to connect to the internet like on alpha saphire? if i install a9lh, also i would like a guide

I would recommend not trying it unless you have a o3ds which can directly be downgraded system version 2.1, if its N3ds I am sure its even more susceptible to bricks than my o3ds which got bricked because I tried that otp helper step in the guide, basically you have to merge emuNAND with sysNAND to access system version 2.1 "safely", you save like 2 hours not trying that, if you have a o3ds just by making a sysNAND backup then directly downgrading to get the otp works 100%, anyways if its a N3ds you have to follow the guide as closely as possible and make sure that you haven't tampered with emuNAND or RedNAND which I guess you already have which can with a high chance lead to a brick unless you're coming off of a vanilla N3ds to get A9lh to work, which means starting from scratch and getting to CFW which is what the guide is aimed at, and not at existing users of CFW on menuhax+EmuNand setup which I assume you are using.

im just looking for something so i can connect to the internet on alpha saphire, i tried ctr but it will not work for some reason

i might have a solution to my problem also, will i be able to install cia files on 9.6?

also i have o3ds

If its a o3ds and if you know what you are doing you can get your otp in like 10 mins, you just need a sysNAND backup to get back to what firmware your system was before you downgrade it to 2.1, the only reason for this is if you have in anyway or form tampered with your emuNAND it can lead to errors while merging it with your Sysnand which bricks any 3ds 99% of the time, I am just wondering why people haven't made a guide to downgrade straight to 2.1 on a o3ds without all the hassle of formatting then setting and then formatting a emuNAND, this gave me a idea of writing a guide of my own for o3ds specific people.

W/ a9lh, you can install CIA files on any firmware

thanks now, do i need to update my rxtools and emunand while updating? im also confused on how to install a9lh

https://github.com/Plailect/Guide/wiki/Part-4-(Getting-the-OTP)
Start there follow the tutorial directly

 

[Mrzeldaootfan]

ok, also, i use the Health and safety method to install cia and fbi once in a while if that changes anything

 

[Deleted User]

Nope
Just follow everything (maybe start at the beginning if you are worried. I would)

... i am running sysnand and rxtools on a 9.2.0.20U, ... what exactly does A9LH do?

Prepare to go deep into the rabbit hole... as for those seeking knowledge of A9LH, there is no greater set of posts than the following:

Spoiler: A9LH MegaThread

Table of Contents:

Introduction, BootRom, ARM9Loader Theory
ARM9Loader v1
ARM9Loader v2 (1/3 and 2/3)
ARM9Loader v2 (3/3), Conclusions
OTP dumping progress post / summary
Plailect's OTP Dumping Guide (external link)
Arm9LoaderHax source code (GitHub link)
Summary of differences from prior *hax (1/3)
Summary of differences from prior *hax (2/3)
Summary of differences from prior *hax (3/3)

If you just want a short answer:

A9LH uses a combination of system flaws to obtain control of the 3DS far earlier during boot than any previous *hax. In fact, control is obtained before the firmware is loaded. The boot rate is 100%. Getting there requires temporary downgrade to pre-v3 firmware (e.g., v2.1).

See full details in the mega thread.

Youtube guides are outdated. You should read Plailect's guide instead.

Only need to install GBA/DS CIAs once
Save space on the SD card
Faster to boot than menuhax

You got most of them, though.

 

[Swiftloke]

More control of the system than your typical arm9 exploit, as it runs before the OS does

arm9 gives your 3ds cocaine and makes it load at warp drive velocity.
You can also do anything you want and even brick it (if you even have enough power in your mind to intentionaly brick somehow since it is impossible.) but then you can unbrick it with the power of backups.

This doesn't have a lot to do with a9lh, only with a no-emuNAND/redNAND configuration. I obviously agree that a sysNAND-only configuration is tons less annoying with a9lh (no need to manually boot something through unreliable means everytime the 3DS is turned on) but still, those two arguments are not really a9lh exclusives. And they are not even guaranteed with a9lh either since the user can still use an emuNAND or a redNAND.
Now yeah, you can say "emuNAND/redNAND is bullshit, sysNAND masterrace", yeah if you want, but this doesn't mean sysNAND-only is a forced feature of a9lh.

Your statement seems a bit contradicting. Before A9LH, emunand/rednand was the only way to hack past 9.2... allowing for CIA installation and the like. Its not like theres A9LH, emunand peasants, and then some third option using neither. A9LH is the only hack method that provides the advantages listed. And while its not a forced feature.. it IS still a feature that is A9LH exclusive.. which basically makes your point invalid.
