Paranoid about no IMEI (want to flash) - Galaxy S III General (US Carriers)

Hey guys Im just asking for some input on guys who have flashed before, what are the chances of having your imei wiped while you root and flash the aokp rom. i realllly want to flash so badly but im so scared of getting the bug, and if i got it id be screwed, cant return the phone as i bought it out.
so help me out guys, are the chances of getting that imei wipe bug high or pretty low? is there anything that can be done to avoid it? ie the safest rooting method or something?
thanks so much :good:

[Q] How to Root?

So I've been looking all through the Samsung Galaxy S I9000 threads and can't find ANYTHING on rooting this phone. I've rooted several other phone models, including the S2 and I've never had so much trouble finding info on rooting a phone.
Could someone place a sticky on this?
I'm trying to root this Bell Canada Galaxy S I9000 on ver 2.33 and I can find plenty of instructions AFTER rooting but that doesn't help me if the phone can't even access the system
I just want to root this and install Cynaogen 7 on it. Help, please!

Very useful thread, thanks a lot ^^.

OK here is a good starter guide.
The most important thing is getting a rooted kernel that matches your current Android version, wrong version will lead to bootloops and sadness. Once you've got a rooted kernel and CWM recovery you can backup and flash CM7 (twice, trust me).
CR Root thread has a long archive of kernels, should have one that matches your version
There are several methods existing in order to root your phone.
If you just need to root without changing your ROM, flash a kernel via Odin (kernel examples : Semaphore, CF-root, ...)
Why I'm rooting
Thanks everyone for your help.
TBH I'm rooting this for my brother's friend. He unplugged the phone in the middle of an update and now it won't make or recieve calls anymore... Soooo I'm guessing if I install a new ROM on it, it'll fix the whole issue... I could be wrong though, but it's worth a shot.

He unplugged it during a Kies update? Check if the IMEI matches the sticker on the phone. If the IMEI is corrupted you might be best to send it back, a custom ROM will void any warranty.
If the IMEI is OK then rooting it and flashing a stock ROM might clean it up.
Best of luck

This is all hearsay from my brother, all he told me was this guy unplugged his phone in the middle of an update. If it was OTA, or Kies, I don't know. I'll check the IMEI, but I know his warranty is up crap creek, he tried to get it fixed under warranty and they wanted to charge him over 600 bucks.
I'm going to assume the IMEI is fine though, as he's getting data just fine without wifi being turned on, and he's connecting to Bell Canada, he's just not getting voice calls in or out.

Flash a stock rom using g heimdall or Odin and go from there. Putting cm7 over it without calls working might make the issue worse. Flash stock first. Then install clockwork mod kernel, ie hardcores speedmod. Then flash cm7.no need to mess around rooting. U just need cwm.

Slow Internet (3G/LTE) after 4.4.2 Update

Hello Guys
Well, let me get straight to the point. After my old rom (Revolution HD3) was draining my battery pretty fast, i decided to update to 4.4.2. Well, i downloaded the latest 4.4.2 for switzerland from sammobile.com. I flashed it and it somehow was all laggy and i had fc's the whole time. After some time i was able to use the phone anyway, but it was laggy. And the problem was that my 3G connection was EXTREMELY slow. I got connection time outs the whole time and wasnt able to download anything. Well, i thought it was the rom i flashed trough odin, so i downgraded to 4.2.2, my original rom, and updated trough KIES. The rom wasnt laggy anymore, but the 3g/4g was slow. I tried different Modems and Kernels. Nothing Helped. I then decided im going back to a custom rom but the flash failed. Then i tried another rom and it failed again. So i thought it may was cause i was on 4.4.2 and tried to flash a custom rom that was 4.2.2. I then tried to reflash my stock rom trough odin, and it FAILED. And that's how i bricked my phone. I can still enter Download Mode, but can't enter the recovery anymore. What do i do? I'd like to solve both problems.
Thanks guys
Btw: I've got an I9505
I assume you didn't wipe anything before you flashed stuff? Thats like rule number 1 to do.
You can try flashing a recovery true Odin.
Hej Guys
Um.. Just to let you guys know, it is possible to downgrad to 4.2.2 from 4.4.2. I just did it this morning and had sucess. But the problem with the really slow internet connction still is here, when im on a 4.4.2. And, it is the same with custom roms running 4.4.2. I tried different kernels and modems, nothing helped so far. As soon as i was back to 4.2.2 it had the usual connection speed. I called my provider and also called samsung itself. Obviously, they both told me to bring the phone back for garantuee. But well, as i know it's a software problem and not hardware, i wont do that. So can you guys help me? What should i do next? Actually im back on 4.2.2. Thanks
Edit: Oh, and ofc, i did everything like wiping/factory resetting, wipping preoload etc. It's not my first time flashing.
It's not possible to downgrade from 4.4.2 to 4.2.2! End of..

Are you serious dude? Im running 4.2.2 right now. What is your point?`I didnt even ask about it. I asked about a solution to the problem that i get slow 3G/4G on my I9505 when running 4.4.2. If you want a proof Pic about it running 4.2.2, i can give you one. But i dont really get what your point is.
Hang on hang on hang on, it is common knowledge that you cannot downgrade from official samsung 4.4.2 to official samsung 4.2.2 because in odin you will get failure at aboot.bin because you cannot downgrade bootloader.
How ever what would be really good is instead of just trying to say it then jumping out saying what's your point, we'll my friend the point is, it would be advantageous to everyone in the entire samsung galaxy s4 i9505 community if you can tell everyone how you did it.
My perspective is your doing a bit of flaming.
Pictures really won't prove a whole lot as anyone can do some build.prop edits and show different rom name and version.

Well, if it sounded like flame to you, it wasnt. I didnt create this thread to flame others. But i wasnt kidding saying that i downgraded to 4.2.2. Here how i did it:
Was running 4.4.2 (I9505XXUFNB9)
Flashed TWRP recovery.
Flashed custom Rom 4.2.2, which FAILED!
Flashed Official 4.2.2 trough odin, which FAILED!
Flashed TWRP recovery again, since it was somehow damaged from the flash before
Flashed Wanamlite 4.4.2
Flashed Custom Rom 4.2.2
Flashed Official 4.2.2 with succes.
Im not sure what part of those flashes were essential, but i have no reason for liying to you. What would be the perks if i did?
But now again BTT, Did anyone else have that problem of slow interenet connection? Or is it just me? Maybe some ideas?
Regarding slow Internet maybe it's your carrier with issues.
Maybe the downgrade back to 4.2.2 has created issues in its self. Have you checked your baseband matches bootloader and build?
A problem we have is we can't see the version of the 4G modem (non-hols) so that might be also an issue.
When you flashed back did you do a factory reset?
In regards to downgrade do you still have the Knox bootloader?

Well, i called my operator and the girl on the phone said that some people already called with the same issue, but its not on their side. It's a problem with the update samsung released. After the downgrade i had my Knox Bootloader and everything worked like it always did.
Yesterday Sammobile released a new ''rom'' for my country. Downloaded it, flashed it and it works great now. I have a bit of a fast battery Drain, but the problem with the slow internet seems to be fixed.
Again: 4.2.2 worked perfectly after downgrade. It had no issue, No FC nothing at all. Maybe i was lucky? No idea, but im happy my 4.4.2 works now
Thanks anyway for your help guys
Edit: Yeah, my bootloader matched both baseband and build.

If you had done your homework, you would know that in almost all cases Samsung repairs it even with Knox set to 0x1. They even publicly stated it in the Netherlands that they will repair your phone even with custom roms.
And you don't know the law in Switserland. Nor do I. So you can't say that in Switserland his rights are voided by flashing.
If Samsung doesn't give you the warranty, then you still have your consumer rights in the European Union (not that Switerland is in it). No flashing, modding or other chances decleine you your rights if it's not related to a hardware failure. In the countries that you and I live in, it will never void your rights if the damage is not related to flashing or modding.
So well, i think that in switzerland they actually WONT repair it if you flash it, but i aint sure about that, since i never had to send it to repair. But anyway, it was only a software problem on their side. They released another version for switzerland and it seemed to have fixed the problem. I have a bit more of a battery drain, but i actually think im just too used to some other custom roms. Anyways, thanks for the help guys

[Q] lollipop official stock problems

Hi im a bit of a noob when it comes too this flashing business but i managed to update my i9505 to lollipop using odin and the official stock rom but the problem i have now is my network signal is now terrible where it was good before is ther anyway that a noob like me can fix this issue? Im in uk on giffgaff (o2)
i have never rooted my s4 before and if some one has a noob guide for rooting from lollipop so i can custom rom it up i might give that a look too, I wouldnt mind a nice slim custom rom with a few extra tweeks and without all the google and samsung rubbish that comes standard..
Thanks
P.s sorry for all the questions and sorry if this is in the wrong section
The signal problem is probably caused by the modem.
You have to flash the latest modem for your phone, country and carrier.
If you already are on the latest modem then a lollipop modem might help.
Here you can find a guide on how to root lollipop.
If you want a slim rom you better try CM12 or GPE. If you like touchwiz then look for a touchwiz based lollipop rom around the forum.

Is your phone branded or unlocked? Coz this is very important. UK(O2) still without lollipop update. This is the possible reason that you are receiving weak network signal.

Need Help Fresh Install of Stock 6.0

I did a mistake, it is possible to move this thread on help section?
Hi all, today ASUS released the OTA but in some days the full rom will be also avaible.
I want to do a fresh install but i don't know how do this :crying:
I was a Samsung S2 Plus user and there was really easy flash something but on ZF2 with fastboot and recovery i don't know where go.
I am using full stock ROM unroot never touched. There is a SAFE way to flash a full firmware? I read that someone deleted some partition and IMEI was lost
Thanks for the help.
Regards,
LightDestory.

have frp success. can i root?

as the title says i was abke to successfully frp bypass this verizon s7 that was giving to me by a friend. i included ba screenshot of its current info to help find my answer. it is on 7.0 and everything else is listed in the pic. i just dont wanna get relocked or even have to do it again cause i feel strongly that i lucked out on that try tbh. and i dont know if i should upgrade and root, stay where im at i think ull understand what im asking. thanks to anyone that has any input.
EDIT///throwing the edit just in case this post somehow helps someone in the future the answer to the question asked above is yes you can. A lot of weird shifts going to happen different than the directions given in the Rom dev thread and your face lots of froot loops and we are shutdowns but eventually you'll have root and or the custom rom from the rom thread.
