looks like ppl who r using wifi only model failed to flash a kernel. does this mean wifi model cant have custom roms available ? ohno!
It's not failing to flash a kernal - please read. It's failing to boot after you flash an incorrect boot image.
sry . n thx for ur correction. but what i really care is, is this mean wifi model xoom wont have custom kernels? or just need to find out wat is the difference between the .img of 2 version

Relax dude. I wouldn't say the wifi model xoom won't have custom kernels ever. Its just in order to create custom kernels for the wifi model xoom, the user has to be able to root it first to modify any changes if needed.
The problem right now is that when you flash the hacked boot.img (wifi+3g) to root your wifi xoom, people are having trouble rebooting the xoom which is soft bricking their xooms.
My kernel "should" work fine with wifi only Xoom. Be sure to back up your boot.img first.
The WiFi only has to get past rooting before worrying about kernels and ROMs that aren't even out yet.

Hi,
I`m curious how/if undervolting (and overclocking as well) works on Nexus S after the ICS update. First, I must point out that I have a NS with stock rom, never been rooted, bootloader locked with official (now not working) recovery. The reason for this question is that the only reason I see for rooting this device is to undervolt to get more battery life. Btw I`m satisfied with the battery life I can get but why not to try to get some more ...
So, if I would root my device, what do I have to do next? Do I need another kernel? If yes, which are compatible with stock ICS? I want to stay on stock cause thats the reason I went for Google phone, the official updates without the need to flash roms ...
if the only reason to root just to undervolt...maybe there is an app in market can help u..
but if u use custom kernel...u can have more room to tweak it to ur best preference.
u can get custom kernel here: http://forum.xda-developers.com/showthread.php?t=1336529&page=91
but still in testing phase
for rooting...here: http://forum.xda-developers.com/showthread.php?t=1396959
Hi
Thanks for your reply, but I`m afraid root is always required for undervolting ... But thanks for the kernel link!
Hi all,
I've a big problem ! I've rooted my Galaxy tab 2 until there no problem everything works fine. After that I've installed like explain Rom Manager and Clockwork 3 droid.
I made a backup first on my external card and then I try to install the custom rom Cleanrom. And since then I'm stuck on the Samsung Logo! Impossible to go on recovery or do anything. !!
Please Help what Can I do?
Ok some news , I succeded to acces to Odin mode and I don't know why
Finally I've try to root again the samsung to be able to access to recovery. I let you know
Perfect I finally succeded to install the custom rom! I don't know how but It's work
I'm trying now to overclock but SetCpu won't detect a bigger frequency
Any idea?

You need to have a kernel that supports overclocking, you can find some kernels that supports that in the galaxy tab 2 dev section
Sent from my ST18i using xda premium
Ok but there is only 2 kernel availaible Infected Rom or CleanRom and I don't see any info if one of theses have overclocking possibilities :s
There is no overclocking available for the Tab 2 yet. One of the developers will have to modify a kernel first. Secondly, ROM manager is mostly for phones only, it is not compatible with this tablet so don't use it. You seem to be one of those that just fire ahead before looking first so make sure you read the OP in the ROM your installing first so you don't mess up again. 3G models and Wifi only model roms are not interchangeable.
Thanks for your answer !
I've installed CleanRom 1.1 on my 5110 and it seems to work fine
So I'll wait now. This custom Rom works better than the default one

Wrong, There is no overclock kernel for the 10.1. Theres plenty for the 7.0

Wrong, They will work but the user will lose that 3g functionality.
We have 2 valid stock ROMs for 7" one for P3113 model ( without GPS module ) & the other from SAMMOBILE for P3100 ( Turkey ).
P3100 factory ROM works on all P3100 phones in APJ region...this may not work in US or Europe models.
But if you bricked your P31XX, these ROM's will help you to get back on track provided you are able to boot to download mode correctly.
I lost my wifi when i was already running a google kitkat rom and tried to update to a newer version of the same rom.
and after endless flashing different roms and wifi fixes i gave up and took it to a phone repair shop..
He tried to do the same thing i was doing and then couldn't get it to work either.
And told me i need to replace the main board $220 later i am now here.

the phone doesn't seem to have root and has stock recovery.
putting it into download mode i get official now. before i had knox01
I have read a few post about a few people that have lost there wifi but nobody has been able to explain why this is.
I really would like to put a kitkat rom back on my phone, but my ill never hear the end of it from my wife if i brake my wifi again.
is there a method i should follow to minimize the risk of this happening again.

I would say, its ur old baseband.its a 4.2.2 now.
Do you know which one do u had before?
Flash a 4.3 modem with Odin and then i think it will be working
I use a MJ8 baseband on my 9505 and tried alot Kitkat Google Editions ROMs with working Wifi

Why would he flash a 4.3 modem when he has a 4.2.2 firmware mate? Your post doesnt make any sense. Please explain? The op is asking for an opinion without him getting a wifi problem later incase he flash any custom rom/kitkat in a future. And gutterat if you are going to flash any rom do a nandroid backup before you flash anything. IE: EFS and such.

Sorry i edit my post.
When he had a 4.2.2 baseband before too, and tried to flash a Kitkat Google Edition, Wifi won't work with 4.2.2 baseband. U have to upgrade to a higher baseband than 4.2.2 for a working Wifi.
MJ... or newer

im not a total noob
i have rooted and put custom roms on many of my other devices
Galaxy 1
Galaxy 2
Galaxy 3
Acer A500
Note 10.1
Ouya
this is the first time i have broken something and not been able to fix.
I am unsure if the wifi just crapped out or it was a result of me flashing it.
last time when i lost my wifi i think i had nandroid back up ( made a back up in philz recovery )
when i restored still had no wifi
is this how i achieve a nandroid back up or should i be doing something else ?
was it a knox issue that broke my wifi last time ?
should i look into rooting without changing knox
warranty isn't as issue as i don't have any..
Did you buy a new mb
Didnt you try warranty
Was the repair guy a noob
100's of threads about broken wifi, didnt you try any of them fixes.

thanks i think ??????
tried heaps of different WiFi fixes and Roms and kernels spent 3 weeks flashing different things.
the phone repairs apparently tried all the same things and had no luck.
I've been working on a custom ROM for the Verizon Galaxy Tab 4 (SM-T537V and the SM-T337V) but haven't had much luck flashing them to my devices.
I've been trying to flash the 8" version using ODIN after making customizations to the ROM (removing apps, etc.). This worked fine on my Verizon Galaxy Tab 2 7", but it doesn't seem to be working well on the Tab 4.
My process: unpack the system.img.ext4 and mounting it, then modifying and repacking, using simg2img and make_ext4fs, respectively. Both of these are made as 2400M size partition.
I've tried ODIN 3.0.9 and 3.0.4 and flashing the system.img.ext4 alone vs batched with the rest of the stock ROM files, but always get the error: "secure check fail: system" when the system.img.ext4 starts to flash.
Yes, these are .tar.md5.
Any ideas how I can get this to work?
Bump bump. Anyone have an idea about how to do this?
More generic question -
Does anyone know why it would be difficult to flash a custom ROM from Odin? What is locked down by Samsung to prevent this?
I was able to do this easily with the Galaxy Tab 2, so I'm trying to isolate what may have changed.

Most custom roms now a days are usually zip flashed roms. Probably has to do something with Samsung not flashing unsigned firmwares in which you can do so. I never use odin but only for cfautoroot. Thats my guess. Maybe it has to do with how the rom is built in order to flash it.

Thanks for the tips! That's basically the answer I've settled on as well, after lots of testing. I'm not sure why the Tab 2 would allow unsigned ROMs to flash, while the Tab 4 seems to dislike me repackaging the /system partition and flashing it.
I'm assuming there is no way to re-sign a ROM in the same way as the stock signed firmware, so I guess I'll have to explore flashing with a zip. In order to do this, I would need either Clockworkmod or TWRP on the device, right? I don't think it is available for the Galaxy Tab 4 yet. Is it possible to flash a custom recovery on the tab 4 that is meant for another system, or does that basically always brick it?

What size is the tab 4 your talking about? Sorry I only own the tab s 10.5 and both of our devices got ported to twrp. Not sure why there isnt a custom recovery for some tab 4 devices but there are developers in the tab s thread that ported cwm to the tab s. Maybe someone can build on for the tab 4? And what version of twrp are you talking about/ tab 4 varint? It probaly would boot into recovery is what I think. Sorry as I do not own the device or know any of the model numbers :/

It's the Verizon Tab 4 10.1" (SM-T537V) I've been thinking about porting CWM for my Tab 4 but I don't know if it's possible or if I'm up for the challenge technically. Maybe the S is similar enough to flash onto the Tab 4.
Would all the Tab 4 variants have the same recovery? Or would they likely be different?

I believe the recoverys should be the same as they are the same size and almost identical devices. If the recovery was built on the wifi tab 4 10.1 it most likely will work. Idk if it will though. People that on the tab s forums that recoverys for our wifi tab s work on the lte also. Idk. I think as long as they have the same chipset (exynos etc) and size it should he good. I cannot confirm this though and ill have a look at the tab s forums to see if it really does. Idk if it will.

Ok, good to know. I couldn't find any places where people were referencing using the wifi Tab S recoveries on the LTE / Verizon versions, but I'm probably just missing it. Any idea why the Tab S bootloader is unlocked / able to have a custom recovery installed? It seems like a lot of newer samsung devices don't have this ability. Was it through some workaround like a Loki equivalent? Thanks again for all the great info!

Only wifi and lte models such as sprint perhaps verizon and unlocked lte devices have unlocked bootloaders. I think we had custom recoveries because either from the firmware release or someone got their recovery. Img pulled for beanstown to port. We had root on both 8.4 and 10.5 inch the following week after launched and custom recoveries by ds troy (recovery builder for twrp) few weeks later. I dont know whats up with your guyes tab 4s not getting recoveries. Are your tab 4 chips exynos? Because the tab s have exynos chips. We have developers working on kernels and roms even though they dont own the tablet. Must be how much sources are availbe? Idk if verizon bootloaders are unlocked but sprint and wifi ones are.

So if I end up not being able to flash a custom ROM on this, is it possible I can just build a script to change everything on my ROM's system files using my root permissions? Not sure where to get started with this, since I've been so focused on the ROM until now. Maybe some sort of batch file run through adb?

you can do it via ADB, just make sure to issue the "stop" command first. you can batch all this with the help of "su -c" which runs a su command without interactive shell

Yeah, thanks! That's what I've been working on recently. Mostly just stripping out bloatware and changing a few things. I'll post the full command here once I'm further along.
I'd like to be able to change the SystemUI.apk but haven't been able to successfully deodex it yet (the deodexed version loses the notification panel!)
make sure you use apktool 1.5.2 and see what the results are
then try apktool 2.0.0 RC3 if no luck

Also, try deodexing with QuickDeodex, it tends to create good results for me. experiment with different Smali, baksmali in the tool's resources folder. sometimes you need smali/baksmali 2.0.3 and sometimes you don't. it's a crapshoot.

This worked really well, thank you for the tip!
Did you ever solve the custom ROM challenge - or did someone else solve it elsewhere, please?
I can get one for $95. used but I only want it if it can be changed to a custom ROM with Google, MS, etc. bloat, spyware, etc. purged.
Thanks!
How can I get the file download
On Custom Oreo ROMs/kernels such Renovate ICE O, Batman ROM, Nox Kernel, notorious kernel , Wifi does not work on my S8 G950F. The only way to make these work up to now, was to restore the boot image from stock rom.
Whilst restoring stock boot.img does resolve the issue, it creates another in that after reboot wifi takes about 2 mins to turn on.
This Solution Worked for me, but doesn't always work for everyone, try it:

the stock boot is one you would take from twrp, or if you don't have that can install soldier rom, skip all the install options, then just backup boot in twrp
I have very kindly been given a temp fix by @Noxxxious who makes the truly excellent Nox kernel. Will update as this develops & hopefully share a perm fix for everyone

I take it the 2 files trick didn't work for you? So are you facing the issue of really slow WiFi start-up after reboot? Glad your here anyway. The more people we get the more chance a dev or devs will take notice
Still dealing with this in 2020. I'm using a Japanese S8+ with stock Oreo firmware and a custom kernel, the second I flash Magisk and my boot image gets replaced, WiFi breaks. I checked the file directory mentioned in post 174 and I see both files are present on my phone, unless the files @noxxious posted are modified in some way.
