I'm another owner of the K1. I've had it for a while now since xmas and I do like it, but I cant get over the locked bootloader. I was hoping to be able to overclock it so apps for school would run nice and smooth but it doesnt seem to be happening.
Do you guys think I should hold onto it and wait for a root with recovery and hopefully some mods? Or just sell it and try to get a tegra 3?
I'm torn between this man because I have a beefy laptop so I dont need a quad core tablet, I just want it to be smooth. Kernels, overclocking and custom roms always did it for me in prior phones, now its like we're forced to upgrade every year
shoot me some advice

It has already been rooted. Once rooted you can OC all you want.
Thanks for the reply. Just wanted to make sure because the K1 doesnt even have its own category in xda.
So, this wont need a kernel to oc?

I do not OC, but have read links saying there are OC tools and all you need is root. So, you'll have to Google it knowing that you can get root and see if that's correct.

timmyDean,
Thanks. Im just hoping to not run into any problems with overclocking it. Ive rooted a lot of phones and overclocked them all.. even overclocked my pc. Since I started I cant stop lol. Its compulsive, i know, but there is a difference in responsiveness so it's not all my my head lol
I'm on A301_13_13_111209_US
Kernel 2.6.36.3
Do you know which method I should run?
Sort of confused in your development thread about using different blobs and updating with OTA.
Yup, http://forum.xda-developers.com/showpost.php?p=21309379&postcount=50
This will flash you directly to 13_13US rooted!
You're the man! I'll be attempting this tonight. Hopefully all goes well.
One question tho, if someone manages to port over cwm, will there be custom roms and so on for this tablet? I saw someone working on porting cwm, but doesnt look too promising.

CWM is already ported. I haven't tried it, but according to the developer it works. I have no reason to use it because there's nothing I want to load. I suspect it's just being used to make backups because I haven't seen any chatter on custom ROMS. As far as custom ROM development, who knows. In my opinion these Lenovo are 'junk'. Again, my opinion. Lenovo doesn't want you to modify their devices, so they make it hard to root. They want you to go to them for a custom ROM. We've tried that and it's a joke. We develop drivers and special drivers for hardware and develop several applications for vertical markets. Chances are, if you have a HC tablet you've got a driver buried in there that we wrote (our NDA keeps me from saying who, but I would say every make listed in these forums --if I were to guess). Our vertical applications cannot be sold as a solution to a fortune 500 company with us demanding they buy a custom Lenovo hardware. That has only worked with Government sales because the Lenovo suits convinced them that they are super secure.
Anyway, good luck

Thats some good info man. Now I'm thinking of rooting and throwing it up for sale as rooted and buying a transformer prime

Also, might I add they seem to want to restrict you and feed you a bunch of their 'bloatware'. A few months back, when they were in talking with our management team they said they were offering a complete solution hardware and software. They want to make money on their Marketplace applications, etc etc. I sort of got the impression they thought that was where the real money was and not in just selling tablets.

Now that makes sense. Theyll never release an unlocked boot
This sucks man..
Going to root after ghost adventures
One question before I go all the way with it, whats the procedure for updating with new releases? Best to wait for your releases?

New releases, go for it:
This is what I do:
1. Backup my apps because if the OTA knocks out root(#), you have to flash it.
2. I install the backdoor
3. I backup the su
4. I lock the su and backup su so updates HOPEFULLY don't break root(#)
5. Then I take the OTA.
6. After OTA, I reconnect and see if root(#) is still working. If not, I try the backup root(#). If they are both gone, then I hope the backdoor still works. If not then I flash back to where I was. I then ***** at Lenovo and look for a way to hack it.
Anyway, the backdoor and locking of su are in a script file you can run as long as you have adb working. 99% of the time su stays (because you lock it) or the backdoor works. Also, before taking the OTA you can usually download and see what they are changing. If it breaks root and the back door then what I usually do is pull it apart and build a custom system.img. Inside the OTA zip will be the boot.img. You can actually take it and 'cook' it in your kitchen adding root. Then you take the system.img from a prior release, mount it, and replace all the files with the ones inside your OTA. Make sure you account for blob changes if they are in the OTA. If there's a blob, then put it in the blob tool folder, extract it, and add it to the flash and replace bootloader.bin. Swear some more at Lenovo, and flash in your custom ROM. Now ad su and busybox, and superuser.apk. Use the dump tools in dump folder to build a new system.img. Replace your cooked boot.img with the original OTA boot.img and you're done.
TD.
Then ***** at Lenovo some more lol.
Thanks for the tips, Ill try the script if there is a reasonable update for it ie ICS.
For now the root worked.. flawlessly. Thanks for your work man.
First of all, I like to share I am not a stranger with rooting, flashing, granting bootloader access (not an tablets, but on HTC an SE WM phones in the past (assuming the S-off/S-on switching is somewhat comparable)). Despite not being a stranger, I am no whizzkid either, it's just that I am able to read instructions well, re-read them and carefully follow the instructions step by step. During the process I have reasonable understanding of what I am doing, but I am not someone that could have 'invented' such workflows and adjustments myself.
So, what is new for me? Installing a custom recovery. I haven't done that before. No problem, because I know there are enough techs on XDA that have the great quality to share their knowledge, something I appreciate very much and use regularly.
My story:
Asus created a situation in which you have to register your device and actively decline your warranty, whenever you want to unlock the bootloader. This is why I didn't do that yet. Now, having my TF300 for almost 6 months, reasonably comfortable with the feeling there will be no issues to need the warranty, I am willing to unlock my bootloader and void my warranty. However, shortly after the JB OTA I read a lot of messages that this was not possible with a TF300 on JB. Later I read it might be possible, but that changing the bootloader was not possible. Then I read this was possible too, but you could only install roms based on official Asus JB OTA.
Well... I guess things have evolved since the initial JB OTA, but I am not sure that I understood things well enough to just give it a try (yet). So I am looking for confirmation and a bit more in depth info. First I will summarize my TF300's history in detail and things I found so far regarding custom recovery. In this way you know what the situation is and I also hope this post becomes 'informative' for other TF300 owners too, besides being a question topic for me only.
Ok, what do I have:
- An original TF300T (no dock), bought in June 2012 with stock ICS
- Granted myself root access via 1-Click Transformer Root
- All original Asus OTA's applied, including the upgrade to JB (and succeeding OTA's)
- Still have root (kept root during all OTA's, including upgrade to JB with help from Voodoo OTA rootkeeper)
- Recently wiped/factory reset my device (still have root)
What I used in the past, but currently not running on the tablet:
- Used different Custom build.props on ICS and JB, but now have stock build.prop again
- Used SwitchMe profile manager (still want it, but waiting on decision to possibly unlock/install custom recovery first)
- Used browser2ram (don't want to need it anymore, but ability to boost performance with a custom rom will be a requirement)
What custom recovery options did I see? There are 3 of them and all seem to be safe with the TF300 JB OTA:
- TWRP 2.3.1.0
- CWM 6.0.1.3 / 5.5.0.4 (don't know why it has 2 version numbers... ICS and JB version?)
- Clockworkmod 6.0.1.4 Touch (same as CWM 6.0.1.3 but with touch functionality?)
Ok, what do I want confirmed to be sure enough to give it a shot on my TF300 without bricking?
- Is it possible to use official Asus unlock tool on a stock OTA JB TF300? If possible:
- Are above mentioned custom recovery options indeed safe to run on a (unlocked) stock OTA JB TF300? If safe:
- What is (technical) the best custom recovery option? Or are the mentioned options mostly identical and is it a matter of personal preference?
- Can I run any roms after installing a custom recovery or am I restricted to roms based on official Asus JB?
- What will happen with root access after (if possible) installing a custom recovery? And after installing a custom rom?
These are my major 'need to knows' before I dare....
Besides this information, I am curious if someone can confirm my representation of (or explain) the different parts in Android/Asus installation and how it is affected by a custom recovery. During reading along the forums, I have created this visualization of the different parts of the system:
1. Bootloader or kernel (first thing on system, somewhat comparable with a PC BIOS? Are the terms bootloader and kernel interchangeable?)
2. Asus recovery/boot options or custom recovery (custom recovery replace the standard Asus recovery/boot options, I assume)
3. Android (stock JB/ICS or custom rom)
Is this a correct representation?
Well, that was all... Hopefully my post didn't become a TLDR and some of you are willing to help me out. I am very thankful in advance!
1. Bootloader is something else then a kernel. You just have to have the right kernel for the 2 different bootloader
2. Boot options are in the bootloader. Stock Recovery has no options.
3. dont understand your question
1st if you are still on ICS I would recommend to use NVflash and create the needed NVflash files. After that your tablet is nearly unbrickable and you are able to NVflash back to the ICS bootloader (my opinion not so importent anymore, caus even CM is now compatible with the JB Bootloader)
2nd If you are still on ICS I would use the unlock app on ICS not on JB and would then flash the JB update.
The Custom Recovery is best right now would be TWRP 2.2. Its the only one with no known issues.
Hope that helps a little and hope that my explanations are correct, because I am just a flasher like you
Last but not least. The best ROMs out there in my opinion are the Clean Rom 2.5 for the TF700 with clemsyns Kernel and BlueAndroid V.1.0.
Thank you for your reply, it helps me a bit. Unfortunately it doesn't answer my major questions, but I don't blame you (not at all). Every bit of help is welcome.

That's the point why I started this topic, I am on (stock OTA) JB already. If I was still on ICS, I would have had the guts to unlock and install custom recovery. I am hesitating because I read about issues with JB and unlocking/installing custom recovery.

Yes the unlock tool works on JB as well as ICS. I used it while on JB.
Recovery choose one for JB since you have said you were on JB. In fact that is how you will determine which roms you can use as well (JB).
There have been many complaints posted about problems with CWM on this device.
Safe is something I can't answer - twrp itself appears to be safe but that is relative.
One mistake can usually be overcome (or one weird issue); add a mistake to that and you are out at two strikes with this unit most of the time. That is the way I see it after reading hundreds of posts.
You must have recovery, adb, or fastboot working to recover from a problem with this unit.
Before you make any changes make sure adb and fastboot work.
When you flash a rom make sure early in the game you turn on usb debugging in developer options. Learn to get into and use the bootloader menu for adb, fastboot, and recovery access. This would be with both stock recovery and twrp.
Custom roms are usually by default rooted. With a custom recovery you can flash root at will.
It is long but I feel I touched on each of your questions, if not ask.
If your phone is a ferrari, the kernel is the "driver" ... the kernel you use can be tweaked to allow you to overclock your process. By default, overclocking is not possible (usually) on stock kernels because phone makers don't want you effing up your phone.
Other kernels can let you run "low voltage" or "ultra low voltage" settings for the processor. This allows you to send less power to the processor but still get the same amount of oomph out. The result is greater battery life, and no cost to performance. Obviously this can be dangerous to some hardware... so be careful and know what you're doing. It can be as bad as damaging hardware, or as minor as getting your phone stuck in a boot loop. DO A BACKUP with Rom Manager before installing a kernel. Always do a backup before you do anything to your phone.

Thank you for this clear answer. Allow me to summarize your answer (actually it is a confirmation request to see if I fully understand your answer):
- Asus unlock tool is working fine on JB, no problems
- Since my TF300 is on JB and to stay on the safe side (no guaranties) your advice is to use TWRP 2.3.1.0 for JB (to use the JB version is obvious for me, thanks for confirming)
- Once these steps are done (unlock and custom recovery) , I can flash roms at will, but have to keep in mind to use JB-based roms
Did I summarize (and thus understand) your answer correct?
Thanks for pointing out to have adb and fastboot working before making changes and to learn to get into and use bootloader menu for adb, fastboot and recovery access (with both stock recovery and twrp). I am very much aware of this, but it is always wise to make that clear to anyone whom wants to play with this stuff.
You helped me very much! To be complete sure, I'll wait for confirmation, but then I have more than enough confidence to give it a go (Yes, I will beware it won't exaggerate into over-confidence and I become sloppy . I'll stay punctual and cautious during the process.).

Can I see the kernel somewhat equal to the bios on a pc, or is that a misinterpretation?
If I understood it correct, then it is not fully comparable to a pc bios, as on Android the kernel also determines which version of Android is able to run on your device (ICS needs another kernel than JB), right?

BIOS (basic input-output system, or something along those lines) is loaded before the kernel! They are different. The kernel acts as a mediator between hardware and software.

Why should I unlock?
The explanation to this question is really simple. If you want root, you’d be wanting to flash Custom ROM post-root, and if you want to install a Custom ROM, you’d need to have your stock bootloader unlocked. In simple terms Unlocking the bootloader allows you to install custom Firmware on your Android phone
Warning: Unlocking your phone’s bootloader voids its warranty. It also completely wipes (formats) your Android phone’s internal memory including applications, contacts, SMS and MMS messages etc.

kexec is required to flash a kernel.
Safestrap is a way to flash somewhat custom ROMs (without kexec you need to use stock kernel) without recovery installed but it needs to be adapted to each specific phone. Right now I think they are working on a version that will work with the S4, not sure how attractive the G2 is (or will be).

You guys first need Root to do anything (which i believe you have). Then you need a Custom Recovery. Installing a Custom Recovery can be accomplished via a workaround or by unlocking the bootloader. A workaround like loki by djrbliss on the Galaxy S4 which isn't an unlock but more so a bypass or like Safestrap by Hashcode.
Here is the man djrbliss.

i completely agree with the said explanation. but I'm having difficulties with my device i.e. LG G2 (D802).
I'm rooted with custom recovery TWRP and unable to install most of AOSP roms based on 4.4 KitKat. New Custom roms are coming up very frequently now for this device but so far I'm able to flash ParanoidAndroid Rom and modifited stock rom... Apart from this I always gets error while flashing the rom.
Most of the time Error comes up saying 'Status 7 Error' and 'unable to execute update binary'.
I did google on this subject and tried everything i found but the problem still exist.
I never had these problem flashing LG Stock or Android 4.3 based roms. Need advise on this subject. By the way any help on unlocking the bootloader????

I have come across some very cheap Galaxy Tab 4's on eBay that I was wanting to try out. I'm a T-Mobile customer so I'm interested in the SM-T337T (band 12 support woo hoo!)
I see that there are recoveries for the tablet so it looks like I'm not the first to wonder.
Basically, my question is: which Lollipop/Marshmallow ROMs are currently supported and stable on the SM-T337T? And have we been able to reliably root/install recovery on them?
Thanks,

Unfortunately there are no custom ROMs for the SM-T337T. There has been an official lollipop update, and since there are working recoveries, you should be able to use chainfire's systemless superSU root method (you most likely need the systemless root because the lollipop update is 5.1.1). The fact remains though that nobody has made a custom ROM for this tablet. Sorry

Thanks for the reply. What can I do to help the situation? What would be required on my end to port a different ROM to it? Either from a "stock" Cyanogenmod or from an existing Galaxy Tab 4 ROM?

For cyanogenmod you'd need a computer running linux, whether in a virtual machine or dual booting windows and linux (I have that setup on my Windows laptop, Ubuntu works fine), you'd need to set up your build environment, sync the necessary repos from Cyanogenmod's github, you may or may not (but probably will) have to create a device tree, but I imagine you can probably use moonbutt74's github repos to get you started on that, and once all that preliminary work is done you'll have to figure out what proprietary files are needed from the Tab itself. And of course it would be a good idea to download and inspect Samsung's source code for your device. If you have no idea what I'm talking about, this would be a good place to start reading: https://wiki.cyanogenmod.org/w/Development#Learning_To_Build_CM
Thank you for the very thorough response. I just don't wanna be "that guy" who gets on here and says "Waaahhhh the devs aren't supporting my device!" I'd rather help
When I get home in a few days, I'll fire up the build environ and see what I can do with her. Here's hoping no bricking!

I have that device on 5.1.1 and rooted it here(in case you haven't found this yet);
//autoroot.chainfire.eu/
Root available for both 4.4.4 & 5.1.1.
I would personally love to see marshmallow on this device! Currently settling for some Touch-Wiz debloating for now.
Does anyone have updates on this? I recently got an SM-T337T and would like to de-bloat it -- first on the chopping block would be TouchWiz. If there's a ROM that takes care of this, that would be nice, but I might be able to do it on my own?
Also, I'd really like 6.0.1, instead of 5.1.1 that's currently on it.

Just picked one of these up for Mom and have rooted and flashed TWRP, but was wondering if anyone knows of a ROM or at least debloating scripts...?
Thanks!
Hey Coach,
I know this thread is quite dated but just hoping you might have succeeded in either creating or finding a custom ROM for this device? I'm still using mine but finding more and more apps no longer supported on 5.1.1.
Thanks!
Hi. This is a general question... Tomorrow I'm buying a J5 Prime SM-G570m, and it's going to be my first samsung device (and 3rd android device). From my experience, I know that Samsung always modifies a lot of their stock ROM, and many things that work in most android devices, don't work in a samsung one.
I've searched about the J5 prime and there is not much development or guides about it (I hope that changes, because I love to root and modify and install xposed), but in case I soft brick my J5 trying to root it, is there some easy way to reflash and get to stock ROM again and unbrick it?
I know this is probably a noob question, but I know almost nothing about Samsung rooting and modding and just wan't to be sure that anything that is not a hard brick can be easily fixed in these devices too. Thanks for any answers
Samsung Smart Switch, see how to flash/restore Stock Rom here

You can flash stock rom with Odin and root the device. Xposed only available on Android marshmallow. If you want to buy J5 prime and expect for custom rom support, you make a mistake. There's no active development for J5 prime.

I would love to see CROM support for the prime, but I can live with root and xposed only

Cool, I don't have root yet, I'm waiting a little more time before voiding my warranty but I've read some users install wanam version of Xposed. The normal version doesn't work with Samsung?

Never tried the normal one but wanam version works. And systemless xposed via magisk manager also works 100% if you have telegram you may message me http://t.me/dikketesla
