Windmobile 2.3.6 GS4G won't root

Superclick won't root. It goes through a bunch of stuff, does the sleep, sends the zerlings, sleeps, sends more, then the software freezes at the end with the window "not responding" and the phone isn't rooted. Trying a shell root first, it goes through the same stuff, sames something about blue flames, then goes back to letting me click buttons.
Is 2.3.6 not rootable?

Have you tried using ODIN to flash one of the rooted kernels?

I know there is that option or the option of the One-Click to install a new room, but since their is some debate if the bootloader of the Wind version is different than that of the T-Mobile that all the stock kernels are based on, I'm still searching and reading first to see.
Do I have to flash a bootloader to use the the One-Click to install stock rom so I can then have it rooted, install CWC, then flash a rom I want?

Let ask this what is your intentions with rooting?
If you want to install a custom rom Click on the purple link in my signature.
UNDER NO CIRCUMSTANCES FLASH BOOT LOADERS
Then you can flash any of the current ICS flavors, CM7, or the current stock based roms.

Well was looking through some of the tut's and the one was how to do flash with no bootloaders via the phone, but needed root.
....So, If I use the 1 click in your link and run the jar file, that will flash me to a stock rom that is rooted with the clockwork recovery correct? I don't need to run the 1 click again and flash the bootloader for any reason to get the above?
Then from there, I can flash any cm7/cm9/acid/stripped down/whatever rom I want?
There is no way to backup my current system as is though, correct, because once I go through the 1 click, I'm flashing the stock bare bones rom to it?
I have no problem flashing and have done other phones and modded thousands of game consoles, but want to be sure this goes well. I've had the phone for a total of 30 hours and don't want to toast it.......but I like to tinker. lol.

Meh. Already bit the bullet and did it and booting your ICS as I type this. lol. The phone is 36 hours old, that's old enough to be modded isn't it?
Thanks for all the work.
Now I did the 1 click, went to recovery, did a backup of my system at that point, installed your ICS, gapps, fixxed permissions, etc, etc. Now If I want to go back to the 2.3.6, I can restore my backup right? that is going to be as close as I could get, which I would have to run the wireless fix to get wireless working since the 1 click installer's stock rom is very basic.

i was in the same boat as you i try three different version of SOC and finaliy manage root it with superoneclickv2.3.1-shortfuse.the only thing i notice was when it was installing root it stalled in step 5-6 and then it did it i got root.also make sure u have OEM cable for your phone

No you will have to flash the one click again. Just dont flash bootloaders. In your case make sure you always flash the roms for the sgh-t959v/w otherwise your liable to have a paperweight. Unless you can get a mini keis tarball for bhundven from wind mobile tech support.
If you like to tinker and think you might be able to get them to do this hop on irc before downloading the stuff. That way bhundven can walk you through getting it to him so he can perform surgery and compare the bootloaders.

thanks, and thanks for the 1 click!
Is there anyway to tell if a ROM has bootloaders or not? I've only been looking at "V" roms anyways from the list of SGS4G roms on the wiki, so think I'm safe there, just not sure about how to tell if they have a bootloader or not?
So far, the cyan/ICS/Team Acid one is working pretty good. Wifi was boinked and wouldn't authenticate any connections but a factory reset from within Android fixed that and been rock solid since.

As long as you are flashing the rom via cwm your safe. However flashing using heimdall or odin sometimes has bootloaders included. The one clicks include bootloaders but you have to check the option and then there is a secondary confirmation you have to click on. So again just flashing back to stock without touching the flash bootloaders option you are safe.

Ok, thanks. I only used odin a few times on some bricked phones customers brought me.
Wifi seems to be going wonky again with the ICS. Not connecting after a while. Better rom's to try or just a known issue or something I can try or do?

Best thing to do is get some logs for bhundven to look at. I use cm9 currently and wifi like 90% of the day. and I dont have problems with wifi.

Replaced my older router with a new one, was still having issues but reset all the ddrwrt settings to stock, re-setup the wireless step by step, testing on phone and laptop each step of the way and seems to be going good so far, full wifi bars, connected at 54mb. Now to move the N router from the basement so I can get N speeds. lol.

The wifi on the phone only does 2.4GHz N-mode.
The only phone I've noticed 5GHz N-mode on is the galaxy note 2 (so far).

Ok, I'll make sure to set the router for 2.4ghz mode when I set it up. Thanks for all the work on this and the help in the threads you've answered in. guess I just got freaked over the whole bootloader thing, but I have a good handle on hows it's working now somewhat anyways. Everything is going pretty good and I like being able to use Chrome now, with the desktop sync tabs and stuff. Can pickup in another room what I was doing on my PC and stuff. Pretty cool. I'll check out how the GPS works compared to the stock rom was today, but wifi seems to ok since I replaced that old crappy router. Good thing about running your own electronics repair stuff, always another router somewhere in a box. lol.

[Q] Galaxy SII Model SGH-S959G

I just got a Straight Talk Samsung Galaxy SII Model SGH-S959G and their is basically nothing as far as hacks for this phone, yet.
My first question is what needs to be done to obtain root?

You can root this phone using Entropy's kernel: http://forum.xda-developers.com/showthread.php?t=1289460
And you can flash it with Odin: http://forum.xda-developers.com/showthread.php?t=1738841
I wouldn't though. You can't install a customer recovery on this device right now and nobody has figured it out yet (that I know of).

Are you sure my kernel is safe to use on this device???
There is little known about this device... Going by name alone is a VERY BAD IDEA on Galaxy S2 era devices. Flashing I9100/I777 stuff to any Qualcomm based device would guarantee a hardbrick, and I think going the other way would hardbrick you too.
Since it's 4.3" screen it might be an Exynos device, but no guarantees. Specs/features don't mention NFC at all, so it may be more similar to the I9100 than I777.

I've been using your kernel for over a month without any major issues. The phone boots fine, plays games. The only issue I've run across is that sometimes you have turn the wifi on and off, but I don't know if this is the device itself (you mention something about wifi deep sleep in your thread) or if it's just an issue with my router (I've experienced similar things in the past with other routers and devices, so I really don't know).
About the NFC. If you remove the battery cover and look at the factory sticker for this phone, it has the same FCC designation at the i777 and the battery says NFC everywhere. I think TracFone simply has it disabled in the firmware similar to how they've locked the device from Kies and tethering.

IndigoAK, just to make sure we are on the same page, you have the SGH-S959G model?

So why did you claim earlier no one had a custom recovery for this phone, if my kernel works fine?
It sounds like this device might be identical to the I777, so you *might* be able to flash anything meant for I777.
Have you tried flashing any ICS firmwares? Do you have a dump of the stock /system firmware?

Yes. This is the model I have
@Entropy: I said that because I've not seen anyone that's been able to install custom recovery for this phone. Your kernel installs and it successfully roots the phone, and the wifi works unlike the zedomax kernel, but if you enter recovery it's just the stock recovery and if you try to install recovery through ROM manager or whatever, then you can't. I might not even be doing it right. I'm not exactly an expert on this and to be perfectly honest, I'm learning as I go here since this is my first Android device. Also, I don't have a dump of the stock firmware and nobody else does either as far as I'm aware. The source code for this device is available from Samsung's open source website, but that's apparently not the same thing.
When I say fine, I mean my phone doesn't blow up or hang or generally do anything un-phony. It boots, it makes calls, it plays games and installs apps, it mounts my sdcards, it connects to my computer through USB using Windows.
The only things is doing do are NFC, tethering and connect to Kies, which as far as I know you can't do even with the stock device, so I doubt that's your kernel.

OK that's REALLY strange, because recovery is contained within the main kernel on this generation of devices... Unless this model is a MASSIVE fluke and the recovery partition actually does something. (It doesn't on any other Exynos galaxys2-family device.)
NFC and tethering is likely to be an issue with the /system contacts...

Yeah, booting into recovery in your kernel gives the basic options. Reboot, reset. Nothing about flashing or backup. I haven't tried to flash the clockwork mod kernel from your thread since I've had such bad luck with kernels in general. Trying to install clockwork recovery from inside ROM Manager gives an error on reboot, but if you reboot again everything works fine, even the normal recovery

Yes. I've successfully used Odin 1.85 and Odin 3.07. Mobile Odin doesn't work (or I haven't figured out the right settings).

I'm surprised that there isn't a big hacking community for this device. I mean it's one of the best prepaid devices on the market with 45$/month fast HSPA+ service..
Hell, the Motorola Triumph was a junky PoS but had a very large dev team.. I would love for someone to get a root working on this phone, and it seems I am going to try to flash Entrophy's rom as WiFi works with him as you said..
C'mon guys, wheres all the dev teams at?

IndigoAK what one of Entropy's kernels did you use? The .tar one? Can you use the zip files in Odin?

I used the latest version available in his thread. It's from March I believe. Also, Odin doesn't support zip files when flashing from a computer, tarballs only. I couldn't for the life of me manage to make a tarball in Windows that Odin would read though, so I had a friend package it for me.

Crap, I used the tar one and flashed it. With root checker it says I dont have root but busybox is installed. When it boots it shows the yellow triangle with ! but the phone boots and works okay.
Or can I get a copy of your tar?

Not too sure how I can help but I if there's anything I can do to help you guys out with this phone I'm willing. I'm not very familiar with flashing and rooting and stuff, since I've never done it, but I'm a pretty quick learner so I'm sure with a little help I can. I just got a new Samsung SGH-S959G, I have turned it on and connected to my wifi but that's it, I haven't activated it or anything. Let me know if there's anything I can do to help out, and how I would go about doing it.

Hey Roxanne, welcome! The best thing you can do to help us right now is leave your phone stock so we have someone who has the original files in case we screw something up. Right now there is no real benefit in hacking this phone but hopefully soon what the few of us are doing will lead to cool new stuff for this model.
Right now the best thread for this phone seems to be at the link below:

Constant Switching from 4g/3g/edge

So I have used TMOUS rom for ALONG time and recently decided to switch to use Cyanogen being a fan of it form other platforms.
While on the TMOUS rom I had 4g connectivity in my area about 90% of the time with the occasional drop into 3g here and there. It always displayed a 4g image in the top.
When I switched to Cyanogen that pretty much stoped. It always says 3g and is slow as hell. every once in awhile it will say H+ but not for long. MOST of the time it is constantly switching between 3g/4g/edge then shutting off.
Now im not sure if its a rom problem or not, but its making me want to switch back to a TMOUS rom.
Any suggestions would be great!
Edit: Just for clairification, I am S-On

I have this problem as well. I even ran the ruu back to stock and it is still happening. Please and thank you!

Unfortunately, it doesn't seem to be a hardware problem
I have been trolling the net for weeks but have not found a solution yet.
I've posted in threads here but no solution.....
My issues started when I went to CM ROM - I used to have great 4g all the time before I went to custom rom (I was on stock TMO US) .. Now no matter what I do, I am not able to get 4G again.... it's really irritating...
I've tried a bunch of custom ROMS.. I am on 1.13 HBOOT and S-ON .. .. CID = HTC__001 (originally my CID was stock TMO US CID whatever that is but now its not that.. I don't wan to run RUU because I don't have TMO US CID and dont want to brick my phone)

You can set your CID back easily with the All in One ToolKit found here.http://www.hasoon2000.info/getdownload.php?file=One%20S/One_S_All-In-One_Kit_v4.0.rar
That is not the problem, unfortunately. It just doesn't make much sense, whatever the problem is; and especially considering after a full RUU restock. That has always fixed whatever mess I have created in the past.

This rom should fix your problem. Dont forget to clear storage from bootloader. It will erase everything thoug. And follow the steps under show contents link.

I not sure if its a CID problem. The only thing I ever did was upgrade to the newest Hboot and load in the CM rom. even going back to the TMOUS rom does not fix the problem.
Its so bad, and never on 4g that im considering getting a new phone.

I'm in the same boat, friend. I've tried literally everything suggested, I'm just wondering what exactly happened in the flashing of the Maximus rom. The worst part being is that I GET 3g/H and then it drops back to E. It's so strange. The only thing I've not done is contact Tmobile about it, and i highly doubt that they would throttle my bandwidth without contacting me in some form or fashion.

From what I've read, it's doable; even with an unlocked phone. But I'd really like to know what in the dev's source code made this happen... it's a bit ridiculous.

I did this the first time, but i just flashed the rom with a full wipe.
This time what I did was go into TWRP and erased everything....and I mean everything except TWRP.
After that i flashed the rom and boot.img and everything works great. 4g all the time again!

So what I did first was go into TWRP and selected wipe. Inside wipe i selected EVERYTHING, every little box. Then Wiped it.
This left nothing on the phone but the recovery. I then loaded on SuperSU from TWRP. I download the stock TMOUS rom that was posted earlier in this post.
In TWRP I mounted it and hooked it to computer and transfered the rom over.
Once the rom was on I did the install of the rom.
I rebooted the rom into bootloader.
Once in bootloader i put it into fastboot.
I had previous extracted the boot.img from the rom.
I sent the boot.img over via fastboot which restarted the phone.
Once it got all started up. No issues. I am on 4g 99% of the time now.
Im thinking the issue was definatly based in the CM rom.
Since this worked I wanted to test things out since my phone was pretty much stripped of everything.
I tried out Viper rom and a couple of other non CM based roms, and I have had no issues.
IM back on teh TMOUS rom though. Wifi calling will win over when i go overseas.

Thanks, but it did not work for me. It is a hardware issue on mine. Thanks again

Must be.
I did find something out though doing all my research. Did you ever at any point update the radio? TMobile uses some frequencies that some companies dont use.
It is my understanding that some of these roms are packed with radios that are generic and thus ment for multi carriers.
Not sure if thats your issue, but might want to look into.
Its nice being back on 4g though.

[Q] 4G/LTE band missing

I was experimenting my M8 with T-Mobile sim card. I flashed 5.0.1 GPE ROM and everything worked fine. I also changed its CID to T-MOB010 and flashed ViperOneM8 3.2.1. It worked fine as well. But after I reverted everything back (by loading 3.28.605.4 0P6BIMG and firmware, and restoring a TWRP backup), I discovered I can no longer get 4G/LTE signal. I can only get 3G. I tried flashing to RUU M8_VZW 4.4.3 (firmware &0P6BIMG). But it doesn't help. I dialed *#*#4636#*#* but didn't see any option/menu. When I use 4G Switcher app to select band, 1900MHz band isn't available. The network type is set to "CDMA/EvDo/GSM/WCDMA/LTE auto". I am using CleanROM 3.0. Any advise will be greatly appreciated.

Sent from my HTC6525LVW using Tapatalk

I understand completely where you are coming from. I flashed the same rom and my phone stop connecting to LTE when in global mode. I have flashed the 4.4.2, 4.4.3, and 4.4.4 RUU and went into the stock recovery and did a factory reset and it still does not work.
Right now I am running cleanrom 3.0 also. The only time I can get LTE is when I go into settings and switch it to LTE only.
The only thing I think it can be is when I do the factory reset on the RUU, the says restoring Verizon NV flash rather than formatting it. I want to try and flash a T-MOBILE RUU to see if it will format it and clear it out then switch back to Verizon but I don't know if that will brick my phone. If I can't find a way to wipe the NV the only thing else to do is run the phone over with my car a couple times then claim warranty.
Not trying to knock digital high's rom because he and several others put a lot of work into the stock 5.0 rom and I really appreciate the effort, but I wish I didn't flash it because I think there is an underlying issue with the rom that is affecting a small portion of our phones. And it is so small that there is no support to fix it. I have scoured the forum to find a fix and nothing has worked so far. But these are the problems we accept when we hack our phones and flash non factory software.
I hope you find a fix and if you do please let me know. Good luck.

Factory reset using stock recovery does the trick. 4G/LTE is back. Thanks a lot for the suggestion. Much appreciate it.

I'm having the LTE issue as well. I'm currently running DigtalHigh's GPE 12/18 release with the updated firmware. LTE works on first boot until I connect to my Wi-Fi network, after that I never see LTE again. I tried everything, and I mean everything. I tried the RUU back to 4.4.4 and doing a factory reset from that... I get the same result, LTE on 1st boot until the WiFi connects and then it's gone for good again until the next complete reset.
The most recent thing I tried was replacing the SIM card (while on the GPE rom)... this worked flawlessly. I had LTE again for a few days... until I made a phone call from my car using Bluetooth, at which point the phone geeked out, switching from speaker to line-out to bluetooth audio and eventually dropping my call (not sure if that is somehow related to the LTE issue), but now I'm back to no LTE again.
But I get full bars of 3G, so I've got that going for me... which is nice.

Is it possible for you to put in a new SIM while on another Rom like clean rom to see if LTE will stay?

DH GPE with custom firmware has hooped the VZW LTE radio settings, it has overwritten them...no amount of custom rom re-installations will fix this.
As stated above, the easiest way to fix this is to simply flash a stock Verizon RUU, and THEN do a factory reset from the stock recovery. I used http://forum.xda-developers.com/ver...ent/ruu-m8vzw-4-4-4-s-off-onlynewest-t2914914 with the SD card method and it worked fine.
After you do the stock factory reset you can then install DH GPE again, without using custom firmware.

I tried installing the stock ruu and using the stock recovery to fix it. It hasn't worked. Did you use the method of installing through the phone or the computer?

I put 0P6BIMG.zip in ext SD card and booted from HBOOT.

My LTE just automagically kicked back on after I reset it three weeks. Glad it doesn't have to meet the tire of my car. I pray it stays on

I posed this question on another thread, but I'm trying to understand what you mean when you say "stock recovery". I know what it is, but what I don't know is what stock are you referring to; do I have to downgrade to 4.4.4 or when you mean stock it doesn't matter if it's Lollipop 5.0.1.? Thank you sir!

I mean the matching HTC provided recovery img for the firmware version you are on.

Boy this horse is getting beat to death. Go to Dottat's RUU posts where he explains it all. I used the 5.0.1 S-Off one. Once it's installed, boot, and then reboot to it's stock/factory recovery and do a factory reset. That will fix your 4G/LTE problem. Then you get root back and flash a "custom" recovery like TWRP. I followed the Sunshine instructions. If you don't want/need root or TWRP skip it and you'll have an S-off stock not rooted phone.

It's been a few years since I wore my horse, the HD2 to death and I didn't stumble on to the cure until the wee hours this morning. It eventually comes back and like the wife hitting your head with the iron skillet...ding, ding, ding....external micros SD card and RUU; I remember how to do that. I'm S-Off, this will work. What I didn't know is what is "stock"; factory state you walked out the store with or matching the ROM to the firmware and if I'm going to downgrade to reset the NV configuration, what all that entails. It's the jargon, I need to learn and that takes time. I sincerely appreciate what the OPs do and where they direct me to; thanks!

Answered this once already in the last 24 hours and this will be the last time.
Stock recovery is the matching HTC provided recovery img that is from the matching firmware version you are currently on. If you are on 1.X firmware it's best to find stock recovery from the 1.X ruu or firmware zip file.
Stock recovery is only provided by HTC.
Why is this so dang difficult to understand folks and why does the question need to be repeatedly posed?

Point is the information is already out there. Nothing misleading about it.
There are some basic premises that better be understood first lest he avoid failure by leaving that boot loader locked and s on.
Capiche?

Because, those of us doing the asking while we truly and sincerely appreciate the work all of you do, and believe me "I" do, some of you, not all of you completely fail at the teaching aspect of the knowledge you possess. That said, thank you very much; it worked. I can't tell you whether it was the factory reset or performing the edit inside ##778; the moment I put the wife's Straight Talk (Verizon) SIM card in; 4G LTE returned. I did not have access to the dial code until now. Again, thank you!

HTC - No signal... Ever

Hi,
I can't seem to get any signal, can't call text or use data on my HTC desire 620. But it is finding the networks as when I search to select networks it can find O2 (I'm on giffgaff. And it claims to have registered on network. I've refreshed back to stock,but I don't know where to go from here.
Do I need to reflash the radio.img? If so how would I go about doing that? I've searched allover but can't find the file online.
Thanks

The easiest way to fix your issue is to factory reset it, if that doesn't work, then restore your phone entirely using the stock files, IF that isn't something you want to do then yes, flash the radio and flash the modem as well. It can't hurt.
In most cases just start back at square 1; going entirely back to stock. In so many cases that will fix your issue the fastest.

Thanks for the reply,
I've flashed the stock rom already, but that didn't seem to fix it.
But I read somewhere that flashing a stock rom doesn't actually flash the radio or modem, just the system, boot and recovery.
In which case do you know where I could find a download for the modern and radio?
Thanks

Jessooca said:
Well if you want to be certain you have your phone entirely back to stock...
Factory reset the phone.
Power it off, and reflash the stock files
Flash the modem and radio
Once it powers back up factory reset it again
Let me know what happens after that, I'll look into your particular HTC so I can help you fully this evening, Get back to me after you've done the above again, even if you've already done it already.

I've flashed and reset everything except the modem and radio, as I'm still searching for the files. Is there anyone with this device who could upload their's. It is the HTC desire 620, unlocked from H3G (Three).

Hmmm, that's odd.
What's your device model (country as well; us version? India? Etc) what's the latest firmware and boot loader you know you were on?
Have you flashed all of the latest updates for your phone? I ask because if you've updated and you're using a previous version to try to fix your phone, that will not work.
Let me know all the pertinent details about your device and firmware/bootloader so i can provide a bit of better assistance
